    Summary Background and objectives Demand for hemodialysis among elderly patients is increasing worldwide. Although clinical care of this high-risk group is complex and challenging, no guidelines exist to inform hemodialysis practices. The Dialysis Outcomes and Practice Patterns Study (DOPPS) provides a unique opportunity to assess dialysis practices and associated outcomes among elderly versus younger patients on chronic in-center hemodialysis in 12 countries. Design, setting, participants, & measurements Clinical characteristics, dialysis practices, and outcomes of elderly versus younger patients were compared among participants in four DOPPS regions in 2005 through 2007. Results Although participant mean age increased over time in all DOPPS countries, the percentage of elderly varied widely. Overall, comorbidities and malnutrition were more common in the elderly. Fistulae were used less frequently among elderly versus younger patients in Europe and North America but not in Australia, New Zealand, and Japan. No difference in treatment time was observed between elderly and younger patients after normalizing for body weight. In all regions, ultrafiltration rates were lower among elderly patients. Elderly patients reported poorer quality of life with respect to the physical but not mental component scores. Mortality risk was three- to sixfold higher in the elderly group, whereas causes of death overall were similar for elderly and younger patients. Conclusions Elderly patients represent a different proportion of DOPPS participants across countries, possibly reflecting differences in policies and clinical practices. In general, hemodialysis practices in the elderly reflected each region's clinical patterns, with some variation by age group depending upon the practice. PMID:21734085

    Large cohort studies suggest that high convective volumes associated with online hemodiafiltration may reduce the risk of mortality/morbidity compared to optimal high-flux hemodialysis. By contrast, intradialytic tolerance is not well studied. The aim of the FRENCHIE (French Convective versus Hemodialysis in Elderly) study was to compare high-flux hemodialysis and online hemodiafiltration in terms of intradialytic tolerance. In this prospective, open-label randomized controlled trial, 381 elderly chronic hemodialysis patients (over age 65) were randomly assigned in a one-to-one ratio to either high-flux hemodialysis or online hemodiafiltration. The primary outcome was intradialytic tolerance (day 30-day 120). Secondary outcomes included health-related quality of life, cardiovascular risk biomarkers, morbidity, and mortality. During the observational period for intradialytic tolerance, 85% and 84% of patients in high-flux hemodialysis and online hemodiafiltration arms, respectively, experienced at least one adverse event without significant difference between groups. As exploratory analysis, intradialytic tolerance was also studied, considering the sessions as a statistical unit according to treatment actually received. Over a total of 11,981 sessions, 2,935 were complicated by the occurrence of at least one adverse event, with a significantly lower occurrence in online hemodiafiltration with fewer episodes of intradialytic symptomatic hypotension and muscle cramps. By contrast, health-related quality of life, morbidity, and mortality were not different in both groups. An improvement in the control of metabolic bone disease biomarkers and β2-microglobulin level without change in serum albumin concentration was observed with online hemodiafiltration. Thus, overall outcomes favor online hemodiafiltration over high-flux hemodialysis in the elderly. Copyright © 2017 International Society of Nephrology. Published by Elsevier Inc.

    In December of 1999 and 2000 we visited all hemodialysis centers of Lithuania and collected data about all hemodialysis patients, using special questionnaires. The aim of the study was to evaluate the relationship between lethality of hemodialysis patients, erythropoietin dosage for renal anemia treatment and hemodialysis quality. The patients with higher Kt/V, higher levels of iron and albumin, normal levels of phosphorus and parathyroid hormone (PTH) requested lower doses of erythropoietin (analysis of the patients who were on hemodialysis in 2000 more than 6 months). So, we can conclude that adequate hemodialysis procedure and good management of hemodialysis patient are leading to the decrease request of erythropoietin doses for anemia treatment. We compared two groups of patients in order to examine relationship between hemodialysis quality and lethality of hemodialysis patients. We selected incident patients registered in December of 1999 and we divided these patients in December of 2000 in two groups: a) 175 patients, who continued hemodialysis treatment and b) 41 patients, who died in 2000. The results revealed, that dead patients were elder, their duration of weekly hemodialysis was shorter, Hb concentration lower, they had worse nutritional status (blood albumin level was lower). Lethality was associated with underlying diseases such as diabetes, hypertensive nephropathy and renal amyloidosis.

    The utilization of peritoneal dialysis decreases with age. A number of concerns have been raised regarding the suitability of peritoneal dialysis for elderly patients. The purpose of this review is to determine whether these concerns are medically valid. Literature review and synthesis. Most elderly patients possess the manual and cognitive skills necessary to perform peritoneal dialysis. Elderly patients on peritoneal dialysis exhibit excellent compliance with their treatment regimen and display no increase in the rate of infectious complications though they may have a slight increase in hospital days. They easily achieve adequacy targets, experience good technique survival and their nutritional status is at least as good as that of their hemodialysis counterparts. Patient survival varies around the world but is overall comparable to that of age-matched patients on hemodialysis. Quality of life may be somewhat superior to that of older hemodialysis patients. Elderly patients with end-stage renal disease are appropriate candidates for peritoneal dialysis. It is not medically justifiable to exclude them from consideration for this therapeutic modality.

    The chronic kidney disease is a major health concern. The number of the elderly people with chronic renal failure has increased across the world. Dialysis is an appropriate therapy for the elderly, but it involves certain challenges. The present paper reports uncertainty as part of the elderly experiences of living with hemodialysis. This qualitative study applied Max van Manen interpretative phenomenological analysis to explain and explore experiences of the elderly with hemodialysis. Given the study inclusion criteria, data were collected using in-depth unstructured interviews with nine elderly undergoing hemodialysis, and then analyzed according to Van Manen 6-stage methodological approach. One of the most important findings emerging in the main study was "uncertainty", which can be important and noteworthy, given other aspects of the elderly life (loneliness, despair, comorbidity of diseases, disability, and mental and psychosocial problems). Uncertainty about the future is the most psychological concerns of people undergoing hemodialysis. The results obtained are indicative of the importance of paying attention to a major aspect in the life of the elderly undergoing hemodialysis, uncertainty. A positive outlook can be created in the elderly through education and increased knowledge about the disease, treatment and complications.

    The prevalence of sarcopenia on elderly maintenance hemodialysis (MHD) has been scarcely investigated. To investigate the prevalence of decreased muscle mass and strength alone or combined (true sarcopenia) in elderly patients on MHD according to different methods and cutoff limits. Additionally, we evaluated the agreement between dual energy x-ray absorptiometry (DXA) and surrogate methods for the assessment of muscle mass. Observational and cross-sectional study. Non-institutionalized 102 elderly (age > 60 years) patients on MHD. Sarcopenia was considered when the patient fit one criteria for low muscle mass assessed by DXA, bioelectrical impedance (BIA), sum of skinfold thicknesses (SKF), calf circumference and mid-arm muscle circumference (MAMC) and one for low muscle strength evaluated by handgrip dynamometer. Decreased muscle strength was found in 85% of the patients. The prevalence of decreased muscle mass varied from 4 to 73.5% and of sarcopenia (decreased muscle mass and strength combined) from 4 to 63%, depending on the method and cutoff limit applied. A small percentage of patients (2 to 15%) were classified as sarcopenic by more than one diagnostic criteria. The agreement between DXA and the surrogate methods to assess muscle mass showed better kappa coefficients with BIA (r=0.36; P<0.01) and SKF (r=0.40; P<0.01). A wide prevalence of sarcopenia is observed depending on the method and cutoff limit applied. This may limit extrapolate on to clinical practice. BIA and SKF were the surrogate methods to assess muscle mass with the best concordance with DXA in elderly MHD patients.

    Background Patients undergoing hemodialysis are at high risk of falls, with subsequent complications including fractures, loss of independence, hospitalization, and institutionalization. Factors associated with falls are poorly understood in this population. We hypothesized that insights derived from studies of the elderly might apply to adults of all ages undergoing hemodialysis; we focused on frailty, a phenotype of physiological decline strongly associated with falls in the elderly. Methods In this prospective, longitudinal study of 95 patients undergoing hemodialysis (1/2009-3/2010), the association of frailty with future falls was explored using adjusted Poisson regression. Frailty was classified using the criteria established by Fried et al., as a combination of five components: shrinking, weakness, exhaustion, low activity, and slowed walking speed. Results Over a median 6.7-month period of longitudinal follow-up, 28.3% of study participants (25.9% of those under 65, 29.3% of those 65 and older) experienced a fall. After adjusting for age, sex, race, comorbidity, disability, number of medications, marital status, and education, frailty independently predicted a 3.09-fold (95% CI: 1.38-6.90, P=0.006) higher number of falls. This relationship between frailty and falls did not differ for younger and older adults (P=0.57). Conclusions Frailty, a validated construct in the elderly, was a strong and independent predictor of falls in adults undergoing hemodialysis, regardless of age. Our results may aid in identifying frail hemodialysis patients who could be targeted for multidimensional fall prevention strategies. PMID:24131569

    Purpose Treatment intensity for elderly patients with end-stage renal disease has escalated beyond population growth. Ageism seems to have given way to a powerful imperative to treat patients irrespective of age, prognosis, or functional status. Hemodialysis (HD) is a prime example of this trend. Recent articles have questioned this practice. This paper aims to identify existing pre-synthesized evidence on HD in the very elderly and frame it from the perspective of a clinician who needs to involve their patient in a treatment decision. Patients and methods A comprehensive search of several databases from January 2002 to August 2012 was conducted for systematic reviews of clinical and economic outcomes of HD in the elderly. We also contacted experts to identify additional references. We applied the rigorous framework of decisional factors of the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) to evaluate the quality of evidence and strength of recommendations. Results We found nine eligible systematic reviews. The quality of the evidence to support the current recommendation of HD initiation for most very elderly patients is very low. There is significant uncertainty in the balance of benefits and risks, patient preference, and whether default HD in this patient population is a wise use of resources. Conclusion Following the GRADE framework, recommendation for HD in this population would be weak. This means it should not be considered standard of care and should only be started based on the well-informed patient’s values and preferences. More studies are needed to delineate the true treatment effect and to guide future practice and policy. PMID:23847412

    The hemodialysis (HD) diet, which is a high-calorie and high-fat regimen, may inadvertently lead to an inadequate dietary intake, resulting in undernutrition among elderly HD patients. Therefore, an attempt was made to improve the dietary intake by implementing a modified diet regimen in eligible elderly HD patients. Elderly HD patients who had ingested < 50% of the meals provided and were diagnosed with undernutrition among all elderly patients institutionalized at the special elderly nursing home annexed to Nagasaki Kidney Hospital between June and November 2012. Of the elderly HD patients in the nursing home (n = 27), the study included a total of 7 consecutive patients (male/female, 1/6; mean age, 84.1±6.4 years old; duration of HD, 4.3±3.8 years; geriatric nutritional index [GNRI], 83.5±8.3; normalized protein catabolic ratio [nPCR], 0.78±0.14). The modified diet regimen, which involved reducing food portion sizes and incorporating a liquid diet, led to a significant increase in their dietary intake from 48.1% at baseline to 97.1% of the meals provided 3 months after the start of the modified HD diet regimen. Their GNRI also significantly increased from 83.5±8.3 to 86.1±10.2, and their serum albumin levels significantly increased from 3.2±0.2 g/dL to 3.4±0.4 g/dL, suggesting improvements in their nutritional status. The attempted dietary approach for elderly HD patients was shown to potentially increase their dietary intake and improve their nutritional status without affecting the efficiency of HD being implemented.

    ♦ Accidental falls are common in the hemodialysis (HD) population. The high fall rate has been attributed to a combination of aging, kidney disease-related morbidity, and HD treatment-related hazards. We hypothesized that patients maintained on peritoneal dialysis (PD) would have fewer falls than those on chronic HD. The objective of this study was to compare the falls risk between cohorts of elderly patients maintained on HD and PD, using prospective data from a large academic dialysis facility. ♦ Patients aged 65 years or over on chronic in-hospital HD and PD at the University Health Network were recruited. Patients were followed biweekly, and falls occurring within the first year recorded. Fall risk between the 2 groups was compared using both crude and adjusted Poisson lognormal random effects modeling. ♦ Out of 258 potential patients, 236 were recruited, assessed at baseline, and followed biweekly for falls. Of 74 PD patients, 40 (54%) experienced 86 falls while 76 out of 162 (47%) HD patients experienced a total of 305 falls (crude fall rate 1.25 vs 1.60 respectively, odds ratio [OR] falls in PD patients 0.78, 95% confidence interval [CI] 0.61 - 0.92, p = 0.04). After adjustment for differences in comorbidity, number of medications, and other demographic differences, PD patients were no less likely to experience accidental falls than HD patients (OR 1.63, 95% CI 0.88 - 3.04, p = 0.1). ♦ We conclude that accidental falls are equally common in the PD population and the HD population. These data argue against post-HD hypotension as the sole contributor to the high fall risk in the dialysis population. Copyright © 2016 International Society for Peritoneal Dialysis.

    Hemodialysis vascular access recommendations promote arteriovenous (AV) fistulas first; however, it may not be the best approach for all hemodialysis patients, because likelihood of successful fistula placement, procedure-related and subsequent costs, and patient survival modify the optimal access choice. We performed a decision analysis evaluating AV fistula, AV graft, and central venous catheter (CVC) strategies for patients initiating hemodialysis with a CVC, a scenario occurring in over 70% of United States dialysis patients. A decision tree model was constructed to reflect progression from hemodialysis initiation. Patients were classified into one of three vascular access choices: maintain CVC, attempt fistula, or attempt graft. We explicitly modeled probabilities of primary and secondary patency for each access type, with success modified by age, sex, and diabetes. Access-specific mortality was incorporated using preexisting cohort data, including terms for age, sex, and diabetes. Costs were ascertained from the 2010 USRDS report and Medicare for procedure costs. An AV fistula attempt strategy was found to be superior to AV grafts and CVCs in regard to mortality and cost for the majority of patient characteristic combinations, especially younger men without diabetes. Women with diabetes and elderly men with diabetes had similar outcomes, regardless of access type. Overall, the advantages of an AV fistula attempt strategy lessened considerably among older patients, particularly women with diabetes, reflecting the effect of lower AV fistula success rates and lower life expectancy. These results suggest that vascular access-related outcomes may be optimized by considering individual patient characteristics. Copyright © 2015 by the American Society of Nephrology.

    Returning to society plays an important role in improving the quality of life in maintenance hemodialysis (MHD) patients, and retention of employment is one of the core enablers. The study is to assess the employment status and to determine the variables for unemployment in Chinese MHD patients. Prevalent MHD patients from four dialysis centers in Shanghai China were enrolled. We assessed patients' employment status, current social functioning, hemodialysis modality, annual income and general health condition. Among current unemployed working-age patients, the reasons of quitting jobs and willingness of being reemployed were evaluated. A total of 231 patients were studied, among which 114 patients were unemployed 1 year before hemodialysis. Among 117 employed patients, 16 patients quitted jobs before dialysis inception, while 49 patients quitted jobs at the initiation of HD, and 26 patients followed after a few months' HD. The main reasons for ceasing employment were physical insufficiency, conflict between dialysis and work schedules, lack of support from employers and resistance from family members. Among the 166 patients who were in their working age, 26 patients were employed. The unemployed patients had the characters of elder age, lower education level, higher annual family income, higher female ratio, lower blood flow, lower physical functioning, and social functioning and lower frequency of weekend hemodialysis and HDF/HF. Among the 140 unemployed patients, only 47 patients had the willingness of being reemployed. Their unemployment status was positively associated with elder age ((OR) 3.13, 95% CI, 1.08-9.1), lower education level ((OR) 1.97, 95% CI, 1.05-5.92), and higher family income ((OR) 7.75, 95% CI, 2.49-24.14). Ratio of employment and willingness of being reemployed was low in MHD working-age patients. Lack of social and family's support also hampered patient's returning to society except for the HD treatment quality.

    The scope of this article is to identify sociodemographic and clinical factors associated with the frailty of elderly people with chronic kidney disease on hemodialysis. This involved a correlational, cross-sectional study conducted in a dialysis center in the state of São Paulo. The sample consisted of 60 participants. The Participant Characterization Instrument was used for extracting sociodemographic and clinical data and the Edmonton Frail Scale was used to evaluate the level of frailty. Multivariate logistic regression was used to identify the factors associated with frailty. The mean age of the 60 patients included was 71.1 (± 6.9) years, predominantly male (70%), of which 36.7% were classified as frail. With respect to the factors associated with frailty among the variables of gender, age, self-reported skin color, schooling, monthly per capita income, hemodialysis time, number of associated diseases, falls in the year, hematocrit level, parathyroid hormone and use of calcitriol, it was found that only the monthly per capita income was significantly associated with frailty (OR = 0.44; 95% CI 0.1-0.9; p = 0.04). There was an association between frailty and income, showing that the elderly most at risk of frailty were those with lower income.

    Adherence to treatment in patients on hemodialysis is not a simple process. Strategies to promote adherence will meet the need for improvements in the process of orientation concerning the disease and its pharmacological treatment. To identify compliance with pharmacological treatment of patients on hemodialysis and the main factors related to it we used the Adherence Scale. Observational, descriptive and cross-sectional study. Interviews were conducted to collect socioeconomic, pharmacological data, as well as those regarding self-reported adherence to drug. Out of the 65 participants, 55.4% showed non-compliance. The mean number of drugs used was 4.1 ± 2.5 (self-report) and 6.2 ± 3.0 (prescription). Statistical analysis showed significant differences concerning compliance at different ages (> 60 years are more adherent). A significant proportion of patients have difficulty to comply with treatment and the main factor was forgetfulness. Regarding age, elderly patients are more adherent to treatment. The low level of knowledge about the used drugs may be one of the reasons for the lack of adherence, and the patient's orientation process by a team of multiprofessionals involved in assisting is a strategy to promote adherence.

    Near-death experience (NDE) is a phenomenon that occurs when a person loses consciousness and senses a disconnection from the world around them. Patients on hemodialysis can experience multiple NDEs over their lifetime. An NDE during a hemodialysis session while connected to a hemodialysis machine can present challenges to this patient population and the nurses caring for them. The purpose of this article is to discuss the potential after effects of NDE in patients who experience this phenomenon while connected to a hemodialysis machine and to propose that nurses lead the healthcare team in addressing the after effects of NDE in patients on hemodialysis.

    Diagnosing obesity by body mass index (BMI) may not be reliable in elderly individuals due to the changes in body composition. We aimed to analyze the accuracy of BMI thresholds by World Health Organization (WHO) and Nutrition Screening Initiative (NSI) to diagnose obesity in elderly patients on hemodialysis (HD). Multicenter cross-sectional study. Six dialysis facilities. 169 elderly on chronic HD (70.4 ± 7.1 years; 63.9% men). Total body fat percentage (BF%) was assessed by the sum of skinfold thicknesses and abdominal fat by waist circumference (WC). Both were used as reference to test the specificity and sensitivity of BMI thresholds (WHO: ≥30 kg/m(2); NSI: >27 kg/m(2)). The prevalence of obesity according to NSI-BMI, WHO-BMI, BF%, and WC thresholds were 31%, 13%, 27%, and 29.6% in men, respectively, and 36%, 15%, 13%, and 75% in women. Compared to BF%, the sensitivity of NSI-BMI was moderate (65.5%) for men and high (100%) for women, whereas that of WHO-BMI was low (31%) for men and high (87.5%) for women. Compared with WC, NSI-BMI had good (75%) sensitivity for men and moderate (47.8%) for women, whereas WHO-BMI had moderate (43.8%) sensitivity for men and low (19.6%) for women. The best agreement with BF% was observed for NSI-BMI in men (kappa = 0.46) and for WHO-BMI in women (kappa = 0.80). For WC, the best agreement was for WHO-BMI for men (kappa = 0.63) and NSI-BMI for women (kappa = 0.31). BMI thresholds do not accurately diagnose adiposity in elderly on HD. Therefore, using BMI may lead to misclassifications in this segment population. Copyright © 2016 National Kidney Foundation, Inc. Published by Elsevier Inc. All rights reserved.

    This study aimed to assess whether diminished muscle mass, diminished muscle strength, or both conditions (sarcopenia) are associated with worse nutritional status, poor quality of life (QoL), and hard outcomes, such as hospitalization and mortality, in elderly patients on maintenance hemodialysis (MHD). This is a multicenter observational longitudinal study that included 170 patients on MHD (age 70 ± 7 years, 65% male) from 6 dialysis centers. The European Working Group on Sarcopenia in Older People defines sarcopenia as the presence of both low muscle mass by appendicular skeletal + low muscle function by handgrip strength. This study evaluated the clinical and nutritional status (laboratory, anthropometry, dual-energy X-ray absorptiometry, 7-point subjective global assessment) and QoL (Kidney Disease Quality of Life) at baseline. Hospitalization and mortality were recorded during 36 months. Reduced muscle mass was observed in 64% of the patients, reduced muscle strength in 52%, and sarcopenia in 37%. The group with sarcopenia was older, had a higher proportion of men and showed worse clinical and nutritional conditions when compared with patients without sarcopenia. Although reduced muscle mass was strongly associated with poor nutritional status, low muscle strength was associated with worse QoL domains. In the multivariate Cox analyses adjusted by age, gender, dialysis vintage, and diabetes mellitus, low muscle strength alone and sarcopenia were associated with higher hospitalization, and sarcopenia was a predictor of mortality. In conclusion, in this sample, comprised of elderly patients on MHD, sarcopenia was associated with worse nutritional and clinical conditions and was a predictor of hospitalization and mortality.

    Cast nephropathy is the main cause of acute kidney injury in multiple myeloma and persistent reduction in kidney function strongly affects prognosis. Strategies to rapidly remove nephrotoxic serum-free light chains combined with novel antimyeloma agents have not been evaluated prospectively. To compare the hemodialysis independence rate among patients newly diagnosed with myeloma cast nephropathy treated with hemodialysis using a high-cutoff dialyzer (with very large membrane pores and high permeability to immunoglobulin light chains) or a conventional high-flux dialyzer (with small pores and lower permeability). Randomized clinical trial involving 98 patients with biopsy-proven myeloma cast nephropathy requiring hemodialysis treated at 48 French centers between July 2011 and June 2016; the final date of follow-up was June 29, 2016. Intensive hemodialysis (eight 5-hour sessions over 10 days) with either a high-cutoff dialyzer (46 patients) or a conventional high-flux dialyzer (48 patients). All patients received the same chemotherapy regimen of bortezomib and dexamethasone. Primary end point was hemodialysis independence at 3 months; secondary end points: hemodialysis independence rates at 6 and 12 months, hemodialysis- and chemotherapy-related adverse events, and death. Among 98 randomized patients, 94 (96%) (median age, 68.8 years [interquartile range, 61.2-75.3 years]; 45% women) were included in the modified intent-to-treat analysis. The hemodialysis independence rate at 3 months was 41.3% (n = 19) in the high-cutoff hemodialysis group vs 33.3% (n = 16) in the conventional hemodialysis group (between-group difference, 8.0% [95% CI, -12.0% to 27.9%], P = .42); at 6 months, the rate was 56.5% (n = 26) vs 35.4% (n = 17), respectively (between-group difference, 21.1% [95% CI, 0.9% to 41.3%], P = .04); and at 12 months, the rate was 60.9% (n = 28) vs 37.5% (n = 18) (between-group difference, 23.4% [95% CI, 3.2% to 43.5%], P = .02

    Frequent hemodialysis improves cardiovascular surrogates and quality-of-life indicators, but its effect on survival remains unclear. We used a matched-cohort design to assess relative mortality in daily home hemodialysis and thrice-weekly in-center hemodialysis patients between 2005 and 2008. We matched 1873 home hemodialysis patients with 9365 in-center patients (i.e., 1:5 ratio) selected from the prevalent population in the US Renal Data System database. Matching variables included first date of follow-up, demographic characteristics, and measures of disease severity. The cumulative incidence of death was 19.2% and 21.7% in the home hemodialysis and in-center patients, respectively. In the intention-to-treat analysis, home hemodialysis associated with a 13% lower risk for all-cause mortality than in-center hemodialysis (hazard ratio [HR], 0.87; 95% confidence interval [95% CI], 0.78–0.97). Cause-specific mortality HRs were 0.92 (95% CI, 0.78–1.09) for cardiovascular disease, 1.13 (95% CI, 0.84–1.53) for infection, 0.63 (95% CI, 0.41–0.95) for cachexia/dialysis withdrawal, 1.06 (95% CI, 0.81–1.37) for other specified cause, and 0.59 (95% CI, 0.44–0.79) for unknown cause. Findings were similar using as-treated analyses. We did not detect statistically significant evidence of heterogeneity of treatment effects in subgroup analyses. In summary, these data suggest that relative to thrice-weekly in-center hemodialysis, daily home hemodialysis associates with modest improvements in survival. Continued surveillance should strengthen inference about causes of mortality and determine whether treatment effects are homogeneous throughout the dialysis population. PMID:22362906

    The aim of our study was to evaluate the changes in hemodialysis service, main demographic characteristics of hemodialysis patients in Lithuania during 1996-2005, and their correlation with the number of recipients on the kidney waiting list. During the study period, we annually visited all hemodialysis centers in Lithuania and collected data about all hemodialysis patients. There was a sharp increase in the number of hemodialysis centers (from 17 to 43), hemodialysis stations (from 25 to 100 per million population, P<0.001), hemodialysis patients (from 60 to 312 per million population, P<0.001), and new hemodialysis patients (from 54.3 to 95 per million population, P<0.01). The mean age of hemodialysis patients increased from 47.2+/-16.1 years in 1996 to 58.8+/-15.6 years in 2005 (P<0.001). Hemodialysis population became older. The percentage of patients aged more than 60 years increased from 22.8% to 53.2% (P<0.001) and aged more than 70 years from 5.4% to 24.4% (P<0.001). The frequency of chronic glomerulonephritis as underlying disease of end-stage renal disease decreased from 54.5% in 1996 to 21.1% in 2005 (P<0.001). There was an increase in the percentage of patients in whom end-stage renal disease was caused by diabetic (from 7.1% to 19.2%, P<0.01) and hypertensive nephropathies (from 3.1% to 13.9%, P<0.05) and chronic pyelonephritis (from 11.2% to 17.9%, P<0.01). The percentage of recipients on the kidney waiting list decreased from 71.4% in 1996 to 21.1% in 2005. In summary, during the last 9 years, hemodialysis service in Lithuania significantly expanded. The number of hemodialysis patients was continuously rising with predominance of diabetic, hypertensive, and elderly patients. Diabetic nephropathy, chronic glomerulonephritis, and pyelonephritis were the main underlying diseases of end-stage renal disease in hemodialysis patients in 2005. The percentage of recipients on the kidney waiting list decreased probably because of the rise in the number of

    End stage renal disease has a high burden of disease affecting patient's quality of life and this may dramatically shorten their life expectancy. These patients may be faced with serious stressors which are related to the disease and its treatment. Considering psychosocial problems in hemodialysis patients, we designed this study to evaluate depression, anxiety, social support and to determine temperament, character and correlation between these factors in hemodialysis patients. This was a multicenter cross-sectional study which was done on 218 hemodialysis patients in Isfahan during April-July 2011. Depression, anxiety, social support, temperament and character were evaluated in patients using Hospital Anxiety and Depression Scale (HADS), Persian version of Multidimensional Scale of Perceived Social Support (MSPSS-P) and Temperament and Character Inventory (TCI) questionnaires. 138 (63.3%) subjects were male. Mean age was 58.18 +/- 14.3 years. 95 (43.6%) participants had depression and 94 (43.1%) had anxiety. Family support had the highest score between social support subscales. Family support was significantly correlated with self-directedness (p = 0.012), cooperativeness (p = 0.03), self-transcendence (p = 0.018), reward dependence and friends support (p = 0.036) and cooperativeness and others support (p = 0.049). Physicians should be aware of depression and anxiety in hemodialysis patients. Our results showed that patients had a supportive relation with their family and it could be because of Iranian culture and religious believes. In terms of temperament and character, patients were tolerant, supportive, humble and sociable.

    Cardiovascular disease is a common cause of hospitalization in dialysis patients. Daily hemodialysis improves some parameters of cardiovascular function, but whether it associates with lower hospitalization risk is unclear. Observational cohort study using US Renal Data System data. Medicare-enrolled daily (5 or 6 sessions weekly) home hemodialysis (HHD) patients initiating NxStage System One use from January 1, 2006, through December 31, 2009, and contemporary thrice-weekly in-center hemodialysis patients, matched 5 to 1. Daily HHD or thrice-weekly in-center hemodialysis. All-cause and cause-specific hospital admissions, hospital readmissions, and hospital days assessed from Medicare Part A claims. For 3,480 daily HHD and 17,400 thrice-weekly in-center hemodialysis patients in intention-to-treat analysis, the HR of all-cause admission for daily HHD versus in-center hemodialysis was 1.01 (95%CI, 0.98-1.03). Cause-specific admission HRs were 0.89 (95%CI, 0.86-0.93) for cardiovascular disease, 1.18 (95%CI, 1.13-1.23) for infection, 1.01 (95%CI, 0.93-1.09) for vascular access dysfunction, and 1.02 (95%CI, 0.99-1.06) for other morbidity. Regarding cardiovascular disease, first admission and readmission HRs for daily HHD versus in-center hemodialysis were 0.91 and 0.87, respectively. Regarding infection, first admission and readmission HRs were 1.35 and 1.03, respectively. Protective associations of daily HHD with heart failure and hypertensive disease were most pronounced, as were adverse associations of daily HHD with bacteremia/sepsis, cardiac infection, osteomyelitis, and vascular access infection. Results may be confounded by unmeasured factors, including vascular access type; information about dialysis frequency, duration, and dose was lacking; causes of admission may be misclassified; results may not apply to patients without Medicare coverage. All-cause hospitalization risk was similar in daily HHD and thrice-weekly in-center hemodialysis patients. However

    The question of the targets of dialysis dosing remains controversial since the beginning of the long-term dialysis treatment era. It is still uncertain if higher dialysis dose is better. The aim of our study was to investigate issues of dialysis dose in Lithuania during the period of 1998-2005 and to determine associations between hemodialysis dose and survival of patients on chronic hemodialysis. We analyzed data of all patients who started hemodialysis due to end-stage renal disease in Lithuania between January 1, 1998, and December 31, 2005. The information about hemodialysis frequency, duration, and adequacy (according to Kt/V) was obtained from medical documentation. The overall survival rate was estimated using the Kaplan-Meier method. Survival comparisons were made using the log-rank or Breslow tests. Univariate Cox proportional hazards analysis was used to select variables significantly associated with the risk of death; then these variables were included in multivariate Cox proportional hazards models. During the study period, from 2428 patients who started chronic hemodialysis, 58.5% of patients started hemodialysis three times a week. More than one-third (36.2%) of patients were dialyzed twice weekly, and 5.3% of patients started hemodialysis once weekly. Survival analysis revealed that patients dialyzed less than three times per week survived shorter than patients receiving a higher dialysis dose. Duration of HD session of ≤8 hours per week was an independent risk factor for mortality. A higher mean Kt/V was associated with better survival of patients on chronic hemodialysis. Dialysis frequency and weekly duration of HD sessions were dependent on HD accessibility in Lithuania during the period of 1998-2005. Better survival of patients on chronic hemodialysis was associated with a higher hemodialysis dose.

    There is no any official renal registry in Lithuania, so in order to know the exact demographic statistics of patients on hemodialysis, we started to collect data since 1996. The aim of the study was to estimate the survival rate of hemodialysis patients and its dynamics, to compare survival in different groups of sex, age, primary renal disease, and to compare to survival of dialysis patients in Europe. We analyzed the data of all patients who started hemodialysis in Lithuania between January 1, 1998, and December 31, 2005. The information was obtained from medical documentation. The total survival rate was estimated using the Kaplan-Maier method. During the study period, 2418 patients started hemodialysis (51.7% of males, 48.3% of females). Their mean age at the beginning of treatment was 56.19+/-16.12 years. Death occurred in 792 patients. The main cause of death was cardiovascular events, accounting for 32.3%. The total survival rate of hemodialysis patients in Lithuania at 1 year was 79.97%; at 2 years, 69.18%; at 5 years, 49.97%; at 7 years, 38.3%. Males lived longer than females (log rank P<0.05), but the mean age of females was greater, and survival rate adjusted for age did not differ between the groups. The highest survival rate was in the youngest group (0-19 years old), the lowest - in patients older than 75 years. Diabetic patients lived shorter than nondiabetic patients (log rank P<0.00001). Although patients who start hemodialysis have become older and their survival has been improving, in the 1998-2002 cohort survival was lower as compared to overall survival of patients on dialysis in European countries participating in ERA-EDTA registry. Survival of hemodialysis patients in Lithuania in the 1998-2005 cohort depended on age and primary renal disease and despite aging of population on hemodialysis has been improving.

    Abstract To explore the characteristics and relevant risk factors of periodontal disease (PD) among hemodialysis patients. Uremic patients on maintenance hemodialysis from November 2015 to March 2016 were retrospectively reviewed. Patients were divided into a PD group and a non-PD group. Demographic and laboratory data were collected and analyzed. In all, 136 uremic patients (79 males and 57 females, aged 50.8 ± 15.3 years) on maintenance hemodialysis were included in this study. The incidence of PD increased with age. Hemodialysis patients most likely developed PD if they were male, smokers, or diabetic (P = .009, <.001, and <.001, respectively). Patients brushing their teeth twice daily had significantly less chance of developing PD as compared with those only brushing once daily (P < .001). Hemodialysis patients in the PD group had significantly higher levels of total cholesterol, high-sensitivity C-reactive protein, fasting blood glucose, and peripheral white blood cell counts, compared with the non-PD group (all P < .001). Logistic regression analysis revealed that diabetes, total cholesterol, high-sensitivity C-reactive protein, and peripheral white blood cell count were independent risk factors for developing PD, whereas teeth brushing twice daily and serum calcium were favorable factors for maintenance hemodialysis patients against PD. Identification of risk factors provides a theoretical basis for prevention and improvement of PD among maintenance hemodialysis patients. PMID:28858105

    Protein malnutrition and lowering serum albumin is frequent in hemodialysis patients. A special amino acid formulation has recently been used with favorable effects in elderly people but no data exist in renal patients. To assess the effects of this novel amino acid formulation in stable hemodialysis patients with reduced albumin levels. Thirty stable hemodialysis patients with serum albumin levels <3.5 g/dL, normalized protein nitrogen appearance (nPNA) <1.1 g/kg/d, and body mass index (BMI) >20 kg/m(2) were selected: 15 patients were randomized to oral amino acid supplementation (4 g thrice a day) for 3 months and 15 patients comparable for age, gender, and dialysis durations formed the control group. Biochemistry and bioimpedentiometry parameters were measured at baseline and at the end of treatment. No difference was observed between study group and control group at baseline. At the end of the study period, no change occurred in the studied parameters in the control group, whereas increase in serum albumin (3.1 ± 0.3 vs. 3.6 ± 0.2 g/dL, p < 0.001) and in total proteins (5.7 ± 0.4 vs. 6.4 ± 0.7 g/dL, p < 0.001) occurred in the study group. Hemoglobin rose from 10.7 ± 0.9 to 11.7 ± 0.8 g/dL (p < 0.05) at the same erythropoiesis-stimulating agent (ESA) dosage. C-Reactive protein (CRP) levels decreased in the study group (8.7 ± 7.3 vs. 3.8 ± 3.1 mg/L, p < 0.01). Increase of body weight and of equilibrated protein catabolic rate (ePCR) was observed in the study group. Oral amino acids supplementation was able to improve albumin and total protein in hypoalbuminemia hemodialysis patients. This effect was associated with reduction of CRP levels that is with lowering of pro-inflammatory status and anemia improvement.

    Older adults with chronic disease are more vulnerable to abuse. Early and accurate detection of the elderly abuse phenomenon can help identify health-promoting solutions for the elderly, their family, and society. The purpose of this study was to design and evaluate the psychometric properties of a questionnaire on elderly abuse by family caregivers among older adults on hemodialysis. Qualitative and quantitative research methodologies were used to develop the questionnaire. The item pool was compiled from literature reviews and the Delphi method. The literature reviews comprised 22 studies. The psychometric properties of the questionnaire were verified using face, content, and construct validity, and the reliability was tested using Cronbach's alpha reliability. A 57-item questionnaire was developed after the psychometric evaluation. The Kaiser-Meyer-Olkin index and Bartlett's test of sphericity showed reliable results. Seven components from the exploratory content analysis including psychological misbehavior, authority deprivation, physical misbehavior, financial misbehavior, being abandoned, caring neglect, and emotional misbehavior explained 74.769% of the total variance. Cronbach's alpha was 0.98 and the interclass correlation coefficient was r =0.91 responding to the items twice ( p <0.001), which shows a high level of tool stability. This study developed a questionnaire to assess elderly abuse by family caregivers among older adults on hemodialysis. It is recommended as a mini scale that can be used both in statistical and practical studies, and that is valid and reliable. Nurses or other health care providers can use it in health centers, dialysis centers, or at the house of the patient.

    To investigate the use of manual home blood pressure (BP) monitoring in chronic hemodialysis patients, daily home BPs in 20 patients undergoing chronic hemodialysis were compared with the 44-hour interdialytic ambulatory BPs (ABPs). Each patient recorded home BPs for 2 consecutive weeks with a digital BP monitor three times daily. Prehemodialysis and posthemodialysis BPs were recorded by an oscillometric device in the hemodialysis unit during the same 2 weeks. ABPs were recorded either after the first or second hemodialysis session of the second week during a 44-hour interdialytic period using a Spacelab 90207 ABP monitor. ABP monitoring showed that BP decreased progressively after dialysis, decreased during the first night, and rapidly reached predialysis levels by the next morning. There was no decrease in BP during the second night. There was an excellent correlation between average systolic and diastolic ABP and respective home BPs. Prehemodialysis diastolic BPs were a good reflection of diastolic ABP, but there was more variability in predialysis systolic BP. Posthemodialysis BPs did not correlate with ABP. In patients undergoing chronic hemodialysis, home BPs more reliably reflected the overall BP than incenter BP readings. Predialysis, but not postdialysis, BP should be used as a screening tool to detect hypertension in the hemodialysis unit. Home BP monitoring should be used as a cost-effective means to diagnose occult hypertension in chronic hemodialysis patients.

    Chronic renal insufficiency disease (CRI) leads to uremia in hemodialysis patients and induces a state of immunodepression that results in higher frequencies of infections and diarrhea. Hemodialysis patients resident in the city of Campo Mourão, Paraná, Brazil were analyzed from April 2006 through September 2007 for Blastocystis sp. and other intestinal parasites and for associated diarrhea. Fecal samples from 86 hemodialysis patients and 146 healthy (reference) persons were examined by standard methods for detecting ova, larvae and cysts, which included preservation in 10% formalin and the Kinyoun method. Thirty-three hemodialysis patients (45.1%) and 36 reference individuals (25.7%) were found to be parasitized. The differences in the percentages of parasitism and polyparasitism between the reference group and the chronic renal patients was significant (p= 0.0318 and 0.0019, respectively). Blastocystis sp. (18%-20.1%), Endolimax nana (14%-16.3%), Cryptosporidium sp. (4%-4.7%) and Entamoeba coli (4%-4.7%) were the most frequent protozoa found in the hemodialysis patients. Parasitism was not significantly associated with diarrhea (p=0.9947) or with decreased white blood cell counts (p=0.7046) in these individuals. Because parasitic infections may be an important comorbidity factor in hemodialysis patients, we suggest that parasitological stool examinations, especially for Blastocystis sp. and Cryptosporidium sp., be included in routine medical follow-up examinations of these patients.

    Background and purpose Whether or not uncemented total hip arthroplasty (THA) can achieve durable fixation of implants to bone in patients on chronic hemodialysis is unknown. We analyzed the 2–13-year clinical outcomes of cementless THA in patients with end-stage renal diseases who were maintained on long-term hemodialysis. Patients and methods We reviewed the outcome of 23 consecutive uncemented THAs undertaken between 1993 and 2004, in patients with chronic renal failure who had been on long-term hemodialysis (2–18 years). 1 patient died and 2 patients were lost to follow-up within 2 years, leaving 20 hips (20 patients, median age 66 (38–81) years at the time of THA, 11 females) that were reviewed at median 7 (2–13) years postoperatively. Results Radiographic bone-ingrowth fixation of the components was found in 19 patients. 1 patient had aseptic loosening requiring revision surgery. The median d'Aubigne and Postel score was 10 (8–14) preoperatively and 15 (12–18) at final review. No prosthetic infections were found in any of the patients. Interpretation Uncemented THA shows promising medium-term results in patients receiving long-term hemodialysis. PMID:20175645

    Methicillin-resistant Staphylococcus aureus is a leading cause of death in patients undergoing hemodialysis. However, controversy exists about the optimal dose of vancomycin that will yield the recommended pre-hemodialysis serum concentration of 15-20 mg/L. To develop a data-driven model to optimize the accuracy of maintenance dosing of vancomycin for patients undergoing hemodialysis. A prospective observational cohort study was performed with 164 observations obtained from a convenience sample of 63 patients undergoing hemodialysis. All vancomycin doses were given on the floor after completion of a hemodialysis session. Multivariate linear generalized estimating equation analysis was used to examine independent predictors of pre-hemodialysis serum vancomycin concentration. Pre-hemodialysis serum vancomycin concentration was independently associated with maintenance dose ( B = 0.658, p < 0.001), baseline pre-hemodialysis serum concentration of the drug ( B = 0.492, p < 0.001), and interdialytic interval ( B = -2.133, p < 0.001). According to the best of 4 models that were developed, the maintenance dose of vancomycin required to achieve a pre-hemodialysis serum concentration of 15-20 mg/L, if the baseline serum concentration of the drug was also 15-20 mg/L, was 5.9 mg/kg with interdialytic interval of 48 h and 7.1 mg/kg with interdialytic interval of 72 h. However, if the baseline pre-hemodialysis serum concentration was 10-14.99 mg/L, the required dose increased to 9.2 mg/kg with an interdialytic interval of 48 h and 10.0 mg/kg with an interdialytic interval of 72 h. The maintenance dose of vancomycin varied according to baseline pre-hemodialysis serum concentration of the drug and interdialytic interval. The current practice of targeting a pre-hemodialysis concentration of 15-20 mg/L may be difficult to achieve for the majority of patients undergoing hemodialysis.

    Missed hemodialysis treatments lead to increased morbidity and mortality in the end-stage renal disease population. Little is known about why patients have difficulty attending their scheduled in-center dialysis treatments. Semistructured interviews with 15 adherent and 15 nonadherent hemodialysis patients were conducted to determine patients' attitudes about dialysis, health beliefs and risk perception regarding missed treatments, barriers and facilitators to hemodialysis attendance, and recommendations to improve the system to facilitate dialysis attendance. Average time on dialysis was 2.5 years for the nonadherent group and 7.3 years in the adherent group. In both groups, patients felt that dialysis is life-saving and a necessity. A substantial number of patients in both groups understood that missing hemodialysis treatments is dangerous and several patients could clearly communicate the risk of skipping. The most common barriers to hemodialysis were inadequate or unreliable transportation (mentioned in both groups) and a lack of motivation to get to dialysis or that dialysis is not a priority (typically mentioned by the nonadherent group). Facilitators to hemodialysis attendance included explanations from the health care team regarding the risk of skipping and relationships with other dialysis patients. Patient recommendations to improve dialysis attendance included continued education about the risk of poor attendance and more accessible transportation. Patients did not feel that home dialysis would improve adherence. Hemodialysis patients must adhere to a complex and burdensome regimen. Through the elucidation of barriers and facilitators to hemodialysis attendance and through specific patient recommendations, at least three interventions may be further investigated to improve hemodialysis attendance: Improvement of the transportation system, education and supportive encouragement from the health care team, and peer support mentorship. © 2014 International

    To describe hypersensitivity reactions in patients receiving maintenance hemodialysis. PubMed search of articles published during the past 30 years with an emphasis on publications in the past decade. Case reports and review articles describing hypersensitivity reactions in the context of hemodialysis. Pharmacologic agents are the most common identifiable cause of hypersensitivity reactions in patients receiving hemodialysis. These include iron, erythropoietin, and heparin, which can cause anaphylactic or pseudoallergic reactions, and topical antibiotics and anesthetics, which lead to delayed-type hypersensitivity reactions. Many hypersensitivity reactions are triggered by complement activation and increased bradykinin resulting from contact system activation, especially in the context of angiotensin-converting enzyme inhibitor use. Several alternative pharmacologic preparations and dialyzer membranes are available, such that once an etiology for the reaction is established, recurrences can be prevented without affecting the quality of care provided to patients. Although hypersensitivity reactions are uncommon in patients receiving hemodialysis, they can be life-threatening. Moreover, considering the large prevalence of the end-stage renal disease population, the implications of such reactions are enormous. Most reactions are pseudoallergic and not mediated by immunoglobulin E. The multiplicity of potential exposures and the complexity of the environment to which patients on dialysis are exposed make it challenging to identify the precise cause of these reactions. Great diligence is needed to investigate hypersensitivity reactions to avoid recurrence in this high-risk population. Copyright © 2017 American College of Allergy, Asthma & Immunology.

    To analyze the hospital outcomes of patients, with chronic renal insufficiency in the hemodialysis, submitted to OPCAB. Fifty-one patients with chronic renal insufficiency were submitted to OPCAB. Hemodialysis was performed on the day before and the day after the operation. Myocardial revascularization was performed using LIMA's suture and suction stabilization. Fifty-one patients, with an average of 61.28+/-11.09 years, were analyzed. Thirty patients (58.8%) were female. The predominant functional class was IV in 21 (41.1%) of the patients. The left ventricle ejection fraction was dire in 21 (41.1%) patients. The mean EUROSCORE of this series was 7.65+/-3.83 and the mean number of distal anastomosis was 3.1+/-0.78 per patient. The average time of mechanical ventilation was 3.78+/-4.35 hours and the mean ICU stay was 41.9+/-13.8 hours, while the average hospitalization was 6.5+/-1.31 days. In respect to complications, nine (17.6%) of the patients developed atrial fibrilation, and one (1.9%) patient presented with a case of ischemic stroke but had a good recovery during hospitalization. There were no deaths in this series. Chronic renal patients submitted to hemodialysis were always a high risk population for myocardial revascularization. In this series, the absence of extracorporeal circulation appeared to be safe and efficient in this special subgroup of patients. The operations were performed with low indices of complications, absence of deaths and relatively low stays in the ICU and in hospital.

    Carnitine is a small molecule widely present in all cells from prokaryotic to eukaryotic. It is an important element in β-oxidation of fatty acids. Carnitine is a scavenger of oxygen free radicals in mammalian tissues. Lack of carnitine in a hemodialysis patient can lead to carnitine deficiency. Oxidation of fatty acids and lipid metabolism are severly affected by carnitine deficiency. Oxidative stress is defined as imbalance between formation of free radicals and antioxidative defense mechanisms. It has been proposed to play a role in many disease states. In hemodialysis patients multiple factors can lead to a a high susceptibility to oxidative stress. The aim of this study was to determine hemodialysis effectiveness on the change rate of serum L-carnitine and lipid peroxidation. 27 patients with chronic renal failure (24-80 yrs) who undergo hemodialysis for 6-12 months were selected (M= 17, F= 10). Malondialdehyde (MDA), as an indicator of lipid peroxidation was measured colorimetrically with a standard thiobarbituric acid (TBA) method. L-carnitine was measured with enzymatic UV method (ROCHE, Spectronic Genesis 2, 340 nm). The weight mean of L-carnitine before and after hemodialysis was 7.67±3.6 mg/l and 2.07±1.6 mg/l, respectively (P<0.001). The weight mean of pre-hemodialysis MDA was 4.17±1.24 µmol/l, following hemodialysis -4.98±1.2 µmol/l (P<0.001). Results showed that 55.6% of patients suffered from carnitine defciency. Serum carnitine was found to be decreased markedly after hemodialysis (P<0.001). Our findings indicated that oxidative stress in these patients is further exacerbated by hemodialysis, as evidenced by increased lipid peroxidation. The relationship between serum L-carnitine and MDA before and after hemodialysis was observed (r=0.82; p<0.001; r=0.75; p<0.001). PMID:27683353

    Vitamin D deficiency is prevalent in the general elderly population, and is related to an increased risk of osteoporosis, fractures, and cardiovascular calcification. Only limited data and no guidelines are available on vitamin D deficiency in hemodialysis patients. We aimed to assess the frequency of, and factors associated with, 25(OH) vitamin D deficiency in hemodialysis patients in a French dialysis center. In March 2006, we studied all prevalent hemodialysis patients who had not received native vitamin D supplements in the recent past. According to the Kidney Disease Outcomes and Quality Initiative guidelines, patients were assigned to the following 3 groups: group 1, with a sufficient vitamin D serum level (>75 nmol/L); group 2, with an insufficient level (25 to 75 nmol/L); and group 3, with severe deficiency (<25 nmol/L). Patients' characteristics and biochemical findings were compared between patients of groups 1 and 3. Of 253 patients, 11% patients were in group 1; 47% were in group 2; and 42% were in group 3. The proportions of female and diabetes patients were 42% and 34%, respectively. The mean (+/- SD) age of all patients was 66.7 +/- 14 years, and the mean duration of dialysis was 62 +/- 74 months, with a mean schedule of 3 x 6.5 hours and administration of a 1.5 mmol/L calcium dialysate. Concomitant treatment included alfacalcidol (66% of patients) and sevelamer (34% of patients) as a standard phosphate binder. Group 3 patients had a lower dialysis vintage (53 +/- 66 vs. 73 +/- 85 months, P < .05), a higher number of diabetes patients (45% vs. 21%, P < .05), a higher number of female patients (53% vs. 28%, P < .05), and a higher level of intact parathyroid hormone (260 +/- 227 vs. 213 +/- 153 pg/mL, P < .05) than group 1 patients. No relationship was found between vitamin D storage levels and bone markers, serum calcium, phosphorus, albumin, body mass index, normalized protein catabolic rate, radiologic vascular calcification score, and hip bone

    The present study was designed to analyze the serum levels of aspartate and alanine aminotransferases, gamma-glutamyl transferase, and the hematocrit in patients with chronic kidney disease who were undergoing peritoneal dialysis or hemodialysis. Twenty patients on peritoneal dialysis and 40 on hemodialysis were assessed, and the patients were matched according to the length of time that they had been on dialysis. Blood samples were collected (both before and after the session for those on hemodialysis) to measure the enzymes and the hematocrit. In the samples from the patients who were undergoing peritoneal dialysis, the aspartate and alanine aminotransferase levels were slightly higher compared with the samples collected from the patients before the hemodialysis session and slightly lower compared with the samples collected after the hemodialysis session. The levels of gamma-glutamyl transferase in the hemodialysis patients were slightly higher than the levels in the patients who were undergoing peritoneal dialysis. In addition, the levels of aminotransferases and gamma-glutamyl transferase that were collected before the hemodialysis session were significantly lower than the values collected after the session. The hematocrit levels were significantly lower in the patients who were on peritoneal dialysis compared with the patients on hemodialysis (both before and after the hemodialysis session), and the levels were also significantly lower before hemodialysis compared with after hemodialysis. The aminotransferase levels in the patients who were undergoing peritoneal dialysis were slightly higher compared with the samples collected before the hemodialysis session, whereas the aminotransferase levels were slightly lower compared with the samples collected after the session. The hematocrits and the aminotransferase and gamma-glutamyl transferase levels of the samples collected after the hemodialysis session were significantly higher than the samples collected before

    Patients with chronic kidney disease, have a higher risk for psychological distress such as anxiety, depression and cognitive decline. Combination of Hemodialysis (HD)/hemoperfusion (HP) regularly able to eliminate uremic toxin with mild-to-large molecular weight better. HD/HP can remove metabolites, toxin, and pathogenic factors and regulate the water, electrolyte and acid-base balance to improve the quality of patient’s sleep and appetite also reduces itching of the skin, which in turn improve the quality and life expectancy. This research was a cross sectional research with a pre-experimental design conducted from July to September 2015 with 17 regular hemodialysis patients as samples. Inclusion criteria were regular hemodialysis patients and willingly participated in the research. The assessmentwas conducted using BDI to assess depression. To obtained the results, data were analyzed using T-Test and showed that that the average BDI score before the combination of HD/HP 18.59±9 to 8.18±2.83 after the combination (p<0.001). In conclusion, combination HD/HP can lower depression scores in patients with regular HD.

    Infections cause significant morbidity and mortality in patients undergoing hemodialysis. Bloodstream infections (BSIs) are particularly problematic, accounting for a substantial number of hospitalizations in these patients. Hospitalizations for BSI and other vascular access infections appear to have increased dramatically in hemodialysis patients since 1993. These infections frequently are related to central venous catheter (CVC) use for dialysis access. Regional initiatives that have shown successful decreases in catheter-related BSIs in hospitalized patients have generated interest in replicating this success in outpatient hemodialysis populations. Several interventions have been effective in preventing BSIs in the hemodialysis setting. Avoiding the use of CVCs in favor of access types with lower associated BSI risk is among the most important. When CVCs are used, adherence to evidence-based catheter insertion and maintenance practices can positively influence BSI rates. In addition, facility-level surveillance to detect BSIs and stimulate examination of vascular access use and care practices is essential to a comprehensive approach to prevention. This article describes the current epidemiology of BSIs in hemodialysis patients and effective prevention strategies to decrease the incidence of these devastating infections.

    This study had 2 objectives: (1) to describe the epidemiology of catheter-related bloodstream infections (CRBSI) in patients with end-stage renal disease (ESRD) who have no access to scheduled dialysis and (2) to evaluate whether a positive culture of the heparin-lock solution is associated with subsequent development of bacteremia. Retrospective observational cohort design for objective 1; and prospective cohort design for objective 2. The study was conducted in a 770-bed public academic tertiary hospital in Dallas, Texas. The participants were patients with ESRD undergoing scheduled or emergent hemodialysis. We reviewed the records of 147 patients who received hemodialysis between January 2011 and May 2011 and evaluated the rate of CRBSI in the previous 5 years. For the prospective study, we cultured the catheter heparin-lock solution in 62 consecutive patients between June 2012 and August 2012 and evaluated the incidence of CRBSI at 6 months. Of the 147 patients on emergent hemodialysis, 125 had a tunneled catheter, with a CRBSI rate of 2.61 per 1,000 catheter days. The predominant organisms were Gram-negative rods (GNR). In the prospective study, we found that the dialysis catheter was colonized more frequently in patients on emergent hemodialysis than in those on scheduled hemodialysis. Colonization with GNR or Staphylococcus aureus was associated with subsequent CRBSI at 6 months follow-up. Patients undergoing emergent hemodialysis via tunneled catheter are predisposed to Gram-negative CRBSI. Culturing the heparin-lock solution may predict subsequent episodes of CRBSI if it shows colonization with GNR or Staphylococcus aureus. Prevention approaches in this population need to be studied further.

    Objective. To identify the relationship between microinflammation, oxidative stress, and carotid arterial stiffness in hemodialysis patients. Methods. The CAS β and PWV obtained by ultrasound technology were used to assess carotid arterial stiffness. We divided the patients into either the CAS group or the non-CAS group based on the presence or absence of CAS. The parameters of ALB, Ca, P, TC, HDL, LDL, TG, glucose, creatinine, and hs-CRP levels were routinely tested in both groups of patients. The levels of TNF-α, IL-6, and 8-isoprostane F2α were measured by ELISA. Results. A total of 42 patients were enrolled in the CAS group and 20 patients were enrolled in the non-CAS group. No significant differences between the CAS group and the non-CAS group were observed with respect to age, dialysis duration, DBP, BUN, Cr, TC, TG, HDL, LDL, and Hb. However, SBP , pulse pressure, and 8-isoprostane levels of the CAS group were higher than those of the non-CAS group. The hs-CRP, TNF-α, and IL-6 levels were elevated in both groups but showed no significant differences. Conclusions. Maintenance of hemodialysis patients exhibits a microinflammatory state that may lead to atherosclerosis. The roles of hypertension and oxidative stress may be more important. PMID:24187620

    We sought to describe the perspectives and experiences of chronic hemodialysis (CHD) patients regarding self-care and adherence to fluid restrictions. Semistructured focus groups. Two outpatient hemodialysis centers. Nineteen patients on chronic hemodialysis. Patients were asked a series of open-ended questions to encourage discussion about the management of fluid restriction within the broad categories of general knowledge, knowledge sources or barriers, beliefs and attitudes, self-efficacy, emotion, and self-care skills. We analyzed session transcripts using the theoretical framework of content analysis to identify themes generated by the patients. Patients discussed both facilitators and barriers to fluid restriction, which we categorized into six themes: knowledge, self-assessment, psychological factors, social, physical, and environmental. Psychological factors were the most common barriers to fluid restriction adherence, predominantly involving lack of motivation. Knowledge was the most discussed facilitator with accurate self-assessment, positive psychological factors, and supportive social contacts also playing a role. Dialysis providers were most commonly described as the source of dialysis information (54%), but learning through personal experience was also frequently noted (28%). Interventions to improve fluid restriction adherence of chronic hemodialysis patients should target motivational issues, assess and improve patient knowledge, augment social support, and facilitate accurate self-assessment of fluid status.

    Fatigue is a common and debilitating symptom for adult patients with end stage renal disease on hemodialysis and has been associated with decreased survival and quality of life. Patients on hemodialysis must find ways to manage their fatigue and mitigate its effects on their lives. Currently, there is no description of the experience of fatigue for patients on hemodialysis living in the U.S., nor is there any description of the ways in which they manage their fatigue. The purpose of this qualitative descriptive work was to describe the experience and self-management of fatigue. Several themes were identified which included: the nature of fatigue, management of fatigue, consequences of fatigue, and factors associated with fatigue. This information will be valuable to nephrology nurses as they continue to care for and educate patients on hemodialysis. PMID:23767335

    Sleep disorders are considered as one of the most important problems in hemodialysis patients, making their everyday life a serious hazard. Sleep quality of hemodialysis patients and consequences of sleep disorders on other aspects of health such as spiritual well-being are important issues. This study examined the relationship between spiritual well-being and quality of sleep in hemodialysis patients in Isfahan, Iran. This study was a correlation research, carried out on 190 hemodialysis patients. Data collection Questionnaires included demographic forms, Pittsburgh sleep quality index (PSQI), and Ellison and Paloutzian spiritual well-being scale. Data were analyzed using descriptive and inferential statistics (Pearson correlation and linear regression analysis) at P < 0.05 significance level, by SPSS software version 18. Of 190 study participants, 163 (85.78%) with scores more than five index had sleep disturbances and 27 (14.12%) had no sleep disturbance; 3 (1.52%) had mild, 163 (85.78%) moderate, and 24 (12.30%) good spiritual health conditions. Pearson correlation test showed significant relationship between the sleep quality items of Pittsburg and spiritual well-being (P < 0.04, r = 0.149). Through the regression analyses of spiritual health, family, education, financial status, marital status, occupation, and use of sleep medication, the predictive power of these variables was found 0.417% and prediction of spiritual well-being was more than others (ß = 0.209). Considering bed as one of the most vital physical, mental, and emotional needs, it is very important in mental and spiritual well-being of hemodialysis patients as an influencing factor in mental relaxation and reducing disease tensions. Paying attention to sleep quality and spiritual well-being components of hemodialysis patients in formulating and promoting healthcare programs is recommended.

    Maintenance hemodialysis (MHD) patients suffer from a number of co-morbidities including declines in muscle mass and physical function. Beta-hydroxy-beta-methylbutyrate (HMB) is a metabolite of the amino acid leucine that has been shown to improve lean mass and physical function in elderly and clinical populations, but had not been studied in MHD patients. The purpose of this study was to investigate the efficacy of HMB in this population. We performed a double-blind, placebo-controlled, randomized trial to assess the effects of daily HMB supplementation on co-morbidities in MHD patients. MHD patients were recruited and assigned to either daily supplementation with HMB (n = 16) or placebo (n = 17) for 6 months. Measurements of body composition, bone density, strength, physical function, fall risk, quality of life, and blood parameters were measured at baseline and 6 months. Blood was drawn at baseline, 3, and 6 months to measure compliance. No significant effects of HMB on body composition, bone density, strength, physical function, fall risk, quality of life, or blood parameters were observed. On analysis of plasma HMB concentrations, 5 of 16 patients (31%) in the HMB group were found to be noncompliant at 3 or 6 months. Therefore, we performed a per-protocol analysis with compliant participants only and observed no significant differences in our outcomes of interest. These results do not support the efficacy of HMB to attenuate co-morbid conditions in MHD patients. Moreover, this highlights the need for future interventions targeted at reducing pill burden and improving pill compliance in this population. © 2016 International Society for Hemodialysis.

    Contemporary comparisons of mortality in matched hemodialysis and peritoneal dialysis patients are lacking. We aimed to compare survival of incident hemodialysis and peritoneal dialysis patients by intention-to-treat analysis in a matched-pair cohort and in subsets defined by age, cardiovascular disease, and diabetes. We matched 6337 patient pairs from a retrospective cohort of 98,875 adults who initiated dialysis in 2003 in the United States. In the primary intention-to-treat analysis of survival from day 0, cumulative survival was higher for peritoneal dialysis patients than for hemodialysis patients (hazard ratio 0.92; 95% CI 0.86 to 1.00, P = 0.04). Cumulative survival probabilities for peritoneal dialysis versus hemodialysis were 85.8% versus 80.7% (P < 0.01), 71.1% versus 68.0% (P < 0.01), 58.1% versus 56.7% (P = 0.25), and 48.4% versus 47.3% (P = 0.50) at 12, 24, 36, and 48 months, respectively. Peritoneal dialysis was associated with improved survival compared with hemodialysis among subgroups with age <65 years, no cardiovascular disease, and no diabetes. In a sensitivity analysis of survival from 90 days after initiation, we did not detect a difference in survival between modalities overall (hazard ratio 1.05; 95% CI 0.96 to 1.16), but hemodialysis was associated with improved survival among subgroups with cardiovascular disease and diabetes. In conclusion, despite hazard ratio heterogeneity across patient subgroups and nonconstant hazard ratios during the follow-up period, the overall intention-to-treat mortality risk after dialysis initiation was 8% lower for peritoneal dialysis than for matched hemodialysis patients. These data suggest that increased use of peritoneal dialysis may benefit incident ESRD patients. PMID:20133483

    A 75-year-old male who was undergoing chronic hemodialysis developed abrupt-onset pitting edema and pain in the dorsum of both hands and feet. Biochemical analysis disclosed increased C-reactive protein, and negative rheumatoid factor and antinuclear antibody. Radiological examination showed no bony erosion. Computed tomography and gallium scintigraphy revealed no active infection or neoplasms. The clinical diagnosis was remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome. The pitting edema and inflammatory response quickly subsided after low-dose prednisolone therapy. This case demonstrates that RS3PE syndrome could be a differential diagnosis in elderly patients undergoing dialysis who develop pitting edema and joint pain. PMID:22431931

    Hepatitis C virus (HCV) infection is the most common chronic blood-borne infection in the United States; the prevalence in maintenance hemodialysis patients substantially exceeds that in the general population. In hemodialysis patients, HCV infection has been associated with increased occurrence of cirrhosis and hepatocellular carcinoma and increased mortality. Injection drug use and receipt of blood transfusions before 1992 has accounted for most prevalent HCV infections in the United States. However, HCV transmission among patients undergoing hemodialysis has been documented frequently. Outbreak investigations have implicated lapses in infection control practices as the cause of HCV infections. Preventing these infections is an emerging priority for renal care providers, public health agencies, and regulators. Adherence to recommended infection control practices is effective in preventing HCV transmission in hemodialysis facilities. In addition, adoption of routine screening to facilitate the detection of incident HCV infections and hemodialysis-related transmission is an essential component of patient safety and infection prevention efforts. This article describes the current epidemiology of HCV infection in US maintenance hemodialysis patients and prevention practices to decrease its incidence and transmission.

    Patients undergoing conventional maintenance hemodialysis typically receive three sessions per week, each lasting 2.5–5.5 hours. Recently, the use of more intensive hemodialysis (>5.5 hours, three to seven times per week) has increased, but the effects of these regimens on survival are uncertain. We conducted a retrospective cohort study to examine whether intensive hemodialysis associates with better survival than conventional hemodialysis. We identified 420 patients in the International Quotidian Dialysis Registry who received intensive home hemodialysis in France, the United States, and Canada between January 2000 and August 2010. We matched 338 of these patients to 1388 patients in the Dialysis Outcomes and Practice Patterns Study who received in-center conventional hemodialysis during the same time period by country, ESRD duration, and propensity score. The intensive hemodialysis group received a mean (SD) 4.8 (1.1) sessions per week with a mean treatment time of 7.4 (0.87) hours per session; the conventional group received three sessions per week with a mean treatment time of 3.9 (0.32) hours per session. During 3008 patient-years of follow-up, 45 (13%) of 338 patients receiving intensive hemodialysis died compared with 293 (21%) of 1388 patients receiving conventional hemodialysis (6.1 versus 10.5 deaths per 100 person-years; hazard ratio, 0.55 [95% confidence interval, 0.34–0.87]). The strength and direction of the observed association between intensive hemodialysis and improved survival were consistent across all prespecified subgroups and sensitivity analyses. In conclusion, there is a strong association between intensive home hemodialysis and improved survival, but whether this relationship is causal remains unknown. PMID:22362910

    Acute kidney injury (AKI) is associated with increased morbidity and mortality. Mortality in end-stage renal disease (ESRD) patients is highest during the first year of dialysis. The impact of pre-ESRD AKI events on long-term outcomes in incident ESRD patients remains unknown. We evaluated a retrospective cohort of 47,341 incident hemodialysis patients from the United States Renal Data System with linked Medicare data for at least 2 years prior to hemodialysis initiation. We examined the impact of pre-ESRD AKI events in the 2-year pre-ESRD period on the type of vascular access used at hemodialysis initiation (central venous catheter (CVC) versus arteriovenous access), and 1-year all-cause mortality after initiating hemodialysis. The mean age was 72 ± 11 years. Of the study cohort, 18% initiated hemodialysis with arteriovenous access, and 54% of patients had at least one pre-ESRD AKI event. One-year, all-cause mortality was 32%. Compared to 75% for patients without a pre-ESRD AKI event, 89% of patients with a pre-ESRD AKI event initiated hemodialysis with CVC than arteriovenous access (p < 0.001). A pre-ESRD AKI event was associated with lower adjusted odds of starting hemodialysis with an arteriovenous access (OR 0.47; 95% CI 0.44-0.50, p < 0.001), and higher adjusted odds of 1-year mortality (OR 1.36; 95% CI 1.30-1.42, p < 0.001).

    The aim of this study was to investigate the serum concentration of adipokines, such as leptin, adiponectin, and resistin, and assess its relation to nutritional and inflammatory parameters in both overweight and normal weight patients on maintenance hemodialysis. A total of 36 hemodialysis patients (27 M, 9 F; mean age 55.3 +/- 12 yr.) were examined and 23 additional healthy volunteers were recruited as the control group. The concentrations of leptin, leptin receptor, adiponectin, resistin, IL-6, TNFa and CRP were measured by ELISA. Assessment of nutritional status was determined by the levels of albumin, BMI, percentage of body fat (%F), lean body mass (LBM), and Subjective Global Assessment Score (SGA). According to the SGA 7-points score and the albumin level, 20 patients were of good nutritional status (6-7 points), while 16 patients were mildly malnourished (4-5 points). The concentrations of CRP, resistin, adiponectin, and TNFa were statistically higher in hemodialysis patients than in the control group (p pound 0.05). The adiponectin level was inversely correlated with %F (R Spearman=-0.3; p pound 0.05). The level of leptin was positively correlated with %F as well as with BMI and SGA scores (R Spearman=0.4; p pound 0.05). Although there was no significant difference in the nutritional status between the nonoverweight (BMI 18.5-24.99) and overweight (BMI (3)25.0) groups of patients, in the nonoverweight group there were 12 patients (54.5%) with signs of mild malnutrition compared to 4 malnourished patients (28.5%) in the overweight group. Nonoverweight patients presented significantly lower leptin concentration (12.7 vs 27.8 ug/l) and higher adiponectin level (38.9 vs 32.5 ng/ml) when compared to overweight patients. The levels of IL-6 and TNFa were higher in the nonoverweight group of patients. Overweight patients also had shorter durations of stay in the hemodialysis program (30.5 vs. 87.6 months). The results of our study indicate that lean hemodialysis

    The presence or absence of hypothyroidism was assessed in 152 consecutive Japanese patients with end-stage renal disease on hemodialysis. Eight patients who had undergone treatment for thyroid disease before starting hemodialysis therapy, and 3 patients with amyloidosis due to rheumatoid arthritis were excluded. Of the remaining 141 hemodialysis patients, 14 (9.9%) (9 males and 5 females, aged 69.1 A+/- 8.8 years with a mean duration of hemodialysis of 69 A+/- 51 months) were in a hypothyroid state, defined as a thyroid-stimulating hormone (TSH) level > 5 mU/l. Antithyroid peroxidase antibodies were positive in only 1 of the 14 patients, while antithyroglobulin antibodies were negative in all of these patients. After iodide restriction, the serum TSH level decreased in all the patients from a mean of 16.49 A+/- 22.80 to 4.44 A+/- 3.35 mU/l after 1 month, 4.25 A+/- 2.24 mU/l after 2 months and 3.97 A+/- 2.22 mU/l after 3 months. The 3 months of iodide restriction were also associated with decreases in systolic blood pressure (142 A+/- 19 to 125 A+/- 16 mmHg, p < 0.05), diastolic blood pressure (79 A+/- 13 to 72 A+/- 9 mmHg, p < 0.05) and thyroid gland volume estimated by ultrasonography (13.7 A+/- 6.3 to 11.6 A+/- 5.2 ml, p < 0.05). A high prevalence of reversible primary hypothyroidism was found in end-stage renal disease patients on hemodialysis. Retention of excess iodide may be the mechanism responsible for reversible hypothyroidism rather than immunological perturbations. It is, therefore, recommended to attempt iodide restriction before starting l-thyroxine replacement therapy.

    Chronic renal failure exposes patients to the risk of several complications, which will affect every aspect of patient's life, and eventually his hope. This study aims to determine the effect of stress management group training on hope in hemodialysis patients. In this quasi-experimental single-blind study, 50 patients with renal failure undergoing hemodialysis at Motahari Hospital in Jahrom were randomly divided into stress management training and control groups. Sampling was purposive, and patients in stress management training group received 60-minute in-person training by the researcher (in groups of 5 to 8 patients) before dialysis, over 5 sessions, lasting 8 weeks, and a researcher-made training booklet was made available to them in the first session. Patients in the control group received routine training given to all patients in hemodialysis department. Patients' hope was recorded before and after intervention. Data collection tools included demographic details form, checklist of problems of hemodialysis patients and Miller hope scale (MHS). Data were analyzed in SPSS-18, using Chi-square, one-way analysis of variance, and paired t-test. Fifty patients were studied in two groups of 25 each. No significant difference was observed between the two groups in terms of age, gender, or hope before intervention. After 8 weeks of training, hope reduced from 95.92±12.63 to 91.16±11.06 (P=0.404) in the control group, and increased from 97.24±11.16 to 170.96±7.99 (P=0.001) in the stress management training group. Significant differences were observed between the two groups in hope scores after the intervention. Stress management training by nurses significantly increased hope in hemodialysis patients. This low cost intervention can be used to improve hope in hemodialysis patients.

    Sudden cardiac death (SCD) is the leading cause of death in hemodialysis patients, accounting for death in up to one-quarter of this population. Unlike in the general population, coronary artery disease and heart failure often are not the underlying pathologic processes for SCD; accordingly, current risk stratification tools are inadequate when assessing these patients. Factors assuming greater importance in hemodialysis patients may include left ventricular hypertrophy, electrolyte shift, and vascular calcification. Knowledge regarding SCD in hemodialysis patients is insufficient, in part reflecting the lack of an agreed-on definition of SCD in this population, although epidemiologic studies suggest the most common times for SCD to occur are toward the end of the long 72-hour weekend interval between dialysis sessions and in the 12 hours immediately after hemodialysis. Accordingly, it is hypothesized that the dialysis procedure itself may have important implications for SCD. Supporting this is recognition that hemodialysis is associated with both ventricular arrhythmias and dynamic electrocardiographic changes. Importantly, echocardiography and electrocardiography may show changes that are modifiable by alterations to dialysis prescription. The most effective preventative strategy in the general population, implanted cardioverter-defibrillator devices, are less effective in the presence of chronic kidney disease and have not been studied adequately in dialysis patients. Last, many dialysis patients experience SCD despite not fulfilling current criteria for implantation, making appropriate allocation of defibrillators uncertain.

    Hepatitis C virus (HCV) infection is associated with an increase in proinflammatory cytokine levels. Similar changes are seen in maintenance hemodialysis patients with malnutrition-inflammation-cachexia syndrome (MICS), which is associated with poor clinical outcomes in this population. We hypothesized that HCV transcription-mediated amplification (TMA), a sensitive qualitative molecular test for HCV RNA, may identify maintenance hemodialysis patients with HCV infection not detected by means of antibody enzyme immunoassay (EIA), particularly in those with MICS. We evaluated HCV status in 314 maintenance hemodialysis patients by using HCV antibody EIA (version 2.0; Abbott Laboratories, Abbott Park, IL) and HCV TMA (Bayer Diagnostics Laboratories, Berkeley, CA). Twenty-five patients (8%) were EIA positive (EIA+)/TMA+; 4 patients (1%), EIA+/TMA negative (TMA-), and 22 patients (7%), EIA-/TMA+. In the 47 TMA+ patients, the sensitivity of EIA for HCV infection was only 53%. TMA+ patients had lower albumin levels and higher tumor necrosis factor alpha and serum glutamic oxaloacetic transaminase levels than TMA- patients. EIA+/TMA+ patients were more likely than EIA-/TMA+ or EIA-/TMA- patients to have hypoalbuminemia and higher iron and transaminase levels. Of all TMA+ patients, EIA- patients were more likely to have diabetes, be on dialysis therapy longer, and have lower liver enzyme levels and higher proinflammatory cytokine levels, including tumor necrosis factor alpha and interleukin 6. Maintenance hemodialysis patients infected with HCV according to TMA have clinical features suggestive of MICS. In this population, HCV EIA appears to have a low sensitivity for the identification of HCV infection, which may be caused by the confounding effect of MICS or other demographic or clinical factors. These apparently false-negative HCV antibody test results are seen in persons with a longer time on hemodialysis therapy, mirroring observations in other populations with serious

    Background and Objectives: Renal failure patients show significant impairment on measures of attention and memory, and consistently perform significantly better on neuropsychological measures of memory and attention, approximately 24 hours after hemodialysis treatment. The objectives are to determine the cognitive dysfunction in patients with renal failure requiring hemodialysis. Materials and Methods: A total of 60 subjects comprising of 30 renal failure patients and 30 controls were recruited. The sample was matched for age, sex, and socioeconomic status. The tools used were the Standardized Mini-Mental State Examination and the Brief Cognitive Rating Scale. Results: The patients showed high cognitive dysfunction in the pre-dialysis group, in all the five dimensions (concentration, recent memory, past memory, orientation and functioning, and self-care), and the least in the 24-hour post dialysis group. This difference was found to be statistically significant (P=0.001). Conclusion: Patients with renal failure exhibited pronounced cognitive impairment and these functions significantly improved after the introduction of hemodialysis. PMID:23439613

    Over the past 20 years, the role of psychological and social factors, including the physician-patient working alliance, have emerged as integral components of medical care for patients with a myriad of health conditions. The current study examines a model comprised of psychological-interpersonal factors and the extent to which it explains patient satisfaction with and adherence to hemodialysis treatment. One hundred and seven adults with end-stage renal disease who were receiving regular outpatient hemodialysis participated in the study. Path analyses show that the physician-patient working alliance indirectly predicts patient adherence through patient satisfaction and patients' outcome expectations. The working alliance directly predicts patients' quality of life. It is concluded that consistent with previous research, the physician-patient working alliance is a significant factor in predicting key patient behaviors in medical care.

    The (pro)renin receptor [(P)RR] is cleaved by furin to generate soluble (P)RR [s(P)RR], which reflects the status of the tissue renin-angiotensin system. Hemodialysis patients have advanced atherosclerosis. The aim of this study was to investigate the relationships between serum s(P)RR levels and background factors, including indices of atherosclerosis, in hemodialysis patients. Serum s(P)RR levels were measured in hemodialysis patients and clearance of s(P)RR through the membrane of the dialyzer was examined. Furthermore, relationships between serum s(P)RR levels and background factors were assessed. Serum s(P)RR levels were significantly higher in hemodialysis patients (30.4 ± 6.1 ng/ml, n = 258) than those in subjects with normal renal function (21.4 ± 6.2 ng/ml, n = 39, P < 0.0001). Clearance of s(P)RR and creatinine were 56.9 ± 33.5 and 147.6 ± 9.50 ml/min, respectively. Serum s(P)RR levels were significantly higher in those with ankle-brachial index (ABI) of < 0.9, an indicator of severe atherosclerosis, than those with ABI of ≥ 0.9 (32.2 ± 5.9 and 30.1 ± 6.2 ng/ml, respectively, P < 0.05). An association between low ABI and high serum s(P)RR levels was observed even after correction for age, history of smoking, HbA1c, and LDL-C. Serum s(P)RR levels were significantly higher in hemodialysis patients when compared with subjects with normal renal function, although s(P)RR is dialyzed to some extent, but to a lesser extent than creatinine. High serum s(P)RR levels may be associated with atherosclerosis independent of other risk factors, suggesting that serum s(P)RR could be used as a marker for atherosclerotic conditions in hemodialysis patients.

    Hemodialysis patients are at increased risk of infection by hepatitis C and B viruses, which are significant causes of mortality and morbidity. Prevention of their transmission in hemodialysis units remains a challenge worldwide. We aimed to investigate the prevalence of these two infections and to explore major risk factors among patients on chronic hemodialysis. We performed a cross-sectional study of 109 hemodialysis patients (mean duration of hemodialysis of seven years) between 2012 and 2014 in a Teaching Hospital of Monastir, Tunisia. Hepatitis B and C serological markers were searched for using a chemiluminescent assay. Genome detection was performed using a commercially available quantitative real-time PCR test. A total of 109 hemodialysis patients were enrolled (75 males and 34 females). Ages ranged from 21 to 81 years. Six (5.5%) of these 109 patients had HBV infection defined by a positive HBsAg in four (3.7%) patients and by a detectable DNA associated with an "isolated anti-HBc" profile in the remaining two patients. Hepatitis C was observed in eight patients (7.3%) and five of them had detectable RNA. Hemodialysis duration ˃5years was the main risk factor for hepatitis C infection (P=0.01; OR: 3.11; 95% CI [1.57-13.71]). Our findings confirm the downward trend of the prevalence of both hepatitis B and C infections among Tunisian hemodialysis patients. Hemodialysis duration remains the main risk factor for hepatitis C infection. Occult hepatitis B infection should be suspected and investigated, especially among patients with an "isolated anti-HBc" profile. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Background. Various biomarkers and assays have been used for assessment of (anti)oxidant status in hemodialysis patients, including those intended for measurement of serum total (anti)oxidants, most often as a part of panel biomarkers. Methods. Serum (anti)oxidant status was measured in 32 chronically hemodialyzed patients and in 47 healthy persons, using two oxidations and three antioxidant assays. Results. The patients before the hemodialysis session have had higher values of total oxidants in comparison to the healthy persons, with a further increase during the hemodialysis. These findings were confirmed with both oxidation assays, but they differ in the percentage of increase and the statistical significance. All three antioxidant assays showed significantly higher values of the total serum antioxidants in the patients before the hemodialysis session in comparison to the healthy persons, and their significant decrease during the hemodialysis. However, the assays differ in the percentage of decrease, its statistical significance, and the correlations with uric acid. Conclusion. The variability of results of total (anti)oxidants which are obtained using different assays should be taken into account when interpreting data from clinical studies of oxidative stress, especially in complex pathologies such as chronic hemodialysis.

    Retrospective studies suggest that online hemodiafiltration (OL-HDF) may reduce the risk of mortality compared with standard hemodialysis in patients with ESRD. We conducted a multicenter, open-label, randomized controlled trial in which we assigned 906 chronic hemodialysis patients either to continue hemodialysis (n=450) or to switch to high-efficiency postdilution OL-HDF (n=456). The primary outcome was all-cause mortality, and secondary outcomes included cardiovascular mortality, all-cause hospitalization, treatment tolerability, and laboratory data. Compared with patients who continued on hemodialysis, those assigned to OL-HDF had a 30% lower risk of all-cause mortality (hazard ratio [HR], 0.70; 95% confidence interval [95% CI], 0.53-0.92; P=0.01), a 33% lower risk of cardiovascular mortality (HR, 0.67; 95% CI, 0.44-1.02; P=0.06), and a 55% lower risk of infection-related mortality (HR, 0.45; 95% CI, 0.21-0.96; P=0.03). The estimated number needed to treat suggested that switching eight patients from hemodialysis to OL-HDF may prevent one annual death. The incidence rates of dialysis sessions complicated by hypotension and of all-cause hospitalization were lower in patients assigned to OL-HDF. In conclusion, high-efficiency postdilution OL-HDF reduces all-cause mortality compared with conventional hemodialysis.

    The study was planned as a case-control study to examine the effects of music on some of the complications experienced by chronic renal failure (CRF) patients during hemodialysis. A total of 60 patients (30 intervention and 30 control) diagnosed with end-stage renal failure undergoing hemodialysis treatment participated in this study. The study was conducted in Manisa Merkez Efendi State Hospital Hemodialysis Unit and Manisa Özel Anemon Hemodialysis between April 2012 and July 2012. The intervention group listened 30 minutes in each session (12 total sessions) Turkish art music at the beginning of the third hour of their hemodialysis sessions. Patient Information Form and visual analog scale to assess pain, nausea, vomiting, and cramps during hemodialysis session were used. For the analysis of data, the number, percentage, chi-square test, and significance test of independent group differences between two averages were conducted. According to the findings of the study, the average of the intervention and control group ages, respectively, was 50.86 ± 11.3 and 55.13 ± 9.68. The primary duration of hemodialysis treatment for both intervention and control groups was "1 year and above" (70.0%). The intervention group's pain and nausea scores were lower than the control group for all 12 sessions. The difference between the intervention and the control group's pain scores was significant (P < 0.05). However, in pain scores from the first session to 12th session, continuous decreasing trend was not observed. According to the results, music can be used as an independent nursing practice for reduction of complications for CRF patients receiving hemodialysis treatment. © 2014 International Society for Hemodialysis.

    Instantaneous wave-free ratio (iFR) is a vasodilator-free index and is reported to have a good correlation with fractional flow reserve (FFR). Hemodialysis patients exhibit left ventricular hypertrophy, reduced arterial compliance, and impaired microcirculation. Such a coronary flow condition in these patients may influence the relationship between iFR and FFR. This study assessed the impact of hemodialysis on the relationship between iFR and FFR. The study enrolled 196 patients with 265 stenoses who underwent assessment via iFR, FFR assessment, and right heart catheterization. A good correlation between iFR and FFR was observed in hemodialysis patients. iFR in the hemodialysis group was significantly lower than in the non-hemodialysis group (0.81 ± 0.13 vs. 0.86 ± 0.13, p = 0.005), although no significant difference was found in FFR and percentage diameter stenosis. An iFR value of 0.84 was found to be equivalent to an FFR value of 0.8 in hemodialysis patients, which was lower than the standard predictive iFR range for ischemia. Vasodilator-free assessment by iFR could be beneficial in evaluating intermediate coronary stenosis in patients receiving hemodialysis. However, the threshold for iFR abnormality needs adjustment in hemodialysis patients, and larger clinical trials are required to confirm the results in this specific subset.

    Background: Home hemodialysis is associated with lower costs to the health care system compared with conventional facility-based hemodialysis because of lower staffing and overhead costs, and by transferring the treatment cost of utilities (water and power) to the patient. The purpose of this study was to determine the utility costs of home hemodialysis and create a formula such that patients and renal programs can estimate the annual patient-borne costs involved with this type of treatment. Methods: Seven common combinations of treatment duration and dialysate flows were replicated 5 times using various combinations of home hemodialysis and reverse osmosis machines. Real-time utility (electricity and water) consumption was monitored during these simulations. A generic formula was developed to allow patients and programs to calculate a more precise estimate of utility costs based on individual combinations of dialysis intensity, frequency and utility costs unique to any patient. Results: Using typical 2014 utility costs for Edmonton, the most expensive prescription was for nocturnal home hemodialysis (8 h at 300 mL/min, 6 d/wk), which resulted in a utility cost of $1269 per year; the least expensive prescription was for conventional home hemodialysis (4 h at 500 mL/min, 3 d/wk), which cost $420 per year. Water consumption makes up most of this expense, with electricity accounting for only 12% of the cost. Interpretation: We show that a substantial cost burden is transferred to the patient on home hemodialysis, which would otherwise be borne by the renal program. PMID:28401120

    Background Peritonitis has been independently associated with increased morbidity and mortality in peritoneal dialysis patients. However, there are few reports on peritonitis in hemodialysis patients. We aim at investigating both the risk profiles and prognostic impact of peritonitis in hemodialysis patients. Methods This nation-wide longitudinal study uses claims data obtained from the Taiwan National Health Insurance Research Database. A total of 80,733 incident hemodialysis patients of age ≥ 20 years without a history of peritonitis were identified between January 1, 1998 and December 31, 2009. Predictors of peritonitis events were estimated using Cox proportional hazard models. Time-dependent Cox proportional hazard models were used to estimate hazard ratio for mortality attributed to peritonitis exposure. Results Of 80,733 incident hemodialysis patients over a 13-year study period, peritonitis was diagnosed in 935 (1.16%), yielding an incidence rate of 2.91 per 1000 person-years. Female gender, liver cirrhosis and polycystic kidney disease were three of the most significant factors for peritonitis in both non-diabetic and diabetic hemodialysis patients. The cumulative survival rate of patients with peritonitis was 38.8% at 1 year and 10.1% at 5 years. A time-dependent Cox multivariate analysis showed that peritonitis had significantly increased hazard ratio for all cause mortality. Additionally, the risk of mortality remained significantly higher for non-diabetic hemodialysis patients that experienced peritonitis. Conclusions The risk of peritonitis in hemodialysis patients is higher in female gender, liver cirrhosis and polycystic kidney disease. Although peritonitis is a rare condition, it is associated with significantly poorer outcome in hemodialysis patients. PMID:28301536

    Diabetic ketoacidosis (DKA) is a critical complication of type 1 diabetes associated with water and electrolyte disorders. Here, we report a case of DKA with extreme hyperkalemia (9.0 mEq/L) in a patient with type 1 diabetes on hemodialysis. He had a left frontal cerebral infarction resulting in inability to manage his continuous subcutaneous insulin infusion pump. Electrocardiography showed typical changes of hyperkalemia, including absent P waves, prolonged QRS interval and tented T waves. There was no evidence of total body water deficit. After starting insulin and rapid hemodialysis, the serum potassium level was normalized. Although DKA may present with hypokalemia, rapid hemodialysis may be necessary to resolve severe hyperkalemia in a patient with renal failure. Patients with type 1 diabetes on hemodialysis may develop ketoacidosis because of discontinuation of insulin treatment.Patients on hemodialysis who develop ketoacidosis may have hyperkalemia because of anuria.Absolute insulin deficit alters potassium distribution between the intracellular and extracellular space, and anuria abolishes urinary excretion of potassium.Rapid hemodialysis along with intensive insulin therapy can improve hyperkalemia, while fluid infusions may worsen heart failure in patients with ketoacidosis who routinely require hemodialysis.

The primary outcome was all-cause mortality, and secondary outcomes included cardiovascular mortality, all-cause hospitalization, treatment tolerability, and laboratory data. Compared with patients who continued on hemodialysis, those assigned to OL-HDF had a 30% lower risk of all-cause mortality (hazard ratio [HR], 0.70; 95% confidence interval [95% CI], 0.53–0.92; P=0.01), a 33% lower risk of cardiovascular mortality (HR, 0.67; 95% CI, 0.44–1.02; P=0.06), and a 55% lower risk of infection-related mortality (HR, 0.45; 95% CI, 0.21–0.96; P=0.03). The estimated number needed to treat suggested that switching eight patients from hemodialysis to OL-HDF may prevent one annual death. The incidence rates of dialysis sessions complicated by hypotension and of all-cause hospitalization were lower in patients assigned to OL-HDF. In conclusion, high-efficiency postdilution OL-HDF reduces all-cause mortality compared with conventional hemodialysis. PMID:23411788

    We present a case of post-operative iatrogenic quadriplegia, which occurred after subtotal parathyroidectomy. This patient was on long-term hemodialysis for 7 years. The need of prolonged neck extension for this procedure was probably the main risk factor for the spinal cord injury. Systemic hypotension which contributed to the injury in this case, should be anticipated and promptly treated to prevent further damage. Spinal deformities associated with end-stage renal disease may make such patients more susceptible. Since appropriate precautions against potential neurologic damage can be undertaken, we suggest that evaluating carefully for the pre-existing spinal stenosis before a procedure requiring prominent and prolonged hyper-extension of the neck, especially in long-term hemodialysis patients is of paramount importance.

    We hypothesized that the higher mortality for hemodialysis patients who live farther from the closest attending nephrologist compared with patients living closer might be due to lower quality of care. Population-based longitudinal study. All adult maintenance hemodialysis patients with measurements of quality-of-care indicators initiating hemodialysis therapy between January 2001 and June 2010 in Northern Alberta, Canada. Hemodialysis patients were classified into categories based on the distance by road from their residence to the closest nephrologist: ≤50 (referent), 50.1-150, 150.1-300, and >300 km. Quality-of-care indicators were based on published guidelines. Quality-of-care indicators at 90 days following initiation of hemodialysis therapy and, in a secondary analysis, at 1 year. Measurements were available for 1,784 patients. At baseline, the proportions of patients residing in each category were 69% for ≤50 km to closest nephrologist; 17%, 50.1-150 km; 7%, 150.1-300 km; and 7%, >300 km. Those who lived farther away from the closest nephrologist were less likely to have seen a nephrologist 90 days prior to the initiation of hemodialysis therapy (P for trend = 0.008) and were less likely to receive Kt/V of 1.2 (adjusted OR, 0.50; 95% CI, 0.30-0.84; P for trend = 0.01). Remote location also was associated with suboptimal levels of phosphate control (P for trend = 0.005). There were no differences in the prevalence of arteriovenous fistulas or grafts or hemoglobin levels across distance categories. Registry data with limited data for non-guideline-based quality indicators. Although several quality-of-care indicators were less common in remote-dwelling hemodialysis patients, these differences do not appear sufficient to explain the previously noted disparities in clinical outcomes by residence location.

    To determine the frequency of tuberculosis among hemodialysis patients in Togo, specify its different localizations and identify its diagnostic and therapeutic difficulties. This was a retrospective study over a period of 5 years (2010-2015). It includes the records of periodic hemodialysis patients in the Nephrology Department of the Sylvanus-Olympio University Teaching Hospital in Lomé. The diagnosis of tuberculosis was selected on the basis of clinical and laboratory data. The specific treatment has involved the association of 4 antituberculosis, which was adapted to the renal function. Of 91 chronic hemodialysis patients treated in Hospital Sylvanus-Olympio hemodialysis center, 10 cases (10.9%) of tuberculosis were diagnosed. The mean age was 37.3±12.8 years, and the sex ratio was 1.5. The median time to onset of tuberculosis after initiation of hemodialysis was 16.8±9 months. Extrapulmonary sites are found in 100% of cases (5 had both peritoneal and pleural localization, only 5 had pleural localization). The tuberculin skin test was positive in 4 patients (40%). The search for Mycobacterium tuberculosis was unsuccessful in all types of samples. Tuberculosis treatment was generally tolerated. Two patients (20%) had died during treatment. Tuberculosis is relatively common in hemodialysis patients. Diagnosis is difficult and may be based on the therapeutic trial. Copyright © 2016 Association Société de néphrologie.

    Hypoalbuminemia is a predictor of poor outcomes in dialysis patients. Among hemodialysis patients, there has not been prior study of whether residual kidney function or decline over time impacts serum albumin levels. We hypothesized that a decline in residual kidney function is associated with an increase in serum albumin levels among incident hemodialysis patients. In a large national cohort of 38,504 patients who initiated hemodialysis during 1/2007-12/2011, we examined the association of residual kidney function, ascertained by urine volume and renal urea clearance, with changes in serum albumin over five years across strata of baseline residual kidney function, race, and diabetes using case-mix adjusted linear mixed effects models. Serum albumin levels increased over time. At baseline, patients with greater urine volume had higher serum albumin levels: 3.44 ± 0.48, 3.50 ± 0.46, 3.57 ± 0.44, 3.59 ± 0.45, and 3.65 ± 0.46 g/dL for urine volume groups of <300, 300-<600, 600-<900, 900-<1,200, and ≥1,200 mL/day, respectively (P trend  < 0.001). Over time, urine volume and renal urea clearance declined and serum albumin levels rose, while the baseline differences in serum albumin persisted across groups of urinary volume. In addition, the rate of decline in residual kidney function was not associated with the rate of change in albumin. Hypoalbuminemia in hemodialysis patients is associated with lower residual kidney function. Among incident hemodialysis patients, there is a gradual rise in serum albumin that is independent of the rate of decline in residual kidney function, suggesting that preservation of residual kidney function does not have a deleterious impact on serum albumin levels. © 2016 International Society for Hemodialysis.

  17. Spiritual Well-Being, Depression, and Stress Among Hemodialysis Patients in Jordan.

    The spiritual dimension of a patient's life is an important factor that may mediate detrimental impacts on mental health. The lack of research investigating spiritual well-being, religiosity, and mental health among Jordanian hemodialysis patients encouraged this research. This study explored levels of spiritual well-being and its associations with depression, anxiety, and stress. A quantitative, cross-sectional correlational study. A sample of 218 Jordanian Muslim hemodialysis patients completed a structured, self-administered questionnaire. The data were analyzed using descriptive statistics and linear multivariate regression models. The hemodialysis patients had, on average, relatively low levels of spiritual well-being, moderate depression, severe anxiety, and mild to moderate stress. The results of the regression models indicated that aspects of spiritual well-being were negatively associated with depression, anxiety, and stress, but only existential well-being consistently retained significant associations after controlling for religious well-being, religiosity, and sociodemographic variables. Greater spiritual and existential well-being of Jordanian hemodialysis patients were significantly associated with less depression, anxiety, and stress. It appears that these patients use religious and spiritual beliefs and practices as coping mechanisms to overcome their depression, anxiety, and stress. The implications for holistic clinical practice are explored.

    Background: Chronic renal disease and hemodialysis cause numerous psychological, social, cultural, and spiritual challenges for both patients and their families. Overcoming these challenges is possible only through providing holistic support for the patients. Today, despite the support provided by family and professional caregivers for the patients, patients still express dissatisfaction with the support provided and believe it to be inadequate. In fact, patients and family caregivers and healthcare practitioners seem to have different understandings of the notion of support. Thus, the researcher decided to examine the concept of support from the viewpoint of hemodialysis patients. Materials and Methods: This descriptive phenomenological research was conducted on 17 patients with end-stage renal disease (ESRD) who were undergoing hemodialysis. Purposive sampling was performed and continued until data saturation. Data were collected through 30–60 min unstructured interviews and analyzed using Colaizzi's method. Results: From the analysis of data, 4 themes (psychological support, accompaniment, social support, and spiritual support) and 11 sub-themes were obtained. Psychological support consisted of two sub-themes of psychological support by healthcare practitioners and emotional support by family and relatives. Accompaniment included three sub-themes of assistance in transportation, providing and using medicine, and daily activities. Social support was identified with four sub-themes of promotion of the society's understanding of the patients’ condition, improvement of communication with others, the need for employment, and independence. Spiritual support was identified with two sub-themes of the need for faith and trust in God or Imams and the need to resolve spiritual contradictions. Conclusion: The results showed that from the viewpoint of the participants, the concept of support consisted of psychological support, social support, accompanying the patient

    Hemodialysis patients have high mortality rates, potentially reflecting underlying comorbid conditions and ongoing catabolism. Intradialytic oral nutritional supplements may reduce this risk. Retrospective propensity-matched cohort. Maintenance hemodialysis patients treated at Dialysis Clinic Inc facilities who were initiated on a nutritional supplement protocol in September to October 2010 were matched using a propensity score to patients at facilities at which the protocol was not used. Prescription of the protocol, whereby hemodialysis patients with serum albumin levels ≤3.5g/dL would initiate oral protein supplementation during the dialysis procedure. Sensitivity analyses matched on actual supplement intake during the first 3 study months. Covariates included patient and facility characteristics, which were used to develop the propensity scores and adjust multivariable models. All-cause mortality, ascertained though March 2012. Of 6,453 eligible patients in 101 eligible hemodialysis facilities, the protocol was prescribed to 2,700, and 1,278 of these were propensity matched to controls. Mean age was 61 ± 15 (SD) years and median dialysis vintage was 34 months. There were 258 deaths among protocol assignees versus 310 among matched controls during a mean follow-up of 14 months. In matched analyses, protocol prescription was associated with a 29% reduction in the hazard of all-cause mortality (HR, 0.71; 95% CI, 0.58-0.86); adjustment had minimal impact on models. In time-dependent models incorporating change in albumin level, protocol status remained significant but was attenuated in models incorporating a 30-day lag. Similar results were seen in sensitivity analyses of 439 patients receiving supplements who were propensity-matched to controls, with 116 deaths among supplement users versus 140 among controls (HR, 0.79; 95% CI, 0.60-1.05), achieving statistical significance in adjusted models.

    Familial Mediterranean Fever (FMF) is usually an autosomal recessive autoinflammatory disease characterized by recurrent attacks of fever and serositis. FMF develops before the age of 20 years in 90% of patients. It has intervals of 1 week to several years between attacks, which leads to renal dysfunction-amyloidosis. We report a case of atypical FMF that developed in a long-term hemodialysis patient. A 65-year-old Japanese female undergoing hemodialysis for 32 years was referred to our hospital with a fever of unknown origin (FUO) following cervical laminoplasty. The fever occurred as recurrent attacks accompanied by oligoarthralgia of the left hip and knee. We suspected FMF because of recurrent self-limited febrile attacks, although the patient showed atypical clinical features such as late-onset and highly frequent attacks. After receiving treatment, she achieved a complete response to colchicine. Therefore, a diagnosis of FMF was made based on the Tel-Hashomer criteria, which was confirmed by genetic testing. The case suggests that FMF may be of note in long-term hemodialysis patients developing FUO. © 2017 International Society for Hemodialysis.

    Patients undergoing hemodialysis have a higher rate of hepatitis C virus infection than the general population, and due to various factors including hemodialysis and immunosuppression, it is difficult to make a diagnosis. The appearance of direct-acting antiviral agents greatly promotes the treatment of hepatitis C, but there are still no adequate data on their effect and safety in patients undergoing hemodialysis. This article discusses the prevalence, diagnosis, and treatment of hepatitis C in patients undergoing hemodialysis.

    Introduction: Despite many advances in the treatment of chronic renal failure, the quality of sleep in patients who suffer from this disease is at the risk. The high prevalence of sleep disorders in hemodialysis patients, which is concomitant with physical, behavioral, and psychological problems, has always affected these patients' quality of life (QOL). This study aimed to determine the relationship between quality of sleep and quality of life in hemodialysis patients. Methods: By using a descriptive and correlational design, this study was conducted on 245 hemodialysis patients in 2012. Patients were selected by convenience sampling from the hemodialysis ward of four training hospitals of Tabriz and Maragheh. Quality of sleep was measured by the Pittsburgh Sleep Quality Index (PSQI), and the quality of life for patients was measured by the Kidney Disease Quality Of Life questionnaire (KDQOL-SF). Results: 83.3% of hemodialysis patients had poor quality of sleep. Poor quality of life was significantly associated with poor quality of sleep. There was a significant negative correlation between global PSQI and important aspects of quality of life including physical health, symptoms and problems, the impact of kidney disease on daily life, burden of kidney disease, mental health, social support, and sexual function. Conclusion: The low quality of sleep in hemodialysis patients has an effect on the deterioration of their quality of life. Therefore, training, counseling, and advocacy programs should be developed to improve the patients' quality of sleep and quality of life, especially those with lower education level and income, and older people.

    Fibroblast growth factor-23 (FGF-23) levels start rising early in patients with chronic kidney disease and is implicated in cardiovascular and overall mortality of hemodialysis patients. We conducted a prospective observational cohort study in stable dialysis patients looking into the levels of FGF-23 in hemodialysis patients and its association with various demographic and biochemical variables and mortality. A total of 91 patients were enrolled in the study. The mean FGF-23 levels were very high (1152.7 pg/ml). FGF-23 levels were significantly associated with serum phosphorus and parathyroid hormone (PTH) levels in univariate and multivariate analysis. No significant association between FGF-23 and cardiovascular comorbidities and overall mortality was seen. FGF-23 levels rise exponentially in maintenance hemodialysis patients. There is a strong association between FGF-23 and phosphorus and PTH levels. No association between FGF-23 and mortality was noted in our patients.

    Background Higher numbers of registered nurses per patient have been associated with improved patient outcomes in acute care facilities. Variation and associations of patient-care staffing levels and hemodialysis facility characteristics have not been previously examined. Study Design Cross-sectional study using Poisson regression to examine associations betwee patient-care staffing levels and hemodialysis facility characteristics. Setting & Participants 4,800 U.S. hemodialysis facilities in the 2009 CMS ESRD Annual Facility Survey (CMS-2744), USRDS. Predictors Facility characteristics, including profit status, freestanding status, chain affiliatio and geographic region, adjusted for facility size, capacity, functional type, and urbanicity. Outcomes Patient care staffing levels, including ratios of Registered Nurses (RN), Licensed Practical Nurses (LPN), Patient Care Technicians (PCT), composite staff (RN+LPN+PCT), Social Workers, and Dietitians to in-center hemodialysis patients. Results After adjusting for background facility characteristics, the ratios of RNs and LPNs to patients were 35% (p<0.001) and 42% (p<0.001) lower, but the PCT-to-patient ratio was 16% (p<0.001) higher in for-profit facilities than those in nonprofit facilities (Rate ratio, 0.65, 95%CI, 0.63–0.68; 0.58, 0.51–0.65; 1.16, 1.12–1.19; respectively). Regionally, compared to the Northeast, the adjusted RN-to-patient ratio was 14% (p< 0.001) lower in the Midwest, 25% (p< 0.001) lower in the South, and 18% (p< 0.001) lower in the West. Even after additional adjustments, the large for-profit chains had significantly lower RN and LPN ratios than the largest nonprofit chain, but a significantly higher PCT-to-patient ratio. The overall composite staffing levels were also lower in for-profit and chain-affiliated facilities. The patterns hold when the hospital-based units were excluded. Limitations Nursing hours were not available. Conclusions The significant variation in patient-care staffing

    Patients who undergo hemodialysis encounter challenges including role changes, physical degeneration, and difficulty in performing activities of daily living (ADLs) and self-care. These challenges deteriorate their physiological and psychosocial conditions, resulting in depression. High resilience (RES) and social support can alleviate stress and depression. This study evaluated the importance of RES and social support in managing depression in elderly patients undergoing maintenance hemodialysis (HD). In this descriptive, correlational study, 194 older patients undergoing HD were enrolled from the HD centers of three hospitals in northern Taiwan. The Barthel ADL Index, RES scale, Inventory of Socially Supportive Behavior, and Beck Depression Inventory-II were used. Hierarchical regression analysis was applied to evaluate the interaction of RES and social support with illness severity, demographics, and ADLs. Of the total participants, 45.9% experienced depressive symptoms. Demographic analysis showed that men and those with high educational level and income and financial independence had less depression ( p <0.01). Patients with a higher Barthel Index (n=103), RES scale (n=33), and social support (n=113) showed less depressive symptoms ( p <0.01). We found a significant negative correlation between depressive symptoms and social support ( r =-0.506, p <0.01) and RES ( r =-0.743, p <0.01). Hierarchical regression analysis showed that RES could buffer the effects of symptom severity on depression ( b =-0.436, p <0.01), but social support did not exert a buffering effect. The severity of illness symptoms and ADLs were the major determinants of depressive symptoms. High RES could alleviate depressive symptoms in the older patients undergoing HD.

    Although hemodialysis treatment has greatly increased the life expectancy of end stage renal disease patients, low quality of life among hemodialysis patients is frequently reported. This cross-sectional study aimed to determine the relationship between medical history, hemodialysis treatment and nutritional status with the mental and physical components of quality of life in hemodialysis patients. Respondents (n=90) were recruited from Hospital Kuala Lumpur and dialysis centres of the National Kidney Foundation of Malaysia. Data obtained included socio-demography, medical history, hemodialysis treatment and nutritional status. Mental and physical quality of life were measured using the Mental Composite Summary (MCS) and Physical Composite Summary (PCS) of the Short-Form Health Survey 36-items, a generic core of the Kidney Disease Quality of Life Short Form. Two summary measures and total SF-36 was scored as 0–100, with a higher score indicating better quality of life. Approximately 26 (30%) of respondents achieved the body mass index (24 kg/m2) and more than 80% (n=77) achieved serum albumin level (>35.0 mg/dL) recommended for hemodialysis patients. The majority of respondents did not meet the energy (n=72, 80%) and protein (n=68,75%) recommendations. The total score of SF-36 was 54.1±19.2, while the score for the mental and physical components were 45.0±8.6 and 39.6±8.6, respectively. Factors associated with a higher MCS score were absence of diabetes mellitus (p=0.000) and lower serum calcium (p=0.004), while higher blood flow (p=0.000), higher serum creatinine (p=0.000) and lower protein intake (p=0.006) were associated with a higher PCS score. To improve the overall quality of life of hemodialysis patients, a multidisciplinary intervention that includes medical, dietetic and psychosocial strategies that address factors associated with mental and physical quality of life are warranted to reduce further health complications and to improve quality of life

    Extended-hours hemodialysis offers substantially longer treatment time compared to conventional hemodialysis schedules and is associated with improved fluid and electrolyte control and favorable cardiac remodeling. However, whether extended-hours hemodialysis improves survival remains unclear. Therefore, we determined the association between extended-hours compared to conventional hemodialysis and the risk of all-cause mortality in a nationally representative cohort of patients initiating maintenance dialysis in the United States from 2007 to 2011. Survival analyses using causal inference modeling with marginal structural models were performed to compare mortality risk among 1,206 individuals undergoing thrice weekly extended-hours hemodialysis or 111,707 patients receiving conventional hemodialysis treatments. The average treatment time per session for extended-hours hemodialysis was 399 minutes compared to 211 minutes for conventional therapy. The crude mortality rate with extended-hours hemodialysis was 6.4 deaths per 100 patient-years compared with 14.7 deaths per 100 patient-years for conventional hemodialysis. In the primary analysis, patients treated with extended-hours hemodialysis had a 33% lower adjusted risk of death compared to those who were treated with a conventional regimen (95% confidence interval: 7% to 51%). Additional analyses accounting for analytical assumptions regarding exposure and outcome, facility-level confounders, and prior modality history were similar. Thus, in this large nationally representative cohort, treatment with extended-hours hemodialysis was associated with a lower risk for mortality compared to treatment with conventional in-center therapy. Adequately powered randomized clinical trials comparing extended-hours to conventional hemodialysis are required to confirm these findings. PMID:27555118

    The purpose of this study was to examine the relationship between contingency contracting and adherence to prescribed therapy in outpatient chronic hemodialysis patients. A quasi-experimental, pretest/posttest design was used. The sample included 15 hemodialysis patients, 6 in the phosphorus group and 9 in the weight-gain group. The study was conducted at an outpatient hemodialysis center in a Midwestern rural state. Specific variables investigated were interdialytic weight gains and serum phosphorus levels that reflect adherence to fluid restrictions and to taking phosphate-binding medications. Weekly interviews were conducted with each patient and content analysis of interview data was completed to identify categories related to adherence and nonadherence. Pre- and postcontract weight gains and phosphorus levels were analyzed with a paired two sample t-test. The categories related to adherence and nonadherence included physiological, psychological, environmental, locus of control/self-control/self-praise, economical, medical, knowledge deficit, health benefits, family support, and social support. Adherence to taking phosphate-binding medication responded more favorably to contingency contracting than did adherence to fluid restrictions. Chronic outpatient hemodialysis patients in the sample responded to the use of contingency contracting and developed techniques to remember to take phosphate-binding medications in order to lower serum phosphorus medications.

    Acidosis is associated with protein-energy malnutrition, inflammation, and bone disease, and low bicarbonate levels have been implicated in higher mortality rates in chronic kidney disease. Recently, the concentration of serum pregnancy-associated plasma protein-A (PAPP-A) has become accepted as a prognostic marker in hemodialysis patients. This study determined the relationship between PAPP-A and bicarbonate levels in these patients. The study enrolled 65 hemodialysis patients (41 males, 24 females) and 26 control subjects (11 males, 15 females). Serum PAPP-A, intact parathormone (iPTH), calcium, phosphorus (P), and bicarbonate levels were measured. Correlations between PAPP-A and bicarbonate, iPTH, calcium, and phosphorus were evaluated. Median PAPP-A levels were significantly higher in hemodialysis patients [15.1 (<0.03-158.8) ng/ml] than in control subjects [6.6 (<0.03-16.4) ng/ml] (P < 0.05). There were statistically significant correlations between serum PAPP-A and bicarbonate, iPTH, and P in hemodialysis patients but not in control subjects. Elevation of serum PAPP-A has been found in hemodialysis patients and its significant correlation with bicarbonate suggests that it may be a prognostic factor. © 2014 Wiley Periodicals, Inc.

    Splenic abscess is an unusual condition usually seen in immunocompromised patients or associated with intravenous drug abuses. Several conditions including trauma, immunodeficiency, corticosteroid and/or immunosuppressive therapy and diabetes mellitus have been listed under the predisposing factors for a splenic abscess. Splenic abscess in a patient on hemodialysis is a rare but life-threatening condition if not corrected. We describe a case of splenic abscess with bacterial endocarditis on maintenance hemodialysis. He had staphylococcal septicemia secondary to bacterial endocarditis at the mitral valve from the dialysis accesssite infection. Although hematologic seeding from endocarditis has been the predisposing factor for splenic abscess, we postulate that access-site infections may predispose hemodialysis patients to splenic abscess. Splenic abscess may be considered as one of the causes when patients on hemodialysis develop unexplained fever. PMID:15832007

    Hemodialysis is the most advanced form of artificial renal support. It ensures the survival of almost 2 million patients wordwide. Considerable progress has been made in recent years thanks to a better understanding of uremia, optimization of treatment modalities and more personalized treatment schedules. Increase of uremic toxins removal, improvement of hemodynamic tolerance of the sessions, reduction of proinflammatory reactions due to the bioincompatibility system are major advances that may explain the reduction of morbidity and mortality in dialysis patients. New technologies (nanotechnology, biotechnology, microelectronics) are now expected to introduce further progresses by miniaturizing devices and providing them with an "artificial intelligence" capable of interacting with the patient. The main obstacle remains ageing of uremic patients, increasing prevalence of comorbidities and shortage of social resources that are not conducive to innovation. By promoting a more physiological, longer and more effective hemodialysis performed at home with help of teledialysis monitoring that would probably be an interesting option to evaluate on a medico-economical point of view.

    The aim of this study was to evaluate whether adherence to treatment is associated with hospitalization risk in hemodialysis patients. We completed a cohort analysis of risk factors during 1 census month (November) and 1 year of follow-up during 5 consecutive years (2002-2006) in all end-stage renal disease patients hemodialyzed in the Kaunas region. During the census month, we collected data on noncompliance defined as (i) skipping of a hemodialysis (HD) session, (ii) shortening of 1 or more HD sessions, (iii) presence of hyperkalemia, (iv) presence of hyperphosphatemia, or (v) interdialytic weight gain (IDWG). In addition, data on age, sex, disability status, comorbidities, anemia control, malnutrition and inflammation, calcium-phosphorus metabolism and hospitalization rate were collected. Relative risk of hospitalization was estimated using Cox regression evaluating time to first hospitalization. We analyzed 559 patients for a total of 1,163 patient-years during the 5 years of the study. On multivariate analysis, adjusting for ischemic heart disease, diabetes mellitus, higher number of comorbid conditions, higher systolic blood pressure before dialysis, worse disability status, lower hemoglobin, albumin and urea before dialysis, the relative risk for hospitalization increased by 1.1 for every additional percentage point of IDWG and by 1.19 with each 1 mmol/L rise of serum phosphorus level. Skipping or shortening of hemodialysis sessions and serum potassium level were not associated with hospitalization. Higher IDWG and higher serum levels of phosphorus independently increased the relative risk of hospitalizations in hemodialysis patients. With skipped and shortened dialysis sessions, higher serum potassium level was not associated with hospitalization risk.

    Health-related quality of life and heart rate variability are often depressed in patients on hemodialysis. This pilot program used a simple holistic, self-directed breathing technique designed to improve heart rate variability, with the hypothesis that improving heart rate variability would subsequently enhance health-related quality of life. Patient self-reported benefits included reductions in anxiety, fatigue, insomnia, and pain. Using holistic physiologic techniques may offer a unique and alternative tool for nurses to help increase health-related quality of life in patients on hemodialysis.

    Venous anomalies are diagnostic and therapeutic challenges. Subclavian or superior vena cava stenosis can be developed and venous return can be achieved via cardiac veins and coronary sinus in patients with central venous catheter for long-term hemodialysis. These types of abnormalities are not extremely rare especially in patients with a history of central venous catheter placement. Detection of these anomalies and subclavian vein stenosis before the surgical creation of hemodialysis fistulae or tunneled central venous catheter placement may prevent unnecessary interventions in those patients. Multidetector computed tomography (MDCT) technique can give further information when compared with fluoroscopy or digital subtraction angiography in the management of these patients. This case report describes interesting aspects of central vein complications in hemodialysis patients. As a conclusion, there are limited data about thoracic venous return, and further prospective studies with large patient number are required. MDCT with 3D reconstruction is particularly useful for the accurate evaluation of venous patency, variations, and collateral circulation. Also it is an excellent tool for choosing and planning treatment.

    Background and objectives Patient centeredness is widely advocated as a cornerstone of health care, but it is yet to be fully realized, including in nephrology. Our study aims to describe nephrologists’ perspectives on defining and implementing patient-centered outcomes in hemodialysis. Design, setting, participants, & measurements Face-to-face, semistructured interviews were conducted with 58 nephrologists from 27 dialysis units across nine countries, including the United States, the United Kingdom, Australia, Austria, Belgium, Canada, Germany, Singapore, and New Zealand. Transcripts were thematically analyzed. Results We identified five themes on defining and implementing patient-centered outcomes in hemodialysis: explicitly prioritized by patients (articulated preferences and goals, ascertaining treatment burden, defining hemodialysis success, distinguishing a physician-patient dichotomy, and supporting shared decision making), optimizing wellbeing (respecting patient choice, focusing on symptomology, perceptible and tangible, and judging relevance and consequence), comprehending extensive heterogeneity of clinical and quality of life outcomes (distilling diverse priorities, highly individualized, attempting to specify outcomes, and broadening context), clinically hamstrung (professional deficiency, uncertainty and complexity in measurement, beyond medical purview, specificity of care, mechanistic mindset [focused on biochemical targets and comorbidities], avoiding alarm, and paradoxical dilemma), and undermined by system pressures (adhering to overarching policies, misalignment with mandates, and resource constraints). Conclusions Improving patient-centered outcomes is regarded by nephrologists to encompass strategies that address patient goals and improve wellbeing and treatment burden in patients on hemodialysis. However, efforts are hampered by ambiguities about how to prioritize, measure, and manage the plethora of critical comorbidities and broader

    Secondary hyperparathyroidism (SHPT) is a common problem in patients with end-stage renal disease. In cases with severe and resistant SHPT, surgical parathyroidectomy (PTX) is recommended. Hungry bone syndrome (HBS) following surgical PTX is most often associated with hypocalcemia and hypophosphatemia. The mechanisms for the HBS are not clear, and a method for its prevention has not been established. We present three hemodialysis patients with persistant hypophosphatemia after PTX. In our parathyroidectomized patients, hypocalcemia could be corrected with calcium and vitamin D treatment, but hypophosphatemia continued for eight months in one patient and in two other patients until the last visit (10 and 2 months, respectively). Predisposing factors such as old age, diabetes mellitus and parathyroid adenoma were not found in our patients. All three patients were younger (<35 years old) and anuric. Hemodialysis durations were seven, three and two years. In summary, HBS presented with hypocalcemia, and especially hypophosphatemia cannot be developed uncommonly and may persist for a long time following PTX in HD patients.

    Walking ability is significantly lower in hemodialysis patients compared to healthy people. Decreased walking ability characterized by slow walking speed is associated with adverse clinical events, but determinants of decreased walking speed in hemodialysis patients are unknown. The purpose of this study was to identify factors associated with slow walking speed in ambulatory hemodialysis patients. Subjects were 122 outpatients (64 men, 58 women; mean age, 68 years) undergoing hemodialysis. Clinical characteristics including comorbidities, motor function (strength, flexibility, and balance), and maximum walking speed (MWS) were measured and compared across sex-specific tertiles of MWS. Univariate and multivariate logistic regression analyses were performed to examine whether clinical characteristics and motor function could discriminate between the lowest, middle, and highest tertiles of MWS. Significant and common factors that discriminated the lowest and highest tertiles of MWS from other categories were presence of cardiac disease (lowest: odds ratio [OR] = 3.33, 95% confidence interval [CI] = 1.26–8.83, P<0.05; highest: OR = 2.84, 95% CI = 1.18–6.84, P<0.05), leg strength (OR = 0.62, 95% CI = 0.40–0.95, P<0.05; OR = 0.57, 95% CI = 0.39–0.82, P<0.01), and standing balance (OR = 0.76, 95% CI = 0.63–0.92, P<0.01; OR = 0.81, 95% CI = 0.68–0.97, P<0.05). History of fracture (OR = 3.35, 95% CI = 1.08–10.38; P<0.05) was a significant factor only in the lowest tertile. Cardiac disease, history of fracture, decreased leg strength, and poor standing balance were independently associated with slow walking speed in ambulatory hemodialysis patients. These findings provide useful data for planning effective therapeutic regimens to prevent decreases in walking ability in ambulatory hemodialysis patients. PMID:27018891

    Hepatitis B and C virus infection is a lead cause of morbidity and mortality among hemodialysis patients. Yet, little research has focused on the morbidity measures of these serious disorders in low and middle income countries. The study aims to estimate the prevalence of hepatitis B and C among hemodialysis patients in the West Bank hospitals in Palestine. A retrospective medical records review design was performed for all governmental and private hospitals in the West Bank which provide hemodialysis services for the patients. Data was retrieved from the patients' medical files and from the computerized health information system in some hemodialysis centers. SPSS software version 16 was used for data entry and analysis. In overall, 868 hemodialysis patients attending nine hemodialysis hospitals in the West Bank was recruited. The overall prevalence of hepatitis B virus was found to be 3.8% (33 cases) with a range from 0.0% (in Jericho and Qalqelia districts) to 11.8% (in Bethlehem district). Regarding hepatitis C virus, the overall prevalence was estimated around 7.4% (64 cases) with a range from 2.9% (in Nablus district) to 15.9% (in Qalqelia district). Although relatively low prevalence of both hepatitis B and C virus was found in a couple of hemodialysis hospitals, some higher prevalence values urge for the implementation of stricter infection prevention measures and more effective follow up procedures.

    Recently, rocuronium with subsequent use of sugammadex was proposed for electroconvulsive therapy (ECT) as an alternative to succinylcholine. Because sugammadex is cleared via the kidney with no metabolism, it is unknown that rocuronium-sugammadex use is safe in hemodialysis patients who received ECT. In this case report, we used rocuronium with subsequent administration of sugammadex in a 69-year-old female, hemodialysis patient, scheduled for ten ECT sessions for severe major depression. In the initial eight sessions, we tested the feasibility of rocuronium-sugammadex use for ECT. During the series of four ECT sessions, we measured plasma concentrations for the sum of sugammadex and sugammadex-rocuronium complex and observed whether possible residual sugammadex affected muscle relaxation during subsequent sessions of ECT. The results showed the feasibility of rocuronium-sugammadex use as muscle relaxants for ECT in patients undergoing hemodialysis. However, an accumulation of sugammadex did occur even after two sessions of hemodialysis, and residual sugammadex decreased the effect of the rocuronium given in the subsequent ECT sessions. Rocuronium-sugammadex was successfully utilized as muscle relaxants for ECT in this patient. Our experience in this case may indicate that if succinylcholine is contraindicated, rocuronium-sugammadex can be an alternative method for muscle relaxation during ECT in patients undergoing hemodialysis. When this rocuronium-sugammadex procedure is used, the effect of residual sugammadex after hemodialysis on the subsequently administered rocuronium should be considered.

    Kidney failure requiring hemodialysis is a chronic illness that has physical, psychosocial, and financial consequences. Patients with kidney failure receiving hemodialysis need a renewed focus on self-care, prevention, and community-based health management to reduce healthcare costs and complications, and improve outcomes and quality of life, while living with an altered lifestyle. A holistic chronic care model was applied as a guideline for healthcare professionals involved with this population to more effectively engage people with kidney failure in their management of their hemodialysis access.

    In this study, we used a prevalent cross-sectional sample of French hemodialysis patients from Dialysis Outcomes and Practice Patterns Study (DOPPS) 2 (2002-2004) to determine the percentage of patients whose values failed to meet targets in six different areas of hemodialysis practice (dialysis dose, anemia, serum phosphorus (PO(4)), serum calcium (Ca), serum albumin and catheter use for vascular access). Cox survival models, with adjustments for patient characteristics, were used for these analyses to estimate mortality hazard ratios (HR). Based on the mortality HR, the fraction of patients outside each target and the total HD population in France, we estimated the number of patient life years that could potentially be gained if every chronic, in-center hemodialysis patient in France who is currently outside of the specified target was able to achieve it. The proportion of patients failing to meet one of the six practice targets in France varied from 15% (dialysis dose) to 75% (albumin) while the percentage of patients complying with all six targets was restricted to 1.2%. The relative risk of mortality (RR) associated with being outside these targets varied from 1.12 to 1.46. Based on these two measures the life-years survival was estimated. The projected number of patients and life years potentially gained from adherence to the six targets was estimated close to 10,600 years-patient. In conclusion, this study suggests large opportunities to improve hemodialysis patient care in France still exist. Compliance with two major practice targets, such as albumin and restriction of catheter use will save highly significant life years of hemodialysis patient. Implementing and strict adherence to national and international guidelines should serve as a basic inspiration for continual improvement of hemodialysis patient care.

    This study examined whether racial/ethnic differences in illness perceptions exist among patients on maintenance hemodialysis. One hundred sixty-one patients with end stage renal disease (ESRD) undergoing maintenance hemodialysis (20% African Americans, 44% Hispanics, 9% Filipinos, and 27% Koreans) completed the Revised Illness Perception Questionnaire. Korean participants had higher emotional disturbance than their counterparts, whereas African-American participants had higher negative perceptions of personal intervention or medical treatment controlling their disease. This study indicates that patients from different racial/ethnic backgrounds undergoing maintenance hemodialysis may perceive their disease differently. This phenomenon could affect clinical outcomes and may require different therapeutic approaches. PMID:22480051

    Background The utilization of short-term daily hemodialysis has increased over the last few years, but little is known on its effects on the control of serum phosphate and fibroblast growth factor 23 (FGF23) levels. Methods We therefore performed a cross-sectional study to compare FGF23 levels as well as other biochemical variables between 24 patients undergoing short daily hemodialysis using the NxStage System® and 54 patients treated with conventional in-center hemodialysis. FGF23 levels were measured using the second-generation Immutopics® C-terminal assay. Results Short daily hemodialysis patients were younger than patients on conventional hemodialysis but there were no differences between groups in the duration of end-stage renal disease nor in the number of patients with residual renal function. A greater number of short daily hemodialysis patients received vitamin D sterol therapy than did conventional in-center hemodialysis patients while there were no differences in the use of different phosphate binders and calcimimetic therapy between groups. Overall serum calcium, phosphorus and intact parathyroid hormone levels were similar between groups. While serum phosphorus levels correlated with FGF23 concentrations in each group separately [r = 0.522 (P < 0.01) and r = 0.42 (P < 0.01) in short daily and conventional in-center hemodialysis, respectively], FGF23 levels were lower [823 RU/mL (263, 2169)] in the patients receiving short daily hemodialysis than in patients treated with conventional hemodialysis [2521 RU/mL (909, 5556)] (P < 0.01 between groups). Conclusions These findings demonstrate that FGF23 levels are significantly lower in short daily hemodialysis patients and suggest that FGF23 levels may be a more sensitive biomarker of cumulative phosphate burden than single or multiple serum phosphorus determinations in patients treated with hemodialysis.

    This study was done to examine the relation of uncertainty, uncertainty appraisal, and self-management in patients undergoing hemodialysis, and to identify factors influencing self-management. A convenience sample of 92 patients receiving hemodialysis was selected. Data were collected using a structured questionnaire and medical records. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlations and multiple regression analysis with the SPSS/WIN 20.0 program. The participants showed a moderate level of uncertainty with the highest score being for ambiguity among the four uncertainty subdomains. Scores for uncertainty danger or opportunity appraisals were under the mid points. The participants were found to perform a high level of self-management such as diet control, management of arteriovenous fistula, exercise, medication, physical management, measurements of body weight and blood pressure, and social activity. The self-management of participants undergoing hemodialysis showed a significant relationship with uncertainty and uncertainty appraisal. The significant factors influencing self-management were uncertainty, uncertainty opportunity appraisal, hemodialysis duration, and having a spouse. These variables explained 32.8% of the variance in self-management. The results suggest that intervention programs to reduce the level of uncertainty and to increase the level of uncertainty opportunity appraisal among patients would improve the self-management of hemodialysis patients.

    Background Patients undergoing hemodialysis frequently report pain with multifactorial causes, not limited to that experienced directly from hemodialysis treatment. Their pain may be nociceptive, neuropathic, somatic or visceral in nature. Despite this, pain in this population remains under-recognized and under-treated. Although several tools have been used to measure pain in patients undergoing hemodialysis as reported in the literature, none of them have been validated specifically in this population. The objective for this review was to compare and contrast these pain assessment tools and discuss their clinical utility in this patient population. Methods To identify pain assessment tools studied in patients undergoing hemodialysis, a literature search was performed in PubMed and Medline. An expert panel of dialysis and pain clinicians reviewed each tool. Each pain assessment tool was assessed on how it is administered and scored, its psychometric properties such as reliability, validity and responsiveness to change, and its clinical utility in a hemodialysis population. Brief Pain Inventory, McGill Pain Questionnaire, Pain Management Index, Edmonton Symptom Assessment System, Visual Analogue Scale and Faces Pain Scale were evaluated and compared. Results This assessment will help clinicians practicing in nephrology to determine which of these pain assessment tools is best suited for use in their individual clinical practice. PMID:25852910

    Hemodialysis patients are at greater risk of cardiovascular disease. Higher than expected cardiovascular morbidity and mortality in this population has been attributed to dislipidemia as well as inflammation. The causes of inflammation in hemodialysis patients are multifactorial. Several markers were used for the detection of inflammatory reaction in patients with chronic renal disease. These markers can be used for the prediction of future cardiovascular events. Among the several parameters of inflammatory markers, serum, CRP is well known and its advantages for the detection of inflammation and its predictor ability has been evaluated in several studies. This review addressed the associated factors and markers of inflammation in hemodialysis patients. In addition, their ability in predicting future atherosclerosis and effect of treatment has been reviewed.

This cross-sectional study took place throughout the month of September, 2012, in the hemodialysis center of the Sylvanus Olympio University Hospital, the only such center in Togo. The study included 65 patients, with a mean age of 49.5 years (range: 22 to 77 years), more often men (sex ratio: 1.82) and married (74 %). More than half (58%) had completed secondary education, while 73% belonged to the least advantaged socioeconomic class; 61 (94%) had health insurance, and 57% had been on dialysis for 1 to 4 years. The compliance rate was 11%. The main factors associated with good adherence were marital status (p = 0.0339) and the patient's general health status (p = 0.001). Treatment fatigue (p = 0.0347), forgetfulness (p = 0.0001), dosage forms and drug characteristics (p = 0.0198) were all factors of noncompliance. Therapeutic non-compliance was proportional to the number of drugs prescribed (p = 0.4263). Adherence in hemodialysis patients in Togo is very poor.

    Patients receiving hemodialysis often perceive their caregivers are overburdened. We hypothesize that increasing hemodialysis frequency would result in higher patient perceptions of burden on their unpaid caregivers. In two separate trials, 245 patients were randomized to receive in-center daily hemodialysis (6 days/week) or conventional hemodialysis (3 days/week) while 87 patients were randomized to receive home nocturnal hemodialysis (6 nights/week) or home conventional hemodialysis for 12 months. Changes in overall mean scores over time in the 10-question Cousineau perceived burden scale were compared. In total, 173 of 245 (70%) and 80 of 87 (92%) randomized patients in the Daily and Nocturnal Trials, respectively, reported having an unpaid caregiver at baseline or during follow-up. Relative to in-center conventional dialysis, the 12-month change in mean perceived burden score with in-center daily hemodialysis was -2.1 (95% confidence interval, -9.4 to +5.3; P=0.58). Relative to home conventional dialysis, the 12-month change in mean perceived burden score with home nocturnal dialysis was +6.1 (95% confidence interval, -0.8 to +13.1; P=0.08). After multiple imputation for missing data in the Nocturnal Trial, the relative difference between home nocturnal and home conventional hemodialysis was +9.4 (95% confidence interval, +0.55 to +18.3; P=0.04). In the Nocturnal Trial, changes in perceived burden were inversely correlated with adherence to dialysis treatments (Pearson r=-0.35; P=0.02). Relative to conventional hemodialysis, in-center daily hemodialysis did not result in higher perceptions of caregiver burden. There was a trend to higher perceived caregiver burden among patients randomized to home nocturnal hemodialysis. These findings may have implications for the adoption of and adherence to frequent nocturnal hemodialysis.

    The increase in the number of patients under hemodialysis treatment is a universal problem. With regard to the fact that there have been few social-psychological studies conducted on patients under hemodialysis treatment, the current study was conducted to investigate anxiety and perceived social support and the relation between them among these patients. This cross-sectional study was conducted on 126 patients under hemodialysis treatment in Isfahan in 2012. After randomly selecting a hospital with a hemodialysis ward, purposive sampling was conducted. Data collection tools included state-trait anxiety and perceived social support inventory. The data were analyzed using the Spearman correlation coefficient. Among the participants, 68.3% received average perceived social support. In addition, perceiving the tangible dimension of support was lower compared to other dimensions (Mean 40.02). Level of trait and state anxiety (65 and 67.5%) of over half of the participants was average. There was in inverse relationship between state and trait anxiety and total perceived social support and emotional and information dimensions (r = -0.340, r = -0.229). State and trait anxiety had the highest relation with emotional and information dimension of social support, respectively. Patients under hemodialysis treatment suffer from numerous psychological and social problems. Low awareness and emotional problems result in the increase of anxiety and reduction of perceived social support. Reduction of social support has negative effect on treatment outcomes.

    Background Patients who undergo hemodialysis encounter challenges including role changes, physical degeneration, and difficulty in performing activities of daily living (ADLs) and self-care. These challenges deteriorate their physiological and psychosocial conditions, resulting in depression. High resilience (RES) and social support can alleviate stress and depression. This study evaluated the importance of RES and social support in managing depression in elderly patients undergoing maintenance hemodialysis (HD). Patients and methods In this descriptive, correlational study, 194 older patients undergoing HD were enrolled from the HD centers of three hospitals in northern Taiwan. The Barthel ADL Index, RES scale, Inventory of Socially Supportive Behavior, and Beck Depression Inventory-II were used. Hierarchical regression analysis was applied to evaluate the interaction of RES and social support with illness severity, demographics, and ADLs. Results Of the total participants, 45.9% experienced depressive symptoms. Demographic analysis showed that men and those with high educational level and income and financial independence had less depression (p<0.01). Patients with a higher Barthel Index (n=103), RES scale (n=33), and social support (n=113) showed less depressive symptoms (p<0.01). We found a significant negative correlation between depressive symptoms and social support (r=−0.506, p<0.01) and RES (r=−0.743, p<0.01). Hierarchical regression analysis showed that RES could buffer the effects of symptom severity on depression (b=−0.436, p<0.01), but social support did not exert a buffering effect. Conclusion The severity of illness symptoms and ADLs were the major determinants of depressive symptoms. High RES could alleviate depressive symptoms in the older patients undergoing HD.

    Adherence to diet and fluid restrictions by adults on hemodialysis treatment is challenging. This study compared non-adherence (NA) to diet and fluid restrictions between adult US and German hemodialysis patients, and assessed potential predictors for NA. A cross-sectional multicenter comparative study of 456 adult hemodialysis patients was conducted in 12 outpatient-based hemodialysis centers in the United States and Germany. NA was based on self-report using the Dialysis Diet and Fluid Non-adherence Questionnaire (DDFQ). Laboratory marker, interdialytic weight gain (IDWG) and dialysis adequacy (Kt/V) information were obtained from medical records. Mean time on dialysis was 50 months (range 3-336); mean age was 62 years (range 19-91), with the majority of patients (89.7%) being white. Self-reported frequency of NA to diet was 80.4% and to fluid 75.3% in the total sample. The degree of NA to diet and fluid differed significantly, with the US patients (68.1% vs. 61.1%) reporting less NA when compared with German (81.6% vs. 79.0%) patients (p<0.0001). Phosphorus, albumin, IDWG and Kt/V levels were higher in the US compared with the German subsample (all p<0.0001; IDWG p<0.003). Generalized regression models revealed that education (p<0.01) and smoking (p<0.01) predicted NA to diet, whereas single marital status (p<0.008) and male sex (p<0.04) were independent predictors for NA to fluid. NA persists as one of the most challenging tasks in health care of patients with chronic conditions, including hemodialysis patients. Our findings suggest that patient, condition-related, socioeconomic and health care system-related factors may contribute to NA to diet and fluid restrictions.

    Pregnant patients with chronic renal insufficiency treated with hemodialysis experience adverse perinatal results. To compare perinatal complications of patients with chronic renal insufficiency undergoing hemodialysis who become pregnant vs. the complications of women with chronic renal insufficiency not undergoing dialysis but who then require dialysis during gestation. Transversal and retrospective study that included three patients with chronic renal insufficiency on chronic hemodialysis who became pregnant (group A) and three patients with chronic renal insufficiency without hemodialysis at the time of conception but who required dialysis during gestation (group B). Perinatal results were compared. Statistical analysis was performed with measures of central tendency and dispersion and Student t-test. Group A had 25 sessions vs. group B with 29 hemodialysis sessions (p = 0.88). Maternal complications were anemia 100% (six cases), Cesarean delivery 83.3% (group A 2 cases vs. group B 2 cases), preeclampsia 50% (group A 2 cases vs. group B 1 case), uncontrolled hypertension 50% (group A 2 cases vs. group B 1 case), preterm delivery 50% (group A 2 cases vs. group B 1 case), transfusion 33.3% (group A 2 cases), polyhydramnios 33.3% (group A 1 case vs. group B 1 case) and abortion 16.6% (group A 1 case). Fetal complications included fetal loss 16.6% (group A 1 case), neonatal mortality 33.3% (group A 1 cases vs. group B 1 case), prematurity 50% (group A2 cases vs. group B 1 case), fetal distress 50% (group A 1 case vs. group B 2 cases), respiratory failure 33.3% (group A 2 cases) and fetal growth restriction 16.6% (group A 1 case). Frequency of perinatal complications is elevated in both groups.

    There is mounting evidence demonstrating the importance of adequate physical activity to promote better well-being among hemodialysis patients. Available data pertaining to the levels of physical activity and its determinants among hemodialysis patients is, however, scarce in Malaysia. The objectives of this study are hence to determine the levels of physical activity and it associated factors among hemodialysis patients. A total of 70 subjects were recruited from three dialysis centres in Selangor. A face-to-face interview was conducted to obtain socio-demographic data and subjects' knowledge on dietary sources. Medical history, biochemical parameters and weight status were obtained from medical records. Physical activity level (PAL) was assessed using the Global Physical Activity Questionnaire (GPAQ). A total of 81.4% and 18.6% of the respondents had low and moderate PALs, respectively. Thus, none of the respondents had high PAL. Serum creatinine, education level, personal income and knowledge score on potassium-related medical complications were factors found to correlate significantly with PAL. Multiple linear regression analysis showed that higher PAL was predicted by a lower knowledge score on dietary sodium source, higher education and higher serum creatinine. Despite consistent documentation of the potential positive impact of physical exercise on hemodialysis outcomes, the level of physical activity remains low among these patients. It is hoped that these findings can add to the existing body of knowledge and serve as a supporting document for the formulation of appropriate interventions to improve the status of physical activity among hemodialysis patients in Malaysia.

    Hemodialysis patients present with a broad spectrum of specific and nonspecific skin disorders, which rarely coexist. We report an exceptional case of a hemodialysis patient that developed acquired reactive perforating collagenosis and pseudoporphyric bullous dermatosis on the basis of common skin disorders which include hyperpigmentation, pruritus, xerosis cutis, and Linsday's nails. Interestingly, our patient presented with two unusual but distinctive cutaneous dermopathies on the background of other commonly seen skin alterations. The patient was successfully treated with allopurinol and N-acetylcysteine. Avoidance of potentially triggering factors such as alcohol, sunlight exposure and certain medication was recommended. Thus, increasing clinical awareness, assiduous investigation and early treatment of skin disorders are required to improve the prognosis and quality of life in this patient population. © 2016 International Society for Hemodialysis.

    Some β-blockers are efficiently removed from the circulation by hemodialysis (“high dialyzability”) whereas others are not (“low dialyzability”). This characteristic may influence the effectiveness of the β-blockers among patients receiving long-term hemodialysis. To determine whether new use of a high-dialyzability β-blocker compared with a low-dialyzability β-blocker associates with a higher rate of mortality in patients older than age 66 years receiving long-term hemodialysis, we conducted a propensity-matched population-based retrospective cohort study using the linked healthcare databases of Ontario, Canada. The high-dialyzability group (n=3294) included patients initiating atenolol, acebutolol, or metoprolol. The low-dialyzability group (n=3294) included patients initiating bisoprolol or propranolol. Initiation of a high- versus low-dialyzability β-blocker was associated with a higher risk of death in the following 180 days (relative risk, 1.4; 95% confidence interval, 1.1 to 1.8; P<0.01). Supporting this finding, we repeated the primary analysis in a cohort of patients not receiving hemodialysis and found no significant association between dialyzability and the risk of death (relative risk, 1.0; 95% confidence interval, 0.9 to 1.3; P=0.71). β-Blocker exposure was not randomly allocated in this study, so a causal relationship between dialyzability and mortality cannot be determined. However, our findings should raise awareness of this potentially important drug characteristic and prompt further study. PMID:25359874

    Objective Markers of better nutritional status including both higher levels of serum albumin (as a measure of visceral proteins) and creatinine (as a measure of the muscle mass) are associated with lower mortality in conventional (thrice-weekly) hemodialysis patients. However, data for these associations in twice-weekly hemodialysis patients, in whom less frequent hemodialysis may confound nutritional predictors, are lacking. Design, Settings and Subjects We identified 1,113 twice-weekly and matched 4,448 thrice-weekly hemodialysis patients from a large national dialysis cohort of incident hemodialysis patients over 5 years (2007-2011). Mortality risk, adjusted for potential confounders, was examined across two-by-two combinations of serum creatinine (<6 mg/dl vs. ≥6 mg/dl) and albumin (<3.5 g/dl vs. ≥3.5 g/dl) for each treatment frequency yielding a total of eight groups. Results Patients were 70±14 years old and included 48% women, and 55% diabetics. Using the thrice-weekly hemodialysis patients with creatinine≥6mg/dl and albumin≥3.5g/dl as reference, patients with creatinine<6mg/dl and albumin<3.5g/dl had a 1.8-fold higher risk of mortality (HR: 1.75, 95%CI: 1.33-2.30) in twice-weekly and 2.2-fold increased risk of mortality (HR: 2.21, 95%CI: 1.81-2.70) in thrice-weekly hemodialysis patients, respectively in fully adjusted models adjusted for demographics, comorbidities and markers of malnutrition and inflammation. A test for interaction showed there was no significant difference in albumin creatinine mortality associations between twice-weekly and thrice-weekly hemodialysis patients (p-for-interaction 0.7667). Conclusions Surrogate markers of higher visceral protein and muscle mass combined may confer greatest survival in both twice-weekly and thrice-weekly hemodialysis patients. PMID:27528412

    Hemodialysis (HD) patients have been increasing recently. Some rheumatoid arthritis (RA) patients need hemodialysis (HD), though the proportion is not high. At present, such patients are almost treated with corticosteroids and/or nonsteroidal anti-inflammatory drugs alone, even if they have a high disease activity that would require disease-modifying anti-rheumatic drug (DMARD) therapy, partly because the safety of DMARDs in RA patients with end-stage renal disease has not been confirmed. Their joint destruction would be inevitable and lead to impaired activities of daily living. As there are no guidelines for the use of DMARDs in HD patients, here I reviewed the previous reports about the treatment of DMARDs including biologics for patients with RA undergoing HD.

    Background There are scarce epidemiological data on cardiovascular risk profile of chronic hemodialysis patients in Brazil. Objective The CORDIAL study was designed to evaluate cardiovascular risk factors and follow up a hemodialysis population in a Brazilian metropolitan city. Methods All patients undergoing regular hemodialysis for chronic renal failure in all fifteen nephrology centers of Porto Alegre were considered for inclusion in the baseline phase of the CORDIAL study. Clinical, laboratory and demographic data were obtained in medical records and in structured individual interviews performed in all patients by trained researchers. Results A total of 1215 patients were included (97.3% of all hemodialysis patients in the city of Porto Alegre). Their average age was 58.3 years old, 59.5% were male and 62.8% were white. The prevalence of cardiovascular risk factors observed was 87.5% for hypertension, 84.7% for dyslipidemia, 73.1% for sedentary lifestyle, 53.7% for tobacco use, and 35.8% for diabetes. In a multivariate adjusted analysis, we found that sedentary lifestyle (p = 0.032, PR 1.08 - 95%CI: 1.01-1.15), dyslipidemia (p = 0.019, PR 1.08 - 95%CI: 1.01-1.14), and obesity (p < 0.001, PR 1.96 - 95%CI: 1.45-2.63) were more frequent in women; and hypertension (p = 0.018, PR 1.06 - 95%CI: 1.01-1.11) and tobacco use (p = 0.006, PR 2.7 - 95%CI: 1.79-4.17) were more often found among patients under 65 years old. Sedentary lifestyle was independently associated with time in dialysis less than 12 months (p < 0.001, PR 1.23 - 95% CI: 1.14-1.33). Conclusion Hemodialysis patients in this southern metropolitan Brazilian city have a high prevalence of cardiovascular risk factors resembling many northern countries. PMID:24759948

    Tissue accumulation of advanced glycation end products (AGE) is thought to contribute to the progression of cardiovascular disease (CVD). Skin autofluorescence, a non-invasive measure of AGE accumulation using autofluorescence of the skin under ultraviolet light, has been reported to be an independent predictor of mortality associated with CVD in Caucasian patients on chronic hemodialysis. The aim of this study was to assess the predictive value of skin autofluorescence on all-cause and cardiovascular mortality in non-Caucasian (Japanese) patients on chronic hemodialysis. Baseline skin autofluorescence was measured with an autofluorescence reader in 128 non-Caucasian (Japanese) patients on chronic hemodialysis. All-cause and cardiovascular mortality was monitored prospectively during a period of 6 years. During the follow-up period, 42 of the 128 patients died; 19 of those patients died of CVD. Skin autofluorescence did not have a significant effect on all-cause mortality. However, age, carotid artery intima-media thickness (IMT), serum albumin, high-sensitivity C-reactive protein (hsCRP), skin autofluorescence and pre-existing CVD were significantly correlated with cardiovascular mortality. Multivariate Cox regression analysis showed skin autofluorescence (adjusted hazard ratio [HR] 3.97; 95% confidence interval [CI]1.67-9.43), serum albumin (adjusted HR 0.05; 95% CI 0.01-0.32), and hsCRP (adjusted HR 1.55; 95% CI 1.18-2.05) to be independent predictors of cardiovascular mortality. The present study suggests that skin autofluorescence is an independent predictor of cardiovascular mortality in non-Caucasian (Japanese) patients on chronic hemodialysis. © 2014 The Authors.

    Half of patients starting chronic hemodialysis used a transient vascular catheter as a vascular access (unplanned initiation). An objective of the Quality Management Group of the Spanish Society of Nephrology is to achieve that 80% of the patients starting hemodialysis do it with an arteriovenous fistula. We want to review the causes of non-planned hemodialysis nowadays. In 2010, 43 patients had started chronic hemodialysis in the Hospital Ramón y Cajal in Madrid (Spain). Mean age was 61 years, 79% were men, the most frequent cause of chronic renal disease was the diabetes (23%) and Charlson Comorbidity Index was 6.3 ± 2.6. The unplanned hemodialysis occurred in 20 patients (47%), without any differences with the 23 patients who began planned hemodialysis, in none of the clinical or demographic parameters analyzed. The main cause of unplanned hemodialysis was the acute exacerbation of chronic kidney disease stage 3 or 4, previously stable, secondary to an unforeseeable intercurrent process (8 patients, 40% of the cases). One patient began after a non-recovery acute renal failure and in other 6 patients, the reason of unplanned hemodialysis initiation was not attributable to the operation Health System (in 3 cases unknown kidney chronic disease and in the other 3 cases it was patient´s responsibility). Only in 5 cases (25%), the cause could be corrigible. Most causes of unplanned hemodialysis does not come from the healthcare organization and therefore not easy to resolve it. Consequently, the objective of the Quality Group will be difficult to be achieved.

    Little is known about the impact of holiday and other special-event meals on patients with chronic medical conditions. It is possible that patients are less adherent with dietary restrictions during such meals. We sought to determine the impact of Super Bowl parties on nutritional parameters among hemodialysis patients. To determine the relationship between attending a Super Bowl party and subsequent change in serum phosphorus level, serum potassium level, interdialytic weight gain, and blood pressure. Retrospective cohort study. Outpatient dialysis unit. One hundred twenty-two chronic hemodialysis patients. Patients were asked whether they had attended a Super Bowl party. Serum phosphorus level, serum potassium level, interdialytic weight gain, and predialysis blood pressure at the hemodialysis treatment after the Super Bowl and at the hemodialysis treatment 1 month previously were obtained by chart abstraction. The 15 patients who had attended a party had increased serum phosphorus levels (+0.5 mg/dL) and interdialytic weight gain (+1.1% of dry weight) from baseline. These increases were statistically significant (P values .005 and .02, respectively) compared with patients who did not attend a party. Attendees also had increased systolic blood pressure (+6 mm Hg) from baseline, but this was of marginal statistical significance compared with nonattendees (P = .14). Attending a party was not significantly associated with changes in serum potassium and diastolic blood pressure. Attending a Super Bowl party is associated with adverse changes in several nutritional parameters. Although patients should not be discouraged from attending holiday and special-event meals, management of hemodialysis patients should include increased dietary counseling before holidays and special events and increased monitoring afterward.

    Abstract We analyzed the levels of endotoxin and β-d-glucan, which possibly induce cytokine production, in the synovial fluid of patients on long-term hemodialysis and compared the results to those in patients with osteoarthritis and rheumatoid arthritis. We studied 42 knees in 42 hemodialysis patients, 21 in 21 osteoarthritis patients, and 26 in 26 rheumatoid arthritis patients. The mean ages were 60.7, 63.2, and 59.7 years, respectively. The duration of hemodialysis in the long-term hemodialysis group averaged 14.0 years. The concentrations of endotoxin and β-d-glucan in the synovial fluid of these three groups were measured. The concentration of endotoxin was the same in the three groups. However, the concentration of β-d-glucan was significantly higher in long-term hemodialysis patients. This finding suggests that β-d-glucan may have some relation to the pathogenesis of the synovitis which exists in the hydrarthrosis of long-term hemodialysis patients.

    Patients value health-related quality of life (HRQOL) over survival. It was our aim to study the relation between attainment of widely accepted performance targets and HRQOL in hemodialysis patients. This study included baseline data from 715 hemodialysis patients from 29 dialysis centers. Six clinical performance targets, as recommended by the Kidney Disease Outcomes Quality Initiative (KDOQI), were evaluated: single-pool Kt/V (≥1.2), hemoglobin (11-13 g/dl), vascular access (fistula), phosphorus (2.3-4.5 mg/dl), parathyroid hormone (150-300 pg/ml), and blood pressure (predialysis <140/90 and postdialysis <130/ 80 mm Hg). After correction for case-mix and multiple comparisons, no association was found between the 6 KDOQI clinical performance targets and the 14 HRQOL domains, or between the number of performance targets reached and HRQOL. Attainment with widely accepted clinical performance targets was not related to the HRQOL of hemodialysis patients. Hence, in clinical guidelines, HRQOL should be adopted as an explicit treatment goal for these individuals. Copyright © 2011 S. Karger AG, Basel.

    The multiple dietary restrictions recommended to hemodialysis patients may be difficult to achieve and, at the same time, may result in nutritional deficiencies rendering a poor dietary quality. We here assess the dietary quality and adherence to renal-specific guideline recommendations among hemodialysis patients from a single center in Canary Islands, Spain. Cross-sectional study, including 91 patients undergoing maintenance hemodialysis. Clinical data and 3-day dietary records were collected. We compared patient's reported nutrients intake with guideline recommendations. We also evaluated their alignment with current American Heart Association dietary guidelines for cardiovascular prevention. Seventy-seven percent and 50% of patients consumed less than the recommended daily energy and protein, respectively. Although half of the patients met the recommendations for dietary fat intake, this was accounted by an excess of saturated fat in 92% of them. Only 22% consumed sufficient fiber. A very small proportion of patients (less than 50%) met the requirements for vitamins and other micronutrients. Insufficient dietary intake was observed in most patients for all vitamins except for cobalamin. Similarly, inadequate dietary intake was observed for many minerals, by both excess (phosphorus, calcium, sodium, and potassium) and defect (magnesium). Most patients met the recommendations for iron and zinc in their diets. A large proportion of hemodialysis patients at our center did not meet current renal-specific dietary recommendations. The quality of the diet was considered poor and proatherogenic according to American Heart Association guidelines. Copyright © 2016 National Kidney Foundation, Inc. Published by Elsevier Inc.

    Headache is one of the most frequently encountered neurological symptoms during hemodialysis. According to International Classification of Headache criteria dialysis-related headache was defined as the headache occurring during hemodialysis with no specific characteristic. It resolves spontaneously within 72 hours after the hemodialysis session ends. There are few studies in the literature investigating the clinical features of dialysis headache. The pathophysiology of hemodialysis-related headache is not known, but various triggering factors have been identified, including changes in blood pressure, serum sodium and magnesium levels during hemodialysis sessions, caffeine deprivation and stress. The aim of this article is to evaluate and analyze features of headache in patients undergoing hemodialysis. © 2014 International Society for Hemodialysis.

    To explore the effects of etiological classification and the distance between residence and hemodialysis unit on cardiovascular complications and treatments in maintenance hemodialysis (MHD) patients. A total of 756 MHD patients were collected from 12 hemodialysis centers of Guiyang, China between January 2011 and May 2012. Their distribution characteristics and correlations were based on medical records. And statistical analyses were performed. The ratio of males and females was 1.45: 1. And their mean age was (49.1 ± 14.7) years old. And 496 (65.6%) cases suffered from cardiovascular complications. The analysis of multi-factor Logistic regression revealed that distance between residence and dialysis unit was an independent risk factor of cardiovascular complications. The group of the farthest distance ( > 30 km) had the worst influence on dialysis adequacy Kt/V score, urea clearance rate, dialysis frequency and time per week. And the levels of blood phosphorus, triglyceride and cholesterol in the fourth group had marked elevations. It had a significant positive correlation with distance (P < 0.05). The distance between residence and dialysis unit is an independent risk factor of cardiovascular complications in MHD patients. The farthest distance ( > 30 km) has the greatest influence on dialysis adequacy.

    Several studies have shown that non-adherence is a common and increasing problem among individuals with chronic illnesses, including hemodialysis patients. The present study aimed to investigate the influence of depression and health cognitions on medication adherence among patients undergoing hemodialysis. A sample of 168 participants was recruited from six general hospitals in the broader area of Athens, consisting of patients undergoing in-center hemodialysis. Measurements were conducted with the following instruments: the Medication Adherence Rating Scale, the Center for Epidemiologic Studies Depression Scale (CES-D), and the Multidimensional Health Locus of Control (MHLC) scale. The results indicated that medication adherence was associated positively with the dimensions of internal and doctor-attributed health locus of control, measured by the MHLC. It was also related negatively to depression, measured by the CES-D. The present study demonstrates the importance of depression in understanding the medication adherence of hemodialysis patients, as well as the contribution of heath cognitions.

    Magnesium concentration is a proven predictor of mortality in hemodialysis patients. Recent reports have indicated that proton pump inhibitor (PPI) use affects serum magnesium levels, however few studies have investigated the relationship between PPI use and magnesium levels in hemodialysis patients. This study aimed to clarify the association between PPI use and serum magnesium levels in hemodialysis patients. We designed this cross sectional study and included 1189 hemodialysis patients in stable condition. Associations between PPI and magnesium-related factors, as well as other possible confounders, were evaluated using a multiple regression model. We defined hypomagnesemia as a value < 2.0 mg/dL, and created comparable logistic regression models to assess the association between PPI use and hypomagnesemia. PPI use is associated with a significantly lower mean serum magnesium level than histamine 2 (H2) receptor antagonists or no acid-suppressive medications (mean [SD] PPI: 2.52 [0.45] mg/dL; H2 receptor antagonist: 2.68 [0.41] mg/dL; no acid suppressive medications: 2.68 [0.46] mg/dL; P = 0.001). Hypomagnesemia remained significantly associated with PPI (adjusted OR, OR: 2.05; 95% CI: 1.14–3.69; P = 0.017). PPI use is associated with an increased risk of hypomagnesemia in hemodialysis patients. Future prospective studies are needed to explore magnesium replacement in PPI users on hemodialysis.

    Cognitive impairment in hemodialysis patients is common and associated with adverse outcomes. So far, the underlying pathogenesis remains unclear. Therefore, we examined the potential relationship between cognitive impairment and three different categories of risk factors with particular focus on arterial stiffness measured by pulse wave velocity (PWV). A total of 201 chronic hemodialysis patients underwent cognitive testing under standardized conditions using the Montreal Cognitive Assessment (MoCA). Demographic data including cardiovascular risk factors, dialysis-associated factors as well as factors related to chronic kidney disease (CKD) were analyzed. To account for arterial stiffness, PWV was measured by ambulatory blood pressure monitoried with an oscillometric device that records brachial blood pressure along with pulse waves. In our cohort, 60.2% of patients showed pathological MoCA test results indicating cognitive impairment. PWV was significantly associated with cognitive impairment apart from age, educational level, diabetes, and hypercholesterolemia. High prevalence of cognitive impairment in hemodialysis patients was confirmed. For the first time, an association between cognitive impairment and arterial stiffness was detected in a larger cohort of hemodialysis patients. Concerning the underlying pathogenesis of cognitive impairment, current results revealed a potential involvement of arterial stiffness, which has to be further evaluated in future studies. © 2017 The Author(s).

    Patients with end-stage renal disease commonly visit the emergency department (ED). The purpose of this investigation is to examine the prevalence of baseline abnormal lactate levels and to evaluate the effects of hemodialysis on serum lactate levels. This was a prospective observational cohort study performed at an outpatient dialysis facility at an urban tertiary care hospital. The study consisted of 226 patients with end-stage renal disease who were receiving long-term hemodialysis and were enrolled during a 2-day period at the beginning of December 2015. Blood drawn for lactate levels was immediately analyzed before and after hemodialysis sessions. All patients completed their hemodialysis sessions. The prevalence of an abnormal lactate level (greater than 1.8 mmol/L) before hemodialysis was 17.7% (n=40). Overall, lactate levels decreased by 27% (SD 35%) after hemodialysis, with a decrease of 37% (SD 31%) for subgroups with a lactate level of 1.9 to 2.4 mmol/L, and 62% (SD 14%) with a lactate of 2.5 to 3.9 mmol/L. The data presented help providers understand the prevalence of abnormal lactate values in an outpatient end-stage renal disease population. After hemodialysis, lactate levels decreased significantly. This information may help medical providers interpret lactate values when patients with end-stage renal disease present to the ED. Copyright © 2017 American College of Emergency Physicians.

    The assessment of self-esteem in hemodialysis people is becoming increasingly important and necessary. Low self-esteem as a problem in patients undergoing hemodialysis decreases adherence to treatment. The researcher intends to carry out a study in order to investigate the effect of self-care education on enhancement of the self-esteem of patients undergoing hemodialysis in Iran. This is a quasi-experimental study. The subjects of the study who were selected based on purposive sampling method consisted of 50 patients with advanced chronic renal disease treated with hemodialysis. Before the intervention, two questionnaires were completed by patients. There was no intervention in the control group and the patients received only routine care in the hospital. In the experimental group, the hemodialysis patients received 5 consecutive one-hour training sessions by the researcher. Then the Rosenberg scale was filled out by the patients 2 month later. According to the results, Paired t-test showed a significant difference between the mean self-esteem score in both groups before and after intervention. Increasing the knowledge and awareness of hemodialysis patients must constitute a cornerstone of therapy and an integral part of nursing responsibilities. Nurses should educate the patients about self-care behaviors and remind them of the dangerous complications of abandoning these.

    In hemodialysis patients, free amino acids and alpha-ketoacids in plasma were determined by fluorescence HPLC to assess the effect of alpha-ketoglutarate administration in combination with the phosphate binder calcium carbonate on the amino acid metabolism. During 1 year of therapy in parallel to inorganic phosphate, urea in plasma decreased significantly, histidine, arginine and proline as well as branched chain alpha-ketoacids, in particular alpha-ketoisocaproate, a regulator of protein metabolism, increased. Thus, administration of alpha-ketoglutarate with calcium carbonate effectively improves amino acid metabolism in hemodialysis patients as it decreases hyperphosphatemia.

    It is unclear whether warfarin is protective or harmful in patients with ESRD and atrial fibrillation. This state of equipoise raises the question of whether alternative anticoagulants may have a therapeutic role. We aimed to determine apixaban pharmacokinetics at steady state in patients on hemodialysis. Seven patients received apixaban 2.5 mg twice daily for 8 days. Blood samples were collected before and after apixaban administration on days 1 and 8 (nondialysis days). Significant accumulation of the drug was observed between days 1 and 8 with the 2.5-mg dose. The area under the concentration-time curve from 0 to 24 hours increased from 628 to 2054 ng h/ml ( P <0.001). Trough levels increased from 45 to 132 ng/ml ( P <0.001). On day 9, after a 2.5-mg dose, apixaban levels were monitored hourly during dialysis. Only 4% of the drug was removed. After a 5-day washout period, five patients received 5 mg apixaban twice daily for 8 days. The area under the concentration-time curve further increased to 6045 ng h/ml ( P =0.03), and trough levels increased to 218 ng/ml ( P =0.03), above the 90th percentile for the 5-mg dose in patients with preserved renal function. Apixaban 2.5 mg twice daily in patients on hemodialysis resulted in drug exposure comparable with that of the standard dose (5 mg twice daily) in patients with preserved renal function and might be a reasonable alternative to warfarin for stroke prevention in patients on dialysis. Apixaban 5 mg twice daily led to supratherapeutic levels in patients on hemodialysis and should be avoided. Copyright © 2017 by the American Society of Nephrology.

    Are occurrences of vascular access thrombosis and hospitalization higher in hemodialysis patients with hematocrits (Hcts) > 36% compared to those < 36%? This 12-month retrospective study included 30 male hemodialysis patients who received erythropoietin (rHuEPO) for at least 6 months. Sixty percent (n = 18) had arteriovenous fistulas and 40% (n = 12) had polytetrafluoroethylene grafts. The mean age was 59.6 years. Twenty patients during 216 patient months had a mean Hct < 36% with five thromboses (2.3%). Ten patients during 118 patient months had a mean Hct > 36% with four thromboses (3.4%). There was no statistically significant difference between the thrombosis rates in the two groups. There were four hospitalizations in 118 patient months in the > 36% group (3.4%). There were 33 hospitalizations in 216 patient months in the < 36% group (15.3%). This is 4.5 times higher than the > 36% group. Our data suggest that Hcts > 36% are not associated with increased thrombosis and are associated with lower hospitalization rates.

    The risk of acute pancreatitis in patients on long-term peritoneal dialysis is higher as compared to the general population. However, the relationship between long-term hemodialysis and acute pancreatitis has never been established. We investigated the incidence of acute pancreatitis among patients on long-term hemodialysis in Taiwan to evaluate if there is a higher risk of acute pancreatitis in comparison to the general population. We utilized a National Health Insurance (NHI) claims data sample containing one million beneficiaries. We followed all adult beneficiaries from January 1, 2007 until December 31, 2010 to see if they had been hospitalized for acute pancreatitis during this period. We further identified patients on chronic hemodialysis and compared their risk of acute pancreatitis with the general population. This study included 2603 patients with long-term hemodialysis and 773,140 patients without hemodialysis. After controlling for age, gender, Charlson Comorbidity Index Score, geographic region, socioeconomic status and urbanization level, the adjusted hazard ratio was 3.44 (95% Confidence interval, 2.5-4.7). The risk of acute pancreatitis in patients on long-term hemodialysis is significantly higher in comparison to the general population.

    Endothelial dysfunction is often found in both hyperuricemia and hemodialysis patients. Recent studies have shown that treating hyperuricemia with allopurinol improves endothelial dysfunction. This study is performed to assess the effect of febuxostat on endothelial dysfunction in hemodialysis patients with hyperuricemia. We randomly assigned 53 hemodialysis patients with hyperuricemia to a febuxostat (10 mg daily) group and a control group and measured flow-mediated dilation, serum uric acid (UA) levels, systolic and diastolic blood pressure, malondialdehyde-modified low-density lipoprotein (MDA-LDL), and highly sensitive C-reactive protein (hsCRP) at baseline and at the end of a 4-week study period. Flow-mediated dilation increased from 5.3% ± 2.4% to 8.9% ± 3.6% in the febuxostat group but did not change significantly in the control group. Treatment with febuxostat resulted in a significant decrease in serum UA level and a significant decrease in MDA-LDL compared with baseline, but no significant difference was observed in hsCRP level or blood pressure. No significant differences were observed in the control group. Febuxostat improved endothelial dysfunction and reduced serum UA levels and oxidative stress in hemodialysis patients with hyperuricemia. © 2015 International Society for Hemodialysis.

    Resilience and religiosity have received attention as an important process in the experience and management of chronic comorbidities; however, there is no study evaluating resilience in hemodialysis patients and its association with other psychological dimensions or with treatment adherence. This observational prospective study assessed resilience (25 item Wagnild and Young Resilience Scale), religiosity under three dimensions (organizational, non-organizational and intrinsic) using DUREL scale, depressive symptoms (Patient Health Questionnaire-9) and health-related quality of life (Short Form-36 questionnaire). The main outcomes were medication adherence using the Morisky Medication Adherence Scale-8 (MMAR-8) and the missing/shortened dialysis sessions in the following six months. Of 208 patients approached, 202 (97.1%) agreed to participate. One hundred twenty-three patients (60.9%) were males and mean age was 52.8 ± 14.8 years-old. The median time on hemodialysis was 36 months (IQR, 12, 84). 82 (40.6%) patients obtained a MMAS-8 score <6 and were considered as having 'poor adherence'. Overall, the mean score of medication adherence was low (5.7 ± 2.1). About adherence to hemodialysis sessions, patients missed a total of 234 (1.6%) hemodialysis sessions. Forty-eight patients (23.7%) missed an average of at least three sessions in six months. Regarding adherence to medication, there was no association in the uni- or multivariate analysis between religiosity dimensions and MMAS-8 score. After adjustment, resilience was positively associated with MMAS-8 score (standardized β coefficient .239, p = .016). Organized and intrinsic religiosity were associated with adherence to dialysis sessions (standardized β coefficient .258, p = .004 and .231, p = .026, respectively). Interestingly, opposite to medication adherence, more resilient patients were associated with less adherence to hemodialysis sessions (standardized β coefficient -.296, p = .001

    Both dialysis dose and residual kidney function (RKF) contribute to solute clearance and are associated with outcomes in hemodialysis patients. We hypothesized that the association between dialysis dose and mortality is attenuated with greater RKF. Among 32 251 incident hemodialysis patients in a large US dialysis organization (2007-11), we examined the interaction between single-pool Kt/V (spKt/V) and renal urea clearance (rCLurea) levels in survival analyses using multivariable Cox proportional hazards regression model. The median rCLurea and mean baseline spKt/V were 3.06 [interquartile range (IQR) 1.74-4.85] mL/min/1.73 m2 and 1.32 ± 0.28, respectively. A total of 7444 (23%) patients died during the median follow-up of 1.2 years (IQR 0.5-2.2 years) with an incidence of 15.4 deaths per 100 patient-years. The Cox model with adjustment for case-mix and laboratory variables showed that rCLurea modified the association between spKt/V and mortality (Pinteraction = 0.03); lower spKt/V was associated with higher mortality among patients with low rCLurea (i.e. <3  mL/min/1.73 m2) but not among those with higher rCLurea. The adjusted mortality hazard ratios (aHRs) and 95% confidence intervals of the low (<1.2) versus high (≥1.2) spKt/V were 1.40 (1.12-1.74), 1.21 (1.10-1.33), 1.06 (0.98-1.14), and 1.00 (0.93-1.08) for patients with rCLurea of 0.0, 1.0, 3.0 and 6.0 mL/min/1.73 m2, respectively. Incident hemodialysis patients with substantial RKF do not exhibit the expected better survival at higher hemodialysis doses. RKF levels should be taken into account when deciding on the dose of dialysis treatment among incident hemodialysis patients.

    This study aimed to assess the effectiveness of Benson's relaxation technique in improving the hemodialysis patients' dietary and fluid adherence and biomedical markers. This randomized controlled trial with a pre-post test design was conducted on 86 hemodialysis patients randomly divided into an intervention (receiving Benson's relaxation technique) and a control group (usual care). The setting of the study was two hemodialysis units affiliated to Shiraz University of Medical Sciences, Shiraz, Iran. The patients listened to the audiotape of Benson's relaxation technique twice a day each time for 20min for 8 weeks. Dietary and fluid adherence and some biomedical markers were measured in both the intervention and the control group at baseline and at the 8th week after the intervention. The results showed significant differences between the two groups regarding blood urea nitrogen and phosphate as dietary adherence and interdialytic weight gain as fluid adherence in the 8th week of the intervention (P<0.05). Also, a significant difference was found between the two groups concerning blood glucose level after the intervention (P<0.05). This study highlighted the importance of Benson's relaxation technique in improvement of adherence and some biomedical markers in hemodialysis patients. Thus, Benson's relaxation therapy could be used as a part of the nursing care practice for hemodialysis patients and those suffering from chronic diseases. Copyright © 2014 Elsevier Ltd.

    Patients starting dialysis often have substantial residual kidney function. Incremental hemodialysis provides a hemodialysis prescription that supplements patients' residual kidney function while maintaining total (residual + dialysis) urea clearance (standard Kt/Vurea) targets. We describe our experience with incremental hemodialysis in patients using NxStage System One for home hemodialysis. From 2011 to 2015, we initiated 5 incident hemodialysis patients on an incremental home hemodialysis regimen. The biochemical parameters of all patients remained stable on the incremental hemodialysis regimen and they consistently achieved standard Kt/Vurea targets. Of the two patients with follow-up >6 months, residual kidney function was preserved for ≥2 years. Importantly, the patients were able to transition to home hemodialysis without automatically requiring 5 sessions per week at the outset and gradually increased the number of treatments and/or dialysate volume as the residual kidney function declined. An incremental home hemodialysis regimen can be safely prescribed and may improve acceptability of home hemodialysis. Reducing hemodialysis frequency by even one treatment per week can reduce the number of fistula or graft cannulations or catheter connections by >100 per year, an important consideration for patient well-being, access longevity, and access-related infections. The incremental hemodialysis approach, supported by national guidelines, can be considered for all home hemodialysis patients with residual kidney function.

    Toxoplasmosis is a worldwide distributed parasitic disease with wide range of complications in immunocompromised patients. This systematic review and meta-analysis study was performed to evaluate the seroprevalence of Toxoplasma gondii (T. gondii) among patients undergoing hemodialysis patients in Iran. We searched the English and Persian databases for studies reporting T. gondii seroprevalence in Iranian hemodialysis patients up to 31 December 2017. Inclusion and exclusion criteria were applied. A total of 10 studies containing 1865 participants (1048 patients and 817 controls) met the eligibility criteria. T. gondii antibodies were reported in 58% (95% CI, 46-70) vs. 40% (95% CI, 31-50) and 2% (95% CI, 0-6) vs. 0.0% (95% CI, 0-1) for the IgG and IgM among hemodialysis patients and healthy controls, respectively. Based on meta-analysis. hemodialysis patients were significantly more likely to be seropositive for IgG- (OR = 2.04; 95% CI = 1.54-2.7; P < 0.001) and IgM- (OR = 2.53; 95% CI = 1.23-5.22; P < 0.001) antibodies against T. gondii infection compared to healthy individuals. The current study revealed a high prevalence of T. gondii infection in hemodialysis patients. Since hemodialysis patients are immunocompromised and T. gondii can cause serious clinical complications, we recommend that T. gondii infection screening and periodic repetition should be incorporated into the routine clinical care of these patients.

    Background Intra-dialytic hypertension (IDH) is emerging as an important issue in hemodialysis patients. Its risk factors and clinical outcomes are unclear. Methods A total of 73 prevalent hemodialysis patients were enrolled. They included 14 (19.2%) patients with baseline IDH and 59 patients without IDH. Their clinical parameters, laboratory parameters, and mortality were investigated over 78 months. Results The risks factor of IDH included low serum potassium levels, low ultrafiltration, and low arm muscle area. Lower median survival was evident in the IDH group compared to the non-IDH group, but was not significantly different. After adjusting for relevant confounders for age, the IDH group displayed 2.846 times higher mortality rate than the non-IDH Group (adjusted hazard ratio: 2.846; 95% confidence interval: 1.081–7.490; P = 0.034). Conclusion IDH is associated with high mortality in hemodialysis patients. Clinicians should be aware of the risk factors. Future research studies are needed to explore the mechanisms involved in the association between IDH and mortality. PMID:28742805

    The vast majority of maintenance dialysis patients suffer from poor long-term survival rates and lower levels of health-related quality of life. However, home hemodialysis is a historically significant dialysis modality that has been associated with favorable outcomes as well as greater patient autonomy and control, yet only represents a small minority of the total dialysis performed in the United States. Some potential disadvantages of home hemodialysis include vascular access complications, infection-related hospitalizations, patient fatigue, and attrition. In addition, current barriers and challenges in expanding the utilization of this modality include limited patient and provider education and technical expertise. Here we report a 65-year old male with end-stage renal disease due to Alport's syndrome who has undergone 35 years of uninterrupted thrice-weekly home hemodialysis (ie, every Sunday, Tuesday, and Thursday evening, each session lasting 3 to 3¼ hours in length) using a conventional hemodialysis machine who has maintained a high functional status allowing him to work 6-8 hours per day. The patient has been able to liberalize his dietary and fluid intake while only requiring 3-4 liters of ultrafiltration per treatment, despite having absence of residual kidney function. Through this case of extraordinary longevity and outcomes after 35 years of dialysis and a review of the literature, we illustrate the history of home hemodialysis, its significant clinical and psychosocial advantages, as well as the barriers that hinder its widespread adaptation. © 2017 Wiley Periodicals, Inc.

    Obesity has been considered the key in metabolic syndrome (MetS) development, and fat accumulation may be responsible for the occurrence of metabolic abnormalities in hemodialysis patients. The use of gold-standard methods to evaluate obesity is limited, and anthropometric measures may be the simplest methods. However, no study has investigated the association between anthropometric indexes and MetS in these patients. Therefore, the aim was to determine which anthropometric indexes had the best association and prediction for MetS in patients undergoing hemodialysis. Cross-sectional study that included patients older than 18 years, undergoing hemodialysis for at least 3 months. Patients with liver disease and cancer or those receiving corticosteroids or antiretroviral therapy were excluded. Diagnostic criteria from Harmonizing Metabolic Syndrome were used for the diagnosis of MetS. Anthropometric indexes evaluated were body mass index (BMI); percent standard of triceps skinfold thickness and of middle arm muscle circumference; waist circumference (WC); sagittal abdominal diameter; neck circumference; waist-to-hip, waist-to-thigh, and waist-to-height ratios; sagittal index; conicity index; and body fat percentage. Ninety-eight patients were included, 54.1% male, and mean age was 57.8 ± 12.9 years. The prevalence of MetS was 74.5%. Individuals with MetS had increased accumulation of abdominal fat and general obesity. Waist-to-height ratio was the variable independently associated with MetS diagnosis (odds ratio, 1.21; 95% confidence interval, 1.09-1.34; P < .01) and that better predicts MetS, followed by WC and BMI (area under the curve of 0.840, 0.836, and 0.798, respectively, P < .01). Waist-to-height ratio was the best anthropometric predictor of MetS in maintenance hemodialysis patients. © 2015 American Society for Parenteral and Enteral Nutrition.

  10. Reversed association between aldosterone and mortality in hemodialysis patients: Role of volume overload.

    The role of aldosterone has expanded from its genomic effects that involve renal sodium transport to nongenomic effects such as cardiac and renal fibrosis. Elevated aldosterone levels are associated with increased mortality in the general population. However, the association is reversed in patients with end-stage renal disease on maintenance hemodialysis. We have shown that the inverse association between aldosterone and mortality in hemodialysis patients is due to the confounding effect of volume overload. Volume overload, which is prevalent in patients with chronic kidney disease, is associated with both lower aldosterone concentrations and higher mortality. Our findings support salt and water restriction and treatment of hyperaldosteronemia in hemodialysis patients who have achieved strict volume control. Copyright © 2016 Elsevier Inc.

    Background: Chronic renal disease is a health problem in today’s world. In the end-stages of renal disease patients depend upon alternative therapies including dialysis for their survival. However, dialysis causes several stressors on physical, mental and social performance of patients. The present study aimed to review and compare the self-concept in patients undergoing hemodialysis and peritoneal dialysis. Materials and Methods: This was a case-control study including two groups of patients, undergoing hemodialysis and peritoneal dialysis, who referred to Al-Zahra and Ali Asghar Hospitals, which are affiliated to Isfahan University of Medical Sciences. These groups were compared to the control group. Data were collected through completing the form of demographic characteristics and a questionnaire, written by the researcher, pertaining to the self-concept which was collected by the samples. The data were analyzed by the Software SPSS version 18. Findings: ANOVA (analysis of variance) showed that statistically there was a significant difference between mean score of self-concept in the three physical (body-image), psychological, and social self aspects in the two groups of hemodialysis and peritoneal dialysis with the control group; however, Duncan’s post-hoc analysis showed no significant difference between mean score of self-concept in the three mentioned aspects in the two groups of hemodialysis and peritoneal dialysis. Furthermore, ANOVA (analysis of variance) showed that there was no significant difference between mean score of the spiritual aspect of the self-concept in the two groups of hemodialysis and peritoneal dialysis with the control group. Duncan’s post-hoc analysis also showed no significant difference in this aspect between the two groups of hemodialysis and peritoneal dialysis. Conclusions: Patients undergoing dialysis have many psychological disorders and the type of dialysis is not of much importance in this regard; therefore, adequate

    Rheumatoid arthritis (RA) is an autoimmune disorder characterized by progressive joint destruction that requires aggressive treatment using appropriate disease-modifying antirheumatic drugs (DMARDs). RA patients with renal failure, however, are intolerant to most DMARDs due to the potential toxicity. In Japan, tacrolimus was approved for the treatment of RA in 2005. Based on its pharmacokinetics, tacrolimus may be administered to the patients undergoing hemodialysis.

    Background Maintenance hemodialysis is typically prescribed thrice-weekly irrespective of patient's residual kidney function (RKF). We hypothesized that a less frequent schedule at hemodialysis initiation is associated with greater preservation of RKF without compromising survival among patients with substantial RKF. Study Design A longitudinal cohort Setting & Participants 23,645 patients who initiated maintenance hemodialysis in a large dialysis organization in the United States (1/2007–12/2010), who had available RKF data during the first 91 days (or quarter) of dialysis, and who survived the first year. Predictor Incremental (routine twice-weekly for >6 continuous weeks during the first 91 days upon transition to dialysis) versus conventional (thrice-weekly) hemodialysis regimens during the same time. Outcomes Changes in renal urea clearance (KRU) and urine volume (UV) during one year after the first quarter, and survival after the first year. Results Among 23,645 included patients, 51% had substantial KRU (≥3.0 mL/min/1.73m2) at baseline. Compared to 8,068 patients with conventional hemodialysis regimen matched based on baseline KRU, UV, age, gender, diabetes, and central venous catheter use, 351 patients with incremental regimen exhibited 16% (95% CI, 5%-28%) and 15% (95% CI, 2%-30%) more preserved KRU and UV at second quarter, respectively, which remained across the following quarters. Incremental regimen showed higher mortality risk in patients with inadequate baseline KRU (≤3.0 mL/min/1.73m2; HR, 1.61; 95% CI, 1.07-2.44), but not in those with higher baseline KRU (HR, 0.99; 95% CI, 0.76-1.28). Results were similar in subgroup defined by baseline UV of 600 mL/day. Limitations Potential selection bias and wide CIs. Conclusions Among incident hemodialysis patients with substantial RKF, incremental hemodialysis may be a safe treatment regimen and associated with greater preservation of RKF while higher mortality is observed after a year in those with

    Serum indoxyl sulfate (IS; a uremic toxin) levels, which are significantly higher in patients with chronic kidney disease, including those undergoing hemodialysis, than in the robust, are associated with both cardiovascular disease (CVD) and CVD-related mortality. Furthermore, coronary artery calcium (CAC) is an independent predictor of cardiovascular events in patients undergoing hemodialysis. This study aimed to interpret the association between serum IS levels and coronary plaque burden (CPB) or CAC.A total of 30 consecutive patients on hemodialysis, who underwent 320-row coronary multidetector computed tomography (MDCT) angiography for suspected coronary artery disease, were enrolled in this prospective study. Coronary artery percent atheroma volume (a CPB marker) and percent calcium volume (a CAC marker) assessed using MDCT were evaluated. Furthermore, various oxidative and inflammatory markers typified by serum IS levels at a dialysis-free day were measured. Using these data, we investigated correlation between the inflammatory marker IS and CPB or CAC.Multivariable analysis indicated that serum IS levels were positively correlated with CAC [partial regression coefficient, 2.89; 95% confidence interval (CI), 0.35-5.43; P = 0.03] but not with CPB, even after adjustment for cofounders. Composite cardiovascular events, namely, as all-cause death, non-fatal myocardial infarction, disabling stroke, and hospital admission for other cardiovascular events, were reported to be 50% in all patients (95% CI, 32.1-67.9).In patients undergoing hemodialysis, serum IS levels were significantly associated with CAC but not with CPB.

    Extended-hours hemodialysis offers substantially longer treatment time compared to conventional hemodialysis schedules and is associated with improved fluid and electrolyte control and favorable cardiac remodeling. However, whether extended-hours hemodialysis improves survival remains unclear. Therefore, we determined the association between extended-hours compared to conventional hemodialysis and the risk of all-cause mortality in a nationally representative cohort of patients initiating maintenance dialysis in the United States from 2007 to 2011. Survival analyses using causal inference modeling with marginal structural models were performed to compare mortality risk among 1206 individuals undergoing thrice weekly extended-hours hemodialysis or 111,707 patients receiving conventional hemodialysis treatments. The average treatment time per session for extended-hours hemodialysis was 399 minutes compared to 211 minutes for conventional therapy. The crude mortality rate with extended-hours hemodialysis was 6.4 deaths per 100 patient-years compared with 14.7 deaths per 100 patient-years for conventional hemodialysis. In the primary analysis, patients treated with extended-hours hemodialysis had a 33% lower adjusted risk of death compared to those who were treated with a conventional regimen (95% confidence interval: 7% to 51%). Additional analyses accounting for analytical assumptions regarding exposure and outcome, facility-level confounders, and prior modality history were similar. Thus, in this large nationally representative cohort, treatment with extended-hours hemodialysis was associated with a lower risk for mortality compared to treatment with conventional in-center therapy. Adequately powered randomized clinical trials comparing extended-hours to conventional hemodialysis are required to confirm these findings. Copyright © 2016 International Society of Nephrology.

    Elevated aldosterone is associated with increased mortality in the general population. In patients on dialysis, however, the association is reversed. This paradox may be explained by volume overload, which is associated with lower aldosterone and higher mortality. We evaluated the relationship between aldosterone and outcomes in a prospective cohort of 328 hemodialysis patients stratified by the presence or absence of volume overload (defined as extracellular water/total body water >48%, as measured with bioimpedance). Baseline plasma aldosterone was measured before dialysis and categorized as low (<140 pg/mL), middle (140 to 280 pg/mL) and high (>280 pg/mL). Overall, 36% (n = 119) of the hemodialysis patients had evidence of volume overload. Baseline aldosterone was significantly lower in the presence of volume overload than in its absence. During a median follow-up of 54 months, 83 deaths and 70 cardiovascular events occurred. Cox multivariate analysis showed that by using the low aldosterone as the reference, high aldosterone was inversely associated with decreased hazard ratios for mortality (0.49; 95% confidence interval, 0.25-0.76) and first cardiovascular event (0.70; 95% confidence interval, 0.33-0.78) in the presence of volume overload. In contrast, high aldosterone was associated with an increased risk for mortality (1.97; 95% confidence interval, 1.69-3.75) and first cardiovascular event (2.01; 95% confidence interval, 1.28-4.15) in the absence of volume overload. The inverse association of aldosterone with adverse outcomes in hemodialysis patients is due to the confounding effect of volume overload. These findings support treatment of hyperaldosteronemia in hemodialysis patients who have achieved strict volume control.

    Vascular calcification, which involves an active cellular transformation of vascular smooth muscle cells into bone forming cells, is prevalent and predicts mortality in dialysis patients. Its mechanisms are complex and unclear. We presume that irisin, a newly identified myokine also may play roles in vascular calcification in hemodialysis patients. This study aims to evaluate serum irisin levels and establish their relation to vascular calcification and other parameters in hemodialysis patients. A total of 150 patients on maintenance hemodialysis treatment and 38 age- and sex-matched healthy controls were enrolled in this cross-sectional study. Serum irisin concentrations were measured by ELISA. Vascular calcification was evaluated by abdominal aortic calcification scores. Serum irisin concentrations were significantly lower in hemodialysis patients than in controls [52.8 (22.0, 100.0) vs. 460.8 (434.8, 483.4) ng/ml, P<0.01]. In addition, irisin was negatively correlated with the parathyroid hormone level (P=0.01). The HD patients with vascular calcification showed significantly lower serum irisin concentrations [39.0 (21.7, 86.2) vs.79.0 (39.5, 130.2) ng/mL, P<0.01]. Compared with the group without vascular calcification multivariate logistic regression analyses revealed that serum irisin, HD vintage and age were significant independent determinant factors for vascular calcification in HD patients. Our results are the first to provide a clinical evidence of the association between serum irisin and vascular calcification in HD patients. Lower irisin levels, long-term hemodialysis and old ages are independent risk factors in HD patients. © 2018 The Author(s). Published by S. Karger AG, Basel.

    End-stage renal disease (ESRD) is an irreversible and life-threatening condition. In Jordan, the number of ESRD patients treated with hemodialysis is on the rise. Identifying stressors and coping strategies used by patients with ESRD may help nurses and health care providers to gain a clearer understanding of the condition of these patients and thus institute effective care planning. The purpose of this study was to identify stressors perceived by Jordanian patients on hemodialysis, and the coping strategies used by them. A convenience sample of 131 Jordanian men and women was recruited from outpatients' dialysis units in four hospitals. Stressors perceived by participants on hemodialysis and the coping strategies were measured using Hemodialysis Stressor Scale, and Ways of Coping Scale-Revised. Findings showed that patients on hemodialysis psychosocial stressors scores mean was higher than the physiological stressors mean. Positive reappraisal coping strategy had the highest mean among the coping strategies and the lowest mean was accepting responsibility. Attention should be focused towards the psychosocial stressors of patients on hemodialysis and also helping patients utilize the coping strategies that help to alleviate the stressors. The most used coping strategy was positive reappraisal strategy which includes faith and prayer.

    Summary Background and objectives Achieving and maintaining optimal fluid status remains a major challenge in hemodialysis therapy. The aim of this interventional study was to assess the feasibility and clinical consequences of active fluid management guided by bioimpedance spectroscopy in chronic hemodialysis patients. Design, setting, participants, & measurements Fluid status was optimized prospectively in 55 chronic hemodialysis patients over 3 months (November 2011 to February 2012). Predialysis fluid overload was measured weekly using the Fresenius Body Composition Monitor. Time-averaged fluid overload was calculated as the average between pre- and postdialysis fluid overload. The study aimed to bring the time-averaged fluid overload of all patients into a target range of 0.5±0.75 L within the first month and maintain optimal fluid status until study end. Postweight was adjusted weekly according to a predefined protocol. Results Time-averaged fluid overload in the complete study cohort was 0.9±1.6 L at baseline and 0.6±1.1 L at study end. Time-averaged fluid overload decreased by −1.20±1.32 L (P<0.01) in the fluid-overloaded group (n=17), remained unchanged in the normovolemic group (n=26, P=0.59), and increased by 0.59±0.76 L (P=0.02) in the dehydrated group (n=12). Every 1 L change in fluid overload was accompanied by a 9.9 mmHg/L change in predialysis systolic BP (r=0.55, P<0.001). At study end, 76% of all patients were either on time-averaged fluid overload target or at least closer to target than at study start. The number of intradialytic symptoms did not change significantly in any of the subgroups. Conclusions Active fluid management guided by bioimpedance spectroscopy was associated with an improvement in overall fluid status and BP. PMID:23949235

    Patients with chronic renal failure (CRF) were on maintenance invasive hemodialysis (HD) procedure. This procedure by itself affects immunity of the patients and became more susceptible to viral infections. to investigate the occurrence of HBV, HCV and HIV infections in patients with hemodialysis. A retrospective study of 430 end-stage renal failure patients, referred to hemodialysis department at XXXX Teaching Hospital, Baghdad-Iraq from January-2015 to January-2017. Patients were investigated for HBs-Ag using enzyme-labeled antigen test (Foresight-EIA-USA), HCV- Abs (IgG) specific immunoglobulin using an HCV enzyme-labeled antigen test (Foresight-EIA-USA)and anti - HIV Abs (IgG) using enzyme-labeled antigen test (Foresight-EIA-USA). The frequency of HBV infection in the first year was not significant between males (1.11%) and females (0.00%) (P = 0.295). About HCV also there are no significant differences between males (12.63%) and females (9.31%) (P = 0.347). After one year of follow up the frequencies of HBV and HCV were not significant between two sexes. Additionally, no any one of the patients had HIV infection. This study brings a light on that HBV and HCV were having the same frequencies in both genders and lower occurrence with time. Furthermore, HIV was not detected in those patients.

    This study was designed to investigate the effects of aromatherapy on pruritus in patients with chronic renal failure undergoing hemodialysis. The participants were 29 adult patients living in Seoul, Korea. Thirteen patients were assigned to the experimental group and received the aromatherapy massage on the arm 3 times a week for 4 weeks. Pruritus score, skin pH, stratum corneum hydration, and pruritus-related biochemical markers were measured before and after the treatment. The results showed that pruritus score was significantly decreased after aromatherapy. Skin pH showed no significant changes in either group while stratum corneum hydration increased significantly in the experimental group after aromatherapy. The results support the use aromatherapy as a useful and effective method of managing pruritus in patients undergoing hemodialysis.

    Cerebral venous oxygen saturation (SvO 2 ) is an important indicator of brain function. There was debate about lower cerebral oxygen metabolism in hemodialysis patients and there were no reports about the changes of deep regional cerebral SvO 2 in hemodialysis patients. In this study, we aim to explore the deep regional cerebral SvO 2 from straight sinus using quantitative susceptibility mapping (QSM) and the correlation with clinical risk factors and neuropsychiatric testing . 52 hemodialysis patients and 54 age-and gender-matched healthy controls were enrolled. QSM reconstructed from original phase data of 3.0 T susceptibility-weighted imaging was used to measure the susceptibility of straight sinus. The susceptibility was used to calculate the deep regional cerebral SvO 2 and compare with healthy individuals. Correlation analysis was performed to investigate the correlation between deep regional cerebral SvO 2 , clinical risk factors and neuropsychiatric testing. The deep regional cerebral SvO 2 of hemodialysis patients (72.5 ± 3.7%) was significantly lower than healthy controls (76.0 ± 2.1%) (P < 0.001). There was no significant difference in the measured volume of interests of straight sinus between hemodialysis patients (250.92 ± 46.65) and healthy controls (249.68 ± 49.68) (P = 0.859). There were no significant correlations between the measured susceptibility and volume of interests in hemodialysis patients (P = 0.204) and healthy controls (P = 0.562), respectively. Hematocrit (r = 0.480, P < 0.001, FDR corrected), hemoglobin (r = 0.440, P < 0.001, FDR corrected), red blood cell (r = 0.446, P = 0.003, FDR corrected), dialysis duration (r = 0.505, P = 0.002, FDR corrected) and parathyroid hormone (r = -0.451, P = 0.007, FDR corrected) were risk factors for decreased deep regional cerebral SvO 2 in patients.

    The high risk of morbidity and mortality for patients on hemodialysis who are undergoing cardiac surgery is increased for those with active infective endocarditis (AIE). This retrospective observational single-center study evaluated the impact of chronic hemodialysis on the outcome of aortic valve replacement in patients with aortic AIE. Data were retrospectively collected for consecutive patients undergoing aortic valve surgery for AIE diagnosed according to modified Duke criteria between October 1994 and January 2011. Characteristics and outcomes of patients receiving preoperative chronic hemodialysis were analyzed. Aortic valve AIE was present in 992 patients. Forty-five (4.5%) of the aortic valve AIE patients were receiving long-term hemodialysis preoperatively, 19 of whom (42.2%) had diabetes mellitus. Mean logistic EuroSCORE was 64.2% ± 32.2%. Twenty-four preoperative septic emboli were found in 15 patients. Results of microbiologic cultures were positive in 36 patients, with the major causative organisms identified as Staphylococcus aureus (n = 17) and Enterococcus faecalis (n = 10). Isolated aortic valve replacement was performed in 19 patients (42.2%), and 26 patients (57.8%) underwent concomitant procedures. The mean follow-up was 5.3 ± 5.2 years (range, 0.1 to 17.1 years). Postoperative complications occurred in 30 patients (66.7%). Nineteen patients (42.2%) died within 30 days of surgery, which in 8 patients was attributable to a cardiac cause. In patients receiving chronic hemodialysis who undergo aortic valve replacement for acute AIE, postoperative mortality is high, especially in patients undergoing aortic root replacement or culture-negative AIE.

    Patients with end-stage renal disease (ESRD) have a high symptom burden and this negatively impacts health-related quality of life. Little is known about the symptom burden of Latinos with ESRD and variable access to hemodialysis. To estimate the symptom burden of Latinos with ESRD and access to standard or emergency-only hemodialysis. Observational descriptive study of Latino adults with ESRD receiving standard or emergency-only hemodialysis. Patients completed the Edmonton Symptom Assessment System Revised: Renal (ESAS-r:Renal). We used descriptive statistics and propensity score adjustment to conduct the analysis. ESAS-r:Renal. Participants (N = 67) had a mean age of 58 years (standard deviation [SD] ±13) and a mean Charlson Comorbidity Index of 6.6 ± 2.5, and had been on hemodialysis a mean of 42 months (SD ±43). On average, Latinos with ESRD experienced 7 (SD ±3) symptoms with a mean of 5 ± 3 symptoms reported as moderate or severe. After adjusting for propensity score, emergency-only hemodialysis patients reported experiencing more nausea compared to standard hemodialysis patients (odds ratio 8.95, 95% confidence interval: 1.17-68.31, p = 0.03). Latinos with ESRD have a high symptom burden and compared to patients with standard hemodialysis, patients who rely on emergency-only hemodialysis report more nausea. A national treatment strategy that provides standard hemodialysis for undocumented immigrants with ESRD is an important next step.

    Dialysis disequilibrium syndrome (DDS) is a serious neurological complication of hemodialysis, and patients with acute brain injury are at increased risk. We report a case of DDS leading to intracranial hypertension in a patient with anoxic brain injury and discuss the subsequent dialysis strategy. A 13-year-old girl was admitted after prolonged resuscitation from cardiac arrest. Computed tomography (CT) revealed an inferior vena cava aneurysm and multiple pulmonary emboli as the likely cause. An intracranial pressure (ICP) monitor was inserted, and, on day 3, continuous renal replacement therapy (CRRT) was initiated due to acute kidney injury, during which the patient developed severe intracranial hypertension. CT of the brain showed diffuse cerebral edema. CRRT was discontinued, sedation was increased, and hypertonic saline was administered, upon which ICP normalized. Due to persistent hyperkalemia and overhydration, ultrafiltration and intermittent hemodialysis were performed separately on day 4 with a small dialyzer, low blood and dialysate flow, and high dialysate sodium content. During subsequent treatments, isolated ultrafiltration was well tolerated, whereas hemodialysis was associated with increased ICP necessitating frequent pauses or early cessation of dialysis. In patients at risk of DDS, hemodialysis should be performed with utmost care and continuous monitoring of ICP should be considered.

    Background Fast food consumption has increased dramatically in the general population over the last 25 years. However, little is known about the prevalence and nutritional implications of fast food consumption among hemodialysis patients. Methods Using a cross-sectional study design, we obtained data on fast food consumption and nutrient intake (from four separate 24-hour dietary recalls) and nutritional parameters (from chart abstraction) for 194 randomly selected patients from 44 hemodialysis facilities in northeast Ohio. Results Eighty-one subjects (42%) reported consuming at least one fast food meal or snack in four days. Subjects who consumed more fast food had higher kilocalorie, carbohydrate, total fat, saturated fat, and sodium intakes. For example, kilocalorie per kilogram intake per day increased from 18.9 to 26.1 with higher frequencies of fast food consumption (p=.003). Subjects who consumed more fast food also had higher serum phosphorus levels and interdialytic weight gains. Conclusion Fast food is commonly consumed by hemodialysis patients and is associated with a higher intake of kilocalories, carbohydrates, fats, and sodium and adverse changes in phosphorus and fluid balance. Further work is needed to understand the long-term benefits and risks of fast food consumption among hemodialysis patients. PMID:17586425

    Occult hepatitis B infection is the case with undetectable HBsAg, but positive for HBV DNA in liver tissue and/or serum. Occult hepatitis B infection among hemodialysis patients in Palestine has been understudied. In this study, 148 hemodialysis patients from 2 northern districts in Palestine, Jenin (89) and Tulkarem (59), were investigated for occult hepatitis B, HBV, HCV infections with related risk factors. ELISA and PCR were used for the detection of anti-HBc and viral DNA, respectively. The overall prevalence of occult hepatitis B infection among the study group was 12.5% (16/128). Occult hepatitis B infection is more prevalent among males with most cases (15/16) from Jenin District. About one-third (42/132) of the hemodialysis patients were anti-HBc positive. Approximately 27% of the hemodialysis patients were infected with HCV. Around 20% (28/140) were positive for HBV DNA, but only 8.2% (12/146) of the hemodialysis patients were positive for HBsAg. The comparison between hemodialysis patients with occult hepatitis B infection and those without occult hepatitis B infection for selected risk factors and parameters as liver Enzyme, age, sex, HCV infection, blood transfusion, kidney transplant, anti-HBc, and vaccination showed no statistical significance between both categories. Duration of hemodialysis significantly affected the rate of HCV infection. HCV is significantly higher in hemodialysis patients with both Diabetes mellitus and hypertension. The prevalence of occult hepatitis B infection among hemodialysis patients is high; requiring stringent control policies. HBsAg assay is insufficient test for accurate diagnosis of HBV infection among hemodialysis patients. © 2014 Wiley Periodicals, Inc.

    Background Health-related quality of life (HRQOL) is often prioritized over long-term survival in elderly patients. Although a longer dialysis session length (DSL) has been shown to reduce mortality, its effects on improving the HRQOL are unknown. Methods Using data from the Japan Dialysis Outcomes and Practice Patterns Study (J-DOPPS), patients aged ≥ 65 years on maintenance hemodialysis were enrolled. DSL was categorized as short (<210 minutes), medium (210–240 minutes), or long (>240 minutes). The primary outcomes were changes in mental health (ΔMH) and physical functioning (ΔPF) scores assessed using the Japanese version of SF-12, in one year. The differences in the ΔMH and ΔPF among the three groups were assessed via regression (beta) coefficients derived using a linear regression model. Results Of 1,187 patients at baseline, 319 (26.9%) had a short length, 686 (57.8%) a medium length, and 182 (15.3%) a long length. We assessed the ΔMH data from 793 patients and the ΔPF data from 738. No significant differences in the ΔMH were noted for the short or long groups compared with the medium group (score difference: 0.26, 95% confidence interval [CI]: -4.17 to 4.69 for short; score difference: -1.15, 95% CI: -6.17 to 3.86 for long). Similarly, no significant differences were noted for these groups versus the medium group in ΔPF either (score difference: -1.43, 95% CI: -6.73 to 3.87 for short; score difference: -1.71, 95% CI: -7.63 to 4.22 for long). Conclusions A shorter DSL might have no adverse effects on MH or PF for elderly patients. PMID:28877202

Beta2-Microglobulin (β2M) is an independent predictor of outcome for hemodialysis patients and a representative substance of middle molecules. In 40 patients in high-flux membrane hemodialysis, we found negative correlation of β2M with high density lipoprotein (r=-0.73, p<0.001) and albumin (r= -0.53, p<0.001) and positive correlation with triglycerides (r=0.69, p<0.001), parathyroid hormone (r=0.58, p < 0.05) and phosphorus (r= 0.53, p<0.001). There was no correlation of β2M with C- reactive protein (CRP) and interleukin-6 (IL-6). During the follow-up period of three years, 6 out of 40 patients have died from cardiovascular events. In high-flux membrane hemodialysis patients, we observed a significant relationship of β2M with dyslipidemia and mineral bone disorders, but there was no correlation with inflammation.

    A patient on hemodialysis for end-stage renal disease secondary to diabetic nephropathy was admitted in a coma with Kussmaul breathing and hypertension (232/124 mmHg). She had extreme hyperglycemia (1884 mg/dL), acidosis (total CO(2) 4 mmol/L), hyperkalemia (7.2 mmol/L) with electrocardiographic abnormalities, and hypertonicity (330.7 mOsm/kg). Initial treatment with insulin drip resulted in a decrease in serum potassium to 5.3 mmol/L, but no significant change in mental status or other laboratory parameters. Hemodialysis of 1.75 hours resulted in rapid decline in serum glucose and tonicity and rapid improvement of the acidosis, but no change in mental status, which began to improve slowly after the hemodialysis was stopped, but with ongoing treatment with continuous insulin infusion. The rate of decline in tonicity during hemodialysis (14.5 mOsm/kg/h) was high, raising concerns about neurological complications. In this case, extreme hyperglycemia with ketoacidosis, hyperkalemia, and coma developing in a hemodialysis patient responded to insulin infusion. Monitoring of the clinical status and the pertinent laboratory values is required to assess the need for other therapeutic measures including volume and potassium replacement and emergency dialysis. The indications for and risks of emergency dialysis in this setting are not clearly defined.

    Cardiovascular disease is the leading cause of mortality among patients on dialysis. When considering all causes of death, about 30% are classified as cardiac arrest, death of unknown cause or cardiac arrhythmia. The increasing time of ventricular depolarization and repolarization, measured non-invasively by measuring the QT interval on the electrocardiogram at rest, has emerged as a predictor of complex ventricular arrhythmias, a major cause of sudden cardiac death. To determine the electrocardiographic alterations present in hemodialysis (HD) patients, measuring the QT interval and its relationship with clinical and laboratory variables. Patients above 18 years on dialysis were approached to participate in the study and, after consent, were submitted to the examination of 12-lead electrocardiogram. Clinical data were reviewed to assess the presence of comorbidities, as well as anthropometric and blood pressure measures. Blood samples were collected to determinate hemoglobin and serum levels of calcium, phosphorus and potassium. One hundred and seventy nine patients were included in the study. The majority of the patients were male (64.8%) and white (54.7%); the average age was 58.5 ± 14.7 years old. About 50% of all patients had, at least, one electrical conduction disturb. About 50% of all patients had QTc prolongation and experienced a significant increase in the frequency of Left Ventricular Hypertrophy (LVH), changes of the cardiac rhythm and bundle branch blocks, and a lower body mass index (BMI), when compared with normal QTc interval patients. Patients with chronic kidney disease (CKD) on hemodialysis had high frequency of abnormal electrocardiographic findings, including a high prevalence of patients with prolonged QTc interval. This study also found a significant association between prolonged QTc interval and the presence of Diabetes and lower values of BMI.

    The aim of the present study was to compare the experience elderly and younger patients in terms of emotional status, disease perception, methods of coping with the end-stage renal disease (ESRD) stress, and health-related quality of life in 2 different settings of renal replacement therapy: hemodialysis (HD) and continuous ambulatory peritoneal dialysis programs (CAPD). Specifically, we hypothesized that younger people will more frequently use goal-oriented strategies to cope with illness-related stress and elderly patients will use more strategies related to the control of emotion. A total of 69 HD patients, 40 CAPD patients, and 89 healthy volunteers were analyzed. The Situation and Trait Anxiety Inventory, the Profile of Mood States, the Cognitive Stress Appraisal Questionnaire, and the Nottingham Health Profile were used to assess anxiety, long-term emotional status, coping mechanisms, and health-related quality of life. Data were collected on several biochemical and demographic variables. Our study revealed that younger and elderly people on dialysis faced quite different problems. Younger people in both RRT groups had statistically higher assessment of ESRD as loss or challenge and they more frequently used distractive and emotional preoccupation coping strategies. Depression, confusion, and bewilderment dominate the emotional status of both patient populations, especially in the younger cohort. Both HD(young) and CAPD(young) patients complained more about lack of energy, mobility limitations, and sleep disturbances as compared to their elderly HD and CAPD counterparts. There are different needs and problems in younger and elderly patients on renal replacement therapy. Younger people required more ESRD-oriented support to relieve their health-related complaints to the level observed in their peers and needed extensive psychological assistance in order to cope with negative emotions related to their disease.

    A patient-centered quality improvement program implemented in one Virginia hemodialysis facility sought to determine if peer-to-peer (P2P) programs can assist patients on in-center hemodialysis with self-management and improve outcomes. Using a single-arm, repeatedmeasurement, quasi-experimental design, 46 patients participated in a four-month P2P intervention. Outcomes include knowledge, self-management behaviors, and psychosocial health indicators: self-efficacy, perceived social support, hemodialysis social support, and healthrelated quality of life (HRQoL). Physiological health indicators included missed and shortened treatments, arteriovenous fistula placement, interdialytic weight gain, serum phosphorus, and hospitalizations. Mentees demonstrated increased knowledge, self-efficacy, perceived social support, hemodialysis social support, and HRQoL. Missed treatments decreased. Mentors experienced increases in knowledge, self-management, and social support. A P2P mentoring program for in-center hemodialysis can benefit both mentees and mentors.

    Lean body mass (LBM) is an important nutritional measure representing muscle mass and somatic protein in hemodialysis patients, for whom we developed and tested equations to estimate LBM. A study of diagnostic test accuracy. The development cohort included 118 hemodialysis patients with LBM measured using dual-energy x-ray absorptiometry (DEXA) and near-infrared (NIR) interactance. The validation cohort included 612 additional hemodialysis patients with LBM measured using a portable NIR interactance technique during hemodialysis. 3-month averaged serum concentrations of creatinine, albumin, and prealbumin; normalized protein nitrogen appearance; midarm muscle circumference (MAMC); handgrip strength; and subjective global assessment of nutrition. LBM measured using DEXA in the development cohort and NIR interactance in validation cohorts. In the development cohort, DEXA and NIR interactance correlated strongly (r = 0.94, P < 0.001). DEXA-measured LBM correlated with serum creatinine level, MAMC, and handgrip strength, but not with other nutritional markers. Three regression equations to estimate DEXA-measured LBM were developed based on each of these 3 surrogates and sex, height, weight, and age (and urea reduction ratio for the serum creatinine regression). In the validation cohort, the validity of the equations was tested against the NIR interactance-measured LBM. The equation estimates correlated well with NIR interactance-measured LBM (R² ≥ 0.88), although in higher LBM ranges, they tended to underestimate it. Median (95% confidence interval) differences and interquartile range for differences between equation estimates and NIR interactance-measured LBM were 3.4 (-3.2 to 12.0) and 3.0 (1.1-5.1) kg for serum creatinine and 4.0 (-2.6 to 13.6) and 3.7 (1.3-6.0) kg for MAMC, respectively. DEXA measurements were obtained on a nondialysis day, whereas NIR interactance was performed during hemodialysis treatment, with the likelihood of confounding by volume status

    Fatigue is one of the most highly prioritized outcomes for patients and clinicians, but remains infrequently and inconsistently reported across trials in hemodialysis. We convened an international Standardized Outcomes in Nephrology-Hemodialysis (SONG-HD) consensus workshop with stakeholders to discuss the development and implementation of a core outcome measure for fatigue. 15 patients/caregivers and 42 health professionals (clinicians, researchers, policy makers, and industry representatives) from 9 countries participated in breakout discussions. Transcripts were analyzed thematically. 4 themes for a core outcome measure emerged. Drawing attention to a distinct and all-encompassing symptom was explicitly recognizing fatigue as a multifaceted symptom unique to hemodialysis. Emphasizing the pervasive impact of fatigue on life participation justified the focus on how fatigue severely impaired the patient's ability to do usual activities. Ensuring relevance and accuracy in measuring fatigue would facilitate shared decision making about treatment. Minimizing burden of administration meant avoiding the cognitive burden, additional time, and resources required to use the measure. A core outcome measure that is simple, is short, and includes a focus on the severity of the impact of fatigue on life participation may facilitate consistent and meaningful measurement of fatigue in all trials to inform decision making and care of patients receiving hemodialysis.

    We used high-resolution quantitative computed tomography to study the microarchitecture of bone in patients with chronic kidney disease on dialysis. We compared bone characteristics in 56 maintenance hemodialysis (21 women, 14 post-menopausal) and 23 peritoneal dialysis patients (9 women, 6 post-menopausal) to 79 healthy men and women from two cohorts matched for age, body mass index, gender, and menopausal status. All underwent dual-energy X-ray absorptiometry of the spine and hip to measure areal bone mineral density, and high-resolution peripheral quantitative computed tomography of the radius and tibia to measure volumetric bone mineral density and microarchitecture. When compared to their matched healthy controls, patients receiving hemodialysis and peritoneal dialysis had a significantly lower areal bone mineral density in the hip. Hemodialysis patients had significantly lower total, cortical, and trabecular volumetric bone mineral density at both sites. Hemodialysis patients had significantly lower trabecular volumetric bone mineral density and microarchitecture at the tibia than the peritoneal dialysis patients. Overall, peritoneal dialysis patients were less affected, their cortical thickness at the distal tibia being the only significant difference versus controls. Thus, we found more severe trabecular damage at the weight-bearing tibia in hemodialysis compared to peritoneal dialysis patients, but this latter finding needs confirmation in larger cohorts.

    The relationship between residual urine output and postoperative survival in maintenance hemodialysis patients is unknown. To explore the relationship between amount of urine before surgery and postoperative mortality and differences between postoperative nonanuria and anuria in maintenance hemodialysis patients. A total of 109 maintenance hemodialysis patients underwent major operations. Anuria was defined as urine output <30 mL in the 8 hours before the first session of postoperative dialysis. Propensity scores for postoperative anuria were developed. Postoperative residual urine output was 159.2 mL/8 h (SD, 115.1) in 33 patients; 76 patients were anuric. Preoperative residual urine output and adequate perioperative blood transfusion were positively related to postoperative urine output. Propensity-adjusted 30-day mortality was associated with postoperative anuria (odds ratio [OR], 4.56; 95% confidence interval [CI], 1.16-17.96; P = .03), prior stroke (OR, 4.46; 95% CI, 1.43-13.89; P = .01) and higher disease severity (OR, 1.10; 95% CI, 1.00-1.21; P = .049) at the first postoperative dialysis. OR of 30-day mortality was 5.38 for nonanuria to anuria vs nonanuria to nonanuria (P = .03) and 5.13 for preoperative anuria vs nonanuria to nonanuria (P = .01). By Kaplan-Meier analysis, 30-day mortality differed significantly among patients for nonanuria to nonanuria, anuria, and nonanuria to anuria (log rank, P = .045). Patients with preoperative nonanuria and postoperative anuria had higher mortality than did patients with no anuria before and after surgery and patients with anuria before surgery. Postoperative residual urine output is an important surrogate marker for disease severity.

    The present study aims to evaluate iron related parameters in chronic renal failure (CRF) patients on hemodialysis (HD). The study was carried out in Kidney Dialysis Center of Hawler Teaching Hospital in Erbil governorate. This study comprised (76) patients with chronic renal failure on hemodialysis and 41 healthy subjects as a control group of same ages. All hemodialysis patients were taking erythropoietin. The blood samples were taken from the patients before and after the process of hemodialysis for liver parameters and oxidative stress estimations. The results of this study showed lower levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), albumin, total bilirubin, total protein and total antioxidant capacity (TAC), while higher levels of alkaline phosphatase (ALP), direct bilirubin and malondialdeyhde (MDA) before analysis was seen. Hemodialysis causes increasing in AST, ALT, albumin, total bilirubin, total protein and decreasing in ALP, direct bilirubin MDA and TAC.

    Iliopsoas abscess is a rare complication in hemodialysis patients that is mainly due to adjacent catheterization, local acupuncture, discitis, and bacteremia. Herein, we report a 47-year-old woman undergoing regular hemodialysis via a catheter in the internal jugular vein who presented with low back pain and dyspnea. A heart murmur suggested the presence of catheter-related endocarditis, and this was confirmed by an echocardiogram and a blood culture of methicillin-resistant Staphylococcus aureus. A computed tomography indicated a pulmonary embolism and an incidental finding of iliopsoas abscess. Following surgical intervention and intravenous daptomycin, the patient experienced full recovery and a return to usual activities. This case indicates that an iliopsoas abscess can be related to a jugular vein catheter, which is apparently facilitated by infective endocarditis. The possibility of iliopsoas abscess should be considered when a hemodialysis patient presents with severe low back pain, even when there is no history of adjacent mechanical intervention. © 2014 International Society for Hemodialysis.

    Fluid limitations are difficult for hemodialysis patients to follow, and factors related to fluid adherence are not well known. The primary purpose of this study, which was guided by the health belief model and the transtheoretical model for behavior change, was to determine whether differences exist in perceived benefits, barriers, susceptibility, seriousness, or self-efficacy among individuals in different stages of fluid adherence. In a cross-sectional descriptive design, 148 persons (mean age=53.9 years; 52% male) were interviewed using a structured format. Hemodialysis patients in the action/maintenance stage perceived significantly more benefits to fluid adherence than persons in the precontemplation stage. Persons who were in the action/maintenance stage perceived they were significantly more susceptible to pulmonary edema than persons in the contemplation stage. Stage-appropriate interventions may be needed to target specific beliefs about fluid adherence. Copyright 2001 John Wiley & Sons, Inc.

    Pain during areteriovenous fistula (AVF) cannulation remains a common problem in hemodialysis (HD) patients. This study was undertaken to assess the effect of cryotherapy on pain due to arteriovenous fistula puncture in hemodialysis patients. A convenience sample of 60 patients (30 each in experimental and control groups) who were undergoing hemodialysis by using AVF, was assessed in a randomized control trial. Hemodialysis patients who met the inclusion criteria, were randomly assigned to experimental and control groups using a randomization table. Objective and subjective pain scoring was done on two consecutive days of HD treatment (with cryotherapy for the experimental and without cryotherapy for the control group). The tools used were a questionnaire examining demographic and clinical characteristics, an observation checklist for assessing objective pain behavior, and a numerical rating scale for subjective pain assessment. Descriptive statistics were used as deemed appropriate. Chi square, two-sample and paired t-tests, the Mann Whitney test, Wilcoxon's signed rank test, the Kruskal Wallis test, and Spearman's and Pearson's correlations were used for inferential statistics. We found that the objective and subjective pain scores were found to be significantly (P = 0.001) reduced within the experimental group with the application of cryotherapy. This study highlights the need for adopting alternative therapies such as cryotherapy for effective pain management in hospital settings.

    HFE gene mutations are responsible from iron overload in general population. Studies in hemodialysis patients investigated the effect of presence of HFE gene mutations on serum ferritin and transferrin saturation (TSAT) with conflicting results. However effect of HFE mutations on iron overload in hemodialysis patients was not previously extensively studied. 36 hemodialysis patients (age 51.3 ± 15.6, (18/18) male/female) and 44 healthy control subjects included in this cross sectional study. Hemoglobin, ferritin, TSAT in the preceding 2 years were recorded. Iron and erythropoietin (EPO) administered during this period were calculated. Iron accumulation in heart and liver was detected by MRI. Relationship between HFE gene mutation, hemoglobin, iron parameters and EPO doses, and tissue iron accumulation were determined. Iron overload was detected in nine (25%) patients. Hemoglobin, iron parameters, weekly EPO doses, and monthly iron doses of patients with and without iron overload were similar. There was no difference between control group and hemodialysis patients with respect to the prevalence of HFE gene mutations. Iron overload was detected in five of eight patients who had HFE gene mutations, but iron overload was present in 4 of 28 patients who had no mutations (P = 0.01). Hemoglobin, iron parameters, erythropoietin, and iron doses were similar in patients with and without gene mutations. HFE gene mutations remained the main determinant of iron overload after multivariate logistic regression analysis (P = 0.02; OR, 11.6). Serum iron parameters were not adequate to detect iron overload and HFE gene mutation was found to be an important risk factor for iron accumulation. © 2017 International Society for Hemodialysis.

    Unfractionated (UF) heparin is the most common anticoagulant used during hemodialysis. Failure of the kidneys to excrete potassium as well as heparin-induced reduction of aldosterone synthesis put hemodialysis patients at risk of hyperkalemia. It has not yet been clearly known whether hyperkalemia is also induced by low-molecular-weight (LMW) heparins. This study aimed to evaluate the effect of switching UF heparin to LMW heparin enoxaparin, as an anticoagulant during hemodialysis, on serum potassium level in patients on hemodialysis. In two hemodialysis units, 58 patients were randomly assigned into two groups, to receive two different anticoagulation protocols for 3 weeks; one group continued to receive their routine dose of UF heparin, 5000 units, and the other received enoxaparin, 0.5 mg/kg, at the beginning of each hemodialysis session. While there was no significant difference between baseline blood measurements of the two groups in terms of kidney function tests and electrolytes, following 3 weeks of the study, the mean serum potassium level decreased from 4.9 ± 0.8 mEq/L to 4.5 ± 0.5 mEq/L in the LMW heparin group (P = .001); however, there was no change in the mean serum potassium level in those who continued to receive their usual dose of UF heparin. In a subgroup analysis, diabetic patients in the enoxaparin group did not experience significant reduction in serum potassium levels. Our study revealed the role of LMW heparins as a potential alternative to UF heparins in the hemodialysis patients with hyperkalemia.

    Background: Catheter-related infections (CRIs) are a significant source of morbidity and mortality in hemodialysis patients. The identification of novel, modifiable risk factors for CRIs may lead to improved outcomes in this population. Peripherally inserted central catheters (PICCs) have been hypothesized to compromise vascular access due to vascular damage and venous thrombosis, whereas venous thrombosis has been linked to the development of CRIs. Here we examine the association between PICC placement and CRIs. Methods: A retrospective review was performed of all chronic hemodialysis catheter placements and exchanges performed at a large university hospital from September 2003 to September 2008. History ofmore » PICC line use was determined by examining hospital radiologic records from December 1993 to September 2008. Catheter-related complications were assessed and correlated with PICC line history. Results: One hundred eighty-five patients with 713 chronic tunneled hemodialysis catheter placements were identified. Thirty-eight of those patients (20.5%) had a history of PICC placement; these patients were more likely to have CRIs (odds ratio = 2.46, 95% confidence interval = 1.71-3.53, p < .001) compared with patients without a history of PICC placement. There was no difference between the two groups in age or number of catheters placed. Conclusion: Previous PICC placement may be associated with catheter-related infections in hemodialysis patients.« less

    Calcium alpha-ketoglutarate administration to 24 malnourished hemodialysis patients for 1 year leads to a significant increase in plasma concentrations of L-arginine from 53.6 +/- 18.3 (compared to a healthy control group: 87.5 +/- 27.3) to 71.1 +/- 15.9 mumol/l (p < 0.05). Furthermore, concentrations in plasma of proline and histidine, precursors of glutamate biosynthesis, are increased; inorganic phosphate and urea are significantly decreased in hemodialysis patients after 1 year of calcium alpha-ketoglutarate administration.

    Recent research highlights the potential burdens of hemodialysis for older patients with significant comorbidities, for whom there is clinical equipoise regarding the net benefits. With the advent of accountable care and bundled payment, previous incentives to offer hemodialysis to as many patients as possible are being replaced with a disincentive to dialyze high-risk patients. While this may offset the harm of overtreatment for some elderly patients, some voice concerns that the pendulum will swing too far back, with a return to ageist rationing of hemodialysis. Nephrologists should ensure that the patient's rights to be informed about the potential benefits and burdens of hemodialysis are respected, particularly because age, functional status, nutritional status, and comorbidities affect the net balance between benefits and burdens. Nephrologists are also called on to help patients make a decision, for which the patient's goals of care guide determination of potential benefit from hemodialysis. This article addresses concerns about present overtreatment and future risk of undertreatment of older adults with ESRD. It also discusses ways in which providers can ethically approach the question of initiation of hemodialysis in the elderly patient by including patient-specific estimates of prognosis, shared decision-making, and the use of specialist palliative care clinicians or ethics consultants for complex cases.

    The Japan Society for Dialysis Therapy established "Guidelines for the Treatment of Hepatitis C Virus Infection in Dialysis Patients." We evaluated the status of HCV infection and the treatment of hemodialysis patients in Gunma prefecture. Questionnaires concerning the infection rate, recognition of the guidelines, and treatment status were sent to all 64 hospitals/clinics that had hemodialysis systems in Gunma prefecture. The hepatitis C virus-infected hemodialysis patients who received pegylated interferon (peg-IFN) were analyzed at Gunma University Hospital. The positive rate for hepatitis C virus antibody was 256/2582 hemodialysis patients (9.9%). The positive rate varied between institutions (range 0-40.0%; median 9.0%). All institutes recognized the establishment of the guidelines. Conventional or peg-IFN treatment was being given at 37.5% of the institutions. The other 62.5% institutions answered that they intended to provide the treatment in the future if collaboration with a hepatologist could be arranged. The most common answers regarding the indication for IFN treatment were as follows: few complications, under 60 years of age, more than 10 years of survival expected on hemodialysis. Eighteen patients received peg-IFN treatment. The sustained virological response rate of all patients was 33.3%, 0% in 1b/high viral titer, 50% in genotype 2, and 100% in genotype 2/low viral titer. The sustained virological response rate was worse in the patients with 1b/high viral load and diabetic nephropathy (P < 0.05). Recognition of the publication of the guidelines was high. However, the number of patients treated with peg-IFN was still low. Further enlightenment and cooperation between hemodialysis teams and hepatologists are therefore needed. © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    Interatrial conduction delays manifest as a prolonged P-wave duration on surface ECG and the term interatrial block (IAB) has been coined. They are usually fixed, but cases of intermittent IAB have been described, suggesting functional conduction block at the Bachmann bundle region. We report 2 cases of patients on chronic hemodialysis therapy presenting with intermittent IAB. PMID:25755895

    Pentosidine is an advanced glycation end product (AGE). The present study was undertaken to investigate the association of serum pentosidine with carotid distensibility as a measure of arterial stiffness in hemodialysis patients. One hundred and three patients on maintenance hemodialysis were recruited. The distensibility coefficient of the common carotid artery was evaluated by an ultrasonic phase-locked echo-tracking system. Serum pentosidine was measured by competitive enzyme-linked immunosorbent assay. Serum albumin, lipid profile, calcium, phosphorus, intact parathyroid hormone (iPTH), high-sensitivity C-reactive protein (hs-CRP), and oxidized low-density lipoprotein (ox-LDL) levels were also measured. Correlation was determined by linear and multiple stepwise regression analysis. Serum pentosidine level studied in hemodialysis patients was 0.54 +/- 0.13 microg/mL. No significant difference in serum pentosidine level was noted between patients with and without diabetes (0.59 +/- 0.10 microg/mL vs. 0.53 +/- 0.13 microg/mL, P = 0.062) as well as between patients with and without prior cardiovascular disease (CVD) history (0.56 +/- 0.14 microg/mL vs. 0.53 +/- 0.12 microg/mL, P = 0.206). In multivariate regression analysis, only age (beta = 0.363, P < 0.001) and ox-LDL (beta = 0.262, P = 0.004) were identified as independent determinants for serum pentosidine. Serum pentosidine was significantly correlated with carotid distensibility (r = -0.387, P < 0.001), as well as age, ox-LDL, and hs-CRP. After adjustment for age, blood pressure, history of diabetes, prior CVD history, lipid profile, calcium, phosphorus, iPTH, hs-CRP, and ox-LDL, serum pentosidine was still negatively correlated with distensibility (beta = -0.175, P = 0.044). Serum pentosidine was independently associated with carotid distensibility in hemodialysis patients. This finding suggested that the accumulation of AGE might be an important pathway in the development of arterial stiffness in end

    Hemophilia A is a hereditary X-linked recessive disease caused by mutations in the gene encoding factor VIII (FVIII), occurring in 1 out of 10,000 persons. Life expectancy and quality of life have dramatically improved recently in patients with hemophilia. Chronic kidney disease and need for renal replacement therapy in these patients are rare. The development of inhibitors to FVIII is the most serious complication of hemophilia and makes treatment of bleeds very challenging. We describe here a 28-year-old male patient with severe hemophilia A with presence of factor VIII inhibitor, who had end stage renal disease. Central venous access device was inserted along with infusion of factor eight inhibitor bypass activity before and after the procedure. He is currently on thrice weekly hemodialysis and doing well for 6 months without bleeding episodes. To our knowledge, hemophilia A with factor VIII inhibitor managed with hemodialysis has not been reported so far. © 2016 International Society for Hemodialysis.

    Fungal endocarditis (FE) is commonly regarded as a rare but fatal disease. The incidence of infective endocarditis (IE) in hemodialysis (HD) patients is thought to be obviously higher than that in the general population. Moreover, IE occurs more likely in HD patients with catheters. With the increase of HD population and extensive use of catheters in HD patients, FE, as a special form of IE, may increase and bring new challenges to clinicians. We reported a case of FE associated with catheter infection in a 44-year-old woman on HD. The risk factors and treatment strategies of FE in HD patients were discussed. © 2017 International Society for Hemodialysis.

    Background: Higher than expected cardiovascular mortality in hemodialysis patients, has been attributed to dyslipidemia as well as inflammation. Beta2-Microglobulin (β2M) is an independent predictor of outcome for hemodialysis patients and a representative substance of middle molecules. Results: In 40 patients in high-flux membrane hemodialysis, we found negative correlation of β2M with high density lipoprotein (r=-0.73, p<0.001) and albumin (r= -0.53, p<0.001) and positive correlation with triglycerides (r=0.69, p<0.001), parathyroid hormone (r=0.58, p < 0.05) and phosphorus (r= 0.53, p<0.001). There was no correlation of β2M with C- reactive protein (CRP) and interleukin-6 (IL-6). During the follow-up period of three years, 6 out of 40 patients have died from cardiovascular events. Conclusion: In high-flux membrane hemodialysis patients, we observed a significant relationship of β2M with dyslipidemia and mineral bone disorders, but there was no correlation with inflammation.

    Sleep disturbance is common in dialysis patients and is associated with the development of enhanced inflammatory responses. Cognitive-behavioral therapy is effective for sleep disturbance and reduces inflammation experienced by peritoneal dialysis patients; however, this has not been studied in hemodialysis patients. To determine whether alleviation of sleep disturbance in hemodialysis patients also leads to less inflammation, we conducted a randomized controlled interventional study of 72 sleep-disturbed hemodialysis patients. Within this patient cohort, 37 received tri-weekly cognitive-behavioral therapy lasting 6 weeks and the remaining 35, who received sleep hygiene education, served as controls. The adjusted post-trial primary outcome scores of the Pittsburgh Sleep Quality Index, the Fatigue Severity Scale, the Beck Depression Inventory, and the Beck Anxiety Inventory were all significantly improved from baseline by therapy compared with the control group. The post-trial secondary outcomes of high-sensitive C-reactive protein, IL-18, and oxidized low-density lipoprotein levels significantly declined with cognitive-behavioral therapy in comparison with the control group. Thus, our results suggest that cognitive-behavioral therapy is effective for correcting disorganized sleep patterns, and for reducing inflammation and oxidative stress in hemodialysis patients.

    The aim of this paper was to investigate the association between appetite and kidney-disease specific quality of life in maintenance hemodialysis patients. Quality of life (QoL) was measured using the kidney disease quality of life survey. Appetite was measured using self-reported categories and a visual analog scale. Other nutritional parameters included Patient-Generated Subjective Global Assessment (PGSGA), dietary intake, body mass index and biochemical markers C-reactive protein and albumin. Even in this well nourished sample (n=62) of hemodialysis patients, PGSGA score (r=-0.629), subjective hunger sensations (r=0.420) and body mass index (r=-0.409) were all significantly associated with the physical health domain of QoL. As self-reported appetite declined, QoL was significantly lower in nine domains which were mostly in the SF36 component and covered social functioning and physical domains. Appetite and other nutritional parameters were not as strongly associated with the Mental Health domain and Kidney Disease Component Summary Domains. Nutritional parameters, especially PGSGA score and appetite, appear to be important components of the physical health domain of QoL. As even small reductions in nutritional status were associated with significantly lower QoL scores, monitoring appetite and nutritional status is an important component of care for hemodialysis patients.

    The incidence of end-stage renal failure is high and it is responsible for the increase of the rate of morbidity and mortality rates among our patients. The objective is to study patient characteristics before starting hemodialysis and to evaluate factors influencing their short and long term survival. This is a prospective study of 127 patients starting hemodialysis between June and December 2001. On May 31, 2005, their survival was analyzed according to different parameters. Patients were 77 males and 50 females. Their mean age was 51.4 +/- 16.1 years (15 to 78 years). Diabetes was observed in 33.9% of cases. Only 70.9% of patients were covered by a social service. Chronic renal failure was diagnosed at the end stage in 34.6% of cases. Before starting hemodialysis, only 4 patients were vaccinated against B hepatitis and arteriovenous fistula were not made in any patients. Pericarditis was observed in 9.4% of patients. Albuminemia was < 35 g/l in 60.5% of patients. First hemodialysis session was programmed in 53.5% of patients and realized urgently in 46.3% of patients. Patients were hemodialysed 4, 8 and 12 hours per week respectively in 16.5%, 15.8% and 67.7% of cases. On May 31, 2005, 35.4% of patients died. Their actuarial survivals at 3 months, 1 year and 4 years were respectively at 87.5%, 79.5% and 64.4%. Acturial survival was bad in patients with pericarditis, diabetes, hemodialysed less than 12 hours/week and when the first hemodialysis session was started urgently. The diagnosis of renal failure was frequently made at end-stage. There are no preparations before starting hemodialysis. We have to reinforce prevention programmes and increase the number of nephrologists and nephrology departments.

    Long-term inappropriate proton pump inhibitors use (PPIs) is a matter of concern because of the risks associated with their long-term use in older patients with chronic conditions. The risk of PPI treatment in hemodialysis patients remains unexplored. We assessed the relationship between the use of PPIs and the risk of death in hemodialysis patients throughout a retrospective multicenter propensity score-matched study. Information about demographic, hemodialysis treatment, laboratory data, and concomitant medication was obtained from the EuCliD database (Fresenius Medical Care). We studied 1776 hemodialysis patients on PPI therapy compared to 466 patients not receiving PPIs. The resulting population comprising 2 groups of 410 matched patients was studied. PPI use was associated with hypomagnesemia (Mg <1.8 mg/dl (0.75 mmol/l); odds ratio [OR] = 2.70, 95% confidence interval [CI] = 1.38-5.27, P  < 0.01). The exposure to PPIs in the full patient cohort was identified as an independent predictor for all-cause mortality in both univariate (HR = 3.16, 95% CI = 1.69-5.90, P  < 0.01) and multivariate (HR = 2.70, 95% CI = 1.38-5.27, P  < 0.01) Cox regression models. Moreover PPI use was identified as a predictor of CV mortality (HR = 1.51, 95% CI = 1.05-2.20, P  = 0.03) Of the 820 patients matched throughout the propensity score analysis, the hazard ratios for all-cause mortality (HR = 1.412, 95% CI = 1.04-1.93, P  = 0.03) and CV mortality (HR = 1.67, 95% CI = 1.03-2.71, P  = 0.04) were higher among patients on PPIs versus those not on PPIs. The study data suggest that the PPI treatment should be regularly monitored and prescribed only when indicated.

    Gastrointestinal bleeding remains the leading cause of morbidity and mortality for patients who need hemodialysis treatment. Our aim was to evaluate patients who needed hemodialysis and presented with bleeding during their hospital stay (uremic bleeding patients). Factors that increased the risk of bleeding and death were evaluated. Additionally, uremic bleeding patients were compared to non-uremic bleeding patients regarding gastrointestinal findings. Fifty-one uremic bleeding patients were compared to two control groups which included uremic (hemodialysis dependent and non-bleeding) and non-uremic (no renal insufficiency and bleeding) patients. NSAIDs and anti-ulcer drug usage were more common in uremic bleeding and in uremic non-bleeding groups, respectively. Dialysis vintage was longer in uremic bleeding group. Comparison of uremic bleeding and non-bleeding uremic patients regarding the usage of ACEI or ARB drugs yielded non-significant results. Acute kidney injury, lower plasma albumin level and high CRP level were significantly increased the risk of mortality in uremic bleeding patients. Hospital stay more than 1 week was the only strong factor for mortality when multivariate analysis was performed. Gastroduodenal and duodenal ulcers were significantly detected in uremic bleeding and non-uremic bleeding patients; respectively. Hemodialysis patients presenting with gastrointestinal bleeding should be evaluated regarding use of prescriptions and efforts should be done in order to shorten their hospital stay and decrease their mortality. Effect of ACEI or ARB drugs should also be evaluated in future studies.

    Protein-energy wasting (PEW) is common and associated with poor outcome in hemodialysis patients. In hemodialysis patients, geriatric nutritional risk index (GNRI) and decoy receptor 3 (DcR3) have been shown as the nutritional and inflammatory markers, respectively. The present study aimed to assess the predictive ability of GNRI and DcR3 for PEW status and long-term outcomes in chronic hemodialysis patients. A prospective cohort of 318 hemodialysis patients was conducted with a median follow-up of 54 months. Malnutrition-inflammation score (MIS) was used as the reference standard for the presence of PEW. Endpoints were cardiovascular and all-cause mortality. Baseline GNRI had a strong negative correlation with DcR3 and MIS score. For patients with age < or ≥60, high DcR3 and low GNRI were independent predictors for the presence of PEW at baseline. At the end of the study, 81 patients died (27 cardiovascular deaths). The adjusted hazard ratios (95% confidence intervals) of low GNRI and high DcR3 were 1.93 (1.1-4.8) and 2.53 (1.2-5.5) for cardiovascular mortality and 1.85 (1.1-3.2) and 2.37 (1.5-3.7) for all-cause mortality, respectively. While integrated into a model of conventional risk factors, GNRI together with DcR3 further significantly improved the predictability for overall mortality (c statistic, 0.823). Low GNRI and high DcR3 were the alternatives for identifying hemodialysis patients at risk of PEW and overall mortality. Further studies are needed to verify whether timely recognition of hemodialysis patients with a high malnutrition-inflammation risk could reduce their mortality by appropriate interventional strategies.

    To identify characteristics of hemodialysis patients most likely to experience difficulty adhering to sodium restrictions associated with their dietary regimen. Secondary analysis using baseline data from an ongoing randomized clinical trial examining the effects of a technology-supported behavioral intervention on dietary sodium intake in hemodialysis patients. Thirteen dialysis centers in southwestern Pennsylvania. We included 122 participants (61% women; 48% African American) aged 61 ± 14 years undergoing maintenance, intermittent hemodialysis for end-stage renal disease. Normalized dietary sodium intake, adjusted interdialytic weight gain, perceived problems, and self-efficacy for restricting dietary sodium. Younger participants were more likely to report problems managing their hemodialysis diet and low self-efficacy for restricting sodium intake. Consistent with these findings, younger participants had a higher median sodium intake and higher average adjusted interdialytic weight gain. Females reported more problems managing their diet. Race, time on dialysis, and perceived income adequacy did not seem to influence outcome measures. Our findings suggest that patients who are younger and female encounter more difficulty adhering to the hemodialysis regimen. Hence, there may be a need to individualize counseling and interventions for these individuals. Further investigation is needed to understand the independent effects of age and gender on adherence to hemodialysis dietary recommendations and perceived self-efficacy.

    Despite the improvement of hemodialysis technique, mortality of chronic hemodialysis patients remains quite high. It considerably depends on dialysis adequacy. The aim of the study was to evaluate the adequacy of hemodialysis procedure and its changes in Lithuania during 1999-2005. Between 1999 and 2005 in December, all hemodialysis centers in Lithuania were annually visited, and data on the type of hemodialysis, duration of hemodialysis (hours per week), single-pool Kt/V were collected from all hemodialysis patients. The percentage of patients on bicarbonate hemodialysis sharply increased from 57.9% in 1999 to 100% in 2001 (P<0.001), and the duration of hemodialysis procedure increased (67.3% of hemodialysis patients were dialyzed 12 and more hours per week in 2005 vs. 41.3% in 1999, P<0.001). The percentage of patients who were dialyzed three times per week increased from 51% in 1999 to 77% in 2005 (P<0.001). The mean Kt/V was 0.81+/-0.53 in 1999, but it increased to 1.21+/-0.27 in 2005 (P<0.001). More than half (54%) of all hemodialysis patients in 2005 had Kt/V > or =1.2 vs. more than one-third (36%) in 1999 (P<0.001). The mean Kt/V of patients who were on dialysis three times per week was 1.25+/-0.6; two times per week, 1.30+/-0.8; and one time per week, 1.27+/-0.26 in 2003. In 2005, the results were 1.21+/-0.27, 1.22+/-0.26, and 1.16+/-0.29, respectively (P>0.05). CONCLUSIONS. 1. The improvement of the quality of hemodialysis was observed in Lithuania during 1999-2005: a) from 2001, patients received only bicarbonate hemodialysis; b) weekly duration of hemodialysis increased; c) Kt/V improved. 2. Despite the improvement of hemodialysis quality, it is not optimal yet and is associated with insufficient duration of hemodialysis.

    Cognitive impairment is common in patients treated with hemodialysis. The trajectory of cognitive function and risk factors for cognitive decline remain uncertain in this population. Longitudinal cohort. 314 prevalent hemodialysis patients. Age, sex, race, education level, hemodialysis vintage, cause of end-stage renal disease, and baseline history of cardiovascular disease. Cognitive function as determined by a comprehensive neurocognitive battery, administered at baseline and yearly when possible. Individual cognitive test results were reduced into 2 domain scores using principal components analysis, representing memory and executive function, which were used as our coprimary outcomes and by definition have a mean of zero and SD of 1. Mean age was 63 years; 54% were men, 22% were black, and 90% had at least a high school education. During a median follow-up of 2.1 (IQR, 0.9-4.2) years, 196 had at least 1 follow-up test, 156 died, and 43 received a kidney transplant. Linear mixed models and joint models, which accounted for competing risks from death, dropout, or kidney transplantation, showed nearly identical results. The joint model demonstrated a decline in executive function (-0.09 [95% CI, -0.13 to -0.05] SD per year), whereas memory improved slightly (0.05 [95% CI, 0.02 to 0.08] SD per year). A significant yearly decline was also seen in the Mini-Mental State Examination score (median change, -0.41; 95% CI, -0.57 to -0.25). Older age was the only significant risk factor for steeper executive function decline (-0.04 [95% CI, -0.06 to -0.02] SD steeper annual decline for each 10 years of age). Prevalent hemodialysis patients only, limited follow-up testing due to high mortality rate, and exclusion of participants with severe cognitive deficits or dementia. Prevalent hemodialysis patients demonstrate significant cognitive decline, particularly within tests of executive function. Older age was the only statistically significant risk factor for steeper

    We reported previously that muscle quality and muscle strength provide clinically relevant predictors for better survival in hemodialysis patients. Iron overload might impair muscle function by its accumulation in muscle in such patients. Serum ferritin, a marker for body iron store, was examined for its association with handgrip strength (HGS) and muscle quality which was defined as the ratio of HGS to arm lean mass measured with dual-energy X-ray absorptiometry. In 300 Japanese hemodialysis patients, age, hemodialysis duration, body mass index, and serum albumin were 58.0 ±12.0 (mean ± standard deviation) years, 4.2 (1.8-10.4) (median [25th-75th percentile]) years, 20.4 ± 2.8 kg/m(2), 4.0 ± 0.3 g/dL, respectively. Hemoglobin and hematocrit were 8.9 ± 1.2 g/dL, and 28.8 ± 3.9%, respectively, whereas transferrin saturation and serum ferritin were 29.8 ± 11.0% and 100 (54-172) ng/mL, respectively. Serum ferritin significantly correlated in a positive manner with the total dose of iron orally administered during the previous 6 months (r = 0.185, P = .0013). HGS and muscle quality were 23.1 ± 10.4 kg and 11.6 ± 3.8 kg/kg, respectively. In multivariate analysis to elucidate the factors associated with HGS and muscle quality in 300 hemodialysis patients, which included transferrin saturation and log serum ferritin, in addition to age, gender, hemodialysis duration, the presence/absence of diabetes, body mass index as independent variables, log serum ferritin emerged as a significant and independent factor which associated in a negative fashion with HGS (β = -0.091, P = .0395) and tendency toward negative association with muscle quality (β = -0.100, P = .0754). In summary, the present study demonstrated the significant association of serum ferritin with HGS and muscle quality in hemodialysis patients and thus suggested that we should be careful of iron overload to avoid its possible harmful effect on muscle in such patients.

    Objective To document the prevalence of patients on hemodialysis in southwestern Guatemala who have chronic kidney disease (CKD) of non-traditional causes (CKDnt). Methods This cross-sectional descriptive study interviewed patients on hemodialysis at the Instituto Guatemalteco de Seguridad Social on their health and occupational history. Laboratory serum, urine and vital sign data at the initiation of hemodialysis were obtained from chart reviews. Patients were classified according to whether they had hypertension or obesity or neither. The proportion of patients with and without these traditional CKD risk factors was recorded and the association between demographic and occupational factors and a lack of traditional CKD risk factors analyzed using multivariate logistic regression. Results Of 242 total patients (including 171 non-diabetics) enrolled in hemodialysis in southwestern Guatemala, 45 (18.6% of total patients and 26.3% of non-diabetics) lacked traditional CKD risk factors. While agricultural work history was common, only travel time greater than 30 minutes and age less than 50 years old were significantly associated with CKD in the absence of traditional risk factors. Individuals without such risk factors lived throughout southwestern Guatemala's five departments. Conclusions The prevalence of CKDnT appears to be much lower in this sample of patients receiving hemodialysis in Southwestern Guatemala than in hospitalized patients in El Salvador. It has yet to be determined whether the prevalence is higher in the general population and in patients on peritoneal dialysis.

    Different factors can contribute to a sedentary lifestyle among hemodialysis (HD) patients, including the period they spend on dialysis. The aim of this study was to evaluate characteristics of physical activities in daily life in this population by using an accurate triaxial accelerometer and to correlate these characteristics with physiological variables. Nineteen HD patients were evaluated using the DynaPort accelerometer and compared to nineteen control individuals, regarding the time spent in different activities and positions of daily life and the number of steps taken. HD patients were more sedentary than control individuals, spending less time walking or standing and spending more time lying down. The sedentary behavior was more pronounced on dialysis days. According to the number of steps taken per day, 47.4% of hemodialysis patients were classified as sedentary against 10.5% in control group. Hemoglobin level, lower extremity muscle strength, and physical functioning of SF-36 questionnaire correlated significantly with the walking time and active time. Looking accurately at the patterns of activity in daily life, HDs patients are more sedentary, especially on dialysis days. These patients should be motivated to enhance the physical activity.

    Patients on hemodialysis frequently experience pain and may be particularly vulnerable to opioid-related complications. However, data evaluating the risks of opioid use in patients on hemodialysis are limited. Using the US Renal Data System, we conducted a cohort study evaluating the association between opioid use (modeled as a time-varying exposure and expressed in standardized oral morphine equivalents) and time to first emergency room visit or hospitalization for altered mental status, fall, and fracture among 140,899 Medicare-covered adults receiving hemodialysis in 2011. We evaluated risk according to average daily total opioid dose (>60 mg, ≤60 mg, and per 60-mg dose increment) and specific agents (per 60-mg dose increment). The median age was 61 years old, 52% were men, and 50% were white. Sixty-four percent received opioids, and 17% had an episode of altered mental status (15,658 events), fall (7646 events), or fracture (4151 events) in 2011. Opioid use was associated with risk for all outcomes in a dose-dependent manner: altered mental status (lower dose: hazard ratio, 1.28; 95% confidence interval, 1.23 to 1.34; higher dose: hazard ratio, 1.67; 95% confidence interval, 1.56 to 1.78; hazard ratio, 1.29 per 60 mg; 95% confidence interval, 1.26 to 1.33), fall (lower dose: hazard ratio, 1.28; 95% confidence interval, 1.21 to 1.36; higher dose: hazard ratio, 1.45; 95% confidence interval, 1.31 to 1.61; hazard ratio, 1.04 per 60 mg; 95% confidence interval, 1.03 to 1.05), and fracture (lower dose: hazard ratio, 1.44; 95% confidence interval, 1.33 to 1.56; higher dose: hazard ratio, 1.65; 95% confidence interval, 1.44 to 1.89; hazard ratio, 1.04 per 60 mg; 95% confidence interval, 1.04 to 1.05). All agents were associated with a significantly higher hazard of altered mental status, and several agents were associated with a significantly higher hazard of fall and fracture. Opioids were associated with adverse outcomes in patients on hemodialysis, and this risk

    Poor adherence to treatment is common in patients on hemodialysis which may increase risk for poor clinical outcomes and mortality. Self management interventions have been shown to be effective in improving compliance in other chronic populations. The aim of this trial is to evaluate the effectiveness of a recently developed group based self management intervention for hemodialysis patients compared to standard care. This is a multicentre parallel arm block randomized controlled trial (RCT) of a four session group self management intervention for hemodialysis patients delivered by health care professionals compared to standard care. A total of 176 consenting adults maintained on hemodialysis for a minimum of 6 months will be randomized to receive the self management intervention or standard care. Primary outcomes are biochemical markers of clinical status and adherence. Secondary outcomes include general health related quality of life, disease-specific quality of life, mood, self efficacy and self-reported adherence. Outcomes will be measured at baseline, immediately post-intervention and at 3 and 9 months post-intervention by an independent assessor and analysed on intention to treat principles with linear mixed-effects models across all time points. A qualitative component will examine which aspects of program participants found particularly useful and any barriers to change. The NKF-NUS intervention builds upon previous research emphasizing the importance of empowering patients in taking control of their treatment management. The trial design addresses weaknesses of previous research by use of an adequate sample size to detect clinically significant changes in biochemical markers, recruitment of a sufficiently large representative sample, a theory based intervention and careful assessment of both clinical and psychological endpoints at various follow up points. Inclusion of multiple dependent variables allows us to assess the broader impact on the intervention

    Native arteriovenous fistula (AVF) represents the best vascular approach for chronic hemodialysis. The aim of this study was to determine the survival of the first AVF and to identify the factors responsible for poor AVF survival. A retrospective study was conducted on 96 chronic hemodialysis patients benefiting from the creation and cannulation of their first AVF at our center, with a minimum follow-up period of 1 year. We collected demographic, clinical, and biological data, as well as analyzed the following AVF characteristics: anatomic site, cannulation time, survival, and complications. To identify the predictive factors of poor AVF survival, we defined and compared two groups of patients on the basis of whether they lost their first AVF during the evolution. Patients' mean age was 42.1 ± 13 years, with predominantly female patients. Mean AVF cannulation time was 17.5 ± 24 days. AVF loss was mainly related to thrombosis in 29% of the cases and stenosis in 9.4%. AVF survival was 87%, 77%, 71%, 67%, and 64% after 1, 3, 5, 8, and 10 years of hemodialysis, respectively. In our study, the main factors associated with AVF loss were lengthy jugular venous catheters placement (p = 0.004), short AVF cannulation time after its creation (p = 0.03), and hypotension episodes during dialysis (p = 0.03). Long-term survival and quality of life in hemodialysis depend on an appropriate dialysis carried out-thanks to a correct vascular approach! According to the previously published data, survival of the first AVF can vary between 10% and 36% at 10 years. In our study, survival of the first native AVF was satisfying because it reached 64% at 10 years. Early AVF creation and prevention and management of its complications remain the safest and most comfortable solution to ensure AVF survival and thus a satisfying survival and quality of life in chronic hemodialysis patients.

    Autosomal dominant polycystic kidney disease is the most common hereditary renal disease in humans. To examine the prevalence, clinical and laboratory characteristics of patients with polycystic kidneys and relate disease manifestations by gender. This was an observational and retrospective study. All the medical records of patients with polycystic kidneys who initiated hemodialysis between 1995 and 2012, in four centers that treat patients of the coverage area of the 15th regional health Paraná (Brazil), were analyzed. The study included 48 patients with polycystic kidneys, the primary cause of stage 5 CKD. Disease prevalence was one in 10,912 people. The average age of dialysis initiation was 50.7 years and the follow-up time on dialysis until transplantation (36.5 months) was lower among men. Hypertension was the most frequent diagnosis in 73% of patients, predominantly in women (51.4%). The liver cyst was the most frequent extrarenal manifestations in men (60.0%). The death occurred in 10.4% of patients using hemodialysis, and 60% of men. The class of antihypertensive drug used was that acts on the renin-angiotensin system with higher frequency of use among women (53.3%). The post-dialysis urea was significantly higher in men. The prevalence of the disease is low among hemodialysis patients in southern Brazil. The differences observed between genders, with the exception of the post-dialysis urea, were not significant. The findings are different from those reported in North America and Europe.

    Objective To test the performance of appetite assessment tools among patients receiving hemodialysis. Design Cross-sectional. Setting Seven dialysis facilities in Northern California. Subjects 221 patients receiving hemodialysis. Intervention We assessed five appetite assessment tools [self-assessment of appetite, subjective assessment of appetite, visual analogue scale (VAS), Functional Assessment of Anorexia/Cachexia Therapy (FAACT) score and the Anorexia Questionnaire (AQ)]. Main outcome measures Reported food intake, normalized protein catabolic rate (nPCR), and change in body weight were used as criterion measures, and we assessed associations among the appetite tools and biomarkers associated with nutrition and inflammation. Patients were asked to report their appetite and the percentage of food eaten (from 0% to 100%) during the last meal compared to usual intake. Results Fifty-eight (26%) patients reported food intake ≤50% (defined as poor appetite). The prevalence of anorexia was 12% by self-assessment of appetite, 6% by subjective assessment of appetite, 24% by VAS, 17% by FAACT score, and 12% by AQ. All tools were significantly associated with food intake ≤50% (p<0.001), except self-assessment of appetite. The FAACT score and the VAS had the strongest association with food intake ≤50% (c-statistic 0.80 and 0.76). Patients with food intake ≤50% reported weight loss more frequently than patients without low intake (36% vs 22%) and weight gain less frequently (19% vs 35%; p=0.03). nPCR was lower among anorexic patients based on the VAS (1.1 ± 0.3 vs 1.2 ± 0.3, p=0.03). Ln IL-6 correlated inversely with food intake (p=0.03), but neither IL-6 nor CRP correlated with any of the appetite tools. Furthermore, only the self-assessment of appetite was significantly associated with serum albumin (p=0.02), prealbumin (p=0.02) and adiponectin concentrations (p=0.03). Conclusions Alternative appetite assessment tools yielded widely different estimates of the

    Insomnia is a problem often experienced by patients on chronic dialysiswhich reduces their quality of life. Current management of insomnia with this specific group of patients has yet to produce optimum results. In this study, we explored the roleof acupuncture as a treatment for symptoms of insomnia in patients on chronic dialysis. Twenty-eight hemodialysis patients suffering from insomnia were divided randomly into two groups, an acupuncture group (n = 15) who received acupuncture treatment at the points HT7 Shenmen, PC6 Neiguan, GV20 Baihui, and EX-HN1 Sishenchong, anda control group (n = 13) who underwenta sham procedure in which a needle was inserted into an elastic bandage at the same points. The acupuncture treatment was done during hemodialysis twice a week for five weeks. PSQI scores and the WHOQOL-BREF were assessed before treatment, after the fifth treatment, and at the end of the treatment. Significant differences were found in the PSQI score ((4.20±2.27 vs. 11.23±3.37) p = 0.000) and in the WHOQOL-BREF ((94.53±10.08 vs. 82.69±11.90) p = 0.008) between the acupuncture group and the control group by the end of the period of treatment. Acupuncture treatment effectively improved the quality of sleep and the quality of life for these chronic hemodialysis patients.

    Multiple observational studies along with a limited number of randomized clinical trials suggest that intensive hemodialysis (IHD) not only improves outcomes for uremic patients undergoing chronic dialysis but does so with a more favorable cost/benefit ratio compared with conventional hemodialysis. As a result of this, there has been a rapid increase in the interest in home hemodialysis (HHD) as HHD represents the easiest means of implementing IHD. While HHD has generated increased interest given its association with better outcomes/reduced hospitalizations, there are very few randomized controlled trials comparing HHD with other hemodialysis methods. Reported HHD-associated increased survival benefits compared with in-center hemodialysis are from uncontrolled studies, which raise patient selection bias as underlying the differences found. Thus, while HHD draws increasing attention, studies that pay careful attention to the psychosocial, demographic, and clinical factors associated with patients selected to undergo HHD will be needed to ultimately demonstrate its benefits, clarify the clinical applications, and determine the limits of IHD use in dialysis patients.

    Dermatologic complications are common in patients with end-stage renal disease and also have a high diversity. This meta-analysis reviews prevalence of dermatological manifestations among hemodialysis patients in Iran. Using PubMed and NLM Gateway (for MEDLINE), Institute of Scientific Information (ISI), and SCOPUS as the main international electronic data sources, and Iran-Medex, Irandoc, and Scientific Information Database, as the main domestic databases with systematic search capability, we systematically searched surveys, papers, and reports on the prevalence of dermatological manifestations (until February 2016). Heterogeneity of reported prevalence's between studies was assessed using the Q test; overall prevalence of dermatological manifestations was estimated using random-effect meta-analysis model. We found 1229 records; from them, a total of eight studies comprising 917 hemodialysis patients were included. In all of studies, skin discoloration, pruritus and xerosis have the highest prevalence. According to random-effect meta-analysis model, the pooled prevalence of skin discoloration, pruritus, ecchymosis, xerosis, and half-and-half nail in hemodialysis patients were 48.03% (95% CI: 45.09-51.01), 52.85% (95%CI: 49.23-56.47), 19.88 (95% CI: 17.57-22.19), 51.14% (95% CI: 48.25-54.02), and 18.50% (95% CI: 16.0-21.0), respectively. his study shows that the prevalence of dermatological manifestations seems high among the hemodialysis patients in Iran, and skin discoloration, pruritus, and xerosis are more common. © 2018 Wiley Periodicals, Inc.

    Patients with end stage renal disease often fail to follow prescribed dietary and fluid regimen, leading to undesirable outcomes. This study aimed to examine and identify factors influencing dietary, fluid, medication and dialysis compliance behaviours in patients undergoing hemodialysis. This was a cross-sectional study which employed purposive sampling design. A total of 188 respondents were recruited from 14 dialysis centres in Malaysia between 2008-2011. Self-reported compliance behaviours and biochemical measurements were used as evaluation tools. Compliance rates of dietary, fluid, medication and dialysis were 27.7%, 24.5%, 66.5% and 91.0%, respectively. Younger, male, working patients and those with longer duration on hemodialysis were found more likely to be non-compliant. Lacks of adequate knowledge, inadequate self-efficacy skills, forgetfulness and financial constraints were the major perceived barriers towards better compliance to fluid, dietary, medication and dialysis, respectively. Healthcare professionals should recognise the factors hindering compliance from the patients' perspective while assisting them with appropriate skills in making necessary changes possible.

    Depression and anxiety are prevailing mental problem in patients on chronic hemodialysis and they have great influence on outcome of illness. Additionally, these disorders are rarely identified in that population of patients and they are insufficiently treated. The aim of this study was to assess the prevalence of depression and anxiety in patients on chronic hemodialysis in University Clinical Hospital Mostar and to examine the correlation between the demographic variables and the time spent on dialysis with depression and anxiety levels. The experimental group consisted of 56 patients on chronic hemodialysis in Mostar Clinical Hospital. The control group 1 consisted of 53 patients diagnosed with a chronic illness and treated for at least a year, while the control group 2 consisted of 51 persons who were not diagnosed with any chronic somatic or mental illness. Demographic data were collected using the constructed questionnaire. The Beck Depression Inventory-BDI was used to determine depression, while the Spielberger State-Trait Anxiety Inventory-STAI was used to determine anxiety. We recorded significantly higher prevalence of depression in patients on chronic dialysis (51.8%) than in patients with a chronic illness (41.5%) and persons without chronic illnesses (9.8%; p < 0.001). Trait anxiety level was significantly higher in hemodialysed patients compared to the other two groups (p = 0.006) but there were no significant differences in state anxiety level. The study has not shown any significant difference in the prevalence of depression and anxiety level regarding the differences in sex, gender and education level, apart from a higher level of state anxiety in patients with a lower education level (p = 0.032). These results indicate that patients on hemodialysis have a significantly higher level of depression and a higher level of trait anxiety compared to patients with chronic illnesses and especially compared to general population.

    This study sought to determine the effects of lavender aromatherapy on pain following needle insertion into a fistula in patients undergoing hemodialysis. This is a randomized controlled clinical trial in which 92 patients undergoing hemodialysis with arteriovenous fistulas were randomly divided into two groups. The experimental-group patients inhaled lavender essence with a concentration of 10% for 5 min during 3 hemodialysis sessions, while the control-group patients received aromatherapy free of lavender essence. The mean VAS pain intensity score in the experimental and control groups before the intervention was 3.78 ± 0.24 and 4.16 ± 0.32, respectively (p = 0.35). The mean VAS pain intensity score in the experimental and control groups after three aromatherapy sessions was 2.36 ± 0.25 and 3.43 ± 0.31, respectively (p = 0.009). Lavender aromatherapy may be an effective technique to reduce pain following needle insertion into a fistula in hemodialysis patients. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Serum magnesium (Mg) levels have been associated with muscle performance in the general population. We hypothesized that serum Mg would be associated with muscle quality in hemodialysis patients. A total of 310 patients were examined (age: 58 ± 12 years, hemodialysis duration: 6.4 ± 6.0 years, 60.6% men, and 36.1% diabetics). Arm lean mass was measured by dual energy X-ray absorptiometry (DXA) on the dominant side. Arm muscle quality was defined as the ratio of the handgrip strength to the arm lean mass of the same side (kg/kg). Serum Mg was 1.15 ± 0.16 mmol/L (2.8 ± 0.4 mg/dL), being higher than the reference range of normal subjects. There was a significant negative correlation between muscle quality and age (r = -0.326, p<0.0001) and duration of hemodialysis (r = -0.253, p<0.0001). The muscle quality of the diabetics was significantly lower than that of the non-diabetics (p<0.001). There was a significant, positive correlation between muscle quality and serum Mg (r = 0.118, p<0.05), but not serum calcium or phosphate. In multiple regression analysis, age, gender, hemodialysis duration, diabetes, and serum Mg (β = 0.129, p<0.05) were significantly and independently associated with muscle quality (R(2) = 0.298, p<0.0001). These results demonstrated that a lower serum Mg concentration was significantly associated with poor muscle quality in hemodialysis patients. Further studies are needed to explore the mechanism by which lower serum Mg affects muscle quality.

    The purpose of this study is to evaluate the accuracy of a noninvasive radiofrequency-based device, the Cardio-Pulmonary Stethoscope (CPS), to monitor heart and respiration rates, and detect changes in lung water content in human experiments and clinical trials. Three human populations (healthy subjects ( ), heart failure (), and hemodialysis () patients) were enrolled in this study. The study was conducted at the University of Hawaii and the Queen's Medical Center in Honolulu, HI, USA. Measurement of heart and respiration rates for all patients was compared with standard FDA - approved monitoring methods. For lung water measurements, CPS data were compared with simultaneous pulmonary capillary wedge pressure (PCWP) measurements for heart failure patients, and with change in weight of extracted fluid for hemodialysis patients. Statistical correlation methods (Pearson, mixed, and intraclass) were used to compare the data and examine accuracy of CPS results. Results show that heart and respiration rates of all patients have excellent correlation factors, r≥0.9. Comparisons with fluid removed during hemodialysis treatment showed correlation factor of to 1, while PCWP measurements of heart failure patients had correlation factor of to 0.97. These results suggest that CPS technology accurately quantifies heart and respiration rates and measure fluid changes in the lungs. The CPS has the potential to accurately monitor lung fluid status noninvasively and continuously in a clinical and outpatient setting. Early and efficient management of lung fluid status is key in managing chronic conditions such heart failure, pulmonary hypertension, and acute respiration distress syndrome.

    Leptin is secreted by adipose tissue and decreases appetite. However, the role of leptin in the pathogenesis of hemodialysis (HD)-related malnutrition has not been fully evaluated. The aim of study was to investigate the association between the serum leptin levels, serum C-reactive protein (CRP) levels, and nutritional status in hemodialysis patients. This analytical descriptive study included 45 hemodialysis patients and 40 healthy subjects. Biochemical parameters and serum leptin levels were measured. The nutritional status was evaluated using a food frequency questionnaire (FFQ) and the calculation of the body mass index (BMI). Serum leptin (P < 0.05) and albumin (P < 0.0001) levels and BMI (P < 0.001) of HD patients were significantly lower, while CRP levels were significantly higher than those of controls (P < 0.0001). HD patients consumed the lower daily servings of the food groups compared to the control subjects (P < 0.0001). A significant positive correlation between serum levels of leptin and albumin and BMI was demonstrated. No significant correlations were identified between leptin level, CRP level, and other variables. The findings suggest that low levels of leptin may be a contributory factor for malnutrition in HD patients. Further studies are required to ascertain the significance of leptin levels in relation to nutritional factors in hemodialysis patients.

    This study set out to explore the experience of food cravings and thirst, and their management strategies in patients on hemodialysis. Semi-structured interviews with N = 32 hemodialysis patients were analyzed thematically. Findings indicated that food cravings and thirst were common in everyday life of patients and resulted in different emotional responses. A combination of cognitive and behavioral strategies was employed, including avoidance, controlled consumption, and substitution. Self-monitoring and compensatory strategies were also used to prevent or compensate for lapses. These findings lay the groundwork for future work aimed to improve adherence in end-stage renal disease patients. © The Author(s) 2014.

    Patients on long-term hemodialysis become deficient in carnitine and are frequently treated with carnitine supplementation to offset their renal anemia, lipid abnormality and cardiac dysfunction. The therapeutic value of carnitine supplementation on left ventricular hypertrophy (LVH) in patients with normal cardiac systolic function remains uncertain. The cardiac morphology and function of 10 patients given 10 mg/kg of L-carnitine orally, immediately after hemodialysis sessions 3 times per week for a 12-month period were compared with 10 untreated control patients. Using echocardiography, left ventricular fractional shortening (LVFS) and left ventricular mass index (LVMI) were measured before and after the study period. As a result, amounts of serum-free carnitine increased from 28.4+/-4.7 to 58.5+/-12.1 micromol/L. The LVMI decreased significantly from 151.8+/-21.2 to 134.0+/-16.0 g/m(2) in treated patients (p<0.01), yet the LVMI in untreated control patients did not change significantly (ie, from 153.3+/-28.2 to 167.1+/-43.1 g/m(2)). However, LVFS values remained unchanged in both groups. Although L-carnitine promoted a 31% reduction in erythropoietin requirements, hematocrit and blood pressure did not change during the study period. Supplementation with L-carnitine induced regression of LVH in patients on hemodialysis, even for those with normal systolic function.

    The effect of maintenance intravenous (IV) iron administration on subsequent achievement of anemia management goals and mortality among patients recently initiating hemodialysis is unclear. We performed an observational cohort study, in adult incident dialysis patients starting on hemodialysis. We defined IV administration strategies over a 12-week period following a patient's initiation of hemodialysis; all those receiving IV iron at regular intervals were considered maintenance, and all others were considered non-maintenance. We used multivariable models adjusting for demographics, clinical and treatment parameters, iron dose, measures of iron stores and pro-infectious and pro-inflammatory parameters to compare these strategies. The outcomes under study were patients' (i) achievement of hemoglobin (Hb) of 10-12 g/dL, (ii) more than 25% reduction in mean weekly erythropoietin stimulating agent (ESA) dose and (iii) mortality, ascertained over a period of 4 weeks following the iron administration period. Maintenance IV iron was administered to 4511 patients and non-maintenance iron to 8458 patients. Maintenance IV iron administration was not associated with a higher likelihood of achieving an Hb between 10 and 12 g/dL {adjusted odds ratio (OR) 1.01 [95% confidence interval (CI) 0.93-1.09]} compared with non-maintenance, but was associated with a higher odds of achieving a reduced ESA dose of 25% or more [OR 1.33 (95% CI 1.18-1.49)] and lower mortality [hazard ratio (HR) 0.73 (95% CI 0.62-0.86)]. Maintenance IV iron strategies were associated with reduced ESA utilization and improved early survival but not with the achievement of Hb targets. © The Author 2016.

    Background and objectives Indoxyl sulfate, a protein-bound uremic toxin, may be associated with cardiovascular events and mortality in patients with CKD. This study aimed to investigate the relationship between indoxyl sulfate and heart failure in patients on hemodialysis. Design, setting, participants, & measurements Patients on hemodialysis for >6 months were enrolled within 6 months. Patients with congestive heart failure, angina pectoris, acute myocardial infarction, cerebral infarction, or cerebral hemorrhage within 3 months before the study or those <18 years old were excluded. The primary end point was first heart failure event during follow-up. Results In total, 258 patients (145 men) with a mean age of 57.0±14.6 years old were enrolled. Median plasma indoxyl sulfate level was used to categorize patients into two groups: the low-indoxyl sulfate group (indoxyl sulfate ≤32.35 μg/ml) and the high-indoxyl sulfate group (indoxyl sulfate >32.35 μg/ml). Then, patients were prospectively followed up for a median of 48.0 (interquartile range: 33.5–48.0) months. During follow-up, 68 patients experienced episodes of first heart failure. Kaplan–Meier analysis revealed the incidence of first heart failure event in the high–indoxyl sulfate group was significantly higher than in the low-indoxyl sulfate group (log rank P<0.001). Cox regression analysis showed indoxyl sulfate was significantly associated with first heart failure event (indoxyl sulfate as the continuous variable: hazard ratio, 1.02; 95% confidence interval [95% CI], 1.01 to 1.03; P=0.001; indoxyl sulfate as the dichotomous variable: hazard ratio, 3.49; 95% CI, 1.97 to 6.20; P<0.001). After adjustment for other confounding factors, the results remained significant (indoxyl sulfate as the continuous variable: hazard ratio, 1.04; 95% CI, 1.02 to 1.06; P<0.001; indoxyl sulfate as the dichotomous variable: hazard ratio, 5.31; 95% CI, 2.43 to 11.58; P<0.001).

    Background and objectives Supraventricular arrhythmias are associated with high morbidity and mortality. Nevertheless, this condition has received little attention in patients on hemodialysis. The objective of this study was to analyze the incidence of intradialysis supraventricular arrhythmia and its long–term prognostic value. Design, setting, participants, & measurements We designed an observational and prospective study in a cohort of patients on hemodialysis with a 10-year follow-up period. All patients were recruited for study participation and were not recruited for clinical indications. The study population comprised 77 patients (42 men and 35 women; mean age =58±15 years old) with sinus rhythm monitored using a Holter electrocardiogram over six consecutive hemodialysis sessions at recruitment. Results Hypertension was present in 68.8% of patients, and diabetes was present in 29.9% of patients. Supraventricular arrhythmias were recorded in 38 patients (49.3%); all of these were short, asymptomatic, and self-limiting. Age (hazard ratio, 1.04 per year; 95% confidence interval, 1.00 to 1.08) and right atrial enlargement (hazard ratio, 4.29; 95% confidence interval, 1.30 to 14.09) were associated with supraventricular arrhythmia in the multivariate analysis. During a median follow-up of 40 months, 57 patients died, and cardiovascular disease was the main cause of death (52.6%). The variables associated with all-cause mortality in the Cox model were age (hazard ratio, 1.04 per year; 95% confidence interval, 1.00 to 1.08), C-reactive protein (hazard ratio, 1.04 per 1 mg/L; 95% confidence interval, 1.00 to 1.08), and supraventricular arrhythmia (hazard ratio, 3.21; 95% confidence interval, 1.29 to 7.96). Patients with supraventricular arrhythmia also had a higher risk of nonfatal cardiovascular events (hazard ratio, 4.32; 95% confidence interval, 2.11 to 8.83) and symptomatic atrial fibrillation during follow-up (hazard ratio, 17.19; 95% confidence interval, 2

    The mean age of starting hemodialysis (HD) in patients with end-stage renal failure is gradually increasing in Japan. It is not uncommon for HD to be commenced in bedridden elderly patients who cannot give informed consent, because of brain damage. However, we have not been able to provide useful advice to their families because there was no relevant information available about the prognosis of bedridden patients on HD. Therefore, we examined the prognosis of bedridden HD patients. Two hundred and nineteen patients who received HD were enrolled. These subjects were divided into five groups; (aged <50, 50-59, 60-69, 70-79, and >or=80 years at the commencement of HD), and we compared the overall prognosis between bedridden and nonbedridden patients, as well as that for each age group. There were 76 bedridden patients among the 219 HD patients, and the main cause of their bedridden state before starting HD was cerebrovascular disease. The 50% survival time after the start of HD was 120 months for the nonbedridden patients versus 56 months for bedridden patients. However, the mean (+/-SD) age of the bedridden patients was higher than that of nonbedridden patients (70 +/- 13 versus 64 +/- 14 years). In patients under age 50 years at the start of dialysis, the survival rate was lower in the bedridden than in the nonbedridden patients, but there were no differences between survival rates for bedridden and nonbedridden patients in the other four age groups. The prognosis of HD patients is poor compared with the general life expectancy of the Japanese population, but whether these patients are bedridden or not has little influence on their survival.

    Fatigue is one problem that is seen in high numbers in hemodialysis patients. Fatigue decreases quality of life by negatively affecting an individual's daily performance, activities, professional life, relations with family and friends, and treatment process. This study was carried out to determine the effect of acupressure on the level of fatigue in hemodialysis patients. The study was conducted as experimental research with an acupressure (intervention) group and a control group. The research, for which an ethics committee's approval and institutional permission was obtained, was conducted in two central provinces of Turkey, Nevşehir and Aksaray, at two hemodialysis centers with similar characteristics. The research was completed with a total of 118 participants (52 in the intervention group and 66 in the control group) who met the inclusion criteria. A total of 12 acupressure sessions, 3 ×/wk for 1 mo, were performed for all participants in the intervention group, as required by the acupressure application protocol, applying acupressure at the Stomach 36 (ST-36), Gallbladder 34 (GB-34), Spleen 6 (SP-6), and Kidney 1 (K-1) acupuncture points with a transcutaneous electrical nerve stimulation (TENS) acupuncture pen (XFT-320 acupuncture pen, Shenzhen Xunfegtong Electronics Co, Ltd, Shenzhen, China). A visual analog scale (VAS) for fatigue and the Piper Fatigue Scale (PFS) were used to evaluate the fatigue level of the participants before and after the acupressure application. After the acupressure applications for 1 mo, the subscale and total fatigue scores for the VAS (P < .001) and PFS were lower (P < .05) for participants in the intervention group compared to the controls, except for the cognitive subscale on the PFS (P < .05). The study found that acupressure, applied using an acupuncture pen, was effective in decreasing fatigue in hemodialysis patients. Based on this result, the current research team suggests that hemodialysis patients and nurses should be

    Cardiovascular disease is the most inducer of morbidity and mortality of chronic kidney disease (CKD) patients who have undergone dialysis. Today, neutrophil to lymphocyte ratio (NLR) is considered an indicator of the severity and extent of systemic inflammation and atherosclerosis in patients with renal and cardiovascular disorders. To examine the relationship between NLR with PAD in regular hemodialysis patients, a cross-sectional study, Ankle- Brachial Index (ABI) measurement and peripheral blood examination was on 72 regular hemodialysis patients ≥6 months. The ABI value ≤0.9 is considered PAD. NLR≥ 3.5 is considered abnormal based on some pre-existing research. Prevalence of PAD is 29.16%. Chi- square test showed significant correlation between NLR with PAD (p = 0.0001), multiplication of Calcium and Phosphorus (p = 0.0001), and type 2 Diabetes Mellitus (T2DM) (p = 0.039), multivariate analysis showed that NLR was an independent predictor for PAD in regular hemodialysis patients (RR = 2.271 p = 0.027). In conclusion, NLR, a new inflammatory marker of peripheral blood examination may serve as a marker of PAD in a regular hemodialysis patient, in addition to the multiplication of Calcium and Phosphorus as well as T2DM.

    Home hemodialysis has been a therapeutic option for almost 4 decades. The complexity of dialysis equipment has been a factor-limiting adoption of this modality. We performed a feasibility study to demonstrate the safety of center-based vs. home-based daily hemodialysis with the NxStage System One portable hemodialysis device. We also performed a retrospective analysis to determine if clinical effects previously associated with short-daily dialysis were also seen using this novel device. We conducted a prospective, 2-treatment, 2-period, open-label, crossover study of in-center hemodialysis vs. home hemodialysis in 32 patients treated at 6 U.S. centers. The 8-week In-Center Phase (6 days/week) was followed by a 2-week transition period and then followed by the 8-week Home Phase (6 days/week). We retrospectively collected data on hemodialysis treatment parameters immediately preceding the study in a subset of patients. Twenty-six out of 32 patients (81%) successfully completed the study. Successful delivery of at least 90% of prescribed fluid volume (primary endpoint) was achieved in 98.5% of treatments in-center and 97.3% at home. Total effluent volume as a percentage of prescribed volume was between 94% and 100% for all study weeks. The composite rate of intradialytic and interdialytic adverse events per 100 treatments was significantly higher for the In-Center Phase (5.30) compared with the Home Phase (2.10; p=0.007). Compared with the period immediately preceding the study, there were reductions in blood pressure, antihypertensive medications, and interdialytic weight gain. Daily home hemodialysis with a small, easy-to-use hemodialysis device is a viable dialysis option for end-stage renal disease patients capable of self/partner-administered dialysis.

    Cardiovascular disease is a major concern for patients with end-stage renal disease (ESRD), especially those on hemodialysis. ESRD patients with coronary artery disease often do not have symptoms or present with atypical symptoms. Coronary lesions in ESRD patients are characterized by increased media thickness, infiltration and activation of macrophages, and marked calcification. Several studies showed worsened clinical outcomes after coronary revascularization, which were dependent on the severity of renal dysfunction. ESRD patients on hemodialysis have the most severe renal dysfunction; thus, the clinical outcomes are worse in these patients than in those with other types of renal dysfunction. Medications for primary or secondary cardiovascular prevention are also insufficient in ESRD patients. Efficacy of drug-eluting stents is inferior in ESRD patients, compared to the excellent outcomes observed in patients with normal renal function. Unsatisfactory outcomes with trials targeting cardiovascular disease in patients with ESRD emphasize a large potential to improve outcomes. Thus, optimal strategies for diagnosis, prevention, and management of cardiovascular disease should be modified in ESRD patients. PMID:29515692

    Infection is the most common cause of death in hemodialysis patients, after cardiovascular disease. Dialysis access infections, with secondary septicemia, contribute significantly to patient mortality. The most common source is temporary catheterization. Bacteremia occurs commonly in patients receiving hemodialysis, with infective endocarditis being a relatively uncommon, but potentially lethal complication. Valvular calcification is the most significant risk factor. The diagnosis of infective endocarditis is made clinically and confirmed with the echocardiographic modified Duke's criteria. The most common pathogen is Staphylococcus aureus and the mitral valve is the most common site. Staphylococcus aureus infective endocarditis is commonly associated with embolic phenomenon. A high index of suspicion is critical in the early recognition and management of infective endocarditis. However, prevention of bacteremia is undoubtedly the best strategy with the early placement of arteriovenous fistulae. In the case of temporary catheterization, the use of topical mupirocin or polysporin and gentamicin and/or citrate locking is beneficial. Although catheter salvage has not been studied in randomized trials, catheter removal remains standard therapy during bacteremia.

    Background: Given the lack of clear indications for the use of warfarin in the treatment of atrial fibrillation (AF) in patients on hemodialysis and the potential risks that accompany warfarin use in these patients, we systematically reviewed stroke and bleeding outcomes in hemodialysis patients treated with warfarin for AF. Objective: To systematically review the stroke and bleeding outcomes associated with warfarin use in the hemodialysis population to treat AF. Design: Systematic review. Setting: All adult hemodialysis patients. Patients: Patients on hemodialysis receiving warfarin for the management of AF. Measurements: Any type of stroke and/or bleeding outcomes. Methods: MEDLINE(R) In-Process & Other Non-Indexed Citations and MEDLINE(R) via OVID (1946 to January 11, 2017), and EMBASE via OVID (1974 to January 11, 2017) were searched for relevant literature. Inclusion criteria were randomized controlled trials, observational studies, and case series in English that examined stroke and bleeding outcomes in adult population of patients (over 18 years old) who are on hemodialysis and taking warfarin for AF. Studies with less than 10 subjects, case reports, review articles, and editorials were excluded. Quality of selected articles was assessed using Newcastle-Ottawa Scale (NOS). Results: Of the 2340 titles and abstracts screened, 7 met the inclusion criteria. Two studies showed an association between warfarin use and an increased risk of stroke (Hazard Ratio: 1.93-3.36) but no association with an increased risk of bleed (HR: 0.85-1.04), while 4 studies showed no association between warfarin and stroke outcomes (HR: 0.12-1.17) but identified an association between warfarin and increased bleeding outcome (HR: 1.41-3.96). And 1 study reported neither beneficial nor harmful effects associated with warfarin use. Limitations: The major limitation to this review is that the 7 included studies were observational cohort studies, and thus the outcome measures were not

  17. Elevated serum aluminum levels in hemodialysis patients associated with use of electric pumps--Wyoming, 2007.

    2008-06-27

    Aluminum toxicity can cause osteomalacia, anemia, and dementia in hemodialysis patients and has historically been associated with exposure to contaminated water or dialysate preparations or ingestion of aluminum-containing phosphate binders. Since 2002, improvements in water treatment methods and use of non-aluminum-containing phosphate binders have resulted in low prevalence (<1%) of aluminum toxicity among hemodialysis patients. In the United States, reported cases of aluminum toxicosis are rare, and no outbreak has been reported since 1992. This report describes 10 patients treated at a hemodialysis unit in a Wyoming hospital (hospital A) in 2007 who had elevated serum aluminum levels that were detected through routine serum aluminum screening. An investigation was conducted by the Wyoming Department of Health, which determined that the source of exposure was dialysate acid concentrate that became contaminated with aluminum as it passed through two electric drum pumps. The drum pumps had been used to transfer dialysate acid concentrate from 55-gallon storage drums to 1-gallon jugs for use on individual hemodialysis machines. Removal of the pumps from service resulted in a rapid reduction in patient serum aluminum levels. The findings suggest that regular assessment of machine compatibility with dialysate fluid is needed.

    OBJECTIVES: to assess renal function in elderly patients undergoing contrast-enhanced computed tomography and identify the preventive measures of acute kidney injury in the period before and after the examination. METHOD: longitudinal cohort study conducted at the Federal University of São Paulo Hospital, from March 2011 to March 2013. All hospitalized elderly, of both sexes, aged 60 years and above, who performed the examination, were included (n=93). We collected sociodemographic data, data related to the examination and to the care provided, and creatinine values prior and post exam. RESULTS: an alteration in renal function was observed in 51 patients (54%) with a statistically significant increase of creatinine values (p<0.04), and two patients (4.0%) required hemodialysis. CONCLUSION: There is an urgent need for protocols prior to and post contrast-enhanced examination in the elderly, and other studies to verify the prognosis of this population. PMID:25296148

    Malnutrition, inflammation, and renal osteodystrophy parameters with resultant coronary calcification (CC) are associated with increased cardiovascular mortality in adults. Previous pediatric studies demonstrated CC in children but none assessed for an association between inflammation, malnutrition, renal osteodystrophy, and CC. To assess CC, ultrafast computerized tomogram was obtained for 16 pediatric patients (6 females; median age 17.2 years; range 9.1-21.2 years) receiving hemodialysis for >/=2 months. Inflammation was assessed by serum IL-6, IL-8, and C-reactive protein levels on the day of the computerized tomogram scan; nutrition parameters included serum albumin, cholesterol, the body mass index standard deviation score, and normalized protein catabolic rate. Renal osteodystrophy parameters included time-averaged serum calcium, phosphorus, total PTH, and calcitriol/calcium dose. Patients received hemodialysis thrice-weekly; mean single pool Kt/V 1.48+/-0.13; and mean normalized protein catabolic rate 1.27+/-0.17 g/kg/day. Five of 16 patients had CC. Patients with CC were older (19.1+/-2.1 vs. 15.4+/-3.1 months; P=0.03), had longer dialysis vintage (49.4+/-15.3 vs. 17.2+/-10.5 months, P=0.0002), lower serum cholesterol (122+/-17.7 vs. 160.4+/-10.6 mg/dL, P=0.02), and higher phosphorus (9.05+/-1.2 vs. 6.1+/-0.96 mg/dL, P=0.0001). Mean serum albumin and normalized protein catabolic rate did not differ for patients with CC. All patients had elevated IL-6 and IL-8 levels compared with healthy norms; the mean IL-6, IL-8, and C-reactive protein levels were not different in patients with CC. Coronary calcification was prevalent in older children receiving maintenance hemodialysis with a longer dialysis vintage. Worse renal osteodystrophy control and malnutrition (low cholesterol) may contribute to CC development.

    Iodine-131 ablation therapy for thyroid cancer in the patient on chronic hemodialysis represents a real problem since the main route of elimination of radioiodine is urinary. There is no recommendation on the management of this treatment in the patient on hemodialysis. We report our experience of management of this treatment in a patient aged 38 years, undergoing hemodialysis for chronic renal failure, and who have been indicated the treatment with iodine-131 for papillary thyroid carcinoma high risk. After multidisciplinary discussions (nephrologists and specialists in nuclear medicine and radiation safety), it has been decided to treat the patient with continuous ambulatory peritoneal dialysis therapy (CAPD). Because of the low but continuous elimination of iodine in the case of CAPD, the patient received a reduced ablative (131)I dose of 1850 MBq, which is 30% of the usual dose delivered in subjects with normal renal function. The patient was hospitalized for four days in nuclear medicine unit and the (131)I radioactivity emitted from him was 2.5 μSv/h at one meter at his hospital discharge. In conclusion, CAPD in relay of hemodialysis is a technique of renal replacement therapy that can be suggested to minimize exposure to radioactivity to the patient, his family and the medical staff.

    Summary Background and objectives Geographic and other variations in medical practices lead to differences in medical costs, often without a clear link to health outcomes. This work examined variation in the frequency of physician visits to patients receiving hemodialysis to measure the relative importance of provider practice patterns (including those patterns linked to geographic region) and patient health in determining visit frequency. Design, setting, participants, & measurements This work analyzed a nationally representative 2006 database of patients receiving hemodialysis in the United States. A variation decomposition analysis of the relative importance of facility, geographic region, and patient characteristics—including demographics, socioeconomic status, and indicators of health status—in explaining physician visit frequency variation was conducted. Finally, the associations between facility, geographic and patient characteristics, and provider visit frequency were measured using multivariable regression. Results Patient characteristics accounted for only 0.9% of the total visit frequency variation. Accounting for case-mix differences, patients’ hemodialysis facilities explained about 24.9% of visit frequency variation, of which 9.3% was explained by geographic region. Visit frequency was more closely associated with many facility and geographic characteristics than indicators of health status. More recent dialysis initiation and recent hospitalization were associated with decreased visit frequency. Conclusions In hemodialysis, provider visit frequency depends more on geography and facility location and characteristics than patients’ health status or acuity of illness. The magnitude of variation unrelated to patient health suggests that provider visit frequency practices do not reflect optimal management of patients on dialysis. PMID:23430207

    Vascular access infections are of concern to hemodialysis patients and nurses. Best demonstrated practices (BDPs) have not been developed for home hemodialysis (HHD) access use, but there have been generally accepted practices (GAPs) endorsed by dialysis professionals. We developed a survey to gather information about training provided and actual practices of HHD patients using the NxStage System One HHD machine. We used GAP to assess training used by nurses to teach HHD access care and then assess actual practice (adherence) by HHD patients. We also assessed training and adherence where GAPs do not exist. We received a 43% response rate from patients and 76% response from nurses representing 19 randomly selected HHD training centers. We found that nurses were not uniformly instructing HHD patients according to GAP, patients were not performing access cannulation according to GAP, nor were they adherent to their training procedures. Identification of signs and symptoms of infection was commonly trained appropriately, but we observed a reluctance to report some signs and symptoms of infection by patients. Of particular concern, when aggregating all steps surveyed, not a single nurse or patient reported training or performing all steps in accordance with GAP. We also identified practices for which there are no GAPs that require further study and may or may not impact outcomes such as infection. Further research is needed to develop strategies to implement and expand GAP, measure outcomes, and ultimately develop BDP for HHD to improve infectious complications. © 2014 The Authors.

    Objective: To explore the level of resting energy expenditure (REE) estimated by bioelectrical impedance analysis and the association of resting metabolic rate (RMR) with clinical related factors, and provide new ideas for improving protein energy wasting (PEW) in maintenance hemodialysis (MHD) patients. Methods: Seven hundred and sixty-five subjects receiving MHD between July 2015 and September 2016 in 11 hemodialysis centers in Guizhou province were enrolled in this cross-sectional study. Bioelectrical impedance analysis was used to measure RMR and body composition, such as lean body mass, fat mass and body cell mass (BCM). Baseline characteristics, routine blood test indexes and biochemical data of hemodialysis patients were collected. The level of RMR and body composition in hemodialysis patients was compared by gender grouping. Then the patients were divided into four groups according to the cutoff value of RMR quartile. Spearman correlation analysis and multiple linear regression analysis were used to analyze the relationships between RMR and clinical related factors. Results: The average age of MHD patients was (54.96±15.78) years and the duriation of dialysis was (42.3±9.0) months. The level of RMR in male patients (474 cases, 61.96%) was significantly higher than that in female patients [1 591(1 444, 1 764) kcal/d vs 1 226 (1 104, 1 354) kcal/d, P <0.001]. However, this significant difference of RMR between different genders disappeared after adjusting for lean body mass ( P =0.193). Multiple linear regression analysis showed that RMR was positively correlated with body surface area (β=0.817) and lactate dehydrogenase (LDH) (β=0.198), and negatively correlated with age (β=-0.141), all P <0.05. Conclusion: RMR levels in patients with maintenance hemodialysis are associated with lactate dehydrogenase level, which may become a new index to evaluate energy consumption.

    Prior small studies have shown multiple benefits of frequent nocturnal hemodialysis compared to conventional three times per week treatments. To study this further, we randomized 87 patients to three times per week conventional hemodialysis or to nocturnal hemodialysis six times per week, all with single-use high-flux dialyzers. The 45 patients in the frequent nocturnal arm had a 1.82-fold higher mean weekly stdKt/Vurea, a 1.74-fold higher average number of treatments per week, and a 2.45-fold higher average weekly treatment time than the 42 patients in the conventional arm. We did not find a significant effect of nocturnal hemodialysis for either of the two coprimary outcomes (death or left ventricular mass (measured by MRI) with a hazard ratio of 0.68, or of death or RAND Physical Health Composite with a hazard ratio of 0.91). Possible explanations for the left ventricular mass result include limited sample size and patient characteristics. Secondary outcomes included cognitive performance, self-reported depression, laboratory markers of nutrition, mineral metabolism and anemia, blood pressure and rates of hospitalization, and vascular access interventions. Patients in the nocturnal arm had improved control of hyperphosphatemia and hypertension, but no significant benefit among the other main secondary outcomes. There was a trend for increased vascular access events in the nocturnal arm. Thus, we were unable to demonstrate a definitive benefit of more frequent nocturnal hemodialysis for either coprimary outcome. PMID:21775973

    The mortality of the population with chronic kidney disease (CKD) on hemodialysis (HD) is very high and the protein-energy malnutrition stands out as one of the most common consequences in relation to this condition. To evaluate the association between time of hemodialysis and nutritional parameters of patients. It is a cross-sectional study with secondary data, developed of the University Hospital of the Federal University of Juiz de Fora (HU/UFJF). This study was approved by the Research Ethics Committee (Nº 1.233.142), a total of 36 patients. The medical records and collected data were analyzed for anthropometric markers, biochemical and diet, considering two groups: HD time less than three and greater than or equal to three years. There was reduction of mass of somatic protein with increased duration of HD. In relation to food intake was observed that in patients with increased duration of dialysis, an increase in average consumption of protein / kg of weight, calories, phosphorus and potassium, with a significant difference from the mean protein intake / kg (p = 0.04) and phosphorus (p = 0.045). Increasing HD time has altered body composition of patients, indicating a decline in the nutritional status of these individuals. HD patients are a risk group for protein-energy malnutrition, where HD time interferes with the nutritional status and food profile of the patient. The group HD time greater than or equal to 3 years presented worsening nutritional status.

    Health-related quality of life (HRQOL) is an index to calculate wellbeing of patients and is an important concept in patients with end-stage renal disease.  There are many studies calculating HRQOL for patients on different treatment modalities of end-stage renal disease. Pooling reports from Iran, this systematic review aimed to measure the HRQOL in patients on hemodialysis and peritoneal dialysis using meta-analysis techniques. Four databases including PubMed and Scopus in English and the SID and IranMedex in Persian were searched. Based on the inclusion criteria, 26 English and Persian-language articles reporting HRQOL in the scales between zero and 100 (or scales convertible to this range) for hemodialysis or PD were included in the meta-analysis. The mean HRQOL scores ranged between 34.40 and 69.16 for hemodialysis reports and between 38.00 and 65.70 for PD reports. The pooled quality of life scores for hemodialysis and PD were 52.257 and 52.722, respectively (t = 0.928, P = .36). The results showed that HRQOL in patients using hemodialysis and peritoneal dialysis were not significantly different. Similar studies in other countries had found similar results.

    Depressive and anxious patients on hemodialysis have a higher risk of death and hospitalizations. The aim of this study was to evaluate the effect of nurse-led telephone follow ups (tele-nursing) on depression, anxiety and stress in hemodialysis patients. The subjects of the study who were selected based on double blind randomized clinical trial consisted of 60 patients with advanced chronic renal disease treated with hemodialysis. The patients were placed in two groups of 30 individuals. Before the intervention, a questionnaire was completed by patients.  There was no telephone follow up in the control group and the patients received only routine care in the hospital. The participants allocated to the intervention group received telephone follow-up 30 days after dialysis shift, in addition to conventional treatment. Every session lasted 30 minutes, as possible. Then the DASS scale was filled out by the patients after completion of study by two groups. Significant differences were observed between the two groups in the posttest regarding the dimensions scores of DASS scale. The result of this trial is expected to provide new knowledge to support the effective follow-up for hemodialysis patient in order to improve their emotional and health status.

    Lanthanum carbonate, a chewable noncalcium-containing phosphorus (P) binder, is useful for treating secondary hyperparathyroidism in patients who have hypercalcemia and cannot swallow whole tablets. However, some patients cannot chew tablets or prefer to crush and mix them with food. This study was conducted to determine the P-binding efficacy of crushed lanthanum and compare it with chewed lanthanum in hemodialysis (HD) patients. After a 1-week washout period, 11 hemodialysis patients (7 men, 4 women) were randomized to receive, in a crossover fashion, lanthanum 1000 mg 3 times daily chewed with meals and lanthanum 1000 mg 3 times daily crushed into a fine powder, mixed with applesauce and taken with meals, for 4 weeks each. Serum P was measured at the end of each washout (baseline) and weekly during treatment. Changes in serum P from baseline for crushed lanthanum were compared with chewed lanthanum using paired sample t test. Administration of crushed lanthanum resulted in a significant reduction in serum P from baseline (P reduction [mg/dL] for crushed lanthanum in week 1: 2.1 ± 0.4, week 2: 1.7 ± 0.5, week 3: 1.7 ± 0.5, week 4: 1.7 ± 0.4, P<0.05). No statistically significant differences were observed in serum P reduction from baseline and serum P attained during treatment with crushed when compared with chewed lanthanum. Crushed lanthanum is effective in reducing serum P and have similar P-binding efficacy to chewed lanthanum. Crushing lanthanum and mixing it with food can thus be an option for patients who are unable to chew or swallow whole tablets. © 2010 The Authors.

    Insulin resistance and vascular remodeling are prevalent and predict cardiovascular mortality in hemodialysis patients. Angiotensin II (Ang II) may be involved in both pathogenesis. In the present study, we investigated the effects of the Ang II receptor blocker losartan on insulin resistance, arterial stiffness, and carotid artery structure in hemodialysis patients. Seventy-two hemodialysis patients were randomly assigned to receive either losartan 50 mg qd (n = 36) or β-blocker bisoprolol 5 mg qd (n = 36). At the start and at month 12, ambulatory blood pressure (BP) monitoring, aortic pulse wave velocity (PWV) measurements, and carotid artery ultrasound were performed, and homeostasis model assessment index of insulin resistance (HOMA-IR) was determined. During the study period, bioimpedance method was used to evaluate volume status every 3 months. Home-monitored BPs were measured at least monthly. Ambulatory BP decreased significantly and similarly by either losartan or bisoprolol. Decreases in PWVs in losartan group at the end of month 12 were significantly greater than changes in PWV in bisoprolol group (0.9 ± 0.3 vs. 0.4 ± 0.5 m/s, P = 0.021). Common carotid artery intima-media cross-sectional area decreased significantly only in patients treated with losartan (20.3 ± 4.9 vs. 19.1 ± 5.1 mm(2) , P = 0.001), and HOMA-IR was also reduced in losartan group only (1.9 ± 1.0 vs. 1.7 ± 0.8, P = 0.003). Multiple regression analysis showed significant correlations between changes in PWV and changes in HOMA-IR. With comparable BP-lowering efficacy, losartan achieved better improvement in insulin sensitivity, arterial stiffness, and carotid artery hypertrophy in hemodialysis patients. The regression of arterial stiffness may be in part through attenuation in insulin resistance. © 2015 International Society for Hemodialysis.

    Background and objectives Recent studies demonstrated an association between depressive affect and higher mortality risk in incident hemodialysis patients. This study sought to determine whether an association also exists with hospitalization risk. Design, setting, participants, & measurements All 8776 adult incident hemodialysis patients with Medical Outcomes Study Short Form 36 survey results treated in Fresenius Medical Care North America facilities in 2006 were followed for 1 year from the date of survey, and all hospitalization events lasting >24 hours were tracked. A depressive affect score was derived from responses to two Medical Outcomes Study Short Form 36 questions (“down in the dumps” and “downhearted and blue”). A high depressive affect score corresponded with an average response of “some of the time” or more frequent occurrence. Cox and Poisson models were constructed to determine associations of depressive affect scores with risk for time to first hospitalization and risk for hospitalization events, as well as total days spent in the hospital, respectively. Results Incident patients with high depressive affect score made up 41% of the cohort and had a median (interquartile range) hospitalization event rate of one (0, 3) and 4 (0, 15) total hospital days; the values for patients with low depressive affect scores were one (0, 2) event and 2 (0, 11) days, respectively. For high-scoring patients, the adjusted hazard ratio for first hospitalization was 1.12 (1.04, 1.20). When multiple hospital events were considered, the adjusted risk ratio was 1.13 (1.02, 1.25) and the corresponding risk ratio for total hospital days was 1.20 (1.07, 1.35). High depressive affect score was generally associated with lower physical and mental component scores, but these covariates were adjusted for in the models. Conclusions Depressive affect in incident hemodialysis patients was associated with higher risk of hospitalization and more hospital days. Future

    Malnutrition with hypoalbuminemia is an independent predictor of mortality in end-stage renal disease patients. Anabolic steroids reduce protein catabolism and therefore may improve nutritional parameters. This study was undertaken to determine the effects of the anabolic steroid nandrolone decanoate on the nutritional status of hemodialysis patients. Secondary endpoints were to examine the effects of androgen therapy on hematocrit and erythropoietin (EPO) dose. Medical records of chronic hemodialysis patients who received nandrolone decanoate for greater than 30 days were reviewed. Data collected included: demographics, dose, frequency, duration of treatment and cumulative dose of nandrolone. Baseline albumin, transferrin, dry weight, phosphorus, creatinine, hematocrit and erythropoietin dose were obtained for comparison with values after treatment. Of the 9 patients evaluated (mean +/- SD: age 55+/-28 years, 4/9 male), 2 patients received nandrolone doses of 25 mg intramuscularly (i.m.) every week, while the remaining 7 patients received 100 mg i.m. every 2 weeks. The mean +/- SD duration of treatment was 96+/-43 days, with a mean +/- SD cumulative dose of 656+/-371 mg. The mean +/- SD baseline albumin was 2.9+/-0.6 mg/dl which increased to 3.3+/-0.4 mg/dl after treatment (p = 0.045). Dry weight increased from a mean +/- SD of 64.4+/-11.7 kg to 66.0+/-10.9 kg after nandrolone therapy (p = 0.028). Mean +/- SD hematocrit at baseline was 28.2+/-4.5% and increased to 33.2+/-5.1% (p = 0.033). The dose of EPO was reduced in 4 patients (44%) during nandrolone therapy. Nandrolone significantly improved markers of nutritional status in our hemodialysis patients. This therapy may also enhance the hematopoietic effects of EPO.

    We report the case of a 44-year-old female undergoing maintenance hemodialysis in whom early-phase rheumatoid arthritis (RA) was successfully treated by leukocytapheresis (LCAP). The effects of prednisone, tacrolimus, and etanercept were limited, but LCAP was highly effective and its efficacy continued even after cessation of LCAP. Moreover, remission was maintained for 2 years after discontinuation of medication. LCAP may be an important treatment option for RA patients with end-stage renal failure who are on hemodialysis.

    The aim of this study is to examine the effectiveness of foot reflexology and back massage on optimizing the sleep quality and reducing the fatigue of hemodialysis patients. The study includes 105 volunteer patients who were registered at a private dialysis clinic and were receiving hemodialysis treatment. Foot reflexology and back massage were administered to the patients two times a week for four weeks. The Visual Analogue Scale for Fatigue and the Pittsburg Sleep Quality Index were used to collect data. The differences between the pretest and posttest score averages of the patients on the Visual Analogue Scale for Fatigue and the Pittsburg Sleep Quality Index were statistically significant (p < 0.001). Foot reflexology and back massage were shown to improve the sleep quality and reduce the fatigue of hemodialysis patients. Compared to back massage, foot reflexology was determined to be more effective. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Health-related quality of life (HRQOL) is an important outcome in dialysis care. Previous research has related protein-energy nutritional status to generic HRQOL domains, but it is still not clear as to how it relates to HRQOL domains that are unique to hemodialysis patients. Therefore, our aim was to study the relation between protein-energy nutritional status and kidney disease-specific HRQOL domains in hemodialysis patients. This was a cross-sectional study. This study was performed at multiple centers. We evaluated the first 590 hemodialysis patients who had enrolled in the Convective Transport Study. We measured protein-energy nutritional status by using the Subjective Global Assessment, albumin, normalized nitrogen appearance, creatinine, body mass index, and cholesterol. HRQOL was assessed by using the Kidney Disease Quality Of Life-Short Form. In all, 83% of the cohort was found to be well-nourished on the basis of the Subjective Global Assessment. Multiple nutritional parameters were positively related to the physical summary of generic HRQOL and to the following kidney disease-specific HRQOL scales: the effects of the kidney disease on daily life, the burden of the kidney disease, and overall health. This study showed that, even in predominantly well-nourished hemodialysis patients, protein-energy nutritional status was significantly related to kidney disease-specific HRQOL.

    Gastrointestinal (GI) symptoms are common in patients with chronic renal failure (CRF). We have previously demonstrated that patients with predialysis end-stage renal disease showed a high prevalence of GI symptoms and gastric hypomotility, and that gastric hypomotility appears to be an important factor in generating GI symptoms. However, it is not clear whether impaired gastric motor function would improve after hemodialytic treatment. To examine the relationship between gastric motor function and GI symptoms in CRF patients on hemodialysis. The study was performed in 19 patients with CRF treated with hemodialysis for more than six months and in 12 matched healthy controls. GI symptom severity was quantified in all patients. Gastric motility was evaluated with cutaneously recorded electrogastrography (EGG) and gastric emptying of semi-solid meals using the (13)C-acetic acid breath test. Six patients had no symptoms, and 11 had slight GI symptoms with a total symptom score of less than 5. Compared with controls, CRF patients revealed no differences in gastric motility parameters, with the exception of a lower percentage of normogastria in EGG at fasting state. Eleven patients had normal gastric motor function (Group A), and eight showed abnormalities of either gastric myoelectrical activity or gastric emptying (Group B). There was no difference in symptom score between Group A and Group B. More than half of the patients with CRF on hemodialysis demonstrated normal gastric motility, and no or slight GI symptoms. Hemodialytic treatment may improve impaired gastric motility and reduce GI symptoms in patients with CRF.

    Radioiodine therapy could be challenging in chronic renal failure patients requiring hemodialysis. The aim of this study was to establish the effects of hemodialysis on elimination of radioiodine from the body in thyroid carcinoma patients with end-stage chronic renal failure and to determine its effects on environmental radiation dose. Three end-stage chronic renal failure patients (four cases) diagnosed with differentiated thyroid carcinoma requiring radioiodine therapy were included in our study. Each patient was given 50-75 mCi (1850-2775 MBq) iodine-131 with 50% dose reduction. Dose rate measurement was performed at the 2nd, 24th, and 48th hour (immediately before and after hemodialysis) after radioiodine administration. The Geiger-Müller probe was held at 1 m distance at the level of the midpoint of the thorax for the dose rate measurement. The effective half-life of iodine-131 for three patients was found to be 44 h. In conclusion, the amount of radioiodine excreted per hemodialysis session was calculated to be 51.25%.

    Patients undergoing maintenance hemodialysis develop both structural and functional cardiovascular abnormalities. Despite improvement of dialysis technology, cardiovascular mortality of this population remains high. The pathophysiological mechanisms of these changes are complex and not well understood. It has been postulated that several non-traditional, uremic-related risk factors, especially the long-term uremic state, which may affect the cardiovascular system. There are many cardiovascular changes that occur in chronic kidney disease including left ventricular hypertrophy, myocardial fibrosis, microvascular disease, accelerated atherosclerosis and arteriosclerosis. These structural and functional changes in patients receiving chronic dialysis make them more susceptible to myocardial ischemia. Hemodialysis itself may adversely affect the cardiovascular system due to non-physiologic fluid removal, leading to hemodynamic instability and initiation of systemic inflammation. In the past decade there has been growing awareness that pathophysiological mechanisms cause cardiovascular dysfunction in patients on chronic dialysis, and there are now pharmacological and non-pharmacological therapies that may improve the poor quality of life and high mortality rate that these patients experience.

    Chronic hepatitis B and C are important causes of liver disease in hemodialysis units. The most important route of transmission is the inapparent parenteral route; known risk factors are the high prevalence of HBV and HCV infections in hemodialysis units, previous blood transfusions, long-term dialysis treatment, frequent changes of hemodialysis unit, and previous renal transplants. The source, time and duration of infection are often difficult to ascertain. The studies investigating the natural history of viral hepatitis in hemodialysis patients are few and limited by a short follow-up, but they show an independent and negative impact on survival due to an increased risk of liver cirrhosis and hepatocellular carcinoma. The treatment options include conventional or pegylated interferon (alone or in association with ribavirin) and the nucleoside/nucleotide analogs. The aim of treatment is viral eradication or persistent suppression of viral replication. The altered pharmacokinetics, the increased risk of drug-related toxicity, and the need for renal transplant complicate the management of antiviral therapy. In patients with chronic HBV infection and active replication the most common approach is persistent suppression of viral replication using nucleoside/nucleotide analogs. As regards hepatitis C, several clinical trials evaluating conventional interferon monotherapy have shown higher sustained virological response and dropout rates in dialysis patients than in patients with normal kidney function. Data about pegylated interferon as monotherapy or in association with ribavirin are promising but limited. Hemodialyzed patients obtaining a sustained virological response often maintain the response after kidney transplantation.

    Data generated with the body composition monitor (BCM, Fresenius) show, based on bioimpedance technology, that chronic fluid overload in hemodialysis patients is associated with poor survival. However, removing excess fluid by lowering dry weight can be accompanied by intradialytic and postdialytic complications. Here, we aim at testing the hypothesis that, in comparison to conventional hemodialysis, blood volume-monitored regulation of ultrafiltration and dialysate conductivity (UCR) and/or regulation of ultrafiltration and temperature (UTR) will decrease complications when ultrafiltration volumes are systematically increased in fluid-overloaded hemodialysis patients. BCM measurements yield results on fluid overload (in liters), relative to extracellular water (ECW). In this prospective, multicenter, triple-arm, parallel-group, crossover, randomized, controlled clinical trial, we use BCM measurements, routinely introduced in our three maintenance hemodialysis centers shortly prior to the start of the study, to recruit sixty hemodialysis patients with fluid overload (defined as ≥15% ECW). Patients are randomized 1:1:1 into UCR, UTR and conventional hemodialysis groups. BCM-determined, 'final' dry weight is set to normohydration weight -7% of ECW postdialysis, and reached by reducing the previous dry weight, in steps of 0.1 kg per 10 kg body weight, during 12 hemodialysis sessions (one study phase). In case of intradialytic complications, dry weight reduction is decreased, according to a prespecified algorithm. A comparison of intra- and post-dialytic complications among study groups constitutes the primary endpoint. In addition, we will assess relative weight reduction, changes in residual renal function, quality of life measures, and predialysis levels of various laboratory parameters including C-reactive protein, troponin T, and N-terminal pro-B-type natriuretic peptide, before and after the first study phase (secondary outcome parameters).

    The present study was conducted to investigate the effect of individual, multistep intervention on adherence to treatment in hemodialysis patients referred to a hemodialysis center in Shahrekord, Iran. In this interventional study, hemodialysis patients referring the center of the study were randomly assigned into two control and intervention groups (each 33). The control group received routine treatment, recommended dietary and fluid restrictions. The intervention group participated in eight individual interventional sessions accompanied routine treatment. At the beginning and the end of the study, routine laboratory tests and end-stage renal disease-adherence questionnaire were filled out for patients in both groups. The data were analyzed using Mann-Whitney and Wilcoxon tests. At the end of the study, the two groups showed a significant difference in all domains of adherence except adherence to diet and adherence was better in the intervention group (p < 0.05). In demographic characteristic, only age indicated a positive correlation with adherence to dialysis program (p = 0.04, r = 0.254). After intervention, serum phosphorus decreased significantly in the intervention group (p < 0.05). Adherence to treatment is one of the major problems in hemodialysis patients; however, comprehensive interventions are required in view of individual condition. Implications for Rehabilitation Adherence to treatment means that all patients' behaviors (diet, fluids and drugs intake) should be in line with the recommendations given by healthcare professionals. There is evidence on the association between adherence to treatment and decreased risk of hospitalization in dialysis patients. Individual structured programs are most likely to be successful in encouraging adherence to treatment.

    The optimal management of stroke prophylaxis in hemodialysis patients with atrial fibrillation is controversial. The purpose of this study was to determine the risk of mortality, stroke, and bleeding associated with the use of warfarin in hemodialysis patients with atrial fibrillation. This was a retrospective, population-based study of hemodialysis patients with atrial fibrillation between January 1, 2006, and September 30, 2015. Association of warfarin use with mortality, stroke, and bleeding was determined by propensity score-matched, Cox proportional hazard models. Among the 4286 patients with atrial fibrillation on hemodialysis, 989 (23%) were prescribed warfarin. Propensity score matching was used to identify 888 matched pairs with similar baseline characteristics. Warfarin use was associated with lower risk of all-cause death (hazard ratio [HR] 0.76, 95% confidence interval [CI] 0.69-0.84) and lower risk of ischemic stroke (HR 0.68, 95% CI 0.52-0.91). Warfarin use was not associated with a higher risk of hemorrhagic stroke (HR 1.2, 95% CI 0.6-2.2) or gastrointestinal bleeding (HR 0.97, 95% CI 0.77-1.2). The treatment effect was largest in the group with the best international normalized ratio control as measured by time in therapeutic range. Subgroup analyses showed warfarin use was associated with survival benefit in most subgroups. The 2 subgroups that did not benefit were patients with a history of hemorrhagic stroke and patients with concurrent aspirin use. Warfarin use is associated with lower all-cause mortality and ischemic stroke, without significantly increasing the risk of bleeding in hemodialysis patients with atrial fibrillation.

    The regulation of mineral homeostasis is altered in hemodialysis patients with renal insufficiency, producing increased risk for secondary diseases like cardiovascular ones. We hypothesized that risen serum aluminum (Al) concentration in hemodialysis patients kept enhanced during a 2-year longitudinal study is associated with enhanced cardiovascular risk and influenced by medical treatments. This study reports the prospective monitoring of serum Al levels in six-monthly samplings over 2 years in 116 hemodialysis patients and a control group of 50 healthy adults. The influence of other factors like sex, age, kidney transplant, disease etiology, and drug consumption was also considered. At each sampling, serum Al levels were significantly higher in the patients than in the healthy controls (P < 0.05). Levels in the patient group were statistically significantly lower at the third and fourth versus first and second samplings, which may be related to Al accumulation in tissues. Increased Al levels in patients were positively and significantly related to serum calcium (Ca) and uric acid levels. Serum Al concentrations were significantly lower in patients receiving vasodilators and diuretics. Higher serum Al levels in hemodialyzed patients administered with phosphate binders or anti-hyperkalemics are attributable to their usual Al salt content. The consumption of antianemic drugs increases Al absorption by forming more bioavailable complexes with the compounds in these drugs. In conclusion, this is the first study to indicate that cardiovascular problems associated with elevated serum Al levels in hemodialysis patients may be in part mitigated by administrating vasodilators and diuretics, which reduce these levels.

    Hepatitis C virus (HCV) infection is a common cause of acute and chronic hepatitis among the hemodialysis population. To prevent cross infection between hemodialysis patients during the hemodialysis procedure, routine screening of anti-HCV antibody is recommended. However, a reactive anti-HCV EIA test is not equal to active HCV infection. An expensive RT-PCR study is required to confirm HCV viremia. This will significantly increase the cost burden because payment for each hemodialysis treatment is very low in Taiwan. Thus, it is useful to identify parameters that could predict HCV viremia among anti-HCV-reactive patients. In this study, we examined the usefulness of signal-to-cut (S/CO) ratio of anti-HCV antibody in discriminating HCV viremia from non-viremia among the anti-HCV-reactive hemodialysis population. In a cross-sectional measurement of anti-HCV antibody among 369 chronic hemodialysis patients, 44 showed reactive and 9 grey zone reaction for anti-HCV. These 53 patients underwent further blood tests for the measurement of AST, ALT and HCV RNA (by RT-PCR). The results of RT-PCR were used as a dependent variable. Then, S/CO ratios of anti-HCV, serum AST, ALT levels, age and duration of hemodialysis were used as independent variables to undergo ROC curve and logistic regression analysis. Thirty-six of the 53 reactive and grey zone patients were positive for HCV RNA in the RT-PCR study. Patients who were positive for HCV RNA had a higher S/CO ratio (p < 0.01), higher AST and ALT levels (p < 0.01), and longer duration on hemodialysis (p < 0.05) than those negative for HCV RNA. Logistic regression revealed that only S/CO ratio was a significant predictor for HCV viremia (p = 0.004). ROC curve analysis showed that S/CO ratio had a highest area under curve (0.967, p < 0.001), followed by ALT (0.826, p < 0.001), AST (0.778, p = 0.001), duration on hemodialysis (0.606, p = 0.215) and age (0.426, p = 0.386) in discriminating HCV viremia from non-viremia.

    The fatigue that is observed in patients who are undergoing dialysis is usually associated with an impaired quality of life. The present cross-sectional study was conducted from January to April 2009 in three hemodialysis units in Kuala Lumpur, Malaysia. In this study, the Multidimensional Fatigue Inventory and Depression Anxiety and Stress Score 21 were used to determine the level of fatigue, depression, anxiety, and stress of patients who were undergoing dialysis. The data were obtained from a calculated sample of 116 and a total of 103 respondents participated in the study. A total of 56 (54.4%) and 47 (45.6%) respondents experienced a high level and a low level of fatigue, respectively. There was a significant relationship between the duration of treatment and the level of fatigue. The respondents who had been receiving treatment for > 2 years experienced more fatigue, compared to the respondents who had been undergoing hemodialysis for > 2 years. There was a significant difference in relation to the age of the participants regarding the level of fatigue. No significant relationship between the sex of the participants, anemia, depression, anxiety, stress, and the level of fatigue was observed. Special attention needs to be paid to both the younger and older adults who are receiving treatment. In addition, proper planning is needed for the patients regarding their daily activities in order to reduce fatigue. Nurses who work in hemodialysis units are recommended to provide exercise classes or group therapy in order to boost the energy levels among patients who are undergoing dialysis. Health professionals should provide appropriate treatment for patients who are experiencing fatigue in order to prevent any other complications that could arise. © 2011 Blackwell Publishing Asia Pty Ltd.

    Cardiovascular disease is the leading cause of morbidity and mortality in patients undergoing hemodialysis. Such patients frequently develop complications such as asymptomatic coronary artery disease (CAD). Accordingly, CAD must ideally be diagnosed at an early stage to improve prognosis. Although myocardial perfusion single photon emission computed tomography (SPECT) is valuable for diagnosing CAD, the stress test is not always applicable to patients on hemodialysis. Thus, we proposed a multicenter, prospective cohort study called "B-SAFE" to investigate the applicability of resting (123)I-labeled beta-methyl-iodophenylpentadecanoic acid ((123)I-BMIPP)-SPECT will be used to diagnose cardiac disease and evaluate the prognosis of hemodialysis patients by imaging myocardial fatty acid metabolism. B-SAFE began enrolling patients from June 2006 at 48 facilities. We performed (123)I-BMIPP-SPECT on 702 hemodialysis patients with risk factors for CAD until 30 November 2007 and plan to follow up for three years. The primary endpoints will be cardiac death and sudden death. This study should end in 2010.

    Patients with chronic renal failure (CRF) were on maintenance invasive haemodialysis (HD) procedure. This procedure by itself affects immunity of the patients and they become more susceptible to viral infections. We investigate the occurrence of HBV HCV and HIV infections in patients with hemodialysis. A retrospective study of 430 endstage renal failure patients referred to hemodialysis department at AlKindy Teaching Hospital Baghdad, Iraq from January 2015 to January 2017 was conducted. Patients were investigated for HBsAg using enzymelabeled antigen test (ForesightEIAUSA) HCV Abs (IgG) specific immunoglobulin using a HCV enzymelabeled antigen test (ForesightEIAUSA) and anti HIV Abs (IgG) using enzymelabeled antigen test (ForesightEIAUSA). The frequency of HBV infection in the first year was not significant between males (111%) and females (000%)(P = 0295). About HCV also there are no significant differences between males (1263%) and females (931%)(P = 0347). After one year of follow up the frequencies of HBV and HCV were not significant between two sexes. Additionally none of the patients had an HIV infection. This study brings to light that HBV and HCV have the same frequencies in both genders and lower occurrence with time. Furthermore HIV was not detected in those patients.

    Anemia is a common complication in uremic patients. Erythropoietin therapy is prescribed in these cases; however, this treatment is not successful in iron deficient patients. Ferritin-based diagnosis of iron deficiency in these patients is a challenging task, as serum ferritin level may be high due to chronic inflammation and mask iron deficiency. In the current study we evaluated the credibility of another indicator of body iron supply, serum transferrin receptor, in hemodialysis patients in two University-based Hospitals in North of Iran. In a cross-sectional study, 53 hemodialysis patients with a mean age of 56 +/- 18.7 years and 30 persons with iron deficiency and normal renal function with a mean age of 20.1 +/- 14.4 years were examined. All hemodialysis patients were on hemodialysis 2-3 times per week for 3-4 hours. All cases were examined for blood hemoglobin content, serum iron, CRP, serum ferritin and serum transferrin receptor levels. The reference ranges introduced by manufacturers were considered as standard ranges for analysis of the results. Using one sample T-test and Fisher's exact test, data were analyzed. p<0.05 was considered as significant. Hemodialysis patients had blood hemoglobin content below normal range (p<0.05 for men, p<0.001 for women) and CRP levels above normal range (p<0.001). In hemodialysis patients, serum ferritin level was significantly higher than control group (p<0.001), whilst serum transferrin receptor levels in the two groups were not significantly different (p=0.69), and both were above defined normal upper limit (p<0.001 for iron deficient patients; p<0.05 for hemodialysis patients). This study showed measurement of serum ferritin in the presence of chronic inflammation induced by renal failure cannot be a credible indicator of body iron supply, while under this certain condition serum transferrin receptor can more appropriately reflect the amount of body iron supply.

    The purpose of this study was to construct and test a hypothetical model of self-management in patients with hemodialysis based on the Self-Regulation Model and resource-coping perspective. Data were collected from 215 adults receiving hemodialysis in 17 local clinics and one tertiary hospital in 2016. The Hemodialysis Self-management Instrument, the Revised Illness Perception Questionnaire, Herth Hope Index and Multidimensional Scale of Perceived Social Support were used. The exogenous variable was social context; the endogenous variables were cognitive illness representation, hope, self-management behavior, and illness outcome. For data analysis, descriptive statistics, Pearson correlation analysis, factor analysis, and structural equation modeling were performed. The hypothetical model with six paths showed a good fitness to the empirical data: GFI=.96, AGFI=.90, CFI=.95, RMSEA=.08, SRMR=.04. The factors that had an influence on self-management behavior were social context (β=.84), hope and cognitive illness representation (β=.37 and β=.27) explaining 92.4% of the variance. Self-management behavior mediated the relationship between psychosocial coping resources and illness outcome. This research specifies a more complete spectrum of the self-management process. It is important to recognize the array of clinical resources available to support patients' self-management. Healthcare providers can facilitate self-management through collaborative care and understanding the ideas and emotions that each patient has about the illness, and ultimately improve the health outcomes. This framework can be used to guide self-management intervention development and assure effective clinical assessment. © 2017 Korean Society of Nursing Science

    Both diabetes and hemodialysis can seriously impair patients' health related quality of life (HRQOL). This study seeks to obtain data which will help to address the factors associated with impaired HRQOL in hemodialysis patients with diabetes in Palestine. A cross-sectional study was performed in multiple centers in the period from November 2016 to June 2017. We utilized the Arabic version of EuroQoL 5 Dimensions 5 Levels (EQ-5D-5L) scale and EuroQol-visual analogue scale (EQ-VAS) to measure patients' HRQOL. The study was conducted in six dialysis centers in the North of West Bank, Palestine. Descriptive and comparative statistics were used to describe clinical and socio-demographic features of patients. Multiple linear regression analysis was used to determine the association between clinical and socio-demographic factors and HRQOL score. One hundred and forty one diabetic patients undergoing hemodialysis were enrolled in our study. Overall, 52.5% of them (74 patients) were males; the patients had a mean age of 60.32 with 52.5% of them aged below 60. The mean ± standard deviation of EQ-5D-5L index and EQ-VAS score was 0.314 ± 0.4 and 50.85±22.43, respectively. The findings of this study suggest that female patients, uneducated patients, unemployed patients, unmarried patients, and patients with more chronic diseases and comorbidities had a significant poor HRQOL scores (p values <0.05). Variables such as marital status and occupational status were significantly (p < 0.05) associated with the QOL score. More specifically, married status and employed patients positively associated with QOL score (β = 0.22; p = 0.016 and β = 0.27; p = 0.013, respectively). Among diabetic patients undergoing hemodialysis, married status and being employed were associated with modestly higher scores of QOL. We recommend that healthcare providers give more attention to diabetic dialysis patients who are unemployed and unmarried, as they are at a higher risk of having impaired HRQOL.

    Occult hepatitis B viral infection is the presence of hepatitis B viral nucleic acids in the serum and/or liver in the absence of hepatitis B surface antigen. The study aimed to determine the prevalence of occult hepatitis B virus infection among hepatitis C virus-negative hemodialysis patients and to identify their genotypes. of 144 patients on maintenance hemodialysis, 50 hepatitis B surface antigen and hepatitis C virus nucleic acid-negative patients were selected according to strict inclusion criteria to avoid the effect of confounding variables. The following investigations were done: serum AST and ALT; HBsAg; HBcAb; HCV-Ab; HCV-RNA; and HBV-DNA. Positive hepatitis B viral nucleic acid was confirmed in 12/144 (8.3%) hemodialysis patients and 12/50 (24%) in our study group (occult infection). Mean hemodialysis periods for negative patients and occult hepatitis B virus patients were 27.3±18.8 and 38.4±8.14 months, respectively, and this difference was significant (p-value=0.02). Mean alanine transaminase levels were 20.27±5.5IU/L and 25.3±9.6 in negative patients and occult infection patients, respectively. This difference was non-significant. Aspartate transaminase levels were 21.4±10.2IU/L and 27.3±4.6IU/L, respectively, in negative patients and infected patients; this difference was significant (p-value=0.03). Half (6/12) of the positive samples belonged to genotype 'B', 33.3% (4/12) to 'C', and 16.6% (2/12) to genotype 'D'. OBI is likely among hemodialysis patients even without HCV coinfection (24%). Genotype D cannot be the only genotype distributed in Upper Egypt, as the current study reported relatively new results that 50% of the patients with occult B carry genotype B, 33.3% carry genotype C and only 16.6% carry genotype D.

    This study aimed to compare the effects of relaxation techniques on fatigue in hemodialysis patients. This clinical trial study was conducted on 105 hemodialysis patients. The subjects were categorized into three groups as: relaxation, aromatherapy and control. In the relaxation group, Benson muscle relaxation techniques were employed; in the aromatherapy group, the inhalation of two drops of 5% lavender essential oil used and the control group only received regular healthcare actions. Data collected by using brief fatigue inventory, before and after the intervention. Results of the current study indicated significant differences in the mean of changes in fatigue scores before and after the intervention between the relaxation and aromatherapy groups, but the difference was insignificant in the control group. Aromatherapy with lavender essential oil can decrease the level of fatigue in the patients undergoing hemodialysis compared to Benson relaxation techniques. Copyright © 2018 Elsevier Ltd.

    To explore the relation between the frequencies of apolipoprotein E (ApoE) alleles and the occurrence of depression in patients undergoing hemodialysis in a Chinese population. We examined the ApoE alleles in a sample of 288 subjects: 72 patients with depression under hemodialysis, 74 patients without depression under hemodialysis, 75 patients with depression under nondialytic treatment and 67 patients without depression under nondialytic treatment. The depression state was assessed using the Center for Epidemiological Studies Depression (CES-D) scale. Associations between the occurrence of depression and the frequencies of ApoE alleles were examined using multinomial logistic regression models with adjustment of relevant covariates. Information about sociodemographics, clinical data, vascular risk factors and cognitive function was also collected and evaluated. The frequencies of ApoE-ɛ2 were significantly different between depressed and non-depressed patients irrespective of dialysis (p < 0.05), but no significant difference was found in the frequencies of ApoE-ɛ4 (p > 0.05). Serum ApoE levels were significantly different between depressed and non-depressed patients in the whole sample (p < 0.05). Multinomial logistic regression models showed significant association between the frequency of ApoE-ɛ2 and the occurrence of depression in the Chinese population after control of relevant covariates, including age, sex, educational level, history of smoking and drinking, vascular risk factors and cognitive function. No association between the frequency of ApoE-ɛ4 and the occurrence of depression was found in patients undergoing hemodialysis. Further research is needed to find out if ApoE-ɛ2 acts as a protective factor in Chinese dialysis population since it might decrease the prevalence of depression and delay the onset age.

    Control of serum phosphate is important for patients on hemodialysis. The aim of the study was to determine if education based on phosphorus-reducing techniques in food preparation and thermal processing, and accordingly prepared and applied diets, will lead to better outcomes than a standard education program to improve phosphate control in patients on hemodialysis. Forty-seven patients on hemodialysis were divided between an intervention and a control group. All subjects received training about nutrition for hemodialysis patients by trained dietitian. In addition, subjects in the intervention group received additional training in phosphorus-reducing techniques in food preparation and received two hospital meals prepared using suggested cooking methods to reduce the phosphate content of food during dialysis treatment. Serum phosphate, serum albumin, and anthropometric parameters were measured, while nPCR was calculated, at the baseline and during the 1-year study. No differences in serum phosphate levels were observed between intervention (1.68 mmol/L [1.48-2.03]) and control group (1.88 mmol/L [1.57-2.2]) at baseline (P = 0.130). Although not statistically significant between groups the mean reduction was more apparent in the intervention group (-0.3 mmol/L (-0.4 to 0.1) vs. -0.2 (-0.5 to 0.1)), and lead to significantly reduction of phosphate binder therapy. During the study, the nPCR and anthropometric status of the patients did not change significantly. Providing additional education to hemodialysis patients on the specific cooking methods and accordingly prepared meals may decrease serum phosphate levels without significantly affecting nutritional status which may be useful in helping to prevent and treat hyperphosphatemia. © 2016 International Society for Hemodialysis.

    Nutritional status has a significant impact on the outcomes in the dialysis population. The aim of this study was to evaluate the association between body composition and a one-year survival of hemodialysis patients. Forty-eight patients with chronic kidney disease stage V treated with hemodialysis for more than three months were included. Body composition was assessed by bioimpedance spectroscopy (Body Composition Monitor, Fresenius Medical Care). Blood samples for serum creatinine, serum albumin, serum prealbumin, high sensitivity C-reactive protein (hsCRP), interleukin 6 (IL-6), insulin-like growth factor 1(IGF-1) concentrations were taken before the midweek dialysis session. Over the course of a one-year observation, seven patients died. We observed a significantly lower lean tissue index (LTI) (p = .013) and higher IL-6 (p = .032) and hsCRP levels (p = .011) among the patients who died. The remaining biochemical markers did not differ between these two groups. Kapplan-Meier analysis revealed a worse survival rate in patients with sarcopenia (lower than the 10th percentile for their age and gender) in comparison with those with normal LTI. However, it was not of statistical significance (p = .055). LTI inversely correlated with age and IL-6 and positively with IGF-1. Sarcopenia defined as decreased LTI, is a relatively common condition among patients undergoing maintenance hemodialysis, it can also be associated with a lower one-year survival rate. Decreased lean tissue mass can be associated with old age, lower IGF-1 levels and higher IL-6 levels. Body composition assessment may provide prognostic data for hemodialysis patients.

    Introduction Inspiratory muscle function may be affected in patients with End-Stage Renal Disease (ESRD), further worsening the functional loss in these individuals. However, the impact of inspiratory muscle weakness (IMW) on the functional capacity (FC) of hemodialysis patients remains unknown. Thus, the present study aimed to evaluate the impact of IMW on FC in ESRD patients undergoing hemodialysis. Materials and methods ESRD patients on hemodialysis treatment for more than six months were evaluated for inspiratory muscle strength and FC. Inspiratory muscle strength was evaluated based on maximal inspiratory pressure (MIP). IMW was defined as MIP values less than 70% of the predicted value. FC was evaluated using the Incremental Shuttle Walk test (ISWT). Patients whose predicted peak oxygen uptake (VO2peak) over the distance walked during the ISWT was less than 16mL/kg/min were considered to have FC impairment. Associations between variables were assessed by linear and logistic regression, with adjustment for age, sex, body mass index (BMI), presence of diabetes and hemoglobin level. Receiver-operating characteristic (ROC) analysis was used to determine different cutoff values of the MIP for normal inspiratory muscle strength and FC. Results Sixty-five ERSD patients (67.7% male), aged 48.2 (44.5–51.9) years were evaluated. MIP was an independent predictor of the distance walked during the ISWT (R2 = 0.44). IMW was an independent predictor of VO2peak < 16mL/kg/min. (OR = 5.7; p = 0.048) in adjusted logistic regression models. ROC curves showed that the MIP cutoff value of 82cmH2O had a sensitivity of 73.5% and specificity of 93.7% in predicting normal inspiratory strength and a sensitivity and specificity of 76.3% and 70.4%, respectively, in predicting VO2peak ≥ 16mL/kg/min. Conclusions IMW is associated with reduced FC in hemodialysis patients. Evaluation of the MIP may be important to functional monitoring in clinical practice and can help in the

ESRD patients on hemodialysis treatment for more than six months were evaluated for inspiratory muscle strength and FC. Inspiratory muscle strength was evaluated based on maximal inspiratory pressure (MIP). IMW was defined as MIP values less than 70% of the predicted value. FC was evaluated using the Incremental Shuttle Walk test (ISWT). Patients whose predicted peak oxygen uptake (VO2peak) over the distance walked during the ISWT was less than 16mL/kg/min were considered to have FC impairment. Associations between variables were assessed by linear and logistic regression, with adjustment for age, sex, body mass index (BMI), presence of diabetes and hemoglobin level. Receiver-operating characteristic (ROC) analysis was used to determine different cutoff values of the MIP for normal inspiratory muscle strength and FC. Sixty-five ERSD patients (67.7% male), aged 48.2 (44.5-51.9) years were evaluated. MIP was an independent predictor of the distance walked during the ISWT (R2 = 0.44). IMW was an independent predictor of VO2peak < 16mL/kg/min. (OR = 5.7; p = 0.048) in adjusted logistic regression models. ROC curves showed that the MIP cutoff value of 82cmH2O had a sensitivity of 73.5% and specificity of 93.7% in predicting normal inspiratory strength and a sensitivity and specificity of 76.3% and 70.4%, respectively, in predicting VO2peak ≥ 16mL/kg/min. IMW is associated with reduced FC in hemodialysis patients. Evaluation of the MIP may be important to functional monitoring in clinical practice and can help in the stratification of patients eligible to perform exercise testing.

  1. Blood volume-monitored regulation of ultrafiltration in fluid-overloaded hemodialysis patients: study protocol for a randomized controlled trial

    Background Data generated with the body composition monitor (BCM, Fresenius) show, based on bioimpedance technology, that chronic fluid overload in hemodialysis patients is associated with poor survival. However, removing excess fluid by lowering dry weight can be accompanied by intradialytic and postdialytic complications. Here, we aim at testing the hypothesis that, in comparison to conventional hemodialysis, blood volume-monitored regulation of ultrafiltration and dialysate conductivity (UCR) and/or regulation of ultrafiltration and temperature (UTR) will decrease complications when ultrafiltration volumes are systematically increased in fluid-overloaded hemodialysis patients. Methods/design BCM measurements yield results on fluid overload (in liters), relative to extracellular water (ECW). In this prospective, multicenter, triple-arm, parallel-group, crossover, randomized, controlled clinical trial, we use BCM measurements, routinely introduced in our three maintenance hemodialysis centers shortly prior to the start of the study, to recruit sixty hemodialysis patients with fluid overload (defined as ≥15% ECW). Patients are randomized 1:1:1 into UCR, UTR and conventional hemodialysis groups. BCM-determined, ‘final’ dry weight is set to normohydration weight −7% of ECW postdialysis, and reached by reducing the previous dry weight, in steps of 0.1 kg per 10 kg body weight, during 12 hemodialysis sessions (one study phase). In case of intradialytic complications, dry weight reduction is decreased, according to a prespecified algorithm. A comparison of intra- and post-dialytic complications among study groups constitutes the primary endpoint. In addition, we will assess relative weight reduction, changes in residual renal function, quality of life measures, and predialysis levels of various laboratory parameters including C-reactive protein, troponin T, and N-terminal pro-B-type natriuretic peptide, before and after the first study phase (secondary

    Stroke incidence in hemodialysis patients is up to 10 times greater than in the general population and is associated with a worse prognosis. Factors influencing stroke risk by subtype and subsequent prognosis are poorly described in the literature. Retrospective single-center cohort study. 2,384 established maintenance hemodialysis patients at a single center from January 1, 2002, to June 1, 2009. Patient demographics, comorbid conditions. Incidence of acute stroke (International Classification of Diseases, 9th Revision codes 430, 431, 432.9, 433.1, and 434.1 with evidence of compatible neuroimaging), patient survival. Cumulative patient survival, incidence of acute fatal and nonfatal stroke. 127 strokes occurred during 9,541 total patient-years of follow-up. First (incident) stroke occurred at a rate of 14.9/1,000 patient years (95% CI, 12.2-17.9) with a predominance of ischemic compared with hemorrhagic subtypes (11.2 vs 3.7/1,000 patient-years). 54% of hemorrhagic strokes occurred in patients of South Asian ethnicity compared with ischemic strokes, which occurred predominantly in white patients (45% of events). Diabetes mellitus (HR, 1.92; 95% CI, 1.29-2.85; P = 0.001) and prior cerebrovascular disease (HR, 4.54; 95% CI, 3.07-6.72; P < 0.001) were independently associated with incident cerebrovascular accident on multivariate analysis. Acute stroke was associated with worse patient survival (HR, 3.26; 95% CI, 2.47-4.30; P < 0.001) and overall 1-year mortality of 24%, which was significantly worse in patients with hemorrhagic events (39% vs 19% mortality for ischemic subtypes). Serum albumin level >3.5 g/L (HR, 0.38; 95% CI, 0.19-0.76; P = 0.007) and C-reactive protein level >3.0 mg/l (HR, 1.36; 95% CI, 1.12-1.64; P = 0.002) influenced survival after stroke on multivariate analysis. Retrospective analysis of data cannot prove causality. The high incidence of stroke in hemodialysis patients is associated with high mortality, especially hemorrhagic subtypes. Strict

    Poor nutritional status has been associated with worse patient survival in maintenance hemodialysis patients. Anthropometric values are important nutritional measures, incorporating muscle and fat mass. However, the association of changes in anthropometry, including midarm circumference (MAC) and skinfold measurements, with mortality in hemodialysis patients remains unknown. Accordingly, we explored this association in the Hemodialysis (HEMO) Study. Post hoc analysis of cohort data from a clinical trial. 1,846 hemodialysis patients enrolled in the HEMO Study. MAC and skinfold measurements. Longitudinal changes in MAC and skinfolds were jointly modeled using repeated measures and survival modeling. Time-to-event outcomes were all-cause mortality, cardiac death and hospitalization, and infection-related death. Mean MAC was 30.1 cm, and mean baseline sum of subscapular, biceps, and triceps skinfolds was 42.4 mm. During a median follow-up of 2.5 years, there were 845 deaths. During follow-up, MAC and the skinfold measurement declined 0.26 cm and 1.1 mm per year, respectively. Declines in MAC (per cm) and skinfold (per mm) measurements were associated with higher all-cause mortality (HRs of 1.58 [95% CI, 1.29-1.94; P < 0.001] and 1.06 [95% CI, 0.99-1.13; P = 0.09], respectively), poorer cardiac outcomes (HRs of 1.49 [95% CI, 1.23-1.81; P < 0.001] and 1.05 [95% CI, 0.99-1.10; P = 0.09], respectively), and higher infection-related hospitalization (HRs of 2.45 [95% CI, 1.55-3.88; P < 0.001] and 1.16 [95% CI, 0.98-1.37; P = 0.08], respectively). The association between declining MAC and skinfold with patient survival was most notable for those with body mass index (BMI) ≤25 kg/m2 (HRs of 2.41 [95% CI, 1.81-3.19; P < 0.001] and 1.22 [95% CI, 1.10-1.35; P < 0.001], respectively). Prevalent dialysis patients only, excluding individuals weighing >85 kg. Declines in skinfold thickness were not associated significantly with outcomes except for participants with BMI ≤25 kg/m2

    This study aimed to evaluate the prevalence of vitamin D inadequacy in patients receiving maintenance hemodialysis and peritoneal dialysis (PD) and its association with inflammatory and nutritional factors. A total of 176 hemodialysis and 32 PD patients participated in the study. Serum levels of 25-hydroxyvitamin D, albumin, parathyroid hormone, calcium, phosphorus, high-sensitivity C-reactive protein (HSCRP), and neutrophil-lymphocyte ratio (NLR) were measured. Data on body mass index were also collected. Stepwise multiple logistic regression analysis was used to identify predictors for 25-hydroxyvitamin D deficiency and its relationship with the nutritional and inflammatory factors. No significant association was found between 25-hydroxyvitamin D and age, body mass index, serum calcium, serum phosphorus, parathyroid hormone, serum albumin, dialysis quality, and duration of dialysis; while NLR and HSCRP were significantly associated with 25-hydroxyvitamin D in the hemodialysis patients only (P < .001 and P = .001, respectively). A positive correlation was found between NLR and HSCRP in both hemodialysis and PD patients. (r = 0.817; P < .001). This association was confirmed between an NLR greater than 3 and an HSCRP level greater than 3. Vitamin D deficiency was highly prevalent in our dialysis patients, and inadequate level of vitamin D was associated with inflammatory factors such as HSCRP and NLR in both hemodialysis and PD patients. An easy and inexpensive test of an NLR greater than 3 could be used as a measure of inflammation instead of HSCRP in both PD and hemodialysis patients.

    The average life expectancy of a person on hemodialysis is less than 3 years and hasn't changed in 20 years. The Hemodialysis (HEMO) trial, a randomized trial to determine whether increasing urea removal to the maximum practical degree through a 3-times-a-week schedule, showed no difference in mortality in the treatment and control groups. Investigators speculated that the increment in functional waste removal in the HEMO study was too small to produce improvements in mortality. To test this hypothesis, the NIDDK funded the Frequent Hemodialysis Network, a consortium of centers testing whether patients randomized to intensive dialysis would demonstrate improved (reduced) left ventricular LV mass and quality of life. The trial has two arms: the daily (in-center) and the home (nocturnal) arms. Each arm has patients randomized to conventional dialysis or 6 days (or nights) of dialysis. The results of the HEMO trial will be reported in the fall of 2010. PMID:21686215

    Fluid control in patients on dialysis is an important predictor of outcome but is a difficult restriction to achieve. The authors examined the association between dialysis staff encouragement and fluid control adherence in patients on hemodialysis. This cross-sectional study used the dialysis staff encouragement subscale (DSE). The outcome measure was intradialytic weight loss (IWL) of dry weight (DW), with nonadherence defined as IWL/DW greater than 5.7%. Predictors of nonadherence were identified using logistic regression. Odds ratio (OR) was for the occurrence of nonadherence as it correlated with a one standard deviation (SD) decrease in scale score. Seventy-two patients on hemodialysis participated, 45 men (62.5%) and 27 women. The crude OR in DSE score was 1.75 (95% confidence interval [CI]: 1.02 to 3.0) and adjusted odds ratio was 2.51 (95% CI: 0.99 to 6.34). Dialysis staff encouragement is important in improving fluid control adherence.

    Background: Patients with chronic renal failure (CRF) were on maintenance invasive haemodialysis (HD) procedure. This procedure by itself affects immunity of the patients and became more susceptible to viral infections. Aim of the study: to investigate the occurrence of HBV, HCV and HIV infections in patients with hemodialysis. Patients and methods: A retrospective study of 430 end-stage renal failure patients, referred to hemodialysis department at Al-Kindy Teaching Hospital, Baghdad-Iraq from Junuary-2015 to Junuary-2017. Patients were investigated for HBs-Ag using enzyme-labeled antigen test (Foresight-EIA-USA ), HCV- Abs (IgG) specific immunoglobulin using a HCV enzyme-labeled antigen test (Foresight-EIA-USA) and anti HIV Abs (IgG) using enzyme-labeled antigen test (Foresight-EIA-USA). Results: The frequency of HBV infection in the first year was not significant between males (1.11%) and females (0.00%)(P = 0.295). About HCV also there are no significant differences between males (12.63%) and females (9.31%)(P = 0.347). After one year of follow up the frequencies of HBV and HCV were not significant between two sexes. Additionally, no any one of the patients had HIV infection. Conclusions: This study brings a light on that HBV and HCV were having the same frequencies in both genders and lower occurrence with time. Furthermore, HIV was not detected in those patients.

    Increased levels of C-Reactive Protein are found in 30-60% on hemodialysis patients and it is closely associated with the progression of atherosclerosis, cardiovascular morbidity and mortality. Non enzymatic antioxidants are antioxidants which primarily retain potentially dangerous ions of iron and copper in their inactive form and thereby prevent its participation in the production of free radicals. The aim of the study was to examine the relationship of CRP and non enzymatic antioxidants (albumin, ferritin, uric acid and bilirubin) i.e. examine the importance of CRP as a serum biomarker in assessing the condition of inflammation and its relationship to antioxidant protection in patients on hemodialysis. The study was cross-sectional, clinical, comparative and descriptive. The study involved 100 patients (non diabetic) on chronic hemodialysis. The control group consisted of 50 subjects without subjective and objective indicators of chronic renal disease. In all patients, the concentration of CRP as well as concentrations of non enzymatic antioxidants were determined. In the group of hemodialysis patients 60% were men and 40% women. The average age of hemodialysis patients was 54.13 ± 11.8 years and the average age of the control group 41.72 ± 9.8 years. The average duration of hemodialysis treatment was 91.42 ± 76.2 months. In the group of hemodialysis patients statistically significant, negative linear correlation was determined between the concentration of CRP in and albumin concentration (rho = -0.251, p = 0.012) as well as negative, statistics insignificant, linear correlation between serum CRP and the concentration of uric acid (r = -0.077, p = 0.448). Furthermore, the positive, linear correlation was determined between serum CRP and ferritin (r = 0.159, p = 0.114) and positive linear correlation between CRP and total serum bilirubin (r = 0.121, p = 0.230). In the control group was determined a statistically significant, positive, linear correlation

    Cognitive impairment is defined as a newly appeared deficit in at least two areas of cognitive functions, including disturbances in memory, executive functioning, attention or speed of information processing, perceptual motor abilities, or language. Cognitive impairment is highly prevalent in ESRD patients when compared with the general population. It has also been associated with a decreased quality of life. Cognitive functions in patients with ESRD showed improvement with dialysis and renal transplantation. These findings illustrate the potential importance of evaluating and comparing the effects of hemodialysis and transplantation regarding cognitive performance and thus quality of life in ESRD patients and normal subjects. This study was carried out in 100 patients (50 ESRD patients on regular hemodialysis for at least 6 months and 50 post-transplant patients who had maintained successful kidney graft for at least 3 months). All patients underwent laboratory and psychometric scoring tests, including trail making test part A, trail making test part B, digit span, and mini-mental state examination. Thirty healthy adults matched by age and sex served as a control group. The results showed significant differences in cognitive function tests results between transplant and hemodialysis patients (P<0.01), suggesting that transplant patients were superior in their cognitive performance, with the correction of anemia being the most important factor for improving cognitive performance in both groups. There were no significant differences between transplant patients and control subjects in psychometric measures (P>0.05). Renal transplantation as a modality of treatment, in ESRD patients, is superior to hemodialysis in terms of cognitive performance improvement. Copyright © 2015 Sociedad Española de Nefrología.

    Bloodstream infections are the second most common cause of death among patients on hemodialysis. This study aimed to evaluate the incidence of and risk factors associated with central venous catheter-related infections in patients undergoing hemodialysis, and to identify and characterize the type and antimicrobial susceptibility profiles of the primary microorganisms isolated during one year of follow-up. A prospective cohort study was conducted in 2014 in a hemodialysis referral center. We included 200 outpatients with acute kidney injury who had no permanent venous access. A nurse assessed the patients for signs of infection three times per week during dressing changes. The clinicopathologic characteristics of patients with and without local or systemic infection were compared. Fifty-five episodes of catheter-related infections occurred in 43 (22%) patients; 38 (69%) were bloodstream infections and 17 (31%) were local infections. Thirty-two (75%) patients with infection had femoral vein catheter placement. In total, 6,240 hemodialysis sessions were performed; the rates of primary bloodstream and local infection were 6.1 and 2.7 episodes per 1,000 patients on daily dialysis, respectively. In the univariate analysis, diabetes was significantly associated with the development of infection, while level of education, ethnicity, age, and sex were not. Gram-negative bacteria were primarily isolated from blood culture specimens (55% of samples). Of the Gram-negative isolates, 56% were resistant to the carbapenems. We identified a high incidence of catheter-related infections caused by resistant microorganisms in patients undergoing hemodialysis via central venous catheters.

    We are in the era of rapid aging of the global population. Elderly asthmatic patients have an increased frequency of hospitalization and a high mortality rate. In this review, we focus on comorbidities and treatment issues in terms of the predictors of asthma control in the elderly. Some frequent comorbidities, such as chronic obstructive pulmonary disease, chronic sinusitis, obesity, and depression, are associated with uncontrolled asthma in elderly asthmatic patients. Smoking status in elderly asthmatic patients was associated with more frequent exacerbations. Management of comorbidities should be taken into account when we treat elderly asthmatic patients. Low treatment adherence, which is common in elderly asthmatic patients, predicts poor asthma control status. A poor knowledge about asthma, cognitive function impairment, and inappropriate inhaler technique result in low treatment adherence. Polypharmacy is associated with low treatment adherence, adverse drug reactions, and drug-drug interactions, and it is supposed to be a predictor of asthma control. Multifactorial assessments, including comorbidities, treatment adherence, and polypharmacy, are important for better asthma control in elderly asthmatic patients. Further studies on the strategy for the management of elderly asthmatic patients in a real-world setting are warranted.

    The stagnant mortality rate of the last decade and the increased prevalence of aged people among hemodialysis patients motivated the present study to determine the relation of gender and age with the quality of life (QL) of patients with chronic kidney failure treated with hemodialysis. From the sample of 107 individuals who underwent regular hemodialysis in a Dialysis Unit in the interior of the state of Ceará, Brazil, the Medical Outcomes Study Questionnaire 36-Item Short Form Health Survey (SF-36) was used to assess quality of life. Pearson's correlation coefficient was used to calculate and to test the linear correlation between age and the score generated by the SF-36. The score for gender was compared by the t test and the Mann-Whitney when indicated. There was no difference between the score related to gender. There was no negative and linear correlation between age and the dimensions of QL named: Physical Functioning (r=-0.289, p=0.003), Physical Role (r=-0.224, p=0.020), Body Pain (r=0.252, p=0.008), General Health (r=-0.245, p<0.001), Vitality (r=-0.334, p<0.001) and Social Functioning (r=-0.270, p=0.005). There was no correlation between age and the dimensions: Role of Emotions (r=-0.149, p=0.125) and Mental Health (r=-0.158, p=0.103). Gender did not correlate with the level of QL among chronic hemodialysis patients, while there was a linear and negative correlation between age and the dimensions relating to the physical aspect of the QL.

    Background The elderly hemodialyzed population is growing. However, little is known about the relationship between hemoglobin level and survival according to age. We investigated the effect of age on the relationship between hemoglobin and survival within the Japan Dialysis Outcomes and Practice Patterns Study (DOPPS) cohort. Methods We enrolled the entire Japan DOPPS phases 3 and 4 population. Patients were divided by the age of 75 years into two groups. Cox's proportional hazard model was used with hemoglobin at every 4 months treated as a time-dependent variable. The interaction of age and hemoglobin was analyzed. Results We included 3341 patients in the analyses. The primary outcome occurred in 567 patients during the median follow-up of 2.64 years. Hemoglobin of entire population was 10.3 ± 1.3 g/dL. The median of epoetin dose was 3000 IU/week. Interaction was found between ages stratified by the age of 75 years and hemoglobin values (P = 0.045) with use of Cox's proportional hazard model. The nonelderly population had poorer prognosis with hemoglobin <10 g/dL, while elderly population only with hemoglobin <9 g/dL. For both hemoglobin strata <9, ≥9 and <10 g/dL, interactions between age and hemoglobin were significant. Subgroup analysis indicated that interaction between age and Hb levels was observed only in the nondiabetic nephropathy group. Several sensitivity analyses demonstrated a similar trend with the original analyses and reinforced the robustness. Conclusions The elderly population might tolerate low hemoglobin levels. Our findings open the way for further investigation of individualized anemia management. PMID:25150218

    Background: Despite being frequently described, Restless Leg Syndrome (RLS) in patients, who are on hemodialysis, is a common disease which, has not been well documented in Iran. Objectives: The current study aimed to investigate the prevalence of RLS and its sleep disorders in Iranian patients on hemodialysis. Patients and Methods: In this multicenter cross sectional study, 397 consecutive patients on hemodialysis were evaluated by face-to-face interviews. RLS was diagnosed using the International RLS Study Group (IRLSS) criteria. In addition, three validated sleep disorder questionnaires (Insomnia Severity Index, Epworth sleepiness scale and Pittsburgh sleep quality index) were completed by the patients. Results: One hundred-twenty-six patients with RLS (31.7%; mean age 57.6 ± 15.4 years) participated in the current study. RLS mostly occurs in females (P < 0.001). RLS cases showed poorer quality of sleep (Pittsburgh Sleep Quality Index > 5, P = 0.001), higher scores of Epworth Sleepiness Scale (P < 0.001) and insomnia severity index (P = 0.001). Except thyroid gland dysfunction (P < 0.03, OR ≈ 2.50) and anti-hypertensive medications (P < 0.01, OR ≈ 1.7), there were no significant differences between age, duration of dialysis, etiology of renal insufficiency, intake of nicotine, alcohol or caffeine, and other associated comorbidities between the patients with and without RLS. Conclusions: In the current study, prevalence of RLS was near the weighted-mean prevalence of other studies (mean 30%, range 8%t-52%). This is not just racial variability and may attribute to narrow or wide definition of the disease, plus variations of the prevalence recording time, and sometimes not using the standard criteria or standard interview.

    Inflammation is closely associated with cardiovascular disease, the leading cause of mortality in patients with CKD. Serum decoy receptor 3 (DcR3) is a member of the TNF receptor superfamily. CKD patients have higher levels of DcR3 than the general population, but whether DcR3 predicts mortality in CKD patients on hemodialysis has not been explored. DcR3 levels were measured in 316 prevalent hemodialysis patients who were followed up from November 1, 2004, to June 30, 2009, for cardiovascular and all-cause mortality. The baseline DcR3 concentration showed a strong positive correlation with inflammatory markers including high-sensitivity C-reactive protein, IL-6, intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1). During a follow-up period of 54 months, 90 patients died (34 cardiovascular deaths). Kaplan-Meier survival analysis showed higher cardiovascular and all-cause mortality in patients with higher DcR3 levels. The hazard ratios (95% confidence intervals) of the highest versus lowest tertiles of DcR3 were 2.8 (1.1-7.3; P for trend=0.04) for cardiovascular mortality and 2.1 (1.1-3.7; P for trend=0.02) for all-cause mortality, respectively. Based on the minimal increase in the area under the receiver operating characteristic curve from 0.79 to 0.80, the addition of DcR3 to established risk factors including VCAM-1, albumin, and IL-6 does not improve the prediction of mortality. Higher DcR3 levels strongly correlate with inflammation and independently predict cardiovascular and all-cause mortality in CKD patients on hemodialysis.

    Despite the evidence that phosphate binder (PB) is associated with improved outcomes many hemodialysis patients do not adhere to prescribed PB regimen. Therefore, barriers to PB adherence should be identified and eliminated. The purpose of this study was to evaluate PB adherence among hemodialysis patients and to explore potentially modifiable factors associated with low PB adherence. A cross-sectional study (502 patients) was performed in four dialysis units in Salvador, Brazil, using data from the second phase of the Prospective Study of the Prognosis of Chronic Hemodialysis Patients (PROHEMO). Patients were categorized as adherent or non-adherent to PB based on their responses to a semi-structured questionnaire. Non-adherence to PB was observed for 65.7% of the patients. After adjustments for numerous covariates, cerebrovascular disease (odds ratio (OR), 3.30; 95% confidence interval (CI), 1.03-10.61), higher PTH (OR per each 300 pg/mL, 1.14; 95% CI, 1.01-1.28), lack of comprehension of the appropriate time to use PB (OR, 7.09; 95% CI, 2.10-23.95) and stopping PB use after feeling better (OR, 4.54; 95% CI, 1.45-14.25) or feeling worse (OR, 11.04; 95% CI, 1.79- 68.03) were significantly associated with PB non-adherence. By contrast, the adjusted odds of PB non-adherence were lower for patients with more years on dialysis (OR by each 2 years, 0.87; 95% CI, 0.80-0.95), with serum phosphorus above 5.5 mg/dL (OR, 0.53; 95% CI 0.34-0.82), who referred that were encouraged by the dialysis staff to be independent (OR, 0.52; 95% CI 0.30-0.90), and reported that the nephrologist explained how PB should be used (OR, 0.20; 95% CI 0.05-0.73). The results of the present study are encouraging by showing evidence that improvement in the care provided by the dialysis staff and the attending nephrologist may play an important role in reducing the high prevalence of non-adherence to PB in maintenance hemodialysis patients. A new questionnaire is presented and may help to evaluate

    Erectile dysfunction (ED) is a common problem seen among patients on hemodialysis (HD), but it is still a taboo subject in our country. The attention given to this sexual problem remained low, and the prevalence of ED among these patients has not been well characterized. We carried out this study in order to determine the prevalence and severity of ED in HD patients. We conducted a descriptive cross-sectional study in our HD unit in March 2013. ED was evaluated using the International Index Erection Function. Thirty patients with a mean age of 49.1 years were eligible for this study. The main causes of chronic kidney disease were hypertension (62.5%) and diabetes (41.6%). The prevalence of ED was 80%, including 33.3% severe ED. Plasma levels of gonadotropins: luteinizing hormone (LH), follicule-stimulating hormone were in the standards except for one patient who had an elevated level of LH. Prolactin was elevated in four cases. ED was present in 8.4% of patients before the discovery of renal failure and in 91.6% of patients at the beginning of dialysis. For 19 patients (79.1%), the ED had increased during the dialysis sessions. A significant number of our HD patients presented with ED of varying degrees. Nephrologists should pay attention to the problem of ED in order to improve the quality of their life.

    Background Many studies have estimated the prevalence of anti-hepatitis C virus (HCV) antibody among hemodialysis (HD) patients; however, the prevalence of HCV core antigen—which indicates the presence of chronic HCV infection—is not known. Methods Standardized prevalence ratios (SPRs) for anti-HCV antibody and HCV core antigen among HD patients (n = 1214) were calculated on the basis of data from the general population (n = 22 472) living in the same area. Results The prevalences of anti-HCV antibody and HCV core antigen were 12.5% and 7.8%, respectively, in male hemodialysis patients, and 8.5% and 4.1% in female hemodialysis patients. The SPRs (95% confidence interval) for anti-HCV antibody and HCV core antigen were 8.39 (6.72–10.1) and 12.9 (9.66–16.1), respectively, in males, and 5.42 (3.67–7.17) and 8.77 (4.72–12.8) in females. Conclusions The prevalences of chronic HCV infection among male and female HD patients were 13-fold and 9-fold, respectively, those of the population-based controls. Further studies should therefore be conducted to determine the extent of chronic HCV infection among HD patients in other populations and to determine whether chronic HCV infection contributes to increased mortality in HD patients.

    BACKGROUND: Previous studies showed that family caregivers of hemodialysis patients have low level of quality of life. However, these caregivers are mostly neglected, and no studies are available on improving their quality of lives. Therefore, this study aimed to examine the effects of supportive educative program on the quality of life in family caregivers of hemodialysis patients. MATERIALS AND METHODS: A randomized controlled clinical trial was conducted on 76 family caregivers of hemodialysis patients referred to Shahid Hasheminejad Hemodialysis Center in Tehran, Iran in 2015. The subjects were equally allocated into two groups of 38. Caregivers of patients were randomly assigned into the intervention group and the control group. The intervention group received six training sessions on supportive educative program. Both groups answered demographic information and short form-36 questionnaires before and 6 weeks after the intervention. Descriptive statistics, Chi-square and Fisher exact tests, independent samples t-test, and t-couple, was used to analyze the data. RESULTS: No significant difference was found between the baseline mean scores of “quality of life” of the intervention and the control groups (P = 0.775). However, the mean scores of quality of life of the intervention group increased at the end of the study, and the two groups were significantly different in this regard (P < 0.001). CONCLUSIONS: Supportive educative program improved the quality of life in caregivers of hemodialysis patients. Therefore, it is suggested that health system managers encourage their staff to implement such programs for improving the health status of the caregivers. PMID:29114548

    The cardiothoracic ratio (CTR) and serum aluminum levels are both associated with mortality in hemodialysis patients. However, limited data regarding the association between serum aluminum levels and the CTR have been published to date. Therefore, we aimed to elucidate this association in patients on chronic hemodialysis (CHD). We investigated the association between the serum aluminum level and the CTR in CHD in a retrospective cross-sectional study of 547 Taiwanese patients on CHD. The mean age of patients was 62.5±13.2 years, with a mean hemodialysis time of 7.1±5.2 years. Among the patients, 36.9% were diabetic and 47.9% were male. After natural logarithmic transformation (ln(aluminum)), the serum aluminum level exhibited an independent and linear relationship with the CTR (β: 1.40, 95% confidence interval (CI), 0.6–2.2). A high serum aluminum level (≥6 ng/dL) was significantly associated with a CTR >0.5 in the crude analysis (odds ratio (OR): 2.15, 95% CI, 1.52–3.04) and remained significant after multivariable adjustment (OR: 2.45, 95% CI, 1.63–3.67). Moreover, the ln(aluminum) value was significantly associated with a CTR >0.5 (OR: 1.71, 95%CI, 1.28–2.29) in multivariable analysis, indicating a dose effect of aluminum on cardiomegaly. In conclusion, the serum aluminum level was independently associated with cardiac remodeling (elevated CTR) in patients on CHD. PMID:29261793

    This study was designed to evaluate the adherence of maintenance hemodialysis patients to medications and its correlation with quality of life and depressive symptoms. A total of 150 maintenance hemodialysis patients with a mean age of 56.4 ± 16.4 years (52.7% women) were included. Medication adherence was evaluated via the Simplified Medication Adherence Questionnaire, based on which nonadherent patients were identified. Specifically, the Drug-Intake Percentage Questionnaire was used for evaluation of adherence to phosphate binders, quality of life was assessed with short Form-36 and depression by the Beck Depression Inventory (BDI). A BDI score of 15 and greater was documented in 40.7%, and nonadherence in 24.7% of the patients. Adherent patients were significantly older than nonadherent ones, had a lower mean parathyroid hormone level, and had lower BDI scores. The quality of life scores were not significantly different between adherent and nonadherent patients. Multivariable analysis demonstrated that BDI score was a significant predictor of nonadherence (odds ratio for each unit increase, 1.11; 95% confidence interval, 1.04 to 1.18; P = .001). Overall, 55.5% of patients were taking more than 66% of their prescribed dose of calcium carbonate, while 10.3% and 53.8% of patients were taking more than 66% of their prescribed dose of aluminum hydroxide and sevelamer, respectively. Adherence to medication was mainly associated with hemodialysis patients' depressive symptom scores. Control of depression may significantly improve adherence to medications and patient management.

    Depression and anxiety have been considered as the most common comorbidities in maintenance hemodialysis (MHD) patients. This study aimed to assess mental disorder in hemodialysis patients and to study the indicators and correlates of psychological disturbance among patients receiving MHD in China. A cross-sectional study was conducted in 187 outpatients undergoing regular hemodialysis for at least 3 months. All the participants completed the Hospital Anxiety and Depression Scale (HADS), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue, Chinese mainland version), Pittsburgh Sleep Quality Index (PSQI), Family APGAR Index (PAGAR), Family Adaptability and Cohesion Evaluation Scale (FACES II, Chinese version) and the Social Functioning Questionnaire (SFQ). Based on the cutoff point of HADS-D/A ≥ 8, 51 (27.3%) and 29 (15.5%) patients reported depression and anxiety, respectively; 26 (13.9%) of all reported both depression and anxiety. Depressive patients had lower economic status, less subsidies, less than 3 years duration on hemodialysis and comorbidities when compared to patients without depression (all P < 0.05). HADS-D showed positive correlations with HADS-A, PSQI and SFQ and negative correlations with FACIT-Fatigue, PAGAR, family cohesion and adaptability (all P < 0.001). Patients with better family cohesion showed higher level of psychosocial well-being no matter their economic status. Binary logistic regression analysis demonstrated that anxiety (OR 1.80, P < 0.001) and bad social functioning (OR 1.31, P < 0.001) were independently associated with depression. More attention should be paid on assessment and management psychological disturbance, and development family/social/medical supporting system for Chinese patients receiving MHD.

    Routine serological testing for hepatitis C virus (HCV) infection among hemodialysis (HD) patients is currently recommended. A dilemma existed on the value of serology because some investigators reported a high rate of false-negative serologic testing. In this study, we aimed to detect the false-negative rate of anti-HCV among Egyptian HD patients. Seventy-eight HD patients, negative for anti-HCV, anti-HIV, and hepatitis B surface antigen, were tested for HCV RNA by reverse transcriptase polymerase chain reaction (RT-PCR). In the next step, the viral load was quantified by real-time PCR in RT-PCR-positive patients. Risk factors for HCV infection, as well as clinical and biochemical indicators of liver disease, were compared between false-negative and true-negative anti-HCV HD patients. The frequency of false-negative anti-HCV was 17.9%. Frequency of blood transfusion, duration of HD, dialysis at multiple centers, and diabetes mellitus were not identified as risk factors for HCV infection. The frequency of false-negative results had a linear relation to the prevalence of HCV infection in the HD units. Timely identification of HCV within dialysis units is needed in order to lower the risk of HCV spread within the HD units. The high false-negative rate of anti-HCV among HD patients in our study justifies testing of a large scale of patients for precious assessment of effectiveness of nucleic acid amplification technology testing in screening HD patient. © 2012 The Authors.

    Methotrexate (MTX) can be toxic to patients suffering from end stage renal disease (ESRD) on hemodialysis even at low doses. This increase in toxicity is more notable in terms of bone marrow suppression in the form of pancytopenia. Many methods of elimination including dialysis itself have been proven ineffective, and alternate treatments with anti-TNF alpha blockers can be considered.

    Objective To compare outcomes between elderly (≥65 years old) and non-elderly (<65 years old) resuscitated severe sepsis and septic shock patients and determine predictors of death among elderly patients. Methods Retrospective cohort study including 848 severe sepsis and septic shock patients admitted to the intensive care unit between January 2006 and March 2012. Results Elderly patients accounted for 62.6% (531/848) and non-elderly patients for 37.4% (317/848). Elderly patients had a higher APACHE II score [22 (18-28) versus 19 (15-24); p<0.001], compared to non-elderly patients, although the number of organ dysfunctions did not differ between the groups. No significant differences were found in 28-day and in-hospital mortality rates between elderly and non-elderly patients. The length of hospital stay was higher in elderly compared to non-elderly patients admitted with severe sepsis and septic shock [18 (10-41) versus 14 (8-29) days, respectively; p=0.0001]. Predictors of death among elderly patients included age, site of diagnosis, APACHE II score, need for mechanical ventilation and vasopressors. Conclusion In this study population early resuscitation of elderly patients was not associated with increased in-hospital mortality. Prospective studies addressing the long-term impact on functional status and quality of life are necessary. PMID:26313436

    Background Patients with end-stage renal disease on hemodialysis have excess cardiovascular disease (CVD) burden with substantially increased CV event rates compared with the general population. Summary Traditional interventions that, according to standard clinical guidelines, reduce CV risk such as antihypertensive therapy, diet, exercise, and statins are not similarly effective in the hemodialysis population. This raises the question of whether additional risk factors, such as enhanced inflammation and oxidative stress, may drive the increased CVD burden in hemodialysis patients. Eicosapentaenoic acid (EPA), an omega-3 polyunsaturated fatty acid, is incorporated into the atherosclerotic plaque as well as membrane phospholipid bilayers and produces beneficial effects on inflammatory and oxidative mechanisms involved in atherosclerotic plaque formation and progression. EPA levels and the ratio of EPA to the omega-6 polyunsaturated fatty acid arachidonic acid (AA) are reduced in hemodialysis patients. Serum EPA levels have been inversely correlated with proinflammatory cytokines, and the EPA/AA ratio has been inversely associated with CV events in hemodialysis cohorts. Three recent studies involving over 800 hemodialysis patients and follow-up of 2–3 years suggest that EPA therapy may improve clinical outcomes in this patient population as evidenced by significant reductions in cardiovascular mortality, all-cause mortality, and/or CV events. Key Messages Further studies with high-purity EPA are warranted in patients on hemodialysis, especially given the fact that other interventions including antihypertensives, diet, exercise, and statins have not provided meaningful benefit.

    The whole-body 2-deoxy-2-[(18)F]fluoro-D-glucose (FDG) distribution in chronic renal failure (CRF) patients on hemodialysis would be different from that in subjects with normal renal function, because they lack urinary FDG excretion and remain in a constant volume overload. We evaluated the difference in the physiological uptake pattern of FDG between chronic renal failure patients on hemodialysis and control subjects. The subjects for this retrospective study consisted of 24 chronic renal failure patients on hemodialysis (HD group) and 24 age- and sex-matched control subjects (NC group). Standardized uptake values normalized by the body weight (SUVbw), ideal body weight (SUVibw), lean body mass (SUVlbm), and body surface area (SUVbsa) in the cerebellum, lungs, liver, gluteal muscles and subcutaneous fat, spleen, thoracolumbar spine, thoracic and abdominal aorta, and right atrium were calculated in positron emission tomography/computed tomography (PET/CT) images. SUVbw in the gluteal muscles, subcutaneous fat, spleen and right atrium was significantly higher in the HD group as compared to that in the NC group (p < 0.05; unpaired t test). In addition, SUVibm, SUVlbm, as well as SUVbsa in the abdominal aorta were significantly higher in the HD group as compared to those in the NC group (p < 0.05; unpaired t test). In conclusion, as compared to normal subjects, chronic renal failure patients on hemodialysis show significantly higher physiological FDG uptake in the soft tissues, spleen and blood pool.

    Hemodialysis patients possess particular attributes which increase the susceptibility to hepatitis B virus (HBV) infections. HBV vaccination significantly decreased the number of new HBV-infected patients. However, the conventional vaccination schedule requires a 6-months duration. This study aimed to examine the efficacy the accelerated vaccination schedule among hemodialysis patients. In this study, 202 consecutive hemodialysis patients at New Jeddah hospital were enrolled. The inclusion criteria were: (1) age was above 18 years, (2) all patients had undetectable HBV surface antigen and antibody. Exclusion criteria included: (1) patient had a positive serum HBV surface antigen and antibody using enzyme-linked immunosorbent assay; (2) patient received a previous course of HBV vaccine, (3) patient who was pregnant. Patients were sequentially randomized to receive either Hepatitis B recombinant DNA vaccine (conventional schedule) or to receive combined hepatitis A and B vaccine injection (accelerated schedule). Testing for HBV surface antibodies was done one and three months after completion of the dosage schedule. The primary outcome was the proportion of seroprotection (defined by serum HBV surface antibodies ≥ 10 mIU/ml). Adverse reactions were evaluated regarding both fever and post-injection pain scale. Patients' age ranged from 18 to 71 years.After 1 and 3 months of completion of the vaccination schedule, there was no statistical difference in the proportion of seroprotected patients among both groups. Accelerated vaccination schedule using combined hepatitis A and B vaccine may be beneficial for HBV seroprotection among hemodialysis patients.

    The stress of living with a terminal disease has a negative impact on the mental health of hemodialysis (HD) patients. Spirituality is a potential coping mechanism for stressful experiences. Studies on the relationship between spirituality and mental health among HD patients are scarce. The purpose of this study was to evaluate the relationship between mental health and spiritual well-being among HD patients. Cross-sectional observational study on hemodialysis patients at a single center in Brazil, between January and December 2011. Mental health was assessed using the General Health Questionnaire and spiritual wellbeing was assessed using the Spiritual Wellbeing Scale; 150 HD patients participated in the study. A significant correlation was found between mental health and spiritual wellbeing (P = 0.001). Spiritual wellbeing was the strongest predictor of mental health, psychological distress, sleep disturbance and psychosomatic complaints. Poor mental health was associated with lower spiritual wellbeing. This has important implications for delivery of palliative care to HD patients.

    Patients treated with hemodialysis develop severely reduced functional capacity, which can be partially ameliorated by correcting anemia and through exercise training. In this study, we determined perturbations of an erythroid-stimulating agent and exercise training to examine if and where limitation to oxygen transport exists in patients on hemodialysis. Twenty-seven patients on hemodialysis completed a crossover study consisting of two exercise training phases at two hematocrit (Hct) values: 30% (anemic) and 42% (physiologic; normalized by treatment with erythroid-stimulating agent). To determine primary outcome measures of peak power and oxygen consumption (VO2) and secondary measures related to components of oxygen transport and utilization, all patients underwent numerous tests at five time points: baseline, untrained at Hct of 30%, after training at Hct of 30%, untrained at Hct of 42%, and after training at Hct of 42%. Hct normalization, exercise training, or the combination thereof significantly improved peak power and VO2 relative to values in the untrained anemic phase. Hct normalization increased peak arterial oxygen and arteriovenous oxygen difference, whereas exercise training improved cardiac output, citrate synthase activity, and peak tissue diffusing capacity. However, although the increase in arterial oxygen observed in the combination phase reached a value similar to that in healthy sedentary controls, the increase in peak arteriovenous oxygen difference did not. Muscle biopsy specimens showed markedly thickened endothelium and electron–dense interstitial deposits. In conclusion, exercise and Hct normalization had positive effects but failed to normalize exercise capacity in patients on hemodialysis. This effect may be caused by abnormalities identified within skeletal muscle. PMID:27153927

    Outpatients undergoing hemodialysis are at high risk for adverse drug events. Limited resources make it challenging for pharmacists to routinely obtain a best possible medication history (BPMH). The primary objective was to determine whether, for patients undergoing hemodialysis, a pharmacy technician has the skills to obtain a BPMH that would allow a pharmacist to identify drug-related problems. The secondary objectives were to determine the number and types of medication discrepancies and drug-related problems identified and the time required by the technician to complete the BPMH. All patients treated in the hemodialysis unit during the study period were included, except for those who required an interpreter or were unable to participate in an in-person interview. A single technician was taught how to interview patients according to a structured format. For each patient, the technician's BMPH was verified by a pharmacist. The agreement rate between technician and pharmacists was determined, along with the number and types of discrepancies and drug-related problems identified. The technician interviewed 99 patients. Of the 1334 medication orders reviewed, the technician and pharmacists agreed on all but 15 (agreement rate 98.9%). A total of 358 medication discrepancies were noted for 93 patients (3.8 discrepancies per patient). Of these, 210 (59%) were undocumented intentional discrepancies, and 148 (41%) were unintentional discrepancies (most commonly errors of commission). Of the 135 drug-related problems identified, the majority involved dosing problems or nonadherence. The technician required an average of 17 min for each interview. An adequately trained technician was capable of interviewing patients to create a BPMH. A variety of medication discrepancies and drug-related problems were identified. Generation of a BPMH by a technician is a useful approach allowing pharmacists to identify drug-related problems.

Here, we compare patient and treatment survival for patients receiving short daily HHD (2-3 hours/5 plus sessions per week), nocturnal HHD (6-8 hours/5 plus sessions per week) and conventional HHD (3-6 hours/2-4 sessions per week). A nationally representative cohort of Canadian HHD patients from 1996-2012 was studied. The primary outcome was death or treatment failure (defined as a permanent return to in-center hemodialysis or peritoneal dialysis) using an intention to treat analysis and death-censored treatment failure as a secondary outcome. The cohort consisted of 600, 508 and 202 patients receiving conventional, nocturnal, and short daily HHD, respectively. Conventional-HHD patients were more likely to use dialysis catheter access (43%) versus nocturnal or short daily HHD (32% and 31%, respectively). Although point estimates were in favor of both therapies, after multivariable adjustment for patient and center factors, there was no statistically significant reduction in the relative hazard for the death/treatment failure composite comparing nocturnal to conventional HHD (hazard ratio 0.83 [95% confidence interval 0.66-1.03]) or short daily to conventional HHD (0.84, 0.63-1.12). Among those with information on vascular access, patients receiving nocturnal HHD had a relative improvement in death-censored treatment survival (0.75, 0.57-0.98). Thus, in this national cohort of HHD patients, those receiving short daily and nocturnal HHD had similar patient/treatment survival compared with patients receiving conventional HHD.

    Patient engagement and patient-centered care are critical in optimally managing patients with end-stage renal disease (ESRD). Understanding patient preferences is a key element of patient-centered care and shared decision making. The objective of this study was to elicit patients' preferences for the treatment of secondary hyperparathyroidism (SHPT) associated with ESRD using a discrete-choice experiment survey. Clinical literature, nephrologist input, patient-education resources, and a patient focus group informed development of the survey instrument, which was qualitatively pretested before its administration to a broader sample of patients. The National Kidney Foundation invited individuals in the United States with ESRD who were undergoing hemodialysis to participate in the survey. Respondents chose among three hypothetical SHPT treatment alternatives (two medical alternatives and surgery) in each of a series of questions, which were defined by attributes of efficacy (effect on laboratory values and symptoms), safety, tolerability, mode of administration, and cost. The survey instrument included a best-worst scaling exercise to quantify the relative bother of the individual attributes of surgery. Random-parameters logit models were used to evaluate the conditional relative importance of the attributes. A total of 200 patients with ESRD completed the survey. The treatment attributes that were most important to the respondents were whether a treatment was a medication or surgery and out-of-pocket cost. Patients had statistically significant preferences for efficacy attributes related to symptom management and laboratory values, but placed less importance on the attributes related to mode of administration and side effects. The most bothersome attribute of surgery was the risk of surgical mortality. Patients with ESRD and SHPT who are undergoing hemodialysis understand SHPT and have clear and measurable treatment preferences. These results may help inform

    Introduction: Patient's noncompliance dietary and fluids intake can lead to a build-up of toxic fluids and metabolic end-products in the blood stream which may result in an increased morbidity and premature death. The aim of the study is investigate relationship between the social support and adherence to dietary and fluid restrictions in hemodialysis patients. Methods: In this correlational study upon 237 hemodialysis patients, the data was collected with the dialysis diet and fluids non-adherences hemodialysis questionnaire (DDFQ), and the multidimensional scale of perceived Social Support (MSP). Interdialytic weight gain, predialytic serum potassium levels, and predialytic serum phosphate levels was considered as biochemical indicators of dietary and fluid adherence. Data were analyzed by SPSS Ver.11.5. Results: About 41.1% of patients reported non-adherence to diet and 45.2% of them reported non-adherence to fluid. Frequency of non-adherence to fluid was more common in patients. The highest level of perceived support was the family support 11.19 (1.34). There was a significant relationship between social support and adherence to dietary and fluid restrictions. Noncompliances to dietary and fluid restrictions were related to laboratory results. Conclusion: This way those patients who more supported had more adherences of diet and fluid restrictions and had lower level of phosphorus and potassium in laboratory results. Nurses have the main role to identify different methods providing social support for patients, also to encourage the families to support their hemodialysis patients. PMID:25276744

    Dietary sodium is thought to play a major role in the pathogenesis of hypertension, hypervolemia, and mortality in hemodialysis patients; hence, sodium restriction is almost universally recommended. Since the evidence upon which to base these assumptions is limited, we undertook a post-hoc analysis of 1770 patients in the Hemodialysis Study with available dietary, clinical, and laboratory information. Within this cohort, 772 were men, 1113 black, and 786 diabetic, with a mean age of 58 years and a median dietary sodium intake of 2080 mg/day. After case-mix adjustment, linear regression modeling found that higher dietary sodium was associated with a greater ultrafiltration requirement, caloric and protein intake; sodium to calorie intake ratio was associated with a greater ultrafiltration requirement; and sodium to potassium ratio was associated with higher serum sodium. No indices were associated with the pre-dialysis systolic blood pressure. Cox regression modeling found that higher baseline dietary sodium and the ratio of sodium to calorie or potassium were each independently associated with greater all-cause mortality. No association between a prescribed dietary sodium restriction and mortality were found. Thus, higher reported dietary sodium intake is independently associated with greater mortality among prevalent hemodialysis patients. Randomized trials will be necessary to determine whether dietary sodium restriction improves survival.

    Coffee drinking is the main source of caffeine intake among adult population in the western world. It has been reported that low to moderate caffeine intake has beneficial effect on alertness and cognitive functions in healthy subjects. The aim of this study is to evaluate the impact of habitual coffee consumption on cognitive function in hemodialysis patients. In a cross-sectional study, 86 patients from a single-dialysis centre underwent assessment by the Montreal Cognitive Assessment tool and evaluation for symptoms of fatigue, mood, and sleep disorders by well-validated questionnaires. The habitual coffee use and the average daily caffeine intake were estimated by participants' response to a dietary questionnaire. Sixty-seven subjects (78%) consumed black coffee daily, mostly in low to moderate dose. Cognitive impairment was found in three-quarters of tested patients. Normal mental performance was more often in habitual coffee users (25% versus 16%). Regular coffee drinkers achieved higher mean scores on all tested cognitive domains, but a significant positive correlation was found only for items that measure attention and concentration (P = 0.024). Moderate caffeine intake by habitual coffee consumption could have beneficial impact on cognitive function in hemodialysis patients due to selective enhancement of attention and vigilance.

    This study was undertaken to describe the relationship between hematocrit (Hct) and changes in the prescribed dose of erythropoietin (EPO) as well as selected patient and process care measures across annual national samples of hemodialysis patients from 1994 to 1998. This study uses the cohorts identified in the ESRD Core Indicators Project, random samples of 6181, 6241, 6364, 6634, and 7660 patients, stratified by ESRD Networks drawn for each year from 1994 to 1998. Patient demographic and clinical information was collected from October to December for each year. Surrogates of iron stores and patterns of iron and EPO administration were profiled from 1996 to 1998. Multivariable stepwise linear regression analyses were performed to adjust for potential confounding variables and to identify independent variables associated with Hct and EPO dose. Mean Hct and EPO dose increased each year from 31.1 +/- 5.2% to 34.1 +/- 3.7% and from 58.2 +/- 41.8 U/kg to 68.2 +/- 55.0 U/kg, respectively (P = 0.0001). Increasing Hct was positively associated with male gender, more years on dialysis, older age, higher urea reduction ratio and transferrin saturation, prescription of intravenous iron, and lower ferritin and EPO dose in multivariable models (all P = 0.0001). Male gender, older age, diabetes, higher Hct, and increasing weight, urea reduction ration, and transferrin saturation were associated with lower EPO doses (all P < 0.01). Conversely, intravenous EPO and iron were associated with higher prescribed EPO doses (all P = 0.0001). Although increasing Hct is associated with decreasing EPO dose at the patient level, the increase in Hct seen across years among the cohorts of hemodialysis patients in the United States has been associated with increasing doses of EPO at the population level.

    Chronic hemodialysis is implemented when irreversible loss of kidney function occurs. Sometimes renal recovery is overlooked. From January 2005 to December 2014, we identified 28 patients hemodialyzed for more than 3 months who had renal replacement therapy discontinued. The group consisted of 17 (57.7%) males and 11 (42.3%) females. Patients were 18-87 years old. Time of hemodialysis ranged from 3 to 97 months. Of note, 14 (50%) patients were referred from local dialysis units for solution of vascular access problems. In 13 (46.2%) patients dialysis was abandoned within the first 6 months, in 5 (17.8%) patients between 6 and 12 months, and in 10 (35.7%) patients beyond 12 months. Estimated dialysis-free survival was 94.4% (SE 0.054) and 82% (SE 0.095) at 12 and 24 months, respectively. All physicians must be aware of possible kidney function improvement. In patients with preserved diuresis fall in periodical urea or creatinine measurements might be a sign of renal recovery. © 2015 International Society for Hemodialysis.

    Background: Today, despite remarkable advances in the care of hemodialysis patients, the quality of life (QOL) for these patients is still unsatisfactory. Although previous reports confirmed the effect of exercise on the well-being of renal patients, less than 50% of end-stage kidney patients participate in a regular sports program. Tai chi is a slow and gentle exercise that is suitable for people with chronic illnesses and those with severe intolerance of exercise. Therefore, this study aimed to determine the effect of tai chi exercise on the QOL of hemodialysis patients. Materials and Methods: This was a quasi-experimental study conducted in a single group and in two steps. Twenty-five hemodialysis patients, admitted to hospitals in Isfahan, Iran, were selected, and their QOL was compared before and after intervention in two domains of satisfaction and importance. Convenience sampling was used. The sampling was convenience. The subjects were trained in the intervention through a single session of tai chi exercise class for one hour weekly, for 12 weeks, with a training compact disc (CD) that helped the patients to exercise at least twice a week at home. Data were collected by the completion of a demographic characteristics form and a researcher-made QOL questionnaire adopted from Ferrans and Powers Quality of Life Index Dialysis Version and the Kidney Disease Quality of Life-Short Form (KDQOL-SF) questionnaire by the researchers. The data were analyzed by a paired t-test through SPSS software version 18. Results: Data analysis showed that there was a statistically significant difference in health and functioning (P < 0.001), socioeconomic (P < 0.001), and psychospiritual (P < 0.001) dimensions, and the family dimension had P = 0.002 in the satisfaction domain and P = 0.008 in the importance domain; the total score of quality of life in both domains was P < 0.001. Conclusions: According to the research findings, tai chi exercise improves the QOL score

    Over the past two decades, healthcare-associated exposure has increasingly been proved to be a means of hepatitis C virus (HCV) transmission, especially in hemodialysis facilities. The prevalence of HCV among hemodialysis patients is known to be several times greater than that of the general population of the United States, and chronic HCV infection is associated with significant morbidity and mortality among these patients. During 2008-2011, HCV infection outbreaks were identified in multiple US hemodialysis facilities, resulting in at least 46 new HCV infections among hemodialysis patients. These outbreaks, linked to infection control breaches, also highlight the failure of some facilities to follow established guidelines for routine HCV antibody (anti-HCV) screening and response to new HCV infection among hemodialysis patients. Current national guidelines recommend screening of hemodialysis patients for anti-HCV on facility admission and, for susceptible patients, on a semiannual basis. Here, we seek to underscore the importance of compliance with national recommendations for anti-HCV screening of hemodialysis patients and actions to be taken in the event of possible HCV transmission within a hemodialysis facility. These include general steps to ensure that: hemodialysis patients are routinely screened for anti-HCV to facilitate early detection of new infections; newly infected patients are informed of the change in their HCV status and undergo clinical evaluation; and public health officials are notified of new HCV infections in a timely manner. We then focus on the need to assess infection control practices at the facility, with particular attention given to safe handling of injectable medications, hand hygiene and disinfection practices. In the absence of a vaccine, routine screening and adherence to standard infection control practices will remain the key strategies for preventing HCV transmission in hemodialysis units.

    Patients with end-stage renal disease (ESRD) have increased risk of falls and fall-related complications. Other than aging and factors related to chronic kidney disease, treatment of hemodialysis may also contribute to this increased risk. The aim of this study was to demonstrate the impairment of balance after a session of hemodialysis with a quantitative assessment and reveal an increased fall risk that would possibly be related to treatment of hemodialysis for patients on maintenance hemodialysis. Fifty-six patients with ESRD on chronic hemodialysis program and 53 healthy individuals were involved in this study. Fall Index percentages were calculated, and fall risk categories were determined for all patients and healthy controls using Tetrax posturography device (Sunlight Medical Ltd Israel). The patient group was evaluated twice for balance, before and after a routine session of hemodialysis. Fall Index scores of healthy controls were lower than that of ESRD patients (p = 0.001). In the patient group, we found the mean Fall Index to be significantly higher at the post-dialysis assessment compared to the pre-dialysis assessment (p = 0.003). The number of patients with high risk of falling also increased at the post-dialysis assessment yet the difference did not reach significance. Fall Index was correlated with the increase in age only at the pre-dialysis balance measurement (p = 0.038). Patients with better dialysis adequacy had significantly lower Fall Index scores than the others at the pre-dialysis balance measurement (p = 0.004). The difference was not significant at the post-dialysis measurement. In the current study, we evaluated the balance of ESRD patients before and after a routine session of hemodialysis treatment. This is the first study to investigate the effect of hemodialysis on balance, using an electronic posturographic balance system. We found the Fall Index score to be significantly higher after hemodialysis, indicating a negative

    Purpose: The purpose of this article was to share midterm results of percutaneous cholecystostomy (PC) as a first-line therapy in chronic hemodialysis patients with acute cholecystitis. Methods: Fourteen chronic hemodialysis patients with acute cholecystitis underwent PC between March 2007 and May 2009 at our institute. On preoperative assessment, the patients were classified into the ASA score by the anesthesiology team. All patients were class IV because of severe underlying comorbidities. The patients were referred to interventional radiology unit for PC by consensus of the multidisciplinary team. Results: The PC was technically successful in all the patients without minor or majormore » complications related to the procedure. Clinical symptoms in three patients who presented with sepsis and multiorgan failure did not resolve after PC, and these patients died following urgent surgery, including open cholecystectomy and common bile duct exploration. A new cholecystitis attack was detected in one patient in the acalculous group at the sixth month of the follow-up period. The mean catheterization time was 31.7 (range, 28-41) days. The mean follow-up time was 13.3 (range 4-21) months. Conclusions: The PC may come into consideration as a first-line treatment modality in the management of acute cholecystitis in poor surgical candidate chronic hemodialysis patients. This is the first report focusing on the midterm results of PC as a first-line therapy in hemodialysis patients with acute cholecystitis who could be operated on.« less

    Uremic pruritus (UP) is an unpleasant complication in patients undergoing maintenance dialysis. Cardiovascular and infection related deaths are the major causes of mortality in patients undergoing dialysis. Studies on the correlation between cardiovascular or infection related mortality and UP are limited. We analyze 866 maintenance hemodialysis (MHD) patients in our hemodialysis centers. Clinical parameters and 24-month cardiovascular and infection-related mortality are recorded. The associations between all-cause, cardiovascular and infection related mortality with clinical data including UP are analyzed. Multivariate Cox regression demonstrated that UP is a significantly predictor for 24-month cardiovascular mortality in the MHD patients (Hazard ratio: 3.164; 95% confidence interval, 1.743-5.744; p < 0.001). Uremic pruritus is one of the predictor of 24-month cardiovascular mortality in MHD patients. © 2018 The Author(s). Published by S. Karger AG, Basel.

    To compare the epidemiologic profiles of hepatitis A virus (HAV) and hepatitis E virus (HEV) infections in Japan, the prevalence of clinical or subclinical HAV and HEV infections was investigated serologically and molecularly among 128 consecutive patients (age, mean +/- standard deviation, 37.5 +/- 14.7 years) who contracted acute hepatitis between 1989 and 2005 in a city hospital, and among 416 hemodialysis patients (60.1 +/- 12.6 years) and 266 medical staff members (34.6 +/- 11.4 years) at the same hospital, using stored periodic serum samples collected since the start of hemodialysis or employment, respectively. Between 1989 and 1995, among 93 patients with acute hepatitis, 51 (54.8%) were diagnosed with hepatitis A and only one patient with hepatitis E. Between 1996 and 2005, however, among 35 patients, only 3 (8.6%) were diagnosed with hepatitis A and 2 (5.7%) with hepatitis E. Although subclinical HEV infection was recognized in four hemodialysis patients (one each in 1979, 1980, 1988, and 2003) and two medical staff members (1978 and 2003) in previous studies, none of the 191 hemodialysis patients who had been negative for anti-HAV at the start of hemodialysis contracted HAV infection during the observation period of 7.6 +/- 6.4 years. Only one (0.4%) of the 246 medical staff members who had been negative for anti-HAV at the start of employment acquired hepatitis A during the observation period of 7.9 +/- 8.0 years: none had subclinical HAV infection. Clinical or subclinical HEV infection has occurred rarely during the last three decades, while HAV infection has markedly decreased at least since 1996. 2006 Wiley-Liss, Inc.

    Clinical outcomes after a hospital discharge are poorly defined for patients receiving maintenance in-center (outpatient) hemodialysis. To describe the proportion and characteristics of these patients who are rehospitalized, visit an emergency department, or die within 30 days after discharge from an acute hospitalization, we conducted a population-based study of all adult patients receiving maintenance in-center hemodialysis who were discharged between January 1, 2003, and December 31, 2011, from 157 acute care hospitals in Ontario, Canada. For patients with more than one hospitalization, we randomly selected a single hospitalization as the index hospitalization. Of the 11,177 patients included in the final cohort, 1926 (17%) were rehospitalized, 2971 (27%) were treated in the emergency department, and 840 (7.5%) died within 30 days of discharge. Complications of type 2 diabetes mellitus were the most common reason for rehospitalization, whereas heart failure was the most common reason for an emergency department visit. In multivariable analysis using a cause-specific Cox proportional hazards model, the following characteristics were associated with 30-day rehospitalization: older age, the number of hospital admissions in the preceding 6 months, the number of emergency department visits in the preceding 6 months, higher Charlson comorbidity index score, and the receipt of mechanical ventilation during the index hospitalization. Thus, a large proportion of patients receiving maintenance in-center hemodialysis will be readmitted or visit an emergency room within 30 days of an acute hospitalization. A focus on improving care transitions from the inpatient setting to the outpatient dialysis unit may improve outcomes and reduce healthcare costs. PMID:25855772

    Background: Poor adherence to treatment in patients undergoing hemodialysis leads to many complications, including death of the patient. Objectives: This study was aimed to investigate the effect of family-based training on common side-effects during dialysis. Patients and Methods: The present randomized controlled trial study was conducted on 60 patients undergoing hemodialysis at hospitals of Tehran University of Medical Sciences, Iran, from May 2012 to October 2012. Samples were randomly divided into two groups of patient-education (n = 30) and education of patient associated with an active member of the family (n = 30). Blood pressure, chest pain, nausea, vomiting, headaches and muscle cramps were followed with a check list and a questionnaire. The frequencies of the abovementioned complications at the mentioned intervals were recorded in three stages (before the intervention as well as two and four weeks after the intervention). Data analysis was performed using SPSS software, version 16, with chi-square test, Fisher’s exact test and independent t-test. Results: The mean ages of the patients in patient-centered and the family-oriented groups were 47.41 ± 10.31 and 48.16 ± 9.21, respectively. The result showed that some of the variables such as chest pain (P = 0.50, P = 0.01), nausea (P = 0.50, P = 0.01), headache (P = 0.81, P = 0.016), and blood pressure (P = 0.91, P = 0.016) were statistically significant before and four weeks after the intervention. Conclusions: According to the result of this study, the presence of families in a treatment plan could be essential to follow the treatment plan and subsequently reduced the complications of hemodialysis.

    Intestinal parasites are an important cause of morbidity and mortality. Immunocompromised individuals may develop more severe forms of these infections. Taking into account the immunity impairment in patients suffering from chronic renal failure (CRF), we will determine the prevalence and associated symptoms of intestinal parasites in these patients. Controls without CRF were used for comparison. Stool samples were collected and processed for microscopic identification of parasites using the Formalin-ether concentration method. For Cryptosporidium diagnosis, the ELISA technique was used. One hundred and ten fecal samples from hemodialysis patients were analyzed, as well as 86 from a community group used as control group. A result of 51.6% of intestinal parasites was observed in hemodialysis patients and 61.6% in the control group. Cryptosporidium and Blastocystis were the most common infections in patients with CRF (26.4% and 24.5%, respectively). Blastocystis was the most common infection in the control group (41.9%), however no individual was found positive for Cryptosporidium. Among the CRF patients, 73.6% were symptomatic, 54.3% of these tested positive for at least one parasite, in contrast to 44.8% in asymptomatic patients (p = 0.38). The most common symptoms in this group were flatulence (36.4%), asthenia (30.0%) and weight loss (30.0%). In the control group, 91.9% were symptomatic, 60.8% of these tested positive for at least one parasite, in contrast to 71.4% in asymptomatic patients (p = 0.703). A significant difference between the two groups was observed with regard to symptoms, with bloating, postprandial fullness, and abdominal pain being more frequent in the control group than in the hemodialysis group (all p < 0.05). Comparing symptomatic with asymptomatic, there was no association in either group between symptoms or the prevalence of parasitic infection, nor with the type of parasite or with multiple parasitic infections.

    The synovial fluid components in long-term hemodialysis patients (HD; 43 knees in 43 patients) were investigated and compared with those in patients with osteoarthritis (OA; 21 knees in 21 patients) and rheumatoid arthritis (RA; 26 knees in 26 patients). The average ages in the three groups were, respectively, 60.7 years (range, 34-79 years), 63.2 years (range, 48-88 years), and 59.7 years (range, 37-76 years). The duration of hemodialysis in the HD group averaged 14.0 years (range, 4-24 years). The concentrations of hyaluronic acid, protein, and isomers of chondroitin sulfate (chondroitin 6-sulfate [C6S] and chondroitin 4-sulfate [C4S]) in the synovial fluid, and its viscosity were measured. Differences in each of the parameters were investigated according to disease clinical stage, roentgenological grade, and periods of dialysis in the HD group. The viscosity of the synovial fluid and the concentration of hyaluronic acid in HD patients were similar to those in OA patients; however, the C6S/C4S ratio in the synovial fluid of HD patients was similar to that in RA patients. The latter finding suggests that synovitis may be present in the hydrarthrosis of HD patients. The cause of this synovitis in HD patients remains to be elucidated.

    Report 11 years of experience with self-managed hemodialysis in patients medically apt for extra-hospital dialysis and living close enough to small outpatient hemodialysis units to become totally self-sufficient. Among the 276 patients with chronic renal failure managed at the hemodialysis center at the Troyes hospital during the 11-year study period from 1984 through 1994, self-managed hemodialysis at small outpatient units was initiated in 127 (46%). None of these 127 patients required medical assistance or specific care during dialysis sessions. At initial hospital admission, only 60/127 (47%) were totally self-sufficient: 52 (41%) were later graft recipients; and 21 (16.5%) had to return to the hospital for a medical or surgical condition incompatible with extra-hospital care but all of these 21 patients remained self-sufficient. Extra-hospital hemodialysis in units close to the patients residence offers patients a better quality of life, even when medical assistance is required. All patients who require hemodialysis can thus be treated at lower cost without compromising quality of treatment. Perfect self-sufficiency may not be a goal in itself, but self-managed hemodialysis can be a very useful technique for patients without major medical problems. Continuing contact with the organizing hemodialysis center guarantees the safety of the system.

  16. Elderly patients and inflammatory bowel disease

    The incidence and prevalence of inflammatory bowel disease (IBD) is increasing globally. Coupled with an ageing population, the number of older patients with IBD is set to increase. The clinical features and therapeutic options in young and elderly patients are comparable but there are some significant differences. The wide differential diagnosis of IBD in elderly patients may result in a delay in diagnosis. The relative dearth of data specific to elderly IBD patients often resulting from their exclusion from pivotal clinical trials and the lack of consensus guidelines have made clinical decisions somewhat challenging. In addition, age specific concerns such as co-morbidity; loco-motor and cognitive function, poly-pharmacy and its consequences need to be taken into account. In applying modern treatment paradigms to the elderly, the clinician must consider the potential for more pronounced adverse effects in this vulnerable group and set appropriate boundaries maximising benefit and minimising harm. Meanwhile, clinicians need to make personalised decisions but as evidence based as possible in the holistic, considered and optimal management of IBD in elderly patients. In this review we will cover the clinical features and therapeutic options of IBD in the elderly; as well as addressing common questions and challenges posed by its management. PMID:26855812

    Gefitinib is highly active in patients with advanced or metastatic non-small cell lung cancer (NSCLC) harboring activating mutation of the epidermal growth factor receptor (EGFR) gene. The feasibility and the degree of response to treatment with gefitinib in patients with chronic renal failure (CRF) undergoing hemodialysis has not yet been fully described in literature. We describe the case of a 70-year-old man with CRF undergoing hemodialysis three times-a-week who developed vertebral and rib bone metastasis three years after lobectomy. The bone biopsy confirmed the pulmonary origin and pyrosequencing analysis revealed deletion in E746-E750 of exon 19. We started daily administration of 250 mg gefitinib with no changes in the hemodialysis schedule. Gefitinib was well-tolerated without any adverse event. After three months, the (18)F-fluoro-2-deoxy-d-glucose positron emission tomography/computed tomography (FDG PET/CT) showed complete metabolic remission of bone lesions. The patient is still under treatment and maintains response (30 months to date). To our knowledge, this is the first description of complete metabolic remission in this type of patient. In conclusion, gefitinib has been safely administered to a patient with NSCLC with EGFR-activating mutation undergoing chronic hemodialysis and its use has achieved an excellent and prolonged response on bone metastases.

    The ratio between plasma kynurenine (Kyn) and tryptophan (Trp) serves as a marker of indoleamine 2,3-dioxygenase, a critical immunomodulatory molecule. Simultaneous detection of the two markers may be performed using high-pressure liquid chromatography (HPLC). However, for uremic patients, the conventional detection method may be affected by a range of accumulated toxins. The current study aimed to establish a method for the simultaneous measurement of Kyn and Trp in patients following maintenance hemodialysis via HPLC-ultraviolet detection. The procedure involved the use of a SinoChrom ODS-BP C18 column (4.6×150 mm; inner diameter, 4.5 μm) and a mobile phase of 15 mmol/l sodium acetate acetic acid solution (containing 5% acetonitrile, pH 4.8). The modified method was verified using plasma samples from 10 healthy controls and 91 maintenance hemodialysis patients. The results demonstrated that the modified method was successful in simultaneously detecting the concentrations of Trp and Kyn in the healthy controls and maintenance hemodialysis patients. The method is simple, fast, accurate and suitable for clinical and research purposes in maintenance hemodialysis patients. PMID:24669249

    Background: Hemodialysis patients are at an increased risk of polypharmacy as they have the highest pill burden of all chronically ill patient populations, with an estimated average of 12 medications per day. Objectives: The aim of this study was to evaluate prescribing patterns of outpatient medications in patients receiving in-center hemodialysis. This was done to identify potential candidate medications for future quality improvement initiations to optimize prescribing. Design: We conducted a descriptive retrospective cross-sectional study in the province of Ontario, Canada, using several linked health care databases housed at the Institute for Clinical Evaluative Sciences (ICES). Setting: We considered outpatient medications dispensed to patients eligible for the Ontario Drug Benefit program. Patients: Patients were receiving chronic in-center hemodialysis at one of the 69 facilities in the province of Ontario, Canada as of October 1, 2013. Measurements: We assessed whether any of our 28 study medications of interest were recently dispensed (within the prior 120 days), the type of prescribing physician, and the associated medication costs. The 28 included medications of interest (ie, proton pump inhibitors, benzodiazepines) were selected because they may not have a true indication for dialysis patients and/or there are safety concerns with their use in this population. Results are presented as median (25th, 75th percentile). Methods: We conducted this study at ICES according to a prespecified protocol approved by the Research Ethics Board at Sunnybrook Health Sciences Centre (Toronto, Ontario). Results: A total of 3094 patients on chronic in-center hemodialysis received a study drug of interest (age: 76.5 years [SD: 7.3]), 44% women). Patients were dispensed 11 (8, 14) unique medication products with more than two-thirds of patients dispensed 9 or more different medications.

    In the developed world, the large birth cohorts of the so-called baby boomer generation have arrived in medical and dental practices. Often, elderly patients are 'young-old' baby boomers in whom partial edentulism is the predominant indication for implant therapy. However, the generation 85+ years of age represents a new challenge for the dental profession, as their lives are frequently dominated by dependency, multimorbidity and frailty. In geriatric implant dentistry, treatment planning is highly individualized, as interindividual differences become more pronounced with age. Nevertheless, there are four typical indications for implant therapy: (i) avoidance of removable partial prostheses; (ii) preservation of existing removable partial prostheses; (iii) stabilization of Kennedy Class I removable partial prostheses; and (iv) stabilization of complete prostheses. From a surgical point of view, two very important aspects must be considered when planning implant surgery in elderly patients: first, the consistent strive to minimize morbidity; and, second, the fact that coexisting medical risk factors are significantly more common in elderly patients. Modern three-dimensional cone beam computed tomography imaging is often indicated in order to plan minimally invasive implant surgery. Computer-assisted implant surgery might allow flapless implant surgery, which offers a low level of postoperative morbidity and a minimal risk of postsurgical bleeding. Short and reduced-diameter implants are now utilized much more often than a decade ago. Two-stage surgical procedures should be avoided in elderly patients. Implant restorations for elderly patients should be designed so that they can be modified to become low-maintenance prostheses, or even be removed, as a strategy to facilitate oral hygiene and comfort in the final stage of life. © 2016 John Wiley & Sons A/S.

    Little is known about acute hemodialysis in the US. Here we describe predictors of receipt of acute hemodialysis in one state and estimate the marginal impact of acute hemodialysis on survival after accounting for confounding due to illness severity. This is a retrospective cohort study of acute-care hospitalizations in Pennsylvania from October 2005 to December 2007 using data from the Pennsylvania Health Care Cost Containment Council. Exposure variable is acute hemodialysis; dependent variable is survival following acute hemodialysis. We used multivariable logistic regression to determine propensity to receive acute hemodialysis and then, for a Cox proportional hazards model, matched acute hemodialysis and non-acute hemodialysis patients 1∶5 on this propensity. In 2,131,248 admissions of adults without end-stage renal disease, there were 6,657 instances of acute hemodialysis. In analyses adjusted for predicted probability of death upon admission plus other covariates and stratified on age, being male, black, and insured were independent predictors of receipt of acute hemodialysis. One-year post-admission mortality was 43% for those receiving acute hemodialysis, compared to 13% among those not receiving acute hemodialysis. After matching on propensity to receive acute hemodialysis and adjusting for predicted probability of death upon admission, patients who received acute hemodialysis had a higher risk of death than patients who did not over at least 1 year of follow-up (hazard ratio 1·82, 95% confidence interval 1·68-1·97). In a populous US state, receipt of acute hemodialysis varied by age, sex, race, and insurance status even after adjustment for illness severity. In a comparison of patients with similar propensity to receive acute hemodialysis, those who did receive it were less likely to survive than those who did not. These findings raise questions about reasons for lack of benefit.

    With a modified version of the Ways of Coping Checklist, the relation of coping to adherence among 57 hemodialysis patients was examined. The association of a particular type of coping to adherence was predicted to depend on the specific type of stressful encounter being considered. As predicted, coping efforts involving planful problem solving were associated with more favorable adherence when used in response to stressors involving a relatively controllable aspect of the hemodialysis context. For less controllable stressors, coping efforts involving emotional self-control were associated with more favorable adherence. The seeking of informational support in response to an uncontrollable encounter was associated with poorer fluid-intake adherence. Confrontive coping was associated with poorer adherence for both high- and low-control situations.

    The purpose of this study was to evaluate nonadherence to diet and fluid restrictions and its relation with the level of disability in patients on chronic hemodialysis (CH). The study design was a descriptive survey. The data were obtained from 186 patients in hemodialysis centers in Turkey. Descriptive statistics including mean scores, standard deviations and frequencies, and correlations analysis and logistic regression were conducted. Data were collected by using a personal information form, the Dialysis Diet and Fluid and Brief Disability Questionnaire. A great majority of hemodialysis patients showed nonadherence to diet and fluid restrictions. In total, 124 patients (66.7 %) reported mild to very severe nonadherence to diet, and 128 patients (68.8 %) reported mild to very severe nonadherence to fluid restrictions. Most of the patients with CH (69.9 %) experienced disability. The results of this study showed that nonadherence was more common among older age, females, low-educated patients and those with higher levels of disability. The results of this study showed that the prevalence of nonadherence to diet and fluid restrictions was high in hemodialysis patients. The significant predictors for diet and fluid nonadherence were: older age, high interdialytic weight gain, and severe disability. Medical professionals must be aware of nonadherence and related factors and assist patients in developing strategies to prevent and respond to this.

    Hyperphosphatemia is one of the major complications of hemodialysis patients and plays a key role in the pathogenesis of cardiovascular calcification and secondary hyperparathyroidism. Dietary phosphate restriction and removal of phosphate by dialysis are insufficient to control hyperphosphatemia. Therefore, almost all patients undergoing hemodialysis should take oral phosphate binders. Sevelamer hydrochloride (sevelamer) is a novel phosphate-binding polymer that contains neither aluminum nor calcium, and it is not absorbed from the gastrointestinal tract. In rat models with progressive chronic renal insufficiency, in addition to lowering effects on serum levels of phosphorus, calcium x phosphorus product, and parathyroid hormone, dietary treatment of sevelamer can prevent parathyroid hyperplasia, vascular calcification, high turnover bone lesion, and renal functional deterioration. In clinical studies with hemodialysis patients, sevelamer lowers serum phosphorus and calcium x phosphorus product without any incidence of hypercalcemia. Switching calcium-containing phosphate binders to sevelamer can decrease the percentage of hypoparathyroidism and hyperparathyroidism by negative calcium balance and increased dosage of vitamin D, respectively. Sevelamer also decreases serum low-density lipoprotein cholesterol levels by its bile acid-binding capacity. A long-term clinical study has demonstrated that the progression of coronary and aortic calcification in hemodialysis patients is attenuated by sevelamer. Thus, sevelamer offers the promise of impacting cardiac calcification and thereby reducing morbidity and mortality of hemodialysis patients.

    Background Uremic pruritus is a common and intractable symptom in patients on chronic hemodialysis, but factors associated with the severity of pruritus remain unclear. This study aimed to explore the associations of metabolic factors and dialysis adequacy with the aggravation of pruritus. Methods We conducted a 5-year prospective cohort study on patients with maintenance hemodialysis. A visual analogue scale (VAS) was used to assess the intensity of pruritus. Patient demographic and clinical characteristics, laboratory parameters, dialysis adequacy (assessed by Kt/V), and pruritus intensity were recorded at baseline and follow-up. Change score analysis of the difference score of VAS between baseline and follow-up was performed using multiple linear regression models. The optimal threshold of Kt/V, which is associated with the aggravation of uremic pruritus, was determined by generalized additive models and receiver operating characteristic analysis. Results A total of 111 patients completed the study. Linear regression analysis showed that lower Kt/V and use of low-flux dialyzer were significantly associated with the aggravation of pruritus after adjusting for the baseline pruritus intensity and a variety of confounding factors. The optimal threshold value of Kt/V for pruritus was 1.5 suggested by both generalized additive models and receiver operating characteristic analysis. Conclusions Hemodialysis with the target of Kt/V ≥1.5 and use of high-flux dialyzer may reduce the intensity of pruritus in patients on chronic hemodialysis. Further clinical trials are required to determine the optimal dialysis dose and regimen for uremic pruritus. PMID:23940749

    Hemoglobin variability is a common problem among hemodialysis patients. We have previously demonstrated an association between Hb variability and left ventricular mass index. In this study, we investigated a possible relation between Hb variability and carotid intima-media thickness (CIMT). Twelve-month hemoglobin (Hb) values of 135 patients on maintenance hemodialysis were examined retrospectively. The range of 11-12 gr/dl was accepted as normal according to the KDOQI guidelines. Hemoglobin levels were classified as: Hb < 11 gr/dl:Low, Hb = 11-12 gr/dl:Normal and Hb > 12 gr/dl:High. According to 12-month Hb trajectory, the patients were divided into three groups: low-normal (LN), normal-high (NH) and low-high (LH). The CIMT measurements were taken on common carotid arteries bilaterally, and the average of these measurements were taken. The groups were compared in terms of CIMT measurements, demographic and laboratory features. The LN, NH and LH groups were similar in terms of age, gender, incidence of diabetes mellitus, hypertension and cardiovascular diseases. Duration of hemodialysis, hemodialysis adequacy, serum lipids and CaxP products were also similar among the groups. The mean CIMT value was 0.601 ± 0.107, 0.744 ± 0.139 and 0.604 ± 0.134 mm in the LN, LH and NH groups, respectively (p < 0.001). CIMT was significantly higher in LH than in the other two groups. In our study, when the three groups with similar risk factors for atherosclerosis were examined, we found that the LH group with the highest hemoglobin variability has the highest CIMT. This study is the first study to demonstrate that Hb variability is associated with an increase in CIMT in HD patients.

    There are many factors that can affect dialysis adequacy; such as the type of vascular access, filter type, device used, and the dose, and rout of erythropoietin stimulation agents (ESA) used. The aim of this study was investigating factors affecting Hemodialysis adequacy in cohort of Iranian patient with end stage renal disease (ESRD). This is a cross-sectional study conducted on 133 Hemodialysis patients referred to two dialysis units in Sistan-Baluchistan province in the cities of Zabol and Iranshahr, Iran. We have looked at, (the effects of the type of vascular access, the filter type, the device used, and the dose, route of delivery, and the type of ESA used) on Hemodialysis adequacy. Dialysis adequacy was calculated using kt/v formula, two-part information questionnaire including demographic data which also including access type, filter type, device used for hemodialysis (HD), type of Eprex injection, route of administration, blood groups and hemoglobin response to ESA were utilized. The data was analyzed using the SPSS v16 statistical software. Descriptive statistical methods, Mann-Whitney statistical test, and multiple regressions were used when applicable. The range of calculated dialysis adequacy is 0.28 to 2.39 (units of adequacy of dialysis). 76.7% of patients are being dialyzed via AVF and 23.3% of patients used central venous catheters (CVC). There was no statistical significant difference between dialysis adequacy, vascular access type, device used for HD (Fresenius and B. Braun), and the filter used for HD (p> 0.05). However, a significant difference was observed between the adequacy of dialysis and Eprex injection and patients' time of dialysis (p <0.05). Subcutaneous ESA (Eprex) injection and dialysis shift (being dialyzed in the morning) can have positive impact on dialysis adequacy. Patients should be educated on the facts that the type of device used for HD and the vascular access used has no significant effects on dialysis adequacy.

    Hemodialysis patients are a high-risk group for hepatitis B and C virus infections. The aim of the study was to evaluate the prevalence of B and C viral hepatitis, level of its control among patients on hemodialysis. In December of 1997, 1998, 1999, 2000, 2001 we visited all hemodialysis centers of Lithuania and gathered information about these infections in patients on hemodialysis. Eleven percent (11.4%) of all hemodialysis patients were not examined for HB(s)Ag and 15.2% for anti-HCV, 67.3%--for anti-HB(s) and 57.7% for anti-HBc in 2001. The number of examined patients for the markers of hepatitis had increased in 2001 in comparison with 1997. The same number of hemodialysis patients with HB(s)Ag was found in each year of study (14% in 1997, 14.4% in 2001). We observed the decrease in percentage of anti-HCV positive patients from 23% in 1998 till 15.4% (p<0.01) in 2001. Only 10.6% hepatitis B virus vaccinated patients was registered in 2001 and this percentage increased if compared to 6.3% in 1999. About (1/4) of anti-HB(c) positive patients were HB(s)Ag positive in 2000-2001. Chronic hepatitis B could be diagnosed for them. The duration of hemodialysis of HB(s)Ag and anti-HCV positive patients was longer compared to HB(s)Ag and anti-HCV negative patients (p<0.001).

    Anxiety is a common yet frequently overlooked psychiatric symptom in patients with ESRD treated with hemodialysis (HD). Anxiety is characterized by disruptive feelings of uncertainty, dread, and fearfulness. A variety of common medical complaints may be manifestations of an anxiety disorder, including palpitations, tremors, indigestion, numbness/tingling, nervousness, shortness of breath, diaphoresis, and fear. It is essential for the clinician to rule out specific medical conditions, including cardiovascular, pulmonary, and neurologic diseases, before ascribing these symptoms to an anxiety disorder. In addition, there is considerable overlap between the symptoms of anxiety and those of depression and uremia. This psychiatric condition has a significant adverse impact on patients' perception of quality of life. Little is known regarding the prevalence and impact of anxiety disorders in patients with ESRD treated with HD; however, many of the seemingly irrational behaviors of patients, or behaviors which place them in conflict with staff and physicians, such as behavioral noncompliance, may be the expression of an underlying anxiety disorder. In this review, we present three clinical vignettes, highlighting the impact of anxiety disorders in patients with ESRD treated with HD. Copyright © 2016 by the American Society of Nephrology.

    Affective disorders, particularly depression, are the commonest and probably the most important psychopathological complication of end stage renal disease (ESRD). Depression has the potential to alter adversely the medical outcome of ESRD patients and the psychological stress can affect patient's adherence to medication regimen. In Iraq as well as many other Arab countries, the true prevalence of depression among ESRD patients is unknown. The objective of this study was to determine the prevalence of depression among a cohort of Iraqi hemodialysis (HD) patients and relate it to their socio-demographic characteristics. We recruited patients from two HD centers in Baghdad, excluding patients with history of depression or other psychiatric disorders prior to the initiation of HD. The Arabic version of diagnostic and statistical manual of mental disorders fourth edition (DSM-IV) was used to diagnose depression. Beck's Depression Inventory was used to grade its severity. Clinical and laboratory data of the study group were documented and related to the diagnosis of depression. Seventy-five Iraqi patients on maintenance HD were included in the study. Patients' duration on HD ranged from six months to five years. The prevalence of depression among this cohort of HD patients was 80%. The prevalence of severe, moderate and mild depression was 25%, 50% and 25% respectively. The mean depression score was 17.1. Female gender, unemployment, and marital status had statistically significant associations with depression. Depression is common in this group of Iraqi HD patients and its prevalence is comparable to the results of similar studies in other societies.

    Evidence-informed decision-making in clinical care and policy in nephrology is undermined by trials that selectively report a large number of heterogeneous outcomes, many of which are not patient-centered. The Standardized Outcomes in Nephrology−Hemodialysis (SONG-HD) Initiative convened an international consensus workshop on November 7, 2015, to discuss the identification and implementation of a potential core outcome set for all trials in hemodialysis. The purpose of this article is to report qualitative analyses of the workshop discussions, describing the key aspects to consider when establishing core outcomes in trials involving patients on hemodialysis. Key stakeholders including eight patients/caregivers and 47 health professionals (nephrologists, policy makers, industry, researchers) attended the workshop. Attendees suggested that identifying core outcomes required equitable stakeholder engagement to ensure relevance across patient populations; flexibility to consider evolving priorities over time; deconstruction of language and meaning for conceptual consistency and clarity; understanding of potential overlap and associations between outcomes; and an assessment of applicability to the range of interventions in hemodialysis. For implementation, they proposed that core outcomes must have simple, inexpensive and validated outcome measures that could be used in clinical care (quality ndicators) and trials (including pragmatic trials), and endorsement by regulatory agencies. Integrating these recommendations may foster acceptance and optimize the uptake and translation of core outcomes in hemodialysis, leading to more informative research, for better treatment, and improved patient outcomes.

    Evidence-informed decision making in clinical care and policy in nephrology is undermined by trials that selectively report a large number of heterogeneous outcomes, many of which are not patient centered. The Standardized Outcomes in Nephrology-Hemodialysis (SONG-HD) Initiative convened an international consensus workshop on November 7, 2015, to discuss the identification and implementation of a potential core outcome set for all trials in hemodialysis. The purpose of this article is to report qualitative analyses of the workshop discussions, describing the key aspects to consider when establishing core outcomes in trials involving patients on hemodialysis therapy. Key stakeholders including 8 patients/caregivers and 47 health professionals (nephrologists, policymakers, industry, and researchers) attended the workshop. Attendees suggested that identifying core outcomes required equitable stakeholder engagement to ensure relevance across patient populations, flexibility to consider evolving priorities over time, deconstruction of language and meaning for conceptual consistency and clarity, understanding of potential overlap and associations between outcomes, and an assessment of applicability to the range of interventions in hemodialysis. For implementation, they proposed that core outcomes must have simple, inexpensive, and validated outcome measures that could be used in clinical care (quality indicators) and trials (including pragmatic trials) and endorsement by regulatory agencies. Integrating these recommendations may foster acceptance and optimize the uptake and translation of core outcomes in hemodialysis, leading to more informative research, for better treatment and improved patient outcomes.

    To explore the association between the sociodemographic factors and the needs of patients undergoing hemodialysis in Taiwan. Concomitant discomfort, including physical and mental aspects, affects the patients' quality of life and their willingness to undergo hemodialysis. Maslow's hierarchy of needs is a well-known tool to assess different levels of human needs. We conducted a small-scale cross-sectional observational study using a structured needs assessment questionnaire on 159 patients from the Taipei Veterans General Hospital hemodialysis unit. The overall mean scores of physical, mental, spiritual, other needs, and needs in relation to medical staff care were 4.0±0.8, 3.2±0.8, 2.7±1.0, 3.1±0.9, and 4.1±0.7, respectively. The results showed that the patients' highest need was in relation to medical staff care, followed by physical needs. Further analysis showed that patients who are still employed during the treatment process have higher mental, spiritual, and other needs. Patient who are financially supported by their family have higher physical needs. Patients taken cared of by paid caregivers have lower spiritual needs and other needs. This is also the same with patients who are religious as opposed to those who are non-religious. Patients who have attained tertiary education have higher other needs compared to patients who have only achieved up to primary or secondary education. The study is the first in Taiwan to identify and quantify the needs of patients undergoing hemodialysis. When the needs of the patients are identified in relation to their sociodemographic factors, the medical staff can give the appropriate treatment in order to meet the needs and improve the patients' well-being. Healthcare providers should not only focus on the patients' physiological needs, but should determine and address their other needs in various aspects in order to improve the quality and efficacy of the dialysis care process.

    Assess the effect of intensive nutrition education by trained dedicated dietitians on osteodystrophy management among hemodialysis patients. Randomized controlled trial in 12 hospital-based hemodialysis units equally distributed over clusters 1 and 2. Cluster 1 patients were either assigned to usual care (n=96) or to individualized intensive staged-based nutrition education by a dedicated renal dietitian (n=88). Cluster 2 patients (n=210) received nutrition education from general hospital dietitians, educating their patients at their spare time from hospital duties. Main outcomes were: (1) dietary knowledge(%), (2) behavioral change, (3) serum phosphorus (mmol/L), each measured at T0 (baseline), T1 (post 6 month intervention) and T2 (post 6 month follow up). Significant improvement was found only among patients receiving intensive education from a dedicated dietitian at T1; the change regressed at T2 without statistical significance: knowledge (T0: 40.3; T1: 64; T2: 63) and serum phosphorus (T0: 1.79; T1: 1.65; T2: 1.70); behavioral stages changed significantly throughout the study (T0: Preparation, T1: Action, T2: Preparation). The intensive protocol showed to be the most effective. Integrating dedicated dietitians and stage-based education in hemodialysis units may improve the nutritional management of patients in Lebanon and countries with similar health care systems.

    Appropriate glycemic control without hypoglycemia is important in patients with type 2 diabetes on hemodialysis. Teneligliptin, a novel dipeptidyl peptidase-4 inhibitor, can be used without dose adjustment for these patients. Using continuous glucose monitoring (CGM), we evaluated the efficacy and safety of adding teneligliptin to insulin therapy. Twenty-one type 2 diabetes mellitus patients on hemodialysis treated with insulin were enrolled. After the adjustment of insulin dose, their blood glucose level was monitored by CGM. Insulin dose was reduced after teneligliptin administration. The median total daily insulin dose significantly reduced from 18 (9-24)U to 6 (0-14)U (p<0.0001). Maximum, mean, and standard deviation of blood glucose level on the hemodialysis and non-hemodialysis days did not change after teneligliptin administration. However, minimum blood glucose level was significantly elevated on the hemodialysis day after teneligliptin administration (from 3.9±1.0mmol/L to 4.4±0.9mmol/L, p=0.040). The incidence of asymptomatic hypoglycemia on the hemodialysis day detected by CGM significantly decreased from 38.1% to 19.0% (p=0.049). Teneligliptin may contribute toward reducing the total daily insulin dose and preventing hypoglycemic events on the hemodialysis day in type 2 diabetes mellitus patients.

    Recent evidence from adult hemodialysis (HD) patient studies reveal improved biochemical control and reported health-related quality of life after transition from conventional thrice weekly to daily home maintenance HD treatment. Published pediatric frequent dialysis experiences demonstrate similar improvement but all used conventional HD machines, which employ a treated municipal water supply, thereby frequently exposing patients to proinflammatory components. We report our pediatric experience with six-times-weekly HD using the NxStage system, which uses sterile dialysis fluid to provide dialysis in the home or center setting. Four patients (weight range 38-61.4 kg) completed the 16-week study. Patients exhibited progressive reductions in casual pretreatment systolic and diastolic blood pressures, discontinuation of antihypertensive medications, and decreased blood pressure load by ambulatory blood pressure monitoring. Mean serum phosphorus improved without change in phosphorus binder medication, and all three patients with a normalized protein catabolic rate <1 g/kg per day at the beginning of the study improved to a normalized protein catabolic rate (nPCR) of >1.1 g/kg per day. Patients reported no adverse effects. Variable changes in proinflammatory cytokine levels were observed. We suggest that frequent HD with the NxStage system be considered for children who would benefit from home-based maintenance dialysis.

    Clinical outcomes after a hospital discharge are poorly defined for patients receiving maintenance in-center (outpatient) hemodialysis. To describe the proportion and characteristics of these patients who are rehospitalized, visit an emergency department, or die within 30 days after discharge from an acute hospitalization, we conducted a population-based study of all adult patients receiving maintenance in-center hemodialysis who were discharged between January 1, 2003, and December 31, 2011, from 157 acute care hospitals in Ontario, Canada. For patients with more than one hospitalization, we randomly selected a single hospitalization as the index hospitalization. Of the 11,177 patients included in the final cohort, 1926 (17%) were rehospitalized, 2971 (27%) were treated in the emergency department, and 840 (7.5%) died within 30 days of discharge. Complications of type 2 diabetes mellitus were the most common reason for rehospitalization, whereas heart failure was the most common reason for an emergency department visit. In multivariable analysis using a cause-specific Cox proportional hazards model, the following characteristics were associated with 30-day rehospitalization: older age, the number of hospital admissions in the preceding 6 months, the number of emergency department visits in the preceding 6 months, higher Charlson comorbidity index score, and the receipt of mechanical ventilation during the index hospitalization. Thus, a large proportion of patients receiving maintenance in-center hemodialysis will be readmitted or visit an emergency room within 30 days of an acute hospitalization. A focus on improving care transitions from the inpatient setting to the outpatient dialysis unit may improve outcomes and reduce healthcare costs.

    Refractory pleural effusion can be a life-threatening complication in patients receiving maintenance hemodialysis. We report successful treatment of refractory pleural effusion using a Denver® pleuroperitoneal shunt in one such patient. A 54-year-old Japanese man, who had previously undergone left nephrectomy, was admitted urgently to our department because of a high C-reactive protein (CRP) level, right pleural effusion, and right renal abscess. Because antibiotics proved ineffective and his general state was deteriorating, he underwent emergency insertion of a thoracic drainage tube and nephrectomy, and hemodialysis was started. Although his general state improved slowly thereafter, the pleural effusion, which was unilateral and transudative, remained refractory and therefore he needed to be on oxygenation. To control the massive pleural effusion, a pleuroperitoneal shunt was inserted. Thereafter, his respiratory condition became stable without oxygenation and he was discharged. His general condition has since been well. Although pleural effusion is a common complication of maintenance hemodialysis, few reports have documented the use of pleuroperitoneal shunt to control refractory pleural effusion. Pleuroperitoneal shunt has been advocated as an effective and low-morbidity treatment for refractory pleural effusion, and its use for some patients with recurrent pleural effusion has also been reported, without any severe complications. In the present case, pleuroperitoneal shunt improved the patient's quality of life sufficiently to allow him to be discharged home without oxygenation. Pleuroperitoneal shunt should be considered a useful treatment option for hemodialysis patients with refractory pleural effusion.

    Decreased residual urine volume (RUV) is associated with higher mortality in hemodialysis (HD). However, few studies have examined RUV in patients on HD in Sub-Saharan Africa. The aim of this study was to identify predictors of RUV among incident hemodialysis patients in Kinshasa. This historical cohort study enrolled 250 patients with ESRD undergoing hemodialysis between January 2007 and July 2013 in two hemodialysis centers in Kinshasa. RUV were collected over 24 h at the initiation of HD and 6 and 12 months later during the interdialytic period. We compared the baseline characteristics of the patients according to their initial RUV (≤ 500 ml/day vs >  500 ml/day) using Student's t, Mann-Whitney U and Chi2 tests. Linear mixed-effects models were used to search for predictors of decreased RUV by adding potentially predictive baseline covariates of the evolution of RUV to the effect of time: age, sex, diabetes mellitus, hypertension, diastolic blood pressure, diuretics, angiotensin conversion enzyme inhibitors (ACEI), angiotensin receptor blockers, hypovolemia, chronic tubulointerstitial nephropathy, left ventricular hypertrophy and initial hemodialysis characteristic. A value of p < 0.05 was considered the threshold of statistical significance. The majority of hemodialysis patients were male (68.8%, sex ratio 2.2), with a mean age of 52.5 ± 12.3 years. The population's RUV decreased with time, but with a slight deceleration. The mean RUV values were 680 ± 537 ml/day, 558 ± 442 ml/day and 499 ± 475 ml/day, respectively, at the initiation of HD and at 6 and 12 months later. The use of ACEI at the initiation of HD (beta coefficient 219.5, p < 0.001) and the presence of chronic tubulointerstitial nephropathy (beta coefficient 291.8, p = 0.007) were significantly associated with RUV preservation over time. In contrast, the presence of left ventricular hypertrophy at the initiation of HD was significantly associated with

    The objective of this single-arm interventional pilot study was to determine whether viewing an educational video about phosphorous and phosphorous control by patients on hemodialysis was associated with improved phosphorous values and improvement in knowledge and attitudes about the topics presented. An educational video was shown to 150 patients at 16 dialysis centers. The change in serum phosphate levels before and after the viewing of an educational video was evaluated. Mean phosphorous levels for patients were lower in the month after viewing the educational video compared to their values over the three months before the video was shown (6.35 versus 6.82 g/dL). This difference was statistically significant on a per patient basis (-0.47 g/dL, p = 0.0006). Of these patients, all with phosphorus levels outside of the normal range (3.5 to 5.5 mg/dL) before viewing the video, 28.4% had phosphorus levels within the normal range within a month after viewing the video. Patients on hemodialysis who watched an educational video had improved phosphorous levels in the month after viewing the video when compared to phosphorus levels over the three months before the video was shown. The video intervention has the advantages of being simple, low-cost, and easy to implement, and is associated with improved phosphorous levels in patients undergoing hemodialysis. The video increased patient compliance with recommended self-care regimens.

    The start of dialysis treatment is a critical step in the care management of chronic renal failure patients. When hemodialysis is performed three times a week, rapid loss of kidney function and of urine volume output generally occur and this represents an unfavorable prognostic factor. Instead, reducing frequency of hemodialysis sessions, as well as peritoneal dialysis, can contribute to a lesser decrease of residual renal function. Unfortunately, the existing protocols for an incremental hemodialysis approach are not particularly common and they are generally limited to a twice a week hemodialysis schedule. In addition to clinical and economic reasons, an incremental approach to ESRD also contributes to better social and psychological adaptation by the patients to the dramatic change in living conditions linked to the maintenance dialysis treatment. In patients who have attitude for low-protein nutritional therapy, a once weekly dialysis schedule combined with low-protein, low-phosphorus, normal to high energy diet in the remaining six days of the week can be implemented in selected patients. In our experience, this kind of program produced important clinical results and reduction in costs and hospitalization. When compared with a three times a week dialysis schedule, a greater protection of residual renal function and of urine volume output, lower increase in 2 microglobulin, better control of phosphorus and less consumption of phosphate binders and erythropoietin were observed. Careful clinical monitoring and nutrition is essential for the safety and optimization of infrequent hemodialysis. Long-term follow-up analysis shows favorable effects on the overall survival. Furthermore, twice a week hemodialysis is not the only option for an incremental approach of dialysis commencing. In patients who have a good attitude for low-protein nutritional therapy, its arrangement with a program of once weekly dialysis represents a real and effective alternative.

    This short-term study assessed the efficacy and safety of calcium carbonate combined with calcitonin in the treatment of hypercalcemia in hemodialysis patients. Patients (n=64) on hemodialysis for chronic kidney disease for more than 6 months were included based on total serum calcium more than 10.5 mg/dL. All patients were randomized (1:1) to receive calcium carbonate combined with calcitonin (Group I) or lanthanum carbonate (Group II) for 12 weeks. Blood levels of calcium, phosphorus and intact parathyroid hormone (iPTH) were measured every month, bone mass density (BMD) and coronary artery calcium scores (CACS) were measured at 3 months. During the study period, serum calcium decreased from 10.72 ± 0.39 to 10.09 ± 0.28 mg/dL (P < 0.05), serum phosphorus decreased from 6.79 ± 1.05 to 5.46 ± 1.18 mg/dL (P < 0.05), and serum iPTH levels in the Group I and Group II were not significantly different from the baseline. There were no significant differences in CACS in either group. There were no significant differences in the BMD values between Group I and baseline. In Group II, the BMD values at the lumbar spine and femoral neck were significantly lower than those before the trial and significantly lower than the corresponding values of Group I (P<0.05). Calcium carbonate combined with calcitonin and lanthanum carbonate were equally effective in the suppression of hypercalcemia in hemodialysis patients. There were no serious treatment-related adverse events in treatment with calcium carbonate combined with calcitonin. © 2014 The Authors.

    Identifying predictors of physical incapacity degree in patients on chronic hemodialysis in Kinshasa. Bicentric analytical study, between January 2007 and July 2013. Degree of physical handicap was evaluated at 6months of hemodialysis based on the scale of Rosser. Logistic regression sought the predictors of no or light physical incapacity (Rosser<3) vs. moderate to maximum (Rosser≥3). P was set at 0.05. One hundred twenty-seven patients (127) patients received at least 6months of hemodialysis (53.3±11years; 73.2 % male), 79 (62.2 %) had no or light incapacity and 48 (37.8 %) moderate to maximum. Predictors of lower physical incapacity in univaried analysis were: secured funding, high socioeconomic level, lack of diabetes mellitus, high body weight, normal systolic and diastolic blood pressure, residual diuresis 3months later, hemoglobin and hematocrit, low comorbidity, arteriovenous fistula, erythropoietin, at least 12hours of hemodialysis per week and lack of intradialytic complications. After logistic regression, a high residual diuresis 3months of hemodialysis has proved an independent predictor of lower physical Incapacity (aOR 0.998; P=0.024) next to the lack of diabetes mellitus (aOR 0.239; P=0.024), good control of systolic (aOR 0.958; P=0.013) and diastolic (aOR 1.089; P=0.003) blood pressure and the use of erythropoietin (aOR 5.687; P=0.004). Preserving residual diuresis is associated with lower physical incapacity and must be integrated in the management in hemodialysis. Copyright © 2016 Association Société de néphrologie.

    Harp, Richard J.; Stavropoulos, S. William; Wasserstein, Alan G.

    Purpose: Percutaneous hemodialysis thrombectomy causes subclinical pulmonary emboli without short-term clinical consequence; the long-term effects on the pulmonary arterial vasculature are unknown. We compared the prevalence of pulmonary hypertension between patients who underwent one or more hemodialysis access thrombectomy procedures with controls without prior thrombectomy.Methods: A retrospective case-control study was performed. Cases (n = 88) had undergone one or more hemodialysis graft thrombectomy procedures, with subsequent echocardiography during routine investigation of comorbid cardiovascular disease. Cases were compared with controls without end-stage renal disease (ESRD) (n = 100, group 1), and controls with ESRD but no prior thrombectomy procedures (n =more » 117, group 2). The presence and velocity of tricuspid regurgitation on echocardiography was used to determine the prevalence and grade of pulmonary hypertension; these were compared between cases and controls using the chi-square test and logistic regression.Results: The prevalence of pulmonary hypertension among cases was 52% (46/88), consisting of mild, moderate and severe in 26% (n = 23), 10% (n = 9) and 16% (n = 14), respectively. Prevalence of pulmonary hypertension among group 1 controls was 26% (26/100), consisting of mild, moderate and severe pulmonary hypertension in 14%, 5% and 7%, respectively. Cases had 2.7 times greater odds of having pulmonary hypertension than group 1 controls (p = 0.002). The prevalence of pulmonary hypertension among group 2 controls was 42% (49/117), consisting of mild, moderate and severe pulmonary arterial hypertension in 25% (n = 49), 10% (n = 12) and 4% (n = 5), respectively. Cases were slightly more likely to have pulmonary hypertension than group 2 controls (OR = 1.5), although this failed to reach statistical significance (p = 0.14).Conclusion: Prior hemodialysis access thrombectomy does not appear to be a risk factor for pulmonary arterial

    The guideline committee of Japanese Society for Dialysis Therapy (JSDT), chaired by Professor F. Gejyo of Niigata University, now publishes an original Japanese guideline entitled 'Guidelines for Renal Anemia in Chronic Hemodialysis Patients'. It includes the re-evaluation of the usage of recombinant human erythropoietin (rHuEPO) with the medical and economical arguments regarding the prognosis and the quality of life of Japanese hemodialysis patients. This guideline consists of 7 sections. The first section comprises the general definition and the differential diagnosis of anemia. The hemoglobin (Hb) level of the Japanese population seemed to be low when compared with that of the European and American populations. The second section describes the target Hb level in hemodialysis patients. Multivariate analysis of the data that were collected from dialysis institutions throughout the country showed that an Hb level of 10-11 g/dL (Ht level 30-33%) at the first dialysis session in a week is the ideal range for chronic hemodialysis patients in terms of the 3-5 year survival rate. The supine position at blood sampling and the sampling timing at the first dialysis session in a week might affect the lower setting of target Hb hematocrit (Ht), compared to that of European and American guidelines. However, we particularly recommended that an Hb level of 11-12 g/dL (Ht level from 33 to 36%) at the first dialysis session in a week is desirable in relatively young patients. In the third section, the markers of iron deficiency are discussed. The Transferin saturation test (TSAT) and serum ferritin were emphasized as the standard markers. The routes of administration of rHuEPO and its dosages are written in the fourth section. The subcutaneous route was associated with the occurrence of secondary red cell aplasia due to anti-rHuEPO antibodies; however, secondary red cell aplasia was seldom observed in the venous injection. From this fact we recommend venous injection for chronic

    Background: Despite the high levels of inflammation in hemodialysis patients and the effects of diet on systemic inflammation, such as the development of atherosclerosis and cardiovascular disease, few studies have evaluated the relationship of macronutrients and antioxidants intake with serum C-reactive protein (CRP). Therefore, this study assessed the relationship between serum high sensitivity CRP (hs-CRP) with macronutrients and antioxidants intake and serum albumin. Methods: This cross-sectional study used census sampling to select 75 hemodialysis patients (35 men and 40 women) who attended the hemodialysis department of Vaseie Hospital of Sabzevar, Iran. After obtaining the written consent, all the patients were interviewed and dietary data was collected by using a semi-quantitative food frequency questionnaire including 160 food items. Diet analysis was performed with Nutritionist IV. Before being connected to the dialysis machine, 5 cc fasting blood samples were obtained from all participants and serum hs-CRP and albumin levels were measured. All the statistical analyses were conducted with SPSS -for Windows, version 16.0. Results: The patients' mean body mass index was 20.09 ± 3.27 kg/ m2. The participants' intake of antioxidants and all macronutrients, except for carbohydrates and proteins, was less than the standard levels. Moreover, the hs-CRP had significant inverse relationships with serum albumin (P=0.0001) and vitamin E and C intakes but was not significant. Also, a significant relationship was observed between hs-CRP levels and the intake of energy (P=0.002) and protein (P=0.0001). Conclusion: Our findings indicated hs-CRP levels of hemodialysis patients to have significant inverse relationships with serum albumin and vitamin E and C intakes but was not significant. Also, a significant relationship was observed between hs-CRP levels and the intake of energy and protein.

    There are conflicting research results about the survival differences between hemodialysis and peritoneal dialysis, especially during the first 2 years of dialysis treatment. Given the challenges of conducting randomized trials, differential rates of modality switch and transplantation, and time-varying confounding in cohort data during the first years of dialysis treatment, use of novel analytical techniques in observational cohorts can help examine the peritoneal dialysis versus hemodialysis survival discrepancy. This study examined a cohort of incident dialysis patients who initiated dialysis in DaVita dialysis facilities between July of 2001 and June of 2004 and were followed for 24 months. This study used the causal modeling technique of marginal structural models to examine the survival differences between peritoneal dialysis and hemodialysis over the first 24 months, accounting for modality change, differential transplantation rates, and detailed time-varying laboratory measurements. On dialysis treatment day 90, there were 23,718 incident dialysis-22,360 hemodialysis and 1,358 peritoneal dialysis-patients. Incident peritoneal dialysis patients were younger, had fewer comorbidities, and were nine and three times more likely to switch dialysis modality and receive kidney transplantation over the 2-year period, respectively, compared with hemodialysis patients. In marginal structural models analyses, peritoneal dialysis was associated with persistently greater survival independent of the known confounders, including dialysis modality switch and transplant censorship (i.e., death hazard ratio of 0.52 [95% confidence limit 0.34-0.80]). Peritoneal dialysis seems to be associated with 48% lower mortality than hemodialysis over the first 2 years of dialysis therapy independent of modality switches or differential transplantation rates.

We used mass spectrometry to measure plasma concentrations of the 25 elements at baseline, 6 months, 1 year, and 2 years following enrollment in the cohort. We focused on low concentrations of zinc, selenium, and manganese and excessive concentrations of lead, arsenic, and mercury; low and excessive concentrations of the other 19 trace elements were treated as exploratory analyses. Low and excessive concentrations were based on the 5th and 95th percentile plasma concentrations from healthy reference populations. At all 4 occasions, low zinc, selenium, and manganese concentrations were uncommon in study participants (≤5.1%, ≤1.8%, and ≤0.9% for zinc, selenium, and manganese, respectively) and a substantial proportion of participants had concentrations that exceeded the 95th percentile (≥65.2%, ≥74.2%, and ≥19.7%, respectively). Almost all participants had plasma lead concentrations above the 95th percentile at all time points. The proportion of participants with plasma arsenic concentrations exceeding the 95th percentile was relatively constant over time (9.1%-9.8%); the proportion with plasma mercury concentrations that exceeded the 95th percentile varied between 15.2% and 29.3%. Low arsenic, platinum, tungsten, and beryllium concentrations were common (>50%), as were excessive cobalt, manganese, zinc, vanadium, cadmium, selenium, barium, antimony, nickel, molybdenum, lead, and chromium concentrations. There was no evidence that low zinc, selenium, or manganese concentrations exist in most contemporary Canadian hemodialysis patients. Some patients have excessive plasma arsenic and mercury concentrations, and excessive lead concentrations were common

    The international cohort of hemodialysis patients is aging and increasing in number. Nephrologists have a therapeutic relationship with their patients that may span decades. Often overlooked components of chronic disease management include symptom control and assessment of health-related quality of life (HRQoL). This study describes the symptom profile of a large cohort of patients with end-stage renal disease on hemodialysis in England and Ireland and evaluates how symptom burden and other factors influence quality-of-life scores. A prospective cross-sectional observational study of hemodialysis patients was conducted in Ireland and England during 2011 and 2012. Two validated clinical tools were used to determine HRQoL and symptom burden. Demographic and clinical data were examined, and regression analysis was used to determine associations with HRQoL scores. A total of 893 patients on hemodialysis (mean [SD] age 64 [16] years) had a high symptom burden and poor HRQoL compared with population norms. Specifically, 64% of patients reported pain (95% confidence interval 61%-67%) and 79% reported weakness (95% confidence interval 75%-81%). A total of 43 percent of patients reported between six and 10 symptoms in the week preceding the survey. HRQoL was significantly and independently associated with poor mobility and pain and remained significant after adjusting for variations in clinical characteristics. Being listed on a transplant wait-list register was positively associated with HRQoL. These findings illustrate the high symptom burden and poor HRQoL of the hemodialysis population. Emphasis during clinical reviews on pain assessment and on assessing mobility plus interventions, such as pain management and physiotherapy/occupational therapy, are practical ways for renal teams to help improve patients' quality of life.

    C-reactive protein (CRP) has been implicated as a possible mediator of the association between periodontitis and several systemic diseases. This study evaluated the impact of nonsurgical periodontal treatment on the serum levels of CRP in chronic kidney disease (CKD) patients on hemodialysis. A total of 77 CKD patients on hemodialysis were included in this study. At baseline, periodontal examination was assessed for all the patients, and chronic periodontitis was defined through clinical attachment level and probing pocket depth, according to the American Association of Periodontology. Nonsurgical periodontal treatment was performed and serum levels of CRP were evaluated at baseline and 8 weeks after periodontal treatment. Periodontal treatment resulted in significant reductions in CRP levels (p < 0.001). The difference between pre- and posttreatment CRP concentrations did not show any significant relationship with the severity of periodontitis. Periodontitis is an important source of systemic inflammation in CKD patients. Nonsurgical periodontal treatment can effectively reduce the serum level of CRP in these patients.

    Little is known about vascular access in patients starting hemodialysis therapy after kidney transplant failure. Retrospective cohort study. Adult patients (aged ≥18 years) who started hemodialysis therapy in Ontario, Canada, from January 1, 2001, through December 31, 2010, after kidney transplant failure. Patient clinical and demographic characteristics. Proportion and timing of arteriovenous (AV) vascular access creation (fistula or graft) 12 months prior and up to 24 months after starting hemodialysis therapy. Event rates and outcome predictors. Our cohort included 683 patients with a mean age of 48 years and >50% with comorbidity index score < 3. In the 12 months predialysis and 24 months postdialysis, 16% and 47% of patients had an AV access created, respectively. In the postdialysis period, 13%, 26%, and 38% of patients had an AV access creation at 3, 6, and 12 months, respectively. History of coronary artery disease, diabetes mellitus, and peritoneal dialysis use prior to transplantation were associated with a lower likelihood of AV access creation. Residual selection bias from unmeasured variables beyond the data elements. In Ontario, AV access creation, both before and after starting hemodialysis therapy, is low in patients with kidney transplant failure despite their being younger and healthier compared to the overall hemodialysis population. This highlights the need for a predialysis care pathway in the transplantation clinic and an active strategy to identify this patient cohort receiving hemodialysis to align modality and access choices.

    Pruritus is a common symptom among patients undergoing long-term hemodialysis. The effect of nicergoline, an ergoline, on pruritus was studied in products released during dialysis. In a first experiment series, 20 age-matched normal individuals, 25 patients receiving hemodialysis without pruritus, and 15 patients receiving hemodialysis with pruritus had intradermal tests with 500 micrograms of papaverine. All patients with pruritus had a small papaverine skin test response, and mean values were significantly (p less than 0.0001, Mann-Whitney U test) smaller in patients with pruritus. All patients with pruritus entered in a crossover, double-blind trial with nicergoline. In a first period of six dialyses, they received either nicergoline (daily oral dose, 30 mg, and intravenous dose during dialyses, 5 mg) or placebo. In the second period of six dialyses, patients received the crossover treatment. Nicergoline was effective in 13/15 patients, eight of these patients having a complete remission of pruritus. When nicergoline was stopped, patients relapsed within 24 to 48 hours. All patients who improved during the trial were then treated with a daily dose of 30 mg of nicergoline for 6 months. Seven patients had a complete remission, five had moderate symptoms, and one patient relapsed. This study demonstrated that some hemodialyzed patients with pruritus of unknown etiology had improvement with nicergoline.

    Fractures are frequent in patients receiving hemodialysis. We tested the hypothesis that cinacalcet would reduce the rate of clinical fractures in patients receiving hemodialysis using data from the Evaluation of Cinacalcet HCl Therapy to Lower Cardiovascular Events trial, a placebo-controlled trial that randomized 3883 hemodialysis patients with secondary hyperparathyroidism to receive cinacalcet or placebo for ≤64 months. This study was a prespecified secondary analysis of the trial whose primary end point was all-cause mortality and non-fatal cardiovascular events, and one of the secondary end points was first clinical fracture event. Clinical fractures were observed in 255 of 1935 (13.2%) patients randomized to placebo and 238 of 1948 (12.2%) patients randomized to cinacalcet. In an unadjusted intention-to-treat analysis, the relative hazard for fracture (cinacalcet versus placebo) was 0.89 (95% confidence interval [95% CI], 0.75 to 1.07). After adjustment for baseline characteristics and multiple fractures, the relative hazard was 0.83 (95% CI, 0.72 to 0.98). Using a prespecified lag-censoring analysis (a measure of actual drug exposure), the relative hazard for fracture was 0.72 (95% CI, 0.58 to 0.90). When participants were censored at the time of cointerventions (parathyroidectomy, transplant, or provision of commercial cinacalcet), the relative hazard was 0.71 (95% CI, 0.58 to 0.87). Fracture rates were higher in older compared with younger patients and the effect of cinacalcet appeared more pronounced in older patients. In conclusion, using an unadjusted intention-to-treat analysis, cinacalcet did not reduce the rate of clinical fracture. However, when accounting for differences in baseline characteristics, multiple fractures, and/or events prompting discontinuation of study drug, cinacalcet reduced the rate of clinical fracture by 16%-29%.

    Religious coping is known as a main resource influencing how individuals cope with the complications and stressors of chronic disease. The aim of this study was to assess the relationship between religious coping and quality of life among hemodialysis patients. This cross-sectional study was conducted in Qom, Iran, from June 2012 to July 2013. Ninety-five end-stage renal disease (ESRD) patients undergoing hemodialysis were selected via the convenience sampling method. Data were collected via a questionnaire comprising items on sociodemographic information, quality of life, the anxiety and depression scale, and religious coping. Following this, the data were analyzed using descriptive statistics and logistic regression analysis. The mean age of patients was 50.4 (standard deviation [SD] = 15.7) years, and most were male (61%). The mean score for positive religious coping was 23.38 (SD = 4.17), while that for negative religious coping was 11.46 (SD = 4.34). It was found that 53.6% of patients had higher than the mean score of positive religious coping, while those with negative religious coping made up 37.9%. Negative religious coping was associated with worse quality of life, including physical functioning (odds ratio [OR] = 0.72; P = 0.009), role physical (OR = 0.79; P = 0.04), vitality (OR = 0.62; P = 0.005), social functioning (OR = 0.69; P = 0.007), and mental health (OR = 0.58; P = 0.01) after controlling for sociodemographic, clinical, and anxiety and depression variables. The results indicated that patients with negative religious coping abilities were at risk of a suboptimal quality of life. Incorporating religious support in the care of hemodialysis patients may be helpful in improving quality of life in this patient population. Further longitudinal studies are needed to determine whether these associations are causal and the direction of effect.

    Barium enema (BE) examinations for the investigation of suspected colonic disease are often unsuccessful in elderly patients. The purpose of this study was to evaluate the success rate of BE in hospitalized frail elderly patients. Four hundred and seventy-two elderly patients hospitalized for different reasons underwent BE examinations. The medical charts and radiological reports were retrospectively reviewed. One hundred and ninety-two (41%) BE examinations were considered inadequate; mostly (32%) because of inappropriate preparation. Sixty-seven patients (14%) were not cooperative and could not retain the contrast material, and in 25 patients (5%), the examination failed due to both these reasons. The characteristics associated with unsuccessful BE examination were the mean number of medical problems (p < 0.001), the mean number of scheduled medications (p < 0.05) and in particular the long-term use of laxatives (p < 0.01) or antiparkinsonian drugs (p < 0.01). Of great significance in predicting an inadequate BE were the patient's functional status (p < 0.001) and the presence of dementia (p < 0.001). The high percentage of unsuccessful BEs in the frail elderly suggests that clinicians should carefully consider the need for that examination in these patients. We suggest that only in patients where there is a clear suspicion of a bleeding or obstructing tumor should a BE examination be performed, and even in these cases, colonoscopy or CT may be preferable as the initial examination in the frail elderly.

    This study was designed to determine the effect of nandrolone decanonate (ND) on HDL-C, apolipoproteins and paraoxonase (PON) activity in stable hemodialysis patients. 64 hemodialysis patients were treated with ND at a dose of 100 mg/I.M./week for 4 months. HDL-C, Apo-AI, Apo B, concentrations and PON activity were measured before and after 2 and 4 months of treatment as well as 2 months after withdrawing the treatment. After 4 months of treatment, an elevation in the serum levels of Apo B (P<0.0001) and a marked decrease in the concentration of HDL-C (P<0.0001), Apo-AI (P<0.0001) and PON activity (P<0.0001) were found. A significant correlation between PON and both Apo-AI (r=0.270, P<0.04) and HDL-C (r=0.455, P<0.0001) and also between HDL-C and Apo-AI (r=0.305, P<0.02) were found. Results revealed the adverse effects of ND on apolipoprotein levels in our study population. It is possible that ND reduces PON activity mostly by reducing both the HDL-C and Apo-AI levels.

    Hemodialysis (HD) is routinely offered to patients with end-stage renal disease in the United States who are ineligible for other renal replacement modalities. The frequency of HD among the US population is greater than all other countries, except Taiwan and Japan. In US, patients are often dialyzed irrespective of age, comorbidities, prognosis, or decision-making capacity. Determination of when patients can no longer dialyze is variable and can be dialysis-center specific. Determinants may be related to progressive comorbidities and frailty, mobility or access issues, patient self-determination, or an inability to tolerate the treatment safely for any number of reasons (e.g., hypotension, behavioral issues). Behavioral issues may impact the safety of not only patients themselves, but also those around them. In this article the authors present the case of an elderly patient on HD with progressive cognitive impairment and combative behavior placing him and others at risk of physical harm. The authors discuss the medical, ethical, legal, and psychosocial challenges to care of such patients who lack decision-making capacity with a focus on variable approaches by regions and culture. This manuscript provides recommendations and highlights resources to assist nephrologists, dialysis personnel, ethics consultants, and palliative medicine teams in managing such patients to resolve conflict.

    Abstract Background Depression is a prevalent, yet underdiagnosed, psychiatric disorder among patients with end-stage renal disease. Active case identification through routine screening is suggested; however, patient-related barriers may reduce the effectiveness of screening for, and treating, depression. This study aimed to explore the perceived barriers that limit patients from participating in screening and treatment programs for depression. Methods In a cross-sectional study of chronic maintenance hemodialysis patients, the Perceived Barriers to Psychological Treatment questionnaire, adapted to include screening, was used to measure perceived barriers. The two-item Patient Health Questionnaire was used to identify patients with depressive symptoms. Results Of 160 participants, 73.1% reported at least one barrier preventing them from participation [95% confidence interval (95% CI) 66.2–80.0%]. Patients with depressive symptoms were more likely to perceive at least one barrier to a screening program for depression compared with those without depressive symptoms (96% versus 68.9%, respectively; odds ratio = 10.8; 95% CI 1.4–82.8; P = 0.005). The association of the barrier scores with depressive symptoms remained significant after adjustment for patient’s characteristics. The most common barriers that patients expressed were concerns about the side effects of any antidepressant medications that may be prescribed (40%), concerns about having more medications (32%), feeling that the problem is not severe enough (23%) and perceiving no risk of depression (23%). Conclusions Negative perceptions about depression and its treatment among hemodialysis patients constitute an important barrier to identifying this condition and first need to be addressed before implementing a screening program in this population.

    Quality of life (QoL) has become an important issue for patients with chronic renal failure diseases who are permanently undergoing hemodialysis. In this study, an adapted schedule for the evaluation of individual quality of life (SEIQoL-adapted) was used to evaluate QoL among hemodialysis patients, to explore their views about the most important aspects of life satisfaction. A multiple approach design and convenience sampling were applied to recruit 53 patients from a hemodialysis unit in Iran. Data were collected through structured interviews and then analyzed using conventional content analysis. A total score for QoL was calculated using scale guideline. The most important aspects of life were health, family, financial status, living conditions, leisure activities, relationships and socializing, religious and spiritual issues, medical knowledge, and therapies or treatments. The calculated mean QoL score was 66.2, indicating a relatively high life satisfaction. Males had higher QoL scores than females in both married and single groups. Moreover, the relationships between the QoL scores and education, job and marital status were not statistically significant. The SEIQoL-adapted revealed reasonable lay definitions of QoL in a group of patients following chronic renal failure. The patients' views of the aspects of life could be used by health policy makers, clinicians, and caregivers as a reliable guide to the most important priorities for treatment and medical interventions.

    Purpose. To retrospectively review the patency of endovascular interventions with nitinol stent placement for symptomatic central venous occlusions in hemodialysis patients. Methods. A retrospective review of all patients who underwent endovascular interventions for dysfunctional hemodialysis grafts and fistulas was performed from April 2004 to August 2006. A total of 6 patients presented with arm and/or neck and facial swelling and left brachiocephalic vein occlusion. The study group consisted of 3 men and 3 women with a mean age of 79.5 years (SD 11.2 years). Of these 6 patients, 1 had a graft and 5 had fistulas in the left arm.more » The primary indication for nitinol stent placement was technical failure of angioplasty following successful traversal of occluded central venous segments. Patency was assessed from repeat fistulograms and central venograms performed when patients redeveloped symptoms or were referred for access dysfunction determined by the ultrasound dilution technique. No patients were lost to follow-up. Results. Nitinol stent placement to obtain technically successful recanalization of occluded venous segments was initially successful in 5 of 6 patients (83%). In 1 patient, incorrect stent positioning resulted in partial migration to the superior vena cava requiring restenting to prevent further migration. Clinical success was observed in all patients (100%). Over the follow-up period, 2 patients underwent repeat intervention with angioplasty alone. Primary patency was 83.3% (95% CI 0.5-1.2) at 3 months, and 66.7% at 6 and 12 months (0.2-1.1, 0.1-1.2). Secondary patency was 100% at 12 months with 3 patients censored over that time period. Mean primary patency was 10.4 months with a mean follow-up of 12.4 months. No complications related to recanalization of the occluded central venous segments were observed. Conclusion. Our initial experience has demonstrated that use of nitinol stents for central venous occlusion in hemodialysis patients is

    While there is a recognized risk of hepatitis C acquisition associated with dialysis away from the "home" center, there is little documented data on the effect that dialysis while traveling has on the dialysis patient's health. This study was designed to examine the incidence of travel within a hemodialysis population and to ascertain whether travel was associated with morbidity for patients on hemodialysis. Travel data were collected prospectively over a 6-month period, from April 2009, for all patients receiving maintenance hemodialysis across our dialysis centers. Biochemical, microbiological, and hematological parameters as well as hepatitis serology and antibiotic starts were recorded for 12 weeks prior to and following dialysis away from center. A total of 172 individuals traveled on 200 occasions. The blood stream infection rate for travelers with a central venous catheter was 0.25 versus 0.83/1,000 access days (p = 0.038) in the 12 weeks pre-travel versus post-travel. Parenteral and oral antibiotic starts were both significantly elevated post-travel and were mainly instituted for either chest or urinary sepsis. There was evidence of raised inflammatory markers and anemia on return to center but no evidence of hepatitis B or hepatitis C seroconversion. Travel and dialysis away from a patient's usual hemodialysis unit is a common occurrence but is associated with an increased risk of bacterial infection, anemia, and inflammatory response. This study provides evidence for the concern that hemodialysis away from center is associated with increased morbidity. © 2014 International Society of Travel Medicine.

    Symptomatic hypotension is the most frequent acute complication affecting patients during chronic hemodialysis treatment sessions. Many reports have demonstrated that the use of cool dialysate has a protective effect on blood pressure during hemodialysis treatments. In the present study, we investigated whether preventing the hyperthermic response had favourable effects on hemodynamic stability during the hemodialysis procedure while affording good tolerance to patients. We investigated the effect of thermal control of dialysate on hemodynamic stability in hypotension-prone patients in our center. Patients were eligible for the study if they had symptomatic hypotensive episodes (> 3/12session/ month) during the screening phase. The study was designed with two phases for the same selected patients and two treatment arms, each phase lasting 4 weeks. In the first phase, we adjusted dialysate temperature on 36 masculineC for 12 sessions (cold dialysis) and in the second phase we used a device allowing the regulation of thermal balance (Blood Temperature Monitor; Fresenius Medical Care, Bad Homberg, Germany), that keep body temperature unchanged (isothermic dialysis). Nine HD patients were enrolled and completed the study. During the screening phase the mean ultrafiltration was 4 1% of dry weight, and blood pressure decreased from 9916 to 8016 mm Hg (p<0.001). In 5.01.7 sessions of 12 treatments were complicated by hypotension. In the first and second phase we observed a decrease of complicated treatments with symptomatic hypotension (5.01.7 versus 2.71.6 y 2.81.7; p<0.01). Both procedures: Cold dialysis and Isothermic dialysis was well tolerated by patients. Results show that active control of body temperature can significantly improve intradialytic tolerance in hypotension-prone patients.

    Background Little is known about acute hemodialysis in the US. Here we describe predictors of receipt of acute hemodialysis in one state and estimate the marginal impact of acute hemodialysis on survival after accounting for confounding due to illness severity. Materials and Methods This is a retrospective cohort study of acute-care hospitalizations in Pennsylvania from October 2005 to December 2007 using data from the Pennsylvania Health Care Cost Containment Council. Exposure variable is acute hemodialysis; dependent variable is survival following acute hemodialysis. We used multivariable logistic regression to determine propensity to receive acute hemodialysis and then, for a Cox proportional hazards model, matched acute hemodialysis and non-acute hemodialysis patients 1∶5 on this propensity. Results In 2,131,248 admissions of adults without end-stage renal disease, there were 6,657 instances of acute hemodialysis. In analyses adjusted for predicted probability of death upon admission plus other covariates and stratified on age, being male, black, and insured were independent predictors of receipt of acute hemodialysis. One-year post-admission mortality was 43% for those receiving acute hemodialysis, compared to 13% among those not receiving acute hemodialysis. After matching on propensity to receive acute hemodialysis and adjusting for predicted probability of death upon admission, patients who received acute hemodialysis had a higher risk of death than patients who did not over at least 1 year of follow-up (hazard ratio 1·82, 95% confidence interval 1·68–1·97). Conclusions In a populous US state, receipt of acute hemodialysis varied by age, sex, race, and insurance status even after adjustment for illness severity. In a comparison of patients with similar propensity to receive acute hemodialysis, those who did receive it were less likely to survive than those who did not. These findings raise questions about reasons for lack of benefit. PMID:25141028

    Oral baclofen toxicity is extremely rare, but can affect patients with renal disease due to the drug's predominant renal clearance of approximately 69-85%. Patients with severely impaired renal function typically develop symptoms soon after initiating baclofen therapy, even at relatively low doses. A 69-year-old woman with a history of hemodialysis-dependent end-stage renal disease presented to the Emergency Department with encephalopathy, ataxia, and dystonia after the addition of a recent baclofen prescription for back pain (10 mg twice daily). She had been taking baclofen as prescribed for approximately 1 week when, the day prior to admission, she had increased her dose to a total of 40 mg. Diagnostic studies demonstrated the patient had chronic, end-stage renal disease and a supratherapeutic concentration of baclofen. Signs and symptoms resolved with hemodialysis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: It is of critical importance for emergency physicians to appreciate impaired baclofen clearance in those with underlying renal disease to obviate the potential for significant drug toxicity.

    Vitamin B6 deficiency is common in hemodialysis patients and may contribute to anemia and abnormal bone metabolism in this population. 6-month, open-label, randomized controlled parallel-group study in hemodialysis centers. Fifty-six maintenance hemodialysis patients with relatively high resistance to erythropoiesis-stimulating agents (ESA). Intravenous vitamin B6 (60 mg of intravenous pyridoxal 5'-phosphate after each thrice-weekly hemodialysis session). The primary and secondary outcomes were changes over time in ESA resistance index and bone turnover markers, respectively. The prevalence of vitamin B6 deficiency was 40% overall. Compared with the control group, the B6 group showed an upward change in ESA resistance index over time (P interaction  = .038). At week 13 (a priori-defined time point), pyridoxal 5'-phosphate administration was associated with higher ESA resistance index by 0.97 (95% confidence interval, 0.02-1.92) ×10 -2  μg ⋅darbepoetin-α/kg per g/dL⋅hemoglobin after baseline adjustment, which was not modified by baseline vitamin B6 status. There was a trend toward increase in serum erythropoietin concentrations in the B6 group after adjustment for baseline values, hemoglobin, and weekly ESA dose (P interaction  = .06). The downward changes of bone-specific alkaline phosphatase and tartrate-resistant acid phosphatase 5b in the B6 group relative to the control group were pronounced in patients without vitamin B6 deficiency (P interaction < .001 and .017, respectively), despite nonsignificant between-group difference in 1-84 parathyroid hormone. Thrice-weekly intravenous vitamin B6 (60 mg pyridoxal 5'-phosphate hydrate) worsens the response to ESA and may blunt the response of bone to parathyroid hormone in hemodialysis patients.

    Exercise training during hemodialysis has been found to improve functional capacity, nutritional status, cardiovascular risk factors, depression, and well being in hemodialysis patients. This report describes a nursing experience that applied exercise training to improve activity intolerance, powerlessness, and ineffective health maintenance in a hemodialysis patient. The care period was from May 11 to July 27, 2012. The author collected information using observation, interview, physical examination, and medical record review and identified patient care problems including activity intolerance, powerlessness, and ineffective health maintenance. In addition to providing individual nursing interventions, the author designed a stationary bicycle installed at the end of the bed. The patient was asked use the bicycle to exercise 30 mins per time, three times per week for a period of 12 weeks during the patient's hemodialysis period. Before and after a 12-week of exercise training, collected the 6-minute walk test (6MWT), self-perceived improvement, and self-reported depression scales were performed prior to and after completion of the intervention. Hematological triglyceride, albumin, and hemoglobin data were collected each week. Heart rate, blood pressure, and oxygen saturation were examined prior to and after the intervention to ensure patient safety. After the 12-week intervention, the average heart rate achieved 40-60% of the maximum heart rate and the heart rate peaked between 85 and 121 bpm. Moreover, the 6MWT distance increased from 210 m to 255 m, triglyceride decreased from 622 mg/dL to 173 mg/dL, and self-perceived fatigue and depression markedly improved. This nursing experience is shared with nurses caring for patients with similar conditions.

    The aim of our study was to evaluate the function and growth of parathyroid tissue autografted into the forearm of hemodialysis patients using several presently available methods. In a dynamic study, the secretory function of autografted tissue was evaluated in seven patients using either zero calcium dialysate or calcium infusion. In an additional prospective study, seven patients had repeated determinations of plasma immunoreactive parathyroid hormone (iPTH) concentration on samples from both forearms, a radionuclide evaluation of autograft function using thallium-201 chloride, and real time ultrasonography. Light microscopy analysis was performed in two patients. The dynamic study demonstrated that induction ofmore » hypocalcemia was followed by an increase, and induction of hypercalcemia by a decrease in circulating iPTH in both forearms using three different radioimmunoassays similar to what has been reported for normal parathyroid tissue. A significant gradient (ie, greater than 2.0) of plasma iPTH concentration in samples from both forearms was observed in only three out of the seven patients of the prospective study. Two of these patients disclosed an increased uptake of /sup 201/TI chloride at the site of autografted tissue and had an echographically detectable mass. In both, hyperplastic parathyroid tissue was removed. At present, the remaining third patient does not have other features of recurrent hyperparathyroidism. In conclusion, autotransplanted parathyroid tissue of hemodialysis patients shows an adequate response to physiologic stimuli such as hypo- and hypercalcemia. Dynamic tests, therefore, appear to be a useful tool in the assessment of its function. In addition, radionuclide and echographic studies may be reliable adjuncts in the detection of marked parathyroid autograft hyperplasia.« less

    Quality of life is one of the parameters to check the improvement of hemodialysis treatment among hemodialysed patients. Those patients will be dealing with this treatment in long term if this treatment is the only way for them to replace their kidney function and this thing will affect their quality of life. To evaluate the quality of life patients on hemodialysis using kidney disease quality of life-short term 24 (KDQoL-SF24) Malaysian Version. Cohort observational study was conducted in this study. The study included 78 hemodialysed patients in HD center Penang, Malaysia. There were 9 components which had the lower of the mean and standard deviation (SD) than the standard form; work status (15.01 ± 35.57), cognitive function (75.66 ± 13.75), quality of life social interaction (76.32 ± 16.11), sleep (55.86 ± 15.30), social support (59.61 ± 22.08), patient satisfaction (43.24 ± 15.32), physical functioning (50.06 ± 42.81), general health (29.62 ± 25.56), and role emotional (54.27 ± 49.92). In this HD center, the group of patient's age who had the lower mean ± SD from the KDQoL-SF Manual Standard were the first and the sixth groups of patient's age (≤20 and 61-70). The study conducted in HD center, Penang, Malaysia showed that the scoring of work status, cognitive function, quality of social interaction, sleep, social support, patient satisfaction, physical functioning, general health, and role emotional were low than standard form.

    Whether the duration of hemodialysis treatments improves outcomes remains controversial. Here, we evaluated survival and clinical changes associated with converting from conventional hemodialysis (mean=3.75 h/treatment) to in-center nocturnal hemodialysis (mean=7.85 h/treatment). All 959 consecutive patients who initiated nocturnal hemodialysis for the first time in 77 Fresenius Medical Care facilities during 2006 and 2007 were eligible. We used Cox models to compare risk for mortality during 2 years of follow-up in a 1:3 propensity score–matched cohort of 746 nocturnal and 2062 control patients on conventional hemodialysis. Two-year mortality was 19% among nocturnal hemodialysis patients compared with 27% among conventional patients. Nocturnal hemodialysis associated with a 25% reduction in the risk for death after adjustment for age, body mass index, and dialysis vintage (hazard ratio=0.75, 95% confidence interval=0.61–0.91, P=0.004). With respect to clinical features, interdialytic weight gain, albumin, hemoglobin, dialysis dose, and calcium increased on nocturnal therapy, whereas postdialysis weight, predialysis systolic blood pressure, ultrafiltration rate, phosphorus, and white blood cell count declined (all P<0.001). In summary, notwithstanding the possibility of residual selection bias, conversion to treatment with nocturnal hemodialysis associates with favorable clinical features, laboratory biomarkers, and improved survival compared with propensity score–matched controls. The potential impact of extended treatment time on clinical outcomes while maintaining a three times per week hemodialysis schedule requires evaluation in future clinical trials. PMID:22362905

    The aim of this prospective study was to evaluate long-term effects of arteriovenous fistula (AVF) on the development of pulmonary arterial hypertension (PAH) and the relationship between blood flow rate of AVF and pulmonary artery pressure (PAP) in the patients with end-stage renal disease (ESRD). This prospective study was performed in 20 patients with ESRD. Before an AVF was surgically created for hemodialysis, the patients were evaluated by echocardiography. Then, an AVF was surgically created in all patients. After mean 23.50 ± 2.25 months, the second evaluation was performed by echocardiography. Also, the blood flow rate of AVF was measured at the second echocardiographic evaluation. Pulmonary arterial hypertension was defined as a systolic PAP above 35 mmHg at rest. Mean age of 20 patients with ESRD was 55.05 ± 13.64 years; 11 of 20 patients were males. Pulmonary arterial hypertension was detected in 6 (30%) patients before AVF creation and in 4 (20%) patients after AVF creation. Systolic PAP value was meaningfully lower after AVF creation than before AVF creation (29.95 ± 10.26 mmHg vs. 35.35 ± 7.86 mmHg, respectively, P: 0.047). However, there was no significant difference between 2 time periods in terms of presence of PAH (P>0.05). Pulmonary artery pressure did not correlate with blood flow rate of AVF and duration after AVF creation (P>0.05). In hemodialysis patients, a surgically created AVF has no significant effect on the development of PAH within a long-term period. Similarly, blood flow rate of AVF also did not affect remarkably systolic PAP within the long-term period. © 2010 The Authors.

    PurposeWe report our institutional experience with sharp central venous recanalization in chronic hemodialysis patients who failed standard techniques.Materials and MethodsSince January 2014, a series of seven consecutive patients (four males and three females), mean age 35 years (18–65 years), underwent sharp central venous recanalization. Indications included obtaining hemodialysis access (n = 6) and restoration of superior vena cava (SVC) patency to alleviate occlusion symptoms and restore fistula function (n = 1). The transseptal needle was used for sharp recanalization in six patients, while it could not be introduced in one patient due to total occlusion of the inferior vena cava. Instead, transmediastinal SVC access using Chibamore » needle was obtained.ResultsTechnical success was achieved in all cases. SVC recanalization achieved symptoms’ relief and restored fistula function in the symptomatic patient. One patient underwent arteriovenous fistula creation on the recanalized side 3 months after the procedure. The remaining catheters were functional at median follow-up time of 9 months (1–14 months). Two major complications occurred including a right hemothorax and a small hemopericardium, which were managed by covered stent placement across the perforated SVC.ConclusionSharp central venous recanalization using the transseptal needle is feasible technique in patients who failed standard recanalization procedures. The potential high risk of complications necessitates thorough awareness of anatomy and proper technical preparedness.« less

    Hyperphosphoremia is one of the most important risk factors for morbidity and mortality for chronic kidney disease (CKD) patients, and also, for the general population. Excessive dietary intake of phosphate (P) is one of the key factors. In particular, P in its inorganic form, which is contained in food additives, is more readily absorbed. Unfortunately, these food additives are mostly present in convenience so called "fast foods" (pre-cooked), soft drinks, which represent the typical food consumed by our hemodialysis (HD) population, composed by elderly people, mostly low-socio economic class, who often live alone. We performed an observational retrospective multicenter study to find any association between social, cultural and economic situation, as well as food habits, and P levels in a cohort of patients on HD. Secondarily; we also examined the association between the fast food consumption and increased P levels, as well as patient compliance for P binding products. To explore the association between socio-economic factors and serum P levels, we enrolled 100 patients on periodic HD treatment from three different units. Information on social, cultural, economic, diet habits, therapy for hyperphosphoremia and hematological and clinical parameters had been collected through specific questionnaires, administered by a physician. Results showed serum P level was reduced in patients who live alone compared to patients in family (P = 0.04), in self-sufficient (P = 0.05) and in patients belonging to middle-upper class, versus low-class (P = 0.003). Fast foods intake correlates with increase in P serum levels (P = 0.002), whilst the same correlation was not found for cheese intake. Our data show that socio-economic status and food habits are useful predictors of P serum levels. In conclusion, dietary counseling of patients on HD is mandatory. Interventions that consider the socio-economic situation allow delivering important messages on foods with the least amount of P

    D-penicillamine and its major metabolites cysteine-penicillamine disulphide (CP) and penicillamine disulphide (P2) concentrations were measured in plasma from a hemodialysis patient with rheumatoid arthritis. CP and P2 alone were measured in plasma and a plasma ultrafiltrate from a second patient. On penicillamine 250 mg thrice weekly taken after dialysis pre-dialysis penicillamine concentrations were in the range 5.9-9.9 mumol/l. CP and P2 concentrations remained stable (range 139-197 mumol/l and 10-20 mumol/l) over 5 weeks and were of the same order as previously found in patients with normal renal function on higher doses of the drug. On penicillamine 250 mg daily concentrations of metabolites CP and P2 reach 193 mumol/l and 59.2 mumol/l after 2 and 3 weeks respectively. Concentration of metabolites fell by about half and of penicillamine by about a third after dialysis. Concentration of metabolites in ultrafiltrate were on average 75% lower than in plasma. Penicillamine 250 mg thrice weekly given after dialysis appears to be an appropriate dose for hemodialysis patients with rheumatoid arthritis.

    Bone deformities and fractures are common consequences of renal osteodystrophy in the dialysis population. Persistent hypophosphatemia may be observed with more frequent home hemodialysis regimens, but the specific effects on the skeleton are unknown. We present a patient with end-stage renal disease treated with frequent home hemodialysis who developed severe bone pain and multiple fractures, including a hip fracture and a tibia-fibula fracture complicated by nonunion, rendering her nonambulatory and wheelchair bound for more than a year. A bone biopsy revealed severe osteomalacia, likely secondary to chronic hypophosphatemia and hypocalcemia. Treatment changes included the addition of phosphate to the dialysate, a higher dialysate calcium concentration, and increased calcitriol dose. Several months later, the patient no longer required a wheelchair and was able to ambulate without pain. Repeat bone biopsy revealed marked improvements in bone mineralization and turnover parameters. Also, with increased dialysate phosphate and calcium concentrations, as well as increased calcitriol, circulating fibroblast growth factor 23 levels increased.

    Hyperphosphatemia in chronic hemodialysis patients is usually treated with aluminium containing phosphate binders. In recent years there has been increasing evidence of serious complications due to aluminium accumulation. We have investigated a new calcium carbonate preparation with an HCl-resistant capsule designed to prevent gastrointestinal side effects. Its phosphate binding capacity in comparison to aluminium chloride hydroxide was investigated in 17 chronic hemodialysis patients. The dose of the phosphate binder was adjusted regularly so that the serum phosphorus levels were below 1.8 mmol/l. The mean dose of aluminium chloride hydroxide was 3.36 g/day and of calcium carbonate 4.96 g/day. The mean (+/- SD) serum calcium level was 2.58 +/- 0.11 mmol/l under aluminium chloride hydroxide and 2.50 +/- 0.25 mmol/l under calcium carbonate. The mean phosphorus level was 1.69 +/- 0.31 mmol/l under aluminium chloride hydroxide and 1.71 +/- 0.33 under calcium carbonate. Serum aluminium fell from 64.5 +/- 14.4 micrograms/l to 28.5 +/- 17.5 micrograms/l after 3 months.

  19. Methemoglobinemia in critically ill patients during extended hemodialysis and simultaneous disinfection of the hospital water supply

    2009-01-01

    Introduction To evaluate the cause of methemoglobinemia in patients undergoing extended daily hemodialysis/hemodiafiltration we analyzed the relationship between methemoglobinemia and the water disinfection schedule of the hospital. Methods We reviewed all arterial blood gas analyses, obtained over a one-year period, in patients undergoing extended hemodialysis/hemodiafiltration, and compared the methemoglobin concentrations obtained on the days when the water supply was disinfected, using a hydrogen peroxide/silver ion preparation, with data measured on disinfection-free days. Results The evaluation of 706 measurements revealed a maximum methemoglobin fraction of 1.0 (0.8; 1.2) % (median and 25th; 75th percentiles) during hemodialysis/hemodiafiltration on the disinfection-free days. The methemoglobin fraction increased to 5.9 (1.3; 8.4) % with a maximal value of 12.2% on the days of water disinfection (P < 0.001 compared to disinfection-free days). Spot checks on hydrogen peroxide concentrations in the water supply, the permeate, and the dialysate, using a semi-quantitative test, demonstrated levels between 10 and 25 mg/l during water disinfection. Conclusions Our results demonstrate that even a regular hospital water disinfection technique can be associated with significant methemoglobinemia during extended hemodialysis. Clinicians should be aware of this potential hazard. PMID:19821985

    The relationship between smoking and mortality in patients on hemodialysis is controversial. Earlier studies showed that the insertion/deletion (I/D) polymorphism of the ACE gene might have an effect on mortality. The aim of this study was to test the impact of smoking on survival and whether this association was influenced by ACE gene I/D polymorphism in patients on maintenance hemodialysis. In this prospective, multicenter cohort study we analyzed 709 prevalent patients on maintenance hemodialysis. Patients were allocated into groups based on their smoking habit. Outcome data were collected during the 144-month follow-up period. Outcomes of current smokers and lifelong non-smokers were compared. In order to control for interactions between predictor variables, we also identified 160 matched pairs for further sub-analysis. The vast majority of patients (67%) were non-smokers, followed by current smokers (22.2%) and ex-smokers (9.8%). Smoking had no impact on survival in the matched pair analysis ( p = 0.99). After adjustment for ACE I/D polymorphism and other co-variates, smoking had no effect on survival. Our data suggest that smoking has no impact on survival; neither is it associated with ACE gene I/D polymorphism in hemodialysis patients.

    Background Poor sleep quality is a common, persistent, and important problem to patients with end-stage renal disease (ESRD). This report examines whether sleep quality is associated with dialysis treatment factors and other modifiable clinical factors in a large group of hemodialysis (HD) patients. Methods Cross-sectional analyses were conducted on baseline data collected from participants in the Frequent Hemodialysis Network trials. Sleep quality was measured using the Medical Outcomes Study Sleep Problems Index II (SPI II), a 9-item measure of sleep quality with higher scores reflecting poorer sleep quality. Results The participants had an age of 51.2 ± 13.6 years, 61% were male, 38% were black, and 42% had diabetes. Higher pre-dialysis serum phosphorus (per 0.5 mg/ml) (OR 0.91; 95% CI 0.85, 0.96) and depression (OR 0.16; 95% CI 0.10, 0.25) were independently associated with decrements in sleep quality. There was also a difference in time to recovery from dialysis for the fourth versus the first SPI II quartile (5.1 h; p < 0.0001). Conclusion These findings underscore the link between sleep and daytime function and suggest that improving sleep may provide an opportunity to improve outcomes in ESRD. Whether sleep problems may be improved by reduction of serum phosphorus or treatment of depression in the HD population merits further investigation. PMID:21474924

    Clinically, the ankle-brachial blood pressure index (ABI) and skin perfusion pressure (SPP) are used to screen for subclinical peripheral artery disease. However, the association between the SPP and mortality in hemodialysis patients has not been previously reported. We investigated these factors and compared the ABI and SPP in patients receiving hemodialysis. A total of 102 patients receiving maintenance hemodialysis were enrolled in this study. The ABI was determined using an ABI-form (Colin, Japan). The SPP was measured using a SensiLase(TM) PAD3000 (Kaneka, Osaka, Japan). The mean follow-up period was 3.2 ± 1.4 years. A multivariate Cox analysis identified a low ABI (p=0.019) and a low SPP (p=0.047) as being independent predictors of mortality. A receiver operating characteristic (ROC) analysis of the ABI revealed a cutoff point of 1.1 and an area under the curve (AUC) of 0.79, with a sensitivity of 90% and a specificity of 62%. A ROC analysis of the SPP revealed a cutoff point of 54.0 mmHg and an AUC of 0.71, with a sensitivity of 55% and a specificity of 84%. Both low ABI and SPP values were found to be independent risk factors for mortality among hemodialysis patients. The cutoff point for ABI as a predictor of mortality was 1.1, while that for SPP was 54.0 mmHg.

    Summary Background and objectives There are conflicting research results about the survival differences between hemodialysis and peritoneal dialysis, especially during the first 2 years of dialysis treatment. Given the challenges of conducting randomized trials, differential rates of modality switch and transplantation, and time-varying confounding in cohort data during the first years of dialysis treatment, use of novel analytical techniques in observational cohorts can help examine the peritoneal dialysis versus hemodialysis survival discrepancy. Design, setting, participants, & measurements This study examined a cohort of incident dialysis patients who initiated dialysis in DaVita dialysis facilities between July of 2001 and June of 2004 and were followed for 24 months. This study used the causal modeling technique of marginal structural models to examine the survival differences between peritoneal dialysis and hemodialysis over the first 24 months, accounting for modality change, differential transplantation rates, and detailed time-varying laboratory measurements. Results On dialysis treatment day 90, there were 23,718 incident dialysis—22,360 hemodialysis and 1,358 peritoneal dialysis—patients. Incident peritoneal dialysis patients were younger, had fewer comorbidities, and were nine and three times more likely to switch dialysis modality and receive kidney transplantation over the 2-year period, respectively, compared with hemodialysis patients. In marginal structural models analyses, peritoneal dialysis was associated with persistently greater survival independent of the known confounders, including dialysis modality switch and transplant censorship (i.e., death hazard ratio of 0.52 [95% confidence limit 0.34–0.80]). Conclusions Peritoneal dialysis seems to be associated with 48% lower mortality than hemodialysis over the first 2 years of dialysis therapy independent of modality switches or differential transplantation rates.

    Patients on chronic hemodialysis often have acquired coagulopathy that can aggravate bleeding from puncture site after needle extraction. Chitosan-based pads have been reported to accelerate hemostasis even in the presence of coagulopathy. The aim of this study was to evaluate the hemostatic efficacy of the chitosan pads compared to gauze pads, applied for local hemostasis. A crossover study in a cohort of patients on hemodialysis with extended time to hemostasis after needle extraction. At the end of each dialysis, either gauze or chitosan pad was applied on both access points (arterial and venous). The type of pad was changed in the next dialysis all together 5 times in each patient (10 applications per patient for every pad). A total of 288 applications, 144 for each type of pad, were performed in 15 patients. The average time to hemostasis for the entire group was significantly shorter with the chitosan pads compared to the regular gauze pads ("arterial" point 3 vs. 18.5 min, p<0.001 "venous" access 2.8 vs. 13.2 min, p<0.001, respectively). Chitosan pads significantly reduce time to hemostasis and should be considered for the treatment of accessible bleeds in patients with coagulopathy.

    We aimed to evaluate the efficacy of Lachance formula and more readily available clinical or laboratory factors (other than serum methanol level) in prediction of the needed time for hemodialysis in methanol-poisoned patients. In a retrospective study, all methanol-poisoned patients referred to us between March 2008 and March 2016 were enrolled. The patients' demographic characteristics, on-arrival vital signs, signs/symptoms, and laboratory tests were evaluated for factors that could prognosticate the dialysis duration. Of 72 patients enrolled, 54 underwent hemodialysis once (group 1) and 18 needed more than one session of hemodialysis (group 2). All were treated by ethanol, bicarbonate, and leucovorin. Lachance formula overestimated the patients in higher methanol levels and underestimated them in lower methanol levels. It properly predicted the needed time for hemodialysis when the methanol level was between 15 and 25 mg/dL. Groups 1 and 2 were different in terms of their ingested alcohol dose (P = 0.001), creatinine (P = 0.02), dyspnea on presentation (P = 0.002), and the place they had been dialyzed (P = 0.013). Dialysis duration significantly correlated with dyspnea on presentation (P = 0.028) and ingested alcohol dose (P = 0.02). After performance of logistic regression analysis, only creatinine was statistically significantly different between the two groups (P = 0.02). Median creatinine levels were 1.3 [1, 6] (0.8-2.7) and 1.4 [1.35, 2.1] (0.8-6.5) in the patients who were dialyzed once and twice, respectively. As a conclusion, creatinine is possibly a readily available test that can predict the appropriate time needed for hemodialysis in methanol-poisoned patients.

    It is well established that nutritional status is an important factor affecting the outcome and recovery from disease or injury. Assessment of nutritional status is an integral part of care for patients with chronic kidney disease, especially for those treated with dialysis procedures. According to available literature, 18%-80% of patients on dialysis have some form of nutritional deficiency. Furthermore, in patients treated with dialysis procedures there is a rule called 'reverse epidemiology', according which patients with better nutritional status have better survival rate. Therefore, nutritional assessment should detect malnutrition and rate the overall nutritional status of each patient through clinical data categories: medical history, physical examination, nutrition physical examination, psychosocial history, demographics, physical activity, and current medical/surgical issues. Consequently, the main aim of our study was to analyze the nutritional status of our patients treated with hemodialysis procedures. Another aim was to analyze the applicability of measuring skinfold by caliper as a method of nutritional status assessment. During a six-month period, we analyzed 129 patients (57.4% of men and 42.6% of women), mean age 68.1 ± 12.4 years, treated with hemodialysis procedures (24.8% of patients were treated with online hemodiafiltration and 75.2% with standard, conventional hemodialysis) as the method of choice of renal replacement therapy (RRT) for more than 6 months. All patients were dialyzed three times a week for four hours on biocompatible synthetic membranes. The patients treated with online hemodiafiltration were dialyzed on high-flux helixone membranes, while those treated with standard, conventional hemodialysis were dialyzed on polysulfone membranes and helixone low-flux membranes. The mean time of RRT was 71.2 ± 56.7 months. During the study period, in each patient we followed medical history, and clinical and laboratory parameters of

    Objectives To quantify the prevalence of frailty in adult patients of all ages undergoing chronic hemodialysis, its relationship to comorbidity and disability, and its association with adverse outcomes of mortality and hospitalization. Design Prospective cohort study. Setting Single hemodialysis center in Baltimore, Maryland. Participants 146 prevalent hemodialysis patients enrolled between January 2009 and March 2010 and followed through August 2012. Measurements Frailty, comorbidity, and disability on enrollment into the study and subsequent mortality and hospitalizations. Results At enrollment, 50.0% of older (age≥65) and 35.4% of younger (age<65) hemodialysis patients were frail; 35.9% and 29.3% were intermediately frail, respectively. The 3-year mortality was 16.2% for non frail, 34.4% for intermediately frail, and 40.2% for frail participants. Intermediate frailty and frailty were associated with a 2.68-fold (95% CI: 1.02-7.07, P=0.046) and 2.60-fold (95%CI: 1.04-6.49, P=0.041) higher risk of death independent of age, sex, comorbidity, and disability. In the year after enrollment, median number of hospitalizations was 1 (IQR 0-3). The proportion with 2 or more hospitalizations was 28.2% for non frail, 25.5% for intermediately frail, and 42.6% for frail participants. While intermediate frailty was not associated with the number of hospitalizations (RR=0.76, 95%CI:0.49-1.16, P=0.21), frailty was associated with a 1.43-fold (95%CI:1.00-2.03, P=0.049) higher number of hospitalizations independent of age, sex, comorbidity, and disability. The association of frailty with mortality and hospitalizations did not differ between older and younger participants (Interaction P=0.64 and P=0.14, respectively). Conclusions Adults of all ages undergoing hemodialysis have a very high prevalence of frailty, more than 5-fold higher than community dwelling older adults. In this population, regardless of age, frailtyis a strong, independent predictor of mortality and number of

    Autosomal Dominant Polycystic Kidney Disease (ADPKD) is one of the most common monogenic disorders and the leading inheritable cause of end-stage renal disease worldwide. Cystic and noncystic extrarenal manifestations are correlated with variable clinical presentations so that an inherited disorder is now considered a systemic disease. Kidney and liver cystic infections are the most common infectious complications in ADPKD patients. Furthermore, it is well known that ADPKD is commonly associated with colonic diverticular disease which recently has been reported to be linked to increased risk of infection on hemodialysis patients. Herein, we present a case of anterior abdominal wall abscess caused by Enterococcus faecalis in a patient with ADPKD undergoing hemodialysis. Although the precise pathway of infection remains uncertain, the previous medical history as well as the clinical course of our patient led us to hypothesize an alternative route of infection from the gastrointestinal tract through an aberrant intestinal barrier into the bloodstream and eventually to an atypical location.

    Children undergoing chronic hemodialysis are at risk of cardiovascular disease and often develop left ventricular hypertrophy (LVH). Twenty-four-hour ambulatory blood pressure monitoring (ABPM) is known to better predict cardiovascular morbidity than casual blood pressure (BP) measurement. Given the BP variability attributed to interdialytic fluid overload, 44-h ABPM should better delineate cardiovascular morbidity in pediatric hemodialysis patients. In this cross-sectional study, 17 children (16.7 ± 2.9 years) on chronic hemodialysis underwent 44-h interdialytic ABPM and routine echocardiogram. Left ventricular mass index (LVMI) was calculated by height-based equation; LVH was defined as an LVMI in the ≥95th percentile for height-age and gender. Hypertension was defined by the recommendations of the Fourth Report of the National High Blood Pressure Education Program for casual measurements, and by those of the American Heart Association for ABPM. Twenty-four percentage of patients were hypertensive by casual post-dialytic systolic BP, whereas 59% were hypertensive by ABPM. Eighty-eight percentage of patients had abnormal cardiac geometry: 53% had LVH. Thirty-five percentage (6 of 17) had masked hypertension, including four with abnormal cardiac geometry, of which, three had LVH. LVMI correlated with ABPM, but not with casual measurements. Strongest correlations with an increased LVMI were with 44-h diastolic BP: at night (r = 0.53, P = 0.03) and total load (r = 0.57, P = 0.02). LVH was similarly associated with 44-h nighttime BP: systolic (P = 0.02), diastolic (P = 0.01) and mean arterial (P = 0.01). Casual BP measurement underestimates hypertension in pediatric hemodialysis patients and does not correlate well with indicators of cardiovascular morbidity. In contrast, 44-h interdialytic ABPM better characterizes hypertension, with nighttime parameters most strongly predicting increased LVMI and LVH.

    Background:Despite the high levels of inflammation in hemodialysis patients and the effects of diet on systemic inflammation, such as the development of atherosclerosis and cardiovascular disease, few studies have evaluated the relationship of macronutrients and antioxidants intake with serum C-reactive protein (CRP). Therefore, this study assessed the relationship between serum high sensitivity CRP (hs-CRP) with macronutrients and antioxidants intake and serum albumin. Methods:This cross-sectional study used census sampling to select 75 hemodialysis patients (35 men and 40 women) who attended the hemodialysis department of Vaseie Hospital of Sabzevar, Iran. After obtaining the written consent, all the patients were interviewed and dietary data was collected by using a semi-quantitative food frequency questionnaire including 160 food items. Diet analysis was performed with Nutritionist IV. Before being connected to the dialysis machine, 5 cc fasting blood samples were obtained from all participants and serum hs-CRP and albumin levels were measured. All the statistical analyses were conducted with SPSS -for Windows, version 16.0. Results:The patients’ mean body mass index was 20.09 ± 3.27 kg/ m2. The participants’ intake of antioxidants and all macronutrients, except for carbohydrates and proteins, was less than the standard levels. Moreover, the hs-CRP had significant inverse relationships with serum albumin (P=0.0001) and vitamin E and C intakes but was not significant. Also, a significant relationship was observed between hs-CRP levels and the intake of energy (P=0.002) and protein (P=0.0001). Conclusion:Our findings indicated hs-CRP levels of hemodialysis patients to have significant inverse relationships with serum albumin and vitamin E and C intakes but was not significant. Also, a significant relationship was observed between hs-CRP levels and the intake of energy and protein. PMID:28255396

    To report on the influence of hemodialysis on the disposition of leflunomide in a woman with end-stage renal disease. A 65-year-old white woman with a history of diabetes, end-stage renal disease, rheumatoid arthritis, vasculitis, and leg ulcers was admitted to the hospital with a flare in the symptoms of joint pain and vasculitis. Prior to admission, she had been treated for rheumatoid arthritis with methotrexate 7.5 mg once a week. Due to adverse effects from methotrexate and continuing painful joints, leflunomide was considered as a therapeutic alternative. A loading dose of 100 mg was followed two days later by a daily dose of 10 mg. The active metabolite of leflunomide (A771726) was measured before and after hemodialysis and between hemodialysis sessions over a period of 80 days. Pre- and post-hemodialysis concentrations were compared for 17 sessions during this time. Based on the initial measured concentrations, the leflunomide dose was increased to 20 mg/d for several weeks before being reduced to 15 mg due to elevated liver enzymes. Although renal pathways are responsible in part for excretion of A771726, the concentrations achieved in this patient at doses of 10-20 mg/d were at the low end of the range reported in the literature. It was shown that pre- and post-hemodialysis concentrations of A771726 did not differ significantly. Thus, the low concentrations of A771726 were not a result of the hemodialysis. Steady-state concentrations of A771726 in plasma were not affected by hemodialysis or renal impairment. Reduction of the dose of leflunomide in patients with chronic renal failure undergoing hemodialysis does not appear to be required.

    Restless leg syndrome (RLS) is a common problem in patients with chronic renal failure. It can reduce the quality of life and sleep disturbances. This disorder is usually treated pharmacologically. Recently, complementary medicine methods have been suggested because of chemical drugs adverse effects. There is not enough evidence about the effect of aromatherapy on RLS. The aim of this study was to determine the effects of massage with lavender oil on RLS symptoms in hemodialysis patients. This randomized clinical trial study included 70 hemodialysis patients with RLS that were randomly assigned into two groups in 2014. The experimental group received effleurage massage using lavender oil and control group received routine care for three weeks. Data was collected with RLS questionnaire and analyzed using independent and paired t-test and Chi-square test. The mean RLS scores were not significantly different in the two groups at the start of study (22.41 ± 7.67 vs. 22.90 ± 4.38, P = 0.76). At the end of study, the mean RLS score significantly decreased in the intervention group, while this score remained relatively un-changed in the control group (12.41 ± 5.49 vs. 23.23 ± 4.52, P < 0.0001). Lavender oil massage was effective to improve RLS in hemodialysis patients. It has no adverse effects, is practical and cost-effective. It is suggested to be used along with routine treatment of RLS in hemodialysis patients.

    Purpose Chronic hemodialysis patients experience accelerated atherosclerosis contributed to by dyslipidemia, inflammation, and an impaired antioxidant system. Vitamin E tocotrienols possess anti-inflammatory and antioxidant properties. However, the impact of dietary intervention with Vitamin E tocotrienols is unknown in this population. Patients and methods A randomized, double-blind, placebo-controlled, parallel trial was conducted in 81 patients undergoing chronic hemodialysis. Subjects were provided daily with capsules containing either vitamin E tocotrienol-rich fraction (TRF) (180 mg tocotrienols, 40 mg tocopherols) or placebo (0.48 mg tocotrienols, 0.88 mg tocopherols). Endpoints included measurements of inflammatory markers (C-reactive protein and interleukin 6), oxidative status (total antioxidant power and malondialdehyde), lipid profiles (plasma total cholesterol, triacylglycerols, and high-density lipoprotein cholesterol), as well as cholesteryl-ester transfer protein activity and apolipoprotein A1. Results TRF supplementation did not impact any nutritional, inflammatory, or oxidative status biomarkers over time when compared with the baseline within the group (one-way repeated measures analysis of variance) or when compared with the placebo group at a particular time point (independent t-test). However, the TRF supplemented group showed improvement in lipid profiles after 12 and 16 weeks of intervention when compared with placebo at the respective time points. Normalized plasma triacylglycerols (cf baseline) in the TRF group were reduced by 33 mg/dL (P=0.032) and 36 mg/dL (P=0.072) after 12 and 16 weeks of intervention but no significant improvement was seen in the placebo group. Similarly, normalized plasma high-density lipoprotein cholesterol was higher (P<0.05) in the TRF group as compared with placebo at both week 12 and week 16. The changes in the TRF group at week 12 and week 16 were associated with higher plasma apolipoprotein A1 concentration (P

    There have been major changes in the management of anemia in US hemodialysis patients in recent years. We sought to determine the influence of clinical trial results, safety regulations, and changes in reimbursement policy on practice. We examined indicators of anemia management among incident and prevalent hemodialysis patients from a medium-sized dialysis provider over three time periods: (1) 2004 to 2006 (2) 2007 to 2009, and (3) 2010. Trends across the three time periods were compared using generalized estimating equations. Prior to 2007, the median proportion of patients with monthly hemoglobin >12 g/dL for patients on dialysis 0 to 3, 4 to 6 and 7 to 18 months, respectively, was 42%, 55% and 46% declined to 41%, 54%, and 40% after 2007, and declined more sharply in 2010 to 34%, 41%, and 30%. Median weekly Epoeitin alpha doses over the same periods were 18,000, 12,400, and 9,100 units before 2007; remained relatively unchanged from 2007 to 2009; and decreased sharply in the patients 3-6 and 6-18 months on dialysis to 10,200 and 7,800 units, respectively in 2010. Iron doses, serum ferritin, and transferrin saturation levels increased over time with more pronounced increases in 2010. Modest changes in anemia management occurred between 2007 and 2009, followed by more dramatic changes in 2010. Studies are needed to examine the effects of declining erythropoietin use and hemoglobin levels and increasing intravenous iron use on quality of life, transplantation rates, infection rates and survival.

    Chronic kidney disease (CKD) is characterized by progressive irreversible deterioration of renal functions. Advanced stages of CKD are associated with oxidative stress due to the imbalance between oxidant production and antioxidant defense mechanisms. Survival of patients with end stage renal diseases is maintained on variable forms of renal replacement therapies (RRT) which include peritoneal dialysis, hemodialysis, and sometimes renal transplantation. In humans, Nuclear Respiratory Factor 1 (NRF-1) gene encodes for a transcription factor that, together with the transcriptional co-activator encoded by Peroxisome Proliferator activated Receptor Gamma coactivator 1 Alpha (PGC1-a) gene, stimulates the expression of a broad set of nuclear genes (as COX6C) which are involved in mitochondrial biogenesis and functions. As mitochondria are considered a major source of reactive oxidant species, the objective of the present study was to assess mitochondrial oxidative dysregulation occurring in chronic kidney disease patients undergoing hemodialysis employing NRF-1 and COX6C genes' expression as an indicator of mitochondrial oxidative metabolism. Forty-nine chronic kidney disease patients undergoing intermittent hemodialysis were included in the present study. A group of thirty-three age- and gender- matched healthy volunteers served as a control group. Assessment of expression of NRF-1 and COX6C genes was performed using quantitative real-time PCR technique. NRF-1 and COX6C expression showed a statistically significant difference between both studied groups being down-regulated in CKD patients. In addition, malondialdehyde (MDA) levels were higher in patients on hemodialysis indicating lipid peroxidation. A negative correlation was detected between MDA level and expression of both NRF-1 and COX6C genes. Chronic kidney disease patients undergoing hemodialysis might be subjected to potential mitochondrial oxidative dysregulation with subsequent possible vascular and tissue

    Hemodialysis is the first extrarenal treatment method that allowed supporting patients in terminal chronic failure in Senegal since 1997. 25 years later, we conducted this study to determine the type and the prevalence of different cardiovascular complications and identify the main cardiovascular risk factors. It is a retrospective study of 4 years. 38 patients treated at least 6 months in hemodialysis and cardiovascular explorations with a front chest x-ray, electrocardiogram and cardiac ultrasound. All patients who have not started hemodialysis, treated less than 6 months in hemodialysis, treaties in peritoneal dialysis or having raised cardiovascular explorations were excluded. For each selected patient, we collected data epidemiological, clinical, paraclinical and evolutionary aspects of cardiovascular complications. 38 patients were included in this study. The average age was 52 years ± 12.85 and the sex ratio H/F of 1.53. Initial nephropathy was dominated by the néphroangiosclérose followed by diabetic nephropathy. Clinically the signs of appeal are marked by the effort dyspnea palpitations, chest pain and physically by the HTA, anemia. Cardiovascular complications were dominated by hypertrophy (LVH) left ventricular, rhythm type of arrhythmia disorders valvular leakage (mitral and tricuspid) and cerebral vascular accident (stroke). The average impact of LVH according the HTA is 81%, by sex of 78.26% for men and 60% for women. At the end of the study, 27 patients were pursuing hemodialysis and 11 had died 6 (54%) of cardiovascular cause. Hemodialysis is a common purification technique in Senegal and its complications remain especially dominated by abuses cardiovascular.

    Visceral adipose tissue-derived serine proteinase inhibitor (vaspin) is an adipokine identified in genetically obese rats that correlates with insulin resistance and obesity in humans. Recently, we found that 7% of the Japanese population with the minor allele sequence (A) of rs77060950 exhibit higher levels of serum vaspin. We therefore evaluated the serum vaspin levels in Japanese chronic hemodialysis patients. Healthy Japanese control volunteers (control; n = 95, 49.9 ± 6.91 years) and Japanese patients undergoing hemodialysis therapy (HD; n = 138, 51.4 ± 10.5 years) were enrolled in this study, and serum samples were subjected to the human vaspin RIA system. The measurement of the serum vaspin levels demonstrated that a fraction of control subjects (n = 5) and HD patients (n = 11) exhibited much higher levels (> 10 ng/ml; Vaspin High group), while the rest of the population exhibited lower levels (< 3 ng/ml; Vaspin Low group). By comparing the patients in the Vaspin Low group, the serum vaspin levels were found to be significantly higher in the control subjects (0.87 ± 0.24 ng/ml) than in the HD patients (0.32 ± 0.15 ng/ml) (p < 0.0001). In the stepwise regression analyses, the serum creatinine and triglyceride levels were found to be independently and significantly associated with the vaspin concentrations in all subjects. The creatinine levels are negatively correlated with the serum vaspin levels and were significantly reduced in the Japanese HD patients in the Vaspin Low group.

    Adherence to a proper diet has a vast impact on the correct course of dialyses, wellbeing, and the results of some laboratory investigations in patients with declining renal failure. The nutritional status of dialysis patients is closely related to food and specific nutrients intake. The aim of study was assessment of dietary habits in dialysis patients. The study included 27 patients peritoneal dialysis (PD) and 92 hemodialysis (HD). In all of dialysis patients the following measurements were taken: body weight and height. The food intake was assessed by 24-hour dietary recall, (according to nutritional components). The portion size was estimated on the "Album of portions of products and dishes". The results were compared with dietary recommendations for dialysis patients and analyzed by computer software Dietetic 2 designed in the Institute of Food and Nutrition in Warsaw but computer program Statistica 7.0 was used for calculations. In all studied dialysis patients an irregular diet were observed. The diet was characterized by a low energetic value and low intake of proteins, carbohydrates, fiber and calcium, as well as by a too high fats. Among women's and man's in both groups were noted underweight: (W in PD patients--7%, M in DO patients--8%, W in HD patients--4%), overweight (W in PD patients--33%, M in DO patients--25%, W in HD patients--38%, M in HD patients--36%) and obesity (W in PD patients--26%, M in DO patients--33%, W in HD patients--22%, M in HD patients--21%). The study revealed that the daily food rations of peritoneal dialysis women were found to have a significantly higher the average intake dietary fiber (18.3 +/- 5.5 g/day) and higher potassium intake (2758.5 +/- 787.5 mg/day) as compared to the average intake dietary fiber (11.7 +/- 5.4 g/ day; p < 0.0001) and potassium intake (1612.9 +/- 822.9 mg/day; p < 0.0001) of hemodialysis women. The regular dietician advice is necessary for monitoring of patients nutrition.

    The autonomic maneuvers are simple methods to evaluate autonomic balance, but the association between autonomic maneuvers and heart rate variability (HRV) in hemodialysis patients remains unknown. This study aimed to evaluate the correlation between HRV and respiratory sinus arrhythmia (RSA) and Valsalva maneuver (VM) indexes in hemodialysis patients and to compare two methods for RSA indexes acquisitions. Forty-eight volunteers on hemodialysis (66.7 % men) were evaluated by VM, RSA, and 24 h Holter monitoring. At the VM, the Valsalva index (VI) was the variable considered. In the RSA, the ratio and difference between the RR intervals of inspiratory and expiratory phase (E:I and E-I, respectively) were considered by traditional form (average of respiratory cycles) and independent respiratory cycles (E:Iindep and E-Iindep). The HRV indexes evaluated were standard deviation of all normal RR intervals (SDNN), standard deviation of sequential 5-min RR interval means (SDANN), root mean square of the successive differences (rMSSD) and percentage of adjacent RR intervals with difference of duration greater than 50 ms (pNN50). The SDNN, SDANN showed significant correlation with all classic indexes of RSA (E:I: r = 0.62, 0.55, respectively, E-I: r = 0.64, 0.57, respectively), E:Iindep (r = 0.59, 0.54, respectively), E-Iindep (r = 0.47, 0.43, respectively) and VI (r = 0.42, 0.34, respectively). Significant correlation of rMSSD with E:I (r = 0.37), E-I (r = 0.41) and E:Iindep (r = 0.34) was also observed. There was no association of any variable with pNN50. Have been show high values for all variables of independent cycles method (p < 0.05). The autonomic maneuvers, especially RSA, are useful methods to evaluate cardiac autonomic function in hemodialysis patients. The acquisition of the RSA index by independent cycles should not be used in this population.

    Home hemodialysis (HHD) facilitates increased treatment frequency, which may improve patient outcomes. However, attrition due to technique failure limits the clinical effectiveness of the modality. Nx2me Connected Health is a telehealth platform that enables ongoing assessment of HHD patients using NxStage equipment, and that may reduce patient burden. We aimed to assess whether use of Nx2me was associated with risk of HHD attrition. We compared risks of all-cause attrition, dialysis cessation (i.e., death or transplant), and technique failure in Nx2me users and matched control patients, using a retrospective cohort study. We also compared the likelihood of HHD training graduation in patients who initiated use of Nx2me during training with the likelihood in matched control patients. Matching factors included date of HHD initiation, NxStage treatment duration at initiation of follow-up, and prescribed treatment frequency. We used stratified Fine-Gray and Cox regression to compare risks, with adjustment for demographic factors and vascular access modality, and stratification by matched cluster. We identified 606 Nx2me users; 49.5% initiated use of Nx2me in <3 months after initiation of HHD with NxStage equipment. Adjusted hazard ratios (AHRs) of all-cause attrition, dialysis cessation, and technique failure were 0.80 (95% confidence interval, 0.68-0.95), 1.10 (0.86-1.41), and 0.71 (0.57-0.87), respectively, for Nx2me users vs. matched controls. AHRs were similar in patients who initiated use of Nx2me in <3 months after initiation of HHD. The AHR of HHD training graduation was 1.61 (1.10-2.36) in patients who initiated use of Nx2me within 2 weeks of training initiation vs. matched controls. Use of Nx2me was associated with lower risk of all-cause attrition, lower risk of technique failure, and higher likelihood of HHD training graduation. Further studies are needed to identify the mechanisms by which use of a telehealth platform may improve clinical outcomes and

    Vascular calcification is common and may affect cardiac function in patients with end-stage renal disease (ESRD). However, little is known about the effect of residual renal function on vascular calcification and cardiac function in patients on hemodialysis. This study was conducted between January 2014 and January 2017. One hundred six patients with residual renal function on maintenance hemodialysis for 3 months were recruited. We used residual renal urea clearance (KRU) to measure residual renal function. First, abdominal aortic calcification score (AACS) and brachial-ankle pulse wave velocity (baPWV) were measured in patients on hemodialysis. Second, we performed echocardiography and investigated new cardiovascular events after study enrollment. The median KRU was 0.9 (0.3-2.5) mL/min/1.73m2. AACS (4.0 [1.0-10.0] vs. 3.0 [0.0-8.0], p = 0.05) and baPWV (1836.1 ± 250.4 vs. 1676.8 ± 311.0 cm/s, p = 0.01) were significantly higher in patients with a KRU < 0.9 mL/min/1.73m2 than a KRU ≥ 0.9 mL/min/1.73m2. Log-KRU significantly negatively correlated with log-AACS (ß = -0.29, p = 0.002) and baPWV (ß = -0.19, P = 0.05) after factor adjustment. The proportion of left ventricular diastolic dysfunction was significantly higher in patients with a KRU < 0.9 mL/min/1.73m2 than with a KRU ≥ 0.9 mL/min/1.73m2 (67.9% vs. 49.1%, p = 0.05). Patients with a KRU < 0.9 mL/min/1.73m2 showed a higher tendency of cumulative cardiovascular events compared to those with a KRU ≥ 0.9 ml/min/1.73m2 (P = 0.08). Residual renal function was significantly associated with vascular calcification and left ventricular diastolic dysfunction in patients on hemodialysis.

    Background: Restless leg syndrome (RLS) is a common problem in patients with chronic renal failure. It can reduce the quality of life and sleep disturbances. This disorder is usually treated pharmacologically. Recently, complementary medicine methods have been suggested because of chemical drugs adverse effects. There is not enough evidence about the effect of aromatherapy on RLS. Objectives: The aim of this study was to determine the effects of massage with lavender oil on RLS symptoms in hemodialysis patients. Patients and Methods: This randomized clinical trial study included 70 hemodialysis patients with RLS that were randomly assigned into two groups in 2014. The experimental group received effleurage massage using lavender oil and control group received routine care for three weeks. Data was collected with RLS questionnaire and analyzed using independent and paired t-test and Chi-square test. Results: The mean RLS scores were not significantly different in the two groups at the start of study (22.41 ± 7.67 vs. 22.90 ± 4.38, P = 0.76). At the end of study, the mean RLS score significantly decreased in the intervention group, while this score remained relatively un-changed in the control group (12.41 ± 5.49 vs. 23.23 ± 4.52, P < 0.0001). Conclusions: Lavender oil massage was effective to improve RLS in hemodialysis patients. It has no adverse effects, is practical and cost-effective. It is suggested to be used along with routine treatment of RLS in hemodialysis patients. PMID:26835466

    This study aimed to determine whether dental calculus formation is really higher among patients with chronic kidney disease undergoing hemodialysis than among controls. Furthermore, the study evaluated correlations between dental calculus formation and dental plaque, variables that are related to renal disease and/or saliva composition. The Renal Group was composed of 30 patients undergoing hemodialysis, whereas the Healthy Group had 30 clinically healthy patients. Stimulated whole saliva and parotid saliva were collected. Salivary flow rate and calcium and phosphate concentrations were determined. In the Renal Group the saliva collection was carried out before and after a hemodialysis session. Patients from both groups received intraoral exams, oral hygiene instructions, and dental scaling. Three months later, the dental calculus was measured by the Volpe-Manhold method to determine the rate of dental calculus formation. The Renal Group presented a higher rate of dental calculus formation (p < 0.01). Correlation was observed between rate of dental calculus formation and whole saliva flow rate in the Renal Group after a hemodialysis session (r = 0.44, p < 0.05). The presence of dental calculus was associated with phosphate concentration in whole saliva from the Renal Group (p < 0.05). In conclusion, patients undergoing hemodialysis presented accelerated dental calculus formation, probably due to salivary variables.

    To investigate changes in contingent negative variation (CNV) induced by uremia and to study the effects of hemodialysis. Fifteen right-handed healthy subjects and 12 patients with end-stage renal disease (ESRD) were studied. CNV was recorded from the Fz, Cz and Pz (using the International 10-20 System) referenced to linked ear lobes, using an S1 (click)-S2 (flashes)-key press paradigm. The amplitude of initial CNV (iCNV) was calculated as the average amplitude at 550-750 ms after S1. The amplitude of late CNV (lCNV) was the mean amplitude of the last 200 ms before S2. Testing was repeated for the patient group at pre- and post-hemodialysis observations. Neuropsychological measurements, a trail making test (TMT) and mini-mental state examination (MMSE), were conducted at each time. The mean amplitudes of iCNV and lCNV at the vertex (Cz) were both significantly lower in the patient group than in the control group (P<0.05). TMT were also significantly different between patient and control groups (P<0.05)), however MMSE showed no significant difference. There were no significant correlations between the values of neuropsychological tests and the parameters of CNV. Both iCNV and lCNV were not significantly different between the pre- and post-dialysis tests. CNV negativity in patients with ESRD reflects diffuse nonlocalizing neurological symptoms of uremia rather than a selective involvement of the frontal lobes. It is likely to reflect dysfunction in the frontal-subcortical circuit. In addition, hemodialysis seemed to have no significant effect on executive brain function in these patients with ESRD.

    Coronary artery disease contributes significantly to mortality in end-stage renal disease (ESRD) patients. Single-photon emission computed tomography (SPECT) using an iodinated fatty acid analogue, iodine-123-methyl iodophenylpentadecanoic acid (123I-BMIPP), can assess fatty acid metabolism in the myocardium. We investigated the ability of 123I-BMIPP SPECT to detect coronary artery disease in hemodialysis patients compared with 201thallium chloride (201Tl) SPECT. We prospectively studied 130 ESRD patients undergoing hemodialysis for a mean of 88.6 months (male/female, 77/53; mean age, 63.8 years). Dual SPECT using 123I-BMIPP and 201Tl was performed, followed by coronary angiography. SPECT findings were graded in 17 segments on a five-point scale (0, normal uptake; 4, none) and assessed as a summed score. By coronary angiography, 71.5% of patients (93/130) had significant coronary stenosis (> or =75%), and five patients showed coronary spasm without coronary stenosis. When a BMIPP summed score of 6 or more was defined as abnormal, sensitivity, specificity, and accuracy for detecting coronary artery disease by BMIPP SPECT were 98.0%, 65.6%, and 90.0%, respectively; in contrast, these parameters for detecting coronary artery disease by Tl SPECT were 84.7%, 46.9%, and 75.0%, respectively, when a Tl summed score of 1 or more was defined as abnormal. In receiver operating characteristic analysis, the area under the curve was 0.895 in BMIPP and 0.727 in Tl SPECT, respectively. Resting BMIPP SPECT is superior to Tl SPECT for detecting coronary lesions, and provides safe screening for coronary artery disease among maintenance hemodialysis patients.

    In hemodialysis patients, sedentarism is a potentially modifiable mortality risk factor. We explored whether healthcare staff's attitude towards exercise interacts with patient-perceived barriers in modifying the level of physical activity in this population. In this prospective, cross-sectional, multicenter study we recruited 608 adult patients and 330 members of the healthcare staff in 16 hemodialysis units in Italy. We assessed patient-perceived barriers to, and healthcare staff's attitude towards, exercise by specific questionnaires. We fitted multilevel linear models to analyze the relationships of either barriers or staff's attitude, and their interaction, with a measure of patient self-reported physical activity (the Human Activity Profile-Adjusted Activity Score [HAP-AAS]), adjusting for multiple confounders. We also employed latent class analysis to dichotomize patients into those endorsing or not endorsing barriers. Most barriers were negatively associated with the HAP-AAS (adjusted change attributable to a given barrier ranging between -5.1 ["Feeling too old", 95% Confidence Interval: -9.4 to -0.8] and -15.6 ["Ulcers on legs and feet", 95%CI: -24.8 to -6.5]. We found a significant interaction between staff's attitude and barriers (adjusted P values ranging between 0.03 ["I do not believe that it is physician's or nurse's role providing advice on exercise to patients on dialysis"] and 0.001 ["I do not often ask patients about exercise"]). A beneficial effect of a proactive staff's attitude was evident only in patients not endorsing barriers. Barriers and non-proactive staff's attitude reduce physical activity in hemodialysis patients. Patients not endorsing barriers benefit the most from a proactive staff's attitude.

    Previous research has demonstrated improved outcomes for patients on dialysis who have better quality of life and self-efficacy, but has focused almost exclusively on those receiving hemodialysis. The goal of this study was to describe the quality of life and self-efficacy of patients receiving incenter hemodialysis versus those receiving a home dialysis modality (hemodialysis or peritoneal dialysis). The study utilized a correlational cross-sectional design and quota sampling methods. Participants were recruited from outpatient dialysis facilities and included 77 community dwelling adult patients who had been on dialysis for at least six months. Quality of life was measured using the Kidney Disease Quality of Life instrument, and self-efficacy was measured using the Strategies Used by People to Promote Health instrument. Findings suggest equal outcomes between treatment groups, with no contraindication to the use of home therapies.

    Secondary hyperparathyroidism (SHPT) is a frequent complication in chronic kidney disease, especially in hemodialysis (HD) patients. Treatments for SHPT include calcitriol analogues (CA), phosphate binders, cinacalcet (CC), and surgical parathyroidectomy (PTX). This study aimed to assess the incidence and prevalence of SHPT in a single center during the period when native vitamin D (N-VitD) supplementation and CC treatment became available. All incident and prevalent HD patients were prospectively recorded and compared using 3 periods from 2004 to 2005 (period 1), 2006 to 2007 (period 2), and 2008 to 2009 (period 3). SHPT was diagnosed with serum parathyroid hormone (PTH) levels >300 pg/mL or the need for CA, CC, or PTX. Between periods 1 and 3, in incident patients (n=120 and 101), N-VitD prescription increased from 11% to 68% (P<0.0001), CA prescription remained stable (40%), and patients with PTH>300 pg/mL decreased from 40% to 12% (P<0.0001). In prevalent HD patients (n=235), N-VitD treatment increased from 55% to 91% (P<0.0001), whereas treatment with CA decreased from 67% to 17% (P<0.0001). Patients with serum PTH>300 pg/mL decreased from 38% to 13% (P<0.001), whereas patients with PTH<150 pg/mL remained stable (<30%). New CC prescriptions decreased from 45 to 3 (P<0.0001). Since 2004, SHPT has decreased drastically in incident and prevalent HD patients. The preventive role of N-VitD supplementation appears to be obvious and represents one more argument for its general recommendation in CKD patients. © 2010 The Authors.

    The Iodine-131 (I-131) is a radioisotope used as a standard treatment for radioablation of thyroid remnants. Among thyroid cancer patients, the ones undergoing hemodialysis represent a specific group. The dose of I-131 is given orally to these patients, part of it is absorbed by the thyroid remnants and the rest of it, largely not incorporated, is excreted primarily by renal excretion. The use of a high dose of radioactivity in the process, and the inability of excretion, represents a high risk of exposure to the patient, medical staff and hemodialysis equipment. This work describes the procedure applied on the radioablation therapy for thyroid cancer while receiving hemodialysis, minimizing the risks for the patient and the staff involved. This clinical procedure will establish the dosimetric measures, a plan on radiation protection and a treatment protocol for this specific type of patients.

    Phosphate control is a crucial treatment goal in end-stage renal disease, but poor patient adherence to phosphate binder therapy remains a challenge. This study aimed to estimate the extent of phosphate binder adherence in hemodialysis patients and to identify potential determinants. Phosphate binder adherence was measured blindly in 135 hemodialysis patients for 2 months using the medication event monitoring system. Patient data, gathered at inclusion through medical records, ad hoc questionnaires and the short form (SF)-36 health survey, included: (1) demographics, (2) perceived side-effects, belief in benefit, self-reported adherence to the therapy, (3) knowledge about phosphate binder therapy, (4) social support, and (5) quality of life (SF-36). Phosphatemia data was collected from charts. 'Being adherent' was defined as missing <1 total daily dose/week and 'being totally adherent' as missing <1 total daily dose/week, every week. Mean age of patients was 67 years and 64 % of the sample was male. Over the 2 months, 78 % of the prescribed doses were taken. Every week, about half of patients were adherent. Over the entire 8-week period, 22 % of patients were totally adherent. Mean phosphatemia levels were 0.55 mg/dl lower in adherent than nonadherent patients (4.76 vs. 5.31 mg/dl). Determinants for being totally adherent were living with a partner, higher social support (both were interrelated) and higher physical quality of life. Experiencing intake-related inconvenience negatively affected adherence. The social support and quality of life physical score explained 26 % of the variance in adherence. Phosphate binder nonadherence remains a major problem. Interventions should aim, at least, to improve social support. With few associated factors found and yet low adherence, an individualized approach seems indicated.

    Background and objectives Patients on hemodialysis have a high rate of hip fractures. In this study, we performed a contemporary analysis of mineral and bone parameters and their relationship to hip and femur fracture risk. Design, setting, participants, & measurements Patients on hemodialysis treated between 2000 and 2013 in Fresenius Medical Care North America facilities were included. Predictors were on the basis of data as of December 31 of each baseline year and time-averaged values of selected laboratory parameters and medication doses throughout the year. Four period cohorts were constructed from baseline years: 2000, 2003, 2006, and 2009. Follow-up for each cohort was ≤3 years. Results The incidence of hip and femur fractures remained generally unchanged (P=0.40), except among patients who were white and >65 years of age, in whom the rate decreased significantly over the 14-year period (P<0.01). Results from combined multivariable models indicated that the lowest quartiles of time–averaged intact parathyroid hormone were independently associated with higher hip fracture risk (intact parathyroid hormone =181–272 pg/ml: hazard ratio, 1.20; 95% confidence interval [95% CI], 1.03 to 1.41 and intact parathyroid hormone <181 pg/ml: hazard ratio, 1.20; 95% CI, 1.01 to 1.44; referent third quartile, 273 to <433 pg/ml). The lowest quartile of time–averaged serum calcium was also associated with higher risk (calcium <8.7 mg/dl; hazard ratio, 1.17; 95% CI, 1.00 to 1.37) compared with the referent third quartile of 9.1 to <9.5 mg/dl. Conclusions We found an association between lower levels of intact parathyroid hormone and serum calcium and greater risk for hip and femur fractures among patients on hemodialysis. These findings support additional research toward elucidating long-term safety of treatment approaches for hyperparathyroidism in patients with ESRD. PMID:27026521

    The aim of the study was to analyse the epidemiology and prognosis of candidaemia in elderly patients. We performed a comparison of clinical presentation of candidaemia according to age and a study of hazard factors within a prospective programme performed in 29 hospitals. One hundred and seventy-six episodes occurred in elderly patients (>75 years), 227 episodes in middle-aged patients (61-75 years) and 232 episodes in younger patients (16-60 years). Central venous catheter, parenteral nutrition, neutropenia, immunosuppressive therapy and candidaemia caused by Candida parapsilosis were less frequent in elderly patients. These patients received inadequate antifungal therapy (57.3%) more frequently than middle-aged and younger patients (40.5% P < .001). Mortality during the first week (20%) and 30 days (42%) was higher in elderly patients. The variables independently associated with mortality in elderly patients during the first 7 days were acute renal failure (OR: 2.64), Pitt score (OR: 1.57) and appropriate antifungal therapy (OR: 0.132). Primary candidaemia (OR: 2.93), acute renal failure (OR: 3.68), Pitt score (OR: 1.38), appropriate antifungal therapy (OR: 0.3) and early removal of the central catheter (OR: 0.47) were independently associated with 30-day mortality.In conclussion, inadequate antifungal treatment is frequently prescribed to elderly patients with candidaemia and is related with early and late mortality. © 2017 Blackwell Verlag GmbH.

    We aimed to determine the prevalence of MRSA colonization and examine the molecular characteristics of colonizing isolates in patients receiving hemodialysis and HIV-infected in a Colombian hospital. Patients on hemodialysis and HIV-infected were prospectively followed between July 2011 and June 2012 in Bogota, Colombia. Nasal and axillary swabs were obtained and cultured. Colonizing S. aureus isolates were identified by standard and molecular techniques. Molecular typing was performed by using pulse-field gel electrophoresis and evaluating the presence of lukF-PV/lukS-PV by PCR. A total of 29% (n = 82) of HIV-infected and 45.5% (n = 15) of patients on hemodialysis exhibited S. aureus colonization. MSSA/MRSA colonization was observed in 28% and 3.6% of the HIV patients, respectively and in 42.4% and 13.3% of the hemodialysis patients, respectively. Staphylococcal cassette chromosome mec typing showed that four MRSA isolates harbored the type IV cassette, and one type I. In the hemodialysis group, two MRSA isolates were classified as belonging to the USA300-LV genetic lineage. Conversely, in the HIV infected group, no colonizing isolates belonging to the USA300-Latin American Variant (UDA300-LV) lineage were identified. Colonizing isolates recovered from the HIV-infected group belonged to the prevalent hospital-associated clones circulating in Latin America (Chilean [n = 1] and Pediatric [n = 2]). The prevalence of MRSA colonization in the study groups was 3.6% (HIV) and 13.3% (hemodialysis). Surveillance programs should be implemented in this group of patients in order to understand the dynamics of colonization and infection in high-risk patients. PMID:26474075

    Although renal replacement therapy can lead to improved health, it also can cause emotional disturbances in patients. It is believed that the success of renal replacement therapy hinges not only on medical parameters, but also on psychosocial factors, which is why modern medicine provides an ever-increasing role in the improvement of patients' quality of life. The purpose of this study was to compare the level of life satisfaction, purpose in life, and basic hope in patients who had received renal replacement due to chronic kidney disease. We also tested whether the specific type of renal replacement therapy and kidney function parameters were influential factors on the above variables. Sixty-one adult patients treated via renal replacement for chronic kidney disease took part in the study. Patients were divided into two groups: 31 hemodialysis patients (15 women and 16 men, ages 23-77 years, mean 51.19 years, SD 14.53 years) and 30 patients who had undergone kidney transplantation (14 women and 16 men, ages 22-69 years, mean 48.40 years, SD 12.64 years). The following research tools were used for analysis: Satisfaction With Life Scale (SWLS), Purpose in Life Test (PIL), and Basic Hope Inventory (BHI-12). There were no statistical differences in the level of satisfaction with life between hemodialysis patients and postkidney transplant patients. The results for the SWLS obtained from both groups fell within the normal range. The average SWLS for hemodialysis patients remained 20.61, SD = 5.79; for postkidney transplant patients, it was 22.57, SD = 5.16. The PIL level in the group of hemodialysis patients (101.5, SD = 15.64) was significantly lower than in the group of postkidney transplant patients (109.7, SD = 15.54). The average BHI-12 level was similar in both groups. The average BHI-12 result for hemodialysis patients was 29.00 (SD = 5.06), and for postkidney transplant patients 29.93 (SD = 3.55).

    Protein-calorie malnutrition as well as systemic inflammation and metabolic disorders are common among patients with chronic renal failure undergoing renal replacement therapy (hemodialysis), which contributes to their morbidity and mortality. This work has followed 90 patients of both sexes with chronic kidney disease who were treated with hemodialysis periodically in our unit for four years. All patients were performed quarterly measurements of plasma albúmina (A1b), total cholesterol (TC), total protein (TP) and monthly transferrin (Tr), Anthropometric measurements of height and weight were taken on all patients by using a balance/stadiometer (Perperson 113481); weight was measured in kilograms and height in centimetres. BMI was calculated with this formula: weight/height2 and classified according to the WHO criteria: BMI < 18.50: Underweight; from 18.50 to 24.99: Normal range; from 25.00 to 29.99: Overweight; and BMI > or =30.00: Obese. The aim of this work was evaluate the nutritional status of these patients through the assessment of biochemical parameters and anthropometric parameters and determine if these patients suffer alterations suggesting nutritional deterioration directly related to the time on dialysis. During the 4 years all patients showed a significant decline of biochemical parameters, on the other hand the BMI did not significant changes in relation to malnutrition. Malnutrition in patients on dialysis is therefore evident, the BMI does not correspond with the biochemical parameters observed, so nutritional deterioration of these patients is mainly manifested by biochemical parameters studied.

    The arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis patients. Unfortunately, 20-40% of all constructed AVFs fail to mature (FTM), and are therefore not usable for hemodialysis. AVF maturation importantly depends on postoperative blood volume flow. Predicting patient-specific immediate postoperative flow could therefore support surgical planning. A computational model predicting blood volume flow is available, but the effect of blood flow predictions on the clinical endpoint of maturation (at least 500 mL/min blood volume flow, diameter of the venous cannulation segment ≥4 mm) remains undetermined. A multicenter randomized clinical trial will be conducted in which 372 patients will be randomized (1:1 allocation ratio) between conventional healthcare and computational model-aided decision making. All patients are extensively examined using duplex ultrasonography (DUS) during preoperative assessment (12 venous and 11 arterial diameter measurements; 3 arterial volume flow measurements). The computational model will predict patient-specific immediate postoperative blood volume flows based on this DUS examination. Using these predictions, the preferred AVF configuration is recommended for the individual patient (radiocephalic, brachiocephalic, or brachiobasilic). The primary endpoint is FTM rate at six weeks in both groups, secondary endpoints include AVF functionality and patency rates at 6 and 12 months postoperatively.

    Mortality and morbidity rate, especially from cardiovascular disease in hemodialysis patients in Indonesia is still quite high. One of indicator to assess the predictive value of mortality is the phase angle (PhA) of bioimpedance analysis (BIA) scan examination. Determining the comparison of BMI and laboratory data as cardiovascular risk factors in hemodialysis patients based on PhA.A cross-sectional analytical study was done on 155 outpatientsin RasyidaRenal Hospital, Medan in 2016. Patients were two groups, namely PhA<4 group and ≥ 4 group. The comparison of BMI and laboratory data based on PhA were by analyzingthe independent T-test. A P-value <0.05 was considered statistically significant. Most of thepatients are male (56.7%), obese (39.4%), with age 40-59 years (56.1%). Based on PhA, 56.7% patients have PhA ≥4. There are differences in the profile of age (p: 0.01), BMI (p: 0.028) and hemoglobin (p: 0.00) between two groups, but not in the profile of albumin (p: 0.071), total cholesterol (p: 0.65), HDL (p: 0.06), LDL (p: 0.07), triglyceride (p: 0.87), calcium (p: 0.59) and phosphorus (p: 0.17).Based onPhA, the cardiovascular risk factors of hemodialysis patients were determined by age, BMI, and hemoglobin.

    Endothelial dysfunction is an important risk factor for cardiovascular diseases to occur in end-stage renal disease patients. Febuxostat, being a novel xanthine oxidase inhibitor, is apparently having a beneficial role in improving the endothelial dysfunction; however, data among hemodialysis patients are still limited. A prospective, placebo-controlled, block-randomized, double-blinded study was carried out to evaluate the effect of oral febuxostat on the endothelial dysfunction in hemodialysis patients. Fifty-seven eligible hemodialysis patients were randomly assigned to either the drug group (40 mg thrice weekly) or the placebo group. Serum Asymmetric dimethylarginine (ADMA), Serum uric acid (UA), and serum high sensitivity C-reactive protein (hsCRP) were measured at baseline and at the end of a 2-month study. Serum alanine aminotransferase (ALT), serum aspartate aminotransferase (AST), and the occurrence of pancytopenia were tested as safety parameters at baseline and at the end of study. Serum UA significantly decreased from 7.5 ± 0.8 to 5.1 ± 1.2 mg/dL in the febuxostat group, while it did not change significantly in the placebo group. Treatment with febuxostat resulted in a significant decrease in the serum ADMA level from 1.027 ± 0.116 to 0.944 ± 0.104 µmol/L and the serum hsCRP level from 12.5 ± 1.65 to 12.1 ± 1.70 mg/L. Testing of serum ALT, serum AST, and pancytopenia revealed no significant difference in both groups. Febuxostat appears to improve hyperuricemia and endothelial dysfunction and ameliorate inflammation in hemodialysis patients with no safety concerns. © 2017 S. Karger AG, Basel.

    In this cross-sectional study, we hypothesized that hemodialysis patients consuming greater processed meat is associated with hypertension risk, which can be partly explained by the high sodium content in processed meat. From September 2013 to May 2014, one hundred and four patients requiring chronic hemodialysis treatment were recruited from hemodialysis centers. Data on systolic blood pressure and diastolic blood pressure before receiving dialysis, and 3-day dietary records of the recruited patients were collected. HD patients with systolic and diastolic blood pressures greater than140 mmHg and higher than 90 mmHg, respectively, were considered hypertension risk. Protein foods were divided into 4 categories: red meat, white meat, soybeans, and processed meat (e.g., sausage and ham). In a model adjusted for energy intake and hypertension history, additional servings of processed meats was positively associated to systolic blood pressure >140 mmHg (odds ratio [95% confidence interval]: 2.1 [1.0–4.3]), and diastolic blood pressure > 90 mmHg (odds ratio: 2.5 [1.2–5.5]). After adjustment for dietary sodium contents or body mass index (BMI), most associations were substantially attenuated and were no longer significant. In systolic blood pressure greater than140 mmHg, one serving per day of red meats (β = -1.22, P < .05) and white meats (β = -0. 75, P = .05) was associated with a reduced risk compared with one serving per day of processed meats. Similarly, compared with one serving per day of processed meat, a reduced risk of diastolic blood pressure higher than 90 mmHg was associated with one serving per day of red meat (β = -1. 59, P < .05), white meat (β = -0. 62, P < .05). Thus, in these hemodialysis patients, intake of processed meat is significantly positively associated with higher blood pressure risk, and both sodium contents in processed meat and BMI significantly contributes to this association.

    The administration of hemodialysis (HD) treatment leads to the continuous collection of a vast quantity of medical data. Many variables related to the patient health status, to the treatment, and to dialyzer settings can be recorded and stored at each treatment session. In this study a dataset of 42 variables and 1526 patients extracted from the Fresenius Medical Care database EuCliD was used to develop and apply a random forest predictive model for the prediction of cardiovascular events in the first year of HD treatment. A ridge-lasso logistic regression algorithm was then applied to the subset of variables mostly involved in the prediction model to get insights in the mechanisms underlying the incidence of cardiovascular complications in this high risk population of patients.

    Serum hyaluronan levels are increased in dialysis patients. We evaluated several factors that influence serum hyaluronan levels in 184 patients on chronic hemodialysis (duration 2.3 +/- 2.3 [SD] years). The levels were higher than normal in the whole group and in a subgroup of 133 patients without chronic infection, liver disease, or rheumatoid arthritis (215 +/- 19 and 205 +/- 22 microg/L, respectively). There was a tendency for the levels to be higher in a subgroup of patients with hepatitis c virus (HCV) infection. There was no correlation between hyaluronan levels, alanine aminotransferase (ALT), and duration or dose of dialysis. A weak but highly significant negative correlation between serum albumin levels and serum hyaluronan and ferritin levels was seen. The data suggest that chronic inflammation may explain, at least in part, the increased hyaluronan levels found in chronic dialysis patients.

    The goal of this study was to assess the relationship between emotion- and task-oriented coping (EOC/TOC) with stress and employment in patients undergoing maintenance hemodialysis. Individuals aged 18 to 64 yr who had uremia and had been undergoing hemodialysis regularly for at least three months were evaluated according to sociodemographic and clinical factors. Work status was defined using the most recent International Labour Organization definitions. Patients were requested to complete the following questionnaires: the Japanese version of the Coping Inventory for Stressful Situations, the Short Form-36 Health Survey, an item on itchiness, the Self-Efficacy on Health-Related Behavior Scale, the Japanese version of the Health Locus of Control Scale, the Social Support Scale, and the Japanese version of the Hospital Anxiety and Depression Scale. A total of 317 individuals participated in this study. Among men, age, physical functioning, EOC, and depression differed significantly (p<0.05) depending on employment. Among women, marital status, household composition, EOC, depression, and anxiety differed significantly (p<0.05) depending on employment. TOC was not significantly associated with employment in either sex. Multiple logistic regression analyses, including possible confounders, indicated that when EOC increased by 10 points, the associated adjusted odds ratio of an unemployed or economically inactive status changed by 1.48 (95% confidence interval, 1.04-2.11; p=0.030) in men and by 1.88 (95% confidence interval, 1.02-3.46; p=0.042) in women. These results suggest that EOC is associated with employment in patients receiving maintenance hemodialysis.

    Malnutrition is an important predictive factor for morbidity and mortality in patients on maintenance dialysis. The evidence on the magnitude of the problem in sub-Saharan Africa is scanty. We assessed the nutritional status of patients on maintenance hemodialysis in the renal unit of the Douala General Hospital (Cameroon). Patients on maintenance hemodialysis for ≥3 months were enrolled between March and June 2012. Nutritional status was assessed via dietary recalls, anthropometric, and biochemical measurements including body mass index (BMI), triceps skinfold thickness, mid-arm circumference, mid-arm muscle circumference (MAMC), serum albumin, C-reactive protein (CRP) and hemoglobin, calcium, phosphorus, and vitamin D. A total of 113 patients (75 men) were included. They were aged 49.4 years, and had been on dialysis for a median of 25 months. The mean BMI, MAMC and serum albumin was 22.4 kg/m(2), 23.7 cm and 42.4 g/l respectively. We observed that 28.3 % of patients were underweight (BMI ≤20 kg/m(2)), 23.9 % had muscle wasting (MAMC < adequacy to 50th percentile), and 31.6 % had low serum albumin (≤40 g/dl), while 21 % of patients had a combination of the three abnormalities. Prevalence rates for other indicators of under-nutrition were 26.3 % (low plasma cholesterol), 28 % (positive CRP) and 82.7 % (anemia). Female gender, younger age, less meals/day and frequent vegetable intake were associated with malnutrition risk. Patients on maintenance hemodialysis in this setting have rates of malnutrition similar to those reported elsewhere. However, the high prevalence of malnutrition among women and young patients deserves further consideration.

    Background: Acute cholecystitis is the major complication of biliary lithiasis, for which laparoscopic treatment has been established as the standard therapy. With longer life expectancy, acute cholecystitis has often been seen in elderly patients (>65 years old) and is often accompanied by comorbity and severe complications. We sought to compare the outcome of laparoscopic treatment for acute cholecystitis with special focus on comparison between elderly and nonelderly patients. Method: This study was a prospective analysis of 190 patients who underwent laparoscopic cholecystectomy due to acute cholecystitis or chronic acute cholecystitis, comparing elderly and nonelderly patients. Results: Of 190 patients, 39 (21%) were elderly (>65 years old) and 151 (79%) were not elderly (≤65 years), with conversion rates of 10.3% and 6.6% (P=0.49), respectively. The incidence of postoperative complications in elderly and nonelderly patients were the following, respectively: atelectasis 5.1% and 2.0% (P=0.27); respiratory infection 5.1% and 2.7% (P=0.6); bile leakage 5.1% and 2.0% (P=0.27), and intraabdominal abscess 1 case (0.7%) and no incidence (P=1). Conclusion: According to our data, laparoscopic cholecystectomy is a safe and efficient procedure for the treatment of acute cholecystitis in patients older than 65 years of age. PMID:17575761

    Depression is highly prevalent in hemodialysis patients and results in poor patient outcomes. Although psychological interventions are being developed and used for these patients, there is uncertainty regarding the effectiveness of these interventions. The purpose of this meta-analysis is to evaluate the effects of psychological interventions on depression treatment in hemodialysis patients. All randomized controlled trials (RCTs) relevant to the depression treatment of hemodialysis patients through psychological interventions were retrieved from the following databases: Embase, Pubmed, PsycINFO, the Cochrane Database of Systematic Reviews, and the Cochrane Central Register of Controlled Trials. The reference lists of identified RCTs were also screened. The Cochrane risk of bias tool was used to evaluate the quality of the studies, RevMan (5.3) was used to analyze the data, and the evidence quality of the combined results was evaluated using GRADE (3.6.1). Eight RCTs were included. The combined results showed that psychological interventions significantly reduced the scores of the Beck Depression Inventory (P<0.001) and interdialysis weight gain (P<0.001). However, due to the high heterogeneity, effect size combinations of sleep quality and quality of life were not performed. Psychological interventions may reduce the degree of depression and improve fluid intake restriction adherence. More rigorously designed research is needed.

  8. Hypertension and hemodialysis: pathophysiology and outcomes in adult and pediatric populations.

    Hypertension is prevalent in adult and pediatric end-stage renal disease patients on hemodialysis. Volume overload is a primary factor contributing to hypertension, and attaining true dry weight remains a priority for nephrologists. Other contributing factors to hypertension include activation of the sympathetic and renin-angiotensin-aldosterone systems, endothelial cell dysfunction, arterial stiffness, exposure to hypertensinogenic drugs, and electrolyte imbalances during hemodialysis. Epidemiologic studies in adults show that uncontrolled hypertension results in cardiovascular morbidity, but reveal increased mortality risk at low blood pressure, so that it remains unclear what the target blood pressure should be. Despite the lack of a definitive BP target, gradual dry weight reduction should be the first intervention for BP control. Renin-angiotensin-aldosterone system inhibitors have been shown to improve cardiovascular morbidity and mortality and are recommended as the initial pharmacologic therapy for hypertensive hemodialysis patients. Short-daily or nocturnal hemodialysis are also good therapeutic options for these patients. It is already established that hypertension in pediatric hemodialysis patients is associated with adverse cardiovascular outcomes, and there is emerging evidence that the mechanisms causing hypertension are similar to adults. Hypertension in adult and pediatric hemodialysis patients warrants aggressive management, although clinical trial evidence of a target BP that improves mortality does not currently exist.

    When a person's kidneys fail, hemodialysis (HD) is the most common treatment modality. With a growing number of patients requiring this life-sustaining treatment, and with evidence illustrating the significant physical dysfunction of this population, encouraging exercise is essential. The use of intradialytic exercise, as a novel and efficient use of time during HD, is well established in Australia and some European nations; however, it is slower to start in North America. While a large number of small studies have demonstrated numerous benefits and safe delivery of intradialytic exercise training for patients with end-stage kidney disease, intradialytic exercise is rarely delivered as standard of care. It is of utmost importance for health care staff to overcome barriers and bring theory into practice. Included in this report are current recommendations from governing bodies, expert opinion, as well as established policies and procedures from a successful intradialytic exercise program in Canada.

    Peginesatide, a synthetic peptide-based erythropoiesis-stimulating agent (ESA), is a potential therapy for anemia in patients with advanced chronic kidney disease. We conducted two randomized, controlled, open-label studies (EMERALD 1 and EMERALD 2) involving patients undergoing hemodialysis. Cardiovascular safety was evaluated by analysis of an adjudicated composite safety end point--death from any cause, stroke, myocardial infarction, or serious adverse events of congestive heart failure, unstable angina, or arrhythmia--with the use of pooled data from the two EMERALD studies and two studies involving patients not undergoing dialysis. In the EMERALD studies, 1608 patients received peginesatide once monthly or continued to receive epoetin one to three times a week, with the doses adjusted as necessary to maintain a hemoglobin level between 10.0 and 12.0 g per deciliter for 52 weeks or more. The primary efficacy end point was the mean change from the baseline hemoglobin level to the mean level during the evaluation period; noninferiority was established if the lower limit of the two-sided 95% confidence interval was -1.0 g per deciliter or higher in the comparison of peginesatide with epoetin. The aim of evaluating the composite safety end point in the pooled cohort was to exclude a hazard ratio with peginesatide relative to the comparator ESA of more than 1.3. In an analysis involving 693 patients from EMERALD 1 and 725 from EMERALD 2, peginesatide was noninferior to epoetin in maintaining hemoglobin levels (mean between-group difference, -0.15 g per deciliter; 95% confidence interval [CI], -0.30 to -0.01 in EMERALD 1; and 0.10 g per deciliter; 95% CI, -0.05 to 0.26 in EMERALD 2). The hazard ratio for the composite safety end point was 1.06 (95% CI, 0.89 to 1.26) with peginesatide relative to the comparator ESA in the four pooled studies (2591 patients) and 0.95 (95% CI, 0.77 to 1.17) in the EMERALD studies. The proportions of patients with adverse and serious

    The aim of the study was to determine the prevalence and quality of control of disorders of calcium and phosphorus metabolism among patients on hemodialysis in Lithuania during the period of 2004-2005 and to assess rarely used methods of treatment such as parathyroidectomy and administration of calcimimetics. All Lithuanian hemodialysis centers were visited, and data on disorders of calcium-phosphorus metabolism were collected in December 2004 and 2005. The quality of control was evaluated according to Kidney Disease Outcome Quality Initiative recommendations. According to Kidney Disease Outcome Quality Initiative guidelines, normal parathyroid hormone levels were found in 20.4% of hemodialysis patients in 2004 and 18.8% of hemodialysis patients in 2005; normal levels of phosphate were in 41.9% and 39.4%, respectively; normal levels of calcium were observed in 44.7% of patients in 2004 and in 42.3% of patients in 2005. In 2005 as compared to 2004, there were statistically significantly more patients with low parathyroid hormone level (39.9% and 45.8%, respectively, P<0.05). Only in 5.6% of patients in 2004 and 3.9% of patients in 2005, all four parameters of calcium-phosphate metabolism (calcium, phosphate, and of parathyroid hormone levels and calcium-phosphate product) were within the normal range. No parameters in the normal range were found in 17-20% of patients. The use of alfacalcidol significantly increased: 316 (30.8%) patients in 2004 and 388 (35.7%) patients in 2005 were treated with alfacalcidol (P<0.05). Alfacalcidol was prescribed for 16.5% of patients in 2004 and for 17% of patients in 2005, in whom parathyroid hormone level was below the normal range in the presence of hypercalcemia and hyperphosphatemia. The use of calcimimetics was considered rational in 142 (13.8%) patients in 2004 and 119 (10.9%) patients in 2005. According to the data of our study, parathyroidectomy was indicated in 19 (1.85%) patients in 2004 and 17 (1.56%) patients in 2005

    The development of robust non-invasive laboratory screening methods for early diagnosis on the out-patient basis seems quite relevant for practical medicine. It is known, that platelet is an original biosensor, a detector of early changes in hemostasis condition. The aim of this study was to assess a potential of the quantitative phase imaging (QPI) technique for real time evaluation the influence of low-molecular weight and unfractionated heparin on platelets in patients with the end-stage of chronic renal failure, who were treated with program hemodialysis (PHD). The main group consisted of 21 patients who were administered a low-molecular weight heparin for hypocoagulation during the procedure of hemodialysis. The control group (15 patients) received unfractionated heparin. Morphodensitometric state of living platelets we evaluated by QPI using computer phase-interference microscope MIM (Moscow, Russia). We analyzed the optical-geometrical parameters and the morphological features of living platelets which reflected the degree of their activation at the beginning of PHD (before administration of heparin), in 15 minutes after it and at the end of the procedure. The results allow us to conclude that the use of low-molecular weight heparin provides better ratio of efficacy/safety and causes a reduction of the platelet activation during the hemodialysis procedure. Practical implementation of QPI for clinical monitoring of platelets makes it possible to obtain important information on hemostasis cell. It opens new opportunities to assess the efficacy of treatment, as well as for early diagnosis of complications for disease.

  13. Phosphate removal and hemodialysis conditions.

    PubMed

    2001-02-01

    Hyperphosphatemia is frequently found in hemodialysis patients, and the association with an increased risk of mortality has been demonstrated. Other authors have linked hyperphosphatemia to increased cardiovascular mortality. The normalization of phosphate plasma levels is therefore an important goal in the treatment of end-stage renal disease patients. Absorption of phosphate from the food exceeds the elimination through a hemodialysis treatment, and this leads to a chronic phosphate load for the majority of hemodialysis patients. This imbalance should be improved by either a reduction of phosphate absorption or an increased removal of phosphate. A reduction of phosphate absorption can be achieved by reducing the amount of phosphate in the diet or by the administration of phosphate binders. Unfortunately, these measures imply practical difficulties, for example, a lack of patient compliance or other side effects. When considering modifications of the hemodialysis treatment, an essential understanding of the kinetics of dialytic phosphate removal is mandatory. Phosphate is unevenly distributed in different compartments of the body. Only a very small amount of phosphate is present in the easily accessible plasma compartment. The major part of phosphate removed during hemodialysis originates from the cytoplasm of cells. A transfer from intracellular space to the plasma and further from the plasma to the dialysate is necessary. However, if we consider improvement to phosphate removal by dialysis procedures, full dialyzer clearance is effective in only the initial phase of the dialysis treatment. After this initial phase, the transfer rate for phosphate from the intracellular space to the plasma becomes the rate-limiting step for phosphate transport. Attempts to improve this transfer rate have recently been investigated by acidosis correction, but turned out not to be consistently successful. Furthermore, modifications of the treatment schedule have been described in

    Serum phosphate and vitamin D receptor activator regulate fibroblast growth factor 23 (FGF23), and iron may modulate FGF23 metabolism. The aim of the present study was to elucidate the effects of ferric citrate hydrate and lanthanum carbohydrate on serum FGF23 levels in hemodialysis patients. This prospective, open-label, multicenter study enrolled 60 patients on hemodialysis treated with lanthanum carbonate. Patients were randomly assigned to 2 groups: those switching from lanthanum carbonate to ferric citrate hydrate (ferric citrate group, n = 30) or those continuing lanthanum carbonate (control group, n = 30). Patients were monitored for 24 weeks. Endpoints included changes in FGF23, phosphate, and the dose of erythropoiesis stimulating agent (ESA), erythropoietin responsiveness index (ERI), and adverse events. FGF-23 levels were significantly lower in the ferric citrate group compared with the levels in the control group (change from baseline -6,160 vs. -1,118 pg/mL; p = 0.026). There were no significant changes in serum calcium, phosphate, and intact parathyroid hormone levels in either group. The ferric citrate group had significantly increased serum iron, ferritin, and transferrin saturation. Hemoglobin levels were significantly elevated, and the dose of ESA was significantly decreased in the ferric citrate group but not in the control group. ERI and the dose of intravenous saccharated ferric oxide were significantly lower in the ferric citrate group compared with those of the control group (p = 0.015 and p = 0.002). In patients on hemodialysis, 24-week treatment with ferric citrate hydrate resulted in significant reduction in FGF23 and ERI independently of serum phosphate level. © 2018 S. Karger AG, Basel.

    It is unknown whether regular patient-doctor contact (PDC) contributes to better outcomes for patients undergoing hemodialysis. Here, we analyzed the associations between frequency and duration of PDC during hemodialysis treatments with clinical outcomes among 24,498 patients from 778 facilities in the international Dialysis Outcomes and Practice Patterns Study (DOPPS). The typical facility PDC frequency, estimated by facility personnel, was high (more than once per week) for 55% of facilities, intermediate (once per week) for 24%, and low (less than once per week) for 21%. The mean ± SD estimated duration of a typical interaction between patient and physician was 7.7±5.6 minutes. PDC frequency and duration varied across DOPPS phases and countries; the proportion of facilities with high PDC frequency was 17% in the United States and 73% across the other countries. Compared with high PDC frequency, the adjusted hazard ratio (HR) for all-cause mortality was 1.06 (95% confidence interval [CI], 0.96 to 1.17) for intermediate PDC frequency and 1.11 (95% CI, 1.01 to 1.23) for low PDC frequency (P=0.03 for trend). Furthermore, each 5-minutes-shorter duration of PDC was associated with a 5% higher risk for death, on average (HR, 1.05; 95% CI, 1.01 to 1.09), adjusted for PDC frequency and other covariates. Multivariable analyses also suggested modest inverse associations between both PDC frequency and duration with hospitalization but not with kidney transplantation. Taken together, these results suggest that policies supporting more frequent and longer duration of PDC may improve patient outcomes in hemodialysis. PMID:23886592

    To determine hepatitis C virus (HCV) infection prevalence in each country of the Middle-East and the overall prevalence of the region. In this systematic review, we gathered all documents related to HCV infection prevalence among hemodialysis patients in 17 middle-east countries from April 2006 to March 2016. We selected only cross-sectional studies that had proper sampling and measurement methods as well as a valid statistical analysis. After screening of 7311 documents, 56 studies were selected reporting the prevalence of HCV infection among hemodialysis patients from 10 countries of the region. Seven countries including United Arab Emirates, Afghanistan, Qatar, Bahrain, Kuwait, Oman, Israel, and Cyprus did not have any relevant document; thus, their latest reports were just mentioned. We performed the meta-analysis and determined the prevalence rates for each country as well as the whole region. The overall HCV infection prevalence among hemodialysis patients in the region was reported to be 25.3%; Egypt and Syria had the highest reported rates while Iran and Lebanon had the lowest. Further investigations are still needed to provide more reliable databases, find main risk factors, and to improve diagnosis and treatment plans, particularly in higher prevalent countries. Controlling the prevalence and improving the management methods of HCV infection among hemodialysis patients are of a great concern in the Middle-East region.

    Hemodialysis patients experience an elevated risk of malnutrition associated with increased morbidity and mortality. Nocturnal hemodialysis (NHD) results in more effective removal of waste products and fluids. Therefore, diet and fluid restrictions are less restricted in NHD patients. However, it is ambiguous whether transition from conventional hemodialysis (CHD) to NHD leads to improved intake and nutritional status. We studied the effect of NHD on protein intake, laboratory indices of nutritional status, and body composition. Systematic review with meta-analysis. NHD patients. Systematic literature search from databases, Medline, Cinahl, EMBASE and The Cochrane Library, to identify studies reporting on nutritional status post-transition from CHD to NHD. Transition from CHD to NHD. Albumin, normalized protein catabolic rate (nPCR), dry body weight (DBW), body mass index (BMI), phase angle, protein intake, and energy intake. Systematic literature search revealed 13 studies comprising 282 patients that made the transition from CHD to NHD. Meta-analysis included nine studies in 229 patients. In control group controlled studies (n = 4), serum albumin increased significantly from baseline to 4-6 months in NHD patients compared with patients that remained on CHD (mean difference 1.3 g/l, 95% CI 0.02; 2.58, p = 0.05). In baseline controlled studies, from baseline to 4-6 months of NHD treatment, significant increases were ascertained in serum albumin (mean difference (MD) 1.63 g/l, 95% CI 0.73-2.53, p<0.001); nPCR (MD 0.16 g/kg/day; 95% CI 0.04-0.29, p = 0.01); protein intake (MD 18.9 g, 95% CI 9.7-28.2, p<0.001); and energy intake (MD 183.2 kcal, 95% CI 16.8-349.7, p = 0.03). Homogeneity was rejected only for nPCR (baseline versus 4-6 months). DBW, BMI, and phase angle did not significantly change. Similar results were obtained for comparison between baseline and 8-12 months of NHD treatment. Most studies had moderate sample sizes; some had incomplete dietary records

    The Iodine-131 (I-131) is a radioisotope used as a standard treatment for radioablation of thyroid remnants. Among thyroid cancer patients, the ones undergoing hemodialysis represent a specific group. The dose of I-131 is given orally to these patients, part of it is absorbed by the thyroid remnants and the rest of it, largely not incorporated, is excreted primarily by renal excretion. The use of a high dose of radioactivity in the process, and the inability of excretion, represents a high risk of exposure to the patient, medical staff and hemodialysis equipment. This work describes the procedure applied on the radioablationmore » therapy for thyroid cancer while receiving hemodialysis, minimizing the risks for the patient and the staff involved. This clinical procedure will establish the dosimetric measures, a plan on radiation protection and a treatment protocol for this specific type of patients.« less

    Previous studies show that serum bilirubin has potent antioxidant effect and is associated with protection from kidney damage and reduce cardiovascular events. The aim of this study was to examine the association of serum total bilirubin level and mortality in uremia patients who underwent hemodialysis. This is a nationwide retrospective long-term cohort study. Patients were registered in the Taiwan Renal Registry Data System (TWRDS) from 2005 to 2012. A total of 115,535 hemodialysis patients were surveyed and those with valid baseline total bilirubin (TB) data were enrolled. All-cause mortality was the primary outcome. A total of 47,650 hemodialysis patients followed for 27.6 ± 12 months, were divided into 3 groups according to different baseline serum total bilirubin levels (0.1-0.3, 0.3-0.7, 0.7-1.2 mg/dL). Mean age was 61.4 ± 13.6 years, 50% were male, 13% were hepatitis B carriers, and 20% were hepatitis C carriers. Primary outcome was the 3-year mortality. The TB level 0.7-1.2 mg/dL group had high mortality, statistically significant hazard ratio of mortality was 1.14 (crude HR, 95% 1.07-1.20, p < 0.01), and adjusted HR was 1.18 (model 1, 95% CI 1.11-1.25), 1.21 (model 2, 95% CI 1.14-1.29, p < 0.01), 1.44 (model 3, 95% CI 1.06-1.96, p < 0.01), respectively. Sensitivity test showed that after excluding 14,899 patients with hepatitis B or C, or abnormal liver function, the highest level of TB associated with higher significant mortality was still robust. In our study, high TB level is associated with mortality in uremia patients undergoing long-term hemodialysis, but further studies of the different effects of unconjugated or conjugated bilirubin on hemodialysis patients are needed.

    Pregnancies in hemodialysis patients are uncommon and difficult to study. Although the chance of a successful pregnancy and parturition in hemodialysis women has increased over the years, it still remains extremely low with a high maternal and fetal mortality and morbidity rate. We reported a case of successful pregnancy and parturition in a 22-year-old Chinese female in uremic stage of chronic renal failure and undergoing maintenance hemodialysis (three sessions a week) for 6 years. At the 22nd gestational week, she was diagnosed as pregnant by ultrasound, and started an enhanced hemodialysis routine (Five sessions a week). At the 32nd gestational week, she got hospitalized and received hemodialysis more frequently (seven sessions a week). Based on the initial diagnoses, including uremic stage of chronic renal failure, stage-3 hypertension, single pregnancy of 32nd gestational week, single umbilical artery and polyhydramnios, a drug therapy consisting of compound amino acid, fructosediphosphate sodium, 10% L-carnitine, erythropoietin, polyferose, amlodipine, isosorbidedinitrate, low-molecular weight-heparin, multivitamins and folic acid was given, and daily examination of the mother and fetus was performed. Under the joint efforts of various departments, the patient underwent caesarean section at the 34th gestational week due to progressive uterine contraction and gave birth to a female, well-being baby weighing 1470 g. It has been more than 3 years since the parturition. The mother has returned to the previous hemodialysis routine, and the child has been growing up healthily. Although pregnancy in hemodialysis patients is rare, with a high rate of risks. Patients could still gain a good outcome, if we intensify hemodialysis and enhance the collaboration between the patient, nephrologists, obstetricians, neonatologist, nutritionists, and other departments.

    In Pakistan, patients with chronic kidney disease (CKD) are commonly diagnosed at a late stage. There is little information about the refusal of hemodialysis by hospitalized CKD patients who need hemodialysis (HD) and reasons for acceptance and refusal among these patients. All patients with Stage V CKD who had medical indications to undergo HD and were hospitalized at a tertiary care facility over a six-month period were invited to participate in this study. Patients were surveyed regarding acceptance or refusing of HD and reasons for their decisions. Demographic, socioeconomic, and clinical characteristics of patients were compared between patients who accepted or refused HD. A total of 125 patients were included in the study. The mean age of the patients was 47.9 ±12.1 years. The mean duration of diagnosis of CKD was 2.5 ± 0.6 months. Of all patients, 72 (57.6%) agreed to do HD and 53 (42.4%) refused HD. Patients with arteriovenous fistula in place (27.1 vs. 9.1%, P 0.02) and those in the middle- or higher-income group (64.4% vs. 38.6%, p = 0.03) were more willing to undergo HD. Trust in doctor's advice (86.1%) was the most common reason for acceptance of HD. Frequency of HD per week (52.8%), lifelong and permanent nature of HD (50.9%), advice by family members or friends (37.7%), perception of poor quality of life on HD (35.8%), and fear of HD needles and complications during HD (33.9%) were the most common reasons for refusal. Refusal of HD is common among hospitalized CKD patients with medical indications to undergo HD, especially in lower income group.

    Hyperphosphatemia and poor nutritional status are associated with increased mortality. Lanthanum carbonate is an effective, calcium-free phosphate binder, but little is known about the long-term impact on mineral metabolism, nutritional status and survival. We extended the follow-up period of a historical cohort of 2292 maintenance hemodialysis patients that was formed in late 2008. We examined 7-year all-cause mortality according to the serum phosphate levels and nutritional indicators in the entire cohort and then compared the mortality rate of the 562 patients who initiated lanthanum with that of the 562 propensity score-matched patients who were not treated with lanthanum. During a mean ± SD follow-up of 4.9 ± 2.3 years, 679 patients died in the entire cohort. Higher serum phosphorus levels and lower nutritional indicators (body mass index, albumin and creatinine) were each independently associated with an increased risk of death. In the propensity score-matched analysis, patients who initiated lanthanum had a 23% lower risk for mortality compared with the matched controls. During the follow-up period, the serum phosphorus levels tended to decrease comparably in both groups, but the lanthanum group maintained a better nutritional status than the control group. The survival benefit associated with lanthanum was unchanged after adjustment for time-varying phosphorus or other mineral metabolism parameters, but was attenuated by adjustments for time-varying indicators of nutritional status. Treatment with lanthanum is associated with improved survival in hemodialysis patients. This effect may be partially mediated by relaxation of dietary phosphate restriction and improved nutritional status.

    Advanced age is a known risk factor for morbidity and mortality after coronary artery bypass grafting (CABG). Minimized extracorporeal circulation (MECC) has been shown to reduce the negative effects associated with conventional extracorporeal circulation (CECC). This trial assesses the impact of MECC on the outcome of elderly patients undergoing CABG. Eight hundred and seventy-five patients (mean age 78.35 years) underwent isolated CABG using CECC (n=345) or MECC (n=530). The MECC group had a significantly shorter extracorporeal circulation time (ECCT), cross-clamp time and reperfusion time and lower transfusion needs. Postoperatively, these patients required significantly less inotropic support, fewer blood transfusions, less postoperative hemodialysis and developed less delirium compared to CECC patients. In the MECC group, intensive care unit (ICU) stay was significantly shorter and 30-day mortality was significantly reduced [2.6% versus 7.8%; p<0.001]. In conclusion, MECC improves outcome in elderly patients undergoing CABG surgery. © The Author(s) 2015.

    The incidence of chronic kidney disease (CKD) is increasing rapidly. Diabetes mellitus (DM) is the most important cause of CKD. We studied the possible role of DM in CKD patients with respect to DNA damage, as assessed by the comet assay in 60 CKD patients (with or without DM) undergoing hemodialysis and in 26 controls. Effects of other factors, such as age, sex, hypertension, duration of hemodialysis, body mass index (BMI), and levels of hemoglobin (HB), intact parathormone (iPTH), and ferritin (FER), were also examined. Primary DNA damage measured by the comet assay was significantly higher in CKD patients than in controls. Among CKD patients, the following correlations were observed. (1) There was no difference in comet tail length or tail intensity between diabetic and non-diabetic individuals. (2) Age, sex, hemoglobin, hypertension, duration of hemodialysis, and ferritin levels affected neither tail length nor intensity. (3) BMI values above 25kg/m(2) and iPTH levels above 300pg/ml were associated with significantly greater comet tail length. Our results indicate that primary DNA damage is increased in CKD patients undergoing hemodialysis, compared to controls; however, DM had no additional effect. Copyright © 2016.

    Depressive symptoms and pain are common in patients receiving chronic hemodialysis, yet their effect on dialysis adherence, health resource utilization, and mortality is not fully understood. This study sought to characterize the longitudinal associations of these symptoms with dialysis adherence, emergency department (ED) visits, hospitalizations, and mortality. As part of a trial comparing symptom management strategies in patients receiving chronic hemodialysis, this study prospectively assessed depressive symptoms using the Patient Health Questionnaire 9, and pain using the Short-Form McGill Pain Questionnaire, monthly between 2009 and 2011. This study used negative binomial, Poisson, and proportional hazards regression to analyze the longitudinal associations of depressive symptoms and pain, scaled based on 5-point increments in symptom scores, with missed and abbreviated hemodialysis treatments, ED visits, hospitalizations, and mortality, respectively. Among 286 patients, moderate-to-severe depressive symptoms were identified on 788 of 4452 (18%) assessments and pain was reported on 3537 of 4459 (79%) assessments.

    Chronic hemodialysis patients experience accelerated atherosclerosis contributed to by dyslipidemia, inflammation, and an impaired antioxidant system. Vitamin E tocotrienols possess anti-inflammatory and antioxidant properties. However, the impact of dietary intervention with Vitamin E tocotrienols is unknown in this population. A randomized, double-blind, placebo-controlled, parallel trial was conducted in 81 patients undergoing chronic hemodialysis. Subjects were provided daily with capsules containing either vitamin E tocotrienol-rich fraction (TRF) (180 mg tocotrienols, 40 mg tocopherols) or placebo (0.48 mg tocotrienols, 0.88 mg tocopherols). Endpoints included measurements of inflammatory markers (C-reactive protein and interleukin 6), oxidative status (total antioxidant power and malondialdehyde), lipid profiles (plasma total cholesterol, triacylglycerols, and high-density lipoprotein cholesterol), as well as cholesteryl-ester transfer protein activity and apolipoprotein A1. TRF supplementation did not impact any nutritional, inflammatory, or oxidative status biomarkers over time when compared with the baseline within the group (one-way repeated measures analysis of variance) or when compared with the placebo group at a particular time point (independent t-test). However, the TRF supplemented group showed improvement in lipid profiles after 12 and 16 weeks of intervention when compared with placebo at the respective time points. Normalized plasma triacylglycerols (cf baseline) in the TRF group were reduced by 33 mg/dL (P=0.032) and 36 mg/dL (P=0.072) after 12 and 16 weeks of intervention but no significant improvement was seen in the placebo group. Similarly, normalized plasma high-density lipoprotein cholesterol was higher (P<0.05) in the TRF group as compared with placebo at both week 12 and week 16. The changes in the TRF group at week 12 and week 16 were associated with higher plasma apolipoprotein A1 concentration (P<0.02) and lower cholesteryl

    Hyperphosphatemia is common among patients with CKD stage 5D and is associated with morbidity and mortality. Current guidelines recommend lowering serum phosphate concentrations toward normal. Tenapanor is a minimally absorbed small molecule inhibitor of the sodium/hydrogen exchanger isoform 3 that functions in the gut to reduce sodium and phosphate absorption. This randomized, double-blind, placebo-controlled trial assessed the effects of tenapanor on serum phosphate concentration in patients with hyperphosphatemia receiving hemodialysis. After a 1- to 3-week washout of phosphate binders, we randomly assigned 162 eligible patients (serum phosphate =6.0 to <10.0 mg/dl and a 1.5-mg/dl increase from before washout) to one of six tenapanor regimens (3 or 30 mg once daily or 1, 3, 10, or 30 mg twice daily) or placebo for 4 weeks. The primary efficacy end point was change in serum phosphate concentration from baseline (randomization) to end of treatment. In total, 115 patients (71%) completed the study. Mean serum phosphate concentrations at baseline (after washout) were 7.32–7.92 mg/dl for tenapanor groups and 7.87 mg/dl for the placebo group. Tenapanor provided dose-dependent reductions in serum phosphate level from baseline (least squares mean change: tenapanor =0.47–1.98 mg/dl; placebo =0.54 mg/dl; P=0.01). Diarrhea was the most common adverse event (tenapanor =18%–68%; placebo =12%) and frequent at the highest tenapanor doses. In conclusion, tenapanor treatment resulted in statistically significant, dose-dependent reductions in serum phosphate concentrations in patients with hyperphosphatemia receiving hemodialysis. Additional studies are required to clarify the optimal dosing of tenapanor in patients with CKD-related hyperphosphatemia. PMID:28159782

    Uremic pruritus (UP) is a significant complication in ESRD patients and substantially impairs their quality of life. UP is considered to be a skin manifestation of chronic inflammation. Because sericin can suppress the release of pro-inflammatory cytokines, the purpose of this study was to investigate the short-term safety and efficacy of sericin cream for treating UP in hemodialysis patients. This study used a double-blind design to investigate the effects of random topical administration of sericin cream and cream base (placebo) on either the right or left extremities of hemodialysis patients for 6 weeks. Skin hydration, irritation and pigmentation were evaluated every 2 weeks using Skin Diagnostic SD27. The visual analog scale for itching was also evaluated every 2 weeks, and the Kidney Disease Quality of Life Short Form was performed on the day of each patient's enrollment and after 6 weeks of treatment. Fifty dialysis patients were enrolled, 47 of which completed the study. The hydration of the skin of the patients' extremities increased significantly after administration of sericin cream; significant differences were found between sericin treatment and control after 6 weeks of treatment (p = 0.041 for arms and p = 0.022 for legs, respectively). Moreover, a significant difference was also found in skin irritation between the two treatments (p = 0.013 for arms and p = 0.027 for legs, respectively). At the end of the study, the skin pigmentation level was significantly reduced on both the arms (p = 0.032) and legs (p = 0.021) of the sericin-treated side compared with the side treated with cream base. The mean itching score decreased significantly from moderate to severe at the time of enrollment to mild pruritus after 6 weeks of treatment (p = 0.002). A better quality of life was found in all domains tested although statistically significant differences before and after treatment was found only in the patients' pain scores, the effect

    An effective home hemodialysis program critically depends on adequate hub facilities and support functions and on transparent and accountable organizational processes. The likelihood of optimal service delivery and patient care will be enhanced by fit-for-purpose facilities and implementation of a well-considered governance structure. In this article, we describe the required accommodation and infrastructure for a home hemodialysis program and a generic organizational structure that will support both patient-facing clinical activities and business processes. © 2015 International Society for Hemodialysis.

    Cytokines are likely involved in hemodialysis-associated complications such as immunodeficiency and beta 2 microglobulin amyloidosis. Because transforming growth factors beta (TGF beta) exert immunosuppressive effects on lymphocytes, down-modulate monocyte functions, and promote fibrosis, we hypothesize that they participate in the deleterious effects of hemodialysis. We investigated the production of TGF beta 1 and TGF beta 2 by monocytes from controls and patients dialyzed with high-flux cellulose triacetate (CT) and polyacrylonitrile (PAN) membranes. The detection of both TGF beta s required an acidification step, suggesting that they are secreted as latent complexes. The spontaneous production of TGF beta 1 and TGF beta 2 was significantly higher in patients dialyzed with CT or PAN than in controls, but the oversecretion of TGF beta 1 was more sustained in CT-treated patients than in PAN-dialyzed patients. The production of interleukin-6 (IL-6) was increased in both patient groups as compared with controls. In contrast to TGF beta 1, the increase was greater in PAN-treated patients than in CT-treated patients, and the release of tumor necrosis factor alpha (TNF alpha) was increased only in PAN-treated patients. Taken together, our results show that hemodialysis is associated with the oversecretion of monocyte cytokines. Moreover, the type of dialysis membrane specifically affects the balance between the secretion of suppressive cytokines such as TGF beta and that of inflammatory cytokines such as IL-6 and TNF alpha.

    The purpose of this study was to determine the influence of patient-reported medication adherence and phosphorus-related knowledge on phosphorus control and pharmacy-reported adherence to phosphorus binding medication among patients on maintenance hemodialysis. Retrospective, cross-sectional cohort study. Seventy-nine hemodialysis patients (mean age 64.2 years, SD = 14 years; 46.8% female) in a stand-alone hemodialysis unit within an integrated learning healthcare system. Ten percent (10%) of subjects were Caucasian, 42% Latino, 19% African American, and 29% Asian. Forty-eight percent had diabetes; 72% had BMI ≥ 30. Inclusion criteria included the provision of survey data and having medication refill data available in the pharmacy system. 77.2% had mean phosphorus levels ≤ 5.5 mg/dL; 22.8% had mean phosphorus levels > 5.5 mg/dL. Subjects were administered the 8-item Morisky Medication Adherence Scale (MMAS-8) and also reported on their phosphorus-related knowledge. Phosphorus levels within an adequate range. The mean serum phosphorus level was 4.96 mg/dL (SD = 1.21). In the well-controlled group, mean phosphorus was 4.44 mg/dL (SD = 0.76). In the poorly controlled group, mean phosphorus was 6.69 mg/dL (SD = 0.74). A total of 61% of patients reported at least some unintentional medication nonadherence, and 48% reported intentional medication nonadherence. Phosphorus-specific knowledge was low, with just under half of patients reporting that they could not name two high-phosphorus foods or identify a phosphorus-related health risk. Phosphorus binder-related nonadherence was substantially higher in the uncontrolled than the controlled group. Adjusting for age, individuals with poorer self-reported binder adherence were less likely to have controlled phosphorus levels (odds ratio = 0.71, P = .06). Phosphorus-related non-adherence, but not low phosphorus-specific knowledge, was associated with poorer phosphorus control. Such findings provide important information

    Background and objectives In Canada, approximately 17% of patients use an arteriovenous access (fistula or arteriovenous graft) at commencement of hemodialysis, despite guideline recommendations promoting its timely creation and use. It is unclear if this low pattern of use is attributable to the lack of surgical creation or a high nonuse rate. Design, setting, participants, & measurements Using large health care databases in Ontario, Canada, a population-based cohort of adult patients (≥18 years old) who initiated hemodialysis as their first form of RRT between 2001 and 2010 was studied. The aims were to (1) estimate the proportion of patients who had an arteriovenous access created before starting hemodialysis and the proportion who successfully used it at hemodialysis start, (2) test for secular trends in arteriovenous access creation, and (3) estimate the effect of late nephrology referral and patient characteristics on arteriovenous access creation. Results There were 17,183 patients on incident hemodialysis. The mean age was 65.8 years, 60% were men, and 40% were referred late to a nephrologist; 27% of patients (4556 of 17,183) had one or more arteriovenous accesses created, and the median time between arteriovenous access creation and hemodialysis start was 184 days. When late referrals were excluded, 39% of patients (4007 of 10,291) had one or more arteriovenous accesses created, and 27% of patients (2724 of 10,291) used the arteriovenous access. Since 2001, there has been a decline in arteriovenous access creation before hemodialysis initiation. Women, higher numbers of comorbidities, and rural residence were consistently associated with lower rates of arteriovenous access creation. These results persisted even after removing patients with <6 months nephrology care or who had AKI 6 months before starting hemodialysis.

    Cardiovascular calcification (CVC) in hemodialysis patients (HDP) causes cardiovascular pathology. Up until now very few drugs and therapeutic interventions have been able to reduce cardiovascular calcium deposits in hemodialysis patients and the process requires more than a year. Our idea in this study was to test 2 calcium binders--sodium thiosulfate (STS) and dinatrium ethylene diamine tetraacetic acid (DNEDTA)--for prevention and treatment of cardiovascular calcification of hemodialysis patients, using both substances not as an intravenous infusion but by adding them to the liquid bicarbonate part of the dialysis fluid. 6 HDPs were treated with sodium thiosulphate (STS), 6 with dinatrium ethylene diamine tetraacetic acid (DNEDTA), and 6 patients served as controls. Electrolytes, liver function, markers of inflammation, oxidative stress, bone metabolism, spiral computed tomography (SCT) of coronary CVC and bone densitometry were performed twice (start and end of the study). Starting blood parameters were similar to the end (STS group). No toxic or side effects from STS were observed. Initially in the DNEDTA group all the patients had vomiting so we excluded DNEDTA from the study. SCT found a significant reduction of calcification in 4 patients (STS group) and retardation in 2 patients comparatively to controls. The first results are hopeful, but the number of the patients was small, so we are enlarging the enrollment in the expectation of corroborating our results soon.

    Background: Anemia of chronic kidney disease is associated with adverse outcomes and a reduced quality of life. Erythropoiesis-stimulating agents (ESAs) have improved anemia management, and 2 agents are available in Canada, epoetin alfa (EPO) and darbepoetin alfa (DA). EPO and DA are considered equally effective in achieving target hemoglobin (Hb), but it is not clear whether there is a cost difference. There have been few head-to-head comparisons; most published studies are observational switch studies. Objective: To compare the cost of DA and EPO and to determine the dose conversion ratio over a 12-month period. Design: Randomized controlled trial. Setting: Canadian outpatient hemodialysis center. Patients: Eligible patients were adult hemodialysis patients requiring ESA therapy. Measurements: The primary outcome was ESA cost (Can$) per patient over 12 months. Secondary outcomes included the dose conversion ratio, deviation from target ranges in anemia indices, iron dose and cost, and time and number of dose changes. Methods: An open-label randomized controlled trial of intravenous (IV) DA versus EPO was conducted in 50 hemodialysis patients. Participants underwent a minimum 6-week run-in phase followed by a 12-month active study phase. ESA and iron were dosed using a study algorithm. Results: The median cost was $4179 (interquartile range [IQR]: $2416-$5955) for EPO and $2303 (IQR: $1178-$4219) for DA with a difference of $1876 (P = .02). The dose conversion ratio was 280:1 (95% confidence interval [CI]: 197-362:1) at the end of the run-in phase, 360:1 (95% CI: 262-457:1) at the 3-month point of the active phase, and 382:1 (95% CI: 235-529:1) at the 6-month point of the active phase. There were no significant differences between the 2 groups in weekly iron dose, Hb, serum ferritin, or transferrin saturation. The number of dose changes and the time to Hb stability were similar. Limitations: Results may not be generalizable to hemodialysis units without algorithm

    Hemodialysis (HD) adequacy is currently assessed using normalized urea clearance (Kt/V), although scaling based on Watson volume (V) may disadvantage women and men with low body weight. Alternative scaling factors such as resting energy expenditure and high metabolic rate organ mass have been suggested. The relationship between such factors and uremic toxin generation has not been established. We aimed to study the relationship between body size, energy metabolism, and urea generation rate. A cross-sectional cohort of 166 HD patients was studied. Anthropometric measurements were carried on all. Resting energy expenditure was measured by indirect calorimetry, fat-free mass by bio-impedance and total energy expenditure by combining resting energy expenditure with a questionnaire-derived physical activity data. High metabolic rate organ mass was calculated using a published equation and urea generation rate using formal urea kinetic modeling. Metabolic factors including resting energy expenditure, total energy expenditure and fat-free mass correlated better with urea generation rate than did Watson volume. Total energy expenditure and fat-free mass (but not Watson Volume) were independent predictors of urea generation rate, the model explaining 42% of its variation. Small women (patients and hence may impact on minimum dialysis requirements. Small women generate relatively more small solute toxins than other groups and thus may have a higher relative need for dialysis. © 2013 The Authors. Hemodialysis

    Background and objectives Fractures are a major source of morbidity and mortality in patients receiving dialysis. We sought to determine whether rates of fractures and tendon ruptures vary geographically. Design, setting, participants, & measurements Data from the US Renal Data System were used to create four yearly cohorts, 2007–2010, including all eligible prevalent patients on hemodialysis in the United States on January 1 of each year. A secondary analysis comprising patients in a large dialysis organization conducted over the same period permitted inclusion of patient-level markers of mineral metabolism. Patients were grouped into 10 regions designated by the Centers for Medicare and Medicaid Services and divided by latitude into one of three bands: south, <35°; middle, 35° to <40°; and north, ≥40°. Poisson regression was used to calculate unadjusted and adjusted region–level rate ratios for events. Results Overall, 327,615 patients on hemodialysis were included. Mean (SD) age was 61.8 (15.0) years old, 52.7% were white, and 55.0% were men. During 716,962 person-years of follow-up, 44,014 fractures and tendon ruptures occurred, the latter being only 0.3% of overall events. Event rates ranged from 5.36 to 7.83 per 100 person-years, a 1.5-fold rate difference across regions. Unadjusted region–level rate ratios varied from 0.83 (95% confidence interval, 0.81 to 0.85) to 1.20 (95% confidence interval, 1.18 to 1.23), a 1.45-fold rate difference. After adjustment for a wide range of case mix variables, a 1.33-fold variation in rates remained. Rates were higher in north and middle bands than the south (north rate ratio, 1.18; 95% confidence interval, 1.13 to 1.23; middle rate ratio, 1.13; 95% confidence interval, 1.10 to 1.17). Latitude explained 11% of variation, independent of region.

    To evaluate the use of the emergency department (ED) by elderly patients, their non-urgent visits and the prevalence of main disease for ED visits. This cross-sectional study was conducted on patients aged 65 years and over who visited the ED of a tertiary care university hospital in Turkey between January 2015 and January 2016 retrospectively. A total of 36,369 elderly patients who visited the ED were included in the study. The rate of ED visits by elderly patients was higher than their representation within the general population (p < 0.001). While the rate of elderly patients visiting polyclinics was 15.8%, the rate of elderly patients visiting the ED was 24.3% (p < 0.001). For both genders, the rates of ED visits for patients between 65 and 74 years old was higher than for other elderly age groups (p < 0.001). The prevalence of upper respiratory tract infection (URTI) was the highest within the elderly population (17.5%, CI: 17.1-17.9). The proportion of ED visits for non-urgent conditions was 23.4%. Most of the ED visits were during the non-business hours (51.1%), and they were highest in the winter season (25.9%) and in January (10.2%). The hospitalization rate was 9.4%, and 37.9% of hospitalized patients were admitted to intensive care units. The proportion of ED visits by elderly patients was higher than their representation within the general population. Elderly patients often visited the ED instead of a polyclinic. The rate of inappropriate ED use by elderly patients in this hospital was higher than in other countries.

    Patients with end stage renal diseases (ESRD) undergoing hemodialysis (HD) have high morbidity and mortality due to multiple causes; one of which is dramatically higher fall rates than the general population. In spite of the multiple efforts aiming to decrease the high mortality and improve quality of life in ESRD patients, limited success has been achieved. If adequate interventions for fall prevention are to be achieved, the functional and mobility mechanisms consistent with falls in this population must be understood. Human movements such as sit-to-walk (STW) tasks are clinically significant, and analysis of these movements provides a meaningful evaluation of postural and locomotor performance in elderly patients with functional limitations indicative of fall risks. In order to assess the effects of HD therapy on fall risks, 22 sessions of both pre- and post-HD measurements were obtained in six ESRD patients utilizing customized inertial measurement units (IMU). IMU signals were denoised using ensemble empirical mode decomposition and Savistky-Golay filtering methods to detect relevant events for identification of STW phases. The results indicated that patients were slower to get out of the chair (as measured by trunk flexion angular accelerations, time to peak trunk flexion, and overall STW completion time) following the dialysis therapy session. STW is a frequent movement in activities of daily living, and HD therapy may influence the postural and locomotor control of these movements. The analysis of STW movement may assist in not only assessing a patient's physical status, but in identifying HD-related fall risk as well. This preliminary study presents a non-invasive method of kinematic measurement for early detection of increased fall risk in ESRD patients using portable inertial sensors for out-patient monitoring. This can be helpful in understanding the pathogenesis better, and improve awareness in health care providers in targeting interventions to

    Medication adherence was assessed in 89 patients on hemodialysis (HD) at the King Abdul Aziz Medical City using an Arabic version of the Morisky Medication Adherence Scale (MASS-8). The results of the study revealed that 31.46% and 40.45% of the participants showed low and medium adherence, respectively, while 28.09% showed high medication adherence. Accordingly, 71.91% of the patients visiting the dialysis unit were considered medication non-adherent. While being of older age (P = 0.012), being married (P = 0.012) increased the level of adherence, being of medium level of education (P = 0.024) decreased adherence levels. On the other hand, gender, presence of a care-giver, number of members in the household and employment status seems to have no effect on the level of medication adherence. These results call upon the practitioners in HD units to develop intervention programs that can increase the level of medication adherence.

    Carnitine deficiency is commonly seen in dialysis patients. This study assessed the association dialysis and pediatric patients' characteristics with plasma carnitines levels. Plasma carnitine concentrations were measured by tandem mass spectrometry in 46 children on hemodialysis or peritoneal dialysis. The total carnitine, free carnitine (FC), and L-acyl carnitine (AC) levels of 40 µmol/L and less, less than 7 µmol/L, and less than 15 µmol/L were defined low, respectively. An FC less than 20 µmol/L and an AC/FC ratio greater than 0.4 were considered as absolute and relative carnitine deficiencies. The correlation between carnitines levels and AC/FC ratio and age, duration of dialysis, characteristics of dialysis, and blood urea nitrogen and serum albumin concentrations were assessed. Absolute carnitine deficiency, low total carnitine, and low AC concentrations were found in 66.7%, 82.6%, and 51% of the patients, respectively. All of the patients had relative carnitine deficiency. Carnitine measurements were not significantly different between the hemodialysis and peritoneal dialysis groups. More severe relative carnitine deficiency was found in those with lower blood urea nitrogen levels and those on peritoneal dialysis. No linear correlation was found between carnitine levels and age, duration of dialysis, characteristics of dialysis, serum albumin level, or blood urea nitrogen level. Absolute and relative carnitine deficiencies are common among children on dialysis. Patients with lower blood urea nitrogen levels and peritoneal dialysis patients are more prone to severe relative carnitine deficiency.

    Central venous catheter (CVC) use is associated with increased mortality and complications in hemodialysis recipients. Although prevalent CVC use has decreased, incident use remains high. To examine characteristics associated with CVC use at initial dialysis, specifically looking at proteinuria as a predictor of interest. Retrospective cohort of 918 hemodialysis recipients from Kaiser Permanente Northwest who started hemodialysis from January 1, 2004, to January 1, 2014. Multivariable logistic regression was used to examine an association of proteinuria with the primary outcome of CVC use. More than one-third (36%) of patients in our cohort started hemodialysis with an arteriovenous fistula, and 64% started with a CVC. Proteinuria was associated with starting hemodialysis with a CVC (likelihood ratio test, p < 0.001) after adjustment for age, peripheral vascular disease, congestive heart failure, diabetes, sex, race, and length of predialysis care. However, on pairwise comparison, only patients with midgrade proteinuria (0.5-3.5 g) had lower odds of starting hemodialysis with a CVC (odds ratio = 0.39, 95% confidence interval = 0.24-0.65). Proteinuria was associated with use of CVC at initial hemodialysis. However, a graded association did not exist, and only patients with midgrade proteinuria had significantly lower odds of CVC use. Our findings suggest that proteinuria is an explanatory finding for CVC use but may not have pragmatic value for decision making. Patients with lower levels of proteinuria may have a higher risk of starting dialysis with a CVC.

    Advanced age is one of the factors that increase mortality in intensive care. Sepsis and multi-organ failure are likely to further increase mortality in elderly patients.We compared the characteristics and outcomes of septic elderly patients (> 65 years) with younger patients (≤ 65 years) and identified factors during the first 24 hours of presentation that could predict mortality in elderly patients. This study was conducted in a Level III intensive care unit with a case mix of medical and surgical patients excluding cardiac and neurosurgical patients.We performed a retrospective review of all septic patients admitted to our ICU between July 2004 and May 2007. In addition to demographics and co-morbidities, physiological and laboratory variables were analysed to identify early predictors of mortality in elderly patients with sepsis. Of 175 patients admitted with sepsis, 108 were older than 65 years. Elderly patients differed from younger patients with regard to sex, temperature (37.2°C VS 37.8°C p < 0.01), heart rate, systolic blood pressure, pH, HCO3, potassium, urea, creatinine, APACHE III and SAPS II. The ICU and hospital mortality was significantly higher in elderly patients (10.6% Vs 23.14% (p = 0.04) and 19.4 Vs 35.1 (p = 0.02) respectively). Elderly patients who died in hospital had a significant difference in pH, HCO3, mean blood pressure, potassium, albumin, organs failed, lactate, APACHE III and SAPS II compared to the elderly patients who survived while the mean age and co-morbidities were comparable. Logistic regression analysis identified temperature (OR [per degree centigrade decrease] 0.51; 95% CI 0.306- 0.854; p = 0.010) and SAPS II (OR [per point increase]: 1.12; 95% CI 1.016-1.235; p = 0.02) during the first 24 hours of admission to independently predict increased hospital mortality in elderly patients.

    End-stage chronic kidney disease (CKD) requiring dialysis affects the quality of life sometimes more severely than other chronic diseases, such as rheumatoid arthritis, heart failure, coronary artery disease, and chronic obstructive pulmonary disease, exerting a negative effect on the energy and vitality levels, limiting social interactions, and hindering psychic health. To evaluate the quality of life of patients with CKD on hemodialysis in a public Brazilian Amazonian hospital. Data were collected through interview based on the Brazilian version of the SF-36 questionnaire. The study was conducted on 50 patients (mean age, 48 ± 16 years; mean hemodialysis time, 3 ± 2.9 years). The most affected domain was role limitations due to physical health, with a mean score of 36 ± 36, and 58% of the patients in the lowest quartile, while mental health and social functioning were relatively preserved, with most patients in the highest quartile. Men obtained poorer scores than women did for role limitations due to physical health and vitality. Age correlated negatively with physical functioning. Patients on hemodialysis for more than one year had better scores in the social functioning domain, with a positive correlation between dialysis time and physical functioning. The domains assessed were globally impaired in the population studied, especially regarding role limitations due to physical health, suggesting that chronic disease with prolonged treatment has a negative influence on those domains.

    Awake-craniotomy allows maximal tumor resection, which has been associated with extended survival. The feasibility and safety of awake-craniotomy and the effect of extent of resection on survival in the elderly population has not been established. The aim of this study was to compare surgical outcome of elderly patients undergoing awake-craniotomy to that of younger patients. Outcomes of consecutive patients younger and older than 65 years who underwent awake-craniotomy at a single institution between 2003 and 2010 were retrospectively reviewed. The groups were compared for clinical variables and surgical outcome parameters, as well as overall survival. A total of 334 young (45.4 ± 13.2 years, mean ± SD) and 90 elderly (71.7 ± 5.1 years) patients were studied. Distribution of gender, mannitol treatment, hemodynamic stability, and extent of tumor resection were similar. Significantly more younger patients had a better preoperative Karnofsky Performance Scale score (>70) than elderly patients (P = 0.0012). Older patients harbored significantly more high-grade gliomas (HGG) and brain metastases, and fewer low-grade gliomas (P < 0.0001). No significantly higher rate of mortality, or complications were observed in the elderly group. Age was associated with increased length of stay (4.9 ± 6.3 vs. 6.6 ± 7.5 days, P = 0.01). Maximal extent of tumor resection in patients with HGG was associated with prolonged survival in the elderly patients. Awake-craniotomy is a well-tolerated and safe procedure, even in elderly patients. Gross total tumor resection in elderly patients with HGG was associated with prolonged survival. The data suggest that favorable prognostic factors for patients with malignant brain tumors are also valid in elderly patients.

    Baroreflex failure syndrome is a rare disorder which causes labile blood pressure, headache, flushing, diaphoresis and emotional lability. It is caused by history of trauma or radiotherapy in the cervical legion, bilateral carotid-body tumor or resection of glossopharyngeal nerve. We experienced a case of hemodialysis patient who had difficulty in controlling blood pressure during dialysis because of his baroreflex failure syndrome and successfully controlled his blood pressure by adjusting dialysate temperature. We report a case of a 68-year-old CKD5 patient who had difficulty in hemodialysis treatment because of severe fluctuations in blood pressure with hypertensive attacks and hypotensive episodes which caused him a severe discomfort. His dialysis treatment was started in 2010 and since that time baroreflex failure syndrome has been suspected because of his clinical manifestations and history of radiotherapy in the cervical region for his lingual cancer in 1994. Baroreflex failure syndrome is diagnosed by symptoms and cold stressor test. We performed a cold stressor test on an experimental baroreflex failure syndrome mouse and induced a significant elevation of blood pressure. From this experimental finding of model mouse, we changed the patients dialysate temperature between 34-38° according to his change in blood pressure though 80-240 mmHg. From this attempt, his blood pressure was successfully controlled between 100-180 mmHg and he was able to continue hemodialysis without any discomfort. In our case, environmental stimulation such as temperature change modified the patients fluctuating blood pressure. Change of dialysate temperature could be an option for controlling the unstable blood pressure due to baroreflex failure syndrome.

    Early onset acidosis from mitochondrial toxicity can be observed in massive acetaminophen poisoning prior to the development of hepatotoxicity. In this context, the efficacy of acetylcysteine to reverse mitochondrial toxicity remains unclear and hemodialysis may offer prompt correction of acidosis. Unfortunately, toxicokinetics of acetaminophen and acetylcysteine during extracorporeal treatments hemodialysis have seldom been described. An 18-year-old woman presented to the emergency department 60 minutes after ingestion of 100 g of acetaminophen, and unknown amounts of ibuprofen and ethanol. Initial assessment revealed an agitated patient. Her mental status worsened and she required intubation for airway protection. Investigations showed metabolic acidosis with lactate peaking at 8.6 mmol/L. Liver and coagulation profiles remained normal. Acetaminophen concentration peaked at 981 μg/ml (6496 μmol/L). Pending hemodialysis, the patient received 100 g of activated charcoal and an acetylcysteine infusion at 150 mg/kg over 1 hour, followed by 12.5 mg/kg/h for 4 hours. During hemodialysis, the infusion was maintained at 12.5 mg/kg/h to compensate for expected removal before it was decreased to 6.25 mg/kg for 20 hours after hemodialysis. The patient rapidly improved during hemodialysis and was discharged 48 hours post-admission. The acetaminophen elimination half-life was 5.2 hours prior to hemodialysis, 1.9-hours during hemodialysis and 3.6 hours post hemodialysis. The acetaminophen and acetylcysteine clearances by A-V gradient during hemodialysis were 160.4 ml/min and 190.3 ml/min, respectively. Hemodialysis removed a total of 20.6 g of acetaminophen and 17.9 g of acetylcysteine. This study confirms the high dialyzability of both acetaminophen and acetylcysteine. Hemodialysis appears to be a beneficial therapeutic option in cases of massive acetaminophen ingestion with coma and lactic acidosis. Additionally, these results

    Free-living amoebae (FLA) of the genus Acanthamoeba are opportunistic pathogenic agents able to cause life-threatening infections in immunosuppressed patients. Chronic kidney disease impairs adaptive and innate immunity. Thus, patients with chronic kidney disease are prone to opportunistic infections by potentially pathogenic FLA. Therefore, in the present study, the investigation of Acanthamoeba genotypes isolated from the oral cavity of hemodialysis patients of reference hospitals in Iran was aimed, using both morphology and molecular (sequence-based analysis) tools. Furthermore, classification of the strains at the genotype level was performed on the basis of differences in the diagnostic fraction 3 (DF3) region of the 18S rRNA gene. The pathogenic potential of the isolated amoebae was also determined using thermotolerance and osmotolerance assays. Out of the 187 oral cavity samples investigated, nine (4.8%) were positive for FLA. DNA sequencing of the ASA.A1 region of the 18S rRNA gene revealed that the isolated strains belonged to the Acanthamoeba T1 and T4 genotypes. Genotype T1 was isolated for the first time from a patient in Iran. Interestingly, the T1 strain (AN2 strain) exhibits a high pathogenic potential in tolerance assays. The pathogenicity assay revealed that five strains were able to grow at high temperatures (37-40 °C) and high osmolarity (0.5 and 1 M D-mannitol) conditions; thus, they were considered as potentially pathogenic strains. Moreover, two of the patients were positive for Vermamoeba genus. The present study is the first report of genotype T1 isolation in Iran and the first to identify the occurrence of Acanthamoeba and Vermamoeba genera in patients undergoing hemodialysis worldwide. Monitoring hemodialysis and renal failure patients should be a priority for possible control of Acanthamoeba and other FLA-related diseases.

    Protein-Energy Wasting (PEW) is a pathological condition of renal patients with advanced Chronic Kidney Disease characterized by a progressive reduction of energy and protein assets. Nutritional status assessment, especially for what concerns muscle mass, is essential for both the identification of patients at risk for the development of PEW, as well as monitoring the effects of nutritional interventions. Ultrasound methods are easily applicable at the bedside for quantitative assessment of skeletal muscle. The present study was aimed at evaluating quadriceps rectus femoris thickness (QRFT) and quadriceps vastus intermedius thickness (QVIT) in patients on chronic hemodialysis. This was a prospective observational study. Three groups of adult patients were studied: young healthy subjects, well-nourished hospitalized patients with normal renal function, and End-Stage Renal Disease patients on hemodialysis (ESRD-HD). QRFT and QVIT were measured at two sites bilaterally (8 measures/patient) and were compared between groups, and also between subgroups of ESRD-HD patients stratified on the basis of conventional nutritional status parameters. We enrolled 35 healthy subjects, 30 hospitalized patients, and 121 ESRD-HD patients on hemodialysis. QRFT and QVIT of ESRD patients on hemodialysis were lower than those of both control groups (P < 0.001). After stratifying ESRD patients into subgroups based on nutritional variable cut-offs commonly used to define PEW in this clinical setting (BMI [≥ 23 vs <23 kg/m 2 ], albumin [≥3.8 vs <3.8 g/dL]) and malnutrition inflammation score (MIS) status (<6 vs ≥6), QRFT and QVIT of patients with worse nutritional status were significantly lower than those of well-nourished ESRD-HD patients (P value range: <0.001 to <0.05). Skeletal muscle ultrasound is a simple and easily applicable bedside technique in the dialysis units, and could represent an adequate tool for the identification of patients with reduced muscle mass.

    Larger weight gain and higher ultrafiltration rates have been associated with poorer outcomes among patients on dialysis. Dietary restrictions reduce fluid-related risk; however, adherence is challenging. Alternative fluid mitigation strategies include treatment time extension, more frequent dialysis, adjunct peritoneal dialysis, and wearable ultrafiltration devices. No data regarding patient preferences for fluid management exist. A survey was designed, tested, and administered to assess patient-stated preferences regarding fluid mitigation. A written survey concerning fluid-related symptoms, patient and treatment characteristics, and fluid management preferences was developed. The cross-sectional survey was completed by 600 patients on hemodialysis at 18 geographically diverse ambulatory facilities. Comparisons of patient willingness to engage in volume mitigation strategies across fluid symptom burden, dietary restriction experience, and patient characteristics were performed. Final analyses included 588 surveys. Overall, if allowed to liberalize fluid intake, 44.6% of patients were willing to extend treatment time by 15 minutes. Willingness to extend treatment time was incrementally less for longer treatment extensions; 12.2% of patients were willing to add a fourth weekly treatment session, and 13.5% of patients were willing to participate in nocturnal dialysis three nights per week. Patients more bothered by their fluid restrictions (versus less bothered) were more willing to engage in fluid mitigation strategies. Demographic characteristics and symptoms, such as cramping and dyspnea, were not consistently associated with willingness to engage in the proposed strategies. More than 25% of patients were unsure of their dry weights and typical interdialytic weight gains. Patients were generally averse to treatment time extension>15 minutes. Patients more bothered (versus less bothered) by their prescribed fluid restrictions were more willing to engage in volume

    Adequately powered studies directly comparing hard clinical outcomes of darbepoetin alfa (DPO) versus epoetin alfa (EPO) in patients undergoing dialysis are lacking. Observational, registry-based, retrospective cohort study; we mimicked a cluster-randomized trial by comparing mortality and cardiovascular events in US patients initiating hemodialysis therapy in facilities (almost) exclusively using DPO versus EPO. Nonchain US hemodialysis facilities; each facility switching from EPO to DPO (2003-2010) was matched for location, profit status, and facility type with one EPO facility. Patients subsequently initiating hemodialysis therapy in these facilities were assigned their facility-level exposure. DPO versus EPO. All-cause mortality, cardiovascular mortality; composite of cardiovascular death, nonfatal myocardial infarction (MI), and nonfatal stroke. Unadjusted and adjusted HRs from Cox proportional hazards regression models. Of 508 dialysis facilities that switched to DPO, 492 were matched with a similar EPO facility; 19,932 (DPO: 9,465 [47.5%]; EPO: 10,467 [52.5%]) incident hemodialysis patients were followed up for 21,918 person-years during which 5,550 deaths occurred. Almost all baseline characteristics were tightly balanced. The demographics-adjusted mortality HR for DPO (vs EPO) was 1.06 (95% CI, 1.00-1.13) and was materially unchanged after adjustment for all other baseline characteristics (HR, 1.05; 95% CI, 0.99-1.12). Cardiovascular mortality did not differ between groups (HR, 1.05; 95% CI, 0.94-1.16). Nonfatal outcomes were evaluated among 9,455 patients with fee-for-service Medicare: 4,542 (48.0%) in DPO and 4,913 (52.0%) in EPO facilities. During 10,457 and 10,363 person-years, 248 and 372 events were recorded, respectively, for strokes and MIs. We found no differences in adjusted stroke or MI rates or their composite with cardiovascular death (HR, 1.10; 95% CI, 0.96-1.25). Nonrandom treatment assignment, potential residual confounding.

    Hyperkalemia is common in patients with ESRD and may contribute to mortality. Dates have been reported to be high in potassium content. One of the concerns on hemodialysis (HD) is convincing patients to give up ingestion of dates as a part of their diet. To determine the effect of dates on serum potassium on patients, we studied 9 (M: F, 6:3, mean age 47.6) non diabetic patients on chronic hemodialysis, without evidence of hyperkalemia on monthly labs. Nearly all the patients had been on dialysis for an average of four years. The average monthly potassium was 4.6 mmol/L. The patients ingested 100 gm of dates (Rothana and Sukari) on two separate dialysis sessions. Serum potassium was measured at two and four hours post ingestion along with ECG monitoring. The patients underwent their regular dialysis as scheduled. The patients acted as their own controls and underwent the same protocol with 20meq of KCl on a separate session. The potassium levels did not change significantly over the four hours with either variety of dates or with potassium solution. Combining the two types of dates resulted in a trend towards higher potassium levels than with KCl, but it did not reach statistical significance. We conclude that in selected HD patients without hyperkalemia, ingestion of a few dates does not cause significant hyperkalemia and could be allowed on days of dialysis prior to their dialysis sessions.

    The use of liver allografts from elderly donors (≥70 years) has increased because of organ shortage and increased life expectancy. The aim of this study is to evaluate the current utilization of elderly donors in United States, recipient selection, and their posttransplant outcomes. A linkage between Scientific Registry of Transplant Recipients and University HealthSystem Consortium databases was performed. Between January 2007 and December 2011, 12,445 liver transplant (LT) recipients were identified and divided into 2 cohorts based on donor age: 70 years or older (n = 540) and younger than 60 years (n = 10,473). Elderly donors accounted for 4.3% of all donors used in the 5-year period. When compared to younger donors, elderly donors were more likely to be women, shared regionally or nationally, and used at higher volume centers. Elderly donor allografts were less likely to be used in recipients with model of end-stage liver disease score higher than 27 (13.2% vs. 23.0%, P < 0.001), hospitalized (16.8% vs. 21.7%, P = 0.03), or on hemodialysis at time of transplant (2.6% vs. 8.2%, P < 0.001). Both recipient groups had similar perioperative mortality, 30-day readmission rates, and short-term patient survival. In the multivariate analysis, including recipient, donor, center and regional factors, donor age 70 years or older was associated with slightly increased risk of graft loss (hazard ratio, 1.3; 95% confidence interval, 1.08-1.56; P = 0.005). The current trend toward the use of elderly donors in liver transplant recipients with low model of end-stage liver disease scores (<27), without hepatitis C, not hospitalized and not on dialysis, is associated with acceptable perioperative outcomes, patient survival, and slightly worse graft survival.

    Age can affect the clinical features and severity of infectious disorders, such as scrub typhus. We performed this study to examine differences between elderly and non-elderly scrub typhus patients, and to identify risk factors predictive of disease outcomes. This retrospective study included patients admitted to a tertiary hospital with scrub typhus between 2001 and 2011. A total of 615 patients were enrolled in this study, 328 of which were >65 years of age. Of the elderly patients, 46.0% (151/328) experienced at least one complication compared to only 23.0% (66/287) in younger patients. A linear trend was observed between age and complication rates (p=0.002). The most common complication in elderly patients was acute kidney injury (75, 22.9%). Treatment failure was reported in 10 elderly patients (3.0%) compared to one non-elderly patient (0.3%). Mental confusion and dyspnea of clinical manifestations at admission were common in elderly patients. Frequency of fever, rash, and eschar were similar in both groups. The following four factors were significantly associated with severe scrub typhus in elderly patients: (1) white blood cell (WBC) counts>10,000/mm(3) (OR=2.569, CI=1.298-5.086), (2) MDRD GFR<60mL/min (OR=3.525, CI=1.864-6.667), (3) albumin≤3.0g/dL (OR=4.976, CI=2.664-9.294), and (4) acute physiology and chronic health evaluation II (APACHE II) score>10 points (OR=3.304, CI=1.793-60.87). Complications and mortality were more common in elderly patients, often associated with delays in diagnosis and treatment. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Depression is common in patients on hemodialysis, but data on the benefits and risks of antidepressants in this setting are limited. We conducted a multicenter, randomized, double-blind, placebo-controlled trial of sertraline over 6 months in patients on hemodialysis with depression to determine study feasibility, safety, and effectiveness. Patients on hemodialysis at five United Kingdom renal centers completed the Beck Depression Inventory II. Those scoring ≥16 and not already on treatment for depression were invited to undergo diagnostic interview to confirm major depressive disorder. Eligible patients with major depressive disorder were randomized to receive the study medication-either sertraline or placebo. Outcomes included recruitment and dropout rates, change in the Montgomery-Asberg Depression Rating Scale and Beck Depression Inventory II, and qualitative information to guide design of a large-scale trial. In total, 709 patients were screened and enrolled between April of 2013 and October of 2014; 231 (32.6%) had Beck Depression Inventory II scores ≥16, and 68 (29%) of these were already receiving treatment for depression. Sixty-three underwent diagnostic interview, 37 were diagnosed with major depressive disorder, and 30 were randomized; 21 completed the trial: eight of 15 on sertraline and 13 of 15 on placebo (P=0.05). Dropouts due to adverse and serious adverse events were greater in the sertraline group. All occurred in the first 3 months. Over 6 months, depression scores improved in both groups. Beck Depression Inventory II score fell from 29.1±8.4 to 17.3±12.4 (P<0.001), and Montgomery-Asberg Depression Rating Scale score fell from 24.5±4.1 to 10.3±5.8 (P<0.001). There were no differences between sertraline and placebo groups. Although small, this is the largest randomized trial to date of antidepressant medication in patients on hemodialysis. Our results highlight recruitment issues. No benefit was observed, but trial size and the substantial

    Purpose Metabolic syndrome is a cluster of biochemical abnormalities including cardiovascular and diabetes risk factors. The development of diabetes mellitus after renal transplant represents a major posttransplant complication that may adversely affect graft/patient survival. The aim of this study was to assess the role of metabolic syndrome in patients on hemodialysis as a risk factor for the incidence of new-onset diabetes mellitus after renal transplant. Patients and methods This was a prospective observational epidemiologic study carried out in adult nondiabetic patients undergoing chronic hemodialysis and on the renal transplant waiting list between November 2008 and April 2009. Patients were followed up from Visit 1 (baseline) to 6 months after the renal transplant. The analysis of the role of metabolic syndrome in hemodialysis patients as a risk factor for the incidence of new-onset diabetes mellitus after renal transplant included the estimation of relative risk and its 95% confidence interval (CI). Results A total of 383 evaluable patients were entered into the study (mean age, 52.7 years; male, 57.7%; Caucasian, 90.1%). The prevalence of metabolic syndrome on hemodialysis was 30.4% (95% CI, 25.8%–35.4%). Hypertension was the most prevalent criterion for metabolic syndrome (65.0%), followed by low levels of high-density lipoprotein cholesterol (52.7%), abdominal obesity (36.2%), hypertriglyceridemia (32.4%), and impaired glucose (8.9%). After the renal transplant, the prevalence of metabolic syndrome was still 25.8%. During the posttransplant period, the incidence of new-onset diabetes mellitus reached 13.0% (95% CI, 7.8%–20.6%) and patients with pretransplant metabolic syndrome were 2.6 times (95% CI, 1.043–6.608) more likely to develop new-onset diabetes mellitus after the renal transplant than those without metabolic syndrome. Conclusion The presence of metabolic syndrome in patients undergoing hemodialysis represents an independent risk factor
