    The elderly, (age ≥ 65 years) hemodialysis (HD) patient population is growing rapidly across the world. The risk of accidental falls is very high in this patient population due to multiple factors which include aging, underlying renal disease and adverse events associated with HD treatments. Falls, the most common cause of fatal injury among elderly, not only increase morbidity and mortality, but also increase costs to the health system. Prediction of falls and interventions to prevent or minimize fall risk and associated complications will be a major step in helping these patients as well as decreasing financial and social burdens. Thus, it is vital to learn how to approach this important problem. In this review, we will summarize the epidemiology, risk factors, pathophysiology and complications of falls in elderly HD patients. We will also focus on available methods to assess and predict the patients at higher risk of falling and will provide recommendations for interventions to reduce the occurrence of falls in this population.

    The purpose of this experimental field pilot study was to determine whether the application of psychosocial education sessions had an effect on the adaptation level of elderly hemodialysis patients. A pretest, posttest control group design with two randomly selected groups was used. Ten patients, 4 males and 6 females, age 65 years and older, were randomly selected and stratified according to gender, with 2 males and 3 females assigned to either an experimental or a control group. The Psychosocial Adjustment to Illness Scale, Self-Report (PAIS-SR) was administered as a pretest 1 week prior to implementation of the intervention with the experimental group. It was again given as a posttest 30 days after completion of the intervention. The intervention, 7 psychosocial educational sessions with 7 audiotapes and a companion text module, provided information. These sessions were conducted with the experimental group, 2 days a week, during the subjects' hemodialysis treatments, taking approximately 20 minutes each, over a period of 4 1/2 weeks. Data were analyzed utilizing t-tests and descriptive statistics. No significant differences were found between the scores of the pretest and posttest when comparing the two groups. However, a significant value of 0.035 (p < 0.05) was evident in one domain of the PAIS-SR, the domestic environment, when comparing the scores of the pretest and posttest of the experimental group. The application of psychosocial education sessions did not have a significant effect on the adaptation level of elderly hemodialysis patients.

    [Purpose] The aim of this study was to ascertain the optimum strategy for implementing a physical activity intervention in patients on hemodialysis by investigating the physical characteristics of elderly patients on hemodialysis, and their attitude to physical activity and level of daily activity. [Subjects] The Subject were 10 elderly patients on hemodialysis. [Methods] They wore a physical activity monitor for 1 week. Data obtained were analyzed for hemodialysis and non- hemodialysis days, and two-way analysis of variance was used to compare the number of steps and activity levels. A questionnaire was administered to investigate the stage of psychological preparedness for exercise and attitudes toward/awareness of exercise. [Results] There was no significant difference in the number of steps or exercise levels on hemodialysis and non- hemodialysis days. However, on both types of days, subjects spent long periods not engaged in any activity. Most of their activity was either inactivity or sedentary behavior. [Conclusion] Patients on hemodialysis with low physical activity levels are considered to have poor physical function and exercise tolerance. To maintain and improve the physical function of patients on hemodialysis, it will be necessary to reduce their time spent in inactive, and comprehensive care that covers psychosocial aspects should be provided to promote the proactive improvement of physical activity and their attitudes to exercise.

    The outcomes of peritoneal dialysis (PD) in elderly patients have not been thoroughly investigated. We aimed to investigate the clinical outcomes and risk factors associated with PD in elderly patients. We conducted a prospective observational nationwide adult end-stage renal disease (ESRD) cohort study in Korea from August 2008 to March 2013. Among incident patients (n = 830), patient and technical survival rate, quality of life, and Beck’s Depression Inventory (BDI) scores of elderly PD patients (≥65 years, n = 95) were compared with those of PD patients aged ≤49 years (n = 205) and 50~64 years (n = 192); and elderly hemodialysis (HD) patients (n = 315). The patient death and technical failure were analyzed by cumulative incidence function. Competing risk regressions were used to assess the risk factors for survival. The patient survival rate of elderly PD patients was inferior to that of younger PD patients (P<0.001). However, the technical survival rate was similar (P = 0.097). Compared with elderly HD patients, the patient survival rate did not differ according to dialysis modality (P = 0.987). Elderly PD patients showed significant improvement in the BDI scores, as compared with the PD patients aged ≤49 years (P = 0.003). Low albumin, diabetes and low residual renal function were significant risk factors for the PD patient survival; and peritonitis was a significant risk factor for technical survival. Furthermore, low albumin and hospitalization were significant risk factors of patient survival among the elderly. The overall outcomes were similar between elderly PD and HD patients. PD showed the benefit in BDI and quality of life in the elderly. Additionally, the technical survival rate of elderly PD patients was similar to that of younger PD patients. Taken together, PD may be a comparable modality for elderly ESRD patients. PMID:26121574

    We analyzed retrospectively the outcome of 169 patients in chronic hemodialysis (CHD), divided into four groups: 1) 24 patients with diabetic nephropathy (age 53.7 +/- 11 years); 2) 19 with polycystic kidney disease (age 55.3 +/- 9 years) 3) 43 patients older than 60 when starting chronic hemodialysis with etiologies different from diabetes and polycystic kidney disease (age 69.2 +/- 5.8 years) and 4) 83 patients younger than 60 with diverse etiologies (age 42.8 +/- 12.4 years). In groups 1, 2 and 3 serum creatinine, arterial hypertension at the beginning, morbility, mortality and its causes were registered. In group 1, the prevalence of severe diabetic retinopathy and cardiovascular disease at the beginning were also analyzed. In all groups survival was determined. Of the diabetics, 92% presented severe diabetic retinopathy and 88% cardiovascular disease. The prevalence of hypertension was 100, 74 and 67% in groups 1, 2 and 3, respectively (p = 0.13). Twelve diabetics died before the first year of treatment; there was no difference in creatinine, age, cardiovascular disease, severe retinopathy and hypertension with those who lived more than one year. The percentage of time in risk hospitalized and the days/patients/year hospitalized were significantly different between group 1 and 3 and group 2 (p < 0.001). Patients were hospitalized for similar causes in groups 1 and 3: the initiation of CHD, cardiovascular and neurological diseases. The main causes of death in groups 1 and 3 were: cardiovascular disease and sudden death at home. Survival was better in group 2 compared with group 1 (p = 0.0014) but was similar between groups 1 and 3 (p = 0.21) even though there was a difference of 15 years between them. The Cox's proportional hazard model identified as risk factors diabetes, age, year of starting chronic hemodialysis and hospitalization episodes, adjusted for covariates. The outcome of diabetic patients in chronic hemodialysis showed high morbidity and mortality

    Hemodialysis affects not only physical but psychological and social aspects, with repercussions on personal and family life. Considering the increase in the elderly population in Brazil, this study aims to evaluate the quality of life of elderly patients with chronic renal failure undergoing hemodialysis. This is a quantitative, descriptive exploratory study with elderly patients held in a facility specializing in hemodialysis in Guarapuava, Paraná, Brazil. The data were collected between May and June 2010, through a structured instrument and were submitted to the statistical software Statistica 7.1. Analyzing the domains of the questionnaire the highest score refers to the social domain (70.42) and the lowest, to the physical domain (49.37). Thus, the quality of life of these elderly had to be low, with variations according to the analyzed field. Researches aimed at assessing quality of life are relevant and instrumentalize the daily practice of care.

    Background Phosphate binders are an important therapeutic option for managing hyperphosphatemia in hemodialysis patients. Whether sevelamer confers a survival advantage over calcium acetate is unclear. Study Design Observational cohort study using US Renal Data System (USRDS) data linked to Medicare Part D prescription drug data. Setting & Participants Medicare-enrolled, elderly, incident hemodialysis patients initiating calcium acetate or sevelamer between July 1, 2006, and March 31, 2011. Predictor Prescription for sevelamer (hydrochloride or carbonate) or calcium acetate. Outcomes & measurements All-cause and cardiovascular-related mortality, hospital admissions and hospital days assessed from Medicare Parts A, B, and D claims and other USRDS data. Results The sevelamer and calcium acetate groups included 16,916 and 18,335 patients, respectively. After multivariable adjustment, all-cause (21.9 versus 21.8 deaths per 100 patient-years; adjusted HR, 0.97; 95% CI, 0.94-1.03) and cardiovascular (8.7 versus 8.6 deaths per 100 patient-years; HR, 0.99; 95% CI, 0.93-1.04) mortality did not differ significantly between the sevelamer group and calcium acetate group (referent). Mortality results in propensity-score matched cohorts showed a significantly lower risk of death in sevelamer than in calcium acetate patients (HR, 0.94; 95% CI, 0.91-0.98). Mortality results from additional analyses including only patients with low-income subsidy status were consistent with results from analyses including patients with and without low-income subsidy status. There were no significant differences between the sevelamer and calcium acetate groups for all-cause and cardiovascular-related first hospitalization, multiple hospitalizations, and hospital days. Limitations Results may not be applicable to younger patients; information about laboratory data and over-the-counter calcium-containing binders was lacking.

    Although peritoneal dialysis (PD) has been advocated as a suitable substitution therapy in patients with failure of hemodialysis (HD) blood access, documentation of the performance of PD in such patients is limited. Here, we present an elderly patient with total failure of HD blood access who has had a remarkably successful course on PD. A 78-year-old man with several comorbidities started continuous ambulatory PD after a 3.5-year course of HD complicated by repeated vascular access infections and clotting episodes. These access complications resulted in 8 hospitalizations and led to inability to ambulate following a right femoral shaft fracture sustained in a fall secondary to confusion during an episode of access sepsis, and to superior vena cava (SVC) syndrome following SVC thrombosis after internal jugular catheter insertion. Over approximately 3 years, PD has been very successful in this patient, with 2 early routine episodes of peritonitis and 1 early episode of exit-site infection, control of hematologic and biochemical values, no hospitalizations in the 2.5 years before the time of writing, and good quality of life. A dedicated spouse performing the PD tasks has been a major factor in the success of PD in this patient. Peritoneal dialysis can be successful as a renal replacement procedure in incapacitated elderly patients with failure of HD blood access. In these cases, the success of PD is enhanced by dedicated family members taking on PD tasks that the patient cannot perform.

    Pleural effusion is a ubiquitous complication in hemodialysis (HD) patients. Common etiologies of pleural effusion in this patient group are heart failure, volume overload, parapneumonic effusion, tuberculotic pleuritis, and uremic pleuritis. Although thoracentesis is a useful diagnostic method of pleural effusion, empirical reduction of the dry weight is often attempted without thoracentesis because pleural effusion is commonly caused by volume overload and responds to the dry-weight reduction. However, this empiricism has a risk of overlooking or delaying the diagnosis of potentially fatal etiologies that need specific treatments. We report an 86-year-old human immunodeficiency virus (HIV)-negative male on HD with primary effusion lymphoma (PEL), a large-cell non-Hodgkin lymphoma presenting with characteristic lymphomatous effusions in the absence of solid tumor masses, which is in association with human herpes virus 8 (HHV8) infection in immunocompromised individuals. The patient presented with left-sided pleural effusion. This is the first case report of PEL developing in a patient receiving HD. Thoracentesis and cytological analysis of the effusion was key to the diagnosis. We also review the literature regarding pleural effusion in HD patients. Further, we examine Kaposi's sarcoma herpes virus/HHV8-negative effusion-based lymphoma, a newly proposed distinct lymphoma that clinically and cytomorphologically resembles PEL, because it can be cured without chemotherapy. This report may arouse clinicians' attention regarding the importance of evaluation for pleural effusion in HD patients, especially when the effusion or symptoms associated with pleural effusion are refractory to volume control.

    Hemodialysis is the predominant replacement therapy in the 70 year-old French population (18% in peritoneal dialysis, 72% in hemodialysis from the REIN registry). Managing older patients reaching the end stage renal disease poses many ethical questions, since outcomes balanced regarding survival and quality of life. The aim of this study was to compare the survival of patients aged over 70 years according to the ESRD treatment choice: conservative treatment without dialysis (CT), hemodialysis (HD) and peritoneal dialysis (PD). We included all patients over 70 years reaching stade IV CKD integrated in a predialysis information program between 01/01/2005 and 31/12/2010. We compared their survival from the start of their program, in function of their treatment choice: HD, PD or CT. On this period, 148 patients were included, we excluded from analysis 17 patients who had a contraindication to PD, 26 patients who did not make a choice because their kidney function was stabilized, 4 patients lost to follow-up and 12 patients who died before the treatment choice. The average age was 79±6 years, 40% of patients were women, and the mean eGFR was 16±9 mL/min/1.73 m(2) at the entry in the program. Among the 89 patients, 21 choose CT (24%), 68 accepted dialysis (76%), including 48 HD (71%) and 20 PD (29%). No significant eGFR difference at the inclusion time between the groups. The time initiation of dialysis was significantly shorter in the PD group (146 days vs 442 in the HD group; P=0.004). Survival between the groups of patients who accepted or refused dialysis was not statistically different (749 days or 2 years in the HD + PD group vs 562 days, or 1 year and 6 months in the CT group; P=0.95) and between the HD group (760 days or 2 years and 2 months) and the PD group (343 days or 11 months; P=0.32). As measured from the time they entered in the predialysis program, the survival of older patients over 70 years does not seem to depend on

    OBJECTIVE: to assess the quality of life of chronic kidney patients undergoing hemodialysis, using the WHOQOL-bref and WHOQOL-SRPB. METHOD: a descriptive and cross-sectional study was undertaken at a kidney replacement therapy service in the interior of the state of SP. The 110subjects who complied with the inclusion criteria answered the Subject Characterization Instrument, the WHOQOL-bref and WHOQOL-SRPB. RESULTS: most of the respondents were male (67.27%), with a mean age of 55.65 years, Catholic (55.45%), with unfinished primary education (33.64%) and without formal occupation (79.08%). The WHOQOL-bref domains with the highest and lowest mean score were, respectively, "psychological" (µ=74.20) and "physical" (µ=61.14). The WHOQOL-SRPB domains with the highest and lowest mean score were, respectively, "completeness and integration" (µ=4.00) and "faith" (µ=4.40). CONCLUSIONS: the respondents showed high quality of life scores, specifically in the dimensions related to spirituality, religion and personal beliefs. Losses were evidenced in the physical domain of quality of life, possibly due to the changes resulting from the chronic kidney disease and hemodialysis treatment. PMID:25591085

    Receipt of pre-end-stage renal disease (ESRD) clinical care can improve outcomes for patients treated with maintenance hemodialysis (MHD). The study addressed age-related variations in receipt of a composite of recommended care to include nephrologist and dietician care and use of arterio-venous fistula at first outpatient MHD. Less than 2% of patients treated with MHD received all three forms of pre-ESRD care, and 63.3% received none of the three elements of care. The mean number of pre-ESRD care elements received by the oldest group (≥80 years) did not differ from the youngest group (<55 years), but was less than the 55-66 and 67-79 years groups; adjusted ratios of 0.93 (0.92-0.94; p<0.001) and 0.94 (0.92-0.95; p<0.001), respectively. A major effort is needed to ensure comprehensive pre-ESRD care for all patients with advanced CKD, especially for the youngest and oldest patient groups, who were less likely to receive recommended pre-ESRD care.

    Poor sleep among the general population is understudied, unrecognized, and often not assessed This is especially true for patients receiving hemodialysis. This study used a case study design to examine the impact of hemodialysis treatments on the sleep of two patients as measured by actigraphy and self-reported sleep logs. Patient 1 experienced an average sleep efficiency of 82.3% on non-hemodialysis days compared to 75.0% on dialysis days, which resulted in a 7.3 percentage point change and 9.7% better sleep efficiency on non-hemodialysis days. Patient 2 reported sleep efficiency 76.6% on non-hemodialysis days compared to 70.5% dialysis on days, resulting in a 6.1 percentage point change and 8.7% better sleep efficiency on non-hemodialysis days. Actigraphy sleep patterns provided an initial move toward best practice for sleep evaluation in this population.

    Protein energy wasting (PEW) is highly prevalent in patients undergoing maintenance hemodialysis (MHD) patients. Importantly, there is a robust association between the extent of PEW and the risk of hospitalization and death in these patients, regardless of the nutritional marker used. The multiple etiologies of PEW in advanced kidney disease are still being elucidated. Apart from the multiple mechanisms that might lead to PEW, it appears that the common pathway for all the derangements is related to exaggerated protein degradation along with decreased protein synthesis. The hemodialysis procedure per se is an important contributor to this process. Metabolic and hormonal derangements such as acidosis, inflammation and resistance to anabolic properties of insulin resistance and growth hormone are all implicated for the development of PEW in MHD patients. Appropriate management of MHD patients at risk for PEW requires a comprehensive combination of strategies to diminish protein and energy depletion, and to institute therapies that will avoid further losses. The mainstay of nutritional treatment in MHD patients is provision of an adequate amount of protein and energy, using oral supplementation as needed. Intradialytic parenteral nutrition should be attempted in patients who cannot use the gastrointestinal tract efficiently. Other anabolic strategies such as exercise, anabolic hormones, anti-inflammatory therapies and appetite stimulants can be considered as complementary therapies in suitable patients. PMID:23439378

Although the pathophysiology of this syndrome remains unknown yet, an investigation of the parameters pertinent to it may help to develop the related medical knowledge and to improve the therapeutic-care interventions in this regard. Objectives: The correlation between the RLSs on individual, clinical, and laboratory indices in patients undergoing hemodialysis. Patients and Methods: This descriptive-analytic study was conducted on 104 hemodialysis patients. Diagnosis of RLS was made using the International RLS Standard Questionnaire. The data on individual, clinical, and laboratory indices were obtained from patients’ recorded files and interviews. Results: Based on our findings, 28.8% of the patients undergoing hemodialysis were affected with mild RLS, 41.7% with moderate RLS, and 29.5% with severe RLS. There was a statistically significant correlation between affliction with RLS on the one hand, and age and gender, on the other (P < 0.05). However, there was no significant correlation between RLS and education level, occupation, length of hemodialysis, fasting blood sugar (FBS), hepatitis B and C, serum blood urea nitrogen (BUN), creatinine (Cr), iron, hemoglobin (Hb) level and also KT/Vor URR (P < 0.05). Conclusion: Regarding the high prevalence of RLS among the hemodialysis patients, there is the necessity for taking more care of these patients to reduce the somatic complications of the RLS especially among the elderly and female patients and to control the blood sugar of these patients at the normal level.

    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.

    Despite reduction of hepatitis C prevalence after recognition of the virus and testing of blood products, hemodialysis (HD) patients still comprise a high risk group. The natural history of hepatitis C virus (HCV) infection in dialysis is not fully understood while the clinical outcome differs from that of the general population. HD patients show a milder liver disease with lower aminotransferase and viral levels depicted by milder histological features on liver biopsy. Furthermore, the “silent” clinical course is consistent with a slower disease progression and a lower frequency of cirrhosis and hepatocellular carcinoma. Potential explanations for the “beneficial” impact of uremia and hemodialysis on chronic HCV infection are impaired immunosurveillance leading to a less aggressive host response to the virus and intradialytic release of “hepatoprotective” cytokines such as interferon (IFN)-α and hepatocyte growth factor. However, chronic hepatitis C is associated with a higher liver disease related cardiovascular and all-cause mortality of HD patients. Therapy is indicated in selected patients groups including younger patients with low comorbidity burden and especially renal transplant candidates, preferably after performance of a liver biopsy. According to current recommendations, choice of treatment is IFN or pegylated interferon with a reported sustained viral response at 30%-40% and a withdrawal rate ranging from 17% to 30%. New data regarding combination therapy with low doses of ribavirin which provide higher standard variable rates and good safety results, offer another therapeutic option. The new protease inhibitors may be the future for HCV infected HD patients, though data are still lacking. PMID:25848478

    Background Research pertaining to the nutritional intake of hemodialysis patients is limited. Purpose Describe the nutritional quality of foods consumed by hemodialysis patients and variation by day of the week. Methods Dietary recalls were obtained from 22 hemodialysis patients and analyzed using the Nutrition Data System for Research. Results Few statistically significant differences were found by day of the week, but several dietary deficits were noted. Conclusion The data suggest poor intake of calories, protein, and several vitamins and minerals, as well as excess sodium consumption, but little variation by day of the week. Additional research is needed. PMID:25104876

    The prevalence of sleep disorders is higher in patients with kidney failure than the general population. We studied the prevalence of sleep disorders in 88 (mean age; 41.59 +/- 16.3 years) chronic hemodialysis (HD) patients at the Urology and Nephrology Center, Mansoura University, Egypt over 4-month period. The investigated sleep disorders included insomnia, restless leg syndrome (RLS), obstructive sleep apnea syndrome (OSAS), excessive daytime sleepiness (EDS), narcolepsy and sleep walking, and we used a questionnaire in accordance with those of the International Restless Legs Syndrome Study Group, the Berlin questionnaire, Italian version of Epworth Sleepiness Scale, International Classification of Sleep Disorders, and the specific questions of Hatoum's sleep questionnaire. The prevalence of sleep disorders was 79.5% in our patients, and the most common sleep abnormality was insomnia (65.9%), followed by RLS (42%), OSAS (31.8%), snoring (27.3%), EDS (27.3%), narcolepsy (15.9%), and sleep walking (3.4%). Insomnia correlated with anemia (r=0.31, P= 0.003), anxiety (r=0.279, P= 0.042), depression (r=0.298, P= 0.24) and RLS (r=0.327, P= 0.002). Also, RLS correlated with hypoalbuminemia (r=0.41, P= < 0.0001), anemia (r=0.301 and P= 0.046), hyperphosphatemia (r=0.343 and P= 0.001). EDS correlated with OSAS (r=0.5, P= < 0.0001), snoring (r=0.341, P= 0.001), and social worry (r=0.27, P= 0.011). Sleep disorders are quite common in the HD patients, especially those who are anemic and hypoalbuminemic. Assessment of sleep quality, preferably with polysomnography, is necessary to confirm our results. Interventional studies for management of sleep disorders in HD patients are warranted.

    Pyrophosphate (PPi) is a known inhibitor of hydroxyapatite formation and has been shown to inhibit medial vascular calcification in vitamin D-toxic rats. It was demonstrated recently that endogenous production of PPi prevents calcification of rat aorta that are cultured in high concentrations of calcium and phosphate. For determining whether PPi metabolism is altered in hemodialysis patients, plasma levels and dialytic clearance of PPi were measured in stable hemodialysis patients. Predialysis plasma [PPi] was 2.26 +/- 0.19 microM in 38 clinically stable hemodialysis patients compared with 3.26 +/- 0.17 in 36 normal subjects (P < 0.01). Approximately 30% of plasma PPi was protein bound, and this was not altered in dialysis patients. There was a weak inverse correlation with age in normal individuals but not in dialysis patients. Plasma [PPi] in dialysis patients was correlated with plasma [PO4(3-)] (r = 0.56) but not with [Ca2+], parathyroid hormone, or the dose of dialysis, and levels did not vary between interdialytic periods of 2 and 3 d. Plasma [PPi] decreased 32 +/- 5% after standard hemodialysis in 17 patients. In vitro clearance of PPi by a 2.1-m2 cellulose acetate dialyzer was 36%, and the mean PPi removal in five patients was 43 +/- 5 micromol, consistent with a similar in vivo clearance. Cleared PPi was greater than the plasma pool but less than the estimated extracellular fluid pool. Erythrocyte PPi content decreased 24 +/- 4%, indicating that intracellular PPi is removed as well. It is concluded that plasma [PPi] is reduced in hemodialysis patients and that PPi is cleared by dialysis. Plasma levels in some patients were below those that have previously been shown to prevent calcification of vessels in culture, suggesting that altered PPi metabolism could contribute to vascular calcification in hemodialysis patients.

    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.

    Hemodialysis catheter related infections (HCRI) are one of the major causes of increasing mortality, morbidity and cost of therapy in hemodialysis patients. Prevention of HCRI requires the identification of predisposing risk factors. To determine the frequency of HCRI risk factors, we studied 116 patients (54% male, mean age of 49.5+/-16 years) patients with HCRI between 2003-2004. Forty one percent of the patients were diabetic. There was a history of previous catheter placement and infection in 41% and 32% of patients, respectively. Pathogenic organisms isolated from blood cultures included Staphylococcus-aureus 42%, Coagulase-negative Staphylococci 20%, E. Coli 19%, Enterococci 7%, Streptococcus D 7%, Pseudomonas aeruginosa 4%, and Klebsiella 1%. Bacterial resistance to vancomycin and amikacin was present in 7% and 4% of the cases, respectively. Hemodialysis catheter related blood borne infections comprised 67% of the total blood-borne infections in our hospital. No significant statistical association was found between HCRI and age, gender, diabetes mellitus, serum albumin level <30 g/L, leukocyte count, erythrocyte sedimentation rate, anatomical location of catheter, mean duration of antibiotic therapy, mean catheter duration, frequency of hemodialysis sessions, pathogenic organisms, and history of previous catheter infection. We conclude that the prevalence of pathogenic organisms of HCRI were similar to previous studies. However, bacterial resistance to antibiotics was low. The mean duration of catheter usage was longer than previously reported. PMID:17237890

    With refinements and advances in hemodialysis techniques, survival for patients with end-stage renal disease has improved significantly. To our knowledge, however, no prospective trials have been performed in patients receiving hemodialysis who are also diagnosed with cancer and are candidates for chemotherapy. We describe a 73-year-old man who was diagnosed with high-grade neuroendocrine carcinoma, metastatic to the bone and lymph nodes, and was undergoing hemodialysis. Although cisplatin is more commonly used in the treatment of metastatic neuroendocrine cancers, it may not be the best option in patients who suffer from renal insufficiency. Carboplatin is a second-generation, nonnephrotoxic platinum analog that can be hemodialyzed, although no formal guidelines are available regarding the dosing for patients receiving hemodialysis. This case describes a patient who was treated with five cycles of combination carboplatin 115 mg/m(2) on day 1 and etoposide 50 mg/m(2) on day 1 and day 3 of a 28-day cycle. Dialysis was performed for 3.5 hours starting 90 minutes after completion of carboplatin on day 1. Pharmacokinetic assessments were performed at 1, 2, 4, and 12 hours after chemotherapy infusion on day 1 of cycle 1. Total carboplatin concentrations in plasma and platinum ultrafiltrate were measured. The plasma concentration of free platinum at the end of the infusion was 31,000 ng/ml, and the area under the plasma concentration-time curve was 2.9 minute·mg/ml. No significant carboplatin-related toxicities were reported. This case report indicates that carboplatin can be safely administered in patients receiving hemodialysis.

    To study the fate of amantadine hydrochloride in patients with renal failure, we gave 100 mg orally to 12 such patients immediately after hemodialysis. Plasma levels did not decrease between 24 and 44 hours after drug ingestion, suggesting an extremely poor total body clearance. Apparent volume of distribution was 5.1 +/- 0.2 (SEM) L/kg of body weight. Between 44 and 48 hours, as a result of 4 hours of hemodialysis, the mean plasma drug level decreased from 268 to 225 ng/mL (P less than 0.001). Dialyzer clearance was 67.0 +/- 3.9 mL of plasma per minute. The total quantity of drug removed by the dialysis treatment, however, was only 3.9 +/- 0.25 mg. The average half-life of amantadine in eight patients studied while receiving maintenance hemodialysis was 24.3 +/- 2.4 h of dialysis administered over approximately 13 days. Plasma half-life in six nonuremic control subjects was 12.2 +/- 1.6 h. Amantadine is poorly excreted in dialysis patients and has a large volume of distribution. The amount removed by a single dialysis is only a small fraction of the total body store. PMID:7396313

    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

    Background: Serum protein profiling patterns can reflect the pathological state of a patient and therefore may be useful for clinical diagnostics. Here, we present results from a pilot study of proteomic expression patterns in hemodialysis patients designed to evaluate the range of serum proteomic alterations in this population. Methods: Surface-Enhanced Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (SELDI-TOFMS) was used to analyze serum obtained from patients on periodic hemodialysis treatment and healthy controls. Serum samples from patients and controls were first fractionated into six eluants on a strong anion exchange column, followed by application to four array chemistries representing cation exchange, anion exchange, metal affinity and hydrophobic surfaces. A total of 144 SELDI-TOF-MS spectra were obtained from each serum sample. Results: The overall profiles of the patient and control samples were consistent and reproducible. However, 30 well-defined protein differences were observed; 15 proteins were elevated and 15 were decreased in patients compared to controls. Serum from one patient exhibited novel protein peaks suggesting possible additional changes due to a secondary disease process. Conclusion: SELDI-TOF-MS demonstrated dramatic serum protein profile differences between patients and controls. Similarity in protein profiles among dialysis patients suggests that patient physiological responses to end-stage renal disease and/or dialysis therapy have a major effect on serum protein profiles.

    The risk of premature and progressive occlusive vascular disease is high in chronic uremic patients, and it accounts for more than 40% of the mortality in dialysis patients. End stage renal failure (ESRF) patients exhibit elevated plasma homocystein levels, about four fold as much as those in the controls, and it is now considered as a causative factor for increased risk of cardiovascular death among these patients. The aim of this study was to evaluate the relationship of total plasma homocysteine level and echocardiographic abnormalities as a surrogate of cardiac disease outcome in hemodialysis patients. 123 adult patients on maintenance hemodialysis and having echocardiography done during January till November 2006 were enrolled in this cross-sectional study. Plasma homocysteine level was directly related to the presence of aortic regurgitation r= 0.27 P= 0.009. There were negative correlations between ejection fraction (EF), left ventricular systolic dimension (LV.S) (r= - 0.71, P= 0.0001), left ventricular diastolic dimension (LV.D) (r= -0.23 p= 0.01) and age (r= - 0.021 P= 0.02). In conclusion we did not find the paradoxical reverse epidemiology in our patients and plasma total homocysteine level was in direct correlation with cardiac risk factors such as left ventricular mass index and aortic regurgitation.

    Increased arterial stiffness in hemodialysis patients is a strong predictor of cardiovascular morbidity and mortality. Pulse wave velocity (PWV) and augmentation index (AIx), which are markers of arterial stiffness, were used to determine the severity of vascular damage noninvasively. This study aimed to investigate the effects of solute volume removal and hemodynamic changes on PWV and AIx of a single hemodialysis session. Thirty hemodialysis patients were enrolled in the study. Before initiation of hemodialysis, every 15 minutes during hemodialysis, and 30 minutes after the completion of the session, measurements of PWV and AIx@75 (normalized with heart rate 75 bpm) were obtained from each patient. Body composition was analyzed by bioimpedance spectroscopy device before and 30 minutes after completion of the hemodialysis session. During the hemodialysis, no significant change was observed in AIx@75. However, PWV decreased steadily during the session reaching statistically significant level at 135th minute (P = 0.026), with a maximal drop at 210th minute (P < 0.001). At 210th minute, decrease in PWV correlated positively with the decrease in central systolic blood pressure, central diastolic blood pressure, central pulse pressure, augmentation pressure, and AIx@75. Multiple regression analysis showed that decrease in PWV at 210th minute was associated with decrease in central systolic blood pressure and central pulse pressure. Ultrafiltration during hemodialysis had no significant effect on PWV and AIx@75. Delta urea correlated positively with delta PWV at 240th minute. A significant decrease in PWV was observed during hemodialysis and correlated with urea reduction; however, we were unable to document any effect of volume removal on arterial stiffness.

    Recent studies have suggested improvements in quality of life (QOL) in patients on quotidian dialysis compared with conventional hemodialysis. Few studies have focused on the burden and QOL in caregivers of patients with end-stage renal disease (ESRD) on nocturnal home hemodialysis (NHD). We aim to assess the caregivers' burden, QOL, and depressive symptoms and to compare these parameters with their patients' counterparts. Cross-sectional surveys were sent to 61 prevalent NHD patients and their caregivers. Surveys assessed demographics, general self-perceived health using the 12-Item Short Form Health Survey (SF-12) and the presence of depression using the Beck Depression Inventory. Subjective burden on caregivers was assessed by the Caregiver Burden scale and was compared with perceived burden by the patients. Thirty-six patients and 31 caregivers completed the survey. The majority of caregivers were female (66%), spouse (81%) with no comorbid illness (72%). Their mean age was 51 ± 11 years. Patients were mostly male (64%) with a median ESRD vintage of 60 months (interquartile range [IQR], 18-136 months) and a mean age of 52 ± 10 years. Compared to caregivers, patients had lower perceived physical health score but had similar mental health score. Depression criteria were present in 47% of patients and 25% of caregivers. Total global burden perceived by either caregivers or patients is relatively low. Although there is a relatively low global burden perceived by caregivers and patients undergoing NHD, a significant proportion of both groups fulfilled criteria for depression. Further innovative approaches are needed to support caregivers and patients performing NHD to reduce the intrusion of caring for a chronic illness and the risk of developing depression.

    Introduction: Nowadays, the chronic diseases are known to be associated with lifestyle risk factors. Hemodialysis patients encounter considerable amount of physical, mental and social pressure. Lifestyle is important because it affects quality of life and has important role in prevention. This study aimed to compare the lifestyle of hemodialysis patients and outpatients in health clinics of Tabriz. Methods: This was a case-control study on 155 hemodialysis patients and 155 outpatients referring to five dialysis centers and clinics, who met the inclusion criteria. Demographic data and some questions about lifestyle in nutrition, stress, physical activity and smoking were asked. Results: The history of hypertension among hemodialysis patients was 34.6% greater than outpatients. High daily salt consumption (more than two tablespoons a day) was 40.5% higher among hemodialysis patients than outpatients. In terms of saturated oil intake, it was 30.8%higher among hemodialysis patients. Problem in communicating with family members was 69.8% higher in hemodialysis patients. In terms of physical activity, 46.4% of outpatients had higher physical activity like walking. Conclusion: Lifestyle in different dimensions was associated with chronic kidney disease (CKD); therefore, the officials of health system are recommended to develop a program to combat chronic diseases and integrate it with providing the first-level health services. It seems that public education can have a major role in life-style modification and in chronic kidney diseases prevention. PMID:25276683

    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.

    The aim of our study was to evaluate the frequency of fibromyalgia syndrome (FMS) in hemodialysis (HD) patients and to assess whether this syndrome is associated with gender, age, duration of HD, or various laboratory parameters. This study was composed of 221 chronic HD patients (99 females and 122 males), and we recorded each participant's age, gender, causes of kidney failure, HD duration, education level, and symptoms related to FMS, which was diagnosed according to the 2010 American College of Rheumatology criteria. We documented the laboratory parameters for all patients. In addition, patients with FMS filled out the Fibromyalgia Impact Questionnaire. Twenty-two patients met the diagnostic criteria for FMS (9%), and there were no statistically significant differences related to age, gender, or HD duration between FMS and non-FMS groups (P > 0.05). In addition, the education levels were lower in patients diagnosed with FMS (P < 0.05), and there were statistically significant differences related to sleep disturbance, fatigue, and cognitive symptoms between the two groups (P < 0.05) as well. However, their laboratory parameters were similar (P > 0.05). There was a higher prevalence of FMS in HD patients than in the general population. Sleep disturbances, fatigue, education level, and cognitive symptoms were associated with FMS, but there was no correlation between the laboratory parameters and this condition.

    Malnutrition is a predictor of increased mortality in chronic hemodialysis (HD) patients. Various factors may contribute to malnutrition in these patients including energy and protein intake, inflammation, and comorbidity. To determine the importance of these factors in malnutrition of chronic HD patients, we studied 112 chronic HD patients in two centers was evaluated with the Dialysis Malnutrition Score (DMS) and anthropometric and biochemical indices. Seventy six (67.8%) patients were classified as malnourished. According to DMS score, poor protein intake (r= -0.34, P< 0.01), comorbidities (r= -0.24, P< 0.05), poor energy intake (r= - 0.18, P< 0.005), and inflammation (r= -0.16, P< 0.05) were significant predictors of malnutrition in descending order of importance. Multiple regression analysis showed that only poor protein intake was the explanatory variable of anthropometric measurements decline including body mass index, triceps skin fold thick-ness, mid arm circumference, mid arm muscle circumference, fat free mass, fat mass, albumin, creatinine and transferrine. None of the mentioned factors predicted the decrease of biochemical markers. We conclude that the frequency of malnutrition is high in our population and poor protein intake is the primary contributing factor for this condition. Therefore, providing enough protein may be a simple and effective way in preventing malnutrition in these patients.

    Nickel was analyzed by electrothermal atomic absorption spectrophotometry in serum specimens from 22 healthy hospital workers and 30 patients with end-stage renal disease treated by extracorporeal hemodialysis, who resided in Sudbury, Ontario, Canada, a city with extensive nickel mines and smelters. Samples of tap water from Sudbury contained 109 +/- 46 micrograms Ni per L (P less than 0.01 vs 0.4 +/- 0.2 micrograms Ni per L in corresponding water samples from Hartford, Connecticut). Serum nickel concentrations averaged 0.6 +/- 0.3 micrograms Ni per L in Sudbury hospital workers (P less than 0.05 vs 0.2 +/- 0.2 micrograms Ni per L in corresponding serums from 43 healthy hospital workers in Hartford). In serums collected post-treatment from Sudbury hemodialysis patients, nickel concentrations averaged 8.5 +/- 2.8 micrograms Ni per L, (i.e., 14-times the corresponding mean in Sudbury hospital workers, P less than 0.01), but were not significantly higher than the nickel concentrations in serums from 42 Hartford hemodialysis patients (7.2 +/- 2.2 micrograms Ni per L). This study confirms the presence of hypernickelemia in hemodialysis patients, but does not suggest that hemodialysis patients have significantly increased risk of nickel toxicity in Sudbury, compared to Hartford, despite the high nickel concentrations in Sudbury tap water. This favorable outcome attests to the efficient deionization of water used to prepare hemodialysis solutions in Sudbury.

    Background The prevalence of pulmonary hypertension is unusually high in Taiwanese patients with end-stage renal disease. Thrombosis of hemodialysis grafts is common and pulmonary embolism has been reported after endovascular thrombectomy. The aim of this study was to evaluate the relationship between pulmonary hypertension and endovascular thrombectomy of hemodialysis grafts. Methods One hundred and ten patients on hemodialysis via arteriovenous grafts were enrolled in our study. The mean pulmonary artery pressure (PAP) was measured by right heart catheterization. Clinical information was collected by review of medical records. Comorbid cardiopulmonary disease was evaluated by echocardiography and chest X-ray. The history of patient vascular access thrombosis was reviewed from database, hemodialysis records, and interviews with staff at hemodialysis centers. Results Fifty-two participants (47%) had pulmonary hypertension diagnosed by right heart catheterization. There was no difference in the number of thrombectomy procedures between patients with and without pulmonary hypertension. Based on multivariate analysis, the number of prior endovascular thrombectomy procedures did not correlate with mean PAP (F-value = 1.10, p = 0.30) nor was it associated with pulmonary hypertension (odds ratio = 0.92, p = 0.17). Conclusions Prior endovascular arteriovenous graft thrombectomies were not associated with pulmonary hypertension or increased mean PAP in end-stage renal disease patients on maintenance hemodialysis.

    Restless legs syndrome (RLS) is common among dialysis patients, with a reported prevalence of 6-60%. The prevalence of RLS in Syrian patients on hemodialysis (HD) is not known. The purpose of this study is to determine the prevalence of RLS in patients on regular HD, and to find the possible correlation between the presence of RLS and demographic, clinical, and biochemical factors. One hundred and twenty-three patients (male/female = 70/53, mean age = 41.95 ± 15.11 years) on HD therapy at the Aleppo University Hospital were enrolled into the study. RLS was diagnosed based on criteria established by the International Restless Legs Syn-drome Study Group (IRLSSG). Data procured were compared between patients with and without RLS. Applying the IRLSSG criteria for the diagnosis, RLS was seen in 20.3% of the study pa-tients. No significant difference in age, gender, and intake of nicotine and caffeine was found between patients with and without the RLS. Similarly, there was no difference between the two groups in the duration of end-stage renal disease (ESRD), the period of dialysis dependence, dialysis adequacy, urea and creatinine levels, and the presence of anemia. The co-morbidities and the use of drugs also did not differ in the two groups. Our study suggests that the high prevalence of RLS among patients on HD requires careful attention and correct diagnosis can lead to better therapy and better quality of life. The pathogenesis of RLS is not clear and further studies are required to identify any possible cause as well as to discover the impact of this syndrome on sleep, quality of life, and possibly other complications such as cardiovasculare disease.

    Dialysis-dependent chronic kidney disease (CKD) is an expanding problem for healthcare systems worldwide. The prevalence of end-stage renal disease (ESRD) has increased by 20% since 2000 and stands at 1699 per million people in the USA. ESRD is associated with an increased risk of cardiovascular comorbidity, increased severity of cardiovascular disease, and an adjusted all-cause mortality rate that is 6.4-7.8-fold higher than the general population. These patients may present electively or emergently for surgery related to, or remote from, the CKD. In any perioperative setting, the patient with hemodialysis-dependent CKD represents a significant clinical challenge, and successful management of these patients requires effective cooperation and communication between nephrology, anesthesia, and surgical staff. The ESRD patient's nephrologist will have the best knowledge of their medical history, comorbidities, and future management goals and may have been the clinician who instigated the referral for the surgery, e.g., for parathyroidectomy, vascular access surgery, nephrectomy or renal transplantation. As such, they are in an ideal position to contribute to, or coordinate, early preoperative medical optimization of the patient and also to provide advice during postoperative recovery and rehabilitation. In this article, we provide an overview of some of the key aspects of managing these patients successfully during the perioperative period. We propose the integration of cardiopulmonary exercise testing and cardiovascular optimization into the care of these high-risk patients and provide an overview of the importance of maintaining microvascular perfusion and the role of viscosity in preserving the capillary perfusion network.

    Kidney failure affects different aspects of normal life. Among different manifestations, sleep problem can be considered as a common complaint of ESRD (End Stage Renal Disease) patients. In this study, we aimed to investigate the interrelationship between sleep disorders in ESRD patients and their characteristics. Through a cross-sectional study (2010-2011), 88 ESRD patients undergoing maintenance hemodialysis thrice weekly were recruited to enter the study. We used a self-administered questionnaire into which the data were reflected. The patients selected their specific sleep disorders using a nine-item scale while the Epworth Sleepiness Scale (ESS) determined both the presence and severity of sleep disorders. The data was finally analyzed with their baseline characteristics, dialysis characteristics, medication/stimulants use, and clinical and biochemical parameters. Over 95% of the patients had, at least, one specific sleep disorder while the ESS revealed 36.36% of patients as normal, 59.09% as having mild sleep disorders, and 4.54% as having moderate to severe sleep disorders. Sleep disorders were significantly correlated with older ages (P=0.035), dialysis dose (P=0.001), blood creatinine levels (P=0.037), upper airways obstruction (P=0.035), hepatomegaly (P=0.006), hepatic failure (P=0.001), higher blood TSH levels (P=0.039), history of hypothyroidism (P=0.005), and the use of levodopa (P=0.004), anti-hypertensive medications (P=0.006), benzodiazepines (P=0.006), Eprex (Erythropoietin) (P=0.001), Venofer (Iron Sucrose Injection) (P=0.013), and phosphate-binders agents (P=0.018). Sleep disorders are common findings among ESRD patients and seem to be a more complicated issue than a simple accumulation of the wastes products in the body. Whatever the causes of sleep disorders are, disorder-specific treatments should be considered. PMID:27107522

    Purple urine bag syndrome (PUBS) is an uncommon disorder, in which the plastic disposable urinary catheter bag turns purple or blue following hours or days of urinary catheterization. The purple discoloration results from indirubin dissolved in the plastic mixing with indigo in the urine. Bacteria possessing indoxyl sulfatase degrade indoxyl sulfate into indirubin and indigo. Indoxyl sulfate is derived from the metabolism of tryptophan. PUBS usually occurs in chronic catheterized elderly women who are constipated and poorly ambulant. The clinical course is benign and rarely causes sepsis. This investigation reports a 61-year-old female diabetic patient with end-stage renal disease on maintenance hemodialysis, who had two episodes of blue or purple urine bag discoloration. The urine culture of the first episode yielded Klebsiella pneumoniae, whereas that of the second episode yielded Escherichia coli, Enterococcus faecalis, and Proteus vulgaris. Both episodes resolved following oral antibiotics treatment and placement of new foley catheters. To our knowledge, this is the first recorded case of PUBS in a dialysis patient.

    Background and objectives Little is known about patients receiving dialysis who respond to satisfaction and experience of care surveys and those who do not respond, nor is much known about the corollaries of satisfaction. This study examined factors predicting response to Dialysis Clinic, Inc. (DCI)’s patient satisfaction survey and factors associated with higher satisfaction among responders. Design, setting, participants, & measurement A total of 10,628 patients receiving in-center hemodialysis care at 201 DCI facilities between January 1, 2011, and December 31, 2011, aged ≥18 years, treated during the survey administration window, and at the facility for ≥3 months before survey administration. Primary outcome was response to at least one of the nine survey questions; secondary outcome was overall satisfaction with care. Results Response rate was 77.3%. In adjusted logistic regression (odds ratios with 95% confidence intervals), race other than black (white race, 1.23 [1.10 to 1.37]), missed treatments (1.16 [1.02 to 1.32]) or shortened treatments (≥5 treatments, 1.40 [1.22 to 1.60]), more hospital days (>3 days in the last 3 months, 1.89 [1.66 to 2.15]), and lower serum albumin (albumin level <3.5 g/dl, 1.4 [1.28 to 1.73]) all independently predicted nonresponse. In adjusted linear regression, the following were more satisfied with care: older patients (age ≥63 years, 1.84 [1.78 to 1.90]; age <63 years, 1.91 [1.86 to 1.97]; P<0.001), white patients (1.76 [1.71 to 1.81]) versus black patients (1.93 [1.88 to 1.99]) or those of other race (1.93 [1.83 to 2.03]) (P<0.001), patients with shorter duration of dialysis (≤2.5 years, 1.79 [1.73 to 1.84]; >2.5 years, 1.96 [1.91 to 2.02]; P<0.001), patients who had missed one or fewer treatments (1.83 [1.78 to 1.88]) versus those who had missed more than one treatment (1.92 [1.85 to 1.98]; P=0.002) and those who had shortened treatment (for one treatment or less, 1.84 [1.77 to 1.90]; for two to four treatments, 1

    Background: Fatigue is considered as a major problem in hemodialysis patients and can impair their quality of life. The purpose of this study was to investigate the effectiveness of acupressure on fatigue in hemodialysis patients. Materials and Methods: This is a clinical trial study in which 96 hemodialysis patients participated. Patients were randomly assigned into acupressure, placebo, and control groups (32 subjects fulfilling the inclusion criteria assigned to each group). The measures included the form of demographic characteristics, visual analog scale of fatigue, and Piper Fatigue Scale. Patients in the acupressure and placebo groups received acupressure intervention during the early 2 h of dialysis on six acupoints with massage for 20 min/day, 3 days per week for 4 weeks. In the placebo group, acupressure intervention was performed as mentioned above with a distance of 1 cm away from the actual intervention site. Patients in the control group received routine unit care only. Chi- quare test, Kruskal-Wallis, paired t-test, one-way analysis of variance (ANOVA), and Duncan test were used for data analysis. Results: One-way ANOVA tests showed significant differences in the total mean score of fatigue and fatigue mean scores in the behavioral, emotional, sensory, and cognitive dimensions in the acupressure, placebo, and control groups. Conclusion: The results of this study showed that acupressure may reduce fatigue in hemodialysis patients, and use of this non-pharmacologic technique for hemodialysis nurses is suggested.

    Background and objectives: The severity of liver disease among hepatitis C patients on hemodialysis is controversial. The aim of this study was to compare the clinical, biochemical, and liver histologic characteristics of hepatitis C virus (HCV) in hemodialysis patients and in those with normal renal function. Design, setting, participants, & measurements: A case-control study was carried out with 36 HCV patients on hemodialysis and 37 HCV patients with normal renal function matched for gender, age at infection, and estimated time of infection. Results: HCV patients on hemodialysis had lower levels of alanina aminotransferase and lower viral load. Hepatic fibrosis was significantly higher in the patients with normal renal function (73%) than in hemodialysis patients (47.2%, P < 0.025); the same was observed for inflammatory activity (control group 59.5% versus hemodialysis patients 27.7%, P = 0.003). In addition, the risk of tissue inflammation was four times lower in hemodialysis patients (odds ratio = 0.23, P < 0.004), and severe inflammatory activity on biopsy was the only independent risk factor for fibrosis (P < 0.001). Conclusions: The lower biochemical and inflammatory activities observed in hemodialysis patients suggest that hemodialysis and uremia may have a protective role against progression of the disease caused by HCV.

    Abstract Mastocytosis is a heterogeneous group of diseases with a young median age at diagnosis. Usually indolent and self-limited in childhood, the disease can exhibit aggressive progression in mid-adulthood. Our objectives were to describe the characteristics of the disease when diagnosed among elderly patients, for which rare data are available. The French Reference Center conducted a retrospective multicenter study on 53 patients with mastocytosis >69 years of age, to describe their clinical, biological, and genetic features. The median age of our cohort of patients was 75 years. Mastocytosis variants included were cutaneous (n = 1), indolent systemic (n = 5), aggressive systemic (n = 11), associated with a hematological non-mast cell disease (n = 34), and mast cell leukemia (n = 2). Clinical manifestations were predominantly mast cell activation symptoms (75.5%), poor performance status (50.9%), hepatosplenomegaly (50.9%), skin involvement (49.1%), osteoporosis (47.2%), and portal hypertension and ascites (26.4%). The main biological features were anemia (79.2%), thrombocytopenia (50.9%), leucopenia (20.8%), and liver enzyme abnormalities (32.1%). Of the 40 patients tested, 34 (85%), 2 (5%), and 4 (10%) exhibited the KIT D816V mutant, other KIT mutations and the wild-type form of the KIT gene, respectively. Additional sequencing detected significant genetic defects in 17 of 26 (65.3%) of the patients with associated hematological non-mast cell disease, including TET2, SRSF2, IDH2, and ASLX1 mutations. Death occurred in 19 (35.8%) patients, within a median delay of 9 months, despite the different treatment options available. Mastocytosis among elderly patients has a challenging early detection, rare skin involvement, and/or limited skin disease; it is heterogeneous and has often an aggressive presentation with nonfortuitous associated myeloid lineage malignant clones, and thus a poor overall prognosis.

    Background and Aim. Depression is the most common psychological disorder in hemodialysis patients which decreases their quality of life and increases the mortality. This study was conducted to assess the effect of regular exercise on depression in hemodialysis patients. Methods. In a randomized clinical trial, 51 hemodialysis patients were allocated in two groups. Beck Depression Inventory (BDI) scale was used to assessing depression rate in participants. Designed program was educated using poster and face-to-face methods for case group. Intervention was carried out three times a week for ten weeks. At the beginning and the end of the study, depression rate of the subjects was assessed. Data was analyzed by SPSS16 software and descriptive and inferential statistics. Findings. According to the results of this study, there were no differences between case and control groups in depression rate at the beginning of the study, but there was significant difference after intervention (P = 0.016). In the beginning of the study, the mean and SD of depression in case group were 23.8 ± 9.29 and reduced to 11.07 ± 12.64 at the end (P < 0.001). Conclusion. The regular exercise program could reduce the depression in hemodialysis patients; therefore it is suggested for training this program for hemodialysis patients. This trial is registered with Iranian Registry of Clinical Trial (IRCT) number IRCT201205159763N1. PMID:27347502

    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 evaluated the effects of end stage chronic renal failure (CRF) on auditory function and changes in auditory function following a single session of hemodialysis. The experimental group included 31 patients with end-stage renal failure on chronic hemodialysis. The control group consisted of 31 healthy volunteers. The patients were examined prior to and following a session of hemodialysis. Measurements included pure tone audiometry, tympanometry and acoustic reflex measurements, auditory brainstem responses (ABR), and blood now chemistry parameters. Controls underwent the same test battery, with the exception of biochemical and hematological assessment. Prior to hemodialysis sessions, all ABR latencies except interpeak latency I-III were significantly prolonged in the experimental group. A comparison between controls and the experimental group following hemodialysis indicated that wave V absolute latency and interpeak latencies III-V and I-V were significantly prolonged in the slow repetition rate paradigm. In the fast repetition rate, absolute latencies of waves I and V and III-V interpeak latencies were prolonged in the experimental group. Comparison of ABR recordings prior to and following hemodialysis showed overall significant difference between the measures. Post hoc analysis showed a significant improvement in wave I and V latencies in the slow repetition rate and wave V latency in the fast repetition rate. This study showed that neural conduction along the auditory pathway is delayed in patients with end stage CRF as compared to healthy subjects. Dialysis sessions improve overall neural auditory function. However, patients with end stage CRF show delayed conduction even after a session of hemodialysis. PMID:18569911

    Background: In India the incidence of end stage renal disease (ESRD) is increasing day by day and the option for the treatment of ESRD is dialysis or transplantation. In the present scenario, due to the cost of treatment normal people can afford only hemodialysis rather than transplantation. Since the cost of hemodialysis differs across the country, research is needed to evaluate its exact cost. Aim: This study is to analyze the healthcare cost of hemodialysis in a private hospital of South India. Materials and Methods: This is a prospective, observational study carried out in a tertiary care hospital. Patients who are undergoing routine hemodialysis in this hospital were selected for the study. Patient data as well as cost details were collected for a period of six months. Thirty patients were selected for the study and a total of 2160 dialysis sessions were studied. Patient perspective was taken for the analysis of cost. Both direct and indirect costs were analyzed. This includes cost of dialysis, investigations, erythropoietin, food, transportation, lost wages etc. Socioeconomic status of the patient was also studied. Result: The total cost per session was found to be around Rs. 4500. Fifty six percent contributes direct medical cost whereas 20% contributes direct non medical cost. Twenty four percent cost was due to indirect costs. Since the patients are paying from their own pocket, only the upper or upper middle class patient can undergo hemodialysis regularly. Conclusion: These findings are important to find out the impact of cost of hemodialysis on patients suffering from ESRD. Further studies related to costs and outcome, otherwise known as pharmacoeconomic studies, are needed to analyze the pros and cons of renal replacement therapy and to improve the quality of life of ESRD patients. Thus pharmacoeconomical studies are needed to realize that government has to take initiative to provide insurance or reimbursement for the common people. PMID:22557920

    The benefits of an arteriovenous fistula (AVF) as the preferred vascular access for hemodialysis have been clearly demonstrated. However, only about 20% of patients in the United States initiate hemodialysis with an AVF. In this study, we assessed whether disparities exist in the type of first hemodialysis access placed prior to dialysis start (rather than that used at dialysis initiation), to detect whether certain disadvantaged groups might have lower likelihood of AVF placement. Study cohort of 118,767 incident hemodialysis patients ≥67 years of age (1/2005-12/2008) derived from the United States Renal Data System was linked with Medicare claims data to identify the type of initial access placed predialysis. We used logistic regression model with outcome being the initial predialysis placement of an AVF as opposed to an arteriovenous graft or a central venous catheter. Increasing age, female sex, black race, lower body mass index, urban location, certain comorbidities, and shorter pre-end-stage renal disease nephrology care are all associated with a significantly lower likelihood of AVF placement as initial access predialysis. Our study suggests the presence of significant disparities in the placement of an AVF as initial hemodialysis vascular access. We suggest that additional attention should be paid to these patient groups to improve disparities by patient education, earlier referral, and close follow-up.

    Current Kidney Disease Improving Global Outcomes guidelines for chronic kidney disease-mineral and bone disorder recommend maintaining the PTH level between 2 and 9 times the upper limit of normal. PTH levels function as a surrogate for bone turnover to differentiate forms of renal osteodystrophy. Vitamin D receptor agonists are primarily used to treat osteitis fibrosa in hemodialysis patients. However, there is concern that overtreatment may put HD patients at risk for adynamic bone disease, which has been associated with fracture and vascular calcification. This raises the issue as to whether "we use too much vitamin D in hemodialysis patients." PMID:27075415

    Background: 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. Objectives: This study examined the relationship between spiritual well-being and quality of sleep in hemodialysis patients in Isfahan, Iran. Patients and Methods: 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. Results: 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). Conclusions: 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. PMID:25237580

    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).

    The ageing of the population is associated with an increase in the incidence of chronic renal failure. Management of the condition must be adapted to the specificities linked to ageing. With end-stage renal failure, haemodialysis is a substitution technique offered under certain conditions. The central role of the caregivers is to support and guide the elderly person along their care pathway. Faced with a reduced life expectancy, the aim of all concerned is to strike a balance between an effective treatment and quality of life. PMID:26805642

    To investigate the effect of partial correction of anemia in patients maintained by chronic intermittent hemodialysis on exercise capacity, patients underwent a bicycle acido-ergometry before and after treatment with recombinant human erythropoietin. The results demonstrate a (subjective) improvement of exercise capacity without any evidence for that in the pH values.

    Infective endocarditis (IE) in elderly patients presents a unique diagnostic and therapeutic challenge. Atypical presentations frequently lead to delayed diagnosis and poor outcome. IE in elderly persons is somewhat more common among men. Underlying degenerative valvular disease, mitral valve prolapse, and the presence of a prosthetic valve are important risk factors predisposing elderly persons to IE. Streptococci and staphylococci are the predominant organisms, which are recovered from approximately 80% of elderly patients with IE. In older patients, IE occurs somewhat more frequently on the mitral valve than it does on the aortic valve. The presence of calcific valvular lesions and the prosthetic valves often confound the echocardiographic findings in elderly patients. A high index of suspicion and an aggressive diagnostic approach are required to ensure timely diagnosis and appropriate therapy.

    Background: Atherosclerosis is the leading cause of death in hemodialysis patients. These patients are also very prone to L-carnitine deficiency due to kidney disease. In this clinical trial, we investigated the effect of oral L-carnitine on endothelial function of these patients. Materials ans Methods: We studied 31 adult chronic hemodialysis patients in our center and divided them into two groups. The first group (n = 20) received 1500 mg/dialysis interval (every other day) oral L-carnitine. The control group (n = 11) received placebo for one month. Ultrasonographic measurements of flow mediated dilation and carotid intima-media thickness were performed before and after one month of L-carnitine and placebo therapy. Results: This study showed that after one month of L-carnitine or placebo therapy there was no significant improvement in flow mediated dilation (p = 0.80 and p = 0.59, respectively) or decrease in carotid intima-media thickness (p = 0.12 and p = 0.50, respectively). Conclusions: Our study revealed that one month of oral L-carnitine therapy did not improve endothelial function in hemodialysis patients. Long-term studies with large sample size using intravenous form and higher doses of the drug are required to clarify the questionable role of L-carnitine in hemodialysis patients. PMID:23626603

    Although symptoms are common and frequently severe in patients on maintenance hemodialysis, little is known about the relationship between cultural background and symptom burden. The aim of this study was to explore differences in the prevalence and severity of symptoms between American and Italian hemodialysis patients. We administered the 30-item Dialysis Symptom Index to American and Italian patients receiving maintenance hemodialysis during routine dialysis sessions. The prevalence and severity of individual symptoms were compared between patient populations, adjusting for multiple comparisons. Multivariable logistic regression and ordinal logistic regression were used to assess the independent associations of cultural background with the prevalence and severity of symptoms, respectively. We enrolled 75 American and 61 Italian patients. American patients were more likely to be black (36% vs. 0%, P<0.001) and diabetic (53% vs. 13%, P<0.001). Italian patients were more likely to report decreased interest in sex, decreased sexual arousal, feeling nervous, feeling irritable, and worrying (P<0.001, respectively). Adjustment for demographic and clinical variables had no impact on these cultural differences in symptom prevalence. The median severity of 11 symptoms including muscle soreness, muscle cramps, and itching was greater among Americans (P<0.001, respectively), although nearly all of these differences were rendered nonstatistically significant with adjustment for race, diabetes, and/or Kt/V. Italian patients receiving chronic hemodialysis report a greater burden of symptoms than American patients, particularly those related to sexual dysfunction and psychosocial distress. These findings suggest that cultural background may affect adaptation to chronic hemodialysis therapy.

    Summary Background and objectives Vascular calcification is a major cause of morbidity and mortality in dialysis patients. Human and animal studies indicate that sodium thiosulfate (STS) may prevent the progression of vascular calcifications. The pharmacokinetics of STS in hemodialysis patients has not been investigated yet. Design, setting, participants, & measurements STS was given intravenously to 10 hemodialysis patients on- and off-hemodialysis. Additionally, STS was applied to 9 healthy volunteers once intravenously and once orally. Thiosulfate concentrations were measured by using a specific and sensitive HPLC method. Results In volunteers and patients, mean endogenous thiosulfate baseline concentrations were 5.5 ± 1.82 versus 7.1 ± 2.7 μmol/L. Renal clearance was high in volunteers (1.86 ± 0.45 ml/min per kg) and reflected GFR. Nonrenal clearance was slightly, but not significantly, higher in volunteers (2.25 ± 0.32 ml/min per kg) than in anuric patients (2.04 ± 0.72 ml/min per kg). Hemodialysis clearance of STS was 2.62 ± 1.01 ml/min per kg. On the basis of the nonrenal clearance and the thiosulfate steady-state serum concentrations, a mean endogenous thiosulfate generation rate of 14.6 nmol/min per kg was calculated in patients. After oral application, only 4% of STS was recovered in urine of volunteers, reflecting a low bioavailability of 7.6% (0.8% to 26%). Conclusions Given the low and variable bioavailability of oral STS, only intravenous STS should be prescribed today. The biologic relevance of the high hemodialysis clearance for the optimal time point of STS dosing awaits clarification of the mechanisms of action of STS. PMID:21566113

    Geographic remoteness has been found to influence health-related outcomes negatively. As reported in the literature, rural dialysis patients have a higher risk of mortality with increasing travel distance to dialysis units. However, few studies have focused on the impact of travel distances on the development of dialysis complications. We utilized a prospectively collected chronic hemodialysis patient cohort from a rural regional hospital for analysis. Data on demographics, comorbidities, and serum laboratory results were obtained. Correlation analyses between travel distance to dialysis units and dialysis complications were conducted, and significantly correlated parameters were entered into multivariate logistic regression models to determine their exact associations. A total of 46 rural chronic hemodialysis patients were enrolled, with an average age higher than others in the literature. Significant correlation was found between travel distance and serum hemoglobin levels (R(2) = -0.34, P value = 0.029). Multivariate logistic regression found that every 1 km increase in travel distance was associated with an increased risk of anemia (hemoglobin <9 g/dL) (odds ratio 1.46; P value = 0.01). Sensitivity analyses further showed that the associated risk was partially attenuated by serum albumin (odds ratio 1.83; P value = 0.07) and ferritin (odds ratio 1.39; P value = 0.08) levels. This is the first study to demonstrate the association between increased travel distance to dialysis units and the risk of anemia in chronic dialysis patients, especially elderly. Malnutrition, inflammation, and atherosclerosis syndrome could be partially responsible for the observed association. Further research is required to confirm our findings.

    Because hemodialysis treatment has a limited ability to remove phosphorus, dialysis patients must restrict dietary phosphorus intake and use phosphorus binding medication. Among patients with restricted dietary phosphorus intake (1000 mg/d), phosphorus binders must bind about 250 mg of excess phosphorus per day and among patients with more typical phosphorus intake (1500 mg/d), binders must bind about 750 mg per day. To determine the phosphorus binding capacity of binder prescriptions among American hemodialysis patients, we undertook a cross-sectional study of a random sample of in-center chronic hemodialysis patients. We obtained data for one randomly selected patient from 244 facilities nationwide. About one-third of patients had hyperphosphatemia (serum phosphorus level > 5.5 mg/dL). Among the 224 patients prescribed binders, the mean phosphorus binding capacity was 256 mg/d (SD 143). 59% of prescriptions had insufficient binding capacity for restricted dietary phosphorus intake, and 100% had insufficient binding capacity for typical dietary phosphorus intake. Patients using two binders had a higher binding capacity than patients using one binder (451 vs. 236 mg/d, p <0.001). A majority of binder prescriptions have insufficient binding capacity to maintain phosphorus balance. Use of two binders results in higher binder capacity. Further work is needed to understand the impact of binder prescriptions on mineral balance and metabolism and to determine the value of substantially increasing binder prescriptions. PMID:23013171

Bloodstream infections are the second cause of death in patients in chronic hemodialysis (CHD), and the knowledge of the epidemiology is useful to establish proper empiric therapies. The aim of this study was to evaluate the frequency and distribution of microorganisms, in bacteremia and fungemia in 530 patients in CHD. Two hundred and forty eight blood culture series from 114 patients with suspected bacteremia were processed; 44% of them were positive from which 71% (n=78) were clinically significative and belonged to 58 patients. Sixty eight percent of these isolates were gram-positive cocci (n:53), and 22% gram-negative rods (n:17). Staphylococcus aureus was the most prevalent pathogen showing 23% of methicillin-resistance. Candida spp. was the fourth pathogen most common in frequency.

    Malnutrition is frequent in hemodialysis (HD) patients. The HEMO study has shown a progressive decline of nutritional markers, such as body weight, albuminemia and protein intake, in prevalent hemodialysis patients during a 3-year follow-up. In incident dialysis patients, nutritional status usually improves during the first year of HD treatment. Opposite to the HEMO findings, we have shown that nutritional stability was achieved during a 5 year follow-up with sequential long hour dialysis (3 x 6-8 hours/week). Energy and protein intakes are related to the dialysis dose. Moreover, several studies show the nutritional consequences of changing the dialysis prescriptions. The switch from conventional HD to short daily dialysis improves significantly protein and energy intake and albuminemia. Also, increasing treatment time increases significantly the body weight after several months. One of the hypothesis for this effect is that uremia-related middle molecules compromise the patient appetite. Increasing dialysis time or frequency may decrease the level or the time of exposition to these molecules. However, the beneficial effect of hemodiafiltration on HD patients' nutritional status is not spectacular. Another hypothesis is the role of extra-cellular fluid excess and its relationship with inflammation that is deleterious for nutrition. In conclusion, dialysis adequacy is a mandatory prerequisite when facing a malnourished HD patient. Increasing time or frequency must be part of the therapeutic thought in such situation.

    Background: Chronic renal failure is among the chronic disease which due to persistence of the disease and long treatment process has various effects on the physiological, psychological, functional ability, lifestyle changes, and independence status of the patient and his family. This may result in the burden feeling in caregivers. According to the importance of the subject, this study is to assess the level of caregiver burden in caregivers of hemodialysis patients. Methods: This is a cross-sectional analytical descriptive study that was conducted in 2014 on the caregivers of hemodialysis patients. Research instruments were consisted of two parts: demographic data check list and caregiver burden questionnaire. Data were analyzed by SPSS statistical software and Pearson correlation coefficient tests. A p value of less than 0.05 was considered statistically significant. Results: In this study, 72.5% of caregivers reported moderate to severe levels of caregiver burden. A significant relationship was observed between gender of the patient with caregiver burden score of (p=0.031) and type of the income with caregiver burden score of (p=0.000). Caregivers of male patients and patients with inadequate income had a higher caregiver burden score. Conclusions: Our results showed that more than half of the caregivers of hemodialysis patients had moderate to severe levels of caregiver burden, therefore it is worthy that health officials and nurses pay special attention to this issue by communicating with these patients and their caregivers.

    While the classic electrocardiographic (EKG) findings of hyperkalemia are well known to clinicians, the association between hyperkalemia and bradycardia is not widely appreciated. Three cases of profound bradycardia due to hyperkalemia in patients with End Stage Renal Disease (ESRD) on hemodialysis are described to provide a base for discussion of specific issues in the management of such patients. The patients presented with hyperkalemia and severe bradycardia that did not improve after administration of atropine. Urgent hemodialysis in two cases led to resolution of the bradycardia. In the third case, the failure to recognize that bradycardia was the consequence of the hyperkalemia led to unnecessary interventions and delays in initiating dialysis. These cases highlight the causal relation between hyperkalemia and bradycardia in ESRD patients and emphasize the need for increased awareness of this association.

    This study aims to determine the prevalence, types, and associated factors for the use of herbal remedies in hemodialysis patients. Two hundred participants were selected by stratified sampling and were systematically interviewed. One hundred and twenty-six patients (63%) had used herbal remedies some time since their initiation of dialysis treatment. The users of herbal remedies had a significantly older age than nonusers, but no other significant differences were observed. The most prevalent complaints that led to herbal remedies use were gastroenterological complaints, flushing, and excessive thirst. Cichorium intybus, Borage officinalis, Mentha longifolia, and Matricaria recutita were the most prevalently used herbs in our patients. More study should be done on safety and efficacy of these herbs for hemodialysis patients. PMID:24241097

    Social and ecologic factors, such as residential segregation, are determinants of health in the general population, but how these factors associate with outcomes among patients with ESRD is not well understood. Here, we examined associations of income inequality and residence, as social determinants of health, with survival among black and white patients with ESRD. We merged U.S. Renal Data System data from 589,036 patients who started hemodialysis from 2000 through 2008 with race-specific median household income data from the Census Bureau. We used Gini Index coefficients to assess income distributional inequality and the Dissimilarity Index to determine residential segregation. Black patients lived in areas of lower median household income compared with white patients ($26,742 versus $41,922; P<0.001). Residence in areas with higher median household income was associated with improved survival. Among whites, income inequality was associated with mortality. Among blacks exclusively, residence in highly segregated areas was associated with increased mortality. In conclusion, black hemodialysis patients in the United States are particularly susceptible to gradients in income and residential segregation. Interventions directed at highly segregated black neighborhoods might favorably affect hemodialysis patient outcomes.

    One quarter of all hemodialysis patients will succumb to sudden cardiac death (SCD), a rate far exceeding that observed in the general population. A high prevalence of atherosclerotic coronary artery disease amongst patients with end-stage kidney disease (ESKD) partly explains this exaggerated risk. However, uremia and dialysis related factors are also of critical importance. Interventions aimed at preventing SCD have been inadequately studied in patients with ESKD. Data extrapolated from non-renal populations cannot necessarily be applied to hemodialysis patients, who possess relatively unique risk factors for SCD including "uremic cardiomyopathy", electrolyte shifts, fluctuations in intravascular volume and derangements of mineral and bone metabolism. Pending data derived from proposed randomized controlled clinical trials, critical appraisal of existing evidence and the selective application of guidelines developed for the general population to dialysis patients are required if therapeutic nihilism, or excessive intervention, are to be avoided. We discuss the evidence supporting a role for medical therapies, dialysis prescription refinements, revascularization procedures and electrical therapies as potential interventions to prevent SCD amongst hemodialysis patients. Based on current best available evidence, we present suggested strategies for the prevention of arrhythmia-mediated death in this highly vulnerable patient population. PMID:24720456

    Studies were performed to investigate the relationship between serum interleukin-6 (IL-6) and the nutritional status in chronic hemodialysis patients. Serum IL-6 in 45 patients (21 men and 24 women), each with chronic renal failure and having undergone hemodialysis for more than 3 years, was measured before and after a dialysis session. The nutritional status of each patient was evaluated by measuring body mass index (BMI), body weight loss for 3 years, midarm muscle area (MAMA), serum albumin, prealbumin, and insulin-like growth factor-1. Serum IL-6 was significantly higher in the patients undergoing hemodialysis (11.7 +/- 2.8 pg/mL) than in healthy volunteers (< 0.6 pg/mL). There was no further increase in serum IL-6 after a dialysis session when the extracellular water volume was corrected by the ultrafiltrate volume. Predialytic serum IL-6 was significantly correlated with serum albumin (r = -0.4, P = 0.006), cholinesterase (r = -0.51, P = 0.001), body weight change for 3 years (r = -0.48, P = 0.001) and MAMA r = -0.39, P = 0.05). With the patients divided into two groups, a high serum IL-6 (>10 pg/mL) group and low serum IL-6 (<10 pg/mL) group, the body weight loss for 3 years (-4.60% +/- 1.39% v 0.76 +/- 0.75%, P < 0.01) was significantly higher, and the serum albumin level (3.66 +/- 0.10 g/dL v 3.96 +/- 0.05 g/dL, P < 0.05) was significantly lower in those patients with high serum IL-6 than in those with low serum IL-6. The results of a multiple regression analysis indicated that the serum IL-6 level was dependent on the duration of hemodialysis, age, and the dialysis membrane properties. These results suggest that the nutritional status in chronic hemodialysis patients was affected, at least in part, by the circulating IL-6 level. Multiple factors, such as long-term hemodialysis, aging, and the use of a regenerated cellulose membrane dialyzer, were associated with this increased level of IL-6.

    Objective It is unknown whether muscle wasting accounts for impaired physical function in adults on maintenance hemodialysis (MHD). Design Observational study Setting Outpatient dialysis units and a fall clinic Subjects 108 MHD and 122 elderly non-hemodialysis (non-HD) participants Exposure variable Mid-thigh muscle area was measured by magnetic resonance imaging. Main outcome measure Physical function was measured by distance walked in six minutes (6MW). Results Compared to non-HD elderly participants, MHD participants were younger (49.2 ± 15.8 yrs vs. 75.3 ± 7.1 yrs, p<0.001) and had higher mid-thigh muscle area (106.2 ± 26.8 cm2 vs. 96.1 ± 21.1 cm2, p=0.002). However, the 6MW distance was lower in MHD participants (322.9 ± 110.4 m vs. 409.0 ± 128.3 m, p<0.001). In multiple regression analysis adjusted for demographics, comorbid conditions and mid-thigh muscle area, MHD patients walked significantly less distance (−117 m, 95% −177 to −56 m, p<0.001) than the non-HD elderly. Conclusions Even when compared to elderly non-HD participants, younger MHD participants have poorer physical function that was not explained by muscle mass or comorbid conditions. We speculate that the uremic milieu may impair muscle function independent of muscle mass. The mechanism of impaired muscle function in uremia needs to be established in future studies.

    The aim of this study was to obtain information that would enable caregivers to provide the necessary psychological care for hemodialysis patients. A total of 608 hemodialysis patients completed the questionnaire of the Neuroticism, Extroversion, Openness-Five Factor Inventory and were subsequently classified by personality types using cluster analysis. In comparison to the norms for the general Japanese adult population, the four-dimensional average of extroversion, openness, agreeableness, and conscientiousness among hemodialysis patients was significantly lower (P < 0.001), especially for openness. The openness score correlated with each of the following: age (P < 0.001), employment (P < 0.01), and diabetes (P < 0.001). Four personality types were defined based on these dimensions. High scores for agreeableness, extroversion and conscientiousness characterized the agreeable type (22.6%). The patients in this type will likely accept their own experiences in a positive manner. Submissive types (22.0%) received the lowest scores for conscientiousness, though extroversion, openness, and agreeableness were also low. It is necessary to enhance a sense of independence and responsibility in patients with submissive type personalities. Sensitive types (21.5%) were characterized by the highest neuroticism scores and low scores for the other four dimensions. The patients in this type were likely to be persistent with changes in conditions. The last type was the balanced type (33.9%), which was defined by scores within mean range. In clinical practice, it is particularly important that the submissive and sensitive types should receive appropriate mental health care.

    There is a high prevalence of protein-energy malnutrition in the end-stage renal disease population. There are a number of causes of malnutrition in hemodialysis patients, which can often be directly linked to the uremic state. Laboratory measures including albumin, prealbumin, and serum cholesterol, as well as anthropometric measures, have been used to assess malnutrition in this patient population. There is, however, no single accepted measure of malnutrition in patients with chronic kidney disease. Failure to achieve adequate nutritional goals may lead to protein-energy malnutrition, which has been linked to decreased survival. Several studies have also shown a direct association between psychosocial variables, including depression, and the nutritional status of hemodialysis patients, in particular the serum albumin concentration. Interventions such as oral nutritional supplements or intradialytic parenteral nutrition may be necessary to improve nutritional status if conservative measures such as nutritional counseling and regular dietician follow-up fail to produce the changes needed to sustain health. In addition, given the potential link between psychological conditions, such as depression, and overall nutritional status, interventions designed to screen for and treat psychiatric disorders may lead to improvements in nutritional status and therefore increased survival rates of patients with end-stage renal disease treated with hemodialysis. Further study is needed to evaluate the association between depression, malnutrition, and survival in patients with chronic kidney disease.

    A half million Americans have ESRD, which puts them at high risk for cardiovascular disease and poor outcomes. Little is known about the epidemiology of atrial fibrillation among patients with ESRD. We analyzed data from annual cohorts (1992 to 2006) of prevalent hemodialysis patients from the United States Renal Data System. In each cohort, we searched 1 year of medical claims for relevant diagnosis codes to determine the prevalence of atrial fibrillation. Among 2.5 million patient observations, 7.7% had atrial fibrillation, with the prevalence increasing 3-fold from 3.5% (1992) to 10.7% (2006). The number of affected patients increased from 3620 to 23,893 (6.6-fold) during this period. Older age, male gender, and several comorbid conditions were associated with increased risk for atrial fibrillation. Compared with otherwise similar Caucasians, the prevalence of atrial fibrillation rates was substantially lower for blacks, Asians, and Native Americans. One-year mortality was twice as high among hemodialysis patients with atrial fibrillation compared with those without (39% versus 19%), and this increased risk was constant during the 15 years of the study. In conclusion, the prevalence of diagnosed atrial fibrillation among patients receiving hemodialysis in the United States is increasing, varies by race, and remains associated with substantially increased mortality. Identifying potentially modifiable risk factors for incident atrial fibrillation requires further investigation.

    Deglutition disorders are frequent in elderly patients and can lead to serious consequences in terms of morbidity and mortality. Despite an easy screening test with the water, they are ignored or underestimated. Moreover, early detection and treatment focused essentially on the adaptation of textures, postures as well as the provision of information and training to all the people involved in feeding the elderly person require few resources and provide a real benefit.

    Kidney failure and hemodialysis are associated with numerous physical and psychological symptoms and complications, some of which can be reduced or eliminated by adequate exercise. Dialysis patients, however, tend to be quite sedentary on average, which can further complicate their physical and mental health. The goal of this study was to investigate perceptions of barriers and motivators for exercise among hemodialysis patients. It was hypothesized that increased barriers would be associated with decreased exercise, and increased motivators would be associated with increased exercise. The results indicated that both motivators and barriers were associated with exercise behavior, with motivators being more salient. Contrary to what has been previously postulated, lack of motivation, as opposed to health-related impairment, appears to be the primary factor impeding dialysis patient exercise practices.

    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.

    The aim of this study was to investigate the relationship between sleep disorders and C-reactive protein (CRP), hallmark of inflammation, and other biomarkers which may alter in hemodialysis patients. Our study included 108 patients who were dialyzed at least for 3 months. Before hemodialysis, blood samples were collected and serum levels of CRP, ferritin, albumin, phosphorus, parathyroid hormone, and hemoglobin were measured. Sleep disorders were confirmed by the presence of at least one of following criteria: insomnia, restless leg syndrome (RLS), obstructive sleep apnea syndrome (OSAS), narcolepsy, nightmare, sleepwalking, and poor sleep. 82.4% of patients demonstrated sleep disorders; insomnia (50%), RLS (32.4%), OSAS (7.4%), narcolepsy (15.7%), nightmare (15.7%), sleepwalking (0.9%), and poor sleep (71.3%). Our results revealed that CRP ≥3.8 μg/ml and advanced age were significantly associated with sleep disorders in these patients (p = 0.004 and p = 0.006, respectively). We concluded that inflammation has a close relation with sleep disorders in hemodialysis patients. PMID:22427289

    Introduction: One of the major causes of mortality in chronic kidney disease (CKD) patients on hemodialysis is premature atherosclerosis. Selenium, a trace element involved in important enzymatic activities inside the body, has protective effects against lipid oxidation and inhibits cholesterol accumulation in blood vessels. Objectives: To determine the effect of selenium supplementation on lipid profile in hemodialysis patients. Patients and Methods: In this double-blinded randomized clinical trial which lasted for 3 months, 84 hemodialysis patients with selenium deficiency were divided into experimental group (received selenium supplementation) or control group (received placebo). Total cholesterol, low-density lipoprotein (LDL-C), high-density lipoprotein (HDL-C), blood urea nitrogen (BUN), creatinine, and selenium level were measured before and after the study. Results: Mean (±SD) serum LDL-C level significantly increased in experimental group from 85.66 (±31.12) to 109.12 (±32.29) mg/dl (P<0.001). Likewise, in control group serum LDL-C significantly increased from 80.55 (±21.13) to 97.05 (±28.07) mg/dl (P<0.001). However, with control of LDL-C effect before and after the study, it was revealed that LDL-C change was not statistically significant (P=0.21). Similarly, total cholesterol and triglyceride levels did not show significant changes before and after the study in any group. Conclusion: Selenium supplementation had no beneficial effect on lipid profile in hemodialysis patients. PMID:27689119

    Sudden sensorineural hearing loss (SSNHL) is being described with increasing incidence among patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD). There are no widely accepted guidelines in the medical literature for the appropriate management of this medical emergency. Administration of systemic steroids remains the mainstay of the management of SSNHL in conjunction with the supportive treatment, in this vulnerable group of patients, as well. However, encouraged by the evolving evidence on the efficacy of the intratympanic steroid injections (ITSI) in the treatment of SSNHL among patients without renal disease--we successfully treated SSNHL in an elderly diabetic with sepsis due to bilateral pneumonitis undergoing regular HD treatment with multiple ITSI and antibiotics resulting in complete recovery of hearing function within 3 months of onset of the first symptoms.

    Background Both depression and cognitive impairment are common in hemodialysis patients, are associated with adverse clinical outcomes, and place an increased burden on health care resources. Study Design Cross-sectional cohort Setting & Participants 241 maintenance hemodialysis patients in the Boston area Predictor Depressive symptomatology, defined by a Center for Epidemiological Studies Depression Scale (CES-D) score of 16 or higher Outcome Performance on a detailed neurocognitive battery Results Mean age was 63.8 years, 49.0% were female, 21.6% were African American, and median dialysis duration was 13.8 months. There were 57 (23.7%) participants with significant depressive symptoms. In multivariable analysis adjusting for age, sex, education and other comorbid conditions, participants with and without depressive symptoms performed similarly on the Mini-Mental State Examination (p=0.4) and tests of memory. However, participants with greater depressive symptoms performed significantly worse on tests assessing processing speed, attention, and executive function, including Trails Making Test B (p=0.02) and Digit-Symbol Coding (p=0.01). Defining depression using a CES-D score ≥18 did not substantially change results. Limitations Cross-sectional design, absence of brain imaging Conclusions Hemodialysis patients with a greater burden of depressive symptoms perform worse on tests of cognition related to processing speed and executive function. Further research is needed to assess the effects of treating depressive symptoms on cognitive performance in dialysis patients. PMID:20673602

    This study examines the effects of 12 months of endurance exercise training (cycling, walking and jogging) on lipid profiles, glucose metabolism, blood pressure, anemia and psychological function in 14 hemodialysis patients. Maximal aerobic capacity (VO2max) increased 18% in the exercisers (p less than 0.01), but did not change in 11 controls. This was associated with a reduction in depression, a decrease in dosages of antihypertensive medications, a significant increase in hematocrit and hemoglobin levels (red cell mass rose, plasma volume did not change), a decrease in plasma triglyceride by 23% (p less than 0.05) and an increase in high-density lipoprotein cholesterol (HDL-C) levels by 21% (p less than 0.01) (both HDL-C and triglyceride levels worsened in the sedentary controls), and an 18% increase in glucose disappearance rates (p less than 0.05) in spite of a 52% decrease in fasting insulin levels (p less than 0.01), suggesting that insulin sensitivity improved. These results demonstrate that some of the complications present in hemodialysis patients may be caused by their sedentary life-style, rather than endstage renal disease itself. This suggests that rehabilitation through exercise is possible for these patients. By reducing coronary risk factors in hemodialysis patients, exercise training may also decrease their heightened morbidity and mortality from atherosclerotic complications. These possibilities need to be examined in a longitudinal study.

    Agrobacterium radiobacter, a Gram-negative bacillus, is recognized as an emerging opportunistic human pathogen that has a propensity to cause infections in patients with indwelling foreign devices. Here, we describe the first reported case of catheter-related bacteremia caused by A. radiobacter in a hemodialysis patient with a long-term tunneled-cuffed hemodialysis catheter. This case shows that A. radiobacter should be included in the list of pathogens that can cause catheter-related bacteremia in hemodialysis patients.

    The purpose of this study was to evaluate the impact of a fatigue management program on 25 hemodialysis patients regarding their level of fatigue and their rate of satisfaction towards knowledge. The study took place inside a hemodialysis unit in a health care facility located in New Brunswick. This research design was pre-experimental. The before-after design, with only one group of subjects, makes it possible to compare the level of fatigue, as well as the rate of satisfaction towards pre- and post-program knowledge. According to the results of our study, it seems that the subjects, after benefiting from a fatigue management program, managed to significantly decrease their level of fatigue and gain satisfaction related to the acquisition of knowledge. Even though our number of participants was small, our research supports the idea that a fatigue management program can meet the need of fatigue management in this population. The results of this study foresee the need to develop a fatigue management program in hemodialysis units and to evaluate its effectiveness in the medium or long term in selecting quasi-experimental studies, including a broader population of patients.

    In recent years there has been a large increase in the areas related to developments in the prevention of diseases, especially in explaining the role of oxidative stress. Lipid peroxidation and oxidative stress contributes to morbidity in hemodialysis (HD) patients. It is therefore relevant to analyze the impact of oxidative stress and its related species (ethylene) immediately after dialysis treatment in order to prevent trauma in the renal failure of elderly patients. In this paper we describe recent progress in laser photoacoustic spectroscopy detection of ethylene in renal failure patients. We have found that HD treatment increases ethylene concentration in the exhaled breath of elderly patients and may intensify oxidative stress.

    Background: Hypervolemia is a major risk factor for hypertension leading to cardiovascular diseases and also a frequent problem in maintenance hemodialysis (MHD) patients. Fluid overload (FO) can be determined by bioimpedance spectroscopy (BIS) which is a new, practical, and non-invasive method. We tried to determine FO by BIS in MHD patients and find out the relationship between FO and clinical features. Material and Methods: We studied 100 MHD patients aged between 20 and 85 years and undergoing hemodialysis three times weekly for minimum one year. By using BIS, we estimated FO and extracellular water (ECW). The patients who exhibited a FO/ECW ratio >15% were considered as FO. Results: Twenty-nine (29.0%) patients had a FO/ECW ratio >15%. In the overhydrated group, the mean pre-hemodialysis systolic blood pressure was 153.3 ± 20.0 mmHg and the mean diastolic blood pressure was 89.1 ± 8.5 mmHg. These were significantly higher than in the non-overhydrated group (113.5 ± 14.5 and 71.0 ± 8.8, p <0.001). FO was significantly correlated with systolic and diastolic blood pressures (r =0.63, p <0.001 and r =0.59, p <0.001). The patients were divided into two groups, i.e. those with cardiothoracic index (CTI) of  >0.5 and those with CTI of ≤0.5. The median FO/ECW ratio was 0.11 L in the former group and 0.08 L in the latter group with a significant difference (p =0.006). Conclusions: Hypervolemia is associated with high blood pressure and left ventricular hypertrophy that should be treated effectively to prevent cardiovascular diseases in MHD patients. BIS is useful to assess hydration status in MHD patients. Hippokratia 2015; 19 (4): 324-331.

    Hepatitis B surface antigen is widely used in hepatitis B virus surveillance; patients who test negative for the antigen are judged to be uninfected. However, occult hepatitis B virus infection has been confirmed with hepatitis B virus DNA at low levels in the liver and peripheral blood in patients positive for hepatitis B core antibody or hepatitis B surface antibody, even if they test negative for hepatitis B surface antigen. To investigate the prevalence of occult hepatitis B virus in hemodialysis patients, we performed cross-sectional analysis of 161 hemodialysis patients in two related institutions for hepatitis B surface antigen, hepatitis B core antibody, and hepatitis B surface antibody. Hepatitis B surface antigen, hepatitis B core antibody, or hepatitis B surface antibody was present in 45 patients (28.0%). Hepatitis B virus DNA was present in six patients (3.7%), all of whom also tested positive for hepatitis B core antibody. Hepatitis B surface antibody positivity was unrelated in only one of the six patients. Four of the six patients were positive for hepatitis B surface antigen; however, two (1.3%) of these with occult hepatitis B virus infection were found to be hepatitis B surface antigen negative. Occult hepatitis B virus infection may be missed in hepatitis B virus surveillance using hepatitis B surface antigen alone; therefore, routine hepatitis B core antibody screening is necessary. Patients who test positive for hepatitis B core antibody should undergo further hepatitis B virus DNA testing to enable accurate hepatitis B virus screening.

    The aim of this study is to describe the characteristics of caregivers of chronic hemodialysis patients, assess their perceived burden and health-related quality of life, and investigate factors influencing this burden. We studied 100 hemodialysis patients and their respective primary caregivers for more than 4 months, measuring quality of life by the Medical Outcomes Survey 36-Item Short-Form Health Survey (SF-36). Subjective burden on caregivers was assessed by the Caregiver Burden scale (score range, 1 to 4; higher values indicate a greater effect). The majority of caregivers were women (84%), married (66%), with a mean age of 46 +/- 2 (SE) years, and of low socioeconomic level. Their main types of relationship with patients were wives (38%) and sons or daughters (27%). Caregiver Mental Health and Vitality were the most affected emotional dimensions on the SF-36 (mean scores, 64.4 +/- 1.8 and 66.6 +/- 1.7, respectively). Mean score of total burden experienced was 2.07 +/- 0.05. Multiple regression analysis showed that independent and significant predictors of burden were Mental Health of the caregiver (R2 = 24%), Vitality of the patient (R2 = 10%), type of relationship of the caregiver (female spouse) (R2 = 5%), and Pain of the caregiver (R2 = 3%). Caregivers of hemodialysis patients may experience a significant burden and an adverse effect on their quality of life. Emotional aspects of caregivers (particularly female spouses) and patients are important predictors of burden. Social support and psychological interventions should be considered to improve caregiver life and patient outcomes. PMID:11920347

    Recent evidence highlights the relationship between metabolic syndrome (MS) and increased risk of cardiovascular (CV) diseases. The overall prevalence of the MS is increased in hemodialysis population. To evaluate the prevalence of the MS and obesity in our hemodialysis (HD) patients, we studied 234 HD patients and 34 patients were excluded from the study due to incomplete data at the time of analysis. For the remaining 200 patients, 92% were below the age of 70 years old, 162 (81%) were hypertensive, 90(45%) were diabetic, 54 (27%) had ischemic heart diseases, and 116 (58%) had MS. The incidence of MS in the male and female patients was 50% and 67%, respectively, with a mean abdominal girth more than 94 cm in males and only 14% of the patients revealed abdominal girth measurement below 80 cm in females. We conclude that there is a high prevalence of obesity and MS in our HD patients. Such patients may be at risk of developing morbidities and may benefit from therapy such as lifestyle changes including weight reduction and increased physical activity.

    Observational studies involving hemodialysis patients suggest a U-shaped relationship between BP and mortality, but the majority of these studies followed large, heterogeneous cohorts. To examine whether age, race, and diabetes status affect the association between systolic BP (SBP; predialysis) and mortality, we studied a cohort of 16,283 incident hemodialysis patients. We constructed a series of multivariate proportional hazards models, adding age and BP to the analyses as cubic polynomial splines to model potential nonlinear relationships with mortality. Overall, low SBP associated with increased mortality, and the association was more pronounced among older patients and those with diabetes. Higher SBP associated with increased mortality among younger patients, regardless of race or diabetes status. We observed a survival advantage for black patients primarily among older patients. Diabetes associated with increased mortality mainly among older patients with low BP. In conclusion, the design of randomized clinical trials to identify optimal BP targets for patients with ESRD should take age and diabetes status into consideration.

    Homocysteine (Hcy) is a non-protein forming sulfur amino acid, synthesised from methionine (Met), whose metabolism is at the junction of two metabolic pathways: remethylation and transsulfuration. Increased Hcy serum concentration is a well established independent risk factor of cardiovascular diseases and a known feature of end stage renal disease. Hcy plasma level is influenced by folate, vitamin B6 and genetic factors. Mutation C677T in gene encoding methylenetetrahydrofolate reductase (MTHFR), an enzyme involved in Hcy remethylation has been associated with elevated Hcy in homozygous carriers (TT genotype). Several amino acids take part in metabolism of Hcy. There are abnormalities of concentration of the non essential and essential of amino acids in serum of patients treated with hemodialysis (HD). It is possible that these abnormalities of amino acids can change the Hcy metabolism. The aim of this study was the evaluation of some aspects of Hcy metabolism. We examined the MTHFR gene polymorphism and its relationship with plasma Hcy concentration. The plasma levels of total amino acids and amino acids connected with Hcy metabolism: methionine (Met), seryne (Ser), cysteine (Cyst) and tauryne (Tau) were evaluated in hemodialysis patients. The study was conducted in 71 (35 male, 36 female) patients, mean age 56.2 +/- 12.4 years. They were dialysed for a mean duration of 87.7 +/- 84.7 months (range 2-302). The control group (CG) in which Hcy and amino acids levels were examined consisted of 12 healthy subjects. Serum (EDTA) Hcy levels were measured by EIA-Hcy ELISA kit. The MTHFR gene polymorphism was evaluated by means of the polymerase chain reaction (PCR). The amino acids were measured by chromatography in amino acid analyser AAA 400. Mean concentration of Hcy was significantly higher in patients than in CG (31.1 +/- 9.1 vs 11.9 +/- 2.9 mumol/L; p < 0.01). Genotype frequencies in patients were: 42.8% for CC, 48.5% for CT and 8.7% for TT. Mean concentration of

    A chronic hemodialysis patient-known to have advanced interatrial block (IAB)-had reported symptoms suggesting arrhythmias, hence she underwent hemodialysis treatment while on the cardiac monitor. This allowed us to recognize the occurrence of paroxysmal atrial fibrillation and, in turn, disclose the first case of Bayés syndrome. Even though atrial fibrillation and IAB are very frequent in hemodialysis patients, Bayés syndrome, that comprehends both, has never been described, likely because the IAB is often overlooked and undiagnosed. This case could improve the awareness of IAB and of the Bayés syndrome in hemodialysis population. PMID:27061225

    Depression is recognized as the most common psychiatric problem in patients with end-stage renal disease. Stress negatively affects the quality of life of not only the patients on hemodialysis but also their caregivers. The objective of this study was to measure and compare the frequency of depression in these patients and their attendants, and to assess the associated risk factors in both groups. A cross-sectional study was conducted at our hemodialysis unit from June to September 2009. A total of 180 patients and 180 caregivers were enrolled and the Beck's Depression Inventory (BDI-II) questionnaire was administered. Of the 360 respondents, 201 (55.8%) were males and 264 (73.3) were married. According to the BDI scoring, 135 (75%) of the patients and 60 (33.4%) of the attendants were found to be moderately to severely depressed. Marriage (OR 1.817), low income status (OR 1.757) and unemployment (OR 4.176) correlated with increased depression grade, while gender and education level did not. Anemia was the only co-morbidity showing positive association with depression scores in the patients' group (P = 0.023). We conclude that the majority of the patients undergoing dialysis were depressed and were twice more likely to be depressed than their caregivers. In both groups, marriage and unemployment were associated with increased depressive symptoms, while household income showed negative association with depression. Gender and education level were not related to the depression scores. PMID:22982905

The serum levels of theophylline were determined by enzymatic immunoassay on two consecutive days, once on a dialysis day and again on a nondialysis day. Clearance of theophylline by hemodialysis was 119 ml/min, and the extraction efficiency was 0.56. The elimination half-life of theophylline shortened from 5.7 h to 1.6 h during hemodialysis. The dialysis rate constant (Kd) was 0.32/h, and 79 percent of the total body store of the drug was removed during a 4-h dialysis. Patients receiving theophylline who are maintained on hemodialysis should be closely monitored for bronchospasm during and after the hemodialysis procedure. Measurement of serum concentrations of theophylline should be employed to facilitate increases in dosage during hemodialysis.

  7. Dialysis disequilibrium syndrome induced by neoplastic meningitis in a patient receiving maintenance hemodialysis

    2013-01-01

    Background Dialysis disequilibrium syndrome is characterized by neurological symptoms resulting from cerebral edema, which occurs as a consequence of hemodialysis. Dialysis disequilibrium syndrome most often occurs in patients who have just started hemodialysis, during hemodialysis, or soon after hemodialysis; although it may also occur in patients who are under maintenance hemodialysis with pre-existing neurological disease. Case presentation A 70-year-old woman, who had been receiving maintenance hemodialysis for one year, was diagnosed with ovarian cancer by ascites cytological examination. Two years later, she reported severe headache and nausea during hemodialysis and was diagnosed with dialysis disequilibrium syndrome. Although brain images revealed mild hydrocephalus without any mass lesions, poorly differentiated adenocarcinoma cells were detected in her cerebrospinal fluid. These findings indicated that DDS was induced by neoplastic meningitis due to ovarian cancer metastasis. Conclusion Neoplastic meningitis should be considered and excluded in hemodialysis patients with dialysis disequilibrium syndrome and malignancy by cytological examination of the cerebrospinal fluid even if cerebral imaging shows no obvious lesions. This is the first reported case of dialysis disequilibrium syndrome induced by neoplastic meningitis in a patient receiving maintenance hemodialysis. PMID:24238645

  8. Volume-associated ambulatory BP patterns in hemodialysis patients

    Although volume excess causes hypertension whether it also affects circadian patterns of arterial pressures among hemodialysis patients remains unknown. To test the notion whether volume overload is associated with a unique BP “signature” a post-hoc analysis was performed among 145 patients participating in the dry-weight reduction in hypertensive hemodialysis patients (DRIP) randomized controlled trial. Using 400 ambulatory BP recordings over 8 weeks comprising 35,302 measurements the trended cosinor model was found to be the best descriptor of BP chronobiology. The trended cosinor model may be described as a pattern of sinusoidal oscillation around a straight line with an upward trend during the interdialytic period and which has an intercept at the postdialysis time. Augmented volume removal therapy (AVRT) reduced the intercept systolic BP and increased the rate of rise in systolic BP over the interdialytic interval but had no effect on the systolic BP fluctuation (amplitude). Thus an elevated intercept and blunted slope pattern characterizes the “volume overload BP pattern” on ambulatory BP monitoring. Similar changes were seen for diastolic BP. AVRT neither restored dipping nor was associated with a lag-phenomenon for either the wake or sleep systolic BP. Lowering of systolic BP was greater than diastolic BP such that pulse pressure was reduced. An observational cohort of 37 patients followed for 6 months confirmed these findings. Randomized trials are now needed to evaluate the clinical impact of AVRT on hard outcomes since reduction of pulse pressure with this simple expedient has the potential to improve survival in hemodialysis patients.

    Type 2 diabetes has become a pandemic disease over the past 50 years. Its incidence increases the most rapidly in the senior population, i.e. among people older than 65. In a number of countries 1/4 of the people with diabetes are now older than 65 years. Geriatrics now examines numerous differences regarding the senior patients, which often lead to somewhat different therapeutic procedures as compared to the treatment of other adult patients. This paper aims to show some different aspects of the treatment of an elderly patient with diabetes. The intensity of diabetes treatment in the elderly is mainly defined by the incidence of symptoms caused by diabetic decompensation which negatively affect quality of life and are likely to increase mortality. The treatment goals expressed by HbA1c, fasting and post-prandial glycemia, should be set individually based on age, initial HbA1c, present comorbidities and the level of frailty of an elderly patient. An effort to reduce weight regarding people at an older age is probably inappropriate and maybe even harmful, while physical activity reduces mortality and slows muscle catabolism at every age. Ideal is normal walking for 20-30 minutes a day. Except for "very fit elders" without renal insufficiency, the sulfonylurea treatment is unsuitable and perhaps even harmful. It significantly increases the incidence of different types of hypoglycemia and very likely overall mortality as well. The basis of diabetes treatment for the elderly is the effort to perform any regular exercise. In regard to medication treatment it is recommended to choose metformin or gliptin following the rule "start low, go slow", i.e. start with low medication doses and increase them at a slow pace. The main goal of the treatment is to maintain the good quality of life as long as possible, without symptoms associated with hyperglycemia with minimizing the risk of hypoglycemia development.

    Infection with hepatitis C virus (HCV) is increasing all over the world, especially among hemodialysis patients. HCV is one of the major autoantibody inducing viruses, where anti-nuclear antibodies (ANA), anti-smooth muscle antibodies (ASMA), anti-liver kidney microsome antibodies (LKM-1), and rheumatoid factor (RF) have been related to HCV. Few studies have investigated the presence of anti-extractable nuclear antigens (ENA) antibodies in chronic liver diseases, especially in chronic hepatitis C cases, but none investigated its immunostimulation role in hemodialysis units. The aim of the study was to assess the prevalence of HCV among chronic kidney disease- Stage 5 (CKD5) patients undergoing hemodialysis and the prevalence of ENA antibodies among them. Sera of 134 patients with chronic kidney disease undergoing hemodialysis, were screened for HCV antibodies and ENA antibodies profile, using ELISA and Immunoblot technique. 41 HCV-positive blood bank donors were used as controls. Sixty-four (47.7%) of 134 patients undergoing hemodialysis were infected with HCV. Thirty-three (51.6%) of 64 patients with HCV infection undergoing hemodialysis had anti-ENA antibodies: 9 (27.3%) showed anti-SSA antibodies and 22 (66.7%) had anti-SSB antibodies. The prevalence of anti-ENA antibodies was significantly higher in the patients with HCV infection, undergoing hemodialysis, compared with both control groups (hepatitis C-positive blood bank donors and hepatitis C-negative patients undergoing hemodialysis). Seventeen of 33 HCV antibodies-positive males undergoing hemodialysis had anti-ENA antibodies, compared with 16 of 31 females, indicating no sex related difference. This study emphasizes the high prevalence of HCV infection in our hemodialysis patients, comparable to that of other Middle Eastern countries, but higher than Western ones. A strong association was observed between anti-HCV positivity and hemodialysis duration, as well as anti-ENA antibody profile. However, these

    Introduction: Patients undergoing hemodialysis require direct and continuous care. Identifying the barriers to and factors facilitating hemodialysis care can improve care quality. Objectives: The aim of this study was to assess the barriers and facilitators of care for hemodialysis patients. Patients and Methods: This study was conducted as a qualitative study and it utilized content analysis approach. The study was performed in hemodialysis ward of Kowsar hospital in Semnan, in 2014. We used purposive sampling method with maximum diversity. Semi-structured interviews with open questions were used to collect data from a total of 20 participants. Results: The main topic of health care challenges was divided into two main categories, including the facilitators and barriers of hemodialysis care. The facilitators of hemodialysis care had four subcategories, including "intimate relationship", "basic knowledge", "hemodialysis skills", and "experience". The category of barriers had eight subcategories, including "shortage of nurses and heavy workload", "weak authority of the head nurse", "ignorant director of nursing", "shortage of nephrologists", "lack of vascular surgery expert", "lack of nurse’s aide and nursing assistant ", "unskilled staffs", and "interference by patients’ caregivers". Conclusion: The findings of this study showed that access to human resources and their abilities were among the factors facilitating care. However, lack of qualified medical staff at each level of care delivery was one of the barriers to hemodialysis care. Hence, it is of great importance for policy makers, managers, and program designers to recruit human resources who have the characteristics and competencies required for providing hemodialysis care.

    1981-01-01

    As one of a series of investigations of indirect self-destructive behavior, a pilot study was conducted with a group of 32 chronic hemodialysis patients for those characteristics of such behavior which had emerged as most salient in earlier studies: self-esteem, locus of control, rigidity, impulsivity, futurity, risk-taking and denial. Using an average of ratings of cooperativeness obtained from the head nurse, physician, dietician, technician, and staff nurse, the group was divided into two subgroups of more and less cooperative patients, and the demographic, medical, and psychological data from the two groups were compared. The findings suggest that the less cooperative hemodialysis patients have experienced the illness as a more severe blow to their self-concept and have failed to integrate their illness into an effective adaptive life pattern. The uncooperative patients feel less valued and less appreciated not only by their family but also by fellow patients and by hospital staff. They show significantly more anger and withdrawal than the more cooperative group and appear to have compensated for a significantly greater sense of powerlessness by the development of manipulative behaviors in relating to their medical caretakers.

    Chronic hemodialysis is associated with significant thrombophilia. Of interest, hemodialysis patients have increased carboxyhemoglobin (COHb) and exhaled carbon monoxide (CO), signs of upregulated heme oxygenase (Hmox) activity. Given that CO enhances plasmatic coagulation, we determined whether patients requiring chronic hemodialysis had an increase in endogenous CO, plasmatic hypercoagulability and decreased fibrinolytic vulnerability. Carbon monoxide was determined by noninvasive pulse oximetry measurement of COHb. Blood samples were obtained just before hemodialysis. Thrombelastographic methods to assess plasma coagulation kinetics, fibrinolytic kinetics, and formation of carboxyhemefibrinogen (COHF) were used. Hemodialysis patients (n = 45) had abnormally increased COHb concentrations of 2.2 ± 1.9%, indicative of Hmox upregulation. Coagulation and fibrinolytic parameter normal values were determined with normal individual (n = 30) plasma. Thirty-seven patients of the hemodialysis cohort had COHF formation (82.2%, [67.9%-92.0%]; mean, [95% confidence interval]), and many of this group of patients had abnormally great velocity of clot growth (73.3%, [58.1%-85.4%]) and strength (75.6%, [60.5%-87.1%]). Furthermore, over half of COHF positive patients had a hypofibrinolytic state, evidenced by an abnormally prolonged time to maximum rate of lysis (53.3%, [37.9%-68.6%]) and clot lysis time (64.4%, [48.8%-78.1%]). Carbon monoxide enhanced coagulation and diminished fibrinolytic vulnerability in hemodialysis patients. Future investigation of hemodialysis, CO-related thrombophilia is warranted.

    From 2005 to 2013, there were 15 dengue patients aged over 60 years old who were admitted to Photharam Hospital, Ratchaburi, Thailand. Ten were females and five were males. Nine had dengue fever (DF), and 6 had dengue hemorrhagic fever (DHF). A trending shift in age group towards adults has been seen during the past decades. No deaths were seen in these elderly patients with dengue disease, indicating early recognition and effective management of these dengue patients. The trend towards higher age in dengue patients is a problem of concern, which needs further elaboration.

    The study of thyroid nodules in hemodialyzed patients using ultrasonography has been described in a limited number of reports. The thyroid glands of 143 patients with end-stage renal disease on hemodialysis were examined by ultrasonography using frequency probes. Although a goiter (thyroid volume > 20 mL) was observed in only 20 patients (14%), nodular lesions of the thyroid gland were more frequent and found in 85 patients (59.4%), especially in female patients (42 patients, 72.4%). The etiology of thyroid nodular lesions was as follows: cyst in 43 (30.0%), adenomatous goiter in 14 (9.8%), adenoma in 11 (7.7%), hypoechoic lesion in 17 (11.9%), and intrathyroid calcification in 8 (5.6%). Ultrasound-guided fine-needle aspiration cytology was performed in 5 patients, but no abnormal cells were found. Compared to patients without nodules, the age was higher in patients with cysts (54 +/- 15 vs. 63 +/- 13 years; P < 0.05) and hypoechoic lesions (70 +/- 13 years; P < 0.05). The serum thyroglobulin level was higher in patients with adenomatous goiters (26 +/- 28 vs. 148 +/- 166 ng/mL; P < 0.05). The thyroid volume was greater in patients with adenomatous goiters (14.2 +/- 5.7 vs. 19.0 +/- 7.3 mL; P < 0.05) and adenomas (18.2 +/- 6.7 mL; P < 0.05). In conclusion, patients undergoing hemodialysis frequently develop thyroid abnormalities and ultrasonography is a useful imaging modality to identify these lesions.

    In 2007 the Maryland Medical Examiner noted a potential cluster of fatal vascular access hemorrhages among hemodialysis patients, many of whom died outside of a health-care setting. To examine the epidemiology of fatal vascular access hemorrhages, we conducted a retrospective case review in District of Columbia, Maryland, and Virginia from January 2000 to July 2007 and a case-control study. Records from the Medical Examiner and Centers for Medicare and Medicaid Services were reviewed, from which 88 patients were identified as fatal vascular access hemorrhage cases. To assess risk factors, a subset of 20 cases from Maryland was compared to 38 controls randomly selected among hemodialysis patients who died from non-vascular access hemorrhage causes at the same Maryland facilities. Of the 88 confirmed cases, 55% hemorrhaged from arteriovenous grafts, 24% from arteriovenous fistulas, and 21% from central venous catheters. Of 82 case-patients with known location of hemorrhage, 78% occurred at home or in a nursing home. In the case-control analysis, statistically significant risk factors included the presence of an arteriovenous graft, access-related complications within 6 months of death, and hypertension; presence of a central venous catheter was significantly protective. Psychosocial factors and anticoagulant medications were not significant risk factors. Effective strategies to control vascular access hemorrhage in the home and further delineation of warning signs are needed.

    Background 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. Methods 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. Results 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. Conclusions Healthcare professionals should recognise the factors hindering compliance from the patients' perspective while assisting them with appropriate skills in making necessary changes possible.

    Central venous occlusive disease (CVD) is a common concern among the hemodialysis patient population, with the potential to cause significant morbidity. Endovascular management of CVD, comprising percutaneous balloon angioplasty and bare-metal stenting, has been established as a safe alternative to open surgical treatment. However, these available treatments have poor long-term patency, requiring close surveillance and multiple repeat interventions. Recently, covered stents have been proposed and their efficacy assessed for the treatment of recalcitrant central venous stenosis and obstruction. Moreover, newly proposed algorithms for the surgical management of CVD warrant consideration. Here, we seek to provide an updated review of the current literature on the various treatment modalities for CVD.

    2012-01-01

    The aim of this study was to explore the perspectives of patients on hemodialysis about their experience of fluid restriction. Qualitative interviews were conducted to grasp the patients' lived experience, and from a phenomenological analysis, several categories emerged that describe patients' understanding. Three themes in particular from patients' experiences are described and discussed because of their relevance for health professionals. These include (a) fluid restriction introduces the perception of individuals to see themselves as addicts who deal with a constant inner conflict, (b) the difficulty in finding the right boundaries between common sense and scientific knowledge about fluid restriction, and (c) the role of personal motivations and willingness in pursuit of compliance. Recognizing the force of personal meaning for individuals with renal disease will support health professionals to help patients in pursuing the regime of fluid restriction. PMID:22866360

    To evaluate the effect of furosemide on cardiovascular hemodynamics in patients with end-stage renal failure, we studied ten patients undergoing hemodialysis three times a week. Arterial pressure, heart rate, and cardiac output (indocyanine green dye) were measured in triplicate; total peripheral resistance and central blood volume were calculated by standard formulas. Hemodynamics were determined at baseline and 5, 10, 15, and 30 minutes after intravenous (IV) bolus injection of furosemide 60 mg. Furosemide produced a decrease in central blood volume of -13% +/- 2.2% from pretreatment values (P less than .01) that was most pronounced five minutes after injection, together with a fall in cardiac output (from 6.76 +/- 0.59 to 6.17 +/- 0.52 L/min, P less than .10). Stroke volume decreased with a maximum fall occurring after 15 minutes (from 84 +/- 7 to 79 +/- 7 mL/min, P less than .05), and total peripheral resistance increased (from 15.8 +/- 2.1 to 17.8 +/- 2.3 units, P less than .05) after furosemide. Arterial pressure and heart rate did not change. The decrease in central blood volume reflects a shift of the total blood volume from the cardiopulmonary circulation to the periphery, suggesting dilation of the peripheral venous bed. Thus, even in patients undergoing hemodialysis, furosemide acutely decreases left ventricular preload by venous dilation and should therefore prove to be beneficial in acute volume overload.

    Purpose: Of this study was to explore the needs of hemodialysis patients and the factors that affect them. Material & Methods: The sample of the study included 141 patients undergoing hemodialysis. Data collection was performed by the method of interview using a specially designed questionnaire which served the purposes of the study. The needs were grouped into six categories. Patients were asked to answer how important was for them each of the statements in the questionnaire. Furthermore, there were collected socio-demographic characteristics, information on health status and relations with the physicians and nurses, as well as data on the incidence of the disease in their social life. Results: The results of this study showed that patients evaluated as fairly important all six categories of their needs, with similar results in both sexes. Age was found to be statistically significantly associated with ’the need for support and guidance’, ’the need to be informed’ and ’the need to meet the emotional and physical needs’, (p=0.023, p=0.012, p=0.028 respectively). Education level was found to be statistically significantly associated with all patients’ needs with the exception of ’the need to trust the medical and nursing staff’, (p=<0.05). Place of residence was statistically significantly associated with ’the need for support and guidance’, (p=0.029). Furthermore, difficulties in relations with family members was found to be statistically significantly associated with ’the need for support, the need for communication and individualization of care’, (p=0.014, p=0.040, p=0.041). After multivariate analysis, however, it was shown that the only independent factor affecting ’the need for support and guidance’, ’the need for individualized care’ and ’the need to meet the emotional and physical needs’, was if the patients reported themselves as anxious or not (p=0,024, p=0,012 and p=0,004, respectively).

    2013-09-01

    Hepatitis C virus (HCV) infection is observed in around 20% of dialysis patients and in allograft recipients and results in a significant morbidity and mortality, especially after transplantation. Its prevalence has markedly decreased in patients who are candidates for transplantation since the introduction of screening, hygiene and prevention measures, including systematic screening of blood and organ donations, use of erythropoietin, and compliance with universal hygiene rules. A liver biopsy is preferable to non-invasive biochemical and/or morphological tests of fibrosis to evaluate liver fibrosis before and even after transplantation. In HCV-infected dialyzed patients who are not candidates for renal transplantation, the indication for antiviral therapy is limited to significant fibrosis (fibrosis ≥ 2 on the METAVIR scale). Antiviral treatment should be proposed to any HCV-infected candidate for renal transplantation, whatever the baseline histopathology. The recommendation is to use standard interferon-α as monotherapy, but pegylated interferon can be used, resulting in sustained virological response, while low doses of combined ribavirin may enhance the antiviral efficacy. After transplantation, interferon-α is contra-indicated but may be used in patients for whom the benefits of antiviral treatment clearly outweigh the risks, especially that of allograft rejection. All cirrhotic patients should be screened for hepatocellular carcinoma, whose risk is enhanced by immunosuppressive regimens. Sustained suppression of necro-inflammation may result in the reversal of cirrhosis, which reduces liver-related morbidity and improves patient and allograft survival. Finally, due to the high mortality after renal transplantation, active cirrhosis must be considered to be a contraindication to kidney transplantation, but an indication to combined liver-kidney transplantation; on the contrary, inactive compensated cirrhosis may permit renal transplantation alone.

    Background Restless leg syndrome (RLS) is a sleep disorder with high prevalence among patients on hemodialysis. It has been postulated that high phosphate and high parathyroid hormone may be implicated in its pathogenesis. Standard international criteria and face-to-face interview are not always applied. Methods this was an interventional prospective study in which 19 patients (6 men, aged 48±11 years) with severe hyperparathyroidism were evaluated. RLS diagnosis and rating scale were accessed based on the International RLS Study Group pre- and post-parathyroidectomy. Patients also underwent standard polysomnography. Results At baseline, RLS was present in 10 patients (52.6%), and pain was the most reported symptom associated with the diagnosis. Patients with RLS had higher serum phosphate (p = 0.008) that remained independently associated with RLS in a logistic regression model, adjusted for hemoglobin, age and gender (HR = 7.28;CI = 1.14–46.3, p = 0.035). After parathyroidectomy, there was a reduction of serum parathyroid hormone, phosphate, calcium and alkaline phosphatase, and an increase of 25(OH)-vitamin D, and Fetuin-A. Parathyroidectomy alleviated RLS (from 52% to 21%; p = 0.04), which was accompanied by a decrease in severity scale, in association with relief of pain and pruritus. Polysomnography in these patients showed an improvement of sleep parameters as measured by sleep efficiency, sleep latency and percentage of REM sleep. Conclusion RLS is associated with high levels of phosphate in patients with severe secondary hyperparathyroidism on hemodialysis. Pain is most reported complain in these patients. Parathyroidectomy provided an opportunity to relief RLS. Whether the reduction of serum phosphorus or parathyroid hormone contributed to this improvement merits further investigation. PMID:27196740

    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 of 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.

    To characterize the nutritional status of renal failure patients and its relationship with hemodialysis adequacy measured by Kt/V, a study was carried out with a population of 44 adult patients with renal failure and mean age 51+/-15 years. Anthropometric data, such as dry weight, height, arm circumference, triceps skinfold thickness, mid-arm muscle circumference, and body mass index were assessed, and biochemical tests were conducted for urea, potassium, creatinine, serum albumin, and phosphorus levels, in addition to hemogram and quarterly urea reduction rate average (Kt/V). In order to evaluate calorie intake, a dietary questionnaire on habitual daily food ingestion was administered, taking into consideration the hemodialysis date. The patients were divided into 2 separate groups for the statistical analysis, with 50% of the patients in each group: A (Kt/V<1.2) and B (Kt/V>1.2). The data were tabulated as mean and standard deviation, with differences tested by Student's t test. The correlations between variables were established by the coefficient p of Pearson. Most of the patients (43%) were considered eutrophic, based on the BMI, and presented inadequate calorie intake, corresponding to 88.5+/-24% (30.8 kcal/kg actual weight) of the total energy required and adequate protein intake, reaching 109.9+/-40% of the recommended daily allowance (1.24 g/kg of actual weight). There was a correlation of Kt/V with anthropometric parameters such as body mass index, arm circumference, and mid-arm muscle circumference. The biochemical parameters related to dialysis adequacy were albumin, ferritin, and urea (predialysis). Well-dialyzed patients presented better levels of serum albumin. There was an influence of gender and age on correlations of the analyzed variables. Female and younger patients presented better dialysis adequacy. The dialysis adequacy was related to the nutritional status and influenced by the protein intake and body composition. Gender and age had an

    Coronary artery calcification (CAC) leads to a significant increase in cardiovascular morbidity and mortality in hemodialysis (HD) patients. Metabolic acidosis, which is common in HD patients, promotes bone resorption in human and animals as a result of buffer function of bone, and calcium and phosphate elute from bone into blood stream. However, the effect of acidosis on CAC in HD patients has never been precisely investigated. This is a cross-sectional observational study performed in a single center. One hundred and seven prevalent HD patients (35 women and 72 men) underwent electron-beam computed tomography (EBCT) to evaluate CAC score (CACS), and then we evaluated associated factors of CACS with clinical and laboratory parameters including pre-HD pH and bicarbonate levels. Pre-HD pH and bicarbonate levels were 7.35 ± 0.04, and 17.6 ± 1.8 mmol/L, respectively. The pre-HD pH had no significant correlation to CACS (r = -0.025, P = 0.81). CACS was significantly negatively correlated with pre-HD bicarbonate levels (r = -0.329, P = 0.0009) and serum albumin levels (r = -0.298, P = 0.0467), while it was positively correlated with age (r = 0.319, P = 0.0008) and HD duration (r = 0.385, P = 0.0004). Serum levels of calcium, phosphorus, intact parathyroid hormone, and use of phosphorus binders were not related to CACS. Multivariate analysis indicated that plasma pre-HD bicarbonate level was independently associated with CACS. The present study showed that blood levels of pre-HD bicarbonate were significantly associated with CAC in HD patients. Further studies are needed to confirm these results and to determine whether correction of metabolic acidosis prevents the development of CAC, one of the features of accelerated atherosclerosis in HD patients.

    The prevalence and incidence of heart failure (HF) is increasing, especially in the elderly population, and is becoming a major geriatric problem. Elderly patients with HF usually show etiopathogenic, epidemiological, and even clinical characteristics significantly different from those present in younger patients. Their treatment, however, derives from clinical trials performed with only a few elderly subjects. Moreover, beyond the cardiovascular disease itself, it is essential to evaluate the patient as a whole, given the interrelationship between HF and the characteristic geriatric syndromes of the elderly patient. This review examines the peculiarities in the most prevalent "real world" HF patient.

    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.

    Peripheral artery disease (PAD) and low heart rate variability (HRV) are highly prevalent in hemodialysis patients, and both are associated with increased cardiovascular morbidity and mortality. This study aims to examine the suggested relationship between PAD and HRV, and the relationship of parameters before and after hemodialysis. This study enrolled 161 maintenance hemodialysis patients. PAD was defined as ABI < 0.9 in either leg. HRV was performed to assess changes before and after hemodialysis. The change in HRV (△HRV) was defined as post-hemodialysis HRV minus pre-hemodialysis HRV. Patients’ clinical parameters were collected from the dialysis records. All HRV parameters except high frequency (HF) % were lower in patients with PAD than patients without PAD, though not achieving significant level. In patients without PAD, HF (P = 0.013), low frequency (LF) % (P = 0.028) and LF/HF (P = 0.034) were significantly elevated after hemodialysis, whereas no significant HRV parameters change was noted in patients with PAD. Serum intact parathyroid hormone was independently associated with △HF (β = -0.970, P = 0.032) and △LF% (β = -12.609, P = 0.049). Uric acid level (β = -0.154, P = 0.027) was negatively associated with △LF/HF in patients without PAD. Our results demonstrated that some of the HRV parameters were significantly increased after hemodialysis in patients without PAD, but not in patients with PAD, reflecting a state of impaired sympatho-vagal equilibrium. Severity of secondary hyperparathyroidism and hyperuricemia contributed to lesser HRV parameters increase after hemodialysis in patients without PAD. PMID:26237669

    Background Dabigatran and rivaroxaban are new oral anticoagulants that are eliminated through the kidneys. Their use in dialysis patients is discouraged because these drugs can bio-accumulate to precipitate inadvertent bleeding. We wanted to determine if prescription of dabigatran or rivaroxaban was occurring in the dialysis population and if these practices were safe. Methods and Results Prevalence plots were used to describe the point prevalence (monthly) of dabigatran and rivaroxaban use among 29,977 hemodialysis patients with atrial fibrillation (AF). Poisson regression compared the rate of bleeding, stroke, and arterial embolism in patients who started dabigatran, rivaroxaban, or warfarin. The first record of dabigatran prescription among hemodialysis patients occurred 45 days after the drug became available in the US. Since then, dabigatran and rivaroxaban use in the AF-ESRD population has steadily risen where 5.9% of anti-coagulated dialysis patients are started on dabigatrian or rivaroxaban. In covariate adjusted Poisson regression, dabigatran (RR=1.48; 95% CI 1.21-1.81, p=0.0001) and rivaroxaban (RR=1.38; 95% CI 1.03-1.83, p=0.04) associated with a higher risk of hospitalization or death from bleeding when compared to warfarin. The risk of hemorrhagic death was even larger with dabigatran (RR=1.78; 95% CI 1.18-2.68, p=0.006) and rivaroxaban (RR=1.71; 95% CI 0.94-3.12, p=0.07) relative to warfarin. There were too few events in the study to detect meaningful differences in stroke and arterial embolism between the drug groups. Conclusions More dialysis patients are being started on dabigatran and rivaroxaban, even when their use is contraindicated and there are no studies to support the benefits outweigh the risks of these drugs in ESRD.

    This qualitative study describes the temporal patterns of fatigue found as part of a larger study designed to elicit a description of the experience and self-management of fatigue for patients on hemodialysis. Two patterns of fatigue were identified. The first pattern, continuous fatigue, was characterized by participants who experienced fatigue at all times, which was their normal, baseline feeling. Within this group, two subgroups were identified. The second pattern of fatigue, post-dialysis fatigue only, was characterized by participants who experienced fatigue only after their hemodialysis session. This study is unique because it expands our knowledge about hemodialysis and fatigue by describing the patterns that fatigue follows over time from one hemodialysis session to the next. Insight into these phenomena could help ameliorate fatigue and allow nurses to tailor interventions for patients on hemodialysis. PMID:27254968

    The study aimed to estimate the incidence of HCV seroconversion in hemodialysis patients in the Brazilian Unified National Health System (SUS). This was a prospective, non-concurrent study using patients' data identified by deterministic and probabilistic record linkage in the SUS information system. The study included 47,079 patients started on hemodialysis between January 1, 2000, and December 31, 2003, followed until seroconversion or conclusion of the study in 2004. Three percent of hemodialysis patients HCV-seroconverted (1.7 per 100 patient-years). Increased risk of HCV seroconversion was associated with age, glomerulonephritis, geographic region, HIV-positivity, and dialysis service. The observed HCV seroconversion rate was similar to that in developed countries, highlighting evidence of transmission among hemodialysis patients. PMID:27509552

    Although several previous studies have been published on the effects of dipeptidase-4 (DPP-4) inhibitors in diabetic hemodialysis (HD) patients, the findings have yet to be reviewed comprehensively. Eyesight failure caused by diabetic retinopathy and aging-related dementia make multiple daily insulin injections difficult for HD patients. Therefore, we reviewed the effects of DPP-4 inhibitors with a focus on oral antidiabetic drugs as a new treatment strategy in HD patients with diabetes. The following 7 DPP-4 inhibitors are available worldwide: sitagliptin, vildagliptin, alogliptin, linagliptin, teneligliptin, anagliptin, and saxagliptin. All of these are administered once daily with dose adjustments in HD patients. Four types of oral antidiabetic drugs can be administered for combination oral therapy with DPP-4 inhibitors, including sulfonylureas, meglitinide, thiazolidinediones, and alpha-glucosidase inhibitor. Nine studies examined the antidiabetic effects in HD patients. Treatments decreased hemoglobin A1c and glycated albumin levels by 0.3% to 1.3% and 1.7% to 4.9%, respectively. The efficacy of DPP-4 inhibitor treatment is high among HD patients, and no patients exhibited significant severe adverse effects such as hypoglycemia and liver dysfunction. DPP-4 inhibitors are key drugs in new treatment strategies for HD patients with diabetes and with limited choices for diabetes treatment.

    Purpose: Recently, performance of cardiac surgery in hemodialysis patients has increased, but the mortality rate is high. Methods: We retrospectively examined the early and long-term outcomes in 128 dialysis patients who underwent cardiac surgery with or without carperitide infusion and were followed for 2 years. Sixty-three patients received carperitide infusion during surgery and 65 patients did not. Results: The hospital mortality rate was 1.6% in the carperitide group and 12.3% in the non-carperitide group, being significantly lower in the carperitide group. The 2-year actuarial survival rate was 90.5% ± 3.7% in the carperitide group, and 76.9% ± 5.2% in the non-carperitide group, while the major adverse cardiovascular and cerebrovascular events (MACCE)-free rate at 2 years postoperatively was 90.5% ± 3.7% in the carperitide group and 67.7% ± 5.8% in the non-carperitide group. Conclusions: These findings suggest that carperitide improves the early postoperative outcome in dialysis patients undergoing cardiac surgery, as has already been demonstrated in non-dialysis patients. An early postoperative cardioprotective effect of carperitide and improvement of renal function in oliguric patients might have contributed to this outcome. However, this was a retrospective study, so a prospective investigation is required to demonstrate the mechanisms involved. In addition, further evaluation of the long-term results would be desirable. PMID:27025780

    Oral manifestations of severe secondary hyperparathyroidism include maxillary and mandibular deformities, brown tumors, dental abnormalities, and metastatic calcification of soft tissues. We report on a chronic hemodialysis (HD) woman with severe, uncontrolled secondary hyperparathyroidism and a painful, nontender mass in the floor of her mouth. The most likely clinical diagnosis was a bone tumoral lesion of the oral cavity, secondary to renal osteodystrophy. Unexpectedly, pathological examination showed characteristic features of ossifying fibroma (OF) of the jaw, a rare, benign fibroosseous lesion characterized by the replacement of normal bone by collagen and fibroblasts containing varying amounts of mineralized substance. The occurrence of an OF in chronic HD patients is exceptional. Differential diagnosis must be made with bone tumoral lesions secondary to renal osteodystrophy. Surgical removal is the treatment of choice. The pathogenesis of OF in the setting of secondary hyperparathyroidism remains unknown. Parathyroidectomy may not be necessary to avoid OF recurrence after surgical removal. PMID:27800197

    Antibody reactivities to hepatitis C virus (HCV) antigens and to synthetic peptides derived from different parts of the HCV genome (core, NS4, and NS5) were evaluated in HCV-infected hemodialysis patients. In the RIBA 3 assay, NS5 was significantly less recognizable by sera of hemodialysis patients compared to other HCV-infected subjects. Among hemodialysis patients, those coinfected with hepatitis B virus (HBV) (positive for hepatitis B surface antigen [HBsAg+]) showed a reduction in reactivity to C33 and C100. Sera of only 23% of the hemodialysis patients (37 of 161) reacted with more than three of eight peptides tested, significantly fewer than the 60% (12 of 20) of the sera of other HCV-infected patients tested (P = 0.001). This immunosuppression was also manifested by a reduced frequency of recognition of additional peptides on follow-up. An even more reduced reactivity was observed among the HBV-coinfected patients (HBsAg+). The low-responder hemodialysis patients were not infected with any particular genotype of HCV, and the same HCV genotypes observed in the whole group of hemodialysis patients (1a, 1b, 2a, and 3a) were found circulating in the low-responder group. Even in this low-responder population, the good performance of two peptides (peptide 716, corresponding to a portion of the core, and peptide 59, corresponding to a portion of NS4) corroborates the immunodominance of the conserved epitopes within these peptides.

    Spalled particles of silicone were observed in the livers of patients with chronic renal failure treated by hemodialysis. The refractile particles of silicone were associated with various degrees of hepatic inflammation and fibrosis, and granulomatous hepatitis was evident in nine cases. Retrospective examination revealed the material in 18 of 38 liver-biopsy samples from patients on hemodialysis who had clinical hepatic dysfunction. Of 31 autopsies of patients who had undergone hemodialysis, 22 revealed silicone in the liver, and silicone was also present in the spleen in all cases and in the marrow, lungs, and nodes in some. Giant cells containing silicone were also observed in these organs. Silicone was present in patients who had undergone hemodialysis for six weeks to 84 months (mean, 24 months). The identity of the material was confirmed by atomic absorption and by electron microprobe analysis. The silicone was traced to a segment of silicone tubing located in the roller pump of the dialysis machine.

    BACKGROUND: Cardiac biomarkers are often elevated in dialysis patients showing the presence of left ventricular dysfunction. The aim of the study is to establish the plasma levels of high-sensitivity cardiac troponin T (hs TnT), precursor of B-natriuretic peptide (NT-proBNP) and high sensitivity C-reactive protein (hs CRP) and their relation to the presence of left ventricular hypertrophy (LVH) in patients undergoing hemodialysis without signs of acute coronary syndrome or heart failure. MATERIAL AND METHODS: We studied 48 patients - 26 men and 22 women. Pre and postdialysis levels of hs cTnT, NT-proBNP and hs CRP were measured at week interim procedure. Patients were divided in two groups according to the presence of echocardiographic evidence of LVH - gr A - 40 patients (with LVH), and gr B - 8 patients (without LVH). RESULTS: In the whole group of patients was found elevated predialysis levels of all three biomarkers with significant increase (p < 0.05) after dialysis with low-flux dialyzers. Predialysis values of NT-proBNP show moderate positive correlation with hs cTnT (r = 0.47) and weaker with hs CRP (r = 0.163). Such dependence is observed in postdialysis values of these biomarkers. There is a strong positive correlation between the pre and postdialysis levels: for hs cTnT (r = 0.966), for NT-proBNP (r = 0.918) and for hs CRP (r = 0.859). It was found a significant difference in the mean values of hs cTnT in gr. A and gr. B (0.07 ± 0.01 versus 0.03 ± 0.01 ng/mL, p < 0.05) and NT-proBNP (15,605.8 ± 2,072.5 versus 2,745.5 ± 533.55 pg/mL, p < 0.05). Not find a significant difference in hs CRP in both groups. CONCLUSIONS: The results indicate the relationship of the studied cardiac biomarkers with LVH in asymptomatic patients undergoing hemodialysis treatment. PMID:27275331

    Suicide risk (SR) has been associated to several factors; one of them is the presence of psychiatric disorders. This study has the objective of investigating the relationship between the risk factors for suicidal behavior in patient bearers of chronic renal illness who are undertaking hemodialysis treatment. Sixty-nine undertook a short, structured diagnostic interview. The prevalence of some psychiatric disorders showed itself greater in the sample than that in the population in general. A significant positive correlation was found between SR, major depressive episode, and agoraphobia without panic disorder. The religiosity of the patient was also evaluated as an influencing factor of SR. Nonreligious patients had 8 times more chance to have SR compared to religious patients. However, the referred effect only occurred in nondepressed religious patients. The latter indicated that religiosity had its effect annulled in depressed patients. This study shows the importance of measures of intervention in mental health, mainly in relation to prevention and treatment of major depressive episode with a view to reducing SR. PMID:21193182

    The recent emphasis on assessment of the psychological status, availability of newer and better methods of interpreting the anthropometric measurements of renal patients on dialysis therapy prompted the authors to develop the "Holistic Health Assessment Tool for dialysis patients (HHAT-D)." A total of 30 subjects (25-65 years), enrolled from dialysis centers in Mumbai were administered the HHAT-D tool to assess anthropometric, biochemical, functional, and psychological status (knowledge, needs, that coping strategies) along with dietary intake. The results showed that majority of the patients (73.3%) were mild to moderately malnourished. A highly significant negative correlation of anthropometric measurements (BMI, lean body mass, mid arm circumference, arm muscle area, bicep skin fold thickness, % usual body weight, and % standard body weight) with the HHAT-D scores (P<0.01) confirmed the validity of the tool in assessing the degree of malnutrition. The poor health status of the patients was further confirmed by the average (40%) to poor (36.6%) flexibility status and poor dietary nutrient intake. Moderate (36.6%) to high (60%) coping effectiveness was recorded in the patients as assessed using the "coping effectiveness inventory." A high degree of interitem correlation (Cronbach's coefficient alpha-test value 0.836) also proved the reliability of the HHAT-D tool. Thus, the HHAT-D was found to be a specific and reliable tool for assessment of holistic health status of patients on maintenance hemodialysis to improve quality of life and facilitate faster recovery.

    Depression and sleep disorders are more frequent in patients on maintenance hemodialysis (HD) than the general population, and are associated with reduced quality of life and increased mortality risk. The purpose of this study was to assess the prevalence of depression, sleep apnea, insomnia in patients on HD as well as depression in their primary caregiver and to correlate these with the demographic profile. A cross-sectional study was conducted among 69 patients on maintenance HD for more than 3 months. There was high p revalence of depression (47.8%), insomnia (60.9%), increased risk of sleep apnea (24.6%) and depression in caregiver (31.9%). Depression was significantly more in patients with low monthly income (P=0.03), those on dialysis for more than 1 year (P=0.001) and the unemployed (P=0.009). High-risk patients for sleep apnea tended to be males with low monthly income (P=0.02). Insomnia was significantly higher in patients who were on dialysis for more than 1 year (P=0.003).

    Erectile dysfunction (ED) is defined as the inability to attain or maintain an erection sufficient for satisfactory sexual performance. This cross-sectional study was conducted on patients on hemodialysis (HD) in Shiraz, Iran, using the International Index of Erectile Dysfunction questionnaire for determination of the frequency and severity of ED in these patients. We used the Chi-square, Mann-Whitney, Kruskal-Wallis and Pearson's correlation coefficient tests for statis-tical analysis. A total of 73 patients were enrolled into this study. The mean score of ED was 10.3 ± 6.3 (total score 25). The prevalence of ED of various degrees was 87.7%. There was a significant correlation between different degrees of ED and age (P = 0.002); it was significantly higher in patients older than 50 years (P = 0.005). Also, ED was more common in patients whose Kt/V was <1.2 (P = 0.04). Our study suggests that ED is a major health concern in patients on HD. Improvement of ED may improve their quality of life. Our results can give the basic data for future research in this field. PMID:21422619

    Serum albumin had been noted to be a predictor of mortality in hemodialysis (HD) patients. Normalized protein catabolic rate (nPCR) less than 0.8 or greater than 1.4 g/kg/d was also associated with greater mortality. There was no previous study to show the effectiveness of combination of serum albumin and nPCR to predict the mortality in chronic HD patients. Eight hundred and sixty-six patients were divided into 4 groups according to their nPCR and serum albumin levels. Biochemical, and hematological parameters were recorded. The associations between groups, variables mentioned above and mortality were analyzed. Multivariate Cox regression analysis showed that age, diabetes mellitus, fistula as blood access, nPCR <1.2 g/kg/day combined with albumin <4 (Group A), nPCR ≧ 1.2 g/kg/day combined with albumin <4 g/dL (Group B) (nPCR ≧ 1.2 g/kg/day combined with Albumin ≧ 4 g/dL as reference group), non-anuria, hemoglobin, creatinine, and log (high sensitivity C reactive protein) were correlated with 36 months mortality. Group A and group B patients had higher 36 months cardiovascular (CV) and infection related mortality rates as compared with group D patients. In conclusion, Group A and Group B patients had significantly higher rate of all-cause, CV and infection related mortality. PMID:27752119

    Background and objectives: No studies have evaluated the relationship among spirituality, social support, and survival in patients with ESRD. This study assessed whether spirituality was an independent predictor of survival in dialysis patients with ESRD after controlling for age, diabetes, albumin, and social support. Design, setting, participants, & measurements: A total of 166 patients who had ESRD and were treated with hemodialysis completed questionnaires on psychosocial variables, quality of life, and religious and spiritual beliefs. The religious variables were categorized into three scores on a 0 to 20 scale (low to high levels): Spirituality, religious involvement, and religion as coping. Social support was assessed using the Multidimensional Scale for Perceived Social Support. Analyses were also performed including and excluding patients with HIV infection. Religious variables were categorized on the basis of means, medians, and tertiles. Results: In analyses that used religious variables, only the responses on the spirituality scale split at the mean were associated with survival. The association of other religious variables with survival did not reach significance. Social support correlated with spirituality, religion as coping, and religious involvement measures. Only social support and age were associated with survival when controlling for diabetes, albumin concentration, HIV infection, and spirituality. Conclusions: These data suggest that the effects of spirituality may be mediated by social support. Larger, multicenter, prospective studies that use well-validated tools to measure religiosity and spirituality are needed to determine whether there is an independent association of spirituality variables with survival in patients with ESRD.

    Studies related to psychological aspects of dialysis patients show that depression and anxiety are the most common characteristics. The aim of our study was to analyze the personality profile in patients on chronic maintenance dialysis and to evaluate more specifically the level of depression. The total number of patients was 68 (30 females and 38 males), with mean age 62.3 and 56.5 for females and males respectively. Mean duration of dialysis was 6.73 years for females and 6.68 years for men (the period varied from 0.5 to 18 years). For the evaluation of psychological characteristics, we used two psychometric instruments: Minnesota Multiphase Personality Inventory (MMPI- 201) and Beck Depression Inventory. The obtained results confirmed the presence of depression in patients treated with hemodialysis. The level of depression is variable (minimal is present in 21.43%; mild in 35.71%; moderate in 17.85% and severe in 14.28% of patients). The depression is significantly positively correlated with age (p<0.05) as well as with educational level, and negatively with the duration of dialysis. Specific characteristics of personality obtained with MMPI are hypersensitivity, depressive mood, and withdrawal from friends and relatives. More specific emotional traits are the accentuated anxiety, low level of hostility, but very high passive aggression which destroys their social communications. Some response measures for depression such as relaxation training, psychological support, music therapy, or peripheral biofeedback are recommended. PMID:23335381

    Background Hemodialysis patients are at risk for deficiency of essential trace elements and excess of toxic trace elements, both of which can affect health. We conducted a systematic review to summarize existing literature on trace element status in hemodialysis patients. Methods All studies which reported relevant data for chronic hemodialysis patients and a healthy control population were eligible, regardless of language or publication status. We included studies which measured at least one of the following elements in whole blood, serum, or plasma: antimony, arsenic, boron, cadmium, chromium, cobalt, copper, fluorine, iodine, lead, manganese, mercury, molybdenum, nickel, selenium, tellurium, thallium, vanadium, and zinc. We calculated differences between hemodialysis patients and controls using the differences in mean trace element level, divided by the pooled standard deviation. Results We identified 128 eligible studies. Available data suggested that levels of cadmium, chromium, copper, lead, and vanadium were higher and that levels of selenium, zinc and manganese were lower in hemodialysis patients, compared with controls. Pooled standard mean differences exceeded 0.8 standard deviation units (a large difference) higher than controls for cadmium, chromium, vanadium, and lower than controls for selenium, zinc, and manganese. No studies reported data on antimony, iodine, tellurium, and thallium concentrations. Conclusion Average blood levels of biologically important trace elements were substantially different in hemodialysis patients, compared with healthy controls. Since both deficiency and excess of trace elements are potentially harmful yet amenable to therapy, the hypothesis that trace element status influences the risk of adverse clinical outcomes is worthy of investigation.

    Atherosclerosis is a major cause of mortality and morbidity among hemodialysis patients, but whether it is more severe in hemodialysis patients than in cardiovascular disease patients without chronic kidney disease is unclear. We examined 46 autopsy patients who had undergone hemodialysis, and age and sex-matched 46 patients with cardiovascular disease and an eGFR of >60 mL/min/1.73 m(2). There was no difference in the prevalence of diabetes or hypertension between the groups. We divided the aorta into four segments: A, ascending artery to arch; B, descending artery to diaphragm; C, suprarenal; and D, infrarenal. We used the classification of the American Heart Association to evaluate atherosclerosis progression. Distribution was scored by the extent to which each segment was damaged: 0, none; 1, less than 1/3; 2, more than 1/3 to less than 2/3; 3, more than 2/3. Histological examination revealed that the progression score (P < 0.05) and distribution score (P<0.005) were more severe in the hemodialysis group, especially in segment A. Regression analysis showed that atherosclerosis of segment A was related to age, gender, dyslipidemia, smoking, hemodialysis therapy, and hemodialysis duration. In hemodialysis patients, atherosclerotic changes in the aorta were more severe than in cardiovascular disease patients with an eGFR of >60 mL/min/1.73 m(2). Aortic atherosclerosis was aggravated by traditional and chronic kidney disease-related risk factors.

    Background and objectives Intradialytic hypoxemia has been recognized for decades, but its associations with outcomes have not yet been assessed in a large patient cohort. Design, setting, participants, & measurements Our retrospective cohort study was conducted between January of 2012 and January of 2015. We recorded blood oxygen saturation every minute during hemodialysis in patients with arteriovenous access. A 6-month baseline period with at least 10 treatments with oxygen saturation measurements preceded a 12-month follow-up. Patients were stratified by the presence or absence of prolonged intradialytic hypoxemia defined as oxygen saturation <90% for at least one third of the treatment time. Demographic, laboratory, and treatment data and hospitalization and mortality rates were compared between the groups. Multivariate Cox regression analysis was used to assess baseline predictors of all-cause mortality during follow-up. Results In total, 100 (10%) of 983 patients had prolonged intradialytic hypoxemia. These patients were older (+3.6 years; 95% confidence interval, 0.8 to 6.3), had longer dialysis vintage (+1.2 years; 95% confidence interval, 0.3 to 2.1), and had higher prevalence of congestive heart failure (+10.8%; 95% confidence interval, 1.6 to 20.7) and chronic obstructive pulmonary disease (+13%; 95% confidence interval, 5 to 21.2). They also resembled an inflammatory phenotype, with lower serum albumin levels (−0.1 g/dl; 95% confidence interval, −0.2 to 0) and higher neutrophil-to-lymphocyte ratios (+1; 95% confidence interval, 0.5 to 1.6). They had lower hemoglobin levels (−0.2 g/dl; 95% confidence interval, −0.4 to 0) and required more erythropoietin (+1374 U per hemodialysis treatment; 95% confidence interval, 343 to 2405). During follow-up, all-cause hospitalization (1113 hospitalizations; univariate hazard ratio, 1.46; 95% confidence interval, 1.22 to 1.73) and mortality (89 deaths; adjusted hazard ratio, 1.98; 95% confidence interval, 1

To study this, we measured dolutegravir plasma concentrations in samples of blood entering and leaving the dialyzer and of the resulting dialysate from 5 HIV-infected patients with end-stage renal disease. The median dolutegravir hemodialysis extraction ratio was 7%. The dolutegravir concentrations after the dialysis session remained far above the protein-binding-adjusted inhibitory concentration. Our results show minimal dolutegravir removal by hemodialysis, with no specific dolutegravir dosage adjustments required in this setting.

    Hemodialysis (HD), despite being the most common treatment modality for endstage renal disease (ESRD), still carries a mortality rate higher than 20-50%/year resulting from various comorbidities. The aim of this study was to measure the plasma level of pentraxin-3 (PTX-3) in patients on maintenance HD and to assess its relationships to comorbidities such as malnutrition and associated comorbid diseases. This case-control study included 50 HD patients, 30 ESRD patients, and 30 healthy controls. HD patients were classified into different subgroups according to the Davies comorbidity index and malnutrition score. Plasma PTX-3 was analyzed by a sandwich ELISA technique. Plasma level of PTX-3 reached its highest levels in HD patients followed by ESRD patients as compared to healthy controls. Moreover, within the different subgroups, the highest levels and the highest odd ratio of PTX-3 were detected in the subgroups having the highest Davies comorbidity index or the highest malnutrition score as compared to the other subgroups. At a cutoff of 0.6 ng/mL, PTX-3 was able to discriminate HD patients with low Davies comorbidity index from those with both medium and high Davies comorbidity index with a diagnostic sensitivity of 92.5% and a diagnostic specificity of 70.0%. Meanwhile, the best cutoff of plasma PTX-3 for discriminating patients with mild malnutrition from severe and moderate malnutrition was 0.6 ng/mL with a diagnostic sensitivity of 90.9% and a diagnostic specificity of 41.2%. In conclusion, PTX-3 appears to be a clinically useful marker for the early identification of patients with renal failure on maintenance HD who are at substantially increased risk of morbidity. These patients may require care and aggressive follow-up in more specialized units and an early referral to a renal transplant center.

    Intravenous vitamin D is standard therapy for secondary hyperparathyroidism in hemodialysis (HD) patients. In for-profit dialysis clinics, mortality was higher for patients on calcitriol compared to paricalcitol. Doxercalciferol, a second vitamin D2 analog, is currently available. We assessed mortality associated with each vitamin D analog and with lack of vitamin D therapy in patients who began HD at Dialysis Clinic Inc. (DCI), a not-for-profit dialysis provider. During the 1999-2004 study period we studied 7731 patients (calcitriol: n=3212; paricalcitol: n=2087; doxercalciferol: n=2432). Median follow-up was 37 weeks. Mortality rates (deaths/100 patient-years) were identical in patients on doxercalciferol (15.4, 95% confidence interval (13.6-17.1)) and paricalcitol (15.3 (13.6-16.9)) and higher in patients on calcitriol (19.6 (18.2-21.1)) (P<0.0001). In all models mortality was similar for paricalcitol versus doxercalciferol (hazard ratios=1.0). In unadjusted models, mortality was lower in patients on doxercalciferol (0.80 (0.66, 0.96)) and paricalcitol (0.79 (0.68, 0.92)) versus calcitriol (P<0.05). In adjusted models, this difference was not statistically significant. In all models mortality was higher for patients who did not receive vitamin D versus those who did (1.2 (1.1-1.3)). Mortality in doxercalciferol- and paricalcitol-treated patients was virtually identical. Differences in survival between vitamin D2 and D3 may be smaller than previously reported.

    BACKGROUND Respiratory system disorders are one of the most prevalent complications in end-stage renal disease patients on hemodialysis. However, the pathogenesis of impaired pulmonary functions has not been completely elucidated in these patients. We designed a study to investigate acute effects of hemodialysis treatment on spirometry parameters, focusing on the relationship between pulmonary function and fluid status in hemodialysis patients. MATERIAL AND METHODS We enrolled 54 hemodialysis patients in this study. Multifrequency bioimpedance analysis (BIA) was used to assess fluid status before and 30 min after the midweek of hemodialysis (HD). Overhydration (OH)/extracellular water (ECW)% ratio was used as an indicator of fluid status. Fluid overload was defined as OH/ECW ≥7%. Spirometry was performed before and after hemodialysis. RESULTS Forced vital capacity (FVC), FVC%, and forced expiratory volume in the first second (FEV1) levels were significantly increased after hemodialysis. FVC, FVC%, FEV1, FEV1%, mean forced expiratory flow between 25% and 75% of the FVC (FEF25-75), FEF25-75%, peak expiratory flow rate (PEFR), and PEFR% were significantly lower in patients with fluid overload than in those without. OH/ECW ratio was negatively correlated with FVC, FVC%, FEV1, FEV1%, FEF25-75, FEF25-75%, PEFR, and PEFR%. Stepwise multiple regression analysis revealed that male sex and increased ultrafiltration volume were independently associated with higher FVC, whereas increased age and OH/ECW ratio were independently associated with lower FVC. CONCLUSIONS Fluid overload is closely associated with restrictive and obstructive respiratory abnormalities in HD patients. In addition, hemodialysis has a beneficial effect on pulmonary function tests, which may be due to reduction of volume overload. PMID:27497672

    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. PMID:23411788

    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.

    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.

    Data from the Canadian Organ Replacement Registry (CORR) and the Dialysis Outcomes and Practice Patterns Study (DOPPS) were used to determine whether practice patterns have changed in Canada since the introduction of the Canadian Society of Nephrology (CSN) Guidelines in 1999. DOPPS data were then used to calculate the impact of not meeting the proposed guideline targets and to estimate the potential life years gained if all Canadian hemodialysis patients achieved guideline targets. For dialysis dose and hemoglobin targets, Canadian facility performance has significantly improved over time. The vascular access use patterns show trends toward a worse pattern with increased catheter use. A calculation of the percentage of attributable risk suggests that 49% of deaths could possibly be averted if all patients currently outside the guidelines achieved them over the next five years. This corresponds to a decrease in the annual death rate from 18 to 10.1 per hundred patient years. These data support the need for improved adherence to guidelines. If Canadian caregivers were to optimize practice patterns, patient outcomes could be improved. PMID:17691708

    AIM To investigate awareness and attitudes about preventive dental visits among dialysis patients; to clarify the barriers to visiting the dentist. METHODS Subjects included 141 dentate outpatients receiving hemodialysis treatment at two facilities, one with a dental department and the other without a dental department. We used a structured questionnaire to interview participants about their awareness of oral health management issues for dialysis patients, perceived oral symptoms and attitudes about dental visits. Bivariate analysis using the χ2 test was conducted to determine associations between study variables and regular dental check-ups. Binominal logistic regression analysis was used to determine factors associated with regular dental check-ups. RESULTS There were no significant differences in patient demographics between the two participating facilities, including attitudes about dental visits. Therefore, we included all patients in the following analyses. Few patients (4.3%) had been referred to a dentist by a medical doctor or nurse. Although 80.9% of subjects had a primary dentist, only 34.0% of subjects received regular dental check-ups. The most common reasons cited for not seeking dental care were that visits are burdensome and a lack of perceived need. Patients with gum swelling or bleeding were much more likely to be in the group of those not receiving routine dental check-ups (χ2 test, P < 0.01). Logistic regression analysis demonstrated that receiving dental check-ups was associated with awareness that oral health management is more important for dialysis patients than for others and with having a primary dentist (P < 0.05). CONCLUSION Dialysis patients should be educated about the importance of preventive dental care. Medical providers are expected to participate in promoting dental visits among dialysis patients.

Although 80.9% of subjects had a primary dentist, only 34.0% of subjects received regular dental check-ups. The most common reasons cited for not seeking dental care were that visits are burdensome and a lack of perceived need. Patients with gum swelling or bleeding were much more likely to be in the group of those not receiving routine dental check-ups (χ2 test, P < 0.01). Logistic regression analysis demonstrated that receiving dental check-ups was associated with awareness that oral health management is more important for dialysis patients than for others and with having a primary dentist (P < 0.05). CONCLUSION Dialysis patients should be educated about the importance of preventive dental care. Medical providers are expected to participate in promoting dental visits among dialysis patients.

    Homocysteine is an independent risk factor for cardiovascular disease in the general population. In addition, it plays a main role in the development of atherogenesis and thrombosis, particularly in end-stage renal disease patients. Therefore, hemodialysis patients are under the burden of homocysteine toxic effects, present in nearly 90% of dialysis patients. Our group found that folic acid is an efficient therapeutic approach to decrease homocysteine levels, and the addition of intravenous methylcobalamin potentiates this effect; however, methylcobalamin alone was unsuccessful to normalize homocysteine levels. With time a group of patients required a higher dose of folic acid to reduce hyperhomocysteinemia. Patients homozygous and, to a lesser extent heterozygous, to the C677T thermolabile variant of methylenetetrahydrofolate reductase (MTHFR) presented a reduced catalytic activity and required a higher folic acid dose. Vascular-access thrombotic events were similar in all patients according to the variants of the enzyme, suggesting that treating hyperhomocysteinemia was the key to lower the risk of thromboses. Noteworthy, hypohomocysteinemia, generally acompanying malnourishment, is associated to higher mortality. Albeit hyper-homocysteinemia is considered a vascular risk factor in renal failure patients, it has not yet been established in this population if its correction is associated with a decrease in the rate of vascular disease and thrombosis. However, given the mentioned evidence about the low risk and good tolerance of vitamin therapy, we believe it useful to know folate, cobalamin and homocysteine blood levels in chronic renal patients and start a prompt treatment, which may proof adequate to maintain homocysteine levels of 10 +/- 5 micromol/l.

    Cooling the dialysate below 36.5 degrees C is an important factor that contributes to hemodynamic stability in patients during hemodialysis (HD). In this study, the effect of dialysate temperature on hemodynamic stability, patients' perception of dialysis discomfort and post dialysis fatigue were assessed in a group of patients on HD. A total of 50 patients, all of whom were on 3-times-per-week dialysis regimen, were studied. Patients were assessed during six dialysis sessions; in three sessions, the dialysate temperature was normal (37 degrees C) and in three other sessions, the dialysate temperature was low (35 degrees C). Specific scale questionnaires were used in each dialysis session, to evaluate the symptoms during the dialysis procedure as well as post-dialysis fatigue, and respective scores were noted. The results showed that usage of low dialysate temperature was associated with the following: higher post dialysis systolic blood pressure (P< 0.05) and lower post dialysis heart rate (P< 0.01), with similar ultrafiltration rates, better intra-dialysis symptoms score and post-dialysis fatigue scores (P< 0.001, and P < 0.001, respectively), shorter post-dialysis fatigue period (P< 0.001) as well as higher urea removal (P< 00001) and Kt/V (P< 0.0001). Patients' perceptions were measured by a questionnaire, which showed that 76% of them felt more energetic after dialysis with cool dialysate and requested to be always dialyzed with cool dialysate. Low temperature dialysate is particularly beneficial for highly symptomatic patients, improves tolerance to dialysis in hypotensive patients and helps increase ultrafiltration while maintaining hemodynamic stability during and after dialysis.

    Patients with CKD exhibit significant within-patient hemoglobin (Hb) level variability, especially with the use of erythropoiesis stimulating agents (ESAs) and iron. Analyses of dialysis cohorts in the United States produced conflicting results regarding the association of Hb variability with patient outcomes. Here, we determined Hb variability in 5037 European hemodialysis (HD) patients treated over 2 years to identify predictors of high variability and to evaluate its association with all-cause and cardiovascular disease (CVD) mortality. We assessed Hb variability with various methods using SD, residual SD, time-in-target (11.0 to 12.5 g/dl), fluctuation across thresholds, and area under the curve (AUC). Hb variability was significantly greater among incident patients than prevalent patients. Compared with previously described cohorts in the United States, residual SD was similar but fluctuations above target were less frequent. Using logistic regression, age, body mass index, CVD history, dialysis vintage, serum albumin, Hb, angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) use, ESA use, dialysis access type, dialysis access change, and hospitalizations were significant predictors of high variability. Multivariable adjusted Cox regression showed that SD, residual SD, time-in-target, and AUC did not predict all-cause or CVD mortality during a median follow-up of 12.4 months (IQR: 7.7 to 17.4). However, patients with consistently low levels of Hb (<11 g/dl) and those who fluctuated between the target range and <11 g/dl had increased risks for death (RR 2.34; 95% CI: 1.24 to 4.41 and RR 1.74; 95% CI: 1.00 to 3.04, respectively). In conclusion, although Hb variability is common in European HD patients, it does not independently predict mortality. PMID:20798262

    Many long-term maintenance hemodialysis patients have symptoms of protein-energy wasting caused by malnutrition. Each session of hemodialysis removes about 10 to 12 g of amino acids and 200 to 480 kcal of energy. Patients receiving hemodialysis for chronic kidney disease may be undernourished for energy, protein consumption, or both. Non-diabetic hemodialysis patients were randomized to three treatment groups: oral supplementation, oral supplementation plus high-concentration glucose solution (250 mL containing 50% glucose) and these two interventions plus 8.5% amino acids solution. The post-treatment energy status of the glucose group was significantly higher than its baseline level, whereas the control group's status was significantly lower. The glucose group had significantly higher concentrations of asparagine, glutamine, glycine, alanine, and lysine after treatment. All treatment groups had significantly increased hemoglobin levels but significantly decreased transferrin levels after treatment compared to baseline. After treatment, the amino acid group had significantly higher albumin level compared to the glucose group (p = 0.001) and significantly higher prealbumin level compared to the control group (p = 0.017). In conclusion, long-term intervention with high-concentration glucose solution at each hemodialysis session is a simple and cheap method that replenished energy stores lost during hemodialysis of non-diabetic patients.

    Cerebral venous thrombosis is a rare condition with various clinical presentations which may delay diagnosis. It is frequently associated with severe consequences. We present the first documented case of thrombosis of the great cerebral vein in a hemodialysis patient. A 29-year-old female patient with end-stage renal disease of unknown etiology was admitted to a hospital with altered consciousness and nausea. Severe headache in the right parietal area had started 2 days before. On examination, she was in the poor overall condition, dysartric, with a severe nystagmus. Urgent brain multislice computerized tomography and magnetic resonance imaging revealed thrombosis of the great cerebral vein with hypodense zones in hypothalamus, thalamus and basal ganglia. She was treated with heparin bolus of 25000 IU with a favorable outcome. Detailed examination demonstrated increased lupus anticoagulant (LA) 1 and LA2 and increased LA1/LA2. Control magnetic resonance imaging performed 1 year later revealed multiple vascular lesions within the brain. Acetylsalicylate was introduced in therapy. Thrombosis of the cerebral veins should be suspected in patients with end-stage renal disease, altered neurological status and signs of increased intracranial pressure.

    End-stage renal disease results in anemia caused by shortened erythrocyte survival, erythropoietin deficiency, hepcidin-mediated impairment of intestinal absorption and iron release, recurrent blood loss, and impaired responsiveness to erythropoiesis-stimulating agents (ESAs). Iron malabsorption renders oral iron products generally ineffective, and intravenous (IV) iron supplementation is required in most patients receiving maintenance hemodialysis (HD). IV iron is administered at doses far exceeding normal intestinal iron absorption. Moreover, by bypassing physiologic safeguards, indiscriminate use of IV iron overwhelms transferrin, imposing stress on the reticuloendothelial system that can have long-term adverse consequences. Unlike conventional oral iron preparations, ferric citrate has recently been shown to be effective in increasing serum ferritin, hemoglobin, and transferrin saturation values while significantly reducing IV iron and ESA requirements in patients treated with HD. Ferric pyrophosphate citrate is a novel iron salt delivered by dialysate; by directly reaching transferrin, its obviates the need for storing administered iron and increases transferrin saturation without increasing serum ferritin levels. Ferric pyrophosphate citrate trials have demonstrated effective iron delivery and stable hemoglobin levels with significant reductions in ESA and IV iron requirements. To date, the long-term safety of using these routes of iron administration in patients receiving HD has not been compared to IV iron and therefore awaits future investigations.

We realized a descriptive study and analyzed the factors that were statistically associated with higher mortality: a surgical etiology, clinic criteria for the inicial of hemodialysis, respiratory failure, hemodynamic inestability, hepatic insufficciency, disseminated intravascular coagulacion and oliguric or anuria. The sepsis and the cardiorrespiratory complications were the cause of mortality most important. The 14% of the surviving requiring continue in the programs of hemodyalisis. PMID:7734664

    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.

    The aim of this prospective study was the assessment of left ventricular and right ventricular diastolic function in patients on hemodialysis (HD) and the correlation of this function with the duration of HD. The study included 42 patients (22 females and 20 males) with chronic renal failure (CRF), treated with HD, and 40 healthy subjects (24 females and 16 males) with no history of cardiovascular disease and with normal renal function, who constituted the control group. The groups were matched for age and sex. All study patients and control subjects underwent detailed history taking and physical examination. They also underwent electrocardiogram, echocardiography and biochemical and hematological blood analyses. Significant differences were noted between the two groups in the two-dimensional and M-mode echocardiography findings concerning aortic root dimension, transverse diameter of the left atrium, thickness of the interventricular septum, thickness of the left ventricular posterior wall, left ventricular diastolic diameter, left ventricular systolic diameter, shortening fraction, ejection fraction as well as findings from the pulse Doppler study, including E wave, A wave, E/A ratio, deceleration time of E wave (DT-E), acceleration time of E wave (AT-E), tricuspid E and A waves (E tr and A tr ) and E tr /A tr , ratio. There were significant changes in HD patients without arterial hypertension as well in the control group subjects. Our study suggests that the left ventricular and left atrial dimensions as well as the left ventricular wall thickness are augmented in patients with CRF treated with HD compared with the control group. Additionally, the left and right ventricular diastolic function is also reduced in these patients. These differences were also noted in patients with CRF without arterial hypertension. Left ventricular diastolic dysfunction had no correlation with the duration of HD.

    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

    Intradialytic hypotension is defined as a decrease in systolic blood pressure by ≥ 20 mm Hg or a decrease in mean arterial pressure by 10 mm Hg, and is associated with symptoms that include abdominal discomfort, yawning, sighing, nausea, vomiting, muscle cramps, restlessness, dizziness or fainting, and anxiety. The incidence of a symptomatic reduction in blood pressure during (or immediately following) dialysis ranges from 15-50% of dialysis sessions. It is a major cause for morbidity in elderly hemodialysis patients and those with cardiovascular compromise. It impairs patient well-being, limits ultrafiltration, and increases the risk for coronary and cerebral ischemic events as well as vascular access thrombosis. Several studies have shown a poorer survival in dialysis patients who experience frequent hypotensive episodes on dialysis as opposed to those who do not. In our outpatient dialysis unit, we identified that 9% of our dialysis patients experienced a decrease in their systolic blood pressure to below 80 during dialysis. The purpose of this quality improvement project was to study the factors associated with intradialytic hypotension in these patients and institute appropriate measures to mitigate this issue. Another aim was to educate the dialysis staff on how to manage these patients. Patients were selected using data from weekly rounding reports and orders were written for interventions including ultrafiltration profiling, cool (36 degrees C) dialysate, weight-based ultrafiltration, etc. Outcomes were studied over a period of 3 months. We found that up to 40% of patients experienced an improvement in their blood pressure profile over the period of the study, suggesting that simple changes to dialysis prescription can result in a significant reduction in the incidence of intradialytic hypotension.

    Prosthetic graft A-V fistulae (AVf) (10 adults) and internal AVf (14 adults) as avenues of hemodialysis were created surgically in the limbs of 24 renal failure patients. AVf can malfunction or become obstructed and to date only contrast fistulography (CnF) is used to document such problems. Thirty-three RnF's were performed in 24 patients and CnF's in seven patients. Eleven had clinical features of AVf malfunction and 13 were asymptomatic. 99mTc compounds, TcO/sup -//sub 4/ or MDP (20 mCi) were injected into the AVf through a 19-gauge butterfly. 2 sec. dynamic images (qualitative data) and simultaneous computer acquisition in 64 x 64 byte mode with 0.5 sec/frame for 120 frames (quantitative data) were obtained. Normal qualitative and quantitative criteria were established. 10/11 symptomatic and 2/13 asymptomatic patients showed abnormal scintigraphic features and time activity curves indicating AVf malfunction. All 12 patients demonstrated abnormal collateral formation; 8/12 had stenosis, 3/12 showed equivocal stenosis and in 1/12 no stenosis was shown. In these 12 patients the S/sub 2/ (second circulation)/S/sub 1/ (initial circulation) ratio was below 10%. In 5/12 whose S/sub 2//S/sub 1/ ratio was less than 1%, the CnF and surgical repair confirmed the presence of stenosis. RnF appears to be a simple, benign, and accurate imaging procedure in the evaluation of AVf malfunction.

    The recent emphasis on assessment of the psychological status, availability of newer and better methods of interpreting the anthropometric measurements of renal patients on dialysis therapy prompted the authors to develop the “Holistic Health Assessment Tool for dialysis patients (HHAT-D).” A total of 30 subjects (25–65 years), enrolled from dialysis centers in Mumbai were administered the HHAT-D tool to assess anthropometric, biochemical, functional, and psychological status (knowledge, needs, that coping strategies) along with dietary intake. The results showed that majority of the patients (73.3%) were mild to moderately malnourished. A highly significant negative correlation of anthropometric measurements (BMI, lean body mass, mid arm circumference, arm muscle area, bicep skin fold thickness, % usual body weight, and % standard body weight) with the HHAT-D scores (P<0.01) confirmed the validity of the tool in assessing the degree of malnutrition. The poor health status of the patients was further confirmed by the average (40%) to poor (36.6%) flexibility status and poor dietary nutrient intake. Moderate (36.6%) to high (60%) coping effectiveness was recorded in the patients as assessed using the “coping effectiveness inventory.” A high degree of interitem correlation (Cronbach's coefficient alpha-test value 0.836) also proved the reliability of the HHAT-D tool. Thus, the HHAT-D was found to be a specific and reliable tool for assessment of holistic health status of patients on maintenance hemodialysis to improve quality of life and facilitate faster recovery.

    Since the 1960s, regular hemodialysis (HD) was recognized as a risk factor for the development of infective endocarditis (IE), particularly at vascular access sites. The present report describes our experience at the Etat Major General Agadir, Morocco, of taking care of IE in patients on regular dialysis. A retrospective analysis was made of five cases of IE in patients receiving regular HD having arteriovenous fistula as vascular access. They were sent from four private centers and admitted in our formation between January 2004 and March 2009. Infective endocarditis was detected after 34.5 months following initiation of dialysis. The causative organisms included Staphylococcus and Enterococcus in two cases each and negative blood culture in one case. A recent history of infection (<3 months) of the vascular access was found in three cases. Peripheric embolic phenomena were noted in two cases. A pre-existing heart disease was common and contributed to heart failure. Mortality was frequent due to valvular perforations and congestive heart failure, making the medical treatment alone unsatisfactory. Two patients survived and three of our patients received a prosthetic valve replacement, with a median survival after surgery of 10.3 months/person. The clinical diagnosis of infective endocarditis in regularly dialyzed patients remains difficult, with the presence of vascular calcification as a common risk factor. The vascular catheter infections are the cardinal gateway of pathogenic organisms, which are mainly Staphylococcus. The prognosis is bad and the mortality is significant, whereas medical and surgical treatments are often established in these patients who have many factors of comorbidity. PMID:21196639

    Carnitine deficiency is a commonly observed problem in maintenance hemodialysis (MHD) patients, which results in altered metabolism of fatty acids and subsequently development of dyslipidemia. To evaluate the effect of oral L-carnitine (LC) supplementation on lipid profile of adult MHD patients, we studied 30 of them (19 males, 11 females) who received LC supplementation of 250 mg tablets three times a day for eight weeks. They were compared with 30 matched patients as a control group. Serum lipid profiles were compared before and after the intervention between the two groups. There was a significant decrease of the values of the lipid profile in the intervention group before and after carnitine supplementation including the mean values of total cholesterol (190 ± 36.8 vs. 177 ± 31.2 mg/dL), triglyceride (210 ± 64.7 vs. 190 ± 54.1 mg/dL) and LDL-cholesterol (117 ± 30.1 vs. 106 ± 26.3 mg/dL), while the values did not change siginificantly from base line in the control group. However, the difference for HDL-cholesterol in intervention group was not statistically significant. None of the patients dropped out of the study due to drug side effects. Oral LC supplementation (750 mg/day) is able to improve lipid profile in patients on MHD. Further long-term studies with adequate sample size are needed to define the population of patients who would benefit more from carnitine therapy and the optimal dose and the most efficient route for administration of the drug.

    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.

    Protein-energy malnutrition is a major problem and one of the risk factors for mortality in hemodialysis patients. There is no single index in evaluation of nutritional status in these patients, so leptin can be used as one of the parameters. In this study, the correlation between serum leptin with biochemical and anthropometric parameters of nutrition has been evaluated. This cross-sectional study has been performed on 60 hemodialysis patients (32 males and 28 females) in 2006. The patients on hemodialysis for under 1 year and who has a history of consumption of lipid lowering agents or glucocorticoids, or an infectious or inflammatory disease were excluded. Malnutrition laboratory parameters and serum leptin were measured before hemodialysis. Serum leptin was measured with enzyme-linked immunosorbent assay (ELISA) method with direct dbc kit and malnutrition laboratory parameters measured with standard laboratory methods, patients anthropometric parameters evaluated after hemodialysis. The mean age of patients was 47.5 ± 16.1 years and the range of serum leptin level was 0.6-64.8 ng/ml. Mean serum leptin level were 22.64 ± 19.54 ng/ml in females and 16.74 ± 20.16 ng/ml in males on hemodialysis and in spite of higher level of leptin in females there was not any statistically significant difference between females and males serum leptin. Absolute value of correlation coefficient between serum leptin and anthropometric parameters and most laboratory parameters was < 0.25 (except ferritin, iron, phosphorous in males and total protein, hemoglobin, urea, and creatinin in females which was between 0.25 and 0.50). Our results suggest that the increased serum leptin level does not have a major role in diagnosis of malnutrition in hemodialysis patients and there is a poor correlation between malnutrition parameters and serum leptin level.

    Malnutrition is a frequent complication in hemodialysis patients and is associated with increased mortality and morbidity. Interventions such as oral or intravenous nutritional supplements have often failed to improve nutritional status. We report here the effect that daily dialysis, practiced in our center since 1997, has had on nutritional parameters. Seventeen patients treated with conventional hemodialysis (4-5 hours, three times per week, for 9.6 +/- 8.4 years) were converted to short daily hemodialysis (2-2.5 hours, six times per week, for a mean of 39.1 +/- 23.5 months). Dietary, anthropometric, and biochemical evaluations were performed during conventional hemodialysis, after 1 year on short daily hemodialysis (sDHD(year)), and at the end of follow-up (sDHD(end)). Daily protein intake increased from 1.21 +/- 0.27 g/kg/day with conventional hemodialysis to 1.51 +/- 0.47 g/kg/day at sDHD(year) and 1.51 +/- 0.37 g/kg/day at sDHD(end). Energy intake increased from 33.6 +/- 9.5 kcal/kg/day to 38.3 +/- 10.9 kcal/kg/day at sDHD(year) and 39.4 +/- 9.4 kcal/kg/day at sDHD(end). The normalized protein equivalent nitrogen appearance (nPNA) increased from 1.19 +/- 0.34 g/kg/day with conventional hemodialysis to 1.34 +/- 0.43 g/kg/day sDHD(year) and 1.37 +/- 0.37 g/kg/day sDHD(end). Biochemical indicators also increased: serum albumin increased from 40.2 +/- 3.3 g/L to 44.5 +/- 4.6 g/L and 45.1 +/- 4.1 g/L, and prealbumin increased from 0.32 +/- 0.06 g/L to 0.38 +/- 0.09 g/L and 0.36 +/- 0.09 g/L, respectively. These improvements were accompanied by an increase in body weight from 62.0 +/- 10.6 kg on conventional hemodialysis to 64.3 +/- 10.2 kg at sDHD(year) and 65.5 +/- 9.7 kg at sDHD(end). All the changes between conventional hemodialysis and short daily hemodialysis were statistically significant. Increased frequency is more important than increased dialysis dose. Short daily hemodialysis appears to be a suitable method to improve nutritional status in dialysis

    Recently, the Geriatric Nutritional Risk Index (GNRI) has been introduced as a valuable tool to assess the nutritional status of hemodialysis (HD) patients. To determine the predictive value of the GNRI score for death in HD, we studied 145 chronic HD patients (%53 men, mean age 60 ± 16 years). The GNRI score was estimated by an equation involving serum albumin and individual's weight and height. According to the highest positive likelihood and risk ratios, the cut-off value of the GNRI for mortality was set at 100. The survival of patients on HD was examined with the Cox proportional hazards model. Mortality was monitored prospectively over an 18-month period, during which 35 patients died. The GNRI (mean 102.6 ± 5.5) was significantly positively correlated with lean body mass, hematocrit, serum lipids and presence of metabolic syndrome. Multivariate Cox proportional hazards analysis demonstrated that the GNRI <100, serum ferritin ≥ 500 μ g/L and age 65 years or older were significant predictors for mortality (hazard ratio 3.691, 95% CI 1.751-7.779, P = 0.001; hazard ratio 3.105, 95% CI 1.536-6.277, P = 0.002; and hazard ratio 2.806, 95% CI 1.297-6.073, P = 0.009, respectively), after adjustment to gender and vintage time. It can be concluded that, in addition to old age, malnutrition (low GNRI) and inflammation (high ferritin) are identified as significant independent risk factors that predict all-cause mortality in HD patients.

    Background: Sleep disorders and depression, accompanied by reduced quality of life and increased mortality are the most common psychological problems in dialysis patients. This study was conducted with the aim to investigate depression and sleep quality and their association with some demographic and clinical factors in hemodialysis patients. Method: This descriptive-correlative study was conducted on 310 patients undergoing hemodialysis in 8 centers in educational hospitals in Mazandaran University of Medical Sciences. Data collection tools included a demographic questionnaire, Beck Depression Inventory, and Pittsburg Sleep Quality Index (PSQI). Statistical analysis was conducted using Chi-Square test and regression model. Results: Results obtained showed 44.8% depression in patients. Significant relationships were found between depression and increased blood phosphorus (P=0.002) and urea (P=0.001). Poor sleep quality was observed in 73.5% of hemodialysis patients, which was found significantly related to aging (P=0.048), female (P=0.04), and reduced frequency of weekly hemodialysis (P=0.035). Conclusion: Depression and poor sleep quality are two common factors in hemodialysis patients, but patients do not overtly show symptoms of these disorders.

    Objective Patients with diabetes are at increased risk of foot ulcers, which may result in limb amputations. While regular foot care prevents ulcerations and amputation in those patients with diabetes not on dialysis, evidence is limited in diabetic hemodialysis patients. We investigated the association between the implementation of a routine foot check program in diabetic incident hemodialysis patients, and major lower limb amputations. Methods In 1/2008, monthly intradialytic foot checks were implemented as part of standard clinic care in all Fresenius Medical Care North America hemodialysis facilities. Patients with diabetes who initiated hemodialysis between 1/2004 and 12/2007 constituted the preimplementation cohort, and patients starting hemodialysis between 1/2008 and 12/2011 comprised the postimplementation cohort. In addition, we conducted a sensitivity analysis where we excluded patients from the clinics with <10 patients in the postimplementation period and where percent difference in patient with diabetes number between postimplementation and preimplementation period was <20%. We compared lower limb amputation rates employing Poisson regression models with offset of exposure time in these two cohorts. Results We studied 35 513 patients in the preimplementation and 25 779 patients in the postimplementation cohort. In the postimplementation cohort, amputation rate decreased by 17% (p=0.0034). The major lower limb amputation rate was 1.30 per 100 patient years in preimplementation and 1.07 in postimplementation cohort. These beneficial results were corroborated in the multivariate analysis (p=0.0175) and were even more pronounced in the sensitivity analysis (p=0.0083). Conclusion Monthly foot checks are associated with reduction of major lower limb amputations in diabetic incident hemodialysis patients. PMID:26958348

    The clinical outcomes of nitinol stents for femoropopliteal arterial (FP) disease in patients on hemodialysis were assessed. Endovascular therapy (EVT) is accepted for symptomatic FP disease. However, the clinical outcomes of patients on dialysis are not well known. A multicenter retrospective study was conducted with data between November 2010 and August 2013. A total of 484 consecutive patients who successfully underwent EVT for FP disease with nitinol stents were recruited and analyzed. Patients were categorized into the hemodialysis group (N = 161) and non-hemodialysis group (N = 323). The primary measure was primary patency verified by duplex ultrasound at a rest peak systolic velocity (PSVR) of >2.5, and secondary measures were freedom from target lesion revascularization (TLR) and major amputation-free survival (AFS). Average follow-up duration was 19.5 ± 13.5 months. The primary patency rate at 3 years was significantly lower in the hemodialysis group than the non-hemodialysis group (33.8 vs. 43.7 %; p = 0.036). Freedom from TLR at 3 years was 55.0 % in the hemodialysis group and 66.1 % in the non-hemodialysis group (p = 0.032). The hemodialysis group showed a significantly lower AFS rate at 3 years than the non-hemodialysis group (86.4 vs. 58.2 %; p < 0.001). In hemodialysis patients, nitinol stent use resulted in a lower patency rate, higher TLR rate, and lower AFS rate compared to non-hemodialysis patients. These data suggest that nitinol stent implantation for FP arteries in hemodialysis patient needs to be reconsidered. PMID:26337619

    We studied the response of heart rate variability to hemodialysis and orthostatism using traditional linear indexes and 9 recurrence quantification analysis indexes to reveal changes in the heart rate dynamics. Twenty healthy subjects and 19 chronic renal failure patients treated with hemodialysis thrice a week were included. Five-minute heart rate variability time series were obtained during supine position (clinostatism) and orthostatism from each participant; recordings in renal patients were repeated after hemodialysis. Linear indexes were consistent with sympathetic predominance in response to orthostatism in the control group. Renal patients before hemodialysis showed increased sympathetic predominance in clinostatism, with further increase in orthostatism and hemodialysis. In response to orthostatism, 4 recurrence indexes changed in the control group, while in renal patients any of them changed before hemodialysis and 1 changed after hemodialysis. In clinostatism, renal patients (both before and after hemodialysis) had higher laminarity, trapping time, and recurrence time than the control group. Recurrence indexes showed that the heart rate dynamics in renal patients are different from healthy subjects, suggesting loss of access to some regulatory conditions. These findings are consistent with reports of sympathetic stimulation induced by hemodialysis and active standing.

    Background Sudden cardiac death is one of the primary causes of mortality in chronic hemodialysis (HD) patients. Prolonged QTc interval is associated with increased rate of sudden cardiac death. The aim of this article is to assess the abnormalities found in electrocardiograms (ECGs), and to explore factors that can influence the QTc interval. Methods A total of 141 conventional HD patients were enrolled in this study. ECG tests were conducted on each patient before a single dialysis session and 15 minutes before the end of dialysis session (at peak stress). Echocardiography tests were conducted before dialysis session began. Blood samples were drawn by phlebotomy immediately before and after the dialysis session. Results Before dialysis, 93.62% of the patients were in sinus rhythm, and approximately 65% of the patients showed a prolonged QTc interval (i.e., a QTc interval above 440 ms in males and above 460ms in females). A comparison of ECG parameters before dialysis and at peak stress showed increases in heart rate (77.45±11.92 vs. 80.38±14.65 bpm, p = 0.001) and QTc interval (460.05±24.53 ms vs. 470.93±24.92 ms, p<0.001). After dividing patients into two groups according to the QTc interval, lower pre-dialysis serum concentrations of potassium (K+), calcium (Ca2+), phosphorus, calcium* phosphorus (Ca*P), and higher concentrations of plasma brain natriuretic peptide (BNP) were found in the group with prolonged QTc intervals. Patients in this group also had a larger left atrial diameter (LAD) and a thicker interventricular septum, and they tended to be older than patients in the other group. Then patients were divided into two groups according to ΔQTc (ΔQTc = QTc peak-stress- QTc pre-HD). When analyzing the patients whose QTc intervals were longer at peak stress than before HD, we found that they had higher concentrations of Ca2+ and P5+ and lower concentrations of K+, ferritin, UA, and BNP. They were also more likely to be female. In addition, more cardiac

    Background Patients on hemodialysis often experience muscle cramps that result in discomfort, shortened treatment times, and inadequate dialysis dose. Cramps have been associated with adversely affecting sleep and health-related quality of life, depression and anxiety. There is limited evidence available about massage in dialysis; however, massage in cancer patients has demonstrated decreases in pain, inflammation, and feelings of anxiety. These correlations indicate massage may be an effective treatment modality for hemodialysis-related lower extremity cramping. Purpose To determine the effectiveness of intradialytic massage on the frequency of cramping among hemodialysis patients prone to lower extremity cramping. Participants 26 maintenance hemodialysis patients with frequent lower extremity cramps. Setting three outpatient hemodialysis centers in Northeast Ohio. Research Design randomized controlled trial. Intervention The intervention group received a 20-minute massage of the lower extremities during each treatment (three times per week) for two weeks. The control group received usual care by dialysis center staff. Main Outcome Measure change in frequency of lower leg cramping. Results Patient reported cramping at home decreased by 1.3 episodes per week in the intervention group compared to 0.2 episodes per week in the control group (p=.005). Patient reported cramping during dialysis decreased by 0.8 episodes in the intervention group compared to 0.4 episodes in the control group (p=0.44). Conclusion Intradialytic massage appears to be an effective way to address muscle cramping. Larger studies with longer duration should be conducted to further examine this approach. PMID:27257445

    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.

    The aims of this study were to analyse body composition, to detect the presence of undernutrition, and to establish a relationship between undernutrition and the biological markers routinely used as indicators of nutritional status in hemodialysis (HD) patients (pts). We used a body composition monitor (BCM) that expresses body weight in terms of lean tissue mass (LTM) and fat tissue mass (FTM) independent of hydration status. From nine HD units, 934 pts were included. Undernutrition was defined as having a lean tissue index (LTI = LTM/height2) below the 10th percentile of a reference population. Biochemical markers and parameters delivered by BCM were used to compare low LTI and normal LTI groups. Undernutrition prevalence was 58.8% of the population studied. Low LTI pts were older, were significantly more frequently overhydrated, and had been on HD for a longer period of time than the normal LTI group. FTI (FTI = FTM/ height2) was significantly higher in low LTI pts and increased according to BMI. LTI was not influenced by different BMI levels. Albumin and C-reactive protein correlated inversely (r = −0.28). However neither of them was statistically different when considering undernourished and normal LTI pts. Our BCM study was able to show a high prevalence of undernutrition, as expressed by low LTI. In our study, BMI and other common markers, such as albumin, failed to predict malnutrition as determined by BCM. PMID:27347538

    This article aims to provide an overview of the different nutritional markers and the available methodologies for the physical assessment of nutrition status in hemodialysis patients, with special emphasis on early detection of protein energy wasting (PEW). Nutrition status assessment is made on the basis of anamnesis, physical examination, evaluation of nutrient intake, and on a selection of various screening/diagnostic methodologies. These methodologies can be subjective, e.g. the Subjective Global Assessment score (SGA), or objective in nature (e.g. bioimpedance analysis). In addition, certain biochemical tests may be employed (e.g. albumin, pre-albumin). The various subjective-based and objective methodologies provide different insights for the assessment of PEW, particularly regarding their propensity to differentiate between the important body composition compartments-fluid overload, fat mass and muscle mass. This review of currently available methods showed that no single approach and no single marker is able to detect alterations in nutrition status in a timely fashion and to follow such changes over time. The most clinically relevant approach presently appears to be the combination of the SGA method with the bioimpedance spectroscopy technique with physiological model and, additionally, laboratory tests for the detection of micro-nutrient deficiency.

The study, of transverse type descriptive, carried out of September 15 to December 31, 2014, is unrolled with the CHU-YO. This descriptive transversal study was conducted at the CHU-YO from September 15 to December 31, 2014. It involved patients who had been on chronic dialysis for at least 3 months. The frequency of hemodialysis sessions was one every five days. The significance level of statistical tests was defined as the probability p ≤ 0.05. Eighty-five patients (61.1% men and 38.9% women) with an average age of 42.1 years were included in the study. The mean duration of hemodialysis was 31.9 months. The success rate of biological examinations varied from 7,4 to 85,3%. Eighty patients (85,3%) had at least one cutaneous manifestation. Cutaneous xerosis (67.4%), pruritus (45.3%), and hyperpigmentation (23.2%) were the most frequent skin manifestations that may be specific of hemodialysis. Guttate hypomelanosis (11.6%), prurigo (11.6%) and folliculitis (8.4%) were the main non-specific skin manifestations. Skin involvement was frequent but did not seem related to seniority in hemodialysis. In Ouagadougou, bad hemodialysis conditions and a hot, dry environment promote such conditions, especially xerosis and pruritus. A better subvention of health care could help to reduce the prevalence of skin diseases and to improve the quality of life of our patients on chronic hemodialysis.

    The purpose of this study was to reveal the unique sound characteristics of the bruit produced by arteriovenous fistulae (AVF), using a computerized method. An electronic stethoscope (20 Hz to 20 000 Hz sensitivity) was used, connected to a portable laptop computer. Forty prevalent hemodialysis patients participated in the study. All measurements were made with patients resting in supine position, prior to the initiation of mid-week dialysis session. Standard color Doppler technique was used to estimate blood flow. Clinical examination revealed the surface where the perceived bruit was more intense, and the recording took place at a sample rate of 22 000 Hz in WAV lossless format. Fast Fourier Transform (FFT) mathematical algorithm, was used for the sound analysis. This algorithm is particularly useful in revealing the periodicity of sound data as well as in mapping its frequency behavior and its strength. Produced frequencies were divided into 40 frequency intervals, 250 Hz apart, so that the results would be easier to plot and comprehend. The mean age of the patients was 63.5 ± 14 years; the median time on dialysis was 39.6 months (mean 1 month, max. 200 months). The mean blood flow was 857.7 ± 448.3 ml/min. The mean sound frequency was approximately 5 500 Hz ± 4 000 Hz and the median, which is also expressing the major peak of sound data, was 750 Hz, varying from 250 Hz to 10 000 Hz. A possible limitation of the study is the relatively small number of participants.

    Mesenteric ischemia among chronic dialysis patients is usually of the nonocclusive type. Chronic occlusive mesenteric ischemia has been reported rarely in the dialysis population. The subset of"celiac-territory ischemic syndrome" has not been described in dialysis. The current report involves a 66-year-old female on chronic dialysis for 11 years. She experienced abdominal pain following sessions of hemodialysis, that later became more pronounced after eating. Abdominal angiography showed heavily calcified aorta, celiac trunk and superior mesenteric artery (SMA), with a 50% narrowing of the celiac and superior mesenteric arteries. During the following 9 months the symptoms worsened and weight loss set in. She was admitted with an episode of upper abdominal pain. Acalculous cholecystitis was found, along with multiple gastric and duodenal erosions including the second part, with an antral ulcer and multiple duodenal bulb ulcers. Repeated abdominal angiography showed progression of the stenotic lesions with significant narrowing of both the celiac trunk and the SMA. A stent was placed in the SMA. Following the procedure, the patient noted marked symptomatic improvement. On follow-up gastroduodenoscopy, all ischemic ulcers had healed completely. Serum albumin rose from a nadir of 31 to 40 g/l, and an extremely elevated c-reactive protein of 205,000 microg/l returned to normal (8,000 microg/l). The diagnosis of chronic occlusive mesenteric ischemia should be suspected among dialysis patients with post-prandial pain and weight loss in the face of calcified vessels. Predominant celiac territory ischemic syndrome presents as gastric and duodenal erosions and ulcers with or without acalculous cholecystitis. PMID:17969495

    The goal of our dynamic progressive care unit patient education program was to empower hemodialysis patients to learn to be as independent in their hemodialysis treatments as their condition permitted, whether in the home or in the clinical setting. The paradigm shift that has placed patient education at the centre of health care has necessitated a practice change for both patients and nurses. In response to this change and to assist us to achieve our goal, a set of 14 hemodialysis teaching protocols has been developed. Individual protocols address specific aspects of the management of hemodialysis treatments and implementation, and are based upon the nursing process. Each protocol has an accompanying documentation and evaluation tool and can be used as an indicator for continuous quality improvement. Our success to date is evident in the placement of patients along the continuum of limited self-care starting in the progressive care unit and continuing to achieve increased independence by dialyzing in their own homes as part of the home hemodialysis program.

Correlations between nonlinear HRV indices and left-ventricular ejection fraction (LVEF), left-ventricular end-diastolic volume (LVEDV), extracellular volume (ECV)/total-body water (TBW) ratio, the SF-36 Physical Health Composite (PHC) and Physical Functioning scores (PF) were tested. Results We studied 210 subjects [average age 49.8±13.5 years, 62% males, 42% diabetics]. In non-diabetic patients, MSE SampEn and MSE ApEn correlated positively with LVEF, PF, PH, and inversely with LVEDV and ECV/TBW. SPS correlated positively with ECV/TBW (r=0.27). Irregularity measures (MSE ApEn, MSE SampEn) correlated positively with LVEDV (r=0.19 and 0.20). Conclusion Nonlinear HRV indices indicated an association between a deteriorated heart rate regulatory system and impaired cardiac function, fluid accumulation and poor physical condition.

    Background and Objectives Infections are common complications among patients on chronic hemodialysis. This population-based cohort study aims to estimate risk and case fatality of bloodstream infection among chronic hemodialysis patients. Methods In this population-based cohort study we identified residents with end-stage renal disease in Central and North Jutland, Denmark who had hemodialysis as first renal replacement therapy (hemodialysis patients) during 1995–2010. For each hemodialysis patient, we sampled 19 persons from the general population matched on age, gender, and municipality. Information on positive blood cultures was obtained from regional microbiology databases. All persons were observed from cohort entry until first episode of bloodstream infection, emigration, death, or end of hemodialysis treatment, whichever came first. Incidence-rates and incidence-rate ratios were computed and risk factors for bloodstream infection assessed by Poisson regression. Case fatality was compared by Cox regression. Results Among 1792 hemodialysis patients and 33 618 matched population controls, we identified 461 and 1126 first episodes of bloodstream infection, respectively. Incidence rates of first episode of bloodstream infection were 13.7 (95% confidence interval (CI), 12.5–15.0) per 100 person-years among hemodialysis patients and 0.53 (95% CI, 0.50–0.56) per 100 person-years among population controls. In hemodialysis patients, the most common causative microorganisms were Staphylococcus aureus (43.8%) and Escherichia coli (12.6%). The 30-day case fatality was similar among hemodialysis patients and population controls 16% (95% CI, 13%–20%) vs. 18% (95% CI, 15%–20%). Conclusions Hemodialysis patients have extraordinary high risk of bloodstream infection while short-term case fatality following is similar to that of population controls. PMID:25910221

    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

    Expression of bone proteins resulting from transdifferentiation of vascular smooth muscle cells into osteoblasts suggests that vascular calcifications are a bioactive process. Regulating molecules such as osteoprotegerin (OPG) and receptor activator of NF-kappaB ligand (RANKL) could play a key role in bone-vascular calcification imbalance. This study investigated the contribution of these proteins as well as mineral metabolism disorders in hemodialysis (HD) patient outcome. A total of 185 HD patients were followed up prospectively for 2 yr. In addition to clinical characteristics, mineral metabolism markers as well as OPG and soluble RANKL (sRANKL) were measured at baseline. After 2 yr, survival rates were described with Kaplan-Meier and compared with Cox regression analyses; 50 patients died (27 from cardiovascular diseases). Calcium, phosphate, and calcium x phosphate product were not associated with mortality. Both hyperparathyroidism (parathyroid hormone > or =300 pg/ml) and hypoparathyroidism (parathyroid hormone <150 pg/ml) were poorly associated with all-cause and cardiovascular mortality. By contrast, elevated OPG levels predicted all-cause (relative risk [RR] 2.67; 95% confidence interval [CI] 1.32 to 5.41; P = 0.006) and cardiovascular mortality (RR 3.15; 95% CI 1.14 to 8.69; P = 0.03). Low levels of sRANKL were associated with a protective effect for all-cause mortality (RR 0.45; 95% CI 0.21 to 0.94; P = 0.03). The association of OPG with all-cause mortality was stronger in patients with C-reactive protein > or =12.52 mg/L. In this condition, both highest (RR 5.68; 95% CI 1.48 to 22.73; P = 0.01) and lowest tertiles (RR 5.37; 95% CI 147 to 1968; P = 0.01) significantly predicted poor outcome. These results show that regulating-bone molecules, especially OPG, are strong predictors of mortality in HD patients, suggesting that OPG is a vascular risk factor, in particular in patients who have high C-reactive protein levels. OPG determination therefore should

    Zinc is needed for growth and development, DNA synthesis, neurosensory functions, and cell-mediated immunity. Although zinc intake is reduced in elderly people, its deficiency and effects on cell-mediated immunity of the elderly have not been established. Subjects enrolled in "A Model Health Promotion and Intervention Program for Urban Middle Aged and Elderly Americans" were assessed for nutrition and zinc status. One hundred eighty healthy subjects were randomly selected for the study. Their mean dietary zinc intake was 9.06 mg/day, whereas the recommended dietary allowance is 15 mg/day. Plasma zinc was normal, but zinc in granulocytes and lymphocytes were decreased compared with younger control subjects. Of 118 elderly subjects in whom zinc levels in both granulocytes and lymphocytes were available, 36 had deficient levels. Plasma copper was increased, and interleukin 1 (IL-1) production was significantly decreased. Reduced response to the skin-test antigen panel and decreased taste acuity were observed. Thirteen elderly zinc-deficient subjects were supplemented with zinc, and various variables were assessed before and after zinc supplementation. Zinc supplementation corrected zinc deficiency and normalized plasma copper levels. Serum thymulin activity, IL-1 production, and lymphocyte ecto-5'-nucleotidase increased significantly after supplementation. Improvement in response to skin-test antigens and taste acuity was observed after zinc supplementation. A mild zinc deficiency appears to be a significant clinical problem in free-living elderly people. PMID:8353362

    Hemodialysis patients, due to a dysfunction of the immune response, are prone to a variety of opportunistic infections. Studies of intestinal parasitic infections in these patients are limited. Therefore, the present study was performed to determine the prevalence of these infections in patients on hemodialysis in Bushehr. In this cross-sectional study, fecal samples have been collected from all hemodialysis patients who were continuously referred from September 2011 to September 2012 to the dialysis center at Bushehr and tested using routine parasitological methods. From a total of 88 patients studied, 25 patients (28.4%) were infected with one or more intestinal parasites. Blastocystis hominis and Entamoeba coli with 13.6% and 6.7% prevalence had the highest prevalence among the patients, respectively. The age group 51-70 years had the highest rates of infection. Statistical analysis showed no relationship between sex and the risk of intestinal parasites. Seventeen percent of infected patients showed up with diarrhea and this relationship was statistically significant. Considering the high prevalence of intestinal parasitic infection among hemodialysis patients in Bushehr and also the high probability of infection in these patients, it is recommended that periodic examinations and screening patients during dialysis and before kidney transplantation should be a part of routine medical care.

    Introduction: Renalase is a protein secreted in kidneys and considered as a blood pressure modulator. High rates of hypertension and its regulation in patients on hemodialysis demands search for potential cause and treatment. The aim of this study was to determine the genotype and allele frequencies of renalase gene rs2576178 polymorphism in population from Bosnia and Herzegovina. Also, the objective of present study was to find the possible association between renalase gene rs2576178 polymorphism and hypertension in patients on hemodialysis. Material and Methods: The genotype of renalase gene rs2576178 polymorphism was determined in 137 participants (100 patients on hemodialysis and 37 controls), using polymerase chain reaction (PCR) and subsequent cleavage with MspI restriction endonuclease. Genotype and allele frequencies were assessed for Hardy-Weinberg equilibrium using a Chi-squared test. The value of P<0.05 was considered as statistically significant. Results: Comparison of genotype distribution and allele frequency in participants on hemodialysis with and without hypertension, and healthy control showed no statistical difference. Conclusion: The results of the study suggest that renalase gene rs2576178 polymorphism is not a factor that influences blood pressure in patients on hemodialysis. PMID:26980928

    Combination chemotherapy of mFOLFOX6 (5-fluorouracil, leucovorin, and oxaliplatin) plus panitumumab, a fully human monoclonal antibody against epidermal growth factor receptor (EGFR), is one of the standard treatments for metastatic colorectal cancer (mCRC) without KRAS mutation. A few reports suggested no need of dose adjustment of cetuximab, a similar chimeric anti-EGFR antibody, in patients with renal impairment. However, panitumumab combined with cytotoxic drugs for hemodialysis patients has not been reported.

    Background Patients with end-stage renal disease are at high risk for medical errors given their comorbidities, polypharmacy and coordination of care with other hospital departments. We previously developed a hemodialysis safety checklist (Hemo Pause) to be jointly completed by nurses and patients. Our objective was to determine the feasibility of using this checklist during every hemodialysis session for 3 months. Methods We conducted a single-center, prospective time series study. A convenience sample of 14 nurses and 22 prevalent in-center hemodialysis patients volunteered to participate. All participants were trained in the administration of the Hemo Pause checklist. The primary outcome was completion of the Hemo Pause checklist, which was assessed at weekly intervals. We also measured the acceptability of the Hemo Pause checklist using a local patient safety survey. Results There were 799 hemodialysis treatments pre-intervention (13 January–5 April 2014) and 757 post-intervention (5 May–26 July 2014). The checklist was completed for 556 of the 757 (73%) treatments. Among the hemodialysis nurses, 93% (13/14) agreed that the checklist was easy to use and 79% (11/14) agreed it should be expanded to other patients. Among the hemodialysis patients, 73% (16/22) agreed that the checklist made them feel safer and should be expanded to other patients. Conclusions The Hemo Pause safety checklist was acceptable to both nurses and patients over 3 months. Our next step is to spread this checklist locally and conduct a mixed methods study to determine mechanisms by which its use may improve safety culture and reduce adverse events. PMID:27274816

    Background Chronic kidney disease is a disorder of epidemic proportions that impairs cardiac function. Cardiovascular diseases are the leading cause of death in hemodialysis patients, and the understanding of new nontraditional predictors of mortality could improve their outcomes. Right ventricular systolic dysfunction (RVSD) has recently been recognized as a predictor of cardiovascular death in heart failure and hemodialysis patients. However, the factors contributing to RVSD in hemodialysis patients remain unknown. The aim of this study was to evaluate the clinical and echocardiographic factors associated with RVSD in hemodialysis patients. Methods A cross-sectional study was conducted in which 100 outpatients with end-stage renal disease on chronic hemodialysis were evaluated. A transthoracic echocardiographic examination was performed at optimal dry weight. Right ventricular systolic function was evaluated using tricuspid annular plane systolic excursion (TAPSE). Clinical and echocardiographic data were recorded for each patient. A multivariate linear logistic regression was created using RVSD (TAPSE <14 mm) as the dependent variable. Results Fifteen patients with RVSD and 85 patients without RVSD were analyzed. TAPSE had a positive correlation with left ventricular ejection fraction (LVEF) and myocardial relaxation velocity. Independent contributors to RVSD were LVEF (OR 1.14, 95% CI 1.05-1.26), left ventricular mass index (OR 1.02, 95% CI 1.00-1.04), and myocardial relaxation velocity (OR 1.81, 95% CI 1.18-3.19). Conclusions Echocardiographic factors were significant contributors to RVSD. These measurements could be included as part of the routine workup in all end-stage renal disease patients on hemodialysis. PMID:27275159

    Dialysis patients exhibit an inverse, L- or U-shaped association between blood pressure and mortality risk, in contrast to the linear association in the general population. We prospectively studied 9333 hemodialysis patients in France, aiming to analyze associations between predialysis systolic, diastolic, and pulse pressure with all-cause mortality, cardiovascular mortality, and nonfatal cardiovascular endpoints for a median follow-up of 548 days. Blood pressure components were tested against outcomes in time-varying covariate linear and fractional polynomial Cox models. Changes throughout follow-up were analyzed with a joint model including both the time-varying covariate of sequential blood pressure and its slope over time. A U-shaped association of systolic blood pressure was found with all-cause mortality and of both systolic and diastolic blood pressure with cardiovascular mortality. There was an L-shaped association of diastolic blood pressure with all-cause mortality. The lowest hazard ratio of all-cause mortality was observed for a systolic blood pressure of 165 mm Hg, and of cardiovascular mortality for systolic/diastolic pressures of 157/90 mm Hg, substantially higher than currently recommended values for the general population. The 95% lower confidence interval was approximately 135/70 mm Hg. We found no significant correlation for either systolic, diastolic, or pulse pressure with myocardial infarction or nontraumatic amputations, but there were significant positive associations between systolic and pulse pressure with stroke (per 10-mm Hg increase: hazard ratios 1.15, 95% confidence interval 1.07 and 1.23; and 1.20, 1.11 and 1.31, respectively). Thus, whereas high pre-dialysis blood pressure is associated with stroke risk, low pre-dialysis blood pressure may be both harmful and a proxy for comorbid conditions leading to premature death.

    Background The kinetics of protein transport to and from the vascular compartment play a major role in the determination of fluid balance and plasma refilling during hemodialysis (HD) sessions. In this study we propose a whole-body mathematical model describing water and protein shifts across the capillary membrane during HD and compare its output to clinical data while evaluating the impact of choosing specific values for selected parameters. Methods The model follows a two-compartment structure (vascular and interstitial space) and is based on balance equations of protein mass and water volume in each compartment. The capillary membrane was described according to the three-pore theory. Two transport parameters, the fractional contribution of large pores (αLP) and the total hydraulic conductivity (LpS) of the capillary membrane, were estimated from patient data. Changes in the intensity and direction of individual fluid and solute flows through each part of the transport system were analyzed in relation to the choice of different values of small pores radius and fractional conductivity, lymphatic sensitivity to hydraulic pressure, and steady-state interstitial-to-plasma protein concentration ratio. Results The estimated values of LpS and αLP were respectively 10.0 ± 8.4 mL/min/mmHg (mean ± standard deviation) and 0.062 ± 0.041. The model was able to predict with good accuracy the profiles of plasma volume and serum total protein concentration in most of the patients (average root-mean-square deviation < 2% of the measured value). Conclusions The applied model provides a mechanistic interpretation of fluid transport processes induced by ultrafiltration during HD, using a minimum of tuned parameters and assumptions. The simulated values of individual flows through each kind of pore and lymphatic absorption rate yielded by the model may suggest answers to unsolved questions on the relative impact of these not-measurable quantities on total vascular refilling and

    Twenty-five hemodialysis patients were randomized into comparable exercising (E, N = 14) and sedentary control (N = 11) groups. After baseline testing, training was 3 to 5 times weekly for a mean of 12 +/- 4 (SD) months. Maximal aerobic capacity increased 21% (P less than 0.01), and the durations for the graded exercise stress test improved 19% (P less than 0.01) in E, but did not change in controls (8 +/- 4 months). Declining blood pressures in 8 hypertensive E led to reductions in antihypertensive medications; no changes occurred in 9 hypertensive controls. Exercise lowered plasma total triglyceride levels 33% (280 +/- 258 to 175 +/- 95 mg/dl; P less than 0.01), but no change occurred in total and low-density lipoprotein cholesterol concentrations. High-density lipoprotein cholesterol levels rose 16% in E (31 +/- 9 to 36 +/- 12 mg/dl; P less than 0.02), but did not change in controls. An increase in the affinity of insulin for receptors on mononuclear cells was associated with a 20% decrease in fasting plasma insulin levels (24 +/- 7 to 19 +/- 2 microU/ml, N = 8; P less than 0.05) and a 42% improvement in glucose disappearance rates (1.9 +/- 1.0 to 2.6 +/- 1.2% per min, N = 6) in E. There were no changes in the body weights or diets of the patients. A 27% increase in red blood cell mass (P less than 0.02) with no change in plasma volume resulted in a 27% increase in hematocrit (24 +/- 3% to 31 +/- 5%, P less than 0.01) and a 20% increase in hemoglobin (8 +/- 1 to 10 +/- 2 g/dl; P less than 0.01) in E.(ABSTRACT TRUNCATED AT 250 WORDS)

    Secondary hyperparathyroidism is a common complication in chronic renal failure. The treatment in some cases requires parathyroidectomy. The kinetics of the parathyroid hormone (PTH) levels after surgery helps to evaluate the efficacy of parathyroidectomy. Prospective analysis was made of the kinetics of intact PTH (iPTH) after parathyroidectomy in 10 chronic hemodialysis (HD) patients who had secondary hyperparathyroidism. We determined the levels of iPTH before surgery and its evolution after parathyroidectomy at regular intervals: Day 0, D7, D15, D30 and D90. The mean age of our patients was 40 ± 13 years, with a sex ratio of 1. The mean duration on HD was 122 ± 63 months. The duration of secondary hyperparathyroidism varied from one year to 12 years. All patients had received medical treatment for hyperparathyroidism. The indications for parathyroidectomy included resistance to medical treatment in seven cases, development of brown tumors in two cases and soft tissue calcifications in one case. All patients had radiographic evidence of hyperparathyroidism. The parathyroidectomy was sub-total in all patients, 6/8 in four cases and 7/8 in six cases. The mean iPTH level was 2341 ± 1946 pg/mL before surgery. A sharp drop in this level was noticed on D0, with a median of 92 pg/mL and, thereafter, the levels were 79 pg/mL on D7, 25 pg/mL on D15 and 36 pg/mL after 1 month. At 3 months post-surgery, the mean iPTH level was 302 pg/mL. Histological examination of the resected gland showed parathyroid hyperplasia in all patients. In our series, the efficacy of sub-total parathyroidectomy was satisfactory with rapid normalization of PTH, which is consistent with the literature data. Sub-total parathyroidectomy still has a place in the treatment of secondary hyperparathyroidism in chronic renal failure. Its indications should be limited to cases resistant to medical treatment and, in particular, in cases with occurrence of complications. PMID:26586059

    In this study, we characterized cerebral blood flow changes by assessment of blood flow parameters in neck arteries using carotid duplex ultrasonography and predictive factors for these hemodynamic changes. Hemodynamic variables were measured before and during hemodialysis in 81 patients with an arteriovenous access in their arm. Hemodialysis produced significant lowering in peak systolic velocity and flow volume of neck arteries and calculated total cerebral blood flow (1,221.9 ± 344.9 [before hemodialysis] vs. 1,085.8 ± 319.2 [during hemodialysis], P < 0.001). Effects were greater in vessels on the same side as the arteriovenous access and these changes were influenced by arteriovenous access flow during hemodialysis, both in the CCA (r = -0.277, P = 0.015) and the VA (r = -0.239, P = 0.034). The change of total cerebral blood flow during hemodialysis was independently related with age, presence of diabetes, and systemic blood pressure. PMID:27478334

    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.

    Gastric cancer (GC) is one of the most frequent malignant diseases in the elderly. Systemic chemotherapy showed an improvement of quality of life and survival benefit compared to supportive care alone in patients with advanced GC. Because comorbidities or age-related changes in pharmacokinetics and pharmacodynamics may lead to higher toxicity, however, many oncologists hesitate to recommend elderly patients to receive chemotherapy. Available data suggest that elderly patients with GC are able to tolerate and benefit from systemic chemotherapy to the same extent as younger patients. The age alone should not be the only criteria to preclude effective chemotherapy. However, proper patient selection is extremely important to deliver effective treatment safely. A comprehensive geriatric assessment (CGA) is a useful method to assess life expectancy and risk of morbidity in older patients and to guide providing optimal treatment. Treatment should be personalized based on the nature of the disease, the life expectancy, the risk of complication, and the patient's preference. Combination chemotherapy can be considered for older patients with metastatic GC who are classified as non-frail patients by CGA. For frail or vulnerable patients, however, monotherapy or only symptomatic treatment may be desirable. Targeted agents seem to be promising treatment options for elderly patients with GC considering their better efficacy and less toxicity. PMID:26722364

    Retention of {beta} 2-microglobulin in patients undergoing hemodialysis is associated with a {beta} 2-microglobulin-derived amyloidosis. Removal of {beta} 2-microglobulin by renal replacement therapy has been proposed for the prevention of this amyloidosis. Currently, however, data on the {beta} 2-microglobulin synthesis rate in patients undergoing hemodialysis are scarce, and consequently it remains speculative how much removal would be necessary to counterbalance synthesis. The plasma kinetics of iodine 131-labeled {beta} 2-microglobulin were therefore examined in 11 patients with anuria who were undergoing long-term hemodialysis. Five healthy persons served as controls. Kinetic modeling of the plasma curves showed that the data fitted a two-pool model (r2 greater than 0.96) consisting of a rapid 2 to 4 hour distribution phase followed by a less steep curve, described by the plasma (metabolic) clearance (Clp). Synthetic rates were calculated from Clp and the {beta} 2-microglobulin steady state plasma concentration (plus {beta} 2-microglobulin removal during hemodialysis in the case of high flux hemodialysis). The results showed a significantly higher Clp in normal controls as compared with patients undergoing hemodialysis (65.5 {plus minus} 12.8 ml/min (mean {plus minus} SD) versus 3.4 {plus minus} 0.7 ml/min). In contrast, the {beta} 2-microglobulin synthesis rate in the patient group (3.10 {plus minus} 0.79 mg/kg/day) was not significantly different from that of normal controls (2.40 {plus minus} 0.67 mg/kg/day), which was due to markedly elevated {beta} 2-microglobulin plasma concentrations in the patients (37.6 {plus minus} 14.1 mg/L vs 1.92 {plus minus} 0.27 mg/L). These findings suggest that the presence of end-stage renal disease does not have a significant impact on the beta 2-microglobulin generation rate.

    Takotsubo cardiomyopathy is a disorder characterized by left ventricular apical ballooning and electrocardiographic changes in the absence of coronary artery disease. While reversible in many cases, the mechanism of this disorder remains unclear. The most frequent clinical symptoms of takotsubo cardiomyopathy on admission are chest pain and dyspnea, resembling acute myocardial infarction. Here, we describe two cases of takotsubo cardiomyopathy without chest pain or dyspnea in patients on maintenance hemodialysis. The asymptomatic nature of these two cases may be due to the patients being on hemodialysis. Periodic electrocardiograms (ECG) may be helpful in screening this population for asymptomatic takotsubo cardiomyopathy and in evaluating its incidence. PMID:24527248

    Prosthetic arteriovenous (AV) graft is the second most common vascular access of choice in hemodialysis patients. Rare complications of such grafts are increasingly seen due to rising population of patients on hemodialysis. Infections and thrombosis are the most common complications. Though metallic implants are known to cause hypersensitivity skin reactions, prosthetic AV grafts are rarely known to cause such kind of reactions due to inert nature of materials used in their preparation. We present a case of 54-year-old male who developed contact dermatitis after AV graft creation which was mistreated initially as infection. PMID:27493977

    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

    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.

    The treatment for elderly patients affected by glioblastoma represents a challenge in neuro-oncology. The recent randomized trials (the NOA-8 and the NCBTSG trials) showed an advantage of temozolomide for patients with O6-methylguanine methyltransferase methylated tumors. To date, no randomized trials compared the standard treatment (radiochemotherapy) with other therapeutic approaches, due to the idea that elderly patients do not tolerate aggressive therapy. Nonetheless, with the increased lifespan and the better quality of life, the nihilism in the treatment of elderly with cancer is obsolete. Molecular (including O6-methylguanine methyltransferase) and clinical tools (including the geriatric evaluation) are needed for choosing the proper therapy for patients over 70. PMID:24117272

    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.

    Restless legs syndrome (RLS) is a common neurologic sensorimotor disorder. It is also seen in hemodialysis patients in whom the mechanism is not thoroughly understood. The aim of this study was to evaluate the association between malnutrition-inflammation score (MIS), sleep quality, and RLS in chronic hemodialysis patients. This cross-sectional study included 232 adult stable chronic hemodialysis patients (mean age 60.9 ± 14.1 years, 56.5% male). RLS frequency, MIS, Pittsburgh Sleep Quality Index (PSQI), laboratory data of patients as well as severity of RLS were evaluated. Thirty-seven patients (15.9%) were diagnosed with RLS. Mean MIS of patients with or without RLS were similar. PSQI of patients with RLS was significantly higher than patients without RLS (P = 0.002). There was a significant positive correlation between RLS severity and PSQI (r = 0.445, P = 0.006). A significant positive correlation was also found between PSQI and MIS in patients with RLS (r = 0.419, P = 0.010). RLS severity was positively correlated with some inflammatory parameters such as white blood cell count and C-reactive protein (r = 0.427, P = 0.008 and r = 0.418 P = 0.010). PSQI was found as an independent significant predictor of RLS (odds ratio [OR] = 1.15 (1.06-1.25), P = 0.001) in multivariate logistic regression analysis. Our study revealed that there was no significant relationship between RLS and MIS in chronic hemodialysis patients. However, RLS severity is correlated with inflammatory parameters. Also, sleep quality in chronic hemodialysis patients with RLS is negatively associated with MIS. PMID:26031339

    Background: Hemodialysis patients have a high physical and psychosocial symptom burden. There is no valid and reliable tool for assessing symptoms of hemodialysis patients in Iran. Objectives: The aim of this study was to determine psychometric properties of the Persian version of the dialysis symptom index (DSI). Patients and Methods: The forward-backward procedure was applied to translate the DSI from English into Persian (Iranian language). The scale (Persian Version) was tested with a convenience sample of 95 patients with end-stage renal disease referred to main hemodialysis centers from December 2012 to June 2013. Validity was assessed using content, face and convergent validity. To test reliability, the kappa values were calculated for test-retest stability and the Cronbach alpha coefficients were also calculated for internal consistency. Results: The mean age of patients was 50.4 (SD = 15.72) years and % 61.1 of patients were male. The most commonly reported symptoms were fatigue, being irritable and nervous. Divergent validity was mostly supported by the pattern of association between DSI and SF-36 (r = -0.18– -0.48, P< 0.05). Cronbach’s alpha of the DSI was 0.90 and the weighted kappa ranged from 0.21 to 0.93, and it was greater than 0.4 for 25 of the 30 items. Conclusions: The Iranian version of the DSI had good psychometric properties and can be used to assess symptoms of hemodialysis patients. PMID:25738123

    Background: In patients with advanced renal dysfunction undergoing maintenance hemodialysis, glycated albumin (GA) levels may be more representative of blood glucose levels than hemoglobin A1C levels. The aim of this study was to determine the predictive power of GA levels on long-term survival in hemodialysis patients. Methods: A total of 176 patients with a mean age of 68.2 years were enrolled. The median duration of follow-up was 51.0 months. Receiver-operating characteristic curve analysis was utilized to determine the optimal cutoff value. We examined the cumulative survival rate by Kaplan-Meier estimates and the influence of known survival factors with the multivariate Cox proportional-hazard regression model. Results: In the whole patient group, cumulative survival in the low GA group was better than in the high GA group (p=0.030), with more prominence in those aged <70 years (p=0.029). In subgroup analysis, both diabetic (DM) and non-DM patients with low GA had a better cumulative survival compared with those with high GA. The risk of mortality increased by 3.0% for each 1% increase in serum GA level in all patients undergoing hemodialysis. Conclusions: In addition to serving as a glycemic control marker, GA levels may be useful for evaluating the risk of death in both DM and non-DM patients on hemodialysis. PMID:27226780

    Background. The aim of this study is to evaluate the usefulness of serum N-glycan profiling for prognosis in hemodialysis patients. Methods. Serum N-glycan analysis was performed in 100 hemodialysis patients in June 2008 using the glycoblotting method, which allows high-throughput, comprehensive, and quantitative N-glycan analysis. All patients were longitudinally followed up for 5 years. To evaluate the independent predictors for prognosis, patients' background, blood biochemistry, and N-glycans intensity were analyzed using Cox regression multivariate analysis. Selected N-glycans and independent factors were evaluated using the log-rank test with the Kaplan-Meier method to identify the predictive indicators for prognosis. Each patient was categorized according to the number of risk factors to evaluate the predictive potential of the risk criteria for prognosis. Results. In total, 56 N-glycan types were identified in the hemodialysis patients. Cox regression multivariate analysis showed cardiovascular events, body mass index, maximum intima media thickness, and the serum N-glycan intensity of peak number 49 were predictive indicators for overall survival. Risk classification according to the number of independent risk factors revealed significantly poor survival by increasing the number of risk factors. Conclusions. Serum N-glycan profiling may have a potential to predict prognosis in patients undergoing hemodialysis. PMID:24453820

    Aims: chronic inflammation contributes significantly to the morbidity and mortality of chronic hemodialysis patients. A recent research has shown that adipokines were associated with inflammation in these patients. We aim to investigate whether biomarkers of inflammation, adipokines, and clinical features can predict the outcome of hemodialysis patients. Materials and methods: we enrolled 181 hemodialysis patients (men: 97, mean age: 56.3±13.6) and analyzed predictors of long-term outcomes. Results: during the 3-year followup period, 41 patients died; the main causes of death were infection and cardiovascular disease. Elevated serum levels of hsCRP and albumin and advanced age were highly associated with death (all P<.001). Leptin and adiponectin levels were not significantly different between deceased patients and survivors. Cox-regression analysis indicated that age, diabetes, albumin level, and hsCRP were independent factors predicting mortality. Conclusion: the presence of underlying disease, advanced age, and markers of chronic inflammation is strongly related to survival rate in long-term hemodialysis patients. PMID:18288267

    Background: 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. Objectives: 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. Patients and Methods: 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). Results: 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. Conclusions: 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. PMID:26430525

    In elderly people, glucose tolerance is deteriorated and the incidence of diabetes mellitus is increased, due to decreased muscle mass and physical activity, declining pancreatic beta cell function, and other factors. Diabetes mellitus is an important risk factor for arteriosclerosis development in the elderly. Precise diagnosis and adequate treatment are necessary to prevent cerebrovascular and ischemic heart diseases. Elderly patients with diabetes mellitus are characteristically afflicted with more complications, impaired activities of daily living, cognitive function decline, and family environment problems, as compared with young and middle-aged diabetics. Therefore, tailor-made rather than uniform therapy becomes important. Lifestyle modification is the basis of diabetes treatment. Herein, we describe "prevention and management" of diabetes mellitus, focusing on the lifestyles of elderly diabetics.

    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 of 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.

    Background: 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. Objectives: 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. Patients and Methods: 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: 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. Conclusions: In conclusion, dietary counseling of patients on HD is mandatory.

    With the growth of the elderly population, and the female elderly population in particular, healthcare providers will see increasing numbers of elderly women with psychiatric disorders. To properly care for this group of patients, better understanding is needed not only of group differences in this patient population but also of the differences in each individual, as they age, given their unique life experiences, cohort effects, medical comorbidity, social situation, and personality traits. Understandably, these characteristics will interact with psychiatric disorders in ways that may increase the challenge to correctly diagnose and treat these patients. In addition, understanding late life changes, the prevalence of various mental disorders and the sometimes unique presentation of mental disorders in this age group is required to better diagnose and treat this population.

    Background: Patients with chronic kidney disease (CKD) experience multiple complications including erectile dysfunction (ED). It involves more than 50% of patients on dialysis or transplant. In Africa, the true extent of ED in CKD is unknown although some studies have been done in this regard. Objectives: This study aimed to determine the prevalence and identify risk factors of ED in patients on hemodialysis. Patients and Methods: This cross-sectional multicenter study was conducted from January 2, 2012 through April 30, 2012 in four hemodialysis centers in Dakar. We included all patients on chronic hemodialysis who aged ≥ 18 years old and freely consented to participate in the study. Sociodemographic, clinical, and hemodialysis data were collected through a questionnaire. Erectile function was assessed by a short version of International Index of Erectile Function (IIEF-5). Results: Among a target of 80 patients, 73 met the inclusion criteria and were included in this study. Mean dialysis vintage was 27.3 months (range, 1-156). Their mean age was 53.81 ± 12.52 years, with a higher proportion of age group of 50 to 69 years old. Fifty-six patients were married (37 monogamous and 19 polygamous) and six were singles. Overall prevalence of ED was 84.9% and it was severe in 14 patients (19.2%). Hypertension and diabetes were the most frequent etiologies and antihypertensive treatment was used in 95.5%. The main factors associated with ED were age > 50 years old and polygamy. Conclusions: ED is a common problem among patients on hemodialysis in Dakar with a high prevalence. Aging and diabetes represent most common causes. More efforts are needed for its early detection, prevention, and multidisciplinary management. PMID:25738113

    Summary Background and objectives Although limited health literacy is estimated to affect over 90 million Americans and is recognized as an important public health concern, there have been few studies examining this issue in patients with chronic kidney disease. We sought to characterize the prevalence of and associations of demographic and clinical characteristics with limited health literacy in patients receiving maintenance hemodialysis. Design, setting, participants, & measurements As part of a prospective clinical trial of symptom management strategies in 288 patients treated with chronic hemodialysis, we assessed health literacy using the Rapid Estimate of Adult Literacy in Medicine (REALM). We defined limited health literacy as a REALM score ≤60 and evaluated independent associations of demographic and baseline clinical characteristics with limited health literacy using multivariable logistic regression. Results Of the 260 patients who completed the REALM, 41 demonstrated limited health literacy. African-American race, lower educational level, and veteran status were independently associated with limited health literacy. There was no association of limited health literacy with age, gender, serologic values, dialysis adequacy, overall symptom burden, quality of life, or depression. Conclusions Limited health literacy is common among patients receiving chronic hemodialysis. African-American race and socioeconomic factors are strong independent predictors of limited health literacy. These findings can help inform the design and implementation of interventions to improve health literacy in the hemodialysis population. PMID:21551025

    Background The restless legs syndrome is a sensorimotor disorder that is very common in patients on hemodialysis. Due to pharmacological treatments which have their own side effects, nowadays, studies have turned to non-pharmacological treatments. Objectives The present study aims to assess the effect of stretching exercises on the severity of restless legs syndrome in patients on hemodialysis. Patients and Methods This clinical trial study was conducted on 33 patients who had been identified using diagnostic criteria from the hemodialysis ward of Hasheminejad Hospital in Tehran. Participants were randomly divided into the intervention group (n = 17) and control group (n = 16). Stretching exercises were performed on legs during the dialysis for half an hour, three times a week for 8 weeks in intervention group. Data were collected by using the international restless legs syndrome study group scale. Results The results showed that the majority of participants were suffering from moderate restless legs syndrome. The symptom severity of this syndrome meaningfully changed eight weeks after intervention in the intervention group compared to the control group (P < 0.001). Conclusions The results highlighted the significance of training and performing the stretching exercises during dialysis for the purpose of improving restless legs syndrome symptoms and the quality of care of hemodialysis patients.

    INTRODUCTION. Oxidative stress in patients with chronic kidney failure, particularly in hemodialysis patients, has been suggested to have a major role in the pathogenesis of atherosclerosis. We evaluated omega-3 fatty acids supplementation effects on oxidative and antioxidant factors in hemodialysis patients. MATERIALS AND METHODS. In a clinical trial, patients on hemodialysis were divided into 2 groups in order to receive either omega-3 fatty aid capsule, 1 g 3 times a day, or placebo for 2 months. The two groups were comparable in terms of sex distribution, age, medications, diabetes mellitus, hemoglobin level, serum ferritin, and serum albumin. Blood samples taken from patients before and at the end of the study period were examined for oxidative stress markers including malondialdehyde, glutathione peroxidase, superoxide dismutase, and ferric reducing antioxidant power. RESULTS. Seventy-five hemodialysis patients were divided into the omega-3 group (n = 37) and the control group (n = 38). Before the treatment period, the two groups were comparable in the malondialdehyde, glutathione peroxidase, superoxide dismutase, and ferric reducing antioxidant power levels. In the patients who received omega-3 fatty acids, antioxidant factors including glutathione peroxidase, superoxide dismutase, and ferric reducing antioxidant power were significantly increased after two months (P = .02, P = .02, and P = .01, respectively); however, there was no significant changes in the control group in these markers. Malondialdehyde levels were significantly reduced after the study period only in the omega-3 group (P = .007). CONCLUSIONS. The present study revealed that the supplementation with omega-3 fatty acids may result in better antioxidation status in patients on maintenance hemodialysis.

    Zidovudine (azidothymidine, AZT) disposition was examined during a hemodialysis session in an HIV-infected male with mesangial proliferative glomerulonephritis. Serum concentrations of zidovudine and its glucuronidated inactive metabolite (G-ZDV) were measured by HPLC. Zidovudine pharmacokinetics were similar to previous reports in patients with normal renal function, however, G-ZDV concentrations were significantly elevated (23-440 times zidovudine concentration). Hemodialysis did not appreciably reduce zidovudine or G-ZDV levels. Significance of chronically elevated G-ZDV levels is unknown.

    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 methylenetetrahydrofolate reductase (MTHFR) gene polymorphism, apolipoprotein E (apo epsilon4) gene polymorphism and polymorphism of plasminogen activator inhibitor-1 (PAI-1) have been shown to be associated with end-stage renal disease (ESRD). To determine the prevalence of these mutations in Saudi patients with ESRD on hemodialysis, we studied the allelic frequency and genotype distribution in patients receiving hemodialysis and in a control group, all residing in the Eastern Province of Saudi Arabia. The genotypes were determined using allele specific hybridization procedures and were confirmed by restriction fragment length polymorphism. The T allele frequency and homozygous genotype of MTHFR in ESRD patients were 14% and 2.4%, respectively compared to 13.4% and 0%, respectively in the control group. The allele frequency and homozygous genotype of 4G/4G PAI-1 gene polymorphism were 46.4% and 4.8% respectively in ESRD patients compared to 57.1% and 32% respectively in the control group. The apo s4 allele frequency and homozygous genotype distribution in hemodialysis patients were 7% and 2.4%, respectively compared to 13% and 2% in the control group. Although allele frequency of C677T of MTHFR was statistically similar in the hemodialysis patients and in the control group, the homozygotes T allele genotype was over represented in the hemodialysis group compared to normal. The prevalence of PAI-1 4G/4G polymorphism in ESRD patients was lower when compared to the control group. The prevalence of apo s4 allele did not differ significantly between the two groups. The present results demonstrate that all three studied polymorphic mutations are present in our population and that they may contribute to the etiology of the disease in our area. PMID:18974580

    Summary Background and objectives Peginesatide (Omontys) is a novel, synthetic, PEGylated, peptide-based erythropoiesis-stimulating agent (ESA) that is designed to specifically stimulate the erythropoietin receptor. This study evaluated maintenance of hemoglobin levels in patients after conversion from darbepoetin alfa to once-monthly peginesatide. Design, setting, participants, & measurements This open-label, multicenter study included 101 CKD patients, 52 of whom were receiving dialysis. The duration of the study was 24 weeks. The primary endpoint was the mean change in hemoglobin from baseline to the evaluation period (weeks 19–24). The study was conducted during the period from September 22, 2008 to December 24, 2009. Results The mean change among hemodialysis patients was –0.42 g/dl (95% confidence interval, –0.65 to –0.19) and the mean change among CKD nondialysis patients was 0.49 g/dl (95% confidence interval, 0.26–0.71). The percentages of patients who maintained hemoglobin levels within ±1.0 g/dl of baseline values were as follows: 80.0% for hemodialysis and 68.1% for nondialysis, and73.3% for hemodialysis and 68.1% for nondialysis within the target range of 10.0–12.0 g/dl. Few patients received red blood cell transfusions (hemodialysis, 5.8%; nondialysis, 2.0%). Seventy-nine patients experienced adverse events, the majority of which were mild or moderate in severity. There were 40 serious adverse events and 2 deaths reported. Conclusions In this study, once-monthly peginesatide resulted in a slight decrease in mean hemoglobin levels in individuals on hemodialysis and a small increase in individuals with CKD who were not on dialysis.

    Annual influenza vaccination is recommended, but its efficacy in dialysis population is still controversial. Here we aimed to compare the dynamic changes of immune response between various influenza vaccination protocols in hemodialysis patients. A 18-week open label, non-randomized, controlled trial was conducted during 2011–2012. The efficacy between unvaccinated, one- and two-dose regimens were evaluated in 175 hemodialysis patients. Immunogenic profiles were assessed by hemagglutination-inhibition assays. At 3–9 weeks post-vaccination, antibody responses were similar between the one- and two-dose regimens, while the seroprotection rates (antibody titer ≥1:40) for influenza A were 55.6–82.5% in the adult (18–60 years) and 33.3–66.7% in the elderly (>60 years). Meanwhile, the seroprotection rates for influenza B were low (4.0–25.0%). By 18 weeks post-vaccination, the seroprotection rates for influenza A and B declined (0.0–33.3%) in both the adult and elderly receiving one- or two-dose regimens. Of dialysis patients, at most 2.4% developed moderate to severe adverse effects(myalgia and headache) after vaccination. In conclusion, the two-dose regimen could not improve immune responses than the one-dose regimen in hemodialysis patients; meanwhile the induced protective antibodies of both regimens could not be maintained for more than 4 months. Modification of current influenza vaccination strategy in dialysis population should be re-considered. PMID:26869526

    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.

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

    PubMed

    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.

    Half of all cancers occur in patients older than 70 years. National cancer plans in France promote the emergence of geriatric oncology, whose aim is that every elder cancer patient receives a pertinent treatment, according to his frailty. Geriatric intervention has been evaluated in various conditions or patients since 30 years. Meta-analysis has shown the benefits on autonomy and mortality. But benefits are related to the organization of geriatric care, especially when integrated care is provided. Literature on geriatric oncology is relatively poor. But it is certain that a geriatric comprehensive assessment provided a lot of important information for the care of cancer patients, leading to a modification of cancer treatment in many cases. Randomized trials will soon begin to evaluate the benefits of geriatric integrated care for elder cancer patients, in terms of mortality and quality of life. Actually, in oncogeriatic coordination units, pilot organizations are developed for the satisfaction of patients and professionals.

  20. Obese and diabetic patients with end-stage renal disease: Peritoneal dialysis or hemodialysis?

    2016-07-01

    Obesity is a chronic disease that is increasingly prevalent around the world and is a well-recognized risk factor for type 2 diabetes and hypertension, leading causes of end-stage renal disease (ESRD). The obese diabetic patient with ESRD is a challenge for the nephrologist with regard to the type of renal replacement therapy that should be suggested and offered to the patient. There is no evidence that either peritoneal dialysis or hemodialysis is contraindicated in obese ESRD patients. In the literature, we can find a discrepancy in the impact of obesity on mortality among hemodialysis vs. peritoneal dialysis patients. Several studies in hemodialysis patients suggest that a higher BMI confers a survival advantage - the so-called "reverse epidemiology". In contrast, the literature among obese peritoneal dialysis patients is inconsistent, with various studies reporting an increased risk of death, no difference, or a decreased risk of death. Many of these studies only spanned across a few years, and this is probably too short of a time frame for a realistic assessment of obesity's impact on mortality in ESRD patients. The decision for dialysis modality in an obese diabetic patient with ESRD should be individualized. According to the results of published studies, we cannot suggest PD or HD as a better solution for all obese diabetic patients. The obese patient should be educated about all their dialysis options, including home dialysis therapies. In this review, the available literature related to the dialysis modality in obese patients with diabetes and ESRD was reviewed.

    In recent years, many patients have had to undergo hemodialysis due to chronic renal failure. In addition, the number of hemodialysis patients in whom lung cancer is discovered is increasing. However, a standard chemoradiotherapy regimen for limited-disease small-cell lung cancer patients undergoing maintenance hemodialysis has not yet been established. We administered concurrent chemoradiotherapy using carboplatin 300 mg/m2 (day 1) plus etoposide 50 mg/m2 (day 1, 3). A partial response was achieved after 4 courses of chemotherapy and 68 Gy of radiotherapy. The major toxicities were hematological toxicities; they included grade 4 thrombocytopenia, grade 3 anemia, and neutropenia. PMID:26809534

    INTRODUCTION. Treatment modalities for end-stage renal disease affect quality of life (QOL) of the patients. This study was conducted to assess the QOL of patients on hemodialysis and compare it with caregivers of these patients. Cause of ESRD and dialysis-related factors affecting QOL were also examined. MATERIALS AND METHODS. This cross-sectional study was conducted on patient on maintenance hemodialysis for more than 3 months at 3 dialysis centers of Lahore. Fifty healthy individuals were included as controls from among the patients' caregivers. The QOL index was measured using the World Health Organization QOL questionnaire, with higher scores corresponding to better QOL of patients. RESULTS. Eighty-nine patients (71.2%) were men, 99 (79.2%) were married, 75 (60.0%) were older than 45 years, and 77 (61.6%) were on dialysis for more than 8 months. Patients on hemodialysis had a poorer QOL as compared to their caregivers in all domains except for domain 4 (environment). There was no difference in the QOL between the three dialysis centers of the study, except for domain 3 (social relationship) of the patients at Mayo Hospital (a public hospital), which was significantly better. Nondiabetic patients had a better QOL in domain 1 (physical health) as compared to diabetic patients. Duration of dialysis had a reverse correlation with the overall QOL. CONCLUSIONS. We found that QOL of hemodialysis patients was poor as compared to caregivers of the patients, especially that of diabetics. Also, duration of dialysis had a reverse correlation with QOL.

    Aims We sought to explore the response of the corrected QT (QTc) interval duration and QT dispersion (QTD) to hemodialysis. Methods We enrolled 50 patients with end-stage renal disease undergoing regular hemodialysis. Blood samples were drawn for measurement of serum electrolytes, and a 12-lead ECG was performed to measure the QTc interval duration and QTD, immediately before and just after dialysis sessions. Results The mean age of the cohort was 42.8 ± 12.2 years (58% males). Both the QTc duration and QTD showed marked variability after hemodialysis. A significant correlation was found between the decrease of both serum potassium and magnesium levels after dialysis and the post-dialysis QTc interval duration, with Pearson's correlation coefficients r = −0.43 and r = −0.34, p = 0.002 and p = 0.01, respectively. Patients with a post-dialysis increase of QTc interval duration had a significantly higher percentage of reduction of serum potassium (p = 0.029), whereas patients with a post-dialysis increase of QTD had a significantly higher percentage of reduction of serum magnesium (p = 0.03). Conclusion Our findings suggest a highly variable response of the QTc interval duration and QTD to hemodialysis. The post-dialysis QTc interval duration inversely correlated with the decrease of both serum potassium and magnesium levels after dialysis. PMID:22470374

    The adverse effects of increased blood lead levels have been well discussed. Several antioxidant agents have been reported to offer protection from lead toxicity and to reduce blood lead levels (BLL). Given that erythropoietin (EPO) also has antioxidant properties, the aim of this cross-sectional study was to assess the role of EPO and other clinical variables on BLL in hemodialysis (HD) patients. We recruited 931 maintenance hemodialysis (MHD) patients who had undergone HD for at least 6 months and who had ever received blood lead level (BLL) study. Use of erythropoiesis-stimulating agents followed the The National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF KDOQI) Clinical Practice Guideline. We estimated demographic, hematological, nutritional, inflammatory, biochemical, and dialysis-related data based on this study. In the group with EPO, 7% had high BLL. In the group without EPO, 22% had high BLL. From the stepwise liner regression, urban areas, hemodialysis duration, and clearance of urea (KT/Vurea) were positively associated with log BLL. In contrast, diabetes (DM), and monthly EPO dose were negatively associated with log BLL. This study showed that EPO dose might be negatively associated with blood lead levels in patients on maintenance hemodialysis. PMID:27680289

    Objective To assess whether use of folic acid vitamin supplements reduces cardiac and stroke mortality in hemodialysis patients. Further, we examined whether consumption of folic acid from vitamin supplements greater than 1000 μg compared to standard 1000 μg, and 1000 μg compared to either lower dose or no consumption were associated with reduced cardiac and stroke mortality risk. Design Secondary analysis of data from the Hemodialysis (HEMO) Study, a randomized clinical trial examining dialysis treatment regimens over three years follow-up. Participants: One thousand eight hundred and forty-six hemodialysis patients previously participating in the HEMO study. Interventions None Main Outcome Measure Cardiac and stroke mortality. Results From time-dependent Cox proportional hazard regression models, folic acid consumption from vitamin supplements, above or below the standard 1000 μg dose was not associated with decrease or increase in cardiac mortality (P = 0.53 above vs. standard dose and P = 0.46, below vs. standard dose). There was also no association between folic acid consumption and mortality from stroke (P = 0.27, above vs. standard dose and P = 0.64, below vs. standard dose). Conclusion Consumption of higher than the standard 1000 μg prescribed dose of folic acid was not beneficial in reducing cardiac or stroke mortality in hemodialysis patients. Similarly, consumption of lower than standard dose was not associated with an increase in either cardiac or stroke mortality. PMID:20303789

    Deficiency of essential trace elements (such as Cu or Zn) and accumulation of potentially toxic trace elements (as Cd or Pb) are both known to have adverse effects in hemodialysis (HD) patients. Up to our knowledge, no studies about the permeability of low and high flux polysulfone membranes on metal ions during hemodialysis are available. Therefore, the aim of the present study was to address this issue. Forty one hemodialysis patients (19 were using high flux polysulfone membrane while the remaining were using low flux one) participated in the study. Blood levels of Cu, Zn, Cd and Pb were determined by graphite furnace atomic absorption spectrometry among HD patients, before and after dialysis session, as well as among matched 40 healthy persons. Blood concentrations of Cu and Zn in the whole hemodialysis group was significantly lower than those of the healthy control group, on the other hand the toxic metals (Cd and Pb) levels were observed to be significantly higher among HD patients compared to the normal persons. Among the hemodialysis group, there were no significant differences between the low and high flux dialyzer groups in terms of pre-dialysis blood levels of Cu, Zn, Cd and Pb. In addition, significantly decreased levels of all metal ions were observed after dialysis sessions using either low or high flux membranes. An exception was Pb which did not show any difference between pre-dialysis and post-dialysis values in the low flux groupIn conclusion Zn and Cu deficiencies should be considered in the treatment of these patients. High flux membranes are more efficient than low flux ones in removing excess Cd and Pb. Therefore, when high flux membranes are used, chelation therapy might not be required for Cd and Pb overload.

    A bone biopsy specimen in a long-term hemodialysis patient with sarcoidosis coexisting with severe hypoparathyroidism has demonstrated that a persistent near physiological level of 1,25-dihydroxyvitamin D3 contributes to the preservation of bone remodeling and has the potential to retard the development of vascular calcification and atherosclerosis. Sarcoidosis-related hypercalcemia and hypoparathyroidism, which is characterized by 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) overproduction, is rarely seen in hemodialysis patients. Herein, we describe a 60-year-old Japanese woman on hemodialysis for 35 years who presented with malaise and hypercalcemia. Severe hypoparathyroidism without parathyroidectomy and a preserved 1,25(OH)2D3 level were detected. Computed tomography showed bilateral axillary lymphadenopathy and minimal aortic and soft tissue calcification. The axillary node biopsy led to a definite diagnosis of sarcoidosis. A bone biopsy specimen obtained from the right iliac crest showed remodeling of normal lamellar bone with scalloped cement lines and clear double labeling by tetracycline on fluorescence microscopy. Histomorphometric analysis revealed that the bone formation rate was preserved (30.0 %/year), together with a decrease of osteoid volume (5.75 %) and fibrous volume (0 %), indicating that the patient did not have adynamic bone disease and only showed mild disease. This is the first documented case of sarcoidosis-related hypercalcemia associated with severe hypoparathyroidism in a long-term hemodialysis patient who underwent bone histomorphometry. Our findings suggest that, in hemodialysis patients with sarcoidosis coexisting with severe hypoparathyroidism, a persistent near physiological level of 1,25(OH)2D3 contributes to the preservation of bone remodeling and has the potential to retard the development of vascular calcification and atherosclerosis.

    Background and objectives Telomeric G-tails play a pivotal role in maintaining the intramolecular loop structure of telomeres. Previous in vitro studies have suggested that the erosion of telomeric G-tails triggers cellular senescence, leading to organ dysfunction and atherosclerosis. The authors recently established a method to measure telomeric G-tail length using a hybridization protection assay. Using this method, this study investigated whether telomeric G-tail length could be used as a novel predictor for future cardiovascular events in hemodialysis patients. Design, setting, participants, & measurements A prospective observational study was performed involving a cohort of 203 Japanese hemodialysis patients to examine the lengths of telomeric G-tails and total telomeres and subsequent cardiovascular events during a median follow-up period of 48 months. The lengths of telomeric G-tails and total telomeres were also measured in 203 participants who did not have CKD and who were age- and sex-matched to hemodialysis patients. Results The lengths of telomeric G-tails and total telomeres were significantly shorter in hemodialysis patients than in control subjects. Telomeric G-tails, but not total telomeres, were independently and negatively associated with clinical history of cardiovascular disease. During follow-up, 80 cardiovascular events occurred. Total telomere length did not predict cardiovascular events. However, the length of telomeric G-tails was associated with new-onset cardiovascular events (hazard ratio per log luminescence signals, 0.12; 95% confidence interval, 0.12 to 0.50) that persisted after adjustment for age, sex, diabetes mellitus, clinical history of cardiovascular disease, inflammation, use of vitamin D, and serum levels of phosphate and intact parathyroid hormone. Conclusions Longer telomeric G-tail length is associated with a lower risk of future cardiovascular events in hemodialysis patients. PMID:25237070

    In the last years, the number of total hip arthroplasty is increased both in young patients and elderly with a poor bone quality due to extension of surgical indications. According to this trend, also revision surgery showed a growth of its number, especially in elderly patients, because of implant loosening, failed osseointegration of prosthetic components, errors in biomechanical restoration and infections. The aim of this study is to analyze life quality improvement through evaluation of articular functionality and postoperative pain, and to examine osseointegration of implant components with periprosthetic bone. During total hip arthroplasty revision, the orthopedic surgeon often has to face complex cases, especially in elderly patients with a preexisting status of poor bone quality and sarcopenia. In these cases, a correct planning and a surgical procedure well-executed are able to ensure a good outcome that led to pain relief and functional recovery. Furthermore anti-osteoporotic therapy surely represents a useful resource both in primary total hip arthroplasty and in revisions, mainly for elderly patients with a poor bone quality. PMID:24046034

    Elderly dental patients often complain of mouth dryness. This complaint is most often caused by xerogenic medications or, less often, by systemic diseases. Aging per se has no significant clinical impact on salivary gland output. Salivary gland hypofunction, whether caused by medications or systemic disorders, have a strong negative impact on intraoral tissues, with a significant reduction in the quality of life.

    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

    In 1998, data from the Assurance Maladie (national health insurance) showed that 11.2% of people over 65 years old, and thus corresponding to the World Health Organisation's definition of being elderly, were diabetic. More recently the Entred trial, a national sample representative of diabetics, clarified the characteristics, the state of health and the medical management of diabetes in patients aged over 65 years. Among the randomly selected 10,000 adults in this study, 5350 subjects (54% of the Entred population) were over 65 years old. Other studies indicate that more than a million subjects aged over 65 years are diabetic and that 25% of diabetics are aged over 75 years. The growing proportion of elderly people in the French population, plus the improvement in the detection and the better management of diabetes are bound to contribute to a further increase in the prevalence of diabetes in elderly subjects.

    When the kidney is seriously impaired, various uremic toxins (UTs) accumulate in the body, often exerting unfavorable effects on physiological functions and drug pharmacokinetics. To prevent this, it is important to determine plasma UT levels accurately in chronic kidney disease patients. Although attempts to predict plasma UT levels using biomarkers have been made, the correlation between UT levels and the markers is not yet fully understood. In this study, we assessed the correlations among plasma levels of indoxyl sulfate (IS), indoleacetic acid (IA), and 3-carboxy-4-methyl-5-propyl-2-furanpropionic acid (CMPF) in 20 hemodialysis patients and evaluated the relationship between the plasma levels of UTs and clinical parameters, such as serum creatinine (Scr), blood urea nitrogen, and estimated glomerular filtration rate (eGFR), with special focus on IS. There were no correlations among the plasma levels of the three UTs before and immediately after hemodialysis. However, a significant correlation was observed between plasma IS levels and Scr before hemodialysis (r=0.643, p=0.002), with the correlation becoming much stronger when using the data obtained immediately after hemodialysis (r=0.744, p<0.001). Further, plasma IS levels showed a significant negative correlation with eGFR (r=-0.558, p=0.011). However, no correlations were observed for IA or CMPF. The results obtained from this study suggest that plasma IS levels can be predicted from Scr values, although the precise mechanism behind the correlation remains to be clarified. PMID:27477735

    Background. Previous observations found a high prevalence of obstructive sleep apnea (OSA) in the hemodialysis population, but the best diagnostic approach remains undefined. We assessed OSA prevalence and performance of available screening tools to propose a specific diagnostic algorithm. Methods. 104 patients from 6 Swiss hemodialysis centers underwent polygraphy and completed 3 OSA screening scores: STOP-BANG, Berlin's Questionnaire, and Adjusted Neck Circumference. The OSA predictors were identified on a derivation population and used to develop the diagnostic algorithm, which was validated on an independent population. Results. We found 56% OSA prevalence (AHI ≥ 15/h), which was largely underdiagnosed. Screening scores showed poor performance for OSA screening (ROC areas 0.538 [SE 0.093] to 0.655 [SE 0.083]). Age, neck circumference, and time on renal replacement therapy were the best predictors of OSA and were used to develop a screening algorithm, with higher discriminatory performance than classical screening tools (ROC area 0.831 [0.066]). Conclusions. Our study confirms the high OSA prevalence and highlights the low diagnosis rate of this treatable cardiovascular risk factor in the hemodialysis population. Considering the poor performance of OSA screening tools, we propose and validate a specific algorithm to identify hemodialysis patients at risk for OSA for whom further sleep investigations should be considered.

    Introduction and Aim: 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. Method and material: 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. Result: According to the results, Paired t-test showed a significant difference between the mean self-esteem score in both groups before and after intervention. Conclusion: 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. PMID:26383201

    We report a case of cholesterin granuloma of the kidney masquerading as a renal tumor. A 59-year-old man with polycystic kidney disease had been on hemodialysis for 5 years when he developed asymptomatic gross hematuria. Ultrasonography and CT scanning showed a solid mass in the right kidney and nephrectomy was performed. The resected specimen was a 2.0 x 2.0 cm yellowish solid mass. Histological examination showed a granuloma containing numerous cholesterin crystals. A renal mass containing cholesterin crystals is very rare and only one case has been reported previously in Japan.

    Oropharyngeal candidiasis is a common opportunistic infection of the oral cavity caused by an overgrowth of candida species, the commonest being Candida albicans. The prevalence in the hospital or institution varies from 13 to 47% of elderly persons. The main clinical types are denture stomatitis, acute atrophic glossitis, thrush and angular cheilitis. Diagnosis is usually made on clinical ground. Culture and sensitivity testing should be undertaken if initial therapy is unsuccessful. Predisposing factors of oral candidiasis could be local and/or systemic. Local factors include wearing dentures, impaired salivary gland function and poor oral health. Systemic factors include antibiotics and some other drugs, malnutrition, diabetes, immunosuppression and malignancies. Management involves an appropriate antifungal treatment and oral hygiene. Predisposing factors should be treated or eliminated where feasible. Oral hygiene involves cleaning the teeth and dentures. Dentures should be disinfected daily and left out overnight.

    For lack of other suitable access, 10 consecutive patients received paired hemodialysis catheters for long-term hemodialysis using a translumbar approach to the inferior vena cava (IVC). All attempts were successful. Five paired catheters were placed using the single-puncture technique, and five using the dual-puncture technique. Catheters were in place for a total of 2252 catheter days. The average duration of catheter placement was 250 days (range 30-580 days). All catheters were functioning up to the time the study was completed or the patient died. The most common complication was partial dislodgment of the catheter in 3 of 23 catheters (13%), all occurring in obese patients. One episode of retroperitoneal hemorrhage was noted in a patient having the single-access technique. There were no episodes of infection or IVC thrombosis.

    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.

    Dialysis access procedures and complications are important causes of morbidity and hospitalization for chronic hemodialysis patients. The number of complicated subjects on dialysis is increasing, and creating a successful native arteriovenous fistula for these patients is a challenge. The classic Brescia-Cimino fistula may not be the best first choice for a native vascular access. We describe the surgical technique of middle-arm fistula (MAF) for hemodialysis. A total of 112 surgical procedures were performed on 106 patients with primary unassisted 24- and 48-month patency rates of 93% and 83%, respectively, and a very low incidence of complications. Our approach was found to be a useful method in patients with comorbid factors.

    The prevalence, severity, and clinical significance of physical and emotional symptoms in patients who are on maintenance hemodialysis remain incompletely characterized. This study sought to assess symptoms and their relationship to quality of life and depression. The recently developed Dialysis Symptom Index was used to assess the presence and the severity of 30 symptoms. The Illness Effects Questionnaire and Beck Depression Inventory were used to evaluate quality of life and depression, respectively. Correlations among symptom burden, symptom severity, quality of life, and depression were assessed using Spearman correlation coefficient. A total of 162 patients from three dialysis units were enrolled. Mean age was 62 y, 48% were black, 62% were men, and 48% had diabetes. The median number of symptoms was 9.0 (interquartile range 6 to 13). Dry skin, fatigue, itching, and bone/joint pain each were reported by > or =50% of patients. Seven additional symptoms were reported by >33% of patients. Sixteen individual symptoms were described as being more than "somewhat bothersome." Overall symptom burden and severity each were correlated directly with impaired quality of life and depression. In multivariable analyses adjusting for demographic and clinical variables including depression, associations between symptoms and quality of life remained robust. Physical and emotional symptoms are prevalent, can be severe, and are correlated directly with impaired quality of life and depression in maintenance hemodialysis patients. Incorporating a standard assessment of symptoms into the care provided to maintenance hemodialysis patients may provide a means to improve quality of life in this patient population.

    Hemodialysis and kidney transplant are two treatments for renal failure, which lead to numerous changes in the patients' way of life. We have questioned ourselves on the different ways they could deal with those changes by studying the representations and the ritualisation that surrounds the sick. From 2005 to 2007, qualitative interviews, based on the method of life stories, were conducted with 35 patients with chronic renal failure in three Aquitaine's centres. The results show three main groups of representation both in pre-transplant and in post-transplant. Specific behaviours are tied to each group of representation that are beneficial or deleterious with respect to treatment or the patient's social life. We will show that, on the one hand, the patients who see the hemodialysis treatment as a traditional rite of passage cope with the situation more easily and on the other hand, we will stress that this representation is closely linked to how the patients will later accept the kidney transplant. So, we have been able to link the representations of hemodialysis patients and transplant experience. Then these results have a practical consequence for the caregivers who can use the tools of anthropology (the interview guide, analysis grid) through a program of therapeutic education, to precociously take care of patients who are likely to come up against issues after their kidney transplant.

    Neuromuscular blockade is a desirable or even essential component of general anesthesia for major surgical operations. As the population continues to age, and more operations are conducted in the elderly, due consideration must be given to neuromuscular blockade in these patients to avoid possible complications. This review considers the pharmacokinetics and pharmacodynamics of neuromuscular blockade that may be altered in the elderly. Compartment distribution, metabolism, and excretion of drugs may vary due to age-related changes in physiology, altering the duration of action with a need for reduced dosage (eg, aminosteroids). Other drugs (atracurium, cisatracurium) have more reliable duration of action and should perhaps be considered for use in the elderly. The range of interpatient variability that neuromuscular blocking drugs may exhibit is then considered and drugs with a narrower range, such as cisatracurium, may produce more predictable, and inherently safer, outcomes. Ultimately, appropriate neuromuscular monitoring should be used to guide the administration of muscle relaxants so that the risk of residual neuromuscular blockade postoperatively can be minimized. The reliability of various monitoring is considered. This paper concludes with a review of the various reversal agents, namely, anticholinesterase drugs and sugammadex, and the alterations in dosing of these that should be considered for the elderly patient.

    The purpose of this descriptive-correlational study was to describe coping strategies used by males with chronic renal failure who are dependent on hemodialysis; to describe their social networks; to describe the perceived support, conflict, and reciprocity within their interpersonal relationships; and to examine the relationships among the variables support, conflict, reciprocity, social networks, and coping strategies. Social support was conceptualized as a coping resource or source of assistance in coping with the renal illness- or hemodialysis-related stressor. The Ways of Coping questionnaire and the Interpersonal Relationship Inventory were administered to 30 participants while in hospital. Although, both problem-focused and emotion-focused forms of coping were used, participants primarily used problem-focused coping, in particular, "seeking social support". Overall, the participants perceived relatively high levels of support and moderate to high levels of reciprocity with members of their social networks. Participants experienced a moderate level of conflict in their interpersonal relationships. Both escape-avoidance and conflict were positively associated with the number of people in the household. Positive reappraisal was negatively associated with the number of close relatives. The small sample size prohibits generalizability of the results. Longitudinal studies with a larger randomly selected sample would yield insights into the long-term psychological outcomes of different coping strategies and into the bi-directional relationship of support from social network and coping in this population. Implications for nurses are discussed.

    The incidence and prevalence of elderly patients are progressively increasing in most dialysis facilities with consequent medical assistance difficulties and the need to find a suitable care unit. Particularly in this age group, the clinical assessment is often difficult and the selection criteria vary widely, not only from country to country, but also from one dialysis unit to another unit in the same area. The authors discuss some of the more complex arguments for and against dialysis in elderly patients. For some of the more difficult cases, Kantian deontology and its three ethical principles of beneficence, non-maleficence and autonomy can facilitate the decision-making process regarding the acceptance or refusal of the therapy. The central role of the patients themselves, the involvement of the family, the discussion of the individual case within the dialysis team, and the good performance of the pre-dialysis program are particularly important. In certain cases it is possible to actually discontinue the treatment, or not initiate it, by using different arguments in competent or incompetent patients. In conclusion, the difficult choice of whether to treat or turn down an elderly patient must depend exclusively on the medical clinical assessment of each case, whereas economical considerations can incorrectly influence that choice.

    OBJECTIVES: to identify adaptation problems under Roy's Model in patients undergoing hemodialysis and to correlate them with the socioeconomic and clinical aspects. METHOD: a transversal study, undertaken using a questionnaire. The sample was made up of 178 individuals. The Chi-squared and Mann-Whitney U tests were undertaken. RESULTS: the adaptation problems and the socioeconomic and clinical aspects which presented statistical associations were: Hyperkalemia and age; Edema and income; Impairment of a primary sense: touch and income; Role failure and age; Sexual dysfunction and marital status and sex; Impairment of a primary sense: vision and years of education; Intolerance to activity and years of education; Chronic pain and sex and years of education; Impaired skin integrity and age: Hypocalcemia and access; Potential for injury and age and years of education; Nutrition below the organism's requirements and age; Impairment of a primary sense: hearing and sex and kinetic evaluation of urea; Mobility in gait and/or coordination restricted, and months of hemodialysis; and, Loss of ability for self-care, and months of hemodialysis and months of illness. CONCLUSION: adaptation problems in the clientele undergoing hemodialysis can be influenced by socioeconomic/clinical data. These findings contribute to the development of the profession, fostering the nurse's reflection regarding the care. PMID:25591091

    Chronic kidney disease is a major health problem due to the significant financial burden for the healthcare system and likewise for the patient who needs the treatment. The patient's whole life situation is turned upside down with chronic kidney disease when they are confronted with the forced change to start treatment with hemodialysis. Patients with chronic kidney disease experience a lack of adequate emotional support from nurses during the transition to hemodialysis. The purpose of this study was to explore nurses' experiences of giving support to patients during the transition to hospital-bound hemodialysis. The study had a qualitative descriptive design with a content analysis approach; eight nurses from four hospitals in the south of Sweden participated. The results showed that the nurses gave threshold support with an openness and awareness of the patient's individual needs during the transition, except that there seemed to be a lack of knowledge and ability to provide emotional support. Patient support during the transition could therefore be absent. Education, at local and national levels, is needed for the nurse to be able to give professional emotional support. Further research is also desired in order to provide nurses with the tools they need to give emotional support, which is of utmost importance. PMID:24717268

    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.

    Advanced glycation end products (AGE) are significantly increased in end-stage renal disease patients and it has been suggested that AGE accumulation is related to the progression of cardiovascular disease. An autofluorescence reader non-invasively assesses AGE accumulation using skin autofluorescence under ultraviolet light. Skin autofluorescence has been reported to be an independent predictor of mortality in Caucasian hemodialysis patients. The aim of this study was to assess whether skin autofluorescence in Japanese hemodialysis patients is related to the presence of cardiovascular disease. In this cross-sectional study, patients on maintenance hemodialysis (N = 128; 59 men, 69 women) were included. AGE accumulation was assessed by skin autofluorescence using an autofluorescence reader. Associations between skin autofluorescence, cardiovascular disease, and other parameters were studied. Skin autofluorescence correlated with age (r = 0.32, P < 0.01), diabetes (r = 0.21, P = 0.02), carotid intima-media thickness (IMT) (r = 0.23, P = 0.02), high-sensitivity C-reactive protein (hsCRP) (r = 0.20, P = 0.03), and plasma pentosidine (r = 0.20, P = 0.03). Each parameter was compared in patients with and without cardiovascular disease; the gender distribution, age, carotid IMT, high-density lipoprotein cholesterol, hsCRP, and skin autofluorescence were significantly related to the presence of cardiovascular disease. Multiple logistic regression analysis identified carotid IMT (OR 6.76), hsCRP (OR 1.41), and skin autofluorescence (OR 2.29) as significant factors for the presence of cardiovascular disease. Increased skin autofluorescence was related to the presence of cardiovascular disease in Asian (non-Caucasian) hemodialysis patients, and therefore an autofluorescence reader might have the potential to be a useful assessment of cardiovascular risk in these patients.

In this cross-sectional study, patients on maintenance hemodialysis (N = 128; 59 men, 69 women) were included. AGE accumulation was assessed by skin autofluorescence using an autofluorescence reader. Associations between skin autofluorescence, cardiovascular disease, and other parameters were studied. Skin autofluorescence correlated with age (r = 0.32, P < 0.01), diabetes (r = 0.21, P = 0.02), carotid intima-media thickness (IMT) (r = 0.23, P = 0.02), high-sensitivity C-reactive protein (hsCRP) (r = 0.20, P = 0.03), and plasma pentosidine (r = 0.20, P = 0.03). Each parameter was compared in patients with and without cardiovascular disease; the gender distribution, age, carotid IMT, high-density lipoprotein cholesterol, hsCRP, and skin autofluorescence were significantly related to the presence of cardiovascular disease. Multiple logistic regression analysis identified carotid IMT (OR 6.76), hsCRP (OR 1.41), and skin autofluorescence (OR 2.29) as significant factors for the presence of cardiovascular disease. Increased skin autofluorescence was related to the presence of cardiovascular disease in Asian (non-Caucasian) hemodialysis patients, and therefore an autofluorescence reader might have the potential to be a useful assessment of cardiovascular risk in these patients.

    Little is known about the prevalence, severity, or impact of symptoms in hemodialysis patients because of the lack of a validated symptom assessment instrument. We systematically developed an index to assess physical and emotional symptom burden in this patient population. We employed four steps in the generation of this index: a review of dialysis quality-of-life instruments, three focus groups, experts' content validity assessment, and test-retest reliability measurement. Seventy-five symptoms were identified. Of these, 46 appeared in > or = 4 of the instruments/focus groups and were considered for inclusion. Twelve were grouped into other symptom constructs and experts judged four of the remaining items not to be pertinent, leaving 30 items in the new index. Overall kappa statistic was 0.48+/-0.22. These steps allowed the systematic development of a 30-item symptom assessment index for hemodialysis patients. Additional reliability and validity testing is needed prior to its widespread use.

    Patients with uremia are often immunocompromised and uremia patients undergoing maintenance dialysis are often vulnerable to uncommon infections. We report a 40-year-old man who was undergoing maintenance hemodialysis and was initially diagnosed with monomicrobal necrotizing fasciitis of the lower limbs, based on blood and pus cultures that yielded Escherichia coli. His condition improved after surgical debridement and antibiotic therapy. However, he eventually died of intracranial hemorrhage related to septic emboli. Concurrent infective endocarditis was diagnosed based on an echocardiogram that indicated vegetation in the left ventricular region. Escherichia coli-related necrotizing fasciitis and infective endocarditis is rarely seen in clinical practice. There should be a high index of suspicion for multiple infections when a hemodialysis patient presents with an uncommon infection.

    Abnormalities of cognitive function and high levels of depression incidence are characteristic of hemodialysis patients. Although previously attributed to the humoral effects of uremia, it is becoming increasingly appreciated that many elements of the overall disease state in CKD patients contribute to functional disturbances and physical brain injury. These factors range from those associated with the underlying primary diseases (cardiovascular, diabetes etc.) to those specifically associated with the requirement for dialysis (including consequences of the hemodialysis process itself). They are, however, predominantly ischemic threats to the integrity of brain tissue. These evolving insights are starting to allow nephrologists to appreciate the potential biological basis of dependency and depression in our patients, as well as develop and test new therapeutic approaches to this increasingly prevalent and important issue. This review aims to summarize the current understanding of brain injury in this setting, as well as examine recent advances being made in the modification of dialysis-associated brain injury.

    We report the case of a patient on chronic hemodialysis treatment with paroxysms of severe arterial hypertension accompanied by tachycardia, pallor, sweating and tremor. Measurement of plasma catecholamines revealed norepinephrine level of 4625 pg/mL (reference range 191-225 pg/mL), epinephrine level of 1035 pg/mL (58-76 pg/mL) and dopamine level of 148 pg/mL (50-100 pg/mL). MRI showed a left adrenal mass of 2 cm. After the patient was started on an alpha-1 adrenergic receptor blocker, she underwent a left adrenalectomy. Anatomopathological examination confirmed the diagnosis of pheochromocytoma. Although urinary testing is not possible in anuric hemodialysis patients, diagnosis of pheochromocytoma can be made through measurement of plasma free metanephrines and/or plasma catecholamines.

    Malnutrition is widely prevalent among patients on hemodialysis. Malnutrition can be estimated using a fully quantitative scoring system Subjective Global Assessment-Dialysis Malnutrition Score which is simple, reliable and dynamic. The primary objective of the study was to assess the severity of malnutrition in patients with end stage renal disease and undergoing hemodialysis in a tertiary care teaching hospital in Chennai, using Subjective Global Asses sment-Dialysis Malnutrition Score and correlate it with standard indicators of malnutrition like anthropometric and biochemical parameters of the study population by Pearson's correlation. Anthropometric assessment included height, body weight, triceps skin fold thickness, mid arm circumference, mid arm muscle circumference % and biochemical parameters included serum albumin, transferrin, ferritin, total protein, total cholesterol, blood urea nitrogen and creatinine. Based on the scores, of the 66 patients, 91% were moderately malnourished. There was a significant negative correlation between modified Subjective Global Assessment-Dialysis Malnutrition Score and anthropometric measures such as triceps skin fold thickness, mid arm circumference, mid arm muscle circumference; biochemical markers such as albumin, transferrin and ferritin. The data obtained from this study confirm that a high degree of malnutrition was prevalent in patients on hemodialysis, as shown by anthropometric assessment, biochemical markers of malnutrition and Subjective Global Assessment-Dialysis Malnutrition Score. Nutritional status as determined by Subjective Global Assessment-Dialysis Malnutrition Score is a useful and reliable index for identifying patients at risk for malnutrition and it correlates well with anthropometric and biochemical assessment. may be integrated in regular assessment of malnutrition in patients on maintenance hemodialysis.

    Background The aim of this study was to describe the experience of pediatric and young adult hemodialysis (HD) patients from a global cohort. Methods The Pediatric Investigation and Close Collaborative Consortium for Ongoing Life Outcomes for MONitoring Dialysis Outcomes (PICCOLO MONDO) study provided de-identified electronic information of 3244 patients, ages 0–30 years from 2000 to 2012 in four regions: Asia, Europe, North America and South America. The study sample was categorized into pediatric (≤18 years old) and young adult (19–30 years old) groups based on the age at dialysis initiation. Results For those with known end-stage renal disease etiology, glomerular disease was the most common diagnosis in children and young adults. Using Europe as a reference group, North America [odds ratio (OR) 2.69; CI 1.29, 5.63] and South America (OR 4.21; CI 2.32, 7.63) had the greatest mortality among young adults. North America also had higher rates of overweight, obesity, hypertension, cardiovascular disease, hospitalizations and secondary diabetes compared with all other regions. Initial catheter use was greater for North American (86.4% in pediatric patients and 75.2% in young adults) and South America (80.6% in pediatric patients and 75.9% in young adults). Catheter use at 1-year follow-up was most common in North American children (77.3%) and young adults (62.9%). Asia had the lowest rate of catheter use. For both age groups, dialysis adequacy (equilibrated Kt/V) ranged between 1.4 and 1.5. In Asia, patients in both age groups had significantly longer treatment times than in any other region. Conclusions The PICCOLO MONDO study has provided unique baseline and 1-year follow-up information on children and young adults receiving HD around the globe. This cohort has brought to light aspects of care in these age groups that warrant further investigation. PMID:26985383

    Introduction: One of the major complications in hemodialysis patients is cardiovascular disease. Lipid abnormality is an important factor in the development of cardiovascular disease. Objectives: To investigate the effect of omega-3 supplementation on serum lipid profile in hemodialysis patients. Patients and Methods: This randomized clinical trial study included 2 groups of patients: those who received omega-3 supplementation (experimental group; 30 cases) and those who received placebo (control group; 30 cases). They received these for 10 weeks and serum lipid profile (triglyceride, high-density lipoprotein [HDL-C], low-density lipoprotein [LDL-C], and total cholesterol) was assessed 2 times, first before initiating supplementation and then at the end of 10-week study period. Results: Mean (±SD) serum total cholesterol levels at the beginning was 163 (±47) mg/dL in experimental group and 143 (±25) mg/dL in control group (P> 0.05). These values decreased to 124 mg/dL and 132 mg/dL in control and experimental groups (P< 0.05). There was no significant difference of HDL-C, LDL-C, or triglyceride levels between experimental and control groups after 10 weeks of treatment. Conclusion: Omega-3 supplementation in hemodialysis patients only showed significant decrease of serum total cholesterol level, but not other lipids. PMID:26468477

    Background A reverse epidemiology of classic cardiovascular risk factors was observed in hemodialysis patients with a high comorbidity burden. We hypothesized that uric acid, a novel cardiovascular risk factor, also has an altered association with survival in these patients. Methods A retrospective study was conducted on 168 consecutive outpatient hemodialysis patients over a 6-year period. Serum uric acid, albumin levels and relevant laboratory information were recorded monthly. The disease severity was assessed using Comorbidity Index (CoI) scores. Patients were stratified into 3 groups according to their serum uric acid concentrations: group I was the lowest quintile, group II was the middle 3 quintiles and group III was the highest quintile. The risks of death were calculated utilizing a Cox regression model. Results Using group II as a reference group, the hazard ratio of group I was 2.23 [95% confidence interval (CI) 1.21–4.11, p = 0.01] and group III was 0.89 (95% CI 0.47–1.71, p = 0.74). The serum uric acid levels correlated inversely with CoI scores (r = −0.31, 95% CI −0.44 to −0.17, p < 0.0001) and positively with serum albumin levels (r = 0.35, 95% CI 0.21–0.48, p < 0.0001). Conclusion Low serum uric acid is a mortality risk factor in incident hemodialysis patients with a high comorbidity burden and hypoalbuminemia. PMID:18689987

    Background. Uremic pruritus (UP) is a common symptom in patients undergoing maintenance hemodialysis for end-stage renal disease (ESRD). Objective. To determine the clinical efficacy of auricular acupressure therapy on pruritus in hemodialysis patients and to explore possible underlying mechanisms. Methods. Patients receiving maintenance hemodialysis at a referral medical center were recruited and assigned to intervention (n = 32) and control (n = 30) groups. The intervention group underwent auricular acupressure treatment three times a week for six weeks. Auricular acupressure was not applied to patients in the control group. However, tape without Vaccaria seeds was applied to the same six auricular acupoints as the intervention group. Pruritus scores were assessed using VAS scores, and enzyme-linked immunosorbent assays (ELISA) were used to measure levels of other possible contributory biochemical factors. Results. There was a significant difference in mean VAS scores between the postintervention and control groups during follow-up (3.844 ± 1.687 versus 5.567 ± 2.285, F = 22.32, P < 0.0001). Compared to the control group, serum histamine levels in the postintervention group at the six-week follow-up had decreased significantly (F = 5.01, P = 0.0290). Conclusion. Our findings suggest that auricular acupressure may be a useful treatment in the multidisciplinary management of UP in ESRD patients. PMID:26495017

    Protein-energy malnutrition is seen in patients with advanced stages of chronic kidney disease (CKD) and is even more pronounced in patients receiving long-term hemodialysis treatment. Both entities have great impact on patient morbidity and mortality. Analysis of body composition is an integral part of nutritional assessment and includes the estimation of muscle, fat, and fat-free mass, as well as the extracellular water compartment. Clinical assessment of these compartments is difficult, and gold-standard methods such as tracer dilution, magnetic resonance imaging, and dual-energy x-ray absorptiometry are expensive, cumbersome, and rarely available. We report an ongoing study of body composition in hemodialysis patients involving deuterium and sodium bromide dilution, total body potassium counting, magnetic resonance imaging, whole-body and segmental bioimpedance spectroscopy, and anthropometry. The goals of the study are (1) to validate bioimpedance technology against gold-standard methods for assessment of the various body compartments, (2) to directly quantify visceral adipose tissue mass, a potential source of cytokine production (adipokines) promoting chronic inflammation, and to study its relation to inflammatory markers, and (3) to directly quantify visceral organ mass and to study its relation to uremia toxin generation as assessed by protein catabolic rate and resting energy expenditure. Preliminary results based on up to 40 hemodialysis patients are reported.

    In 1996 we performed tandem membrane plasma exchange-hemodialysis in a 3-year-old girl and tandem immunoadsorption-hemodialysis with citrate as the only anticoagulant in a patient with Goodpasture's syndrome. In the present study, we evaluated the feasibility, efficacy and safety of 24 tandem plasma exchange/immunoadsorption hemodialysis procedures in four different circuit setups with citrate as the only anticoagulant. In two setups, the tandem procedures were connected in series (plasma exchange hemodialysis and immunoadsorption hemodialysis), while in the other two setups they were in parallel (plasma exchange hemodialysis with independent blood circuits and plasma exchange hemodialysis with independent arterial blood lines, but with a common return line). All tandem procedures were feasible, efficient and safe. No serious side-effects were recorded. The most elegant setup was the procedure with independent, parallel blood circuits. However, serial tandem procedures provided for the elimination of citrate and normalization of electrolytes before blood was returned to the patient. PMID:27312909

    With the increasing number of elderly patients the issue of pain management for older people is of increasing relevance. The alterations with aging of the neurobiology of pain have impacts of pain threshold, tolerance and treatment. In this review the available evidence from animal and human experimentation is discussed to highlight the differences between young and older subjects along with consideration of how these changes have practical effect on drug treatment of pain. Cognitive impairment, physical disability and social isolation can also impact on the accessibility of treatment and have to be considered along with the biological changes with ageing. Conventional pain therapies, while verified in younger adults cannot be automatically applied to the elderly without consideration of all these factors and in no other group of patients is a holistic approach to treatment more important.

    The purpose of this cross-sectional quantitative study was to identify iatrogenic nursing events involving elderly patients hospitalized in two nursing wards of a university hospital (Campinas, São Paulo, Brazil). Data was collected among 100 patient records (50 men, 50 women) using an instrument created by the authors. Data analysis was performed using descriptive statistics in addition to Mann-Whitney and Kruskal-Wallis tests. Results were significant at p < 0.05. Latrogenic events in the 26 files included: loss of intravenous site (14), pressure ulcers (8) and falls (2), among others. Reports were not detailed and failed to indicate interventions to prevent new occurrences. The findings suggest the importance of creating ways to encourage nursing professionals to accurately report iatrogenic events, as well as creating wards specifically for the elderly population.

    Introduction Routine hemodialysis is one of the preferred treatment methods in patients with chronic kidney disease. It seems that routine hemodialysis can be effective in improving sexual function in these patients. This study aimed to determine the effect of routine dialysis sessions over a six-month period on the status of sexual function in men with chronic renal failure using the International Index of Erectile Function (IIEF) questionnaire. Methods The cross-sectional study was conducted from November 2015 to November 2016 on patients with chronic renal failure who were first-time candidates for routine hemodialysis and who were referred to Imam Reza Hospital of Mashhad. All of the patients completed the IIEF questionnaire before their first hemodialysis. Afterwards, all of the patients underwent routine dialysis sessions over a six-month period and completed the IIEF questionnaire again at the end of the sixth month. The prevalence of sexual dysfunction was assessed before and after hemodialysis. The scores on the two IIEF questionnaires were compared according to five domains, i.e., erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction. The comparisons were done before and after hemodialysis using the paired-samples t-test. Statistical analyses were performed using SPSS version 19. Results The study included 30 men with a mean age of 40.2 ± 8.2. The prevalence of sexual dysfunctions in the order of their frequency was as follows: intercourse satisfaction (100%), overall satisfaction (100%), sexual desire (96.7%), orgasmic function (93.3%), and erectile function (90%). After six months of treatment with hemodialysis, the ratings of all areas of sexual dysfunction were improved significantly (p-value = 0.00 for all domains). Conclusion According to the results of this study, it seems that a six-month course of hemodialysis can improve erectile function, orgasmic function, sexual desire, intercourse

    Hip fractures are among the most common fractures in elderly people. The annual number of femoral fractures is even expected to increase because of an aging society. Due to the high number of comorbidities, there are special challenges in treating geriatric hip fracture patients, which require a multidisciplinary management. This includes surgical treatment allowing full weight bearing in the immediate postoperative period, osteoporosis treatment and falls prevention as well as an early ortho-geriatric rehabilitation program.

    The burgeoning population of older dialysis patients presents opportunities to provide personalized care. The older dialysis population has a high burden of chronic health conditions, decrements in quality of life and a high risk of death. In order to address these challenges, this review will recommend routinely establishing prognosis through the use of prediction instruments and communicating these findings to older patients. The challenges to prognosis in adults with end-stage renal disease (ESRD) include the subjective nature of clinical judgment, application of appropriate prognostic tools and communication of findings to patients and caregivers. There are three reasons why we believe these conversations occur infrequently with the dialysis population. First, there have previously been no clinically practical instruments to identify individuals undergoing maintenance hemodialysis (HD) who are at highest risk for death. Second, nephrologists have not been trained to have conversations about prognosis and end-of-life care. Third, other than hospitalizations and accrual of new diagnoses, there are no natural milestone guidelines in place for patients supported by dialysis. The prognosis can be used in shared decision-making to establish goals of care, limits on dialysis support or parameters for withdrawal from dialysis. As older adults with ESRD benefit from kidney transplantation, prognosis can also be used to determine who should be referred for evaluation by a kidney transplant team. The use of prognosis in older adults may determine approaches to optimize well-being and personalize care among older adults ranging from hospice to kidney transplantation.

    Introduction A new form of hepatitis C virus infection, known as occult hepatitis C virus (HCV) infection, is characterized by the presence of HCV_RNA in the liver or peripheral blood mononuclear cells (PBMCs). However, no serological markers of infection occur and there is not as much damage to the liver damage as is produced by chronic hepatitis C. There is a high incidence of HCV infection among hemodialysis patients, there is significant concern about viral transmission. HCV infection is a major problem in hemodialysis (HD) units even though blood products are screened for anti-HCV antibodies and other precautions are taken. The aim of this study was to determine the prevalence of occult HCV infection in PBMC in chronic hemodialysis (CHD) patients in the dialysis unit at Theodor Bilharz Research Institute (TBRI) with HCV antibodies and HCV RNA negativity irrespective of their liver function tests. Methods Fifty-three patients who were repeatedly were anti-HCV negative and serum HCV-RNA negative and on regular hemodialysis for > six months were enrolled in the study, which was conducted in the dialysis unit of Nephrology Department at TBRI; there were 10 healthy matched controls. The patients were classified into two groups according to the result HCV RNA in their PBMCs. Serological markers of HCV infection, including anti-HCV antibody and serum HCV-RNA, were repeatedly negative for all patients included in the study. We collected serum and PBMC samples from the patients on the day they entered the study. The test of all serum samples for anti-HCV antibodies and HCV-RNA was repeated by RT-PCR to ensure that the patients did not have these HCV serologic markers, We also measured their ALT and GGT levels. Results Occult hepatitis C virus infection (OCI) was detected in 15.1% of our CHD patients without any evidence of chronic liver disease. Conclusion Occult HCV infection was present among the hemodialysis patients irrespective of whether they had persistent

    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.

    Background Depression and anxiety are common among hemodialysis patients and affect their treatment outcomes. Dialysis adequacy also affects the hemodialysis patients’ survival rates. Objectives This study aimed to evaluate the correlation between anxiety and depression with dialysis adequacy. Patients and Methods In this cross-sectional study, 127 hemodialysis patients (73 males, 57.5%) with the mean age of 55.7 ± 17.5 were enrolled. Demographic and recent laboratory data were collected using self-administered questionnaires and by reviewing medical records. Dialysis adequacy measures including the Kt/V and urea reduction rate (URR) were calculated using standard formulas. The Hospital Anxiety and Depression Scale (HADS) was used to diagnose depression and anxiety. Independent sample t-test and Chi-square test were used to compare the values in different groups. Pearson correlations and linear regression were used to analyze the data using SPSS version 21. Results The prevalence rates of depression and anxiety (HADS score ≥ 8) were 31.5% and 41.7%, respectively. The prevalence of both conditions was significantly higher in women than in men (P < 0.05). The mean values of Kt/V and URR were not different in patients with and without depression or anxiety. The anxiety scores were correlated with age (P = 0.007, r = -0.24) and parathyroid hormone (P = 0.04, r = -0.19). Younger age and lower parathyroid hormone were the only factors that predicted higher scores of anxiety in linear regression. The Kt/V or URR were not significantly correlated with depression and anxiety scores. Conclusions Depression and anxiety are common among hemodialysis patients. There are no statistically significant correlation between depression and anxiety and dialysis adequacy. PMID:27803725

    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

    Both cognitive impairment and malnutrition are common in hemodialysis patients and associated with adverse clinical outcome. The aim of the study was to investigate performance on a detailed cognitive and psychomotor battery in maintenance hemodialysis patients in correlation to nutritional status. A selected population of 65 adult (20 females and 45 males, aged 57.84±12.28 years) hemodialysis (4.78±3.62 years) patients were investigated. The total time of test solving was correlated with Dialysis Malnutrition Score (DMS) in tests of simple visual discrimination of signal location (r=0.215, P=0.042), simple convergent visual orientation (r=0.262, P=0.020), and convergent thinking (r=0.244, P=0.034). The minimum time of test solving was also correlated with DMS in the test of simple convergent visual orientation (r=0.227, P=0.038), and in the test of convergent thinking (r=0.223, P=0.048). Total ballast, as a descriptor of stability in reaction time, was correlated with DMS in the test of simple visual discrimination of signal location (r=0.281, P=0.012), and in a test of short term memory actualization (r=0.239, P=0.028). Furthermore, significant correlation was noted between body mass index, serum creatinine, total cholesterol and albumin level with cognitive-psychomotor performance. Hemodialysis patients with a poorer nutritional status performed worse on cognitive and psychomotor tests. Further research is needed to assess the effects of treating malnutrition on cognitive-psychomotor performance in these patients.

    Background: 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). Methods: 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. Results: 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). Conclusion: 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

    Background: Psychomotor retardation (PR) is one of the core features in depression according to DSM V (1), but also aging in itself causes cognitive and psychomotor slowing. This is the first study investigating PR in relation to cognitive functioning and to the concomitant effect of depression and aging in a geriatric population ruling out contending effects of psychotropic medication. Methods: A group of 28 non-demented depressed elderly is compared to a matched control group of 20 healthy elderly. All participants underwent a test battery containing clinical depression measures, cognitive measures of processing speed, executive function and memory, clinical ratings of PR, and objective computerized fine motor skill-tests. Statistical analysis consisted of a General Linear Method multivariate analysis of variance to compare the clinical, cognitive, and psychomotor outcomes of the two groups. Results: Patients performed worse on all clinical, cognitive, and PR measures. Both groups showed an effect of cognitive load on fine motor function but the influence was significantly larger for patients than for healthy elderly except for the initiation time. Limitations: Due to the restrictive inclusion criteria, only a relatively limited sample size could be obtained. Conclusion: With a medication free sample, an additive effect of depression and aging on cognition and PR in geriatric patients was found. As this effect was independent of demand of effort (by varying the cognitive load), it was apparently not a motivational slowing effect of depression. PMID:25674065

    Effects of online hemodiafiltration (HDF) using acetate-free bicarbonate dialysis (AFD) fluid on microinflammation, resulting in improved nutritional status in hemodialysis patients, were examined and compared with conventional acetate-containing bicarbonate dialysis (ACD) fluid. A total of 24 hemodialysis patients were registered for a cross-over design study for a 6-month period. These patients were subjected to ACD for the first 3 months followed by AFD fluid for the latter 3 months. Blood variables of C-reactive protein (CRP), interleukin-6 (IL-6), leptin, neuropeptide Y (NPY), protein catabolic rate (PCR) and %creatinine (Cr) index were determined after the first and last 3-month period. The filters and the conditions of HDF and drug regimens including erythropoiesis-stimulating agents were unchanged throughout the cross-over study. Predialysis blood pH and bicarbonate were significantly higher in the AFD phase than in the ACD phase. Blood CRP and IL-6 levels were significantly decreased in the AFD group compared to the ACD group. Concerning nutritional evaluation, leptin and NPY were significantly lower and higher, respectively, in the AFD phase than in the ACD phase. PCR tended to be higher in the AFD phase than in the ACD phase. A significantly higher %Cr index level was observed in the AFD phase than in the ACD phase. These results suggest that online HDF using AFD fluid contributes to alleviating bioincompatible events associated with microinflammation, leading to improvement in the nutritional status in hemodialysis patients.

    Heparin is routinely administered at high doses during hemodialysis to patients with hypercoagulable states. This study aimed to evaluate the safety and efficacy of low-dose heparin in combination with urokinase in this patient population. The presence of a hypercoagulable state was confirmed by thromboelastography. Doses of heparin and urokinase were adjusted based on activated partial thromboplastin time (APTT). Clotting in the extracorporeal circuit was evaluated by a semi-quantitative index. Prothrombin time (PT) and APTT were measured before, during and after dialysis. Kt/V(urea) was used to assess the efficacy of dialysis. D-dimer levels were measured 2 h after the start of hemodialysis. Hemodialysis data with heparin administered alone prior to dialysis were used as control in the present study. With urokinase treatment, the initial dose of heparin was reduced by 45.0 ± 11.4% during hemodialysis and the maintenance dose by 46.8 ± 12.8% compared with heparin alone. No side effects due to urokinase were observed. Bleeding events were rare. Post-dialysis PT (12.99 ± 1.41 vs. 15.22 ± 3.12 s, p = 0.02) and APTT (97.75 ± 43.62 vs. 140.16 ± 30.12 s, p = 0.002) with urokinase plus heparin were significantly shorter than with heparin alone. Finally, during dialysis, D-dimer levels were significantly higher with heparin alone (0.21 ± 0.11 mg/L) than with heparin and urokinase (0.169 ± 0.122 mg/L, p = 0.017). In conclusion, urokinase significantly reduced the dose of heparin required during hemodialysis without any side effects in patients with hypercoagulable states during hemodialysis.

  19. Management of Elderly Patients With Gliomas

    The current progressive aging of the population is resulting in a continuous increase in the incidence of gliomas in elderly people, especially the most frequent subtype, glioblastoma (GBM). This sociohealth shift, known as the “silver tsunami,” has prompted the neuro-oncology community to investigate the role of specific antitumor treatments, such as surgery, radiotherapy, chemotherapy, and other targeted therapies, for these traditionally undertreated patients. Advanced age, a widely recognized poor prognostic factor in both low-grade glioma (LGG) and high-grade glioma patients, should no longer be the sole reason for excluding such older patients from receiving etiologic treatments. Far from it, results from recent prospective trials conducted on elderly patients with GBM demonstrate that active management of these patients can have a positive impact on survival without impairing either cognition or quality of life. Although prospective studies specifically addressing the management of grade 2 and 3 gliomas are lacking and thus needed, the aforementioned tendency toward acknowledging a therapeutic benefit for GBM patients might also apply to the treatment of patients with LGG and anaplastic gliomas. In order to optimize such etiologic treatment in conjunction with symptomatic management, neuro-oncology multidisciplinary boards must individually consider important features such as resectability of the tumor, functional and cognitive status, associated comorbidities, and social support.

    Background Rapid growth of the elderly peritoneal dialysis (PD) population is posing a special challenge for renal teams. Peripheral artery disease (PAD) has been reported to be an independent predictor of cardiovascular and all-cause mortality in hemodialysis patients. However, the prevalence and associated risk factors for PAD in elderly PD patients have not yet been fully investigated. Methods A total of 69 elderly PD patients were included in the present study. PAD was defined as either an ankle-brachial index < 0.9 or a history of intermittent claudication, lower-limb amputation, foot ulcers, or gangrene. On enrollment, clinical and biochemical characteristics were collected. Results The overall prevalence of PAD was 31.9%. Compared with non-PAD patients, PAD patients were significantly older and more likely to be female and have longer PD duration and lower diastolic blood pressure (P < 0.001, = 0.002, 0.018, and 0.007, respectively). Serum albumin level (P < 0.001) and residual renal Kt/V value (P < 0.001) were significantly lower, but the serum C-reactive protein level (P = 0.005) was significantly higher, in PAD patients compared with non-PAD patients. Logistic regression analysis showed that serum albumin level (odds ratio = 1.485, P = 0.040) and residual renal Kt/V value (odds ratio = 1.725, P = 0.016) were independently associated with PAD. Conclusion A high prevalence of PAD appeared among elderly PD patients in Macao. Serum albumin level and residual renal Kt/V value were independently related to PAD. PMID:23112578

    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.

    Spiritual strategies may provide an effective way of coping with disease. This study sought to investigate the validity and reliability of the Persian version of the spiritual coping strategies (SCS) scale among Iranian hemodialysis patients. A convenience sample of 204 hemodialysis patients was recruited to participate in the study. A forward-backward translation method was used to produce the Persian version of the scale. Internal consistency was assessed by Cronbach's alpha and item-total score correlation. Two-week test-retest reliability was also assessed. The convergent and divergent validity of the scale was evaluated using the Duke University Religion Index and a visual analogue scale for health status. Exploratory and confirmatory factor analyses were used to assess the factor structure. Participants consisted of 113 males and 91 females (mean age 57.2 [SD = 9.7]). Cronbach's alpha was acceptable (0.87). We found two underlying factors similar to the original scale. The correlations between the study scales confirmed the convergent and divergent validity of the SCS. Confirmatory factor analysis showed a good fit to the data (GFI = 0.923, CFI = 0.948 and RMSEA = 0.068). The Persian version of the SCS has sound psychometric properties in Iranian hemodialysis patients. Future research should consider applying the scale to populations with other religious/cultural backgrounds. PMID:23504574

    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.

    In elderly patients, a blunt trauma of the chest is associated with a significant risk of complications and mortality. The number of ribs fractures (≥ 4), the presence of bilateral rib fractures, of a pulmonary contusion, of existent comorbidities or acute extra-thoracic traumatic lesions, and lastly the severity of thoracic pain, are indeed important risk factors of complications and mortality. Their presence may require hospitalization of the patient. When complications do occur, they are represented by alveolar hypoventilation, pulmonary atelectasia and broncho-pulmonary infections. When hospitalization is required, it may allow for the specific treatment of thoracic pain, including locoregional anesthesia techniques. PMID:26449103

    The examination of an elderly patient often requires special techniques and attention to the patient's comfort and ease. This paper outlines a reasonable approach to each phase of the interview and discusses the particular medical problems of this age group. Older people are often slow to bring their troubles to medical attention because their symptoms are vague or because they accept their disability as part of old age. Sometimes they have difficulty in communicating effectively with the physician. Simple patience can ease an otherwise frustrating situation. PMID:7104901

    The prevalence of heart failure (HF) increases with age. While clinical trials suggest that contemporary evidence-based HF therapies have reduced morbidity and mortality, these trials largely excluded the elderly. Questions remain regarding the clinical characteristics of elderly HF patients and the impact of contemporary therapies on their outcomes. This review presents the epidemiology of HF in the elderly and summarizes the data on the pathophysiology of the ageing heart. The clinical characteristics, treatment patterns, and outcomes of elderly HF patients are explored. Finally, the main gaps regarding HF therapies in the elderly and the opportunities for future trials are highlighted. PMID:23429975

    The prevalence of hepatitis C virus (HCV) infection was evaluated in 227 hemodialysis patients from four units in Caracas, Venezuela, by using different second- and third-generation enzyme immunoassays (EIAs) and immunoblot assays. HCV antibodies were detected in 162 patients (71%) by the recombinant-based second-generation assays (Abbott and Ortho) and in 161 patients by the synthetic peptide-based EIA (UBI). Of the 162 HCV antibody-positive serum samples, 161 were confirmed to be positive by RIBA 3. HCV RNA was detected in 49 of 68 (72%) of the seropositive patients and in 5 of 21 (24%) of the seronegative ones. HCV RNA was not always correlated with an increase in alanine aminotransferase (ALT) levels. Among 20 patients positive for HCV RNA and for HCV antibodies (without any hepatitis B virus [HBV] marker), only 10 had elevated ALT levels. The possible interference of HBV for HCV replication was evaluated. No significant difference was found between the presence of HCV RNA and the presence of any HBV serological markers. The possible routes of transmission of HCV in hemodialysis patients are multiple, and some of them are still controversial. Of the HCV-positive patients, 30% received a blood transfusion, significantly more than the 15% found for the HCV-negative group. However, blood transfusions alone could not account for the high incidence observed in this group of patients (38% from 1994 to 1995). In conclusion, about one-quarter of the apparently non-HCV-infected patients were probably seroconverting, ALT may not be a useful indicator of HCV infection in hemodialysis patients, and nosocomial transmission of HCV may play a role in the spread of HCV in this group.

  9. A pharmacy-based medication reconciliation and review program in hemodialysis patients: a prospective study

    PubMed Central

    Foote, Edward F.

    2016-01-01

    Background: Hemodialysis (HD) patients are on multiple medications, see many prescribers and have many hospitalizations which put them at risk for medication record discrepancies and medication related problems (MRP). Being able to effectively identify and reconcile these medication issues is crucial in reducing hospitalizations, morbidities, and mortalities. The care of the hemodialysis patients can be enhanced by incorporating a pharmacist into the interprofessional team. There is little data in the literature on medication record discrepancies and MRP’s in dialysis patients. Objective: The objectives of this research were to determine the types of medication discrepancies and MRPs in dialysis patients and if recommendations for changes based on these findings were accepted by providers. Methods: Patients were asked to bring medications to the dialysis unit for review. Discrepancy and MRP recommendations were communicated to the unit staff via written progress notes. A follow-up was performed an average of 33 days later to determine if the recommendations were accepted. Results: Overall, in 93 unique patients, 376 discrepancies (3.1 per patient) and 64 MRPs (0.5 per patient) were identified. The most common type of discrepancy and MRP was drug omission and indication without drug, respectively. Of the total 440 interventions, 77% were ultimately accepted. Discrepancies were more likely to be accepted as compared to MRPs (85% vs. 27%, respectively). Conclusion: Medication record discrepancies and MRPs are common in dialysis patients. Recommendations related to discrepancies were more likely to be accepted by the providers as compared to MRPs. Medication records became inaccurate within 12 months. A pharmacy-based medication reconciliation and review program may have an important impact on the care of hemodialysis patients.

    Chronic inflammation is highly prevalent in maintenance hemodialysis (MHD) patients, and it has been shown to be a strong predictor of morbidity and mortality. Mitochondrial DNA (mtDNA) released into circulation after cell damage can promote inflammation in patients and animal models. However, the role and mechanisms of circulatory mtDNA in chronic inflammation in MHD patients remain unknown. Sixty MHD patients and 20 health controls were enrolled in this study. The circulatory mtDNA was detected by quantitative real-time PCR assay. Plasma interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) were quantitated by ELISA assay. Dialysis systems in MHD patients and in vitro were used to evaluate the effect of different dialysis patterns on circulatory mtDNA. Circulatory mtDNA was elevated in MHD patients comparing to that of health control. Regression analysis demonstrated that plasma mtDNA was positively associated with TNF-α and the product of serum calcium and phosphorus, while negatively associated with hemoglobin and serum albumin in MHD patients. MtDNA induced the secretion of IL-6 and TNF-α in the THP-1 cells. Single high-flux hemodialysis (HF-HD) and on line hemodiafiltration (OL-HDF) but not low-flux hemodialysis (LF-HD) could partially reduce plasma mtDNA in MHD patients. In vitro, both HD and hemofiltration (HF) could fractional remove mtDNA. Collectively, circulatory mtDNA is elevated and its level is closely correlated with chronic inflammation in MHD patients. HF-HD and HDF can partially reduce circulatory mtDNA in MHD patients. PMID:25485699

    The aim of this study was to evaluate the relationship between arterial microcalcification (AMiC) and erythropoiesis-stimulating agents (ESA) hyporesponsiveness in hemodialysis patients. The presence of AMiC was confirmed by pathologic examination of von Kossa-stained arterial specimens acquired during vascular access surgery. We assessed the ESA hyporesponsiveness index (EHRI), defined as the weekly ESA dose per kilogram body weight divided by the hemoglobin level. AMiC was detected in 33 (40.2%) of 82 patients. Patients with diabetes had a higher incidence of AMiC than patients without diabetes. The serum levels of albumin and cholesterol were higher in patients without AMiC than in patients with AMiC. The serum levels of intact parathyroid hormone were lower in patients with AMiC than in patients without AMiC. The serum levels of phosphate and calcium-phosphorus product did not differ between the two groups. The mean EHRI value was higher in patients with AMiC than in patients without AMiC. In multivariate analyses, ESA hyporesponsiveness and diabetes showed a significant association with AMiC. In conclusion, ESA hyporesponsiveness may be a clinical relevant parameters related to AMiC in hemodialysis patients.

    Introduction Intima-media thickness (IMT) of the carotid artery is a widely accepted parameter for detection and quantification of atherosclerosis. The aim of the study was the evaluation of the impact of changes of IMT on the mortality of patients on hemodialysis. Methods The study was organized as a prospective and observational one. Intima-media thickness was determined by ultrasound in 194 patients who were evaluated every year during a three-year period. We analyzed the mortality rate of patients on hemodialysis in relation to their biochemical parameters, demographic and anthropometric characteristics, type of dialysis, smoking habits and statin therapy. Results Female gender and hemodiafiltration emerged as good predictors of long-term survival. Baseline IMT values were significantly lower than those at the end of the second (p <0.001) and third years of the study (p <0.001). The baseline values positively correlated with uric acid levels (p =0.027) and body mass index (p =0.024), while at the end of the second year, IMT positively correlated with LDL-cholesterol (p =0.037) and triglyceride levels (p =0.018) and body mass index (p =0.045). Patients on hemodiafiltration had significantly higher values for erythrocytes (p =0.047), hemoglobin (p =0.005), creatinine (p =0.048), Kt/V (p =0.026), albumin (p =0.012), LDL-cholesterol (p <0.001), body mass index (p <0.001),and lower IMT values at the end of the first year (p =0.039), compared to patients on bicarbonate hemodialysis. Predictors of death were the duration of hemodialysis (p <0.001), and IMT at the end of the first (p =0.008) and second years of the study (p =0.005). Conclusion Dynamic changes of IMT of the carotid arteries during the first two years were found in our study to be predictors of mortality in patients on hemodialysis.

    Background Studies have shown that family caregivers of hemodialysis patients experience high levels of burden. However, these caregivers are often neglected, and no studies are available on the effectiveness of coping strategies on the burden of care among these caregivers. Objectives This study aimed to examine the effectiveness of problem-focused coping strategies (communication skills, anger management, and deep breathing) on the burden on caregivers of hemodialysis patients. Patients 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. The subjects were equally allocated into two groups of 38. Through a coin-tossing method, caregivers of patients who referred on even or odd days of the week were randomly assigned into the intervention group or the control group, respectively. The intervention group received four training sessions on problem-focused coping strategies, but the control group did not receive any intervention. Both groups answered the caregiver’s burnout inventory at the start and six weeks after the last educational session. Descriptive statistics, chi-square, Fisher’s exact test, independent-samples t-test, and Mann-Whitney U test were used to analyze the data. Results The majority of caregivers (54%) were in the age range of 35 - 55 years, female (68.4%), and married (70%). No significant difference was found between the baseline mean caregivers’ burden scores of the intervention and control groups (88.56 ± 11.74 vs. 84.97 ± 15.13, P = 0.308). However, the mean caregivers’ burden in the intervention group decreased, and the two groups were significantly different at the end of the study (58.77 ± 6.64 vs. 87.84 ± 11.74, P < 0.001). Conclusions The current study showed the effectiveness of problem-focused coping strategies on reducing the burden on caregivers of hemodialysis patients. Authorities and

    Purpose: To report our experience and results with the endovascular treatment of central vein stenoses and occlusions in hemodialysis patients. Methods: Between October 1999 and August 2001 (22 months) we performed 22 interventional procedures in 14 hemodialysis patients (8 women, 6 men) ranging in age from 38 to 87 years (mean 76 years). The indication for intervention was stenosis (n = 10) or occlusion (n =4) of a central vein in the upper arm used for dialysis inpatients with arm swelling and/or shunt malfunction. All patients had a previous history of subclavian vein cannulation. There were six percutaneous transluminal angioplasties (PTAs) and eight primary stentplacements and eight repeat interventions. Seven were for restenoses and one for early occlusion, with two secondary stent placements and six PTA of in-stent stenoses. In two patients a second stent was implanted. The mean follow-up was 8.5 months (range 1-19 months). All stents were self-expandable with diameters ranging from 9 to 16 mm. Results: All but one of the procedures was technically successful (95%, n = 21). The patient with an unsuccessful procedure died 1 month after the procedure, but the death was not procedure-related. During follow-up three patients died with a patent shunt and central vein, none of them in connection with the procedure. No complication occurred during the interventional procedures. One patient was lost to follow-up. The primary patency rate at 12 months was 43%, with a primary assisted patency rate of 83% and a secondary patency rate of 100% (n 6). Conclusion: Central vein stenoses and occlusions are associated with previous subclavian vein cannulation. They are a serious problem in hemodialysis patients with a shunt on the same arm.Endovascular treatment is a suitable option for these patients.

    Double lumen hemocatheter is commonly used for temporary hemodialysis patient and various complications have been documented but few reports of guide wire-related complications. We report a complication of double lumen hemocatheter guide wire entrapment in a 43-year-old female of type 1 diabetes mellitus and hemodialysis patient. She was admitted for left arteriovenous shunt dysfunction and right internal jugular vein hemocatheter chamber clotting was found while on hemodialysis, so a new hemocatheter was changed over guide wire. Guide wire was introduced without any resistance and the clotting hemocatheter was removed. During the procedure, the J-tipped guide wire could not be withdrawn and portable chest radiography revealed the J-tip of the guide wire was in the right ventricle near the region of tricuspid valve. Fluoroscopy was arranged and it also confirmed the J-tip was lying in the ventricle near the tricuspid valve where it was stuck. Snare catheter kit was inserted through the 10 Fr sheath and the cardiologist untied the knot by endovascular snare and removed the guide wire smoothly. This report emphasizes the importance of awareness on guide wire entrapment while inserting double lumen hemocatheter. When a guide wire became hard to withdraw, extracting an entrapped guide wire with fluoroscopy guide and snare catheter is a preferable and minimal invasive approach.

    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 = 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 hypertension

    The population of Hong Kong and the proportion of elderly people have been increasing rapidly. The aim of this retrospective cohort study is to determine predictive factors for psychiatric rehospitalization within 2 years among elderly patients who were discharged from psychiatric wards, in attempt to reduce their rehospitalization rate and to reintegrate them into the community. Patients aged 65 and over, who were discharged from psychiatric wards of Pamela Youde Nethersole Eastern Hospital from 1 March 2010 to 29 February 2012, were identified. Rehospitalization within 2 years after discharge was the primary outcome measure, and the time to rehospitalization was measured as the secondary outcome. Patients were subgrouped into readmitted and non-readmitted groups. Logistic regression and Cox regression analyses were applied to the potential predictive factors with odds ratios and hazard ratios obtained, respectively, for the significant findings. Kaplan-Meier survival curves were plotted for graphical representation of the study results in survival analysis. 368 individuals satisfying the study criteria were identified. The same four factors were shown to be significantly associated with rehospitalization in both multiple logistic regression and Cox regression survival analysis. Referral to other psychiatric disciplines upon discharge (p< 0.001, OR=0.325, HR=0.405) was associated with a lower rehospitalization risk and correlated to a longer time to rehospitalization. History of suicidal behaviors (p< 0.001, OR=4.906, HR=3.161), history of violent behaviors (p< 0.001, OR=5.443, HR=3.935) and greater number of previous psychiatric admissions (p< 0.001, OR=1.250, HR=1.121)  were associated with a higher rehospitalization risk and predicted earlier rehospitalization. The rehospitalization rate of elderly patients was 5.2% at 1 month, 9.5% at 3 months, 15.0% at 6 months, 17.1% at 1 year, 18.8% at 1.5 year and 20.9% at 2 years. PMID:26870319

    Lanthanum carbonate (LaC) is a non-calcium-based phosphate binder used to treat hyperphosphatemia in patients with chronic kidney disease. Oral administration of LaC is difficult in patients undergoing tube feeding or those who are of advanced age because it is essential to chew the LaC tablet sufficiently before swallowing it. We report two cases in whom crushed LaC was used in hemodialysis patients undergoing tube feeding. In both cases, previously crushed LaC was mixed into enteral nutrients. We found that LaC administered this way was effective for decreasing serum phosphorus levels.

    A strong emphasis on self-management for health maintenance in a variety of chronic diseases has been shown to benefit patients' outcomes and quality of life. However, little has been published on such programs in patients with chronic kidney disease. We studied the feasibility and effectiveness of the Chronic Disease Self-Management Program (CDSMP) in 14 patients with ESRD undergoing conventional hemodialysis. This program is designed to enhance skills in the areas of medical, emotional, and role management. Outcome measures in health status, self-management behaviors, self-efficacy, and health care utilization were evaluated through use of questionnaires at baseline and after six months. PMID:26263750

    Hepatocellular carcinoma (HCC) is the second most common cause of death by cancer in the world. Due to the delayed HCC development in hepatitis C carriers and nonalcoholic fatty liver disease, the incidence of HCC in the elderly is increasing and is becoming a global health issue. Elderly patients with HCC should be assessed through proper oncologic approach, namely, screening tools for frailty (Geriatric-8 or Vulnerable Elders Survey-13) and comprehensive geriatric assessment. This review of the literature supports the same treatment options for elderly patients as for younger patients, in elderly patients selected as fit following proper oncogeriatric assessment. Unfit patients should be managed through a multidisciplinary team involving both oncological and geriatrician professionals. Specific studies and recommendations for HCC in the elderly should be encouraged. PMID:27574587

    Summary Background and Objectives A high body mass index (BMI) is associated with lower mortality in patients undergoing hemodialysis. Short-term weight gains and losses are also related to lower and higher mortality risk, respectively. The implications of weight gain or loss may, however, differ between obese individuals and their nonobese counterparts. Design, Setting, Participants, & Measurements The Current Management of Secondary Hyperparathyroidism: A Multicenter Observational Study (COSMOS) is an observational study including 6797 European hemodialysis patients recruited between February 2005 and July 2007, with prospective data collection every 6 months for 3 years. Time-dependent Cox proportional hazard regressions assessed the effect of BMI and weight changes on mortality. Analyses were performed after patient stratification according to their starting BMI. Results Among 6296 patients with complete data, 1643 died. At study entry, 42% of patients had a normal weight (BMI, 20–25 kg/m2), 11% were underweight, 31% were overweight, and 16% were obese (BMI ≥30 kg/m2). Weight loss or gain (<1% or >1% of body weight) was strongly associated with higher rates of mortality or survival, respectively. After stratification by BMI categories, this was true in nonobese categories and especially in underweight patients. In obese patients, however, the association between weight loss and mortality was attenuated (hazard ratio, 1.28 [95% confidence interval (CI), 0.74 to 2.14]), and no survival benefit of gaining weight was seen (hazard ratio, 0.98 [95% CI, 0.59 to 1.62]). Conclusions Assuming that these weight changes were unintentional, our study brings attention to rapid weight variations as a clinical sign of health monitoring in hemodialysis patients. In addition, a patient’s BMI modifies the strength of the association between weight changes with mortality. PMID:24009217

    Abstract Skin changes are common in patients on dialysis. This study focused on putative associations of specific skin findings with comorbidities and mortality. We performed a retrospective analysis of data from 508 patients on maintenance hemodialysis therapy in 7 centers in the German State of North Rhine Westphalia. Data had been collected by interview, from patient files, and from targeted physical examination in an earlier prospective study screening hemodialysis patients for the presence of nephrogenic systemic fibrosis. While on dialysis, patients’ extremities had been examined for any of the following: edematous skin at the lower extremities, hyperpigmentation, induration, and xerosis cutis. Our present data analyses focused on associated mortality and comorbidities. Five hundred eight patients (median age 71 years, range 20.0–95.9; n = 292 men) had agreed to participate in the initial study: 48% (n = 243) were diabetics and 46% (n = 232) had been diagnosed with coronary heart disease. On examination, 86% of patients (n = 439) presented with at least 1 of the prespecified skin changes. Skin edema (n = 89; 18%), hyperpigmentation (n = 74; 15%), and induration (n = 9; 2%) were independently associated with increased mortality over 24 months (P < 0.002, P < 0.030, and P < 0.020, respectively). In our study, prespecified skin changes indicated an increased mortality risk in patients on chronic hemodialysis. Routinely assessing the skin of dialysis patients represents a simple, reliable, and cost effective means of identifying those at greatest risk. PMID:27015187

    Left ventricular hypertrophy and myocardial fibrosis frequently occur in patients with end-stage renal disease receiving hemodialysis therapy and are associated with poor prognosis. Native T1 mapping is a novel cardiac magnetic resonance imaging technique that measures native myocardial T1 relaxation, a surrogate of myocardial fibrosis. Here we compared global and segmental native myocardial T1 time and global longitudinal, circumferential and segmental strain, and cardiac function of 35 hemodialysis patients and 22 control individuals. The median native global T1 time was significantly higher in the hemodialysis than the control group (1270 vs. 1085 ms), with the septal regions of hemodialysis patients having significantly higher median T1 times than nonseptal regions (1293 vs. 1252 ms). The mean peak global circumferential strain and global longitudinal strain were both significantly reduced in hemodialysis patients compared with controls (-18.3 vs. -21.7 and -16.1 vs. -20.4, respectively). Systolic strain was also significantly reduced in the septum compared with the nonseptal myocardium in hemodialysis patients (-16.2 vs. -21.9) but not in control subjects. Global circumferential strain and longitudinal strain significantly correlated with global native T1 values (r = 0.41 and 0.55, respectively), and the septal native T1 significantly correlated with the septal systolic strain (r = 0.46). Thus, myocardial fibrosis may be assessed noninvasively with native T1 mapping; the interventricular septum appears to be particularly prone to the development of fibrosis in hemodialysis patients.

    Randomized control trials (RCTs) are considered as most rigors way of determining the cause-effect relationship of a treatment and outcome. Activation of rennin angiotensin aldosterone system (RAAS) is an important contributor to hypertension in hemodialysis patients. The prevalence of hypertension in hemodialysis patients varies from 60% to 80% and hypertension management alone with conventional hemodialysis is insufficient. Hence, the current review was aimed to investigate the effect of RAAS inhibitors in managing hypertension among hemodialysis patients in a randomized control trial. Using PUBMED and EMBASE databases, randomized control trial with primary or secondary outcomes related to the effect of RAAS inhibitors on blood pressure among hemodialysis patients were included for analysis. The current review also assessed the quality of reporting of RCT. A total of eight RCT met inclusion criteria for current review. According to modified jaded scale, one (12.5%) study scored four points for quality reporting, whereas two (25%) studies scored one point that was the least score. The mean score for all included studies was 2.25. Six (75%) of the eight RCT included, involved ARB in hypertension management among hemodialysis patients, whereas two (25%) studies involved angiotensin-converting enzyme (ACE) inhibitors. Of the siz RCT involving ARB, two (33.3%) RCT also included ACE inhibitors comparison group. Altogether six (75%) studies report a reduction in blood pressure with the use of RAAS inhibitors compared to control group; however, of the six studies, two (33.3%) reported that the reduction in blood pressure was not significant. Whereas, two (25%) studies reported no reduction in blood pressure compared to the control group. The findings from current review do not indicate a clear pattern for a role of RAAS inhibitors for hypertension control among hemodialysis patients. PMID:26853680

    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.

    Background In addition to physical adaptation and psychosocial adjustment to chronic renal disease, hemodialysis (HD) patients must also adapt to dialysis therapy plan. Objectives The aim of the present study was to examine the effect of Roy’s adaptation model-based patient education on adaptation of HD patients. Patients and Methods This study is a semi-experimental research that was conducted with the participation of all patients with end-stage renal disease referred to the dialysis unit of Shahid Beheshti Hospital of Yasuj city, 2010. A total of 59 HD patients were randomly allocated to two groups of test and control. Data were collected by a questionnaire based on the Roy’s Adaptation Model (RAM). Validity and reliability of the questionnaire were approved. Patient education was determined by eight one-hour sessions over eight weeks. At the end of the education plan, the patients were given an educational booklet containing the main points of self-care for HD patients. The effectiveness of education plan was assessed two months after plan completion and data were compared with the pre-education scores. All analyses were conducted using the SPSS software (version 16) through descriptive and inferential statistics including correlation, t-test, ANOVA and ANCOVA tests. Results The results showed significant differences in the mean scores of physiological and self-concept models between the test and control groups (P = 0.01 and P = 0.03 respectively). Also a statistical difference (P = 0.04) was observed in the mean scores of the role function mode of both groups. There was no significant difference in the mean scores of interdependence modes between the two groups. Conclusions RAM based patient education could improve the patients’ adaptation in physiologic and self-concept modes. In addition to suggesting further research in this area, nurses are recommended to pay more attention in applying RAM in dialysis centers. PMID:24396575

    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%.

    Background and objectives: Hemodialysis patients with type 2 diabetes exhibit an excessive cardiovascular risk and regularly receive heparin. We tested whether antibodies to the platelet factor 4–heparin complex (PF4-H-AB) contribute to outcome. Design, setting, participants, & measurements: In 1255 hemodialysis patients with type 2 diabetes, the German Diabetes Dialysis Study evaluated the effect of atorvastatin (20 mg/d) versus placebo. In a post hoc analysis, the association among PF4-H-ABs, biochemistry, and prespecified, centrally adjudicated end points (combined cardiovascular end point [CVE], all-cause mortality, sudden death, myocardial infarction, stroke) was investigated. Results: During 4 years, 460 patients reached the CVE; 605 died, 159 of sudden death. Myocardial infarction and stroke occurred in 199 and 97 patients, respectively. Positive PF4-H-AB status was found in 231 (18.7%) of 1236 tested patients and was associated with lower albumin, higher C-reactive protein, and arrhythmia. In a multivariate model adjusted for demographics, comorbidities, and biochemistry, PF4-H-ABs were associated with sudden death. No significant association between PF4-H-ABs and all-cause mortality, myocardial infarction, stroke, or the CVE was observed. Detecting an interaction between acetylsalicylic acid and PF4-H-ABs regarding sudden death and mortality, we found that the association between PF4-H-ABs and outcomes was restricted to patients with acetylsalicylic acid use, most likely because of indication bias. Conclusions: In hemodialysis patients who have type 2 diabetes and are treated with acetylsalicylic acid, PF4-H-ABs are associated with sudden and all-cause death. Further studies are needed to elucidate this association. PMID:20185595

    In hemodialysis patients, C-reactive protein (CRP), an acute-phase reactant, is a sensitive and independent marker of malnutrition, anemia, and cardiovascular mortality. The aim of the present study was to evaluate CRP levels in plasma samples from long-term hemodialysis patients on different extracorporeal modalities and dialyzed with different membranes, at baseline and after 6 months. Two hundred and forty-seven patients were recruited in eight hospital-based centers. All patients had been on their dialytic modality for at least 3 months and were prospectively followed in their initial dialytic modality for 6 months. Patients were treated with conventional bicarbonate dialysis (N = 127) or hemodiafiltration (N = 120). Patients treated with conventional bicarbonate dialysis were dialyzed with different membranes: Cuprophane (N = 51), low-flux cellulose modified membrane (N = 37) and synthetic membranes (N = 39). Hemodiafiltration was performed in post-dilution mode with polysulfone (N = 66) and polyacrylonitrile (N = 54) membranes. Analysis of baseline CRP values in the clinically stable patients showed that an unexpectedly high proportion (47%) of the patients had CRP values higher than 5 mg/l (upper limit in normal subjects). The mean +/- S.D. CRP values were significantly higher (P < 0.05) in hemodiafiltration with infusion volumes < 10 l per session (14.6+/-3.1 mg/l) than in standard hemodialysis (5.1 +/- 2.1 mg/l) and hemodiafiltration with infusion volumes > 20 l per session (4.9 +/- 2.1 mg/l). These values did not significantly change after 6 months of follow-up. Concerning the membranes, the highest levels of CRP were observed in patients dialyzed with Cuprophane with a significant increase from 15.1 +/- 3.6 to 21.2 +/- 3.1 mg/l after 6 months (P < 0.05); a significant reduction of CRP levels was observed in patients dialyzed with polysulfone in the same follow-up period (from 13.5 +/- 2.9 to 8.1 +/- 2.4 mg/l; P < 0.05).

    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. PMID:25154423

    Quotidian/intensive hemodialysis (short daily and nocturnal) has variable effects on health-related quality of life (HRQOL) as measured by standard HRQOL tools. We sought to understand the perceived benefits and limitations of quotidian dialysis by interviewing patients who had switched from conventional to home quotidian dialysis. We used a qualitative, phenomenological approach to explore the perceived benefits of quotidian dialysis from 10 patients using either short daily or nocturnal hemodialysis at a tertiary health care center in London, Canada. The patients varied in gender, age, employment status, home support, physical capacity, primary cause of kidney disease, previous forms of renal replacement therapy, and level of education. Four major themes emerged: (1) improvement in physical and mental well-being including better blood pressure and concentration, (2) increased control over patient's own life including time availability, choosing when to dialyze, and dialyzing at home, (3) decreased perception of being sick including returning to regular employment and avoiding sicker patients who must have in-center dialysis, and (4) identification of the competencies and supports required for quotidian dialysis including ability to provide self-care, supportive family, and medical support. Our findings suggest when patients' willingness and physical ability to use quotidian dialysis are coupled with education and support systems to assist patients' and families' self-directed care, patients qualitatively perceive benefits of both increased physical and mental health, both measures of health-related quality of life.

    Since caregivers have roles and responsibilities in all phases from the diagnosis of the disease to discharge and homecare, their care burdens increase. The problems experienced by caregivers, whose care burden increase and accordingly whose life quality is deteriorated, complicate the treatment-receiving patient's adaptation to the disease. This study was performed to determine the burden to primary caregivers of patients undergoing dialysis. This descriptive study was conducted with the family caregivers of 114 patients from Erzurum Ataturk University's Medical Faculty Nephrology Department: 54 were relatives of patients receiving hemodialysis and 60 were relatives of patients receiving peritoneal dialysis during August to December 2014. The percentage of the patients with low levels of caregiver burden is 13% in the hemodialysis group, while it is 35% in the peritoneal dialysis group. These findings are statistically significant. To conclude, chronic diseases affect not only patients, but also their relatives who care for them. Nursing care needs to include both patients and their relatives and support them. It is hoped that this study will guide nursing care in this direction.

    Little attention has been given to the effects of registered nurse (RN) staffing and processes of nursing care on patient outcomes in hemodialysis units. This research examined the effects of patient-to-RN ratios and necessary tasks left undone by RNs on the likelihood of nurse-reported frequent occurrences of adverse patient events in chronic hemodialysis units. Study findings revealed that high patient-to-RN ratios and increased numbers of tasks left undone by RNs were associated with an increased likelihood of frequent occurrences of dialysis hypotension, skipped dialysis treatments, shortened dialysis treatments, and patient complaints in hemodialysis units. These findings indicate that federal, state, and dialysis organization policies must foster staffing structures and processes of care in dialysis units that effectively utilize the invaluable skills and services of professional, registered nurses.

    The Great East Japan Earthquake in 2011 caused an unprecedented imbalance between an increasing number of hemodialysis patients and medical staff shortage in the Sousou area, the site of the Fukushima nuclear power plants. In 2014, capacity of our hemodialysis center reached a critical limit due to such an imbalance. We attempted to evaluate the effort of medical staff to clarify to what extent their burden had increased post-disaster. The ratio of total dialysis sessions over total working days of medical staff was determined as an approximate indicator of effort per month. The mean value of each year was compared. Despite fluctuations of the ratio, the mean value did not differ from 2010 to 2013. However, the ratio steadily increased in 2014, and there was a significant increase in the mean value. This proposed indicator of the effort of medical staff appears to reflect what we experienced, although its validity must be carefully examined in future studies.

    The prevalence of hepatitis C virus (HCV) infection is high among patients receiving chronic hemodialysis. To clarify the risk ratio of HCV infection with respect to mortality and prognosis in chronic hemodialysis patients, a retrospective longitudinal cohort study was conducted in 2010 and involved 3,064 patients receiving chronic hemodialysis at nine dialysis facilities in Hiroshima, Japan, who were recruited from 1999 to 2003. Logistic regression and Cox hazards models were used to estimate the mortality risk among hemodialysis patients. Among the patients, 422 (14.0%) were positive for HCV RNA. HCV RNA positivity was associated with death in the logistic model (adjusted odds ratio = 1.79; P < 0.001). However, it was not a risk factor for the reduced of survival rate in the Cox proportional hazard model (adjusted risk ratio = 1.07; P = 0.4138). In summary, among hemodialysis patients, HCV RNA is correlated with the mortality rate; however, it is not significantly correlated with prognosis in terms of survival time. On the other hand, diabetes and age at dialysis onset are significantly correlated with survival. Diabetes control treatment should be preferentially selected for hemodialysis patients, and antiviral therapy for HCV should be introduced based on the clinical state of the patient. J. Med.

    This paper examines the dynamics of teh psychotherapeutic relationship between a Maori Elder and Maori psychiatric patients. The functioning of an Elder was examined over a period of 9 months in a psychiatric unit. A content analysis was performed on audiovisual records of 10 interviews conducted by the Elder on five psychiatric patients. The results of this analysis were used to construct a theoretical paradigm of the Elder-Patient Transaction and to contrast it with psychodynamic psychotherapy and pastoral counseling. Distinctive features of relationship, content of the sessions and the issues of dominance and dependence are discussed, and possible mechanisms of change are mentioned. PMID:2587677

    In a prospective study, 80 patients undergoing long-term hemodialysis, 30% more than ten years, were evaluated for joint function and radiographic abnormalities; 58 patients (72%) had clinical symptoms; non-specific arthralgia was the most frequent; 15 patients had inflammatory pain (shoulders 9, hands 3) and diminution of finger mobility (10). Radiological examinations showed 40 abnormal findings in 23 patients (28%): erosive arthropathies of fingers (4), and multiple geodes of the carpus (8), of the humeral head (7) or of the hip (9). We also detected spondylolisthesis (4), erosive arthropathy of cervical (6) or lumbar (2) spine. Pathological study of synovial biopsies was performed in 16 cases. Amyloidosis was found in 4 samples taken routinely. In 2 other cases the biopsy was done on the basis of lesions seen on x-rays: we found amyloidosis in the synovial membrane in both patients and in the bone in one. In 8 patients we found C3 deposits positive in immunofluorescence. These results underline the role of amyloidosis in the mechanism of some arthropathies in long-term hemodialysis patients.

    Aims: The aim of this study focused on serum malondialdehyde (MDA) levels and erythrocyte superoxide dismutase (SOD) and catalase (CAT) activities in hemodialysis patients and compared with control groups. Materials and Methods: Forty-five hemodialyzed patients and 45 control groups recruited in this study. Serum creatinine and urea, thyroid hormones (THs) levels and erythrocyte antioxidant enzyme activities were determined. Results: Hemodialysis (HD) patients showed higher levels of MDA than control groups (P < 0.01), but the levels of thyroxin (T3), free triiodothyronine (fT3), and free thyroxin (fT4), SOD and CAT were low in HD patients (P < 0.01). Serum T3, fT3, and fT4 levels were significantly negative correlated with MDA (P < 0.01). Conclusion: It is concluded that serum lipid peroxidation is markedly increased in HD patients. This means that elevated reactive oxygen species may interact with the lipid molecules in HD patients. HD may cause significant changes in TH levels. Thyroid-stimulating hormone level in HD patients is slightly similar to that of control groups. This suggests that thyroid is able to resynthesize for hormonal urinary losses. PMID:27186552

    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

    Teriparatide, 1-34 parathyroid hormone, is one of effective treatments for osteoporosis. Teriparatide shows an anabolic effect for bone formation, as a result, increases bone mineral density as well as prevention of fractures in the general population. On the other hand, there are a few report about the effect of teriparatide on increase of bone mineral density in maintenance hemodialysis patients. In addition to CKD-MBD, osteoporosis is also an important pathological change in ESRD patients, therefore its safety and efficacy should be discussed in more detail. PMID:27561345

    Background Compared with similarly aged controls, patients with end-stage renal disease (ESRD) have a higher prevalence of cognitive impairment and more rapid cognitive decline, which is not explained by traditional risk factors alone. Since previous small studies suggest an association of cognitive impairment with dialysis modality, we compared incident dementia among patients initiating hemodialysis (HD) versus peritoneal dialysis (PD) in a large national cohort. Methods This is a retrospective cohort study of incident dialysis patients in the United States from 2006 to 2008 with no diagnosis of dementia prior to beginning dialysis. We evaluated the effect of initial dialysis modality on incidence of dementia, diagnosed by Medicare claims data, adjusted for baseline demographic and clinical data from USRDS registry. Results Our analysis included 121,623 patients, of whom 8,663 initiated dialysis on PD. The mean age of our cohort was 69.2 years. Patients who initiated on PD had a lower cumulative incidence of dementia than those who initiated HD (1.0% versus 2.7%, 2.5% versus 5.3%, and 3.9% versus 7.3% at 1, 2, and 3 years, respectively). The risk of dementia for patients who started on PD was lower compared with those who started on HD, with a hazard ratio (HR) = 0.46 [0.41, 0.53], in an unadjusted model and HR 0.74 [0.64, 0.86] in a matched model. Conclusions Dialysis modality is associated with incident dementia in a cohort of older ESRD patients. This finding warrants further investigation of the effect of dialysis modality on cognitive function and evaluation for possible mechanisms. PMID:25742686

    Background Warfarin nomograms to guide dosing have been shown to improve control of the international normalized ratio (INR) in the general outpatient setting. However, the effectiveness of these nomograms in hemodialysis patients is unknown. We evaluated the effectiveness of anticoagulation using an electronic warfarin nomogram administered by nurses in outpatient hemodialysis patients, compared to physician directed therapy. Methods Hemodialysis patients at any of the six outpatient clinics in Calgary, Alberta, treated with warfarin anticoagulation were included. Two five-month time periods were compared: prior to and post implementation of the nomogram. The primary endpoint was adequacy of anticoagulation (proportion of INR measurements within range ± 0.5 units). Results Overall, 67 patients were included in the pre- and 55 in the post-period (with 40 patients in both periods). Using generalized linear mixed models, the adequacy of INR control was similar in both periods for all range INR levels: in detail, range INR 1.5 to 2.5 (pre 93.6% (95% CI: 88.6% - 96.5%); post 95.6% (95% CI: 89.4% - 98.3%); p = 0.95); INR 2.0 to 3.0 (pre 82.2% (95% CI: 77.9% - 85.8%); post 77.4% (95% CI: 72.0% - 82.0%); p = 0.20); and, INR 2.5 to 3.5 (pre 84.3% (95% CI: 59.4% - 95.1%); post 66.8% (95% CI: 39.9% - 86.0%); p = 0.29). The mean number of INR measurements per patient decreased significantly between the pre- (30.5, 95% CI: 27.0 - 34.0) and post- (22.3, 95% CI: 18.4 - 26.1) (p = 0.003) period. There were 3 bleeding events in each of the periods. Conclusions An electronic warfarin anticoagulation nomogram administered by nurses achieved INR control similar to that of physician directed therapy among hemodialysis patients in an outpatient setting, with a significant reduction in frequency of testing. Future controlled trials are required to confirm the efficacy of this nomogram. PMID:21943221

    Background: CD14 is a pattern-recognition receptor that plays a central immunomodulatory role in pro-inflammatory signaling in response to a variety of ligands, including endotoxin. CD14 protein is present in two forms soluble (sCD14) and membrane-bound. Hereby we studied the implications of elevated sCD14 in hemodialysis patients. We hypothesized that sCD14 elevation may link to cytokine activation and protein-energy wasting, predisposing to increased mortality risk. Study Design: Prospective observational study of prevalent hemodialysis patients. Setting & Participants: 211 prevalent hemodialysis patients, median age of 66 years, 29 months of vintage dialysis time followed-up for mortality for a median of 31 months. Predictors: Tertiles of baseline circulating sCD14 corresponding to <2.84, 2.85-3.62, and >3.63 μg/mL, respectively. Outcome: The major outcome of interest was all-cause mortality. Measurements: sCD14 and endotoxin, together with other markers of inflammation and protein-energy wasting. Results: The median value of sCD14 was 3.2 μg/mL (25th to 75th percentile, 2.7 to 3.9). sCD14 correlated positively with C-reactive protein, interleukin-6, endotoxin and long pentraxin-3, while negatively with serum albumin, muscle mass and handgrip strength. Patients with elevated sCD14 had lower body mass index and increased prevalence of muscle atrophy. Patients within the highest sCD14 tertile had a crude morality Hazard ratio of 1.94 (95% CI 1.13-3.32), that persisted after adjustment for multiple confounders (Hazard ratio 3.11 [95% CI 1.49-6.46]). Among patients with persistent inflammation, the presence of concurrent elevation of sCD14 levels gradually increased the mortality risk, but this effect was less than multiplicative and failed to show a statistical interaction. Limitations: Those inherent to an observational study. Conclusions: sCD14 is associated with inflammation and protein-energy wasting in hemodialysis patients. It is a strong and independent

    Surgically created arteriovenous fistulae (AVF) for hemodialysis can contribute to hemodynamic changes. We describe the cases of 2 male patients in whom new right ventricular enlargement developed after an AVF was created for hemodialysis. Patient 1 sustained high-output heart failure solely attributable to the AVF. After AVF banding and subsequent ligation, his heart failure and right ventricular enlargement resolved. In Patient 2, the AVF contributed to new-onset right ventricular enlargement, heart failure, and ascites. His severe pulmonary hypertension was caused by diastolic heart failure, diabetes mellitus, and obstructive sleep apnea. His right ventricular enlargement and heart failure symptoms did not improve after AVF ligation. We think that our report is the first to specifically correlate the echocardiographic finding of right ventricular enlargement with AVF sequelae. Clinicians who treat end-stage renal disease patients should be aware of this potential sequela of AVF creation, particularly in the upper arm. We recommend obtaining preoperative echocardiograms in all patients who will undergo upper-arm AVF creation, so that comparisons can be made postoperatively. Alternative consideration should be given to creating the AVF in the radial artery, because of less shunting and therefore less potential for right-sided heart failure and pulmonary hypertension. A multidisciplinary approach is optimal when selecting patients for AVF banding or ligation.

    Osteoarticular complications, which are characterized by osseous pain, pathologic fractures, and decreased articular mobility, represent one of the major problems affecting long-term (over 15 years) hemodialysis patients. These changes seem to have a multifactorial etiology; they include osteomalacia, secondary hyperparathyroidism, and dialysis-related amyloidosis. Ten patients (5 males and 5 females, mean age 55 +/- 7 years) on long-term (over 15 years) hemodialysis were submitted to X-ray examinations of the skull, spine, shoulders, wrists, pelvis, and knees. Serum calcium, phosphorous, parathyroid hormone, alkaline phosphatase, and basal aluminium levels were also calculated. Osteopenia was demonstrated in all patients. Seven of them had alterations due to hyperparathyroidism. Six patients exhibited signs related to dialysis spondyloarthropathy; in 9 cases amyloid lesions, geodes, and erosions were present in wrists, humeral heads, or hips. One patient exhibited osteomalacic changes. Most long-term dialysis patients presented multifactorial osteoarticular changes due to hyperparathyroidism, osteomalacia, and dialysis-related amyloidosis. Clinical symptoms and decreased articular mobility appeared to be due mainly to amyloid osteoarthropathy.

    Dental services for elderly patients are characterized by a series of particularities related to the vulnerability of this age group, which is affected by various co morbidities, and the diminished physical, cognitive and financial capacities. Finding ways to keep elderly patients coming to a dental office is possible by improving the dentist-patient relationship and implicitly the quality of care by increasing the self-esteem of the elderly and their place in society, by increasing the role of oral health in the quality of life, and here we refer to the pleasure of eating, the pleasant physical aspect and normal diction. The present paper presents the psychological aspects that interfere in the communication process between the dentist and the elderly patient and the changes motivation undergoes when people are in pain. These data can sometimes change the reticent attitude of the dentist towards the elderly patient which is often considered to be a risk patient. PMID:24502052

    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 major 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.

    Inflammation is a common complication in hemodialysis (HD) patients with no valid treatment strategy. In addition, carnitine deficiency occurs frequently in HD patients because of intradialytic loss of carnitine, impaired de novo carnitine renal synthesis, and reduced dietary intake. It appears that carnitine deficiency is related to inflammation in HD patients. A few clinical trials have investigated the effect of L-carnitine supplement on inflammatory markers in HD patients. All studies in this field, except one, showed that L-carnitine could significantly reduce C-reactive protein and serum amyloid A, as two systemic inflammation markers, in HD patients. Therefore, considering high prevalence of inflammation and carnitine deficiency in HD patients, L-carnitine therapy is a reasonable approach for reducing systemic inflammation and its complications in these patients.

    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.

    Abstract The association between dialysis vascular access dysfunction and the risk of developing major adverse cardiovascular events (MACE) in hemodialysis patients is unclear and has not yet been investigated. We analyzed data from the National Health Insurance Research Database of Taiwan to quantify this association. Adopting a case–control design nested within a cohort of patients who received hemodialysis from 2001 to 2010, we identified 9711 incident cases of MACE during the stage of stable maintenance dialysis and 19,422 randomly selected controls matched to cases on age, gender, and duration of dialysis. Events of vascular access dysfunction in the 6-month period before the date of MACE onset (ie, index date) for cases and before index dates for controls were evaluated retrospectively. The presence of vascular access dysfunction was associated with a 1.385-fold higher odds of developing MACE as estimated from the logistic regression analysis. This represents a significantly increased adjusted odds ratio (OR) at 1.268 (95% confidence interval [CI] = 1.186–1.355) after adjustment for comorbidities and calendar years of initiating dialysis. We also noted a significant exposure–response trend (P < 0.001) between the frequency of vascular access dysfunction and MACE, with the greatest risk (adjusted OR = 1.840, 95% CI = 1.549–2.186) noted in patients with ≥3 vascular access events. We concluded that dialysis vascular access dysfunction was significantly associated with an increased risk of MACE. Hence, vascular access failure can be an early sign for MACE in patients receiving maintenance hemodialysis. Active monitoring and treatment of cardiovascular risk factors and related diseases, not merely managing vascular access dysfunction, would be required to reduce the risk of MACE. PMID:26131808

    Iron overload has been described in patients undergoing chronic hemodialysis. The present study was undertaken to evaluate a rapid, noninvasive method for determination of skin iron by the technique of diagnostic x-ray spectrometry (DXS). Thirty-five patients receiving chronic hemodialysis treatment entered the study and were compared with 25 normal controls. Since pathological skin iron deposition occurs mainly at the dermal-epidermal junction in the basal cells of the epidermis, measurements were made in the thenar eminence representing mainly epidermal tissue (FeE), and in the forearm representative mainly of dermis (FeD). The mean +/- SD FeE iron concentrations were equivalent to 14.5 +/- 8.8 and 18.2 +/- 10.2 parts per million wet weight tissue (ppm) and both were significantly higher than in normal controls in which they averaged 9.2 +/- 2.5 ppm (P less than 0.005) and 10.2 +/- 3.2 ppm (P less than 0.001), respectively. There was significant positive correlation between individual skin iron determinations with the total number of blood transfusions received, the rate of blood transfusion, and with serum ferritin levels. Bone marrow hemosiderin was examined in six patients and showed a similar trend. Despite correlation only with indirect indices of tissue iron, our findings suggest that DXS may serve as a reliable quick method for noninvasive estimation of nonreticuloendothelial tissue iron deposition in hemodialysis patients suspected of having transfusional iron overload. The method may be valuable in monitoring the effects of chelation therapy.

    Mineral metabolism affects mortality in hemodialysis patients and is identified by imbalances in serum phosphate (P), calcium (Ca), and parathyroid hormone (PTH). We examined associations between annual mineral values (P, Ca, PTH) and mortality in a 3-year cohort (Dec 2006-2009) of 128,125 hemodialysis patients using three models, that is, baseline, time-dependent and time-average Cox models. We also examined associations between achieved Japanese guideline targets (P: 3.5-6.0 mg/dL, corrected Ca 8.4-10.0 mg/dL, intact PTH 60-180 mg/dL) and all-cause survival to elucidate which parameter should be controlled as a priority. High and low serum P (>6.0 or ≤ 3.5 mg/dL), high Ca (>9.5 mg/dL), higher PTH (>300 pg/mL) and lower PTH (≤ 60 pg/mL) were significantly associated with high mortality in all three models (P < 0.01). When we examined the association between combination of mineral targets and mortality, patients who achieved all targets simultaneously (20% of subjects, reference) showed lowest mortality. Those who achieved both P and Ca targets showed the same mortality as the reference group. Those who only met P target had a lower risk of death (hazard ratio = 1.17) compared to those that achieved Ca or PTH target (1.41, 1.47, respectively). As time of achieving P and Ca targets increased, all-cause mortalities diminished incrementally, significantly. Mineral metabolism disorder would lead to high mortality in prevalent hemodialysis patients. Among mineral values, P would be the strongest predictor for high mortality. Consistent achievement of P and Ca targets would lead to good survival.

    Objectives: To study medicine prescribing pattern for chronic kidney disease (CKD) patients on maintenance hemodialysis. Materials and Methods: This prospective observational study was conducted in hemodialysis unit of a teaching hospital with adult CKD patients on maintenance hemodialysis. Patients’ clinical profile, drug-use pattern, and medication-related problem data were captured in a structured case report form and the data were analyzed descriptively. Adherence level was assessed by Morisky Medication-Taking Adherence Scale 4-item. Results: Data from 100 patients recruited over 6 months have been analyzed. The median (interquartile range [IQR]) age was 51 (42–57) years; 57% were male, mean [standard deviation (SD)] urea level was 160.11 (70.32) mg/dL, mean (SD) creatinine level was 8.73 (5.29) mg/dL. A large number (46%) were suffering from diabetic nephropathy. The common comorbidities were anemia (89%) followed by hypertension (85%). The median (IQR) number of drugs per prescription was 10 (9–13), with the bulk being cardiovascular drugs (23.41%) followed by gastrointestinal drugs (15.76%) and vitamins (12.29%). The median (IQR) number of potential drug-drug interaction per prescription was 2 (2–3). The incidence of adverse drug reactions (ADRs) was 46% with hyponatremia being most common (32%), followed by hypoglycemia (16%) and hypokalemia (10%). Adherence level was low in the majority (64%) of patients. Conclusions: There is a high incidence of polypharmacy along with significant medication-related problems such as high drug-drug interactions/prescription, high incidence of ADRs, and low adherence.

    The cost-effectiveness impact of iron dextran administration on the use of epoetin alfa and blood in hemodialysis patients was studied. Subjects were ambulatory hemodialysis patients who had been receiving hemodialysis for at least six months before the start of an iron dextran protocol and who had been given epoetin alfa for at least four of those six months. Clinical data were collected for six months before and six months after the protocol was implemented. Successful treatment was defined as a hematocrit of 33-36%, a transferrin saturation of >10%, a ferritin concentration of >100 ng/mL, and no blood use except for acute blood loss. A total of 33 patients completed the study. Fifty units of blood were used in the first six months and nine units in the second six months. There was significant improvement in mean hematocrit, ferritin, and transferrin saturation values after the protocol began. Average epoetin alfa doses did not change significantly. There was significant improvement in success rates for ferritin and blood use and in the overall success rate. Ten patients met all success criteria in the preprotocol period, versus 27 in the postprotocol period. Monthly cost-effectiveness analysis for the preprotocol and postprotocol periods indicated costs of $1350 and $526, per successful treatment, respectively. The incremental cost-effectiveness of iron dextran was $42 per successful treatment. Iron dextran improved iron indices and reduced the need for blood transfusions but did not reduce the average dose of epoetin alfa. The additional cost of therapy per month seemed justified by the clinical benefits.

    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

    Uremic pruritus (UP), also known as chronic kidney disease-associated pruritus, is a common and disabling symptom in patients undergoing maintenance hemodialysis (MHD). The pathogenesis of UP is multifactorial and poorly understood. Outdoor air pollution has well-known effects on the health of patients with allergic diseases through an inflammatory process. Air pollution-induced inflammation could occur in the skin and aggravate skin symptoms such as pruritus or impair epidermal barrier function. To assess the role of air pollutants, and other clinical variables on uremic pruritus (UP) in HD patients, we recruited 866 patients on maintenance HD. We analyzed the following variables for association with UP: average previous 12-month and 24-month background concentrations for nitrogen dioxide (NO2) and carbon monoxide (CO), and suspended particulate matter of <2.5 μm (PM2.5). In a multivariate logistic regression, hemodialysis duration, serum ferritin levels, low-density lipoprotein levels, and environmental NO2/CO levels were positively associated with UP, and serum albumin levels were negatively associated with UP. This cross-sectional study showed that air pollutants such as NO2 and CO might be associated with UP in patients with MHD. PMID:27507591

    Klotho is a single-pass transmembrane protein predominantly expressed in the kidney. The extracellular domain of Klotho is subject to ectodomain shedding and is released into the circulation as a soluble form. Soluble Klotho is also generated from alternative splicing of the Klotho gene. In mice, defects in Klotho expression lead to complex phenotypes resembling those observed in dialysis patients. However, the relationship between the level of serum soluble Klotho and overall survival in hemodialysis patients, who exhibit a state of Klotho deficiency, remains to be delineated. Here we prospectively followed a cohort of 63 patients with a mean duration of chronic hemodialysis of 6.7 ± 5.4 years for a median of 65 months. Serum soluble Klotho was detectable in all patients (median 371 pg/mL, interquartile range 309–449). Patients with serum soluble Klotho levels below the lower quartile (<309 pg/mL) had significantly higher cardiovascular and all-cause mortality rates. Furthermore, the higher all-cause mortality persisted even after adjustment for confounders (hazard ratio 4.14, confidence interval 1.29–13.48). We conclude that there may be a threshold for the serum soluble Klotho level associated with a higher risk of mortality. PMID:26604925

    This article reviews the relationship between serum lipids and cardiovascular disease (CVD) in hemodialysis patients. Epidemiologic studies showed a cholesterol paradox in hemodialysis patients, but it can be solved by taking protein-energy wasting and inflammation into consideration. Wasting and inflammation are the risk factors of fatality after incident CVD. Randomized controlled trials showed neutral effects of statins and statin-ezetimibe combination on CVD outcomes in dialysis patients. Current guidelines in Japan recommend that low-density lipoprotein cholesterol (LDL-C) be <120 mg/dL, or non-high-density lipoprotein cholesterol (non-HDL-C) be <150 mg/dL as an alternative target in patients with chronic kidney disease (CKD), whereas Kidney Disease: Improving Global Outcome (KDIGO) guidelines do not recommend any target lipid levels. In addition to "treat to target" and "fire and forget" guidelines, it is possible to recommend that lipid-lowering medication be initiated in certain subgroups of CKD patients. New directions of lipid research in CKD include cholesterol metabolism markers, omega-3 polyunsaturated fatty acids, and modifications of lipoproteins. PMID:24072417

To assess the role of air pollutants, and other clinical variables on uremic pruritus (UP) in HD patients, we recruited 866 patients on maintenance HD. We analyzed the following variables for association with UP: average previous 12-month and 24-month background concentrations for nitrogen dioxide (NO2) and carbon monoxide (CO), and suspended particulate matter of <2.5 μm (PM2.5). In a multivariate logistic regression, hemodialysis duration, serum ferritin levels, low-density lipoprotein levels, and environmental NO2/CO levels were positively associated with UP, and serum albumin levels were negatively associated with UP. This cross-sectional study showed that air pollutants such as NO2 and CO might be associated with UP in patients with MHD. PMID:27507591

    Objective The Roma minority represents the largest ethnic group in Central and South-East European countries. Data regarding the mortality in Roma hemodialysis subjects are limited. We evaluated the 3 year mortality of ESRD Roma patients treated with hemodialysis (HD). Study Design and Setting Our prospective cohort study included 600 ESRD patients on HD therapy recruited from 7 HD centers, from the main geographical regions of Romania. The median age of the patients was 56 (19) years, 332 (55.3%) being males, 51 (8.5%) having Roma ethnicity. Results Roma ESRD patients initiate dialysis at a younger age, 47.8 years vs. 52.3 years (P = 0.017), present higher serum albumin (P = 0.013) and higher serum phosphate levels (P = 0.021). In the Roma group, the overall 3 year mortality was higher when compared to Caucasians (33.3% vs. 24.8%). The multivariate survival analysis revealed that being of Roma ethnicity is an independent risk factor for mortality (HR = 1.74; 95% CI = 1.04–2.91; P = 0.035). Conclusions Roma patients with ESRD initiate HD therapy at a younger age as compared to Caucasians. They have a higher 3 year mortality rate and are dying at a younger age. Roma ethnicity represents an independent risk factor for mortality in our cohort. PMID:27196564

    In order to evaluate the factors that contributed to missed dialysis sessions and increased hospitalizations of hemodialysis patients after Hurricane Katrina, we contacted 386 patients from 9 New Orleans hemodialysis units. Data were collected through structured telephone interviews on socio-demographics, dialysis factors, and evacuation characteristics. Overall, 44% of patients reported missing at least one and almost 17% reported missing 3 or more dialysis sessions. The likelihood of missing 3 or more sessions was greater for those whose dialysis vintage was less than 2 years compared to those for whom it was 5 or more years, who had 38 or fewer billed dialysis sessions compared to those who had 39 or more in the 3 months before the storm, who lived alone before the storm, who were unaware of their dialysis facility's emergency plans, who did not evacuate prior to hurricane landfall, and who were placed in a shelter. The adjusted odds ratio of hospitalization among patients who missed 3 or more compared to those who did not miss any dialysis sessions was 2.16 (95% CI: 1.05-4.43). These findings suggest that when preparing for future disasters more emphasis needs to be placed on patient awareness and early execution of emergency plans.

    The Dialysis Patients Response to IV Iron with Elevated Ferritin (DRIVE) study demonstrated the efficacy of intravenous ferric gluconate to improve hemoglobin levels in anemic hemodialysis patients who were receiving adequate epoetin doses and who had ferritin levels between 500 and 1200 ng/ml and transferrin saturation (TSAT) < or = 25%. The DRIVE-II study reported here was a 6-wk observational extension designed to investigate how ferric gluconate impacted epoetin dosage after DRIVE. During DRIVE-II, treating nephrologists and anemia managers adjusted doses of epoetin and intravenous iron as clinically indicated. By the end of observation, patients in the ferric gluconate group required significantly less epoetin than their DRIVE dose (mean change of -7527 +/- 18,021 IU/wk, P = 0.003), whereas the epoetin dose essentially did not change for patients in the control group (mean change of 649 +/- 19,987 IU/wk, P = 0.809). Mean hemoglobin, TSAT, and serum ferritin levels remained higher in the ferric gluconate group than in the control group (P = 0.062, P < 0.001, and P = 0.014, respectively). Over the entire 12-wk study period (DRIVE plus DRIVE-II), the control group experienced significantly more serious adverse events than the ferric gluconate group (incidence rate ratio = 1.73, P = 0.041). In conclusion, ferric gluconate maintains hemoglobin and allows lower epoetin doses in anemic hemodialysis patients with low TSAT and ferritin levels up to 1200 ng/ml. PMID:18216316

    Ankle fractures in adults are usually managed by open reduction internal fixation. In elderly patients the surgical dilemma relates to bone quality. Osteoporosis is the enemy of internal fixation, and secure purchase of screws in osteopenic bone may be difficult to achieve. Insufficient screw purchase may lead to loss of reduction, wound breakdown, and infection. Postoperative management after osteosynthesis usually requires an extended period of restricted weight bearing. However, this is not feasible in older patients as a result of their lack of strength in the upper extremities and frequent comorbidities. Therefore, augmen- ted methods of internal fixation and specific surgical techniques have been developed using metal and bone cement. This permits this fragile population to begin early full weight bearing in a removable brace. PMID:25752013

    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.

    It has been previously reported that a higher erythropoiesis stimulating agent (ESA) dose in hemodialysis patients is associated with adverse outcomes including mortality; however the causal relationship between ESA and mortality is still hotly debated. We hypothesize ESA dose indeed exhibits a direct linear relationship with mortality in models of association implementing the use of a marginal structural model (MSM), which controls for time-varying confounding and examines causality in the ESA dose-mortality relationship. We conducted a retrospective cohort study of 128 598 adult hemodialysis patients over a 5-year follow-up period to evaluate the association between weekly ESA (epoetin-α) dose and mortality risk. A MSM was used to account for baseline and time-varying covariates especially laboratory measures including hemoglobin level and markers of malnutrition-inflammation status. There was a dose-dependent positive association between weekly epoetin-α doses ≥18 000 U/week and mortality risk. Compared to ESA dose of <6 000 U/week, adjusted odds ratios (95% confidence interval) were 1.02 (0.94–1.10), 1.08 (1.00–1.18), 1.17 (1.06–1.28), 1.27 (1.15–1.41), and 1.52 (1.37–1.69) for ESA dose of 6 000 to <12 000, 12 000 to <18 000, 18 000 to <24 000, 24 000 to <30 000, and ≥30 000 U/week, respectively. High ESA dose may be causally associated with excessive mortality, which is supportive of guidelines which advocate for conservative management of ESA dosing regimen in hemodialysis patients.

    2010-01-01

    Background Left ventricular (LV) hypertrophy is common among patients on hemodialysis. While a relationship between blood pressure (BP) and LV hypertrophy has been established, it is unclear which BP measurement method is the strongest correlate of LV hypertrophy. We sought to determine agreement between various blood pressure measurement methods, as well as identify which method was the strongest correlate of LV hypertrophy among patients on hemodialysis. Methods This was a post-hoc analysis of data from a randomized controlled trial. We evaluated the agreement between seven BP measurement methods: standardized measurement at baseline; single pre- and post-dialysis, as well as mean intra-dialytic measurement at baseline; and cumulative pre-, intra- and post-dialysis readings (an average of 12 monthly readings based on a single day per month). Agreement was assessed using Lin's concordance correlation coefficient (CCC) and the Bland Altman method. Association between BP measurement method and LV hypertrophy on baseline cardiac MRI was determined using receiver operating characteristic curves and area under the curve (AUC). Results Agreement between BP measurement methods in the 39 patients on hemodialysis varied considerably, from a CCC of 0.35 to 0.94, with overlapping 95% confidence intervals. Pre-dialysis measurements were the weakest predictors of LV hypertrophy while standardized, post- and inter-dialytic measurements had similar and strong (AUC 0.79 to 0.80) predictive power for LV hypertrophy. Conclusions A single standardized BP has strong predictive power for LV hypertrophy and performs just as well as more resource intensive cumulative measurements, whereas pre-dialysis blood pressure measurements have the weakest predictive power for LV hypertrophy. Current guidelines, which recommend using pre-dialysis measurements, should be revisited to confirm these results. PMID:20576127

    Low vitamin D levels have been linked to metabolic syndrome in the general population. In the present study, the relationship between inadequate serum concentrations of vitamin D and metabolic syndrome in patients with end-stage renal disease undergoing hemodialysis was explored. In a cross-sectional setting, 145 patients undergoing maintenance hemodialysis were enrolled. Metabolic syndrome was defined using the International Diabetes Federation criteria. Serum concentration of 25(OH) vitamin D was determined by a commercially available enzyme immunosorbent assay method. The prevalence of metabolic syndrome was 53.1%. The prevalence rate of severe vitamin D deficiency (<5 ng/mL) was 3.4%, mild vitamin D deficiency (5-15 ng/mL) 31.0%, vitamin D insufficiency (16-30 ng/mL) 36.6%, and vitamin D sufficiency (>30 ng/mL) 29.0%. With the increasing number of metabolic abnormalities, vitamin D levels significantly decreased (P for trend = 0.028). Among the components of metabolic syndrome, vitamin D deficiency was significantly associated with central obesity (odds ratio [OR], 95% confident interval [CI] = 2.80, 1.11-7.04, P = 0.028). A positive, but nonsignificant association between vitamin D deficiency and raised fasting plasma glucose was noted (OR, 95% CI = 2.40, 0.94-6.11, P = 0.067). Both vitamin D deficiency and insufficiency were significantly associated with an increased likelihood of having metabolic syndrome (P < 0.05). In a final model controlling for age, sex, and parathyroid hormone levels, vitamin D deficiency increased the odds of having metabolic syndrome by more than threefold (OR, 95% CI = 3.26, 1.30-8.20, P = 0.012). Low levels of vitamin D are frequent among hemodialysis patients and are associated with the metabolic syndrome.

    Plasma aluminum (pAl) was measured in 58 patients coming from three centers using different preparation of dialysis water: deionizer (29 patients), softener (16 patients) and reverse osmosis (13 patients). Twenty five healthy subjects were used as controls. A deferoxamine test was performed to 11 of 19 patients with pAl between 40 and 200 micrograms/dl and a bone biopsy with double tetracycline staining was executed to 15 patients with pAl over 40 micrograms/dl. Mean pAl was 9.5 +/- 1.7 micrograms/dl in controls and 34.3 +/- 6.1 169 +/- 27.8 and 50.8 +/- 10.3 micrograms/dl in patients coming form centers using deionizers, softeners and reverse osmosis respectively. Seventy six percent of patients coming from centers using deionizers and 85% of patients coming from centers with reverse osmosis had pAl below 40 micrograms/dl and all had values below 200 micrograms/dl. Plasma aluminum had a increase of over 200 micrograms/dl in 6 of 11 patients in which the deferoxamine test was performed. Six patients had a positive staining for aluminum in bone biopsies (three with basal pAl over 200 micrograms/dl and one with a increase in pAL after deferoxamine < 200 micrograms/dl). Of these, 2 patients had a mixed osteodystrophy and 4 a low turnover bone disease. Centers with deionizers and reverse osmosis had very low aluminum levels in dialysis water and five of six patients with aluminum levels related bone disease came from the center using softener.

    Patients on a chronic hemodialysis regimen were studied with respect to their erythrocyte adaptation to anemia. Erythrocyte 2,3-diphosphoglycerate (DPG) concentration was suboptimal compared with that of anemic patients who were not uremic. In uremic patients erythrocyte 2,3-DPG correlated poorly with hemoglobin level but more strongly with plasma pH. Differences between observed levels of erythrocyte 2,3-DPG and the values predicted using data from other anemic patients also correlated with pH. Gradual correction of plasma pH with oral sodium bicarbonate resulted in a substantial increase in erythrocyte 2,3-DPG and a decrease in oxygen affinity. Therefore, maintenance of normal pH in uremic subjects may improve tissue oxygenation. On the other hand, the rapid correction of acidosis during dialysis resulted in increased oxygen affinity. This response was due to the direct effect of pH on oxygen affinity in the absence of a significant change in erythrocyte 2,3-DPG or adenosine triphosphate (ATP) during hemodialysis. Erythrocyte ATP but not 2,3-DPG correlated with serum inorganic phosphate in uremic subjects. A 21% reduction of serum phosphate produced by ingestion of aluminum hydroxide gel had no significant effect on these variables.

    Objective To assess microorganisms associated with vascular access-associated infections (VAIs) in hemodialysis patients, with respect to possible origin from the mouth. Study Design A retrospective and comparative analysis of the microbes associated with VAI in hemodialysis patients treated during a 10-year period was performed using the Human Oral Microbiome Database (HOMD). Results Of 218 patient records identified, 65 patients collectively experienced 115 VAI episodes. The most common microorganisms involved were Staphylococcus aureus (49.6% of infections), Staphylococcus epidermidis (10.4%), Serratia marcescens (10.4%), Pseudomonas aeruginosa (9.6%), and Enterococcus faecalis / fecum (8.7%). None of these was found in 1% or more of HOMD clone libraries, indicating that they very rarely colonize the teeth or plaque. Conclusions Most VAIs were associated with microorganisms more likely to originate from other body sites than from the oral cavity. The risk of a VAI being caused by microorganisms originating from the oral cavity is very small. PMID:23217535

    The aim of this study was to investigate the impacts of parathyroidectomy (PTX) towards the renal anemia and nutritional status of hemodialysis patients with secondary hyperparathyroidism (SHPT). 32 patients, enrolled into the blood purification center of our hospital for the hemodialysis treatment, were collected and divided into the PTX group and the non-PTX group, with 16 patients in each group. The changes of relevant indicators such as immunoreactive parathyroid hormone (iPTH), anemia and nutrition were observed before, 1-, 3-, 6-month after the treatment. The contents of iPTH, Ca, P and Ca × P of the PTX group decreased rapidly 1 month after the surgery; while Hb and Hct increased significantly from the 1st postoperative month; the dosage of EPO was significantly reduced 3-month after the surgery; the content of Alb gradually increased from the 3(rd) postoperative month; the content of TG decreased significantly from the 6(th) postoperative month; while the contents of BMI and TSF increased significantly from the 6(th) postoperative month, which exhibited the statistically significant differences when compared with the preoperative and the non-PTX group (P < 0.05). PTX could quickly reduce the iPTH level and significantly improve the renal anemia and nutritional status; SHPT was the important factor that would affect the renal anemia and malnutrition; PTX could reduce the amount of EPO, and reduce the economic burden of patients.

    Uric acid accumulates in renal failure and is thought to be a uremic toxin—that is, higher levels of uric acid are more damaging to the kidneys. Urate crystals can precipitate in the kidney tubules, cause urate stones, and promote inflammatory changes in the renal interstitium and vascular endothelium. Uric acid is also a small non-protein-bound molecule and therefore easily dialyzable. Here, we present the case of an anuric hemodialysis patient with severe tophaceous gout who regained some renal function and whose gout burden significantly decreased resulting in marked improvement in functional status using a new gout medication, febuxostat, and increased frequency of dialysis.

He presented with life-threatening hematemesis, secondary to esophageal rupture. Immunohistological staining and electron microscopy examination of the esophageal perforation showed depositions of beta 2-microglobulin (beta 2-M) amyoloid. The unique aspect presented here is the localized esophageal involvement with beta 2-M amyloidosis. This is the first reported patient with esophageal perforation, due to the deposition and infiltration of the lower esophagus with beta 2-M which predisposed to its rupture. PMID:9426849

    Background: Occurrence of hypotension during hemodialysis in nearly 20-30% of patients, shows is the necessity of continuous monitoring the patients' blood pressure during hemodialysis. Since directly and non-invasively continuous blood pressure monitoring, is not easy, finding a parameter related to blood pressure, for indirect monitoring is of great value. Related blood volume (RBV) is one of the parameters, related to blood pressure and have a good potential to reflect the patient’s hemodynamic condition. Objectives: The main objective of this study was to design and construct an optical device to determine the RBV in patients undergoing hemodialysis, during the process. Materials and Methods: After initial studies in order to select a proper sensor, using the ORCAD software, an analog circuit was designed. The implementation and modification of the circuit was done by the clinical tests, using expired blood. Afterwards, for calculation the RBV, controlling the display, data storage and sending it to the computer, an ATmega16 microcontroller was used. For programing the microcontroller, CodeVision software and then Altium Designer software were used for the circuit compression, in order to design the printed circuit board. Finally, all parts of the analog and digital circuit, AC to DC converter and the LCD were embedded in a box. Results: After finalization of the device and before testing it in a real situation, expired blood was used for final evaluation. The evaluation was done by changing the blood concentration, at the start point by adding water to it. In fact, the device can track the changes in blood concentration and display the RBV. After this evaluation, the device was tested in a clinical situation. The results showed there are no interactions between this device and the other devices used in the dialysis section and it can work properly in order to measure the RBV. Conclusions: Considering the hypotension and its consequences in a patient on

    Anemia is a frequent complication in hemodialysis patients. Compared to conventional hemodialysis (CHD), short daily hemodialysis (sDHD) has been reported to be effective in many countries except China. The aim of the present study was to determine whether sDHD could improve anemia and quality of life (QOL) for Chinese outpatients with end-stage renal disease. Twenty-seven patients (16 males/11 females) were converted from CHD to sDHD. All laboratory values were measured before conversion (baseline), at 3 months after conversion (sDHD1), and at 6 months after conversion (sDHD2). The patient's QOL was evaluated at baseline and 6 months after conversion using the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36). Hemoglobin concentration increased significantly from 107.4 ± 7.9 g/L at baseline to 114.4 ± 6.8 g/L (P<0.05) at sDHD1, and 118.3±8.4 g/L (P<0.001) at sDHD2 (Student paired t-test). However, the dose requirement for erythropoietin decreased from 6847.8 ± 1057.3 U/week at baseline to 5869.6±1094.6 U/week (P<0.05) at sDHD2. Weekly stdKt/V increased significantly from 2.05±0.13 at baseline to 2.73±0.20 (P<0.001) at sDHD1, and 2.84±0.26 (P<0.001) at sDHD2. C-reactive protein decreased from baseline to sDHD1 and sDHD2, but without statistically significant differences. Physical and mental health survey scores increased in the 6 months following conversion to sDHD. sDHD may increase hemoglobin levels, decrease exogenous erythropoietin dose requirements, and improve QOL in Chinese hemodialysis patients compared to CHD. A possible mechanism for improvement of clinical outcomes may be optimized management of uremia associated with the higher efficiency of sDHD.

    The presence of peritoneal implants detected by computered axial tomography (CT) is usually related to mesothelial primary neoformative processes or, more frequently to peritoneal metastasis or peritoneal carcinomatosis. Although the higher prevalence of neoplastic processes in the chronic renal failure population, the association of peritoneal implants and constitutional syndrome is not always correlated to peritoneal carcinomatosis. We present the case of two patients with chronic renal failure in hemodialysis programme, with abdominal insidious clinical, constitutional syndrome and similar peritoneal implants seen by CAT: the histologic analysis of peritoneal implants gave the definitive diagnostic of secondary amyloidosis and peritoneal tuberculosis respectively.

    Depression is common in patients with end-stage renal disease (ESRD) and is associated with increased mortality and morbidity. Several investigators have estimated that depression occurs in about 20% to 30% of dialysis patients. The aim of this study was to investigate the relationship between depression, some laboratory parameters, and quality of life (QOL) in hemodialysis patients. Forty-three hemodialysis patients (mean age 40.5+/-15.2; M=28, F=15) were included in the study. Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), and short form with 36 (SF-36) were used for evaluation. Subsequently, patients were divided into two groups according to HAMD scores: group 1, those who had a low HAMD score (between 0 and 7), and group 2, those who had a high HAMD score (over 7). The two groups were compared in terms of anxiety scores, QOL scores, and some laboratory parameters. The group 2 patients (n=21; M= 13, F=8) had lower levels of hemoglobin than the group 1 patients (9.5+/-1.7 vs. 10.7+/- 1.4 g/dL, respectively; p<0.01). Group 2 patients also had lower SF-36 scores than group 1 patients (91.5+/-21.3 vs. 74.9+/- 13.6, respectively; p=0.03). On the contrary, the patients of group 2 had higher HAMA scores than group 1 patients (16.6+/-6.9 vs. 6.3+/-3.5, respectively; p<0.01) and CRP level (10.7+/-4.6 vs. 4.5+/-3.8, respectively; p<0.001). A significant correlation was found between depression scores and C-reactive protein (CRP) (r= 0.57, p < 0.001) and HAMA scores (r=-0.43, p<0.05). In contrast, a negative correlation was found between HAMD scores and albumin (r=-0.43, p<0.05), hemoglobin (r=-0.38, p=0.015) and SF-36 scores (r=0.39, p=0.032). These findings demonstrate that there is a relationship among high depression score, low levels of hemoglobin and albumin, high CRP level, low SF-36 score, and high anxiety score. Evaluation of psychiatric status should be part of the care provided to hemodialysis patients.

    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. 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

    Introduction: 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. Method & Material: 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. Result: Significant differences were observed between the two groups in the posttest regarding the dimensions scores of DASS scale. Conclusion: 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.

    Background: Nutritional barriers may contribute to malnutrition in hemodialysis (HD) patients. Higher rates of morbidity and mortality rates have been reported in malnourished HD patients. These patients are faced with different challenges affecting their nutritional status. Objectives: The aim of this cross-sectional study was to identify most important barriers responsible for malnutrition in HD patients. Patients and Methods: We randomly selected 255 of 800 stable HD patients from three HD centers with an age range of 18-85 years, who had been on hemodialysis for at least three months without any acute illness. Each patient was interviewed to evaluate malnutrition [subjective global assessment (SGA), malnutrition inflammation score (MIS)], and potential medical, behavioral and socioeconomic barriers. Body composition of patients was checked through bioelectrical impedance analysis (BIA). Routine clinical markers of malnutrition such as serum albumin and total protein were measured using standard automated techniques. Binary logistic regression model was used to find the association between nutritional markers and potential barriers. Results: Patients with higher SGA had lower knowledge about general nutrition [odds ratio (OR), 1.3], potassium (OR, 1.89), difficulty chewing (OR, 1.16), and shopping (OR, 1.16). Those with greater MIS scores had poor appetite (OR, 1.3), depression (OR, 1.21), and difficulty with cooking (OR, 1.15). Lower BCM (body cell mass) was associated with poor appetite (OR, 0.92) and needed help for cooking (OR, 0.88). Patients with higher BFMI (body fat mass index) had insufficient general nutrition (OR, 1.15), and protein (OR, 1.27) knowledge, and needed help for shopping (OR, 1.14). Moreover, patients with higher SGA scores were those with older age and longer duration of HD. Conclusions: Three medical barriers (poor appetite, depression and difficulty chewing), one behavioral barrier (poor total nutrition, protein, and potassium knowledge

    The role of nephrologists as de facto primary care providers (PCP) for dialysis patients is of increasing interest. We sought to determine the proportion of patients who rely on nephrologists for primary care and to identify demographic variables associated with this primary care responsibility. We reviewed the charts of 158 patients receiving hemodialysis at a suburban, freestanding, teaching hospital affiliated outpatient unit from December 1999 through January 2001. In addition, each patient was interviewed and completed a survey. Non-nephrologists were considered to be a patient's PCP if there was chart, survey or interview evidence of such a relationship. Of the 158 patients, only 56 patients had a PCP. The nephrologist thus was the de facto PCP in 65% of hemodialysis patients, a responsibility that was 3.3-fold more likely for patients not enrolled in a health maintenance organization (HMO) or managed care organization (MCO). In the non-HMO/MCO group, patients with a PCP had been on dialysis for less time than those without a PCP [2.7 vs. 4.6 years (P=0.0006)]. Only 32% of patients on dialysis <1 year had nephrologists as de facto PCP vs. 71% of those on dialysis more than 1 year (P=0.0002). This association between time on dialysis and de facto use of nephrologists as PCP was not accounted for by the shorter time on dialysis of HMO/MCO enrollees. The extent to which the nephrologist fulfills the often unsought role as PCP needs further investigation. PMID:16132772

    Thyroid function test values are generally at low levels in patients with end-stage kidney disease. Life-threatening thyrotoxicosis or thyroid storm is rare, especially in hemodialysis (HD) patients, and is characterized by multisystem involvement and a high mortality rate if not immediately recognized and treated. Here, we report a female patient with severe symptomatic thyroid storm, receiving long-term HD and glucocorticoid therapy. Methimazole at a dose of 15 mg per day, β-adrenergic blockade and HD succeeded in controlling the patient's condition by gradually adjusting the target dry weight for hyperthyroidism-induced weight loss. When she was discharged from the hospital, her dry weight was reduced from 47.2 to 39.2 kg. The management of patients with severe symptomatic thyroid storm on HD represents a rare scenario. It is essential to initiate the available treatments as early as possible to reduce its mortality. PMID:23197948

    Hemodialysis has improved the morbidity and mortality associated with end stage renal disease. In India, hemodialysis prescription is empiric, which leads to complications related to under-dialysis. Hence, adequacy of hemodialysis in Indian setting was analyzed in this study. A total of 50 patients on twice per week hemodialysis were assessed for 1 month. The number of sessions meeting standards laid out by Kidney Diseases Outcome Quality Initiatives (KDOQI) guidelines were calculated. They were divided into two groups: one in whom dialysis was monitored and session length enhanced to meet the minimum standard Kt/V of 2 and second control group; where Kt/V was not monitored. Hemoglobin (Hb) levels, albumin levels, mean arterial pressure and World Health Organization (WHO) quality of life (QoL) score were compared in the two groups after 6 months. Only 28% of hemodialysis sessions were adequate as per KDOQI guidelines. There was significant improvement in Hb levels (1.47 vs. 0.15 g/dl), mean arterial pressure levels (15.2 vs. 3.16 mm Hg), serum albumin levels (0.82 vs. 0.11 g/dl) and WHO QoL score (17.2 vs. 2.24) in study group as compared to control group. Standard Kt/V can be used as an important tool to modify twice weekly dialysis sessions to provide better QoL to the patients. However, studies with larger sample size are required to conclusively prove our results.

    Background The U.S. Centers for Medicare & Medicaid Services (CMS) assesses patient experiences of care as part of the End Stage Renal Disease (ESRD) Prospective Payment System and Quality Incentive Program. This article describes the development and evaluation of the Consumer Assessment of Healthcare Providers and Systems In-Center Hemodialysis survey (CAHPS® ICH survey). Study Design We conducted formative research to generate survey questions and conducted statistical analyses of survey responses to evaluate the survey’s measurement properties. Setting and Participants Formative research included 5 focus groups (2 with hemodialysis patients, 2 with caregivers, 1 with nephrologists) and 56 cognitive interviews with dialysis patients. We collected field test responses to the survey from 1454 dialysis patients receiving care at 32 facilities. Measurements & Outcomes We assessed the CAHPS ICH Survey. Results Response rate was 46%. Analyses support 3 multi-item scales: Nephrologists’ Communication and Caring (7 items, Cronbach’s alpha = 0.89); Quality of Dialysis Center Care and Operations (22 items, alpha = 0.93); and, Providing Information to Patients (11 items, alpha = 0.75). The communication scale was the most strongly correlated with the global rating of the ‘kidney doctor’ (r = 0.78). The Dialysis Center Care and Operations scale was most strongly correlated with the global ratings of staff (r = 0.75) and of the center (r = 0.69). Providing Information to Patients was most strongly correlated with the global rating of the staff (r=0.41). Limitations Males and younger patients were over-represented in the field test compared to the general U.S. population of dialysis patients. A relatively small number of patients completed the survey in Spanish. Conclusions This study provides support for the reliability and validity of the CAHPS ICH survey for assessing ESRD patient experiences of care at dialysis facilities. The survey can be used to compare care

    The presence of Helicobacter pylori (HP) infection may adversely influence outcome in renal transplant candidates because of its strong association with gastrointestinal disorders. We examined the association between HP infection and nutritional parameters in symptom-free hemodialysis patients and assessed prospectively the nutritional changes in patients who received therapy for the disease. The 163 study patients, including 114 men and 69 women of mean age 41.5 +/- 12.9 years on dialysis for 67.2 +/- 47.6 months, were selected from among the group who underwent routine endoscopic evaluation according to our renal transplant protocol. Patients with active peptic ulcer, acute gastritis, chronic inflammatory disease, malignancy, or diabetes mellitus were excluded. Endoscopy results revealed normal findings in 60 (group 1), gastritis in 86 (group 2), or gastritis with HP in 17 patients (group 3). Group 3 patients received a 2-week course of triple therapy (omeprazole, amoxicillin, clarithromycin). The patient groups were compared for nutritional metrics (albumin, phosphorus, interdialytic weight gain [IDWG], body mass index [BMI]), inflammatory indices (CRP, fibrinogen), and iPTH levels. Group 3 patients were observed to be malnourished when compared with groups 1 and 2, namely abnormal values of albumin (P <.0001), phosphorus (P <.009), IDWG (P <.03), and BMI (P <.02). Repeat endoscopy revealed a 94% rate of eradication of HP with increased levels of albumin and phosphorus in group 3. Although symptom-free hemodialysis patients with HP-associated gastritis displayed a state of malnutrition; its eradication improved the nutritional status. Therefore, the presence of HP infection should be sought and its eradication mandatory for this patient population.

    Background and study aims: Small intestinal pathology in hemodialysis (HD) patients has been studied in only a small number of retrospective case series. One method for noninvasively surveying small intestinal disorders is video capsule endoscopy (VCE). The primary aim of this study was to investigate the prevalence of small intestinal abnormalities among asymptomatic maintenance HD outpatients using VCE. The secondary aim was to assess the clinical impact of these abnormalities. Patients and methods: This study consisted of two phases. In phase I, a cross-sectional study, a cohort of patients who received maintenance HD three times weekly at an outpatient hemodialysis clinic were studied using VCE. Phase II was a prospective cohort study with follow up for 1 year after VCE. Results: Fifty-six patients were enrolled in this study, and two were excluded from analysis due to capsule retention in the stomach. The prevalence of small bowel abnormalities in HD patients was 64.8 % (35/54) (95 % confidential interval 52.1 % – 77.6 %). Of 54 patients, 21 (38.9 %) had mucosal lesions, 10 (18.5 %) had vascular lesions, and 4 (7.4 %) had both lesion types. During the 1-year follow-up period, events occurred in four patients. A small bowel-associated event was observed in one patient, who underwent laparoscopy-assisted small intestinal partial resection 3 months after diagnosis by VCE. All patients in whom events were seen had small bowel abnormalities; no events were observed in the VCE-negative group. Conclusions: Although asymptomatic maintenance HD patients had a high prevalence of small bowel abnormalities (64.8 %), they did not have a high incidence of small bowel-associated events during the 1-year follow-up.

    Ghrelin abnormalities contribute to anorexia, inflammation, and cardiovascular risk in hemodialysis patients, leading to worse outcome. However, ghrelin levels are influenced by the nutritional status of the individual. We hypothesized that the consequences of ghrelin alterations in hemodialysis patients are context sensitive and dependent on the presence of protein-energy wasting (PEW). In this cross-sectional study of 217 prevalent hemodialysis patients followed for 31 months, we measured ghrelin, leptin, PEW (subjective global assessment), and C-reactive protein (an index of inflammation). Compared to patients in the middle and upper tertile of ghrelin levels, those in the lowest tertile were older, had higher leptin levels and body mass index, and presented an increased mortality risk that persisted after adjustment for age, gender, and dialysis vintage. This risk was lost after correction for comorbidities. Patients with PEW and low ghrelin values had abnormally high C-reactive protein and leptin by multivariate analysis of variance, and the highest mortality risk compared to non-PEW with high ghrelin from all-cause and cardiovascular-related mortality (adjusted hazard ratios of 3.34 and 3.54, respectively). Low ghrelin values in protein-energy wasted hemodialysis patients were linked to a markedly increased cardiovascular mortality risk. Thus, since these patients were more anorectic, our results provide a clinical scenario where ghrelin therapies may be particularly useful.

    Background. Increased oxidative stress is a well described feature of patients in hemodialysis. Their need for multiple blood transfusions and supplemental iron causes a significant iron overload that has recently been associated with increased oxidation of polyunsaturated lipids and accelerated aging due to DNA damage caused by telomere shortening. Methods. A total of 70 patients were evaluated concomitantly, 35 volunteers with ferritin levels below 500 ng/mL (Group A) and 35 volunteers with ferritin levels higher than 500 ng/mL (Group B). A sample of venous blood was taken to extract DNA from leukocytes and to measure relative telomere length by real-time PCR. Results. Patients in Group B had significantly higher plasma TBARS (p = 0.008), carbonyls (p = 0.0004), and urea (p = 0.02) compared with those in Group A. Telomeres were significantly shorter in Group B, 0.66 (SD, 0.051), compared with 0.75 (SD, 0.155) in Group A (p = 0.0017). We observed a statistically significant association between relative telomere length and ferritin levels (r = −0.37, p = 0.001). Relative telomere length was inversely related to time on hemodialysis (r = −0.27, p = 0.02). Conclusions. Our findings demonstrate that iron overload was associated with increased levels of oxidative stress and shorter relative telomere length. PMID:27800120

    Non-O1, and non-O139 Vibrio cholerae is an infrequent cause of bacteremia. There are no reports of such bacteremia in chronic hemodialysis patients. This work describes the case of a chronic hemodialysis patient that had an episode of septicemia associated with dialysis. Blood cultures were obtained and treatment was begun with vancomycin and ceftazidime. After 6.5 hours of incubation in the Bact/Alert system there is evidence of gram-negative curved bacilli that were identified as Vibrio cholerae by conventional biochemical tests, API 20 NE and the VITEK 2 system. This microorganism was sent to the reference laboratory for evaluation of serogroup and virulence factors and was identified as belonging to the non-O1 and non-O139 serogroup. The cholera toxin, colonization factor and heat-stable toxin were not detected. The isolate was susceptible to ampicillin, trimethoprim-sulfamethoxazole, ciprofloxacin, tetracycline, ceftazidime and cefotaxime by the disk diffusion method and the VITEK 2 system. The patient received intravenous ceftazidime for a 14 day- period and had a favorable outcome.

    Intradialytic exercise-induced blood volume (BV) reduction may cause intradialytic hypotension in hemodialysis (HD) patients. However, BV recovery time after intradialytic exercise remains unknown. Hemodialysis patients were recruited, and their relative BV change (%ΔBV) were measured with intradialytic exercise (n = 12). After confirming the linearity of %ΔBV for 30 min, patients exercised using a stationary cycle in the supine position. The target exercise intensity was a 10% increase in heart rate (HR), corresponding to relatively low-intensity exercise. Baseline %ΔBV (assumed baseline) were calculated for the 30 min before exercise using linear regression analysis. The mean intradialytic exercise start and end times after HD initiation were 93.0 ± 8.4 and 116.4 ± 8.3 min, respectively, a mean exercise duration of 23.5 ± 2.6 min. Percentage change in blood volume declined rapidly upon exercise initiation and gradually increased above the assumed baseline throughout HD. At the end of HD, %ΔBV in the exercise group was significantly higher than the assumed baseline (measured - assumed baseline %ΔBV: 2.17 ± 0.62%; p = 0.02). Intradialytic exercise with low intensity in the supine position attenuated ultrafiltration-induced BV reduction at the end of HD. Therefore, intradialytic exercise may prevent intradialytic hypotension during later HD, although its intensity was relatively low level. PMID:26720736

    Background: Inflammatory and procoagulant markers are potential mediators for the cardiovascular risk in hemodialysis patients. Lipoprotein (a) [Lp(a)], is another important risk factor with inflammatory and procoagulant effects. Materials and methods: In 78 hemodialysis patients and 40 controls, C-reactive protein (CRP), Interleukin-6 (IL-6), lipoprotein (a) [Lp (a)], fibrinogen, D-dimer, von Wilebrand factor (vWF) and serum albumin were determined. Results: CRP, IL-6, Lp(a), fibrinogen, D-dimer and vWF, were significantly higher, and serum albumin was significantly lower in patients compared to controls (24.40 mg/L vs. 6.39 mg/L, p<0.001; 1.92 pg/ml vs. 0.35 pg/ml, 28.05 mg/dL vs.16.25 mg/dL, p<0.001; 3.44 g/L vs. 2.55 g/L, p<0.01; 1.81 µgFEU /ml vs. 0.50 µgFEU /ml, p<0.01; 152.9 % vs. 85.6 %, p<0.001; 32.1 g/L vs. 40.50 g/L, p<0.001). The patients were divided into two groups: 40 patients with CRP levels over than 10 mg/L and 38 with CRP levels in normal range. These parameters showed significant differences between patients with elevated CRP and patients with normal CRP levels. CRP and IL-6 correlated positively with Lp(a), (r = 0.62, p < 0.001; r=0.54, p<0.001), fibrinogen, (r = 0.63, p < 0.001; r = 0.49, p<0.01) D dimer (r = 0.72, p<0.001; r = 0.55, p<0.01), vWF (r = 0.76, p<0.01; r = 0.63, p<0.001) and negatively with serum albumin (r = -0.80, p<0.01; r = -0.60, p<0.001), in patients with elevated CRP, but not in patients with normal CRP levels and controls. Conclusion: According to the results hemodialysis patients with increased inflammatory markers, have the elevated Lp(a) and procoagulant markers and the greater risk for atherosclerotic cardiovascular disease.

    Bladder cancer (BCa) is a disease of the elderly and as the population is aging, BCa will become an even bigger public health challenge in the future. Nowadays the correct management of BCa in the elderly remains controversial. The purpose of this article was to review the previous literature to summarize the current knowledge. Using Medline, a non-systematic review was performed including articles between January 2000 and February 2016 in order to describe the management of BCa in the elderly in all its aspects. English language original articles, reviews and editorials were selected based on their clinical relevance. In the literature, the definition of elderly is variable and based on chronological, not biological, age. BCa seems to be more aggressive in the elderly. The management of non-muscle invasive bladder cancer (NMIBC) does not strongly differ from younger patients, except for the role of adjuvant immunotherapy. In patients with muscle invasive bladder cancer (MIBC) the role of a multidisciplinary geriatric evaluation is potentially beneficial. The curative treatment in MIBC remains radical cystectomy (RC) and elderly patients should not be withheld a potentially life-saving intervention only based on chronological age. Patients unsuitable to a major surgical approach may be eligible for bladder-sparing techniques. Geriatric assessment could help identify the frail elderly and customize their perioperative care (i.e., pre and re habilitation). In conclusion the treatment of BCa in the elderly has to be patient-centered and focused on biological age and functional reserves.

    The mortality rate for malignant melanoma is higher in elderly patients aged 75 years or more, with over 25% of melanomas being diagnosed in this population. This poorer prognosis might perhaps be improved by emerging targeted therapies and immunotherapy, although these agents must be prescribed with care in this rather fragile population. The purpose of our review of the literature concerning phase-2 and -3 published trials of these innovative molecules was to examine their optimal use in elderly patients presenting metastatic malignant melanoma. Most of the trials examined included elderly patients and some were analyzed by age sub-groups. In conclusion, elderly patients with ECOG 0/1 status can be given ipilimumab or vemurafenib as first-line therapy depending on tumoral BRaf mutation status. The benefit of combined targeted therapies does not seem to apply consistently in elderly patients and their use must be discussed. Further specific data must be collected in elderly patients concerning anti-PD1 molecules. For more fragile patients, risk scales or scores should enable more accurate use of innovative therapies in metastatic melanoma. Moreover, physicians must be aware of the common drug interactions with targeted therapies, since elderly patients are often taking several concomitant drugs.

    We determined the prevalence of hepatitis C virus (HCV) in hemodialysis patients by antibody testing and HCV RNA determination by PCR. A total of 149 patients with kidney failure with replacement therapy were tested. The prevalence of anti-HCV was 6.7% (10 of 149 patients), and viremia was detectable in 8 of 149 (5%) patients. Three of 149 patients (2%) were anti-HCV negative with detectable HCV RNA.

    Treatment for prostate cancer (PCa) has evolved significantly over the last decade. PCa is the most prevalent non-skin cancer and the second leading cause of cancer death in men, and it has an increased incidence and prevalence in older men. As a result, physicians and patients are faced with the challenge of identifying optimal treatment strategies for localized, biochemical recurrent, and advanced PCa in the older population. When older patients are appropriately selected, treatment for PCa results in survival benefits and toxicity profiles similar to those experienced in younger patients. However, underlying health status and age-related changes can have an impact on tolerance of hormonal therapy and chemotherapy in men with advanced disease. Therefore, the heterogeneity of the elderly population necessitates a multidimensional assessment to maximize the benefit of medical and/or surgical options. Providing clinicians with the requisite health status data on which to base treatment decisions would help ensure that older patients with PCa receive optimal therapy if it will benefit them and/or active surveillance or best supportive care if it will not. We provide a review of the existing evidence to date on the management of PCa in the older population. PMID:25071137

    Some patients undergoing periodic hemodialysis have complained that between one treatment session and the next they suffer form thirst and have serious problems in maintaining their interdialytic weight gain within the limits indicated by the medical team. Weight gain may usually be explained by psychological factors: they may be more or less acute depending on the situation in which the patient finds himself. On the basis of the present study, the Authors affirm that the lack of interdialytic weight control may be easily improved by providing the patient with psychological support capable of optimising his general level of adaptation, and that this can lead to excellent results with regard to specific problems which otherwise detract from the wellbeing of the patient and hamper the work of the medical team.

    Data of the DIAPHANE Dialyse-Informatique system of the Society of Nephrology have been collected by patients just on a home dialysis program after training in the hemodialysis Unit of the Hospital of Montreuil. 35 patients have been using the computerized records since January 1978. A critical analysis of the first year has been made and results obtained have been compared with those obtained during the same period in patients dialysed in the Hospital. Results show that home dialysis patients are well able to fill in the computerized medical record concerning the dialysis session follow-up, and that the quality of the recorded information is similar to that recorded in hospital by nurses. Nevertheless few simplifications of home dialysis data sheet are considered. Computerized treatment of data collected on home dialysis program should allow useful comparisons required to improve the quality of care and expansion of this dialysis method.

    This is a case report of a 43-year-old Caucasian male with end-stage renal disease being treated with hemodialysis and infective endocarditis in the aortic and tricuspid valves. The clinical presentation was dominated by neurologic impairment with cerebral embolism and hemorrhagic components. A thoracoabdominal computerized tomography scan revealed septic pulmonary embolus. The patient underwent empirical antibiotherapy with ceftriaxone, gentamicin and vancomycin, and the therapy was changed to flucloxacilin and gentamicin after the isolation of S. aureus in blood cultures. The multidisciplinary team determined that the patient should undergo valve replacement after the stabilization of the intracranial hemorrhage; however, on the 8th day of hospitalization, the patient entered cardiac arrest due to a massive septic pulmonary embolism and died. Despite the risk of aggravation of the hemorrhagic cerebral lesion, early surgical intervention should be considered in high-risk patients. PMID:26340160

    The purpose of this study was to explore Iranian nursing students' perspectives regarding caring for elderly patients. A qualitative design, based on the content analysis approach, was used to collect and analyze the perspectives of 25 senior nursing students who were providing care for elderly patients in the medical and surgical wards of two teaching hospitals in Tehran, Iran. After using purposeful sampling to select the participants, semistructured interviews were held in order to collect the data. During the data analysis, two main themes and six subthemes emerged. The first theme was "the barriers to caring for elderly patients", with the subthemes of "policies and rules of the organization", "a lack of educational preparation", and "an inappropriate physical environment", and the second theme was "the facilitators to caring for elderly patients", with the subthemes of "religion and cultural norms", "role modeling", and "previous exposure to elderly patients". This study informs international audiences of the factors that influence the quality of care of elderly patients so that strategies can be devised in order to prepare nursing students to meet the physical and psychological needs of elderly patients.

    Background and objectives Uncontrolled secondary hyperparathyroidism (sHPT) in patients with ESRD is a risk factor for calcific uremic arteriolopathy (CUA; calciphylaxis). Design, setting, participants, & measurements Adverse event reports collected during the Evaluation of Cinacalcet HCl Therapy to Lower Cardiovascular Events trial were used to determine the frequency of CUA in patients receiving hemodialysis who had moderate to severe sHPT, as well as the effects of cinacalcet versus placebo. CUA events were collected while patients were receiving the study drug. Results Among the 3861 trial patients who received at least one dose of the study drug, 18 patients randomly assigned to placebo and six assigned to cinacalcet developed CUA (unadjusted relative hazard, 0.31; 95% confidence interval [95% CI], 0.13 to 0.79; P=0.014). Corresponding cumulative event rates (95% CI) at year 4 were 0.011% (0.006% to 0.018%) and 0.005% (0.002% to 0.010%). By multivariable analysis, other factors associated with CUA included female sex, higher body mass index, higher diastolic BP, and history of dyslipidemia or parathyroidectomy. Median (10%, 90% percentile) plasma parathyroid hormone concentrations proximal to the report of CUA were 796 (225, 2093) pg/ml and 410 (71, 4957) pg/ml in patients randomly assigned to placebo and cinacalcet, respectively. Active use of vitamin K antagonists was recorded in 11 of 24 patients with CUA, nine randomly assigned to placebo, and two to cinacalcet, in contrast to 5%–7% at any one time point in patients in whom CUA was not reported. Conclusion Cinacalcet appeared to reduce the incidence of CUA in hemodialysis recipients who have moderate to severe sHPT. PMID:25887067

    Introduction The burden on the cardiovascular system is the main cause of mortality in chronic renal patients, and bone disease, which also may cause disability, is one of the most important complications in those patients. The aim of this study was to determine the link between cardiovascular and bone disease, which frequently occur together. Methods In this matched case-control study, 70 subjects were subjected for full laboratory assessment as well as estimation of parathyroid hormone (PTH) level, vitamin D level, complete echocardiography, and dual energy absorptiometry. Of the 70 patients, 50 were on regular hemodialysis, and there were 20 normal controls matched with the patients with respect to age and gender. Results There was a significant decrease in the mean value of serum vitamin D in the hemodialysis patients, i.e., their mean value was 20.47 ± 9.60 whereas the controls had a mean value of 37.15 ± 7.67. Thus, there was a highly-significant, negative correlation between vitamin D and left ventricular mass (LVM) in the patients. We found that there was a highly-significant increase in the mean PTH levels of the patients (820.22 ± 393.51), whereas it was 57.60 ± 13.72 for the controls. The statistical significance was less than 0.001, a highly-significant increase in the mean of the T score levels in the patients (−2.15 ± 2.56), whereas it was −0.47 ± 0.71 for the controls with a statistical significance of less than 0.001. There also was a highly-significant correlation between the T score and LVM. Conclusion A significant correlation was found between bone disease and the occurrence of a left ventricular mass. We recommend early strict correction of the serum levels of vitamin D, PTH, calcium, and phosphorus. PMID:27504162

    Patients receiving recombinant human erythropoietin (rHuEPO) therapy show wide variability in their responsiveness to the drug. Variables that affect rHuEPO dose requirements can be broadly divided into modificable and immutable characteristics. Most of the scientific research on rHuEPO hyporesponsiveness has focused on modificable variables (iron status, dialysis adequacy), while immutable variables such as gender, etiology of chronic renal failure (CRF) and age have been insufficiently explored. A cross sectional study was performed in order to evaluate if immutable patient characteristics determine rHuEPO dose requirements among 215 patients (52% males; mean age 66 +/- 14 years) on hemodialysis (HD) for more than twelve months. Data were collected at 10 hemodialysis units in Aragon. Patients were divided into three groups according to their gender, their cause of CRF (diabetic nephropathy, vascular nephropathy, tubulointerstitial nephropathy and primary glomerulonephritis) and their age (younger than 60 years, from 60 to 75 years, older than 75 years). Despite a similar dose of rHuEPO, women had lower mean hemoglobin (11.1 +/- 1.5 versus 11.6 +/- 1.7 g/dl; p = 0.0258) than men. The greater hemoglobin in men than women may be attributed to greater serum albumin in men (3.5 +/- 0.3 versus 3.7 +/- 0.3 mg/dl; p = 0.0001). Requirements of rHuEPO were higher in the patients with etiology of primary glomerulonephritis compared with those with the other etiologies, even those with diabetic nephropathy (p = 0.0374). The rHuE-PO doses required to obtain similar hemoglobin levels were higher in patients younger than 60 years (p = 0.0249). We conclude that women, patients with primary glomerulonephritis as cause of CRF, and patients younger than 60 years showed the highest requirements of rHuEPO doses. PMID:16392304

    Background and objectives Whether improvements in arterial compliance with BP lowering are because of BP reduction alone or if pleiotropic effects of antihypertensive agents contribute remains unclear. It was hypothesized that, among patients on hemodialysis, compared with a β-blocker (atenolol), a lisinopril-based therapy will better reduce arterial stiffness. Design, setting, participants, & measurements Among 200 participants of the Hypertension in Hemodialysis Patients Treated with Atenolol or Lisinopril Trial, 179 patients with valid assessment of aortic pulse wave velocity at baseline (89 patients randomly assigned to open-label lisinopril and 90 patients randomly assigned to atenolol three times a week after dialysis) were included in the secondary analysis. Among them, 109 patients had a valid pulse wave velocity measurement at 6 months. Monthly measured home BP was targeted to <140/90 mmHg by addition of antihypertensive drugs and dry weight adjustment. The difference between drugs in percentage change of aortic pulse wave velocity from baseline to 6 months was analyzed. Results Contrary to the hypothesis, atenolol-based treatment induced greater reduction in aortic pulse wave velocity relative to lisinopril (between drug difference, 14.8%; 95% confidence interval, 1.5% to 28.5%; P=0.03). Reduction in 44-hour ambulatory systolic and diastolic BP was no different between groups (median [25th, 75th percentile]; atenolol: −21.5 [−37.7, −7.6] versus lisinopril: −15.8 [−28.8, −1.5] mmHg; P=0.27 for systolic BP; −14.1 [−22.6, −5.3] versus −10.9 [−18.4, −0.9] mmHg, respectively; P=0.30 for diastolic BP). Between-drug difference in change of aortic pulse wave velocity persisted after adjustments for age, sex, race, other cardiovascular risk factors, and baseline ambulatory systolic BP but disappeared after adjustment for change in ambulatory systolic BP (11.8%; 95% confidence interval, −2.3% to 25.9%; P=0.10).

    Telomere shortening to a critical limit is associated with replicative senescence. This process is prevented by the enzyme telomerase. Oxidative stress and chronic inflammation are factors accelerating telomere loss. Chronic hemodialysis, typically accompanied by oxidative stress and inflammation, may be also associated with replicative senescence. To test this hypothesis, we determined telomere length and telomerase activity in peripheral blood mononuclear cells (PBMCs) in a cross-sectional study. Hemodialysis patients at the University Hospital Larissa and healthy controls were studied. Telomere length was determined by the TeloTAGGG Telomere Length Assay and telomerase activity by Telomerase PCR-ELISA (Roche Diagnostics GmbH, Mannheim, Germany). We enrolled 43 hemodialysis patients (17 females; age 65.0 ± 12.7 years) and 23 controls (six females; age 62.1 ± 15.7 years). Between the two groups, there was no difference in telomere length (6.95 ± 3.25 vs. 7.31 ± 1.96 kb; P = 0.244) or in telomerase activity (1.82 ± 2.91 vs. 2.71 ± 3.0; P = 0.085). Telomere length correlated inversely with vintage of hemodialysis (r = -0.332, P = 0.030). In hemodialysis patients, positive telomerase activity correlated with telomere length (r = 0.443, P = 0.030). Only age, and neither telomere length nor telomerase activity, was an independent survival predictor (hazard ratio 1.116, 95% confidence interval 1.009-1.234, P = 0.033). In this study, telomere length and telomerase activity in PBMCs are not altered in hemodialysis patients compared with healthy controls. Long duration of hemodialysis treatment is associated with telomere shortening and positive telomerase activity with an increased telomere length in PBMCs of hemodialysis patients. The underlying mechanism and clinical implications of our findings require further investigation.

    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.

    Providing health care and good hospital organization are always based on a well-educated and competent nurse. Nurses can significantly affect the result of overall treatment, which has a professional and financial effect. Nursing Informatics is a specialty that integrates nursing, computer and information science applied to nursing management as well as transfer of data, information and knowledge in nursing practice. This facilitates nurses' integration in supporting decision-making and implementation of health care. Informatics emphasizes overall nursing practice and nurses should have basic computer skills. In this article, we show how the use of simple tables, designed by using Microsoft Office programs (Word and Excel), has been employed for over a decade in facilitating the organization of daily work, monitoring of patients and their prescribed therapy. A trained nurse-manager will be able to evaluate patient care and to organize health care administration using all human and technical resources. The vision of the national health care system is still not achievable due to the lack of infrastructure. Nurses and computer documentation of patients with chronic kidney disease can significantly improve the quality of patient care and treatment. PMID:24979896

    This is a case presentation and discussion of a dialysis patient who presented to the surgical service with abdominal pain, hypotension, and tachycardia and in extremis who was found to have a contained retroperitoneal hematoma after rupture of his left kidney. Six months after an uneventful nephrectomy and postoperative recovery he again presented with hypotension and anemia and was found to have a contralateral retroperitoneal hematoma consistent with renal hemorrhage. After unsuccessful angioembolization, the patient underwent a right nephrectomy and recovered without sequelae. Bilateral spontaneous renal rupture is a rare event documented by only a few anecdotal reports in the literature and usually associated with acquired cystic kidney disease. Rupture of renal cysts is relatively common in renal cystic disease but usually presents as asymptomatic hematuria or flank pain. Trauma is the most common cause of renal rupture, but other causes of spontaneous renal rupture are rare and include polyarteritis nodosa and urothelial carcinoma. The diagnosis of acute abdominal pain in the dialysis patient is a challenging differential. While a rare complication the diagnosis of spontaneous renal rupture should not be excluded in a patient presenting with abdominal pain, hypotension, and anemia.

    Rotator cuff tears (RCT) are a common clinical problem in the geriatric population, and debate exists over how to best provide pain relief and restore shoulder function. Treatment options can be broadly divided into nonsurgical and surgical, with the majority of patients initially placed on a trial of conservative therapy. For those with irreparable RCT, low functional demand, or interest in nonoperative management, there are a number of nonsurgical treatments to consider, including rehabilitation and injections of corticosteroids, hyaluronate, and platelet-rich plasma. Surgical treatment is increasingly common, as geriatric patients remain active with high functional demands. Studies in elderly populations have demonstrated satisfactory healing and clinical results following surgical repair. Predictors of poor outcome after repair are large tear size as well as higher stages of fatty infiltration. Decompression is a less invasive surgical option that has been shown to provide short-term pain relief, though the lasting effects may deteriorate over time. A number of factors must be weighed when considering which patients are likely to benefit from surgical intervention. PMID:26328240

    Background 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. Study design Systematic review with meta-analysis. Population NHD patients. Search strategy 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. Intervention Transition from CHD to NHD. Outcomes Albumin, normalized protein catabolic rate (nPCR), dry body weight (DBW), body mass index (BMI), phase angle, protein intake, and energy intake. Results 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

    Malnutrition is very common in hemodialysis patients and is predisposed by many factors. Malnutrition is associated with increased morbidity and mortality. Total of 26 patients (16 males and 10 females) who were under hemodialysis in our center were included in the study. With the help of Malnutrition Score (MS) developed by Kalanter-Zadeh, nutritional status of the patients was assessed. Patients also underwent different anthropometric measurements such as Body Mass Index (BMI), Triceps skin fold thickness (TSF), Mid Arm Circumlference (MAC) and Mid Arm Muscle Circumference (MAMC) and laboratory investigations. Mean age of the study population was 42.58 +/- 16.32 years (range 19 to 74 years). Females were older than males. MS of the study population was 15.82 +/- 3.76 (range 9-24). Female patients were having higher MS than males (16.5 +/- 4.11 vs. 15.06 +/- 3.55). Based on MS, 22 patients (84.6%) had mild to moderate malnutrition, 2 (7.7%) patients were having severe malnutrition and remaining 2 (7.7%) had normal nutrition score. Females were having lower BMI, MAC and MAMC but higher value of TSF. Significant negative correlation was present between MS and weight, BMI, MAC and MAMC. Calculated Urea Reduction Ratio (URR) of study population was 57.27 +/- 10.89. URR was higher in females than in males (61.77 +/- 12.74 vs. 54.45 +/- 8.85). Only 23.0% of the study population had URR of >65.0%. Protein Catabolic Rate (nPCR) in our study was 0.77 +/- 0.28 g/kg/day. Malnutrition is very common in our center which is >90% when MS was considered. In our study it negatively correlated with weight, BMI, MAC and MAMC. Dialysis inadequacy was present in around 75.0% of our study population.

    Defibrotide pharmacokinetics were studied in 6 voluntary healthy subjects and in 10 uremic patients undergoing dialysis during which (instead of heparin) defibrotide was administered to prevent fibrino-formation in the circuit. Blood concentrations of the drug were assessed (expressed with reference to the residual glycidic deoxyribose) during a standard dialysis using defibrotide, 3.5, 15, 30, 45, 60 and 90 minutes after the defibrotide bolus (200 mg) had been injected into the arterial channel. The half-lives of the alpha and beta plasmatic phases were found to be equal at 3.79 and 41.4 min in dialysed subjects and at 1.13 and 16.54 in healthy volunteers. These results indicate that in uremic patients undergoing dialysis at intervals using defibrotide, a longer time is required to eliminate the drug from the circulation. This variation does not however appear to be significant in terms of the therapeutic use of the drug during dialysis.

    The incidence of superior vena cava (SVC) obstruction associated with non-malignant diseases is on the rise, and a large percentage of these patients are on hemodialysis (HD). The objective was to characterize the presentation, symptoms and outcomes of HD patients with SVC obstruction identified on computerized tomography (CT) compared to patients with other etiologies such as neoplasm. A search was performed through the PACS system using key words to identify patients with SVC obstruction. The CT scans and charts were reviewed for degree of obstruction, signs, symptoms and outcomes. Thirty-six patients were included in the study. Thirteen were on HD and of these, five had symptoms associated with SVC obstruction and one had concordant findings on physical exam. In comparison, thirteen patients with a chest neoplasm had symptoms and four had concordant findings on physical exam. On follow up, 31% of the HD patients died and of these 60% were symptomatic and died within 2 years. 29% of lung cancer patients died within 16 months. The majority of the HD patients had complete SVC obstruction (85%) as opposed to those with a chest neoplasm who mostly had partial SVC occlusion (67%). In conclusion, patients on HD with SVC obstruction are less often symptomatic than those with a neoplasm. However, these HD patients had a death rate similar to the patients with cancer. This risk seems to increase in those who are symptomatic. Diagnosis of SVC obstruction by CT in HD patients may help identify those with less favorable prognosis.
