    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 Frequent Hemodialysis Network Daily Trial randomized 245 patients to receive six (frequent) or three (conventional) in-center hemodialysis sessions per week for 12 months. As reported previously, frequent in-center hemodialysis yielded favorable effects on the coprimary composite outcomes of death or change in left ventricular mass and death or change in self-reported physical health. Here, we determined the long-term effects of the 12-month frequent in-center hemodialysis intervention. We determined the vital status of patients over a median of 3.6 years (10%-90% range, 1.5-5.3 years) after randomization. Using an intention to treat analysis, we compared the mortality hazard in randomized groups. In a subset of patients from both groups, we reassessed left ventricular mass and self-reported physical health a year or more after completion of the intervention; 20 of 125 patients (16%) randomized to frequent hemodialysis died during the combined trial and post-trial observation periods in contrast to 34 of 120 patients (28%) randomized to conventional hemodialysis. The relative mortality hazard for frequent versus conventional hemodialysis was 0.54 (95% confidence interval, 0.31 to 0.93); with censoring of time after kidney transplantation, the relative hazard was 0.56 (95% confidence interval, 0.32 to 0.99). Bayesian analysis suggested a relatively high probability of clinically significant benefit and a very low probability of harm with frequent hemodialysis. In conclusion, a 12-month frequent in-center hemodialysis intervention significantly reduced long-term mortality, suggesting that frequent hemodialysis may benefit selected patients with ESRD.

    Objective The purpose of the BalanceWise-hemodialysis study is to determine the efficacy of a dietary intervention to reduce dietary sodium intake in patients receiving maintenance, in-center hemodialysis (HD). Personal digital assistant (PDA)-based dietary self-monitoring is paired with behavioral counseling. The purpose of this report is to present a case study of one participant’s progression through the intervention. Methods The PDA was individually programmed with the nutritional requirements of the participant. With 25 minutes of personalized instruction, the participant was able to enter his meals into the PDA using BalanceLog® software. Nutritional counseling was provided based on dietary sodium intake reports generated by BalanceLog®. Results : At initiation of the study the participant required 4 HD treatments per week. The participant entered 342 meals over 16 weeks (≥3 meals per day). BalanceLog® revealed that the participant consumed restaurant/fast food on a regular basis, and consumed significant amounts of corned beef as well as canned foods high in sodium. The study dietitian worked with the participant and his wife to identify food alternatives lower in sodium. Baseline sodium consumption was 4,692 mg, and decreased at a rate of 192 mg/week on average. After 11 weeks of intervention, interdialytic weight gains were reduced sufficiently to permit the participant to reduce HD treatments from 4 to 3 per week. Because of a low serum albumin at baseline (2.9 g/dL) the study dietitian encouraged the participant to increase his intake of high quality protein. Serum albumin level at 16 weeks was unchanged (2.9 g/dL). Because of intense pruritis and a high baseline serum phosphorus (6.5 mg/dL) BalanceLog® electronic logs were reviewed to identify sources of dietary phosphorus and counsel the participant regarding food alternatives. At 16 weeks the participant’s serum phosphorus fell to 5.5 mg/dL. Conclusions Self-monitoring rates were excellent

    Despite technological advances in renal replacement therapy, the preservation of health and quality of life for individuals on dialysis still remains a challenge. The high morbidity and mortality in dialysis warrant further research and insight into the clinical domains of the technique and practice of this therapy. In the last 20 years, the focus of development in the field of hemodialysis (HD) has centered around adequate removal of urea and other associated toxins. High-dose HD offers an opportunity to improve mortality, morbidity, and quality of life of patients with end-stage kidney disease. However, the uptake of this modality is low, and the risk associated with the therapy is not fully understood. Recent studies have highlighted the evidence base and improved our understanding of this technique of dialysis. This article provides a review of high-dose and home HD, its clinical impact on patient outcome, and the controversies that exist. PMID:27462173

    Despite superior outcomes and lower associated costs, relatively few patients with end-stage renal disease undergo self-care or home hemodialysis. Few studies have examined patient- and physician-specific barriers to self-care and home hemodialysis in the modern era. The degree to which innovative technology might facilitate the adoption of these modalities is unknown. We surveyed 250 patients receiving in-center hemodialysis and 51 board-certified nephrologists to identify key barriers to adoption of self-care and home hemodialysis. Overall, 172 (69%) patients reported that they were "likely" or "very likely" to consider self-care hemodialysis if they were properly trained on a new hemodialysis system designed for self-care or home use. Nephrologists believed that patients were capable of performing many dialysis-relevant tasks, including: weighing themselves (98%), wiping down the chair and machine (84%), clearing alarms during treatment (53%), taking vital signs (46%), and cannulating vascular access (41%), but thought that patients would be willing to do the same in only 69%, 34%, 31%, 29%, and 16%, respectively. Reasons that nephrologists believe patients are hesitant to pursue self-care or home hemodialysis do not correspond in parallel or by priority to reasons reported by patients. Self-care and home hemodialysis offer several advantages to patients and dialysis providers. Overcoming real and perceived barriers with new technology, education and coordinated care will be required for these modalities to gain traction in the coming years. PMID:26415746

    Patient experience surveys provide a critical and unique perspective on the quality of patient-centered healthcare delivery. These surveys provide a mechanism to systematically express patients' voice on topics valued by patients to make decisions about choices in care. They also provide an assessment to healthcare organizations about their service that cannot be obtained from any other source. Regulatory agencies have mandated the assessment of patients' experience as part of healthcare value based purchasing programs and weighted the results to account for up to 30% of the total scoring. This is a testimony to the accepted importance of this metric as a fundamental assessment of quality. After more than a decade of rigorous research, there is a significant body of growing evidence supporting specifically the validity and use of the Consumer Assessment of Healthcare Providers and Systems (CAHPS) surveys, including a version specific to in-center hemodialysis (ICH CAHPS). This review will focus on the ICH CAHPS survey including a review of its development, content, administration, and also a discussion of common criticisms. Although it is suggested that the survey assesses activities and experiences that are not modifiable by the healthcare organization (or the dialysis facility in our case) emerging evidence suggests otherwise. Dialysis providers have an exclusive opportunity to lead the advancement of understanding the implications and serviceability of the evaluation of the patient experience in health care.

    A 30-year-old woman with stage V chronic kidney disease presented at 7 weeks gestation. She had no uremic symptoms; however, blood urea nitrogen (BUN) was 33.6 mg/dL. Because of the well-established negative relationship between BUN and fetal outcomes, dialysis was initiated with a nocturnal home hemodialysis (NHD)-like prescription performed in-center for logistical reasons. She received 36 hours per week of dialysis. Following the initiation of renal replacement therapy, the predialysis BUN was within the normal physiologic range. The patient had an uncomplicated pregnancy with delivery of a healthy 3000 g infant at 39 weeks gestation. This case adds to the growing literature that supports more intensive dialysis in the pregnant women than was previously recommended. This dose of dialysis should be offered to women in an in-center setting if nocturnal home hemodialysis is not available or feasible. PMID:22093603

    The use of cooled dialysate temperatures first came about in the early 1980s as a way to curb the incidence of intradialytic hypotension (IDH). IDH was then, and it remains today, the most common complication affecting chronic hemodialysis patients. It decreases quality of life on dialysis and is an independent risk factor for mortality. Cooling dialysate was first employed as a technique to incite peripheral vasoconstriction on dialysis and in turn reduce the incidence of intradialytic hypotension. Although it has become a common practice amongst in-center hemodialysis units, cooled dialysate results in up to 70% of patients feeling cold while on dialysis and some even experience shivering. Over the years, various studies have been performed to evaluate the safety and efficacy of cooled dialysate in comparison to a standard, more thermoneutral dialysate temperature of 37 °C. Although these studies are limited by small sample size, they are promising in many aspects. They demonstrated that cooled dialysis is safe and equally efficacious as thermoneutral dialysis. Although patients report feeling cold on dialysis, they also report increased energy and an improvement in their overall health following cooled dialysis. They established that cooling dialysate temperatures improves hemodynamic tolerability during and after hemodialysis, even in patients prone to IDH, and does so without adversely affecting dialysis adequacy. Cooled dialysis also reduces the incidence of IDH and has a protective effect over major organs including the heart and brain. Finally, it is an inexpensive measure that decreases economic burden by reducing necessary nursing intervention for issues that arise on hemodialysis such as IDH. Before cooled dialysate becomes standard of care for patients on chronic hemodialysis, larger studies with longer follow-up periods will need to take place to confirm the encouraging outcomes mentioned here.

    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. PMID:26875228

    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

    Favorable clinical outcomes related to morbidity, mortality, patient well-being, laboratory biomarkers, and medication use have been reported with in-center nocturnal hemodialysis (INHD); nevertheless, it is not entirely clear how much patient selection or physiologic mechanisms related to better fluid management and phosphorus (and calcium) metabolism may explain these outcomes. There are indications that INHD may be a preferred treatment option in specific cases, such as in patients with high interdialytic weight gain, poor tolerance to high ultrafiltration rate, hyperphosphatemia, or for those patients who work or go to school during the day. In the era of the new prospective payment system where quality standards become intertwined with reimbursement, an INHD program may be a useful method to help attain quality goals in facilities that have patients with unfavorable case-mix. The experience of the past decade has shown INHD to be safe and well tolerated by patients. The growth of INHD therapy is a testament to sustainability and feasibility of this treatment option. Prospective clinical trials are needed in this area. If the promise of INHD is fulfilled, it may also prove to be a valuable option for potential success of Accountable Care Organizations where providers need to assume responsibility for more patient-centered care and improvement in clinical outcomes. In summary, based on the current experience, INHD is a viable and valuable option as an additional, alternative hemodialysis (HD) regimen to conventional HD. PMID:22106828

    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.

    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

    Fifteen male hemodialysis patients developed 21 episodes of S. aureus bacteremia. Infections involving vascular access were responsible for 65% of initial bacteremias. The arteriovenous fistula was the most prevalent type of access used, and thus was responsible for the majority of these illnesses. Phage typing indicated that recurrent episodes were due to reinfection rather than relapse. Complications included endocarditis, osteomyelitis, septic embolism, and pericarditis. One patient died of infectious complications. It is recommended that hemodialysis patients developing bacteremia due to S. aureus receive at least 6 weeks of beta lactamase-resistant antimicrobial therapy. PMID:608860

    The quality of life is considerably impaired in patients on regular hemodialysis has been changed. It is difficult to determine it because there are no general definitions or measuring instruments. There are objective and subjective components of the quality of life, one among them being occupational ability. During the progression of chronic renal disease (CRD) to terminal renal failure (TRF) physical activity of the patients becomes poorer. In this stage, their physical activity is by 40-60% below the value expected for the same healthy age cohort. The intention of this analysis was to determine occupational ability in patients on regular hemodialysis. The analysis included 161 patients on hemodialysis, 78 (48.5%) female and 83 (51.5%) male, mean age 61.2 +/- 13.1 years, and mean time on hemodialysis was 54 +/- 71.9 months. All patients filled-out a self-administered questionnaire on schooling and occupational ability. The cause of TRF was glomerulonephritis in 45 (26.8%), diabetes mellitus in 42 (26.3%), nephrosclerosis in 26 (16.1%), and pyelonephritis in 12 (7.4%) patients. Age distribution was as follows: 0-19 years 1 patient, 20-44 years 14 (8.7%); 45-64 years 64 (39.8%) and 65 years 82 (50.9%) patients. Educational structure: elementary school 65 (40.4%), secondary school 79 (49.1%), college 10 (6.2%), and university 6 (3.7%) patients. Occupational structure: retired 123 (76.4%), housekeeper 20 (12.4%), never employed 4 (2.5%), employed 10 (6.2%), unemployed 2 (1.2%), 1 child and 1 student. Among employed patients there were 7 men and 3 women. Their educational level was as follow: elementary school 1 patient, secondary school 8 patients, college 1 patient. At the beginning of hemodialysis their occupational status was: full-time employment 30 (18.6%) patients, part-time employment 1 patient, longer time on sick-leave payment (3.1%), retired 95 (59%), pupils and students 3, unemployed 2, and 1 child did not attended school.

    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

    Despite the continuous improvement of dialysis technology and pharmacological treatment, mortality rates for dialysis patients are still high. A 2-year prospective study was conducted at a tertiary care hospital to determine the factors influencing survival among patients on maintenance hemodialysis. 96 patients with end-stage renal disease surviving more than 3 months on hemodialysis (8-12 h/week) were studied. Follow-up was censored at the time of death or at the end of 2-year study period, whichever occurred first. Of the 96 patients studied (mean age 49.74 ± 14.55 years, 75% male and 44.7% diabetics), 19 died with an estimated mortality rate of 19.8%. On an age-adjusted multivariate analysis, female gender and hypokalemia independently predicted mortality. In Cox analyses, patient survival was associated with delivered dialysis dose (single pool Kt/V, hazard ratio [HR] =0.01, P = 0.016), frequency of hemodialysis (HR = 3.81, P = 0.05) and serum albumin (HR = 0.24, P = 0.005). There was no significant difference between diabetes and non-diabetes in relation to death (Relative Risk = 1.109; 95% CI = 0.49-2.48, P = 0.803). This study revealed that mortality among hemodialysis patients remained high, mostly due to sepsis and ischemic heart disease. Patient survival was better with higher dialysis dose, increased frequency of dialysis and adequate serum albumin level. Efforts at minimizing infectious complications, preventing cardiovascular events and improving nutrition should increase survival among hemodialysis patients. PMID:25097332

In Cox analyses, patient survival was associated with delivered dialysis dose (single pool Kt/V, hazard ratio [HR] =0.01, P = 0.016), frequency of hemodialysis (HR = 3.81, P = 0.05) and serum albumin (HR = 0.24, P = 0.005). There was no significant difference between diabetes and non-diabetes in relation to death (Relative Risk = 1.109; 95% CI = 0.49-2.48, P = 0.803). This study revealed that mortality among hemodialysis patients remained high, mostly due to sepsis and ischemic heart disease. Patient survival was better with higher dialysis dose, increased frequency of dialysis and adequate serum albumin level. Efforts at minimizing infectious complications, preventing cardiovascular events and improving nutrition should increase survival among hemodialysis patients. PMID:25097332

    Background/Aims In 2004, the Centers for Medicare & Medicaid Services tied reimbursement for outpatient hemodialysis services to number of times per month providers see their dialysis patients, resulting in increased provider-patient visit frequency. Greater provider-patient visit frequency is associated with lower hospitalization risk for hemodialysis patients. Determinants of visit frequency are uncertain. We aimed to identify patient, provider, and dialysis facility characteristics associated with provider visit frequency. Methods This retrospective cohort study used United States Renal Data System (USRDS) data for point-prevalent patients receiving in-center hemodialysis on January 1, 2006 (n = 144,860). Patient characteristics were defined January 1-June 30, 2006, and provider-patient visit frequency (< 4 vs. ≥ 4 visits/month) July 1-December 31, 2006. Patient characteristics were obtained from the USRDS. Provider data were obtained from the American Medical Association Physician Master File. We determined longitudinal associations between patient, provider, and facility characteristics and provider-patient visit frequency using logistic regression. Results Patient characteristics independently associated with greater provider-patient visit frequency included older age, African American race, longer dialysis duration, higher comorbidity score, Medicaid eligibility, urban residence, better compliance with dialysis, and more hospital days during run-in. Provider characteristics associated with greater provider-patient visit frequency included more years in practice, graduation from a foreign medical school, shorter distance between provider office and dialysis unit, and caring for more dialysis patients; facility characteristics included free-standing, independent status. Conclusion After the Medicare reimbursement policy change, several patient, provider, and facility characteristics were independently associated with greater dialysis provider-patient visit

    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. This study investigated the epidemiology of torus palatinus (TP) and torus mandibularis (TM) in hemodialysis patients and analyzed the influences of hyperparathyroidism on the formation of oral tori. Method. During 2013, 119 hemodialysis patients were recruited for dental examinations for this study. Results. The prevalence of oral tori in our sample group was high at 33.6% (40 of 119). The most common location of tori was TP (70.0%), followed by TM (20.0%), and then both TP and TM (10.0%). Of the 40 tori cases, most (67.5%) were <2 cm in size; moreover, the majority (52.5%) were flat in shape. In symmetry, most (70.0%) occurred in the midline, followed by bilateral sides (20.0%). Notably, the levels of intact parathyroid hormone did not differ in patients with or without tori (P = 0.611). Furthermore, patients with tori did not differ from patients without tori in inflammatory variables such as log high-sensitivity C-reactive protein (P = 1.000) or nutritional variables such as albumin (P = 0.247). Finally, there were no differences between patients with and without tori in adequacy of dialysis (P = 0.577). Conclusions. Neither hyperparathyroidism nor inflammation malnutrition syndrome was found to contribute to the formation of oral tori in chronic hemodialysis patients. Further studies are warranted.

    This study examined variables that may influence the employment potential of hemodialysis patients. The study group consisted of currently employed (n = 20) and currently unemployed (n = 20) hemodialysis patients. All subjects had been employed before starting dialysis and were currently judged physically able to work by their physicians. No significant differences were found in job satisfaction or job importance before starting dialysis. The groups did not differ on biophysiological status or perception of health. However, a greater number of the unemployed had held jobs requiring heavier physical labor and reported that uremic symptoms prevented them from working. They also encountered more job discrimination due to illness and had a greater loss of career and life goals. No significant differences were found between the two groups in life satisfaction or dependence. In both groups the more independent subjects reported greater satisfaction with life. PMID:3850487

    Little information is available on the impact of hemodialysis on cerebral water homeostasis and its distribution in chronic kidney disease. We used a neuropsychological test battery, structural magnetic resonance imaging (MRI) and a novel technique for quantitative measurement of localized water content using 3T MRI to investigate ten hemodialysis patients (HD) on a dialysis-free day and after hemodialysis (2.4±2.2 hours), and a matched healthy control group with the same time interval. Neuropsychological testing revealed mainly attentional and executive cognitive dysfunction in HD. Voxel-based-morphometry showed only marginal alterations in the right inferior medial temporal lobe white matter in HD compared to controls. Marked increases in global brain water content were found in the white matter, specifically in parietal areas, in HD patients compared to controls. Although the global water content in the gray matter did not differ between the two groups, regional increases of brain water content in particular in parieto-temporal gray matter areas were observed in HD patients. No relevant brain hydration changes were revealed before and after hemodialysis. Whereas longer duration of dialysis vintage was associated with increased water content in parieto-temporal-occipital regions, lower intradialytic weight changes were negatively correlated with brain water content in these areas in HD patients. Worse cognitive performance on an attention task correlated with increased hydration in frontal white matter. In conclusion, long-term HD is associated with altered brain tissue water homeostasis mainly in parietal white matter regions, whereas the attentional domain in the cognitive dysfunction profile in HD could be linked to increased frontal white matter water content.

    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.

    A review of the experience with 66 patients on chronic hemodialysis who underwent 67 major surgical procedures is presented. There were 58 general surgical procedures, and nine major cardiovascular procedures including four emergency cardiac valve replacements. The preoperative, intraoperative and postoperative management of these patients is discussed as well as the morbidity and mortality encountered. It is concluded that patients on well-managed chronic dialysis will tolerate minor and major surgery well and renal failure should no longer be regarded as a relative contraindication for appropriate elective or emergency surgery.

    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.

    Restless legs syndrome (RLS) is a neurological disorder characterized by uncomfortable sensation of paresthesia in legs that subsequently causes involuntary and continuous movement of the lower limbs, especially at rest. Its prevalence in hemodialysis is more than that in the general population. Different risk factors have been suggested for RLS. We studied the prevalence and risk factors of RLS in 137 hemodialysis patients followed up at our center. The patients completed at least three months on dialysis and fulfilled four criteria for the diagnosis of RLS. We compared the patients with and without RLS, and the odds ratios (ORs) were estimated by the logistic regression models. The prevalence of RLS was 36.5% in the study patients. Among the variables, diabetes was the only predicting factor for the development of RLS. The diabetic patients may be afflicted with RLS 2.25 times more than the non-diabetics. Women developed severe RLS 5.23 times more than men. Neurodegeneration, decrease in dopamine level, higher total oxidant status, and neuropathy in diabetic patients may explain the RLS symptoms.

    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.

    There is substantial variability at international, national, and regional levels in how effective dialysis providers are in the implementation of well-accepted interventions to deliver better health outcomes at reduced costs to payers. The growing number of dialysis patients within a finite pool of resources has led to searches for more efficient methods to provide patient care without compromising or diminishing quality. We review here some contemporary concepts surrounding quality improvement and operations research that may provide clinician administrators to both improve efficiency and quality in facility based hemodialysis units. The creation of balanced scorecards, utilization of process mapping techniques, and the application of LEAN principles may readily improve how hemodialysis care is delivered in an environment of increasing patient volumes and reduced operating resources.

    Oxycodone and oxycodone-containing analgesics are often used for the relief of pain. In the presence of renal dysfunction, the half-life of oxycodone and metabolites can be prolonged. We describe the case of a 41-year-old chronic hemodialysis patient who received multiple doses of oxycodone/acetaminophen resulting in accumulation of the medication and consequent lethargy, hypotension and respiratory depression. These adverse effects were reversed with multiple bolus doses of naloxone, followed by a continuous infusion administered for 45 hours. Utilizing the Naranjo probability scale, the patient had a "probable" adverse drug reaction to the oxycodone. Oxycodone should be used with caution in patients with chronic renal failure.

    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.

    2011-01-01

    Background Over 290,000 patients are undergoing hemodialysis (HD) in Japan. With old age, the odds of undergoing HD treatment sharply increase, as does the prevalence of cognitive impairment. The aim of the present work was to assess cognitive impairment in HD patients and its relation to clinical characteristics. Methods Using a cross-sectional design, we administered the Mini-Mental State Examination (MMSE) to 154 HD outpatients and 852 participants from the Iwaki Health Promotion Project 2010, representing the general population. Results The prevalence of cognitive impairment based on the MMSE was 18.8% in HD patients. HD patients showed a higher prevalence of cognitive impairment in older groups (50 years and older). In a logistic regression model with age, gender and amount of education as covariates, undergoing HD was a significant independent factor (OR = 2.28, 95% CI 1.33 to 3.94) associated with a lower MMSE score. Among HD patients, we found that level of education was associated with MMSE score. Conclusions There is a high prevalence of cognitive impairment among HD patients that has adverse implications for hospitalization and shortens their life expectancy. HD treatment was an independent risk factor for cognitive impairment. Clinicians should carefully monitor and treat cognitive impairment in HD patients. Further studies are required to determine the reasons for cognitive impairment in HD patients. PMID:21867512

    Objectives Plasma levels of copeptin, a surrogate marker for the vasoconstrictor hormone arginine vasopressin (AVP), are increased in hemodialysis patients. Presently, it is unknown what drives copeptin levels in hemodialysis patients. We investigated whether the established physiological stimuli for copeptin release, i.e. plasma osmolality, blood volume and mean arterial pressure (MAP), are operational in hemodialysis patients. Methods One hundred and eight prevalent, stable hemodialysis patients on a thrice-weekly dialysis schedule were studied during hemodialysis with constant ultrafiltration rate and dialysate conductivity in this observational study. Plasma levels of copeptin, sodium, MAP, and blood volume were measured before, during and after hemodialysis. Multivariate analysis was used to determine the association between copeptin (dependent variable) and the physiological stimuli plasma sodium, MAP, excess weight as well as NT-pro-BNP immediately prior to dialysis and between copeptin and changes of plasma sodium, MAP and blood volume with correction for age, sex and diabetes during dialysis treatment. Results Patients were 63±15.6 years old and 65% were male. Median dialysis vintage was 1.6 years (IQR 0.7–4.0). Twenty-three percent of the patients had diabetes and 82% had hypertension. Median predialysis copeptin levels were 141.5 pmol/L (IQR 91.0–244.8 pmol/L). Neither predialysis plasma sodium levels, nor NT-proBNP levels, nor MAP were associated with predialysis copeptin levels. During hemodialysis, copeptin levels rose significantly (p<0.01) to 163.0 pmol/L (96.0–296.0 pmol/L). Decreases in blood volume and MAP were associated with increases in copeptin levels during dialysis, whereas there was no significant association between the change in plasma sodium levels and the change in copeptin levels. Conclusions Plasma copeptin levels are elevated predialysis and increase further during hemodialysis. Volume stimuli, i.e. decreases in MAP and blood

    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

    Chronic hemodialysis (HD) patients are predisposed to several complications associated with pleural effusion. In addition, uremia can directly cause pleuritis. However, there are inadequate data about pathogenesis and natural course of uremic pleuritis. In this study, 76 chronic HD patients with pleural effusion admitted to the Respiratory Center of Masih Daneshvari Hospital, in Tehran, Iran between June 2005 and May 2011 were evaluated to figure out the etiology of their pleural disease. Among these patients, patients with uremic pleuritis were identified and studied. The rate of uremic pleuritis was 23.7%. Other frequent etiologies of pleural effusion were parapneumonic effusion (23.7%), cardiac failure (19.7%), tuberculosis (6.6%), volume overload, malignancy, and unknown. In patients with uremic pleuritis, dyspnea was the most common symptom, followed by cough, weight loss, anorexia, chest pain, and fever. Compared to patients with parapneumonic effusion, patients with uremic effusion had a significantly higher rate of dyspnea and lower rate of cough and fever. Pleural fluid analysis showed that these patients had a significantly lower pleural to serum lactic dehydrogenase ratio, total pleural leukocytes, and polymorphonuclear count compared to patients with parapneumonic effusion. Improvement was achieved in 94.1% of patients with uremic pleuritis by continuation of HD, chest tube insertion or pleural decortication; an outcome better than the previous reports. Despite the association with an exudative effusion, inflammatory pleural reactions in patients with uremic pleuritis may not be as severe as infection-induced effusions. Owing to the advancement in HD technology and other interventions, outcome of uremic pleuritis may be improved. PMID:22716271

    When kidney failure occurs, patients are at risk for fluid overload states, which can cause pulmonary edema, pleural effusions, and upper airway obstruction. Kidney disease is also associated with impaired respiratory function, as in central sleep apnea or chronic obstructive pulmonary disease. Hence, respiratory and renal diseases are frequently coexisting. Hypoxemia is the terminal pathway of a multitude of respiratory pathologies. The measurement of oxygen saturation (SO2) is a basic and commonly used tool in clinical practice. Both arterial oxygen saturation (SaO2) and central venous oxygen saturation (ScvO2) can be easily obtained in hemodialysis (HD) patients, SaO2 from an arteriovenous access and ScvO2 from a central catheter. Here, we give a brief overview of the anatomy and physiology of the respiratory system, and the different technologies that are currently available to measure oxygen status in dialysis patients. We then focus on literature regarding intradialytic SaO2 and ScvO2. Lastly, we present clinical vignettes of intradialytic drops in SaO2 and ScvO2 in association with different symptoms and clinical scenarios with an emphasis on the pathophysiology of these cases. Given the fact that in the general population hypoxemia is associated with adverse outcomes, including increased mortality, cardiac arrhythmias and cardiovascular events, we posit that intradialytic SO2 may serve as a potential marker to identify HD patients at increased risk for morbidity and mortality.

    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.

    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 and aims Cardiovascular (CV) disease is the leading cause of morbidity and mortality in hemodialysis (HD) patients. Kidney disease is associated with increased oxidative stress (OS), a nontraditional CV risk factor. Few studies evaluate the effect of OS markers on CV events (CVE) and survival in HD patients. The aim of this study is to examine potential determinants of OS markers and their predictive role on survival and CV morbidity and mortality in HD patients during a long-term follow-up (108 months). Methods We conducted an analytical cross-sectional prospective observational study, carried on a cohort of randomly selected HD patients. We registered in 44 HD patients baseline characteristics, OS markers, mortality and CVE over a period of 108 months and we used statistical analysis (descriptive, Kaplan-Meier, univariate and multivariate Cox model) for interpretation. Results Bound malondialdehyde (bMDA) was positively correlated with serum calcium, protein carbonyls (PC) were inversely correlated with diastolic blood pressure (DBP) and directly correlated with ferritin, NOx was directly correlated with ceruloplasmin) and serum albumin. Of the measured OS markers only bMDA was related to survival (HR=3.29 95% CI (1.28–8.44), p=0.01), and approached statistical significance in the effect on CV mortality (HR=2.85 95% CI (0.88–9.22), p=0.07). None of the measured OS markers was associated with CVE. Conclusions bMDA has a strong predictive value on survival in HD patients in a long-term follow-up (9 years). Its value is correlated with CV mortality but is not a predictor of CV events. Regular assessment of MDA in HD patients and the development of strategies aimed at reducing oxidative stress in these patients might be beneficial. PMID:27152077

    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.

    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

    Medication adherence was assessed in 89 patients on hemodialysis (HD) at the King Abdul Aziz Medical City using an Arabic version of the Morisky Medication Adherence Scale (MASS-8). The results of the study revealed that 31.46% and 40.45% of the participants showed low and medium adherence, respectively, while 28.09% showed high medication adherence. Accordingly, 71.91% of the patients visiting the dialysis unit were considered medication non-adherent. While being of older age (P = 0.012), being married (P = 0.012) increased the level of adherence, being of medium level of education (P = 0.024) decreased adherence levels. On the other hand, gender, presence of a care-giver, number of members in the household and employment status seems to have no effect on the level of medication adherence. These results call upon the practitioners in HD units to develop intervention programs that can increase the level of medication adherence. PMID:24969185

    We are reporting a cloxacillin-induced seizure in a patient with stage 5 chronic kidney disease requiring hemodialysis. To our knowledge, there are no published case reports of seizures induced by parenteral cloxacillin in hemodialysis patients. A young hemodialysis female was admitted to the hospital with decreased level of consciousness. Blood cultures revealed methicillin-sensitive Staphylococcus aureus where cloxacillin 2 g intravenously every 4 hours was initiated. Head computed tomography (CT) was not significant. After 14 hours of cloxacillin therapy (4 doses), the patient demonstrated tonic/clonic seizure activity, where phenytoin and lorazepam were initiated. The anti-seizure medications partially reduced seizure activity. Once the cloxacillin was discontinued, the seizures stopped. Two weeks later, all anti-seizure medications were stopped with no further seizure activity. Cloxacillin elimination in hemodialysis patients is similar to patients with normal kidney function. Although cloxacillin does not significantly cross the blood-brain barrier, the correlation between the start of seizures and cloxacillin initiation was confirmed by the negative CT and blood chemistry laboratory results. Moreover, seizure activity was terminated upon discontinuation of cloxacillin. Although further investigation for the cause of such seizures is warranted, clinicians should use caution when giving high doses of cloxacillin in hemodialysis patients. PMID:25582344

    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

    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

    Introduction: The restless leg syndrome (RLS) is a neurologic disorder suffering the hemodialysis patients. 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.

    AIM To compare the effect of cataract surgery in renal transplantation and hemodialysis patients. METHODS We evaluated 51 eyes of 31 renal transplantation patients, 41 eyes of 29 hemodialysis patients and 45 eyes of 32 normal control patients who received phacoemulsification and intraocular lens (IOL) implantation from January, 2000 to August, 2014 in the Beijing Friendship Hospital. Each individual underwent a blood routine and a kidney function examination. Routine ophthalmologic examination included best-corrected visual acuity (BCVA), a slit-lamp examination to detect cataract type, determination of intraocular pressure, a corneal endothelial count, and fundus examination. All patients received phacoemulsification and an IOL implantation. RESULTS For the types of cataract in the three groups, transplantation group was significantly different from normal control group (P=0.04), the most kind is posterior subcapsular cataract (PSC) in transplantation group 33 (64.7%), hemodialysis group had no significantly difference from normal control group (P=0.43), and the difference between transplantation group and hemodialysis group also had significantly difference (P=0.02). For postoperative BCVA in the three groups, transplantation group had significantly difference from normal control group (P=0.03), hemodialysis group was significantly different from normal control group (P=0.00), and the difference between transplantation group and hemodialysis group also had significantly difference (P=0.00). The multiple linear regression equation is Y=0.007 hemoglobin (Hb)-0.000233 serum creatinine (Cr), R2=0.898. Postoperative fundus examination showed that hemorrhage, exudation, and macular degeneration were greater in the hemodialysis group. CONCLUSION This study showed that the PSC was more in the renal transplantation patients. BCVA was better and fundus lesions were less frequent in the renal transplantation group than in the hemodialysis group after cataract surgery. The

    Introduction: Based on the statistics the population in Bosnia and Herzegovina is getting older. In 2013 the average life span for women was 73.6 years and 68.1 for men. The chronic hemodialysis program is mainly reserved for elderly patients with high mortality risk. The most common cause of hemodialysis mortality relates to cardiovascular diseases (60.2%), regardless of frequent innovations and improvement of hemodialysis procedures. The aim of the study: was to determine the mortality rate by age groups with comments on the presence of non-traditional predictors (anemia, hypoalbuminemia, CRP, vascular access and PTH) in dialysis patients in the follow-up period of 36 months. Methods: The study included all patients undergoing chronic hemodialysis treatment at the Clinic of Hemodialysis of the Clinical Center University of Sarajevo (CCUS). Results: Out of a total number of hemodialysis patients (n=232), the specific mortality rate in patients under 65 years of age was 16.8%, and 50.5% in patients over 65 years of age. According to the age groups the mortality rate in elderly patients is as follows: from 65 to 74 years (45.1%), from 75 to 84 years (55.0%), over ≥85 years (75.0%). The most frequent vascular access in patients under and above 65 is arteriovenous fistula (79.6% and 62.1 %), temporary hemodialysis catheter (11.7% and 43.8 %) and long-term hemodialysis catheter (8.8% and 4.2 %). In the age group under 65 years of age the temporary hemodialysis catheter is significantly and more frequently used in diseased patients in respect to survivors (34.8% vs. 7.0%) [χ2(2)=15.769, p=0.001]. Diseased patients from the age group over 65 had a significantly lower mean value of haemoglobin in blood (M=100.9±17.5 g/L) in respect to survivors (M=109.2±17.1)[t(93)=2.339; p=0.021], lower mean value of albumin in blood (Me=32.0; IQR=29.0 do 35.0) in respect to survivors (Me=34.0; IQR=32.0 to 38.0) [U=762.5; p=0.006], and higher mean value of CRP in blood (Me=19.3 mg

    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

    Background: Hemodialysis patients are exposed to different stressful factors and have to use coping strategies as supportive processes. The goal of the present study is to investigate coping styles of hemodialysis patients. Materials and Methods: This is a descriptive analytical study conducted on 96 patients referring to hemodialysis centers affiliated to Isfahan University of Medical Sciences in 2011. The data, collected by a questionnaire including two sections of demographic characteristics and patients’ coping with the disease, were analyzed by parametric and non- parametric statistical tests. Results: Patients used emotion focused coping strategies more (mean = 20.07, SD = 4.39) to adapt with the disease compared to problem focused coping strategies (mean = 14.65, SD = 5.08). There was a significant association in coping (P = 0.027) and emotion focused dimension (P = 0.008) in various ages, but there was no significant association in problem focused dimension (P = 0.134). Conclusion: Since most of the hemodialysis patients use emotion focused coping styles, it is suggested to consider educational programs on application of problem focused coping styles for these patients in order to decrease the pressures of the disease and treatment, and to promote their mental health, quality of life and efficiency.

    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

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

    Background: 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.

    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

    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

    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. PMID:23334394

    Venous anomalies are diagnostic and therapeutic challenges. Subclavian or superior vena cava stenosis can be developed and venous return can be achieved via cardiac veins and coronary sinus in patients with central venous catheter for long-term hemodialysis. These types of abnormalities are not extremely rare especially in patients with a history of central venous catheter placement. Detection of these anomalies and subclavian vein stenosis before the surgical creation of hemodialysis fistulae or tunneled central venous catheter placement may prevent unnecessary interventions in those patients. Multidetector computed tomography (MDCT) technique can give further information when compared with fluoroscopy or digital subtraction angiography in the management of these patients. This case report describes interesting aspects of central vein complications in hemodialysis patients. As a conclusion, there are limited data about thoracic venous return, and further prospective studies with large patient number are required. MDCT with 3D reconstruction is particularly useful for the accurate evaluation of venous patency, variations, and collateral circulation. Also it is an excellent tool for choosing and planning treatment. PMID:27056032

    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

    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

    Occult hepatitis C virus (HCV) infection (OCI) was reported in an apparently disease-free state in the absence of liver disease, anti-HCV and HCV-RNA in the serum. The existing data examining the clinical significance of OCI and its potential as a source of HCV infection among hemodialysis patients are very limited. We examined the presence of OCI among patients on maintenance hemodialysis at Minia Governorate, Egypt; an HCV endemic country. A total of 81 subjects with negative markers for HCV were enrolled. HCV-RNA was tested in PBMCs by real-time PCR. For the 81 subjects, the average dialysis duration was 32.7 ± 21.7 months and the average ALT level (±SD) was 26 ± 12 U/L while that of AST was 29 ± 16 U/L. Out of the 81 subjects, three (3.7%) were HCV-RNA positive in PBMCs in the absence of serum anti-HCV and HCV-RNA indicating OCI. The viral load of the OCI subjects ranged from 172 to 4150 IU/ml. History of liver disease was positive in one of the three positive patients. These results highlight the potential risk of HCV transmission from patients within hemodialysis units in Egypt. J. Med.

    Restless legs syndrome (RLS) is a common sleep disorder that can present secondary to medical conditions such as renal failure. This study aimed to evaluate RLS frequency and its related factors in chronic renal failure patients treated with hemodialysis. In a cross-sectional design, 163 patients with chronic renal failure were consecutively enrolled from hemodialysis center at Rasool-Akram hospital. Demographics, clinical and laboratory data were recorded. Patients were screened for presence and severity of RLS according to the four International Restless Legs Syndrome Group (IRLSSG) diagnostic criteria and severity scale. Patients with and without RLS were compared using SPSS statistical software (Version 16.0). Sixty-one patients (37.4 %) were diagnosed with RLS. Mean age in RLS group was significantly higher (65.2 ± 9.3 years) than RLS-negative group (59.0 ± 14.7 years; P = 0.004). Serum creatinine level was significantly higher in patients with RLS (7.6 ± 2.1 mg/dl vs. 6.7 ± 1.8 mg/dl; P = 0.009). Glomerular filtration rate in RLS patients was lower than other patients (9.2 ± 3.1 ccs/min vs. 11.6 ± 4.8 ccs/min; P = 0.0001). Patients with RLS had shorter sleep duration, and higher incidence of insomnia, daytime sleepiness, and sedative-hypnotic medication usage (P < 0.05). There was no significant difference between RLS-positive and RLS-negative patients in terms of renal failure pathology, dialysis frequency per week, dose of dialysis, duration of dialysis, renal transplantation, and history of diabetes and hypertension. Hemodialysis patients have a high prevalence of RLS which deserves special attention and specific treatment. PMID:25471049

    Introduction Chronic hemodialysis patients experience frequent and varied mucocutaneous manifestations in addition to hair and nail disorders. The aim of this study was to evaluate the prevalence of dermatological changes among patients with end-stage renal disease under hemodialysis in a hemodialysis unit in Tanta University hospitals over a period of 6 months, and to evaluate the relations of these dermatological disorders with the duration of hemodialysis as well as with different laboratory parameters in these patients. Patients and methods Ninety-three patients with end-stage renal disease on regular hemodialysis (56 males and 37 females) were selected and included in this cross-sectional, descriptive, analytic study. Their ages ranged from 18–80 years. All patients underwent thorough general and dermatological examinations. Laboratory investigations (complete blood counts, renal and liver function tests, serum parathormone levels, serum electrolytes, alkaline phosphatase, random blood sugar, and Hepatitis C virus (HCV) antibodies) were evaluated. Results This study revealed that most patients had nonspecific skin changes, including xerosis, pruritus, pallor, ecchymosis, hyperpigmentation, and follicular hyperkeratosis. Nail and hair changes were commonly found, especially half and half nail, koilonychia, subungal hyperkeratosis, melanonychia, onychomycosis, and brittle and lusterless hair. Mucous membrane changes detected were pallor, xerostomia, macroglossia, bleeding gums, aphthous stomatitis, and yellow sclera. There was a significant positive correlation between the presence of pruritus and serum parathormone level. There was a significant negative correlation between the presence of mucous membrane changes and hemoglobin level. Conclusion Nonspecific mucocutaneous manifestations are common in patients on hemodialysis, particularly xerosis, dyspigmentation, and pruritus.

    The disposition of naltrexone (NLT) (REVIA), an opioid antagonist intended for patients with impaired renal function and with severe intractable itching refractory to regular antipruritic therapy, was characterized. Hemodialysis effects on both efficacy and elimination of NLT also were assessed. We developed a simple, sensitive and selective reverse-phase high-performance liquid chromatographic (HPLC) method for measuring NLT plasma concentration in hemodialysis patients treated to relieve pruritus. NLT and the internal standard, naloxone (NLX) were extracted from plasma using a solid-phase extraction method with sep-pack C18 cartridge. The method was employed to determine both naltrexone pharmacokinetics and dialysability parameters during 4-h in dialyzed patients with chronic renal impairment. Thus, seven patients (2 men, 5 women) with end-stage renal disease and pruritus on regular hemodialysis were included. They received one tablet of NLT (Revia, 50 mg) orally prior dialysis session. The Cmax at the inlet and at the outlet the dialyzer were higher (255+/-117 ng/mL and 206+/-137 ng/ml respectively) in comparison with healthy subjects (9 - 44 ng/mL). The decrease hepatic first-pass metabolism of NLT consecutive to end-stage renal disease and the renal impairment could explain the increased levels of the drug in plasma. Tmax before and after dialysis plates remain unchanged as healthy subjects (approximately 1h). With regard to dialysability, a high dialyzer extraction ratio averating 30 % was found with a low dialysis clearance of 58.70+/-17 mL/min. The amount removed by dialysis is only 1.27 mg. We concluded that hemodialysis has little effect on NLT blood levels, and consequently on drug pharmacokinetics, when the drug is delivered to dialyzed patients following oral route. Thus, dosage adjustement is not required in the presence of advanced dialysis-dependant renal failure. In patients with end-stage renal disease, hemodialysis does not result in clinically

    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.

    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

    The effect of high-flux hemodialysis membranes on patient survival has not been unequivocally determined. In this prospective, randomized clinical trial, we enrolled 738 incident hemodialysis patients, stratified them by serum albumin ≤4 and >4 g/dl, and assigned them to either low-flux or high-flux membranes. We followed patients for 3 to 7.5 yr. Kaplan-Meier survival analysis showed no significant difference between high-flux and low-flux membranes, and a Cox proportional hazards model concurred. Patients with serum albumin ≤4 g/dl had significantly higher survival rates in the high-flux group compared with the low-flux group (P = 0.032). In addition, a secondary analysis revealed that high-flux membranes may significantly improve survival of patients with diabetes. Among those with serum albumin ≤4 g/dl, slightly different effects among patients with and without diabetes suggested a potential interaction between diabetes status and low serum albumin in the reduction of risk conferred by high-flux membranes. In summary, we did not detect a significant survival benefit with either high-flux or low-flux membranes in the population overall, but the use of high-flux membranes conferred a significant survival benefit among patients with serum albumin ≤4 g/dl. The apparent survival benefit among patients who have diabetes and are treated with high-flux membranes requires confirmation given the post hoc nature of our analysis. PMID:19092122

    Objective. The aim of study was to investigate the changes levels of serum ghrelin in HD patients and its relationship to some malnutrition markers compared with healthy controls. Methods. Forty-five patients on hemodialysis and forty healthy controls were studied. Biochemical parameters and serum ghrelin levels were measured. Both daily dietary intakes and body mass index (BMI) assessments were performed for evaluation of nutritional status. Results. Ghrelin concentrations were significantly reduced in patients undergoing hemodialysis when compared to healthy controls (5 ± 0.68 (1.1–18.5) pg/mL versus 7.8 ± 0.84 (2.4–18.3) pg/mL; P = 0.004). BMI and serum albumin in HD patients were markedly reduced compared to controls. The patients with an insufficient intake of energy and protein demonstrated slightly lower levels of serum ghrelin. A negative correlation between serum ghrelin concentration with age (r = −0.34, P = 0.02), BUN (r = −0.26, P < 0.01), and serum creatinine (r = −0.27, P < 0.01) was observed in HD patients. Conclusions. The findings suggest that decreased ghrelin levels in HD patients might be associated with anorexia. Further studies are needed to determine changes in serum ghrelin levels during dialysis and to clarify whether the decrease in ghrelin levels contributes to the malnutrition that is common in these patients.

    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

    [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.

    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.

  1. Predicting erythropoietin resistance in hemodialysis patients with type 2 diabetes

    PubMed Central

    2013-01-01

    Background Resistance to ESAs (erythropoietin stimulating agents) is highly prevalent in hemodialysis patients with diabetes and associated with an increased mortality. The aim of this study was to identify predictors for ESA resistance and to develop a prediction model for the risk stratification in these patients. Methods A post-hoc analysis was conducted of the 4D study, including 1015 patients with type 2 diabetes undergoing hemodialysis. Determinants of ESA resistance were identified by univariate logistic regression analyses. Subsequently, multivariate models were performed with stepwise inclusion of significant predictors from clinical parameters, routine laboratory and specific biomarkers. Results In the model restricted to clinical parameters, male sex, shorter dialysis vintage, lower BMI, history of CHF, use of ACE-inhibitors and a higher heart rate were identified as independent predictors of ESA resistance. In regard to routine laboratory markers, lower albumin, lower iron saturation, higher creatinine and higher potassium levels were independently associated with ESA resistance. With respect to specific biomarkers, higher ADMA and CRP levels as well as lower Osteocalcin levels were predictors of ESA resistance. Conclusions Easily obtainable clinical parameters and routine laboratory parameters can predict ESA resistance in diabetic hemodialysis patients with good discrimination. Specific biomarkers did not meaningfully further improve the risk prediction of ESA resistance. Routinely assessed data can be used in clinical practice to stratify patients according to the risk of ESA resistance, which may help to assign appropriate treatment strategies. Clinical trial registration The study was registered at the German medical authority (BfArM; registration number 401 3206). The sponsor protocol ID and clinical trial unique identified number was CT-981-423-239. The results of the study are published and available at http

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

    PubMed Central

    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

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

    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.

    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. PMID:20609186

    End-stage renal disease (ESRD) patients have extraordinarily high cardiovascular risk and mortality, yet the benefit of statins in this population remains unclear based on the randomized trials. We investigated the prognostic value of statins in a large, pure cohort of prospectively recruited patients with ESRD awaiting renal transplantation, and being followed up in a dedicated cardiac clinic. We prospectively collected demographic, clinical, laboratory, and pharmacological data on 423 consecutive ESRD patients on hemodialysis awaiting renal transplantation. Survival analysis was performed as a function of statin therapy. The baseline characteristics were as follows: age 57 ± 11 years, males 64%, diabetes mellitus in 68%, known coronary artery disease in 30%, left ventricular (LV) ejection fraction 61 ± 11%. Over a mean follow-up of 2 years, there were 43 deaths. Adjusted for age, gender, hypertension, body mass index, diabetes mellitus, coronary artery disease, smoking, and treatment with angiotensin converting enzyme inhibitor, β blocker, and antiplatelet medications, statin use was a predictor of lower mortality (hazard ratio 0.30, 95% confidence interval 0.11-0.79, p = 0.01). This beneficial effect of statin was supported by propensity score analysis (p = 0.02) and was consistent across all clinical subgroups. The benefit of statins seemed to be greater in those with LV hypertrophy and smoking. Statin therapy in hemodialysis patients awaiting renal transplant is independently associated with better survival supporting its use in this high-risk population. PMID:26060381

    2013-08-01

    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.

    We present a case of cardiac calcified amorphous tumor, a rare intracardiac non-neoplastic tumor, in a hemodialysis patient. A 72-year-old woman with no history of thromboembolic, malignant, or inflammatory disease presented with dyspnea. Echocardiography revealed a highly echoic, slightly mobile mass with an acoustic shadow originating from the mitral subvalvular apparatus, extending to the left ventricular outflow tract. She underwent surgical resection of the mass through the aortic valve, which was easily excised from the papillary muscle and chordae tendineae. Histopathologic examination revealed nodular calcium deposits on a background of amorphous degenerated fibrin material, consistent with calcified amorphous tumor. PMID:25742783

    In individuals with chronic kidney disease, surrogates of protein-energy wasting, including a relatively low serum albumin and fat or muscle wasting, are by far the strongest death risk factor compared with any other condition. There are data to indicate that hypoalbuminemia responds to nutritional interventions, which may save lives in the long run. Monitored, in-center provision of high-protein meals and/or oral nutritional supplements during hemodialysis is a feasible, inexpensive, and patient-friendly strategy despite concerns such as postprandial hypotension, aspiration risk, infection control and hygiene, dialysis staff burden, diabetes and phosphorus control, and financial constraints. Adjunct pharmacologic therapies can be added, including appetite stimulators (megesterol, ghrelin, and mirtazapine), anabolic hormones (testosterone and growth factors), antimyostatin agents, and antioxidative and anti-inflammatory agents (pentoxiphylline and cytokine modulators), to increase efficiency of intradialytic food and oral supplementation, although adequate evidence is still lacking. If more severe hypoalbuminemia (<3.0 g/dL) not amenable to oral interventions prevails, or if a patient is not capable of enteral interventions (e.g., because of swallowing problems), then parenteral interventions such as intradialytic parenteral nutrition can be considered. Given the fact that meals and supplements during hemodialysis would require only a small fraction of the funds currently used for dialysis patients this is also an economically feasible strategy.

    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.

    We here present the results of ultrasonographic (US) evaluations on the alteration of renal diameter of chronic HD patients. Of 109 outpatient HD patients who had neither severe acquired cystic disease of the kidney nor hereditary polycystic kidney disease, we performed US two or three times to measure their maximum renal diameter (mean of both kidneys), and the yearly alteration rate was calculated. The average interval of the two measurements was 35.9 months, and the average HD duration from the HD induction to the first measurement was 29.5 months. The average decrease rate of renal diameter was 4.34 ± 0.4 (SE) mm/year. No statistical difference was seen on the decrease rate in relation to gender, age and original disease (among three groups, glomerulonephritis and IgA nephropathy, diabetes, and others including hypertension). However, the decrease rate was large when the first measurement was close to the induction of hemodialysis, suggesting that the alteration rate reduced according to the hemodialysis vintage (5.3 ± 0.8 mm/year, first measurement not more than 10 months after induction of HD and 1.5 ± 1.6 mm/year, first measurement more than 80 months after induction of HD). Renal diameter decreased approximately 4.3 mm each year, and the decrease rate slowed as the length of time on dialysis increased. PMID:24967236

    Hemodialysis (HD) patients are subjected to a number of physical and mental stresses. Physicians might be unaware of some of these problems. We assessed our patients' opinion about the service provided at the dialysis unit. Our unit has 89 patients on HD. A questionnaire exploring our patients' opinion relative to the service provided was prepared. The patients were asked to fill-in the questionnaire in a confidential manner. Questionnaires were then collected and examined while unaware of patient identities. Sixty-nine patients (77.5%) responded to the questionnaire. Eight patients (11.6%) revealed their names on the questionnaire. According to the questionnaire, the patients were asked to assess the service of each service by choosing one of the following grades: "excellent," "mediocre" or "bad." For the whole group of contributing patients, there were 563 "excellent," 85 "mediocre" and five "bad" choices in addition to 37 blank "no comment" choices. Food service had the least percentage (68%) of evaluation as "excellent," while doctor' performance got the highest excellent evaluation (85.5%). Thirty-five patients (50.7%) added further comment(s). An audit meeting was conducted to discuss these results. Exploring the opinion of patients on HD might uncover some areas of dissatisfaction and help in improving the provided service. We recommend widespread usage of questionnaires to assess patient satisfaction as well as to assess other health-care aspects. PMID:25579719

    Introduction Cognitive impairment is a major, but underdiagnosed, risk factor for negative outcomes in patients with chronic kidney disease (CKD). The main goal of this study was to evaluate, for the first time, the relationship between arterial stiffness and cognitive impairment in a cohort of hemodialysis patients. Methods We prospectively analyzed the cognitive function and pulse wave velocity (PWV) of 72 hemodialysis patients, mean age 56.54 ± 13.96 y, from two Romanian dialysis centers. We administered to all patients the Mini Mental State Examination (MMSE), Trail Making Test Part-A (TMTA) and Part-B (TMTB), and Mini-Cog Test. Radial arterial waveforms during 40 cardiac cycles were recorded in each patient. Findings Mean MMSE score was 25.13 ± 3.47, mean MiniCog score was 3.51 ± 1.18, mean TMTA (sec) was 103.77 ± 53.13 and mean TMTB (sec) was 214.93 ± 112.25. In linear unadjusted regression, PWV values were associated with worse MMSE scores (β = -0.36, P = 0.001, 95% CI: -0.68 to -0.17), and MiniCog scores (β = -0.26, P = 0.02, 95% CI: -0.19 to -0.01). Also, PWV value was significant associated with TMTA test, but not with TMTB. After further adjustments, PWV remained a strong predictor for cognitive impairment measured by MMSE, TMTA, MiniCog, but not for TMTB. Discussion Cognitive impairment was associated with higher PWV values in our cohort. Further evidence is needed in order to support arterial stiffness as a long-term predictor for cognitive decline in ESRD patients. PMID:26861856

    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

    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

    Heparin-induced thrombocytopenia type II (HIT) is a clinicopathologic syndrome in which one or more clinical events are temporally related to heparin administration and caused by HIT antibodies. There are at least five different types of clinical events that are associated with HIT: thrombocytopenia; thrombosis; skin necrosis at heparin injection site, venous limb gangrene; and an acute systemic reaction that occurs 5-30 min after intravenous bolus of heparin. HIT typically presents 5-14 days after initiation of heparin therapy, later onset is unusual. Heparin is a routine anticoagulant in hemodialysis but administration is different than in surgical and other medical population. Doses are lower and administered every other day, yet hemodialysis patients receive heparin for years. Relationship between dialysis vintage and HIT-antibody positivity has been analyzed in two studies. In national survey of HIT in hemodialysis population of the United Kingdom mean time between starting hemodialysis and development of HIT was 61 days (5-390 days). Japanese authors also found greatest incidence of HIT antibody positivity in patients who were on hemodialysis for less than 1 year, none of patients on hemodialysis for more than 10 years was HIT-antibody positive. We present a case of 70-years old female who developed HIT after 24 years of hemodialysis and exposure to heparin. First 22 years she was receiving unfractionated heparin for anticoagulation during hemodialysis sessions. Afterwards her therapy was changed to low molecular weight heparin. Last 12 years she has tunneled cuffed catheter which was also filled with unfractionated heparin. She had a history of severe renal osteodistrophy and severe aortal valve stenosis, hypothyreosis, thrombosis of both subclavian veins and partial colon resection due to mesenterial artery thrombosis. Her thrombocyte count was low, but despite extensive work-up which included HIT antibody detection, no cause could be identified. She

    Pseudomonas oryzihabitans (P. orizyhabitans) has already been reported both as a human and a zoonotic pathogen. A few cases of P. orizyhabitans bacteremia have been reported among patients who underwent peritoneal dialysis. P. orizyhabitans bacteremia has never been reported among patients on hemodialysis. We report the first case of P. orizyhabitans bacteremia in a chronic hemodialysis patient; this patient did not have a central venous catheter angioaccess as a potential portal of entry.

    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

    “Cocoon abdomen” or sclerosing encapsulating peritonitis is a rare cause of intestinal obstruction. It has been described in patients on continuous ambulatory peritoneal dialysis. The exact etiology is unknown, but pathogenesis rests on chronic peritoneal inflammation. No case has been reported so far in patients on hemodialysis. We hereby report a case of cocoon abdomen presenting as refractory ascites with intestinal obstruction in a patient on maintenance hemodialysis. PMID:26937080

    Introduction End stage renal disease (ESRD) affects patient’s physical and psychological health. Depression is the most common psychiatric illness among patients with ESRD. This study aimed to identify the prevalence of depressive symptoms among patients undergoing peritoneal (PD) and hemodialysis (HD), also to correlate these symptoms with the demographic data. Methods this is a cross-sectional study that includes 133 PD patients and 133 HD patients attending the King Fahad Dialysis Center at King Saud Medical Complex (KSMC), Riyadh, Saudi Arabia. Socio-demographic data were documented. Depression was evaluated by using the zung self- rating depression scale (Zung SDS). Results using the Zung SDS; the prevalence of depression was significantly higher among PD patients (98.5%) in compare with HD patients (83.5%). Conclusion the study reveals that there is a high prevalence of depressive symptoms among PD and HD patients. This will lead us to think of adding a system for screening, diagnosis and treatment of depression for all dialysis patients to improve their life. PMID:25901128

    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. PMID:26131325

    Patients receiving conventional hemodialysis have high hospitalisation rates, poor quality of life and survival compared to the general population. Many centres around the world are providing longer hours of hemodialysis - short daily hemodialysis and nocturnal hemodialysis - with a view to improving patient survival and quality of life. Studies have shown that nocturnal haemodiaysis is more effective than conventional hemodialysis in clearing most small, middle and larger molecule toxins and suggest nocturnal dialysis enhances patient survival and quality of life. Concerns include patient acceptance, vascular access related complications and increased cost. The purpose of this review is to examine the advantages and drawbacks of nocturnal dialysis, with a focus on applicability to India where the renal physician has to face cultural and economic barriers, erratic power supply and poor water quality.

    We report a rare case of manganese (Mn)-induced parkinsonism in a patient on maintenance hemodialysis therapy who complained of gait disturbance and dysarthria. His symptoms and abnormal magnetic resonance imaging (MRI) findings of the brain were thought to be caused, at least in part, by long-term ingestion of a health supplement (Chlorella extract) that contained 1.7 mg of Mn in the usual daily dose. Elevated serum and cerebrospinal fluid Mn levels were detected, and brain MRI showed areas of abnormal intensity in the bilateral basal ganglia (low intensity on T1-weighted images and high intensity on T2-weighted images). Edetic acid infusion therapy dramatically improved the MRI abnormalities, after which his symptoms gradually improved 4 months later. PMID:16183431

    Aim. To assess the degree of satisfaction among hemodialysis patients and the factors influencing this satisfaction. Methods. Patients were recruited from 3 Saudi dialysis centers. Demographic data was collected. Using 1 to 10 Likert scale, the patients were asked to rate the overall satisfaction with, and the overall impact of, their dialysis therapy on their lives and to rate the effect of the dialysis therapy on 15 qualities of life domains. Results. 322 patients were recruited (72.6% of the total eligible patients). The mean age was 51.7 years (±15.4); 58% have been on dialysis for >3 years. The mean Charlson Comorbidity Index was 3.2 (±2), and Kt/V was 1.3 (±0.44). The mean satisfaction score was (7.41 ± 2.75) and the mean score of the impact of the dialysis on the patients' lives was 5.32 ± 2.55. Male patients reported worse effect of dialysis on family life, social life, energy, and appetite. Longer period since the commencement of dialysis was associated with adverse effect on finances and energy. Lower level of education was associated with worse dialysis effect on stress, overall health, sexual life, hobbies, and exercise ability. Conclusion. The level of satisfaction is affected by gender, duration on dialysis, educational level, and standard of care given. PMID:21152200

  13. Complication of diagnostic pleural aspiration: is it of value in hemodialysis patients?

    Pleural effusions are common in hemodialysis patients and are associated with significant morbidity. Diagnostic pleural aspiration and subsequent biochemical analysis can be used to differentiate exudates and transudates. In particular, Light's criteria have been validated in the general population although their efficacy in hemodialysis patients is unclear. Furthermore, aspiration is not without risk; we report the case of a life-threatening thoracic bleed as a complication of diagnostic thoracocentesis in a hemodialysis patient, in whom a transudative effusion was misclassified according to Light's criteria. Retrospective examination of a further 22 aspirations in hemodialysis patients suggests that biochemical analysis of pleural fluid in this group is of limited value. Careful clinical and radiological assessment may be of greater value in determining individuals who may benefit from formal drainage, rather than diagnostic aspiration with its attendant risks.

    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.

    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

    A 64-year-old male on regular hemodialysis who was a human T lymphotrophic virus Type I (HTLV-I) carrier developed cryptococcal pleuritis. The initial manifestations of the present case were a persistent cough and the accumulation of unilateral pleural effusion. A culture of the pleural fluid of the patient grew cryptococcus neoformans and a test for antigens against cryptococcus neoformans in the pleural fluid was also positive, therefore, cryptococcal pleuritis was diagnosed. Pleural cryptococcosis per se is rare and it is extremely rare for a dialysis patient to develop pleural cryptococcosis. To our knowledge, only a few cases of cryptococcal pleuritis have so far been reported in patients on dialysis. Furthermore, an isolated occurrence of cryptococcal pleuritis with no cryptococcal pulmonary parenchymal lesions, as was seen in the present case, is rare because cryptococcal pleuritis is usually associated with underlying cryptococcal pulmonary parenchymal lesions. Patients on chronic dialysis are susceptible to developing pleural effusion from many etiologies such as congestive heart failure, infection (tuberculosis, bacterial, viral, parasitic, fungal), collagen vascular disease, drug reaction, metastasis, or uremia itself. Cryptococcal pleuritis developing in a dialysis patient is extremely rare, but physicians should consider cryptococcal infection as a possible cause when pleural effusion develops in a dialysis patient and no other cause is identified, as occurred in the present case.

    Premature atherosclerosis represents the main cause of mortality among end-stage renal disease patients (ESRD). Increased inflammation and oxidative stress are involved in initiation and progression of the atherosclerotic plaque. As foam cells are capable of producing significant amounts of inflammatory mediators and free radicals, we hypothesized that foam cells from uremic patients could produce more inflammation and oxidative stress than foam cells from normal people and be, somehow, involved in the accelerated atherosclerosis of uremia. To test this hypothesis, the levels of a few markers of inflammation and oxidative stress: Tumor necrosis factor-α, inducible nitric oxide synthase, malondialdehyde, nitric oxide by-products were measured in the supernatants of macrophage-derived foam cells cultures from 18 hemodialysis patients and 18 apparently healthy individuals controls. Malondialdehyde levels in the supernatant of cell cultures (macrophages stimulated or not with native and oxidized lipoprotein) were significantly increased in uremic patients; no statistically significant difference was found between the supernatant concentrations of nitric oxide by-products, inducible nitric oxide synthase activity, and tumor necrosis factor-α between patients and controls. Our results, obtained with human macrophages and macrophage-derived foam cells, are compatible with the theory that increased cellular oxidative stress and inflammatory activity in ESRD patients could accelerate the atherosclerotic process. The present culture protocol showed it is possible to use human mononuclear cells to evaluate the oxidative metabolism of foam cells, which are considered to be the initial step of atherosclerotic lesions.

    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.

    Hepatitis C virus has substantial heterogeneity of genotypes throughout the world. The aim of this study was to determine the frequency of HCV genotypes, risk factors and clinical implications in cases of hemodialysis living in Tehran. A total of 155 patients treated by hemodialysis, who had been identified to be anti-HCV positive at 45 medical centers in Tehran, were enrolled. Genotyping was using restriction fragment length polymorphism (RFLP) on HCV-RNA positive samples. HCV-RNA was detected in 66 (42.6%) patients. Genotyping of HCV-RNA positive serum samples demonstrated that subtypes 3a and 1a were predominant accounting for 30.3 and 28.8%, respectively. The distribution of other HCV genotypes showed genotype 1b, 18.2%; genotype 4, 16.7%; mixed genotypes 1a and 1b, 3%; and genotype 3b, 3%. Genotype 2 was not detected in this study. Statistically significant differences were identified between HCV infected and non-HCV infected patients regarding history of hemodialysis unit changes more than two times (P = 0.01), and history of hemodialysis for more than 20 years (P = 0.02). However, blood transfusion, mean duration of hemodialysis therapy and the history of solid organ transplantation did not differ between these two groups. This study indicates that the dominant HCV genotypes among patients treated by hemodialysis living in Tehran were 3a and 1a, and considering previous reports from the general population, genotype 4 was strongly associated with hemodialysis. The duration of treatment by hemodialysis and, in turn, more hemodialysis unit changes will lead to more frequent HCV infections. PMID:16555284

    Background Long-term hemodialysis patients are prone to an exceptionally high burden of cardiovascular disease and mortality. The novel temperature based technology of Digital Thermal Monitoring (DTM) of vascular reactivity appears associated with the severity of coronary artery disease in asymptomatic population. We hypothesized that in hemodialysis patients the DTM and coronary artery calcium (CAC) score have a gradient association that follows that of subjects without kidney disease. Methods We examined the cross-sectional DTM-CAC associations in a group of long-term hemodialysis patients and their 1:1 matched normal counterparts, Area under the curve for temperature (TMP-AUC), the surrogate of the DTM index of vascular function, was assessed after a 5-minute arm-cuff reactive hyperemia test. Coronary calcium score was measured via EBCT or MDCT scan. Results We studied 105 randomly recruited hemodialysis patients (age:58±13 years, 47 % men) and 105 age- and gender-matched controls. In hemodialysis patients vs. controls TMP-AUC was significantly worse (114±72 vs. 143±80. p=0.001) and CAC score was higher (525±425 vs. 240±332, p<0.001). Hemodialysis patients were 14 times more likely to have CAC score >1000 as compared with controls. After adjustment for known confounders, the relative risk for case vs. control for each standard deviation decrease in TMP-AUC was 1.46 (95%CI: 1.12-1.93, p=0.007). Conclusions Vascular reactivity measured via the novel DTM technology is incrementally worse across CAC scores in hemodialysis patients, in whom both measures are even worse than their age- and gender matched controls. The DTM technology may offer a convenient and radiation-free approach to risk-stratify hemodialysis patients. PMID:22962941

    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.

    2014-01-01

    Background Atherosclerotic cardiovascular disease (CVD) is the most common cause of morbidity and mortality among hemodialysis (HD) patients. It has been attributed, among other causes, to hypertension and dyslipidemia. The aim of the present study was to investigate the effect of a year-long consumption of Pomegranate juice (PJ), on two traditional cardiovascular (CV) risk factors: hypertension and lipid profile, as well as on cardiovascular events. Methods 101 HD patients were randomized to receive 100 cc of PJ (0.7 mM polyphenols) or matching placebo juice, three times a week for one year. The primary endpoints were traditional CV risk factors; blood pressure and lipid profile. Systolic, diastolic and pulse pressure, plasma levels of triglycerides (TG), high density lipoprotein (HDL), low density lipoprotein (LDL) and total cholesterol were monitored quarterly during the study year. Secondary endpoint was incidence of cardiovascular events. Results PJ consumption yielded a significant time response improvement in systolic blood pressure, pulse pressure, triglycerides and HDL level; an improvement that was not observed in the placebo intake group. These beneficial outcomes were more pronounced among patients with hypertension, high level of triglycerides and low levels of HDL. Conclusion Regular PJ consumption by HD patients reduced systolic blood pressure and improved lipid profile. These favorable changes may reduce the accelerated atherosclerosis and high incidence of CVD among HD patients.

    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

    High concentrations of HDL cholesterol are considered to indicate efficient reverse cholesterol transport and to protect from atherosclerosis. However, HDL has been suggested to be dysfunctional in ESRD. Hence, our main objective was to investigate the effect of HDL cholesterol on outcomes in maintenance hemodialysis patients with diabetes. Moreover, we investigated the associations between the major protein components of HDL (apoA1, apoA2, and apoC3) and end points. We performed an exploratory, post hoc analysis with 1255 participants (677 men and 578 women) of the German Diabetes Dialysis study. The mean age was 66.3 years and the mean body mass index was 28.0 kg/m2. The primary end point was a composite of cardiac death, myocardial infarction, and stroke. The secondary end point included all-cause mortality. The mean duration of follow-up was 3.9 years. A total of 31.3% of the study participants reached the primary end point and 49.1% died from any cause. HDL cholesterol and apoA1 and apoC3 quartiles were not related to end points. However, there was a trend toward an inverse association between apoA2 and all-cause mortality. The hazard ratio for death from any cause in the fourth quartile compared with the first quartile of apoA2 was 0.63 (95% confidence interval, 0.40 to 0.89). The lack of an association between HDL cholesterol and cardiovascular risk may support the concept of dysfunctional HDL in hemodialysis. The possible beneficial effect of apoA2 on survival requires confirmation in future studies. PMID:25012163

    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

    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.

    Background: Restless legs syndrome (RLS) may be associated with increased morbidity and mortality among end-stage renal disease (ESRD) patients; however, it is a disorder that is neglected in dialysis centers. Objectives: The goal of this study was to investigate the clinical factors associated with RLS among ESRD patients. Patients and Methods: This cross-sectional study was conducted on ESRD patients undergoing maintenance hemodialysis (HD) in three HD centers in Ahvaz city in Southwest Iran. Blood samples were obtained prior to a dialysis session to check the routine laboratory test results and assess the adequacy of dialysis. The presence of RLS was assessed by using the international RLS study group (IRLSSG) diagnostic criteria. The IRLSSG rating scale was also used to evaluate the severity of the RLS symptoms. Results: Of the 139 HD patients enrolled in this study, 60 were female (43.2%) and 79 were male (56.8%), with a mean age of 51.82 ± 13.31 years. The prevalence of RLS was 15.8% (22 patients), with 50% of them (11 patients) having severe or very severe symptoms. There was a significant relationship between RLS and longer durations of dialysis (P < 0.001). The mean level of serum ferritin was lower in patients without RLS, but it was not significant (P = 0.065). No significant differences were found according to age, gender, dialysis shifts, and hemoglobin (Hb) level among patients with and without RLS. Conclusions: We conclude that a significant percentage of ESRD patients undergoing maintenance HD have severe or very severe RLS symptoms. The presence of RLS is associated to longer durations of dialysis. PMID:26866010

    Congestive heart failure is a well-recognized complication of hemodialysis arteriovenous fistula. Symptoms of dyspnea are usually associated with signs of congestive heart failure including pulmonary edema, pleural effusions, lower extremity edema, and liver enlargement, to name a few. We present a case of a gentleman with end-stage renal disease on chronic hemodialysis, which developed acute bilateral transudative pleural effusions in the absence of other signs of systemic venous congestion, associated with pulmonary venous congestion. We also discuss the pathogenesis and role of hemodialysis in management of this patient. PMID:23036038

    Data on dolutegravir removal by hemodialysis are lacking. 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.

    The aim of this study is to explore how nurses perceive patient participations of patients over 75 years old undergoing hemodialysis treatment in dialysis units, and of their next of kin. Ten nurses told stories about what happened in the dialysis units. These stories were analyzed with critical discourse analysis. Three discursive practices are found: (1) the nurses' power and control; (2) sharing power with the patient; and (3) transferring power to the next of kin. The first and the predominant discursive practice can be explained with an ideology of paternalism, in which the nurses used biomedical explanations and the ethical principle of benefice to justify their actions. The second can be explained with an ideology of participation, in which the nurses used ethical narratives as a way to let the patients participate in the treatment. The third seemed to involve autonomous decision-making and the ethical principle of autonomy for the next of kin in the difficult end-of-life decisions. PMID:22323398

    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

    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/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

    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.

    Increased body mass index (BMI) confers a survival advantage in maintenance hemodialysis (MHD) patients. Diabetic (DM) patients undergoing MHD have worse survival. There are limited studies examining the effect of obesity on the risk of death among MHD patients with diabetes. Ninety-eight MHD patients were studied for median follow-up time of 78 months. Patients were classified according to the presence of obesity (BMI ≥ 30 kg/m2) or DM. Primary outcome was all-cause mortality. Cox regression was used to evaluate the effect of obesity on time to death. Effect modification and mediation analysis were also performed. Mean age was 49 ± 13 years, 66% were male, 48% were obese and 34% were diabetic. Mortality rates (per 100 person years) were: 3.4 for non-diabetic obese, 8.6 for non-diabetic non-obese, 14.3 for diabetic non-obese and 18.1 for diabetic obese patients. Log-rank comparing diabetic obese versus non diabetic obese was significant (p=0.007). Diabetes was associated with an increased risk of mortality after adjustment for potential mediators. Effect modification of obesity in the mortality risk was different between patients with and without diabetes. With adjustment for adipokines, a greater effect modification by diabetes was observed whereas adjustment for inflammatory marker did not influence the effect modification. Diabetic obese MHD patients have increased mortality risk compared to non-diabetic obese. Obesity does not offer survival benefits in Diabetic obese MHD patients and potentially may have detrimental effects. Larger studies evaluating the effect of adipokines and obesity in outcomes in the diabetic MHD population need to be undertaken. PMID:24467439

    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.

    Context: Coronary artery disease is highly prevalent among patients with end stage renal disease/hemodialysis (ESRD/HD) and coronary percutaneous interventions (PCI) has been increased by nearly 50% over the past decade. After PCI with stent placement, guidelines recommend dual antiplatelet therapy (DAPT), but no specifically tailored pharmacotherapy approach is outlined for this frail population, mostly excluded from large randomized clinical trials (RCTs). Evidence Acquisition: We reviewed current evidences on the use of antiplatelet therapy in patients with ESRD/HD undergoing PCI, focusing on the efficacy and safety of specific agents and their indications for detailed clinical settings. Results: Clinical setting in HD patients is the principal determinant of the type, onset, combination and duration of the DAPT. However, irrespective clinical setting, in addition to aspirin, clopidogrel is currently the most used antiplatelet agent even if no information derived from RCTs are available in ESRD. Due to the large experience acquired in routine clinical practice, the awareness of safety is higher for clopidogrel than newer antiplatelet agents. Because of lack of data, the use of prasugrel and ticagrelor is actually not recommended. However, in case of high ischemic and acceptable bleeding risk, they may be selectively used in ESRD/HD. Conclusions: This investigation might contribute to delineate the best treatment options for this high risk population. PMID:26528445

    Background Traditionally, a radial or brachial arterial approach is unadvisable in hemodialysis patients. Consequently, coronary angiography or angioplasty is usually performed via a femoral artery approach in these patients, who carry a higher risk of vascular access complications. In hemodialysis patients, arteriovenous grafts (AVG) are created for repeated punctures; however, the feasibility and safety of a trans-AVG approach for coronary angiography or angioplasty remains unclear. Methods In our institution, cardiac catheterizations were attempted via AV grafts in hemodialysis patients with a U-shaped forearm AVG. We retrospectively identified coronary angiography or angioplasty procedures in hemodialysis patients from a computer-based database in our hospital. The procedure details and outcomes were obtained from review of the clinical, angiographic and hemodialysis records. Results From 2008 to 2013, 167 procedures in hemodialysis patients were identified from 2866 diagnostic or interventional coronary procedures in our institution. Out of these, 24 procedures in 17 patients were performed via a trans-AVG approach. In all AVG procedures, a 6F 16-cm or 7F 10-cm sheath was placed from the AVG into the brachial artery. All diagnostic procedures were successfully performed. In 14 procedures, the patients also underwent angioplasty and all of the angioplasty procedures were successful. There was no arterial spasm, arterial dissection, puncture site hematoma, or acute thrombosis of the AVG during or after the procedures. Conclusions A trans-AVG approach appears to be a feasible and safe route for coronary angiography or angioplasty in hemodialysis patients with a U-shaped forearm AVG. However, further studies with a larger patient number are necessary. PMID:27122921

    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.

    Although patients on hemodialysis require effective education for self-care, several issues associated with the process raise barriers that make learning difficult. Computer-based education can reduce these problems and improve the quality of education. This study aims to develop and validate a theory-based multimedia application to educate Persian patients on hemodialysis. The study consisted of five phases: (1) content development, (2) prototype development 1, (3) evaluation by users, (4) evaluation by a multidisciplinary group of experts, and (5) prototype development 2. Data were collected through interviews and literature review with open-ended questions and two survey forms that consisted of a five-level scale. In the Results section, patient needs on hemodialysis self-care and related content were categorized into seven sections, including kidney function and failure, hemodialysis, vascular access, nutrition, medication, physical activity, and living with hemodialysis. The application designed includes seven modules consisting of user-controlled small multimedia units. During navigation through this application, the users were provided step-by-step information on self-care. Favorable scores were obtained from evaluations by users and experts. The researchers concluded that this application can facilitate hemodialysis education and learning process for the patients by focusing on their self-care needs using the multimedia design principles.

    Background and objectives Levels of asymmetric dimethylarginine, an inhibitor of nitric oxide synthase, are elevated in kidney disease and associated with mortality in white European hemodialysis populations. Nitric oxide production and degradation are partially genetically determined and differ by racial background. No studies have measured asymmetric dimethylarginine in African Americans on dialysis and assessed whether differences exist in its association with mortality by race. Design, setting, participants, & measurements Asymmetric dimethylarginine was measured in 259 patients on maintenance hemodialysis assembled from 2004 to 2012 in Boston area outpatient centers. Cox proportional hazards models were used to determine the association between asymmetric dimethylarginine and all-cause mortality, and an interaction with race was tested. Results Mean (SD) age was 63 (17) years, 46% were women, and 22% were African American. Mean asymmetric dimethylarginine in non–African Americans was 0.79 µmol/L (0.16) versus 0.70 µmol/L (0.11) in African Americans (P<0.001); 130 patients died over a median follow-up of 2.3 years. African Americans had lower mortality risk than non–African Americans (hazard ratio, 0.27; 95% confidence interval, 0.15 to 0.50) that was robust to adjustment for age, comorbidity, and asymmetric dimethylarginine (hazard ratio, 0.35; 95% confidence interval, 0.17 to 0.69). An interaction was noted between race and asymmetric dimethylarginine (P=0.03), such that asymmetric dimethylarginine was associated with higher mortality in non–African Americans (adjusted hazard ratio, 1.29; 95% confidence interval, 1.06 to 1.57 per 1 SD higher asymmetric dimethylarginine) but not in African Americans (adjusted hazard ratio, 0.57; 95% confidence interval, 0.28 to 1.18). Additional adjustment for fibroblast growth factor 23 partially attenuated the association for non–African Americans (adjusted hazard ratio, 1.22; 95% confidence interval, 0.98 to 1

    Examination of 109 patients with chronic renal disease undergoing hemodialysis revealed significant impairment of arterial wall distensibility (accordingly, decreased Peterson's and Young's elastic moduli, distensibility coefficient). The relative thickness of the common carotid artery and pulse wave velocity were significantly greater than in practically healthy subjects. Independent factors influencing arterial wall rigidity included age, arterial pressure, total cholesterol and homocystein, stable metabolites of nitric oxide, creatinine, calcium, phosphorus levels, calcium x phosphorus product, duration of hemodialysis, interdialytic weight gain.

    In the last five year, 198 critic patients developed acute renal failure, requiring hemodialysis in the hospital. 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

    Dabigatran is a direct thrombin inhibitor indicated for stroke and systemic embolism prevention in patients with non-valvular atrial fibrillation. No reversal agent exists, but hemodialysis has been proposed as dabigatran removal method. We report a case of an 80-year-old man presenting hemorrhage with dabigatran overdose caused by obstructive acute renal failure. Before nephrostomy, several hemodialysis sessions were necessary to remove dabigatran probably because of its large volume of distribution. PMID:24378048

    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

    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 objectives of this study were to assess the prevalence of chronic obstructive pulmonary disease (COPD) in hemodialysis patients with spirometry and to examine the effects of fluid removal by hemodialysis on lung volumes. Patients ≥18 years at two Danish hemodialysis centers were included. Forced expiratory volume in one second (FEV1 ), forced vital capacity (FVC), and FEV1 /FVC ratio were measured with spirometry before and after hemodialysis. The diagnosis of COPD was based on both the GOLD criteria and the lower limit of normal criteria. There were 372 patients in treatment at the two centers, 255 patients (69%) completed spirometry before dialysis and 242 of these (65%) repeated the test after. In the initial test, 117 subjects (46%) had airflow limitation indicative of COPD with GOLD criteria and 103 subjects (40.4%) with lower limit of normal criteria; COPD was previously diagnosed in 24 patients (9%). Mean FVC and FEV1 decreased mildly after dialysis (FVC: 2.84 to 2.79 L, P < 0.01. FEV1 : 1.97 to 1.93 L, P < 0.01) Hemodialysis did not affect the FEV1 /FVC ratio or number of subjects with airflow limitation indicative of COPD (113 vs. 120, P = 0.324; n = 242). COPD is a frequent and underdiagnosed comorbidity in patients on chronic hemodialysis. Spirometry should be considered in all patients on dialysis in order to address dyspnea adequately. Hemodialysis induced a small fall in mean FEV1 and FVC, which was more pronounced in patients with little or no fluid removal, but the FEV1 /FVC ratio and the number of subjects with airflow limitation indicative of COPD were not affected by dialysis.

    End-stage renal failure patients exhibit a high incidence of genetic damage and genomic instability. Part of this genetic damage is assumed to be caused by the hemodialysis (HD) procedure. To reduce these effects, different alternative HD procedures have been proposed, such as the use of high efficiency convective therapies to improve the reactive oxygen species/antioxidant ratio. To determine the efficiency of online hemodiafiltration (HDF) technique on the levels of DNA damage, we have measured the frequency of micronucleus in peripheral blood lymphocytes of 33 individuals moving from low-flux HD to post-dilution online HDF. In addition to basal levels of genetic damage, potential changes in radiosensitivity were measured as indicators of genomic instability. Plasma antioxidant capacity was also determined. Second samples were obtained after 6 months on the HDF protocol. Results indicate that moving to online HDF therapy produce a significant reduction of the basal levels of genetic damage, but does not affect the genomic instability status. In addition, a greater increase in plasma antioxidant capacity was observed. In spite of the lack of correlation between these parameters, our results confirm the usefulness of the online HDF technique as a way to reduce DNA damage in HD patients. PMID:26285921

    Background and objectives: Although uremic pruritus (UP) is a highly prevalent complication of chronic kidney disease, it remains poorly characterized. There have been no longitudinal studies of natural history, and no health-related quality of life (HR-QOL) instruments have been developed for UP. The objectives of this study were to describe the natural history of UP, to compare rating scales of itching intensity, and to assess usefulness and validity of HR-QOL instruments for UP. Design, setting, participants, & measurements: The intensity, severity, and effects of pathologic itching on HR-QOL were assessed prospectively in 103 patients with UP on chronic hemodialysis. Outcome measures were obtained at scheduled intervals over 3.5 months. Results: Itching daily or nearly daily was reported by 84% of patients and had been ongoing for >1 year in 59%. In 83%, pruritus involved large, nondermatomal areas with striking bilateral symmetry. Two thirds of the patients were using medications such as antihistamines, steroids, and various emollients without satisfactory relief of itching. Statistically significant associations were found among itching intensity, severity, and HR-QOL measures in domains such as mood, social relations, and sleep. Among patients with moderate-to-severe UP, changes in itching intensity of 20% or greater were associated with significant reductions in HR-QOL measures. Conclusions: This first longitudinal study of UP describes key features of UP and its effect on HR-QOL. The assessment instruments we have developed are easily used, are responsive to changes in UP intensity, and should facilitate clinical evaluation and research to meet the needs of afflicted patients.

    Background Chronic kidney disease is an increasing health problem worldwide and in its final stage (stage V) can only be treated by renal replacement therapy, mostly hemodialysis. Hemodialysis has a major influence on the everyday life of patients and many patients report dissatisfaction with treatment. Little is known about which aspects of treatment are considered important by hemodialysis patients. The objective of this study was to rate the relative importance of different outcomes for hemodialysis patients and to analyze whether the relative importance differed among subgroups of patients. Patients and methods Within the framework of a yearly questionnaire which is distributed among patients receiving hemodialysis by the largest hemodialysis provider in Germany, we assessed the relative importance of 23 outcomes as rated on a discrete visual analog scale. Descriptive statistics were used to rank the outcomes. Subgroup analyses were performed using Mann–Whitney U or Kruskal–Wallis tests. Results Questionnaires of 4,518 hemodialysis patients were included in the analysis. The three most important outcomes were safety of treatment, health-related quality of life, and satisfaction with care. Further important outcomes were hospital stays, accompanying symptoms, hemodialysis duration, and the improvement or preservation of a good emotional state. Age, profession, and education had the strongest influence on relevant differences of preferences for outcomes; no relevant influence of sex or comorbidity was observed. Conclusion Outcomes concerning the delivery or provision of care and aspects influencing quality of life are rated by patients to be at least as important as clinical outcomes. Many of the outcomes judged to be important by the patients are not regularly considered in research, evaluation studies, or quality programs. PMID:26170634

    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

    Large size, protein binding and intracellular sequestration are well known to limit dialytic removal of compounds. In studying the normal renal and dialytic handling of trimethylamine oxide (TMAO), a molecule associated with cardiovascular disease in the general population, we discovered two largely unrecognized additional limitations to sustained reduction of a solute by chronic hemodialysis. We measured solute levels and handling in subjects on chronic hemodialysis (ESRD, n = 7) and compared these with levels and clearance in normal controls (NLS, n = 6). The ESRD patients had much higher peak predialysis plasma levels of TMAO than NLS (77 ± 26 vs 2±1 μM, mean ± SD, p<0.05). For comparison, predialysis BUN levels in ESRD subjects were 45±11 mg/dl and 15±3 mg/dl in NLS. Thus TMAO levels in ESRD average about 40 fold those in NLS while BUN is 3 fold NLS. However, the fractional reduction of TMAO concentration during dialysis, was in fact greater than that of urea (86±3 vs 74±6%, TMAO vs urea, p < 0.05) and its dialytic clearance while somewhat lower than that of urea was comparable to creatinine’s. Also production rates were similar (533±272 vs 606 ± 220 μ moles/day, ESRD vs NLS, p>0.05). However, TMAO has a volume of distribution about one half that of urea. Also in NLS the urinary clearance of TMAO was high (219±78 ml/min) compared to the urinary urea and creatinine clearances (55±14 and 119±21 ml/min, respectively). Thus, TMAO levels achieve multiples of normal much greater than those of urea due mainly to 1) TMAO’s high clearance by the normal kidney relative to urea and 2) its smaller volume of distribution. Modelling suggests that only much more frequent dialysis would be required to lower levels Thus, additional strategies such as reducing production should be explored. Furthermore, using urea as the sole marker of dialysis adequacy may be misleading since a molecule, TMAO, that is dialyzed readily accumulates to much higher multiples of

    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

    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

    Cyanobacteria are commonly-occurring contaminants of surface waters worldwide. Microcystins, potent hepatotoxins, are among the best characterized cyanotoxins. During November, 2001, a group of 44 hemodialysis patients were exposed to microcystins via contaminated dialysate. Serum microcystin concentrations were quantified with enzyme-linked immunosorbent assay which measures free serum microcystin LR equivalents (ME). We describe serum ME concentrations and biochemical outcomes among a subset of patients during 8 weeks following exposure. Thirteen patients were included; 6 were males, patients’ median age was 45 years (range 16–80), one was seropositive for hepatitis B surface antigen. The median serum ME concentration was 0.33 ng/mL (range: <0.16–0.96). One hundred thirty nine blood samples were collected following exposure. Patients’ biochemical outcomes varied, but overall indicated a mixed liver injury. Linear regression evaluated each patient’s weekly mean biochemical outcome with their maximum serum ME concentration; a measure of the extrinsic pathway of clotting function, prothrombin time, was negatively and significantly associated with serum ME concentrations. This group of exposed patients’ biochemical outcomes display evidence of a mixed liver injury temporally associated with microcystin exposure. Interpretation of biochemical outcomes are complicated by the study population’s underlying chronic disease status. It is clear that dialysis patients are a distinct ‘at risk’ group for cyanotoxin exposures due to direct intravenous exposure to dialysate prepared from surface drinking water supplies. Careful monitoring and treatment of water supplies used to prepare dialysate is required to prevent future cyanotoxin exposure events. PMID:23894497

    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.

    Background: The endothelial progenitor cells (EPCs) dysfunction is a critical event in the initiation of atherosclerotic plaque development and the level of circulating EPCs can be considered a biomarker of cardiovascular events. The level and functional change in EPCs has been investigated in hemodialysis patients, but the effect of absolute number of EPCs on risk of death has not yet been explored. We hypothesized that the number of EPCs predicted death from cardiovascular and all-cause mortality in hemodialysis patients. Methods: We evaluate the association between endothelial progenitor cells and clinical outcome in 154 patients on maintenance hemodialysis. The blood sample was drawn at the time of patient enrollment and EPCs were identified by flow cytometry using triple staining for CD34/CD133/KDR. Results: The median duration of follow-up was 4.19 years. There were 79 (51.3%) deaths during the follow-up period, 41 of whom died due to a confirmed cardiovascular cause. The cumulative survival was greater in the high-EPC group than the low-EPC group for all-cause and cardiovascular mortality. Decreased EPCs levels were associated with a significant increase in the risk of cardiovascular and all-cause mortality after adjusting for age, gender, current smokers, diabetes mellitus, and hypertension. Conclusions: The level of circulating EPCs independently predicts the clinical outcome in patients on maintenance hemodialysis. Thus, the EPCs levels may be a useful predictive tool for evaluating the risk of death in maintenance hemodialysis patients. PMID:26941585

    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

    Background: Hemodialysis is the most common method of renal replacement therapy for treatment of acute and chronic kidney failure. Helicobacter pylori (H. pylori) plays a major role in development of peptic ulcer, gastric neoplasms, and lymphoma as well as increased risk of cardiovascular disorders in hemodialysis patients. Objectives: In this study the diagnostic values of noninvasive tests [i.e. urea breath test (UBT), helicobacter pylori stool antigen test (HPSA) and serology] in diagnosis of H. pylori infection in hemodialysis patients have been studied. Patients and Methods: All patients undergoing hemodialysis in Fatemieh Hospital, Semnan, Iran, were enrolled in the study, and their H. pylori status were assessed by using non-invasive tests including UBT, HPSA and serology. Patients with at least two out of 3 positive tests were considered infected with H. pylori. Results: The sensitivity, specificity, and positive and negative predictive values of the tests used in diagnosing H. pylori infection were 62.5%, 65.4%, 62.5% and 65.4% for UBT, 100%, 72.2%, 58.3% and 100% for serology, and 100%, 75%, 60.9% and 100% for fecal antigen test, respectively. Conclusions: This study showed that H. pylori serology and stool antigen tests have higher diagnostic values than UBT, and they are more reliable than UBT in diagnosis of H. pylori infection in hemodialysis patients.

    To explore detection and adequacy evaluation of erythrocyte glutathione S transferase (GST) on levels of circulating toxins in hemodialysis patients in Qinhuangdao region in China, this study divided 84 cases of long-term, end-stage hemodialysis patients into 2 groups: one group of 33 cases of adequate hemodialysis (spKt/V ≥ 1.3) and another group of 51 cases of inadequate hemodialysis (spKt/V < 1.3), according to the urea index value of the unit chamber model (spKt/V). Another 50 cases of subjects found healthy by a physical examination were taken as the control group, and the differences in the related clinical and biochemical indexes of the 3 groups were compared and analyzed. The levels of GST, creatinine, high sensitivity C-reactive protein (hs-CRP), transferrin saturation (TSAT), parathyroid hormone (PTH), interleukin-2,6,8 (IL-2,6,8) and tumor necrosis factor-a (TNF-a) in the hemodialysis group were significantly higher than those in the control group (P < 0.05), and GST, IL-2, 6, 8, and TNF-a levels in the inadequate hemodialysis group were significantly higher than in the adequate hemodialysis group (P < 0.05). Pearson's relevant analysis showed that the levels of GST and spKt/V, IL-2, IL-6, IL-8, and TNF-a have a positive correlation (P < 0.05), and they have no correlation with levels of creatinine, hs-CRP, TSAT, and PHT (P > 0.05). There were 23 patients with levels of spKt/V ≥ 1.3 after adjusting the dialysis solution for 51 cases of inadequate hemodialysis patients, and the GST level after the adjustment was significantly lower than that before the adjustment, but still higher than that in the adequate dialysis group. This concludes that the maintenance of hemodialysis in patients has certain relevance on spKt/V and associated inflammatory factors. Through the study, it can be determined that GST can effectively respond to adequate hemodialysis, which has a guiding significance on adjusting the blood dialysis solution in clinical practice.

    Introduction: Chronic renal failure exposes patients to the risk of several complications, which will affect every aspect of patient’s life, and eventually his hope. This study aims to determine the effect of stress management group training on hope in hemodialysis patients. Method: In this quasi-experimental single-blind study, 50 patients with renal failure undergoing hemodialysis at Motahari Hospital in Jahrom were randomly divided into stress management training and control groups. Sampling was purposive, and patients in stress management training group received 60-minute in-person training by the researcher (in groups of 5 to 8 patients) before dialysis, over 5 sessions, lasting 8 weeks, and a researcher-made training booklet was made available to them in the first session. Patients in the control group received routine training given to all patients in hemodialysis department. Patients’ hope was recorded before and after intervention. Data collection tools included demographic details form, checklist of problems of hemodialysis patients and Miller hope scale (MHS). Data were analyzed in SPSS-18, using Chi-square, one-way analysis of variance, and paired t-test. Results: Fifty patients were studied in two groups of 25 each. No significant difference was observed between the two groups in terms of age, gender, or hope before intervention. After 8 weeks of training, hope reduced from 95.92±12.63 to 91.16±11.06 (P=0.404) in the control group, and increased from 97.24±11.16 to 170.96±7.99 (P=0.001) in the stress management training group. Significant differences were observed between the two groups in hope scores after the intervention. Conclusion: Stress management training by nurses significantly increased hope in hemodialysis patients. This low cost intervention can be used to improve hope in hemodialysis patients. PMID:26925895

    This study set out to explore the experience of food cravings and thirst, and their management strategies in patients on hemodialysis. Semi-structured interviews with N = 32 hemodialysis patients were analyzed thematically. Findings indicated that food cravings and thirst were common in everyday life of patients and resulted in different emotional responses. A combination of cognitive and behavioral strategies was employed, including avoidance, controlled consumption, and substitution. Self-monitoring and compensatory strategies were also used to prevent or compensate for lapses. These findings lay the groundwork for future work aimed to improve adherence in end-stage renal disease patients. PMID:24659512

    Nontraumatic subarachnoid hemorrhage (SAH) in a dialysis patient is an uncommon occurrence and is often associated with high mortality. We report for the first time in India, a case of spontaneous nontraumatic, nonaneurysmal SAH without any cerebrovascular malformation in a maintenance hemodialysis patient, following a session of hemodialysis. The dialysis prescription needs to be modified in these patients, in order to prevent worsening of cerebral edema and progression of hemorrhage. Where available, continuous forms of renal replacement therapies, with regional anticoagulation seem to be the best option for such patients, till neurologic stabilization is achieved. PMID:26628800

    Quality of Life (QoL) is a consistent and powerful predictor that affects the out-come in end-stage renal disease (ESRD) patients on dialysis. This study was undertaken to identify the factors that might predict QoL scores among ESRD patients on hemodialysis (HD). The study was conducted at three HD units in Saudi Arabia from January 2007 to January 2008. We studied 100 HD patients (53 males and 47 females) and used the SF-36 and KDQoL-SF forms covering six domains of QoL, namely physical, emotional, social, illness impact, medical and financial satisfaction, and overall general health. The mean age of the study patients was 47.5 ± 13.8 years and the mean duration of dialysis was 77.2 ± 75.5 months. The QoL scores were 45.8 ± 17.1 for general health, 53.1 ± 32.0 for physical QoL, 50.5 ± 14.8 for emotional QoL, 54.9 ± 18.1 for social QoL, 46.5 ± 13.7 for illness impact, and 45.9 ± 12.2 for the medical and financial domain. The total QoL score was 49.5 ± 13.7. The male patients had statistically significantly reduced QoL and younger patients had better QoL scores. The QoL scores revealed a decreasing trend with decreasing level of education; they were elevated among employed patients. Multiple linear regression analysis demonstrated that age, dialysis duration, and male sex were negative predictors of QoL score. We conclude from our study that QoL is reduced in all the health domains of HD patients. Older age, male gender, unemployment, and duration of dialysis adversely affected the QoL scores. Adequate management of some of these factors could influence patient outcomes. PMID:23538347

    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. PMID:24619890

    Background Non-linear heart rate variability (HRV) indices were hypothesized to correlate with cardiac function, fluid overload and physical performance in hemodialysis patients Methods 24-hour Holter electrocardiograms were recorded in patients enrolled in the Frequent Hemodialysis Network (FHN) Daily Dialysis Trial. 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.

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

    Introduction The increase in the number of patients under hemodialysis treatment is a universal problem. With regard to the fact that there have been few social-psychological studies conducted on patients under hemodialysis treatment, the current study was conducted to investigate anxiety and perceived social support and the relation between them among these patients. Methods This cross-sectional study was conducted on 126 patients under hemodialysis treatment in Isfahan in 2012. After randomly selecting a hospital with a hemodialysis ward, purposive sampling was conducted. Data collection tools included state-trait anxiety and perceived social support inventory. The data were analyzed using the Spearman correlation coefficient. Results Among the participants, 68.3% received average perceived social support. In addition, perceiving the tangible dimension of support was lower compared to other dimensions (Mean 40.02). Level of trait and state anxiety (65 and 67.5%) of over half of the participants was average. There was in inverse relationship between state and trait anxiety and total perceived social support and emotional and information dimensions (r = −0.340, r = −0.229). State and trait anxiety had the highest relation with emotional and information dimension of social support, respectively. Conclusion Patients under hemodialysis treatment suffer from numerous psychological and social problems. Low awareness and emotional problems result in the increase of anxiety and reduction of perceived social support. Reduction of social support has negative effect on treatment outcomes. PMID:27148434

    The liver biopsy has long been the "gold standard" for assessing liver fibrosis in patients with hepatitis C. It's an invasive procedure which is associated with an elevated bleeding, especially in chronic hemodialysis patients. Main goal is to assess liver fibrosis in chronic hemodialysis with HCV by Fibroscan and by biological scores (APRI, Forns and Fib-4), and to measure the correlation between these tests. Cross-sectional study including all chronic hemodialysis patients with hepatitis C virus, in two public hemodialysis centers of Fez. All patients were evaluated for liver fibrosis using noninvasive methods (FibroScan and laboratory tests). Subsequently, the correlation between different tests has been measured. 95 chronic hemodialysis were studied, twenty nine patients (30.5%) with chronic hepatitis C. The average age was 52.38 ± 16.8 years. Nine liver fibrosis cases have been concluded by forns score. Fibroscan has objectified significant fibrosis in 6 cases. On the other side APRI has objectified sgnifivant fibrosis only in 3 cases. The Fib-4 showed severe fibrosis in five cases. The results have been most consistent between APRI and Fib-4, followed by Fibroscan and Forns, then APRI and FibroScan. PMID:26958136

    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

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

    2016-07-01

    The role of aldosterone has expanded from its genomic effects that involve renal sodium transport to nongenomic effects such as cardiac and renal fibrosis. Elevated aldosterone levels are associated with increased mortality in the general population. However, the association is reversed in patients with end-stage renal disease on maintenance hemodialysis. We have shown that the inverse association between aldosterone and mortality in hemodialysis patients is due to the confounding effect of volume overload. Volume overload, which is prevalent in patients with chronic kidney disease, is associated with both lower aldosterone concentrations and higher mortality. Our findings support salt and water restriction and treatment of hyperaldosteronemia in hemodialysis patients who have achieved strict volume control. PMID:26826322

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

    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

    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

    Context: Hypothyroidism is a common condition that disproportionately affects hemodialysis patients. In the general population, hypothyroidism is associated with higher mortality, particularly in populations with underlying cardiovascular risk. Despite their heightened cardiovascular mortality, the impact of hypothyroidism on the survival of hemodialysis patients remains uncertain. Objective: To examine whether hypothyroidism is independently associated with higher mortality in hemodialysis patients. Design, Setting, and Patients: Among 8840 incident hemodialysis patients receiving care from a large national dialysis provider from January 2007 to December 2011, we examined the association of hypothyroidism (TSH >5.0 mIU/L) with mortality. Main Outcome Measures: Associations between baseline and time-dependent hypothyroidism with all-cause mortality were determined using case-mix adjusted Cox models. In secondary analyses, we examined the impact of low-normal, upper-normal, subclinical range, and overt range TSH levels (TSH ≥0.5–3.0, >3.0–5.0, >5.0–10.0, and >10.0 mIU/L, respectively) on mortality risk. Results: The study population consisted of 1928 (22%) hypothyroid and 6912 (78%) euthyroid patients. Baseline and time-dependent hypothyroidism were associated with higher mortality: adjusted hazard ratios (95% confidence intervals) were 1.47 (1.34–1.61) and 1.62 (1.45–1.80), respectively. Compared to low-normal TSH, upper-normal, subclinical hypothyroid, and overt hypothyroid TSH levels were associated with incrementally higher adjusted death risk in baseline and time-dependent analyses. In time-dependent analyses, the hypothyroidism-mortality association was increasingly stronger across higher body mass index strata. Conclusions: Hypothyroidism as well as upper-normal TSH levels are associated with higher mortality in hemodialysis patients. Further studies are needed to determine whether restoration of TSH to low-normal levels with thyroid hormone

    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.

    Vaccine rates in patients on hemodialysis are substantially lower than the Healthy People 2020 targets. The purpose of this study is to utilize the perceptions and cues for action constructs of the Health Belief Model (HBM) to assess the attitudes of patients receiving outpatient hemodialysis regarding acceptance of the seasonal influenza, pneumococcal, and hepatitis B virus vaccines. Vaccine acceptance is defined as receiving the vaccine. Study findings suggest age, perceived susceptibility, and perceived severity increase the odds of getting some vaccines. Findings have implications for the development of patient education materials, interdisciplinary team assessments, and plan of care strategies to increase vaccine acceptance. PMID:25244894

    In hemodialysis patients, vascular access infection remains a significant cause of morbidity and mortality. It has various complications, including bacterial endocarditis, spinal epidural abscess, osteomyelitis, septic arthritis, and septic pulmonary emboli. However, aortitis with infected pseudoaneurysm formation is very rare. Here, we report a case of necrotizing aortitis in a hemodialysis patient with an arteriovenous graft infection. PMID:26042414

    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

    Background: Hypotension and muscular cramp are the common complications of hemodialysis. Effective control of hemodialysis complications increases the survival time and the quality of life of patients on hemodialysis. Considering that failure to follow a therapeutic plan is one of the most prevalent causes of hemodialysis complications, the present research was conducted to study the effect of two educational methods (family-centered and patient-centered) on some complications that occur during hemodialysis. Materials and Methods: This clinical trial was performed from June to November 2012 in the hemodialysis ward of Imam Khomeini Hospital and Tehran Amir Aalam Hospital. Research samples included 60 patients in the age range of 18-65 years who were randomly included in patient-centered education (30 people in even days) and family-centered education (30 people in odd days). Blood pressure and muscle cramp were checked using researcher-made checklist in three stages (before and at the second and fourth week after intervention). Hypotension (before the start of dialysis, at the first, second, and third hour, and at the end hours) and muscle cramp (in the middle of hemodialysis and the end half an hour) were also checked. Data were analyzed using SPSS software, version 16, with Chi-square test, Fisher test, and independent t-test. Results: Before intervention, the two groups did not show significant difference in terms of hypotension [with P = 0.91 and variations mean of 1.60 (1.30)] and muscle cramp [with P = 0.50 and variations mean of 1.06 (1.01)]. In the second and fourth week after intervention, there was significant difference between the two groups in terms of hypotension [with P = 0.016 and variations mean of 0.70 (0.70) and P = 0.02 and variations mean of 0.86 (0.62)] and muscle cramp [with P = 0.01 and variations mean of 0.46 (0.86) and P = 0.02 and variations mean of 1 (1.05)]. Conclusions: Considering that the study results showed that family

    Despite suggestions that higher serum magnesium (Mg) levels are associated with improved outcome, the association with mortality in European hemodialysis (HD) patients has only scarcely been investigated. Furthermore, data on the association between serum Mg and sudden death in this patient group is limited. Therefore, we evaluated Mg in a post-hoc analysis using pooled data from the CONvective TRAnsport STudy (CONTRAST, NCT00205556), a randomized controlled trial (RCT) evaluating the survival risk in dialysis patients on hemodiafiltration (HDF) compared to HD with a mean follow-up of 3.1 years. Serum Mg was measured at baseline and 6, 12, 24 and 36 months thereafter. Cox proportional hazards models, adjusted for confounders using inverse probability weighting, were used to estimate hazard ratios (HRs) of baseline serum Mg on all-cause mortality, cardiovascular mortality, non-cardiovascular mortality and sudden death. A generalized linear mixed model was used to investigate Mg levels over time. Out of 714 randomized patients, a representative subset of 365 (51%) were analyzed in the present study. For every increase in baseline serum Mg of 0.1 mmol/L, the HR for all-cause mortality was 0.85 (95% CI 0.77–94), the HR for cardiovascular mortality 0.73 (95% CI 0.62–0.85) and for sudden death 0.76 (95% CI 0.62–0.93). These findings did not alter after extensive correction for potential confounders, including treatment modality. Importantly, no interaction was found between serum phosphate and serum Mg. Baseline serum Mg was not related to non-cardiovascular mortality. Mg decreased slightly but statistically significant over time (Δ -0.011 mmol/L/year, 95% CI -0.017 to -0.009, p = 0.03). In short, serum Mg has a strong, independent association with all-cause mortality, cardiovascular mortality and sudden death in European HD patients. Serum Mg levels decrease slightly over time.

    2016-01-01

    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

    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.

    Background and objectives: Health-related quality of life (HRQOL) is a measure of the well being of hemodialysis patients and an independent prognostic predictor. Our aim was to determine whether HRQOL among hemodialysis patients has changed over time. Design, setting, participants, & measurements: We retrospectively analyzed data collected by Dialysis Clinic, Inc. from adult patients starting hemodialysis between January 1, 1997 and May 31, 2006. The primary outcome was HRQOL assessed by Short Form 36, 6 to 18 months after and closest to the 1-year anniversary of starting hemodialysis. Secular trends were analyzed by linear regression for continuous variables and logistic regression for categorical ones. Year of starting dialysis was the predictor. A five-point difference on a 0 to 100 scale was considered clinically significant. Results: Short Form 36 scores were available for 11,079 patients. Role Physical, General Health, Vitality, Social Functioning, and Physical Component Summary scores were unchanged among patients over the study period. Statistically significant (P < 0.05) but clinically insignificant changes were observed in Physical Functioning (−0.2 points/yr), Bodily Pain (+0.2 points/yr), Mental Health (+0.15 points/yr), and Mental Component Summary scores (+0.13 points/yr). Only Role Emotional showed clinically significant improvement. Trends were unchanged after adjusting for age, gender, race, diabetes, hemoglobin, phosphorous, Kt/V, and albumin. Conclusions: Most HRQOL domains showed either no statistically significant change or statistically but not clinically significant change over almost a decade. These results suggest that, despite important developments in hemodialysis care since 1997, little progress was made in improving HRQOL of hemodialysis patients. PMID:20019114

    We investigated the effects of frequency of hemodialysis on nutritional status by analyzing the data in the Frequent Hemodialysis Network Trial. We compared changes in albumin, body weight, and composition among 245 patients randomized to six or three times per week in-center hemodialysis (Daily Trial) and 87 patients randomized to six times per week nocturnal or three times per week conventional hemodialysis, performed largely at home (Nocturnal Trial). In the Daily Trial, there were no significant differences between groups in changes in serum albumin or the equilibrated protein catabolic rate by 12 months. There was a significant relative decrease in predialysis body weight of 1.5 ± 0.2 kg in the six times per week group at 1 month, but this significantly rebounded by 1.3 ± 0.5 kg over the remaining 11 months. Extracellular water (ECW) decreased in the six times per week compared with the three per week hemodialysis group. There were no significant between-group differences in phase angle, intracellular water, or body cell mass (BCM). In the Nocturnal Trial, there were no significant between-group differences in any study parameter. Any gain in 'dry' body weight corresponded to increased adiposity rather than muscle mass but was not statistically significant. Thus, frequent in-center hemodialysis reduced ECW but did not increase serum albumin or BCM while frequent nocturnal hemodialysis yielded no net effect on parameters of nutritional status or body composition.

    Introduction: Cardiovascular disease is the most common cause of morbidity and mortality in hemodialysis patients. Objectives: The aim of this study was to detect echocardiographic abnormality in the beginning and after 12-month follow-up in the hemodialysis patients. Patients and Methods: In a cross-sectional study, 60 hemodialysis patients older than 18 years and the dialysis duration longer than three months were enrolled. At the beginning of the study, echocardiography was done and after 12 months was repeated in all of the patients by the same cardiologist. At the end of the study, data were analyzed using SPSS software (version 19). Results: From the total of cases 37 were male and 23 female. At the beginning of the study, mitral regurgitation, tricuspid regurgitation and aortic insufficiency were found in 54, 47 and 11 patients respectively. After 12 months left ventricular ejection fraction (LVEF) decreased significantly, however there was no significant difference between other echocardiographic findings at the beginning and after 12 months. Conclusion: Decrease in LVEF over time in hemodialysis patients may be due to negative effect of uremia on cardiac function, so it seems that periodical cardiac evaluation of these patients is essential and beneficial.

    Arteriovenous fistulas are widely used for hemodialysis patients with end-stage renal failure. Due to the lack of suitable veins because of the arteriovenous fistulas previously opened in the upper extremity, alternative access routes are being tested. Few complications of long-term alternative arteriovenous fistulas have been reported in the literature. We report the results of surgical repairs of aneurysms that occurred on anterior tibial-saphenous arteriovenous fistulas (along the vein) in patients with end-stage renal disease after 5 years on hemodialysis.

    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

    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

    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

    Hemodialysis is not possible without access to the vascular system to provide an adequate and reliable source of blood flow through the hemodialyzer. Since maintenance hemodialysis therapy became a reality in the latter half of the twentieth century, no vascular access has exceeded the success and reliability of arteriovenous fistulae (AVF). They have the lowest infection and thrombosis rates, have the longest patency rates, and are associated with the best morbidity and mortality outcomes of any access modality. In the United States, the majority of patients starting hemodialysis do not have a primary AVF, which may explain why vascular access complications represent almost 20% of the total spending for hemodialysis. In addition, as much as 50% of hospitalization costs for end-stage renal disease are related to access issues. Every effort must be directed in the U.S. as well as elsewhere to promote the use of AVF whenever possible. In some European countries, more than 90% of patients have AVF as their hemodialysis access when nephrologists perform placement of vascular access. Already, some programs in the U.S. have recognized the need for trained nephrologists to provide these services. U.S. interventional nephrologists should be given the opportunity to learn AVF placement procedures to emulate their European counterparts, and thus improve U.S. dialysis outcomes. PMID:12662209

    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. PMID:24992542

    Background: Hemodialysis patients usually experience high levels of psychological stress, anxiety, and depression. Reducing these matters in patients provides more psychological resources to cope with their physical situation. Aim: The present study aimed to explore the efficacy of Benson's relaxation technique for stress, anxiety, and depression of patients with hemodialysis. Materials and Methods: Eighty hemodialysis patients were selected from two hospitals as an intervention and control groups. Then Benson relaxation training was implemented in the intervention group for 15 min twice a day during 4 weeks. The patients were assessed by depression, anxiety, and stress scale; which was completed before and after the intervention. Results: There were significant differences between stress and anxiety levels in case group before and after intervention (P > 0.001) and there is no meaningful difference between the mean of depression value in case group before and after intervention (P > 0.22). Conclusion: Instructing Benson's relaxation technique is accompanied by reducing stress and anxiety level of hemodialysis patients. Reducing stress and anxiety levels can provide more calmness for the patients so that pursuing medical therapy would be accompanied with more tranquility. Authors have suggested to improve and prevent the patients’ psychological problems as well as other chronic disorders by applying this practice. PMID:24251271

    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: 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

    Residual kidney function (RKF) may confer a variety of benefits to patients on maintenance dialysis. RKF provides continuous clearance of middle molecules and protein-bound solutes. Whereas the definition of RKF varies across studies, interdialytic urine volume may emerge as a pragmatic alternative to more cumbersome calculations. RKF preservation is associated with better patient outcomes including survival and quality of life and is a clinical parameter and research focus in peritoneal dialysis. We propose the following practical considerations to preserve RKF, especially in newly transitioned (incident) hemodialysis patients: (1) periodic monitoring of RKF in hemodialysis patients through urine volume and including residual urea clearance with dialysis adequacy and outcome markers such as anemia, fluid gains, minerals and electrolytes, nutritional, status and quality of life; (2) avoidance of nephrotoxic agents such as radiocontrast dye, nonsteroidal anti-inflammatory drugs, and aminoglycosides; (3) more rigorous hypertension control and minimizing intradialytic hypotensive episodes; (4) individualizing the initial dialysis prescription with consideration of an incremental/infrequent approach to hemodialysis initiation (e.g., twice weekly) or peritoneal dialysis; and (5) considering a lower protein diet, especially on nondialysis days. Because RKF appears to be associated with better patient outcomes, it requires more clinical and research focus in the care of hemodialysis and peritoneal dialysis patients. PMID:27182000

    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.

    The aim of this study was to evaluate the levels of malondialdehyde as an oxidative stress marker in the same hemodialysis patients after changing the quality of dialysate with ultrapure dialysis fluid. Methods. This prospective study concerns hemodialysis patients; all patients were in the first step treated with conventional dialysate, and in the second step (three months later) the same patients were treated with online produced ultrapure dialysis fluid. The malondialdehyde, C-reactive protein, total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, fibrinogen, and albumin were quantified before the two steps. Results. Thirty-seven patients completed the study. Ultrapure dialysis fluid reduced but not significantly the malondialdehyde concentrations. Both dialysis fluids were associated with improvement in the malondialdehyde level before and after the hemodialysis session. In lipid parameters, there was a significant decrease with conventional dialysis fluid versus ultrapure dialysis fluid of triglycerides, total cholesterol, and high-density lipoprotein in patients' blood. Instead, the level of low-density lipoprotein, fibrinogen, albumin, and C-reactive protein does not change significantly. Conclusion. The lipid parameters were improved for triglycerides and total cholesterol. Malondialdehyde increases following the hemodialysis session, and the conventional dialysate increased malondialdehyde levels more than the ultrapure dialysis but the differences were not statistically significant.

  8. What is the Role of HbA1c in Diabetic Hemodialysis Patients?

    PubMed

    Coelho, Silvia

    2016-01-01

    The definition of a good glycemic control in patients with diabetes mellitus on hemodialysis is far from settled. In the general population, hemoglobin A1c is highly correlated with the average glycemia of the last 8-12 weeks. However, in hemodialysis patients, the correlation of hbA1c with glycemia is weaker as it also reflects changes in hemoglobin characteristics and red blood cells half-life. As expected, studies show that the association between HbA1c and outcomes in these patients differ from the general population. Therefore, the value of HbA1c in the treatment of hemodialysis patients has been questioned. Guidelines are generally cautious in their recommendations about possible targets of HbA1c in this population. Indeed, the risk of not treating hyperglycemia should be weighed against the particularly high risk of precipitating hypoglycemia in dialysis patients. In this review, a critical analysis of the current role of HbA1c in the care of hemodialysis patients is presented. PMID:26138753

    Catheter-related blood stream infection (CRBSI) is a major complication in hemodialysis patients. We assessed the efficacy of systemic daptomycin (DPT) plus DPT antibiotic lock therapy (DPT-ALT) for catheter salvage in patients with Gram-positive CRBSIs. This is a retrospective study of hemodialysis patients with tunneled and cuffed hemodialysis catheters. All patients were from a single institution in Taipei and received systemic DPT plus DPT-ALT for the treatment of Gram-positive CRBSI. Successful resolution of CRBSI was implemented. Resolution of fever within 48 hours, negative result of repeated blood cultures after resolution of fever, no clinical evidence of CRBSI relapse and no need for catheter removal were measured. Fifteen hemodialysis patients received DPT-ALT for CRBSI, nine with coagulase-negative Staphylococcus (CONS), two with methicillin-resistant Staphylococcus aureus (MRSA), three with methicillin-sensitive Staphylococcus aureus (MSSA) and one with polymicrobial infections. Systemic DPT plus DPT-ALT cured 11 patients (73.3%). Treatment failed in all three MRSA cases (two with MRSA and one with MRSA + Enterococcus faecalis). Retrospective design and small sample size were the limitations of this study. Systemic DPT plus DPT-ALT appears to be a promising treatment for CRBSI from CONS and MSSA, but not for MRSA CRBSI. Systemic DPT plus DPT-ALT should be considered for patients with CRBSIs caused by certain species. PMID:26549513

    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.

    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.

    Installation of the Nephros Dual Stage Ultrafilter (DSU) added to a conventional hemodialysis unit to achieve ultrapure dialysate was tested in a group of 23 stable outpatients on chronic hemodialysis. Comparing the 6-month period prior to the installation of the filters (as baseline) to the 6-month period after the installation of the filters, we found a significant 40% reduction in the darbepoetin dose needed to maintain a stable hemoglobin level (p < 0.001). In addition, surrogate inflammatory markers, WBC count and serum albumin level, showed small but statistically significant improvements (p = 0.008 and p = 0.042, respectively). In conclusion, the use of the Nephros DSU to further reduce endotoxin exposure in chronic hemodialysis patients can result in improved erythropoiesis-stimulating agent (ESA) responsiveness and a lower ESA dose.

    Background One of the most prevalent problems in hemodialysis patients is sleep disturbance. Poor sleep quality has unpleasant bio-psycho-social outcomes. The positive effects of implementing the continuous care model (CCM) were verified with different variables, including sleep quality. This study was done with different populations, using two groups. Objectives This study aims to identify the sleep quality of hemodialysis patients in the city of Ilam and determine the effects of CCM on sleep quality. Patients and Methods We performed a quasi-experimental research study with 56 hemodialysis patients at the Shahid Mostafa Hospital in Ilam during 2014 and 2015. Pretests and posttests were conducted with the study groups and the control groups. Pretests were conducted over a one-month period, then repeated immediately before the study. Posttests were conducted immediately after the study and then repeated one month later. Participants were selected by census method and randomly divided into two groups. Ethical considerations were observed. Based on the continuous care model, interventions were performed through educational sessions over a three-week period. Consultations for continuous sleep monitoring, controls, and evaluations were conducted with the study group over the next nine weeks. Data were gathered from patient demographics questionnaires and PQSI, then introduced in SPSS 22 and analyzed with descriptive and analytic statistics (t-paired, ANOVA with repeated measures, follow-up tests such as S-N-K, Duncan, Sheffe and Tukey). Results One month prior to the study, 94.6% of the participants suffered from poor sleep quality. Immediately before and after the study, 91% complained of poor sleep quality. And one month after intervention, the figure dropped to 82%. Applying the CCM positively affected the sleep quality of hemodialysis patients in Ilam, and was statistically meaningful one month after intervention (P = 0.001).

    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

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

    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. PMID:25998500

    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. PMID:27067614

    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.

    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.

    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

    [Purpose] Increased plantar pressure during walking is a risk factor for foot ulcers because of reduced range of motion at the ankle and first metatarsophalangeal joints. However, the range of motion in patients undergoing hemodialysis has not yet been determined. A cross-sectional study was performed to investigate the factors affecting the range of motion of the ankle and first metatarsophalangeal joints in patients undergoing hemodialysis who walk daily. [Subjects and Methods] Seventy feet of 35 patients receiving hemodialysis therapy were examined. Measurements included the passive range of motion of plantar flexion and dorsiflexion of the ankle joint, and flexion and extension of the first metatarsophalangeal joint. [Results] Hemodialysis duration was not associated with ankle and first metatarsophalangeal joint range of motion in patients undergoing hemodialysis. Diabetes duration was significantly associated with limited ankle joint mobility. Finally, blood hemoglobin levels, body mass index, and age were associated with first metatarsophalangeal joint range of motion. [Conclusion] The present study identified age, diabetes, and decreased physical activity, but not hemodialysis duration, to be risk factors for limited joint mobility of the ankle and first metatarsophalangeal joints in patients undergoing hemodialysis.

    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/m(2)) 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

    The combination of daunorubicin and cytarabine is the cornerstone of induction therapy for acute myeloid leukemia (AML). Little data are available on the optimal chemotherapy regimen for patients with AML and advanced renal failure, with some authors recommending administration of reduced daunorubicin doses. We report the case of a 54-year-old AML patient on chronic hemodialysis who was treated with a modified induction regimen with reduced-dose daunorubin. Daunorubicin levels were measured during the treatment schedule. Although daunorubicin terminal t1/2 appears to be unaffected in hemodialysis patients, the estimated 0-23 h area under the curve was comparable with that of patients receiving full-dose daunorubicin. Therefore, dose adjustment in this patient group may be prudent. PMID:27254285

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

    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: Hepatitis C virus (HCV) infection is a significant health concern in patients with end-stage renal disease under dialysis. Epidemiological studies have reported a prevalence rate of 5.5-55.9% for this condition in Iran. Objectives: We evaluated the risk factors for HCV infection and seroconversion in hemodialysis patients. Patients and Methods: A retrospective analysis was performed on 455 hemodialysis patients from each of the five dialysis units in Tabriz, northwest Iran. Possible risk factors for HCV infection and seroconversion were evaluated. Results: A total of 37 patients were HCV positive (8.1% of the study population) and seroconversion occurred in 18 of them during the dialysis treatment (3.95% of the study population). History of renal transplantation (44.4%, P < 0.0001), surgical intervention (except for renal transplantation and AV fistula placement) (94.4%, P = 0.03), and mean duration of dialysis (106.06 ± 55.519, P < 0.0001) had strong statistically significant associations with the seroconversion. Conclusions: The current study indicates increased risk for HCV infection in patients under dialysis and its relation with the mean duration of hemodialysis, history of renal transplantation and surgical intervention. Considering the immune deficiency in these patients, intense education to both patients and medical staff will be beneficial. PMID:24976839

    Quantitative adjuvant zinc therapy using polaprezinc was performed to examine the correlation between zinc concentration and anemia in maintenance hemodialysis patients to propose appropriate treatment. Anemia and serum zinc concentration were measured in 117 patients with chronic renal failure receiving outpatient maintenance hemodialysis at Tsuyama Chuo Kinen Hospital. Two bags of polaprezinc (containing zinc 34 mg/day) were administered to 58 patients with lower than normal zinc levels (Zn < 80 mg/dl) as adjuvant zinc therapy to assess anemia improvement. Zinc concentration and all anemia parameters showed significant positive correlation, indicating that anemia improves in patients with high serum zinc levels. Regarding the effects of adjuvant zinc therapy for improving anemia, hemoglobin levels were found to increase significantly to the highest value at 3 weeks. During treatment, the dosage of erythropoietin was reduced significantly from baseline at all assessment points. No zinc poisoning from therapy was seen, but two patients had diarrhea (1.9%). Zinc-treated patients required iron therapy due to the development of iron deficiency. Most maintenance hemodialysis patients suffer from zinc deficiency anemia, and zinc-based polaprezinc has been confirmed to be an effective and safe adjuvant zinc treatment. Most patients diagnosed as refractory anemia with no response to erythropoietin also suffer from zinc deficiency anemia, many of whom are expected to benefit from zinc therapy to improve their anemia. Possible zinc deficiency anemia should be considered in the treatment of refractory anemia with no response to erythropoietin. PMID:19527468

    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

    Background: Sleep is one of the most fundamental human needs; without any doubt sleep is even more essential for sick patients, especially for patients with chronic illnesses. Sleep disturbance may lead to anxiety and reduced quality of life. Restless leg syndrome (RLS) is a sensory-motor disorder accompanied by a strong desire to move the legs or other parts of the body, which can cause sleep disturbance. Its etiology is unknown, but increased urea and creatinine levels before dialysis, iron deficiency due to kidney failure and end-stage renal disease (ESRD) are mentioned as causes. Objectives: This study is designed to examine the prevalence of insomnia and restless leg syndrome in patients undergoing chronic hemodialysis in Rafsanjan Ali Ibn Abitaleb Hospital. Patients and Methods: In this study we used two questionnaires to evaluate the presence of RLS and insomnia in ESRD patients who were undergoing hemodialysis treatment as kidney replacement therapy. Results: According to our results, 54.5% of patients were diagnosed with RLS, and of those 65.2% and 42.9% were women and men, respectively. RLS is seen more often among patients with blood group type A, but this result was not statistically significant. There was a statistically significant correlation between RLS and a positive family history of RLS, between RLS and the number of hemodialysis treatments per week and also between RLS and the Insomnia Severity Index. Unlike previous studies, in this study we did not find any statistically significant correlation between RLS and biochemical factors such as serum iron, TIBC, BUN, creatinine, potassium, calcium and phosphorous levels. Conclusions: The frequency of RLS among our patients was remarkable and we conclude that all patients who are undergoing hemodialysis should be screened for RLS, which can assist in providing proper attention and treatment.

    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.

    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.

    The incidence of cardiac death is higher among patients receiving dialysis compared with the general population. Although obstructive coronary artery disease is involved in cardiac deaths in the general population, deaths in hemodialysis patients occur in the apparent absence of obstructive coronary artery disease. To study this further, we prospectively enrolled 155 patients receiving hemodialysis after angiography had confirmed the absence of obstructive coronary lesions. All patients were examined by single-photon emission computed tomography using the iodinated fatty acid analog, BMIPP, the uptake of which was graded in 17 standard myocardial segments and assessed as summed scores. Insulin resistance was determined using the homeostasis model assessment index of insulin resistance (HOMA-IR). During a mean follow-up of 5.1 years, 42 patients died of cardiac events. Stepwise Cox hazard analysis associated cardiac death with reduced BMIPP uptake and increased insulin resistance. Patients were assigned to subgroups based on BMIPP summed scores and HOMA-IR cutoff values for cardiac death of 12 and 5.1, respectively, determined by receiver operating characteristic analysis. Cardiac death-free survival rates at 5 years were the lowest (32.2%) in the subgroup with both a summed score and assessment equal to or above the cutoff values compared with any other combination (52.9-98.7%) above, equal to, or below the thresholds. Thus, impaired myocardial fatty acid metabolism and insulin resistance may be associated with cardiac death among hemodialysis patients without obstructive coronary artery disease. PMID:20944544

    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.

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.

    Arsenic trioxide has been established for use in both relapsed and front-line treatment of acute promyelocytic leukemia. Dose adjustments are recommended to be considered in severe renal impairment although dosage reduction guidelines are not provided. In addition, toxicities of arsenic are significant. The use of arsenic trioxide has not been well studied in dialysis patients and there is a paucity of data in the literature to support the use in such a situation. We describe an 81-year-old relapsed acute promyelocytic leukemia hemodialysis-dependent patient with a pre-existing cardiac condition who was treated with 10 mg arsenic trioxide three times weekly after dialysis. These findings provide support along with the marginal amount of currently published data for an arsenic trioxide dosing regimen in hemodialysis patients. PMID:25972392

    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.

    Seasonal variation in blood pressure in patients undergoing hemodialysis in Europe has recently been described. If confirmed, this has important therapeutic, research, and epidemiological implications. All normotensive patients not administered antihypertensive drugs in our unit were studied. Predialysis blood pressures were measured before each dialysis treatment over two 2-month periods, January through February and July through August, in Winnipeg, Canada, a city with one of the most extreme seasonal temperature variations in North America. No difference in blood pressures was found between summer and winter (141 +/- 5/75 +/- 2 versus 140 +/- 4/74 +/- 2 mm Hg; P = not significant). Average daily temperatures were -16 degrees C in winter and 23 degrees C in summer. Interdialytic weight gain was the same in both groups. In conclusion, season has no effect on blood pressure in hemodialysis patients in a North American center. Reported seasonal changes in blood pressure in Europe may be related to nonclimatic factors.

    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.

    We report a case of testicular malignant lymphoma in a hemodialysis patient. A 65-year-old man who had been undergoing hemodialysis for 8 years and 10 months consulted our hospital with right testicular enlargement in August 2012. Under a diagnosis of testicular cancer from manipulation test and ultrasonography, high orchiectomy was performed. Computed tomography showed swelling of the retroperitoneal lymph nodes. Histopathological examination revealed diffuse, non-Hodgkin B-cell lymphoma, CD20+. R-CHOP chemotherapy was initiated and retroperitoneal lymph node swelling completely disappeared after 1 cycle of chemotherapy. After completing 2 cycles of chemotherapy, the patient developed interstitial pneumonia, and thus radiotherapy to the retroperitoneal space including the left testis was performed. As of July 2014, the patient remains alive without recurrence. PMID:25812596

    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

    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

    Immunologic complications of chronic renal failure are associated with the overproduction of proinflammatory cytokines by monocytes. This is partly due to renal failure itself but is further enhanced by hemodialysis treatment with frequent contact between blood and dialyzer membranes. Previous studies have shown an imbalance of proinflammatory and regulatory monokines in these patients. This study examines monokine production in hemodialysis patients using for the first time a very sensitive method of cytokine detection at a single-cell level by flow cytometry ("cytoflow technique"). Monocytes were stained intracellularly for the production of interleukin-6 (IL-6) and IL-10 after 20 h of culture with lipopolysaccharide. It was shown that high levels of proinflammatory IL-6 in hemodialysis patients are due to an increased number of monocytes producing this cytokine, while IL-6 synthesis per cell remains unchanged. In contrast, elevated levels of regulatory IL-10 are due to an increased synthesis per cell. This study demonstrates that in healthy subjects there is a population of monocytes producing exclusively IL-10 after 20 h of stimulation by lipopolysaccharide. This distinct population of regulatory monocytes is infrequent in dialysis patients, in whom most of the IL-10-positive monocytes also produce IL-6. These findings indicate that overproduction of proinflammatory factors in dialysis patients is at least in part due to a loss of cytokine-specific differentiation in monocytes. PMID:9727378

    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
