    This study sought to determine the prevalence of fibromyalgia syndrome and to identify whether fibromyalgia was associated with various clinical symptoms and laboratory parameters in hemodialysis patients. One hundred and forty-eight hemodialysis patients were examined for fibromyalgia symptoms according to the American College of Rheumatology criteria. Demographic characteristics, as well as causes of kidney failure, dialysis duration, and symptoms related to fibromyalgia were investigated. Of 148 patients, 18 (12.2%) were diagnosed with fibromyalgia. Patients with fibromyalgia had significantly poorer sleeping satisfaction than the control group (P = .02).The Beck Depression Inventory score was higher in 77.8% of the fibromyalgia patients than that in the control group (P = .006), but there was no significant difference in the anxiety score between the two groups (P = .86).In conclusion, there was a higher prevalence of fibromyalgia in hemodialysis patients than previously reported. Sleep disturbances and depression levels correlated with fibromyalgia.

    Full Text Available Introduction: Osteodystrophy is one of the long term complications of chronic renal failure and is expressed in two forms;low turn over and high turn over. It is an important cause of morbidity in patients with renal failure and if diagnosed and managed properly, many problems of these patients can be resolved. In this study we evaluated the prevalence of hyperparathyroidism in hemodialysis patients and its correlation with different factors. Methods: This study was an analytic, observational study that was done by the cross- sectional method. We formatted a questionnaire for hemodialysis patients who were enrolled in the study over a period of 6 months. Fasting blood samples (5-10c.c were drawn to measure levels of PTH(parathyroid hormone ,calcium, phosphorous and alkaline phosphatase. Skull and wrist X-rays were also taken and the radiologist evaluated them with regards to hyperparathyroidism. Results: In the 80 patients studied, prevalence of hyperparathyroidism was 45% (36 patients. 44 patients were diabetics. Among different factors, hyperparathyroidism did not correlate with frequency and duration of dialysis, age, sex ,familial history, diabetes, hypertension , bone pains, muscle weakness, purities and level of calcium and phosphorous. But there was a significant relationship between hyperparathyroidism and alkaline phosphatase levels and radiological findings. Conclusion: We can use alkaline phosphatase levels and/or radiographic changes for evaluation of renal osteodystrophy in hemodialysis patients and prevent complications by early diagnosis and proper management.

    Full Text Available OBJECTIVE: To assess the prevalence of malnutrition and associated factors in hemodialysis patients. METHODS: This is a cross-sectional study of 344 hemodialysis patients from Goiânia, Goiás aged 18 years or more. The dependent variable, malnutrition, was investigated by the Subjective Global Assessment. The independent variables included socioeconomic, demographic, and lifestyle data, clinical history, and energy and protein intakes. The patients underwent anthropometric measurements and laboratory tests. Multiple Poisson regression determined the associated factors (p60 months (PR=1.08, 95%CI=1.01-1.16, Kt/V>1.2 (RP=1.12, 95%CI=1.03-1.22, calorie intake <35 kcal/kg/day (PR=1.22, 95%CI=1.10-1.34, and normalized protein nitrogen appearance <1.0 g/kg/day (PR=1.13, 95%CI=1.05-1.21. CONCLUSION: The prevalence of malnutrition in this population was high, corroborating the literature. The prevalence was higher in patients aged less than 29 years and those with low family income, longer hemodialysis vintage, higher Kt/V, and inadequate protein and calorie intakes. Strategies to reverse this situation should include more nutritional care.

    Pulmonary hypertension (PH) is a progressive disorder that can be caused by several underlying conditions or an intrinsic alteration of the pulmonary vasculature. Chronic increased pressure in the pulmonary vasculature leads to changes in the architecture of the vessels that can perpetuate PH and produce right ventricular dysfunction. These structural and functional alterations can decrease survival and quality of life of patients on hemodialysis; however, there is a lack of evidence about this problem in this population. The aim of this study is to establish the prevalence of PH in patients on hemodialysis and its association with specific factors related to this patient population. We included 202 prevalent patients on hemodialysis for at least 6 months and who were clinically stable. We collected demographic data, routine laboratory parameters and data of 2D Doppler-echocardiography. PH was defined as a systolic pulmonary artery pressure (SPAP) estimated by Doppler ultrasound above 35mmHg. Hydration status was assessed by determining the plasma concentration of N-terminal pro brain natriuretic peptide (Nt-proBNP). PH prevalence was 37.1% (75 patients). The average SPAP in the entire study population was 32±12mmHg and in the group with PH it was 45±11mmHg. We found a direct and statistically significant correlation between the presence of PH and age (P=.001), time on renal replacement therapy (P=.04), the presence of systolic dysfunction (P=.007), diastolic dysfunction (P= 01), mitral valve disease (P=.01) and double mitral and aortic disease (P=.007). Volume overload was closely associated with PH, as demonstrated by the correlation between the SPAP and Nt-proBNP levels (P=.001). We conclude that prevalence of PH in hemodialysis patients is high. And one of the most important associated factors is volume overload. More studies are needed to establish the impact of PH on morbidity and mortality of patients and to assess whether a better volume control improves

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

    Full Text Available Purpose: The proposal of this study was to determine the prevalence and the associated factors of erectile dysfunction (ED among hemodialysis (HD patients. Materials and Methods: This was a cross-sectional study based on data collected from HD male patients. Clinical, demographic and laboratory data of all patients were collected in three HD clinics from December 2010 to June 2011. Patients answered questions of erectile function domain from International Index of Erectile Function. Data were evaluated by descriptive analysis and by univariate (ULRA and multivariate logistic regression analysis (MLRA. Results: Three hundred and five patients participated of the study. The prevalence of ED was 68.19%. ED was associated with diabetes (DM, benign prostatic hyperplasia, glomerulonephritis as cause of chronic renal failure (CRF, smoking habits, lower creatinine levels (ULRA, use of calcium channel blocker (MLRA, aging, lower education level, alcohol consumption, DM (as cause of CRF and coronary insufficiency (ULRA and MLRA. Conclusions: ED was highly prevalent in the HD men. It was independently associated with aging, current use of alcohol, long alcohol use (even for those who do not drink more, lower education level, diabetes as cause of CRF, coronary insufficiency and use of channel blockers calcium.

    Background The prevalence, determinants and prognosis of pulmonary hypertension among long-term hemodialysis patients in the USA are poorly understood. Methods A cross-sectional survey of prevalence and determinants of pulmonary hypertension was performed, followed by longitudinal follow-up for all-cause mortality. Pulmonary hypertension was defined as an estimated systolic pulmonary artery pressure of >35 mmHg using echocardiograms performed within an hour after the end of dialysis. Results Prevalent in 110/288 patients (38%), the independent determinants of pulmonary hypertension were the following: left atrial diameter (odds ratio 10.1 per cm/m2, P pulmonary hypertension (53%, CMR 168.9/1000 patient-years) and 39 among 178 without pulmonary hypertension (22%, CMR 52.5/1000 patient-years) [unadjusted hazard ratio (HR) for death 2.12 (95% confidence interval 1.41–3.19), P pulmonary hypertension remained an independent predictor for all-cause mortality [HR 2.17 (95% confidence interval 1.31–3.61), P pulmonary hypertension is common and is strongly associated with an enlarged left atrium and poor long-term survival. Reducing left atrial size such as through volume control may be an attractive target to improve pulmonary hypertension. Improving pulmonary hypertension in this group of patients may improve the dismal outcomes. PMID:22290987

    Full Text Available Malnutrition (MN in hemodialysis patients (HDP is prevalent worldwide. How-ever, data regarding the nutritional status among HDP living in Jeddah, Saudi Arabia, is lacking. The purpose of this study was to detect MN in HDP at the Jeddah Kidney Center, with an inexpensive nutritional assessment protocol consisting of anthropometric body mass index (BMI, triceps skin fold (TSF, mid-arm muscle circumference (MAMC and biochemical (albumin blood measurements and the seven-point subjective global assessment (SGA. A cross-sectional study assessed 269 HDP for MN through a questionnaire, SGA and anthropometric and biochemical measurements. Spearman′s rank correlation coefficients were determined between SGA and anthropometric and biochemical measurements as well as the relative odds of MN. Statistical significance was P <0.05. These HDP were 48.7% moderately and 6.3% severely malnourished. Albumin, BMI, TSF and MAMC correlated positively with the seven-point SGA (r s = 0.16, P = 0.007; r s = 0.33, P <0.001; r s = 0.29, P <0.001; and r s = 0.34, P <0.001, respectively. Those HDP who were female (Odds ratio [OR] = 2.04, P = 0.036, older (≥55 years (OR = 1.70, P = 0.087, uneducated (OR = 1.80, P = 0.072, with a lower BMI (<18 kg/m 2 (OR = 2.00, P = 0.077 and thinner TSF (OR = 1.45, P = 0.041 had a greater risk of MN. The high prevalence of MN was detected with an inexpensive protocol. Women with thinner TSF were more likely to be malnou-rished. The implementation of this protocol is warranted along with dietary education and counseling to decrease MN in HDP.

    Full Text Available Introduction and Objective: This study aimed at determining the prevalence of hepatitis C among 649 patients diagnosed with chronic or acute kidney disease − patients were undergoing hemodialysis treatment at a large hemodialysis center in Porto Alegre-RS, from January through December, 2012 –, as well as relating our data to that presented in the national census, reporting cases of coinfection by hepatitis C and human immunodeficiency virus (HIV, and defining the demographic profile of these patients. Method: An observational cross-sectional study was conducted and data was obtained from information in patients’ electronic medical records. Result and conclusion: The prevalence of hepatitis C in this study was 10.17% of the sampled population. However, further analysis of other liver centers would be required to estimate an accurate prevalence rate of infection caused by the hepatitis C virus in patients undergoing hemodialysis in Porto Alegre.

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

    Full Text Available BACKGROUNDS: This study was conducted to determine the prevalence and severity of anemia in children and adolescents on chronic hemodialysis, and to identify independent predictors of anemia in children on hemodialysis. METHODS: This cross-sectional study was performed between September 2005 and January 2006. The study population consisted of 25 patients aged 7−20 years on chronic hemodialysis from pediatric hemodialysis centers in Isfahan. RESULTS: A total of 22 (88% patients had hemoglobin levels of <11 g/dL (anemic and 12 patients (48% had hemoglobin levels of <8 g/dL (severe anemia. The mean age of these patients was 15.5 ± 3.7 years. Mean time on chronic dialysis was 20.44 ± 15.25 months. Anemia was more common and more severe among children who were on dialysis for less than 6 months. There was an inverse relationship between the severity of anemia and duration of hemodialysis (P = 0.019, r = – 0.465. Nearly all patients were treated with erythropoietin, Children with more severe anemia received slightly higher dose of erythropoietin (P = 0.09, r = 0.202. There was a significant difference between serum albumin values in anemic patients and patients without anemia (P = 0.023. There was a correlation between serum albumin and hemoglobin level (r = 0.511, P = 0.01. Intact PTH levels were >200 pg/ml in 16 patients (66% and >400 pg/ml in 9 patients (37. 5%. There was a reverse correlation between intact PTH level >200 pg/ml and hemoglobin level (r = -0.505, P = 0.046. CONCLUSIONS: The prevalence of anemia in hemodialysis children in Isfahan appears to be higher than that reported in the other studies in spite of extensive use of rHuEPO and iron supplementation. We found this to be especially true for patients new on hemodialysis (less than 6 months and in those with low albumin and severe hyperparathyroidism. KEY WORDS: Hemodialysis, anemia, children.

    Arteriovenous fistulas (AVFs) are the preferred form of hemodialysis vascular access, but maturation failures occur frequently, often resulting in prolonged catheter use. We sought to characterize AVF maturation in a national sample of prevalent hemodialysis patients in the United States. Nonconcurrent observational cohort study. Prevalent hemodialysis patients having had at least 1 new AVF placed during 2013, as identified using Medicare claims data in the US Renal Data System. Demographics, geographic location, dialysis vintage, comorbid conditions. Successful maturation following placement defined by subsequent use identified using monthly CROWNWeb data. AVF maturation rates were compared across strata of predictors. Patients were followed up until the earliest evidence of death, AVF maturation, or the end of 2014. In the study period, 45,087 new AVFs were placed in 39,820 prevalent hemodialysis patients. No evidence of use was identified for 36.2% of AVFs. Only 54.7% of AVFs were used within 4 months of placement, with maturation rates varying considerably across end-stage renal disease (ESRD) networks. Older age was associated with lower AVF maturation rates. Female sex, black race, some comorbid conditions (cardiovascular disease, peripheral artery disease, diabetes, needing assistance, or institutionalized status), dialysis vintage longer than 1 year, and catheter or arteriovenous graft use at ESRD incidence were also associated with lower rates of successful AVF maturation. In contrast, hypertension and prior AVF placement at ESRD incidence were associated with higher rates of successful AVF maturation. This study relies on administrative data, with monthly recording of access use. We identified numerous associations between AVF maturation and patient-level factors in a recent national sample of US hemodialysis patients. After accounting for these patient factors, we observed substantial differences in AVF maturation across some ESRD networks, indicating a

    Despite being frequently described, Restless Leg Syndrome (RLS) in patients, who are on hemodialysis, is a common disease which, has not been well documented in Iran. The current study aimed to investigate the prevalence of RLS and its sleep disorders in Iranian patients on hemodialysis. In this multicenter cross sectional study, 397 consecutive patients on hemodialysis were evaluated by face-to-face interviews. RLS was diagnosed using the International RLS Study Group (IRLSS) criteria. In addition, three validated sleep disorder questionnaires (Insomnia Severity Index, Epworth sleepiness scale and Pittsburgh sleep quality index) were completed by the patients. One hundred-twenty-six patients with RLS (31.7%; mean age 57.6 ± 15.4 years) participated in the current study. RLS mostly occurs in females (P quality of sleep (Pittsburgh Sleep Quality Index > 5, P = 0.001), higher scores of Epworth Sleepiness Scale (P caffeine, and other associated comorbidities between the patients with and without RLS. In the current study, prevalence of RLS was near the weighted-mean prevalence of other studies (mean 30%, range 8%t-52%). This is not just racial variability and may attribute to narrow or wide definition of the disease, plus variations of the prevalence recording time, and sometimes not using the standard criteria or standard interview.

    Anemia is a common complication of chronic kidney disease. We investigated the prevalence, characteristics and management of anemia in patients on chronic hemodialysis and assessed the response to blood-transfusion based management in Cameroon. This was a cohort study of five months' duration (August-December 2008) conducted at the Yaoundé General Hospital's hemodialysis center, involving 95 patients (67 men, 70.5%) on chronic hemodialysis by a native arteriovenous fistula. A monthly evaluation included full blood counts, number of pints of red cell concentrates transfused, and vital status. At baseline, 75 (79%) patients had anemia which was microcytic and hypochromic in 32 (43%). Anemia was corrected in 67 (70.5%) patients using blood transfusion only, while 28 (29.5%) patients were receiving erythropoietin (11 regularly, 39%). Only 77.2% of 342 pints (median 3.0, range 0-17 per patients) of red cell concentrates prescribed were effectively received during the follow-up at an unacceptably high cost to patients and families. Mean hemoglobin and mean corpuscular hemoglobin levels remained stable during follow-up, while mean corpuscular volume increased. Erythropoietin treatment was the main determinant of favorable trajectories of hematological markers. Patients on chronic hemodialysis have predominantly microcytic hypochromic anemia, with limited capacity for correction using blood transfusion.

    There are scarce epidemiological data on cardiovascular risk profile of chronic hemodialysis patients in Brazil. The CORDIAL study was designed to evaluate cardiovascular risk factors and follow up a hemodialysis population in a Brazilian metropolitan city. 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. 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). Hemodialysis patients in this southern metropolitan Brazilian city have a high prevalence of cardiovascular risk factors resembling many northern countries.

    2017-08-01

    Full Text Available This study aimed to determine the prevalence of infection related to the provisional catheter for hemodialysis in a teaching hospital and evaluate the risk factors associated with these infections.  A cross-sectional study analyzed by descriptive statistics and parametric tests. It was found that out of 129 patients, 48.8 % had catheter-related infection in hemodialysis, 65 % were male, 33.3 % were 60 years old and over, and 88 % of patients were admitted to intensive care unit. The prevalence of infection in this group was high, and the vast majority of diagnoses of infection were empirical. Given this, it is suggested to establish the routine culture of the catheter tip in all cases of suspected catheter infection to improve the quality of patient care, and the relentless pursuit of the causes that trigger the infection process in line with good practice from across the healthcare team.

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

    Full Text Available Hemodialysis patients are at high risk for hepatitis B virus (HBV infection. A survey was conducted in the hemodialysis population of the state of Goiás, Central Brazil, aiming to assess the prevalence of HBV infection, to analyse associated risk factors, and also to investigate HBV genotypes distribution. A total of 1095 patients were interviewed in 15 dialysis units. Serum samples were screened for HBV serological markers by enzyme-linked immunosorbent assay. Hepatitis B surface antigen (HBsAg positive samples were tested for HBV DNA by polymerase chain reaction and genotyped by restriction fragment length polymorphism. Global HBV infection prevalence was 29.8% (95% CI: 27.1-32.5. Multivariate analysis of risk factors showed that male gender, length of time on hemodialysis, and blood transfusion before 1993 were associated with HBV positivity. HBV DNA was detected in 65.4% (17/26 of the HBsAg-positive samples. Thirteen of 17 HBV DNA positive samples were genotyped. Genotype D (61.5% was predominant, followed by A (30.8%, while genotype F was detected in only one (7.7% sample.

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

    Detection of potential Fabry disease patients before appearance of life-threatening findings is of great importance, particularly in high-risk populations. This study was designed to determine prevalence of Fabry disease among Turkish patients undergoing peritoneal dialysis and hemodialysis for chronic renal failure (CRF). A total of 1,527 patients (mean (SD) age: 60.2 (14.2) years, 55.5% were males) on hemodialysis (n = 1,435) or peritoneal dialysis (n = 92) for CRF were included in this multicenter study conducted at 17 dialysis centers across Bursa province, Turkey. Prevalence of the disease was determined using combined enzymatic and genetic strategy with measuring the activity of α-galactosidase A (α-Gal A) and Sanger sequence analysis based genotyping in α-galactosidase A gene (GLA) in dried blood samples (DBS). Overall α-Gal A activity was determined to be below the reference value in 130 (8.5%) of 1,527 patients. GLA genotyping confirmed the diagnosis of Fabry disease in 5 (0.3%) patients with low α-Gal A activity. All Fabry-positive patients were males corresponding to a 0.6% prevalence of disease in this gender. In conclusion, our findings, which were based on the use of DBS for both enzymatic activity and genotyping analyses, revealed the diagnosis of Fabry disease in 5 males corresponding to overall 0.3% prevalence of disease in the cohort and 0.6% prevalence among males. Our results support the likelihood of unrecognized Fabry disease in a nonnegligible number of patients on dialysis and thus emphasize the value of screening studies in terms of detection of new cases and improved prognosis of the disease via early diagnosis and treatment.

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

    The influence of serum IL-6 levels on nutritional status in chronic hemodialysis (HD) patients remains to be elucidated. The present report describes a prospective longitudinal study of IL-6 levels and nutritional parameters to determine whether high IL-6 levels are independently associated with nutritional status over time in a cohort of prevalent hemodialysis patients. 85 clinically stable hemodialysis patients (37.6% women), with a mean age of 66.5 ± 10.6 years, were studied after exclusion of patients with BMI nutrition and body composition (anthropometry and bioimpedance analysis) were measured at baseline and at 6, 12, 18, and 24 months following enrollment. Observation of this cohort was continued over 2 additional years. IL-6 levels increased with time in both unadjusted (linear estimate: 2.57 ± 0.44 pg/ml per 2 yrs; P = 0.001) and adjusted models (linear estimate: 2.35 ± 0.57 pg/ml per 2 yrs; P = 0.049). Significant reductions of daily energy intake, laboratory markers (albumin, transferrin, cholesterol, creatinine), and body composition (fat mass) with higher IL-6 levels were observed over the duration of the longitudinal observation period. However, none of the studied parameters were associated with changes in IL-6 levels over time (IL-6-by-time interactions were NS). Furthermore, cumulative incidences of survival were correlated with the baseline serum IL-6 levels (P = 0.004 by log-rank test). Finally, for each pg/ml increase in IL-6 level, the hazard ratio for death from all causes was 1.06 (95% CI 1.01 to 1.10) after adjustment for demographic and clinical parameters. Our results suggest that higher serum IL-6 levels are associated with all-cause mortality without additional changes in clinical and laboratory markers of nutritional status in clinically stable HD patients.

    Hepatitis C virus (HCV) is one of the most common infections among hemodialysis (HD) patients. It continues to be exasperating problem in many HD centers, in spite of strictly following infection and quality control measures. This is a multi-center retrospective comparative study, carried out in different HD units of Menoufia Governorate, Egypt. Patients who were HCV negative on starting HD were divided into two groups; Group-1 included patients who remained negative for HCV and group-2 included patients who seroconverted to HCV positive status during dialysis. Risk factors for seroconversion were compared between the two groups. Out of the 514 surveyed patients, 259 were negative for HCV and 255 were positive; the prevalence of HCV infection was 49.6%. A total of 303 patients who were HCV negative on starting HD were recruited in the study. Group-1 included 259 patients who remained negative for HCV and group-2 included the 44 patients who seroconverted to HCV positive status during dialysis. Patients in group-2 had significantly longer duration on dialysis compared to group-1 (71 .4 versus 33.7 months) and they had stronger family history of HCV infection (20.5% versus 6.4%). There is high prevalence and high seroconversion rate of HCV in surveyed HD units. Following infection control measures and strict supervision of dialysis staff should be emphasized. More studies are needed to evaluate the possible benefits of isolation protocols of HCV patients on regular HD.

It is a cross-sectional prospective study conducted at Hemodialysis unit of Shalamar Hospital and Shaikh Zayed Hospital, Lahore from 1/sup st/ January 2006 to 30/sup th/ April 2006. All patients getting regular hemodialysis for more than three months were included. Beck's Depression Inventory- II (BDI-II; adapted in Urdu) was administered on all the patients who were able to read or understand it. Blood sample were drawn at the same time for routine hematological, biochemical parameters and viral markers (Anti HCV and HbsAg). Diagnosis was made as per Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM IV) for correlation of psychological variables with clinical, hematological and biochemical parameters. Eighty nine patients were enrolled which included fifty two (58.4%) were male and seventy seven (86.5%) were married. Major causes of renal failure were diabetes, hypertension and chronic glomerulonephrotis. Duration of dialysis was from 03 to 49 months with mean of 19.64 +- 11.7 months. Severity of depression was categorized in to mild, moderate and severe on the basis of BDI score. Majority of the patients fifty (56.1%) were moderately to severely depressed and there was no gender difference in the prevalence of depression. Majority of patients undergoing hemodialysis were depressed. Major risk factors for depression were marital status, illiteracy, number of children, socioeconomic factors, gender, hypertension and hypoalbuminemia. Patients with anemia, hyponatremia and hyperkalemia had suicidal tendency. Patients with hepatitis C and disturbed liver function have strong correlation with psychological parameters. (author)

    Mounting evidence indicates an increased risk of cognitive impairment in adults with end-stage kidney disease on dialysis, but the extent and pattern of deficits across the spectrum of cognitive domains are uncertain. We conducted a cross-sectional study of 676 adult hemodialysis patients from 20 centers in Italy, aiming to evaluate the prevalence and patterns of cognitive impairment across five domains of learning and memory, complex attention, executive function, language and perceptual-motor function. We assessed cognitive function using a neuropsychological battery of 10 tests and calculated test and domain z-scores using population norms (age or age/education). We defined cognitive impairment as a z-score  ≤ -1.5. Participants' median age was 70.9 years (range 21.6-94.1) and 262 (38.8%) were women. Proportions of impairment on each domain were as follows: perceptual-motor function 31.5% (150/476), language 41.2% (273/662), executive function 41.7% (281/674), learning and memory 42.2% (269/638), complex attention 48.8% (329/674). Among 474 participants with data for all domains, only 28.9% (n  =  137) were not impaired on any domain, with 25.9% impaired on a single domain (n  =  123), 17.3% on two (n  =  82), 13.9% on three (n  =  66), 9.1% on four (n  =  43) and 4.9% (n  =  23) on all five. Across patients, patterns of impairment combinations were diverse. In conclusion, cognitive impairment is extremely common in hemodialysis patients, across numerous domains, and patients often experience multiple deficits simultaneously. Clinical care should be tailored to meet the needs of patients with different types of cognitive impairment and future research should focus on identifying risk factors for cognitive decline.

    Full Text Available Transfusion-transmitted virus (TTV is a single-stranded DNA virus that was identified in patients with post-transfusion hepatitis of non-A-to-G type. Patients with chronic renal failure on maintenance hemodialysis (HD have a higher risk of viral infections, and the prevalence of TTV infection is common. The aim of our study was to detect TTV-DNA and its genotype in HD patients. A case-control study compromising of 63 patients on maintenance HD therapy at the Nephrology Center of Central Arar Hospital and 100 healthy individuals who were tested for TTVDNA and its genotype by semi nested-polymerase chain reaction with primers derived from the conserved open reading frame 1 (ORF1 region followed by digestion with NdeI and PstI restriction enzyme. The results show that the prevalence of TTV in HD patients was high and statistically significant; 42.9% compared with 19% in the control group. History of blood transfusion was the only significant predictor, and we found that age of patients, duration of HD, hepatitis B and C infection, aspartate aminotransferase and alanine aminotransferase levels were not significant predictors of TT virus positivity in HD patients. TTV genotype 1 (G1 was found to be the most common genotype among both HD and healthy controls. The prevalence of TTV among HD patients was significantly higher than that in healthy individuals. History of blood transfusion was the only significant predictor of TTV positivity among them. Genotype 1 was the most predominant type among HD and healthy individuals. Further studies on TTV in peritoneal dialysis patients and transplant patients are needed.

    Hepatitis C (HCV) is a serious public health issue, and it is estimated that 3% of the world's population is infected. Patients in hemodialysis units have an increased risk for contracting HCV, and high prevalence rates have been found in hemodialysis units around the world. This study is aimed at determining the prevalence of HCV in patients with terminal chronic renal disease (tCRD) who have been submitted to hemodialysis and peritoneal dialysis in southern Brazil to characterize the most prevalent genotypes, the viral load, and possible risk factors and to assess the validity between the ELISA and RT-PCR detection methods. Of 320 patients from three dialysis units, 318 participated in this study. According to the medical records, 55 patients were reactive to HCV, as determined via ELISA. All 318 samples were submitted to RT-PCR and genotyped using an Abbott Realtime m2000 system. Data obtained through a questionnaire and chemical variables were associated with the HCV. The prevalence of HCV was 18.24% (58), and the concordance between the HCV serology and the RT-PCR was 94%. Three patients were diagnosed to be negative for HCV using the ELISA assay but positive when using RT-PCR. Genotype 1 was the most prevalent (46.7%) genotype, within which subtype 1a was the most frequent (74.1%). One of the risk factors associated with HCV infection was the length of time that the patient had been undergoing hemodialysis treatments (p HCV in dialysis units continues to remain high, indicating nosocomial contamination. RT-PCR detected the presence of the hepatitis C virus in patients with a non-reactive serology, which highlights the importance of performing molecular tests on dialysis patients. The variation in the viral load in patients submitted to hemodialysis indicates a possible destruction or gripping of viral particles to the dialyzer membrane.

The aim of this study was to systematically review available evidence on the prevalence and severity of pain in adult end-stage renal disease patients on chronic intermittent HD. Materials and methods: We carried out a systematic review of the literature and developed a comprehensive search strategy based on search terms on pain and HD. We searched the databases MEDLINE, Scopus, PsycINFO, and CINAHL from the earliest date of each database to July 24, 2014. Manuscripts in all languages were taken into consideration. Two authors performed each step independently, and all disagreements were resolved after discussion with the third author. The quality of studies was estimated using the STROBE checklist and Cochrane risk-of-bias tool.Results: We included 52 studies with 6,917 participants. The prevalence of acute and chronic pain in HD patients was up to 82% and 92%, respectively. A considerable number of patients suffered from severe pain. Various locations and causes of pain were described, with most of the studies reporting pain in general, pain related to arteriovenous access, headache, and musculoskeletal pain.Conclusion: The findings of this systematic review indicate high prevalence of pain in HD patients and considerable gaps and limitations in the available evidence. Pain in this population should be recognized as a considerable health concern, and the nephrology community should promote pain management in HD patients as a clinical and research priority to improve patients’ quality of life and pain

    This study was designed to determine the prevalence of protein-energy wasting (PEW) and its various types in hemodialysis (HD) patients in Tehran, Iran. For this cross-sectional study, 291 HD patients were randomly selected. The nutritional status of the patients was determined by subjective global assessment (SGA) and their dietary intakes were assessed using a 4-day dietary recall. In addition, serum high-sensitive C-reactive protein (hs-CRP) was measured. The prevalence of mild-to-moderate and severe PEW based on SGA was 60.5% and 1% in Tehran HD patients, respectively. The prevalence of various types of PEW in HD patients was 20.5% type I (inadequate energy or protein intake without inflammation), 65.5% type IIa (inadequate energy or protein intake with inflammation), and 14% type IIb (adequate energy and protein intake with inflammation). Of the total HD patients with no PEW based on SGA, about 3.5% had type 0 normal nutritional status (adequate energy and protein intake without inflammation), 34% had type I normal nutritional status (inadequate energy or protein intake without inflammation), 55.5% had type IIa normal nutritional status (inadequate energy or protein intake with inflammation), and 7% had type IIb normal nutritional status (adequate energy and protein intake with inflammation). PEW in Tehran HD patients is considerably prevalent and PEW type IIa is the most common type. In addition, HD patients with no PEW based on SGA should also be paid attention because they may be in the early stages of inadequate intake of energy and/or protein and inflammation.

    Full Text Available An hemodialysis population in Central Brazil was screened by polymerase chain reaction (PCR and serological methods to assess the prevalence of hepatitis C virus (HCV infection and to investigate associated risk factors. All hemodialysis patients (n=428 were interviewed in eight dialysis units in Goiânia city. Blood samples were collected and serum samples screened for anti-HCV antibodies by an enzyme-linked immunosorbent assay (ELISA. Positive samples were retested for confirmation with a line immunoassay (LIA. All samples were also tested for HCV RNA by the PCR. An overall prevalence of 46.7% (CI 95%: 42-51.5 was found, ranging from 20.7% (CI 95%: 8.8-38.1 to 90.4% (CI 95%: 79.9-96.4 depending on the dialysis unit. Of the 428 patients, 185 were found to be seropositive by ELISA, and 167 were confirmed positive by LIA, resulting in an anti-HCV prevalence of 39%. A total of 131 patients were HCV RNA-positive. HCV viremia was present in 63.5% of the anti-HCV-positive patients and in 10.3% of the anti-HCV-negative patients. Univariate analysis of risk factors showed that the number of previous blood transfusions, transfusion of blood before mandatory screening for anti-HCV, length of time on hemodialysis, and treatment in multiple units were associated with HCV positivity. However, multivariate analysis revealed that blood transfusion before screening for anti-HCV and length of time on hemodialysis were significantly associated with HCV infection in this population. These data suggest that nosocomial transmission may play a role in the spread of HCV in the dialysis units studied. In addition to anti-HCV screening, HCV RNA detection is necessary for the diagnosis of HCV infection in hemodialysis patients.

Here, we investigated the prevalence of GERD symptoms and the effects of the PPI esomeprazole on the quality of life related to reflux and dyspepsia in patients on maintenance hemodialysis. This was a cross-sectional/cohort study of hemodialysis outpatients implemented in 10 Japanese medical facilities from October 2012 to March 2014. The trial was registered in the UMIN Clinical Trial Registry (UMIN000009124). Forty-one of 385 patients (11%) reported GERD symptoms on the Global Overall Symptom (GOS) questionnaire. Multivariate logistic regression analysis identified the independent prognostic factors for GERD symptoms as a history of gastric ulcer and use of sevelamer hydrochloride or calcium polystyrene sulfonate. Participants with GERD symptoms completed the Quality of Life in Reflux and Dyspepsia, Japanese version (QOLRAD-J) questionnaire and were assigned to receive 4-week esomeprazole treatment (20 mg/day). This PPI therapy significantly improved all QOLRAD-J domains in the full analysis set (n = 28) and improved the GERD symptoms listed in the GOS questionnaire. Significantly impaired disease-specific quality of life (QOL) in the QOLRAD-J domains was observed in 44.4-74.1% of patients who had symptoms before treatment. The mean GOS and QOLRAD-J scores correlated significantly. Therapy with 20 mg/day esomeprazole appears to be efficacious for improving disease-specific QOL and GERD symptoms in Japanese patients on maintenance hemodialysis.

No prospective evaluation of the prevalence or clinical significance of PH in chronic dialysis patients in the United States (US has been undertaken.Methods: Echocardiograms were performed prospectively in chronic hemodialysis patients prior to dialysis at a single dialysis center. PH was defined as a tricuspid regurgitant jet ≥2.5 m/s and “more severe PH” as ≥3.0 m/s. Clinical outcomes recovered were all-cause hospitalizations and death at 12 months.Results: In a cohort of 90 patients, 42 patients (47% met the definition of PH. Of those, 18 patients (20% met the definition of more severe PH. At 12 months, mortality was significantly higher in patients with PH (26% compared with patients without PH (6%. All-cause hospitalizations were similar in patients with PH and without PH. Echocardiographic findings suggesting impaired left ventricular function and elevated pulmonary capillary wedge pressure were significantly associated with PH.Conclusion: This prospective cross-sectional study of a single dialysis unit suggests that PH may be present in nearly half of US dialysis patients and when present is associated with increased mortality. Echocardiographic findings demonstrate an association between elevated filling pressures, elevated pulmonary artery pressures, and higher mortality, suggesting that the PH may be secondary to diastolic dysfunction and compounded by volume overload.Keywords: renal failure, pulmonary hypertension, diastolic dysfunction

    Vitamin D is claimed to have an adjuvant effect on glycemic control by dual action on pancreatic β-cells and insulin resistance. The aim of this study was to assess the possible effect of short-term alfacalcidol supply on glycemic control in type 2 diabetic hemodialysis (HD) patients. Twenty type 2 diabetic HD patients (using diet and oral drugs but not insulin) were randomly selected from our dialysis unit as well as 20 non-diabetic HD patients as control. A third group of 12 healthy subjects were studied as well. All three groups were similar in age, sex, and body mass index. Oral alfacalcidol therapy was administrated daily as recommended by Kidney Disease Outcomes Quality Initiative (K/DOQI) guidelines for 12 weeks guided by monthly serum phosphorus and Cax PO4 product. Corrected total calcium, phosphorus, intact parathyroid hormone, 25-hydroxy vitamin D (25[OH]D), and glucoparameters (fasting blood glucose, glycated hemoglobin [HbA1c%], insulin resistance by homeostatic model assessment, and β-cell function by HOMA-β%) were measured under basal conditions and after 3 months of therapy. 25(OH)D was non-significantly lower in diabetic than non-diabetic HD patients, but significantly lower than healthy subjects at the start of the study. However, vitamin D level increased significantly after 3 months of trial, although the levels did not reach normal values. This vitamin D rise was associated with highly significant improvement in concentrations of fasting blood sugar (FBS), fasting insulin, HbA1c%, and HOMA-β-cell function in diabetic and non-diabetic controls. However, there was a significant rise in insulin resistance after treatment. The percentage of change was evident more in diabetics regarding FBS and 25(OH)D concentration. Adjustment of 25(OH)D level in type 2 diabetic prevalent HD patients may improve, at least with short-term therapy, glycemic control mainly through improving β-cell function. © 2015 International Society for Hemodialysis.

    Full Text Available Introduction. The pathogenicity and transmission routes of Transfusion Transmitted Virus (TTV remain unclear. The aim of this study was to determine the prevalence of TTV in hemodialysis patients, injecting drug users (IDUs, and healthy blood donors, in Isfahan, Iran. Method. In a case-control study, a total of 108 subjects were put into three groups namely Group I, 36 hemodialysis patients; Group II, 36 IDUs; and Group III, 36 healthy blood donors as the control group. A 5 ml blood sample was collected from each subject in an EDTA-containing tube. Samples were tested for TTV DNA by means of real-time polymerase chain reaction (PCR. Results. The mean age was years. Seventy-one subjects (66% were male. Of the108 cases, 30 (27.8% were TTV positive and 78 (72.2% were TTV negative. The prevalence of TTV in IDUs [21 (58%] was significantly higher than in the other groups [group I: 6 (17 % and group III: 3 (8%] (. Conclusion. The prevalence of TTV in IDUs is significantly higher than in both hemodialysis patients and general population in Isfahan, Iran. It seems necessary to take serious measures to reduce the risk of TTV transmission to IDUs’ close contacts and health care providers.

The aim of this study was to investigate the prevalence of AF in a population-based cohort of HD patients and practice patterns of antithrombotic therapy for stroke prevention in AF.The Vienna InVestigation of AtriaL fibrillation and thromboembolism in patients on hemodialysis (VIVALDI, an ongoing prospective observational cohort study, investigates the prevalence of AF and the risk of thromboembolic events in HD patients in Vienna, Austria. We analyzed cross-sectional data of 626 patients (63.4% men, median age 66 years, approx. 73% of HD patients in Vienna, who provided informed consent. A structured interview with each patient was performed, recent and archived ECGs were viewed and medical histories were verified with electronic records.The overall prevalence of AF was 26.5% (166 patients, 71.1% men, median age 72 years of which 57.8% had paroxysmal AF, 3.0% persistent AF, 32.5% permanent AF, and 6.6% of patients had newly diagnosed AF. The median CHA2DS2-VASc Score was 4 [25th-75th percentile 3-5].

    A serologic study of Chagas disease was performed in 110 patients submitted to chronic hemodialisis and blood transfusions. Immunofluorescence antibody testing (IgG and IgM) was positive in 6 out of 62 patients receiving multiple blood transfusions (9.7%), but negative in all 48 subjects without transfusions. Thus, repeated blood transfusion is a significant risk for T cruzi infection in chronic hemodialized patients.

    Infections continue to be a major cause of morbidity and mortality in patients with end-stage renal disease. While rates of all-cause hospitalization of prevalent end-stage renal disease patients receiving hemodialysis reported by the United States Renal Data System fell from 1993 to 2007, rates of hospitalization for infections rose by 26%. Developing a better understanding of the reasons for this rise and employing strategies to reverse it have become a priority for patients, providers and regulatory agencies in the USA. In addition, recent episodes of transmission of bloodborne hepatitis viruses in outpatient healthcare facilities, including hemodialysis centers, related to suboptimal infection control and injection safety practices, have raised concerns about patient safety. In this article, we review many of the current infection control challenges facing outpatient dialysis centers and discuss recommended infection control policies and practices aimed at combating these challenges.

    Full Text Available 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.

The data from 219 patients and their records over the period between 2000-2013, was extracted and analyzed. The mean ± SD age of the patients was 47.08 ± 13.9 years; 74.4% of them were married and 14.6% were employed. The prevalence of validated anti-HCV-positive cases was 40.2% (95%CI 33.64%-46.73%). The mean ± SD duration on HD of all the patients was 35.09 ± 38 months. On bivariate analysis, the duration on HD and attending more than one center for HD associated significantly with anti-HCV positivity (P <0.05). On multivariate fully adjusted Poisson regression modelling, controlled for age, Patients attending more than one center and those who underwent HD for longer durations were more likely to be positive for anti- HCV antibodies [P = 0.004, adjusted prevalence rate ratio (APRR) = 1.87, 95% confidence interval (CI): 1.22-2.88; P = 0.0005, APRR = 1.01, 95% CI: 1.00-1.02. In this study sample, the prevalence of HCV was significant. Patients attending more than one center and those who underwent HD for longer durations were found to be more likely to contract HCV. Enhancing existing infection control measures and allocating more resources to HD centers therefore warrants consideration.

    Hepatitis B virus (HBV), hepatitis D virus (HDV), and human immunodeficiency virus (HIV) are transmitted by blood transfusion. Thus, hemodialysis (HD) patients are more prone to become the carriers of these infections due to their treatment demands. The aim of this study was to assess the prevalence of HBV and HIV infections among HD patients in Bandar Abbas, Iran, 2015. A total of 153 patients with chronic renal failure undergoing HD at Shahid Mohammadi hospital in Bandar Abbas were examined for hepatitis B surface antigen (HBsAg), anti- hepatitis C virus, and anti-HIV over a period of 2 months. Thereafter, all of the specimens were evaluated for HBV-DNA, HDV-RNA and HIV-RNA using polymerase chain reaction (PCR) and further techniques. All statistical analyses were carried out using SPSS version 12 for Windows with the t-test and chi-square (χ(2)) test. Both kinds of assay determined that nine (5.88%) patients were HBV positive (HBsAg-positive), whereas no HIV- and HDV-positive patients were diagnosed. All of the diagnosed HBV samples belonged to genotype D; the prevalence of HBV is associated with age, duration of HD, history of blood transfusion, and using shared HD devices. In conclusion, the prevalence of HBV infection was low in the south of Iran, but genotype D represented the major HBV genotype in this population. Among the variables, age, duration of HD, history of blood transfusion, and using shared HD devices influenced the prevalence of HBV among HD patients.

    Full Text Available 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.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.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.Plasma copeptin levels are elevated predialysis and increase further during hemodialysis.

    Amyloidosis in long-term haemodialysis patients mainly involves the osteo-articular system. It is held responsible for carpal tunnel syndrome, chronic arthralgia and various types of arthropathy, chronic synovitis and tenosynovitis, haemarthrosis, subacute polyarthritis and destructive arthropathies of the limbs and spine. Radiologically, amyloidosis may appear as bone cavities, particularly visible in the hips and wrists. Its frequency increases with the duration of haemodialysis. Biochemically, amyloidosis consists of beta 2-microglobulin (beta 2-M). This protein accumulates in uraemic patients under dialysis and seems to play a major role in the pathogenesis of amyloid deposits. The accumulation is due to renal impairment, being maximum in anuric patients. However, the unsatisfactory clearance of beta 2-M by dialysis methods also contributes to its retention: the production and elimination of beta 2-M seems to vary according to the extrarenal clearing technique. These data suggest that improvements in clearing techniques will eventually prevent dialysis amyloidosis.

    Full Text Available Abstract Background The influence of serum leptin levels on nutritional status and survival in chronic hemodialysis patients remained to be elucidated. We conducted a prospective longitudinal study of leptin levels and nutritional parameters to determine whether changes of serum leptin levels modify nutritional status and survival in a cohort of prevalent hemodialysis patients. Methods Leptin, dietary energy and protein intake, biochemical markers of nutrition and body composition (anthropometry and bioimpedance analysis were measured at baseline and at 6, 12, 18 and 24 months following enrollment, in 101 prevalent hemodialysis patients (37% women with a mean age of 64.6 ± 11.5 years. Observation of this cohort was continued over 2 additional years. Changes in repeated measures were evaluated, with adjustment for baseline differences in demographic and clinical parameters. Results Significant reduction of leptin levels with time were observed (linear estimate: -2.5010 ± 0.57 ng/ml/2y; p Conclusions Thus leptin levels reflect fat mass depots, rather than independently contributing to uremic anorexia or modifying nutritional status and/or survival in chronic hemodialysis patients. The importance of such information is high if leptin is contemplated as a potential therapeutic target in hemodialysis patients.

    It has been established that overproduction of reactive oxygen species (ROS) occurs during hemodialysis causing oxidation of proteins. Alpha-1-antitrypsin is the major circulating anti-protease which contains methionine in the active site. The aim of the present study was to measure the level of serum trypsin inhibitory capacity (sTIC) in hemodialysis patients. This case-control study was performed in 52 hemodialysis patients and 49 healthy controls. sTIC was measured by enzymatic assay. The sTIC was significantly (P< 0.001) lower in hemodialysis patients (1.87 + - 0.67 micron mol/min/mL) than healthy controls (2.83 + - 0.44 micron mol/min/L). Reduction of sTIC may be due to the oxidation of methionine residue in the reactive site of alpha-1 antitrypsin. (author)

    Full Text Available Male erectile dysfunction (ED is an important issue worldwide occurring in 5-69% of men in community-based studies. It is more common in patients with chronic kidney disease (CKD and those on peritoneal as well as hemodialysis (HD, occurring in more than 80% of patients. In Sudan, there is no pre-vious report on ED among patients with CKD. A cross-sectional study was done to determine the prevalence of ED and its associated risk factors among Sudanese CKD patients on HD and those who underwent renal transplant. This was conducted in Khartoum, Sudan from October 2005 to July 2006 including all married men who were on maintenance HD for more than three months and all married men who had received renal transplantation at least three months earlier. Single, divorced/separated men, those whose wives were living away, those who were bed-bound and those with cognitive impairment were also excluded. After obtaining consent for participation, demographic and clinical data were collected by using anonymous questionnaires and the Arabic version of International Index of Erectile Function (IIEF; the Egyptian version. Patients who did not participate in full and proper manner were considered as "non-responders." A total of 146 patients, 106 HD patients, and 40 renal transplant recipients completed the IIEF questionnaire. Non-responders constituted 43.7% and 54.5% of HD and transplant recipient patients, respectively. Blood samples were taken after completion of the IIEF questionnaire to determine the required investigations. ED prevalence was high among our study patients, 83% among the HD patients and 67.5% among the renal transplant recipients. Univariate analysis showed that there was a trend, although non-significant, of older age being associated with ED in both groups. Similar association was seen in those who were under-dialyzed in the HD group and DM in the transplant recipient group. Previous history of ED was significantly associated with current

    Full Text Available Abstract Background Staphylococcus aureus, particularly methicillin resistant (MRSA, is a common pathogen among patients receiving hemodialysis. To evaluate nasal carriage, molecular characterization and effectiveness of decolonization of MRSA among patients receiving hemodialysis in Taiwan, we conducted this study. Methods From January to June 2011, two nasal samplings with a 3-month interval were obtained from patients undergoing hemodialysis in a medical center (CGMH, and in a local hospital (YMH and sent for detection of MRSA. For MRSA carriers, decolonization procedures were administered. All patients in CGMH were observed if MRSA infections occurred during the study period. Results A total of 529 nasal specimens (265 from CGMH and 264 from YMH were collected from 296 patients (161 from CGMH and 135 from YMH. 233 patients participated in both surveys. Average one-time point MRSA carriage rate was 3.8%, and the rate was up to 6.9% for those with two-time point surveys. No additional significant factor for MRSA carriage was identified. Seventy percent of the 20 colonizing MRSA isolates, though categorized as healthcare-associated strains epidemiologically, shared common molecular characteristics of the local community-associated strains. Only one of the 20 MRSA-colonized patients failed decolonization and had persistent colonization, while without any intervention, 17 (61% of 28 patients with methicillin-sensitive S. aureus colonization in the first survey had persistent colonization of a genetically indistinguishable strain. Within the study period, two patients (1.24% in CGMH, one with MRSA colonization (9.1%, developed MRSA infection. Conclusion A substantial proportion of patients receiving hemodialysis in Taiwan had MRSA colonization, mostly genetically community strains. Decolonization procedures may effectively eliminate MRSA colonization and might reduce subsequent MRSA infection in these patients.

    Full Text Available 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.

    Patients on conventional hemodialysis (HD) have elevated markers of oxidative stress and chronic inflammation, which may contribute to a high prevalence of cardiovascular disease. Glutathione (GSH), an important intracellular antioxidant, requires cysteine as a rate-limiting amino acid for its synthesis and riboflavin for its regeneration. We aimed to examine whether erythrocyte GSH (eGSH) concentrations and riboflavin status are influenced by the increased dialysis dose provided to vitamin-supplemented patients receiving home nocturnal hemodialysis (HNHD) (6-8 hours/session, 5-7 nights/week) compared with patients on standard hemodialysis (SHD) (4 hours/session, 3 days/week). This was a cross-sectional comparative study involving 30 patients undergoing SHD or HNHD regimens and a group of 15 healthy control subjects (HC). We measured eGSH concentration by liquid chromatography-tandem mass spectrometry, riboflavin status by eGSH reductase activity coefficient (EGRAC) as well as plasma total cysteine (Cys) and total homocysteine (Hcy), vitamin C by high-performance liquid chromatography, and C-reactive protein (CRP) by standard method. Estimated dietary protein and energy intakes were determined by 3-day food records, and nutritional status was assessed by subjective global assessment (SGA). There were no significant differences among groups in eGSH concentration, EGRAC, dietary protein intake, and SGA score. SHD patients had significantly higher plasma Cys (P patients.

    Home hemodialysis (HHD) is an optimal option for patients requiring renal replacement therapy. It has been noted through research that this type of therapy is more cost-effective than in-centre therapies, and the benefits to patients are well documented (Harwood & Leitch, 2006). As stated by the Ministry of Health and Long-Term Care (MoHLTC), a total of 40% of renal failure patients are expected to do home dialysis (either peritoneal dialysis or HHD) by the year 2010 (Kashani & Motiwala, 2007). Even though the literature indicates that the numbers of those doing home dialysis are declining every year, there is no evidence to demonstrate why the numbers are declining. A quantitative cross-sectional descriptive study was conducted using the Patient Perception Survey and the Jo Pre-Training Assessment Tool (JPAT) to assess in-centre hemodialysis patients' perceptions regarding home dialysis, as well as their self-care ability. The two frameworks utilized were the Theory of Planned Behavior and Orem's Theory of Self-Care. According to the Theory of Planned Behavior, the 26 patients out of 49 who had positive perceptions regarding home dialysis would be expected to participate in home dialysis. However, according to the patients' responses to the domains within the JPAT, only eight out of the 26 would be considered suitable to participate in home dialysis. Only two of the domains, communication and social support, were found to be significantly related to patients'perceptions regarding home dialysis. Health care professionals need to implement interventions that incorporate assessment of communication and social support when addressing home dialysis therapy with a patient with end-stage renal disease (ESRD).

    Full Text Available Introduction: Restless legs syndrome is a neurological disorder; hemodialysis patients seem to suffer more from this syndrome. Although the pathophysiology of restless legs syndrome is still unknown, assessment of factors associated with this syndrome can help to develop medical knowledge in this field. The present study assessed the relationship between restless legs syndrome, serum iron, and serum ferritin levels in patients on hemodialysis. Methods: This descriptive study was carried out with purposive sampling method on 168 hemodialysis patients who referred to the Urmia Taleghani Hospital Hemodialysis Unit. Data were gathered using restless legs syndrome questionnaire and laboratory Index of serum iron and ferritin. Data were analyzed using descriptive and inferential statistical tests. Results: The study results revealed that 38.7 percent of samples complained from restless legs syndrome whose average score serum iron was 78±29.3 μg. Results showed in hemodialysis patients with restless legs syndrome, serum iron and serum ferritin levels were significantly lower than hemodialysis patients without restless legs syndrome (p=0. 02, p=0.005. Conclusion: Considering the high prevalence of restless legs syndrome in patients with hemodialysis, identification of factors associated with this syndrome and providing the necessary solutions for modifying or eliminating the factors, seem to be necessary. Since the relationship between indicators of iron and ferritin and restless legs syndrome in hemodialysis patients is confirmed, the results can be helpful in the treatment and management of these patients.

    Patients with end-stage renal disease (ESRD) have significant impairments in health-related quality of life (HRQOL). In part, this is due to the intrusiveness of the treatment (hemodialysis or peritoneal dialysis) that is required. It is unclear whether hemodialysis or peritoneal dialysis is associated with a higher HRQOL. 192 prevalent patients who self-selected treatment with hemodialysis (either in-center, satellite or home/self-care hemodialysis) or peritoneal dialysis were studied to determine whether treatment with hemodialysis or peritoneal dialysis is associated with a higher HRQOL. Demographic, laboratory and clinical information (including the presence of comorbid conditions using the Charlson comorbidity index) was assessed at baseline. The outcome of interest was HRQOL, which was measured using the Kidney Disease Quality of Life-Short Form (KDQOL-SF), the Short-Form 36 (SF-36) and the EuroQol EQ-5D at baseline and after 6 and 12 months of follow-up. There was no significant difference in HRQOL scores for the SF-36, the EQ-5D and for 9 of 11 KDQOL dimensions for patients treated with hemodialysis or peritoneal dialysis at baseline. As expected, HRQOL was significantly lower for patients who had more comorbid disease, required assistance with their daily care, and for patients with less than a grade 12 education. After controlling for the effect of other important variables, HRQOL (as measured by the EQ-5D visual analog or index scores) did not differ between hemodialysis and peritoneal dialysis patients. HRQOL was stable over time, both for patients who started on hemodialysis or peritoneal dialysis. There is no significant difference in HRQOL for prevalent ESRD patients treated with hemodialysis or peritoneal dialysis. It will be important to determine if this finding holds true for incident patients treated with hemodialysis or peritoneal dialysis.

    Full Text Available Nearly 400 hemodialysis patients treated at 5 different hemodialysis units in Rio de Janeiro were tested for one year for the presence of hepatitis C and B markers. During the same period, samples were also obtained from 35 continuous ambulatory peritoneal dialysis (CAPD patients and from 242 health care workers. Depending on the hemodialysis unit studied, anti-HCV prevalence rates ranging from 47% to 82% (mean 65% were detected. CAPD patients showed a lower prevalence of 17%. The prevalence of antibodies against hepatitis C virus (anti-HCV among health care workers was 2.9%. We observed a hepatitis C attack rate of 11.5% per year in the anti-HCV-negative hemodialysis patient population. An average of 9.4% of the hemodialysis patients were chronic carriers of hepatitis B virus (HBV (range 1.8% - 20.4%, while 48.9% showed markers of previous HBV infection. The HBV attack rate was 4.5% per year (range 0% - 6%. These results indicate an alarming high prevalence of anti-HCV among hemodialysis patients of this studied region.Aproximadamente 400 pacientes de hemodiálise tratados em 5 diferentes unidades no Rio de Janeiro foram acompanhados durante 1 ano para presença de marcadores virais de hepatite B e C.

    Full Text Available 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.

    Objective: The objective of this study was to see echocardiographic findings of cardiac dysfunction in patients of chronic kidney disease (CKD) on hemodialysis. Study Design: Comparative cross sectional study. Place and Duration of Study: Department of nephrology, Pakistan Institute of Medical Sciences. Islamabad from September 2014 to February 2015. Patients and Methods: One hundred patients of either gender were included in this study. Fifty patients of chronic kidney disease stage V on hemodialysis were taken for echocardiography and fifty were normal. Echocardiography was done for cardiac dysfunction. Systolic function was measured by ejection fraction (EF) and fractional shortening (FS). Diastolic function was measured by E/A ratio. Results: Out of 100 patients included in the study, 50 patients were on hemodialysis and 50 were control. Left ventricular end systolic and end diastolic volumes were higher in patients on hemodialysis than controls as well as left atrial enlargement and inter ventricular septum which was statistically significant. Ejection fraction, although normal and fractional shortening decreased in patients on hemodialysis (p<0.05). Diastolic dysfunction was present in 36 patients on hemodialysis, while absent in the control group. Conclusion: Patients with chronic kidney disease on hemodialysis have higher prevalence of cardiac dysfunction. (author)

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

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

    Full Text Available Objective: To evaluate the intake of energy and nutrients by individuals on hemodialysis, following especific recommendations for this population and according to Food Guide for the Brazilian Population. Methods: A cross-sectional study, 118 adult patients, considered stable from, ten dialysis centers in Goiânia, Goiás. Dietary intake was estimated by six 24-hour recalls, and classified as adequate or inadequate, according to specific recommendations for individuals undergoing dialysis and that recommended for a healthy diet. A descriptive analysis was performed. Results: Average dietary intake of 2022.40 ± 283.70 kcal/day; 31.18 kcal/kg/day; 55.03 ± 4.20% carbohydrate; 30.23 ± 3.71% lipid, 1.18 ± 0.23 g protein/kg/day. Important prevalences of inadequacy were observed for the intake of calories (39.0%, protein (39.0% and other nutrients such as retinol (94.9%, saturated fat (87.3%, cholesterol (61,9%, iron (61.0%, potassium (60.2% and zinc (45.0%. Patients had a low intake of fruit food group (1.22 ± 0.89 servings and vegetables (1.76 ± 1.01 servings, dairy products (0.57 ± 0.43 servings and high intake of food group of oils and fats (3.45 ± 0.95 servings, sugars and sweets (1.55 ± 0.77 servings. Conclusion: Observed food consumption imbalance, characterized by excess of oils and fats, especially saturated oils and cholesterol, sugars and sweets, parallel to low intake of fruits and vegetables and dairy products. A considerable percentage of patients did not intake the minimum recommended of calories, protein, retinol, iron, zinc and potassium.

    Full Text Available Background : Vitamin D [(25(OHD] deficiency and insufficiency is common in patients with chronic kidney disease (CKD. 25(OHD has been found to have beneficial effects on bone, cardiovascular and immune functions. There are little data about vitamin D levels in Indian patients on dialysis. This study was undertaken to determine the vitamin D status of Indian CKD patients on hemodialysis. Materials and Methods : We included 45 patients on maintenance hemodialysis coming to Medanta, Medicity, Gurgaon. 25(OHD levels were measured with radioimmunoassay (Diasorin method and parathyroid hormone (PTH was measured using electrochemiluminiscence immunoassay (ECLIA. Results : The mean age of patients was 55 ± 13 years. 32/45 (71% were males. 23/45 (51% were diabetics. The median duration of hemodialysis was 5.5 months (range 1-74 months. 33/45 (74% patients were on thrice weekly hemodialysis. The mean level of vitamin D was 10.14 ± 8.7 ng/ml. Majority of the patients [43/45 (95.5%] were either vitamin D deficient or had insufficient levels. 40/45 (88.9% were vitamin D deficient (levels <20 ng/ml; of these, 29/40 (64.4% had severe vitamin D deficiency (levels <10 ng/ml and 3/45 (6.7% had insufficient levels (20-30 ng/ml of vitamin D. Only 2/45 (4.4% patients had normal levels of vitamin D. 23/45 (51% of patients were receiving calcitriol. The mean levels of serum calcium, phosphorus, alkaline phosphatase, and albumin were 8.8 ± 0.64 mg/dl, 5.0 ± 0.7 mg/dl, 126 ± 10.3 IU/l and 3.6 ± 0.62 g/dl, respectively. PTH levels ranged from 37 to 1066 pg/ml, and the median was 195.8 pg/ml. There was a weak correlation between 25(OHD levels and weight, sex, hemoglobin, albumin, alkaline phosphatase, and presence of diabetes. There was, however, no correlation with duration of dialysis or PTH levels. Conclusion : Vitamin D deficiency and insufficiency are universal in our hemodialysis patients, with severe vitamin D deficiency in two-third of patients.

    Full Text Available Introduction: Dynamometry is a cheap, simple and easily reproduced method to assess muscle strength (MS, which, like other processes of obtaining measurements, displays high sensitivity and specificity for the early detection of any change in the nutritional status. Objectives: To evaluate factors concerning the reduction in MS in patients undergoing hemodialysis (HD. Methods: A single center, crosssectional study was carried out. The following clinical variables were analyzed: sex, age, blood pressure, weight, significant weight loss within the last 36 months, body mass index (BMI, weight gain in between dialysis sessions, hemodialysis treatment time, diabetes, energy and protein intake. Other factors taken into account were: laboratory findings (hemoglobin, hepatogram, electrolyte panel, calcium test, phosphate test, lipid profile, protein analysis, transferrin saturation and hand grip strength (before and after dialysis, on both arms measured through dynamometry. The patients' muscle strength values were compared to those of healthy subjects. Values below the 10th percentile were regarded as abnormal. Mean, median, standard deviation as well as the X2 and the Student's t tests were considered where applicable. A p<0.05 constituted a significant value. Results: There were 73 patients included in this study and 47.95% of them showed low MS with significant strength loss on the arm having the vascular access when compared to the other arm (p 0.00019. A longer hemodialysis treatment time (p 0.026 and a lower BMI (p 0.046 were found to be the two variables with the highest impact on MS. Conclusions: Muscle strength loss in patients undergoing hemodialysis is very common and is associated with a longer HD treatment time and a lower BMI.

    Kathrin Reetz

    Full Text Available 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.

    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.

    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...

    Circulating levels of anions that bind to magnesium and calcium are often altered in patients with CKD. However, it is unknown how these alterations affect the ionized fraction of magnesium and calcium. This cross-sectional study involved patients on maintenance hemodialysis and patients not on dialysis who visited the outpatient department of nephrology. We collected whole-blood samples to measure ionized magnesium and calcium concentrations. Adjusted anion gap was calculated as an integrative index of unmeasured anions. A total of 118 patients on hemodialysis and 112 patients not on dialysis were included. Although the prevalence of hypermagnesemia defined by total magnesium was much higher in patients on hemodialysis than in patients not on dialysis (69% versus 12%; P anion gap than patients not on dialysis (mean [SD]: 14.1 [2.2] versus 5.1 [3.1]), the ionized fractions of magnesium and calcium were inversely associated with the adjusted anion gap. Furthermore, the anion gap significantly improved predictions of ionized magnesium and calcium in patients on hemodialysis. Anions that accumulate in patients on hemodialysis contribute to the lower ionized fraction of magnesium and calcium. Equations that incorporate the anion gap provide better predictions of ionized magnesium and calcium in patients on hemodialysis. Copyright © 2018 by the American Society of Nephrology.

    Full Text Available Factors associated with physical well being were examined in adults with end-stage renal disease (ESRD in two large hemodialysis units of the Royal Medical Services in Jordan. Utilizing the Karnofski scale we measured the functional status of 200 Patients who had been on maintenance hemodialysis for at least 12 months. A Marnofski scale of less than 70 incidents frank disability (Inability to perform routine living activities without assistance, in addition current vocational status was assessed as well as any existing comorbid conditions. The mean age of the study group was 45.2 years (range 16 to 70 and included 108 (54% males and 92 (46% females, there were 39 (19.5% diabetic patients and 27 (13.5% patients were receiving erythropoietin (EPO. The mean hematocrit of the entire group was 27.8%. As measured by Karnofski scale, 64 (32% of the patients were unable to perform routine living activity without assistance; dependence on wheelchair was reported by 9 (4.5% patients. The mean comorbidity index of patients who scored less than 70 on the Karnofski scale was 1.5 compared to 0.7 for those who scored at least 70 on the same scale (p< 0.001. Analysis of factors showed that age and diabetes mellitus affected functional status. Of the laboratory variables measured, only serum albumin concentration correlated significant with Karnofski scale. Fourteen (21.8% of the patients who scored below 70, had serum albumin concentration above 40g/L compared to 66 (48.5% of the patients who scored at least 70 on the Karnofski scale (p< 0.001. We conclude that a significant proportion of patients on maintenance hemodialysis is functionally disabled. The elderly, diabetics, patients with high co-morbidity index and those with low serum albumin are most likely to have poor functional status.

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

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

    Care for the pediatric patient with acute renal failure who requires hemodialysis (including continuous renal replacement therapy) is made more complex, as this intervention may significantly affect drug clearance, potentially altering, to a degree that is largely unknown, the effectiveness and safety of the multiple medications used to manage this complex patient population. This study aims to describe patterns of drug utilization among a large cohort of pediatric patients requiring hemodialysis and to document the easily accessible existing data available for dosing guidance of frequently prescribed medications. Retrospective cohort using the Pediatric Health Information System database. Forty freestanding children's hospitals throughout the United States. Two thousand seven hundred thirty-eight pediatric patients with acute renal failure treated with hemodialysis from 2007 to 2011. A retrospective review of all patients requiring hemodialysis from 2007 to 2011 was conduction using the Pediatric Health Information System Database. Over 6% of pediatric patients with acute renal failure treated with hemodialysis were exposed to hemodialysis for over 2 weeks. Cumulative exposure to distinct drugs increased substantially with more prolonged courses of hemodialysis. Of the 50 most frequently prescribed medications in the cohort with acute renal failure treated with hemodialysis, 10% have readily available and easily accessible information to guide dosing adjustments with the use of hemodialysis. Furthermore, only 18% of these medications have clear recommendations for dosing in pediatric patients of all age groups with renal failure. Pediatric patients with acute renal failure managed with hemodialysis are exposed to a broad variety of medications, with a high prevalence of polypharmacy. There is a trend for longer courses of hemodialysis in these patients, which leads to an increase in cumulative drug exposure, complexity of drug interactions, and potential toxicity

    Poor sleep quality is very common among maintenance hemodialysis patients and has negative impacts on patients' quality of life. Benzodiazepines have traditionally been used in this population; however, they may induce physical dependence and sleep apnea. Nonbenzodiazepine hypnotic medications with less side effects are introduced as alternatives. This study was designed to compare the effect of zolpidem and clonazepam on sleep quality of hemodialysis patients. In a randomized crossover study on 23 hemodialysis patients, sleep quality was assessed using the Pittsburgh Sleep Quality Index at baseline, at the initiation of a 1-week washout period after a 2-week treatment with zolpidem (1 mg) and clonazepam (5 mg to 10 mg), and after the second 2 weeks of treatment. Patients who suffer from any concurrent situations that may affect sleep quality or psychiatric disorders and those on medications affecting sleep quality were excluded. The prevalence of poor sleep quality was 87.8% of the 88 hemodialysis patients who were initially approached. There was a significant negative correlation between iron deficiency and poor sleep quality. Both clonazepam and zolpidem significantly improved sleep quality; however, clonazepam was more effective in decreasing the Pittsburgh Sleep Quality Index scores (P = .03). Zolpidem was better tolerated in the hemodialysis patients. Clonazepam was more effective than zolpidem in the improvement of sleep quality of hemodialysis patients, while zolpidem was better tolerated in these patients.

    Objective To test the performance of appetite assessment tools among patients receiving hemodialysis. Design Cross-sectional. Setting Seven dialysis facilities in Northern California. Subjects 221 patients receiving hemodialysis. Intervention We assessed five appetite assessment tools [self-assessment of appetite, subjective assessment of appetite, visual analogue scale (VAS), Functional Assessment of Anorexia/Cachexia Therapy (FAACT) score and the Anorexia Questionnaire (AQ)]. Main outcome measures Reported food intake, normalized protein catabolic rate (nPCR), and change in body weight were used as criterion measures, and we assessed associations among the appetite tools and biomarkers associated with nutrition and inflammation. Patients were asked to report their appetite and the percentage of food eaten (from 0% to 100%) during the last meal compared to usual intake. Results Fifty-eight (26%) patients reported food intake ≤50% (defined as poor appetite). The prevalence of anorexia was 12% by self-assessment of appetite, 6% by subjective assessment of appetite, 24% by VAS, 17% by FAACT score, and 12% by AQ. All tools were significantly associated with food intake ≤50% (panorexic patients based on the VAS (1.1 ± 0.3 vs 1.2 ± 0.3, p=0.03). Ln IL-6 correlated inversely with food intake (p=0.03), but neither IL-6 nor CRP correlated with any of the appetite tools. Furthermore, only the self-assessment of appetite was significantly associated with serum albumin (p=0.02), prealbumin (p=0.02) and adiponectin concentrations (p=0.03). Conclusions Alternative appetite assessment tools yielded widely different estimates of the prevalence of anorexia in hemodialysis. When considering self-reported food intake as the criterion standard for anorexia, the FAACT score and VAS discriminated patients reasonably well. PMID:26522141

    End-stage renal disease (ESRD) requiring hemodialysis carries up to a 10-fold greater risk of stroke than normal renal function. Knowledge on risk factors and management strategies derived from the general population may not be applicable to those with ESRD. We studied a large ESRD population to identify risk factors and outcomes for stroke. All adult patients receiving hemodialysis for ESRD from January 1, 2007, to December 31, 2012, were extracted from the electronic patient record. Variables associated with stroke were identified by survival analysis; demographic, clinical, imaging, and dialysis-related variables were assessed, and case-fatality was determined. Follow-up was until December 31, 2013. A total of 1382 patients were identified (mean age, 60.5 years; 58.5% men). The prevalence of atrial fibrillation was 21.2%, and 59.4% were incident hemodialysis patients. One hundred and sixty patients (11.6%) experienced a stroke during 3471 patient-years of follow-up (95% ischemic). Stroke incidence was 41.5/1000 patient-years in prevalent and 50.1/1000 patient-years in incident hemodialysis patients. Factors associated with stroke on regression analysis were prior stroke, diabetes mellitus, and age at starting renal replacement therapy. Atrial fibrillation was not significantly associated with stroke, and warfarin did not affect stroke risk in warfarin-treated patients. Fatality was 18.8% at 7 days, 26.9% at 28 days, and 56.3% at 365 days after stroke. Incidence of stroke is high in patients with ESRD on hemodialysis with high case-fatality. Incident hemodialysis patients had the highest stroke incidence. Many, but not all, important risk factors commonly associated with stroke in the general population were not associated with stroke in patients receiving hemodialysis. © 2015 American Heart Association, Inc.

    Full Text Available 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 regur-gitation 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 para-doxical 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.

    Full Text Available Background: Chronic renal failure (CRF presents with an array of cutaneous manifestations. Newer changes are being described since the advent of hemodialysis, which prolongs the life expectancy, giving time for these changes to manifest. Aim: The aim of this study was to evaluate the prevalence of dermatologic problems among patients with chronic renal failure (CRF undergoing hemodialysis. Methods: One hundred patients with CRF on hemodialysis were examined for cutaneous changes. Results: Eighty-two per cent patients complained of some skin problem. However, on examination, all patients had at least one skin lesion attributable to CRF. The most prevalent finding was xerosis (79%, followed by pallor (60%, pruritus (53% and cutaneous pigmentation (43%. Other cutaneous manifestations included Kyrle′s disease (21%; fungal (30%, bacterial (13% and viral (12% infections; uremic frost (3%; purpura (9%; gynecomastia (1%; and dermatitis (2%. The nail changes included half and half nail (21%, koilonychia (18%, onychomycosis (19%, subungual hyperkeratosis (12%, onycholysis (10%, splinter hemorrhages (5%, Mees′ lines (7%, Muehrcke′s lines (5% and Beau′s lines (2%. Hair changes included sparse body hair (30%, sparse scalp hair (11% and brittle and lusterless hair (16%. Oral changes included macroglossia with teeth markings (35%, xerostomia (31%, ulcerative stomatitis (29%, angular cheilitis (12% and uremic breath (8%. Some rare manifestations of CRF like uremic frost, gynecomastia and pseudo-Kaposi′s sarcoma were also observed. Conclusions: CRF is associated with a complex array of cutaneous manifestations caused either by the disease or by treatment. The commonest are xerosis and pruritus and the early recognition of cutaneous signs can relieve suffering and decrease morbidity.

    Full Text Available Introduction: The prevalence of CKD patients in advanced stages with dialysis requirement continues to grow. A goal for the medical team, the patient and their caregivers is to provide a treatment that offers an impact on the prognosis and quality of life (QOL. Methods: In 100 patients with CKD on hemodialysis, randomized assigned, the quality of life by SF-36 was assessed, it was evaluated the functional capacity using the Karnofsky, ability to perform basic tasks of daily life through the index Barthel, presence of depression using the Beck test, family functioning through family APGAR, cognitive state through Minimental and presence of comorbidities using the Charlson index correlated with the sum of physical components (PCS and mental components (MCS of the SF-36 in patients in two renal units in Medellín and Bogotá, Colombia. Results: A decrease in QOL in the physical components (PCS Mental components (MCS regarding the general population. A significant correlation between low PCS and diabetes mellitus (-16 p=0.008 95% CI 2.49 was found. Low MCS showed relation with PTH (p=0.046 95% CI 0.000-0.014, Karnofsky index (p=0.034 95% CI 0.244 to 5.984 and Beck depression test (p=0.000 95% CI -13.606 to 6.253. Conclusions: The QOL of hemodialysis patients is affected with more impact on PCS, there is significant relationship between MCS with functional status and depression. To improve QOL in hemodialysis patients, non traditionally-measured variables should be measured and monitored and the therapeutic focus should be optimized addressed to physical rehabilitation, nutritional, functional and psychological state.

    Full Text Available Introduction: Vascular and valvular calcifications are a frequent complication in dialyzed patients and are connected to an increased morbi-mortality. Many radiological methods (TAC multiple slices and with electrons emission have been used to investigate the presence of vascular calcifications in this population, but only few works have been focused on simple radiology. Objectives: The objectives of this work are to evaluate vascular calcifications by means of Kauppila index in hemodialysis prevalent patients, identify linked risk factors and determine their association with heart valves calcification. Methods: 95 stable patients under hemodialysis were surveyed during a period of 6 months longer. Abdominal Rx simple profile were performed on all patients to evaluate calcification of abdominal aorta by Kauppila index and twodimensional echocardiogram to detect valvular calcifications. Data were collected about sex, age, diabetes, Hypertension, tabaquism, dislipemia and bone-mineral metabolism. Results: 64.5% of the patients showed vascular calcifications. Average Kauppila index was 6.25. Age and time on dialysis correlated with vascular calcifications. In 31.6 % of individuals valvular calcifications were found, which presented significant association with diabetes and Kauppila Index. Conclusions: Vascular and valvular calcifications were frequent in the surveyed population. Kauppila index correlated with age, time on dialysis and valvular calcifications. Heart valves calcification was associated with diabetes.

    Although it is widely accepted that exercise is beneficial in patients with end-stage renal disease as in the general population, it is not easy to incorporate exercise programs into routine clinical practice. This review aimed to investigate the beneficial effects of exercise during hemodialysis and also to introduce various intradialytic exercise programs and their advantages as a first step in combining exercise programs into clinical practice. Aerobic and resistance exercise are beneficial not only in improving physical functioning, including maximal oxygen uptake and muscle strength, but also in improving anthropometrics, nutritional status, hematological indexes, inflammatory cytokines, depression, and health-related quality of life. However, it is not clear whether the beneficial effects of exercise are limited to only relatively healthy dialysis patients. Therefore, the effects of individualized exercise programs for elderly patients or patients with comorbid conditions need to be studied further.

    Full Text Available Purpose: This descriptive study was carried out to reveal the level of physical activity in patients who receive hemodialysis due to chronic kidney failure and to identify its relationship with the prevalence of metabolic syndrome (MetS. Material and method: The study was conducted with 55 patients at the hemodialysis units of Alanya State Hospital and Private Alanya Anadolu Hospital between 10 and 30 June 2013. The study data were collected using the National Cholesterol Education Program, the Adult Treatment Panel III (NCEP-ATP III, a data collection form containing Metabolic Syndrome Diagnosis Criteria, and the International Physical Activity Questionnaire (IPAQ. The data were analyzed using arithmetic mean +/- standard deviation (SD, number and percentage distributions, independent sample t test, crosstabs, One Way Anova, and Pearson and #8217;s Correlation Analysis. Conclusion and suggestions: It was found that 41.8% of the patients were between 50 and 65 years of age, the majority of them were male (58.2%, hemodialysis had been administered to 69.1% of them for at least 36 months, and 50.9% of them met three and more of the MetS criteria. There was no statistically significant relationship between MetS and physical activity levels, but the length of physical activity was longer in those who did not meet the MetS diagnosis criteria (p>0.05. An increase in sedentary time raised the MetS criteria (p<0.05. Conclusion: Nearly 1/2 of the patients were at risk of MetS. Physical activity level being statistically ineffective on MetS can be associated with low physical activity level and longer sedentary time. It can be said that being completely sedentary increases BMI and therefore MetS. The study can be repeated on different samples and the results can be compared. [J Contemp Med 2014; 4(2.000: 69-75

    The accumulation of amyloid in the bone and joint system has recently been recognized as a peculiar disease in patients undergoing long-term hemodialysis (5 years at least), especially in those who use cuprophan membranes. The pathology of amyloidosis is characterized by deposits of amyloid (β microglobulin mainly) in the bone, in the synovia, and in pericapsular soft tissues. The skeleton of 46 long-term hemodialysis patients (19 males and 27 females) was studied by X-ray; bone and joint abnormalities due to amyloid deposition were observed in 45% of cases. The shoulder, hip, and wrist were the most frequently involved joints. Destructive spondyloarthorapathy was present in 15% of cases. The radiographic patterns of AOD are generally divided into axial and peripheral lesions. In the appendicular skeleton abnormalities include: well-defined lytic areas (geodes), pathologic fractures, marginal erosions, and particular soft tissue swelling. Destructive spondyloarthropathy is frequently present in the cervical spine (85% of our cases) and is characterized by narrowing of the invertebral space, marginal erosion, and subchondral bone sclerosis of the vertebral body

    Full Text Available Introduction: Hemodialysis catheters are used for quick establishing of an adequate vascular approach, when urgent hemodialysis is indicated in time of maturation of artery-vein fistula and in patients in whom all other vascular approach have been exhausted. Although the placement of the catheter provides the necessary vascular access, carries a risk of both local-infection exit site of a catheter, as well as systemic complications, including catheter-related infection, septic thrombophlebitis, endocarditis, and other metastatic infections such as lung abscess and brain, osteomyelitis and endophthalmitis. Cases series: We have presented a retrospective series of 5 cases of hemodialysis patients hospitalized at the Clinic of Nephrology and Clinical Immunology, of the Clinical Center of Vojvodina in the period of 2010 to 2017, which have developed different complications of catheter-related infections. Three patients diagnosed with spondylodiscitis and endocarditis in two. In one patient with native valve endocarditis, due to the appearance of other complications, there was a death, while the other patients had an adequate response to therapy. Conclusion: Early recognition of potential complications of catheter-related infections to more successful treatment of these patients.

    Lactic acidosis as a consequence of high serum lactate levels may deepen the metabolic acidosis in patients with end-stage renal failure. Besides, certain antidiabetic may also cause raised lactate levels in diabetic patients. Therefore, it is obvious that the risk of hyperlactatemia is increased by folds in diabetic patients on chronic hemodialysis program. In this study, it is aimed to evaluate the frequency and the impact of increased serum lactate levels in prevalent diabetic hemodialysis patients. A total of 100 diabetic patients who were under maintenance hemodialysis in five different dialysis centers were included in this study. All biochemical parameters, blood gas measurements, echocardiographic data and antidiabetic treatments were statistically analyzed in terms of serum lactate levels. Out of 100 patients, 12 patients had serum lactate levels over normal limits. When the patients with normal or high serum lactate levels were defined as two different groups, statistical significance was detected between serum lactate levels and serum sodium (p = 0.019), potassium (p = 0.037) and bicarbonate levels (p = 0.028). Moreover, in patients with hyperlactatemia, the ejection fraction value was found significantly low (p = 0.005). The frequency of hyperlactatemia was not rare in prevalent diabetic hemodialysis patients. We additionally found that serum lactate level measurement may particularly help to diagnose the occult cardiac failure. However, further large scale studies are required to define the clinical significance of hyperlactatemia in the end-stage renal failure patients with diabetes mellitus.

    The objective of this study was to examine the association between altered taste perception and nutritional status among hemodialysis patients. We performed a post hoc analysis of data from the Hemodialysis study (n = 1,745). Taste perception was assessed at baseline and then updated annually using an item from a quality of life survey that asked "During the past 4 weeks, to what extent were you bothered by loss of taste?" Responses were categorized as normal taste perception if subjects answered "not at all" or altered taste perception if they reported any degree of bother. Time-updated logistic regression models were used to evaluate predictors of altered taste perception. Time-updated linear regression models were used to examine the association between altered taste perception and indices of nutritional status. Multivariable proportional hazards and Poisson models were used to assess association between altered taste perception and mortality and hospitalization, respectively. At baseline, 34.6% reported altered taste perception, which was associated with poorer baseline nutritional status. On time-updated analysis, altered taste perception was associated with a persistently higher proportion of subjects requiring enteral nutritional supplements and lower serum albumin, serum creatinine, normalized protein catabolic rate, protein intake, sodium intake, and mid-arm muscle circumference. Altered taste perception at baseline was independently associated with increased all-cause mortality: adjusted hazard ratio (95% confidence interval) of 1.17 (1.01-1.37), although not with increased rate of hospitalization. Altered taste perception was common among prevalent hemodialysis patients and was independently associated with poorer indices of nutritional status and increased all-cause mortality.

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

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

    Full Text Available Over a two year period, the incidence of hepatitis C virus (HCV infection was evaluated in 29 hemodialysis patients, aged between 15 and 75 years (mean ± SD: 45 ± 39.5 years, from the University Hospital Hemodyalisis Unit, Maracaibo, Zulia State, Venezuela. Anti-HCV antibodies were determined using a fourth generation ELISA (Innotest HCV Ab IV kit and positive blood samples were tested using a recombinant assay kit (Inno-LIA HCV Ab III, both kits from Innogenetics N.V., Belgium. The findings indicate a lack of HCV seroconversion in the hemodialysis patients over the study period, confirmed by the recombinant assay. Risk factors for HCV infection were 0.3270 (95% confidence interval: 0.01323-8.080 in patients undergoing hemodialysis. The findings suggest a lack of significant sources for HCV infection due to the preventive measures to avoid its transmission in the hemodialysis unit.

    Full Text Available Peripheral arterial disease (PAD is common in hemodialysis patients and predicts a poor prognosis. We conducted a prospective cohort study to identify risk factors for PAD including skin perfusion pressure (SPP in hemodialysis patients. The cohort included 373 hemodialysis patients among 548 patients who received hemodialysis at Oyokyo Kidney Research Institute, Hirosaki, Japan from August 2008 to December 2010. The endpoints were lower limb survival (peripheral angioplasty or amputation events and overall survival of 2 years. Our results showed that <70 mmHg SPP was a poor prognosis for the lower limb survival and overall survival. We also identified age, history of cardiovascular disease, presence of diabetes mellitus, smoking history, and SPP < 70 mmHg as independent risk factors for lower limb survival and overall survival. Then, we constructed risk criteria using the significantly independent risk factors. We can clearly stratify lower limb survival and overall survival of the hemodialysis patients into 3 groups. Although the observation period is short, we conclude that SPP value has the potential to be a risk factor that predicts both lower limb survival and the prognosis of hemodialysis patients.

    The purpose of this study was to explore the experience of fluid management in hemodialysis patients by describing how they manage fluid intake and what affects fluid management. Purposive sampling yielded 11 patients who have received hemodialysis for one year or longer in one general hospital. Data were collected through in-depth interviews and analysed using Giorgi's phenomenological method. Data collection and analysis were performed concurrently. The findings regarding how hemodialysis patients manage fluid intake were classified into four constituents: 'recognizing the need for fluid control', 'observing the status of fluid accumulation', 'controlling fluid intake and output', 'getting used to fluid management'. The factors that affect fluid management of hemodialysis patients were revealed as 'willpower', 'change in the mindset', 'support system', and 'emotional state'. The study results show that hemodialysis patients manage fluid intake through food and exercise as well as interpersonal relationships. These findings suggest that strategies in the development of nursing interventions for hemodialysis patients should be directed at assisting them in familiarization with fluid management based on an understanding of their sociocultural contexts.

    Full Text Available The kidneys are very vital organs. Failing kidneys lose their ability to filter out waste products, resulting in kidney disease. To extend or save the lives of patients with impaired kidney function, kidney replacement is typically utilized, such as hemodialysis. This work uses an entropy function to identify key features related to hemodialysis. By identifying these key features, one can determine whether a patient requires hemodialysis. This work uses these key features as dimensions in cluster analysis. The key features can effectively determine whether a patient requires hemodialysis. The proposed data mining scheme finds association rules of each cluster. Hidden rules for causing any kidney disease can therefore be identified. The contributions and key points of this paper are as follows. (1 This paper finds some key features that can be used to predict the patient who may has high probability to perform hemodialysis. (2 The proposed scheme applies k-means clustering algorithm with the key features to category the patients. (3 A data mining technique is used to find the association rules from each cluster. (4 The mined rules can be used to determine whether a patient requires hemodialysis.

    Full Text Available This study was performed to evaluate whether any electrocardiogram (ECG para-meter can predict the presence of hyperkalemia in patients on maintenance hemodialysis (HD. In January 2006, we conducted a cross-sectional study of 80 stable patients with end-stage renal disease from four university-based HD units of Tehran, Iran, receiving conventional thrice-weekly HD. Pre-HD serum electrolyte values and conventional 12-lead ECG were obtained from each pa-tient. Bivariate linear regression was used for assessing relationship of the study variables with hyperkalemia (K + > 5.2 mg/dL. Multivariable logistic regression was used for evaluating inde-pendent relationship between decreased T wave duration (≤ 170 ms and other variables. Bivariate correlation analysis showed a significant inverse correlation between serum potassium concentration and T wave duration (P < 0.05. None of the patients with serum potassium of ≥ 5.6 mg/dL had T wave duration > 200 ms. Multivariate logistic analysis, after adjustment for other factors, also showed a significant relationship between decreased T wave duration (≤ 170 ms and hyper-kalemia. We conclude that although hyperkalemia does not induce the usual ECG changes in HD patients, decreased T wave duration was found to be a good indicator of this lethal 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.

    End-stage renal disease patients on chronic hemodialysis (HD) patients are at risk for both hepatitis B virus (HBV) and hepatitis C virus (HCV) infection, and they may coexist. To determine the prevalence and clinical impact of HBV and HCV infection, we studied poly chain reaction (PCR) and reverse transcription (RT)-PCR on the blood samples of 90 HD patients in Kerman, Iran. ELISA test was used to detect anti-HBc, anti-HBs and HBs Ag. We found that 30 out of 90 (33.3%) patients were PCR-RT-PCR positive for HCV-RNA. No HBV-DNA (0%) was detected through the PCR study in both positive and negative HCV-RNA patient groups. Though none of the samples was HBsAg positive, 10 (33.3%) HCV-RNA positive patients were anti-HBc positive, and 12 (40.7%) were anti-HBs positive. We conclude that prevalence of hepatitis C infection is high in HD patients in our region, but not associated with active HBV infection. (author)

    Bone scintigrams from a total of 75 hemodialysis patients using sup(99m)Tc-methylene-diphosphonate (MDP) were classified into two groups; Group I (56 patients) in which the uptake of the radioactivity appeared to be relatively high in the soft tissue and low in the bone, and Group II (19 patients) in which high uptake in the bone and low uptake in the soft tissue were observed. Patients in Group I were further classified into two subgroups; Group I sub(A) (articular type, 21 patients) which was characterized by relatively high uptake into the joint, and Group I sub(B) (reduction type, 35 patients) where uptake was faint in the whole region of the bone. The classification of patients in Group II was also performed; Group II sub(A) (spinal type, 14 patients) where high spinal uptake was observed, and Group II sub(B) (cranio-facial type, 5 patients) where high uptake into the cranio-facial region was observed. The results were compared with 146 subjects with normal bone scintigram in terms of the ratio of bone to soft tissue uptake (B/S ratio) for the cranial bone, jaw bone, lumbar vertebra and femoral bone, and the ratio of epiphysis to diaphysis uptake (E/D ratio) for the femoral bone. The B/S ratio was low in Group I and high in Group II for the bone studied, and the E/D ratio was markedly high in Group I sub(A). Histobiochemical examination indicated that patients in Group I sub(A) and Group II may have osteomalacia and secondary hyperparathyroidism, respectively. It was considered that the visual classification and semiquantitative study as described here were useful for evaluating the pathological condition of renal osteodystrophy. (author)

    Fractures are an important cause of morbidity in hemodialysis patients. Multiple advances in the treatment of mineral and bone disease in hemodialysis patients have occurred. The purpose of this study was to determine whether the rate of fractures in hemodialysis patients has changed over time. We studied US Renal Data System (USRDS) datasets to determine the rates of hospitalized fractures among hemodialysis patients. The primary outcome was incidence of fractures requiring hospitalization. The fracture rate per 1000 person-years was calculated by year from 1992 to 2009. The first 90 days after initiating dialysis were excluded from analysis. The incidence of hip and vertebral fractures increased from 12.5 fractures per 1000 patient-years in 1992 to 25.3 per 1000 patient-years in 2004 (P fractures increased from 3.2 per 1000 patient-years in 1992 to 7.7 per 1000 patient-years in 2009 (P fracture rate was seen in white patients >65 years of age. After 2004, the incidence rate of these fractures stabilized and subtly declined, but did not decrease significantly. Fracture rates increased significantly in hemodialysis patients from 1992 to 2004, with most of the increase occurring in elderly white patients. Assessment of fracture risk and management in dialysis patients at greatest risk requires greater emphasis and further study.

    Cognitive impairment is defined as a newly appeared deficit in at least two areas of cognitive functions, including disturbances in memory, executive functioning, attention or speed of information processing, perceptual motor abilities, or language. Cognitive impairment is highly prevalent in ESRD patients when compared with the general population. It has also been associated with a decreased quality of life. Cognitive functions in patients with ESRD showed improvement with dialysis and renal transplantation. These findings illustrate the potential importance of evaluating and comparing the effects of hemodialysis and transplantation regarding cognitive performance and thus quality of life in ESRD patients and normal subjects. This study was carried out in 100 patients (50 ESRD patients on regular hemodialysis for at least 6 months and 50 post-transplant patients who had maintained successful kidney graft for at least 3 months). All patients underwent laboratory and psychometric scoring tests, including trail making test part A, trail making test part B, digit span, and mini-mental state examination. Thirty healthy adults matched by age and sex served as a control group. The results showed significant differences in cognitive function tests results between transplant and hemodialysis patients (P0.05). Renal transplantation as a modality of treatment, in ESRD patients, is superior to hemodialysis in terms of cognitive performance improvement. Copyright © 2015 Sociedad Española de Nefrología.

    Dialysis therapy is extremely stressful as it interferes with all spheres of daily activities of the patients. This study is aimed at understanding the perceived illness intrusion among patients on hemodialysis (HD) and to find the association between illness intrusion and patient demo-graphics as well as duration of dialysis. A cross sectional study involving 90 patients with chronic kidney disease (CKD) stage V, on HD was performed during the period from 2005 to 2006. The subjects included were above 18 years of age, willing, stable and on dialysis for at least two months. Patients with psychiatric co-morbidity were excluded. A semi-structured interview schedule covering sociodemographics and a 13 item illness intrusion checklist covering the various aspects of life was carried out. The study patients were asked to rate the illness intrusion and the extent. The data were analyzed statistically. The mean age of the subjects was 50.28 + - 13.69 years, males were predominant (85%), 73% were married, 50% belonged to Hindu religion, 25% had pre-degree education, 25% were employed and 22% were housewives. About 40% and 38% of the study patients belonged to middle and upper socio-economic strata respectively; 86% had urban background and lived in nuclear families. The mean duration on dialysis was 24 + - 29.6 months. All the subjects reported illness intrusion to a lesser or greater extent in various areas including: health (44%), work (70%) finance (55%), diet (50%) sexual life (38%) and psychological status (25%). Illness had not intruded in areas of relationship with spouse (67%), friends (76%), family (79%), social (40%) and religious functions (72%). Statistically significant association was noted between illness intrusion and occupation (P= 0.02). (author)

    Neopterin is a diagnostic or a prognostic biomarker for several pathologies including renal diseases. However, the association between neopterin status and causative main reasons such as diabetes and hypertension for renal disease remains unclear. The aim of the study was to evaluate neopterin levels in diabetes and hypertension patients treated with/without hemodialysis. According to primary renal disorders, the patients undergoing hemodialysis were classified into 4 groups as diabetic nephropathy, hypertensive nephropathy, reflux nephropathy or interstitial nephritis, and others. The controls consisted of healthy subjects, hypertensive subjects, and diabetic individuals without any renal disorder. In the study, both urinary and serum neopterin levels were measured using high performance liquid chromatography and enzyme-linked immunosorbant assay in patients undergoing regular hemodialysis therapy (n=71). The effects of the duration of hemodialysis and treatment of erythropoietin and/or iron on neopterin levels were also evaluated. Neopterin levels were found to be higher in hemodialysis patients than in the healthy controls (P<0.05). A significant difference in neopterin levels was also found between diabetic control patients and diabetic nephropathy patients (P<0.05). A similar significant difference was detected in neopterin levels between hypertensive patients with/without nephropathy (P<0.05). Neopterin may be an early critical marker for progression of nephropathy in diabetic and hypertensive patients in early stages.

    The prevalence and risk factors of cardiovascular disease (CVD) are increasing in end stage renal disease (ESRD) patients. In this study, we sought to research the relationship between the insulin resistance, which is one of the risk factors for CVD, and the inflammation markers, especially C-reactive protein, fibrinogen, uric acid, and homocysteine levels in our patients who were recently diagnosed with ESRD and started hemodialysis. 64 HOMA-IR-positive and 114 HOMA-IR-negative patients were enrolled in this study. Blood samples were obtained from the patients for fasting plasma glucose, insulin, CRP, fibrinogen, uric acid, total homocysteine, urea, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, total protein, and albumin analysis after physical examinations and anamnesis were completed. Fibrinogen and CRP levels of HOMA-IR-positive HD patients were significantly increased compared to non-insulin resistants. Furthermore, there is significant positive relationship between insulin resistance and serum CRP and fibrinogen levels in these HOMA-IR-positive HD patients (r = 0.258, p < 0.001). We found out that the fibrinogen and CRP levels are significantly high in HOMA-IR positive HD patients, according to determine the risk ratio for coronary artery disease in HD patients, and think that an assessment of insulin resistance is necessary.

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

    2010-09-01

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

    Full Text Available Previous studies have shown that insomnia is a common sleep disorder in patients with end-stage renal disease. This study aims to determine the prevalence and risk factors of insomnia in our chronic hemodialysis (HD patients. This is a cross-sectional study conducted in three HD units in Morocco. To assess the prevalence of insomnia, we used a specific questionnaire. Patients complaining of difficulty in falling asleep and/or nocturnal awakenings occurring seven nights a week during the last month were included in the group “insomnia;” the other patients were used as controls. Clinical, biological, and dialysis data were recorded for each patient. Sleep disorders and their subjective causes were also identified. Eighty-nine percent of questioned patients admitted to having sleep disturbances of different degrees. Insomnia was significantly associated with female gender and time of dialysis. Age, body mass index, inter-dialytic weight gain, and blood pressure were similar between the two groups, as well as dialytic parameters and drug use. There was no significant difference in the values of plasma creatinine, urea, hemoglobin, parathyroid hormone, calcium, phosphorus, C-reactive protein, and albumin between the groups. Disorders most frequently encountered in patients with insomnia were waking up at night (90%, difficulty falling asleep (60%, and daytime sleepiness (60%. The restless legs syndrome was seen in half of these patients. The main reported causes of insomnia were anxiety and/or depression (70% and bone pain (67%. Insomnia is common in HD patients and is frequently associated with other disorders of sleep. Female sex and duration on dialysis are the two risk factors found in our study. Insomnia does not appear related to any biochemical or dialysis parameters. Increased attention should be given to the management of dialysis patients regarding the diagnosis and management of insomnia and associated sleep disorders.

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

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

    Full Text Available Malnutrition is a common problem among hemodialysis patients. This factor leads to increased morbidity and mortality. This study evaluates the nutritional status of patients on dialysis and analyses the various parameters used for assessing malnutrition. It is a cross-sectional study of 35 patients aged 18 years and up who have undergone dialysis three days a week for more than a year. The following were analysed: overall subjective assessment technique, Body Mass Index, anthropometric data and biological parameters (serum albumin, serum cholesterol, rate of alkaline reserves and C-reactive protein levels with a dietary three-day survey. Analysis of food survey data was performed using the software Bilnut. The patients’ average age was 46.7 years with a sex ratio of 1.18. Average waist size was 92.7±16.68 cm. Average arm circumference was 27.2±5.6 cm and average calf circumference was 32.03±5.87 cm. Malnutrition was found in 48% of cases according to SGA. Average BMI was 24.4 kg/m2. It was less than 23 Kg/m2 in 48% of cases. Average serum albumin concentration was 33.6 g/l and average CRP level was 6.16 mg/l. The average energy intake (Kcal/Kg/day was 30.87±11.92 the day of dialysis, 27.98±9.31 on a resting day and 29.93±9.42 on another day and the average protein intake (g/kg/day was 1.02±0.44 the day of dialysis, 0.94±0.36 a resting day and 1.04±0.36 on the other day. Malnutrition was frequent among our patients. The assessment of nutritional status in patients on dialysis requires simultaneous combination of several clinical, biologic and dietetic markers. Dietary management is mainly based on food survey regularly established.

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

    This descriptive correlational study was aimed at determining the relationship of hemodialysis shift with sleep quality and depression in 310 hemodialysis patients. Demographic and Clinical Questionnaires, the Pittsburgh sleep quality index, and Beck's Depression Inventory were used to ascertain the aforementioned relationship. Among the patients, 59.6% reported poor sleep quality and 44.8% reported experiencing depression. Results show that these conditions were significantly related to many factors. Although dialysis shift was not significantly related to sleep quality and depression, sleep quality was found significantly associated with age, female gender, illiteracy, unemployment, residence in rural areas, diabetes, addiction to sedatives, and phosphorus levels. A significant relationship was also found between depression and phosphorus levels. Logistic regression predicted age, gender, illiteracy, unemployment, residence in rural areas, and addiction to sedatives as factors for poor sleep quality. A body mass index (BMI) above 30, decreased urea, and increased phosphorus were predicted as factors for increased depression.

    This is a cross-sectional, multicenter, controlled study aiming to evaluate changes of actual dietary nutrient intake in 94 stable hemodialysis patients in respect to 52 normal subjects and guideline recommendations, and to assess the prevalence of signs of malnutrition. Energy and nutrients intake assessment was obtained by a three-day period food recall. Anthropometric and biochemical parameters of nutrition, bioelectric impedance vector analysis, and subjective global assessment (SGA) have been performed to assess nutritional status. SGA-B was scored in 5% of the patients. Body mass index patients, respectively. HD patients showed a lower energy and protein intake in respect to controls, but no difference occurred when normalized per ideal body weight (29.3 +/- 8.4 vs. 29.5 +/- 8.4 Kcal/Kg i.b.w./d and 1.08 +/- 0.35 vs. 1.12 +/- 0.32 Kcal/Kg i.b.w. /d, respectively). Age was the only parameter that inversely correlates with energy (r = -0.35, p protein intake (r = -0.34, p patients, abnormalities of nutritional parameters are less prevalent than expected by analysis of dietary food intake. Age is the best predictor of energy and protein intake in the dialysis patients who ate less than normal people, but no difference emerged when energy and protein intakes were normalized for body weight. These results recall the attention for individual dietetic counseling in HD patients, and also for a critical re-evaluation of their dietary protein and energy requirements.

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

    This study investigated the frequency of malnutrition in geriatric hemodialysis patients according to biochemical, anthropometric, bioelectrical impedance analysis (BIA), modified quantitative subjective global assessment (MQSGA), and geriatric nutritional risk index (GNRI) methods, and the effect of gender on these different parameters. A total of 160 chronic hemodialysis patients (older than 65 years old) were included in this study. There were 82 males (51.2 %) and mean age was 72.8 ± 6.1 years. Nutritional status of patients was evaluated by using serum albumin, body mass index (BMI), triceps skinfold (TSF), mid-arm circumference (MAC), mid-arm muscle circumference (MAMC), calf circumference (CC), BIA, MQSGA, and GNRI. The prevalence of malnutrition according to the aforementioned methods were as following: MAC 62.5 %, MQSGA 60 %, MAMC 50 %, CC 43.1 %, TSF 39.4 %, body fat percentage 33.8 %, albumin 29.1 %, GNRI 15 %, and BMI 8 %. While malnutrition was found to be more prevalent among women according to MQSGA, TSF, and body fat percentage (p = 0.008, p hemodialysis patients according to MQSGA, TSF, MAC, and body fat percentage, there was no difference between genders in terms of malnutrition prevalence according to GNRI, albumin, BMI, and CC.

    Background: Hypervolemia is a major risk factor for hypertension leading to cardiovascular diseases and also a frequent problem in maintenance hemodialysis (MHD) patients. Fluid overload (FO) can be determined by bioimpedance spectroscopy (BIS) which is a new, practical, and non-invasive method. We tried to determine FO by BIS in MHD patients and find out the relationship between FO and clinical features.

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

    Full Text Available Sexual dysfunction may affect 80% of women in hemodialysis. However the specific patterns and clinical correlates of sexual functioning remain poorly described. The aim of this study was to assess prevalence and correlates of the individual domains of sexual functioning in women treated with hemodialysis. We recruited, into this multinational cross-sectional study, women treated with long-term hemodialysis (Collaborative Working Group on Depression and Sexual dysfunction in Hemodialysis study. Self-reported domains of sexual functioning were assessed by the Female Sexual Function Index, which is routinely administered within the network of dialysis patients followed by the working group. Lower scores represented lower sexual functioning. Socio-demographic and clinical correlates of each domain of sexual functioning were identified by stepwise multivariable linear regression. Sensitivity analyses were restricted to women who reported being sexually active. We found that of 1309 enrolled women, 659 (50.3% provided complete responses to FSFI survey questions and 232 (35% reported being sexually active. Overall, most respondents reported either no sexual activity or low sexual functioning in all measured domains (orgasm 75.1%; arousal 64.0%; lubrication 63.3%; pain 60.7%; satisfaction 60.1%; sexual desire 58.0%. Respondents who were waitlisted for a kidney transplant reported scores with higher sexual functioning, while older respondents reported scores with lower functioning. The presence of depression was associated with worse lubrication and pain scores [mean difference for depressed versus non-depressed women (95% CI -0.42 (-0.73 to -0.11, -0.53 (-0.89 to -0.16, respectively] while women who had experienced a previous cardiovascular event reported higher pain scores [-0.77 (-1.40- to -0.13]. In conclusion, women in hemodialysis reported scores consistent with marked low sexual functioning across a range of domains; the low functioning appeared

    Rural-dwelling hemodialysis patients have less frequent contact with nephrologists than urban-dwelling patients, and are known to have higher mortality. We hypothesized that rural-dwelling hemodialysis patients would have more evidence of poorly controlled extracellular fluid volume (ECVF) than otherwise similar urban-dwellers. We studied prevalent hemodialysis patients within a single renal program in Alberta, Canada and assessed ECFV using bioimpedance spectroscopy (BIS). Our primary outcome was impedance vector length (ohm/m) as assessed by BIS using the Xitron Hydra 4200 device, where shorter vector length indicated poorer ECFV control. Because poor ECFV control can lead to hypertension, we also assessed pre- and post-dialysis blood pressure. We measured outcomes at baseline. We studied 228 hemodialysis patients, of whom 115 (50.4 %) and 113 (49.6 %) were urban- and rural-dwelling, respectively. There were no differences in volume control in urban versus rural participants; odds ratio (OR) for vector length in the lowest sex-specific quartile of vector length was 0.93 (95 % CI 0.54, 1.59) after adjusting for age, sex, diabetic status, years since dialysis initiation and phase angle. The odds of very poor blood pressure control (pre-dialysis blood pressure ≥180/100) did not differ between urban and rural participants [fully adjusted OR 0.96 (0.36, 2.60)]. Differences in ECFV control do not appear to explain higher mortality among remote- and rural- dwelling hemodialysis patients, compared to urban-dwellers.

    To assess the knowledge of adult hemodialysis patients and nurses working in dialysis units, specifically with regard to knowledge of phosphorus and other nutrients related to dietary management of end-stage renal disease. Cross-sectional cohort study. Hemodialysis unit. One hundred ninety-one hemodialysis patients and 105 dialysis nurses, as well as 86 control hospital employees who are not health professionals. Nutritional knowledge was assessed by a 25-item chronic kidney disease knowledge assessment tool for nutrition, which includes 15 questions on phosphorus and 10 questions on protein, sodium, and potassium knowledge. The scores obtained by patients were much lower than those of nurses (11.6 ± 3.9 vs. 16.0 ± 2.2, P Patients with phosphorus serum level >5.5 mg/dL showed chronic kidney disease knowledge assessment tool for nutrition scores similar to those of patients with a serum phosphorus level patients (38.4% ± 17.8% vs. 57.3% ± 19.9%, P nutritional knowledge of hemodialysis patients, although higher than the general population, is lower for phosphorus with respect to the other nutrients, such as protein, sodium, and potassium. This occurs even in patients with hyperphosphatemia or those taking phosphate binder medications. Nurses showed the best scores; however, improvement is necessary, especially with regard to knowledge of phosphorus. Training programs on nutrition for nurses and on information for patients should be implemented. They can contribute to achievement of a more effective control of phosphate balance, reduction of costs, and improvement of the quality of care for hemodialysis patients.

    Infective spondylodiscitis is a rare disease. This case review describes the clinical course, risk factors, and outcomes of adult patients on maintenance hemodialysis who presented with infective spondylodiscitis at a single medical center in Taiwan. There were 18 cases (mean age: 64.9 ± 10.8 years) over more than 10 years. Analysis of underlying diseases indicated that 50% of patients had diabetes, 55.6% had hypertension, 55.6% had coronary artery disease, 22.2% had congestive heart failure, 22.2% had a cerebral vascular accident, 16.7% had liver cirrhosis, and 11.1% had malignancies. Sixty-one percent of patients had a degenerative spinal disease and the most common symptom was back pain (83.3%). A total of 38.9% of patients had leukocytosis, 99.4% had elevated levels of C-reactive protein, 78.6% had elevated erythrocyte sedimentation rates, and 55.6% had elevated levels of alkaline phosphatase. The average hemodialysis duration was 72.8 ± 87.5 months, and 8 patients (44.4%) started hemodialysis within 1 year prior to infective spondylodiscitis. Four patients (22.2%) had vascular access infection-associated spondylodiscitis. The lumbar region was the most common location of infection (77.8%), 44.4% of patients developed abscesses, and Staphylococci were the most common pathogen (38.9%). The mortality rate was 16.7%, all due to sepsis. Thirty-three percent of the survivors had recurrent infective spondylodiscitis within 1 year. Infective spondylodiscitis should be considered in hemodialysis patients who present with prolonged back pain with or without fever. Non-contrast MRI is an appropriate diagnostic tool for this condition. Vascular access infection increases the risk for infective spondylodiscitis in hemodialysis patients.

    Patients with end-stage renal disease (ESRD) experience higher rates of hospitalisation, cardiovascular events, and all-cause mortality and are more likely to require admission to the intensive care unit (ICU) than patients with normal renal function. Sepsis and cardiovascular diseases are the most common reasons for ICU admission. ICU mortality rates in patients requiring chronic hemodialysis are significantly higher than for patients without ESRD; however, dialysis patients have a better I...

    Full Text Available Chadi Saifan, Elie El-Charabaty, Suzanne El-SayeghStaten Island University Hospital, Staten Island, NY, USABackground: Elevated total plasma homocysteine is an independent risk factor for arterial and venous thrombosis in patients with normal renal function. Patients on hemodialysis have a high prevalence of mild to moderate hyperhomocysteinemia. Conflicting retrospective analyses and prospective studies have been reported regarding the association between total homocysteine levels and hemodialysis vascular thrombosis. The purpose of this retrospective study was to investigate the relationship between hyperhomocysteinemia and vascular access thrombosis (VAT in patients on hemodialysis.Methods: One hundred and twenty-five patients undergoing dialysis were selected as subjects. The experimental group participants were identified as those having one or more VAT during the previous 13 months and the control group participants had no access thrombosis during the same period. Additional subgroup analysis included the presence of hypertension, diabetes, low-density lipoprotein levels, sex, and use of aspirin.Results: No statistically significant difference was found in total homocysteine levels between the two groups (P = 0.27. No association was found between VAT and sex (P = 0.09, VAT and hypertension (P = 0.96, VAT and diabetes (P = 0.49, nor VAT and low-density lipoprotein level (P = 0.04. A lower rate of VAT was associated with aspirin intake (P = 0.04.Conclusion: This study did not demonstrate a relationship between total homocysteine concentrations and risk of VAT in patients with end-stage renal disease on hemodialysis. There were no significant differences in the number of VAT across additional variables of sex and previous morbidity. Aspirin intake was associated with a lower incidence of VAT.Keywords: hyperhomocysteinemia, vascular access thrombosis, hemodialysis

    Full Text Available Background: Hemodialysis is a critical treatment method, which depends on the vascular access route. Lack of care for the vascular access route could diminish its efficiency in a short time. Regarding this, the present study aimed to evaluate the frequency of nursing care for vascular access route in the hemodialysis patients. Methods: This cross-sectional study was conducted on 20 nurses and 120 hemodialysis patients, who referred to the Hemodialysis Department of Shahid Beheshti Hospital, Babol, Iran, in 2015. The method of nursing care for vascular access route was evaluated using a researcher-made checklist. The data analysis was performed using the descriptive statistics in the SPSS version 16. Results: In total, 14 cases of nursing care were evaluated, in 100% of which all the caring steps, including wearing gloves and a mask, early bolus injections of heparin, washing the catheter tubing, frequent monitoring of blood pressure, rinsing the catheter tubing, returning the blood to the body after hemodialysis, and sterile covering of the puncture site, were observed. However, some of the other techniques, such as the care related to appropriate pump speed when starting the dialysis machine (81.66%, observance of the needle distance from fistula (75.83%, appropriate placement of catheter (75%, pressing the injection site (54.17%, blood pressure monitoring at the end of dialysis (50%, and change of the needle site between two sessions (27.5%, were not adhered to by the nurses. Conclusion: According to the results of this study, some of the nursing care steps, which are necessary in the beginning and end of the hemodialysis, were not accurately followed by the nurses. It is recommended that constant training courses be held for the nurses in this regard.

    2014-03-01

    Full Text Available OBJECTIVE: Depression is the most important neuropsychiatric complication in chronic kidney disease because it reduces quality of life and increases mortality. Evidence demonstrating the association between dialysis shift and depression is lacking; thus, obtaining such evidence was the main objective of this study. METHOD: This cross-sectional study included patients attending a hemodialysis program. Depression was diagnosed using Beck's Depression Inventory. Excessive daytime sleepiness was evaluated using the Epworth Sleepiness Scale. RESULTS: A total of 96 patients were enrolled (55 males, age 48±14 years. Depression and excessive daytime sleepiness were observed in 42.7% and 49% of the patients, respectively. When comparing variables among the three dialysis shifts, there were no differences in age, dialysis vintage, employment status, excessive daytime sleepiness, hemoglobin, phosphorus levels, or albumin levels. Patients in the morning shift were more likely to live in rural areas (p<0.0001, although patients in rural areas did not have a higher prevalence of depression (p= 0.30. Patients with depression were more likely to be dialyzed during the morning shift (p= 0.008. Independent risk factors for depression were age (p<0.03, lower levels of hemoglobin (p<0.01 and phosphorus (p<0.01, and dialysis during the morning shift (p= 0.0009. The hospitalization risk of depressive patients was 4.5 times higher than that of nondepressive patients (p<0.008. CONCLUSION: These data suggest that depression is associated with dialysis shift, higher levels of phosphorus, and lower levels of hemoglobin. The results highlight the need for randomized trials to determine whether this association occurs by chance or whether circadian rhythm disorders may play a role.

    Full Text Available Left ventricular hypertrophy (LVH is frequently observed in chronic dialysis patients and is also highly prevalent in kidney transplant recipients. This study evaluates the impact of long-functioning hemodialysis vascular access on LVH in single center cohort of kidney transplant recipients. 162 patients at 8.7 ± 1.8 years after kidney transplantation were enrolled. Echocardiography, carotid ultrasound, and assessment of pulse wave velocity were performed. LVH was defined based on left ventricular mass (LVM indexed for body surface area (BSA and height2.7. There were 67 patients with and 95 without patent vascular access. Both study groups were comparable with respect to gender, age, duration of dialysis therapy, and time after transplantation, kidney graft function, and cardiovascular comorbidities. Patients with patent vascular access were characterized by significantly elevated LVM and significantly greater percentage of LVH, based on LVMI/BSA (66.7 versus 48.4%, P=0.02. OR for LVH in patients with patent vascular access was 2.39 (1.19–4.76, P=0.01. Regression analyses confirmed an independent contribution of patent vascular access to higher LVM and increased prevalence of LVH. We concluded that long-lasting patent hemodialysis vascular access after kidney transplantation is associated with the increased prevalence of LVH in kidney transplant recipients.

    A comprehensive analysis of sex-specific differences in the characteristics, treatment, and outcomes of individuals with end-stage renal disease undergoing dialysis might reveal treatment inequalities and targets to improve sex-specific patient care. Here we describe hemodialysis prevalence and patient characteristics by sex, compare the adult male-to-female mortality rate with data from the general population, and evaluate sex interactions with mortality. We assessed the Human Mortality Database and 206,374 patients receiving hemodialysis from 12 countries (Australia, Belgium, Canada, France, Germany, Italy, Japan, New Zealand, Spain, Sweden, the UK, and the US) participating in the international, prospective Dialysis Outcomes and Practice Patterns Study (DOPPS) between June 1996 and March 2012. Among 35,964 sampled DOPPS patients with full data collection, we studied patient characteristics (descriptively) and mortality (via Cox regression) by sex. In all age groups, more men than women were on hemodialysis (59% versus 41% overall), with large differences observed between countries. The average estimated glomerular filtration rate at hemodialysis initiation was higher in men than women. The male-to-female mortality rate ratio in the general population varied from 1.5 to 2.6 for age groups sex-specific differences and does not provide information about patients not treated with dialysis or dying prior to a planned start of dialysis. Women's survival advantage was markedly diminished in hemodialysis patients. The finding that fewer women than men were being treated with dialysis for end-stage renal disease merits detailed further study, as the large discrepancies in sex-specific hemodialysis prevalence by country and age group are likely explained by factors beyond biology. Modifiable variables, such as catheter use, showing significant sex interactions suggest interventional targeting. Please see later in the article for the Editors' Summary.

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

    Full Text Available Introduction. Sleep disorders and psychological disturbances are common in end-stage renal disease (ESRD patients. However, despite their frequency and importance, such conditions often go unnoticed, since all patients do not clearly manifest fully expressed symptoms. Objective. This study aimed to determine the prevalence of depression and poor sleep quality and to examine the association between these disorders and demographic, clinical and treatment-related characteristics of ESRD patients on hemodialysis (HD. Methods. The study included 222 patients (132 men and 90 women, mean age 57.3±11.9 years, from 3 HD centers in Central Serbia, which provided us with biochemical parameters and demographic data. Sleep quality and depression were assessed using the Pittsburgh Sleep Quality Index (PSQI and Beck Depression Inventory (BDI, respectively. Results. The average BDI was 16.1±11.3. Depressed patients were significantly older (p=0.041, had a significantly lower dialysis adequacy (p=0.027 and a significantly worse quality of sleep (p<0.001, while they did not show significant difference as regarding sex, employment, marital status, comorbidities, dialysis type, dialysis vintage, shift and laboratory parameters. The average PSQI was 7.8±4.5 and 64.2% of patients were poor sleepers. Poor sleepers were significantly older (p=0.002, they were more often females (p=0.027 and had a significantly higher BDI (p<0.001, while other investigated variables were not correlated with sleep quality. A statistically significant positive correlation was found between BDI and PSQI (r=0.604; p<0.001. Conclusion. Depression and poor sleep quality are frequent and interrelated among HD patients.

    Thirty patients undergoing hemodialysis were evaluated for their periodontal condition through plaque, calculus and gingival indexes; PSR and IgA present in the saliva were also appraised in order to determine the periodontal condition of patients presenting chronic kidney disease. Results obtained demonstrated that in the studied group the plaque, calculus and gingival indexes were high. With regard to these patients' requirement to undergo periodontal treatment, most patients submitted to hemodialysis needed better oral hygiene, in addition to supra and sub gingival scraping and topic application of fluor (code 2). As to the IgA amount present in the saliva, only three patients showed a low density. Patients presenting chronic kidney disease disclosed a tendency for greater bacterial plaque concentration, high formation of dental calculus suggesting the need for periodontal treatment comprising supra and sub gingival scraping.

    Full Text Available Abstract Background Some hemodialysis patients require large doses of erythropoiesis-stimulating agents (ESAs to manage anemia. These patients, termed “ESA hyporesponsive,” have been characterized using various definitions. We applied three definitions of hyporesponsiveness to a large, national cohort of hemodialysis patients to assess the impact of definition on counts and on characteristics associated with hyporesponsiveness. Methods We studied point-prevalent hemodialysis patients on May 1, 2008, with Medicare as primary payer, who survived through December 31, 2008. Included patients received recombinant human erythropoietin (EPO in each month, August-December. Hyporesponsiveness definitions were: above the ninetieth percentile of total monthly EPO dose; above the ninetieth percentile of total monthly EPO dose divided by weight in kg; above the ninetieth percentile of total monthly EPO dose divided by hemoglobin level. Hyporesponsiveness was further classified as chronic, acute, or other. Comorbid conditions were assessed before and concurrent with the hyporesponsive period. Results Women, African Americans, and patients aged Conclusions As associations were similar between patient characteristics and three methods of characterizing EPO hyporesponsiveness, the simplest definition using EPO dose can be used.

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

    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 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

    The nutritional status (NS) of patients on hemodialysis (HD) is a major concern and challenge. Malnutrition is common in these patients and is related to poorer clinical outcomes. To assess the association between the NS and the interdialytic weight gain (IDWG) of patients with chronic kidney disease (CKD) on HD. Cross-sectional study with 322 patients older than 18 years. The NS was assessed by body mass index (BMI), percentage body fat estimated by the sum of four skinfolds (triceps, biceps, subscapular and supra iliac), lean body mass (LBM), serum creatinine and albumin and rate of nitrogen appearance (PNA). The IDWG was evaluated from the sum of the weight difference of 12 hemodialysis sessions (IDWGm). Considering the sample into quartiles IDWGm, it was found that BMI, LBM, serum creatinine ( p nutritional status of these patients.

    Full Text Available Prevalence of cognitive disorders is high in maintenance hemodialysis patients. Montreal cognitive assessment (MoCA is used for detecting and evaluation of cognitive disorder degree in this patient population. In examined patient population, only 5 (12.5% of them had normal cognitive function (MoCA ≥26. Mild cognitive impairment (MoCA 18-26 was found in 65.9% (29 patients, while moderate cognitive disorder (MoCA 10-17 was detected in 6 (21.6% patients. Major cognitive disorder wasn’t detected in examined population. Statistically significant correlation was not established between laboratory parameters and overall MoCA score. Statistically significant correlation, however, was established between MoCA item that evaluates space and time orientation and intermediate secondary hyperparathyroidism and space and time orientation and severe secondary hyperparathyroidism. Hemodynamic instability during hemodialysis and silent ischemia of the brain are increasing risk of appearance of cognitive disorders in maintenance hemodialysis patients.

    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. 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. 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. 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.

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

    Acceptable limb salvage rates underlie the widespread use of endovascular therapy (EVT) for patients with critical limb ischemia (CLI) secondary to isolated infrapopliteal lesions; however, post-EVT delayed wound healing remains a challenge. Predictors of delayed wound healing and their use in risk stratification of EVT in patients with CLI due to isolated infrapopliteal lesions are explored. This was a retrospective multicenter study. 871 consecutive critically ischemic limbs were studied. There was tissue loss in 734 patients (age: 71 ± 10 years old; 71% male) who had undergone EVT between April 2004 and December 2012. The wound healing rate after EVT was estimated by the Kaplan-Meier method. The association between baseline characteristics and delayed wound healing was assessed by the Cox proportional hazard model. Diabetes mellitus and regular dialysis were present in 75% (553/734) and 64% (476/734) of patients, respectively; 67% of limbs (585/871) had Rutherford class 5 CLI; 8% (67/871) of wounds were located in the heel only; 25% (219/871) of limbs had Rutherford 6 (involving not only the heel); and 42% (354/871) of wounds were complicated by infection. The rate of freedom from major amputation at 1 year reached 88%, whereas the wound healing rate was 67%. Median time to wound healing was 146 days. By multivariate analysis, non-ambulatory status (hazard ratio [HR], 1.58; 95% confidence interval [CI] 1.31-1.91) serum albumin wound infection (HR 1.24; 95% CI 1.03-1.50), EVT not based on angiosome concept (HR 1.28; 95% CI 1.06-1.55), and below the ankle (BTA) 0 vessel runoff after EVT (HR 1.45; 95% CI 1.14-1.86) were independent predictors of delayed wound healing. Non-ambulatory status, low albumin level, Rutherford 6 (not only heel), wound infection, indirect intervention, and poor BTA runoff were independent predictors for delayed wound healing after EVT in patients with CLI secondary to infrapopliteal lesions, and their use in risk stratification allows

    Chronic kidney disease associated with hemodialysis can have a variety of musculoskeletal complications, in addition to repercussions in pulmonary function. To evaluate the effects of inspiratory muscle training on inspiratory muscle strength, pulmonary function, and functional capacity in patients with chronic kidney failure undergoing hemodialysis. Non-controlled clinical trial, comprising 15 individuals diagnosed with chronic kidney failure and undergoing hemodialysis. Maximum inspiratory (PImax) and expiratory (PEmax) pressures were assessed by use of pressure vacuum meter reading. Pulmonary function was assessed by use of spirometry. Functional capacity was assessed by use of walked distance and oxygen consumption obtained in the six-minute walk test (6MWT). For eight weeks, the inspiratory muscle training (IMT) protocol was applied during hemodialysis sessions, with load set to 40% of PImax and weekly frequency of three alternate days. A significant increase in the walked distance was observed after training (455.5 ± 98 versus 557.8 ± 121.0; p = 0.003). No statistically significant difference was observed in the other variables when comparing their pre- and posttraining values. The study showed no statistically significant difference in respiratory muscle strength, pulmonary function, and oxygen consumption. An increase in the walked distance was observed in the 6MWT.

    Hemodialysis is associated with an increased risk of neoplasms which may result, at least in part, from exposure to ionizing radiation associated with frequent radiographic procedures. In order to estimate the average radiation exposure of those on hemodialysis, we conducted a retrospective study of 100 patients in a university-based dialysis unit followed for a median of 3.4 years. The number and type of radiological procedures were obtained from a central radiology database, and the cumulative effective radiation dose was calculated using standardized, procedure-specific radiation levels. The median annual radiation dose was 6.9 millisieverts (mSv) per patient-year. However, 14 patients had an annual cumulative effective radiation dose over 20 mSv, the upper averaged annual limit for occupational exposure. The median total cumulative effective radiation dose per patient over the study period was 21.7 mSv, in which 13 patients had a total cumulative effective radiation dose over 75 mSv, a value reported to be associated with a 7% increased risk of cancer-related mortality. Two-thirds of the total cumulative effective radiation dose was due to CT scanning. The average radiation exposure was significantly associated with the cause of end-stage renal disease, history of ischemic heart disease, transplant waitlist status, number of in-patient hospital days over follow-up, and death during the study period. These results highlight the substantial exposure to ionizing radiation in hemodialysis patients.

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

    Protein-energy wasting is highly prevalent in hemodialysis patients, and it contributes to patient morbidity and mortality. The ubiquitin-proteasome system is the major pathway for intracellular protein degradation and it is involved in the regulation of basic cellular processes. However, the role of this system in the determination of nutritional status is largely unknown. To examine a relationship between protein-energy wasting and the ubiquitin-proteasome system, a cross-sectional study of 76 hemodialysis patients was performed. Plasma concentrations of 20S proteasome were studied to evaluate its association with muscle and fat mass, which were investigated by abdominal muscle and fat areas measured using computed tomography and by creatinine production estimated using the creatinine kinetic model. Plasma 20S proteasome concentrations significantly and negatively correlated with abdominal muscle areas and creatinine production (rho = -0.263, P hemodialysis patients. Our findings indicate a relationship between circulating 20S proteasomes and muscle metabolism in these patients. Trial Registration UMIN Clinical Trials Registry UMIN000012341 PMID:25803510

    Full Text Available BACKGROUND: A comprehensive analysis of sex-specific differences in the characteristics, treatment, and outcomes of individuals with end-stage renal disease undergoing dialysis might reveal treatment inequalities and targets to improve sex-specific patient care. Here we describe hemodialysis prevalence and patient characteristics by sex, compare the adult male-to-female mortality rate with data from the general population, and evaluate sex interactions with mortality. METHODS AND FINDINGS: We assessed the Human Mortality Database and 206,374 patients receiving hemodialysis from 12 countries (Australia, Belgium, Canada, France, Germany, Italy, Japan, New Zealand, Spain, Sweden, the UK, and the US participating in the international, prospective Dialysis Outcomes and Practice Patterns Study (DOPPS between June 1996 and March 2012. Among 35,964 sampled DOPPS patients with full data collection, we studied patient characteristics (descriptively and mortality (via Cox regression by sex. In all age groups, more men than women were on hemodialysis (59% versus 41% overall, with large differences observed between countries. The average estimated glomerular filtration rate at hemodialysis initiation was higher in men than women. The male-to-female mortality rate ratio in the general population varied from 1.5 to 2.6 for age groups <75 y, but in hemodialysis patients was close to one. Compared to women, men were younger (mean = 61.9 ± standard deviation 14.6 versus 63.1 ± 14.5 y, were less frequently obese, were more frequently married and recipients of a kidney transplant, more frequently had coronary artery disease, and were less frequently depressed. Interaction analyses showed that the mortality risk associated with several comorbidities and hemodialysis catheter use was lower for men (hazard ratio [HR] = 1.11 than women (HR = 1.33, interaction p<0.001. This study is limited by its inability to establish causality for the observed sex

    One-size-fits-all protocol-based approaches to anemia management with erythropoiesis-stimulating agents (ESAs) may result in undesired patterns of hemoglobin variability. In this single-center, double-blind, randomized controlled trial, we tested the hypothesis that individualized dosing of ESA improves hemoglobin variability over a standard population-based approach. We enrolled 62 hemodialysis patients and followed them over a 12-month period. Patients were randomly assigned to receive ESA ...

    Hemodialysis patients experience a high degree of psychosocial impairment. The psychosocial status of hemodialysis patients after Hurricane Katrina was evaluated using the Hurricane Coping Self-Efficacy (HCSE) measure, the Short Form-12 Health Survey (physical component summary [PCS] and mental component summary [MCS]), and the Center for Epidemiologic Studies Short Depression Scale (CES-D). These scales were administered to 391 hemodialysis patients (86% participation rate), 7 to 14 months after Hurricane Katrina. The mean score (standard deviation) was 36.2 (9.6) for the HCSE scale, 37.1 (10.9) and 46.7 (12.7) for the PCS and MCS, respectively, and 10.0 (6.5) on the CES-D. Symptoms of depression (CES-D scores > or =10) were present in 45.5% of patients. After age, race, and gender adjustment, evacuating less than 2 days before Hurricane Katrina making landfall and more fear of dying were associated with less favorable scores on the HCSE, MCS, and CES-D scales. Patients placed in a shelter and with a longer displacement had significantly lower MCS scores and more depressive symptoms. More depressive symptoms were observed among patients hospitalized in the month after the storm. Those who evacuated to a hotel, with more fear of dying and who were hospitalized in the month after Hurricane Katrina had lower scores on the PCS. Impaired psychosocial status was common among dialysis patients surviving Hurricane Katrina and associated with reduced coping. These data demonstrate the need for screening and management of psychosocial issues in hemodialysis patients after disasters.

    Full Text Available Controlled attenuation parameter (CAP is a non-invasive method for measuring hepatic steatosis (HS. Non-alcoholic fatty liver disease (NAFLD is closely related to cardiovascular diseases (CVDs. CVDs are the leading cause of morbidity and mortality in hemodialysis patients. The aim of this study was to investigate the prevalence of NAFLD in hemodialysis patients.We prospectively enrolled patients undergoing chronic hemodialysis, as well as patients with normal renal function who served as controls. The control group patients were referred by an endocrinologist to be tested for NAFLD; most of these patients had diabetes, hypertension, or dyslipidemia. We excluded those with excess alcohol intake, use of drugs known to induce HS, chronic viral hepatitis, or CAP failure. CAP ≥ 238 dB/m was used as a cutoff suggesting HS. An increased liver kidney contrast, as defined by ultrasound, was used to make the diagnosis of HS.Three hundred and forty-three hemodialysis patients and 252 control group patients were enrolled. Among the hemodialysis patients, 192 (56.0% had CAP- or ultrasound-identified HS compared with 91 (26.5% who only had ultrasound-identified HS (P<0.001. Among the control group patients, 212 (84.1% had CAP- or ultrasound-identified HS compared with 180 (71.4% who only had ultrasound-identified HS (P<0.001.The prevalence of NAFLD in the hemodialysis patients was 56%. The number of diagnoses of NAFLD made by using CAP combined with ultrasound was more than 2 times the number made with ultrasound alone in the hemodialysis patients. Therefore, we suggest the use of CAP combined with ultrasound to screen for NAFLD in hemodialysis patients.

    Full Text Available The objective of this systematic literature review was to identify the occurrence of opportunistic enteric parasites in chronic kidney patient undergoing hemodialysis. The review consisted on searching articles published on MEDLINE, LILACS, SciELO, and PubMed databases between 1991 and 2013. A total 178 articles were identified, ten of which were considered relevant for the present study. In the referred studies, the researchers demonstrated that immunosuppressed patients undergoing hemodialysis are potentially infected by opportunistic enteric agents. Further studies are needed on this topic, as there is a growing global concern with chronic kidney diseases and the potential for these patients contracting opportunistic diseases, which, inclusively, could contaminate hospital environments with opportunistic enteric protozoa.

    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.

    Inflammation contributes to hemopoiesis by lowering responses to epoetin (EPO) and to an increase in the mortality of patients on hemodialysis. However, nutritional status might alter associations among inflammation, EPO responsiveness, and the risk of mortality. We assessed the effect of inflammation on mortality according to nutritional status among EPO responses in a cohort of prevalent hemodialysis patients. The observational cohort study analyzed data from the Japanese Dialysis Registry (2005-2006; n = 36,956; mean follow-up 11.5 months). Patients were categorized into tertiles of the EPO responsiveness index (ERI; the weekly weight-adjusted EPO dose [IU/kg/week] divided by hemoglobin [g/dL]) and an EPO-free group. Body mass index (BMI) and C-reactive protein (CRP) levels were measured. Bimodal peaks indicated associations between CRP and BMI in each group. Hazard ratio (HR) curves of CRP for mortality according to BMI in the upper ERI tertile, particularly among those with diabetes mellitus (DM), were reverse J-shaped. However, HR curves in the other groups were increased below a threshold BMI of 21 kg/m(2). These associations were confirmed in propensity score-matched populations. Risk of CRP for death is apparently changed by BMI in hemodialysis patients with a lower EPO response, especially in those with DM. Copyright © 2014 National Kidney Foundation, Inc.

    This study aimed to compare the longitudinal performance of the malnutrition-inflammation score (MIS) and the geriatric nutritional risk index (GNRI), two nutritional scores for patients on maintenance hemodialysis. Nutritional scores, dietary intake, biochemical markers, and body composition analysis were performed at baseline and at 6, 12, and 18 months after enrollment (which took place from January through December 2006) on 75 prevalent hemodialysis patients (43% women, mean age 64.8 ± 11.9 years). The patients underwent simultaneous MIS and GNRI assessments calculated by two independent examiners from baseline. The study period was 46.8 ± 16.4 months. GNRI had higher interobserver agreement (weighted κ-score 0.98) than MIS (weighted κ-score 0.62). Longitudinally, a 1-unit increase in MIS was associated with a 0.41 kcal/kg per day reduction in daily energy intake (Pnutritional biomarkers, inflammation (IL-6), and body composition parameters. Both scores expressed significant associations with prospective hospitalization, whereas only MIS was associated with mortality in this cohort. The multivariate Cox proportional hazard ratio was 1.15 for death for each 1-unit increase in the MIS (95% confidence interval, 1.03-1.3; P=0.02). Both MIS and GNRI are valid tools for longitudinal assessment of hemodialysis patients' nutritional status. MIS has lower interobserver reproducibility than GNRI; however, MIS is more comprehensive than GNRI.

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

    Full Text Available Studies have shown that sleep disorders are common among dialysis patients; however, few studies have compared the prevalence of different sleep disorders in patients on peritoneal dialysis (PD and hemodialysis (HD. We used questionnaires to assess the prevalence of common sleep disorders in dialysis patients. We compared the prevalence of sleep apnea (SA risk, restless legs syndrome (RLS, insomnia, and excessive daytime sleepiness (EDS, as well as sleep quality, in both groups. Of the 227 patients who were enrolled in the study, the total number of patients on HD was 188 (82%, while the total number of patients on PD was 39 (18%. There were no significant differences between the two groups regarding age, neck size, or duration on dialysis (all P >0.05. The estimated overall prevalence of SA was significantly higher in PD patients in comparison with HD patients (92% and 67%, respectively; P <0.05. The prevalence of insomnia was similar in both groups. The prevalence of RLS was significantly greater in PD than in HD patients (69% and 46%, respectively; P <0.05. In addition, EDS was significantly higher in PD than in HD patients (77% and 37%, respectively; P <0.05. Our study shows that sleep disorders are common in dialysis patients; however, SA, EDS, and RLS were more common in PD patients than in HD pa-tients. Poor sleep quality and insomnia were comparable in both groups.

    Full Text Available Background: Identifying the sources of variation in QTc measurementsis important for preventing arrhythmias during and afterhemodialysis. The present study was designed to determine thecorrelation between the type of hemodialysis buffer and thechanges in QTc interval in patients on chronic hemodialysis.Methods: Fifty-nine patients on chronic hemodialysis whoreferred in winter 2007 to hemodialysis centers of Ghaem andHashemi Nejad hospitals, in Mashhad, Iran, were divided intotwo groups according to their last dialysate buffer: acetate orbicarbonate. Electrocardiography, arterial blood gas parameters,serum K+, Na+, ionized calcium, and albumin levels weremeasured prior to and after hemodialysis in all patients.Results: All arterial blood gas parameters and serum electrolytesconcentrations were increased except K+ levels that weresignificantly decreased with hemodialysis. PCO2 and QTc intervalswere slightly increased in all patients, however thisincrease was not statistically significant. We found that thetype of dialysate affected the QTc interval, HCO3, base excess,base excess of extra cellular fluid, and base bufferchanges with no effect on ionized calcium, pH, PCO2, andserum albumin concentration. QTc interval was prolonged byusing bicarbonate and shortened by using acetate dialysatebuffer. We found no correlation between the variations of QTcinterval and serum electrolytes or arterial blood gas parametersin either group.Conclusion: Bicarbonate buffer use in hemodialysis prolongedQTc interval and acetate buffer shortened it. This effectis independent of serum electrolytes and pH changes duringhemodialysis. The effect of bicarbonate buffer is probablydue to more tolerability of ultra filtration, more effectiveedema reduction and augmented body electro-conductivity.

  12. Recurrent Hypoglycemia in a Hemodialysis Patient Related to Propoxyphene Treatment

    Full Text Available There are various etiologies for hypoglycemia in patients with chronic renal failure, and its pathogenesis is complex. Concomitant use of medications is the most common cause. We report a rare case of an 82-year-old woman with type 2 diabetes mellitus in end-stage renal disease undergoing maintenance hemodialysis, who experienced recurrent symptomatic hypoglycemia during treatment with propoxyphene for pain relief. Hypoglycemia occurred simultaneously with elevated levels of serum immunoreactive insulin and C-peptide. After discontinuing propoxyphene, hypoglycemia mitigated and the level of insulin returned to normal range. Our case reminds us that propoxyphene-induced hypoglycemia should not be ignored, especially in hemodialysis patients with cold sweats, agitation and depressed consciousness.

    Cardiovascular disease is the leading cause of morbidity and mortality in patients receiving hemodialysis. Systemic metabolic perturbation is one of the hallmark abnormalities in patients at high cardiovascular risk. We sought to determine the relationship between circulating ketone body and clinical outcomes in patients with prevalent hemodialysis. We retrospectively assessed the relationship between serum β-hydroxybutyrate (βOHB), the most abundant ketone body in the circulation, and prognosis in 405 stable hemodialysis patients. During a mean follow-up of 3.2±0.9 years, there were 54 major adverse cardiovascular events (defined as cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, and hospitalization attributed to heart failure) and 67 all-cause deaths. Major adverse cardiovascular events rates increased from 11.1 per 1000 person-years in the lowest βOHB quintile (409 μmol/L). After adjusting for demographic characteristics, coronary artery disease, and atrial fibrillation, the highest βOHB quintile was associated with increased risk of major adverse cardiovascular events compared with the lowest quintile (hazard ratio, 10.2; 95% confidence interval [3.35-44.0]; P <0.001). Increased quintiles of βOHB were independently and incrementally associated with major adverse cardiovascular events over the model based on an established risk score (the second Analyzing Data, Recognizing Excellence and Optimizing Outcomes cohort score) and N-terminal pro-B-type natriuretic peptide (chi square 39.9 versus 21.7; P <0.001; c-statistics, 0.713). Sensitivity analyses also confirmed the robustness of association between βOHB and all-cause death. Increased serum βOHB levels were independently associated with cardiovascular events and all-cause death in patients receiving hemodialysis. These results highlight the need for future studies to understand the mechanisms underlying these observations. © 2017 The Authors. Published on behalf of the

    To evaluate the spectrum of mineral abnormalities and bone disease (BD) in hemodialysis patients at Jordan University Hospital (JUH), Amman, Jordan. A cross-sectional study was conducted among 63 patients (38 males and 25 females), mean age 44.19 years (range 17-76 years), with chronic kidney disease (CKD) on regular hemodialysis at JUH between November 2004 and April 2005. All patients have undergone complete blood count, chemistry profile, alkaline phosphatase, serum albumin, intact parathyroid hormone (iPTH) and plain x-rays. Bone disorders were identified in 45 patients on x-rays (70%). Osteopenia was found in 43 patients (68.3%), subperiosteal resorption in 24 patients (38.3%) and metastatic calcification in 22 patients (35%). Hypocalcemia was found in 28.6% and hypercalcemia in 7.9%. All patients were taking calcium carbonate, and 55.5% of patients were on vitamin D supplements. The calcium levels in 63.5% and the phosphorus levels in 50.8% of patients were within the recommended guidelines of the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (K/DOQI). Serum i-PTH level was above 300 pg/ml high turnover bone disease in 24.6% of patients, 21.3% had iPTH of 150-300 pg/ml target, and 44.3% had i-PTH levels below 100 pg/mL suggesting a dynamic bone disease. Patients with severe bone disease had a statistically significant higher iPTH levels (p<0.005). Bone disease and mineral abnormalities are common in hemodialysis patients at JUH. Earlier detection of bone disease and better overall management strategy may reduce the frequency and severity of bone disease in CKD patients in Jordan. (author)

    Full Text Available Bioimpedance analysis is a reliable technique for determining post dialysis target weight. Using this technique, we can understand body fluid status easier and conveniently. Moreover this technique can be used for check nutrition status and nutritional status of dialysis patients. We compared the body fluid status and nutrition status between hemodialysis (HD patients and peritoneal dialysis (PD patients by BCM (Body composition monitor technique. We studied 48 (30 males and 18 females PD patients, 21 (10 males and 11 females HD patients. Body composition monitoring (BCM, Fesenitus Medical Care, Germany was used as a tool for the analysis of bioimpedance. Extracellular water, Total body water, Intracellular water, Overhydration, E/I, Lean tissue mass, Fat Tissue mass was measured and those results were compared between two groups. HD patients were more hydrated than PD patients (61.9% vs. 35.4% and nutritional status such as LTI was poorer than peritoneal dialysis patients (11.7±1.7 vs. 15.3±2.6. Although total body water is more abundant in peritoneal patients (29.4±5.5L vs. 35.9±6.2L, Extracellular water and intracellular water ratio was relatively higher in Hemodialysis patients (E/I 0.98±0.13 vs. 0.87±0.12. The nutrition status was better in PD patients by comparing the percent of lean tissue mass (LTM% between two groups (LTM% 52.1±10.6% vs. 66.8±11.3. In conclusions, Hemodialysis patients were more hydrated with poorer nutrition status than peritoneal dialysis patients, but, due to the significant difference of age between two groups, further study should be required.

    Full Text Available Introduction. A bone marrow biopsy is a useful procedure for the diagnosis and staging of various hematologic and systemic diseases. The objective of this study was to investigate whether the findings of bone marrow studies can predict mortality in chronic hemodialysis patients. Methods. Seventy-eight end-stage renal disease patients on maintenance hemodialysis underwent bone marrow biopsies between 2000 and 2011, with the most common indication being unexplained anemia followed by unexplained leukocytosis and leukopenia. Results. The survivors had a higher incidence of abnormal megakaryocyte distribution P=0.001, band and segmented cells P=0.021, and lymphoid cells P=0.029 than the nonsurvivors. The overall mortality rate was 38.5% (30/78, and the most common cause of mortality was sepsis (83.3% followed by respiratory failure (10%. In multivariate Cox regression analysis, both decreased (OR 3.714, 95% CI 1.671–8.253, P=0.001 and absent (OR 9.751, 95% CI 2.030–45.115, P=0.004 megakaryocyte distribution (normal megakaryocyte distribution as the reference group, as well as myeloid/erythroid ratio (OR 1.054, CI 1.012–1.098, P=0.011, were predictive of mortality. Conclusion. The results of a bone marrow biopsy can be used to assess the pathology, and, in addition, myeloid/erythroid ratio and abnormal megakaryocyte distribution can predict mortality in chronic hemodialysis patients.

    Background and Objectives. There is no data analyzing the outcome of blood transfusions and oral iron therapy in patients with kidneys failure in sub-Saharan Africa. The present study aimed to fill that gap and assess the value of ferritin in the diagnosis of iron overload and deficiency. Design. From January to February 2012, we prospectively studied 85 hemodialysis patients (78% of males and 22% of females aged 20 to 79 years) attending the Gabonese National Hemodialysis Centre. Results. Correlation studies showed (a) a strong positive linear relationship between the number of blood transfusions and high serum ferritin in hemodialysis patient (Spearman r : 0.74; P value: 0.0001); (b) a weak association between the number of blood transfusions and serum iron concentrations (Spearman r : 0.32; P value: 0.04); (c) a weak association between serum ferritin and serum iron (Spearman r : 0.32; P value: 0.003). Also, the strength of agreement beyond chance between the levels of ferritin and iron in the serum was poor (κ = 0.14). The prevalence of iron overload was 10.6%, whereas the prevalence of iron deficiency was 2.3%, comparing (1) patients with a maximum of one transfusion not on iron therapy; (2) patients with a maximum of one transfusion on iron therapy; (3) polytransfused patients not on iron therapy; and (4) polytransfused patients on oral iron therapy. The “Kruskal-Wallis test” showed that ferritin levels varied significantly between the groups (P value: 0.0001). Conclusion. Serum ferritin is not reliable as a marker of iron overload. For patients undergoing regular transfusion we recommend routine serum ferritin measurement and yearly measurement of LIC. PMID:25685597

    Visual impairments are associated with low quality of life, impairment of daily activities, and accidental falls. As dialysis patients are increasingly older and more disabled, we sought to assess visual impairments within an elderly dialysis population. Based on data from the general population, we hypothesized that more than 30% of dialysis patients 65 years or older would have visual impairment manifested by loss of visual acuity, depth perception, or contrast sensitivity. Single-center cross-sectional study. Patients established on hemodialysis therapy, age older than 65 years. The proportion of elderly hemodialysis patients with impairments in visual acuity, contrast sensitivity, and depth perception. Lighthouse Near Visual Acuity Test, Lea Screener contrast sensitivity test (Goodlite, MA, USA), Titmus Stereotest, Folstein Mini-Mental Status Examination. 152 of 159 patients (95.6%) had visual acuity levels less than age-expected values. Under North American (American Medical Association, edition 4) guidelines for disability compensation, 62 patients (39.0%) fulfilled criteria for legal blindness. Sixty patients (37.0%) had poor contrast sensitivity and 48 (30.6%) failed the Housefly component of the Titmus Stereotest. Failing the Housefly component was associated with a lower Folstein Mini-Mental Status Examination score (23.4 +/- 4.2 v 25.1 +/- 3.5; P = 0.01). This study is limited by the cross-sectional study design and abbreviated test protocol used for vision assessment. Results of this study suggest that elderly hemodialysis patients have a high frequency of visual impairment. Formal low vision assessment and low vision rehabilitation may be useful in elderly dialysis patients. Additional study is required to determine whether the absence of depth perception in this patient group is associated with deteriorating cognitive function.

If the patients of chronic renal failure are in End Stage Renal Disease (ESRD, the kidney needs replacement therapy to help its function. This therapy is called Continuous Renal Replacement Therapy (CRRT or Hemodialysis (HD. Hemodialysis therapy may influence to the imbalance of oxyhemoglobin in the blood. Patients undergoing hemodialysis may experience intradialytic nausea and vomiting. The objective of this study is to identify whether there is a relationship between pre-dialysis oxygenation status through oxygen saturation (SpO2 and respiratory rate (RR examination and the intradialytic nausea-vomiting occurrence. Method: This research is a comparative research with analytical cross sectional design. This research was conducted in hemodialysis room in Public Hospital of Panembahan Senopati Bantul. The subject of the research was taken using total sampling, by paying attention to research ethics. The total research subjects are 183 respondents. The researchers measured the oxygen saturation and patients’ respiratory rate and examined the intradialytic nausea and vomiting complaints. Result: The analysis result of Fisher’s exact in this research shows p value of 0,000 both in bivariate analysis of oxygen saturation to the nausea and vomiting occurrence and in bivariate analysis of the respiratory rate to the nausea and vomiting occurrence. The multivariate analysis employing regression logistic shows that the OR of oxygen saturation is 73,57, this means that the measurement of the abnormal oxygen saturation has the chance of seventy three times more to the nausea and vomiting occurrence, if compared to the patients with normal oxygen saturation. Conclusion and Suggestion: Intradialytic nausea and vomiting is one of the causes

    Leptin is secreted by adipose tissue and decreases appetite. However, the role of leptin in the pathogenesis of hemodialysis (HD)-related malnutrition has not been fully evaluated. The aim of study was to investigate the association between the serum leptin levels, serum C-reactive protein (CRP) levels, and nutritional status in hemodialysis patients. This analytical descriptive study included 45 hemodialysis patients and 40 healthy subjects. Biochemical parameters and serum leptin levels were measured. The nutritional status was evaluated using a food frequency questionnaire (FFQ) and the calculation of the body mass index (BMI). Serum leptin (P nutritional factors in hemodialysis patients.

    Full Text Available Vascular calcification is associated with increased morbidity and mortality among chronic kidney disease (CKD patients. The aim of the study was to assess the abdominal aortic calcification (AAC in predialysis CKD patients and patients on hemodialysis (HD and to study the risk factors associated with it. In this prospective study, 205 patients were including 104 patients with predialysis CKD and 101 patients were on maintenance hemodialysis. AAC was assessed using lateral lumbar radiography. Blood urea nitrogen, serum creatinine, albumin, calcium, phosphorus, highly sensitive C-reactive protein (hsCRP and total cholesterol were analyzed. AAC was observed in 26 % of predialysis CKD patients and 34% in HD patients. Using multivariate analysis, the age (P = 0.001 was identified as independent predictor for the presence of AAC in predialysis patients, and for HD, the predictors were age (P = 0.025, time on dialysis (P = 0.001, hsCRP (P = 0.002, and corrected calcium (P = 0.030. In conclusion, the prevalence of AAC varies mainly with age and glomerular filtration rate levels in predialysis CKD patients. Advanced age, time on dialysis, and inflammation may be associated with presence and extent of AAC in HD patients. Further research into the risk factors and outcome for AAC is warranted.

    The kidneys of patients with chronic renal failure undergoing maintenance hemodialysis may show different variances or complications. Most common are secondarily acquired renal cysts, which my be found in as many as 92% of patients after 8 years of hemodialysis. Single (in 12.5% of patients) or multiple (8.3%) cysts with bleeding are common; additionally, hematuria or ruptured cysts may be found. Bleeding into cysts is more common in patients with autosomal dominant polycystic kidney disease. Due to the decreasing urinary production development of kidney stones is very uncommon, but calcification in or around cysts can be found in 71% of patients. Kidney tumors occur 41 times more often in patients with chronic renal failure than in patients without kidney disease. We detected tumors in 4.2% of our patients on long-term dialysis. Diagnostic differentiation of the relatively slow growing and fairly late metastasizing malignant tumors from adenomas is not possible. Nevertheless, we screen our patients every 3-4 years. Computed tomography is superior to ultrasonography for this purpose, because ultrasonography lacks the necessary sensitivity in this group of patients. (orig.) [de

    Full Text Available Abstract Background The hepatitis E virus (HEV has a global distribution and is known to have caused large waterborne epidemics of icteric hepatitis. Transmission is generally via the fecal-oral route. Some reports have suggested parenteral transmission of HEV. Anti-HEV prevalence data among chronic hemodialysis (HD patients are few and give conflicting results. Methods This cross-sectional study was conducted in August of 2004. We tested 324 chronic HD patients attending three different units in the city of Tabriz, northwestern part of Iran, for anti-HEV antibody. A specific solid- phase enzyme-linked immunoassay (Diapro, Italy was used. Results The overall seroprevalence of hepatitis E was 7.4 %(95% CI: 4.6%–10.6%. The prevalence rate of HBV and HCV infection were 4.6% (95% CI: 2.3%–6.9% and 20.4% (95% CI: 16%–24.8%, respectively. No significant association was found between anti-HEV positivity and age, sex, duration of hemodialysis, positivity for hepatitis B or C virus infection markers and history of transfusion. Conclusion We observed high anti-HEV antibody prevalence; there was no association between HEV and blood borne infections (HBV, HCV, and HIV in our HD patients. This is the first report concerning seroepidemiology of HEV infection in a large group of chronic HD individuals in Iran.

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

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

    Full Text Available Objectives: To compare the prevalence of unexplained pulmonary artery hypertension (PAH in hemodialysis (HD and peritoneal dialysis (PD patients and to compare laboratory parameters between patients with unexplained PAH and those with normal pulmonary artery pressure (PAP. Methods: We retrospectively reviewed the medical records of 278 chronic HD and 145 chronic PD patients. Laboratory findings including hemoglobin, calcium, phosphorus, alkaline phosphatase, albumin, parathyroid hormone level, serum iron, total iron binding capacity, ferritin, creatinine and blood urea nitrogen were documented. The results of transthoracic Doppler echocardiography were used to determine the pulmonary artery pressure (PAP. PAH was defined as a systolic pulmonary artery pressure (SPAP ≥35 mmHg. To rule out secondary PAH, patients with cardiac disease, pulmonary disease, collagen vascular disease, volume overload at the time of echocardiography and positive human immunodeficiency virus test were excluded. Results: Data from 34 patients in group HD and 32 individuals in group PD were analyzed. The median age of the study population was 57 (45–68 years. The median SPAP value in patients with PAH was 37.5 (35–45 mmHg. According to the echocardiographic findings, PAH was found in 14 (41.1% patients of HD group and in 6 (18.7% patients of PD group (P = 0.04. The median serum iron and hemoglobin was significantly lower in patients with PAH compared to those in patients with normal PAP (P < 0.05. Conclusion: Unexplained PAH seems to be more frequent in patients undergoing HD than patients in PD group. Moreover, hemoglobin and serum iron levels are lower in patients with PAH compared to those in normal PAP group.

    Full Text Available Methylenetetrahydrofolate Reductase (MTHFR is key enzyme in metabolism of homocysteine. Homozygotes for mutation (TT genotype have hyperhomocysteinemia, risk factor for atherosclerosis development. The aim of the study was to find out distribution of genotype frequencies of C677T MTHFR among patients on maintenance hemodialysis. Possible association of alleles and genotypes of C677T polymorphism of the MTHFR gene with age of onset, duration of dialysis and cause of kidney failure was studied also. Cross-sectional study includes 80 patients from Clinic of Hemodialysis KUCS in Sarajevo. In order to perform genotyping, isolated DNA was analyzed by RFLP-PCR and gel-electrophoresis. From total of 80 patients, 42.5% (n=24 were female, 57.5% (n=46 were male, mean age 54.59±1.78 years and duration of dialysis 79.92±6.32 months. Genotype distribution was: CC 51.2% (n=41, CT 37.5% (n=30 and TT 11.2% (n=9. Patients with wild-type genotype have longer duration of dialysis in month (87.1 ± 63.93 comparing to TT genotype patients (67.06 ± 39.3, with no statistical significance. T allele frequency was significantly higher in group of vascular and congenital cause of kidney failure (Pearson X2 =6.049, P<0.05 comparing to inflammation etiology group. Genotype distribution results are within the results other studies in Europe. Obtained results indicate that C677T polymorphism is not associated with onset, duration and cause of kidney failure in our hemodialysis population. There is an association of T allele of the MTHFR gene and vascular and congenital cause kidney failure.

    Abstract Background: Chronic kidney disease (CKD) and metabolic syndrome are characterized by overlapping disorders, including glucose intolerance, hypertension, dyslipidemia, and, in some cases, obesity. However, there are no specific criteria for the diagnosis of metabolic syndrome in CKD. Metabolic syndrome can also be associated with increased risk of mortality. Some traditional risk factors may protect dialysis patients from mortality, known as "reverse epidemiology." Metabolic syndrome might undergo reverse epidemiology. The objectives were to detect differences in frequency and metabolic characteristics associated with three sets of diagnostic criteria for metabolic syndrome, to evaluate the accuracy of insulin resistance (IR) and inflammation to identify patients with metabolic syndrome, and to investigate the effects of metabolic syndrome by three sets of diagnostic criteria on mortality in chronic hemodialysis patients. An observational study was conducted. Diagnostic criteria for metabolic syndrome proposed by National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III), International Diabetes Federation (IDF), and Harmonizing the Metabolic Syndrome (HMetS) statement were applied to 98 hemodialysis patients. The prevalence of metabolic syndrome was 51%, 66.3%, and 75.3% according to NCEP ATP III, IDF, and HMetS criteria, respectively. Diagnosis of metabolic syndrome by HMetS was simultaneously capable of revealing both inflammation and IR, whereas NCEP ATP III and IDF criteria were only able to identify IR. Mortality risk increased in the presence of metabolic syndrome regardless of the criteria used. The prevalence of metabolic syndrome in hemodialysis varies according to the diagnostic criteria used. IR and inflammation predict metabolic syndrome only when diagnosed by HMetS criteria. HMetS was the diagnostic criteria that can predict the highest risk of mortality.

    To study serum leptin level in chronic renal failure (CRF) hemodialysis patients and the relationship between serum leptin level and residue renal function, body composition, and indices of malnutrition, 31 end-stage CRF hemodialysis patients and 38 healthy people were enrolled. Serum leptin levels were detected by radioimmunoassay. BMI, %Fat and LBM were measured by bioelectrical impedance analysis device. Alb, Chol, Hgb, BUN, SCr and Ccr of the patients were also examined. Results showed that Serum leptin level in end-stage CRF hemodialysis patients was markedly higher than that in healthy controls (P 0.05). Conclusion: Hyperleptinemia existed in end-stage CRF hemodialysis patients and might cause the loss of LBM. The leptin level was not correlated with residue renal function, but it could reflect the fat content. However, serum leptin did not play a significant role in protein malnutrition in end-stage CRF hemodialysis patients

    Full Text Available 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.

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

    Full Text Available Epidemiological studies suggest various kinds of immune dysregulation in hemodialysis (HD patients. The aim of this study was to investigate the relationship between immune functions and nutritional status of HD patients. We studied 54 patients with ESRD on chronic HD, included 34 females and 20 males with mean age 46.6 ± 16.3 (18–77 years. We measured the height and dry weight of all patients. The BMI was calculated by dividing weight (kg by height squared ( m 2 . In all patients serum urea, creatinine, albumin, iron, cholesterol, triglyceride, CRP, IgG, IgM, IgA, CD4, CD8, CD19, CD16-56 lymphocytes were measured. Kt/V values were calculated according to DOQI guideline. In this study, a positive correlation between albumin, cholesterol, and triglyceride levels as nutritional parameters and immune functions in terms of total and subtype lymphocyte counts was observed. Further prospective studies are needed to determine the clinical importance of this finding and the appropriate means of measurement and effects of nutrition on immune function in hemodialysis patients.

    We performed this study to assess whether low dose spironolactone could be administered in hemodialysis (HD) patients with moderate to severe heart failure to improve cardiovascular function and reduce hospitalization without inducing hyperkalemia. We enrolled 16 chronic HD patients with moderate to severe heart failure and left ventricle ejection fraction :5 45%. In a double blinded randomized placebo controlled study, one group of 8 patients received 25 mg of spironolactone after each dialysis session within six months, and the rest received a placebo. Echocardiography was performed on all the patients to assess ejection fraction and left ventricular mass during 12 hours after completion of hemodialysis at the beginning and the end of study. Serum potassium was measured predialysis every 4 weeks. The mean ejection fraction increased significantly more in spironolactone group during the study period than in the placebo group (6.2 + - 1.64 vs. 0.83 + - 4.9, P0.046). The mean left ventricular mass decreased in the spironolactone group, but increased significantly in the placebo group during the period (-8.4 + - 4.72 vs. 3 + -7.97. 95%, P= 0.021). The incidence of hyperkalemia was not significantly increased in the study or controlled groups. In conclusion, we found in this study that administration of spironolactone in chronic HD patients with moderate to severe heart failure substantially improved their cardiac function and decreases left ventricular mass without development of significant hyperkalemia.

    The aim of this study was to evaluate the changes in salivary gland function in patients with chronic renal failure (CRF) undergoing hemodialysis. The group consisted of 23 patients with CRF (13 female, 10 male; mean age: 40{+-}13 yr) and 14 healthy control subjects (mean age: 40{+-}13 yr). All underwent dynamic salivary gland scintigraphy with gustatory stimulation. After intravenous administration of {sup 99m}Tc pertechnetate, first, perfusion images at 2 seconds per frame were acquired for 1 minute, then dynamic images at 1 minute per frame were acquired for 45 minutes. At 30 minutes after injection , 10 ml lemon juice was given for 15 minutes as a gustatory stimulus. We obtained time-activity curves derived from regions of interest centered over the four major salivary glands. The following functional indices were calculated for each gland: the time of maximum radioactivity (T{sub max}) for the prestimulated period, the time of minimum radioactivity (T{sub min}), as an indicator of velocity of secretion after stimulation, and the Lem E{sub 5}% value as an indicator of the secretion function. When the patients with CRF undergoing hemodialysis were compared to the controls, there were statistically significant differences in T{sub max}, T{sub min} and Lem E{sub 5}% values for bilateral parotid glands, and T{sub min} values for bilateral submandibular glands (p<0.05), there were no statistically significant differences in T{sub max} and Lem E{sub 5}% values for bilateral submandibular glands. There were also significant differences in T{sub max} and Lem E{sub 5}% values for bilateral parotid glands between mild oral problems and severe oral problems in patients with CRF (undergoing hemodialysis). In this study, prolonged T{sub max} and T{sub min} values, and decreased Lem E{sub 5}% values for parotid glands and prolonged T{sub min} values for submandibular glands on salivary scintigraphy pointed out decreased parenchymatous and excretory function in patients with

    Patients in end-stage renal disease often suffer from poor appetite, various comorbidities, and dietary restrictions. Despite regular hemodialysis, nutritional imbalances are frequently reported. Aiming to correlate nutritional status with food ingestion, a prospective study was done in an outpatient group. Stable patients undergoing chronic hemodialysis for at least 3 months (n=44) were investigated by dietary recall and standard anthropometric, biochemical, and bioimpedance determinations, including subjective and objective global assessment. The mean age of the group was 47.0+/-16.9 years, and 63.6% were men. Body mass index was 22.2+/-3.9 kg/m2 (mean+/-SD), calorie intake was 1471+/-601 kcal/day (20.7+/-6.7 kcal/kg/day), and protein ingestion was 74.3+/-16.6 g protein/day (1.2 g/kg/day). Dietary and clinical findings were correlated with nutritional indices by linear regression analysis. Malnutrition estimated by subjective global assessment was very common (>90%), despite the fact that body mass index and serum albumin were within an acceptable range in the majority of the population. Objective global assessment yielded roughly comparable numerical findings, with 6.8% being well nourished, 61.4% at nutritional risk or lightly undernourished, 29.6% moderately malnourished, and 2.3% severely malnourished. Total calorie intake was devoid of associations, but protein, carbohydrate, and lipid input positively correlated with triceps skinfold (P=.02). Lipid ingestion was the only marker directly associated with arm circumference, and it correlated with body mass index, as well as with total body fat (bioimpedance analysis) (Pprotein or total energy; 3) Despite its shortcomings, dietary recall was useful in the assessment of hemodialysis patients.

    Full Text Available One of the most important problems in patients on hemodialysis (HD is chronic malnutrition. This study is aimed to assess the prevalence of malnutrition using a subjective global assessment (SGA in HD patients referred to the Valie ASR Hospital, Arak, Iran. In this descriptive analysis study, 190 HD patients were selected with random sampling. SGA and anthropometric and biochemical measurements were assessed in all patients. Data were analyzed with the Chi-square and t-tests and Pearson correlation coefficient. P 50% of patients on maintenance HD had mild or moderate malnutrition. There was no case of severe malnutrition. Duration of dialysis treatment and some anthropometric indices (weight, BMI and MAC also showed a significant correlation with SGA score, which are important to determine the nutritional status of HD patients.

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

  2. Will Incremental Hemodialysis Preserve Residual Function and Improve Patient Survival?

    The progressive loss of residual renal function in peritoneal dialysis patients is associated with increased mortality. It has been suggested that incremental dialysis may help preserve residual renal function and improve patient survival. Residual renal function depends upon both patient related and dialysis associated factors. Maintaining patients in an over-hydrated state may be associated with better preservation of residual renal function but any benefit comes with a significant risk of cardiovascular consequences. Notably, it is only observational studies that have reported an association between dialysis patient survival and residual renal function; causality has not been established for dialysis patient survival. The tenuous connections between residual renal function and outcomes and between incremental hemodialysis and residual renal function should temper our enthusiasm for interventions in this area.

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

    Background: It was shown that nonoxidized PTH (n-oxPTH) is bioactive, whereas the oxidation of PTH results in a loss of biological activity. Methods: In this study we analyzed the association of n-oxPTH on mortality in hemodialysis patients using a recently developed assay system. Results......: Hemodialysis patients (224 men, 116 women) had a median age of 66 years. One hundred seventy patients (50%) died during the follow-up period of 5 years. Median n-oxPTH levels were higher in survivors (7.2 ng/L) compared with deceased patients (5.0 ng/L; P = .002). Survival analysis showed an increased survival...... in the highest n-oxPTH tertile compared with the lowest n-oxPTH tertile (χ(2), 14.3; P = .0008). Median survival was 1702 days in the highest n-oxPTH tertile, whereas it was only 453 days in the lowest n-oxPTH tertile. Multivariable-adjusted Cox regression showed that higher age increased odds for death, whereas...

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

    Conclusion: The results showed that from the viewpoint of the participants, the concept of support consisted of psychological support, social support, accompanying the patient, and spiritual support. Hence, it can be concluded that this concept should be considered in healthcare planning, in order to improve the health and quality of life of these patients and their adaptation to the disease and its treatment process.

    Full Text Available Patients with end-stage renal disease (ESRD experience higher rates of hospitalisation, cardiovascular events, and all-cause mortality and are more likely to require admission to the intensive care unit (ICU than patients with normal renal function. Sepsis and cardiovascular diseases are the most common reasons for ICU admission. ICU mortality rates in patients requiring chronic hemodialysis are significantly higher than for patients without ESRD; however, dialysis patients have a better ICU outcome than those with acute kidney injury (AKI requiring renal replacement therapy suggesting that factors other than loss of renal function contribute to their prognosis. Current evidence suggests, the longer-term outcomes after discharge from ICU may be favourable and that long-term dependence on dialysis should not prejudice against prompt referral or admission to ICU.

    2017-01-01

    Full Text Available Hemodialysis (HD patients are at high risk for all-cause mortality and cardiovascular events. In addition to traditional risk factors, excessive oxidative stress (OS and chronic inflammation emerge as novel and major contributors to accelerated atherosclerosis and elevated mortality. OS is defined as the imbalance between antioxidant defense mechanisms and oxidant products, the latter overwhelming the former. OS appears in early stages of chronic kidney disease (CKD, advances along with worsening of renal failure, and is further exacerbated by the HD process per se. HD patients manifest excessive OS status due to retention of a plethora of toxins, subsidized under uremia, nutrition lacking antioxidants and turn-over of antioxidants, loss of antioxidants during renal replacement therapy, and leukocyte activation that leads to accumulation of oxidative products. Duration of dialysis therapy, iron infusion, anemia, presence of central venous catheter, and bioincompatible dialyzers are several factors triggering the development of OS. Antioxidant supplementation may take an overall protective role, even at early stages of CKD, to halt the deterioration of kidney function and antagonize systemic inflammation. Unfortunately, clinical studies have not yielded unequivocal positive outcomes when antioxidants have been administered to hemodialysis patients, likely due to their heterogeneous clinical conditions and underlying risk profile.

    Full Text Available The main cause of death among dialysis is cardiovascular. The development of atherosclerosis involves several classical risk factors such as diabetes mellitus, hypertension and dyslipidemia. Knowing their characteristics allows planning therapeutic actions aimed at reducing mortality. The aim was to characterize clinically a sample of HD patients. Forty-nine patients on HD for at least 6 months were included. Individuals with malignant disease, active inflammation, in use of omega-3 oil or anticoagulants were excluded. Clinical data were collected from medical records. Albumin, urea, creatinine, total cholesterol, triglycerides (TG, phosphorus and potassium were measured. The average age of patients (27 men and 22 women was 49.9 ± 14.3 years. The mean duration of the HD was 41.8 ± 35.9 months. About 50% were diabetic and 100% were hypertensive. Dyslipidemia was observed in 47% of patients and 51% had hypoalbuminaemia. Hyperphosphatemia was found in 77.5% and hyperkalemia was observed in 43% of patients. Negative association between TG and urea was found (r = -0.33, p = 0.03. The patients treated for a longer time for HD showed higher levels of phosphate. It is evident the presence of metabolic imbalance in patients treated for HD. Therapeutic interventions such as supplementation with omega-3 fatty acids may be important in reducing morbidity and mortality in this population.

    Full Text Available Introduction. Chronic renal failure and dialysis are complicated situations that affect on somatic and mental status of patients. In this study, relation between stress, renal diseas, dialysis and mental disorders was determined. Methods. In a case control study in Noor hospital"s dialysis ward (affiliated to Isfahan University of Medical Sciences and Health Services the mental status of 30 end stage renal disease (ESRD patients were compaired with well matched control group by MMPI. Results. Hypochondriasis (Hs, depression (D, hysteria (Hy psychastenia (Pt and schizophrenia (Sc were observed in ESRD patients more than controls (P < 0.05. Means of sociopathy (Pd, paranoia (Pa and hypomania (Ma had no difference between groups (P > 0.05. Realy sadness and dysphoria, rumintion with illness, obsession, anxiety, compulsion, impaired process of thinking, isolation tendency and odd sensation in patients were more than control group (P < 0.05. Discussion. Chronic diseases have psychological complication and as a stress must cope and adjust with it. So, these patients and their families must be educated about coping mechanism. When the patients and their families have good coping mechanism, they would be able tolerate these streses.

    Full Text Available Aim: The aim of the present study is to determine whether there are statistically differences between hemodialysis patients and control (healthy groups according to level of serum cadmium (Cd, total triiodothyronine (T3 and total thyroxine (T4 and adrenocorticotropin hormone (ACTH, and besides whether there are any correlation coefficients of trace element with thyroid profiles, ACTH in these groups. Material and Methods:The study included 47 hemodialysis patient who were dialyzed three times a week and each session was at least 4 hours. The duration of dialysis range were 2-16 yr. This group called as a “Hemodialyis group”. Blood samples were taken before (pre-hemodialysis and after (post-hemodialysis hemodialysis session. “Control group” included 23 healthy volunteers with no medical problem. In control group, samples were taken after 10 hour fasting. Results: Levels of total T3 were higher in group of control than the levels of pre-hemodialysis and post-hemodialysis (p≤0.001. Total T3 levels were lower in pre-hemodialysis (p≤0.05 than those of post-hemodialysis. The highest level of total T4 and lowest level of Cd were in control group and these parameters were statistically different from the pre-hemodialysis (respectively p≤0.001, p≤0.01. We did not determine any significant differences between all groups according to data of ACTH levels. Discussion: We suggest that analyzing the levels of Cd may be useful for the hemodialysis patients. But, we did not determine a significant association between Cd and thyroid profiles and ACTH levels.

    The aim of the present study was to evaluate the alteration in plasma immunoreactive insulin (IRI) concentrations due to hemodialysis (HD) treatment by using three types of membranes in diabetic HD patients. We recruited 20 outpatients on maintenance HD with diabetes for this crossover study. HD was performed using membranes made of cellulose triacetate (CTA), polyester-polymer alloy (PEPA), and polysulphone (PS). These membranes were used for 2 weeks (6 HD sessions) in each patient in a randomized order decided by drawing lots. Blood samples were obtained at the beginning and end of the HD session from the blood tubing at the arterial (A) site. At 60 min after the initiation of dialysis, blood samples were obtained from the blood tubing at both the A and venous (V) sites of the dialyzer. The plasma IRI levels decreased significantly at the sites an hour after initiating HD in all membranes. The clearance of IRI was significantly higher in the case of the PS membrane when compared with the CTA and PEPA membranes. It was concluded that plasma insulin is cleared by HD, and the rate differs for each membrane. Plasma insulin clearance with the PS membrane is higher than that with the PEPA and CTA membranes.

    Full Text Available Background: Achievement of normal volume status is crucial in hemodialysis (HD, since both volume expansion and volume contraction have been associated with adverse outcome and events. Objectives: The objectives of this study are to assess the prevalence of fluid volume expansion and depletion and to identify the best clinical parameter or set of parameters that can predict fluid volume expansion in HD patients. Design: This study is cross-sectional. Setting: This study was conducted in three hemodialysis units. Patients: In this study, there are 194 HD patients. Methods: Volume status was assessed by multifrequency bio-impedance spectroscopy (The Body Composition Monitor, Fresenius prior to the mid-week HD session. Results: Of all patients, 48 % ( n = 94 were volume-expanded and 9 % of patients were volume-depleted ( n = 17. Interdialytic weight gain was not different between hypovolemic, normovolemic, and hypervolemic patients. Fifty percent of the volume-expanded patients were hypertensive. Paradoxical hypertension was very common (31 % of all patients; its incidence was not different between patient groups. Intradialytic hypotension was relatively common and was more frequent among hypovolemic patients. Multivariate regression analysis identified only four predictors for volume expansion (edema, lower BMI, higher SBP, and smoking. None of these parameters displayed both a good sensitivity and specificity. Limitations: The volume assessment was performed once. Conclusions: The study indicates that volume expansion is highly prevalent in HD population and could not be identified using clinical parameters alone. No clinical parameters were identified that could reliably predict volume status. This study shows that bio-impedance can assist to determine volume status. Volume status, in turn, is not related to intradialytic weight gain and is unable to explain the high incidence of paradoxical hypertension.

    To characterize the nutritional status of renal failure patients and its relationship with hemodialysis adequacy measured by Kt/V, a study was carried out with a population of 44 adult patients with renal failure and mean age 51+/-15 years. Anthropometric data, such as dry weight, height, arm circumference, triceps skinfold thickness, mid-arm muscle circumference, and body mass index were assessed, and biochemical tests were conducted for urea, potassium, creatinine, serum albumin, and phosphorus levels, in addition to hemogram and quarterly urea reduction rate average (Kt/V). In order to evaluate calorie intake, a dietary questionnaire on habitual daily food ingestion was administered, taking into consideration the hemodialysis date. The patients were divided into 2 separate groups for the statistical analysis, with 50% of the patients in each group: A (Kt/V1.2). The data were tabulated as mean and standard deviation, with differences tested by Student's t test. The correlations between variables were established by the coefficient p of Pearson. Most of the patients (43%) were considered eutrophic, based on the BMI, and presented inadequate calorie intake, corresponding to 88.5+/-24% (30.8 kcal/kg actual weight) of the total energy required and adequate protein intake, reaching 109.9+/-40% of the recommended daily allowance (1.24 g/kg of actual weight). There was a correlation of Kt/V with anthropometric parameters such as body mass index, arm circumference, and mid-arm muscle circumference. The biochemical parameters related to dialysis adequacy were albumin, ferritin, and urea (predialysis). Well-dialyzed patients presented better levels of serum albumin. There was an influence of gender and age on correlations of the analyzed variables. Female and younger patients presented better dialysis adequacy. The dialysis adequacy was related to the nutritional status and influenced by the protein intake and body composition. Gender and age had an important influence in

    Full Text Available "nBackground: The annual amount of mortality in ESRD exceeds the expectation and represents the recent evidences of the inflammation as its etiology. The etiology of inflammation is not clearly known. Chronic inflammation is a dominant occurrence of ESRD which increases the risk of atherosclerosis, malnutrition and peripheral vascular disease. Inflammatory responses are orchestrated by cytokines. Some of the proinflammatory cytokines like IL-6 have a crucial role in this phenomenon. The IL-6 and its receptor activity is up regulated in ESRD patients and the increased level of IL-6 predicts cardiovascular mortality and morbidity in normal and CRF patients. This study devotes itself to determining the serum level of IL-6 and factors affecting it in patients undergoing chronic hemodialysis in Imam Khomeini Hospital which can represent the Iranian Society. By identifying factors affecting the serum level of IL-6 and high-risk patients we can provide treatment possibilities, a decrease in mortality and an improvement in its prognosis.

    BP variability (BPV) is an important predictor of outcomes in the general population, but its association with clinical outcomes in hemodialysis patients is not clear. We identified 11,291 patients starting dialysis in 2003–2008 and followed them through December 31, 2008 (median=22 months). Predialysis systolic BPV was assessed over monthly intervals. Outcomes included factors associated with BPV, mortality (all-cause and cardiovascular), and first cardiovascular event (cardiovascular death or hospitalization). Patients' mean age was 62 years, 55% of patients were men, and 58% of patients were white. Modifiable factors associated with higher BPV included obesity, higher calcium–phosphate product levels, and lower hemoglobin concentration; factors associated with lower BPV included greater fluid removal, achievement of prescribed dry weight during dialysis, higher hemoglobin concentration, and antihypertensive regimens without β-blockers or renin-angiotensin system blocking agents. In total, 3200 deaths occurred, including 1592 cardiovascular deaths. After adjustment for demographics, comorbidities, and clinical factors, higher predialysis BPV was associated with increased risk of all-cause mortality (hazard ratio [HR], 1.18; 95% confidence interval [95% CI] per 1 SD increase in BPV, 1.13 to 1.22), cardiovascular mortality (HR, 1.18; 95% CI, 1.12 to 1.24), and first cardiovascular event (HR, 1.11; 95% CI, 1.07 to 1.15). Results were similar when BPV was categorized in tertiles and patients were stratified by baseline systolic BP. In summary, predialysis systolic BPV is an important, potentially modifiable risk factor for death and cardiovascular outcomes in incident hemodialysis patients. Studies of BP management in dialysis patients should focus on both absolute BP and BPV. PMID:24385593

Envejecimiento (décadas y tabaquismo estaban asociados a aumento de la EIM (odds ratio ajustado [aOR] = 3,4, p BACKGROUND: Patients on hemodialysis present an increased risk of cardiovascular death. Intimal media thickness (IMT and presence of arterial calcifications are well-known risk factors for cardiovascular death in hemodialysis patients. OBJECTIVE: To assess the prevalence of IMT and arterial calcifications in HD patients and to correlate image findings with clinical and laboratory data. METHODS: Cross-sectional study involving 75 patients on dialysis for >12 months. Patients underwent B-mode ultrasound scan (US for determination of IMT of the distal third of the common carotid arteries. Arterial calcifications were assessed by US of carotids, femoral and tibial arteries, and labeled positive if calcification was found in any arterial site. RESULTS: Patients were 52±13 years old, 57% were males and 16% were diabetics. IMT > 0.9 mm was found in 57% of cases and arterial calcifications at US in 48%. Aging (decades and smoking were associated with both increased IMT (adjusted odds ratio [aOR] = 3.4, p < 0.001; aOR = 4.4, p = 0.045, respectively and presence of vascular calcifications (aOR = 3.0, p < 0.001; aOR = 6.8, p = 0.011, respectively. High intact parathyroid hormone levels (per each 100 pg/ml were significantly associated with increased IMT (aOR = 1.7, p = 0.021, but not with vascular calcification. In contrast, Diabetes and time on dialysis (years were significant determinants for calcifications at US (aOR = 15.0, p = 0.009; aOR = 1.39, p = 0.020, but not for increased IMT. CONCLUSION: Increased IMT and calcifications at US are common findings in hemodialysis patients. Aging and smoking are consistent determinants for both image alterations. Parathyroid hormone elevation is associated with increased IMT. Diabetes and time on dialysis

    Full Text Available Obstruction of blood flow in the superior vena cava (SVC results in symptoms and signs of SVC syndrome. SVC obstruction can be caused either by invasion or external compression of the SVC by contagious pathologic processes involving the right lung, lymph nodes, and other mediastinal structures, or by thrombosis of blood within the SVC. Occasionally, both mechanisms co-exist. We hereby report a case of a 28-year-old male, Saudi patient who was diagnosed with end-stage renal disease and was maintained on regular hemodiaysis via right jugular vein dual lumen catheter for ten months. Three years later, the patient presented with signs and symptoms suggestive of SVC obstruction that was successfully managed with SVC stenting.

    Among people with essential hypertension, ambulatory BP measurement is superior to BP obtained in the clinic in predicting cardiovascular outcomes. In part, this is because it can detect white-coat hypertension and masked hypertension. Whether the same is true for hemodialysis patients is not known. Using a threshold of 140/80 mmHg for median midweek dialysis-unit BP and 135/85 mmHg for 44-hour ambulatory BP, we defined four categories of BP: sustained normotension (SN), white-coat hypertension (WCH), masked hypertension (MHTN), and sustained hypertension (SHTN). Among 355 long-term hemodialysis patients, the prevalence of SN was 35%, WCH 15%, MHTN 15%, and SHTN 35%. Over a mean follow-up of 29.6 (SD 21.7) months, 102 patients died (29%), yielding a crude mortality rate of 121/1000 patient-years. Unadjusted and multivariate-adjusted analyses showed increasing all-cause mortality with increasing severity of hypertension (unadjusted hazard ratios from SN, WCH, MHTN, SHTN: 1, 1.12, 1.70, 1.80, respectively [P for trend hypertension population, MHTN and WCH have prognostic significance. The prognostic value of BP obtained in the dialysis unit can be refined with ambulatory BP monitoring.

    Infectious endocarditis (IE), a complication that is both cardiac and infectious, occurs frequently and is associated with a heavy burden of morbidity and mortality in chronic hemodialysis patients (CHD). About 2-6% of chronic hemodialysis patients develop IE and the incidence is 50-60 times higher among CHD patients than in the general population. The left heart is the most frequent location of IE in CHD and the different published series report a prevalence of left valve involvement varying from 80% to 100%. Valvular and perivalvular abnormalities, alteration of the immune system, and bacteremia associated with repeated manipulation of the vascular access, particularly central venous catheters, comprise the main factors explaining the left heart IE in CHD patients. While left-sided IE develops in altered valves in a high-pressure system, right-sided IE on the contrary, generally develops in healthy valves in a low-pressure system. Right-sided IE is rare, with its incidence varying from 0% to 26% depending on the study, and the tricuspid valve is the main location. Might the massive influx of pathogenic and virulent germs via the central venous catheter to the right heart, with the tricuspid being the first contact valve, have a role in the physiopathology of IE in CHD, thus facilitating bacterial adhesion? While the physiopathology of left-sided IE entails multiple and convincing mechanisms, it is not the case for right-sided IE, for which the physiopathological mechanism is only partially understood and remains shrouded in mystery.

    Full Text Available Depression is a mental disorder with a high prevalence among patients with end stage renal disease (ESRD. It is reported that depression afflicts approximately 20-30% of this patient population, being associated, amongst other, with high mortality rate, low adherence to medication and low perceived quality of life. There is a variety of medications known to be effective for the treatment of depression but due to poor adherence to treatment as well as due to the high need for medications addressing other ESRD comorbidities, depression often remains untreated. According to the literature, depression is under-diagnosed and undertreated in the majority of the patients with chronic kidney disease. In the current review the main pharmacological and non-pharmacological approaches and research outcomes for the management of depressive symptoms in hemodialysis patients are discussed.

    Disorder of blood lipids plays an important role in atherosclerosis progress in patients ongoing chronic haemodialysis (PCHD). These patients have specific features of blood lipids with increment of triglycerides and decrement of HDL-cholesterol. Phenotype of lipid disorder in PCHD is mostly type IV according to Fredrickson (30%), and IIA and IIB fenotypes are less frequent. About 9% of lipid disorders in PCHD are isolated increase of Lp(a). Main reason of hypertriglyceridemia in PCHD is attenuated metabolism of VLDL-cholesterol because of lipoprotein lipasis inhibition. There are changes in lipoproteins quality, specially changes in LDL particle have atherogenic potential. Renal dyslipidemia treatment must be vigorous in the early stages of renal insufficiency. Treatment can be dietary measures (specially omega-3-fatty acids), statins, gemfibrozil, intravenous L-carnitin and bicarbonate given per os. Haemodialysis modifications such as highflux haemodialysis, low molecular weight heparin, vitamin E coated dialyzers and LDL-apheresis in extreme cases have important role in renal dyslipidemia treatment.

    Nonselective vitamin D receptor activators (VDRA), such as calcitriol and alfacalcidol, have been successfully used in the treatment of secondary hyperparathyroidism (SHPT) in hemodialysis. Despite their beneficial effects on the control of serum PTH levels, their use has been limited by intolerance (development of hypercalcemia and hyperphosphatemia with consecutive cardiovascular toxicity). Apart from becoming intolerant, in 20-30 % of patients who use nonselective VDRA, serum PTH levels do not decrease appropriately despite increasing doses of these agents. These patients are considered calcitriol-resistant patients. Thus, calcitriol resistance and intolerance are two sides of the same coin: active vitamin D failure. Despite the clinical relevance of active vitamin D failure, definitions of resistance and intolerance are imprecise and have varied over time. More selective VDRA claim to produce less hypercalcemia and hyperphosphatemia and could help clinicians to overcome intolerance. Also, some studies have also shown that paricalcitol can be even useful in resistant patients. Significant limitations of iPTH as a reliable and useful clinical biomarker have been increasingly appreciated. There is evidence that intact PTH concentration must differ by 72 % between any two measurements before it can be considered a significant change. VDR polymorphisms could be involved in the development of SHPT in CKD patients. Interestingly, a higher incidence of the b allele of the VDR BsmI gene variant has been shown to be present in SHPT. The BsmI genotype can also affect the response of hemodialysis to IV calcitriol. A challenge for the future will be to establish biomarkers such as laboratory determinations or ultrasound findings that can help us to early identify those patients who will not respond appropriately to calcitriol or exhibit intolerable side effects .

    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.

    The state of hydration affects the outcomes of chronic dialysis. Bioelectrical impedance analysis (BIA) provides estimates of body water (V), extracellular volume (ECFV), and fat-free mass (FFM) that allow characterization of hydration. We compared single-frequency BIA measurements before and after 14 hemodialysis sessions in 10 Nigerian patients (6 men, 4 women; 44+/-7 years old) with clinical evaluation (weight removed during dialysis, presence of edema) and with estimates of body water obtained by the Watson, Chertow, and Chumlea anthropometric formulas. Predialysis and postdialysis values of body water did not differ between BIA and anthropometric estimates. However, only the BIA estimate of the change in body water during dialysis (-0.8+/-2.9 L) did not differ from the corresponding change in body weight (-1.3+/-3.0 kg), while anthropometric estimates of the change in body water were significantly lower, approximately one-third of the change in weight. Bioelectrical impedance analysis correctly detected the intradialytic change in body water content (the ratio V/Weight) in 79% of the cases, while anthropometric formula estimates of the same change were erroneous in each case. Compared with patients with clinical postdialysis euvolemia (n=7), those with postdialysis edema (n=5) had higher values of postdialysis BIA ratios V/FFM (0.77+/-0.01 vs. 0.72+/-0.03, phydration in patients on chronic hemodialysis. In contrast, BIA provides estimates of hydration agreeing with clinical estimates in the same patients, although it tends to underestimate body water and extracellular volume in patients with large collections of fluid in central body cavities.

    Headache is among most frequently encountered neurological symptom during hemodialysis (HD), but still under investigated in peritoneal dialysis (PD) patients. The aim of this study was to assess the incidence and clinical characteristics of dialysis headache (DH) in HD and PD patients. A total of 409 patients (91 on PD and 318 on HD) were interviewed using a structured questionnaire, designed according to the diagnostic criteria of the International Headache Classification of Headache Disorders from 2004. Patients with DH underwent a thorough neurological examination. DH was reported by 21 (6.6%) HD patients and 0 PD patients. PD patients had significantly lower serum sodium, potassium, calcium, phosphate, urea and creatinine, calcium-phosphate product, and diastolic blood pressure than HD patients. HD patients had significantly lower hemoglobin compared to PD patients. Primary renal disease was mostly parenchymal in HD patients, and vascular in PD patients. DH appeared more frequently in men, mostly during the third hour of HD. It lasted less than four hours, was bilateral, non-pulsating and without associated symptoms. Biochemical alterations may be implicated in the pathophysiology of DH. Specific features of DH might contribute to better understanding of this secondary headache disorder.

    Full Text Available Full training according to the information needs of patients reduces health care costs and increases the quality of care. The present study was conducted aims to prioritize the preferences of hemodialysis patients in acquisition of health information to be able to provide training according to these preferences and their prioritization after achieving them. This study was a descriptive cross-sectional one which was conducted on all hemodialysis patients who visited Kowsar Hospital in Semnan within the year 2014-2015. Data collecting tool was researcher-made questionnaire which assessed physical information needs of patients in four areas of nutrition, energy, pain and discomfort, sleep and rest. Data were analyzed by SPSS software version 16 using the descriptive statistics.71 hemodialysis patients participated in this study. 68.6%, 50.7%, 42.6% and 46.7% of patients expressed acquisition information regarding hematopoietic foods, how to increase mobility, how to relieve itching during dialysis and mental activities before sleep as their first priorities, respectively. The results of this study showed that hemodialysis patients need to know what kinds of information in the field of physical problems. To facilitate adaptation and selfcare of patients, providing information and training based on the real needs of patients will be helpful.

    Patients with renal failure undergoing hemodialysis often have muscle cramps during and after the dialysis therapy. Muscle cramps are defined as the sudden onset of a prolonged involuntary muscle contraction accompanied with severe pain, resulting in early termination of a HD session and inadequate dialysis. The etiology of the cramps is unknown and effective anti-cramp medicine is not available. We have hypothesized that water-soluble vitamins are deficient in HD patients. Accordingly, we administrated biotin to 14 patients who had frequent muscle cramps during HD sessions. Oral administration of 1 mg/day biotin promptly reduced the onset and the severity of cramps in 12 patients both during and after HD. Then, the plasma biotin levels were measured by an enzyme-linked immunosorbent assay method (ELISA) in HD patients, including 14 patients with cramps and 13 patients without cramps, and 11 healthy volunteers. Plasma biotin levels were elevated in 27 HD patients at baseline compared with healthy volunteers [451 (377 - 649) vs. 224 (148 - 308) ng/l, median (lower-upper quartiles); p cramp patients, the biotin levels were significantly higher in biotin-ineffective 7 patients than biotin-effective 7 patients [1,064 (710 - 1,187) vs. 445 (359 - 476) ng/l; p cramps regardless of their elevated plasma biotin levels.

    We sought to determine whether the MNA (Mininutritional Assessment) would be an effective tool for assessing the nutritional status of patients undergoing hemodialysis. Purposive sampling. Two hospital-managed hemodialysis centers in central Taiwan. Subjects were 95 ambulatory patients older than 40 years without acute diseases or infections who had received hemodialysis treatment at the center for longer than 30 days. Each subject was interviewed with a structured questionnaire to elicit basic personal data and health- and lifestyle-related information and answered questions on the Council on Nutrition Appetite Questionnaire and MNA. Serum biochemical data were obtained from their routine measurement. The nutritional status of each subject was graded with two modified MNA versions. MNA-TI adopted population-specific anthropometric cut-points, and MNA-TII further had the body mass index question deleted from the scale and question scores adjusted but maintained the same 30 total points. Based on the strength of correlation with the key nutrition-related parameters including appetite status, serum creatinine, percent weight loss, hospital length of stay, number of prescribed drugs, and hemodialysis time, both modified MNA versions reflected the nutritional status of Taiwanese hemodialysis patients better than the Council on Nutrition Appetite Questionnaire. Serum albumin did not reflect nutritional status well in these hemodialysis patients. MNA-TI predicted 26.4% and MNA-TII predicted 29.5% of hemodialysis patients were either malnourished or at risk of malnutrition. Both versions of the modified MNA are effective in assessing the nutritional status of hemodialysis patients. MNA-TII without body mass index is a significant improvement for hemodialysis patients because body weights fluctuate significantly between dialysis sessions.

    One-size-fits-all protocol-based approaches to anemia management with erythropoiesis-stimulating agents (ESAs) may result in undesired patterns of hemoglobin variability. In this single-center, double-blind, randomized controlled trial, we tested the hypothesis that individualized dosing of ESA improves hemoglobin variability over a standard population-based approach. We enrolled 62 hemodialysis patients and followed them over a 12-month period. Patients were randomly assigned to receive ESA doses guided by the Smart Anemia Manager algorithm (treatment) or by a standard protocol (control). Dose recommendations, performed on a monthly basis, were validated by an expert physician anemia manager. The primary outcome was the percentage of hemoglobin concentrations between 10 and 12 g/dl over the follow-up period. A total of 258 of 356 (72.5%) hemoglobin concentrations were between 10 and 12 g/dl in the treatment group, compared with 208 of 336 (61.9%) in the control group; 42 (11.8%) hemoglobin concentrations were hemoglobin concentrations were >12 g/dl in the treatment group compared with 46 (13.4%) in the control group. The median ESA dosage per patient was 2000 IU/wk in both groups. Five participants received 6 transfusions (21 U) in the treatment group, compared with 8 participants and 13 transfusions (31 U) in the control group. These results suggest that individualized ESA dosing decreases total hemoglobin variability compared with a population protocol-based approach. As hemoglobin levels are declining in hemodialysis patients, decreasing hemoglobin variability may help reduce the risk of transfusions in this population.

    Anemia is common in hemodialysis patients, and improvement in anemia management is possible with the implementation of continuous quality improvement (CQI) programs. The aim of this study is to improve anemia management in chronic hemodialysis patients using CQI. Ninety hemodialysis patients in our single center were enrolled in the study. The patients were followed up from January 2004 to October 2005. The CQI team-oriented approach was driven by a process called the 'FOCUS-PDCA cycle plan' (find, organize, clarify, uncover, start, plan, do, check and act). Hemoglobin (Hb), serum ferritin and transferrin saturation were monitored periodically. By implementation of the CQI program, the proportion of patients with Hb >or=110 g/l increased from 42.2 to 60.0% (p method in the management of anemia in hemodialysis patients. Copyright 2006 S.

      Protein-energy wasting (PEW) is very common in patients with chronic kidney disease and those undergoing maintenance dialysis. Reduced handgrip strength is associated with PEW and considered as a reliable nutritional parameter that reflects loss of muscle mass. This study aimed to evaluate the handgrip strength and its relationship with the Malnutrition-Inflammation Score (MIS) among Iranian dialysis patients. The study population consisted of 83 randomly selected hemodialysis patients from the dialysis centers in Kerman, Iran. Handgrip strength was measured using a dynamometer according to the recommendations of the American Society of Hand Therapists. All the patients were interviewed and the MIS of the patients were recorded.  Results. The PEW was prevalent in Kerman hemodialysis patients, with 83% and 17% having mild and moderate PEW based on MIS, respectively. Handgrip strength was significantly associated with age, sex, height, weight, and diabetes mellitus. After adjustment for age, handgrip strength was significantly associated with nutritional assessment markers on the basis of the MIS. Handgrip strength can be incorporated as a reliable tool for assessing nutrition status in clinical practice. However, further research is needed to determine the reference values and cutoff points both in healthy people and in hemodialysis patients to classify muscle wasting.

    The adverse effects of yellow fever (YF) vaccine in dialysis patients are not well known. There is concern about the risks and benefits of the vaccine in immunocompromised patients living in endemic areas, particularly given the risk of resurgence of urban YF with the spread of Aedes aegypti mosquitoes. The purpose of this study was to assess the coverage and safety of YF vaccine in chronic dialysis patients. A cross-sectional study of 130 chronic dialysis patients was performed. Data were collected on clinical characteristics and YF vaccine status. Patients not vaccinated against YF or without a booster vaccination within the last 10 years were referred to receive the vaccine, and adverse effects were monitored. Previous vaccination was verified in 44 patients within the last 10 years and in 26 patients at more than 10 years ago, with no mention of adverse effects. Thirty-six patients had never been vaccinated and 24 had an unknown vaccination status. Of the total 86 patients referred for immunization, 45 actually received the YF vaccine, with 24.4% experiencing mild local adverse effects and 4.4% experiencing fever. No serious adverse effects attributable to YF vaccine were observed (anaphylaxis, neurological or viscerotropic disease). YF vaccine coverage among hemodialysis patients is low, and the vaccine appeared to be safe in this population with a small sample size. Copyright © 2016 The Authors. Published by Elsevier Ltd..

    Midodrine is an alpha-agonist that causes peripheral vasoconstriction, resulting in increased blood pressure. It has been reported to be safe and effective in patients with end stage renal disease (ESRD) and is widely used for hemodialysis-associated hypotension. We report a case report of midodrine-induced ischemia in a patient on hemodialysis and review the literature relating to the safety of midodrine in patients with end stage renal disease.

    Patients with end-stage renal disease are required to limit fluid and salt intake. We examined illness representations [common-sense model (CSM)] among a sample of hemodialysis (HD) patients, investigating whether fluid-adherent patients held illness representations different from those of nonadherent patients. We also explored the utility of illness perceptions in predicting fluid nonadherence after controlling for clinical parameters, including residual renal function (KRU). Illness perceptions were assessed [Revised Illness Perception Questionnaire (IPQ-R)] in 99 HD patients. Clinical parameters were collected and averaged over a 3-month period prior to and including the month of IPQ-R assessment. Depression scores, functional status, and comorbidity were also collected. Fluid nonadherence was defined using interdialytic weight gain (IDWG) and dry weight (ideal weight). Patients in the upper quartile of percent weight gain were defined as nonadherent (IDWG> or =3.21% dry weight). Nonadherent patients had timeline perceptions significantly lower than those of adherent patients. Logistic regression models were computed in order to identify predictors of fluid nonadherence. After several demographic and clinical variables, including age, gender, and KRU, had been controlled for, lower consequence perceptions predicted nonadherence. Illness representations appear to predict fluid nonadherence among HD patients. Extending the CSM to investigate specific perceptions surrounding treatment behaviors may be useful and merits attention in this setting. 2010 Elsevier Inc. All rights reserved.

    nutritional status at 3 and 6 months. To assess the nutritional status, we used dry weight (DW), body mass index (BMI), skinfold caliper measurement (result is correlated with total body fat, FAT), and common laboratory indicators of nutritional status (serum albumin and cholesterol). RE- SULTS: Analyzing the efficiency of skinfold thickness measurement with caliper, we found that the FAT obtained by caliper showed a statistically significant positive correlation with clinical indicators of nutritional status, and with BMI (r = 0.364, p nutritional status, including serum albumin (r = 0.299, p = 0.01) and cholesterol (r = 0.225, p = 0.002). There was no statistically significant correlation between the duration of RRT and FAT (p = NS). In clinical practice, as well as for regular evaluation of nutritional status, it is important that the method we used proved efficient, precise, relatively fast and posing less economic burden. From our experience, the measurement of skinfold with caliper is an applicable, relatively quick and inexpensive method for regular assessment of nutritional status in patients treated with hemodialysis proce- dures. Therefore, all patients treated with RRT should undergo nutritional screening and expert help should be available from dietitians or nutritional support teams in order to identify this problem properly in its early stage and to reduce its high prevalence.

    Full Text Available Protein energy wasting (PEW is a prevalent problem among hemodialysis patients. Lack of adherence to dietary principle based conventional diet charts often fail to satisfy the nutritional requirements of the patients. We studied the effect of simple nutritional training and empowerment of the patients to formulate their own dietary menu in nutritional parameters of hemodialysis patients in 68 stable non diabetic End stage renal disease (ESRD patients who are on maintenance hemodialysis. The factors which otherwise can affect the nutritional status like sepsis, malignancy,tuberculosis were excluded. At the beginning patient's baseline nutritional status was assessed by anthropometric measurements, Subjective Global Assessment and serum albumin level. Body composition was assessed by linear regression equation (Durin-Womersley and Siri equation. The patients were divided in two comparable groups (Group-A&B. In group A patients were prescribed individualized dietary prescription; based on their nutritional allowance as per KDOQI guideline. In Group-B the patients were initially made familiar with the dietary principals of the commonly consumed food. Then they were trained by renal nutritionist by study material, visual aid, and proportional food models and one to one discussion to formulate a dietary menu, by these they were empowered to formulate their own dietary menu. They were constantly assisted when faced any problem. In both the group the nutritional parameters were reassessed after three months of intervention. The results were analyzed statistically. There was statistically significant mean increment in the fat free mass index in GroupB[0.8%(Gr.-AVs1.0%(Gr.-B,(p<0.05], the mean increment in the serum albumin in the GroupB was also significantly higher than GroupA[(0.6gm/dl(Gr.A Vs 0.9 gm/dl(Gr.B, p<0.0].Compared to Group-A there was statistically favorable anthropometric changes in Group-B.

    Dialysis patients have high mortality rate and the leading cause of death is cardiovascular disease. Uremic cardiomyopathy differs from that due to conventional atherosclerosis, where cardiovascular changes result in ineffective circulation and lead to tissue ischemia. Modern dialysis has significant limitations with fluid management probably the most challenging. Current evidence suggests that both volume overload and aggressive fluid removal can induce circulatory stress and multi-organ injury. Furthermore, we do not have accurate volume assessment tools. As a result, targeting euvolemia might result in more harm than benefit with conventional hemodialysis therapy. Therefore, it might be time to consider a degree of permissive over-hydration until we have better tools to both determine ideal weight and improve current renal replacement therapy so that the process of achieving it is not so fraught with the current dangers. © 2014 Wiley Periodicals, Inc.

    This study examined the clinical significance of N-terminal pro brain natriuretic peptide level as a cardiac marker in Japanese hemodialysis patients. This was a multicenter cross-sectional study involving 1428 Japanese hemodialysis patients. Ultrasonic cardiography data at post-hemodialysis were obtained from 395 patients. We examined whether serum N-terminal pro brain natriuretic peptide levels were associated with cardiac parameters and assessed cut-off values and investigated factors associated with a reduced ratio of N-terminal pro brain natriuretic peptide levels pre- and post-hemodialysis. Multivariate logistic regression analysis showed that pre- and post-hemodialysis N-terminal pro brain natriuretic peptide levels were associated with left ventricular hypertrophy on electrocardiogram (odds ratio: 3.10; p N-terminal pro brain natriuretic peptide levels were also significantly associated with ejection fraction on urine chorionic gonadotrophin (ultrasonic cardiography; odds ratio: 35.83; p N-terminal pro brain natriuretic peptide reduction ratio during a hemodialysis session correlated with Kt/V, membrane area, membrane type, modality, body weight gain ratio, treatment time, and ultrafiltration rate with multiple linear regression ( R: 0.53; p N-terminal pro brain natriuretic peptide are associated with the presence of left ventricular hypertrophy in this population. The post-hemodialysis N-terminal pro brain natriuretic peptide level is a useful marker for systolic dysfunction.

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

    Full Text Available 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.

    Malnutrition is multifactorial and may be modified by nutritional intervention. We aimed to assess the impact of an intervention on the nutritional status of malnourished hemodialysis patients and their acceptance of a non-industrialized nutritional supplement. 18 patients were studied, they were selected from a previous nutritional assessment where nutritional risk was defined as: subjective global assessment > 15 plus one criterion for malnutrition. The following variables were assessed: anthropometric parameters, subjective global assessment, dietary intake, six-minute walking test, quality of life (SF-36), and biochemical tests. Patients were randomized to either Control or Intervention Groups. The Intervention Group received a dietetic supplement during dialysis containing 355 kcal, prepared from simple ingredients. After three months, subjects from the Control Group and other patients also considered at nutritional risk underwent the same intervention. The study groups were compared after three months, and all patients were analyzed before and after the intervention. Fifteen men and three women, aged 56.4 ± 15.6 years-old, nine in each group, were studied. The Intervention Group showed an improvement in the subjective global assessment (p = 0.04). There were differences in role physical and bodily pain domains of SF-36, with improvement in the Intervention Group and worsening in the Control Group (p = 0.034 and p = 0.021). Comparisons before and after intervention for all patients showed improvement in the subjective global assessment (16.18 ± 4.27 versus 14.37 ± 4.20, p = 0.04), and in the six-minute walking test (496.60 ± 132.59 versus 547.80 ± 132.48 m; p = 0.036). The nutritional supplement was well tolerated by all patients, and it did not cause side effects. The nutritional intervention improved the subjective global assessment and quality of life of hemodialysis patients at short-term. A global intervention by a dietitian produced specific and

    Background: Restless leg syndrome prevalence is high among the patients undergoing hemodialysis. Due to several side effects of medicational treatments, the patients prefer non-medicational methods. Therefore, the present study aimed to investigate the effects of two methods of reflexology and stretching exercises on the severity of restless leg syndrome among patients undergoing hemodialysis. Materials and Methods: This study is a randomized clinical trial that was done on 90 qualified patients undergoing hemodialysis in selected hospitals of Isfahan, who were diagnosed with restless leg syndrome through standard restless leg syndrome questionnaire. They were randomly assigned by random number table to three groups: Reflexology, stretching exercises, and control groups through random allocation. Foot reflexology and stretching exercises were conducted three times a week for 30–40 min within straight 4 weeks. Data analysis was performed by SPSS version 18 using descriptive and inferential statistical analyses [one-way analysis of variance (ANOVA), paired t-test, and least significant difference (LSD) post hoc test]. Results: There was a significant difference in the mean scores of restless leg syndrome severity between reflexology and stretching exercises groups, compared to control (P restless leg syndrome severity were significantly higher in reflexology and stretching exercises groups compared to the control group (P restless leg syndrome. These two methods of treatment are recommended to the patients. PMID:27186197

    The association between serum uric acid (SUA) and mortality has been conflicting among studies using hemodialysis (HD) patients. Given the close link between purine and protein in foods, we hypothesized that normalized protein catabolic rate (nPCR), a dietary protein intake surrogate, modifies the SUA-mortality association in the HD population. We identified 4298 patients who initiated HD and had one or more SUA measurement in a contemporary cohort of HD patients over 5 years (1 January 2007-31 December 2011), and examined survival probability according to the first uric acid measurement, adjusting for dialysis vintage, case-mix and malnutrition-inflammation complex-related variables. Mean SUA concentration was 6.6 ± 1.8 mg/dL. There was a consistent association of higher SUA with better nutritional status and lower all-cause mortality irrespective of adjusted models (Ptrend 6.0-7.0 mg/dL) showed no significant mortality risk [hazard ratio (HR) 0.90, 95% confidence interval (CI) 0.72-1.13], while the lowest category (patients with low nPCR (nutritional marker in HD patients. Contrary to the general population, low but not high SUA is associated with higher all-cause mortality in HD patients, especially in those with low protein intake. Nutritional features of SUA warrant additional studies. © The Author 2017. Published by Oxford University Press on behalf of ERA-EDTA. All rights reserved.

    Hemodialysis vascular access dysfunction, mostly attributed to neointimal hyperplasia, is a major cause of morbidity and hospitalization in patients on hemodialysis. It has been reported that prostaglandin I 2 has pleiotropic effects including anti-platelet, vasodilating, anti-inflammatory, and anti-atherogenic properties. In addition, several studies have shown that prostaglandin I 2 can inhibit neointimal formation after vascular injury. This study aimed to investigate the effects of beraprost sodium, an oral synthetic analog of prostaglandin I 2 , on vascular access patency in patients on hemodialysis who experienced primary hemodialysis vascular access failure. Fifty-five patients with end-stage renal disease who were on hemodialysis were prospectively selected for this study. Twenty-three patients were assigned to be treated with 120 µg/day of beraprost sodium, while remaining patients (n = 32) were assigned to a control group. The primary outcome was primary unassisted vascular access patency at 2 years. The incidence of primary unassisted patency at 2 years was 83% in the beraprost sodium group and 38% in the control group (p = 0.001). Analysis of covariables indicated that this effect occurred mainly as a result of beraprost sodium administration. No life-threatening adverse event or severe bleeding was recorded in any of the groups. Our data indicated that an oral prostaglandin I 2 analog, beraprost sodium, is effective and safe for the maintenance of vascular access patency in patients on hemodialysis with primary vascular access failure.

    A retrospective study was performed in 41 patients, in chronic hemodialysis with severe hyperparathyroidism (HPT), who underwent surgery during time period from 1985 to 1997. 22 females, 19 males, aged 50 and 14 years, with PTHI 1345 and 604 pg/ml were followed up 32 and 22 months. Three surgical methods we evaluated: group I) total para thyroidectomy(PTX) with Implants(n=24); group II) subtotal PTX(n=14) and group III) total PTX(n=3). It considered recurrence of HPT when PTH levels were higher than upper range of normal, after 6 months post surgery. persistence was defined when there was no standardization of PTH levels. In group I, 9 patients had normal parathyroid function, 7 had persistent hypoparathyroidism and had hyperparathyroidism (7 recurrences). Group II patients had parathyroid over function in 5 cases (4 persistence s), 5 were normal and 4 hypoparathyroidism. All patients of the third group had hypoparathyroidism. Long term normalization of parathyroid gland activity was achieved in one third of troduccion patients (34,1%) whereas 34,1% permanent hypoparathyroidism and 31,8% hyperparathyroidism. It found no differences in recurrence and histological subtype of parathyroid gland in the different groups. In conclusion, similar long term clinical results were obtained with the different groups. The surgical ideal treatment is controversial. We think that in the long run, the evolution of parathyroid status is mostly influenced by the persistence of uremic state rather than the type of surgery performed [es

    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 (paggression which destroys their social communications. Some response measures for depression such as relaxation training, psychological support, music therapy, or peripheral biofeedback are recommended.

    Full Text Available INTRODUCTION: Uremic pruritus is common among dialysis patients. Effective treatments are not readily available. Early evidence with antihistamines and gabapentin indicate variable effects. OBJECTIVE: To compare the efficacy and side effects of gabapentin and desloratadine in patients with dialysis pruritus. METHODS: Prospective, open-label, cross-over clinical trial in 22 patients on chronic hemodialysis with sustained pruritus over a period of at least 60 days. After a one-week run-in period, we assigned patients to three weeks of either gabapentin 300 mg thrice weekly or desloratadine 5 mg thrice weekly. After a one-week washout period, each patient crossed-over to the alternate regimen for three more weeks. The primary endpoint of the study was the change in the visual analogue pruritus score (VAS. RESULTS: Nineteen subjects completed the two treatment blocks and were available for analysis. VAS scores decreased with both treatments (5.95 to 4.6 with gabapentin, p = 0.07; 5.89 to 3.4 with desloratadine, p = 0.004, but only desloratadine reached statistical significance. There were no differences when comparing the final pruritus score with gabapentin and desloratadine (4.6 versus 3.4, p = 0.16 Excessive sedation was common with gabapentin. Desloratadine was well tolerated. CONCLUSION: Desloratadine provides significant relief of uremic pruritus compared with no therapy. gabapentin has marginal efficacy. Desloratadine is better tolerated than gabapentin.

    Pulse wave velocity (PWV) is a predictor of morbidity and mortality in patients with end-stage renal disease (ESRD). Dialysis patients show cyclic changes in PWV related to their hydration status and blood pressure. Our aim is to assess the impact of daily dialysis on PWV. We performed a randomized crossover study of 60 patients who underwent standard hemodialysis (HD) three times per week for at least 6 months. Patients were classified into three groups according to their PWV values before (pre-) and after (post-) HD, with a cutoff value of 12 m s(-1), as follows: the low-low (LL) group had normal pre-HD and post-HD PWV; the high-low (HL) group had high pre-HD PWV and normal post-HD PWV; and the high-high (HH) group had high pre- and post-HD PWV. All patients continued standard HD for 2 weeks. A total of 10 patients from each group were randomly assigned to continue standard HD for 1 week and then underwent daily dialysis for 1 week. The remaining 10 patients underwent daily dialysis for 1 week and then underwent standard HD for 1 week. PWV values were measured before and 1 h after each dialysis session. With daily dialysis treatment, 2 of 20 patients (10%) moved from the PWV-HH group to the PWV-HL group, whereas 18 of 20 patients (90%) moved from the PWV-HL group to the PWV-LL group (P = 0.030). Daily dialysis reduces PWV in the ESRD patients. As PWV is a strong predictor of mortality in ESRD and has cyclic variations in patients who are on standard HD, we believe that daily dialysis may be used in patients with high PWV levels to reduce their mortality risk.

    Hemodialysis (HD) and peritoneal dialysis (PD) are important renal replacement treatments in end stage renal disease (ESRD). There is paucity of data comparing outcomes and quality of life (QOL) between the two modalities in Indian scenario. We followed 60 End stage renal disease patients (30 CAPD and 30 Maintenance hemodialysis) for a period of one year. Patients were analysed and compared for complications, physical quality of life and psychological well being with a two part self reported questionnaire at baseline and subsequently at six and twelve months. For the physical component appropriate sections of the McMaster Health Index Questionnaire (MHIQ) and for psychological component Psychological General Well-Being Index (PGWB) developed by Dupey was applied. The number of males and females in both groups were comparable (p-value > 0.05).The prevalence of diabetes mellitus, coronary artery disease, obesity and ischaemic heart disease was comparable in both groups (p-value>0.05). Significantly higher mortality was observed in patients undergoing HD (20% vs 0 %, p-value psychological aspects and have significantly lower mortality when compared with hemodialysis patients.

The aim of this study was to assess HRQoL in patients on chronic maintenance hemodialysis (HD, and compare it with patients suffering from hypertension (HTA, and normal controls of the same age and gender (C. Methods. The study enrolled 224 males and females older than 18 years: 67 in the HD group, 78 in the HTA group, and 79 in the C group. HRQoL was assessed in all groups using 15-D questionnaire. Results. Significantly higher level of education was recorded in the HD group compared to other two groups. In the HD group there were significantly less employed persons (9% and significantly more retired (67.2%. All groups were similar regarding an average monthly income and marital status. We found significantly lower total HRQoL score in patients in the HD group, compared to normal controls (0.78 ± 0.16 vs. 0.89 ± 0.10 in the HTA and 0.95 ± 0.06 in the C group as well as specific scores in almost all investigated domains, except in speech, eating and mental functions. Patients in the HD and HTA groups had similar self-reported quality of life in additional 3 domains: hearing, elimination and distress, while the HD group reported significantly lower scores in remaining 9 domains: mobility, vision, breathing, sleeping, usual activities, discomfort and symptoms, depression, vitality and sexual activity. Patients in the HTA group had significantly lower scores than normal controls in 8 domains (hearing, sleeping, elimination, usual activities, discomfort and symptoms, depression, distress and vitality as well as in total quality of life, while in remaining 4 domains there was no significant difference (mobility, vision, breathing, sexual activity.

    Summary Background and objectives End-stage renal disease is linked to alterations in thyroid hormone levels and/or metabolism, resulting in a high prevalence of subclinical hypothyroidism and low triiodothyronine (T3) levels. These alterations are involved in endothelial damage, cardiac abnormalities, and inflammation, but the exact mechanisms are unclear. In this study, we investigated the relationship between serum free-T3 (fT3) and carotid artery atherosclerosis, arterial stiffness, and vascular calcification in prevalent patients on conventional hemodialysis. Design, setting, participants, & measurements 137 patients were included. Thyroid-hormone levels were determined by chemiluminescent immunoassay, carotid artery–intima media thickness (CA-IMT) by Doppler ultrasonography, carotid-femoral pulse wave velocity (c-f PWV), and augmentation index by Sphygmocor device, and coronary artery calcification (CAC) scores by multi-slice computerized tomography. Results Mean fT3 level was 3.70 ± 1.23 pmol/L. Across decreasing fT3 tertiles, c-f PWV and CA-IMT values were incrementally higher, whereas CACs were not different. In adjusted ordinal logistic regression analysis, fT3 level (odds ratio, 0.81; 95% confidence interval, 0.68 to 0.97), age, and interdialytic weight gain were significantly associated with CA-IMT. fT3 level was associated with c-f PWV in nondiabetics but not in diabetics. In nondiabetics (n = 113), c-f PWV was positively associated with age and systolic BP but negatively with fT3 levels (odds ratio = 0.57, 95% confidence interval 0.39 to 0.83). Conclusions fT3 levels are inversely associated with carotid atherosclerosis but not with CAC in hemodialysis patients. Also, fT3 levels are inversely associated with surrogates of arterial stiffness in nondiabetics. PMID:21836150

    To evaluate how different compartments of body composition can affect survival in hemodialysis (HD) patients. Multicenter longitudinal observational study of a cohort of patients in HD with 12 months of follow-up. Patients from 34 Nephrocare dialysis units in Portugal were included. A total of 697 patients on maintenance HD during 4 hours 3 days per week were enrolled. Dry weight, presence of diabetes, body mass index (BMI), lean tissue index (LTI), fat tissue index (FTI), body cell mass index (BCMI), albumin and hydration status were recorded at baseline. In all patients, the assessment of body composition was carried out using the Body Composition Monitor (BCM; Fresenius Medical Care a Deutschland GmbH, Germany). Survival during a 12-month period of follow-up. Patient's mean (±standard deviation) age was 65.4 ± 14.3 years, and median (interquartile range) HD vintage was 41 (19-81) months. Patients who died during the study period, had higher age (P < .001), lower dry weight (P = .001), BMI (P < .001), albumin (P < .001), LTI (P = .015), and also lower BCMI (P = .046). Patients with diabetes (P = .045), BMI < 18.5 kg/m(2) (P < .001), albumin < 4.0 g/dL (P < .001), relative overhydration ≥ 15% (P = .001), low FTI (P = .019), and also those in the lowest tertile of BCMI (P = .022) displayed a significantly worse survival. In the Cox regression analysis, the overall mortality of patient was related to low FTI, relative overhydration, BMI < 18.5 kg/m(2), BCMI ≤ 5.2 kg/m(2), and albumin < 4.0 g/dL. Several body composition parameters demonstrated to have an important role in predicting 1-year mortality in HD patients. Albumin, FTI, and BMI were useful predictors of mortality in these patients.

    Hemolytic uremic syndrome (HUS) is characterized by hemolytic anemia, low platelets, and renal impairment and is mediated by thrombotic microangiopathy (TMA). A common perception is that HUS becomes dormant in dialysis patients with end-stage renal disease (ESRD). We analyzed patients in a large dialysis organization to understand the potential consequences and burden of HUS. We identified patients with ESRD ascribed to HUS and those with ESRD ascribed to another cause (control patients) who received hemodialysis or peritoneal dialysis from 01 January 2007 to 31 December 2012. Outcomes were survival, hospitalization, and longitudinal laboratory values associated with TMA, including lactate dehydrogenase, red cell distribution width (RDW), platelets, and hemoglobin. HUS patients (n = 217) were propensity-score matched 1:5 to control patients (n = 1,085) for age, gender, race, dry weight, insurance, access, comorbidities, and Charlson comorbidity index. Compared to control patients, HUS patients had significantly greater risk for hospitalizations overall (RR = 2.3, p = 0.004) and hospitalization for hematologic (RR = 5.6, p = 0.001), cardiovascular (RR = 2.1, p = 0.02), and pancreatic (RR = 7.9, p = 0.04) causes. HUS patients also had evidence of ongoing TMA: higher lactate dehydrogenase and RDW, lower platelets and hemoglobin, and more frequent lactate dehydrogenase spikes. Dialysis patients with HUS were at significantly higher risk than matched control patients for hospitalizations due to cardiovascular, hematologic, and pancreatic disease, which were associated with ongoing TMA. Additional studies are needed to determine whether targeted therapy for HUS reduces hospitalizations.

    We report a female with amyloid arthropathy of the hip joints. She was a 67-year-old woman who had been treated by hemodialysis for 22 years. She had demonstrated a 5-month history of continuous low-grade fever and pain in her left hip and she was finally unable to walk by herself. Findings on X-ray films and MRI of the hip joints suggested avascular necrosis in both femur heads. To palliate symptoms, bipolar surgery on the left hip joint was performed. Pathological examination of bone tissue specimen demonstrated that there was some , β 2 -microglobulin (β 2 -MG)-related amyloid accumulation in the femur head. Based on this clinical experience, we performed MRI screening for amyloid lesions of the hip joints in another 11 asymptomatic female patients undergoing hemodialysis for 20 years or more. Cystic lesions of the hip joints were observed in 8 patients, amyloid arthropathy in 2 patients, and fluid trapped in the joint in 1 patient. Patients with amyloidosis had significantly lower serum β 2 -MG levels than patients without amyloidosis (28.6 mg/L versus 41.4 mg/L; p=0.0339). Our findings show that dialysis-related amyloidosis of the hip joints is one of the potential and significant problems in female patients on long-term hemodialysis therapy. It may be important to screen for this pathological condition in long-term hemodialysis patients. (author)

    Full Text Available Pentraxin 3 (PTX3, a multifunctional modulator of the innate immunoinflammatory response, is higher in patients undergoing hemodialysis than healthy control. Our study focused on annual change in PTX3 levels in patients with chronic hemodialysis, because regularly undergoing hemodialysis for many years modifies vascular inflammatory status. To demonstrate whether annual change in PTX3 is associated with vascular events, we measured blood levels of pentraxins (PTX3 and high-sensitivity C-reactive protein (hsCRP at baseline and in the next year in 76 hemodialysis patients and observed 20 patients with vascular access troubles during follow-up years. The annual decline in PTX3, but not hsCRP, is a significant risk of the incidence of vascular access trouble that is a critical and specific complication for hemodialysis patients (hazard ratio; 0.732 per +1 ng/mL/year in PTX3, *P=0.039. This study is the first to focus on the annual change of pentraxins in a hemodialysis cohort.

    Full Text Available Introduction: One of the main complications of hemodialysis in patients with chronic renal failure is hypoxemia which is related to several factors including the type of filter. The aim of this study was to evaluate the hypoxemia levels in patients undergoing hemodialysis with focus on the type of filter. Methods: In a crossover clinical trial, 29 patients from emodialysis ward of Fatemieh hospital were enrolled in the study. The patients were randomly divided in two groups (allocation. First group was hemodialyzed using Polysulfone filters while the second group was hemodialyzed by Hemoph an filters for one month. After a period of 24 hours washout, filter was changed and hemodialysis was done for another month. Arterial blood O2 saturation at different times, before and after hemodialysis was determined and amount of decrement was measured and compared in both groups. Results: Mean decrease in the arterial blood O2 saturation during 5, 30, 60 and 120 minutes after initiation of hemodialysis was higher in Hemophan filter than Polysulfone filter (p<0.001. In both groups, peak of decreasing levels were 30 and 60 minutes after initiation of hemodialysis. Conclusion: As use of polysulfone filters causes lesser decrease in arterial blood oxygen saturation, it is recommended in igh risk, especially cardiopulmonary disease patients

    Full Text Available Background/Aim. Cardiovascular diseases are the leading cause of death in patients treated with hemodialysis (HD. The annual cardiovascular mortality rate in these patients is 9%. Left ventricular (LV hypertrophy, ischemic heart disease and heart failure are the most prevalent cardiovascular causes of death. The aim of this study was to assess the prevalence of traditional and nontraditional risk factors for cardiovascular complications, to assess the prevalence of cardiovascular complications and overall and cardiovascular mortality rate in patients on HD. Methods. We investigated a total of 115 patients undergoing HD for at least 6 months. First, a cross-sectional study was performed, followed by a two-year follow-up study. Beside standard biochemical parameters, we also determined cardiac troponins and echocardiographic parameters of LV morphology and function (LV mass index, LV fractional shortening, LV ejection fraction. The results were analyzed using the Student's t test and Mann-Whitney U test. Results. The patients with adverse outcome had significantly lower serum albumin (p < 0.01 and higher serum homocystein, troponin I and T, and LV mass index (p < 0.01. Hyperhomocysteinemia, anemia, hypertriglyceridemia and uncontrolled hypertension had the highest prevalence (86.09%, 76.52%, 43.48% and 36.52%, respectively among all investigated cardiovascular risk factors. Hypertrophy of the LV was presented in 71.31% of the patients and congestive heart failure in 8.70%. Heart valve calcification was found in 48.70% of the patients, pericardial effusion in 25.22% and disrrhythmia in 20.87% of the investigated patients. The average annual overall mortality rate was 13.74%, while average cardiovascular mortality rate was 8.51%. Conclusion. Patients on HD have high risk for cardiovascular morbidity and mortality.

    Full Text Available Cardiovascular diseases are a major cause of morbidity and mortality in patients with end-stage renal disease (ESRD. The aim of our investigation was the evaluation of an extensive cardiovascular profile in hemodialysis (HD and peritoneal dialysis (PD patients. We studied 74 patients with ESRD (38 males, 36 females, maintained either on chronic HD (n= 50 or chronic PD (n= 24 and age and sex matched 20 healthy subjects as controls. The lipid profile, homo-cysteine (Hcy and C reactive protein (CRP were measured. When compared to a healthy popu-lation, HD patients displayed a marked atherogenic profile, as attested by increased levels of total cholesterol (TC, triglycerides (TG, low-density lipoprotein-cholesterol (LDL-C, apolipoprotein A (Apo A, CRP, Hcy and lower concentrations of high-density lipoprotein-cholesterol (HDL-C, Apo B, albumin (ALB. A significant difference was noted concerning the rates of Apo B, HDL-C, TC, ALB and Hcy. Same biological disorders that those found at HD patients were noted in these PD patients. One also noted lower concentration in Apo A. there were a significant diffe-rence with the reference group concerning the rates of albumin, Apo A, HDL-Cl and Hcy. When compared to PD patients, HD patients had significantly decreased concentration of LDL-C. The peculiar metabolic changes observed in the present study confirm the marked tendency of patients with impaired renal function for developing cardiovascular diseases, irrespectively of the type of dialysis. We suggest including uremia-related risk factors in the panel for evaluation of cardio-vascular risk in dialysis patients.

    This review examined the impact of Therapeutic Patient Education (TPE) programs in hemodialysis and the assessment of these programs. REVIEW METHODS AND DATA SOURCES: A systematic review was performed. Bibliographical research was done with a database in the social and human sciences (PsychINFO, PsycARTICLES, SocINDEX with Full Text and the Psychology and Behavioural Sciences Collection). References were also searched in several reviews specialized in nephrology-dialysis and in patient education. Articles were classified according three different outcomes: (1) physiological outcomes, (2) psychosocial outcomes, (3) or combined criteria. 35 articles were selected. The majority dealt with purely physiological outcomes (18) and the minority concerned only psychosocial outcomes (4). Fifteen articles discussed both physiological and psychosocial outcomes, i.e. combined criteria. Beneficial effects were shown such as improvements in knowledge, adherence and quality of life. Most educational interventions were performed by nurses. This systematic review found that educational programs in dialysis have become more numerous and efficient, with a prevalence of assessment based on physiological outcomes. TPE is a global management method based on both the physiological and the psychological well-being of the patient. Studies that take into account both physiological and psychosocial variables are very useful for understanding the effects of TPE programs on dialysis patients. The review shows that nurses play an important role in TPE and that they require varied communicational, educational, animation and assessment skills. These positive effects are encouraging for nurses to stimulate the development of TPE programs for dialysis patients in their multidisciplinary teams. The nurse's role is important for the commitment of each health caregiver (nurse, physician, dietician, pharmacist, psychologist, etc.) for the global management of patients in the TPE process. 2011 Elsevier

    Full Text Available ABSTRACT OBJECTIVE To examine whether the level of complexity of the services structure and sociodemographic and clinical characteristics of patients in hemodialysis are associated with the prevalence of poor health self-assessment. METHODS In this cross-sectional study, we evaluated 1,621 patients with chronic terminal kidney disease on hemodialysis accompanied in 81 dialysis services in the Brazilian Unified Health System in 2007. Sampling was performed by conglomerate in two stages and a structured questionnaire was applied to participants. Multilevel multiple logistic regression was used for data analysis. RESULTS The prevalence of poor health self-assessment was of 54.5%, and in multivariable analysis it was associated with the following variables: increasing age (OR = 1.02; 95%CI 1.01–1.02, separated or divorced marital status (OR = 0.62; 95%CI 0.34–0.88, having 12 years or more of study (OR = 0.51; 95%CI 0.37–0.71, spending more than 60 minutes in commuting between home and the dialysis service (OR = 1.80; 95%CI 1.29–2.51, having three or more self-referred diseases (OR = 2.20; 95%CI 1.33–3.62, and reporting some (OR = 2.17; 95%CI 1.66–2.84 or a lot of (OR = 2.74; 95%CI 2.04–3.68 trouble falling asleep. Individuals in treatment in dialysis services with the highest level of complexity in the structure presented less chance of performing a self-assessment of their health as bad (OR = 0.59; 95%CI 0.42–0.84. CONCLUSIONS We showed poor health self-assessment is associated with age, years of formal education, marital status, home commuting time to the dialysis service, number of self-referred diseases, report of trouble sleeping, and also with the level of complexity of the structure of health services. Acknowledging these factors can contribute to the development of strategies to improve the health of patients in hemodialysis in the Brazilian Unified Health System.

    Full Text Available 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.

    High- and low-flux hemodialysis (HFHD and LFHD, respectively) are dialysis procedures designed to eliminate blood toxins that accumulate in end-stage renal disease. HFHD may reduce vascular calcification by removing serum fibroblast growth factor 23 (FGF-23). However, whether HFHD is better than LFHD is still under debate. We therefore compared the efficacy of HFHD and LFHD in controlling FGF-23 and vascular calcification. Fifty hemodialysis patients were recruited and randomly treated with either HFHD or LFHD. Fasting venous blood was collected at baseline, six months, and twelve months after the treatment. We then measured levels of FGF-23, calcium, phosphorus, parathyroid hormone, and alkaline phosphatase. Further, abdominal lateral radiographs were taken to calculate aorta abdominalis calcification scores (AACs). Compared to the LFHD group, FGF-23 and AACs in the HFHD group significantly decreased after 12 months treatment (p=0.049 and p=0.002, respectively). AACs were positively correlated with FGF-23 in all patients (p=0.004), the HFHD group alone (p=0.040), and the LFHD group alone (p=0.037). We also found that older patients, patients with higher blood phosphorus levels, and higher FGF-23 levels had an increased risk of aorta abdominalis calcification (p=0.048, p=0.003, p=0.001, respectively). HFHD was more able to reduce the risk of aorta abdominalis calcification than LFHD (p=0.003). FGF-23 is an independent risk factor for the development of vascular calcification. HFHD may benefit hemodialysis patients by reducing serum FGF-23 levels and controlling vascular calcification.

    BACKGROUND: There is a paucity of data concerning the risks associated with warfarin in hemodialysis (HD) patients. We compared major bleeding episodes in this group with HD patients not receiving warfarin and with a cohort of non-HD patients receiving warfarin. METHODS: A retrospective review of 141 HD patients on warfarin (HDW), 704 HD patients not on warfarin (HDNW) and 3,266 non-dialysis warfarin patients (NDW) was performed. Hospital admissions for hemorrhagic events and ischemic strokes were examined as was hospital length of stay and blood product use. INR variability was also assessed. RESULTS: The incidence rates for major hemorrhage per 100 patient years was 10.8 in the HDW group as compared to 8.0 in the HDNW (p = 0.593) and 2.1 in the NDW (p < 0.001) groups. Mean units of red blood cell transfusions required was higher in patients on dialysis with no significant difference between HDW and HDNW groups. The risk of ischemic stroke per 100 patient years was 1.7 in the HDW group as compared to 0.7 in the HDNW groups (p = 0.636) and 0.4 in the NDW (p = 0.003). The HDW group had higher inter-measurement INR variability compared to the NDW group (p = 0.034). In patients with atrial fibrillation, HDW group had a higher incidence of ischemic stroke than the NDW group (2.2 versus 0.4 events per 100 patient years; p = 0.024). CONCLUSIONS: This study confirms the higher bleeding risk associated with HD\\/ESRD but suggests that warfarin use in these patients may not add significantly to this risk. We also demonstrated high rates of ischemic stroke in HD patients despite warfarin use. SUMMARY: Our study compares the frequency of major hemorrhage and secondarily, ischemic stroke in HD patients receiving or not receiving warfarin, with non-HD patients receiving warfarin. The major finding was that frequency of hemorrhage was higher in HD patients receiving warfarin than in non-HD patients receiving warfarin, but not different in HD patients with or without warfarin.

The HDW group had higher inter-measurement INR variability compared to the NDW group (p = 0.034). In patients with atrial fibrillation, HDW group had a higher incidence of ischemic stroke than the NDW group (2.2 versus 0.4 events per 100 patient years; p = 0.024). Conclusions: This study confirms the higher bleeding risk associated with HD\\/ESRD but suggests that warfarin use in these patients may not add significantly to this risk. We also demonstrated high rates of ischemic stroke in HD patients despite warfarin use. Summary: Our study compares the frequency of major hemorrhage and secondarily, ischemic stroke in HD patients receiving or not receiving warfarin, with non-HD patients receiving warfarin. The major finding was that frequency of hemorrhage was higher in HD patients receiving warfarin than in non-HD patients receiving warfarin, but not different in HD patients with or without warfarin.

    Background Patients undergoing hemodialysis are at high risk of falls, with subsequent complications including fractures, loss of independence, hospitalization, and institutionalization. Factors associated with falls are poorly understood in this population. We hypothesized that insights derived from studies of the elderly might apply to adults of all ages undergoing hemodialysis; we focused on frailty, a phenotype of physiological decline strongly associated with falls in the elderly.

    This study determined the effects of probiotic supplementation on glycemic control, lipid concentrations, biomarkers of inflammation and oxidative stress in 60 diabetic patients on hemodialysis in a parallel randomized double-blind placebo-controlled clinical trial. Participants were initially matched based on sex, duration of dialysis and diabetes, body mass index and age. Subsequently, they were randomly divided into two groups to take either a capsule containing the probiotics Lactobacillus acidophilus, Lactobacillus casei and Bifidobacterium bifidum or placebo for 12 weeks. Based on three-day dietary records throughout the trial, there was no significant change in dietary macro- and micro-nutrients or total dietary fiber to confound results. After the 12 weeks, analysis of patients who received probiotic supplements compared with the placebo showed they had significantly decreased fasting plasma glucose (-22.0 vs. +6.6 mg/dl), serum insulin (-6.4 vs. +2.3 μIU/ml), homeostasis model of assessment-estimated insulin resistance (-2.9 vs. +2.5), homeostasis model of assessment-estimated beta-cell function (-14.1 vs. +6.1) and HbA1c (-0.4 vs. -0.1%,), and improved quantitative insulin sensitivity check index (+0.03 vs. -0.02). Additionally, compared with the placebo, probiotic supplementation resulted in significant reductions in serum high-sensitivity C-reactive protein (-1933 vs. +252 ng/ml), plasma malondialdehyde (-0.3 vs. +1.0 μmol/l), subjective global assessment scores (-0.7 vs. +0.7) and total iron binding capacity (-230 vs. +33 μg/dl), and a significant increase in plasma total antioxidant capacity (+15 vs. -88 mmol/l). Thus, probiotic supplementation for 12 weeks among diabetic hemodialysis patients had beneficial effects on parameters of glucose homeostasis, and some biomarkers of inflammation and oxidative stress.

    Full text: Treatment with radioactive iodine ( 131 I) may be necessary for toxic adenoma of the thyroid in patients with end-stage renal disease (ESRD) who require hemodialysis (HD). Because 131 I is cleared mainly by the kidneys in patients with normal renal function, many issues arise as in patients who require 131 I treatment but who are on hemodialysis, as radiation safety considerations, contamination of equipment, lines and filter and disposal of wastes. This paper presents a case report of a patient on dialysis that required treatment with 131 I. Methodology: 87 years old man with ESRD in HD (4hrs/3 times a week) during 8 years. He had hyperthyroidism secondary to a toxic adenoma. 30 mCi of 131 I is indicated. During dialysis an individual filter is used. The dialysis room (40 m 2 ) is shared with other 5 patients. The dialysed liquid is discharged. 'In vitro' study previous to the 131 I administration was carried on in order to analyzed the eventual contamination of the dialysis machine, using the same kind of filter, with a blood circuit (Qb 250 ml/min) and dialysate solution (Qd 500 ml/min). 10 uCi/ 5 ml of water was administered at the blood entrance and 8 samples were taken (blood output and input and output of dialysate solution), between 1 and 20 min post injection. syringes, lines and filter where taken to the Nuclear Medicine Unit for counting and disposal. Immediately after dialysis 30 mCi of 131 I where administered. The patient was admitted in the hospital. The exposition dose from the patient (mR/h) at one meter during the next 4 days was measured. The next HD (new filter) was done 88 hrs after the radioiodine treatment. The dose from the patient and the dialysis machine was determinate as well as the dose received by the nurse and the other patients. After dialysis, lines and the filter were counted. The patient was discharged from the hospital 5 days after therapy. Results: In Vitro-Pre treatment study: Background: 20 uR/h; 'venous' output: 43

    Full Text Available Patients with chronic renal insufficiency (CRI have reduced hemoglobin levels, mostly as a result of decreased kidney production of erythropoietin, but the relation between renal insufficiency and the magnitude of hemoglobin reduction has not been well defined. Hereditary hemochromatosis is an inherited disorder of iron metabolism. The importance of the association of hemochromatosis with treatment for anemia among patients with CRI has not been well described. We analyzed the frequency of the C282Y and H63D mutations in the HFE gene in 201 Brazilian individuals with CRI undergoing hemodialysis. The analysis of the effects of HFE mutations on iron metabolism and anemia with biochemical parameters was possible in 118 patients of this study (hemoglobin, hematocrit, ferritin levels, transferrin saturation, and serum iron. A C282Y heterozygous mutation was found in 7/201 (3.4% and H63D homozygous and heterozygous mutation were found in 2/201 (1.0% and 46/201 (22.9%, respectively. The allelic frequencies of the HFE mutations (0.017 for C282Y mutation and 0.124 for H63D mutation did not differ between patients with CRI and healthy controls. Regarding the biochemical parameters, no differences were observed between HFE heterozygous and mutation-negative patients, although ferritin levels were not higher among patients with the H63D mutation (P = 0.08. From what we observed in our study, C282Y/H63D HFE gene mutations are not related to degrees of anemia or iron stores in CRI patients receiving intravenous iron supplementation (P > 0.10. Nevertheless, the present data suggest that the H63D mutation may have an important function as a modulating factor of iron overload in these patients.

    Full Text Available Branka Sladoje-Martinovic, Ivana Mikolasevic, Ivan Bubic, Sanjin Racki, Lidija OrlicDepartment of Nephrology and Dialysis, Division of Internal Medicine, University Hospital Center Rijeka, Rijeka, CroatiaBackground/aim: The number of elderly patients with chronic kidney disease (CKD stage 5 management with hemodialysis (HD is steadily increasing. Therefore we analyzed the number of new CKD patients ≥80 years managed with HD and their survival through the study period. We aimed also, to identify which of several key variables might be independently associated with survival in this very elderly population of patients.Patients and methods: This was a single-center, retrospective cohort study that took place during the period from January 1987 to September 2012. The study consisted of 78 (50 male and 28 women very elderly patients (≥80 years of age; the mean age at which HD was initiated was 83.2±2.5 years. Survival and factors associated with mortality were studied. Survival was defined as the time from start of HD treatment to death (or end of study, if still alive.Results: In the period from 1987 to 2002, patients ≥80 years of age were only sporadically treated with HD, but since 2003, the number of new patients has been steadily increasing. The mean survival for our group of patients was 25.1±22.4 months (range 1–115 months. Furthermore, 30.8% patients survived <12 months, 29.5% patients survived 12–24 months, 30.8% patients survived 24–60 months, and 9% patients survived >60 months on HD treatment. Older patients were less likely to have diabetes, and primary renal disease did not influence survival. Patients with high C-reactive protein levels and poor nutritional status, as well as those who did not have pre-HD nephrology care and those that had a catheter as vascular access for HD had poor survival. In about half of our patients, the cause of death was cardiovascular disease.Conclusion: Among patients who were ≥80 years of

    To study the frequency of restless legs syndrome in patients of end stage renal disease undergoing maintenance hemodialysis. Design: Cross sectional descriptive study. Place and Duration of Study: Department of medicine, CMH Multan from Nov 2010 to April 2011. Patients and Methods: One hundred and ninety four (n=194) patients of End stage renal disease who had been on maintenance hemodialysis for at least 3 months, were included in the study after full informed consent and using consecutive sampling. Patients having dementia, psychiatric illness, pregnancy, hypothyroidism, Parkinson's disease and alcoholics were excluded from the study. Patients who fulfilled all four diagnostic criteria for restless legs syndrome as proposed by International restless legs syndrome study group (IRLSSG), by direct questioning were diagnosed as having restless legs syndrome. Results: The frequency of restless legs syndrome was found to be 12.4% in patients undergoing hemodialysis (10.5% in males versus 16% in females). The mean duration of hemodialysis was higher among RLS positive patients (12.88 +- 5.543 months) as compared to RLS negative patients (6.94 +- 4.610 months). Conclusion: RLS is a frequent, under-diagnosed co-morbidity in patients undergoing maintenance hemodialysis. (author)

  7. Infective endocarditis in chronic hemodialysis patients: Experience from Morocco

    Full Text Available 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 re-gular 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 Sta-phylococcus 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 Staphlococcus. 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.

    Full Text Available Erythropoietin resistance index calculation has been used as a tool to evaluate anemia response to erythropoietin therapy. Very little has been reported in its use when using darbepoetin and factors influencing in Arab patients. Darbepoetin resistance index (DRI was calculated in all our patients using darbepoetin. This was correlated to demographic, clinical, and laboratory parameters. Of the 250 patients, 40.4% were diabetic, 71.1% on hemodialysis, and 28.6% on hemodiafiltration, 23.9% with PermCaths (PC, and 76.1 % with arteriovenous fistula (AVF. The mean DRI was 10.96 ± 12.9 I. Females had 45% higher DRI than males (P = 0.005, and patients with PC had a 66% higher DRI than those with AVF (P = 0.029. Patients with Vitamin D level below the 50th percentile had 55.9% higher DRI than those above it (P = 0.05. DRI was negatively correlated with age (P = 0.018, dialysis vintage (P = 0.039, interdialytic weight gain P = 0.007, Vitamin D level, and serum albumin (P = 0.005 and positively correlate with parathyroid hormone (PTH level (P = 0.000. No impact was seen by the mode of dialysis, being diabetic, using anti-hypertensive therapy, body mass index, Kt/V, serum iron, total iron binding capacity, transferrin saturation, ferritin, C-reactive protein, Ca, or P. DRI in our Arab patients was comparable to erythropoietin resistance indices reported in other communities. Higher DRI was observed in females, PC users, lower serum albumin, lower Vitamin D, and shorter dialysis vintage. A negative correlation existed between DRI and age, dialysis vintage, interdialytic weight, and serum albumin and a positive correlation with PTH level.

    Nutritional status of hemodialysis (HD) patients is influenced by a multitude of factors and it strongly correlates with morbidity and mortality. The aim of this study was to investigate the influence of seasonal changes on nutritional status in maintenance HD patients. A selected population of 84 adult (40 females and 44 males, aged 68.98 ± 13.45 years) HD (5.94 ± 6.44 years) patients were investigated. Clinical, biochemical and nutritional parameters (BMI, creatinine, urea, serum albumin, total cholesterol and Dialysis Malnutrition Score (DMS) were measured in cold (January and December) and mild (June and September) months, altogether in 336 HD sessions. Statistically significant differences between cold and mild months were found in BMI (P = 0.046), creatinine before HD (P = 0.011), urea before HD (P ≤ 0.001), urea after HD (P ≤ 0.001) and glucose (P =  0.001). Differences between male and female patients in DMS, serum albumin and creatinine level in cold and mild months were found; where females altogether had higher DMS score and lower serum albumin and creatinine levels. These results suggest that seasonal variations of clinical and laboratory variables that reflect nutritional status occur commonly among maintenance HD patients and might lead to biases in the interpretation of results in clinical studies in which measurement schedules vary during the year. Also, results suggested that female HD patients may constitute an especially vulnerable population for seasonal oscillations of nutritional status. The reasons for most of these variations are not apparent and require further investigation. © 2016 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

    Full Text Available Objective: To compare the seropositivity of Toxoplasma gondii in a group of peritoneal dialysis patients with hemodialysis patients and a general local population as a control group in Tabriz, Northwest Iran. Methods: A total of 176 individuals were participated in the present study. Among them, 42 were peritoneal dialysis patients, 84 were hemodialysis patients and 50 were healthy volunteers. Anti-Toxoplasma immunoglobulin G and immunoglobulin M serologic study was administered on the collected serums and then the obtained data were analyzed using statistical methods. Results: In the present research, 70.2% of hemodialysis patients, 66.6% of peritoneal dialysis patients and 68% of control group had positive results for anti-Toxoplasma immunoglobulin G antibody. All individuals of the groups had negative serologic results for anti-Toxoplasma immunoglobulin M antibody. There was no significant difference between Toxoplasma gondii seropositivity in hemodialysis patients and peritoneal dialysis patients and general population (P > 0.05. Conclusions: The findings showed that either peritoneal dialysis or hemodialysis doesn’t increase the risk of Toxoplasma seropositivity in our region (Northwest Iran. It could be explained by the fact that the present research is carried out in a high seroprevalent area scale in which the majority of normal population had previous exposure to this parasitical infection.

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

    Due to high resting energy expenditure (REE) in maintenance hemodialysis patients, an increase in energy intake is usually recommended to improve their nutritional status. However, some patients appear to have poor appetite and low energy intake. In such patients low energy metabolism is expected. We hypothesized that in maintenance hemodialysis patients there are two types of the energy metabolism, high and low. This study was aimed at finding the energy metabolism in maintenance hemodialysis patients, especially in those with poor nutritional status. Subjects were hemodialysis out-patients (34 males and 20 females, mean age 59.1+/-10.7 y). REE was measured by an indirect calorimeter. Protein intake was obtained from normalized protein catabolic rate (nPCR), and physical activity level (PAL) was obtained by time study. Nutritional status assessed by serum albumin concentration was poor (3.7+/-0.2 g/dL) in spite of the adequate protein intake (1.1+/-0.3 g/kg per day). Only 11% of the subjects had appropriate serum albumin concentration. Mean REE was 24.6 kcal/kg per day which was lower than that of healthy Japanese (26.5 kcal/kg per day). REE and PAL positively correlated with serum albumin concentration (p<0.01). The results suggest that maintenance hemodialysis patients with poor nutritional status may have low REE.

    We examined the protein anabolic effects of Pro-Stat 64, a high nitrogen-containing, enzyme-hydrolyzed, tryptophan-fortified, collagen protein supplement administrated during hemodialysis, at two different dosing regimens. This was a randomized, controlled, prospective study with 3 different groups: control, single dose of supplementation, and double dose of supplementation. This study was performed at a clinical research center. Six prevalent chronic hemodialysis (HD) patients were enrolled: 5 males, 1 female, 4 African Americans, and 2 Caucasians. Their mean age was 45 +/- 11 years (S.D.). Two patients were diabetic. Protein turnover studies were performed using amino-acid (AA) balance and primed constant infusion of L-(1-(13)C) leucine. Whole-body protein balance was determined according to substrate kinetics. There were no statistically significant difference at any time point between protocols for blood chemistries and hormonal markers, except for minor variations in plasma glucose. All plasma AA groups displayed decreases during a control study, in which no supplementation was given. Compared with the control group, plasma nonessential AA and total AA concentrations were statistically significantly higher during HD after both single and double doses of supplementation. The forearm arteriovenous AA balance was statistically significantly better for essential, nonessential, and total AA uptake after both single-dose and double-dose supplementation compared with the control group, except for nonessential AA, which was significantly better only after a double dose. Whole-body protein breakdown and net protein balance were statistically significantly better during HD with a double-dose administration in a dose-dependent manner, compared with the control and single-dose groups. Oral AA supplementation alone improves whole-body and skeletal muscle protein anabolism in a dose-dependent manner in chronic HD patients. These data should be taken into account during

    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.

    Full Text Available Non-adherence to the therapeutic regimen is an increasingly growing problem especially among patients undergoing hemodialysis. The aim of this study was to modify the Greek version of Simplified Medication Adherence Questionnaire (GR-SMAQ for patients undergoing hemodialysis (GR-SMAQ-HD and explore its validity and reliability. Between June 2016 and November 2016 a group of patients undergoing hemodialysis (N=107 completed the Greek version of SMAQ. The study was carried out in three Dialysis Units of Hospitals of Athens and Peloponnese region, Greece. The form of GR-SMAQ was modified specifically for renal patients while four additional items were added so as the tool study all aspects of adherence to hemodialysis regimen. Construct validity was checked through exploratory factor analysis with principal Component Analysis with the Equamax method. Test-retest reliability and internal consistency were tested. Statistical analysis was performed using the IBM SPSS Statistics version 21. The significance level was set up at 5%. The Greek version of SMAQ for patients undergoing hemodialysis includes eight questions. Three factors emerged from factor analysis. Cronbach’s α coefficient was 0.742 for the whole scale and for each subscale was for Medication Adherence 0.75, for Attendance at hemodialysis session 0.856 and for Diet/Fluid restriction was 0.717. The total mean score was 6.29 (±1.82. GR-SMAQ-HD is a reliable and valuable tool that can be used by hemodialysis nurses and students of nursing for detection of adherence levels in clinical practice.

    Cardiovascular (CV) diseases are the main cause of death in maintenance hemodialysis (MHD) patients. Muscle wasting and physical function decline are common in MHD patients, and significantly impair their quality of life. These can result from abnormalities in cardiac function, which can be further worsened by physical deconditioning. Left ventricular diastolic function parameters were recently shown to be a better predictor of exercise capacity than systolic measures in patients with CV complications. But little is known about the relationship between cardiac function and physical function in MHD patients. In 82 MHD patients, left ventricular systolic dysfunction (LVSD) was assessed by ejection fraction and fractional shortening with echocardiography, and left ventricular diastolic dysfunction (LVDD) was assessed by pulse wave and tissue Doppler indices. Physical function was assessed by gait speed, performance on a shuttle walk test, and leg muscle strength. Dual-emission X-ray absorptiometry (DXA) was used to measure whole body lean mass (WBLM). The prevalence of LVDD and LVSD was 48.8 and 12.2%, respectively. Gait speed, shuttle walk time, leg strength, and WBLM% were significantly higher in the group without LVDD than with LVDD (p physical function or body composition between patients with and without LVSD. These data suggest that LVDD is more closely related to physical function and body composition than LVSD in MHD patients, and hence that LVDD may be an important therapeutic target.

    Anorexia is frequently found in end-stage renal disease and is a reliable predictor of morbidity and mortality in hemodialysis (HD) patients. The pathogenesis of anorexia is complex and the appetite-modulating hormone ghrelin could be involved. Two forms of circulating ghrelin have been described: acylated ghrelin (anorexic, and 20 patients (59%) non-anorexic. Energy intake (kcal/day) was significantly lower in anorexic than in non-anorexic patients (1,682 +/- 241 vs. 1,972.50 +/- 490; p anorexic than in non-anorexic patients (65.8 +/- 4.4 vs. 70.9 +/- 8.7; p = 0.05). Plasma des-acyl ghrelin levels (fmol/ml) were significantly higher in HD patients than in controls (214.88 +/- 154.24 vs. 128.93 +/- 51.07; p anorexic HD patients than in non-anorexic (301.7 +/- 162.4 vs. 159.1 +/- 115.5; p < 0.01). Anorexia is highly prevalent among HD patients and des-acyl ghrelin could be involved in its pathogenesis. Copyright 2007 S. Karger AG, Basel.

    In patients with hemodialysis-associated pneumonia (HDAP), information on both microbiologic features and antimicrobial strategies is limited. The aim of this study is to investigate predictive factors of infection with multidrug-resistant (MDR) pathogens in HDAP patients. This was a multicenter, retrospective, and observational study. Enrolled patients were classified into MDR or non-MDR pathogens groups according to culture results. We examined risk factors of infection with MDR pathogens and created a decision support tool using these risk factors. MDR pathogens were identified in 24 (22.8%) out of a total of 105 HDAP patients. The most common MDR pathogens were methicillin-resistant Staphylococcus aureus (10 patients, 9.5%) and the isolation rate of Pseudomonas aeruginosa was 6.6%. Logistic regression showed two variables were associated with the isolation of MDR pathogens: recent hospitalization (adjusted odds ratio [OR]: 2.951, 95% confidence interval [CI]: 1.022-8.518) and PSI (Pneumonia Severity Index) score (adjusted OR: 1.023, 95% CI: 1.005-1.041). The optimal cut-off value for PSI score using a receiver operating characteristic curve analysis was 147. According to the presence of 0, 1, or 2 of the identified risk factors, the prevalence of MDR pathogens was 7.6, 28.2 and 64.2%, respectively (p  147 are risk factors of infection with MDR pathogens in HDAP patients. This simple proposed tool would facilitate more accurate identification of MDR pathogens in these patients.

    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. © 2015 International Society for Hemodialysis.

    Maintaining long-term hemodialysis access in end-stage renal disease patients presents a serious challenge to surgeons. Over time, patients' remaining access sites diminish while complications and comorbidities simultaneously multiply; often resulting in the use of permanent tunneled catheters, which have a well-known high rate of complications and short-term usefulness. In this study, we report the results of a dialysis graft based on the axillary artery and ipsilateral axillary vein and tunneled in the subcutaneous tissues of the chest. We identified patients who had a chest wall arteriovenous graft (CWAVG) placed at our institution between May 2007 and December 2012. After institutional review board approval, the patients were retrospectively and then prospectively identified and followed for 2 years to document the performance, required maintenance, and complications of the graft. Sixty-seven grafts in 67 patients were reviewed, representing 0.56% of our 1,192 total dialysis access creations during the study period. The average patient was 55-year-old with an average history of 3.97 explicitly documented prior accesses. Sixty interventions were performed postoperatively including 32 for thrombosis and 28 for venous stenosis. Six documented graft infections occurred (9%). Three minor wound complications occurred, but the graft was preserved. Notably, no patient developed symptoms of steal syndrome. The primary and secondary patency rates at 1 and 2 years were 69.5% and 36.9% and 81.6% and 57.6%, respectively. Twenty-three of the 67 patients died in the 2-year follow-up period (34%). CWAVGs are useful and appropriate for patients with difficult upper extremity access. The patency rates for this "exotic" procedure are at least equivalent to other upper extremity grafts. The infection rate is lower than that for femoral grafts or tunneled catheters, and there is no risk of steal syndrome. CWAVGs can even be considered for primary use in patients who have

    End-stage renal disease patients who have been on long-term hemodialysis tend to develop central nervous system complications. The most common neurologic complications in this patient group include white matter changes, cerebral atrophy, osmotic demyelination syndrome, dialysis encephalopathy, hypertensive encephalopathy, intracranial hemorrhage, infarct, sinus thrombosis, and infection. Clinical evaluation of these patients is somehow complicated and MRI is important before establishment of the therapy. The purpose of this article is to illustrate the range of MRI findings of neurologic complications in end-stage renal failure patients on hemodialysis with etiologic factors. (orig.)

    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

    Full Text Available Vitamin D deficiency is fequently observed in chronic kidney disease. We conducted this study to determine the concentration of the above-mentioned parameters and the correlation between them in order to optimize therapy with vitamin D in patients with end-stage renal disease (ESRD on hemodialysis. In 53 patients on hemodialysis due to ESRD, vitamin D [Calcidiol (25(OHD], parathyroid hormone (PTH, calcium, phosphorus, albuminuria, albumin:creatinine ratio (ACR and other parameters have been followed up. Analysis of the levels of vitamin D has been carried out by High Performance Liquid Chromatography (HPLC, the PTH is determined by the system Centaur XP, Siemens Diagnostic, Electro-chemiluminescence immunoassay (ECLIA, and for albumin in urine we used immunological method [Miltigent microalbumin assay (Abbott Laboratories Diagnostics. We found out deficiency and insufficiency of vitamin D in 56.6% and 37.7%, as well as average 4.5 times increase in the PTH, hyperphosphatemia, hypocalcemia, albuminuria (A2 or A3, over 10 times increase in the ACR, secondary hyperparathyroidism. We registered a negative correlation between vitamin D and PTH. We confirmed the increase in creatinine and cystatin C in the patients on hemodialysis. There are few literature data for patients on hemodialysis, however, regarding the extent of the vitamin deficiency and its relationship with PTH, albuminuria, calcium, phosphorus, etc. Our data have indicated that patients on hemodialysis due to ESRD are associated with high incidence of vitamin D insufficiency or deficiency.

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

    Full Text Available 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.

    Full Text Available Objective: To understand the association of parathormone excess due to secondary hyperparathyroidism and hyperphosphatemia with coronary artery disease, a study was designed on a group of stable hemodialysis (HD patients. Methods: This cross-sectional study was carried out on patients undergoing maintenance HD. Blood samples were collected after overnight fasting for serum calcium, phosphorus, and intact serum parathormone (iPTH. The presence of cardiac chest pain was confirmed through the complaint of heart burn or epigastric pain, retrosternal discomfort and chest compression was confirmed by symmetrical depressed T wave at that time on a 12-lead ECG by means of a 12-channel and also reliving the pain after taking sublingual Trinitroglycerine pearls (TNG. Results: A sample of 36 stable HD patients was investigated. The mean age of patients was 46.5±17 years. The length of the time patients have been on hemodialysis were 32± 36 months (Median = 19 months. About 21% of patients had chest pain. Mean±SD of intact PTH of patients was 434±455 pg/ml (Median = 309 pg/ml. In this study, there was a significant difference of hemodialysis duration (p = 0.009, hemodialysis amount (p = 0.029 and also serum phosphorus (p = 0.013 between patients with and without cardiac chest pain. There was also a significant difference of iPTH (p = 0.026 between male hemodialysis patients with and without cardiac chest pain. Conclusion: Our data supported the importance of better control of serum phosphorus and also treatment of parathormone excess as the responsible factors promoting the coronary artery disease in hemodialysis patients.

    Full Text Available Background: Autonomic dysfunction (AD is highly prevalent in hemodialysis (HD patients and has been implicated in their increased risk of cardiovascular mortality. Objective: To correlate heart rate variability (HRV during exercise treadmill test (ETT with the values obtained when measuring functional aerobic impairment (FAI in HD patients and controls. Methods: Cross-sectional study involving HD patients and a control group. Clinical examination, blood sampling, transthoracic echocardiogram, 24-hour Holter, and ETT were performed. A symptom-limited ramp treadmill protocol with active recovery was employed. Heart rate variability was evaluated in time domain at exercise and recovery periods. Results: Forty-one HD patients and 41 controls concluded the study. HD patients had higher FAI and lower HRV than controls (p<0.001 for both. A correlation was found between exercise HRV (SDNN and FAI in both groups. This association was independent of age, sex, smoking, body mass index, diabetes, and clonidine or beta-blocker use, but not of hemoglobin levels. Conclusion: No association was found between FAI and HRV on 24-hour Holter or at the recovery period of ETT. Of note, exercise HRV was inversely correlated with FAI in HD patients and controls.

    Objective: To summarize the experience of the nursing care of indwelling catheter thrombolysis for acute thrombosis in the arteriovenous fistula in eight hemodialysis patients. Methods: After breaking thrombus through indwelling catheter, both bolus injection and micro-pump continuous infusion of urokinase was employed in eight hemodialysis patients with acute thrombosis in the arteriovenous fistula. The necessary nursing measures were carried out to assist the whole therapeutic procedure. Results: All the patients could well cooperate with the procedure of indwelling catheter thrombolysis and urokinase infusion. The reopening rate of the obstructed fistula was 100%. Conclusion: Indwelling catheter thrombolysis with urokinase infusion is a simple, effective and safe treatment for acute thrombosis in the arteriovenous fistula in hemodialysis patients. In order to obtain optimal results, necessary nursing measures must be carried out. (authors)

    Salicylate poisonings are common due to their multiple uses and wide availability. The variation of presenting symptoms contributes to inconsistent treatments in the emergency department. Patients with severe salicylate overdose require a high minute ventilation. Early in the course of an overdose, a patient will require hyperventilation. If they become too fatigued to compensate, mechanical ventilation may be needed. It can be impossible to recreate such a high minute ventilation with mechanical ventilation. This places patients at a high risk for decompensation and death. Hemodialysis is an effective elimination technique for salicylate overdose and should be considered early. All salicylate cases reported to the Illinois Poison Center were reviewed from 2003-2014. All intubated patients with a salicylate level >50mg/dl were included for analysis. Survival was compared to measured serum salicylate level and the administration of hemodialysis. 56 Cases were identified with an overall survival rate of 73.2% in patients with a serum salicylate level >50mg/dl. When patients did not receive hemodialysis, a peak salicylate level >50mg/dl had a 56% survival rate and 0% survival when the level was >80mg/dl. In the patients who received hemodialysis, a peak salicylate level >50mg/dl had a 83.9% survival rate and 83.3% survival when the level was >80mg/dl. Survival was decreased in these patients if hemodialysis was not performed. Mortality increases with the measured serum salicylate level. Timely hemodialysis for intubated salicylate overdose patients decreases mortality. Copyright © 2017 Elsevier Inc. All rights reserved.

    In patients with end-stage renal disease receiving conventional hemodialysis, both the frequency with which brief rises or falls in systolic blood pressure initiate concordant changes in pulse interval (arterial baroreflex effectiveness index), and the gain of reflex heart rate responses to these stimuli (arterial baroreflex sensitivity) are diminished. In chronic renal failure, low baroreflex effectiveness index and baroreflex sensitivity are associated with increased rates of all-cause mortality and sudden death, respectively. Conversion to home nocturnal hemodialysis augments baroreflex sensitivity but its effects on baroreflex effectiveness index have not been reported. In 20 consecutive hypertensive conventional hemodialysis patients training to transition to nocturnal hemodialysis (age 41 +/- 2 years; mean +/- standard error), baroreflex effectiveness index, baroreflex sensitivity (sequence method) and total arterial compliance (stroke volume/pulse pressure) were determined during quiet rest before and 2 months after conversion. With nocturnal hemodialysis, dialysis frequency doubled, the dose per session increased by 70% and antihypertensive medications were withdrawn (from 2.5 +/- 0.3 to 0.2 +/- 0.1 drugs/patient, P Baroreflex effectiveness index increased from (0.33 +/- 0.03 to 0.42 +/- 0.03, P = 0.01). Baroreflex sensitivity increased from 5.60 +/- 0.88 to 8.48 +/- 1.60 ms/mmHg (P baroreflex sensitivity (r = 0.63, P = 0.004) but not baroreflex effectiveness index (r = 0.05, P = 0.95), suggesting independent mechanisms for their attenuation and recovery in end-stage renal disease. Nocturnal hemodialysis increases baroreflex effectiveness index in addition to baroreflex sensitivity. The hypothesis that such changes might reduce cardiovascular event rates in this high-risk population merits prospective evaluation. More frequent engagement of the arterial baroreflex after conversion to nocturnal hemodialysis may improve short-term cardiovascular regulation.

    It is well established that there is a high incidence of cardiovascular diseases in hemodialysis patients, and involvement of oxidative stress has been hypothesised in these phenomena. Plasma norepinephrine is an independent predictor of many causes of mortality in general, and high norepinephrine levels predict cardiovascular complications in end stage renal disease. The aim of our study was to evaluate the potential link between vitamin C status, a marker of oxidative stress, and catecholamine concentrations before and after hemodialysis sessions. In a prospective study of 16 chronic hemodialysis patients, ascorbyl free radical levels were directly measured using electron spin resonance spectroscopy. These values were expressed with respect to vitamin C concentrations to obtain a direct index of oxidative stress. Vitamin C, epinephrine and norepinephrine were measured by high performance liquid chromatography. The data were examined for correlations between these compounds and clinical parameters including blood pressure and heart rates. In hemodialysis patients, ascorbyl free radical/vitamin C ratios increased significantly after dialysis. No differences were observed for catecholamine concentrations during hemodialysis sessions. In multivariate analysis, the ascorbyl free radical/vitamin C ratio did not correlate with epinephrine or norepinephrine levels. In our study, plasma norepinephrine and ascorbyl free radical/vitamin C ratios were not related among patients with end-stage renal disease. From these findings, we conclude that although these two factors are likely to be involved in the same causal pathway leading to cardiovascular events, it is likely that they seem to be independent.

  13. Modelling Transcapillary Transport of Fluid and Proteins in Hemodialysis Patients.

    Mauro Pietribiasi

    Full Text Available 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.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.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.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 fluid balance.

    Fetuin A - a predictor of cardiovascular (CV) outcomes in dialysis patients - is correlated with over-nutrition in the general population. Whether fetuin A and nutritional status interact with each other to alter CV outcomes and survival in hemodialysis (HD) patients remains unknown. We performed a prospective study on 388 prevalent HD patients. We used the geriatric nutritional risk index (GNRI) for the evaluation of nutritional status. Study outcomes included the occurrence of CV event, CV death, and all-cause mortality during follow-up; interactions between parameters for predicting outcomes were assessed by the interaction terms in a Cox regression model. Overall, 131 patients experienced CV events and 92 patients died, with 51 CV deaths. HD patients with higher fetuin A levels had lower numbers of CV events (adjusted hazard ratio [HR], 0.9; 0.81-0.99) and all-cause mortality (adjusted HR, 0.97; 0.91-0.99). However, patients with higher GNRI had lower all-cause mortality (adjusted HR, 0.79; 0.51-0.98, for every 10-unit increase). Fetuin A levels and GNRI showed a significant interaction in the prediction of CV events (adjusted HR, 1.01; 1.008-1.02) but not for all-cause or CV mortality. In patients with poor nutritional status, higher fetuin A levels were associated with fewer CV events; however, in contrast, in subjects with better nutritional status, higher fetuin A levels appeared to lead to a higher number of CV events. Fetuin A showed a remarkable interaction with nutritional status in evaluating the risks of CV morbidities in prevalent HD patients. © 2014 S. Karger AG, Basel.

    Bone metabolism disorder (BMD) and vascular dysfunction contribute to excess cardiovascular mortality observed in hemodialysis patients. Vascular dysfunction, a new marker of atherosclerosis, can play a role in this risk. Even though associated with higher mortality in the general population, such vascular evaluation in patients on hemodialysis has not been extensively studied. In this cross-sectional study, hemodialysis patients were submitted to flow-mediated dilation, subendocardial viability ratio (SEVR) and ejection duration index assessment, in order to estimate the impact of BMD markers on vascular dysfunction. A matched cohort of patients with (n = 16) and without (n = 11) severe secondary hyperparathyroidism (SHPT) was studied. Additionally, time spent under severe SHPT was also evaluated. Patients with severe SHPT had lower SEVR and higher ejection duration index, indicating higher cardiovascular risk. Lower SEVR was also associated to diastolic blood pressure (r = 0.435, p = 0.049), serum 25-Vitamin-D levels (r = 0.479, p = 0.028) and to more time spent under severe secondary hyperparathyroidism (SHPT), defined as time from PTH > 500pg/ml until parathyroidectomy surgery or end of the study (r = -0.642, p = 0.027). In stepwise multiple regression analysis between SEVR and independent variables, lower SEVR was independently associated to lower serum 25-Vitamin-D levels (p = 0.005), female sex (p = 0.012) and more time spent under severe SHPT (p = 0.001) in a model adjusted for age, serum cholesterol, and blood pressure (adjusted r² = 0.545, p = 0.001). Subendocardial perfusion was lower in patients with BMD, reflecting higher cardiovascular risk in this population. Whether early parathyroidectomy in the course of kidney disease could modify such results still deserves further investigation.

    Full Text Available Secondary hyperparathyroidism (SHPTH can develop early in the course of chronic renal failure and becomes more prominent as kidney function declines. We studied the effect of diabetes, age, and dialysis on parathyroid function in 60 (21 women, 39 males; 44 non-diabetic, 16 diabetic hemodialysis (HD patients. Serum intact PTH (iPTH, calcium, phosphorus, alkaline phosphatase (ALP, and magnesium (Mg were measured. Adequacy of HD was evaluated by calculating the urea reduction rate (URR. There were significantly lower values of serum iPTH, ALP, and dialysis adequacy among diabetic than non-diabetes HD patients. In addition, there were an inverse correlation of age and serum iPTH (r= -0.27, p= 0.034 as well as age and serum phosphorus (r= -0.28, p= 0.031. There was also a positive correlation between serum iPTH with the duration (r= 0.001, p=0.42 and doses of dialysis treatment (r= 0.38, p= 0.002. We conclude that a significant negative correlation between age and serum phosphorus and lower parathyroid activity in diabetic HD patients, which implies more prevalence of bone disease in elderly diabetic HD patients. Further study of bone disease in this group of patients is required to evaluate its effect on outcome and different therapeutic interventions.

    The aim of this study was to evaluate the effect of hemodialysis (HD) duration on food intake and nutritional markers in patients with chronic kidney disease (CKD). Twenty CKD patients received maintenance HD over a 9-year period. At the beginning of the study (T0) and at 3-year intervals (T1, T2, and T3) during the 9-year follow-up, a nutritional survey using the 24-h recall and record method was repeated for 4 days, and the blood samples were drawn. The results from T0 were used as references. Nutritional status was assessed through food intake, nutritional markers (urea, uric acid, creatinine, cholesterol, total protein, and albumin), and anthropometric measurements (height, dry weight, and body mass index). HD duration was correlated with energy intake (r = -0.89, P protein intake (r = -0.50, P intakes were noted in patients at T1 (-8%), T2 (-38%), and T3 (-59%) with decreased fiber intakes. Lipid intake was diminished by 11, 17, and 25% in patients, respectively, at T1, T2, and T3. The consumption of milk and dairy products, meats, fish, eggs, fruits, vegetables, and fat was reduced at T1, T2, and T3. In conclusion, long-term HD fails to correct undernutrition caused by CKD. Long-term dialysis complications could be reduced with preventive measures, including the use of biocompatible membranes and high-dose dialysis. Consequently, patients could experience a decreased prevalence of protein-energy malnutrition.

    Background and objectives: Low serum testosterone levels in hemodialysis (HD) patients have recently been associated with cardiovascular risk factors and increased mortality. To confirm this observation, we investigated the predictive role of serum total testosterone levels on mortality in a large group of male HD patients from Turkey. Design, settings, participants, & measurements: A total of 420 prevalent male HD patients were sampled in March 2005 and followed up for all-cause mortality. Serum total testosterone levels were measured by ELISA at baseline and studied in relation to mortality and cardiovascular risk profile. Results: Mean testosterone level was 8.69 ± 4.10 (0.17 to 27.40) nmol/L. A large proportion of patients (66%) had testosterone deficiency (10.1 nmol/L; 64 versus 81%; P = 0.004). A 1-nmol/L increase in serum testosterone level was associated with a 7% decrease in overall mortality (hazard ratio 0.93; 95% confidence interval 0.89 to 0.98; P = 0.01); however, this association was dependent on age and other risk factors in adjusted Cox regression analyses. Conclusions: Testosterone deficiency is common in male HD patients. Although testosterone levels, per se, predicted mortality in this population, this association was largely dependent on age.

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

    Full Text Available Introduction: Presently, bacteremia is the principal cause of morbidity in patients undergoing hemodialysis. Gram-negative bacteria account for approximately 50 percent of documented infections. Endotoxins released during lysis of gram negative bacteremia result in inflammatory and defense response by the body and if not treated promptly result in septic shock and ultimately death of the patient. This study describes the detection of endotoxins in blood of patients with bacteremia due to gram - negative bacteria by LAL test. Method: Blood samples of 278 hemodialysis patients were analyzed in this study and pathogens were isolated from blood culture samples. Then, their antibiotic sensitivity was determined. In patients with positive blood culture, endotoxin levels were measured by LAL-test. Results: Frequency of bacteremia in patients was 13.6% . The prevalence of gram – negative bacteremia was 44.7%. E coli were the major pathogens, while staphylococcus aureus was the most common gram positive bacterium. Endotoxin was detected in 15 patients (3.8 ± 1.08 EU/ml . The sensitivity and specificity of endotoxins for gram – negative bacteremia were 88% and 95%, respectively. Conclusion: The results indicate that the LAL method is a fast, sensitive and simple method. There was no significant difference between the results of blood culture and LAL – test ( P > 0.05 .

    Chronic subclinical volume overload occurs very frequently and may be ubiquitous in hemodialysis (HD) patients receiving the standard thrice-weekly treatment. It is directly associated with hypertension, increased arterial stiffness, left ventricular hipertrophy, heart failure, and eventually, higher mortality and morbidity. We aimed to assess for the first time if the relationship between bioimpedance assessed overhydration and survival is maintained when adjustments for echocardiographic parameters are considered. A prospective cohort trial was conducted to investigate the impact of overhydration on all cause mortality and cardiovascular events (CVE), by using a previously reported cut-off value for overhydration and also investigating a new cut-off value derived from our analysis of this specific cohort. The body composition of 221 HD patients from a single center was assessed at baseline using bioimpedance. In 157 patients supplemental echocardiography was performed (echocardiography subgroup). Comparative survival analysis was performed using two cut-off points for relative fluid overload (RFO): 15% and 17.4% (a value determined by statistical analysis to have the best predictive value for mortality in our cohort). In the entire study population, patients considered overhydrated (using both cut-offs) had a significant increased risk for all-cause mortality in both univariate (HR = 2.12, 95%CI = 1.30-3.47 for RFO>15% and HR = 2.86, 95%CI = 1.72-4.78 for RFO>17.4%, respectively) and multivariate (HR = 1.87, 95%CI = 1.12-3.13 for RFO>15% and HR = 2.72, 95%CI = 1.60-4.63 for RFO>17.4%, respectively) Cox survival analysis. In the echocardiography subgroup, only the 17.4% cut-off remained associated with the outcome after adjustment for different echocardiographic parameters in the multivariate survival analysis. The number of CVE was significantly higher in overhydrated patients in both univariate (HR = 2.46, 95%CI = 1.56-3.87 for RFO >15% and HR = 3.67, 95%CI = 2

    Full Text Available Aim: To determine the prevalence and the type of complementary and alternative medicine (CAM use among chronic kidney disease (CKD patients on maintenance hemodialysis (MHD. Materials and Methods: The study was conducted in 200 CKD patients who were on MHD. The patients were subjected to a validated interviewer-administered questionnaire adopted from the National Health Interview Survey Adult CAM. The knowledge on CAM and its usage by the patients were assessed based on the responses given by the patients. Results: Of the 200 patients, 52 (26% patients were identified to be using CAM therapy. The most commonly used CAM modality by these patients was Ayurveda both alone (30.4% and in combination with other CAM modalities (23.2%, followed by acupuncture in 17.3% patients. CAM usage was high in the age range of 50–64 years (67%. Of the CAM users, 21% of patients were from a rural area; 16.5% of patients were from upper middle class, and 24% were on dialysis for 1–4 years. There was a statistically significant association between CAM usage and age, gender, place of living, socioeconomic status, and duration of dialysis (P < 0.01. Conclusion: The present survey provides the data on the usage of CAM among dialysis patients and adds to the increasing evidence about CAM use. Because many products are at risk to either accumulate or cause interactions with medication, a better education on the risks and benefits of the CAM therapy by the health care providers to the end stage renal disease patients is needed.

    Retention of β 2-microglobulin in patients undergoing hemodialysis is associated with a β 2-microglobulin-derived amyloidosis. Removal of β 2-microglobulin by renal replacement therapy has been proposed for the prevention of this amyloidosis. Currently, however, data on the β 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 β 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 β 2-microglobulin steady state plasma concentration (plus β 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 ± 12.8 ml/min (mean ± SD) versus 3.4 ± 0.7 ml/min). In contrast, the β 2-microglobulin synthesis rate in the patient group (3.10 ± 0.79 mg/kg/day) was not significantly different from that of normal controls (2.40 ± 0.67 mg/kg/day), which was due to markedly elevated β 2-microglobulin plasma concentrations in the patients (37.6 ± 14.1 mg/L vs 1.92 ± 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

    Full Text Available The (prorenin receptor [(PRR] is cleaved by furin to generate soluble (PRR [s(PRR], 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(PRR levels and background factors, including indices of atherosclerosis, in hemodialysis patients. Serum s(PRR levels were measured in hemodialysis patients and clearance of s(PRR through the membrane of the dialyzer was examined. Furthermore, relationships between serum s(PRR levels and background factors were assessed. Serum s(PRR 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(PRR and creatinine were 56.9 ± 33.5 and 147.6 ± 9.50 ml/min, respectively. Serum s(PRR 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(PRR levels was observed even after correction for age, history of smoking, HbA1c, and LDL-C. Serum s(PRR levels were significantly higher in hemodialysis patients when compared with subjects with normal renal function, although s(PRR is dialyzed to some extent, but to a lesser extent than creatinine. High serum s(PRR levels may be associated with atherosclerosis independent of other risk factors, suggesting that serum s(PRR could be used as a marker for atherosclerotic conditions in hemodialysis patients.

    Cardiovascular disease is the major cause of mortality and morbidity in dialysis patients. Recently, circulating endotoxin is found to associate with the systemic inflammatory state and cardiovascular disease of dialysis patients. Previous studies showed that the use of ultrapure dialysate for hemodialysis could reduce the exposure to exogenous endotoxin. We studied the effect of using ultrapure dialysate for hemodialysis on circulating endotoxin and bacterial DNA fragment levels and vascular stiffness. This is an open-labeled prospective study of 25 patients (14 male). Circulating endotoxin and bacterial DNA level, vascular stiffness as represented by arterial pulse wave velocity (PWV), nutrition and hydration status were monitored before and repeatedly throughout 12 months after the use of ultrapure dialysate for hemodialysis. The average age was 58.9 ± 10.2 years; 21 patients completed the study. Within 4 weeks of conversion to ultrapure dialysate for hemodialysis, the plasma endotoxin level fell from 0.302 ± 0.083 to 0.209 ± 0.044 EU/ml (p hemodialysis patients, circulating endotoxin level is associated with vascular stiffness and systemic inflammation. Using ultrapure dialysate for hemodialysis effectively reduces circulating endotoxin level in hemodialysis patients. The long-term benefit of using ultrapure dialysate for hemodialysis requires further study. © 2013 S. Karger AG, Basel.

    Full Text Available Cardiovascular disease is the main cause of death among patients with end-stage renal disease (ESRD. The present study was undertaken to identify the main cardiovascular diseases and their risk factors in 160 patients with ESRD on hemodialysis (HD in Brazil. Their mean age was 47 ± 39 years. The main risk factors for cardiovascular diseases were arterial hypertension (89.4%, dyslipidemia (78.3%, low high-density lipoprotein levels (84.2% and low physical activity (64.1%. Family history of coronary insufficiency and high low-density lipoprotein levels were significantly associated with coronary artery disease (P = 0.005 and P = 0.029, respectively. Sedentary life style, diabetes mellitus, secondary hyperparathyroidism and hyperglycemia also showed a significant association with the underlying vascular disease (P = 0.017, P = 0.039, P = 0.037 and P = 0.030, respectively. Hypercalcemia, hypertension and black race were factors significantly associated with left ventricular systolic dysfunction (P = 0.01, P = 0.0013 and P = 0.024, respectively. Our study shows that the most prevalent cardiovascular diseases in patients with ESRD were left ventricular hypertrophy, atherosclerotic disease, valvular disease and coronary artery disease. Hypertension and dyslipidemia were the common risk factors associated with cardiovascular diseases. The present study was undertaken to identify the main cardiovascular diseases and their risk factors in 160 patients with ESRD on HD in a single center in Brazil.

    Hemodialysis (HD) patients with peripheral vascular disease (PVD) are at higher risk of mortality. The main objectives of this work were to investigate the hypothesis of an association between the PVD and an altered control system on peripheral resistance in response to volume depletion induced by HD treatment; and to investigate whether HD induced increase of pulse pressure (PP) is associated with PVD. Continuous blood pressure (BP) was recorded during HD treatment at the beginning and at the end of HD. The overhydration condition was evaluated by means of whole body bioimpedance spectroscopy, measured before each HD treatment. BP variability, heart rate variability and baroreflex sensitivity were then analyzed. Patients affected by PVD reported a prevalence of peripheral local control as shown by higher values of very low frequency in diastolic blood pressure (DBP) variability and a reduced cardiac baroreflex with respect to patients not affected by this pathology. HD treatment induced a significant increase of PP and LF% in DBP series in PVD patients only. Our results suggested that differences in BP variability and PP changes could be related not only to an underlying vascular disease, but also to an alteration in autonomic control. (paper)

    Full Text Available Abstract Objective Poor adherence to complex multimodal therapies is a widely recognized problem in the daily care of dialysis patients, contributing to excess morbidity and mortality of this population. While a few studies have been devoted to understanding patient nonadherence, their results were somewhat controversial. The goals of this review are to quantify nonadherence to certain oral medications, to raise awareness of factors that may cause problems in a patient's adherence to this treatment, and to describe strategies that may be used to improve adherence to prescribed pharmacotherapy. Methods A systematic literature review in the MEDLINE and PubMed database (1971-2008 was performed. Quantitative studies, which accurately indicated the total percentages of nonadherence to oral medication in adult patients receiving chronic hemodialysis, were identified. Results A total of 19 studies fulfilled the search criteria. Rates of nonadherence to the oral medication ranged from 3 - 80%. More than half of the included studies reported nonadherence rates of ≥ 50% (mean 67%. The use of phosphate binding therapy was the prevalent surveyed oral medication. Self reports, structured interviews, and predialysis serum phosphate levels were the most frequent assessment tools used to record adherence rates. Limitations of the reviewed studies included small patient cohorts, inconsistent definitions of adherence, and a lack of standardized methods for measuring nonadherence. Conclusions Nonadherence to oral medication in hemodialysis patients is still an underestimated, but life-threatening behaviour.

    The influenza virus is one of the most common causes of viral respiratory tract infections. Some chronic diseases predispose to a severe course of the disease and increase the risk of complications and death. To minimize the risk of infection and complications, care of patients with increased risk should include prophylactic measures such as the administration of a seasonal influenza vaccine. An influenza vaccine is the best and cheapest method of influenza prevention. It is indicated for patients with chronic kidney disease, both during conservative treatment and renal replacement therapy. Many studies that have assessed the efficacy of an influenza vaccine in patients on hemodialysis have found that immune deficiency predisposes these patients to infection and a severe course of the disease. Because the immune response to a standard influenza vaccine in this population is weak, the studies covered many aspects of vaccination, including the need for a booster dose. Unlike in a healthy population, the efficacy of an influenza vaccine in patients on hemodialysis might be insufficient; however, the vaccine is still able to induce immunity in a significant number of patients. Considering the latest data and the results of studies described above, the recommendation of a seasonal influenza vaccine should be obligatory in all hemodialysis patients. This paper is based on original articles available from Medline database. The most recent and most significant literature on the influenza vaccine in patients on hemodialysis has been reviewed.

    Background. Protein intake in hemodialysis patients can be estimated indirectly from the protein equivalent of total nitrogen appearance (PNA) during the interdialytic period. A reliable estimate of the patient's urea distribution volume (UDV) is required to assess protein intake from PNA values.

    Full Text Available Diabetic ketoacidosis (DKA is a critical complication of type 1 diabetes associated with water and electrolyte disorders. Here, we report a case of DKA with extreme hyperkalemia (9.0 mEq/L in a patient with type 1 diabetes on hemodialysis. He had a left frontal cerebral infarction resulting in inability to manage his continuous subcutaneous insulin infusion pump. Electrocardiography showed typical changes of hyperkalemia, including absent P waves, prolonged QRS interval and tented T waves. There was no evidence of total body water deficit. After starting insulin and rapid hemodialysis, the serum potassium level was normalized. Although DKA may present with hypokalemia, rapid hemodialysis may be necessary to resolve severe hyperkalemia in a patient with renal failure.

    Aim To compare finding of thyroid gland scintigraphy with serum concentration of parathyroid hormone in patients undergoing hemodialysis. Methods This retrospective-prospective study included 50 patients undergoing hemodialysis with established hyperparathyroidism who were treated at Cantonal Hospital Zenica in the period 2009 - 2014. Besides anthropological data, concentration of parathyroid hormone in serum of patients was monitored too. Scintigraphy was performed at the Department of Nuclear Medicine using two-headed gamma camera Prism 2000xp. Results Of the total number of 50 patients, 24 (48%) were males and 26 (52%) were females. The average age was 49.34±11.82 years. A total of 17 (34%) patients had normal findings of scintigraphy, 11 (22%) had mildly pronounced uptake of radiopharmaceuticals (score of 1), 14 (28%) had moderately pronounced uptake (score of 2), and eight (16%) had intensive uptake of radiopharmaceuticals (score of 3). A statistically significant difference was established in the length of hemodialysis treatment and scintigraphy finding (p=0.041). Conclusion Scintigraphy of parathyroid glands in patients undergoing hemodialysis allows us to select them for parathyroidectomy. Scintigraphy of parathyroid glands and a value of parathormone in serum should be incorporated into the test algorithm for patients with secondary hyperparathyroidism caused by chronic kidney disease.

    Full Text Available The progressive loss of kidney function is accompanied by metabolic acidosis. The relationship between metabolic acidosis, nutritional status, and oral bicarbonate supplementation has not been assessed in the Indian chronic kidney disease (CKD population who are on maintenance hemodialysis (MHD. This is a single-center prospective study conducted in the Western part of India. Thirty-five patients, who were receiving MHD were assessed for metabolic acidosis along with various nutritional parameters at the baseline and at the follow-up after 3 months, postcorrection of acidosis with oral sodium bicarbonate supplements. The relationship between the correction of metabolic acidosis with oral bicarbonate supplements and changes in dietary and various nutritional parameters were evaluated. Metabolic acidosis at the baseline evaluation was found in 62.86% cases of the cohort with a mean serum bicarbonate value of 20.18 ± 4.93 mmol/L. The correction of acidosis with increment in the mean dosage of oral sodium bicarbonate supplements from 0.69 ± 0.410 mmol/kg/day at baseline to 1.04 ± 0.612 mmol/kg/day, significantly reduced the prevalence of metabolic acidosis to 23.33% cases at the follow-up. Improvement in serum bicarbonate level showed significant dietary, anthropometric, and nutritional improvements in these patients. Hence, we conclude that correction of metabolic acidosis with optimal oral bicarbonate supplementation plays a pivotal role in the treatment of malnourished CKD patients on MHD.

In the present study, we investigated the factors, especially the duration of HD, associated with insomnia in HD patients.Patients and methods: A total of 138 patients undergoing HD were recruited, and the Japanese version of the Pittsburgh Sleep Quality Index (PSQI was used to assess the quality of sleep. Subjects with a total PSQI score up to 4 and those with a score of at least 5 were identified as normal subjects and subjects with insomnia, respectively. Additionally, we assessed restless legs syndrome, depression using the Center for Epidemiologic Studies Depression Scale, and health-related quality of life (QOL using the Short Form 8 Health Survey. We divided the subjects into two groups according to the median HD duration.Results: The prevalence rate of insomnia was 54.3% among all the subjects. Twenty-one subjects (15.2% had depression, 26 (18.8% had restless legs syndrome, and 75 (54.3% had insomnia. The median HD duration was 4 years. The scores of components 1 and 4 of the PSQI, subjective sleep quality and habitual sleep efficiency, did not show a significant difference between the normal and insomnia groups.

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

    To investigate the oxidative stress and its association with antioxidants in patients on hemodialysis, we evaluated the levels of albumin, C-reactive protein (CRP), ferritin, vitamin E, glutathione, and total antioxidant capacity in these patients. In a cross-sectional study, we enrolled 25 patients on maintenance hemodialysis and measured the inflammatory and oxidative stress indicators consisting of the plasma concentrations of glutathione, vitamin E, and total antioxidant capacity. The acute-phase inflammatory response was assessed by determining the serum levels of CRP and albumin as well as the plasma level of ferritin. Antioxidants and acute-phase reactants in men and women and their association with age and their correlations with each other were analyzed. The mean age of the patients was 53.6 +/- 14.1 years (range, 29 to 70 years). They had been on hemodialysis for a mean duration of 4.66 +/- 5.08 years. There were no association of sex or age with the levels of antioxidants and acute-phase reactants. Plasma level of glutathione significantly correlated with CRP (r = 0.48; P = .01) and serum albumin (r = 0.42; P = .04). Duration of dialysis did not correlate with the antioxidants or acute-phase reactants. Although it is reasonable to see an association between acute-phase reactants and levels of antioxidants in patients on hemodialysis, we failed to show such a relation. It is recommended that other biomarkers of oxidative stress and their relation in patients with kidney failure be investigated.

    The aim of this study was to evaluate psychological distress in patients on chronic hemodialysis. A total of 72 patients on chronic hemodialysis were enrolled in this study. We evaluated psychological distress by using the K6 questionnaire, health-related quality of life (HRQOL) by using the EQ-5D questionnaire, and clinical parameters. Among the 72 patients, we also evaluated changes in K6 scores in 58 patients at 1-year follow-up. The mean K6 score was 3.7 ± 3.7 and 2 subjects (2.8%) were defined as having psychological distress. K6 scores were significantly correlated with body fat percentage, albumin level, and EQ-5D scores in total subjects. K6 scores were also significantly and negatively correlated with EQ-5D scores in men and women. In the 1-year follow-up group, changes in K6 scores were weakly and negatively correlated with changes in EQ-5D scores. Psychological distress was closely associated with HRQOL in patients on chronic hemodialysis. Coping strategies for psychological distress might be useful in improving HRQOL in patients on hemodialysis.

    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.

    Wegener's granulomatosis is a serious autoimmune disorder characterized by necrotizing small-vessel vasculitis. It is a multisystem disease that primarily affects the lung and kidneys. Previous studies indicated few relapses of vasculitis after hemodialysis due to uremic immunosuppression. Our case report describes an end-stage renal failure patient who had developed non-caseating lung granulomata with giant cell formation and fibrinoid necrosis of arterial media that is consistent with Wegner's granulomatosis for the first time and eight years after initiation of maintenance hemodialysis. We believe that such a phenomenon has rarely been reported.

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

    An effective approach to prevent hemodialysis vascular access dysfunction is still unclear despite previous studies, which have shown conflicting results of several drugs on vascular access outcomes. In this study, we focused on diabetic hemodialysis patients with native arteriovenous fistula and evaluated the impact of statin treatment on vascular access patency. A retrospective cohort study of 268 consecutive patients who newly started hemodialysis due to diabetic nephropathy between January 2011 and December 2013 at Japan Community Health Care Organization Sendai Hospital was performed and the patients were followed for two years. The primary outcome was vascular access dysfunction. Effect of statin treatment was examined using Kaplan Meier analysis and Cox proportional hazard, after adjusting for covariates. The mean follow-up period was 426.7 days, and 117 (52.2%) patients developed vascular access dysfunction. The two-year patency rate was 55.0% among statin users and 36.1% in non-users. Vascular access survival period was significantly longer among statin users (log-rank test, p = 0.004). In multivariable analysis, statin treatment is significantly associated with better vascular access outcomes, in which the hazard ratio was 0.71 (95% CI, 0.52 to 0.97; p = 0.028) in the unadjusted model and 0.63 (95% CI, 0.45 to 0.88; p = 0.007) after adjustment for covariates. Statin treatment could be associated with improved vascular access dysfunction among diabetic hemodialysis patients.

    People with end-stage kidney disease treated with dialysis experience high rates of premature death that are at least 30-fold that of the general population, and have markedly impaired quality of life. Despite this, interventions that lower risk factors for mortality (including antiplatelet agents, epoetins, lipid lowering, vitamin D compounds, or dialysis dose) have not been shown to improve clinical outcomes for this population. Although mortality outcomes may be improving overall, additional modifiable determinants of health in people treated with dialysis need to be identified and evaluated. Oral disease is highly prevalent in the general population and represents a potential and preventable cause of poor health in dialysis patients. Oral disease may be increased in patients treated with dialysis due to their lower uptake of public dental services, as well as increased malnutrition and inflammation, although available exploratory data are limited by small sample sizes and few studies evaluating links between oral health and clinical outcomes for this group, including mortality and cardiovascular disease. Recent data suggest periodontitis may be associated with mortality in dialysis patients and well-designed, larger studies are now required. The ORAL Diseases in hemodialysis (ORAL-D) study is a multinational, prospective (minimum follow-up 12 months) study. Participants comprise consecutive adults treated with long-term in-center hemodialysis. Between July 2010 and February 2012, we recruited 4500 dialysis patients from randomly selected outpatient dialysis clinics in Europe within a collaborative network of dialysis clinics administered by a dialysis provider, Diaverum, in Europe (France, Hungary, Italy, Poland, Portugal, and Spain) and South America (Argentina). At baseline, dental surgeons with training in periodontology systematically assessed the prevalence and characteristics of oral disease (dental, periodontal, mucosal, and salivary) in all participants

    Full Text Available Background: Prevalence of End Stage Renal Disease (ESRD is increasing in the world. Because of clinical importance of ESRD and absence of significant data, we studied the epidemiology of end stage renal failure in patients under hemodialysis in Lorestan province. Material and methods: This descriptive cross sectional study was carried out between January 2012 and January 2013 in dialysis centers of Lorestan university of medical sciences .Subject were selected by census method and data galhered using a questionnaire. At the end, collected data were analyzed by SPSS software, descriptive statistics and Chi-square test. Results: All the patients under hemodialysis were 318 cases, 182 out of them (57.2% and 136(42.8% were male and female respectively. The mean age of the subjects was 53.2± 16.4 years. The cause of renal failure in 38.1% of the patients were hypertension, diabetes (19.2% and unknown factors (27.4%. As well as 5.97% of the patients infected by HCV, HBV or HIV . A significant statistical difference was observed between causes of chronic renal failure and different ages of the subjects (p=0.002. Conclusion: Augmentation of screening programs and especially, early referral of high risk subjects to nephrologists is recommended for prevention of end stage renal disease.

    Full Text Available Background: Patients with end-stage renal disease (ESRD have a high rate of hospitalization and are prone to care gaps that may occur during the transition from hospital to home. The virtual ward (VW is an innovative model that provides short-term transitional care to patients upon hospital discharge. The VW may be an effective intervention to address care gaps. Objectives: The primary objective of the pilot study was to assess the feasibility and practicality of implementing the Home Dialysis VW (HDVW on a broader scale. Design: The HDVW Pilot Study enrolled home hemodialysis patients following one of four inclusion criteria: 1. Discharge from hospital, 2. Completion of an in-hospital medical procedure, 3. Prescription of an antibiotic, 4. Completion of home hemodialysis training. Patients were followed in the HDVW for 14 days and during this time were assessed serially with a clinician-led telephone interview for one of three transitional care gaps: 1. Requirement for change in hemodialysis prescription, 2. Requirement for coordination of follow-up care, 3. Requirement for medication change. Setting: The study was conducted in Toronto, Ontario, Canada at a quaternary care academic teaching hospital from 2012–2013. Patients: This study included 52 HDVW admissions among 35 patients selected from the existing home hemodialysis program. Measurements: The primary outcome was the identification of the number of care gaps at each HDVW admission. Secondary outcomes included the identification of potential predictors of care gaps and description of clinical adverse events following HDVW admission (readmissions, emergency department visits, unplanned visits to the home hemodialysis in-center.

    Full Text Available In the patients with end-stage renal disease (ESRD with hepatitis B virus (HBV infection who underwent hemodialysis, the viral load of HBV DNA is relatively low and stable. For this phenomenon, some studies suggest that hemodialysis can reduce the HBV DNA load. The mechanism, which remains unclear, may be as follows: when HBV DNA enters the dialysate through the dialysis membrane, it was adsorbed onto the dialysis membrane; some virus particles were destroyed, and antiviral substances were produced in the course of hemodialysis. At present, there is no consensus on the mechanism responsible for the influence of maintained hemodialysis on the viral load of HBV DNA. This article reviews the factors involved in the influence of maintained hemodialysis on the viral load in ESRD patients with HBV infection and the recent progress.

    Acute renal failure induced by contrast media is an important problem in renal insufficiency patients. Prophylactic hemodialysis is usually undertaken after the administration of radiocontrast media. However, we decided to cease giving prophylactic hemodialysis from February, 2002 in line with the guidelines regarding dialysis and contrast media administration provided by the European Society of Urogenital Radiology. We reported our policy at the doctor's meeting of hemodialysis therapy and at the meeting of clinical engineering technologists which were held in Okinawa. After the presentation, a questionnaire survey in 28 hospitals was undertaken by telephone. In all the hospitals, prophylactic hemodialysis after the administration of radiocontrast media was still being continued, with the exception of one hospital. We need to enlighten medical staff that the strategy of performing hemodialysis immediately after the administration of contrast media in patients with reduced renal function does not diminish the rate of radiocontrast media-induced nephropathy.

    Full Text Available Introduction. One of the characteristic signs of uremic syndrome is anemia. One of major factors that affects on severity of anemia in ESRD is underlying diseas. The porpuse of this study is to compaire anemia between diabetic and non diabetic ESRD patients. Methods. In a case control study we compared the mean valuse of Hb, Het, MCV, MCH, MCHC, BUN, Cr and duration of dialysis between diabetic and nondiabetic patients on chronic hemodialyis. some variables (such as age, sex, use of erythropoietin, nonderolone decaonats, folic acid, ferrous sulfate, transfusion and blood loss in recent three months and acquired kidney cysts were matched between cases and controls. Results. Means of Hb were 9±1.3 and 8 ± 1.7 in diabetic and non diabetic patients (P<0.05. Mean corposcular volume in diabetic patients (91±3.1 fl was more higher than non diabetic ones (87.1 ± 8.9 (P < 0.05. Other indices had no differences between two groups (P > 0.05. Discussion. Severity of anemia in patients with diabetic nephropathy is milder that other patients with ESRD. So, Anemia as an indicator of chronocity of renal disease in diabetics is missleading.

    Dialysis patients have a high risk for inadequate nutrition. Their nutritional status is particularly susceptible to deterioration when faced with intercurrent events such as hospitalization. This study was conducted to improve the understanding of the temporal evolution of nutritional parameters as a foundation for rational and proactive nutritional intervention. A retrospective cohort study was performed to investigate the temporal evolution of nutritional parameters (serum albumin, serum phosphate, serum creatinine, equilibrated normalized protein catabolic rate, and interdialytic weight gain) and a composite nutritional score derived from these parameters, in two populations: (1) incident hemodialysis (HD) patients who started HD between January 2006 and December 2011 and were followed for up to 54 months (median 16.3), and (2) prevalent patients with HD vintage ≥2.5 years who were hospitalized between January 2006 and December 2011 and followed from 6 months before to 6 months after hospitalization. In incident patients (n=126,964), each of the nutritional parameters improved after HD initiation, with a mean composite nutritional score at the 24th percentile at the start of HD and reaching a plateau at the 57th percentile toward the end of the second year on dialysis. Nutritional parameters increased more rapidly and reached higher values among patients who survived longer. In hospitalized patients (n=14,193), the nutritional parameters and the composite score began to decline 1-2 months before hospitalization, reached their lowest level in the month after hospitalization, and then partially recovered in the subsequent 5 months. The degree of recovery of the nutritional score was inversely related to the number of rehospitalizations. This study increases the understanding of nutritional resilience and its determinants in HD patients. Application of the nutritional score, pending further validation, may facilitate targeted and timely interventions to avert

    Protein-Energy Wasting (PEW) is the depletion of protein/energy stores observed in the most advanced stages of Chronic Kidney Disease (CKD). PEW is highly prevalent among patients on chronic dialysis, and is associated with adverse clinical outcomes, high morbidity/mortality rates and increased healthcare costs. This narrative review was aimed at exploring the pathophysiology of PEW in end-stage renal disease (ESRD) on hemodialysis. The main aspects of nutritional status evaluation, intervention and monitoring in this clinical setting were described, as well as the current approaches for the prevention and treatment of ESRD-related PEW. An exhaustive literature search was performed, in order to identify the relevant studies describing the epidemiology, pathogenesis, nutritional intervention and outcome of PEW in ESRD on hemodialysis. The pathogenesis of PEW is multifactorial. Loss of appetite, reduced intake of nutrients and altered lean body mass anabolism/catabolism play a key role. Nutritional approach to PEW should be based on a careful and periodic assessment of nutritional status and on timely dietary counseling. When protein and energy intakes are reduced, nutritional supplementation by means of specific oral formulations administered during the hemodialysis session may be the first-step intervention, and represents a valid nutritional approach to PEW prevention and treatment since it is easy, effective and safe. Omega-3 fatty acids and fibers, now included in commercially available preparations for renal patients, could lend relevant added value to macronutrient supplementation. When oral supplementation fails, intradialytic parenteral nutrition can be implemented in selected patients. Copyright © 2016 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

    Markers of better nutritional status including both higher levels of serum albumin (as a measure of visceral proteins) and creatinine (as a measure of the muscle mass) are associated with lower mortality in conventional (thrice weekly) hemodialysis patients. However, data for these associations in twice-weekly hemodialysis patients, in whom less frequent hemodialysis may confound nutritional predictors, are lacking. We identified 1,113 twice-weekly and matched 4,448 thrice-weekly hemodialysis patients from a large national dialysis cohort of incident hemodialysis patients over 5 years (2007-2011). Mortality risk, adjusted for potential confounders, was examined across two-by-two combinations of serum creatinine (creatinine ≥ 6 mg/dL and albumin ≥ 3.5 g/dL as reference, patients with creatinine creatinine mortality associations between twice-weekly and thrice-weekly hemodialysis patients (P-for-interaction = .7667). Surrogate markers of higher visceral protein and muscle mass combined may confer greatest survival in both twice-weekly and thrice-weekly hemodialysis patients.

    Full Text Available Background and Objective: Today more than ever, the importance of health promoting behaviors is considered. Maintaining the function, independence and increasing the quality of life of chronic patients such as hemodialysis patients is influenced by health promoting behaviors. The current study was conducted to determine the effect of education of health promoting behaviors on the quality of life in hemodialysis patients. Materials and Method: In the current quasi-experimental study, 70 hospitalized patients were selected through convenient sampling in hemodialysis wards of two Therapeutic-Educational Centers in Hamadan in 2014. Then, the subjects were randomly allocated into two intervention and control groups of 35 persons. In intervention group, 6 educational sessions were held during the hemodialysis. Quality of life of patients in two groups was measured through Ferrans and Powers Quality of Life Index-dialysis version before and three months after the intervention. Data were analyzed in SPSS 16, and using chi-square test, independent T-test and paired-T test . Results: In intervention group, the mean score of quality of life after intervention was changed from 18.85 ± 5.4 to 20.11 ± 5.46 (p < 0.001 and in control group from 19.41 ± 4.67 to 18.39 ± 4.10 (p = 0.08. After intervention, quality of life of patients in intervention group was increased in health and functioning domain (18.6 ± 5.7 (p < 0.001 and was increased in psychological/spiritual domain to 19.3 ± 7.02 (p=0.041 Conclusion: Education of health-promoting behaviors improved the quality of life of hemodialysis patients. Therefore, according to chronic nature of disease, the education of these behaviors can be effective in improving the quality of life.

    Increased oxidative stress, inflammation, and malnutrition are important risk factors for cardiovascular disease in hemodialysis patients. High dietary intake in soluble fiber can decrease the elevated level of serum c-reactive protein in patients with chronic kidney disease. The aim of this study was to evaluate the effect of supplementation of dietary water-soluble fiber on oxidative and inflammatory status in hemodialysis patients. In a randomized placebo-controlled trial, we examined the effects of supplementation of dietary fiber on oxidative and inflammatory status in hemodialysis patients. 124 hemodialysis patients were randomly selected and given either 10 g/d, 20 g/d of fiber or placebo for 6 weeks. Anthropometric indices and 24 h diet recall intake was assessed. The CRP, albumin, triglyceride, total cholesterol, LDL, HDL were measured before and after of the intervention. The malondialdehyde (MDA), total antioxidant capacity (T-AOC), Cu-Zn superoxidase dismutase (SOD), glutathione peroxidase (GSH-Px) high-sensitivity C-Reactive protein (hs-CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and interleukin-8 (IL-8) were measured. After 6 weeks of intervention, in 10 g and 20 g/d of fiber supplement groups, TC and LDL level and TC:LDL ratio were significantly decreased, T-AOC was significantly increased, MDA level was significantly deceased, TNF-α, IL-6, IL-8 and CRP level were significantly deceased. TG, HDL, SOD and GSH-Px had no change before and after the intervention. Dietary fermentable fiber supplementation improved lipid profile and oxidative status, decreased systemic inflammatory state of hemodialysis patients. Thus, it may decrease the risk of cardiovascular events in these patients.

    Depression is considered as the most common psychological problem in hemodialysis (HD) patients. As there is little evidence regarding the association of depression with serum selenium level as an antioxidant in these patients, the current survey investigates the possible relationship between depression and nutritional status including serum selenium levels. Cross-sectional study. A total of 110 HD patients and 40 healthy controls were enrolled in the study. The patients were in the age range of 18 to 85 years, who had been on hemodialysis for at least 3 months without any acute illness. Beck Depression Inventory was used for assessing the severity of depression. Malnutrition was evaluated through subjective global assessment (SGA) and malnutrition inflammation score (MIS). Serum selenium levels and routine laboratory markers were measured from fasting samples. Sixty-two percent of the patients had some degree of depression based on Beck Depression Inventory score. HD patients were considered to be selenium deficient after comparing the mean value of serum selenium between the patients and controls (P < .001). No significant difference was found in serum selenium levels between depressed HD patients and the rest of patients without depression. The mean level of SGA and MIS in the depressed patients was significantly higher than the rest of patients (P = .03 and P = .04, respectively). Also lower levels of hemoglobin and serum albumin were significantly seen in depressed patients compared with nondepressed ones (P = .004 and P = .04, respectively). Although the HD patients in this study were selenium deficient, no significant association was found between depression and selenium. In addition, depression was more prevalent in malnourished HD patients with higher SGA and MIS scores and lower serum albumin and hemoglobin levels. Copyright © 2015 National Kidney Foundation, Inc.

    Full Text Available Aim: to evaluate the correlation and the concordance between reticulocyte hemoglobin equivalent (RET-He and reticulocyte hemoglobin content (CHr as well as to obtain the cut-off value of RET-He as the target of iron supplementation in chronic kidney disease (CKD patients undergoing hemodialysis. Methods: a cross-sectional study was performed using K3EDTA-anticoagulated peripheral blood samples collected from 106 CKD patients undergoing routine hemodialysis. The samples were then analyzed using both Sysmex XN-2000 and Siemens ADVIA 2120i for RET-He and CHr analysis. Results: a very strong correlation (r=0.91; p<0.0001 and a good concordance were found between RET-He and CHr with mean bias of 0.5 pg. The diagnostic concordance was 96.23%. The cut-off value of RET-He 29.2 pg was obtained from the receiver operating characteristic (ROC curve with CHr as the gold standard. At this cut-off point, the sensitivity and specificity to assess the target of iron supplementation in CKD patients undergoing hemodialysis were 95.5% and 94%, respectively. Conclusion: the study shows a good correlation and concordance between RET-He and CHr in CKD patients undergoing hemodialysis.

    These data indicate that walking impairments in hemodialysis patients are not due exclusively to declines in physical function, but that cognitive-motor interference also plays a significant role. This has significant clinical importance, as therapies designed to improve walking performance and physical function, such as nutritional and exercise interventions, may need to be augmented with cognitive training in order to have maximum benefits.

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

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

    Full Text Available Little is known about actual dietary patterns and their associations with clinical outcomes in hemodialysis patients. We identified dietary patterns in hemodialysis patients in Japan and examined associations between dietary patterns and clinical outcomes.We used data from 3,080 general-population participants in the Hisayama study (year 2007, and data from 1,355 hemodialysis patients in the Japan Dialysis Outcomes and Practice Patterns Study (JDOPPS: years 2005-2007. Food intake was measured using a brief self-administered diet-history questionnaire (BDHQ. To identify food groups with the Hisayama population data, we used principal components analysis with Promax rotation. We adjusted the resulting food groups for total daily energy intake, and then we used those adjusted food-group scores to identify dietary patterns in the JDOPPS patients by cluster analysis (Ward's method. We then used Cox regression to examine the association between dietary patterns and a composite of adverse clinical outcomes: hospitalization due to cardiovascular disease or death due to any cause.We identified three food groups: meat, fish, and vegetables. Using those groups we then identified three dietary patterns: well-balanced, unbalanced, and other. After adjusting for potential confounders, we found an association between an unbalanced diet and important clinical events (hazard ratio 1.90, 95% C.I. 1.19-3.04.Hemodialysis patients whose diet was unbalanced were more likely to have adverse clinical outcomes. Thus hemodialysis patients might benefit not only from portion control, but also from a diet that is well-balanced diet with regard to the food groups identified here as meat, fish, and vegetables.

    Reconsidering when to initiate renal replacement therapy (RRT) in patients with chronic kidney disease (CKD) has been emphasized recently. With evolving modern aged and diabetes-prone populations, conventional markers of uremia are not sufficient for determining the optimal timing for dialysis initiation. This retrospective cohort study examined the association between hyperphosphatemia and uremic patients who need RRT registration. All patients from the department of nephrology in one tertiary medical center in northern Taiwan who had advanced CKD and estimated glomerular filtration rates regression models were used to identify factors associated with hemodialysis initiation decision making. During the study period, 209 of 292 patients with advanced CKD were enrolled in hemodialysis program and 83 patients (controls) were not. Univariable analysis indicated that male sex, current smoking, diabetes mellitus, hypertension, coronary artery disease, high serum creatinine level, and high serum phosphate level were associated with initiation of hemodialysis. Multivariable analysis indicated that those with higher serum phosphate level (odds ratio [OR] = 2.4, 95% confidence interval [CI] = 1.6-3.5, p = 1.4 × 10(-5)) and being in nephrology care for <12 months (OR = 0.4, 95% CI = 0.2-0.8, p = 0.016) tended to be significant markers for hemodialysis initiation. Hyperphosphatemia, in addition to conventional laboratory markers and uremic symptoms, may be a useful marker to determine timing of hemodialysis initiation in patients with advanced CKD.

    The aim of our study was to measure reactive oxygen metabolites (ROMs) in chronic hemodialysis (HD) patients and evaluate the possible association with cardiovascular disease (CVD) and mortality. We measured ROMs in 76 HD patients and correlated with CVD, cardiovascular (CV) events in the follow-up and all-cause and CVD-related mortality. The levels of ROMs presented a median value of 270 (238.2-303.2) CARR U (interquartile range). We created a ROC curve (ROMs levels vs. CVD) and we identified a cut-off point of 273 CARR U. Patients with ROMs levels ≥273 CARR U were significantly older, had higher C-reactive protein levels and lower creatinine concentrations. The prevalence of CVD was higher in patients with ROMs levels ≥273 (87.1%) than in those with ROMs levels <273 CARR U (17.7%; p<0.0001). ROMs levels were significantly higher in patients with CVD (317±63.8) than in those without (242.7±49.1; p<0.0001). At multiple regression analysis, age, creatinine and C-reactive protein were independent factors associated with ROMs. At multiple logistic regression analysis the association between ROMs and CVD was independent (OR: 1.02, 95% CI: 1.00-1.05; p=0.03). Twenty six patients developed cardiovascular (CV) events during the follow-up. Of these, seven were in the group with ROMs levels <273 CARR U and 19 in the group with ROMs levels ≥273 CARR U. The logistic regression analysis showed that both age (OR: 1.06, 95% CI: 1.01-1.12; p=0.013) and ROMs levels (OR: 1.10, 95% CI: 1.00-1.02; p=0.045) were independently associated with CV events in the follow-up. ROMs are independently associated with CVD and predict CV events in chronic HD patients.

    Metabolic acidosis is a common problem in dialysis patients and plays an important role in the pathogenesis of protein-energy malnutrition in these patients. To assess the prevalence of metabolic acidosis in hemodialysis and search their association with nutritional status. A cross-sectional study was performed in hemodialysis patients at a single center. Nutritional status was assessed by anthropometric, biochemical and multifrequency bioelectrical impedance analysis. Metabolic acidosis was defined as serum bicarbonate (BIC) nutritional status, inflammation and bone disease.

Elderly ESRD patients have been found to be more prone to depression than the general population. There are many studies that have addressed the relationship between sleep quality (SQ, depression, and health related quality of life (HRQoL in ESRD patients, but previous studies have not confirmed the association in elderly hemodialysis (HD patients. Therefore, the aim of the present study was to demonstrate this relationship in elderly HD patients.Patients and methods: Sixty-three elderly HD patients (32 females and 31 males aged between 65 and 89 years were included in this cross-sectional study. A modified Post-Sleep Inventory (PSI, the Medical Outcomes Study 36-item short form health survey, and the Beck Depression Inventory (BDI were applied.Results: The prevalence of poor sleepers (those with a PSI total sleep score [PSI-4 score] of 4 or higher was 71% (45/63, and the prevalence of depression was 25% (16/63. Of the 45 poor sleepers, 15 had depression, defined as a BDI score of 17 or higher. Poor sleepers had a significantly higher rate of diabetes mellitus (P = 0.03, significantly higher total BDI scores, and lower Physical Component Scale scores (ie, lower HRQoL than good sleepers. The PSI-4 score correlated negatively with Physical Component Scale (r = −0.500, P < 0.001 and Mental Component Scale

    Poor nutritional status has been associated with worse patient survival in maintenance hemodialysis patients. Anthropometric values are important nutritional measures, incorporating muscle and fat mass. However, the association of changes in anthropometry, including midarm circumference (MAC) and skinfold measurements, with mortality in hemodialysis patients remains unknown. Accordingly, we explored this association in the Hemodialysis (HEMO) Study. Post hoc analysis of cohort data from a clinical trial. 1,846 hemodialysis patients enrolled in the HEMO Study. MAC and skinfold measurements. Longitudinal changes in MAC and skinfolds were jointly modeled using repeated measures and survival modeling. Time-to-event outcomes were all-cause mortality, cardiac death and hospitalization, and infection-related death. Mean MAC was 30.1 cm, and mean baseline sum of subscapular, biceps, and triceps skinfolds was 42.4 mm. During a median follow-up of 2.5 years, there were 845 deaths. During follow-up, MAC and the skinfold measurement declined 0.26 cm and 1.1 mm per year, respectively. Declines in MAC (per cm) and skinfold (per mm) measurements were associated with higher all-cause mortality (HRs of 1.58 [95% CI, 1.29-1.94; P 85 kg. Declines in skinfold thickness were not associated significantly with outcomes except for participants with BMI ≤25 kg/m2. Declines in MAC are associated significantly with all-cause mortality and cardiac outcomes in hemodialysis patients, most notably in those with BMI ≤25 kg/m2.

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

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

    The majority of hemodialyzed patients suffer from sleep disturbances. In the present study the prevalence of sleep apnea syndrome in hemodialyzed patients with end-stage renal disease (ESRD-patients) was investigated by the survey, Epworth Sleepiness Scale (ESS), and polysomnography (PSG). Sixty-one patients: 24 women and 37 men were involved in the study. All subjects participated in the first part of the study consisting of the survey and ESS. The second and third parts consisted of nighttime PSG, performed the night after hemodialysis (17 patients) and between hemodialyses (11 patients). Eleven out of the 61 patients had the symptoms of sleep apnea and heavy daily sleepiness. Eleven subjects were involved in the double PSG study: after and between hemodialyses. Obstructive sleep apnea was found in 7 of those patients during both nights analyzed. Our results confirm the occurrence of sleep disorders in ESRD-patients. Hemodialysis does not change the prevalence of obstructive sleep apnea in chronic renal disease.

    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.

    Full Text Available Hepatitis C virus (HCV infection is commonest blood borne infection amongst hemodialysis patients. Still, there is paucity of data on liver biopsy in these patients. Our center is doing regular liver biopsy in these patients and thus thought of sharing our experience. In this retrospective study, all patients with HCV infection on hemodialysis were subjected to liver biopsy. Serum bilirubin, liver enzyme, HCV-PCR, genotype and viral load measurement were done in all. Biopsy specimen was stained with H and E, Periodic Acid Schiff, Gomori Stain, Masson Trichrome and Perls Stain. International Working Group scoring system of Ishak et al. was used for Grading and Staging. Of the 270 liver biopsies, mean age of patients was 34.05 ΁ 10.28 years and 233 (85.3% were males. Mean duration of hemodialysis was 10.9 ΁ 7.4 months while of known HCV infection was 5.2 ΁ 4.0 months. Genotype 3 was commonest followed by 1. All had normal bilirubin and 64 (23.1% had normal ALT. In 37 (13.3% patients anti-HCV was not detectable. Mean histology grade was 4.03 ΁ 1.65 (1-10 and stage was 0.75 ΁ 0.98 (0-3. Only one patient had cirrhosis on histology. Associated hemosiderosis was seen 10 patients. Only minor complications were observed with no mortality. In conclusion, our study shows that in one-fourth patients with active liver disease, liver enzymes are persistently normal in patients on hemodialysis. Further, carefully performed liver biopsy is reasonably safe procedure though some patients do have non-fatal complications. Liver biopsy helps in assessing disease activity, which otherwise cannot be assessed. Histological grade and stage in these patients is usually mild and cirrhosis is rare. Till such time other non-invasive test is validated, liver biopsy will remain an important test in these patients.

    Nonocclusive mesenteric ischemia (NOMI) is known to occupy about 25% to 60% of intestinal infarction. NOMI has been reported to be responsible for 9% of the deaths in the dialysis population and the postulated causes of NOMI include intradialytic hypotension, atherosclerosis and medications, such as diuretics, digitalis and vasopressors. Clinical manifestations, such as fever, diarrhea and leukocytosis, are nonspecific, which makes early diagnosis of NOMI very difficult. Case: A 66-year-old woman on maintenance hemodialysis for 5 years was admitted with syncope, abdominal pain and chilly sensation. Since 7 days prior to admission, blood pressure on the supine position during hemodialysis had frequently fallen to 80/50 mmHg. Four days later, she complained of progressive abdominal pain. Rebound tenderness and leukocytosis (WBC 13900/mm3) with left shift were noted. Stool examination was positive for occult blood. Abdominal CT scan showed a distended gall bladder with sludge. Under the impression of acalculous cholecystitis, she was operated on. Surgical and pathologic findings of colon colon were compatible with NOMI. Because of recurrent intradialytic hypotension, we started midodrine 2.5 mg just before hemodialysis and increased the dose up to 7.5 mg. After midodrine therapy, blood pressure during dialysis became stable and the symptoms associated with hypotension did not recur. Conclusion: As NOMI may occur within several hours or days after an intradialytic hypotensive episode, abdominal pain should be carefully observed and NOMI should be considered as a differential diagnosis. In addition, we suggest that midodrine be considered to prevent intradialytic hypotensive episodes. PMID:10714097

    Full Text Available Background: Studies suggest that family caregivers of hemodialysis patients experience a high level of burden, which could lead to numerous physical and psychological problems. Despite the need for adequate training and support, these caregivers are mostly neglected, and few studies have been performed in this regard. Aim: to evaluate the effect of educational programs on the home care of hemodialysis patients and burden of their family caregivers. Method: This randomized controlled clinical trial was conducted on 76 caregivers of hemodialysis patients referred to Shahid Hasheminejad Hemodialysis Center of Tehran, Iran in 2015.­ Subjects were divided into two groups of intervention and control (n=38. The intervention group received four training sessions on the home care of hemodialysis patients for two weeks, and the control group received routine care. Data were collected using the Caregiver Burden Inventory (CBI at the beginning and six weeks after the intervention­. Data analysis was performed in SPSS V.21 using Chi-square, Fisher’s exact test, independent and paired T-test, and Mann-Whitney U test. Results: In this study, no significant difference was observed between the two groups in terms of demographic characteristics.

    Conclusion: In chronic hemodialysis patients, preservation of residual renal function is a significant determinant of phosphate control, and the factors associated with phosphate control is different depending on the residual renal function status. In the anuric patients, FGF-23 is most significantly associated with phosphate control; however, glomerular filtration rate and blood urea nitrogen are more important than FGF-23 in the nonanuric HD patients.

    Full Text Available Background. Restless leg syndrome (RLS is one of the prevalent complaints of patients with end stage renal diseases suffering chronic hemodialysis. Although there are some known pharmacological managements for this syndrome, the adverse effect of drugs causes a limitation for using them. In this randomized clinical trial we aimed to find a nonpharmacological way to improve signs of restless leg syndrome and patients’ quality of life. Material and Methods. Twenty-six patients were included in the study and divided into 2 groups of control and exercise. The exercise group used aerobic exercise during their hemodialysis for 16 weeks. The quality of life and severity of restless leg syndrome were assessed at the first week of study and final week. Data were analyzed using SPSS software. Results. The difference of means of RLS signs at the first week of study and final week was in exercise group and in control group. There was not any statistical difference between control group and exercise group in quality of life at the first week of study and final week. Conclusions. We suggest using aerobic exercise for improving signs of restless leg syndrome, but no evidence was found for its efficacy on patient’s quality of life.

    A prospective study was conducted of the incidence and course of acute viral hepatitis in 69 chronic hemodialysis patients. During a mean observation period of 15.4 months, 5.6 cases/100 patients/year of non-A, non-B hepatitis and 1.1 cases/100 patients/year of hepatitis B virus infection occurred. 19 out of 38 patients with serologic evidence of immunity against hepatitis B virus infection developed the antibody to hepatitis B surface antigen after active immunization. All cases of non-A, non-B hepatitis had an asymptomatic course, but there was a tendency to chronicity. The overall impact of non-A, non-B hepatitis in patients on chronic hemodialysis is discussed.

    Comprehensive discussions in scientific literature on the relationship between health professionals teams and renal patients present some particularities regarding professional background and the health care provided. In this paper we have analyzed the kind of care health professionals provide and their interpersonal relationships from the point of view of patients undergoing hemodialysis. Interviews were made using a clinical-qualitative method, consisting of semistructured interviews with seven patients in a hemodialysis unit, who were chosen through an intentional sampling. The data selected were assessed on a thematic content analysis. We have found that patients wish the health care team would listen to their concerns more carefully, which go beyond physical aspects. The clinical care provided has proved to be more focused on biological aspects of patients and on mechanical procedures, showing a considerable degree of carelessness about how human relationships and technical competency differ.

    Hemodialysis ("HD") has been suggested as a risk factor for stent thrombosis. However, platelet function in HD patients after coronary stent implantation remains unclear. The aim of this study was to evaluate platelet function following coronary stent implantation in HD patients. A total of 10 HD and 31 non-HD patients who underwent a first coronary stent implantation were studied. All patients received 100 or 200 mg of asprin and thienopiridine (either ticlopidine 200 mg or clopidogel 75 mg) daily. Platelet function was assessed 2-6 weeks (21 ± 8 days) after stent implantation by: (1) platelet maximal aggregation, using light transmittance aggregometry; (2) platelet aggregation threshold index, which was defined as putative concentration of agonist giving 50% maximum aggregation using whole-blood aggregometry; and (3) platelet activation markers (PAC-1 and CD62p), using whole blood flow cytometry. There were no differences between the two groups in baseline and procedure characteristics, except for a greater prevalence of hypertension and calcification in the HD group. Early stent thrombosis and bleeding did not occur in either group. Although no differences in platelet maximal aggregation or whole-blood aggregation were observed, expression of PAC-1 (39.6 ± 9.1 vs 24.2 ± 13.2%) and CD62p (10.4 ± 5.5 vs 5.4 ± 2.3%) were significantly increased in the HD group compared with the non-HD group. HD patients exhibited enhanced platelet activation after coronary stent implantation, but suppression of platelet aggregation was achieved by the current dual antiplatelet therapy.

    Full Text Available Purpose: Elderly patients who undergo hemodialysis are more fragile than older persons not on dialysis. However, it is not clear if this frailty exists before hemodialysis or if it becomes evident or more acute at the time of beginning a dialysis therapy program. The purpose of this study is to analyze if changes at both the motor and cognitive levels go hand in hand with the beginning of dialysis, and, if this is the case, to identify possible risk factors associated with the functional decline in these patients. Methods: A multicentric prospective pilot observational study was conducted in an ambulatory population with the primary objective to represent the evolution of functional gait capacity in patients before and during hemodialysis treatment, to show gait insecurity during treatment follow-up, if it is present. The secondary objectives are to identify risk factors in the development of gait insecurity, and to measure the prevalence of falls during the follow-up period. Results: The enrolment of patients began in January 2015 and the duration of the data collection will be at least 36 months. In the first 24 months, 19 patients have been included in the study. Preliminary data analysis is not expected before July 2018. Conclusions: The identification of frailty predictors is of major importance in order to identify and target patients at the highest risk of frailty who may be likely to benefit from preventive intervention.

Several animal studies as well as a few case reports and case series have demonstrated that regenerating hepatic tissue can produce more erythropoietin than normal hepatic tissue. The purpose of the study was to examine the difference in hemoglobin and hematocrit levels as well as epoetin dosage in patients on hemodialysis with and without hepatitis C (HCV.Methods: A retrospective chart review was performed. Seventy-six patients were included in the study (19 with HCV and 57 without HCV at a ratio of 1:3. Exclusion criteria were a history of gastrointestinal bleeding or blood transfusion over the previous six months, polycystic kidney disease, and pregnancy. Variables examined included gender, age, duration of hemodialysis, hemoglobin, hematocrit, epoetin dose, aspartate transaminase, and ferritin levels over a three-month period.Results: The patients were divided into two groups. The first consisted of patients with HCV on hemodialysis and the second of patients on hemodialysis without HCV. Mean hemoglobin was 12.6 ± 1.2 g/dL for the HCV-positive group and 11.9 ± 1.1 g/dL for the HCV-negative group. The difference was statistically significant (P = 0.03. Mean hematocrit was higher in the HCV-positive group, but was not significantly different at 39.08% ± 4.06% versus 37.43% ± 3.4% in the HCV-negative group (t-test, P = 0.11. Further, the HCV-positive group required less epoetin, but this was not significantly different from that required in the HCV-negative group at 6258 ± 5208 IU versus 7596 ± 7056 IU, respectively (t-test, P = 0.38.Conclusion: In our study, patients with HCV infection were found to have higher hemoglobin and hematocrit levels and lower epoetin

    Nutritional guidelines recommend eating a variety of foods, yet the renal diet restricts the intake of many foods. Poor appetite, present in 10% to 30% of hemodialysis patients, further narrows the range of foods consumed. We sought to determine the relationship between diet monotony and nutritional intake in patients on chronic hemodialysis. Cross-sectional study. Eight freestanding hemodialysis units in northeast Ohio. Forty-eight randomly selected hemodialysis patients. We used the Block-National Cancer Institute questionnaire to obtain a detailed food frequency and also asked patients to rate their appetite for 10 specific high-protein foods. We adapted the Herfindahl index (a measure of hospital market concentration) to calculate a diet monotony index and then examined the relationship between monotony index and energy and protein intake. When stratified into tertiles by monotony index, patients with the most varied diets had the highest energy (33 kcal/kg/d) and protein (1.35 g/kg/d) intake, whereas patients with the most monotonous diets had the lowest energy (21 kcal/kg/d) and protein (0.83 g/kg/d) intake. A 5-point increase in monotony index was independently associated with a 10 kcal/kg/d decrease in energy intake (P = .004) and a 0.43 g/kg/d decrease in protein intake (P = .006) after adjustment for patient demographic and medical characteristics. Patients with the most monotonous diets reported a good appetite for an average of 3.1 high-protein foods that they were eating less than once per week. Diet monotony strongly correlates with nutritional intake. However, patients with monotonous diets have a good appetite for several high-protein foods that they are not eating. Helping patients to identify and increase the intake of these foods may both enhance diet variety and improve nutritional status. Copyright 2003 by the National Kidney Foundation, Inc.

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

    Full Text Available High prevalence of sleep problems, fatigue and depression are reported in maintenance hemodialysis (MHD patients. To assess fatigue, depression, sleep problems and their co-relates among MHD patients in a tertiary care center in India, we studied 47 patients on MHD for >3 months. Patients demographic, medical and co-morbidity profile were recorded. Pittsburgh Sleep Quality Index (poor sleeper if score >5 and Epworth Sleepiness Scale (EPSS, abnormal daytime sleepiness if score >13 were used to assess sleep abnormalities and quality. Beck Depression Inventory (BDI was used to screen for depression. Depression was classified on BDI scores as mild-moderate (score 11-30 and severe (score >30. Fatigue Severity Scale was used to assess fatigue (score ≥36 indicates fatigue. The correlations of these parameters among themselves and with social and demographic parameters were also analyzed. The mean age of the study population was 37.1 ± 13.1 (range 19-65 years years, with 89.3% being males. The majority (68.1% of the MHD patients was poor sleepers, but only five (10.6% patients had borderline or abnormal daytime sleepiness. Of the patients, 44.7% reported fatigue and (72.3% had depression (mild to moderate in 59.7% and severe in 12.6%. Fatigue scores were found to be significantly associated with lesser frequency of dialysis (P < 0.05. There was higher daytime sleepiness in patients who were working (mean EPSS score 6.2 ± 3.7 than who were unemployed (mean EPSS score 3.9 ± 2.7. Depression was found to be higher in those who were paying for the treatment themselves (mean BDI score 20 ± 11.8 as compared with those who were getting medical expenditure reimbursed (mean BDI score 12.9 ± 8.8. Fatigue positively correlated with that of daytime sleepiness (P = 0.02, poor nighttime sleep (P = 0.02 and depression (P=0.006.

    Full Text Available End-stage renal disease (ESRD patients frequently develop structural cardiac abnormalities, particularly left ventricular hypertrophy (LVH. The mechanisms involved in these processes are not completely understood. In the present study, we evaluated a possible association between parathyroid hormone (PTH levels and left ventricular mass (LVM in patients with ESRD. Stable uremic patients on intermittent hemodialysis treatment were evaluated by standard two-dimensional echocardiography and their sera were analyzed for intact PTH. Forty-one patients (mean age 45 years, range 18 to 61 years, 61% males, who had been on hemodialysis for 3 to 186 months, were evaluated. Patients were stratified into 3 groups according to serum PTH: low levels (280 pg/ml; group III = 21 patients. A positive statistically significant association between LVM index and PTH was identified (r = 0.34; P = 0.03, Pearson's correlation coefficient in the sample as a whole. In subgroup analyses, we did not observe significant associations in the low and intermediate PTH groups; nevertheless, PTH and LVM index were correlated in patients with high PTH levels (r = 0.62; P = 0.003. LVM index was also inversely associated with hemoglobin (r = -0.34; P = 0.03. In multivariate analysis, after adjustment for age, hemoglobin, body mass index, and blood pressure, the only independent predictor of LVM index was PTH level. Therefore, PTH is an independent predictor of LVH in patients undergoing chronic hemodialysis. Secondary hyperparathyroidism may contribute to the elevated cardiovascular morbidity associated with LVH in ESRD.

    Background Although hemoglobin (Hb) levels are affected by a change in the body fluid status, the relationship between Hb levels and mortality while taking interdialytic weight gain (IDWG) at blood sampling into account has not yet been examined in hemodialysis patients. Study design Cohort study. Setting, Participants Data from the Miyazaki Dialysis cohort study, including 1375 prevalent hemodialysis patients (median age (interquartile range), 69 (60–77) years, 42.3% female). Predictor Patients were divided into 5 categories according to baseline Hb levels and two groups based on the median value of IDWG rates at blood sampling at pre-HD on the first dialysis session of the week. Outcomes All-cause and cardiovascular mortalities during a 3-year follow-up. Measurements Hazard ratios were estimated using a Cox model for the relationship between Hb categories and mortality, and adjusted for potential confounders such as age, sex, dialysis duration, erythropoiesis-stimulating agent dosage, Kt/V, comorbid conditions, anti-hypertensive drug use, serum albumin, serum C-reactive protein, serum ferritin, and serum intact parathyroid hormone. Patients with Hb levels of 9–9.9 g/dL were set as our reference category. Results A total of 246 patients (18%) died of all-cause mortality, including 112 cardiovascular deaths. Lower Hb levels (<9.0g/dL) were associated with all-cause mortality (adjusted HRs 2.043 [95% CI, 1.347–3.009]), while Hb levels were not associated with cardiovascular mortality. When patients were divided into two groups using the median value of IDWG rates (high IDWG, ≥5.4% and low IDWG, <5.4%), the correlation between lower Hb levels and all-cause mortality disappeared in high IDWG patients, but was maintained in low IDWG patients (adjusted HRs 3.058 [95% CI,1.575–5.934]). On the other hand, higher Hb levels (≥12g/dL) were associated with cardiovascular mortality in high IDWG patients (adjusted HRs 2.724 [95% CI, 1.010–7.349]), but not in low

    Association between perceived social support and quality of life in hemodialysis patients represents a new area of interest. The aim of this study was to explore the effect of social support on the quality of life of hemodialysis patients. In this study 258 hemodialysis patients were enrolled. Data was collected using a questionnaire which consisted of three parts: a) the Multidimensional Scale of Perceived Social Support (MSPSS) to assess perceived social support, b) the Missoula-VITAS Quality of Life Index (MVQOLI-15) to assess quality of patients' life and c) the socio-demographic, clinical and other variables of patients. To test the existence of association between quality of life and social support the correlation coefficient of Spearman was used. Multiple linear regression was performed to estimate the effect of social support on quality of life (dependent variable), adjusted for potential confounders. The analysis was performed on SPSS v20. Patients felt high support from significant others and family and less from friends (median 6, 6 and 4.5 respectively). Patients evaluated their quality of life in its entirety as moderate in the total and "overall quality of life" score (median 17.2 and 3 respectively). Regarding the association between social support and quality of life, results showed that the more support patients had from their significant others, family and friends, the better quality of life they had. (rho =0,395, rho =0,399 and rho=0,359, respectively). Understanding the relation between social support and quality of life should prompt health professionals to provide beneficial care to hemodialysis patients.

We retrospectively evaluated the medical records of 63 hemodialysis patients who underwent elective (group 1) and 24 who underwent emergency (group 2) abdominal surgeries, and classified them according to the presence/absence of postoperative complications. The clinical, laboratory and procedure-related data were obtained and compared between the groups. Group 2 had significantly higher morbidity and mortality rates than group 1 (58.3 and 16.6 % vs. 33.3 and 16.6 %, respectively, P high BUN levels in the elective surgery patients and hypoproteinemia, hypoalbuminemia, a longer operation and older age in patients undergoing emergency surgery. Perioperative blood transfusion was also associated with a high complication rate in the emergency surgery group.

    Hyponatremia is common in chronic kidney disease and in end stage kidney disease (ESKD) but hypernatremia is infrequent in ESKD. The incidence of hypernatremia is higher in ambulatory peritoneal dialysis (PD) than in hemodialysis (HD) patients. In PD patients it is often a result of excessive ultrafiltration but in HD it is often a result of dialysate composition errors. Dialysate composition errors can inadvertently cause either hyponatremia or hypernatremia. We present two cases of symptomatic hypernatremia which manifested as increased thirst, excessive weight gain and worsening hypertension in HD patients. The hypernatremia was caused by a combination of errors in online conductivity reading and a faulty hand held conductivity meter. Symptoms were relieved in both patients after replacement of the dialysis machine. © 2017 International Society for Hemodialysis.

    Little is known about vascular access conversion and outcomes for patients starting hemodialysis with nonfunctional arteriovenous (AV) access. We assessed mortality risk associated with nonfunctional AV access at hemodialysis initiation, taking subsequent changes in vascular access into account. We studied the 53,092 incident adult hemodialysis patients included in the French REIN registry from 2005 through 2012. AV access placed predialysis was considered nonfunctional when dialysis began with a central venous catheter. Information about vascular access changes was obtained from treatment modality updates. At hemodialysis initiation, AV access was functional for 47% of patients and nonfunctional for 9%; 44% had a catheter alone. After a 3-year follow-up, 63% of patients beginning hemodialysis with a nonfunctional AV access had changed to a functional one, 4% had had a transplant, 19% had died before any vascular access change, and 13% still used a catheter. Cox proportional hazard models with vascular access treated as a time-dependent variable showed an adjusted mortality hazard ratio (95% confidence interval) for patients with nonfunctional AV access who subsequently converted to functional access of 0.95 (95% CI 0.89-1.03) compared with the reference group with functional AV access since first hemodialysis, versus 1.43 (95% CI 1.31-1.55) for those who did not convert. Among patients starting hemodialysis with a nonfunctional AV access, a substantial percentage may never experience successful vascular access conversion. Poor survival seems to be limited to these patients, while those who subsequently convert to functional AV access have similar mortality risk compared to patients with such access since hemodialysis initiation. Every effort should be made to obtain functional AV access in all suitable patients.

Very few studies have examined the effectiveness of pulse alfacalcidol therapy in comparison to daily oral alfacalcidol therapy in suppressing serum parathyroid hormone (PTH levels in hemodialysis patients. The aim of this randomized controlled trial was to replicate the findings of prior studies comparing effectiveness of pulse oral alfacalcidol therapy versus daily oral alfacalcidol therapy in suppressing PTH after 13 weeks of therapy using a Palestinian sample of hemodialysis patients, and to identify demographic and biomedical characteristics of patients that are independently associated with PTH levels.Methods: One hundred and sixty-seven patients completed the study, 88 in the daily group and 79 in the pulse group. The pulse group had more clinically significant reduction in mean PTH level by 75 pg/dL at 13 weeks than the daily group, but this was not statistically significant.Results: The effect of alfacalcidol therapy on metabolism of phosphate and corrected calcium levels was comparable in both groups, and pulse therapy was not associated with increased risk of hypercalcemia and hyperphosphatemia. Serum PTH levels were independently and inversely associated with older age and diabetes.Conclusion: Switching daily alfacalcidol therapy to thrice-weekly alfacalcidol pulse therapy seems safe and convenient, especially for hemodialysis patients with poor compliance

    Home hemodialysis (HHD) facilitates increased treatment frequency, which may improve patient outcomes. However, attrition due to technique failure limits the clinical effectiveness of the modality. Nx2me Connected Health is a telehealth platform that enables ongoing assessment of HHD patients using NxStage equipment, and that may reduce patient burden. We aimed to assess whether use of Nx2me was associated with risk of HHD attrition. We compared risks of all-cause attrition, dialysis cessation (i.e., death or transplant), and technique failure in Nx2me users and matched control patients, using a retrospective cohort study. We also compared the likelihood of HHD training graduation in patients who initiated use of Nx2me during training with the likelihood in matched control patients. Matching factors included date of HHD initiation, NxStage treatment duration at initiation of follow-up, and prescribed treatment frequency. We used stratified Fine-Gray and Cox regression to compare risks, with adjustment for demographic fac
