Full Text Available Abstract Background Studies have shown that insomnia is a common sleep disorder among patients with end-stage renal disease (ESRD. This study aimed to assess the prevalence of insomnia in Saudi patients with ESRD who are on maintenance dialysis. Methods This was an observational cross-sectional study carried out over a period of five months in two hemodialysis centers in Saudi Arabia. To assess the prevalence of insomnia, we used the ICSD-2 definition. We also examined the association between insomnia and other sleep disorders, the underlying causes of renal failure, dialysis duration, dialysis shift, and other demographic data. Results Out of 227 enrolled patients, insomnia was reported by 60.8%. The mean patient age was 55.7 ± 17.2 years; 53.7% were male and 46.3% were female. Insomnia was significantly associated with female gender, afternoon hemodialysis, Restless Legs Syndrome, high risk for obstructive Sleep Apnea Syndrome and excessive daytime sleepiness (P-values: 0.05, 0.01, Conclusion Insomnia is common in dialysis patients and was significantly associated with other sleep disorders. Greater attention needs to be given to the care of dialysis patients with regard to the diagnosis and management of insomnia and associated sleep disorders.

Objective To characterize the influence of dialysis facilities and nephrologists on resource use and patient outcomes in the dialysis population and to illustrate how such information can be used to inform payment system design. Data Sources Medicare claims for all hemodialysis patients for whom Medicare was the primary payer in 2004, combined with the Medicare Enrollment Database and the CMS Medical Evidence Form (CMS Form 2728), which is completed at onset of renal replacement therapy. Study Design Resource use (mainly drugs and laboratory tests) per dialysis session and two clinical outcomes (achieving targets for anemia management and dose of dialysis) were modeled at the patient level with random effects for nephrologist and dialysis facility, controlling for patient characteristics. Results For each measure, both the physician and the facility had significant effects. However, facilities were more influential than physicians, as measured by the standard deviation of the random effects. Conclusions The success of tools such as P4P and provider profiling relies upon the identification of providers most able to enhance efficiency and quality. This paper demonstrates a method for determining the extent to which variation in health care costs and quality of care can be attributed to physicians and institutional providers. Because variation in quality and cost attributable to facilities is consistently larger than that attributable to physicians, if provider profiling or financial incentives are targeted to only one type of provider, the facility appears to be the appropriate locus.

Full Text Available Schizophrenia is closely associated with cardiovascular risk factors which are consequently attributable to the development of chronic kidney disease and end-stage renal disease (ESRD. However, no study has been conducted to examine ESRD-related epidemiology and quality of care before starting dialysis for patients with schizophrenia. By using nationwide health insurance databases, we identified 54,361 ESRD-free patients with schizophrenia and their age-/gender-matched subjects without schizophrenia for this retrospective cohort study (the schizophrenia cohort. We also identified a cohort of 1,244 adult dialysis patients with and without schizophrenia (1:3 to compare quality of renal care before dialysis and outcomes (the dialysis cohort. Cox proportional hazard models were used to estimate the hazard ratio (HR for dialysis and death. Odds ratio (OR derived from logistic regression models were used to delineate quality of pre-dialysis renal care. Compared to general population, patients with schizophrenia were less likely to develop ESRD (HR = 0.6; 95% CI 0.4-0.8, but had a higher risk for death (HR = 1.2; 95% CI, 1.1-1.3. Patients with schizophrenia at the pre-ESRD stage received suboptimal pre-dialysis renal care; for example, they were less likely to visit nephrologists (OR = 0.6; 95% CI, 0.4-0.8 and received fewer erythropoietin prescriptions (OR = 0.7; 95% CI, 0.6-0.9. But they had a higher risk of hospitalization in the first year after starting dialysis (OR = 1.4; 95% CI, 1.0-1.8, P < .05. Patients with schizophrenia undertaking dialysis had higher risk for mortality than the general ESRD patients. A closer collaboration between psychiatrists and nephrologists or internists to minimize the gaps in quality of general care is recommended.

Full Text Available Thyroid hormone level may be altered in chronic renal failure patients. Low levels of thyroxine protect the body from excess protein loss by minimizing catabolism. Hyperthyroidism is rarely encountered in end-stage dialysis dependent patients. Less than 10 well-documented cases of Graves′ disease (GD are reported in literature so far. We report a case of GD in a patient on dialysis.

The aim of the study was to explore renal nurses' experiences, strategies and challenges with regard to the patient education process in peritoneal dialysis. Patient education in peritoneal dialysis is essential to developing a successful home-based peritoneal dialysis program. In this area research is scarce and there is a particular lack of focus on the perspective of the renal nurse. Qualitative design formed by thematic qualitative text analysis. Five group interviews (n = 20) were used to explore the challenges peritoneal dialysis nurses face and the training strategies they use. The interviews were analyzed with thematic qualitative content analysis using deductive and inductive subcategory application. The findings revealed the education barriers perceived by nurses that patients may face. They also showed that using assessment tools is important in peritoneal dialysis patient education, as is developing strategies to promote patient self-management. There is a need for a deeper understanding of affective learning objectives, and existing teaching activities and materials should be revised to incorporate the patient's perspective. Patients usually begin having questions about peritoneal dialysis when they return home and are described as feeling overwhelmed. Adapting existing conditions is considered a major challenge for patients and nurses. The results provided useful insights into the best approaches to educating peritoneal dialysis patients and served to raise awareness of challenges experienced by renal nurses. Findings underline the need for nosogogy - an approach of teaching adults (andragogy) with a chronic disease. Flexibility and cooperation are competencies that renal nurses must possess. Still psychomotor skills dominate peritoneal dialysis patient training, there is a need of both a deeper understanding of affective learning objectives and the accurate use of (self-)assessment tools, particularly for health literacy. © 2016 John Wiley & Sons

In total joint arthroplasty (TJA) literature, there is a paucity of large cohort studies comparing chronic kidney disease (CKD) and end-stage renal disease (ESRD) vs non-CKD/ESRD patients. Thus, the purposes of this study were (1) to identify inhospital complications and mortality in CKD/ESRD and non-CKD/ESRD patients and (2) compare inhospital complications and mortality between dialysis and renal transplantation patients undergoing TJA. We queried the Nationwide Inpatient Sample database for patients with and without diagnosis of CKD/ESRD and those with a renal transplant or on dialysis undergoing primary or revision total knee or hip arthroplasty from 2007 to 2011. Patient comorbidities were identified using the Elixhauser comorbidity index. International Classification of Diseases, Ninth Revision, codes were used to identify postoperative surgical site infections (SSIs), wound complications, deep vein thrombosis, and transfusions. Chronic kidney disease/ESRD was associated with greater risk of SSIs (odds ratio [OR], 1.4; Prenal transplant patients. Chronic kidney disease/ESRD patients had a greater risk of SSIs and wound complications compared to those without renal disease, and the risk of these complications was even greater in CKD/ESRD patients receiving dialysis. These findings emphasize the importance of counseling CKD patients about higher potential complications after TJA, and dialysis patients may be encouraged to undergo renal transplantation before TJA.

Recently, ultrasound-guided percutaneous renal biopsy has been used in the diagnosis of renal diseases. Development of an arteriovenous fistula (AVF), which is one of the post-biopsy complications, is not frequently encountered. AVFs are usually asymptomatic; however, they may lead to serious outcomes. We report a 21-year-old patient, who had been on dialysis for 5 years. Due to high blood pressure (230/160 mmHg) and a thrill in the lumbar area detected on physical examination, Doppler examination was performed and a renal AVF was detected. Because the patient had a history of renal biopsy 5 years previously, the fistula was thought to be secondary to the biopsy. After embolization of the AVF, renal functions improved enough to terminate dialysis treatment.

Interventional catheterization procedures may be needed for patients with severe renal failure who are dependent on dialysis. To avoid the risk of fluid overload and electrolyte derangement during complex procedures in this oliguric/anuric patient population, we performed intra-procedural dialysis, either continuous renal replacement therapy (CRRT) or continous cycling peritoneal dialysis (CCPD). We performed a retrospective review of a cohort of pediatric patients, ages 0-18 years, with dialysis-dependent renal failure who received CRRT or CCPD during catheterization procedures from January 2013 to March 2016. Eight patients underwent a total of nine interventional catheterization procedures while receiving intra-procedural dialysis. Median age was 4.5 years (range 8 months to 17 years) and weight, 11.6 kg (11.2-62.6 kg). Six patients had end-stage renal disease (ESRD) and two patients had acute kidney injury (AKI), one due to hepatorenal syndrome and one due to multifactorial causes associated with congenital heart disease. The most common reason for catheterization was occlusive venous thrombosis requiring recanalization. CRRT was used during five cases and CCPD during four cases. Median procedure time was 337 min (95-651 min) and median contrast dose 4.2 mL kg -1 (1.2-8.2 mL kg -1 ). Euvolemia was maintained based on pre- and post-catheterizations weights, and no significant electrolyte abnormalities occurred based on lab monitoring during and post-procedure. Intra-procedural dialysis using CRRT or CCPD enables even small pediatric patients with severe renal failure to undergo long and complex interventional catheterizations by reducing the risk of fluid overload and electrolyte abnormalities. Collaboration between nephrology, cardiology, and dialysis teams is necessary for successful management of this challenging patient population. © 2017 Wiley Periodicals, Inc.

Given the public health challenge and burden of chronic kidney disease, the Italian Society of Nephrology (SIN) promoted a census of the renal and dialysis units to analyse structural and human resources, organizational aspects, activities and workload referring to the year 2014. An online questionnaire, including 64 items exploring structural and human resources, organization aspects, activities and epidemiological data referred to 2014, was sent to chiefs of any renal or dialysis unit. 615 renal units were identified. From these 615 units, 332 were public renal centres (of which 318 centres answered to the census) and 283 were private dialysis centres (of which 113 centres answered to the census). The results show 6 public renal units pmp. Renal biopsies were 4624 (81 pmp). The nephrology beds are about 41 pmp. There are 7.304 nurses working in HD wards, 1.692 in the nephrology wards and only 613 for outpatients clinics. The benchmark data derived from this census show interesting comparisons between centres, regions and groups of regions. These data realised the clinical management of renal disease in Italy.

Examination of nephrology practice variations in living donor renal grafts to determine their influence on organ supply, quality, and cost of chronic renal failure therapy. Saskatchewan chronic dialysis, cadaveric, and living donor renal grafts in 1983-1994 inclusive. Saskatchewan has three dialysis (I, II, III) and one transplant clinic. In the period the renal graft incidences/million population by these dialysis clinics by organ source were; Cadaveric: 23.1, 23.2, 21.1 (p = ns). Living: 5.4, 21.7, 8.3 (I or III vs II p actuarial patient survival is 92% and B 44%. Series A ten-year actuarial graft survival (including regrafts) is 77% and B 39%. Rehabilitation rate in patients with functioning grafts is 88.5%. Province-wide extension of the Clinic II living-donor graft rate in 1983-1994 would have produced 160 more renal grafts or 59% of those receiving chronic dialysis in 1994. The annual maintenance for a graft with the initial grafting cost taken over five years was $10,825 and the dialysis cost $40,100. (1) nephrology practice variations caused a 2.5-4.0-fold difference in living donor renal graft rates, indicating patient education by the attending nephrologist influences the living donor transplantation rate, (2) with such education the combined living donor and the cadaveric organ supply virtually meets graft demand, (3) living donor renal grafts yield a better quantity and quality of life and better cost control than dialysis with their annual cost being one-quarter that for dialysis.

Full Text Available Cystinosis is an autosomal recessive, lysosomal storage disease characterised by the accumulation of the amino acid cystine in different organs and tissues. It is a multisystemic disease that can present with renal and extra-renal manifestations. In this report, we present the first case of transplanted nephropathic cystinosis in a Tunisian child. A 4-year-old Tunisian boy born to nonconsanguineous parents, was treated in our medical services in 1990 for cystinosis. Since the age of five months, he developed symptoms of severe weight loss, vomiting, dehydration, and polyuria. He manifested the Toni Debré Fanconi syndrome. Slit lamp examination of the anterior segment of both eyes revealed fine, shiny crystal-like deposits diffusely distributed in the corneal epithelium and the stroma. Our patient had renal failure. At the age of seven, he reached terminal chronic renal failure and was treated with peritoneal dialysis. Hemodialysis was started at the age of nine years. At the age of 13 years, he received a renal transplantation and was started on cysteamine 1999, five months after the renal transplantation. Currently, the patient is 28-year-old. The graft has survived 15 years after the transplantation. Renal functions were stable with a serum creatinine of 123 μmol/L at last follow-up.

Background: Chronic kidney disease and the methods of its treatment play an important part in shaping the QoL of patients receiving dialysis. As a result, kidney failure causes many limitations in patients’ physical, mental, and social activities. Methods: The instrument to measure the QoL was the authors’ own questionnaire made on the basis of Kidney Disease and Quality of Life Short Form version 1.2 (KDQOL – SF 1.2 and their selection of areas influencing the perceived QoL of chronically ill patients. Results: The research showed that patients receiving peritoneal dialysis assessed their QoL in its different dimensions as much higher than patients receiving hemodialysis. The parameter having the biggest negative impact on the QoL of patients receiving hemodialysis was an impeded possibility to continue work or studies and a change of life plans. The will to live was more highly assessed by patients receiving peritoneal dialysis as compared to patients receiving hemodialysis. Conclusion: In order to improve the functioning of hemodialysis patients in a manner most similar to healthy persons, the renal replacement therapy should consider patients’ individual needs and expectations, ie, guarantee flexible hours of work or study and of receiving dialysis. In addition, patients treated with hemodialysis should receive

Chronic renal failure is a type of clinical syndrome originating from chronic renal diseases. The aim of the study was to investigate the effect of astrogaloside on the inflammation and immunity of renal failure patients receiving maintenance dialysis. We randomly selected 92 renal failure patients receiving maintenance dialysis who were admitted to hospital for treatment between May, 2015 and April, 2016. Patients were randomly divided into the control (n=46) and observation (n=46) groups. Patients in the control group received the regular dialysis plus the basic treatment in Western medicine, while in the observation group, patients additionally received astrogaloside via intravenous injection as treatment. We compared the clinical efficacy of patients between the two groups, residual renal function (RRF), changes in urine volume, variations in inflammatory indicators [C-reaction protein (CRP), interleukin-6 (IL-6), IL-17, and tumor necrosis factor-α (TNF-α)] before and after treatment, and the levels of the thymus-dependent lymphocyte (T cells) subgroup (CD3 + , CD4 + , CD8 + and CD4 + /CD8 + ) in the immune system of patients after treatment. In the observation group, the total effective rate was significantly higher than that in the control group (Prenal failure patients receiving the maintenance dialysis, ameliorate the inflammatory responses, and enhance the immune function, thereby increasing the disease resistance of patients and improving the clinical symptoms.

Full Text Available Today the problem of better life quality of patients with end stage renal disease and after renal transplantation and their sexual adaptation is considered to be more impotent. The clinical part of the investigation is the obser- vation of 205 patients – men with terminal stage renal disease. Erectile dysfunction is represented in 91,4% (64 of patients getting haemodialysis, 92,3% (24 of patients getting peritoneal dialysis, 61,5% (67 of patients after renal transplantation. According to International Index of Erectile Function the mean score of erectile function is 16,7 ± 5,2 in haemodialysis patients, 19,46 ± 3,6 in peritoneal dialysis patients, 21,9 ± 5,6 in patients after renal transplantation. The analysis revealed great prevalence of erectile dysfunction and interest in improvement among the patients with end stage renal disease and after renal transplantation.

Advanced chronic kidney disease is associated with elevated risk for cognitive impairment. However, it is not known whether and how cognitive impairment is associated with planning and preparation for end-stage renal disease. Retrospective observational study. 630 adults participating in the CRIC (Chronic Renal Insufficiency Cohort) Study who had cognitive assessments in late-stage CKD, defined as estimated glome-rular filtration rate ≤ 20mL/min/1.73m 2 , and subsequently initiated maintenance dialysis therapy. Predialysis cognitive impairment, defined as a score on the Modified Mini-Mental State Examination lower than previously derived age-based threshold scores. Covariates included age, race/ethnicity, educational attainment, comorbid conditions, and health literacy. Peritoneal dialysis (PD) as first dialysis modality, preemptive permanent access placement, venous catheter avoidance at dialysis therapy initiation, and preemptive wait-listing for a kidney transplant. Multivariable-adjusted logistic regression. Predialysis cognitive impairment was present in 117 (19%) participants. PD was the first dialysis modality among 16% of participants (n=100), 75% had preemptive access placed (n=473), 45% avoided using a venous catheter at dialysis therapy initiation (n=279), and 20% were preemptively wait-listed (n=126). Predialysis cognitive impairment was independently associated with 78% lower odds of PD as the first dialysis modality (adjusted OR [aOR], 0.22; 95% CI, 0.06-0.74; P=0.02) and 42% lower odds of venous catheter avoidance at dialysis therapy initiation (aOR, 0.58; 95% CI, 0.34-0.98; P=0.04). Predialysis cognitive impairment was not independently associated with preemptive permanent access placement or wait-listing. Potential unmeasured confounders; single measure of cognitive function. Predialysis cognitive impairment is associated with a lower likelihood of PD as a first dialysis modality and of venous catheter avoidance at dialysis therapy

Full Text Available To estimate the costs and effectiveness measured in quality-adjusted life years (QALY of kidney transplantation compared with dialysis in adults suffering from end-stage renal disease from the perspective of the Colombian healthcare system, we designed a Markov model with monthly cycles over a five-year time horizon and eight transitional states, including death as an absorbing state. Transition probabilities were obtained from international registries, costs from different local sources [case studies, official tariffs (ISS 2001 + 35% for procedures and SISMED for medications]. Data were validated by an expert panel and we performed univariate, multivariate and probabilistic sensitivity analyses. Effectiveness indicators were months of life gained, months of dialysis averted and deaths prevented. The annual discount rate was 3% and the cost-utility threshold (willingness to pay was three times gross domestic product (GDP = USD 20,000 per QALY. The costs were adopted in US dollars (USD using the 2012 average exchange rate (1 USD = COP$ 1798. The discounted average total cost for five years was USD 76,718 for transplantation and USD 76,891 for dialysis, with utilities 2.98 and 2.10 QALY, respectively. Additionally, renal transplantation represented 6.9 months gained, 35 months in dialysis averted per patient and one death averted for each of the five patients transplanted in five years. We conclude that renal transplantation improves the overall survival rates and quality of life and is a cost-saving alternative compared with dialysis.

A retrospective review of 246 patients with established acute renal failure (ARF) needing dialysis from 1990-1994 is reported from Hospital Sultanah Aminah, Johor Bahru. Peritoneal dialysis was more commonly used than haemodialysis or haemofiltration. Patients on mechanical ventilation in Intensive Care Unit (ICU) who were hypercatabolic and fluid overloaded were treated with haemofiltration. Males outnumbered females by a ratio of 1.5:1. The majority were Malays (61.4%). Most patients were from the district of Johor Bahru, but 41.5% were from other districts in the Johor state. The mean age was 47.1 years (SD 18.2). The ARF was caused by acute tubular necrosis in 55.3%, post-renal obstruction in 22.8%, nephrotoxins in 5.7% and other causes in 16.2%. The proportions of patients referred from the medical, surgical and obstetric and gynaecology units were 50.8%, 45.5% and 3.7% respectively. The mortality rate was 48%. Patients with established ARF should be dialysed early as they tolerate uraemia poorly. Prevention is by prompt treatment of patients with sepsis, avoidance of hypovolaemia and nephrotoxic drugs.

2017-09-01

The Lancashire Teaching Hospitals NHS Trust in the UK has been providing renal care through video-as-a-service (VAAS) to patients since 2013, with support from the North West NHS Shared Infrastructure Service, a collaborative team that supports information and communication technology use in the UK National Health Service. Renal telemedicine offered remotely to patients on home dialysis supports renal care through the provision of a live high-quality video link directly to unsupported patients undergoing haemodialysis at home. Home haemodialysis is known to provide benefits to patients, particularly in making them more independent. The use of a telemedicine video-link in Lancashire and South Cumbria, UK, further reduces patient dependence on the professional team. The purpose of this paper is to present the perspectives of the renal care team members using the renal telemedicine service to understand the perceived benefits and issues with the service. Ten semi-structured interviews with members of the renal care team (two renal specialists, one matron, two renal nurses, one business manager, one renal technical services manager, two IT technicians and one hardware maintenance technician) were conducted. Thematic analysis was undertaken to analyse the qualitative data. A range of incremental benefits to the renal team members were reported, including more efficient use of staff time, reduced travel, peace of mind and a strong sense of job satisfaction. Healthcare staff believed that remote renal care through video was useful, encouraged concordance and could nurture confidence in patients. Key technological issues and adjustments which would improve the renal telemedicine service were also identified. The impact of renal telemedicine was positive on the renal team members. The use of telemedicine has been demonstrated to make home dialysis delivery more efficient and safe. The learning from staff feedback could inform development of services elsewhere. © 2017

Racial/ethnic, gender, and age disparities in access to renal transplantation among end-stage renal disease (ESRD) patients have been well documented, but few studies have explored health care staff attitudes towards these inequalities. Staff perceptions can influence patient care and outcomes, and identifying staff perceptions on disparities could aid in the development of potential interventions to address these health inequities. The objective of this study was to investigate dialysis staff (n = 509), primarily social workers and nurse managers, perceptions of renal transplant disparities in the Southeastern United States. This is a mixed methods study that uses both deductive and inductive qualitative analysis of a dialysis staff survey conducted in 2012 using three open-ended questions that asked staff to discuss their perceptions of factors that may contribute to transplant disparities among African American, female, and elderly patients. Study results suggested that the majority of staff (n = 255, 28%) perceived patients' low socioeconomic status as the primary theme related to why renal transplant disparities exist between African Americans and non-Hispanic whites. Staff cited patient perception of old age as a primary contributor (n = 188, 23%) to the disparity between young and elderly patients. The dialysis staff responses on gender transplant disparities suggested that staff were unaware of differences due to limited experience and observation (n = 76, 14.7%) of gender disparities. These findings suggest that dialysis facilities should educate staff on existing renal transplantation disparities, particularly gender disparities, and collaboratively work with transplant facilities to develop strategies to actively address modifiable patient barriers for transplant.

Full Text Available High-cut-off hemodialysis (HCO-HD can effectively reduce high concentrations of circulating serum free light chains (sFLC in patients with dialysis-dependent acute kidney injury (AKI due to multiple myeloma (MM. Therefore, the aim of this study was to analyze renal recovery in a retrospective single-center cohort of dialysis-dependent MM patients treated with either conventional HD (conv. HD or HCO-HD.The final cohort consisted of 59 patients treated with HCO-HD (n = 42 or conv. HD (n = 17. A sustained sFLC response was detected in a significantly higher proportion of HCO-HD patients (83.3% compared with conv. HD patients (29.4%; p = 0.007. The median duration of sFLC required to reach values <1000 mg/l was 14.5 days in the HCO-HD group and 36 days in the conv. HD group. The corresponding rates of renal recovery were 64.3% and 29.4%, respectively (chi-squared test, p = 0.014. Multivariate regression and decision tree analysis (recursive partitioning revealed HCO-HD (adjusted odds ratio [OR] 6.1 [95% confidence interval (CI 1.5-24.5], p = 0.011 and low initial uric acid values (adjusted OR 1.3 [95%CI 1.0-1.7], p = 0.045 as independent and paramount variables associated with a favorable renal outcome.In summary, the results from this retrospective case-control study suggest in addition to novel agent-based chemotherapy a benefit of HCO-HD in sFLC removal and renal outcome in dialysis-dependent AKI secondary to MM. This finding was especially pertinent in patients with low initial uric acid values, resulting in a promising renal recovery rate of 71.9%. Further prospective studies are warranted.

Proteinuria is an established risk factor for progression of renal disease, including diabetic nephropathy. The predictive power of proteinuria, especially nephrotic range proteinuria, for progressive renal deterioration has been well demonstrated in diabetic patients with normal to relatively preserved renal function. However, little is known about the relationship between severity of proteinuria and renal outcome in pre-dialysis diabetic patients with severely impaired renal function. 125 incident dialysis patients with type 2 diabetes were identified. This study was aimed at retrospectively evaluating the impact of nephrotic range proteinuria (urinary protein-creatinine ratio above 3.5 g/gCr) on renal function decline during the 3 months just prior to dialysis initiation. In total, 103 patients (82.4 %) had nephrotic range proteinuria. The median rate of decline in estimated glomerular filtration rate (eGFR) in this study population was 0.98 (interquartile range 0.51-1.46) ml/min/1.73 m(2) per month. Compared to patients without nephrotic range proteinuria, patients with nephrotic range proteinuria showed significantly faster renal function decline (0.46 [0.24-1.25] versus 1.07 [0.64-1.54] ml/min/1.73 m(2) per month; p = 0.007). After adjusting for gender, age, systolic blood pressure, serum albumin, calcium-phosphorus product, hemoglobin A1c, and use of an angiotensin-converting enzyme inhibitor or an angiotensin II receptor blocker, patients with nephrotic range proteinuria showed a 3.89-fold (95 % CI 1.08-14.5) increased risk for rapid renal function decline defined as a decline in eGFR ≥0.5 ml/min/1.73 m(2) per month. Nephrotic range proteinuria is the predominant renal risk factor in type 2 diabetic patients with severely impaired renal function receiving pre-dialysis care.

Full Text Available Background: It has been shown that in-center hemodialysis (HD nurses prefer in-center HD for patients with certain characteristics; however it is not known if their opinions can be changed. Objective: To determine if an education initiative modified the perceptions of in-center HD nurses towards home dialysis. Design: Cross-sectional survey of in-center HD nurses before and after a three hour continuing nursing education (CNE initiative. Content of the CNE initiative included a didactic review of benefits of home dialysis, common misconceptions about patient eligibility, cost comparisons of different modalities and a home dialysis patient testimonial video. Setting: All in-center HD nurses (including those working in satellite dialysis units affiliated with a single academic institution Measurements: Survey themes included perceived barriers to home dialysis, preferred modality (home versus in-center HD, ideal modality distribution in the local program, awareness of home dialysis and patient education about home modalities. Methods: Paired comparisons of responses before and after the CNE initiative. Results: Of the 115 in-center HD nurses, 100 registered for the CNE initiative and 89 completed pre and post surveys (89% response rate. At baseline, in-center HD nurses perceived that impaired cognition, poor motor strength and poor visual acuity were barriers to peritoneal dialysis and home HD. In-center HD was preferred for availability of multidisciplinary care and medical personnel in case of catastrophic events. After the initiative, perceptions were more in favor of home dialysis for all patient characteristics, and most patient/system factors. Home dialysis was perceived to be underutilized both at baseline and after the initiative. Finally, in-center HD nurses were more aware of home dialysis, felt better informed about its benefits and were more comfortable teaching in-center HD patients about home modalities after the CNE session

The aims of this study were to identify the incidence of renal failure requiring dialysis and to investigate the long-term outcome after renal failure in liver transplantation (LT) patients. The primary database used was the Taiwan National Health Insurance Research Database. Subjects with LT from 1997 to 2009 were included. Patients were grouped into the dialysis cohort if they once received hemodialysis owing to any pattern of renal failure during peri-transplantation periods or after LT. Otherwise, they were categorized into the nondialysis cohort. We conducted a retrospective observational study on the correlation of renal failure requiring dialysis and its effect on LT recipients. The analysis included data of 1,771 LT recipients with a mean follow-up time of 3.8 ± 2.9 years. The mean age was 43.2 ± 19.3 years, and 69.4% were male. Overall patient survival was 86.2% at 1 year, 82.2% at 3 years, and 80.5% at 5 years. Renal failure requiring dialysis had developed in the 323 patients (18.2%). Among them, 26 individuals (1.5%) had progressed to end-stage renal disease without renal recovery after perioperative hemodialysis. Individuals who developed renal failure requiring dialysis had a higher mortality compared with LT recipients never requiring dialysis (hazard ratio, 8.75; 95% confidence interval, 7.0-10.9). Renal failure requiring dialysis development after LT is common and carries high mortality in Chinese liver allograft recipients. Recognizing risk factors permits the timely institution of proper treatment, which is the key to reducing untoward outcomes. Copyright © 2016 Elsevier Inc. All rights reserved.

2005-01-01

Full Text Available Introduction. In the last few years, an increasing number of patients suffering from terminal renal disease of various leading causes was treated with renal replacement therapy. Peritonaeal dialysis involves an exchange of water and solutes between blood in the peritonaeal capillaries and dialysate in the peritonaeal cavum throughout the peritonaeum. Effective dialysis treatment should provide good quality of life, decrease the number of physical complaints, and bring the incidence of morbidity and mortality closer to the incidence of morbidity and mortality in the healthy population. Aim. The aim of this study was the evaluation of peritonaeal transport characteristics and dialysis effectiveness in 58 patients affected by terminal renal disease who underwent peritonaeal dialysis treatment during August 2003 at the Clinic of Nephrology of the Clinical Centre of Serbia. Method. We examined 30 male and 28 female patients, with an average age of 52 years (range 26 to 78 years. The average duration of peritoneal dialysis treatment was 20 months (ranging from 2 to 66 months, and the end-stage renal failure was caused by different leading disease in our patients. We applied different dialysis modalities: continuous ambulatory peritonaeal dialysis (CAPD with three to five 2- or 3-litre exchanges daily, cyclic peritonaeal dialysis (CCPD, intermittent peritonaeal dialysis (IPD, or automatic peritonaeal dialysis (APD, according to the transport characteristics of the peritonaeal membrane, the residual renal function (RRF, and the clinical status of the patients, in order to perform adequate depuration as suggested by the new international criteria. A peritonaeal equilibrium test (PET was performed according to the new international advice; urea and creatinine clearances (Kt/V and Ccr as well as RRF were calculated using the internationally suggested formulas. Results. Most of our patients received effective dialysis treatment, thanks to the modulation of

Patients with end-stage renal disease require renal replacement therapy with either dialysis or kidney transplantation. Survival and quality of life (QoL) after transplantation are superior to chronic dialysis. Early living donor kidney transplantation is best for patient and graft survival. Preemptive living-related kidney transplantation therefore is the best medical treatment option for these patients. Patients with end-stage renal disease suffer from multiple physical and psychological complaints. The prevalence of depressive disorders is 20-25% in this population. Studies on QoL in children after kidney transplantation show a reduced physical QoL, but an overall good psychological QoL. Alarming results of numerous studies are the high non-adherence rates in adolescents. Especially exercise interventions during dialysis and after kidney transplantation show promising results. Whether QoL of patients will improve with new approaches to immunosuppressive therapy remains to be evaluated in future studies.

The incidence of chronic renal failure increase with the age. The selection of patient to dialysis has been increasing in spite of the high comorbidity. Moreover, in our clinical practice the aged patient is not contraindicated to dialysis. However, in the nephrology clinical practice not all the patients start the treatment with dialysis. OBJECTIVE The aim of our study has been to compare the characteristics of the patients who had not been dialyzed between the periods 1992-1995 and 2000-2003 to analyze the trend of the nephrology clinical practice. Comparative study of the characteristics and the evolution of patients with chronic renal failure in stage V, (renal failure) not incorporated to dialysis in one hospital during four years between the periods the 1992-1995 ( period A) and 2000-2003 (period B). Start dialysis (period A versus period B): 116 patients, age 59.9+15.5 years vs. 229 patients, age 64.0+15.8 years (pcreatinina 7.4+2.4 mg/dl vs. 5.3+1.2 mg/dl (p<0.001), MDRD estimate glomerular filtration 6.9+2.4 mg/dl ml/min/1.73 m2 vs. 10.0+2.3 ml/min/1.73 m2 (p<0.001). Primary renal disease: unknown etiology 31.5 % vs. 24.3 %, nephroangiosclerosis 23.6 % vs. 32.4 %, diabetes 28.9 % vs. 21.6 %. Functional status: dependent patients 34.2 % vs 83.8 % (p<0.001). The principal reason for non-dialysis were: personal decision: 26.3 % vs. 35.1 %, dementia 15.8 % vs. 29.7 %, brief life expectancy because of serious co-existing diseases 13.1 % vs. 21.7 % and serious chronic illness with inability for themselves care 44.7 % vs. 13.1 %. Comorbid conditions: 2.3+1.0 vs. 3.0+1.5 (p<0.05). Survival: 55+168 days vs. 168+236 days (p<0.001). Most of the patients that don't begin dialysis are elderly together with a poor functional capacity and with more autonomy in their decisions. The identification of patients with renal failure (stage V) was detected early in the last period than in the following one. The conservative management of non-dialyzed uremic patients is a

Infective endocarditis is one of the most common infections among intravenous drug addicts. Its complications can affect many systems, and these can include acute renal failure. There is a scarcity of cases in the literature related to acute renal failure secondary to infective endocarditis treated with peritoneal dialysis. In this paper, the case of a 48-year-old Saudi male is reported, who presented with features suggestive of infective endocarditis and who developed acute kidney injury that was treated successfully with high tidal volume automated peritoneal dialysis. To our knowledge, this is the second report of such an association in the literature. A 48-year-old Saudi gentleman diagnosed to have a glucose-6-phosphate dehydrogenase deficiency and hepatitis C infection for the last 9 years, presented to the emergency department with a history of fever of 2 days' duration. On examination: his temperature = 41 °C, there was clubbing of the fingers bilaterally and a pansystolic murmur in the left parasternal area. The results of the blood cultures and echocardiogram were supportive of the diagnosis of infective endocarditis, and the patient subsequently developed acute kidney injury, and his creatinine reached 5.2 mg/dl, a level for which dialysis is essential for the patient to survive. High tidal volume automated peritoneal dialysis is highly effective as a renal replacement therapy in acute renal failure secondary to infective endocarditis if no contraindication is present.

Encapsulating peritoneal sclerosis is a rare complication of long-term peritoneal dialysis ranging from moderate inflammation of peritoneal structures to severe sclerosing peritonitis and encapsulating peritoneal sclerosis. Complicated it, ileus may occur during or after peritoneal dialysis treatment or after kidney transplant. We sought to evaluate 3 posttransplant encapsulating peritoneal sclerosis through clinical presentation, radiologic findings, and outcomes. We analyzed 3 renal transplant patients with symptoms of encapsulating peritoneal sclerosis admitted posttransplant to our hospital with ileus between 2012 and 2013. Conservative treatment was applied to the patients whenever necessary to avoid surgery. One patient improved with medical therapy. Surgical treatment was delayed and we decided it as a last resort, in 2 cases with no response to conservative treatment for a long time. Finally, patients with peritoneal dialysis history should be searched carefully before renal transplant for intermittent bowel obstruction story.

The burgeoning population of patients requiring renal replacement therapy contributes a disproportionate strain on National Health Service resources. Although renal transplantation is the preferred treatment modality for patients with established renal failure, achieving both clinical and financial advantages, limitations to organ donation and clinical comorbidities will leave a significant proportion of patients with established renal failure requiring expensive dialysis therapy in the form of either hemodialysis or peritoneal dialysis. An understanding of dialysis economics is essential for both healthcare providers and clinical leaders to establish clinically efficient and cost-effective treatment modalities that maximize service provision. In light of changes to the provision of healthcare funds in the form of "Payment by Results," it is imperative for UK renal units to adopt clinically effective and financially accountable dialysis programs. This article explores the role of dialysis economics and implications for UK renal replacement therapy programs.

"Ico-Alone" single nocturnal exchange to initiate peritoneal dialysis in patients with residual renal function-Five year, single centre experience

Full Text Available We analyzed the outcome of incremental dialysis with single nocturnal icodextrin exchange peritoneal dialysis (PD as the initial treatment for end-stage kidney failure in patients who have significant residual renal function. All adult patients opting for PD as renal replacement therapy, having residual renal function, and urinary KT/V of 1.0 were offered incremental dialysis with single nocturnal icodextrin exchange as initial treatment. Adequacy of dialysis was calculated at 1, 3, and 6 months and then 6 monthly. Patients were shifted to conventional PD if short of adequacy or if clinically indicated. Median period on "Ico-alone," peritonitis, exit site infection rates, and patient survival, while on this protocol, were calculated. These outcomes were compared with the cohort of contemporary patients on conventional PD. Thirteen patients were initiated on "Ico-alone" dialysis between October 2006 and October 2011. The baseline characteristics were similar when compared with cohort of conventional PD patients, except urine volume, which was more in "Ico-alone" group (1265 ± 316 vs. 551 ± 504, P = 0.000. Total KT/V at 3 months (1.63 ± 0.6 vs. 1.7 ± 0.2, P = 0.6 and at 1 year (1.64 ± 0.5 vs. 1.53 ± 0.3, P = 0.6 was similar to the cohort of conventional PD patients. Median period on "Ico-alone" was 9.6 months. Peritonitis rate was 1 episode in 56.22 vs 25.29 patient-months and exit site infection was 1 episode in 56.2 vs 189.71 patient-months in "Ico-alone" and conventional group, respectively. Patient survival was 42.84 months in "Ico-alone′ vs 25.29 months in conventional dialysis ( P = 0.01. In conclusion, single icodextrin exchange offers adequate dialysis in patients with residual renal function (KT/V = 1 for a median period of 9 months.

In New Zealand, patients receive treatment for end-stage renal disease (ESRD) within the tax-funded health system. All hospital and specialist outpatient services are free, while general practitioner consultations and pharmaceuticals prescribed outside of hospitals incur copayments. Total ESRD prevalence is 0.07%, half the U.S. rate, and the prevalence of home-based and self-care dialysis is the highest in the world. Medical staff are not subject to direct financial incentives that could affect treatment choice. Estimated total expenditure per ESRD patient is relatively low. Funding constraints encourage physicians and patients to consider the probable benefit of dialysis for a patient before treatment is prescribed.

Scheduled initiation of dialysis with a permanent access was considered as planned RRT start.Modality information (80% of patients and renal education (87% were more frequent (p8.2 ml/min, >2 months between information and RRT initiation and with vascular etiology after adjustment for age and gender. "Optimal care," defined as ICS follow-up >12 months plus modality information and P start, occurred in 23%.Despite the high rate of late referrals, information and education were widely provided. However, NP start was high and related to late referral and may explain the low frequency of PD.

Full Text Available Abstract Background A cost-effectiveness analysis of timely dialysis referral after renal transplant failure was undertaken from the perspective of the Public Administration. The current Spanish situation, where all the patients undergoing graft function loss are referred back to dialysis in a late manner, was compared to an ideal scenario where all the patients are timely referred. Methods A Markov model was developed in which six health states were defined: hemodialysis, peritoneal dialysis, kidney transplantation, late referral hemodialysis, late referral peritoneal dialysis and death. The model carried out a simulation of the progression of renal disease for a hypothetical cohort of 1,000 patients aged 40, who were observed in a lifetime temporal horizon of 45 years. In depth sensitivity analyses were performed in order to ensure the robustness of the results obtained. Results Considering a discount rate of 3 %, timely referral showed an incremental cost of 211 €, compared to late referral. This cost increase was however a consequence of the incremental survival observed. The incremental effectiveness was 0.0087 quality-adjusted life years (QALY. When comparing both scenarios, an incremental cost-effectiveness ratio of 24,390 €/QALY was obtained, meaning that timely dialysis referral might be an efficient alternative if a willingness-to-pay threshold of 45,000 €/QALY is considered. This result proved to be independent of the proportion of late referral patients observed. The acceptance probability of timely referral was 61.90 %, while late referral was acceptable in 38.10 % of the simulations. If we however restrict the analysis to those situations not involving any loss of effectiveness, the acceptance probability of timely referral was 70.10 %, increasing twofold that of late referral (29.90 %.

Normochromic normocytic anemia is a common complication in chronic kidney disease (CKD) and is associated with many adverse clinical consequences. Erythropoiesis-stimulating agents (ESAs) act to replace endogenous erythropoietin for patients with end-stage renal disease having anemia. Today, ESAs remain the main tool for treating anemia associated with CKD. In current practice, the use of ESA is not limited to the patients on renal replacement therapy but has extended to nondialysis patients under palliative care (PC). Current evidence on ESA usage in patients with CKD decided to forego dialysis often have to take reference from studies conducted in other groups of patients with CKD, including pre-dialysis patients and those on renal replacement therapy. There is paucity of studies targeting use of ESAs in renal PC patients. Small-scale retrospective study in renal PC patients had suggested clinical advantage of ESAs in terms of hemoglobin improvement, reduction in fatigue, and hospitalization rate. With the expected growth in elderly patients with CKD decided to forego dialysis and manage conservatively, there remains an urgent need to call for large-scale prospective trial in exploring efficacy of ESAs in this population, targeting on quality of life and symptoms improvement outcome. This article also reviews the mechanism of action, pharmacology, adverse effects, and clinical trial evidence for ESA in patients with CKD under renal PC.

Full Text Available Background: In order to reduce the cardiovascular risk, morbidity and mortality of peritoneal dialysis (PD, a minimal level of small-solute clearances as well as a sodium and water balance are needed. The peritoneal dialysis solutions used in combination have reduced the complications and allow for a long-time function of the peritoneal membrane, and the preservation of residual renal function (RRF in patients on peritoneal dialysis (PD is crucial for the maintenance of life quality and long-term survival. This retrospective cohort study reviews our experience in automatic peritoneal dialysis (APD patients, with end-stage renal disease (ESRD secondary to diabetic nephropathy (DN in comparison to non-diabetic nephropathy (NDN, using different PD solutions in combination. Design: Fifty-two patients, 29 diabetic and 23 non-diabetic, were included. The follow-up period was 24 months, thus serving as their own control. Results: The fraction of renal urea clearance (Kt relative to distribution volume (V (or total body water (Kt/V, or creatinine clearance relative to the total Kt/V or creatinine clearance (CrCl decreases according to loss of RRF. The loss of the slope of RRF is more pronounced in DN than in NDN patients, especially at baseline time interval to 12 months (loss of 0.29 mL/month vs. 0.13 mL/month, respectively, and is attenuated in the range from 12 to 24 months (loss of 0.13 mL/month vs. 0.09 mL/month, respectively. Diabetic patients also experienced a greater decrease in urine output compared to non-diabetic, starting from a higher baseline urine output. The net water balance was adequate in both groups during the follow up period. Regarding the balance sodium, no inter-group differences in sodium excretion over follow up period was observed. In addition, the removal of sodium in the urine output decreases with loss of renal function. The average concentration of glucose increase in the cycler in both groups (DN: baseline 1.44 ± 0

Renal replacement therapy (RRT) for Brazilian children with uraemia has been utilized since 1970 in the state of Rio Grande do Sul. One hundred and eighty patients receiving this therapy between 1970 and 1988 have been reviewed. The annual acceptance rate of new paediatric patients in this period increased from 0.6 to 6.5 patients per million child population. Glomerulonephritis (36.1%) and pyelonephritis including urological anomalies (31.7%) were the most frequent causes of end-stage renal disease. Outpatient hospital haemodialysis was the primary form of dialytic treatment in patients 5-15 years of age. Continuous ambulatory peritoneal dialysis was more often used in patients less than 5 years of age. The survival after 1 year on dialysis was 79.9% for children aged 5-15 years starting dialysis during the period 1985-1988. Fluid overload with congestive heart failure and infection were the main causes of death in children on dialysis. Eighty-four children received 93 grafts; only 14 (15%) were from cadaveric donors. One-year patient and graft survival of first living-related donor transplants were 92.2% and 78.5% respectively during the period 1985-1988. Infection accounted for 43.5% of deaths after transplantation. We conclude that RRT is becoming increasingly successful for children in our region but that greater emphasis upon patient compliance with all forms of RRT and upon cadaver kidney donation is needed.

The ESRD Prospective Payment System introduced two incentives to increase home dialysis use: bundling injectable medications into a single payment for treatment and paying for home dialysis training. We evaluated the effects of the ESRD Prospective Payment System on home dialysis use by patients starting dialysis in the United States from January 1, 2006 to August 31, 2013. We analyzed data on dialysis modality, insurance type, and comorbidities from the United States Renal Data System. We estimated the effect of the policy on home dialysis use with multivariable logistic regression and compared the effect on Medicare Parts A/B beneficiaries with the effect on patients with other types of insurance. The ESRD Prospective Payment System associated with a 5.0% (95% confidence interval [95% CI], 4.0% to 6.0%) increase in home dialysis use by the end of the study period. Home dialysis use increased by 5.8% (95% CI, 4.3% to 6.9%) among Medicare beneficiaries and 4.1% (95% CI, 2.3% to 5.4%) among patients covered by other forms of health insurance. The difference between these groups was not statistically significant (1.8%; 95% CI, -0.2% to 3.8%). Conversely, in both populations, the training add-on did not associate with increases in home dialysis use beyond the effect of the policy. The ESRD Prospective Payment System bundling, but not the training add-on, associated with substantial increases in home dialysis, which were identical for both Medicare and non-Medicare patients. These spill-over effects suggest that major payment changes in Medicare can affect all patients with ESRD. Copyright © 2017 by the American Society of Nephrology.

Integrated Care Settings (ICS) provide a holistic approach to the transition from chronic kidney disease into renal replacement therapy (RRT), offering at least both types of dialysis. To analyze which factors determine type of referral, modality provision and dialysis start on final RRT in ICS clinics. Retrospective analysis of 626 patients starting dialysis in 25 ICS clinics in Poland, Hungary and Romania during 2012. Scheduled initiation of dialysis with a permanent access was considered as planned RRT start. Modality information (80% of patients) and renal education (87%) were more frequent (pregression analysis, P start (p≤0.05) was associated with early referral, eGFR >8.2 ml/min, >2 months between information and RRT initiation and with vascular etiology after adjustment for age and gender. "Optimal care," defined as ICS follow-up >12 months plus modality information and P start, occurred in 23%. Despite the high rate of late referrals, information and education were widely provided. However, NP start was high and related to late referral and may explain the low frequency of PD.

Mortality on dialysis varies greatly worldwide, with patient-level factors explaining only a small part of this variation. The aim of this study was to examine the association of national-level macroeconomic indicators with the mortality of incident dialysis populations and explore potential explanations through renal service indicators, incidence of dialysis, and characteristics of the dialysis population. Aggregated unadjusted survival probabilities were obtained from 22 renal registries worldwide for patients starting dialysis in 2003-2005. General population age and health, macroeconomic indices, and renal service organization data were collected from secondary sources and questionnaires. Linear modeling with log-log transformation of the outcome variable was applied to establish factors associated with survival on dialysis. Two-year survival on dialysis ranged from 62.3% in Iceland to 89.8% in Romania. A higher gross domestic product per capita (hazard ratio=1.02 per 1000 US dollar increase), a higher percentage of gross domestic product spent on healthcare (1.10 per percent increase), and a higher intrinsic mortality of the dialysis population (i.e., general population-derived mortality risk of the dialysis population in that country standardized for age and sex; hazard ratio=1.04 per death per 10,000 person years) were associated with a higher mortality of the dialysis population. The incidence of dialysis and renal service indicators were not associated with mortality on dialysis. Macroeconomic factors and the intrinsic mortality of the dialysis population are associated with international differences in the mortality on dialysis. Renal service organizational factors and incidence of dialysis seem less important.

The aim of the study was the subjective assessment of the quality of life (QoL) of 140 patients treated with dialysis (peritoneal dialysis and hemodialysis). Chronic kidney disease and the methods of its treatment play an important part in shaping the QoL of patients receiving dialysis. As a result, kidney failure causes many limitations in patients' physical, mental, and social activities. The instrument to measure the QoL was the authors' own questionnaire made on the basis of Kidney Disease and Quality of Life Short Form version 1.2 (KDQOL - SF 1.2) and their selection of areas influencing the perceived QoL of chronically ill patients. The research showed that patients receiving peritoneal dialysis assessed their QoL in its different dimensions as much higher than patients receiving hemodialysis. The parameter having the biggest negative impact on the QoL of patients receiving hemodialysis was an impeded possibility to continue work or studies and a change of life plans. The will to live was more highly assessed by patients receiving peritoneal dialysis as compared to patients receiving hemodialysis. In order to improve the functioning of hemodialysis patients in a manner most similar to healthy persons, the renal replacement therapy should consider patients' individual needs and expectations, ie, guarantee flexible hours of work or study and of receiving dialysis. In addition, patients treated with hemodialysis should receive psychological care, in particular those demonstrating emotional problems, in order to achieve better results in therapy and improve their QoL.

Home-based renal replacement therapy (RRT) [peritoneal dialysis (PD) and home hemodialysis (HHD)] offers independent quality of life and clinical advantages compared to conventional in-center hemodialysis. However, follow-up may be less complete for home dialysis patients following a change in care settings such as post hospitalization. We aim to implement a Home Dialysis Virtual Ward (HDVW) strategy, which is targeted to minimize gaps of care. The HDVW Pilot Study will enroll consecutive PD and HHD patients who fulfilled any one of our inclusion criteria: 1. following discharge from hospital, 2. after interventional procedure(s), 3. prescription of anti-microbial agents, or 4. following completion of home dialysis training. Clinician-led telephone interviews are performed weekly for 2 weeks until VW discharge. Case-mix (modified Charlson Comorbidity Index), symptoms (the modified Edmonton Symptom Assessment Scale) and patient satisfaction are assessed serially. The number of VW interventions relating to eight pre-specified domains will be measured. Adverse events such as re-hospitalization and health-services utilization will be ascertained through telephone follow-up after discharge from the VW at 2, 4, 12 weeks. The VW re-hospitalization rate will be compared with a contemporary cohort (matched for age, gender, renal replacement therapy and co-morbidities). Our protocol has been approved by research ethics board (UHN: 12-5397-AE). Written informed consent for participation in the study will be obtained from participants. This report serves as a blueprint for the design and implementation of a novel health service delivery model for home dialysis patients. The major goal of the HDVW initiative is to provide appropriate and effective supports to medically complex patients in a targeted window of vulnerability. (NCT01912001).

The nature of end-stage renal disease and the need for continuous ambulatory peritoneal dialysis require patients to manage various aspects of the disease, its symptoms and treatment. After attending a training programme, patients are expected to adhere to the renal therapeutic regimen and manage their disease with the knowledge and skills learned. While patients are the stakeholders of their health and related behaviour, their perceptions of adherence and how they adhere to their renal therapeutic regimen remains unexplored. To understand adherence from patients' perspectives and to describe changes in adherence to a therapeutic regimen among patients undergoing continuous ambulatory peritoneal dialysis. This study used a mixed methods design with two phases - a survey in phase I and semi-structured interviews in phase II. This paper presents phase II of the study. The study was conducted at a renal unit of an acute hospital in Hong Kong. Based on the phase I survey results, maximum variation sampling was employed to purposively recruit 36 participants of different genders (18 males, 18 females), ages (35-76 years), and lengths of dialysis experience (11-103 months) for the phase II interviews. Data were collected by tape-recorded semi-structured interviews. Content analysis was employed to analyse the transcribed data. Data collection and analysis were conducted simultaneously. Adherence was a dynamic process with three stages. At the stage of initial adherence, participants attempted to follow instructions but found that strict persistent adherence was impossible. After the first 2-6 months of dialysis, participants entered the stage of subsequent adherence, when they adopted selective adherence through experimenting, monitoring and making continuous adjustments. The stage of long-term adherence commenced after 3-5 years of dialysis, when participants were able to assimilate the modified therapeutic regimen into everyday life. The process of adherence was

♦ Health-care systems must attempt to provide appropriate, high-quality, and economically sustainable care that meets the needs and choices of patients with end-stage renal disease (ESRD). France offers 9 different modalities of dialysis, each characterized by dialysis technique, the extent of professional assistance, and the treatment site. The aim of this study was 1) to describe the various dialysis modalities in France and the patient characteristics associated with each of them, and 2) to analyze their regional patterns to identify possible unexpected associations between case-mixes and dialysis modalities. ♦ The clinical characteristics of the 37,421 adult patients treated by dialysis were described according to their treatment modality. Agglomerative hierarchical cluster analysis was used to aggregate the regions into clusters according to their use of these modalities and the characteristics of their patients. ♦ The gradient of patient characteristics was similar from home hemodialyis (HD) to in-center HD and from non-assisted automated peritoneal dialysis (APD) to assisted continuous ambulatory peritoneal dialysis (CAPD). Analyzing their spatial distribution, we found differences in the patient case-mix on dialysis across regions but also differences in the health-care provided for them. The classification of the regions into 6 different clusters allowed us to detect some unexpected associations between case-mixes and treatment modalities. ♦ The 9 modalities of treatment available make it theoretically possible to adapt treatment to patients' clinical characteristics and abilities. However, although we found an overall appropriate association of dialysis modalities to the case-mix, major inter-region heterogeneity and the low rate of peritoneal dialysis (PD) and home HD suggest that factors besides patients' clinical conditions impact the choice of dialysis modality. The French organization should now be evaluated in terms of patients' quality of

Dialysis prolongs the life of people with end-stage renal disease (ESRD), but for patients who are elderly and suffer multiple comorbid illnesses the benefits of dialysis may be outweighed by its negative consequences. Non-dialytic conservative management has therefore become an alternative treatment route, yet little is known on patients' experience with choosing end-of-life treatment. To gain insight into the decision-making process leading to opting out of dialysis and the experience with conservative non-dialytic management from the patients' perspective. Qualitative study using semi-structured interviews. Interpretative phenomenological analysis was undertaken as the framework for data analysis. N = 9 ESRD participants who have taken the decision to forego dialysis were recruited from the advanced care programme under the National Healthcare Group, Singapore. Participants discussed life since ESRD diagnosis, and the personal and contextual factors that led them to choose conservative management. The perceived physical and financial burden of dialysis both for the individual but most importantly for their family, uncertainty over likely gains over risks which were fuelled by communication of negative dialysis stories of others, coupled with sense of life completion and achievement led them to refuse dialysis. All participants took ownership of their decision despite contrary advice by doctors and were content with their decision and current management. Study highlights the factors driving patients' decisions for conservative non-dialytic management over dialysis to allow medical professionals to offer appropriate support to patients through their decision-making process and in caring them for the rest of their lives. © 2013 John Wiley & Sons Ltd.

Metabolic acidosis is a common consequence of end-stage renal disease (ESRD) which may result in a substantial adverse outcome. The effect of oral bicarbonate on the preservation of residual renal function (RRF) in peritoneal dialysis (PD) patients has been rarely reported. We randomly assigned 40 continuous ambulatory peritoneal dialysis (CAPD) patients to the oral bicarbonate group or placebo group at a 1: 1 ratio. All enrollments were followed for a duration of 104 weeks. We took residual creatinine clearance (CCr), a measure of residual renal function (RRF), as the primary outcome. Residual CCr was calculated as the average of urea and creatinine clearance from a 24-hour urine collection. Thirteen patients in the placebo group and 15 patients in the treatment group completed the 104 weeks of follow-up with a comparable dropout rate (placebo group: 35% vs treatment group: 25%). Compared with the placebo group, serum bicarbonate in treatment group was significantly increased at each time point, and oral bicarbonate resulted in a slower declining rate of residual CCr (F=5.113, p=0.031). Baseline residual CCr at enrollment also had a significant effect on residual CCr (F=168.779, Pcalculate a comorbidity score had no significant effect on residual CCr loss (F=0.168, P=0.685). Oral bicarbonate may have a RRF preserving effect in CAPD patients, and a normal to high level of serum bicarbonate (≥24mmol/L) may be appropriate for RRF preservation. © 2017 The Author(s).

Patients with end-stage renal disease report infrequent end-of-life discussions, and nephrology trainees report feeling unprepared for end-of-life decision making, but the views of dialysis medical directors have not been studied. Our objective is to understand dialysis medical directors' views and practice patterns on end-of-life decision making for patients with ESRD. We administered questionnaires to dialysis medical directors during medical director meetings of three different dialysis organizations in 2013. Survey questions corresponded to recommendations from the Renal Physicians Association clinical practice guidelines on initiation and withdrawal of dialysis. There were 121 medical director respondents from 28 states. The majority of respondents felt "very prepared" (66%) or "somewhat prepared" (29%) to participate in end-of-life decisions and most (80%) endorsed a model of shared decision making. If asked to do so, 70% of the respondents provided prognostic information "often" or "nearly always." For patients with a poor prognosis, 36% of respondents would offer a time-limited trial of dialysis "often" or "nearly always", while 56% of respondents would suggest withdrawal from dialysis "often" or "nearly always" for those with a poor prognosis currently receiving dialysis therapy. Patient resistance and fear of taking away hope were the most commonly cited barriers to end-of-life discussions. Views and reported practice patterns of medical directors are consistent with clinical practice guidelines for end-of-life decision making for patients with end-stage renal disease but inconsistent with patient perceptions. © The Author(s) 2016.

Risk of serous retinal detachment in patients with end-stage renal disease on dialysis.

Yuh-Shin Chang

Full Text Available The aim of this retrospective, nationwide, matched cohort study was to investigate the association of serous retinal detachment with having end-stage renal disease (ESRD while on dialysis. The cohort study included 94,024 patients with ESRD on dialysis registered between January 2000 to December 2009 in the Taiwan National Health Insurance Research Database. An age- and sex-matched control group comprised 94,024 patients selected from the Taiwan Longitudinal Health Insurance Database 2000. Information for each patient was collected from the index date until December 2011. Twenty-seven ESRD patients and 11 controls developed serous retinal detachment (P < 0.001 during follow-up, demonstrating a significantly increased risk of serous retinal detachment in patients with ESRD on dialysis compared with controls (incidence rate ratio = 3.39, 95% confidence interval [CI] = 1.68-6.83. After adjustment for potential confounders, patients were 3.86 times more likely to develop serous retinal detachment than the full cohort (adjusted HR = 3.86, 95% CI = 1.15-12.96. In conclusion, patients with ESRD on dialysis demonstrate an increased risk of serous retinal detachment. Interdisciplinary collaboration between nephrologists and ophthalmologists is important to deal with serous retinal detachment in patients with ESRD on dialysis and prevent impairments of visual acuity.

The end-stage renal disease Medical Evidence Report serves as a source of comorbid condition data for risk adjustment of quality metrics. We sought to compare comorbid condition data in the Medical Evidence Report around dialysis therapy initiation with diagnosis codes in Medicare claims. Observational cohort study using US Renal Data System data. Medicare-enrolled elderly (≥66 years) patients who initiated maintenance dialysis therapy July 1 to December 31, 2007, 2008, or 2009. 12 comorbid conditions ascertained from claims during the 6 months before dialysis therapy initiation, the Medical Evidence Report, and claims during the 3 months after dialysis therapy initiation. None. Comorbid condition prevalence according to claims before dialysis therapy initiation generally exceeded prevalence according to the Medical Evidence Report. The κ statistics for comorbid condition designations other than diabetes ranged from 0.06 to 0.43. Discordance of designations was associated with age, race, sex, and end-stage renal disease Network. During 23,930 patient-years of follow-up from 4 to 12 months after dialysis therapy initiation (8,930 deaths), designations from claims during the 3 months after initiation better discriminated risk of death than designations from the Medical Evidence Report (C statistics of 0.674 vs 0.616). Between the Medical Evidence Report and claims, standardized mortality ratios changed by >10% for more than half the dialysis facilities. Neither the Medical Evidence Report nor diagnosis codes in claims constitute a gold standard of comorbid condition data; results may not apply to nonelderly patients or patients without Medicare coverage. Discordance of comorbid condition designations from the Medical Evidence Report and claims around dialysis therapy initiation was substantial and significantly associated with patient characteristics, including location. These patterns may engender bias in risk-adjusted quality metrics. In lieu of the Medical

From January 2016, payment for oral-only renal medications (including phosphate binders and cinacalcet) was expected to be included in the new Medicare bundled end-stage renal disease (ESRD) prospective payment system (PPS). The implementation of the ESRD PPS has generated concern within the nephrology community because of the potential for inadequate funding and the impact on patient quality of care. To estimate the potential economic impact of the new Medicare bundled ESRD PPS reimbursement from the perspective of a large dialysis organization in the United States. We developed an interactive budget impact model to evaluate the potential economic implications of Medicare payment changes to large dialysis organizations treating patients with ESRD who are receiving phosphate binders. In this analysis, we focused on the budget impact of the intended 2016 integration of oral renal drugs, specifically oral phosphate binders, into the PPS. We also utilized the model to explore the budgetary impact of a variety of potential shifts in phosphate binder market shares under the bundled PPS from 2013 to 2016. The base model predicts that phosphate binder costs will increase to $34.48 per dialysis session in 2016, with estimated U.S. total costs for phosphate binders of over $682 million. Based on these estimates, a projected Medicare PPS $33.44 reimbursement rate for coverage of all oral-only renal medications (i.e., phosphate binders and cinacalcet) would be insufficient to cover these costs. A potential renal drugs and services budget shortfall for large dialysis organizations of almost $346 million was projected. Our findings suggest that large dialysis organizations will be challenged to manage phosphate binder expenditures within the planned Medicare bundled rate structure. As a result, large dialysis organizations may have to make treatment choices in light of potential inadequate funding, which could have important implications for the quality of care for patients

This article reviews the principal evidences about aluminum neurotoxicity in vitro, and some evidences in brain tissues of Alzheimer patients; and also show some studies realized with human that suffer renal deficiencies, dealing whit the principal osteodystrophy. The problem of analyzing low aluminum concentration in human fluids is overcome with very sensitive analytical methods as electrothermal atomic absorption spectrometry (ETAS) and voltammetric methods as Anodic Striping Voltammetry with complexing agents that easing adsorption over solid electrodes or mercury hanging drops. Is a vital question to know with accuracy the aluminum concentration in water used in hemodialysis or in fluids used in ambulatory peritoneal dialysis, as a first stage to prevent contamination by aluminum. So the prevention of contamination during sapling storage and analysis of biological fluids should be the first need and the sources of water used in renal dialysis keep be as clean as possible of aluminum contamination.

Methods In the PREPARE-1 cohort 547 incident pre-dialysis patients, referred as part of the usual care to outpatient clinics of eight Dutch hospitals, were included between 1999 and 2001 and followed until the start of RRT, mortality, or end of follow-up (January 1st 2008. Main outcomes were rate of decline in renal function, estimated as the slope of available eGFR measurements, and time until the start of RRT. Results A total of 508 patients, 57% men and median (IQR age of 63 (50-73 years, were available for analyses. Mean (SD decline in renal function was 0.35 (0.75 ml/min/1.73 m2/month.

Full Text Available Peritoneal dialysis (PD using an ordinary stylet cannula was studied in 253 patients (67% male and 33% female with age ranging from 3-67 years suffering from renal failure. The study was conducted between January 2007 and December 2012. The procedure was well tolerated by the patients. The desired aims of dialysis including improvement in chemistry were achieved in all surviving (94.5% cases. Mortality during PD was 5.5% and was related to the underlying causes of renal failure. Peritonitis seen in 30% cases was the commonest complication. Other complications in order of frequency were, hypokalemia (8%, severe hyperglycemia in diabetic patients (6%, and sever hypovolemia (5%, pericatheter leak (5% and catheter blockage (2%. Perforation of the bowel, a serious complication occurring during insertion of the PD cannula was not seen in any of the cases. It is concluded from the study that PD is a simple and cost effective alternative to hemodialysis and have special advantages in the current set-up of the institute. The objective of our work was to study the results and complications of peritoneal dialysis in light of its efficacy as an alternative form of renal replacement therapy (RRT to hemodialysis.

Full Text Available Background. The purpose of this study was to analyze the factors associated with receiving peritoneal dialysis (PD in patients with incident end-stage renal disease (ESRD in a hospital in Southern Taiwan. Methods. The study included all consecutive patients with incident ESRD who participated in a multidisciplinary predialysis education (MPE program and started their first dialysis therapy between January 1, 2008, and June 30, 2013, in the study hospital. We provided small group teaching sessions to advanced CKD patients and their family to enhance understanding of various dialysis modalities. Multivariate logistic regression models were used to analyze the association of patient characteristics with the chosen dialysis modality. Results. Of the 656 patients, 524 (80% chose hemodialysis and 132 chose PD. Our data showed that young age, high education level, and high scores of activities of daily living (ADLs were positively associated with PD treatment. Patients who received small group teaching sessions had higher percentages of PD treatment (30.5% versus 19.5%; P=0.108 and preparedness for dialysis (61.1% versus 46.6%; P=0.090. Conclusion. Young age, high education level, and high ADL score were positively associated with choosing PD. Early creation of vascular access may be a barrier for PD.

Renin-angiotensin-system (RAS) blockade is thought to slow renal progression in patients with chronic kidney disease (CKD). However, it remains uncertain if the habitual use of RAS inhibitors affects renal progression and outcomes in pre-dialysis patients with advanced CKD. In this multicenter retrospective cohort study, we identified 2,076 pre-dialysis patients with advanced CKD (stage 4 or 5) from a total of 33,722 CKD patients. RAS blockade users were paired with non-users for analyses using inverse probability of treatment-weighted (IPTW) and propensity score (PS) matching. The outcomes were renal death, all-cause mortality, hospitalization for hyperkalemia, and interactive factors as composite outcomes. RAS blockade users showed an increased risk of renal death in PS-matched analysis (hazard ratio [HR], 1.381; 95% CI, 1.071-1.781; P = 0.013), which was in agreement with the results of IPTW analysis (HR, 1.298; 95% CI, 1.123-1.500; P renal outcome without improving all-cause mortality. Further studies are warranted to determine whether withholding RAS blockade may lead to better outcomes in these patients.

A low rate of adherence to treatment is a widespread problem of great clinical relevance among dialysis patients. The objective of the present study is to determine the relationship between adherence, emotional state (depression, anxiety, and perceived stress), and health-related quality of life (HRQOL) in renal patients undergoing dialysis. Two patient groups (30 in hemodialysis and 31 in peritoneal dialysis) participated in this study. We evaluated aspects of adherence, depression, anxiety, perceived stress, and HRQOL with self-report and standardized instruments. Peritoneal dialysis patients reported significantly higher levels of adherence to treatment and better HRQOL in Physical Function and Bodily Pain domains. Depression level is associated with HRQOL indicators. We did not find any differences regarding specific adherence to antihypertensive and phosphate binder drugs or in psychological variables depending on the modality of dialysis. Patients with adherence to antihypertensive drugs show better physical HRQOL. The predictors of HRQOL in dialysis patients were: work, gender and depression. Our results suggest that the modality of dialysis does not differentially affect the emotional state or specific adherence to drugs, but it is nevertheless related to their overall adherence to treatment and to their HRQOL.

Previous reports showed an increased early mortality after chronic dialysis initiation among the end-stage renal disease (ESRD) population. We hypothesized that ESRD patients in the Military Health System (MHS) would have greater access to pre-ESRD care and hence better survival rates during this early high-risk period. In this retrospective cohort study, using the US Renal Data System database, we identified 1,256,640 patients initiated on chronic dialysis from January 2, 2004 through December 31, 2014, from which a bootstrap sample of 3,984 non-MHS incident dialysis patients were compared with 996 MHS patients. We assessed care by a nephrologist and dietitian, erythropoietin administration, and vascular access use at dialysis initiation as well as all-cause mortality as outcome variables. MHS patients were significantly more likely to have had pre-ESRD nephrology care (adjusted OR [aOR] 2.9; 95% CI 2.3-3.7) and arteriovenous fistula used at dialysis initiation (aOR 2.2; 95% CI 1.7-2.7). Crude mortality rates peaked between the 4th and the 8th week for both cohorts but were reduced among MHS patients. The baseline adjusted Cox model showed significantly lower death rates among MHS vs. non-MHS patients at 6, 9, and 12 months. This survival advantage among MHS patients was attenuated after further adjustment for pre-ESRD nephrology care and dialysis vascular access. MHS patients had improved survival within the first 12 months compared to the general ESRD population, which may be explained in part by differences in pre-ESRD nephrology care and vascular access types. © 2017 S.

Continuous renal replacement therapies have practical and theoretical advantages compared with conventional intermittent hemodialysis in hemodynamically unstable or severely catabolic patients with acute renal failure (ARF). Sustained low-efficiency dialysis (SLED) is a hybrid modality introduced July 1998 at the University of Arkansas for Medical Sciences that involves the application of a conventional hemodialysis machine with reduced dialysate and blood flow rates for 12-hour nocturnal treatments. Nine critically ill patients with ARF were studied during a single SLED treatment to determine delivered dialysis dose and the most appropriate model for the description of urea kinetics during treatment. Five patients were men, mean Acute Physiology and Chronic Health Evaluation (APACHE) II score was 28.9 and mean weight was 92.5 kg. Kt/V was determined by the reference method of direct dialysate quantification (DDQ) combined with an equilibrated postdialysis plasma water urea nitrogen (PUN) concentration and four other methods that were either blood or dialysate based, single or double pool, or model independent (whole-body kinetic method). Solute removal indices (SRIs) were determined from net urea removal and urea distribution volume supplied from DDQ (reference method) and by mass balance using variables supplied from blood-based formal variable-volume single-pool (VVSP) urea kinetic modeling. Equivalent renal urea clearances (EKRs) were calculated from urea generation rates and time-averaged concentrations for PUN based on weekly mass balance with kinetic variables supplied by either DDQ (reference method) or formal blood-based VVSP modeling. Mean Kt/V determined by the reference method was 1.40 and not significantly different when determined by formal VVSP modeling, DDQ using an immediate postdialysis PUN, or the whole-body kinetic method. Correction of single-pool Kt/V by a Daugirdas rate equation did not yield plausible results. Mean SRI and EKR by the

An increase in the dialysis programme expenditure is expected in most countries given the continued rise in the number of people with end-stage renal disease (ESRD) globally. Since chronic peritoneal dialysis (PD) therapy is relatively less expensive compared with haemodialysis (HD) and because there is no survival difference between PD and HD, identifying factors associated with PD use is important. Incidence counts for the years 2003-05 were available from 36 countries worldwide. We studied associations of population characteristics, macroeconomic factors and renal service indicators with the percentage of patients on PD at Day 91 after starting dialysis. With linear regression models, we obtained relative risks (RRs) with 95% confidence intervals (CIs). The median percentage of incident patients on PD was 12% (interquartile range: 7-26%). Determinants independently associated with lower percentages of patients on PD were as follows: patients with diabetic kidney disease (per 5% increase) (RR 0.93; 95% CI 0.89-0.97), health expenditure as % gross domestic product (per 1% increase) (RR 0.93; 95% CI 0.87-0.98), private-for-profit share of HD facilities (per 1% increase) (RR 0.996; 95% CI 0.99-1.00; P = 0.04), costs of PD consumables relative to staffing (per 0.1 increase) (RR 0.97; 95% CI 0.95-0.99). The factors associated with a lower percentage of patients on PD include higher diabetes prevalence, higher healthcare expenditures, larger share of private-for-profit centres and higher costs of PD consumables relative to staffing. Whether dialysis modality mix can be influenced by changing healthcare organization and funding requires additional studies.

♦ BACKGROUND: Increased demand for treatment of end-stage kidney disease has largely been accommodated by a costly increase in satellite hemodialysis (SHD) in most jurisdictions. In the Australian State of Victoria, a marked regional variation in the uptake of home-based dialysis suggests that use of home therapies could be increased as an alternative to SHD. An earlier strategy based solely on increased remuneration had failed to increase uptake of home therapies. Therefore, the public dialysis funder adopted the incidence and prevalence of home-based dialysis therapies as a key performance indicator (KPI) for its health services to encourage greater uptake of home therapies. ♦ METHODS: A KPI data collection and bench-marking program was established in 2012 by the Victorian Department of Health and Human Services, with data provided monthly by all renal units in Victoria using a purpose-designed website portal. A KPI Working Group was responsible for analyzing data each quarter and ensuring indicators remained accurate and relevant and each KPI had clear definitions and targets. We present a prospective, observational study of all dialysis patients in Victoria over a 4-year period following the introduction of the renal KPI program, with descriptive analyses to evaluate the proportion of patients using home therapies as well as home dialysis modality survival. ♦ RESULTS: Following the introduction of the KPI program, the net growth of dialysis patient numbers in Victoria remained stable over 4 years, at 75 - 80 per year (approximately 4%). However, unlike the previous decade, about 40% of this growth was through an increase in home dialysis, which was almost exclusively peritoneal dialysis (PD). The increase was identified particularly in the young (20 - 49) and the elderly (> 80). Disappointingly, however, 67% of these incident patients ceased PD within 2 years of commencement, 46% of whom transferred to SHD. ♦ CONCLUSIONS: Introduction of a KPI program

Proposals to make decisions about coverage of new technology by comparing the technology's incremental cost-effectiveness with the traditional benchmark of dialysis imply that the incremental cost-effectiveness ratio of dialysis is seen a proxy for the value of a statistical year of life. The frequently used ratio for dialysis has, however, not been updated to reflect more recently available data on dialysis. We developed a computer simulation model for the end-stage renal disease population and compared cost, life expectancy, and quality adjusted life expectancy of current dialysis practice relative to three less costly alternatives and to no dialysis. We estimated incremental cost-effectiveness ratios for these alternatives relative to the next least costly alternative and no dialysis and analyzed the population distribution of the ratios. Model parameters and costs were estimated using data from the Medicare population and a large integrated health-care delivery system between 1996 and 2003. The sensitivity of results to model assumptions was tested using 38 scenarios of one-way sensitivity analysis, where parameters informing the cost, utility, mortality and morbidity, etc. components of the model were by perturbed +/-50%. The incremental cost-effectiveness ratio of dialysis of current practice relative to the next least costly alternative is on average $129,090 per quality-adjusted life-year (QALY) ($61,294 per year), but its distribution within the population is wide; the interquartile range is $71,890 per QALY, while the 1st and 99th percentiles are $65,496 and $488,360 per QALY, respectively. Higher incremental cost-effectiveness ratios were associated with older age and more comorbid conditions. Sensitivity to model parameters was comparatively small, with most of the scenarios leading to a change of less than 10% in the ratio. The value of a statistical year of life implied by dialysis practice currently averages $129,090 per QALY ($61,294 per year), but

Longer dialysis session length (treatment time, TT) has been associated with better survival among hemodialysis (HD) patients. The impact of TT on clinical markers that may contribute to this survival advantage is not well known. Using data from the international Dialysis Outcomes and Practice Patterns Study, we assessed the association of TT with clinical outcomes using both standard regression analyses and instrumental variable approaches. The study included 37,414 patients on in-center HD three times per week with prescribed TT from 120 to 420 min. Facility mean TT ranged from 214 min in the USA to 256 min in Australia-New Zealand. Accounting for country effects, mortality risk was lower for patients with longer TT {hazard ratio for every 30 min: all-cause mortality: 0.94 [95% confidence interval (CI): 0.92-0.97], cardiovascular mortality: 0.95 (95% CI: 0.91-0.98) and sudden death: 0.93 (95% CI: 0.88-0.98)}. Patients with longer TT had lower pre- and post-dialysis systolic blood pressure, greater intradialytic weight loss, higher hemoglobin (for the same erythropoietin dose), serum albumin and potassium and lower serum phosphorus and white blood cell counts. Similar associations were found using the instrumental variable approach, although the positive associations of TT with weight loss and potassium were lost. Favorable levels of a variety of clinical markers may contribute to the better survival of patients receiving longer TT. These findings support longer TT prescription in the setting of in-center, three times per week HD.

An electrical or water supply and a blood purification machine are required for renal replacement therapy. There is a possibility that acute kidney injury can occur in large numbers and on a wide scale in the case of a massive earthquake, and there is the potential risk that the current supply will be unable to cope with acute kidney injury cases. However, non-machinery dialysis requires exclusive circuits and has the characteristic of not requiring the full-scale dialysis machines. We performed perfusion experiments that used non-machinery dialysis and recent blood purification machines in 30-min intervals, and the effectiveness of non-machinery dialysis was evaluated by the assessing the removal efficiency of potassium, which causes lethal arrhythmia during acute kidney injury. The non-machinery dialysis potassium removal rate was at the same level as continuous blood purification machines with a dialysate flow rate of 5 L/h after 15 min and continuous blood purification machines with a dialysate flow rate of 3 L/h after 30 min. Non-machinery dialysis required an exclusive dialysate circuit, the frequent need to replace bags, and new dialysate exchanged once every 30 min. However, it can be seen as an effective renal replacement therapy for crush-related acute kidney injury patients, even in locations or facilities not having the full-scale dialysis machines.

The aim of this study was to investigate regional cerebral blood flow (rCBF) changes of end-stage renal disease (ESRD) patients with depressive symptoms during dialysis. Fourteen patients with ESRD underwent Tc-99m ethylcysteinate dimer (Tc-99m ECD) brain single photon emission computed tomography (SPECT) and were evaluated the severity of depressive mood at pre-dialytic period and at least 6 months after dialysis initiation. rCBF was analyzed using statistical parametric mapping (SPM) in brain SPECT image. The responder was defined as a decrease of ≥25% in Hamilton Depression Rating Scale (HDRS) score from baseline HDRS score. Pre-dialysis brain SPECT did not show any rCBF differences between responders and non-responders. The follow-up brain SPECT revealed a significant higher perfusion in left middle temporal gyrus of responder group when compared with non-responder (hemisphere coordinate X, Y, Z; -58, -2, -16, peak Z=3.36, p=0.046). In responder, a significant increase in rCBF was found in right parahippocampal gyrus (hemisphere coordinate X, Y, Z; 30, -40, -14, peak Z=3.51, p=0.043). In non-responder, there were significant decreases in rCBF in left superior frontal gyrus (hemisphere coordinate X, Y, Z; -22, 30, 42, peak Z=3.86, p=0.032) and right orbitofrontal cortex (hemisphere coordinate X, Y, Z; 10, 58, -6, peak Z=3.81, p=0.046). The present findings showed the characteristic patterns of rCBF changes in depressive ESRD patients having maintenance dialysis. Further investigations in brain blood flow and glucose metabolism are needed to elucidate the effect of dialysis itself and the difference of according to dialysis modality in patients having depression and ESRD.

Patients with end-stage renal disease (ESRD) frequently require urgent-start dialysis. Recent evidence suggests that peritoneal dialysis (PD) might be a feasible alternative to hemodialysis (HD) in these patients, including in older patients. This retrospective study enrolled patients aged > 65 years with ESRD who underwent urgent dialysis without functional vascular access or PD catheter at a single center, from January 2011 to December 2014. Patients were grouped based on their dialysis modality (PD or HD). Patients unable to tolerate PD catheter insertion or wait for PD were excluded. Each patient was followed for at least 30 days after catheter insertion. Short-term (30-day) dialysis-related complications and patient survival were compared between the 2 groups. A total of 94 patients were enrolled, including 53 (56.4%) who underwent PD. The incidence of dialysis-related complications during the first 30 days was significantly lower in PD compared with HD patients (3 [5.7%] vs 10 [24.4%], p = 0.009). Logistic regression identified urgent-start HD as an independent risk factor for dialysis-related complications compared with urgent-start PD (odds ratio 4.760 [1.183 - 19.147], p = 0.028). The 6-, 12-, 24-, and 36-month survival rates in the PD and HD groups were 92.3% vs 94.6%, 82.4% vs 81.3%, 75.7% vs 74.2%, and 69.5% vs 60.6%, respectively, with no significant differences between the groups (log-rank = 0.011, p = 0.915). Urgent-start PD was associated with fewer short-term dialysis-related complications and similar survival to urgent-start HD in older patients with ESRD. Peritoneal dialysis may thus be a safe and effective dialysis modality for older ESRD patients requiring urgent dialysis. Copyright © 2018 International Society for Peritoneal Dialysis.

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

Purpose: An increased incidence of renal tumors has been observed in patients with end-stage-renal-disease (ESRD). The very strong association with acquired renal cystic disease (ACRD) and increased incidence of the renal tumors (conventional renal cell carcinoma (CRCC), papillary renal cell carcinoma (PRCC) or papillary renal cell adenoma (PRCA)) was reported. This study discusses the role of computed tomography (CT) in detecting renal tumors in patients with renal impairment: pre-dialysis, those receiving dialysis or with renal allograft transplants. Materials and methods: Ten patients (nine male, one female) with renal cell tumors were enrolled into a retrospective study; two were new dialysis patients, three on long-term dialysis, and five were renal transplant recipients with history of dialysis. All patients underwent helical CT, a total of 11 procedures were performed. Sixteen-row detector system was used five times, and a 64-row detector system for the six examinations. All patients underwent nephrectomy of kidney with suspected tumor, 15 nephrectomies were performed, and 1 kidney was assessed during autopsy. CT findings were compared with macroscopic and microscopic assessments of the kidney specimen in 16 cases. Results: Very advanced renal parenchyma atrophy with small cysts corresponding to ESRD was found in nine patients, chronic pyelonephritis in remained one. A spontaneously ruptured tumor was detected incidentally in one case, patient died 2 years later. In the present study, 6.25% (1/16) were multiple PRCA, 12.5% (2/16) were solitary PRCC, 12.5% tumors (2/16) were solitary conventional renal cell carcinomas (CRCC's), 12.5% tumors (2/16) were multiple conventional renal cell carcinomas (CRCC's), 25% (4/16) were CRCC's combined with multiple papillary renal cell carcinomas with adenomas (PRCC's and PRCA's), and 25% (4/16) of the tumors were multiple PRCC's combined with PRCA's without coexisting CRCC's. Bilateral renal tumors were found in our study

Myths in peritoneal dialysis.

To clarify misconceptions about the feasibility and risks of peritoneal dialysis that unnecessarily limit peritoneal dialysis uptake or continuation in patients for whom peritoneal dialysis is the preferred dialysis modality. The inappropriate choice of haemodialysis as a result of these misconceptions contributes to low peritoneal dialysis penetrance, increases transfer from peritoneal dialysis to haemodialysis, increases expenditure on haemodialysis and compromises quality of life for these patients. Peritoneal dialysis is an excellent renal replacement modality that is simple, cost-effective and provides comparable clinical outcomes to conventional in-centre haemodialysis. Unfortunately, many patients are deemed unsuitable to start or continue peritoneal dialysis because of false or inaccurate beliefs about peritoneal dialysis. Here, we examine some of these 'myths' and critically review the evidence for and against each of them. We review the feasibility and risk of peritoneal dialysis in patients with prior surgery, ostomies, obesity and mesh hernia repairs. We examine the fear of mediastinitis with peritoneal dialysis after coronary artery bypass graft surgery and the belief that the use of hypertonic glucose dialysate causes peritoneal membrane failure. By clarifying common myths about peritoneal dialysis, we hope to reduce overly cautious practices surrounding this therapy.

Cardiovascular morbidity and mortality are common in end stage renal disease (ESRD) patients. There is scarce data on carotid and bulb intima-media thickness (IMT-C and IMT-B) as an early marker of atherosclerosis and related factors in children on hemodialysis (HD) and peritoneal dialysis (PD). Since we did not have enough information about our patients, this study was carried on all ESRD children (hemodialysis and peritoneal dialysis) in a referral center. Data was collected from 16 ESRD children under 18 years with seven patients on PD and nine on HD. Lab tests and biochemical parameters including serum von Willebrand factor (vWF), homocystein, apo lipoprotein A, apo lipoprotein B and quantitative CRP were measured in fasting patients just before initiating dialysis. IMT-C and IMT-B were measured by gray scale ultrasound using 7.5 MHZ probe. The mean of age was 12.76+/-4.5 years. The mean duration of dialysis in HD and PD patients were not significantly different; 11.88+/-3.25 months and 10.14+/-2.4 months respectively. Mean of systolic blood pressure in HD group was significantly higher than PD group, 135.55+/-25.54 mmHg versus 121.42+/-12.14 mmHg, Phomocystein and IMT-C. However, we could not demonstrate any difference between IMT-B in case and control group. After adjusting for age, partial correlation showed significant correlation between IMT-C and following factors: N-PTH and serum alkaline phosphatase. Longitudinal studies with large size samples are needed to clarify the contributing factors with intima-media thickness in ESRD children.

Peritoneal dialysis in the neonatal intensive care unit. Management of acute renal failure after a severe subgaleal hemorrhage.

Acute renal failure is common in the neonatal intensive care unit but is often not recognized in its early phases, when it is potentially reversible. The typical patient with acute renal failure is premature, but many term infants are also at risk. One such group is those with severe bleeding, such as a subgaleal hemorrhage. In these cases, hypovolemia can quickly progress to ischemia, which affects many organs but has profound effects on the kidney. In term infants, acute renal failure is most commonly diagnosed in those with perinatal depression. This article presents a unique case of an infant with subgaleal and intracranial bleeding that resulted in acute renal failure requiring peritoneal dialysis in the hopes of the eventual restoration of kidney function.

Readmissions following hospital discharge among maintenance dialysis patients are common, potentially modifiable, and costly. Compared with patients receiving in-center hemodialysis (HD), patients receiving peritoneal dialysis (PD) have fewer routine dialysis clinic encounters and as a result may be more susceptible to a hospital readmission following discharge. Population-based retrospective-cohort observational study. Patients treated with maintenance dialysis who were discharged following an acute-care hospitalization during January 1, 2003, to December 31, 2013, across 164 acute-care hospitals in Ontario, Canada. For those with multiple hospitalizations, we randomly selected a single hospitalization as the index hospitalization. Dialysis modality PD or in-center HD. Propensity scores were used to match each patient on PD therapy to 2 patients on in-center HD therapy to ensure that baseline indicators of health were similar between the 2 groups. All-cause 30-day readmission following the index hospital discharge. 28,026 dialysis patients were included in the study. 4,013 PD patients were matched to 8,026 in-center HD patients. Among the matched cohort, 30-day readmission rates were 7.1 (95% CI, 6.6-7.6) per 1,000 person-days for patients on PD therapy and 6.0 (95% CI, 5.7-6.3) per 1,000 person-days for patients on in-center HD therapy. The risk for a 30-day readmission among patients on PD therapy was higher compared with those on in-center HD therapy (adjusted HR, 1.19; 95% CI, 1.08-1.31). The primary results were consistent across several key prespecified subgroups. Lack of information for the frequency of nephrology physician encounters following discharge from the hospital in both the PD and in-center HD cohorts. Limited validation of International Classification of Diseases, Tenth Revision codes. The risk for 30-day readmission is higher for patients on home-based PD compared to in-center HD therapy.

Dialysis access should be timely, minimise complications and maintain functionality. Good functional access is required for renal replacement therapy (RRT) to be successful. The aim of the combined vascular and peritoneal dialysis access audit was to examine practice patterns with respect to dialysis access and highlight variations in practice between renal centres. The UK Renal Registry collected centre-specific information on vascular and peritoneal access outcome measures including patient demographics, dialysis access type (at start of dialysis and three months after start of dialysis), surgical assessment and access functionality. The combined access audit covered incident haemodialysis (HD) and peritoneal dialysis (PD) patients in 2012 from England, Northern Ireland and Wales. Centres who had reported data on incident PD patients for the previous audit in 2011 were additionally asked to provide one year follow up data for this group. Fifty-one centres in England, Wales and Northern Ireland (representing 82% of all centres) returned data on first access from 3,720 incident HD patients and 1,018 incident PD patients. A strong relationship was seen between surgical assessment and the likelihood of starting HD with an arteriovenous fistula (AVF). Type of first access was related to the length of time known to renal services with higher numbers of AVFs and PD catheters used in patients known to renal services for at least one year. Three month and one year outcomes of HD and PD access were poorly reported. This audit provides information on important patient related outcome measures with the potential to lead to an improvement in access provision. This represents an important advance, however data collection remains suboptimal. There is wide practice variation across the England, Wales and Northern Ireland in provision of both HD and PD access which requires further exploration. © 2014 S. Karger AG, Basel.

The aims were: to assess the kinetics of 99m-technetium MBP (99mTc-MBP) in CAPD, and to evaluate the correctness of the assumption that the peritoneal and renal clearances of 99mTc-MBP equal the total plasma clearance of 51-chromium ethylenediamine tetra......Tc-MBP equal the clearances of 51Cr-EDTA is correct from a clinical point of view. We found that the uptake of the tracers in soft tissue and the renal handling of 51Cr-EDTA and 99mTc-MBP are also similar.

Experience in the use of continuous ambulatory peritoneal dialysis (CAPD) for the treatment of end stage renal failure in Nottingham was reviewed. During six years 150 patients aged from 11 to 73 received this type of treatment. At three years patient actuarial survival was 69% and CAPD technique survival was 41%. Although CAPD was satisfactory as a first treatment for many patients, its long term use was possible in only a few. Actuarial survival of patients who changed to haemodialysis was 64% at one year after the change, suggesting that unsuccessful CAPD increased the risk of death. Hospital haemodialysis was the only suitable form of treatment for most patients in whom CAPD had been abandoned. British renal units have adopted CAPD to a much greater extent than those in Europe, but care in the selection of patients is necessary to reduce mortality, and many patients may eventually need hospital haemodialysis. Greater numbers of hospital haemodialysis places will probably have to be made available to meet this extra demand.

The prevalence of childhood overweight is rising worldwide, but in children on renal replacement therapy (RRT) a poor nutritional status is still the primary concern. We aimed to study the prevalence of, and factors associated with, underweight and overweight/obesity in the European paediatric RRT population. Moreover, we assessed the evolution of body mass index (BMI) after the start of RRT. We included 4474 patients younger than 16 years from 25 countries of whom BMI data, obtained between 1995 and 2010, were available within the European Society for Paediatric Nephrology/European Renal Association-European Dialysis and Transplant Association Registry. Prevalence estimates for under- and overweight/obesity were calculated using age and sex-specific criteria of the World Health Organization (WHO, 0-1 year olds) and the International Obesity Task Force cut-offs (2-15 year olds). The prevalence of underweight was 3.5%, whereas 20.8% of the patients were overweight and 12.5% obese. Factors associated with being underweight were receiving dialysis treatment and infant age. Among transplanted recipients, a very short stature (OR: 1.64, 95% CI: 1.40-1.92) and glucocorticoid treatment (OR: 1.23, 95% CI: 1.03-1.47) were associated with a higher risk of being overweight/obese. BMI increased post-transplant, and a lower BMI and a higher age at the start of RRT were associated with greater BMI changes during RRT treatment. Overweight and obesity, rather than underweight, are highly prevalent in European children on RRT. Short stature among graft recipients had a strong association with overweight, while underweight appears to be only a problem in infants. Our findings suggest that nutritional management in children receiving RRT should focus as much on the prevention and treatment of overweight as on preventing malnutrition.

The French Renal Epidemiology and Information Network (REIN) registry began in 2002 to provide a tool for public health decision support, evaluation and research related to renal replacement therapies (RRT) for end-stage renal disease (ESRD). It is relying on a network of nephrologists, epidemiologists, patients and public health representatives. Continuous registration covers all dialysis and transplanted patients. In 2012, in France, 10,048 patients started a RRT (154 per million inhabitants). Elders provided majority of new patients (median age at RRT start: 70 years old). New patients had a high and age increasing rate of comorbidities, especially diabetes (42% of the new patients) and cardiovascular comorbidities (>50% of the new patients). Like previous years, incidence is stabilized. On December 31, 2012, 73,491 patients were receiving a RRT in France (1127 per million inhabitants, 56% on dialysis and 44% living with a functional renal transplant). More than 50% of patients were undergoing in-center hemodialysis with significant variations among regions. An increase in medical satellite unit hemodialysis but a decrease in self-care unit hemodialysis rates were noticed across the time, whereas peritoneal dialysis remained stable at 7%. Five years after starting RRT, the overall survival rate was 51% but only 16% among patients over 85 years. Mortality rate was highly dependent on treatment and age; transplanted patients aged 60-69 had a 27/1000 patients-year mortality rate versus 133 for a dialysis patient. Patients who started dialysis had a probability of first wait-listing of 4.8% at the start of dialysis (pre-emptive registrations) and 27% at 72 months. Whatever their diabetes status was, patients older than 60 had poor access to the waiting list. Seventeen percent of the patients received a first renal transplant within 15.4 month median time; 3% had received a pre-emptive graft. Ten years after the start of the French ESRD registry, this report provides

Full Text Available Sleep apnea (SA and excessive daytime sleepiness (EDS are common sleep disorders among patients with end-stage renal disease (ESRD. This cross-sectional study, carried out in two dialysis centers in Saudi Arabia, assessed the prevalence of sleep apnea and sleepiness in Saudi patients with ESRD who are on maintenance dialysis with either peritoneal or hemodialysis. We used questionnaires to assess the prevalence of SA and EDS. The association between sleep apnea, EDS, and other sleep disorders, the underlying causes of renal failure, and other demo-graphic data were also examined. Among 227 enrolled patients, the mean patient age was 55.7 years ΁ 17.2 years; 53.7% were male, and 46.3% were female. The overall prevalence of SA as defined by the Berlin questionnaire (BQ was 37% in males and 34% in females, which was not a statistically significant difference (P = 0.459. Sleep apnea was significantly associated with age, neck size, afternoon and evening hemodialysis shift, obesity, diabetes, and hypertension (P-values, 0.001, 0.029, < 0.0001, < 0.0001, < 0.008, 0.002, and < 0.001, respectively. Sleep apnea was also significantly associated with other sleep disorders such as restless leg syndrome, insomnia, habitual snoring, and EDS (P-values, < 0.001, < 0.001, < 0.001, and < 0.001, respectively. The prevalence of EDS was 44%, and EDS was significantly more prevalent in patients undergoing peritoneal dialysis (P < 0.001; it was also associated with older age, diabetes mellitus, and other sleep disorders. SA and EDS are common in dialysis patients and are significantly associated with other sleep disorders.

Dialysis access should be timely, minimize complications and maintain functionality. The aim of the second combined vascular and peritoneal dialysis access audit was to examine practice patterns with respect to dialysis access and highlight variations in practice between renal centres. The UK Renal Registry collected centre-specific information on incident vascular and peritoneal dialysis access outcome measures in patients from England, Wales and Northern Ireland (EW&NI), including patient demographics, dialysis access type (at start of dialysis and three months after start of dialysis), surgical assessment and access functionality. Centres who had reported data on incident PD patients for the previous 2012 audit were additionally asked to provide one year follow up data for this group. The findings were compared to the audit measures stated in Renal Association clinical practice guidelines for dialysis access. Fifty-seven centres in EW&NI (representing 92% of all centres) returned data on first access from 3,663 incident HD patients and 1,022 incident PD patients. A strong relationship was seen between surgical assessment and the likelihood of starting HD with an arteriovenous fistula (AVF). Twenty-four centres were at least two standard deviations below the 65% target for incident patients starting haemodialysis on AVF and only eight centres (14%) were within two standard deviations of the 85% target for prevalent haemodialysis patients on AVF. There was wide practice variation across the UK in provision of both HD and PD access which requires further exploration.

Peritoneal Dialysis in Asia.

There is a growing demand of dialysis in Asia for end-stage renal failure patients. Diabetes mellitus is the leading cause of end-stage renal failure in many countries in Asia. The growth of peritoneal dialysis (PD) in Asia is significant and seeing a good trend. With the enhanced practices of PD, the quality of care in PD in Asia is also improved. Overall, PD and hemodialysis (HD) are comparable in clinical outcome. There is a global trend in the reduction of peritonitis rates and Asian countries also witness such improvement. The socio-economic benefits of PD for end-stage renal failure patients in both urban and rural areas in the developed and developing regions of Asia are an important consideration. This can help to reduce the financial burden of renal failure in addressing the growing demand of patients on dialysis. Initiatives should be considered to further drive down the cost of PD in Asia. Growing demand for dialysis by an increasing number of end-stage renal failure patients requires the use of a cost-effective quality dialysis modality. PD is found to be comparable to HD in outcome and quality. In most countries in Asia, PD should be more cost-effective than HD. A 'PD-first' or a 'PD as first considered therapy' policy can be an overall strategy in many countries in Asia in managing renal failure patients, taking the examples of Hong Kong and Thailand. (1) PD is cheaper than HD and provides a better quality of life worldwide, but its prevalence is significantly lower than that of HD in all countries, with the exception of Hong Kong. Allowing reimbursement of PD but not HD has permitted to increase the use of PD over HD in many Asian countries like Hong Kong, Vietnam, Taiwan, Thailand, as well as in New Zealand and Australia over the last years. In the Western world, however, HD is still promoted, and the proportion of patients treated with PD decreases. Japan remains an exception in Asia where PD penetration is very low.

Initiating renal replacement therapy in late referred patients with central venous catheter (CVC) hemodialysis (HD) causes serious complications. In urgent start peritoneal dialysis, initiating peritoneal dialysis (PD) within 14 days of catheter insertion still needs HD with CVC. We initiated Emergent start PD (ESPD) with Automated PD (APD) at our center within 48 h from the time of presentation. A prospective, case-controlled, intention-to-treat study with 56 patients was conducted between March 2016 and August 2017. Group A (24 patients) underwent conventional PD 14 days after catheter insertion. Group B (32 patients), underwent ESPD with APD. Exit site leak (ESL), catheter blockage, and peritonitis at 90 days were primary outcomes. Technique survival was secondary outcome. Baseline characteristics were similar with 3 episodes of ESLs (9.4%) in the study group and none in the control group (p = 0.123). Catheter blockage (16.7%-Group A, 25%-Group B) and peritonitis (none vs. 9.4% in study group) were similar in terms of statistical details just as technique survival (95%-Group A, 88.2%-Group B at 90 days). ESPD with APD in the unplanned patient is an appropriate approach. © 2018 S. Karger AG, Basel.

Abstract Background: This article summarizes the European Renal Association – European Dialysis and Transplant Association Registry’s 2014 annual report. It describes the epidemiology of renal replacement therapy (RRT) for end-stage renal disease (ESRD) in 2014 within 35 countries. Methods: In 2016, the ERA-EDTA Registry received data on patients who in 2014 where undergoing RRT for ESRD, from 51 national or regional renal registries. Thirty-two registries provided individual patient level data and 19 provided aggregated patient level data. The incidence, prevalence and survival probabilities of these patients were determined. Results: In 2014, 70 953 individuals commenced RRT for ESRD, equating to an overall unadjusted incidence rate of 133 per million population (pmp). The incidence ranged by 10-fold; from 23 pmp in the Ukraine to 237 pmp in Portugal. Of the patients commencing RRT, almost two-thirds were men, over half were aged ≥65 years and a quarter had diabetes mellitus as their primary renal diagnosis. By day 91 of commencing RRT, 81% of patients were receiving haemodialysis. On 31 December 2014, 490 743 individuals were receiving RRT for ESRD, equating to an unadjusted prevalence of 924 pmp. This ranged throughout Europe by more than 10-fold, from 157 pmp in the Ukraine to 1794 pmp in Portugal. In 2014, 19 406 kidney transplantations were performed, equating to an overall unadjusted transplant rate of 36 pmp. Again this varied considerably throughout Europe. For patients commencing RRT during 2005–09, the 5-year-adjusted patient survival probabilities on all RRT modalities was 63.3% (95% confidence interval 63.0–63.6). The expected remaining lifetime of a 20- to 24-year-old patient with ESRD receiving dialysis or living with a kidney transplant was 21.9 and 44.0 years, respectively. This was substantially lower than the 61.8 years of expected remaining lifetime of a 20-year-old patient without ESRD. PMID:28584624

To explore decisional conflict and its influencing factors on choosing dialysis modality in patients with end-stage renal diseases. The influencing factors investigated include demographics, predialysis education, dialysis knowledge, decision self-efficacy and social support. Making dialysis modality decisions can be challenging for patients with end-stage renal diseases; there are pros and cons to both haemodialysis and peritoneal dialysis. Patients are often uncertain as to which one will be the best alternative for them. This decisional conflict increases the likelihood of making a decision that is not based on the patient's values or preferences and may result in undesirable postdecisional consequences. Addressing factors predisposing patients to decisional conflict helps to facilitate informed decision-making and then to improve healthcare quality. A predictive correlational cross-sectional study design was used. Seventy patients were recruited from the outpatient dialysis clinics of two general hospitals in Taiwan. Data were collected with study questionnaires, including questions on demographics, dialysis modality and predialysis education, the Dialysis Knowledge Scale, the Decision Self-Efficacy scale, the Social Support Scale, and the Decisional Conflict Scale. The mean score on the Decisional Conflict Scale was 29.26 (SD = 22.18). Decision self-efficacy, dialysis modality, predialysis education, professional support and dialysis knowledge together explained 76.4% of the variance in decisional conflict. Individuals who had lower decision self-efficacy, did not receive predialysis education on both haemodialysis and peritoneal dialysis, had lower dialysis knowledge and perceived lower professional support reported higher decisional conflict on choosing dialysis modality. When providing decisional support to predialysis stage patients, practitioners need to increase patients' decision self-efficacy, provide both haemodialysis and peritoneal dialysis

Peritoneal dialysis-related peritonitis: challenges and solutions

Science.gov (United States)

Salzer, William L

2018-01-01

Peritoneal dialysis is an effective treatment modality for patients with end-stage renal disease. The relative use of peritoneal dialysis versus hemodialysis varies widely by country. Data from a 2004 survey reports the percentage of patients with end-stage renal disease treated with peritoneal dialysis to be 5%–10% in economically developed regions like the US and Western Europe to as much as 75% in Mexico. This disparity is probably related to the availability and access to hemodialysis, or in some cases patient preference for peritoneal over hemodialysis. Peritoneal dialysis-related peritonitis remains the major complication and primary challenge to the long-term success of peritoneal dialysis. Fifty years ago, with the advent of the Tenckhoff catheter, patients averaged six episodes of peritonitis per year on peritoneal dialysis. In 2016, the International Society for Peritoneal Dialysis proposed a benchmark of 0.5 episodes of peritonitis per year or one episode every 2 years. Despite the marked reduction in peritonitis over time, peritonitis for the individual patient is problematic. The mortality for an episode of peritonitis is 5% and is a cofactor for mortality in another 16% of affected patients. Prevention of peritonitis and prompt and appropriate management of peritonitis is essential for the long-term success of peritoneal dialysis in all patients. In this review, challenges and solutions are addressed regarding the pathogenesis, clinical features, diagnosis, treatment, and prevention of peritoneal dialysis-related peritonitis from the viewpoint of an infectious disease physician.

Commencement of haemodialysis with an arteriovenous fistula (AVF) or arteriovenous graft (AVG) is associated with improved survival compared with commencement with a central venous catheter. In 2011-2012, Queensland Health made incentive payments to renal units for early referred patients who commenced peritoneal dialysis (PD), or haemodialysis with an AVF/AVG. The aim of this study was to determine if pay for performance improved clinical care. All patients who commenced dialysis in Australia between 2009 and 2014 and were registered with the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) were included. A multivariable regression model was used to compare rates of commencing dialysis with a PD catheter or permanent AVF/AVG during the pay-for-performance period (2011-2012) with periods prior (2009-2010) and after (2013-2014). A total of 10 858 early referred patients commenced dialysis during the study period, including 2058 in Queensland. In Queensland, PD as first modality increased with time (P pay-for-performance period as reference, the odds ratio for commencement with PD or haemodialysis with an AVF/AVG in Queensland was 1.02 (95% CI 0.81-1.29) in 2009-2010 and 1.28 (95% CI 1.01-1.61) in 2013-2014. There was no change for the rest of Australia (0.97 95% CI 0.87-1.09 in 2009-2010 and 1.00 95% CI 0.90-1.11 in 2013-14). Pay for performance did not improve rates of commencement of dialysis with PD or an AVF/AVG during the payment period. A lag effect on clinical care may explain the improvement in later years. © 2017 Asian Pacific Society of Nephrology.

Being-in-dialysis: The experience of the machine-body for home dialysis users.

New Zealand leads the world in rates of home dialysis use, yet little is known about the experience of home dialysis from the patient's perspective. This article contributes to the literature on the self-care of dialysis patients by examining the relevance of the concept of the machine-body and cyborg embodiment for the lived experience of people with end-stage renal failure. The article, which presents a discussion of 24 in-depth interviews undertaken between 2009 and 2012, shows that although dialysis therapy is disruptive of being and time, study participants experience home dialysis in terms of flexibility, control and independence. While they do not use the term machine-body as a descriptor, the concept resonates with felt experience. Data also indicate that positive experience of home dialysis is relative to socio-economic positioning and the lived relation of patients to others, necessitating further research to examine these factors. © The Author(s) 2014.

Effects of Cholesterol Levels on Mortality in Patients with Long-Term Peritoneal Dialysis Based on Residual Renal Function

Full Text Available The effect of dyslipidemia on peritoneal dialysis (PD patients based on the presence of residual renal function (RRF; renal creatinine clearance >2 mL/min/1.73 m2 is unknown. Data from the Taiwan Renal Registry Data System between 2005 and 2012 were analyzed to estimate the association between dyslipidemia and mortality in PD patients. Long-term PD patients (n = 8032 were divided into groups with (RRF; n = 2691, 33.5% and without RRF (non-RRF; n = 5341, 66.5%. The primary outcome was three-year mortality, and multivariate Cox regression was used for survival analysis. After stratifying the total cholesterol (TC level between the first and third years, the hazard ratio for mortality was estimated. In the non-RRF group, TC < 120 mg/dL was associated with independently increased risk of mortality. In the RRF group, low TC was not independently correlated with increased mortality, but TC > 285 mg/dL was associated with increased risk. PD patients with higher level of TC (>200 mg/dL in both first and third years of dialysis had significantly lower risk of mortality. In this nationwide cohort study, PD patients without RRF who had low TC level had the highest mortality, in contrast to those with RRF. Malnutrition in long-term PD patients without RRF is an important issue to be monitored.

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

Nutrition and the dialysis prescription.

Malnutrition is common among patients with acute and chronic renal failure. The efficiency of modern dialytic techniques has allowed for more liberal administration of nutrients to patients with renal failure, particularly with regard to protein and amino acids. Protein restriction is not indicated for patients on dialysis, and should be employed cautiously, if at all, in patients with renal insufficiency. The 'nutrition prescription' should be considered a vital part of the comprehensive medical, surgical, and dialytic care provided to patients with renal disease.

Recent studies reported that early initiation of hemodialysis may increase mortality. However, studies that assessed the influence of early initiation of peritoneal dialysis (PD) yielded controversial results. In the present study, we evaluated the prognosis of early initiation of PD on the various outcomes of end stage renal failure patients by using propensity-score matching methods. Incident PD patients (n = 491) who started PD at SNU Hospital were enrolled. The patients were divided into 'early starters (n = 244)' and 'late starters (n = 247)' on the basis of the estimated glomerular filtration rate (eGFR) at the start of dialysis. The calculated propensity-score was used for one-to-one matching. After propensity-score-based matching (n = 136, for each group), no significant differences were observed in terms of all-cause mortality (P = 0.17), technique failure (P = 0.62), cardiovascular event (P = 0.96) and composite event (P = 0.86) between the early and late starters. Stratification analysis in the propensity-score quartiles (n = 491) exhibited no trend toward better or poorer survival in terms of all-cause mortality. In conclusion, early commencement of PD does not reduce the mortality risk and other outcomes. Although the recent guidelines suggest that initiation of dialysis at higher eGFR, physicians should not determine the time to initiate PD therapy simply rely on the eGFR alone. PMID:22323864

Optimizing home dialysis: role of hemodiafiltration.

Over the last 40 years the technical obstacles which prevented a convective contribution to diffusive dialysis have been overcome. Hemodiafiltration represents a natural evolution of intermittent extracorporeal blood purification and the technology is now available to offer this as standard treatment in-center. The first randomized control trial of dialysis dose (National Cooperative Dialysis Study) showed that for three times weekly dialysis a critical level of urea clearance was necessary to ensure complication-free survival, the effect being noticeable by 3 months. Following this, observational studies suggested that higher doses improved longer term outcome. In a second large randomized controlled study (HEMO), higher small molecule clearance did not further improve outcome, but high-flux membranes, which permitted enhanced clearance of middle molecules, appeared to confer survival benefit in patients who had already been on dialysis > 3.7 years. Recently, outcomes from the Membrane Permeability Outcome study confirmed a survival benefit of high-flux membranes in high-risk patients. These studies indicate that in the medium term survival is critically dependent on achieving a minimum level of small solute removal. However, longer term survival (measured in years or decades) not only requires better small solute clearance but also enhanced clearance of middle molecules, the toxicity of which manifest over longer time scales. The rationale for convective treatment is strongest, therefore in those patients who have the greatest potential for long-term survival. Patients who opt for self-care at home to allow frequent dialysis generally are constituents of this group. Hemodiafiltration is likely to become standard therapy in-center and in the home.

Full Text Available Agents targeting the vascular endothelial growth factor (VEGF/VEGF receptor (VEGFR pathway, as well as mammalian target of rapamycin (mTOR inhibitors have revolutionised the therapeutic landscape of metastatic renal cell carcinoma (mRCC in the past decade, greatly improving the survival rates of these patients. However, translating results of registrative Phase III trials into everyday clinical practice is often troublesome, since real-world patients are completely different from those enrolled in randomised controlled Phase III trials. Prospective data on active oncological treatments in mRCC patients on dialysis are dramatically lacking. This literature review summarises and critically comments on available data relative to mRCC patients on dialysis receiving either VEGF/VEGFR-targeting agents, or mTOR inhibitors. Although prospective studies would definitely be warranted in these specific patient populations, all the available data suggest that mRCC patients on dialysis have the same outcome, both in terms of efficacy and safety, as mRCC patients with normal or marginally impaired kidney function, when treated with VEGF/VEGFR-targeting agents and/or mTOR inhibitors.

Full Text Available Studies comparing patient survival of hemodialysis (HD and peritoneal dialysis (PD have yielded conflicting results and no such study was from South-East Asia. This study aimed to compare the survival outcomes of patients with end-stage renal disease (ESRD who started dialysis with HD and PD in Singapore.Survival data for a maximum of 5 years from a single-center cohort of 871 ESRD patients starting dialysis with HD (n = 641 or PD (n = 230 from 2005-2010 was analyzed using the flexible Royston-Parmar (RP model. The model was also applied to a subsample of 225 propensity-score-matched patient pairs and subgroups defined by age, diabetes mellitus, and cardiovascular disease.After adjusting for the effect of socio-demographic and clinical characteristics, the risk of death was higher in patients initiating dialysis with PD than those initiating dialysis with HD (hazard ratio [HR]: 2.08; 95% confidence interval [CI]: 1.67-2.59; p<0.001, although there was no significant difference in mortality between the two modalities in the first 12 months of treatment. Consistently, in the matched subsample, patients starting PD had a higher risk of death than those starting HD (HR: 1.73, 95% CI: 1.30-2.28, p<0.001. Subgroup analysis showed that PD may be similar to or better than HD in survival outcomes among young patients (≤65 years old without diabetes or cardiovascular disease.ESRD patients who initiated dialysis with HD experienced better survival outcomes than those who initiated dialysis with PD in Singapore, although survival outcomes may not differ between the two dialysis modalities in young and healthier patients. These findings are potentially confounded by selection bias, as patients were not randomized to the two dialysis modalities in this cohort study.

These deposits may result in a wide range of clinical manifestations depending upon their type, location, and the amount of deposition. Dialysis-related amyloidosis is a serious complication of long-term dialysis therapy and is characterized by the deposition of amyloid fibrils, principally composed of β2 microglobulins (β2M, in the osteoarticular structures and viscera. Most of the β2M is eliminated through glomerular filtration and subsequent reabsorption and catabolism by the proximal tubules. As a consequence, the serum levels of β2M are inversely related to the glomerular filtration rate; therefore, in end-stage renal disease patients, β2M levels increase up to 60-fold. Serum levels of β2M are also elevated in several pathological conditions such as chronic inflammation, liver disease, and above all, in renal dysfunction. Retention of amyloidogenic protein has been attributed to several factors including type of dialysis membrane, prolonged uremic state and/or decreased diuresis, advanced glycation end products, elevated levels of cytokines and dialysate. Dialysis treatment per se has been considered to be an inflammatory stimulus, inducing cytokine production (such as interleukin-1, tumor necrosis factor-α, interleukin-6 and complement activation. The released cytokines are thought to stimulate the synthesis and release of β2M by the macrophages and/or augment the expression of human leukocyte antigens (class I, increasing β2M expression. Residual renal function is probably the best determinant of β2M levels. Therefore, it has to be maintained as long as possible. In this article

Full Text Available Background Multiple myeloma (MM is a haematological malignancy associated with kidney injury resulting from cast nephropathy, which can be caused by monoclonal free light chains (FLC. It has been demonstrated that reduction of FLC can lead to a higher proportion of patients recovering renal function with a better outcome, especially if extended high cut-off haemodialysis (HCO-HD combined with chemotherapy is used. Patients and Methods In this study, four cases of MM nephropathy were treated with HCO-HD and chemotherapy at a single institution during the period from August 2009 to August 2011. All of the patients presented with acute renal failure and high serum FLC. All patients underwent a bone marrow biopsy to confirm the diagnosis of MM, according to the WHO criteria. Three patients had de-novo MM and one patient had relapsed light chain myeloma disease. All patients underwent HCO-HD concomitantly with specific myeloma therapy once the diagnosis or relapse of MM was established. Results After a median follow up of 26 months, (range, 13-36 our data showed that all patients had a significant decrease in serum FLC through HCO-HD, proving the effectiveness of HCO-HD in managing MM. De-novo MM patients restored their renal function and achieved low-level FLC early on the treatment and become dialysis-independent. One patient with relapsed myeloma remained dialysis dependant. Conclusion Our study suggests that if myeloma nephropathy associated with light-chain disease, HCO-HD should be initiated as early as possible. At the same time a specific MM treatment should be initiated to gain control of the disease and salvage the kidneys in order to achieve dialysis-independency. Further trials to confirm our results are warranted. Key Words: Multiple myeloma, renal failure, High cut-off haemodialysis, chemotherapy, outcome.

Healthcare reimbursement is increasingly tied to value instead of volume, with special attention paid to resource-intensive populations such as patients with renal disease. To this end, Medicare has sponsored pilot projects to encourage providers to develop care coordination and population health management strategies to provide quality care while reducing resource utilization. In this Personal Viewpoint essay, we argue in favor of expanding one such pilot project-the Comprehensive ESRD Care (CEC) initiative-to include patients with advanced chronic kidney disease and kidney transplant recipients. The implementation of the Medicare Access and CHIP Reauthorization Act (MACRA) offers a time-sensitive incentive for transplant centers in particular to align with extant CECs. An "expanded" CEC model proffers opportunity for robust cooperation between general nephrology practices, dialysis providers, and transplant centers to develop care coordination strategies for all patients with renal disease, realign incentives for all clinical stakeholders to increase kidney transplantation rates, and reduce total costs of care. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

Disruptive technological advances in vascular access for dialysis: an overview.

End-stage kidney disease (ESKD), one of the most prevalent diseases in the world and with increasing incidence, is associated with significant morbidity and mortality. Current available modes of renal replacement therapy (RRT) include dialysis and renal transplantation. Though renal transplantation is the preferred and ideal mode of RRT, this modality may not be available to all patients with ESKD. Moreover, renal transplant recipients are constantly at risk of complications associated with immunosuppression and immunosuppressant use, and posttransplant lymphoproliferative disorder. Dialysis may be the only available modality in certain patients. However, dialysis has its limitations, which include issues associated with lack of vascular access, risks of infections and vascular thrombosis, decreased quality of life, and absence of biosynthetic functions of the kidney. In particular, the creation and maintenance of hemodialysis vascular access in children poses a unique set of challenges to the pediatric nephrologist owing to the smaller vessel diameters and vascular hyperreactivity compared with adult patients. Vascular access issues continue to be one of the major limiting factors prohibiting the delivery of adequate dialysis in ESKD patients and is the Achilles' heel of hemodialysis. This review aims to provide a critical overview of disruptive technological advances and innovations for vascular access. Novel strategies in preventing neointimal hyperplasia, novel bioengineered products, grafts and devices for vascular access will be discussed. The potential impact of these solutions on improving the morbidity encountered by dialysis patients will also be examined.

End-stage kidney disease (ESKD) is one of the most prevalent diseases in the world with significant morbidity and mortality. Current modes of renal replacement therapy include dialysis and renal transplantation. Although dialysis is an acceptable mode of renal replacement therapy, it does have its shortcomings, which include poorer life expectancy compared with renal transplantation, risk of infections and vascular thrombosis, lack of vascular access and absence of biosynthetic functions of the kidney. Renal transplantation, in contrast, is the preferred option of renal replacement therapy, with improved morbidity and mortality rates and quality of life, compared with dialysis. Renal transplantation, however, may not be available to all patients with ESKD. Some of the key factors limiting the availability and efficiency of renal transplantation include shortage of donor organs and the constant risk of rejection with complications associated with over-immunosuppression respectively. This review focuses chiefly on the potential roles of bioengineering in overcoming limitations in renal transplantation via the development of cell-based bioartificial dialysis devices as bridging options before renal transplantation, and the development of new sources of organs utilizing cell and organ engineering.

Continuous ambulatory peritoneal dialysis (CAPD) is an alternative to the hemodialysis mode of terminal renal failure treatment. Nutritional status impairment is common among patients with end-stage renal disease, and its laboratory surrogates predict increased morbidity and mortality risk in patients on chronic haemodialysis or peritoneal dialyses. The aetiology of malnutrition is multifactorial and delayed gastric emptying is also considered to be a significant factor. The aim of this study was to estimate the direct influence of indwelled dialysate in the peritoneal cavity on gastric emptying in patients treated with CAPD. The study group included 20 patients (9 males, 11 females) aged 50,1 ± 11 years (range: 39-75 years) with chronic renal failure treated with CAPD for 18.4 ± 14.7 months. All patients were non-diabetic and had no other than chronic uraemia co-morbidity known to influence autonomic nervous system function and gastric motility. The control group included 15 healthy volunteers matched by age, sex and body weight. Dialysis adequacy parameters were calculated based on 24-hour urine and dialysate collections. Gastric emptying was estimated with dynamic abdominal scintigraphy. We compared the results of gastric emptying tests performed in dialysed patients with and without dialysate liquid in the peritoneal cavity and related the values to those of the control subjects. In the study group, weekly values of dialysis parameters were within the ranges considered satisfactory in terms of uraemia control. All parameters of gastric emptying were significantly delayed and prolonged in terminal renal failure patients, but the results have shown no significant differences between those with and without indwelling dialysate. Based on the results we conclude that gastric emptying in subjects with chronic renal failure treated with CAPD is markedly delayed compared to healthy subjects. There was no significant effect of indwelling dialysate in the peritoneal

Renal replacement therapy in sepsis-induced acute renal failure

Full Text Available Acute renal failure (ARF is a common complication of sepsis and carries a high mortality. Renal replacement therapy (RRT during the acute stage is the mainstay of therapy. Va-rious modalities of RRT are available. Continuous RRT using convective methods are preferred in sepsis-induced ARF, especially in hemodynamically unstable patients, although clear evidence of benefit over intermittent hemodialysis is still not available. Peritoneal dialysis is clearly inferior, and is not recommended. Early initiation of RRT is probably advantageous, although the optimal timing of dialysis is yet unknown. Higher doses of RRT are more likely to be beneficial. Use of bio-compatible membranes and bicarbonate buffer in the dialysate are preferred. Anticoagulation during dialysis must be carefully adjusted and monitored.

This rule updates and makes revisions to the End-Stage Renal Disease (ESRD) Prospective Payment System (PPS) for calendar year 2017. It also finalizes policies for coverage and payment for renal dialysis services furnished by an ESRD facility to individuals with acute kidney injury. This rule also sets forth requirements for the ESRD Quality Incentive Program, including the inclusion of new quality measures beginning with payment year (PY) 2020 and provides updates to programmatic policies for the PY 2018 and PY 2019 ESRD QIP. This rule also implements statutory requirements for bid surety bonds and state licensure for the Durable Medical Equipment, Prosthetics, Orthotics, and Supplies (DMEPOS) Competitive Bidding Program (CBP). This rule also expands suppliers' appeal rights in the event of a breach of contract action taken by CMS, by revising the appeals regulation to extend the appeals process to all types of actions taken by CMS for a supplier's breach of contract, rather than limit an appeal for the termination of a competitive bidding contract. The rule also finalizes changes to the methodologies for adjusting fee schedule amounts for DMEPOS using information from CBPs and for submitting bids and establishing single payment amounts under the CBPs for certain groupings of similar items with different features to address price inversions. Final changes also are made to the method for establishing bid limits for items under the DMEPOS CBPs. In addition, this rule summarizes comments on the impacts of coordinating Medicare and Medicaid Durable Medical Equipment for dually eligible beneficiaries. Finally, this rule also summarizes comments received in response to a request for information related to the Comprehensive ESRD Care Model and future payment models affecting renal care.

From the very beginning, the artificial kidney postponed the death of patients with end-stage renal failure. For years, owing to the performance of the machine, the patient was obliged to follow a severe diet in order to maintain good humoral and circulatory status. Now technological improvements allow "dialysis à la carte," whereby each individual achieves a better clinical status. The next step will be automation of the procedure to improve its security, mainly for dialysis performed at home.

The frequency of secondary hyperparathyroidism was 57.4%, corresponding to a total of 62 patients with parathyroid hormone above 300 pg/ml. Parathyroid hormone levels greater than 1000 pg/ml were found in 12.0% (n=13 of the sample.Conclusion: the occurrence of secondary hyperparathyroidism was similar to other retrospective studies published. This data collection can contribute to improve the assistance program for dialysis patients.

A call to arms: economic barriers to optimal dialysis care.

Epidemic growth rates and the enormous cost of dialysis pressure end-stage renal disease (ESRD) delivery systems around the world. Payers of dialysis services can constrain costs through (1) limiting access to dialysis, (2) reducing the quality of dialysis, and (3) placing constraints on modality distribution. In order to secure the necessary resources for ESRD care, we propose that the nephrology community consider the following suggestions: First, future leaders in dialysis should acquire additional advanced training in innovative pathways such as health care economics, business and health care administration, and health care policy. Second, the international nephrology community must strongly engage in ongoing advocacy for accessible, high quality, cost-effective care.Third, efforts should be made to better define and then implement optimal dialysis modality distributions that maximize patient outcomes but limit unnecessary costs. Fourth, industry should be encouraged to lower the unit cost of dialysis, allowing for improved access to dialysis, especially in developing countries. Fifth, research should be encouraged that seeks to identify measures that will reduce dialysis costs but will not impair quality of care. Finally, early referral of patients with progressive renal disease to nephrology clinics, empowerment of informed patient choice of dialysis modality, and proper and timely access creation should be encouraged and can be expected to help limit overall expenditures. Ongoing efforts in these areas by the nephrology community will be essential if we are to overcome the challenges of ESRD growth in this new decade.

End-stage renal disease is a health problem that consumes public and private resources. This study aimed to identify the cost of hemodialysis (either daily or conventional hemodialysis) and transplantation in children and adolescents. This was a retrospective cohort of pediatric patients with End-stage renal disease who underwent hemodialysis followed by kidney transplant. All costs incurred in the treatment were collected and the monthly total cost was calculated per patient and for each renal therapy. Subsequently, a dynamic panel data model was estimated. The study included 30 children who underwent hemodialysis (16 conventional/14 daily hemodialysis) followed by renal transplantation. The mean monthly outlay for hemodialysis was USD 3500 and USD 1900 for transplant. Hemodialysis costs added up to over USD 87,000 in 40 months for conventional dialysis patients and USD 131,000 in 50 months for daily dialysis patients. In turn, transplant costs in 50 months reached USD 48,000 and USD 70,000, for conventional and daily dialysis patients, respectively. For conventional dialysis patients, transplant is less costly when therapy exceeds 16 months, whereas for daily dialysis patients, the threshold is around 13 months. Transplantation is less expensive than dialysis in children, and the estimated thresholds indicate that renal transplant should be the preferred treatment for pediatric patients.

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

Purpose: To evaluate the prevalence of nephrogenic systemic fibrosis (NSF) in a patient population being at highest risk for developing this disease and to evaluate possible risk factors. Materials and methods: The radiological records of 552 patients with ESRD being on hemodialysis (HD) or peritoneal dialysis (PD) were retrospectively reviewed to identify whether the patients underwent MR-examinations with or without intravenous administration of GBCA. In case of exposure to GBCA, the number of contrast injections, the benchmark and the cumulative doses of GBCA, and possible cofactors regarding pathogenesis of NSF were recorded. Diagnosis of NSF was confirmed either by deep skin biopsy or by review of medical and histopathological records. Data of NSF patients were compared with data of dialysis patients who did not develop NSF after MR-examinations. Results: 146 dialysis patients underwent MRI without i.v.-administration of GBCA. No case of NSF was observed in this patient population. 195/552 patients proved to have a total number of 325 well-documented exposures to GBCA. Seven different types of GBCA were used during these MR-examinations. NSF prevalence rate was 1.6%. One patient died of NSF. Three different types of GBCA were involved in 6 NSF cases. 4/6 proved to be confounded cases. The cumulative dose of GBCA, history of thrombosis, recent surgery, and the combination of HD and PD proved to be significant cofactors for the development of NSF (p < .05). No significant difference regarding residual renal clearance (p = .898) and residual urine volume (p = .083) was found between NSF and non-NSF patients. Conclusion: The prevalence of NSF proved to be much lower in this high risk patient group being exposed to GBCA compared to the literature. NSF was not observed in ESRD patients undergoing MRI without administration of GBCA. Our data support a positive association between cumulative dose of GBCA and development of NSF. No positive association was found

to continuous ambulatory peritoneal dialysis (CAPD). The aims were: to assess the kinetics of 99m-technetium MBP (99mTc-MBP) in CAPD, and to evaluate the correctness of the assumption that the peritoneal and renal clearances of 99mTc-MBP equal the total plasma clearance of 51-chromium ethylenediamine tetra......-acetic acid (51Cr-EDTA).

End-stage renal disease (ESRD) is managed by either lifesaving hemodialysis (HD) and peritoneal dialysis (PD) or a kidney transplant. In Malaysia, the prevalence of dialysis-treated ESRD patients has shown an exponential growth from 504 per million population (pmp) in 2005 to 1155 pmp in 2014. There were 1046 pmp patients on HD and 109 pmp patients on PD in 2014. Kidney transplants are limited due to lack of donors. Malaysia adopts public-private financing model for dialysis. Majority of HD patients were treated in the private sector but almost all PD patients were treated in government facilities. Inequality in access to dialysis is visible within geographical regions where majority of HD centres are scattered around developed areas. The expenditure on dialysis has been escalating in recent years but economic evaluations of dialysis modalities are scarce. Evidence shows that health policies and reimbursement strategies influence dialysis provision. Increased uptake of PD can produce significant economic benefits and improve patients' access to dialysis. As a result, some countries implemented a PD-First or Favored Policy to expand PD use. Thus, a current comparative costs analysis of dialysis is strongly recommended to assist decision-makers to establish a more equitable and economically sustainable dialysis provision in the future.

Restless legs syndrome (RLS) is an extremely distressing problem experienced by patients on dialysis; the prevalence appears to be greater than in the general population, with a wide variation from 6.6% to 80%. The diagnosis of RLS is a clinical one, and its definition has been clarified and standardized by internationally recognized diagnostic criteria, published in 1995 by the International Restless Legs Syndrome Study Group (IRLSSG). This study was designed to find out the prevalence of RLS in Saudi patients with end-stage renal disease (ESRD) on maintenance dialysis. This is a cross sectional study carried out between May and Sept 2007 at two centers, King Abdulaziz Medical City-King Fahad National Guard Hospital (KAMC-KFNGH), Riyadh and King Faisal Specialist Hospital and Research Centre (KFHRC), Jeddah, Saudi Arabia. Data were gathered on 227 Saudi patients on chronic maintenance hemodialysis or chronic peritoneal dialysis. The prevalence of RLS was measured using IRLSSG's RLS Questionnaire (RLSQ). Potential risk factors for RLS including other sleep disorders, underlying cause of chronic renal failure, duration on dialysis, dialysis shift, biochemical tests and demographic data were also evaluated. The overall prevalence of RLS was 50.22% including 53.7% males and 46.3% females. Their mean age was 55.7 + - 17.2 years and mean duration on dialysis 40.4 + - 37.8 months. Significant predictors of RLS were history of diabetes mellitus (DM), coffee intake, afternoon dialysis, gender and type of dialysis (P= 0.03, 0.01, < 0.001, 0.05 and 0.009 respectively). Patients with RLS were found to be at increased risk of having insomnia and excessive daytime sleepiness (EDS) (P= < 0.001 and 0.001, respectively). Our study suggests that RLS is a very common problem in dialysis population and was significantly associated with other sleep disorders, particularly insomnia, and EDS.

Full Text Available Objective: Haemodialysis and peritoneal dialysis renal replacement treatment options are in clinical equipoise, although the cost of haemodialysis to the National Health Service is £16,411/patient/year greater than peritoneal dialysis. Treatment decision-making takes place during the pre-dialysis year when estimated glomerular filtration rate drops to between 15 and 30 mL/min/1.73 m2. Renal disease can be familial, and the majority of patients have considerable health service experience when they approach these treatment decisions. Factors affecting patient treatment decisions are currently unknown. The objective of this article is to explore data from a wider study in specific relation to the types of vicarious learning experiences reported by pre-dialysis patients. Methods: A qualitative study utilised unstructured interviews and grounded theory analysis during the participant’s pre-dialysis year. The interview cohort comprised 20 pre-dialysis participants between 24 and 80 years of age. Grounded theory design entailed thematic sampling and analysis, scrutinised by secondary coding and checked with participants. Participants were recruited from routine renal clinics at two local hospitals when their estimated glomerular filtration rate was between 15 and 30 mL/min/1.73 m2. Results: Vicarious learning that contributed to treatment decision-making fell into three main categories: planned vicarious leaning, unplanned vicarious learning and historical vicarious experiences. Conclusion: Exploration and acknowledgement of service users’ prior vicarious learning, by healthcare professionals, is important in understanding its potential influences on individuals’ treatment decision-making. This will enable healthcare professionals to challenge heuristic decisions based on limited information and to encourage analytic thought processes.

Pomalidomide is an immunomodulatory drug for treatment of relapsed or refractory multiple myeloma (rrMM) in patients who often have comorbid renal conditions. To assess the impact of renal impairment on pomalidomide exposure, a population pharmacokinetics (PPK) model of pomalidomide in rrMM patients with various degrees of impaired renal function was developed. Intensive and sparse pomalidomide concentration data collected from two clinical studies in rrMM patients with normal renal function, moderately impaired renal function, severely impaired renal function not requiring dialysis, and with severely impaired renal function requiring dialysis were pooled over the dose range of 2 to 4 mg, to assess specifically the influence of the impaired renal function as a categorical variable and a continuous variable on pomalidomide clearance and plasma exposure. In addition, pomalidomide concentration data collected on dialysis days from both the withdrawal (arterial) side and from the returning (venous) side of the dialyzer, from rrMM patients with severely impaired renal function requiring dialysis, were used to assess the extent to which dialysis contributes to the removal of pomalidomide from blood circulation. PPK analyses demonstrated that moderate to severe renal impairment not requiring dialysis has no influence on pomalidomide clearance or plasma exposure, as compared to those patients with normal renal function, while pomalidomide exposure increased approximately 35% in patients with severe renal impairment requiring dialysis on nondialysis days. In addition, dialysis increased total body pomalidomide clearance from 5 L/h to 12 L/h, indicating that dialysis will significantly remove pomalidomide from the blood circulation. Thus, pomalidomide should be administered post-dialysis on the days of dialysis.

A prime determinant in selecting dialysis modality: peritoneal dialysis patient survival

Full Text Available The number of patients with end-stage renal disease (ESRD has rapidly increased, as has the cost of dialysis. Peritoneal dialysis (PD is an established treatment for ESRD patients worldwide; it has a variety of advantages, including autonomy and flexibility, as well as economic benefits in many countries compared to hemodialysis (HD. However, the long-term survival rate of PD remains poor. Although direct comparison of survival rate between the dialysis modalities by randomized controlled trials is difficult due to the ethical issues, it has always been a crucial point when deciding which dialysis modality should be recommended to patients. Recently, in many countries, including the United States, Brazil, Spain, Australia, and New Zealand, the survival rate in PD patients has significantly improved. PD patient survival in Korea has also improved, but Korean PD patients are known to have higher risk of mortality and major adverse cardiovascular, cerebrovascular events than HD patients. Herein, we further evaluate why Korean PD patients had worse outcomes; we suggest that special attention should be paid to patients with diabetes, coronary artery disease, or congestive heart failure when they choose PD as the first dialysis modality in order to reduce mortality risk.

Vitamins in dialysis: who, when and how much?

2014-05-01

Despite the significant technical evolution of the blood purification methods, cardiovascular morbidity and mortality in dialysis patients is still several times higher than that observed in the general population. Vitamins are playing a crucial role in multiple key metabolic pathways. Due to multiple factors, dialysis patients present very often hypo- or hypervitaminosis for a broad range of vitamins. Dialysis in the context of renal replacement therapy is associated with a non-physiological potassium-sparing dietetic regime. Additionally, there is a non-selective intradialytic loss of micro- and macronutrients, deranged intracellular kinetics and gastrointestinal malabsorption due to uratemia. Frequent treatment with antibiotics due to infections associated with the acquired uremia-related immunosuppression may derange the vitamin-producing intestinal microflora. Certain agents prescribed in the context of renal failure or other conditions may reduce the absorption of vitamins from the gastrointestinal tract. These factors may deplete a dialysis patient from vitamins, especially the ones with antioxidant activity that may be associated with cardioprotective properties. In other cases, vitamins metabolized and excreted by the kidneys may be accumulated and exert toxic effects. The scope of this paper is to describe the main issues on vitamin therapy in dialysis patients in view of the ever contradictory opinions and practices.

Full Text Available Patients with end-stage renal failure (ESRF on maintenance dialysis, commonly develop secondary hyperparathyroidism and renal osteodystrophy (ROD. Alfacalcidol, taken orally or administered intravenously, is known to reverse these complications. In this study, 19 ESRF patients, who were on dialysis (13 on hemodialysis and six on peritoneal dialysis for longer than six months and having serum parathormone levels at least four times normal and serum calcium less than 2.1 mmol/L, were randomly allocated to treatment with oral or intravenous (i.v. alfacalcidol for a period of 12 months. There were six patients on hemodialysis (HD and three on peritoneal dialysis (PD in the oral treatment group while in the i.v. group there were seven patients on HD and three on PD. Clinical and serial biochemical assessments showed no statistically significant difference between the orally- and i.v.-treated patients in terms of suppressing secondary hyperparathyroidism and osteodystrophy. However, patients with features of mild ROD on bone histology, had more satisfactory changes in biochemistry when compared to others. Our results further support the use of intermittent oral alfacalcidol in ESRF patients because of its cost effectiveness, ease of administration and convenience, especially for peritoneal dialysis patients.

Renal failure secondary to ANCA-associated vasculitis represents a clinical and therapeutic challenge. In this study, we aimed to assess the treatment response rates and long-term outcomes of vasculitis patients presenting with renal failure. This retrospective study included 151 patients with renal vasculitis from three hospitals who underwent a renal biopsy between 1997 and 2014. Patients with renal failure which required dialysis at the onset were compared to those presenting with more preserved renal function. The primary end point was treatment response and patient surivival. Patients with severe renal involvement had a lower response to treatment compared to those having preserved renal function (26.6 versus 93.4%; p renal recovery (41.6 versus 12.5%; p = 0.05). A higher incidence of severe infections was observed among patients with severe renal involvement (38.4 versus 18.1%, p = 0.01). The mortality rate was significantly higher among vasculitis patients presenting with renal failure (53.8 versus 22.2%, p = 0.001). Global survival at 1 and 5 years was 60 and 47% in patients requiring dialysis compared with 90 and 80% among those with more preserved renal function (p renal dysfunction represents an independent risk factor for patient survival in renal vasculitis. Patients requiring dialysis associate a lower response rate to immunosuppressive therapy and a higher incidence of severe infections.

Heart failure patients requiring total artificial heart (TAH) support often have concomitant renal insufficiency (RI). We sought to quantify renal function recovery in patients supported with TAH at our institution. Renal function data at 30, 90, and 180 days after TAH implantation were analyzed for patients with RI, defined as hemodialysis supported or an estimated glomerular filtration rate (eGFR) less than 60 ml/min/1.73 m. Between January 2008 and December 2013, 20 of the 46 (43.5%) TAH recipients (age 51 ± 9 years, 85% men) had RI, mean preoperative eGFR of 48 ± 7 ml/min/1.73 m. Renal function recovery was noted at each follow-up interval: increment in eGFR (ml/min/1.73 m) at 30, 90, and 180 days was 21 ± 35 (p = 0.1), 16.5 ± 18 (p = 0.05), and 10 ± 9 (p = 0.1), respectively. Six patients (30%) required preoperative dialysis. Of these, four recovered renal function, one remained on dialysis, and one died. Six patients (30%) required new-onset dialysis. Of these, three recovered renal function and three died. Overall, 75% (15 of 20) of patients' renal function improved with TAH support. Total artificial heart support improved renal function in 75% of patients with pre-existing significant RI, including those who required preoperative dialysis.

Full Text Available Background: Physicians' perceptions and opinions may influence when to initiate dialysis. Objective: To examine providers' perspectives and opinions regarding the timing of dialysis initiation. Design: Online survey. Setting: Community and academic dialysis practices in Canada. Participants: A nationally-representative sample of dialysis providers. Measurements and Methods: Dialysis providers opinions assessing reasons to initiate dialysis at low or high eGFR. Responses were obtained using a 9-point Likert scale. Early dialysis was defined as initiation of dialysis in an individual with an eGFR greater than or equal to 10.5 ml/min/m 2 . A detailed survey was emailed to all members of the Canadian Society of Nephrology (CSN in February 2013. The survey was designed and pre-tested to evaluate duration and ease of administration. Results: One hundred and forty one (25% response rate physicians participated in the survey. The majority were from urban, academic centres and practiced in regionally administered renal programs. Very few respondents had a formal policy regarding the timing of dialysis initiation or formally reviewed new dialysis starts (N = 4, 3.1%. The majority of respondents were either neutral or disagreed that late compared to early dialysis initiation improved outcomes (85–88%, had a negative impact on quality of life (89%, worsened AVF or PD use (84–90%, led to sicker patients (83% or was cost effective (61%. Fifty-seven percent of respondents felt uremic symptoms occurred earlier in patients with advancing age or co-morbid illness. Half (51.8% of the respondents felt there was an absolute eGFR at which they would initiate dialysis in an asymptomatic patient. The majority of respondents would initiate dialysis for classic indications for dialysis, such as volume overload (90.1% and cachexia (83.7% however a significant number chose other factors that may lead them to early dialysis initiation including avoiding an emergency (28

Among 656 patients undergoing surgery for abdominal aortic aneurysm, 81 patients (12%) developed postoperative renal failure. Before operation hypotension and shock occurred in 88% of the patients with ruptured aneurysm, whereas none of the patients operated electively were hypotensive. Dialysis...... was performed in 32 patients, while the remaining 49 patients were managed without dialysis. Within 30 days after the operation 47 patients (58%) had died. There was no difference in mortality between patients in dialysis and patients managed without dialysis. Thirteen patients died during follow-up. In six...... cases the death was caused by renal failure only or in combination with failure of other organs. Analysis of the cumulative survival shows that, if the patients survive the postoperative period, their life expectancy is comparable to that of patients without renal complications....

Residual renal function and the integrity of the peritoneal membrane contribute to morbidity and mortality among patients treated with peritoneal dialysis. Glucose and its degradation products likely contribute to the deterioration of the remnant kidney and damage to the peritoneum. Benfotiamine decreases glucose-induced tissue damage, suggesting the potential for benefit in peritoneal dialysis. Here, in a model of peritoneal dialysis in uremic rats, treatment with benfotiamine decreased peri...

CA.R.PE.DI.E.M. (Cardio-Renal Pediatric Dialysis Emergency Machine): evolution of continuous renal replacement therapies in infants. A personal journey.

2012-08-01

Pedriatric acute kidney injury (AKI) is a well-described clinical syndrome that is characterized by a reduction of both the urine output and glomerular filtration rate. AKI in critically ill children is typically associated with multiple organ dysfunction. A dramatic increase in the incidence of AKI in pediatric intensive care units has been observed in the last 10 years. Unfortunately, the absence of sufficiently effective preventive and therapeutic measures at the present time has limited significant improvements in AKI care. Morality in patients with severe AKI remains unacceptably high (>50 %), with renal replacement therapy (RRT) remaining the most effective form of support for these patients. Despite technological advances during the last 10 years which have resulted in the development of the so-called "third-generation dialysis machines" that are characterized by the highest level of safety and accuracy, a truly pedriatric RRT system has never been developed. Consequently, dialysis/hemofiltration in critically ill children is currently performed by adapting adult systems to the much smaller pediatric patients. In particular, research in this field should focus on children weighing less than 10 kg for whom the delivery of RRT is a clinical and technological challenge. We describe here the evolution of pediatric RRT during the last 30 years and report in detail on the CARPEDIEM project, which has recently been established to finally provide neonates and infants with a reliable dialysis machine that is specifically designed for this age group.

Premature aging of both CD4 + -regulatory- (Tregs) and CD4 + -responder-T-cells (Tresps) in end-stage renal disease (ESRD) patients is expected to affect the success of later kidney transplantation. Both T-cell populations are released from the thymus as inducible co-stimulatory (ICOS + -) and ICOS - -recent thymic emigrant (RTE)-Tregs/Tresps, which differ primarily in their proliferative capacities. In this study, we analysed the effect of ESRD and subsequent renal replacement therapies on the differentiation of ICOS + - and ICOS - -RTE-Tregs/Tresps into ICOS + - or ICOS - -CD31 - -Memory-Tregs/Tresps and examined whether diverging pathways affected the suppressive activity of ICOS + - and ICOS - -Tregs in co-culture with autologous Tresps. Compared to healthy controls, we found an increased differentiation of ICOS + -RTE-Tregs/Tresps and ICOS - -RTE-Tregs via CD31 + -memory-Tregs/Tresps into CD31 - -memory-Tregs/Tresps in ESRD and dialysis patients. In contrast, ICOS - -RTE-Tresps showed an increased differentiation via ICOS - -mature naïve (MN)-Tresps into CD31 - -memory-Tresps. Thereby, the ratio of ICOS + -Tregs/ICOS + -Tresps was not changed, while that of ICOS - -Tregs/ICOS - -Tresps was significantly increased. This differentiation preserved the suppressive activity of both Treg populations in ESRD and partly in dialysis patients. After transplantation, the increased differentiation of ICOS + - and ICOS - -RTE-Tresps proceeded, while that of ICOS + -RTE-Tregs ceased and that of ICOS - -RTE-Tregs switched to an increased differentiation via ICOS - -MN-Tregs. Consequently, the ratios of ICOS + -Tregs/ICOS + -Tresps and of ICOS - -Tregs/ICOS - -Tresps decreased significantly, reducing the suppressive activity of Tregs markedly. Our data reveal that an increased tolerance-inducing differentiation of ICOS + - and ICOS - -Tregs preserves the functional activity of Tregs in ESRD patients, but this cannot be maintained during long-term renal replacement therapy

The first renal transplant in Iran was carried out in 1967. The renal transplant program severely lagged behind hemodialysis in growth until 1988. In 1988, a controlled LURD renal transplant program was adopted to provide kidneys for the large number of dialysis patients needing a renal transplant. There was no cadaveric donor transplant program. By the end of 1999, a total of 9,535 renal transplants were performed and the renal transplant waiting list of the country had been eliminated. In Iran's LURD renal transplant program, the Dialysis and Transplant Patients Association introduces the volunteer LURD to the recipient and the transplant team. There are no middlemen and no incentives for transplant teams. The government pays all of the hospital expenses for transplantation. Many poor patients are able to afford LURD transplantation and more than 50% of our LURD transplant recipients are from the poor socioeconomic class. Ethical issues within the program are under the strict observation of the transplant teams and the Iranian Society for Organ Transplantation. We have noted that many LURD transplant recipients had a potential LRD who did not donate for cultural reasons or who was reluctant to donate. In the presence of a controlled LURD renal transplant program, we feel it is more ethical to perform a paid renal transplant from volunteer LURD than a renal transplant from an LRD who may be under family pressure or coerced. The patient and graft survival rates reported from our unit are comparable to the results of renal transplants reported from centers of some other countries. Some patient deaths and graft losses could have been prevented if our transplant units were not deficient with respect to laboratory facilities and access to pharmaceutical agents. In April 2000, legislation recognizing brain death and cadaveric organ transplantation passed our parliament. Strong cultural barriers may limit the scale of cadaver donor transplantation in the coming years and

In a previous survey we revealed uncertainty among responders about (a) whether or not to perform hemodialysis in patients with severely reduced renal function who had received contrast medium; and (b) when to perform hemodialysis in patients on regular treatment with hemodialysis or continuous ambulatory dialysis who received contrast medium. Therefore, the Contrast Media Safety Committee of The European Society of Urogenital Radiology decided to review the literature and to issue guidelines. The committee performed a Medline search. Based on this, a report and guidelines were prepared. The report was discussed at the Ninth European Symposium on Urogenital Radiology in Genoa, Italy. Hemodialysis and peritoneal dialysis safely remove both iodinated and gadolinium-based contrast media. The effectiveness of hemodialysis depends on many factors including blood and dialysate flow rate, permeability of dialysis membrane, duration of hemodialysis and molecular size, protein binding, hydrophilicity, and electrical charge of the contrast medium. Generally, several hemodialysis sessions are needed to removal all contrast medium, whereas it takes 3 weeks for continuous ambulatory dialysis to remove the agent completely. There is no need to schedule the dialysis in relation to the injection of iodinated or MR contrast media or the injection of contrast agent in relation to the dialysis program. Hemodialysis does not protect poorly functioning kidneys against contrast-medium-induced nephrotoxicity. Simple guidelines are given. (orig.)

Home extended hours hemodialysis improves some measurable biological and quality-of-life parameters over conventional renal replacement therapies in patients with end-stage renal disease. Published small studies evaluating costs have shown savings in terms of ongoing operating costs with this modality. However, all estimates need to include the total costs, including infrastructure, patient training, and maintenance; patient attrition by death, transplantation, technique failure; and the necessity of in-center dialysis. We describe a comprehensive funding model for a large centrally administered but locally delivered home hemodialysis program in British Columbia, Canada that covered 122 patients, of which 113 were still in the program at study end. The majority of patients performed home nocturnal hemodialysis in this 2-year retrospective study. All training periods, both in-center and in-home dialysis, medications, hospitalizations, and deaths were captured using our provincial renal database and vital statistics. Comparative data from the provincial database and pricing models were used for costing purposes. The total comprehensive costs per patient-incorporating startup, home, and in-center dialysis; medications; home remodeling; and consumables-was $59,179 for years 2004-2005 and $48,648 for 2005-2006. The home dialysis patients required multiple in-center dialysis runs, significantly contributing to the overall costs. Our study describes a valid, comprehensive funding model delineating reliable cost estimates of starting and maintaining a large home-based hemodialysis program. Consideration of hidden costs is important for administrators and planners to take into account when designing budgets for home hemodialysis.

Haemodialysis at home: review of current dialysis machines.

Science.gov (United States)

Haroon, Sabrina; Davenport, Andrew

2018-04-26

Only a minority of patients with chronic kidney disease treated by hemodialysis are currently treated at home. Until relatively recently, the only type of hemodialysis machine available for these patients was a slightly smaller version of the standard machines used for in-center dialysis treatments. Areas covered: There are now an alternative generation of dialysis machines specifically designed for home hemodialysis. The home dialysis patient wants a smaller machine, which is intuitive to use, easy to trouble shoot, robust and reliable, quick to setup and put away, requiring minimal waste disposal. The machines designed for home dialysis have some similarities in terms of touch-screen patient interfaces, and using pre-prepared cartridges to speed up setting up the machine. On the other hand, they differ in terms of whether they use slower or standard dialysate flows, prepare batches of dialysis fluid, require separate water purification equipment, or whether this is integrated, or use pre-prepared sterile bags of dialysis fluid. Expert commentary: Dialysis machine complexity is one of the hurdles reducing the number of patients opting for home hemodialysis and the introduction of the newer generation of dialysis machines designed for ease of use will hopefully increase the number of patients opting for home hemodialysis.

Dialysis Exercise Team: The Way to Sustain Exercise Programs in Hemodialysis Patients

Directory of Open Access Journals (Sweden)

Alessandro Capitanini

Full Text Available Patients affected by end-stage renal disease (ESRD show quite lower physical activity and exercise capacity when compared to healthy individuals. In addition, a sedentary lifestyle is favoured by lack of a specific counseling on exercise implementation in the nephrology care setting. Increasing physical activity level should represent a goal for every dialysis patient care management. Three crucial elements of clinical care may contribute to sustain a hemodialysis exercise program: a involvement of exercise professionals, b real commitment of nephrologists and dialysis professionals, c individual patient adaptation of the exercise program. Dialysis staff have a crucial role to encourage and assist patients during intra-dialysis exercise, but other professionals should be included in the ideal “exercise team” for dialysis patients. Evaluation of general condition, comorbidities (especially cardiovascular, nutritional status and physical exercise capacity are mandatory to propose an exercise program, in either extra-dialysis or intra-dialysis setting. To this aim, nephrologist should lead a team of specialists and professionals including cardiologist, physiotherapist, exercise physiologist, renal dietician and nurse. In this scenario, dialysis nurses play a pivotal role since they guarantee a constant and direct approach. Unfortunately dialysis staff may often lack of information and formation about exercise management while they take care patients during the dialysis session. Building an effective exercise team, promoting the culture of exercise and increasing physical activity levels lead to a more complete and modern clinical care management of ESRD patients.

The current role of nurses in the management of critically ill patients needing continuous renal replacement therapies is clearly fundamental. The care of these complex patients is typically shared by critical care and dialysis nurses: their precise duties may vary from country to country. To clarify this issue we conducted a national-level survey at a recent Italian course on nursing practices during continuous renal replacement therapies. A total of 119 questionnaires were analysed. The participants, who were equally divided between critical care and dialysis nurses, came from 44 different hospitals and 35 Italian cities. Overall, 23% of participants answered that "the dialysis staff" were responsible for continuous renal replacement therapies in the Intensive Care Unit, while 39% answered "the critical care nurse", and 38% "a shared organization". Interestingly, less than the half of participants claimed specific continuous renal replacement therapies training was provided to employees before handling an acute dialysis machine. Finally, about 60% of participants had experience of extra-corporeal membrane oxygenation machines used in conjunction with continuous renal replacement therapies. Workload coordination and management of critically ill patients undergoing continuous renal replacement therapies in Italy is not standardized. At present, the duties of critical care and dialysis nurses vary significantly across the country. They frequently overlap or leave gaps in the assistance received by patients. The role of nurses involved in the care of continuous renal replacement therapies patients in Italy currently requires better organization, possibly starting with intensive standardized training and educational programs.

Should ribavirin be used to treat hepatitis C in dialysis patients?

2011-01-01

Hepatitis C virus infection adversely affects outcomes in patients with chronic kidney disease undergoing maintenance dialysis. Pegylated interferon and ribavirin, the standard-of-care treatment in patients with intact renal function, is associated with severe side effects, toxicity, and high dropout rates in this population. Ribavirin has an important role in maintaining antiviral response following completion of therapy and increases sustained viral response (SVR) rates. However, the use of ribavirin in dialysis patients has been limited by the high frequency of severe hemolytic anemia and is currently reserved for study protocols and highly selected candidates treated at experienced centers. Encouraging data from small trials have shown a significant increase in SVR rates with the use of different dosing regimens of ribavirin in addition to interferon-based therapy and aggressive erythroid-stimulating agent support in dialysis patients. Use of ribavirin in selected dialysis patients, particularly renal transplant candidates, by experienced clinicians is appropriate. © 2011 Wiley Periodicals, Inc.

It is well recognized that patients with end stage renal diseases (ESRD) have hyper-plastic parathyroid glands. In most patients, a decrease in parathyroid hormone (PTH) occurs by about 1 year after renal transplantation. However, some renal transplant recipients continue to have elevated level of PTH. We prospectively evaluated 121 patients undergoing renal transplantation between August 2000 and 2002. The duration of dialysis, calcium (Ca), phosphorus (P), albumin, creatinine and iPTH levels were recorded prior to transplantation and three months and one year after transplantation. These 121 patients were on dialysis for an average period of 17.4 months prior to transplantation. An increase in the serum Ca and a decrease in serum P and iPTH level was seen in the patients after transplantation (P< 0.001). Hyperparathyroidism was in 12 (9.9%) and 7 (5.7%) patients three months and one year after transplantation respectively. Elderly patients and patients with longer duration on dialysis had an increased risk of developing post transplant hyperparathyroidism and hypercalcemia in the first year post transplant (P< 0.05). In conclusion age and duration on dialysis before transplantation seems to be important risk factors for post transplant hyperparathyroidism. (author)

Peritoneal dialysis (PD) contributes to restore acid-base homeostasis in patients with end-stage renal disease. The transport pathways for buffers and carbon dioxide (CO2) across the peritoneal membrane remain poorly understood. Combining well-established PD protocols, whole-body plethysmography and renal function studies in mice, we investigated molecular mechanisms of acid-base regulation in PD, including the potential role of the water channel aquaporin-1 (AQP1). After instillation in peritoneal cavity, the pH of acidic dialysis solutions increased within minutes to rapidly equilibrate with blood pH, whereas the neutral pH of biocompatible solutions remained constant. Predictions from the three-pore model of peritoneal transport suggested that local production of HCO3- accounts at least in part for the changes in intraperitoneal pH observed with acidic solutions. Carbonic anhydrase (CA) isoforms were evidenced in the peritoneal membrane and their inhibition with acetazolamide significantly decreased local production of HCO3- and delayed changes in intraperitoneal pH. On the contrary, genetic deletion of AQP1 had no effect on peritoneal transport of buffers and diffusion of CO2. Besides intraperitoneal modifications, the use of acidic dialysis solutions enhanced acid excretion both at pulmonary and renal levels. These findings suggest that changes in intraperitoneal pH during PD are mediated by bidirectional buffer transport and by CA-mediated production of HCO3- in the membrane. The use of acidic solutions enhances acid excretion through respiratory and renal responses, which should be considered in patients with renal failure. © The Author 2017.

Malnutrition is highly prevalent in Malaysian dialysis patients and there is a need for a valid screening tool for early identification and management. This cross-sectional study aims to examine the sensitivity of the Dialysis Malnutrition Score (DMS) and Malnutrition Inflammation Score (MIS) tools in predicting protein-energy wasting (PEW) among Malaysian dialysis patients. A total of 155 haemodialysis (HD) and 90 peritoneal dialysis (PD) patients were screened for risk of malnutrition using DMS and MIS and comparisons were made with established guidelines by International Society of Renal Nutrition and Metabolism (ISRNM) for PEW. MIS cut-off score of >=5 indicated presence of malnutrition in all patients. A total of 59% of HD and 83% of PD patients had PEW by ISRNM criteria. Based on DMS, 73% of HD and 71% of PD patients exhibited moderate malnutrition, whilst using MIS, 88% and 90%, respectively were malnourished. DMS and MIS correlated significantly in HD (r2=0.552, pmalnutrition classification were established (score >=5) for use amongst Malaysian dialysis patients. Both DMS and MIS are valid tools to be used for nutrition screening of dialysis patients especially those undergoing peritoneal dialysis. The DMS may be a more practical and simpler tool to be utilized in the Malaysian dialysis settings as it does not require laboratory markers.

Are Diuretics Underutilized in Dialysis Patients?

Science.gov (United States)

Trinh, Emilie; Bargman, Joanne M

2016-09-01

While oral diuretics are commonly used in patients with chronic kidney disease for the management of volume and blood pressure, they are often discontinued upon initiation of dialysis. We suggest that diuretics are considerably underutilized in peritoneal dialysis and haemodialysis patients despite numerous potential benefits and few side effects. Moreover, when diuretics are used, optimal doses are not always prescribed. In peritoneal dialysis, the use of diuretics can improve volume status and minimize the need for higher glucose-containing solutions. In patients on haemodialysis, diuretics can help lessen interdialytic weight gain, resulting in decreased ultrafiltration rates and fewer episodes of intradialytic hypotension. This paper will review the mechanism of action of diuretics in patients with renal insufficiency, quantify the risk of side effects and elaborate on the potential advantages of diuretic use in peritoneal dialysis and hemodialysis patients with residual kidney function. © 2016 Wiley Periodicals, Inc.

The optimal dialysis dose for acute kidney injury is a matter of great controversy. Clinical trials, predominantly single-center studies, have shown conflicting results. The Acute Renal Failure Trial Network (ATN) Study was designed to compare clinical outcomes between patients allocated to an intensive dose versus a less-intensive dose of renal replacement therapy. Recently, the results of this large randomized controlled multicenter study were published. The present article will discuss certain aspects of this trial: the overall design, the baseline patient characteristics, and comparison of the results with earlier studies. Finally, the article will address the implications of the ATN Study results for clinical practice.

Water-Permeable Dialysis Membranes for Multi-Layered Micro Dialysis System

Directory of Open Access Journals (Sweden)

Naoya eTo

2015-06-01

Full Text Available This paper presents the development of water-permeable dialysis membranes that are suitable for an implantable microdialysis system that does not use dialysis fluid. We developed a microdialysis system integrating microfluidic channels and nanoporous filtering membranes made of polyethersulfone (PES, aiming at a fully implantable system that drastically improves the quality of life of patients. Simplicity of the total system is crucial for the implantable dialysis system, where the pumps and storage tanks for the dialysis fluid pose problems. Hence, we focus on hemofiltration, which does not require the dialysis fluid but water-permeable membranes. We investigated the water-permeability of the PES membrane with respect to the concentrations of the PES, the additives, and the solvents in the casting solution. Sufficiently water-permeable membranes were found through in vitro experiments using whole bovine blood. The filtrate was verified to have the concentrations of low-molecular-weight molecules, such as sodium, potassium, urea, and creatinine, while proteins, such as albumin, were successfully blocked by the membrane. We conducted in vivo experiments using rats, where the system was connected to the femoral artery and jugular vein. The filtrate was successfully collected without any leakage of blood inside the system and it did not contain albumin but low-molecular-weight molecules whose concentrations were identical to those of the blood. The rat model with renal failure showed 100% increase of creatinine in 5 h, while rats connected to the system showed only a 7.4% increase, which verified the effectiveness of the proposed microdialysis system.

Predictive Modelling Risk Calculators and the Non Dialysis Pathway.

This guideline will review the current prediction models and survival/mortality scores available for decision making in patients with advanced kidney disease who are being considered for a non-dialysis treatment pathway. Risk prediction is gaining increasing attention with emerging literature suggesting improved patient outcomes through individualised risk prediction (1). Predictive models help inform the nephrologist and the renal palliative care specialists in their discussions with patients and families about suitability or otherwise of dialysis. Clinical decision making in the care of end stage kidney disease (ESKD) patients on a non-dialysis treatment pathway is currently governed by several observational trials (3). Despite the paucity of evidence based medicine in this field, it is becoming evident that the survival advantages associated with renal replacement therapy in these often elderly patients with multiple co-morbidities and limited functional status may be negated by loss of quality of life (7) (6), further functional decline (5, 8), increased complications and hospitalisations.

When compared to hemodialysis, peritoneal dialysis is very simple yet low cost method of renal replacement therapy. Series of studies have shown its superiority in preserving residual renal function, postponing uremic complications, maintaining the acid-base balance and achieving better post-transplant outcome in patients treated with this method. Despite obvious advantages, its role in the treatment of chronic kidney disease is still not as important as it should be. Metabolic acidosis is an inevitable complication associated with progressive loss of kidney function. Its impact on mineral and muscle metabolism, residual renal function, allograft function and anemia is very complex but can be successfully managed. The aim of our study was to evaluate the efficiency in preserving the acid-base balance in patients undergoing peritoneal dialysis at Zagreb University Hospital Center. Twenty-eight patients were enrolled in the study. The mean time spent on the treatment was 32.39 ± 43.43 months. Only lactate-buffered peritoneal dialysis fluids were used in the treatment. Acid-base balance was completely maintained in 73.07% of patients; 11.54% of patients were found in the state of mild metabolic acidosis, and the same percentage of patients were in the state of mild metabolic alkalosis. In one patient, mixed alkalosis with respiratory and metabolic component was present. The results of this study showed that acid-base balance could be maintained successfully in patients undergoing peritoneal dialysis, even only with lactate-buffered solutions included in the treatment, although they were continuously proclaimed as inferior in comparison with bicarbonate-buffered ones. In well educated and informed patients who carefully use this method, accompanied by the attentive and thorough care of their physicians, this method can provide quality continuous replacement of lost renal function as well as better quality of life.

Peritoneal dialysis in Asia.

Cheng, I K

The socioeconomic status of Asian countries is diverse, and government reimbursement policies for treatment of patients suffering from end-stage renal disease (ESRD) vary greatly from one country to another. Both of these factors have a major impact not only on the choice of treatment for ESRD but also on the utilization of peritoneal dialysis (PD) in this region. Based on the data collected from 11 representative Asian countries, several observations can be made. First, the treatment rates for ESRD in these countries correlated closely with their gross domestic product (GDP) per capita income. Second, the PD utilization rate appeared to have a biphasic relationship with the GDP per capita income and treatment rate, in that countries with the highest and the lowest treatment rates tended to have lower PD utilization rates, whereas countries with modest treatment rates tended to have higher PD utilization rates. The reason for low PD utilization in countries with the highest treatment rates differs from that in countries with low treatment rates. In the former, because of full government reimbursement, there is little physician incentive to introduce PD as an alternative form of ESRD treatment to in-center hemodialysis (HD), whereas in the latter, the complete lack of government reimbursement prevents the introduction of PD as a form of treatment. This pattern is likely to change in the future because, of the 11 countries surveyed, all except Thailand have recorded a growth rate which is higher for PD than HD over the last three years. The rate of utilization of different PD systems varies greatly among different Asian countries. Automated PD has yet to gain popularity in Asia. Conventional straight-line systems remain the dominant PD systems in use in Hong Kong, Korea, Thailand, and the Philippines, while in Malaysia and Singapore UV germicidal connection devices are most popular. However, in all these countries there has been a progressive shift over the last

The impact of education on health care outcome has been studied in the past, but its role in the dialysis population is unclear. In this report, we evaluated this association. We used the United States Renal Data System data of end-stage renal disease patients aged 18 years. Education level at the time of end-stage renal disease onset was the primary variable of interest. The outcome of the study was patient mortality. We used four categories of education level: 0 = less than 12 years of education; 1 = high school graduate; 2 = some college; 3 = college graduate. Subgroups based on age, race, sex, donor type, and diabetic status were also analyzed. After adjustments for covariates in the Cox model, using individuals with less than 12 years of education as a reference, patients with college education showed decreased mortality with hazard ratio of 0.81 (95% confidence interval 0.69–0.95), P = 0.010. In conclusion, we showed that higher education level is associated with improved survival of patients on dialysis.

Tissue accumulation of advanced glycation end-products (AGE) is thought to be a contributing factor 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 shown associations with CVD in haemodialysis patients. The present study aimed to evaluate relationships of skin autofluorescence to renal function as well as CVD in pre-dialysis patients with chronic kidney disease (CKD). Subjects in this cross-sectional analysis comprised 304 pre-dialysis CKD patients [median age, 62.0 years; median estimated glomerular filtration rate (eGFR), 54.3 mL/min/1.73 m(2); diabetes, n = 81 (26.6%)]. AGE accumulation in skin was assessed by skin autofluorescence using an autofluorescence reader. Relationships between skin autofluorescence, eGFR, CVD history and other parameters were evaluated. Skin autofluorescence correlated negatively with eGFR (r = -0.42, P skin autofluorescence with age, presence of diabetes, eGFR and CVD history in CKD patients (R(2) = 30%). Age, male gender, smoking history, skin autofluorescence and eGFR were significantly correlated with CVD history, and multiple logistic regression analysis identified age [odds ratio (OR), 1.09; 95% confidence interval (CI), 1.03-1.15; P skin autofluorescence (OR, 3.74; 95%CI, 1.54-9.24; P skin autofluorescence increased as GFR decreased and was related to CVD history in CKD patients. Non-invasive autofluorescence readers may provide potential markers for clinical risk assessment in pre-dialysis CKD patients.

To investigate the impacts of availability of pre-mixed solutions and computerized order entry on nephrologists' choice of the initial mode of renal replacement therapy in acute renal failure. We studied 898 patients with acute renal failure in 3 consecutive eras: era 1 (custom-mixed solution; n = 309), era 2 (pre-mixed commercial solution; n = 324), and era 3 (post-computerized order entry; n = 265). The proportion of patients treated with renal replacement therapy and the time from consult to initiation of continuous renal replacement therapy was similar in the 3 eras. Following introduction of the pre-mixed solution, the proportion of patients treated with continuous renal replacement therapy increased (20% vs. 33%; p mixed solution increases the likelihood of initiating continuous renal replacement therapy in acute renal failure, initiating it at a lower creatinine and for older patients, use of continuous veno-venous hemodialysis and higher prescribed continuous renal replacement therapy dose. Computerized order entry implementation is associated with an additional increase in the use of continuous veno-venous hemodialysis, higher total prescribed dialysis dose, and use of CRRT among an increasing number of patients not on mechanical ventilation. The effect of these changes on patient survival is not significant.

Sixty children and adolescents in end-stage renal failure who were undergoing either haemodialysis or continuous ambulatory peritoneal dialysis at one of five United Kingdom dialysis centres were assessed on psychosocial adjustment and adherence to their fluid intake, diet and medication regimes. Parental adjustment was also measured and data on sociodemographic and treatment history variables collected. A structured family interview and standardised questionnaire measures of anxiety, depression and behavioural disturbance were used. Multiple measures of treatment adherence were obtained, utilising children's and parents' self-reports, weight gain between dialysis, blood pressure, serum potassium level, blood urea level, dietitians' surveys and consultants' ratings. Correlational analyses showed that low treatment adherence was associated with poor adjustment to diagnosis and dialysis by children and parents (P adherence than younger children, P dialysis (P treatment of this group of children. Future research should develop and evaluate psychosocial interventions aimed at improving treatment adherence.

Peritoneal Dialysis in Western Countries.

Struijk, Dirk G

2015-12-01

Peritoneal dialysis (PD) for the treatment of end-stage renal failure was introduced in the 1960s. Nowadays it has evolved to an established therapy that is complementary to hemodialysis (HD), representing 11% of all patients treated worldwide with dialysis. Despite good clinical outcomes and similar results in patient survival between PD and HD, the penetration of PD is decreasing in the Western world. First the major events in the history of the development of PD are described. Then important insights into the physiology of peritoneal transport are discussed and linked to the changes in time observed in biopsies of the peritoneal membrane. Furthermore, the developments in peritoneal access, more biocompatible dialysate solutions, automated PD at home, the establishment of parameters for dialysis adequacy and strategies to prevent infectious complications are mentioned. Finally non-medical issues responsible for the declining penetration in the Western world are analyzed. Only after introduction of the concept of continuous ambulatory PD by Moncrief and Popovich has this treatment evolved in time to a renal replacement therapy. Of all structures present in the peritoneal membrane, the capillary endothelium offers the rate-limiting hindrance for solute and water transport for the diffusive and convective transport of solutes and osmosis. The functional and anatomical changes in the peritoneal membrane in time can be monitored by the peritoneal equilibrium test. Peritonitis incidence decreased by introduction of the Y-set and prophylaxis using mupirocin on the exit site. The decrease in the proportion of patients treated with PD in the Western world can be explained by non-medical issues such as inadequate predialysis patient education, physician experience and training, ease of HD initiation, overcapacity of in-center HD, lack of adequate infrastructure for PD treatment, costs and reimbursement issues of the treatment. (1) PD is cheaper than HD and provides a

Full Text Available Human immunodeficiency virus (HIV infection may be associated with renal impairment since about 0.4% of all HIV-positive patients develop end-stage renal disease. The share of patients with HIV infection in hemodialysis centers throughout the world ranges from 0.3% to as high as 38%. In Croatia, renal replacement therapy was needed by 1% of all the HIV-positive patients from 1985 until the end of 2014. Healthcare professionals (HP should be aware of the risks of occupational exposure to blood-borne infections in their daily work. Performing dialysis in HIV-positive patients increases the risk of exposure to HIV during the extracorporeal circulation of the infected blood. However, post-exposure prophylaxis (PEP with effective antiretroviral drugs significantly reduces the risk of infection after occupational exposure. On behalf of the Croatian Society of Nephrology, Dialysis and Transplantation, the authors of this paper have proposed recommendations for the management of HIVpositive patients on dialysis, which aim to prevent the transmission of HIV among patients and HPs. The important recommendations include the following: 1. when the need arises, it is necessary to provide HIV-positive patients with dialysis in the vicinity of their place of residence. 2. HIV-positive patients should be dialyzed with a separate hemodialysis machine in an isolated area. Alternatively, they can be dialyzed in an area for the hemodialysis of HCV-positive and/or HBVpositive patients. 3. Specialized and trained personnel should be provided during the hemodialysis procedure, together with strict compliance with the standard precautions for the prevention of blood-borne infections. 4. There should be a good and prompt cooperation with the National Referral Center for HIV infection.

End-stage renal disease carries a prognosis similar to cancer yet only 20 % of end-stage renal disease patients are referred to hospice. Furthermore, conversations between dialysis team members and patients about end-of-life planning are uncommon. Lack of provider training about how to communicate prognostic data may contribute to the limited number of end-of-life care discussions that take place with this chronically ill population. In this study, we will test the Shared Decision-Making Renal Supportive Care communication intervention to systematically elicit patient and caretaker preferences for end-of-life care so that care concordant with patients' goals can be provided. This multi-center study will deploy an intervention to improve end-of-life communication for hemodialysis patients who are at high risk of death in the ensuing six months. The intervention will be carried out as a prospective cohort with a retrospective cohort serving as the comparison group. Patients will be recruited from 16 dialysis units associated with two large academic centers in Springfield, Massachusetts and Albuquerque, New Mexico. Critical input from patient advisory boards, a stakeholder panel, and initial qualitative analysis of patient and caretaker experiences with advance care planning have informed the communication intervention. Rigorous communication training for hemodialysis social workers and providers will ensure that standardized study procedures are performed at each dialysis unit. Nephrologists and social workers will communicate prognosis and provide advance care planning in face-to-face encounters with patients and families using a social work-centered algorithm. Study outcomes including frequency and timing of hospice referrals, patient and caretaker satisfaction, quality of end-of-life discussions, and quality of death will be assessed over an 18 month period. The Shared Decision-Making Renal Supportive Care Communication intervention intends to improve discussions

Preemptive transplantation results in excellent patient and graft survival yet most transplant candidates are referred for transplantation after initiation of dialysis. The goal of this study was to determine barriers to preemptive renal transplantation. A nonvalidated questionnaire was administered to prospective kidney transplant recipients to determine factors that hindered or favored referral for transplantation before the initiation of dialysis. One hundred ninety-seven subjects referred for a primary renal transplant completed the questionnaire. Ninety-one subjects (46%) had been informed of preemptive transplantation before referral, and 80 (41%) were predialysis at the time of evaluation. The median time from diagnosis of renal disease to referral was 60 months (range, 2-444 months). In bivariate analysis, among other factors, knowledge of preemptive transplantation was highly associated (odds ratio=94.69) with referral before initiation of dialysis. Given the strong association between knowledge of preemptive transplantation and predialysis referral, this variable was not included in the multivariate analysis. Using multivariate logistic regression analysis, white recipient race, referral by a transplant nephrologist, recipient employment, and the diagnosis of polycystic kidney disease were significantly associated with presentation to the pretransplant clinic before initiation of dialysis. The principle barrier to renal transplantation referral before dialysis was patient education regarding the option of preemptive transplantation. Factors significantly associated with referral before dialysis were the diagnosis of polycystic kidney disease, white recipient race, referral by a transplant nephrologist, and employed status. Greater effort should be applied to patient education regarding preemptive transplantation early after the diagnosis of end-stage renal disease.

The optimal dialysis dose for acute kidney injury is a matter of great controversy. Clinical trials, predominantly single-center studies, have shown conflicting results. The Acute Renal Failure Trial Network (ATN) Study was designed to compare clinical outcomes between patients allocated to an intensive dose versus a less-intensive dose of renal replacement therapy. Recently, the results of this large randomized controlled multicenter study were published. The present article will discuss certain aspects of this trial: the overall design, the baseline patient characteristics, and comparison of the results with earlier studies. Finally, the article will address the implications of the ATN Study results for clinical practice. PMID:18983695

Radiation Protection issues concerning patients, public and staff must be considered carefully in hemodialysis for chronic renal failure patients scheduled for 131 I high dose therapy. In order to assess the risks related to this medical procedure, hemodialysis clearance of 131 I and contamination measurements were carried out. We have studied 12 hemodialysis procedures corresponding to 2 cases of hyperthyroidism disease (555MBq of 131 I administered) and 3 patients with carcinoma of the thyroid (5550 MBq of 131 I administered). The arterio-venous difference of 131 I across the artificial kidney and dose rate reduction at one meter of patient were measured. Contamination levels of the dialyser machine, filters and tubes were measured after dialysis with a contamination monitor. Direct read-out dosimeters were used to assess the radiation doses to nursery staff involved. The result obtained for mean 131 I clearance in blood was 75±11%. The mean dose rate reduction at one meter of the patient was 58±18%. We also checked that contamination levels for the dialyser machine, filters, tubes and accessories were lower than 10Bq/cm 2 . For the nursery staff the radiation dose was found to be lower than 0.1mSv. (author)

Background Medication adherence is thought to be around 50% in the general and dialysis population. Reducing the pill burden (PB) reduces regime complexity and can improve adherence. Increased adherence should lead to improvement in treatment outcomes and patient quality of life. There is currently little published data on PB in CKD-5D across dialysis modalities. Methods This is a retrospective, single renal network study. All in-centre HD (MHD), peritoneal dialysis (PD) and home HD (HHD) pat...

Periodontitis, a chronic infectious disease, affects most of the population at one time or the other and its expression is a combination of hosts, microbial agents, and environmental factors. Extensive literature exists for the relationship between periodontal disease and diabetes mellitus, cardiovascular diseases, and adverse pregnancy outcomes. Only a few studies performed in a limited number of patients have reported peri-odontal health status in chronic renal failure patients. Hence, the aim of the present study is to assess and compare the periodontal status of patients with chronic renal failure undergoing dialysis, predialysis with systemically healthy individuals. A total of 90 patients were divided into three groups. Group I: 30 renal dialysis patients. Group II: 30 predialysis patients. Control group comprised 30 systemically healthy patients who formed group III. Periodontal examination was carried out using oral hygiene index-simplified (OHI-S), plaque index (PI), gingival index (GI), probing depth, and clinical attachment loss. The results of the study showed that the periodontal status of patients with chronic renal failure undergoing dialysis (dialysis group) and patients with chronic renal failure not undergoing renal dialysis (predialysis) when compared with systemically healthy subjects showed significantly higher mean scores of OHI-S, PI, and clinical attachment loss. Thus, patients with chronic renal failure showed poor oral hygiene and higher prevalence of periodontal disease. The dental community's awareness of implications of poor health within chronic renal failure patients should be elevated.

To assess the impact of renal impairment on pomalidomide exposure, a population pharmacokinetics (PPK model of pomalidomide in rrMM patients with various degrees of impaired renal function was developed. Intensive and sparse pomalidomide concentration data collected from two clinical studies in rrMM patients with normal renal function, moderately impaired renal function, severely impaired renal function not requiring dialysis, and with severely impaired renal function requiring dialysis were pooled over the dose range of 2 to 4 mg, to assess specifically the influence of the impaired renal function as a categorical variable and a continuous variable on pomalidomide clearance and plasma exposure. In addition, pomalidomide

To examine market competition and facility characteristics that can be related to technical efficiency in the production of multiple dialysis outputs from the perspective of the industrial organization model. Freestanding dialysis facilities that operated in 1997 submitted cost report fonns to the Health Care Financing Administration (HCFA), and offered all three outputs--outpatient dialysis, dialysis training, and home program dialysis. The Independent Renal Facility Cost Report Data file (IRFCRD) from HCFA was utilized to obtain information on output and input variables and market and facility features for 791 multiple-output facilities. Information regarding population characteristics was obtained from the Area Resources File. Cross-sectional data for the year 1997 were utilized to obtain facility-specific technical efficiency scores estimated through Data Envelopment Analysis (DEA). A binary variable of efficiency status was then regressed against its market and facility characteristics and control factors in a multivariate logistic regression analysis. The majority of the facilities in the sample are functioning technically inefficiently. Neither the intensity of market competition nor a policy of dialyzer reuse has a significant effect on the facilities' efficiency. Technical efficiency is significantly associated, however, with type of ownership, with the interaction between the market concentration of for-profits and ownership type, and with affiliations with chains of different sizes. Nonprofit and government-owned Facilities are more likely than their for-profit counterparts to become inefficient producers of renal dialysis outputs. On the other hand, that relationship between ownership form and efficiency is reversed as the market concentration of for-profits in a given market increases. Facilities that are members of large chains are more likely to be technically inefficient. Facilities do not appear to benefit from joint production of a variety of

Renal cell carcinoma (RCC) is more common in renal transplant and dialysis patients than the general population. However, RCC in transplanted kidneys is rare, and treatment has previously consisted of nephrectomy with a return to dialysis. There has been recent interest in nephron-sparing procedures as a treatment option for RCC in allograft kidneys in an effort to retain allograft function. Four patients with RCC in allograft kidneys were treated with nephrectomy, partial nephrectomy, or radiofrequency ablation. All of the patients are without evidence of recurrence of RCC after treatment. We found nephron-sparing procedures to be reasonable initial options in managing incidental RCCs diagnosed in functioning allografts to maintain an improved quality of life and avoid immediate dialysis compared with radical nephrectomy of a functioning allograft. However, in non-functioning renal allografts, radical nephrectomy may allow for a higher chance of cure without the loss of transplant function. Consequently, radical nephrectomy should be utilized whenever the allograft is non-functioning and the patient's surgical risk is not prohibitive. © 2013 John Wiley & Sons A/S.

2002-01-01

Objective: To determine the prevalence of renal failure in children requiring renal replacement therapy (RRT), the types of RRT being performed, problems encountered during the procedure and the outcome of the RRT in pediatric age group. Design: It was a retrospective study on pediatric patients with renal failure undergoing RRT. Place and Duration of Study: The study was carried out at National Institute of Child Health (N. I. C. H) covering a period of four years. Subjects and Methods: The study included all pediatric patients of acute renal failure, chronic renal failure and end stage renal disease who underwent RRT at N. I. C. H. Results: 17% of the patients with renal disease came in renal failure. A total of 65. 04 % patients received RT. Out of these, 84.7% underwent peritoneal dialysis (PD) while 15.3 % required hemodialysis and 2 were successfully transplanted. High cost of the RRT was the most commonly encountered problem during the procedure. Peritonitis was the commonest complication faced during the peritoneal dialysis while hypotension and complications related to vascular access were commonest during hemodialysis. About 50% of the patients undergoing peritoneal dialysis were left with persistent renal impairment while hemodialysis revealed a mortality of 37%. The two transplanted patients were doing well. Conclusion: The study showed that renal failure was a fairly common problem in pediatric age group and the prospects of successful RRT in Pakistan were quite high with a little effort on the part of medical professionals along with some financial assistance from the affluent of the country.

Ethics and Rationing Access to Dialysis in Resource-Limited Settings: The Consequences of Refusing a Renal Transplant in the South African State Sector.

Science.gov (United States)

Etheredge, Harriet; Paget, Graham

2015-12-01

Resource constraints in developing countries compel policy makers to ration the provision of healthcare services. This article examines one such set of Guidelines: A patient dialysing in the state sector in South Africa may not refuse renal transplantation when a kidney becomes available. Refusal of transplantation can lead to exclusion from the state-funded dialysis programme. This Guideline is legally acceptable as related to Constitutional stipulations which allow for rationing healthcare resources in South Africa. Evaluating the ethical merit of the Guideline, and exploring the ethical dilemma it poses, proves a more complex task. We examine the actions of healthcare professionals as constrained by the Guideline. From a best interests framework, we argue that in these circumstances directing patient decision making (pressurising a patient to undergo renal transplantation) is not necessarily unethical or unacceptably paternalistic. We then scrutinise the guideline itself through several different ethical 'lenses'. Here, we argue that bioethics does not provide a definitive answer as to the moral merit of rationing dialysis under these circumstances, however it can be considered just in this context. We conclude by examining a potential pitfall of the Guideline: Unwilling transplant recipients may not comply with immunosuppressive medication, which raises questions for policies based on resource management and rationing. © 2014 John Wiley & Sons Ltd.

Conclusion: Trace elements status in chronic kidney diseases patients is influenced by a renal function residual, size and dialyzer membrane surface. The water nature also is used for dialysis fluid preparation and composition. Trace elements in ESRD patients differed from healthy individuals. So this issue requires accurate studies on trace elements clinical aspects in ESRD patients.

Alterations of erythrocyte rheology and cellular susceptibility in end stage renal disease: Effects of peritoneal dialysis.

Full Text Available In this study, we investigated the effects of peritoneal dialysis on hemorheological and hematological parameters and their relations with oxidant and antioxidant status of uremic patients. Hemorheological parameters (erythrocyte deformability, erythrocyte aggregation, osmotic deformability, blood and plasma viscosity were measured in patients with renal insufficiency undergoing peritoneal dialysis (PD and volunteers. Erythrocyte deformability, osmotic deformability and aggregation in both autologous plasma and 3% dextran 70 were measured by laser diffraction ektacytometry. Enzyme activities of glutathione peroxidase, superoxide dismutase and catalase were studied in erythrocytes; lipid peroxidation was studied by measuring the amount of malondialdehyde in both erythrocytes and plasma samples. Blood viscosity at native hematocrit was significantly lower in PD patients at all measured shear rates compared to controls, but it was high in PD patients at corrected (45% hematocrit. Erythrocyte deformability did not show any difference between the two groups. Osmotic deformability was significantly lower in PD patients compared to controls. Aggregation index values were significantly high in PD patients in plasma Catalase and glutathione peroxidase activities in erythrocytes were decreased in PD patients whereas superoxide dismutase activity was increased compared to controls. Malondialdehyde was significantly increased in erythrocytes and plasma samples of PD patients which also shows correlations with aggregation parameters. It has been concluded that erythrocytes in PD patients are more prone to aggregation and this tendency could be influenced by lipid peroxidation activity in patient's plasma. These results imply that uremic conditions, loss of plasma proteins and an increased risk of oxidative stress because of decreasing levels of antioxidant enzymes affect erythrocyte rheology during peritoneal dialysis. This level of distortion may have

Latinos in the U.S. are almost twice as likely to progress to End Stage Renal disease (ESRD) compared to non-Latino whites. Patients with ESRD on dialysis experience high morbidity, pre-mature mortality and receive intensive procedures at the end of life (EOL). This study explores intensive procedure preferences at the EOL in older Latino adults. Seventy-three community-dwelling Spanish- and English-Speaking Latinos over the age of 60 with and without ESRD participated in this study. Those without ESRD (n = 47) participated in one of five focus group sessions, and those with ESRD on dialysis (n = 26) participated in one-on-one semi-structured interviews. Focus group and individual participants answered questions regarding intensive procedures at the EOL. Recurring themes were identified using standard qualitative content-analysis methods. Participants also completed a brief survey that included demographics, language preference, health insurance coverage, co-morbidities, Emergency Department visits and functional limitations. The majority of participants were of Mexican origin with mean age of 70, and there were more female participants in the non-ESRD group, compared to the ESRD dialysis dependent group. The dialysis group reported a higher number of co-morbidities and functional limitations. Nearly 69% of those in the dialysis group reported one or more emergency department visits in the past year, compared to 38% in the non-ESRD group. Primary themes centered on 1) The acceptability of a "natural" versus "invasive" procedure 2) Cultural traditions and family involvement 3) Level of trust in physicians and autonomy in decision-making. Our results highlight the need for improved patient- and family-centered approaches to better understand intensive procedure preferences at the EOL in this underserved population of older adults.

2003-01-01

The national incidence of and factors associated with total hip arthroplasty (THA) in chronic dialysis patients has never been reported. We therefore performed an historical cohort study of 375,857 chronic dialysis patients listed in the 2000 United States Renal Data System between 1 April 1995 and 31 December 1999 and followed-up until 14 May 2000. Primary outcomes were associations with hospitalizations for a primary discharge code of THA (ICD9 procedure code 81.51x) after initiation of dialysis. Dialysis patients had a cumulative incidence of THA of 35 episodes/10,000 person-years, compared to 5.3/10,000 in the general population. The leading indication for THA was osteoarthritis of the hip and pelvis (58% of cases). However, the strongest risk factor for THA in dialysis patients was end-stage renal disease (ESRD) due to systemic lupus erythematosus (SLE, adjusted rate ratio (ARR), 6.80, 95% CI 4.62-10.03, in whom avascular necrosis of the hip was the most common indication, 68.4%). The database did not include information on use of corticosteroids. Diabetic recipients were significantly less likely to receive THA, as were males, and African Americans. Mortality after THA was 0.25% at thirty days and 30% at three years, not significantly different from the expected mortality of dialysis, adjusted for comorbidity. The most common indication for THA in dialysis patients is osteoarthritis of the hip, similar to the general population. Patients with SLE are more likely to receive THA which is well tolerated and not associated with increased mortality in this population, perhaps reflecting selection bias due to appropriate screening for this elective procedure.

Full Text Available Peritoneal dialysis (PD is a well-established modality for treatment of patients with end-stage renal disease, giving excellent patient and technique survival rates. In Saudi Arabia, data collected by the Saudi Center for Organ Transplantation showed that in 2008, patients on PD accounted for a mere 4.8% of total patients on renal replacement therapy, including hemodialysis and renal transplantation. This study was conducted to identify the characteristics of membrane per-meability in the Saudi population and to assess the role of various factors affecting solute transport across the peritoneal membrane. We followed up a total of 52 patients on Continuous Ambulatory Peritoneal Dialysis (CAPD as well as Automated Peritoneal Dialysis (APD, being treated in the PD unit of the King Khalid University Hospital, Riyadh. There were 30 female and 22 male patients; 14 patients were using CAPD while 38 patients were on APD. The mean age of the patients was 50.5 years, with a range of 14-86 years. The average body mass index (BMI was 27.1 kg/m 2 and the mean body surface area (BSA of the study patients was 1.71 m 2 . A standardized PET test was performed on all patients, 4-6 weeks after initiation of regular PD. The Kt/V and creatinine clearance measured 6-8 weeks after initiation of dialysis were 1.96 and 56.59 L/week, respectively. Residual renal function was assessed on the basis of daily urine output, using 24-hour urine collection. The mean serum urea con-centration was 16.91 mmol/L and mean serum creatinine was 702 μmol/L. According to the Peritoneal Equiliberation Test (PET, 8% of the subjects belonged to the high trans-porter category, 44% patients belonged to the high-average transport group, 46% to the low-average category and 2% came in the low transporter category. Our study suggests that the patient characteristics and demographic para-meters seen in the Saudi population are comparable to those seen in other studies from the Middle East and

To explore the natural history of critically ill patients with acute renal failure due to acute tubular necrosis, we evaluated 256 patients enrolled in the placebo arm of a randomized clinical trial. Death and the composite outcome, death or the provision of dialysis, were determined with follow-up to 60 d. The relative risks (RR) and 95% confidence intervals (95% CI) associated with routinely available demographic, clinical, and laboratory variables were estimated using proportional hazards regression. Ninety-three (36%) deaths were documented; an additional 52 (20%) patients who survived received dialysis. Predictors of mortality included male gender (RR, 2.01; 95% CI, 1.21 to 3.36), oliguria (RR, 2.25; 95% CI, 1.43 to 3.55), mechanical ventilation (RR, 1.86; 95% CI, 1.18 to 2.93), acute myocardial infarction (RR, 3.14; 95% CI, 1.85 to 5.31), acute stroke or seizure (RR, 3.08; 95% CI, 1.56 to 6.06), chronic immunosuppression (RR, 2.37; 95% CI, 1.16 to 4.88), hyperbilirubinemia (RR, 1.06; 95% CI, 1.03 to 1.08 per 1 mg/dl increase in total bilirubin) and metabolic acidosis (RR, 0.95; 95% CI, 0.90 to 0.99 per 1 mEq/L increase in serum bicarbonate concentration). Predictors of death or the provision of dialysis were oliguria (RR, 5.95; 95% CI, 3.96 to 8.95), mechanical ventilation (RR, 1.53; 95% CI, 1.07 to 2.21), acute myocardial infarction (RR, 1.95; 95% CI, 1.24 to 3.07), arrhythmia (RR, 1.51; 95% CI, 1.04 to 2.19), and hypoalbuminemia (RR, 0.56; 95% CI, 0.42 to 0.74 per 1 g/dl increase in serum albumin concentration). Neither mortality nor the provision of dialysis was related to patient age. These observations can be used to estimate risk early in the course of acute tubular necrosis. Furthermore, these and related models may be used to adjust for case-mix variation in quality improvement efforts, and to objectively stratify patients in future intervention trials aimed at favorably altering the course of hospital-acquired acute renal failure.

Features of Mineral Metabolism and Parathyroid Glands Functioning in Chronic Renal Disease

Full Text Available The calcium phosphoric metabolism was analyzed depending on the severity of renal functioning disorders. Chronic renal disease is known to be associated with impaired mineral metabolism in terms of hypocalcaemia, hyperphosphatemia and enhanced level of Ca × P product that aggravates in chronic renal failure progression. The majority of patients with nephropathy have parathyroid hormone concentration to be different from target one recommended by NKF-K/DOQI (2003, at that secondary hyperparathyroidism prevails on pre-dialysis stage of chronic renal disease, the relative hypoparathyroidism is common among the patients received dialysis.

Performance measures for a dialysis setting.

Gu, Xiuzhu; Itoh, Kenji

2018-03-01

This study from Japan extracted performance measures for dialysis unit management and investigated their characteristics from professional views. Two surveys were conducted using self-administered questionnaires, in which dialysis managers/staff were asked to rate the usefulness of 44 performance indicators. A total of 255 managers and 2,097 staff responded. Eight performance measures were elicited from dialysis manager and staff responses: these were safety, operational efficiency, quality of working life, financial effectiveness, employee development, mortality, patient/employee satisfaction and patient-centred health care. These performance measures were almost compatible with those extracted in overall healthcare settings in a previous study. Internal reliability, content and construct validity of the performance measures for the dialysis setting were ensured to some extent. As a general trend, both dialysis managers and staff perceived performance measures as highly useful, especially for safety, mortality, operational efficiency and patient/employee satisfaction, but showed relatively low concerns for patient-centred health care and employee development. However, dialysis managers' usefulness perceptions were significantly higher than staff. Important guidelines for designing a holistic hospital/clinic management system were yielded. Performance measures must be balanced for outcomes and performance shaping factors (PSF); a common set of performance measures could be applied to all the healthcare settings, although performance indicators of each measure should be composed based on the application field and setting; in addition, sound causal relationships between PSF and outcome measures/indicators should be explored for further improvement. © 2017 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Renal failure commonly complicates multiple myeloma (MM) and is associated with reduced survival. It is not clear whether auto-SCT results in improved renal function or attainment of independence from dialysis in patients with advanced renal impairment due to MM. We conducted a retrospective cohort study of all patients who underwent auto-SCT for MM complicated by advanced renal failure at our institution over a 10-year period (2000-2010). We aimed to assess the association between auto-SCT and renal outcome in patients with serum creatinine (SCr) over 3 mg/dL, attributable to MM, including those who were dialysis dependent. Thirty patients (2.8% of all auto-SCT patients) met inclusion criteria. Fourteen of 15 patients who were dialysis dependent before auto-SCT remained dialysis dependent in the long term despite hematological response (HR). Of the remaining 15 patients with SCr >3 mg/dL, an improvement in glomerular filtration rate (GFR) from 15 to 19.4 mL/min/1.73 m(2) was noted post auto-SCT (P=0.035); however, neither HR post auto-SCT or pre-existing renal function were independently associated with renal outcome. Auto-SCT was not associated with independence from dialysis in patients with renal failure due to MM at our institution. Although auto-SCT was associated with an improvement in GFR in patients with SCr >3 mg/dL, this improvement was not related to HR.

relationship between outcome and dialysis dose needs to be better defined. Data relating adequacy of dialysis to outcome in a pediatric population is not available. In dialysis therapy, the Risk/Dose (R/D) function does not bear a linear relationship. This together with a lack of proof equating peritoneal to renal clearance lends some uncertainty to the validity of the recommendation that there is a linear and constant decrease in RR for std (Kt/V) [equivalent standardized Kt/V calculated from average predialysis BUN for any frequency and/or combination of intermittent and continuous dialysis ref] up to 2.3 as reported in the CANUSA study. Due to the complex nature of this problem it may be prudent to undertake a multi-center trial with std (Kt/V) prospectively randomized to either 2.0 or 2.4. This would provide a reliable database to evaluate the R/D function over this critical range of normalized peritoneal urea clearance. Likewise in PD, the postulated linearity between dialysis dose and outcome needs to be studied in a prospective randomized manner. The amount of dialysis dose required for malnourished patients, diabetic and pediatric patients needs to be better defined. The role of aggressive dialysis in reversing malnutrition needs to be studied and studies need to be done to identify the most scientific use of V in malnourished patients. Justification of a healthy start/incremental dialysis based on outcome measures needs to be established and it's cost effectiveness validated by clinical trials. Again, a prospective randomized controlled trial comparing incremental dialysis with dietary protein restriction in patients with GFR < or = 10.5 ml/min/1.73 m2 with properly defined outcome measures like morbidity, mortality, decline of GFR and quality of life needs to be conducted. Comparisons of incremental hemodialysis and incremental peritoneal dialysis need to be made especially with regard to technique survival and preservation of residual renal function (RRF). (ABSTR

We aimed to describe survival in European pediatric dialysis patients and compare the differential mortality risk between patients starting on hemodialysis (HD) and peritoneal dialysis (PD). Data for 6473 patients under 19 years of age or younger were extracted from the European Society of Pediat...... dialysis (HD/PD adjusted HR 6.55, 95% CI 2.35–18.28, PSM HR 2.93, 95% CI 1.04–8.23). Because unmeasured case-mix differences and selection bias may explain the higher mortality risk in the HD population, these results should be interpreted with caution....

Clinical evaluation of novel methods to determine dialysis parameters using conductivity cells

During the last two decades an ongoing discussion about the necessary dose of dialysis brought the result that the urea based Kt/V value is significantly correlated to morbidity of the end stage renal disease (ESRD) patients. Even if it is not completely accepted, it seems to be more and more agreement of the nephrological community that for good dialysis practice Kt/V should be kept above 1.2 to 1.3 in the usual 3X4 hours per week dialysis schedule for patients without own residual clearance...

Introduction: Uric acid is one of the most significant uremic toxins accumulating in chronic renal failure patients treated with standard dialysis. Its clearance has not any exact relation with urea and creatinine clearance. Objectives: The aim of this study was to investigate the relationship between adequacy of dialysis and serum level of uric acid in dialysis patients of some dialysis centers in Iran. Patients and Methods: In this study 1271 hemodialysis patients who have been treated for more than 3 months were evaluated. Their information and examinations from their files in all over the country were gathered and analyzed using SPSS versin18.0. Results: In this study, a significant relationship between dialysis duration and serum level of uric acid was not detected, however, a significant relationship between patients Kt/V and uric acid (R=0.43, P =0.029) was seen. Patients who had higher adequacy of dialysis had a higher level of plasma uric acid. Conclusion: For better controlling of plasma uric acid level of hemodialysis patients, increasing of the adequacy of dialysis or its duration is not effective. Other modalities of decreasing of serum uric acid like, changing diet or lifestyle or medical therapy may be necessary.

Full Text Available The objective of the audit is to determine the prevalence of malnutrition in maintenance peritoneal dialysis (MPD patients in the Top End of the Northern Territory, using the modified Subjective Global Assessment (SGA tool. Methods: The audit was conducted in an outpatients setting. Approximately 75% of PD patients in the Top End Renal service are represented by Aboriginal and Torres Strait Island people. The study population was MPD patients in the Top End Renal Service (TERS of the Northern Territory, from January 1st 2010 to December 31st 2010. Results were compared to malnutrition rates found in the 2008/09 the audit of MPD patients in the TERS. The SGA’s were performed by the renal Dietitian as part of the standard dietetic support of MPD patients. SGA scores were collected from patient medical charts. Results: Patients were classified into one of three categories, based on their SGA score (A Well-nourished; (B Mild- Moderate Malnutrition, (C Severe malnutrition. Malnutrition (B or C was detected in 10% of PD patients, compared to the 2008/09 audit where 76% of MPD patients had some degree of malnutrition. Summary: These results were much lower than malnutrition rates (76% in the MPD patients audited in 2008/09. A number of factors affecting the PD service after the 2008/09 audit could explain the decrease in malnutrition rates including the implementation of free oral nutrition supplements to MPD patients, development of service wide culturally appropriate education resources used in the pre-dialysis and dialysis stage. Future research into the correlation between improved peritonitis rates and decreased malnutrition rates in the population are warranted.

Full Text Available Depression is a common morbidity seen in chronic renal failure patients but it is often underdiagnosed and undertreated. Here we present a 36-year-old male dialysis patient who had undiagnosed severe depression and attempted to commit suicide with overconsumption of fruits. Fortunately, he was saved with emergent dialysis treatment and was referred to a psychiatry clinic for treatment and observation. In the light of this case we want to point out that diagnosing and treating psychiatric problems of dialysis patients is of vital importance to prevent suicides and also to improve quality of life.

Role of telehealth in renal replacement therapy education.

Malkina, Anna; Tuot, Delphine S

2018-03-01

The prevalence of end-stage renal disease is rising in the United States, which bears high financial and public health burden. The most common modality of renal replacement therapy (RRT) in the United States is in-center hemodialysis. Many patients report lack of comprehensive and timely education about their treatment options, which may preclude them from participating in home-based dialysis therapies and kidney transplantation evaluation. While RRT education has traditionally been provided in-person, the rise of telehealth has afforded new opportunities to improve upon the status quo. For example, technology-augmented RRT education has recently been implemented into telehealth nephrology clinics, informational websites and mobile applications maintained by professional organizations, patient-driven forums on social media, and multimodality programs. The benefits of technology in RRT education are increased access for geographically isolated and/or medically frail patients, versatility of content delivery, information repetition to enhance knowledge retention, and interpersonal connection for educational content and emotional support. Challenges center around privacy and accuracy of information sharing, in addition to differential access to technology due to age and socioeconomic status. A review of available scholarly and social media resources suggests that technology-aided delivery of education about treatment options for end-stage renal disease provides an important alternative and/or supplemental resource for patients and families. © 2018 Wiley Periodicals, Inc.

Effect of water deionisers on 'fracturing osteodystrophy' and dialysis encephalopathy in Plymouth.

Science.gov (United States)

Leather, H M; Lewin, I G; Calder, E; Braybrooke, J; Cox, R R

1981-01-01

In the Plymouth area, 95 patients with end-stage renal failure have undergone haemodialysis for 6 months or longer. Of the 47 patients beginning dialysis between 1967 and 1973, when water deionisers were not used routinely, a bone disease with multiple fractures, 'fracturing osteodystrophy', occurred in 18 patients and dialysis encephalopathy in 10. Of the 48 patients first dialysing between 1974 and 1979, when water deionisers used commonly, fracturing osteodystrophy occurred in only one and dialysis encephalopathy also in only one. Duration of dialysis without a water deioniser appeared to be the most important factor in the development of these two conditions. The use of water deionisers usually led to healing of fractures in patients with fracturing osteodystrophy and also led to improvement in 4 of the 11 patients with dialysis encephalopathy. Neither condition has occurred in any patient using a water deioniser from the first dialysis. Water deionisers, therefore, appeared to be effective in both the treatment and prevention of fracturing osteodystrophy and dialysis encephalopathy.

Improving Distress in Dialysis (iDiD): A tailored CBT self-management treatment for patients undergoing dialysis.

2016-12-01

There is significant psychological distress in adults with end-stage kidney disease (ESKD). However, psychological treatments tailored to address the unique challenges of kidney failure are absent. We identified psychological correlates of distress in ESKD to develop a cognitive-behavioural therapy (CBT) treatment protocol that integrates the mental health needs of patients alongside their illness self-management demands. Studies which examined relationships between distress and psychological factors that apply in the context of ESKD including: health threats, cognitive illness representations and illness management behaviours were narratively reviewed. Review findings were translated into a CBT formulation model to inform the content of a renal-specific seven session CBT treatment protocol, which was commented on and refined by patient representatives. Health threats related to distress were grouped into four themes including: acute ESKD events, loss of role, uncertainty and illness self-management. Having pessimistic illness and treatment perceptions were associated with elevated distress. Non-adherence and avoidance behaviours were related to feelings of distress, whereas cognitive reappraisal, acceptance, social support and assertiveness were associated with less distress. The dialysis-specific CBT formulation identifies the importance of targeting ESKD-specific correlates of distress to allow the delivery of integrated mental and physical health care. The 'Improving Distress in Dialysis (iDiD)' treatment protocol now requires further evaluation in terms of content, feasibility and potential efficacy. © 2016 European Dialysis and Transplant Nurses Association/European Renal Care Association.

In a number of countries, reimbursement to hospitals providing renal dialysis services is set according to a fixed tariff. While the cost of maintenance dialysis and transplant surgery are amenable to a system of fixed tariffs, patients with established renal failure commonly present with comorbid conditions that can lead to variations in the need for hospitalization beyond the provision of renal replacement therapy. Patient-level cost data for incident renal replacement therapy patients in England were obtained as a result of linkage of the Hospital Episodes Statistics dataset to UK Renal Registry data. Regression models were developed to explore variations in hospital costs in relation to treatment modality, number of years on treatment and factors such as age and comorbidities. The final models were then used to predict annual costs for patients with different sets of characteristics. Excluding the cost of renal replacement therapy itself, inpatient costs generally decreased with number of years on treatment for haemodialysis and transplant patients, whereas costs for patients receiving peritoneal dialysis remained constant. Diabetes was associated with higher mean annual costs for all patients irrespective of treatment modality and hospital setting. Age did not have a consistent effect on costs. Combining predicted hospital costs with the fixed costs of renal replacement therapy showed that the total cost differential for a patient continuing on dialysis rather than receiving a transplant is considerable following the first year of renal replacement therapy, thus reinforcing the longer-term economic advantage of transplantation over dialysis for the health service. © The Author 2015.

Simoni, J M; Asarnow, J R; Munford, P R; Koprowski, C M; Belin, T R; Salusky, I B

1997-10-01

Among 23 pediatric renal dialysis patients, we obtained self-reported assessments of psychological adjustment and biochemical and subjective ratings of adherence. Findings indicate elevated levels of depressive symptoms and substantial nonadherence. Depressive symptoms were associated with higher levels of hopelessness, more negative self-perceptions, and more depressogenic attributional style. The psychological adjustment measures did not significantly correlate with adherence. Nonsignificant associations among different measures of adherence underscore its multifaceted nature. Implications for monitoring the adjustment of children on dialysis, assessing adherence, and future research are discussed.

Medication burden in CKD-5D: impact of dialysis modality and setting.

Parker, Kathrine; Nikam, Milind; Jayanti, Anuradha; Mitra, Sandip

2014-12-01

Medication adherence is thought to be around 50% in the general and dialysis population. Reducing the pill burden (PB) reduces regime complexity and can improve adherence. Increased adherence should lead to improvement in treatment outcomes and patient quality of life. There is currently little published data on PB in CKD-5D across dialysis modalities. This is a retrospective, single renal network study. All in-centre HD (MHD), peritoneal dialysis (PD) and home HD (HHD) patients were identified in the Greater Manchester East sector renal network. Information collected included age, sex, comorbidities, daily PB, dialysis vintage and adequacy. Data were retrieved from a customized renal database, clinic and discharge letters with cross validation from the general practitioner when needed. Two hundred and thirty-six prevalent dialysis patients were studied. HHD patients had a significantly lower PB (11 ± 7 pills/day) compared with PD and MHD (16 ± 7 pills/day). The HHD patients required fewer BP medications to meet the recommended target. HD setting was the only significant factor for reducing PB. For home therapies (HHD versus PD), weekly Kt/v and serum phosphate were significant factors influencing PB. When comparing all modalities, OR of PB ≥ 15/day for MHD versus HHD was 3.9 and PD versus HHD was 4.9. The influence of HHD is dominant above factors such as comorbidities or clinical variables in reducing PB for MHD. Higher clearances achieved by HHD could explain differences in PB with PD. This is the first comparative study of PB across all dialysis modalities and factors that influence it. The PB advantage in HHD may result in greater adherence and might contribute to the outcome benefit often seen with this modality. Higher clearances achieved by HHD could explain differences in PB with PD but the precise reasons for lower PB remain speculative and deserve further research in larger settings.

Determinants of Adherence to Living on Dialysis for Mexican Americans

Full Text Available This study explores perceptions that affect adherence behaviors among Mexican Americans living with dialysis. In-depth narrative interviews were conducted with 15 Mexican Americans with end-stage renal disease (ESRD living on dialysis, 15 family members, and 6 health care personnel who provided care to them. Four themes emerged: (a positive influences to adherence, (b obstacles to adherence, (c daily activity losses, and (d fears about living with dialysis. From the findings, the perceptions given for non-adherence with the dialysis regimen ranged from denial of the condition, lack of pre-education, to cultural factors. Those given for adherence included prolonged life, family, and hope of getting a transplant. Health care providers were the reminder to adhere. Several cultural factors influenced their adherence perceptions. Strategies to enhance adherence behaviors should focus on knowledge about dialysis, use of the collective efficacy of the family, and the inclusion of cultural values.

Full Text Available Exertional rhabdomyolysis is sequela that is occasionally seen after strenuous exercise. The progression to compartment syndrome or renal failure is a rare complication that requires prompt recognition and treatment to prevent morbidity (Giannoglou et al. 2007. We present a case of a 22-year-old college football player who presented to the emergency department (ED after a typical leg workout as part of his weight conditioning. He was found to have rhabdomyolysis with evidence of renal insufficiency. His condition progressed to bilateral compartment syndrome and renal failure requiring dialysis. After bilateral fasciotomies were performed he had resolution of his compartment syndrome. He continued to be dialysis dependent and had no return of his renal function at discharge 12 days after admission.

Daily dialysis has shown excellent clinical results because a higher frequency of dialysis is more physiological. Different methods have been described to calculate dialysis dose which take into consideration change in frequency. The aim of this study was to calculate all dialysis dose possibilities and evaluate the better and practical options. Eight patients, 6 males and 2 females, on standard 4 to 5 hours thrice weekly on-line hemodiafiltration (S-OL-HDF) were switched to daily on-line hemodiafiltration (D-OL-HDF) 2 to 2.5 hours six times per week. Dialysis parameters were identical during both periods and only frequency and dialysis time of each session were changed. Time average concentration (TAC), time average deviation (TAD), normalized protein catabolic rate (nPCR), Kt/V, equilibrated Kt/V (eKt/V), equivalent renal urea clearance (EKR), standard Kt/V (stdKt/V), urea reduction ratio (URR), hemodialysis product and time off dialysis were measured. Daily on-line hemodiafiltration was well accepted and tolerated. Patients maintained the same TAC although TAD decreased from 9.7 +/- 2 in baseline to a 6.2 +/- 2 mg/dl after six months, p time off dialysis was reduced to half. Dialysis frequency is an important urea kinetic parameter which there are to take in consideration. It's necessary to use EKR, stdKt/V or weekly URR to calculate dialysis dose for an adequate comparison between different frequency dialysis schedules.

Remote Patient Management for Home Dialysis Patients

Full Text Available Remote patient management (RPM offers renal health care providers and patients with end-stage kidney disease opportunities to embrace home dialysis therapies with greater confidence and the potential to obtain better clinical outcomes. Barriers and evidence required to increase adoption of RPM by the nephrology community need to be clearly defined. Ten health care providers from specialties including nephrology, cardiology, pediatrics, epidemiology, nursing, and health informatics with experience in home dialysis and the use of RPM systems gathered in Vienna, Austria to discuss opportunities for, barriers to, and system requirements of RPM as it applies to the home dialysis patient. Although improved outcomes and cost-effectiveness of RPM have been demonstrated in patients with diabetes mellitus and heart disease, only observational data on RPM have been gathered in patients on dialysis. The current review focused on RPM systems currently in use, on how RPM should be integrated into future care, and on the evidence needed for optimized implementation to improve clinical and economic outcomes. Randomized controlled trials and/or large observational studies could inform the most effective and economical use of RPM in home dialysis. These studies are needed to establish the value of existing and/or future RPM models among patients, policy makers, and health care providers.

According to the 2004 US Renal Data System's annual report, the incidence rate of chronic renal failure in Taiwan increased from 120 to 352 per million populations between 1990 and 2003. This incidence rate is the highest in the world. The prevalence rate, which ranks number two in the world (Japan ranks number one), also increased from 384 to 1630 per million populations. Based on 2005 Taiwan national statistics, there were 52,958 end-stage renal disease (ESRD) patients receiving routine dialysis treatment. This number, which comprised less than 0.2% of the total population and consumed $2.6 billion New Taiwan dollars, was more than 6.12% of the total annual spending of national health insurance during 2005. Dialysis expenditures for patients with ESRD rank the highest among all major injuries (traumas) and diseases. This article identifies and discusses the risk factors associated with consumption of medical resources during dialysis. Instead of using reimbursement data to estimate cost, as seen in previous studies, this study uses cost data within organizations and focuses on evaluating and predicting the resource consumption pattern for dialysis patients with different risk factors. Multiple regression analysis was used to identify 23 risk factors for routine dialysis patients. Of these risk factors, six were associated with the increase of dialysis cost: age (i.e. 75 years old and older), liver function disorder, hypertension, bile-duct disorder, cancer and high blood lipids. Patients with liver function disorder incurred much higher costs for injection medication and supplies. Hypertensive patients incurred higher costs for injection medication, supplies and oral medication. Patients with bile-duct disorder incurred a significant difference in check-up costs (i.e. costs were higher for those aged 75 years and older than those who were younger than 30 years of age). Cancer patients also incurred significant differences in cost of medical supplies. Patients

Progressive and generalized loss of muscle mass (muscle wasting) is a frequent complication in dialysis patients. Common uremic signs and symptoms such as insulin-resistance, increase in glucocorticoid activity, metabolic acidosis, malnutrition, inflammation and dialysis per se contribute to muscle wasting by modulating proteolytic intracellular mechanisms (ubiquitin-proteasome system, activation of caspase-3 and IGF-1/PI3K/Akt pathway). Since muscle wasting is associated with an increase in mortality, bone fractures and worsening in life quality, a prompt and personalised diagnostic and therapeutic approach seems to be essential in dialysis patients. At present, nuclear magnetic resonance (NMR), computed tomography (CT), dual-energy x-ray absorptiometry (DXA), impedance analysis, bioelectric impedance analysis (BIA) and anthropometric measurements are the main tools used to assess skeletal muscle mass. Aerobic and anaerobic training programmes and treatment of uremic complications reduce muscle wasting and increase muscle strength in uremic patients. The present review analyses the most recent data about the physiopathology, diagnosis, therapy and future perspectives of treatment of muscle wasting in dialysis patients.

The purpose of this study was to evaluate the usefulness of labelled platelet scintigraphy in the differential diagnosis of a prolonged febrile syndrome (PFS) in patients on dialysis carrying a non-functioning renal allograft. We prospectively performed an indium-111 mercaptopyridine-labelled platelet scan on 91 patients (54 men, 37 women; mean age 39.6±12 years). The mean duration of PFS was 35 days (range 7-122). Forty-six of the 91 patients underwent steroid therapy (2- 10 mg/day). Platelet labelling was carried out following Thakur's method. Platelet scans were performed 48 h after reinjection of labelled platelets. The platelet uptake index (PUI) was calculated by dividing the cpm/pixel in the allograft ROI by cpm/pixel in a mirror background ROI. The final diagnosis of PFS was established depending on the outcome after treatment. In 61/91 patients the fever had an immunological origin because it disappeared after graft embolisation or transplantectomy. In 30/91 patients the PFS disappeared after antibiotic therapy (non-immunological origin). The PUI in patients with immunological PFS was 1.80±0.7, while in patients with non-immunological PFS it was 1.12±0.1 (P 111 In-labelled platelet scintigraphy can accurately predict an immunological PFS in patients on dialysis carrying a non-functioning renal allograft. Therapy with steroids could reduce the sensitivity of 111 In-labelled platelet scintigraphy in detecting immunological PFS. (orig.)

Investigation of a Rise in Obstetric Acute Renal Failure in the United States, 1999-2011.

2016-05-01

To estimate whether the reported increase in obstetric acute renal failure in the United States was attributable to a concurrent rise in postpartum hemorrhage, a change in other risk factors, or changes in the diagnosis of acute renal failure. We conducted a retrospective cohort study to quantify temporal trends in acute renal failure among 10,969,263 hospital deliveries in the United States from 1999 to 2011 using data from the Nationwide Inpatient Sample. Dialysis and maternal death were used as markers of severe acute renal failure. Logistic regression was used to determine whether changes in risk factors explained the temporal rise in acute renal failure. Obstetric acute renal failure rose from 2.4 to 6.3 per 10,000 deliveries between 1999-2001 and 2010-2011, a 10% yearly increase (95% confidence interval [CI] 8-11%) and adjustment for risk factors only partially explained the rise (adjusted yearly increase 6%, 95% CI 5-8%). The overall severity of acute renal failure decreased, although acute renal failure with dialysis rose from 0.27 to 0.36 per 10,000 deliveries (P for trend=.01), and acute renal failure associated with maternal death increased from 0.13 to 0.23 per 10,000 deliveries (P for trend=.01). The temporal increase in acute renal failure with dialysis was abolished by adjustment for chronic kidney disease and chronic hypertension. Changes in diagnosis or ascertainment have led to substantial increases in obstetric acute renal failure, whereas increases in chronic kidney disease and chronic hypertension among pregnant women have resulted in modest but significant increases in acute renal failure with dialysis.

Patients with a failed renal transplant.

Despite the advances in the care of recipients and in immunosuppression, long-term graft survival has experienced little improvement in the last 10 years. An important number of recipients present progressive loss of graft function and have to be readmitted on dialysis therapy. Before starting dialysis, these patients are re-exposed to the complications of chronic renal failure but there are no specific guidelines for their treatment. The Kidney Disease Quality Initiative Advisory Board clinical practice guidelines given for the non-transplant chronic kidney disease patients have been recommended for ameliorating their clinical situation and the rate of progression of graft failure. The time when dialysis has to be restarted and the type of dialysis procedure, hemodialysis or peritoneal dialysis, are under discusion. But there is no evidence about the superiority of either type of dialysis procedure. Systematic graft nephrectomy has been considered to improve the inflammatory status of the patients with a failed graft which could contribute to a worse control of some complications such as anemia and to the increased rates of cardiovascular mortality. As in the patients with primary end-stage renal disease, retransplantation is the best treatment for a patient with a failed graft. Due to the shortage of organs for transplantation the number of patients who are retransplanted has remained stable. Recurrent diseases such as glomerulonephritis, lyphoproliferative diseases, BK virus nephopathy and previous non-adherence to the treatment do not necessarily preclude retransplantation.

This paper is a report of a study conducted to examine self-reported adherence to a therapeutic regimen for continuous ambulatory peritoneal dialysis. Studies of patients' adherence during dialysis have primarily focused on haemodialysis and have frequently yielded inconsistent results, which are attributed to the inconsistent tools used to measure adherence. Levels of adherence to all four components of the therapeutic regimen (i.e. dietary and fluid restrictions, medication, and the dialysis regimen) among patients receiving peritoneal dialysis have not been examined, especially from a patient perspective. A total population sample was used. A cross-sectional survey was carried out by face-to-face interviews in 2005 in one renal clinic in Hong Kong. A total of 173 patients undergoing peritoneal dialysis (56% of the total population) participated in the study. Patients perceived themselves as more adherent to medication (83%; 95% confidence interval 77-88%) and dialysis (93%; 95% confidence interval 88-96%) prescriptions than to fluid (64%; 95% confidence interval 56-71%) and dietary (38%; 95% confidence interval 30-45%) restrictions. Those who were male, younger or had received dialysis for 1-3 years saw themselves as more non-adherent compared with other patients. Healthcare professionals should take cultural issues into consideration when setting dietary and fluid restriction guidelines. Additional attention and support are required for patients who identify themselves as more non-adherent. To help patients live with end-stage renal disease and its treatment, qualitative research is required to understand how they go through the dynamic process of adherence.

Full Text Available Background/Aim. Thanatophobia is an exaggerated, specific, structured fear of death. It appears in childhood and continues to grow over the years, and in the old age it is accompanied with nosophobia and other mental disorders. The aim of this study was to analyze thanatophobia in dialysed patients which was in the direct connection with a basic disorder, and the influence of this disorder on functioning and the quality of life of the patients on dialysis. Methods. In the study we examined 753 patients from the chronic program of haemodialysis in a period from 1999 to 2004. The patients were classified in two groups: 348 randomized patients with Balkan Endemic Nephropathy (BEN, and the control group (N18 of patients with terminal renal insufficiency, and other diagnoses (n = 405. Since the study was a comparative, cross-sectional one, the patients were tested by the appropriate questionnaires for anxiety, depression and general mental functioning. Statistical analysis was done by the standard descriptive and analytic statistic methods. Results. Based on socio-demographics data we revealed a highly significant difference regarding the place of living between the groups BEN and N18 (χ2 = 23.970; p < 0.01, the frequency of occurrence of renal comorbidity (χ2 = 23.970; p < 0.01, the frequency of family renal comorbidity in siblings (χ2 = 23.970; p < 0.01, and the frequency of migrationes (χ2 = 4.874; p < 0.01. According to psychiatry scales, the patients from the BEN group were significantly more anxious and depressive than those from the control group. Conclusion. The signs of thanatophobia were revealed in both examined groups, but significantly more in the patients with BEN than in those with other nephrologic diseases. Thanatophobia starts before dialysis, and dialysis structures it into fear of death which is in a direct connection with the basic disorder. This intensive fear may be connected with dementia and depression, but also with

Cardiovascular diseases are leading cause of death in patients with chronic renal failure. The aim of our study was to establish connection between levels of homocysteine and traditional and nontraditional risk factors for developing cardiovascular diseases in dialysis and pre dialysis patients. We included 33 pre dialysis (23 in stage three and 10 in stage four of chronic kidney disease) and 43 patients receiving hemodialysis longer than six months. Besides standard laboratory parameters, levels of homocysteine and blood pressure were measured in all patients. Glomerular filtration rate was measured in pre dialysis patients and dialysis quality parameters in dialysis patients. Homocysteine levels were elevated in all patients (19±5.42mmol/l). The connection between homocysteine levels and other cardiovascular diseases risk factors was not established in pre dialysis patients. In patients treated with hemodialysis we found negative correlation between homocysteine levels and patients' age (phomocysteine levels and length of dialysis (phomocysteine and anemia parameters (erythrocytes, hemoglobin), (pHomocysteine and LDL (and total cholesterol) were in negative correlation (pHomocysteine, as one of nontraditional cardiovascular diseases risk factors, is elevated in all patients with chronic renal failure and it's positive correlation with some other risk factors was found.

Given the public health challenge and burden of chronic kidney disease, the Italian Society of Nephrology (SIN) has compiled a national census of Renal Units (RU) existing in the twenty Italian regions related to the year 2004. An on-line questionnaire including 158 items explored structural and human resources, organization aspects, activities and epidemiological data in SIN, 2004. The census identified 363 public RU, 303 satellite Dialysis Centres (DC) and 295 private DC totalling 961 DC [16.4 per million population (pmp)]. The inpatient renal beds were 2742 (47 pmp). Renal and dialysis activity was performed by 3728 physicians (64 pmp), of whom 2964 (80%) were nephrologists. There was no permanent medical assistance in 41% of satellite DC. There were 1802 renal admissions pmp and 99 renal biopsies pmp. The management of acute renal failure (13 456 cases; 230 pmp) represented a relevant proportion of the activities conducted in public RU. In 2004 there were 9858 new cases of end-stage kidney disease requiring renal replacement therapy (RRT) (169 pmp). On 31 December 2004, 60 058 patients were on RRT (1027 pmp), 43 293 of which (740 pmp) were on dialysis and 16 765 (287 pmp) with renal graft. This census of the Italian RU and DC in 2004 provides decision makers and healthcare stakeholders with detailed data for benchmarking and has financial implications for the public health system. Similar analyses may be conducted in other countries permitting standardization of medical and cost-related aspects of renal care.

Oligoanuric forms of postdiarrheal hemolytic uremic syndrome (D+ HUS) usually have more severe acute stage and higher risk of chronic sequelae than nonoligoanuric forms. During the diarrheal phase, gastrointestinal losses could lead to dehydration with pre-renal injury enhancing the risk of oligoanuric D+ HUS. Furthermore, it had been shown that intravenous volume expansion during the prodromal phase could decrease the frequency of oligoanuric renal failure. Thus, we performed this retrospective study to determine whether dehydration on admission is associated with increased need for dialysis in D+ HUS patients. Data from 137 children was reviewed, which were divided into two groups according to their hydration status at admission: normohydrated (n = 86) and dehydrated (n = 51). Laboratory parameters of the dehydrated patients reflected expected deteriorations (higher urea, higher hematocrit and lower sodium, bicarbonate, and pH) than normohydrated ones. Likewise, the dehydrated group had a higher rate of vomiting and need for dialysis (70.6 versus 40.7 %, p = 0.0007). Our data suggests that dehydration at hospital admission might represent a concomitant factor aggravating the intrinsic renal disease in D+ HUS patients increasing the need for dialysis. Therefore, the early recognition of patients at risk of D+ HUS is encouraged to guarantee a well-hydrated status.

The dialysis patient is confronted with hundreds of litres of dialysis solution per week, which pass the natural protective barriers of the body and are brought into contact with the tissue directly in the case of peritoneal dialysis or indirectly in the case of renal dialysis (hemodialysis). The components can be tested for living specimens or dead pyrogenic (fever-inducing) contaminations. The former is usually detected by cultivation and the latter by the endotoxin-specific Limulus Amoebocyte Lysate Assay (LAL). However, the LAL assay does not reflect the response of the human immune system to the wide variety of possible pyrogenic contaminations in dialysis fluids. Furthermore, the test is limited in its sensitivity to detect extremely low concentrations of pyrogens, which in their sum result in chronic pathologies in dialysis patients. The In vitro Pyrogen Test (IPT) employs human whole blood to detect the spectrum of pyrogens to which humans respond by measuring the release of the endogenous fever mediator interleukin-1beta. Spike recovery checks exclude interference. The test has been validated in an international study for pyrogen detection in injectable solutions. In this study we adapted the IPT to the testing of dialysis solutions. Preincubation of 50 ml spiked samples with albumin-coated microspheres enhanced the sensitivity of the assay to detect contaminations down to 0.1 pg/ml LPS or 0.001 EU/ml in water or saline and allowed pyrogen detection in dialysis concentrates or final working solutions. This method offers high sensitivity detection of human-relevant pyrogens in dialysis solutions and components.

Full Text Available Background: Hepatitis C virus (HCV infection and chronic kidney disease are common and potentially serious medical problems throughout the world. In recent years, it has become clear that these two conditions are linked in several important ways. Indeed, some forms of renal diseases are precipitated by HCV infection and patients with end-stage renal disease (ESRD are at increased risk for acquiring HCV infection. Patients with chronic kidney disease typically show an impaired immune response compared with healthy individuals and also other risk factors related with treatment and management. CKD patients ultimately undergo end stage renal therapy like dialysis for their treatment and survival. Risk factors for the infections are more in dialysis period than in predialytic stages. Like other developing countries CKD patients with HCV infection are very common in our country. For this reason the CKD patients should be properly diagnosed knowing the infection status before dialysis which would help both the patient and doctor to choose their proper treatment approach. Objective: This cross-sectional study was done to know the prevalence of HCV infection in the CKD patients before starting dialysis therapy. Materials and Methods: A total of 197 patients with chronic kidney disease stage five (CKD-V before starting dialysis therapy were included as subjects of this study. Among the CKD patients anti-HCV was detected to see prevalence of hepatitis C virus infection. The patients were also tested for HBsAg to assess co-infection. After collecting all the data of different test results analyses were done by SPSS version 15.0. Results: In this study 195 (99% patients were anti-HCV negative and only two patients (1% were found positive. Conclusion: HCV infection in CKD patients before dialysis should be taken into account so that HCV negative CKD patients would not get the infection during dialysis and standard screening procedures should be taken to

Patients with end-stage renal disease (ESRD) require dialysis to maintain survival. The optimal timing of dialysis initiation in terms of cost-effectiveness has not been established. We developed a simulation model of individuals progressing towards ESRD and requiring dialysis. It can be used to analyze dialysis strategies and scenarios. It was embedded in an optimization frame worked to derive improved strategies. Actual (historical) and simulated survival curves and hospitalization rates were virtually indistinguishable. The model overestimated transplantation costs (10%) but it was related to confounding by Medicare coverage. To assess the model's robustness, we examined several dialysis strategies while input parameters were perturbed. Under all 38 scenarios, relative rankings remained unchanged. An improved policy for a hypothetical patient was derived using an optimization algorithm. The model produces reliable results and is robust. It enables the cost-effectiveness analysis of dialysis strategies.

Pharmacokinetic data of disease modifying antirheumatic drugs during hemodialysis are limited to sulfasalazine, methotrexate, and cyclosporine. Only respective anecdotal data have been reported on leflunomide. We repeatedly measured teriflunomide (A77-1726), the active metabolite of leflunomide, during standard hemodialysis sessions and calculated teriflunomide clearances in five patients with rheumatoid arthritis (RA) and end-stage renal disease. The calculated teriflunomide clearances during a standardized dialysis session of 3-4.5 h at a blood flow rate of 160-300 ml/min were between 0 and 4.3 ml/min, the mean clearances of the total dialysis ranged between 1.1 and 3.4 ml/min. Total amount of teriflunomide removed was 5.8-8.8 μg per dialysis session. Dialytic removal of the active metabolite of leflunomide, teriflunomide (A77-1726), is negligible. Leflunomide can be used for RA patients on chronic dialysis without any dosage modification.

Liver biopsy is performed for various indications in dialysis patients. Being a less-common subset, the hepatic pathology in renal dialysis is not well documented. Idiopathic noncirrhotic portal hypertension (INCPH) is a clinical entity associated with unexplained portal hypertension and/or a spectrum of histopathological vascular changes in the liver. After encountering INCPH and vascular changes of INCPH in 2 renal dialysis patients, we sought to further investigate this noteworthy association. A random search for patients on hemodialysis or peritoneal dialysis with liver biopsy was performed. Hematoxylin and eosin, reticulin, trichrome, and CK7 stains were performed on formalin-fixed, paraffin-embedded tissue sections. Histopathological features were reviewed, and the results were correlated with clinical findings. In all, 13 liver biopsies were retrieved. The mean cumulative duration of dialysis was 50 months (range = 17 months to 11 years). All patients had multiple comorbidities. Indications for biopsy were a combination of abnormal liver function tests (6), portal hypertension (4), ascites (3), and possible cirrhosis (3). Two patients with portal hypertension underwent multiple liver biopsies for diagnostic purposes. All (100%) biopsies showed some histological features of INCPH, including narrowed portal venous lumen (9), increased portal vascular channels (8), shunt vessels (3), dilated sinusoids (9), regenerative nodule (5), and features of venous outflow obstruction (3). No cirrhosis was identified. Liver biopsies from patients on dialysis demonstrate histopathological vascular changes of INCPH. Some (31%) patients present with portal hypertension without cirrhosis. The histological changes may be reflective of underlying risk factors for INCPH in this group. © The Author(s) 2015.

In Venezuela there are 3234 new cases (132 per million population [pmp]) requiring renal replacement therapy each year, and only 40% of these are admitted to the different modalities of dialysis. In the year 2000, there were 195 patients pmp in chronic hemodialysis (4700 patients). Diabetes, glomerular diseases, and hypertension account for more than 60% of the patients in chronic dialysis. Gross mortality in hemodialysis is around 20%, and cardiovascular causes are the primary cause of death (39.5%). Hospital admission in the dialysis patients amounts to 4.6 days/patient/year. Rehabilitation is inadequate. Only 45% of the dialysis patients report normal home or work activities. Transplantation in Venezuela has a general graft survival rate of 83% at 1 year (90% for living related grafts) and 50% (64% for living related grafts) at 10 years. Future tendencies include emphasis in preventive strategies, including early detection and treatment of diabetes and hypertension, as well as efforts to increase the rate of renal transplantation.

To determine the factors predicting renal outcome in patients developing acute renal failure in pregnancy. Study Design: Descriptive cohort study. Place and Duration of Study: Study was conducted at Nephrology Unit of Sindh Institute of Urology and Transplantation, Karachi, from October 2006 to March 2007. Methodology: Patients with acute renal failure due to complications of pregnancy, with normal size of both the kidneys on ultrasound were enrolled, and followed for a period of 60 days or until recovery of renal function. Patient's age and parity, presence of antenatal care, type of complication of pregnancy, foetal outcome and duration of oliguria were compared between patients who remained dialysis dependent and those who recovered renal function. Chi-square/Fisher's exact test and student's t-test, were used for determining the association of categorical and continuous variables with dialysis dependency. Results: The mean age was 29 +- 6 years. Most patients came from rural areas of interior Sindh. Sixty eight percent did not have antenatal checkups. Antepartum haemorrhage (p=0.002) and prolonged duration of oliguria (35 +- 15.7 days, p= < 0.001) were associated with dialysis dependency, which was observed in 50% of the study group. Conclusion: Ante-partum haemorrhage and prolonged oliguria were strong predictors of irreversible renal failure. This highlights the need for early recognition and referral, and the importance of trained birth attendants and antenatal care. (author)

OBJECTIVES: To determine the roles of body size and longitudinal body weight changes in the survival of incident peritoneal dialysis patients. PATIENTS AND METHODS: Patients (n = 1911) older than 18 years of age recruited from 114 dialysis centers (Dec/2004-Oct/2007) and participating in the Brazilian Peritoneal Dialysis Multicenter Cohort Study were included. Clinical and laboratory data were collected monthly (except if the patient received a transplant, recovered renal function, was transferred to hemodialysis, or died). RESULTS: Survival analyses were performed using Kaplan-Meier survival curves and Cox proportional hazards. Total follow-up was 34 months. The mean age was 59 years (54% female). The weight category percentages were as follows: underweight: 8%; normal: 51%; overweight: 29%; and obese 12%. The multivariate model showed a higher risk of death for a body mass index 30 kg/m2. Patients were divided into five categories according to quintiles of body weight changes during the first year of dialysis: +7.1%. Patients in the lowest quintile had significantly higher mortality, whereas no negative impact was observed in the other quintiles. CONCLUSION: These findings suggest that overweight/obesity and a positive body weight variation during the first year of peritoneal dialysis therapy do not increase mortality in incident dialysis patients in Brazil.

Metformin-associated lactic acidosis in a peritoneal dialysis patient

Directory of Open Access Journals (Sweden)

Najlaa Almaleki

2015-01-01

Full Text Available Metformin is one of the commonly used drugs in type-2 diabetes mellitus. It reduces glucose levels by increasing insulin sensitivity, reducing hepatic glucose release and increasing muscle uptake. One of the serious complications associated with metformin use is lactic acidosis, and it is associated with high morbidity and mortality. This is more likely to happen in patients with renal failure due to reduced clearance. International guidelines recommend discontinuing metformin in advanced renal failure. We report a case of metformin-associated lactic acidosis in a patient with end-stage renal disease on peritoneal dialysis. The patient presented with severe lactic acidosis, which was successfully treated with hemodialysis.

Background: In peritoneal dialysis (PD), residual renal function (RRF) fundamentally contributes to improved quality of life and patient survival. High glucose and advanced glycation end-products (AGE) contribute locally to peritoneal and systemically to renal damage. Integrity of podocyte structure and function is of special importance to preserve RRF. Benfotiamine could counteract the glucose and AGE-mediated toxicity by blocking hyperglycemia-associated podocyte damage via the pentose-phos...

Renal cancer occurs more frequently in renal transplanted patients than in the general population, affecting native kidneys in 90% of cases and the graft in 10 %. In addition to general risk factors, malignancy susceptibility may be influenced by immunosuppressive therapy, the use of calcineurin inhibitors (CNI) as compared with mammalian target of rapamycin inhibitors, and the length of dialysis treatment. Acquired cystic kidney disease may increase the risk for renal cancer after transplantation, while autosomal dominant polycystic kidney disease does not seem to predispose to cancer development. Annual ultrasound evaluation seems appropriate in patients with congenital or acquired cystic disease or even a single cyst in native kidneys, and every 2 years in patients older than 60 years if they were on dialysis for more than 5 years before transplantation. Immunosuppression should be lowered in patients who develop renal cancer, by reduction or withdrawal of CNI. Although more evidence is still needed, it seems reasonable to shift patients from CNI to everolimus or sirolimus if not already treated with one of these drugs, with due caution in subjects with chronic allograft nephropathy.

ESRD requiring dialysis is associated with increased morbidity and mortality rates, including increased rates of cognitive impairment, compared with the general population. About one quarter of patients receiving dialysis choose to discontinue dialysis at the end of life. Advance directives are intended to give providers and surrogates instruction on managing medical decision making, including end of life situations. The prevalence of advance directives is low among patients receiving dialysis. Little is known about the contents of advance directives among these patients with advance directives. We retrospectively reviewed the medical records of all patients receiving maintenance in-center hemodialysis at a tertiary academic medical center between January 1, 2007 and January 1, 2012. We collected demographic data, the prevalence of advance directives, and a content analysis of these advance directives. We specifically examined the advance directives for instructions on management of interventions at end of life, including dialysis. Among 808 patients (mean age of 68.6 years old; men =61.2%), 49% had advance directives, of which only 10.6% mentioned dialysis and only 3% specifically addressed dialysis management at end of life. Patients who had advance directives were more likely to be older (74.5 versus 65.4 years old; Phydration (34.3%), and pain management (43.4%) than dialysis (10.6%). Although one-half of the patients receiving dialysis in our study had advance directives, end of life management of dialysis was rarely addressed. Future research should focus on improving discernment and documentation of end of life values, goals, and preferences, such as dialysis-specific advance directives, among these patients.

The number of patients receiving chronic dialysis treatment in Japan currently exceeds 300,000 people. Few reports have described carotid endarterectomy(CEA)for chronic renal failure patients because of the unacceptable rate of perioperative stroke and other morbidities. A strategy for and treatment results of CEA for chronic renal failure patients in our hospital are described herein. The present study included 6 patients who underwent CEA while receiving dialysis treatment between April 2011 and November 2014. Dialysis treatment was initiated due to diabetes in 4 patients and renal sclerosis in 2 patients. All the patients were men, with a mean age of 74.0 years. Two patients were symptomatic, and four were asymptomatic. In all the patients, heart vascular lesions and arteriosclerosis risk factors were present. Postoperatively, pneumonia transient cranial neuropathy, heart failure, and pneumonia in 1 case required extensive treatment. However, by the time of discharge from hospital, no cases had deteriorated compared with their pre-CEA state. The modified Rankin scale score on discharge was 0-2 for all the patients. CEA can be performed safely in patients receiving dialysis, but further operative procedures and careful postoperative management are likely to be needed for patients with CEA who are receiving dialysis.

Diabetic nephropathy. Is end-stage renal disease inevitable?

Science.gov (United States)

Bogusky, R T

1983-10-01

The appearance of proteinuria in an insulin-dependent diabetic patient is an ominous sign. Proteinuria heralds the presence of diabetic nephropathy and early death, or chronic renal failure requiring dialysis or transplantation, in 50% of patients. The pathogenesis of diabetic nephropathy is unknown. Adequate insulin administration is the most important preventive measure. Hypertension, if present, should be aggressively treated to delay progression of renal disease. Good nutrition, prompt treatment of urinary tract infections, and caution in the use of radiocontrast agents are other important preventive measures. Hemodialysis, peritoneal dialysis, and transplantation are options for patients with end-stage renal disease. No matter which is selected, the patient may still have multiple amputations, blindness, congestive heart failure, infections, and uncontrolled glycemia. Advancements are being made, however, that promise a better future for insulin-dependent diabetics.

This study aims to investigate the application value of Internet-based instant messaging software in the follow-up of patients using peritoneal dialysis. Peritoneal dialysis is an effective renal replacement treatment for end-stage renal disease. The clinical usefulness of Internet-based instant messaging software in the follow-up of peritoneal dialysis patients, including the incidence of peritonitis and exit-site infection, the levels of albumin and electrolytes and the degree of patients' satisfaction, remains unknown. Between January 2009-April 2016, a total of 160 patients underwent continuous peritoneal dialysis in the Department of Nephrology, Fujian Provincial Hospital were invited to participate voluntarily in this study. The patients were randomly assigned to the instant messenger (QQ) follow-up group (n = 80) and the traditional follow-up group (n = 80). The differences in death, hospitalisation, peritonitis, exit-site infection, and patients' satisfaction were investigated during 1 year of follow-up. The mean follow-up duration is 11.4 ± 1.5 months. Compared with the patients in the traditional follow-up group, patients in the QQ follow-up group showed higher levels of serum albumin (p = .009) and haemoglobin (p = .009), lower levels of phosphorus (p instant messaging software appears to be a feasible and acceptable method of delivering peritoneal dialysis treatment for patients with end-stage renal disease. © 2018 John Wiley & Sons Ltd.

Directory of Open Access Journals (Sweden)

Reika Imai

2017-12-01

Full Text Available Peritoneal dialysis (PD is an accepted modality for managing end-stage kidney disease. We herein report a 75-year-old female patient on chronic PD who was complicated by renal cell carcinoma. She was successfully treated with retroperitoneal laparoscopic radical nephrectomy followed by a prompt resumption of the procedure. Various surgeries disturbing the abdominal wall integrity often disrupt the regular PD schedule, and using minimally invasive approaches is therefore an attractive therapeutic option. Our experience emphasizes the feasibility and safety of a retroperitoneal approach–based laparoscopic technique based on several empirical examples. However, systemic studies on this topic are obviously lacking, so we strongly recommend the accumulation of more cases similar to our own. Several surgical concerns that need to be dealt with among PD patients are also discussed.

A number of considerations suggest that trace element disturbances might occur in patients with renal disease and in hemodialysis (HD) patients. Using particle induced X-ray emission, we demonstrated the relations between serum concentration, urinary excretion of the trace elements and creatinine clearance (Ccr) in randomized 50 patients. To estimate the effects of HD, we also observed the changes of these elements in serum and dialysis fluids during HD. Urinary silicon excretion decreased, and serum silicon concentration increased as Ccr decreased, with significant correlation (r=0.702, p<0.001 and r=0.676, p<0.0001, respectively). We also observed the increase of serum silicon, and the decrease of silicon in dialysis fluids during HD. These results suggested that reduced renal function and also dialysis contributed to silicon accumulation. Although serum selenium decreased significantly according to Ccr decrease (r=0.452, p<0.01), we could detect no change in urinary selenium excretion and no transfer during HD. Serum bromine and urinary excretion of bromine did not correlate to Ccr. However we observed a bromine transfer from the serum to the dialysis fluid that contributed to the serum bromine decrease in HD patients

To characterize and evaluate complications and outcomes of the patients treated with automated peritoneal dialysis (PD) at the University Hospital of the West Indies (UHWI), Jamaica. Retrospective data were collected from peritoneal dialysis patients' case files retrieved from the medical records department of UHWI. Demographic data (age, gender address, marital status), year of dialysis commencement, cause of end stage renal disease (ESRD), haemoglobin, serum electrolytes, serology, blood pressure readings, medications used, blood transfusion and erythropoietin use were collated. Complications such as infections (pneumonia, catheter-related infections), cardiac related disorders (congestive cardiac failure, acute coronary syndrome, pericarditis/pericardial effusion), cerebrovascular diseases, renal osteodystrophy, complications of the procedure and of end stage renal disease (ESRD), outcome and cause of death were retrieved from patients' case files for analysis. There were 202 patients receiving peritoneal dialysis between September, 1999 and December 2008. Data on 190 were analysed. The case files of 12 patients were not included because of incomplete data. The ages of the studied PD patients ranged between 33 and 65 years. The mean haemoglobin was 7.4 g/dL, serum calcium of 2.1 mmol/L, serum phosphate of 1.9 mmol/L and calcium/phosphate product of 4.1mmol2/L2. The serum albumin was 32 g/L and serum total cholesterol/HDL ratio of 5.3. Most patients were from Kingston and St Andrew (56.8%), St Catherine (18.9%) and Clarendon (7.4%). Hypertension (27.9%), chronic glomerulonephritis (17.9%) and diabetes mellitus (17.4%) were the commonest causes of ESRD. There were 70.5% unmarried persons and 81.6% of patients were unemployed. HIV, Hepatitis B and Hepatitis C seropositivity were discovered in 4.1%, 1.1 and 0.5% of patients respectively. Only 20% of the patients used erythropoietin and of this 92% used it less than 50% of the prescribed frequency. Infections (43

Physicians frequently search bibliographic databases, such as MEDLINE via PubMed, for best evidence for patient care. The objective of this study was to develop and test search filters to help physicians efficiently retrieve literature related to dialysis (hemodialysis or peritoneal dialysis) from all other articles indexed in PubMed, Ovid MEDLINE, and Embase. A diagnostic test assessment framework was used to develop and test robust dialysis filters. The reference standard was a manual review of the full texts of 22,992 articles from 39 journals to determine whether each article contained dialysis information. Next, 1,623,728 unique search filters were developed, and their ability to retrieve relevant articles was evaluated. The high-performance dialysis filters consisted of up to 65 search terms in combination. These terms included the words "dialy" (truncated), "uremic," "catheters," and "renal transplant wait list." These filters reached peak sensitivities of 98.6% and specificities of 98.5%. The filters' performance remained robust in an independent validation subset of articles. These empirically derived and validated high-performance search filters should enable physicians to effectively retrieve dialysis information from PubMed, Ovid MEDLINE, and Embase.

Lockridge, Robert S; Pipkin, Mary

When hemodialysis first started in the United States in the 1960s, a large percentage of patients performed their treatments at home. However, because of reimbursement issues, home hemodialysis (HHD) gradually succumbed to an in-center approach and eventually a mindset. Since the introduction of nightly HHD by Uldall and Pierratos in 1993, there has been a resurgence of interest in HHD. This paper describes the different types of home hemodialysis being performed as of December 31, 2007 in this country. Because neither the United States Renal Data System (USRDS) nor the End Stage Renal Disease (ESRD) Networks break down home dialysis into the different modalities, a provider questionnaire was sent out to 2 major providers, a number of mid-level providers and other providers known to do HHD. In addition, a questionnaire was sent out to 3 machine providers to obtain the number of patients using their machine for HHD as of December 31, 2007. The results showed that 91.7% of patients are dialyzing in-center, 7.3% are doing peritoneal dialysis, and 0.7% are doing HHD. Currently about 1% of ESRD patients in the United States are doing home hemodialysis. NxStage, however, has started 1000 patients in the past year on short-daily home hemodialysis. Patients are beginning to understand that there are better options than 3 times a week in-center dialysis. And as a result of the "HEMO Study," nephrologists now believe that longer and more frequent dialysis is a better therapy for ESRD patients. Therefore, promotion of HHD should become a priority for the renal community in the future.

The incidence of pregnancy in patients with chronic kidney disease (CKD) undergoing hemodialysis is rare. Forpregnant patients with CKD undergoing regular hemodialysis, the effects of renal disease on the fetus should be noted and require specific strategies. A 30-year-old woman had no menstruation for 4 months. Abdominal ultrasound showed single fetus within 16 weeks of pregnancy. She had previously been in regular hemodialysis twice a week since 2015, then the frequency of hemodialysis was increased to thrice a week for 4 hours/dialysis. During pregnancy, she was given erythropoiesis stimulating agent, controlled protein nutrition (0.6-1.5g/kg/day) and routine pregnancy controls to an obstetrician. After 31-32 weeks gestation, thebaby was born alive with low birth weight (1800g). Maintaining pregnancy in women with regular hemodialysis is still challenging and difficult. Prolonged/intensive dialysis during pregnancy results in longer gestational periods, higher fetal weights, and a higher likelihood of survival. Based on a dialysis guideline for pregnancy in CKD, hemodialysis is performed at least 20 hours/week to maintain pre-dialysis of BUN≤50mg/dl hemoglobin should be at least 10-11g/dL. We reported a case of pregnancy in dialysis CKD patient undergoing hemodialysis thricea week (4 hours/dialysis). The baby was born alive with low birth weight (1800 g).

Aliskiren prevents the toxic effects of peritoneal dialysis fluids during chronic dialysis in rats.

Directory of Open Access Journals (Sweden)

Juan Pérez-Martínez

Full Text Available The benefits of long-term peritoneal dialysis (PD in patients with end-stage renal failure are short-lived due to structural and functional changes in the peritoneal membrane. In this report, we provide evidence for the in vitro and in vivo participation of the renin-angiotensin-aldosterone system (RAAS in the signaling pathway leading to peritoneal fibrosis during PD. Exposure to high-glucose PD fluids (PDFs increases damage and fibrosis markers in both isolated rat peritoneal mesothelial cells and in the peritoneum of rats after chronic dialysis. In both cases, the addition of the RAAS inhibitor aliskiren markedly improved damage and fibrosis markers, and prevented functional modifications in the peritoneal transport, as measured by the peritoneal equilibrium test. These data suggest that inhibition of the RAAS may be a novel way to improve the efficacy of PD by preventing inflammation and fibrosis following peritoneal exposure to high-glucose PDFs.

The Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (SCOPE) Collaborative is a quality improvement initiative to reduce dialysis-associated infections. The frequency of peritoneal dialysis (PD) catheter exit site infection (ESI) and variables influencing its development and end result are unclear. We sought to determine ESI rates, to elucidate the epidemiology, risk factors, and outcomes for ESI, and to assess for association between provider compliance with care bundles and ESI risk. We reviewed demographic, dialysis and ESI data, and care bundle adherence and outcomes for SCOPE enrollees from October 2011 to September 2014. ESI involved only the exit site, only the subcutaneous catheter tunnel, or both. A total of 857 catheter insertions occurred in 734 children over 10,110 cumulative months of PD provided to these children. During this period 207 ESIs arose in 124 children or 0.25 ESIs per dialysis year. Median time to ESI was 392 days, with 69% of ESIs involving exit site only, 23% involving the tunnel only, and 8% involving both sites. Peritonitis developed in 6%. ESI incidence was associated with age (p = 0.003), being the lowest in children aged  0 at prior month's visit (p treatment, 24% required hospitalization, and 9% required catheter removal, generally secondary to tunnel infection. Exit site infections occur at an annualized rate of 0.25, typically well into the dialysis course. Younger patient age and documented review of site care are associated with lower ESI rates. Although most ESIs resolve, hospitalization is frequent, and tunnel involvement/catheter loss complicate outcomes.

Full Text Available Introduction: A chronic disease changes the patients functioning in many different areas of their lives. Most of them cannot accept the disease and rarely make an effort to change their current health situation. Aim of the study: To define the level of acceptance of the disease as well as the preferred ways of coping with stress in patients on dial‑ ysis, suffering from chronic renal disease. Material and methods: Ninety-four patients on dialysis, with chronic renal failure, were examined. The study was conducted in two dialysis units: Dialyses Centre Fresenius Nephrocare III in Bydgoszcz and NZOZ Avitum, Dialysis Unit in Nakło. Adjustment to the disease was assessed using the Accep‑ tance of Illness Scale (AIS adapted by Juczyński, the way of dealing with stressful situations was tested using CISS questionnaire by Endler and Parker, in Polish adaptation by Szczepanik, Strelau and Wrześniewski. Results: The examined group reached the average level of the disease acceptance. Men, people aged up to 59 years and those living in towns exhibit a higher level of disease acceptance. The higher the education level, the higher the patient’s ability to adjust to the disease. The most common style of coping with stress was the task-oriented style which was followed by the emotion-oriented style and the avoidance-oriented style. The  level of  the disease acceptance decreased with increasing emotion-oriented style. Conclusions: The obtained results will help to understand people with chronic renal failure, assist them in finding new ways of coping with stress, and thereby increase the acceptance of the disease. They will also allow to plan a better care for dialysis patients.

Current transplant success allows recipients with previous contraindications to transplant to have access to this procedure with more frequency and safety. The concept of high-risk patient has changed since the first stages of transplantation. In the first studies, the high-risk concept was based on probability of early graft failure or on a patient's clinical condition to cope with high perioperatory morbimortality. Later on, this concept implied immunological factors that were crucial to ensure transplant success because hypersensitized or polytransfused patients experienced a higher risk of acute rejection and subsequent graft loss. Afterward, the presence of various comorbidities would redefine the high-risk concept for renal transplant mainly considering recipient's clinical aspects. Currently, the change in epidemiological characteristics of patients starting dialysis causes that we now deal with a greater increase of elderly patients, diabetic patients, and patients with history of cardiovascular disease. Today, high-risk patients are those with clinical features that predict an increase in the risk of perioperative morbimortality or death with functioning graft. In this review, we will attempted to analyze currents results of renal transplant outcomes in terms of patients and graft survival in elderly patients, diabetic patients, and patients with previous cardiovascular disease from the most recent experiences in the literature and from experiences in our center. In any of the groups previously analyzed, survival offered by renal transplant is significantly higher compared to dialysis. Besides, these patients are the recipient group that benefit the most with the transplant because their mortality while remaining on dialysis is extremely high. Hence, renal transplantation should be offered more frequently to older patients, diabetic patients, and patients with pretransplant cardiac and peripheral vascular disease.

Little information is available regarding the influence of dialysis facility size or profit status on intermediate outcomes in chronic dialysis patients. We have combined data from the Health Care Financing Administration (HCFA) Core Indicators Project; the end-stage renal disease (ESRD) facility survey; and the HCFA On-Line Survey, Certification, and Reporting System to analyze trends in this area. For hemodialysis patients, larger facilities were more likely than smaller facilities to perform dialysis on patients who were younger than 65 years of age, black, or undergoing dialysis 2 years or more (P profit units (P reduction ratio, but not with hematocrit or serum albumin values. Facility profit status was not associated with these intermediate outcomes. For peritoneal dialysis patients, there were no significant differences in patient demographics based on facility size. More patients in nonprofit units had been undergoing dialysis 2 or more years than patients in for-profit units (P profit status.

Due to poverty, many countries of sub-Saharan Africa suffer a severe burden of end-stage renal disease (ESRD), the cause of which is often unidentified. We sought to identify biopsy-proven causes of ESRD in Cape Town, South Africa, and to determine the outcome of these patients. Records of biopsies reported as ESRD over a 10-year period were selected for analysis. The demographic, clinical and biochemical characteristics of the patients at the time of biopsy were documented. The decision of the committee that assesses the eligibility of patients for long-term renal replacement therapy (RRT) was documented, and if a patient was not accepted the reasons for the rejection were noted. Chronic glomerulonephritis (CGN) was the most frequent cause of ESRD (31.2%); human immunodeficiency virus-associated nephropathy (HIVAN) accounted for 12.5% of ESRD cases. Sixty-six patients (45.8%) were never reviewed by the assessment committee for placement in the dialysis program. Of the remaining 78 patients (54.2%) reviewed for RRT, only 48/78 (61.5%) were selected. A higher frequency of patients with HIVAN were not accepted for RRT (17.7%) than patients with HIVAN who were accepted (2.1%) (p=0.008). Social factors such as lack of housing, alcohol abuse, illicit drug abuse, lack of transportation and lack of family/social support accounted for 56.7% of patients not being accepted for RRT. There needs to be a development of programs amongst Africans to provide effective solutions that tackle the burden of ESRD, especially related to the increasing prevalence of HIVAN.

The aim of the present study was to investigate psychosocial variables related to objective and subjective indicators of quality of life in a single center cohort study of patients undergoing in-center hemodialysis (Hd), Continuous Ambulatory Peritoneal Dialysis (CAPD) and renal transplant recipients (RTx). We studied 40 HD patients, 36 CAPD, and 48 RTx patients by a special questionnaire examining demographics, functional status, employment status, and impact of therapy on psychosocial issues such as anxiety and depression. The RTx patients disclosed a better functional and employment status than the CAPD and the HD patients. They were also more compliant and satisfied with their therapy and their relationship with the medical and nursing personnel. The CAPD patients were also more satisfied, more compliant, better motivated, and less anxious and depressed compared with the HD patients who scored low in every aspect studied. Successful renal transplantation is a superior modality of therapy than HD or CAPD regarding psychosocial and quality of life issues. However these results can partially be explained by some selection bias, as RTx patients are usually younger and CAPD patients are selected for this modality after examining functional and social status.

USE OF SILDENAFIL (VIAGRA® FOR ERECTILE DYSFUNCTION IN DIALYSIS PATIENTS – OUR FIRST EXPERIENCE

Directory of Open Access Journals (Sweden)

Bojan Vujkovac

2002-01-01

Full Text Available Background. Male patients with end stage renal disease often report erectile dysfunction, which is very common especially in younger males. Impotence is reported to exceed 50% in male chronic renal failure patients, and is present in 65% of such patients undergoing hemodialysis. Numerous etiological factors have been reported as possible cause for sexual dysfunction. Sildenafil (Viagra®, a potent specific inhibitor of cGMP phosphodiesterase, was used in this case study to improve erectile dysfunction in dialysis male patients.Methods and results. During 12 weeks we treated 4 dialysis patients. 2 patients were treated with peritoneal dialysis and 2 patients were in the program of chronic hemodialysis. All patients were in the program of dialysis for more than 24 months, and reported erectile dysfunction and impotence after they had started with dialysis treatment. Sildenafil was used in the treatment. The dosage schedule for sildenafil was 50mg/ week orally for 2 weeks followed by 100 mg/week for the next 10 weeks if there was no effect on initial dosage. Efficacy of treatment was evaluated by means of the International Index of Erectile Dysfunction. All 4 patients reported no significant effect on initial dose. With higher dose of sildenafil treatment was overwhelmingly successful, with reported prolonged improvement of erectile dysfunction for 42 to 72 hours. Side effects were present only in 1 patient who had severe headaches after higher dose. No patients experienced priapism.Conclusions. There have been only few reports in the literature on the use of sildenafil in dialysis patients. Our small case study suggests that sildenafil could be successfully and safely used for treatment of erectile dysfunction also in dialysis patients. A large trial would be necessary to confirm the efficacy of the drug for this specific group of patients.

Use of the 'Accountability for Reasonableness' Approach to Improve Fairness in Accessing Dialysis in a Middle-Income Country.

Directory of Open Access Journals (Sweden)

Mohammed Rafique Moosa

Full Text Available Universal access to renal replacement therapy is beyond the economic capability of most low and middle-income countries due to large patient numbers and the high recurrent cost of treating end stage kidney disease. In countries where limited access is available, no systems exist that allow for optimal use of the scarce dialysis facilities. We previously reported that using national guidelines to select patients for renal replacement therapy resulted in biased allocation. We reengineered selection guidelines using the 'Accountability for Reasonableness' (procedural fairness framework in collaboration with relevant stakeholders, applying these in a novel way to categorize and prioritize patients in a unique hierarchical fashion. The guidelines were primarily premised on patients being transplantable. We examined whether the revised guidelines enhanced fairness of dialysis resource allocation. This is a descriptive study of 1101 end stage kidney failure patients presenting to a tertiary renal unit in a middle-income country, evaluated for dialysis treatment over a seven-year period. The Assessment Committee used the accountability for reasonableness-based guidelines to allocate patients to one of three assessment groups. Category 1 patients were guaranteed renal replacement therapy, Category 3 patients were palliated, and Category 2 were offered treatment if resources allowed. Only 25.2% of all end stage kidney disease patients assessed were accepted for renal replacement treatment. The majority of patients (48% were allocated to Category 2. Of 134 Category 1 patients, 98% were accepted for treatment while 438 (99.5% Category 3 patients were excluded. Compared with those palliated, patients accepted for dialysis treatment were almost 10 years younger, employed, married with children and not diabetic. Compared with our previous selection process our current method of priority setting based on procedural fairness arguably resulted in more equitable

Quality Measures for Dialysis: Time for a Balanced Scorecard.

Kliger, Alan S

2016-02-05

Recent federal legislation establishes a merit-based incentive payment system for physicians, with a scorecard for each professional. The Centers for Medicare and Medicaid Services evaluate quality of care with clinical performance measures and have used these metrics for public reporting and payment to dialysis facilities. Similar metrics may be used for the future merit-based incentive payment system. In nephrology, most clinical performance measures measure processes and intermediate outcomes of care. These metrics were developed from population studies of best practice and do not identify opportunities for individualizing care on the basis of patient characteristics and individual goals of treatment. The In-Center Hemodialysis (ICH) Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey examines patients' perception of care and has entered the arena to evaluate quality of care. A balanced scorecard of quality performance should include three elements: population-based best clinical practice, patient perceptions, and individually crafted patient goals of care.

The case is reported of a 47-year-old man with a history of chronic renal failure, treated with peritoneal dialysis, who presented with acute sacroiliac joint pain secondary to a pelvic abscess. Initially a diagnosis of infectious sacroiliitis of the left sacroiliac joint was suspected, but following investigation a pain referable to the sacroiliac joint was suspected. The patient recovered with a combination of antibiotics for the pelvic abscess and non-steroidal anti-inflammatory drugs. PMID:21994518

Peritoneal dialysis: a primary care perspective.

As the population of chronic kidney disease (CKD) and end-stage renal disease (ESRD) grows at an alarming rate, primary care physicians will increasingly be involved in the management of these patients. Early recognition of CKD and timely referral to a nephrologist when glomerular filtration rate approaches 30 mL/min/1.73 m(2) is extremely important to improve ESRD outcome and appropriate selection of dialysis modality. Peritoneal dialysis (PD) remains a viable treatment option for ESRD patients. PD is less expensive dialysis modality and may provide a survival advantages over hemodialysis in first 2 to 4 years of treatment. Preserving residual renal function (RRF) is of paramount importance to prolong the survival outcomes in PD patients. Thus preservation of RRF is an important goal in the management of PD patients. Every effort should be made to avoid nephrotoxic drugs like aminoglycosides and nonsteroidal anti-inflammatory drugs, and limit the use of radiocontrast agents in PD patients with RRF. Judicious use of prophylactic antibiotics to prevent peritonitis would further help to reduce morbidity from PD. Protecting peritoneal membrane from long-term toxic and metabolic effects of the conventional glucose-based solutions is another objective to further improve PD outcome. Development of new, more biocompatible PD solutions holds promise for the future. One such solution, icodextrin, is now approved for use in the United States. Although extremely safe to use, it is associated with unique metabolic effects that may concern primary care physicians. They include false elevation of blood glucose, a reversible increase in serum alkaline phosphatase and a false decline in serum amylase. Monitoring of glycemia by assays that use glucose dehydrogenase pyrroloquinoline quinone enzymes should be avoided and serum amylase alone should not be relied on in diagnosing pancreatitis in patients on icodextrin.

In rodents with reduced renal mass, renal scarring has been attributed to poorly filtered, small protein-bound molecules. The best studied of these is indoxyl sulfate (IS.We have attempted to establish whether there are uremic toxins that are not effectively removed by hemodialysis. We examined plasma from patients undergoing hemodialysis, employing global gene expression in normal human renal cortical cells incubated in pre- and post- dialysis plasma as a reporter system. Responses in cells incubated with pre- and post-dialysis uremic plasma (n = 10 were compared with responses elicited by plasma from control subjects (n = 5. The effects of adding IS to control plasma and of adding probenecid to uremic plasma were examined. Plasma concentrations of IS were measured by HPLC (high pressure liquid chromatography.Gene expression in our reporter system revealed dysregulation of 1912 genes in cells incubated with pre-dialysis uremic plasma. In cells incubated in post-dialysis plasma, the expression of 537 of those genes returned to baseline but the majority of them (1375 remained dysregulated. IS concentration was markedly elevated in pre- and post-dialysis plasma. Addition of IS to control plasma simulated more than 80% of the effects of uremic plasma on gene expression; the addition of probenecid, an organic anion transport (OAT inhibitor, to uremic plasma reversed the changes in gene expression.These findings provide evidence that hemodialysis fails to effectively clear one or more solutes that effect gene expression, in our reporter system, from the plasma of patients with uremia. The finding that gene dysregulation was simulated by the addition of IS to control plasma and inhibited by addition of an OAT inhibitor to uremic plasma identifies IS

The IDEAL trial shows that the decision to start renal replacement treatment should not depend on GFR alone, but should be taken on the basis of clinical parameters. Quality of Life (QoL) questionnaires and bio-impedance analysis are potential tools for detecting subtle changes in the predialysis clinic. Too early an initiation of dialysis may be deleterious for the patient and the healthcare system. We are convinced that ESRD patients should be informed about intensive haemodialysis (HD), especially nocturnal (home) HD, as the best available dialysis modality. There is substantial evidence which shows that intensive HD improves clinical, biochemical and biological parameters, and may even prolong survival. We believe that 'just-in-time delivery of intensive haemodialysis' may result in optimised QoL and reduced economic burden.

The worldwide incidence of kidney failure is on the rise and treatment is costly; thus, the global burden of illness is growing. Kidney failure patients require either a kidney transplant or dialysis to maintain life. This review focuses on the economics of dialysis. Alternative dialysis modalities are haemodialysis (HD) and peritoneal dialysis (PD). Important economic factors influencing dialysis modality selection include financing, reimbursement and resource availability. In general, where there is little or no facility or physician reimbursement or payment for PD, the share of PD is very low. Regarding resource availability, when centre HD capacity is high, there is an incentive to use that capacity rather than place patients on home dialysis. In certain countries, there is interest in revising the reimbursement structure to favour home-based therapies, including PD and home HD. Modality selection is influenced by employment status, with an association between being employed and PD as the modality choice. Cost drivers differ for PD and HD. PD is driven mainly by variable costs such as solutions and tubing, while HD is driven mainly by fixed costs of facility space and staff. Many cost comparisons of dialysis modalities have been conducted. A key factor to consider in reviewing cost comparisons is the perspective of the analysis because different costs are relevant for different perspectives. In developed countries, HD is generally more expensive than PD to the payer. Additional research is needed in the developing world before conclusive statements may be made regarding the relative costs of HD and PD. PMID:18234844

The aim of the study is to improve the understanding of outcomes and complications of dialysis in adolescents and young adults (AYA) to inform decisions about dialysis modality in this patient population. Registry data on Australian AYA aged 13 to 20 years who commenced dialysis between 1/1/2000 and 31/12/2013 were retrieved from the Australia and New Zealand Dialysis and Transplantation Registry and analyzed to determine associations between demographic characteristics, dialysis modality and outcomes. During the study period 300 AYA commenced dialysis at a median age of 17.2 years (IQR 15.6 to 18.6 years). Haemodialysis (HD) was the initial dialysis modality in 201 patients (67%). No significant differences between AYA receiving HD and peritoneal dialysis (PD) were noted in patient gender, age, race, primary renal disease, treating centre type, remoteness of residential area, lateness of referral or period of study. Mean haemoglobin levels were lower in the HD group (P = 0.005) and significantly fewer HD patients attended school full time compared to patients managed on PD (P = 0.002 first year; P = 0.05 second year). Dialysis modality choice does not appear to be influenced by patient characteristics nor dialysis outcomes. Future research is required to examine the reasons that HD is preferred over PD and to determine the optimal method of dialysis for this age group. © 2016 Asian Pacific Society of Nephrology.

Residual renal function and the integrity of the peritoneal membrane contribute to morbidity and mortality among patients treated with peritoneal dialysis. Glucose and its degradation products likely contribute to the deterioration of the remnant kidney and damage to the peritoneum. Benfotiamine decreases glucose-induced tissue damage, suggesting the potential for benefit in peritoneal dialysis. Here, in a model of peritoneal dialysis in uremic rats, treatment with benfotiamine decreased peritoneal fibrosis, markers of inflammation, and neovascularization, resulting in improved characteristics of peritoneal transport. Furthermore, rats treated with benfotiamine exhibited lower expression of advanced glycation endproducts and their receptor in the peritoneum and the kidney, reduced glomerular and tubulointerstitial damage, and less albuminuria. Increased activity of transketolase in tissue and blood contributed to the protective effects of benfotiamine. In primary human peritoneal mesothelial cells, the addition of benfotiamine led to enhanced transketolase activity and decreased expression of advanced glycation endproducts and their receptor. Taken together, these data suggest that benfotiamine protects the peritoneal membrane and remnant kidney in a rat model of peritoneal dialysis and uremia.

In vitro thyroid function tests were performed in three groups of patients with chronic renal failure who were receiving, on average, 15, 18 and 27 hours of maintenance hemodialysis per week. Total thyroxine levels were low and total triiodothyronine levels low to normal in those receiving the least dialysis (15 hours), and were significantly higher in those receiving longer dialysis. Free thyroxine levels, as measured by the effective thyroxine ratio, were normal and similar in all three groups, as were serum thyrotrophin levels. All patients were clinically euthyroid. As total hormone levels showed a significant inverse relationship to both urea and creatinine, this study suggests that there is a dialyzable metabolite retained in uremia which competes with thyroid hormones for protein-binding sites.

Intoxication by star fruit (Averrhoa carambola) in six dialysis patients? (Preliminary report)

Science.gov (United States)

Neto, M M; Robl, F; Netto, J C

1998-03-01

We observed six cases of patients in a dialysis programme who were apparently intoxicated by ingestion of star fruit. After ingestion of 2-3 fruits or 150-200 ml of the fruit juice, the six patients, who had previously been stable in a regular dialysis programme, developed a variety of symptoms ranging from insomnia and hiccups to agitation, mental confusion and (in one case) death. In preliminary investigations to characterize the hypothetical neurotoxin in the fruit, an extract, when injected intraperitoneally or intracerebroventricularly in rats, provoked persistent convulsions of the tonic-clonic type. It appears that star fruit (Averrhoa carambola) contains an excitatory neurotoxin. Patients with renal failure on conservative or dialysis treatment should be dissuaded from ingestion of the fruit.

Published data on the comparative achievement of The Kidney Disease Dialysis Outcome Quality Initiative (KDOQI) recommended clinical performance targets between children and young adults on dialysis are scarce. To characterize the achievement of KDOQI targets among children (young adults (18-24 years) with prevalent end stage renal disease (ESRD), we performed a cross-sectional analysis of data collected by the Mid-Atlantic Renal Coalition, in conjunction with the 2007 and 2008 ESRD Clinical Performance Measures Projects. Data on all enrolled pediatric dialysis patients, categorized into three age groups (0-8, 9-12, 13-17 years), and on a random sample of 5% of patients ≥ 18 years in ESRD Network 5 were examined for two study periods: hemodialysis (HD) data were collected from October to December 2006 and from October to December 2007 and peritoneal dialysis (PD) data were collected from October 2006 to March 2007 and from October 2007 to March 2008. In total, 114 unique patients were enrolled the study, of whom 41.2% (47/114) were on HD and 58.8% (67/114) on PD. Compared to the pediatric patients, young adults were less likely to achieve the KDOQI recommended serum phosphorus levels and serum calcium × phosphorus product values, with less than one-quarter demonstrating values at or below each goal. Multivariate analysis revealed that both young adults and 13- to 17-year-olds were less likely to achieve target values for phosphorus [young adults: odds ratio (OR) 0.04, 95% confidence interval (95% CI) 0.01-0.19, p young adults: OR 0.01, 95% CI 0.002-0.09, p young adult ESRD patients.

In 2008, 563,294,000 people were living in Latin America (LA), of which 6.6% were older than 65. The region is going through a fast demographic and epidemiologic transition process, in the context of an improvement in socio-economic indices. The Latin American Dialysis and Renal Transplant Registry has collected data since 1991, through an annual survey completed by 20 affiliated National Societies. Renal replacement treatment (RRT) prevalence and incidence showed an increase year by year. The prevalence rate (in all modalities) correlated with the World Bank country classification by income and the epidemiologic transition stage the countries were experiencing. RRT prevalence and kidney transplantation rates correlated significantly with gross national income (GNI), health expenditure in constant dollars (HeExp), % older than 65, life expectancy at birth, and % of the population living in urban settings. Kidney transplantation increased also, year by year, with more than 50% of transplants performed using kidneys from deceased donors. Double transplants were performed in six countries. RRT prevalence and incidence increased in LA, and are associated with indexes reflecting higher and more evenly distributed national wealth (GNI and HeExp), and the stage of demographic and epidemiological transition.

Chronic renal insufficiency, hemodialysis, peritoneal dialysis, renal transplantation and administration of different medications provoke complex biochemical disturbances of the calcium-phosphate metabolism with wide spectrum of bone and soft tissue abnormalities termed renal osteodystrophy. Clinically most important manifestation of renal bone disease includes secondary hyperparathyroidism, osteomalacia/rickets, osteoporosis, adynamic bone disease and soft tissue calcification. As a complication of long-term hemodialysis and renal transplantation amyloid deposition, destructive spondyloarthropathy, osteonecrosis, and musculoskeletal infections may occur. Due to more sophisticated diagnostic methods and more efficient treatment classical radiographic features of secondary hyperparathyroidism and osteomalacia/rickets are now less frequently seen. Radiological investigations play an important role in early diagnosis and follow-up of the renal bone disease. Although numerous new imaging modalities have been introduced in clinical practice (scintigraphy, CT, MRI, quantitative imaging), plain film radiography, especially fine quality hand radiograph, still represents most widely used examination.

A 12-year-old Congolese girl presented with acute renal failure, edema, hypertension, hemoptysis, hematuria, and proteinuria after a history of throat infection. Renal ultrasound showed kidneys of normal size, with increased echogenicity of the cortical parenchyma and decreased corticomedullary differentiation. Other additional investigations showed pancytopenia with decreased complement (low C3 and C4). Antinuclear antibodies were strongly positive, including anti-double stranded DNA. Renal biopsy confirmed severe grade IV lupus nephritis. She was treated with high-dose steroids, mycophenolate mofetil and hydroxychloroquine, in addition to hemodialysis. After one week of intensive treatment, diuresis recovered and dialysis could be stopped after six sessions. We describe an uncommon case of severe lupus nephritis, presenting with terminal renal failure. Since the rarity of this disease presentation, other more common diagnoses have to be considered. Once the diagnosis of lupus nephritis is established, a choice has to be made between the different induction treatment protocols. The patient's ethnic background and other supportive therapies, such as the need for dialysis, can help to make this choice.

Hemodialysis patients have historically experienced diminished access to care and increased adverse outcomes after natural disasters. Although "early dialysis" in advance of a storm is promoted as a best practice, evidence for its effectiveness as a protective measure is lacking. Building on prior work, we examined the relationship between the receipt of dialysis ahead of schedule before the storm (also known as early dialysis) and adverse outcomes of patients with end-stage renal disease in the areas most affected by Hurricane Sandy. Retrospective cohort analysis, using claims data from the Centers for Medicare & Medicaid Services Datalink Project. Patients receiving long-term hemodialysis in New York City and the state of New Jersey, the areas most affected by Hurricane Sandy. Receipt of early dialysis compared to their usual treatment pattern in the week prior to the storm. Emergency department (ED) visits, hospitalizations, and 30-day mortality following the storm. Of 13,836 study patients, 8,256 (60%) received early dialysis. In unadjusted logistic regression models, patients who received early dialysis were found to have lower odds of ED visits (OR, 0.75; 95% CI, 0.63-0.89; P=0.001) and hospitalizations (OR, 0.77; 95% CI, 0.65-0.92; P=0.004) in the week of the storm and similar odds of 30-day mortality (OR, 0.80; 95% CI, 0.58-1.09; P=0.2). In adjusted multivariable logistic regression models, receipt of early dialysis was associated with lower odds of ED visits (OR, 0.80; 95% CI, 0.67-0.96; P=0.01) and hospitalizations (OR, 0.79; 95% CI, 0.66-0.94; P=0.01) in the week of the storm and 30-day mortality (OR, 0.72; 95% CI, 0.52-0.997; P=0.048).

The rebirth of interest in renal tubular function.

Lowenstein, Jerome; Grantham, Jared J

The measurement of glomerular filtration rate by the clearance of inulin or creatinine has evolved over the past 50 years into an estimated value based solely on plasma creatinine concentration. We have examined some of the misconceptions and misunderstandings of the classification of renal disease and its course, which have followed this evolution. Furthermore, renal plasma flow and tubular function, which in the past were estimated by the clearance of the exogenous aryl amine, para-aminohippurate, are no longer measured. Over the past decade, studies in experimental animals with reduced nephron mass and in patients with reduced renal function have identified small gut-derived, protein-bound uremic retention solutes ("uremic toxins") that are poorly filtered but are secreted into the lumen by organic anion transporters (OATs) in the proximal renal tubule. These are not effectively removed by conventional hemodialysis or peritoneal dialysis. Residual renal function, urine produced in patients with advanced renal failure or undergoing dialysis treatment, may represent, at least in part, secretion of fluid and uremic toxins, such as indoxyl sulfate, mediated by proximal tubule OATs and might serve as a useful survival function. In light of this new evidence of the physiological role of proximal tubule OATs, we suggest that measurement of renal tubular function and renal plasma flow may be of considerable value in understanding and managing chronic kidney disease. Data obtained in normal subjects indicate that renal plasma flow and renal tubular function might be measured by the clearance of the endogenous aryl amine, hippurate.

Few studies have investigated the management of human immunodeficiency virus (HIV)-associated end-stage renal failure particularly in low-resource settings with limited access to renal replacement therapy. We aimed to evaluate the effects of HIV infection on continuous ambulatory peritoneal dialysis (CAPD)-associated peritonitis outcomes and technique failure in highly active antiretroviral therapy (HAART)-treated HIV-positive CAPD populations. We conducted a single-center prospective cohort study of consecutive incident CAPD patients recruited from two hospitals in Durban, South Africa from September 2012-February 2015. Seventy HIV-negative and 70 HIV-positive end-stage renal failure patients were followed monthly for 18 months at a central renal clinic. Primary outcomes of peritonitis and catheter failure were assessed for the first 18 months of CAPD therapy. We assessed risk factors for peritonitis and catheter failure using Cox regression survival analysis. The HIV-positive cohort had a significantly increased rate of peritonitis compared to the HIV-negative cohort (1.86 vs. 0.76 episodes/person-years, respectively; hazard ratio [HR], 2.41; 95% confidence interval [CI], 1.69-3.45, P peritonitis rate rose to 3.69 episodes/person-years (HR 4.54, 95% CI 2.35-8.76, P peritonitis rate of 1.60 episodes/person-years (HR 2.10, CI 1.39-3.15, P = 0.001). HIV was associated with increased hazards of peritonitis relapse (HR, 3.88; CI, 1.37-10.94; P = 0.010). Independent predictors associated with increased peritonitis risk were HIV (HR, 1.84; CI, 1.07-3.16; P = 0.027), diabetes (HR, 2.09; CI, 1.09-4.03; P = 0.027) and a baseline CD4 count Peritonitis (HR, 14.47; CI, 2.79-75.00; P = 0.001), average hemoglobin concentrations (HR, 0.75; CI, 0.59-0.95; P = 0.016), and average serum C-reactive protein levels were independent predictors of catheter failure.

Viscosity, an important determinant of microcirculatory hemodynamics, is related to hematocrit (HCT), and may be altered by renal failure or its treatment. To assess these factors, we studied the effect of dialysis on the viscosity of whole blood, plasma, and reconstituted 70% HCT blood of eight continuous ambulatory peritoneal dialysis (CAPD) and nine hemodialysis (HD) patients under steady shear flow conditions at different shear rates, before and after dialysis, compared with nine normal subjects. The density of the red blood cells (RBCs), a marker of cell hydration, was measured in HD patients by a nonaqueous differential floatation technique. Whole blood viscosity was higher in controls than patients, and correlated with HCT before treatment (P less than 0.05) at shear rates of 11.5 to 230 s-1) in HD patients, and 23 to 230 s-1 in all end-stage renal disease (ESRD) patients. In contrast, whole blood viscosity correlated with HCT in CAPD patients only at the lowest shear rates (2.3 and 5.75 s-1, P less than 0.05). Plasma viscosity was higher in CAPD patients than both HD patients before treatment and controls (P less than 0.05, analysis of variance [ANOVA]), despite lower plasma total protein, albumin, and similar fibrinogen concentration compared with HD patients. When all samples were reconstituted to 70% HCT, CAPD patients had higher whole blood viscosity than control subjects'. The high HCT blood viscosity of the ESRD patients was higher than control subjects' at capillary shear rates, suggesting increased RBC aggregation and decreased RBC deformability in patients with renal disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Advanced mechanical circulatory support is increasingly being used with more sophisticated devices that can deliver pulsatile rather than continuous flow. These devices are more portable as well, allowing patients to await cardiac transplantation in an outpatient setting. It is known that patients with renal failure are at increased risk for developing worsening acute kidney injury during implantation of a ventricular assist device (VAD) or more advanced modalities like a total artificial heart (TAH). Dealing with patients who have an implanted TAH who develop renal failure has been a challenge with the majority of such patients having to await a combined cardiac and renal transplant prior to transition to outpatient care. Protocols do exist for VAD implanted patients to be transitioned to outpatient dialysis care, but there are no reported cases of TAH patients with end stage renal disease (ESRD) being successfully transitioned to outpatient dialysis care. In this report, we identify a patient with a TAH and ESRD transitioned successfully to outpatient hemodialysis and maintained for more than 2 years, though he did not survive to transplant. It is hoped that this report will raise awareness of this possibility, and assist in the development of protocols for similar patients to be successfully transitioned to outpatient dialysis care. © 2017 International Society for Hemodialysis.

Full Text Available The prevalence and incidence of Chronic Renal Failure [CRF] is increasing in the world. The main way for treatment of End-Stage Kidney Disease [ESKD] - that leads from CRF - is hemodialysis. One of the most important criteria for the evaluation of hemodialysis treatment process is the measure of dialysis adequacy. Dialysis adequacy is considered to the best therapeutic indicator for patient's clinical results and the best index for the assessment of the dialysis adequacy is the urea clearance. Although adherence accurate diet by patients is complement for hemodialysis and it is recommended for effectively control of symptoms of uremic syndrome and preventing longterm complications, many of these patients do not keep diet and fluid restriction and result in non-adequate dialysis, therefore, in order to improve dialysis adequacy, education, justify and emend patient’s attitude about diet necessity of following dialysis period times precisely and on time refers are very important. Due to the complexity of the treatment and care of hemodialysis patients, as well as the needs for adequate dialysis implement for to achieve effective treatment for these patients, by designing and run an educational program based on Health Education Models, dialysis adequacy can be improved.

The incidence rate of renal replacement therapy (RRT) for end-stage renal disease (ESRD) is decreasing in several countries, but not in France. We studied the RRT trends in mainland France from 2005 to 2014 to understand the reasons for this discrepancy and determine the effects of ESRD management changes. Data were extracted from the French Renal Epidemiology and Information Network registry. Time trends of RRT incidence and prevalence rates, patients' clinical and treatment characteristics were analysed using the Joinpoint regression program and annual percentage changes. Survival within the first year of RRT was analysed using Kaplan-Meier estimates for 4 periods of time. The overall age- and gender-adjusted RRT incidence rate increased from 144 to 159 individuals per million inhabitants (pmi) (+0.8% per year; 95% CI: 0.5-1.2) and the prevalence from 903 to 1141 pmi (+2.4% per year; 95% CI: 2.2-2.7). This increase concerned exclusively ESRD associated with type 2 diabetes (+4.0%; 3.4-4.6) and mostly elderly men. Despite patient aging and increasing comorbidity burden and a persistent 30% rate of emergency dialysis start, the one-year survival rate slightly improved from 82.1% (81.4-82.8) to 83.8% (83.3-84.4). Pre-emptive wait listing for renal transplantation and the percentage of wait-listed patients within one year after dialysis start strongly increased (from 5.6% to 15.5% and from 29% to 39%, respectively). Kidney transplantation and survival significantly improved despite the heavier patient burden. However, the rise in type 2 diabetes-related ESRD and the stable high rate of emergency dialysis start remain major issues. Copyright © 2016 Association Société de néphrologie.

Prune belly syndrome (PBS) is a rare congenital syndrome characterized by hypoplasia of the abdominal muscles, urinary tract malformations, and cryptorchidism in males. The estimated incidence is 1 in 35,000 to 50,000 live births. Chronic renal failure and end-stage renal disease (ESRD), due both to different degrees of renal hypoplasia or dysplasia and infectious complications, develops in 20-30% of patients who survive the neonatal period. No data are available on progression time to ESRD, owing to the variability of the phenotypic features of nephropathy. Nevertheless, PBS is primarily a pathology of pediatric interest as demonstrated, for example, by the reported average age at transplantation which usually does not exceed fifteen years of age. Therefore the need for renal replacement therapy (RRT) in adult patients with PBS is unusual. It is reasonable to suppose that the abdominal muscular defects may represent a limit for peritoneal dialysis (PD) utilization in PBS adult patients in many Kidney Units where, conversely, treatment with hemodialysis would be probably the easier choice. Here we describe the case of a 44 -year- old man with PBS who, at the age of 41, required RRT and was faced with the challenge of accepting PD. After more than three years of nocturnal automated peritoneal dialysis treatment we can safely say, as the following case illustrates, that PD is a feasible option in PBS adult patients.

Full Text Available BACKGROUND: Patients started on long term hemodialysis have typically had low rates of reported renal recovery with recent estimates ranging from 0.9-2.4% while higher rates of recovery have been reported in cohorts with higher percentages of patients with acute renal failure requiring dialysis. STUDY DESIGN: Our analysis followed approximately 194,000 patients who were initiated on hemodialysis during a 2-year period (2008 & 2009 with CMS-2728 forms submitted to CMS by dialysis facilities, cross-referenced with patient record updates through the end of 2010, and tracked through December 2010 in the CMS SIMS registry. RESULTS: We report a sustained renal recovery (i.e no return to ESRD during the available follow up period rate among Medicare ESRD patients of > 5% - much higher than previously reported. Recovery occurred primarily in the first 2 months post incident dialysis, and was more likely in cases with renal failure secondary to etiologies associated with acute kidney injury. Patients experiencing sustained recovery were markedly less likely than true long-term ESRD patients to have permanent vascular accesses in place at incident hemodialysis, while non-White patients, and patients with any prior nephrology care appeared to have significantly lower rates of renal recovery. We also found widespread geographic variation in the rates of renal recovery across the United States. CONCLUSIONS: Renal recovery rates in the US Medicare ESRD program are higher than previously reported and appear to have significant geographic variation. Patients with diagnoses associated with acute kidney injury who are initiated on long-term hemodialysis have significantly higher rates of renal recovery than the general ESRD population and lower rates of permanent access placement.

In chronic renal failure (CRF), deterioration of glomerular filtration results in accumulation of metabolites in the body which affect all organs. This study was performed to investigate the olfactory functions, and determine if hemodialysis or peritoneal dialysis improves olfactory function in non-diabetic CRF patients. The olfactory functions were analyzed in CRF patients not on a dialysis program and had a creatinine level≥2mg/dL, in CRF patients on hemodialysis or peritoneal dialysis, and in healthy controls. Diabetic patients were excluded since diabetes alone is a cause of olfactory dysfunction. The study group consisted of a total of 107 individuals including 38CRF patients on a hemodialysis program, 15 CRF patients on peritoneal dialysis, 30 patients with a creatinine level ≥ 2mg/dL without any need for dialysis, and 24 healthy controls with normal renal functions. Olfactory functions were analyzed with "Sniffin' sticks" test, and the groups were compared for the test results. All test parameters were impaired in patients with CRF. The median TDI scores of the patients with CRF and the healthy subjects were 24.75 (13-36) and 32.5 (27.75-37.75), respectively, with a statistically significant difference in between (P<0.001). The olfactory functions for the dialysis patients were better than those for the CRF patients not on a dialysis program (P=0.020). Non-diabetic CRF affects olfactory functions negatively. Dialysis improves olfactory functions in those patients. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Full Text Available Continuous renal replacement therapy (CRRT is one of the dialysis modalities for critically ill patients. Despite intensive dialysis care, a high mortality rate is found in these patients. Our objective was to investigate the factors associated with poor outcomes in these patients. We conducted a retrospective cohort study using the National Health Insurance Research Database. Records of critically ill patients who received CRRT between 2007 and 2011 were retrieved, and the patients were categorized into two groups: those with acute kidney injury (AKI and those with history of end-stage renal disease (ESRD. Our primary and secondary outcomes were in-hospital mortality and long-term survival and non-renal recovery (long-term dialysis dependence, respectively, in the AKI group. We enrolled 15,453 patients, with 13,204 and 2249 in the AKI and ESRD groups, respectively. Overall, 66.5% patients died during hospitalization. In-hospital mortality did not differ significantly between groups (adjusted odds ratio, 0.93; 95% CI, 0.84-1.02. Age, chronic liver disease, and cancer history were identified as independent risk factors for in-hospital mortality in both groups. Hypertension was associated with higher risk of in-hospital mortality in patients with AKI. Age, coronary artery disease, and admission to the medical intensive care unit (MICU were risk factors for long-term dialysis dependence in patients with AKI. Patients with AKI and ESRD have similarly poor outcomes after CRRT. Older age and presence of chronic liver disease and cancer were associated with higher mortality. Older age, presence of coronary artery disease, and admission to MICU were associated with lower renal recovery rate in patients with AKI.

Full Text Available Background: Laparoscopic techniques for the placement of peritoneal dialysis catheters are becoming increasingly popular. Recently, with the improvements in laparoscopic surgery, various methods for the insertion of peritoneal dialysis catheters have been reported, indicating that the laparoscopic insertion is preferred over the open and percutaneous techniques. The aim of this study was to introduce and assess a simplified laparoscopic method for the insertion of peritoneal dialysis catheters in continuous ambulatory peritoneal dialysis (CAPD patients.Methods: We enrolled 79 consecutive end-stage renal patients (46 men and 33 women with a mean age of 50 years (range: 19-83 years in this study. During the surgery, a 5-mm trocar was placed in the left upper quadrant for the optics and another 5-mm trocar was placed to the left of the umbilicus. Using the second trocar, a tunnel was formed 2 cm left of the umbilical plane for the insertion of a Tenckhoff catheter. Under direct vision, the catheter was advanced into the abdomen. The catheter was tested for patency. Catheters of all subjects were capped for two weeks before dialysis initiation.Results: The mean duration of the operation was 15 minutes. Ten patients died during the follow-up period, all due to other medical problems, and six patients underwent renal transplantation; however, no deaths or complications were observed during surgery. Early onset complications were seen in 12 patients (15.1%. The most frequent late-onset medical and mechanical complications were peritonitis (6.3% and hernia (3.7%. During a follow-up period of four years, removal of the catheter was required in two patients as a result of peritonitis.Conclusion: We obtained a low complication rate and a high catheter survival rate with this laparoscopic insertion of the Tenckhoff catheter. We believe future experience will encourage the use of this safe, simple and quick procedure.

The prevalence of end-stage renal disease is increasing worldwide. It is also one of the main health problems in Pakistan. Currently, hemodialysis represents the main mode of treatment for patients with end-stage renal disease in this country. Despite 24-hour free dialysis at the Sindh Institute of Urology and Transplantation (Karachi, Pakistan), a significant number of patients do not turn up for regular dialysis or miss regular sessions of dialysis. We conducted this study to identify and highlight the factors leading to poor compliance with regular hemodialysis treatment despite free dialysis treatment offered at our center. In 2014, 4565 patients with end-stage renal disease were registered at the Sindh Institute of Urology and Transplantation. Among these, 610 patients (13.4%) missed more than 2 sessions of dialysis and were included in the present study. Patients provided written informed consent before study participation. Data were collected from a questionnaire survey and analyzed by SPSS software (SPSS: An IBM Company, version 20.0, Chicago, IL, USA). Despite 24-hour dialysis facilities, the patient drop-out rate (779; 18%) was high. In addition, a significant minority of patients (610; 13.4%) was erratic in adherence to maintenance hemodialysis schedules, with > 2 missed appointments. The mean age of these 610 patients was 33.4 ± 7.4 years, and 345 patients (57%) were males. The main factors leading to poor compliance included cost of travel (33.2%), lack of affordable lodging and boarding facilities near dialysis center (30.9%), long distances from dialysis center (20.1%), and lack of family support (15.6%). This study shows that there is significant drop-out and poor compliance rates for regular dialysis despite free dialysis facilities.

Full Text Available Peritoneal dialysis is an established form of renal replacement therapy used in many patients with end-stage renal disease. The key to a successful chronic peritoneal dialysis is a permanent and safe access to the peritoneal cavity. This study was conducted in order to evaluate the catheter survival and its related factors in Imam Khomeini Hospital. A total of 80 catheters were inserted into 69 patients (52 men and 28 women with end-stage chronic renal failure during a period of 84 months. Retrospectively the correlation between catheter survival (overall and event free with demographic factors (sex and age, surgical factors (surgeons and surgical methods, nephrologic factors (the causes of peritoneal dialysis selection and the history of hemodialysis and peritonitis factors (the history and number of peritonitis has been evaluated. The mean age of the patients was 48.35 years (16 to 79 years. The overall survival of catheters or the probability of having a functioning catheter after one, two and three years was 53%, 41%, 22%, respectively. The event free survival of the catheter or the probability of having a functioning catheter without any problems after one year was 14%. It has been found out that among all factors in this study only history of hemodialysis had statistically significant effect on the overall survival of continuous ambulatory peritoneal dialysis catheter (P = 0.04. It seems that the overall survival of catheters is better when CAPD is started before any other attempts for hemodialysis.

An implantable artificial kidney can markedly improve the quality of life of renal disease patients. Our group has developed an implantable multilayered dialysis system consisting of microfluidic channels and dialysis membranes. Long-term evaluation is necessary for implant devices where biofouling is a critical factor, culminating in the deterioration of dialysis performance. Our previous work revealed that surface conditions, which depend on the manufacturing process, determine the amount of biofouling, and that electrolytic etching is the most suitable technique for forming a channel wall free of biofouling. In this study, we investigated the electrolytic etching conditions in detail. We conducted in vitro experiments for 7 d and evaluated the adhesion of biomaterials by scanning electron microscopy. The experiments revealed that a surface mirror-finished by electrolytic etching effectively prevents biofouling.

Understanding health decisions using critical realism: home-dialysis decision-making during chronic kidney disease This paper examines home-dialysis decision making in people with Chronic Kidney Disease (CKD) from the perspective of critical realism. CKD programmes focus on patient education for self-management to delay the progression of kidney disease and the preparation and support for renal replacement therapy e.g.) dialysis and transplantation. Home-dialysis has clear health, societal and economic benefits yet service usage is low despite efforts to realign resources and educate individuals. Current research on the determinants of modality selection is superficial and insufficient to capture the complexities embedded in the process of dialysis modality selection. Predictors of home-dialysis selection and the effect of chronic kidney disease educational programmes provide a limited explanation of this experience. A re-conceptualization of the problem is required in order to fully understand this process. The epistemology and ontology of critical realism guides our knowledge and methodology particularly suited for examination of these complexities. This approach examines the deeper mechanisms and wider determinants associated with modality decision making, specifically who chooses home dialysis and under what circumstances. Until more is known regarding dialysis modality decision making service usage of home dialysis will remain low as interventions will be based on inadequate epistemology. © 2011 Blackwell Publishing Ltd.

Peritoneal dialysis is a new renal replacement therapy recently introduced in Morocco since 2006. Continuous ambulatory peritoneal dialysis has proven to be as effective as hemodialysis. However, it is associated with several complications. The aim of this study was to evaluate the outcome of complications in patients treated with peritoneal dialysis at our center. The nature of non-infectious complications was noted during follow-up in these patients. Fiftyseven complications were noted among 34 patients between June 2006 and June 2014. Catheter migration was the most common complication (36.8%), followed by obstruction (14%), dialysate leaks (14%), hemorrhagic complications (10.5%) and, finally, hernia (12.2%), catheter perforation (5.2%) and externalization (3.5%).

Withdrawal from dialysis is ethically appropriate for some patients with multiple comorbidities and a shortened life expectancy. Taiwan has the highest prevalence of dialysis patients in the world, and the National Health Insurance (NHI) program offers renal replacement therapy free of charge. In this review, we discuss its current status and many background issues related to withdrawing dialysis from patients with advanced renal failure in Taiwan. Compared with dialysis therapy, the medical resources for hospice care are relatively sparse. Since the announcement of the Statute for Palliative Care in 2000, there has been a gradual improvement in the laws and health polices supporting dialysis withdrawal. Culture and social customs also have a significant impact on the practice of hospice care. Based on current evidence and in accordance with the local environment, we propose recommendations for the clinical practice of dialysis withdrawal and hospice care. There remains a need to expand upon the community-based hospice care and home care systems to better serve patients. In conclusion, there are cross-cultural differences relating to dialysis withdrawal between Taiwan and Western countries. Our experience and clinical recommendations may be helpful for the countries with NHI systems or for the Eastern countries. Copyright © 2013. Published by Elsevier B.V.

Peritonitis is a serious problem in children receiving peritoneal dialysis. Campylobacter jejuni is an unusual cause of peritonitis. A 10-year-old boy who had end stage renal failure due to atypical hemolytic uremic syndrome was admitted to our hospital with abdominal pain and fever. Peritoneal dialysis fluid was cloudy and microscopic examination showed abundant leukocytes. Intraperitoneal cefepime treatment was started. Campylobacter jejuni was isolated from peritoneal dialysis fluid culture and oral clarithromycin was added to the treatment. At the end of therapy, peritoneal fluid culture was negative. To our knowledge, C. jejuni peritonitis was not reported in children previously. Although C. jejuni peritonitis is rarely encountered in children, it should be considered as an etiologic factor for peritonitis. Sociedad Argentina de Pediatría.

It has been reported in literature that self-esteem increases in patients who pass from continuous ambulatory peritoneal dialysis to renal transplantation. However, our clinical observations in the Department of Nephrology of Hospital Infantil de México Federico Gómez indicate otherwise. Therefore, we carried out this research on 60 patients, children and adolescents, male and female between the ages from 8 to 15 years old, and we applied them the Coopersmith self-esteem questionnaire, which has been validated in mexican population. These findings indicate that the social environment continuous ambulatory peritoneal dialysis patients feel more adapted than patients in renal transplant (p = 0.05). However it was also observed that these patients tried to show a better image on their situation through compensatory mechanisms (defense p = 0.03). It was concluded that it would be necessary to follow the adaptation of the transplanted patients, in order to help them achieve complete rehabilitation.

Multiple myeloma (MM) is a haematological tumour that is characterised by uncontrolled proliferation of plasma cells and a significant volume of serum free light chains (sFLCs), which can cause acute renal failure due to intratubular precipitation, resulting in cast nephropathy. Acute renal failure is a complication that can arise in more than 20% of patients with multiple myeloma, half of which will require dialysis. We report our experience with 13 patients who were treated with dialysis using high cut off filters (HCO) between July 2011 and February 2015. A total of 6 consecutive 6-hour sessions were performed using a 2.1 m(2) HCO filter (Theralite® by Gambro®). Afterwards, further 6-hour sessions were continued on alternate days. A total of 151 sessions were conducted, with an average of 11.6 sessions per patient (range 6-27). The treatment proved to be effective in removing both kappa and lambda sFLCs, resulting in a 93.7% fall in sFLCs by the end of treatment. The average reduction was 57.7% per dialysis session. 10 out of the 13 cases recovered sufficient renal function to become independent of dialysis. There were no major changes in albumin levels using an infusion protocol of 2 50-mL vials of 20% albumin at the end of the dialysis session. Combination treatment with chemotherapy and long dialysis with HCO filters was effective in reducing the sFLC levels and recovering sufficient renal function in 77% of cases. With HCO filters, significant cost savings are achieved, contrary to what was previously believed. Copyright © 2016 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U.

Cardiovascular morbidity and mortality risk factors in peritoneal dialysis patients

Directory of Open Access Journals (Sweden)

Jovanović Dijana B.

2008-01-01

Full Text Available Cardiovascular (CVS morbidity and mortality in the endstage renal disease (ESRD patients on peritoneal dialysis therapy is 10-30 folds higher than in general population. The prevalence of well known traditional risk factors such as age, sex, race, arterial hypertension, hyperlipidaemia, diabetes, smoking, physical inactivity is higher in the uraemic patients. Besides these, there are specific, nontraditional risk factors for dialysis patients. Mild inflammation present in peritoneal dialysis (PD patients which can be confirmed by specific inflammatory markers is the cause of CVS morbidity and mortality in these patients. Hypoalbuminaemia, hyperhomocysteinaemia and a higher level of leptin are important predictors of vascular complications as well as CVS events in the PD patients. Plasma norepinephrine, an indicator of sympathetic activity, is high in the ESRD patients and higher in the PD patients than in the patients on haemodialysis (HD. Therefore, norepinephrine may be a stronger risk factor in the PD patients. The same applies to asymmetric dimethylargine (ADMA, an endogenous inhibitor of nitric oxide synthase, which is an important risk factor of CVS morbidity and mortality 15 % higher in the PD than the HD patients. Hyperphosphataemia, secondary hyperparathyroidism and high calcium x phosphate product have been associated with the progression of the coronary artery calcification and valvular calcifications and predict all-cause CVS mortality in the PD patients. Residual renal function (RRF declines with time on dialysis but is slower in the PD than the HD patients. RRF decline is associated with the rise of proinflammatory cytokines and the onset of hypervolaemia and hypertension which increase the risk of CVS diseases, mortality in general and CVS mortality. In conclusion, it is very important to establish all CVS risk factors in the PD patients to prevent CVS diseases and CVS mortality in this population.

Radiological features of progressive tumoral calcinosis in chronic renal failure.

We present the case of a young adult patient with chronic renal failure who developed painful subcutaneous nodules after failed renal transplant and recommencing dialysis. These nodules were juxta-articular in location and initially located over both shoulders. Radiological evaluation suggested tumoral calcinosis. The patient was placed on a strict dialysis and dietary regimen but was suboptimally compliant with same. The patient developed progressive disease with an increase in size and number of juxta-articular calcified soft-tissue masses. However, 6 months following a second renal transplant clinical and radiological follow up demonstrated marked resolution both in symptomatology and radiographic findings. We present the plain radiographic, CT and MRI findings which demonstrate the typical radiological features of tumoral calcinosis. We correlate these findings with clinical course and histological findings following surgical excision of one of these masses.

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.

The United States Renal Data System (USRDS) began in 1989 through US Congressional authorization under National Institutes of Health competitive contracting. Its history includes five contract periods, two of 5 years, two of 7.5 years, and the fifth, awarded in February 2014, of 5 years. Over these 25 years, USRDS reporting transitioned from basic incidence and prevalence of end-stage renal disease (ESRD), modalities, and overall survival, as well as focused special studies on dialysis, in the first two contract periods to a comprehensive assessment of aspects of care that affect morbidity and mortality in the second two periods. Beginning in 1999, the Minneapolis Medical Research Foundation investigative team transformed the USRDS into a total care reporting system including disease severity, hospitalizations, pediatric populations, prescription drug use, and chronic kidney disease and the transition to ESRD. Areas of focus included issues related to death rates in the first 4 months of treatment, sudden cardiac death, ischemic and valvular heart disease, congestive heart failure, atrial fibrillation, and infectious complications (particularly related to dialysis catheters) in hemodialysis and peritoneal dialysis patients; the burden of congestive heart failure and infectious complications in pediatric dialysis and transplant populations; and morbidity and access to care. The team documented a plateau and decline in incidence rates, a 28% decline in death rates since 2001, and changes under the 2011 Prospective Payment System with expanded bundled payments for each dialysis treatment. The team reported on Bayesian methods to calculate mortality ratios, which reduce the challenges of traditional methods, and introduced objectives under the Health People 2010 and 2020 national health care goals for kidney disease.

The objective of the study was to understand the extent to which financial incentives such as Payment by Results and other payment mechanisms motivate kidney centres in England to change their practices. The study followed a qualitative design. Data collection involved 32 in-depth semistructured interviews with healthcare professionals and managers, focusing on their subjective experience of payment structures. Participants were kidney healthcare professionals, clinical directors, kidney centre managers and finance managers. Healthcare commissioners from different parts of England were also interviewed. Participants worked at five kidney centres from across England. The selection was based on the prevalence of home haemodialysis, ranging from low (8%) prevalence, with at least one centre in each one of these categories at the time of selection. While the tariff for home haemodialysis is not a clear incentive for its adoption due to uncertainty about operational costs, Commissioning for Quality and Innovation (CQUIN) targets and the Best Practice Tariff for vascular access were seen by our case study centres as a motivator to change practices. The impact of financial incentives designed at a policy level is influenced by the understanding of cost and benefits at the local operational level. In a situation where costs are unclear, incentives which are based on the improvement of profit margins have a smaller impact than incentives which provide an additional direct payment, even if this extra financial support is relatively small.

Managing mental illness in the dialysis treatment environment: a team approach.

Prescott, Megan

2006-12-01

Outpatient chronic hemodialysis facilities often serve large populations of patients in an open and sometimes fast-paced environment. Any sizeable group of people will contain a sample of mental illnesses -and the end-stage renal disease diagnosis can be accompanied by co-occurring or comorbid mental illness. Thus, it is important for professional teams to be able to effectively manage related issues arising in the dialysis clinic. Guided by Medicare mandates, dialysis clinics all employ a masters level social worker to respond to the myriad psychosocial needs of this population; MSWs are trained to recognize the signs and symptoms of mental illnesses, and can help guide the team response.

Platelet Levels and Implications For Pre-Dialysis Chronic Renal ...

African Journals Online (AJOL)

Platelet count is assumed to be normal in chronic renal insufficiency. However, the possible effect of loss of platelet function in chronic renal failure (CFR) in relation to occult chronic blood loss, haematuria and overall health of the patient has not been given the desired attention. The aim of this study was to determine the ...

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.

In recent years, the population of chronic dialysis has grown in number but also in age and frequency of co-morbidies such as cardiac diseases, vascular pathologies, diabetes, etc. The majority of patients on chronic hemodialysis are over 70 years and, given the high number of comorbidities, they often exhibit poor tolerance to dialysis treatments. A non-tolerated dialytic treatment can have side-effects that would require an intensification of the dialysis sessions and many hospitalizations. Consequently, the problematic dialysis treatments, as well as harmful for the patient, become economically more detrimental than other treatments apparently more expensive but more tolerated ones In the current days we have, thanks to the huge developments in dialysis technology, powerful weapons to ensure effective and scarcely symptomatic dialysis treatments to the majority of the HD patients. New, highly biocompatible membranes with defined and modular cut-off and / or absorption capacity may allow us to provide adequate purification. Moreover the monitoring and biofeedback systems such as blood volume tracking, body temperature monitoring (BTM) and blood pressure (BPM) can be very useful in reducing the risk of intra-dialytic hypotension and symptoms. Therefore, the dialytic therapy, as well as all the pharmacological therapies for the chronic patient, must consider the specificity of the patient, basing on his metabolic problems, cardiovascular tolerance, residual renal function and on his dietary and general compliance. The central aim of the nephrologist is to formulate the better prescription for the individual patient, considering the dialysis modalities, the membrane type, the dry weight (ideal post-dialysis body weight), the frequency and the duration of the weekly sessions and the technological tools that can optimize the treatment.

Peritoneal dialysis (PD) offers many advantages over hospital-based haemodialysis, including better quality of life. Despite this, there is a general under-utilisation of PD in Europe, which, to some extent, can be attributed to a lack of knowledge and education amongst renal clinicians and nurses. The specific aim of the European Training and Research in Peritoneal Dialysis (EuTRiPD) programme is to address this lack of knowledge, to develop a minimum of five biomarkers that allow the prediction of outcome in PD and three therapeutic treatments to improve outcome in PD. EuTRiPD is a EU-wide consortium with clinical, academic and commercial partners set up to address this knowledge gap. By training through research and close collaboration between academic and commercial entities we hope to improve the outcome and uptake of PD. It is the goal of EuTRiPD to improve the currently hampered diagnostic therapeutic developments in renal replacement therapy (RRT) and structure existing high-quality PD-related research across Europe. It is hoped that EuTRiPD can and will have a significant impact on socio-economic and scientific aspects of PD. It is the aim for EuTRiPD to boost the uptake of PD throughout Europe by making PD the obvious choice for patients. © 2013 European Dialysis and Transplant Nurses Association/European Renal Care Association.

The preference for dialysis modalities is not well understood in Japan. This study explored the subjective views of Japanese patients undergoing dialysis regarding their treatments. The participants were receiving in-center hemodialysis (CHD) or continuous ambulatory peritoneal dialysis (CAPD). In Study 1, 34 participants (17 CHD and 17 CAPD) were interviewed about the advantages and disadvantages of dialysis modalities. In Study 2, 454 dialysis patients (437 CHD and 17 CAPD) rated the advantages and disadvantages of CHD and CAPD in a cross-sectional survey. Interviews showed that professional care and dialysis-free days were considered as advantages of CHD, while independence, less hospital visits, and flexibility were considered as advantages of CAPD. Disadvantages of CHD included restriction of food and fluids and unpleasant symptoms after each dialysis session. Catheter care was an additional disadvantage of CAPD. Survey showed that the highly ranked advantages were professional care in CHD and less frequent hospital visits in CAPD, while the highly ranked disadvantages were concerns about emergency and time restrictions in CHD, and catheter care and difficulty in soaking in a bath in CAPD. The total scores of advantages and disadvantages showed that CHD patients subjectively rated their own modality better CHD over CAPD, while CAPD patients had the opposite opinion. The results of this study indicate that the factors affecting the decision-making process of Japanese patients are unique to Japanese culture, namely considering the trouble caused to the people around patients (e.g., families, spouses, and/or caregivers).

Chronic kidney disease (CKD) is associated with reduced health-related quality of life (HRQL). However, the relationship between pre-dialysis CKD, HRQL and clinical outcomes, including mortality and progression to end-stage renal disease (ESRD) is unclear. All 745 participants recruited into the Renal Impairment In Secondary Care study to end March 2014 were included. Demographic, clinical and laboratory data were collected at baseline including an assessment of HRQL using the Euroqol EQ-5D-3L. Health states were converted into an EQ-5Dindex score using a set of weighted preferences specific to the UK population. Multivariable Cox proportional hazards regression and competing risk analyses were undertaken to evaluate the association of HRQL with progression to ESRD or all-cause mortality. Regression analyses were then performed to identify variables associated with the significant HRQL components. Median eGFR was 25.8 ml/min/1.73 m2 (IQR 19.6-33.7ml/min) and median ACR was 33 mg/mmol (IQR 6.6-130.3 mg/mmol). Five hundred and fifty five participants (75.7%) reported problems with one or more EQ-5D domains. When adjusted for age, gender, comorbidity, eGFR and ACR, both reported problems with self-care [hazard ratio 2.542, 95% confidence interval 1.222-5.286, p = 0.013] and reduced EQ-5Dindex score [hazard ratio 0.283, 95% confidence interval 0.099-0.810, p = 0.019] were significantly associated with an increase in all-cause mortality. Similar findings were observed for competing risk analyses. Reduced HRQL was not a risk factor for progression to ESRD in multivariable analyses. Impaired HRQL is common in the pre-dialysis CKD population. Reduced HRQL, as demonstrated by problems with self-care or a lower EQ-5Dindex score, is associated with a higher risk for death but not ESRD. Multiple factors influence these aspects of HRQL but renal function, as measured by eGFR and ACR, are not among them.

Measured glomerular filtration rate at dialysis initiation and clinical outcomes of Indian peritoneal dialysis patients

Directory of Open Access Journals (Sweden)

Full Text Available The optimal time for dialysis initiation remains controversial. Studies have failed to show better outcomes with early initiation of hemodialysis; even a few had shown increased adverse outcomes including poorer survival. Few studies have examined the same in patients on peritoneal dialysis (PD. Measured glomerular filtration rate (mGFR not creatinine-based estimated GFR is recommended as the measure of kidney function in end-stage renal disease (ESRD patients. The objective of this observational study was to compare the outcomes of Indian patients initiated on PD with different residual renal function (RRF as measured by 24-h urinary clearance method. A total of 352 incident patients starting on chronic ambulatory PD as the first modality of renal replacement therapy were followed prospectively. Patients were categorized into three groups as per mGFR at the initiation of PD (≤5, >5–10, and> 10 ml/min/1.73 m2. Patient survival and technique survival were compared among the three groups. Patients with GFR of ≤5 ml/min/1.73 m2 (hazard ratio [HR] - 3.42, 95% confidence interval [CI] - 1.85–6.30, P = 0.000 and> 5–10 ml/min/1.73 m2 (HR - 2.16, 95% CI - 1.26–3.71, P = 0.005 had higher risk of mortality as compared to those with GFR of> 10 ml/min/1.73 m2. Each increment of 1 ml/min/1.73 m2 in baseline GFR was associated with 10% reduced risk of death (HR - 0.90, 95% CI - 0.85–0.96, P = 0.002. Technique survival was poor in those with an initial mGFR of ≤5 ml/min/1.73 m2 as compared to other categories. RRF at the initiation was also an important factor predicting nutritional status at 1 year of follow-up. To conclude, initiation of PD at a lower baseline mGFR is associated with poorer patient and technique survival in Indian ESRD patients.

The present report describes a case of a 64-year-old pre-dialysis woman with chronic kidney disease (CKD) stage 5, who developed severe hyperparathyroidism. This patient had been on a very low protein diet (VLPD) to delay the progression of CKD and the need for renal replacement therapy (RRT). Her serum calcium levels were high-normal to slightly high during this time. However, her serum intact parathyroid hormone (PTH) levels increased from 400 to 1160 pg/ml rapidly over a period of 3 months. Serum 1,25-(OH)2D levels were low, and ultrasound of the neck showed three markedly enlarged parathyroid glands exceeding 2 cm. Parathyroidectomy was performed, and all glands showed nodular hyperplasia, which indicated severe secondary hyperparathyroidism leading to tertiary. Severe secondary hyperparathyroidism requiring surgical intervention is usually observed in patients with long-term RRT and is relatively rare in the pre-dialysis patient. In this case, extension of the pre-dialysis period by VLPD may have predisposed this patient to develop severe secondary hyperparathyroidism. Thus, careful monitoring of calcium, phosphorus, and PTH may be necessary in patients treated with VLPD even before renal replacement therapy. Furthermore, initiation of dialysis should not be excessively delayed by strict protein restriction dietary therapy.

Radiologic features of a pyrophosphate-like arthropathy associated with long-term dialysis

In a series of 28 long-term dialysis patients with musculoskeletal complaints, the radiologic findings in six cases resembled those occurring in the arthropathy of idiopathic calcium pyrophosphate dihydrate deposition (CPPD) disease. These findings included osteophytes, subchondral cysts, and cartilage loss in the metacarpophalangeal joints, patellofemoral joints, wrists, and shoulders. Chondrocalcinosis was present in three of the six cases. There were no significant differences in renal function or levels of serum calcium, phosphorus, iron, ferritin, aluminum, or parathormone between these patients and a control group matched for sex and age. Long-term dialysis may be associated with a metabolic arthritis similar to the arthritis which occurs in CPPD deposition disease. The etiology may include deposition of CPPD crystals, hydroxyapatite, or other calcium-containing substances in joints, or it may be related to a number of dialysis-induced metabolic abnormalities.

Evidence is inconclusive on how best to guide the patient in decision-making around haemodialysis and peritoneal dialysis choice. International guidelines recommend involvement of the patient in the decision to choose the dialysis modality most suitable for the individual patient. Nevertheless, studies have shown lack of involvement of the patient in decision-making. To develop and pilot test an intervention for shared decision-making targeting the choice of dialysis modality. This study reflects the first two phases of a complex intervention design: phase 1, the development process and phase 2, feasibility and piloting. Because decision aids were a part of the intervention, the International Patient Decision Aid Standards were considered. The pilot test included both the intervention and the feasibility of the validated shared decision-making questionnaire (SDM Q9) and the Decision Quality Measure (DQM) applied to evaluate the intervention. A total of 137 patients tested the intervention. After the intervention, 80% of the patients chose dialysis at home reflecting an increase of 23% in starting dialysis at home prior to the study. The SDM Q9 showed the majority of the patients experienced this intervention as shared decision-making. An intervention based on shared decision-making supported by decision aids seemed to increase the number of patients choosing home dialysis. The SDM Q9 and DQM were feasible evaluation tools. Further research is needed to gain insight into the patients' experiences of involvement and the implications for their choice of dialysis modality. © 2018 European Dialysis and Transplant Nurses Association/European Renal Care Association.

During the last 20 years, waiting lists for renal transplantation (RT) have grown significantly older. However, elderly patients (ie ≥65 years of age) are still more rarely referred or accepted to waiting lists and, if enlisted, have less chances of actually receiving a kidney allograft, than younger counterparts. In this review, we looked at evidence for the benefits and risks of RT in the elderly trying to answer the following questions: Should RT be advocated for elderly patients? What should be the criteria to accept elderly patients on the waiting list for RT? What strategies might be used to increase the rate of RT in waitlisted elderly candidates? For selected elderly patients, RT was shown to be superior to dialysis in terms of patient survival. Virtually all guidelines recommend that patients should not be deemed ineligible for RT based on age alone, although a short life expectancy generally might preclude RT. Concerning the assessment of comorbidities in the elderly, special attention should be paid to cardiac evaluation and screening for malignancy. Comorbidity scores and frailty assessment scales might help the decision making on eligibility. Psychosocial issues should also be evaluated. To overcome the scarcity of organ donors, elderly RT candidates should be encouraged to consider expanded criteria donors and living donors, as alternatives to deceased standard criteria donors. It has been demonstrated that expanded criteria donor RT in patients 60 years or older is associated with higher survival rates than remaining on dialysis, whereas living donor RT is superior to all other options.

When patients start dialysis, their employment rate declines and disability benefits are an option. With patient sociodemographic and clinical characteristics including disability income status controlled, we investigated the significance of depressed mood and usual activity level as predictors of patients' continued employment after dialysis start. Incident patients from 296 randomly selected dialysis clinics were surveyed in the Comprehensive Dialysis Study (CDS). Participants provided information about employment status, disability income status, education, depressive symptoms measured by the Patient Health Questionnaire-2 (PHQ-2), and usual activity level/energy expenditure measured by the Human Activity Profile. Age, gender, race, insurance, diabetes, inability to ambulate or transfer, chronic obstructive pulmonary disease, cardiovascular conditions, and hemoglobin and serum albumin values at treatment start were obtained from US Renal Data System files. Dialysis modality was defined at time of interview. Among 585 CDS participants who worked in the previous year, 191 (32.6%) continued working after dialysis start. On the basis of the PHQ-2 cutoff score ≥3, 12.1% of patients who remained employed had possible or probable depression, compared with 32.8% of patients who were no longer employed. In adjusted analyses, higher Human Activity Profile scores were associated with increased likelihood of continued employment, and there was a borderline association between lower PHQ-2 scores and continued employment. Screening and management of depressive symptoms and support for increased activity level may facilitate patients' opportunity for continued employment after dialysis start, along with generally improving their overall quality of life.

Objective: Modern iodinated non-ionic contrast agents (CAs) can be classified based on their molecular structure into monomeric and dimeric CAs and have at comparable iodine concentrations a different viscosity and osmolality. During their renal excretion, CAs are concentrated in the renal tubuli which might enhance the viscosity difference between monomeric and dimeric CAs. The viscosity of a CA might have an underestimated importance for renal safety, as suggested by recent publications. In this study, we investigated the viscosities of CAs at the concentrations expected to be present in renal tubules. This concentration process was simulated in vitro using dialysis. Furthermore, we investigated urine viscosity and urine flow in rodents after administration of several non-ionic monomeric and dimeric CAs. Materials and methods: To estimate the viscosity of the CAs in vivo, we performed an in vitro dialysis of monomeric and dimeric CAs at various physiological osmolalities of the renal tubulus (290, 400, 500, 700 and 1000 mOsm/kg H 2 O). Following the dialysis, the iodine concentrations and the viscosities of the CAs were determined. Furthermore, to investigate the concentration process in vivo, we measured the urine viscosity and the urine flow in Han Wister rats after the administration of Iopromide, Iohexol, Ioversol, Iomeprol, Iodixanol, and Iosimenol at comparable iodine concentrations. As a control, saline was injected at the same volume. Results: In vitro dialysis of the dimeric CA increased the iodine concentration and strongly increased the viscosity at all tested osmolalities. In contrast, for the monomeric agents an increase in concentration and viscosity was observed only at 700 as well 1000 mOsm/kg H 2 O but to a lesser extent. In summary, dialysis strongly enhanced the viscosity differences between the non-ionic monomeric and dimeric CAs. The administration of dimeric CAs leads to a strong increase in urine viscosity; this was not observed for the

Massive hydrothorax complicating continuous ambulatory peritoneal dialysis (CAPD) is relatively rare. A 67-year-old male and a 23-year-old female patients during CAPD presented massive pleural effusion, They have been performing peritoneal dialysis due to end-stage renal disease for 8 months and 2 weeks respectively. We injected '9 9m Tc-labelled radiopharmaceutical (phytate and MAA, respectively) into peritoneal cavity with the dialysate. The anterior, posterior and right lateral images were obtained. The studies reveal visible radioactivity in the right chest indicating the communication between the peritoneal and the pleural space. After sclerotherapy with tetracycline, the same studies reveal no radioactivity in the right chest suggesting successful therapy. We think nuclear imaging is a simple and noninvasive method for the differential diagnosis of pleural effusion in patients during CAPD and the evaluation of therapy.

Full Text Available Care in dialysis is often associated with significant morbidity and mortality during the first year. Knowledge of its magnitude and causes could improve the prognosis of these patients. The aim of this study was to evaluate the survival and morbidity during the first year of dialysis for patients who initiated their dialysis between January 1, 2009 and December 31, 2009 and to study their possible correlation with baseline status at the beginning of treatment. A multi-center retrospective study was conducted in 11 dialysis centers. Clinical data at the beginning of dialysis and during the following year were collected. Mortality and morbidity risk factors were assessed by comparing different groups. Statistical analysis was performed with SPSS version 11. This study involved 134 patients, 79 men and 55 women, of whom 132 were on hemodialysis and two patients were on peritoneal dialysis. The mean age at initiation of treatment was 54.37 ± 18.09 years. Initial causes of nephropathy were dominated by diabetes (44.02% and hypertension (11.19%. Among these patients, 39.55% had never received prior nephrological follow-up and 64.92% had started renal replacement therapy on an emergency basis. The initial clinical state was dominated by the presence of hypertension (50.74%, diabetes (44.02%, coronary insufficiency (13.43% and heart failure (7.46%. Only 26.86% of the incident patients showed no comorbidity. During the first year of follow-up, 37.31% of the patients experienced at least one episode of comorbidity. Hospitalization was necessary in about half of these cases (17.91% of all patients. The overall mortality rate was 14.17%. One patient received a kidney transplant. The mortality rate in the first year of dialysis was lower in our study than in other series. Regular nephrological follow-up of these patients before they reach end-stage could have a significant influence on survival in dialysis.

Our objective was to examine management of mineral metabolism in patients wait-listed for renal transplant and to determine the impact on cardiac perfusion imaging.Methods: Data was collected retrospectively on patients wait-listed for a renal transplant (n = 105, being either active (n = 73 and on hold (n = 32. Demographic data, medications, serum concentrations of calcium, phosphate, parathyroid hormone, and cardiac perfusion imaging studies were collected from the electronic health record. Chi-square and Student’s t-tests were used to compare active and on-hold patients as appropriate. Logistic regression was used to examine variables associated with worsening cardiac imaging studies.Results: The wait-listed patients were of mean age 56 ± 14 years and had been on dialysis for 1329 ± 867 days. On-hold patients had received a significantly greater total dose of calcium (2.35 ± .94 kg versus 1.49 ± 1.52 kg; P = 0.02 and were more likely to have developed worsening cardiovascular imaging studies (P = 0.03. Total doses of calcium and calcitriol were associated with worsening cardiovascular imaging studies (P = 0.05.Conclusion: Patients on hold on the renal transplant waiting list received higher total doses of calcium. A higher total dose of calcium and calcitriol was also associated with worsening cardiovascular imaging. Time on dialysis before transplant has been associated with worse post-transplant outcomes, and it is possible that the total calcium and calcitriol dose

Little information is available on adherence to a home automated peritoneal dialysis (APD) prescription for children with end-stage renal disease. We have therefore retrospectively reviewed HomeChoice PRO Card data from patients Adherence was characterized as occurring ≥ 95%, 90-94%, or treatment adherence and patient age, gender, race and if the patient had received training, respectively, was assessed. Of the 51 patients (57% male), with a mean age at peritoneal dialysis (PD) onset of 11.8 ± 5.3 years, 28 (55%) were adherent for all variables. No difference in mean age or if patients were trained existed between the two groups. Males were more likely to be non-adherent (p = 0.026) as were African Americans (p = 0.048). The majority of patients were adherent to duration (96%) and number of cycles (92%), whereas non-adherence was more common with number of sessions (82%) and dialysate volume (78%). In conclusion, 45% of the pediatric patients in our study cohort exhibited some non-adherence to their prescribed APD regimen, emphasizing the value of closely monitoring the performance of home dialysis in children.

Since 2005, great progress has been made in health care provision to patients with terminal renal failure in Bolivia. Access to dialysis and transplantation is regulated by the Ministry of Health, based on clinical criteria, applied equitably, without favoritism or discrimination based on race, sex, economic means, or political power. Until December 2013, there were no restrictions in dialysis and transplantation in Health Insurance institutions, but they covered only 30% of the population. Now the remaining 70% has access to free dialysis funded by the communities where patients live, with funds coming from the government and taxes on oil products. More than 2,231 people are getting dialysis, reaching a population growth of >60% annually. The number of hemodialysis units has increased by >200% (60 units), making access easier for end-stage renal failure patients. Treatment protocols have been drawn up to guarantee the best quality of life for the patients. The Law on Donation and Transplantation was enacted in 1996, and Supplementary Regulations were enacted in 1997 with various amendments over the past 5 years. A National Transplant Coordination Board, working under the National Renal Health Program, supervises and regulates transplants and promotes deceased-donor transplantation in an attempt to cover the demand for donors. Rules have been drawn up for accreditation of transplant centers and teams to guarantee the best possible conditions and maximum guaranties. Since January 2014, the National Renal Health Program has been providing free kidney transplants from living donors. Copyright © 2016 Elsevier Inc. All rights reserved.

Abstract Hip fractures in older people requiring dialysis are associated with high mortality. Our study primarily aimed to evaluate the specific burden of dialysis on the mortality rate following hip fracture. The secondary aim was to clarify the effect of the fracture site on mortality. A retrospective cohort study was conducted using Taiwan's National Health Insurance Research Database to analyze nationwide health data regarding dialysis and non-dialysis patients ≥65 years who sustained a first fragility-related hip fracture during the period from 2001 to 2005. Each dialysis hip fracture patient was age- and sex-matched to 5 non-dialysis hip fracture patients to construct the matched cohort. Survival status of patients was followed-up until death or the end of 2011. Survival analyses using multivariate Cox proportional hazards models and the Kaplan-Meier estimator were performed to compare between-group survival and impact of hip fracture sites on mortality. A total of 61,346 hip fracture patients were included nationwide. Among them, 997 dialysis hip fracture patients were identified and matched to 4985 non-dialysis hip fracture patients. Mortality events were 155, 188, 464, and 103 in the dialysis group, and 314, 382, 1505, and 284 in the non-dialysis group, with adjusted hazard ratios (associated 95% confidence intervals) of 2.58 (2.13–3.13), 2.95 (2.48–3.51), 2.84 (2.55–3.15), and 2.39 (1.94–2.93) at 0 to 3 months, 3 months to 1 year, 1 to 6 years, and 6 to 10 years after the fracture, respectively. In the non-dialysis group, survival was consistently better for patients who sustained femoral neck fractures compared to trochanteric fractures (0–10 years’ log-rank test, P fractures was better than that of patients with trochanteric fractures only within the first 6 years post-fracture (0–6 years’ log-rank, P fracture patients. Survival outcome was better for non-dialysis patients with femoral neck fractures compared to those with

Patient satisfaction is an important aspect of dialysis care, only recently evaluated in clinical studies. We developed a tool to assess peritoneal dialysis (PD) customer satisfaction, and sought to evaluate and validate the Customer Satisfaction Questionnaire (CSQ), quantifying PD patient satisfaction. The CSQ included questions regarding administrative issues, Delivery Service, PD Training, Handling Requests, and transportation. The study was performed using interviews in all Hungarian Fresenius Medical Care dialysis centers offering PD. CSQ results were compared with psychosocial measures to identify if patient satisfaction was associated with perception of social support and illness burden, or depression. We assessed CSQ internal consistency and validity. Factor analysis explored potential underlying dimensions of the CSQ. One hundred and thirty-three patients treated with PD for end-stage renal disease for more than 3 months were interviewed. The CSQ had high internal consistency. There was high patient satisfaction with customer service. PD patient satisfaction scores correlated with quality of life (QOL) and social support measures, but not with medical or demographic factors, or depressive affect. The CSQ is a reliable tool to assess PD customer satisfaction. PD patient satisfaction is associated with perception of QOL. Efforts to improve customer satisfaction may improve PD patients' quantity as well as QOL.

admitted due to acute renal insufficiency in two children hospitals of Santiago de Cuba from December, 2006 to December, 2008. Authors analyzed the age, sex, etiology, renal replacement therapy, cause of parenteral feeding use, nutritional assessment according to Cuban percentile tables and anthropometry parameters (age, weight, height and parenteral nutrients support. RESULTS: Prerenal events were the cause of acute renal insufficiency in the 44,4% of cases and renal and postrenal ones in the 33,4% and 22,2%, respectively. As a renal depuration method we used the peritoneal dialysis in the 66,6% of cases and the hemodialysis in remainder. The main causes that justified the parenteral feeding were the surgical affections, hypercatabolic states, the digestive hemorrhage and the pancreatitis in a decreasing order. Four patients were assessed as of low weight. CONCLUSIONS: The average support of proteins and lipids was under the established nutritional supports and that of kilocalories was higher than recommended. It is essential to improve these parameters in the treatment of these patients.

A classification model was developed to simplify planning of personnel at dialysis centres. This model predicted the care burden based on dialysis characteristics. However, patient characteristics and different dialysis centre categories might also influence the amount of care time required. To determine if there is a difference in care burden between different categories of dialysis centres and if specific patient characteristics predict nursing time needed for patient treatment. An observational study. Two hundred and forty-two patients from 12 dialysis centres. In 12 dialysis centres, nurses filled out the classification list per patient and completed a form with patient characteristics. Nephrologists filled out the Charlson Comorbidity Index. Independent observers clocked the time nurses spent on separate steps of the dialysis for each patient. Dialysis centres were categorised into four types. Data were analysed using regression models. In contrast to other dialysis centres, academic centres needed 14 minutes more care time per patient per dialysis treatment than predicted in the classification model. No patient characteristics were found that influenced this difference. The only patient characteristic that predicted the time required was gender, with more time required to treat women. Gender did not affect the difference between measured and predicted care time. Differences in care burden were observed between academic and other centres, with more time required for treatment in academic centres. Contribution of patient characteristics to the time difference was minimal. The only patient characteristics that predicted care time were previous transplantation, which reduced the time required, and gender, with women requiring more care time. © 2017 European Dialysis and Transplant Nurses Association/European Renal Care Association.

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

Although most patients eventually reach this target, the time required varies substantially. This study aimed to determine whether length of time with below-target hemoglobin levels after dialysis initiation is associated with medical costs, and if so, whether intermediate factors underlie the associations. US patients initiating dialysis in 2002 were studied using the Centers for Medicare and Medicaid Services ESRD database. Anemia persistence (time in months with hemoglobin below 110 g/L was determined in a six-month entry period, and outcomes were assessed in the subsequent six-month follow-up period. The structural equation modeling technique was used to evaluate associations between persistent anemia and medical costs and to determine intermediate factors for these associations. The study included 28,985 patients. Mean per-patient-per-month medical cost was $6267 (standard deviation $5713 in the six-month follow-up period. Each additional month with hemoglobin below 110 g/L was associated with an 8.9% increment in medical cost. The increased cost was associated with increased erythropoietin use and blood transfusions, and increased rates of hospitalization and vascular access procedures in the follow-up period.

Renal transplantation is the treatment of choice for patients with chronic renal failure, which produces a dramatic improvement in the quality of life and survival rates, in comparison to long-term dialysis. Nowadays, new imaging modalities allow early diagnosis of complications, and thanks to the recent developments of interventional techniques, surgery may be avoided in most cases. Knowledge in the types of renal transplant complications is fundamental for a correct pre-operative planning. In this article, we described the most common or clinically relevant renal transplant complications and explained their interventional management.

The aim of this study is to analyze the body composition of patients receiving emergent dialysis and compare their body cell mass (BCM) and fat-free mass (FFM) with those of normal subjects. The care of patients receiving sporadic, emergent dialysis treatment is a growing public health concern and the magnitude of muscle wasting that occurs in this population is not known. We used a cross-sectional design with matching to determine differences in total body potassium--an indicator of both BCM and FFM--between emergent dialysis patients and healthy normal subjects. We studied 22 subjects using a 40K counter that measures BCM and FFM and compared them to controls after matching with sex, height and weight. In the matched comparison, BCM and FFM were significantly lower in subjects with end-stage renal disease (ESRD). Unadjusted BCM was 4.7 kg lower and FFM was 8.8 kg lower for those with ESRD compared to those without ESRD (p FFM (7.7 kg) in the ESRD subjects (p = 0.004). After adjusting for age, height, weight and gender, BCM and FFM were lower by 4.2 and 7.8 kg, respectively (p FFM loss over time was significant, with the ESRD subjects demonstrating 2.2 kg per year decline (p = 0.01). We conclude that among other consequences, muscle wasting indicated by decline in BCM and FFM is a significant concern in the growing emergent dialysis population. © 2015 S. Karger AG, Basel.

1982-01-01

The bone-mineral content (BMC) of the peripheral skeleton was measured in 53 chronic renal-failure patients on maintenance dialysis using the 125 I photon absorptiometry according to Cameron. 39.6% of the patients were found to have a clearly pathological calcium content in calcaneus and ulna (33%). In total BMC assessments 43.4% of the patients examined showed strongly reduced BMC values at two measurement sites at least. Average bone-mineral content was below the value of the corresponding normal groups in all age groups of the dialysis patients. In addition, a significant correlation was verified to exist between the calcium contents of calcaneus and ulna. A significant correlation was found as well between reduced BMC values and dialysis duration. The correlation between the increased serum level of alkaline phosphatase and the reduced mineral content of the skeleton was significant as well. A minor but not significant correlation existed between the increase of the parathormone (PTH) level in the serum and the decrease of calcium content in calcaneus and ulna. A good correlation was found when contrasting the results of visual roentgenography and the BMC values established by photodensitometry: the median BMC value of patients with clear pathological X-ray findings was significantly below the one of patients without pathological X-ray findings. However, photon absorptiometry is superior to the subjective evaluation of X-ray pictures in the early diagnosis of bone diseases involving bone-mineral loss. (orig.) [de

Quality of life of patients receiving dialysis has been rated as poor. To synthesize the views of Canadian patients on or nearing dialysis, and those who care for them. Secondary analysis of a survey, distributed through dialysis centres, social media and the Kidney Foundation of Canada. Pan-Canadian convenience sample. Patients, their caregivers and health-care providers. Text responses to open-ended questions on topics relevant to end-stage renal disease. Statements related to needs, beliefs or feelings were identified, and were analysed by thematic content analysis. A total of 544 relevant statements from 189 respondents were included for the thematic content analysis. Four descriptive themes were identified through the content analysis: gaining knowledge, maintaining quality of life, sustaining psychosocial wellbeing and ensuring appropriate care. Respondents primarily identified a need for more information, better communication, increased psychosocial and financial support for patients and their families and a strong desire to maintain their previous lifestyle. Convenience sample; questions were originally asked with a different intent (to identify patient-important research issues). Patients on or nearing dialysis and their caregivers identified four major themes, gaining knowledge, maintaining quality of life, sustaining psychosocial wellbeing and ensuring appropriate care, several of which could be addressed by the health care system without requiring significant resources. These include the development of patient materials and resources, or sharing of existing resources across Canadian renal programs, along with adopting better communication strategies. Other concerns, such as the need for increased psychosocial and financial support, require consideration by health care funders.

This study analysed the validity and reliability of a food frequency questionnaire designed for African-American patients with low literacy. This instrument was designed specifically to meet the need for a tool that was short, easy to understand, and met clinical reliability and validity standards. Assessing patient nutritional status and dietary intake is crucial to the care of patients in end stage kidney disease. The development of a quick and reliable nutritional assessment tool for patients with low literacy could increase nutritional counselling effectiveness and improve patient outcomes. The renal food frequency questionnaire (RFF) and a standard 24-hour recall were administered to a general population of African-American patients undergoing dialysis. Registered Dieticians and statistical analyses were used to validate the content and structural validity and reliability of the RFF to adequately measure dietary intake. The study sample consisted of 30 African-American patients who received dialysis treatment at a regional teaching hospital facility. The RFF was found to be a simple, easy to understand instrument with low reading complexity (grade level 4.4). Inter-rater reliability was found to be high (.81-1.00), and statistical analysis determined a high level of clinical validity. The RFF was found to be a valid dietary recall tool that is appropriate for patients with limited literacy. It was found to have acceptable reliability and validity when compared with a standard 24-hour recall and has potential for use as a dietary intake and monitoring tool in patients undergoing dialysis. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Uremia results in a characteristic breath odor (uremic fetor) which is largely due to its high ammonia content. Earlier studies have shown a strong correlation between breath ammonia and blood urea levels and a 10-fold reduction in breath ammonia after hemodialysis in patients with chronic kidney disease. Potential sources of breath ammonia include: (i) local ammonia production from hydrolysis of urea in the oropharyngeal and respiratory tracts by bacterial flora, and (ii) release of circulating blood ammonia by the lungs. While the effects of uremia and hemodialysis on breath ammonia are well known their effects on blood ammonia are unknown and were explored here. Blood samples were obtained from 23 hemodialysis patients (immediately before and after dialysis), 14 peritoneal dialysis patients, and 10 healthy controls. Blood levels of ammonia, creatinine, urea, and electrolytes were measured. No significant difference was found in baseline blood ammonia between hemodialysis, peritoneal dialysis and control groups. Hemodialysis procedure led to a significant reduction in urea concentration (P ammonia level in 10 of the 23 patients studied. Change in blood ammonia pre- and post-hemodialysis correlated with change in serum bicarbonate levels (r = 0.61, P ammonia levels after dialysis, there was a strong correlation with drop in mean arterial pressure (r = 0.88, P ammonia compared to the patients who manifested a fall in blood ammonia (124 ± 8 vs. 136 ± 6 mmHg respectively, P = 0.27). Fall in blood urea following hemodialysis in ESRD patients was paradoxically accompanied by a modest rise in blood ammonia levels in 43% of the patients studied, contrasting prior reported effects of hemodialysis on breath ammonia. In this subgroup of patients, changes in blood ammonia during hemodialysis correlated with rise in blood bicarbonate and fall in mean arterial blood pressure. © 2016 International Society for Hemodialysis.

Background Bacterial endocarditis in dialysis patients is associated with high mortality rates. The literature is limited regarding long-term outcomes of valvular replacement surgery and choice of prosthesis in dialysis patients with bacterial endocarditis. Methods and Results Dialysis patients hospitalized for bacterial endocarditis, 2004-2007, were studied retrospectively using data from the US Renal Data System. Long-term survival of patients undergoing valve replacement surgery with tissue or non-tissue valves was compared using the Kaplan-Meier method. A Cox proportional hazards model was used to identify independent predictors of mortality in patients undergoing valvular replacement surgery. During the study period, 11,156 dialysis patients were hospitalized for bacterial endocarditis and 1267 (11.4%) underwent valvular replacement surgery (tissue valve 44.3%, non-tissue valve 55.7%). In the valve replacement cohort, 60% were men, 50% white, 54% aged 45-64 years, and 36% diabetic. Estimated survival with tissue and non-tissue valves, respectively, at 0.5, 1, 2, and 3 years was 59% and 60%, 48% and 50%, 35% and 37%, and 25% and 30% (log rank P = 0.42). Staphylococcus was the predominant organism (66% of identified organisms). Independent predictors of mortality in patients undergoing valve replacement surgery included older age, diabetes as cause of end-stage renal disease, surgery during index hospitalization, staphylococcus as the causative organism, and dysrhythmias as a comorbid condition. Conclusions Valve replacement surgery is appropriate for well-selected dialysis patients with bacterial endocarditis, but is associated with high mortality rates. Survival does not differ with tissue or non-tissue prosthesis. PMID:23785002

Full Text Available Background: In peritoneal dialysis, technique failure is an important metric to be considered. This study was performed in order to identify the relationship between trajectories of serum albumin levels and peritoneal dialysis technique failure on end-stage renal disease patients according to diabetic status. Furthermore, this study was performed to reveal predictors of serum albumin and technique failure simultaneously. Methods: This retrospective cohort study included 300 (189 non-diabetic and 111 diabetic end-stage renal disease patients on continuous ambulatory peritoneal dialysis treated in Al-Zahra Hospital, Isfahan, Iran, from May 2005 to March 2015. Bayesian joint modeling was carried out in order to determine the relationship between trajectories of serum albumin levels and peritoneal dialysis technique failure in the patients according to diabetic status. Death from all causes was considered as a competing risk. Results: Using joint modeling approach, a relationship between trajectories of serum albumin with hazard of transfer to hemodialysis was estimated as −0.720 (95% confidence interval [CI], −0.971 to −0.472 for diabetic and −0.784 (95% CI, −0.963 to −0.587 for non-diabetic patients. From our findings it was showed that predictors of low serum albumin over time were time on peritoneal dialysis for diabetic patients and increase in age and time on peritoneal dialysis, history of previous hemodialysis, and lower body mass index in non-diabetic patients. Conclusion: The results of current study showed that controlling serum albumin over time in non-diabetic and diabetic patients undergoing continuous ambulatory peritoneal dialysis treatment can decrease risk of adverse outcomes during the peritoneal dialysis period.

Patients with anti-glomerular basement membrane (GBM) disease are at increased risk of morbidity and mortality from renal failure, pulmonary haemorrhage or complications of treatment. One-third also have circulating anti-neutrophil cytoplasmic antibodies (ANCA). The aim of this study was to determine the clinicopathologic predictors of patient and renal outcomes in anti-GBM disease with or without ANCA. Retrospective review of 43 patients diagnosed with anti-GBM disease over 20 years in two centres, including nine with dual anti-GBM and ANCA positivity. Renal biopsies from 27 patients were scored for the presence of active and chronic lesions. Dual-positive patients were almost 20 years older than those with anti-GBM positivity alone (P = 0.003). The overall 1-year patient and renal survivals were 88 and 16%, respectively. Oligoanuria at diagnosis was the strongest predictor of mortality; none of the 16 patients without oligoanuria died. In a Cox regression model excluding oligoanuria, age was the only other independent predictor of survival. Pulmonary haemorrhage and dialysis dependence did not influence mortality. Thirty-five of the forty-three (81%) patients required dialysis at presentation, including all nine dual-positive patients. Of them, only two (5.7%) regained renal function at 1 year. By logistic regression, oligoanuria at diagnosis and percentage of crescents were independent predictors of dialysis independence at 3 months. However, in biopsied patients, the presence of crescents (>75%) added little to the presence of oligoanuria in predicting dialysis independence. Histological activity and chronicity indices did not predict renal outcome. Two of the nine (22%) dual-positive patients relapsed compared with none of the anti-GBM alone patients. Seven patients received kidney transplants without disease recurrence. Oligoanuria is the strongest predictor of patient and renal survival while percentage of glomerular crescents is the only pathologic

Urea and creatinine are commonly used as biomarkers of renal function. Abnormal concentrations of these biomarkers are indicative of pathological processes such as renal failure. This study aimed to develop a model based on Raman spectroscopy to estimate the concentration values of urea and creatinine in human serum. Blood sera from 55 clinically normal subjects and 47 patients with chronic kidney disease undergoing dialysis were collected, and concentrations of urea and creatinine were determined by spectrophotometric methods. A Raman spectrum was obtained with a high-resolution dispersive Raman spectrometer (830 nm). A spectral model was developed based on partial least squares (PLS), where the concentrations of urea and creatinine were correlated with the Raman features. Principal components analysis (PCA) was used to discriminate dialysis patients from normal subjects. The PLS model showed r = 0.97 and r = 0.93 for urea and creatinine, respectively. The root mean square errors of cross-validation (RMSECV) for the model were 17.6 and 1.94 mg/dL, respectively. PCA showed high discrimination between dialysis and normality (95 % accuracy). The Raman technique was able to determine the concentrations with low error and to discriminate dialysis from normal subjects, consistent with a rapid and low-cost test.

Medical nutrition therapy in chronic kidney disease; from dialysis to transplant: A case report

Directory of Open Access Journals (Sweden)

Full Text Available Chronic kidney disease has direct implications in nutritional status, causing anorexia and muscular catabolism. These situations are frequent in kidney renal replacement therapy in which nutritional disorders and inflammatory mechanisms associated with therapy often lead to the development of protein-energy wasting. Nutrition therapy has shown an adequate therapeutic strategy to prevent and treat metabolic alterations, reducing surgical and nutritional complication risks in kidney transplantation patients. The current case reports nutritional intervention on a continuous ambulatory peritoneal dialysis patient who was subsequently prescribed to automatic peritoneal dialysis and, finally, kidney transplant from a living donor.

Reported treatment adherence rates of patients with end stage renal disease (ESRD) have been extremely varied due to lack of reliable and valid measurement tools. This study was conducted to develop and test an instrument to measure treatment adherence to hemodialysis (HD) attendance, medications, fluid restrictions, and diet prescription among patients with ESRD. This article describes the methodological approach used to develop and test the psychometric properties (such as reliability and validity) of the 46-item ESRD-Adherence Questionnaire (ESRD-AQ) in a cohort of patients receiving maintenance HD at dialysis centers in Los Angeles County. The ESRD-AQ is the first self-report instrument to address all components of adherence behaviors of patients with ESRD. The findings support that the instrument is reliable and valid and is easy to administer. Future studies are needed in a larger sample to determine whether additional modifications are needed.

The European Union has an established mechanism which enables patients with end-stage kidney disease (ESKD) to receive dialysis abroad, allowing them to benefit from the legal right to freedom of movement. The number of patients seeking dialysis abroad has increased in recent years and the Veneto Region of Italy, a major tourist destination, has made significant investment in providing tourist haemodialysis services. To understand the issues involved in providing dialysis services for tourists moving within the European Union, such as the experience of patients using the service, the challenges faced by professionals and patients and continuity of care. Semi-structured interviews. Interviews were conducted with patients, health professionals and key stakeholders in two dialysis centres set up for tourists in the Veneto Region's Local Health Authority 10. The study uncovered high levels of patient satisfaction and a positive impact on patients' quality of life. However, the service faces a number of challenges relating to accessibility, language barriers and continuity of care for the patient when leaving Veneto. The study also demonstrates the importance of coordinating care prior to the tourists' stay. Tourist dialysis centres are necessary to make the right to freedom of movement for patients with ESKD a reality. The findings suggest that communicating and coordinating high-quality care across borders in the EU may be facilitated by increased standardisation of norms and documents for continuity of care, such as care plans and discharge summaries. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Full Text Available Anti-glomerular basement membrane (GBM disease is a rare cause of acute renal failure and known to have bad prognosis regarding renal functions recovery and patient survival specially when diagnosed late and presents with severe renal failure that requires dialysis. We report a case of 11-year-old child with acute renal failure secondary to anti-GBM disease and associated with antineutrophil cytoplasmic antibody-positive vasculitis. He was treated with plasmapheresis, steroids, and cyclophosphamide with recovery of his kidney functions.

Surgical complications are estimated to be as high as 30%-40% during the first 8 weeks after implantation of peritoneal dialysis (PD) catheters. 70 PD catheters which were implanted by transplant surgeons in 61 children (median age 3.3years, range 0.01-15.5years, 31 boys and 30 girls) in 2009-2014 were retrospectively reviewed. The incidence of complications and revisions during the first 6months after implantation was analyzed depending on children's weight and diagnosis. 17 out of 70 catheters needed a surgical revision within 6months after implantation (24.3%). Peritonitis was the most common complication affecting 18.6% of peritoneal dialysis catheters followed by obstruction and dislocation, which it occurred in 9 (12.9%) and 7 (10%) catheters, respectively. Leakage (n=5) only occurred in children with a weight of less than 10kg. The total proportion of complications was higher in children with less than 10kg of weight (P<0.001). PD is safe in children with acute renal failure and older children with chronic renal failure; however children with a weight of less than 10kg are more likely to develop complications.

We report two patients with rheumatoid arthritis (RA) who were suspected of microscopic polyangiitis during maintenance dialysis. Case 1 was a 52-year-old woman with RA diagnosed at the age of 38 years and treated successfully with gold compounds. At the age of 43 years, she presented with progressive renal dysfunction and abnormal urine sediments, and a renal biopsy revealed crescentic nephritis with advanced glomerular sclerosis. Myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA) was not measured on that occasion. She reached end-stage renal failure within 4 months and started peritoneal dialysis. Eight years later, soon after she was switched to hemodialysis, she developed fever of unknown origin. MPO-ANCA was elevated to 37 EU, although there were no other signs or symptoms suggestive of vasculitis. After taking prednisolone orally (10 mg/day), her fever withdrew, and MPO-ANCA became undetectable. Case 2 was a 71-year-old woman with RA diagnosed at the age of 60 years and treated with gold compounds. She developed renal failure of unknown cause (no biopsy was performed), and started hemodialysis at the age of 69 years. One year later, she presented with fever and subsequently developed cough with hemoptysis. MPO-ANCA was elevated to 62 EU. Treatment with azathioprine 50 mg and prednisolone 35 mg daily brought remarkable clinical improvement, and MPO-ANCA became undetectable. These cases highlight the importance of measuring ANCA even in RA patients on dialysis who present with fever of unknown origin or with underlying kidney disease of uncertain etiology.

Bone radiotracer uptake in renal osteodystrophy was investigated in 35 dialysis patients by correlating the results of quantitative bone scintigraphy with those of biochemical and bone morphometric studies. There were highly significant correlations (P < 0.001) between the total skeletal activity and the biochemical (iPTH and alkaline phosphatase), and histologic parameters of hyperparathyroidism. These clinical results strongly suggest that increased bone turnover i.e. hyperparathyroidism, rather than osteomalacia is the major cause of increased skeletal uptake in renal osteodystrophy.

Fredrik Uhlin

2015-10-01

Full Text Available Background/Aims: Plasma concentrations of the N-terminal fragment of pro-brain natriuretic peptide (NT-proBNP are increased in end-stage renal disease. Improvement in hemodynamic stability has been reported when switching from hemodialysis (HD to on-line hemodiafiltration (ol-HDF. The aim of this study was to investigate plasma concentrations of NT-proBNP, BNP and neuropeptide Y (NPY during a 1-year follow-up, after a change from high-flux HD to postdilution ol-HDF. Additional variables were also studied, e.g. pulse wave velocity and ordinary clinical parameters. Method: We conducted a prospective, single-center study including 35 patients who were switched from HD to HDF. Plasma concentrations of NT-proBNP, BNP and NPY before and after dialysis were measured at baseline (i.e. HD and at 1, 2, 4, 6 and 12 months on HDF. Results: All three peptide levels decreased significantly during HD and HDF when comparing concentrations before and after dialysis. Mean absolute value (before/after and relative decrease (% before versus after dialysis was 13.697/9.497 ng/l (31% for NT-proBNP, 62/40 ng/ml (35% for BNP and 664/364 pg/l (45% for NPY. No significant differences were observed when comparing predialysis values over time. However, postdialysis NT-proBNP concentration showed a significant decrease of 48% over time after the switch to HDF. Conclusion: The postdialysis plasma levels of NT-proBNP, BNP and NPY decreased significantly during both dialysis modes when compared to before dialysis. The postdialysis lowering of NT-proBNP increased further over time after the switch to ol-HDF; the predialysis levels were unchanged, suggesting no effect on its production in the ventricles of the heart.

Protein supplementation with sports protein bars in renal patients.

Meade, Anthony

2007-05-01

Malnutrition prevalence in patients on dialysis is well established. The protein requirements for both hemodialysis and peritoneal dialysis have been documented elsewhere, including the Kidney Disease Outcomes Quality Initiative Clinical Practice Guidelines for Nutrition in Chronic Renal Failure. The clinical challenge is to assist patients in meeting these targets, especially in those with anorexia. Traditional supplements have included fluid, which is an issue for patients who are fluid restricted. The study objectives were to (1) investigate the range of sports protein supplements that may be suitable for patients on hemodialysis to use and (2) trial nonfluid protein supplements in patients on hemodialysis. Known manufacturers of sports protein bars and other sports supplements available in Australia were contacted for the nutrient breakdown of high-protein products, specifically potassium, protein, and phosphorus contents. As a result, selected high-protein sports bars (Protein FX, Aussie Bodies, Port Melbourne, Victoria, Australia) were used as an alternative to the more commonly used renal-specific fluid supplements (Nepro, Abbott Laboratories, Abbott Park, IL; Novasource Renal, Novartis Nutrition Corporation, Fremont, MI; and Renilon, Nutricia, Wiltshire, UK) in patients with poor nutritional status requiring supplementation. Patient satisfaction and clinical nutrition markers were investigated. The study took place at inpatient, in-center, and satellite hemodialysis settings in Adelaide, South Australia. A total of 32 patients (16 females and 16 males) with an average age of 62.9 years (range 32-86 years) undergoing hemodialysis (acute and maintenance) were included. Subjects were selected by the author as part of routine clinical nutrition care. Patients trialed sports protein bars as a protein supplement alone or in conjunction with other supplementary products. All patients were in favor of the trial, with 22 of 32 patients continuing with the protein

The Latin American Society of Nephrology and Arterial Hypertension's Dialysis and Transplant Registry was chartered in 1991. It collects information on ESRD and its treatment in 20 countries of the region. The prevalence of patients on renal replacement therapy (RRT) increased from 129 pmp in 1992 to 447 pmp in 2004; in 2004, 56% of the patients were on hemodialysis, 23% on peritoneal dialysis, and 21% had a functioning kidney graft. The highest rates of prevalence were reported in Puerto Rico (1027 pmp), Chile (686 pmp), and Uruguay (683 pmp). Hemodialysis was widely used, except in El Salvador, Mexico, Guatemala, Nicaragua, and the Dominican Republic, where peritoneal dialysis predominated. Incidence rate increased from 27.8 pmp to 147 pmp in the same period of observation; the lowest rate was reported in Guatemala (11.4 pmp) and the highest in Puerto Rico (337.4 pmp). Diabetes mellitus was the leading cause of renal failure in incident patients; the highest rates were reported in Puerto Rico (62.2%) and Mexico (60%). Forty-four percent of the incident population were older than 65 years. Access to renal replacement therapy was universal in Argentina, Brazil, Chile, Cuba, Puerto Rico, Uruguay, and Venezuela, while was restricted in other countries. Main causes of death in dialysis were cardiovascular (44%) and infectious disease (26%). The rate of renal transplantation increased from 3.7 pmp in 1987 to 14.5 in 2004; fifty-three percent of the organs came from cadavers. Overall, donation rate was 5.9 pmp. In conclusion, the prevalence and incidence rates have increased over the years, and diabetes mellitus has emerged as the leading cause of kidney disease in the region. Although the rate of kidney transplantation has increased, the number remains insufficient to match the growing demand. The implementation of renal health programs in the region is urgently needed.

Full Text Available Objective: To study the effect of Shenkang injection combined with hemodialysis treatment on renal function, renal anemia and cytokine levels in patients with chronic renal failure. Methods: A total of 68 patients with chronic renal failure who received hemodialysis treatment in our hospital during between October 2013 and February 2016 were selected and randomly divided into two groups, the observation group received Shenkang injection treatment in the process of dialysis, and the control group only received conventional symptomatic and supportive treatment. 8 weeks after treatment, serum was collected to determine the levels of renal function indexes, nutritional status indexes, anemia indexes and cytokines, and urine was collected to determine renal function indexes. Results: β2-MG, UA, Cr, phosphorus, IL-17, IL-23, CTGF, TGF-β1, FGF-2 and FGF-23 levels in serum as well as NGAL, KIM-1 and RBP levels in urine of observation group were significantly lower than those of control group, and TP, Alb, PA, calcium, Hb, EPO, Fe, TRF and FER levels in serum were significantly higher than those of control group. Conclusion: Shenkang injection combined with hemodialysis treatment helps to improve renal function, nutritional status and renal anemia, and reduce the synthesis of inflammation and renal interstitial fibrosis-related cytokines in patients with chronic renal failure.

The management of neonatal acute and chronic renal failure: A review.

Science.gov (United States)

Coulthard, Malcolm G

2016-11-01

Most babies with chronic renal failure are identified antenatally, and over half that are treated with peritoneal dialysis receive kidney transplants before school age. Most infants that develop acute renal failure have hypotension following cardiac surgery, or multiple organ failure. Sometimes the falls in glomerular filtration and urine output are physiological and reversible, and sometimes due to kidney injury, but (illogically) it is now common to define them all as having 'acute kidney injury'. Contrary to widespread opinion, careful interpretation of the plasma creatinine concentrations can provide sensitive evidence of early acute renal failure. Conservative management frequently leads to under-nutrition or fluid overload. Acute peritoneal dialysis is often technically fraught in very small patients, and haemotherapies have been limited by vascular access and anticoagulation requirements, the need to blood-prime circuits, and serious limitations in regulating fluid removal. Newer devices, including the Nidus, have been specifically designed to reduce these difficulties. Crown Copyright © 2016. Published by Elsevier Ireland Ltd. All rights reserved.

Australia's Northern Territory (NT) has the country's highest incidence and prevalence of kidney disease. Indigenous people from remote areas suffer the heaviest disease burden. Concerns regarding cost and sustainability limit the provision of dialysis treatments in remote areas and most Indigenous people requiring dialysis relocate to urban areas. However, this dislocation of people from their family, community and support networks may prove more costly when the broader health, societal and economic consequences for the individual, family and whole of government are considered. The Dialysis Models of Care Study is a large cross organisation mixed methods study. It includes a retrospective (2000-2014) longitudinal data linkage study of two NT cohorts: Renal Cohort 1- comprising approximately 2000 adults who received dialysis and Renal Cohort 2- comprising approximately 400 children of those adults. Linkage of administrative data sets from the Australian and New Zealand Dialysis and Transplant Registry, NT Departments of Health, Housing and Education by a specialist third party (SA/NT Datalink) will enable extraction of activity, financial and outcome data. Interviews with patients, clinicians and service providers, using a snowball technique, will canvass relevant issues and assist in determining the full costs and impacts of the five most used dialysis Models of Care. The study uses a mixed methods approach to investigate the quantitative and qualitative dimensions of the full costs and outcomes associated with the choice of particular dialysis models of care for any given patient. The study includes a large data linkage component that for the first time links health, housing and education data to fully analyse and evaluate the impact on patients, their families and the broader community, resulting from the relocation of people for treatment. The study will generate a large amount of activity, financial and qualitative data that will investigate health costs less

Full Text Available Previous studies have observed worse sleep quality in patients undergoing conventional dialysis as compared to daily dialysis. Our aim was to compare the sleep parameters of patients undergoing daily or conventional dialysis using an objective measure (actigraphy. This cross-sectional study was performed in three dialysis centers, including a convenience sample (nonprobability sampling of 73 patients (36 patients on daily hemodialysis and 37 patients on conventional hemodialysis. The following parameters were evaluated: nocturnal total sleep time (NTST, expressed in minutes; wake time after sleep onset (WASO, expressed in minutes; number of nighttime awakenings; daytime total sleep time (DTST, expressed in minutes; number of daytime naps; and nighttime percentage of sleep (% sleep. The Mini-Mental State Examination and the Beck Depression Inventory were also administered. The mean age was 53.4  ±  17.0 years. After adjustment of confounding factors using multiple linear regression analysis, no difference in actigraphy parameters was detected between the groups: NTST (p=0.468, WASO (p=0.88, % sleep (p=0.754, awakenings (p=0.648, naps (p=0.414, and DTST (p=0.805. Different from previous studies employing qualitative analysis, the present assessment did not observe an influence of hemodialysis modality on objective sleep parameters in chronic renal patients.

Full Text Available Acute renal failure (ARF is the acute loss of kidney function over hours or days, the etiology of which varies in different countries. The data on the etiology and outcome of ARF in Arab children is limited. Our objective was to define the causes and predictors of outcome of ARF in Kuwaiti children, and the variables determining their fitness for dialysis. A total of 32 children with ARF were evaluated regarding their demographic and clinical data, the cause of ARF and the co-morbidities. Data were analyzed to find the independent variables determining fitness for dia-lysis and outcome. Males comprised 62.5% of the study children; 46.9% of ARF cases were due to sepsis and 56.2% underwent renal replacement therapy (RRT. Univariate analysis showed that age, hemodynamic instability, use of vasopressors, multi-organ failure (MOF, and mechanical venti-lation contributed to fitness for dialysis. However, MOF was the only independent variable affecting fitness for dialysis. The overall mortality was 43.8%. Univariate analysis showed that age below 24-months, hemodynamic instability, use of vasopressors, fluid overload, need for mecha-nical ventilation, MOF and late referral to the nephrologist were associated with poor outcome. However, multivariate analysis documented MOF, and the time of nephrologists′ intervention as independent prognostic indicators. Our study suggests that sepsis was the major cause of pediatric ARF. RRT is the optimal treatment, and the only factor determining child′s fitness for dialysis is MOF.

End-stage renal disease in sub-Saharan and South Africa.

The major health problems in Africa are AIDS, tuberculosis, malaria, gastroenteritis and hypertension; hypertension affects about 20% of the adult population. Renal disease, especially glomerular disease, is more prevalent in Africa and seems to be of a more severe form than that found in Western countries. The most common mode of presentation is the nephrotic syndrome, with the age of onset at five to eight years. It is estimated that 2 to 3% of medical admissions in tropical countries are due to renal-related complaints, the majority being the glomerulonephritides. There are no reliable statistics for ESRD in all African countries. Statistics of the South African Dialysis and Transplant Registry (SADTR) reflect the patients selected for renal replacement therapy (RRT) and do not accurately reflect the etiology of chronic renal failure (CRF), where public sector state facilities will offer RRT only to patients who are eligible for a transplant. In 1994, glomerulonephritis was recorded as the cause of ESRD in 1771 (52.1%) and hypertension in 1549 (45.6%) of patients by the SADTR. In a six-year study of 3632 patients with ESRD, based on SADTR statistics, hypertension was reported to be the cause of ESRD in 4.3% of whites, 34.6% of blacks, 20.9% mixed race group and 13.8% of Indians. Malignant hypertension is an important cause of morbidity and mortality among urban black South Africans, with hypertension accounting for 16% of all hospital admissions. In a ten-year study of 368 patients with chronic renal failure in Nigeria, the etiology of renal failure was undetermined in 62%. Of the remaining patients whose etiology was ascertained, hypertension accounted for 61%, diabetes mellitus for 11% and chronic glomerulonephritis for 5.9%. Patients with CRF constituted 10% of all medical admissions in this center. Chronic glomerulonephritis and hypertension are principal causes of CRF in tropical Africa and East Africa, together with diabetes mellitus and obstructive

Star fruit (SF) is a commonly available fruit produced and eaten in tropical and subtropical countries. Since 1993, various reports have described neurotoxicity after eating SF, but this clinical condition remains unfamiliar. We aimed to describe this clinical entity, the role of renal dysfunction in this disorder, treatment strategies, and prognosis of patients with SF intoxication. We conducted a search of PubMed and Google Scholar databases from 1993 to 2016. We included reports describing patients with a clear history of SF ingestion with acute symptoms. We described the demographic characteristics, reported SF intake, treatments used, and outcomes. We reviewed totally 126 patients (male:female = 1.5:1) from 33 articles with mean age 54.4 ± 11 (range: 30-84). The most common symptom was hiccups (65%), whereas confusion and seizure were the most common symptoms associated with mortality (42% and 61%, respectively). Pre-intoxication renal function also affected mortality. While there was no mortality in patients with normal renal function (NRF), the mortality of patients among reported cases with chronic renal insufficiency and end-stage renal disease undergoing dialysis were 36% and 27%, respectively. With the inclusion of patients reported to have NRF, the overall mortality was 24%. Consistently, the number of SF consumed was substantially higher in the patients with NRF than those with renal functional impairment. The most common treatment strategy was hemodialysis (59%). Patients with impaired renal function were at higher risks of SF intoxication. Severe neurologic symptoms mandate immediate medical intervention because of the association between their occurrence and high mortalities. Toxin removal through dialysis, rather than symptomatic relief, seems to be beneficial to patient survival. Early and continuous dialysis appears to alleviate severe symptoms and prevent symptom rebounds.

Patients and Methods: Between 1979 and 1990, eight patients with biopsy-proven acute renal allograft rejection and failure of all other immunosuppressive measures (corticosteroids, ATG, ALG or OKT3) were treated with LGI. Retrospective analysis was conducted for this control group. Radiotherapy was performed with Co-60 up to a median total dose of 6.0 Gy (single doses: 1.5-2.0 Gy). Six of eight patients were dialysis dependent prior to irradiation. In addition a literature review was performed including most important textbooks, electronic databases (Medline, Embase, Science Citations Index), and the internet. Results: Two of eight patients experienced a clinical reversal of rejection and an improvement of renal function: serum creatinine decreased significantly. One patient remained free of dialysis with a functioning graft, the other had a recurrent rejection 2 months later and became dialysis dependent. The literature review showed, that adjuvant LGI has no advantage over conventional immunosuppression. However, in case of a drug refractory allograft rejection LGI restores long-term stable organ function in 13-60% of cases. (orig.) [de

Dialysis disequilibrium syndrome is a metabolic complication that can be caused by rapid removal of plasma urea during hemodialysis. Dialysis disequilibrium syndrome can lead to osmotic demyelinating syndrome. This case report describes one case of encephalopathy accompanied by dialysis disequilibrium syndrome with imaging findings acquired immediately after hemodialysis in a 55-year-old woman with chronic renal failure. The patient was observed to present repetitive seizures and sudden deterioration of consciousness immediately after hemodialysis. Shortly after the onset of symptoms, the patient underwent a CT scan. The imaging findings of the CT scan reveal symmetrical diffuse white matter edema of bilateral cerebral hemispheres that extends to the pons along the internal capsule. A follow-up MRI taken two years later shows that reversible changes without damage have occurred in the lesions. The patient can thus be seen to present symptoms characteristically associated with dialysis disequilibrium syndrome, while brain imaging reveals dif-fuse reversible brain edema.

Portugal was the first European country to introduce an integrated management of end-stage renal disease (IM ESRD). This new program integrates various dialysis services and products, which are reimbursed at a fixed rate/patient/week called "comprehensive price payment." This initiative restructured the delivery of dialysis services, the monitoring of outcomes, and the funding of renal replacement therapy. This article described the implementation of a new model of comprehensive provision of hemodialysis (HD) services and aimed to assess its impact on dialysis care. Quality assessments and reports of patient satisfaction, produced by the Ministry of Health since 2008, as well as national registries and reports, provided the data for this review. Indicators of HD services in all continental facilities show positive results that have successively improved along the period of 2009-2011, in spite of an average annual growth of 3% of the population under HD treatment. Mortality rates for HD patients were 12.7%, 12%, and 11%, respectively in 2009, 2010, and 2011; annual hospitalization rates were 4.9%, 3.8%, and 4.4% for the same years; key performance indicators showed averages above the reference values such as hemoglobin, serum phosphorus, eKt/V, water quality, number of days of hospitalization per patient per year, and number of weekly dialysis sessions. The financing analysis of IM ESRD demonstrates a sustained control of global costs, without compromising quality. The IM ERSD program is an innovative and quality-driven approach that benefits both dialysis patients and providers, contributing toward the rationalization of service provision and the efficient use of resources. © 2013 International Society for Hemodialysis.

The Latin American Dialysis and Renal Transplant Registry (RLADTR) was founded in 1991; it collects data from 20 countries which are members of Sociedad Latinoamericana de Nefrología e Hipertension. This paper presents the results corresponding to the year 2010. This study is an annual survey requesting data on incident and prevalent patients undergoing renal replacement treatment (RRT) in all modalities: hemodialysis (HD), peritoneal dialysis (PD) and living with a functioning graft (LFG), etc. Prevalence and incidence were compared with previous years. The type of renal replacement therapy was analyzed, with special emphasis on PD and transplant (Tx). These variables were correlated with the gross national income (GNI) and the life expectancy at birth. Twenty countries participed in the surveys, covering 99% of the Latin American. The prevalence of end stage renal disease (ESRD) under RRT in Latin America (LA) increased from 119 patients per million population (pmp) in 1991 to 660 pmp in 2010 (HD 413 pmp, PD 135 pmp and LFG 111 pmp). HD proportionally increased more than PD, and Tx HD continues to be the treatment of choice in the region (75%). The kidney Tx rate increased from 3.7 pmp in 1987 to 6.9 pmp in 1991 and to 19.1 in 2010. The total number of Tx's in 2010 was 10 397, with 58% deceased donors. The total RRT prevalence correlated positively with GNI ( r 2 0.86; P chronic kidney disease (CKD) and its associated risk factors. PD is still an underutilized strategy for RRT in the region. Even though renal Tx is feasible, its growth rate is still not as fast as it should be in order to compensate for the increased prevalence of patients on waiting lists. Diagnostic and prevention programs for hypertension and diabetes, appropriate policies promoting the expansion of PD and organ procurement as well as transplantation as cost-effective forms of RRT are needed in the region. Regional cooperation among Latin American countries, allowing the more developed to

The present study was carried out to investigate the relative interaction between insulin, leptin and vitamin C in male patients with chronic renal failure and undergo regular haemodialysis (3 times/week). The study was carried out on 20 healthy volunteers as control (group I) and 20 with chronic renal failure (group II) which were studied before dialysis (A) and after dialysis (B). The serum results showed significant increases in creatinine, insulin and leptin levels in patient groups as compared to the control. On the other hand, significant decreases in the levels of glucose and vitamin C were recorded

The current guidelines for 2-deoxy-2-[18F]fluoro-d-glucose PET/CT scanning do not address potential inaccuracies that may arise due to patients with renal failure. We report a retrospective analysis of standard uptake values (SUVs) in patients with and without renal failure in order to warrant a protocol adjustment. Patients were matched based on age, gender, and BMI all of which are potential effectors on observed SUV. Thirty patients were selected with clinically diagnosed renal failure, of which 12 were on dialysis. All 30 patients had age, gender, and BMI control matches. Blood urea nitrogen and creatinine levels were measured within 1 month of the scan to assess renal failure. PET/CT scans for both the renal failure patients and controls were performed 60 min after FDG injection. SUVs were measured by placing circular regions of interest in the right hepatic lobe (LSUV) and left psoas muscle (PSUV). For the 30 renal failure patients, the mean LSUV was 2.77 (SD = 0.57) and PSUV was 1.43 (SD = 0.30) while the controls had mean LSUV 2.74 (SD = 0.50) and PSUV 1.42 (SD = 0.37). The SUVs from both the liver and psoas muscle were not significantly different between the renal failure patients and the normal controls with p values >0.05. In addition, dialysis and gender also had no effect on SUVs. Our data suggest that renal failure patients do not require an adjustment in protocol and the standard protocol times should remain.

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

The consequences of a supplemented very-low-protein diet remain a matter of debate with regard to patient outcome before or after the onset of renal replacement therapy. We evaluated the long-term clinical outcome during maintenance dialysis and/or transplantation in patients who previously received a supplemented very-low-protein diet. We assessed the outcome of 203 patients who received a supplemented very-low-protein diet for >3 mo (inclusion period: 1985-2000) and started dialysis after a mean diet duration of 33.1 mo (4-230 mo). The survival rate in the whole cohort was 79% and 63% at 5 and 10 y, respectively. One hundred two patients continued with chronic dialysis during the entire follow-up, and 101 patients were grafted at least once. Patient outcomes were similar to those of the French Dialysis Registry patients for the dialysis group and similar to the 865 patients who were transplanted in Bordeaux during the same period for the transplant group. There was no correlation between death rate and duration of diet. The lack of correlation between death rate and duration of diet and the moderate mortality rate observed during the first 10 y of renal replacement therapy confirm that a supplemented very-low-protein diet has no detrimental effect on the outcome of patients with chronic kidney disease who receive renal replacement therapy.

The chronic nephropathy is often present in pts with rheumatoid arthritis (RA). In the study the authors retrospectively analyzed the clinical course of the disease and outcomes of subsequent dialysotherapy in a group of pts with RA and end-stage renal disease ESRD. During last 5 years ESRD connected with RA was found in 10 (8 F, 2 M) pts out of 325 chronically dialyzed pts (peritoneal dialysis and hemodialysis) representing 3,1% of pts. The mean age at the initiation of dialysotherapy in these pts was 62,8 +/- 10,2 (range 46-76) years. Mean time from the diagnosis of RA to the start of dialysotherapy was 18,8 +/- 11,6 (range 5-40) years. Earlier the patients were treated with many disease modifying antirheumatic drugs (DMARDS) also with glucocorticosteroids and many nonsteroidal anti-inflammatory drugs. It means that they had rather aggressive type of RA. Amyloidosis was histological confirmed in 6 pts (4 F, 2 M). Peritoneal dialysis (PD) was the first choice therapy in 8 pts (2 on APD, 6 on CAPD). The main complication was increased incidence of peritonitis. 3 pts died on PD after 5, 9, 24 months (respectively) of CAPD treatment. 3 pts were transferred to HD after 5, 15, 18 (respectively) months of CAPD because of recurrent peritonitis. 2 pts up to date continue PD (one 12 months, the second 46 months on CAPD). In 5 pts who needed hemodialysis treatment there have been very serious problems with permanent vascular access formation. All used permanent indwelling catheters (Permcath). We concluded that: occurrence of ESRD in pts with RA was connected with aggressive type of disease. Pts with RA represent a dialysis group that is particularly prone to complications of PD (enteric peritonitis) and HD (vascular access problems). It seems to be connected with secondary vasculitis often found in pts with aggressive type of RA.
