End-Stage Renal Disease From Cast Nephropathy in a Teenager With Neuroendocrine Carcinoma.

PubMed

Butani, Lavjay; Ducore, Jonathan

2016-07-01

Cast nephropathy is the most common manifestation of renal injury in patients with multiple myeloma but is rarely reported in other conditions. We are reporting our experience in caring for a teenager with a metastatic neuroendocrine carcinoma who developed rapidly progressive kidney injury that advanced to end-stage renal disease. On renal biopsy extensive tubular necrosis and intratubular eosinophilic casts were noted. This previously unreported finding should prompt oncologists to closely monitor for such a complication in patients with secretory tumors. Whether early plasmapheresis could be of benefit, as has been tried in multiple myeloma, remains to be determined.

A 46-year old man with X-linked chronic granulomatous disease (CGD) being followed at the National Institute of Health with uncontrolled CGD colitis who developed chronic colovesical fistula, and end-stage renal disease (ESRD). Despite aggressive medical management of symptoms with immunomodulators and antibiotic prophylaxis, the chronic colovesical fistula led to chronic pyelonephritis, recurrent urinary tract infections, persistent air in the collecting system and bladder, and post-renal obstruction resulting in renal failure. Patient is now hemodialysis dependent and required diverting loop ileostomy placement. This report highlights multiple potential etiologies of rising serum creatinine in patients with CGD.

An exploration of the relationship between adherence with dietary sodium restrictions and health beliefs regarding these restrictions in Irish patients receiving haemodialysis for end-stage renal disease.

PubMed

2011-02-01

To measure adherence levels with dietary restrictions in Irish patients with end-stage renal disease receiving haemodialysis and to explore the relationships between adherence with dietary sodium restrictions and health beliefs in relation to following these restrictions in this group. Non-adherence to medical regimes is an important healthcare issue and an ever-present problem, particularly in patients with a chronic illness. The literature revealed a lack of studies measuring adherence with the sodium component of the renal dietary restrictions and associated factors; despite the fact that adherence with sodium restrictions is essential to the optimal management of end-stage renal disease. Furthermore, despite increased emphasis on 'the patients' view' in healthcare no study to date has contextualised health beliefs and adherence in end-stage renal disease from an Irish perspective. A quantitative, descriptive, correlational design was employed using the Health Belief Model as a theoretical framework. A convenience sample (n = 79) was recruited from the haemodialysis units of a large hospital. Data were collected using self-report questionnaires. Data were analysed using descriptive and correlational statistics. Non-adherence with dietary restrictions was a problem among a proportion of the sample. Greater adherence levels with dietary sodium restrictions were associated with greater 'perceived benefits' and fewer 'perceived barriers.' For the Irish patient, beliefs in relation to following a low sodium diet significantly affected adherence levels with this diet. This is an important finding as delineating key beliefs, particularly key barriers, facilitates an increased understanding of non-adherence for nurses. These findings have implications for the care of patients with end-stage renal disease in that they can provide guidance in terms of developing interventions designed to improve adherence. © 2011 Blackwell Publishing Ltd.

Integrating emotional and psychological support into the end-stage renal disease pathway: a protocol for mixed methods research to identify patients' lower-level support needs and how these can most effectively be addressed.

As a result of difficulties related to their illness, diagnosis and treatment, patients with end-stage renal disease experience significant emotional and psychological problems, which untreated can have considerable negative impact on their health and wellbeing. Despite evidence that patients desire improved support, management of their psychosocial problems, particularly at the lower-level, remains sub-optimal. There is limited understanding of the specific support that patients need and want, from whom, and when, and also a lack of data on what helps and hinders renal staff in identifying and responding to their patients' support needs, and how barriers to doing so might be overcome. Through this research we therefore seek to determine what, when, and how, support for patients with lower-level emotional and psychological problems should be integrated into the end-stage renal disease pathway. The research will involve two linked, multicentre studies, designed to identify and consider the perspectives of patients at five different stages of the end-stage renal disease pathway (Study 1), and renal staff working with them (Study 2). A convergent, parallel mixed methods design will be employed for both studies, with quantitative and qualitative data collected separately. For each study, the data sets will be analysed separately and the results then compared or combined using interpretive analysis. A further stage of synthesis will employ data-driven thematic analysis to identify: triangulation and frequency of themes across pathway stages; patterns and plausible explanations of effects. There is an important need for this research given the high frequency of lower-level distress experienced by end-stage renal disease patients and lack of progress to date in integrating support for their lower-level psychosocial needs into the care pathway. Use of a mixed methods design across the two studies will generate a holistic patient and healthcare professional perspective that is more likely to identify viable solutions to enable implementation of timely and integrated care. Based on the research outputs, appropriate support interventions will be developed, implemented and evaluated in a linked follow-on study.

End stage renal disease in French Guiana (data from R.E.I.N registry): South American or French?

End-Stage renal disease (ESRD) causes considerable morbidity and mortality, and significantly alters patients' quality of life. There are very few published data on this problem in the French Overseas territories. The development of a registry on end stage renal disease in French Guiana in 2011 allowed to describe the magnitude of this problem in the region for the first time. Using data from the French Renal Epidemiology and Information Network registry (R.E.I.N). Descriptive statistics on quantitative and qualitative variables in the registry were performed on prevalent cases and incident cases in 2011, 2012 and 2013. French Guiana has one of the highest ESRD prevalence and incidence in France. The two main causes of ESRD were hypertensive and diabetic nephropathies. The French Guianese population had a different demographic profile (younger, more women, more migrants) than in mainland France. Most patients had at least one comorbidity, predominantly (95.3%) hypertension. In French Guiana dialysis was initiated in emergency for 71.3% of patients versus 33% in France (p < 0.001). These first results give important public health information: i) End stage renal disease has a very high prevalence relative to mainland France ii) Patients have a different demographic profile and enter care late in the course of their renal disease. These data are closer to what is observed in the Caribbean or in Latin America than in Mainland France.

To evaluate the predictive value of the pediatric-modified Risk, Injury, Failure, Loss, End-stage renal disease criteria for disease course severity in patients with or without acute kidney injury admitted to a PICU. Retrospective cohort study. A 12-bed PICU at a tertiary referral center in Southern Brazil. All patients admitted to the study unit over a 1-year period. A database of all eligible patients was analyzed retrospectively. Patients were classified by pediatric-modified Risk, Injury, Failure, Loss, End-stage renal disease score at admission and worst pediatric-modified Risk, Injury, Failure, Loss, End-stage renal disease score during PICU hospitalization. The outcomes of interest were length of PICU stay, duration of mechanical ventilation, duration of vasoactive drug therapy, and mortality. The Pediatric Index of Mortality 2 was used to assess overall disease severity at the time of PICU admission. Of 375 patients, 169 (45%) presented acute kidney injury at the time of admission and 37 developed acute kidney injury during PICU stay, for a total of 206 of 375 patients (55%) diagnosed with acute kidney injury during the study period. The median Pediatric Index of Mortality 2 score predicted a mortality rate of 9% among non-acute kidney injury patients versus a mortality rate of 16% among acute kidney injury patients (p = 0.006). The mortality of patients classified as pediatric-modified Risk, Injury, Failure, Loss, End-stage renal disease F was double that predicted by Pediatric Index of Mortality 2 (7 vs 3.2). Patients classified as having severe acute kidney injury (pediatric-modified Risk, Injury, Failure, Loss, End-stage renal disease I + F) exhibited higher mortality (14.1%; p = 0.001) and prolonged PICU length of stay (median, 7 d; p = 0.001) when compared with other patients. Acute kidney injury is a very frequent occurrence among patients admitted to PICUs. The degree of acute kidney injury severity, as assessed by the pediatric-modified Risk, Injury, Failure, Loss, End-stage renal disease criteria, is a good predictor of morbidity and mortality in this population. Pediatric Index of Mortality 2 tends to underestimate mortality in pediatric patients with severe acute kidney injury.

Dialysis for end stage renal disease financed through the Brazilian National Health System, 2000 to 2012

PubMed Central

2014-01-01

Background Chronic kidney disease has become a public health problem worldwide. Its terminal stage requires renal replacement therapy – dialysis or transplantation – for the maintenance of life, resulting in high economic and social costs. Though the number of patients with end-stage renal disease treated by dialysis in Brazil is among the highest in the world, current estimates of incidence and prevalence are imprecise. Our aim is to describe incidence and prevalence trends and the epidemiologic profile of end-stage renal disease patients receiving publically-financed dialysis in Brazil between 2000 and 2012. Methods We internally linked records of the High Complexity Procedure Authorization/Renal Replacement Therapy (APAC/TRS) system so as to permit analyses of incidence and prevalence of dialysis over the period 2000-2012. We characterized temporal variations in the incidence and prevalence using Joinpoint regression. Results Over the period, 280,667 patients received publically-financed dialysis, 57.2% of these being male. The underlying disease causes listed were hypertension (20.8%), diabetes (12.0%) and glomerulonephritis (7.7%); for 42.3%, no specific cause was recorded. Hemodialysis was the therapeutic modality in 90.1%. Over this period, prevalence increased 47%, rising 3.6% (95% CI 3.2% - 4.0%)/year. Incidence increased 20%, or 1.8% (1.1% – 2.5%)/year. Incidence increased in both sexes, in all regions of the country and particularly in older age groups. Conclusions Incidence and prevalence of end-stage renal disease receiving publically-financed dialysis treatment has increased notably. The linkage approach developed will permit continuous future monitoring of these indicators. PMID:25008169

Pancreatitis with normal lipase and amylase level is a rare phenomenon. This is especially true in patient with end-stage renal disease as lipase and amylase are renally excreted. Literature review reveals previous case report of pancreatitis with normal lipase and amylase level, however, none of them occurred in the setting of end-stage renal disease. Our case is the first such reported case of pancreatitis in such setting. Here we report a 30year old male with past medical history of end-stage renal disease who presented in emergency department with acute abdominal pain. Laboratory work up revealed normal lipase and amylase level. However, radiological work up was consistent with pancreatitis. This case report highlight the importance of taking the overall clinical picture rather than laboratory work up to rule in or rule out the diagnosis of pancreatitis. Furthermore, this should also serve an important reminder for clinicians to further investigate where clinical suspicion for pancreatitis is high. Copyright © 2017 Elsevier Inc. All rights reserved.

Although many congenital diseases present disturbances of the central nervous system, eyes and renal function, only few of these have a defined genetic basis. The first clinical features of cerebro-oculo-renal diseases usually develop in early childhood and deterioration of kidney function and even end-stage kidney disease may occur in a young age. The syndromes should be considered in patients with retarded growth and development, central nervous system abnormalities, impaired vision or blindness and progressive renal failure.

The analysis of the scientific literature devoted to organ and tissue changes of oral cavity at the chronic renal insufficiency (CRI)is made. The number of patients in an end-stage of CRI constantly increases and patients receiving renal replacement therapy including hemodialysis, peritoneal dialysis or renal transplantation will comprise an enlarging segment of the dental patient population. Owing to CRI and its treatment there is a set of changes of teeth and oral cavity fabrics which remain even in a end-stage. Renal replacement therapy can affect periodontal tissues including gingival hyperplasia in immune suppressed renal transplantation patients and increased levels of bacterial contamination, gingival inflammation, formation of calculus, and possible increased prevalence and severity of destructive periodontal diseases. Besides, the presence of undiagnosed periodontitis may have significant effects on the medical management of the patients in end-stage of CRI.

Diabetes mellitus as a risk factor for incident chronic kidney disease and end-stage renal disease in women compared with men: a systematic review and meta-analysis.

Diabetes mellitus is a strong risk factor for chronic kidney disease and end-stage renal disease. Whether sex differences in chronic kidney disease and end-stage renal disease incidence exist among diabetic patients remains unclear. This systematic review and meta-analysis was conducted to evaluate the relative effect of diabetes on chronic kidney disease and end-stage renal disease risk in women compared with men. We systematically searched Embase, PubMed, and the Cochrane Library for both cohort and case-control studies until October 2015. Studies were selected if they reported a sex-specific relationship between diabetes mellitus and chronic kidney disease or end-stage renal disease. We generated pooled estimates across studies using random-effects meta-analysis after log transformation with inverse variance weighting. Ten studies with data from more than 5 million participants were included. The pooled adjusted risk ratio of chronic kidney disease associated with diabetes mellitus was 3.34 (95 % CI 2.27, 4.93) in women and 2.84 (95 % CI 1.73, 4.68) in men. The data showed no difference in diabetes-related chronic kidney disease risk between the sexes (pooled adjusted women-to-men relative risk ratio was 1.14 [95 % CI 0.97, 1.34]) except for end-stage renal disease-the pooled adjusted women-to men relative risk ratio was 1.38 (95 % CI 1.22, 1.55; p = 0.114, I² = 38.1 %). The study found no evidence of a sex difference in the association between diabetes mellitus and chronic kidney disease. However, the excess risk for end-stage renal disease was higher in women with diabetes than in men with the same condition, from which we assume that the female gender could accelerate the disease progression. Further studies are needed to support this notion and elucidate the underlying mechanisms.

The role of the renal specialist nurse in prevention of renal failure.

PubMed

Hurst, J

2002-01-01

This article will investigate the care required for those with reduced renal function before renal replacement therapy (RRT) commences. Renal nurses are often involved with the technical, monitoring and evaluative aspects of RRT for those with end stage renal failure. However, many patients may experience reduced renal function many years before reaching the stage of needing RRT. Renal nurses are already involved in the preparation of patients for RRT, but are not presently exercising their specialist skills in the period before this time by contributing to the prevention of end stage renal failure (ESRF). Screening programmes carried out in various parts of the world demonstrate that many members of the population have undetected renal insufficiency, and may benefit from intervention from the nephrology team to prevent further renal dysfunction. It is for this group of patients that this article will consider the potential for the renal nurse to expand their scope of practice.

To evaluate pro-inflammatory cytokines, homocysteinemia and markers of oxidative status in the course of chronic renal failure. One hundred and two patients (male/female: 38/64; age: 45±07 years) with chronic renal failure were divided into 4 groups according to the National Kidney Foundation classification. They included 28 primary stage renal failure patients, 28 moderate stage renal failure, 28 severe stage renal failure and 18 end stage renal failure. The inflammatory status was evaluated by the determination of pro-inflammatory cytokines (tumor necrosis factor-α, interleukin-1β, interleukin-6) and total homocysteine. Pro-oxidant status was assessed by assaying thiobarbituric acid reactive substances, hydroperoxides, and protein carbonyls. Antioxidant defence was performed by analysis of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase. Inflammatory markers were elevated in the end stage renal failure group compared to the other groups (P<0.001). Indeed, an increase in thiobarbituric acid reactive substances, hydroperoxides and protein carbonyls was noted in the end stage renal failure group in comparison with the other groups (P<0.001), while the levels of antioxidants enzymes activity were decreased in the study population (P<0.001). Impaired renal function is closely associated with the elevation of inflammatory markers leading to both increased markers of oxidative stress and decreased antioxidant defense.

DNA methylation and histone modifications determine renal programming and the development and progression of renal disease. The identification of the way in which the renal cell epigenome is altered by environmental modifiers driving the onset and progression of renal diseases has extended our understanding of the pathophysiology of kidney disease progression. In this review, we focus on current knowledge concerning the implications of epigenetic modifications during renal disease from early development to chronic kidney disease progression including renal fibrosis, diabetic nephropathy and the translational potential of identifying new biomarkers and treatments for the prevention and therapy of chronic kidney disease and end-stage kidney disease.

Lyons, Owen D; Inami, Toru; Perger, Elisa; Yadollahi, Azadeh; Chan, Christopher T; Bradley, T Douglas

2017-04-01

As in heart failure, obstructive and central sleep apnoea (OSA and CSA, respectively) are common in end-stage renal disease. Fluid overload characterises end-stage renal disease and heart failure, and in heart failure plays a role in the pathogenesis of OSA and CSA. We postulated that in end-stage renal disease patients, those with sleep apnoea would have greater fluid volume overload than those without.End-stage renal disease patients on thrice-weekly haemodialysis underwent overnight polysomnography on a nondialysis day to determine their apnoea-hypopnoea index (AHI). Extracellular fluid volume of the total body, neck, thorax and right leg were measured using bioelectrical impedance.28 patients had an AHI ≥15 (sleep apnoea group; OSA:CSA 21:7) and 12 had an AHI <15 (no sleep apnoea group). Total body extracellular fluid volume was 2.6 L greater in the sleep apnoea group than in the no sleep apnoea group (p=0.006). Neck, thorax, and leg fluid volumes were also greater in the sleep apnoea than the no sleep apnoea group (p<0.05), despite no difference in body mass index (p=0.165).These findings support a role for fluid overload in the pathogenesis of both OSA and CSA in end-stage renal disease.

1975-01-01

The nature of the original renal disease was determined in 403 consecutive cases of end-stage renal failure, in 317 of which the clinical diagnosis was corroborated by histological examination of the kidney. Five diseases accounted for 20 or more cases--glomerulonephritis (31% of the total), analgesic nephropathy (29%), primary vesicoureteral reflux (8%), essential hypertension (6%), and polycystic kidneys (5%). In only four cases did renal failure result from chronic pyelonephritis without a demonstrable primary cause. Greater use of micturating cystography and cystoscopy and routine urine testing for salicylate are advocated for earlier diagnosis of the major causes of "pyelonephritis". The incidence of end-stage renal failure in people aged 15-55 in New South Wales was estimated to be at least 34 new cases per million of total population each year. PMID:1090338

Early detection and prevention of diabetic nephropathy: a challenge calling for mandatory action for Mexico and the developing world.

PubMed

Correa-Rotter, Ricardo; González-Michaca, Luis

2005-09-01

During the last decades, developing countries have experienced an epidemiologic transition characterized by a reduction of infectious diseases and an increase of chronic degenerative diseases. This situation is generating tormenting public health, financial, and social consequences. Of particular relevance is type 2 diabetes mellitus and its chronic complications, particularly cardiovascular disease and diabetic nephropathy, because mortality of the patient with diabetes is, in most instances, related to these complications. There is a clear need to implement diagnostic and treatment strategies to reduce risk factors for development of diabetes (primary prevention), to detect risk factors of chronic complications in early stages of diabetes (secondary prevention), and to prevent further progression of those that already have renal injury (tertiary prevention). Microalbuminuria is an early marker of renal injury in diabetes, and its early detection can help the timely use of renal preventive measures, which would avoid the extremely high costs of renal replacement treatment for end-stage renal disease as well as that of other cardiovascular complications. Preventive strategies are of very little or no impact, if the primary physician has limited knowledge about the natural history of diabetic nephropathy, the beneficial effect of early preventive maneuvers for delaying its progression, and the social and economic impact of end-stage renal disease. It is therefore imperative to assure in our health systems that general practitioners have the ability and commitment to detect early diabetes complications, in order to promote actions that support regression or retard highly morbid cardiovascular and renal conditions.

Schievink, Bauke; Mol, Peter G M; Lambers Heerspink, Hiddo J

2015-11-01

There is increased interest in developing surrogate endpoints for clinical trials of chronic kidney disease progression, as the established clinically meaningful endpoint end-stage renal disease requires large and lengthy trials to assess drug efficacy. We describe recent developments in the search for novel surrogate endpoints. Declines in estimated glomerular filtration rate (eGFR) of 30% or 40% and albuminuria have been proposed as surrogates for end-stage renal disease. However, changes in eGFR or albuminuria may not be valid under all circumstances as drugs always have effects on multiple renal risk markers. Changes in each of these other 'off-target' risk markers can alter renal risk (either beneficially or adversely), and can thereby confound the relationship between surrogates that are based on single risk markers and renal outcome. Risk algorithms that integrate the short-term drug effects on multiple risk markers to predict drug effects on hard renal outcomes may therefore be more accurate. The validity of these risk algorithms is currently investigated. Given that drugs affect multiple renal risk markers, risk scores that integrate these effects are a promising alternative to using eGFR decline or albuminuria. Proper validation is required before these risk scores can be implemented.

2012-01-01

Primary hyperoxaluria type 1 (PH1) is characterized by progressive renal insufficiency culminating in end-stage renal disease, and a wide range of clinical features related to systemic oxalosis in different organs. It is caused by autosomal recessive deficiency of alanine:glyoxylate aminotransferase due to a defect in AGXT gene. Two brothers (one 6 months old; the other 2 years old) presented with acute renal failure and urinary tract infection respectively. PH1 was confirmed by high urinary oxalate level, demonstration of oxalate crystals in bone biopsy, and pathogenic homozygous known AGXT gene mutation. Despite the same genetic background, same sex, and shared environment, the outcome of the two siblings differs widely. While one of them died earlier with end-stage renal disease and multiorgan failure caused by systemic oxalosis, the older brother is pyridoxine responsive with normal development and renal function. Clinicians should be aware of extreme intrafamilial variability of PH1 and international registries are needed to characterize the genotype-phenotype correlation in such disorder.

Mitochondrial tRNAPhe mutation as a cause of end-stage renal disease in childhood

D’Aco, Kristin E; Manno, Megan; Clarke, Colleen; Ganesh, Jaya; Meyers, Kevin EC; Sondheimer, Neal

2012-01-01

Background We identified a mitochondrial tRNA mutation (m.586G>A) in a patient with renal failure and symptoms consistent with a mitochondrial cytopathy. This mutation was of unclear significance because there were neither consistent reports of linkage to specific disease phenotypes nor an existing analysis of effects upon mitochondrial function. Case-Diagnosis/Treatment A 16-month-old girl with failure-to-thrive, developmental regression, persistent lactic acidosis, hypotonia, GI dysmotility, adrenal insufficiency and hematologic abnormalities developed hypertension and renal impairment with chronic tubulointerstitial fibrosis, progressing to renal failure with need for peritoneal dialysis. Evaluation of her muscle and blood identified a mutation of the mitochondrial tRNA for phenylalanine, m.586G>A. Conclusions The m.586G>A mutation is pathogenic and is a cause of end-stage renal disease in childhood. The mutation interferes with the stability of tRNAPhe and affects the translation of mitochondrial proteins and the stability of the electron transport chain. PMID:23135609

Investigating the health profile of patients with end-stage renal failure receiving peritoneal dialysis: a cluster analysis.

To determine whether the patients with end stage renal failure can be differentiated into several subtypes based on five main variables. There is a lack of interventional research linking to clinical outcomes among the patients with end stage renal failure in Hong Kong and with no clear evidence of differences in terms of their clinical/health outcomes and characteristics. A cross-sectional survey. Data were collected using a structured questionnaire. One hundred and fifty-three patients with end stage renal failure were recruited during 2007 at three renal centres in Hong Kong. Five main variables were employed: predisposing characteristic, enabling resources, quality of life, symptom control and self-care adherence. A cluster analysis yielded two clusters. Each cluster represented a different profile of patients with end stage renal failure. Cluster A consisted of 49.7% (n = 76) and Cluster B consisted of 50.3% (n = 77) of the patients. Cluster A patients, more of whom were women, were older, less educated, had higher quality of life scores, a better adherence rate and more had received nursing care supports than patients in Cluster B. We have identified two groupings of patients with end stage renal failure who were experiencing unique health profile. Nursing support services may have an effect on patient health outcomes but only on a group of patients whose profile is similar to the patients in Cluster A and not for patients in Cluster B. A clear profile may help health care professional make appropriate strategies to target a specific group of patients to improve patient outcomes. The identification of risk for future health-care use could enable better targeting of interventional strategies in these groups. The results of this study might provide health care professionals with a model to design specified interventions to improve life quality for each profile group.

Peritoneal Dialysis in Asia.

PubMed

Kwong, Vickie Wai-Ki; Li, Philip Kam-Tao

2015-12-01

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. Lack of adequate education of practitioners and information of patients might as well be reasons for the low penetration of PD in both the East and West. (2) Patient survival of PD varies between and within countries but is globally similar to HD. (3) Peritonitis remains the main cause of morbidity in PD patients. South Asian countries face specific issues such as high tuberculosis and mycobacterial infections, which are rare in developed Asian and Western countries. The infection rate is affected by climatic and socio-economic factors and is higher in hot, humid and rural areas. (4) Nevertheless, the promotion of a PD-first policy might be beneficial particularly for remote populations in emerging countries where the end-stage renal disease rate is increasing dramatically.

Nephropathic cystinosis is an autosomal recessively inherited metabolic disorder presenting with metabolic acidosis, Fanconi syndrome and renal failure. We present a 6-year-old girl with severe growth failure, hyponatremia and hypokalemia. Her parents were 4(th) degree relatives. Two relatives were diagnosed as end stage renal failure. She also had persistant hypokalemic hypochloremic metabolic alkalosis. Her renal function was normal at presentation. She was thought to have Bartter syndrome with supporting findings of elevated levels of renin and aldosterone with normal blood pressure, and hyperplasia of juxtaglomerular apparatus. Her metabolic alkalosis did not resolve despite supportive treatment. At 6(th) month of follow-up proteinuria, glucosuria and deterioration of renal function developed. Diagnosis of cystinosis was made with slit lamp examination and leukocyte cystine levels. At 12(th) month of follow-up her metabolic alkalosis has converted to metabolic acidosis. In children presenting with persistant metabolic alkalosis, with family history of renal failure, and parental consanguinity, cystinosis should always be kept in mind as this disease is an important cause of end stage renal failure which may have features mimmicking Bartter syndrome.

Little is known about trace metal alterations in the bones of dialysis patients or whether particular types of renal osteodystrophy are associated with either increased or decreased skeletal concentrations of trace elements. Because these patients are at risk for alterations of trace elements as well as for morbidity from skeletal disorders, we measured trace elements in bone of patients with end-stage renal disease. We analyzed bone biopsies of 100 end-stage renal failure patients enrolled in a hemodialysis program. The trace metal contents of bone biopsies with histological features of either osteomalacia, adynamic bone disease, mixed lesion, normal histology, or hyperparathyroidism were compared with each other and with the trace metal contents of bone of subjects with normal renal function. Trace metals were measured by atomic absorption spectrometry. The concentrations of aluminum, chromium, and cadmium were increased in bone of end-stage renal failure patients. Comparing the trace metal/calcium ratio, significantly higher values were found for the bone chromium/calcium, aluminum/calcium, zinc/calcium, magnesium/calcium, and strontium/calcium ratios. Among types of renal osteodystrophy, increased bone aluminum, lead, and strontium concentrations and strontium/calcium and aluminum/calcium ratios were found in dialysis patients with osteomalacia vs the other types of renal osteodystrophy considered as one group. Moreover, the concentrations of several trace elements in bone were significantly correlated with each other. Bone aluminum was correlated with the time on dialysis, whereas bone iron, aluminum, magnesium, and strontium tended to be associated with patient age. Bone trace metal concentrations did not depend on vitamin D intake nor on the patients' gender. The concentration of several trace elements in bone of end-stage renal failure patients is disturbed, and some of the trace metals under study might share pathways of absorption, distribution, and accumulation. The clinical significance of the increased/decreased concentrations of several trace elements other than aluminum in bone of dialysis patients deserves further investigation.

Long-Term Outcomes of Renal Transplant in Recipients With Lower Urinary Tract Dysfunction.

Lower urinary tract dysfunction can lead to chronic kidney disease, which, despite surgical intervention, will progress to end-stage renal disease, requiring dialysis. Urologic pathology may damage a transplanted kidney, limiting patient and graft survival. Although smaller studies have suggested that urinary tract dysfunction does not affect graft or patient survival, this is not universally accepted. Northern Ireland has historically had the highest incidence of neural tube defects in Europe, giving rich local experience in caring for patients with lower urinary tract dysfunction. Here, we analyzed outcomes of renal transplant recipients with lower urinary tract dysfunction versus control recipients. We identified 3 groups of kidney transplant recipients treated between 2001 and 2010; those in group 1 had end-stage renal disease due to lower urinary tract dysfunction with prior intervention (urologic surgery, long-term catheter, or intermittent self-catheterization), group 2 had end-stage renal disease secondary to lower urinary tract dysfunction without intervention, and group 3 had end-stage renal disease due to polycystic kidney disease (chosen as a relatively healthy control cohort without comorbid burden of other causes of end-stage renal disease such as diabetes). The primary outcome measured, graft survival, was death censored, with graft loss defined as requirement for renal replacement therapy or retransplant. Secondary outcomes included patient survival and graft function. In 150 study patients (16 patients in group 1, 64 in group 2, and 70 in group 3), 5-year death-censored graft survival was 93.75%, 90.6%, and 92.9%, respectively, with no significant differences in graft failure among groups (Cox proportional hazards model). Five-year patient survival was 100%, 100%, and 94.3%, respectively. Individuals with a history of lower urinary tract dysfunction had graft and patient survival rates similar to the control group. When appropriately treated, lower urinary tract dysfunction is not a barrier to successful renal transplant.

Idiopathic membranous nephropathy: outline and rationale of a treatment strategy.

PubMed

du Buf-Vereijken, Peggy W G; Branten, Amanda J W; Wetzels, Jack F M

2005-12-01

Idiopathic membranous nephropathy is a common cause of nephrotic syndrome. The treatment of patients with idiopathic membranous nephropathy is heavily debated. Based on literature data and our own experience, we propose a rational treatment strategy. Patients with renal insufficiency (serum creatinine level > 1.5 mg/dL [> 135 micromol/L]) are at greatest risk for the development of end-stage renal disease and should receive immunosuppressive therapy. In patients with normal renal function (serum creatinine level < 1.5 mg/dL [< 135 micromol/L]), risk for developing end-stage renal disease can be estimated by measuring urinary excretion of beta2-microglobulin or alpha1-microglobulin and immunoglobulin G. For low-risk patients, a wait-and-see policy is advised. High-risk patients likely benefit from immunosuppressive therapy. Currently, combinations of steroids with chlorambucil or cyclophosphamide are the best studied. We prefer cyclophosphamide in view of its fewer side effects. Cyclosporine may be an alternative option in patients with well-preserved renal function, although long-term data are lacking. Other immunosuppressive agents, such as mycophenolate mofetil or rituximab, currently are under study; however, data are insufficient to support their routine use.

End-Stage Renal Disease Models in the Americas: Optimizing Resources to Achieve Better Health Outcomes.

End-stage renal disease, the last and most severe stage of chronic kidney disease, represents a major and rising concern for countries in Latin America, driven in large part by aging populations and the near-epidemic rises in diabetes, obesity, and hypertension. This places a great clinical, economic, and social burden on the region's health systems. During the ISPOR 6th Latin America Conference held in Sao Paulo, Brazil, in September 2017, an educational forum debated on value-based decision making in the treatment of end-stage renal disease in Latin America. We summarize the current state and how to build strategies and implement actions to move to a more patient-centered, outcomes-based approach for renal care in the region, taken from the discussions in the conference and also from a literature review. Models of renal care used in Ontario (Canada), Colombia, and a Chilean hospital stress the importance of empowering and supporting patients and their families, allowing for a better coordination between primary care providers and specialists, providing financial incentives to health units, and establishing an entity that holds insurers and providers accountable for health outcomes and costs of treatment. The study uses the framework of value-based health care for the evaluation of different dialysis options-peritoneal dialysis, hemodialysis, home dialysis, and so forth-and calls for the countries to adopt an integrated care model. We emphasize that countries in Latin America need to recognize the chronic kidney disease challenge and develop health systems and efficient renal care models to be able to reduce the burden of the disease.

Renal denervation represents an emerging treatment for resistant hypertension in patients with end-stage renal disease, but data about the anatomic substrate of this treatment are lacking. Therefore, the aim of this study was to investigate the morphological basis of sympathetic hyperactivity in the setting of hemodialysis patients to identify an anatomical substrate that could warrant the use of this new therapeutic approach. The distribution of sympathetic nerves was evaluated in the adventitia of 38 renal arteries that were collected at autopsy or during surgery from 25 patients: 9 with end-stage renal disease on dialysis (DIAL group) and 16 age-matched control nondialysis patients (CTRL group). Patients in the DIAL group showed a significant increase in nerve density in the internal area of the peri-adventitial tissue (within the first 0.5 mm of the beginning of the adventitia) compared with the CTRL group (4.01±0.30 versus 2.87±0.28×mm(2), P=0.01). Regardless of dialysis, hypertensive patients with signs of severe arteriolar damage had a greater number of nerve endings in the most internal adventitia, and this number was significantly higher than in patients without hypertensive arteriolar damage (3.90±0.36 versus 2.87±0.41×mm(2), P=0.04), showing a correlation with hypertensive arteriolar damage rather than with hypertensive clinical history. The findings from this study provide a morphological basis underlying sympathetic hyperactivity in patients with end-stage renal disease and might offer useful information to improve the use of renal denervation in this group of patients. © 2015 The Authors.

Consideration of Rat Chronic Progressive Nephropathy in Regulatory Evaluations for Carcinogenicity

PubMed Central

Hard, Gordon C.

2013-01-01

Chronic progressive nephropathy (CPN) is a spontaneous renal disease of rats which can be a serious confounder in toxicology studies. It is a progressive disease with known physiological factors that modify disease progression, such as high dietary protein. The weight of evidence supports an absence of a renal counterpart in humans. There is extensive evidence that advanced CPN, particularly end-stage kidney, is a risk factor for development of a background incidence of atypical tubule hyperplasia and renal tubule tumors (RTT). The likely cause underlying this association with tubule neoplasia is the long-term increased tubule cell proliferation that occurs throughout CPN progression. As a variety of chemicals are able to exacerbate CPN, there is a potential for those exacerbating the severity up to and including end-stage kidney to cause a marginal increase in RTT and their precursor lesions. Extensive statistical analysis of National Toxicology Program studies shows a strong correlation between high-grade CPN, especially end-stage CPN, and renal tumor development. CPN as a mode of action (MOA) for rat RTT has received attention from regulatory authorities only recently. In the absence of toxic effects elsewhere, this does not constitute a carcinogenic effect of the chemical but can be addressed through a proposed MOA approach for regulatory purposes to reach a decision that RTT, developing as a result of CPN exacerbation in rats, have no relevance for human risk assessment. Guidelines are proposed for evaluation of exacerbation of CPN and RTT as a valid MOA for a given chemical. PMID:23104430

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

Seeman, Tomáš; Hradský, Ondřej; Gilík, Jiří

2016-08-01

The aim of our study was to investigate whether nocturnal blood pressure (BP) dip is associated with increased left ventricular mass index and hypertrophy in children with hypertension (HT). We retrospectively reviewed data from all children with confirmed ambulatory HT in our center and performed ambulatory blood pressure monitoring (ABPM) and echocardiography at the same time. Left ventricular hypertrophy (LVH) was defined as left ventricular mass index (LVMI) ≥95th centile. Non-dipping phenomenon was defined as nocturnal BP dip <10 %. A total of 114 ABPM studies were included, the median age of children was 15.3 years (3.8-18.9), 80 children had renoparenchymal HT without end-stage renal failure, 34 had primary HT, and 27 studies were done on untreated children and 87 on treated children. Non-dipping phenomenon was present in 63 (55 %) studies (non-dippers). The LVMI adjusted for age was not significantly different between non-dippers and dippers (0.87 ± 0.03 vs. 0.81 ± 0.02, p = 0.13). Left ventricular hypertrophy was not significantly higher in non-dippers than in dippers (20 vs. 9 %, p = 0.12). Hypertensive children without end-stage renal failure with non-dipping phenomenon do not have increased prevalence of LVH or higher LVMI adjusted for age than hypertensive children with preserved nocturnal BP dip. • Adult and pediatric hypertensive patients with end-stage renal failure have often nocturnal blood pressure non-dipping phenomenon. • Non-dipping phenomenon is in patients with end-stage renal failure associated with increased prevalence of left ventricular hypertrophy. What is New: • Pediatric hypertensive patients without end-stage renal failure with blood pressure non-dipping phenomenon do not have increased prevalence of left ventricular hypertrophy.

Impact of age at onset for children with renal failure on education and employment transitions.

PubMed

Lewis, Helen; Arber, Sara

2015-01-01

Previous medical research has shown that children with end-stage renal failure experience delay or underachievement of key markers of transition to adulthood. This article analyses 35 qualitative interviews with end-stage renal failure patients, aged 20-30 years, first diagnosed at 0-19 years of age, to explore how far delayed or underachievement in education and employment is related to their age at onset of end-stage renal failure. This study shows how unpredictable failures of renal replacement therapies, comorbidities and/or side effects of treatment in the early life course often coincided with critical moments for education and employment. Entering school, college, work-related training or employment, and disclosing health status or educational underachievement to an employer, were particularly critical, and those who were ill before puberty became progressively more disadvantaged in terms of successful transition into full-time employment, compared with those first diagnosed after puberty. © The Author(s) 2014.

The purpose of this study is to provide insight into the relationship between dietary and fluid non-adherence, depressive symptoms, quality of life, perceived barriers and benefits of exercise, and perceived social support among Jordanian patients with end-stage renal disease receiving haemodialysis using Pender's health promotion model. Non-adherence to dietary and fluid restrictions is a leading cause of treatment failure and poor outcomes in end-stage renal disease. Yet, factors that interfere with the patients' ability to follow their dietary restrictions are unknown. A descriptive, correlational, cross-sectional design was used. Jordanian patients (n = 190) with end-stage renal disease receiving haemodialysis from three main Jordanian cities were included. The dialysis diet and fluid nonadherence questionnaire, Beck Depression Inventory-II, Quality Of Life Index, Dialysis Patient-Perceived Exercise Benefits and Barriers Scale, and the Multidimensional Perceived Social Support were employed to measure the key variables. Patients were more likely men with mean age of 48·2 ± 14·9. Only 27% of the patients showed full commitment to diet guidelines and 23% to fluid guidelines during the last 14 days. Depression (M = 18·8 ± 11·4) had significant negative association with quality of life (importance and satisfaction) (r = -0·60, r = -0·32, p = 0·001, respectively). Multiple hierarchal regressions revealed a predictive model of only two variables: age (B = -0·22, p = 0·05) and residual renal function (B = -0·23, p = 0·012) for dietary non-adherence. Non-adherence to diet and fluid guidelines association with individual characteristics, health perception and psychosocial variables should be investigated in a longitudinal design. Relationship of non-adherence with culture-related factors should deeply be assessed among Jordanian patients with end-stage renal disease receiving haemodialysis. Identification of the factors that may worsen dietary and fluid non-adherence may lead to improved therapeutic interventions within the mainstream of medical practice for Jordanian patients with end-stage renal disease receiving haemodialysis. © 2012 Blackwell Publishing Ltd.

Extreme intrafamilial variability of Saudi brothers with primary hyperoxaluria type 1

Alfadhel, Majid; Alhasan, Khalid A; Alotaibi, Mohammed; Al Fakeeh, Khalid

2012-01-01

Background Primary hyperoxaluria type 1 (PH1) is characterized by progressive renal insufficiency culminating in end-stage renal disease, and a wide range of clinical features related to systemic oxalosis in different organs. It is caused by autosomal recessive deficiency of alanine:glyoxylate aminotransferase due to a defect in AGXT gene. Case report Two brothers (one 6 months old; the other 2 years old) presented with acute renal failure and urinary tract infection respectively. PH1 was confirmed by high urinary oxalate level, demonstration of oxalate crystals in bone biopsy, and pathogenic homozygous known AGXT gene mutation. Despite the same genetic background, same sex, and shared environment, the outcome of the two siblings differs widely. While one of them died earlier with end-stage renal disease and multiorgan failure caused by systemic oxalosis, the older brother is pyridoxine responsive with normal development and renal function. Conclusion Clinicians should be aware of extreme intrafamilial variability of PH1 and international registries are needed to characterize the genotype-phenotype correlation in such disorder.

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.

Renal redox stress and remodeling in metabolic syndrome, type 2 diabetes mellitus, and diabetic nephropathy: paying homage to the podocyte.

Type 2 diabetes mellitus has reached epidemic proportions and diabetic nephropathy is the leading cause of end-stage renal disease. The metabolic syndrome constitutes a milieu conducive to tissue redox stress. This loss of redox homeostasis contributes to renal remodeling and parallels the concurrent increased vascular redox stress associated with the cardiometabolic syndrome. The multiple metabolic toxicities, redox stress and endothelial dysfunction combine to weave the complicated mosaic fabric of diabetic glomerulosclerosis and diabetic nephropathy. A better understanding may provide both the clinician and researcher tools to unravel this complicated disease process. Cellular remodeling of podocyte foot processes in the Ren-2 transgenic rat model of tissue angiotensin II overexpression (TG(mREN-2)27) and the Zucker diabetic fatty model of type 2 diabetes mellitus have been observed in preliminary studies. Importantly, angiotensin II receptor blockers have been shown to abrogate these ultrastructural changes in the foot processes of the podocyte in preliminary studies. An integrated, global risk reduction, approach in therapy addressing the multiple metabolic abnormalities combined with attempts to reach therapeutic goals at an earlier stage could have a profound effect on the development and progressive nature to end-stage renal disease and ultimately renal replacement therapy.

Background Nephropathic cystinosis is an autosomal recessively inherited metabolic disorder presenting with metabolic acidosis, Fanconi syndrome and renal failure. Case Presentation We present a 6-year-old girl with severe growth failure, hyponatremia and hypokalemia. Her parents were 4th degree relatives. Two relatives were diagnosed as end stage renal failure. She also had persistant hypokalemic hypochloremic metabolic alkalosis. Her renal function was normal at presentation. She was thought to have Bartter syndrome with supporting findings of elevated levels of renin and aldosterone with normal blood pressure, and hyperplasia of juxtaglomerular apparatus. Her metabolic alkalosis did not resolve despite supportive treatment. At 6th month of follow-up proteinuria, glucosuria and deterioration of renal function developed. Diagnosis of cystinosis was made with slit lamp examination and leukocyte cystine levels. At 12th month of follow-up her metabolic alkalosis has converted to metabolic acidosis. Conclusion In children presenting with persistant metabolic alkalosis, with family history of renal failure, and parental consanguinity, cystinosis should always be kept in mind as this disease is an important cause of end stage renal failure which may have features mimmicking Bartter syndrome.

Febuxostat, a nonpurine xanthine oxidase inhibitor, is approved as the first-line urate-lowering therapy in gout patients with normal renal function or mild to moderate renal impairment. The most common adverse effects of febuxostat are liver function test abnormalities, diarrhea, and skin rash. However, there is insufficient data in patients with severe renal impairment and end-stage renal disease (ESRD). We report the first case, to our knowledge, in which agranulocytosis developed after febuxostat treatment in an ESRD patient. A 67-year-old woman with gout and ESRD received febuxostat 40 mg a day for 2.5 months. She subsequently complicated with febrile neutropenia and the absolute neutrophil count was only 14/μL. After broad-spectrum antibiotics treatment and no more exposure to febuxostat for 17 days, her infection and neutrophil count recovered. Bone marrow study during neutropenic period showed myeloid hypoplasia without evidence of hematologic neoplasms. As febuxostat use may become more common in the population of advanced renal failure, clinicians should be aware of this rare but potentially life-threatening adverse effect. Based on our experience, close monitoring hemogram and immediate discontinuation of this medication may prevent serious consequences.

Renal transplantation is currently the only definitive treatment for end-stage renal disease; however, this treatment is severely limited by the shortage of implantable kidneys. To address this shortcoming, development of an engineered, transplantable kidney has been proposed. Although current advances in engineering kidneys based on decellularization and recellularization techniques have offered great promises for the generation of functional kidney constructs, most studies have been conducted using rodent kidney constructs and short-term in-vivo evaluation. Toward clinical translations of this technique, several limitations need to be addressed. Human-sized renal scaffolds are desirable for clinical application, and the fabrication is currently feasible using native porcine and discarded human kidneys. Current progress in stem cell biology and cell culture methods have demonstrated feasibility of the use of embryonic stem cells, induced pluripotent stem cells, and primary renal cells as clinically relevant cell sources for the recellularization of renal scaffolds. Finally, approaches to long-term implantation of engineered kidneys are under investigation using antithrombogenic strategies such as functional reendothelialization of acellular kidney matrices. In the field of bioengineering, whole kidneys have taken a number of important initial steps toward clinical translations, but many challenges must be addressed to achieve a successful treatment for the patient with end-stage renal disease.

Approximately 14% of Americans are living with chronic kidney disease (CKD). The prevalence of end-stage renal disease (ESRD), the result of progressing CKD continues to rise by 21,000 per year. There are no updated, evidence-based antibiotic prophylaxis guidelines for patients with renal disease undergoing dental treatment. The most recent was a scientific statement from the American Heart Association (AHA) in 2003. Presented in three parts, the goal of the first part of this study is to determine the current protocol being used to treat renal patients at U.S. dental schools. A 21 multiple-choice question survey was e-mailed to 58 clinic deans of accredited dental schools in the United States regarding renal treatment protocol details including antibiotic prophylaxis. Fifty-two percent of programs report having no established renal patient treatment protocol. For programs with a protocol, when using prophylactic antibiotics, 54% followed AHA protocol, whereas 62% used a modified protocol. There is a lack of consistent, established protocols among undergraduate dental programs. It is suggested that evidence-based guidelines for the safe treatment of patients be developed. © 2016 Special Care Dentistry Association and Wiley Periodicals, Inc.

Sudden cardiac death occurs commonly in the end-stage renal disease population receiving dialysis, with 25% dying of sudden cardiac death over 5 years. Despite this high risk, surprisingly few prospective studies have studied clinical- and dialysis-related risk factors for sudden cardiac death and arrhythmic precursors of sudden cardiac death in end-stage renal disease. We present a brief summary of the risk factors for arrhythmias and sudden cardiac death in persons with end-stage renal disease as the rationale for the Predictors of Arrhythmic and Cardiovascular Risk in End Stage Renal Disease (PACE) study, a prospective cohort study of patients recently initiated on chronic hemodialysis, with the overall goal to understand arrhythmic and sudden cardiac death risk. Participants were screened for eligibility and excluded if they already had a pacemaker or an automatic implantable cardioverter defibrillator. We describe the study aims, design, and data collection of 574 incident hemodialysis participants from the Baltimore region in Maryland, U.S.A.. Participants were recruited from 27 hemodialysis units and underwent detailed clinical, dialysis and cardiovascular evaluation at baseline and follow-up. Cardiovascular phenotyping was conducted on nondialysis days with signal averaged electrocardiogram, echocardiogram, pulse wave velocity, ankle, brachial index, and cardiac computed tomography and angiography conducted at baseline. Participants were followed annually with study visits including electrocardiogram, pulse wave velocity, and ankle brachial index up to 4 years. A biorepository of serum, plasma, DNA, RNA, and nails were collected to study genetic and serologic factors associated with disease. Studies of modifiable risk factors for sudden cardiac death will help set the stage for clinical trials to test therapies to prevent sudden cardiac death in this high-risk population.

Exploring the pathways leading from disadvantage to end-stage renal disease for indigenous Australians.

Indigenous Australians are disadvantaged, relative to other Australians, over a range of socio-economic and health measures. The age- and sex-adjusted incidence of end-stage renal disease (ESRD)--the irreversible preterminal phase of chronic renal failure--is almost nine times higher amongst Indigenous than it is amongst non-indigenous Australians. A striking gradient exists from urban to remote regions, where the standardised ESRD incidence is from 20 to more than 30 times the national incidence. We discuss the profound impact of renal disease on Indigenous Australians and their communities. We explore the linkages between disadvantage, often accompanied by geographic isolation, and both the initiation of renal disease, and its progression to ESRD. Purported explanations for the excess burden of renal disease in indigenous populations can be categorised as: primary renal disease explanations;genetic explanations;early development explanations; and socio-economic explanations. We discuss the strengths and weaknesses of these explanations and suggest a new hypothesis which integrates the existing evidence. We use this hypothesis to illuminate the pathways between disadvantage and the human biological processes which culminate in ESRD, and to propose prevention strategies across the life-course of Indigenous Australians to reduce their ESRD risk. Our hypothesis is likely to be relevant to an understanding of patterns of renal disease in other high-risk populations, particularly indigenous people in the developed world and people in developing countries. Furthermore, analogous pathways might be relevant to other chronic diseases, such as diabetes and cardiovascular disease. If we are able to confirm the various pathways from disadvantage to human biology, we will be better placed to advocate evidence-based interventions, both within and beyond the scope of the health-care system, to address the excess burden of renal and other chronic diseases among affected populations.

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 about prognosis and end-of-life care with end-stage renal disease patients. We anticipate that the intervention will help guide hemodialysis staff and providers to effectively participate in advance care planning for patients and caretakers to establish preferences and goals at the end of life.

2015-01-01

Liver transplantation (LT) is the standard of care for patients with decompensated cirrhosis. LT recipients have excellent short-term and long-term outcomes including patient and graft survival. Since the adoption of model for end-stage liver disease (MELD) - based allocation policy, the incidence of post-transplant end stage renal disease has risen significantly. Occurrence of stage 4 chronic kidney disease and end stage renal disease substantially increase the risk of post-transplant deaths. Since majority of late post-transplant mortality is due to non-hepatic post-transplant comorbidities, personalized care directed towards risk factor modification may further improve post-transplant survival.

Increased oxidative stress, elevated plasma homocysteine concentration, increased pulse pressure, and impaired endothelial function constitute risk factors for increased mortality in patients with end-stage renal failure. We investigated the metabolic and hemodynamic effects of intravenous administration of acetylcysteine, a thiol-containing antioxidant, during a hemodialysis session in a prospective, randomized, placebo-controlled crossover study in 20 patients with end-stage renal failure. Under control conditions, a hemodialysis session reduced plasma homocysteine concentration to 58+/-22% predialysis (mean+/-SD), whereas in the presence of acetylcysteine, the plasma homocysteine concentration was significantly more reduced to 12+/-7% predialysis (P<0.01). The reduction of plasma homocysteine concentration was significantly correlated with a reduction of pulse pressure. A 10% decrease in plasma homocysteine concentration was associated with a decrease of pulse pressure by 2.5 mm Hg. Analysis of the second derivative of photoplethysmogram waveform showed changes of arterial wave reflectance during hemodialysis in the presence of acetylcysteine, indicating improved endothelial function. Acetylcysteine-dependent increase of homocysteine removal during a hemodialysis session improves plasma homocysteine concentration, pulse pressure, and endothelial function in patients with end-stage renal failure.

OBJECTIVE To observe patient care across hemodialysis facilities enrolled in the National Opportunity to Improve Infection Control in ESRD (end-stage renal disease) (NOTICE) project in order to evaluate adherence to evidence-based practices aimed at prevention of infection. SETTING AND PARTICIPANTS Thirty-four hemodialysis facilities were randomly selected from among 772 facilities in 4 end-stage renal disease participating networks. Facility selection was stratified on dialysis organization affiliation, size, socioeconomic status, and urban/rural status. MEASUREMENTS Trained infection control evaluators used an infection control worksheet to observe 73 distinct infection control practices at the hemodialysis facilities, from October 1, 2011, through January 31, 2012. RESULTS There was considerable variation in infection control practices across enrolled facilities. Overall adherence to recommended practices was 68% (range, 45%-92%) across all facilities. Overall adherence to expected hand hygiene practice was 72% (range, 10%-100%). Compliance to hand hygiene before and after procedures was high; however, during procedures hand hygiene compliance averaged 58%. Use of chlorhexidine as the specific agent for exit site care was 19% overall but varied from 0% to 35% by facility type. The 8 checklists varied in the frequency of perfect performance from 0% for meeting every item on the checklist for disinfection practices to 22% on the arteriovenous access practices at initiation. CONCLUSIONS Our findings suggest that there are many areas for improvement in hand hygiene and other infection prevention practices in end-stage renal disease. These NOTICE project findings will help inform the development of a larger quality improvement initiative at dialysis facilities.

The epidemiology of end-stage renal disease in Nigeria: the way forward.

Odubanjo, M O; Oluwasola, A O; Kadiri, S

2011-09-01

The incidence of CKD (Chronic kidney disease) in Nigeria has been shown by various studies to range between 1.6 and 12.4%. We have shown that the burden of renal disease in Nigeria is probably significantly higher than any previous study on end-stage renal disease (ESRD) has documented, as most studies are hospital-based and fail to include the many patients who do not have access to hospital care. The increased prevalence of ESRD among blacks in the United States and South Africa compared with other races also suggests that ESRD may be more prevalent in Africa than in the United States and other developed nations. Common causes of CKD in Nigerian adults are glomerulonephritis and hypertension, while common causes in children are glomerulonephritis and posterior urethral valves. In the United States, diabetes and hypertension are the commonest causes of CKD and glomerulonephritis plays a less important role. Access to renal replacement therapy (RRT) in Nigeria is limited, and mortality rates are very high, ranging between 40 and 50%. Important steps towards improving the situation are the development of prevention programmes and increased funding to ensure increased availability of RRT. To achieve this, health policies concerning CKD must be formulated, and the lack of a renal registry makes it difficult for this to be done. There is need for the development of a functional organizational structure for the reporting of CKD in Nigeria, the Nigerian Renal Registry.

Preemptive Renal Transplantation-The Best Treatment Option for Terminal Chronic Renal Failure.

Renal transplantation is the best therapeutic option for end-stage chronic renal disease. Assuming that it is more advisable if performed early, we aimed to show the clinical, social, and economic advantages in 70% of our patients who were dialyzed only for a short period. For this purpose, we retrospectively collected data over 28 years in 142 kidney transplants performed in patients with <6 weeks on dialysis. 66% of our patients were 30-60 years old; 98% of the patients had living donors. At transplantation, 64% of our patients had no public support; however, 64% of them returned to work and got health insurance 2 months later. Full rehabilitation was achieved in all cases, including integration to the family, return to full-time work, school and university, sports, and reproduction. Immunosuppression consisted of 3 drugs, including steroids, cyclosporine, and azathioprine or mycophenolate. The cost in the 1st year, including patient and donor evaluation, surgery, immunosuppression, and follow-up, was $13,300 USD versus $22,320 for hemodialysis. We conclude that preemptive renal transplantation with <6 weeks on dialysis is the best therapeutic option for end-stage renal failure, especially in developing countries such as Bolivia, where until last year, full public support for renal replacement therapy was unavailable.

We aimed to investigate the epidemiology, risk factors, and short- and medium-term outcome of acute kidney injury classified according to pediatric Risk, Injury, Failure, Loss, End-Stage Renal Disease, and Kidney Disease: Improving Global Outcomes criteria in critically ill children. Prospective observational cohort study. Two eight-bed PICUs of a tertiary-care university hospital. A heterogeneous population of critically ill children. None. Demographic, clinical, laboratory, and outcome data were collected on all patients admitted to the PICUs from August 2011 to January 2012, with at least 24 hours of PICU stay. Of the 214 consecutive admissions, 160 were analyzed. The prevalence of acute kidney injury according to pediatric Risk, Injury, Failure, Loss, End-Stage Renal Disease and Kidney Disease: Improving Global Outcomes criteria was 49.4% vs. 46.2%, respectively. A larger proportion of acute kidney injury episodes was categorized as Kidney Disease: Improving Global Outcomes stage 3 (50%) compared with pediatric Risk, Injury, Failure, Loss, End-Stage Renal Disease F (39.2%). Inotropic score greater than 10 was a risk factor for acute kidney injury severity. About 35% of patients with acute kidney injury who survived were discharged from the PICU with an estimated creatinine clearance less than 75 mL/min/1.73 m and one persisted with altered renal function 6 months after PICU discharge. Age 12 months old or younger was a risk factor for estimated creatinine clearance less than 75 mL/min/1.73 m at PICU discharge. Acute kidney injury and its severity were associated with increased PICU length of stay and longer duration of mechanical ventilation. Eleven patients died; nine had acute kidney injury (p < 0.05). The only risk factor associated with death after multivariate adjustment was Pediatric Risk of Mortality score greater than or equal to 10. Acute kidney injury defined by both pediatric Risk, Injury, Failure, Loss, End-Stage Renal Disease and Kidney Disease: Improving Global Outcomes criteria was associated with increased morbidity and mortality, and may lead to long-term renal dysfunction.

ABSTRACT Hospitalists and primary care physicians encounter renal disease daily. Although most cases of acute kidney injury (AKI) are secondary to dehydration and resolve by giving fluids, many cases of AKI are due to not uncommon but unfamiliar causes needing nephrology evaluation. Common indications to consult a nephrologist on an emergency basis include hyperkalemia or volume overload in end stage renal disease patients (ESRD). Other causes of immediate consultation are cresenteric glomerulonephritis / rapidly progressive glomerulonephritis in which renal prognosis of the patient depends on timely intervention. The following evidence-based key information could improve patient care and outcomes. Abbreviations: AKI: Acute kidney injury ESRD: End stage renal disease patients PMID:28638567

To describe the clinical epidemiology of HIV-associated end-stage renal failure (HIV/ESRF) from 1998 to 2007 in the United Kingdom. Observational cohort study. Seven leading HIV centres and affiliated renal clinics in the United Kingdom. A total of 21 951 patients in whom renal function was measured. Development of end-stage renal failure (ESRF) as defined by initiation of permanent renal replacement therapy (pRRT). Sixty-eight (0.31%) patients had HIV/ESRF, 44 (64.7%) of whom were black. The prevalence of ESRF in black patients increased over time from 0.26% in 1998-1999 to 0.92% in 2006-2007 (P for trend = 0.001). Overall 5-year survival from starting pRRT was 70.3%, and significantly better for black patients compared to those of other ethnicities (85.2 vs. 43.4%, P = 0.001). In multivariable analysis, black ethnicity was associated with a higher risk of ESRF [HR 6.93, 95% confidence interval (CI) 3.56, 13.48], whereas a higher current CD4 cell count was associated with reduced risk (HR: 0.83, 95% CI 0.76, 0.95) per 50 cells higher). No association was seen between current viral load or current highly active antiretroviral therapy (HAART) status and ESRF. On the basis of these observations, we estimate that 231 HIV-infected patients required pRRT in the United Kingdom in 2007, and an HIV prevalence of 0.51% among the United Kingdom pRRT recipients in that year. The prevalence of HIV/ESRF increased during the HAART era to reach nearly 1% in black patients, in whom favourable survival rates were observed. Earlier HIV diagnosis will be an important strategy to stem the rising trend of HIV/ESRF.

Organ transplantation has prolonged and improved the lives of many patients around the world. However, a widespread shortage of donors remains the main factor that has led to organ trafficking and transplant tourism. To stop transplant tourism and to provide optimal treatment for its citizens with end-stage renal disease, Montenegro started performing renal transplantations in September 2012. Thirty-five transplantations have been performed since that time, 34 from living donors and only 1 from a deceased donor. This practice has significantly decreased but not ended transplant tourism in Montenegro. Copyright © 2018 Elsevier Inc. All rights reserved.

Immunoglobulin-G4 (IgG4)-related tubulo-interstitial nephritis (IgG4TIN) could be the first presentation of IgG4-related systemic disease. Most of the data is from the West or Japan and retrospective, with good patient outcome. This study was carried out from April 2011 to July 2013. We report a prospective follow-up of 11 patients who presented with renal dysfunction and had histological diagnosis of IgG4TIN followed for a minimum period of 1 year or until end-stage renal disease. IgG4TIN constituted 0.28% of total renal biopsies and 6.5% of all tubulointerstitial nephritis. Patient ages ranged between 21 and 71 years with a male predominance. All the patients had renal dysfunction at presentation with a mean serum creatinine of 5.12 mg/dL. Proteinuria was subnephrotic except when there was coexisting membranous glomerulonephritis (36.4%). The mean 24-h urine protien excretion was 1.8 g. Serum IgG4 levels were elevated in 10 (90.9%) patients. Ten (90.9%) patients had renomegaly and one (9.1%) had focal renal mass. Extra-renal manifestations were present in seven (63.6%). Renal histology showed pattern A in five (45.5%), pattern B in four (36.3%) and pattern C in two (18.1%) patients. All but one patient (90.9%) received immunosuppressive therapy. Four (36.3%) achieved complete remission and three (27.2%) progressed to end stage renal disease. Two patients died due to infections while on steroid therapy. One patient with a mass had end stage renal disease for 12 months and did not improve with steroid therapy, and one (pattern C) had progressive chronic kidney disease on follow-up.

End-stage renal disease (ESRD) is a serious health problem worldwide. The high prevalence of cardiovascular diseases and chronic inflammation remains a major cause of morbidity and mortality in haemodialysed patients. Beside some external factors, genetic predisposition both to renal failure and poor prognosis has been assumed. We have collected a total of 1,014 haemodialysed patients and 2,559 unrelated healthy Caucasians. Single-nucleotide polymorphisms (SNPs) in genes for preproghrelin (GHRL), lipopolysaccharide-binding protein (LBP), HFE and MTHFR were genotyped. In the group of patients, significantly more carriers presented the MTHFR T667T (P = 0.002) and HFE Asp63Asp (P = 0.001) and Cys282Cys (P = 0.01) genotypes. The frequencies of individual SNPs within GHRL and LBP genes did not differ between the patients and controls. The trends in genotype frequencies did not differ between the subgroups of patients with different time on haemodialysis. Common variants in MTHFR and HFE could be a risk factor for all-cause ESRD development, but are not predictors for the survival on haemodialysis.

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.

Adjustment of drug dosage in patients with end-stage renal disease prevents serious adverse effects, which occur due to the accumulation of drugs or other toxic metabolites. Nevertheless, dosing errors occur most commonly among patients with end-stage renal disease. The aim of this study was to assess the quality of care for end-stage renal disease outpatients using their renal dosing adjustment status. A cross-sectional study was performed using the data collected from 43 South Korean medical institutions via questionnaires. A total of 2428 patients on haemodialysis, who were at least 18 years of age, were included. Among these patients, the study population was confined to patients who were taking medications and required renal dosing adjustments from three therapeutic classes: antihypertensives, antihyperglycaemics and lipid-modifying agents. The study population (n = 828) was prescribed a total of 1097 drug orders for the target drugs. Determination of appropriate dosage adjustment was based on GFR (glomerular filtration rate) using the Modification of Diet in Renal Disease revised 4-variable equation. The primary outcome was non-adherence to drug dosing requirements for end-stage renal disease patients with consideration to their renal function. Among the study population (n = 828), 469 haemodialysis patients were identified as having drug orders that were adherent to renal dosing recommendations. There were significant differences between the patient groups who received recommendation-adherent and non-adherent drug orders in the characteristics of the medical institutions they visited, causes of chronic renal failure and prevalence of concurrent diabetes mellitus. The primary factor of non-adherence to renal dosing adjustment recommendations was characteristics of medical institutions. Compared to tertiary hospitals, secondary hospitals and primary care clinics were 1·16 and 1·22 times, respectively, more non-adherent in accordance with the multivariate analysis (OR: 1.16, 95% CI: 1.02-1.20, OR: 1.22, 95% CI: 1·00-1·36, respectively). Dosing error is one of the most common problems among patients with renal failure. To decrease the dosing errors, an improvement needs to be made in medical institutions. This can be accomplished by implementing the clinical decision support systems that educate physicians on appropriate renal dosing and help them prescribe appropriate drug dosages. © 2015 John Wiley & Sons Ltd.

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.

To evaluate the influence of different stages of chronic renal insufficiency on the pharmacokinetics and safety/tolerability of the transdermally applied dopamine agonist rotigotine in an open label group comparison including 32 subjects (healthy, mild, moderate or severe impairment of renal function and patients with end-stage renal insufficiency requiring haemodialysis). METHODS All subjects received a single transdermal 10 cm² patch (24 h patch-on period) containing 4.5 mg rotigotine (nominal drug release 2 mg 24 h⁻¹). Main evaluations included relative bioavailability and renal elimination of rotigotine and its metabolites. Point estimates for the ratios between the groups with moderate to severe renal impairment and healthy subjects for the pharmacokinetic parameters AUC(0,t(last) ) and C(max) for the active substance unconjugated rotigotine were near 1:0.88 for AUC and 0.93 for C(max) for moderate renal impairment, 1.14 and 1.18 for severe renal impairment and 1.05 and 1.25 for end-stage renal insufficiency requiring haemodialysis. There was no correlation of these parameters with creatinine clearance. The amount of unconjugated rotigotine excreted into urine and renal clearance decreased with increasing severity of renal insufficiency but had no observable effect on total clearance as the amounts excreted were below 1% of the administered dose. Occurrence of adverse events did not increase with the degree of renal insufficiency. The pharmacokinetic profiles of unconjugated rotigotine were similar in healthy subjects and subjects with impaired renal function indicating that no dose adjustments are required for transdermal rotigotine in patients with different stages of chronic renal insufficiency including patients on haemodialysis. © 2011 UCB Biosciences GmbH.

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

Adjustment to the lifestyle changes imposed by end-stage renal disease is particularly difficult when the onset is abrupt and unheralded. A case of atheroembolism is presented in which living situation, dietary compliance, and family involvement are particularly problematic for the dialysis staff. Discussion by team members focuses on the evolution of a reasonable disposition through diligence and persistence, recognizing the need to compromise medical indications with individual lifestyle and available family support.

Approximately 14% of Americans are living with chronic kidney disease (CKD). The prevalence of end-stage renal disease (ESRD), the result of progressing CKD continues to rise by 21,000 per year. Currently, the only antibiotic prophylaxis guidelines for patients with ESRD undergoing dental treatment were published by the AHA in 2003. Presented in three parts, the first and second parts of this study found no consistent protocols amongst U.S. dental schools and U.S. GPRs and AEGDs, respectively. The goal of the third part of the project was to determine the current protocol being used to treat ESRD patients at U.S. nephrology fellowship programs. An 18 multiple-choice question survey was e-mailed to 130 directors of nephrology fellowships within the U.S. regarding renal treatment protocol details and antibiotic prophylaxis for patients with renal disease. Note that, 34.6% of respondents reported having an established renal treatment protocol. For programs with a protocol, 69% of programs reported following AHA guidelines. There is a lack of consistent, established protocols amongst U.S. nephrology fellowships. It is suggested that updated and evidence based guidelines for the safe treatment of patients be developed. © 2016 Special Care Dentistry Association and Wiley Periodicals, Inc.

Patients after liver transplantation (LT) with hepatitis C virus (HCV) infection often suffer from renal or hepatic impairment. Treating patients after LT with direct-acting antivirals (DAA) might result in decreasing renal function due to interaction of DAA and immunosuppressive therapy. In this single-center study we analyzed clinical parameters of 18 HCV-infected patients treated with DAA therapy after LT. The primary end points were change of renal function (glomerular filtration rate) and sustained virologic response 12 weeks after therapy (SVR12). For secondary end points, we investigated the influence of DAA therapy on transaminases, bilirubin, international normalized ratio, noninvasive fibrosis measurement, and Model for End-Stage Liver Disease (MELD) score. Five out of 18 patients treated with DAA suffered from renal impairment stage 2, and 7 patients of renal impairment stage 3. Renal function at SVR12 was not influenced by preexisting renal impairment (P > .5), type of immunosuppressant (P > .5), or type of DAA regimen (P > .5). All patients reached SVR12. The levels of transaminases and bilirubin declined rapidly, as expected. Ten out of 18 patients already suffered from cirrhosis or liver fibrosis >F3 according to noninvasive measurement before initiation of treatment. Single-point acoustic radiation force impulse imaging improved in 9 patients (P = .012). In 7 patients, MELD score improved owing to the decrease of bilirubin levels. In 6 patients it worsened. DAA therapy in LT patients was effective and safe in this single-center real-life cohort. Renal function was not influenced by the administered drug combinations, even in patients with preexisting renal impairment. Copyright © 2018. Published by Elsevier Inc.

Hypothyroidism in patients with renal failure (RF) causes many metabolic and clinical problems, and both these diseases can mutually exacerbate their disturbances. The aim of this study was to evaluate the effect of hypothyroidism, and end-stage renal disease (ESRD) on conversion of thyroid hormones (TH) in patients with ESRD treated with chronic hemodialysis (HD). The study was performed in 74 patients, including 41 women (K) and 33 men (M) aged 28-83 y.o. in 4 groups: G1 - 12 people with ESRD treated with HD and with newly diagnosed hypothyroidism without substitution (6 K and M 6) aged 66,83±12,90 y.o., G2 - 26 patients with ESRD treated with HD without hypothyroidism (10 F, 16 M) aged 58,85±15,52 y.o., G3 - 11 hypothyroid patients without RF (9 K, 2 M) aged 54,73±21,26 y.o., G4 - 25-persons from control group of healthy subjects (16 M, 9 M) aged 51,24±12,58 y.o. In all subjects the concentration of TSH and TH (T4, T3, fT4, TSH, FT3, rT3) were measured and values of conversion factors (T3/T4, FT3/ fT4, rT3/fT4 and rT3/fT3) and binding TH to protein factors (fT4/T4 and fT3/T3) were calculated. Lower concentration of T3 (p=0.012), fT3 (p<0.001) i fT4 (p=0.014) was found in patients without hypothyroidism than in healthy subjects. Renal failure with concomitant hypothyroidism intensify the disturbances of T4 to T3 conversion (p=0.034) and hypothyroidism with concomitant renal failure disrupts binding of T3 to proteins (p=0.001). FT3 to fT4 ratio in renal failure with concomitant hypothyroidism group was significantly lower than in each other group. rT3 concentrations were the highest in healthy subjects. Concomitance of hypothyroidism and end-stage renal disease reduces the conversion of thyroxine to triiodothyronine, but does not increase the production of rT3. Hypothyroidism significantly increases the disorders of thyroid hormones in end-stage renal disease. There is decreased tendency to bind of thyroid hormone to protein in hypothyroidism in patients with end-stage renal disease.

Latin American Dialysis and Transplant Registry: Experience and contributions to end-stage renal disease epidemiology.

In 2015, 634387 million people (9% of the world's population) resided in Latin America (LA), with half of those populating Brazil and Mexico. The LA Dialysis and Transplant Registry was initiated in 1991, with the aim of collecting data on renal replacement therapy (RRT) from the 20 LA-affiliated countries. Since then, the Registry has revealed a trend of increasing prevalence and incidence of end-stage kidney disease on RRT, which is ongoing and is correlated with gross national income, life expectancy at birth, and percentage of population that is older than 65 years. In addition, the rate of kidney transplantation has increased yearly, with > 70% being performed from deceased donors. According to the numbers reported for 2013, the rates of prevalence, incidence and transplantation were (in patients per million population) 669, 149 and 19.4, respectively. Hemodialysis was the treatment of choice (90%), and 43% of the patients undergoing this treatment was located in Brazil; in contrast, peritoneal dialysis prevailed in Costa Rica, El Salvador and Guatemala. To date, the Registry remains the only source of RRT data available to healthcare authorities in many LA countries. It not only serves to promote knowledge regarding epidemiology of end-stage renal disease and the related RRT but also for training of nephrologists and renal researchers, to improve understanding and clinical application of dialysis and transplantation services. In LA, accessibility to RRT is still limited and it remains necessary to develop effective programs that will reduce risk factors, promote early diagnosis and treatment of chronic kidney disease, and strengthen transplantation programs.

To study prospectively the ethnic-specific risks of cardiovascular disease, end-stage renal disease and all-cause mortality in patients with Type 2 diabetes mellitus among native Asian subpopulations. A total of 2337 subjects with Type 2 diabetes (70% Chinese, 17% Malay and 13% Asian Indian) were followed for a median of 4.0 years. Time-to-event analysis was used to study the association of ethnicity with adverse outcomes. Age- and gender-adjusted hazard ratios for cardiovascular disease in ethnic Malay and Asian Indian subjects were 2.01 (1.40-2.88; P<0.0001) and 1.60 (1.07-2.41; P=0.022) as compared with Chinese subjects. Adjustment for conventional cardiovascular disease risk factors, including HbA1c , blood pressure and lipid profile, slightly attenuated the hazards in Malay (1.82, 1.23-2.71; P=0.003) and Asian Indian subjects (1.47, 0.95-2.30; P=0.086); However, further adjustment for baseline renal function (estimated GFR) and albuminuria weakened the cardiovascular disease risks in Malay (1.48, 0.98-2.26; P=0.065) but strengthened that in Asian Indian subjects (1.81, 1.14-2.87; P=0.012). Competing-risk regression showed that the age- and gender-adjusted sub-distribution hazard ratio for end-stage renal disease was 1.87 (1.27-2.73; P=0.001) in Malay and 0.39 (0.18-0.83; P=0.015) in Asian Indian subjects. Notably, the difference in end-stage renal disease risk among the three ethnic groups was abolished after further adjustment for baseline estimated GFR and albuminuria. There was no significant difference in risk of all-cause mortality among the three ethnic groups. Risks of cardiovascular and end-stage renal diseases in native Asian subjects with Type 2 diabetes vary substantially among different ethnic groups. Differences in prevalence of diabetic kidney disease may partially explain the ethnic disparities. © 2015 The Authors. Diabetic Medicine © 2015 Diabetes UK.

The dialysis outcomes quality initiative: history, impact, and prospects.

Rigorously developed clinical practice guidelines have the potential to improve patient outcomes. It is toward that end that the National Kidney Foundation (NKF) launched in March 1995 the Dialysis Outcome Quality Initiative (DOQI), an ambitious effort to develop evidence-based clinical practice guidelines for the care of patients with end-stage renal disease (ESRD). Independent, interdisciplinary work groups conducted a structured review of the content and methodologic rigor of all the published literature pertinent to four selected topics: hemodialysis adequacy, peritoneal dialysis adequacy, vascular access, and anemia. Following expert, organizational, and public review, the guidelines were issued in September and October 1997. An implementation plan that called for widespread dissemination of the guidelines and facilitation of adoption of them has resulted in their broad acceptance and Integration into quality improvement efforts. Additional guidelines on nutrition have recently been completed, while others on bone disease, hypertension, and hyperlipidemia are in various stages of planning or development. A major determinant of poor outcome of maintenance dialysis patients is the debilitated state of many individuals with ESRD at the time that they commence dialysis therapy. The recognition of this problem has stimulated an interest in extending the guidelines to management of patients with less severe renal insufficiency, well before they need renal replacement therapy; and to the early detection of renal insufficiency by a proteinuria and albuminuria risk assessment, detection, and elimination (PARADE) program. What started as an initiative to improve the quality of care of dialysis patients has evolved into a considerably expanded effort to making lives better for all individuals with any level of renal insufficiency.

Diabetic nephropathy. Is end-stage renal disease inevitable?

PubMed

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.

To determine the risk factors, clinical characteristics, surgical management and outcome of pseudoaneurysm secondary to iatrogenic or traumatic vascular injury. This was a cross-sectional study being performed in department of cardiovascular and thoracic surgery skims soura during a 4-year period. We included all the patients referring to our center with primary diagnosis of pseudoaneurysm. The pseudoaneurysm was diagnosed with angiography and color Doppler sonography. The clinical and demographic characteristics were recorded and the risk factors were identified accordingly. Patients with small swelling (less than 5-cm) and without any complication were managed conservatively. They were followed for progression and development of complications in relation to swelling. Others underwent surgical repair and excision. The outcome of the patients was also recorded. Overall we included 20 patients with pseudoaneurysm. The mean age of the patients was 42.1±0.6 years. Among them there were 11 (55%) men and 9 (45%) women. Nine (45%) patients with end stage renal disease developed pseudoaneurysm after inadvertent femoral artery puncture for hemodialysis; two patients after interventional cardiology procedure; one after femoral embolectomy; one developed after fire arm splinter injury and one formed femoral artery related pseudoaneurysm after drainage of right inguinal abscess. The most common site of pseudoaneurysm was femoral artery followed by brachial artery. Overall surgical intervention was performed in 17 (85%) patients and 3 (15%) were managed conservatively. End stage renal disease is a major risk factor for pseudoaneurysm formation. Coagulopathy, either therapeutic or pathological is also an important risk factor. Patients with these risk factors need cannulation of venous structures for hemodialysis under ultrasound guide to prevent inadvertent arterial injury. Patients with end stage renal disease who sustain inadvertent arterial puncture during cannulation for hemodialysis should receive compression dressings for 5 to 7 days.

Down syndrome is one of the most common genetic causes of learning disabilities in children. Although the incidence of renal and urological involvement in Down syndrome is not very common, monitoring of patients with Down syndrome for renal diseases should be done regularly as patient's age into the second and third decades. With increased survival, it appears that a growing number of these patients present with chronic renal failure. Down syndrome patients are apparently not suited for peritoneal dialysis because of lacking cooperation. This procedure can be prone to failure, mainly because of an increased risk of peritonitis. Handling such patients especially those on peritoneal dialysis is challenging. Here we report a case of Down syndrome with end-stage renal disease treated with hemodialysis for 6 months. To the best of our knowledge and current literature review this is the first case report of a patient with Down syndrome undergoing hemodialysis.

The drama of the continuous increase in end-stage renal failure in patients with type II diabetes mellitus.

Type II diabetes mellitus has become the leading cause of end-stage renal failure in many countries of Western Europe. In all European countries, even in those with a relatively low prevalence of diabetic nephropathy, the number of patients with type II diabetes mellitus admitted for renal replacement therapy has recently increased continuously. Survival and medical rehabilitation of patients with type II diabetes on renal replacement therapy is significantly worse than in non-diabetic patients. It is obvious that in order to stem the tide, intense efforts are necessary (i) to inform the medical community about the renal risk of type II diabetes and the striking effectiveness of preventive measures, (ii) to provide better care for diabetic patients, and (iii) to reduce the high prevalence of diabetes in the population by modification of the Western life style.

We report three cases of fatal pancreatitis associated with systemic AA amyloidosis in rheumatoid arthritis (RA). All of the patients showed end-stage renal failure, and hemodialysis was introduced during the course of treatment. Autopsy was performed on two of the three patients, and this revealed amyloid deposition on the vascular walls in the pancreas. It was strongly suggested that the acute pancreatitis in all three patients was attributable to deposition of amyloid in vascular and pancreatic tissues. Acute pancreatitis is considered to be a rare complication of end-stage amyloidosis associated with RA, and is frequently fatal. It is important to treat RA patients intensively to avoid such deposition of amyloid.

End-stage renal disease (ESRD) is an important cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). To analyze the outcome and prognostic factors of renal transplantation in patients with ESRD due to SLE from January 1986 to December 2013 in a single center. Fifty renal transplantations were performed in 40 SLE patients (32 female (80%), mean age at transplantation 36±10.4 years). The most frequent lupus nephropathy was type IV (72.2%). Graft failure occurred in a total of 15 (30%) transplantations and the causes of graft failure were chronic allograft nephropathy (n=12), acute rejection (n=2), and chronic humoral rejection (1). The death-censored graft survival rates were 93.9% at 1 year, 81.5% at 5 years, and 67.6% at the end of study. The presence of deceased donor allograft (P=0.007) and positive anti-HCV antibodies (P=0.001) negatively influence the survival of the renal transplant. The patient survival rate was 91.4% at the end of the study. Recurrence of lupus nephritis in renal allograft was observed in one patient. Renal transplantation is a good alternative for renal replacement therapy in patients with SLE. In our cohort, the presence of anti-HCV antibodies and the type of donor source were related to the development of graft failure.

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.

Lifestyle modification and progressive renal failure.

PubMed

Ritz, Eberhard; Schwenger, Vedat

2005-08-01

There is increasing evidence that lifestyle factors impact on the risk of developing chronic kidney disease (CKD) and the risk of progression of CKD. Equally important is the consideration that patients with CKD are more likely to die from cardiovascular disease than to reach the stage of end-stage renal failure. It is advantageous that manoeuvres that interfere with progression at the same time also reduce the risk of cardiovascular events. Lifestyle factors that aggravate progression include, among others, smoking, obesity and dietary salt intake. Alcohol consumption, according to some preliminary information, has a bimodal relationship to cardiovascular risk and progression, with moderate consumption being protective.

We report on a female patient with rheumatoid arthritis and end-stage renal-disease following AA-amyloidosis who presented with chest pain to the emergency department. ECG showed no signs of ischemia, echocardiography revealed a concentric left ventricular hypertrophy with increased texture. Serum concentration of troponin I was mildly elevated whereas creatine kinase (CK)/ CK-MB were normal. The chief complaints resolved spontaneously and there was no change in the serum troponin-I and CK/CK-MB concentrations. Coronary heart disease was ruled out by angiography and cardiac involvement of the underlying AA-amyloidosis was diagnosed. After one month, the patient suffered from a syncope complicated by a pelvic ring fracture with hemorrhagic shock and declined chronic dialysis treatment. Patients with end-stage renal disease may exhibit a persisting elevation of serum troponin concentration reflecting the high burden of cardiovascular disease. Myocardial infarction can be distinguished by the lack of increase in serial tests. Copyright Georg Thieme Verlag KG Stuttgart . New York.

This study aimed to evaluate the validity and reliability of the Persian version of Death Anxiety Scale-Extended (DAS-E). A total of 507 patients with end-stage renal disease completed the DAS-E. The factor structure of the scale was evaluated using exploratory factor analysis with an oblique rotation and confirmatory factor analysis. The content and construct validity of the DAS-E were assessed. Average variance extracted, maximum shared squared variance, and average shared squared variance were estimated to assess discriminant and convergent validity. Reliability was assessed using Cronbach's alpha coefficient (α = .839 and .831), composite reliability (CR = .845 and .832), Theta (θ = .893 and .867), and McDonald Omega (Ω = .796 and .743). The analysis indicated a two-factor solution. Reliability and discriminant validity of the factors was established. Findings revealed that the present scale was a valid and reliable instrument that can be used in assessment of death anxiety in Iranian patients with end-stage renal disease.

Stringent long-term control of blood glucose concentration in patients with insulin-dependent diabetes mellitus (IDDM) can decrease albuminuria, presumably forestalling development of renal insufficiency. Personality characteristics may influence a diabetic patient's ability and willingness to follow a prescribed regimen to achieve glycemic control. This study investigated the relationship of 2 personality factors to renal deterioration time (from initiation of insulin therapy to renal failure) in 85 patients with IDDM and end-stage renal disease. Persons moderate in the personality trait of neuroticism and high in conscientiousness had renal deterioration times that were 12 years longer than persons with either high or low neuroticism and low conscientiousness, presumably because of better self-care. The implications of this study's findings are discussed.

Cardiovascular Disease in Patients with End-Stage Renal Disease on Hemodialysis

PubMed Central

Aoki, Jiro; Ikari, Yuji

2017-01-01

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

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. PMID:26469976

The burden of HIV disease has shifted from traditional AIDS-defining illnesses to serious non-AIDS-defining comorbid conditions. Research aimed at improving HIV-related comorbid disease outcomes requires well-defined, verified clinical endpoints. We developed methods to ascertain and verify end-stage renal disease (ESRD) and end-stage liver disease (ESLD) and validated screening algorithms within the largest HIV cohort collaboration in North America (NA-ACCORD). Individuals who screened positive among all participants in twelve cohorts enrolled between January 1996 and December 2009 underwent medical record review to verify incident ESRD or ESLD using standardized protocols. We randomly sampled 6% of contributing cohorts to determine the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of ESLD and ESRD screening algorithms in a validation subcohort. Among 43,433 patients screened for ESRD, 822 screened positive of which 620 met clinical criteria for ESRD. The algorithm had 100% sensitivity, 99% specificity, 82% PPV, and 100% NPV for ESRD. Among 41,463 patients screened for ESLD, 2,024 screened positive of which 645 met diagnostic criteria for ESLD. The algorithm had 100% sensitivity, 95% specificity, 27% PPV, and 100% NPV for ESLD. Our methods proved robust for ascertainment of ESRD and ESLD in persons infected with HIV.

Studies on fever of unknown origin (FUO) in patients of chronic kidney disease and end stage renal disease patients on dialysis were not many. In this study, we used 18 F-FDG PET/CT scan whole body survey for detection of hidden infection, in patients on dialysis, labelled as FUO. In this retrospective study, 20 patients of end stage renal disease on dialysis were investigated for the cause of FUO using 18F-FDG PET/CT scan. All these patients satisfied the definition of FUO as defined by Petersdorf and Beeson. Any focal abnormal site of increased FDG concentration detected by PET/CT, either a solitary or multiple lesions was documented and at least one of the detected abnormal sites of radio tracer concentration was further examined for histopathology. All patients were on renal replacement therapy. Of these, 18 were on hemodialysis and two were on peritoneal dialysis. 18F-FDG PET/CT scan showed metabolically active lesions in 15 patients and metabolically quiescent in five patients. After 18F-FDG PET/CT scan all, but one patient had a change in treatment for fever. Anti-tuberculous treatment was given in 15 patients, antibiotics in four patients and anti-malaria treatment in one patient. The present study is first study of 18F-FDG PET/CT scan in patients of end stage renal disease on dialysis with FUO. The study showed that the 18 F FDG PET/CT scan may present an opportunity to attain the diagnosis in end stage renal disease patients on dialysis with FUO. © 2016 International Society for Hemodialysis.

High dietary phosphorus intake has deleterious consequences for renal patients and is possibly harmful for the general public as well. To prevent hyperphosphatemia, patients with end-stage renal disease limit their intake of foods that are naturally high in phosphorus. However, phosphorus-containing additives are increasingly being added to processed and fast foods. The effect of such additives on serum phosphorus levels is unclear. To determine the effect of limiting the intake of phosphorus-containing food additives on serum phosphorus levels among patients with end-stage renal disease. Cluster randomized controlled trial at 14 long-term hemodialysis facilities in northeast Ohio. Two hundred seventy-nine patients with elevated baseline serum phosphorus levels (>5.5 mg/dL) were recruited between May and October 2007. Two shifts at each of 12 large facilities and 1 shift at each of 2 small facilities were randomly assigned to an intervention or control group. Intervention participants (n=145) received education on avoiding foods with phosphorus additives when purchasing groceries or visiting fast food restaurants. Control participants (n=134) continued to receive usual care. Change in serum phosphorus level after 3 months. At baseline, there was no significant difference in serum phosphorus levels between the 2 groups. After 3 months, the decline in serum phosphorus levels was 0.6 mg/dL larger among intervention vs control participants (95% confidence interval, -1.0 to -0.1 mg/dL). Intervention participants also had statistically significant increases in reading ingredient lists (P<.001) and nutrition facts labels (P = .04) but no significant increase in food knowledge scores (P = .13). Educating end-stage renal disease patients to avoid phosphorus-containing food additives resulted in modest improvements in hyperphosphatemia. clinicaltrials.gov Identifier: NCT00583570.

This study analyzed the results of bilateral nephrectomy in 14 patients with end-stage renal disease (ESRD) and chronic active pyelonephritis. Seven patients had urosepsis, and 10 patients had a purulent form of pyelonephritis, which was one-sided in 7 of them. In the early postoperative period, on average, after 9.3 days, 9 patients died. Statistically significant risk factors for death were: chronic hemodialysis, long-term antibiotic therapy, and existing sepsis. Intraoperative complications and postoperative morbidity were not significantly associated with death. The study results imply the need of differentiated approach to bilateral nephrectomy in patients with ESRD and risk factors for fatal outcome. It must be performed on the strong indications since the intervention does not lead to eradication of sepsis. It is advisable to perform "preventive, sanation" bilateral nephrectomy in the "cold period" in patients at risk for developing urosepsis.

This paper provides a survival analysis of End Stage Renal Disease (ESRD) under Kaplan-Meier Estimates and Weibull Distribution. The data were obtained from the records of V. L. MakabaliMemorial Hospital with respect to time t (patient's age), covariates such as developed secondary disease (Pulmonary Congestion and Cardiovascular Disease), gender, and the event of interest: the death of ESRD patients. Survival and hazard rates were estimated using NCSS for Weibull Distribution and SPSS for Kaplan-Meier Estimates. These lead to the same conclusion that hazard rate increases and survival rate decreases of ESRD patient diagnosed with Pulmonary Congestion, Cardiovascular Disease and both diseases with respect to time. It also shows that female patients have a greater risk of death compared to males. The probability risk was given the equation R = 1 — e-H(t) where e-H(t) is the survival function, H(t) the cumulative hazard function which was created using Cox-Regression.

Tissue and plasma concentrations of pentose-derived glycation end-products ("pentosidine") are elevated in diabetic patients with normal renal function and in both diabetic and nondiabetic patients with end-stage renal disease. To determine the effects of correcting hyperglycemia and/or renal failure on the accumulation of pentosidine, we used reverse phase and ion exchange high performance liquid chromatography to measure this advanced glycation end-product in plasma proteins of diabetic and nondiabetic transplant recipients at various time intervals after kidney-pancreas or kidney transplantation. Changes in plasma pentosidine levels after transplantation were compared to changes in simultaneously obtained glycohemoglobin levels. Both kidney and kidney-pancreas transplantation were accompanied by a dramatic, but incomplete, reduction of plasma pentosidine concentrations within three months of transplantation. Kidney-pancreas transplantation resulted in normal glycohemoglobin levels within three months but offered no advantage over kidney transplantation alone in the partial correction of plasma pentosidine levels. There was no correlation between posttransplant plasma pentosidine and glycohemoglobin levels in either diabetic or nondiabetic transplant recipients. We conclude that renal failure is the major factor accounting for the accumulation of pentosidine in both diabetic and nondiabetic patients with end-stage renal disease. Restoration of euglycemia after kidney-pancreas transplantation provides no additional benefit in reducing plasma pentosidine levels to that achieved by correction of renal failure after kidney transplantation alone.

Heparin-based hydrogels induce human renal tubulogenesis in vitro.

Dialysis or kidney transplantation is the only therapeutic option for end stage renal disease. Accordingly, there is a large unmet clinical need for new causative therapeutic treatments. Obtaining robust models that mimic the complex nature of the human kidney is a critical step in the development of new therapeutic strategies. Here we establish a synthetic in vitro human renal tubulogenesis model based on a tunable glycosaminoglycan-hydrogel platform. In this system, renal tubulogenesis can be modulated by the adjustment of hydrogel mechanics and degradability, growth factor signaling, and the presence of insoluble adhesion cues, potentially providing new insights for regenerative therapy. Different hydrogel properties were systematically investigated for their ability to regulate renal tubulogenesis. Hydrogels based on heparin and matrix metalloproteinase cleavable peptide linker units were found to induce the morphogenesis of single human proximal tubule epithelial cells into physiologically sized tubule structures. The generated tubules display polarization markers, extracellular matrix components, and organic anion transport functions of the in vivo renal proximal tubule and respond to nephrotoxins comparable to the human clinical response. The established hydrogel-based human renal tubulogenesis model is thus considered highly valuable for renal regenerative medicine and personalized nephrotoxicity studies. The only cure for end stage kidney disease is kidney transplantation. Hence, there is a huge need for reliable human kidney models to study renal regeneration and establish alternative treatments. Here we show the development and application of an in vitro human renal tubulogenesis model using heparin-based hydrogels. To the best of our knowledge, this is the first system where human renal tubulogenesis can be monitored from single cells to physiologically sized tubule structures in a tunable hydrogel system. To validate the efficacy of our model as a drug toxicity platform, a chemotherapy drug was incubated with the model, resulting in a drug response similar to human clinical pathology. The established model could have wide applications in the field of nephrotoxicity and renal regenerative medicine and offer a reliable alternative to animal models.

Sterols, bile acids and their receptors have been involved in diabetic nephropathy. The ATP-binding cassette transporters G5 and G8 (ABCG5 and ABCG8) play an important role in intestinal sterol absorption and bile acid secretion. The aim of our study was to assess the associations between two ABCG8 coding polymorphisms, T400K and D19H, and the incidence of renal events in type 2 diabetic subjects. Participants were the 3137 French type 2 diabetic subjects with micro- or macro-albuminuria from the genetic substudy of the DIABHYCAR trial. The mean duration of follow-up was 4years. Renal events were defined as a doubling of serum creatinine concentration or end-stage renal disease at follow-up. We then used a second population (DIAB2NEPHROGENE) of 2140 type 2 diabetic patients for the purpose of validation. In DIABHYCAR, the 400K allele was significantly associated with a higher risk of incident renal events in a multiple adjusted model (HR: 1.75 [95% CI 1.20-2.56], P=0.003). This association was still significant after further adjustments for baseline values of estimated glomerular filtration rate and urinary albumin excretion. In the validation population, the 400K allele was associated with the prevalence of end-stage renal disease (OR=2.01 [95% CI 1.15-3.54], P=0.015). No significant association was found between the D19H polymorphism and the risk of diabetic nephropathy. A polymorphism of the sterol transporter ABCG8 has been associated with the prevalence of end-stage renal disease and with the incidence of new renal events in type 2 diabetic patients.

Primary hyperoxaluria type 1 is an autosomal recessive inborn error of metabolism due to liver-specific peroxisomal enzyme alanine-glyoxylate transaminase deficiency. Here, we describe two unrelated patients who were diagnosed to have primary hyperoxaluria. Homozygous c.445_452delGTGCTGCT (p.L151Nfs*14) (Transcript ID: ENST00000307503; human genome assembly GRCh38.p2) (HGMD ID CD073567) mutation was detected in both the patients and the parents were found to be heterozygous carriers. Our patients developed end-stage renal disease at 23 years and 35 years of age. However, in the largest series published from OxalEurope cohort, the median age of end-stage renal disease for null mutations carriers was 9.9 years, which is much earlier than our cases. Our patients had slower progressions as compared to three unrelated patients from North India and Pakistan, who had homozygous c.302T>C (p.L101P) (HGMD ID CM093792) mutation in exon 2. Further, patients need to be studied to find out if c.445_452delGTGCTGCT mutation represents a founder mutation in Southern India. PMID:27512303

Primary hyperoxaluria type 1 is a rare autosomal-recessive disease caused by the deficient activity of the liver specific enzyme alanine-glyoxylate aminotransferase. Increased endogenous oxalate production induces severe hyperoxaluria, recurrent urolithiasis, progressive nephrocalcinosis and renal failure. Here we report a 6 month old boy who presented with vomiting and decreased urine volume. He was diagnosed with chronic kidney failure at 4 months of age and peritoneal dialysis was introduced at a local hospital. His parents were third degree cousins and family history revealed 2 maternal cousins who developed end stage renal disease during childhood. When he was admitted to our hospital, laboratory studies were consistent with end stage renal disease, ultrasound showed bilateral massive nephrocalcinosis. As clinical presentation was suggestive for primary hyperoxaluria type 1, plasma oxalate was determined and found extremely elevated. Genetic testing proved diagnosis by showing a disease causing homozygous mutation (AGXT-gene: c.971_972delT). The patient was put on pyridoxine treatment and aggressive dialysis programme. In conclusion; progressive renal failure in infancy with massive nephrocalcinosis, especially if accompanied by consanguinity and family history, should always raise the suspicion of PH type 1. Increased awareness of the disease would help physicians in both treating the patients and guiding the families who have diseased children and plan to have further pregnancies. © Georg Thieme Verlag KG Stuttgart · New York.

End-stage renal failure (ESRD) is more than a typical chronic disease. Its treatment includes features which arguably make this condition unique. Selected psychosomatic aspects of ESRD are reviewed, including psychiatric morbidity, patients' adherence to their treatments, quality of life and the emotional impact on staff involved in treating patients with ESRD. Rather than presenting a comprehensive review of the results of published research, particular emphasis is laid on the critical appraisal of the methodology of published studies, to examine the extent to which these have provided answers to clinically important questions.

Background Dialysis therapy for end-stage renal disease (ESRD) continues to be the readily available renal replacement option in developing countries. While the impact of rural/remote dwelling on mortality among dialysis patients in developed countries is known, it remains to be defined in sub-Saharan Africa. Methods A single-center database of end-stage renal disease patients on chronic dialysis therapies treated between 2007 and 2014 at the Polokwane Kidney and Dialysis Centre (PKDC) of the Pietersburg Provincial Hospital, Limpopo South Africa, was retrospectively reviewed. All-cause, cardiovascular, and infection-related mortalities were assessed and associated baseline predictors determined. Results Of the 340 patients reviewed, 52.1% were male, 92.9% were black Africans, 1.8% were positive for the human immunodeficiency virus (HIV), and 87.5% were rural dwellers. The average distance travelled to the dialysis centre was 112.3 ± 73.4 Km while 67.6% of patients lived in formal housing. Estimated glomerular filtration rate (eGFR) at dialysis initiation was 7.1 ± 3.7 mls/min while hemodialysis (HD) was the predominant modality offered (57.1%). Ninety-two (92) deaths were recorded over the duration of follow-up with the majority (34.8%) of deaths arising from infection-related causes. Continuous ambulatory peritoneal dialysis (CAPD) was a significant predictor of all-cause mortality (HR: 1.62, CI: 1.07–2.46) and infection-related mortality (HR: 2.27, CI: 1.13–4.60). On multivariable cox regression, CAPD remained a significant predictor of all-cause mortality (HR: 2.00, CI: 1.29–3.10) while the risk of death among CAPD patients was also significantly modified by diabetes mellitus (DM) status (HR: 4.99, CI: 2.13–11.71). Conclusion CAPD among predominantly rural dwelling patients in the Limpopo province of South Africa is associated with an increased risk of death from all-causes and infection-related causes.

The anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis with renal involvement are associated with high morbi-mortality. In this study we analyse if the prognosis of these diseases have improved in recent years, and which factors influence the outcomes. Retrospective single-centre observational study, which included all patients diagnosed with microscopic polyangiitis and granulomatosis with polyangiitis with renal involvement in the last 25 years. Demographic, clinical and biochemical parameters of prognostic interest were recorded. The differences between four chronological periods were analysed, along with the determinants of a poor outcome (death or end-stage renal disease). Eighty-nine patients were included (mean age 64±15 years). Sixty-four patients (72%) had microscopic polyangiitis and 25 (28%) granulomatosis with polyangiitis. During the study period, 37 (42%) patients died. Through Cox regression analysis, the best determinants of mortality were the initial glomerular filtration rate (HR 0.911; P=.003), Charlson comorbidity index (HR 1.513; P<.0001) and tobacco smoking (HR 1.816; P=.003). 35% developed end-stage renal disease, and the best determinants (by competing-risk regression) were: initial glomerular filtration rate (sub-hazard ratio [SHR]: 0.791; P<.0001), proteinuria (SHR: 1.313; P<.0001), and smoking status (SHR: 1.848; P=.023). No differences were found in patients' mortality or renal survival between the different study periods. Prognosis of anti-neutrophil cytoplasm antibodies vasculitis with renal involvement treated with conventional immunosuppressive therapy remains unsatisfactory, and continues to have increased long-term complications and mortality.

To describe the experiences of family caregivers providing care for patients living with End-Stage Renal Disease in Nigeria BACKGROUND: Family caregiving is where an unpaid volunteer, usually a close family member, attends to the needs of a loved one with a chronic, disabling illness within the home. Much research has been conducted in the area of family caregiving in high-income countries. However, the same cannot be said for many of the low-resource, multicultural African countries. Qualitative descriptive study. This qualitative descriptive study used manifest content analysis to analyse data from semi-structured, individual interviews, with 15 purposively selected family caregivers. Two tertiary institutions providing renal care in South-Western Nigeria: the research setting for this study. Five categories were identified, and these included disconnectedness with self and others, never-ending burden, 'a fool being tossed around', obligation to care and promoting a closer relationship. Experiences associated with the caregiving of patients diagnosed with End-Stage Renal Disease evoked a number of emotions from the family caregivers, and the study revealed that caregiving imposed some burdens that are specific to low-resource countries on participants. Nurses need to engage family caregivers on disease-specific teachings that might promote understanding of the disease process and role expectation. Family caregivers may benefit from social support services. © 2016 John Wiley & Sons Ltd.

To investigate the preventive effects of low-dose proton-pump inhibitors (PPIs) for upper gastrointestinal bleeding (UGIB) in end-stage renal disease. This was a retrospective cohort study that reviewed 544 patients with end-stage renal disease who started dialysis at our center between 2005 and 2013. We examined the incidence of UGIB in 175 patients treated with low-dose PPIs and 369 patients not treated with PPIs (control group). During the study period, 41 patients developed UGIB, a rate of 14.4/1000 person-years. The mean time between the start of dialysis and UGIB events was 26.3 ± 29.6 mo. Bleeding occurred in only two patients in the PPI group (2.5/1000 person-years) and in 39 patients in the control group (19.2/1000 person-years). Kaplan-Meier analysis of cumulative non-bleeding survival showed that the probability of UGIB was significantly lower in the PPI group than in the control group (log-rank test, P < 0.001). Univariate analysis showed that coronary artery disease, PPI use, anti-coagulation, and anti-platelet therapy were associated with UGIB. After adjustments for the potential factors influencing risk of UGIB, PPI use was shown to be significantly beneficial in reducing UGIB compared to the control group (HR = 13.7, 95%CI: 1.8-101.6; P = 0.011). The use of low-dose PPIs in patients with end-stage renal disease is associated with a low frequency of UGIB.

Human platelets carry membrane glycoproteins that control platelet aggregation and activation. A number of clinical studies have suggested that certain polymorphisms of genes encoding these proteins increase the risk for cardiovascular disease. The frequency of gene polymorphisms for the four most common platelet glycoproteins (HPA 1, 2, 3 and 5) was examined and correlated with the primary cause of end-stage renal disease (ESRD) in Greek patients on HD. Fifty-five (55) patients on chronic maintenance haemodialysis (HD) (22 female, 33 male), aged from 23- to 87-years-old, (mean age 66 years), being on dialysis for 53 +/- 34 months, were included in the study. HPA-1, -2, -3, and -5 genotyping was performed using polymerase chain reaction (PCR) amplification with sequence-specific primers (PCR-SSP). Calculated relative frequencies of the alleles were as follows: HPA-1a/b 0.81/0.19, HPA-2a/b 0.92/0.08, HPA-3a/b 0.62/0.38 and HPA-5a/b 0.93/0.07. There was a statistically significant association between the HPA-1b allele and hypertension as the primary cause of ESRD (65% of patients with hypertension vs 23% of all other patients carried the HPA-1b allele, p=0.02, Fisher's exact test). The results suggest that Greek carriers of the HPA-1b allele with hypertension may be at increased risk for developing end-stage renal disease.

Conventionally poorly functioning hydronephrotic kidneys have been removed if they are symptomatic. In our unit, patients are offered renal artery embolization as an alternative treatment option. Patients and Methods: Fifteen patients (11 male, 4 female) with a mean age of 32.9 yr (20-51 yrs) have undergone renal artery embolization for symptomatic hydronephrosis with poor function. Mean follow-up was 64.13 weeks (range 14-200). All patients had loin pain and hydronephrosis. Twelve patients had primary pelvi-ureteric junction obstruction (PUJO). Two patients had poorly functioning hydronephrotic kidneys secondary to chronic calculous obstruction. One patient had chronic pain in an obstructed but reasonably functioningmore » kidney following a previous pyeloplasty for PUJO which demanded intervention. Mean split function on renography was 11% (range 0-46%). Selective renal artery embolization was carried out under antibiotic cover using a 7 Fr balloon occlusion catheter and absolute alcohol, steel coils, and polyvinyl alcohol particles.Results: Nine patients developed post-embolization syndrome of self-limiting pain and pyrexia with no evidence of sepsis. One patient required readmission with this condition. One patient developed a hematoma at the puncture site. Mean hospital stay was 2.3 days. Fourteen patients are happy with the result and are completely pain free. One patient has minor discomfort but is delighted with the result. Nine patients have had follow-up ultrasound confirming resolution of the hydronephrosis. Conclusion: Renal artery embolization is an effective, safe, well-tolerated minimally invasive treatment option in end-stage hydronephrosis and we routinely offer it as an alternative to nephrectomy.« less

To determine the cost effectiveness of one-off population based screening for chronic kidney disease based on estimated glomerular filtration rate. Cost utility analysis of screening with estimated glomerular filtration rate alone compared with no screening (with allowance for incidental finding of cases of chronic kidney disease). Analyses were stratified by age, diabetes, and the presence or absence of proteinuria. Scenario and sensitivity analyses, including probabilistic sensitivity analysis, were performed. Costs were estimated in all adults and in subgroups defined by age, diabetes, and hypertension. Publicly funded Canadian healthcare system. Large population based laboratory cohort used to estimate mortality rates and incidence of end stage renal disease for patients with chronic kidney disease over a five year follow-up period. Patients had not previously undergone assessment of glomerular filtration rate. Lifetime costs, end stage renal disease, quality adjusted life years (QALYs) gained, and incremental cost per QALY gained. Compared with no screening, population based screening for chronic kidney disease was associated with an incremental cost of $C463 (Canadian dollars in 2009; equivalent to about £275, €308, US $382) and a gain of 0.0044 QALYs per patient overall, representing a cost per QALY gained of $C104 900. In a cohort of 100 000 people, screening for chronic kidney disease would be expected to reduce the number of people who develop end stage renal disease over their lifetime from 675 to 657. In subgroups of people with and without diabetes, the cost per QALY gained was $C22 600 and $C572 000, respectively. In a cohort of 100 000 people with diabetes, screening would be expected to reduce the number of people who develop end stage renal disease over their lifetime from 1796 to 1741. In people without diabetes with and without hypertension, the cost per QALY gained was $C334 000 and $C1 411 100, respectively. Population based screening for chronic kidney disease with assessment of estimated glomerular filtration rate is not cost effective overall or in subgroups of people with hypertension or older people. Targeted screening of people with diabetes is associated with a cost per QALY that is similar to that accepted in other interventions funded by public healthcare systems.

Hypovitaminosis D, neighborhood poverty, and progression of chronic kidney disease in disadvantaged populations.

In the United States, there are significant racial disparities in the incidence and prevalence of end-stage renal disease. The disparities are greatest for the Blacks and the magnitude of disparity is significantly greater than is evident from the incidence and prevalence data of end-stage renal disease - early stage chronic kidney disease is less common in Blacks and during that stage, mortality rate is significantly higher for that racial group. Recent studies have identified a genetic predisposition for non-diabetic renal disease among Blacks. However, genetic factors explain only part of the higher risk and the racial disparities are a result of a complex interplay of biology and sociology. Herein we focus on two factors and their role in explaining the higher risk for progression of chronic kidney disease among Blacks - one biologic (vitamin D deficiency) and one sociologic (neighborhood poverty). A greater Understanding of these factors is important in order to reduce the racial disparities in the United States.

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.

Among patients in the United States with chronic kidney disease, black patients are at increased risk for end-stage renal disease, as compared with white patients. In two studies, we examined the effects of variants in the gene encoding apolipoprotein L1 (APOL1) on the progression of chronic kidney disease. In the African American Study of Kidney Disease and Hypertension (AASK), we evaluated 693 black patients with chronic kidney disease attributed to hypertension. In the Chronic Renal Insufficiency Cohort (CRIC) study, we evaluated 2955 white patients and black patients with chronic kidney disease (46% of whom had diabetes) according to whether they had 2 copies of high-risk APOL1 variants (APOL1 high-risk group) or 0 or 1 copy (APOL1 low-risk group). In the AASK study, the primary outcome was a composite of end-stage renal disease or a doubling of the serum creatinine level. In the CRIC study, the primary outcomes were the slope in the estimated glomerular filtration rate (eGFR) and the composite of end-stage renal disease or a reduction of 50% in the eGFR from baseline. In the AASK study, the primary outcome occurred in 58.1% of the patients in the APOL1 high-risk group and in 36.6% of those in the APOL1 low-risk group (hazard ratio in the high-risk group, 1.88; P<0.001). There was no interaction between APOL1 status and trial interventions or the presence of baseline proteinuria. In the CRIC study, black patients in the APOL1 high-risk group had a more rapid decline in the eGFR and a higher risk of the composite renal outcome than did white patients, among those with diabetes and those without diabetes (P<0.001 for all comparisons). Renal risk variants in APOL1 were associated with the higher rates of end-stage renal disease and progression of chronic kidney disease that were observed in black patients as compared with white patients, regardless of diabetes status.

PASH syndrome (pyoderma gangrenosum, acne, and suppurative hidradenitis) forms part of the spectrum of autoinflammatory diseases. We report an unusual case of PASH syndrome in a patient with end-stagerenal disease (ESRD) who was successfully treated with the tumor necrosis factor inhibitor, adalimumab. The case underscores the challenges associatedwith the treatment of PASH syndrome as well as the ongoing search to establish a genetic basis for the syndrome. Renal impairment has been reported in association with pyoderma gangrenosum but has notbeen described in PASH syndrome. We believe this to be the first reported case of a patient who developed PASH syndrome in the setting of ESRD.

Sustaining life or prolonging dying? Appropriate choice of conservative care for children in end-stage renal disease: an ethical framework.

Due to technological advances, an increasing number of infants and children are surviving with multi-organ system dysfunction, and some are reaching end-stage renal disease (ESRD). Many have quite limited life expectancies and may not be eligible for kidney transplantation but families request dialysis as alternative. In developed countries where resources are available there is often uncertainty by the medical team as to what should be done. After encountering several of these scenarios, we developed an ethical decision-making framework for the appropriate choice of conservative care or renal replacement therapy in infants and children with ESRD. The framework is a practical tool to help determine if the burdens of dialysis would outweigh the benefits for a particular patient and family. It is based on the four topics approach of medical considerations, quality-of-life determinants, patient and family preferences and contextual features tailored to pediatric ESRD. In this article we discuss the basis of the criteria, provide a practical framework to guide these difficult conversations, and illustrate use of the framework with a case example. While further research is needed, through this approach we hope to reduce the moral distress of care providers and staff as well as potential conflict with the family in these complex decision-making situations.

Infection is the second leading cause of death in end-stage renal disease (ESRD) patients. Prior investigations of acute septic shock in this specific population are limited. We aimed to evaluate the clinical presentation and factors associated with outcome among ESRD patients with acute septic shock. We reviewed patients prospectively enrolled in an emergency department (ED) septic shock treatment pathway registry between January 2014 and May 2016. Clinical and treatment variables for ESRD patients were compared with non-ESRD patients. A second analysis focused on ESRD septic shock survivors and nonsurvivors. Among 4126 registry enrollees, 3564 (86.4%) met inclusion for the study. End-stage renal disease was present in 3.8% (n = 137) of ED septic shock patients. Hospital mortality was 20.4% and 17.1% for the ESRD and non-ESRD septic shock patient groups (p = 0.31). Septic shock patients with ESRD had a higher burden of chronic illness, but similar admission clinical profiles to non-ESRD patients. End-stage renal disease status was independently associated with lower fluid resuscitation dose, even when controlling for severity of illness. Age and admission lactate were independently associated with mortality in ESRD septic shock patients. ESRD patients comprise a small but important portion of patients with ED septic shock. Although presentation clinical profiles are similar to patients without ESRD, ESRD status is independently associated with lower fluid dose and compliance with the 30-mL/kg fluid goal. Hyperlactatemia is a marker of mortality in ESRD septic shock. Copyright © 2017 Elsevier Inc. All rights reserved.

Although renal transplantation has proved a successful treatment for the patients with end-stage renal failure, the therapy is hampered by the problem of serious shortage of donor organs. Regenerative medicine using stem cells, including cell transplantation therapy, needs to be developed to solve the problem. We previously identified the multipotent progenitor cells in the embryonic mouse kidney that can give rise to several kinds of epithelial cells found in adult kidney, such as glomerular podocytes and renal tubular epithelia. Establishing the method to generate the progenitors from human pluripotent stem cells that have the capacity to indefinitely proliferate in vitromore » is required for the development of kidney regeneration strategy. We review the current status of the research on the differentiation of pluripotent stem cells into renal lineages and describe cues to promote this research field.« less

Health-related quality of life in end-stage renal disease patients: the effects of renal rehabilitation.

PubMed

Kouidi, E

2004-05-01

Health-related quality of life (HRQoL) consists of a number of components like functional status, psychological and social functioning, cognition and disease and treatment-related symptoms. End-stage renal disease (ESRD) patients display emotional disturbances, as well as non-adherence to treatment and fluid and food intake, depression, anxiety, social withdrawal and cardiovascular and other co-existing disease morbidity. They have very low functional capacity and physical limitations in their daily activities that affect their mortality and morbidity. Exercise training in ESRD patients is effective in increasing work related activities and important components of their daily life and improving physical functioning. A physical rehabilitation program also leads to a reduction in depression and improvement in family and social interactions. Therefore, renal rehabilitation should be considered as an important therapeutic method for improving physical fitness, social function, well-being and thus health-adjusted quality of life in ESRD patients.

2006-01-01

Rapid and dynamic increase of the number of patients that need different forms of renal replacement therapy can be noticed in the developed countries. This increase is associated with increased number of patients with 'diseases of modern civilization', such as diabetes and hypertension, which lead to kidney complications (e.g. diabetic and hypertensive nephropathy). Improved long-term care (especially diabetic and cardiologic) allows these patients to survive longer and to reach the stage of end-stage renal disease. This leads to increasing age and morbidity of patients treated with dialysis. In many cases, due to extremely advanced level of co-morbidity patients on dialysis are exposed to extreme level of suffering and unacceptably low quality of life. Persistent continuing of renal replacement therapy under such circumstances (with no hope for recovery or improvement) raises also some economical issues, especially in the context of permanent crisis and shortage of resources in health systems of most countries in the world. In this review the current practice concerning withdrawal or withholding of renal replacement therapy as well as some legal and ethical issues of this practice are discussed.

[Cystic renal neoplasms. New entities and molecular findings].

Renal neoplasms with dominant cysts represent a broad spectrum of known as well as novel renal tumor entities. Established renal tumors with dominant cysts include cystic nephroma, mixed epithelial and stromal tumor, synovial sarcoma and multilocular cystic renal cancer (WHO classification 2004). Novel tumor types have recently been reported, which are also characterized by marked cyst formation. Examples are tubulocystic renal cancer and renal cancer in end-stage renal disease. These tumors are very likely to be included in a future WHO classification due to their characteristic phenotype and molecular features. Cysts and clear cell renal cell carcinoma frequently coexist in the kidneys of patients with von Hippel-Lindau disease. Cysts are also a component of many sporadic clear cell renal cell carcinomas. Multilocular cystic renal cell carcinoma is composed almost exclusively of cysts and is regarded as a specific subtype of clear cell renal cancer. Recent molecular findings suggest that clear cell renal cancer may develop via a cyst-dependent mechanism in von Hippel-Lindau syndrome as well as via cyst-independent molecular pathways in sporadic clear cell renal cancer.

Biomarkers for kidney involvement in pediatric lupus

Lupus nephritis (LN), the renal involvement in systemic lupus erythematosus, is currently diagnosed by histopathology obtained by percutaneous renal biopsy and is associated with increased morbidity and mortality in both adults and children. LN is more prevalent and severe in children, requiring aggressive and prolonged immunosuppression. The consequences of the diagnosis and its treatment have devastating long-term effects on the growth, well-being and quality of life of affected children. The paucity of reliable clinical indicators of the presence and severity of renal involvement have contributed to a halt in the reduction of progression to end-stage renal disease in recent years. Here, we discuss the recent development of biomarkers in the management of LN and their role as therapeutic targets. PMID:26079958

Left ventricular assist device (LVAD) and inotrope therapy serve as a bridge to transplant (BTT) or as destination therapy in patients who are not heart transplant candidates. End-stage heart failure patients often have impaired renal function, and renal outcomes after LVAD therapy versus inotrope therapy have not been evaluated. In this study, 169 patients with continuous flow LVAD therapy and 20 patients with continuous intravenous inotrope therapy were analyzed. The two groups were evaluated at baseline and at 3 and 6 months after LVAD or inotrope therapy was started. The incidence of acute kidney injury (AKI), need for renal replacement therapy (RRT), BTT rate, and mortality for 6 months following LVAD or inotrope therapy were studied. Results between the groups were compared using Mann-Whitney U test and Chi-square with continuity correction or Fischer's exact at the significance level of 0.05. Mean glomerular filtration rate (GFR) was not statistically different between the two groups, with P = 0.471, 0.429, and 0.847 at baseline, 3 and 6 months, respectively. The incidence of AKI, RRT, and BTT was not statistically different. Mortality was less in the inotrope group (P < 0.001). Intravenous inotrope therapy in end-stage heart failure patients is non-inferior for mortality, incidence of AKI, need for RRT, and renal function for 6-month follow-up when compared to LVAD therapy. Further studies are needed to compare the effectiveness of inotropes versus LVAD implantation on renal function and outcomes over a longer time period.

The primary objective of this study was to compare the pharmacokinetics of dexmedetomidine in patients with end-stage renal failure and secondary hyperparathyroidism with those in normal individuals. Fifteen patients with end-stage renal failure and secondary hyperparathyroidism (Renal-failure Group) and 8 patients with normal renal and parathyroid gland function (Control Group) received intravenous 0.6 μg/kg dexmedetomidine for 10 minutes before anaesthesia induction. Arterial blood samples for plasma dexmedetomidine concentration analysis were drawn at regular intervals after the infusion was stopped. The pharmacokinetics were analysed using a nonlinear mixed-effect model with NONMEM software. The statistical significance of covariates was examined using the objective function (-2 log likelihood). In the forward inclusion and backward deletion, covariates (age, weight, sex, height, lean body mass [LBM], body surface area [BSA], body mass index [BMI], plasma albumin and grouping factor [renal failure or not]) were tested for significant effects on pharmacokinetic parameters. The validity of our population model was also evaluated using bootstrap simulations. The dexmedetomidine concentration-time curves fitted best with the principles of a two-compartmental pharmacokinetic model. No covariate of systemic clearance further improved the model. The final pharmacokinetic parameter values were as follows: V 1  = 60.6 L, V 2  = 222 L, Cl 1  = 0.825 L/min and Cl 2  = 4.48 L/min. There was no influence of age, weight, sex, height, LBM, BSA, BMI, plasma albumin and grouping factor (renal failure or not) on pharmacokinetic parameters. Although the plasma albumin concentrations (35.46 ± 4.13 vs 44.10 ± 1.12 mmol/L, respectively, P < .05) and dosage of propofol were significantly lower in the Renal-failure Group than in the Control Group (81.68 ± 18.08 vs 63.07 ± 13.45 μg/kg/min, respectively, P < .05), there were no differences in the context-sensitive half-life and the revival time of anaesthesia between the 2 groups. The pharmacokinetics of dexmedetomidine were best described by a two-compartment model in our study. The pharmacokinetic parameters of dexmedetomidine in patients with end-stage renal failure and hyperparathyroidism were similar to those in patients with normal renal function. Further studies of dexmedetomidine pharmacokinetics are recommended to optimize its clinical use. © 2017 John Wiley & Sons Ltd.

There is emerging evidence that exercise training could positively impact several of the cardiovascular risk factors associated with sudden cardiac death amongst patients on haemodialysis. The primary aim of this study is to evaluate the effect of an intradialytic exercise programme on left ventricular mass. Prospective, randomised cluster open-label blinded endpoint clinical trial in 130 patients with end stage renal disease on haemodialysis. Patients will be randomised 1:1 to either 1) minimum of 30 min continuous cycling thrice weekly during dialysis or 2) standard care. The primary outcome is change in left ventricular mass at 6 months, assessed by cardiac MRI (CMR). In order to detect a difference in LV mass of 15 g between groups at 80 % power, a sample size of 65 patients per group is required. Secondary outcome measures include abnormalities of cardiac rhythm, left ventricular volumes and ejection fraction, physical function measures, anthropometric measures, quality of life and markers of inflammation, with interim assessment for some measures at 3 months. This study will test the hypothesis that an intradialytic programme of exercise leads to a regression in left ventricular mass, an important non-traditional cardiovascular risk factor in end stage renal disease. For the first time this will be assessed using CMR. We will also evaluate the efficacy, feasibility and safety of an intradialytic exercise programme using a number of secondary end-points. We anticipate that a positive outcome will lead to both an increased patient uptake into established intradialytic programmes and the development of new programmes nationally and internationally.

Novel Therapeutic Options for the Treatment of Mineral Metabolism Abnormalities in End Stage Renal Disease

PubMed Central

Kendrick, Jessica; Chonchol, Michel

2015-01-01

Abnormalities in mineral metabolism are a universal complication in dialysis patients and are associated with an increased risk of cardiovascular disease and mortality. Hyperphosphatemia, increased fibroblast growth factor 23 levels and secondary hyperparathyroidism are all strongly associated with adverse outcomes in end stage renal disease (ESRD) and most treatment strategies target these parameters. Over the past few years, new therapies have emerged for the treatment of abnormalities of mineral metabolism in ESRD and many are promising. This article will review these new therapeutic options including the potential advantages and disadvantages compared to existing therapies. PMID:26278462

Absence of neoplastic disease in the organ-recipient is required in order to allow organ transplantation. Due to its rarity, no data regarding management of patients with Multiple endocrine neoplasia type 1 (MEN1) and end-stage renal failure candidates for kidney transplantation are available. A 36 year-old man was referred to the present hospital with MEN1, with a neuroendocrine pancreatic tumor and primary hyperparathyroidism and associated Alport syndrome with end stage renal failure. The present study aimed to establish the eligibility of the patient for a kidney transplantation. The neuroendocrine tumor had been treated with duodenopancreatectomy two years earlier and hyperparathyroidism by parathyroidectomy. The review of the literature did not provide data regarding the eligibility for kidney transplantation of patients harboring a neuroendocrine pancreatic tumor in the context of MEN1. Due to the end-stage renal failure, neuroendocrine markers were unreliable and the investigation therefore relied on imaging studies, which were unremarkable. Young age, low-grade tumor, low expression of Ki67, absence of metastatic lymph nodes, onset in the setting of a MEN1 were all positive prognostic factors of the neuroendocrine tumor. Normal serum calcium ruled out persistent primary hyperparathyroidism. Overall, hemodyalisis is known to significantly reduce life expectancy. Benefits of kidney transplantation overcome the risk of neuroendocrine tumor recurrence in a young patient bearing MEN1.

The most common causes of end stage renal failure in 46 children (mean age 11 years, range 4-14) treated between January 1972 and June 1977 were: reflux nephropathy (n = 12), cystinosis (n = 7), focal and segmental glomerulosclerosis (n = 6), and Schönlein-Henoch disease (n = 5). The quality of life, degree of renal function, and height attainment of the 31 survivors were assessed in June 1985, when their mean age was 22 years (range 14-27), using hospital records and a questionnaire designed to highlight social and psychological problems. Twenty six patients had a functioning transplanted kidney. Average growth during treatment for all survivors was normal, but most were disappointed with their 'final height'. Though five patients had some form of disabling bone disease, all 31 could walk and 27 could run. Sixteen (67%) were in full or part time employment and nine were living independently. A group of 32 patients with juvenile onset diabetes treated at this hospital for at least five years were also asked to complete the questionnaire and of these, 17 responded. On average, their data could usefully be compared with those of cases of end stage renal failure. More of the diabetics had jobs, but most sexually mature patients with renal disease were concerned about their physical appearance and had not achieved any stable long term sexual relationships. We suggest that a poor body image resulting in low self esteem may be responsible for the deficiency and believe that further study in this group is warranted.

Treatment of end-stage renal disease with continuous ambulatory peritoneal dialysis in rural Guatemala

A 42-year-old indigenous Maya man presented to a non-profit clinic in rural Guatemala with signs, symptoms and laboratory values consistent with uncontrolled diabetes. Despite appropriate treatment, approximately 18 months after presentation, he was found to have irreversible end-stage renal disease (ESRD) of uncertain aetiology. He was referred to the national public nephrology clinic and subsequently initiated home-based continuous ambulatory peritoneal dialysis. With primary care provided by the non-profit clinic, his clinical status improved on dialysis, but socioeconomic and psychological challenges persisted for the patient and his family. This case shows how care for people with ESRD in low- and middle-income countries requires scaling up renal replacement therapy and ensuring access to primary care, mental healthcare and social work services.

Background Atrial fibrillation (AF) frequently occurs in patients with chronic kidney disease (CKD). However, the long-term impact of development of AF on the risk of adverse renal outcomes in patients with CKD is unknown. In this study, we determined the association between incident AF and risk of end-stage renal disease (ESRD) among adults with CKD. Methods and Results We studied adults with CKD (defined as persistent glomerular filtration rate [eGFR] <60 ml/min/1.73 m2 by the CKD-EPI equation) enrolled in Kaiser Permanente Northern California who were identified between 2002–2010 and who did not have prior ESRD or previously documented AF. Incident AF was identified using primary hospital discharge diagnoses and/or two or more outpatient visits for AF. Incident ESRD was ascertained from a comprehensive health plan registry for dialysis and renal transplant. Among 206,229 adults with CKD, 16,463 developed incident AF. During a mean follow-up of 5.1± 2.5 years, there were 345 cases of ESRD that occurred after development of incident AF (74 per 1000 person-years) compared with 6505 cases of ESRD during periods without AF (64 per 1000 person-years, P<0.001). After adjustment for potential confounders, incident AF was associated with a 67% increase in rate of ESRD (hazard ratio 1.67, 95% confidence interval: 1.46–1.91). Conclusions Incident AF is independently associated with increased risk of developing ESRD in adults with CKD. Further study is needed to identify potentially modifiable pathways through which AF leads to a higher risk of progression to ESRD. PMID:23275377

The diagnosis of Frasier syndrome is based on the association of male pseudohermaphroditism (as a result of gonadal dysgenesis), with steroid-resistant nephrotic syndrome due to focal and segmental glomerular sclerosis (FSGS), which progresses to end-stage renal failure (ESRF) during adolescence or adulthood. Frasier syndrome results from mutations in the Wilms' tumour suppressor gene WT1, which is responsible for alterations in male genital development and podocyte dysfunction. We describe the case of a 7-year-old girl who was referred to the paediatric emergency department with ESRF. Haemodialysis was started immediately because of severe hypertension and hyperkalaemia. In view of the fact that our patient had a past medical history of pseudohermaphroditism, we suspected that the acute presentation in ESRF may be related to a new diagnosis of Frasier syndrome. Our hypothesis was confirmed on examination of the medical records. There had been no medical follow-up for several years and, in particular, no renal imaging or functional assessment had ever been performed. This lack of surveillance explains why our patient presented with ESRF much earlier in this disease than expected and subsequently had to undergo kidney transplantation at a very young age.

Small-vessel vasculitides are associated with antineutrophil cytoplasmic antibodies (ANCAs). Cytoplasmic ANCAs are targeted mainly against proteinase 3 (PR3), whereas myeloperoxidase (MPO) is the major antigen of perinuclear ANCAs. These relapsing vasculitides show heterogeneous clinical pictures, and disease severity may vary broadly from mild local organ manifestation to acute organ failure (eg, renal failure). We tested whether two cytokine polymorphisms in the interleukin-1beta (IL-1beta) and IL-1 receptor antagonist (IL-1ra) genes, known to determine cytokine secretion, are associated with clinical manifestations and outcome of ANCA-associated vasculitides. Polymerase chain reaction and restriction fragment length polymorphism analyses were performed to determine polymorphisms in the IL-1beta and IL-1ra genes in 79 patients with PR3-ANCA, 30 patients with MPO-ANCA vasculitis, and 196 healthy controls. The frequency of the so-called proinflammatory genotype, characterized by high secretion of IL-1beta and low secretion of its antagonist IL-1ra, was increased significantly in patients with PR3-ANCA with end-stage renal disease. Patients with a renal manifestation of PR3-ANCA vasculitis have an increased risk for developing end-stage renal disease when carrying the proinflammatory IL-1beta/IL-1ra genotype. Anti-inflammatory therapy specifically antagonizing the proinflammatory effect of IL-1beta may be a promising treatment for patients with Wegener's granulomatosis with renal manifestations.

Aging veterans and the end-stage renal disease management dilemma in the millennium.

The population of aging veterans with complex multiple medical problems is increasing steadily in developed nations. The life expectancy in an aging population with end-stage renal disease (ESRD) is often compared with terminal malignancy. Renal failure in elderly patients often generates a myriad of complicated issues and the nephrologists are faced with the dilemma of conveying the prognosis of renal failure in elderly patients and also explain the pros and cons of offering a renal replacement therapy. Our objectives were to assess the cumulative survival in veterans with ESRD over 70 years of age and to evaluate the factors considered for either not initiating or withdrawing from dialysis. All veterans above age 70 years, who were being evaluated for possible dialysis therapy over a 5-year period, were included in the study. The cumulative survival rates at 1 year, 3 years and 5 years were 60%, 37%, and 20%, respectively. Tunneled cuffed catheter was the dialysis access in a third of these patients on dialysis adding to the morbidity. Twenty-four patients considered either not initiating or withdrawing from dialysis therapy after consensus agreement from either the patient or the power of attorney. The decision to initiate dialysis therapy should be made considering the social, ethical, and associated comorbid conditions. A decision to not initiate or withdraw dialysis is possible in critically ill elderly patients and if taken judiciously can reduce physical and mental stress of both the patient and their family members.

Although supraphysiological concentrations of urea are known to increase oxidative stress in cultured cells, it is generally thought that the elevated levels of urea in chronic renal failure patients have negligible toxicity. We previously demonstrated that ROS increase intracellular protein modification by O-linked β-N-acetylglucosamine (O-GlcNAc), and others showed that increased modification of insulin signaling molecules by O-GlcNAc reduces insulin signal transduction. Because both oxidative stress and insulin resistance have been observed in patients with end-stage renal disease, we sought to determine the role of urea in these phenotypes. Treatment of 3T3-L1 adipocytes with urea at disease-relevant concentrations induced ROS production, caused insulin resistance, increased expression of adipokines retinol binding protein 4 (RBP4) and resistin, and increased O-GlcNAc–modified insulin signaling molecules. Investigation of a mouse model of surgically induced renal failure (uremic mice) revealed increased ROS production, modification of insulin signaling molecules by O-GlcNAc, and increased expression of RBP4 and resistin in visceral adipose tissue. Uremic mice also displayed insulin resistance and glucose intolerance, and treatment with an antioxidant SOD/catalase mimetic normalized these defects. The SOD/catalase mimetic treatment also prevented the development of insulin resistance in normal mice after urea infusion. These data suggest that therapeutic targeting of urea-induced ROS may help reduce the high morbidity and mortality caused by end-stage renal disease. PMID:19955654

Renal Replacement Therapy in Austere Environments

Yuan, Christina M.; Perkins, Robert M.

2011-01-01

Myoglobinuric renal failure is the classically described acute renal event occurring in disaster environments—commonly after an earthquake—which most tests the ingenuity and flexibility of local and regional nephrology resources. In recent decades, several nephrology organizations have developed response teams and planning protocols to address disaster events, largely focusing on patients at risk for, or with, acute kidney injury (AKI). In this paper we briefly review the epidemiology and outcomes of patients with dialysis-requiring AKI after such events, while providing greater focus on the management of the end-stage renal disease population after a disaster which incapacitates a pre-existing nephrologic infrastructure (if it existed at all). “Austere” dialysis, as such, is defined as the provision of renal replacement therapy in any setting in which traditional, first-world therapies and resources are limited, incapacitated, or nonexistent.

Non-immune hydrops fetalis (NIHF) is a challenging entity as it represents the end stage of several different disorders. Renal and genitourinary causes of NIHF are rare and include congenital renal malformations, tumors and ureter-urethra disorders. Herein, two NIHF cases with different renal causes were presented. The first case that had antenatal NIHF was diagnosed neonatal Bartter syndrome. The second case of NIHF with antenatal large cyst in the surrenal gland area required surgery and ectopic renal cyst was diagnosed. To our best of knowledge, these are the first reports of NIHF associated with neonatal Bartter syndrome and ectopic renal cyst in neonates. Although it may be coincidental, these cases suggest that both neonatal Bartter syndrome and unilateral ectopic renal cyst may cause NIHF development in neonates by several different mechanisms. Therefore, these two rare entities should be suspected in cases of NIHF with similar findings.

Omega-3 fatty acid supplementation as an adjunctive therapy in the treatment of chronic kidney disease: a meta-analysis.

The aim of this study was to evaluate the benefits and risks of omega-3 fatty acid supplementation in patients with chronic kidney disease. A systematic search of articles in PubMed, Embase, the Cochrane Library, and reference lists was performed to find relevant literature. All eligible studies assessed proteinuria, the serum creatinine clearance rate, the estimated glomerular filtration rate, or the occurrence of end-stage renal disease. Standard mean differences with 95% confidence intervals for continuous data were used to estimate the effects of omega-3 fatty acid supplementation on renal function, as reflected by the serum creatinine clearance rate, proteinuria, the estimated glomerular filtration rate, and relative risk. Additionally, a random-effects model was used to estimate the effect of omega-3 fatty acid supplementation on the risk of end-stage renal disease. Nine randomized controlled trials evaluating 444 patients with chronic kidney disease were included in the study. The follow-up duration ranged from 2 to 76.8 months. Compared with no or low-dose omega-3 fatty acid supplementation, any or high-dose omega-3 fatty acid supplementation, respectively, was associated with a lower risk of proteinuria (SMD: -0.31; 95% CI: -0.53 to -0.10; p=0.004) but had little or no effect on the serum creatinine clearance rate (SMD: 0.22; 95% CI: -0.40 to 0.84; p=0.482) or the estimated glomerular filtration rate (SMD: 0.14; 95% CI: -0.13 to 0.42; p=0.296). However, this supplementation was associated with a reduced risk of end-stage renal disease (RR: 0.49; 95% CI: 0.24 to 0.99; p=0.047). In sum, omega-3 fatty acid supplementation is associated with a significantly reduced risk of end-stage renal disease and delays the progression of this disease.

Structural heart disease is highly prevalent in patients with chronic kidney disease requiring dialysis. More than 80% of patients with end-stage renal disease (ESRD) are reported to have cardiovascular disease. This observation has enormous clinical relevance because the leading causes of death for patients with ESRD are of cardiovascular disease etiology, including heart failure, myocardial infarction, and sudden cardiac death. The 2 systems most commonly used to classify the severity of heart failure are the New York Heart Association (NYHA) functional classification and the American Heart Association (AHA)/American College of Cardiology (ACC) staging system. With rare exceptions, patients with ESRD who do not receive renal replacement therapy (RRT) develop signs and symptoms of heart failure, including dyspnea and edema due to inability of the severely diseased kidneys to excrete sodium and water. Thus, by definition, nearly all patients with ESRD develop a symptomatology consistent with heart failure if fluid removal by RRT is delayed. Neither the AHA/ACC heart failure staging nor the NYHA functional classification system identifies the variable symptomatology that patients with ESRD experience depending upon whether evaluation occurs before or after fluid removal by RRT. Consequently, the incidence, severity, and outcomes of heart failure in patients with ESRD are poorly characterized. The 11th Acute Dialysis Quality Initiative has identified this issue as a critical unmet need for the proper evaluation and treatment of heart failure in patients with ESRD. We propose a classification schema based on patient-reported dyspnea assessed both pre- and post-ultrafiltration, in conjunction with echocardiography.

Hospice care is most appropriate when a patient no longer benefits from curative treatment and has limited life expectancy. These patients may suffer from any type of life-limiting illness, including end-stage cancer, end-stage heart disease, end-stage renal failure, AIDS, and Alzheimer's disease, among other illnesses. Patients are managed on their pain and symptoms and home hospice care manages these patients in the comfort of their own home, enabling patients to spend their last days with dignity and have a good quality of life. To describe the home hospice patients at HCA Hospice Care (HHC) Singapore from 2000 to 2010. Description of home care patients in terms of their sociodemographic profile and diagnosis at admission. We reviewed the Electronic Medical Records of patients admitted into HHC from 2000 to 2010. Patients had multiple admissions into HHC home hospice as identified in the Electronic Medical Records (EMR) between January 1, 2000, and December 31, 2010, but we only selected patient's first admission into HHC home hospice for this analysis. Of the 25,065 patients in the entire samples, 47.3% were males, 65.2% were married, and 84.3% were Chinese. 50.9% of the patients died at home, 75.5% were referred from public hospitals, 53.9% of primary caregivers were children, and the mean age of the patients was 68.0 years. Among all cancer patients admitted into HHC home hospice, lung cancer (23.6%) was the most common principal diagnosis for admission, followed by colorectal (10.5%) and liver cancers (7.7%). Among noncancer patients, renal failure (7.0%) was the most common diagnosis. Among male patients admitted into HHC home hospice, lung cancer (29.6%) was the most common diagnosis, followed by liver cancer (10.8%), colorectal cancer (10.0%), and end-stage renal failure (5.5%). For female patients, lung cancer (16.9%) was the most common diagnosis, followed by breast cancer (15.9%), colorectal cancer (11.0%), and end-stage renal failure (8.7%). Ten-year trends of the sociodemographic profile and diagnosis at admission were further analyzed to determine home hospice services utilization and the needs of the home care patients. With an increasing emphasis to encourage aging and dying in the community and more attention given to building up the home hospice industry's capacity and capability, it is important to understand the profile of the patients who have been utilizing home hospice services. This also helps to plan and develop similar services in other parts of the world.

Renal transplantation is the optimal treatment for selected patients with end-stage renal disease (ESRD). However, the survival benefit of renal transplantation among patients with ESRD attributed to granulomatosis with polyangiitis (GPA) is unknown. We identified patients from the United States Renal Data System with ESRD due to GPA (ESRD-GPA) between 1995 and 2014. We restricted our analysis to waitlisted subjects to evaluate the impact of transplantation on mortality. We followed patients until death or the end of follow-up. We compared the relative risk (RR) of all-cause and cause-specific mortality in patients who received a transplant versus non-transplanted patients using a pooled logistic regression model with transplantation as a time-varying exposure. During the study period, 1525 patients were waitlisted and 946 received a renal transplant. Receiving a renal transplant was associated with a 70% reduction in the risk of all-cause mortality in multivariable-adjusted analyses (RR=0.30, 95% CI 0.25 to 0.37), largely attributed to a 90% reduction in the risk of death due to cardiovascular disease (CVD) (RR=0.10, 95% 0.06-0.16). Renal transplantation is associated with a significant decrease in all-cause mortality among patients with ESRD attributed to GPA, largely due to a decrease in the risk of death to CVD. Prompt referral for transplantation is critical to optimise outcomes for this patient population. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Anxiety is the most frequent emotional reaction to the chronic somatic disease. However, little is known about anxiety and coping strategies in patients with end-stage renal disease (ESRD) undergoing renal replacement therapies (RRTs). The purpose of the study was to assess the intensity and determinants of anxiety in patients treated with different RRTs in comparison with end-stage breast cancer patients and healthy controls. The study involved (1) ESRD patients undergoing different RRTs: 32 renal transplant recipients, 31 maintenance haemodialysis and 21 chronic peritoneal dialysis patients, (2) women with end-stage breast cancer (n = 25) and (3) healthy persons (n = 55). We used State-Trait Anxiety Inventory, Scale of Personal Religiousness, Mental Adjustment to Cancer Scale, Rotterdam Symptom Checklist with reference to medical history. The data thus obtained were analysed using the analysis of variance, the Tukey's HSD post hoc test and Spearman's rank correlation coefficient. Both ESRD and breast cancer patients revealed higher level of anxiety state and trait than healthy controls; however, there was no statistically significant difference found between both findings. There was a tendency towards higher levels of anxiety state in breast cancer patients when compared to ESRD patients undergoing the RRT treatment and for both groups non-constructive coping strategies correlated with the levels of anxiety state. With ESRD patients undergoing RRTs, the intensity of anxiety state did not depend on the mode of treatment but on the correlation between the levels of anxiety and the general quality of their life, psychological condition and social activity. In patients with advanced somatic disease (ESRD and end-stage breast cancer), non-constructive strategies of coping with the disease require further evaluation and possibly psychological support.

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

Introduction Renal interstitial fibrosis (RIF) is a significant cause of end-stage renal failure. The goal of this study was to characterize the distribution of transplanted induced autologous stem cells in a rabbit model of renal interstitial fibrosis and evaluate its therapeutic efficacy for treatment of renal interstitial fibrosis. Methods A rabbit model of renal interstitial fibrosis was established. Autologous fibroblasts were cultured, induced and labeled with green fluorescent protein (GFP). These labeled stem cells were transplanted into the renal artery of model animals at 8 weeks. Results Eight weeks following transplantation of induced autologous stem cells, significant reductions (P < 0.05) were observed in serum creatinine (SCr) (14.8 ± 1.9 mmol/L to 10.1 ± 2.1 mmol/L) and blood urea nitrogen (BUN) (119 ± 22 µmol/L to 97 ± 13 µmol/L), indicating improvement in renal function. Conclusions We successfully established a rabbit model of renal interstitial fibrosis and demonstrated that transplantation of induced autologous stem cells can repair kidney damage within 8 weeks. The repair occurred by both inhibition of further development of renal interstitial fibrosis and partial reversal of pre-existing renal interstitial fibrosis. These beneficial effects lead to the development of normal tissue structure and improved renal function. PMID:24367598

Stroke and Chronic Kidney Disease: Epidemiology, Pathogenesis, and Management Across Kidney Disease Stages

Summary Cerebrovascular disease and stroke are very common at all stages of chronic kidney disease (CKD), likely representing both shared risk factors as well as synergy among risk factors. More subtle ischemic brain lesions may be particularly common in the CKD population, with subtle manifestations including cognitive impairment. For individuals with nondialysis CKD, the prevention, approach to, diagnosis, and management of stroke is similar to the general, non-CKD population. For individuals with end-stage renal disease, far less is known regarding the prevention of stroke. Stroke prophylaxis using warfarin in dialysis patients with atrial fibrillation in particular remains of uncertain benefit. End-stage renal disease patients can be managed aggressively in the setting of acute stroke. Outcomes after stroke at all stages of CKD are poor, and improving these outcomes should be the subject of future clinical trials. PMID:26355250

Hypoxia: The Force that Drives Chronic Kidney Disease

2016-01-01

In the United States the prevalence of end-stage renal disease (ESRD) reached epidemic proportions in 2012 with over 600,000 patients being treated. The rates of ESRD among the elderly are disproportionally high. Consequently, as life expectancy increases and the baby-boom generation reaches retirement age, the already heavy burden imposed by ESRD on the US health care system is set to increase dramatically. ESRD represents the terminal stage of chronic kidney disease (CKD). A large body of evidence indicating that CKD is driven by renal tissue hypoxia has led to the development of therapeutic strategies that increase kidney oxygenation and the contention that chronic hypoxia is the final common pathway to end-stage renal failure. Numerous studies have demonstrated that one of the most potent means by which hypoxic conditions within the kidney produce CKD is by inducing a sustained inflammatory attack by infiltrating leukocytes. Indispensable to this attack is the acquisition by leukocytes of an adhesive phenotype. It was thought that this process resulted exclusively from leukocytes responding to cytokines released from ischemic renal endothelium. However, recently it has been demonstrated that leukocytes also become activated independent of the hypoxic response of endothelial cells. It was found that this endothelium-independent mechanism involves leukocytes directly sensing hypoxia and responding by transcriptional induction of the genes that encode the β2-integrin family of adhesion molecules. This induction likely maintains the long-term inflammation by which hypoxia drives the pathogenesis of CKD. Consequently, targeting these transcriptional mechanisms would appear to represent a promising new therapeutic strategy. PMID:26847481

Diabetic kidney disease is a common complication of type 1 and type 2 diabetes and is the primary cause of end-stage renal disease in developed countries. Early detection of diabetic kidney disease will facilitate early intervention aimed at reducing the rate of progression to end-stage renal disease. Diabetic kidney disease has been traditionally classified based on the presence of albuminuria. More recently estimated glomerular filtration rate has also been incorporated into the staging of diabetic kidney disease. While albuminuric diabetic kidney disease is well described, the phenotype of non-albuminuric diabetic kidney disease is now widely accepted. An association between markers of inflammation and diabetic kidney disease has previously been demonstrated. Effector molecules of the innate immune system including C-reactive protein, interleukin-6, and tumor necrosis factor-α are increased in patients with diabetic kidney disease. Furthermore, renal infiltration of neutrophils, macrophages, and lymphocytes are observed in renal biopsies of patients with diabetic kidney disease. Similarly high serum neutrophil and low serum lymphocyte counts have been shown to be associated with diabetic kidney disease. The neutrophil-lymphocyte ratio is considered a robust measure of systemic inflammation and is associated with the presence of inflammatory conditions including the metabolic syndrome and insulin resistance. Cross-sectional studies have demonstrated a link between high levels of the above inflammatory biomarkers and diabetic kidney disease. Further longitudinal studies will be required to determine if these readily available inflammatory biomarkers can accurately predict the presence and prognosis of diabetic kidney disease, above and beyond albuminuria, and estimated glomerular filtration rate.

Current pharmacotherapy for the treatment of crescentic glomerulonephritis.

PubMed

Tam, Frederick W K

2006-11-01

Glomerulonephritis is an important cause of end-stage renal disease. Crescentic glomerulonephritis is the most severe form of glomerulonephritis and, if untreated, patients will develop renal failure within days or weeks of diagnosis. Current immunotherapy consists of corticosteroids, cytotoxic drugs and plasma exchange. Challenges include minimising toxicity of therapy, preventing relapse in antineutrophil cytoplasmic antibodies-associated vasculitis and finding an effective treatment for crescentic IgA nephropathy. There are opportunities for more specific therapies using monoclonal antibodies to T cells (and their co-stimulatory receptors), B cells and cytokines, or pharmacological inhibitors of signal transduction. Their efficacy and safety remain to be established with controlled clinical trials. Recent development of urinary cytokine measurement provides a noninvasive biomarker of renal disease activity, which is useful in monitoring response to therapy and assessing prognosis.

Background Left ventricular assist device (LVAD) and inotrope therapy serve as a bridge to transplant (BTT) or as destination therapy in patients who are not heart transplant candidates. End-stage heart failure patients often have impaired renal function, and renal outcomes after LVAD therapy versus inotrope therapy have not been evaluated. Methods In this study, 169 patients with continuous flow LVAD therapy and 20 patients with continuous intravenous inotrope therapy were analyzed. The two groups were evaluated at baseline and at 3 and 6 months after LVAD or inotrope therapy was started. The incidence of acute kidney injury (AKI), need for renal replacement therapy (RRT), BTT rate, and mortality for 6 months following LVAD or inotrope therapy were studied. Results between the groups were compared using Mann-Whitney U test and Chi-square with continuity correction or Fischer’s exact at the significance level of 0.05. Results Mean glomerular filtration rate (GFR) was not statistically different between the two groups, with P = 0.471, 0.429, and 0.847 at baseline, 3 and 6 months, respectively. The incidence of AKI, RRT, and BTT was not statistically different. Mortality was less in the inotrope group (P < 0.001). Conclusion Intravenous inotrope therapy in end-stage heart failure patients is non-inferior for mortality, incidence of AKI, need for RRT, and renal function for 6-month follow-up when compared to LVAD therapy. Further studies are needed to compare the effectiveness of inotropes versus LVAD implantation on renal function and outcomes over a longer time period. PMID:28611860

Influence of dialysis modality on plasma and tissue concentrations of pentosidine in patients with end-stage renal disease.

Plasma and tissue concentrations of pentose-derived glycation end-products ("pentosidine") are elevated in diabetic patients with normal renal function and in both diabetic and nondiabetic patients with end-stage renal disease. To determine the influence of dialysis modality and other clinical variables on the accumulation of pentosidine, we used high-performance liquid chromatography to measure this advanced glycation end-product in plasma, skin, and peritoneal samples obtained from 65 hemodialysis and 45 peritoneal dialysis patients. Plasma pentosidine levels were significantly lower in peritoneal dialysis patients. Concentrations of pentosidine in skin were similar in the two groups. In contrast, peritoneal concentrations of pentosidine were significantly higher in the patients maintained on peritoneal dialysis. Our results demonstrate that dialysis modality influences the plasma and tissue distribution of pentosidine. Compared with hemodialysis, peritoneal dialysis is associated with lower levels of this glycation end-product in plasma, but with higher levels in the peritoneum. The mechanisms accounting for lower circulating levels of pentosidine in peritoneal dialysis patients remain to be determined. Higher levels in peritoneal tissues may reflect chronic exposure to the high concentrations of glucose in peritoneal dialysate.

Novel Therapeutic Options for the Treatment of Mineral Metabolism Abnormalities in End Stage Renal Disease.

2015-01-01

Abnormalities in mineral metabolism are a universal complication in dialysis patients and are associated with an increased risk of cardiovascular disease and mortality. Hyperphosphatemia, increased fibroblast growth factor 23 levels and secondary hyperparathyroidism are all strongly associated with adverse outcomes in end stage renal disease (ESRD) and most treatment strategies target these parameters. Over the past few years, new therapies have emerged for the treatment of abnormalities of mineral metabolism in ESRD and many are promising. This article will review these new therapeutic options including the potential advantages and disadvantages compared to existing therapies. © 2015 Wiley Periodicals, Inc.

Exercise as an anabolic intervention in patients with end-stage renal disease.

PubMed

Ikizler, T Alp

2011-01-01

Muscle wasting and accompanying structural derangements leading to abnormalities in muscle function, exercise performance, and physical activity are common in patients with end-stage renal disease. Therefore, several studies have been performed examining the effects of exercise in this particular patient population. Most of the studies have assessed the effects of cardiopulmonary fitness training, whereas a few have examined the role of resistance (i.e., strength) training. Despite the proven efficacy of resistance exercise as an anabolic intervention in the otherwise healthy elderly population and certain chronic disease states, recent studies in patients on maintenance hemodialysis have not been encouraging in terms of long-term improvements in markers of muscle mass. Preliminary studies indicated that a combination of simultaneous exercise and nutritional supplementation could augment the anabolic effects of exercise, at least in the acute setting. However, a recent randomized clinical trial failed to show further benefits of additional resistance exercise on long-term somatic protein accretion above and beyond nutritional supplementation alone. Further research is necessary to both understand the observed lack of obvious benefits and strategies to improve the exercise regimens in patients with end-stage renal disease.

Chronic diseases have a great impact in the morbidity and mortality and in the health-related quality of life (HRQoL) of patients around the world. The impact of rheumatic diseases has not been fully recognized. We conducted a comparative study to evaluate the HRQoL in different chronic diseases. The aim of the present study was to assess the HRQoL and identify specific areas affected in patients with rheumatoid arthritis (RA), osteoarthritis (OA), diabetes mellitus, end-stage renal disease, geriatric subjects and a control group. We conducted a cross-sectional study, in a General Hospital in Morelia, Mexico. All patients met classification criteria for RA, OA, diabetes mellitus, end-stage renal disease; the geriatric subjects group was≥65 years, and the control group≥30 years. Demographic characteristics were recorded, different instruments were applied: SF-36, visual analogue scale for pain, patient's and physician's global assessments, Beck Depression Inventory and specific instruments (DAS-28, HAQ-Di, WOMAC, Diabetes Quality of Life [DQOL] and Kidney Disease Questionnaire of Life [KDQOL]). Biochemical measures: erythrocyte sedimentation rate, blood count, glucose, HbA1C, serum creatinine and urea. We evaluated 290 subjects (control group: 100; geriatric subjects: 30 and 160 for the rest of groups). Differences were detected in baseline characteristics (P<.0001). The SF-36 scores were different between control group and others groups (P=0.007). The worst HRQoL was in end-stage renal disease group (±SD: 48.06±18.84 x/SD). The general health was the principal affected area in RA. The pain was higher in rheumatic diseases: OA (5.2±2.4) and RA (5.1±3). HAQ was higher in OA compared to RA (1.12±0.76 vs 0.82±0.82, respectively; P=.001). Forty five percent of all subjects had depression. The HRQoL in RA patients is poor and comparable to other chronic diseases (end-stage renal disease and diabetes mellitus). Rheumatic diseases should be considered high impact diseases and therefore should receive more attention. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

To understand why treatment referral rates for ESRF are lower in Ireland than in other European countries, an investigation of factors influencing general practitioner referral of patients developing ESRF was conducted. Randomly selected general practitioners (N = 51) were interviewed using 32 standardised written patient scenarios to elicit referral strategies. General practitioner referral levels and thresholds for patients developing end-stage renal disease; referral routes (nephrologist vs other physicians); influence of patient age, marital status and co-morbidity on referral. Referral levels varied widely with the full range of cases (0-32; median = 15) referred by different doctors after consideration of first laboratory results. Less than half (44%) of cases were referred to a nephrologist. Patient age (40 vs 70 years), marital status, co-morbidity (none vs rheumatoid arthritis) and general practitioner prior specialist renal training (yes or no) did not influence referral rates. Many patients were not referred to a specialist at creatinine levels of 129 micromol/l (47% not referred) or 250 micromol/l (45%). While all patients were referred at higher levels (350 and 480 micromol/l), referral to a nephrologist decreased in likelihood as scenarios became more complex; 28% at 129 micromol/l creatinine; 28% at 250 micromol/l; 18% at 350 micromol/l and 14% at 480 micromol/l. Referral levels and routes were not influenced by general practitioner age, sex or practice location. Most general practitioners had little current contact with chronic renal patients (mean number in practice = 0.7, s.d. = 1.3). The very divergent management patterns identified highlight the need for guidance to general practitioners on appropriate management of this serious condition.

Survival of patients treated for end-stage renal disease by dialysis and transplantation.

1977-01-01

The results of treatment in 213 patients with end-stage renal disease who underwent hemodialysis, peritoneal dialysis or transplantation, or a combination, between 1962 and 1975 were analysed. Comparison by censored survival analysis showed significantly better (P less than 0.01) patient survival with the integrated therapy of dialysis and transplantation than with either form of dialysis alone. There was no significant difference in survival of males and females but survival at the extremes of age was poorer. Analysis of survival by major cause of renal failure indicated best survival in patients with congenital renal disease. Graft and patient survival rates at 1 year after the first transplantation were 42% and 69%. The major cause of death in this series was vascular disease but infection was responsible for 50% of deaths after transplantation. While integration of dialysis with transplantation produces best patient survival, this course is possible only when sufficient cadaver kidneys are available. PMID:334354

Limited data exist regarding the effect of fenestrated endovascular aneurysm repair (fEVAR) on renal function. We performed a comprehensive analysis of acute and chronic renal function changes in patients after fEVAR. This study included patients undergoing fEVAR at two institutions between September 2012 and March 2015. Glomerular filtration rate was estimated using the Modification of Diet in Renal Disease formula with serum creatinine levels obtained during the study period. Acute and chronic renal dysfunction was assessed using the RIFLE (Risk, Injury, Failure, Loss, End-stage renal disease) criteria and the chronic kidney disease (CKD) staging system, respectively. fEVAR was performed in 110 patients for juxtarenal or paravisceral aortic aneurysms, with a mean follow-up of 11.7 months. A total of 206 renal stents were placed, with a mean aneurysm size of 62.9 mm (range, 45-105 mm) and a mean neck length of 4.1 mm. Primary renal stent patency was 97.1% at the latest follow-up. Moderate kidney disease (CKD stage ≥ 3) was present in 51% of patients at baseline, with a mean preoperative glomerular filtration rate of 60.0 ± 19.6 mL/min/1.73 m 2 . Acute kidney injury occurred in 25 patients (22.7%), although 15 of these (60%) were classified as having mild dysfunction. During follow-up, 59 patients (73.7%) were found to have no change or improved renal disease by CKD staging, and 19 (23.7%) had a CKD increase of one stage. Two patients were noted to have end-stage renal failure requiring hemodialysis. Clinically significant renal dysfunction was noted in 21 patients (26.2%) at the latest follow-up. Freedom from renal decline at 1 year was 76.1% (95% confidence interval, 63.2%-85.0%). Surrogate markers for higher operative complexity, including operating time (P = .001), fluoroscopy time (P < .001), contrast volume (P = .017), and blood loss (P = .002), served as dependent risk factors for acute kidney injury, although though no independent predictors were identified. Age (P = .008) was an independent risk factor for long-term decline, whereas paradoxically, baseline kidney disease (P = .032) and longer operative times (P = .014) were protective of future renal dysfunction. Acute and chronic renal dysfunction both occur in approximately one-quarter of patients after fEVAR; however, most of these cases are classified as mild according to consensus definitions of renal injury. The presence of mild or moderate baseline kidney disease should not preclude endovascular repair in the juxtarenal population. Routine biochemical analysis and branch vessel surveillance remain important aspects of clinical follow-up for patients undergoing fEVAR. Copyright © 2016 Society for Vascular Surgery.

Serum levels of advanced glycation end products (AGEs) are markedly elevated in adults with chronic renal failure (CRF) and diabetes mellitus. Accumulation of AGEs in tissues contributes to the development of long-term complications. Up to now little has been known about the formation of AGEs in childhood. We determined serum levels of the well known AGEs pentosidine and Nvarepsilon-carboxymethyllysine (CML) in children with CRF (n=12), end-stage renal disease (ESRD) (n=9), renal transplantation (n=12), and type 1 diabetes mellitus (n=42) and in healthy children (n=20). Pentosidine was measured by high-performance liquid chromatography (HPLC), CML by a competitive enzyme-linked immunosorbent assay (ELISA) system. Serum levels of pentosidine and CML were significantly higher in the children with CRF and ESRD than in controls (P< 0.001), but nearly within the normal range after transplantation. Both AGEs showed a significant negative correlation with creatinine clearance (P< 0.001). During a single session of low-flux hemodialysis, total pentosidine and CML levels did not change. Free pentosidine, however, was reduced by 78% (P=0.04). Diabetic children showed significantly elevated pentosidine levels (P< 0.001) despite normal renal function. We conclude that, similar to adults, increased formation and accumulation of AGEs also exist in children with CRF and type 1 diabetes mellitus. At present the best prevention of AGE-related complications is an early renal transplantation in children with ESRD, as well as a careful metabolic monitoring of diabetics.

Primary hyperoxaluria (PH) is a rare genetic disorder characterized by overproduction of oxalate due to specific enzyme deficiencies in glyoxylate metabolism. The primary clinical presentation is in the form of recurrent urolithiasis, progressive nephrocalcinosis, end-stage renal disease, and systemic oxalosis. Herein, we present a case of PH who was diagnosed at 47 years of age after 6 years on hemodialysis. He presented with fatigue, anorexia, weight loss, and was found to have cachexia, diffuse edema, hepatomegaly, ascites, hypercalcemia, hyperphosphatemia, hypoalbuminemia, low parathyroid hormone levels, lytic and resorptive areas in the vertebrae, diffusely increased echogenity of the liver, multiple renal stones, and bilateral nephrocalcinosis. Bone marrow biopsy showed calcium oxalate crystals and crystal granulomas. The liver biopsy could not be performed. The absence of an identifiable reason for secondary forms, the severity of the clinical presentation, and pathological findings led to the diagnosis of PH2. He died while waiting for a potential liver and kidney donor. The presented case is consistent with the literature as he had renal stone disease in the third decade and end-stage renal disease in the fifth decade. Hypercalcemia was thought to be due to osteoclast-stimulating activity of macrophages constituting the granuloma. Erythropoietin-resistant anemia and hypothyroidism were thought to be due to accumulation of oxalate in the bone marrow and thyroid gland, respectively. It is very important to keep in mind the possibility of PH when faced with a patient with nephrocalcinosis and oxalate stone disease. © 2011 The Authors; Hemodialysis International © 2011 International Society for Hemodialysis.

Hyperoxaluria can cause not only nephrolithiasis and nephrocalcinosis, but also renal parenchymal disease histologically characterized by deposition of calcium oxalate crystals throughout the renal parenchyma, profound tubular damage and interstitial inflammation and fibrosis. Hyperoxaluric nephropathy presents clinically as acute or chronic renal failure that may progress to end-stage renal disease (ESRD). This sequence of events, well recognized in the past in primary and enteric hyperoxalurias, has also been documented in a few cases of dietary hyperoxaluria. Estimates of oxalate intake in patients with chronic dietary hyperoxaluria who developed chronic kidney disease or ESRD were comparable to the reported average oxalate content of the diets of certain populations worldwide, thus raising the question whether dietary hyperoxaluria is a primary cause of ESRD in these regions. Studies addressing this question have the potential of improving population health and should be undertaken, alongside ongoing studies which are yielding fresh insights into the mechanisms of intestinal absorption and renal excretion of oxalate, and into the mechanisms of development of oxalate-induced renal parenchymal disease. Novel preventive and therapeutic strategies for treating all types of hyperoxaluria are expected to develop from these studies. PMID:25374807

Remission of proteinuria and preservation of renal function in patients with renal AA amyloidosis secondary to rheumatoid arthritis.

Renal AA amyloidosis presents as a life-threatening disease in patients with rheumatoid arthritis (RA). Although several newly developed immunosuppressive drugs have been tried, patients often progress to end-stage renal failure with unsatisfactory survival rate. A total of nine consecutive cases of severe nephrotic renal AA amyloidosis presented to us. Complete remission of proteinuria was observed in four cases (responders), and the remaining five reached the end point of haemodialysis or death (non-responders); these groups were retrospectively compared. The patients were treated with immunosuppressants, biological drugs and anti-hypertensive drugs. Levels of serum creatinine (S-Cr), urinary protein-creatinine ratio (UP/UCr), blood pressure (BP) and C-reactive protein (CRP) were measured. Histological characteristics of renal amyloid deposition and extent of kidney injury were also scored. Prior to treatment, clinical data (S-Cr, UP/UCr, BP and CRP) and histological severity (glomerular sclerosis, tubulointerstitial injury and extent of amyloid deposition) observed in the renal biopsy specimen were not significantly different between the groups. Following therapeutic intervention, proteinuria disappeared (UP/UCr <0.3) in responders within 12 ± 5.4 months but persisted in non-responders. Consequently, renal function stabilized in responders, but it deteriorated in all non-responders. Strict inflammatory control along with optimal control of hypertension was achieved in responders during the treatment. Regardless of histological severity, intensive therapeutic intervention that includes strict inflammatory control and optimal control of hypertension may change the histology-predicted prognosis of RA-associated renal AA amyloidosis.

Relative to European Americans, evidence supports that African Americans with end-stage renal disease (ESRD) survive longer on dialysis. Renal-risk variants in the apolipoprotein L1 gene (APOL1), associated with non-diabetic nephropathy and less subclinical atherosclerosis, may contribute to dialysis outcomes. Here, APOL1 renal-risk variants were assessed for association with dialytic survival in 450 diabetic and 275 non-diabetic African American hemodialysis patients from Wake Forest and Emory School of Medicine outpatient facilities. Outcomes were provided by the ESRD Network 6-Southeastern Kidney Council Standardized Information Management System. Dates of death, receipt of a kidney transplant, and loss to follow-up were recorded. Outcomes were censored at the date of transplantation or through July 1, 2015. Multivariable Cox proportional hazards models were computed separately in patients with non-diabetic and diabetic ESRD, adjusting for the covariates age, gender, comorbidities, ancestry, and presence of an arteriovenous fistula or graft at dialysis initiation. In non-diabetic ESRD, patients with two (vs. zero/one) APOL1 renal-risk variants had significantly longer dialysis survival (hazard ratio 0.57); a pattern not observed in patients with diabetes-associated ESRD (hazard ratio 1.29). Thus, two APOL1 renal-risk variants are associated with longer dialysis survival in African Americans without diabetes, potentially relating to presence of renal-limited disease or less atherosclerosis.

There are complex risk-benefit tradeoffs with different transplantation strategies for end-stage liver disease patients on renal support. Using a Markov discrete-time state transition model, we compared survival for this group with 3 strategies: simultaneous liver-kidney (SLK) transplantation, liver transplantation alone (LTA) followed by immediate kidney transplantation if renal function did not recover, and LTA followed by placement on the kidney transplant wait list. Patients were followed for 30 years from the age of 50 years. The probabilities of events were synthesized from population data and clinical trials according to Model for End-Stage Liver Disease (MELD) scores (21-30 and >30) to estimate input parameters. Sensitivity analyses tested the impact of uncertainty on survival. Overall, the highest survival rates were seen with SLK transplantation for both MELD score groups (82.8% for MELD scores of 21-30 and 82.5% for MELD scores > 30 at 1 year), albeit at the cost of using kidneys that might not be needed. Liver transplantation followed by kidney transplantation led to higher survival rates (77.3% and 76.4%, respectively, at 1 year) than placement on the kidney transplant wait list (75.1% and 74.3%, respectively, at 1 year). When uncertainty was considered, the results indicated that the waiting time and renal recovery affected conclusions about survival after SLK transplantation and liver transplantation, respectively. The subgroups with the longest durations of pretransplant renal replacement therapy and highest MELD scores had the largest absolute increases in survival with SLK transplantation versus sequential transplantation. In conclusion, the findings demonstrate the inherent tension in choices about the use of available kidneys and suggest that performing liver transplantation and using renal transplantation only for those who fail to recover their native renal function could free up available donor kidneys. These results could inform discussions about transplantation policy. © 2014 American Association for the Study of Liver Diseases.

Chronic kidney disease (CKD) is a major healthcare problem with increasing prevalence in the population. CKD leads to end stage renal disease and increases the risk of cardiovascular disease. As such, it is important to study the mechanisms underlying CKD progression. To this end, an animal model was developed to allow the testing of new treatment strategies or molecular targets for CKD prevention. Many underlying risk factors result in CKD but the disease itself has common features, including renal interstitial fibrosis, tubular epithelial cell loss through apoptosis, glomerular damage, and renal inflammation. Further, CKD shows differences in prevalence between the genders with premenopausal women being relatively resistant to CKD. We sought to develop and characterize an animal model with these common features of human CKD in the C57BL/6 mouse. Mice of this genetic background have been used to produce transgenic strains that are commercially available. Thus, a CKD model in this strain would allow the testing of the effects of numerous genes on the severity or progression of CKD with minimal cost. This paper describes such a mouse model of CKD utilizing angiotensin II and deoxycorticosterone acetate as inducers. PMID:26064882

Cardiovascular disease is a major cause of morbidity and mortality in young adults with end-stage renal disease (ESRD), but its basis is still not well understood. We therefore evaluated the determinants of atherosclerosis in children with ESRD. A total of 37 children with ESRD (with 31 who had undergone transplantation) were examined and compared to a control group comprising 22 healthy children. The common carotid intima-media thickness (CIMT) was measured by ultrasound as a marker of preclinical atherosclerosis. The association of CIMT with anthropometrical data, blood pressure, plasma lipid levels, and other biochemical parameters potentially related to cardiovascular disease was evaluated. Children with ESRD had significantly higher CIMT, blood pressure, and levels of lipoprotein (a), urea, creatinine, ferritin, homocysteine, and serum uric acid as well as significantly lower values of apolipoprotein A. The atherogenic index of plasma (log(triglycerides/HDL cholesterol)) was also higher in patients with ESRD; however, this difference reached only borderline significance. In addition, a negative correlation was found between CIMT and serum albumin and bilirubin in the ESRD group, and this correlation was independent of age and body mass index. In the control group, a significant positive correlation was observed between CIMT and ferritin levels. Factors other than traditional cardiovascular properties, such as the anti-oxidative capacity of circulating blood, may be of importance during the early stages of atherosclerosis in children with end-stage renal disease.

Diabetic nephropathy is a major cause of end-stage renal disease in developed countries. While angiotensin-converting enzyme (ACE) inhibitors are used to treat diabetic nephropathy, how intrarenal ACE contributes to diabetic renal injury is uncertain. Here, two mouse models with different patterns of renal ACE expression were studied to determine the specific contribution of tubular vs. glomerular ACE to early diabetic nephropathy: it-ACE mice, which make endothelial ACE but lack ACE expression by renal tubular epithelium, and ACE 3/9 mice, which lack endothelial ACE and only express renal ACE in tubular epithelial cells. The absence of endothelial ACE normalized the glomerular filtration rate and endothelial injury in diabetic ACE 3/9 mice. However, these mice developed tubular injury and albuminuria and displayed low renal levels of megalin that were similar to those observed in diabetic wild-type mice. In diabetic it-ACE mice, despite hyperfiltration, the absence of renal tubular ACE greatly reduced tubulointerstitial injury and albuminuria and increased renal megalin expression compared with diabetic wild-type and diabetic ACE 3/9 mice. These findings demonstrate that endothelial ACE is a central regulator of the glomerular filtration rate while tubular ACE is a key player in the development of tubular injury and albuminuria. These data suggest that tubular injury, rather than hyperfiltration, is the main cause of microalbuminuria in early diabetic nephropathy.

Disease management improves end-stage renal disease outcomes.

Sands, Jeffrey J

2006-01-01

Renal disease management organizations have reported achieving significant decreases in mortality and hospitalization in conjunction with cost savings, improved patient satisfaction and quality of life. Disease management organizations strive to fill existing gaps in care delivery through the standardized use of risk assessment, predictive modeling, evidence-based guidelines, and process and outcomes measurement. Patient self-management education and the provision of individual nurse care managers are also key program components. As we more fully measure clinical outcomes and total healthcare costs, including payments from all insurance and government entities, pharmacy costs and out of pocket expenditures, the full implications of disease management can be better defined. The results of this analysis will have a profound influence on United States healthcare policy. At present current data suggest that the promise of disease management, improved care at reduced cost, can and is being realized in end-stage renal disease. Copyright 2006 S. Karger AG, Basel.

We report a 66-year-old Japanese male with end-stage renal disease (ESRD) and advanced non-small cell lung cancer (NSCLC) who was on hemodialysis. The patient harbored high programmed death ligand 1 (PD-L1) expression and was successfully treated with pembrolizumab. Laboratory examination upon diagnosis showed elevated serum creatinine (6.58 mg/dL). We administered pembrolizumab (200 mg/body) and repeated every 3 weeks. His renal dysfunction gradually progressed, hemodialysis was initiated after eight courses of pembrolizumab, and the antitumor effect was maintained at five months after hemodialysis initiation. Therefore, pembrolizumab can be administered for patients with ESRD and advanced NSCLC, who harbor high PD-L1 expression, during preparation for hemodialysis.

Total artificial heart (TAH) device is sometimes necessary to treat end stage heart failure (HF). After surgery, renal impairment can occur with the need of renal replacement therapy. We report the case of a 51-year-old man who was treated with conventional hemodialysis (HD) while on support with TAH. The patient underwent HD while on TAH support during 14 months. He benefited from conventional HD, 6 sessions per week. HD sessions were well tolerated, and patient's condition and quality of life improved significantly. The main difficulty was to maintain red blood cell level because of chronic hemolysis due to TAH, which required repetitive blood transfusions, resulting in a high rate of human leukocyte antigen sensitization. Unfortunately, the patient died of mesenteric ischemia due to anticoagulation under dosing. We conclude that HD treatment is possible despite TAH and should be considered in patients with both end stage renal and HF. © 2016 S. Karger AG, Basel.

History of peritoneal dialysis in Latin America.

PubMed

Riella, Miguel C; Locatelli, Alberto J

2007-01-01

Latin America is a region formed by a number of countries of Latin heritage in which the common languages spoken are Spanish and Portuguese. Latin America was not isolated from the evolution of peritoneal dialysis (PD) throughout the rest of the world, as evidenced by the fact that, between the 1940s and the 1960s, PD was used to treat acute renal failure patients and later for the intermittent treatment of end-stage renal failure patients. The true development of PD took place toward the end of the 1970s and beginning of the 1980s with the introduction of continuous ambulatory peritoneal dialysis (CAPD). It is evident that the introduction of CAPD in most countries was a result of the personal effort and interest of individuals or groups of nephrologists. Initially, PD was not always implemented under ideal circumstances; locally manufactured, improvised supplies were associated with poor results. The arrival of companies with appropriate equipment and supplies led to widespread dissemination of this new modality. Furthermore, regulations and reimbursement by health authorities were additional obstacles. It is clear that PD in Latin America is still largely utilized to treat acute renal failure patients, particularly in countries where hemodialysis is not readily available. It is still employed intermittently to manage end-stage renal failure patients when hemodialysis is not available. With the exception of Colombia and Mexico, CAPD penetration is below 10%. While CAPD is nonexistent in certain countries, such as Cuba, due to lack of supplies, in other countries, such as Chile, it is restricted to patients that cannot be placed or continued on hemodialysis, those for example who lack vascular access, or those from remote rural areas. In addition, automated PD is relatively more costly and is therefore restricted in some countries.

Pseudo-hemothorax at computed tomography due to residual contrast media.

Pleural effusion is a clinical problem that has many causes, with hemothorax being one of them. Computed tomography readily characterizes pleural fluid with determination of the attenuation value, helping to distinguish hemothorax from other types of effusion. Herein, we report the case of a 67-year-old man with end-stage renal disease in which a high-density pleural effusion due to residual contrast media was misinterpreted as hemothorax. Radiologists should consider the possibility of contrast media retention when interpreting a high-density pleural effusion in patients with end-stage renal disease. Recognition of this entity is crucial to avoid misdiagnosis, which might lead to unnecessary testing or procedures. Copyright © 2014 Elsevier Inc. All rights reserved.

Examining international differences in health outcomes for end-stage renal disease (ESRD) patients requires an understanding of ESRD funding structures. In Canada, funding for all aspects of dialysis and transplant care, with the exception of drugs (for which supplementary insurance can be purchased), is provided for all citizens. Although ESRD programs across Canada's 10 provinces differ in funding structure, they share important economic characteristics, including being publicly funded and universal, and providing most facets of ESRD care for free. This paper explains how ESRD care fits into the Canadian health care system, describes the epidemiology of ESRD in Canada, and offers economic explanations for international discrepancies.

Chronic kidney disease-associated pruritus (CKD-aP) is a distressing, often overlooked condition in patients with CKD and end-stage renal disease. It affects ~40% of patients with end-stage renal disease and has been associated with poor quality of life, poor sleep, depression, and mortality. Prevalence estimates vary based on the instruments used to diagnose CKD-aP, and standardized diagnostic instruments are sorely needed. Treatment studies have often yielded conflicting results. This is likely related to studies that are limited by small sample size, flawed designs, and nonstandardized diagnostic instruments. Several large well-designed treatment trials have recently been completed and may soon influence CKD-aP management. PMID:28176969

Diabetic nephropathy is a severe complication of type 1 diabetes (T1D) that may lead to renal failure and end-stage renal disease (ESRD) demanding dialysis and transplantation. The etiology of diabetic nephropathy is multifactorial and both genes and environmental and life style-related factors are involved. In this study, we investigate the effect of the socioeconomic exposures, unemployment and receiving income support, on the development of ESRD in T1D patients, using a marginal structural model (MSM) in comparison with standard logistic regression models. The study is based on the Swedish Childhood Diabetes Register which in 1977 started to register patients developing T1D before 15 years of age. In the analyses, we include patients born between 1965 and 1979, developing diabetes between 1977 and 1994, and followed until 2013 (n = 4034). A MSM was fitted to adjust for both baseline and time-varying confounders. The main results of the analysis indicate that being unemployed for more than 1 year and receiving income support are risk factors for the development of ESRD. Multiple exposures over time to these risk factors increase the risk associated with the disease. Using a MSM is an advanced method well suited to investigate the effect of exposures on the risk of complications of a chronic disease with longitudinal data. The results show that socioeconomic disadvantage increases the risk of developing ESRD in patients with T1D. Copyright © 2017 Elsevier Inc. All rights reserved.

The overall risk of some cancers is increased in patients receiving regular dialysis treatment due to chronic oxidative stress, a weakened immune system and enhanced genomic damage. These patients could benefit from the same antineoplastic treatment delivered to patients with normal renal function, but a better risk/benefit ratio could be achieved by establishing specific guidelines. Key considerations are which chemotherapeutic agent to use, adjustment of dosages and timing of dialysis in relation to the administration of chemotherapy. We have reviewed available data present in the literature, including recommendations and expert opinions on cancer risk and use of chemotherapeutic agents in patients with end-stage renal disease. Experts selected by the boards of the societies provided additional information which helped greatly in clarifying some issues on which clear-cut information was missing or available data were conflicting. Data on the optimal use of chemotherapeutic agents or on credible schemes of polychemotherapy in haemodialysed patients are sparse and mainly derive from case reports or small case series. However, recommendations on dosing and timing of dialysis can be proposed for the most prescribed chemotherapeutic agents. The use of chemotherapeutic agents as single agents, or in combination, can be safely given in patients with end-stage renal disease. Appropriate dosage adjustments should be considered based on drug dialysability and pharmacokinetics. Coordinated care between oncologists, nephrologists and pharmacists is of pivotal importance to optimise drug delivery and timing of dialysis.

Combined heart and kidney transplant has become an accepted therapy for patients with coexisting heart and kidney failure. This method, compared with single-organ transplant, has a better outcome. Here, we report the first successful combined heart and kidney transplant in Iran. The patient was a 36-year-old man with end-stage renal disease owing to IgA nephropathy, admitted to Masih Daneshvari Hospital in Tehran, Iran for progressive dyspnea and chest pain. In-patient evaluations revealed cardiomyopathy leading to end-stage heart failure. Owing to concurrent heart and kidney end-stage diseases, combined cardiorenal transplant was done. Eight months after his transplant, routine follow-ups have not shown any signs of acute rejection. He is now New York Heart Association functional class I. Both cardiac and renal functions are within normal ranges. Good outcome during follow-up for this case justifies simultaneous heart plus kidney transplants as an alternate treatment for patients with advanced disease of both organs.

Kidney transplant and liver transplant are the treatments of choice for patients with end-stage renal disease and end-stage liver disease, respectively. Pancreas transplant is most commonly performed along with kidney transplant in diabetic end-stage renal disease patients. Despite a steady increase in the numbers of kidney and liver transplants performed each year in the United States, a significant shortage of kidneys and livers available for transplant remains. Organ allocation is the process the Organ Procurement and Transplantation Network (OPTN) uses to determine which candidates are offered which deceased donor organs. OPTN is charged with ensuring the effectiveness, efficiency and equity of organ sharing in the national system of organ allocation. The policy has changed incrementally over time in efforts to optimize allocation to meet these often competing goals. This review describes the history, current status and future direction of policies regarding the allocation of abdominal organs for transplant, namely the kidney, liver and pancreas, in the United States.

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 < 2 years and highest in those aged 6-12 years, and with no documented review of site care or an exit site score  of > 0 at prior month's visit (p < 0.001). Gender, race, end stage renal disease etiology, exit site orientation, catheter cuff number or mobilization, and presence of G-tube, stoma, or vesicostomy were unassociated with ESI incidence. Of the ESIs reported, 71% resolved with 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.

To assess for the presence of a sex interaction in the associations of estimated glomerular filtration rate and albuminuria with all-cause mortality, cardiovascular mortality, and end stage renal disease. Random effects meta-analysis using pooled individual participant data. 46 cohorts from Europe, North and South America, Asia, and Australasia. 2,051,158 participants (54% women) from general population cohorts (n=1,861,052), high risk cohorts (n=151,494), and chronic kidney disease cohorts (n=38,612). Eligible cohorts (except chronic kidney disease cohorts) had at least 1000 participants, outcomes of either mortality or end stage renal disease of ≥ 50 events, and baseline measurements of estimated glomerular filtration rate according to the Chronic Kidney Disease Epidemiology Collaboration equation (mL/min/1.73 m(2)) and urinary albumin-creatinine ratio (mg/g). Risks of all-cause mortality and cardiovascular mortality were higher in men at all levels of estimated glomerular filtration rate and albumin-creatinine ratio. While higher risk was associated with lower estimated glomerular filtration rate and higher albumin-creatinine ratio in both sexes, the slope of the risk relationship for all-cause mortality and for cardiovascular mortality were steeper in women than in men. Compared with an estimated glomerular filtration rate of 95, the adjusted hazard ratio for all-cause mortality at estimated glomerular filtration rate 45 was 1.32 (95% CI 1.08 to 1.61) in women and 1.22 (1.00 to 1.48) in men (P(interaction)<0.01). Compared with a urinary albumin-creatinine ratio of 5, the adjusted hazard ratio for all-cause mortality at urinary albumin-creatinine ratio 30 was 1.69 (1.54 to 1.84) in women and 1.43 (1.31 to 1.57) in men (P(interaction)<0.01). Conversely, there was no evidence of a sex difference in associations of estimated glomerular filtration rate and urinary albumin-creatinine ratio with end stage renal disease risk. Both sexes face increased risk of all-cause mortality, cardiovascular mortality, and end stage renal disease with lower estimated glomerular filtration rates and higher albuminuria. These findings were robust across a large global consortium.

Apparent treatment-resistant hypertension (aTRH) is defined as uncontrolled hypertension despite the use of ≥3 antihypertensive medication classes or controlled hypertension while treated with ≥4 antihypertensive medication classes. Although a high prevalence of aTRH has been reported, few data are available on its association with cardiovascular and renal outcomes. We analyzed data on 14 684 Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) participants to determine the association between aTRH (n=1870) with coronary heart disease, stroke, all-cause mortality, heart failure, peripheral artery disease, and end-stage renal disease. We defined aTRH as blood pressure not at goal (systolic/diastolic blood pressure ≥140/90 mm Hg) while taking ≥3 classes of antihypertensive medication or taking ≥4 classes of antihypertensive medication with blood pressure at goal during the year 2 ALLHAT study visit (1996-2000). Use of a diuretic was not required to meet the definition of aTRH. Follow-up occurred through 2002. The multivariable adjusted hazard ratios (95% confidence intervals) comparing participants with versus without aTRH were as follows: coronary heart disease (1.44 [1.18-1.76]), stroke (1.57 [1.18-2.08]), all-cause mortality (1.30 [1.11-1.52]), heart failure (1.88 [1.52-2.34]), peripheral artery disease (1.23 [0.85-1.79]), and end-stage renal disease (1.95 [1.11-3.41]). aTRH was also associated with the pooled outcomes of combined coronary heart disease (hazard ratio, 1.47; 95% confidence interval, 1.26-1.71) and combined cardiovascular disease (hazard ratio, 1.46; 95% confidence interval, 1.29-1.64). These results demonstrate that aTRH increases the risk for cardiovascular disease and end-stage renal disease. Studies are needed to identify approaches to prevent aTRH and reduce risk for adverse outcomes among individuals with aTRH. © 2014 American Heart Association, Inc.

Familial Mediterranean fever (FMF, OMIM 249100) is the most common hereditary fever, resulting from mutations in MEFV. FMF is characterized by episodic febrile attacks and polyserositis. Renal AA-amyloidosis is a major complication, which often leads to end-stage renal disease in untreated patients. The data about the renal AA-amyloidosis secondary to FMF are scarce in North African countries and non-existent in Algeria. We aimed to investigate the MEFV mutations associated with this complication in an Algerian patient cohort. Molecular analysis included 28 unrelated Algerian FMF patients with ascertained amyloidosis, 23 of them were symptomatic and 5 were asymptomatic. For this study, a group of 20 FMF patients without renal amyloidosis were selected as controls according to their age, disease onset and disease duration. The mutations were detected by sequencing exon 10 of MEFV. A total of 87.5% (49/56) mutant alleles were identified in 27/28 analyzed patients; p.M694I was predominant and appeared with an allele frequency of 62.5%, followed by p.M694V (17.85%), p.M680I (5.35%) and p.I692Del (1.78%). Remarkably, only p.M694I mutation was observed among the asymptomatic patients. The M694I/M694I genotype, identified in 14/27 (52%) patients, was significantly associated with the development of amyloidosis compared to group of controls (p = 0.022). This study did not link the M694V/M694V genotype to the renal complication despite the fact that it has been observed only in the patients with amyloidosis (3/27; 11%) (p = 0.349). The association of other identified genotypes to this complication was statistically insignificant. The progression of amyloidosis led to end-stage renal disease in 14 patients with 6 deaths. This study shows that p.M694I homozygosity is a potential genetic risk factor for the development of renal AA-amyloidosis in Algerian FMF patients. Copyright © 2016 Elsevier Masson SAS.

A novel equation, the Chronic Kidney Disease Epidemiology Collaboration, has been proposed to replace the Modification of Diet in Renal Disease for estimated glomerular filtration rate due to higher accuracy, particularly in the setting of normal renal function. We compared these equations in patients with 2 functioning kidneys undergoing partial nephrectomy. We assembled a cohort of 1,158 patients from 5 institutions who underwent partial nephrectomy between 1991 and 2009. Only subjects with 2 functioning kidneys were included in the study. The end points were baseline estimated glomerular filtration rate, last followup estimated glomerular filtration rate (3 to 18 months), absolute and percent change estimated glomerular filtration rate ([absolute change/baseline] × 100%), and proportion of newly developed chronic kidney disease stage III. The agreement between the equations was evaluated using Bland-Altman plots and the McNemar test for paired observations. Mean baseline estimated glomerular filtration rate derived from the Modification of Diet in Renal Disease and Chronic Kidney Disease Epidemiology Collaboration equations were 73 and 77 ml/minute/1.73 m(2), respectively, and following surgery were 63 and 67 ml/minute/1.73 m(2), respectively. Mean percent change estimated glomerular filtration rate was -12% for both equations (p = 0.2). The proportion of patients with newly developed chronic kidney disease stage III following surgery was 32% and 25%, according to the Modification of Diet in Renal Disease and Chronic Kidney Disease Epidemiology Collaboration equations, respectively (p = 0.001). For patients with 2 functioning kidneys undergoing partial nephrectomy the Chronic Kidney Disease Epidemiology Collaboration equation provides slightly higher glomerular filtration rate estimates compared to the Modification of Diet in Renal Disease equation, with 7% fewer patients categorized as having chronic kidney disease stage III or worse.

Patients with end-stage renal disease (ESRD) and on hemodialysis (HD) are at increased risk for developing rheumatoid arthritis (RA), as a result of defective immunity. Our aim was to examine if ESRD and the length of HD treatment impact the clinical utility of antibodies to cyclic citrullinated peptides (anti-CCP) and rheumatoid factor (RF) as diagnostic tools for RA. We included 94 subjects in our study: 37 healthy volunteers and 57 patients with ESRD who had been undergoing HD for 1-12 years, and without confirmed RA. In order to test our hypothesis, we measured and correlated anti-CCP and RF as laboratory markers of RA. Our study showed that there is no significant difference between values for anti-CCP (p=0.11) and RF (p=0.98) in control subjects as well as in patients undergoing HD, regardless of the length of time that patients had been undergoing HD treatment. Our study indicates that HD does not impair the specificity of anti-CCP and RF for RA in patients where the disease has not yet developed. Future prospective studies may show whether there is any use in determinating RF, and especially anti-CCP, as early predictors of RA in patients with ESRD who are at greater risk of developing this condition.

Protease activated receptor 2 in diabetic nephropathy: a double edged sword

Diabetic nephropathy is a major microvascular complication of diabetes mellitus, and the leading cause of end stage renal disease worldwide. The pathogenesis of diabetic nephropathy is complex, making the development of novel treatments that stop or reverse the progression of microalbuminuria into end stage renal disease a challenge. Protease activated receptor (PAR)-2 has recently been shown to aggravate disease progression in diabetic nephropathy based upon which it was suggested that PAR-2 would be a potential target for the treatment of diabetic nephropathy. To fully appreciate the translational potential of PAR-2 in diabetic nephropathy, we evaluated the effect of PAR-2 deficiency on the development of diabetic nephropathy in a streptozotocin-induced diabetes model characteristic of type 1 diabetes. Although diabetic PAR-2 deficient mice showed reduced albuminuria compared to diabetic wild type mice, an increase in mesangial expansion was evident in the PAR-2 deficient mice. No differences were observed in blood glucose levels, podocyte numbers or in glomerular vascular density. These results show that PAR-2 plays a dual role in the development of streptozotocin-induced diabetic nephropathy and may thus not be the eagerly awaited novel target to combat diabetic nephropathy. Targeting PAR-2 should consequently only be pursued with great care in a clinical setting. PMID:29118913

Self-management of type 1 diabetes over a lifetime is complex and challenging even in the best of circumstances, and the social environment can be a powerful determinant of health behaviours and outcomes. The aim of this study was to identify how social determinants of health can impact on the capacity of young people to manage their glycaemic control. The findings emerged from a constructivist grounded theory approach through an in-depth examination of life course events that were recounted through qualitative interviews. The rich descriptive detail obtained from this enquiry locates common experiences and the context in which concordance with therapies occurs and health behaviours develop. This qualitative study of young people with type 1 diabetes who have developed end-stage renal disease demonstrates that there are many factors beyond individual control that can contribute to health outcomes. The social determinants of childhood environment, education, socio-economic status, gender and the culture of public health can contribute to disengagement from treatment regimens and the health-care system and to the development of microvascular complications at a comparatively young age. These findings challenge the assumptions of health-care practitioners about individual responsibility and highlight the importance of considering how social determinants can shape lives, behaviours and health. © 2014 John Wiley & Sons Ltd.

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.

Racial and ethnic disparities in end-stage kidney failure-survival paradoxes in African-Americans.

PubMed

Agodoa, Lawrence; Eggers, Paul

2007-01-01

The risk of death is nearly 45% lower in African-Americans than Caucasians undergoing chronic hemodialysis. In light of the higher mortality rate in African-Americans in the general US population, this paradox requires explanation and further investigation. Factors that may contribute to this survival advantage include a younger age at which African-Americans arrive at end-stage renal disease (ESRD) and the slightly higher body mass index. On the other hand, factors, such as lower residual renal function, lower mean hemoglobin and hematocrit, increased prevalence of hypertension, a higher prevalence of catheter use for initial dialysis, and generally lower dose of dialysis should put African-Americans on dialysis at a higher risk of death. This survival advantage seems to be completely annulled with a successful renal transplant. Finally, it should be noted that ESRD carries with it a very high mortality rate in all racial and ethnic groups. A successful renal transplant improves but does not restore the expected remaining life times. Therefore, aggressive approach is required in investigating the factors that confer such high mortality risk on ESRD patients.

Relative to European Americans, evidence supports that African Americans with end-stage renal disease (ESRD) survive longer on dialysis. Renal-risk variants in the apolipoprotein L1 gene (APOL1), associated with nondiabetic nephropathy and less subclinical atherosclerosis, may contribute to dialysis outcomes. Here, APOL1 renal-risk variants were assessed for association with dialytic survival in 450 diabetic and 275 nondiabetic African American hemodialysis patients from Wake Forest and Emory School of Medicine outpatient facilities. Outcomes were provided by the ESRD Network 6-Southeastern Kidney Council Standardized Information Management System. Dates of death, receipt of a kidney transplant, and loss to follow-up were recorded. Outcomes were censored at the date of transplantation or through 1 July 2015. Multivariable Cox proportional hazards models were computed separately in patients with nondiabetic and diabetic ESRD, adjusting for the covariates age, gender, comorbidities, ancestry, and presence of an arteriovenous fistula or graft at dialysis initiation. In nondiabetic ESRD, patients with 2 (vs. 0/1) APOL1 renal-risk variants had significantly longer dialysis survival (hazard ratio 0.57), a pattern not observed in patients with diabetes-associated ESRD (hazard ratio 1.29). Thus, 2 APOL1 renal-risk variants are associated with longer dialysis survival in African Americans without diabetes, potentially relating to presence of renal-limited disease or less atherosclerosis.

The autonomic nervous system plays an important role in heart function regulation. One of the most acknowledged methods for noninvasive measurement of autonomic system activity is to determine heart rate variability (HRV). Reduced HRV parameters-heart rate rigidity/stiffness-are an independent prognostic factor of sudden cardiac death risk because of arrhythmia. Renal transplantation is an important factor in HRV changes because of hemodynamic and ion disturbances. The main purpose of this study was to determine the influence of HRV disturbances during renal transplantation procedures on long-term mortality in patients with chronic kidney disease. A prospective observation study was performed in the Department of Anesthesiology, Intensive Care, and Acute Poisoning, Pomeranian Medical University, Szczecin, Poland. There were 75 patients (mean age, 47 ± 12 years; 42 men) treated with renal transplantation between 2008 and 2010. Patients were monitored with electrocardiographic tracing with the use of 7 electrodes in position type B. The final stage of analysis was to determine the possible relationship between HRV parameters during the perioperative period and the number of deaths within a 5-year follow-up. HRV parameters during the perioperative period of renal transplantation and the number of deaths within a 5-year follow-up, measured by use of the Holter method, did not differ among patients in the studied population. HRV is a noninvasive and confirmed tool used for the evaluation of autonomic function and mortality risk in patients with end-stage renal disease. HRV parameters recorded in the perioperative period are not optimal stratification tools for estimating the risk of cardiac deaths in patients with end-stage renal disease.

Bartter syndrome (BS) is a clinically and genetically heterogeneous inherited renal tube disorder characterized by renal salt wasting, hypokalemic metabolic alkalosis and normotensive hyperreninemic hyperaldosteronism. There have been several case reports of BS complicated by focal segmental glomerulosclerosis (FSGS). Here, we have reported the case of a BS patient who developed FSGS and subsequent end-stage renal disease (ESRD) and provided a brief literature review. The patient presented with classic BS at 3 months of age and developed proteinuria at 7 years. Renal biopsy performed at 11 years of age revealed a FSGS perihilar variant. Hemodialysis was initiated at 11 years of age, and kidney transplantation was performed at 16 years of age. The post-transplantation course has been uneventful for more than 3 years with complete disappearance of BS without the recurrence of FSGS. Genetic study revealed a homozygous p.Trp(TGG)610Stop(TGA) mutation in the CLCNKB gene. In summary, BS may be complicated by secondary FSGS due to the adaptive response to chronic salt-losing nephropathy, and FSGS may progress to ESRD in some patients. Renal transplantation in patients with BS and ESRD results in complete remission of BS. PMID:21359059

Common Drugs for Stabilization of Renal Function in the Progression of Diabetic Nephropathy and Their Relations with Hypertension Therapy.

2018-01-01

Diabetic nephropathy is characterized by hypertension, progressive albuminuria, glomerulosclerosis and declines in glomerular filtration rate leading to end stage renal disease. Although the pathogenesis of diabetic nephropathy is not fully understood, current treatment of the patients with diabetic nephropathy is mainly based upon the control of hyperglycaemia and management of blood pressures. Several drugs, which are originally developed for hypertension therapy, have been adopted for stabilization of renal function in diabetic nephropathy. In this review, we first discussed the relationships between diabetic nephropathy and hypertension particularly in the renin-angiotensinaldosterone system. We then summarized chemical structures, pharmacological characteristics and clinical studies of the common drugs used for treatment of diabetic nephropathy, while these drugs have effects against hypertension. This review may provide the constructive information for further drug development in diabetic nephropathy.

Myelomeningocele (MMC) results from a failure of normal neural tube fusion in early fetal development. Retrospective, observational study of medical data of 54 children treated in Pediatric Nephrology and Urology Clinics for five years was performed. The following data were analyzed: serum creatinine, eGFR, urine analysis, renal scintigraphy (RS), renal ultrasound, and urodynamics. Mean age of studied population: 12.3 years, median of eGFR at the beginning and at the end of survey was 110.25 and 116.5 mL/min/1.73 m2 accordingly. Median of frequency of urinary tract infections (fUTI): 1.2 episodes/year. In 24 children: low-pressure, in 30 children: high-pressure bladder was noted. Vesicouretral reflux (VUR) was noted in 23 children (42.6%). fUTI were more common in high-grade VUR group. High-grade VURs were more common in group of patients with severe renal damage. At the end of the survey 11.1% children were qualified to higher stages of chronic kidney disease. Renal parenchyma damage progression in RS was noted in 22.2% children. Positive VUR history, febrile recurrent UTIs, bladder wall trabeculation, and older age of the patients constitute risk factors of abnormal renal scans. More than 2.0 febrile, symptomatic UTIs annually increase by 5.6-fold the risk of severe renal parenchyma damage after five years. PMID:27598183

Pesticide exposure has been found to cause renal damage and dysfunction in experimental studies, but epidemiological research on the renal effects of chronic low-level pesticide exposure is limited. We investigated the relationships between end-stage renal disease (ESRD) among wives of licensed pesticide applicators (N=31,142) in the Agricultural Health Study (AHS) and (1) personal pesticide use, (2) exposure to the husband's pesticide use, and (3) other pesticide-associated farming and household activities. AHS participants reported pesticide exposure via self-administered questionnaires at enrollment (1993-1997). ESRD cases were identified via linkage to the United States Renal Data System. Associations between ESRD and pesticide exposures were estimated with Cox proportional hazard regression models controlling for age at enrollment. Models of associations with farming and household factors were additionally adjusted for personal use of pesticides. We identified 98 ESRD cases diagnosed between enrollment and 31 December 2011. Although women who ever applied pesticides (56% of cohort) were less likely than those who did not apply to develop ESRD (Hazard Ratio (HR): 0.42; 95% CI: 0.28, 0.64), among women who did apply pesticides, the rate of ESRD was significantly elevated among those who reported the highest (vs. lowest) cumulative general pesticide use (HR: 4.22; 95% CI: 1.26, 14.20). Among wives who never applied pesticides, ESRD was associated with husbands' ever use of paraquat (HR=1.99; 95% CI: 1.14, 3.47) and butylate (HR=1.71; 95% CI: 1.00, 2.95), with a positive exposure-response pattern for husband's cumulative use of these pesticides. ESRD may be associated with direct and/or indirect exposure to pesticides among farm women. Future studies should evaluate indirect exposure risk among other rural populations.

Patients with chronic renal failure (CRF) may require total joint arthroplasty (TJA) to treat degenerative joint disease, fractures, osteonecrosis, or amyloid arthropathy. There have been conflicting results, however, regarding outcomes of TJA in patients with chronic renal disease. The aim of this case-controlled study was to determine the outcome of TJA in patients with CRF, with particular interest in the incidence of infections and inhospital mortality. We queried our electronic database to determine which patients among the 29,389 TJAs performed at our institution between January 2000 and June 2012 had a diagnosis of CRF. A total of 359 CRF patients were identified and matched for procedure, gender, age (±4 years), date of surgery (±2 years), and body mass index (±5 kg/m 2 ) in a 2:1 ratio to 718 control patients. The incidence of infection and inhospital mortality was not significantly different between the nondialysis CRF patients and controls, whereas it was significantly higher in dialysis-dependent end-stage renal failure patients compared to controls. Of the 50 CRF patients receiving hemodialysis, 10 (20%) developed surgical site infection, of which 4 (8%) were periprosthetic joint infection, and 4 (8%) died during hospital stay. The odds ratio for infection in the dialysis group was 7.54 (95% confidence interval: 2.83-20.12) and 10.46 (95% confidence interval: 1.67-65.34) for the inhospital mortality. We conclude that end-stage renal failure patients receiving hemodialysis have higher postoperative infection and inhospital mortality rates after an elective TJA procedure, whereas nondialysis CRF patients have similar outcomes compared with the general TJA population.

Delafloxacin, a fluoroquinolone, has activity against Gram-positive organisms including methicillin-resistant S aureus and fluoroquinolone-susceptible and -resistant Gram-negative organisms. The intravenous formulation of delafloxacin contains the excipient sulfobutylether-β-cyclodextrin (SBECD), which is eliminated by renal filtration. This study examined the pharmacokinetics and safety of SBECD after single intravenous (IV) infusions in subjects with renal impairment. The study was an open-label, parallel-group, crossover study in subjects with normal renal function or mild, moderate, or severe renal impairment, and those with end-stage renal disease undergoing hemodialysis. Subjects received 300 mg delafloxacin IV or placebo IV, containing 2400 mg SBECD, in 2 periods separated by ≥14-day washouts. SBECD total clearance decreased with decreasing renal function, with a corresponding increase in area under the concentration-time curve (AUC 0-∞ ). After IV delafloxacin 300 mg administration, SBECD mean total clearance was 6.28 and 1.24 L/h, mean AUC 0-∞ was 387 and 2130 h·μg/mL, and mean renal clearance was 5.36 and 1.14 L/h in normal and severe renal subjects, respectively. Similar values were obtained after IV placebo administration. In subjects with end-stage renal disease, delafloxacin 300 mg IV produced mean SBECD AUC 0-48 values of 2715 and 7861 h·μg/mL when dosed before and after hemodialysis, respectively. Total SBECD clearance exhibited linear relationships to estimated glomerular filtration rate and creatinine clearance. Single doses of IV delafloxacin 300 mg and IV placebo were well tolerated in all groups. In conclusion, decreasing renal function causes reduced SBECD clearance and increased exposures, but SBECD continues to exhibit a good safety and tolerability profile in IV formulations. © 2018, The American College of Clinical Pharmacology.

In recent years, more women are undergoing renal transplantation as a treatment for end-stage renal disease. Women with kidney transplants are prone to certain gynecologic issues which might necessitate hysterectomy. Laparoscopic hysterectomy can safely be performed in patients with prior unilateral or bilateral renal transplantation. Laparoscopy offers magnification of anatomy, decreased wound-related problems, and continuation of immunosuppression therapy. We present a case report and review of the literature for total laparoscopic hysterectomy and bilateral salpingectomy for a patient with prior bilateral renal transplant.

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.

Vascular access-related complications are a frequent cause of morbidity in haemodialysis patients and generate high costs. We present the case of an adult patient with end-stage renal disease and recurrent vascular access thrombosis associated with the prothrombin mutation G20210A and renal graft intolerance. The clinical expression of this heterozygous gene mutation may have been favoured by inflammatory state, frequent in dialysis patients. In this patient, the inflammatory response associated with the renal graft intolerance would have favored the development of recurrent vascular access thrombosis in a adult heterozygous for prothrombin mutation G20210A. In the case of early dysfunction of haemodialysis vascular access and after ruling out technical problems, it is convenient to carry out a screening for thrombophilia.

Mothers requiring dialysis to treat end-stage kidney disease face the challenging demands of the disease and dialysis treatment in addition to their role as a parent. To describe the experience of mothers who require haemodialysis. Four mothers receiving haemodialysis treatment for end-stage kidney disease in regional Australia were interviewed to explore the mothers' experiences, attitudes, beliefs and values of their dual role as mothers and haemodialysis recipients. The overarching theme emerging from the data was the competing roles of motherhood and dialysis. Four key sub-themes emerged: fitting everything in, internal family challenges, lost connections and striving for normality. Being a mother adds a range of complexities to being on dialysis. While managing dialysis, mothers struggle to care for their children and stay connected with family life. Nephrology health professionals are uniquely placed to support mothers and need to develop strategies to ease their burdens of care. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Background The overall risk of some cancers is increased in patients receiving regular dialysis treatment due to chronic oxidative stress, a weakened immune system and enhanced genomic damage. These patients could benefit from the same antineoplastic treatment delivered to patients with normal renal function, but a better risk/benefit ratio could be achieved by establishing specific guidelines. Key considerations are which chemotherapeutic agent to use, adjustment of dosages and timing of dialysis in relation to the administration of chemotherapy. Methods We have reviewed available data present in the literature, including recommendations and expert opinions on cancer risk and use of chemotherapeutic agents in patients with end-stage renal disease. Experts selected by the boards of the societies provided additional information which helped greatly in clarifying some issues on which clear-cut information was missing or available data were conflicting. Results Data on the optimal use of chemotherapeutic agents or on credible schemes of polychemotherapy in haemodialysed patients are sparse and mainly derive from case reports or small case series. However, recommendations on dosing and timing of dialysis can be proposed for the most prescribed chemotherapeutic agents. Discussion The use of chemotherapeutic agents as single agents, or in combination, can be safely given in patients with end-stage renal disease. Appropriate dosage adjustments should be considered based on drug dialysability and pharmacokinetics. Coordinated care between oncologists, nephrologists and pharmacists is of pivotal importance to optimise drug delivery and timing of dialysis. PMID:29209521

Anemia as a risk factor for chronic kidney disease.

PubMed

Iseki, K; Kohagura, K

2007-11-01

Chronic kidney disease (CKD) is an important and leading cause of end-stage renal disease (ESRD) and moreover, plays a role in the morbidity and mortality due to cardiovascular disease, infection, and cancer. Anemia develops during the early stages of CKD and is common in patients with ESRD. Anemia is an important cause of left ventricular hypertrophy and congestive heart failure. Correction of anemia by erthyropoiesis-stimulating agent (ESA) has been shown to improve survival in patients with congestive heart failure. Anemia is counted as one of the non-conventional risk factors associated with CKD. Hypoxia is one of the common mechanisms of CKD progression. Treatment by ESA is expected to improve quality of life, survival, and prevent the CKD progression. Several clinical studies have shown the beneficial effects of anemia correction on renal outcomes. However, recent prospective trials both in ESRD and in CKD stages 3 and 4 failed to confirm the beneficial effects of correcting anemia on survival. Similarly, treatment of other risk factors such as hyperlipidemia by statin showed no improvement in the survival of dialysis patients. Given the high prevalence of anemia in ESRD and untoward effects of anemia in CKD stages 3 and 4, appropriate and timely intervention on renal anemia using ESA is required for practicing nephrologists and others involved in the care of high-risk population. Lessons from the recent studies are to correct renal anemia (hemoglobin <10 g/dl not hemoglobin > or =13 g/dl). Early intervention for renal anemia is a part of the treatment option in the prevention clinic. In this study, clinical significance of anemia management in patients with CKD is discussed.

Peri-operative kidney injury and long-term chronic kidney disease following orthotopic heart transplantation in children.

PubMed

Hoskote, Aparna; Burch, Michael

2015-06-01

Significant advances in cardiac intensive care including extracorporeal life support have enabled children with complex congenital heart disease and end-stage heart failure to be supported while awaiting transplantation. With an increasing number of survivors after heart transplantation in children, the complications from long-term immunosuppression, including renal insufficiency, are becoming more apparent. Severe renal dysfunction after heart transplant is defined by a serum creatinine level >2.5 mg/dL (221 μmol/L), and/or need for dialysis or renal transplant. The degree of renal dysfunction is variable and is progressive over time. About 3-10 % of heart transplant recipients will go on to develop severe renal dysfunction within the first 10 years post-transplantation. Multiple risk factors for chronic kidney disease post-transplant have been identified, which include pre-transplant worsening renal function, recipient demographics and morbidity, peri-transplant haemodynamics and long-term exposure to calcineurin inhibitors. Renal insufficiency increases the risk of post-transplant morbidity and mortality. Hence, screening for renal dysfunction pre-, peri- and post-transplantation is important. Early and timely detection of renal insufficiency may help minimize renal insults, and allow prompt implementation of renoprotective strategies. Close monitoring and pre-emptive management of renal dysfunction is an integral aspect of peri-transplant and subsequent post-transplant long-term care.

This study aims to contribute to the discussion on the possibility of applying health economics assessment, specifically the cost-effectiveness technique, to renal replacement therapies for end-stage renal failure. A review was conducted on the interventions and their alternative courses from the perspective of the various methodological proposals in the literature, considering the availability of data and information in Brazil to back this type of research.

Haemodialysis in an emerging centre in a developing country: a two year review and predictors of mortality

PubMed Central

2011-01-01

Background Haemodialysis is the most common form of renal replacement therapy in Nigeria. The high cost of haemodialysis has made optimal therapy of end-stage renal disease difficult in Nigeria. This paper is a review of data collected over two years of provision of dialysis services in a new tertiary hospital in Southern Nigeria. Methods This retrospective analysis is done on data obtained from the patient case files and dialysis records in the first two years of provision of dialysis services in our centre. A gender comparison of the patients' baseline sociodemographic, clinical and biochemical was performed and a logistic regression model used to assess the predictors of mortality. Results A total of 98 patients had 471 sessions in the two years under review. Males and females had similar characteristics at baseline except for a higher median serum urea in the males. The commonest causes of end-stage renal disease were chronic glomerulonephritis (34.5%), hypertension (32.1%) and diabetes mellitus (17.9%). The main predictor of mortality was under treatment with haemodialysis due to inability to pay for more than a few dialysis sessions. Conclusions This study has highlighted the unchanging demographics of our advanced kidney failure patients. Efforts should be aimed at subsidizing the cost of dialysis for our teeming population of dialysis dependent chronic kidney disease patients. PMID:21962220

The study objective was to identify patients who are likely to develop progressive kidney dysfunction (acute kidney disease) before their hospital discharge after cardiac surgery, allowing targeted monitoring of kidney function in this at-risk group with periodic serum creatinine measurements. Risks of progression to acute kidney disease (a state in between acute kidney injury and chronic kidney disease) were modeled from acute kidney injury stages (Kidney Disease: Improving Global Outcomes) in patients undergoing cardiac surgery. A modified Poisson regression with robust error variance was used to evaluate the association between acute kidney injury stages and the development of acute kidney disease (defined as doubling of creatinine 2-4 weeks after surgery) in this observational study. Acute kidney disease occurred in 4.4% of patients with no preexisting kidney disease and 4.8% of patients with preexisting chronic kidney disease. Acute kidney injury predicted development of acute kidney disease in a graded manner in which higher stages of acute kidney injury predicted higher relative risk of progressive kidney disease (area under the receiver operator characteristic curve = 0.82). This correlation persisted regardless of baseline kidney function (P < .001). Of note, development of acute kidney disease was associated with higher mortality and need for renal replacement therapy. The degree of acute kidney injury can identify patients who will have a higher risk of progression to acute kidney disease. These patients may benefit from close follow-up of renal function because they are at risk of progressing to chronic kidney disease or end-stage renal disease.

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.

Prevalence and Risk Factors of Lower Limb Amputation in Patients with End-Stage Renal Failure on Dialysis: A Systematic Review

PubMed Central

Vangaveti, Venkat N.

2016-01-01

Background. Renal dialysis has recently been recognised as a risk factor for lower limb amputation (LLA). However, exact rates and associated risk factors for the LLA are incompletely understood. Aim. Prevalence and risk factors of LLA in end-stage renal failure (ESRF) subjects on renal dialysis were investigated from the existing literature. Methods. Published data on the subject were derived from MEDLINE, PubMed, and Google Scholar search of English language literature from January 1, 1980, to July 31, 2015, using designated key words. Results. Seventy studies were identified out of which 6 full-text published studies were included in this systematic review of which 5 included patients on haemodialysis alone and one included patients on both haemodialysis and peritoneal dialysis. The reported findings on prevalence of amputation in the renal failure on dialysis cohort ranged from 1.7% to 13.4%. Five out of the six studies identified diabetes as the leading risk factor for amputation in subjects with ESRF on renal dialysis. Other risk factors identified were high haemoglobin A1c, elevated c-reactive protein, and low serum albumin. Conclusions. This review demonstrates high rate of LLA in ESRF patients receiving dialysis therapy. It has also identified diabetes and markers of inflammation as risk factors of amputation in ESRF subjects on dialysis. PMID:27529033

Single-center evaluation of the single-dose pharmacokinetics of the angiotensin II receptor antagonist azilsartan medoxomil in renal impairment.

Azilsartan medoxomil (AZL-M) is a potent angiotensin II receptor blocker that decreases blood pressure in a dose-dependent manner. It is a pro-drug and not detected in blood after oral administration because of rapid hydrolysis to the active moiety, azilsartan (AZL). AZL undergoes further metabolism to the major metabolite M-II and minor metabolites. The objective of this study was to determine the effect of renal impairment on the pharmacokinetics of AZL and its major metabolite. This was a single-center, open-label, phase I parallel-group study which examined the single-dose (40-mg) pharmacokinetics of AZL and M-II in 24 subjects with mild, moderate, or severe renal impairment or end-stage renal disease requiring hemodialysis (n = 6 per group), respectively, and healthy matched subjects (n = 24). Renal impairment/disease did not cause clinically meaningful increases in exposure to AZL. M-II exposure was higher in all renally impaired subjects and highest in those with severe impairment (approx fivefold higher vs. control). M-II is pharmacologically inactive; increased exposure was not considered important in dose selection for AZL-M in subjects with renal impairment. Hemodialysis did not significantly remove AZL or M-II. Renal impairment had no clinically meaningful effect on the plasma protein binding of AZL or M-II. Single doses of AZL-M 40 mg were well tolerated in all subject groups. Based on the pharmacokinetic and tolerability findings, no dose adjustment of AZL-M is required for subjects with any degree of renal impairment, including end-stage renal disease.

Kidney dysfunction is a common clinical feature of symptomatic multiple myeloma. Some degree of renal insufficiency or renal failure is present at diagnosis or will occur during the course of the disease and, if not reversed, will adversely affect overall survival and quality of life. Chronic insults to the kidneys from other illnesses, treatment, or multiple myeloma itself can further damage renal function and increase the risk for additional complications, such as anemia. Patients with multiple myeloma who have light chain (Bence Jones protein) proteinuria may experience renal failure or progress to end-stage renal disease (ESRD) and require dialysis because of light chain cast nephropathy. Kidney failure in patients with presumed multiple myeloma also may result from amyloidosis, light chain deposition disease, or acute tubular necrosis caused by nephrotoxic agents; therefore, identification of patients at risk for kidney damage is essential. The International Myeloma Foundation's Nurse Leadership Board has developed practice recommendations for screening renal function, identifying positive and negative contributing risk and environmental factors, selecting appropriate therapies and supportive care measures to decrease progression to ESRD, and enacting dialysis to reduce and manage renal complications in patients with multiple myeloma.

Roux-en-Y gastric bypass (RYGB) surgery is currently one of the most popular procedures to aid weight loss. Hypoglycaemia associated with gastric bypass surgery is an underdiagnosed but life-threatening potential consequence of the surgical procedure. We present a case of a 44-year-old woman with end-stage renal disease presenting with refractory hypoglycaemia after 10 years of RYGB. Extensive history and work-up excluded medications, renal disease, insulinoma and dumping syndrome as the cause of hypoglycaemia. Dietary modifications or pharmacological trial of drugs did not ameliorate her symptoms with progressive worsening of hypoglycaemia leading to continuous dextrose infusion. Distal pancreatectomy was performed with subsequent resolution of hypoglycaemia. Surgical pathology results showed diffuse hyperplastic islet cells, confirming the diagnosis of postgastric bypass hypoglycaemia. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Addison's disease is a rare disorder in patients with end-stage renal disease (ESRD). In patients, the diagnosis of Addison's disease is difficult in clinical practice because most of the clinical findings of this disease are similar to those of the renal failure. We present a 51-year-old male patient, who underwent hemodialysis therapy for 8 years, diagnosed with Addison's disease after having myalgia, skin hyperpigmentation, weight loss, sweating, and nausea for the past few weeks. The physical examination was completely normal except for muscle weakness, hyperpigmentation on labial mucosa and skin in a patient. The laboratory tests revealed anemia and hypoglycemia. Serum cortisol, adrenocorticotropic hormone (ACTH) levels, and ACTH stimulation test results were consistent with Addison's disease. Adrenal computerized tomography revealed bilateral atrophic glands. Additionally, it was found that elevated serum thyroid stimulating hormone levels and antithyroid peroxidase antibody titer were positive. Our purpose is to emphasize that physicians should be alert to the potential for additional different conditions particularly in terms of adrenal failure in patients with ESRD.

Objective Case–control studies suggest hydrocarbons increase end-stage renal disease (ESRD) risk. No cohort studies have been conducted. Methods An occupational database was matched to the U.S. Renal Data System, and the outcome of all-cause ESRD was examined using multivariable Cox regression. Sixteen individual hydrocarbons were studied, although exposures were not mutually exclusive. Results For the 1973–2000 period, there was an approximate twofold increased risk of ESRD among workers exposed to trichloroethylene, 1,1,1-trichloroethane, and JP4 gasoline compared with unexposed subjects (all P < 0.05). Relative risk was greater than unity (P > 0.05) for several other hydrocarbons. Associations attenuated (all P > 0.05) when 2001–2002 data were included in the analyses. Conclusions Certain hydrocarbons may increase all-cause ESRD risk. Uncertainty regarding the mechanism for increased risk and the observed attenuation in risk in 2001–2002, as well as the overlap of exposures, complicates interpretation. Additional research is needed. PMID:16404204

The variants of angiotensin converting enzyme ( ACE ) and matrix metalloproteinases (MMPs) genes might be involved in the pathogenesis of end stage renal disease (ESRD) and hypertension. We studied the ACE insertion/deletion (I/D) and MMP-7 A-181G variants in 99 unrelated ESRD patients and 117 individuals without renal complications from Western Iran with Kurdish ethnic background. The frequency of ACE I/D variants was not significantly different between ESRD patients and controls. However, the presence of ACE D allele increased the risk of hypertension in ESRD patients by 2.14-fold (P=0.036). The MMP-7 -181 AG genotype increased the risk of ESRD by 2.04 times (P=0.026). The present study indicated the absence of an association between the ACE I/D polymorphism with the risk of ESRD. However, the ACE D allele increased the risk of hypertension in ESRD patients. Also, the present study suggests a role for MMP-7 AG genotype in the pathogenesis of ESRD.

Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited disease of the kidneys and is marked by progressive cyst growth and decline in kidney function, resulting in end-stage renal disease (ESRD). Hypertension is thought to be a significant modifying factor in the progression of renal failure in ADPKD. A number of genetic variations involved in renin-angiotensin-aldosterone system (RAAS) pathway genes have clinical or physiological impacts on pathogenesis of hypertension-induced ESRD in ADPKD. Information on RAAS pathway gene polymorphisms and their association with ESRD and ADPKD, published till March 2013, was collected using MEDLINE search. The present review deals with RAAS gene polymorphisms focused on hypertension-induced ESRD in ADPKD in different populations. The results were inconclusive and limited by heterogeneity in the study designs and the population stratification. In lieu of applying next generation sequencing technologies to study complex diseases, it is also possible to apply the same to unravel the complexity of ESRD in ADPKD.

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.

Approximately half of all deaths in patients with end-stage renal disease (ESRD) are due to cardiovascular diseases. Although renal transplant improves survival and quality of life in these patients, cardiovascular events significantly affect survival. We sought to evaluate coronary flow reserve (CFR), an indicator of coronary microvascular function, in patients with ESRD and in patients with a functioning kidney graft. Eighty-six patients (30 with ESRD, 30 with a functioning renal allograft, and 26 controls) free of coronary artery disease or diabetes mellitus were included. Transthoracic Doppler echocardiography was used to measure coronary peak flow velocities at baseline and after dipyridamole infusion. CFR was calculated as the ratio of hyperemic to baseline diastolic peak flow velocities and was compared among the groups. The mean age of the study population was 36.1+/-7.3 years. No between-group differences were found regarding age, sex, or prevalences of traditional coronary risk factors other than hypertension. Compared with the renal transplant and control groups, the ESRD group had significantly lower mean CFR values. On multivariate regression analysis, serum levels of creatinine, age, and diastolic dysfunction were independent predictors of CFR. CFR is impaired in patients with ESRD suggesting that coronary microvascular dysfunction, an early finding of atherosclerosis, is evident in these patients. Although associated with a decreased CFR compared with controls, renal transplant on the other hand seems to have a favorable effect on coronary microvascular function.

Xp11.2 translocation/transcription factor E3 (TFE3) rearrangement renal cell carcinoma (RCC) is a rare subtype of RCC with limited clinical and pathological data. Here we present an unusual high-grade Xp11.2 translocation RCC with a rhabdoid feature and SMARCB1 (INI1) inactivation in a 40-year-old man with end-stage kidney disease. The histological examination of the dissected left renal tumor showed an organoid architecture of the eosinophilic or clear neoplastic cells with necrosis and high mitotic activity. In some areas, non-adhesive tumor cells with eccentric nuclei were observed. Immunohistochemically (IHC), the tumor cells are positive for TFE3 and the renal tubular markers (PAX2 and PAX8), and completely negative for SMARCB1, an oncosuppressor protein. Break-apart florescence in situ hybridization and reverse transcription polymerase chain reaction confirmed TFE3 rearrangement on Xp11.2 and the presence of ASPSCR1-TFE3 fusion gene. DNA sequencing revealed a frameshift mutation in exon 4 of SMARCB1 gene. It is important to recognize this rare RCC with both TFE3 rearrangement and SMARCB1 inactivation, as the prognosis and therapeutic strategies, particularly targeted therapies for such tumors, might be different.

Acute postinfectious glomerulonephritis is common in indigenous communities in the Northern Territory, Australia. It is a major risk factor for the high prevalence of chronic kidney disease. We aimed to analyse the clinical presentation, pathological spectra, treatment and outcomes of biopsy-proven acute postinfectious glomerulonephritis in the Northern Territory. We performed a retrospective cohort analysis of all adult patients (≥18 years) who were diagnosed with acute postinfectious glomerulonephritis on native renal biopsies from 01/01/2004 to 31/05/2014. The outcome measure was end-stage renal disease requiring long-term dialysis. Forty-three of 340 patients who had renal biopsies had acute postinfectious glomerulonephritis. Most were Aboriginals (88.4%). They had co-morbidities; diabetes mellitus (60.5%), hypertension (60.5%) and smoking (56.4%). Forty-nine per cent had multiple pathologies on biopsy. Predominant histological pattern was diffuse proliferative glomerulonephritis (72%). Main sites of infections were skin (47.6%) and upper respiratory tract infection (26.2%) with streptococcus and staphylococcus as predominant organisms. Fifty per cent of patients developed end-stage renal disease. On multivariable logistic regression analysis, those on dialysis had higher baseline creatinine (P = 0.003), higher albumin/creatinine ratio at presentation (P = 0.023), higher serum creatinine at presentation (P = 0.02) and lower estimated glomerular filtration rate at presentation (P = 0.012). Overall, most patients had pre-existing pathology with superimposed acute postinfectious glomerulonephritis that led to poor outcomes in our cohort. © 2016 Asian Pacific Society of Nephrology.

The dynamic process of adherence to a renal therapeutic regimen: perspectives of patients undergoing continuous ambulatory peritoneal dialysis.

2014-06-01

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 dynamic as there were fluctuations at each stage of the participants' adherence. With reference to each stage identified, nursing interventions can be developed to help patients achieve smooth transition throughout all the stages. Copyright © 2013 Elsevier Ltd.

We report here the successful treatment of hepatitis C virus (HCV) transmitted from a nucleic acid testing (NAT)-negative donor to three HCV-negative recipients-two renal transplants and one liver. Both renal recipients underwent standard deceased-donor renal transplantation with immediate graft function. The liver recipient underwent standard orthotopic liver transplantation and recovered uneventfully. The donor was a 39-year-old woman with a terminal serum creatinine of 0.7 mg/dL. She was high risk for bloodborne pathogens, based upon a history of sexual contact with an HCV-infected male partner. Recipient 1 was a 45-year-old man with a history of end-stage renal disease from systemic lupus erythematosus. Recipient 2 was a 62-year-old woman with a history of end-stage renal disease caused by hypertension and insulin-dependent diabetes. Recipient 3 was a 42-year-old man with acute liver failure from acetaminophen ingestion. All recipients became HCV polymerase chain reaction positive on post-transplant follow-up. Both kidney recipients were treated with ledipasvir/sofosbuvir combination therapy for 12 weeks without side effects or rejection episodes. Recipient 3 was treated with ledipasvir/sofosbuvir in combination with ribavirin for 12 weeks without side effects. All patients achieved a sustained viral response at 12 weeks and are considered cured of HCV. The kidney recipients maintained good allograft function with a serum creatinine of 1.4 mg/dL and 1.0 mg/dL, respectively. Both renal recipients maintained normal liver function post treatment and did not develop any evidence of fibrosis. The liver recipient's liver function tests returned to normal without further incident. This case report provides evidence for the successful treatment of donor-derived HCV in transplant recipients. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Managing oral phosphate binder medication expenditures within the Medicare bundled end-stage renal disease prospective payment system: economic implications for large U.S. dialysis organizations.

PubMed

Park, Haesuk; Rascati, Karen L; Keith, Michael S

2015-06-01

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 with ESRD.

Pre-emptive liver transplantation for primary hyperoxaluria (PH-I) arrests long-term renal function deterioration.

2011-01-01

Primary hyperoxaluria-I (PH-I) is a serious metabolic disease resulting in end-stage renal disease. Pre-emptive liver transplantation (PLT) for PH-I is an option for children with early diagnosis. There is still little information on its effect on long-term renal function in this situation. Long-term assessment of renal function was conducted using Schwartz's formula (estimated glomerular filtration rate-eGFR) in four children (Group A) undergoing PLT between 2002 and 2008, and a comparison was done with eight gender- and sex-matched controls (Group B) having liver transplantation for other indications. All patients received a liver graft from a deceased donor. Median follow-up for the two groups was 64 and 94 months, respectively. One child in Group A underwent re-transplantation due to hepatic artery thrombosis, while acute rejection was seen in one. A significant difference was seen in eGFR at transplant (81 vs 148 mL/min/1.73 m(2)) with greater functional impairment seen in the study population. In Group A, renal function reduced by 21 and 11% compared with 37 and 35% in Group B at 12 and 24 months, respectively. At 2 years post-transplantation, there was no significant difference in eGFR between the two groups (72 vs 100 mL/min/1.73 m(2), respectively; P = 0.06). Renal function remains relatively stable following pre-emptive LTx for PH-I. With early diagnosis of PH-I, isolated liver transplantation may prevent progression to end-stage renal disease and the need for renal transplantation.

We reported a case of spontaneous retroperitoneal hematoma (SRH) simulating a ruptured infrarenal aortic aneurysm. A 72-year-old man with a history of infrarenal aortic aneurysm and end-stage renal disease on hemodialysis presented with malaise and nonspecific central abdominal pain and left loin discomfort. An emergency computed tomography scan showed a large retroperitoneal hematoma and clinical suspicion of ruptured infrarenal aortic aneurysm. However, the hematoma was discontinuous with the aneurysm sac and raised the clinical suspicion on dual pathology. The SRH was treated conservatively with transfusion of blood products, and the aneurysm was treated with nonemergency endovascular repair electively. This case demonstrates the importance of recognizing different clinical and radiological characteristics and be aware of dual pathology. PMID:28031651

Objective To assess for the presence of a sex interaction in the associations of estimated glomerular filtration rate and albuminuria with all-cause mortality, cardiovascular mortality, and end stage renal disease. Design Random effects meta-analysis using pooled individual participant data. Setting 46 cohorts from Europe, North and South America, Asia, and Australasia. Participants 2 051 158 participants (54% women) from general population cohorts (n=1 861 052), high risk cohorts (n=151 494), and chronic kidney disease cohorts (n=38 612). Eligible cohorts (except chronic kidney disease cohorts) had at least 1000 participants, outcomes of either mortality or end stage renal disease of ≥50 events, and baseline measurements of estimated glomerular filtration rate according to the Chronic Kidney Disease Epidemiology Collaboration equation (mL/min/1.73 m2) and urinary albumin-creatinine ratio (mg/g). Results Risks of all-cause mortality and cardiovascular mortality were higher in men at all levels of estimated glomerular filtration rate and albumin-creatinine ratio. While higher risk was associated with lower estimated glomerular filtration rate and higher albumin-creatinine ratio in both sexes, the slope of the risk relationship for all-cause mortality and for cardiovascular mortality were steeper in women than in men. Compared with an estimated glomerular filtration rate of 95, the adjusted hazard ratio for all-cause mortality at estimated glomerular filtration rate 45 was 1.32 (95% CI 1.08 to 1.61) in women and 1.22 (1.00 to 1.48) in men (Pinteraction<0.01). Compared with a urinary albumin-creatinine ratio of 5, the adjusted hazard ratio for all-cause mortality at urinary albumin-creatinine ratio 30 was 1.69 (1.54 to 1.84) in women and 1.43 (1.31 to 1.57) in men (Pinteraction<0.01). Conversely, there was no evidence of a sex difference in associations of estimated glomerular filtration rate and urinary albumin-creatinine ratio with end stage renal disease risk. Conclusions Both sexes face increased risk of all-cause mortality, cardiovascular mortality, and end stage renal disease with lower estimated glomerular filtration rates and higher albuminuria. These findings were robust across a large global consortium. PMID:23360717

Sleep disorders in kidney disease.

De Santo, R M; Perna, A; Di Iorio, B R; Cirillo, M

2010-03-01

Sleep disorders are common in patients with end stage renal disease receiving hemodialysis or peritoneal dialysis. However also a well functioning renal graft does not cure the poor sleep pattern which now emerges as a problem even in early chronic kidney disease (CKD). When patients are made aware for the first time of a disease such as CKD, which may brink to dialysis or at the best to a renal transplant patients begin to experience a disordered sleep. Sleeping disorders include insomnia (I), sleep apnoea (SAS), restless legs syndrome (RLS), periodic limb movement disorder (PLMD), excessive daily sleeping (EDS), sleepwalking, nightmares, and narcolepsy. Disordered sleep did not meet the clinical and scientific interest it deserves, in addition and we do not have a well defined solution for sleeping complaints. However, awareness that a poor sleep is associated with poor quality of life and carries an increase in mortality risk has recently stimulated interest in the field. There are many putative causes for a disordered sleep in chronic kidney disease and in end-stage renal disease. For a unifying hypothesis demographic factors, lifestyles, disease related factors, psychological factors, treatment related factors, and social factor must be taken into consideration.

Primary hyperoxaluria (PH) is a very rare genetic disorder; it is characterized by total or partial deficiency of the enzymes related to the metabolism of glyoxylate, with an overproduction of calcium oxalate that is deposited in different organs, mainly the kidney, leading to recurrent lithiasis, nephrocalcinosis and end stage renal disease (ESRD). In patients with ESRD that receive kidney transplantation alone, the disease has a relapse of 100%, with graft loss in a high percentage of patients in the first 5 years of transplantation. Three molecular disorders have been described in PH: mutation of the gene alanin glioxalate aminotransferase (AGXT); glyoxalate reductase/hydroxy pyruvate reductase (GRHPR) and 4-OH-2-oxoglutarate aldolase (HOGA1). We present two cases of patients with a history of renal lithiasis who were diagnosed with primary hyperoxaluria in the post-transplant period, manifested by early graft failure, with evidence of calcium oxalate crystals in renal biopsy, hyperoxaluria, hyperoxalemia, and genetic test compatible; they were managed with proper diet, abundant oral liquids, pyridoxine, hydrochlorothiazide and potassium citrate; however, they had slow but progressive deterioration of their grafts function until they reached end-stage chronic renal disease.

Limitation on the use of amiloride in early renal failure.

PubMed

Knauf, H; Reuter, K; Mutschler, E

1985-01-01

The effect of a single oral dose of 10 mg amiloride was studied on urinary excretion of Na+, K+, Ca++ and Mg++ in healthy subjects and in patients with varying degrees of renal impairment. Amiloride produced a moderate diuresis and sodium excretion, and a slight calciuresis. Urinary excretion of potassium was significantly reduced as compared to the controls. Despite its diuretic and natriuretic effects, amiloride did not change the excretion of Mg++ as compared to the pretreatment period. When the creatinine clearance was below 50 ml/min, the net excretion of Na+ and Ca++ was drastically reduced. However, K+ retention and neutrality of Mg++ excretion were maintained down to end-stage renal disease. In the healthy volunteers the mean elimination half-life of amiloride was 20 h, and it rose to about 100 h in end-stage renal disease. This was because about 3/4 of native amiloride was eliminated through the kidney. Nonrenal elimination of amiloride was calculated to amount to only 1/4 of the total elimination. Therefore, the anticaliuretic amiloride is a valuable comedication in subjects with normal kidney function to prevent K+ and Mg++ loss. However, its use is hazardous if plasma creatinine is raised.

Systemic Redox Imbalance in Chronic Kidney Disease: A Systematic Review

Patients with chronic kidney disease (CKD) experience imbalance between oxygen reactive species (ROS) production and antioxidant defenses leading to cell and tissue damage. However, it remains unclear at which stage of renal insufficiency the redox imbalance becomes more profound. The aim of this systematic review was to provide an update on recent advances in our understanding of how the redox status changes in the progression of renal disease from predialysis stages 1 to 4 to end stage 5 and whether the various treatments and dialysis modalities influence the redox balance. A systematic review was conducted searching PubMed and Scopus by using the Cochrane and PRISMA guidelines. In total, thirty-nine studies met the inclusion criteria and were reviewed. Even from an early stage, imbalance in redox status is evident and as the kidney function worsens it becomes more profound. Hemodialysis therapy per se seems to negatively influence the redox status by the elevation of lipid peroxidation markers, protein carbonylation, and impairing erythrocyte antioxidant defense. However, other dialysis modalities do not so far appear to confer advantages. Supplementation with antioxidants might assist and should be considered as an early intervention to halt premature atherogenesis development at an early stage of CKD. PMID:27563376

Polycystin-1 Cleavage and the Regulation of Transcriptional Pathways

PubMed Central

Merrick, David; Bertuccio, Claudia A.; Chapin, Hannah C.; Lal, Mark; Chauvet, Veronique; Caplan, Michael J.

2013-01-01

Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic cause of end stage renal disease, affecting ~1 in 1,000 people. The disease is characterized by the development of numerous large fluid filled renal cysts over the course of decades. These cysts compress the surrounding renal parenchyma and impair its function. Mutations in two genes are responsible for ADPKD. The protein products of both of these genes, polycystin-1 and polycystin-2, localize to the primary cilium and participate in a wide variety of signaling pathways. Polycystin-1 undergoes several proteolytic cleavages that produce fragments that manifest biological activities. Recent results suggest that the production of polycystin-1 cleavage fragments is necessary and sufficient to account for at least some, although certainly not all, of the physiological functions of the parent protein.

Previous studies have shown that exercise training in patients with end-stage renal disease could improve their physical functioning and quality of life. Nevertheless, few studies have evaluated the effects of Tai Chi exercise in patients on hemodialysis. To investigate the effects of a Tai Chi exercise intervention on the quality of life and physical functioning in end-stage renal disease patients on hemodialysis. A pre-post experimental design. Patients, aged 20 years or older, on hemodialysis recruited from the hemodialysis unit at a medical center in central Taiwan were assigned, based on their own preference, to either a control group (n=25) or an intervention group (n=21). A weekly one-hour short-form Yang style Tai Chi session for a total of 12 weeks. Physical functioning and Kidney Disease Quality of Life (KDQOL) at the baseline and at the end of the intervention. The least square means of repetition of sit-to-stand cycles in one minute (STS-60), 6-min walk test, and gait speed test were significantly improved in the intervention group. In addition, the least square means of the five different dimensions of the KDQOL were all significantly higher in the intervention group, except the SF-12 physical health score. Improvements in the kidney disease quality of life and physical functioning were observed in Taiwanese patients on hemodialysis with a 12-week Tai Chi exercise intervention. Copyright © 2016.

Acute kidney injury: not just acute renal failure anymore?

PubMed

Dirkes, Susan

2011-02-01

Until recently, no uniform standard existed for diagnosing and classifying acute renal failure. To clarify diagnosis, the Acute Dialysis Quality Initiative group stated its consensus on the need for a clear definition and classification system of renal dysfunction with measurable criteria. Today the term acute kidney injury has replaced the term acute renal failure, with an understanding that such injury is a common clinical problem in critically ill patients and typically is predictive of an increase in morbidity and mortality. A classification system, known as RIFLE (risk of injury, injury, failure, loss of function, and end-stage renal failure), includes specific goals for preventing acute kidney injury: adequate hydration, maintenance of renal perfusion, limiting exposure to nephrotoxins, drug protective strategies, and the use of renal replacement therapies that reduce renal injury.

Impaired renal function and development in Belgrade rats

PubMed Central

Veuthey, Tania; Hoffmann, Dana; Vaidya, Vishal S.

2013-01-01

Belgrade rats carry a disabling mutation in the iron transporter divalent metal transporter 1 (DMT1). Although DMT1 plays a major role in intestinal iron absorption, the transporter is also highly expressed in the kidney, where its function remains unknown. The goal of this study was to characterize renal physiology of Belgrade rats. Male Belgrade rats died prematurely with ∼50% survival at 20 wk of age. Necropsy results indicated marked glomerular nephritis and chronic end-stage renal disease. By 15 wk of age, Belgrade rats displayed altered renal morphology associated with sclerosis and fibrosis. Creatinine clearance was significantly lower compared with heterozygote littermates. Urinary biomarkers of kidney injury, including albumin, fibrinogen, and kidney injury molecule-1, were significantly elevated. Pilot morphological studies suggest that nephrogenesis is delayed in Belgrade rat pups due to their low iron status and fetal growth restriction. Such defects in renal development most likely underlie the compromised renal metabolism observed in adult b/b rats. Belgrade rat kidney nonheme iron levels were not different from controls but urinary iron and transferrin levels were higher. These results further implicate an important role for the transporter in kidney function not only in iron reabsorption but also in glomerular filtration of the serum protein. PMID:24226520

Growth impairment, microcephaly and developmental delay in young children with chronic renal failure improve after successful renal transplantation. There have been few reports on head circumference (HC) and development after transplantation. Standard deviation scores (SDS) of height and HC and developmental quotient (DQ) after successful renal transplantation were evaluated in 12 recipients under 5 years of age. At the time of transplantation their mean age was 2.5 years and mean bodyweight was 9.0 kg. Mean height SDS was -3.0 at transplantation and increased to -2.3 at 1 year after transplant (P = 0.002). Mean HC-SDS increased from -1.4 to -0.9 at 1 year after transplant (P = 0.02). As for each category of DQ examined 1 year after transplant, mean scores of gross motor function, basic practice, personal relations, speech and recognition increased from 69 to 90 (P = 0.007), from 77 to 102 (P = 0.02), from 87 to 103 (P = 0.04), from 71 to 90 (P = 0.0006), and from 88 to 101 (P = 0.03), respectively. In young children, physical growth, HC growth and DQ scores increased 1 year after transplantation. Dialysis and transplantation program should be planned in young children with end-stage renal failure in anticipation of growth and development of each patient.

While much has been learned about the epidemiology and treatment of end-stage renal disease (ESRD) in the last 30 years, chronic kidney disease (CKD) before the end-stage has been less investigated. Not enough is known about factors associated with CKD progression and complications, as well as its transition to ESRD. We designed the CKD-renal epidemiology and information network (REIN) cohort to provide a research platform to address these key questions and to assess clinical practices and costs in patients with moderate or advanced CKD. A total of 46 clinic sites and 4 renal care networks participate in the cohort. A stratified selection of clinic sites yields a sample that represents a diversity of settings, e.g. geographic region, and public versus for-profit and non-for-profit private clinics. In each site, 60-90 patients with CKD are enrolled at a routine clinic visit during a 12-month enrolment phase: 3600 total, including 1800 with Stage 3 and 1800 with Stage 4 CKD. Follow-up will continue for 5 years, including after initiation of renal replacement therapy. Data will be collected from medical records at inclusion and at yearly intervals, as well as from self-administered patient questionnaires and provider-level questionnaires. Patients will also be interviewed at baseline, and at 1, 3 and 5 years. Healthcare costs will also be determined. Blood and urine samples will be collected and stored for future studies on all patients at enrolment and at study end, and at 1 and 3 years in a subsample of 1200. The CKD-REIN cohort will serve to improve our understanding of the biological, clinical and healthcare system determinants associated with CKD progression and adverse outcomes as well as of international variations in collaboration with the CKD Outcome and Practice Pattern Study (CKDopps). It will foster CKD epidemiology and outcomes research and provide evidence to improve the health and quality of life of patients with CKD and the performances of the healthcare system in this field. © The Author 2013.

Summary Background For patients with end-stage renal disease who are not candidates for fistula, dialysis access grafts are the best option for chronic haemodialysis. However, polytetrafluoroethylene arteriovenous grafts are prone to thrombosis, infection, and intimal hyperplasia at the venous anastomosis. We developed and tested a bioengineered human acellular vessel as a potential solution to these limitations in dialysis access. Methods We did two single-arm phase 2 trials at six centres in the USA and Poland. We enrolled adults with end-stage renal disease. A novel bioengineered human acellular vessel was implanted into the arms of patients for haemodialysis access. Primary endpoints were safety (freedom from immune response or infection, aneurysm, or mechanical failure, and incidence of adverse events), and efficacy as assessed by primary, primary assisted, and secondary patencies at 6 months. All patients were followed up for at least 1 year, or had a censoring event. These trials are registered with ClinicalTrials.gov, NCT01744418 and NCT01840956. Findings Human acellular vessels were implanted into 60 patients. Mean follow-up was 16 months (SD 7·6). One vessel became infected during 82 patient-years of follow-up. The vessels had no dilatation and rarely had post-cannulation bleeding. At 6 months, 63% (95% CI 47–72) of patients had primary patency, 73% (57–81) had primary assisted patency, and 97% (85–98) had secondary patency, with most loss of primary patency because of thrombosis. At 12 months, 28% (17–40) had primary patency, 38% (26–51) had primary assisted patency, and 89% (74–93) had secondary patency. Interpretation Bioengineered human acellular vessels seem to provide safe and functional haemodialysis access, and warrant further study in randomised controlled trials.

Posttransplant antiglomerular basement membrane (anti-GBM) disease occurs in approximately 5% of Alport patients and usually ends in irreversible graft failure. Recent research has focused on characterizing the structure of the anti-GBM alloepitope. Here we present a case of a 22-year-old male with end-stage renal disease secondary to Alport syndrome, with a previously failed renal allograft, who received a second deceased-donor kidney transplant. Six days after transplantation, he developed acute kidney injury. The serum anti-GBM IgG was negative by enzyme immunoassay (EIA). On biopsy, he had crescentic glomerulonephritis with linear GBM fixation of IgG. With further analysis by western blotting, we were able to detect antibodies to an unidentified protein from the basement membrane. This patient was treated with plasmapheresis twice per week and monthly intravenous immunoglobulin (IVIG) for a total of five months. At the end of treatment, these unknown antibodies were no longer detected. His renal function improved, and he has not required dialysis. We conclude that anti-GBM disease in patients with Alport Syndrome may be caused by circulating antibodies to other components of the basement membrane that are undetectable by routine anti-GBM EIA and may respond to treatment with plasmapheresis and IVIG.

Signaling by TGF-β/Smad3 plays a key role in renal fibrosis. As obesity is one of the major risk factors of chronic and end-stage renal disease, we studied the role of Smad3 signaling in the pathogenesis of obesity-related renal disease. After switching to a high fat diet, the onset of Smad3 C-terminal phosphorylation, increase in albuminuria, and the early stages of peripheral and renal insulin resistance occurred at 1 day, and 4 and 8 weeks, respectively, in C57BL/6 mice. The loss of synaptopodin, a functional marker of podocytes, and phosphorylation of the Smad3 linker region (T179 and S213) appeared after 4 weeks of the high fat diet. This suggests a temporal pattern of Smad3 signaling activation leading to kidney injury and subsequent insulin resistance in the development of obesity-related renal disease. In vivo, Smad3 knockout attenuated the high fat diet-induced proteinuria, renal fibrosis, overall podocyte injury, and mitochondrial dysfunction in podocytes. In vitro palmitate caused a rapid activation of Smad3 in 30 min, loss of synaptopodin in 2 days, and impaired insulin signaling in 3 days in isolated mouse podocytes. Blockade of either Smad3 phosphorylation by SIS3 (a Smad3 inhibitor) or T179 phosphorylation by flavopiridol (a CDK9 inhibitor) prevented the palmitate-induced loss of synaptopodin and mitochondrial function in podocytes. Thus, Smad3 signaling plays essential roles in obesity-related renal disease and may be a novel therapeutic target.

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.

SELL (L-selectin) is a candidate gene for several complex diseases including diabetes mellitus and renal failure. Our aim was to investigate the involvement of P213S SELL gene polymorphism (rs2229569) in type 2 diabetes mellitus (T2DM) and related end stage renal disease (ESRD). Type 2 diabetes mellitus patients without ESRD (n=250) or with ESRD (n=90), ESRD patients without diabetes (n=119) and sex and age matched healthy subjects (n=459) were analyzed in this study. DNA samples from all these subjects were genotyped for the P213S polymorphism by PCR-RFLP technique. Statistical analysis indicated that SELL P213S genotypes and alleles were similar distributed in the patients and control groups (ORSS=0.37, CI 95%: 0.131>0.372>1.06, p=0.05, Yate's correction p=0.09, for T2DM patients without ESRD, ORSS=2.04, CI 95%: 0.365>2.047>1.465, p=0.4, Yate's correction p=0.67, for T2DM patients with ESRD and ORSS=1, CI95%: 0.198>1>5.057, p=1, Yate's correction p=0.67, for non-diabetic with ESRD patients). Also, no significant differences were noticed when we compared the ESRD subjects with diabetes vs. non-diabetic ones (OR=1.798, CI 95%: 0.392>1.798>8.245, p=0.44, Yate's correction p=0.7). No statistically significant results were found in order to sustain the hypothesis of association between SELL gene P213S polymorphism, type 2 diabetes mellitus and end stage renal disease.

Background It is thought that hyperuricemia might lower the risk of mortality among hemodialysis patients, unlike in the general population, but the evidence is controversial. The aim of the current study was to evaluate the impact of serum uric acid level on the long-term clinical outcomes of hemodialysis patients in Korea. Methods Retrospective analysis was performed on data from the End-Stage Renal Disease Registry of the Korean Society of Nephrology. This included data for 7,333 patients (mean age, 61 ± 14 years; 61% male) who received hemodialysis from January 2001 through April 2015. Initial laboratory data were used in the analysis. Results The mean serum uric acid level in this study was 7.1 ± 1.7 mg/dL. Body mass index, normalized protein catabolic rate, albumin, and cholesterol were positively correlated with serum uric acid level after controlling for age and sex. After controlling for demographic data, comorbidities, and residual renal function, a higher uric acid level was independently associated with a significantly lower all-cause mortality (hazard ratio [HR], 0.90 per 1 mg/dL increase in uric acid level; 95% confidence interval [CI], 0.83–0.97; P = 0.008), but not cardiovascular mortality (HR, 0.90; 95% CI, 0.80–1.01; P = 0.078). Comparing uric acid levels in the highest and lowest quintiles, the HR for all-cause mortality was 0.65 (95% CI, 0.42–0.99; P = 0.046). Conclusion Hyperuricemia was strongly associated with a lower risk of all-cause mortality, but there seems to be no significant association between serum uric acid level and cardiovascular mortality among Korean hemodialysis patients with end-stage renal disease.

The high mortality rate in end-stage renal disease has engendered interest in nontraditional atherosclerotic cardiovascular disease (ASCVD) risk factors that are more prevalent in end-stage renal disease, such as elevated lipoprotein(a) [Lp(a)] levels. Previous studies suggest that high Lp(a) levels and small apolipoprotein(a) [apo(a)] isoform size are associated with ASCVD, but none have investigated the relationship between Lp(a) level, apo(a) size, and mortality. An inception cohort of 864 incident dialysis patients was followed prospectively. Lp(a) was measured by an apo(a) size-independent ELISA and apo(a) size by Western blot after SDS-agarose gel electrophoresis. Comorbid conditions were determined by medical record review. Time to death was ascertained through dialysis clinic and Health Care Financing Administration follow-up. Survival analyses were performed with adjustment for baseline demographic, comorbid conditions, albumin, and lipids. Median follow-up was 33.7 months, with 346 deaths, 162 transplantations, and 10 losses to follow-up during 1999 person-years of follow-up. Cox regression analysis showed no association between Lp(a) level and mortality. However, an association between small apo(a) isoform size and mortality was found (hazard ratio, 1.36; P=0.004) after adjusting for age, race, sex, comorbidity score, cause of renal disease, and congestive heart failure. The association was somewhat lower in white patients (hazard ratio 1.34; P=0.019) than in black patients (1.69; P=0.04). No interaction by age, race, sex, diabetes, ASCVD, or Lp(a) level was present. Small apo(a) size, but not Lp(a) level, independently predicts total mortality risk in dialysis patients.

Patients with end-stage renal failure are a high-risk group for atherosclerotic cardiovascular disease and commonly have dyslipidemia as a major factor. Dietary manipulation is the recommended first line of therapy for reducing lipid levels in people with normal renal function; however, complex dietary requirements of dialysis-treated patients with end-stage renal failure impose significant constraints. In this study, we evaluated the effect of trying to comply with established lipid-lowering recommendations superimposed on our normally prescribed dialysis diet over 14 weeks in stable subjects treated with either hemodialysis (HD) or chronic peritoneal dialysis (PD). Of 306 dialysis patients screened, 75 subjects were enrolled; 8 subjects did not complete the study. In the remainder, HD subjects (n = 41) decreased saturated fat intakes by 18% overall and cholesterol intakes by 16%. This was associated with a decrease in total cholesterol levels from 232 +/- 8 to 209 +/- 4 mg/dL (mean +/- SEM; P = 0.007) and low-density lipoprotein cholesterol levels from 147 +/- 4 to 131 +/- 4 mg/dL (P = 0.009). However, energy intakes decreased by almost 10%. There were no statistically significant changes in PD patients (n = 26). Only 24.4% of HD (10 of 41 patients) and 15.4% of PD patients (4 of 26 patients) normalized their lipid levels. Considerable problems were encountered in maintaining compliance with the modified dialysis diets. This study shows that if adhered to, properly constructed dialysis diets are close to optimal lipid-lowering recommendations. Further dietary manipulation is difficult, leads to little benefit in the majority, and is accompanied by added problems of adherence. We conclude that the vast majority of dyslipidemic patients with end-stage renal failure require pharmacological therapy.

End-stage renal disease (ESRD) is associated with increased cardiovascular risk factors, electrolyte imbalances, and iron deficiency anemia. These factors may increase the risk of adverse outcomes in patients undergoing panniculectomy. There is a paucity of data regarding outcomes in patients with ESRD undergoing panniculectomy. The purpose of this study is to investigate whether ESRD is associated with increased rate of complications following a panniculectomy. The Nationwide Inpatient Sample database (2006-2011) was used to identify patients who underwent a panniculectomy. Among this cohort, patients diagnosed with end-stage renal disease were identified. Patients excluded from the study were emergency admissions, pregnant women, patients less than 18 years old, and patients with concurrent nephrectomy or kidney transplants. Demographic factors, comorbidities, and postoperative complications were evaluated. Chi-squared and risk-adjusted multivariate logistic regression analyses were performed to determine whether end-stage renal disease was associated with increased rate of postoperative complications. A total of 34,779 panniculectomies were performed during the study period. Of these, 613 (1.8%) were diagnosed with ESRD. Patients with ESRD were older (mean age 58.9 vs. 49.3, p < 0.01) and more likely to have Medicare (63.5 vs. 18.4%, p < 0.01). They had higher rates of comorbidities, including diabetes, hypertension, congestive heart failure, chronic lung disease, chronic anemia, liver disease, peripheral artery disease, obesity, and coagulopathies (p < 0.01). The procedure was more likely to occur at a large, teaching hospital (p < 0.01). Postoperatively, patients with ESRD had a higher rate of death (3.3 vs. 0.2%, p < 0.01), wound complications (10.6 vs. 6.2%, p < 0.01), venous thromboembolism (4.9 vs. 0.8%, p < 0.01), blood transfusions (25.3% vs. 7.0%, p < 0.01), non-renal major medical complications (40.0% vs. 8.4%), and longer hospital stay (9.2 vs. 3.8 days, p < 0.01). Multivariate logistic regression analysis controlling for age, race, sex, hospital location/teaching hospital, payer, and all comorbidities demonstrated that ESRD was independently associated with increased venous thromboembolisms (OR 2.38, 95% CI 1.48-3.83) and non-renal major medical complications (OR 1.51, 95% CI 1.19-1.91). ESRD was not independently associated with increased rate of wound complications or transfusions. Patients with ESRD are at increased risk of VTE and non-renal major medical complications following panniculectomy. Moreover, patients with ESRD have longer hospital stays and higher rates of mortality. This journal requires that authors assign a level of evidence to each article.

In 2012, about 16487 people received kidney transplants in the United States, whereas 95022 candidates were on the waiting list by the end of the year. Despite advances in renal transplant immunology, approximately 40% of recipients will die or lose graft within 10 years. The limitations of current therapies for renal failure have led researchers to explore the development of modalities that could improve, restore, or replace the renal function. The aim of this paper is to describe a reasonable approach for kidney regeneration and review the current literature regarding cell sources and mechanisms to develop a bioengineering kidney. Due to kidneys peculiar anatomy, extracellular matrix based scaffolds are rational starting point for their regeneration. The perfusion of detergents through the kidney vasculature is an efficient method for delivering decellularizing agents to cells and for removing of cellular material from the tissue. Many efforts have focused on the search of a reliable cell source to provide enrichment for achieving stable renal cell systems. For an efficient bioengineered kidney, these cells must be attached to the organ and then maturated into the bioractors, which simulates the human body environment. A functional bioengineered kidney is still a big challenge for scientists. In the last ten years we have got many improvements on the field of solid organ regeneration; however, we are still far away from the main target. Currently, regenerative centers worldwide have been striving to find feasible strategies to develop bioengineered kidneys. Cell-scaffold technology gives hope to end-stage renal disease patients who struggle with morbidity and mortality due to extended periods on dialysis or immunosupression. The potential of bioengineered organ is to provide a reliable source of organs, which can be refunctionalized and transplanted. PMID:25332894

International study of health care organization and financing: development of renal replacement therapy in Germany.

PubMed

Kleophas, Werner; Reichel, Helmut

2007-09-01

The German health system represents the case of a global budget with negotiated fees and competing medical insurance companies. Physicians in private practice and non-profit dialysis provider associations provide most dialysis therapy. End-stage renal disease (ESRD) modalities are well integrated into the overall health care system. Dialysis therapy, independent of the mode of treatment, is reimbursed at a weekly flat rate. Mandatory health insurance covers health expenses, including those related to ESRD, for more than 90% of the population. Both employees and employers contribute to the premium for this insurance. Private medical insurance covers the remainder of the population. Access to treatment, including dialysis therapy, is uniformly available.

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

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 allocation of treatment but, more importantly, it is a model that is morally, legally and ethically more defensible.

Objective The aim of this study was to investigate the presence of anti-carbonic anhydrase (CA II) autoantibodies in patients with end-stage renal disease (ESRD) and relationships between the autoantibody titers and ghrelin, glucose, blood urea nitrogen (BUN) and creatinine. Subjects and Methods Serum CA II autoantibody titers, malondialdehyde (MDA), BUN, creatinine and ghrelin levels were measured in 45 ESRD patients and 45 healthy subjects. Results The CA II autoantibody titers in the ESRD group (0.170 ± 0.237) were significantly higher than those in the control group (0.079 ± 0.032; p = 0.035). MDA and ghrelin levels were also significantly higher in the ESRD group (p < 0.001). A weak positive correlation was determined between anti-CA II antibody titers and MDA, and a negative correlation was observed between ghrelin levels and anti-CA II antibody titers (r = 0.287, p = 0.028 and r =b −0.278, p = 0.032, respectively). Conclusions In ESRD patients, the results showed the development of an autoimmune response against CA II. This suggests that anti-CA II antibodies could be involved in the pathogenesis of ESRD.

Cell therapy for the treatment of renal failure in the acute setting has proved successful, with therapeutic impact, yet development of a sustainable, portable bioartificial kidney for treatment of chronic renal failure has yet to be realized. Challenges in maintaining an anticoagulated blood circuit, the typical platform for solute clearance and support of the biological components, have posed a major hurdle in advancement of this technology. This group has developed a Bioartificial Renal Epithelial Cell System (BRECS) capable of differentiated renal cell function while sustained by body fluids other than blood. To evaluate this device for potential use in end-stage renal disease, a large animal model was established that exploits peritoneal dialysis fluid for support of the biological device and delivery of cell therapy while providing uraemic control. Anephric sheep received a continuous flow peritoneal dialysis (CFPD) circuit that included a BRECS. Sheep were treated with BRECS containing 1 × 10 8 renal epithelial cells or acellular sham devices for up to 7 days. The BRECS cell viability and activity were maintained with extracorporeal peritoneal fluid circulation. A systemic immunological effect of BRECS therapy was observed as cell-treated sheep retained neutrophil oxidative activity better than sham-treated animals. This model demonstrates that use of the BRECS within a CFPD circuit embodies a feasible approach to a sustainable and effective wearable bioartificial kidney. Copyright © 2016 John Wiley & Sons, Ltd.

Few studies have been conducted on the long-term prognosis of patients with amyloid light chain (AL) and amyloid A (AA) renal amyloidosis in the same cohort. We retrospectively examined 68 patients with biopsy-proven renal amyloidosis (38 AL and 30 AA). Clinicopathological findings at the diagnosis and follow-up data were evaluated in each patient. We analyzed the relationship between clinicopathological parameters and survival data. Significant differences were observed in several clinicopathological features, such as proteinuria levels, between the AL and AA groups. Among all patients, 84.2 % of the AL group and 93.3 % of the AA group received treatments for the underlying diseases of amyloidosis. During the follow-up period (median 18 months in AL and 61 months in AA), 36.8 % of the AL group and 36.7 % of the AA group developed end-stage renal failure requiring dialysis, while 71.1 % of the AL group and 56.7 % of the AA group died. Patient and renal survivals were significantly longer in the AA group than in the AL group. eGFR of >60 mL/min/1.73 m 2 at biopsy and an early histological stage of glomerular amyloid deposition were identified as low-risk factors. A multivariate analysis showed that cardiac amyloidosis and steroid therapy significantly influenced patient and renal survivals. Our results showed that heart involvement was the major predictor of poor outcomes in renal amyloidosis, and that the prognosis of AA renal amyloidosis was markedly better than that in previously reported cohorts. Therapeutic advances in inflammatory diseases are expected to improve the prognosis of AA amyloidosis.

Renal oxygenation and hemodynamics in acute kidney injury and chronic kidney disease

Summary 1. Acute kidney injury (AKI) puts a major burden on health systems that may arise from multiple initiating insults, including ischemia-reperfusion injury, cardiovascular surgery, radio-contrast administration as well as sepsis. Similarly, the incidence and prevalence of chronic kidney disease (CKD) continues to increase with significant morbidity and mortality. Moreover, an increasing number of AKI patients survive to develop CKD and end-stage kidney disease (ESRD). 2. Although the mechanisms for development of AKI and progression of CKD remain poorly understood, initial impairment of oxygen balance is likely to constitute a common pathway, causing renal tissue hypoxia and ATP starvation that will in turn induce extracellular matrix production, collagen deposition and fibrosis. Thus, possible future strategies for one or both conditions may involve dopamine, loop-diuretics, inducible nitric oxide synthase inhibitors and atrial natriuretic peptide, substances that target kidney oxygen consumption and regulators of renal oxygenation such as nitric oxide and heme oxygenase-1.

Prenatal programming-effects on blood pressure and renal function.

Impaired intrauterine nephrogenesis-most clearly illustrated by low nephron number-is frequently associated with low birthweight and has been recognized as a powerful risk factor for renal disease; it increases the risks of low glomerular filtration rate, of more rapid progression of primary kidney disease, and of increased incidence of chronic kidney disease or end-stage renal disease. Another important consequence of impaired nephrogenesis is hypertension, which further amplifies the risk of onset and progression of kidney disease. Hypertension is associated with low nephron numbers in white individuals, but the association is not universal and is not seen in individuals of African origin. The derangement of intrauterine kidney development is an example of a more general principle that illustrates the paradigm of plasticity during development-that is, that transcription of the genetic code is modified by epigenetic factors (as has increasingly been documented). This Review outlines the concept of prenatal programming and, in particular, describes its role in kidney disease and hypertension.

Renin-Angiotensin-Aldosterone System Blockade in Diabetic Nephropathy. Present Evidences

PubMed Central

Lozano-Maneiro, Luz; Puente-García, Adriana

2015-01-01

Diabetic Kidney Disease (DKD) is the leading cause of chronic kidney disease in developed countries and its prevalence has increased dramatically in the past few decades. These patients are at an increased risk for premature death, cardiovascular disease, and other severe illnesses that result in frequent hospitalizations and increased health-care utilization. Although much progress has been made in slowing the progression of diabetic nephropathy, renal dysfunction and the development of end-stage renal disease remain major concerns in diabetes. Dysregulation of the renin-angiotensin-aldosterone system (RAAS) results in progressive renal damage. RAAS blockade is the cornerstone of treatment of DKD, with proven efficacy in many arenas. The theoretically-attractive option of combining these medications that target different points in the pathway, potentially offering a more complete RAAS blockade, has also been tested in clinical trials, but long-term outcomes were disappointing. This review examines the “state of play” for RAAS blockade in DKD, dual blockade of various combinations, and a perspective on its benefits and potential risks. PMID:26569322

Highlights: Black-Right-Pointing-Pointer We induced renal lineages from mESCs by following the in vivo developmental cues. Black-Right-Pointing-Pointer We induced nephrogenic intermediate mesoderm by stepwise addition of factors. Black-Right-Pointing-Pointer We induced two types of renal progenitor cells by reciprocal conditioned media. Black-Right-Pointing-Pointer We propose the potential role of CD24 for the enrichment of renal lineage cells. -- Abstract: The in vitro derivation of renal lineage progenitor cells is essential for renal cell therapy and regeneration. Despite extensive studies in the past, a protocol for renal lineage induction from embryonic stem cells remains unestablished. In this study, we aimed to induce renal lineagesmore » from mouse embryonic stem cells (mESC) by following in vivo developmental stages, i.e., the induction of mesoderm (Stage I), intermediate mesoderm (Stage II) and renal lineages (Stage III). For stage I induction, in accordance with known signaling pathways involved in mesoderm development in vivo, i.e., Nodal, bone morphogenic proteins (BMPs) and Wnt, we found that the sequential addition of three factors, i.e., Activin-A (A), a surrogate for Nodal signaling, during days 0-2, A plus BMP-4 (4) during days 2-4, and A4 plus lithium (L), a surrogate for Wnt signaling, during days 4-6, was most effective to induce the mesodermal marker, Brachyury. For stage II induction, the addition of retinoic acid (R) in the continuous presence of A4L during days 6-8 was most effective to induce nephrogenic intermediate mesodermal markers, such as Pax2 and Lim1. Under this condition, more than 30% of cells were stained positive for Pax2, and there was a concomitant decrease in the expression of non-mesodermal markers. For stage III induction, in resemblance to the reciprocal induction between ureteric bud (UB) and metanephric mesenchyme (MM) during kidney development, we found that the exposure to conditioned media derived from UB and MM cells was effective in inducing MM and UB markers, respectively. We also observed the emergence and gradual increase of cell populations expressing progenitor cell marker CD24 from Stage I to Stage III. These CD24{sup +} cells correlated with higher levels of expression of Brachyury at stage I, Pax2 and Lim1 at stage II and MM markers, such as WT1 and Cadherin 11, after exposure to UB-conditioned media at stage III. In conclusion, our results show that stepwise induction by tracing in vivo developmental stages was effective to generate renal lineage progenitor cells from mESC, and CD24 may serve as a useful surface marker for renal lineage cells at stage II and MM cells at stage III.« less

Diagnosis of rare inherited glyoxalate metabolic disorders through in-situ analysis of renal stones

NASA Astrophysics Data System (ADS)

2012-04-01

The primary hyperoxalurias type I - III constitute rare autosomal-recessive inherited disorders of the human glyoxylate metabolism. By mechanisms that are ill understood progressive nephrocalcinosis and recurrent urolithiasis (kidney stone formation) often starting in early childhood, along with their secondary complications results in loss of nephron mass which progresses to end-stage renal failure over time. In the most frequent form, end-stage renal failure (ESRF) is the rule and combined liver/kidney transplantation respectively pre-emptive liver transplantation are the only causative treatment today. Hence, this contributes significantly to healthcare costs and early diagnosis is extremely important for a positive outcome for the patient. We are developing a stone-based diagnostic method by in-detail multi-methods investigation of the crystalline moiety in concert with urine and stone proteomics. Stone analysis will allow faster analysis at low-impact for the patients in the early stages of the disease. First results from combined spectroscopic (Raman, FTIR)and geochemical micro-analyses (Electron Microprobe and Laser Ablation ICP-MS) are presented here that show significant differences between stones from hyperoxaluria patients and those formed by patients without this disorder (idiopathic stones). Major differences exist in chemistry as well as in morphology and phase composition of the stones. Ca/P ratios and Mg contents differentiate between oxalate-stones from hyperoxaluria patients and idiopathic stones. Results show that also within the different subtypes of primary hyperoxaluria significant differences can be found in stone composition. These imply differences in stone formation which could be exploited for new therapeutic pathways. Furthermore, the results provide important feedback for suspected but yet unconfirmed cases of primary hyperoxaluria when used in concert with the genetic methods routinely applied.

Capillary haemangiomas are relatively common tumours, typically occurring in the subcutaneous tissue during childhood. However, visceral occurrence is very rare. These tumours make up a subset of vascular lesions that have previously, although rarely, been described in case reports in association with the kidney. Here we review the literature and describe a capillary haemangioma occurring in the renal hilum found to be coexistent with end-stage renal disease, renal cell carcinoma and polycythaemia. To our knowledge, this is the first case report to describe the occurrence of this tumour in the renal hilum in association with this constitution of renal pathologies. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Pauling, M; Lee, J C; Serpell, J W; Wilson, S

2017-05-01

We evaluated the incidence of perioperative hyperkalaemia in end-stage renal disease (ESRD) patients undergoing parathyroidectomy and investigated possible contributors to this phenomenon. This was a retrospective cohort study looking at patients who had undergone parathyroidectomy for chronic kidney disease-associated mineral bone disease (CKD-MBD) at The Alfred Hospital, Melbourne, since 2001. Baseline demographics including age, gender, aetiology of renal failure and mode of renal replacement therapy as well as anaesthetic technique and duration of surgery were studied as possible contributors. Perioperative potassium values were compared to preoperative baseline. Following stratification into normokalaemic and hyperkalaemic groups, demographic and operative data were compared. Twenty-two patients met the inclusion criteria with a median (interquartile range, IQR) age of 48.5 (42-59) years. There was a male predominance of 68%. The median (IQR) surgical time was 131 (115-164) minutes. Potassium levels rose perioperatively, with a 27.3% incidence of perioperative hyperkalaemia. Median duration of surgery was longer in the hyperkalaemic patients (167 minutes versus 125 minutes). Following the withdrawal of cinacalcet, parathyroidectomy is increasingly required in ESRD patients with CKD-MBD. Potentially life-threatening hyperkalaemia poses a significant risk in the perioperative period. Serial electrolyte monitoring is crucial to safety in this patient group. A multidisciplinary approach to perioperative management is required to ensure optimal timing of renal replacement therapy and appropriate means of serial blood sampling.

Defining end-stage renal disease in clinical trials: a framework for adjudication.

PubMed

Agarwal, Rajiv

2016-06-01

Unlike definition of stroke and myocardial infarction, there is no uniformly agreed upon definition to adjudicate end-stage renal disease (ESRD). ESRD remains the most unambiguous and clinically relevant end point for clinical trialists, regulators, payers and patients with chronic kidney disease. The prescription of dialysis to patients with advanced chronic kidney disease is subjective and great variations exist among physicians and countries. Given the difficulties in diagnosing ESRD, the presence of estimated GFR <15 mL/min/1.7 3m(2) itself has been suggested as an end point. However, this definition is still a surrogate since many patients may live years without being symptomatic or needing dialysis. The purpose of this report is to describe a framework to define when the kidney function ends and when ESRD can be adjudicated. Discussed in this report are (i) the importance of diagnosing symptomatic uremia or advanced asymptomatic uremia thus establishing the need for dialysis; (ii) establishing the chronicity of dialysis so as to distinguish it from acute dialysis; (iii) establishing ESRD when dialysis is unavailable, refused or considered futile and (iv) the adjudication process. Several challenges and ambiguities that emerge in clinical trials and their possible solutions are provided. The criteria proposed herein may help to standardize the definition of ESRD and reduce the variability in adjudicating the most important renal end point in clinical trials of chronic kidney disease.

This retrospective study summarizes 11 cases of end-stage renal disease (ESRD) in captive polar bears (Ursus maritimus) from eight zoologic institutions across the United States and Canada. Ten bears were female, one was male, and the mean age at the time of death was 24 yr old. The most common clinical signs were lethargy, inappetence, and polyuria-polydipsia. Biochemical findings included azotemia, anemia, hyperphosphatemia, and isosthenuria. Histologic examination commonly showed glomerulonephropathies and interstitial fibrosis. Based on submissions to a private diagnostic institution over a 16-yr period, ESRD was the most commonly diagnosed cause of death or euthanasia in captive polar bears in the United States, with an estimated prevalence of over 20%. Further research is needed to discern the etiology of this apparently common disease of captive polar bears.

Evolution of Cardiovascular Disease During the Transition to End-Stage Renal Disease.

2017-03-01

Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality in patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD). The rate of death in incident dialysis patients remains high. This has led to interest in the study of the evolution of CVD during the critical transition period from CKD to ESRD. Understanding the natural history and risk factors of clinical and subclinical CVD during this transition may help guide the timing of appropriate CVD therapies to improve outcomes in patients with kidney disease. This review provides an overview of the epidemiology of subclinical and clinical CVD during the transition from CKD to ESRD and discusses clinical trials of CVD therapies to mitigate risk of CVD in CKD and ESRD patients.

To evaluate whether ceramic workers exposed to silica experience an excess of end stage renal disease. On the basis of a health surveillance programme, a cohort of 2980 male ceramic workers has been enrolled during the period 1974-91 in Civitacastellana, Lazio, Italy. For each worker, employment history, smoking data, and x ray film readings were available. The vital status was ascertained for all cohort members. All 2820 people still alive and resident in the Lazio region as in June 1994 were searched for a match in the regional end stage renal diseases registry, which records (since June, 1994) all patients undergoing dialysis treatment in public and private facilities of the region. Expected numbers of prevalent cases from the cohort were computed by applying the rate of patients on dialysis treatment by the age distribution of the cohort. A total of six cases was detected when 1.87 were expected (observed/expected (O/E) = 3.21; 95% confidence interval (95% CI) 1.17 to 6.98). The excess risk was present among non-smokers (O = 2; O/E = 4.34) and smokers (O = 4; O/E = 2.83), as well as among workers without silicosis (O = 4; O/E = 2.78) and workers with silicosis (O = 2; O/E = 4.54). The risk was higher among subjects with < 20 years since first employment (O = 4; O/E = 4.65) than among those employed > 20 years. These results provide further evidence that exposure to silica dust among ceramic workers is associated with nephrotoxic effects.

Over the past decade, the number of patients on dialysis and with cardiovascular diseases has steadily increased. This retrospective analysis compares the postoperative mortality after cardiac surgery between patients on hemodialysis and peritoneal dialysis. Between 1998 and 2015, 136 patients with end-stage renal disease initiating dialysis more than one month before surgery underwent cardiac surgery. Demographics, preoperative hemodynamic and biochemical data were collected from the patient records. Vital status and date of death was retrieved from a national register. Hemodialysis was undertaken in 73% and peritoneal dialysis in 22% of patients aged 59.7 ± 12.9 years, mean EuroSCORE 8.6% ± 3.5. Isolated coronary artery bypass graft was performed in 46%, isolated valve procedure in 29% and combined procedures in 24% with no significant statistical difference between groups. The 30-day mortality was 14% for hemodialysis patients and 3% for peritoneal dialysis patients (p = .056). One-year and 5-year mortality were, 30% and 59% in the hemodialysis group, 30% and 57% in the peritoneal dialysis group (p = .975, p = .852). Independent predictors of total mortality were age (p = .001), diabetes (p = .017) and active endocarditis (p = .012). No statistically significant difference in mortality was found between patients in hemo- or peritoneal dialysis. However, we observed that patients with end-stage renal disease on dialysis have two times higher mortality rate than estimated by EuroSCORE.

Whether low-level exposure to lead may give rise to chronic kidney disease or end-stage renal disease (ESRD) is debated. In this study, we aimed to specifically investigate if low-level occupational exposure to lead was associated with increased incidence of ESRD. The incidence of starting renal replacement therapy as a result of ESRD was examined in a cohort of10 303 lead-workers who had controlled blood lead concentrations due to a compulsory occupational health surveillance programme in Sweden during the time period 1977-1990. The ESRD incidence (obtained through register-linkage) among the lead-exposed workers was compared with the age, sex and calendar period-adjusted expected incidence based on data from the Swedish renal registry. Dose-response association was evaluated in external (general population) and internal (within the occupational cohort) comparisons by highest achieved blood lead level. There were 30 (0.29%) individuals in the cohort who developed ESRD during the median follow-up period of 26.3 years. The standardised incidence ratio (SIR) for ESRD incidence was 0.79 (95% CI 0.54 to 1.13). Among those who achieved the highest blood lead (>41.4 µg/dL), the SIR was 1.01 (0.44 to 1.99). There was no evidence of a dose-response relationship between the maximum achieved blood lead or the cumulative blood lead exposure and ESRD in external or internal comparisons. This study of workers with documented occupational lead exposures followed for 20 years shows no statistically significant association between lead exposure (following the current occupational recommendations for Sweden) and ESRD.

Hydrocarbon exposure may cause glomerulonephritis and worsen renal function: evidence based on Hill's criteria for causality.

PubMed

Ravnskov, U

2000-08-01

Many observational and experimental studies point to hydrocarbon exposure as an important pathogenic factor in glomerulonephritis. The findings have made little impact on current concepts and patient care, possibly because the hypothesis of a direct causal effect of the exposure and the hypothesis that the exposure worsens renal function have not been considered separately. This review examines these two hypotheses using Hill's criteria for causality. The results from 14 cross-sectional, 18 case-control studies, two cohort studies, 15 experiments on laboratory animals and two on human beings together with many case reports satisfy all but one of Hill's criteria for both hypotheses. Of particular importance is the finding in the case-control and follow-up studies of an association between degree of exposure and stage of renal disease, and an inverse association between degree of exposure and renal function, indicating that the most important effect of hydrocarbon exposure is its effect on renal function. End-stage renal failure may be preventable in many patients with glomerulonephritis provided a possible exposure to toxic chemicals is discontinued.

Pregnancy in women with renal disease. Yes or no?

2011-01-01

Women with renal disease who conceive and continue pregnancy, are at significant risk for adverse maternal and fetal outcomes. Although advances in antenatal and neonatal care continue to improve these outcomes, the risks remain proportionate to the degree of underlying renal dysfunction. The aim of this article, is to examine the impact of varying degrees of renal insufficiency on pregnancy outcome, in women with chronic renal disease and to provide if possible, useful conclusions whether and when, a woman with Chronic Kidney Disease (CKD), should decide to get pregnant. This article, reviews briefly the normal physiological changes of renal function during pregnancy, and make an attempt to clarify the nature and severity of the risks, in the settings of chronic renal insufficiency and end stage renal disease, including dialysis patients and transplant recipients.

Renal artery stenosis (RAS) is frequently associated with severe comorbidities such as reduced renal perfusion, hypertension, and end-stage renal failure. In approximately 90% of patients, renal artery atherosclerosis is the main cause for RAS, and it is associated with an increased risk for fatal and non-fatal cardiovascular and renal complications. Endovascular management of atherosclerotic RAS (ARAS) has been recently evaluated by several randomized controlled trials that failed to demonstrate benefit of stenting. Furthermore, the Cardiovascular Outcomes in Renal Atherosclerotic Lesions study did not demonstrate any benefit over the revascularization approach. In this review, we summarized the available data from retrospective, prospective and randomized trials on ARAS to provide clinicians with sufficient data in order to produce useful conclusions for everyday clinical practice.

End-stage of chronic renal failure (CRF) is frequently associated with cardiac and vascular comorbidities requiring cardiosurgical interventions. Over 9 years, from 2000 to 2009, the A. N. Bakulev Research Center of Cardiovascular Surgery, Russian Academy of Medical Sciences, delivered cardiosurgical care to 16 patients aged 20 to 74 years with end-stage CRF. The duration of programmed hemodialysis was 1 to 102 months. The preoperative patient preparation protocol comprised correction of anemia, hypoproteinemia, hypertension, and water-electrolyte and acid-base balances. Five patients underwent endovascular myocardial revascularization; open heart surgery was performed in one patient. Interventions under extracorporeal circulation were made in 10 other patients. Ultrafiltration was intraoperatively carried out. On-line hemodiafiltration was performed following coronary artery stenting. After open operations, renal replacement therapy (first hemodiafiltration, then hemodialysis) as daily sessions was initiated on day 2 and, when the patients were transferred to intensive care units, it was performed by the programmed hemodialysis protocol. There were no fatal outcomes at the follow-up. The key aspects of treatment success achievement and improved quality of life in patients on programmed hemodialysis are the detection of cardiovascular diseases requiring surgery, the timely referral of the patients to a cardiosurgical hospital, the meticulous pre- and perioperative management (correction of anemia, hypoproteinemia, water-electrolyte balance, use of ultrafiltration and the adequate rate of perfusion at the stage of extracorporeal circulation, and daily renal replacement therapy in the postoperative period), and continuity in the work of all specialists.

Evolution of IgA nephropathy into anaphylactoid purpura in six cases--further evidence that IgA nephropathy and Henoch-Schonlein purpura nephritis share common pathogenesis.

As the morphological and immunohistochemical manifestations of immunoglobulin A (IgA) nephropathy and Henoch-Schonlein purpura nephritis (HSPN) are very similar, they are considered to share a common pathogenesis. Although HSPN usually develops after the appearance of anaphylactoid purpura, we have encountered patients whose renal symptoms preceded purpura. We reviewed the clinical courses of patients who were first diagnosed with IgA nephropathy, but developed purpura later, at the National Center for Child Health and Development in Tokyo, Japan. Of the 53 patients who were diagnosed with primary IgA nephropathy at our institute during the study period (March 2002 to July 2015), six (11 %) developed anaphylactoid purpura after the diagnosis of primary IgA nephropathy and therefore met the inclusion criteria. Duration between the onset of nephritis and subsequent appearance of purpura ranged from 5 months to 14 years. One patient reached end-stage renal failure due to IgA nephropathy and developed purpura after renal transplantation. All renal biopsies performed before the appearance of purpura showed mesangial proliferation with predominant IgA deposits. Urinary findings deteriorated in three patients after the appearance of purpura, including one patient who developed rapidly progressive glomerulonephritis. Renal biopsy findings worsened in two patients. At the last observation, two patients showed mild renal insufficiency. Our clinical experience and previous reports support the argument that IgA nephropathy and HSPN are different manifestations of a single disease. Hence, it is acceptable to consider that they are variants of a single disease.

Influence of various factors on the accuracy of gallium-67 imaging for occult infection

To examine whether the results and interpretation of gallium-67 citrate imaging may be adversely influenced by factors present in compromised patients, we reviewed our 1-year experience in 69 patients in intensive care units, renal transplants, and those on hemodialysis. Our results indicate that it is an inappropriate diagnostic procedure for acute pancreatitis since seven of nine had false-negative results. Using loglinear modeling and chi-square analysis we found that treatment with antiinflammatory steroids, severe liver disease, end-stage renal disease, and renal transplantation with immunosuppressive therapy did not interfere with gallium-67 uptake. Increased rate of true-negative results in patients with end-stage renalmore » disease was due to a greater and earlier use of the test in the febrile transplant patient and in hemodialysis patients with infections not amenable to diagnosis with gallium-67 scan (transient bacteremia and bacteriuria). We conclude that gallium-67 imaging is a useful diagnostic tool that, with the exception of acute pancreatitis, has very few false-negative results.« less

Nutritional status, functional capacity and exercise rehabilitation in end-stage renal disease.

PubMed

Mercer, T H; Koufaki, P; Naish, P F

2004-05-01

A significant percentage of patients with end-stage renal disease are malnourished and/or muscle wasted. Uremia is associated with decreased protein synthesis and increased protein degradation. Fortunately, nutritional status has been shown to be a modifiable risk factor in the dialysis population. It has long been proposed that exercise could positively alter the protein synthesis-degradation balance. Resistance training had been considered as the only form of exercise likely to induce anabolism in renal failure patients. However, a small, but growing, body of evidence indicates that for some dialysis patients, favourable improvements in muscle atrophy and fibre hypertrophy can be achieved via predominantly aerobic exercise training. Moreover, some studies tentatively suggest that nutritional status, as measured by SGA, can also be modestly improved by modes and patterns of exercise training that have been shown to also increase muscle fibre cross-sectional area and improve functional capacity. Functional capacity tests can augment the information content of basic nutritional status assessments of dialysis patients and as such are recommended for routine inclusion as a feature of all nutritional status assessments.

Urgent-Start Peritoneal Dialysis: A Chance for a New Beginning

2014-01-01

Peritoneal dialysis (PD) remains greatly underutilized in the United States despite the widespread preference of home modalities among nephrologists and patients. A hemodialysis-centric model of end-stage renal disease care has perpetuated for decades due to a complex set of factors, including late end-stage renal disease referrals and patients who present to the hospital requiring urgent renal replacement therapy. In such situations, PD rarely is a consideration and patients are dialyzed through a central venous catheter, a practice associated with high infection and mortality rates. Recently, the term urgent-start PD has gained momentum across the nephrology community and has begun to change this status quo. It allows for expedited placement of a PD catheter and initiation of PD therapy within days. Several published case reports, abstracts, and poster presentations at national meetings have documented the initial success of urgent-start PD programs. From a wide experiential base, we discuss the multifaceted issues related to urgent-start PD implementation, methods to overcome barriers to therapy, and the potential impact of this technique to change the existing dialysis paradigm.

The incidence of end-stage renal disease in children is increasing. Peritoneal dialysis (PD) is the modality of choice in many European countries and is increasingly applied worldwide. PD enables children of all ages to be successfully treated while awaiting the ultimate goal of renal transplantation. The advantages of PD over other forms of renal replacement therapy are numerous, in particular the potential for the child to lead a relatively normal life. Indications for commencing PD, the rationale, preparation of family, technical aspects, and management of complications are discussed. PMID:26504404

We determined the insertion/deletion (I/D) polymorphism of the angiotensin-coverting enzyme (ACE) gene in a multicenter trial of ethnically homogeneous Japanese type 2 diabetes mellitus (DM) patients. All patients (n = 748) were divided into 5 groups as follows: group I (normoalbuminuric patients), group II (microalbuminuric patients), group III (overt albuminuric patients with serum creatinine (s-Cr) levels of less than 1.2 mg/dl), group IV (overt albuminuric patients with s-Cr levels of more than 1.3 mg/dl but excluding hemodialysis patients), and group V (hemodialysis patients). We selected patients with a diabetic duration of more than 15 years in the mild stage (groups I and II), but placed no limits on those in the advanced and end-stages (groups III, IV and V). The frequency of the DD genotype was slightly higher in the advanced and end stages. The frequency of the DD genotype in the mild stage differed from that in the end stage (II/ID/DD 47.8%/41.0%/11.2% vs. 37.0 %/43.3%/19.7% p = 0.07, II + ID/DD 88.8%/11.2% vs. 80.3%/19.7%, p < 0.05). D allele frequency in the mild stage also differed from that in the end stage (I/D 68.3%/31.7% vs. 58.7%/41.3%, p < 0.02). The presence of the DD genotype increased the risk of end-stage renal disease (ESRD) more than that of the other genotypes (odds ratio ID/II = 1.37, 95% CI 0.82-2.27; DD/II = 2.27, 95% CI 1.12-4.61). It appears that the DD genotype is associated with progression of Japanese type 2 diabetic nephropathy.

Wiesholzer, Martin

2013-06-01

The number of elderly patients with end stage renal disease is constantly increasing. Conventional hämodiaylsis as the mainstay of renal replacement therapy is often poorly tolerated by frail eldery patients with multiple comorbidities. Although many of these patients would prefer a home based dialysis treatment, the number of elderly patients using peritoneal dialysis (PD) is still low. Impaired physical and cognitive function often generates insurmountable barriers for self care peritoneal dialysis. Assisted peritoneal dialysis can overcome many of these barriers and give elderly patients the ability of a renal replacement therapy in their own homes respecting their needs.

Residual Renal Function in Children Treated with Chronic Peritoneal Dialysis

PubMed Central

Roszkowska-Blaim, Maria

2013-01-01

Residual renal function (RRF) in patients with end-stage renal disease (ESRD) receiving renal replacement therapy is defined as the ability of native kidneys to eliminate water and uremic toxins. Preserved RRF improves survival and quality of life in adult ESRD patients treated with peritoneal dialysis. In children, RRF was shown not only to help preserve adequacy of renal replacement therapy but also to accelerate growth rate, improve nutrition and blood pressure control, reduce the risk of adverse myocardial changes, facilitate treatment of anemia and calcium-phosphorus balance abnormalities, and result in reduced serum and dialysate fluid levels of advanced glycation end-products. Factors contributing to RRF loss in children treated with peritoneal dialysis include the underlying renal disease such as hemolytic-uremic syndrome and hereditary nephropathy, small urine volume, severe proteinuria at the initiation of renal replacement therapy, and hypertension. Several approaches can be suggested to decrease the rate of RRF loss in pediatric patients treated with chronic peritoneal dialysis: potentially nephrotoxic drugs (e.g., aminoglycosides), episodes of hypotension, and uncontrolled hypertension should be avoided, urinary tract infections should be treated promptly, and loop diuretics may be used to increase salt and water excretion.

To explore the experiences of Korean patients with end-stage renal disease awaiting kidney transplantation. The need for kidney transplantation has increased worldwide, while the number of kidney donors has not increased commensurately. This mismatch is a serious issue in South Korea. Prolonged waits for transplantation may cause physical and psychosocial issues and lead to poor outcomes. Nevertheless, the experience of waiting for kidney transplantation in South Korea has never been explored in depth. A qualitative descriptive design was used. The participants were eight patients diagnosed with end-stage renal disease on the waiting list for kidney transplantation in South Korea. Data were collected through individual in-depth interviews. All conversations during interviews were recorded and transcribed verbatim. Transcribed data were analysed using conventional content analysis. The experience of waiting for kidney transplantation consisted of six categories: (1) the light at the end of the tunnel, (2) being on call without any promise, (3) a tough tug of war between excitement and frustration, (4) doubts in the complexity, (5) A companion on the hard journey and (6) getting ready for D-day. Kidney transplantation candidates experience psychosocial difficulties and concerns while waiting for long periods of time without any assurance of resolution. Systematic education and psychosocial support from health care professionals and family members help patients get through what they describe as a difficult journey. Comprehensive management programs for kidney transplantation candidates are needed. Health care professionals need to recognise the psychosocial concerns of patients awaiting kidney transplantation. Clinicians should provide patients with information and support throughout the waiting period. © 2016 John Wiley & Sons Ltd.

Cytokines play a critical role in the pathophysiology of end stage renal disease (ESRD). Tumour necrosis factor-a (TNF-α) is an important cytokine involved in initiation and progression of renal diseases. The present study evaluated the association of specific alleles/genotype of TNF-α with chronic renal failure (CRF) and ESRD. A total of 30 CRF patients who were not on renal replacement therapy, 85 ESRD patients and 120 healthy controls were included in the study. The ESRD patients belonged to two subgroups: patients on peritoneal dialysis (PD) without peritonitis (n = 50) and with peritonitis (n = 35). TNF-α genotype (-308 G > A) was determined by polymerase chain reaction-restriction fragment length polymorphism. Level of TNF-α was detected in the sera of patients and healthy controls by enzyme linked immunosorbent assay (ELISA), and also in the dialysate of patients on PD. The genotypic distributions of TNF-α (-308 G > A) were significantly different between patients and controls. Homozygous A/A genotype had significant association with CRF and ESRD (P < 0.001, odds ratio [OR] = 25.02). Frequency of homozygous A/A genotype was significantly higher in all subgroups of patients than controls (CRF 40% vs control 2.5%, P = 0.001; PD 54% vs control 2.5%, P < 0.001 and PD with peritonitis 62.8% vs control 2.5%, P < 0.001). Patients with homozygous A/A genotype had significantly elevated levels of TNF-α in the sera of patients and in the dialysate of PD patients. Individuals with homozygous TNF-α (-308 G > A) polymorphisms has significant association with CRF and ESRD, and thus may be a predictor for development of the disease. Elevated TNF-α may be a contributory factor. © 2015 Asian Pacific Society of Nephrology.

The long-term risk associated with childhood kidney disease that had not progressed to chronic kidney disease in childhood is unclear. We aimed to estimate the risk of future end-stage renal disease (ESRD) among adolescents who had normal renal function and a history of childhood kidney disease. We conducted a nationwide, population-based, historical cohort study of 1,521,501 Israeli adolescents who were examined before compulsory military service in 1967 through 1997; data were linked to the Israeli ESRD registry. Kidney diseases in childhood included congenital anomalies of the kidney and urinary tract, pyelonephritis, and glomerular disease; all participants included in the primary analysis had normal renal function and no hypertension in adolescence. Cox proportional-hazards models were used to estimate the hazard ratio for ESRD associated with a history of childhood kidney disease. During 30 years of follow-up, ESRD developed in 2490 persons. A history of any childhood kidney disease was associated with a hazard ratio for ESRD of 4.19 (95% confidence interval [CI], 3.52 to 4.99). The associations between each diagnosis of kidney disease in childhood (congenital anomalies of the kidney and urinary tract, pyelonephritis, and glomerular disease) and the risk of ESRD in adulthood were similar in magnitude (multivariable-adjusted hazard ratios of 5.19 [95% CI, 3.41 to 7.90], 4.03 [95% CI, 3.16 to 5.14], and 3.85 [95% CI, 2.77 to 5.36], respectively). A history of kidney disease in childhood was associated with younger age at the onset of ESRD (hazard ratio for ESRD among adults <40 years of age, 10.40 [95% CI, 7.96 to 13.59]). A history of clinically evident kidney disease in childhood, even if renal function was apparently normal in adolescence, was associated with a significantly increased risk of ESRD, which suggests that kidney injury or structural abnormality in childhood has long-term consequences.

Background Pesticide exposure has been found to cause renal damage and dysfunction in experimental studies, but epidemiological research on the renal effects of chronic low-level pesticide exposure is limited. We investigated the relationships between end-stage renal disease (ESRD) among wives of licensed pesticide applicators (N = 31,142) in the Agricultural Health Study (AHS) and (1) personal pesticide use, (2) exposure to the husband's pesticide use, and (3) other pesticide-associated farming and household activities. Methods AHS participants reported pesticide exposure via self-administered questionnaires at enrollment (1993–1997). ESRD cases were identified via linkage to the United States Renal Data System. Associations between ESRD and pesticide exposures were estimated with Cox proportional hazard regression models controlling for age at enrollment. Models of associations with farming and household factors were additionally adjusted for personal use of pesticides. Results We identified 98 ESRD cases diagnosed between enrollment and 31 December 2011. Although women who ever applied pesticides (56% of cohort) were less likely than those who did not apply to develop ESRD (Hazard Ratio (HR): 0.42; 95% CI: 0.28, 0.64), among women who did apply pesticides, the rate of ESRD was significantly elevated among those who reported the highest (vs. lowest) cumulative general pesticide use (HR: 4.22; 95% CI: 1.26, 14.20). Among wives who never applied pesticides, ESRD was associated with husbands' ever use of paraquat (HR = 1.99; 95% CI: 1.14, 3.47) and butylate (HR = 1.71; 95% CI: 1.00, 2.95), with a positive exposure–response pattern for husband’s cumulative use of these pesticides. Conclusions ESRD may be associated with direct and/or indirect exposure to pesticides among farm women. Future studies should evaluate indirect exposure risk among other rural populations.

Non-proteinuric rather than proteinuric renal diseases are the leading cause of end-stage kidney disease.

Proteinuria is a distinguishing feature in primary and secondary forms of chronic glomerulonephritis, which contribute to no more than the 20% of the end-stage kidney disease (ESKD) population. The contribution of non-proteinuric nephropathies to the global ESKD burden is still poorly focused and scarce research efforts are dedicated to the elucidation of risk factors and mechanistic pathways triggering ESKD in these diseases. We abstracted information on proteinuria in the main renal diseases other than glomerulonephritides that may evolve into ESKD. In type 2 diabetes, non-proteinuric diabetic kidney disease (DKD) is more frequent than proteinuric DKD, and risk factors for non-proteinuric forms of DKD now receive increasing attention. Similarly, proteinuria is most often inconspicuous or absent in the most frequent cause of ESKD, i.e. hypertension-related chronic kidney disease (CKD), as well as in progressive cystic diseases like autosomal dominant polycystic kidney disease and in pyelonephritis/tubulo-interstitial diseases. Maintaining a high degree of attention in the care of CKD patients with proteinuria is fundamental to effectively retard progression toward kidney failure. However, substantial research efforts are still needed to develop treatment strategies that may help the vast majority of CKD patients who eventually develop ESKD via mechanistic pathways other than proteinuria. © The Author 2017.

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

End stage renal disease in Brunei Darussalam - report from the first Brunei Dialysis Transplant Registry (BDTR).

The Brunei Dialysis and Transplant Registry (BDTR) was established in 2011 to collect data from patients undergoing renal replacement therapy (RRT) in Brunei Darussalam. The chief aims of the registry are to obtain general demographic data for RRT patients and to determine disease burden attributable to End Stage Renal Disease (ESRD). The registry population comprises of all ESRD patients treated in Brunei Darussalam. Data domains include general demographic data, medical history, ESRD etiological causes, laboratory investigations, dialysis treatment and outcomes. There were 545 prevalent RRT patients in Brunei at the end of 2011. The incidence and prevalence of ESRD were 265 and 1250 per million population. Hemodialysis (HD), Peritoneal Dialysis (PD) and Transplant comprised of 83%, 11% and 6% of the RRT population, respectively. Diabetes mellitus accounted for 57% of all new incident cases. The mean serum hemoglobin, phosphate, calcium and iPTH were 11.0 ± 1.6 g/dL, 1.9 ± 0.5 mmol/L, 2.3 ± 0.2 mmol/L and 202.5 ± 323.4 ng/mL. Dialysis adequacy for HD and PD were 65.1 (urea reduction ratio) and 2.0 ± 0.3 (Kt/v). 71 % of all prevalent HD had functioning AV fistulae and the peritonitis incidence was one in 24.5 patient-month/episode. The first BDTR has identified some deficiencies in the renal services in Brunei. However, it signals an important milestone for the establishment of benchmarked renal practice in the country. We hoped to maintain and improve our registry for years to come and will strive to align our standards to acceptable international practice.

Targeting glucagon receptor signalling in treating metabolic syndrome and renal injury in Type 2 diabetes: theory versus promise.

PubMed

Li, Xiao C; Zhuo, Jia L

2007-08-01

Pancreatic bi-hormones insulin and glucagon are the Yin and Yang in the regulation of glucose metabolism and homoeostasis. Insulin is synthesized primarily by pancreatic beta-cells and is released in response to an increase in blood glucose levels (hyperglycaemia). By contrast, glucagon is synthesized by pancreatic alpha-cells and is released in response to a decrease in blood glucose (hypoglycaemia). The principal role of glucagon is to counter the actions of insulin on blood glucose homoeostasis, but it also has diverse non-hyperglycaemic actions. Although Type 1 diabetes is caused by insulin deficiency (insulin-dependent) and can be corrected by insulin replacement, Type 2 diabetes is a multifactorial disease and its treatment is not dependent on insulin therapy alone. Type 2 diabetes in humans is characterized by increased insulin resistance, increased fasting blood glucose, impaired glucose tolerance and the development of glomerular hyperfiltration and microalbuminuria, ultimately leading to diabetic nephropathy and end-stage renal disease. Clinical studies have suggested that an inappropriate increase in hyperglycaemic glucagon (hyperglucagonaemia) over hypoglycaemic insulin (not insulin deficiency until advanced stages) plays an important role in the pathogenesis of Type 2 diabetes. However, for decades, research efforts and resources have been devoted overwhelmingly to studying the role of insulin and insulin-replacement therapy. By contrast, the implication of glucagon and its receptor signalling in the development of Type 2 diabetic metabolic syndromes and end-organ injury has received little attention. The aim of this review is to examine the evidence as to whether glucagon and its receptor signalling play any role(s) in the pathogenesis of Type 2 diabetic renal injury, and to explore whether targeting glucagon receptor signalling remains only a theoretical antidiabetic strategy in Type 2 diabetes or may realize its promise in the future.

Risks and costs of end-stage renal disease after heart transplantation.

To estimate the risks and costs of end-stage renal disease (ESRD) after heart transplantation. Previous studies have shown high rates of ESRD among solid-organ transplant patients, but the relevance of these studies for current transplant practices and policies is unclear. Limitations of prior studies include relatively small, single-center samples and estimates made before implementing suggested practice changes to reduce ESRD risk. Medicare beneficiaries who underwent heart transplantation between 1989 and 1994 were eligible for study inclusion (n=2088). Thirty-four patients undergoing dialysis or who had the diagnosis of ESRD before or at transplantation were excluded from the study. ESRD was defined as any patient undergoing renal transplantation or requiring dialysis for more than 3 months. Mortality and ESRD events were recorded up to 1995. ESRD risk was estimated using the Kaplan-Meier product-limit estimator and logistic regression analyses. Linear regression was performed to determine expenditures for treating ESRD, and we developed long-term models of the risk and direct medical costs of ESRD care. The annual risk of ESRD was 0.37% in the first year after transplant and increased to 4.49% by the sixth posttransplant year. There was no significant trend in the risk of ESRD based on the year of transplantation, even after adjusting for patient characteristics. The average cumulative 10-year direct cost of ESRD per patient undergoing heart transplantation exceeded $13,000. In a large, national sample of patients undergoing heart transplantation, ESRD is not rare, even for patients undergoing transplant after the development of new practices intended to reduce its occurrence. ESRD remains an important component of the costs of heart transplantation.

Role of telehealth in renal replacement therapy education.

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.

To analyze the maternal and obstetric outcomes of patients with Alport syndrome. We describe the pregnancy course of 8 pregnancies of three family members with the autosomal dominant (the rarest) form of Alport syndrome. We also analyzed 10 previously reported pregnancies with other Alport mutations in order to explore risk factors for unfavorable obstetric outcomes and maternal renal deterioration. In 13 pregnancies (72 %), renal function did not deteriorate permanently. All of these women had pre-pregnancy mild chronic kidney disease (CKD stage G1). In all of them, only a transient increase in proteinuria was recorded and in one case there was a transient decrease in the estimated glomerular filtration rate. In four other pregnancies (22 %), renal function deteriorated following pregnancy. All of them were complicated with pre-eclampsia. One woman had pre-pregnancy CKD-G2A3 and chronic hypertension. Two women had CKD-G1A3 of whom one had pre-pregnancy proteinuria near the nephrotic range. In the fourth case, renal function deterioration was reported without information on the exact pre-pregnancy renal function. In the last case, CKD-G2 was reported after pregnancy without information on CKD stage prior to pregnancy. Severe proteinuria did not imply a permanent renal function deterioration if it developed during pregnancy. Ten pregnancies ended with preterm birth (56 %). Two stillbirths were reported (11 %); however, only one was attributed to maternal health deterioration. Data regarding pregnancy outcomes in Alport syndrome is limited. The outcome seems favorable when pre-pregnancy kidney function is normal or near normal and when chronic hypertension/pre-eclampsia is absent.

One-stage repair of aortic arch obstruction and associated cardiac anomalies is a surgical challenge in infants.The purpose of the present study is to review the current outcome using regional cerebral perfusion (RCP) during a procedure correcting interrupted aortic arch (IAA) and also isolated aortic coarctation (CoA) and CoA combined with hypoplastic aortic arch (CoA-HyAA) in our center. Between January 2007 and July 2008, 24 infant patients with interrupted aortic arch (IAA) (n=3), isolated aortic coarctation (iCoA) (n=9) and aortic coarctation with hypoplastic aortic arch (CoA-HyAA) (n=12) underwent one-stage surgical correction in our hospital. End-to-end anastomosis was employed in 12 infants (IAA n=3 and iCoA n=9); for the other 12 patients with CoA-HyAA, an end-to-end extended anastomosis was used in 8 cases, end-to-side anastomosis in 2 cases, and composite heterologous pericardial patch in 2 cases. RCP with 40 mL/kg/min through the innominate artery during aortic arch reconstruction was employed for all pediatric patients. One single-dose histidine-ketoglutarate-tryptophan (HTK) solution was used for myocardial protection during CPB. Cardiopulmonary bypass time and aortic cross-clamp time were 165.6+/-32.4 min and 81.7+/-30.0 min, respectively. The mean regional cerebral perfusion time was 31.0+/-10.6 min; lowest nasopharyngeal temperature was 19.1+/-1.1 degrees C. Operative mortality rate in both groups was 8.3%. Mean follow-up was 10.5+/-4.8 months. There was no late mortality or postoperative neurologic, renal or hepatic complications. All patients are asymptomatic and are developing normally. One-stage total arch repair using the RCP technique is an excellent method that may minimize neurologic and renal complications. Our surgical strategy for arch anomaly has a low rate of residual and recurrent coarctation when performed in these infants.

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 < 0.001). When the baseline CD4 count was below 200 cells/μL, the peritonitis rate rose to 3.69 episodes/person-years (HR 4.54, 95% CI 2.35-8.76, P < 0.001), while a baseline CD4 count above 350 cells/μL was associated with a 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 < 200 cells/μL (HR, 3.28; CI, 1.42-7.61; P = 0.006). Catheter failure rates were 0.34 (HIV-positive cohort) and 0.24 (HIV-negative cohort) episodes/person-years (HR, 1.42; 95% CI, 0.73-2.73; P = 0.299). 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. HIV infection in end-stage renal disease patients managed by CAPD was associated with increased peritonitis risk; however, HIV infection did not increase the risk for CAPD catheter failure rate at 18 months.

Renal involvement is a rare occurrence in juvenile rheumatoid arthritis (JRA). We report on two JRA patients with kidney disease. The first was a 14-year-old African-American female with a 12-month history of polyarthritis. On presentation she was found to have an ESR of 127 mm/h and a positive ANA, rheumatoid factor (RF), perinuclear antineutrophil cytoplasmic antibodies (pANCA), haematuria, proteinuria with normal BUN and creatinine. Renal biopsy showed focal segmental glomerulosclerosis. Her renal function deteriorated to end-stage renal failure requiring dialysis within a few months, despite aggressive treatment with steorids and monthly i.v. pulses of cyclophosphamide. The second patient presented with a 6-week history of polyarthritis and intermittent fever, and had a salmon-coloured evanescent rash. On presentation his laboratory evaluation was significant for elevated ESR and negative ANA, RF and ANCA tests. Within 8 months the patient had developed a persistent microscopic haematuria. Renal biopsy showed mild mesangial glomerulonephritis. On low-dose methotrexate therapy his JRA went into remission and his renal function remained normal. The haematuria persisted for 1 year and then resolved spontaneously. This is the first time that focal segmental glomerulosclerosis and mesangial glomerulonephritis have been described in JRA. Although the association may be just coincidental, further studies are needed to define the role of JRA in these renal conditions. In patients with JRA, urinalysis and renal function should be routinely monitored.

Cystinosis is a rare autosomal recessive disorder resulting from defective lysosomal transport of cystine due to mutations in the cystinosin lysosomal cystine transporter (CTNS) gene. The clinical phenotype of nephropathic cystinosis is characterized by renal tubular Fanconi syndrome and development of end-stage renal disease during the first decade. Although metabolic acidosis is the classically prominent finding of the disease, a few cases may present with hypokalemic metabolic alkalosis mimicking Bartter syndrome. Bartter-like presentation may lead to delay in diagnosis and initiation of specific treatment for cystinosis. We report a case of a 6-year-old girl initially presenting with the features of Bartter syndrome that was diagnosed 2 years later with nephropathic cystinosis and a novel CTNS mutation.

Applying disease management strategies to Medicare.

Medicare coverage begins for many when they have already developed one or more chronic diseases, and it often pays for the latest and costliest phases. Population-based disease modeling, patient screening, and monitoring would be appropriate interventions for chronic renal disease. Patients who have not yet advanced to end-stage renal disease would benefit from management of diabetes and hypertension, avoidance of nephrotoxic substances, and better preparation for dialysis. Administrative support could take the form of clinical guidelines, physician-led multidisciplinary teams, integrated delivery systems, provider and patient education, and new information technologies. Medicare reflects the long-term public perspective, and thus should further this new direction by supporting education, reimbursing for prevention efforts and allied health services, encouraging efficiency, and monitoring cost and quality outcomes.

A spontaneous pre-anastomotic occlusion does not necessarily impair forearm native dialysis fistulas: echo-Doppler, 3D MR angiographic and digital subtraction angiographic imaging.

Renal transplantation is the choice treatment of end-stage renal disease. When it is not indicated or not immediately feasible, hemodialysis must be performed, preferably via a native arteriovenous fistula in the forearm. A pre-anastomotic occlusion of this type of fistula is often accompanied by a thrombosis of its draining vein. In some instances, the venous segment may remain permeable thanks to the development of arterial collateral pathways and may even allow efficient dialysis without any clinical syndrome of distal steal. We present the echo-Doppler, magnetic and angiographic characteristics of three of these collateralized shunts that have remained functional, in one of the cases following a percutaneous dilation.

We analyzed the evolution in the Health Related Quality of Life (HRQOL) during the first year following renal transplant. Prospective and longitudinal study carried out with 28 patients who received a primary cadaveric renal transplant. The tests applied were a structured interview and SF-36, Euroqol- 5D (EQ-5D) Health Questionnaires and End-Stage Renal Disease Symptom Checklist- Transplantation Module (ESRD-SCL). With the course of time, the renal patients improve in four areas: physical ( and ), psychological ( and ), execution of daily tasks ( and ) and subjective perception of own state of health (). The HRQOL in renal transplant patients improves with the course of time.

A simulation model to investigate the impact of cardiovascular risk in renal transplantation.

McLean, D R; Jardine, A G

Premature cardiovascular (CV) disease is the leading cause of death following renal transplantation and, as a consequence of death with a functioning graft, it is a major cause of graft loss. Renal transplant recipients have a high prevalence of CV risk factors that influence both patient and graft survival. We used data on the relationship between CV risk factors and graft and patient survivals to develop a discrete event simulation model to study the possible impact of CV risk factor reduction on transplant outcome. The simulation was based on a renal unit in a population that has the risk factor profile of patients from the West of Scotland. We studied the dynamic between patient numbers on the waiting list compared to the transplanted list. After establishing results pertinent to the renal unit, we investigated in what way potential changes to transplant policy affected patient numbers. These perturbations included changing the number of transplants performed, changing the incidence of acute rejection, and interventional policies where patients on the waiting list were selectively transplanted taking into account their CV risk factor profiles. Overall, the model predicts that reducing CV risk in the population with end-stage renal failure awaiting kidney transplantation will have comparable benefits to foreseeable developments in immunosuppression or attainable increases in transplant numbers. Moreover, addressing CV risk has benefits for all patients regardless of whether or not they ultimately receive a kidney transplant.

The purpose of this study is to evaluate serum bicarbonate level as a risk factor for renal outcomes, cardiovascular events, and mortality in patients with chronic kidney disease (CKD). Observational cohort study. 3,939 participants with CKD stages 2-4 who enrolled in the Chronic Renal Insufficiency Cohort (CRIC) between June 2003 and December 2008. Serum bicarbonate level. Renal outcomes, defined as end-stage renal disease (either initiation of dialysis therapy or kidney transplantation) or 50% reduction in estimated glomerular filtration rate (eGFR); atherosclerotic events (myocardial infarction, stroke, or peripheral arterial disease); congestive heart failure events; and death. Time to event. Mean eGFR was 44.8 ± 16.8 (SD) mL/min/1.73 m(2), and median serum bicarbonate level was 24 (IQR, 22-26) mEq/L. During a median follow-up of 3.9 years, 374 participants died, 767 had a renal outcome, 332 experienced an atherosclerotic event, and 391 had a congestive heart failure event. In adjusted analyses, the risk of developing a renal end point was 3% lower per 1-mEq/L increase in serum bicarbonate level (HR, 0.97; 95% CI, 0.94-0.99; P = 0.01). The association was stronger for participants with eGFR >45 mL/min/1.73 m(2) (HR, 0.91; 95% CI, 0.85-0.97; P = 0.004). The risk of heart failure increased by 14% (HR, 1.14; 95% CI, 1.03-1.26; P = 0.02) per 1-mEq/L increase in serum bicarbonate level over 24 mEq/L. Serum bicarbonate level was not associated independently with atherosclerotic events (HR, 0.99; 95% CI, 0.95-1.03; P = 0.6) and all-cause mortality (HR, 0.98; 95% CI, 0.95-1.02; P = 0.3). Single measurement of sodium bicarbonate. In a cohort of participants with CKD, low serum bicarbonate level was an independent risk factor for kidney disease progression, particularly for participants with preserved kidney function. The risk of heart failure was higher at the upper extreme of serum bicarbonate levels. There was no association between serum bicarbonate level and all-cause mortality or atherosclerotic events.

Renal failure is one of the most important social problems for its incurability and high costs for patients’ health care. Through clarification of the underlying mechanism for the high susceptibility of cats to renal disease, we here demonstrates that the effective dissociation of serum AIM protein from IgM is necessary for the recovery from acute kidney injury (AKI). In cats, the AIM-IgM binding affinity is 1000-fold higher than that in mice, which is caused by the unique positively-charged amino-acid cluster present in feline AIM. Hence, feline AIM does not dissociate from IgM during AKI, abolishing its translocation into urine. This results in inefficient clearance of lumen-obstructing necrotic cell debris at proximal tubules, thereby impairing AKI recovery. Accordingly, mice whose AIM is replaced by feline AIM exhibit higher mortality by AKI than in wild-type mice. Recombinant AIM administration into the mice improves their renal function and survival. As insufficient recovery from AKI predisposes patients to chronic, end-stage renal disease, feline AIM may be involved crucially in the high mortality of cats due to renal disease. Our findings could be the basis of the development of novel AKI therapies targeting AIM-IgM dissociation, and may support renal function in cats and prolong their lives. PMID:27731392

Pathogenesis of diabetic nephropathy.

Raptis, A E; Viberti, G

2001-01-01

Diabetic Nephropathy (DN) is the commonest cause of end-stage renal failure (ESRF) in the Western world. Diabetic nephropathy follows a well outline clinical course, starting with microalbuminuria through proteinuria, azotaemia and culminating in ESRF. Before the onset of overt proteinuria, there are various renal functional changes including renal hyperfiltration, hyperperfusion, and increasing capillary permeability to macromolecules. Basement-membrane thickening and mesangial expansion have long been recognized as pathological hallmark of diabetes. It has been postulated that DN occurs as a result of the interplay of metabolic and hemodynamic factors in the renal microcirculation. There is no doubt that there is a positive relationship between hyperglycaemia, which is necessary but not sufficient, and microvascular complications. The accumulation of advanced glycosylated end-products (AGEs), the activation of isoform(s) of protein kinase C (PKC) and the acceleration of the aldose reductase pathway may explain how hyperglycemia damages tissue. PKC is one of the key signaling molecules in the induction of the vascular pathology of diabetes. The balance between extracellular matrix production and degradation is important in this context. Transforming growth factor-beta (TGF-beta) appears to play a pivotal role in accumulation in the diabetic kidney. Hemodynamic disturbances are believed to be directly responsible for the development of glomerulosclerosis and its attendant proteinuria. There is familial clustering of diabetic kidney disease. A number of gene loci have been investigated to try to explain the genetic susceptibility to diabetic nephropathy. The genes coding for components of renin-angiotensin system have drawn special attention, due to the central role that this system plays in the regulation of blood pressure, sodium metabolism, and renal hemodynamics. Endothelial dysfunction is closely associated with the development of diabetic retinopathy, nephropathy and atherosclerosis, both in IDDM and in NIDDM. The pathogenesis of diabetic nephropathy is not clarified completely yet.

End-stage renal disease (ESRD) due to lupus nephritis (LN) occurs in 10%-30% of patients. Initially systemic lupus erythematosus (SLE) was a contraindication for kidney transplantation (KT). Today, long-term graft survival remains controversial. Our objective was to compare the survival after KT in patients with SLE or other causes of ESRD. All SLE patients who had undergone KT in a retrospective cohort were included. Renal graft survival was compared with that of 50 controls, matched for age, sex, and year of transplantation. Survival was evaluated by the Kaplan-Meier test and the Cox proportional hazards model. Twenty-five subjects with SLE were included. The estimated 1-year, 2- and 5-year survival rates for patients with SLE were 92%, 66% and 66%. Renal graft survival did not differ between patients with SLE and other causes of ESRD (P=.39). The multivariate analysis showed no significant difference in graft survival between the two groups (hazard ratio, HR=1.95, 95% confidence interval [CI] 0.57-6.61, P=.28). The recurrence rate of LN was 8% and was not associated with graft loss. Acute rejection was the only variable associated with graft loss in patients with SLE (HR=16.5, 95% CI 1.94-140.1, P=.01). Renal graft survival in SLE patients did not differ from that reported for other causes of ESRD.

During the last years, an increasing number of patients with end-stage renal failure caused by various underlying diseases, all over the world, is treated by renal replacement therapy. NUTRITIONAL STATUS: Malnutrition is often found in patients affected by renal failure; it is caused by reduced intake of nutritional substances due to anorexia and dietary restrictions hormonal and metabolic disorders, comorbid conditions and loss of proteins, amino-acids, and vitamins during the dialysis procedure itself. Nutritional status significantly affects the outcome of patients on chronic dialysis treatment. Recent epiodemiological trials have proved that survival on chronic continuous ambulatory peritoneal dialysis program depends more on residual renal function (RRF) than on peritoneal clearances of urea and creatinine. The aim of the study was to analyze the influence of RRF on common biochemical and anthropometric markers of nutrition in 32 patients with end-stage renal failure with various underlying diseases during the first 6 months on continuous ambulatory peritoneal dialysis (CAPD). The mean residual creatinine clearance was 8,3 ml/min and the mean RRF was 16,24 l/week in our patients at the beginning of the chronic peritoneal dialysis treatment. During the follow-up, the RRF slightly decreased, while the nutritional status of patients significantly improved. Gender and age, as well as the leading disease and peritonitis didn't influence the RRF during the first 6 months of CAPD treatment. We found several positive correlations between RRF and laboratory and anthropometric markers of nutrition during the follow-up, proving the positive influence of RRF on nutritional status of patients on chronic peritoneal dialysis.

Dyskeratosis congenita (DC) is a very rare inherited disorder. It is caused by dysfunction of telomere maintenance. It involves RNA telomerase components relevant to various mutations leading to a classic triad of physical findings consisting of nail dystrophy of the hands and feet, mucosal leukoplakia, and reticular pigmentation of the skin, most commonly on the head, neck, and trunk. Bone marrow failure along with pulmonary complications and malignancies are all common causes of premature death in patients with DC as well as other abnormalities. We report a new case of DC with impure nephrotic syndrome relevant to histopathologic signs of a diffuse mesangial sclerosis, leading to an early end-stage renal disease. Challenges remain to understand the diverse spectrum of DC especially in children. To the best of our knowledge this is the first case of DC associated to diffuse mesangial sclerosis.

Hemodialysis knowledge and medical adherence in African Americans diagnosed with end stage renal disease: results of an educational intervention.

Wells, Janie R

2011-01-01

The purpose of this three-group quasi-experimental research study was to describe the relationship between hemodialysis knowledge and perceived medical adherence to a prescribed treatment regimen in African Americans diagnosed with end stage renal disease and to determine if an educational intervention improved hemodialysis knowledge and medical adherence. Eighty-five African Americans participated in this study using the Life Options Hemodialysis Knowledge Test and the Medical Outcomes Study Measures of Patient Adherence tools. No significant correlation was found between hemodialysis knowledge and medical adherence. Paired sample t-tests revealed significantly higher hemodialysis knowledge scores in the post-test group compared to the pre-test group, t(26) = -3.79, p < 0.01. Additionally, no significant differences were found between pre- and post-intervention in medical adherence. This study suggests that more education is needed to improve the knowledge level of African-American patients on hemodialysis.

The end-stage renal disease industry and exit strategies for nephrologists.

PubMed

Sullivan, John D

2006-01-01

The purpose of this presentation is to identify exit strategies for nephrologists under changing conditions in the dialysis market. The end-stage renal disease service provider market continues to be highly receptive to consolidation. Taking advantage of large economies of scale, large for-profit dialysis chains have surpassed independent operators in both number of clinics and total patients. With relatively low barriers to entry, new smaller clinics continue to open, serving a niche outside the larger chains. Additional competition comes in the form of medium players funded by venture capitalists with the added pressure of rapid growth and financial return. To ensure market power in both dialysis products and managed care negotiation leverage, medium and large service providers will continue to seek out attractive acquisition targets. For nephrologists to capitalize on investment, clinic and business preparation will continue to be the driving force for these divestitures.

Adult patients with chronic kidney disease are at risk of major neurologic and cardiac complications. The purpose of this study is to review the neurological and cardiac complications in children with end-stage renal disease (ESRD). A retrospective review of medical records of children with ESRD at Jordan University Hospital was performed. All neurological and cardiac events were recorded and analyzed. Data of a total of 68 children with ESRD presenting between 2002 and 2013 were reviewed. Neurological complications occurred in 32.4%; seizures were the most common event. Uncontrolled hypertension was the leading cause of neurological events. Cardiac complications occurred in 39.7%, the most common being pericardial effusion. Mortality from neurological complications was 45%. Neurological and cardiac complications occurred in around a third of children with ESRD with a high mortality rate. More effective control of hypertension, anemia, and intensive and gentle dialysis are needed.

p-Cresyl glucuronide (p-CG) is a by-product of tyrosine metabolism that accumulates in patients with end-stage renal disease. p-CG binding to human serum albumin in physiological conditions (37°C, pH 7.40) was studied by ultrafiltration (MWCO 10 kDa) and data were analyzed assuming one binding site. The estimated value of the association constant was 2.77×10 3  M -1 and a maximal stoichiometry of 3.80 mol per mole. At a concentration relevant for end-stage renal patients, p-CG was 23% bound to albumin. Competition experiments, using fluorescent probes, demonstrated that p-CG did not bind to Sudlow's site I or site II. The p-CG did not interfere with the binding of p-cresyl-sulfate or indoxyl sulfate to serum albumin. Copyright © 2018. Published by Elsevier B.V.

Renal involvement in anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis contributes to significant morbidity and mortality in patients. In chronic inflammation, B cells are recruited to the inflamed tissue and organised lymphoid structures have been described in several autoimmune diseases. The aim of this study was to correlate the lymphoid organisation in renal biopsies with renal outcome in ANCA-associated glomerulonephritis (GN). We investigated 112 renal biopsies from patients with newly diagnosed ANCA-associated necrotising GN. We identified four different levels of the intrarenal organisation of lymphocytes: T cells without B cells, scattered B and T cells, clustered lymphocytic infiltrates and nodular compartmentally arranged B and T cell aggregates. Almost half the patients showed clusters of B and T lymphocytes in their biopsies. In 15 of these biopsies, a higher degree of organisation with lymphocytic compartments was detected. Inflammatory cell organisation was associated with renal failure, but not with tubular atrophy and interstitial fibrosis. Patients with organised lymphocytic infiltrates in their biopsy had worse renal function during follow-up and were more likely to develop end stage renal disease. In the present study, we show that the renal lymphocytic organisation is associated with renal outcome in ANCA-associated GN. The organisation of the lymphocytic infiltrate may be a morphological correlate of a perpetual and exaggerated inflammation in renal ANCA disease. Classifying the lymphocytic infiltrate could help to predict renal outcome, and might therefore be used for individualised adjustments in the intensity and duration of immunosuppressive therapy. © 2018 John Wiley & Sons Ltd.

Analogy of cardiac and renal complications in essential hypertension and aged SHR or L-NAME/SHR.

PubMed

Zhou, Xiaoyan; Frohlich, Edward D

2007-01-01

Hypertension plays major causative roles in development of cardiac failure and end-stage renal disease (ESRD). Cardiac and renal involvements in hypertension and relevant pharmacological interventions have been extensively studied in our laboratories. Our findings demonstrated that aged spontaneous hypertensive rats (SHR) developed reduced coronary flow reserve, increased coronary vascular resistance and cardiac fibrosis, and impaired cardiac function. Moreover, aged SHR naturally developed glomerular hypertension and ischemia, proteinuria, and glomerular sclerosis and interstitial fibrosis. These naturally-occurring cardiac and renal involvements in aged SHR are very similar to these target organ changes in essential hypertension. Furthermore, we have been able to reproduce similar derangements in younger adult SHR by nitric oxide synthesis inhibition. These changes are identical to the pathophysiological alterations in heart and kidney found in old SHR as well as clinically. Antihypertensive therapeutic interventions provided cardiac and renal protection and, perhaps even prevention in the aged SHR and younger adult SHR with suppressed nitric oxide synthesis. Recent clinical trails have translated these pathophysiological observations demonstrating that angiotensin II inhibition affords remarkable cardiac and renal benefits to patients with essential hypertension. Thus, both the aged SHR as well as younger adult SHR with suppressed nitric oxide synthesis very closely mimic the cardiac and renal outcomes seen in patients with essential hypertension. They accordingly have become extremely useful experimental models of hypertensive heart disease and ESRD seen with severe nephrosclerosis. The latter hypertensive rat model with induced endothelial dysfunction is recommended enthusiastically for its foregoing as well as time-saving and economic values.

End-stage renal disease and dialysis is commonly associated with poor outcomes after joint replacement surgery. The goal of this study was to evaluate postoperative complications in patients with less advanced chronic kidney disease undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA). Patients who underwent THA or TKA between 2004 and 2011 with stage 1, 2, or 3 chronic kidney disease were retrospectively reviewed via an electronic medical record. The authors compared 377 patients who had stage 1 to 2 chronic kidney disease with 402 patients who had stage 3 chronic kidney disease. No significant differences in 90-day readmission or revision rates were found between the stage 1 to 2 and stage 3 patient groups. For patients with stage 3 chronic kidney disease, the overall mortality rate was greater than that in patients with stage 1 to 2 chronic kidney disease. However, when adjusted for comorbid disease, no significant increases were seen in joint infection, readmission, or early revision between patients with stage 1 to 2 chronic kidney disease vs patients with stage 3 chronic kidney disease. The overall incidence of infection was high (3.5%) but far less than reported for patients with end-stage renal disease, dialysis, and kidney transplant. In conclusion, patients with stage 1, 2, or 3 chronic kidney disease may have a higher than expected rate of prosthetic joint infection (3.5%) after total joint arthroplasty. Patients with stage 3 chronic kidney disease are at higher risk for postoperative mortality compared with those with lesser stages of kidney disease. Copyright 2014, SLACK Incorporated.

The burden of hyperkalemia in patients with cardiovascular and renal disease.

PubMed

Dunn, Jeffrey D; Benton, Wade W; Orozco-Torrentera, Ernesto; Adamson, Robert T

2015-11-01

Hyperkalemia is a potentially serious condition that can result in life-threatening cardiac arrhythmias and is associated with an increased mortality risk. Patients older than 65 years who have an advanced stage of chronic kidney disease (stage 3 or higher), diabetes, and/or chronic heart failure are at higher risk for hyperkalemia. To reduce disease progression and improve outcomes in these groups of patients, modulation of the renin-angiotensin-aldosterone system (RAAS) is recommended by guidelines. One limiting factor of RAAS inhibitors at proven doses is the increased risk for hyperkalemia associated with their use. Although there are effective therapeutic options for the short-term, acute management of hyperkalemia, the available strategies for chronic control of high potassium levels have limited effectiveness. The management of high potassium in the long term often requires withdrawing or reducing the doses of drugs proven to reduce cardiovascular and renal outcomes (eg, RAAS inhibitors) or implementing excessive and often intolerable dietary restrictions. Furthermore, withholding RAAS inhibitors may lead to incremental healthcare costs associated with poor outcomes, such as end-stage renal disease, hospitalizations due to cardiovascular causes, and cardiovascular mortality. As such, there is an important unmet need for novel therapeutic options for the chronic management of patients at risk for hyperkalemia. Potential therapies in development may change the treatment landscape in the near future.

This study describes the time trend of renal replacement therapy for end-stage renal disease (ESRD) in the Provence-Alpes Côte d'Azur region (PACA) between 2004 and 2015, and forecasts up to 2030. A longitudinal study was conducted on all ESRD patients treated in PACA and recorded in the French Renal Epidemiology and Information Network (REIN) during this period. Time trends and forecasts to 2030 were analyzed using Poisson regression models. Since 2004, the number of new patients has steadily increased by 3.4% per year (95% CI, 2.8-3.9, p < 0.001) and the number of patients receiving RRT has increased by 3.7% per year (RR 1.037, 95% CI: 1.034-1.039, p < 0.001). If these trends continue, the PACA region will be face with 7371 patients on dialysis and 3891 with a functional renal transplant who will need to be managed in 2030. The two most significant growth rates were the percentage of obese people (RR 1.140, 95% CI: 1.131-1.149, p < 0.001) and those with diabetes (RR 1.070, 95% CI; 1.064-1.075, p < 0.001). This study highlights the increase in the number of ESRD patients over 12 years, with no prospect of stabilization. These findings allow us to anticipate the quality and quantity of care offered and to propose more preventive measures to combat obesity and diabetes.

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

We sought to ascertain the long-term outcome and genotype-phenotype correlations available for primary hyperoxaluria type 1 in a large retrospective cohort study. We examined the clinical history of 155 patients (129 families primarily from Western Europe, North Africa, or the Middle East) as well as the enzymatic or genetic diagnosis. The median age at first symptom was 4 years, and at diagnosis 7.7 years, at which time 43% had reached end-stage renal disease. Presentations included: (1) early nephrocalcinosis and infantile renal failure, (2) recurrent urolithiasis and progressive renal failure diagnosed during childhood, (3) late onset with occasional stone passage diagnosed in adulthood, (4) diagnosis occurring on post-transplantation recurrence, and (5) family screening. The cumulative patient survival was 95, 86, and 74% at ages 10, 30, and 50 years, respectively, with the cumulative renal survival of 81, 59, 41, and 10% at ages 10, 20, 30, and 50 years, respectively; 72 patients had undergone a total of 97 transplantations. Among the 136 patients with DNA analysis, the most common mutation was p.Gly170Arg (allelic frequency 21.5%), with a median age at end-stage renal disease of 47 years for homozygotes, 35 years for heterozygotes, and 21 years for other mutations. Our results underscore the severe prognosis of primary hyperoxaluria type 1 and the necessity for early diagnosis and treatment, as well as confirm a better prognosis of the p.Gly170Arg mutation.

Major Depressive Disorder (MDD) is highly prevalent in patients with End Stage Renal Disease (ESRD) treated with maintenance hemodialysis (HD). Despite the high prevalence and robust data demonstrating an independent association between depression and poor clinical and patient-reported outcomes, MDD is under-treated when identified in such patients. This may in part be due to the paucity of evidence confirming the safety and efficacy of treatments for depression in this population. It is also unclear whether HD patients are interested in receiving treatment for depression. ASCEND (Clinical Trials Identifier Number NCT02358343), A Trial of Sertraline vs. Cognitive Behavioral Therapy (CBT) for End-stage Renal Disease Patients with Depression, was designed as a multi-center, 12-week, open-label, randomized, controlled trial of prevalent HD patients with comorbid MDD or dysthymia. It will compare (1) a single Engagement Interview vs. a control visit for the probability of initiating treatment for comorbid depression in up to 400 patients; and (2) individual chair-side CBT vs. flexible-dose treatment with a selective serotonin reuptake inhibitor, sertraline, for improvement of depressive symptoms in 180 of the up to 400 patients. The evolution of depressive symptoms will also be examined in a prospective longitudinal cohort of 90 HD patients who choose not to be treated for depression. We discuss the rationale and design of ASCEND, the first large-scale randomized controlled trial evaluating efficacy of non-pharmacologic vs. pharmacologic treatment of depression in HD patients for patient-centered outcomes.

OBJECTIVES: To evaluate whether ceramic workers exposed to silica experience an excess of end stage renal disease. METHODS: On the basis of a health surveillance programme, a cohort of 2980 male ceramic workers has been enrolled during the period 1974-91 in Civitacastellana, Lazio, Italy. For each worker, employment history, smoking data, and x ray film readings were available. The vital status was ascertained for all cohort members. All 2820 people still alive and resident in the Lazio region as in June 1994 were searched for a match in the regional end stage renal diseases registry, which records (since June, 1994) all patients undergoing dialysis treatment in public and private facilities of the region. Expected numbers of prevalent cases from the cohort were computed by applying the rate of patients on dialysis treatment by the age distribution of the cohort. RESULTS: A total of six cases was detected when 1.87 were expected (observed/expected (O/E) = 3.21; 95% confidence interval (95% CI) 1.17 to 6.98). The excess risk was present among non-smokers (O = 2; O/E = 4.34) and smokers (O = 4; O/E = 2.83), as well as among workers without silicosis (O = 4; O/E = 2.78) and workers with silicosis (O = 2; O/E = 4.54). The risk was higher among subjects with < 20 years since first employment (O = 4; O/E = 4.65) than among those employed > 20 years. CONCLUSION: These results provide further evidence that exposure to silica dust among ceramic workers is associated with nephrotoxic effects.   PMID:10492655

Hyperphosphataemia is a major problem in patients with chronic kidney disease as it has been associated with increased morbidity and mortality. Over the last four decades, different modalities have been applied to treat hyperphosphataemia with varying degrees of success. Unfortunately, treatment strategies have led to unforeseen complications. These have prompted the development of new classes of medications with potentially better efficacy and few short-term and long-term side effects. This article reviews the causes, mechanism and management of hyperphosphataemia.

In the early 1960s, peritoneal dialysis (PD) was introduced as a form of long-term maintenance therapy in patients with end-stage renal disease (ESRD). We have come a long way since. Increasing understanding of peritoneal kinetic behavior, its innovative manipulation to meet patient needs, critical monitoring of clinical outcomes, and parallel development in technology have all contributed to the worldwide success of the therapy over the past four decades. In this article we review the evolution of the various PD modalities in the context of these factors.

This study aims to determine whether uric acid levels contribute to new renal damage in systemic lupus erythematosus (SLE) patients. This prospective study was conducted in consecutive patients seen since 2012. Patients had a baseline visit and follow-up visits every 6 months. Patients with ≥2 visits were included; those with end-stage renal disease (regardless of dialysis or transplantation) were excluded. Renal damage was ascertained using the SLICC/ACR damage index (SDI). Univariable and multivariable Cox-regression models were performed to determine the risk of new renal damage. Uric acid was included as a continuous and dichotomous (per receiving operating characteristic curve) variable. Multivariable models were adjusted for age at diagnosis, disease duration, socioeconomic status, SLEDAI, SDI, serum creatinine, baseline use of prednisone, antimalarials, and immunosuppressive drugs. One hundred and eighty-six patients were evaluated; their mean (SD) age at diagnosis was 36.8 (13.7) years; nearly all patients were mestizo. Disease duration was 7.7 (6.8) years. Follow-up time was 2.3 (1.1) years. The SLEDAI was 5.2 (4.3) and the SDI 0.8 (1.1). Uric acid levels were 4.5 (1.3) mg/dl. During follow-up, 16 (8.6%) patients developed at least one new point in the renal domain of the SDI. In multivariable analyses, uric acid levels (continuous and dichotomous) at baseline predicted the development of new renal damage (HR 3.21 (1.39-7.42), p 0.006; HR 18.28 (2.80-119.48), p 0.002; respectively). Higher uric acid levels contribute to the development of new renal damage in SLE patients independent of other well-known risk factors for such occurrence.

This study is a retrospective, nationwide, matched cohort study to investigate the risk of band keratopathy following end-stage renal disease (ESRD). The study cohort included 94,039 ESRD on-dialysis patients identified by the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), code 585 and registered between January 2000 to December 2009 at the Taiwan National Health Insurance Research Database. An age- and sex-matched control group comprised 94,039 patients selected from the Taiwan Longitudinal Health Insurance Database 2000. Information for each patient was collected from the index date until December 2011. In total, 230 ESRD patients and 26 controls had band keratopathy (P < 0.0001) during the follow-up period, indicating a significantly elevated risk of band keratopathy in the ESRD patients compared with controls (incidence rate ratio = 12.21, 95% confidence interval [CI] = 8.14-18.32). After adjustment for potential confounders including sarcoidosis, hyperparathyroidism, iridocyclitis, and phthisis bulbi, ESRD patients were 11.56 times more likely to develop band keratopathy in the full cohort (adjusted HR = 11.56, 95% CI = 7.70-17.35). In conclusion, ESRD increases the risk of band keratopathy. Close interdisciplinary collaboration between nephrologists and ophthalmologists is important to deal with band keratopathy following ESRD and prevent visual acuity impairments.

Background and objectives We investigated the association of urinary potassium and sodium excretion with the incidence of renal failure and cardiovascular disease in patients with type 2 diabetes. Design, setting, participants, & measurements A total of 623 Japanese type 2 diabetic patients with eGFR≥60 ml/min per 1.73 m2 were enrolled in this observational follow-up study between 1996 and 2003 and followed-up until 2013. At baseline, a 24-hour urine sample was collected to estimate urinary potassium and sodium excretion. The primary end point was renal and cardiovascular events (RRT, myocardial infarction, angina pectoris, stroke, and peripheral vascular disease). The secondary renal end points were the incidence of a 50% decline in eGFR, progression to CKD stage 4 (eGFR<30 ml/min per 1.73 m2), and the annual decline rate in eGFR. Results During the 11-year median follow-up period, 134 primary end points occurred. Higher urinary potassium excretion was associated with lower risk of the primary end point, whereas urinary sodium excretion was not. The adjusted hazard ratios for the primary end point in Cox proportional hazards analysis were 0.56 (95% confidence interval [95% CI], 0.33 to 0.95) in the third quartile of urinary potassium excretion (2.33–2.90 g/d) and 0.33 (95% CI, 0.18 to 0.62) in the fourth quartile (>2.90 g/d) compared with the lowest quartile (<1.72 g/d). Similar associations were observed for the secondary renal end points. The annual decline rate in eGFR in the fourth quartile of urinary potassium excretion (–1.3 ml/min per 1.73 m2/y; 95% CI, –1.5 to –1.0) was significantly slower than those in the first quartile (–2.2; 95% CI, –2.4 to –1.8). Conclusions Higher urinary potassium excretion was associated with the slower decline of renal function and the lower incidence of cardiovascular complications in type 2 diabetic patients with normal renal function. Interventional trials are necessary to determine whether increasing dietary potassium is beneficial. PMID:26563378

The prevalence of chronic kidney disease (CKD) in Asia is expected to increase along with increases of hypertension and diabetes. Most cases are not treated and progress to end-stage renal disease (ESRD) with an increased risk for cardiovascular complications. Renal replacement therapies are so expensive that most ESRD patients die without treatment. Thus, countermeasures against early stages of CKD are urgently needed. Nevertheless, basic information for CKD has not been reported in Vietnam. We conducted a survey of CKD in 8,505 inhabitants aged >40 years in Vietnam. Subjects with abnormal urinary findings were further examined, including serum creatinine levels. In this study, CKD was defined as <60 ml/min/1.73 m(2) of estimated creatinine clearance by the Cockcroft-Gault method. We identified 3.1% of subjects as CKD (stages 3-5) with positive findings in urine test. We also found that elderly hypertension and malnutrition were independent risk factors for CKD in this population. We found a significant number of CKD patients in Vietnam. To avoid a CKD pandemic in Asia including Vietnam, we strongly suggest further analyses of risk factors and prognosis of CKD in these populations, and the development of efficient management systems suitable for Asia.

The goals are simple: Improve well-being of the dialysis patient and reduce hospitalizations. The tools are diverse: Ultrapure dialysate. On-line blood monitoring. Biocompatible membranes. No reuse. Daily, in-center dialysis and possibly nocturnal dialysis at home. Reimbursement: Full-risk capitation, With Medicare and commercial payor rates varying on a patient-by-patient basis. Create an incubator with approximately 1,000 end-stage renal disease patients, treated at both capitated payment-exclusive dialysis units and mingled in at traditional fee-for-service clinics. Establish a team of nurses and renal care staff to direct the care plan, and put the program in place. After the first year, analyze the data and see if the end--hopefully, improved outcomes and resulting reduced hospitalizations--justifies the means--the higher cost for "optimal technologies."

The renal cell cancer incidence is relatively low in younger patients, encompassing 3% to 7% of all renal cell cancers. While young patients may have renal tumors due to hereditary syndromes, in some of them sporadic renal cancers develop without any family history or known genetic mutations. Our recent observations from clinical practice have led us to hypothesize that there is a difference in histological distribution in younger patients compared to the older cohort. We queried the SEER (Surveillance, Epidemiology and End Results) 18-registry database for all patients 20 years old or older who were surgically treated for renal cell carcinoma between 2001 and 2008. Patients with unknown race, grade, stage or histology and those with multiple tumors were excluded from study. Four cohorts were created by dividing patients by gender, including 1,202 females and 1,715 males younger than 40 years old, and 18,353 females and 30,891 males 40 years old or older. Chi-square analysis was used to compare histological distributions between the cohorts. While clear cell carcinoma was still the most common renal cell cancer subtype across all genders and ages, chromophobe renal cell cancer was the most predominant type of nonclear renal cell cancer histology in young females, representing 62.3% of all nonclear cell renal cell cancers (p <0.0001). In all other groups papillary renal cell cancer remained the most common type of nonclear renal cell cancer. It is possible that hormonal factors or specific pathway dysregulations predispose chromophobe renal cell cancer to develop in younger women. We hope that this work provides some new observations that could lead to further studies of gender and histology specific renal tumorigenesis.

Our objective was to evaluate the incidence of renal replacement therapy after orthotopic liver transplant and to evaluate and analyze patient outcomes. We performed a retrospective analysis of 177 consecutive patients at a tertiary care unit who underwent orthotopic liver transplant between January 2010 and June 2016. Patients who were admitted to the intensive care unit after orthotopic liver transplant and who required renal replacement therapy were included. A total of 177 (79 adult, 98 pediatric) orthotopic liver transplants were performed during the study period. Of these, 35 patients (19%) required renal replacement therapy during the early posttransplantation period. After excluding 5 patients with previous chronic renal failure, 30 patients (17%; 20 adult [25% ], 10 pediatric [10% ]) with acute kidney injury required renal replacement therapy. The mean patient age was 31.1 ± 20.0 years, with a mean Model for End-stage Liver Disease score of 16.7 ± 12.3. Of the patients with acute kidney injury who underwent renal replacement therapy, in-hospital mortality was 23.3% (7 of 30 patients), and 40% remained on dialysis. No significant difference was seen in mortality between early versus delayed initiation of renal replacement therapy in patients with stage 3 acute kidney injury (P = .17). Of liver transplant recipients who present with acute kidney injury, 19% require renal replacement therapy, and in-hospital mortality is 20% in the early postoperative period.

To study the effect of triple organ transplantation (liver, kidney, and pancreas) in patient of end-stage liver disease with renal failure and diabetes, and to explore the optimal surgical procedure. Simultaneous piggyback orthotopic heterotopic liver, pancreas-duodenum, and kidney transplantation was performed on a 43-year-old male patient with exocrine pancreatic insufficiency and insulin-dependent diabetes related to chronic pancreatitis (CP) who developed hepatic and renal failure. The pancreatic exocrine secretions were drained enterically to the jejunum. Prednisone, tacrolimus, mycophenolate mofetil, and ATG were used as immunosuppression therapy. Good liver and pancreas allograft function recovery was achieved within 7 days after the operation. And the recovery of renal allograft function was delayed. The renal allograft was removed because of break-down of renal blood flow 16 days after the transplantation. A new renal transplantation was performed at the same position. The second kidney graft recovered its normal function 3 days later. Up to the writing of this paper no acute rejection of organs and such complications as pancreatitis, thrombosis, and localized infection occurred. The patient became insulin independent with normal liver and renal function. Simultaneous piggyback orthotopic heterotopic liver, pancreas-duodenum, and kidney transplantation can be a good method for the patients with exocrine pancreatic insufficiency and insulin-dependent diabetes combined with hepatic and renal failure.

[Perioperative acute kidney injury and failure].

PubMed

Chhor, Vibol; Journois, Didier

2014-04-01

Perioperative period is very likely to lead to acute renal failure because of anesthesia (general or perimedullary) and/or surgery which can cause acute kidney injury. Characterization of acute renal failure is based on serum creatinine level which is imprecise during and following surgery. Studies are based on various definitions of acute renal failure with different thresholds which skewed their comparisons. The RIFLE classification (risk, injury, failure, loss, end stage kidney disease) allows clinicians to distinguish in a similar manner between different stages of acute kidney injury rather than using a unique definition of acute renal failure. Acute renal failure during the perioperative period can mainly be explained by iatrogenic, hemodynamic or surgical causes and can result in an increased morbi-mortality. Prevention of this complication requires hemodynamic optimization (venous return, cardiac output, vascular resistance), discontinuation of nephrotoxic drugs but also knowledge of the different steps of the surgery to avoid further degradation of renal perfusion. Diuretics do not prevent acute renal failure and may even push it forward especially during the perioperative period when venous retourn is already reduced. Edema or weight gain following surgery are not correlated with the vascular compartment volume, much less with renal perfusion. Treatment of perioperative acute renal failure is similar to other acute renal failure. Renal replacement therapy must be mastered to prevent any additional risk of hemodynamic instability or hydro-electrolytic imbalance. Copyright © 2014 Association Société de néphrologie.

Prescription opioid abuse poses a serious problem in the United States, representing 615 per 100,000 deaths annually. Extended-release oxymorphone (Opana-ER) is an oral opioid pain medication that has recently been found to cause thrombotic microangiopathy when intravenously abused. In this retrospective study, prevalence and outcomes of AKI among patients intravenously abusing extended-release oral oxymorphone were analyzed. A query of electronic medical records for "drug abuse" at an academic medical center during January 2012 to December 2015 was performed and yielded 2350 patients. Patients were further identified by documented intravenous abuse of extended-release oxymorphone. Patients were stratified based on multiple renal indices and outcomes. Potential confounders were also identified. 165 patients were found to have a documented history of intravenous abuse of extended-release oral oxymorphone. Prevalence of AKI in this population was a 47.8%. KDIGO stage-I patients consisted of 17.8% of patients with AKI, 40.5% were classified as KDIGO stage-II AKI, and 41.8% were classified as KDIGO stage-III AKI. Among patients with AKI, average age was found to be 37.5 years, 59.4% experienced renal recovery, 56.9% required intensive care unit admission, 13.9% progressed to end-stage renal disease (ESRD), and 7.6% expired during admission. Clinicians should be educated to help recognize intravenous abuse of extended-release oral oxymorphone and its associated effects. Our data suggests AKI is common in these patients; higher KDIGO staging appears to be associated with slower rates of renal recovery, increased comorbidities and progression to both CKD and ESRD.

Autosomal dominant polycystic kidney disease (ADPKD) is characterized by slowly progressive bilateral renal cyst growth ultimately resulting in loss of kidney function and end-stage renal disease (ESRD). Disease progression rate and age at ESRD are highly variable. Therapeutic interventions therefore require early risk stratification of patients and monitoring of disease progression in response to treatment. We used a urine peptidomic approach based on capillary electrophoresis-mass-spectrometry (CE-MS) to identify potential biomarkers reflecting the risk for early progression to ESRD in the Consortium of Radiologic Imaging in Polycystic Kidney Disease (CRISP) cohort. A biomarker-based classifier consisting of 20 urinary peptides allowed the prediction of ESRD within 10-13 years of follow-up in patients 24-46 years of age at baseline. The performance of the biomarker score approached that of height-adjusted total kidney volume (htTKV) and the combination of the biomarker panel with htTKV improved prediction over either one alone. In young patients (<24 years at baseline), the same biomarker model predicted a 30 mL/min/1.73 m 2 glomerular filtration rate decline over 8 years. Sequence analysis of the altered urinary peptides and the prediction of the involved proteases by in silico analysis revealed alterations in distinct proteolytic pathways, in particular matrix metalloproteinases and cathepsins. We developed a urinary test that accurately predicts relevant clinical outcomes in ADPKD patients and suggests altered proteolytic pathways involved in disease progression. © The Author 2016.

Angiontension-converting enzyme inhibitors (ACEIs) are beneficial in the treatment of diabetic and nondiabetic kidney disease, coronary artery disease and congestive heart failure. One adverse effect of ACEIs use is a rise in serum creatinine and potential renal failure. This paper attempts to quantify this risk and assess the need for pre- and post-ACEI serum creatinine measurements. A computerized search of Kaiser Permanente Northwest's electronic medical record was conducted to find patients over the age of 40 years taking lisinopril between July 1, 2000 and June 30, 2002. Patient demographic information and presence in diabetes and coronary artery disease registries was collected. A subsequent search for pre- and postlisinopril serum creatinine levels within 6 months of initial lisinopril prescription was conducted. Patients with prelisinopril creatinine < or = 1.2 mg/dl and postlisinopril creatinine > 2.5 mg/dl underwent chart review to discern adverse events associated with the rise in serum creatinine. A total of 18,977 patients were prescribed lisinopril between July 1, 2000 and June 30, 2002. In all 13 166 patients had a pre- and postlisinopril creatinine checked. In all, 31 patients had a rise in creatinine from < or = 1.2 mg/dl to > 2.5 mg/dl (0.2%). Possible contributors to rise in creatinine included congestive heart failure, dehydration and infection. No patients developed end-stage renal disease, although three died. In conclusion, end-stage renal disease is an unlikely outcome among patients prescribed lisinopril and is most likely associated with other events.

The prevalence of uremic pericarditis (UP) used to range from 3% to 41%. More recently, it has decreased to about 5%-20% and to <5% in the last decades, as hemodialysis techniques have become widely used and dialysis quality improved. The objective of this work is to determine the initial clinical picture and the prognosis of patients presenting End Stage Renal Disease (ESRD) with UP. This is a retrospective study (May 2015-September 2017). Inclusion criteria targeted patients who had uremic pericarditis defined as pericarditis occurring in a patient with ESRD before initiation of renal replacement therapy, or within eight weeks of its initiation. 16 patients met the inclusion criteria. The median age of patients was 54 [24, 71] years and 56.2% were male. Pericardial effusion was small, moderate and large in 31.2%, 37.6% and 31.2% of cases respectively. One pericardiocentesis was performed in view of a clinical picture of impending cardiac tamponade and three pericardial drainages were performed given presentation of tamponade. Hemodialysis was initiated for all the patients and continued for 2 to 3weeks until complete regression of the pericardial effusion. The mean number of dialysis sessions was 11±3.5. One patient died of septic shock that developed three weeks after diagnosis of uremic pericarditis. UP is considered a rare but fatal complication of ESRD because of the risk of tamponade and its prognosis remains dependent on early diagnosis and adequate treatment of ESRD.

Supra-vesical urinary diversion and ureteric re-implantation for malignant disease.

PubMed

Woodhouse, C R J

2010-11-01

Supra-vesical diversion or ureteric reconstruction is indicated for fistulae from the bladder or ureter, urinary incontinence, painful frequency and for end-stage renal failure due to obstructive uropathy. In a palliative setting, conservative measures, such as an indwelling catheter or ureteric stents, should be tried first. Open or laparoscopic surgery should be considered if these measures fail. For a patient who is leaking urine or has a very painful bladder, such surgery may well be justified, even very close to the end of life, as the symptoms are so unpleasant. When the problem is of end-stage renal failure that may be symptomless, the decision is more difficult; the patient may only gain a few months of life with no change in symptoms in return for the major surgery. The options available include cutaneous diversion either by ureterostomy or conduit and reconstruction either by re-implanting a ureter into the bladder or transuretero-ureterostomy. A laparoscopic approach may be possible in many cases. Copyright © 2010 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.

The objective of this study is to analyze long-term outcomes and kidney function in children requiring continuous renal replacement therapy (CRRT) after an acute kidney injury episode. A retrospective observational study was performed using a prospective database of 128 patients who required CRRT admitted to the pediatric intensive care unit between years 2006 and 2012. The subsequent outcomes were assessed in those surviving at hospital discharge. Of the 128 children who required RRT in the pediatric intensive care unit, 71 survived at hospital discharge (54.4%), of whom 66 (92.9%) were followed up. Three patients had chronic renal failure prior to admission to the NICU. Of the 63 remaining patients, 6 had prolonged or relapses of renal function disturbances, but only one patient with atypical Hemolytic Uremic Syndrome developed end-stage renal failure. The rest had normal kidney function at the last check-up. Most of surviving children that required CRRT have a positive outcome later on, presenting low mortality rates and recovery of kidney function in the medium term.

End-stage renal disease (ESRD) is an important public health problem, especially in developing countries due to the high level of economic resources needed to maintain patients in the different programs that make up renal replacement therapy (RRT). To analyze the differences and inequalities involved in access to RRT in the BRICS countries (Brazil, Russian Federation, India, China and South Africa). This is an applied, descriptive, cross-sectional, quantitative and qualitative study, with documentary analysis and a literature review. The sources of data were from national censuses and scientific publications regarding access to RRT in the BRICS countries. There is unequal access to RRT in all the BRICS countries, as well as the absence of information regarding dialysis and transplants (India), the absence of effective legislation to inhibit the trafficking of organs (India and South Africa) and the use of deceased prisoners as donors for renal transplants (China). The construction of mechanisms to promote the sharing of benefits and solidarity in the field of international cooperation in the area of renal health involves the recognition of bioethical issues related to access to RRT in the BRICS countries.

2013-01-01

Diabetic nephropathy (DN) is a leading cause of end-stage renal disease (ESRD). The inhibitors of renin-angiotensin-aldosterone system (RAAS) can alleviate some of the symptoms of DN but fail to stop the progression to ESRD. Our previous studies demonstrate renoprotective action of nitro-oleic acid (OA-NO2) in several rodent models of renal disease. Here we examined the therapeutic potential and the underlying mechanism of combination of losartan and OA-NO2 in db/db mice. OA-NO2 was infused at 5 mg·kg−1·day−1 via osmotic minipump, and losartan was incorporated into diet at 10 mg·kg−1·day−1, each administered alone or in combination for 2 wk. Diabetic db/db mice developed progressive albuminuria and glomerulosclerosis, accompanied by podocytes loss, increased indexes of renal fibrosis, oxidative stress, and inflammation. Treatment of the diabetic mice with OA-NO2 or losartan alone moderately ameliorated kidney injury; however, the combined treatment remarkably reduced albuminuria, restored glomerular filtration barrier structure, and attenuated glomerulosclerosis, accompanied with significant suppression of renal oxidative stress and inflammation. These data demonstrate that combination of losartan and OA-NO2 effectively reverses renal injury in DN. PMID:23946292

End-stage renal disease is a disease with a long duration, requiring patients to live with the limitations imposed by their condition. Stressors associated with this disease are demanding, with patients dependent on support from their social environment. Here, we aimed to show the influences of familial, social, economic, and marital status on quality of life in patients with end-stage renal disease. Patients (190 women/188 men) who were under hemodialysis treatment and on transplant wait lists were included in the study. To evaluate the quality of life, patients completed the Short Form 36 health survey questionnaire voluntarily while undergoing hemodialysis treatment. All Short Form 36 questionnaire components were analyzed separately, and all social, economic, and business life dimensions were examined with another questionnaire. Significant differences were observed between single and married patients regarding physical and mental health dimensions (P < .001), with quality of life higher in single patients than in married. Patients who lived in villages had lower health quality than patients who resided in cities or towns (P < .01). Patients who were home owners and who had a job had higher degrees of health quality than those who did not (P < .01). The lowest Short Form 36 scores were in housewives and farmers (P < .001). Comparisons between patients who went home after hemodialysis versus those who went to work showed better Short Form 36 scores in working patients (P < .001). Patients with private insurance and family support had better Short Form 36 scores (P < .001). Patients who did not comply with their doctor and dietician showed the lowest health quality (P < .05). Regular or irregular drug use did not affect scores. Familial, social, economic, and marital statuses, in addition to the influence of disease adaptation, independently affected the well-being of patients with end-stage renal disease.

Comparative effectiveness studies to improve clinical outcomes in end stage renal disease: the DEcIDE patient outcomes in end stage renal disease study

Background Evidence is lacking to inform providers’ and patients’ decisions about many common treatment strategies for patients with end stage renal disease (ESRD). Methods/design The DEcIDE Patient Outcomes in ESRD Study is funded by the United States (US) Agency for Health Care Research and Quality to study the comparative effectiveness of: 1) antihypertensive therapies, 2) early versus later initiation of dialysis, and 3) intravenous iron therapies on clinical outcomes in patients with ESRD. Ongoing studies utilize four existing, nationally representative cohorts of patients with ESRD, including (1) the Choices for Healthy Outcomes in Caring for ESRD study (1041 incident dialysis patients recruited from October 1995 to June 1999 with complete outcome ascertainment through 2009), (2) the Dialysis Clinic Inc (45,124 incident dialysis patients initiating and receiving their care from 2003–2010 with complete outcome ascertainment through 2010), (3) the United States Renal Data System (333,308 incident dialysis patients from 2006–2009 with complete outcome ascertainment through 2010), and (4) the Cleveland Clinic Foundation Chronic Kidney Disease Registry (53,399 patients with chronic kidney disease with outcome ascertainment from 2005 through 2009). We ascertain patient reported outcomes (i.e., health-related quality of life), morbidity, and mortality using clinical and administrative data, and data obtained from national death indices. We use advanced statistical methods (e.g., propensity scoring and marginal structural modeling) to account for potential biases of our study designs. All data are de-identified for analyses. The conduct of studies and dissemination of findings are guided by input from Stakeholders in the ESRD community. Discussion The DEcIDE Patient Outcomes in ESRD Study will provide needed evidence regarding the effectiveness of common treatments employed for dialysis patients. Carefully planned dissemination strategies to the ESRD community will enhance studies’ impact on clinical care and patients’ outcomes. PMID:23217181

Patients on peritoneal dialysis experience inflammation associated with advanced chronic kidney disease and the therapy itself. An important consequence of the inflammation may be acceleration of the rate of decline in residual renal function. The decline in residual renal function has been associated with an increased mortality for patients in this population. Bardoxolone methyl is a synthetic triterpenoid. To date, the effects of bardoxolone methyl on kidney function in humans have been studied in patients with type 2 diabetes mellitus. A large-scale event-driven study of bardoxolone methyl in patients with type 2 diabetes mellitus with stage 4 chronic kidney disease is underway. The safety of bardoxolone methyl has not been evaluated in patients with more advanced (stage 5) chronic kidney disease or patients on dialysis. This report describes a proposed double blind, prospective evaluation of bardoxolone methyl in patients with type 2 diabetes mellitus receiving peritoneal dialysis. In addition to assessing the safety of bardoxolone methyl in this population, the study will evaluate the effect of bardoxolone methyl on residual renal function over 6 months as compared to placebo.

Elderly patients with end-stage renal disease have to make a difficult decision whether or not to start dialysis. This study explores the considerations taken into account by these patients in decision-making regarding renal replacement therapy. In-depth interviews were conducted to gain an enhanced understanding of the considerations in treatment decision-making. Fourteen patients aged 65 years or older participated in the interviews, of whom 8 patients had made the decision to start, and 6 patients the decision to decline, dialysis. All participating patients had a variety of health problems, but appeared to have normal cognitive functions. Patients who declined dialysis were older and more often men and widow(er)s compared with patients who accepted dialysis. Patients chose to start dialysis because they enjoyed life, were not prepared to face the end of life, felt they had no other choice or had care-giving responsibilities for family members. Patients declined dialysis because of the speculated loss of autonomy, their age-associated decrease in vitality, distance from dialysis center and reluctance to think about the future. Results suggest that patients' decisions to decline or accept dialysis are not based on the effectiveness of the treatment, but rather on personal values, beliefs and feelings toward life, suffering and death, and the expected difficulties in fitting the treatment into their life.

To implement a "flipped classroom" model for a renal pharmacotherapy topic module and assess the impact on pharmacy students' performance and attitudes. Students viewed vodcasts (video podcasts) of lectures prior to the scheduled class and then discussed interactive cases of patients with end-stage renal disease in class. A process-oriented guided inquiry learning (POGIL) activity was developed and implemented that complemented, summarized, and allowed for application of the material contained in the previously viewed lectures. Students' performance on the final examination significantly improved compared to performance of students the previous year who completed the same module in a traditional classroom setting. Students' opinions of the POGIL activity and the flipped classroom instructional model were mostly positive. Implementing a flipped classroom model to teach a renal pharmacotherapy module resulted in improved student performance and favorable student perceptions about the instructional approach. Some of the factors that may have contributed to students' improved scores included: student mediated contact with the course material prior to classes, benchmark and formative assessments administered during the module, and the interactive class activities.

Genetics, Environment, and Diabetes-Related End-Stage Renal Disease in the Canary Islands

Aims: Type 1 and type 2 diabetes, complicated with renal disease, have a significantly higher incidence in the Canary Islands than in mainland Spain and other European countries. Present-day Canarian inhabitants consist of a mixed population with North African indigenous and European colonizer ancestors who have rapidly evolved from a rural to an urban life style. The aim of this work was to assess the possible role of genetic and environmental factors on diabetes-related end-stage renal disease incidence in the Canary Islands. Results: For both types of diabetes there is an ethnic susceptibility increased by diabetes family history. Whereas the Y-chromosome does not play a significant role, mitochondrial DNA (mtDNA) haplogroup differences point to a maternal origin for this ethnic predisposition, confirming susceptible and protective effects for haplogroups J and T, respectively. In addition, urban life style seems to be an additional risk factor for type 1 diabetes. Conclusions: The maternal ethnic predisposition to diabetes complicated with kidney disease detected in the Canary Islands signals mtDNA and X-chromosome markers as the best candidates to uncover the genetic predisposition to this disease.

Retrospective studies showed that online hemodiafiltration (OL-HDF) is associated with a risk reduction of mortality over standard hemodialysis (HD) in patients with end-stage renal disease. Until now, no information was available from prospective randomized clinical trials. A prospective, randomized, multicenter, open study was designed to be conducted in HD units from Catalonia (Spain). The aim of the study is to compare 3-year survival in prevalent end-stage renal disease patients randomized to OL-HDF or to continue on standard HD. The minimum sample size was calculated according to Catalonian mortality of patients on dialysis and assuming a risk reduction associated with OL-HDF of 35% (1-sided p<0.05 and a statistical power of 0.8) and a rate of dropout due to renal transplantation or loss to follow-up of 30%. From May 2007 to September 2008, 906 patients were included and randomized to OL-HDF (n=456) or standard HD (n=450). Demographics and analytical data at the time of randomization were not different between both groups of patients. Patients will be followed during a 3-year period. The present study will contribute to evaluating the benefit for patient survival of OL-HDF over standard HD.

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

The incidence of end-stage renal disease (ESRD) and its associated comorbidities such as diabetes and hypertension continue to increase as the population ages. As most ESRD patients qualify for Medicare coverage, the U.S. government initiated reforms of the payment system for dialysis facilities in an effort to decrease expenditures associated with ESRD reimbursement. The effects of reduced reimbursement rates, bundled payment options, and quality incentives on the current dialysis system, including kidney dialysis units, physicians, and patients, are examined.

Renal supportive care (RSC) is an important option for elderly individuals reaching end-stage renal disease; however, the frequency of RSC practice is very low among Asian countries. We evaluated the attitude, the knowledge, and the preference for specific topics concerning RSC among participants who worked in different medical professions in Taiwan. A cross-sectional questionnaire-based survey was employed. Healthcare personnel ( N  = 598) who were involved in caring for end-stage renal disease patients at more than 40 facilities in Taiwan participated in this study. Participants were asked about their motivation for learning about RSC, the topics of RSC they were most and least interested in, their willingness to provide RSC, and to rate their knowledge and perceived importance of different topics. The vast majority of respondents (81.9%) were self-motivated about RSC, among whom nephrologists (96.8%) and care facilitators (administrators/volunteers) (45%) exhibited the highest and the least motivation, respectively ( p  < 0.01). Overall, respondents indicated that they had adequate knowledge about the five pre-specified RSC topics between medical professions ( p  = 0.04). Medical professions and institutional size exerted significant influence on the willingness to provide RSC. Our results facilitate the understanding of the knowledge and attitude toward different RSC topics among varied medical professions, and can guide the design of RSC education content for healthcare personnel.

Primary hyperoxaluria type 1 (PH1) is a rare genetic disorder characterized by allelic and clinical heterogeneity. We aim to describe the presentation and full single-center experience of the management of PH1 patients bearing the mutation described in our community (I244T mutation+polymorphism P11L). Since 1983, 12 patients with recurrent renal lithiasis have been diagnosed with PH1 and renal failure in the Canary Islands, Spain. Diagnostic confirmation was based on the presence of oxalosis in undecalcified bone or kidney allograft biopsy, reduced alanine:glyoxylate aminotransferase activity in liver biopsy, and blood DNA analysis. Patients underwent different treatment modalities depending on individual clinical circumstances and therapeutic possibilities at the time of diagnosis: hemodialysis, isolated kidney, simultaneous liver-kidney, or pre-emptive liver transplantation. In all cases, the presentation of advanced renal disease was relatively late (>13 years) and no cases were reported during lactancy or childhood. The eight patients treated with hemodialysis or isolated kidney transplantation showed unfavorable evolution leading to death over a variable period of time. In contrast, the four patients undergoing liver transplantation (three liver+kidney and one pre-emptive liver alone) showed favorable long-term allograft and patient survival (up to 12 years follow-up). In conclusion, in this PH1 population, all bearing the I244T mutation, the development of end-stage renal disease was distinctive during late adolescence or adulthood. Our long-term results support pre-emptive liver transplantation at early stages of renal failure, and kidney-liver transplantation for those with advanced renal disease.

Targeted deletion of kidney glucose-6 phosphatase leads to nephropathy.

Renal failure is a major complication that arises with aging in glycogen storage disease type 1a and type 1b patients. In the kidneys, glucose-6 phosphatase catalytic subunit (encoded by G6pc) deficiency leads to the accumulation of glycogen, an effect resulting in marked nephromegaly and progressive glomerular hyperperfusion and hyperfiltration preceding the development of microalbuminuria and proteinuria. To better understand the end-stage nephropathy in glycogen storage disease type 1a, we generated a novel kidney-specific G6pc knockout (K-G6pc(-/-)) mouse, which exhibited normal life expectancy. After 6 months, K-G6pc(-/-) mice showed glycogen overload leading to nephromegaly and tubular dilation. Moreover, renal accumulation of lipids due to activation of de novo lipogenesis was observed. This led to the activation of the renin-angiotensin system and the development of epithelial-mesenchymal transition process and podocyte injury by transforming growth factor β1 signaling. The K-G6pc(-/-) mice developed microalbuminuria caused by the impairment of the glomerular filtration barrier. Thus, renal G6pc deficiency alone is sufficient to induce the development of the early-onset nephropathy observed in glycogen storage disease type 1a, independent of the liver disease. The K-G6pc(-/-) mouse model is a unique tool to decipher the molecular mechanisms underlying renal failure and to evaluate potential therapeutic strategies.

Management of Chronic Kidney Disease Patients in the Intensive Care Unit: Mixing Acute and Chronic Illness.

De Rosa, Silvia; Samoni, Sara; Villa, Gianluca; Ronco, Claudio

2017-01-01

Patients with chronic kidney disease (CKD) are at high risk for developing critical illness and for admission to intensive care units (ICU). 'Critically ill CKD patients' frequently develop an acute worsening of renal function (i.e. acute-on-chronic, AoC) that contributes to long-term kidney dysfunction, potentially leading to end-stage kidney disease (ESKD). An integrated multidisciplinary effort is thus necessary to adequately manage the multi-organ damage of those kidney patients and contemporaneously reduce the progression of kidney dysfunction when they are critically ill. The aim of this review is to describe (1) the pathophysiological mechanisms underlying the development of AoC kidney dysfunction and its role in the progression toward ESKD; (2) the most common clinical presentations of critical illness among CKD/ESKD patients; and (3) the continuum of care for CKD/ESKD patients from maintenance hemodialysis/peritoneal dialysis to acute renal replacement therapy performed in ICU and, vice-versa, for AoC patients who develop ESKD. © 2017 S.

Diabetes mellitus is the leading cause of end stage renal disease and is responsible for more than 40% of all cases in the United States. Several therapeutic interventions for the treatment of diabetic nephropathy have been developed and implemented over the past few decades with some degree of success. However, the renal protection provided by these therapeutic modalities is incomplete. More effective approaches are therefore urgently needed. Recently, several novel therapeutic strategies have been explored in treating DN patients including Islet cell transplant, Aldose reductase inhibitors, Sulodexide (GAC), Protein Kinase C (PKC) inhibitors, Connective tissue growth factor (CTGF) inhibitors, Transforming growth factor-beta (TGF-β) inhibitors and bardoxolone. The benefits and risks of these agents are still under investigation. This review aims to summarize the utility of these novel therapeutic approaches. PMID:23293752

A 57-year-old woman developed blindness during treatment for sarcoidosis-induced end-stage renal disease. An initial renal transplantation failed, and hemoaccess was maintained with multiple central catheters and upper extremity prosthetic arteriovenous grafts. A successful second transplantation eliminated her need for hemodialysis, but a right brachial to internal jugular graft remained patent. Progressive visual loss 2 years after transplantation prompted ophthalmic evaluation which initially revealed unilateral left optic nerve edema and visual loss, ultimately worsening over several months to no light perception in the left eye, 20/60 vision in the right eye, and bilateral papilledema. Arteriography demonstrated cerebral venous hypertension attributed to the functioning hemoaccess graft. Permanent graft occlusion normalized the papilledema, and visual field defects in the right eye and visual acuity returned to 20/20 in the right eye.

Role of Nuclear Factor Erythroid 2-Related Factor 2 in Diabetic Nephropathy

PubMed Central

Min, Xu; Xu, Xiaohong

2017-01-01

Diabetic nephropathy (DN) is manifested as increased urinary protein level, decreased glomerular filtration rate, and final renal dysfunction. DN is the leading cause of end-stage renal disease worldwide and causes a huge societal healthcare burden. Since satisfied treatments are still limited, exploring new strategies for the treatment of this disease is urgently needed. Oxidative stress takes part in the initiation and development of DN. In addition, nuclear factor erythroid 2-related factor 2 (Nrf2) plays a key role in the cellular response to oxidative stress. Thus, activation of Nrf2 seems to be a new choice for the treatment of DN. In current review, we discussed and summarized the therapeutic effects of Nrf2 activation on DN from both basic and clinical studies. PMID:28512642

Early detection of individuals with Type 2 diabetes mellitus or hypertension at risk for micro- or macroalbuminuria may facilitate prevention and treatment of renal disease. We aimed to discover plasma and urine metabolites that predict the development of micro- or macroalbuminuria. Patients with Type 2 diabetes (n = 90) and hypertension (n = 150) were selected from the community-cohort 'Prevention of REnal and Vascular End-stage Disease' (PREVEND) and the Steno Diabetes Center for this case-control study. Cases transitioned in albuminuria stage (from normo- to microalbuminuria or micro- to macroalbuminuria). Controls, matched for age, gender, and baseline albuminuria stage, remained in normo- or microalbuminuria stage during follow-up. Median follow-up was 2.9 years. Metabolomics were performed on plasma and urine. The predictive performance of a metabolite for albuminuria transition was assessed by the integrated discrimination index. In patients with Type 2 diabetes with normoalbuminuria, no metabolites discriminated cases from controls. In patients with Type 2 diabetes with microalbuminuria, plasma histidine was lower (fold change = 0.87, P = 0.02) and butenoylcarnitine was higher (fold change = 1.17, P = 0.007) in cases vs. controls. In urine, hexose, glutamine and tyrosine were lower in cases vs. controls (fold change = 0.20, P < 0.001; 0.32, P < 0.001; 0.51, P = 0.006, respectively). Adding the metabolites to a model of baseline albuminuria and estimated glomerular filtration rate metabolites improved risk prediction for macroalbuminuria transition (plasma integrated discrimination index = 0.28, P < 0.001; urine integrated discrimination index = 0.43, P < 0.001). These metabolites did not differ between hypertensive cases and controls without Type 2 diabetes.

Radioiodine (RAI) is a cornerstone in the treatment of Differentiated Thyroid Cancer (DTC). In patients on haemodialysis due to End-Stage Renal Disease (ESRD), it must be used cautiously, considering the renal clearance of this radionuclide. Also, the safety of the procedure and subsequent long-term outcome is still not well defined. In 2001, we described a dosimetric method and short-term results in three patients, with a good safety profile. We hypothesize that our method is safe in a long-term scenario without compromising the prognosis of both renal and thyroid disease. Descriptive-retrospective study. A systematic search was carried out using our clinical database from 2000 to 2014. DTC and radioiodine treatment while on haemodialysis. peritoneal dialysis. Final sample n=9 patients (n=5 males), age 48 years (median age 51 years males, 67 years female group); n=8 papillary thyroid cancer, n=1 follicular thyroid cancer; n=5 lymph node invasion; n=1 metastatic disease. Median RAI dose administered on haemodialysis 100mCi. 7.5 years after radioiodine treatment on haemodialysis, n=7 deemed free of thyroid disease, n=1 persistent non-localised disease. No complications related to the procedure or other target organs were registered. After 3.25 years, n=4 patients underwent successful renal transplantation; n=4 patients did not meet transplantation criteria due to other conditions unrelated to the thyroid disease or its treatment. One patient died due to ischemic cardiomyopathy (free of thyroid disease). Radioiodine treatment during haemodialysis is a long-term, safe procedure without worsening prognosis of either renal or thyroid disease. Copyright © 2015 Elsevier España, S.L.U. and SEMNIM.

End-stage renal disease (ESRD) is a risk after kidney donation. We sought, in a large cohort of kidney donors, to determine the causes of donor ESRD, the interval from donation to ESRD, the role of the donor/recipient relationship, and the trajectory of the estimated GFR (eGFR) from donation to ESRD. From 1/1/1963 thru 12/31/2015, 4030 individuals underwent living donor nephrectomy at our center, as well as ascertainment of ESRD status. Of these, 39 developed ESRD (mean age ± standard deviation [SD] at ESRD, 62.4 ± 14.1 years; mean interval between donation and ESRD, 27.1 ± 9.8 years). Donors developing ESRD were more likely to be male, as well as smokers, and younger at donation, and to have donated to a first-degree relative. Of donors with a known cause of ESRD (n = 25), 48% was due to diabetes and/or hypertension; only 2 from a disease that would have affected 1 kidney (cancer). Of those 25 with an ascertainable ESRD cause, 4 shared a similar etiology of ESRD with their recipient. Almost universally, thechange of eGFR over time was stable, until new-onset disease (kidney or systemic). Knowledge of factors contributing to ESRD after living kidney donation can improve donor selection and counseling, as well as long-term postdonation care. © 2018 The American Society of Transplantation and the American Society of Transplant Surgeons.

Intra-operative arterial vasospasm during pediatric renal transplantation is an urgent clinical situation resulting in end-organ ischemia, associated changes in parenchymal turgor and color, diminished flow on ultrasound, and if left untreated, allograft loss. We hypothesized that intra-operative intra-arterial injection of nitroglycerin would reverse vasospasm and improve renal perfusion. A three-yr-old girl with end-stage renal disease due to autosomal recessive polycystic kidney disease on peritoneal dialysis underwent deceased donor renal transplantation. After optimal immediate reperfusion and hemodynamic parameters, the kidney lost turgor and became mottled in appearance despite adequate hilar arterial and venous Doppler waveforms. Two aliquots of 40 μg (0.4 mL of a 100 μg/mL) nitroglycerin solution were injected directly into the renal artery 10 min apart. Nitroglycerin resulted in dramatic change in the consistency and appearance of the allograft. An improvement in renal blood flow was demonstrated by ultrasound after the second intra-arterial nitroglycerin injection with only a transient decrease in systemic arterial blood pressure. The child experienced normal allograft perfusion on serial postoperative ultrasounds, with a prompt decrease in serum creatinine and excellent diuresis. Intra-arterial nitroglycerin is a promising option for intra-operative arterial vasospasm during pediatric renal transplantation with objective improvement in blood flow and perfusion. © 2016 John Wiley & Sons A/S.

Klotho G-395-A gene polymorphism may impact children with end-stage renal disease (ESRD). We investigated the relevance of Klotho G-395-A on ESRD development and progression, and its relationship with evolution of cardiovascular complications in pediatric dialysis patients. Fifty-five children with chronic kidney disease (CKD) and seventy healthy children were genotyped for Klotho G-395A. Incidence of GA/AA genotypes and A allele were higher in ESRD patients compared with controls (54.5 vs. 7.1%, P < 0.001; 30.9 vs. 13.6%, P = 0.001, respectively). Also, children with GA/AA genotypes were 15.6 times more likely to develop ESRD than with GG genotype (95% CI 5.4-44.7, P < 0.001). A allele carriers have 2.8 times higher risk of developing ESRD than those with G allele (95% CI 1.5-5.35, P = 0.001). Also, the A allele could be considered a predictor of cardiovascular disease (CVD), as carriers have 161 times higher risk of cardiovascular complications than non-carriers (95% CI 21-1233, P < 0.001). All ESRD patients with CVD presented with left ventricular hypertrophy (LVH) and the frequency of A allele was significantly higher among ESRD children with LVH, whereas G allele frequency was significantly higher among ESRD children without LVH. The A allele of the G-395A Klotho gene polymorphism shows a significantly higher frequency among children with CKD and those with CVD and LVH. This mutant allele could be used as a risk marker for the development of ESRD as well as a predictor of CVD in these children.

Few educational resources have been developed to inform patients' renal replacement therapy (RRT) selection decisions. Patients progressing toward end stage renal disease (ESRD) must decide among multiple treatment options with varying characteristics. Complex information about treatments must be adequately conveyed to patients with different educational backgrounds and informational needs. Decisions about treatment options also require family input, as families often participate in patients' treatment and support patients' decisions. We describe the development, design, and preliminary evaluation of an informational, evidence-based, and patient-and family-centered decision aid for patients with ESRD and varying levels of health literacy, health numeracy, and cognitive function. We designed a decision aid comprising a complementary video and informational handbook. We based our development process on data previously obtained from qualitative focus groups and systematic literature reviews. We simultaneously developed the video and handbook in "stages." For the video, stages included (1) directed interviews with culturally appropriate patients and families and preliminary script development, (2) video production, and (3) screening the video with patients and their families. For the handbook, stages comprised (1) preliminary content design, (2) a mixed-methods pilot study among diverse patients to assess comprehension of handbook material, and (3) screening the handbook with patients and their families. The video and handbook both addressed potential benefits and trade-offs of treatment selections. The 50-minute video consisted of demographically diverse patients and their families describing their positive and negative experiences with selecting a treatment option. The video also incorporated health professionals' testimonials regarding various considerations that might influence patients' and families' treatment selections. The handbook was comprised of written words, pictures of patients and health care providers, and diagrams describing the findings and quality of scientific studies comparing treatments. The handbook text was written at a 4th to 6th grade reading level. Pilot study results demonstrated that a majority of patients could understand information presented in the handbook. Patient and families screening the nearly completed video and handbook reviewed the materials favorably. This rigorously designed decision aid may help patients and families make informed decisions about their treatment options for RRT that are well aligned with their values.

Background Lifetime risk estimates of chronic kidney disease (CKD) can motivate preventative behaviors at the individual level and forecast disease burden and health care utilization at the population level. Study Design Markov Monte Carlo model simulation study. Setting & Population Current U.S. black and white population. Model, Perspective, & Timeframe Markov models simulating kidney disease development, using an individual perspective and lifetime horizon. Outcomes Age-, sex- and race-specific residual lifetime risks of CKD stages 3a+ (eGFR<60 ml/min/1.73m2), 3b+ (eGFR<45 ml/min/1.73 m2), and 4+ (eGFR<30 ml/min/1.73m2), and end stage renal disease (ESRD). Measurements State transition probabilities of developing CKD and of dying prior to its development were modeled using: 1) mortality rates from National Vital Statistics Report, 2) mortality risk estimates from a 2-million person meta-analysis, and 3) CKD prevalence from National Health and Nutrition Examination Surveys. Incidence, prevalence, and mortality related to ESRD were supplied by the US Renal Disease System. Results At birth, the overall lifetime risks of CKD stages 3a+, 3b+, 4+, and ESRD were 59.1%, 33.6%, 11.5%, and 3.6%, respectively. Women experienced greater CKD risk yet lower ESRD risk than men; blacks of both sexes had markedly higher CKD stage 4+ and ESRD risk (lifetime risks for white men, white women, black men, and black women, respectively: 53.6%, 64.9%, 51.8%, and 63.6% [CKD stage 3a+]; 29.0%, 36.7%, 33.7%, and 40.2% [CKD stage 3b+]; 9.3%, 11.4%, 15.8%, and 18.5% [CKD stage 4+]; and 3.3%, 2.2%, 8.5%, and 7.8% [ESRD]). Risk of CKD increased with age, with approximately one-half of CKD stage 3a+ cases developing after 70 years of age. Limitations CKD incidence estimates were modeled from prevalence in the U.S. population. Conclusions In the U.S., the lifetime risk of developing CKD stage 3a+ is high, underscoring the importance of primary prevention and effective therapy to reduce CKD-related morbidity and mortality.

The aim of this study was to determine the effects of renin-angiotensin system (RAS) blockade maintenance on renal protection in chronic kidney disease (CKD) patients with hyperkalemia occurring during treatment with RAS blockade. CKD III or IV patients, who were prescribed with RAS blockers and also had hyperkalemia, were included. The study population was divided into two groups based on maintenance or withdrawal of RAS blocker. Renal outcomes (doubling of creatinine or end-stage renal disease) and incidence of hyperkalemia were compared between the two groups. Out of 258 subjects who developed hyperkalemia during treatment with RAS blockers, 150 (58.1%) patients continued on RAS blockades, while RAS blockades were discontinued for more than 3 months in the remaining 108 patients. Renal event-free survival was significantly higher in the maintenance group compared with the withdrawal group. Cox proportional hazard ratio for renal outcomes was 1.35 (95% CI: 1.08-1.92, p=0.04) in the withdrawal group compared with the maintenance group. However, the incidence of hyperkalemia and hyperkalemia-related hospitalization or mortality did not differ between the two groups. This study demonstrated that the maintenance of RAS blockade is beneficial for the preservation of renal function and relatively tolerable in patients with CKD and hyperkalemia occurring during treatment with RAS blockade. © The Author(s) 2014.

Among renal malignancies, renal cell carcinoma (RCC) accounts for 85% of cases. Stage is a relevant prognostic factor; 5-year survival ranges from 81% to 8% according to the stage of disease. The treatment is based on surgery and molecularly targeted therapy has emerged as a choice for metastatic disease. Retrospective study by reviewing the medical records of patients with RCC treated in the last 10 years at UNIFESP. The primary end point of this trial was to evaluate the overall survival (OS) of the patients. The secondary end point was to evaluate the progression-free survival (PFS) after nephrectomy. 118 patients with RCC were included. The mean age was 58.3 years, 61.9% men; nephrectomy was performed in 90.7%, clear cell was the histology in 85.6%, 44 patients were classified as stage IV at diagnosis. Among these, 34 had already distant metastasis. 29 patients were treated with sunitinib. The median OS among all patients was 55.8 months. The median PFS after nephrectomy was 79.1 months. Sarcomatoid differentiation HR29.74 (95% CI, 4.31-205.26), clinical stage IV HR1.94 (95% CI, 1.37-2.75) and nephrectomy HR0.32 (95% CI, 0.15-0.67) were OS prognostic factors. Sunitinib had clinical activity. Patients treated in our hospital achieved median OS compatible with literature. Nevertheless, this study has shown a high number of patients with advanced disease. For patients with advanced disease, treatment with sunitinib achieved median OS of 28.7 months, consistent with the literature.

The incidence of chronic kidney disease (CKD) in liver transplant recipients has been estimated to be from 18% to 28% at 10 yr after transplantation. As outcomes from liver transplantation continue to improve, long-term native kidney function in these recipients becomes more critical to patient survival. We analyzed 1151 adult, deceased-donor, single-organ primary liver transplantations performed at our center between 7/17/84 and 12/31/07. Analysis of renal function was performed on 972 patients with liver allograft survival >1 yr. Kaplan-Meier analysis revealed that 3%, 7%, and 18% of liver transplant recipients with allograft survival >1 yr developed end-stage renal disease (ESRD) at five, 10, and 20 yr, respectively. Significant independent risk factors for ESRD included dialysis during the transplant hospitalization, the stage of CKD at one yr, hypercholesterolemia, non-Caucasian race, and hepatitis C as the primary indication for liver transplantation. The initial immunosuppression of essentially all recipients was a calcineurin inhibitor-based regimen. Close, long-term follow-up of liver transplant recipients permits optimal management of liver allograft and native renal function and can lead to excellent long-term outcomes despite a calcineurin inhibitor-based immunosuppressive regimen. © 2013 John Wiley & Sons A/S.

We report a case of kidney transplantation from mother to son, both of whom were likely to have had an unrecognized renal variant phenotype of Fabry disease. The patient was a 54-year-old man, with an unknown primary cause of end stage renal disease. He had no notable past medical history, other than end stage renal disease. He underwent living-related kidney transplantation from his mother at age 40 years. Foam cells in the glomeruli were identified on histology assessment of a 0-hour allograft biopsy, with zebra bodies identified in the glomerular visceral epithelial cells by electron microscopy. These findings were indicative of Fabry disease in the donated kidney. As a definitive diagnosis of Fabry's disease could not be confirmed, enzyme replacement therapy was not initiated. Thirteen years after kidney transplantation, the patient underwent left nephrectomy for a left renal tumour, with pathological findings of clear cell carcinoma, foam cells and zebra bodies in the native kidney. Detailed examinations identified low α-galactosidase A activity and mutation of the α-Gal A gene, confirming a diagnosis of a renal variant phenotype of Fabry disease. Histology of several allograft biopsies performed over the 14 years from the time of kidney transplantation revealed only moderate interstitial fibrosis and tubular atrophy, with no evidence of disease progression on electron microscopy, despite the presence of zebra bodies in the glomerular visceral epithelial cells. © 2016 Asian Pacific Society of Nephrology.

Tissue Doppler echocardiography has been introduced as a useful tool to assess systolic myocardial function. In this study we sought to compare patients with end-stage renal disease (ESRD), with renal transplantations and control subjects with regard to tissue Doppler parameters. Thirty recipients with functional grafts of overall mean age 36 +/- 7 years included 24 men. An equal number of patients with ESRD of overall mean age 35 +/- 7 years included 20 men. A third cohort was comprised of 20 age- and gender matched control subjects. Tissue Doppler imaging from the septal and lateral mitral annulus of the left ventricle and free wall of the right ventricle was performed from a 4-chamber view. Mean systolic and diastolic blood pressures were similar among the groups during imaging. Peak systolic velocity (S wave) at the septal annulus was similar in control subjects and recipients. S waves were significantly lower among ESRD patients compared with recipients (10.3 +/- 2.1 vs 12.0 +/- 2.5 cm/s, P = .04, respectively). Isovolumic contraction velocity of the septum and the right ventricular wall were significantly lower in ESRD patients than recipients or controls: 10.2 +/- 2.6 vs 12.5 +/- 2.8 vs 11.4 +/- 1.8 cm/s for septal wall (P = .008) and 13.9 +/- 3.6 vs 17.9 +/- 5.1 vs 16.8 +/- 5.8, for right ventricle (P = .01). Systolic indices of tissue Doppler echocardiography in recipients demonstrated similar values as control subjects and increased values compared with ESRD patients. These results suggested improvement in systolic myocardial function following renal transplantation.

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)

Tumor necrosis factor alpha (TNF-alpha) antagonists are now widely used in the treatment of aggressive rheumatoid arthritis and are generally well tolerated. Although rare, they could induce systemic lupus erythematosus, glomerulonephritis, and antineutrophil cytoplasmic antibody associated systemic vasculitis. Tumor necrosis factor alpha antagonists associated glomerulonephritis usually subsides after discontinuation of the therapy and subsequent initiation of corticosteroids and immunosuppressive agents. Here we describe crescentic glomerulonephritis progression to end-stage renal disease in a patient following two doses of TNF-alpha antagonists for the treatment of reactive arthritis. To our knowledge, dialysis dependent permanent renal loss after TNF-alpha antagonists has not yet been reported. We suggest the renal function should be closely monitored in patients treated with TNF-alpha antagonists by rheumatologists.

Continuous arteriovenous haemofiltration to regulate hyperkalaemia during renal transplantation: a case report.

2006-11-01

Progressive hyperkalaemia is common in end stage renal disease patients waiting for renal transplantation. Ventricular tachycardia and ventricular fibrillation due to hyperkalaemia are life-threatening complications in these patients. In live and related renal transplant, after induction and anaesthesia, ventricular fibrillation and pulmonary oedema occurred. After immediate resuscitation by defibrillation and intravenous injection of adrenaline, the patient was put on continuous femoral arteriovenous haemofiltration (CAVH). This improved his pulmonary oedema, controlled hyperkalaemia and surgery could be completed uninterruptedly. After anaesthetising live and related kidney donor for nephrectomy, since it is not prudent to stop recipient surgery because of unforeseen complication, the authors wish to recommend CAVH as an alternative method to prevent life threatening cardiac complication of hyperkalaemia.

End-stage kidney disease (ESKD) is now a worldwide pandemic. In concert with this, ESKD in Libya has also increased exponentially in recent decades. This review aims to define the magnitude of and risks for this ESKD epidemic among Libyans as there is a dearth of published data on this subject. A systematic review was conducted by searching PubMed, EMBASE and Google scholar databases to identify all relevant papers published in English from 2003 to 2012, using the following keywords: end stage, terminal, chronic, renal, kidney, risk factors, Arab, North Africa and Libya. In 2003, the reported incidence of ESKD and prevalence of dialysis-treated ESKD in Libya were the same at 200 per million population (pmp). In 2007, the prevalence of dialysis-treated ESKD was 350 pmp, but the true incidence of ESKD was not available. The most recent published WHO data in 2012 showed the incidence of dialysis-treated ESKD had risen to 282 pmp and the prevalence of dialysis-treated ESKD had reached 624 pmp. The leading causes of ESKD were diabetic kidney disease (26.5 %), chronic glomerulonephritis (21.1 %), hypertensive nephropathy (14.6 %) and congenital/hereditary disease (12.3 %). The total number of dialysis centers was 40 with 61 nephrologists. Nephrologist/internist to patient ratio was 1:40, and nurse to patient ratio was 1:3.7. Only 135 living-related kidney transplants had been performed between 2004 and 2007. There were no published data on most macroeconomic and renal service factors. ESKD is a major public health problem in Libya with diabetic kidney disease and chronic glomerulonephritis being the leading causes. The most frequent co-morbidities were hypertension, obesity and the metabolic syndrome. In addition to provision of RRT, preventive strategies are also urgently needed for a holistic integrated renal care system.

Abstract The prevalence of pain has been reported to be >60–70% among patients with advanced and end-stage kidney disease. Although the underlying etiologies of pain may vary, pain per se has been linked to lower quality of life and depression. The latter is of great concern given its known association with reduced survival among patients with end-stage kidney disease. We herein discuss and update the management of pain in patients with chronic kidney disease with and without requirement for renal replacement therapy with the focus on optimizing pain control while minimizing therapy-induced complications.

Large retrospective studies of people with posterior urethral valves (PUV) have reported chronic renal insufficiency (CRI) in up to one third of the participants and end-stage renal failure in up to one quarter of them. Nadir creatinine (lowest creatinine during the first year following diagnosis) is the recognised prognostic indicator for renal outcome in PUV, the most commonly used cut-off being 1 mg/dl (88.4 umol/l). To conduct a statistical analysis of nadir creatinine in PUV patients in order to identify the optimal cut-off level as a prognostic indicator for CRI. Patients treated by endoscopic valve ablation at the present institution between 1993 and 2004 were reviewed. Chronic renal insufficiency was defined as CKD2 or higher. Statistical methods included receiver operating characteristic (ROC) curve analysis, Fisher exact test and diagnostic utility tests. Statistical significance was defined as P < 0.05. Nadir creatinine was identified in 96 patients. The median follow-up was 9.4 (IQR 7.0, 13.4) years. A total of 29 (30.2%) patients developed CRI, with nine (9.4%) reaching end-stage renal failure. On ROC analysis, Nadir creatinine was highly prognostic for future CRI, with an Area Under the Curve of 0.887 (P < 0.001). Renal insufficiency occurred in all 10 (100%) patients with nadir creatinine >88.4 umol/l compared with 19 of 86 (22.2%) patients with lower nadir creatinine (P < 0.001). As a test for future CRI, a nadir creatinine cut-off of 88.4 umol/l gave a specificity of 100%, but poor sensitivity of 34.5%. Lowering the cut-off to 75 umol/l resulted in improvement in all diagnostic utility tests (Table). All 14 (100%) patients with nadir creatinine >75 umol/l developed CRI, compared with 15 of 82 (18.3%) patients with lower nadir creatinine (P < 0.001). Sensitivity only approached 95% at 35 umol/l, at which level specificity was low (Table). Two out of 36 (5.6%) patients with nadir creatinine <35 umol/l developed CRI. Multivariate analysis found recurrent UTI (OR 4.733; CI 1.297-17.280) and nadir creatinine >75 umol/l (OR 48.988; CI 4.9-490.11) to be independent risk factors for progression to CRI. Using cut-off values of 35 umol/l and 75 umol/l, patients can be stratified into low-, intermediate- and high-risk groups, with development of CRI in 5.3%, 28.3% and 100%, respectively (P <0.001). The stage of CKD was higher in higher risk groups. Patients with nadir creatinine >75 umol/l (0.85 mg/dl) should be considered at high risk for CRI, while patients with nadir creatinine ≤35 umol/l (0.4 mg/dl) should be considered low risk. Patients with nadir creatinine between these two values have an intermediate risk of CRI. Copyright © 2015 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.

Three years later, she was referred to the surgeon with an abscess in the axillary region at the site of a previous arterio-venous (AV) graft. She underwent repeated incision and drainage of the abscess, which was constantly recurring. Nine months later, she presented with a tender swelling at the site of the AV graft with purulent discharge. The graft was removed; culture and histology confirmed the presence of tuberculosis (TB). This patient presents a rare case of TB infection in the AV graft.

Non-coding RNAs have gained increasing attention during the last decade. The first large group of non-coding RNAs to be characterized systematically starting at the beginning of the 21st century were small oligonucleotides--the so-called microRNAs (miRNAs). By now we have learnt that microRNAs are indispensable for most biological processes including organogenesis and maintenance of organ structure and function. The role of microRNAs has been studied extensively in the development of a number of organs, so far most studies focussed on e.g. the heart or the brain whilst the role of microRNAs in the development and maintenance of complex epithelial organs is less well understood. Furthermore most analyses regarding microRNA function in epithelial organs employed conditional knockout mouse models of the RNAse III Dicer to abrogate microRNA biogenesis. However, there is increasing evidence for Dicer to have multiple functions independent from microRNA maturation. Therefore Dicer independent models are needed to gain further insight into the complex biology of miRNA dependent processes. Here we analyze the contribution of microRNA-dependent transcriptional control in Pax8-expressing epithelial cells. Pax8 is a transcription factor that is crucial to the development of epithelial organs. The miRNA machinery was disrupted by crossing conditional DiGeorge syndrome critical region 8 (Dgcr8) fl/fl mice to Pax8Cre mice. The Dgcr8/Drosha complex processes pri-miRNAs in the nucleus before they are exported as pre-miRNAs for further maturation by Dicer in the cytoplasm. Dgcr8 fl/fl; Pax8Cre+ knockout mice died prematurely, developed massive hypothyroidism and end stage renal disease due to a loss of miRNAs in Pax8 expressing tissue. Pax8Cre-mediated conditional loss of DiGeorge syndrome critical region 8 (Dgcr8), an essential component of the nuclear machinery that is required for microRNA biogenesis, resulted in severe hypothyroidism, massively reduced body weight and ultimately led to renal failure and death of the animals. These data provide further insight into the importance of miRNAs in organ homeostasis using a Dicer independent model.

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

Prognosis and treatment of diabetic nephropathy: Recent advances and perspectives.

Approximately 20 to 40% of patients with type 1 or type 2 diabetes develop diabetic kidney disease. It is a clinical syndrome characterized by persistent albuminuria (>300mg/24h, or 300mg/g creatinine), a relentless decline in glomerular filtration rate, raised arterial blood pressure and enhanced cardiovascular morbidity and mortality. The natural course of classical diabetic nephropathy is initially microalbuminuria or moderately increased urine albumin excretion (30-300mg/g creatinine). Untreated microalbuminuria may then rise gradually, reaching severely increased albuminuric (macroalbuminuria) over 5 to 15 years. Glomerular filtration rate then begins to decline and end-stage renal failure is reached without treatment in 5 to 7 years. Regular, systematic screening for diabetic kidney disease is needed to identify patients at risk for, or with presymptomatic stages of diabetic kidney disease. Multifactorial intervention targeting glucose, lipids and blood pressure including blockade of renin angiotensin system and lifestyle, has improved renal and cardiovascular prognosis and reduced mortality with 50%. Recent data suggest beneficial pleiotropic effects on renal endpoint with new glucose lowering agents. It is also being investigated if blocking aldosterone could be an option as a potential new treatment. Thus, although diabetic nephropathy remains a major burden, prognosis has improved and new options for further improvements are currently tested in phase 3 clinical renal outcome studies.

Diabetic nepropathy (DN) is considered as the leading cause of end-stage renal disease (ESRD) worldwide, but the current available treatments are limited. Recent experimental evidences support the role of chronic microinflammation in the development of DN. Therefore, the tumor necrosis factor-alpha (TNF-α) pathway has emerged as a new therapeutic target for the treatment of DN. We investigated the nephroprotective effects of chrysin (5, 7-dihydroxyflavone) in a high fat diet/streptozotocin (HFD/STZ)-induced type 2 diabetic Wistar albino rat model. Chrysin is a potent anti-inflammatory compound that is abundantly found in plant extracts, honey and bee propolis. The treatment with chrysin for 16more » weeks post induction of diabetes significantly abrogated renal dysfunction and oxidative stress. Chrysin treatment considerably reduced renal TNF-α expression and inhibited the nuclear transcription factor-kappa B (NF-kB) activation. Furthermore, chrysin treatment improved renal pathology and suppressed transforming growth factor-beta (TGF-β), fibronectin and collagen-IV protein expressions in renal tissues. Chrysin also significantly reduced the serum levels of pro-inflammatory cytokines, interleukin-1beta (IL-1β) and IL-6. Moreover, there were no appreciable differences in fasting blood glucose and serum insulin levels between the chrysin treated groups compared to the HFD/STZ-treated group. Hence, our results suggest that chrysin prevents the development of DN in HFD/STZ-induced type 2 diabetic rats through anti-inflammatory effects in the kidney by specifically targeting the TNF-α pathway. - Highlights: • Chrysin reduced renal oxidative stress and inflammation in diabetic rats. • Chrysin reduced serum levels of pro-inflammatory in diabetic rats. • Chrysin exhibited renal protective effect by suppressing the TNF-α pathway.« less

BACKGROUND Living kidney donors face the risk of renal dysfunction, resulting in end-stage renal disease, cardiovascular disease, or cerebrovascular disease, after donor nephrectomy. Reducing this risk is important to increasing survival of living donors. In this study, we investigated the effect of preoperative distribution of abdominal adipose tissue and nutritional status on postoperative renal function in living donors. MATERIAL AND METHODS Seventy-five living donors were enrolled in this retrospective study. Preoperative unenhanced computed tomography images were used to measure abdominal adipose tissue parameters. Prognostic nutritional index (PNI) was used to assess preoperative nutritional status. Donors were divided into 2 groups according to abdominal visceral adipose tissue (VAT) area at the level of the fourth and fifth lumbar vertebrae (<80 or ≥80 cm²). Postoperative renal function was compared in the 2 groups, and prognostic factors for development of chronic kidney disease (CKD) G3b were identified using multivariate analysis. RESULTS Donors with a VAT area ≥80 significantly more often had hypertension preoperatively. Although there was no significant difference in preoperative estimated glomerular filtration rate (eGFR) between the 2 groups, postoperative renal function was significantly decreased in donors with a VAT area ≥80 compared to those with a VAT area <80. In multivariate analysis, VAT area ≥80 and PNI <54 were independent factors predicting the development of CKD G3b after 12 months. CONCLUSIONS Our findings suggest that preoperative VAT and PNI affect postoperative renal function. Further research is required to establish appropriate exercise protocols and nutritional interventions during follow-up to improve outcomes in living donors.

Early diagnosis of diabetic vascular complications: impairment of red blood cell deformability

NASA Astrophysics Data System (ADS)

Reduced deformability of red blood cells (RBCs) may play an important role on the pathogenesis of chronic vascular complications of diabetes mellitus. However, available techniques for measuring RBC deformability often require washing process after each measurement, which is not optimal for day-to-day clinical use at point of care. The objectives of the present study are to develop a device and to delineate the correlation of impaired RBC deformability with diabetic nephropathy. We developed a disposable ektacytometry to measure RBC deformability, which adopted a laser diffraction technique and slit rheometry. The essential features of this design are its simplicity (ease of operation and no moving parts) and a disposable element which is in contact with the blood sample. We studied adult diabetic patients divided into three groups according to diabetic complications. Group I comprised 57 diabetic patients with normal renal function. Group II comprised 26 diabetic patients with chronic renal failure (CRF). Group III consisted of 30 diabetic subjects with end-stage renal disease (ESRD) on hemodialysis. According to the renal function for the diabetic groups, matched non-diabetic groups were served as control. We found substantially impaired red blood cell deformability in those with normal renal function (group I) compared to non-diabetic control (P = 0.0005). As renal function decreases, an increased impairment in RBC deformability was found. Diabetic patients with chronic renal failure (group II) when compared to non-diabetic controls (CRF) had an apparently greater impairment in RBC deformability (P = 0.07). The non-diabetic cohort (CRF), on the other hand, manifested significant impairment in red blood cell deformability compared to healthy control (P = 0.0001). The newly developed slit ektacytometer can measure the RBC deformability with ease and accuracy. In addition, progressive impairment in cell deformability is associated with renal function loss in all patients regardless of the presence or absence of diabetes. In diabetic patients, early impairment in RBC deformability appears in patients with normal renal function.

Ethical and legal issues in renal transplantation in Nigeria.

Ajayi, S O; Raji, Y; Salako, B L

2016-01-01

With the increasing number of patients being offered kidney transplantation by many centers in the developing world, it is not unexpected that there would be attendant ethical and legal issues even when the selection process for transplantation seems medically justified. Because of the inadequate infrastructure for hemodialysis and peritoneal dialysis, coupled with the challenges of logistics for maintenance dialysis, transplantation would seem to be the best option for patients with end-stage renal failure, even in developed economies where these can easily be tackled. The main issues here revolve around incentives for donors, organ trade and trafficking and the economics of eliminating the waiting list and the criminal activities of organ trans-plantation. In the developing world, with the current level of corruption and poverty, there is a need to redouble efforts to monitor transplant activities. Professional bodies should take the lead in this regard. Furthermore, there is a need for governments to engage in public consultation and community awareness concerning organ donation in living and deceased persons.

This study was designed to assess dialysis subjects’ perceived autonomy support association with phosphate binder medication adherence, race and gender. A multi-site cross-sectional study was conducted among 377 dialysis subjects. The Health Care Climate (HCC) Questionnaire assessed subjects’ perception of their providers’ autonomy support for phosphate binder use, and adherence was assessed by the self-reported Morisky Medication Adherence Scale (MMAS). Serum phosphorus was obtained from the medical record. Regression models were used to examine independent factors of medication adherence, serum phosphorus, and differences by race and gender. Non-white HCC scores were consistently lower compared with white subjects’ scores. No differences were observed by gender. Reported phosphate binder adherence was associated with HCC score, and also with phosphorus control. No significant association was found between HCC score and serum phosphorus. Autonomy support, especially in non-white end stage renal disease subjects, may be an appropriate target for culturally informed strategies to optimize mineral bone health. PMID:27167227

The objective of this study was to investigate the prevalence of antibodies to hantaviruses among hemodialysis patients with end-stage renal failure in Kaunas and its district. Serums of 218 patients from four dialysis centers of Kaunas district were tested by using the immunoglobulin G antibody-capture enzyme-linked immunosorbent assay (ELISA). The reactivity of ELISA-positive sera was proven in Western blot tests using various hantavirus recombinant nucleocapsid proteins. The yeast-expressed nucleocapsid proteins were used for testing. Antibodies against Dobrava/Hantaan and Puumala hantaviruses were found in 16 patients (seroprevalence 7.4%). Most of the sera were positive for Dobrava hantavirus (81%). The ratio of males to females was 1.2:1. Seroprevalence was significantly higher in older patients. Results indicate that antibodies to two hantaviruses (Dobrava/Hantaan virus and Puumala virus) are prevalent among hemodialysis patients in Kaunas district with approximately the same seroprevalence as in neighboring countries.

Quantifying and estimating the predictive accuracy for censored time-to-event data with competing risks.

This paper focuses on quantifying and estimating the predictive accuracy of prognostic models for time-to-event outcomes with competing events. We consider the time-dependent discrimination and calibration metrics, including the receiver operating characteristics curve and the Brier score, in the context of competing risks. To address censoring, we propose a unified nonparametric estimation framework for both discrimination and calibration measures, by weighting the censored subjects with the conditional probability of the event of interest given the observed data. The proposed method can be extended to time-dependent predictive accuracy metrics constructed from a general class of loss functions. We apply the methodology to a data set from the African American Study of Kidney Disease and Hypertension to evaluate the predictive accuracy of a prognostic risk score in predicting end-stage renal disease, accounting for the competing risk of pre-end-stage renal disease death, and evaluate its numerical performance in extensive simulation studies.

Risk factors for selective cognitive decline in dialyzed patients with end-stage renal disease: evidence from verbal fluency analysis.

PubMed

2012-01-01

Although dialyzed patients often have cognitive problems, little is known about the nature of these deficits. We hypothesized that, in contrast to semantic fluency relying mainly on temporal lobes, phonemic fluency, preferentially depending on functions of frontal-subcortical systems, would be particularly sensitive to the constellation of physiological pathological processes associated with end-stage renal disease and dialysis. Therefore, we longitudinally compared phonemic and semantic fluency performance between 49 dialyzed patients and 30 controls. Overall, patients performed below controls only on the phonemic fluency task. Furthermore, their performance on this task declined over time, whereas there was no change in semantic fluency. Moreover, this decline was related to the presence of hypertension and higher blood urea nitrogen. We suggest that these findings may be due to a combination of vascular and topic effects that impact more on fronto-subcortical than temporal lobe networks, but this speculation requires direct confirmation.

Nursing Intervention on the Compliance of Hemodialysis Patients with End-Stage Renal Disease: A Meta-Analysis.

Dialysis is imperative for patients with end-stage renal disease (ESRD); however, compliance ensures its efficacy. Nursing intervention has been considered to improve compliance. This meta-analysis is aimed at exploring the effects of nursing intervention on dialysis compliance. A search was performed in the PubMed, Cochrane, and Embase databases for relevant original research articles. Studies were included or excluded based on the simultaneous consideration of quality as ranked by Jadad score and the compliance with predefined selection criteria. A total of 817 participants were included. The results showed that nursing intervention led to significantly higher compliance with dialysis than in standard care. A pilot analysis evidenced that different intervention strategies, including educational, cognitive, and behavioral approaches, had limited effects on dialysis compliance. Nursing intervention is beneficial for raising dialysis compliance, providing evidence of the need to strengthen nursing care for ESRD patients administered with dialysis in daily clinical practice. © 2017 S.

Medicare’s Payment Strategy For End-Stage Renal Disease Now Embraces Bundled Payment And Pay-For-Performance To Cut Costs

Since 1973 Medicare has provided health insurance coverage to all people who have been diagnosed with end-stage renal disease, or kidney failure. In this article we trace the history of payment policies in Medicare’s dialysis program from 1973 to 2011, while also providing some insight into the rationale for changes made over time. Initially, Medicare adopted a fee-for-service payment policy for dialysis care, using the same reimbursement standards employed in the broader Medicare program. However, driven by rapid spending growth in this population, the dialysis program has implemented innovative payment reforms, such as prospective bundled payments and pay-for-performance incentives. It is uncertain whether these strategies can stem the increase in the total cost of dialysis to Medicare, or whether they can do so without adversely affecting the quality of care. Future research on the intended and unintended consequences of payment reform will be critical. PMID:22949455

Autophagy: A Novel Therapeutic Target for Diabetic Nephropathy.

PubMed

Kume, Shinji; Koya, Daisuke

2015-12-01

Diabetic nephropathy is a leading cause of end stage renal disease and its occurance is increasing worldwide. The most effective treatment strategy for the condition is intensive treatment to strictly control glycemia and blood pressure using renin-angiotensin system inhibitors. However, a fraction of patients still go on to reach end stage renal disease even under such intensive care. New therapeutic targets for diabetic nephropathy are, therefore, urgently needed. Autophagy is a major catabolic pathway by which mammalian cells degrade macromolecules and organelles to maintain intracellular homeostasis. The accumulation of damaged proteins and organelles is associated with the pathogenesis of diabetic nephropathy. Autophagy in the kidney is activated under some stress conditions, such as oxidative stress and hypoxia in proximal tubular cells, and occurs even under normal conditions in podocytes. These and other accumulating findings have led to a hypothesis that autophagy is involved in the pathogenesis of diabetic nephropathy. Here, we review recent findings underpinning this hypothesis and discuss the advantages of targeting autophagy for the treatment of diabetic nephropathy.

The dialysis delivered after a chronic kidney disease (CDK) or any otherwise severe end-stage renal failure is a complex medical task, leading to major medical and psychopathological distress for the patient. The aim of the present study was to analyze the impact of the dialysis experience on the nephrologic patient's global quality of life. In the present cross-sectional study, involving 96 patients with end-stage renal disease receiving hemodialysis, demographic, medical, and psychological differential features across different CDK diagnoses were accounted and were then correlated each other. Among other differential features, the "acknowledgement of dependence" (from the medical device delivering the dialysis) emerged as a factor correlated to "self-sufficiency" in CDK patients receiving hemodialysis. Although further, larger-sampled studies on the topic are needed, medical and psychological interventions are useful to ensure a better global quality of life and good therapeutic adherence in dialysis patients.

Renal tubulointerstitial fibrosis is the common and final pathologic change of kidney in end-stage renal disease. Interesting, endoplasmic reticulum (ER) stress is known to contribute to the pathophysiological mechanisms during the development of renal fibrosis. Here, we investigated the effects of chemical chaperon sodium 4-phenylbutyrate (4-PBA) on renal fibrosis in vivo and in vitro. In a rat unilateral ureteral obstruction (UUO) model, 4-PBA mimicked endogenous ER chaperon in the kidneys and significantly reduced glucose regulated protein 78 (GRP78), CCAAT/enhancer binding protein (C/EBP) homologous protein (CHOP), activating transcription factor 4 (ATF4), and phosphorylated JNK protein expressions as well as restored spliced X-box-binding protein 1 (XBP1) expressions in the kidneys of UUO rats. 4-PBA also attenuated the increases of α-smooth muscle actin (α-SMA), connective tissue growth factor (CTGF) protein expressions, tubulointerstitial fibrosis, and apoptosis in the kidneys of UUO rats. Moreover, transforming growth factor (TGF)-β markedly increased ER stress-associated molecules, profibrotic factors, and apoptotic markers in the renal tubular cells (NRK-52E), all of which could be significantly counteracted by 4-PBA treatment. 4-PBA also diminished TGF-β-increased CTGF promoter activity and CTGF mRNA expression in NRK-52E cells. Taken together, our results indicated that 4-PBA acts as an ER chaperone to ameliorate ER stress-induced renal tubular cell apoptosis and renal fibrosis.

Sustainable and tenable renal health model: a Latin American proposal of classification, programming, and evaluation.

Calderón, Rafael Burgos; Depine, Santos

End-stage renal disease (ESRD) presents a major problem to public health, with complex implications for social and economic structures in every nation of the world. Clearly, Latin American and Caribbean countries are not able to meet the needs of every patient requiring dialysis treatment at ESRD. Consequently, a considerable number of patients die every year as a result of lack of resources. Aware of this serious social, ethical, and economic problem, the Latin American Society of Nephrology and Hypertension proposed a new renal health concept in the region. In December 2002, at the workshop in Valdivia, Chile, a modification to the National Kidney Foundation Classification of Chronic Kidney Disease was approved. According to modifications to the concept of chronic kidney disease approved in the Declaration of Valdivia, a new Renal Health Model was proposed. It consists of including orderly follow-up in patients' charts, starting from the earliest stage, and a model establishing a guideline for the reallocation of financial resources to guarantee continuity of treatment to patients with ESRD. The implementation of the Renal Health Program in health ministries of Latin American and Caribbean countries would allow for a substantial improvement in renal health prevention and management, as a result of better distribution of financial and human resources.

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.

Advanced glycation end products (AGE) and dicarbonyl compounds accumulate in serum and tissues of patients with diabetes and chronic renal failure. Pentosidine, free pentosidine, glyoxal and methylglyoxal have been evaluated in plasma of diabetic patients with poor metabolic control at baseline and after the improvement of glycemic levels, and in plasma and peritoneal dialysate of patients with renal failure before and after 12 h of peritoneal dialysis. In diabetic patients, acceptable metabolic control was unable to normalize levels of pentosidine (after 2 and 10 months), glyoxal and methylglyoxal (after 2 months). In patients with end-stage renal disease, mean values of pentosidine, free pentosidine, glyoxal and methylglyoxal decreased in plasma after dialysis. No pentosidine or free pentosidine were present in the peritoneal dialysate at time 0, but were found after 12 h of peritoneal dialysis; glyoxal and methylglyoxal decreased after 12 h of dialysis. So, glyoxal and methylglyoxal, already present in the dialysis fluid, can react with the peritoneal matrix protein, giving a reason for the gradual loss of peritoneal membrane function often observed in patients undergoing long-term peritoneal dialysis.

To facilitate planning, national renal registries provide reliable and up-to-date information on numbers of patients with end-stage renal disease (ESRD), developing trends, treatment modalities, and outcomes. To that end, the present publication represents the first official report from Iranian Peritoneal Dialysis Registry. The prevalence, demographics, and clinical characteristics of patients on peritoneal dialysis (PD) were collected from all PD centers throughout the country. By the end of 2009, the prevalence of ESRD was 507 per million population in Iran. The most common renal replacement modality was hemodialysis (51.2%), followed by kidney transplantation (44.7%), and then PD (4.1%). The mean age of PD patients was 46 years, and the most common causes of ESRD were diabetes (33.5%), hypertension (24.4%), and glomerulonephritis (8.2%). Overall patient mortality was 25%, with cardiac events (46%), cerebral stroke (10%), and infection (8%) being the main causes of death. The 1-, 3-, and 5-year survivals were 89%, 64%, and 49% respectively. The most common cause of dropout was peritonitis (17.6%). Staphylococcus (coagulase-negative and S. aureus) was the most prevalent causative organism in peritonitis episodes; however, in more than 50% of episodes, a sterile culture was reported. Mean baseline serum hemoglobin and albumin were 10.7 g/dL and 3.6 g/dL respectively. Our registry results, representing the second largest report of PD in the Middle East, is almost comparable to available regional data. We hope that, in future, we can improve our shortcomings and lessen the gap with developed countries. Copyright © 2014 International Society for Peritoneal Dialysis.

In this review, we outline the rationale for expanding the role of palliative care in end-stage renal disease (ESRD), describe the components of a palliative care model, and identify potential barriers in implementation. Patients receiving chronic dialysis have reduced life expectancy and high rates of chronic pain, depression, cognitive impairment, and physical disability. Delivery of prognostic information and advance care planning are desired by patients, but occur infrequently. Furthermore, although hospice care is associated with improved symptom control and lower healthcare costs at the end of life, it is underutilized by the ESRD population, even among patients who withdraw from dialysis. A palliative care model incorporating communication of prognosis, advance care planning, symptom assessment and management, and timely hospice referral may improve quality of life and quality of dying. Resources and clinical practice guidelines are available to assist practitioners with incorporating palliative care into ESRD management. There is a large unmet need to alleviate the physical, psychosocial, and existential suffering of patients with ESRD. More fully integrating palliative care into ESRD management by improving end-of-life care training, eliminating structural and financial barriers to hospice use, and identifying optimal methods to deliver palliative care are necessary if we are to successfully address the needs of an aging ESRD population.
