Peritoneal dialysis technique success during the initial 90 days of therapy.

Comparisons of technique success by peritoneal dialysis (PD) modality have typically excluded the initial 90 days of therapy. We analyzed a database of 51,469 new PD starts from 2004 to 2008 in the United States. The analysis concentrated on the initial 90 days of therapy to determine technique success and the impact of the continuous ambulatory PD (CAPD) and automated PD (APD) modalities.

Mutations in kelch-like 3 and cullin 3 cause hypertension and electrolyte abnormalities.

Hypertension affects one billion people and is a principal reversible risk factor for cardiovascular disease. Pseudohypoaldosteronism type II (PHAII), a rare Mendelian syndrome featuring hypertension, hyperkalaemia and metabolic acidosis, has revealed previously unrecognized physiology orchestrating the balance between renal salt reabsorption and K(+) and H(+) excretion. Here we used exome sequencing to identify mutations in kelch-like 3 (KLHL3) or cullin 3 (CUL3) in PHAII patients from 41 unrelated families.

Relationship between drain volume/fill volume ratio and clinical outcomes associated with overfill complaints in peritoneal dialysis patients.

Background: To better understand the spectrum of overfill reports and their corresponding clinical severity and etiology, we conducted a review of overfill reports from the Manufacturer and User Facility Device Experience (MAUDE) database, which is within the Food and Drug Administration (FDA) Web site (www.fda.gov).

A new, safe and convenient 5-L dual-chamber container for automated peritoneal dialysis.

Background: Automated peritoneal dialysis (APD) provides the opportunity for home-based dialysis, enabling the patient to optimize their lifestyle by maintaining their normal daily routine. Use of a larger bag size and biocompatible solution is desirable. In an effort to further improve patient convenience and reduce the probability of infusing only the buffer contents from the outflow chamber, we designed a 5-L dual-chamber container system with a dual-seal system consisting of a long seal between the dextrose chamber and buffer chambers and a short SafetyMoon™ seal between the buffer chamber and container outflow connector.

Sleep disturbances in children and adolescents with non-dialysis-dependent chronic kidney disease.

Background: While studies have shown sleep disorders to be common in adults with chronic kidney disease (CKD), pediatric data are scarce.

Objective: To characterize the prevalence of sleep disorders among children and adolescents with non-dialysis-dependent CKD.

Design: Prospective, questionnaire-based, cross-sectional study.

Urolithiasis with topiramate in nonambulatory children and young adults.

Urolithiasis occurs infrequently in the pediatric population, where metabolic factors play a primary role in the pathogenesis of stone formation. Topiramate, an antiepileptic drug, is associated with a kidney stone in 1.5% of patients in published clinical trials.

Sleep disturbances in pediatric dialysis patients.

Sleep disorders are common in adult dialysis patients, with a prevalence of 60%-80%. To date, sleep disturbances have not been assessed in the pediatric dialysis population. Therefore, the objective of this study is to describe the prevalence of sleep disturbance symptoms in a pediatric dialysis population.

Survival of childhood polycystic kidney disease following renal transplantation: the impact of advanced hepatobiliary disease.

Childhood PKD encompasses the diagnoses of AR and ADPKD, glomerulocystic disease, and syndromes such as tuberous sclerosis or Jeune's syndrome. Given the fact that a majority of PKD children with ESRD carry the diagnosis of ARPKD, natural history studies assessing the long-term prognosis of PKD patients following renal transplantation must focus on morbidity and mortality issues related to complications from congenital hepatic fibrosis. Using the NAPRTCS registry, we analyzed the patient and graft survival rates of 203 PKD patients and 7044 non-PKD patients undergoing renal transplantation between 1987 and 2001.

Effect of the peritoneal dialysis prescription on pentosidine in children.

Enhanced formation of advanced glycation end products (AGEs) by peritoneal dialysate containing high dextrose concentrations has been implicated as a source of peritoneal membrane toxicity and loss of viability in patients treated with peritoneal dialysis (PD). The goal of this project was to elucidate the relationship between the structurally defined AGE pentosidine accumulation on peritoneal and plasma proteins and peritoneal membrane function, and to identify clinical factors leading to alterations in these parameters. The study comprised 27 pediatric patients (14 continuous ambulatory PD, 13 chronic cycling PD) on PD for a mean duration of 37.

Complications of peritoneal dialysis in children with Eagle-Barrett syndrome.

Eagle Barrett syndrome (EBS) is characterized by the triad of abdominal muscle deficiency, urinary tract abnormalities, and cryptorchidism. Approximately 25% of patients with EBS progress to end-stage renal disease. It is speculated that the abdominal muscular defects in EBS pose technical problems in achieving successful peritoneal dialysis (PD).
