Peritoneal Dialysis, CAPD vs APD

INTRODUCTION: It is still controversial whether automated peritoneal dialysis (APD) or hemodialysis (HD) is a more favorable choice for the rapid initiation of peritoneal dialysis (PD). METHODS: A pilot randomized prospective controlled trial was carried out in Shanghai Ruijin Hospital. Sixty-seven patients who chose long-term PD treatment and needed unplanned dialysis were enrolled and randomized into HD-CAPD group (33 cases) or APD-CAPD group (34 cases) based on the dialysis modality during the transition period (within 14 days from the day PD catheter was implanted)...

INTRODUCTION: To achieve optimal blood pressure control in continuous ambulatory peritoneal dialysis (CAPD) patients, identifying methods of volume assessment with the strongest correlation with blood pressure is essential. METHODS: In this cross-sectional study, 52 CAPD patients were assigned to automated office blood pressure (AOBP) measurement, assessment of pedal pitting edema, bioimpedance analysis (BIA), and inferior vena cava collapsibility index (IVCCI%) measurement...

BACKGROUND: Incremental peritoneal dialysis (PD) is increasingly advocated to reduce treatment burden and costs, with potential to better preserve residual kidney function. Global prevalence of incremental PD use is unknown and use in Australia and New Zealand has not been reported. METHODS: Binational registry analysis including incident adult PD patients in Australia and New Zealand (2007-2017), examining incidence of and outcomes associated with incremental PD (first recorded PD exchange volume <42 L/week (incremental) vs...

BACKGROUND: Incremental peritoneal dialysis (PD) can be defined as a PD prescription that is less than the standard, full dose prescription and is typically used for patients initiating PD with residual kidney function. It has been suggested that use of incremental peritoneal dialysis may help preserve residual kidney function and may offer better quality of life due to the lower treatment burden, however published evidence is limited. In this study we assessed the associations between incremental peritoneal dialysis use and both clinical outcomes and quality of life measures in a large cohort of incident peritoneal dialysis patients in the US...

INTRODUCTION: Although vascular calcification is a recognised complication for haemodialysis patients, peritoneal dialysis (PD) patients are also at risk. As such we wished to review peritoneal and urinary calcium balance and the effect of calcium containing phosphate binders (CCPBs). METHODS: Twenty-four-hour peritoneal calcium balance and urinary calcium were reviewed in PD patients undergoing their first assessment of peritoneal membrane function. RESULTS: Results from 183 patients, 56...

BACKGROUND: Previous studies investigating hospitalizations in dialysis patients have focused primarily on patient-centered factors. We analyzed the impact of hospital and dialysis unit characteristics on pediatric dialysis patients' hospitalizations for access-related complications (ARCs). METHODS: This cross-sectional study involved 102 hemodialysis (HD) and 163 peritoneal dialysis (PD) patients. Data between July 2017 and July 2018 were analyzed. RESULTS: Children's hospitals (CHs) had more pediatric nephrologists and longer PD experience (years) than general hospitals (GHs) (p = 0...

INTRODUCTION: Incremental peritoneal dialysis (IPD) is based on the prescription of a dose lower than the standard (SPD). The combination of residual kidney function (RKF) and peritoneal clearance achieves clearance goals. The aim of this study is to compare the outcomes of IPD with SPD. MATERIALS AND METHODS: This was a single-center, retrospective study that included a cohort of prevalent peritoneal dialysis (PD) adults. Patients were assigned according to their first PD protocol in two groups - group A: IPD protocol (continuous ambulatory PD: less than 4 dwells daily, less than 2 L dwell volume, and/or treatment less than 7 days/week; automated PD: without a long dwell, less than 10 L daily delivered, and/or treatment for less than 7 days/week); group B: SPD protocol...

BACKGROUND: For patients on peritoneal dialysis (PD), the deleterious effects of high concentrations of dialysate glucose on the peritoneal membrane are well-documented. Systemic effects of peritoneally absorbed glucose are more poorly defined. Using continuous glucose monitoring (CGM), we aimed to describe 24-h glycaemic profiles of PD patients without diabetes and compare with non-dialysis controls with stage 5 chronic kidney disease (CKD-5). METHODS: In this cross-sectional, case-control study, 15 patients on PD (9 automated PD (APD) and 6 continuous ambulatory PD (CAPD)) and 16 CKD-5 controls underwent 72 h of CGM and metabolic profiling...

BACKGROUND: Incremental peritoneal dialysis (PD) is recommended as a component of high-quality care by the international society for PD; however, its feasibility and clinical outcomes have not been widely reported. The aim of this study is to describe our experience with incremental PD. METHODS: This was a retrospective cohort study of incident PD patients at Eastern Health between 2015 and 2019. Patients who stopped PD within 30 days were excluded. Incremental PD was defined in CAPD as using <8 L/day of exchange volume and in automated PD as dialysing without a last fill...

BACKGROUND: Regeneration of peritoneal dialysis (PD) fluid using sorbent technology can provide flexibility and improve quality of life. This study examined the safety and efficacy of the automated wearable artificial kidney (AWAK) device in PD patients. METHODS: This pilot study included prevalent PD patients from a single center in Singapore between 2016 and 2018. Participants underwent up to nine AWAK therapies over 72 h and were followed up for 1 month. Primary outcomes were serious adverse events (SAEs) and completion of nine therapies without device deficiency...

BACKGROUND: Fluid overload (FO) in peritoneal dialysis (PD) patients is associated with mortality. We explore if low daily sodium removal is an independent risk factor for mortality. We examined severely FO PD patients established for >1 year in expectation that PD prescription would have been optimized for solute clearance and ultrafiltration. We also wish to determine the relationship between kt/v and sodium removal. METHODS: Retrospective analysis of 231 PD patients with FO ≥2...

Prior studies have associated automated peritoneal dialysis (APD) with less effective volume and blood pressure (BP) control as compared with continuous ambulatory peritoneal dialysis (CAPD). Our study aimed to compare the volume status, ambulatory BP profile and severity of arterial stiffness between patients treated with CAPD versus APD. In a case-control design, 28 CAPD patients were matched in 1:1 ratio with 28 controls receiving APD for age, gender and diabetic status. Body composition was assessed with the method of bioimpendence spectroscopy...

Sodium removal in peritoneal dialysis (PD) depends on convective clearance, typically generated by a glucose gradient, but this can result in glucose absorption. We wished to determine which factors determine peritoneal sodium losses to glucose absorption (PD Na/Gluc). Peritoneal sodium losses and glucose absorption were calculated from measured 24-h collections of PD effluent, in patients attending for assessment of peritoneal membrane function. Five hundred and fifty eight patients; 317 (56.8%) males, mean age 56...

OBJECTIVE: The aim of this study was to report the prevalence of peritonitis and mortality in patients with end-stage kidney disease (ESKD) treated with chronic peritoneal dialysis (PD) in Africa. DESIGN: Systematic review. SETTING: Africa. PARTICIPANTS: Patients with ESKD in Africa. INTERVENTIONS: PD in its varied forms. PRIMARY AND SECONDARY OUTCOMES: PD-related peritonitis rate (primary outcome), time-to-discontinuation of PD, mortality...

In renal failure, hyperphosphatemia is common and correlates with increased mortality making phosphate removal a key priority for dialysis therapy. We investigated phosphate clearance, removal and serum level, and factors associated with phosphate control in patients undergoing continuous ambulatory (CAPD), continuous cyclic (CCPD) and automated (APD) peritoneal dialysis (PD). In 154 prevalent PD patients (mean age 53.2 ± 17.6 year, 59% men, 47% anuric), 196 daily collections of urine and 368 collections of dialysate were evaluated in terms of renal, peritoneal and total (renal plus peritoneal) phosphorus removal (g/week), phosphate and creatinine clearances (L/week) and urea KT/V...

BACKGROUND: This retrospective cohort study compared patient survival and technique survival between patients on continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD) using recent data at a single tertiary medical center in Taiwan. METHODS: From medical records, we identified incident 459 CAPD patients and 266 APD patients on dialysis for at least 90 days and aged more than 18 years to estimate mortality and technique failure rates, and related hazard ratio (HR) and 95% confidence interval (CI) from 2007 to 2018...

Peritoneal dialysis (PD) offers specific advantages over hemodialysis, enabling increased autonomy of patients with end-stage renal disease, but PD-related complications need to be detected in a timely manner. Fourier transform infrared (FTIR) spectroscopy could provide rapid and essential insights into the patients' risk profiles via molecular fingerprinting of PD effluent, an abundant waste material that is rich in biological information. In this study, we measured FTIR spectroscopic profiles in PD effluent from patients taking part in a randomized controlled trial of alanyl-glutamine addition to the PD-fluid...

BACKGROUND: In Japan, the medical expenditures associated with dialysis have garnered considerable interest; however, a cost-effectiveness evaluation of peritoneal dialysis (PD) is yet to be evaluated. In particular, the health economics of the "PD first" concept, which can be advantageous for clinical practice and healthcare systems, must be evaluated. METHODS: This multicenter study investigated the cost-effectiveness of PD. The major effectiveness indicator was quality-adjusted life year (QALY), with a preference-based utility value based on renal function, and the cost indicator was the amount billed for a medical service at each medical institution for qualifying illnesses...

BACKGROUND: Optimal fluid balance for peritoneal dialysis (PD) patients requires both water and sodium removal. Previous studies have variously reported that continuous ambulatory peritoneal dialysis (CAPD) removes more or equivalent amounts of sodium than automated PD (APD) cyclers. We therefore wished to determine peritoneal dialysate losses with different PD treatments. METHODS: Peritoneal and urinary sodium losses were measured in 24-h collections of urine and PD effluent in patients attending for their first assessment of peritoneal membrane function...

BACKGROUND: The aim of this study is to present average annual healthcare costs for Dutch renal replacement therapy (RRT) patients for 7 treatment modalities. METHODS: Health insurance claims data from 2012-2014 were used. All patients with a 2014 claim for dialysis or kidney transplantation were selected. The RRT related and RRT unrelated average annual healthcare costs were analysed for 5 dialysis modalities (in-centre haemodialysis (CHD), home haemodialysis (HHD), continuous ambulatory peritoneal dialysis (CAPD), automated peritoneal dialysis (APD) and multiple dialysis modalities in a year (Mix group)) and 2 transplant modalities (kidney from living and deceased donor, respectively)...
