AI Article Synopsis

  • - The study examined the survival benefits of automated peritoneal dialysis (APD) compared to continuous ambulatory peritoneal dialysis (CAPD), focusing on the effects of using icodextrin, with 148 patients categorized into four groups based on their treatment type over one year.
  • - Results indicated that the use of icodextrin in CAPD (CAPD+ET) had better patient survival rates than APD without icodextrin (APD-ET), although the differences were not statistically significant, particularly among non-diabetic patients.
  • - The findings suggest that APD without icodextrin may lead to poorer patient and technique survival due to challenges in volume control, particularly highlighted by a higher edema index

Article Abstract

Background: There is no conclusive evidence regarding the survival benefits of automated peritoneal dialysis (APD) or the use of icodextrin. This study aimed to evaluate patient and technique survival among four groups divided based on peritoneal dialysis modality and icodextrin use over 1 year.

Methods: We specifically included patients who underwent a single peritoneal dialysis modality for at least 1 year during that period (n = 148). The participants were categorized into four groups for comparison: continuous ambulatory peritoneal dialysis (CAPD) without icodextrin (CAPD-ET, n = 39); CAPD with icodextrin (CAPD+ET, n = 35); APD without icodextrin (APD-ET, n = 40); and APD with icodextrin (APD+ET, n = 34).

Results: The CAPD+ET group had a higher patient survival rate than that of the APD-ET group and also had a higher technique survival trend than that of the APD-ET group, despite no statistical significance. In patients without diabetes mellitus (DM), the APD-ET group had a poorer patient survival trend than those of the APD+ET or CAPD+ET groups. In patients without DM, the APD+ET group had a higher technique survival than the APD-ET group. In addition, the APD+ET group showed a higher technique survival trend than did the CAPD-ET group, despite non-statistical significance. The edema index after 1 year of follow-up was higher in the APD-ET group than in the other groups.

Conclusion: The present study demonstrated that patients undergoing APD without icodextrin had poor patient and technique survival trends, which may be caused by poor volume control.

Introduction: In chronic kidney disease (CKD) patients, elevated parathyroid hormone (PTH) is linked to cardiovascular mortality and morbidity. Levels of PTH are influenced by serum phosphate (P) and calcium (Ca), but little is known about the impact of magnesium (Mg) on PTH. Hence, this study investigated the relationship between PTH and Mg in peritoneal dialysis (PD) patients and non-dialysis patients from three hospitals in China.

Rationale & Objective: Peritoneal dialysis (PD) solutions provide both clearance of uremic toxins and sodium and water. An intraperitoneal (IP) solution of icodextrin and glucose designed without the requirement for uremic toxin clearance could provide substantially greater sodium and water removal than PD solutions.

Study Design: We examined varying concentrations of icodextrin and dextrose IP solutions in rats.

In silico drug repurposing at the cytoplasmic surface of human aquaporin 1.

Aquaporin 1 (AQP1) is a key channel for water transport in peritoneal dialysis. Inhibition of AQP1 could therefore impair water transport during peritoneal dialysis. It is not known whether inhibition of AQP1 occurs unintentionally due to off-target interactions of administered medications.

Paediatric Critical Care Research Group, Child Health Research Centre, The University of Queensland, South Brisbane, QLD, Australia.

Objectives: The objective of this study was to describe current use, clinical practice, and outcomes of continuous renal replacement therapy (CRRT) in children in the intensive care unit (ICU) in Australia and New Zealand.

Design: retrospective, binational registry-based cohort study and electronic survey of clinical practice.

Setting: ICUs that contribute to the Australian and New Zealand Paediatric Intensive Care Registry and a survey conducted in November 2021 including ICUs accredited for paediatric intensive care training that provide CRRT for children were part of this study.
