Relapsing peritonitis in children who undergo chronic peritoneal dialysis: a prospective study of the international pediatric peritonitis registry.

Background And Objectives: The International Pediatric Peritonitis Registry (IPPR) was established to collect prospective data regarding peritoneal dialysis (PD)-associated peritonitis in children. In this report, we present the IPPR results that pertain to relapsing peritonitis (RP).

Design, Setting, Participants, & Measurements: This was an online, prospective entry into the IPPR of data that pertain to peritonitis cases by participating centers.

Validation of estimates of total body water in pediatric dialysis patients by deuterium dilution.

Background: Current K-DOQI recommendations call for an assessment of dialysis adequacy that depends critically on an estimate of total body water (TBW). Such estimates are problematic in children since the range of patient size is large, and often formulas derived in normals are not validated in end-stage renal disease. Gold standard methods of TBW measurement, such as deuterium dilution ((2)H(2)O), are not appropriate in the clinical setting, yet noninvasive methods such as bioimpedance analysis (BIA) and dual energy x-ray absorptiometry (DEXA) have not been independently validated.
