Peritoneal dialysis in children, what's different: Your questions answered.

Maintenance peritoneal dialysis (PD) is the most used kidney replacement therapy for children with kidney failure throughout the world. Underlying causes of kidney failure, indications for dialysis, body size, and nutritional requirements differ between children and adults on PD. These differences, along with the ongoing growth and development that occurs throughout childhood, impact PD access, prescription, and monitoring in children.

Assessment of potential peritonitis risk factors in pediatric patients receiving maintenance peritoneal dialysis.

Background: Many recommendations regarding peritonitis prevention in international consensus guidelines are opinion-based rather than evidence-based. The aim of this study was to examine the impact of peritoneal dialysis (PD) catheter insertion technique, timing of gastrostomy placement, and use of prophylactic antibiotics prior to dental, gastrointestinal, and genitourinary procedures on the risk of peritonitis in pediatric patients on PD.

Methods: We conducted a retrospective cohort study of pediatric patients on maintenance PD using data from the SCOPE collaborative from 2011 to 2022.

The cost of hospitalizations for treatment of hemodialysis catheter-associated blood stream infections in children: a retrospective cohort study.

Background: Hospitalization costs for treatment of hemodialysis (HD) catheter-associated blood stream infections (CA-BSI) in adults are high. No studies have evaluated hospitalization costs for HD CA-BSI in children or identified factors associated with high-cost hospitalizations.

Methods: We analyzed 160 HD CA-BSIs from the Standardizing Care to Improve Outcomes in Pediatric End-stage Kidney Disease (SCOPE) collaborative database linked to hospitalization encounters in the Pediatric Health Information System (PHIS) database.

A donor risk index for graft loss in pediatric living donor kidney transplantation.

Pediatric kidney transplant candidates often have multiple potential living donors (LDs); no evidence-based tool exists to compare potential LDs, or to decide between marginal LDs and deceased donor (DD) kidney transplantation (KT). We developed a pediatric living kidney donor profile index (P-LKDPI) on the same scale as the DD KDPI by using Cox regression to model the risk of all-cause graft loss as a function of living donor characteristics and DD KDPI. HLA-B mismatch (adjusted hazard ratio [aHR] per mismatch =  1.
