[Peritonitis in pediatric patients receiving peritoneal dialysis]

Area of Science:

• Pediatric Nephrology
• Infectious Diseases
• Dialysis Therapy

Background:

• Peritonitis is the most common complication of peritoneal dialysis (PD) in children, contributing significantly to morbidity and mortality.
• Investigating risk factors for peritonitis is crucial for improving outcomes in pediatric PD patients.

Purpose of the Study:

• To identify independent risk factors for peritonitis in pediatric patients undergoing peritoneal dialysis.
• To inform targeted primary prevention strategies for peritonitis in this population.

Main Methods:

• Retrospective collection of medical records from 85 pediatric patients treated with PD over ten years.
• Analysis of patient data to identify correlations between various factors and peritonitis incidence.

Main Results:

• The peritonitis rate was 0.75 episodes per patient-year, with Gram-positive organisms being more common.
• Significant independent risk factors identified: poor weight, non-automated PD, and short delay from catheter insertion to PD initiation.
• Early-onset peritonitis correlated with more frequent episodes; Gram-negative peritonitis linked to ureterostomy, and Gram-positive peritonitis to exit-site/tunnel infections.

Conclusions:

• A significant incidence of peritonitis necessitates targeted primary prevention strategies.
• Nutritional support is vital to address poor weight as a risk factor.
• Automated PD is recommended as the preferred modality to reduce peritonitis risk.
