Insights
Peritoneal dialysis (PD) is common for children with end-stage renal disease. This study found PD-related peritonitis occurred every 23.7 months, with Staphylococcus aureus as a frequent cause.
Area of Science:
- Pediatric Nephrology
- Dialysis Therapy
- Infectious Diseases
Background:
- Chronic peritoneal dialysis (PD) is the primary renal replacement therapy for pediatric patients (<15 years) with end-stage renal disease.
- PD-related peritonitis is a significant complication impacting patient outcomes.
Purpose of the Study:
- To evaluate the incidence and characteristics of PD-related peritonitis in pediatric patients.
- To assess the effectiveness of common treatment regimens for PD peritonitis.
Main Methods:
- Retrospective chart review of 22 pediatric patients undergoing chronic PD.
- Analysis of peritonitis rates, causative organisms, and treatment outcomes.
Main Results:
- The overall peritonitis rate was 1 episode per 23.7 patient-months.
- No significant difference in peritonitis incidence between automated PD and continuous ambulatory PD (p=0.219).
- Staphylococcus aureus was the most common pathogen (13.3%).
Conclusions:
- Vancomycin plus ceftazidime is effective for common PD peritonitis pathogens.
- Consideration of rare organisms like fungi and mycobacteria is crucial for refractory cases.
- Early diagnosis and prompt treatment are vital to prevent mortality and long-term complications.
Abstract:
In most countries, chronic peritoneal dialysis (PD) is the preferred dialysis mode for children and adolescents below the age of 15 years with end-stage renal disease. PD-related peritonitis is a serious complication that has a great impact on uremic patients'outcome. We retrospectively reviewed the charts of a total of 22 uremic children who underwent chronic peritoneal dialysis. The total peritonitis rate in our study was one episode every 23.7 patient-months, and there was no significant difference in the incidence of peritonitis between children with automated peritoneal dialysis and those with continuous ambulatory peritoneal dialysis (p=0.219). Staphylococcus aureus was the most common causative organism, accounting for 13.3% of the episodes of peritonitis. The combination therapy of vancomycin plus ceftazidime is effective for common pathogens in peritonitis. Rare microorganisms, e. g., fungus and mycobacterium, should be taken into consideration when the response to initial treatment is poor. Early diagnosis and treatment is important to prevent sequelae and mortality.
