Peritonitis in peritoneal dialysis.

Area of Science:

• Nephrology
• Infectious Diseases
• Medical Technology

Background:

• Peritonitis is a significant complication of peritoneal dialysis (PD), contributing to patient morbidity.
• Understanding pathogen distribution is crucial, as Gram-negative infections correlate with higher rates of catheter loss and mortality.
• Intraluminal and periluminal contamination are the primary routes for PD-related infections.

Purpose of the Study:

• To review the clinical presentation, diagnosis, and differential diagnosis of peritonitis in PD patients.
• To discuss the impact of pathogen distribution on patient outcomes.
• To examine trends in peritonitis incidence, treatment recommendations, and future research directions.

Main Methods:

• Literature review of clinical presentations and diagnostic criteria for PD peritonitis.
• Analysis of pathogen distribution and its association with outcomes.
• Examination of historical trends in prevention strategies and treatment guidelines.

Main Results:

• The incidence of PD peritonitis has decreased over the past two decades due to implemented prevention methods.
• Clinical presentation and laboratory data are key for diagnosing peritonitis.
• Gram-negative infections are linked to poorer outcomes, including catheter loss and increased mortality.

Conclusions:

• While prevention strategies have improved PD peritonitis rates, ongoing research is essential.
• Future research should focus on enteric peritonitis, biocompatible dialysis solutions, and catheter materials.
• Optimizing treatment and prevention remains critical for improving PD patient outcomes.
