Summary
Peritonitis remains a significant challenge in peritoneal dialysis. A new empirical treatment protocol, incorporating vancomycin, gentamicin, and ciprofloxacin, demonstrated a 96% coverage rate, significantly improving upon existing methods.
Area of Science:
- Nephrology
- Infectious Diseases
- Clinical Microbiology
Background:
- Peritonitis is a major complication in peritoneal dialysis (PD).
- Causative organisms and their antibiotic sensitivities vary, necessitating continuous epidemiological surveillance.
- Current empirical treatment protocols may not offer optimal coverage.
Purpose of the Study:
- To evaluate the impact of bacterial characteristics on empirical peritonitis treatment effectiveness in PD.
- To propose a novel, more effective empirical treatment protocol for PD-related peritonitis.
Main Methods:
- Retrospective analysis of 50 peritonitis episodes from a university hospital PD program (1994-1996).
- Evaluation of microbiological cultures, dialysate microscopy, and clinical outcomes.
- Comparison of a new proposed protocol with the Ad Hoc Advisory Committee protocol.
Main Results:
- Gram-positive bacteria were identified in 34 episodes, and Gram-negative in 16.
- Staphylococci showed 33% resistance to methicillin; no vancomycin resistance was observed.
- The proposed protocol achieved 96% coverage, significantly higher than the 78% of the Ad Hoc protocol (p < 0.01).
Conclusions:
- Empirical treatment protocols for PD peritonitis should be tailored to local epidemiological data.
- A new protocol using vancomycin, gentamicin, and ciprofloxacin offers superior coverage.
- Ongoing monitoring of causative organisms and sensitivities is crucial for adapting treatment guidelines.
