BACKGROUND: The spectrum of bacterial peritonitis in patients on continuous ambulatory peritoneal dialysis (CAPD) in India may be different from that seen in developed countries because of differences in culture and in social, environmental, financial, and educational status. We analyzed our data regarding the incidence and outcome of monomicrobial peritonitis in our CAPD patients. PATIENTS AND METHODS: We reviewed the records of 225 patients on CAPD to retrieve data concerning demographics, peritonitis rate, organism isolated, and outcome. Polymicrobial and fungal peritonitis were excluded from the outcome analysis because of their different outcomes. RESULTS: We identified 168 episodes of peritonitis (range: 1 - 6 episodes per patient). Of the 168 episodes, 106 (63.1%) episodes were culture-positive. Total duration of CAPD was 264.16 patient-years. The overall peritonitis rate was 0.63 episodes per patient-CAPD year. The rates of gram-negative, gram-positive, polymicrobial, and fungal peritonitis were 0.17, 0.11, 0.04, 0.09 episodes per patient-year, respectively. Among the 75 episodes of monomicrobial peritonitis, gram-negative episodes [n = 45 (60%)] were significantly more frequent than gram-positive episodes [n = 30 (40%), p = 0.03]. Escherichia coli was the most commonly seen organism. Organisms of fecal origin (40/75) were significantly more frequent than those of skin origin (21/75, p = 0.0016). Catheter loss (17/45 vs 5/20, p = 0.04), hospitalization (31/45 vs 13/30, p = 0.03), death [9/45 vs 3/30, p = nonsignificant (NS)], switch to hemodialysis (8.9% vs 3.3%, p = NS), and reimplantation of the catheter (6.6% vs 3.3%, p = NS) were all more frequent in gram-negative episodes than in gram-positive episodes. CONCLUSIONS: Gram-negative peritonitis is more frequent than gram-positive peritonitis in our CAPD population in India and is associated with worse outcome.
