Intraperitoneal vancomycin/oral pefloxacin versus intraperitoneal vancomycin/gentamicin in the treatment of...

Sixty patients were enrolled in a prospective, randomized study to evaluate the efficacy of two different regimens for the empirical treatment of continuous ambulatory peritoneal dialysis (CAPD) peritonitis. At presentation, Group I received intraperitoneal vancomycin (1 g) and oral pefloxacin (400 mg b.i.d.), and Group II intraperitoneal vancomycin (1 g) and gentamicin (80 mg loading dose, followed by 15 mg/2 L). Treatment duration was 14 days. Despite randomization, Group I had significantly more patients with primary Candida peritonitis. When fungal peritonitis was excluded from analysis, there were no significant differences in the treatment success rate (Group I, 73.3% vs Group II, 80.0%, p = NS), number of relapses (Group I, 0 vs Group II, 1), and Tenckhoff catheter removal rates (Group I, 26.6% vs Group II, 16.6%, p = NS) between the two groups. The patients treated with pefloxacin had an increased incidence of nausea and vomiting. In selected situations oral pefloxacin may be a suitable substitute for intraperitoneal gentamicin as out-patient therapy for CAPD peritonitis.
