The use of intraperitoneal (IP) vancomycin as initial, single agent therapy for gram positive and “no organism” continuous ambulatory peritoneal dialysis (CAPD) peritonitis is described, comparing continuous and intermittent adminstration schedules. “Continuous” therapy consisted of an IP 1-g loading dose of vancomycin followed by 30 mg/L dialysate effluent. “Intermittent” therapy consisted of 2 IP doses of 30 mg vancomycinlkg body weight-the initial dose delivered at diagnosis and the second dose 1 week later. All patients presenting with peritonitis (n = 90) were randomized to receive either continuous or intermittent vancomycin therapy. Patients in whom gram negative organisms and fungi were identified by microscopy and culture were transferred to therapy with a more appropriate antibiotic (n = 39). In the remainder (n = 51), CAPD peritonitis was treated solely with vancomycin (continuous, n = 21; intermittent, n = 30). Clinical resolution was seen in all patients, requiring a mean of 3.2 days for macroscopic clearing of dialysate effluent. Recurrence of peritonitis within 1 month of cessation of therapy was unusual and did not vary between treatment protocols (4121 v 3/30; P = NS). There were no differences in observed side effects. Thus, IP vancomycin proved to be a useful single agent therapy for gram positive and no organism CAPD peritonitis. Therapy with two IP doses was effective and as safe as continuous IP vancomycin therapy, and therefore should replace other vancomycin administration schedules in the treatment of CAPD peritonitis.
