title: The effects of weekly mupirocin application on infections in continuous ambulatory peritoneal dialysis patients.
abstract: Application of mupirocin to the nares or catheter exit site and frequency of mupirocin administration in continuous ambulatory peritoneal dialysis (CAPD) patients remain controversial. The objective of our study was to evaluate, using a historical control group, the efficacy on CAPD-related infections of once-weekly application of mupirocin at the catheter exit site. We instructed 18 CAPD patients, who did not initially use prophylactic antibiotic treatment, about once-weekly application of mupirocin ointment to the exit site as part of their exit-site care. We recorded the incidence of catheter-related infections, the causative micro-organisms, and the rate of catheter loss. We observed 17 acute exit-site infections (AESIs: 0.45 episodes/patient-year) before mupirocin treatment and 2 AESIs (0.06 episodes/patient-year) after treatment. The relative rate of AESI reduction was 86%. Before application of mupirocin, 52% of AESIs were attributable to Staphylococcus-aureus; after mupirocin administration, no AESIs were staphylococcal. Peritonitis episodes were also reduced from 21 before mupirocin treatment (0.56 episodes/patient-year), to 9 after mupirocin administration (0.29 episodes/patient-year). The relative rate of peritonitis reduction was 48%. Once-weekly application of mupirocin to the exit site resulted in a reduction in exit-site infections and peritonitis episodes comparable to those obtained with daily application.
