Summary Objective To describe the clinical and microbiological features associated with fungal peritonitis in peritoneal dialysis (PD) patients at Hopital Maisonneuve-Rosemont, from August 1996 to July 2006. Methods Cases were retrieved from the microbiology laboratory culture registry. Antifungal susceptibility was determined by the Clinical and Laboratory Standards Institute M27A3 method. Results Among 288 PD patients (total follow-up of 7258 patient-months), nine were found with fungal peritonitis. Candida spp were identified in all of them, with a majority of non-albicans Candida species. Resistance to fluconazole, itraconazole, or voriconazole was as frequent as potential resistance to amphotericin B. No isolate was resistant to caspofungin and one was resistant to micafungin. Prior bacterial peritonitis was frequent (67%). All patients had their PD catheter removed and all of them survived. Conclusions In our institution, fungal peritonitis in PD patients is rare. All cases were caused by Candida species. Variable susceptibility patterns were observed, which may influence the initial empirical antifungal therapy and underscore the importance of individual speciation and susceptibility testing of invasive Candida isolates.
