Peritonitis Due To Candida Sp
Peritonitis due to Candida sp. may develop in patients with peritoneal dialysis catheters, or in those with surgical or traumatic injury to the gut wall. In this latter situation, Candida spp. are usually part of a polymicrobial infection. Isolation of Candida by direct examination of peritoneal fluid is an independent factor for a severe outcome, and recent small studies suggest that prompt, effective, adequate and safe antifungal therapy should be given in all cases of Candida sp. peritonitis in order to lower the mortality rate and shorten the hospital stay., In a recent study of 23 cases secondary to peptic ulcer perforation, the mortality rate in patients receiving fluconazole was high , probably related to inadequate or too late initiation of antifungal therapy. Some cases showing fluconazole efficacy have been reported in patients with continuous ambulatory peritoneal dialysis, either alone or in combination with flucytosine. Catheter removal is crucial in these cases.
