Paecilomyces varioti peritonitis in patients on continuous ambulatory peritoneal dialysis

Abstract

Paecilomyces varioti infection is a rare cause of peritonitis in patients on continuous ambulatory peritoneal dialysis (CAPD). We report two patients who developed P varioti peritonitis complicating CAPD. The clinical features and microbiological data of seven other previously reported cases are reviewed. Approximately half of the patients had received multiple antibiotics before the onset of the peritonitis because of either bacterial peritonitis or exit site infection. There was no particular pattern of peritoneal dialysate cell count, which was characteristic in this fungal peritonitis. Although all patients survived, morbidity was high. All patients required antifungal chemotherapy and removal of peritoneal catheter for eradication of the organism. Amphotericin B was effective in most cases. Patients of all previously reported cases did not go back to peritoneal dialysis after removal of peritoneal catheters. A combination of oral flucytosine and itraconazole was successful in treating our two patients. Although we managed to resume CAPD in our two patients with good functional outcome, abscesses and adhesions were major problems rendering most patients from other series failing to return to CAPD after recovery.
