Peritonitis caused by paracoccidioides spp. in a patient on continuous ambulatory peritoneal dialysis - A case report

Paracoccidioidomycosis is a systemic mycosis found mainly in South America and is the most prevalent endemic and systemic mycosis in Brazil. The purpose of this paper was to report the case of a male patient who developed peritonitis caused by Paracoccidioides spp. Forty-eight-year-old, male patient, with type I Diabetes mellitus and chronic kidney disease who was undergoing a Continuous Ambulatory Peritoneal Dialysis (CAPD) program. After eighteen months of peritoneal dialysis, the patient developed turbidity of the peritoneal fluid and was diagnosed with peritonitis. Direct mycological examination of the peritoneal fluid revealed yeasts with morphology suggestive of Paracoccidioides spp. The patient was treated with sulfamethoxazole-trimethoprim (1,600 mg/320 mg dose/day) for 61 days, but he died because a bacterial septic shock. The diagnosis of opportunistic PCM peritonitis was later confirmed by autopsy and Paracoccidioides spp. isolation. This is the first reported case of a patient on CAPD who experienced complications due peritonitis caused by opportunistic PCM.
