Peritonitis due to Trichosporon asahii in a continuous ambulatory peritoneal dialysis patient

Fungal peritonitis is an important cause of intractable peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients. Candida species are the most common cause of fungal peritonitis, while Trichosporon asahii is rarely reported. Here, we report a case of peritonitis due to T. asahii in a 44-year-old woman who had undergone CAPD for 8 years. She was admitted to our hospital with diarrhea and fever. The clinical findings and analysis of the peritoneal fluid were consistent with peritonitis, and a culture of the peritoneal fluid revealed T. asahii. The peritonitis was treated by removing the peritoneal catheter and administering amphotericin B and fluconazole. T. asahii peritonitis is rare, but it should be considered as one of the important organism in fungal peritonitis in a CAPD patient. (Korean J Med 75:714-717, 2008)
