A Case of Trichosporon beigelii Peritonitis in CAPD / 대한신장학회잡지

Fungal peritonitis is one of the leading causes of patient dropout from continuous ambulatory peritoneal dialysis (CAPD) therapy. Although the most causative agents of peritonitis associated with CAPD are bacteria, fungi are implicated in up to 10% of cases. The most common organism of fungal peritonitis is Candida specises, but Trichosporon beigelii was reported as a rare causative agent of fungal peritonitis. We experienced a case of CAPD peritonitis by Trichosporon beigelii, which was treated with CAPD catheter removal, and antifungal agents with amphotericin B and fluconazole. Thus, we report our experience of CAPD peritonitis caused by Trichosporon beigelii and review of the literature.

A Case of Chryseobacterium (Flavobacterium) meningosepticum Peritonitis in a Patient on CAPD / 대한신장학회잡지

Peritonitis remains the leading cause of morbidity and technique failure for patients undergoing continuous ambulatory peritoneal dialysis (CAPD). Chryseobacterium meningosepticum is the most common pathogen for humans among Chryseobacterium species and a few cases of CAPD peritonitis caused by C. meningosepticum were reported in the world. We experienced a case of CAPD peritonitis by C. meningosepticum in Ewha Womans University Hospital, Seoul, Korea. A 52-year-old diabetic woman on CAPD was admitted with turbid peritoneal fluid. She was suffered from three episodes of peritonitis. Effluent was cloudy with a cell count of 1,620 WBC/ mm3 (94% neutrophils, 4% lymphocytes). Effluent cultures obtained on 6th hospital day revealed a mixed growth of C. meningosepticum and P. aeruginosa. Tenckhoff catheter was removed due to persistent cloudy effluent till 9th hospital day. We herein report a case of peritonitis caused by C. meningosepticum and review the literature of similar cases of peritonitis.

A Case of Agrobacterium radiobacter Peritonitis in a Patient on CAPD / 대한신장학회잡지

Agrobacterium radiobacter is a rare human pathogen and a few cases were reported in the world. The peritoneal cavity in patient maintained on peritoneal dialysis serves as an excellent incubator and culture medium for microorganisms. We experienced a rare human infection as peritonitis with A. radiobacter in Inha University Hospital, Inchon, Korea. The patient was 36 year-old female and maintained on CAPD for one year. She had two times of CAPD peritonitis. She visited to the hospital because of turbid peritoneal fluid. On initial physical examination, she showed mild abdominal tenderness and elevated body temperature. Laboratory findings showed leukocytosis and anemia with elevated serum creatinine level. The analysis of peritoneal fluid showed white blood cell count as many as 1860/mm3 and it's culture revealed A. radiobacter. She received vancomycin and aminoglycoside antibiotics via intraperitoneal route and the CAPD catheter was removed. She was maintained on hemodialysis and reveived isepamicin 100mg a day via intravenous for 7 days. We report our experience of peritonitis caused by A. radiobacter and review the literature of similar cases of peritonitis.
