ABSTRACT
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.
