지속성 외래복막투석 환자에서 발생한 Chryseobacterium indologenes와 Sphingomonas paucimobilis 복합균주에 의한 복막염 1예

Abstract

Bacterial peritonitis is a well-recognized complication of continuous ambulatory peritoneal dialysis (CAPD) in patients with end-stage renal failure. Chryseobacterium indologenes is a non-fermentative Gram-negative bacillus that is a rare pathogen in humans and Sphinomomas paucimobilis has rarely been reported as an opportunistic human pathogen. We present a case of peritonitis due to unusual pathogens, C. indologenes and S. paucimobilis, unresponsive to the standard antibiotics therapy. A 51-year-old diabetic man undergoing CAPD for 45 days developed the first peritonitis due to C. indolegenes. Although he had received intraperitoneal antibiotics with good in vitro activity against organism, the signs of peritonitis persisted. S. paucimobilis was isolated from dialysate sample. The Tenckhoff catheter was finally removed on 19th day of hospitalization and the fever and abdominal pain subsided. Key Words : Chryseobacterium, Sphingomonas, Peritoneal dialysis, Peritonitis
