A rare cause of peritoneal dialysis-related peritonitis: Gemella haemolysans.

摘要

Gemellahaemolysanss a facultative, anaerobic, gram-positive coccus that is a commensal micro-organism of the mucous membranes of humans (1). We report the first case of continuous ambulatory peritoneal dialysis (CAPD)-related peritonitis due to Gemelta haemotysans. A 61-year-old man who had been receiving CAPD therapy for approximately 1.5 years because of end-stage renal disease due to diabetes mellitus presented with a classic clinic of peritonitis. No finding of inflammation was observed on either the exit site or the tunnel of the CAPD catheter. White blood cell count (WBC) in perito-nealeffluentwasl400/mm3, with neutrophils predominating. Gram stain of the peritonealfluid showed a small amount gram-positive cocci. The patient was started on antibiotic treatment with cephazolin 2 g per day intra-peritoneally. The peritoneal effluent cultures grew Gemella haemolysans. Hemoculture did not grow any micro-organism. He healed rapidly and his dialysate WBC decreased to 50/mm3. Cephazolin 2 g per day intraperi-toneally was continued for 21 days. The Tenckhoff catheter was not removed. During the 2 months following the therapy, peritonitis did not recur.
