Peritoneal dialysis-related peritonitis caused by Rhodococcus corynebacterioides

AbstractA 57-year-old Japanese man on peritoneal dialysis developed peritoneal dialysis-associated peritonitis caused byRhodococcus corynebacterioides. After the introduction of peritoneal dialysis, he had experienced four episodes of peritonitis, but the causative organism was not identified in any of episode. When he was hospitalized for the fifth episode of peritonitis,Rhodococcus corynebacterioides was detected in the ascitic fluid. He improved after an intraperitoneal administration of vancomycin (VCM) that was used based on the treatment of peritonitis caused byCorynebacterium spp. However, he then had repeated flare-ups and eventually required the removal of the peritoneal dialysis catheter due to recurrent peritonitis. 16S rRNA gene sequencing is generally needed to positively identifyRhodococcus corynebacterioides. In this case, we were able to rapidly identify the organism by using mass spectrometry and then apply this knowledge to the patient's treatment. To the best of our knowledge, this is the first reported case of peritoneal dialysis-associated peritonitis caused byRhodococcus corynebacterioides.
