Sphingomonas paucimobilis is an uncommon source of peritonitis in patients undergoing peritoneal dialysis (PD). Although only a small number of cases have been reported, treatment failure rate is extremely high, with removal of the peritoneal dialysis catheter noted in ~ 50% of reported cases. The potential damage to the peritoneal membrane from peritonitis with this organism and the ability to return to PD after infection is unknown. We report a unique case in which a patient was able to successfully return to PD after relapsing Sphingomonas paucimobilis peritonitis, without apparent effects to dialysis clearance or ultrafiltration. .
