Rhodotorula rubra peritonitis in patients undergoing continuous ambulatory peritoneal dialysis

Abstract

Although still uncommon, fungal peritonitis is being reported with increasing frequency in patients with renal failure who are undergoing long-term peritoneal dialysis. Although most cases have involved Candida albicans, other opportunistic pathogens have been reported as well. Recently, three patients were seen with serious peritoneal infections due to Rhodotorula rubra, a "nonpathogenic" fungus. In two patients, peritoneal fibrosis made further peritoneal dialysis impossible. The third patient died from complications of peritonitis. Environmental cultures revealed a possible common-source outbreak. Literature review reveals that infection due to this organism is most unusual and occurs only in the hospital setting in patients with serious compromise of host defenses.
