Candida parapsilosis peritonitis in patients on CAPD

Twenty-four episodes of C. parapsilosis peritonitis in 23 patients on continuous ambulatory peritoneal dialysis (CAPD) over 6 years were reviewed. Clinical manifestations and laboratory findings were similar to those of other pathogens. All started treatment with intravenous amphotericin B. In six cases it was attempted to maintain a peritoneal catheter in situ, but removal became essential to relieve fungal peritonitis. Of the patients who developed peritonitis, 15 episodes (62.5%) continued the CAPD program. Nine cases could not resume CAPD because of death in 4, patient preference in 2, and abdominal adhesion in 3. Antifungal treatment alone was ineffective in most cases. It was found that peritonitis developing after gram negative bacterial peritonitis and the use of fluconazole after catheter removal were associated with CAPD discontinuation. It was suggested that C. parapsilosis peritonitis in CAPD patients should be treated with rapid catheter removal, particularly those with fungal peritonitis who had prior gram negative peritonitis.
