Abstract
A randomized trial was conducted comparing ketoconazole and nystatin in the prevention of oral candidiasis and appearance of invasive fungal infections in 51 neutropenic leukemic patients undergoing induction chemotherapy. Ketoconazole was administered in a 200 mg dose twice daily. Nystatin oral suspension was given in doses of 500,000 units four times daily. Surveillance cultures of the throat and urine were obtained prior to treatment and conducted weekly. Patients were enrolled in the study if the absolute granulocyte count was less than 1500/microliter, if physical examination revealed no evidence of oral candidiasis, no evidence of urinary tract infection, and there was no pulmonary infiltrate on chest x-ray. Patients were continued on study until the absolute granulocyte count reached 1500/microliter, evidence of oral candidiasis appeared, or presumed or proven invasive fungal infections appeared. Of the 46 evaluable patients, 22 received ketoconazole, 3 (14%) developed oral candidiasis, and 5 developed suspected systemic fungal infections (23%). Of 24 patients who received nystatin, 4 (17%) developed oral candidiasis and 8 (33%) developed systemic fungal infections, 4 proven and 4 suspected. Significantly more patients on the nystatin arm progressed to invasive fungal infections. Ketoconazole was not superior to nystatin in reducing the frequency of oral candidiasis but possibly reduced the frequency of invasive fungal infections.
