A review of more than 50 allergic fungal sinusitis (AFS) patients indicates that most patients experience postoperative recurrences once weaned from oral steroids, leaving a glaring need for improved treatment. Topical antifungal therapy has not been described for AFS, but it could potentially lower fungal antigen loads via postoperative irrigations. No information exists to direct the choice of antifungal agent. The purpose of this study was to identify the appropriate drug to use for postoperative irrigations in AFS patients. Twenty-two fungal cultures grown from 15 AFS patients were studied for in vitro susceptibility to five common antifungal drugs: ketoconazole, amphotericin B, itraconazole, nystatin, and fluconazole. Results demonstrated that ketoconazole and amphotericin B were the most effective. Clinical trials are indicated to evaluate the efficacy of these drugs as a supplement to current Ales treatment.
