title: The use of ketoconazole in the treatment of blastomycosis.
abstract: We retrospectively reviewed our experience using ketoconazole in the therapy of blastomycosis. Over the course of 30 months, blastomycosis was diagnosed in 11 patients. Their clinical presentations ranged from the asymptomatic pulmonary nodule to the adult respiratory distress syndrome. Six of 8 patients treated with ketoconazole completed a 6-month course of 400 mg daily. Seventeen to 40 months after completion of therapy, the patients who had completed 6 months of therapy were well. Ketoconazole should play a major role in the therapy of blastomycosis because of its efficacy and because its administrative costs are lower than those of amphotericin B. It can be recommended for patients who have been symptomatic for longer than 3 wk and are not improving and for those who undergo resection of an asymptomatic pulmonary nodule. Amphotericin B remains the drug of choice in patients with life-threatening illness who require ventilatory assistance, have developed renal failure, or have central nervous system involvement. Severely immunocompromised patients with disseminated disease should also be treated with amphotericin B. Patients treated with ketoconazole should have close medical follow-up.
