Laboratory and clinical assessment of ketoconazole in deep-seated mycoses.

Forty-eight cases of deep mycoses were studied and treated with ketoconazole, each with in vitro evaluation of the minimum inhibitory concentrations (MIC) of the causative fungi, in vivo pharmacokinetic, clinical, and mycologic evaluations, several months to two years after the treatment was stopped. Excellent results were obtained in six cases of chronic mucocutaneous candidiasis, with restoration of immunologic disturbances; 23 cases of systemic candidiasis, including new aspects of heroin addicts with cutaneous, ocular, or osteoarticular manifestations; eight cases of histoplasmosis, five due to Histoplasma capsulatum and three to Histoplasma duboisii, with cure in seven and remission in one; one case of African blastomycosis (Blastomyces dermatitidis); three cases of mycetoma, two due to Monosporium apiospermum, one due to a dematiacious fungus; three cases of entomophthoromycosis with cure; one case of fungal arthritis, due to new hyphomycete similar to M. apiospermum, pathogenic for laboratory animals; one case of Drechslera longirostrata causing vertebral arthritis, following a fungal endocarditis and cured by combination of ketoconazole with amphotericin B, each agent alone being ineffective; and other deep mycoses.
