Treatment of South American blastomycosis (paracoccidioidomycosis) with miconazole by the oral route: an on-going study.
Results are presented from 12 patients of both sexes, whose ages range from 34 to 65 years, observed over a period of 16 months and receiving miconazole treatment for South-American blastomycosis. Ten of them were being treated for the first time and the remaining 2 presented relapses after treatment with other chemotherapeutic agents. The blastomycotic lesions were localized in skin, mucosa, lung and lymphatics. The drug was administered orally, at a dosage of 1 g three times daily. One relapsing patient had his first daily oral dose replaced by an intravenous dose of 200 mg of miconazole diluted in 250 ml of glucose solution during the initial four weeks. The criterion for diagnosis was finding of the fungus in sputum and/or in the material collected through scrapings or biopsy of the lesions. All patients were treated in hospital until the cure was apparent, clinical examinations being conducted weekly and bi-weekly. Bi-weekly laboratory examinations were performed to evaluate the patient's tolerance to the drug. All treated patients presented complete healing of cutaneomucous lesions (mean time: 4 weeks) and involution of lymphatic and pulmonary features (mean time: 4 months). Two of them still presented palpable lymphatics after 5 months of treatment, in spite of the cure of mucosal and pulmonary lesions. Monitoring the progress of the cured patients was and is being carried out quarterly. Currently, this observation period ranges from three to 15 months. Nine patients are still returning and none have shown the reappearance of mycotic lesions. Diarrhoea was the only side-effect observed after a period of therapy, but it was easily controlled by specific medication (kaolin, pectin, &c.). In a single case the treatment was interrupted because of this symptom.(ABSTRACT TRUNCATED AT 250 WORDS)
