[Therapy of candidiasis and cryptococcosis in AIDS].

Fungal infections figures large in HIV-infected patients. Candida infections of the mucous membranes belong to the main manifestations of immunodeficiency in HIV infection. For therapy and prophylaxis of oropharyngeal candidosis mainly systemically acting azoles as ketoconazole, fluconazole and itraconazole are applied; antimycotics to be administered topically regularly fail to act in patients with progressing disease. Ketoconazole tablets were used with good success in previous years of the AIDS epidemics. Application of ketoconazole in liquid formulation led to a significant increase in efficacy. Subsequently fluconazole proved to be a triazole with evidently better pharmacological properties leading to good clinical efficacy. Presently it represents the drug of first choice in acute and maintenance therapy of recurrent oropharyngeal and oesopharyngeal candidosis. In the case of therapy failure with fluconazole the administration of itraconazole in liquid cyclodextrine formulation can replace or at least delay the administration of amphotericin B plus flucytosine, a therapy rich in toxic side effects. The standard therapy of disseminated cryptococcosis--particularly of cerebral manifestation--is still the administration of amphotericin B combined with flucytosine. Alternative drugs are represented by fluconazole and itraconazole. However, an azole monotherapy seems to be legitimate only in primary cryptococcosis of the lungs or in early stages of secondary extrapulmonary infection. Cryptococcal meningitis requires an intense initial therapy. New therapy strategies were developed combining azoles with standard antimycotic drugs. The value of amphotericin B in liposomal or lipid complex formulations is still undetermined due to the up to now low number of AIDS patients treated.(ABSTRACT TRUNCATED AT 250 WORDS)
