Conditions associated with relapse of amphotericin B-treated disseminated histoplasmosis.
Progressive disseminated histoplasmosis (PDH) is a rare consequence of infection with Histoplasmia capsulatum. Usually fatal if untreated, PDH generally is cured by appropriate amphotericin B treatment. Of 31 persons with uncomplicated PDH treated with amphotericin B, we found that relapse occurred in five (16%) after an interval of up to nine years after initial therapy. Review of these five cases and 31 additional relapsing cases from the literature indicates that fungal endocarditis or endarteritis without surgical treatment, underlying lymphoreticular neoplasm, and amphotericin B dosage of less than 2 g appear to be associated with relapse of PDH.
