Summary

This study tests if a single high dose of an antifungal drug works better than the standard daily dose for treating moderate to severe histoplasmosis, a serious lung infection. It also compares a newer oral drug to the standard one, and checks if 6 months of treatment is as good as 12 months in people with HIV. About 664 hospitalized adults will take part to find safer, more effective ways to control this disease.
