A disease caused by the fungus Histoplasma capsulatum. It primarily affects the lungs but can also occur as a disseminated disease that affects additional organs. The acute respiratory disease has symptoms similar to those of a cold or flu and it usually resolves without treatment in healthy individuals. The disseminated form is generally fatal if untreated.
Biomarker and diagnostic research for histoplasmosis has been reported in the published literature.
No approved treatments are currently available for histoplasmosis. An additional 1 compound holds orphan drug designation.
While no drugs are FDA-approved specifically for histoplasmosis, some of the following designated compounds may be used off-label in clinical practice. Treatment decisions should be made in consultation with a specialist familiar with this condition.
The following drugs have received orphan drug designation from the FDA for histoplasmosis. Orphan designation reflects regulatory interest and does not indicate approval for treatment.
