AIDS: Histoplasmosis is an important cause of morbidity and death in HIV-infected patients. Significant developments concerning the diagnosis, treatment, follow-up, and prophylaxis of histoplasmosis are discussed. Itraconazole is highly effective at both inducing and maintaining remission in mild to moderate cases of disseminated histoplasmosis. In cases of moderate to severe disease, amphotericin B remains the therapy of choice. A table presents comparative results of treating mild to moderate disseminated histoplasmosis with the drugs itraconazole versus fluconazole. Currently, no resistance of Histoplasmosis capsulatum to itraconazole has emerged from prolonged therapy. Maintenance therapy for life is recommended for patients with CD4 counts less than 100; however, feasibility studies are evaluating the possibility of its discontinuance. While no prophylaxis recommendations currently exist, patients with CD4 counts less than 100 who are exposed to histoplasmosis are recommended to begin oral itraconazole (200 mg daily).
