US experience with itraconazole in Aspergillus, Cryptococcus and Histoplasma infections in the immunocompromised host.
Itraconazole has emerged as an important new oral agent in the treatment of systemic fungal infections. This paper summarizes the data available on its use in aspergillosis, cryptococcosis and histoplasmosis, compiled in the United States with particular attention to the immunocompromised host. Data have been accrued in open-label studies including 57 patients with cryptococcal disease where the overall response rate among patients with meningitis was 86%, and in 28 patients (8 with acquired immune deficiency syndrome (AIDS) or human immunodeficiency virus (HIV) infection) with invasive aspergillosis where the overall response rates were 80% in patients without AIDS and 86% in patients with AIDS. Data are summarized on 6 patients with allergic bronchopulmonary aspergillosis, 5 of whom demonstrated marked improvement on therapy, and 12 patients with histoplasmosis including 8 with AIDS, 11 of whom responded and 1 recrudesced on therapy. In summary, itraconazole showed activity in human studies of aspergillosis, cryptococcosis and histoplasmosis with minimal toxicity. Itraconazole offers a new oral alternative to conventional amphotericin B therapy in these infections. Comparative studies are needed to clarify its role.
