简要总结
PRIMARY: To determine the efficacy of azithromycin and rifabutin alone and in combination for the prevention of disseminated Mycobacterium avium Complex (MAC) infection in HIV-infected patients. To determine the efficacy of daily versus weekly fluconazole for the prevention of deep fungal infections in this patient population.
SECONDARY: To determine the incidence of bacterial (including mycobacterial) infections, cryptosporidiosis, and toxoplasmosis in azithromycin versus non-azithromycin containing regimens. To determine the incidence of oropharyngeal and vaginal candidiasis in patients treated with daily versus weekly fluconazole. To compare survival and outcomes of primary endpoints in the treatment arms.
详细描述
Patients are randomized to receive azithromycin alone, rifabutin alone, or the two drugs in combination for MAC prophylaxis. Patients in each treatment group further receive one of two doses of concomitant fluconazole for deep fungal prophylaxis, unless specifically excluded for fluconazole randomization. Patients are followed for 1 to 2 years.
