A Randomized, Double-Blind, Comparative Study of Azithromycin Versus Clarithromycin in Combination With Ethambutol for the Treatment of Disseminated Mycobacterium Avium Complex (MAC) Infection in AIDs Patients
To evaluate the efficacy and safety of two different doses of azithromycin in combination with ethambutol for the treatment of patients with Mycobacterium avium complex (MAC) infection, and to determine whether an azithromycin-containing regimen is at least as safe and effective as the same regimen containing clarithromycin..
Patients are randomized to receive azithromycin at one of two doses in combination with ethambutol or clarithromycin in combination with ethambutol for 24 weeks, after which they are evaluated for entry into a maintenance phase of treatment. Clinical, microbiologic, and safety assessments are performed every 3 weeks for the first 12 weeks, then monthly for the remaining 12 weeks.

Mycobacterium Avium-intracellulare Infection
A nontuberculous infection when occurring in humans. It is characterized by pulmonary disease, lymphadenitis in children, and systemic disease in AIDS patients. Mycobacterium avium-intracellulare infection of birds and swine results in tuberculosis.
A semi-synthetic macrolide antibiotic structurally related to ERYTHROMYCIN. It has been used in the treatment of Mycobacterium avium intracellulare infections, toxoplasmosis, and cryptosporidiosis.
Mycobacterium Avium Complex
A complex that includes several strains of M. avium. M. intracellulare is not easily distinguished from M. avium and therefore is included in the complex. These organisms are most frequently found in pulmonary secretions from persons with a tuberculous-like mycobacteriosis. Strains of this complex have also been associated with childhood lymphadenitis and AIDS; M. avium alone causes tuberculosis in a variety of birds and other animals, including pigs.
So-called atypical species of the genus MYCOBACTERIUM. They are also called tuberculoid bacilli, i.e.: M. buruli, M. chelonae, M. duvalii, M. flavescens, M. fortuitum, M. gilvum, M. gordonae, M. intracellulare (see MYCOBACTERIUM AVIUM COMPLEX;), M. kansasii, M. marinum, M. obuense, M. scrofulaceum, M. szulgai, M. terrae, M. ulcerans, M. xenopi.
