MAC lung disease is manifested either by fibrocavitary radiographic changes similar to pulmonary tuberculosis or by bronchiectasis with nodular and reticulonodular radiographic changes. With adherence to guideline-based therapy, treatment is successful in two thirds of treatment-naïve patients without macrolide resistance. Guidelines-based MAC therapy with multidrug regimens including macrolides is usually effective, but far from as predictably effective and durable as therapy for tuberculosis. Good RC.

Mycobacterium avium complex (MAC) causes disseminated disease in up to 40% of patients with advanced human immunodeficiency virus (HIV) disease in the United States. The selection of patients for treatment, the composition of treatment regimens, the optimal dosing schedules for drugs, the overall duration of treatment, and the most meaningful endpoints of therapy all are controversial and poorly defined (6). Although MAC infection is usually subclinical and self-limited in healthy individuals, it is a common gastrointestinal bacterial infection in AIDS patients whose CD4 counts are <50–100/mm 3 and in patients who receive immunosuppressive treatment… Treatment for mycobacterium avium complex usually involves a combination of anti-tuberculosis antibiotics, including: Ciprofloxacin, Rifabutin, Ethambutol, Clarithromycin, Rifampicin, Azithromycin, Amikacin, and Streptomycin…  |  Keywords: Definition.

It is imperative that clinicians are familiar with MAC drug resistance mechanisms and the pitfalls of inappropriate dependence on in vitro drug susceptibility testing which can predispose patients to the development of macrolide resistance with its attendant high mortality. Treatment of nontuberculous mycobacterial (NTM) infection of the lung is dependent upon a number of factors, including the species of the infecting organism. Mycobacterium avium complex (MAC) is the major pathologic nontuberculous mycobacteria causing lung disease (LD) in humans worldwide. Although the discovery of new treatment options is warranted, adherence to guidelines remains most crucial in treating patients with MAC-LD.
