Based on a negative infectious workup, empiric antibiotics were discontinued, and the patient was discharged home to await liver biopsy results to guide further management. [ijmyco.org]

(See Workup.) In general, MAC infection is treated with 2 or 3 antimicrobials for at least 12 months. Commonly used first-line drugs include macrolides (clarithromycin or azithromycin), ethambutol, and rifamycins (rifampin, rifabutin). [emedicine.medscape.com]

However, MAC disease is preventable. One of the best ways to prevent it is to avoid CD4 counts from dropping below 100 by starting potent HIV treatment. In people whose CD4 counts do not respond adequately, preventive drugs are taken. [poz.com]

Prevention It is not possible to avoid being exposed to the bacteria that cause MAC. The best way to prevent developing the disease is to keep your immune system strong and your CD4 count well above 50. [catie.ca]

CAN MAC BE PREVENTED? The bacteria that cause MAC are very common. It is not possible to avoid being exposed. The best way to prevent MAC is to take strong antiretroviral medications (ARVs). [aidsinfonet.org]
