After 12 months of treatment, 42 (74%) patients had a favorable response to treatment, whereas 15 (26%) patients had an unfavorable response to treatment defined as the absence of sputum culture conversion within 12 months of treatment. [ncbi.nlm.nih.gov]
Prognosis
CONCLUSIONS: The radiological score correlates with prognosis. The combined score of factors I, C and E may more accurately predict prognosis in MAC-LD patients. [ncbi.nlm.nih.gov]
Little is known regarding the prognosis of untreated stable MAC-LD. [erj.ersjournals.com]
Etiology
An acute inflammatory nodule of unknown etiology can pose a formidable diagnostic challenge. [ncbi.nlm.nih.gov]

Prevention
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 General : Preventative therapy is usually recommended for AIDS patients who have a CD4 cell count lower than 50 cells per microliter of blood. [livingnaturally.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]
