MAC lung disease symptoms vary and often are nonspecific, contributing to delay in diagnosis. Some people have mild or unnoticeable symptoms. Often symptoms aren’t even respiratory in nature. When symptoms occur, you may experience: Chronic cough with or without mucus. Hemoptysis or coughing up blood. Fatigue.

The MAC disease in AIDS is widely disseminated throughout the body and rarely involves the lung, while pulmonary MAC only involves the lungs. MAC pulmonary (lung) disease’ major susceptibility risk factors depend on which of the two types of disease are present. For nodular disease the risk factors are being Caucasian, female, average age ...
The incidence of nontuberculous mycobacterial (NTM) pulmonary disease caused by Mycobacterium avium complex (MAC) in apparently immune-competent people is increasing worldwide. We performed a systematic review of the published literature on five-year all-cause mortality in patients with MAC lung disease, and pooled the mortality rates to give an overall estimate of five-year mortality from ...
Key Facts. MAC infection is a serious condition that can cause damage to the lungs. MAC infection is not contagious. Common signs and symptoms of MAC lung disease include fatigue, chronic cough, shortness of breath, night sweats, coughing up blood and weight loss. Symptoms may persist or worsen despite being treated for another lung condition.
In patients without HIV, the course of MAC is somewhat mild with a life expectancy of 50% at 5 years. In patients with HIV, 5-year survival rates of 20 to 70% are reported- this depends on compliance with HAART therapy. ...

Table 3. Recommended Drug Substitutions for Mycobacterium avium Complex Lung Disease Therapy a. a. Suggestions from Tables 2 and 3 should be integrated to maximize efficacy and to prevent drug resistance. Open table in a new tab. Clofazimine is used widely for MAC LD, in spite of an uncertain impact on MAC treatment outcome. Two retrospective ...
Thus, the impact of MAC lung disease on mortality at a population level is more appropriately reflected in studies using matched control groups. As shown above, the three studies where MAC lung disease cases were matched with appropriate controls consistently showed an increased risk of mortality for patients with NTM-PD or MAC-PD [21, 26, 27].
Treatment of nontuberculous mycobacterial (NTM) infection of the lung is dependent upon a number of factors, including the species of the infecting organism. Members of Mycobacterium avium complex (MAC) are the most common pulmonary NTM pathogens in almost all regions of the world. The three predominant species to cause human disease among the ...
Among these, 18 patients died from MAC-PD-associated causes (progression of MAC-PD, n = 14; respiratory failure due to MAC-PD, n = 2; concomitant bacterial or fungal infection, n = 2) and nine patients died from other causes (interstitial pneumonia, n = 2; lung cancer, n = 2; chronic obstructive pulmonary disease, n = 1; heart failure n = 1 ...
