Nontuberculous mycobacteria are ubiquitous and are usually found in soil, natural and treated water sources. They are relatively uncommon cause of pulmonary disease and likely to cause disseminated disease.
May cause both asymptomatic infection and symptomatic disease in humans.
There is no evidence of animal-to-human or human-to-human transmission in immunocompetent hosts.
Nontuberculous mycobacterial pulmonary disease is a generally slowly progressive infection.
Signs and symptoms are generally nonspecific.
A daily triple-drug regimen containing clarithromycin, rifampin and ethambutol for the treatment of nodular/bronchiectatic mycobacterium avium complex (MAC) lung disease produces a relatively high response rate similar to that seen in previous reports, as shown in a retrospective study from Japan.
Inhaled corticosteroids (ICS) were associated with an increased risk of nontuberculous mycobacteria pulmonary disease (NTM PD) in patients with asthma or chronic obstructive pulmonary disease (COPD) or both, compared with those who did not use ICS, according to a study presented at the recent American Thoracic Society (ATS) International Conference 2016 held in San Francisco, California, US.
