LUNG ATS

Nodular bronchiectasis is a less severe form of NTM infection, in which the airways of the lungs dilate and become scarred. The airways lose their ability to clear mucus, providing an environment that encourages the growth of NTM... Cavitary disease is a more severe form of NTM-LD, in which scarring and progressive cavitation occur particularly in the upper lobes of the lungs. If left untreated, it may ultimately result in respiratory failure... The goal of curative therapy in NTM lung disease is at least 12 months of negative cultures following a multi-drug antibiotic regimen.
