Diagram of the conditions that likely predisposed our subject to NTM lung infection. The texts within the maroon-colored background are the conditions, with the purported mechanisms located “downstream” in the direction of the arrows. The double-ended arrow connecting “NTM lung disease” and “low body weight” is used to denote that low body weight predisposes to NTM lung disease and vice versa. AAT, alpha-1-antitrypsin; FSH, follicle stimulating hormone; GER, gastroesophageal reflux; LH, luteinizing hormone; NTM, non-tuberculous mycobacteria; PiMS, protease inhibitor phenotype “MS”; PPI, proton pump inhibitor.
