Predictive Value of Nutritional Status in Sputum Culture Conversion Among Patients with Nontuberculous Mycobacterial Pulmonary Disease: A Retrospective Cohort Study.

Discussion Current Status of Research on NTM-PD NTM-PD has shown an increasing trend globally and in China in recent years. 24 The pathogen spectrum is complex, primarily including Mycobacterium avium complex (MAC), M. intracellulare , M. abscessus , and M. kansasii , with geographic and environmental exposure differences. 25 Previous studies have mainly focused on pathogen identification, drug susceptibility, imaging features, and immunophenotypes, whereas the relationship between nutritional status (eg, BMI, serum protein/albumin levels) and sputum culture conversion or treatment outcomes has been less frequently reported.
