Patients with nontuberculous mycobacterial lung disease (NTM-LD) often have significant exercise intolerance and poorer health-related quality of life (HRQL). The goals of treatment for NTM-LD should include reducing the severity of symptoms, improving HRQL, and reducing acute exacerbations. Nonpharmacological treatment, including pulmonary rehabilitation program and optimal nutritional strategy, should be one part of treatment for NTM-LD. ⋯ An adequate protein and caloric diet combined with antioxidant nutrients might be the most appropriate dietary strategy. Comprehensive treatment for NTM-LD should include the combination of both pharmacological and nonpharmacological treatments. The management programs should be tailored to the individual's condition.

Mycobacterium avium complex (MAC) is the major pathologic nontuberculous mycobacteria causing lung disease (LD) in humans worldwide. Although the burden of MAC-LD has increased over the past two decades, treatment remains difficult because of intolerance of long-term antibiotics, lack of adherence to guidelines, and disease recurrence. The current guidelines recommend antibiotic initiation for patients with MAC-LD and severe disease and in those with disease progression. ⋯ Without adherence, macrolide resistance can occur, which leads to poor outcomes in patients with MAC-LD. Although the discovery of new treatment options is warranted, adherence to guidelines remains most crucial in treating patients with MAC-LD. It is worth mentioning that the majority of current recommendations are based on observational studies or small-scale clinical trials.

Nontuberculous mycobacteria (NTM) are critical emerging global infectious pathogens. Though NTM can be mere colonizers when isolated from human specimens, NTM are also responsible for diverse human infections. NTM-lung disease (NTM-LD) is the most common human disease entity. ⋯ Third, researchers in Taiwan have published valuable research investigating NTM among special patient populations, including patients in intensive care units, with ventilator dependency, with pulmonary tuberculosis, and who are infected with specific NTM species. The largest obstacle to clarifying NTM epidemiology in Taiwan may be the lack of routine NTM species identification in laboratories. Increased awareness of NTM diseases and acknowledgment that NTM species identification is crucial and guides clinical management are essential steps for facilitating the identification of NTM species in laboratories.
