Nontuberculous Mycobacterial Lung Diseases

Area of Science:

• Respiratory Medicine
• Infectious Diseases
• Microbiology

Background:

• Nontuberculous mycobacteria (NTM) are emerging as significant pulmonary pathogens.
• Global incidence and prevalence of NTM lung disease are rising, particularly in aging and immunocompromised populations.
• Diagnosis and treatment are challenging due to varied symptoms and complex identification.

Purpose of the Study:

• To review the epidemiology, pathogenesis, clinical features, diagnostic approach, and management of NTM lung diseases.

Main Methods:

• A narrative review of literature from PubMed, Scopus, and Google Scholar.
• Included original research, clinical guidelines, and reviews on pulmonary NTM infections.
• Synthesized qualitative data focusing on clinical and diagnostic aspects.

Main Results:

• Common causative agents include Mycobacterium avium complex and Mycobacterium kansasii.
• Often affects individuals with underlying lung conditions (e.g., bronchiectasis, COPD) or compromised immunity.
• Diagnosis requires integrated clinical, radiological, and microbiological findings; management involves prolonged, complex multidrug regimens.

Conclusions:

• NTM lung disease is a growing respiratory challenge requiring early recognition and accurate diagnosis.
• Individualized treatment strategies are essential for improving patient outcomes.
• Further research and standardized guidelines are needed to optimize care.
