Post-tuberculosis lung disease (PTLD) presents a significant challenge in the management of tuberculosis patients, with far-reaching implications for global health. This editorial explores the multifaceted nature of PTLD, encompassing its pathophysiology, clinical manifestations, diagnostic complexities, and implications for public health. PTLD arises from pulmonary damage due to an active tuberculosis infection, leading to inflammation, scarring, and fibrosis within the lungs. Clinical manifestations vary widely, ranging from chronic respiratory symptoms to severe respiratory failure, often resembling chronic obstructive pulmonary disease or restrictive lung disease. The diagnosis of PTLD is hindered by its heterogeneous presentation and overlap with other respiratory conditions, necessitating a comprehensive evaluation through pulmonary function tests and radiological imaging. PTLD imposes a substantial burden on global health systems, particularly in regions with high tuberculosis prevalence, contributing to increased morbidity and mortality rates. Management strategies focus on alleviating symptoms, preserving lung function, and preventing disease progression through pharmacological interventions, pulmonary rehabilitation, and, in select cases, surgical interventions. Preventive measures include effective tuberculosis control measures, vaccination against respiratory pathogens, and addressing social determinants of health. Overall, a comprehensive understanding of PTLD is essential for improving patient outcomes and reducing disease burden, highlighting the importance of concerted efforts to raise awareness, enhance diagnostic capabilities, and develop effective management strategies for this complex condition.
