The exacerbating effects of stable pulmonary tuberculosis on the deterioration of inflammatory response, coagulation function, and pulmonary function in COPD: A propensity score-matched retrospective study.

Chronic obstructive pulmonary disease (COPD) and tuberculosis pose significant public health challenges, particularly in tuberculosis-endemic developing regions where their co-prevalence may exacerbate the disease burden of chronic airflow obstruction. This study aimed to investigate the impact of stable pulmonary tuberculosis on inflammatory status, coagulation function, and pulmonary function in COPD patients during acute exacerbations.We conducted a retrospective analysis of 68 COPD patients with acute exacerbation and stable pulmonary tuberculosis (observation group) admitted between December 2019 and December 2023.
