Evaluation of prevalence and predisposing factors for bronchiectasis in copd patients –across sectional study.

Abstract

ABSTRACT Introduction: Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory disorder marked by persistent airflow limitation and chronic inflammation. Bronchiectasis—characterized by irreversible bronchial dilatation—is increasingly recognized as a common comorbidity in COPD, forming the Bronchiectasis-COPD Overlap (BCO) phenotype. This overlap is associated with more severe symptoms, frequent exacerbations, greater bacterial colonization, and poorer outcomes. However, bronchiectasis remains underdiagnosed, especially in resource-limited settings like India, where routine HRCT is not always feasible. Identifying its prevalence and risk factors in COPD is essential for early diagnosis, appropriate management, and improved prognosis. Objectives: To determine the prevalence of bronchiectasis in COPD patients and identify associated predisposing risk factors.
