Study on the Correlation Between Metabolomics and Anxiety and Depression in Bronchiectasis

Bronchiectasis is a common lung disease. Approximately 20-40% of patients with bronchiectasis experience comorbid anxiety and depression. Multiple studies have now demonstrated that anxiety and depression are associated with an increased risk of disease exacerbation in these individuals. Therefore, this study aims to collect data on anxiety and depression status, disease exacerbation frequency, hospitalisation rates, and mortality among participants diagnosed with bronchiectasis. Concurrently, biological samples including blood, sputum, and stool will be obtained. Through metabolomics analysis, we will investigate the expression of anxiety and depression-related metabolic pathways and identify corresponding biomarkers to explore their role in the progression of bronchiectasis.
