This clinical trial is focused on studying Chronic Obstructive Pulmonary Disease (COPD), a lung condition that makes it hard to breathe. The study will use a treatment called Budesonide, which is an inhalation powder. Budesonide is a type of medication known as a glucocorticosteroid, which helps reduce inflammation in the lungs.
The purpose of the study is to understand the molecular changes that occur in patients with COPD when treated with Budesonide, especially in relation to their blood eosinophil levels. Eosinophils are a type of white blood cell that can be involved in inflammation. The study will compare these changes in patients who receive Budesonide with those who do not, over a period of eight weeks.
Participants in the study will be monitored for changes in their body at a molecular level, such as in their microbiome, which is the collection of all the microorganisms living in the body, and their transcriptome, which involves the study of RNA molecules. These changes will be observed through samples taken from sputum, nasal and throat swabs, urine, and blood. The study aims to provide insights into how Budesonide affects patients with different severities of COPD and varying levels of eosinophils in their blood.
