U.S., July 30 -- ClinicalTrials.gov registry received information related to the study (NCT07733635) titled 'Vitamin D Status and Asthma Control, Pulmonary Function, and Oxidative Stress in Adults With Bronchial Asthma' on July 22.
Brief Summary: Asthma is a chronic inflammatory airway disease associated with variable airflow limitation and persistent respiratory symptoms. Vitamin D has been proposed as a potential biomarker related to immune regulation, asthma control, pulmonary function, and oxidative stress balance.
This prospective cross-sectional observational study aims to investigate the association between serum 25-hydroxyvitamin D [25(OH)D] concentrations, asthma control, pulmonary function parameters, and erythrocyte oxidative s...
