NCT00661973
The main objective is to evaluate how treatment with inhaled corticosteroids (ICS) affects the characteristics of airway smooth muscle (ASM) cells from asthmatic subjects. Our hypothesis is that airway smooth muscle cell dysfunction plays an important role in the pathogenesis of asthma, and that treatment with inhaled corticosteroids reverses the abnormalities in airway smooth muscle cell function.
NCT02749565
The investigators will compare the circulating fibrocyte proportion in asthmatic patients with obstructive sleep apnea (OSA) and not with OSA In addition, the investigators will compare the expression of epidermal growth factor receptor (EGFR), endothelin A receptor (ETAR) and connective tissue growth factor (CTGF) The association of those factors and annual decline of forced expiratory volume in 1 second (FEV1) will be performed
NCT04084613
A prospective multi-centre, non-interventional observational study, that will be conducted in several centers in Greece for a 2-year time period (completion date December 2020), to describe patient characteristics, medical history, and the clinical benefit of mepolizumab in patients with severe eosinophilic asthma newly initiated to the drug.
NCT02153359
This study is about asthma and how the environment affects asthma. Scientists know that air pollution (such as cigarette smoke and other particles in the air) can make asthma symptoms worse. This research is being done to study how the health of a person with asthma responds to an air cleaner. The investigator hypothesize that an air cleaner will improve the health of persons with asthma.
