ABSTRACT
OBJECTIVE: This study aimed to investigate the pathogenesis of geriatric asthma through immunoglobulin E (IgE), interleukin-17A (IL-17A), IL-17F, and glucocorticoid receptor-ß (GR-ß) expression. METHODS: We studied 51 geriatric male patients with asthma and 50 young male patients with asthma. We also included 21 normal geriatric males and 21 normal young males. All geriatric and young patients were divided into groups according to pulmonary function. Levels of cytokines, such as IgE, IL-17A, IL-17F, and GR-ß, were measured. Pulmonary function was assessed. The results from patients were compared with those from the 42 healthy subjects. RESULTS: Serum IgE, IL-17A, IL-17F, and GR-ß levels in geriatric patients with moderate or severe asthma were significantly higher than those in young patients with moderate asthma and in the normal population. Geriatric patients with asthma had higher asthma control test scores than did young patients with asthma. CONCLUSION: Hormone resistance in geriatric male patients with asthma is more serious than that in young male patients with asthma. Airway inflammation and airway remodeling in geriatric male patients with asthma may be more serious than those in young male patients with asthma, even when there is similar pulmonary function.
