ABSTRACT
OBJECTIVE To investigate the association between the functional GLCCI1 gene rs37973 polymorphism and inhaled corticosteroids (ICSs) response in patients with asthma-chronic obstructive pulmonary disease overlap (ACO). METHODS Totally 173 newly diagnosed ACO patients were recruited from Shanghai Pudong New Area People’s Hospital during April 1st, 2019 to December 31st, 2020. All patients were treated with Salmeterol fluticasone inhalation powder, twice a day, for 24 weeks. The genotype of rs37973 locus was determined, and lung function indicators [forced expiratory volume in one second (FEV1), FEV1/forced vital capacity (FVC), the percentage of FEV1 to expected value (FEV1%pred)], and lung function improvement (ΔFEV1 and ΔFEV1%pred) were all detected. RESULTS Totally 111 patients completed the whole 24-week follow-up and lung function detection. Among them, there were 42 cases of AA genotype, 52 cases of AG genotype, and 17 cases of GG genotype. After 12, 24 weeks of treatment, lung function indexes of patients were significantly better than baseline lung function indexes before treatment (P<0.05). After 24 weeks of treatment, ACO patients with AA and AG genotypes showed significantly better lung function improvement than GG genotype, and ΔFEV1%pred of AA genotype was significantly better than AG genotype (P< 0.05). After 12, 24 weeks of treatment, the improvement of lung function in patients with a smoking history ≤20 pack year was significantly better than those with a smoking history >20 pack year, and among patients with a smoking history ≤20 pack year, only AA genotype had significantly better FEV1%pred than AG genotype (P<0.05). After 12 weeks of treatment, among patients with a smoking history >20 pack year, the improvement of lung function in AA genotype and AG genotype was significantly better than GG genotype, and the FEV1%pred in AA genotype was significantly better than AG genotype (P<0.05). After 24 weeks of treatment, the improvement of lung function of AA genotype and AG genotype was significantly better than GG genotype (P<0.05). CONCLUSIONS GG genotype of GLCCI1 gene rs37973 locus is associated with the poor treatment response to ICSs in patients with ACO, especially in patients with smoking history >20 pack year.
