Over half (55.7%) had uncontrolled asthma as measured by ACT/cACT; 13.9% had a normal ACT/cACT score but were uncontrolled using the Asthma Control Questionnaire and 20.2% were controlled on both measures but had received oral steroids in the past year for asthma.
Statistically significant reductions in self-reported environmental asthma triggers and health improvements were found in the following areas: doctor visits, use of antibiotics for chest problems, respiratory symptoms and quality of life indicators, and asthma control (ACT score).
Discovered DMRs annotated to genes implicated in allergic asthma, Th2 activation and eosinophilia (EPX, IL4, IL13) and genes previously associated with asthma and IgE in EWAS of blood (ACOT7, SLC25A25).
On the contrary, gender, FEV<sub>1</sub>, FEV<sub>1</sub>/FVC ratio, FEF<sub>25-75</sub>, ACT, VAS of breathing perception, oral corticosteroid use, and asthma severity grade were associated with the asthma control grade.
Among women who completed the ACT during the clinical interview, the 50% of women who experienced worsening asthma during pregnancy (6/12) had an ACT score below 20.
Validity indicators were calculated at different C-ACT cut-points to determine those most appropriate for predicting controlled and uncontrolled asthma.
No significant correlations were observed between FeNO levels and other parameters (Asthma Control Test [ACT] score or forced expiratory volume in one second [FEV<sub>1</sub>]) in mean and percentage change of values under treatment of asthma; however, significant positive correlations were found between ACT scores and FEV<sub>1</sub>.
In FP/FORM-treated patients aged ≥12 years, asthma control (Asthma Control Test™ [ACT]), incidence of severe exacerbations, lung function, quality of life (asthma quality of life questionnaire [AQLQ]) and adverse events (AEs) were assessed over one year.
Measurements included fraction of exhaled nitric oxide (FENO, ppb), dynamic and static lung function, and bronchial provocation with methacholine (PD:20) and mannitol (PD:15), as well as an evaluation of respiratory symptoms using the asthma control test (C-ACT).
The frequency of VDR ApaI aa genotype was significantly higher in controlled asthma group (n=92) than uncontrolled asthma group (n=35), according to C-ACT (24.5% vs 0.0%, p<0.001) and GINA (32.7% vs 7.5%, p=0.001).
Results from GENEHUNTER, SOLAR, and ACT software packages are compared for the quantitative trait immunoglobulin E (IgE) using chromosome 5 asthma familial data from Oxfordshire (England), Perth (Australia), and Freiburg (Germany), and using the genome-wide German data.
Among heterozygotes, the prevalence of asthma in first and second degree relatives with low plasma alpha 1-antichymotrypsin concentration was higher than in relatives with normal plasma ACT concentration, but the difference in prevalence did not reach statistical significance [prevalence ratio 3.1 (0.96-9.83), P = 0.059].
