Effects of ADRB2 gene regulatory region polymorphism on the efficacy of SABA in the treatment of acute asthma attack in children
gene regulatory region polymorphism on the efficacy of short-acting beta 2 receptor agonists (SABA) in the treatment of acute asthma attack in children.
METHODS
2
A total of 127 children with acute mild to moderate bronchial asthma who received SABA treatment for 7 days in the General Hospital of Northern Theater Command from October 2016 to October 2020 were selected to detect their genotype distribution and compare the improvement of pulmonary functional indicators and curative effect among different genotypes. The effect of the high-order interaction of gene polymorphism on therapeutic effect was investigated.
RESULTS
2
Among 127 children, there were 80, 44 and 3 cases of TT, TA and AA types at locus rs2895795, 93, 32 and 2 cases of CC, CG and GG types at locus rs11168070, and 41, 64 and 22 cases of GG, GA and AA types at locus rs12654778, respectively, in accordance with Hardy-Weinberg equilibrium (
P
>0.05). After treatment, the improvement rate of the peak expiratory flow in percent predicted value (PEF%pred) and the improvement rate of the forced expiratory flow at 75% vital capacity in percent predicted value (FEF75%pred) in children with TA type were significantly lower than that of TT type at locus rs2895795 (
P
<0.05); the improvement rates of PEF%pred and FEF75%pred in children with CG type were significantly lower than that of CC type at locus rs11168070 (
P
<0.05); the improvement rates of PEF%pred in children with GA and AA type were significantly lower than that of GG type at locus rs12654778 (
P
<0.05). The differences in fractional exhaled nitric oxide before and after treatment were not statistically significant among different genotypes at each locus (
P
>0.05). The proportion of remarkable improvement of children with TT type at locus rs2895795 was 2.358 times that of children with TA+AA type (
P
<0.05), and there was no significant effect of higher-order interaction of
ADRB2
polymorphism on the efficacy in children with asthma (
P
>0.05).
CONCLUSIONS
2
Polymorphisms in the regulatory region of the
ADRB2
gene in children with bronchial asthma are associated with the efficacy of SABA in the treatment of acute asthma attack in children. At locus rs2895795, rs11168070 and rs12654778, the improvement of lung function of children with wild-type is more obvious, and the efficacy of SABA treatment on children with TT type is better at locus rs2895795.
