ABSTRACT

AIM:

To elucidate the relationship between childhood asthma susceptibility and clinical efficacy of inhaled glucocorticoids (ICS) in children with different genotypes of asthma by exploring rs776746 and rs15524 single nucleotide polymorphisms (SNPs) of cytochrome P450 enzyme 3A5 (CYP3A5) gene in asthmatic children and healthy children.

METHODS:

The CYP3A5 gene rs776746 and rs15524 polymorphic sites were detected in 79 children (Case group) with asthma of Han nationality and 100 healthy children (Control group) who met the inclusion criteria admitted to the Northern Theater General Hospital in Northeast China from October 2016 to October 2020, and genotype, allele and linkage analysis were performed. The case group was given inhaled glucocorticoids by nebulised inhalation for 3 months, and lung function and exhaled breath nitric oxide (FeNO) were measured at entry and after treatment, and asthma control score C-ACT/ACT was done after treatment, so as to compare the prevalence of different genotypes and the differences in the above test index scores.

RESULTS:

There was complete linkage disequilibrium at rs776746 and rs15524 loci. There were three genotypes of T/T, T/C and C/C at rs776746 locus of CYP3A5 gene. There were significant differences in the frequency of different genotypes between the case group and the control group
