Abstract:
Objective To explore the association between rs750064,rs1078761 loci polymorphisms of BPI fold containing family A member 1(BPIFA1)gene and susceptibility to asthma in pediatric patients with allergic rhinitis(AR).Methods A total of 136 cases of AR admitted to Heping Hospital Affiliated to Changzhi Medical College from March 2021 to May 2024,aged 2～10 years old,were selected as the observation group,including 70 cases of asthma with AR,the control group was 66 cases with AR alone.The laboratory indicators of the children were collected,the rs750064 and rs1078761 loci of BPIFA1 gene were genotyped by MassArray System.The differences in genotype distribution and allele frequency between the two groups were compared.The correlation between rs750064 and rs1078761 loci of BPIFA1 gene and susceptibility to asthma in children with AR was analyzed by unconditional Logistic regression.Results Compared with the control group,interleukin-6(IL-6),fractional exhaled nitric oxide(FeNO)and immunoglobulin E(IgE)levels in the observation group were significantly increased,while forced vital capacity(FVC)levels were significantly decreased,with statistical significance(t=-22.648～4.879,all P<0.05).The genotypes of rs750064 and rs1078761 of BPIFA1 gene in control group and observation group were in line with Hardy-Weinberg equilibrium law(χ2=1.492～5.549,all P>0.05),indicating population representation.The distribution frequencies of allele T and genotype TT at rs750064 of BPIFA1 gene and allele A and genotype AA at rs1078761 locus in the observation group were higher than those in the control group,and the differences were statistically significant(χ2=8.251～10.273,all P<0.05).The results of unconditional Logistic regression showed that in the co-dominant model(CC vs CT)of rs750064,the risk of CC genotype carriers was lower than that of TT genotype carriers(OR=0.537,95%CI:0.276～1.804).In the dominant model(CT+CC vs TT)and the recessive model(CT+TT vs CC),rs750064 polymorphism was associated with the risk of AR with asthma(all P<0.05).In the co-dominant model(GG vs AG),the risk of rs1078761 in GG genotype carriers was lower than that in AA genotype carriers(OR=0.498,95%CI:0.176～1.205).Under the dominant model(AG+GG vs AA)and recessive model(AG+AA vs GG),rs1078761 polymorphism was associated with the risk of AR combined asthma with statistical significance(all P<0.05).After adjusting various factors,rs750064 and rs1078761 were associated with the risk of AR combined with asthma under the three genetic models,and the differences were statistically significant(all P<0.05).Conclusion The polymorphism of BPIFA1 gene is significantly related to the susceptibility of asthma in children with AR.TT carriers of rs750064 locus and AA carriers of rs1078761 locus are more likely to develop asthma in children with AR.
