Abstract:
Objective To explore the correlation between serum vitamin D levels,vitamin D receptor gene polymorphism,and the incidence of chronic urticaria in children,and to provide clinical evidence for screening the genetic susceptibility of chronic urticaria in children.Methods Clinical data and peripheral blood samples were collected from 100 children with chronic urticaria in the test group and 100 healthy children in the control group who were admitted to the Dermatological Department of Pingshan Distinct Maternal and Child Health Hospital from December 2021 to January 2023.Chemiluminescent assays were used to measure the levels of 25(OH)D,IgE and IgG.PCR amplification was performed to amplify the VDR gene polymorphic sites ApaI,BsmI,TaqI,FokI,and Tru9I,followed by sequencing to assess the VDR gene polymorphism and the expression levels of the associated genetic polymorphic sites rs7975232,rs1544410,rs731236,rs2228570,and rs757343.Results The levels of 25(OH)D in the test group were lower than that in the control group,while IgE and IgG levels were higher than those in the control group,and the differences were statistically sig-nificant.Multivariate logistic regression analysis showed that the T allele of rs757343 was a risk factor for the incidence of chronic urticaria in children(OR=1.45 8,95%CI:1.015-2.153,P=0.047),while the CC geno-type of rs757343 and 25(OH)D were protective factors(OR=0.250,95%CI:0.056-0.786,P=0.031;OR=0.553,95%CI:0.373-0.713,P<0.001).ROC curve analysis showed that the area under the curve for 25(OH)D,white blood cell count,neutrophil percentage,lymphocyte percentage,and basophil percentage were 0.928,0.701,0.808,0.797 and 0.753,all>0.7.Conclusion Vitamin D can assist in the diagnosis of uricaria in children and evaluate the progression of the disease.25(OH)D is a protective factor for the onset of chronic urticaria in children,the T allele of the VDR gene polymorphism rs757343 is a risk factor for chronic urticaria in children,while the CC genotype is a protective factor.
