Abstract:
Objective To study the allele and genotype distribution of CD14 gene promoter region-159C/T,-260C/T polymorphisms in Chinese patients with Henoch-Schonlein purpura(HSP),and to discuss the association between CD14 gene promoter region polymorphisms and HSP.Methods Under the case-control study,CD14-159C/T and CD14-260C/T site polymorphisms in 144 children with HSP and 180 healthy controls were analyzed with polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP),and the relationship between CD14-159C/T and CD14-260C/T site polymorphisms and the risk of HSP were analyzed.SPSS 13.0 software was used to analyze the data.Results The distribution of CD14 gene-159C/T polymorphism was significantly different between gastro-intestinal(GI)involvement group,renal involvement group and healthy control group(P=0.041,0.010,respectively);but the CD14 gene-260C/T polymorphism was significantly different between simple lesion group,renal involvement group and healthy control group(P=0.003,0.037,respectively)and C and T allele were significantly different between simple lesion group,joint damage group,GI involvement group,renal involvement group,healthy control group(P=0.017,0.035,0.024,0.007)and the relative risk for different types of HSP in T allele carriers was higher than that in C allele carriers(simple lesion:OR=2.097,95%CI 1.131-3.823;joint:OR=1.603,95%CI 1.031-2.493;GI:OR=1.602,95%CI 1.062-2.415;renal:OR=1.843,95%CI 1.175-2.889;respectively).Conclusions CD14 gene promoter region polymorphism is associated with HSP and T alele of CD14-260C/T may be a risk factor for HSP.
