目的 研究人类白细胞抗原 (HLA)DRB1等位基因与幽门螺杆菌 (Hp)感染的关系。 方法 用BioseedHp IgG定量酶联免疫试剂盒检测 46例胃癌、75例食道癌和100例人群对照的Hp IgG抗体,用Biotest低解析水平HLA DRB酶联免疫探针杂交测定试剂盒检测HLA DRB1等位基因。结果 (1)Hp IgG阳性组DRB108基因频度显著高于Hp IgG阴性组 (13.1%vs 4.4% ;χ2 =11.14,P<0.001)。Hp IgG阳性组DRB1 12基因频度显著低于Hp IgG阴性组 (5.4%vs 11.3 % ;χ2 =4.49,P <0.05 )。(2)胃癌组中DRB1 0 2基因频度显著高于对照组,而DRB107基因频度显著低于对照组,但在胃癌、对照的Hp IgG阳性组和Hp IgG阴性组之间的DRB1 02、DRB107基因频度差异均无显著性。结论 (1)HLA DRB108基因阳性可能增加对Hp的易感性,DRB1 12基因可能是抵御Hp感染的保护性基因。 (2)DRB102基因阳性可能是胃癌的宿主遗传危险因素、DRB107基因可能是胃癌的保护性因素,但DRB102、DRB107基因与胃癌的联系和Hp感染无关 |

Objective In order to study the relation between human leukocy te antigen (HLA)DRB1 alleles and Helicobacter py lori (Hp)infection.Methods Hp-I gG antibody from 46 g astric cancer(GC), 75 esophageal cancer and 100 population-based controls w ere identified by Hp-I gG quantitative enzyme immunoassay.Biotest HLA-DRB enzyme linked probe hybridization assay kit (low resolution)w as used to identify DRB1 alleles.Results (1)Frequency of DRB1 *08 was sig nificantly higher in Hp-IgG positive g roup than in Hp-IgG neg ative group (13.1% vs 4.4 %, χ2 =11.14, P <0.001).Frequency of DRB1 *12 w as sig nificantly lower in Hp-IgG positive g roup than in Hp-IgG negatives (5.4 % vs 11.3%,χ2 =4.49, P <0.05).(2)Frequency of DRB1 *02 in GC was significantly higher than that of controls. Frequency of DRB1 *07 in GC was sig nificantly lower than that of controls.However, neither the frequency of DRB1 *02 between Hp-IgG positive and Hp-I gG negative groups nor the frequency of DRB1 *07 betw een Hp-IgG positive and Hp-IgG negative g roups show ed significant differences in GC and controls.Conclusions (1)HLA-DRB1 *08 mig ht serve a gene tic risk factor for Hp infection while DRB1*12 mig ht play a role of pro tecting effect against Hp infection.(2)DRB1 *02 mig ht be a genetic risk factor fo r GC w hile DRB1 *07 might play a role of protecting effect against GC.However, the relations between DRB1 *02, DRB1*07 and GC were not associated with Hp infection. |
