摘要
目的:探讨腹泻型肠易激综合征(IBS)患者乳糜泻(CD)的发病与血清抗麦胶抗体(IgG-AGAs)、血清抗组织转谷氨酰胺酶抗体(IgA-tTGs)的相关性及HLA-DQ基因SNP rs2187668位点多态性与乳糜泻的关系。同时探讨中国腹泻型组人群HLA-DQ基因SNP位点(rs2187668)基因型与等位基因频率分布。方法:采用ELISA法对73例腹泻型IBS病例进行血清学IgG-AGAs、IgA-tTGs检测,采用TaqMan-PCR方法检测腹泻型IBS病例HLA-DQ基因SNP位点(rs2187668)基因型与等位基因频率的分布。结果:73例乳糜泻患者中有7例(9.6%)乳糜泻抗体阳性,其中5例(6.8%)IgG-AGAs阳性,合并IDDM-IgG-AGAs阳性1例(1.4%),2例(2.7%)IgA-tTGs阳性,1例(1.4%)2种抗体均为阳性。71例腹泻型IBS组(A型为4.93%)和正常对照组(A型为3.64%)在位点rs2187668上基因型和等位基因频率组间分布差异无统计学意义(P>0.05)。7例血清学阳性患者中,1例IgA-tTGs阳性患者rs2187668位点含有A等位基因。结论:血清IgG-AGAs和IgA-tTGs检测可辅助诊断免疫性乳糜泻,对早期诊断麸质敏感的免疫性乳糜泻具有积极的意义。
Objective= To investigate the association of anti-gliadin antibodies (IgG-AGAs) and an- ti-tissue transglutaminase antibodies (IgA-tTGs) with celiac disease and the correlation of rs2187668 to IgA-tTG and IgG AGA in Chinese suspected CD patients. Methods.. The anti-gliadin antibodies (IgG-A- Gas) and anti-tissue transglutaminase antibodies (IgA-tTGs) of 73 diarrhea-predominant irritable bowel syndrome patients were detected by ELISA. Samples were genotyped for rs2187668 (assay C__58662585_ 10) using the TaqMan method according to the protocol for the ABI PRISM 7900HT Sequence Detection
