摘 要:目的 探讨人类白细胞抗原(HLA) -Cw等位基因与炎症性肠病(IBD)的相关性,以期发现IBD的易感基因。方法 采用序列特异性引物聚合酶链反应(PCR-SSP)方法,对100例溃疡性结肠炎(UC)、73例克罗恩病(CD)和106例健康对照进行HLA-Cw基因分型。结果 UC患者组HLA-Cw* 07基因表型频率为0.430,明显高于健康对照组(0.226),P=0.002;CD患者组HLA-Cw* 12基因表型频率为0.356,明显高于健康对照组(0.123),P=0.000。结论 HLA-Cw* 07基因可能与UC易感性密切相关;HLA-Cw*12基因可能与CD易感性密切相关。Objective To investigate the association of HLA-Cw alleles with inflammatory bowel disease(IBD), so as to identify IBD susceptibility gene.Methods The HLA-Cw genotype were analyzed in 100 patients with ulcerative colitis (UC), 73 patients with Crohn's disease (CD) and 106 randomly ethnically matched healthy controls by sequence specific primer polymerase chain (PCR-SSP).Results HLA-Cw * 07 gene phenotype frequencies increased in patients with UC (0.430) compared with that in healthy controls (0.226), P = 0.002; while HLA-Cw * 12 gene phenotype frequencies increased in patients with CD (0.356) compared with that in healthy controls (0.123), P = 0.000.Conclusion HLA-Cw * 07 allele and HLA-Cw * 12 allele may be strongly associated with the susceptibility of UC and CD, respectively.
