We investigated the association of human leukocyte antigen (HLA) II (DRB1 and DQB1) alleles with susceptibility to human papillomavirus (HPV)-associated cervical precancer and cancer cases in a hospital-based case-control study in a northern Indian population. A total of 202 subjects, including 100 patients comprising 31 cervical precancer (cervical intraepithelial neoplasia [CIN] 2/3) and 69 invasive cervical cancer cases, and 102 healthy controls participated in the study. Both patients and controls were screened for HPV infection using a polymerase chain reaction (PCR-based approach. Low-resolution PCR-sequence specific priming (PCR-SSP) was used to genotype HLA II (DRB1 and DQB1). Our results demonstrate that the DRB115 allele/DRB115-DQB106 haplotype may have a predisposition for HPV infection (p(c) < 0.05) or cervical cancer/precancer (p(c) < 0.05) development, whereas the DRB104 allele/DRB104-DQB103 haplotype might exhibit susceptibility to cervical precancerous lesions (p(c) < 0.05). The DRB113 allele/DRB113-DQB1*06 haplotype was strongly protective against risk to HPV infection (p(c) < 0.002) as well as cervical cancer (p(c) 0.01). Therefore, we have demonstrated that HLA DR-DQ polymorphisms are involved in genetic susceptibility to cervical cancer or HPV infection in a northern Indian population.
在一项针对印度北部人群的基于医院的病例对照研究中,我们调查了人类白细胞抗原(HLA)II类(DRB1和DQB1)等位基因与人类乳头瘤病毒(HPV)相关的宫颈上皮内瘤变和癌症易感性之间的关联。共有202名受试者参与了该研究,其中包括100例患者,其中31例为宫颈上皮内瘤变(CIN 2/3),69例为浸润性宫颈癌患者,以及102名健康对照。使用聚合酶链反应(基于PCR的方法)对患者和对照进行HPV感染筛查。采用低分辨率PCR序列特异性引物(PCR-SSP)对HLA II类(DRB1和DQB1)进行基因分型。我们的结果表明,DRB115等位基因/DRB115-DQB106单倍型可能易患HPV感染(p(c)<0.05)或宫颈癌/癌前病变(p(c)<0.05),而DRB104等位基因/DRB104-DQB103单倍型可能对宫颈上皮内瘤变易感(p(c)<0.05)。DRB113等位基因/DRB113-DQB1*06单倍型对HPV感染风险(p(c)<0.002)以及宫颈癌(p(c) 0.01)具有很强的保护作用。因此,我们证明了HLA DR-DQ多态性参与了印度北部人群对宫颈癌或HPV感染的遗传易感性。
