Meta-Analysis of the Relationship Between HLA-DRB1*07and HLA-DRB1*13 Gene Polymorphisms, and Chronic Hepatitis B in Chinese Han Population
Objective:To assess the relationship of HLA-DRB1*07 and HLA-DRB1*13 gene polymorphisms with chronic hepatitis B (CHB) in Chinese Han population Methods: A comprehensive search for articles from 2000 to 2015 was conducted from China National Knowledge Infrastructure (CNKI), VIP and Medline databases. Ten epidemiological case-control studies on the relationship between gene polymorphisms of HLA-DRB1*07 and HLA-DRB1*13, and CHB were subjected to meta analysis. Potential publication bias was analyzed with Review Manager 5.3 software and stata software. Results: A total of 838 patients with CHB and 1181 uninfected healthy controls were included from the ten studies. HLA-DRB1*07 alleles were the risk factors of CHB, with pooled odds ratio of 2.09 (95% CI=1.26~3.47;Z=2.86,P<0.01). HLA-DRB1*13 alleles were the protection factors against CHB, and the value of pooled odds ratio was 0.32 (95% CI=0.19~0.57;Z=3.94,P<0.01) Conclusion: CHB is associated with gene polymorphism of HLA-DRB1 in Chinese Han population. HLA-DRB1*07 alleles were the risk factors of CHB, while HLA-DRB1*13 alleles were the protection factors against the disease.
