Correlation between HLA-DQB1 and HLA-DRB1 gene polymorphisms and caries: a systematic review and Meta-analysis
Abstract
Objective Systematic evaluation of the correlation of HLA-DQB1 and HLA-DRB1 allele polymorphisms with caries, to provide reference for caries prevention and treatment. Methods Relevant literature published before December 2020 was searched in the Cochrane Library, PubMed, Embase, Web of Science, Scopus, CNKI, Wanfang, VIP, and CBM databases. Meta-analysis was performed using the R4.0.2 software to test for heterogeneity and evaluate the publication bias. Results In total,10 case-control studies were included with 564 people in the case group and 676 people in the control group. The results of the Meta-analysis show that: ① HLA-DQB1*02 (OR=0.52, 95%CI=0.29-0.93, P < 0.05) and HLA-DRB1*09 (OR=0.34, 95%CI=0.21-0.58, P < 0.05) are protective factors of dental caries; ② HLA-DRB1*13 (OR=2.96, 95%CI=2.03-4.33, P < 0.05) and HLA-DRB1*14 (OR=1.95, 95%CI=1.26-3.02, P < 0.05) alleles are risk factors for the development of dental caries. The results of the subgroup analysis are: HLA-DRB1*07 is a caries susceptibility factor in the Chinese population (OR=0.48, 95% CI=0.24-0.97, P < 0.05), while it is not statistically significant in the Brazilian and Turkish populations; HLA-DRB1*11 is a caries protective factor in the saliva group (OR=2.26, 95% CI=1.46-3.52, P < 0.05). 3.52, P < 0.001), while it is a caries susceptibility factor in the blood group (OR=0.09, 95% CI=0.12-0.34, P < 0.001). Conclusion HLA-DRB1*13 and HLA-DRB1*14 alleles are caries susceptibility genes, and HLA-DQB1*02 and HLA-DRB1*09 have protective effects on the caries development. HLA-DRB1*07 is a caries susceptibility gene in the Chinese population; HLA-DRB1*11 is a caries protective gene in the saliva group. Due to the limited sample size and quality of the included studies, more high-quality studies will be included later for verification.
