A meta-analysis of the correlation between the HLA-DRB1*03 allele and chronic hepatitis B in the Han Chinese population.

OBJECTIVE

This study sought to use a meta-analysis approach to comprehensively evaluate correlations between the human leukocyte antigen-DR beta 1 (HLA-DRB1)*03 allele and chronic hepatitis B (CHB) in the Han Chinese population.

METHODS

The China Biomedical Literature database (CBMdisc), the Chongqing VIP database (VIP), and the PubMed database were searched. Using the inclusion and exclusion criteria of this study, all relevant case-control studies retrieved in these searches that satisfied the conditions of this investigation were collected. Review Manager (RevMan) 5.2 software was used to conduct a meta-analysis on the results of these studies.

RESULTS

There were 9 publications that satisfied the inclusion criteria. These publications included a total of 970 cases in the CHB group and 1185 cases in the normal control group. Egger's test revealed no significant publication bias. A comprehensive analysis indicated that the pooled odds ratio (OR) value was 1.94 with a 95% confidence interval (CI) of 1.23-3.06 (Z=2.84, p=0.004); these findings suggested that in the Han Chinese population, the HLA-DRB1*03 allele is a susceptibility allele related to the occurrence of CHB.

CONCLUSION

There is a statistically significant correlation between the HLA-DRB103 allele and the occurrence of CHB in the Han Chinese population, and the HLA-DRB103 allele may be a susceptibility allele for this disease.
