Purpose: To evaluate the association of Chronic hepatitis B virus (HBV) infection and chronic kidney disease (CKD).
Methods: We searched Embase, Grateful Med, Ovid, PubMed, and the China Biological Medicine Database. A meta-analysis was performed to assess whether HBV infection plays an independent impact on the development of CKD in the general population. Relative risks of CKD (defined as reduced glomerular filtration rate or proteinuria) according to HBsAg serologic status were studied.
Results: Six eligible clinical studies (189,709 individuals in total) were included in the analysis. There was no association between HBsAg seropositive status and prevalence of CKD, the summary estimate for adjusted relative risk (RR) was 1.16 (95% confidence interval (CI), 0.78, 1.71; p = .46) according to the random-effects model, and between studies heterogeneity was noted (p values by Q test <0.001). Also, there were no significant associations between positive HBV serologic status and low eGFR (adjusted relative risk, 0.95; 95% CI, 0.72, 1.26; p = .72) or proteinuria (adjusted relative risk, 1.00; 95% CI, 0.83, 1.20; p = .99).
Conclusions: This meta-analysis shows that there was no association between exposure to HBV and the risk of developing CKD in Asian populations.
