RESUMO

OBJECTIVE: To explore the relationships between hepatitis B virus (HBV) DNA, HBV RNA and hepatitis B surface antigen (HBsAg) and to evaluate their predictive value for mother-to-child transmission of HBV. DESIGN: An observational cohort study. SETTING: First Hospital of Jilin University. POPULATION: HBsAg-positive and hepatitis B e antigen (HBeAg) -positive pregnant women were recruited. METHODS: Blood samples were collected from mothers before delivery, and HBV infection of infants was evaluated at 7 months of age. RESULTS: Overall, 268 mothers and 271 infants were enrolled. HBV DNA and HBsAg levels were correlated (rs = 0.699; P < 0.001), and HBV DNA (rs = 0.500; P < 0.001) and HBsAg (rs = 0.372; P < 0.001) were both correlated with HBV RNA. The areas under the curve for HBV DNA, HBsAg and HBV RNA for prediction of infection were 0.69 (95% CI 0.57-0.82), 0.63 (95% CI 0.51-0.76) and 0.65 (95% CI 0.52-0.78), respectively. Higher HBV DNA (odds ratio [OR] 4.77, 95% CI 1.44-15.86), higher HBsAg (OR 4.13, 95% CI 1.12-15.25) and higher HBV RNA (OR 3.19, 95% CI 1.09-9.32) were risk factors for HBV infection. Analysis of the HBV DNA-RNA-HBsAg Score revealed that it was an independent predictive factor for mother-to-child transmission (the OR of Score 3 was 8.81, 95% CI 2.79-27.82). CONCLUSION: HBV DNA, HBV RNA and HBsAg were correlated in HBeAg-positive pregnant women. HBsAg could be considered as a substitute marker of HBV DNA for HBeAg-positive pregnant women in low-income regions. We should pay special attention to pregnant women with high levels of all three markers. TWEETABLE ABSTRACT: HBsAg could be considered as a substitute marker of HBV DNA for HBeAg-positive pregnant women in low-income regions. Special attention should be given to pregnant women with high levels of all three markers (HBV DNA, HBV RNA and HBsAg).
