Background. Hepatitis B virus (HBV) remains one of the most serious and prevalent health problems in the world. Objectives. To determine the serum hepatitis B virus (HBV) RNA levels in patients with chronic hepatitis B (CHB) with low HBV DNA levels and analyze the influencing factors. Materials and methods. Seventy-two CHB patients with low HBV DNA levels were enrolled and divided into 2 groups according to hepatitis B e antigen (HBeAg) status; their age, sex, the incidence of HBV RNA level < lower limit of detection (LLD), and serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), quantitative determination of HBsAg (qHBsAg), HBV DNA, and HBV RNA levels were compared. The factors influencing serum HBV RNA levels < LLD and the correlation between serum HBV RNA levels, and serum ALT, AST, qHBsAg and HBV DNA levels were analyzed. Results. In HBeAg-positive patients, serum AST, qHBsAg and HBV RNA levels were higher, and serum HBV DNA levels and incidence of HBV RNA < LLD were lower than those in HBeAg-negative patients (p < 0.05). Multivariate linear regression analysis revealed that HBeAg is a factor that significantly influences serum HBV RNA levels in patients with CHB (p < 0.05). Multivariate logistic regression analysis indicated that HBeAg and qHBsAg are factors that influence serum HBV RNA levels < LLD in patients with CHB. In HBeAg-positive patients, serum HBV RNA levels were positively correlated with qHBsAg and HBeAg. Conclusions. The serum HBV RNA levels in CHB patients with low HBV DNA levels varied according to HBeAg status. The HBeAg is a factor that significantly influences serum HBV RNA levels in patients with CHB, while HBeAg and qHBsAg are factors that significantly influence serum HBV RNA levels < LLD in patients with CHB.
