Background/Aim: To assess the correlation between serum HBsAg titers and hepatitis B virus (HBV) DNA levels in patients with hepatitis B envelop antigen‐negative (HBeAg −ve) HBV genotype‐D (HBV/D) infection. Patients and Methods: A total of 106 treatment‐ naïve, HBeAg −ve HBV/D patients were included; 78 in the inactive carrier (IC) state and 28 in the active hepatitis (AH) stage. HBV DNA load and HBsAg titers were tested using TaqMan real‐time polymerase chain reaction (PCR) and automated chemiluminescent microparticle immunoassay, respectively. Results: The median (range) log10 HBsAg titer was significantly lower in the IC group compared with AH group, 3.09 (−1 to –4.4) versus 3.68 (−0.77 to 5.09) IU/mL, respectively; P < 0.001. The suggested cutoff value of HBsAg titer to differentiate between the two groups was 3.79 log10 IU/mL. In addition, there was a significant positive correlation between HBsAg and HBV DNA levels in the whole cohort, AH, and IC groups (r = 0.4, P < 0.0001; r = 0.591, P = 0.001; and r = 0.243, P = 0.032, respectively). Conclusion: Serum HBsAg titers may correlate with HBV DNA in treatment‐naïve HBeAg –ve HBV/D patients, and supports the use of HBsAg levels in clinical practice as a predictor of serum HBV DNA levels.
