Abstract Objective To assess on-treatment serum HBsAg and HBV DNA kinetics in HBeAg-positive CHB patients to predict the efficacy of pegylated interferon (PEG-IFN) in early phase of treatment. Methods Forty-one treatment-naive HBeAg-positive patients treated with PEG-IFNα 2a at a dose of 180 μg/week for at least 24 weeks were evaluated. Their treatment response was assessed, including normalization of serum ALT, decline of serum HBV DNA and loss of HBeAg. Results We found that a decrease of HBV DNA level at the 4th week was positively correlated with the decrease of HBV DNA level at the 12th week and 24th week (r = 0.8202, P < 0.0001 and r = 0.6838, P < 0.0001, respectively). We observed that a decrease of HBsAg level at the 4th week was positively correlated with decrease of HBsAg level at the 12th week and 24th week (r = 0.4868, P = 0.0023 and r = 0.4251, P = 0.0109, respectively). A decrease of HBsAg level at the 24th week was positively correlated with the decrease of HBV DNA level at the 24th week (r = 0.5262, P = 0.0024). Serum level of IFN and IFN neutralizing antibody had no relationship with HBV DNA or HBsAg titers kinetics. Conclusions The decline of serum HBV DNA and hepatitis B surface antigen at the 4th week can be used to predict the response to PEG-IFNα 2a in patients with HBeAg positive chronic hepatitis B.

Objective. To determine the efficacy and safety of Lingmao Formula combined with entecavir for HBeAg-positive chronic hepatitis B patients with mildly elevated alanine aminotransferase (ALT).Methods. 301 patients were randomly assigned to receive Lingmao Formula combined with entecavir (treatment group) or placebo combined with entecavir (control group) for 52 weeks. The outcomes of interest included the reduction of serum HBV DNA level, HBeAg loss, HBeAg seroconversion, ALT normalization, and histological improvement.Results. The mean decrease of serum HBV DNA level from baseline and the percentage of patients who had reduction in serum HBV DNA level ≥2 lg copies/mL in treatment group were significantly greater than that in control group (5.5 versus 5.4 lg copies/mL,P=0.010; 98.5% versus 92.6%,P=0.019). The percentage of HBeAg loss in treatment group was 22.8%, which was much higher than a percentage of 12.6% in control group (P=0.038). There was no significant difference between the two groups in histological improvement. Safety was similar in the two groups.Conclusions. The combination of Lingmao Formula with entecavir could result in significant decrease of serum HBV DNA and increase of HBeAg loss for HBeAg-positive chronic hepatitis B patients with mildly elevated ALT without any serious adverse events. Clinical trial registration number isChiCTR-TRC-09000594.

AbstractBackground(Pegylated) Interferon ([Peg]IFN) therapy leads to response in a minority of chronic hepatitis B (CHB) patients. Host genetic determinants of response are therefore in demand.MethodsIn this genome-wide association study (GWAS), CHB patients, treated with (Peg)IFN for at least 12 weeks ± nucleos(t)ide analogues within randomized trials or as standard of care, were recruited at 21 centers from Europe, Asia, and North America. Response at 24 weeks after (Peg)IFN treatment was defined as combined hepatitis B e antigen (HBeAg) loss with hepatitis B virus (HBV) DNA <2000 IU/mL, or an HBV DNA <2000 IU/mL for HBeAg-negative patients.ResultsOf 1144 patients, 1058 (92%) patients were included in the GWAS analysis. In total, 282 (31%) patients achieved the response and 4% hepatitis B surface antigen (HBsAg) loss. GWAS analysis stratified by HBeAg status, adjusted for age, sex, and the 4 ancestry components identified PRELID2 rs371991 (B= −0.74, standard error [SE] = 0.16, P = 3.44 ×10–6) for HBeAg-positive patients. Importantly, PRELID2 was cross-validated for long-term response in HBeAg-negative patients. G3BP2 rs3821977 (B = 1.13, SE = 0.24, P = 2.46 × 10–6) was associated with response in HBeAg-negative patients. G3BP2 has a role in the interferon pathway and was further examined in peripheral blood mononuclear cells of healthy controls stimulated with IFNα and TLR8. After stimulation, less production of IP-10 and interleukin (IL)-10 proteins and more production of IL-8 were observed with the G3BP2 G-allele.ConclusionsAlthough no genome-wide significant hits were found, the current GWAS identified genetic variants associated with (Peg)IFN response in CHB. The current findings could pave the way for gene polymorphism-guided clinical counseling, both in the setting of (Peg)IFN and the natural history, and possibly for new immune-modulating therapies.Clinical Trials RegistationNCT01401400.
