Objective: This study aimed to investigate whether cytokine profiles and virological markers might add value in monitoring the effects of peginterferon (PEG-IFN) therapy for hepatitis B e-antigen (HBeAg) positive chronic hepatitis B (CHB). Methods: HBeAg positive patients with CHB were treated with PEG-IFN for 48 weeks. Clinical biochemical, and HBV serological indexes, as well as cytokines, were detected at baseline and every 12 weeks. Results: A total of 116 patients with CHB were enrolled in this study; 100 patients completed the 48-week treatment and follow-up, of whom 38 achieved serum HBeAg disappearance, 25 achieved HBeAg seroconversion, 37 showed HBsAg decreases ≥ 1 log ₁₀ IU/mL, 9 showed HBsAg disappearance, and 8 became HBsAb positive. The cytokine levels at baseline and during treatment were similar between the HBeAg disappearance group and non-disappearance group. The disappearance of HBeAg was independently associated with HBeAg levels at weeks 12 and 24, and with the HBeAg decline at week 24 ( P < 0.05). The HBsAg response was independently associated with HBsAg, the HBsAg decline, HBeAg, the HBeAg decline at week 12, and HBsAg at week 24 ( P< 0.05). Conclusion There was no significant correlation between the response to interferon (IFN) and cytokines during PEG-IFN treatment. The changes in virological markers predicted the response to IFN after 48 weeks.

Objective:b> To explore the clinical significance of hepatitis B pregenomic RNA (pgRNA) for deciding antiviral therapy discontinuation in patients with chronic hepatitis B (CHB). Methods:b> Data of patients with CHB who were treated with long-term antiviral therapy in the Center for Infectious Diseases, West China Hospital of Sichuan University from January 2019 to December 2019 were collected. Drug discontinuity after evaluation of high-sensitivity HBV DNA and HBV pgRNA (HBV DNA ≤20 IU/ml and HBV pgRNA<150 copies/ml) was observed. The prospective observational study on 91 patients with HBeAg-negative CHB was conducted. The clinical conditions were followed up 3, 6 and 12 months after the drug discontinuation. The relationship between HBV pgRNA and relapse after drug discontinuation was analyzed. Results:b> From observation to 12 months after drug discontinuation, a total of 34 patients (37.4%) had developed recurrence and resumed antiviral therapy, and the cumulative recurrence rate within 12 months of drug discontinuation was 46.8%. Among the relapsed patients, 14 (41.2%) had biochemical breakthroughs, and all achieved good biochemical and virological responses after the resumption of antiviral therapy. The Cox multivariate proportional hazards regression analysis showed that the level of HBV pgRNA before drug discontinuation and the type of antiviral drugs taken were associated with recurrence after drug discontinuation. The risk of recurrence after drug withdrawal in the HBV pgRNA ≤50 copies/ml group was 2.316 times higher than that in the HBV pgRNA negative group (HR=2.316, 95%CI: 1.047-5.126, P=0.038). The risk of recurrence after drug withdrawal in the HBV pgRNA >50 copies/ml group was 3.45 times higher than that in the HBV pgRNA negative group (HR=3.450, 95%CI: 1.338-8.892, P=0.010). Conclusion:b> HBV pgRNA can be used to predict the risk of recurrence after antiviral therapy discontinuation in patients with CHB. Patients with negative serum HBV pgRNA before drug discontinuation have a relatively low risk of relapse after drug discontinuation, and drug discontinuation is not recommended for patients with HBV pgRNA >50 copies/ml.

BACKGROUND: Hepatitis B core-related antigen (HBcrAg) is a promising disease-monitoring marker for chronic hepatitis B (CHB). We investigated correlations between HBcrAg with antiviral efficacy and virological and histological variables. METHODS: One hundred and forty-five CHB patients from the mainland of China between August 2013 and September 2016 who underwent liver biopsy received entecavir therapy and had paired liver biopsy at 78 weeks. We analyzed correlations between HBcrAg and virological and histological variables in hepatitis B e antigen (HBeAg)-positive and HBeAg-negative patients. We also explored the predictors of HBeAg loss after 78 weeks of antiviral therapy. Pearson correlation analysis and logistic forward stepwise regression were the main statistic methods. RESULTS: HBeAg-positive patients (n = 93) had higher baseline HBcrAg (median 7.4 vs. 5.3 log10 U/mL P < 0.001) and greater HBcrAg declines (median 1.6 vs. 0.9 log10 U/mL P = 0.007) than HBeAg-negative patients after 78 weeks of therapy. At baseline, HBcrAg correlated with hepatitis B virus (HBV) DNA in both HBeAg-positive (r = 0.641, P < 0.001) and -negative patients (r = 0.616, P < 0.001), with hepatitis B surface antigen (HBsAg) in HBeAg-positive patients (r = 0.495, P < 0.001), but not with anti-hepatitis B virus core antibody (anti-HBc). Weak correlations existed between HBcrAg, histology activity index (HAI; r = 0.232, P = 0.025), and Ishak fibrosis score (r = -0.292, P = 0.005) in HBeAg-positive patients. At 78 weeks, significant correlations existed only between HBcrAg and anti-HBc in HBeAg-positive (r = -0.263, P = 0.014) and HBeAg-negative patients (r = -0.291, P = 0.045). Decreased HBcrAg significantly correlated with reduced HBV DNA (r = 0.366, P = 0.001; r = 0.626, P < 0.001) and HBsAg (r = 0.526, P = 0.001; r = 0.289, P = 0.044) in HBeAg-positive and -negative patients, respectively, and with reduced HAI in HBeAg-positive patients (r = 0.329, P = 0.001). Patients with HBeAg loss (n = 29) showed a larger reduction in HBcrAg than those without (median 2.3 vs. 1.3 log10 U/mL, P = 0.001). In multivariate analysis, decreased HBcrAg was an independent predictor of HBeAg loss (P = 0.005). CONCLUSIONS: HBcrAg reflects viral replication and protein production. Decreased HBcrAg could predict HBeAg loss after antiviral therapy.

<b>OBJECTIVEb>To use a lectin microarray to study the alteration of glycan affinity profiles of serum glycoproteins during the hepatitis B e antigen (HBeAg) and hepatitis B surface antigen (HBsAg) seroconversion in patients with chronic hepatitis B (CHB) following treatment with antiviral therapy,and to explore its biological significance.

<b>METHODSb>CHB patients were divided into the following four groups:untreated HBeAg-positive,HBeAg seroconversion after anti-HBV therapy,HBsAg loss after anti-HBV therapy,and healthy individuals (controls).Serum samples were collected from each participant,depleted of high abundance proteins and analyzed by a lectin microarray containing 50 lectins.The lectin-affinity glycan profiles of serum proteins were partially verified by lectin blotting.Between-group differences were analyzed by one-way analysis of variance,and pairwise comparisons were carried out with the Student-Newman-Keuls (SNK) method.

<b>RESULTSb>The results from the lectin microarray and lectin blotting assay showed significantly reduced affinity for 16 lectins in the untreated HBeAg-positive group compared to the control group (P less than 0.05);in addition,the specific glycan profiles of the untreated HBeAg-positive group included decreased terminal and core fructose,GalNAc alpha-Thr/Ser (T,Tn-antigen),GalNac alpha,terminal beta1-4,and beta-D galactose,bisecting and/or GlcNAc,mannose and Sia.However,the HBeAg seroconversion after anti-HBV therapy group showed enhanced binding of PSA,MPL and the above-mentioned 16 lectins (P less than 0.05),suggesting that the reduced serum glycoprotein glycan structures returned to normal or slightly higher than healthy levels after the therapy-induced seroconversion.Comparison of the group with HBsAg loss after anti-HBV therapy to the group with HBeAg seroconversion after anti-HBV therapy showed the binding ability of ten lectins (AAL,ACL,HAL,HPL,RCA-I,LEL,STL,PHA-E,NML and PCL) were weakened to near control levels and six lectins (VAL,LCA,GNL,PSA,MPL and JAC) were significantly strengthened (all P less than 0.05). These findings implied that the glycan containing terminal fructose, GalNacalpha, terminal beta1-4 galactose,and bisecting GlcNAc glycan structures dropped to near control levels, while the terminal beta-D-galactose residues and core fructose structure increased significantly.

<b>CONCLUSIONb>The glycan structures of serum glycoproteins are closely related to HBeAg and HBsAg seroconversion in CHB patients.It is possible that a special lectin binding glycan involving the terminal beta-D-galactose residues and core fructose may act as sugar markers associated with the disappearance of serum HBsAg during anti-HBV therapy for CHB.

The infection of Hepatitis B virus (HBV) can result in severe consequences, including chronic hepatitis, liver fibrosis, cirrhosis, and even liver cancer. Effective antiviral treatment has the potential to slow down the progression of the disease. HBV serum biomarkers play a crucial role in the dynamic management of chronic hepatitis B (CHB) patients. However, the conventional hepatitis B virus markers, such as hepatitis B serologic testing and HBV DNA, are insufficient to meet the clinical requirements. This review provided a comprehensive overview of the current research on the quantification of HBsAg and anti-HBc, HBV RNA and HBV core-associated antigen, which summarized the crucial role these markers play in the administration of antiviral medications, predicting the efficacy of treatment and anticipating the likelihood of virologic rebound following drug cessation, as well as assessing disease progression in CHB patients.

Objective:b> To investigate the effectiveness of nucleos(t)ide analogues in the treatment of HBeAg-positive chronic hepatitis B with normal alanine aminotransferase and high level of HBV DNA. Methods:b> Treatment-naïve chronic hepatitis B patients who were followed up at the Center of Infectious Diseases, West China Hospital of Sichuan University from January 2019 to January 2020 were selected as subjects. Demographic characteristics, the results of laboratory examination before treatment and one year after treatment were retrospectively collected. Patients were divided into tenofovir dipivoxil (TDF) and propofol fumurate tenofovir (TAF) treatment group according to different types of medication. The changes of serum HBV DNA level, HBeAg serological conversion and HBsAg quantitative level were analyzed and compared between the two groups. Results:b> A total of 38 cases were enrolled. Among them, there were 16 and 22 cases in the TDF and TAF group, respectively. There was no statistically significant difference in demographic characteristics, baseline HBV DNA levels and HBsAg quantitative levels between the two groups. Virological response was achieved in 60.5% (23/38) of patients after one year of antiviral therapy. Serum HBV DNA levels below the lower limit of detection [68.2% (15/22) vs. 50.0% (8/16), P=0.258] and higher HBeAg seroconversion rate [18.2%] (4/22) vs. 6.3% (1/16), P=0.374] was obtained in TAF than TDF group; however, there was no statistically significant differences between the two. Serum HBsAg quantitative level was significantly reduced with TDF and TAF treatment. In addition, alanine aminotransferase elevation was reduced in TAF than TDF treated group. Multivariate logistic regression analysis showed that patient age was an independent predictor of a virological response to antiviral therapy. Conclusion:b> HBeAg-positive CHB patients with normal alanine aminotransferase, and high HBV DNA level can obtain better curative effect after TDF and TAF treatment.

<b>OBJECTIVEb>To compare the efficacy and safety of Stronger Neo-Minophagen C (SNMC) in the treatment of chronic hepatitis B.

<b>METHODSb>We searched MEDLINE, EMBASE, CBM, and CNKI up to December, 2012 to identify randomized controlled trials (RCTs) comparing Stronger Neo-Minophagen C plus other therapy versus others therapy for chronic hepatitis B. Two reviewers independently assessed the risk of bias and extracted data from the included RCTs according to the Cochrane Reviewers Handbook 5.1.0. Meta-analyses were performed using RevMan 5.1 software.

<b>RESULTSb>Thirty-one trials involving 2753 patients were included in the analysis. The results of meta-analyses showed that SNMC improved hepatic functions of the patients by reducing ALT (MD=-31.63, 95% CI: -51.57, -11.70), AST (MD=-18.70, 95% CI:-25.10, -12.30), TBIL (MD=-12.17, 95% CI: -17.63,-6.71), HA (MD=-94.89, 95% CI: -125.19, -64.60), LN (MD=-40.08, 95% CI: -52.38,-27.78), IV-C (MD=-50.61, 95% CI:-63.40, -37.81), PC-III (MD=-49.71, 95% CI: -71.72, -27.69) as compared with the control group. The seroconversion rate of HBeAg (OR=2.23, 95% CI: 1.70, 2.94), HBV-DNA (OR=2.20, 95% CI: 1.70, 2.84), HBsAg (OR=2.25, 95% CI: 1.24 , 4.07), total response rate (OR=4.37, 95% CI: 2.62, 7.28), and ALT normalization rate (OR=3.77, 95% CI: 2.46, 5.79) were all significantly higher in the combined therapy group than in the control group.

<b>CONCLUSIONb>SNMC plus other therapy is more effective than other therapy alone in improving the hepatic function and hepatic fibrosis and increasing hepatic seroconversion rate in patients with chronic hepatitis B without causing serious adverse events. But considering the low quality of the included studies, the results should be interpreted with caution and awaits further confirmation by high-quality, large-scale RCTs.
