Virol J 2024; 21:77. [PMID: 38555445 PMCID: PMC10981809 DOI: 10.1186/s12985-024-02344-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Accepted: 03/17/2024] [Indexed: 04/02/2024] Open
Abstract
PURPOSE The purpose of this study was to investigate immunological variations between a group that received the hepatitis B vaccine and a non-vaccine group. We focused on a cohort that achieved HBsAg seroclearance after Peg-IFNα treatment of CHB. METHODS We enrolled twenty-eight individuals who achieved HBsAg seroclearance after Peg-IFNα treatment. They were divided into two groups: a vaccine group (n = 14) and a non-vaccine group (n = 14). We assessed lymphocyte subpopulations, B cell- and T cell-surface costimulatory/inhibitory factors, cytokines and immunoglobulin levels were detected at different time points to explore immune-function differences between both groups. RESULTS The seroconversion rate in the vaccine group at 24 weeks post-vaccination was 100%, which was significantly higher (p = 0.006) than that of the non-vaccine group (50%). Additionally, more individuals in the vaccine group exhibited anti-HBs levels exceeding 100 IUs/L and 300 IUs/L compared to the non-vaccine group (p < 0.05). The vaccine group demonstrated significantly increase total B cells and class-switched B cells at 24 weeks and plasma cells, CD80+B cells, Tfh cells, and ICOS+Tfh cell at 12 weeks, compared with baseline levels (p < 0.05). Conversely, Bregs (CD24+CD27+ and CD24+CD38high) decreased significantly at 24 weeks (p < 0.05). None of the above changes were statistically significance in the non-vaccine group (p > 0.05). Total IgG increased significantly in the vaccine group, and IL-2, IL-5, and IL-6 concentrations increased significantly at week 24 (p < 0.05). Differences in various types of cytokines and immunoglobulins in the plasma of the non-vaccine group were not significant (p > 0.05). Anti-HBs titers positively correlated with Th1/Th2 cells at 24 weeks (r = 0.448 and 0.458, respectively, p = 0.022 and 0.019, respectively), and negatively with CD24+CD38highBreg cells (r = -0.402, p = 0.042). CONCLUSIONS After achieving HBsAg seroclearance through Peg-IFNα treatment for CHB, administering the hepatitis B vaccine significantly increased anti-HBs-seroconversion rates and antibody levels. We also observed significant immunological differences between the vaccine and non-vaccine groups. Specifically, the vaccine group exhibited significant increases in B cells, plasma cells, and Tfh cells, while Breg levels was significantly lower. These immunological changes are likely conducive to the production of anti-HBs antibodies. However, in the non-vaccine group, the observed changes were not significantlly significant.

Braz J Infect Dis 2023; 27:103703. [PMID: 38036020 PMCID: PMC10698567 DOI: 10.1016/j.bjid.2023.103703] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2023] [Revised: 11/06/2023] [Accepted: 11/12/2023] [Indexed: 12/02/2023] Open
Abstract
Hepatitis B Surface Antigen (HBsAg) seroclearance is the highest treatment goal recommended by the current guidelines for hepatitis B. Levels of antibodies to HBsAg (anti-HBs) are strongly associated with HBsAg recurrence, but hepatitis B vaccination may increase the anti-HBs seroconversion rate and reduce recurrence. We conducted a retrospective clinical study to ascertain the effect of this vaccination on the seroconversion rate and levels of protective anti-HBs after HBsAg. In this retrospective study, we distributed a questionnaire through an online survey platform to collect information related to hepatitis B vaccination in patients with functional cure of hepatitis B with Interferon-α (IFNα) therapy. We enrolled 320 patients who achieved functional cure from IFNα therapy. Of these, 219 patients had received hepatitis B vaccination according to their personal preference and drug accessibility after HBsAg seroclearance, whereas the remaining 101 patients did not receive hepatitis B vaccination. The anti-HBs seroconversion rate of 78.1% in the vaccinated group was significantly greater than that in the unvaccinated group (41.6%) (p < 0.001). Stratified comparisons with anti-HBs of ≥ 100 IU/L and ≥ 300 IU/L showed that both proportions in the vaccinated group were greater than those in the unvaccinated group (71.2% vs. 32.7% and 56.2% vs. 17.8%, respectively, all p-values < 0.001). Logistic regression analysis showed that the odds ratio of vaccination was 4.427, which was the strongest influencing factor for anti-HBs, reaching 100 IU/L or higher. Hepatitis B vaccination in patients after HBsAg seroclearance not only increased the anti-HBs seroconversion rate but also significantly increased antibody levels, with good safety, indicating the clinical value of vaccine therapy for patients with functional cure.

Validation of Baveno VII criteria for recompensation in entecavir-treated patients with hepatitis B-related decompensated cirrhosis. J Hepatol 2022; 77:1564-1572. [PMID: 36038017 DOI: 10.1016/j.jhep.2022.07.037] [Citation(s) in RCA: 26] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 06/03/2022] [Accepted: 07/18/2022] [Indexed: 12/04/2022]
Abstract
BACKGROUND & AIMS Antiviral therapy improves the clinical outcomes of patients with chronic hepatitis B (CHB), including those with cirrhosis. In the present study, we validated the Baveno VII definition of recompensation and explored the criteria for stable improvement of liver function tests in entecavir-treated patients with CHB-related decompensated cirrhosis. METHODS In this multicentre prospective study, patients with decompensated (ascites) CHB-related cirrhosis were enrolled and treated with entecavir for 120 weeks. Patients were followed up for clinical events, viral and biochemical tests, and ultrasonography every 6 months. The recompensation rate per Baveno VII criteria was calculated. Multivariate regression models were used to identify the predictors of recompensation. Finally, the criteria for stable improvement of liver function tests were explored. RESULTS Of the 320 recruited patients, 283 completed the 120-week study, with 261/283 (92.2%) achieving HBV DNA levels <20 IU/ml and 171/283 (60.4%) achieving resolution of ascites, encephalopathy, and absence of recurrent variceal bleeding for at least 12 months. We identified model for end-stage liver disease <10 and/or liver function tests within Child-Pugh Class A (albumin >35 g/L, international normalised ratio <1.50 and total bilirubin <34 μmol/L) as the criteria for stable improvement of liver function tests. Accordingly, 56.2% (159/283) of patients fulfilled the Baveno VII definition of recompensation with a stable improvement of liver function tests defined by the current study. CONCLUSIONS Our study defined the criteria for a stable improvement of liver function tests required by the Baveno VII definition of recompensation in patients with CHB-related decompensated cirrhosis on antiviral therapy. The criteria derived from this multicentre prospective study warrant further validation in patients with cirrhosis of other aetiologies. LAY SUMMARY Decompensation of cirrhosis marks the point at which the liver is no longer able to function normally (and symptoms become apparent). Recently the idea of recompensation was proposed for individuals who may experience an improvement in liver function if the underlying cause of their liver disease is addressed (e.g. antivirals for viral cirrhosis). Herein, we show that over 50% of patients with hepatitis B-related decompensated cirrhosis treated with antivirals could recompensate and we propose laboratory criteria which could be used to define recompensation.

Study on the Retreatment, Outcome, and Potential Predictors of Recurrence in Patients With Recurrence of Hepatitis B After Functional Cure. Front Immunol 2022; 13:879835. [PMID: 35860247 PMCID: PMC9289245 DOI: 10.3389/fimmu.2022.879835] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2022] [Accepted: 05/31/2022] [Indexed: 11/17/2022] Open
Abstract
Background Studies about the retreatment and predictors for patients with hepatitis B recurrence after functional cure are rare. This study aimed to evaluate the effect of retreatment, outcome, and potential predictors of recurrence in patients with recurrence after functional cure. Methods A long-term follow-up was conducted with 32 cumulatively obtained patients who relapsed after cessation of pegylated interferon (Peg-IFN)-based antiviral treatment. The decision of whether to treatment or which therapeutic method to use [Peg-IFN or nucleos(t)ide analogs (NAs)] was based on the patient’s preferences and wishes. The rate of achieving functional cure and the clinical outcomes of different therapeutic methods were analyzed. Hepatitis B surface antibody (anti-HBs) and hepatitis B core antibody (anti-HBc) levels were detected in patients with blood samples during follow-up to evaluate the predictive ability of recurrence. Results The follow-up time of 32 recurrence cases was 42–532 weeks after recurrence (median 226 weeks). In the 20 patients who received retreatment (15 received Peg-IFN and 5 received NAs only), the rate of functional cure was 65.0% (13/20); it was 86.7% (13/15) in the patients retreated with Peg-IFN. Three cases experienced recurrence again. Five patients received NA treatment, and no functional cure was achieved. No drug intervention was administered for 12 patients, 2 of them with hepatitis B virus (HBV) DNA spontaneous clearance, and one patient achieved spontaneous hepatitis B surface antigen (HBsAg) clearance during follow-up. Patients who relapsed after functional cure with Peg-IFN treatment did not have liver cirrhosis or hepatocellular carcinoma during the follow-up, regardless of whether they received retreatment. Anti-HBs and anti-HBc levels at the end of therapy were predictors of recurrence (p < 0.001, p = 0.023). The value of combining the above two indicators in predicting recurrence was further improved, the areas under the receiver operating characteristic curves were 0.833, at combining predictors >-0.386, the predictive sensitivity and specificity for recurrence were 86.67% and 90.62%. Conclusion The functional cure rate was above 80% for patients with recurrence treated by Peg-IFN. During the follow-up, liver cirrhosis and hepatocellular carcinoma were not observed in all recurrence cases. High levels of anti-HBs and anti-HBc at the time of drug discontinuation are less likely to relapse.

Abstract
INTRODUCTION The current clinical guidelines do not recommend antiviral therapy for subjects with positive hepatitis B virus (HBV)-DNA and normal alanine transaminase (ALT). In this study, we will assess the safety and efficacy of tenofovir alafenamide fumarate (TAF) in the treatment of adults with positive HBV-DNA and normal ALT, including long-term prognosis. METHODS AND ANALYSIS This study is a non-double-blind randomised controlled trial. Study participants will be randomised into the treatment group and the control group. In the treatment group, subjects will receive TAF monotherapy, while those in the control group will receive no antiviral treatment. Subjects will be followed up at the beginning of the study and every 12 or 24 weeks thereafter for review of laboratory findings and to record adverse events. The primary endpoint is the proportion of patients with serum hepatitis B surface antigen loss. ETHICS AND DISSEMINATION This study protocol was approved by the Ethics Committee of the Third Affiliated Hospital of Sun Yat-Sen University for Human Study (reference number [2019]02-599-01). The results of this study will be submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER NCT04231565.

Abstract
Hepatitis B surface antigen (HBsAg) clearance is regarded as the ideal endpoint for antiviral treatment in terms of drug withdrawal safety and improvements in prognosis. However, the overall rate of HBsAg clearance is low and differs based on treatment method and course. The recent application of combined and extended treatment strategies have improved the HBsAg clearance rate, and several patients achieved HBsAg clearance in clinical treatment. In addition, the durability of and clinical outcomes after HBsAg clearance have become the focus of both researchers and clinicians. This article reviews HBsAg clearance in terms of accessibility, durability, improvements in prognosis and relevant advances.

Abstract
Diabetes mellitus (DM) is a common chronic disease affecting humans globally. During the last few years, the incidence of diabetes has increased and has received more attention. In addition to growing DM populations, DM complications are involving injuries to more organs, such as the heart and cerebral vessel damage. DM complications can reduce quality of life and shorten life spans and eventually also impede social and economic development. Therefore, effective measures to curb the occurrence and development of diabetes assist in improving patients' quality of life, delay the progression of DM in the population, and ease a social burden. The liver is regarded as an important link in the management and control of DM, including the alleviation of glucose metabolism and lipid metabolism and others via glucose storage and endogenous glucose generation from glycogen stored in the liver. Liver cirrhosis is a very common chronic disease, which often lowers the quality of life and decreases life expectancy. According to a growing body of research, diabetes shows a close correlation with hepatitis, liver cirrhosis, and liver cancer. Moreover, coexistence of liver complications would accelerate the deterioration of patients with diabetes. Liver cirrhosis and diabetes influence each other. Thus, in addition to pharmacological treatments and lifestyle interventions, effective control of cirrhosis might assist in a better management of diabetes. When it comes to different etiologies of liver cirrhosis, different therapeutic methods, such as antiviral treatment, may be more effective. Effective control of cirrhosis might be a strategy for better management of diabetes.
