Chronic Hepatitis B Virus Infection in Zambia

Chronic hepatitis B virus infection is a common condition in Zambia. Among Zambian blood donors, up to 8% are chronically infected with HBV. Despite the burden, awareness of HBV is low in Zambia and the Ministry of Health is in early stages of development of guidelines for HBV screening, treatment, and prevention. The purpose of this clinical cohort study is to characterize the clinical features of chronic HBV infection at UTH and describe treatment and care outcomes. The investigators will enroll 500 adults and follow the cohort for up to 5 years to assess short and long-term viral, serologic, and liver outcomes such as cirrhosis and liver cancer.

The Impact of Tenofovir Alafenamide on Profiles of Body Weight and Metabolic Features in Chronic Hepatitis B Patients.

The aim of this study is to compare the BW and metabolic profiles of CHB patient before and after shifting to TAF therapy. In this study, investigators will enroll 100 entecavir and 100 TDF treated CHB patients who will switch to TAF and then follow for one year. Demographic, liver function tests, sugar profiles, lipid profiles, ASCVD risk score, body weight, body weight, body height, and waist circumference will be checked and recorded periodically. Investigators anticipated that body weight will change significantly after switching to TAF in both entecavir and TDF group and may associated with increased risk of cardiovascular risk.

Specific Anti-HBV Vaccine Response After Vaccination in Patients Requiring Anti-CD20 Monoclonal Antibodies

Vaccination coverage against HBV in France is around 30% in the adult population. Treatment with anti-CD20 is associated with a risk of reactivation of hepatitis B or acute or fulminant hepatitis in first-infected patients. HBV vaccination is recommended as before any anti-CD20 treatment in unimmunized patients. However, there is no recommendation on which vaccination regimen to choose in patients on immunosuppressants / corticosteroids or with inflammatory or autoimmune disease. For patients who have a need for rapid immunosuppressive therapy, the use of a standard vaccination schedule (D0, M1, M6) would be responsible for a loss of chance vis-à-vis the underlying disease with a delay of more than 6 months to start treatment with anti-CD20. An accelerated regimen (D0, D7, D21 and M12) allows healthy adults to obtain very rapid vaccine protection between 77 and 90.8%. The accelerated regimen can also be considered on a case-by-case basis in those adults with neurological pathologies, systemic vasculitis or autoimmune disease and who need to receive anti-CD20 antibodies if the combination of injections over a short period is likely to promote immunization. The advantage of the accelerated regimen is to obtain 4 weeks, after the third dose of vaccine, anti-HBs antibodies at a protective level (> 10 IU / L) in approximately 77 to 90.8% of patients and in the general population. The booster injection at 12 months is essential for long-term protection.

Tenofovir Alafenamide for HBV Prophylaxis in HBV(-) Liver Transplant Recipients With HBcAb+ Donors

Liver transplantation is currently the only effective way to treat end-stage liver disease.The shortage of donor liver is still the major problem. Incidence of HBcAb+ varies between different regions. The HBcAb positive rate could be as high as 52% in China.HBcAb positive donor liver may enlarge donor pool and thus save ESLD patients. However, the use of HBcAb positive donor liver may induce HBV infection in hepatitis B negative recipient after liver transplantation. Tenofovir alafenamide (TAF) has better stability in plasma and higher liver targeting property in comparison with tenofovir (TDF), with an extra amide bond, which allows strong antiviral effect with much less doses and reducing the renal and bone injury. Our study intends to evaluate the efficacy and safety of HBV prophylaxis treatment of TAF in HBV negative patients after receiving HBcAb positive donor livers.

Tenofovir Alafenamide in HBV Related Decompensated Liver

TAF is a new prodrug of tenofovir, specifically designed to achieve higher intracellular active drug concentration allowing for dosing of only 25 mg once daily and thus can potentially lower the already relatively low risk of renal toxicity and bone loss with TDF. However, such renal and bone complications with TDF may become more pronounced in decompensated CHB patients10. In the phase 3 trials11, 12, TAF had demonstrated a compatible antiviral effect (noninferior efficacy), and a higher rate of alanine aminotransferase (ALT) normalization to TDF. TAF also demonstrated an improved renal function and less bone loss compared to TDF. Therefore, TAF was approved as the first line therapy for CHB patients with compensated liver function. The lack of data regarding TAF therapy in decompensated CHB patients raised the concern of safety and efficacy of TAF in this group of patients. A small, single arm Phase 2 switch study (GS-US-320-4035; Study 4035; NCT03180619) which has enrolled 31 subjects with CPT scores ?7, either at time of screening or by history, who were virally suppressed on TDF and/or other oral antiviral agents is currently underway with favorable safety and efficacy results through 48 weeks.[Lim YS, Lin CY, Heo J, et al. EASL 2020, poster SAT442.] While Gilead Study 4035 will continue through 96 weeks of treatment, additional data in this population are thus needed, particularly in CHB patients who have decompensated liver disease and are not being treated and are viremic. Herein, we conduct the present study and aim to investigate the safety and efficacy of TAF in CHB patients with hepatic decompensation.

A Pilot Study Comparing the Immunogenicity of Fendrix vs. Double-dose Engerix B in HIV-infected Non-responders to Standard Hepatitis B Vaccination Courses

Hepatitis B virus (HBV) infection can result in a greater risk of adverse outcomes in HIV-infected individuals, including more rapid progression to cirrhosis and associated complications such as hepatocellular carcinoma. For this reason, as well as the shared routes of transmission between the two viruses, UK and International guidance recommends that all HBV-negative HIV-infected individuals be offered vaccination against HBV. Unfortunately, response rates in this population can be as low as 17.5 - 40% to standard vaccination courses. To improve this response, strategies such as the use of double dose of standard vaccines (e.g. Engerix B) is recommended in several guidelines for previous non-responders, although there is currently limited evidence for this approach. An alternative strategy is to use vaccines with novel adjuvants such as Fendrix and observational clinical data in the Investigators HIV cohort suggests that response rates can be as high as 81% of individuals achieving HBV surface antibody (HBsAb) levels >100 in a group that did not respond to previous standard HBV vaccine courses. However, the cost of Fendrix is considerably higher than Engerix B and controlled trials are required to confirm whether this approach is warranted. Furthermore, insights into the potential mechanisms by which Fendrix may elicit better responses would be valuable in optimising future vaccine strategies in this population. The Investigators propose to conduct a randomised, open label, active-controlled pilot study comparing double dose Engerix B and Fendrix in HIV-infected non-responders to standard HBV vaccine courses, which will provide the necessary data to design and power a larger multicentre randomised controlled trial. Outcome measures will include the proportion of individuals seroconverting with HBsAb levels >100 following each vaccination course, the magnitude and quality of the HBV-specific CD4+ T-cell responses elicited by each vaccine and the durability of the HBsAb response at 1 year following the end of vaccination.

Entecavir and Tenofovir Versus Entecavir in Lymphoma Patients With Positive HBV DNA

This is a prospective, single-center, open-label, randomized controlled trial aimed to evaluate the efficacy and safety of entecavir and tenofovir versus entecavir alone in the antiviral treatment of HBV DNA positive B-cell lymphoma patients. This study plans to enroll about 120 participants in total. Recruitment will last for 2 years. The study visit will take place on the first day of each cycle of therapy until the end of the treatment. Participants who meet the inclusion/exclusion criteria were randomly assigned to receive entecavir and tenofovir or entecavir alone after signing the informed consent. HBV DNA will be measured before each cycle of chemotherapy or immunotherapy. When the copy count of HBV DNA drops below 1*10^3/L, entecavir single agent will be given orally, until one year after the cycle of therapy. Treatment response will be evaluated routinely after chemotherapy or immunotherapy. Within 2 years after the last participant is enrolled, participants' survival information will collected by telephone and/or clinical visit every 3 months after the last visit (i.e. date and cause of death, subsequent cancer treatment, etc.), if there is no withdrawal of the informed consent form.

Mechanism of DCs Dysfunction in Chronic HBV Infection

This research is to better understand the functional impairments of Dendritic cells (DCs) in chronic HBV infection. Aim is to determine if the virus is able to bind to the C-type lectin receptor (CLRs) of DCs to modulate their functions, also, to define the role of viral components and the molecular mechanisms of DCs modulation by HBV. This project should provide a better understanding of the mechanisms by which the immune response is altered by HBV and the immunological control of the infection, and thus propose new immunotherapeutic strategies based on the restoration of DC functions by releasing of virally-induced inhibitions, compromising the infection chronicity

Widespread vs. Selective Screening for Hepatitis B Infection Prior to Chemotherapy

This trial studies hepatitis B screening strategies of new cancer patients scheduled to undergo chemotherapy. Patients with cancer and hepatitis B virus infection are at risk of reactivation of infection after chemotherapy. Hepatitis B virus infection reactivation can be prevented by starting antivirals before chemotherapy in patients who are hepatitis B virus infection positive. Hepatitis B screening may help doctors prevent the reactivation of hepatitis B virus infection after chemotherapy.
