Filter by:Hepatitis B virus (HBV) infection is a major public health threat in China. At present, a functional cure, also known as clinical cure or sustained Hepatitis B surface antigen (HBsAg) loss, is recommended as the ideal endpoint of HBV treatment. However, HBsAg loss can be achieved in less than 10% of chronic hepatitis B (CHB) patients treated with current available antiviral drug interferon (IFNα) or nucleos(t)ide analogues (NAs) monotherapy. With the support of the national major special funding for infectious diseases from "11th Five-Year Plan" to "13th Five-Year Plan", we have implemented a pioneer clinical study of sequential combination of IFNα therapy on NAs to treat NAs-treated CHB patients (ie. New Switch Study). This is the world's first clinical trial aiming to functional cure, which increased the rate of HBsAg loss to 15% in the overall population in our study, and to 30-50% among those with lower baseline HBsAg levels. How to further improve the HBsAg loss rate is an urgent issue for us. The key point of achieving functional cure is to reverse the HBV-specific T cell exhaustion and establish the long-term immune control against HBV infection. (Programmed death-1) PD-1/programmed death-ligand 1 (PD-L1) axis blockade has been demonstrated to reinvigorate exhausted CD8+ T cells, and would be a potential strategy to treat chronic HBV infection. In this study, a large multicenter prospective study will be performed to explore the safety and efficacy of a novel combination strategy involving immune checkpoint inhibitor (anti-PD-1 antibody) and IFNα in CHB patients, observe the HBsAg loss rate in NA-treated CHB patients receiving this combination strategy, evaluate the potential of breaking immune tolerance by this strategy, and further assess its efficacy to further improve the clinical cure rate on the basis of New Switch Study. Based on New Switch Study, this study further attempts to reverse T cell exhaustion in CHB patients, explore a novel platform of combination therapy development for clinical cure, and ultimately increase the HBsAg loss rate to higher than 50% in overall patients. The implementation of the project is expected to reduce the burden of HBV infection in China and contribute to the goal of global elimination of hepatitis B and C by 2030 (WHO 2030).

Osteoporosis is a condition that describes compromised skeletal microarchitecture in general, with clinical signs of decreased bone mineral density. Patients with hepatitis c virus infection are at increased risk for developing osteoporosis. Identifying whether patients with hepatitis c virus infection have information and awareness about this disease is crucial. This study is aimed to investigate awareness and knowledge of osteoporosis in patients with hepatitis c virus infection.
Osteoporosis is a condition that describes compromised skeletal microarchitecture in general, with clinical signs of decreased bone mineral density. Patients with hepatitis b virus infection are at increased risk for developing osteoporosis. Identifying whether patients with hepatitis b virus infection have information and awareness about this disease is crucial. This study is aimed to investigate awareness and knowledge of osteoporosis in patients with hepatitis b virus infection.
Chronic hepatitis B (CHB) affects an estimated 292 million people, and causes approximately 800,000 people deaths per year from liver-related complications including cirrhosis and hepatocellular carcinoma, remaining a major global public health issue.Meanwhile, the rising incidence of metabolic syndrome (MetS) is another grim health burden. Combined MetS affects the metabolic function of hepatocytes, which are responsible for providing HBV replication. Antiviral therapy is an effective measure to reduce the risk of cirrhosis and liver cancer in patients with chronic CHB. Combined MetS may affect the antiviral efficacy in patients with CHB.This prospective observational study examines the differences in HBeAg serological conversion rates between HBeAg-positive CHB patients with and without MS who received first-line oral antivirals for 144 weeks.
To Demonstrate Clinical Performance of the TriQuik Invitro Diagnostic Device
During the Covid-19 pandemic era, patients indicated that they find a model of care incorporating remote consultations to be acceptable [1-3]. Remote accessibility to care can be enhanced by using new technology to allow small volume testing for routine blood samples. This study aims to prospectively validate the use of small volume blood sampling for routine HIV-1 and Hepatitis B Virus (HBV) viral load (VL), liver function tests (LFTs) and creatinine, and assess the acceptability of this method of blood sampling to people living with HIV (PLWH). These tests form the usual minimum required for safe monitoring on a routine basis to determine viral activity, liver and renal function in patients either on or off antiviral therapy. The UK based Doctors Laboratory TINIES small volume blood testing kits comprise microcontainers manufactured by BD Diagnostics designed for sample collection from skin puncture, along with home testing pack with lancets, instructions and Royal Mail postal packs. We will collect TINIES samples alongside routine venepuncture samples in people attending their routine clinic follow ups. We will then send kits to different participants to collect samples in their own home, along with a follow up questionnaire (written/online). Finally, we will conduct a more in-depth telephone interview for a subset of patients to qualitatively assess acceptability. Routine use of this method of testing could revolutionise care of people living with chronic blood borne viruses, for example HIV and chronic HBV. TINIES could enable remote monitoring, increasing ease of access to care, reducing clinic appointment burden in otherwise healthy individuals, and reduce labour costs in the NHS, for example, by reducing phlebotomy appointments.
The purpose of this study is to evaluate immunogenicity and safety of inactivated hepatitis A vaccine in healthy children aged from 24 months to 15 years when administered an initial dose followed by a booster dose (a total of 2 doses administered with 6 months interval).
Substance users are a vulnerable group that should be prioritized in HCV (Hepatitis C Virus) elimination efforts in Mexico and in which it is feasible to carry out micro-elimination programs. It is an important group to treat both because of its high prevalence and because of the dynamic spread of infection among the general population. HCV seropositivity has not been documented in this group of people in Mexico City, the metropolitan area and the northern states of the country, nor has the sustained viral response been evaluated in this group of patients in the Mexican population.
The study is aimed to explore the safety and efficacy of the pulse usage , comparing to continuous usage, of Peginterferon alfa-2b Injection (PEG IFN α-2b) Combined With tenofovir alafenamide (TAF) in treatment of naive chronic hepatitis B patients with HBeAg negative.
