Filter by:This study is a randomised, controlled, unblinded, clinical intervention trial consisting of 12 weeks of aerobic exercise training. Thirty persons with chronic hepatitis B (CHB) and hepatic steatosis are randomised to either aerobic exercise training (intervention group, n=15) or no intervention (control group, n=15). The study will investigate the effects of the exercise intervention on the liver and the hypothesis is that the exercise group will reduce the fat-fraction of the liver after the intervention.
The aim of study is to evaluate the current prevalence of HDV infection, and comprehensively analyze the interaction between HDV and HBV infections in the era of NAs in Taiwan. Investigators plan to set up a platform for HDV positive patients in Taiwan to invite sites or hepatologists who are interested in this field.
In the globe, about 33% (2 billion) of population has ever been infected with hepatitis B virus (HBV), and about 5% (350-400 million) were chronical HBV infection. In areas with high prevalence of hepatitis B, up to 80% of primary liver cancers are associated with HBV infection. About 25% of chronic hepatitis B virus carrier (more than 1 million people per year) eventually die of end stage liver disease associated with HBV infection, such as liver failure associated with cirrhosis and hepatocellular carcinoma. HBV replicates in the liver, which increases the risk of hepatocellular carcinoma in HBV carriers. Studies have shown that the risk of hepatocellular carcinoma (HCC) in HBV carriers was 10-100 folds higher than that of non-carriers. Clinically, there are primarily two types of antiviral drugs: α-interferons (plain and pegylated ([PEG-IFN]α-2a or α-2b) interferons) and nucleos(t)ide analogues (NUC) including lamivudine (LAM), adefovir dipivoxil (ADV), entecavir (ETV), telbivudine (LDT), tenofovir disoproxil fumarate(TDF) and tenofovir alafenamide fumarate(TAF). With the development and application of antiviral drugs in recent years, the basic goal of maintain suppression against virus replication has been achieved, and HBsAg loss is considered as function cure of antiviral therapy. However, data from clinical studies showed a very low cure rate of current antiviral drugs and a natural HBsAg loss usually is less than 3%. The vast majority of clinical patients require long-term antiviral treatment and have difficulties in treatment stop. The AI data mining system innovated by the Holy Haid owns a ten-million-scaled database and utilizes dozens of HBV-associated targets to identify 100 drugs that are most closely to the targets among the 500 commercially available drugs. With the identified 100 drugs, Holy Haid (Ying-ying Li) and Beijing Tsinghua Changgung Hospital (Lai Wei) conducted a cytological verification in mice, which indicated that the HD042 (Celecoxib) at 20uM concentration can inhibit HBV DNA, HBsAg and HBeAg by 70.87%, 88.52% and 87.55% respectively, without significant cytotoxicity. Based on this, Beijing Tsinghua Changgung Hospital (Lai Wei) retrospectively analyzed 1,114,661 patients admitted to 304 hospitals in 107 cities of 21 provinces and municipalities from January 1, 2019 to October 31, 2020 and identified 19,692 patients with the results of two HBsAg tests available and an interval of over 30 days. Among these, 3,359 patients had ever took HD042 (Celecoxib). Further analysis showed that these 3,359 patients, and screened out 383 patients who were diagnosed of hepatitis B and excluded from tumor with two HBsAg levels > 0.05IU/ml but ≤1500IU/ml. Among these, 110 patients were prescribed for more than 5 Celecoxib doses (about 30 days of treatment). Among the 110 patients, we screened out 27 patients on Celecoxib for 12 weeks whose HBsAg expression decreased by 59.2% after 12 weeks, including HBsAg clearance rate (i.e., HBsAg decreased to < 0.05IU/ mL) up to 18.5%. Celecoxib, a specific inhibitor of Cyclooxygenase 2 (COX-2), has been widely used in clinical practice as an anti-inflammatory and analgesic drug. Studies have shown that Celecoxib improves NASH by inhibiting inflammatory responses. In addition, some studies have also shown that COX-2 is highly expressed in hepatitis B related hepatocellular carcinoma, resulting in cancerous tissue microangiogenesis. Cytological test found that Celecoxib, as a COX-2 specific inhibitor, can inhibit the growth of liver cancer cells by induced apoptosis and cell cycle inhibition, and have a even stronger effect on HBsAg positive liver cancer cells. However, the inhibitory effect of Celecoxib on the hepatitis B surface antigen in patients with chronic hepatitis B remained controversial. Therefore, this study is designed to investigate the safety and efficacy of Celecoxib in the hepatitis B surface antigen loss and reduction in nucleoside-treated patients with chronic hepatitis B.
This study aims to explore whether there is difference in the incidence rate and incidence rate of HCC in patients with chronic hepatitis B who are screened for high risk of liver cancer. Whether the timely intervention can be used to reduce the incidence of HCC for the early screening and early warning patients can provide evidence-based medical evidence for the selection or adjustment of anti HBV drugs in high-risk patients with liver cancer. To provide evidence for whether patients with liver nodules at high risk of liver cancer need to deal with liver nodules in advance.
This is a prospective/retrospective, observational follow-up study of effects of fatty liver on chronic hepatitis B. Patients will join this study who undergo transient elastography with liver stiffness (LS) and CAP measurements or Ultrasonic examination. All recruited subjects will undergo comprehensive clinical, anthropometric and laboratory assessments at the time when transient elastography or Ultrasonic examination is performed. We plan to compare the relationship between chronic hepatitis B and non-alcoholic fatty liver disease. Patients will be divided into several groups based on the demand.
The study is designed to assess efficacy of a finitie treatment in Chronic Hepatitis B patients who had stable treatment of NAs for ≧ 2 years， which is compared hepalatide in combination with Pegylated Interferon + TAF with Pegylated Interferon +TAF. Subjects will be randomly assigned to the hepalatide or placebo groups , 15 subjects in each group . Subjects will receive hepalatide+Pegylated Interferon +TAF treatment for 48 weeks or placebo +PegylatedInterferon +TAF treatment for 48 weeks , Then, stopping all treatments and followed with further 24 weeks follow-up.
The purpose of the study is to characterize the pharmacokinetic (PK) profile of cetrelimab administered subcutaneous (SC) and optionally intravenous (IV) in chronic hepatitis B (CHB) participants.
This is a randomized, double-blinded, placebo-controlled, multi center, dose ranging study of safety and efficacy in volunteers with chronic hepatitis B virus infection. Volunteers will be administered multiple oral doses of ATI-2173 vebicorvir in combination with tenofovir disoproxil fumarate and assessed for safety and efficacy including blood tests to show how the body metabolizes and eliminates the investigational drug as well as how the drug effects the virus infection.
The purpose of study is identifying the effectiveness of 'continuing medical education' (CME) to primary healthcare worker to improve knowledge about viral hepatitis B-C
To date, antiviral treatment is not recommended for chronic hepatitis B patients with a normal ALT level and low viremia. The strategy is to closely monitor the patients. However, evidence suggests that these group are at risk of gradual disease progression and development of hepatocellular carcinoma. Peginterferon eliminates the hepatitis B virus through immune regulation and induction of antiviral protein expression. For patients with low viral load, the clinical cure rate is potentially promising. In this study, we aim to investigate the efficacy and safety of peginterferon alpha-2b therapy in selected chronic hepatitis B patients with normal ALT level and low viremia. It is expected to obtain a satisfactory curative effect. Peginterferon is a marketed drug available in Chinese clinics with indications of anti-hepatitis B virus.
