About 75% of liver cancers are attributed to chronic hepatitis B (CHB). An estimated 2.2 million individuals in the U.S. have CHB. Although Asian Americans make up 6% of total U.S. population, they account for over 58% of Americans with CHB. Prevalence rates of CHB range from 8% to 13% in Asian Americans vs 1% in Non-Hispanic whites (NHW). Asian Americans are 8-13 times more likely to develop liver cancer with 60% higher death rate than NHW. Regular monitoring of CHB is vital in preventing HCC. Research indicates that regular monitoring (e.g., every six months doctor visit; blood tests) combined with antiviral treatment when appropriate, is critical to reduce the risk of liver disease (including HCC). Unfortunately, treatment effectiveness diminishes if CHB patients do not adhere to long-term monitoring and treatment guidelines. Adherence among Asian Americans with CHB is low. Poor healthcare access and significant cultural barriers prevent long-term adherence to monitoring and optimal treatment, placing Asian Americans at disproportionately high risk for HCC and increased healthcare costs. Building on previous studies, the investigators will use a virtual patient navigation (VPN) toolkit system (a web/mobile application) to help CHB patients improving their liver disease management.
The objective of this study is to identify immunological mechanisms that contribute to normalization of liver inflammation in chronic hepatitis B (CHB) patients starting the antiviral nucleoside analogue, Tenofovir alafenamide (TAF).
Entecavir 1 mg is commonly used in patients with chronic hepatitis B (CHB) patients with previous antiviral resistance. This study evaluates the efficacy and safety of switching to generic entecavir 1 mg (Baracle®, Dong-A Science Technology) in CHB patients taking brand name entecavir 1 mg (Baraclude®, Bristol-Myers Squibb) alone or in combination with other nucleos(t)ide analogues after the development of antiviral resistance. The primary aim is virological response (<20 IU/mL) at 12 months
An open-label, Phase 2, exploratory study to examine the safety and efficacy of inarigivir in non-cirrhotic, hepatitis B treatment-naive subjects with chronic HBV infection.
Chronic hepatitis B is a global public health problem, with nearly 700,000 deaths each year because of hepatitis B-related diseases. Recent studies have found that some patients who have used nucleot(s)ide analogues(NAs) for some period can achieve higher hepatitis B surface antigen(HBsAg) clearance rate(which is called clinical cure or functional cure) by using pegylated interferon. Patients who achieve clinical cure will further reduce liver inflammation, fibrosis and risks of liver cirrhosis and cancer in the future. This study was initiated in May 2018 and plans to recruit 30,000 eligible patients. The enrollment conditions are as follows: 1. according with the diagnosis of chronic hepatitis B in the guideline of China in 2015; 2.18-60 years old; 3. more than 1 year history of NAs therapy with HBsAg ≤1500 IU/ml, negative hepatitis e antigen and hepatitis B virus DNA<100 IU/ml; 4. no contraindications of interferon. For the above patients, pegylated interferon was used for 1-2 years(combined with NAs for at least 3 months).The primary goal of this study is to find out the optimal treatment for clinical cure.

Explore the relevance of effective diagnosis of liver changes. To explore the characteristics of clinical indicators that can effectively diagnose liver histopathological changes, and to provide clinical indicators for patients with chronic hepatitis B to receive timely treatment of histopathological changes, and provide important evidence for patients with chronic hepatitis B to receive timely treatment.
All chronic hepatitis B (CHB) patients were diagnosed and treated in the liver disease department of the Hepatology Center of Beijing Ditan Hospital affiliated to Capital Medical University and those who received antiviral therapy (interferon and nucleoside analogues) reached HBsAg<100 IU/ml. The enrolled subjects were divided into the following six observation cohorts: 1) CHB patients in the immunological control period, without any clinical treatment intervention; 2) After interferon therapy, HBsAg<100 IU/ml, continued interferon therapy; 3) After interferon therapy, HBsAg<100 IU/ml, stopped interferon treatment; 4) After interferon therapy, HBsAg<100 IU/ml, sequential nucleoside analog treatment; 5) After nucleoside analogue treatment, HBsAg<100 IU/ml, sequential interferon treatment; 6) After treated with nucleoside analogues, HBsAg<100 IU/ml, continuing the nucleoside analog treatment. The follow-up observation period was 96 weeks under non-planned intervention. During the observation period, HBV indicators and biochemical indicators, serum AFP and liver imaging (liver ultrasound) were examined regularly. The main evaluation index was the incidence of HBsAg disappearance during the observation period. Secondary evaluation indicators: the rate of HBV DNA turning positive, the rate of HBeAg turning positive and hepatitis incidence. To observe the inactive carrier status of low HBsAg content and the incidence of HBsAg disappearance, clinical outcomes and influencing factors in patients with CHB under different antiviral interventions.
This study was a retrospective clinical observational cohort study. All patients with chronic hepatitis B (CHB) whose HBsAg decreased by less than 10% were treated continuously with interferon in the Department of Hepatology, Beijing Ditan Hospital, Beijing Medical University, Beijing Capital University, 2008.10-2017.4. The total interferon treatment time of the enrolled subjects was 48 weeks. The subjects were randomly divided into the following two observation cohorts: 1) patients with chronic hepatitis B treated with continuous interferon for 48 weeks; 2) intermittent interferon For 48 weeks of treatment for patients with chronic hepatitis B, the interferon treatment interval was 3 months. HBV DNA content, HBsAg/anti-HBs, HBeAg/anti-HBe and biochemical markers, serum AFP and liver imaging (liver ultrasound) were collected before treatment (baseline) and during treatment. The primary outcome measure was the rate at which HBsAg disappeared at 48 weeks of treatment. The secondary evaluation index was the 48-week HBeAg seroconversion rate. To investigate the efficacy, influencing factors and safety of interferon intermittent treatment of chronic hepatitis B.
