Cohort Study of Clinical Outcomes in Chronic HBV Infection Patients With Low HBsAg Under Unplanned Intervention

Start date: May 1, 2017
Phase:
Study type: Observational

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.

NCT ID: NCT03587467 Recruiting - Healthy Clinical Trials

Study on Gut Microbiota in Chronic HBV Infected Patients

HBV
Start date: December 1, 2017
Phase:
Study type: Observational

Hepatitis B Virus(HBV) infection is a common infectious disease affecting up to 2 billion people worldwide. Around 650 thousand people died of liver failure, cirrhosis and primary liver cancer caused by chronic hepatitis B every year. Age is the main factor affecting the chronicity of hepatitis B, while 90% and 25% to 30% of hepatitis b virus(HBV) infection in perinatal and infant period will develop into chronic infection respectively. Whereas the proportion in patients above 5 years old is only 5% to 10%. Intestinal microbiota plays an important role in maintaining nomal physiological function of the intestine and the immune function of the body. It has been found that the disorder of intestinal microbiota is associated with numerous intestinal and parenteral diseases. Recently, the relationship between immune response and intestinal microbiota has been claimed. In a previous study using IMT to treat HBeAg positive chronic hepatits B patients combined with antiviral theraopy, 80% of them has reached HBeAg clearance. Increasing evidence suggests that the gut microbiota has evolved as a new important player in the pathogenesis of hepatitis B virus-induced chronic liver disease. However, the composition and structure alteration of the gut microbiota associated with the stage and progression of HBV infection remains unknown. Hence, we proposed a trial to detected gut microbiota of chronic HBV infected patients high-throughput 16S rRNA gene sequencing to elucidate the microbial influence which contribute to the microbial shift of patient in different stage.

NCT ID: NCT03329820 Completed - Clinical trials for Chronic Hepatitis B Infection

Quality of Life and Health Utility of Patients With CHB Infections

Start date: November 2006
Phase: N/A
Study type: Observational

The aim of the study is to assess the health-related quality of life (HRQOL) and preference-based health utilities of chronic hepatitis B (CHB) carriers in different stages of illness. It will also estimate the cost-effectiveness of anti-viral treatments resulting from the prevention of the progression of disease from uncomplicated CHB carriers to cirrhosis and hepatocellular carcinoma (HCC). The following hypotheses will be tested: 1. Patients with chronic hepatitis B virus (HBV) have poorer health-related quality of life (HRQOL) than the general population; 2. Patients with more severe stages of chronic HB infections have lower health related quality of life and health utility values; 3. Anti-viral treatment can improve the HRQOL and health utility for patients with CHB infections; 4. The cost-effectiveness of different treatments for chronic HBV infections can be directly compared in terms of cost/QALY gained.

NCT ID: NCT03210506 Recruiting - Clinical trials for Chronic Hepatitis B Infection

The Changes of Cytokines During Antiviral Therapy

Start date: January 2016
Phase: N/A
Study type: Interventional

Pegylated interferon α-2a(Peg-IFN-α) not only inhibit viral replication, but also play an important role in immune regulation, while Nucleoside analog(ue) drugs only inhibit viral replication. In hepatitis B infection, cytokines played a vital role. This study was aimed at investigating the changes of cytokines during Peg-IFN-αand nucleoside analog(ue) therapy.Meanwhile, the investigators wanted to verify whether Peg-IFN-α therapy resulted in the secretion of cytokines.

NCT ID: NCT03210493 Recruiting - Clinical trials for Chronic Hepatitis B Infection

The Changes of Treg Cells Frequency and Function During Antiviral Therapy

Start date: January 2016
Phase: N/A
Study type: Interventional

Pegylated interferon α-2a(Peg-IFN-α) not only inhibit viral replication, but also play an important role in immune regulation, while Nucleoside analog(ue) drugs only inhibit viral replication. In hepatitis B infection, Treg cells Regulatory T cells played a negative role in immune. This study was aimed at investigating the changes of Treg cells frequency and function, and the expression of costimulatory molecules during Peg-IFN-αand nucleoside analog(ue) therapy.Meanwhile, the investigators wanted to verify whether Peg-IFN-α suppressed the virus, which led to the decline of Treg cells frequency and function;negative regulation of Tregs for immune cells diminished, hence, the function of immune cells recovered.

NCT ID: NCT03210467 Recruiting - Clinical trials for Chronic Hepatitis B Infection

The Changes of Plasmacytoid Dendritic Cells Frequency and Function During Antiviral Therapy

Start date: January 2016
Phase: N/A
Study type: Observational

Pegylated interferon(IFN) α-2a(Peg-IFN-α) not only inhibit viral replication, but also play an important role in immune regulation, while entecavir(ETV) drugs only inhibit viral replication. In hepatitis B infection, Plasmacytoid Dendritic Cells(pDCs) are the main effector cells in early antiviral innate immune response. This study was aimed at investigating the changes of pDCs frequency and function, and the expression of costimulatory molecules CD86(Cluster of Differentiation antigen 86) during Peg-IFN-αand entecavir(ETV) therapy.Meanwhile, investigators want to verify whether Peg-IFN-α suppressed the virus and the reduction of virus led to the recovery of pDCs function, or Peg-IFN-α enhanced pDCs function which gave rise to the decline of the virus.

Start date: January 2016
Phase: Phase 4
Study type: Interventional

Pegylated interferon α-2a(Peg-IFN-α) not only inhibit viral replication, but also play an important role in immune regulation, while Nucleoside analog(ue) drugs only inhibit viral replication. In hepatitis B infection, CD8+T cells are the main effector cells in adaptive immune response. This study was aimed at investigating the changes of CD8+T cells frequency and function, and the expression of costimulatory molecules during Peg-IFN-αand nucleoside analog(ue) therapy.Meanwhile, the investigators want to verify whether Peg-IFN-α suppressed the virus and the reduction of virus led to the recovery of CD8+T cells function, or Peg IFN - alpha enhanced CD8+T cells function which gave rise to the decline of the virus.
