Active clinical trials for "Hepatitis B"

It is estimated that 350-400 million people worldwide are chronically infected with hepatitis B virus (HBV). Cirrhosis and hepatocellular carcinoma are major complications of chronic HBV infection and are responsible of about 500,000 deaths each year. Although some predictive factors of the outcome of chronic HBV infection were reported, it remains needed to more precisely determine the factors which are associated with the outcome in non-selected patients. Indeed, these factors should help to identify patients who are likely to have a better or worse evolution of their chronic HBV infection over time and thus, to adapt their clinical management and monitoring.Therefore, our purpose is to constitute a "real-life" cohort of non-selected patients to create a database of epidemiological, clinical, biological, virological and therapeutic parameters, in order to determine factors associated with the outcome of chronic HBV infection.

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.

The " CirB-RNA " cohort aims to create a biological collection associated with clinical and biological data from patients with hepatitis B infection. This project is part of a much larger program that aims to characterize and quantify circulating viral RNAs as a possible new biomarker of hepatitis B functional cure.

In this study, treatment-naïve HBV-related cirrhosis patients were retrospectively enrolled at the first episode of decompensation (ascites or variceal hemorrhage). Patients were followed up every 6 months until death /liver transplantation or for 5 years. Clinical data from medical records about past history, first decompensated events, second /further decompensated events, HCC, and death/ liver transplantation were retrospectively collected. In this retrospective study, the incidence of re-compensation and its clinical characteristics were mainly explored.

This is a multi-center cohort study in which the Real-time Tissue Elastography® measurements will predict prospectively the incidence of hepatocellular carcinoma, the incidence and severity of gastroesophageal varices ascites and decompensated cirrhosis in hepatitis B or C patients.

Data from this study will provide the first information how the innate immune system may be altered in HIV-HCV and HIV-HBV co-infected individuals, and describe Toll-like receptor changes with HIV co-infection therapy.

1. To acknowledge the prevalence of renal insufficiency and kidney-related diseases in patients with chronic hepatitis B in China through epidemiological surveys in outpatient clinics of about 150 hospitals across the country; 2. To analyze the related factors of renal insufficiency and kidney-related diseases in domestic patients with chronic hepatitis B from the aspects of demographic characteristics, family history, antiviral treatment, nephrotoxic drug use history, etc.

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.

Viral hepatitis B, C and Δ represent a global public health problem for which France was very early mobilized. Despite this, in its foreword, the Dhumeaux report on "Management of people infected with hepatitis B or hepatitis C viruses" identifies a residual area of weakness in this care that is the incomplete regional epidemiological data in the Overseas Territories. The specific ethno-socio-cultural characteristics of these territories make it difficult to transpose data from the mainland France. This study aims at improving our knowledge on the characteristics of patients with hepatitis B, C and Δ in Reunion Island, their follow-up, their evolution and complications.

The purpose of this study is to investigate the incidence of liver injury by statins in coronary heart disease (CHD) patients with history of hepatitis B virus (HBV) infection.
