Active clinical trials for "Hepatitis B, Chronic"

The study was conducted to evaluate the effect of anti-viral treatment on long-term outcome on patients with chronic hepatitis B.

Chronic hepatitis B virus infection is an important cause of morbidity and mortality. Tenofovir disoproxil fumarate and entecavir were licensed for the treatment of hepatitis B virus infection. In this study, the investigators will try to make comparison between Entecavir and Tenofovir and investigate the efficacy.

IL-33 is a recently identified number of the IL-1 family. Hepatic over-expression of IL-33 has been recently linked to liver fibrosis. ST-2 exerts pro-inflammatory effects of IL-33. We aimed to determine ability of ST2 to predict fibrosis in chronic hepatitis B.

Persistent replication of HBV (47-55%) is frequently found in patients with HCC, which in turn leads to deterioration of liver reserve. Moreover, a large proportion of HCC patients who underwent curative therapy died from progressive liver decompensation rather than recurrence of cancer. It had been proved that anti-viral therapy for hepatitis C virus (HCV)-related HCC patients could reduce the rate of tumor recurrence after surgical resection. This is a prospective study to evaluate the efficacy of ETV therapy in chronic hepatitis B patients after receiving RFA therapy for HCC.

The purpose of this clinical research study is to provide entecavir to subjects with chronic Hepatitis B infection who have failed or who have demonstrated intolerance of marketed therapies or for those in whom use of these agents is contraindicated and that have no other available treatment options.

In this project proposal, the investigators will investigate the genetic alterations of Hepatitis B Virus (HBV) strains circulating in Belgian patients who developed end stage liver disease. Additionally, the investigators will compare and link these data sets with three genetic factors involved in immune system response.

More recent studies have shown that the HBV-infected population has a greater risk of development of hepatocellular carcinoma. Nevertheless, there are still a significant number of people chronically infected by HBV who do not develop the complication. Hence, there exist biological markers that could be indicator for the disease-inducing and carcinogenic potential of the virus.

In South America, the prevalence of HBV is variable but high (> 8%) in the Amazon basin. In some areas, a third of HBsAg carriers are also infected with HDV, a major comorbidity factor. The pre-core mutations are associated with the negative HBe Ag phenotype which is associated with a more severe course. These mutations are of increasing and high frequency. French Guiana is populated by populations of African, European and Asian origins with chains of viral transmission which are not known and viruses probably of different origins with variable virulence and transmission potentials.

This was a retrospective observational cohort study. The patients with chronic hepatitis B and cirrhosis who were treated with antiviral therapy in the Second Department of Liver Disease, Beijing Ditan Hospital, Capital Medical University from October 2008 to April 2020 were enrolled. Patients treated with antiviral drugs including interferon and/or nucleoside (acid) analogues lasting more than 6 months were included in the study. Interferon, nucleoside (acid) analogue monotherapy, combination therapy, sequential therapy, maintenance therapy and drug withdrawal therapy can all be included in the study. HBV DNA content, HBsAg/anti-HBs, HBeAg/anti-HBe, biochemical indexes, serum AFP and liver imaging (liver ultrasound) were collected before treatment (baseline), during treatment and after treatment. The virological response and clinical outcome after antiviral treatment for chronic hepatitis B were observed for at least 288 weeks, and the main evaluation indicators were the occurrence or reversal of cirrhosis complications, hepatocellular carcinoma and mortality. Secondary evaluation index: the influence factors of different clinical outcomes. To investigate the long-term virological response and clinical outcome of antiviral therapy in patients with chronic hepatitis B and liver cirrhosis and to clarify its influencing factors.

The XN-20, is a full blood count (FBC) analyser with an extended differential counting and flagging System. The XN-Series' individual channels allow real-time reflex analysis, and uses a two stage process to classify the white blood count (WBC) sub-populations and detect the presence of abnormal reactive and malignant cells. In regards to lymphocytes in the peripheral blood, the machine has the capacity to distinguish activated from non-activated T-cell subsets using a very small volume of EDTA sample (88uL) (including remnant sample from a standard full blood count) with results available in 1.5 minutes. It is a fully automated process and can be considered as an alternative rapid flow cytometry method. Objective of the SASA study: to investigate the signal pattern of white blood cells assessed using the XN-20 full blood count platform in patients with untreated viral infections i.e. HIV, HCV and HBV. The data from the analysis will be reviewed in conjunction with patient's demographic and clinical disease characteristics with the aim of detecting characteristic cell populations that can be used in the development of system flags for future studies.
