Active clinical trials for "Hepatitis B"

The aim of this study is to determine that for hepatic dysplastic nodules in patients with chronic hepatitis B, instead of enhanced follow-up, whether early minimally-invasive ablation therapy can reduce the incidence of hepatocellular carcinoma.

This study is a retrospective analysis to identify factors influencing hepatitis B virus reactivation in patients treated with rituximab containing chemotherapy. Rituximab monoclonal antibody targeting CD20 induces B-cell depletion resulting in prolonged immune suppression. This leads to frequent reactivation of patients with a previous history of exposure to HBV or HBV carrier. We collect the clinical features and laboratory findings of patients satisfied the inclusion criteria as follows. Patients diagnosed with diffuse large B-cell lymphoma (DLBCL) or \ follicular B-cell lymphoma (FL). Patients who had received at least two cycles of rituximab-CHOP or rituximab-CVP as a primary treatment Patients with a history of previous exposure to HBV HBV surface antigen (HBs Ag) positive Or HBV core antibody (IgG anti-HBc antibody) positive Then, we compare the HBV reactivation group with the control group (HBV reactivation does not happen) to find factors influencing HBV reactivation.

Phyllanthus Urinaria - Adenosma Glutinosum - Eclipta Prostrata - Ascorbic Acid combination plus Tenofovir in treatment of acute and chronic hepatitis B. Method the combination of drugs derived from natural and artificial medicaments. Has stronger effect on immune system, effective good against HBV replication. This is a substantial new insight into the pathogenesis of disease, with a clear path toward clinical application, or which would lead to a substantial advance and perfect in management or public health policy.

The purpose of this study is to determine whether preemptive nucleoside analogue therapy or regular virologic monitoring is the preferred method in management patients with prior exposure to hepatitis B vius (HBV) and undergoing hematopoietic stem cell transplantation (HSCT).

The purpose of this study is to determine whether short-term Atorvastatin can increase the immunity response to hepatitis B vaccination in vaccine Nonresponders.

To evaluate and standardize umbilical cord specimen collection and laboratory procedures to evaluate cellular and serological immune responses in neonates and young infants

The aim of our study is to validate the non-invasive model which was constructed by our previous study for evaluating liver fibrosis or cirrhosis caused by hepatitis B virus in mainland China and to find a therapeutic regimen to reverse liver fibrosis and cirrhosis.

Hepatitis B virus (HBV) infection remains difficult to eradicate with about 240 million people living with HBV chronic infection. HBsAg clearance, correlated with a good clinical prognosis, is difficult to achieve even with antiviral treatments (3-14 %). HBV envelope proteins are essential for entry into hepatocyte and are targeted by the immune system. Molecular characteristics of HBV envelope proteins may favour better viral fitness at the entry step into hepatocytes and/or HBV escape from host immunity. Here we investigated whether variability of HBV envelope proteins can contribute to the differential responses to anti-HBV treatment in patients with HBsAg clearance or persistence.

Hepatitis B virus (HBV) infection is a challenging health problem. According to the World Health Organization, an estimated 240 million individuals (3.7%) suffered from chronic HBV infection worldwide. After acute hepatitis B virus (HBV) infection, the disappearance of hepatitis B surface antigen (HBsAg) had generally been believed to signify viral elimination. However, it now becomes clear that those subjects may have occult HBV infection which is defined as the presence of HBV DNA in the liver in the absence of HBsAg in the serum. Occult HBV infection usually accompanies antibody against hepatitis B core antigen (anti-HBc) and/or antibody against HBsAg (anti-HBs), but some cases might not have these serological markers (seronegative occult HBV infection) .

In this cohort study, patients with chronic hepatitis B who prior participated in TB1211IFN study and received at least 39 doses of peginterferon alfa will be enrolled. HBsAg/anti-HBs level, HBeAg/anti-HBe level, Serum HBV DNA load and alanine transaminase level will be test every year from the second year to the fifth year after the ending of peginterferon alfa treatment, and long-term benefit of interferon treatment will be evaluated.
