Active clinical trials for "Hepatitis B"

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.

A multicenter, observational study to evaluate the safety of Euforvac-Hib vaccine for active primary immunization against diphtheria, tetanus, pertussis, hepatitis B and Haemophilus influenza type B in infants.

The purpose of this study is to demonstrate the difference in frequency and level of liver function disturbance between patients on efavirenz based ART, and patients on nevirapine based ART in HBV and HCV co-infected patients, (and/or with patients with abnormal liver function prior to ART), in China. Liver function tests will be measured at baseline and follow-up.

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.

Human immunodeficiency virus/Hepatitis B virus (HIV/HBV) co-infections are frequently observed due to shared routes of transmission, with reported figures indicating 6-9% of HIV-infected individuals in developed countries are chronically infected with HBV. HIV infection impacts on the natural progression of HBV infection, increasing levels of HBV replication and the risk of liver-associated mortality. Liver diseases associated with HBV are affected by the antiviral drugs used for HIV infection (toxic side effects), the current immune function in the patient, by improvements in the immune system brought about by control of the HIV infection, and by the development of resistance to the antiviral agents used for both the hepatitis B and the HIV infection. Tenofovir (TDF) is a newer antiviral drug that is frequently used for HIV infection and is also highly active against hepatitis B; however it is still unknown whether resistance to TDF will eventually develop and how this will affect the long-term outcomes

This is a randomized cross-sectional study of the Swedish population. Blood samples will be collected from a subpopulation in order to estimate the age specific sero-prevalence of the Swedish population for diseases included in the National Immunization Program (NIP), and to affirm the population's protection against polio. To be able to recommend complementary immunizations to immigrated children, a sub study focusing on foreign born teenagers will also be done and compared to children of the same age born in Sweden.

The purpose of this study is to determine the effect of polymorphisms in the IL-1 gene complex on the development of chronic hepatitis and hepatocellular carcinoma.

Evaluation of novel point of care Hepatitis B diagnostic assays.

Primary Aims: Evaluate HBV (Hepatitis B Virus) infection prevalence among Druze in the Galilee. Educate the population in order to reduce transmission Increase awareness among primary care providers Secondary Aims: Identify chronic HBV infected patients who need to be followed and treated, Identify HBV infected women in a childbearing age Identify non immunized individuals and recommend vaccination Identify previously vaccinated individuals who are not immunized Identify previously vaccinated individuals who became infected Study Design: Study population is targeted to native Israeli Druze. We aim for evaluating up to 20,000 people from Druze communities in the Galilee area This work will be divided into three sections: Increasing awareness: lectures and local events will be taken place in the communities. Written information will be given and primary care-providers mainly family doctors, nurses and obstetric surgeons will be involved. All participants, upon signing a consent will: Fill up a questioner Checked for weight, height and waist circumflex Have a blood sample taken Results and recommendations will be forwarded to all participants

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.
