Active clinical trials for "Hepatitis, Viral, Human"

This study will draw from proven interventions to refine and pilot test a cue card driven computer-assisted intervention, along with HIV/STI testing, that will be tailored to each participant's demographic characteristics, risk behaviors, and biological test results. The specific aims of the proposed study are: To refine a cue card driven computer-assisted risk reduction intervention that will be tailored to each participant's demographic characteristics (e.g., gender, ethnicity), risk behaviors, and biological test results (HIV, hepatitis B and C, syphilis and herpes). To pilot test the tailored intervention's effects on sexual risk behaviors (e.g., frequency of unprotected sex, condom use), drug use during sex and injection risk behaviors (e.g., direct syringe sharing, indirect sharing practices) using a two-group randomized design that compares the tailored intervention with a delayed treatment control condition. To assess the feasibility and acceptability of the tailored intervention in a rural setting.

This randomized clinical trial will examine the effectiveness of a strategy of HIV and Hepatitis Care Coordination (HCC) consisting of testing, education, counseling and vaccination for methadone maintenance patients compared with standard Testing, Education, and Counseling (TEC).

A new approach to the evaluation of liver fibrosis has been proposed using PULSOMETRY. The objective is to evaluate the diagnostic performances of the FIBROSCAN technique, together with non-invasive techniques, and to determine how it is able to predict the histological fibrosis score, defined by the METAVIR score. This transversal study aims to compare the evaluation of hepatic fibrosis obtained by FIBROSCAN and histology (METAVIR score) in 2550 consecutive patients taken in charge for a liver biopsy. The results of the study will compare the respective performances of these techniques in the prediction of the METAVIR score, and help in the recommendation of the care of patients with viral hepatitis B and C; these methods will undergo a medico-economic study.

Little is known about the nature and extent of the disturbance in hepatic function and biliary hepatic clearance in chronic viral hepatitis, while the course of this disease, the functional implications and response to treatment are difficult to predict. This study aims to assess this in patients with chronic viral hepatitis B (CHB) and chronic viral hepatitis C (CHC) who are eligible for treatment in accordance with the established consensus guidelines in the involved countries. The pharmacokinetics of NRL972 will be determined at baseline (within one month of starting treatment), at 3-monthly intervals during treatment, for up to 12 months (or at the end of treatment), and at 3 and 6 months after the end on treatment. This will provide a clearer understanding regarding the use of the pharmacokinetics of NRL972 in detecting changes in biliary clearance during and after treatment for CHB and CHC.

To evaluate whether hepatitis B immune globulin with a high level of antibody against the hepatitis B antigen would be capable of interrupting maternal-fetal transmission of hepatitis B virus, the single most important route of hepatitis spread in the entire Third World.

To conduct a prospective study of pediatric transfusion recipients to determine the risk of transmitting various infectious agents by blood transfusion.

To define the natural history, immunologic, and genetic factors that influence the clinical outcome of hepatitis C in a cohort of hemophilic siblings.

Viral hepatitis is a serious world health problem affecting over 1 billion people worldwide. Presently the lack of highly effective treatments results in many patients requiring liver transplantation or death. The investigators have defined the role of a unique molecule FGL2 and its receptor fc-gammaR and its role in the pathogenesis of both experimental and human hepatitis. The studies proposed in the present proposal will test the hypothesis that measuring levels of fgl2 in plasma will identify individuals that will go on to develop chronic disease and inhibition of binding of fgl2 to its receptor will allow the host with both acute and chronic disease to develop an appropriate immune response and clear the virus. The studies will provide rationale for generation of new therapies to improve the treatment of patients with acute and chronic viral hepatitis by targeting fgl2.

To determine the prevalence of hepatitis delta virus (HDV) in a large cohort of hemophiliacs and to elucidate the role of HDV in the development and progression of liver disease in this population.

To compare the clinical, biochemical, and histological status of Non-A, Non-B post-transfusion hepatitis patients with that of patients who did not develop post-transfusion hepatitis.
