Filter by: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).
The aim of the study was to verify the influence of Agaricus blazei (Murrill) ss. Heinemann (A. blazei) on the evolution of nutritional state and liver function in hepatitis C patients.
This study, conducted by the Beijing University First Hospital of China and the National Cancer (NCI), will try to identify genes associated with either susceptibility or resistance to chronic infection by the hepatitis B virus (HBV). Some people recover from HBV infection; others become chronically infected and may go on to develop severe liver disease such as cirrhosis or liver cancer. About 350 million people worldwide have chronic HBV infection. Of 120 million infected Chinese, 90 percent of children infected at less than 5 years of age and 10 percent of infected adults develop persistent infection. HBV-infected and non-infected healthy persons of Han ethnicity born before 1963 may be eligible for this study. Offspring of infected candidates (born in any year) may also be enrolled. Infected adults must have at least one infected parent or sibling. Persons who resided in Fusui County of Guangxi Zhuang Autonomous Region or in the Qidong district of Jiangsu Province for at least 6 months before 1986 may not participate. All participants (except offspring of the study subjects) will fill out a health questionnaire (providing information about eating, drinking, and smoking habits and a personal and family health history) and will donate no more than 20 milliliters of blood. The blood will be tested for antibodies, antigens, and other substances that may indicate infection with hepatitis viruses. Some of the blood will be sent to the NCI for DNA analysis to identify genetic factors that may influence clearance of the hepatitis virus after infection or progression to liver diseases associated with HBV infection. Infected patients who have had a liver biopsy in the past will be asked permission to examine tissue from the biopsy and to review laboratory results of any tests done for diagnostic and treatment purposes. When the study is completed, specimens sent to the NCI will have identifiers linking the material to the donor removed. The anonymous samples may then be used for other genetic studies. Specimens remaining in China will continue to have identifiers linked to them and may be used for future studies designed to identify who is at greatest risk of developing serious liver diseases. Participants who do not want their blood used for future studies may request that the samples be destroyed. Because children inherit one-half of their DNA from each parent, DNA samples from HBV infected study participants may provide additional information about the parent s DNA structure. Offspring who participate in this study will provide a DNA sample. The sample is obtained by swishing a mouthwash in the mouth for 30 seconds and then spitting the mouth wash into a cup. The DNA is then isolated from the mouth cells.
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.
The purpose of this study is to assess the safety and efficacy of repeated intravenous infusions of EMZ702 in combination with pegylated interferon and ribavirin in patients with chronic hepatitis C genotype 1.
The recurrence of hepatocellular carcinoma (HCC), two years after curative treatment is high, about 40% - 50%. Recently, it has been shown that intra-arterial radioactive lipiodol (Lipiocis®) could reduce the recurrence of cancer and increase the survival after resection of HCC developed on cirrhosis B. The aim of the present trial is to investigate the effect of Lipiocis® in preventing recurrence after curative treatment of HCC in patients with viral or alcoholic hepatitis related cirrhosis by surgical or percutaneous ablation.
To conduct epidemiological, laboratory, and survey research on volunteer blood donors within the United States to ensure the safety and availability of the United States' blood supply.
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.
To determine the risk of transfusion-transmitted hepatitis C virus (HCV) in cardiac surgery patients before and after donor screening for anti-HCV and surrogate markers of non-A, non-B hepatitis (NANBH). Also, to characterize donors who were HCV seronegative and who lacked surrogate markers at the time of donation, but whose recipient seroconverted to HCV.
