Active clinical trials for "Hepatitis"

The aim of this study is to prove the superiority of entecavir over lamivudine for preventing the risk of hepatitis B virus reactivation in patients with non-Hodgkin lymphoma on CHOP/R-CHOP.

This study is being conducted to develop new techniques for early diagnosis of liver disease. These techniques are: Shearwave Elastography (SWE) ultrasound and blood biomarkers. SWE ultrasound uses high-frequency sound waves to view soft tissues such as muscles and internal organs and measure stiffness. An ultrasound creates computer images that show internal body organs, such as the liver or kidneys, more clearly than regular x-ray images. Biomarkers are biological molecules found in the blood that provide important information about liver disease.

Hepatitis C (HCV) is an important global public health problem, disproportionately affecting HIV positive populations. Asia and Africa account for most of the co-infection burden, but access to HCV screening and treatment is still very limited. It is expected though, with the recent therapeutic advances and increasing global advocacy efforts, that HCV treatment should become a feasible option in the near future. Sihanouk Hospital Center of HOPE (Phnom Penh, Cambodia) is catering for one of the largest HIV cohorts of the country, followed in an ambulatory settings. In this cohort, the prevalence of HCV co-infection will be determined, as well as HCV genotype diversity and the severity of liver disease. The researcher will also explore the performance of simple blood tests/panels as predictors of significant fibrosis and/or cirrhosis. Patients will attend two study-visits. All adult patients of the HIV patient cohort of SHCH will be proposed HCV testing during their next HIV follow-up consultation, following the latest algorithm of the Centre for Disease Control (CDC) (May 2013). Anamnesis and clinical examination will focus, additionally to routine practice, on presence of general and HCV liver-disease related features. Laboratory analyses will include basic HIV tests (CD4), and tests for liver function such as Hepatitis B surface antigen (HbsAg) . During the following routine HIV follow-up consultation, the results of HCV testing will be explained to the patient. If the patient is HCV negative, his/her study participation ends here. If currently infected with HCV, the clinician will repeat the HCV liver-disease (extra-hepatic & hepatic) related anamnesis and clinical examination, and prescribe additional blood tests for the non-invasive liver fibrosis/cirrhosis blood panel tests, liver and kidney function. Patients will moreover be asked to undergo a liver ultrasound and liver stiffness measurements.

Background: - The hepatitis E virus causes an acute hepatitis that usually goes away by itself. Researchers in France studied people who received a liver or kidney transplant. They found that hepatitis E may not go away by itself in these people. It becomes chronic. This can cause serious liver disease. More than half the people who had organ transplant who had hepatitis E seemed to get a chronic infection. Researchers want to find out if hepatitis E happens this often in patients who have liver, kidney, or small bowel transplants in the United States. If it does, they want to know why. They want to know if chronic hepatitis E will become an important medical problem. This research might help improve care for people who have a transplant. It also might help researchers prevent the spread of hepatitis E. Objective: - To see how many patients who have received or are waiting for certain transplants have antibodies to hepatitis E virus. Eligibility: - Adults over age 18 who have had a liver, kidney, liver and kidney, or small bowel transplant, or are on a waiting list for one. Design: Participants will be enrolled from 3 transplant centers. Participants will complete a questionnaire. They will be asked about possible risk factors for hepatitis E exposure. Participants will have a blood sample drawn through a needle placed in a vein.

Study of seroprevalence of hepatitis E among HIV positive patient in Basque country, France in 2016.

This prospective observational study will investigate predictive values of virological response in pegylated interferon alfa-2a (Pegasys)/ribavirin (Copegus) treatment-naive participants with chronic hepatitis C. Participants will be treated with pegylated interferon alfa-2a and ribavirin as prescribed by the physician. Data will be collected for a maximum of 96 weeks.

The purpose of the study is to 1- detect and quantify HCV-PI resistant mutants with ultra-deep pyrosequencing (UDPS) technology, 2 - detect SNPs in P-glyocoprotein and CYP3A genes, in HCV mono-infected patients under/after Telaprevir treatment.

The Major goals of this project was to assess the natural history of disease in chronic hepatitis C patients with normal ALT and to determine the virologic and host factors associated with disease severity.

The hypothesis of this study is that pegylated interferon would cause cognitive deficits and mood changes in hepatitis C (HCV) positive subjects.

In last few years, most researches about hepatic complication after chemotherapy focused on hepatitis B virus (HBV). With adequate prophylaxis and monitor, HBV-related hepatitis flares can be prevented. In contrast, cancer patients with hepatitis C virus (HCV) infection are traditionally considered as relative safe to receive chemotherapy. However, two large retrospective studies recently showed that severe hepatitis could develop in 14-27% lymphoma patients with chronic HCV infection, including 3-4% hepatic failure. The risk factors to predict severe hepatitis are pre-treatment elevated ALT level and liver cirrhosis. Due to the lack of prospective studies, the dynamic changes of serum HCV RNA levels and the association of hepatitis are still unclear. Some epidemiologic studies demonstrated an association between HCV infection and B-cell lymphoma. Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma and several reports showed higher prevalence of HCV infection among DLBCL patients than the controls. HCV infected DLBCL patients are reported to have distinct clinical characteristics, such as older, more with elevated LDH levels, and more with extra-nodal involvement. Regarding the impact of HCV infection on prognosis, the results are conflicting. Taiwan is an endemic area of HCV but there are limited reports addressing the clinical characteristics and prognosis in this unique population. Therefore, the investigators initiate a prospective, multi-center observational study to clarify the dynamic association between serum HCV RNA levels and hepatitis in HCV-infected lymphoma patients treated with chemotherapy.
