Active clinical trials for "Hepatitis C"

A high number of people are infected by viral hepatitises B and C without knowing it, especially vulnerable population such as the ones who come in consultation in continuous health care access center (Permanence d'accès aux soins, PASS). Now that these infections can be rapidly treated, it is essential to diagnose them the quickest possible. The Identification and Diagnostic Orientation Test (Test de repérage et d'orientation diagnostique, TROD) technique is a rapid tool allowing to screen for hepatitis B and C by a simple capillary sample. The study aims to evaluate the accptability of a systematic screening using TROD for hepatitis B and C in adults in a PASS consultation in Montpellier. We also want to estimate the prevalence of theses infections in the population, to describe the HBV and HCV care cascades, to evaluate the acceptability of vaccinal catch-up for HBV, and to describe people with hepatits.

The main risk factor for development of hepatocellular carcinoma (HCC) is cirrhosis of any etiology, with an annual incidence risk between 1-6%; currently the leading cause of death in patients with cirrhosis and the 2nd cause of death by cancer worldwide. Chronic hepatitis C (HCV) is the first single cause associated to cirrhosis and HCC in the Western world. With the advent of new direct antiviral agents (DAA) of chronic HCV infection, virological cure generally exceeds 90% of the cases. Previous studies have shown that the incidence of HCC is lower in patients with virologic cure after treatment with pegINF schemes. However, recently published data, open up more controversy regarding the incidence of HCC after virologic cure with DAA. An increasing incidence of HCC after virologic cure in patients treated with DAA has been observed, opening a paradox yet unexplained. This project proposes to answer the following clinical research question: in patients with HCV cirrhosis treated with DAA, is there a change in the incidence of hepatocellular carcinoma? To answer this question a prospective longitudinal cohort study of patients with Child Pugh A-B cirrhosis will be held at 3 years minimum follow-up. A minimum of 210 patients will be included with clinical or histological or non-invasive diagnosis of cirrhosis Child Pugh A or B, with HCV treated with DAA and without hepatocellular carcinoma at the time of enrollment. From this cohort, patients who develop HCC during follow-up will be identified. Routine screening will be done through ultrasound every 6 months in all subjects enrolled and the diagnosis of HCC will be according to recommendations of European and American guidelines.

The purpose of this study is to evaluate the feasibility of implementing a cohort of patients with Hepatitis C in order to generate a larger cohort for future studies

The purpose of this study is to validate the first round HCV early dynamics discovery within a larger population.

The relationship between cytomegalovirus infection and recurrence of hepatitis C in liver transplant recipients remains controversial. Although some studies (Teixeira et al., 2000; Singh et al., 2005)have not found an association between recurrence of hepatitis C and CMV infection, studies such as Rosen et al. show that 50% of patients with CMV infection suffered cirrhosis durig follow-up period, while between not-infected patients the rate was 11%. To clarify this question, a non-interventional study will be carried out in order to assess if CMV replication is a risk factor for graft dysfunction in liver transplant recipients.

We hypothesized that pretreatment nonresponder and responder liver tissue would show consistent differences in gene expression levels and that these differences could be used to predict treatment outcomes and this can obviate the need of the present therapeutic trial.We are interested in conducting a retrospective study using the data of patients suffering from chronic HCV infection who were treated in our department with a combination of PEGINTERFERON and RIBAVIRIN. All these patients underwent liver biopsy prior the treatment. Based on the clinical data available it is possible to determine the responders and nonresponders to this therapy.RNA will be extracted from the liver tissue and the expression of 5 genes(IFI15,IFI616,IFI1,OAS3,OAS2 )will be checked .The prediction power of the combination of these genes in differentiating responders from nonresponders will be determined.

The primary purpose of the ANRS 12332 HepNile study cohort is to assess in "Real-Life" condition the efficacy and the safety profile of new Direct Acting Antivirals (DAAs) introduced in the Egyptian National Treatment Programme for the treatment of Chronic Hepatitis C (CHC).

This is a multicenter, non-comparative, observational study that will recruit women with singleton pregnancy and chronic HCV infection to determine the natural history of chronic HCV in pregnancy and the rate of vertical transmission to their infants. All participants will be offered curative therapy with sofosbuvir/velpatasvir (Epclusa ®) after delivery and the cessation of breastfeeding. Subjects may be enrolled at any time after conception up through 36 weeks gestation. The management of subjects in pregnancy will be in accordance with ACOG guidelines and individual clinical judgment, however testing will include, but not be limited to, testing for HCV infection, HIV infection, HBV infection, HSV infection, group B Streptococcal colonization, HCV genotype, HCV viral load, as well as assessment of hepatic and renal function. Subjects will be followed on a schedule that is determined by their obstetric care providers throughout their pregnancy. Following delivery, infants will be evaluated at 12, 24 and 48 weeks of age, with testing for HCV RNA to be obtained at each evaluation. Vertical transmission is defined as two positive HCV RNA PCR tests, at least one before the 48 week infant visit, and again at the 12-month follow-up infant visit.

The hepatitis C virus is a major cause of chronic liver diseases, including cirrhosis and hepatocellular carcinoma, and infects approximately 3 % of the world population (150-170 million). It is estimated that approximately 80 % of patients with acute hepatitis C fail to eliminate the virus and become chronically infected Hepatitis C virus infection is strongly associated with the dysregulation of glucose homoeostasis such as insulin resistance and type 2 diabetes. Despite these findings of insulin resistance development via direct effects on insulin signalling pathway, the complex relationship between intrahepatic Hepatitis C virus infection and extrahepatic insulin resistance remains elusive. One of the countries most affected by Hepatitis C virus is Egypt. The Egyptian Demographic and Health Surveys measured antibody prevalence among the adult population aged 15-59 years at 10.0% in 2015-substantially higher than global levels. Several micro ribonucleic acids have been determined to play a key role in regulating viral replication and pathogenesis during infection. micro ribonucleic acid-122 expression is enriched in the liver, accounting for approximately 70 % of the total micro ribonucleic acid population in normal adult hepatocytes. Moreover, a particularly intriguing function of micro ribonucleic acid-122 involves its role in the Hepatitis C virus replication cycle. Antagonism of micro ribonucleic acid-122 not only reduces viral replication but also reduces Hepatitis C virus propagation by decreasing the expression of enzymes involved in lipid metabolism, which can enhance Hepatitis C virus replication in cell culture models.

Chronic viral hepatitis C is a public health problem and several management recommendations are available. According to the French High Authority of Health, hepatitis C screening consists of a targeted screening of people at risk of infection by the virus, in particular drug users, people from countries with a high prevalence of the virus or who have received care in those countries, people transfused before 1992, or people who are or have beenincarcerated . French government recommendations aim to achieve elimination of hepatitis C virus HCV (as early as 2025) and since April 2018 the European Hospital Marseille is engaged in this battle and organizes every year "the day without hepatitis" in the hospital. Since 2017, direct-acting antiviral treatments have become available in France to all patients infected with HCV, regardless of the degree of severity of their disease. These treatments are effective in more than 95% of cases and, in 2019, 18,000 people were cured. As of today, it is estimated that there are still 110,000 people likely to be treated in France. Among them, 75,000 are unaware of being HCV positive, people who need to be tested. With one of the largest volumes of digestive endoscopic examinations in France, the European Hospital Marseille may be a significant source of screening for hepatitis C. Our study proposes to evaluate hepatitis C screening in consenting patients hospitalized in the endoscopy department at the European Hospital Marseille.
