Active clinical trials for "Hepatitis A"

Immune globulin is effective about 85% of the time in preventing hepatitis A in people who have been exposed, if it is given within 14 days of exposure. Several lines of evidence suggest that hepatitis A vaccine might also be effective in this setting, and vaccine has the advantage of providing long term protection. In this study, we compare how well immune globulin and hepatitis A vaccine work in preventing clinical hepatitis A in household contacts of persons with the disease. The study's hypothesis is that the the proportion of exposed household contacts who receive hepatitis A vaccine within 14 days of exposure and develop hepatitis A disease will be similar to the proportion of exposure household contacts who receive immune globulin within 14 days of exposure and develop hepatitis A disease.

This is a non-randomized, open-label study of a fixed dose combination (FDC) of elbasvir (50 mg) and grazoprevir (100 mg) (EBR/GZR or MK-5172A) in participants with chronic hepatitis C virus (HCV) genotype 1 (GT1) infection with advanced fibrosis with and without human immunodeficiency virus (HIV) co-infection. All participants will be either HCV treatment naïve (TN) or treatment experienced (TE).

Hepatitis B (HBV) and hepatitis C (HCV) are prevalent all over the world, which seriously threatens public health. In 2016, the World Health Organization(WHO) put forward the goal of eliminating the threat of viral hepatitis to public health by 2030. However, at present, the diagnosis rate and treatment rate of chronic HBV and HCV in China are still far from the goal put forward by WHO. Therefore, for China, the elimination of viral hepatitis is still a public health problem that needs a long time to face. This study aims to screen and follow up HBV and HCV patients in Danzhou City, Hainan Province, so as to understand the epidemiological characteristics and long-term prognosis of HBV/HCV patients.

Following a transplant for hepatitis C cirrhosis, the infection comes back in 70-90% of cases and over time causes fibrosis and eventually cirrhosis of the new liver. The aim of this study was to see if the frequency of liver fibrosis was different with cyclosporine microemulsion than tacrolimus

In Mali, migration from rural zones is a cultural phenomenon existing since 1970. During the dry season (9 months), an important number of young women leave their villages and migrate towards urban zones to seek for a job. In Bamako, the estimated number of housekeepers is 100 000 coming from rural regions and aged between 11 and 19 years. The current healthcare offer seems to be non-adapted to their particularities. This is a community-based research constructed on the basis of the activities of two NGOs in Mali: ADDAD (association for the defense of the rights of Housekeepers and domestic helpers ) and ARCAD Santé PLUS (the main NGO for healthcare access for HIV, hepatitis, and sexual health services). The research is conducted by the SanteRCom team in the UMR1252 SESSTIM research unit. The main objective of this observational study is to study the knowledge, beliefs, behaviors and practices in terms of health in general, and sexual health in particular; and to assess the acceptability of an offer of community-based prevention and health services provided by ARCAD Santé PLUS integrated in the activities of ADDAD. The integrating of community-based healthcare offer in a familiar and reassuring framework, such as that of ADDAD, should promote access to health services among housekeepers. The research is organized in 3 stages: Preliminary qualitative survey based on focus group discussions. Allowing the identification of the housekeepers' needs in terms of prevention and healthcare services; and the behavioral particularities of the housekeepers community. It is planned to conduct 7 focus groups including between 42 and 56 housekeepers. Communication and awareness campaigns in the regions of origin of housekeepers. Campaigns will be constructed on the basis of the results obtained from the preliminary qualitative survey. Communication and awareness campaigns in Bamako; community-based activities for housekeepers will be organized 3 times per week during 5 months by the NGO ADDAD. Activities will include the community-based offer of prevention and healthcare services provided by the NGO ARCAD Santé PLUS, i.e. the novelty in the ADDAD's activities. A quantitative and qualitative surveys will be conducted over 5 months with participants recruited during the community-based activities. It is expected to enroll at least 1134 housekeepers, and to conduct a maximum of 25 individual interviews with selected housekeepers.

This study will evaluate the humoral and cellular immune responses to a hepatitis B vaccine booster in healthy adults which received a full course of neonatal hepatitis B vaccination 20-23 years ago.

The purpose of this study is to determine whether obese people do not respond to hepatitis C treatment as well as lean people. This research studies whether obese people will show higher sustained virologic response rate if they lose weight by Orlistat use and dietary and lifestyle modification.

Substance users are a vulnerable group that should be prioritized in HCV (Hepatitis C Virus) elimination efforts in Mexico and in which it is feasible to carry out micro-elimination programs. It is an important group to treat both because of its high prevalence and because of the dynamic spread of infection among the general population. HCV seropositivity has not been documented in this group of people in Mexico City, the metropolitan area and the northern states of the country, nor has the sustained viral response been evaluated in this group of patients in the Mexican population.

This is a randomized, multi-site, open-label trial of a fixed-dose combination of Grazoprevir (MK-5172) and Elbasvir (MK-8742) versus Boceprevir (BOC) / Pegylated Interferon (P) and Ribavirin (R) in treatment-naive and prior treatment failure genotype (GT) 1 hepatitis C virus (HCV)-infected participants. The primary hypothesis is that the proportion of treatment-naive (TN) and prior treatment failure (PTF) participants treated with grazoprevir + elbasvir achieving sustained virologic response (undetectable HCV ribonucleic acid [RNA]) 12 weeks after the end of study therapy (SVR12) will be greater than the proportion of BOC/PR-treated participants achieving SVR12.
