Active clinical trials for "Hepatitis"

This is prospective, longitudinal cohort study involving HIV-positive, antiretroviral (ART)-treated, heavy alcohol drinking participants who have and do not have alcoholic hepatitis.

Subjects who eventually undergo treatment for HCV, we will gather treatment data (start and stop dates), and repeat CB-CAP analysis at weeks 4, 12, 24 and 72 (+/- 2 week window allowed at each time point) to determine whether CB-CAPs levels predict virologic response in treated subjects. Routine laboratory data will also be collected at these time points.

This study aims to evaluate the prevalence and severity of hepatic steatosis in CHB and investigate the relationship between hepatic steatosis and viral load, liver biochemistry, liver fibrosis, and inflammation in CHB

Primary Purpose: Evaluate the prevalence and incidence of HEV infection in MHD patients. Compare differences of the prevalence and incidence between the MHD patients and the control. . Secondary purpose: Analyze risk factors of HEV infection.

Project BEST is a clinical project funded by the Substance Abuse and Mental Health Services Administration (SAMHSA) to increase treatment to opiate dependent patients with mental illness in New Haven, CT and to prospectively follow everyone enrolled in buprenorphine care for as long as the individual takes buprenorphine to track the success of buprenorphine for the maintenance of opiate dependence.

Hepatitis E virus is a single-stranded positive-sense RNA virus with genome of approximately 7.2kb in length. The HEV genome is capped at the 5' end followed by a small untranslated region of 27 nucleotides and polyadenalated at the 3' end preceded by another UTR of 65 nucleotides . HEV has three open reading frames: ORF1, ORF2 and ORF3 that encode structural and non- structural proteins. ORF1 is the largest one, approximately 5,000 nt in length, located at the 5 ' end and encodes important proteins for the replication process (methyltransferase, papain-like cysteine protease, helicase, and RNA-dependent RNA polymerase). A noncoding, hypervariable region within ORF1 displays substantial genetic diversity; this region seems to modulate the efficiency of HEV replication. Notably, the differences in the genome size among different HEV strains are confined mainly to this region .ORF2 is located at the 3' end, encodes structural capsid proteins of 660 amino acids and contains three potential glycosylation sites. The ORF2 protein contains multiple immunogenic sites and neutralizing antibodies are directed against it al., .The essential region in the protein for immunogenicity is 452aa-617aa and the neutralizing epitopes have recently been shown to be conformational .ORF3 is located between the other two reading frames and encodes a small phosphoprotein of 123 amino acids. Its exact function has not been yet determined, however, multiple functions have been proposed. It is thought to interact with cellular mitogen-activated protein kinase phosphatase and other extracellular kinases, promoting cell survival through activation of intracellular signaling pathways .Moreover, the binding of the ORF3 encoded protein to host-specific proteins seems to influence the pathogenesis of HEV infections .A schematic drawing of the HEV genome is described in Figure 1 .

The aim of this study was to evaluate knowledge and behavior of physicians regarding Hepatitis B Virus. The investigators designed a 30-item self-administered questionnaire assessing physicians' knowledge and behavior regarding chronic Hepatitis B Virus infection. These results provide data support for updating guidelines, continuing training, and even developing policies in medical insurance.

Screening, diagnosis and treatment of HCV in PWID, should be part of a harm reduction strategy. Treatment of HCV infected PWID should be delivered in a multidisciplinary care setting with services to reduce the risk of reinfection and for management of the common social and psychiatric comorbidities in this population. More frequent diagnosis, new methods that prevent loss of tracking, and access to antiviral treatment are all strategies that must be implemented jointly if the prevalence of HCV infection in our setting is to be reduced.

The purpose of this study is to determine whether patient education improves Hepatitis C screening in the primary care setting.

Sofosbuvir plus daclatasvir with or without ribavirin is one of the currently recommended treatment option for chronic hepatitis C. The objectives were to identify factors associated with sofosbuvir/daclatasvir plasma concentrations variations and to evaluate their impact on viral kinetics.
