Filter by:The farnesoid X receptor (FXR) regulates hepatitis B virus replication through the bile acids pathway. EYP001a is a selective, synthetic FXR agonist under development for the treatment of hepatitis B. This Phase 1 study is designed primarily to assess Pharmacokinetics (PK) under fed and fasted conditions, and to assess the safety, tolerability and Pharmacodynamics (PD) of single oral doses of EYP001a in subjects with chronic HBV infection.
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.
Uptake, adherence, and completion of vaccination among HIV-infected adults were low, and their immune function and immune response to hepatitis B vaccination were also suboptimal, indicating that the current practice of hepatitis B vaccination can't protect HIV-infected adults from HBV infection. And the persistence of immunity induced by hepatitis B vaccination remains a challenge. This is a randomized, open-label trial, conducted among HIV-infected adults with drug rehabilitation. This study will compare the immunogenicity, immune persistence, and safety of three intramuscular 20µg and 60µg recombinant hepatitis B vaccines at months 0, 1, and 6 among HIV-infected adults.
The purpose of this study is to determine whether patient education improves Hepatitis C screening in the primary care setting.
Chronic hepatitis HCV-related is the most common cause of chronic liver disease in Italy. Patients with chronic hepatitis C present a prevalence of depressive disorders higher than that of the general population; moreover, it has been repeatedly demonstrated the presence of cognitive deficits and poor quality of life. Chronic hepatitis C therapy was based on the combined use of pegylated alpha-interferons (PEG-INF), and ribavirin. Recently, new therapeutic protocols have been introduced, and while some antiviral drugs, including the first-generation ones, were used only in combination with PEG-IFN and ribavirin, the second and third generation antiviral drugs protocols are interferon-free. However, because of the high cost, the access to interferon-free protocols is only for patients with advanced fibrous stages, or with concomitant extra-hepatic HCV-related diseases, or for transplanted patients. Many side effects, such as flu-like symptoms, and psychiatric symptoms (depression, anxiety, irritability, insomnia) are common during antiviral therapy with IFN. However, in patients with chronic hepatitis C, a high lifetime prevalence of major depressive disorder, panic disorder, and brief recurrent depression have been observed, irrespective of IFN treatment and the use of alcohol and narcotics; such associations between mood and anxiety disorders and chronic hepatitis C may reflect a high prevalence of bipolar spectrum disorders. The presence of severe psychopathological symptoms requires the reduction of posology and causes high rates of discontinuation of antiviral therapy. This project represents an innovative psychiatric and neuropsychological screening program for patients with chronic hepatitis C, eligible for antiviral therapy. 1. Primary objectives: 1. to verify the medium-term impact of new antiviral therapies on quality of life, psychological well-being and cognitive function in subjects with chronic hepatitis C; 2. to verify the predictability of specific psychopathological components and specific determinants on compliance with new antiviral therapies. 2. Main secondary objectives: 1. to verify the evidence of association between various psychiatric disorders and cognitive deficits and chronic hepatitis C; 2. to evaluate the relative weight of psychopathological and/or cognitive disorders on the efficacy of antiviral therapy and on quality of life.
The purpose of this study is to use an existing, unique clinical cohort: the longitudinal cohort of younger (21-40 years) and elderly (>65 years) subjects whose yearly influenza vaccine responses have been studied extensively since 2007, to gain molecular and cellular mechanistic insights into the impaired vaccine responses in the elderly.
The goals of therapy against chronic hepatitis B are to decrease the morbidity and mortality related to chronic HBV infection. Currently available antiviral therapy can suppress viral replication but only a small proportion attain functional cure, which is defined as HBV surface antigen-to-antibody seroconversion. Hepatitis B surface antigen (HBsAg) is a marker of persistent hepatitis B infection. It has been observed that patients who had both hepatitis B and hepatitis C, and who were treated for their hepatitis C with 12 weeks of ledipasvir/sofosbuvir for had a decline in HBsAg levels. This study hypothesizes that a similar decrease would be seen in mono-infected hepatitis B subjects over the course of 12 weeks treatment with ledipasvir/sofosbuvir.
During the course of chronic hepatitis B infection, patients may undergo hepatitis B surface antigen (HBsAg) seroclearance, resulting in undetectable circulating HBsAg. With the advance of sensitive nucleic acid detection techniques, HBsAg-negative subjects with detectable HBV DNA in sera or liver tissues can be identified. Patients who have undetectable HBsAg and yet detectable HBV DNA in sera or liver tissues are defined as having occult HBV infection (OBI). OBI as a cause of liver disease in HBsAg-negative patients remains clinically important [1,2]. Studies conducted by our research group had demonstrated that patients with HBsAg seroclearance could still develop flare of hepatitis B, advanced liver diseases and HCC [3-6]. Prevention of these complications in OBI patients by conventional intramuscular hepatitis B vaccination (HBVv) remains elusive with poor amnestic anti-HBs response [7]. The objective of this prospective double-blind randomized controlled trial is to evaluate the effect and safety of topical treatment with imiquimod immediately before intradermal vaccination with Sci-B-Vac™ in patients with OBI. Our a priori hypothesis is that imiquimod pretreatment would improve immune responses to Sci-B-Vac™ further in OBI patients, resulting in HBsAb conversion. Thereby preventing subsequent complications including flare of hepatitis, cirrhosis and HCC in these patients.
The interferon- and ribavirin- (RBV) free combination regimen of glecaprevir plus pibrentasvir (GLE/PIB) for the treatment of genotypes 1 to 6 of chronic hepatitis C (CHC) viral infection has been shown to be safe and effective in randomized controlled clinical trials. This observational study is an effectiveness research examining the regimen of GLE/PIB, used according to local label, under real world conditions in a clinical practice patient population.
The focus of the study is to identify viral factors and host immune responses that differentiate HBV-related HCC patients from HBV patients who have not progressed to HCC. To that end, the investigators will compare gene expression levels between HCC patients and non-HCC patients categorized into high and low risk profiles. The investigators will perform ANOVA to compare three groups (HCC, high risk, low risk). Multiple comparison corrections will be performed using Benjamini and Hochberg False Discovery Rate (FDR) with a 90% confidence that the discovery lists will contain no more than 5% false positives (FDR<0.05) (PMID: 12584122, 11682119). A p-value <0.05 is considered statistically significant using this multiple comparison correction approach. Post-hoc Student-Newman-Keuls or Tukey tests will be used following ANOVA for comparisons of HCC patients with high risk and low risk. If data are not normally distributed when log-transformed, then Kruskall-Wallis tests will be used. ANCOVA will be used to adjust for the effects of covariates, such as age, gender, and HBV genotype (B or C). Further, the investigators often use an additional 2-fold change criterion for significance because the investigators consider a fold change of this magnitude to be biologically significant. Hierarchical clustering analyses and principal component analyses will be used to visualize how well the genes separate the groups, or to discover new subgroups. For the analysis of SNVs, the exact binomial test will be performed and p-values will be adjusted by the Benjamini-Hochberg correction.
