Filter by:Hepatitis B virus (HBV) infection remains difficult to eradicate with about 240 million people living with HBV chronic infection. HBsAg clearance, correlated with a good clinical prognosis, is difficult to achieve even with antiviral treatments (3-14 %). HBV envelope proteins are essential for entry into hepatocyte and are targeted by the immune system. Molecular characteristics of HBV envelope proteins may favour better viral fitness at the entry step into hepatocytes and/or HBV escape from host immunity. Here we investigated whether variability of HBV envelope proteins can contribute to the differential responses to anti-HBV treatment in patients with HBsAg clearance or persistence.
This multi-center, post-marketing, observational study evaluates the real world safety and effectiveness of glecaprevir plus pibrentasvir use in participants infected with the hepatitis C virus genotype 1 - 6.
The aim of the study is to assess the health-related quality of life (HRQOL) and preference-based health utilities of chronic hepatitis B (CHB) carriers in different stages of illness. It will also estimate the cost-effectiveness of anti-viral treatments resulting from the prevention of the progression of disease from uncomplicated CHB carriers to cirrhosis and hepatocellular carcinoma (HCC). The following hypotheses will be tested: 1. Patients with chronic hepatitis B virus (HBV) have poorer health-related quality of life (HRQOL) than the general population; 2. Patients with more severe stages of chronic HB infections have lower health related quality of life and health utility values; 3. Anti-viral treatment can improve the HRQOL and health utility for patients with CHB infections; 4. The cost-effectiveness of different treatments for chronic HBV infections can be directly compared in terms of cost/QALY gained.
The goal of this study is to assess patients' attitudes and knowledge of Hepatitis C, analyze the variables that may influence patients' knowledge, and educate patients on Hepatitis C.
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.
