Active clinical trials for "Hepatitis C, Chronic"

The purpose of this study is to evaluate the efficacy and safety of low-dose interferon-alfa-2b plus ribavirin compared to the standard-dose of the same combination in patients with chronic hepatitis C.

The response rate to interferon-based anti-viral therapy for chronic hepatitis C is lower in patients who are obese. However, it is not clear whether this is related to suboptimal dosing of the medication or alterated response in obese patients. Alterated immune response had been reported in obese patients. The goal of current study is to determine the immune response to interferon in obese compared to non-obese chronic hepatitis C in an tissue culture system.

EVERYONES HCV is a retrospective review of all previous Hepatitis C (HCV) testing and diagnosis in NHS Tayside. The aim of this study is to analyse and compare the different Hepatitis C diagnostic pathways with a view to determining the most cost effective combination of methods of diagnosing HCV infection in a typical developed world population.

Chronic hepatitis C virus (HCV) infection, an important cause of morbidity and mortality worldwide, is a significant problem in kidney transplant recipients (KTRs) given its high prevalence in patients undergoing hemodialysis. Interferon based regimens were cornerstone of treatment of HCV infection in the past; however, due to their low efficacy and high rates of adverse effects, they have been abandoned in the new era of direct acting antivirals (DAAs). Several studies demonstrated the efficacy and safety of DAAs, yet data regarding clinical practice of these agents in KTRs is still needed. Therefore, we conducted a study using our registry data to evaluate the efficacy and safety of DAAs in KTRs.

Chronic hepatitis C infection (CHC) is usually asymptomatic; nevertheless, there are studies that show that up to two thirds of patients may present some type of extrahepatic manifestation. The most frequent extrahepatic manifestation is type II mixed cryoglobulinemia (MCG-II) and clinically the most common presentation is leukocytoclastic vasculitis (LCV) with palpable purpura that affects the lower extremities. It is estimated that up to 80% of MCG-II cases are due to CHC. Also, previous studies have demonstrated that CHC prevalence is higher in patients with autoimmune diseases compared with general population. Therefore, if vasculitis is an extrahepatic manifestation of CHC, then the prevalence of CHC infection in this group of patients could be higher than the prevalence reported in general population. The aim of the study is to know the prevalence of CHC, determined by serological rapid test for hepatitis C screening, then all positive cases will be confirmed by quantitative viral load, in patients who consult primarily to a rheumatology department for "vasculitis" or other potential hepatitis C extrahepatic manifestations (rheumatological conditions).

This study seeks to assess the effectiveness of Glecaprevir plus Pibrentasvir in participants with chronic hepatitis C in a real-life setting across clinical practice populations in the Russian Federation.

This is a one-time cross-sectional survey study of approximately 200 self-identified black or African-American patients who have had chronic hepatitis C viral infection (HCV) that will evaluate patients' willingness to participate (WTP) in health/medical research related to HCV and attitudinal factors that might be associated with WTP, such as benefits and barriers to research participation, mistrust of physicians/researchers, health literacy, and knowledge of health/research studies.

The objective of this study is to assess the effectiveness of the glecaprevir/pibrentasvir (GLE/PIB) regimen in adolescent participants aged 12 to <18 years of age with chronic hepatitis C (CHC) in clinical practice in the Russian Federation. The study also plans to assess effectiveness of GLE/PIB in subpopulations of interest like co-infected hepatitis C virus (HCV)/human immunodeficiency virus (HIV) adolescents, in various HCV genotype/subgenotype, cirrhotic and non-cirrhotic participants, treatment-experienced (prior treatment with pegylated interferon (pegIFN) or IFN, and/or Ribavirin (RBV) and/or sofosbuvir [PRS]) and treatment-naïve, adolescents who use drugs (PWUD) and non-drug users.

Mixed cryoglobulinemia (MC) is common in patients with chronic hepatitis C virus (HCV) infection. Direct-acting antiviral (DAA) regimens are today very effective with sustained virological response rates (SVR12) above 90%. The objective of this study was to investigate the impact of DAA therapy on cryoglobulin clearance in patients with HCV-associated MC.

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. Primary objectives: 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; to verify the predictability of specific psychopathological components and specific determinants on compliance with new antiviral therapies. Main secondary objectives: to verify the evidence of association between various psychiatric disorders and cognitive deficits and chronic hepatitis C; to evaluate the relative weight of psychopathological and/or cognitive disorders on the efficacy of antiviral therapy and on quality of life.
