Filter by:Clearance of HCV infection requires early and multi-specific HLA class I restricted CD8+ T cell and class II restricted CD4+ T cell responses to both structural (Core) and non-structural HCV proteins (NS3, NS4A, NS5A, NS5B). Dendritic cells (DCs) are professional antigen-presenting cells that link innate and adaptive immune responses, and play a major role in priming, initiating, and sustaining strong anti-HCV T cell immune responses. The general objective of this study is to evaluate safety, feasibility and clinical efficacy of therapeutic vaccination in genotype 1 HCV patients using autologous DCs pulsed with recombinant HCV-antigens (Core and NS3). Expected effects: DC vaccination induces Core/NS3-specific immune response and reduces viral load in patients with chronic HCV-infection.
In the medical literature there case reports that Harvoni improves symptoms in patients with PCT. However, this has never been systematically tested. Therefore, the purpose of this study is to assess whether Harvoni alone is an effective therapy of active PCT in patients with Chronic Hepatitis C.
The purpose of this study was to evaluate the efficacy of 8 and 12 weeks of treatment with a fixed dose combination (FDC) of elbasvir (EBR) 50 mg + grazoprevir (GZR) 100 mg (i.e., MK-5172A) as assessed by the percentage of participants with hepatitis C virus (HCV) genotype (GT) 4 infection that achieve sustained virologic response (HCV ribonucleic acid [RNA] < Lower Limit of Quantification [LLOQ]) 12 weeks after the end of study therapy (SVR12). This study also evaluated the safety and tolerability of EBR/GZR.
The purpose of this protocol is to obtain pharmacodynamic and pharmacokinetic data on ABI-H0731 and to provide the opportunity for preliminary evaluation of combination therapy of ABI-H0731 with currently approved antiviral treatment for chronic hepatitis B.
Compare Hepatiis C Virus (HCV) detection between oral squamous cell carcinoma (OSCC) and normal tissues, to determine the possible relationship between HCV and OSCC.
hepatitis C virus (HCV) has traditionally been treated in subspecialty health centers given the complexity of older pegylated interferon containing regimens, formerly the standard of care. This model has persisted into the modern era of direct anti-viral agents (DAAs) despite their relative simplicity, creating a bottleneck of human resources necessary to fight the largest infectious epidemic in North America. In addition, stigma and fear over cost has lead payers to restrict treatment in People Who Inject Drugs (PWIDs), even though a majority of new infections occur in this population. This study evaluates the effectiveness of treatment of HCV with elbasvir-grasoprevir in PWIDs in a real world, community health clinic setting. There are two prospective cohorts of PWIDs of 25 patients each, both in primary care-based community health clinics in Portland, Oregon. Cohort one is actively engaged with ambulatory medication assisted therapy with buprenorphine or extended released injectable naltrexone. Cohort two maintains active injection drug use with needle exchange and risk reduction education. These groups are compared to a 50 patient retrospective cohort of people with substance use disorders at tertiary care hepatology-based treatment program. All patients have genotype 1 or 4 HCV and are treated with elbasvir-grasoprevir for 12 weeks. The investigators hypothesize there is no difference in sustained viremic response at 12 or 48 weeks post-completion of treatment (SVR 12, 48) when treating patients in a community health clinic setting as compared to the standard-of-care subspecialty setting.
Objective: Pegulated Interferon α2 plus ribavirin is a treatment of choice in patients with chronic hepatitis C infection. This study was conducted to find out the frequency of different IL-28B (rs12979860) genotypes in patients with chronic hepatitis C (HCV genotype type 2 & 3) infection treated with Pegulated Interferon α2 plus ribavirin and to evaluate the role of IL-28B genotypes in achieving Sustained Virological Response (SVR). Methods: In this non-randomized observational study, ninety eight (98) patients with diagnosis of chronic hepatitis C were included. In all patients, Peg-IFN plus Ribavirin were given in standard doses for 24 weeks. End treatment response, sustained virological response, and relapse rate were the primary endpoints of this study. Analysis of IL28B (rs12979860) polymorphism (CC, CT and TT) was performed by PCR-RFLP protocol.
A Phase 3b, single arm, open-label, multicenter study in treatment naïve adults with chronic HCV infection and compensated cirrhosis to assess the safety of 8 weeks of treatment with glecaprevir/pibrentasvir and to demonstrate the efficacy of the sustained virologic response 12 weeks post dosing (SVR12) rates of 8 weeks of treatment with glecaprevir/pibrentasvir compared to the historical SVR12 rates of 12 weeks of treatment with glecaprevir/pibrentasvir.
The purpose of the OPDEP pilot study is to assess the feasibility of implementing a pre-operative HIV / HCV / HBV screening proposal for all persons over 18 years of age and refer for surgical intervention under general anesthesia in the Department of Stomatology of the Pitié-salpêtrière hospital. Patients undergoing treatment in Stomatology have particular areas at risk for the infections we are looking for: young patients, precarious situation, drug use, migrants ... The aim is to evaluate the conditions for a generalization of screening in the framework of the preoperative assessment.
Objective: To coordinate active tracing of chronic hepatitis C patients lost to follow-up to inform them about there disease severity and treatment options. Study design: This is a prospective cohort study, which will start as a pilot study in the Radboudumc Population: lost to follow-up chronic hepatitis C patients in the region Nijmegen. This so-called lost population consists of all patients, that in the past have been identified at the Radboudumc but who are currently lost to or have been withdrawn from follow-up. The time-span of interest will be 2000-2015. We estimate that this project will retrace 100 lost patients through this search.
