Active clinical trials for "Hepatitis C, Chronic"

The current gold standard for treatment of chronic hepatitis C is pegylated interferon plus ribavirin. Drug administration accuracy and ease of use will definitely determine treatment effectiveness. This is the idea behind the development and usage of the PegIntron pen (PegPen). Therefore, it is worthwhile to evaluate patients' satisfaction with this novel device. The results of the study will be used to improve PegPen training techniques for patients and health care providers.

Several psychiatric adverse events (eg, depression, fatigue, psychoses, behavior troubles, anxiety, irritability, deteriorated concentration, and insomnia) that are likely to occur during the treatment course with PegIntron plus Rebetol may prompt patients to discontinue their treatment early. The goal of this study is to assess whether a psychotherapy support program may contribute to a better adherence rate.

This is a long-term evaluation follow-up study of neurocognitive performance and emotional state in patients with chronic hepatitis C infection and a former (peg)interferon alfa-2b-based therapy. M.R. Kraus, G. Teuber, NN, NN (MPsych), M. Scheurlen Questions: Neurocognitive and psychiatric changes induced by interferon alfa-2b therapy in patients with chronic hepatitis C - are they fully reversible in long-term follow-up after the end of antiviral treatment? At least 12 months after the end of antiviral treatment - are neurocognitive and mood-related parameters even significantly improved as compared to pretreatment values? Is this possibly only true of patients with successful virus eradication? At least 12 months after the end of antiviral treatment, is there a significant difference between patients with and without sustained virological response with respect to neurocognitive performance, emotional state and quality of life? In the absence of clinically significant liver damage in patients with chronic hepatitis C - does the mere presence of the hepatitis C virus have any significant influence on neurocognitive or attentional performance? Does the study data support an additional indication for antiviral therapy in chronic hepatitis C? In the case of successful virus eradication, emotional state and - above all - is neurocognitive performance significantly improved even in the absence of severe liver damage?

The main objective of this study is to assess whether a recently-developed bioassay for the protein FGL2 can be used to predict the progression and/or response to treatment of Hepatitis C Virus disease in patients with chronic HCV infection. The hypothesis is that increased levels of FGL2 and increased numbers of T regulatory cells are associated with a failure to respond to treatment.

Aim To evaluate the effects of peginterferon and ribavirin therapy on the immune response in chronic HCV genotype 1,2 or 3 patients before, during and after treatment. Background Treatment of chronic hepatitis C (HCV) has shown a remarkable success. However, genotype 1 patients have reduced response rates. A better understanding and improvement of these results can now be considered the greatest challenge. In chronically infected patients, HCV-specific immune responses are generally weak, narrowly focused, and often dysfunctional. The presence of HCV-specific cells suppressing the immune response (regulatory T-lymphocytes=Treg) are able to suppress the immune response. These Treg are possibly responsible for the impaired immune response. Previous studies have indicated increased Treg frequency and activity of immune regulating mechanisms, locally in the liver, as a result of HCV re-infection. Hence, these Data highlight the importance of monitoring intrahepatic immune responses in addition to peripheral immune responses. Using the minimally-invasive technique of fine-needle aspiration biopsy (FNAB), it is now possible to obtain safe and frequent liver samples to monitor local antiviral immune responses in chronic HCV patients during antiviral therapy. Rationale and hypothesis of the study Our previous studies and current literature support the concept that Treg may contribute to HCV persistence by suppressing HCV-spec immune responses. The current study is designed to examine if peginterferon and ribavirin therapy affects the activity of Treg and DC, and if this results in enhanced HCV-specific immune responses. Design Single centre, translational and observational open label study with one arm of 20 genotype 1 patients and one arm of 7 genotype 2/3 patients.

The purpose of our prospective study was to evaluate the value of Doppler parameters and compare the diagnostic accuracy of Doppler parameters with various biochemical indices in predicting significant hepatic fibrosis (≥ F2) and cirrhosis (F4) in chronic hepatitis C (CHC) patients.

Chronic hepatitis C may relapse in simple chronic hepatitis C patients who initially obtained sustained virologic responses. Although the HCV SVR could be maintained in around 90%, the remaining 10% of these patients may develop hepatitis C relapse during follow-up. Therefore, it is important to follow up the long-term of these patients with dual chronic hepatitis B and C. From another aspect, for the treatment of chronic hepatitis B, the virologic and serologic responses may also not be durable. Alternatively, previous studies suggested that the therapeutic efficacy might not be seen in the study period, and incremental response might occur during long-term follow-up. Therefore it is also important to clarify the long-term outcome of treatment in this dually infected population. Evaluation of the long term effects of treatment with peginterferon alfa-2a plus ribavirin for patients with chronic hepatitis C/ hepatitis B co-Infection and chronic hepatitis C in the original study ML17862 is important. This present protocol is thus to assess whether the HCV SVR is sustained and to assess the durability of the HBV virologic and serologic responses or any incremental response during a 5-year follow-up period, including six months after end of the therapy in the original study and an additional 4 and half years in this project (5 years overall follow-up after the end of treatment). Specifically, we wish to assess the (1) sustained virologic response (SVR) of HCV in both populations, (2) incidence of HBsAg loss and HBsAg seroconversion (HBsAg loss and appearance of anti-HBs) in dually infected population, (3) ALT normalization or flare off-treatment during both populations, (4) reductions of HCV RNA from the original baseline levels in the two patient populations, and (5) reduction of serum HBV DNA off-treatment in the dually infected population.

Several factors are barriers to effective Hepatitis C care: 1) The majority of Hepatitis C Virus (HCV)-positive patients (45-85 percent) are unaware that they are infected; 2) Only a small minority of those in need of treatment receive it; 3) Members of minorities and older patients are even less likely to receive needed care; and 4) Until recently, even those who were treated had a low chance of clearing the virus or achieving cure; 5) It is possible that older attitudes and expectation of futility might continue to persist among patients and provider in primary care settings. Community Health Centers are often the most culturally appropriate and accessible choices, particularly for underserved populations, with the benefit of ongoing trust and relationships with patients. Therefore, these can be ideal places to deliver complex HCV care if they possess the needed expertise. However, most community-based primary care and community health centers lack access to Hepatitis C evaluation and treatment services, leading to a major public health problem. Thus, investigators propose to implement and evaluate a pragmatic trial to implement and evaluate a multi-disciplinary model for HCV treatment at Currently, the treatment initiation rates at each of these sites is estimated as less than 10%. The investigators hypothesize that our project will increase the rate of participation in all the steps of the HCV care cascade and ultimately lead to more than doubled rates of treatment uptake

This prospective, multi-center, observational study is designed to assess the real world effectiveness of paritaprevir/r - ombitasvir with dasabuvir (3DAA [direct-acting antiviral agent] ABBVIE REGIMEN) without ribavirin (RBV) and to describe baseline characteristics of participants with chronic hepatitis C virus (HCV) genotype 1b (GT1b) infection and compensated liver cirrhosis in Russia.
