Active clinical trials for "Hepatitis C"

This study seeks to provide evidence of the effectiveness and obtain patient reported outcome (PRO) data for the interferon-free regimen of paritaprevir (PTV)/ritonavir (r) + ombitasvir (OBV), + dasabuvir (DSV), +/- ribavirin (RBV) in participants with chronic hepatitis C (CHC) in a real life setting across clinical practice patient populations in Romania.

The emergence of hepatocellular carcinoma (HCC) has prompted a search for a thorough understanding of the biology of one of its major causative agents, the hepatitis C virus (HCV). HCV particles acquire via budding and encapsidation cellular proteins. There is mounting evidence on several viral species that virion-bound proteins are prone to be involved either at the replication, budding/egress or entry/release steps of the viral cycle. Identifying such targets may yield ideal candidates for gaining insight on the dependence of HCV upon a restricted subset of host proteins, therefore providing refined sets of genetically stable targets for therapy. This project's goals are to set up adequate conditions for robust and reproducible purification of HCV virions in clinical samples, followed by the identification of their HCV-bound host proteins and the characterization of their functions. Proteomics profiling of HCV particles purified from clinical samples will be overlaid with proteins identified and characterized in cell culture grown HCV particles during my post-doctoral training, using clinical biomarker discovery grade criteria. Targets identified in both samples sets will be subjected to in vitro investigations using HCV-replicating cells. Conventional biochemical and imaging methods will be used in order to: (i) ascertain their physical association with HCV virions; (ii) define the modalities of their interaction with HCV proteins; (iii) decipher the topology and subcellular localization of their association with HCV proteins and virions; (iv) quantitatively assess their functional involvement in particle budding, egress or secretion and infectivity. A candidate that yielded satisfactory results in these experiments will be disclosed and further investigated at the level of structural biology, in collaborative research programs.

The interferon-free combination regimen of paritaprevir/r - ombitasvir with or without dasabuvir (ABBVIE REGIMEN) ± ribavirin (RBV) for the treatment of chronic hepatitis C (CHC) has been shown to be safe and effective in randomized controlled clinical trials with strict inclusion and exclusion criteria under well controlled conditions. This observational study is the first effectiveness research examining the ABBVIE REGIMEN ± RBV, used according to local label, under real world conditions in the Netherlands in a clinical practice patient population.

The purpose of this study is to evaluate the effectiveness of a simeprevir-containing hepatitis C virus (HCV) treatment regimen as measured by sustained virologic response (SVR).

The purpose of this observational study is to compare two approved treatment regimen(s) containing boceprevir and telaprevir, as part of standard of care for the treatment of hepatitis C.

This study will explore ways to improve the effectiveness of patient Self Management at a time when genetic test results guide new treatments that will dramatically increase the possibility of cure of the hepatitis C virus.The study will also focus on the interactions between provider and patients and the ways that technical work, adaptive work and adaptive leadership foster patient self-management.This proposed 2 year exploratory mixed-methods 12 longitudinal case study will explore patients' and providers' explanations for how and why they engage in technical work, adaptive work, and adaptive leadership and the ways in which these strategies promote or pose barriers to patients' self-management of Chronic Hepatitis C in the context of the new genetic test results and treatments. Specific aims are to: 1: Examine how technical work, adaptive work and adaptive leadership influence patients' perceptions of their likelihood of cure and how this work relates to self-management during 12 to 24 weeks of treatment for Chronic Hepatitis C. Research questions are: 1.1) How do patients describe their interactions with the providers? 1.2) How do these interactions shape patients' perceptions of the likelihood of cure? 1.3) How do patients' understanding of their interactions with the provider promote the use of or pose barriers to self-management during treatment? AIM 2: Describe providers' use of technical work, and adaptive leadership approaches during clinical encounters,to include nurse education visits. Research questions are: 2.1) What technical work, and adaptive leadership approaches do providers use when sharing treatment information with patients during the clinical encounters. 2.2) What explanations do providers give for how and why they use technical work and adaptive leadership approaches? AIM 3: Describe the trajectories of illness perceptions(Control/Cure sub-scale - Illness Perception Scale), symptoms (M.D. Anderson Symptom Inventory) , viral load, and self-management (Patient Activation Measure) in relation to patient and provider reports of technical work, adaptive work, and adaptive leadership from the index clinical encounter to the follow-up treatment response encounter (ranging from 12 to 24 weeks).

Background: - Hepatitis B and hepatitis C can cause liver damage. They can also cause serious illness, including liver cancer, and even death. This study will follow people who have hepatitis B or hepatitis C. The purpose is to understand more about how these viruses affect the immune system over the long term (up to 10 years). The study will also compare how these viruses affect people who do and do not have HIV, the virus that causes AIDS. Objectives: To do a long-term study of hepatitis B and hepatitis C infection. To study the effects of hepatitis B and hepatitis C infection in people do and do not have HIV. Eligibility: - People at least 18 years of age who have hepatitis B or hepatitis C and have a regular doctor for their medical care. Design: Participants will be screened with a physical exam and medical history. Those who do not have a regular doctor to provide medical care during the study will not be able to take part. Participants will have yearly visits with study researchers for up to 10 years. These tests will be done at each visit. Medical history and physical exam. Questionnaire (optional) on emotions, sexual behaviors, use of alcohol and drugs, and quality of life. Blood and urine tests, including HIV testing. Tissue sample collections for those who have had a liver or other tissue biopsy. Participants may leave the study at any time. They will receive the standard of care from their regular doctor throughout the study.

The purpose of this study is to determine whether ultrasound or CT scanning is more effective at detecting early liver cancer in patients with advanced liver disease.

Viral hepatitis is a serious world health problem affecting over 1 billion people worldwide. Presently the lack of highly effective treatments results in many patients requiring liver transplantation or death. The investigators have defined the role of a unique molecule FGL2 and its receptor fc-gammaR and its role in the pathogenesis of both experimental and human hepatitis. The studies proposed in the present proposal will test the hypothesis that measuring levels of fgl2 in plasma will identify individuals that will go on to develop chronic disease and inhibition of binding of fgl2 to its receptor will allow the host with both acute and chronic disease to develop an appropriate immune response and clear the virus. The studies will provide rationale for generation of new therapies to improve the treatment of patients with acute and chronic viral hepatitis by targeting fgl2.

The purpose of this study is to conduct a prospective, three-group study that randomly assigns 700 parolees, in a community residential drug treatment program, to enter one of three groups: 1) a PCPC (Parolee Comprehensive Care + Phone Coaching Program), which includes nurse case management and specialized hepatitis education sessions and the hepatitis A/B (HAV/HBV) vaccination series (to all eligible) and coach-facilitated mentoring (mostly by cell-phone); 2) a Parolee Brief Hepatitis Education + HBV vaccination + Phone Coaching (PBCP) Program, which includes brief hepatitis/HIV education, HAV/HBV vaccination and coach-facilitated mentoring; or 3) a Usual Care (UC) control program, which includes brief general health information, one-on-one coaching and the HAV/HBV vaccine.
