Active clinical trials for "Hepatitis"

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.

This study is a retrospective analysis to explore the incidence of hepatitis B virus reactivation after withdrawal of prophylactic antiviral therapy, the efficacy and safety of chemotherapy, and overall survival rate in lymphoma patients with hepatitis B virus infection.

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 present study is conducted in order to assess the acceptability of Hepatitis B vaccination in French general population before and after reimbursement of the paediatric vaccine InfanrixHexa. Four measurements are planned, first before reimbursement and the others at year 1, 2 and 3 after reimbursement.

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 safety surveillance study is being conducted in accordance with Korea Food and Drug Administration (KFDA) "Basic standard for reexamination of new drug". Primary objective: To assess the safety of AVAXIM 160U (Hepatitis A vaccine) administered under the routine practice, according to Korea Food and Drug Administration "Basic standard for reexamination of new drug" based on the pharmaceutical law in Korea.

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).

This will be a multi-center study in Hong Kong. This is a retrospective-prospective study in HBeAg-negative chronic hepatitis B patients. HBeAg-negative patients on entecavir followed up in the liver clinics will be identified from the existing database. All patients had HBV DNA testing every 6 months as a clinic routine. Serum HBsAg levels will be tested in the residual serum samples at the pre-treatment and last follow-up visits. Eligible patients will be discussed on the plan of stopping entecavir therapy. All patients will have written informed consent before recruited into this study. All patients will be followed up for 12 months after stopping entecavir treatment. As entecavir is most commonly used antiviral drug in Hong Kong and in the Western countries, the investigators aim to investigate and validate the use of serum HBsAg quantification to guide the timing of stopping entecavir in HBeAg-negative patients. The results of this study will provide scientific evidence on the use of this new serum marker to predict sustained remission after stopping entecavir. In the long-run, it can improve patient compliance, reduce the need of long-term antiviral and reduce the drug cost in the management of HBeAg-negative chronic hepatitis B. All patients will stop entecavir according to the Asian Pacific guideline with written informed consent and close subsequent monitoring. In the protocol, there is a safety net for re-treatment. There will not be any invasive procedure. There is no major ethical issue.

In order to clarify the association between HBV mutations appearing before and during interferon therapy and the therapeutic effects, serial serum samples from 100 HBeAg-positive CHB patients undergoing peginterferon alfa-2a therapy will be collected and analyzed for the mutations of preS/S gene and BCP-preC/C region, particularly for the deletion mutations. Furthermore, Real-Time PCR will be performed to measure the ratios of wild-type HBV and deletion mutant HBV before and at the end of peginterferon alfa-2a therapy. Finally, statistical analysis will be done to elucidate whether the mutations of preS/S gene and BCP-preC/C region have any relation with the therapeutic effect of peginterferon alfa-2a.

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.
