Active clinical trials for "Hepatitis"

As HBsAg clearance is uncommon in chronic hepatitis B (CHB) patients on nucleoside analogues (NAs) therapy. The purpose of this study is to optimize HBsAg clearance in CHB Patients with sequential treatment of pegylated interferon alpha-2b and NAs.

The majority of childbearing age women with hepatitis B virus infection were still in the immune tolerance period. Our recent research had shown that most puerperae after delivery had elevated ALT level. However, there is no withdrawal time recommendations after childbirth at present.Through the study of hepatitis occurrence after delivery and drug withdrawal, the investigators explore the withdrawal time of antiviral treatment during pregnancy.

The current study is a prospective, randomized, open, multi-center investigation. The aim of the study is to investigate whether the HBeAg seroconversion rate can be improved if applying combination therapy in HBeAg positive CHB patients who has achieved HBVDNA<105copies/ml，HBsAg≤5000IU/ml, ALT≥ 2ULN or Liver histology G2S2.

This is a study to test whether vaccination with HAVpur Junior against hepatitis A provides protection that is non-inferior to the protection afforded by vaccination with Havrix 720 Junior.

Primary objective: Compare Pegasys RGT overall response rate (i.e., HBeAg seroconversion rate) with Pegasys mono historical response rate at week 72 (48 week treatment with 24 week follow up) Secondary objective : The changes of HBsAg titer The rate of combined HBeAg seroconversion and HBV DNA < 300 copies/mL The rate of serum HBV DNA < 300 copies/mL ⅳ. The rate of ALT normalization The rate of HBsAg loss ⅵ. The rate of serum HBV DNA < 10,000 copies/mL

Currently, peginterferon alfa-2a or oral nucleos(t)ides are approved for the treatment with HBeAg negative CHB, with the overall ALT normalization and HBV viral suppression far from satisfactory. Therefore, efforts on the various combinations with the currently available drugs are needed to improve the overall response rates. The simultaneous combination therapy with oral nucleoside and peginterferon alfa-2a from large-scaled randomized trials did not show a superior response rate over peginterferon alfa-2a monotherapy. Recently, sequential monotherapy with lamivudine for the first 4 weeks, followed by weekly peginterferon alfa-2a has shown favorable HBeAg seroconversion rate over peginterferon alfa-2a monotherapy, based on the assumption that early viral suppression by lamivudine can restore the immune function to facilitate the later immunomodulatory response by peginterferon alfa-2a. Furthermore, prior studies using 24 months of standard interferon alfa showed better ALT normalization and HBV suppression rates to 12 months of therapy. With the recent introduction of entecavir, the more potent oral nucleoside with few drug resistance, sequential monotherapy with entecavir can potently suppress HBV DNA with 4 weeks of treatment, which may facilitate the response of peginterferon alfa-2a to achieve HBV viral suppression. Therefore, we aimed to conduct a placebo controlled randomized control trial to evaluate if adding entecavir early in the course of therapy or extending the treatment duration of peginterferon alfa-2a can improve the treatment response.

The purpose of this study is to compare the immunogenicity and reactogenicity of the adjuvanted recombinant hepatitis B vaccine with that of Engerix™-B when both are injected according to a three dose schedule (0, 1, 6 months) in an adult non-responder population

During 1983-1990 in the Jiangsu province of China, 80,000 infants were randomised by area of birth between control, standard Hepatitis B vaccination (at 0, 1 and 6 months of age) and standard vaccination plus a booster dose at about 2 to 3 years of age. The aim is to prevent establishment of chronic HBV infection in early childhood, hence to prevent the morbidity of chronic hepatitis B in young adolescents and the incidence/mortality several decades later from liver cancer and other HBV related chronic liver diseases. Long-term follow-up through central registries will determine the impact of vaccination on liver cancer incidence and mortality.

Alcoholic liver disease has become one of the foremost causes of chronic liver disease across the world, and a cause of considerable morbidity and mortality. Alcoholic steatohepatitis is an entity in this broad spectrum, with severe alcoholic hepatitis transitioning to acute on chronic liver failure carrying a one month mortality of as high as 20 to 50%. The current management guidelines for severe alcoholic hepatitis show benefit with prolonged alcohol abstinence, nutritional support, the use of corticosteroids, pentoxifylline or N-acetyl cysteine (NAC) and early liver transplantation. However, major studies and meta-analyses have demonstrated that these interventions, with the exception of early liver transplantation, do not improve mortality rates to the level of statistical significance. Owing to the high short term mortality associated with severe alcoholic hepatitis, the inadequacy of a treatment that could significantly impact this short term mortality, and the limited applicability of early liver transplantation, a study on newer modalities of treatment is warranted. The role that human gut microbiota plays in health and disease is receiving considerable attention. Targeting intestinal dysbiosis, a phenomenon found to be intricately linked with the causation of alcoholic hepatitis, could provide insights into novel therapeutic strategies. Fecal microbiota transplantation is a novel approach that has gained widespread acceptance in in the management of recurrent severe Clostridium difficile infection. It's role is also being studied in other diseases where an association with gut dysbiosis has been found, such as in inflammatory bowel disease and irritable bowel syndrome. The role of FMT has also been studied in liver diseases such as non-alcoholic fatty liver disease (NAFLD), liver cirrhosis and primary sclerosing cholangitis. In this process, a diseased recipient is transferred fecal material containing the microflora of a healthy individual. It limits the colonization of pathogens, inducing colonization resistance, affects microbiota composition in the gut, as well as metabolism in the microbial pathogens. FMT helps alleviate gut dysbiosis and restores gut microbial diversity. Our aim is to evaluate the role of FMT on short term survival and improvement in scores of prognostic significance (CTP, MELD, MELDNa, mDF) in patients with severe alcoholic hepatitis.

Aim 1: The investigators will conduct a randomized controlled trial comparing two strategies to promote HCV screening, follow-up testing, and treatment among baby-boomers (i.e. persons born between 1945-1965): inreach with electronic medical record alerts and provider education vs. combination of inreach and provider education plus mailed outreach and patient navigation. Aim 2: The investigators will evaluate patient navigation strategies to promote follow-up testing and treatment evaluation among non-baby boomer Parkland patients (i.e. born before 1945 or after 1965) who are either: a) HCV antibody positive but have not completed follow-up viral load testing or b) HCV viral load positive and who have not completed in-clinic treatment evaluation.
