Alcoholic HepatitisThis study is designed to evaluate the hypothesis that patients with severe acute alcoholic hepatitis have lower morbi-mortality if the patients receive treatment with corticosteroids + NAC, compared to patients that only receive corticosteroids.

Follow up of IFN Vs DAAs HCV SVR (IFDACS Study)
Chronic Hepatitis C InfectionThe study is designed to provide long term clinical and virologic follow up in subjects infected with hepatitis C virus (HCV) who received interferon-based therapy or direct-acting antiviral agents (DAAs)-based therapy. This long term follow up study is observational and no treatment is provided for HCV infection.

HCV and Co-morbid Alcohol Use Disorders: A Translational Investigation of Antiviral Therapy Outcomes...
Hepatitis CAlcohol Use DisorderThe primary objective of this research project is to compare neuropsychiatric functioning, cortical activity, white matter integrity, and immune response among Veterans with and without alcohol use disorder (AUD), before and after direct-acting antiviral (DAA) therapy [a new treatment for chronic infection with the hepatitis C virus (HCV)]. Demographically-matched comparison groups of Veterans without HCV (HCV-, with and without AUD) will similarly be evaluated to determine the relative contribution of HCV and an HCV "cure" to outcomes putatively affected by alcohol abuse. Two specific aims are proposed. Aim 1: Determine the impact of DAA therapy and a sustained viral response on central nervous system (CNS) function. Aim 2: Evaluate the effects of AUD and unhealthy alcohol drinking on DAA therapy outcomes and CNS function. The information learned will address a critical gap in knowledge concerning the effects of alcohol use on DAA therapy outcomes and will help inform treatment guidelines that could be translated to clinical practice, such as targeted interventions to treat AUD in conjunction with HCV infection and follow-up strategies for patients who successfully complete DAA therapy but then need care for other potential CNS-related outcomes.

Hepatitis B Virus Infection in Immunized Children With HBsAg-positive Parents
Hepatitis b Virus InfectionHepatitis B virus (HBV) infection is a major public health problem facing the world, with more than 2 billion people infected with HBV. There are more than 400 million chronic carriers, and 75% of carriers live in the Asia Pacific region. The mother-to-child transmission route of hepatitis B virus is recognized as one of the most important routes of transmission, and recent studies have found that fathers who are carriers of HBV may also be one of the risk factors for HBV infection in children, but as far as the investigators know. Therefore, as a high-population area in China, the purpose of this study is to investigate the prevalence of HBV infection in this population.

Hepatitis B Virus Infection After Liver Transplantation in Children
Hepatitis B InfectionChina is a highly prevalent area of hepatitis B virus(HBV) infection, with at least 75 million hepatitis B virus carriers, and 80% of primary hepatocellular carcinoma (HCC) is associated with chronic hepatitis B virus infection. Liver transplantation is currently the preferred method for end-stage liver disease such as biliary atresia and cirrhosis in children. In recent years, children's liver transplantation has developed rapidly and the number of developments has increased significantly. If there is chronic hepatitis B virus infection in the donor liver, it may cause HBV transmission, or the patient may have a low-load occult hepatitis B virus infection, and after immunosuppressive treatment, it may lead to hepatitis B virus infection after surgery.

The Efficacy and Safety of Nucleos(t)Ide Analogues in the Treatment of HBV-related Acute-on-chronic...
Hepatitis BVirus Diseases1 moreHBV-related acute-on-chronic liver failure (ACLF) is a clinical syndrome defined as acute hepatic insult with diagnosed or undiagnosed chronic liver disease. Current clinical guidelines advocate oral antiviral treatment in HBV-related ACLF. However, no conclusion on which nucleoside analogue is the most satisfactory drug for the treatment of HBV-related liver failure has not been reached yet. In this cohort study, the investigators will compare the efficacy, safety, and tolerability of tenofovir alafenamide (TAF), Tenofovir Disoproxil Fumarate (TDF) and entecavir (ETV) in HBV-related ACLF in China. In addition, the drug metabolism characteristics of TAF will be explored in such severe liver injury population of HBV-ACLF.

Efficacy of Hepatitis B Vaccine Boosters Among Neonatally Vaccinated Children in Chongqing
Hepatitis B Vaccine Adverse ReactionWorldwide, hepatitis B virus (HBV) infection is a major cause of acute hepatitis, and chronic infection with HBV often leads to chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. So far, the most effective way to prevent HBV infection in susceptible population is to inject hepatitis B vaccine. However, long-term protection against hepatitis B virus (HBV) after vaccination remains widely debated. This study aims to carry out a comprehensive study to evaluate the efficacy of hepatitis B vaccine booster from the aspect of humoral and cellular immunity in neonatally vaccinated children in Chongqing.

Antiviral Prophylaxis and Infant Vaccination to Prevent Perinatal Hepatitis B Infection
Hepatitis BPregnancyMost new hepatitis B virus (HBV) infections are acquired perinatally. In this study, pregnant women with HBsAg and HBeAg will receive tenofovir disoproxil fumarate during the last trimester of pregnancy and for two months following delivery. Their infants will receive hepatitis B (HB) immunization, starting with a first dose soon after birth. We hypothesize that the risk of mother-to-child transmission of HBV will be lower than 2%. The results of the study will help define policy to manage HBV infected pregnant women to prevent perinatal transmission.

Hepatitis B Vaccination After Neonatal Surgery
Vaccination ReactionHepatitis B Virus Infection3 moreAt present, whether the hepatitis B vaccine (HBV) can be vaccinated on time after neonatal surgery has become a common problem for children's families, neonatal surgeons, and vaccination departments, but there are few relevant studies at home and abroad, and there is no corresponding guide or consensus. In the early stage, our research team investigated the vaccination plans of the vaccination units in the main urban areas of Chongqing for such children through telephone follow-up, and found that the practices of each unit were different, all based on their own experience, and there was no clear evidence to support the vaccination or should not be vaccinated, which may cause some children to miss the best vaccination time or increase the risk of vaccination. The center is a relatively large neonatal surgery center in southwest China. The diagnosis and treatment of neonatal digestive tract malformations is at the leading level in China. It can carry out various neonatal operations such as neonatal necrotizing enterocolitis, congenital anorectal malformations, and congenital megacolon. On average, it carries out more than 30 third and fourth grade neonatal gastrointestinal operations every month. It has accumulated a lot of experience in the follow-up of newborns, There is a large amount of clinical data support for children who need to be vaccinated after surgery, so it is planned to follow up the second and third doses of hepatitis B vaccine and whether there are adverse reactions related to vaccination for children who need to be vaccinated after gastrointestinal surgery in the neonatal period, and at the same time check the production of HBsAb after vaccination, The immune response and adverse reactions of hepatitis B vaccine at different time points after surgery were studied to increase clinical evidence for the determination of hepatitis B vaccine vaccination program for newborns after surgery.
