Filter by:This study is conducted among people aged 18-50 in Dandong City, an area with a high incidence of hepatitis A in recent years. 1000 qualified pariticipants with signed informed consent will be screened for anti-HAV antibodies by collecting blood sample of 3ml. One dose of hepatitis A vaccine will be administrated to all the pariticipants. Negative anti-HAV antibodies-negative subjects will recieve the second dose of hepatitis A vaccination, and 400 of them will be randomly selected and assigned to 4 groups with different interval of vaccination(6 month, 18 months, 36 months and 60 months). Blood samples will be collected before vaccination of each dose and on 28 days after each dose of vaccination to anti-HAV antibody test. Safety data will be collected within 28 days after each vaccination with a smartphone mini-program.
This is an open-label, randomized study to investigate subcutaneous (SC) bepirovirsen when delivered via SC injection from vial or Prefilled syringe fitted with a Safety syringe device (PFS SSD) in healthy adult participants. The aim of this study is to provide relative bioavailability data to support the transition from the vial presentation of bepirovirsen, to a ready-to-use liquid in a PFS SSD when both are given by a health care professional. The study will also assess self-administration using the PFS SDD, and the safety and tolerability of bepirovirsen.
Elimination of mother-to-child-transmission (EMTCT) of HIV, syphilis and hepatitis B are key priorities in Indonesia, the fourth most populous country in the world. Despite national guidelines and strong antenatal care attendance, coverage of antenatal screening for these diseases among pregnant women remains extremely limited in Indonesia. The Indonesian government is committed to improving the integration of HIV/syphilis/hepatitis B testing and treatment into the antenatal platform but currently lacks comprehensive evidence on interventions to support this. We will evaluate a low-cost and locally driven intervention based on the principles of continuous quality improvement to strengthen antenatal care and promote screening for HIV, syphilis and hepatitis B. Continuous Quality Improvement (CQI), which involves local antenatal care (ANC) teams systematically collecting and reflecting on local data to inform the design and implementation of service delivery, has been effectively used to strengthen ANC in a number of Sub-Saharan African countries but yet to be comprehensively evaluated in ANC services in Indonesia. This approach holds considerable promise for Indonesia, a highly populous and diverse country where a 'one size fits all' approach to the delivery of quality ANC rarely applies.
The aim is to assess the efficacy and specific safety in an observational study of patients with Chronic hepatitis D (CHD) with prospective follow-up, with antiviral treatment of 2 mg Bulevirtide (BLV) +/- PEG-IFNα-2a and +/- NA given as part of the patient's routine medical care. Also, explorative endpoints of biomarkers in peripheral blood, saliva, fecal sample and/or intrahepatic markers/signatures, and quality of life outcomes will be assessed.
This is a non-interventional retrospective multi-center study for the patients received Entekavir or TDF for Hepatitis B prophylaxis.
Hepatitis C diagnostic devices have been developed at the University of Hull to detect and quantify the Hepatitis C virus in patients' plasma and serum samples. This study aims to test the new point-of-care devices that are designed to be low cost and user-friendly. Excess, stored, HCV patients' plasma, serum and blood samples will be supplied by the Virology laboratory (Hull University Teaching Hospital's Trust; HUTH). These samples were taken and analysed as part of patients' clinical monitoring, and are stored prior to disposal in the Virology laboratory. The proposed study will use the samples in a fully anonymised manner.
Two hundred and ninety-six million people worldwide are chronically infected with the hepatitis B virus (HBV), with around 750,000 deaths each year linked to the development of cirrhosis or hepatocellular carcinoma. Current treatments based on nucleoside analogues (NA) achieve virological cure in only 5% of cases at 10 years. The virological persistence of HBV is explained by the persistence of cccDNA (covalently-closed circular DNA) in the nucleus of hepatocytes. Complex and poorly understood interactions between immunological and virological responses explain the persistence of ccccDNA. A better understanding of the immunological and virological interactions of the intrahepatic compartment during chronic HBV infection is needed to better understand the mechanisms of viral persistence and for research and development of new drugs to achieve the goal of a functional cure for HBV (defined as the prolonged loss of Hepatitis B surface antigen (HBsAg) after cessation of treatment, associated with a decrease in intrahepatic cccDNA or its transcriptional inactivation). The intra-hepatic compartment can be explored by liver biopsy. A fine needle aspiration (FNA) technique is used to characterize primary hepatic tumors, with fewer complications than liver biopsy. One study has validated its use for immunological exploration of the intra-hepatic compartment. Finally, a recently published study confirms a correlation between FNA and liver biopsy virological markers in patients with chronic HBV infection. However, no combined immuno-virological study has been carried out to explore this intra-hepatic compartment by FNA in patients with chronic HBV infection. The investigators will assess the intrahepatic compartment of patients chronically infected with HBV (+/- hepatitis Delta (HDV)) to understand the mechanisms of viral persistence and characterize host immune responses to HBV. These investigations will make it possible to determine the immuno-virological profiles of patients who would benefit from intensification of antiviral treatment or, potentially, discontinuation of antiviral therapy.
Establishment and validation of the non-invasive model to predict antiviral therapy in the gray zone of chronic hepatitis B
Find a possible association between Fibronectin type Ⅲ domain containing protein 5 \ Irsin (FNDC5 rs3480) gene single nucleotide polymorphism with chronic hepatitis B and the distribution of its alleles, in relation to many clinical parameters of the chronic hepatitis B group. - Asses the correlation between IL-35 serum level and the risk of chronic hepatitis B. - Asses the correlation between SOD serum level and the risk of chronic hepatitis B.
At 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.
