Filter by:Despite effective ART that can suppress both HIV and HBV, HBV-related liver disease remains a significant co-morbidity in this population. Little is known about the histologic spectrum of liver disease, the significance of complete vs. incomplete HBV suppression, the utility of novel virologic and serum markers of disease severity, and the long-term renal and bone effects of TDF-based therapy. This proposal will address these important questions and impact the science and health of those coinfected with HBV-HIV.
This is a study to show that vaccination with three doses of Quinvaxem presented in Uniject is not inferior to vaccination with three doses of Quinvaxem presented in single dose vials, with respect to protection against all antibodies (anti-hepatitis B surface antibodies, anti-polyribosyl ribitol phosphate (PRP), anti-diphtheria, anti-tetanus and anti-Bordetella pertussis) one (1) month after completion of the 6-10-14 week vaccination course.
This is a multicenter, double blind, active-controlled, randomized, parallel group study to demonstrate the anti-viral activity and safety of Baracle Tab. and Baraclude Tab. for patients with HBeAg Chronic Hepatitis B. The subject will receive two tablets daily for 48 days.
The purpose of this study is to compare the liver toxicity in HIV-infected patients with chronic hepatitis B and/or hepatitis C, who start a new antiretroviral drug regimen, as well as the influence of the degree of pre-existing liver fibrosis on the incidence of liver toxicity.
To evaluate and compare the immunogenicity of Eutravac (Diphtheria-Tetanus-acellular Pertussis [DTaP] Hepatitis B [HB] combined) vaccine with separate but simultaneous administrations of DTaP and HB vaccine each administered to healthy infants, as measured by seroprotection/vaccine response rates 4-8 weeks post-final immunisation.
In the UK, infants currently receive a 5-in-1 vaccine (Pediacel) at 2, 3 and 4 months of age, which protects against diphtheria, tetanus, pertussis (whooping cough), polio and Haemophilus influenzae type b (Hib). Infants also routinely receive a meningococcal group C vaccine (MenC) at 3 and 4 months and a 13-valent pneumococcal vaccine (Prevenar13) at 2 and 4 months of age. This study aims to offer infants a 6-in-1 vaccine (Infanrix-Hexa)that also helps protect against hepatitis B alongside the other routine vaccinations in the UK infant immunisation schedule and assess their immune responses to the different vaccines. Hepatitis B virus infects the liver and usually affects adults, but children can be infected through close contact with carriers of the virus. Children with hepatitis B infection may not have symptoms for many years but may go on to develop liver failure, cirrhosis and cancer. Many other countries already use Infanrix-Hexa and this study is being undertaken to help decide whether the UK can do the same. Babies taking part in this study will receive Infanrix-Hexa instead of Pediacel. All other vaccines given will be the same as in the routine schedule but will include one MenC vaccine instead of 2 doses because the UK infant immunisation schedule is soon going to change so that all babies will receive only one MenC vaccine at 3 months of age. There are currently several licensed MenC vaccines that can be given to babies. In order to check whether there are differences in protection, babies taking part will randomly receive one of 3 MenC-containing vaccines: NeisVacC, Menjugate or Menitorix. Studies have already shown that one dose of Neis-Vac or Menjugate given to babies at 3 months provides similar protection against MenC infection as two doses given at 3 and 4 months. Menitorix protects against both Hib and MenC, so babies in the group receiving MenitorixTM will have an extra dose of Hib which is also included in Infanrix-Hexa but might have a lower antibody response to MenC compared to the other two MenC vaccines, although all infants should be well-protected after their 12-month booster vaccinations, which also contain Menitorix.
Patients with spontaneous decline of HBV DNA were non-randomly assigned to accept peginterferon alfa-2a or entecavir therapy, or didn't accept any antiviral regiment.
The purpose of this study is to investigate the efficacy and safety of medical ozone in treatment of chronic hepatitis B patients.
The objective of this clinical trial is to compare the response rate obtained with two different vaccination schemes against HBV in cirrhotic patients. These patients must be candidates for liver transplantation, who have failed seroconversion (anti-HBs < 10 IU/ml) after three intramuscular doses of 40 µg.
The project goal is to conduct a randomized controlled trial (RCT) to test whether mobile phone short message system (SMS) reminders, either with or without mobile-phone based travel subsidies will improve timeliness, coverage, and drop-out rates of routine EPI vaccines in rural western Kenya.
