Active clinical trials for "Hepatitis A"

The purpose of this trial is to determine if there is an improvement in the immune response of older adults over 50 years of age using a modified process hepatitis B vaccine and a currently licensed hepatitis B vaccine (RECOMBIVAX HB™).

To determine if there is an improvement in the immune response to HBsAg (hepatitis B virus) in healthy infants using a modified process in a combination Haemophilus Influenzae, type b/Hepatitis B vaccine and a currently licensed Haemophilus Influenzae, type b/Hepatitis B vaccine

Three dose primary vaccination study of reactogenicity and immunogenicity in healthy infants between 6-12 weeks of age at the time of the first vaccination against Streptococcus pneumoniae.

Approximately 50% of patients admitted for severe AH will have spontaneous improvement of liver function before initiation of therapy (ie decrease in mDF between hospital admission and initiation of steroids). These patients have a better prognosis than patients without spontaneous improvement of liver function. It has never been demonstrated that corticosteroids improve survival in severe AH patients with spontaneous improvement of liver function. Our hypothesis is that severe AH patients with spontaneous improvement of liver function represent a group who could most benefit from steroids

The study consists to Identify viral variants involved in the transmission of hepatitis C and characterize the antigenic and functional properties of their envelope glycoproteins at very early stage of infection (before seroconversion).

The aim of the prospective real-world study is to evaluate whether sequential combination therapy with pegylated interferon plus entecavir/tenofovir could induce higher rates of HBsAg loss in nucleoside-treated patients with chronic hepatitis B compared to continuous nucleoside treatment.

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.
