Filter by:In order to study the immunotherapeutic effects of electroporation (EP)-mediated dual-plasmids Hepatitis B Virus DNA vaccine, the investigators plan to conduct a double-blind, randomized, placebo-controlled trial, approved by Chinese State Food and Drug Administration with written informed consent from each chronic hepatitis B (CHB) patients with baseline ALT more than 2 times the ULN, for whom antiviral treatment is indicated and who were under the simultaneous lamivudine (LAM) chemotherapy.
Hepatitis B is a form of liver disease caused by a DNA-virus, called hepatitis B virus (HBV). Infection can result in an inflammation of the liver parenchyma with various clinical manifestations ranging from an asymptomatic course to jaundice. After contact with the virus the immunological response of the host determines the clinical outcome leading to either viral clearance or a chronic infection. Although several factors are responsible for the development of chronic HBV-infection, one of the factors is a weak and transient CD8+ T-cell responses after HBV infection. In chronic hepatitis B, inflammation can lead to scarring which is the driving force to fibrosis and cirrhosis. Some immunological parameters, like a newly discovered subset of IL-17 producing T helper cells (Th17 cells), may influence the disease progression of HBV. In the cirrhotic patient, eventually there is an increased risk of hepatocellular carcinoma (HCC) leading to liver failure. Recent literature in Asian patients with chronic hepatitis B showed that serum HBV viral load is a strong predictor for the development of cirrhosis, independent of hepatitis B e- antigen status and serum alanine transaminase level. It is unclear whether these results can be extrapolated to non-Asian (Caucasian and African) populations because of differences in host (HLA background) and viral (HBV genotype) factors. The aim of this study is to elucidate the question whether historic HBV viral load is associated with the risk of HBV-related cirrhosis or mortality in a cohort of non-Asian individuals with chronic hepatitis B infection.
The cohort of post-menopausal women represents a group of very-difficult-to-treat patients in whom a more powerful approach is required in order to improve the disappointing response rate. Thus the addition, in patients with previous failure to PEG/RBV treatment or in naïve patients, of a powerful drug like Boceprevir could greatly improve SVR rate as suggested by the results of SPRINT_2 trial in whom Boceprevir addition determined a 30% improvement in SVR rate in difficult gt 1 patients of African descent versus standard PEG IFN/Ribavirin therapy or by those of RESPOND-2 that showed the same percent improvement of RGT-retreatment with Boc/P/R of previous failure of standard therapy. Goal of the study is to verify whether the addition of a 24-week treatment with boceprevir to standard antiviral therapy with Peg IFN and ribavirin will increase the rate of SVR in patients difficult to treat, such as HCV-positive women in post-menopausal women with genotype 1, not only those who have never been treated, but also in those who have not responded to previous treatment with peginterferon and ribavirin (Riba).
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 ⅲ. The rate of serum HBV DNA < 300 copies/mL - The rate of ALT normalization ⅴ. The rate of HBsAg loss ⅵ. The rate of serum HBV DNA < 10,000 copies/mL
Patients with HCV genotype 1 and IL28B CC Polymorphism who have a rapid virological response to treatment are randomised to either 24 or 48 weeks HCV treatment. Our hypothesis is that there is no important difference in effect between the two treatment effect.
An observational study will be performed in subjects aged 3-65 years old to describe the dynamic changes of cellular immunity after vaccination of hepatitis B vaccine, and to find out the expression levels of Th9 cells and IL9 in subjects with different response to the primary immunization (3 single -dose injunctions).
The investigators will evaluate the efficacy of high dose vitamin C in chronic hepatitis patients whose serum liver enzymes are elevated more than upper limit.
Despite the availability of effective anti-tuberculosis agents that exist to treat this illness, hepatotoxicity during first-line drugs anti-tuberculosis medications (ATT) such as isoniazid (INH), rifampin (RIF), and pyrazinamide (PZA) is not uncommon and limit their use. There is no consensus on method of the reintroduction of anti-TB medications. The risk of reintroducing of a anti-TB medications could be hazardous. There are several differences between the guidelines from the ATS, BTS and the Task Force of the European Respiratory Society, the WHO and the International Union Against Tuberculosis and Lung Disease about the methods of reintroducing of anti-TB medications. The investigators plan to do a prospective study to evaluate the outcome and safety of reintroduction of anti-TB medications after resolution of hepatitis during anti-TB treatment among TB patients in the investigators hospital.
Antiviral treatment on Chronic Hepatitis B (CHB) patients with liver cirrhosis is compulsory and effective. Telbivudine, which is superior to lamivudine in the treatment of CHB,is considered to be appropriate for the antiviral treatment on CHB patients with liver cirrhosis.
This is a multi-center cohort study in which the Real-time Tissue Elastography® measurements will predict prospectively the incidence of hepatocellular carcinoma, the incidence and severity of gastroesophageal varices ascites and decompensated cirrhosis in hepatitis B or C patients.
