Filter by:Oral antiviral drugs which can be given to patients with HBeAg-positive chronic hepatitis B include Lamivudine, Clevudine, Adefovir, Telbivudine, Entecavir and Tenofovir. 2009 American Association for the Study of Liver Disease (AASLD) Treatment Guidelines and 2009 European association for the Study of the Liver (EASL) Treatment Guidelines recommend the administration of Entecavir or Tenofovir with high potency and low resistance. Lamivudine has low antiviral potency and high incidence of mutation in long-term administration compared to Entecavir or Tenofovir. Clevudine causes the elevated creatinine kinase (CK), side effects including myositis/myopathy and much mutation in the long-term administration. Globe study demonstrated Telbivudine had more excellent antiviral potency than Lamivudine, which was also comparable to or higher than Entecavir or Tenofovir. Nevertheless, the choice of treatment drugs can be limited due to the mutation rate of 25% for 2 years. However, the analysis of Globe study results showed that 2-year treatment progress was very good in patient who showed virologic response at 24 weeks after the initiation of treatment and that high antiviral potency and low mutation rate were observed when the Telbivudine roadmap strategy (in the event that virologic response is shown at 24 weeks, telbivudine monotherapy is maintained and in the event that virologic response is not shown, tenofovir add-on therapy is done) recently implemented and announced in 2011 Asian Pacific Association for the Study of the Liver (APASL) was applied. However, the study was single arm study, which restricted the comparison between Entecavir and Tenofovir monotherapy groups. Therefore, this study intends to compare the anti-viral effect and mutation rate between Entecavir 0.5mg monotherapy group and Telbivudine roadmap strategy group in patients with HBeAg-positive chronic hepatitis B through a randomized study.
This 4-year project will be guided by a biobehavioral model for the study of exercise interventions in two phases with the purposes to : 1. explore the patients' physical activity preferences and develop doable activity lists during treatment period 2. examine the changes of health-related physical fitness component over interferon treatment 3. develop the Personalized Physical Activity and Psych-Education (PPAPE) Program and test its effects on decreasing fatigue, physical and psychological distress, and improving their health-related physical fitness and quality of life in patients with chronic hepatitis C receiving Interferon with Ribavirin Combination Therapy 4. evaluate the outcome of the PPAPE program on increasing adherence to therapy, the sustained virological response (SVR) in 24 weeks after the end of treatment, and the time-consuming for education program during intervention.
The aim of this study is to investigate the off-treatment sustained virological and biochemical response in chronic hepatitis B patients following the guideline by the Asian Pacific Association for the Study of the Liver (APASL) in Korea.
1. Adefovir add-on therapy is superior to switching to adefovir monotherapy or entecavir 1mg monotherapy for chronic hepatitis B (CHB) patients with lamivudine resistance (LAM-R) 2. Long-term adefovir add-on therapy was effective for viral suppression. However, the economic burden for such dual antiviral therapy is heavy because of infinite treatment. 3. Tenofovir disoproxil fumarate (TDF) is a potent antiviral agent. TDF demonstrated potent antiviral efficacy in a subset of lamivudine experienced HBeAg-positive patients. TDF is also superior to ADV in HBeAg-negative and HBeAg-positive treatment-naive patients. 4. Theoretically, TDF can replace LAM/ADV when viral suppression has been achieved by LAM/ADV combination treatment in LAM-R CHB patients.
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.
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).
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.
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.
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.
