Filter by:Objectives: 1. Primary objective: To Evaluate the rate of sustained virological response (SVR) of pegylated interferon alfa-2b (Peg-IFN) plus ribavirin (RBV) plus nitazoxanide (NTZ) in patients coinfected by HIV and HCV genotype 4 (HCV-4), never treated before (naïve) and with a treatment failure to a standard therapy with Peg-IFN plus RBV (experienced), and to compare it with the rate of SVR of these patients with Peg-IFN plus RBV is a historical cohort. 2. Secondary objectives: In naive, as well as in experienced patients: a) To evaluate the virological activity at weeks 4 and 12 after starting the combination of Peg-IFN plus RBV plus NTZ in HIV/HCV-4-coinfected patients. b) To analyze the safety of Peg-IFN plus RBV plus NTZ in HIV/HCV-4-coinfected patients. Design: Pilot clinical trial without control to evaluate efficacy and safety (phase II). Patients: Individuals with HIV infection and with confirmed chronic HCV infection. Treatment: NTZ 500 mg every 12 hours during 4 weeks, followed by NTZ 500 mg every 12 hours plus Peg-IFN plus weigh-adjusted RBV for 48 weeks. Total duration of therapy: 52 weeks. Primary variable: The proportion of patients with HCV RNA ≤10 IU/ml 24 weeks after finishing the programmed length of treatment. Secondary variables: 1. The frequency of individuals with HCV RNA ≤10 IU/ml 12 weeks after finishing the programmed length of treatment. 2. The proportion of patients with HCV RNA ≤10 IU/ml at 4 and 12 weeks after adding PegIFN plus RBV to NTZ. 3. The frequency of severe adverse events.
Atni-HBs to HBsAg and Anit-HBc was interpreted based on three hepatitis markers for clinical detection of HBV-infections. HBAg and Anti-HBs were negative and the Anit-HBc-positive referred to as Anti-HBc alone. When the Anti-HBc alone occurs, patients may be due to mutations in HBV HBsAg can not be detected due to (1), but if by the molecular diagnostics by polymerase chain reaction (PCR) technology can detect HBV DNA present. When Anti-HBc alone in patients with serum HBV DNA can be measured, then there may be occult HBV infection. In different countries, Occult HBV infection in the Anti-HBc Alone group had significant differences in the prevalence (2.9 ~ 22.8%) (2), but prevalence survey in Taiwan there are very few studies on this , It is hoped to be able to investigation the prevalence of occult HBV infection Among Anti-HBc Alone.
The rapidly progression of the disease in HIV-HCV co-infected patients justify the treatment. Combination of Peg interferon and Ribavirin is the best treatment because it improve the compliance of treatment. In APRICOT study genotypes 2 and 3 patients received 48 weeks and the rates of end of treatment response was 64% and the sustained virological response (24 weeks after the end of treatment) 62%. In mono-infected patients trials showed there are not differences in the sustained virological response between 24 and 48 weeks of treatment, however exit the doubt concerning the different kinetic viral in HIV-HCV co-infected patients and this could be related with a lost of profit with a shorter duration of treatment, only 24 weeks. In this study we woud like to evaluate if 24 weeks of treatment in HIV-HCV co-infected patients genotype 2 or 3 will have the same rate of clearance of virus at the end of follow-up period.
