Filter by:Counseling intervention: Primary objective: to evaluate and compare, in at-risk populations, the efficacy of three different counseling methods in terms of propensity to come back for a HIV re-test. Secondary objectives: to evaluate and compare the efficacy of the counseling methods in terms of reported risk behavior and HIV knowledge as well as their acceptability and cost-effectiveness; describe the distribution of duration from HIV primary infection to detection; and estimate the prevalence of chronic hepatitis B and C, and syphilis in HIV-uninfected participants of targeted populations. Reminder intervention Primary objective: to evaluate and compare, in at-risk individuals who require frequent testing, the efficacy of reminders in terms of propensity to come back for a HIV re-test within 7 months. Secondary objective: to assess the cost-effectiveness of reminders. The interim analyses have shown that that some strategies are better than the others and the Advisory Committee recommended to use only the most efficient strategies (Computer assisted counseling and Scheduling an appointment and sending reminder to clients). In addition, CD4 cell count normal ranges in 30 HIV uninfected individuals in Thailand will be assessed. Transient elastometry (FibroScan) will be used to assess liver fibrosis in participants with and without viral hepatitis.
This is a Phase 2, open-label,randomized, multiple dose, varied administration regimen study with 2 parts (Parts A and B) in Subjects Infected with Chronic Hepatitis B Virus
The hypothesis of this investigation stresses that the current understanding of the prevalence of HCV infection in the general population and in different subgroups will serve to lay out medium- and long-term measures for action geared toward reducing the disease burden through preventive, research, screening and therapeutic measures. Aim: To determine the prevalence of seropositivity and chronic infection with the HCV and to analyze the associated factors. To analyze and infer different screening strategies for HCV infection based on the at-risk groups/cohorts of elevated prevalence detected. to assess the efficiency of screening strategies and the subsequent cost-effectiveness of treatment in the general population
Treatment cessation in chronic hepatitis B is associated with high rates of disease relapse. However patients who achieve the seroclearance of hepatitis B surface antigen (HBsAg) (<0.05 IU/mL) show good off-treatment durability after treatment cessation. Through the quantification of HBsAg, the study aims to investigate how low should quantitative HBsAg be before once can achieve successful disease control after treatment cessation.
The purpose of this study is to assess the efficacy and safety of ABT-493/ABT-530 in adults with chronic hepatitis C virus genotype 1-6 infection and human immunodeficiency virus-1 co-infection.
This study will evaluate the efficacy and safety of 48-week treatment with pegylated interferon (PEG-IFN) alfa-2a (Pegasys) monotherapy in participants with chronic hepatitis D (CHD). Treatment will be followed by 24 weeks of treatment-free follow-up.
This study aimed to evaluate the efficacy of different hepatitis B vaccination regimens in HIV-infected adults with low CD4 cell count in northern Thailand.
This single-center, randomized, open-label, pilot study is designed to evaluate the efficacy and safety of 48 weeks of treatment with peginterferon alfa-2a alone versus in combination with ribavirin in participants with CHD.
The REP 201 protocol is a small exploratory study assessing the antiviral effects and tolerability of REP 2139-Ca when used with a full course of pegylated interferon (48 weeks) in treatment naive patients or in patients already receiving entecavir and continuing entecavir with treatment.
Participants with CHC and normal ALT, who have been under treatment with peginterferon alfa-2a and ribavirin for at least 4 weeks, will be enrolled into this non-interventional, open-label study. The primary aim is to evaluate quality of life according to the Short Form 36 (SF-36) questionnaire, modified for the Greek population.
