Filter by:The purpose of this study was to assess the safety, tolerability, pharmacokinetics and antiviral activity of ABT-333 (also known as dasabuvir) in treatment-naïve, hepatitis C virus (HCV)-infected participants.
This proposed pharmacokinetic study will test the hypothesis that in critically ill patients with respiratory failure requiring mechanical ventilation such as might be anticipated to be needed to treat patients with severe influenza pneumonia, oseltamivir administered enterally via nasogastric tube, with and without concomitant food or alimentation, will have similar oral bioavailability to that observed in ambulatory adults ill with influenza in whom oseltamivir therapy 75 mg BID is efficacious and well tolerated. Additionally, this experiment will test the hypothesis that increasing the dose (150 mg), with and without concomitant enteral feeding, will show a proportionate increase in bioavailability. Relative oral bioavailability will be assessed from plasma concentration vs. time over 12 hrs and urinary recovery of drug from 0 to 48 hrs after administration.
This study will demonstrate the immunogenicity and evaluate the safety/tolerability of the vaccine in Chinese children between 12 and 23 months of age.
For chronic HBV infection, an optimal pharmacological agent to promote recovery from chronic HBV infection would be one that inhibits HBV DNA polymerase, combined with the clearence from the liver of cccDNA to block HBV reactivation after the circulating viral burden has been eliminated by therapy. The activity of clevudine on cccDNA in combination with its potent antiviral activity on HBV polymerase makes it the optimal agent in combination with tenofovir for this protocol.
Study Purpose: The purpose of this study is to assess that Liquid Acupuncture(Herb Acupoints Injection) Therapeutics could achieve permanent efficacy response in Chronic Hepatitis B. Efficacy Assessment: At cessation of the Treatment(about at 24 weeks)comparing Testing Data with the Normal Criteria and their individual baseline.Continue for monitoring the Status 1-5 years. Data Analysis: Each 4 weeks collecting Patients' testing data and fill a table.A summary table will be presented as frequency tables for categorical variables as number or percentage.
This study of neurotropic viral infection and Tuberculous CNS infection is the comprehensive investigation of CSF PCR arrays (Hybrydiaztion technique,Sybergreen and Taqman real time PCR arrays of CSF ) in suspected cases of viral CNS infection, Tuberculous CNS infection in both AIDS and non AIDS patients. Patients with clinical viral encephalitis and all meningoencephalitis including all patients with HIV/AIDS CSF and non AIDS will be banked and test for RNA and DNA viral sequence by Real time PCR arrays and IS6110 gene of Mycobacterium tuberculosis. Clinical data and final diagnosis will be used to analyze the result of this PCR arrays technique compared to clinical gold standard criteria.
While immunisation of school-age children against influenza is not recommended in Hong Kong, past experience in Japan and elsewhere suggests that immunisation of children may protect the wider community through its indirect transmission-limiting impact as well as the direct immunologic protection afforded vaccinated children themselves. We aim to assess whether vaccinating children against influenza protects vaccinees as well as their household contacts from infection.
Chronic liver disease are characterized by increased levels of plasma IL-6, but the bioactivity of this cytokine in this disease is not well known. IL-6 receptor complex is regulated by multiple receptors subunits: the soluble form of IL-6 Receptor enhance IL-6 signal by a process called trans-signaling on cells expressing few membrane IL-6 receptors. Soluble gp130 is the natural inhibitor of IL-6 trans-signaling. The aim of this study is to characterize circulating and liver levels of theses compounds of IL-6 receptor complex, to unravel the bioactivity of IL-6 in this disease.
Through a prospective observational cohort study enrolling patients newly diagnosed with Human immunodeficiency virus (HIV): Aim 1: Assess attitudes and beliefs about HIV disease and care over time and relate those attitudes and beliefs to success in following the Steps of HIV Care. Aim 2: Validate a simple visual analogue scale for assessing adherence to highly active antiretroviral therapy (HAART) in patients newly starting HAART in routine care. Aim 3: Implement latent growth curve analysis for modeling changes in attitudes and beliefs over time, and for assessing the impact of the components of the Steps of HIV Care model on health outcomes.
The purpose of this study is to determine whether raltegravir 400 mg b.i.d. in a boosted PI regimen is as efficacious and safe as the NRTI backbone in a boosted PI regimen.
