Active clinical trials for "HIV Infections"

This is a 48 week study to explore the pathogenesis of HIV treatment related bone disease by using a novel imaging technique, 18F-Fluoride Positron Emission Tomography (18F-PET/CT), which measures regional bone formation. The study will include other standard methods (serum bone markers and DXA) for comparison. Patients enrolled will have baseline, week 24 and week 48 assessment, with baseline being the date of replacing tenofovir disoproxil fumarate (TDF) in their HIV treatment regimen with tenofavir alafenamide fumarate (TAF), compared to a control group continuing TDF. Allocation to change to TAF or continue TDF will be randomised to allow an unbiased assessment of bone changes.

The purpose of this plot study is to find out the relationship between metabolic changes and anti-retroviral therapy (ART), life style and clinical conditions of HIV-infected patients using nuclear magnetic resonance (NMR) based systems biology approach and metabolomics methodology.

Raltegravir is the first marketed strand-transfer inhibitor of HIV-1 that was FDA approved in 2007. It is currently one of the preferred treatment regimens for HIV by the Department of Health and Human Services. It has become a widely used antiretroviral therapy option for HIV infected patients. It provides good tolerability and a favorable lipid profile for patients when compared to some other antiretroviral treatment options. Little data is reported about efficacy in a minority patient population. Moreover, data in an indigent minority population in the United States has not been aggregated before. Therefore this study will investigate the efficacy of raltegravir in minority women residing in Houston, TX who are HIV infected.

Magnetic resonance spectroscopy (MRS) is commonly applied in medicine with 1H proton or 31-phosphorus spectra. The proton MRS is often used in evaluating the central nervous system and 31P MRS is used in muscular diseases or neoplasms. However, the proton MRS is also considered to be applied to the musculoskeletal system because of its profound amount of protons. Ballon used the STEAM technique, and Schick used the PRESS technique, to investigate the lipid and water spectra of the bone marrow and also correlated those with hematological diseases and post-treatment effects. Schellinger et al. used the STEAM sequence to calculate the lipid content of the vertebral bone marrow and found that it was influenced according to age and sex. The investigator had used the proton MRS to evaluate the lipid and water spectra of the femoral head and revealed its significance in predicting avascular necrosis of the femoral head. According to the above research literature, the investigators considered further investigation of the proton MRS in evaluating the musculoskeletal system.

The purpose of this study is to test an interactive multimedia informed consent (iMIC) computer program to see if the program can generate a consent form that potential participants in an HIV trial can understand. This study will also determine if these participants prefer the computer-generated consent form and associated interactive tools to a standard consent form written by researchers. Study hypothesis: 1) Participants who receive information about clinical trials from iMIC Consent Tutorials will answer more questions about the trial correctly than participants who receive information about clinical trials from standard paper consent forms. 2) Participants will rate the iMIC Consent Tutorials as having better usability and user satisfaction than standard paper consent forms.

MATCH is an observation study of HIV-infected adults on effective antiretroviral therapy (ART) and demographically matched uninfected adults to evaluate muscle and aging.

The objective of the antiretroviral treatment is to inhibit the viral replication, estimated(appreciated) by the measure of the viral plasmatic load(responsibility). In this inhibition of the viral replication usually joins an immune reconstruction [ 1 ]. Nevertheless, a viro-immunological dissociation, i.e. an undetectable viral load(responsibility) and an absence of immune reconstruction, is regularly observed. It is now turned out that an undetectable viral load(responsibility) does not correspond to the total absence of viral replication and that it is possible to detect of the intracellular pro-viral DNA . Raltegravir ®, because of its mode of action(share) inhibiting the integration of the pro-viral DNA in the chromosomes of the infected cells(units) , could decrease the intracellular reservoir of monocyte-macrophages, improve the homeostasis, so optimizing the cooperation lymphocytes T - macrophages. Several experimental data suggest that the regression of the abnormalities of cellular interactions, and the rate of apoptose abnormally raised(abnormally brought up) by cells(units) T at the patients in viro-immunological dissociation, could be obtained . This study aims at measuring the impact of Raltegravir ® on the viral reservoirs lymphocyte and monocyte, to quantify the expression of the molecules of costimulation, the source(spring) of intercellular interactions lymphocytes - monocytes, and to measure the rate of apoptose of the cells(units) T.

To assess the HIV resistance rate to variable antiretroviral agents in Taiwan, especially in patients with treatment failure, and to know the correlation between the drug resistance pattern and the HIV subtype, we will enroll a total of 150~200 HIV-1-infected subjects to perform genotypic resistance testing and try to establish facility of phenotypic resistance testing.

This study aims at correlating TNF-α, INF-γ, IL-2, IL-4, IL-10 and TGF-β values as dosed by ELISA and mRNA expression by real-time PCR with histopathological hepatic biopsy findings in individuals with HIV/HCV coinfection. This population will be divided into three groups (G1: with no HAART; G2: with detected HIV viral load (HIV VL); G3: with undetected HIV VL), which will be then compared to two control groups with monoinfection by HIV or by HCV, in addition to a third control group comprising normal blood donors.

The purpose of this study is to evaluate the efficacy and tolerability of DAA-based regimens in the clinical practice in HIV/HCV-coinfected patients. Hypothesis: The efficacy and tolerability of DAA-based regimens in the clinical practice is different to what is observed in clinical trials in HIV/HCV-coinfected patients.
