Filter by:People with HIV infection who are taking antiretroviral therapy (ART) could be at risk for cardiovascular disease (CVD), which can be caused by inflammation. Methotrexate (MTX) is a medication used to treat inflammation in people with rheumatoid arthritis. This study evaluated the safety and effectiveness of low-dose methotrexate (LDMTX) at reducing inflammation in HIV-infected adults.
This pilot research trial studies factors affecting patient participation in Acquired Immune Deficiency Syndrome (AIDS) Malignancy Clinical Trials Consortium clinical trials. Determining how patients makes decisions about participating in a clinical trial may help doctors plan clinical trials in which more patients are willing to participate and are satisfied with their decision to participate.
The purpose of this study is to determine the safety, pharmacology and bioactivity of disulfiram in antiretroviral treated HIV-infected adults. The investigators primary hypothesis is that 3 days of disulfiram will result in an increase in HIV transcription in CD4+ T-cells in patients on suppressive antiretroviral therapy (ART).
Progressive HIV or HIV infection seems to be related to a preferential loss of CD4+ T lymphocytes, especially Th17+, within the mucosal intestinal lymphoid tissue, and with intestinal mucosal damage and bacterial product translocation, which correlates with the hyperactivation of the immune system, therefore with CD4+ T cell loss and prognosis. The objectives of this project are to investigate the correlation between the IL12/IL-23 imbalance and bacterial product translocation, and to study the polarization, infection or depletion of intestinal Th17 ex vivo. The investigators will test the effect of neutralizing anti-IL23 antibodies directed against p40, or less classically, anti- IL-23 p19.
The primary objectives of this study are to assess the safety of ABT-450/r/ABT-267 with and without ABT-333 coadministered with and without ribavirin (RBV) for 12 and 24 weeks in HCV GT1- or 4-infected participants with HIV-1 coinfection and to evaluate the percentage of subjects achieving HCV ribonucleic acid (RNA) < lower limit of quantification (LLOQ) 12 weeks following treatment.
This study is a double-blinded randomized controlled trial (RCT) to assess the efficacy of zinc supplementation vs. placebo among 250 HIV-infected Russians from the Russia ARCH Cohort, who are ART-naive at enrollment and have a recent history of heavy drinking.
Antiretroviral therapy (ART) can reduce HIV to very low levels in the blood, but it cannot cure HIV infection because a small amount of virus remains in cells as a hidden (latent) form. The purpose of this study was to evaluate the safety and efficacy of single dose and multiple dose administration of romidepsin (RMD) in HIV-infected adults.
We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We make it easy for patients to contribute to research for medical conditions that matter most to them, regardless of their location or ability to travel.
This study evaluated the effect of single doses of a magnesium/aluminum antacid (MAALOX) given 4 and 6 hours before or after administration of raltegravir, on the pharmacokinetics of raltegravir in human immunodeficiency virus (HIV)-infected participants. The study consisted of Part 1 (Periods 1, 2, and 3) and Part 2 (Periods 4 and 5), with each study period separated by a washout period of at least 2 days; Part 1 was separated from Part 2 by a Pause. Each study period had a duration of ≥2 days, and paused for evaluation of Part 1 pharmacokinetics results before continuing to Part 2. The same participants participated in Parts 1 and 2. The primary hypothesis tested (in Part 1) was that raltegravir plasma concentration 12 hours after administration (C 12 hrs) would not differ significantly from raltegravir C 12 hrs when antacid is administered 4 hours before or 4 hours after raltegravir.
In this study we will use a multi-modal imaging approach of MRS and fMRI to comprehensively assess the biological changes in the brain associated with EFV-based regimen (EFV/FTC/TDF), specifically alterations in the brain circuitry, function and local neurochemistry, and their correlation with neuropsychological function. In a cohort of HIV-infected patients who are clinically stable on the commonly use regimen of EFV/emtricitabine (FTC)/truvada (TDF) or Atripla, we propose to replace the EFV component with a new integrase inhibitor, elvitegravir (EVG) boosted with cobicistat (COBI), given as the EVG/COBI/FTC/TDF Single Tablet Regimen (STR) to evaluate the EFV-related neural alterations. This is a multidisciplinary study which involves a team of infectious disease experts in the field of HIV, neuroradiologists with expertise in fMRI and MRS techniques to study various central nervous system and psychiatric disorders and a psychiatrist with experience and expertise in research on abnormalities of affective and motivational processing in the context of neuropsychiatric disorders. We will utilize the established clinical research platform in the Infectious Disease outpatient clinical practice at the Brigham and Women's Hospital, where there is currently have many ongoing HIV-related studies and a large panel of HIV-infected patients motivated to be involved in clinically relevant research. We propose to use advanced neuroimaging to measure biologically changes in the brain associated with long-term EFV use with the following specific aims: 1. Determine changes in neurometabolites measured by MRS in the brain associated with long-term EFV use 2. Assess for alterations in neural activity correlated with affective symptoms associated with EFV vs STR use using fMRI, and their associations with changes in neurometabolites assessed by MRS, and with changes in cognition assessed by Trail Making and Digit Substitution Tests. 3. Determine changes in emotion, cognition and sleep quality after switching from EFV to STR, and how they correlate with subject treatment preference. This clinical study will extend our current understanding of EFV neurotoxicity by further defining the nature of these biological changes. Further elucidation of the neurobiological underpinnings of EFV-induced CNS toxicity will have clinical relevance in improving the quality of life and drug adherence of HIV-infected patients on ART, especially among older patients or those with baseline neuropsychiatric disorders, whom at baseline are more vulnerable to neurocognitive decline from long-term HIV infection.
