The HIV, Adipose Tissue Immunology, and Metabolism Study
NCT04451980 · View on ClinicalTrials.gov ↗
Study Summary
With the introduction of effective anti-retroviral therapy (ART), HIV-infected persons can now survive for decades, but this success has been accompanied by an increased risk of developing metabolic disease and diabetes in HIV-infected persons compared to the general population. Recent studies from HIV-negative subjects have identified several associations between circulating immune cell populations and impaired glucose tolerance, including increased activated CD4+ and CD8+ T cells, and reduced regulatory T cells. Of note, these same changes in peripheral T cell subsets are frequently observed in patients with chronic HIV infection. The goal of this study is to assess whether the circulating T cell distribution is reflective of the adipose tissue T cell distribution, and to understand whether chronic adipose tissue T cell activation may impair adipocyte (i.e., fat cell) function and insulin sensitivity. If the investigators' hypotheses are correct, this will demonstrate that chronic peripheral immune activation (i.e., high memory T cells, low naïve cells, and increased expression of activation surface markers) is associated with greater adipose-resident CD4+ and CD8+ T cell expression of activation markers, adipose tissue inflammation, and insulin resistance.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04451980
The ClinicalTrials.gov registry entry for NCT04451980 describes a study currently listed as active not recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 172 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Vanderbilt University Medical Center, which has 695 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Diabetes Mellitus, Type 2 appearing as the primary indexed condition, and to 4 interventions — of which CT scan is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04451980 reports 1 study location spanning 1 distinct geographic area — top geographies include Tennessee. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
