General Inclusion Criteria:

  1. 21-60 years old;
  2. Able to speak and read English at least at 8th grade level;
  3. Alcohol use ≥.60 g/kg at least once in past year. In standard drinks, this amount translates to 1.9-3.0 drinks for an average-weight female and 2.4-3.9 drinks for an average-weight male.
  4. Body mass index of 18.5-34.9 kg/m2;
  5. Lab tests obtained in past year showing no evidence of acute/chronic Hepatitis B or C infection;
  6. HIV-1 serostatus (positive or negative, depending on group) confirmed by standard clinical testing;
  7. Able to consume soy and nuts safely (in order to consume the standardized meal).

General Exclusion Criteria:

  1. History of heavy drinking on a weekly or more frequent basis, with heavy drinking defined per NIAAA guidelines (≥4 drinks for women, ≥5 drinks for men on a given day), in the past two years;
  2. More than five heavy drinking episodes in past 90 days;
  3. Seeking or receiving treatment for alcohol/drug use, with exception of smoking cessation treatment;
  4. Antibiotic use in past 1 month;
  5. Daily use of non-steroidal anti-inflammatory drugs, which are known to increase gut permeability;
  6. Disorder of the lower GI tract (e.g., inflammatory bowel disease, ulcerative colitis);
  7. Positive urine test for amphetamine, cocaine, methamphetamine, opioids, or benzodiazepines (cannabis use will be assessed but is not an exclusion criterion);
  8. Positive screening for past 12-month drug use disorder, indicated by Drug Abuse Screening Test-10 score >2;
  9. Current major psychiatric disorder (current major depressive episode, bipolar disorder, psychotic disorder);
  10. History of fainting, weakness, infection, excessive bruising, or extreme distress from blood draw;
  11. Safety contraindication for MRI (e.g., metal implant); Note: copper intrauterine devices (IUDs) continue to be excluded due to Brown MRI research facility regulations but other non-metal IUDs are allowed;
  12. Head trauma with loss of consciousness >10 min;
  13. Inability to abstain from nicotine for 8 hours in-session;
  14. For cannabis users: inability to abstain for 48 hours prior to study;
  15. Pregnant, breastfeeding, or not using effective birth control;
  16. Any other clinical condition or therapy that, in the physician's opinion, would make subject unsuitable for study or unable to comply with dosing requirement.

HIV-Specific Inclusion Criteria:

  1. On antiretroviral therapy (ART) for ≥6 mos;
  2. Labs in past 6 mos showing viral load <100 copies/mL, hemoglobin ≥10.0 g/dL, neutrophil count ≥1,000 cells/μL, and platelet count ≥150,000/μL;
  3. No active AIDS diagnosis.

About this study

This study will examine whether moderate alcohol use in the context of HIV infection exacerbates inflammatory signaling in the immune system and brain. The study will recruit healthy individuals and people living with HIV infection who are otherwise in good health to participate. Participants will complete an experimental protocol that involves controlled alcohol administration and magnetic resonance imaging (MRI). Primary outcomes are plasma biomarkers of inflammation and MRI markers correlated with neuroinflammation. Results will advance understanding of the effects of alcohol use in people living with HIV infection.

Read the detailed description

A sample of 56 participants, to include equal numbers of people living with HIV and uninfected controls, will be recruited to complete the experimental protocol. Participants will be randomized to one of the two beverage conditions (0.60 g/kg alcohol beverage, 0.00 g/kg placebo beverage). Blood samples will be collected at baseline (prior to beverage administration) and for three hours afterward. Cognitive performance and subjective intoxication will be assessed using standardized measures. MRI scans will be collected 4-5 hours after beverage consumption to capture neurobiological outcomes on the descending limb of blood alcohol.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Plasma Biomarker of Microbial Translocation

    Lipopolysaccharide (LPS), measured in pg/ml

    Measured: 0-3 hours

  2. Plasma Biomarkers of Immune Activation

    soluble cluster of differentiation 163 (sCD163), measured in ng/ml

    Measured: 0-3 hours

  3. Cerebral Metabolites

    Magnetic resonance spectroscopy will be used quantify cerebral metabolites in brain regions of interest, specifically frontal lobe. Primary metabolites of interest include the summed peak of glutamate and glutamine; choline.

    Measured: 5 hours

  4. White Matter Diffusivity

    Diffusion-weighted MRI will be used to quantify diffusivity metrics in brain white matter. Primary outcome is fractional anisotropy (measured on a scale of 0-1, where 1 reflects total anisotropy).

    Measured: 5 hours

Secondary outcomes (2)
  1. Subjective Intoxication

    Intoxication rating scale (0-10), where a higher rating indicates greater subjective feelings of alcohol intoxication. Participants rate their maximum level of intoxication during the study.

    Measured: 0-5 hours

  2. Cognitive Functioning

    Repeatable Battery for Assessment of Neuropsychological Status standardized scores; Note: this measure was unable to be administered to due coronavirus (COVID-19) pandemic restrictions related to social distancing.

    Measured: 0-2 hours

Questions about this trial

What is this clinical trial studying?

A study testing Alcohol, ethyl, moderate dose in people with HIV-1-infection and Alcohol Drinking, run by Brown University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 17 Dec 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Plasma Biomarker of Microbial Translocation (time frame: 0-3 hours). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Dec 2025.
