Insights
HIV-infected individuals face higher mortality and injury risks from alcohol use, even with treatment. Lower alcohol consumption limits are recommended for those with HIV.
Area of Science:
- Medical Research
- Public Health
- Infectious Diseases
Background:
- Individuals with Human Immunodeficiency Virus (HIV) may be more vulnerable to alcohol-related health issues than those without HIV.
- Antiretroviral therapy (ART) has improved outcomes for HIV-positive individuals, but co-occurring conditions like alcohol use disorders remain a concern.
Purpose of the Study:
- To investigate the differential impact of alcohol consumption on mortality and physiological injury in HIV-positive versus HIV-uninfected individuals.
- To determine specific alcohol consumption thresholds associated with adverse outcomes in both HIV-positive and HIV-uninfected populations.
Main Methods:
- Analysis of data from the Veterans Aging Cohort Study (VACS) including HIV-positive and HIV-uninfected participants.
- Utilized Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) scores and Cox proportional hazards models for mortality analysis.
- Employed linear regression models to assess physiological injury using VACS Index Scores, adjusting for covariates like age, race, smoking, and hepatitis C infection.
Main Results:
- The study included 18,145 HIV-positive and 42,228 HIV-uninfected individuals.
- Lower alcohol consumption levels (AUDIT-C score ≥4 or ≥30 drinks/month) were associated with increased mortality risk in HIV-positive individuals compared to HIV-uninfected individuals (AUDIT-C score ≥5 or ≥70 drinks/month).
- Physiological injury was linked to lower AUDIT-C scores in HIV-positive individuals (scores 5-7) versus HIV-uninfected individuals (score ≥8).
Conclusions:
- HIV-positive individuals experience greater mortality and physiological harm from alcohol use, even when on ART, compared to their HIV-uninfected counterparts.
- Recommended alcohol consumption limits should be lower for HIV-positive individuals to mitigate health risks.
- These findings underscore the importance of tailored alcohol use guidelines for vulnerable populations in HIV care.
Background:
HIV infected (HIV+) individuals may be more susceptible to alcohol-related harm than uninfected individuals.
Methods:
We analyzed data on HIV+ and uninfected individuals in the Veterans Aging Cohort Study (VACS) with an Alcohol Use Disorders Identification Test-Consumption AUDIT-C score from 2008 to 2012. We used Cox proportional hazards models to examine the association between alcohol exposure and mortality through July, 2014; and linear regression models to assess the association between alcohol exposure and physiologic injury based on VACS Index Scores. Models were adjusted for age, race/ethnicity, smoking, and hepatitis C infection.
Results:
The sample included 18,145 HIV+ and 42,228 uninfected individuals. Among HIV+ individuals, 76% had undetectable HIV-1 RNA (<500 copies/ml). The threshold for an association of alcohol use with mortality and physiologic injury differed by HIV status. Among HIV+ individuals, AUDIT-C score ≥4 (hazard ratio [HR] 1.25, 95% CI 1.09-1.44) and ≥30 drinks per month (HR, 1.30, 95% CI 1.14-1.50) were associated with increased risk of mortality. Among uninfected individuals, AUDIT-C score ≥5 (HR, 1.19, 95% CI 1.07-1.32) and ≥70 drinks per month (HR 1.13, 95% CI 1.00-1.28) were associated with increased risk. Similarly, AUDIT-C threshold scores of 5-7 were associated with physiologic injury among HIV+ individuals (beta 0.47, 95% CI 0.22, 0.73) and a score of 8 or more was associated with injury in uninfected (beta 0.29, 95% CI 0.16, 0.42) individuals.
Conclusions:
Despite antiretroviral therapy, HIV+ individuals experienced increased mortality and physiologic injury at lower levels of alcohol use compared with uninfected individuals. Alcohol consumption limits should be lower among HIV+ individuals.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
