Insights
For HIV patients with alcohol problems, any alcohol use significantly reduces adherence to antiretroviral therapy. Abstinence is linked to better treatment adherence, improving health outcomes.
Area of Science:
- Public Health
- Infectious Diseases
- Addiction Medicine
Background:
- Alcohol abuse is a known factor linked to poor adherence to highly active antiretroviral therapy (HAART).
- This study focuses on HIV-infected individuals with a history of alcohol problems, examining varying levels of alcohol consumption's impact on HAART adherence.
Purpose of the Study:
- To determine the relative importance of different levels of alcohol consumption on HAART adherence.
- To investigate the association between alcohol use patterns and treatment adherence in a specific HIV-positive population.
Main Methods:
- Longitudinal study surveying 349 HIV-infected persons with a history of alcohol problems over 30 months.
- Assessed HAART adherence and alcohol consumption (none, moderate, at risk) via interviews.
- Utilized multivariable longitudinal regression models to analyze the relationship between alcohol consumption and adherence, controlling for confounders.
Main Results:
- Alcohol consumption was the most significant predictor of HAART adherence (p < 0.0001) in 267 patients on HAART.
- Recent alcohol abstinence was associated with significantly better adherence compared to moderate or at-risk alcohol usage.
- Odds ratios indicated substantially higher adherence with abstinence versus at-risk (3.6) or moderate (3.0) use.
Conclusions:
- Any alcohol consumption among HIV-infected individuals with a history of alcohol problems is linked to poorer HAART adherence.
- Interventions addressing alcohol use may improve antiretroviral adherence and enhance overall clinical outcomes for this patient group.
Background:
Alcohol abuse has been associated with poor adherence to highly active antiretroviral therapy (HAART). We examined the relative importance of varying levels of alcohol consumption on adherence in HIV-infected patients with a history of alcohol problems.
Methods:
We surveyed 349 HIV-infected persons with a history of alcohol problems at 6-month intervals. Of these subjects, 267 were taking HAART at one or more time periods during the 30-month follow-up period. Interviews assessed recent adherence to HAART and past month alcohol consumption, defined as "none", "moderate", and "at risk". We investigated the relationship between adherence to HAART and alcohol consumption at baseline and at each subsequent 6-month follow-up interval using multivariable longitudinal regression models, while controlling for potential confounders.
Results:
Among the 267 HIV-infected persons with a history of alcohol problems who were receiving HAART, alcohol consumption was the most significant predictor of adherence (p < 0.0001), with better adherence being associated with recent abstinence from alcohol, compared with at-risk level usage (odds ratio = 3.6, 95% confidence interval = 2.1-6.2) or compared with moderate usage (odds ratio = 3.0, 95% confidence interval = 2.0-4.5).
Conclusions:
Any alcohol use among HIV-infected persons with a history of alcohol problems is associated with worse HAART adherence. Addressing alcohol use in HIV-infected persons may improve antiretroviral adherence and ultimately clinical outcomes.

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.
