High-risk alcohol consumption is associated with mitochondrial damage-associated molecular patterns in people living with HIV.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Alcohol (i.e., ethanol; EtOH) use disorders are common in people with HIV (PWH) and are associated with poor health outcomes. One potential reason for these poor health outcomes in PWH is that alcohol use is associated with mitochondrial damage and dysfunction, potentially leading to cell death. However, the link between alcohol use and mitochondrial functioning in PWH remains unclear. This study specifically investigated the relationship between high-risk alcohol consumption and mitochondrial damage-associated molecular patterns (mDAMPs) in PWH and people without HIV. We analyzed mDAMPs in 122 participants (51 HIV, 71 HIV-) before and after exposure to experimental pain testing to examine mDAMPs reactivity in response to noxious stress. Mitochondrial DAMPs were quantified from serum samples using real-time polymerase chain reaction, providing two variables: ND1 and ND6. High-risk alcohol consumption was assessed using the Alcohol Use Disorders Identification Test - C (AUDIT-C) questionnaire. In this study, we tested whether HIV status influenced the relationship between high-risk alcohol use and mitochondrial damage. Our findings revealed that PWH who engaged in high-risk alcohol consumption exhibited significantly increased mDAMPs following exposure to experimental pain testing for both ND1 (p = 0.045) and ND6 (p = 0.047). These results suggest that the effects of alcohol consumption on mitochondrial damage and dysfunction may be exacerbated by HIV infection. This study highlights the risk of high-risk alcohol consumption on mitochondrial health for PWH.
