Cognitive impairment and frailty predict mortality in people with HIV who inject drugs, independent of other factors. Targeting cognition, frailty, and inflammation may improve aging outcomes.
Area of Science:
- Gerontology
- Neuroscience
- Infectious Diseases
Background:
- Cognitive impairment and frailty are common in aging populations, particularly among people living with HIV (PLWH).
- Limited research addresses cognitive function determinants and the interplay of cognition, frailty, and mortality in people who inject drugs (PWID) with or at risk for HIV.
- Understanding these factors is crucial for improving health outcomes in this vulnerable group.
Purpose of the Study:
- To investigate the determinants of cognitive function in PWID with and without HIV.
- To examine the relationship between cognitive function, frailty, and mortality in this population.
- To explore the association between cognitive function and inflammation.
Main Methods:
- Cognitive assessments and frailty evaluations (Fried criteria) were conducted in the AIDS Linked to the IntraVenous Experience (ALIVE) cohort.
- An inflammatory index was derived from IL-6 and soluble TNF-α receptor-1 levels.
- Cox proportional hazards models were used to analyze mortality risk.
Main Results:
- Older age and hazardous alcohol use were linked to poorer cognitive function (processing speed, motor, global).
- Reduced cognitive function (processing speed, motor, global) and frailty independently predicted increased mortality.
- Cognitive deficits were associated with heightened inflammation.
Conclusions:
- Cognitive impairment is a significant, independent predictor of mortality in PLWH who are PWID, irrespective of frailty or HIV status.
- Interventions addressing cognitive function, frailty, and inflammation may enhance aging outcomes for PLWH and PWID.

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.
