With advances in antiretroviral therapy, the life expectancy of HIV-infected individuals continues to improve with older individuals representing a rapidly growing proportion of those infected. However, despite improved life expectancy, substantial residual morbidity remains in treated HIV including increased rates of neurocognitive dysfunction, frailty, and cardiovascular disease. As these conditions also increase with normal aging, HIV is often thought to be a risk factor for "early" or "accelerated" aging. Prior studies have generally focused on HIV-specific factors and risk for neurocognitive dysfunction, frailty, and cardiovascular disease, while few have examined extensively risk factors found to be significant for these conditions in the general population.
The investigators hypothesize that the effects of age and HIV will be synergistic on the rates of non-AIDS morbidity. While the correlates and risk factors for non-AIDS morbidity in younger individuals may largely be related to HIV, in older individuals with sustained virologic control, traditional risk factors for neurocognitive disease, frailty, and cardiovascular disease will contribute more significantly to disease than HIV-specific risk factors. Our primary objectives are to:
- Define the prevalence and incidence of neurocognitive dysfunction, frailty, and cardiovascular disease in a well-defined cohort of aging virologically suppressed HIV-infected individuals.
- Identify correlates and risk factors for prevalent and incident neurocognitive dysfunction, frailty, and cardiovascular disease.
- Compare and contrast the identified correlates and risk factors for the co-morbidities of interest in older (>50 years old) and younger HIV-infected individuals.
