Background: Data on the relative contribution of HIV-infection to aging and age-related diseases remains inconclusive, and the total burden of disease has not been compared to other chronic diseases associated with premature aging. The purpose of this study was to investigate aging with HIV-infection and to compare it to aging with diabetes mellitus (DM) type 2 and aging without severe chronic disease.
Methods: This was a prospective multi-center cohort study evaluating differences in the total burden of disease between different groups of older patients (≥ 50 years). HIV-infected patients were compared to HIV-negative patients with DM type 2 and to a control group of patients without severe chronic disease. Physical constitution and activity, symptoms of aging, cardiovascular risk profile and comorbidities were analyzed. Clinical variables and patient questionnaires were assessed during 18 months follow-up.
Results: Among 761 participants (255 HIV, 249 DM, and 257 controls), weakness was most frequently found in HIV-infected patients. The perceived severity of symptoms of aging was significantly higher in patients with HIVinfection or DM than in the control group. Several comorbidities such as renal, neurological and cardiovascular disorders were more common in patients with HIV-infection or DM than in the control group. After adjusting for smoking and non-modifiable risk factors, the prevalence odds of a high cardiovascular risk remained markedly increased for patients with DM and, to a lesser extent, also for patients with HIV-infection. Malignancy incidence rates were highest in HIV-infected patients, followed by patients with DM and lowest in the control group.
Conclusions: This large cohort study in aging patients showed a considerable burden of disease associated with antiretrovirally treated HIV-infection as well as DM when compared to a control population without severe chronic disease – reflecting the need for specific prevention strategies and screening tools.
