Faces of Frailty in Aging with HIV Infection

The number of adults who are aging successfully and have HIV infection is increasing. More effective antiretroviral therapy (ART) regimens are preventing individuals infected with HIV from reaching end stages of the HIV infection and developing AIDS (acquired immunodeficiency syndrome). However, even at lower viral loads, chronic HIV infection appears to have consequences on aging processes, including the development of frailty.

Frailty is a term used to describe vulnerability in aging. Frailty indices such as the Fried Frailty Index (FFI), the Veterans Aging Cohort Study (VACS) Index, and the Center for Epidemiologic Studies Depression scale (CES-D), an index of emotional frailty, associate with or predict clinical outcomes and death. However, even among existing frailty definitions, components require rigorous and consistent standardization. In the Women's Interagency HIV Study (WIHS), we have shown that frailty does not exist in isolation, even in midlife, and we use frailty to predict death. Frailty indices should be systematically used by health professionals to evaluate health and future risks for adverse events. Frailty prevention efforts, especially among those with HIV infection, appear to be essential for "successful aging" or aging without disability or loss of independence and may prevent HIV transmission. Taking care of elderly people is one of the major challenges of this century, and we must expect and be prepared for an increase in the number of aging adults, some of whom are patients with many co-morbidities and HIV infection.
