Frailty, Geriatric Syndromes and Care Pathways of Older Adults Living With HIV in West Africa

With currently available antiretroviral therapy, people living with HIV (PLWHIV) are living longer. This exposure to HIV and combination antiretroviral therapy may accelerate the aging of this population, thus increasing the prevalence of premature frailty.

There are few data on the prevalence of frailty and geriatric syndromes among older people living with HIV (OpHIV) in sub-Saharan Africa (SSA) and the screening and diagnostic tools to identify them.

The initiation contract financed by the ANRS-MIE in 2021 whose objective was to 1) carry out an inventory and evaluate the feasibility of a project for monitoring OpHIV in Burkina-Faso in Côte d'Ivoire and Togo and 2) to select the collection tools adapted to the description of geriatric syndromes in these elderly people has allowed to highlight the following (i) The collection of data on geriatric conditions and syndromes is almost non-existent in the daily care and management practice (ii) there is a significant proportion (10,6%) of PLWHIV aged 60 years and over in the active files of the PLWHIV care centers that participated in the survey (iii) Adapted screening tools have been selected and will allow documentation of the above-mentioned syndromes. This research project, which follows on from this initiation contract, will therefore make it possible to obtain data from the geriatric evaluation, to identify the specificities of PLWHIV by comparing them to a population not infected with HIV and to propose geriatric management adapted to PLWHIV. Its innovative nature also lies in its mixed approach combining quantitative and qualitative methods, which will make it possible to document the needs and resources for the care of PLWHIV in a global and holistic manner.

600 participants, aged 60 years and over (300 living with HIV and 300 not living with HIV), in three West African countries (Burkina Faso, Côte d'Ivoire, Togo) will be included in this study whose primary objective is to compare the prevalence of frailty among people aged 60 years and over (PA60) between HIV-infected and non-HIV-infected; the secondary objective is to estimate the prevalence of frailty among PA60 according to HIV status. A population-based matching will be performed on sex and age class (threshold 70 years), during the recruitment of HIV- PA60.

This will be a mixed study combining:

• A "clinical" component comprising a stratified, comparative, international, multicenter cross-sectional study;
• A "health systems strengthening" component combining a quantitative cross-sectional survey and a qualitative survey;
• A qualitative socio-anthropological component including individual interviews and focus groups with people living with HIV60, their families and caregivers.

The 3 components will be conducted with a time lag between the different components due to the overlapping constitution of the source populations.

Most research on aging with HIV in the context of SSA has been very clinically focused (e.g., frailty or cognitive impairment). This research will provide a more comprehensive approach that takes into account the different levels of factors influencing health (individual, health system, social environment).
