OBJECTIVES: To cross-sectionally describe brain alterations in PLHIV aged above
50 years old, receiving antiretroviral treatment (ART) and living in Senegal
compared to HIV-negative subjects.
METHODS: Twenty PLHIV and 26 HIV-negative subjects with comparable
socio-demographic and clinical characteristics underwent an MRI exam (3D-T1 and
FLAIR sequences). Global atrophy and White Matter Hyperintensities (WMH) were
evaluated. After assessing the feasibility and acceptability of MRI scans in this
population, we described atrophy and WHM prevalence and associated factors using
logistic regressions.
RESULTS: Overall, 43.5% of the study sample were aged ≥60 years, 58.7% were
women, and 28.3% had hypertension. The overall prevalence of atrophy and WMH was
19.6% [95% CI: 8.1-31.1] and 30.4% [95% CI: 17.1-43.7]. HIV status had no
significant effect on atrophy or WMH. Unemployment and hypertension were
significantly associated with atrophy, whereas women were less likely to present
atrophy. Aged ≥60 years was the only factor associated with WMH.
CONCLUSIONS: A high prevalence of atrophy and WMH was observed in West African
adults aged over 50 years without a clear HIV impact. As brain MRI studies are
critical to better understand cognitive and emotional outcomes, we encourage
those studies in older PLHIV in West Africa.
