Plasma Citrate and Succinate Are Associated With Neurocognitive Impairment in Older People With HIV.

Neurocognitive impairment (NCI) is associated with monocyte activation in people with HIV (PWH). Activated monocytes increase glycolysis, reduce oxidative phosphorylation, and accumulate citrate and succinate, tricarboxylic acid (TCA) cycle metabolites that promote inflammation-this metabolic shift may contribute to NCI and slowed gait speed in PWH.Plasma citrate and succinate were assayed by liquid chromatography-mass spectrometry from 957...
