Plasma d-amino acids are associated with markers of immune activation and organ dysfunction in people with HIV.

Background: d-Amino acids (d-AAs) have been associated with age-associated conditions in the general population but their relevance in people with HIV (PWH), who experience accentuated/accelerated aging has not been studied. We compared d-AA levels in HIV-infected and uninfected controls and explored their association with markers of immune activation, gut permeability and organ dysfunction.

Design: Case-control analysis.
