from Program Abstract: HIV is a recognized risk factor for osteoporosis. The role of soluble markers and cellular immune parameters on HIV-related bone loss remains unclear.. We evaluated inflammatory markers and total hip bone mineral density (BMD) changes in a prospective HIV cohort enrolled during 2004-2006 (SUN Study)....74% undetectable viral load......Conclusions: In this healthy HIV adult cohort with predominantly controlled viremia, total hip BMD decline was associated with IL-6, replicative senescent T-cells, CCR5+ and tissue factor expressing monocytes. Memory CD4+ and CD8+ CD28+ T cells were associated with increases in BMD. Immunologic alterations that persist after virologic suppression may contribute to ongoing loss of BMD.
