Tenofovir disoproxil fumarate (TDF) is a critical component of first-line antiretroviral regimens for HIV worldwide. However, TDF-containing regimens have been associated with decreased bone mineral density and increased fracture risk, which may in part be mediated through secondary elevations in parathyroid hormone (PTH). Prior cross-sectional data suggest vitamin D binding protein (DBP) levels may increase with TDF exposure leading to a functional vitamin D deficiency, which...

Introduction: Lower bone mineral content (BMC) has been reported in HIV-infected children, as well as those on ritonavir-boosted lopinavir (LPV/r)-based antiretroviral therapy (ART). Older studies of children with HIV report increased bone resorption, but data with current antiretroviral regimens are limited.Methods: This analysis presents data from the CHANGES Bone Study (Johannesburg, South Africa). Whole body (WB) BMC was assessed by dual-energy X-ray...
