The higher risk of osteoporosis and fracture associated with HIV infection and certain antiretrovirals has been well established and the need for risk stratification among older adults increasingly recognized. This review focuses upon emerging data on bone complications with HIV/HCV coinfection, in children and adolescents, and with pre-exposure prophylaxis (PrEP), as well as new management strategies...
Summary Ritonavir (RTV) is a commonly used antiretroviral associated with bone loss. We show that peripheral blood mononuclear cells (PBMCs) from human immunodeficiency virus (HIV)-positive women on RTV are more likely to differentiate into osteoclast-like cells when cultured with their own sera than PBMCs and sera from HIV− women or HIV+ on other antiretrovirals. Introduction RTV increases differentiation...
High-resolution peripheral quantitative computed tomography (HR-pQCT) is a promising in vivo imaging technique that can be used to assess the three-dimensional microstructure of the radius and tibia. Micro finite element models can also be constructed from these images to estimate the mechanical competence of these sites, giving this technique the potential in the clinical diagnosis of osteoporosis...
