We found that HIV+/HCV+ women had 7–8% lower areal bone mineral density (aBMD) by dual-energy x-ray absorptiometry (DXA) at the spine, hip, and radius (p < 0.01) and 5–7% lower volumetric BMD (vBMD) by central quantitative computed tomography (cQCT) at the spine and hip (p < 0.05). These data suggest that true deficits in vBMD may contribute to bone fragility and excess fractures reported in HIV+/HCV+ women.


aBMD by DXA is lower in persons coinfected with HIV and HCV (HIV+/HCV+) than with HIV monoinfection (HIV+). However, weight is often also lower with HCV infection, and measurement of aBMD by DXA can be confounded by adiposity; we aimed to determine whether true vBMD is also lower in HIV+/HCV+ coinfection.


We measured aBMD of the lumbar spine (LS), total hip (TH), femoral neck (FN), and ultradistal radius (UDR) by DXA and vBMD of the spine and hip by cQCT and of the distal radius and tibia by high-resolution peripheral QCT (HRpQCT) in 37 HIV+/HCV+ and 119 HIV+ postmenopausal women. Groups were compared using Student’s t tests with covariate adjustment by multiple regression analysis.


HIV+/HCV+ and HIV+ women were of similar age and race/ethnicity. HIV+/HCV+ women had lower body mass index (BMI) and trunk fat and were more likely to smoke and less likely to have a history of AIDS. In HIV+/HCV+ women, aBMD by DXA was 7–8% lower at the LS, TH, and UDR (p < 0.01). Similarly, vBMD by cQCT was 5–7% lower at the LS and TH (p < 0.05). Between-group differences in LS aBMD and vBMD remained significant after adjustment for BMI, smoking, and AIDS history. Tibial total vBMD by HRpQCT was 10% lower in HIV+/HCV+ women.


HIV+/HCV+ postmenopausal women had significantly lower spine aBMD and vBMD. These deficits in vBMD may contribute to bone fragility and excess fractures reported in HIV+/HCV+ women.
