Popis: The objective of the study was to assess the effects of HIV infection and antiretroviral therapy on change in bone mineral density (BMD) in postmenopausal minority women.We report a longitudinal analysis of change in BMD with a median duration of 15.4 (interquartile range 13.1, 20.7) months in a prospective cohort study of 128 (73 HIV+, 55 HIV-) postmenopausal Hispanic and African-American women.Annualized change in BMD by dual-energy x-ray absorptiometry and correlation with baseline markers of bone turnover and serum levels of inflammatory cytokines were measured.HIV+ women were younger (56 ± 1 vs. 59 ± 1 yr, P0.05) and had lower body mass index (BMI; 28 ± 1 vs. 31 ± 1 kg/m(2), P0.01). The majority of HIV+ women were on established antiretroviral therapy for more than 3 yr. At baseline, BMD, adjusted for age, race, and BMI, was lower in HIV+ women at the lumbar spine (LS), total hip, and radius and serum C-telopeptide was higher. Annualized rates of bone loss adjusted for baseline BMD were higher in HIV+ women by 2.4-fold at the LS (-1.2 ± 0.3% vs. -0.5 ± 0.3%, P = 0.0009), 3.7-fold at the one third radius (-1.1 ± 0.2% vs. -0.3 ± 0.2, P = 0.006) and 1.7-fold at the ultradistal radius (-1.2 ± 0.2% vs. -0.7 ± 0.2%, P = 0.02). In multivariate analysis, HIV+ status predicted bone loss at the LS, total hip, and ultradistal radius. Among HIV+ women, lower BMI, higher markers of bone turnover levels, and tenofovir were associated with more bone loss.HIV+ postmenopausal minority women had lower BMD, increased bone turnover, and higher rates of bone loss than HIV- women. These features may place these women at increased risk for fracture as they age.
