Objective: Few data exist about the effect of dolutegravir (DTG) on bone mineral density (BMD) in real life. The aim of this study was to determine rates of change in BMD over time in people living with HIV (PLWH) treated with DTG. Design: The SCOLTA project is a multicenter observational study enrolling HIV-infected people who start newly commercialized drugs prospectively, with the aim of identifying toxicities and adverse events (AE) in a real-life setting. Methods: Dual-energy X-ray absorptiometry at the femoral neck (FN) and lumbar spine (LS) was performed at study entry (baseline, BL) and after 96 weeks. Percentage BMD change from BL was evaluated using a general linear model, including factors potentially associated with bone loss. Results: One hundred and sixty PLWH were enrolled (26.3% female, mean age 49.9 ± 11.2 years) from April 2015 to April 2017. Overall, we could calculate BMD change from baseline, for at least one site, in 133 subjects (83.1%). After a median of 102 weeks (IQR: 90–110), mean FN BMD increased, but not significantly, whereas LS BMD showed a significant mean increase of 13.1 (95% confidence interval, CI: 1.7–24.6) mg/cm3 (+1.6%, 95% CI: 0.3%, 2.8%) after a median time of 102 weeks (IQR: 84–110). As regards LS BMD, patients with osteopenia/ osteoporosis at study entry experienced a high increase from baseline (20.6, 95% CI: 3.1, 38.1 mg/cm3), as well as experienced subjects (16.9, 95% CI: 4.7, 29.2 mg/cm3) and those on vitamin D supplementation (26.8, 95% CI: 7.7, 45.9 mg/cm3). Conclusion: Dolutegravir-containing regimens could reduce the negative impact of antiretroviral therapy on bone, especially in patients with low BMD.

Abstract

Objective: Few data exist about the effect of dolutegravir (DTG) on bone mineral density (BMD) in real life. The aim of this study was to determine rates of change in BMD over time in people living with HIV (PLWH) treated with DTG. Design: The SCOLTA project is a multicenter observational study enrolling HIV-infected people who start newly commercialized drugs prospectively, with the aim of identifying toxicities and adverse events (AE) in a real-life setting. Methods: Dual-energy X-ray absorptiometry at the femoral neck (FN) and lumbar spine (LS) was performed at study entry (baseline, BL) and after 96 weeks. Percentage BMD change from BL was evaluated using a general linear model, including factors potentially associated with bone loss. Results: One hundred and sixty PLWH were enrolled (26.3% female, mean age 49.9 ± 11.2 years) from April 2015 to April 2017. Overall, we could calculate BMD change from baseline, for at least one site, in 133 subjects (83.1%). After a median of 102 weeks (IQR: 90–110), mean FN BMD increased, but not significantly, whereas LS BMD showed a significant mean increase of 13.1 (95% confidence interval, CI: 1.7–24.6) mg/cm3 (+1.6%, 95% CI: 0.3%, 2.8%) after a median time of 102 weeks (IQR: 84–110). As regards LS BMD, patients with osteopenia/ osteoporosis at study entry experienced a high increase from baseline (20.6, 95% CI: 3.1, 38.1 mg/cm3), as well as experienced subjects (16.9, 95% CI: 4.7, 29.2 mg/cm3) and those on vitamin D supplementation (26.8, 95% CI: 7.7, 45.9 mg/cm3). Conclusion: Dolutegravir-containing regimens could reduce the negative impact of antiretroviral therapy on bone, especially in patients with low BMD.
