Abstrakt: Background: Osteoporosis and vertebral fractures (VFs) are frequently observed in males living with HIV (MLWH). While bisphosphonates seem effective on bone mineral density (BMD) in MLWH, data on VFs are lacking. In this real-life longitudinal study performed on 118 MLWH (median age 53) who were followed-up for a median of 7 years, we aimed to evaluate the long-term efficacy of oral bisphosphonates on VFs in MLWH. Methods: The inclusion criteria were age >18, stable HIV infection, bisphosphonate-naïve, blood samples from the same laboratory, and three densitometries and morphometries performed with the same densitometer. Results: At baseline, VFs were detected in 29/118 patients (24.6%). Patients with VFs were older (p. 0.042), had longer HIV infection duration (p. 0.046) and antiretroviral exposure (p. 0.025), and demonstrated higher luteinizing hormone levels (LH, p. 0.044). Of the 29 patients with VFs at inclusion, 11 developed new VFs, of which 8 were under oral bisphosphonates (p. 0.018). Among the 89 without basal VFs, 11 developed VFs, of which 2 were under oral bisphosphonates. Patients with a worsened bone condition (regarding BMD and/or new VFs, n. 32) had more frequently high LH levels (>9.4 mIU/mL, p. 0.046) and higher HCV co-infection compared to patients with a stable bone condition (p. 0.045). It should be noted that 38.6% of patients discontinued oral bisphosphonates due to medical indication or personal choice, and 14.0% never started them. Conclusions: In conclusion, we found that oral bisphosphonates were not completely effective in preventing VFs, especially in patients with VFs at baseline; this is probably due to the multifactorial pathogenesis of fragility fractures in this population. A poor adherence to treatment and attention to gonadal function are also important issues in this population. [ABSTRACT FROM AUTHOR]
