Fracture Risk with Modified FRAX in Men Living with HIV

Abstract

Background: Aging of the HIV-infected population and prolonged use of ARTs, produced metabolic alterations, including increased fracture risk. FRAX is a validated, computer-based clinical fracture risk calculator which estimates 10-year risk of major fracture, and hip fracture. However may underestimate risk in HIV-infected individuals. Several experts recommend considering HIV a cause of secondary osteoporosis.Methodology: Were included 52 men living with HIV, classified as high, moderate and low risk using ABRASSO graphic tool.Results: High risk prevalence found for major fracture and hip fracture were both 2 (4.2 %) using FRAX; while 10 (20.8 %) and 14 (29.2 %) using modified FRAX, respectively. Considering bone densitometry, 5 (12.8 %) were high risk for hip fracture and was noticed an increase in high risk major fracture from 4.2 % with FRAX to 5.1 % with FRAX considering bone densitometry. As for the low risk, 19 (39.6 %) for major fracture and 23 (47.9 %) for hip fracture with FRAX. While low risk modified FRAX were 0 (0 %) for major fracture and 8 (16.7 %) for hip fracture. It was also evidenced an association of high risk for major fracture and hip fracture with modified FRAX using Fisher's exact test [p=0.0273 (bilateral)].Conclusion: It was concluded is recommended using modified FRAX for people living with HIV for better control and therapeutic decision-making about osteometabolic alterations provocated for the virus and ARTs.
