Abstract:
Background:Patients with rheumatoid arthritis (RA) are at an increased risk of osteoporosis and vertebral fractures. This study aimed to investigate factors associated with vertebral fractures and treatment goals to prevent new vertebral fractures in patients with RA.
Methods:The database used in this study included outpatient data of RA patients at the authors’ hospital of RA patients taken from 2018 to 2022. The patients underwent annual imaging evaluations to assess parameters, including bone mineral density of the lumbar spine (LS; L2-4), total hip, and femoral neck, as well as vertebral fractures. Vertebral fractures were evaluated using radiographic images of the T8 to L5 vertebrae.
Results:The prevalence rates of new vertebral fractures in 2018–2019, 2019–2020, 2020– 2021, and 2021–2022 were 2.0%, 1.3%, 2.3%, and 2.0%, respectively. The presence of existing vertebral fractures was associated with new vertebral fractures (p=0.003; odds ratio, 0.241; 95% confidence interval, 0.093–0.624). The cut-off T-score values for the LS for new vertebral fractures in patients with or without pre-existing vertebral fractures were -0.7 (sensitivity, 40.9%; specificity, 100%) and -1.4 (sensitivity, 69.0%; specificity, 62.5%), respectively.
Conclusions:The presence of pre-existing vertebral fractures is an independent factor associated with new vertebral fractures. It is important to tailor treatment goals based on the presence or absence of vertebral fractures to effectively prevent new fractures.
