OBJECTIVES: Collagen vascular diseases requiring treatment with high-dose glucocorticoids are frequently complicated by vertebral fracture. We investigated the incidence of symptomatic vertebral fractures for 20 yr among patients who were treated with high-dose glucocorticoids in the Chiba-Shimoshizu Rheumatic Cohort. METHODS: A total of 2631 patients with collagen vascular diseases (aged >or=18 yr) was registered between 1986 and 2006. The prevalence of symptomatic vertebral fracture was compared between the high-dose glucocorticoid group newly treated with high-dose glucocorticoids (>or=20 mg/d prednisolone equivalent) (n = 700), and the non-glucocorticoid controls not treated with glucocorticoids (n = 194). RESULTS: During the 20-yr study period, symptomatic vertebral fractures occurred more frequently in the high-dose glucocorticoid group (23.9%) than in the non-glucocorticoid controls (2.6%). According to a Kaplan-Meier analysis, the cumulative incidence of symptomatic vertebral fracture was significantly higher in the high-dose glucocorticoid group than in the non-glucocorticoid controls (P < 0.001). Stratified into age quartiles of the high-dose glucocorticoid group (age 18-31, 32-47, 48-59, and 60-88 yr), the patients had a markedly increased incidence of symptomatic vertebral fracture with aging. The hazard ratios were also significantly higher in the older age quartile of 60-68 than in the younger age quartile of 32-47 (P < 0.001 for trend). The hazard ratio was 26-fold higher in patients aged 60-88 than in patients aged 18-31 (P < 0.01). In the group with fractures, the treatment duration before fracture was negatively associated with the initial age (r = -0.6587; P < 0.001). CONCLUSIONS: The prevalence of symptomatic vertebral fractures was higher in the patients treated with high-dose glucocorticoids than the untreated controls. Vertebral fractures were age dependent in patients treated with high-dose glucocorticoids. Treatment duration before fracture incidence was significantly shorter in the older patients.
