Osteoporotic vertebral fracture (VF) and osteonecrosis of the femoral head (OFH) are major concerns in patients with systemic rheumatic diseases treated with high-dose glucocorticoids (GCs). The investigators examined and compared the incidence and risk factors of VF with those of OFH in patients who had recently received high-dose GC therapy to clarify the relationship between these two complications.

A: etidronate

Detailed Description:

Patients with rheumatic diseases receiving GCs (≧0.5 mg/kg/day for prednisolone equivalent) within the past 2 months were enrolled in this study, and treated with 200 mg/day of etidronate cyclically. The bone mineral density (BMD) of lumbar spines (L2-4) was examined by QDR2000. OFH was evaluated by magnetic resonance imaging (MRI). identifier: NCT00679978.

Forty-four patients completed the 2-year study including annual X-rays and the BMD analysis. MRI evaluation at entry and 2 years was performed in 41 patients. The BMD values with anteroposterior (AP) and lateral views decreased by 6.4% and 9.7% respectively in the first year, but were stable in the second year. Eleven patients developed VF and 9 patients developed OFH. The risk factors for VF included previous VF and a low BMD value (T score < -1.5) of AP view at baseline with odds ratio (OR) 14.9 (95%CI 2.9-76.4), while the risk factor for OFH was the recent maximum GC dosage (>1.2 mg/kg/day versus ≦; OR=7.7, 95%CI 1.3-45.5) and the decrease in BMD value of lateral view (>15% versus ≤; OR=6.7, 95% CI 1.2-36.1) in the first year.
