OBJECTIVE: To determine the prevalence of reduced bone mineral density (BMD) in a large female cohort of systemic lupus erythematosus (SLE) and to determine the role of steroids and disease related variables. METHODS: All females with SLE managed by rheumatologists affiliated with a single center were invited to undergo BMD measurement of the lumbar spine and left femoral neck by dual energy X-ray absorptiometry (DEXA), standardized examination, and medical record review. RESULTS: Ninety-seven females with a mean (SD) age of 44.2 (14.9) years were studied. Low bone mass [defined as BMD > 1 standard deviation (SD) below young adult mean] was present in 44.3 and 42.1% at the lumbar spine and femoral neck, respectively. Osteoporosis (defined as BMD > 2.5 SD below young adult mean) was present in 13.4 and 6.3% at the lumbar spine and femoral neck, respectively. Steroid usage showed a strong inverse relationship with BMD in the lumbar spine, but a less strong relationship in the femoral neck. CONCLUSION: The findings of high prevalence of reduced BMD and association with steroid therapy have important implications for the routine management of SLE.
