The effect of glucocorticoids on bone mineral density in patients with rheumatoid arthritis: A systematic review and meta-analysis of randomized, controlled trials
Abstract
PURPOSE
The role of glucocorticoids in the treatment of rheumatoid arthritis (RA) is widely debated. Impairment of bone formation may be counter-balanced by reduced systemic inflammation. This review aims to assess the effect of prednisolone/prednisone on bone mineral density (BMD) in patients with RA analyzed in randomized, controlled trials.
METHODS
We performed a systematic literature search and identified randomized, double-blinded placebo-controlled studies including patients with RA and using prednisolone or prednisone as the intervention. We selected studies that measured BMD by DXA at baseline and at least once thereafter. Two authors independently performed reference review, data extraction and risk of bias assessment. Primary outcome was mean change in BMD from baseline to follow-up. Secondary endpoints included radiographic scores, RA disease activity indices and fractures. We rated the quality of evidence using the GRADE approach. Outcomes were standardized for meta-analyses and 95% confidence intervals (95% CI) were calculated.
RESULTS
We identified 7 studies and included previously unpublished data. Studies were similar regarding study population and intervention. Standard mean difference (SMD) in change in BMD from 0 to 24 months was -0.02 (95%CI -0.16, 0.12) at the lumbar spine and -0.11 (95% CI -0.25, 0.02) at the hip (both high quality evidence) between patients treated with prednisolone/prednisone or not. Data completeness was low in some studies,…
How strong is the evidence?
Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid.
