<h3>Background</h3> Inflammatory arthritis is a risk factor for osteoporosis and it may be that treating systemic inflammation can improve bone mineral density (BMD). <h3>Objectives</h3> The aim of this study was to examine if DMARDs, steroids, and biologic therapies for rheumatoid arthritis (RA), psoriatic arthritis (PsA), psoriasis (PSO), and ankylosing spondylitis (AS) affect BMD. The aim of this study was to examine if DMARDs, steroids, and biologics for rheumatoid arthritis (RA), psoriatic arthritis (PsA), psoriasis (PSO), and ankylosing spondylitis (AS) affect BMD. <h3>Methods</h3> Medline, Embase, and Cochrane were searched from 1960 to present using English randomised controlled trials in adults. Review articles were excluded. Studies were grouped based on disease, treatment type, and site of BMD measurement (wrist, lumbar spine (LS), hip). ΔBMD were reported as standardized mean difference. <h3>Results</h3> 393 studies were identified; 13 were eligible (11 RA, 0 PsA, 0 PSO, 2 AS). For RA, significantly less wrist bone loss was seen with biologics (ΔBMD =0.27SD, 95% CI 0.07-0.47, P=0.009, I<sup>2</sup>=0%) and corticosteroids (ΔBMD =0.54SD, 95% CI 0.23-0.85, P=0&lt;0.001, I<sup>2</sup>=0%). Biologics had no significant effect on LS and hip BMD. Corticosteroids had more bone loss compared to placebo on LS (ΔBMD = -0.25SD, 95% CI -0.42 to -0.08, P=0.003, I<sup>2</sup>=52%) but no difference for hip. For AS, significant BMD increase was seen with biologics in both LS (ΔBMD = 0.98SD, 95% CI 0.73-1.23, P&lt;0.001, I<sup>2</sup>=16%) and hip (ΔBMD = 0.38SD, 95% CI 0.14-0.63, P=0.002, I<sup>2</sup>=0%). PsA and PSO could not be analyzed due to no suitable RCTs. <h3>Conclusions</h3> Based on our RA analysis, biologics and steroids were associated with less wrist bone loss (where synovitis is often present) but had no effect on BMD at the hip. Corticosteroids were associated with more bone loss in LS whereas biologics had no effect on BMD at the LS. For AS, biologics were associated with increase in both LS and hip BMD. <h3>Disclosure of Interest</h3> S. Siu Grant/research support: This study was supported by an unrestricted grant from AbbVie.
