Periarticular and generalised bone loss in patients with early rheumatoid arthritis: influence of alendronate and intra-articular glucocorticoid treatment. Post hoc analyses from the CIMESTRA trial

Objectives The aims of this study were to investigate the influence of alendronate and intra-articular betamethasone treatment on bone mineral density (BMD) changes in hand, lumbar spine and femoral neck during 1 year of a treat-to-target study (Cyclosporine, Methotrexate, Steroid in RA (CIMESTRA)). Patients and methods A hundred and sixty patients with early, active rheumatoid arthritis (RA) received methotrexate, intra-articular betamethasone and ciclosporin /placebo-ciclosporin. Patients with Z-score ≤0 also started alendronate 10 mg/day. BMD of the hand (digital x-ray radiogrammetry (DXR-BMDhand)), BMD of lumbar spine and femoral neck (dual x-ray absorptiometry (DXA-BMDlumbar spine and DXA-BMDfemoral neck)) and x-rays of hands, wrists and forefeet (modified Sharp-van der Heijde score) were measured at baseline and 1 year, with complete data available in 107 patients. Results The change in BMD in hand, lumbar spine and femoral neck was negatively associated with the dose of intra-articular betamethasone (p
