- OBJECTIVE: Hormone replacement therapy (HRT) is known to exert a positive effect in preventing bone loss and a beneficial effect on the disease activity in rheumatoid arthritis (RA). We evaluated the effects of HRT on bone mineral density (BMD) and on the course of established RA. METHODS: Eighty-eight postmenopausal women with RA were randomly allocated to receive HRT, vitamin D3, and calcium supplementation or vitamin D3 and calcium supplementation alone for 2 years. The effects of additional HRT on laboratory and clinical measures of disease activity, quality of life, and BMD and on radiographic joint damage were investigated. RESULTS: Treatment with HRT suppressed signs of inflammation as shown by reduction in erythrocyte sedimentation rate (ESR) (p = 0.025) and an elevation in hemoglobin concentration (p = 0.007), a better clinical outcome assessed by response on the Disease Activity Score 28 (DAS28) (p = 0.036), increased BMD in the forearm, proximal femur and spine (p < 0.01), and retarded (p = 0.026) progression of joint destruction among patients with radiological progressive disease. No significant effect on quality of life was seen. CONCLUSION: Two years of HRT in women with active RA had significant ameliorating effects on inflammation, DAS28 response, and BMD and was associated with slower progression of radiological joint destruction. The mechanisms by which HRT exerts its effects remain to be elucidated. We suggest HRT can be used in addition to conventional therapy in the management of postmenopausal patients with RA.

- OBJECTIVES: To investigate determinants of joint destruction and reduced bone mineral density (BMD) in postmenopausal women with active rheumatoid arthritis (RA) not treated with bisphosphonates or hormone replacement therapy and to evaluate if there are common markers of erosive disease and bone loss. METHODS: BMD was measured using dual x ray absorptiometry and joint damage was examined by x ray examination according to the Larsen method in 88 patients with RA. Associations between BMD and Larsen score, and between demographic and disease related variables, including proinflammatory cytokines, HLA-DR4 epitopes, and markers of bone and cartilage turnover, were examined bivariately by simple and multiple linear regression analyses. RESULTS: 49/88 (56%) patients had osteoporosis in at least one site. Reduced BMD and increased joint destruction were associated with: at the forearm and femoral neck, high Larsen score, low weight, and old age (R(2)=0.381, p<0.001; R(2)=0.372, p<0.001, respectively); at the total hip, low weight, high Larsen score, and dose of injected glucocorticosteroids (R(2)=0.435, p<0.001); at the lumbar spine, low weight, reduced cartilage oligomeric matrix protein, and increased carboxyterminal propeptide of type I procollagen (R(2)=0.248, p<0.001). Larsen score was associated with long disease duration and increased C reactive protein (CRP) (R(2)=0.545, p<0.001). CONCLUSIONS: Osteoporosis is common in postmenopausal patients with RA. Low weight and high Larsen score were strongly associated with BMD reduction. Increased CRP and long disease duration were determinants of erosive disease in postmenopausal women with RA. These findings indicate common mechanisms of local and generalised bone loss in RA.
