  • Title: [Osteoporosis in rheumatoid arthritis].
    Author: Haugeberg G.
    Journal: Tidsskr Nor Laegeforen; 1997 Feb 20; 117(5):651-4. PubMed ID: 9102954.
    Abstract:
    In cases of rheumatoid arthritis, osteoporosis may be local or general. The aetiology is multifactorial. Reduced bodily function, synovial inflammation, steroids and menopause are important risk factors. Studies have shown that, in cases of primary osteoporosis, bone mineral density measurements in the distal radius may predict risk of fracture at other sites, such as the neck of the femur and the dorsal vertebrae. Such a connection is not found for rheumatoid arthritis. Bone density measurements in the distal radius may overestimate the risk of fractures due to localised periarticular osteoporosis. Overall bone quality is assumed to be poorer, however, in patients with rheumatoid arthritis, leading to higher risk of fracture than the bone mineral density measurements seem to show. Data are lacking on the effect of antiresorptive drugs on this condition. Treatment with oestrogen and the bisphosphonate pamidronate has been shown to increase bone mineral density. Data are lacking on fractures. As shown in the case of primary osteoporosis, decreased risk of fracture is to be expected also in patients with secondary osteoporosis.
