Comparable conventional x-rays had xeroradiographs were obtained of the hands of 22 patients with rheumatoid arthritis. Each metacarpophalangeal and proximal interphalangeal joint was scored for juxta-articular osteoporosis, erosions, loss of joint space, soft tissue thickening, joint deformity, and osteophytes on a 0-3 scale. For 10 hands the films were reported again after 3 months, and each ...

rheumatoid factors (rf) are autoantibodies with specificity for the fc portion of human igg. production of rf is a characteristic feature of rheumatoid arthritis (ra) and is detectable in high titer in about 90% of these patients. in this study, we measured total igm, iga, igmrf and igarf in serum and synovial fluid of 45 ra patients by elisa and the results were compared with those obtained by...

background and objectives: the cause and pathophysiology of rheumatoid arthritis has not been fully understood and an experimental model of this disease is essential for research on the problem. in this research study, establishment and histopathological changes of chronic arthritis due to intra-articular antigen injection was used as a model of experimental rheumatoid arthritis. materials and ...

Introduction Rheumatoid arthritis (RA) patients are, as a consequence of their disease and its treatment, believed to have an increased risk for osteoporosis. As inhibitors of bone resorption, bisphosphonates are becoming widely used in the management of postmenopausal and glucocorticoid-induced osteoporosis (GIO). Also vitamin D and calcium therapy has been used for the treatment of GIO. Howev...

OBJECTIVE To quantify the magnitude and distribution of osteoporosis in rheumatoid arthritis (RA). METHODS Bone mineral density (BMD) was measured by dual x-ray absorptiometry, in a monozygotic co-twin control study. RESULTS BMD was reduced at most skeletal sites in the twin with RA compared with the co-twin (lumbar spine 4.6%, femoral neck 9.7%, total body 5.7%). Differences in lean soft t...
