Synovial Iron Deposition in Rheumatoid Arthritis

Synovial hyaluronate in rheumatoid arthritis

Acute inflammation of joints can lead to the development of chronic arthritis. The nature of agents that sustain the chronic inflammation remains an enigma, although infectious agents such as Rubella virus, Epstein-Barr virus or Chlamydia have been invoked. In most cases in which an inducing agent was sought, none was found.' However, several antigens have been identified that elicit acute arth...

Synovial activation in rheumatoid arthritis.

Rheumatoid arthritis (RA) is a chronic inflammatory disease with progressive articular damage. Activated cells of the synovium produce pro-inflammatory and matrix-degrading effector molecules, which maintain the inflammation and lead to the destruction of the involved joints. In addition to macrophages and T- and B-cells, fibroblast-like synoviocytes must be considered key cells in driving the ...

Iron in rheumatoid arthritis.

syiNopsis Serum ferritin concentration has been compared with semi-quantitative histochemical estimates of bone marrow iron deposits in 60 anaemic patients with rheumatoid arthritis. There was considerable variation in the visual assessment of iron stores made by different observers. Serum ferritin appears to be a particularly sensitive index of iron status when stores are low. The best means o...

Rheumatoid arthritis: a synovial disease?

Hypothesis Although rheumatoid arthritis (RA) is believed to be primarily an inflammatory disease of synovium, there is a good possibility that the initiation of the rheumatoid process is triggered by the autoimmune reaction involving type II collagen in the articular cartilage as a consequence of an unknown aetiological agent. Synovitis and other extra-articular features may be induced seconda...
