[Immunomorphological characteristics of the synovial membrane in rheumatic diseases].
The synovial membrane is frequently a target in rheumatic diseases. A search for diagnostic criteria and determination of changes in the pathological process necessitate standardized biopsy diagnostic techniques and quantification of morphological changes using digital imaging methods. The paper considers main methods for obtaining synovial membrane samples. It presents major morphological and immunohistochemical variations in synovitis in the presence of rheumatoid arthritis, ankylosing spondylitis, and osteoarthrosis. It shows different immunological and autoinflammatory mechanisms of these diseases. Synovial membrane inflammation in rheumatoid arthritis, ankylosing spondylitis, and osteoarthrosis is characterized by different components of morphogenesis, which is proven by the expression of different cell markers. Rheumatoid synovitis is an autoinflammatory process; synovitis in ankylosing spondylitis is characterized by autoinflammatory processes; biomechanical factors as joint inflammation triggers are leading in osteoarthrosis.
