[Change in phospholipid composition of synovial fluid in children with various types of arthritis]. / Izmenenie fosfolipidnogo sostava sinovial'noi zhidkosti u detei s razlichnymi artritami.

Phospholipid composition of synovial fluid was studied in patients with reactive, rheumatoid and juvenile chronic forms of arthritis as compared with that of normal synovial fluid. The most pronounced alterations of the synovial fluid phospholipid composition (additional phospholipid fractions, increase in content of lyso-derivatives) were found in the patients with rheumatoid and juvenile chronic arthritis, which appear to occur due to activation of endogenous phospholipases A2, C and lysophospholipase A1.
