[Inhibition of cardiolipin binding antibodies from synovial fluids of patients with arthritis by endotoxin].

In the presented study was prooven that aCl antibodies cross-reacting with LPS (endotoxin) from arthritic synovial fluids are part of the aPL antibodies pool and correlated with presence in joints bacterial cell wall components like LPS-showing endotoxin presence in synovial fluids and they may be usefull in differential diagnosis of the different kind of arthritis and also in explanation of their aetiology at all--especially in cases of early, undifferentiated arthritis.
