[Hemostasis in patients with rheumatoid arthritis].

Aim: To study hemostasis with reference to rheumatoid arthritis (RA) activity, extraarticular manifestations and vascular damage.

Material And Methods: We studied hemostasis in 104 RA patients. The following parameters were tested: partial thromboplastin time activation (PTTA), fibrinolytic activity (FA), prothrombin index, lupus anticoagulant (LA), mean platelet volume (PV), antibodies against cardiolipin (aCL) and antibodies against beta2-glycoprotein 1 (alphabeta2-GP1).
