Circulating anticoagulant against factor XI and thrombocytopenia with platelet aggregation inhibition in systemic lupus erythematosus.
In a patient with systemic lupus erythematosus, anticoagulant activity directed against factor XI was found together with thrombocytopenia. In the serum globulin fraction, antiplatelet antibodies and an activity-inhibiting platelet aggregation could also be found. A possible correlation between the inhibition of platelet aggregation and the anticoagulant activity directed against factor XI is discussed.
