Research output: Contribution to journalArticlepeer-review


Antiphospholipid antibody syndrome (APS) is characterized by autoantibodics against negatively charged phospholipids in the serum, and clinically by multiple thromboses, thrombocytopenia, and recurrent fetal loss. The mechanism(s) by which the antibodies cause the clinical picture are not dear. We review the possible mechanisms of action of antiphospholipid (aPL) antibodies. Apparently, aPL antibodies act by interfering with coagulation, involving both endothelial cclls, platelets, and humoral components, and affect pregnancy outcome by interfering with embryo implantation and fetal developement.
