The role of LRP8 (ApoER2') in the pathophysiology of the antiphospholipid syndrome

Abstract

One of the greatest enigmas in thrombosis research is the observation that one can diagnose a person with a thrombotic risk with a prolongation of the clotting time. Our textbooks have taught us that prolongation of clotting correlates with a tendency to bleed. To confuse our textbook knowledge further, the same patients often have a prolonged bleeding time, a diagnostic test to detect a dysfunction in primary haemostasis. In this paper we critically review the literature that tries to explain the contradiction that exists between in-vitro diagnostic tests and the observed clinical manifestations and discuss our current opinion on how antiphospholipid antibodies can disturb the haemostatic balance.
