The Antiphospholipid Syndrome in the Pediatric Population.

Pediatric antiphospholipid syndrome (APS) is characterized by autoantibodies directed against protein complexes on cellular membranes and leads to a prothrombotic, proinflammatory state. A child with APS may present with venous, arterial, or small vessel thrombosis. Other manifestations of APS include nonthrombotic manifestations, such as hematologic and neurologic symptoms. APS may be a primary condition or related to other autoimmune diseases. If APS-related thrombosis is unrecognized, the child may suffer recurrent thrombotic events after the withdrawal of anticoagulation. Thus, it is important to consider APS as a cause of thrombosis in children. Appropriate testing confirms the diagnosis and directs further care.
