2. Antiphospholipid antibodies and cerebral thrombosis 2.1. Lupus anticoagulant In neonates and children, LAC are sometimes found incidentally due to prolongation of activated partial thromboplastin time (20). As LAC can be transient and associated with infections and transplacental passage (21, 22), they are not usually associated with clinically relevant complications (23). Therefore, the differentiation between de novo and acquired LAC has important therapeutic implications and is c...
