Abstract

Findings of prolonged activated partial thromboplastin time (APTT) and lupus anticoagulant are rare in asymptomatic children and are often preceded by certain types of surgery. Clinical behaviour is usually favorable. We assessed the biological and clinical features of antiphospholipid antibodies found in 13 children diagnosed between January 1996 and September 2000 (mean age at diagnosis: 5 years). The patients were prospectively followed-up for a median of 16 months (range: 15-60). The diagnosis of lupus anticoagulant was based on the guidelines of the International Society of Thrombosis and Hematosis and included coagulation-based assays as well as enzyme-linked immunosorbent assay for anticardiolipin and anti-beta 2 glycoprotein I. In all patients lupus anticoagulant was detected after investigation of prolonged APTT prior to surgery (adenoidectomy in eight patients, orchidopexy in one and eye surgery in one). The antibody was associated with infectious mononucleosis in one patient and was detected during routine laboratory investigations in two. All antibodies were primary and 53.6% of events were transient. In all patients lupus anticoagulant IgG and anti-beta 2 glycoprotein I were negative. Slightly reduced factor XII:C ...Continue Reading

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
