چکیده

BACKGROUND Data on pediatric antiphospholipid syndrome (APS) are very sparse. OBJECTIVES To describe the main clinical characteristics, laboratory data and complications of pediatric APS patients, and to analyze the differences between primary APS and APS associated with systemic lupus erythematosus (SLE). METHODS We retrospectively reviewed clinical and laboratory data of 32 children at the Federico Gomez children's hospital in Mexico. Nineteen patients had SLE, 12 (37.5%) had primary APS and 1 (3%) had immune thrombocytopenic purpura. We collected information on sociodemographic variables, vaccinations, age at onset, and family history of rheumatic disease, hematological disorders, skin disorders and non-thrombotic neurological disorders. Immunological features included immunoglobulin (Ig) G and IgM anticardiolipin antibodies, IgG and IgM anti-beta2 glycoprotein I antibodies, lupus anticoagulant, and anti-dsDNA and antinuclear antibodies. RESULTS The patients included 24 females and 8 males. The most common thrombotic events were small vessel thrombosis (44%), venous thrombosis (28%) mainly deep venous thrombosis (DVT) in lower extremities, and arterial thrombosis (25%). The most common clinical non-thrombotic manifestations were hematological (53%) and neurological disorders (22%). There were no significant differences between groups with regard to the site of thrombosis, nonthrombotic clinical manifestations or laboratory features. CONCLUSIONS There were some important differences between the clinical manifestations of APS in children compared with adults, but we found no significant differences between patients with primary and APS associated with SLE. Larger studies in Latin American APS children are necessary to determine whether there are differences between ethnic groups.

Revisiting Beta 2 Glycoprotein I, the Major Autoantigen in the Antiphospholipid Syndrome

Beta 2 glycoprotein I (β2GPI) is a single chain 50 kDa highly glycosylated glycoprotein at an approximate concentration of 4 μM in cells. The abundance of this protein in plasma and its high state of preservation indicate the important role of this protein in mammalian. In addition, β2GPI has a particular structure in the fifth domain, and is categorized as the major antigen recognized by autoa...

PReS-FINAL-2269: Incidence of antiphospholipid antibody syndrome in a cohort of children suffering from either arterial or venous thrombosis

Introduction Arterial or venous thrombosis rarely occurs in children, in almost 70% of these patients an acquired or congenital cause can be identified. Hereditary thrombophilia can be identified in 10-30% of children with other evident causes of thrombosis, and in 60% of children with apparent idiopathic thrombosis. Therefore it is suggested that thrombophilia screening should be done in both ...
