Antiphospholipid antibody syndrome is characterized by venous and/or arterial thrombosis and/or pregnancy morbidity associated with antiphospholipid antibodies (aPL), such as anticardiolipin antibodies, anti beta 2 glycoprotein I antibodies and positive lupus anticoagulant test. This syndrome may potentially affects any organ system including the skin. Livedo reticularis is the most frequently ...

The concept of antiphospholipid syndrome (APS) has been established (1). It is well-known that one of the clinical features in APSis arterial or venous thrombosis, and that the specificity of so-called antiphospholipid antibodies have diversity against their epitopes, as so-called antiphospholipid antibodies react to phospholipids as well as plasma proteins such as p2-glycoprotein I and prothro...

Abnormalities in the thyroid function and thyroid autoantibodies have been frequently described in patients with autoimmune diseases but seldom in antiphospholipid syndrome patients. In order to determine the prevalence of thyroid function and autoimmune abnormalities, we compared serum thyrotropin (TSH, serum free thyroxine (T4) levels, thyroid antithyroglobulin (TgAb) and antithyroperoxidase ...

CONTEXT Antiphospholipid syndrome is often associated with systemic lupus erythematosus. Both syndromes have different clinical manifestations based on organ involvement. Antiphospholipid syndrome commonly causes spontaneous abortions, cerebral vascular occlusion, and deep venous thrombosis. Catastrophic antiphospholipid syndrome occurs when three or more organ systems are affected by thrombose...

Most ophthalmologic disorders secondary to hypercoagulabe state are due to the confluence of congenital and adquired factors. A systematic workup is mandatory. Most of congenital coagulation disorders cause venous trombosis and are inherited autosomal dominantly. In order of frequency these are factor V Leiden mutation (activated protein C resistance), G20210A mutation of the prothrombin gen an...

The association of thrombosis and gestational morbidity with antiphospholipid antibodies is termed antiphospholipid syndrome (APS). Annexin 2 (A2) is a profibrinolytic endothelial cell surface receptor that binds plasminogen, its tissue activator (tPA), and beta(2)-glycoprotein I (beta2GPI), the main antigen for antiphospholipid antibodies. Here, we evaluate A2 as a target antigen in APS. Serum...

INTRODUCTION Myasthenia gravis is an autoimmune disease characterized by fluctuating muscle weakness. It is often associated with other autoimmune disorders, such as thyroid disease, rheumatoid arthritis, systemic lupus erythematosus, and antiphospholipid syndrome. Many aspects of autoimmune diseases are not completely understood, particularly when they occur in association, which suggests a co...

Chorea may occur as a neurological manifestation of systemic lupus erythematosus and is often associated with detection of antiphospholipid antibodies. No evidence of chorea as a sign of lupus activity has been established. We describe a patient with systemic lupus erythematosus associated with antiphospholipid antibodies who developed chorea, which has been considered a sign of lupus activity.

Heparin-induced thrombocytopenia (HIT) is a prothrombotic adverse drug reaction in which heparin forms complexes with platelet factor 4 forming neoantigens that are recognized by autoantibodies. Antiphospholipid syndrome (APS) is similar to HIT in that it is mediated by autoantibodies that are also prothrombotic. We present a case of rare coexistence of antiphospholipid antibody syndrome and he...
