Antiphospholipid antibodies, including anticardiolipin antibodies, are frequently detected in sera from patients with systemic lupus erythematosus (1). Numerous reports have associated these autoantibodies with various venous and arterial thrombotic disorders, including cerebral infarction (2), deep venous thrombosis (3), thrombocytopenia (1), pulmonary embolism (4), and recurrent fetal loss wi...

Introduction: Pemphigus vulgaris is an autoimmune blistering disease of the skin and mucous membrane. Antiphospholipid antibodies are a group of autoantibodies found in patients with autoimmune diseases. Due to the risk for thrombotic events in autoimmune diseases, we decided to evaluate the correlation between pemphigus vulgaris and predictive elements of atherothrombosis including antiphospho...

Anticardiolipin antibodies are produced both in patients with the antiphospholipid syndrome (APS) and in patients with syphilis, but lupus anticoagulant activity has been reported only for the former group. To understand these differences, affinity-purified immunoglobulin G anticardiolipin antibodies from APS (n = 11) and syphilis (n = 5) patients were compared. Only the antibodies from the APS...

Background: Graves’ disease is an autoimmune disease, characterized by the presence of antibodies directed to TSH receptor or nearby regions as well as antibodies to double strands DNA (dsDNA) anticardiolipin and nuclear antibodies. This study evaluated anticardiolipin and rheumatoid factor, such as IgA and IgM antibodies in patients with Graves’ disease. Patients and methods: Anticardiolipin a...

The prevalence of antiphospholipid and antinuclear antibodies in 102 patients with at least three unexplained miscarriages before a gestational age of 12 weeks, or at least one intrauterine fetal death after 12 weeks, was investigated and compared with the prevalence in 102 normal pregnant controls. Six patients had a history of thrombosis and six had 'lupus-like' disease. Twenty one patients h...
