BACKGROUND Laboratory detection of intrathecal synthesis of specific antitreponemal antibodies remains a challenge. Traditional syphilis serology is unable to provide a satisfactory result; therefore, several other diagnostic procedures were used to demonstrate central nervous system (CNS) involvement in this disease. The introduction of molecular methods makes today's laboratory testing easier...

Antiphospholipid syndrome (APS) is typically characterized by increased levels of three classes antiphospholipid antibodies, namely lupus anticoagulant, anti-β2-glycoprotein I (anti-β2GPI), and anticardiolipin antibodies. β2-Glycoprotein (β2GPI) a phospholipid-binding protein composed five domains (DI–V) major antigen in APS. β2GPI expressed on the surfaces several cell types, including endothe...

Background and Purpose The aims of this prospective and multicenter study were to determine the frequency of anticardiolipin and antinuclear antibodies in an unselected ischemic and hemorrhagic stroke population and to evaluate the clinical significance of these autoantibodies. Methods Over a 1-year period, we collected plasma from 481 consecutive patients with ischemic or hemorrhagic stroke at...

A 52-year-old man was admitted to hospital with chest pain after physical activity. Emergency coronary angiography showed multiple thromboembolic occlusions in the anterior descending coronary artery and in the right coronary artery. Further testing revealed anticardiolipin and 2-glicoprotein antibodies (the patient had been diagnosed for ulcerative colitis and polymyalgia rheumatica). Heparin...

R a Abstract. Production of factor VIII or factor IX inhibitors is a major complication limiting the efficiency of substitutive therapy in haemophiliacs. Moreover, viral infections, the second serious complication of replacement therapy, may be associated to the occurrence of antiphospholipid antibodies which paradoxically lead to thrombosis. We investigated the prevalence of coagulation inhibi...
