Blood samples from 65 patients with primary Sjögren's syndrome were evaluated for the presence of antiphospholipid antibodies. Increased levels of antiphospholipid antibodies were found in 13 of 65 (20%) of patients. These antiphospholipid antibodies were predominantly of the IgA isotype, in contrast with the IgG isotype antiphospholipid antibodies found in patients with systemic lupus erythema...

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...

The antiphospholipid syndrome is the association between the presence of antiphospholipid antibodies, thrombosis and/or pregnancy morbidity and mortality. This report presents two cases of antiphospholipid antibodies and sensorineural hearing loss and discusses the probable causative link. We recommend that patients presenting with sudden sensorineural hearing loss are investigated for evidence...

A 40-year-old male patient with primary anetoderma is presented in whom antiphospholipid antibodies were detected while not fulfilling diagnostic criteria for antiphospholipid syndrome. The possible pathogenic role of antiphospholipid antibodies in the disease development is postulated.

OBJECTIVE A human lymphoproliferative syndrome characterized by a defect of the Fas-mediated apoptosis pathway in the absence of a fas gene mutation (Autoimmune Lymphoproliferative Disease) has recently been described and characterized by autoimmune phenomena. The aim of this study was to investigate the presence of antinuclear and antiphospholipid antibodies and to define their specificity in ...

conclusions antipospholipid antibodies based on number of abortions and gestational age of abortions were increased. mean antipospholipid and anticardiolipin antibodies in all patients remained in high level just in first 5 years post abortion and then began to fall. results mean age of participants was 24-39 years old. the average rate of antiphospolipid antibodies in patients with normal anti...

Antiphospholipid antibodies have an established association with pregnancy complications such as recurrent miscarriage, growth retardation, placental abruption and stillbirth but their mechanism of action is unclear. We have investigated whether antiphospholipid antibodies occur more frequently in women having in-vitro fertilization (IVF) and whether their presence is associated with the likeli...

manifestation of chorea in patients with systemic lupus erythematosus (sle) and antiphospholipid antibody syndrome (apa synd.) is not common. moreover, primary presentation of the disease with chorea is rare and only few such cases are reported in literature in recent years. we report here the case of a 28 year old woman who was first seen at the age of 10 with clinical manifestations of chorea...

Haemostasis is a delicate balance between procoagulant and anticoagulant processes. In the human body usually anticoagulant mechanisms prevail over procoagulant mechanisms, thereby preventing a prothrombotic state. The antiphospholipid syndrome is an example in which this balance is shifted to a more prothrombotic state due to the presence of antiphospholipid antibodies. One of the most extensi...
