objective: the study aimed to determine the relationship between presence of antiphospholipid antibodies (apls) and clinical pregnancy rate in patients undergoing ivf/icsi procedures. materials and methods: this descriptive-analytic study performed on two hundred consecutive women referred for ivf/icsi in vali-e-asr reproductive health research center. serum levels of apls , anticardiolipin [ac...

etiologic factors for recurrent miscarriage (rm) include autoimmune diseases, the most frequently antiphospholipid syndrome and thyroiditis. some women who suffer from rm might also have an altered immune system. we aimed to evaluate possible associations between anti-thyroid and anti-phospholipid antibodies in women with rm. in a retrospective case series 1 on 156 women with rm, major outcome ...

Following a meeting at Sapporo, Japan, an international consensus statement on preliminary classification criteria for definite anti-phospholipid syndrome was published.1 This set of criteria is divided into the clinical part which includes vascular thrombosis and pregnancy morbidity and the laboratory part which includes anti-cardiolipin (aCL) antibody and lupus anti-coagulant tests. Diagnosis...

Several questions regarding the production and functioning of autoantibodies (AAb) during malaria infection remain open. Here we provide an overview of studies conducted in our laboratory that shed some light on the questions of whether antiphospholipid antibodies (aPL) and other AAb associated with autoimmune diseases (AID) can recognize Plasmodia antigens and exert anti-parasite activity; and...

The presence of antiphospholipid antibodies is linked to an increased rate of repeated spontaneous abortions and fetal deaths, that in fact belong to the clinical spectrum of the antiphospholipid syndrome. The pathogenic role of antiphospholipid antibodies was clearly shown in experimental animals that, when infused during pregnancy, develop placental insufficiency and miscarriages. In addition...

The paper gives some preliminary comments on the submissions to Discovery Challenge on Thrombosis data.

Antibodies against β2-glycoprotein I are a subset of very heterogeneous family of antiphospholipid antibodies. It is well recognised that anti-β2-glycoprotein I antibodies are the main pathogenic players in the autoimmune disease known as antiphospholipid syndrome. Many mechanisms have been proposed through which these autoantibodies could cause microplacental, arterial or venous thrombosis. On...

BACKGROUND Sulfatides are sulfated glycosphingolipids expressed on the surface of erythrocytes, leukocytes, and platelets. Sulfatides interact with several cell adhesion molecules involved in hemostasis. Beta2-glycoprotein I is an anionic phospholipid-binding plasma protein, and the phospholipid-bound form is the target for most anti-phospholipid antibodies that are associated with recurrent th...

We have developed a new solid phase enzyme immunoassay (EIA) for detec tion of anti-phospholipid antibodies in sera and platelet eluates from patients with idiopathic thrombocytopenic purpura (ITP). Antibodies against cardiolipin (CAR), phosphatidylinositol (PI) and phosphatidylserine (PS), not against phos phatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidic acid (PA) and sphyngom...
