OBJECTIVE: The association of antiphospholipid antibody syndrome (APS) and hypercoagulability is well known. Arterial compromise leading to ischemia of organs and/or limbs in patients with APS is uncommon, frequently unrecognized, and rarely described. We evaluated our institutional experience. METHODS: Retrospective review was conducted. From August 2007 to September 2016, 807 patients with diagnosis of APS were managed in our Institution. Patients with primary and secondary APS who required interventions were examined...

PURPOSE OF REVIEW: Antiphospholipid syndrome (APS) is defined as the association of thrombotic events and/or obstetric morbidity in patients persistently positive for antiphospholipid antibodies (aPL). In this review, we will highlight the most important clinical presentations of APS with a focus on the obstetric morbidity, the current management strategies and the outlook for the future. RECENT FINDINGS: The use of aspirin and heparin has improved the pregnancy outcome in obstetric APS and approximately 70% of pregnant women with APS have a successful pregnancy outcome...

The current mainstay of treatment in patients with thrombotic antiphospholipid syndrome (APS) is long-term anticoagulation, mainly with Vitamin K antagonist agents. Some recently available studies have created new ground for discussion about the possible discontinuation of anticoagulation therapy in patients with a history of thrombotic APS in whom antiphospholipid antibodies (aPL) are not detected any longer (i.e. aPL seroconversion). We report the main points discussed at the last CORA Meeting regarding the issue whether or not anticoagulation can be stopped after aPL seroconversion...

PURPOSE OF REVIEW: Antiphospholipid antibody syndrome (APS) is characterized primarily by thrombosis and pregnancy morbidity. Chronic vascular lesions can also occur. While the underlying mechanisms of these vascular lesions are not entirely known, there have been multiple theories describing the potential process of vasculopathy in APS and the various clinical manifestations associated with it. RECENT FINDINGS: Recently, it has been demonstrated that endothelial proliferation in kidneys can be explained by the activation of the mammalian target of rapamycin complex (mTORC) pathway by antiphospholipid antibodies (aPL)...

All biological risk factors that have been previously identified to increase the risk of thrombosis in adults, have also been studied in neonates with arterial Ischemic Stroke (NAIS), but most studies were retrospective and included relatively low numbers of affected children. We therefore could not suggest recommendations with a strong level of evidence and only expert proposals potentially useful for clinical practice will be presented in this text. Despite these limitations, the extensive analysis of published data supported that factor V Leiden (FVL) and increased levels of Lp(a) could be significant risk factors for NAIS...

OBJECTIVE: Most clinicians use the 2006 Sydney classification criteria to evaluate patients suspected of having antiphospholipid syndrome (APS). Although sensitive and specific for APS, many patients fulfilling clinical criteria for the syndrome are persistently negative for the specific serological tests ("laboratory criteria"). These "seronegative APS" (SN-APS) patients can go undiagnosed and untreated until they experience serious clinical events. This study's objective was to describe antibody profiles of SN-APS patients using non-criteria markers, assess the clinical utility of these markers separately and in combination, and suggest incorporation into guidelines for patients suspected of APS...

The aim of this study was to understand the clinical features of antiphospholipid syndrome (APS)-complicated pregnancies and evaluate risk factors for the adverse pregnancy outcomes. This multicenter study evaluated live-birth rates according to therapy modality for APS and risk factors of pregnancy loss in 81 pregnancies. Risk factors for pregnancy complications, including premature delivery before 34 gestational weeks, hypertensive disorders of pregnancy, thrombocytopenia, and light-for-date neonate, were evaluated in 51 women who received low dose aspirin (LDA) plus unfractionated heparin (UFH) and delivered after 24 GW...

BACKGROUND: Catastrophic antiphospholipid syndrome (CAPS) is an uncommon, often fatal, variant of the antiphospholipid syndrome (APS) that results in a widespread coagulopathy and high titres of antiphospholipid antibodies (aPL) and affects predominantly small vessels supplying organs with the development of multiorgan failure. It remains unclear why some patients develop the typical clinical picture of APS (thrombosis of large vessels), whereas others show the development of progressive microthrombosis, which the authors called "thrombotic storm" and multiple organ failure, that is, CAPS...

To investigate the effects of antiphospholipid antibodies on establishment of pregnancy and changes in hormones such as estradiol-17ß (E2) and progesterone (P) levels in circulation. Hence, mice were immunized with human β2-Glycoprotein I (β2GPI) and the effect of these antibodies on fetuses weight, placental obsrvation, Serum levels of P and E2 in pregnant mice, hematological were observed. Immunization of mice with human β2-GPI resulted in elevated levels of antiphospholipid antibodies. The experimentally induced antiphospholipid syndrome mouse showed higher rate of fetal resorption, low number of viable fetuses, and "placental abnormalities"...

The discovery in the 1990s that the protein beta-2-glycoprotein I (β2GPI) was an antigen of central importance in the antiphospholipid syndrome (APS) was soon followed by the development of ELISA assays capable of identifying anti-β2GPI antibodies recognizing this antigen. The determination of these antibodies has continued to play a major role in the management of APS patients because of their extremely high specificity for diagnosing the disease, despite their relatively poor sensitivity compared to anticardiolipin antibodies...

The anticardiolipin (aCL) test was first developed in the 1980s and proved to be a valuable addition to the lupus anticoagulant assay for identifying patients with a disorder that came to be later known as the antiphospholipid syndrome (APS). Although the test has relatively poor specificity for APS diagnosis, particularly at low positive levels, it has continued to play a major role in the identification and management of these patients because of its high sensitivity and ability to be measured in both serum and plasma, and despite concomitant presence of anticoagulants normally given to APS patients...

Venous thromboembolism, usually entailing deep vein thrombosis, pulmonary embolism, or both, is a complex and multifactorial disorder, in which a number of putative conditions interplay and finally contribute to propel the individual risk over a certain degree, so ultimately culminating in the development of venous occlusive disorders. Thrombophilia is commonly defined as a propensity to develop venous thromboembolism on the basis of an underlying hypercoagulable state attributable to inherited or acquired disorders of blood coagulation or fibrinolysis...

OBJECTIVES: The presence of anti-Ro/SSA and anti-La/SSB antibodies has been linked with autoimmunity in general and with several autoimmune diseases (AID) in particular. In the current study we evaluated these antibodies in a wide spectrum of AID as well as the links between them and anti-infectious antibodies. METHODS: We examined 2082 sera from patients with 16 different AID compared to 524 sera from geographically-matched healthy controls, for the presence and titres of anti-Ro/SSA and anti-La/SSB...

First described in the early 1980s, antiphospholipid syndrome (APS) is a unique form of acquired autoimmune thrombophilia in which patients present with clinical features of recurrent thrombosis and pregnancy morbidity and persistently test positive for the presence of antiphospholipid antibodies (aPL). At least one clinical (vascular thrombosis or pregnancy morbidity) and one lab-based (positive test result for lupus anticoagulant, anticardiolipin antibodies and/or anti-β2-glycoprotein 1 antibodies) criterion have to be met for a patient to be classified as having APS...
