BACKGROUND: Antiphospholipid syndrome (APS) may carry a worse prognosis for vascular complications when co-existing with subclinical atherosclerosis; however, the association between the two conditions remains ambiguous. METHODS: We evaluated ultrasonographic markers of subclinical atherosclerosis in carotid and femoral arteries of 86 patients with thrombotic APS [43 primary APS (PAPS), 43 systemic lupus erythematosus-associated APS (SLE/APS)], 86 patients with diabetes mellitus (DM) and 86 healthy controls, individually matched for age and gender, and investigated their associations with traditional and disease-related factors in APS...

OBJECTIVES: To study the effect of the metabolic syndrome (MetS) on organ damage and mortality in patients with SLE. METHODS: Consecutive patients who fulfilled ≥4 ACR criteria for SLE were assessed for the MetS in October 2010. The MetS was defined by the updated joint consensus criteria, using the Asian criteria for central obesity. Longitudinal data on organ damage and mortality were retrieved. The association between MetS and new damage and mortality was studied by logistic regression...

Antiphospholipid syndrome (APS) is an autoimmune disease defined by accelerated atherosclerosis, arterial and venous thrombosis, fetal loss, and the presence of antiphospholipid antibodies (aPL) in the serum and which leads to the occurrence of various vascular events. Nonspecific abdominal pain can be one of the symptoms due to changes on visceral blood vessels. The goal of our work is to show the results we obtained in multidetector computed tomography (MDCT) angiography examination of visceral arteries, comparing patients with primary antiphospholipid syndrome (PAPS) and secondary antiphospholipid syndrome (SAPS) with control group...

INTRODUCTION: Systemic lupus erythematosus (SLE) commonly affects women of childbearing age. Hypertension, antiphospholipid syndrome and lupus nephritis are risk factors for adverse maternal/fetal outcome. The aim of this retrospective cohort study is to compare pregnancy outcomes in patients with and without SLE nephritis, using a multidisciplinary approach and a broad prophylaxis protocol. MATERIALS AND METHODS: Data were collected from 86 pregnancies complicated by SLE...

Primary hemostasis begins with endothelial injury. VWF, produced by endothelial cells, binds to platelets and links them to subendothelial collagen. Platelet-derived ADP and thromboxane activate non-adhered platelets via their GPIIb/IIIa receptors, allowing these platelets to participate in platelet aggregation. Secondary hemostasis is initiated with the binding of factor VII to extravascular tissue factor (TF). Factors II, VII, IX and X are vitamin K-dependent factors. The role of vitamin K is to assist in the addition of gamma carboxylate groups to glutamic acids in the "GLA" domains of these factors...

Antiphospholipid antibody syndrome (APS) is an autoantibodymediated thrombophilic disorder that causes a hypercoagulable state and can lead to venous thromboembolism, stroke, multiple miscarriages, and other pregnancy complications with the presence of antiphospholipid antibodies. This article reviews screening, diagnosis, and management of APS with a focus on the prevention of long-term complications.

OBJECTIVE: Antiphospholipid syndrome (APS) is a systemic autoimmune disorder of young adults associated with devastating pregnancy complications (recurrent miscarriages, preeclampsia and low birth weight) and vascular complications including thrombosis. The key components implicated in pathogenesis of APS are the complement cascade and tissue factor (TF) activity causing inflammation and coagulation. Purinergic signalling involving catabolism of ATP to adenosine by cell-surface enzymes CD39 and CD73 has anti-inflammatory and anti-thrombotic effects...

IgA anti-beta2-glycoprotein I (IgA-aB2GPI) antibodies are currently not included as a laboratory criterion of antiphospholipid syndrome (APS). In the 13th International Congress on Antiphospholipid Antibodies, Galveston, TX, (USA) in 2010, these antibodies were accepted as an APS laboratory criterion in patients who had clinical manifestations of APS but were negative for "consensus" antiphospholipid antibodies (aPL) (IgG and IgM isotypes). Consequently, individuals with thrombotic events who are negative for consensus aPL may be undiagnosed for APS...

Neurologic manifestations are common in patients with antiphospholipid antibodies and include stroke, seizures, dementia, cognitive dysfunction, chorea, migraine, psychosis, and demyelinating disease. Many of these disorders mimic their idiopathic counterparts, yet treatment for antiphospholipid antibody-associated disease can be quite different compared with treatment of CNS disease not associated with these antibodies. For patients with antiphospholipid antibody-associated neurologic disease, anticoagulation or immunosuppressive therapy or both may significantly improve their symptoms...

Objectives The aim of this study was to investigate the association between antiphospholipid antibodies and non-thrombotic and non-gestational manifestations of systemic lupus erythematosus. Methods Systemic lupus erythematosus patients with persistently positive antiphospholipid antibodies or lupus anticoagulant were identified and grouped as systemic lupus erythematosus with antiphospholipid syndrome (SLE-APS), systemic lupus erythematosus with positive antiphospholipid antibodies/lupus anticoagulant without antiphospholipid syndrome (SLE-aPL), and systemic lupus erythematosus with negative aPLs (SLE-No aPL)...

Domain I (DI) of beta-2-glycoprotein I (β2GPI) contains the immunodominant epitope for pathogenic antiphospholipid antibodies (aPL). DI is exposed in the linear form of the molecule but not in the circular form that comprises 90% of serum β2GPI. The majority of circulating β2GPI is biochemically reduced with two free thiols in Domain V. However, increased levels of oxidised β2GPI are found in patients with antiphospholipid syndrome (APS). It is not known whether oxidation of β2GPI favours the linear form of the molecule and thus promotes development of anti-DI antibodies...

PURPOSE: International consensus criteria for antiphospholipid syndrome (APS) require persistently positive antiphospholipid antibodies (aPL) and medium or high titers in association with clinical manifestations. However, the clinical relevance of persistence and titers of aPL in patients with stroke has not been identified. We aimed to investigate the risk of subsequent thrombotic events in patients with ischemic stroke with aPL positivity in terms of aPL status. MATERIALS AND METHODS: We reviewed the medical records of 99 patients with ischemic stroke with at least one or more aPL-positivity (i...

Antiphospholipid syndrome (APS) is an autoimmune disease that is characterized by arterial and/or venous thrombosis and/or recurrent pregnancy losses. Obstetric APS (OAPS) is considered as a distinct entity from vascular APS (VAPS). In the absence of any additional disease, APS is designated as primary (PAPS), while the term secondary APS (SAPS) is used when other diseases are associated. Catastrophic APS (CAPS) is characterized by the rapid development of multiple thrombosis in various vital organs. The presence of antiphospholipid antibodies (aPL Abs) is considered as a laboratory criterion for APS diagnosis...

Essentials Antiphospholipid antibodies (aPL) are heterogeneous and induce different cellular responses. We analyzed signaling events induced by different monoclonal and patient aPL in monocytes. Two major signaling pathways involving either NADPH-oxidase or LRP8 were identified. Our data suggest that these two pathways mediate the majority of aPL effects on monocytes. SUMMARY: Background Antiphospholipid antibodies (aPLs) contribute to the pathogenesis of the antiphospholipid syndrome (APS) by induction of an inflammatory and procoagulant state in different cell types, and several signaling pathways have been described...

Diffuse alveolar hemorrhage (DAH) is a rare but potentially fatal complication in systemic lupus erythematosus (SLE). DAH is typically characterized by hemoptysis, dyspnea, new infiltrates on chest x-rays or CT-scans and a drop in hemoglobin. DAH is seen in less than 2% of patients with SLE and carries a high acute mortality risk of up to 70-90%. The current treatment of DAH is high-dose intravenous corticosteroids, cyclophosphamide and extensive supportive care. Plasmapheresis is also often considered in the treatment...
