BACKGROUND A high incidence of both arterial and venous thromboembolic events has been reported in patients with systemic lupus erythematosus (SLE), but the risks and benefits of primary prophylactic antithrombotic therapy have not been assessed. We measured the clinical benefit of 3 antithrombotic regimens in patients with SLE without antiphospholipid antibodies, with anticardiolipin antibodie...

background: in lupus nephritis (ln), deposition of pathogenic autoantibodies in the glomeruli is mediated via cross-reactivity with alpha-actinin. association of serum alpha-actinin antibody (aαa) with ln has been shown in a few studies but the results are controversial. methods: eighty patients into entered the study. the diagnosis of sle was confirmed according to the american college of rheu...

showed portal vein thrombosis with progression to superior and inferior mesenteric vein and splenic vein (Figure 1). Antithrombin III, protein C and S were normal; lupus anticoagulant 1.19 (<1.2); anticardiolipin antibody was positive (IgG 30.5/IgM 50: <10). Our patient meets the criteria for SLE and for APS [1,4]. APS is characterized by lupus anticoagulant, anticardiolipin antibodies, vascula...

the neuropsychiatric manifestations of systemic lupus erythematosus are frequent. one of the most serious presentations is convulsion. this study was carried out to evaluate the relation between convulsion and anti-dna antibody levels. an analytic, retrospective case-controlled study was carried out, with reference to 1001 recorded cases of systemic sle lupus erythematosus in lupus unit, rheuma...

We investigated the clinical and pathologic characteristics of stroke in 234 patients with systemic lupus erythematosus. Thirteen patients (5.6%) developed cerebrovascular disease. Cerebral infarction was noted in eight, cerebral hemorrhage in two, and subarachnoid hemorrhage in three. In seven (54%) of these 13 patients, stroke occurred less than or equal to 5 years after systemic lupus erythe...

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...

Hybridomas the produce anti-DNA autoantibodies were prepared from spleen cells of unimmunized MRL/1 mice, a strain that spontaneously develops severe systemic lupus erythematous (SLE). Reactivities of these monoclonal antibodies with a wide range of polynucleotides prompted tests of their reactions with phospholipids which, like polynucleotides, contain diester-linked phosphate groups in their ...

We have determined lupus anticoagulants, anti-beta2 glycoprotein I (beta2GPI) and antiprothrombin antibodies in the Leiden Thrombophilia Study, a population-based case-control study designed to determine risk factors for deep venous thrombosis (DVT). Lupus anticoagulant (LAC) was measured in 473 patients and 472 control subjects. Four control subjects (0.9%) and 14 patients (3.1%) had a positiv...
