BACKGROUND: Intravenous immunoglobulin (IVIG) has recognized efficacy in autoimmune peripheral nerve disorders, but there has been limited study of the use of IVIG in autoimmune dysautonomias. STUDY QUESTION: To determine the efficacy and safety of IVIG in patients with disabling, refractory autoimmune dysautonomias, including patients with postural tachycardia syndrome and gastrointestinal dysmotility. STUDY DESIGN: Patients with one or more autonomic disorder(s) and persistent serological evidence for autoimmunity who were unable to work or attend school despite usual treatments for dysautonomia were treated with IVIG for at least 3 months at a dose of at least 1 gm/kg monthly...

Neurological involvement in antiphospholipid antibody syndrome (APS) is common, and its occurrence increases morbidity and mortality. Patients may present variable neurological involvement, such as cerebrovascular disease, cognitive dysfunction, headache, seizures, movement disorders, multiple sclerosis-like syndrome, transverse myelitis and ocular symptoms. Most neurological manifestations are associated with thrombosis of the microcirculation or of large vessels; nonetheless, there is compelling evidence suggesting that, in some cases, symptoms are secondary to an immune-mediated pathogenesis, with direct binding of aPL on neurons and glia...

OBJECTIVE: Until now, concomitant neurological manifestations and positive antiphospholipid antibodies (APA(s)) have been investigated in different manners. The most important conflicts in this field are whether those manifestations are directly related to APA(s) or not and treatment strategies. METHOD: In this study, adopting a different manner, we selected patients with a recently defined neurological problem (according to study protocol) and positive APA without any other risk factor, to compare types, amounts, and titer of APAs...

INTRODUCTION: Rotational thromboelastometry (ROTEM) is increasingly used as a tool for monitoring coagulation status. However, ROTEM is susceptible to misinterpretation due to particular coagulation abnormalities. Here, we report the effects of lupus anticoagulant (LA) on ROTEM. METHODS: A prospective observational analysis was performed on 16 children with prior studies indicating the presence of LA or antiphospholipid antibodies. ROTEM analysis was performed, and samples were further analyzed by adding phospholipids (PL) to repeat ROTEM analysis if clotting time (CT) abnormalities were discovered with comparison to ROTEM using an equal volume of isotonic saline...

The antiphospholipid antibody syndrome (APS) is defined by a state of hypercoagulability secondary to an autoimmune disorder. There are evidences that approximately 2.8-5.5% of cases of acute myocardial infarction (AMI) in young individuals are secondary to APS. In this case report, three coronary artery thromboses occurring within a short period are described. Initially, there was an ST-segment elevation (STEMI) in the presence of coronary artery disease (CAD), with the vessel being treated with stent implantation...

The process of finding new therapeutic indications for currently used drugs, defined as 'repurposing', is receiving growing attention. Chloroquine and hydroxychloroquine, with an original indication to prevent or cure malaria, have been successfully used to treat several infectious (HIV, Q fever, Whipple's disease, fungal infections), rheumatological (systemic lupus erythematosus, antiphospholipid antibody syndrome, rheumatoid arthritis, Sjögren's syndrome), and other immunological diseases. Indeed, they have anti-inflammatory, immunomodulating, anti-infective, antithrombotic, and metabolic effects...

The complement and coagulation cascades interact at multiple levels in thrombosis and inflammatory diseases. In venous thrombosis, complement factor 3 (C3) is crucial for platelet and tissue factor (TF) procoagulant activation dependent on protein disulfide isomerase (PDI). Furthermore, C5 selectively contributes to the exposure of leukocyte procoagulant phosphatidylserine (PS), which is a prerequisite for rapid activation of monocyte TF and fibrin formation in thrombosis. Here, we show that monoclonal cofactor-independent antiphospholipid antibodies (aPLs) rapidly activate TF on myelomonocytic cells...

Antiphospholipid syndrome (APLS) is caused by antiphospholipid autoantibodies, and manifests with vascular and/or obstetric complications. The factors associated with initial disease presentation and course are unknown. We assessed the antibody profile associated with disease presentation and with the development of vascular and obstetric complications in women with initially vascular or initially obstetric APLS. A review of records of APLS women at childbearing age followed at one center during 2006-2015. Of 126 women, median age at diagnosis 29 [23-37] years, 62 were initially diagnosed with purely obstetric APLS and 64 with purely vascular APLS...

Objectives: APS is associated with arterial and venous thrombosis. The unfavourable fibrin clot phenotype, including formation of dense and poorly lysable clots, has been reported in thrombotic APS. We investigated whether abnormal plasma clot properties are predictive of recurrent thromboembolism in APS. Methods: We followed 126 consecutive patients with thrombotic APS and 105 control subjects, without APS, matched for thrombotic events. Plasma fibrin clot permeability (Ks), turbidity measurements and clot lysis time were evaluated ⩾5 months after a thrombotic event...

Antiphospholipid antibody (aPL)‑mediated antiphospholipid syndrome (APS) is an autoimmune disease. Upon binding to aPL, the primary antigen of aPL, β2‑glycoprotein I (β2‑GP I), induces abnormal immune function, which further activates downstream signaling pathways in the cell and eventually leads to APS. The present study aimed to determine whether β2‑GP I antigen and anti‑β2‑glycoprotein I antibody (aβ2‑GP I), which belong to the aPL class of antibodies, may affect human chorionic epithelium cell (JEG‑3) proliferation, migration and invasion...

BACKGROUND: Increasing evidence has highlighted the role of non-criteria antiphospholipid antibodies (aPLs) as important supplements to the current criteria aPLs for the diagnosis of antiphospholipid syndrome (APS). In this retrospective study, we evaluated the clinical relevance of antibodies to phosphatidylserine/prothrombin (aPS/PT) in Chinese patients with APS. METHODS: A total of 441 subjects were tested, including 101 patients with primary APS (PAPS), 140 patients with secondary APS (SAPS), 161 disease controls (DCs) and 39 healthy controls (HCs)...

Recognizing the antiphospholipid syndrome (APS) in patients with lupus (SLE) can be difficult and therefore underestimated. Detection of antiphospholipid antibodies (aPL) in each patient with SLE should be done as a rule. Introduction of the new classification criteria of this syndrome will certainly improve the recognition of APS in the future. The Sapporo APS classification criteria (1998) were replaced by the Sydney criteria in 2006. Based on the most recent criteria, classification with APS requires one clinical and one laboratory manifestation...

We present a case of acute post-streptococcal glomerulonephritis (APSGN) with autoimmune hemolytic anemia (AIHA). Along with the classic findings of APSGN, the patient had a positive direct antiglobulin test and an anticardiolipin antibody without any typical clinical manifestations of antiphospholipid syndrome (APS). This case raises questions of the relationship between Streptococcus and the development of autoimmune hemolytic anemia in children. Our case highlights the possibility that the streptococcal infections in this patient might be responsible for her anemia, either in setting of underlying antiphospholipid antibodies, or in having triggered the development of pathogenic antibodies, which subsequently leads to the clinical evolution of hemolysis...
