Persistent serum positivity for antiphospholipid antibodies (aPL) is required to diagnose antiphospholipid syndrome (APS), an autoimmune disease characterized by recurrent vascular thrombosis and/or pregnancy morbidity. The current therapeutic management of patients with thrombotic APS aims at preventing recurrences and long-term complications by attenuating the procoagulant state. There is overall consensus to reserve moderate-intensity anticoagulation to aPL-positive patients with a previous venous thrombosis; the therapeutic options for those with a history of arterial event comprise antiplatelet agents and high-intensity anticoagulation...

OBJECTIVE: Systemic lupus erythematosus (SLE) is associated with the premature development of cardiovascular disease. The platelet-endothelium interaction is important in the pathogenesis of cardiovascular disease. In this study, we investigated the platelet phenotype from patients with SLE and matched controls, and their effect on endothelial cells. APPROACH AND RESULTS: Platelet aggregability was measured in 54 SLE subjects off antiplatelet therapy (mean age 40...

Patients presenting with bone marrow fibrosis not accompanied by well-established autoimmune diseases, such as systemic lupus erythematosus, or malignant diseases, are considered to have primary autoimmune myelofibrosis (AIMF). Primary AIMF has been reported to follow a benign course and responds well to treatment with immunosuppressive agents. Immune thrombocytopenia (ITP) is also an autoimmune disorder characterized by antiplatelet-antibody-mediated thrombocytopenia in the absence of other causes of thrombocytopenia...

Antiplatelet agents are proven efficacious treatments for cardiovascular and cerebrovascular diseases. However, the existing drugs are compromised by unwanted and sometimes life-threatening bleeding that limits drug usage or dosage. There is a substantial unmet medical need for an antiplatelet drug with strong efficacy and low bleeding risk. Thrombin is a potent platelet agonist that directly induces platelet activation via the G protein (heterotrimeric guanine nucleotide-binding protein)-coupled protease-activated receptors PAR1 and PAR4...

Immunization against human platelet alloantigens (HPAs) is associated with a number of clinical complications. The detection and identification of clinically relevant platelet antibodies are important for the diagnosis and management of patients affected with immune-mediated thrombocytopenias. Human platelet alloantigen frequencies and the characteristics of antiplatelet antibodies vary widely between ethnic groups. Since 2008, the importance of platelet immunology in the field of transfusion medicine has gained greater recognition by clinical laboratories in China...

B cells are involved in immune thrombocytopenia (ITP) pathophysiology by producing antiplatelet auto-antibodies. However more than a half of ITP patients do not respond to B cell depletion induced by rituximab (RTX). The persistence of splenic T follicular helper cells (TFH) that we demonstrated to be expanded during ITP and to support B cell differentiation and antiplatelet antibody-production may participate to RTX inefficiency. Whereas it is well established that the survival of TFH depends on B cells in animal models, nothing is known in humans yet...

Idiosyncratic hepatotoxicity is one of the most common reasons for an approved drug being restricted. This article focuses on hepatotoxicity of selected and recently introduced agents, such as, tyrosine kinase inhibitors, monoclonal antibodies, novel oral anticoagulants, newer antiplatelets, antibiotics, anti-diabetics, anti-epileptics, anti-depressants, anti-psychotics and anti-retrovirals. Overall, the incidence of clinically relevant hepatotoxicity from newer agents seems to be lower than that of the older agents...

INTRODUCTION: Thrombopoietin-receptor agonists (TPO-RA) are marketed for immune thrombocytopenia (ITP). They have been associated to thrombosis occurrence in randomized controlled trials. However, the characteristics of these thromboses in the real-life practice as well as their management are poorly known. The objectives of this study were to determine the risk factors, circumstances and management of thrombosis occurring during exposure to TPO-RA in ITP. METHODS: We carried out a multicentre retrospective study in France...

BACKGROUND: Recently emerging evidence indicates that endometriotic lesions are wounds undergoing repeated tissue injury and repair (ReTIAR), and platelets induce epithelial-mesenchymal transition (EMT), fibroblast-to-myofibroblast transdifferentiation (FMT), leading ultimately to fibrosis. Due to the commonality of cyclic bleeding as in endometriosis, adenomyotic lesions are also wounds that undergo ReTIAR, and we have recently provided evidence corroborating platelet-induced EMT, FMT and fibrogenesis in adenomyosis...

Antiphospholipid syndrome (APS) is characterized by thromboses and/or pregnancy losses. Laboratory criterion for the diagnosis of APS is the presence of antiphospholipid antibodies (anticardiolipin, anti-beta2-glycoprotein I (aβ2gpI) and lupus anticoagulant). On the one hand, the latest classification criteria for the diagnosis of APS emphasized that thrombotic manifestations of the syndrome should be without any signs of an inflammatory process, while on the other hand, some recent reports have suggested that APS is a "pro-inflammatory state...

Blood hemostasis is attained with two sophisticated interconnected network systems, a coagulation cascade and a platelet activation system. Multiple inhibitors were developed to various components of both systems to prevent thrombosis-related morbid events that are of extremely high frequency in the human population. Antithrombotic inhibitors possess both positive and negative aspects. One of the essential modern requirements is a controllable mode of action for both anticoagulants and antiplatelets that could be achieved due to the high affinity and specificity of the inhibitor, as well as a possibility to apply an antidote, which quickly annihilates activity of the inhibitor and restores the proper hemostasis...

SIOD is rare disorder related to SMARCAL1 or SMARCAL2 gene mutation, including (among other comorbidities) T-cell immunodeficiency, nephrotic syndrome, and renal failure. Up to 22% of primary patients may develop various autoimmune disorders. We report the case of 11-year-old male with SIOD, who presented ITP at 2 years after renal transplantation with decrease in platelet count (from normal) to 56 000/μL and then (gradually) to 2000/μL. There was no effect of iv. methylprednisolone/dexamethasone. As the presence of antibodies against GPIIb/IIIa, GPIb, and GPIaIIa platelet glycoproteins was confirmed, patient was given 50 g of IVIG and then was put on plasmapheresis; however, both showed poor direct effect...

Polyphenols are used as phlebotonic drugs, but their mechanism of action remains unknown. Since platelet activity and platelet-endothelial cell interactions are involved in the pathogenesis of cardiovascular disease, this work examines whether different flavonoid and coumarin drugs are able to inhibit platelet aggregation. This specific case of coumarins, the antiplatelet effect is not linked with a possible interaction over blood coagulation since this effect only dicoumarols have it. The antiplatelet capacity of polyphenols was assayed using peripheral blood platelets from healthy controls...

Pregnancy morbidity is part of the clinical spectrum of the anti-phospholipid syndrome (APS), with an important social and economical cost. Antiplatelet and anticoagulant agents are effective in preventing the clinical manifestations in the majority of the patients. However, a consistent proportion of the pregnant women present recurrences in spite of the standard therapy. Observational studies and anecdotal reports raised the issue of additional therapeutic strategies in these refractory cases. Among these, anti-malarials (AMs) and in particular hydroxychloroquine (HCQ) are becoming more and more popular in APS as well as in other systemic autoimmune rheumatic conditions...
