AI Article Synopsis

  • Platelets are crucial for stopping bleeding (haemostasis) and their dysfunction can lead to hemorrhagic or clotting disorders (thrombocytopathies).
  • The review discusses traditional issues with platelets, including how they stick to each other and release chemicals in the blood.
  • It emphasizes the importance of studying procoagulant platelets—those that help blood clotting—when investigating potential platelet-related diseases.

Article Abstract

Platelets are active key players in haemostasis. Qualitative platelet dysfunctions result in thrombocytopathies variously characterized by defects of their adhesive and procoagulant activation endpoints. In this review, we summarize the traditional platelet defects in adhesion, secretion, and aggregation. In addition, we review the current knowledge about procoagulant platelets, focusing on their role in bleeding or thrombotic pathologies and their pharmaceutical modulation. Procoagulant activity is an important feature of platelet activation, which should be specifically evaluated during the investigation of a suspected thrombocytopathy.

Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a rare but serious prothrombotic adverse event following vaccination with adenovector-based COVID-19 vaccines. Laboratory findings indicate that anti-platelet factor 4 (PF4) immunoglobulin G antibodies are the causing factor for the onset of thromboembolic events in VITT. However, molecular mechanisms of cellular interactions, signaling pathways and involvement of different cell types in VITT antibody-mediated thrombosis are not fully understood.

Modulation of Haemostatic Balance in Combined von Willebrand Disease and Antithrombin Deficiency: A Comprehensive Family Study.

Haemophilia

Institute of Experimental Hematology and Transfusion Medicine, Medical Faculty, University Hospital Bonn, University of Bonn, Bonn, Germany.

Introduction: Maintaining the balance between procoagulant and anticoagulant factors is essential for effective haemostasis. Emerging evidence suggests a modulation of bleeding tendency by factors in the anticoagulant and fibrinolytic systems.

Aim: This study investigates the clinical and laboratory characteristics of a family with combined von Willebrand disease (VWD) and antithrombin (AT) deficiency.

Electronic address:

Background & Aims: Venous thromboembolism is a serious complication during and following hospitalization with acute severe ulcerative colitis (ASUC). We evaluated serial thrombotic profiles of patients with ASUC from the point of hospitalization up to 12 weeks post-discharge and compared these with control patients with quiescent UC.

Methods: Twenty-seven patients with ASUC and 25 control patients with quiescent ulcerative colitis (UC) were recruited.

Impaired Hemostatic and Immune Functions of Platelets After Acute Thrombocytopenia.

J Thromb Haemost

December 2024

Institute of Vascular Biology and Thrombosis Research, Center of Physiology and Pharmacology, Medical University of Vienna, Vienna, Austria. Electronic address:

Background: Platelets are pivotal in maintaining vascular integrity, hemostasis, and immune modulation, with newly generated, immature platelets being the most responsive in fulfilling these tasks. Therefore, the immature platelet fraction provides insights into thrombopoiesis dynamics and clinical prognostication. However, it is currently unclear how immature platelet functions change in settings of acute thrombocytopenia.

Background: Enzymatically oxygenated phospholipids (eoxPL) from lipoxygenases (LOX) or cyclooxygenase (COX) are pro-thrombotic. Their generation in arterial disease, and their modulation by cardiovascular therapies is unknown. Furthermore, the Lands cycle acyl-transferases that catalyze their formation are unidentified.
