Background: Nephrotic syndrome (NS) is a common kidney disease associated with an increased risk of thrombotic events. The aim of this study was to assess the prothrombotic potential of patients with NS using the thrombin generation assay (TGA).
Methods: A total of 35 patients with NS, who were followed in the Division of Pediatric Nephrology in Behcet Uz Children`s Hospital, were included in the study. After the patients with Steroid Resistant NS (n:3) were excluded, 32 patients in total were evaluated for TGA. Patients were primarily classified according to their response to corticosteroid therapy. The control group consisted of 34 healthy volunteers with similar gender and age distribution to the patients. Blood urine nitrogen, creatinine, albumin, triglyceride, cholesterol, 24-hour proteinuria, platelets, erythrocyte sedimentation rate, C-reactive protein and thrombin generation values in activation and remission period of NS were compared. Moreover, TGA values of the patients in their remission period were compared with the values of those in the control group.
Results: Endogenous thrombin potential (ETP) and peak thrombin levels were significantly higher in the activation period than remission period of NS. Additionally, after the patients achieved remission, their ETP was still higher than the control group. There was a negative correlation between both ETP and peak thrombin levels of patients with serum albumin, whereas a significant positive correlation was detected with platelet levels. Thromboembolic events were not observed in any of the patients during follow-up.
Conclusions: Nephrotic syndrome is strongly associated with hypercoagulopathy as assessed by TGA during active NS. The present study reinforces the usefulness of TGA as a marker of hypercoagulability in pediatric patients with NS. Further studies are needed in this regard.

Background: Inflammation is a driver of thrombosis, but the phenomenon of thromboinflammation has been defined only recently, bringing together the multiple pathways involved. models can support the development of new therapeutics targeting the endothelium and also assess the existing immunomodulatory drugs, such as hydroxychloroquine, in modulating the inflammation-driven endothelial prothrombotic phenotype.
Objectives: To develop a model for thrombin generation (TG) on the surface of human endothelial cells (ECs) to assess pro/antithrombotic properties in response to inflammation.

In this article, our goal is to offer an introduction and overview of the diagnostic approach to inherited platelet function defects (iPFDs) for clinicians and laboratory personnel who are beginning to engage in the field. We describe the most commonly used laboratory methods and propose a diagnostic four-step approach, wherein each stage requires a higher level of expertise and more specialized methods. It should be noted that our proposed approach differs from the ISTH Guidance on this topic in some points.

Red blood cells (RBCs) serve as natural transporters and can be modified to enhance the pharmacokinetics and pharmacodynamics of a protein cargo. Affinity targeting of Factor IX (FIX) to the RBC membrane is a promising approach to improve the (pro)enzyme's pharmacokinetics. For RBC targeting, purified human FIX was conjugated to the anti-mouse glycophorin A monoclonal antibody Ter119.

Antibodies to β2-glycoprotein I (β2GPI) cause thrombosis in antiphospholipid syndrome, however the role of β2GPI in coagulation in vivo is not understood. To address this issue, we developed β2GPI-deficient mice (Apoh-/-) by deleting exon 2 and 3 of Apoh using CRISPR/Cas9 and compared the development of thrombosis in wild-type (WT) and Apoh-/- mice using rose bengal and FeCl3-induced carotid thrombosis, laser-induced cremaster arteriolar injury, and inferior vena cava (IVC) stasis models. We also compared tail bleeding times and activation of platelets from WT and Apoh-/- mice in the absence and presence of β2GPI.

Background: Extracellular vesicles (EVs) have procoagulative properties. As EVs are known to accumulate in stored blood products, we compared the EV content and coagulation capacity of leukoreduced cold-stored whole blood (CSWB) with current prehospital and in-hospital component therapies to understand the role of EVs in the haemostatic capacity of ageing CSWB.
Materials And Methods: Blood was obtained from 12 O RhD-positive male donors.
