The purpose of this study was to determine the impact of the addition of factor (F)XIII on clot stability as assessed by Rotation Thromboelastometry (ROTEM). In 90 intensive care patients ROTEM measurements were performed after in vitro addition of F XIII IU, IU, IU and compared to diluent controls (DC; aqua injectabile Factor XIII (FXIII) is a transglutaminase enzyme that catalyses the formation of ε- (γ-glutamyl)lysyl isopeptide bonds into protein substrates. The plasma form, FXIIIA 2 B 2, has an established function in haemostasis, with fibrin being its principal substrate. A deficiency in FXIII manifests as a severe bleeding diathesis emphasising its Practice Essentials. Factor XIII (FXIII), which was initially termed fibrin stabilizing factor, is involved in clot preservation. FXIII also participates in other physiologic processes, including wound repair and healing. FXIII deficiency, an autosomal recessive disorder, is a rare but potentially life-threatening cause of a hemorrhagic diathesis LETS reported higher VTE risk in persons in the upper parts of the population distributions of factors IX, 2 X, 3 and XI, 4 but not factor XII. 5 Other reports suggest that factor XII deficiency is related to risk of first or recurrent thrombosis 6,, –9 although findings have been inconsistent. 5 An inverse association of factor XIII (activity and the Val 34
Factor XIII deficiency diagnosis: Challenges and tools
; doi/physrev—Factor XIII (FXIII) is unique among clot-ting factors for a number of reasons: 1) it is a protransglutaminase, which becomes activated Abstract. Multidisciplinary research from the last few decades has revealed that Factor XIII subunit A (FXIII-A) is not only involved in blood coagulation, but may have roles in various diseases. Here, we aim to summarize data from studies involving patients with mutations in the F13A1 gene, performed in FXIII-A knock-out mice models, clinical S: Although GPIIb/IIIa inhibition did not alter the results of the platelet-inhibited whole blood thrombelastography, factor XIII inhibition significantly reduced maximum clot firmness (P = ) and increased clot formation time (P = ) and clot lysis (P = ), leaving clotting time unchanged; a ceiling effect seemed to be present with increasing antibody Factor de coagulación XIII. El factor de coagulación XIII, factor XIII, factor estabilizador de la fibrina o factor de Laki-Lorand es una proteína plasmática de síntesis hepática y plaquetaria, que participa en la ruta final común de la hemostasia, estabilizando el coágulo blando de fibrina o polímero de fibrina Factor XIII Deficiency is an ultra-rare bleeding disorder. Bleeding disorders are a group of medical conditions that share an inability or decreased ability to form a stable blood clot. When the body is injured and an area bleeds, a clot is formed to stop the bleeding. Clot formation is a multistep process and is called coagulation. When the blood FXIII-A > % proved to be an independent risk factor for disease progression in NSCLC patients (OR=, 95% CI: , p = ), predicting poor efficacy. The marked decrease in plasma FXIII-A (FXIII-A coagulation disorders and poor prognosis with a short survival time (median survival Abstract. Coagulation factor XIII (FXIII) is converted by thrombin into its active form, FXIIIa, which crosslinks fibrin fibers, rendering clots more stable and resistant to degradation. FXIII affects fibrin clot structure and function leading to a more prothrombotic phenotype with denser networks, characterizing patients at risk of venous IV. THE ACTION OF ACTIVATED FACTOR XIII V.

INTRODUCTION The history of blood coagulation factor XIII (FXIII) started more than 70 years ago,

Factor XIII (FXIII) deficiency is a rare autosomal recessive disorder that can result in life-threatening bleeding and early fetal loss. FXIII not only is responsible for cross-linking fibrinogen to stabilize and strengthen clot formation but also facilitates wound healing and angiogenesis and plays an important role in fetal vitality. Modern therapeutics allow Factor XIII, an enzyme that cross-links fibrin, belongs to the blood coagulation system. [ 1, 2] Screening for factor XIII, also known as fibrin-stabilizing Abstract. The blood coagulation factor XIII (FXIII) plays a critical role in supporting coagulation and fibrinolysis due to both the covalent crosslinking of fibrin polymers, rendering them resistant to plasmin lysis, and the crosslinking of fibrin to proteins of the fibrinolytic system. The hypochlorite-mediated oxidation of the blood Factor XIII is a coagulation factor with multiple plasmatic and cellular functions part of which is outside of the field of traditional hemostasis. The aim of the review is to provide a brief summary on the relationship between coagulation factor XIII (FXIII) and the cells of the immune system. In the first part the structure and biochemical
