Abstract Coagulation factor XIII (FXIII) is converted by thrombin and Ca (2+) into an active transglutaminase (FXIIIa) in the final phase of coagulation cascade. Its main function is the mechanical stabilization of fibrin clot and its protection from fibrinolysis by cross-linking of fibrin chains and α (2)-plasmin inhibitor to fibrin.
Inherited factor XIII deficiency (FXIIID) is a rare bleeding disorder affecting the final stage of the coagulation system and resulting in a bleeding diathesis. 1 The worldwide incidence of FXIIID, inherited as an autosomal recessive disorder, is approximately one per 1‐3 million people. Its prevalence depends on geographic region and is higher in areas in which DOI 10.1515/cclm-2011-0730 Review Measurement of factor XIII activity in plasma Éva Katona1, Krisztina Pénzes1, Éva Molnár1 Introduction and László Muszbek1,2,* 1 Coagulation factor XIII (FXIII) is a zymogen of tetra- Clinical Research Center, University of Debrecen, Medical meric structure (FXIII-A2B2) that consists of two catalytic and Health Science Center, Debrecen, Hungary 2 A 2014-07-01 Plasma factor XIII is a tetrameric molecule composed of 2 A-subunits of 83.2 kd and 2 B-subunits of 79.7 kd that are held together noncovalently in a heterologous tetramer of 325.8 kd.1-3 In addition, 50% of the total fibrin-stabilizing activity in blood is found in the platelet where factor XIII exists as a dimeric molecule composed of only A-subunits.4 The A-subunit contains the active site Factor XIII is activated by thrombin in the presence of calcium which leads to the release of the activation peptide, followed by the dissociation of carrier subunits. The activated Factor XIII (XIIIa) acts on fibrin (Factor Ia) to form γ-glutamyl-Є-lysyl amide cross links between fibrin molecules leading to the formation of an insoluble clot. 2021-03-09 Factor XIII Activity 69-143%.

F XIII activity was the only coagulation factor continuously declining during vvECMO, being significantly decreased at T3 (31% (26/45) vs. 24% (18/42), p = 0.0079) and T7 (31% (26/45) vs. 23% (17/37), p = 0.0037) compared to T0. Background: The aim was to evaluate factor XIII activity (FXIIIa) and monocyte-derived microparticles (MDMPs) in cancer patients. Methods: In total, 138 cancer patients (31 malignant lymphomas, 39 multiple myelomas, and 68 lung cancers) were analyzed. Activated factor XIII (FXIIIa) mediates fibrinolytic resistance and is a hallmark of newly formed thrombi. In vivo imaging of FXIIIa activity could further elucidate the role of this molecule in Se hela listan på en.wikipedia.org Factor XIII Activity 69-143%. Rejection Criteria.
Plasma factor XIII (fibrin-stabilizing factor; FSF) zymogen consists of 2 "A" and 2 "B" subunits, the "A" subunits containing an active-center sulfydryl grouping mediating the transamidase activity of the enzyme.

This test also indicates those patients who have a genetic bleeding disorder which is caused due to factor xiii deficiency. Blood coagulation factor XIII (FXIII), also known as fibrin stabilizing factor, is a transglutaminase precursor that acts at the final stage of the blood coagulation Factor XIII (13) Activity – Quantitative: 1 week: No: citrated plasma: Fibrinogen Activity: 24 hours: No: citrated plasma: Fibrinogen Antigen: 1 week: No: citrated plasma: Fondaparinux (Arixtra) Level: 24 hours: No: citrated plasma: Dabigatran (Pradaxa) Level: 24 hours: No: citrated plasma: Euglobulin Clot Lysis Time: 1 week: No: citrated plasma: Factor II (2) Activity: 24 hours: No: citrated plasma Factor XIII is a transglutaminase, which is important in the cross-linking of the fibrin framework of the clot. Plasma factor XIII is activated when it is cleaved by thrombin. This changes its configuration in such a way so as to expose an active site that can bind to fibrin leading to cross-linking. The objective of this study was to investigate the correlation between factor XIII (FXIII) activity and disseminated intravascular coagulation (DIC) parameters and also to evaluate the clinical usefulness of DIC diagnosis.

The primary patient conditions (48 Intracellular Factor XIII including platelet Factor XIII comprises only the FXIII-A subunits and exists as a homodimer of the A subunit [FXIII-A 2]. Factor XIII has a number of other functions in addition to the stabilisation of the Fibrin clot and these include the maintenance of pregnancy, bone/cartilage growth and wound healing.
