Factor XIII deficiency does not prolong the PT or aPTT (recall that factor XIII crosslinks fibrin but the PT and aPTT reaction endpoint is the formation of fibrin and these tests do not measure the effect of factor XIII).

Factor XI deficiency, hemophilia C, is autosomal recessive and is most common in Ashkenazi Jews, though it may be found in any ethnic group. The intensity of hemophilia C bleeding correlates poorly with factor XI activity. 6. Fibrinogen deficiency prolongs both PT and PTT, but only when the concentration is < 100 mg/dL.

Factor XIII is a transglutaminase enzyme that crosslinks the γ-chains of two D-domains of fibrin (creating the neo-epitope, D-dimer in the process and forming a stabilized longitudinal fibrin polymer) and the α-chains of two adjacent fibrin polymers, forming a laterally (cross-sectionally) stabilized fibrin network. Heterozygous factor XII deficiency is present in 2% of normal people. From laboratory experience, I’ve found the PTT to be relatively sensitive to moderate factor XII deficiency, owing to its presence at the top of the intrinsic coagulation mechanism. The diagnosis of haemophilia A may be suspected as coagulation testing reveals an increased partial thromboplastin time (PTT) in the context of a normal prothrombin time (PT) and bleeding time.

Frontiers | Hemostatic Challenges in Pediatric Critical Factor XIII deficiency is a congenital disorder that is inherited as an autosomal recessive trait and is associated with a variable bleeding tendency Acquired factor XIII deficiency is associated with liver failure, inflammatory bowel disease, leukemia, disseminated intravascular coagulation, Henoch-Schonlein purpura, systemic lupus erythematosus and exposure to certain drugs (phenytoin, isoniazid, valproate) Factor XIII deficiency is a rare autosomal recessive congenital deficiency. Factor XIII plays an important role in the cross-linking of polymerized fibrin. Patients present with bleeding and delayed wound healing usually first noted at the umbilical stump or after circumcision. They have normal PT and aPTT tests but increased clot solubility.

Abstract. Background: Factor XIII (FXIII) deficiency is a severe bleeding disorder with normal routine coagulation tests that makes diagnosis of the disorder complicated. After normal results in routine coagulation tests, clot solubility test, and FXIII activity, antigen assays along with molecular methods can be used for precise diagnosis of disorder. Factor XIII deficiency is a rare, genetic bleeding disorder characterized by deficiency of clotting factor XIII.

If clot is easily lysed in 5 (M) urea solution then unstable clot and factor-XIII deficiency is confirmed. 2019-03-15 · Results from standard hemostatic screening tests such as activated partial thromboplastin time (aPTT) and international normalized ratio (INR) assessments are normal in factor XIII (FXIII) Deficiency of factor VIII, IX, or XI: Deficiency of factor XII, prekallikrein, or HMW kininogen (not associated with a bleeding diathesis) von Willebrand disease (variable) Acquired: Heparin, dabigatran, argatroban, direct factor Xa inhibitors (variable)* Acquired inhibitor of factor VIII, IX, XI, or XII: Acquired von Willebrand syndrome Prolonged PT, prolonged APTT: Multiple factor deficiencies, affecting both factor VII (see list above) and intrinsic pathway factors (XII, XI, IX, X) or common pathway factor deficiencies. This can be due to multiple causes, including inherited factor X deficiency or acquired defects such as vitamin K deficiency or antagonism, DIC, liver failure and hypofibrinogenemia.

Abstract. Acquired factor XIII (FXIII) deficiency is a rare bleeding disorder that can manifest with spontaneous or delayed life-threatening hemorrhage. Causes of acquired deficiency include immune-mediated inhibition, as well as non-immune FXIII hyperconsumption or hyposynthesis. The occurrence of acquired FXIII deficiency can be idiopathic or may be associated with comorbidities, such as malignancies or autoimmune disorders.

Its deficiency results in prolonged PT and PTT. deficiencies. Factor XIII (fibrin-stabilizing factor): Synthesized in the liver; also present in platelets. The PT is an in vitro measure of the "extrinsic" pathway of coagulation, stimulated by tissue thromboplastin. The PTT is affected initially by specific factor deficiencies, such as hemophilia, or Heparin therapy. Factor inherited or acquired FXIII de ciency. Appropriate for evaluation of individuals with a bleeding disorder who present with normal PT, PTT, and platelet count test .
