Pseudo-factor-XI deficiency: effect of an inhibitor of factor XI adsorption to surface.
Recently we have described a normal plasma activity that modulates contact activation by inhibiting adsorption of factor XI to activating surfaces. Here we report the first identified case in which a patient has abnormal clotting tests due to an excess of a similar activity. The patient's plasma had a prolonged partial thromboplastin time and low apparent factor XI assay. His plasma prolonged t...
متن کاملFactor XI deficiency.
That factor XI has a role in normal blood coagulation is evidenced by the fact that patients with deficiency are prone to excessive bleeding after haemostatic challenge. The role of factor XI in physiological processes has become clearer since the discovery that it is activated by thrombin; this fact has contributed to a revised model of blood coagulation. Factor XI deficiency is particularly c...
متن کاملFactor XI activity and factor XI antigen in homozygous and heterozygous factor XI deficiency.
A relatively potent antiserum against highly purified, unactivated human factor XI antigen was raised in a rabbit. This antiserum, after concentration, neutralized 50% of the factor XI clotting activity of a standard normal plasma at an antiserum dilution of 1/900. The antiserum was used in a neutralization-inhibition assay to study the relation between factor XI clotting activity and factor XI...

متن کاملPrevalence, causes, and characterization of factor XI inhibitors in patients with inherited factor XI deficiency.
Factor XI deficiency, an injury-related bleeding disorder, is rare worldwide but common in Jews in whom 2 mutations, Glu117Stop (type II) and Phe283Leu (type III), prevail. Mean factor XI activities in homozygotes for Glu117Stop and for Phe283Leu are 1 and 10 U/dL, respectively. Inhibitors to factor XI in patients with severe factor XI deficiency have been reported in a small number of instance...
