It was agreed to test whether other haemophilia nurses perceived such a need by means

of a short five-item questionnaire devised by the group and made available to all members of the UK’s Haemophilia Nurse’s Association via Survey-Monkey. Final responses from 59 haemophilia nurses across the UK have MK-1775 supplier been analysed. Most nurses agreed that there was value in the development of a haemophilia link nurse role within UK hospitals and thought their trusts would support it. While barriers and potential downsides were acknowledged, this was seen as a useful way of sharing information and knowledge with colleagues from different specialties and of raising awareness of bleeding disorders among the general nursing community. Haemophilia nurses should coordinate the development of a Haemophilia Link Nurse training and education PI3K inhibitor pack. “
“Summary.  Bleeding disorders secondary to acquired non-inhibitory antibodies directed against vitamin K-dependent coagulation proteins are rare. In this report, the authors describe a patient with a low grade lymphoma who presented with a fatal acquired bleeding manifestation and abnormal

hemostatic studies resulting from deficiencies in both prothrombin and factor X. Patient plasma samples were collected and studied for the presence of an acquired inhibitor. Levels of plasma coagulation proteins were measured using immunoassay. Patient anti-prothrombin immunoglobulin G was isolated and binding to prothrombin, prothrombin F1.2, factors IX and X was evaluated using immunoblots and competition immunoassay.

Prolongation in the prothrombin time and activated partial thromboplastin time suggested a factor deficiency in the common pathway of coagulation. Functional and antigenic levels of both prothrombin and factor X were decreased. An IgG subtype-4 antibody was isolated from patient plasma using affinity chromatography on prothrombin-sepharose. This antibody was found to bind to a common metal-ion-dependent conformational epitope found on the γ-carboxyglutamic acid (Gla) domain of prothrombin, factor X and factor IX. This report represents the first description of an acquired bleeding disorder resulting selleck inhibitor from a unique cross-reactive auto-antibody against a common metal-ion-dependent antigenic structure on the Gla-domain of the vitamin K-dependent proteins. “
“Summary.  Cranial haemorrhage (CH) is a potentially serious complication in patients with severe congenital haemophilia with inhibitors (CHwI). Treatment includes bypassing agents, such as recombinant activated factor VII (rFVIIa). To examine the US experience in treating CH with rFVIIa, a retrospective review of the Hemophilia and Thrombosis Research Society 2004–2008 database was conducted.
