Central venous access device‐related infections in patients with haemophilia
ConclusionCVAD‐related infection in this Australian population was comparable to rates described in the medical literature. Ongoing surveillance for infection rates is important to provide an up‐to‐date assessment of risks associated with CVAD use in this population. (Source: Journal of Paediatrics and Child Health)

The effect of secondary prophylaxis versus episodic treatment on the range of motion of target joints in patients with haemophilia
This study prospectively compared the effect of secondary prophylaxis to episodic treatment on target joint (TJ) range of motion (ROM), number of joint haemorrhages and new TJ development in patients with moderate or severe haemophilia. Two‐hundred and eighty‐six males, 17% in prophylaxis, 83% in episodic treatment group, participating in the Centers for Disease Control and Prevention's Universal Data Collection project, fulfilled inclusion criteria: age >2 years at enrolment, free of TJs at enrolment, developed at least one TJ after enrolment, and received either prophylaxis or episodic treatment continuously for ...

Alloantibodies against the B subunit of plasma factor XIII developed in its congenital deficiency.
Abstract Factor XIII (FXIII) is a fibrin-stabilising factor consisting of catalytic A subunits (FXIII-A) and carrier B subunits (FXIII-B). FXIII-B prevents the fast clearance of FXIII-A from the circulation. Congenital FXIII-A deficiency is a rare bleeding disorder, and congenital FXIII-B deficiency is even rarer. Through our recent nationwide survey on "acquired haemophilia-like disease due to anti-FXIII autoantibodies," we newly diagnosed severe congenital FXIII-B deficiency in a Japanese man. He developed thrombocytopenia and gingival bleedings at the age of 73, and his FXIII activity was as low as 10% of the no...

Enhancing the pharmacokinetic properties of recombinant factor VIII: First‐in‐man trial of glycoPEGylated recombinant factor VIII in patients with hemophilia A
ConclusionsA single dose of up to 75 U/kg N8‐GP was well tolerated in patients with hemophilia A, with no safety concerns. N8‐GP had a prolonged half‐life and FVIII:C activity remained above 1% for a longer compared with the patient's previous product. These results indicate that N8–GP has the potential to reduce dosing frequency during prophylaxis.© 2013 International Society on Thrombosis and Haemostasis (Source: Journal of Thrombosis and Haemostasis)

Platelet activation and aggregation: the importance of thrombin activity. A laboratory model
This study introduces a new laboratory model of whole blood platelet aggregation stimulated by endogenously generated thrombin, and explores this aspect in haemophilia A in which impaired thrombin generation is a major hallmark. The method was established to measure platelet aggregation initiated by tissue factor evaluated by means of impedance aggregometry. Citrated whole blood from healthy volunteers and haemophilia A patients with the addition of inhibitors of the contact pathway and fibrin polymerization was evaluated. In healthy persons, a second wave of platelet aggregation was found to coincide with the thrombin bur...

Cytokine profile and FVIII inhibitors development in haemophilia A
This study investigated the immunological cytokine profile using plasma from HA patients which were either positive or negative for FVIII inhibitors and from healthy individuals. The results showed that healthy individuals and HA patients that do not develop FVIII inhibitors have a mixed immune response profile with high secretion of IFN‐γ, TNF‐α IL‐2 and IL‐5. In contrast, HA patients with FVIII inhibitors exhibited an anti‐inflammatory/regulatory immune response characterized by low levels of all measured cytokines except for IL‐4 and IL‐10. This profile may be related to the development and maintenance o...

Novel coagulation factor concentrates: Issues relating to their clinical implementation and pharmacokinetic assessment for optimal prophylaxis in haemophilia patients
Summary Prophylaxis is considered the optimal treatment regimen for patients with severe haemophilia, and may be especially important in the prevention of joint disease. Novel coagulation factor concentrates with prolonged half‐lives promise to improve patient treatment by enabling prophylaxis with less frequent dosing. With the call to individualize therapy in haemophilia, there is growing awareness of the need to use pharmacokinetic (PK) assessments to tailor prophylaxis. However, for new factor concentrates, it is not yet known which PK values will be most informative for optimizing prophylaxis. This topic was explore...

Treatment of refractory hemorrhage with factor XIII in a patient with hemophilia A with inhibitor
Abstract An 11‐year‐old male with hemophilia A and a known high‐titer Factor VIII inhibitor was admitted with retroperitoneal hemorrhage. The patient was receiving infusions of recombinant activated Factor VII (rFVIIa) for a recent elbow hemorrhage when retroperitoneal bleeding commenced. Despite increased dosing of rFVIIa and a dose of activated prothrombin complex concentrate (aPCC), he continued to hemorrhage and required several blood transfusions. Factor XIII was administered 1 hour after rFVIIa and the patient demonstrated cessation of bleeding and normalization of clot strength. Factor XIII may act as an adj...

Incidence, mortality rates and causes of deaths in haemophilia patients in Sweden
Summary Sweden has been a pioneer in the treatment of haemophilia, with the first concentrate available in the 1950s. Treatment has improved over the years to its current state‐of‐the art. The aim of the current study was to evaluate the long‐term outcome of haemophilia in terms of incidence, morbidity and mortality. Patients diagnosed with haemophilia A or B registered at the national haemophilia centres and/or the Patient Registry and born before 2009 and alive in 1968 were enrolled and linked to the Cause of Death‐, Migration‐ and Medical Birth registries. Five age‐ and sex‐matched controls were selected f...

Practical and cost‐effective measurement of B‐domain deleted and full‐length recombinant FVIII in the routine haemostasis laboratory
The objective of this study was to facilitate the measurement of rFVIII, taking into account the recent demonstration that a calibration curve does not have to be included in each run. FVIII:C was measured in patients' samples after infusion of different types of rFVIII with a one‐stage and a chromogenic assay calibrated either with pooled normal plasma or a product‐specific laboratory standard. Results obtained with the one‐stage coagulation assay were compared with these provided by a chromogenic assay. We confirmed that a calibration curve can be used for a prolonged period of time without loss of precision and ac...

How I manage patients with acquired haemophilia A
Summary Acquired haemophilia A (AHA) is a potentially life‐threatening bleeding disorder occurring in patients without a previous personal or family history of bleeding. Development of immune‐mediated autoantibodies against coagulation factor VIII is associated with a wide range of clinical disorders including pregnancy, autoimmune disorders, malignancy, or with no apparent disease. There exists great potential for morbidity and mortality related to acute and recurrent bleeding episodes, making prompt diagnosis and treatment necessary. The two primary goals of treatment focus on cessation of bleeding and eradication of...

Abstract Although the incidence of haemophilia A is reportedly uniform across ethnic groups, the prevalence varies in different countries. This suggests variability in the effectiveness of diagnostic strategies which is of particular importance in the recognition of milder forms of the disease. To assess the different laboratory tests that are used in the diagnosis and subsequent management of haemophilia A we carried out a web-based survey of established haemophilia centres. This was sent to 13 haemophilia physicians from haemophilia-treatment centres in Germany, Italy, Spain, South Africa, Taiwan, Norway, Canada,...

Plasmatic tissue factor pathway inhibitor is a major determinant of clotting in factor VIII inhibited plasma or blood.
Abstract Tissue factor pathway inhibitor (TFPI) is a major inhibitor of coagulation. We therefore hypothesised that high plasmatic TFPI levels are associated with impaired ex vivo clotting in a model of acquired haemophilia. Blood samples were collected in a prospective clinical study from 30 healthy volunteers. Coagulation in normal or factor VIII (FVIII)-inhibited human blood or plasma was measured by the calibrated automated thrombogram (CAT) and rotational thromboelastometry (ROTEM). Both methods are global haemostatic assays that provide insight into the whole coagulation process. Monoclonal mouse antibodies r...
