Haemophilia, 1998
Summary. The immunogenicity of factor VIII depends on the interaction of multiple parametres including host susceptibility and characteristics of the factor VIII preparations. We briefly review here the basic mechanisms by which tolerance to self is established, maintained, and possibly broken in the context of haemophilia A, with special emphasis on ...

New approaches and techniques for improving source material collection and factor VIII production at Blood Bank level have been reported recently. Heparin has shown to be of great importance in increasing both yield and stability of factor VIII in the purification and concentration process.

FACTOR VIII AND GLOMERULONEPHRITIS
The Lancet, 1975To find out if determination of factor VIII,which most probably is synthetised in the intima of blood-vessesls, is of value for predicting the severity of vessel damge in glomerulonephritis, factor-VIII activity, factor-VIII-related antigen, and glomerular filtration-ratewere esto,ated om 85 patients with early glomerulonephritis on admission, and in ...

Factor VIII activity and factor VIII related antigen in newborns
European Journal of Pediatrics, 1978Factor VIII procoagulant activity and factor VIII related antigen were examined in 20 full-term and preterm newborn infants during the first days of life. The control group involved 15 adults volunteers. Factor VIII activity was estimated by a one-stage test and factor VIII related antigen was determined by immunelectrophoresis according to Laurell ...

In Vivo Interactions of Autoantibodies to Factor VIII with the Factor VIII Complex
Thrombosis and Haemostasis, 1982SummaryTwo non-haemophilic elderly patients who had developed autoantibodies to factor VIII were studied over a period of 9 months to 5 years. Sequential measurements of antibody to factor VIII (anti-VIII: C), factor VIII coagulant activity (VIII: C), factor VIII coagulant antigen (VIII: CAg), factor VIII-related antigen (VIIIR: Ag), and factor VIII ...

Scandinavian Journal of Haematology, 1980
Because of the need to relate haemophilic samples to the normal population, the unit of Factor VIII clotting activity (VIII:C) was first defined as the amount in 1 ml. of normal plasma. However, because of wide variation in the normal population, and poor stability of VIII:C in plasma, pooled normal plasma is unsuitable as a reference standard for ...

The differential diagnosis in the bleeding patient includes inhibitory antibodies to blood coagulation proteins. Factor VIII (fVIII) is the most commonly targeted coagulation protein by the immune system. FVIII inhibitors arise as alloantibodies in transfused hemophiliacs and as autoantibodies in nonhemophiliac populations (1, 2, 3, 4). They develop in

To the Editor.— Rock et al 1 reported that in studies in 1982, the stated content of ampules of lyophilized antihemophilic factor (AHF, factor VIII) concentrates often exceeded the measured content, as assayed in the authors' laboratory. They stated that this discrepancy, with its implications of systematic undertreatment of classic hemophilia, has ...

Activation, activity and inactivation of factor VIII in factor VIII products
Haemophilia, 2016IntroductionFactor VIII (FVIII) products used in haemophilia A treatment show inter‐and intra‐product and inter‐assay differences in specific activity. The mechanistic basis of these differences remains unclear.AimThe aim of this study was to mechanistically compare the functional properties of an in‐house excipient‐free full‐length FVIII standard and ...

To the Editor.— Dr Waddell and colleagues 1 described the use of porcine factor VIII concentrate in a patient with factor VIII inhibitor. They gave in detail the disadvantages and complications of this material and prothrombin complex concentrates.
