A five year experience of the use of factor IX type DE(I) concentrate for the treatment of Christmas disease of Oxford.
A survey is presented of the use of the Oxford type DE(I) II-IX-X concentrate in the treatment of Christmas disease in Oxford from January 1970 to September 1974. 72 different patients were treated with a total of 2436 bottles of this concentrate from 143 different batches (each bottle containing 800-1000 units of factor IX). Although most doses were given for the treatment of minor haemorrhages into joints and muscles, 717 bottles of concentrate were used to treat 11 patients who underwent 14 major surgical operations. No episode of intravascular clotting or pulmonary embolism was seen in any patient receiving the concentrate. A detailed study of the plasma levels of factor V, VIII, total progressive antithrombin, platelets and fibrinogen degradation products was carried out before and after transfusion of type DE(I) concentrate in 14 patients. No significant alteration in those factors was found after the transfusion.
