Recently, a pure factor IX concentrate, licensed in Sweden as Immunine, was prepared through ion exchange and hydrophobic chromotography. Virus inactivation included two steps of steam treatment. Reconstituted Immunine could be kept at room temperature for at least 7 days without any substantial loss of activity. A patient with moderate hemophilia B undergoing bilateral total hip replacement was continuously infused with Immunine by use of a pump. There were no bleeding complications or signs of thrombosis, and the operation markedly improved the patient's range of motion and quality of life.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
