Prothrombotic coagulation abnormalities in patients with newly diagnosed multiple myeloma

Prothrombotic coagulation abnormalities were analyzed in patients with untreated multiple myeloma. Increases in factor VIII, in von Willebrand factor and a decrease in protein S were observed and these changes were strongly associated with disease stage. No difference in baseline coagulation parameters was found between patients with and without subsequent venous thromboembolism.
