Prediction of Disseminated Intravascular Coagulation in Patients with Leukemia.

In 43 patients with leukemia, we determined the increase of tissue factor (TF) activity production by leukemic cells that was induced by incubation with endotoxin at the time of admission. Definite disseminated intravascular coagulation (DIC) developed in 8 patients on admission (Group III) and in 8 patients just after the initiation of treatment (Group II), but not in the remaining 27 patients (Group I). TF activity before incubation (TF1) was 0.70 U/108 cells or more in 6 patients of Group III, while it was less in all the patients of Group II and 25 of the 27 patients of Group I. On the other hand, TF activity after incubation with endotoxin (TF2) increased to more than 1.11 U/108 cells in all the patients of Groups II and III, while it remained less in all the patients of Group I. These results suggest that the leukemic cells in Group II might not have expressed sufficient TF activity to cause DIC until chemotherapy was begun, and that 1.11 U/108 cells or more of TF2 might strongly indicate the development of DIC during treatment for leukemia.(Internal Medicine 33: 131-135, 1994)
