Circulating anticoagulant against factor XII in smoldering leukemia. 1982

J R Duran-Suarez, and M Vila, and S Rodriguez-Bueno, and J Triginer

A circulating anticoagulant against factor XII was detected in a patient with smoldering leukemia. Despite severe associated thrombocytopenia the patient suffered two thromboembolic episodes, besides mucosal bleeding. The circulating anticoagulant was demonstrated not only in the plasma but also in the serum. Its activity was not affected by heating at 56 degrees C for 30 min and it was not adsorbed by SO4Ba or A1(OH)3. The circulating anticoagulant was not dializable and demonstrated to be an IgG. This is apparently the first reported association of smoldering leukemia and a circulating anticoagulant against factor XII.

D007938	Leukemia	A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells.
