Turnover of alpha-2-antiplasmin in patients with acute promyelocytic leukemia
Patients with acute promyelocytic leukemia have a bleeding disorder which was thus far explained by a coagulopathy based on diffuse intravascular coagulation (DIC). We observed severe alpha-2-antiplasmin deficiency in a consecutive series of such patients. We postulate proteolysis rather than DIC, also because of increased turnover of 125I-alpha-2-antiplasmin, to be responsible for the coagulopathy. Alpha-2-antiplasmin deficiency may well contribute to the bleeding disorder in acute promyelocytic leukemia.
