説明

Activated protein C resistance (APC-R) has recently been reported to be the most common hereditary blood coagulation disorder associated with familial thrombosis. APC-R is characterized by a poor anticoagulant response to APC in the plasma of patients the and is due to a defect of factor V. However, all the data relating to APC-R have been derived from Westerners, and little information is yet available on APC-R in Japan. We therefore studied 82 patients suffering from stroke and 33 patients with neurological disease who remained free of vascular disease, by measuring the activated partial thromboplastin time (aPTT) with and without addition of APC. We also determined whether a mutation (Arg506→ Gln) of the factor V gene was present or absent. All patients revealed an APC ratio within the normal range, and the mutation was absent in all of them. We conclude that the incidence of APC-R is very low in Japan.
