Anti-beta2-Glycoprotein I antibody and hypertension in cerebral ischemia.
Hypertension is known as a cause of endothelial cell damage and it activates humoral immunity. Therefore, it may modulate the anti-beta2-glycoprotein I antibody (abetaGPI) to commit for thrombosis. To elucidate the relation between abetaGPI and hypertension in cerebral ischemia, the blood abetaGPI level was examined in healthy subjects, hypertensive subjects, and patients with cerebral ischemia with and without hypertension, respectively. The results showed that the blood abetaGPI level increased in cerebral ischemia patients with hypertension rather than hypertensive subjects, and patients without hypertension rather than healthy individuals. However, the blood abetaGPI level showed no difference between healthy individuals and hypertensive subjects, nor cerebral ischemia patients with and without hypertension. The serum globulin level did not change among them. Therefore, abetaGPI displays a vital role for cerebral ischemia in both hypertensive and normotensive subjects. An activation of humoral immunity involving abetaGPI warrants further investigation in cerebral ischemia.
