Association between Haptoglobin Groups and Aortic Abdominal Aneurysms

Abstract
Six different serum group systems (Bf, C3, Gc, Hp, Pi and Tf) were studied in a series of patients from northern Sweden with abdominal aortic aneurysms. In the haptoglobin system an increased frequency of the Hp 2–1 type was observed among the patients. No association was found between abdominal aortic aneurysms and the other five serum group systems.
