Abstract

Increased α2-macroglobulin (α2M) activity and concentration, and decreased antithrombin III (ATIII) plasma concentration are reported in diabetic subjects. In diabetes an inverse correlation between ATIII activity and blood glucose, HbA1. α2M activity and α2M concentration, and a direct correlation between both α2M concentration with blood glucose and HbA1 are found. Moreover, a direct correlation between α2M activity and α2M concentration fails. In both diabetic and normal subjects induced hyperglycemia increases α2M activity and α2M concentration reduces ATIII activity, while ATIII concentration is not affected. These data which show that hyperglycemia may increase α2M molecule levels while altering only the biological function of ATIII, provide evidence that hyperglycemia may decrease, directly, the biological function of some proteins and may condition the levels of some risk factors for the development of diabetic complications such as α2M.
