ABO blood groups and serum proteins in thromboangiitis obliterans (Buerger's disease).

In Madhya Pradesh, India, 43 patients with thromboangiitis obliterans showed a decrease in total serum proteins and in the albumin fraction, an increase in a1-and a2-globulin fractions, and decrease in the albumin/globulin ratio. In the ABO blood groups, patients show a significant excess of group B individuals. It is possible that the disease may be more severe in individuals with the B blood group substance.
