Key parameters of carbohydrate metabolism in healthy people with different AB0 blood groups

Aim. To study the particularities of metabolism associated with AB0 system blood groups by examination of carbohydrate exchange serum parameters. Methods. 446 healthy subjects with different blood groups were examined: 0 (I) blood group - 29.6%, A (II) - 31.8%, B (III) - 24.3%, AB (IV) - 14.3%. The blood group was defined by direct agglutination test in all subjects, piruvate, lactate, glucose, cortisol and insulin serum levels, lactatdehydrogenase and α-аmylase activity was defined using an automatic biochemical analyzer. Results. Group specific features of carbohydrate metabolism in subjects with different blood groups were revealed. In subjects with 0 (I) blood group the lowest glucose and insulin serum levels, the highest amylase activity and piruvate and lactate blood levels were characteristic; in subjects with A (II) blood group - highest level of insulin and cortisol, low lactate levels; in subjects with B (III) blood group - maximal lactatdehydrogenase and minimal amylase activity, high piruvate and lactate blood levels; in subjects with AB (IV) blood group - highest level of glucose, low lactatdehydrogenase and amylase activity, lowest lactate and piruvate blood levels were revealed. Conclusion. The particularities of molecular processes might be associated with blood group and predispose to different health conditions. The features of the metabolic profile of patients with different blood groups are the rationale for individualization of personal standards for each person that might reasonably be considered in clinical practice.
