[Changes in mean erythrocyte volume and 2,3-diphosphoglycerate in two groups of diabetic subjects]

Mean corpuscular volume and Red Blood Cell 2-3, diphosphoglycerate in insulin dependent diabetics and in non insulin dependent diabetics were evaluated. Only in insulin dependent diabetics an increased mean corpuscular volume was found while in non insulin dependent diabetics red blood cell 2-3, DPG level appears to be reduced. These findings were not correlated with the metabolic parameters neither they seemed to be dependent upon sex, age or vascular disease. The Authors suggest that the increase of mean corpuscular volume might be indicative of a tendency to macromegaloblastosis in insulin dependent diabetics; with regard to RBC 2-3, DPG level it seems to be extremely variable in dependence on oxygen request at the tissue level.
