The pathogenesis of diabetic foot disease is multifactorial and encompasses microvascular and macrovascular pathologies. Abnormal blood rheology may also play a part in its development. Using a cell flow analyser (CFA), we examined the association between erythrocyte deformability and diabetic foot disease. Erythrocytes from diabetic patients with no known microvascular complications (n = 11) and patients suffering from a diabetic foot ulcer (n = 11) were isolated and their average elongation ratio (ER) as well as the ER distribution curve were measured. Average ER was decreased in the diabetic foot patients compared with the patients with diabetes and no complications (164 007 versus 171 +/- 01; P = 0036). A significant rise in the percentage of minimally deformable red blood cells RBCs in diabetic foot patients compared with the patients with no complications was observed (3789% +/- 812% versus 3061% +/- 1017%; P = 0039) accompanied by a significant decrease in the percentage of highly deformable RBCs (1247% +/- 443% versus 1749% +/- 817% P = 0046). Reduced erythrocyte deformability may slow capillary flow in the microvasculature and prolong wound healing in diabetic foot patients. Conversely, it may be the low-grade inflammatory state imposed by diabetic foot disease that reduces erythrocyte deformability. Further study of the rheological changes associated with diabetic foot disease may enhance our understanding of its pathogenesis and aid in the study of novel therapeutic approaches.
