Abstract

We determined circulatory polymorphonuclear leukocytes (PMN) functions of superoxide anion production, adhesion and aggregation in 38 type 2 diabetic patients with and without diabetic triopathy. Tumor necrosis factor (TNF)-alpha-stimulated superoxide production and N-formyl-methionyl-leucyl-phenylalanine (FMLP)-stimulated aggregation in diabetic patients with triopathy were significantly greater than those in diabetics without triopathy. The more diabetic complications existed, the more TNF-alpha-stimulated superoxide was produced by PMN. These results suggest that the activated PMN contributes to a progression of diabetic triopathy in type 2 diabetic patients.
