Although platelet-derived growth factor (PDGF) is thought to be a major mediator of atherosclerotic disease, the pathophysiology of diabetic vasculopathy, including atherosclerosis, is unclear. By means of an enzyme immunoassay that used a monoclonal antibody against human PDGF-B chain, PDGF-like immunoreactivity was determined in serum, platelet-poor plasma, and platelet lysate of 28 patients with non-insulin-dependent diabetes mellitus and 11 control subjects. Growth-promoting activity was also measured by tritiated thymidine incorporation into DNA of cultured human fibroblasts. The PDGF-like immunoreactivity in serum was correlated (r = 0.42; p less than 0.01) with that in platelet lysate prepared from a fixed volume of blood. Furthermore, a correlation (r = 0.70; p less than 0.001) was found between the PDGF-like immunoreactivity and the growth-promoting activity in platelet lysate but not in serum. There was no significant difference between patients with diabetes and control subjects with respect to the PDGF-like immunoreactivity in serum or in platelet lysate (38.2 +/- 2.2 vs 42.8 +/- 3.1 ng/ml or 49.1 +/- 2.4 vs 56.2 +/- 3.4 ng/mg protein; mean +/- SEM). In contrast, the serum growth-promoting activity was lower (p less than 0.05) in patients with diabetes than in control subjects (88.1% +/- 7.1% vs 117.4% +/- 6.9%) and there was a negative correlation (r = -0.39; p less than 0.05) between the serum growth-promoting activity and the fasting plasma glucose level. The growth-promoting activity in platelet lysate of patients with diabetes did not differ from that of the control subjects (59.9% +/- 11.6% vs 65.9% +/- 11.2%).(ABSTRACT TRUNCATED AT 250 WORDS)
