Elevated plasma endothelin in patients with diabetes mellitus

Elevated plasma endothelin in patients with diabetes mellitus 125 33 33 5 5 K. Takahashi M. A. Ghatei H. -C. Lam D. J. O'Halloran S. R. Bloom Department of Medicine, Royal Postgraduate Medical School Hammersmith Hospital London UK Summary Plasma concentrations of endothelin, a vasoconstrictor peptide released from vascular endothelial cells, have been measured by radioimmunoassay in 100 patients with diabetes mellitus and 19 healthy subjects. The plasma immunoreactive-endothelin concentrations were found to be greatly raised in the patients with diabetes (1,880±120 fmol/l, mean±SEM) compared with the healthy subjects (540±50 fmol/l, p <0.005). The elevation of immunoreactive-endothelin could not be explained by secondary changes in blood pressure or renal disease and did not correlate with the presence of diabetic retinopathy, duration of diabetes mellitus, fasting blood glucose or serum fructosamine. Fast protein liquid chromatographic analysis of the diabetic plasma immunoreactive-endothelin showed three forms, one in a very big molecular weight position, one intermediate and one in the position of endothelin-1 itself. No material appeared in the positions of endothelin-2 and 3. Chromatographic analysis of normal plasma showed only the big molecular weight peak while material in the endothelin-1,2 or 3 positions was below detection. The elevation of endothelin in diabetic patients may be a marker of, and further exacerbate, their vascular disease. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Diabetologia Springer Journals
