Abstract
OBJECTIVE To evaluate the effects of a 14-day intensive insulin therapy and short-term improvement of glycemic control on serum levels of soluble forms of adhesion molecules, i.e., intercellular adhesion molecule-1 (sICAM-1), vascular cell adhesion molecule-1 (sVCAM-1), and E-selectin (sE-selectin) in NIDDM patients with poor glycemic control.
RESEARCH DESIGN AND METHODS A total of 16 NIDDM patients were compared with 23 healthy subjects (control group) and investigated before and after intensive insulin treatment.
RESULTS On day 0, sE-selectin and sVCAM-1 levels were significantly higher in NIDDM patients than in nondiabetic control subjects (median 87, range 63–115; median 544, range 408–797 vs. 58, 43–80; 443, 395–573 ng/ml, respectively) (P < 0.008 in both cases). On day 15, the fall in sE-selectin levels was significant (P < 0.0001) and at a lesser extent in sVCAM-1 levels (64, 48–85; 506, 417–678 ng/ml, respectively); these levels reached values that no longer differed from those of control subjects (P = 0.23 and 0.15, respectively). Moreover, the fall in sE-selectin was positively associated with the change in LDL cholesterol and the improvement of glycemia.
CONCLUSIONS In poorly controlled NIDDM patients, sE-selectin levels are increased and significantly fall to normal after short-term improvement of glycemic control. This suggests that assaying sE-selectin makes it possible to detect endothelium activation and to follow its reversal with euglycemia.
