Abstract
Objective: To determine whether circulating concentrations of defined cell adhesion molecules, which are thought to reflect endothelial expression, are increased in insulin-dependent diabetic women during pregnancy. Methods: Pregnant diabetic women demonstrating good glycemic control and without major complications before pregnancy were studied at 8–12 (n = 15), 18 (n = 15), 28 (n = 16), 32 (n = 16), and 36 (n = 16) weeks’ gestation. A subgroup of ten diabetic women was sampled longitudinally through all five gestational ages. The diabetic women were compared with healthy nondiabetic women sampled cross sectionally at 12 (n = 20), 28 (n = 19), and 36 (n = 19) weeks’ gestation. Nonpregnant diabetic (n = 22) and nonpregnant nondiabetic women (n = 28) also were studied. Plasma concentrations of the cell adhesion molecules E-selectin, intercellular adhesion molecule-1 (ICAM-1), and vascular endothelial cell adhesion molecule-1 (VCAM-1) were measured by enzyme-linked immunosorbent assay. Results: Significantly higher median (range) concentrations of E-selectin (63.0 [20.2–107.0] ng/mL) and ICAM-1 (281.5 [171.6–778.4] ng/mL) but not VCAM-1 (459.7 [301.0–909.7] ng/mL) were found in nonpregnant diabetic women compared with nonpregnant nondiabetic women (43.5 [18.1–93.2], 243.6 [174.4–329.2], and 476.0 [253.8–929.4] ng/mL, respectively). During pregnancy these significant differences between diabetic and control groups were lost. The median (range) concentration of E-selectin (50.0 [21.2–96.3] ng/mL) was significantly lower in pregnant compared with nonpregnant diabetic women. The plasma concentrations of E-selectin and ICAM-1 did not change significantly with gestation in either diabetic or nondiabetic pregnant groups. Vascular endothelial cell adhesion molecule-1 concentration changed significantly with gestation in the diabetic pregnant group only. Conclusion: Circulating concentrations of defined vascular cell adhesion molecules are not increased abnormally in diabetic women with good glycemic control during otherwise uncomplicated pregnancy.This publication has 8 references indexed in Scilit:
