Soluble ICAM-1 and E-selectin levels correlate with clinical and biological aspects of severe ovarian hyperstimulation syndrome

Objective: To assess the potential involvement of the soluble endothelial cell-leukocyte adhesion molecules E-selectin and intercellular adhesion molecule-1 (ICAM-1) in the pathophysiology of capillary hyperpermeability in the ovarian hyperstimulation syndrome (OHSS). Design: Controlled clinical study. Setting: Women hospitalized for severe OHSS after ovulation induction for IVF at two tertiary medical centers. Patient(s): Eleven patients with severe OHSS undergoing IVF and 20 controls who had received a similar ovulation induction regimen and did not develop OHSS. Intervention(s): Serial serum samples were obtained from all patients with OHSS from admission until discharge. Ascitic fluid was obtained from all patients by therapeutic paracentesis. Serum was obtained from all controls 4-8 days after ET. Main Outcome Measure(s): Samples were assayed for soluble E-selectin and soluble ICAM-1 by using enzyme-linked immunosorbent assay and results were correlated with clinical and biological aspects of OHSS. Result(s): Compared with controls, patients with severe OHSS had higher levels of soluble ICAM-1 and lower levels of soluble E-selectin detected in serum and ascites. Serum levels of soluble ICAM-1 decreased, while soluble E-selectin levels increased along with clinical and biological improvement. Serum soluble ICAM-1 showed significant positive correlation and serum soluble E-selectin showed significant negative correlation with clinical and biological aspects of severe OHSS. Conclusion(s): Soluble ICAM-1 and soluble E-selectin seem to be involved in the pathophysiology of capillary hyperpermeability in severe OHSS. (C) 2001 by American Society for Reproductive Medicine.
