Abstract

Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of controlled ovarian hyperstimulation (COH). Its pathogenesis is not clarified yet. In the recent years a number of studies focused on the vascular endothelial growth factor (VEGF) and antihtrombin III (AT III) indicators. VEGF is homodimeric, heparin-binding glycoprotein, stimulating vascular permeability. Antithrombin III is protease inhibitor of activated clotting factors. This study aimed at examining the VEGF-A165 and AT III indicators with two OHSS patients. Two methods were used for the determination of the indicators of VEGF-A165 and AT III: ELISA for VEGF and chromogenic assay for ATT III. Kits of R/D Systems and American Diagnostica Inc. were used to estimate VEGF and AT III indicators in serum and plasma. There were higher indicators of VEGF-A165 (180pg/ml) and reduction of AT III indicators (48%) in the patient with a severe form of OHSS than in the control group while these indicators were normal in the patient with a moderate form of OHSS. Our results confirmed some published data concerning the importance of VEGF and AT III in the genesis of OHSS. This study should include a larger group of patients in order tofollow-up statistically and authentically the variations of the indicators of both factors and their importance for OHSS.
