    Abstract:
    AIM: To investigate vascular endothelial growth factor (VEGF) serum levels in severe preeclampsia (PE) and HELLP syndrome. PATIENTS AND METHODS: Serum concentrations of VEGF, progesterone, estradiol and estriol were measured in 16 patients with PE and 14 patients with HELLP syndrome and in 30 well-matched normotensive pregnant controls. Determination of VEGF was performed by a commercially available immunoassay (Quantikine(R), R&D Systeme, Wiesbaden), those of sex steroids by a radioimmunoassay (Fa. Biermann, Bad Nauheim). RESULTS: Serum VEGF levels were significantly higher in the study than in the control group (172.0 +/- 98.9 pg/ml versus 41.4 +/- 30.5 pg/ml, U-Test: p < 0.001). In patients with HELLP syndrome mean serum VEGF concentrations were increased when compared with healthy controls but serum levels were significantly lower than in patients with PE (109.2 +/- 68.5 pg/ml versus 219.0 +/- 72.9, U-Test: p < 0.05). We could demonstrate a positive correlation between VEGF and estradiol serum concentrations in the study and control patients (Spearman rang correlation: p < 0.05). CONCLUSIONS: It is concluded that patients suffering from PE or HELLP syndrome have either an increased placental expression of VEGF as a result of hypoxia or show an increased extraplacental production of this growth factor such as in maternal or fetal endothelial cells, macrophages or smooth muscle tissue.
