Gestasyonel diyabetes mellitus, obezite ve travayın fetal vasküler yapıya etkisinin araştırılması

Objective: To assess the expression of VEGF (vascular Endothelial Growth Factor) of umbilical vein intima in patiaents with GDM (Gestational Diabetes Mellitus), obese patients and patients who delivered normally and to determine the relationship between these findings and pregnancy outcome. To investigate the relationship between VEGF expression and maternal uterine artery, umbilical artery and fetal middle cerebral artery Doppler velocimetry.Method: 159 patients with singleton pregnancy who were between the 37-40th week of gestations included in the study. 30(%18,87) patients who cannot be found paraffin blocks in the Department of Pathology, 5(%3,14) patients who gave birth outside the hospital and 2 (%1,26) patients who received a diagnosis of preeclampsia were excluded from the study. The remaining 122 patients were divided into four groups: GDM group (13 patients), obesity group (13 patients), labor group (50 patients) and control group (46 patients). Before the delivery Doppler examination was performed to all patients. At the same time, maternal serum CRP (C-reactive protein) and lipid profile levels were measured. The umbilical cords after deliveries were sent to the Department of Pathology for immunohistochemistry examination.Results: The distribution of CRP values and VEGF score was significantly found among the groups (p=0,020 and p=0,0001, respectively). Levels of VEGF were significantly higher in the labor group compared with the control, obesity and GDM groups (p=0,0001). Obesity significantly decreases the values of VEGF (p=0,002). GDM also decreases the values of VEGF but its influence was not significantly found out. The increasing values of CRP doesn?t influence the VEGF score, in spite of this increasing of HDL levels (High Density Lipoprotein) significantly decreases the VEGF score (p=0,043). There was not significantly relationship between Doppler velocimetry and VEGF score.Conclusion: We think that the increasing value of VEGF is a protective fetal mechanism. So, we may reduce the incidence of unexplained fetal death and fetal malformations by reinforcement of VEGF in patients at risk groups.Key words: Gestational Diabetes Mellitus, obesity, VEGF, unexplained fetal death, fetal malformation
