Serum Levels of Asymmetric Dimethylarginine, Vascular Endothelial Growth Factor, and Nitric Oxide Metabolite Levels in Preeclampsia Patients

Background . Hypertensive disorder generally complicates 5–10 percent of all pregnancies. Angiogenic growth factors may be helpful for the diagnosis and prediction of preeclampsia. Therefore, in this study we attempted to determine the serum levels of asymmetric dimethylarginine (ADMA), vascular endothelial growth factor (VEGF), and nitric oxide (NO) metabolite (nitrite) in preeclampsia patients and compared the levels with those obtained from normal pregnant women. Methods . Ninety pregnant women (19–33 years old) in two groups of preeclampsia and normal were considered during 2012. The levels of ADMA, VEGF, and nitrite were measured in maternal serum samples using ELISA kits. Results . Significant increase of VEGF and nitrite levels was observed in preeclampsia patients when compared with other groups ( P < 0.05). The serum level of ADMA demonstrated a similar increased trend in preeclampsia patients; however, the increase was not statistically significant ( P = 0.08). Conclusion . The findings reveal that the elevation of serum levels of VEGF and nitrite and possibly ADMA may be involved in the pathogenesis of preeclampsia.
