Abstract

Objective: To evaluate a relationship between preeclampsia and prolidase enzyme activity.

Methods: A prospective cohort study of 41 pregnant women diagnosed with preeclampsia and 31 healthy pregnant women as control group was selected at Harran University Hospital Department of Obstetrics and Gynecology. The prolidase enzyme activity was analyzed in maternal and umbilical cord plasma, amniotic fluid and placental and umbilical cord tissues by Chinard method in addition to maternal serum levels of lactate dehydrogenase (LDH), serum glutamate pyruvate transaminase (SGPT) and serum glutamate oxaloacetate transaminase (SGOT).

Results: A significant relationship was found between plasma prolidase activity (635 ± 83 U/L) (p = 0.007), umbilical cord plasma prolidase activity (610 ± 90 U/L) (p = 0.013), amniotic fluid prolidase activity (558 ± 100 U/L) (p = 0.001), umbilical cord tissue prolidase activity (4248 ± 1675 U/gr protein) (p = 0.013) and placental tissue prolidase activity (2116 ± 601 U/gr protein) (p = 0.001) in preeclamptic group when compared to healthy pregnant women.

Conclusion: There is a strong correlation between prolidase enzyme activity and preeclampsia. Prolidase enzyme activity may play a role in preeclampsia.

Keywords: Endothelial dysfunction; preeclampsia; pregnancy; prolidase enzyme activity; tissue and plasma.
