Maternal serum levels of asymmetric dimethylarginine in normal and preeclamptic pregnancies

The study aims to investigate maternal serum levels of asymmetric dimethylarginine (ADMA) in pree- clampsia. Serum samples were collected from 57 women with preeclamptic pregnancies and 30 women with normal pregnancies during the third trimester. ADMA levels were measured with the ELISA method. ADMA levels in preeclamptic pregnancies were significantly higher when compared with normal pregnan- cies (2.35 ± 3.20 nmol/l versus 0.35 ± 0.10 nmol/l; p < .05). ADMA levels show a significant positive correl- ation with systolic and diastolic pressure, urea, and creatinine but a negative correlation with proteinuria. ADMA levels have a significant strong correlation with PE. ADMA levels are significantly higher in pree- clamptic pregnancy compared with normal pregnancy.
