Maternal serum AMP-activated protein kinase levels in mild and severe preeclampsia

To investigate Phosphorylated adenosine monophosphate activated protein kinase (AMPK) levels in healthy pregnant women and pregnant women with preeclampsia (PE).

Twenty-eight women with mild-PE, 22 with severe-PE, and 30 normotensive controls were included in this cross-sectional study. The serum AMPK levels of these patients were analyzed. The patients were followed up to delivery.

No statistically significant difference was found between the groups for age, gravida, parity, and gestational age at the time the blood samples were obtained (p > .05). No significant difference between the group with mild-PE and the control group was found, while in the severe-PE group, serum AMPK levels were significantly higher relative to both the mild-PE and control groups (p < .001 and p < .001, respectively). No correlation was detected between serum AMPK levels and age, body mass index (BMI), and gestational age at the time the blood samples were collected. A negative correlation was found between AMPK levels and gestational week and birthweight at delivery, while a positive correlation was detected between systolic and diastolic blood pressures and AMPK levels.

Serum AMPK was higher in patients with severe-PE compared with healthy pregnant women and patients with PE without severe features so it might be a new biomarker for the prediction of disease and its severity.
