Ischemia-Modified Albumin and Antioxidant Capacity of Blood Serum in Normal Pregnancy and Preeclampsia.

A comparative study of oxidative stress markers (ischemia-modified albumin (IMA) and the blood serum antioxidant capacity) in normal pregnancy and preeclampsia was carried out. The IMA level and blood serum antioxidant capacity increased in the following order: healthy non-pregnant women→healthy pregnant women→patients with moderate preeclampsia→patients with severe preeclampsia (p<0.001). A significant positive correlation was revealed between blood serum antioxidant capacity and uric acid levels in all the examined groups. The results showed that oxidative stress in preeclampsia is more pronounced compared to normal pregnancy. The levels of IMA and the blood serum antioxidant capacity can be additional criteria for assessment of the severity of preeclampsia and predicting of its course.
