Hypoproteinemia in the second trimester among patients with preeclampsia prior to the onset of clinical symptoms.

OBJECTIVE

To find a risk factor for "uncomplicated" preeclampsia (PE) comparing blood biochemical parameters between women with uncomplicated PE and healthy pregnant women in each trimester of pregnancy.

METHODS

A retrospective study was performed on 83 cases of uncomplicated PE, selected from 434 patients with PE, disregarding subjects with other complications relevant to hypertension during pregnancy. The study was limited to women with PE occurring in the third trimester, and records of blood biochemical parameters were evaluated. Controls were recruited from 108 healthy volunteers with normal singleton pregnancies.

RESULTS

A significant decrease in total protein was observed in the uncomplicated PE group in the second trimester prior to the onset of clinical symptoms.

CONCLUSION

Hypoproteinemia during pregnancy may be a risk factor for this pathophysiology, and the maintenance of sufficient protein in early pregnancy could contribute to prophylaxis for women with uncomplicated PE.
