Abstract

AIM:

To determine antepartum and postpartum serum heme oxygenase-1 (HO-1) levels in pre-eclamptic (PE) and normotensive pregnant women and to investigate the relationship between HO-1 levels and severity of PE.

PATIENTS AND METHODS:

Ten normotensive women were compared to 9 women with mild PE and 12 women with severe PE. Serum HO-1 levels were measured at 30-34 gestational weeks and 12-14 weeks postpartum.

RESULTS:

The severe PE group had significantly higher serum HO-1 levels antepartum compared to the mild PE and normotensive groups (5.50 ± 1.54 vs. 3.04 ± 0.72 ng/ml, p=0.0003, and 5.50 ± 1.54 vs. 3.12 ± 1.57 ng/ml, p=0.002, respectively). Serum HO-1 levels decreased significantly postpartum in the normotensive group only (3.12 ± 1.57 vs. 2.00 ± 0.97 ng/ml, p=0.0005). In the severe PE group, HO-1 levels antepartum were positively correlated to mean blood pressure (r=+0.79, p=0.004).

CONCLUSION:

Severe PE is associated with elevated serum HO-1 levels both antepartum and postpartum, suggesting a key role of chronic oxidative stress in the pathogenesis of PE and the endothelial dysfunction of these patients later in their life.
