| Abstract: | Preeclampsia is one of the most common and severe pregnancy complications, which ethiology remains unclear. It is certain that endothelial dysfunction plays a key role in the development of preeclampsia. Homocysteine is an important independent cardiovascular risk factor, which might induce the endothelial dysfunction observed in preeclampsia. 26 pregnant women--14 with preeclampsia (group 1) and 12 healthy term pregnant controls (group 2) were enrolled in the study between December 2003 and August 2004. Six of the women in this group had a superimposed preeclampsia. The mean homocysteine level in the first group was 11,04 mol/l, while in the control group it was 6,24 micromol/l (p < 0.05). The women with a severe preeclampsia had a significantly higher serum homocysteine levels than those with mild form (F = 0.025). Seven of the patients (50%) gave birth before 34th weeks of gestation. The study finds a link between the serum homocysteine as an endothelial dysfunction marker and the development of preeclampsia and a relation between the severity of preeclampsia and the degree of the elevation of the serum homocysteine levels. |
