The content of matrix metalloproteinase-12 in pregnancy complicated by preeclampsia

Abstract

Relevance. Pre-eclampsia is the most difficult and important problem in obstetrics, it ranks third in the structure of maternal mortality. Until now, there is no single idea of the mechanisms of development of this pathological process. The study of the concentration of MMP-12 in pregnancy will determine its possible role in the development of pre-eclampsia. Aim. Сompare the dynamics of the concentration of matrix metalloproteinase-12 (MMP-12) in pregnancy complicated and not complicated by preeclampsia. Materials and methods. A prospective study of two groups of women: the main group is pregnant (n = 17) with preeclampsia (moderate (n = 11) and severe (n = 6)), the comparison group is women whose pregnancy was not complicated by preeclampsia (n = 83). The concentration of matrix metalloproteinase-12 was determined by the method of enzyme immunoassay in serum at 11-13, 22-24, 32-34 weeks of gestation. Results. In the group of pregnant women without preeclampsia, there was a sharp decrease in the concentration of MMP-12 from the I trimester to II (p = 0.0001), followed by a slight increase to the III trimester. In the group of pregnant women with preeclampsia, an increase in the concentration from the I trimester to II (p = 0.0001) was established. A significant difference in the concentration of MMP-12 between groups in the first trimester of pregnancy was shown (p = 0.0001). Conclusion. Thus, the results of the study indicate the role of MMP-12 in the initial stages of placentation.
