Abstract

Objective To investigate the relationship between Lp-PLA2 levels in maternal serum and placenta and hypertensive disorders of pregnancy. Methods The levels of Lp-PLA2 in serum and placenta of 60 patients with hypertensive disorders of pregnancy (19 cases of gestational hypertension, 25 cases of mild preeclampsia, and 16 cases of severe preeclampsia) and 20 normal pregnant women (control group) were measured by enzyme-linked immunosorbent assay and immunohistochemistry. The relationship between levels of Lp-PLA2 and hypertensive disorders of pregnancy was analyzed. Results 1) The expression level of Lp-PLA2 in placenta of patients with hypertensive disorders of pregnancy was significantly higher than that of the control group (P<0.05), so was the expression level of Lp-PLA2 in the mild preeclampsia group (P<0.05). The level in the severe preeclampsia group was significantly higher than that of the mild preeclampsia group (P<0.05). 2) The level of maternal serum Lp-PLA2 was significantly higher than that of the control group(P<0.05). With the aggravation of the disease, the level of Lp-PLA2 increased gradually. There was significant difference between the two groups (all P<0.05). 3) There was a positive correlation between the levels of Lp-PLA2 in serum and in placenta of patients with hypertensive disorders of pregnancy (r=0.435, P< 0.05). Conclusions The increase of Lp-PLA2 levels may be related to the occurrence of hypertensive disorders of pregnancy. The change of Lp-PLA2 levels in maternal serum may be used as a monitoring indicator of the disease.
