Longitudinal assessment of leukotriene B4, lipoxin A4, and resolvin D1 plasma levels in pregnant women with risk factors for preeclampsia.
    Clinical biochemistry, 2021, Volume: 98

    We carried out a longitudinal study to compare leukotriene B4 (LTB4), lipoxin A4 (LXA4), and resolvin D1 (RvD1) levels in pregnant women with risk factors for PE - who did (N = 11) or did not develop (N = 17) this clinical condition.. For both groups, plasma levels of the lipid mediators were measured using immunoassays at 12-19, 20-29, and 30-34 weeks of gestation.. LTB4 tended to be upregulated throughout gestation in women who developed PE. Moreover, this increase was significant at 30-34 weeks. Although LXA4 levels also tended to be higher in the PE group, this difference was not significant for the evaluated gestational periods. Pregnant women with PE had lower RvD1 levels and a low RvD1/LTB4 ratio at 30-34 weeks, compared to those in the normotensive pregnant women. Contrarily, RvD1 levels increased at weeks 12-19 in pregnant women who developed PE. Particularly, LXA4 and RvD1 levels were higher at 30-34 weeks than those at 20-29 weeks considering both groups of women. We observed an interaction between the gestational outcome and the gestational period in case of RvD1.. The imbalance among LTB4, LXA4, and RvD1 levels in these preeclamptic women is consistent with the excessive inflammation that underlies the pathogenesis of PE. Although our data highlight the potential for the use of these lipid mediators as clinical markers for PE development, future longitudinal studies must be carried out to confirm these findings.

Pre-eclampsia is associated with reduced resolvin D1 and maresin 1 to leukotriene B4 ratios in the plasma.

    Omega-3 and omega-6 fatty acids can be endogenously converted into mediators with pro-inflammatory (eg, leukotriene B4/LTB4) or anti-inflammatory/pro-resolving activities (eg, resolvin D1/RvD1 and maresin 1/MaR1). Recent data indicate an imbalance of LTB4 and MaR1 levels in pre-eclampsia (PE), but the relative production of these mediators, including RvD1, and the role of these mediators in the disease pathogenesis remain unclear. Therefore, this study aimed to investigate the plasma levels of LTB4, RvD1, and MaR1 in pregnant women with or without PE and non-pregnant controls and their association with clinical/laboratory parameters of PE women.. LTB4, RvD1, and MaR1 plasma levels were measured by competitive enzyme immunoassay in 19 non-pregnant, 20 normotensive pregnant, and 21 PE women.. Plasma concentrations of LTB4 were higher and RvD1 were lower in PE women than in normotensive pregnant women, who presented higher levels of LTB4 and similar levels of RvD1 to non-pregnant women. MaR1 levels did not differ among the groups. Pre-eclampsia women had decreased RvD1/LTB4 and MaR1/LTB4 ratios. Considering only the PE group, positive correlations were observed among all the mediators tested, between LTB4 and white blood cell count and between RvD1 and creatinine levels. However, all lipid mediators correlated negatively with body mass index before pregnancy. LTB4 also correlated negatively with maternal age.. Our findings suggest that the PE state results in systemic overproduction of LTB4 in relation to RvD1 and MaR1, and that these lipid mediators may be involved with the disease pathogenesis.
