Comparison of the Kisspeptin levels in early onset preeclampsia and late-onset preeclampsia

Abstract

Objective Maternal Kisspeptin plays role in cell migration which is responsible for trophoblast invasion. We aimed to investigate the role of Kisspeptin as an invasion marker in the early-onset and late-onset preeclampsia cases. Study design In this case-control study, 125 patients were included: 20 patients with early-onset preeclampsia and 20 gestational-age-matched healthy controls; 45 patients with late-onset preeclampsia and 40 gestational-age-matched controls). Maternal plasma Kisspeptin concentration was measured and compared in groups regarding the presence of early-onset and late-onset preeclampsia. Results In the late-onset PE group, significantly higher maternal plasma Kisspeptin values were observed compared with the control group at > 34 weeks of gestation (68.7 +/- 93.4 pg/ml vs 68.5 +/- 57.9 pg/ml; p = 0.004). Before the 34th week of gestation, plasma Kisspeptin levels did not show a significant difference when patients with early-onset PE and gestational-age matched controls were compared (66.8 +/- 87.9 pg/ml vs 48.5 +/- 91.3 pg/ml; p = 0.56). Conclusion Plasma Kisspeptin levels were significantly higher in women with late-onset preeclampsia, while no significant difference was observed in early-onset preeclampsia when compared with healthy gestational age-matched controls. The role of Kisspeptin proteins is still not clearly defined in the pathogenesis of preeclampsia.
