Introduction: The etiology/pathophysiology of preeclampsia remains an enigma. Maternal inflammation (humoral and cellular) is a key factor in the etiology of late-onset preeclampsia (L-PrE). Presepsin is split out from the phagocytes membranes after phagocytosis. It is known as a novel inflammation marker. To our knowledge, this is the first study in literature in English to investigate maternal blood concentrations of presepsin in preeclampsia and healthy pregnant women. Methods: We examined maternal plasma interleukin-6, presepsin and pentraxin-3 concentrations in pregnant women with (n = 44) and without L-PrE (n = 44). These three inflammatory markers concentrations measured using enzyme-linked immunosorbent assays were compared. Results: The mean maternal age and gestational age at sampling are similar in the both groups (p >= .05). Interleukin-6, presepsin and pentraxin-3 concentrations differed between the groups (p < .05). There was no difference between the three inflammatory markers concentrations in patients with mild (22 patients) and severe (22 patients) preeclampsia in L-PrE (p >= .05). A significant discriminative role of interleukin-6, presepsin and pentraxin-3 for presence of L-PrE, with cutoff values of 39.74 pg/mL, 309.88 mg/L and 34.96 ng/mL, respectively, were reported in a ROC curve analysis. When the patients with and without small for gestational age infants (12 patients and 76 patients, respectively) were compared, it was determined that there was no differences between the interleukin-6, but there were differences between the presepsin and pentraxin-3 concentrations (p = .016, p = .008, respectively). Conclusion: Lower concentrations of interleukin-6/presepsin and higher concentrations of pentraxin-3 were associated with the development of preeclampsia. Further investigations of inflammatory/immunity markers in pregnancy are required and may ultimately lead to novel therapeutic approaches to treat complications of pregnancy.
