• C-reactive protein;
  • D-Dimer;
  • Procalcitonin;
  • severe pre-eclampsia;
  • systemic inflammatory response syndrome (SIRS)


The aim of this study was to evaluate serum procalcitonin (PCT), C-reactive protein (CRP), and plasma D-Dimer levels in mild and severe pre-eclampsia.

Method of study

Serum PCT, CRP, and D-Dimer levels were analyzed in 64 cases with pre-eclampsia as the study group and 33 healthy pregnant women in the third trimester as the control group. Pre-eclamptic group consisted of mild (n = 31) and severe pre-eclamptic subgroup (= 33). Laboratory results were compared between the groups and diagnostic usefulness of these parameters were evaluated.


PCT, CRP, and D-Dimer levels were significantly higher in study group than the control group (= 0.001). PCT, CRP, and D-Dimer were significantly higher in the patients with severe pre-eclampsia than mild pre-eclampsia. There were significant positive correlations between these markers and mean arterial pressure (MAP). Logistic regression analysis using the control and pre-eclampsia group showed that higher PCT (OR, 15.68; 95%-CI, 3.15–78.10), CRP (OR, 14.29; 95%-CI, 3.08–66.34), and D-Dimer levels (OR, 4.97; 95%-CI, 1.22–20.29) were found to be risk factors significantly associated with pre-eclampsia.


This study results confirm that evidence of a possible exaggerated systemic inflammatory response in pre-eclampsia especially in severe pre-eclampsia.
