title: Neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, mean platelet volume, red cell distribution width and plateletcrit in preeclampsia.
abstract: OBJECTIVE
  Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), mean platelet volume (MPV), red cell distribution width (RDW) and plateletcrit (PCT) have all been recognized as systemic inflammatory response (SIR) markers. Our aim was to evaluate changes in NLR, PLR, RDW, MPV and PCT in preeclampsia and their use in predicting the severity of PE.
  
  
  METHODS
  This retrospective cohort study included 219 patients. Of them, 27 had mild PE, 82 had severe PE, and 110 were healthy, normotensive pregnant patients.
  
  
  RESULTS
  There were no significant differences in NLR between the groups (p=0.423). Both PLR and PCT were lower in the patients with severe PE than in the control group, and these differences showed a statistical significance (p=0.007 and p<0.001). On the other hand, both RDW and MPV were statistically higher in the patients with severe PE compared to the control group (p=0.011 and p<0.001). ROC analyzes were used to examine the ability of markers to predict those with severe PE from those with mild PE. Areas under the curve for NLR, PLR and RDW were not statistically significant (p=0.636, 0.104 and 0.36, respectively). For MPV and PCT, the values of area under the curve were 0.641 and 0.712, respectively, and the p values for these parameters statistically differed (p=0.028, p=0.001).
  
  
  CONCLUSIONS
  MPV or PCT may be clinical useful markers in the prediction of severe PE. Further, prospective multicenter studies are warranted to better reveal the association between SIR markers and PE.
