Core Tip

Core Tip: Systemic inflammatory response (SIR) markers including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), mean platelet volume (MPV), platelet distribution width (PDW) and red cell distribution width (RDW) have been widely investigated in preeclampsia (PE) and less analyzed in hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome. In this retrospective case-control study, SIR markers were compared among HELLP/PE patients and healthy gravidae. NLR, RDW, MPV and PDW were increased and PLR was decreased in HELLP syndrome. These parameters may become predictive and prognostic indicators and useful additions to the current diagnostic standard of HELLP syndrome, if confirmed by further more studies.
