Maternal and fetal parameters including umbilical artery PI and fibrinogen/CRP ratio as predictive factors of perinatal outcome in women with HELLP syndrome.

INTRODUCTION

HELLP syndrome appears in approximately 0.2-1% of all pregnancies and is associated with in- creased maternal and fetal mortality and morbidity. It is diagnosed in cases when all three of the following criteria are present: (1) microangiopathic hemolytic anemia with abnormal blood smear low serum haptoglobin and elevated LDH levels; (2) elevated ASPATand ALAT (levels of both enzymes more than twice the upper limit of normal values), or bilirubin more than 1.2 mg/dl; 3) platelet count below 150x1009 L(-1). The etiopathogenesis of HELLP syndrome is associated with abnormal placentation in the first trimester production of cellular active substances, and pathological response of the maternal organism.

Objectives

The aim of the study was to establish maternal and fetal characteristics and perinatal outcome in HELLP syndrome. The examination protocol included comparison of maternal blood parameters, umbilical artery pulsatility index (UmbA PI) in relation to short-term neonatal outcomes.

MATERIAL AND

METHODS

Retrospective data analysis of patients hospitalized at the Perinatology and Gynecology Department, Polish Mother's Memorial Hospital Research Institute between 2009-2013, due to HELLP syndrome was conducted.

RESULTS

None of the investigated maternal or fetal parameters correlated with the neonatal outcome.

CONCLUSIONS

Our study demonstrated that maternal parameters do not influence the perinatal outcome in women with HELLP syndrome. Moreover UmbA PI and fibrinogen/CRP ratio do not correspond to neonatal parameters, either Thus, none of the examined features can be used as a prognostic factor of the neonatal outcome. Further studies with large sample size are necessary but the rarity of this complication limits the possibility of research.
