The HELLP syndrome (hemolysis, elevated liver enzymes and low platelets): Clinical characteristics and maternal–fetal outcome in 172 patients

Abstract Objectives To analyze the frequency of the different clinical presentations of the disease in women with HELLP syndrome and the most important factors that can predict a different maternal and fetal outcome. Study design This is a cross-sectional, consecutive, case-series study, the subjects being all patients with HELLP syndrome admitted to our Hospital within the last decade (1999–2009). Results The rate of maternal complications was 43.0% and perinatal mortality 14.1%. The severity of the syndrome, measured by The Mississippi Classification, influenced the rate of maternal complications but not fetal mortality: the rate of maternal complications among women in class 1 HELLP syndrome was 67.6%, compared to 49.3% in class 2 and 24.0% in class 3 HELLP syndrome, p Conclusions These results suggest the possibility of an increased complication rate when the onset of the syndrome appears after delivery and the necessity of having a high grade of suspicion in every case to diagnose the disease, even when the gestation and delivery were normal.
