BackgroundHemolysis, elevated liver enzymes and low platelets (HELLP) syndrome is a severe form of pre-eclampsia. Pre-eclampsia is a multi-system disease of pregnancy associated with an increase in blood pressure and increased perinatal and maternal morbidity and mortality. Eighty per cent of women with HELLP syndrome present before term. There are suggestions from observational studies that steroid treatment in HELLP syndrome may improve disordered maternal hematological and biochemical features and perhaps perinatal mortality and morbidity.ObjectivesTo summarise the evidence on the effects of corticosteroids on maternal and neonatal mortality and morbidity in women with HELLP syndrome.Search StrategyWe searched the Cochrane Pregnancy and Childbirth Group trials register (October 2003). We scanned lists of references from review articles and primary studies.Selection CriteriaRandomised and quasi-randomised trials evaluating the effects of adjunctive corticosteroids in patients diagnosed with HELLP syndrome were sought.Data Collection And AnalysisThe two authors independently applied inclusion criteria, assessed trial quality and extracted relevant data.Main ResultsOf the five studies reviewed (n = 170), three were conducted antepartum and two postpartum. Four of the studies randomised participants to standard therapy or dexamethasone. One study compared dexamethasone with betamethasone. DEXAMETHASONE VERSUS CONTROL: There were no significant differences in the primary outcomes of maternal mortality and morbidity due to placental abruption, pulmonary oedema and liver hematoma or rupture. Of the secondary maternal outcomes, there was a tendency to a greater platelet count increase over 48 hours, statistically significantly less mean number of hospital stay days (weighted mean difference (WMD) -4.50, 95% confidence interval (CI) -7.13 to -1.87), mean interval (hours) to delivery (41 +/- 15) versus (15 +/- 4.5) (p = 0.0068) in favour of women allocated to dexamethasone. There were no significant differences in perinatal mortality or morbidity due to respiratory distress syndrome, need for ventilatory support, intracerebral hemorrhage, necrotizing enterocolitis and a five minute Apgar less than seven. The mean birthweight was significantly greater in the group allocated to dexamethasone (WMD 247.00, 95% CI 65.41 to 428.59). DEXAMETHASONE VERSUS BETAMETHASONE: There were no significant differences in all the maternal and perinatal mortality and in primary morbidity outcomes. Women randomised to dexamethasone fared significantly better for: oliguria, mean arterial pressure, mean increase in platelet count, mean increase in urinary output and liver enzyme elevations.Reviewer's ConclusionsThere is insufficient evidence to determine whether adjunctive steroid use in HELLP syndrome decreases maternal and perinatal mortality, major maternal and perinatal morbidity.
