If one course of steroids is good…. Then multiple courses must be even better Practice in the UK 1997
A survey of practice was carried out in the UK in 1997 98% of responding units prescribe multiple courses of antenatal steroids Brocklehurst P, Gates S, McKenzie-McHarg K, Alfirevic Z, Chamberlain GVP. Are we prescribing multiple courses of antenatal corticosteroids? A survey of practice in the UK. British Journal of Obstetrics and Gynaecology 1999; 106; 977-979. MULTIPLE COURSES OF ANTENATAL STEROIDS - BENEFIT OR HARM? • Multiple courses were not shown to confer additional benefits. L. M. Smith et al, J Matern Fetal Med 9 (2):131-135, 2000. • Multiple courses of antenatal betamethasone are associated with increased risks of perinatal infectious morbidity and neonatal death. S. T.

Is a single course safe? • 30-31 years follow up of Auckland randomised controlled trial of antenatal betamethasone – 1218 babies born • 75 g oral glucose tolerance test • Participants exposed to betamethasone had significantly higher plasma insulin concentrations at 30 min (60.5 vs 52.0 mIU/L) and lower glucose concentrations at 120 min (4.8 vs 5.1 mmol/L) • "Our findings of changes in the glucose-insulin axis provide experimental evidence to lend support to the glucocorticoid hypothesis for the fetal origins of adult disease" Dalziel SR et al: BMJ. 2005 Sep 24;331(7518) : Lancet. 2005 May 28-Jun 3;365(9474):1856-62 J Clin Endocrinol Metab October 2012 97:3457-9
Reynolds RM and Seckl JR The long-term effects of exogenous glucocorticoid exposure in late pregnancy for these children are unknown. data in a nonhuman primate model suggest dose-associated programming of cardiometabolic parameters the lowest dose of glucocorticoid possible should be used to minimize long-term adverse effects Kelly et al, Pediatrics 2012 128:1283-90 • Glucocorticoid exposure is associated with a localized increase in aortic arch stiffness, similar in magnitude to turn born individuals a decade older. The change in stiffness does not relate to changes in glucose metabolism that were also evident in this cohort Long, BN et al, Am J Obstet Gynecol 2013;208:217.e1-8 • This is the first demonstration that synthetic glucocorticoid doses in the clinical range have multigenerational effects on hypothalamo-pituitary-adrenal activity in precocial species, indicating the need for the study of long-term effects of fetal synthetic glucocorticoid exposure Outcome at 5 years of age • 1719 subjects; 871 given steroids • No benefits of multiple courses found • Odds ratio of neurosensory disability in babies born at term following multiple courses = 3.7 (1.57-8.75), P=0.005 Asztalos et al, JAMA Pediatr. 2013;167(12):1102-1110

BMJ. 2005 Sep 24;331(7518):645-6. • A single course of steroids reduces neonatal mortality in babies born before 34 weeks and this perhaps justifies the small risk of long-term side-effects. However, no such substantial benefit has been shown after this gestation. Delaying delivery until 39 weeks, unless necessary, would seem a more prudent option than giving steroids whose long-term safety, even as a single course, remains questionable. rapid response 9th October 2005 • Treatment group 26/467 (5.6%) admitted to SCBU for any reason • Controls 32/475 (6.7%) • Relative risk for neonatal admission following steroids of 0.82 (95% confidence interval 0.5 – 1.37) Stutchfield reply BMJ 14 December 2005 • The study was not powered or designed to show a difference in the total admission rate, merely the difference in the numbers admitted with respiratory distress. • If a larger study was designed and adequately powered to show an overall difference in all admissions, we are confident that a reduction would be seen as a direct result of fewer admitted with respiratory distress. Stutchfield trial follow-up • Lower rate of respiratory morbidity in steroid treated vs controls at age 8-15 years – 2% vs 9% • No difference in hospital admissions or • Low academic achievement significantly more common after steroids – 17.7% vs 8.5% (p=0.01) Stutchfield PR et al Arch Dis Child Fetal Neonatal Ed. May 2013; 98(3): F195–F200 Aiken et al 2014 • "a lack of effect of glucocorticoids on cognitive function following birth at term cannot safely be inferred by the apparent absence of an adverse effect in the context of preterm birth" • "exposing the fetus or neonate to potent synthetic may cause an early switch to differentiation and maturation in the developing brain" • "It is plausible that this could result in adverse effects on long-term neurodevelopmental outcome" Aiken C et al, JAMA Pediatrics June 2014;168:507-509 Aiken et al 2014 • "The question facing obstetricians and neonatologists is whether this degree of reduction in short-term respiratory morbidity justifies the risk that glucocorticoids may have an adverse effect on cognitive function of the child in later life. Given the present evidence, we do not believe the risk is warranted" Babies born preterm

Alexander N et al J Clin Endocrinol Metab 2012;97: 3538–3544 A population-based, multifaceted strategy to implement antenatal corticosteroid treatment versus standard care for the reduction of neonatal mortality due to the preterm birth in low income and middle income countries: the ACT cluster randomised trial Lancet. 2015 Feb 14;385(9968):629-39 • October 2011 – March 2014 • Argentina, Guatemala, India, Kenya, Pakistan, and Zambia • 51 Intervention clusters with 47,394 livebirths • 50 Control clusters with 50,743 livebirths • Antenatal steroids: 45% vs 10% Despite increased use of antenatal corticosteroids in low birthweight infants in the intervention groups, neonatal mortality did not decrease in this group, and increase in the population overall. For every thousand women exposed to this strategy, an excess of 3.5 neonatal deaths occurred, and the risk of maternal infection seems to have been increased "An unexpected and unfortunate finding was that the intervention resulted in an 11–12% relative increase in neonatal and perinatal mortality in the whole population." "This harmful effect was concentrated in infants at and above the 25th birthweight percentile, in whom the relative increase in mortality was 30%. Gestational age-based analysis showed a similar effect for term infants." How common is it for mothers given corticosteroids preterm to deliver at term? • Texas Women‟s Hospital1 – of 692 cases, 36% delivered >=34 weeks • National Maternity Hospital, Dublin2 – of 277 cases, 80% delivered >=34 weeks • Nova Scotia, Canada3 – Of 1,410 cases, 50% delivered >34 weeks 1.

Razaz N et al Obstet Gynecol 2015; 125(2):288-296 "for every suspected preterm delivery giving rise to an infant born before gestational week 34 there will be another one or two infants born at a later gestational age" "the benefits of the ACS administration, which they will most likely receive, are less obvious" Eriksson L et al Acta Obstet Gynecol Scand 2012;91:1415–1421 Antenatal corticosteroids: A time for more careful scrutiny of the indications? Vidaeff A, Belfort M and Steer P BJOG – In Press • Antenatal corticosteroid administration was a big step forward in improving the outcome in preterm birth • But you can have too much of a good thing – multiple courses should be avoided • Don‟t give it after 35 weeks • We need to improve our prediction of babies who will actually deliver preterm so as to avoid administration of steroids to babies who cannot benefit and may be harmed
