Abstract

Primary aldosteronism (PA) is a common secondary cause of hypertension. Literature regarding PA in pregnancy has demonstrated poor outcomes. Compare the management and outcomes of PA in pregnancy to both high and low-risk matched controls. This was a case-control trial conducted in a network of metropolitan hospitals in Sydney, Australia. PA women (positive salt suppression test) with singleton pregnancies delivered after 20 weeks' gestation were matched to women with high- and low-risk pregnancies. Management outcomes included pre-eclampsia prophylaxis and antihypertensive medications required prenatally, antenatally, and postnatally. Maternal outcomes included incidence of pre-eclampsia, gestational diabetes, hypokalemia, mode of delivery, and length of stay postpartum. Neonatal outcomes included gestation, birthweight, intensive care unit admission, and length of stay. Fifty-nine women with 60 pregnancies were included (20 PA, 20 high risk, and 20 low risk). The number of antihypertensive medications women with PA took prepregnancy was similar to the high-risk group. A similar proportion of women in the PA and high-risk groups were prescribed pre-eclampsia prophylaxis and developed pre-eclampsia. Even after adjustment for several factors, PA was not independently associated with pre-eclampsia development. Women with PA had higher antihypertensive requirements and a longer stay in hospital postpartum than the high-risk group (both P = .02). There was no difference in neonatal adverse outcomes. Four women took epleronone during pregnancy without any adverse effects noted. Women with PA required more antihypertensives and had a longer postpartum length of stay than matched high-risk women, but similar rates of pre-eclampsia. There was no difference in the rate of neonatal intensive care admissions or adverse outcomes for neonates.
