Maternal prebiotics may reduce infant allergy linked to antibiotic use in labour: Aussie study

The WA researchers followed pregnant women at increased risk of having infants with allergic disease.

Maternal prebiotic supplementation reduces the risk of infant allergies associated with antibiotics given during labour, an Australian study suggests.

The randomised controlled trial, published in Allergy, followed 568 pregnant women at increased risk of having infants with allergic disease based on family history.

The women took either daily prebiotics galacto-oligosaccharides and fructo-oligosaccharides or a maltodextrin powder placebo from 18-20 weeks’ gestation until six months’ lactation.

Data on antibiotic use were collected monthly and categorised by antenatal — 18-20 weeks’ gestation up to birth — intrapartum, C-section and lactation.
