Résumé
Ingestion of prebiotics during pregnancy and lactation may have immunomodulatory benefits for the developing fetal and infant immune system and provide a potential dietary strategy to reduce the risk of allergic diseases. The aim of this trial was to determine whether maternal supplementation with dietary prebiotics reduces the risk of allergic outcomes in infants with hereditary risk. We undertook a double-blind, randomized controlled trial in which pregnant women were allocated to consume prebiotics (14.2g daily of galacto-oligosaccharides and fructo-oligosaccharides in ratio 9:1) or placebo (8.7g daily maltodextrin) powder from <21 weeks gestation until 6-months postnatal during lactation. Eligible women had infants with a first-degree relative with a history of medically diagnosed allergic disease. The primary outcome was infant medically diagnosed eczema by 1-year of age, and secondary outcomes included allergen sensitization, food allergy, and recurrent wheeze by 1-year of age. 652 women were randomized between June 2016 and November 2021 (n=329 prebiotics, n=323 placebo). There was no significant difference between groups in the percentage of infants with medically diagnosed eczema by 1-year of age (prebiotics 31.5% (103/327 infants) compared to placebo 32.6% (105/322 infants); adjusted relative risk 0.98 (95% CI 0.77, 1.23; p=0.84). Secondary outcomes and safety measures also did not significantly differ between groups. We found little evidence that maternal prebiotics supplementation during pregnancy and lactation reduces the risk of infant medically diagnosed eczema by 1-year of age in infants who are at hereditary risk of allergic disease.
