Key clinical point: Maternal probiotic supplementation was effective in preventing atopic dermatitis (AD) in children regardless of their filaggrin ( FLG) gene mutation status.
Major finding: Heterozygous FLG mutations were observed in 7% of children. The risk for AD after maternal probiotic supplementation was similar between children who expressed a FLG mutation (risk ratio [RR] 0.6; 95% CI 0.1-4.1) and those having a wild-type FLG (RR 0.6; 95% CI 0.4-0.9).
Study details: This exploratory study included the data of 228 children from the Probiotic in the Prevention of Allergy among Children in Trondheim (ProPACT) study who did or did not have FLG mutations and whose mothers received probiotic or placebo milk from 36 weeks of gestation until 3 months post delivery while breastfeeding.
Disclosures: This study was funded by the Liaison Committee between the Central Norway Regional Health Authority and the Norwegian University of Science and Technology, and the Norwegian Research Council. The authors declared no conflicts of interest.
