Key clinical point: Antibiotic use early in life, especially within one year of age, disrupts the gut microbiome and increases the risk for atopic dermatitis (AD) at 5 years of age.
Major finding: Children who received antibiotics during the first year of life vs later were significantly more likely to develop AD at 5 years of age (adjusted odds ratio [aOR] 1.81; P < .001), with an increased number of antibiotic courses leading to a dose-response-like increased risk for AD (1 course: aOR 1.67; P = .0044; ≥ 2 courses: aOR 2.16; P = .0030).
Study details: This study analyzed the clinical data for AD diagnosis at age 5 years of 2484 children from the prospective, general population CHILD birth cohort, which enrolled pregnant women and infants with no congenital abnormalities born at ≥ 34 weeks of gestation.
Disclosures: The CHILD Study is funded by the Canadian Institutes of Health Research, the Allergy, Genes, and Environment Network of Centres of Excellence, Debbie and Don Morrison, and others. The authors declared no conflicts of interest.
