Prenatal antibiotic exposure increases the risk of infant atopic dermatitis: data from a Greek cohort.

The human microbiome is important due to the impact it has on host immunologic development and allergy-associated diseases. This study aimed to investigate the impact of prenatal exposure to antibiotics on the incidence of atopic dermatitis (AD) in children at 18 months of age. Mothers were interviewed at baseline, in the maternity ward and by phone questionnaire after 18 months.
