Abstract

Atopic dermatitis (AD) is an inflammatory, pruritic, noncontagious, chronic relapsing skin disease. Skin barrierabnormalities, excessive T helper 2 activity, and immune dysregulation are held responsible. Androgens have a negative effect on theintegrity of the epidermal skin barrier, while estrogen has a positive effect. We aimed to investigate whether hormones make a differencebetween healthy children and children with AD during minipuberty.Materials and methods: A total of 96 infants (postnatal 4–13 weeks), 48 diagnosed with AD and 48 controls, were included. Each groupconsisted of 23 girls (47.9%) and 25 boys (52.1%). Anthropometric examinations and hormone measurements were compared.Results: The two groups, having similar age, sex, body mass index, and weight-for-length standard deviation scores, were compared.Serum free thyroxine (FT4) levels were found to be lower and insulin-like growth factor binding protein-3 (IGFBP3) levels were foundto be higher in children with AD (p < 0.001 and p = 0.038, respectively). In girls with AD, estradiol, FT4, and insulin-like growth factor-1(IGF-1) levels were found to be lower, but thyroid-stimulating hormone (TSH) levels were found to be higher (p = 0.023, p < 0.001, p =0.038, and p = 0.034, respectively). In boys with AD, the FT4 level was found to be lower (p = 0.023). Serum FT4 and TSH levels werewithin normal reference ranges in all comparisons.Conclusion: Especially in girls with AD, decreased estradiol and IGF-1 levels were observed compared to the controls duringminipuberty. In the logistic regression model, decreased levels of serum estradiol, dehydroepiandrosterone sulfate, FT4, and IGF-1, andincreased levels of IGFBP3 were associated with an increased likelihood of exhibiting atopic dermatitis.
