Newborns who go on to develop atopic dermatitis (AD) show higher transepidermal water loss (TEWL) and cord blood serum levels of CCL17/thymus- and activation-regulated chemokine (TARC) and interleukin (IL) 31.

"This study highlights the potential of cord serum/TARC and IL-31 levels as predictive markers for AD onset in infancy, in combination with cutaneous markers," the authors wrote. "Stratified interventions based on these variables, family history, FLG [filaggrin] variations, and other biomarkers could offer more targeted approaches to AD prevention and management, especially during the first year of life," they added.

The study was led by Angelo Massimiliano D'Erme, MD, PhD, of the Dermatology Unit, in the Department of Medical and Oncology, University of Pisa, Pisa, Italy, and was published online on September 11 in JAMA Dermatology.

The limitations included the observational design and small sample size, and it was a single-center study.
