What's New in Eczema

What's new in Eczema

Parents often ask me for recommendations on special diets for their babies with “sensitive skin,” i.e. atopic dermatitis/eczema. Specifically, I’ve been asked whether they should consider hydrolyzed formula. Hydrolyzed means that the milk proteins have been broken down into smaller pieces. These formulas are advertised as “might be a good choice” for “skin rashes.”

However, a recent review (meta-analysis) of 37 clinical trials “found no consistent evidence to support a protective role for partially or extensively hydrolysed formula [for reducing risk of allergic or autoimmune disease].” In addition, researchers “found evidence of publication bias, methodological biases, and conflict of interest in those studies reporting allergic outcomes.”

In addition, the FDA’s conclusion summarized in Pediatrics was “there is little to very little credible evidence for a qualified health claim about W-PHF [whey protein partially hydrolyzed infant formula] and a reduced risk of AD [atopic dermatitis]”

Overall, it seems the guidelines that do recommend the consideration of hydrolyzed formula base this on “little evidence.” While parents often hope that changing the baby’s diet will improve matters, from a skin standpoint, it seems that special formulas are not the solution. If you or your child has eczema, please make an appointment for dermatology consultation at (626) 331-6411 to discuss your options.
