"What’s New in..."

A monthly column by Dr. Chiang


November 2014

What’s New in in Eczema (atopic dermatitis)

I see expectant mothers who have suffered with sensitive skin (ie, eczema / atopic dermatitis) their entire lives. I am often asked how to decrease the chance their child will have to go through the same hassles they have (using only products designed for sensitive skin, applying medications during flares, and breaking out when simply applying fragrance during a night out). The most recent analysis found the most effective way to reduce the risk of passing on sensitive skin was to breast feed the child for at least the first four months of life, thereby reducing the risk by up to 33%. While this isn’t complete protection, this does add to the numerous other proven benefits of breast feeding and makes breast feeding even more highly recommended. This benefit was seen even when breast feeding was supplemented with formula. It only applies to children at high risk for atopic dermatitis (ie, having a first-degree relative with it). If a supplemental formula is used, it seems to be helpful to use one based on a hydrolyzed formula rather than intact cow’s milk.

The analysis also looked at antigen avoidance, ie avoiding certain foods such as cow’s milk, eggs, peanuts, fish, and chocolate, as some mothers do during pregnancy. If done during pregnancy, there was no protective effect and there was a tendency toward preterm birth. If done while breastfeeding, large trials did not show any benefit. Only one small trial showed a non-significant reduction in eczema severity. Overall, antigen avoidance does not seem practically useful in reducing eczema risk.

I hope you found this month’s column useful. If you have eczema, I look forward to seeing you. Please make an appointment for a dermatology consultation at (626) 331-6411.
