Randomized Trial of Peanut Consumption in Infants at Risk for Peanut Allergy

The prevalence of peanut allergy among children in Western countries has doubled in the past 10 years, and peanut allergy is becoming apparent in Africa and Asia. We evaluated strategies of peanut consumption and avoidance to determine which strategy is most effective in preventing the development of peanut allergy in infants at high risk for the allergy.

Vitamin D Replacement Can Help Winter-Related Atopic Dermatitis

Vitamin D Replacement Can Help Winter-Related Atopic Dermatitis David J. Amrol, MD Reviewing Camargo CA Jr et al., J Allergy Clin Immunol 2014 Oct 134:831 The study involved children with mild to moderate AD without optimal topical treatment.

Atopic dermatitis (AD) frequently flares during the winter. This may be in part due to decreased humidity and skin dryness, but some evidence points to a role for low vitamin D levels. In a study in northern Mongolia, 107 children (mean age, 9 years) with a history of AD that worsens in the winter were randomized to oral cholecalciferol (one drop of 1000 IU daily) or placebo for 1 month during the winter. Vitamin D levels were not checked, but in other studies of Mongolian children, 98% had vitamin D levels less than 20 ng/mL during the winter. At 1 month, the treatment group had significantly greater improvement in AD scores than the placebo group (29% vs. 16%).

Comment

It is unclear if these results will be reproducible in a U.S. population. Also, these children had mild to moderate AD, emollients were given but not prescribed for daily use, and topical steroids were discouraged. With optimal AD treatment, the effect of vitamin D replacement may not have been as great. Still, in children with winter flares of AD it may be worth checking a vitamin D level or, because there are few known downsides, just prescribing low-dose vitamin D supplementation for 1 month.
