Dr. Dave Stutkus shared some slides (on twitter) recently based on a lecture at Nationwide Children’s. Since I see children everyday who are undergoing poorly-conceived allergy testing, I wanted to share some of them.
- Excluding foods from diet based on allergy testing without concurrent symptoms can lead to allergies rather than tolerance:
- Newer antihistamines are safer
- Most individuals with penicillin allergy are not truly penicillin allergic. Also, there is a low rate of cross-reactivity with most cephalosporins.
- Proper allergy testing relies on the basic understanding that sensitization is not equivalent to being allergic. In addition, allergy testing has a high rate of false positives; therefore, testing needs to be limited (avoid broad panels).
Also, link to AAP guidelines on breastfeeding & eczema and introduction of foods to minimize development of allergies: The Effects of Early Nutritional Interventions on the Development of Atopic Disease in Infants and Children: The Role of Maternal Dietary
Restriction, Breastfeeding, Hydrolyzed Formulas, and Timing of Introduction of Allergenic Complementary Foods
