15 Question: Were the results biased against improvement because of: Infrequent use (3x/wk SLIT) Total load effect: 5 active/2 placebo had concomitant pollen sensitization ©2008 Allergychoices, Inc.

16 Questions for the future… SLIT for AD in adult patients? SLIT for AD with other inhalant allergens? SLIT for AD with food allergens? SLIT for AD with inhalant and food allergens? SLIT for other skin diseases?: urticaria from inhalants and/or foods? Contact dermatitis? ©2008 Allergychoices, Inc. All Rights Reserved.
