Grading of reactions was defined by Bock et al.1 Grade 1 (mild) reactions did not require medications, whereas for any grade 2 (moderate) reaction, antihistamine was administered, and, in 2 cases, epinephrine was administered (by parent). Grade 3 (severe) reactions included 1 reaction during rush desensitization with severe rhinitis and moderate urticaria, treated with epinephrine (by physician); 1 reaction of generalized urticaria and severe rhinitis during the DBPCFC treated with antihistamines; 1 reaction of tongue swelling during the rush desensitization responding to oral antihistamines; and a reaction of severe abdominal pain during the home maintenance dosing, resolving with antihistamines. Reactions occurring at home were self-reported in diaries up to 24 to 28 weeks and were reported by phone or electronic mail throughout the study. Ten subjects have completed all 52 weeks of the study; reporting is complete for all subjects up to 36 weeks of the study.
