Efficacy of very-low-dose oral food challenge in children with severe hen egg allergy: A retrospective, single-center case series.
Background: To avoid complete elimination of hen eggs (HE) from diet, we introduced a very-low-dose (VLD) oral food challenge (OFC) in patients with severe HE allergy in 2019. Herein, we investigated the efficacy of VLD HE OFC for achieving the full dose OFC.
Methods: Patients with an overt allergic reaction to LD (1/32 HE [≤100 mg]) or less, egg white (EW) protein within 6 months were included. In the VLD group, patients not achieving full-dose OFC (1/2 HE: 1600 mg EW protein) within 2 years were excluded. We retrospectively compared the rate of passing a full-dose OFC between patients who underwent a LD OFC before 2019 (LD group) and those who underwent a VLD OFC (1/100 HE: 32 mg EW protein) after 2019 (VLD group). The period for passing the full-dose OFC was evaluated using Kaplan-Meier survival analysis.
Results: We enrolled 411 and 111 patients in the LD and VLD groups, respectively. The median age at OFC initiation was 2.2 [1.5-3.6] and 2.1 [1.4-3.2] years in the LD and VLD groups, respectively. EW- and ovomucoid-specific IgE levels were 38.3 (12.5-72.9) and 21.0 (8.3-46.2) kUA/L in the LD group and 49.8 [18.8-83.9] and 32.1 [15.6-67.8] kUA/L in the VLD group, respectively. Over 4 years, the LD and VLD groups passed the full-dose OFC at rates of 70 and 95%, respectively, with significant differences (log-rank test, P < 0.001).
Conclusions: VLD HE OFC may contribute to passing a full-dose OFC in patients with severe HE allergies.
期刊介绍：
Allergology International is the official journal of the Japanese Society of Allergology and publishes original papers dealing with the etiology, diagnosis and treatment of allergic and related diseases. Papers may include the study of methods of controlling allergic reactions, human and animal models of hypersensitivity and other aspects of basic and applied clinical allergy in its broadest sense.
The Journal aims to encourage the international exchange of results and encourages authors from all countries to submit papers in the following three categories: Original Articles, Review Articles, and Letters to the Editor.
