Abstract Background Low dose reactive cow's milk (CM) allergic children are at high risk of persistent CM allergy and a positive oral food challenge (OFC). The present study aimed to evaluate if the results of a very low dose (VL) OFC with these children contributes to better management of CM allergy. Methods We retrospectively reviewed subjects with CM allergy who underwent a VL OFC with 3 mL heated CM and had a previous allergic reaction to <25 mL heated CM in the 2 years before the OFC. Subjects who passed the OFC were defined as VL tolerant, and subjects who failed were defined as VL reactive. VL tolerant subjects increased the dose to 25 mL heated CM either during an OFC in our hospital or gradually at home. Results Of the 83 subjects (median age, 4.3 years; range, 1.0-12.9 years) who were included, 41 (49.4%) were VL tolerant, and 42 (51.6%) were VL reactive. Thirty-nine VL reactive subjects had skin and/or respiratory symptoms during the OFC. Most reactions could be treated with an antihistamine and/or a nebulized β2 agonist. The VL tolerant subjects consumed 3 mL heated CM or 10 g butter. Within the year following the OFC, 18 VL tolerant subjects (45.0%), but none of the VL reactive subjects, were able to consume 25 mL heated CM (p < 0.001). Conclusions A VL OFC allows the management of some low dose reactive CM allergic children to change from complete avoidance to partial intake of CM. © 2015 Japanese Society of Allergology. Source

Allergen avoidance is the standard treatment for managing food allergies. Complete avoidance is difficult, and accidental exposure often occurs. Immunotherapy is a significant focus for treating food allergies, and oral immunotherapy (OIT) appears to be particularly effective in inducing desensitization. The majority of patients who receive OIT show increased threshold doses of their food allergen. The efficacy of OIT is different among food antigen, and milk OIT is relatively difficult to achieve tolerance. OIT may induce mild to moderate symptoms during the therapy, widespread acceptance of OIT for long-term therapy is unclear. Recently, novel immunotherapies for food allergies, such as sublingual immunotherapy (SLIT), and epicutaneous immunotherapy (EPIT) and using an anti-IgE monoclonal antibody (omalizumab), have been assessed. In addition, a combination of OIT with omalizumab, which was found to increase the threshold doses of the offending foods without producing adverse reactions, may be effective and useful in the treatment of food allergies. These treatments have been used only in research settings; further studies in large numbers of patients are needed to demonstrate their long-term safety and benefits in clinical practice. © 2014, Allergy and Immunology Society of Thailand.
