A systematic review and expert Delphi Consensus recommendation on the use of vaccines in patients receiving dupilumab: A position paper of the American College of Allergy, Asthma and Immunology.

BACKGROUND: Dupilumab is a monoclonal antibody that targets the interleukin (IL)-4 receptor alpha subunit, thus blocking the effects of IL-4 and IL-13, and has shown efficacy in treating various conditions including asthma, atopic dermatitis, eosinophilic esophagitis, and others. Because of its immune modulatory effects, clinical trials that studied dupilumab did not allow patients to receive live vaccines during the clinical trials because of an abundance of caution, and thus package inserts recommend that patients who are being treated with dupilumab should avoid live vaccines. Because dupilumab is now approved for use in patients from 6 months of age for the treatment of atopic dermatitis, this reported contraindication is now posing a clinical dilemma for patients and clinicians. OBJECTIVE: To perform a systematic review of literature on the safety and efficacy of vaccinations in patients who are receiving dupilumab and to provide expert guidance on the use of vaccines in patients who are receiving dupilumab. METHODS: A systematic review of the literature was performed, and an expert Delphi Panel was assembled. RESULTS: The available literature on patients who received vaccinations while using dupilumab overall suggests that live vaccines are safe and that the vaccine efficacy, in general, is not affected by dupilumab. The expert Delphi panel agreed that the use of vaccines in patients receiving dupilumab was likely safe and effective. CONCLUSION: Vaccines (including live vaccines) can be administered to patients receiving dupilumab in a shared decision-making capacity.

Food allergies on a college campus.

There are limited data on food allergies among college students. In this article, we review the most current available studies. These self-reported surveys and qualitative interviews reported overall poor avoidance of known allergens and low rates of carrying self-injectable epinephrine among students with food allergy. College students may exhibit risk-taking food behaviors due to a number of factors, including age-appropriate risk-taking predilection, strong social influences, and lack of experience in self-advocacy. Having to disclose an otherwise invisible condition repeatedly in a new environment may also lead to "disclosure fatigue," creating an additional barrier to self-advocacy. Common themes in the narrative include hypervigilance, stigma management, and concern about others' misunderstanding of food allergy. Although there is a paucity of data in this area, it is likely that having greater support at the institution level, along with support from peers and faculty, may help improve awareness, self-injectable epinephrine carriage, and allergen avoidance. This review also discusses strategies for preparedness at school, including specific steps to maximize safety.
