An overview of current clinical practice and international oral immunotherapy guidelines: A focus on Spanish, European, and Canadian guidelines.

Oral immunotherapy (OIT) is a recent and evolving therapeutic option for the treatment of immunoglobulin E (IgE) mediated food allergies. Clinical practice guidelines are starting to emerge to establish the parameters of this new clinical offer. A comparative analysis reveals several areas of consensus, such as the need for an accurate diagnosis with immunoglobulin E testing and, if necessary, open food challenge before initiating therapy; a list of specific contraindications; the importance of performing OIT in an adequate setting with appropriate level of expertise; the possibility to use grocery products to perform OIT; and the need to adapt protocols to patient needs. Certain discrepancies among the guidelines also underscore various areas of uncertainty, which makes it important that decisions to pursue the treatment be reached by using a shared decision-making approach that involves patients and caregivers. Gaps of knowledge remain with regard to treatment of adolescents and adults, and optimal performance measures in practice. These guidelines are expected to evolve in the coming years as new scientific and experiential knowledge is gained.
