New evidence in food allergies treatment

Purpose of review: To acknowledge, the newly available treatments for food allergy described in the latest scientific literature, such as oral immunotherapy (OIT), biologics and the combination of them in managing patients with IgE-mediated food allergies. Recent findings: Recent studies suggest that OIT and biologics, alone or together, can have a role as disease-modifying treatments for food allergies. The FDA has recently approved omalizumab as a treatment for food allergy. Other biologics are currently under evaluation and further studies are needed to assess the efficacy and safety of these therapies. Summary: The allergology scenario is rapidly evolving, the recent introduction and approval of new therapeutic strategies such as biotechnological drugs and allergen immunotherapy is changing the therapeutic paradigm: we are witnessing a shift from a strategy based on avoiding the trigger and reversing an allergic reaction already in progress, to one that aims to modify the natural history of the disease by acting on the immunological mechanisms that determine it. This approach is consistent with the modern perspective of a personalized patient-tailored medicine. In this opinion review, we will provide a brief analysis of current and future therapeutic options for IgE-mediated food allergy, focusing on OIT, biologics and their combination.
