Abstract
Adverse reactions after food intake are commonly reported and a cause of concern and anxiety that can lead to a very strict diet. The severity of the reaction can vary depending on the type of food and mechanism, and it is not always easy to disentangle different hypersensitivity diagnoses, which sometimes can exist simultaneously. After a carefully taken medical history, hypersensitivity to food can often be ruled out or suspected. The most common type of allergic reaction is immunoglobulin E (IgE)-mediated food allergy (prevalence 5-10%). Symptoms vary from mild itching, stomach pain, and rash to severe anaphylaxis. The definition of IgE-mediated food allergy is allergic symptoms combined with specific IgE-antibodies, and therefore only IgE-antibodies to suspected allergens should be analyzed. Nowadays, methods of molecular allergology can help with the diagnostic process. The most common allergens are milk and egg in infants, peanut and tree nuts in children, and fish and shellfish in adults. In young children, milk/egg allergy has a good chance to remit, making it important to follow up and reintroduce the food when possible. Other diseases triggered by food are non-IgE-mediated food allergy, for example, eosinophilic esophagitis, celiac disease, food protein-induced enterocolitis syndrome, and hypersensitivity to milk and biogenic amines. Some of the food hypersensitivities dominate in childhood, others are more common in adults. Interesting studies are ongoing regarding the possibilities of treating food hypersensitivity, such as through oral immunotherapy. The purpose of this review was to provide an overview of the most common types of food hypersensitivity reactions.

Abstract
Background: Eosinophilic esophagitis is a complex disease with an increasing prevalence. Multidisciplinary teams are often needed to manage this difficult-to-treat condition. Objective: To observe the clinical and histologic outcomes of patients with eosinophilic esophagitis after management in a multidisciplinary clinic. Methods: An observational, retrospective chart review was conducted to include all patients referred to the Walter Reed National Military Medical Center multidisciplinary eosinophilic esophagitis clinic between August 2012 and February 2021. Only patients who had at least one esophagogastroduodenoscopy before referral, one or more visits and endoscopy after multidisciplinary management, and documented clinical symptoms were included. Statistical analysis was performed by using McNemar and Wilcoxon tests. Results: A total of 103 patients were included in the study, with a mean age at diagnosis of 17.9 years. Management in the multidisciplinary clinic was associated with a reduction in solid-food dysphagia by 70.9%, poor growth by 70.8%, and emesis or regurgitation by 87.5%. We observed that 48.5% and 62.1% had histologic remission (<15 eosinophils/hpf) on the initial and any post-multidisciplinary endoscopy, respectively. Only seven patients (5.8%) with two or more visits and endoscopies did not achieve histologic remission. More than two-thirds of the patients (68.9%) required combination therapy to achieve remission. Conclusion: Although an observational study, these findings may suggest that the management of patients with eosinophilic esophagitis in a multidisciplinary clinic may improve the likelihood of clinical and histologic remission. Targeted management with a multidisciplinary approach may reduce overall morbidity and slow disease progression; however, more research is needed.
