One Child's Food Fight: A Case Study of Oral Immunotherapy Treatment for Food Allergies

The prevalence of food allergy has risen dramatically in the last two decades. Primary care providers encounter food-allergic children on a daily basis. Although the standard of care has traditionally been strict avoidance of the allergen and advisement to carry an epinephrine autoinjector in case of an accidental exposure resulting in a severe reaction, food allergy research has progressed in the past decade concerning various immunotherapies that may provide an alternate treatment strategy. Oral immunotherapy (OIT), performed under the supervision of an allergist, is the most widely studied of these therapies. In the past, OIT has been available in the realm of clinical trials, but it is now being offered by a small but increasing number of allergists in private practice throughout the United States. Pediatric primary care clinicians should be aware of both the risks and possible benefits of this treatment, because they are likely to encounter patients who may inquire about OIT in their practices. In this case report, use of OIT will be reviewed in the treatment of a food-allergic child.
