Allergy testing accurately identifies the food triggers in EoE.
False: Eosinophilic (ee-uh-sin-uh-fil-ik) esophagitis (EoE) is an allergic condition that causes inflammation of the esophagus. The esophagus is the tube that sends food from the throat to the stomach.
Research suggests that the leading cause of EoE is an allergy or a sensitivity to particular proteins found in foods. In fact, up to 50% of patients show evidence of IgE sensitization to multiple foods. Foods such as dairy products, egg, soy and wheat are main causes of EoE. If you are diagnosed with specific food allergies after prick skin testing and patch testing, your doctor may remove specific foods from your diet. In some individuals this helps control their EoE.
However, the results of allergy testing alone do not always accurately identify the food triggers in EoE. Skin prick testing predicted 13% of causative foods in adults and children and combination prick and patch testing predicted 44% of causative foods in children. Food patch testing has not been standardized or validated in EoE. However, positive food patch tests do occur in 30 to 95% of children and adults with EoE.
