Abstract

We report the case of a 10-year-old girl with a history of chronic diarrhea beginning at 10 months of age, accompanied by recurrent hypokalemia. More recently, she developed episodes of polyarthritis with prolonged fever. Laboratory investigations revealed markedly elevated inflammatory markers. Allergy testing for common allergens via IgE-mediated mechanisms yielded negative results; however, specific food items elicited high IgG-mediated responses. The patient was placed on an elimination diet excluding the identified intolerant foods, which led to significant improvement in gastrointestinal, joint, and nutritional symptoms. This case underscores the potential role of non-IgE-mediated food hypersensitivity in chronic inflammatory conditions.
