Anaphylactic food reaction often involves gastrointestinal symptoms, such as vomiting and abdominal pain, but to date, there have been no publications documenting the association between food hypersensitivity and intussusception. Herein is reported the case of a 2-year-old boy with intussusception accompanied by anaphylactic food reaction. The patient without known allergies complained of severe abdominal pain following ingestion of salmon roe for the first time. Dyspnea, wheezing and generalized urticaria also developed. Subsequently, he had stools containing jelly-like blood with mucus. At hospital arrival, physical examination identified an abdominal mass in the right lower quadrant; imaging confirmed the diagnosis of colo-colic intussusception. This patient was successfully treated with enema and no pathological findings were identified via radiology. Laboratory results supported the presence of IgE-mediated allergy to salmon roe in the present patient. To our knowledge, this is the first report to describe the possible association between intussusception and a hypersensitive food reaction.

Recurrent intussusception is a management dilemma and have many causes. We report a 22-month old boy who presented multiple times for recurrent intussusception. At diagnostic work-up he was found to be suffering from non-IgE food allergy. The child did not develop further episodes of intussusception after removal of allergenic diet.

Food protein-induced allergic proctocolitis (FPIAP) is a condition characterized by inflammatory changes in the distal colon in response to one or more foreign food proteins because of immune-mediated reactions. FPIAP prevalence estimates range widely from 0.16% in healthy children and 64% in patients with blood in stools. In clinical practice, FPIAP is diagnosed when patients respond positively to the elimination of a suspected triggering food allergen. Nevertheless, significant proportions of infants get misdiagnosed with IgE mediated allergy and undergo unnecessary dietary changes. Diagnosis is based on clinical symptoms, a good response to an allergen-free diet and the recurrence of symptoms during the "allergy challenge test". Sometimes clinical features may be non-specific and the etiology of rectal bleeding in childhood may be heterogeneous. Therefore, it is crucial to exclude a variety of other possible causes of rectal bleeding in the pediatric age group, including infection, anal fissure, intestinal intussusception and, in infants, necrotizing enterocolitis and very early onset inflammatory bowel disease. The diagnostic workup includes in those cases invasive procedures such as sigmoidoscopy and colonoscopy with biopsies. The high prevalence of FPIAP contrasts with the lack of known information about the pathogenesis of this condition. For this reason and due to the absence of a review of the evidence, a literature review appears necessary to clarify some aspects of allergic colitis. The aim of the review is to fill this gap and to lay the foundations for a subsequent evidence-based approach to the condition.
