1/8. Food protein-induced enterocolitis syndrome: clinical perspectives.Food Protein-Induced enterocolitis syndrome (FPIES) is a symptom complex of severe vomiting and diarrhea caused by non-IgE-mediated allergy to cow's milk and/or soy in infants. Symptoms typically begin in the first month of life in association with failure to thrive and may progress to acidemia and methemoglobinemia. Symptoms resolve after the causal protein (usually sensitivity to both cow's milk and soy) is removed from the diet. Symptoms recur approximately 2 hours after reintroduction of the protein along with a coincident elevation of the peripheral blood polymorphonuclear leukocyte count. The sensitivity is usually outgrown by 3 years of age. The purpose of this review is to delineate the characteristic clinical features, diagnosis and management of FPIES. Furthermore, infantile FPIES will be discussed in relation to clinical syndromes that share features with it ("atypical FPIES") and other food-allergic disorders affecting the gastrointestinal tract.- - - - - - - - - - ranking = 1keywords = enterocolitis (Clic here for more details about this article) |
2/8. Food protein-induced enterocolitis syndrome: report of one case.We report a 76-day old infant who got diarrhea within the first week of life. He was treated as acute gastroenterocolitis and kept on feeding with regular infant formula. Because the symptoms persisted, the feeding formula was shifted to soy-based formula then to the highly-hydrolyzed formula and got improvement. But severe bloody diarrhea, vomiting, dehydration and fever developed after feeding with regular infant formula again. Based on the history and clinical presentations, cow's milk allergy was suspected. He received total parenteral nutrition for 5 days then fed with highly-hydrolyzed formula with slowly increasing amount. Thereafter tests for total eosinophil counts, total serum IgE, milk specific IgE antibodies and milk extract skin prick test were all unremarkable. Under the impression of food protein-induced enterocolitis syndrome (FPIES), a double-blind placebo-controlled food challenge (DBPCFC) with infant formula was performed. Regular infant formula induced severe vomiting, diarrhea, fever, acidosis and elevation of absolute neutrophil counts (ANC) of peripheral blood by 27,640/mm3. Based on the laboratory findings and challenge results, the patient fit the diagnostic criteria of food protein-induced enterocolitis syndrome.- - - - - - - - - - ranking = 1.75keywords = enterocolitis (Clic here for more details about this article) |
3/8. Food protein-induced enterocolitis syndrome--not only due to cow's milk and soy.Over a of 7-year period, six patients (four males, two females aged 3-12 months) were diagnosed with food protein-induced enterocolitis syndrome (FPIES) triggered by foods other than cow's milk and soy: chicken in four, turkey in two, peas in one, and lentils in one (five patients reacted to more than one food type). All reactions developed within 2 h of ingestion of the allergenic food. To exclude other conditions with similar clinical symptoms, three infants underwent work-up for sepsis, one infant underwent work-up to exclude metabolic defects, and one underwent a barium enema to rule out intussusception. All were negative. Pediatricians should be aware that FPIES may be caused by foods other than cow's milk and soy, mainly chicken, turkey and foods from the legume family, and that it may present also in infants older than 6 months.- - - - - - - - - - ranking = 1.25keywords = enterocolitis (Clic here for more details about this article) |
4/8. Rice-induced enterocolitis in an infant: TH1/TH2 cellular hypersensitivity and absent IgE reactivity.BACKGROUND: Although food allergy is common in children, rice allergy is unusual in Western cultures. OBJECTIVE: To report a case of T-cell-mediated rice intolerance in an 11-month-old girl. methods: To evaluate the intolerance to rice in this patient, a graded rice food challenge was performed. To examine the immunologic reactivity to rice, in vitro lymphoproliferative responses and cytokine synthesis of rice-stimulated peripheral blood lymphocytes (PBLs) was performed. Subsequently, skin patch testing to rice and other foods was performed. RESULTS: Allergy skin prick test results were negative for rice and positive for egg, milk, and soy. Specific IgE antibodies to rice, egg, peanut, wheat, walnut, codfish, milk, soybean, corn, shrimp, scallops, and clams were undetectable. Results of a single-blind rice food challenge were positive, manifested by emesis that persisted for more than an hour and required intravenous hydration. in vitro lymphoproliferation by the patient's PBLs to rice stimulation was positive. In addition, cytokine synthesis of interferon-gamma, interleukin 10 (IL-10), tumor necrosis factor a, and IL-5 by the patient's rice-stimulated PBLs was elevated, indicating a TH1/TH2 cell response to rice. endoscopy revealed normal esophageal, gastric, and duodenal mucosa; a biopsy specimen revealed mild esophagitis. Duodenal explant T cells were initially established by stimulation with rice and IL-2. After a 2-day rest, the lymphocytes were restimulated with rice for 7 days and revealed increased interferon-gamma and IL-5 synthesis. Twenty billion colony forming units of lactobacillus GG were added to the patient's diet twice daily. After 6 weeks, rice rechallenge resulted in emesis within 1 hour. Results of patch testing were positive to rice, wheat, and barley but negative to soy, which the patient tolerated on food challenge. CONCLUSIONS: Although this patient did not demonstrate IgE antibody to rice, TH1/TH2 cell-mediated responses to rice were detected, and the patient experienced significant morbidity. Patch testing for gastrointestinal food allergies may be useful when the food specific IgE antibody is negative. Probiotic therapy in this patient did not ameliorate her sensitivity to rice, and food elimination remains the only reliable treatment for TH1/TH2-mediated food hypersensitivity.- - - - - - - - - - ranking = 1keywords = enterocolitis (Clic here for more details about this article) |
5/8. Food protein-induced enterocolitis syndrome: case presentations and management lessons.enterocolitis induced in infants by cow's milk and/or soy protein has been recognized for decades. Symptoms typically begin in the first month of life in association with failure to thrive and may progress to acidemia and shock. Symptoms resolve after the causal protein is removed from the diet but recur with a characteristic symptom pattern on re-exposure. Approximately 2 hours after reintroduction of the protein, vomiting ensues, followed by an elevation of the peripheral blood polymorphonuclear leukocyte count, diarrhea, and possibly lethargy and hypotension. The disorder is generally not associated with detectable food-specific IgE antibody. There are increasing reports of additional causal foods, prolonged clinical courses, and onset outside of early infancy, leading to description of a food protein-induced enterocolitis syndrome. The disorder poses numerous diagnostic and therapeutic challenges. The purpose of this report is to delineate the characteristic clinical features and review the possible pathophysiologic basis to frame a rational strategy toward management.- - - - - - - - - - ranking = 1.25keywords = enterocolitis (Clic here for more details about this article) |
6/8. Rice protein-induced enterocolitis syndrome.BACKGROUND AND AIMS: Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated allergic reaction, usually to cow's milk or soy protein. The aim is to present a series of infants with enterocolitis syndrome developed after rice ingestion. To our knowledge, the issue has only once been described in patients from europe. methods: Data on five patients were retrospectively analyzed. The patients presented with vomiting, diarrhea and dehydration; therefore, allergy was not considered as a diagnosis and the patients underwent broad diagnostic evaluation. Finally, an open food challenge was performed for suspicion of rice allergy. RESULTS: Detailed clinical and laboratory findings are presented. As all patients had symptoms which could have been indicative of a broad spectrum of diseases, a median of two hospitalizations was needed to establish the diagnosis. When the rice protein-induced enterocolitis syndrome is suspected all patients should undergo open food challenge test, as no other diagnostic procedure can confirm the diagnosis. CONCLUSION: This report shows that even hypoallergenic foods such as rice may cause FPIES and should be considered in the differential diagnosis of profuse vomiting and prostration in infants introduced to some kind of rice protein.- - - - - - - - - - ranking = 1.75keywords = enterocolitis (Clic here for more details about this article) |
7/8. tacrolimus-associated eosinophilic gastroenterocolitis in pediatric liver transplant recipients: role of potential food allergies in pathogenesis.tacrolimus is a macrolide agent that is now the primary immunosuppressant used in prevention of graft rejection in transplant recipients. It has been found to be superior to cyclosporine (CSA) for rescue therapy as well as for earlier weaning of steroids. Both tacrolimus and CSA share similar toxicity profiles; however, their gastrointestinal side effects have received little attention. We report three cases of eosinophilic colitis in liver transplant recipients, maintained on tacrolimus as immunosuppressive medication post-liver transplantation. These patients also had high serum immunoglobulin (Ig)E levels, eosinophilia and IgE-positive radioallergosorbent test for milk proteins. The colitis appeared to be mediated by food allergies. Each patient had symptomatic improvement following reduced immunosuppression and an appropriately restricted diet. We conclude that tacrolimus may play a role in the initiation of food allergies, leading to eosinophilic colitis. More studies are needed in a controlled setting to identify the prevalence of similar findings among other pediatric liver transplant recipients.- - - - - - - - - - ranking = 1keywords = enterocolitis (Clic here for more details about this article) |
8/8. Necrotizing enterocolitis as a result of cow's milk allergy?A three-day-old newborn developed necrotizing enterocolitis in absence of the usual precipitating factors. Colonic perforation necessitated surgical intervention. After recovery cow's milk allergy was diagnosed. Probably this food allergy was the cause of the development of the necrotizing enterocolitis.- - - - - - - - - - ranking = 1.5keywords = enterocolitis (Clic here for more details about this article) |
