A cow’s milk and soy protein-free diet was implemented with the help of a dietician. Within 2–4 weeks of commencing AAF, her irritability and aversive feeding behaviors settled, the diarrhea resolved, and her weight gain gradually improved over the following months. The cause of the diarrhea was not clear in this case but may have been related to an underlying food allergy. Duodenal biopsies were normal, which ruled out celiac disease or other enteropathy. A repeat gastroscopy CP-868596 price at 26 months of age found no abnormalities in esophagus, stomach and duodenum (esophageal mucosal eosinophil count 0/HPF). Following the gastroscopy, cow’s milk was reintroduced and a further gastroscopy

performed while she remained on a soy-free diet.

At that stage, the patient had regained weight to the 3rd weight-for-age percentile. A subsequent gastroscopy at 3 years after introduction of soy was also normal, including normal esophageal histology. At age 5 years the patient had no further clinical evidence of EoE while eating an unrestricted buy Erlotinib diet. Learning points: EoE in infancy may be part of the extended spectrum of cow’s milk protein allergy. Infants with EoE typically present with unsettled behavior, feeding aversion, frequent regurgitation and/or poor weight gain. The differential diagnosis of gastrointestinal cow’s milk allergy in infancy includes celiac disease, which in this case was excluded on duodenal histology (while on a wheat-containing diet). In infancy, treatment of EoE commonly relies on an amino acid-based formula while strictly avoiding cow’s milk and soy protein. The prognosis in this age group may be better than for older children and adults as infantile EoE can resolve after the development of immunological tolerance to cow’s milk protein. Case study 2 An 8-year-old

boy presented with a 12-month history of recurrent abdominal pain, odynophagia, lethargy and occasional regurgitation/vomiting. There was no history of food bolus impaction, change in bowel habits or loss of weight. His mother had a history of allergic rhinitis, and his father had been recently diagnosed as suffering from celiac disease. A gastroscopy was performed and revealed evidence of longitudinal furrowing of the esophageal mucosa. Esophageal MCE histology showed increased intraepithelial eosinophils (52/HPF in the upper, 46/HPF in the middle and 62/HPF in the lower esophagus) and basal cell proliferation of greater than 50% of the total epithelial thickness. Biopsies from stomach and duodenum were normal. Initial management by the treating gastroenterologist involved empirical dietary cow’s milk elimination. On review 3 months later, the patient reported a significant improvement in abdominal pain and reflux symptoms. A follow-up gastroscopy was performed 12 months later. Despite symptomatic improvement, esophageal biopsies revealed persistent eosinophilic infiltration with 92 eosinophils/HPF in the upper and 145/HPF in the lower esophagus.
