Abstract:
Objective By studying clinical features, treatment and prognosis of eosinophilic gastroenteritis of infants resulted from milk protein allergy an, to improve the diagnosis and treatment level of eosinophilic gastroenteritis. Methods 24 cases of infants which diagnosed eosinophilic gastroenteritis were chosen from June of 2010 to January of 2014 in children’s Hospital of XX province and By retrospective analysis clinical manifestations, endoscopic features, histopathology, treatment and prognosis of the 24 cases. Results The 24 cases who were vomiting, paroxysmal crying, abdominal distension (100.00%), which accompanied by haematemesis 23 cases (95.83%), 1case (4.17%) hematochezia, 17cases (70.83%) eczema, 21 cases (87.50%) mild to moderate anemia, 1 cases (4.17%) severe anemia, 19 cases (79.17%) the increasing of peripheral blood eosinophil cells, 8 cases (33.33%)the increasing of IgE of the serum and 4 cases (16.67%) the test of antibody of the Helicobacter pylori in Serum was positive; 3 cases (12.50%) were milk protein allergy by the detecting of food allergen-speciifc IgE antibodies, the endoscopic characteristics were hyperemia, edema, erosion, ulcer of gastric and duodenal mucosa. Among them, 24 cases (100.00%) were gastritis, 5 cases (20.83%) duodenitis and 1 cases (4.17%) duodenal ulcer. The histopathology of the 24 cases revealed that there were gastric or duodenal eosinophils infiltration (> 20/HPF) and were all associated with mast cell infiltration; By antisecretory, protection of the gastrointestinal mucosa and the obviating of milk protein had a satisfactory treatment effect, 24 cases of children with oral general formula milk test conifrmed that the milk protein allergy, The 3 cases of the patients were reviewed by 8~12 weeks after gastroscope, and the mucosa of the duodenum was smooth, Eosinophils were/HPF<8, mast cells were/HPF<5. Conclusion There are no speciifc clinical and endoscopic manifestations in eosinophilic gastroenteritis of infants resulted from milk protein allergy, gastrointestinal mucosa eosinophil inifltration and simultaneously are accompanied by abnormal mast cell inifltration;Mucosal type without the use of corticosteroids, through milk protein avoidance treatment can achieve satisfactory results, But definite diagnosis must rely on biopsy and eosinophils, combined with avoidance stimulation test of milk protein can further confirmed, But the excitation test should be at least 10 days of observation of children, and carefully recorded symptoms, so as not to delay the missed diagnosis of CMPA.
