Abstract
Two patients suffering from eosinophilic gastroenteritis (EG) were treated with sodium cromoglycate (SCG). Before treatment they showed enteric and cutaneous symptoms, such as abdominal pain, nausea, vomiting, diarrhoea and recurrent urticaria and angioedema. The histological findings were a notable amount of eosinophilic infiltration in the lamina propria and gastric glands, a villous shortening and thickening and weak eosinophilic inflammation in the duodenum. The patients were treated with 300 mg SCG, 4 times daily, for 4/5 months. During treatment, the clinical symptoms disappeared and at the end of treatment a reduced inflammation with an almost complete decrease of eosinophilic infiltration was observed. The results provide evidence of SCG efficacy in the treatment of EG and suggest its employment as an alternative to the steroids commonly used in EG.
