The results of investigation of 49 children suffering from chronic gastroduodenitis and atopic dermatitis are presented. All the child underwent serological blood analyses for Epsteine-Barr virus antibodies and fibrogastroduodenoscopy with antral and duodenal mucosal biopsy. Hystomorphological and immunohystochemical studies of mucosal biopsy specimens for Epsteine-Barr virus were carried out.
