DIAGNOSTIC TECHNIQUE FOR EBV-ASSOCIATED GASTRODUODENITIS IN CHILDREN

摘要

FIELD: medicine. ^ SUBSTANCE: biopsy materials of a mucous membrane of a gastric corpus and a duodenum are analysed for mast cell count per 100 cells of infiltrate. At detecting more than 3.5 mast cells per 100 infiltrate cells in the biopsy materials of the mucous membrane of the gastric corpus and more than 4.75 cells per 100 infiltrate cells in the biopsy materials of the mucous membrane of the descending duodenum, immunohistochemistry or PCR diagnostics are required. If detecting Epstein-Barr virus antigens or DNA in the biopsy materials of the gastric and duodenal mucosa, EBV associated gastroduodenitis is diagnosed. ^ EFFECT: use of the technique allows diagnosing EBV associated gastroduodenitis in children. ^ 2 ex
