EGFR and Bcl-2 in gastric mucosa of children infected with Helicobacter pylori.

Unlabelled: The aim of the study was to evaluate the expression of EGFR and Bcl-2 proteins as inhibitory markers of apoptosis in surface epithelial cells and gland cells of antral gastric mucosa in children infected with Helicobacter pylori according to the severity and activity of antral gastritis and to assess the correlation between the number of cells expressing EGFR and the number of cells expressing Bcl-2 in H. pylori infected children.

Materials And Methods: The study included 44 children: 68.

The EGFR expression in gastric mucosa of children infected with Helicobacter pylori.

Purpose: Epidermal growth factor receptor (EGFR) modulates balance between proliferation and apoptosis in gastric mucosa of the gastrointestinal tract. The aim of the study was to evaluate immunohistochemically the EGFR expression in epithelial and gland cells of antral mucosa in children infected with Helicobacter pylori (H. pylori).

Helicobacter pylori eradication as prevention against chronic peptic ulcer disease in children.

The changes caused by Helicobacter pylori are a slow, progressing inflammatory process developing from several to dozen years. H. pylori infection leads to an inflammatory response in the gastric mucosa with granulocyte infiltrates in an acute form of the inflammation, and lymphocytes, plasmatic, macrophages and eosinophils in a chronic form inducing the development of gastric and duodenal ulcers and gastric cancer in some patients.
