Aim: The aim was to explore the features of epithelial morphogenesis and reparation of gastric mucosa in chronic gastritis in patients with Marfan syndrome and Marfan -like states.
Materials and methods: A histological evaluation and immunohistochemical analysis of the expression of antibodies against α-actin smooth muscle (α-SMA), collagen type III and transforming growth factor β (TGFβ) in the gastric mucosa in 50 patients with hereditary disorders of connective tissue between the ages of 17 to 41 years were performed.
Results: In patients with Marfan syndrome and marfan-like states chronic gastritis was an unfavorable factor for the progression of the background atrophic and fibrotic processes in the gastric mucosa. It proved a key role disinhibited to TGFβ activity-dependent activation of fibrogenesis of subepithelial myofibroblasts (α-SMA +) with the development of a special morphogenetic variants of early chronic atrophic multifocal gastritis at a young age.
