title: [The enterochromaffin-serotonin system and Helicobacter infection in the mechanisms of the staged development of peptic ulcer].
abstract: Submitted in this article are scientific propositions and problems concerning the way ulcer disease (UD) of the gastroduodenal system (GDS) develops through its particular stages, and pathosanogenous role which the enterochromaffin-serotonin system (ECSS), a part of the diffusive neuroendocrine APUD-system of the organism, has in it, along with etiopathogenetic role Helicobacter infection plays in the gastroduodenal mucosa (M). Experience gained by the authors with prospective comprehensive evaluation and treatment of 310 patients with chronic gastroduodenitis (CGD), 198 UD GDS patients and 350 of those surgical patients who had undergone resection of the stomach for complicated UD GDS, indicates that all above pathological states share common etiopathogenetic, clinical, histomorphological and microbiological (Helicobacter infection) features, which facts suggest a common pathomorphogenesis of CGD, erosive GD, UD GDS and postgastroresectional UD, and a staged character of erosive-ulcerous transformation in the GDS M, with the hypercoagulative sings being present at the level of hemomicrocirculation. Progressing structural and functional changes in ECSS parallel to stages of development and severity of the UD GDS course suggest their interrelationship to pathosanogenesis during all stages of erosive-ulcerous transformation. At the molecular level, this may reflect directly the course of staged ulceration and a point of activation of processes of physiological defence, this being of diagnostic as well as prognostic value. The enterochromaffin-serotonin conception of pathosanogenesis of staged erosive-ulcerous transformation in GDS M supplements, rather than contradicts to a current infectious Helicobacter hypothesis of ulcerogenesis. Thus, evaluation of ECSS structural and functional status in UD GDS is to be part of a diagnostic algorithm testing severity of the course as well as of a monitoring of treatment and prognostication.
