Clinical Trial: Importance of Cytokines in Peptic Ulcer Disease: Implications for Treatment
Study Status: Completed
Recruit Status: Completed
Study Type: Interventional
Official Title: A Clinical Study of the Efficacy of Esomeprazole or Rabeprazole on the Pattern of Release of Pro- and Anti-inflammatory Cytokines From Gastric Mucosa of Patients With Peptic Ulce
Brief Summary: Although all PPIs are effective, there are some differences in their clinical performance, particularly in terms of the degree and speed of gastric acid suppression. Few data are also available about their effect of the pathophysiological mechanisms of gastritis and peptic ulcer disease. Aim of the present study is to investigate the effect of therapy with esomeprazole or rabeprazole on the mechanism of pathogenesis of gastritis and particularly on the pattern of release of pro- and anti- inflammatory cytokines associated to peptic ulcerative process by the gastric mucosa.
Detailed Summary:
Although all PPIs are effective, there are some differences in their clinical performance, particularly in terms of the degree and speed of gastric acid suppression. Few data are also available about their effect of the pathophysiological mechanisms of gastritis and peptic ulcer disease.
Triggering receptor expressed on myeloid cells (TREM)-1 is a recently discovered receptor expressed on the surface of neutrophils and monocytes. Engagement of TREM-1 has been reported to trigger the synthesis of proinflammatory cytokines. A soluble form of TREM-1, named sTREM-1, was observed and identified at significant levels in serum samples from patients with disease of the gastrointestinal tract inflammatory bowel disease. rendering interest about the implication of sTREM-1 in their pathogenesis.
sTREM-1 was also found elevated in the gastric juice of patients with peptic ulcer disease being correlated to the degree of the infiltration of the gastric mucosa by neutrophils.
Published data of our group elicit that sTREM-1 secretion is a crucial parameter for evolution from chronic gastritis to peptic ulcer disease. Samples of biopsies of gastric mucosa were cultured in the absence/presence of endotoxins showing that the inflamed mucosa was a potent secretor of sTREM-1 whatever ceased to exist post-antisecretory treatment.
Aim of the present study is to investigate the effect of therapy with esomeprazole or rabeprazole on the mechanism of pathogenesis of gastritis and particularly on the pattern of release of pro- and anti- inflammatory cytokines associated to peptic ulcerative process by the gastric mucosa.
