Patients with H. pylori-positive LGIN had significantly higher concentrations of serum EGF and lower concentrations of serum PGE2 versus patients with H. pylori-negative LGIN. Serum EGF and PGE2 levels in patients with LGIN were not significantly associated with disease type, but were significantly associated with disease severity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>H. pylori infection was associated with chronic gastritis type (endoscopic classification) and disease severity.
