title: Gastric infection by Helicobacter pylori and antral gastritis in hyperglycemic obese and in diabetic subjects.
abstract: The aim of this work was to ascertain if diabetes and obesity can affect gastric colonization by Helicobacter pylori. 59 hospitalized subjects with dyspepsia and endoscopic antral gastritis were selected. They were divided into three groups: I) 13 patients with normal body weight and without disease other than gastritis (control group); II) 15 patients with essential obesity of whom 10 had impaired glucose tolerance (IGT); III) 31 patients with type II diabetes mellitus, of whom 14 were obese. Three gastric biopsies were obtained from each patient for histologic examination and H. pylori detection by means of rapid urea test, culture and histological evidence of Helicobacter-Like Organisms (HLO). Age, sex, blood glucose, cholesterol, triglycerides, HDL-cholesterol, basal gastrine, duration of illness, body weight were statistically analysed. Differences between the three groups were not statistically significant. There was a higher prevalence of H. pylori infection both in obese and in diabetic patients with respect to control subjects. Prevalence became still higher in obese patients with impaired glucose tolerance. Among the three tests used for the detection of H. pylori, culture and rapid urea were reliable and specific, while the histologic test was highly sensitive but barely specific. Our data suggest that both obesity and type II diabetes may be associated with an increased incidence of H. pylori-colonization. This could be related to the reduced gastric motility observed in both pathologies and chemical changes in gastric mucosa following non-enzymatic glycosylation processes.
