In the study population of 192 patients, 118 histological studies showed active non-atrophic chronic gastritis, 74 patients had chronic atrophic gastritis with a 73% prevalence of Helicobacter pylori infections, 47 patients had intestinal metaplasias. Of these 52% had complete, or type I, intestinal metaplasia and 48% had incomplete or mixed typed II and III intestinal metaplasias. Three patients had mild dysplasia and were positive for Helicobacter pylori. The prevalence of chronic atrophic gastritis was 38.6%, the prevalence of intestinal metaplasia was 24.4%, and that of mild dysplasia 1.5% Table 1.
