Long-term Observation of Subjects with Normal Mucosa and with Superficial Gastritis: Results of 23-27 Years’ Follow-up Examinations

Abstract

261 subjects with a normal body mucosa or with superficial gastritis used as controls for an atrophic gastritis series have been followed up for 23-27 years. Of them, 41 died during the earlier and 63 during the present follow-up period. In all, 141 subjects were reexamined in 1976-1977 and 16 answered a questionnaire. None of the subjects had gastric carcinoma or an adenomatous polyp. One patient diagnosed and reported earlier had died of gastric carcinoma during the present period of observation. Of the subjects with normal body mucosa 58% had developed superficial and 14% atrophic gastritis. Of those with superficial body gastritis 42% had developed atrophic gastritis and 18% showed an improvement of the gastritic changes. It should be noted, however, that earlier examinations were performed with blind biopsy and the present with direct vision gastroscopic biopsy. The state of the antral and body mucosa was similar in 53%, antral changes dominated in 33% and the changes in the body in 14%. Intestinal metaplasia was found in 36%. atypical epithelium in 6%, parietal cell antibodies in 0.5% and intrinsic factor antibodies in 0.5%. The fasting serum gastrin level was above 100 ng/ml in 10%. Only 2 cases fulfilled the morphological, functional and immunological criteria of type A gastritis. The present controls differed from the atrophic gastritis series in that the topography of gastritis was different and in that the incidence of metaplasia, atypia, gastric antibodies and high serum gastrin levels was markedly lower.
