AIM: To investigate the natural history of lymphocytic gastritis (LG) and its relation to Helicobacter pylori infection and to coeliac disease using serology, duodenal biopsy and a small intestinal permeability test. METHOD: Twenty two patients diagnosed as having LG between 1984 and 1994 were investigated by upper gastrointestinal endoscopy at which gastric and duodenal biopsy specimens were taken for histological assessment and immunohistology. Serum was collected for measurement of anti-H pylori, anti-gliadin and anti-endomysial antibodies. A lactulose/mannitol absorption test was performed within one week of endoscopy. Control groups were studied by histology, serology and permeability tests. RESULTS: Three patients had been recently diagnosed as having LG while 15 still had the condition after a mean of 13.9 (range two to 38) months. LG involved the antrum alone in three patients, antrum and body in seven, body alone in six, and gastric remnant in two. Gastroduodenal intraepithelial lymphocytes (IELs) were T cells and predominantly of T suppressor (CD8) type. Duodenal IELs were increased compared to age/sex matched controls with chronic gastritis. Four patients had duodenal villous atrophy. Four patients no longer had LG after a mean of 29.3 (10-70) months but had increased gastroduodenal IELs. H pylori was present in four (22%) of 18 patients with LG but H pylori serology was positive in 11 (61%) of 18. There was no difference in seropositivity when compared with age/sex matched controls with dyspepsia. Eleven of 20 patients with LG tested had abnormal lactulose/mannitol absorption (v none of 22 controls with chronic gastritis). Four patients with LG, all with villous atrophy, were seropositive for IgA endomysial antibody. CONCLUSIONS: The persistence of LG with time, the association with increased duodenal IELs and abnormal small intestinal permeability suggests LG may be a manifestation of a diffuse lymphocytic gastroenteropathy related to sensitivity to gluten or some other agent.
