Background Lymphocytic gastritis (LG) is an uncommon entity with varying symptoms and endoscopic appearances. This condition, as well as two forms of H. pylori-negative gastritis [chronic active gastritis (CAG) and chronic inactive gastritis (CIG)], appears to be more common in patients with coeliac disease (CD) based on single-centred studies. Aim To compare the prevalence of LG, CAG and CIG among those with normal duodenal histology (or nonspecific duodenitis) and those with CD, as defined by villous atrophy (Marsh 3). Methods We analysed all concurrent gastric and duodenal biopsy specimens submitted to a national pathology laboratory during a 6-year period. We performed multiple logistic regression to identify independent predictors of each gastritis subtype. Results Among patients who underwent concurrent gastric and duodenal biopsy (n = 287 503), the mean age was 52 and the majority (67%) were female. Compared to patients with normal duodenal histology, LG was more common in partial villous atrophy (OR: 37.66; 95% CI: 30.16-47.03), and subtotal/total villous atrophy (OR: 78.57; 95% CI: 65.37-94.44). CD was also more common in CAG (OR for partial villous atrophy 1.93; 95% CI: 1.49-2.51, OR for subtotal/total villous atrophy 2.42; 95% CI: 1.90-3.09) and was similarly associated with CIG (OR for partial villous atrophy 2.04; 95% CI: 1.76-2.35, OR for subtotal/total villous atrophy 2.96; 95% CI: 2.60-3.38). Conclusions Lymphocytic gastritis is strongly associated with coeliac disease, with increasing prevalence correlating with more advanced villous atrophy. Chronic active gastritis and chronic inactive gastritis are also significantly associated with coeliac disease. Future research should measure the natural history of these conditions after treatment with a gluten-free diet.
