Association between celiac disease and gastritis; how commonis it in paediatric age group?

Background: Celiac disease (CD) has been associated with multiple forms of gastritis in adult and pediatric patients. Gastritis types include chronic active gastritis (CAG), chronic inactive gastritis (CIG), or lymphocytic gastritis (LG). the objective of the study is to evaluate the incidence of different forms of gastritis in celiac patients. Methods: A retrospective chart review was done for confirmed celiac patients in a tertiary carecenter in Jeddah, Saudi Arabia, from January 2012 to December 2019. A total of 450 celiac patients. All patients with gastric in addition to duodenal biopsies taken were included. All biopsies were reviewed by a gastrointestinal pathologist. SPSS Version 2.2 and the chi-square test were used for the Statistical analysis. Results: A total of 366 patients their biopsies were identified, other 84 patients were excluded because they are adults, above the age of 18 years. Age 2-40 years with 65% males. About half of patients, 177 patients had normal gastric biopsies (48.4%). The other 189 (51.6%) patients had different types of gastritis. Nine patients had lymphocytic gastritis (2.5%). Helicobacter pylori gastritis is seen in 87 (23.8%) patients with different types of gastritis including CA (19.7%), CIG (2.5%), and chronic atrophic gastritis (1.6%). Conclusion: Celiac disease is commonly associated with different types of gastritis. Lymphocytic gastritis was surprisingly lower thanusual in our data (2.5%), incidence usually of 5%. Our incidence of helicobacter pylori gastritis is higher than most previous pediatric cohorts. More data is needed to assess the effect of a gluten-free diet on gastritis.
