Abstract

Background:Lymphocytic duodenosis (LD) defined as increased intraepithelial lymphocytes >25 intraepithelial lymphocytes (IELs) per 100 epithelial cells with normal villous architecture is associated with many gastrointestinal (GI) disorders. We aim to assess the rate and outcome of LD in children and perform a systematic review.Method:We reviewed all children (<18 years) who underwent esophagogastroduodenoscopy (EGD) with duodenal biopsy between January 2000 and June 2019 to identify LD cases and control group. Demographics, clinical, and pathologic information were reviewed and recorded. A systematic review including our findings was performed.Results:During the study period 12,744 children underwent an EGD with biopsies. Of those, we identified 426 children with LD (3%) and 474 controls. The median age in years was 10.7 and 12.6 and there were 254 (60%) and 278 (59%) girls in the LD and control group, respectively. The most common presenting symptoms in both groups were abdominal pain (52%), gastroesophageal acid reflux disease (18%), diarrhea (16%), and vomiting (12%). Diarrhea (21% vs 12%, P < 0.001) and constipation (2% vs 0.4%, P = 0.021) were statistically different between the LD and control group, respectively. Median follow-up (range) is 3.6 (0.0, 190.9) and 3.1 (0.0, 194.2) in the LD and control group, respectively. CD (5% vs 0%, P < 0.001), Crohn disease (9% vs 3%, P = 0.003) and Helicobacter pylori gastritis (3% vs 1%, P = 0.021) were more common in the LD group.Conclusions:The Rate of LD in children is similar to reported rate in adults. In the absence of Crohn disease, CD or H. Pylori, LD seems to be a benign and transient histologic finding in children.
