{Abstract}: <B>BACKGROUND: </B>Helicobacter pylori may be found during upper gastrointestinal endoscopy (UGE) performed to diagnose celiac disease (CeD), inflammatory bowel disease (IBD), and eosinophilic esophagitis (EoE). We aimed to describe the frequency of H. pylori in children undergoing UGE for CeD, IBD, and EoE and the number of children receiving eradication treatment.<BR><B>METHODS: </B>A retrospective multicenter study from 14 countries included pediatric patients diagnosed with CeD, IBD, and EoE between January 2019 and December 2021.<BR><B>METHODS: </B>age, gender, hematologic parameters, endoscopic, histologic, and H. pylori culture results, and information on eradication treatment.<BR><B>RESULTS: </B>H. pylori was identified in 349/3890 (9%) children [167 (48%) male, median 12 years (interquartile range 8.1-14.6)]. H. pylori was present in 10% (173/1733) CeD, 8.5% (110/1292) IBD and 7.6% (66/865) EoE patients (p = NS). The prevalence differed significantly between Europe (Eastern 5.2% (28/536), Southern 3.8% (78/2032), Western 5.6% (28/513)) and the Middle East 26.6% (215/809) [odds ratio (OR) 7.96 95% confidence interval (CI) (6.31-10.1) p < 0.0001]. Eradication treatment was prescribed in 131/349 (37.5%) patients, 34.6% CeD, 35.8% IBD, and 56.1% EoE. Predictors for recommending treatment included erosions/ulcers [OR 6.45 95% CI 3.62-11.47, p < 0.0001] and nodular gastritis [OR 2.25 95% CI 1.33-3.81, p 0.003]. Treatment rates were higher in centers with a low H. pylori prevalence (<20%) [OR 3.36 95% CI 1.47-7.66 p 0.004].<BR><B>CONCLUSIONS: </B>Identifying H. pylori incidentally during UGE performed for the most common gastrointestinal diseases varies significantly among regions but not among diseases. The indications for recommending treatment are not well defined, and less than 40% of children received treatment.
