Background: The endoscopic pattern of antral nodularity is a peculiar finding in children with Helicobacter pylori infection. The aim of this study was to determine whether this finding is related to more severe gastritis.
Methods: One hundred seventy-four consecutive children (median age 8.7 years) referred for gastroscopy were studied. Biopsy specimens from the antrum and body of the stomach were taken to assess H pylori status, gastritis score, and lymphoid follicles. Clinical diagnosis, major symptoms and endoscopic findings were recorded.
Results: Eighty-four (48%) children (median age 10.5 years) had evidence of H pylori infection. The endoscopic pattern of antral nodularity was found only in children infected with H pylori (34/84, 40.5% vs. 0/90, 0%, p < 0.0001% 100% specificity, 40.5% sensitivity). Among all children infected with H pylori, the gastritis score was higher (p < 0.0001) in those with antral nodularity (n = 34) than in those without (n = 50). Completely normal gastric mucosal histology was never found in children infected with H pylori with antral nodularity. The presence and number of lymphoid follicles was strongly related to the finding of antral nodularity (p < 0.01).
Conclusions: The endoscopic pattern of antral nodularity identifies children with H pylori infection, severe gastritis, and increased lymphoid follicles.

Article Synopsis
- The study investigates the effectiveness and safety of various antibiotic therapies for eradicating Helicobacter pylori (H. pylori) infection in children, focusing on options like triple, sequential, hybrid, concomitant, and ciprofloxacin-based therapies.
- A randomized trial involving 200 children (ages 3-16) revealed that ciprofloxacin-based triple therapy achieved the highest eradication rate at 90%, compared to lower rates for other therapies, with no significant difference in adverse effects.
- The conclusion highlights that ciprofloxacin-based triple therapy is the most effective and safe option for treating H. pylori infection in children, while the other treatment options do not significantly outperform traditional triple therapy.*

Article Synopsis
- - The study analyzed treatment decisions for H. pylori infection in children using data from the EuroPedHp Registry, focusing on various factors influencing whether or not therapy was administered, especially regarding gastrointestinal (GI) comorbidities.
- - Out of 1165 pediatric patients, those with GI comorbidities were significantly less likely to receive eradication treatment (only 57%) compared to those with no comorbidities (89%) despite having similar symptoms and conditions.
- - The findings suggest that H. pylori-infected children with GI issues had a much lower chance (75% reduced) of receiving treatment, indicating no rationale for different management approaches based on GI comorbidities in pediatric patients with confirmed infections.
Collagenous gastritis is a rare and chronic inflammatory condition of undetermined etiology characterized histologically by thickened subepithelial collagen bands and increased intraepithelial lymphocytes. Here, we present a collagenous gastritis case in a 16-year-old female with chronic abdominal pain, persistently elevated fecal calprotectin (507 and 796 mcg/g), and resolved iron deficiency anemia. The patient's history, laboratory tests, endoscopy, and magnetic resonance imaging ruled out common causes of elevated fecal calprotectin, including and gastrointestinal infections, medications, celiac disease, and inflammatory bowel disease, as well as less common causes such as collagenous .

Article Synopsis
- * A study compared gastric tissue samples from NG and AG patients, revealing distinct patterns of methylation, especially in tumor-suppressor genes like CDH1 and DAPK1, which were more methylated in NG patients.
- * The research suggests that NG induces significant methylation changes in the stomach's antrum, contributing to an increased risk of gastric cancer due to the alteration of gene expression and methylation patterns.
