ABSTRACT
BACKGROUND:
The diagnosis of Helicobacter pylori (H. pylori) infection in children remains challenging with the lack of a rapid, cost-effective, and highly accurate diagnostic method. Consequently, this study aimed to investigate the accuracy of the combination of gastric nodule and rapid urease test (RUT) as a diagnostic method for H. pylori infection in children.METHODS:
The study included participants who underwent a thorough examination, including gastroscopy, a 13C breath test, RUT, and pathological methylene blue staining, with the gold standard for diagnosing of H. pylori infection being a positive result from both pathological methylene blue staining and 13C breath test. The sensitivity, specificity, positive and negative predictive values, and accuracy of the diagnostic methods were calculated.RESULTS:
The accuracy of the different tests for H. pylori infection was evaluated in 2202 participants. A total of 730 (33.2%) children were diagnosed with H. pylori infection (pathological methylene blue staining and 13C breath test, both positive). Gastric nodule had a sensitivity of 87.1% and a specificity of 93.1%, whereas combining gastric nodule and RUT in parallel had the higher accuracy of 95.4%. The accuracy of gastric nodule diagnosis was higher in younger age groups and increased after excluding patients with a history of anti-H. pylori treatment.CONCLUSIONS:
The findings of this study suggest that gastric nodules, particularly when combined with RUT, can be a valuable predictor of H. pylori infection in children, offering a simple and feasible alternative to other invasive methods.Palavras-chave
