Analysis of drug resistance and treatment efficacy of Helicobacter pylori infection in children
Abstract
Objective: To investigate the antibiotic resistance of Helicobacter pylori (Hp) and to evaluate the eradication efficacy of individualized treatment for Hp in children. Methods: A retrospective cohort study was conducted on 227 children who visited the Department of Gastroenterology, Capital Center for Children's Health, Capital Medical University from June 2022 to December 2023 due to gastrointestinal symptoms. All patients underwent gastroscopy and tested positive on 13C-urea breath testing. They were grouqed according to the Hp culture and drug susceptibility test. Children with positive Hp culture received personalized treatment based on the results of their drug sensitivity tests, while the other children who didn't undergo Hp culture received empirical treatment. The effects of different treatment groups was compared by chi-square test or Fisher exact probability test. Results: A total of 227 children with Hp infection (121 males and 106 females) were included, with the age of 11.7 (8.9, 13.6) years. Among the 131 samples submitted for testing, 105 cases (80.1%) had positive results. Only 9.5% (10/105) of patients were sensitive to 6 antibiotics. The resistance rates to clarithromycin, metronidazole and levofloxacin were 90.5% (95/105), 86.7% (91/105) and 22.9% (24/105) respectively. The resistance rate to both clarithromycin and metronidazole was 77.1% (81/105). The resistance rate to both levofloxacin and metronidazole was 19.0% (20/105). The resistance rate to both…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 227 participants or records.
