Efficacy and Safety of Helicobacter pylori Eradication in the Elderly: A Propensity Score Matching Analysis / 胃肠病学

ABSTRACT

Background: The benefits and risks of eradicating Helicobacter pylori (Hp) should be balanced in aged people. Aims: To investigate the efficacy, safety and antibiotic resistance status of Hp eradication treatment in the elderly. Methods: Four cohorts of subjects who received Hp eradication treatment in randomized controlled trials conducted in Chongqing Daping Hospital were reviewed; the demographic and clinical data were extracted and recorded. Propensity score matching was performed to select comparable elderly group (≥60 years old) and non-elderly group (0.05). Furthermore, there were no significant differences in the Hp eradication rates in terms of gender, cigarette smoking, alcohol consumption, comorbidities (hypertension, diabetes, surgical history, and inflammation), compliance, etc. in the elderly group (all P> 0.05). But in retreated elderly subjects, the resistance rate of clarithromycin was higher than that in naïve elderly subjects (P<0.05). Smoking and poor compliance were identified as independent risk factors for Hp eradication by multivariate Logistic regression analysis. Conclusions: Hp eradication in the elderly demonstrates comparable efficacy and safety with non-elderly subjects. Clarithromycin-containing regimens are not recommended for empirical retreatment in aged people.
