Propensity score matched at a 1:2 ratio – for age, sex and body mass index was performed for the two groups, yielding a DM group with 147 patients and a non-DM group with 249 matched controls for analysis. Urea breath test was performed 6–8 weeks after treatment. Clinical and laboratory parameters were collected for identifying factors associated with failed eradication.Results: H. Pylori was eradicated in 74.1% (95% confidence interval [CI] =66.2–81.0) of the DM group and 85.3% (95% CI =80.8–89.4) of the non-DM group (p=0.005). Of 51 gastric biopsy samples cultured for H. pylori, 41 were positive. In the DM group, the rates of resistance to amoxicillin, clarithromycin, levofloxacin, and tetracycline were 0%, 50.0%, 50.0% and 0%, respectively. In the non-DM group, the comparable proportions were 2.9%, 17.1%, 22.9%, and 0%, respectively. Univariate analysis revealed that DM (Odds ratio [OR], 1.771, 95% CI, 1.167–2.668, p=0.006), clarithromycin resistance (OR, 15.273; 95% CI, 1.687–138.269; p=0.015), and amoxicillin resistance (OR, 4.672; 95% CI, 2.431–8.979; p90% eradication.Keywords: Helicobacter pylori infection, standard triple therapy |
