Abstract:
Objective:To investigate the correlation between long-term use of low-dose aspirin and Helicobacter pylori(HP)infection in elderly people and its effectiveness on HP eradication and recurrence.Methods:A retrospective analysis was conducted on 2 834 elderly people aged 60 and above who underwent the C 13-or C 14-urea breath test(UBT)for the first time in the Physical Examination Center of the First Hospital of Lanzhou University between March 2010 and December 2019.According to the results of UBT, people were divided into an HP infection group with 1 510 patients and a non-HP infection group with 1 324 patients.Univariate and multivariate Logistic regression analysis were used to investigate the relationship between aspirin use and HP infection.Additionally, in a prospective case-control analysis, 544 elderly hypertensive patients diagnosed with HP infection between March 2015 and December 2020 were selected and divided into an aspirin group(402 cases)and an observation group(142 cases), based on whether aspirin was used.The aspirin group was further divided into a 1 to <2 years group(134 cases), a ≥2 to <5 years group(142 cases)and a ≥5 years group(126 cases)based on the duration of aspirin treatment.The rates of HP eradication, safety and one-year post-treatment HP recurrence with bismuth-containing quadruple therapy were compared. Results:The overall HP infection rate was 53.28%(1 510/2 834).Univariate analysis showed that the infection rate in women was higher than in men[56.86%(584/1 027) vs.51.25%(926/1 807), χ2=8.307, P=0.004].The infection rate in aspirin users was higher than in non-aspirin users[57.29%(920/1 606) vs.48.05%(590/1 228), χ2=23.866, P<0.001], with no significant difference between aspirin use for 1-<2 years, ≥2-<5 years and ≥5 years[60.22%(162/269) vs.56.4%(273/484) vs.56.86%(485/853), χ2=1.166, P=0.558].Fasting blood glucose levels in the HP infection group were higher than in the non-HP infection group[(5.92±1.78)mmol/L vs.(5.77±1.40)mmol/L, t=2.317, P=0.021].Multivariate Logistic regression analysis showed the risk of HP infection in women was higher than in men( OR=1.254, 95% CI: 1.075-1.464, P=0.004).Long-term aspirin use increased the risk of HP infection( OR=1.450, 95% CI: 1.249-1.684, P<0.001).Among the 544 cases selected for eradication therapy, 522 completed the treatment protocol, with 479 achieving successful eradication.The overall eradication rate was 91.76%(479/522)according to per-protocol(PP)analysis and 88.05%(479/544)according to intention-to-treat(ITT).After 1 year, 472 cases underwent reexamination, with an overall recurrence rate of 3.6%(17/472).There was no statistical significance in the eradication rate and recurrence rate among the groups with different durations of aspirin treatment and the observation group. Conclusions:Long-term use of low-dose aspirin increases the risk of HP infection in the elderly, but does not affect the eradication rate and one-year recurrence rate of bismuth-containing quadruple therapy.Therefore, periodic screening and eradication of HP should be performed.
