Abstract:
Objective:To investigate the correlation between long-term statin use and Helicobacter pylori( Hp)infection in the elderly, and to compare the effects of rosuvastatin combined with bismuth-containing quadruple therapy for Hp eradication on lipid levels in elderly patients with mixed hyperlipidemia. Methods:A retrospective analysis was conducted on 1 181 elderly patients with hyperlipidemia, cardiovascular and cerebrovascular diseases, and peripheral arterial disease who were treated at the First Hospital of Lanzhou University between March 2019 and December 2023.According to the results of carbon 14 urea breath test(C 14-UBT), the subjects were divided into the Hp infection group and the non- Hp infection group.Multivariate logistic regression methods were used to analyze the correlation between Hp infection and statin use.A prospective case-control analysis was conducted on 109 patients with mixed hyperlipidemia and Hp infection treated during the same period, they were treated with rosuvastatin combined with bismuth-containing quadruple therapy for Hp eradication.The successful eradication people were selected as the eradication group (n=95). Patients with hyperlipidemia and Hp infection unwilling eradication was selected as the control group (n=109), and treated with rosuvastatin.Changes in lipid levels were compared over a consecutive 6-month period. Results:The overall Hp infection rate was 53.94%(637/1 181). Univariate analysis showed that the infection rate in women was higher than in men.Body mass index(BMI), low-density lipoprotein cholesterol(LDL-C), fasting blood glucose(FBG)levels in the Hp(+ )group were higher than in the Hp(-)group.Long-term low-dose aspirin users had a higher infection rate than non-users.The infection rate was lower in statin users than in non-users[42.65%(374/877) vs.55.59%(169/304), χ2=15.234, P<0.001]. Multivariate analysis showed that women had a higher infection risk than men ( OR=1.441, 95% CI: 1.102-1.729, P=0.011). Higher FBG and LDL-C levels increased the risk of Hp infection ( OR=1.406, 95% CI: 1.271-2.286, P<0.001, OR=1.118, 95% CI: 1.017-1.387, P=0.010). Aspirin use increased the risk of Hp infection( OR=1.162, 95% CI: 1.034-1.294, P=0.021), while statin use reduced the risk of Hp infection ( OR=0.177, 95% CI: 0.018-0.311, P<0.001). The Hp eradication rate was 87.16%(95/109). At 1-and 2-months post-eradication, statistically significant differences were observed between the eradication and control groups in LDL-C, total cholesterol(TC), changes from baseline, and target achievement rates(all P<0.05). At 1-month post-eradication, a statistically significant difference was observed in high-density lipoprotein cholesterol(HDL-C) levels between the two groups.Additionally, at both 1-and 2-months post-eradication, significant differences were found in the changes in HDL-C levels from baseline between the eradication group and the control group(all P<0.05). Conclusions:Long-term statin use in the elderly may reduce the risk of Hp infection.Rosuvastatin combined with a standard quadruple therapy does not improve the Hp eradication rates in elderly patients with mixed hyperlipidemia, but it facilitates short-term achievement of cholesterol targets.
