ABSTRACT
BACKGROUND:
The global prevalence of obesity is increasing and represents a major public health challenge. However, there is a paucity of data regarding Helicobacter pylori (H pylori) eradication in people with obesity. The aim of the study is to examine the influence of obesity degree on H. pylori eradication in patients undergoing bariatric and metabolic surgery.METHODS:
A post hoc analysis was conducted in a cohort of 204 adults patients (129 individuals diagnosed with obesity, 75 normal weight) H. pylori positive, included in two multicenter, prospective studies. Patients underwent a 14-day quadruple concomitant treatment, and H. pylori eradication was assessed using the 13C-urea breath test. The cohort was stratified according to body mass index (BMI), and statistical analyses were performed using chi-squared test, Kruskal-Wallis test, and logistic regression.RESULTS:
Eradication rates were significantly lower in patients with obesity compared with normal weight individuals (68.2% vs. 88.0%, OR 0.29, 95% CI 0.13-0.63, p < 0.01). Furthermore, within the population diagnosed with obesity, the degree of obesity correlated with decreased eradication rates, with class 3 (BMI 40.0-49.9) and class 4 (BMI ≥ 50.0) obesity showing the lowest rates (67% and 51%, with an OR 0.28 and 0.15 respectively, p < 0.01).CONCLUSIONS:
Our results indicate that obesity may influence H. pylori eradication, especially among severe obesity patients undergoing bariatric surgery, which could have implications for the development of ulcers and gastritis as well as the risk of gastric cancer. Tailored eradication strategies may be necessary to improve treatment efficacy in this population.
