Purpose
Helicobacter Pylori (HP) infection is systematically screened for before carrying out bariatric surgery. Criteria to determine “at risk” patients and avoid systematic screening are lacking. We evaluated the prevalence of HP infection and associated predictive factors in a population of patients with class II and III obesity volunteering for bariatric surgery.
Materials and Methods
Observational, cross-sectional study of patients included in the severe obesity outcome network (SOON) cohort. All patients underwent HP screening. The relationship between plasma metabolic parameters and vitamin levels, medical history and socio-economic parameters, and HP infection was analyzed.
Results
Data from 201 patients, median age 43 years [IQR 35; 52] (81% female) were analyzed. Forty-four patients (22%) were infected with HP and successfully treated, most with a single course of treatment, either combined antibiotics or Pylera®. HP infection was associated with social precariousness as defined by the French “Evaluation de la Précarité et des Inégalités de santé dans les Centres d’Examens de Santé” (EPICES) score (Evaluation of Poverty and Health Inequalities in Health-Assessment Centers) (OR, 1.027; 95% CI, 1.008–1.046; p < 0.004) and with higher levels of vitamin B12 (OR, 1.004; 95% CI, 1.001–1.007; p < 0.007).
Conclusion
The prevalence of HP infection was 22% and was associated with social precariousness. Plasma glucose/insulin and lipid/lipoprotein profiles, liver enzymes or vitamin deficiencies were not associated with HP infection. The number of characteristics associated with HP infection was insufficient to define patients who do not require HP screening before bariatric surgery.
