摘要

Purpose

To assess the effects of Helicobacter pylori (HP) eradication with an omeprazole, clarithromycin, amoxicillin, and metronidazole (OCAM) regimen on the metabolic profile and weight loss 12 months after bariatric surgery (BS).

Methods

Retrospective analysis of a prospective cohort of patients with morbid obesity undergoing BS. HP presence was tested preoperatively by gastric biopsy and treated with OCAM when positive. Short-term metabolic outcomes and weight loss were evaluated.

Results

HP infection was detected in 75 (45.7%) of the 164 patients included. OCAM effectiveness was 90.1%. HP-negative patients had a greater reduction in glucose levels at 3 (−14.6 ± 27.5 mg/dL HP-treated vs −22.0 ± 37.1 mg/dL HP-negative, p=0.045) and 6 months (−13.7 ± 29.4 mg/dL HP-treated vs −26.4 ± 42.6 mg/dL HP-negative, p= 0.021) and greater total weight loss (%TWL) at 6 (28.7 ± 6.7% HP-treated vs 30.45 ± 6.48% HP-negative, p= 0.04) and 12 months (32.21 ± 8.11% HP-treated vs 35.14 ± 8.63% HP-negative, p= 0.023).

Conclusions

Preoperative treatment with OCAM has been associated to poorer glycemic and weight loss outcomes after BS. More research is needed on the influence of OCAM on gut microbiota, and in turn, the effect of the latter on metabolic and weight loss outcomes after BS.
