Background : Helicobacter pylori (HP) is under investigation for its potential role in postoperative complications. While some studies indicate no impact, they often cite short or incomplete follow-up. This study aims to compare 1-year outcomes in groups with and without active HP infection after bariatric surgery, also assessing HP prevalence in postoperative specimens of sleeve gastrectomy (SG) patients. Methods : Conducted between May 2020 and May 2021, this study involves both retrospective and prospective data collection from 93 eligible SG patients. Demographics, surgical outcomes and follow-up results (including complications; weight and BMI at 3, 6 and 12 months post-SG) were extracted. Results : No statistically significant differences in body weight were observed at 3 ( p = 0.3757), 6 ( p = 0.1422) or 12 ( p = 0.2737) months post-surgery between the HP-positive (Group A) and non-infected (Group B) groups. Group A experienced significant reductions in body weight at 6 and 12 months ( p < 0.0001), while group B showed significant reductions at 3, 6 and 12 months ( p < 0.0001), with additional decreases at 6 and 12 months post-surgery compared to 3 months. No significant differences in overall surgery-related side effects were observed between the groups. Conclusions : Patients with active HP infections undergoing SG displayed comparable rates of short- and long-term complications to the non-infected group. Active HP infection did not impact body weight loss outcomes at 12 months, but it may potentially slow it down in the initial three-month post-surgery period. This underscores the need to consider eradication while maintaining awareness of the potential side effects associated with the process.

Introduction: The aim of the study was to investigate the impact of the COVID-19 pandemic on bariatric care from the patients' point of view. The COVID-19 pandemic has perturbed the functioning of healthcare systems around the world and led to changes in elective surgical care, with bariatric procedures being postponed until the end of pandemic. There is no data in the literature about the effect of a new epidemiological situation on bariatric patients., Methods: The study was designed as an online survey containing multiple open questions about bariatric care during the COVID-19 pandemic. The survey was conducted among pre- and postoperative bariatric patients., Results: Out of 800 respondents, 74.53% felt anxiety about their health in regard to the present epidemiologic state. Some (72.25%) were aware of the fact that obesity was an important risk factor that could impair the course of the COVID-19 disease. Almost 30% of respondents admitted having put on weight, significantly more in the group of preoperative patients (43.8% vs 22.69%; p < 0.001). Only 20.92% of patients had a possibility of continuing direct bariatric care; 67.3% of patients had an opportunity of remote contact with a bariatric specialist, including online consultations, teleconsultations and social media meetings., Conclusions: Limited access to medical care and quarantine lockdown may result in a deterioration of long-time operation outcomes and lower weight losses. Patients should be encouraged to profit from online consultations with specialists and telemedicine to reduce the negative effects of the pandemic on their health.

Bariatric surgery leads to metabolic benefits in patients with obesity, but their mechanisms are not well understood. The appropriate composition of serum amino acids (AA) is important for sufficient supply of these components into various tissues and organs. Obesity leads to alterations in serum AA concentrations. The aim of this study was to examine the effect of one anastomosis gastric bypass (OAGB), a promising type of bariatric surgery, on serum AA concentrations, which were assayed by LC-MS in serum of 46 bariatric patients prior to and 6-9 months after OAGB, as well as in 30 lean control subjects. The results were analyzed by principle components analysis and metabolic pathway analysis. PCA analysis showed that OAGB led to normalization of serum AA concentrations of patients with obesity to a pattern similar to the control subjects, and the concentrations of essential AA remained decreased after OAGB. Changes of individual AA and their associated metabolic pathways were also presented. OAGB caused normalization of the AA profile, which may contribute to improvement of glucose homeostasis and reduction of cardiovascular risk. Considering decreased essential AA concentrations after OAGB, increased intake of high protein food should be recommended to the patients after this type of bariatric surgery.
