Background: Helicobacter pylori (HP) infection of the gastric mucosa may be involved in the development of insulin resistance (IR). 

Objectives: To investigate the association between HP status in stomach biopsies and weight reduction in patients who underwent laparoscopic sleeve gastrectomy (LSG). 

Methods: In this retrospective analysis of medical charts, all patients who underwent LSG for weight reduction and had at least 1 year of follow-up were included. HP status was ascertained by two to four biopsies of the removed stomach. 

Results: The study group comprised 70 patients; their mean age was 45.9 ± 11.9 years and 31.9% were males. Fourteen patients (20%) tested positive for HP colonization in gastric mucosa. HP status was not associated with age or smoking status. No difference was noted in the rate of diabetes mellitus (DM) or hypertension, but patients with HP had lower rates of hyperlipidemia (0 vs. 29 patients, 52%, P < 0.001). Patients lost an average of 10.5 kg/m2 after 12 months of follow-up, and no difference was noted between HP-positive and HP-negative patients. The rate of DM control was also similar between HP-positive and HP-negative patients at baseline (33.3 vs. 29.4, P = NS) and at 12 months of follow-up (70% vs. 50%, P = NS). 

Conclusions: HP status was not associated with changes in metabolic profiles and co-morbidity status, or in the efficacy of LSG. 

 

Background: There is a striking increase in the number of people with metabolic syndrome (MetS) as a result of the global epidemic of obesity and diabetes. Increasing evidence suggests that uric acid may play a role in MetS.

Objectives: To assess the prevalence of MetS in a large cohort from Israel and its association with hyperuricemia using the latest three definitions of MetS.

Methods: We conducted a retrospective analysis of the database from a screening center in Israel, using the revised National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III), the International Diabetes Federation (IDF) and the Harmonizing definitions of MetS, to assess 12,036 subjects with an age range of 20–80 years.

Results: The mean age of the study sample was 46.1 ± 10.2 years and 69.8% were male. The prevalence of MetS was 10.6%, 18.2% and 20.2% in the revised NCEP ATP III, the IDF and the Harmonizing definitions respectively. The prevalence of hyperuricemia in subjects with MetS, for all three MetS definitions, was similar: 20.0%, 19.9% and 19.1% respectively. There was a graded increase in the prevalence of MetS among subjects with increasing levels of uric acid. The increasing trend persisted after stratifying for age and gender and after multivariate analysis (P for trend < 0.001).

Conclusions: This large cohort shows a high prevalence of MetS in Israel, but is still lower than the prevalence in western countries. Hyperuricemia is common in those subjects and might be considered a potential clinical parameter in the definition of MetS.
