NCT01969968

Brief Summary

  1. 1.To study the kinetics of release after bariatric surgery of selected polluants stored in adipose tissue, looking for clinical and/or predictive factors
  2. 2.To test the hypothesis of a deleterious effect of this release on the expected improvement of insulin-resistance and on the liver inflammation.
  3. 3.To determine the level of contamination of morbidly obese patients, with or without metabolic syndrome, compared to a control, non obese population, with special attention to clinical (age, gender, reproductive history, pregnancy, nursing) and biological parameters (insulin-resistance, inflammation).

Outcome Measures

Primary Outcomes (2)

  • measurement of POPs

    Urinary and blood POPs dosage 18 months after bariatric surgery

    18 months

  • clinical and biological assessment of metabolic syndrome
