Abstract

BACKGROUND:

Laparoscopic Roux-en-Y gastric bypass (LRYGB) is effective in reversing the metabolic syndrome (MS) in up to 90% of patients.

OBJECTIVES:

The aim of this study was to determine predictors of MS persistence 1 year after LRYGB.

SETTING:

University Hospital, France.

METHODS:

Ninety-one patients with a mean age of 44.4 years and a mean body mass index (BMI) of 43.1 kg/m² meeting the criteria for MS were enrolled in this prospective study. Anthropometric, metabolic, and inflammatory biological parameters were assessed before and 1 year after LRYGB. Patients were divided into 2 groups according to the persistence (MS nonresponders) or resolution of MS (MS responders) 1 year after LRYGB and a comparison was performed at baseline and 1 year after surgery.

RESULTS:

Sixty-nine patients (75.8%) underwent remission, while 22 (24.2%) showed persistence of MS 1 year after LRYGB. At baseline the MS nonresponders group presented significantly higher values of fasting plasma glucose (7.8 versus 5.3 mmol/L, P = .004), glycosylated hemoglobin (HbA1c, 7.3% versus 5.9%, P = .0004), triglycerides (TG, 2.37 versus 1.33 mmol/L, P = .006), and homeostasis model assessment of insulin resistance (HOMA-IR, 442.5 versus 256, P = .006). The rate of diabetes was significantly higher in this group (68.2% versus 36.8%, P = .0086), as well as the number of MS components per patient. One year after LRYGB, the MS nonresponders showed a significantly lower excess BMI lost (EBMIL) (56.1% versus 82.4%, P = .00008). On multivariate analysis, baseline levels of TG, glucose metabolism markers and EBMIL were associated with the persistence of MS.

CONCLUSION:

Baseline levels of TG, plasma fasting glucose, and HbA1c, as well as history of type 2 diabetes and EBMIL, represent predictors of MS persistence 1 year after LRYGB.
