title: Assessment of two different diagnostic guidelines criteria (National Cholesterol Education Adult Treatment Panel III [ATP III] and International Diabetes Federation [IDF]) for the evaluation of metabolic syndrome remission in a longitudinal cohort of patients undergoing Roux-en-Y gastric bypass.
abstract: BACKGROUND
  Bariatric surgery has proven to provide durable weight loss and control of comorbid conditions, including the metabolic syndrome (MS). Existing definitions of MS have caused substantial confusion regarding their concordance for identifying the same individuals. The aim of this study was to assess the value of 2 different diagnostic guidelines criteria (National Cholesterol Education Adult Treatment Panel III [ATP III] and International Diabetes Federation [IDF]) for the evaluation of remission of MS after Roux-en-Y gastric bypass (RYGB).
  
  
  METHODS
  A cohort of 381 patients who underwent a primary RYGB, satisfied the criteria for MS, and had at least o1 postoperative visit were selected. Weight loss and MS remission were analyzed 6 and 12 months after surgery by ATP III and IDF criteria.
  
  
  RESULTS
  Before surgery, 381 (48.9%) and 354 (45.4%) patients fulfilled the criteria for MS according to the ATP III and IDF, respectively. According to the ATP III definition, remission of MS after bariatric surgery occurred in 209 of 239 (87.4%) and 98/102 (96.1%) patients at 6 and 12 months, respectively. According to the IDF definition, this occurred in 180 of 232 (77.6%) and 54 of 64 (84.4%) at the same time periods. On the basis of different percentage of excess body weight loss cut-off values, the area under the curve in receiver operating characteristic analysis at 12 months was slightly better for ATP III (0.77) than IDF criteria (0.68) for remission of MS.
  
  
  CONCLUSIONS
  With the use of the IDF definition, the remission rate of MS was 10% more rigorous than with use of the ATP-III criteria. This feature is attributable to a greater discrimination of patients with high blood pressure, glycemia, and dyslipidemia. The IDF criteria seem more accurate to evaluate MS remission.
