title: Biochemical correlates of bariatric-responsive diabetes.
abstract: OBJECTIVE
  In a prospective observational cohort study, the biochemical profile of bariatrically managed diabetes was documented, aiming to assess its association with clinical outcome.
  
  
  METHODS
  The population (n = 82; age, 50.7 +/- 10.3 years; 92.7% women; followed up for 93 +/- 34 months) was stratified as responsive diabetes (Group I) (36.6%, 30 of 82) and controls without diabetes (Group II) (57.3%, 47 of 82). A few refractory subjects were identified in this cohort (Group III [refractory diabetes], 6.3%, five of 82). Nonbariatric overweight and obese diabetes subjects with similar follow-up (n = 21) were documented as well. Main outcome measures were diabetes regression, body mass índex (BMI), glucose, glycosylated hemoglobin A1c (HbA1c), serum lipids, and white blood cell count (WBC) count.
  
  
  RESULTS
  Preoperative BMI was somewhat discrepant among operated groups but leveled off from 2 years on. Baseline WBC count, total cholesterol, low-density lipoprotein-cholesterol, blood glucose, and HbA1c were higher in responsive subjects, but a downward shift occurred, without differences regarding controls, in the subsequent period. Conservatively managed diabetes displayed favorable changes of some lipid fractions, but not glucose, HbA1c, total cholesterol, or WBC count.
  
  
  CONCLUSIONS
  Diabetes regression rate was 94.3% at 5 years and 84.7% at around 8 years. In responsive patients, both BMI and biochemical indices normalized in the first 2 years and followed a stable path thereafter. Nonoperative treatment was unable to reduce HbA1c, glucose, or WBC count, and HbA1c was a clear prognostic marker of persistent disease in surgical cases. Further studies emphasizing the metabolic and inflammatory signature of obesity-related diabetes are worthwhile.
