Background
There are multiple criteria to define remission of type 2 diabetes (DM2) after bariatric surgery but there is not a specific one widely accepted. Our objectives were to compare diagnostic criteria for DM2 remission after bariatric surgery: Criteria from Spanish scientific associations (SEEN/SEEDO/SED) and from the American Diabetes Association (ADA). We also aim to analyse the degree of correlation between these sets of criteria.
Methods
Retrospective observational study in 127 patients undergoing bariatric surgery in a single centre (Hospital Universitario Reina Sofía, Córdoba, Spain) between January 2001 and December 2009. We analysed DM2 remission following bariatric surgery comparing DM2 diagnostic criteria approved by Spanish scientific associations and ADA criteria.
Results
In total, 62.2% of patients were women; mean age was 47.1 years. Following surgery, 52% achieved complete remission according to ADA criteria, and 63.8% following the criteria approved by Spanish associations (p = 0.001);18.9 and 8.7%, respectively, showed partial remission (p = 0.007), and 29.1 and 27.6% no remission, according to the criteria approved by each association (p = 0.003). There was good correlation between both sets of criteria (Rho 0.781; p < 0.001).
Conclusions
In our series, using more stringent criteria for defining DM2 remission (ADA criteria) results in a lower rate of remission, although we found a a high degree of correlation between both sets of criteria.
