Do Bariatric Surgery-Related Type 2 Diabetes Remission Predictors Add Clinical Value? A Study on Asian Indian Obese Diabetics.

Background: Bariatric surgery has emerged to be the most effective treatment strategy for the treatment of obesity and type 2 diabetes mellitus (T2DM) achieving high remission rates. Many factors have been evaluated with a potential to predict the improvement of glycemic control following bariatric procedures. This study aims to study the various predictive factors for T2DM and the ABCD score in obese diabetic patients undergoing bariatric surgery in a South Indian population. Methods: A total of 53 obese patients (BMI > 30 k/m) with T2DM who underwent laparoscopic sleeve gastrectomy (LSG) and laparoscopic gastric bypass (LGB) from March 2014 to March 2015 were selected for the study. The patients were followed up to study the effects of various predictors of T2DM remission at 1 year. Results: Out of the 53 patients, 35 (66%) underwent LSG and 18 (34%) underwent LGB. Patients (81.1%) had T2DM remission. Mean HbA1c values decreased from 8.07 ± 1.98 to 6.0 ± 0.71. Only higher pre-operative body weight ( p = 0.04) and lower HbA1c level ( p = 0.04) were significantly associated with T2DM remission. Higher absolute weight loss ( p = 0.03) after surgery was also significantly associated with T2DM remission. ABCD score was not significantly associated with T2DM remission although patients with ABCD score higher than 7 demonstrated 100% remission rate. Conclusion: Among all the factors, only higher pre-operative weight and better glycaemic control along with better post-operative weight loss were significantly associated with the remission of T2DM. Although not significantly associated with remission of T2DM, higher ABCD scores had higher likelihood of remission. [ABSTRACT FROM AUTHOR]
