AbstractBackground and Objectives: A third of the American adult population is currently pre-diabetic/morbidly obese and is, therefore, at an elevated risk for developing type 2 diabetes. Unfortunately, such a condition does not spare children from also developing morbid obesity, where incidence rates of childhood obesity-coupled with type 2 diabetes-are markedly elevated. Laparoscopic sleeve gastrectomy (LSG) is gradually becoming the novel benchmark in bariatric surgery for the treatment of morbid obesity and associated co-morbidities, also within pediatric cases. However, no comprehensive study has been conducted in children that emphasizes the effect of LSG on HbA1C levels within such a patient population suffering from type 2 diabetes. Aim: Since HbA1C is a major biomarker for type 2 diabetes progression, this study aimed to identify any dysregulated serum levels for this key molecular player (together with other parameters), for post-surgical monitoring of the beneficial metabolic effects of LSG surgery on type 2 diabetes amelioration/remission within pediatric patients. Materials and Methods: A total of 64 pediatric patients, ranging in age from 5 to 14 years old, were enrolled in this retrospective study. Multiple laboratory-based analyses datasets were also collected from individual study participants, including HbA1C and random blood sugar (RBS). All participating patients were designated for undergoing laparoscopic sleeve gastrectomy, as per standardized surgical protocols and each participant was followed-up for two years post-surgery. Laboratory investigations were re-performed in order to identify any major variations in clinical parameters. Results: HbA1c was significantly reduced among children, from 6.0 ± 0.8 (pre-LSG) to 5.4 ± 0.4 post-surgery, with a reduction rate of 10.9% (p = 0.001). Furthermore, RBS significantly decreased from 102.9 ± 34.0 (pre-LSG) to 87.1 ± 17.3 post- surgery, with a reduction rate of 15.4% (p = 0.036). Conclusions: This study provides further concrete evidence for the beneficial metabolic influence provided by LSG surgery on morbidly obese, childhood-aged patient populations, with effectiveness in reducing co-morbidity progress, in the form of type 2 diabetes, through the reduction in HbA1c levels within such patients post-surgery.
