## Abstract

PROJECT SUMMARY
 Youth-onset type 2 diabetes (T2D) leads to early dependence on exogenous insulin and progression of T2D
co-morbidities, including dyslipidemia, hypertension, non-alcoholic fatty liver disease and diabetic kidney dis-
ease. The pathophysiology of T2D in youth differs considerably from adults and current treatment approaches
are inadequate for youth. Thus, exploration of innovative approaches to reduce co-morbidities is critical. Meta-
bolic bariatric surgery (MBS) significantly improves multiple outcomes in adults with T2D. Initial small, uncon-
trolled studies of Roux-en-Y gastric bypass also suggest beneficial effects in youth with T2D, but definitive
studies and understanding of mechanisms in youth-onset T2D are lacking, especially with the now more com-
mon form of MBS, vertical sleeve gastrectomy (VSG). Our long-term goal is to improve the treatment of youth-
onset T2D to reduce morbidity and mortality. Our central hypothesis is that VSG will be more effective in reduc-
ing glycemia and comorbidities than the best currently available medical treatment: advanced medical therapy
(AMT), via pancreatic, enterohepatic and/or metabolic changes. To test this hypothesis, we will enroll 90 ado-
lescents with T2D across two sites and compare the effects of VSG vs. AMT on glycemic control and T2D-as-
sociated comorbidities, as well as underlying mechanisms. Our sites have collaborative pediatric medical and
surgical expertise, including use of non-invasive metabolic measures in MBS and T2D and collectively have a
large, diverse adolescent T2D cohort, making us uniquely positioned to accomplish these aims. Our rationale
is that 1) there is a critical need to determine the impact of VSG over AMT in youth-onset T2D, and 2) im-
proved knowledge of the mechanisms underlying the impact of MBS will direct future non-surgical approaches
to mimic MBS less invasively. Aim 1 will evaluate the effects of VSG vs. AMT on glycemic control and T2D-
associated co-morbidities. We hypothesize that a higher proportion of youth with T2D receiving VSG vs. AMT
will achieve the primary endpoint of HbA1c <6% with higher rates of remission (lower incidence) of comorbidi-
ties at 1 and 2 years. We will also explore the impact of T2D duration, BMI, sex and initial HbA1c on the pri-
mary outcome. Aim 2 will elucidate mechanisms by which VSG & AMT influence pancreatic islet cell function,
enterohepatic metabolism and tissue-specific insulin sensitivity, and their contributions to glycemic control in
youth with T2D. We hypothesize that the primary outcome of β-cell function will improve in T2D youth undergo-
ing VSG vs. AMT at 1 and 2 years. Secondary endpoints include whole-body IR, tissue-specific IR, incretin re-
sponse and α-cell function to understand mechanisms underlying improvements. These results will determine
whether MBS is more effective than AMT in promoting glycemic control and reducing co-morbidities in youth-
onset T2D, an outcome that would dramatica...
