Patients with pre-transplantation type 2 diabetes (T2D) and new-onset diabetes post liver transplantation (NODAT) are managed with multiple doses of subcutaneous insulin (MSI) following liver transplantation. As these patients receive oral glucocorticoids (mostly prednisolone) and immunosuppressants, which elevate blood glucose levels, multiple doses of insulin are usually required. After 2-3 months, when steroid doses are tapered and doses of immunosuppressants stabilize, insulin requirements subside and several oral hypoglycemic agents are initiated, such as metformin and sitagliptin. However, these agents are prescribed off-label as the data regarding the safety and efficacy of these agents in patients with liver transplantation are scarce. Furthermore, several patients with liver transplantation develop fatty liver (liver steatosis) several months after transplantation, which is a risk factor for liver dysfunction. SGLT-2 inhibitors are reported to have favorable effect on liver fat accumulation in patients with T2D. However, the effect of SGLT-2 inhibitor on liver fat accumulation after liver transplantation has not been evaluated. Chronic liver disease is associated with changes in body composition, especially increase in visceral fat and decrease in skeletal muscle mass. Data regarding the changes in body composition following liver transplantation are scarce. In this RCT, Investigators aim to evaluate the effect of dapagliflozin vs sitagliptin on liver fat accumulation; body composition variables; and safety and efficacy of these oral hypoglycemic agents in patients with diabetes and liver transplantation
