Letter to Editor: Role of Pharmacotherapy in Patients With Coexisting Nonalcoholic Fatty Liver Disease and Type 2 Diabetes Mellitus.

We read with interest a recent article written by Yan et al.(1) The authors conducted a randomized trial in patients with coexisting type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver disease (NAFLD) to receive liraglutide, sitagliptin, or insulin glargine as add-on to metformin. The authors observed glycemic control and a reduction in body weight, intrahepatic lipid, and visceral adipose tissue in patients who received liraglutide or sitagliptin and then reported these add-on therapies to be novel pharmacotherapeutic therapies in patients with NAFLD and T2DM. However, the clinical meaningfulness of these pharmacologic treatments has not been conclusively established, especially since histopathology was not used to diagnose and determine the severity of NAFLD in that study.
