Nonalcoholic fatty liver disease: implications for endocrinologists and cardiologists

Type 2 diabetes mellitus is not just a risk factor but a progression factor for a plethora of multi-organ complications, including the liver and the vascular system. The profibrogenic-inflammatory liver disease nonalcoholic steatohepatitis affects patient's mortality and overall cardiovascular and liver-related complications. There is an evident overlap between these diseases; therefore, there are important implications for endocrinologists, cardiologists, and hepatologists when treating these patients. In addition, as newly approved nonalcoholic steatohepatitis pharmacotherapy is expected to be available early this year, clinicians need to be able to identify patients with type 2 diabetes mellitus that are at risk of advanced liver fibrosis to establish adequate and efficient management plans to limit or avoid cardiovascular or liver-related complications. In this review, we summarize the current knowledge in the nonalcoholic steatohepatitis field with potential value for clinicians focusing on the implications of the overlap between type 2 diabetes mellitus, cardiovascular disease, and nonalcoholic steatohepatitis, the available diagnostic tools for risk stratification, management pathways, and nonalcoholic steatohepatitis pharmacotherapy, including antidiabetic and cardiovascular drugs that may be beneficial or detrimental to their patients.
