Nonalcoholic steatohepatitis (NASH), part of the nonalcoholic fatty liver disease (NAFLD) spectrum, is characterized by steatosis, lobular inflammation, hepatocyte ballooning, and varying degrees of fibrosis.1 Both obesity and diabetes play large roles in development and progression of NAFLD and NASH, and the growing prevalence of NAFLD and NASH parallel the rise in obesity and diabetes.2 In addition to obesity and diabetes, multiple comorbidities occur with NASH; the 2 comorbidities that are strongly tied to mortality are cardiovascular disease and malignancy.3,4 Liver biopsy, often impractical or unfeasible, is the gold standard for diagnosis.5 Recently, noninvasive modalities, particularly imaging, have been used as substitutes to identify patients at risk for disease progression; there are, however, deficits in knowledge and access to some noninvasive modalities. Though there is no US Food and Drug Administration (FDA)-approved treatment for NASH, fibrosis, along with other histopathologic markers of NASH, can be improved through lifestyle modification or off-label use of therapies.5 Recent clinical trial data have been encouraging, but management of patients with NASH still proves difficult, necessitating education about diagnosis and management.

This activity presents a review of the pathophysiology of NASH, noninvasive and invasive diagnostic methods, existing management options, and investigational targeted therapies through innovative infographic panels, which allow the learner to, at his or her pace, delve into each concept presented in the multiple layers of the panel.
Upon completion of this activity, participants will be better able to do the following:
- Identify patients with or at risk for the development of nonalcoholic steatohepatitis (NASH) using current epidemiologic and demographic data
- Select appropriate invasive biopsy and/or noninvasive assessment modalities for diagnosing, staging, and monitoring NASH
- Describe late-stage emerging NASH therapies in terms of mechanisms of action, relationships with disease pathophysiology and fibrosis progression, and the most recent efficacy and safety clinical data
