Podcast: Viral Hepatitis and MASH/MASLD: Understanding the Connection
June 2025
In this episode, Patrick Horne, NP from the University of Florida, explores the important connection between viral hepatitis and MASLD/MASH (Metabolic Dysfunction–Associated Steatotic Liver Disease/Steatohepatitis). While patients may present with a presumed diagnosis of MASLD or MASH, Patrick emphasizes the critical need to rule out coexisting liver diseases such as hepatitis B and C. The presence of both metabolic and viral liver diseases can significantly accelerate liver inflammation, fibrosis progression, and ultimately cirrhosis—a concept he explains using the “two-hit” or even “three-hit” theory. Patrick walks through the recommended screening protocols, including one-time HCV testing for all adults over 18 and complete HBV panels to assess for immunity, past exposure, and chronic infection. He stresses that treating viral hepatitis—especially with today's highly effective antivirals—can and should occur alongside lifestyle modification strategies for MASLD/MASH. He also discusses how liver stiffness measurements can be skewed by active inflammation and suggests reassessing fibrosis after treating viral hepatitis. This episode is a must-watch for providers managing patients with liver disease, highlighting the need for a comprehensive, layered diagnostic approach.
