In this comprehensive discussion, HoChong Gilles, a nurse practitioner with 25 years of hepatology experience at the Richmond VA Medical Center, explores the critical importance of accurately distinguishing between F3 (advanced fibrosis) and F4 (cirrhosis) in patients with MASH (metabolic-associated steatohepatitis). While both stages carry increased risks of liver-specific and overall mortality, Gilles explains that F3 may still be reversible with lifestyle changes or pharmacotherapy, whereas F4 signals irreversible liver damage with heightened risk of complications like portal hypertension, hepatic encephalopathy, and liver cancer. Viewers will gain a deeper understanding of how non-invasive tests—like FIB-4, ELF, FibroScan, and MRE—perform in identifying fibrosis stage, including their limitations and overlaps. Gilles also outlines when to consider liver biopsy, especially in cases with discordant test results, atypical features, or clinical uncertainty. This video emphasizes how staging accuracy informs eligibility for therapies, surveillance strategies like HCC screening, and overall prognosis. Learn how to approach this nuanced distinction in clinical practice and why F3 vs. F4 isn't just semantics—it's a turning point in patient care.

Podcast: Pharmacotherapy for MASH/MASLD: An Overview
June, 2025
In this informative episode, Lindsay Yoder, PA, a hepatology expert at Indiana University, provides a comprehensive overview of current pharmacotherapy options for MASH (Metabolic Dysfunction–Associated Steatohepatitis), focusing on the first FDA-approved medication, resmetirom (brand name: Rezdiffra). Speaking directly to the MASLD/MASH Community Network, Lindsay breaks down the key histologic endpoints that led to resmetirom’s conditional approval—namely, fibrosis improvement without worsening of steatohepatitis, and MASH resolution without worsening fibrosis. She shares real-world data from clinical trials showing that resmetirom nearly doubles the rate of fibrosis improvement and triples MASH resolution compared to placebo. Lindsay also explains how the drug works: as a thyroid hormone receptor beta agonist, resmetirom improves hepatic lipid metabolism, reduces liver fat, and dampens inflammation—all key drivers of MASH progression. She outlines ideal patient criteria (stage F2–F3 fibrosis without cirrhosis), safety considerations, tolerability, potential side effects, and statin interactions. With an emphasis on combining pharmacotherapy with lifestyle changes, this episode serves as a practical guide for clinicians treating patients with MASH who qualify for advanced intervention.

Podcast: Alcohol and MASLD/MASH: Navigating the Complex Relationship
June, 2025
In this powerful and highly educational episode, Scott Springer, PA-C at Erie County Medical Center in Buffalo, NY, explores the complex and often overlooked relationship between alcohol use and metabolic dysfunction–associated steatotic liver disease (MASLD/MASH). Drawing from his dual expertise in hepatology and addiction medicine, Scott outlines the importance of accurately assessing alcohol use when diagnosing MASLD, MASH, MetALD, or ALD—emphasizing that MASLD and MASH are diagnoses of exclusion and heavily influenced by alcohol consumption thresholds. He discusses best practices for screening, including patient-centered, nonjudgmental interviewing, the use of biomarkers like PEth and urine ethyl glucuronide, and how these tools enhance accuracy and accountability in care. Scott reviews national guidelines that recommend alcohol abstinence for patients with chronic liver disease and presents data showing how even small reductions in alcohol use can significantly lower the risk of cirrhosis. He also unpacks the challenges of interpreting liver tests in patients with ongoing alcohol use, the limitations of non-invasive testing like FibroScan and FIB-4, and how alcohol may disqualify patients from emerging pharmacotherapy such as resmetirom. Finally, he highlights the promising potential of GLP-1 medications in managing both liver fibrosis and alcohol use. This episode is essential listening for hepatology providers, addiction specialists, and any clinician involved in the care of patients with coexisting liver disease and substance use disorders.

Podcast: Pharmacotherapy for MASH/MASLD: An Overview
June, 2025
In this comprehensive episode, Christina Hanson, FNP-C at South Denver GI, provides an in-depth overview of pharmacotherapy for MASLD and MASH, with a focus on the FDA-approved therapy resmetirom (brand name Rezdiffra). Drawing on over 18 years of experience in hepatology and GI care, Christina explains the histologic endpoints used in clinical trials—MASH resolution and fibrosis improvement without worsening disease—and how they guided the approval of resmetirom. She breaks down the drug’s mechanism of action as a selective thyroid hormone receptor beta (THR-β) agonist, which promotes lipid metabolism and reduces liver inflammation without systemic toxicity. Christina reviews key Phase 3 data from the MAESTRO-NASH trial, showing resmetirom’s significant impact on both MASH resolution and fibrosis regression across diverse patient populations. She also outlines criteria for appropriate patient selection (those with stage F2-F3 fibrosis), clinical monitoring strategies, and management of side effects like transient GI discomfort. Christina emphasizes the importance of baseline screening for liver disease, autoimmune conditions, thyroid function, and lipid levels before initiating therapy. She highlights best practices from the 2024 AASLD guidelines for ongoing monitoring and treatment response assessment, including ALT and liver stiffness thresholds that help determine whether to continue or discontinue therapy. This episode is a must-watch for hepatology clinicians looking to implement evidence-based, patient-centered strategies in the management of MASH.

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.
