Clinical Deep Dive: Unlocking the Treatment Potential of Rezdiffra

March 2025

This educational discussion dives into Rezdiffra, the first and only FDA-approved therapy for non-cirrhotic metabolic-associated steatohepatitis (MASH) with moderate to advanced fibrosis. The talk provides a clinical deep dive into the progression of MASH and fibrosis, highlighting the risks of untreated disease and the importance of early intervention. A key focus is the thyroid hormone receptor beta mechanism, explaining how Rezdiffra directly targets liver-specific pathways to reduce hepatic fat accumulation and fibrosis. Additionally, the discussion covers the rigorous FDA approval process and dual efficacy endpoints, detailing how Rezdiffra achieved significant fibrosis improvement and steatohepatitis resolution in the MAESTRO-NASH trial. The session also provides practical insights into patient access, prescribing considerations, and managing common side effects. With over 2,000 patients studied, Rezdiffra has demonstrated a strong safety profile and offers a once-daily oral treatment option that represents a major advancement in MASH management. This discussion is essential for gastroenterologists, hepatologists, and endocrinologists managing patients with MASH, as well as primary care providers and cardiologists who play a role in identifying at-risk individuals. If you are a healthcare professional looking to stay updated on the latest MASH research and treatment strategies, this session provides the insights you need.

Liver Model Overview

July 2025

Join Alison Moe, PA-C with United Digestive, as she walks through a hands-on demonstration using a life-sized liver model to help patients better understand fibrosis and liver disease progression. In this engaging and practical overview, Allison explains how different stages of liver fibrosis—from normal liver to cirrhosis and hepatocellular carcinoma—can be felt and visualized using a segmented anatomical model. She shares how this tool enhances patient education during discussions about non-invasive liver testing, such as FibroScan, CAP scores, FIB-4, ELF testing, and more. Designed to support visual learners and improve comprehension of disease state, this video is a valuable resource for clinicians and patients navigating the complexities of metabolic-associated fatty liver disease (MASLD) and its progression to MASH. Learn how tactile and visual teaching aids can bridge the gap between diagnostics and patient understanding in hepatology care.

Differentiating Between F3 and F4

July 2025

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.

Addressing Health Disparities: Equity Considerations in MASH/MASLD Care

July 2025

In this episode, Patrick Horne, NP at the University of Florida (UF Health), explores the impact of health disparities and socioeconomic inequality on the diagnosis and management of MASH (metabolic-associated steatohepatitis) and MASLD (metabolic dysfunction-associated steatotic liver disease). With a focus on rural and underserved populations, Patrick discusses how limited access to quality healthcare, healthy food, exercise options, and non-invasive testing (NITs) like FibroScan or MRI elastography can delay diagnosis and worsen outcomes. He shares practical, empathetic strategies for individualizing care, such as using accessible tools like FIB-4 or APRI, promoting low-cost physical activity like walking or swimming, and providing culturally sensitive nutrition advice tailored to financial and geographic realities. Patrick emphasizes the provider’s role as a patient advocate and coach, helping patients navigate barriers and create sustainable lifestyle modifications. This episode offers key insights for clinicians working to close gaps in care and promote equity in liver disease management.
