MASLD-MASH Content Featuring Christie
MASLD Pharmacotherapy With Jordan Mayberry
July 2025
Join Jordan Mayberry, MPAS, PA-C from UT Southwestern, for an insightful session from the GHAPP MASLD/MASH Community Network focused on the evolving landscape of pharmacotherapy in MASLD and MASH. This presentation explores evidence-based strategies for treating metabolic dysfunction–associated steatotic liver disease (MASLD), with an emphasis on weight loss, diabetes management, and liver-directed therapies. Jordan breaks down key data on GLP-1 receptor agonists, SGLT2 inhibitors, Vitamin E, pioglitazone, and highlights the latest clinical evidence supporting the use of Resmetirom—the first FDA-approved treatment for MASH with stage 2 or 3 fibrosis. Learn how these therapies fit into hepatology practice, including clinical considerations, side effect management, and patient selection. Stay up to date on ongoing research, treatment duration, and real-world application of these new therapies. Don’t forget to register and join the GHAPP MASLD/MASH Community Network for continued education and access to valuable resources.

Common Questions from Community GI About MASH
July 2025
In this insightful video, Christie Morrison, a local advanced practice provider with the GHAPP MASLD/MASH Community Network, answers two of the most frequently asked questions from community GI providers: when to refer patients with MASH to a transplant center and how to evaluate liver fibrosis when FibroScan® isn’t accessible. Christy emphasizes the importance of using non-invasive testing (NITs)—including FIB-4 and ELF (Enhanced Liver Fibrosis) scores—to help identify patients with F3 fibrosis, who are at higher risk for rapid progression to cirrhosis and hepatocellular carcinoma (HCC). She encourages early referral to transplant hepatology to avoid delays in care, especially given long wait times and the value of multidisciplinary support teams at transplant centers. For clinicians without access to FibroScan, Christy shares practical alternatives such as ordering reflex testing to ELF via major labs and leveraging easy-to-use digital tools like MDCalc for FIB-4 calculation. This episode is a valuable resource for GI providers looking to optimize liver care pathways and prevent late-stage complications in MASLD and MASH patients.

Approved Medication for MASH/NASH
January 2025
This video provides detailed guidance on selecting and monitoring patients for emerging therapies targeting advanced fibrosis (F2-F3) in NASH. Key topics include contraindications for patients with cirrhosis, considerations for concomitant medications, and dose adjustments for statins. The video outlines ideal candidates based on specific thresholds for VCTE, MRE, ELF scores, and other non-invasive tests while emphasizing the importance of ruling out portal hypertension and other liver diseases. It also reviews a stepwise monitoring approach, focusing on tolerability at three months and efficacy assessments at six and twelve months, with an emphasis on histologic and non-invasive test improvements.

Comparing F3 and F4 Fibrosis With Christie Morrison
August 2025
In this expert-led session, Christie Morrison, NP, shares a comprehensive case-based discussion on comparing F3 vs F4 fibrosis in patients with MASH (Metabolic Dysfunction-Associated Steatohepatitis). Through the lens of two real-world clinical scenarios, Christie breaks down the nuanced differences in non-invasive diagnostic tools such as FIB-4, ELF scores, and FibroScan KPA readings, while guiding providers on how to stratify risk, monitor disease progression, and tailor interventions appropriately. Viewers will learn how elevated liver enzymes, declining platelet counts, and steatosis scores influence decision-making in patients with metabolic comorbidities like type 2 diabetes, hypertension, and hyperlipidemia. The session emphasizes evidence-based lifestyle and pharmacologic strategies, including the potential role of resmetirom (Rezdiffra) in F3 fibrosis and why it’s contraindicated in advanced cirrhosis. Learn when to initiate HCC surveillance, how to interpret borderline labs, and the importance of integrating GLP-1s, dietitian referrals, and cardiometabolic care to slow or reverse fibrosis progression. Whether you’re managing intermediate or advanced fibrosis, this educational session provides invaluable insights into optimal MASH care pathways and staging techniques.

NITs: A Practical Overview: Navigating the Basics
July 2025
In this episode, Christie Morrison breaks down the fundamentals of non-invasive testing (NITs) for evaluating patients with fatty liver disease, including MASLD and MASH. She explains the key differences between steatosis (MASLD) and steatohepatitis (MASH), highlighting how non-invasive tests can replace liver biopsy for staging fibrosis. Christy reviews common tools like FIB-4, NAFLD fibrosis score, Enhanced Liver Fibrosis (ELF) score, transient elastography (FibroScan), and MR elastography, and outlines how to choose the right test based on patient factors such as co-morbidities, geography, access to labs, and imaging availability. The episode also emphasizes the importance of fibrosis risk stratification, interpreting FIB-4 cutoffs, and monitoring liver stiffness or ELF scores after initiating lifestyle or pharmacologic treatment—including newer therapies like resmetirom. This is a must-watch for APPs, GI clinicians, and primary care providers seeking to improve care pathways and outcomes in patients with metabolic liver disease through practical, accessible strategies for fibrosis detection and management.
