Join Erin Tanner, NP from Gastro Health in Birmingham, Alabama, for a practical and in-depth exploration of how to differentiate and manage patients with F3 versus F4 fibrosis in the setting of MASLD (Metabolic Dysfunction-Associated Steatotic Liver Disease) and MASH. This session, part of the MASLD & MASH Community Network, features two detailed case studies—Sam A and Sam B—who share identical comorbidities but diverge in fibrosis stage, illustrating how non-invasive testing (NITs) can guide diagnosis and treatment. Erin walks through the clinical application of tools like FIB-4, FibroScan (VCTE), ELF test, and CAP score, emphasizing the importance of interpreting lab and imaging results in context. The discussion covers key decision points, including when to initiate pharmacologic therapy like resmetirom (Rezdiffra), how to determine eligibility for HCC surveillance, and when to consider liver biopsy. She also addresses common challenges in community GI settings, such as incidental fatty liver findings, elevated ferritin levels, and the limitations of FIB-4 in older or diabetic patients. Whether you're in hepatology, gastroenterology, or primary care, this talk offers actionable insights on fibrosis staging, lifestyle counseling, and long-term monitoring in patients with MASLD and MASH.
