In this session, Jeremy Davis, ACNP from Shreveport, Louisiana, breaks down a practical, step-by-step approach to evaluating abnormal liver chemistries. Using a real patient case, he reviews how to interpret ALT, AST, ALP, bilirubin, MCV, and GGT patterns; when to suspect hepatocellular, cholestatic, or mixed injury; and how to build an efficient differential using history, medications, alcohol assessment, and key labs (viral hepatitis panel, autoimmune markers, iron studies, Wilson disease testing, alpha-1 antitrypsin phenotype). He also highlights the role of ultrasound, MRCP, non-invasive fibrosis tests (FIB-4, ELF, VCTE), and when biopsy is needed. A practical, clinic-ready guide for APPs and clinicians assessing elevated liver enzymes and differentiating MASLD, alcohol-related disease, DILI, and other common etiologies.

Webcast: MASLD vs MetALD With Patrick Horne
September 2025
In this case-based session from the GHAPP MASLD Community Network, Patrick Horne, NP explains how to differentiate metabolic dysfunction–associated steatotic liver disease (MASLD) from metabolic dysfunction plus alcohol-associated liver disease (MetALD). Through the story of a 52-year-old patient with F3 fibrosis and severe steatosis, he reviews the modern SLD framework, metabolic risk factors (e.g., BMI, PCOS, hypertension, hyperlipidemia), and how alcohol intake interacts with insulin resistance, the gut microbiome, and hepatic lipid handling to accelerate inflammation and fibrosis. Patrick demonstrates practical tools—clear “standard drink” counseling, thorough history, AUDIT-C screening, and objective biomarkers like PEth—to uncover under-reported alcohol use and classify patients on the MASLD–MetALD–ALD spectrum. Management takeaways include Mediterranean-style nutrition, exercise and weight-loss targets, consideration of pharmacologic options in advanced fibrosis, firm guidance on alcohol cessation, and nuanced discussion of HCC surveillance in F3 disease. Ideal for APPs and hepatology clinicians, this talk delivers actionable algorithms, definitions, and trial-readiness considerations to standardize MetALD assessment and improve outcomes in steatotic liver disease.

Webcast: Lifestyle Management With Becky Klemme
September 2025
In this educational session, Becky Klemme, NP from Sioux Falls, South Dakota, shares over a decade of hepatology experience to highlight lifestyle management for patients with Metabolic Dysfunction–Associated Steatotic Liver Disease (MASLD). Formerly known as NAFLD, MASLD is now the most common chronic liver disease worldwide, closely linked to obesity, type 2 diabetes, hypertension, and cardiovascular disease. Through a detailed patient case, Becky explains how to evaluate MASLD using labs, imaging, and non-invasive tests like FIB-4 and FibroScan, and how to distinguish between simple steatosis, steatohepatitis (MASH), and advanced fibrosis. She outlines practical strategies for dietary changes, exercise, weight loss goals, and metabolic risk reduction—all while keeping patient-centered, culturally sensitive care in mind. Viewers will also learn about the pathogenesis of MASLD and MASH, the role of genetics and lifestyle, and evidence-based approaches such as the Mediterranean diet, structured physical activity, behavioral counseling, and the 5A framework for patient engagement. With obesity and diabetes on the rise, early recognition and proactive lifestyle intervention are essential to preventing progression to cirrhosis, liver failure, or hepatocellular carcinoma (HCC). If you are a hepatology provider, APP, or clinician managing patients with fatty liver disease, this session offers actionable insights and patient care strategies you can use in practice.

Webcast: MASLD Pharmacotherapy With April Morris
August 2025
Join April Morris, NP, a hepatology and endocrinology nurse practitioner, for a comprehensive review of MASLD pharmacotherapy as part of the GHAPP MASLD Community Network. This expert-led session outlines a three-pronged strategy for managing Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) and MASH, focusing on obesity reduction, cardiometabolic risk control, and liver-directed treatment. April walks through first-line lifestyle approaches, highlights key pharmacologic agents like GLP-1 receptor agonists, and explains their mechanisms and clinical relevance—including the groundbreaking data from the semaglutide trials showing resolution of MASH and improvement in liver fibrosis. The session also reviews the role and limitations of vitamin E and pioglitazone, emphasizing their risks in patients with diabetes or cardiovascular disease. The spotlight then shifts to resmetirom (Rezdiffra), a thyroid hormone receptor beta agonist FDA-approved for adults with non-cirrhotic NASH and moderate-to-advanced fibrosis (F2–F3). April explains the MAESTRO-NASH trial endpoints, clinical efficacy, common side effects, and appropriate patient selection. Learn how resmetirom improves fatty acid oxidation, reduces hepatic fat and fibrosis, and the key drug–drug interactions and statin dose considerations to manage during treatment. The discussion concludes with practical tips for monitoring, non-invasive staging (FibroScan, ELF, MRI-PDFF), and the evolving guidance on treatment duration, safety labs, and insurance barriers. This session is essential for clinicians navigating the growing landscape of therapeutic options in MASLD/MASH care.

Webcast: MASLD vs MetALD With Lavinia Iordache
September 2025
In this MASLD Community Network session, Lavinia Iordache, PA-C, clarifies the new SLD nomenclature and the distinctions between MASLD and MetALD, then walks through a real-world case (Ashley, 52) to show how to quantify alcohol intake, recognize cardiometabolic risk factors, and stage disease using non-invasive tests (FIB-4, FibroScan/VCTE with CAP, ELF). She explains how even “moderate” alcohol can accelerate fibrosis when metabolic risks are present, why PEth biomarker testing helps uncover under-reported use, and how to triage patients who land in the F3–F4 range.
