This practice recommendation serves as an update to the 2023 AASLD Practice Guidance on the clinical assessment and management of nonalcoholic fatty liver disease (NAFLD), now known as metabolic dysfunction–associated steatotic liver disease (MASLD), and provides implementable guidance on patient selection for treatment, consideration of comorbidities, and monitoring of treatment safety and efficacy of semaglutide. FDA-indication and Practice Recommendation: The Wegovy formulation, whose main ingredient is semaglutide, received accelerated FDA approval in August 2025 for treating MASH with moderate-to-advanced fibrosis (consistent with stages F2–F3 fibrosis), based on interim results of the phase 3 ESSENCE trial where 72 weeks of 2.4 mg/week subcutaneous injection resulted in achievement of both primary histologic endpoints: (1) resolution of MASH without worsening of fibrosis (62.9% vs. 34.3% placebo, p <0.001) and (2) ≥1 stage reduction in liver fibrosis without worsening of MASH (36.8% vs. 22.4% placebo, p <0.001); final approval awaits long-term outcomes. Patient Selection: Candidates should have MASH with stage 2–3 fibrosis, identified using non-invasive tests (NITs) such as VCTE (8–15 kPa), MRE (3.1–4.4 kPa), or ELF (9.2–10.5), rather than liver biopsy, which is impractical and unnecessary for most patients. In those with VCTE (15–20 kPa), MRE (4.4–5 kPa), or ELF (10.5–11.3), an individualized decision to treat should be based on exclusion of cirrhosis with another confirmatory NIT, or cross-sectional imaging excluding nodular-appearing liver contour and signs of portal hypertension, or a platelet count of <150,000/mm 3 . While semaglutide is not approved to treat patients with MASH cirrhosis (VCTE >20 kPa, MRE>5.0 kPa, ELF>11.3, and/or evidence of portal hypertension), those with compensated cirrhosis who are receiving semaglutide for another FDA-approved indication should be monitored carefully. Monitoring and Safety: Semaglutide showed a favorable hepatic safety profile in the ESSENCE trial, with no discontinuations due to liver enzyme elevations. Routine hepatic panels are recommended only as clinically indicated. The most common adverse events were gastrointestinal (nausea, diarrhea, constipation, vomiting), generally mild and transient; patient education and dose titration help improve tolerance. Clinicians should monitor for rare but serious risks, including acute kidney injury (from dehydration), symptomatic gallbladder disease, pancreatitis, thyroid C-cell tumors, retinopathy progression, and lean mass loss. Treatment Response and Concomitant Therapy: Lifestyle modification remains the cornerstone of MASLD/MASH management alongside semaglutide. Combination use of resmetirom with semaglutide 2.4mg/week has not been studied. While no NITs reliably predict histologic response at the individual patient level, reductions from baseline to 72 weeks of treatment suggest significant improvement in MASH resolution (ALT ≥17 U/L or ≥20%) and fibrosis improvement (VCTE LSM ≥30%; MRE LSM ≥20%; ELF ≥0.5). Non-response may be suspected if ALT or NITs worsen. The benefit is uncertain if a suboptimal response occurs, and may require an individualized approach and further follow-up.

Because Model for End‐Stage Liver Disease (MELD) scores at the time of liver transplantation (LT) increase nationwide, patients are at an increased risk for delisting by becoming too sick or dying while awaiting transplantation. We quantified the risk and defined the predictors of delisting or death in patients with cirrhosis hospitalized with an infection. North American Consortium for the Study of End‐Stage Liver Disease (NACSELD) is a 15‐center consortium of tertiary‐care hepatology centers that prospectively enroll and collect data on infected patients with cirrhosis. Of the 413 patients evaluated, 136 were listed for LT. The listed patients' median age was 55.18 years, 58% were male, and 47% were hepatitis C virus infected, with a mean MELD score of 2303. At 6‐month follow‐up, 42% (57/136) of patients were delisted/died, 35% (47/136) underwent transplantation, and 24% (32/136) remained listed for transplant. The frequency and types of infection were similar among all 3 groups. MELD scores were highest in those who were delisted/died and were lowest in those remaining listed (25.07, 24.26, 17.59, respectively; P < 0.001). Those who were delisted or died, rather than those who underwent transplantation or were awaiting transplantation, had the highest proportion of 3 or 4 organ failures at hospitalization versus those transplanted or those continuing to await LT (38%, 11%, and 3%, respectively; P = 0.004). For those who were delisted or died, underwent transplantation, or were awaiting transplantation, organ failures were dominated by respiratory (41%, 17%, and 3%, respectively; P < 0.001) and circulatory failures (42%, 16%, and 3%, respectively; P < 0.001). LT‐listed patients with end‐stage liver disease and infection have a 42% risk of delisting/death within a 6‐month period following an admission. The number of organ failures was highly predictive of the risk for delisting/death. Strategies focusing on prevention of infections and extrahepatic organ failure in listed patients with cirrhosis are required. Liver Transpl 21:881‐888, 2015. © 2015 AASLD.
