MASLD/MASH Global Consensus Recommendations Address Guideline Discordance
FROM GASTROENTEROLOGY
These recommendations aim to boost guideline adherence and disease awareness, which have lagged despite a surge of national and international guidance in recent years, lead author Zobair M. Younossi, MD, of the Global NASH/MASH Council, Washington, DC, and colleagues, reported.
“Although these documents are similar in many ways, there are important differences in their recommendations, which have created some confusion within the field,” the panel wrote in Gastroenterology. “Areas of discordance among guidelines can be partly responsible for their low rate of implementation and the suboptimal awareness about this liver disease. Furthermore, these guidelines can be long and complex, making it challenging for busy clinicians to access the appropriate information quickly and efficiently.”
To address these gaps, more than 40 experts from around the world collaborated on the consensus project. The team reviewed 61 eligible documents published between 2018 and January 2025. Each guideline was evaluated across eight domains: epidemiology; screening; risk stratification using noninvasive tests (NITs); lifestyle management; treatment with existing medications; treatment with future medications; hepatocellular carcinoma (HCC) and preventive guidance; and pregnancy and pediatric populations.
Areas of discordance were advanced to a Delphi process using iterative online surveys, with a supermajority threshold of 67% required for acceptance. Four Delphi rounds were conducted, and by the end, all statements had achieved more than 90% agreement. The final recommendations were then summarized into practical algorithms for clinical use.
The results cover the full spectrum of MASLD care. For screening and diagnosis, experts agreed that individuals with type 2 diabetes, obesity plus cardiometabolic risk factors, or persistently elevated aminotransferases should be considered high risk. Alcohol thresholds were standardized, clarifying when to classify disease as MASLD, alcohol-related liver disease, or the hybrid “Met-ALD.”
For risk stratification, the panel endorsed a two-step algorithm beginning with the Fibrosis-4 (FIB-4) index, followed by vibration-controlled transient elastography (VCTE) or other NITs in patients above the threshold. This approach, the authors noted, was designed to be feasible in both primary care and specialty settings.
Lifestyle intervention remains the cornerstone of treatment, with weight-loss goals of 5% to reduce steatosis, 7%–10% to reduce inflammation, and at least 10% to improve fibrosis. To this end, the panel recommended a Mediterranean-style diet, increased physical activity, and reductions in sedentary time.
Drug therapy recommendations prioritized glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter-2 (SGLT2) inhibitors for patients with diabetes or obesity, though these were not considered MASH-specific agents. Pioglitazone was noted as an option for diabetes management but not as direct MASH therapy. The panel did not recommend vitamin E, ursodeoxycholic acid, or omega-3 fatty acids, citing insufficient evidence.
The document also provides structured guidance on resmetirom, the first FDA-approved therapy for MASH. Its use was endorsed in patients with F2–F3 fibrosis confirmed by NITs, with safety checks at 3, 6, and 12 months, and efficacy evaluation after 1 year. Treatment futility was defined as concordant worsening across two NITs.
Preventive recommendations included hepatitis A and B vaccination and HCC surveillance every 6 months in patients with cirrhosis. Surveillance in noncirrhotic MASH was left to clinician judgment, based on individualized risk factors. Special considerations were outlined for pediatric and pregnant populations, although the evidence base in these groups remains sparse.
“Further research is required to determine the effectiveness of this algorithm in raising awareness of MASLD and its treatment,” Dr. Younossi and colleagues concluded.
The study was supported by the Global NASH/MASH Council, Inova Health System, and an unrestricted educational grant from Madrigal Pharmaceuticals. The investigators disclosed relationships with Sanofi, Gilead, AstraZeneca, and others.
