Management of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD)

MASLD requires a multidisciplinary approach prioritizing lifestyle modification with weight loss targets of ≥5% for steatosis reduction, 7-10% for inflammation improvement, and ≥10% for fibrosis regression, combined with Mediterranean dietary patterns, structured exercise programs, and consideration of resmetirom for non-cirrhotic MASH with significant fibrosis (stage ≥2). 1

Disease Definition and Spectrum

MASLD is defined as hepatic steatosis in the presence of at least one cardiometabolic risk factor (abdominal obesity, type 2 diabetes/prediabetes, hypertension, elevated triglycerides, or low HDL cholesterol) with alcohol consumption <140 g/week for women and <210 g/week for men. 1 The disease spectrum progresses from isolated steatosis (MASL) through metabolic dysfunction-associated steatohepatitis (MASH, characterized by hepatocellular ballooning and lobular inflammation) to fibrosis, cirrhosis, and hepatocellular carcinoma. 1, 2

MASLD affects 30-40% of the global adult population, with prevalence reaching 60-70% in patients with type 2 diabetes and 70-80% in those with obesity. 2

Risk Stratification and Diagnosis

Case-Finding Strategy

Apply non-invasive testing in individuals with:

  • Type 2 diabetes or obesity with additional metabolic risk factors 1
  • Abnormal liver enzymes 1
  • Radiological signs of hepatic steatosis 1

Stepwise Fibrosis Assessment

Use a two-step approach: first calculate FIB-4 (Fibrosis-4 index incorporating age, AST, ALT, and platelet count), then proceed to vibration-controlled transient elastography for those with elevated scores to rule-in/rule-out advanced fibrosis. 1, 2 Advanced fibrosis is the strongest predictor of liver-related outcomes and mortality. 1

Lifestyle Modification: The Foundation of Treatment

Weight Loss Targets (Dose-Dependent Benefits)

For patients with MASLD and overweight/obesity, achieve sustained weight reduction with specific histological targets: 1

  • ≥5% weight loss: Reduces liver fat/steatosis
  • 7-10% weight loss: Improves liver inflammation and resolves steatohepatitis
  • ≥10% weight loss: Improves fibrosis

These targets are based on Level 1-2 evidence showing dose-dependent histological improvements. 1 However, long-term data demonstrating impact on clinical liver-related outcomes and mortality remain limited. 1

Dietary Interventions

Implement a Mediterranean dietary pattern as the primary dietary approach, characterized by: 1

  • High intake of vegetables, fruits (not juice), low-fat dairy, nuts, olive oil, legumes, unprocessed fish and poultry
  • Minimizing processed meat and ultra-processed foods rich in sugars and saturated fat
  • Complete avoidance of sugar-sweetened beverages

This recommendation carries Level 2 evidence with strong consensus for improving histologically or non-invasively assessed liver injury. 1 A critical caveat: while diet quality improvements show benefits on liver injury markers, there is little evidence that dietary changes alone beneficially impact clinical liver-related outcomes. 1

Physical Activity Prescription

Prescribe structured exercise programs targeting >150 minutes/week of moderate-intensity OR 75 minutes/week of vigorous-intensity physical activity, tailored to individual preference and ability. 1 This carries Level 1 evidence for reducing steatosis. 1

Important limitation: While physical activity provides well-documented cardiometabolic benefits, evidence for benefits on histological outcomes, non-invasively assessed liver damage/fibrosis, and liver-related clinical outcomes is less robust. 1

Special Population: Normal-Weight MASLD

For normal-weight adults with MASLD, diet and exercise interventions should still be recommended to reduce liver fat. 1 In MASH cirrhosis with normal weight, implement high-protein diet with late-evening snacks, particularly for sarcopenia or decompensated cirrhosis. 1

Alcohol and Smoking

Discourage alcohol consumption; complete avoidance is recommended in advanced fibrosis or cirrhosis. 1 Smoking avoidance is advised. 1 Coffee consumption has been associated with improvements in liver damage and reduced liver-related clinical outcomes in observational studies. 1

Pharmacological Therapy

MASH-Targeted Treatment: Resmetirom

For adults with non-cirrhotic MASH and significant liver fibrosis (stage ≥2), resmetirom (a thyroid hormone receptor β-selective agonist) should be considered as first-line MASH-targeted therapy if locally approved. 1, 2 This recommendation is based on Phase III registrational trial data demonstrating histological efficacy on both steatohepatitis resolution and fibrosis regression with acceptable safety and tolerability profile. 1

Resmetirom may also be considered for individuals with:

  • Advanced fibrosis (documented by biopsy or non-invasive panels) 1
  • At-risk steatohepatitis with significant fibrosis 1

Incretin-Based Therapies

Consider GLP-1 receptor agonists (semaglutide, tirzepatide) for patients with MASLD and coexisting type 2 diabetes or obesity requiring pharmacological weight loss intervention. 1, 2 Semaglutide is conditionally FDA-approved for adults with MASH and moderate to advanced fibrosis. 2 These agents provide dual benefits: weight reduction achieving the 7-10% threshold for MASH improvement and direct metabolic effects. 1

Other Metabolic Medications

Pioglitazone shows hepatic benefit based on Phase II data. 1 Treatment of cardiometabolic comorbidities with statins, aspirin, and renin-angiotensin-aldosterone modulators may modify disease progression and contribute to reduction in liver-related events. 1

What NOT to Use

Nutraceuticals cannot be recommended due to insufficient evidence of effectiveness in reducing histologically/non-invasively assessed liver damage/fibrosis and liver-related outcomes, nor evidence of safety. 1

Bariatric Surgery

Consider bariatric surgery for patients with MASLD and class II-III obesity (BMI >35 kg/m²), particularly when lifestyle modification and pharmacotherapy have been insufficient. 1 Bariatric procedures can achieve the >10% weight loss threshold associated with fibrosis improvement. 1

Cirrhotic Stage Management

No MASH-targeted pharmacotherapy can currently be recommended for the cirrhotic stage. 1 Management focuses on:

  • Adaptation of metabolic drugs to cirrhosis stage 1
  • Nutritional counseling (high-protein diet for sarcopenia/decompensation; moderate weight reduction with high-protein intake for compensated cirrhosis with obesity) 1
  • Surveillance for portal hypertension and hepatocellular carcinoma 1
  • Liver transplantation evaluation for decompensated cirrhosis 1

Monitoring Treatment Response

Non-Invasive Monitoring

At the individual level, non-invasive tests may be repeatedly used to assess fibrosis progression but provide limited information about treatment response. 1 In clinical trials, changes in non-invasive markers have been associated with histological response:

  • MRI-PDFF relative reduction ≥30% 1
  • ALT reduction ≥17 U/L 1

Role of Liver Biopsy

Liver biopsy is not suited for monitoring disease evolution or response to therapy in routine clinical practice due to invasiveness and procedure-related limitations. 1 However, in individual cases and clinical trials, liver biopsy can be used to monitor disease progression or response to treatment. 1

Multidisciplinary Care Model

Given the multidirectional connections between MASLD and cardiometabolic comorbidities (cardiovascular disease, chronic kidney disease, type 2 diabetes), a multidisciplinary approach is mandatory to ensure all components are appropriately targeted to improve both liver-related and extrahepatic outcomes. 1 This includes:

  • Hepatology/gastroenterology for liver-specific management 1
  • Endocrinology for diabetes and metabolic optimization 1
  • Cardiology for cardiovascular risk management 1
  • Nutrition/dietetics for dietary intervention 1
  • Behavioral therapy for self-monitoring, motivation, goal-setting, and overcoming barriers 1

Critical Pitfalls to Avoid

  1. Underestimating weight loss requirements: Achieving only 3-5% weight loss is insufficient for meaningful histological improvement in MASH; target ≥7-10% for inflammation and fibrosis benefits. 1

  2. Relying solely on diet quality without weight loss: While Mediterranean diet improves liver injury markers, weight reduction remains essential for histological endpoints. 1

  3. Prescribing nutraceuticals: Despite marketing claims, there is insufficient evidence for effectiveness or safety. 1

  4. Using MASH-targeted pharmacotherapy in cirrhosis: Current evidence supports resmetirom only in non-cirrhotic MASH with significant fibrosis. 1

  5. Neglecting extrahepatic outcomes: Cardiovascular disease is the leading cause of death in MASLD patients, not liver-related complications; comprehensive cardiometabolic management is essential. 2

Treatment Goals and Outcomes

The ultimate treatment goals prioritize: 1

  • Quality of life and survival
  • Cardiometabolic benefits
  • Prevention of cirrhosis, hepatocellular carcinoma, type 2 diabetes, and cardiovascular disease

Regression of fibrosis by one stage has been associated with reduced risk of liver-related outcomes. 1 Resolution of steatohepatitis has been associated with fibrosis regression. 1 However, improved mortality has not yet been demonstrated for any treatment-induced histological changes; long-term follow-up studies are needed. 1
