A recording of this presentation is available HERE.
Deep gratitude to Dr. Will Holt, CPMC Hepatologist, who drove to SSRRH from Piedmont at the literal crack of dawn to teach us about Metabolic Dysfunction Associated Steatohepatitis (MASLD) and Alcohol-Associated Liver Disease (AASLD) and then changed hats to spend the morning with our residency leadership as a faculty leader for graduate medical education within Sutter.
His talk was fantastic! I recommend you watch it.
For those of you who prefer to read, the highlights:
First, MASLD
- We all known that the prevalence of obesity and diabetes have both skyrocketed over the last several decades-- nearing 50% in some regions of our country.
- Along with these metabolic issues, comes MASLD-- world prevalence is estimated to be 29.8% lowest rates for those of African descent (thought to be both genetic and food access/lifestyle related)
- Risk factors for MASLD include age >50, high BMI and DM2
- MASLD is a risk factor for death
- Assume that people are high risk (>50, high elevated BMI, DM2) have MASLD>> screen them for MASH with via fibroscan
- For everyone else with any component of metabolic syndrome (e.g. overweight, a1c>6%, hypertension, HDL<40 (F) and <50 (M), triglycerides>150)>> use FIB-4 to screen first
- if the FIB4>1.3>> Fibroscan,
- unless they are >65yo, then use FIB-4>2.0
- Fibroscan uses a weighted hammer/pulse to measure liver stiffness-- this is available through Sutter Airway)
- Fibroscan <8 is normal (=reassuring, low risk), >14 demonstrates cirrhosis
- for those with a normal fibroscan, focus on lifestyle modification for metabolic disorders
- for those with an abnormal fibroscan, refer to hepatology
- Fibrosis predicts liver-related mortality (see graph below from J. Hepatology 2017)
As per the 2024 AASLD Guidelines for clinical suspicion of steatotic liver disease
What are the treatment options for MASLD and MASH?- Pharmacologic:
- Vitamin E: 96 week RCT: reduced fibrosis 41% vs. 31% (placebo)
- Pioglitazone: meta-analysis, reduced fibrosis vs. placebo OR 1.77
- There are two FDA approved medications:
- Resmetirom (2024): TRH-beta agonist, 52 week RCT vs. placebo, reduced fibrosis 24% vs. 14%
- Semaglutide (2025): GLP1 agonist, 72 week RCT vs. placebo, reduced fibrosis 37% vs. 22%
- Non-Pharmacologic: diet/exercise/weight loss
Now, a little bit on ALD
- Defining Alcohol use disorder (AUD)
- Biomarkers for ETOH
- Urine tests (EtG, EtS) have a very short detection window (<48 hours)
- PEth is current "truth serum", gives us information about the last 30 days, though there are some false positives in the lower ranges (20-40). Very high results (>400-1000 are very reliable)
- Diagnosing Alcoholic Hepatitis can be tricky!
- elevated MCV (100), elevated WBC, jaundice
- Treatment of alcohol-associated hepatitis with prednisolone (rather than prednisone due to first pass metabolism, when not available, prednisone is acceptable) FOR:
- Patients WITH Maddrey Discriminant Function >32>>
- AND WITHOUT
- evidence of biliary obstruction on ultrasound
- uncontrolled infection (especially bacteremia)
- AKI with SCr>2.5
- UGI bleeding
- Severe shock/hemodynamically unstable
- Expect 3 month recovery (bili will remain high)
- You can wait a couple of days before starting prednisolone (e.g. if any of the above active), pts can still benefit with delayed start
- Use the Lille score to predict (7 days) who will respond
- N-Acetylcysteine= mixed bag, there does appear to be a mortality benefit at 30 days but not at 3 months/6 months (NEJM 2011, see image)
- What about liver transplant (LT) in ALD?
- 2011 RCT from France (NEJM 2011) was practice changing, randomized patients with AH without sobriety and first decompensating event to LT vs. no LT (only <10% deemed candidates)>> found that 1 and 3 year survival was the same for patients with ALD as any other liver disease
- This led to a change in practice in which transplant can/may be considered for alcoholic hepatitis in select patients, not specified as a specific duration of sobriety>> at CPMC, this is called the "limited sobriety pathway to LT"
- Careful patient selection for LT (with ALD) is key.
- Family support
- Absence of untreated psychiatric disorder
- Agreement by patient with support to LIFELONG abstinence (this can be harder to get to that you might imagine)
- This assessment is done by LT SW at CPMC (often via video visit prior to Transfer)
- We know that patients with AUD will relapse
