Subcutaneous Fat Density Is an Independent Predictor of Adverse Outcomes and Shows Early Improvement After Liver Transplantation.

New evidencecirrhosisliver transplantbiomarkerepidemiology
Clinical takeawayConsider assessing SAT density on routine CT scans in cirrhosis patients listed for liver transplantation to identify those at higher risk of mortality. No specific intervention is recommended yet, as this is an observational finding.
What it foundHigh subcutaneous adipose tissue (SAT) density (> -83 HU in women; > -74 HU in men) was associated with higher pre-transplant mortality (p = 0.005) and reduced overall survival (p = 0.005) in cirrhosis patients awaiting liver transplantation.
ContextThis study confirms and refines the prognostic role of body composition in cirrhosis, highlighting SAT density as a novel CT-derived marker for mortality risk in liver transplant candidates.

Our full summary of this standard

Refer patients with decompensated cirrhosis (including those with MELD-Na <15 or MELD 3.0 <15 if they have clinically significant portal hypertension, recurrent ascites, hepatic encephalopathy, or variceal bleeding), acute liver failure meeting King's College Criteria/UNOS Status 1A, or HCC within Milan/UCSF criteria for comprehensive multidisciplinary liver transplant evaluation, with MELD 3.0 driving UNOS waitlist allocation and MELD exception scoring for HCC/HPS/FAP. Optimize modifiable risk factors before listing (alcohol abstinence, HCV DAA treatment, vaccinations, DM/obesity/OSA and dental clearance) and use bridging/downstaging locoregional therapy for HCC while awaiting transplant. After transplant, maintain lifelong immunosuppression with tacrolimus plus mycophenolate ± tapered steroids alongside infection prophylaxis and recurrent-disease surveillance.
