Clinical evidence of outcomes following liver transplantation in patients with nonalcoholic steatohepatitis: an updated meta-analysis and systematic review
Open accessAbstract
OBJECTIVE: Nonalcoholic steatohepatitis (NASH) is a dramatically growing indication for liver transplantation (LT) worldwide and the posttransplant outcomes of NASH patients are currently under intensive investigation. This quantitative meta-analysis aimed to update the clinical evidence on outcomes of transplanted patients with NASH. METHODS: We performed a systematic review and meta-analysis of studies (published up to September 15, 2021) that focused on LT outcomes for NASH versus non-NASH patients. Random-effect meta-analysis was conducted to calculate pooled odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup analyses based on crucial baseline clinical characteristics and leave-one-out sensitivity analyses were conducted to assess the robustness of the pooled results. Meta-regression was used to evaluate study-level demographic, clinical, and biochemical characteristics to identify potential confounders affecting patient survival. RESULTS: Twenty-two non-randomized comparative studies with 1,538 NASH and 6,014 non-NASH patients were included. 1- (OR, 0.94; 95% CI, 0.77-1.14), 3- (OR, 0.82; 95% CI, 1.00-1.22), and 5- (OR, 1.05; 95% CI, 0.84-1.31) year patient survival was equivalent between NASH and non-NASH recipients. NASH patients were associated with similar cardiovascular mortality (OR, 1.36; 95% CI, 0.89-2.09) and retransplantation rates (OR, 0.69; 95% CI, 1.03-1.53), lower graft failure-related mortality (OR, 0.11; 95% CI, 0.29-0.74), but higher sepsis-related mortality (OR, 1.53; 95% CI, 1.13-2.06). Meta-regression revealed that a higher proportion of patients with hepatocellular carcinoma (HCC) were associated with significantly superior overall patient survival at 1 (P = 0.044), 3 (P = 0.035) and 5 (P = 0.049) years after LT in NASH compared with non-NASH. CONCLUSIONS: This study shows no difference in posttransplant survival between NASH and non-NASH patients. Carefully selected patients with NASH-related HCC may benefit from LT. NASH recipients should be managed with caution posttransplant, especially regarding the potentially high risk of sepsis-related death.

Long-term graft and recipient survival after liver transplantation do not differ in many retrospective and registry analyses between adults with MASLD and others.
“Despite the overall higher rate of risk factors in adults with MASLD, long-term graft and recipient survival after liver transplantation do not differ in many retrospective and registry analyses, 482,486,487 supporting that candidates with MASLD can be safely transplanted, if properly”
From EASL-EASD-EASO Clinical Practice Guidelines on the management of metabolic dysfunction-associated steatotic liver disease (MASLD). (2024) · cites this paper as [487]
Sections 3.2.2–3.2.3 report similar 3- and 5-year patient survival after transplantation for NASH and non-NASH recipients. The paper does not establish equivalent long-term graft survival: Section 3.3.3 instead reports lower graft failure-related mortality in the NASH group. Its comparison concerns NASH, which is narrower than MASLD. (LLM, conf=0.86)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
