Comparative Post-Transplant Outcomes in Alcohol-Related Liver Disease and Non-Alcohol Steatohepatitis: A Multicenter...

Area of Science:

• Hepatology
• Transplantation Medicine
• Clinical Outcomes Research

Background:

• Liver transplantation (LT) is a crucial treatment for end-stage liver disease.
• Outcomes after LT can vary based on the initial cause of liver disease.
• Comparing alcoholic liver disease (ALD) and non-alcoholic steatohepatitis (NASH) etiologies is important for understanding post-LT prognosis.

Purpose of the Study:

• To compare clinical outcomes between liver transplant recipients with ALD and NASH.
• To identify specific complications and survival differences between these two patient groups.
• To provide real-world data on post-LT outcomes stratified by etiology.

Main Methods:

• Retrospective cohort study utilizing the TriNetX Research Network.
• Adult LT recipients were divided into ALD and NASH cohorts.
• Propensity score matching (1:1) was employed to ensure comparable baseline characteristics.
• Comparative analyses included risk ratios, hazard ratios, and Kaplan-Meier survival analysis.

Main Results:

• Alcoholic LT recipients showed significantly higher rates of rejection, hepatic encephalopathy, and acute kidney injury (AKI).
• Conversely, alcoholic LT recipients had lower frequencies of sepsis and chronic kidney disease (CKD).
• Kaplan-Meier analysis revealed lower rejection-free survival, increased hepatic encephalopathy, higher AKI risk, and greater all-cause mortality in the ALD cohort.

Conclusions:

• Alcoholic LT recipients experience a higher risk of complications and all-cause mortality compared to NASH LT recipients.
• Etiology of liver disease significantly impacts post-transplant outcomes.
• These findings underscore the need for tailored management strategies for LT recipients based on their underlying liver condition.
