Liver Transplantation for Nonalcoholic Steatohepatitis in the US: Temporal Trends and Outcomes DIGESTIVE DISEASES AND SCIENCES Cholankeril, G., Wong, R. J., Hu, M., Perumpail, R. B., Yoo, E. R., Puri, P., Younossi, Z. M., Harrison, S. A., Ahmed, A. 2017; 62 (10): 2915–22


Nonalcoholic steatohepatitis (NASH) is a rapidly growing etiology of end-stage liver disease in the US. Temporal trends and outcomes in NASH-related liver transplantation (LT) in the US were studied.A retrospective cohort study utilizing the United Network for Organ Sharing and Organ Procurement and Transplantation (UNOS/OPTN) 2003-2014 database was conducted to evaluate the frequency of NASH-related LT. Etiology-specific post-transplant survival was evaluated with Kaplan-Meier methods and multivariate Cox proportional hazards models.Overall, 63,061 adult patients underwent LT from 2003 to 2014, including 20,782 HCV (32.96%), 9470 ALD (15.02%), and 8262 NASH (13.11%). NASH surpassed ALD and became the second leading indication for LT beginning in 2008, accounting for 17.38% of LT in 2014. From 2003 to 2014, the number of LT secondary to NASH increased by 162%, whereas LT secondary to HCV increased by 33% and ALD increased by 55%. Due to resurgence in ALD, the growth in NASH and ALD was comparable from 2008 to 2014 (NASH +50.15% vs. ALD +41.87%). The post-transplant survival in NASH was significantly higher compared to HCV (5-year survival: NASH -77.81%, 95% CI 76.37-79.25 vs. HCV -72.15%, 95% CI 71.37-72.93, P < .001). In the multivariate Cox proportional hazards model, NASH demonstrated significantly higher post-transplant survival compared to HCV (HR 0.75; 95% CI 0.71-0.79, P < .001).Currently, NASH is the most rapidly growing indication for LT in the US. Despite resurgence in ALD, NASH remains the second leading indication for LT.
