RESUMEN
BACKGROUND: Guidelines recommend kidney transplant alone (KTA) in compensated cirrhosis based on a few small studies, but this is not widely performed despite its potential benefit to patients and the organ supply. Our aim was to determine the outcomes of KTA in patients with compensated cirrhosis. STUDY DESIGN: From 1/2012 to 12/2021, outcomes in KTA recipients with compensated cirrhosis were retrospectively compared to patients with chronic liver disease (CLD) but no cirrhosis. Patients with compensated cirrhosis were also compared to a matched cohort (based on age, time on hemodialysis, sex, and ethnicity) of KTA recipients without CLD. The outcomes included patient survival, allograft failure, allograft rejection, serious infection, liver decompensation, and length of stay (LOS). RESULTS: Over 9 years, 1562 KTAs were performed, with 150 (9.6%) patients having CLD mostly due to chronic hepatitis C, and a median follow-up of 3.5 years. 32/150 (21%) had compensated cirrhosis at the time of KTA with a mean MELD-Na of 22 (1.5). Matched controls (n = 189) were identified. We found no differences in patient survival (p = .07), allograft failure (p = .6), allograft rejection (p = .43), rates of serious infection (p = .31), as well as LOS (p = .61) among patients with compensated cirrhosis compared to patients with CLD but no cirrhosis, but with higher rates of liver decompensation (p = .004). Similarly, compared to patients without CLD, patients with cirrhosis had similar rates of patient survival (p = .20), allograft failure (p = .27), allograft rejection (p = .62) and LOS (p = .19) but with higher rates of serious infections (p = .001). CONCLUSIONS: Our study supports the safety and efficacy of KTA in patients with compensated cirrhosis.

Tremendous effort has been put forth over the past 2 decades in understanding the pathophysiology of nonalcoholic fatty liver disease/nonalcoholic steatohepatitis (NAFLD/NASH). Although multiple potential targets for drug development exist, there have been no approved therapies for NAFLD/NASH. Lipotoxicity, owing to increased delivery of fatty acids to the liver, and hepatic de novo lipogenesis are key drivers of disease pathogenesis. Moreover, genetics, environmental factors, and comorbid conditions converge to determine disease progression in individual patients. Given the complexity and heterogeneity of disease pathogenesis, numerous therapeutic targets have emerged and have been tested in clinical trials. Early trial failures have provided key lessons and foundational insights to move the field forward. Current ongoing phase 3 trials and emerging phase 2 trials are reasons for optimism, and 2 drugs, obeticholic acid and resmetirom, are being evaluated for accelerated approval by the US Food and Drug Administration this year. This article highlights key features of NASH pathophysiology and drug targets, the lessons learned from completed trials, and the current landscape of phase 2 and 3 clinical trials in NASH.
