Background and aims
Nonselective beta-blockers (NSBB) protect patients with compensated cirrhosis; however, it is unclear if NSBB is associated with acute kidney injury (AKI) in patients with decompensated cirrhosis. We aimed to determine if the use of NSBB was associated with an increased risk of stage II AKI or greater and waitlist mortality (WLM) among patients with decompensated cirrhosis awaiting liver transplant stratified by cirrhosis severity.Methods
Included were 1816 outpatients listed for liver transplantation at UCSF from June 2012 to April 2022. Our primary outcome was stage 2 AKI (>200% increase in serum creatinine). Our secondary outcome was WLM (all-cause mortality). Our primary exposure was the use of any NSBB derived using natural language processing of clinical notes. Multivariable Cox proportional hazards models with time-dependent variables were used to determine the HR of NSBB use on stage 2 AKI and WLM, stratified by Child-Pugh Score.Results
The average age of the cohort was 58 years old, with 35% identifying as female. In multivariable time-dependent models, NSBB use was associated with 1.53 × (95 CI 1.19-1.97) the hazard of stage 2 AKI in the cohort overall and 1.80 × (95 CI 1.26-2.57) among those with Child C cirrhosis, respectively. Similarly, NSBB use was associated with 1.30 × (95 CI 1.07-1.59) and 1.45 × (95 CI 1.03-2.03) the hazard of WLM, overall and in Child C, respectively. NSBB use was not significantly associated with AKI nor WLM among those with Child A.Conclusion
NSBB use is associated with Stage 2 AKI and WLM in patients awaiting liver transplantation and Child C cirrhosis. These data suggest cautious use of NSBBs in patients in this population.Many UC-authored scholarly publications are freely available on this site because of the UC's open access policies.
