Comparative Study
Impact of the etiology of acute kidney injury on outcomes following liver transplantation: acute tubular necrosis versus hepatorenal syndrome.
Acute kidney injury (AKI) at the time of liver transplantation (LT) has been associated with increased morbidity and mortality. In patients with potentially reversible renal dysfunction, predicting whether there will be sufficient return of native kidney function is sometimes difficult. Previous studies have focused mainly on the effect of the severity of renal dysfunction or the duration of pretransplant dialysis on posttransplant outcomes. ⋯ At 5 years, the incidence of chronic kidney disease (stage 4 or 5) was statistically higher in the ATN group versus the HRS group (56% versus 16%, P < 0.001). A multivariate analysis revealed that the presence of ATN at the time of LT was the only variable associated with higher mortality 1 year after LT (P < 0.001). Our study is the first to demonstrate that the etiology of AKI has the greatest impact on patient and renal outcomes after LT.

Severe liver disease affects 4.5% to 10% of individuals with cystic fibrosis (CF) and is the third-leading cause of death. Liver transplantation (LT) is an accepted therapy, but the effects of liver disease and LT on pulmonary function in patients with CF are controversial. Our aim was to characterize changes in pulmonary function in LT patients with CF. ⋯ Both the (P = 0.003) and (P = 0.001) had a slower FEV(1) decline in the period before transplantation versus after transplantation. In conclusion, pulmonary function is lower and declines more slowly in patients with CF before LT versus, but parallels the decline in non-LT after transplantation. LT is neither beneficial nor detrimental to pulmonary function in CF but returns FEV(1) decline to the same trajectory found for matched non-LT individuals with CF.
