Outcomes of renal dysfunction in patients with acute liver failure.


ABSTRACT:

Background

Although acute kidney injury (AKI) often accompanies acute liver failure (ALF), its impact on long-term outcome is unknown.

Objective

This study examines the incidence, severity and outcomes of AKI in patients with ALF.

Methods

A total of 134 ALF patients treated at Hannover Medical School between 1995 and 2013 were retrospectively analyzed.

Results

Fifty-four ALF patients (40.3%) demonstrated AKI, as defined by the acute kidney injury network (AKIN) classification, on intensive care unit (ICU) admission, and 85 patients (63.4%) developed AKI prior to ALF recovery, emergency liver transplantation (ELT) or death. AKI severity was closely associated with other end-organ damage (p?p?=?0.003). One-hundred-and-three (76.9%) patients reached the combined endpoint of ELT or death, and 42 (31.3%) patients died within 28 days. AKIN stage 3 at ICU admission was the strongest independent predictor of 28-day overall mortality (hazard ratio 3.48, 95% confidence interval 1.75-6.93, p?p?ConclusionsAKI is a frequent complication in ALF that correlates with remote organ damage and long-term creatinine levels and independently predicts outcome.
