BACKGROUND & AIMS: Patients with acute-on-chronic liver failure (ACLF) have high mortality. Cirrhotics with acute kidney injury (AKI) have poor outcome but relevance of AKI and response to terlipressin in ACLF is not known.
METHODS: Consecutive ACLF patients with AKI at admission were compared with those without AKI (controls) for mortality at day 7, month 1 and 3, presence of hepatic encephalopathy (HE), spontaneous bacterial peritonitis (SBP) and acute variceal bleed (AVB). Patients were also compared based on severity of AKI (mild; S.cr 1.5-3 mg/dl and marked; S.cr >3 mg/dl). Response to terlipressin was also evaluated.
RESULTS: Of 241 ACLF patients, 55 (22.8%) had AKI at admission. Patients with AKI had higher mortality at day 7, 1 and 3 month and more often developed HE [54.1% vs. 30.6%; P = 0.001] and SBP [9.1% vs. 5.9%; P = 0.02]. Patients with marked AKI neither had higher mortality or complications in comparison to mild AKI. Presence of AKI [Odds ratio; OR, 2.4], S.bilirubin >20 mg/dl [OR, 3.1] and INR [OR, 2.9] were independent baseline predictors of mortality. Terlipressin was used in 28 of 55 patients with AKI who were volume non-responsive (hepatorenal syndrome, AKI-HRS). Ten (35.7%) of these showed response (S.Cr < 1.5 mg/dl) [median 4 days] and had lower mortality compared to terlipressin non-responders (10% vs. 50%, P = 0.05). There was no difference in terlipressin response in mild vs. marked AKI.
CONCLUSIONS: Almost one-fourth of the ACLF patients have AKI at admission and presence of AKI, but not its severity predicts complications and high mortality. Terlipressin effectively reverses AKI-HRS within a week in ~35% of ACLF patients resulting in improved survival.
