Ascites' neutrophil function is significantly impaired in patients with decompensated cirrhosis but can be restored by autologous plasma incubation.

ABSTRACT: Systemic immune cell dysfunction is a typical feature of liver diseases and increases the risk of bacterial infection, especially spontaneous bacterial peritonitis. We evaluated functional properties of neutrophil granulocytes in blood and ascites of patients both with and without decompensated cirrhosis. We collected blood and ascites samples from 63 patients with cirrhosis and eight without cirrhosis. Phagocytosis activity (PA) and oxidative burst activity (OBA) were evaluated after ex vivo stimulation with E. coli, while fluorescence signals were measured by flow cytometry. Ascites' neutrophil function tests were repeated after incubation with autologous plasma. Ascites' neutrophils showed an impaired PA and OBA (median blood PA 98.1% (86.8-99.8) vs. ascites' PA 50.5% (0.4-97.3), p?

Project description:Background and aimsAcute kidney injury (AKI) increases mortality in cirrhosis. Early identification of the cause of AKI helps in planning appropriate management. We aimed to find whether neutrophil gelatinase-associated lipocalin (NGAL) can be used to differentiate between different types of AKI in cirrhosis and predict short-term outcomes in patients with decompensated cirrhosis and AKI.MethodThis was a time-bound study in which consecutive hospitalized patients with cirrhosis and AKI were prospectively recruited and managed as per standard care. Acute on chronic liver failure (ACLF) was diagnosed as per the EASL-CLIF Acute-on-Chronic Liver Failure in Cirrhosis (CANONIC) criteria. Urine NGAL was measured by enzyme-linked immunosorbent assay (ELISA) by Epitope Diagnostics Inc. kit (San Diego, USA.) in all patients on admission, and patients were followed up until hospital discharge or death.ResultsA total of 110 consecutive patients (median [range] age: 44 [28-81] years;87.3%were male; ACLF: 71.8%; acute decompensation 28.2%; Model for end-stage liver disease (MELD) 27 [13-46]; Child-Turcotte-Pugh (CTP) 11 [7-15]) with cirrhosis and AKI were recruited. Alcohol was the most common etiology of cirrhosis(64.5%)). Pre-renal azotemia (PRA) was the most common cause of AKI (n = 56). Urine NGAL was significantly elevated in acute tubular necrosis (ATN) (1747 [6-6141] ng/ml than in hepatorenal syndrome (HRS) (379 [33.5-2320] ng/ml; P < 0.0001) and PRA (167 ng/ml [3.34-660]; P < 0.0001). Sixty-four percent patients with ATN, 27.6% patients with HRS, and none with PRA required dialysis. A total of 79.31% patients with HRS and 76% with ATN died. Urine NGAL was significantly higher in patients who required hemodialysis than in those who did not (1733 [243-6141] ng/ml vs 235 [3.34-2320] ng/ml; P < 0.0001). Both urine NGAL (n = 110) and plasma NGAL (n = 90) were significantly higher in patients who died (urine NGAL: -475 [6-6141] ng/ml vs 247 [3.34-2320] ng/ml; P = 0.002;plasma NGAL-950 [94-4859] ng/ml vs 608 [18-3300)]g/ml; P < 0.001). On multivariate analysis, urine NGAL and INR could predict mortality.ConclusionNGAL can differentiate between different types of AKI in cirrhosis and predict the need for hemodialysis and mortality in decompensated cirrhosis with AKI.
