The value of ascitic neutrophil gelatinase-associated lipocalin in decompensated liver cirrhosis with spontaneous bacterial peritonitis

Abstract

Background: Spontaneous bacterial peritonitis (SBP) is one of the most critical complications of decompensated liver cirrhosis. This study aimed to assess whether ascitic neutrophil gelatinase-associated lipocalin (NGAL), a reliable inflammation biomarker, can be used to detect SBP in decompensated cirrhosis patients and to predict mortality from decompensated cirrhosis-related SBP. Methods: This study included 204 hospitalized patients with ascites of decompensated liver cirrhosis and follow-up of 28 days. We measured ascitic NGAL levels by the latex-enhanced immunoturbidimetric method. Simultaneously, we observed the patterns of ascitic NGAL levels in the SBP group after 7 days of anti-infection treatment with third-generation cephalosporins. Results: The ascitic NGAL levels significantly increased in the SBP group compared with that in the non-SBP group, 111(83.9, 178) ng/mL vs 48(35.4, 63) ng/mL, P
