Abstract

Background: Deterioration of renal function in cirrhotic patients with spontaneous bacterial peritonitis (SBP) is a predictor for inhospital mortality. However, the clinical significance of renal dysfunction during bacterial infection other than SBP is unknown.
aim: To investigate the prevalence and clinical significance of renal dysfunction due to bacterial infections other than SBP in patients with liver cirrhosis.
methods: Retrospective data from in-patients with bacterial infections other than SBP were analyzed.
results: Eighty-two patients were recruited for the analysis. Infection was located in urinary tract (41.5%), pneumonia (34.1%), biliary tract (3.7%), cellulitis (6.1%), gastrointestinal tract (4.9%) and bacteremia of unknown origin (9.7%). Renal dysfunction developed in 40 patients (48.8%), of which 13 patients had irreversible renal dysfunction. In the univariate and multivariate analysis, the initial MELD score, neutrophil count, bilirubin, and blood pressure were significant risk factors for renal dysfunction.
Conclusion: The prevalence of renal dysfunction during bacterial infection other than SBP in patients with liver cirrhosis was 48.8%, and its development was related to the severity of the liver disease. Occurrence of irreversible renal dysfunction seemed to affect the prognosis of these patients.
