Independent prognostic factors in patients with liver cirrhosis

Abstract

Background/aims: Evaluation of the urgency of the liver transplantation in individual patients may help to prioritize patients at risk of death. Consequently we undertook the search for independent prognostic factors in patients with liver cirrhosis.

Methodology: The study group was composed of 219 patients with liver cirrhosis, treated in our Department, from 1996 to 2005. Patients' files were examined for details of physical findings, results of laboratory examinations, and patients' survival. Prognostic significance of 15 variables was analyzed. All prognostic factors which turned out to be statistically significant in univariate analysis were included in the Cox proportional hazard model.

Results: Child-Turcotte-Pugh (CTP) score B (p<0.001; hazard ratio (HR): 13.33), CTP score C (p<0.001; HR=7.45), presence of hepato-renal syndrome (p<0.001; HR=3.54), history of esophageal bleeding (p=0.048; HR=1.63) and presence of peripheral edema (p=0.034; HR=1.61) were found to be independently associated with survival. Model of End-stage Liver Disease score, etiology of cirrhosis, sex, ascites, bacterial spontaneous peritonitis, encephalopathy, serum creatinine concentration, INR and serum bilirubin concentration were shown to be significantly associated with patients' prognosis, however not independently.

Conclusions: Analysis of presence of common clinical symptoms is crucial for evaluation of patients' prognosis.
