Abstract
BackgroundDecompensated liver cirrhosis (DLC) is now known as a chronic inflammatory process, evidenced by elevated levels of circulatory pro-inflammatory cytokines and chemokines which in turn lead to the development of more hepatic decompensation and multi-organ failure. Resistin has a pro-inflammatory effect through the production of several cytokines (e.g., IL-1, IL-6, IL-12, and TNF-α) and cell adhesion molecules. Interleukin-6 (IL-6) is a proinflammatory cytokine playing a crucial role in acute phase responses and in regulating immune reactions through activation and differentiation of T and B lymphocytes. The current study aimed to evaluate the value of serum resistin and IL-6 as biomarkers of DLC and their role as prognostic markers of complications in these patients.ResultsThis study was conducted on 90 patients divided into three groups: group I—30 patients with compensated cirrhosis (CLC); group II—40 patients with DLC; and group III consisted of 20 healthy controls. Serum resistin and IL-6 levels were statistically significantly higher in patients with DLC compared to patients with CLC at baseline. A cut-off value of > 302 pg/ml for serum resistin was found to discriminate between CLC and DLC with a specificity of 73.33% and sensitivity of 92.50% and a cut-off level of > 31 pg/mL for IL-6 differentiated between the two groups with a sensitivity of 85.0% and specificity of 76.67%. Patients with DLC were followed up for 3 months, 10 patients (25%) passed away, and 19 patients out of the remaining 30 (63.3%) patients developed complications including acute kidney injury, spontaneous bacterial peritonitis, variceal hemorrhage, encephalopathy, and hepatocellular carcinoma. Serum resistin and IL-6 were found to be significantly higher at baseline in those patients who developed complications or mortality after the follow-up period. In addition, there were positive correlations between IL-6 and resistin and MELD-NA and CRP.ConclusionSerum resistin and IL-6 could be used as sensitive diagnostic and prognostic biomarkers of decompensated cirrhotic patients.
