Increased serum leptin concentrations correlate with soluble tumour necrosis factor receptor levels in patients with cirrhosis

Abstract

Our study demonstrated that serum levels of TNF-alpha, sTNF-RI, sTNF-RII and leptin were all elevated in cirrhotic patients. The severity of liver cirrhosis was an important factor for the activation of TNF-alpha system. The activated TNF-alpha system conjointly with hyperleptinaemia might mediate malnutrition in patients with liver cirrhosis.
