OBJECTIVE: To assess the production of the endogenous IL-1 modulators IL-1 receptor antagonist (IL-1Ra), type I and II soluble IL-1 receptors (IL-1sRI and II) in patients with chronic liver disease (CLD). MATERIAL AND METHODS: Plasma levels of IL-1beta (IL-1beta) and IL-1 modulators were assessed in 126 CLD patients and 39 healthy controls. IL-1sRII was also measured in the supernatants of primary hepatocyte cultures. RESULTS: Plasma IL-1sRI and IL-1Ra levels were significantly higher in cirrhotic CLD patients than in non-cirrhotic CLD patients and in controls. Levels did not depend on the etiology of CLD. Likewise, plasma IL-1beta levels were elevated in CLD patients compared with those in controls. In contrast, IL-1sRII levels did not differ between CLD patients and controls. Cultures of human primary hepatocytes showed that IL-1sRII is induced by IL-1beta, but not IL-6. CONCLUSIONS: In cirrhotic CLD patients elevated plasma IL-1beta is not counteracted by endogenous levels of IL-1sRII, whereas high IL-1sRI is expected to neutralize the naturally occurring antagonist IL-1Ra, resulting in a dysregulation of the IL-1 system that might enhance pro-inflammatory activity of IL-1.
