['Nonalcoholic steatohepatitis (NASH) is a liver disease characterized by lipid accumulation and inflammation. Here, we aimed to evaluate plasma IL-1Ra as a marker for NASH and to determine whether diagnosis of NASH can be further improved by adding IL-1Ra measurements.', 'Therefore, plasma concentrations of IL-1Ra were measured from 146 subjects of a biopsy-proven NASH cohort with matched controls.', 'NASH patients had higher levels of plasma IL-1Ra compared with patients with steatosis or healthy controls.'] Do plasma IL-1 receptor antagonist levels correlate with the development of non-alcoholic steatohepatitis?
