A preliminary study of inflammatory markers in non-alcoholic steatohepatitis patients

Abstract

It was reported that C-reactive protein (CRP) levels increase in parallel with the progression of chronic liver diseases, such as chronic hepatitis and liver cirrhosis. Inflammatory markers, such as high sensitive C-reactive protein (hsCRP), ferritin, transferrin, albumin, alpha-1 acid glycoprotein (AAG), alpha-2 macroglobulin (AMG), alpha-1 anti-trypsin (AAT) and lipoprotein a [Lp(a)] were measured in coronary artery disease patients (CAD) and CAD patients with non-alcoholic steatohepatitis (NASH). In the present preliminary study an attempt was made to study whether there is an increase in the levels of CRP in CAD patients associated with NASH. CAD patients showed an increase in CRP and serum ferritin levels. In CAD patients with NASH along with an increase in the levels of serum ferittin (p<0.001), the levels of serum AMG and ceruloplasmin (CP) were also increased (p<0.01). The CAD patients with NASH had a higher proportion of diabetes, hypertension and dyslipidaemia compared to CAD patients. But how this difference contributes to the elevation in acute inflammatory markers particularly AMG and CP levels in CAD patients with NASH cannot be explained. This study shows that a substantial number of CAD patients may be associated with NASH. Non-invasive simple parameters that reflect the degree of inflammation and fibrosis of the liver in patients with NASH would facilitate improved understanding and treatment of the disease. Further studies may be necessary to evaluate the percentage of NASH patients progressing to CAD.
