- W179452023 abstract "The reliability of serum aminotransferase (ASAT and ALAT) levels, currently used in deciding on performing liver biopsy and to assess interferon therapy in chronic hepatitis C has been questioned. In Belgium, interferon therapy is actually only reimbursed for treatment of chronic hepatitis C when serum aminotransferase levels are more than twice the upper limit of normal. The aim of the present study was to assess the relationship between serum aminotransferase levels and histological severity of chronic hepatitis C. Sixty-seven liver biopsies from 51 different patients with chronic hepatitis C and presenting with elevated ASAT and/or ALAT levels, were retrospectively evaluated using the original terminology (minimal hepatitis, chronic persistent hepatitis, chronic active hepatitis, cirrhosis), the Knodell score and the components of the Bianchi-Gudat score, where grading (portal inflammation, piecemeal necrosis, intra-acinar necrosis and inflammation) and staging components (fibrosis/ cirrhosis) are quantitated separately. The correlation between amino-transferase levels measured at or near to the biopsy date and histological criteria were evaluated using Spearman's rank correlation. About one third of the patients, including patients with chronic active hepatitis and cirrhosis, presented with ASAT and ALAT levels less than twice the upper limit of normal. ASAT levels correlated with originally determined histological severity, the numerical Knodell score and the numerical scores for piecemeal necrosis, for intra-acinar necrosis and inflammation and for fibrosis in the Bianchi-Gudat score. ALAT levels correlated only with intra-acinar necrosis and inflammation. It is concluded that limiting interferon therapy to patients with aminotransferase levels over twice the upper limit of normal excludes a large proportion of patients from potentially curative treatment. ASAT levels are more useful than ALAT to assess the histological severity of the disease, probably because this mitochondrial enzyme is present in higher quantities in the liver as compared to the cytosolic ALAT, and is more released when tissue damage is more severe." @default.
