Abstract:

Chronic hepatitis C virus (HCV) infection results in the development of liver fibrosis and cirrhosis in 20 to 25% of patients. The main task of the physician when examining a patient with a verified HCV infection is to identify the activity of inflammatory and necrotic processes in the liver, as well as the stage of fibrosis, and the reversibility of detected changes. Along with other clinical and laboratory parameters, this plays a major role in forecasting the course of hepatitis, as well as determines the therapeutic approach in each specific case. Liver biopsy remains the best way to assess the severity of chronic hepatitis C. The risk of developing cirrhosis depends on the stage (degree of fibrosis) and the grade (degree of inflammation and necrosis) observed in the initial liver biopsy. Non-invasive diagnostic approaches attempt to evaluate the serum markers of fibrogenesis. Biochemical markers of fibrosis scoring include thrombocyte counts, the prothrombin time, ratio of alaninaminotransferase (ALT) and aspartataminotransferase (AST) levels, the level of gglutamyl transferase and the quantity of blood serum albumin. Another set of markers is based on the detection of molecular junctions that activate fibrosis, or participate in the generation of the liver extracellular matrix. The most applicable include hyaluronic acid (HA), type IV collagen (IV-C), N-terminal propeptide of type III procollagen (PIIIP), metalloproteinases (MMP), inhibitors of metalloproteinases (TIMP), and growth-transforming factor betta (GTFbeta). The review discusses the clinical significance of each of the criteria and possibility of their combination in the non-invasive monitoring of liver fibrosis. (250 words)
