Outline of Final Research Achievements

The infection of hepatitis C virus (HCV) progresses to chronic hepatitis, cirrhosis, and hepatocellular carcinoma. Therefore we should diagnose the clinical stage exactly before starting treatment.We measured the liver stiffness (Vs) by the ultrasound and evaluated its correlation with the liver fibrosis stage and usefulness of the follow-up of Vs values during the Interferon (IFN) therapy.
The Vs values correlated with several blood fibrosis indexes (hyaluronic acid, APRI and FIB-4). Furthermore, the Vs values correlated with histological fibrosis stage (F0 - 4). A significant difference of Vs values was shown among the patients with different fibrosis stages. The cutoff of Vs values for each fibrosis stage was obtained. In the study of the follow-up of Vs values during the IFN therapy, the changes of Vs values reflected the different responses to the therapy. However, it seemed that the prediction of the response to IFN treatment by Vs values before treatment needs further studies.
