Assessment of Liver Fibrosis and Prognosis in Chinese Patients With CHB Infection Using STE/STQ Elastography

Third Affiliated Hospital, Sun Yat-Sen University460 enrolled

Overview

This national multicenter prospective study is aimed to study the diagnositic performance of STE/STQ elastography in liver fibrosis and prognosis in patients with chronic hepatitis B infection.

Ultrasound liver elasticity measurement and imaging has not only been proposed as an alternative to evaluate the severity of chronic liver fibrosis, but also as a mean to stratify patients with advanced fibrosis according to risks of occurrence of clinical complications of end-stage liver diseases. Sound touch elastography (STE）and sound touch quantify (STQ) developed by Mindray Resona 7 imaging system provide both two-dimensional and point shear-wave elastography of tissue elasticity with stronger penetration and easy operation. This analysis will study the diagnositic performance of STE/STQ elastography for lver fibrosis and the prognostic value of STE/STQ elastography for the prediction of clinical complications of chronic liver diseases.

Inclusion Criteria: * Patients undergoing a liver ultrasound exam due to confirmed Hepatitis B infection , * Patients having reached the age of majority in China, * Patients with a liver biopsy for histological evaluation of liver fibrosis, performed within 3 months after the STE/STQ measurement date, and having the recommended quality criterion: minimal length of biopsy samples of 15 mm, stored in paraffin minimal number of portal tracts of 6 per biopsy samples * Patients of Chinese ethnic origin. Exclusion Criteria: Any of the conditions below will exclude patients from the study: * Any patient presenting with combined etiologies of chronic liver diseases:，including Non hepatitis B viral infection（Hepatitis A, C, D, E）, alcoholic chronic liver disease, hemochromatosis, autoimmune hepatitis，etc * Any patient presenting with a co-infection of HIV * Any patient presenting with combined liver tumor * Any patient ever received liver transplantation * Pregnant women * Acute hepatitis

Outcomes

Primary Outcomes

Degree of Liver Fibrosis

All liver biopsies will be taken for evaluating the degree of liver fibrosis according to the METAVIRE classification. The degree of fibrosis is classified in a 0-4 scale as follows: F0: no fibrosis, F1: portal fibrosis alone, F2: portal fibrosis with rare septa, F3: portal fibrosis with many septa, and F4: cirrhosis.

Time frame: 1-2 years

Secondary Outcomes

Complication rates depending on liver STE/STQ measurement values at baseline

Clinical complications in our study protocol are: ascites, hepatic encephalopathy, esophageal varices, fundal varices, variceal bleeding, liver failure, HCC and death. The complication rates are regarded as occurrence of clinical complications in patients with chronic hepatitis B.

Time frame: 2 years
