Conditions

Hepatitis B, Liver Cirrhosis

Brief summary

Patients who have completed 2 years follow-up of the past National 12th Five-Year Major Project on Infectious Diseases will receive another 8 years treatment with entecavir (10 years in total). Collect serology, imaging, and other clinical data to evaluate the incidence and mortality of decompensated cirrhosis and hepatocellular carcinoma. Understand the effects of long-term antiviral therapy on HBV-induced liver fibrosis/cirrhosis.

Detailed description

Patients who have completed 2-years entecavir-based treatment in Regress Study will receive another 8 years of entecavir extension therapy. Patients will be assessed at baseline and every six months for blood cell count, liver function test, HBV-DNA, AFP, prothrombin time, liver ultrasonography, and Fibroscan; A third liver biopsy will be performed at the 5th year of treatment in patients who have significant fibrosis at second biopsy. CT /MRI and endoscopy will be performed at baseline and the 5th and 10th year of treatment.
