Kirchner JT. 5(March 1, 2019) Annually, approximately 0.5% of individuals with inactive chronic hepatitis B will have spontaneous clearance of HBsAg, and most will develop anti-HBs.2 Among adults with untreated chronic hepatitis B, the cumulative five-year incidence of cirrhosis is 8% to 20%, and the risk of HCC is 2% to 5%.2, The risk of liver-related complications is variable and influenced by a variety of host, viral, and environmental factors.2 Determining the stage of liver disease (e.g., evidence of inflammation, fibrosis) is important to guide therapeutic decisions and the need for HCC screening.2 Although liver biopsy is recommended for assessing inflammatory activity and fibrosis, noninvasive tests, such as transient elastography or a serum fibrosis panel, are also useful.2.
