Expanding antiviral therapy indications for HBeAg-negative chronic hepatitis B patients with normal ALT and positive HBV DNA

With the improved efficacy and accessibility of antiviral agents as well as the concerns about disease progression,there is a hot discussion on whether HBeAg-negative chronic hepatitis B(CHB)patients with normal alanine aminotransferase(ALT)and positive HBV DNA should be treated.According to the international guidelines on the stages of the natural history of HBV infection,HBeAgnegative CHB patients with normal ALT and positive HBV DNA can be divided into two groups:one is the well-known“inactive carrier phase”,which is defined as serum HBV DNA<2000 IU/ml and no significant liver inflammation;and the other is the“indeterminate phase”,which is defined as serum HBV DNA≥2000 IU/mL regardless of the pathological changes in liver tissue,or HBV DNA<2000 IU/mL but accompanied by significant pathological changes in the liver.In this minireview,we will expound the disease characteristics,disease progression,and clinical management status of these two groups.Based on the analysis,we propose that HBeAg-negative patients with normal ALT but detectable serum HBV DNA should be treated,regardless of their age,family history of hepatocellular carcinoma(HCC)or the severity of liver necroinflammation.Expanding the indications of antiviral therapy will help improve the survival and quality of life of patients by preventing disease progression,and consequently reduce the risk of HCC development.
