HBeAg-negative Patients with Chronic Hepatitis B Virus Infection and Normal Alanine Aminotransferase: Wait or Treat?

Alanine aminotransferase (ALT) is a common clinical indicator of liver inflammation. The current Chinese guidelines for the management of chronic hepatitis B (CHB) recommend antiviral treatment for patients with detectable hepatitis B virus (HBV) DNA and persistent ALT levels (ALTs) exceeding the upper limit of normal. However, it has been recently reported that patients with chronic HBV infection, especially HBeAg-negative patients with persistently normal ALTs, may have liver biopsy findings of significant inflammation and fibrosis. For HBeAg-negative patients with chronic HBV infection and normal ALTs, many controversial questions have been asked. To treat or not? When to initiate the treatment? Which drug is appropriate? In this review, we summarize the available data on the management of HBeAg-negative patients with chronic HBV infection and normal ALTs with the aim of improving the current clinical management.
