From the Guidelines
Treatment for hepatitis B positive antigen with no viral load is not always necessary, and the decision to treat should be based on a complete evaluation of the patient's condition, including liver function tests, HBeAg status, liver fibrosis assessment, and clinical symptoms. According to the most recent and highest quality study, patients with HBeAg-positive CHB and HBV DNA < 2000 IU/mL, normal ALT levels, and no significant histologic disease may not require treatment and can be monitored every 6-12 months 1.
Key Considerations
- The goal of therapy for CHB is to eliminate or significantly suppress HBV replication and prevent progression of liver disease to cirrhosis, liver failure, or HCC.
- Treatment decisions should be individualized based on the patient's clinical picture, including liver function tests, HBeAg status, liver fibrosis assessment, and clinical symptoms.
- For patients with evidence of liver damage despite undetectable viral load, treatment with antiviral medications such as entecavir (0.5-1mg daily) or tenofovir (300mg daily) may be recommended.
- For patients with normal liver function and no evidence of significant fibrosis, monitoring without treatment is often appropriate, with regular follow-up every 3-6 months to check liver enzymes and viral markers.
Recommended Treatment Approach
- Entecavir or tenofovir monotherapy is the preferred initial therapy for CHB, due to their potent antiviral activity and high barriers to resistance 1.
- Combination therapy with entecavir and tenofovir may be considered in certain situations, such as in patients with high viral load at the start of treatment or in those with cirrhosis.
- Peginterferon-α is an alternative option for patients who are interferon-eligible and have a high likelihood of responding to therapy.
Monitoring and Follow-up
- Patients with HBeAg-positive CHB and HBV DNA < 2000 IU/mL, normal ALT levels, and no significant histologic disease should be monitored every 6-12 months.
- Patients with evidence of liver damage or significant fibrosis should be monitored more closely, with regular follow-up every 3-6 months to check liver enzymes and viral markers.

From the Research
Treatment of Hepatitis B Positive Antigen with No Viral Load
- The treatment of hepatitis B positive antigen with no viral load is a complex issue, and the approach may vary depending on the individual patient's circumstances 2, 3, 4, 5, 6.
- According to a study published in Gastroenterology, tenofovir and entecavir are the most effective antiviral agents for chronic hepatitis B, with tenofovir being the most effective in inducing undetectable levels of HBV DNA 2.
- Another study published in Drugs found that entecavir is an effective and generally well-tolerated treatment for chronic HBV infection, with a lower risk of resistance compared to lamivudine 3.
- A study published in the Journal of laboratory physicians compared the efficacy of tenofovir, entecavir, and a combination of lamivudine and adefovir in treating chronic hepatitis B, and found that tenofovir and entecavir monotherapies were more effective in reducing HBV-DNA levels than the combination therapy 4.
- A systematic review and meta-analysis published in the Virology journal found that lamivudine plus adefovir combination therapy was more effective than entecavir monotherapy in treating lamivudine-resistant chronic hepatitis B 5.
- A study published in the European journal of gastroenterology & hepatology found that monitoring hepatitis B virus DNA and quantitative hepatitis B surface antigen every 2 months is safe, and that antiviral prophylaxis can prevent hepatitis B virus reactivation in patients receiving immunosuppressive therapy 6.
Treatment Options
- Tenofovir and entecavir are considered the most effective antiviral agents for chronic hepatitis B 2.
- Entecavir is an effective and generally well-tolerated treatment for chronic HBV infection, with a lower risk of resistance compared to lamivudine 3.
- Lamivudine plus adefovir combination therapy may be considered for patients with lamivudine-resistant chronic hepatitis B 5.
- Antiviral prophylaxis may be necessary for patients receiving immunosuppressive therapy to prevent hepatitis B virus reactivation 6.
Monitoring and Follow-up
- Monitoring hepatitis B virus DNA and quantitative hepatitis B surface antigen every 2 months is recommended for patients receiving immunosuppressive therapy 6.
- Patients with hepatitis B positive antigen and no viral load should be closely monitored for signs of hepatitis B virus reactivation, such as an increase in HBV DNA or quantitative hepatitis B surface antigen levels 6.
