From the Guidelines
Treatment for patients with hepatitis B core antibody positive and surface antigen positive should involve antiviral medications, with first-line options including entecavir 0.5 mg daily or tenofovir disoproxil fumarate 300 mg daily, as these have been shown to effectively suppress viral replication and improve liver function 1. The goal of treatment is to eliminate or significantly suppress HBV replication, thereby preventing progression of liver disease to cirrhosis, liver failure, or hepatocellular carcinoma (HCC) 1. Key considerations in choosing a therapy include efficacy, safety, resistance, and method of administration 1. Some key points to consider when treating these patients include:
- Baseline assessments should include HBV DNA levels, liver function tests, complete blood count, renal function, and assessment for cirrhosis 1
- Regular monitoring every 3-6 months is necessary to evaluate treatment response and detect potential side effects 1
- Treatment goals are to suppress viral replication, normalize liver enzymes, and prevent progression to cirrhosis and hepatocellular carcinoma 1
- Entecavir and tenofovir have high barriers to viral resistance and can lead to regression of fibrosis and frequently even reversal of cirrhosis 1
- For pregnant patients who are HBV-positive, antiviral therapy in the third trimester may be recommended to reduce transmission risk, and all infants born to HBV-positive mothers should receive HBV immunoglobulin and vaccination at birth 1

From the Research
Hepatitis B Treatment
The treatment for a patient with hepatitis B (HBV) core antibody positive and surface antigen positive is primarily focused on suppressing HBV DNA replication and improving liver inflammation and fibrosis.
- The available treatment options include pegylated interferon and nucleos(t)ide analogues such as lamivudine, adefovir, entecavir, tenofovir disoproxil, and tenofovir alafenamide 2.
- Nucleos(t)ide analogues are considered as first-line therapy due to their high genetic barrier to resistance and potent antiviral action 3.
- Long-term viral suppression is associated with regression of liver fibrosis and reduced risk of hepatocellular carcinoma in cohort studies 2.
Treatment Duration and Resistance
- Pegylated interferon therapy can be completed in 48 weeks and is not associated with the development of resistance, but its use is limited by poor tolerability and adverse effects 2.
- Nucleos(t)ide analogues require long-term treatment with a potential risk of induction of drug resistance, but higher rates of viral replication suppression are achieved 3.
- Newer agents such as entecavir, tenofovir disoproxil, and tenofovir alafenamide may be associated with a significantly reduced risk of drug resistance compared to older agents 2.
Specific Treatment Regimens
- Combination therapy with entecavir and tenofovir may prevent post-liver transplant hepatitis B recurrence even without hepatitis B immunoglobulin maintenance therapy 4.
- Adefovir dipivoxil may be effective in preventing de novo hepatitis and resistance in liver transplantation patients receiving hepatitis B core antibody-positive grafts 5.
- The presence of hepatitis B virus surface antigen mutations could play a role in hepatitis B virus reactivation during treatment with direct acting antivirals for hepatitis C virus infection 6.
