Keeffe et al reported recommendations for treating a patient infected with hepatitis B virus (HBV). One category involves patients who are HBeAg-negative and without cirrhosis. The authors are from multiple universities in the United States.
Patient selection: HBeAg-negative, without cirrhosis
Parameters:
(1) HBV copies in IU/mL
(2) serum ALT
HBV copies |
Serum ALT |
Recommendations |
< 2,000 IU/mL |
normal |
Monitor every 3 months for 1 year, then every 6-12 months. Therapy may be indicated if liver biopsy shows significant disease. |
>= 2,000 IU/mL |
normal |
Therapy may be indicated if liver biopsy shows significant disease. Else monitor for elevation of serum ALT. |
>= 2,000 IU/mL |
elevated |
Treat with antiviral agents. |
where:
• The viral load decision point is 10% of that used for HBeAg-positive patients.
Liver biopsy may be helpful in guiding patients with a normal serum ALT, especially if the patient is >= 35 years of age.
Long-term treatment is usually required for oral drug regimens.
Use adefovir, entecavir or peginterferon alfa-2a as first-line options.
Purpose: To manage a patient with HBeAg positive hepatitis B viral infection in the absence of cirrhosis based on the recommendations of Keeffe et al.
