Which treatment is indicated for a patient with chronic hepatitis B who has elevated ALT levels?

In the context of a patient with chronic hepatitis B and elevated ALT levels, the use of Alpha-interferon 2b is indicated as it serves to enhance the immune response against the hepatitis B virus. Elevated ALT levels are suggestive of active liver inflammation, and when present in conjunction with chronic hepatitis B infection, they signal a need for antiviral therapy to prevent further liver damage and to reduce the risk of progression to cirrhosis or hepatocellular carcinoma.

Alpha-interferon is a pegylated form that has been shown to elicit viral suppression, improve liver histology, and potentially achieve a sustained virologic response. This treatment is particularly appropriate in patients who meet the criteria for antiviral therapy, thus making it a crucial option for managing elevated ALT in the context of chronic hepatitis B.

In contrast, supportive care does not address the underlying viral infection or liver inflammation, and simply monitoring the condition without intervention would not be appropriate given the elevated ALT levels. The option of adefovir alone is less preferred compared to interferon, particularly in treatment naivety. Finally, stating that no treatment is necessary would be inappropriate, as management is essential for patients who show signs of active disease, indicated by their elevated ALT.
