Final answer:
Clinical trials have demonstrated that interferon alpha 2b and antivirals like lamivudine are effective treatments for chronic hepatitis B, while interferon combined with protease inhibitors and sofosbuvir is used for hepatitis C.
Step-by-step explanation:
A number of clinical trials have shown interferon alpha 2b and antivirals such as lamivudine, entecavir, adefovir, and telbivudine as effective treatments for patients with chronic hepatitis B infection. These medications can help control the virus, reduce liver inflammation, and improve liver function.
For patients with chronic hepatitis C, treatment typically includes a combination of interferon, protease inhibitors, and other antivirals like the polymerase inhibitor sofosbuvir. Despite these treatments, hepatitis B and C viruses are known for establishing long-term chronic infections due to their ability to evade the immune system and persist in the liver.
