A small percentage of chronic viral hepatitis B is completely curable. Like our usual adult hepatitis B infection, 90% get completely well, just like the common cold, and 15-10% of people become chronic. Another statistic is that 5% of patients with chronic hepatitis B will slowly get better on their own without treatment each year. For example, liver function gradually normalizes, DNA turns negative, and more often than not, surface antigens disappear. So patients who meet the treatment criteria, including those with abnormal transaminases, abnormal liver function, and positive DNA, depending on what drugs are used, about 5% of patients can be completely cured, but it may take a long time, at least 3-5 years, to be completely cured. In general, patients may take the medicine for 3-5 years, and the major triplets become minor triplets, and then they can stop taking the medicine for another three years, but it is not a complete cure. However, there are some patients who are very good when they take the medicine, but when they stop taking the medicine, they will relapse after a while. This part of the patients definitely need long-term treatment, because they will relapse again when they stop taking the medicine, and after a few recurrences, they will develop cirrhosis, which requires long-term treatment and is very difficult to cure completely.
