There are another parameters which are important and you didnt mention: HBcAg, HBS Ab and HBV ELISA... But knowing what you said your mother has more chronic than acute viral Hepatitis
B infection(6% of worlds population has it). It means that she is infected but laboratory parameters are very good and there is no liver complications. Does she have any symptoms such as fatigue, jaundice, right abdominal pain
, weight loss? If does she should do ultrasound and liver biopsy
. So what about treatment? there is a vaccination
but this is not useful anymore for your mother. Treatment depends on severity of liver damage
because this infection passes through different phases. There is a very low possibility of liver cirrhosis and cancer development but considering this she should do repeated work ups at least once a year. There is no some specific treatment or cure.There are some antiviral drugs but are not usually used for this condition. She should just listen to her symptoms, follow some hepatic dietary recommendations and take natural substances which strengthen our immunology system.
Wish you good health, Dr. Ivan Romic (Rominho)
