Core Tip

Core tip: In present day, antiviral drugs with higher genotypic barrier to resistance cannot be used for children with chronic hepatitis B since these drugs are not covered by the general health insurance in many countries. Therefore, lamivudine (LAM) which is not used for adults due to its many drawbacks has been used as a first-line of treatment for children out of necessity. Even though long term treatment results with LAM appear to be good, long term treatment increases the possibility of occurrence of resistant strains. These strains which are resistant to LAM could develop cross resistance to other anti-viral agents.
