Recommendations and potential future options in the treatment of hepatitis B

The natural history of chronic hepatitis B should be clearly defined before appropriate recommendations for treatment can be advocated. In patients who acquire the disease in early life, the complications of chronic hepatitis B continue to occur as a result of prolonged insidious damage to the liver, even in the low viraemic phase. Treatment that ends with hepatitis B e antigen seroconversion with hepatitis B virus DNA levels just below 10(5) copies/ml may not be sufficient. Patients with mild elevation of alanine aminotransferase levels are already at considerable risk of developing complications. Treatment strategy should aim at maximal and prolonged viral suppression to the lowest possible hepatitis B virus DNA levels. Nucleotide/nucleoside analogues will become the mainstay of treatment. Future treatment strategic plans should target maximising antiviral potency and minimising the chance of drug resistance.
