Adefovir for lamivudine resistant HBV: More than meets the eye

subject

description

– In patients with LAM resistance and high levels of HBV-DNA, especially if HBeAg positive, it may be difficult to obtain a strong virological suppression with ADV. – Restrictive criteria are needed to define virological response (HBV-DNA < 10 3 copies/ml or 200 IU/ml). – Early finding of non-response or of suboptimal response after 9–12 months of ADV therapy suggests a high risk of emergence of ADV-resistant strains and should prompt a change of treatment strategy. In patients with cirrhosis, due to the risk of liver failure, treatment changes should be considered even earlier, at 3–6 months.
