ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the safety and efficacy of the combined therapy with entecavir (ETV) and adefovir (ADV) in patients with chronic hepatitis B (CHB) who experienced failure of treatment with single or multiple nucleoside analogs, and analyze the factors that affect the patients response to the treatment.</p><p><b>METHODS</b>Forty-five CHB patients who experienced treatment failure with sequential or/and combined nucleoside analogs received the combined therapy with entecavir and adefovir lasting for at least 6 months. The viroloigcal response (VR), biochemical response (BR) and combined response (CR) at 24 and 48 weeks of the treatment were evaluated. Univairante analysis was used to identify the factors that affect the response to the anti-viral therapy.</p><p><b>RESULTS</b>The VR, BR and CR were 67.7%, 77.8% and 57.8% at 24 weeks, as compared to 76.2%, 78.6% and 61.9% at 48 weeks, respectively. The VR differed significantly between patients with a baseline HBV DNA level [lg(copies/ml)] of 3-6 and those with a level over 6 (85.2% vs 40%, Z=-4.796, P=0.037) at 48 weeks. The presence and absence of cirrhosis at the initial treatment significantly affected the BR at 24 weeks (17.1% vs 82.9%, P=0.048) and at 48 weeks (23.8% vs 76.2%, P=0.023).</p><p><b>CONCLUSION</b>Entecavir combined with adefovir is an effective rescue therapy in CHB patients after failure of treatment with nucleoside analogs. Patients with a lower baseline HBV DNA level without cirrhosis may have better response to the combined treatment.</p>
