Little is known about efficacy of switching to tenofovir monotherapy for multidrug-resistant chronic ehpatitis B patients who achieved a complete virological response to entecavir and tenofovir. This study aimed to investigate the efficacy of switching to tenofovir monotherapy for multidrug-resistant chronic hepatitis B patients with undetectable heaptitis B virus DNA while on tenofovir plus entecavir combination therapy.
