An update on the treatment options for HBV/HCV coinfection

Despite the reciprocal inhibition exerted by HBV and HCV genomes, dual HBV/HCV infection is associated with more severe forms of liver disease and warrant effective treatment. Areas covered: A careful evaluation of disease progression to establish the predominance of one virus over another, concomitant HIV infection and comorbidities is essential to make the best therapy choices. In most virological conditions interferon (IFN)-based treatment has been replaced by a combination of different classes of second generation directly acting antivirals (DAAs), which offer better tolerability and HCV eradication in 95% of cases. Tenofovir or entecavir should be part of treatment for patients with active HBV production, for those coinfected with HIV and for those with cirrhosis. Expert opinion: DAAs have been successfully used to eradicate HCV infection in recent years, but the high cost may limit their use particularly in developing countries. Entecavir and tenofovir have been demonstrated to be effective for long-term inhibition of HBV replication. Careful monitoring of serum ALT and markers of HBV and HCV replication before and during treatment is essential for an early diagnosis and treatment of virus reactivation.
