Case reportDirect-acting antiviral treatment in adults infected with hepatitis C virus: Reactivation of hepatitis B virus coinfection as a further challenge
Section snippets
Why this case is important?
Use of direct-acting antiviral drugs (DAAs) greatly improves management of adults infected with hepatitis C virus (HCV), whether patients are treatment-naive or unsuccessfully pre-treated [1].
Several inhibitors of viral nonstructural proteins (NS3/4A protease, NS5A and NS5B polymerase), allow a rapid HCV clearance and increase rates of sustained virological response. Treatments incorporating only DAAs have superseded most previous regimens containing peginterferon and ribavirin [1].
Recently,
Case description
A HCV/HIV-coinfected 53-year-old man followed since 1988 in the Infectious Diseases Department of the Nice University Hospital presented for re-treatment of HCV genotype 4d infection. He was previously null responder to a bi-therapy incorporating peginterferon and ribavirin. Although liver stiffness was low (transient elastography using FibroScan = 7 kPa), HCV treatment was reconsidered because of cutaneous porphyria. Furthermore, his HIV infection (CDC class C3) was controlled since 2011, with a
Similar and contrasting cases in the literature
Reactivation of hepatitis B is characterized by an abrupt reappearance or rise of HBV DNA levels in the serum of a patient with previously resolved or inactive HBV infection. This increase of HBV replication, or “viral breakthrough”, is often accompanied by a “biochemical breakthrough”, i.e. reappearance of disease activity or a flare of hepatitis in previously inactive or minimal disease [7]. To our knowledge, four cases of HBV reactivation have just been reported in patients infected with
Discussion
Due to their transmission route, triple HCV/HBV/HIV infection can concern the same person. We reported herein HBV reactivation after initiation of DAAs regimen in a HCV genotype 4d/HIV coinfected patient having resolved HBV infection. The typical course of HBV reactivation was observed, with first viral breakthrough and then hepatitis cytolysis induced by the anti-HBV specific immune response (Fig. 1). In HBV/HIV-coinfected patient, HBV reactivation is known because of progressive
