Hepatitis B virus DNA and RNA persist in liver after serologic recovery in persons with hepatitis C virus.

After recovery from a hepatitis B virus (HBV) infection, reactivation can occur with immunosuppression; thus, it is assumed that replication competent HBV persists in the liver. We sought to detect persistent HBV from 13 people with spontaneous recovery. We quantified HBV DNA and RNA in core liver biopsies (median 1.72x106 cells) from people who inject drugs (PWID). Among 13 biopsies, 8 (61%) had evidence of HBV DNA or RNA and 5 (38%) had both HBV DNA and RNA. mRNAs derived from cccDNA and integrated HBV DNA. Here, we show prevalent HBV DNA and RNA despite clinical recovery in PWID. We used a sensitive method to determine the amount of hepatitis B virus DNA or RNA in the livers of 13 individuals who recovered from hepatitis B virus infection. We found viral DNA or RNA in the liver in 61% of individuals despite no detectable virus in blood. Our findings support that eliminating all hepatitis B from the liver is a difficult treatment goal.
