KRT88P and chronic hepatitis C virus infection: We herein reported a rare case of HBV reactivation from resolved infection status (HBsAg-, anti-HBs-negative, anti-HBc-positive) that developed after DAA treatment in a patient with chronic hepatitis C. This case highlights that reactivation of resolved HBV infection remains a risk following eradication of HCV, suggesting that HCV infection may play a role in suppressing HBV replication.
