“…Data on the risk of HBV reactivation during COVID-19 are scarce, but those from other sectors (onco-haematological, rheumatological, gastroenterological) [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 ] strongly suggest that all patients, including SARS-CoV-2 RNA-positive, should be screened for markers of HBV infection before starting corticosteroid and / or immunosuppressive treatments. HBsAg-positive patients should earlier start prophylaxis anti-HBV reactivation with high genetic barrier antivirals and continue for at least 12 months after stopping these therapies.…”
