Key clinical message:
Vasculitis, though rare, is a serious extrahepatic manifestation of HBV
infection.Chronic HBV affects millions of people globally, causing
significant morbidity and 600,000 deaths annually. HBV patients should
be considered for evaluation of vasculitis, even if they lack liver
symptoms. Steroid therapy has been found effective for vasculitis in HBV
patients and is more beneficial when combined with antiviral treatment.
