A pre-existing case of HBV infection with elevated HBV DNA after COVID-19 pneumonia treatment
Kanzo(2022)
Abstract
The patient presented with fever and appetite loss. Computed tomography (CT) revealed a moderate grade 2 pneumonia. Besides, further blood examination showed his HB antigen as negative, anti-HBs/c antibody as positive, and HBV DNA level as <1.0 LIU/mL. Therefore, he was diagnosed with COVID-19. Administered treatments comprised oxygen inhalation and steroid therapy, including pulses, remdesivir, and baricitinib, which improved pneumonia. Interestingly, one month posttreatment, his HBV DNA level increased to 1.4 LIU/mL, followed by a further increase to 1.7 LIU/Ml, showing an improvement. Tenofovir alafenamide fumarate was thus administered. In clinical practice, immunosuppressive therapy is used for patients with moderate-to-severe COVID-19 pneumonia. However, close attention should also be paid to the elevation of blood HBV DNA levels during and after treatment.
