Background and Aim: Immunosuppressive agents (e.g., baricitinib [BAR], tricizumab [TCZ]) and steroids are used for treating coronavirus disease 2019 (COVID-19) pneumonia. These immunosuppressive agents are known to cause HBV reactivation. The current guidelines recommend HBV screening and HBV reactivation monitoring in Japan. However, the status of compliance among treated patients with COVID-19 pneumonia remains unclear. Herein, we report the status of compliance with the current guidelines on HBV reactivation. Method(s): We investigated the implementation of HBV screening and HBV reactivation monitoring for patients who received immunosuppressive agents in our hospital from April 2021 up to June 2021. Background factors related to the presence or absence of screening were analyzed. Result(s): There were 123 patients who received immunosuppressive agents in our hospital from April 2021 up to June 2021. The patients median age was 63 years old (31-95 years), and 90 patients were men. BAR/steroid therapy was given in 115 patients and TCZ/steroid therapy in 8 patients. Of the 123 patients in whom HBs antigen level was measured, 2 patients were positive for HBs antigen. Anti-HBc/ HBs antibodies were measured in all 121 HBsAg-negative patients according to the guidelines. Of 32 patients who were positive for either or both anti-HBc/HBs antibodies, HBV DNA was measured in 31 patients. Of 34 patients who required regular reactivation monitoring, 30 did not receive regular monitoring (6 died in the hospital, 11 were transferred to other hospitals, and 13 were terminated of their treatment early in the outpatient department of the hospital). Only 4 patients were monitored according to the guidelines. Of the 4 patients monitored, 1 was positive for HBs antigen and was given a nucleic acid analogue. In 1 patient, HBV DNA increased from signal-positive to 1.4 LIU/mL and then to 1.7 LIU/mL and nucleic acid analogue was started. The remaining 2 patients had undetectable HBV DNA or remained signal-positive. Conclusion(s): The HBV reactivation monitoring rate at the start of COVID-19 pneumonia treatment was high. However, HBV reactivation monitoring after the COVID-19 pneumonia treatment was difficult because most patients were transferred to other hospitals or had their treatment terminated.
