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.

OBJECTIVE: The aim of this study was to investigate the epidemiology of post-COVID conditions beyond 12 months and identify factors associated with the persistence of each condition. STUDY DESIGN: This was a cross-sectional questionnaire-based survey. METHODS: We conducted the survey among patients who had recovered from COVID-19 and visited our institute between February 2020 and November 2021. Demographic and clinical data and data regarding the presence and duration of post-COVID conditions were obtained. We identified factors associated with the persistence of post-COVID conditions using multivariable linear regression analyses. RESULTS: Of 1148 surveyed patients, 502 completed the survey (response rate, 43.7%). Of these, 393 patients (86.4%) had mild disease in the acute phase. The proportion of participants with at least one symptom at 6, 12, 18, and 24 months after symptom onset or COVID-19 diagnosis was 32.3% (124/384), 30.5% (71/233), 25.8% (24/93), and 33.3% (2/6), respectively. The observed associations were as follows: fatigue persistence with moderate or severe COVID-19 (ß = 0.53, 95% confidence interval [CI] = 0.06-0.99); shortness of breath with moderate or severe COVID-19 (ß = 1.39, 95% CI = 0.91-1.87); cough with moderate or severe COVID-19 (ß = 0.84, 95% CI = 0.40-1.29); dysosmia with being female (ß = -0.57, 95% CI = -0.97 to -0.18) and absence of underlying medical conditions (ß = -0.43, 95% CI = -0.82 to -0.05); hair loss with being female (ß = -0.61, 95% CI = -1.00 to -0.22), absence of underlying medical conditions (ß = -0.42, 95% CI = -0.80 to 0.04), and moderate or severe COVID-19 (ß = 0.97, 95% CI = 0.41-1.54); depressed mood with younger age (ß = -0.02, 95% CI = -0.04 to -0.004); and loss of concentration with being female (ß = -0.51, 95% CI = -0.94 to -0.09). CONCLUSIONS: More than one-fourth of patients after recovery from COVID-19, most of whom had had mild disease in the acute phase, had at least one symptom at 6, 12, 18, and 24 months after onset of COVID-19, indicating that not a few patients with COVID-19 suffer from long-term residual symptoms, even in mild cases.

OBJECTIVES: To investigate the prevalence of post coronavirus disease (COVID-19) condition of the Omicron variant in comparison to other strains. STUDY DESIGN: A single-center cross-sectional study. METHODS: Patients who recovered from Omicron COVID-19 infection (Omicron group) were interviewed via telephone, and patients infected with other strains (control group) were surveyed via a self-reporting questionnaire. Data on patients' characteristics, information regarding the acute-phase COVID-19, as well as presence and duration of COVID-19-related symptoms were obtained. Post COVID-19 condition in this study was defined as a symptom that lasted for at least 2 months, within 3 months of COVID-19 onset. We investigated and compared the prevalence of post COVID-19 condition in both groups after performing propensity score matching. RESULTS: We conducted interviews for 53 out of 128 patients with Omicron and obtained 502 responses in the control group. After matching cases with controls, 18 patients from both groups had improved covariate balance of the factors: older adult, female sex, obesity, and vaccination status. There were no significant differences in the prevalence of each post COVID-19 condition between the two groups. The number of patients with at least one post COVID-19 condition in the Omicron and control groups were 1 (5.6%) and 10 (55.6%) (p = 0.003), respectively. CONCLUSIONS: The prevalence of post Omicron COVID-19 conditions was less than that of the other strains. Further research with a larger sample size is needed to investigate the precise epidemiology of post COVID-19 condition of Omicron, and its impact on health-related quality of life and social productivity.
