REGN-COV2 antibody cocktail in patients with SARS-CoV-2: Observational study from a single institution in Japan.

INTRODUCTION: A new treatment for coronavirus disease (COVID-19), REGN-COV2, a cocktail consisting of two neutralizing antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been approved for patients at a risk of developing more severe disease. METHODS: We retrospectively reviewed patients recently diagnosed with COVID-19 with risk factors for severe infection, who were treated with the REGN-COV2 antibody cocktail between July and September 2021. The REGN-COV2 antibody cocktail was administered to patients within 7 days of disease onset, with an oxygen saturation of >93%, and with at least one comorbidity. We investigated the percentage of patients with COVID-19-related hospitalization or death, the duration of symptoms after treatment, and the adverse effects of treatment. RESULTS: A total of 108 patients were reviewed. Of them, 64% were aged ≥50 years, 31% had obesity, 36% had hypertension, and 18% had diabetes. In addition, 49% had multiple risk factors for severe COVID-19. Overall, 12 patients (11%) needed COVID-19-related hospitalization. No adverse effects of treatment were observed. CONCLUSIONS: This study shows that treatment with the REGN-COV2 antibody cocktail is safe and beneficial in patients at a risk of developing severe COVID-19.

Psychological Effects on Healthcare Workers during the COVID-19 Outbreak: A Single-center Study at a Tertiary Hospital in Tokyo, Japan.

Objective The present study analyzed the psychological status of healthcare workers in Japan and the influencing factors during the 2019 coronavirus disease pandemic. Methods An online survey was conducted from July 22 to August 21, 2020. A total of 328 of the 1,029 medical staff members in our university hospital participated in the study. Their mental health was assessed using the 12-item General Health Questionnaire. A multivariate regression analysis was performed to identify the factors associated with the mental health outcomes. Results Of the respondents, 78.0% reported psychological distress. Overall, we found that women, non-physicians, those who lived alone, and younger respondents had significantly greater psychological distress than their counterparts. The multivariate regression analysis showed that four factors were extracted as independent 12-item General Health Questionnaire-related factors: the lack of a sense of mission as a medical professional, the burden of the change in the quality of work, the lack of understanding about virus infectivity, and a strong sense of duty. Conclusion In summary, we found a high prevalence of psychological distress among healthcare workers during the 2019 coronavirus disease outbreak in Japan. Independent risk factors for psychological distress were the burden of the change in the quality of work, the lack of understanding about virus infectivity, a sense of responsibility, and the lack of a strong motivation and drive to help.
