Head and whole body computed tomography were normal but laboratory examination showed severe hyponatremia, which could be the cause of severe consciousness disturbance. Similar to what is observed in Takotsubo cardiomyopathy, echocardiography revealed a mid–ventricular and apical heart–wall motion, appearing as hypokinesis; in contrast, the basal segment showed preserved features. The left ventricular dysfunction caused the progressive hypotension and cardiogenic shock. Empiric treatment with corticosteroid considering the adrenal insufficiency, mechanical circulatory support with intra–aortic balloon pumping, and proper correction of hyponatremia were effective. The patient was extubated by day 7, leading to full recovery. Additional tests confirmed the diagnosis of autoimmune polyendocrine syndromes type II (Schmidt syndrome) and Addison’s disease. This case shows that adrenal crisis is caused by the vaccine’s stress and autoimmune reaction in specific individuals. Since it is an acute life–threatening emergency, early identification and prompt management is essential.","PeriodicalId":200165,"journal":{"name":"Nihon Kyukyu Igakkai Zasshi","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121223180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The number of severe COVID–19 cases and deaths has increased due to the Delta variant. We aimed to evaluate the clinical characteristics and treatment outcomes of severe COVID–19 patients. Methods: Fifty–three consecutively presenting patients requiring mechanical ventilation for respiratory failure due to COVID–19 were seen at our institution between February 2020 and October 2021. We divided these patients into two groups: 13 patients admitted from July to October 2021 (the Delta period) and 40 patients admitted from February 2020 to June 2021 (the non–Delta period). We retrospectively compared overall survival between these groups (median observation period, 90 days). Results : All patients were unvaccinated. No L452R mutations were detected during the non–Delta period, whereas 10 (77%) such mutations were detected during the Delta period. Patient characteristics (non–Delta vs. Delta) were as follows: age, 68 vs. 56 years (P<0.01); body mass index, 27 vs. 30kg/m2 (P=0.02); P/F ratio (PaO2/FiO2), 136 vs. 80 (P<0.01); and days to hospitalization, 6 vs. 8 days (P=0.03). The 90–day survival rate was lower in the Delta group (71% vs. 37%, P<0.01). Multivariate analysis showed that the Delta variant was an independent unfavorable prognostic factor (hazard ratio 6.35, 95% confidence interval 1.96–20.6). Conclusion : Despite a younger patient age, survival rate was significantly worse in the Delta period.
