To report the methods and findings of two complete autopsies of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive individuals who died in Oklahoma (United States) in March 2020.
Complete postmortem examinations were performed according to standard procedures in a negative-pressure autopsy suite/isolation room using personal protective equipment, including N95 masks, eye protection, and gowns. The diagnosis of coronavirus disease 2019 (COVID-19) was confirmed by real-time reverse transcriptase polymerase chain reaction testing on postmortem swabs.
A 77-year-old obese man with a history of hypertension, splenectomy, and 6 days of fever and chills died while being transported for medical care. He tested positive for SARS-CoV-2 on postmortem nasopharyngeal and lung parenchymal swabs. Autopsy revealed diffuse alveolar damage and chronic inflammation and edema in the bronchial mucosa. A 42-year-old obese man with a history of myotonic dystrophy developed abdominal pain followed by fever, shortness of breath, and cough. Postmortem nasopharyngeal swab was positive for SARS-CoV-2; lung parenchymal swabs were negative. Autopsy showed acute bronchopneumonia with evidence of aspiration. Neither autopsy revealed viral inclusions, mucus plugging in airways, eosinophils, or myocarditis.
SARS-CoV-2 testing can be performed at autopsy. Autopsy findings such as diffuse alveolar damage and airway inflammation reflect true virus-related pathology; other findings represent superimposed or unrelated processes.
报告 2020 年 3 月在美国俄克拉荷马州死亡的 2 例严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)阳性个体的尸检方法和结果。
按照负压解剖室/隔离室的标准程序,使用包括 N95 口罩、眼部防护和长袍在内的个人防护设备进行完整的尸检。通过对死后拭子进行实时逆转录聚合酶链反应检测,确诊 2019 年冠状病毒病(COVID-19)。
1 例 77 岁肥胖男性,有高血压、脾切除术病史,发热、寒战 6 天,在转运途中死亡。死后鼻咽和肺实质拭子均检测到 SARS-CoV-2 阳性。尸检显示弥漫性肺泡损伤和支气管黏膜的慢性炎症和水肿。1 例 42 岁肥胖男性,有肌强直性营养不良病史,出现腹痛,随后发热、呼吸急促和咳嗽。死后鼻咽拭子 SARS-CoV-2 阳性;肺实质拭子阴性。尸检显示急性支气管肺炎,有吸入证据。尸检均未发现病毒包涵体、气道黏液栓、嗜酸性粒细胞或心肌炎。
尸检时可进行 SARS-CoV-2 检测。弥漫性肺泡损伤和气道炎症等尸检发现反映了真正与病毒相关的病理学;其他发现代表了叠加或不相关的过程。
