AIM
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus-specific reverse transcriptase-polymerase chain reaction (RT-PCR) represents the diagnostic gold standard. We explored the value of chest ultrasonography to predict positivity to SARS-CoV-2 on RT-PCR in suspected COVID-19 cases.
PATIENTS & METHODS: Consecutive patients with suspect COVID-19 were included if they had fever and/or history of cough and/or dyspnea. Lung ultrasound score (LUSS) was computed according to published methods.
RESULTS
A total of 76 patients were included. A 3-variable model based on aspartate transaminase (AST) > upper limit of normal, LUSS >12 and body temperature >37.5°C yielded an overall accuracy of 91%.
CONCLUSION
A simple LUSS-based model may represent a powerful tool for initial assessment in suspected cases of COVID-19.
目的
严重急性呼吸综合征冠状病毒2（SARS-CoV-2）病毒特异性逆转录聚合酶链反应（RT-PCR）是诊断的金标准。我们探讨了胸部超声检查在疑似新型冠状病毒肺炎（COVID-19）病例中预测RT-PCR检测SARS-CoV-2阳性的价值。
患者与方法
纳入连续的疑似COVID-19患者，这些患者有发热和/或咳嗽病史和/或呼吸困难。根据已发表的方法计算肺部超声评分（LUSS）。
结果
共纳入76例患者。基于天冬氨酸转氨酶（AST）>正常上限、LUSS>12和体温>37.5°C的三变量模型总体准确率为91%。
结论
一个简单的基于LUSS的模型可能是疑似COVID-19病例初始评估的有力工具。
