近日,中國武漢金銀潭醫院張麗聯合上海交通大學瑞金醫院張欣欣課題組研究了武漢市99例2019新型冠狀病毒肺炎的流行病學及臨床特徵。相關論文於2020年1月30日發表於國際頂尖學術期刊《柳葉刀》雜誌上。
2019年12月,中國武漢出現2019年新型冠狀病毒(2019-nCoV)相關肺炎。
為了進一步闡明2019-nCoV肺炎的流行病學和臨床特徵,研究組進行了一項回顧性的單中心研究。他們納入了武漢市金銀潭醫院從2020年1月1日至1月20日間收治的所有2019-nCoV確診病例。病例經實時RT-PCR證實,並進行流行病學、人口學、臨床和放射學特徵及實驗室數據分析。
在99名2019-nCoV肺炎患者中,49名(49%)曾接觸過華南海鮮市場。患者平均年齡為55.5歲,其中男性67例,女性32例。所有患者均經實時RT-PCR檢測到2019-nCoV。50例(51%)合併慢性病。
患者有發熱(83%)、咳嗽(82%)、呼吸急促(31%)、肌肉疼痛(11%)、精神錯亂(9%)、頭痛(8%)、咽喉痛(5%)、流涕(4%)、胸痛(2%)、腹瀉(2%)和噁心嘔吐(1%)等臨床表現。
影像學檢查,74例(75%)表現為雙側肺炎,14例(14%)表現為多發斑點和磨玻璃樣影,1例(1%)表現為氣胸。17例(17%)出現急性呼吸窘迫症候群,其中11例(11%)短時間內病情加重,死於多器官衰竭。
2019-nCoV感染呈聚集性發病,有合併症的老年男性更易感染,並可導致嚴重甚至致命性的呼吸系統疾病,如急性呼吸窘迫症候群。一般來說,死亡患者的特徵與MuLBSTA評分一致,MuLBSTA評分是預測病毒性肺炎死亡率的早期預警模型。仍需進一步研究,以探討MuLBSTA評分在預測2019-nCoV感染死亡風險中的適用性。

Abstract:
Background
In December, 2019, a pneumonia associated with the 2019 novel coronavirus (2019-nCoV) emerged in Wuhan, China. We aimed to further clarify the epidemiological and clinical characteristics of 2019-nCoV pneumonia.
Methods
In this retrospective, single-centre study, we included all confirmed cases of 2019-nCoV in Wuhan Jinyintan Hospital from Jan 1 to Jan 20, 2020. Cases were confirmed by real-time RT-PCR and were analysed for epidemiological, demographic, clinical, and radiological features and laboratory data. Outcomes were followed up until Jan 25, 2020.
Findings
Of the 99 patients with 2019-nCoV pneumonia, 49 (49%) had a history of exposure to the Huanan seafood market. The average age of the patients was 55·5 years (SD 13·1), including 67 men and 32 women. 2019-nCoV was detected in all patients by real-time RT-PCR. 50 (51%) patients had chronic diseases. Patients had clinical manifestations of fever (82 [83%] patients), cough (81 [82%] patients), shortness of breath (31 [31%] patients), muscle ache (11 [11%] patients), confusion (nine [9%] patients), headache (eight [8%] patients), sore throat (five [5%] patients), rhinorrhoea (four [4%] patients), chest pain (two [2%] patients), diarrhoea (two [2%] patients), and nausea and vomiting (one [1%] patient). According to imaging examination, 74 (75%) patients showed bilateral pneumonia, 14 (14%) patients showed multiple mottling and ground-glass opacity, and one (1%) patient had pneumothorax. 17 (17%) patients developed acute respiratory distress syndrome and, among them, 11 (11%) patients worsened in a short period of time and died of multiple organ failure.
Interpretation
The 2019-nCoV infection was of clustering onset, is more likely to affect older males with comorbidities, and can result in severe and even fatal respiratory diseases such as acute respiratory distress syndrome. In general, characteristics of patients who died were in line with the MuLBSTA score, an early warning model for predicting mortality in viral pneumonia. Further investigation is needed to explore the applicability of the MuLBSTA score in predicting the risk of mortality in 2019-nCoV infection.
