目的 分析毕节地区新型冠状病毒(2019-nCoV)肺炎(novel coronavirus pneumonia,NCP)胸部CT影像学表现,探讨对NCP的临床诊断的价值。方法 回顾性分析毕节市第三人民医院2020年1月14日至2月18日收治的13例NCP患者的流行病学特征及胸部CT影像学特征。结果 13例患者中2例为长期居住在武汉来毕;1例由从上海到湖北宜昌逗留3天返毕;1例直接与武汉当地人接触;3例为与确诊病人的密切接触者;5例是聚集性发病,均与从浙江省台州市返毕确诊病人密切接触;1例无流行病学史。胸部CT影像学以双肺或一侧肺散在斑片状、磨玻璃状高密度影,密度不均,边界不清,肺野外带显著为特征。重型患者短期内肺部CT影像学变化明显。结论 确诊NCP普通型患者胸部CT影像学大多以典型表现为特征;重型NCP患者短时间内可出现实变及肺纤维化。

Objective To analyze the novel coronavirus (2019-nCoV) novel coronavirus pneumonia (NCP) chest CT imaging findings in Bijie area, and to explore the clinical diagnostic value of NCP. Methods The epidemiological characteristics and chest CT features of 13 NCP patients admitted to The Third People's Hospital of Bijie from January 14 to February 18, 2020 were analyzed retrospectively. Results Among the 13 patients, 2 lived in Wuhan for a long time, 1 stayed for 3 days from Shanghai to Yichang, Hubei, and returned home; 1 directly contacted with the local people in Wuhan; 3 closely contacted with the confirmed patients; 5 were clustered diseases, all closely contacted with the confirmed patients returning from Taizhou, Zhejiang province; 1 had no epidemiological history. CT imaging of the chest is characterized by patchy, ground glass high-density shadows scattered in two or one side of the lung, with uneven density, unclear boundary and significant lung field zone. Conclusion Most of the chest CT images of the patients with NCP were characterized by typical manifestations, while consolidation and pulmonary fibrosis were found in the patients with severe NCP in a short period of time.

目的 探讨特发性肺纤维化(IPF)患者和结缔组织病相关性纤维化间质性肺疾病(CTD-fILD)患者急性加重(AE)的短期内死亡的危险因素。方法 回顾性分析2017年10月—2019年9月在深圳大学和广州医科大学附属第一医院住院的25例 AE-CTD-fILD和26例AE-IPF患者临床信息,Kaplan-Merier法对两组患者进行生存分析,Cox回顾分析年龄、性别、吸烟、白细胞总数、C反应蛋白、红细胞沉降率及肿瘤指标在急性加重患者死亡中的作用。结果 与AE-CTD-fILD比较,AE-IPF患者组男性比例、年龄、吸烟比例较高,红细胞沉降率较低(24/26 vs 10/25,P<0.001;63.77±9.97 vs 58.00±10.32,P=0.048;16/26 vs 9/25,P=0.02;28.07±29.45 vs 64.35±40.34,P=0.002 );90天内,26例AE-IPF患者11例死亡,25例AE-CTD-fILD患者5例死亡,死亡率无明显差异(42.3% vs 20%,P=0.073);Cox回归分析显示,白细胞计数是AE-IPF和AE-CTD-fILD患者的死亡危险因素(HR=1.305,P=0.001;HR=1.529,P=0.009);CA15-3是AE-IPF患者死亡危险因素(HR=1.015,P=0.005)。结论 急性加重IPF和CTD-fILD患者短期内死亡风险相似,白细胞计数及外周CA15-3水平可能是肺纤维化急性加重患者短期内死亡的危险因素。

Objective To explore the risk factors for acute exacerbation (AE) in patients with idiopathic pulmonary fibrosis (IPF) and connective tissue disease associated with fibrotic interstitial lung disease (CTD-fILD). Methods We retrospectively reviewed 25 patients with AE-CTD-fILD and 26 patients with AE-IPF, and Kaplan-Merier was used to analyze the survival of the two groups of patients. The impact of age,gender, smoking,WBC,CRP,ESR and tumor markers on acute exacerbation death were performed by Cox regression analysis. Results The AE-IPF patients had a higher proportion of men,age and smoking,and a lower ESR compared with AE-CTD-fILD patients(24/26 vs 10/25,P<0.001;63.77±9.97 vs 58.00±10.32,P=0.048;16/26 vs 9/25,P=0.02;28.07±29.45 vs 64.35±40.34,P=0.002 ). 11 cases of 26 patients with AE-IPF and 5 cases of 25 patients with AE-CTD-fILD died within 90 days, Log-rank tests showed patients with CTD-fILD had similar mortality rate compared with IPF patients after AE(42.3% vs 20%,P=0.073). The WBC count was negatively correlated with survival and the independent predictors for patients with AE-IPF and AE-CTD-fILD after adjusting for other clinical variates in Cox regression models(HR=1.305,P=0.001;HR=1.529,P=0.009). CA15-3 may be a risk factor for death of AE-IPF patients(HR=1.015,P=0.005). Conclusion AE-CTD-fILD and AE-IPF were associated with similar poor short-term survival, WBC count and plasma CA15-3 may be the independent survival predictors respectively for patients with acute exacerbation of pulmonary fibrosis in short term.
