ObjectivesCOVID-19 infection demonstrates characteristic findings in chest CT. The optimal timing of repeated CT scans still needs to be clarified, and the optimal time to assess imaging clearance in COVID-19 is still unknown. It is crucial to have a roadmap of the imaging course of COVID-19 pneumonia to develop guidelines for prompt diagnosis of pulmonary complications, especially fibrosis, at the earliest stage.PurposeTo assess the temporal changes of chest CT findings in patients with COVID-19 pneumonia and evaluate the rate of a complete resolution and determine the patients are at excessive risk for residual parenchymal abnormalities.Materials and MethodsThis retrospective observational study included 48 patients with real-time polymerase chain reaction–confirmed COVID-19 who were admitted to three academic hospitals. These patients underwent at least one initial chest CT before or after admission and at least one follow-up CT scan four weeks or more after the onset of the symptoms. All chest CTs were categorized according to time of performance into four groups, including the first week, second week, third-fourth week, and more than 28 days. Lung involvement was categorized as predominantly alveolar (ground-glass opacity and consolidation), organizing pneumonia, and reticular patterns. The severity of involvement was also evaluated by the reader.ResultsForty-eight patients and a total of 130 chest CT scans were evaluated. The alveolar pattern showed a gradual decrease in frequency from 91% in the first week to 9% after the fourth week of the disease but the organizing pneumonia pattern gradually increased with disease progression and the frequency of reticular pattern increased significantly after third week. Complete resolution of CT findings was seen in 17 patients (13.1%) and was significantly more prevalent in patients of younger age (p value<0.001) and with lower initial CT severity scores (p value=0.048). CT severity scores in the second week were significantly higher in ICU admitted patients (p value=0.003).ConclusionThere are temporal patterns of lung abnormalities in patients with COVID-19 pneumonia. The predominant CT pattern was alveolar infiltrate in the first and second weeks of the disease, replaced with an organizing pneumonia pattern in the third and fourth weeks. Progression of lung involvement was correlated with ICU admission due to the highest CT severity score in the second and third weeks of presentation but not in the first week in patients who were admitted at ICU. Complete CT resolution was significantly more common in patients of younger age and lower initial CT severity scores. 相似文献

Background Blood procalcitonin (PCT) levels usually increase during infectious diseases and might be helpful to differentiate bacterial from non-bacterial origin. COVID-19 patients could present co-infections at initial presentation in the Emergency Department and nosocomial infections during stay in the ICU. However, the published literature has not established whether PCT changes could aid in the diagnosis of infectious complication during the COVID-19 pandemic. Methods Retrospective, single-center, cohort study, including COVID-19 patients admitted between March and May 2020. The data were prospectively collected for department purposes; laboratory results were collected automatically at admission and during the whole patient admission. Results 56 patients were analyzed (female 32%, male 68%), 35 were admitted to ICU, and 21 received general ward care. 21 ICU patients underwent mechanical ventilation (88%), and 9 died during admission (26%). Non-survivors had higher initial blood PCT levels than survivors at ICU admission (p. 相似文献

BACKGROUNDLung transplantation is considered an effective method for treating patients with end-stage coronavirus disease 2019 (COVID-19). The nurses play a pivotal role in lung transplantation for COVID-19 patients.CASE SUMMARYTwo elderly patients were admitted to the emergency department due to cough, and the nucleic acid test was positive. The patients were preliminarily diagnosed with COVID-19. The chest computed tomography scan revealed massive lung consolidation, and the patients did not improve after treatment with antiviral drugs, glucocorticoids, antibiotics, and other drugs. Under the support of pure oxygen in extracorporeal membrane oxygenation, the patients’ oxygen levels were still poor, indicating that they were in the terminal stage of viral pneumonia. The patients underwent double-lung transplantation and received intraoperative care. The extracorporeal membrane oxygenation device was removed within a week of the surgical procedure, and the respiratory circulation of the patients were stabilized.CONCLUSIONHigh-quality care for COVID-19 patients undergoing lung transplantation ensures patient safety during operation while protecting the safety of the medical staff. 相似文献

新型冠状病毒肺炎(COVID-19)的疫情引发了全世界的关注。早期诊断对COVID-19的治疗、患者预后尤为关键。临床检验中发现早期的COVID-19患者核酸检测多次呈假阴性,特别是不同时间多次阴性结果后转为阳性,给临床诊断和疾病控制带来极大困扰。该文立足于疫情的早日防控,从临床、检验的不同视角,从标本采集、检测方法、产品稳定性等多方面剖析产生假阴性的可能原因,并且结合临床实践和检测技术,从整合特异性实验室指标,规范标本采集方式和过程,严格检测试剂的监管和审批等方面提出行之有效的方案,旨在为切实降低检测假阴性或假阳性率提供临床参考,为COVID-19临床准确诊断及疫情防控提供有力支撑。 相似文献

目的分析新型冠状病毒肺炎(COVID-19)患者的临床特征,探讨与住院中期胸部CT表现严重程度有关的影响因素。方法回顾性收集2020年1月28日至3月15日收治具有完整临床资料、住院第6~10天的胸部CT(住院中期胸部CT)及实验室检查结果的COVID-19患者40例。依据胸部CT表现所示肺内病灶及其累及范围,将患者分为胸部CT轻度组(19例)和胸部CT重度组(21例)。采用多因素Logistic回归分析住院中期胸部CT表现严重程度的影响因素。结果两组患者性别构成、暴露史、合并并发症、发病至入院时间、临床症状、实验室检查指标、入院时病情分型差异均无统计学意义(P>0.05)。胸部CT重度组患者住院时间较胸部CT轻度组偏长,差异有统计学意义(P<0.05)。多因素Logistic回归分析显示,与胸部CT轻度组相比,男性、合并并发症更容易造成COVID-19患者住院中期胸部CT重度表现(P<0.05),并且胸部CT重度组患者年龄偏大,病毒排毒时间更长(P<0.05)。结论与住院中期胸部CT轻度组相比,胸部CT重度组男性、合并并发症比例更高,且年龄偏大,病毒排毒时间更长。结合胸部CT的优势特点,可以应用胸部CT辅助临床对COVID-19患者进行更加科学精准的防控。 相似文献
