Patient: Male, 73-year-old Final Diagnosis: Severe COVID-19 pneumonia complicated by right atrium thrombus Symptoms: Fever • dyspnea • cough Medication:— Clinical Procedure: — Specialty: Critical Care Medicine Objective: Educational purpose Background: Recent studies demonstrated evidence of coagulation dysfunction in hospitalized patients with severe coronavirus disease 2019 (COVID-19) due to excessive inflammation, hypoxia, platelet activation, endothelial dysfunction, and stasis. Effective anticoagulation therapy may play a dominant role in the management of severe COVID-19 cases. Case Report: A 73-year-old man with a 6-day history of fever up to 38.5°C, dyspnea, cough, and fatigue was diagnosed with COVID-19. He had a past medical history significant for hypertension and coronary artery bypass grafting. Two days after hospital admission, the patient developed acute respiratory failure, requiring intubation, mechanical ventilation, and transfer to the intensive care unit (ICU). He received treatment including antibiotics, hydroxychloroquine, tocilizumab, vasopressors, prone positioning, and anticoagulation with enoxaparin at a prophylactic dose. After a 15-day ICU stay, the patient was hemodynamically stable but still hypoxemic; a transthoracic echocardiogram at that time, followed by a transesophageal echocardiogram for better evaluation, revealed the presence of a right atrium thrombus without signs of acute right ventricular dilatation and impaired systolic function. Since the patient was hemodynamically stable, we decided to treat him with conventional anticoagulation under close monitoring for signs of hemodynamic deterioration; thus, the prophylactic dose of enoxaparin was replaced by therapeutic dosing, which was a key component of the patient’s successful outcome. Over the next few days he showed significant clinical improvement. The follow-up transesophageal echo-cardiogram 3 weeks after effective therapeutic anticoagulation revealed no signs of right heart thrombus. Conclusions: The presented COVID-19 case, one of the first reported cases with evidence of right heart thrombus by transesophageal echocardiography, highlights the central role of diagnostic imaging strategies and the importance of adequate anticoagulation therapy in the management of severe COVID-19 cases in the ICU.
e21624 Background: As shown in recent studies, inflammation plays a key role in lung cancer (LC) pathogenesis and evolution, while the potential prognostic and predictive value of various inflammation markers in different disease stages is being extensively studied. We herein aimed to further evaluate the potential prognostic value of a new inflammation marker (ALI, Advanced Lung Cancer Inflammation Index = BMI x Alb / NLR), which combines previous markers of systematic inflammation with markers of nutrition or cachexia at the time of LC diagnosis. Methods: The medical records of 67 patients, diagnosed with LC in Sismanoglio Athens General hospital, within a two-year period (January 2016-January 2017) were retrospectively studied. Demographic, clinicopathological and laboratory features of patients, including pre-treatment ALI, were recorded and correlated with prognosis (overall survival, OS). Results: A total of 67 patients were included with a mean age of 60 (± 8) years. The majority of cases were men (39/67,58.2 %), with positive smoking history (62/67, 92.5%), performance status (PS) 1-2 (43/67, 64.2%) and disease stage IV (54/67, 80.6%). Adenocarcinoma was the commonest histological type observed (19/67, 28.5%). Values of ALI ranged from 7.8 to 37.2 (mean: 21±6). The cut-off point of ALI was 19 (based on ROC curve analysis) and patients were divided into two groups: those with ALI < 19 and those with ALI ≥ 19. In univariate analysis, PS and the presence of metastatic disease, as well as ALI values < 19, were all correlated with reduced survival (p = 0.002, p = 0.028 and p = 0.018, respectively). In multivariate analysis, PS was the only parameter that retained its statistically significant correlation with an adverse prognosis (p = 0.048), although its prognostic significance was increased when combined with ALI. Conclusions: Although failing to confirm an independent prognostic value for ALI, the results of our study suggest that combination of ALI with standard prognostic predictors such as PS may improve prediction of patients’ survival. Additional prospective studies are warranted to validate the prognostic significance of this promising biomarker and expand its use in routine practice.
