Modified SCOPE (mSCOPE) Score as a Tool to Predict Mortality in COVID-19 Critically Ill Patients.

INTRODUCTION: Efficient clinical scores predicting the outcome of severe COVID-19 pneumonia may play a pivotal role in patients' management. The aim of this study was to assess the modified Severe COvid Prediction Estimate score (mSCOPE) index as a predictor of mortality in patients admitted to the ICU due to severe COVID-19 pneumonia. MATERIALS AND METHODS: In this retrospective observational study, 268 critically ill COVID-19 patients were included. Demographic and laboratory characteristics, comorbidities, disease severity, and outcome were retrieved from the electronical medical files. The mSCOPE was also calculated. RESULTS: An amount of 70 (26.1%) of patients died in the ICU. These patients had higher mSCOPE score compared to patients who survived (p < 0.001). mSCOPE correlated to disease severity (p < 0.001) and to the number and severity of comorbidities (p < 0.001). Furthermore, mSCOPE significantly correlated with days on mechanical ventilation (p < 0.001) and days of ICU stay (p = 0.003). mSCOPE was found to be an independent predictor of mortality (HR:1.219, 95% CI: 1.010-1.471, p = 0.039), with a value ≥ 6 predicting poor outcome with a sensitivity (95%CI) 88.6%, specificity 29.7%, a positive predictive value of 31.5%, and a negative predictive value of 87.7%. CONCLUSION: mSCOPE score could be proved useful in patients' risk stratification, guiding clinical interventions in patients with severe COVID-19.

Cutaneous Vasculopathy in a COVID-19 Critically Ill Patient: A Histologic, Immunohistochemical, and Electron Microscopy Study.

We describe a critically ill, SARS-CoV-2 positive patient with respiratory failure and thrombotic/livedoid skin lesions, appearing during the course of the disease. The biopsy of the lesions revealed an occlusive, pauci-inflammatory vasculopathy of the cutaneous small vessels characterized by complement and fibrinogen deposition on vascular walls, pointing to a thrombotic vasculopathy. Transmission electron microscopy of the affected skin failed to reveal any viral inclusions. Clinical evaluation and laboratory findings ruled out systemic coagulopathies and disseminated intravascular coagulation, drug-induced skin reaction, and common viral rashes. Our hypothesis is that the, herein evidenced, microvascular occlusive injury might constitute a significant pathologic mechanism in COVID-19, being a common denominator between cutaneous and pulmonary manifestations.

Acute life-threatening cardiac tamponade in a mechanically ventilated patient with COVID-19 pneumonia.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has recently evolved as a pandemic disease. Although the respiratory system is predominantly affected, cardiovascular complications have been frequently identified, including acute myocarditis, myocardial infarction, acute heart failure, arrhythmias and venous thromboembolic events. Pericardial disease has been rarely reported. We present a case of acute life-threatening cardiac tamponade caused by a small pericardial effusion in a mechanically ventilated patient with severe COVID-19 associated pneumonia. The patient presented acute circulatory collapse with hemodynamic features of cardiogenic or obstructive shock. Bedside echocardiography permitted prompt diagnosis and life-saving pericardiocentesis. Further investigation revealed no other apparent cause of pericardial effusion except for SARS-CoV-2 infection. Cardiac tamponade may complicate COVID-19 and should be included in the differential diagnosis of acute hemodynamic deterioration in mechanically ventilated COVID-19 patients.
