The dramatic worldwide CoVID-19 infection requires the identification of a reliable and inexpensive tool to quickly discriminate patients with a more unfavorable outcome. Methods: We performed routine laboratory tests suitable to identify tissue damage and inflammatory status in 123 consecutive CoVID-19 patients admitted to the Emergency Department of the hospital of Piacenza (Emilia-Romagna, Northern Italy). The results were correlated with patients' respiratory function evaluated by the partial pressure of arterial oxygen to fraction of inspired oxygen ratio (PaO2/FiO2). Results: The most common laboratory abnormalities were lymphocytopenia and elevated values of C-reactive protein (CRP) and lactate dehydrogenase (LDH). Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and creatine kinase (CK) were also increased. The respiratory performance (PaO2/FiO2) showed a strong inverse correlation with LDH (r = 0.62, r 2 0.38, p value < 0.0001) and CRP (r = 0.55, r 2 0.31, p value < 0.0001). PaO2/FiO2 values also showed a significant inverse correlation with age (r = −0.37, p < 0.0001), AST (r = −0.31, p < 0.01), WBC (r = −0.49, p < 0.0001), neutrophils count (r = −0.5, p < 0.001). ROC curves showed a sensitivity of 75% and specificity of 70% for the LDH cutoff value of 450 U/L and a sensitivity of 72% and specificity of 71% for the CRP cutoff value of 11 mg/dl in identifying CoVID-19 with moderatesevere ARDS. Conclusions: LDH and CRP may be related to respiratory function (PaO2/FiO2) and be a predictor of respiratory failure in CoVID-19 patients. LDH and CRP should be considered a useful test for the early identification of patients who require closer respiratory monitoring and more aggressive supportive therapies to avoid poor prognosis.
Coronavirus disease 19 (COVID-19) is a worldwide infection which was recently declared a global health emergency by the WHO Emergency Committee. The most common symptoms are fever and cough, which can progress to pneumonia, acute respiratory distress syndrome (ARDS) and/or end-organ failure. Risk factors associated with ARDS and death are older age, comorbidities (e.g., hypertension, diabetes, hyperlipidaemia), neutrophilia, and organ and coagulation dysfunction. Disseminated intravascular coagulation and coagulopathy can contribute to death. Anticoagulant treatment is associated with decreased mortality in severe COVID-19 pneumonia. In this report we describe two patients with COVID-19 pneumonia who developed venous thromboembolism.
LEARNING POINTS• Deep vein thrombosis and pulmonary embolism can occur in patients with COVID-19 pneumonia.• Low-molecular-weight heparin prophylaxis does not decrease the risk of venous thromboembolism (VTE) in COVID-19 pneumonia. • In the presence of clinical signs and/or suspicion of VTE, compression ultrasound and echocardiography should be always performed, irrespective of disease stage.
We report the experience of prone ventilation in selected patients treated with helmet non-invasive ventilation (NIV) continuous positive airway pressure (CPAP) for acute respiratory failure in COVID-19 pneumonia. Preliminary results showed an improvement in the PaO2 value and PaO2/FiO2 ratio after 1 hour of prone ventilation. No variation of the lung ultrasound pattern before and after prone ventilation has been detected. At the time of writing, we attempted proning with helmet NIV CPAP in 10 patients. In 4 out of 10 patients, the attempt failed due to lack of compliance of the patient, scarce pain control even with ongoing treatment and refusal by the patient to prone positioning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
