Iper-infiammazione e squilibrio del sistema renina-angiotensina-aldosterone in corso di COVID-19: una nuova ipotesi per il sospetto clinico di ipercoagulabilità e immuno-trombosi microvascolare
Hyperinflammation and derangement of renin-angiotensin-aldosterone system in COVID-19: A novel hypothesis for clinically suspected hypercoagulopathy and microvascular immunothrombosis.
<p>Early clinical evidence suggests that severe cases of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), are frequently characterized by hyperinflammation, imbalance of renin-angiotensin-aldosterone system, and a particular form of vasculopathy, thrombotic microangiopathy, and intravascular coagulopathy. In this paper, we present an immunothrombosis model of COVID-19. We discuss the underlying pathogenesis and the interaction between multiple systems, resulting in propagation of immunothrombosis, which through investigation in the coming weeks, may lead to both an improved understanding of COVID-19 pathophysiology and identification of innovative and efficient therapeutic targets to reverse the otherwise unfavorable clinical outcome of many of these patients.</p>
<p>Background: due to the important abnormalities observed in the concentration of many inflammation/infection biomarkers in patients with coronavirus disease 2019 (COVID-19), this study was aimed to evaluate whether the assessment of C-Reactive Protein (CRP), interleukin 6 (IL-6) and procalcitonin (PCT) could help predicting SARS-CoV-2 positivity at emergency department (ED) presentation in patients with suspected infection.<br />Methods: the study population consisted of patients consecutively admitted to the ED of the University Hospital of Verona, with clinical suspicion of SARS-CoV-2 infection over a 2-week period. Blood samples as well as oropharyngeal and nasopharyngeal swabs were collected upon ED admission.<br />Results: the final study population consisted of 92 patients, 48 with negative and 44 with positive SARS-CoV-2 swabs. No significant differences were observed in concentrations of CRP, IL-6, or PCT between patients with or without acute SARS-CoV-2 infection. A significant correlation was found between CRP and IL-6 in both negative (r=0.77) and positive (r=0.74) SARS-CoV-2 cases, between CRP and PCT in SARS-CoV-2 negative (r=0.38) and positive (r=0.44) cases, and between IL-6 and PCT in SARS-CoV-2 negative (r=0.37) and positive (r=0.40) cases. The area under the curve (AUC) of none of the biomarkers could efficiently discriminate patients with negative or positive swabs (CRP: 0.52; IL-6: 0.51; PCT: 0.53).<br />Conclusions: routine measurement of CRP and IL-6, together with PCT, does not seem a useful pre-test strategy in ED patients with clinical suspicion of COVID-19.</p>
