Plasma Renin Concentration in Critically Ill COVID-19 Patients

Zusammenfassung:Investigations of plasma renin concentration as a marker of organ perfusion in several intensive care settings have shown a significant correlation between its increase and a lack of perfusion in critical tissues, especially in septic patients. Castillo et al. proposed that activation of the non-canonical pathway of the renin–angiotensin–aldosterone system could improve cardiovascular homeostasis under COVID-19. During the first wave of COVID-19, we preliminarily enrolled a small cohort of subjects admitted to the Intensive Care Unit with a diagnosis of COVID-19 and acute respiratory distress syndrome. Their plasma renin value was measured in the first 24 h (T0), in the following 72 h (T1), and after one week (T2). In eight patients, we observed a higher plasma renin concentration—patients with difficulty weaning and in non-survivors. This is a preliminary observation. The variation of plasma renin levels in a septic condition is known, but settings such as COVID-19 infection have recently been investigated, showing a correlation with angiotensin-converting enzyme 2 receptor expression and functionality; in the near future, it will be interesting to have more data about its variation and value in COVID-19 patients.
