AbstractTwenty years ago, an enzyme homologous to the previously known angiotensin-converting enzyme (ACE) was identified, and subsequently named ACE2. In the renin-angiotensin system (RAS), ACE2 has counter-regulatory functions against the classical effector peptide angiotensin II, for example in blood pressure regulation and cardiovascular remodeling. However, ACE2 provides an initially unexpected interesting link between virology and cardiovascular medicine. That is, ACE2 represents the binding receptor for the cellular uptake of SARS-CoV and SARS-CoV-2 viruses. Thus, ACE2 is relevant for COVID-19. In this context, it was suspected that therapy with RAS blockers might promote transmission and complications of COVID-19 by upregulation of ACE2 expression. The aim of this short review is, to describe the link between the RAS, particularly ACE2, and COVID-19. Based on our analysis and evaluation of the available findings, we justify our conclusion: important drugs such as ACE inhibitors and angiotensin receptor blockers should continue to be prescribed according to guidelines to stable patients in the context of the COVID-19 pandemic.

The renin-angiotensin system plays a very critical role in hypertension, diabetes, and kidney and heart diseases. The blockade of the renin-angiotensin system results in the prevention of progression of renal and cardiac damage. There have been controversial hypotheses raised regarding the safety of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in COVID-19 (coronavirus disease 2019). We present the case series of four patients (2 men and 2 women; 1 Caucasian and 3 African Americans; two survived and two died) with confirmed COVID-19, presenting with respiratory symptoms and acute kidney injury, who have been on angiotensin-converting enzyme inhibitors or angiotensin receptor blockers. Membrane-bound angiotensin-converting enzyme 2 (ACE2) has been implicated as the gateway for viral entry into the human cell in causing the infection. The factors contributing to acute kidney injury are diuretics, iodinated contrast administration, hemodynamic instability apart from ACE inhibitors, and angiotensin receptor blockers. The ACE inhibitors and ARBs were stopped in these patients due to acute kidney injury. We also discussed the role of ACE2 and the renin-angiotensin system (RAS) blockade in patients with COVID-19 infection along with pathogenesis.
