  • Interaction between RAAS inhibitors and ACE2 in the context of COVID-19

    Jean-Jacques Mourad & Bernard I. Levy

    Nature Reviews Cardiology (2020)

    In the Comment article by Zheng and colleagues (COVID-19 and the cardiovascular system. Nat. Rev. Cardiol. https://doi.org/10.1038/s41569-020-0360-5 (2020)), the crucial role of angiotensin-converting enzyme 2 (ACE2) in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, which causes coronavirus disease 2019 (COVID-19), was highlighted. ACE2 is a membrane-bound aminopeptidase that cleaves angiotensin I and angiotensin II into the angiotensin-(1–9) and angiotensin-(1–7) peptides. Several studies support the existence of a cardiovascular-protective ACE2–angiotensin-(1–7)–Mas receptor axis.

    • Renin–Angiotensin–Aldosterone System Inhibitors in Patients with Covid-19 List of authors. Muthiah Vaduganathan, M.D., M.P.H., Orly Vardeny, Pharm.D., Thomas Michel, M.D., Ph.D., John J.V. McMurray, M.D., Marc A. Pfeffer, M.D., Ph.D., and Scott D. Solomon, M.D. The renin–angiotensin–aldosterone system (RAAS) is an elegant cascade of vasoactive peptides that orchestrate key processes in human physiology. Severe acute respiratory syndrome coronavirus 1 (SARS-CoV-1) and SARS-CoV-2, which have been responsible for the SARS epidemic in 2002 to 2004 and for the more recent coronavirus disease 2019 (Covid-19) pandemic, respectively, interface with the RAAS through angiotensin-converting enzyme 2 (ACE2), an enzyme that physiologically counters RAAS activation but also functions as a receptor for both SARS viruses.1,2 The interaction between the SARS viruses and ACE2 has been proposed as a potential factor in their infectivity,3,4 and there are concerns about the use of RAAS inhibitors that may alter ACE2 and whether variation in ACE2 expression may be in part responsible for disease virulence in the ongoing Covid-19 pandemic.
