ABSTRACT
Coronavirus disease 2019 (COVID-19) is due to severe acute respiratory syndrome coronavirus (SARS-CoV)-2 which binds and enters the host cells through the angiotensin-converting enzyme (ACE)2. While the potential for benefit with the use of renin-angiotensin-aldosterone system inhibitors (RAASi) and the risks from stopping them is more evident, potential harm by RAΑSi may also be caused by the increase in the activity of the ACE2 receptor, the inefficient counter regulatory axis in the lungs in which the proinflammatory prolyloligopeptidase (POP) is the main enzyme responsible for the conversion of deleterious angiotensin (ANG) II to protective ANG [1-7] and the proinflammatory properties of ACE2(+) cells infected with SARS-CoV-2. Acknowledging the proven RAΑSi benefit in patients with several diseases such as hypertension, heart failure, coronary disease, and diabetic kidney disease in the non-COVID-19 era, it is a reasonable strategy in this period of uncertainty to use these agents judiciously with careful consideration and to avoid the use of RAASi in select patients whenever possible, until definitive evidence becomes available.
