Elimination or Prolongation of ACE Inhibitors and ARB in Coronavirus Disease 2019

Completed · Not applicable

Conditions studied: COVID-19

In brief

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for coronavirus disease 2019 (COVID-19), is associated with a high incidence of acute respiratory distress syndrome (ARDS) and death. Hypertension and cardiovascular disease are risk factors for death in COVID-19. Angiotensin converting enzyme 2 (ACE2), an important component of the renin-angiotensin system, serves as the binding site of SARS-CoV-2 and facilitates host cell entry in the lungs. In experimental models, angiotensin converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) have been shown to increase ACE2 expression in several organs, potentially promoting viral cell invasion, although these findings are not consistent across studies. Alternatively, ACEIs and ARBs may actually improve mechanisms of host defense or hyperinflammation, ultimately reducing organ injury. Finally, ACEIs and ARBs may have direct renal, pulmonary and cardiac protective benefits in the setting of COVID-19. Therefore, it is unclear if ACEIs and ARBs may be beneficial or harmful in patients with COVID-19. Given the high prevalence of hypertension, cardiovascular and renal disease in the world, the high prevalence of ACEIs or ARBs in these conditions, and the clinical equipoise regarding the continuation vs. discontinuation of ACEIs/ARBs in the setting of COVID, a randomized trial is urgently needed. The aim of this trial is to assess the clinical impact of continuation vs. discontinuation of ACE inhibitors and angiotensin receptor blockers on outcomes in patients hospitalized with COVID-19.
