ACEing SARS, Influenza and others

May 13 2020

Two studies were published recently weighting in on the association of ACE-2 inhibitors (Angiotensin Converting Enzyme Inhibitors), ARBs (Angiotensin Receptor Blockers) and viral infections.

A group of cardiologists from continental Europe looked into SARS-CoV-2 virus, its tropism to angiotensin-converting enzyme 2 receptors, and cardiovascular mortality.

The study compared 2,022 patients with heart failure and 1,698 in validation cohort.

The bottom line:

  • The study does not support previous reports suggesting that ACE inhibitors or ARBs increase the vulnerability for COVID-19 through increased plasma ACE2 concentrations;

A group of cardiologists from the United Kingdom looked Into association between angiotensin blockade and the incidence of influenza.

The bottom line:

  • The use of ACE inhibitors and ARBs was associated with either no effect on the incidence of influenza or a lower incidence, depending on the duration of use. These associations regarding observed susceptibility to influenza may reflect mechanisms that are shared with coronaviruses, including SARS-CoV-2.

Dr. Why bottom line:

  • SARS-CoV-2 and Influenza affect angiotensin system in a similar manner, e.g. “novel” SARS-Cov-2 is old news;

  • ACE inhibitors and ARBs are associated with lower incidence of influenza and are not associated with higher risk of cardiovascular events in COVID-19;

  • We shall consider small doses of ACE inhibitors and ARBs for chemoprophylaxis of these infections;

  • Under no circumstances STOP your medications.

Surprise, surprise! Dr. Why was right!
