ACEI or ARB and COVID-19 Severity and Mortality in US Veterans

Summary

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for COVID-19, enters type II pneumocytes using angiotensin-converting enzyme 2 (ACE2). It is unclear whether ACE inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) increase, decrease, or have no significant effect on ACE2 expression or activity. Therefore, ACEI and ARB may be harmful, beneficial, or have no impact on Coronavirus Disease 2019 severity and mortality. The Specific Aims of this observational study are: (1) Among SARS-CoV-2-positive outpatients, compare all-cause hospitalization and mortality rates between: 1.1 Current users of a range of doses of ACEI/ARB- vs. non- ACEI/ARB-based regimens, and 1.2 Current users of a range of doses of ACEI- vs. ARB-based regimens, and (2) Among those hospitalized for COVID-19, compare all-cause mortality between: 2.1 Current users of a range of doses of ACEI/ARB- vs. non- ACEI/ARB-based regimens, and 2.2 Current users of a range of doses of ACEI- vs. ARB-based regimens.

Interventions

DRUG

ACEI/ARB

Veterans will be categorized as exposed to ACEI/ARB if they have one or more pharmacy fills for an oral ACEI or an ARB in the 90 days (± 14 days) prior to each Veteran's index date. Sacubitril/valsartan (Brand name: Entresto®) will be excluded from ARB exposures.

DRUG

Non-ACEI/ARB

Veterans will be categorized as exposed to a non-ACEI/ARB if they have one or more pharmacy fills for an oral non-ACEI or ARB medication in the 90 days (± 14 days) prior to each Veteran's index date and NO fills for an ACEI/ARB medication in the 90 days (± 14 days) prior to each Veteran's index date. Specific drug classes include: aldosterone receptor antagonist, beta-blocker, calcium channel blocker, centrally-acting drug, direct arterial vasodilator, direct renin inhibitor, thiazide diuretic, loop diuretic, and potassium sparing diuretic.

DRUG

ACEI

Veterans will be categorized as exposed to an ACEI if they have one or more pharmacy fills for an oral ACEI in the 90 days (± 14 days) prior to each Veteran's index date and NO fills for an oral ARB in the 90 days (± 14 days) prior to each Veteran's index date.

DRUG

ARB

Veterans will be categorized as exposed to an ARB if they have one or more pharmacy fills for an oral ACEI in the 90 days (± 14 days) prior to each Veteran's index date and NO fills for an oral ACEI in the 90 days (± 14 days) prior to each Veteran's index date. Sacubitril/valsartan (Brand name: Entresto®) will be excluded from ARB exposures.
