Abstract

There has been much speculation in journals as well as social and traditional media about a link between popularly used classes of drugs that inhibit the renin-angiotensin system (RAS) and novel coronavirus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) infection or coronavirus disease 2019 (COVID-19) disease severity. After examining the available evidence, we advise that inhibitors of the RAS pathway should be continued in patients with COVID-19 who are taking these drugs for evidence-based indications. The putative link between SARS-CoV-2 angiotensin-converting enzyme inhibitors (ACEis) and angiotensin receptor blockers (ARBs) can be rationalized by the biology of virus entry. The spike protein of SARS-CoV-2 uses angiotensin-converting enzyme 2 (ACE2) as a receptor to enter type II pneumocytes or enterocytes (and likely, other cells).

To the Editor,

On January 29, 2020, two Chinese spouses (patient 1, female; patient 2, male), coming to Italy as tourists from Hubei province, were hospitalized at the National Institute for Infectious Diseases “L. Spallanzani”, Rome, with fever and respiratory symptoms. SARSCoV-2 diagnosis was accomplished using real-time RT-PCR on a nasopharyngeal swab and sputum for patient 1 and on a nasopharyngeal swab for patient 2, collected 1 day after symptom onset. Partial sequencing confirmed both patients to be infected with SARS-CoV-2
