1 The Use of Angiotensin Converting Enzyme Inhibitors and Incident Respiratory Infections, Are They Harmful or Protective? An Analysis Using UK Based Electronic Health Records of 5.6 Million Individuals.

The study use UK based linked electronic health records from the Clinical Research Datalink (CALIBER) of 5.6 million individuals to conduct a matched case-control study to investigate the incidence of influenza in individuals prescribed ACEI compared to those not prescribed ACEI.

2 The CORONAvirus Disease 2019 Angiotensin Converting Enzyme Inhibitor/Angiotensin Receptor Blocker InvestigatiON (CORONACION) Randomized Clinical Trial

Coronavirus disease 2019 (COVID-19) is a pandemic infection caused by a virus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Because SARS-CoV-2 is known to require the angiotensin-converting enzyme 2 (ACE-2) receptor for uptake into the human body, there have been questions about whether medications that upregulate ACE-2 receptors might increase the risk of infection and subsequent complications. One such group of medications are anti-hypertensives that block the renin-angiotensin system, including both angiotensin converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARB). Both ACEi and ARB are widely used for the treatment of hypertension. Early reports from China and Italy suggest that many of those who die from COVID-19 have a coexisting history of hypertension. Consequently, there have been questions raised as to whether these 2 types of blood pressure medication might increase the risk of death among patients with COVID-19. However, it is well known that the prevalence of hypertension increases linearly with age. Therefore, it is possible that the high prevalence of hypertension and ACEi/ARB use among persons who die from COVID-19 is simply confounded by age (older people are at risk of both a history of hypertension and dying from COVID-19). Whether these commonly prescribed blood pressure medications increase the risk of COVID-19 or not remains unanswered. Statements from professional cardiology societies on both sides of the Atlantic have called for urgent research into this question. Our study aims to randomize patients with primary (essential) hypertension who are already taking ACEi/ARB to either switch to an alternative BP medication or continue with the ACEi/ARB that they have already been prescribed. Adults with compelling indications for ACEi/ARB will not be enrolled.

3 Evaluation of Influenza Vaccination and Treatment With ACEI and ARB in the Evolution of SARS-Covid19 Infection

Some authors have proposed the use of the flu vaccine to reduce the severity of COVID-19 cases, while some have proposed the use of ACE Inhibitors (ACEI) or Angiotensin Receptor blockers (ARB), since this virus shares hemagglutinin as a transmission mechanism and acts on the ACE2 enzyme during infection. The aim is to evaluate whether the admitted patients who are previously vaccinated or those who were already receiving treatment show a better evolution.
