About this study

Official title: Association Between Hypertension, Renin-Angiotensin-Aldosterone System Inhibitors and COVID-19

Background. Angiotensing converting enzyme type 2 (ACE2), a key enzyme of the renin-angiotensin-aldosterone system (RAAS), is the receptor of SARS-CoV-2 for cell entry into lungs. Because ACE2 may be modulated by RAAS inhibitors, such as angiotensin converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARBs), there is concern that patients treated with ACEi and ARBs may be at higher risk for COVID-19 infection and severity.

Aim. To analyze the associations between COVID-19 and hypertension, and treatments with ACEi and ARBs.

Methods. In this retrospective observational study, consecutive patients hospitalized for suspected COVID-19 pneumonia will be divided into 2 groups, whether or not COVID-19 is confirmed. The two groups will be compared for baseline characteristics, mainly prior treatment with ACEi and ARBs, and clinical outcome at 1-month follow-up.

The main hypothesis is that ACEi and ARBs, which interact differently with ACE2, may have different relationships with COVID-19 infection or severity.

Read the detailed description

The coronavirus disease 2019 (Covid-19) pandemic is currently the main challenge facing healthcare providers. Data are lacking to guide clinical decision.

The renin-angiotensin-aldosterone system (RAAS) is a key process in cardiology. Its inhibition using angiotensin-converting enzyme inhibitors (ACEi) and angiotensin II type 1-receptor blockers (ARBs) is a cornerstone of the long-term management of arterial hypertension, heart failure and acute coronary syndrome. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) uses the angiotensin-converting enzyme 2 (ACE2) as a cellular entry receptor. ACE2 is part of the RAAS and is likely to be modulated by the use of ACEi and ARBs. Therefore, there is concern that patients who are treated with ACEi and ARBs may be at higher risk for Covid-19 infection.

However, little is known regarding how ACEi and ARBs could affect Covid-19 infection and severity. First, ACE2 may have a protective effect against lung injury because it degrades angiotensin II to angiotensin-(1-7). Second, the effect of RAAS inhibition on ACE2 expression has been poorly studied in humans. Third, ACE inhibitors and ARB have different effect on the RAAS and therefore their interaction with Covid-19 may differ.

The COVHYP study is designed to address part of these issues. This is an analytical retrospective observational study that will collect and analyze data regarding patients hospitalized with suspected Covid-19. We planned to screen for inclusion all consecutive patients referred form 10/03/2020 to 15/04/2020 to the emergency department of the Versailles Hospital, a tertiary center located in greater Paris area - one of the region most affected by Covid-19 in France through this period. The inclusion criteria are as follows: 1) Clinical presentation suggestive of COVID-19 pneumonia, at least fever or influenza-like syndrome AND cough or dyspnea; and 2) Test of the presence of SARS-CoV-2 RNA by RT-PCR in nasopharyngeal or sputum samples. Two groups of patients will be defined, those with confirmed Covid-19 pneumonia, and those without Covid-19. Hospital data will gathered, and patients or relatives will be contacted by phone for a one-month follow-up. We will compare baseline characteristics of patients, especially the previous treatment by ACEi or ARBs, in the two groups of patients, and evaluate whether these characteristics can be associated with diagnosis of SARS-CoV-2 infection and severity.

We hope that this study will provide a better understanding of the effect of RAAS inhibitors on Covid-19 pneumonia and its severity.

Study groups in NCT04374695
Study groupRoleWhat they receive
patients with COVID-19Patients with positive RT-PCR for SARS-CoV-2, and patients with négative RT-PCR for SARS-CoV-2 but clinical presentation highly suggestive of COVID-19, and typical COVID-19 abnormalities on chest CT-Scan.
patients without COVID-19Patients with négative RT-PCR for SARS-CoV-2 and chest CT-Scan or chest X-ray not suggestive of COVID-19

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Prior treatment by ACEi

    Prevalence of a previous treatment by angiotensin converting enzyme inhibitors in patients with and without confirmed Covid-19 pneumonia.

    Measured: at admission to hospital

  2. Prior treatment by ARB

    Prevalence of a previous treatment by angiotensin II type 1-receptor blockers in patients with and without confirmed Covid-19 pneumonia.

    Measured: at admission to hospital

Secondary outcomes (2)
  1. Baseline characteristics and comorbidities

    Association between COVID-19 infection status and other baseline characteristics and comorbidities (age, sex, history of hypertension, chronic heart disease, diabetes mellitus, COPD, asthma, obesity, allergies)

    Measured: at admission to hospital

  2. Major Clinical Adverse Events

    Association between previous treatment by ACEi and ARBs and clinical course of COVID-19 (one-month mortality, hospitalization in intensive care unit, duration of hospital stay, early discharge to home)

    Measured: One month follow-up

Questions about this trial

What is this clinical trial studying?

An observational study of COVID-19, run by Versailles Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 5 May 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Jean-Louis GEORGES, MD, MPH (33+139638870, jgeorges@ch-versailles.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Prior treatment by ACEi (time frame: at admission to hospital). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 May 2020.
