Study description

The coronavirus SARS-CoV-2 uses the protein ACE2 (angiotensin converting enzyme 2) as the receptor binding domain for its protein S (spike) to gain entry into cells and replicate. Blockers of the renin-angiotensin system (RAS) have been reported to upregulate the expression of ACE2 and this observation has raised the hypothesis that the use of these drugs could facilitate COVID-19 infection and/or make it more serious. Yet, the epidemiological evidence is lacking. The aim of this project is to carry out a quick case-population study using patients admitted to hospital with a diagnosis of COVID-19 as cases and a random sample of patients from a primary care database as the control series matched with cases for exact age, sex, and month-day (10 controls per case). Information on comorbidities and drugs used in the last month (current use) will be extracted from the clinical records in both cases and controls. We will examine the association of COVID-19 with the current use of RAS blockers as compared to non-use and as compared to current use of other antihypertensive drugs by computing the adjusted Odds Ratio through a conditional logistic regression model. The feasibility of selecting a secondary series of COVID-19+ cases who were not admitted to hospital (milder cases) will be assessed.
