Role of Drugs used for chronic disease management on Susceptibility and Severity of COVID-19: A Large Case-Control Study

Abstract

AbstractThe study aimed to investigate whether specific medications used in the treatment chronic diseases affected either the development and/ or severity of COVID-19 in a cohort of 610 COVID-19 cases and 48,667 population-based controls from Zheijang, China. Using a cohort of 578 COVID-19 cases and 48,667 population-based controls from Zheijang, China we tested the role of usage of cardiovascular, antidiabetic and other medications on risk and severity of COVID 19. Analyses were adjusted for age, sex and BMI and for presence of relevant comorbidities. Individuals with hypertension taking calcium channel blockers had significantly increased risk [odds ratio (OR)= 1.73 (95% CI 1.2-2.3)] of manifesting symptoms of COVID-19 whereas those taking angiotensin receptor blockers and diuretics had significantly lower disease risk (OR=0.22; 95%CI 0.15-0.30 and OR=0.30; 95%CI 0.19-0.58 respectively). Among those with type 2 diabetes, dipeptidyl peptidase-4 inhibitors (OR= 6.02; 95% CI 2.3-15.5) and insulin (OR= 2.71; 95% CI 1.6-5.5) were more and glucosidase inhibitors were less prevalent (OR= 0.11; 95% CI 0.1-0.3) among with COVID-19 patients.Drugs used in the treatment of hypertension and diabetes influence the risk of development of COVID-19, but, not its severity.Study highlightsWhat is the current knowledge on the topic?Cardiovascular disease and Diabetes have been highlighted as comorbidities contributing to a more severe form of COVID-19 and medication to treat them may also influence the risk of COVID-19 and its clinical outcomes.What question did this study address?Does specific medications used in the treatment of chronic diseases influence the risk for the susceptibility to SARS CoV-2 infection of severity of COVID-19?What does this study add to our knowledge?The study confirms that higher BMI, diabetes and cardio/ cerebrovascular disease as independent risk factors for the development of COVID-19. Angtiotensin Receptor Blockers (ARBs) and diuretics were associated with reduced risk and Calcium Channel Blockers (CCBs) with increased risk of developing COVID-19. Among those with type 2 diabetes, dipeptidyl peptidase-4 and were associated with increased and glucosidase inhibitors with reduced risk development of COVID-19. None of the antihypertensive or anti-diabetic drugs were associated with increased risk of severe or critical form of the infection.Drugs used in the treatment of hypertension and diabetes influence the risk of development of COVID-19, but are not associated with severity of the disease.How might this change clinical pharmacology or translational science?Findings from the current large case-control study confirmed no evidence to alter ARBs or ACEIs therapy in the context of COVID-19 severity in clinical practice. Hypertension significantly increases the risk of severe or critical SARS-CoV-2 infection indicating that carefully controlled blood pressure should be a priority to reduce the healthcare burden of COVID-19.
