COVID‐19 and renin angiotensin aldosterone system: Pathogenesis and therapy

ABSTRACT: Abstract

Aims

The severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) binds to the ACE2 component of the renin‐angiotensin aldosterone system (RAAS) and infects the human cells. The aims of the present review were to look at the role and alteration of the RAAS components in SARS‐CoV‐2 infection, therapeutic approaches, and clinical trials in this field.

Methods

We surveyed the literature (PubMed, Web of Science, and Scopus) till August 18, 2021, and 59 published papers regarding the components of the RAAS and their role and alterations in SARS‐CoV‐2 infection along with various COVID‐19 therapies based on the RASS components were included in the study.

Results

ACE inhibitors, angiotensin receptor blockers, and mineralocorticoid receptor inhibitors are agents that significantly enhance the ACE2 and Ang‐(1‐7) levels, which can be suggestive for their role as therapeutics against SARS‐CoV‐2 infection. Beta‐adrenergic blockers, which negatively regulate renin release from juxtaglomerular cells, and vitamin D, as a regulator of the RAAS and renin expression, are proposed therapeutics in the treatment of COVID‐19. Some antihyperglycemic agents could be potentially protective against COVID‐19‐induced lung injury. Also, the inhibition of the Janus kinase/signal transducer and activator of the transcription pathway as a potential treatment for COVID‐19 has been suggested. Finally, resveratrol, an antioxidant that can suppress Ang II, has been suggested as an adjunct to other therapies.

Conclusion

Regarding the suggested potential therapies for COVID‐19, there are many clinical trials whose results might change the treatment strategies of SARS‐CoV‐2 infection. So, the results of well‐organized clinical trials on the efficacy and safety of the mentioned agents in the treatment of COVID‐19 will be useful in the management and therapy of the disease.

Project description:BackgroundA potential association between the use of angiotensin-receptor blockers (ARBs) and angiotensin-converting-enzyme (ACE) inhibitors and the risk of coronavirus disease 2019 (Covid-19) has not been well studied.MethodsWe carried out a population-based case-control study in the Lombardy region of Italy. A total of 6272 case patients in whom infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was confirmed between February 21 and March 11, 2020, were matched to 30,759 beneficiaries of the Regional Health Service (controls) according to sex, age, and municipality of residence. Information about the use of selected drugs and patients' clinical profiles was obtained from regional databases of health care use. Odds ratios and 95% confidence intervals for associations between drugs and infection, with adjustment for confounders, were estimated by means of logistic regression.ResultsAmong both case patients and controls, the mean (±SD) age was 68±13 years, and 37% were women. The use of ACE inhibitors and ARBs was more common among case patients than among controls, as was the use of other antihypertensive and non-antihypertensive drugs, and case patients had a worse clinical profile. Use of ARBs or ACE inhibitors did not show any association with Covid-19 among case patients overall (adjusted odds ratio, 0.95 [95% confidence interval {CI}, 0.86 to 1.05] for ARBs and 0.96 [95% CI, 0.87 to 1.07] for ACE inhibitors) or among patients who had a severe or fatal course of the disease (adjusted odds ratio, 0.83 [95% CI, 0.63 to 1.10] for ARBs and 0.91 [95% CI, 0.69 to 1.21] for ACE inhibitors), and no association between these variables was found according to sex.ConclusionsIn this large, population-based study, the use of ACE inhibitors and ARBs was more frequent among patients with Covid-19 than among controls because of their higher prevalence of cardiovascular disease. However, there was no evidence that ACE inhibitors or ARBs affected the risk of COVID-19.
