Bidirectional Relationship between COVID-19 and Diabetes: Role of Renin-Angiotensin-Aldosterone System and Drugs Modulating It

Numerous reports have suggested that diabetic patients are at high risk for the development of severe symptoms of coronavirus disease-2019 (COVID-19). However, a few studies have recently proposed that the relationship between diabetes and COVID-19 is bidirectional, as severe acute respiratory syndrome-coronavirus-2 also has the capability to induce diabetes. Various mechanisms have been identified and proposed to be involved in this binary association. In this review, the importance and impact of renin-angiotensin-aldosterone system (RAAS) in this two-way association of COVID-19 and diabetes has been summarized. The role and effect of drugs modulating RAAS directly or indirectly has also been discussed, as they can majorly impact the course of treatment in such patients. Further reports and data can present a clear picture of RAAS and its modulators in restoring the balance of dysregulated RAAS in COVID-19.

Automated summary

Diabetic patients are at high risk for severe symptoms of COVID-19, with some studies suggesting that COVID-19 can also induce diabetes. The renin-angiotensin-aldosterone system (RAAS) plays an important role in the bidirectional association between COVID-19 and diabetes.
