To investigate the effects of renin-angiotensin-aldosterone system (RAAS) inhibitors on the prognosis in patients with coronavirus disease 2019 (COVID-19). A meta-analysis was performed. We systematically searched PubMed, the Cochrane Library, the Web of Science, EMBASE, medRxiv, and bioRxiv database through October 30, 2020. The primary and secondary outcomes were mortality and severe COVID-19, respectively. We included 25 studies with 22,734 COVID-19 patients, and we compared the outcomes between patients who did and did not receive angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEIs/ARBs). The use of ACEIs/ARBs was not associated with higher risks of severe disease (odds ratio [OR] = 0.89; 95% confidence interval [CI]: 0.63, 1.15; I2 = 38.55%), mechanical ventilation (OR = 0.89; 95% CI: 0.61, 1.16; I2 = 3.19%), dialysis (OR = 1.24; 95% CI: 0.09, 2.39; I2 = 0.00%), or the length of hospital stay (SMD = 0.05; 95% CI: -0.16, 0.26; I2 = 84.43%) in COVID-19 patients. The effect estimates showed an overall protective effect of ACEIs/ARBs against mortality (OR = 0.65; 95% CI: 0.46, 0.85; I2 = 73.37%), severity/mortality (OR = 0.69; 95% CI: 0.43, 0.95; I2 = 22.90%), transfer to the intensive care unit among COVID-19 patients with hypertension (OR = 0.36, 95% CI: 0.19, 0.53, I2 = 0.00%), hospitalization (OR = 0.79; 95% CI: 0.60, 0.98; I2 = 0.00%), and acute respiratory distress syndrome (OR = 0.71; 95% CI: 0.46, 0.95; I2 = 0.00%). The use of RAAS inhibitor was not associated with increased mortality or disease severity in COVID-19 patients. This study supports the current guidelines that discourage the discontinuation of RAAS inhibitors in COVID-19 patients.

COVID-19 is a big concern in the world. The coronavirus is known as connecting with ACE2 receptor, thus discontinuation of ARB was thought to be necessary in patients with hypertension treated with this medicine. This meta-analysis shows there was no obvious relation with discontinuation of ARB. According to these data, we should keep giving ARB to these patients.
These results confirm what I and most of my colleagues know about the effect of renin-angiotensin-aldosterone system (RAAS) inhibitors on the prognosis in patients with COVID-19.
This study confirms existing knowledge on this topic.
This meta analysis of 25 studies showed that the use of ACEIs/ARBs does not worsen outcomes in COVID-19 and may even be protective.
