This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
BackgroundAn association among the use of angiotensin-converting-enzyme(ACE) inhibitors and angiotensin-receptor blockers(ARBs) with the clinical outcomes of coronavirus disease 2019 (COVID-19) is unclear. MethodsPubMed, EMBASE, and the preprint databases MedRxiv and BioRxiv were searched for relevant studies that assessed the association among inflammation level, application of ACEI/ARB, infection severity and death in patients with COVID-19. Odd risks(OR) and 95% confidence interval (CI) were combined using random-effects or fixed models depending on heterogeneity. ResultsEleven studies were included with a total of 33,483 patients. Our review showed ACEI/ARB therapy might be associated with the reduced inflammatory factor (interleukin-6) and elevated level of immune cells(CD3, CD8). Meta-analysis showed no significant increase in the risk of COVID-19 infection(OR0.95, 95%CI0.89-1.05) in patients receiving ACEI/ARB therapy, and ACEI/ARB therapy was associated with a decreased risk of severe COVID-19 (OR0.75, 95%CI 0.59-0.96) and mortality (OR0.52, 95%CI 0.35-0.79). Subgroup analyses showed that, among the general population, application of ACEI/ARB therapy was associated with reduced risks of all-cause death(OR0.31, 95%CI 0.13-0.75), and the risk of severe COVID-19(OR0.79, 95%CI 0.60-1.05) infection and COVID-19 infection(OR0.85, 95% CI 0.66-1.08) were not increased. Among patients with hypertension, the use of an ACEI/ARB was associated with a lower severity of COVID-19(OR0.73, 95%CI 0.51-1.03) and lower mortality(OR0.57, 95%CI 0.37-0.87), without evidence of an increased risk of COVID-19 infection(OR1.00, 95%CI 0.90-1.12). ConclusionOn the basis of the available evidence, this is the first meta-analysis showed that, in general population, the use of ACEI/ARB therapy was safe without an increased risk of COVID-19 infection and with a decreasing trend of severe COVID-19 infection and lower mortality. In patients with hypertension, the use of ACEI/ARB therapy should be encouraged, without increased risk of COVID-19 inflection, and better prognosis (a decreasing trends of severe COVID-19 and reduced all-cause death). Overall, ACEI/ARB therapy should be continued in patients who are at risk for, or have COVID-19, either in general population or hypertension patients. Our results need to be interpreted with caution considering the potential for residual confounders, and more well-designed studies that control the clinical confounders are necessary to confirm our findings.
