Since the effects of renin–angiotensin–aldosterone system (RAAS) inhibitors on the clinical outcomes of coronavirus disease-19 (COVID-19) have been conflicting in different studies, we performed this meta-analysis. A systematic search of published articles was performed in PubMed and EMBASE from January-May 5, 2020. Studies that reported the clinical outcomes of patients with COVID-19, stratified by the class of concomitant antihypertensive drug therapy, were included. The Mantel-Haenszel random effects model was used to estimate pooled odds ratio (OR). A total of 6,997 hypertensive patients with COVID-19 were included. The overall risk of poor patient outcomes (severe COVID-19 or death) was lower in patients taking RAAS inhibitors (OR=0.84, 95% CI: [0.73, 0.96]; P=0.017) compared with those receiving non-RAAS inhibitor antihypertensives. Patients taking angiotensin-I-converting enzyme inhibitors (ACEIs) were less likely to experience poor clinical outcomes (OR=0.73, 95% CI: [0.58-0.92]; P=0.01) compared with those receiving angiotensin-II receptor blockers (ARBs). Compared to all other antihypertensives, ACEIs decreases the risk poor COVID-19 outcomes (OR=0.77, 95% CI: [0.63-0.93]) while ARBs did not (OR=1.13, 95% CI: [0.95-1.35]). The risk of poor patient outcomes from COVID-19 was lower in patients who received RAAS inhibitors compared with those who took non-RAAS inhibitors. Unlike ARBs, ACEIs might help in decreasing the severity and mortality of COVID-19.

AbstractIntroductionThe effects of renin–angiotensin–aldosterone system (RAAS) inhibitors on the clinical outcomes of coronavirus disease-19 (COVID-19) have been conflicting in different studies. This meta-analysis was undertaken to provide more conclusive evidence.MethodsA systematic search for published articles was performed in PubMed and EMBASE from January 5 2020 till May 5 2020. Studies that reported the clinical outcomes of patients with COVID-19, stratified by the class of concomitant antihypertensive drug therapy, were included. The Mantel-Haenszel random effects model was used to estimate pooled odds ratio (OR).ResultsA total of 6,997 patients with COVID-19 were included, and all of them had hypertension. The overall risk of poor patient outcomes (severe COVID-19 or death) was lower in patients taking RAAS inhibitors (OR=0.84, 95% CI: [0.73, 0.96]; P=0.017) compared with those receiving non-RAAS inhibitor antihypertensives. Patients taking angiotensin-I-converting enzyme inhibitors (ACEIs) were less likely to experience poor clinical outcomes (OR=0.73, 95% CI: [0.58-0.92]; P=0.01) compared with those receiving angiotensin-II receptor blockers (ARBs). In addition, comparison of ACEIs to the rest of non-ACEI antihypertensives gave a consistently decreased risk of poor COVID-19 outcome (OR=0.77, 95% CI: [0.63-0.93]; P=0.002). However, ARBs did not decrease the risk of poor COVID-19 outcomes compared to all other non-ARB antihypertensives (OR=1.13, 95% CI: [0.95-1.35]).ConclusionThe risk of developing severe illness or death from COVID-19 was lower in patients who received RAAS inhibitors compared with those who took non-RAAS inhibitors. ACEIs might be better in decreasing the severity and mortality of COVID-19 than ARBs.

Abstract Background: Reports on the effects of renin–angiotensin–aldosterone system (RAAS) inhibitors on the clinical outcomes of coronavirus disease-19 (COVID-19) have been conflicting. We performed this meta-analysis to find conclusive evidence. Methods: We searched published articles through PubMed, EMBASE and medRxiv from 5 January 2020 to 3 August 2020. Studies that reported clinical outcomes of patients with COVID-19, stratified by the class of antihypertensives, were included. Random and fixed-effects models were used to estimate pooled odds ratio (OR). Results: A total 36 studies involving 30,795 patients with COVID-19 were included. The overall risk of poor patient outcomes (severe COVID-19 or death) was lower in patients taking RAAS inhibitors (OR=0.79, 95% CI: [0.67, 0.95]) compared with those receiving non-RAAS inhibitor antihypertensives. However, further sub-meta-analysis showed that specific RAAS inhibitors did not show a reduction of poor COVID-19 outcomes when compared with any class of antihypertensive except beta-blockers (BBs). For example, compared to calcium channel blockers (CCBs), neither angiotensin-I-converting enzyme inhibitors (ACEIs) (OR=0.91, 95% CI: [0.67, 1.23]) nor angiotensin-II receptor blockers (ARBs) (OR=0.90, 95% CI: [0.62, 1.33]) showed a reduction of poor COVID-19 outcomes. When compared with BBs, however, both ACEIs (OR=0.85, 95% CI: [0.73, 0.99) and ARBs (OR=0.72, 95% CI: [0.55, 0.94]) showed an apparent decrease in poor COVID-19 outcomes. Conclusions: RAAS inhibitors did not increase the risk of mortality or severity of COVID-19. Differences in COVID-19 clinical outcomes between different class of antihypertensive drugs were likely due to the underlying comorbidities for which the antihypertensive drugs were prescribed.

Background: It is unclear whether angiotensin-converting enzyme inhibitors (ACEIs) in combination with angiotensin II receptor blockers (ARBs) are superior to ACEIs or ARBs alone in the treatment of nondiabetic chronic kidney disease (CKD). The present meta-analysis was designed to assess the efficacy and safety of ACEIs in combination with ARBs in nondiabetic CKD. Methods: The PubMed, Embase, and Cochrane Library databases were searched to identify randomized controlled trials (RCTs) published prior to March 2020. A random-effects model was used to calculate the effect sizes of eligible studies. Results: The present meta-analysis of 20 RCTs encompassing 1,398 patients with nondiabetic CKD demonstrated that ACEIs in combination with ARBs were superior to ACEIs or ARBs alone in reducing urine albumin excretion (SMD, -0.69; 95% CI, -1.13 to -0.25; P=0.002), urine protein excretion (SMD, -0.34; 95% CI, -0.46 to -0.23; P<0.001) and blood pressure (systolic blood pressure: WMD, -1.43; 95% CI, -2.42 to -0.44; P=0.005; diastolic blood pressure: WMD, -1.85; 95% CI, -2.67 to -1.04; P<0.001) without decreased glomerular filtration rate (SMD, -0.07; 95% CI, -0.20 to 0.06; P=0.30) or increased incidences of hyperkalaemia (RR, 1.25; 95% CI, 0.47 to RR=0.80; P=0.20 to 0.06; P=0.30). Conclusion: Compared with ACEIs or ARBs alone, ACEIs in combination with ARBs are effective and safe in the treatment of nondiabetic CKD. ACEIs combined with ARBs may be a better choice to reduce proteinuria as long as it can be tolerated. (PROSPERO number: CRD42020179398).
