Risks and Impact of Angiotensin-Converting Enzyme Inhibitors or Angiotensin-Receptor Blockers on SARS-CoV-2 Infection in Adults

BACKGROUND: The role of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin-receptor blockers (ARBs) in COVID-19 disease susceptibility, severity, and treatment is unclear. PURPOSE: To evaluate, on an ongoing basis, whether use of ACEIs or ARBs either increases risk for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or is associated with worse COVID-19 disease outcomes, and to assess the efficacy of these medications for COVID-19 treatment. DATA SOURCES: MEDLINE (Ovid) and Cochrane Database of Systematic Reviews from 2003 to 4 May 2020, with planned ongoing surveillance for 1 year; the World Health Organization database of COVID-19 publications and medRxiv.org through 17 April 2020; and ClinicalTrials.gov to 24 April 2020, with planned ongoing surveillance. STUDY SELECTION: Observational studies and trials in adults that examined associations and effects of ACEIs or ARBs on risk for SARS-CoV-2 infection and COVID-19 disease severity and mortality. DATA EXTRACTION: Single-reviewer abstraction confirmed by another reviewer, independent evaluation by 2 reviewers of study quality, and collective assessment of certainty of evidence. DATA SYNTHESIS: Two retrospective cohort studies found that ACEI and ARB use was not associated with a higher likelihood of receiving a positive SARS-CoV-2 test result, and 1 case-control study found no association with COVID-19 illness in a large community (moderate-certainty evidence). Fourteen observational studies, involving a total of 23 565 adults with COVID-19, showed consistent evidence that neither medication was associated with more severe COVID-19 illness (high-certainty evidence). Four registered randomized trials plan to evaluate ACEIs and ARBs for treatment of COVID-19. LIMITATION: Half the studies were small and did not adjust for important confounding variables. CONCLUSION: High-certainty evidence suggests that ACEI or ARB use is not associated with more severe COVID-19 disease, and moderate-certainty evidence suggests no association between use of these medications and positive SARS-CoV-2 test results among symptomatic patients. Whether these medications increase the risk for mild or asymptomatic disease or are beneficial in COVID-19 treatment remains uncertain. PRIMARY FUNDING SOURCE: None.

COVID-19 Evidence Reviews website: a VA effort to catalog and curate COVID-19 evidence reviews.

BACKGROUND: The COVID-19 pandemic has sparked a wave of SARS-CoV-2 and COVID-19 research that organizations around the world have been synthesizing in evidence reviews to provide high-quality evidence to support policymakers and clinicians. The urgency of these efforts opens these organizations to the risk of duplicated efforts, which could waste valuable time and resources. CASE PRESENTATION: The VA Evidence Synthesis Program (VA ESP) formed a COVID Response Team that launched an online catalog of COVID-19 evidence reviews in March 2020 (https://www.covid19reviews.org/). The goal of this website is to capture the work of evidence synthesis groups in the US and around the world to maximize their collective contributions to patients, frontline clinicians, researchers, and policymakers during the COVID-19 pandemic and avoid duplicating efforts. CONCLUSIONS: This ongoing and evolving project provides a helpful catalog of evidence reviews at various stages of production; in addition, the website provides further value with informational icons, review collections, and links to similar resources. The VA ESP will maintain this website to continue to support the needs of policymakers, clinicians, and researchers both within the VA and around the world throughout the COVID-19 pandemic.

Mental health outcomes of adults hospitalized for COVID-19: A systematic review.

BACKGROUND: Patients hospitalized for COVID-19 may be at high risk of mental health (MH) disorders. This systematic review assesses MH outcomes among adults during and after hospitalization for COVID-19 and ascertains MH care utilization and resource needs. METHODS: We searched multiple medical literature databases for studies published December 2019 to March 2021. Studies of ≥ 200 participants were synthesized. One reviewer completed article selection, data abstraction and assessed study quality and strength of evidence, with verification by a second. RESULTS: Fifty articles met preliminary inclusion criteria; 19 articles that included ≥ 200 participants were synthesized. Evidence from these primarily fair-quality studies suggests many patients experience symptoms of depression (9-66%), anxiety (30-39%), and insomnia (24-40%) during and 3 months after hospitalization for COVID-19. However, patients infrequently receive a new MH disorder diagnosis 6 months after hospitalization (5% are diagnosed with a new mood disorder, 7% anxiety disorder, and 3% insomnia). Some hospitalized patients - including women and those with more severe COVID-19 - may be at higher risk of poor MH outcomes. Data on MH care utilization and resource needs are currently limited. LIMITATIONS: Most included studies were small, did not report the proportion of participants with preexisting MH disorders, and did not use comparison groups. CONCLUSIONS: While many patients experience MH symptoms after hospitalization for COVID-19, most do not go on to develop a new MH disorder. Future studies should report whether participants have preexisting MH disorders and compare patients hospitalized for COVID-19 to patients hospitalized for other causes.

Major Update 2: Remdesivir for Adults With COVID-19: A Living Systematic Review and Meta-analysis for the American College of Physicians Practice Points.

BACKGROUND: Remdesivir is approved for the treatment of adults hospitalized with COVID-19. PURPOSE: To update a living review of remdesivir for adults with COVID-19. DATA SOURCES: Several electronic U.S. Food and Drug Administration, company, and journal websites from 1 January 2020 through 19 October 2021. STUDY SELECTION: English-language, randomized controlled trials (RCTs) of remdesivir for COVID-19. DATA EXTRACTION: One reviewer abstracted, and a second reviewer verified data. The Cochrane Risk of Bias Tool and GRADE (Grading of Recommendations Assessment, Development and Evaluation) method were used. DATA SYNTHESIS: Since the last update (search date 9 August 2021), 1 new RCT and 1 new subtrial comparing a 10-day course of remdesivir with control (placebo or standard care) were identified. This review summarizes and updates the evidence on the cumulative 5 RCTs and 2 subtrials for this comparison. Our updated results confirm a 10-day course of remdesivir, compared with control, probably results in little to no mortality reduction (5 RCTs). Updated results also confirm that remdesivir probably results in a moderate increase in the proportion of patients recovered by day 29 (4 RCTs) and may reduce time to clinical improvement (2 RCTs) and hospital length of stay (4 RCTs). New RCTs, by increasing the strength of evidence, lead to an updated conclusion that remdesivir probably results in a small reduction in the proportion of patients receiving ventilation or extracorporeal membrane oxygenation at specific follow-up times (4 RCTs). New RCTs also alter the conclusions for harms-remdesivir, compared with control, may lead to a small reduction in serious adverse events but may lead to a small increase in any adverse event. LIMITATION: The RCTs differed in definitions of COVID-19 severity and outcomes reported. CONCLUSION: In hospitalized adults with COVID-19, the findings confirm that remdesivir probably results in little to no difference in mortality and increases the proportion of patients recovered. Remdesivir may reduce time to clinical improvement and may lead to small reductions in serious adverse events but may result in a small increase in any adverse event.

Major Update: Remdesivir for Adults With COVID-19 : A Living Systematic Review and Meta-analysis for the American College of Physicians Practice Points.

BACKGROUND: Remdesivir is being studied and used for treatment of coronavirus disease 2019 (COVID-19). PURPOSE: To update a previous review of remdesivir for adults with COVID-19, including new meta-analyses of patients with COVID-19 of any severity compared with control. DATA SOURCES: Several sources from 1 January 2020 through 7 December 2020. STUDY SELECTION: English-language, randomized controlled trials (RCTs) of remdesivir for COVID-19. New evidence is incorporated by using living review methods. DATA EXTRACTION: 1 reviewer abstracted data; a second reviewer verified the data. The Cochrane Risk of Bias Tool and GRADE (Grading of Recommendations Assessment, Development and Evaluation) method were used. DATA SYNTHESIS: The update includes 5 RCTs, incorporating data from a new large RCT and the final results of a previous RCT. Compared with control, a 10-day course of remdesivir probably results in little to no reduction in mortality (risk ratio [RR], 0.93 [95% CI, 0.82 to 1.06]; 4 RCTs) but may result in a small reduction in the proportion of patients receiving mechanical ventilation (RR, 0.71 [CI, 0.56 to 0.90]; 3 RCTs). Remdesivir probably results in a moderate increase in the percentage of patients who recovered and a moderate decrease in serious adverse events and may result in a large reduction in time to recovery. Effect on hospital length of stay or percentage remaining hospitalized is mixed. Compared with a 10-day course for those not requiring ventilation at baseline, a 5-day course may reduce mortality, the need for ventilation, and serious adverse events while increasing the percentage of patients who recovered or clinically improved. LIMITATION: Summarizing findings was challenging because of varying disease severity definitions and outcomes. CONCLUSION: In hospitalized adults with COVID-19, remdesivir probably results in little to no mortality difference but probably improves the percentage recovered and reduces serious harms and may result in a small reduction in the proportion receiving ventilation. For patients not receiving ventilation, a 5-day course may provide greater benefits and fewer harms with lower drug costs than a 10-day course.
