Key result
The ACE D allele was not associated with overall COVID-19 risk but was clearly related to an enhanced risk of COVID-19 severity.
Why the study?
Research indicated a correlation between angiotensin-converting enzyme deletion and insertion polymorphism and COVID-19 risk, but conclusive evidence was lacking.
Does the ACE insertion/deletion polymorphism affect the risk and severity of COVID-19?
Meta-Analysis (n=5,674)
Does the ACE insertion/deletion polymorphism affect the risk and severity of COVID-19?
The ACE D allele is associated with an increased risk of severe COVID-19, suggesting genetic factors may influence disease progression.
Introduction. Research shows the correlation between angiotensin-converting enzyme (ACE) deletion and insertion (D/I) polymorphism and COVID-19 risk; yet, conclusive evidence is still lacking. Thus, a meta-analysis of relevant articles was performed to more accurately estimate the relationship of ACE I/D polymorphism with the risk of COVID-19. Material and Methods. Relevant literature from the PubMed database was systematically reviewed, and odds ratios (ORs) and associated 95% confidence intervals (CIs) were measured. Additionally, the metapackage from Stata version 15.0 was used for statistical analysis. Results. The meta-analysis eventually contained 8 studies, including 1362 COVID-19 cases and 4312 controls. Based on the data, the ACE I/D polymorphism did not show an association with COVID-19 risk (D vs. I: [Formula: see text], 95% [Formula: see text]; DD vs. II: [Formula: see text], 95% [Formula: see text]; DI vs. II: [Formula: see text], 95% [Formula: see text]; dominant model: [Formula: see text], 95% [Formula: see text]; and recessive model: [Formula: see text], 95% [Formula: see text]). Further, subgroup analyses stratified based on case proved that the ACE D allele demonstrated an association with increasing risk of COVID-19 severity (D vs. I: [Formula: see text], 95% [Formula: see text]; DD vs. II: [Formula: see text], 95% [Formula: see text]; DI vs. II: [Formula: see text], 95% [Formula: see text]; dominant model: [Formula: see text], 95% [Formula: see text]; and recessive model: [Formula: see text], 95% [Formula: see text]). Conclusions. The ACE D allele was clearly related to an enhanced risk of COVID-19 severity. Hence, it is imperative to take into account the influence of genetic factors during the development of future vaccines.

Luoyi et al. (2023) conducted a meta-analysis in COVID-19 (n=5,674). ACE I/D polymorphism (D allele) vs. ACE II genotype / I allele was evaluated on COVID-19 risk and severity. The ACE D allele was not associated with overall COVID-19 risk but was clearly related to an enhanced risk of COVID-19 severity.
