Abstract

Introduction

The role of Angiotensin-converting enzyme (ACE and ACE2) phenotypes and polymorphisms in modulating severe acute respiratory syndrome coronavirus (SARS-CoV2) infection in hypertensive patients remains unclear. Our objective was to determine the distribution of ACE and ACE2 receptor phenotypes by patient demographics and correlate ACE and ACE2 levels of activity with SARS-CoV-2 outcomes.

Methods

Hypertensive patients treated for SARS-CoV-2 at an urban emergency department (ED) were prospectively enrolled in a cohort study between August 2020 and April 2021. Blood samples were collected during ED visits or hospitalization. Outcome measures including hospitalization, intensive care unit (ICU) admission, and 30-day mortality were obtained from electronic health records. Multivariable logistic regression was used.

Results

Of the 150 patients enrolled, 60% were Black, 32% Hispanic/Latinx, 4% Non-Hispanic Whites, and 4% others. The mean age was 59 (+/-14) years. The rate of hospitalization was high (86%) and Hispanic/Latinx had a higher likelihood of ICU admission. Patients harboring the rs2285666 genotype TT, AA, and GC alleles were more likely to be admitted to ICU, and those with TT and AA had higher mortality. The ACE level was a significant predictor of hospitalization with a protective effect in both unadjusted and adjusted results. Hispanics/Latinx had a four times higher likelihood of ICU admission compared to all others, and age was significantly associated with 30-day mortality.

Conclusion

Our results show that even after adjusting for age, race, and sex, ACE levels remained a predictor of hospitalization. ACE/ACE2 phenotypes and genotypes potentially play an important role in disease progression in SARS-CoV-2 patients.
