Introduction: Diabetes mellitus and hypertension are described as the most common comorbidities among COVID-19 patients. We investigated the adverse effect of ACEIs in diabetic and nondiabetic patients with COVID-19.
Methods: This prospective study consisted of 617 RT-PCR-confirmed COVID-19 inpatients. Demographic and baseline characteristics, underlying comorbid diseases, and antihypertensive drugs were evaluated. Study outcome (in-hospital death) was evaluated with the Kaplan-Meyer method and Cox regression model. Statistical analyses were performed with SPSS software for Windows. P values < .05 were considered significant.
Results: Mean ± SD age was 58.49 ± 15.80 (range: 18 to 94) years old. Cox regression analysis revealed that age (adjusted hazard ratio [HR] = 1.04, 95% CI: 1.03 to 1.06), diabetes mellitus (adjusted HR = 2.07, 95% CI: 1.32 to 3.26), immunocompromised patients (adjusted HR = 2.33, 95% CI: 1.29 to 4.21), acute kidney injury (AKI) (adjusted HR = 3.23, 95% CI: 2.01 to 5.19), ICU admission (adjusted HR = 2.48, 95% CI: 1.46 to 4.21), Asthma and COPD (adjusted HR = 2.13, CI:1.6 to 4.28) and ACEI (adjusted HR = 3.08, 95% CI: 1.56 to 6.06), respectively were associated with in-hospital death. Among diabetic patients, ACEI (adjusted HR = 3.51, 95% CI: 1.59 to 7.75), AKI (adjusted HR = 3.32, 95% CI: 1.76 to 6.45) and ICU admission (adjusted HR = 3.64, 95% CI: 1.530 to 8.65) were associated with increased mortality. The Kaplan-Meier survival curve showed a lower survival rate in diabetic patients with ACE inhibitor (adjusted HR = 3.36, 95% CI: 2.25 to 7.71).
Conclusion: ACEIs may harm the diabetic patient's outcome with COVID-19. Further studies can confirm if ACE inhibitors have an adverse effect on COVID-19 diabetic patient's mortality.
