We sought to assess the risk of hospitalization for COVID-19 and serious complications in current users of ARB or ACEi compared to users of dihydropyridine calcium channel blockers (dhpCCB). Design: Cohort study Setting: The analysis used de-identified, patient-level data from HealthVerity, linking longitudinal data from US medical and pharmacy claims, which contain information on inpatient or outpatient diagnoses, procedures and medication dispensing. Participants: We identified patients aged 40+ and free of chronic kidney disease (CKD) who were newly diagnosed COVID-19, between March 1, 2020 and May 30, 2020, and adherent to ACEi, ARB, or dhpCCB therapy. Interventions: Current use of an ACEi, ARB, or dhpCCB. Main outcome measures: We compared the 30-day risk of hospitalization for COVID-19 and serious complications. Results: Of 24,708 patients identified, 7,571 were current users of an ARB, 8,484 of an ACEi, and 8,653 of a dhpCCB. The unadjusted 30-day risk of hospitalization for COVID-19 was 2.66% among ARB users, and 2.90% among ACEi users and 3.68% in dhpCCB users. In the PS-matched cohort, the risk of hospitalization among ARB users was 17% lower as compared to dhpCCB (RR=0.83; 0.68-1.00), and the risk among ACE users was 10% lower as compared to dhpCCB (RR=0.90; 0.76-1.07). When including patients with pre-existing CKD, the protective effect of ARB (RR= 0.74; 0.62-0.88) and ACEi (RR=0.84; 0.71-0.99) was more pronounced. Conclusions: This cohort study showed that neither ARB nor ACEi use increase the risk of severe COVID-19 disease among those infected, and instead suggests that current use of ARB may offer a protective effect. This study found no evidence to support the discontinuation of ARB/ACEi therapy. the topic of this study. He is a consultant to Aetion, a software manufacturer of which he owns equity.

The spike proteins covering SARS-COV-2 bind to angiotensin-converting enzyme-2 (ACE2) receptors primarily on type II alveolar cells and cells in the heart, kidney, liver, and gastrointestinal tract, enabling the virus to inject its RNA. 1 It has been hypothesized that blocking the ACE2 receptor may decrease SARS-COV-2's ability to bind to human cells, and thus reduce the severity of COVID-19 illness. 1 However, there is uncertainty surrounding the effect of renin-angiotensin-aldosterone system (RAAS) inhibition in patients with COVID-19, with some hypothesizing that angiotensin receptor blockers (ARB) or angiotensin converting enzyme inhibitors (ACEi) use may increase the propagation of the virus. [1] [2] [3] [4] Any link between ACEi or ARB use and the virus RNA's ability to enter human cells could yield an effect, positive or negative, on the clinical severity of a COVID-19 infection, including the need for hospitalization, ventilator use, intensive care unit (ICU) stay, or death. Pre-published cohort studies by Giorgi, Mehta, and Rentsch examined the use of ACEi/ARB with respect to hospital admissions and found an increased risk; however, the contrast they made compared ACEi/ARB users to nonusers and likely did not fully account for underlying factors associated with both the need for ACE or ARB treatment and with poor health outcomes. [5] [6] [7] Khera et al. addressed some of these issues by equalizing risk through requiring comparator patients to have hypertension and to be treated with a guideline-recommended antihypertensive, and found a protective effect with ACEi use, but not ARB use, among Medicare beneficiaries. 8 The literature lacks study findings examining the use of ACEi or ARB therapy across a broad population, and the associated risk of severe outcomes from COVID-19. 4 As such, clinicians lack clear guidance on appropriate action to take with patients using an ACEi or ARB and diagnosed with COVID-19, in particular whether to discontinue therapy. To that end, this study compares the risk of hospitalization for COVID-19 disease and hospitalization for serious complications of COVID-19 among prevalent users of ACEi or ARB as compared with prevalent users of dihydropyridine calcium channel blockers (dhpCCB), using recently-collected administrative claims data from the US. This study used de-identified patient level healthcare data from HealthVerity covering >100 million unique patients with data from over 60 unique data sources in the US, including medical claims, pharmacy claims, lab, and electronic medical records (EMR). Data encompass all major US payer types, including commercial, Medicaid, and Medicare. For this study, we examined linked medical claims, pharmacy claims, and laboratory data containing diagnoses, procedures, prescriptions and other variables. Claims included both unadjudicated insurance claims available in near real-time time from practice management systems, billing systems, and claims clearinghouses which were then linked with adjudicated claims sourced from insurance providers and payers as well as laboratory data from hospital billing systems. Data for this study covered the period of December 1, 2018 through May 30, 2020. Claims include dates of service and diagnoses, and are recorded longitudinally, thus allowing us to establish baseline health status, COVID-19 diagnosis, and any sequalae. This study was approved by the New England IRB (#1-9757-1). De-identified patient level study data can be made available for inspection. Eligible patients had at least one medical encounter related to COVID-19. A COVID-19-related encounter was defined as any claim with an International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) code in accordance with the Center for Disease Control's (CDC) interim (B34.2, B97.21, B97.29, J12.81) and final (U07.1) coding guidance for confirmed cases of COVID-19 a or who had a positive or presumed positive COVID-19 viral lab test between March 1, 2020 and May 30, 2020 (see Appendix A for further details). To compare the impact of ongoing ACEi or ARB therapy on severity of COVID-19 infection, we implemented a prevalent user, active comparator design where balance between treatment groups at baseline was achieved through study design and propensity score (PS) matching. 9,10 A prevalent user design, where all study participants were using one of the study medications prior to the index date, was chosen in order to understand the effect of medications being taken at the time of COVID-19 infection, rather than the effect of initiation of therapy in response to COVID-19 diagnosis. To improve comparability among treatment groups, prevalent users of a dhpCCB were selected as the active comparator; these agents are also an anti-hypertensive treatment, like ACEi and ARB, yet due to their different mechanism of action, have no hypothesized effect on COVID-19. We created 2 cohorts for analysis: cohort 1 included prevalent users of ARB versus dhpCCB, and cohort 2 included prevalent users of ACEi versus dhpCCB. Cohort entry was defined as the first outpatient visit with a COVID-19 diagnosis among patients with at least one prescription for an ACEi, ARB, or dhpCCB within the 90 days before cohort entry. We excluded patients if they: (1) had no other medical or pharmacy claims activity in the 90 days prior to cohort entry, (2) qualified for more than one treatment category, (3) were of age less than 40 years on cohort entry, or (4) had a diagnosis of chronic kidney disease (CKD) within the 90 days prior to cohort entry, as CKD is a contraindication for use of an ACEi or ARB (though not for dhpCCB). We conducted a sensitivity analysis that included patients with pre-existing CKD. We compared the risk of (1) hospitalization for COVID-19 and (2) hospitalization for serious COVID-19 complications in the 30 days following cohort entry. We identified hospitalization for COVID-19 as the first inpatient visit with a diagnosis of COVID-19 (ICD-10 code: U07.1) following CDC-defined outpatient diagnosis of COVID-19. We identified hospitalization for serious COVID-19 complications as the first inpatient visit with a diagnosis of COVID-19, as above, followed on the same day or within 30 days by a diagnosis code for acute organ dysfunction or failure, acute respiratory distress syndrome (ARDS), sepsis, or respiratory intubation or mechanical ventilation (see Appendix B for a full list of codes). Follow-up started the day after cohort entry and continued until the earliest of occurrence of outcome, death, disenrollment, 30 days, or the end of data (May 30, 2020). For each patient, we recorded age at cohort entry, sex, and month of cohort entry. Over the 90 days prior to cohort entry, we assessed: history of pneumonia infection requiring an office visit or hospitalization, prior use of asthma medications or anticoagulants, number of physician visits, number of unique prescription medications filled, and a range of comorbidities that may be risk factors for more severe COVID-19 disease ( Table 2) . Comorbidities included malignancy, alcohol use disorder, coagulation deficiency, HIV or AIDS, paralysis, valvular heart disease, weight loss, overweight or obesity, smoking, acute coronary syndrome, arrythmias, asthma, chronic pulmonary disease, conduction disorders, congestive heart failure, dependence on supplemental oxygen, hematologic disorders, hypertension, inflammatory heart disease, ischemic heart disease, liver disease, myocardial infarction, stroke, pulmonary circulation disorders, rheumatic disease, and systemic lupus erythematosus. We tabulated baseline patient characteristics and assessed the 30-day risk of the outcomes of interest with 95% confidence intervals for each exposure group. To account for potential confounding by measured patient characteristics, we used propensity score (PS)-matching to achieve balance of covariates between the treatment groups. 11,12 While a prevalent user analysis can lead to bias from adjusting for intermediate variables, 13 in this case both the drug exposure and the patient characteristics were observed before cohort entry, and thus are unlikely to cause bias. The PS, defined as the probability that a patient was using either ACEi/ARB versus dhpCCB, conditioning on all the confounders listed above, was estimated with a multivariable logistic regression model. PS-matching was performed using 1:1 nearest neighbor matching with a maximum matching caliper of 0.02 on the PS scale. 14 To quantify balance achieved at baseline, we computed standardized differences in the covariates between the two groups after PS-matching. 15 We calculated relative risks (RR) and 95% confidence intervals (CIs) of the outcomes associated with drug use using logistic regression. All analyses were conducted using the Aetion Evidence Platform v3.19 (including R version 4.0.2), which has been validated and has successfully predicted randomized control trial findings. [16] [17] [18] All analyses from the raw patient-level data are recorded with audit trails and can be reviewed on request. We identified 24,708 patients aged 40 years or older who had an outpatient diagnosis of COVID-19 and met the inclusion criteria (Table 1) In the PS-matched cohort, the 30-day risk of hospitalization for COVID-19 was 2.85% in ARB users (vs. 3.44% in dhpCCB users) and 3.12% in ACEi users (vs. 3.46% in dhpCCB users) ( In our sensitivity analysis including patients with pre-existing CKD in the 90 days before outpatient COVID-19 diagnosis, the relative risk of hospitalization for COVID-19 decreased to 0.74 (0.62-0.88) for ARB and 0.84 (0.71-0.99) for ACEi. In this population-representative study of patients aged 40 and older with an outpatient COVID-19 diagnosis, we observed a 17% decrease in the 30-day risk of hospitalization for COVID-19 among ARB users compared to dhpCCB users, and a 10% decrease in risk of hospitalization for COVID-19 among ACEi users compared to dhpCCB users. We also observed a numerically decreased 30-day risk of respiratory intubation and mechanical ventilation after hospitalization with COVID-19 among ARB users compared to dhpCCB users. There was no meaningful difference in the risk of acute organ dysfunction, ARDS, or sepsis among RAAS inhibitors vs. dhpCCBs. Our findings suggest neither a need to discontinue ACEi/ARB therapy among patients using those medications at the time of COVID-19 diagnosis, nor a clear case for use of ACEi/ARB therapy as prophylaxis among COVID-19-infected patients. There were several notable strengths of this study. First, we used a large population-representative cohort with over 20,000 COVID-19 adults 40+ receiving anti-hypertensive treatment with RAAS inhibitors or dhpCCB from established data sources. Second, the outcome of interest was severe enough to avoid differential surveillance bias since all serious infections that require hospitalization are captured in claims data, and the ICD codes used to identify them have been shown to be of high accuracy. 20 Third, we implemented robust adjustment for potential confounders using active comparator study design combined with 1:1 propensity score matching. 21,22 Fourth, by requiring comparator patients also be treated with an antihypertensive medication, the confounder-adjusted, dhpCCB control group provided an appropriate reference value for hospitalization in patients aged 40 or older with COVID-19 infection . This population-based study applying a causal study design concludes that neither ARB nor ACEi use increase the risk of severe COVID-disease among those infected, and rather suggest that prevalent use of these medications -ARB in particular --may offer a protective effect. Indeed, our findings suggest a small decrease in risk of hospitalization for COVID-19 between adult patients with an outpatient COVID-19 diagnosis who were using RAAS inhibitors versus those treated with dhpCCB. These findings are reassuring as they suggest that RAAS inhibitors should not be discontinued among patients with COVID-19 infection.
