Alexander DP, Nickman NA, Chhibber A, Stoddard GJ, Biskupiak JE, Munger MA. Angiotensin-converting enzyme inhibitors reduce community-acquired pneumonia hospitalization and mortality. Pharmacotherapy 2022; 42:890-897. [PMID: 36278479 DOI: 10.1002/phar.2739] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Revised: 10/14/2022] [Accepted: 10/14/2022] [Indexed: 11/13/2022]
Abstract
BACKGROUND Pneumonia is a global disorder and a common reason for prolonged hospitalization. Angiotensin-converting enzyme inhibitors (ACEi) have pleiotropic effects that support a role in modulating pneumonia, but results have been controversial. OBJECTIVES The present study was conducted to elucidate an ACEi-induced pneumonia benefit in at-risk neurologically impaired population and to determine whether a mortality benefit exists. METHODS A cohort study using a large health-system of 29,011 unique ACEi users and 1635 case patients 65 years of age or older without neurological disorders affecting swallowing who were admitted with community-acquired pneumonia hospitalization and followed up from January 1, 2015 to December 31, 2019 (5 years). The association between ACEi use and pneumonia hospitalization and mortality were determined after propensity score matching using Cox and logistic regression. RESULTS The experimental cohort was 74.9 ± 7.3 years and 51% were male. ACEi users had lower odds of acquiring pneumonia versus ACEi non-users (odds ratio) 0.72 [95% Confidence Interval (CI) 0.51 to 0.99]; p = 0.048. The risk of short-term mortality (<30 days) (HR) 0.42, p < 0.001 and long-term mortality (≥30 day) (HR) 0.83, p < 0.002 was significantly lower for ACEi users compared with the ACEi non-users. CONCLUSIONS ACEi use in patients at risk of pneumonia without neurological swallowing disorders is associated with reduction in hospitalization and lowering of short- and long-term mortality. Given the high incidence of morbidity and mortality associated with pneumonia, and the susceptibility in older populations with underlying cardiovascular or renal disease or social dependencies, our data support the prescribing of ACEi in these populations to reduce pneumonia hospitalization risk as well as short- and long-term mortality.

Association between Antihypertensive Therapy and Risk of Acute Lower Respiratory Infections (ALRI): A Retrospective Cohort Study. Healthcare (Basel) 2022; 10:healthcare10112318. [PMID: 36421642 PMCID: PMC9690450 DOI: 10.3390/healthcare10112318] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 11/10/2022] [Accepted: 11/14/2022] [Indexed: 11/22/2022] Open
Abstract
Purpose: The aim of this study was to analyze the association between antihypertensive drugs and the incidence of acute lower respiratory infections in patients treated in general practices in Germany. Methods: After propensity score matching of five antihypertensive drug classes, a total of 377,470 patients aged ≥18 years were available for analysis. The association between each antihypertensive drug class and ALRI incidence as compared to all other antihypertensive drug classes (as a group) was studied using conditional Cox regression analyses. Because of multiple comparisons and large patient samples, findings were clinically considered relevant when the hazard ratio was <0.85 or >1.15. Results: The regression analyses applied found no clinically relevant associations between antihypertensive drugs and the incidence of acute lower respiratory infections, as all hazard ratios were between 0.85 and 1.15. Conclusion: In the present study, only slight and not clinically relevant increases or decreases in the ALRI incidence were observed. Additional studies are necessary to further explore the risks associated with antihypertensive agents that are widely embedded in today’s clinical practice.

The Association Between Antihypertensive Drug Use and Hospitalization for Pneumonia in the General Population: A Case-Crossover Study Using the National Health Insurance Database of Korea. J Korean Med Sci 2022; 37:e248.

Abstract
BACKGROUND Previous studies have reported an association between pneumonia risk and the use of certain drugs. We investigated the relationship between antihypertensive drugs and pneumonia in the general population. METHODS This case-crossover study utilized the nationwide data of South Korea. We included participants who were hospitalized for pneumonia. A single case period was defined as 30 days before pneumonia onset, and two control periods were established (90-120 and 150-180 days before pneumonia onset). Further, we performed sensitivity and subgroup analyses (according to the presence of diabetes, documented disability, and whether participants were aged ≥ 70 years). We used conditional logistic regression models adjusted for covariates, such as angiotensin-converting-enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), other antihypertensives, statins, antipsychotics, benzodiazepine, and the number of outpatient visits. RESULTS In total, 15,463 subjects were included in this study. ACE inhibitors (adjusted odds ratio [aOR], 0.660; 95% confidence interval [CI], 0.558-0.781), ARBs (aOR, 0.702; 95% CI, 0.640-0.770), and other antihypertensive drugs (aOR, 0.737; 95% CI, 0.665-0.816) were significantly associated with reduced pneumonia risk. Subgroup analyses according to the presence of diabetes mellitus, documented disability, and whether participants were aged ≥ 70 years consistently showed the association of antihypertensives with a reduced risk of hospitalization for pneumonia. CONCLUSION All antihypertensive drug types were related to a lower risk of hospitalization for pneumonia in the general population. Our results implied that frequent medical service usage and protective immunity were primarily related to a reduced risk of pneumonia in the general population of South Korea.

Abstract
BACKGROUND It is controversial whether angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEI/ARB) have a potentially beneficial role in the respiratory system. This study investigated the association between ACEI/ARB medications and respiratory-related mortality in hypertensive patients in a real-world nationally representative cohort. METHODS This was a retrospective analysis based on a prospective cohort study. A total of 10,530 patients with hypertension aged ≥ 20 years were included. The data was extracted from the US National Health and Nutrition Examination Survey during 1988-1994 and 1999-2006. The study was approved by the Institutional Review Boards. Moreover, inform concent was taken form all the participants. RESULTS Overall, 27.7% (n = 2920) patients took ACEI/ARB agents. During a median follow-up of 12.4 years, 278 individuals died of respiratory disease, including chronic lower respiratory disease (n = 155) and influenza or pneumonia (n = 123). Compared with the patients without ACEI/ARB use, those taking ACEI/ARB were not associated with respiratory-specific mortality in a multivariable-adjusted Cox model. After 1: 1 matching, taking ACEI/ARB was also not related to respiratory mortality (Hazard ratio (HR) = 1.07, 95% CI: 0.79-1.43), influenza- or pneumonia-related (HR = 1.00, 95% CI: 0.65-1.54) and chronic pulmonary mortality (HR = 1.13, 95% CI: 0.75-1.69). After separating ACEI and ARB from anti-hypertensive medications, those associations remained unchanged. CONCLUSIONS We discovered no significant link between ACEI or ARB medication and pulmonary-related mortality in hypertensive patients. In hypertensive patients, standard ACEI/ARB administration may have little effect on the respiratory system.

Abstract
BACKGROUND We aimed to examine the association between antihypertensive use and the incidence of hospitalized pneumonia in patients with a history of stroke. METHODS In this case-crossover study, we obtained data from the Korean National Health Insurance Service-National Sample Cohort database. We included the data of patients with history of stroke who were admitted with a disease code of pneumonia. We analyzed the patients' exposure to antihypertensives in the 30 (single case period), 90-120, and 150-180 days (2 control periods) before the onset of pneumonia using conditional logistic regression analysis. Additionally, sensitivity analysis and subgroup analysis according to diabetes status, age, and documented disability were performed. RESULTS Angiotensin II receptor blocker (ARB) use was associated with a reduced risk of hospitalized pneumonia (adjusted odds ratio [OR] [95% confidence interval; 95% CI]: 0.718 [0.576-0.894]). However, the use of angiotensin converting enzyme inhibitors and other antihypertensives were not associated with a change in hospitalized pneumonia incidence (adjusted OR [95% CI]: 0.902, [0.603-1.350] and 0.788 [0609-1.018], respectively). Subgroup analysis revealed that ARB use was associated with a reduced incidence of hospitalized pneumonia in patients with a history of stroke who were older than 65 years, but not in younger (≤ 65 years) group (adjusted OR [95% CI]: 0.687 [0.536-0.880]). CONCLUSION ARB use is associated with a reduced incidence of hospitalized pneumonia in patients with a history of stroke, especially in older adults.

Abstract
BACKGROUND Few large-scale cohort studies have investigated the association between community-acquired pneumonia and the use of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs). We aimed to study whether using ACEIs or ARBs had protective effects for community-acquired pneumonia. METHODS This database cohort study was conducted retrospectively in Taiwan. The hypertensive patients were the target population of this study. Patients with ARB use were defined as our first study cohort. The second study cohort comprised patients who used ACEI. Propensity-score matching at 1:1 was used between ARB users and non-ARB users. We recruited 67 944 participants for the ARB study and 58 062 participants for the ACEI study. The same matching was also performed between ACEI users and non-ACEI users. Cox proportional hazard regression was used to analyse the risk of the outcome of viral pneumonia. RESULTS The hazard ratio of community-acquired pneumonia for ARB users relative to non-ARB users was 0.33. The hazard ratio of community-acquired pneumonia was 0.71 times in ACEI users compared with ACEI nonusers. In stratification analysis, both ARB and ACEI both exhibited a protective effect for community-acquired pneumonia in each age and sex group. In the analysis of the effects of therapy duration, patients using ARB for fewer than 100 days exhibited a greater reduction in the risk of community-acquired pneumonia (adjusted HR = 0.58) compared with the non-ARB cohort. For the ACEI study, patients who used ACEI for 121-450 days were more likely to exhibit reduced risks of community-acquired pneumonia (adjusted HR = 0.5). CONCLUSION Both ACEI and ARB uses were associated with decreased risk of community-acquired pneumonia infection.

Br J Clin Pharmacol 2021; 87:2475-2492. [PMID: 33217033 PMCID: PMC7753617 DOI: 10.1111/bcp.14660] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 10/28/2020] [Accepted: 11/10/2020] [Indexed: 02/06/2023] Open
Abstract
AIMS Angiotensin-converting enzyme-2 (ACE2) is the receptor for SARS-CoV-2. Animal studies suggest that renin-angiotensin-aldosterone system (RAAS) blockers might increase the expression of ACE2 and potentially increase the risk of SARS-CoV-2 infection. METHODS AND RESULTS The effect of ACE inhibitor (ACEI) treatment on the pneumonia incidence in non-COVID-19 patients (25 studies, 330 780 patients) was associated with a 26% reduction of pneumonia risk (odds ratio [OR]: 0.74, P < .001). Pneumonia-related death cases in ACEI-treated non-COVID-19 patients were reduced by 27% (OR: 0.73, P = .004). However, angiotensin II receptor blockers (ARB) treatment (10 studies, 275 621 non-COVID-19 patients) did not alter pneumonia risk in patients. Pneumonia-related death cases in ARB-treated non-COVID-19 patients was analysed only in 1 study and was significantly reduced (OR, 0.47; 95% confidence interval, 0.30 to 0.72). Results from 11 studies (8.4 million patients) showed that the risk of getting infected with the SARS-CoV-2 virus was reduced by 13% (OR: 0.87, P = .014) in patients treated with ACEI, whereas analysis from 10 studies (8.4 million patients) treated with ARBs showed no effect (OR, 0.92, P = .354). Results from 34 studies in 67 644 COVID-19 patients showed that RAAS blockade reduces all-cause mortality by 24% (OR = 0.76, P = .04). CONCLUSION ACEIs reduce the risk of getting infected with the SARS-CoV-2 virus. Blocking the RAAS may decrease all-cause mortality in COVID-19 patients. ACEIs also reduce the risk of non-COVID pneumonia. All-cause mortality due to non-COVID pneumonia is reduced by ACEI and potentially by ARBs.

Abstract
COVID-19 has caused worldwide death and economic destruction. The pandemic is the result of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which has demonstrated high rates of infectivity leading to great morbidity and mortality in vulnerable populations. At present, scientists are exploring various approaches to curb this pandemic and alleviate its health consequences, while racing to develop a vaccine. A particularly insidious aspect of COVID-19 is the delayed overactivation of the body's immune system that is manifested as the cytokine storm. This unbridled production of pro-inflammatory cytokines and chemokines can directly or indirectly cause massive organ damage and failure. Systemic vascular endothelial inflammation and thrombocytopenia are potential consequences as well. In the case of COVID-19, the cytokine storm often fits the pattern of the macrophage activation syndrome with lymphocytopenia. The basis for the imbalance between the innate and adaptive immune systems is not clearly defined, but highlights the effect of SARS-CoV-2 on macrophages. Here we discuss the potential underlying basis for the impact of SARS-CoV-2 on macrophages, both direct and indirect, and potential therapeutic targets. These include granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin 6 (IL-6), interferons, and CXCL10 (IP-10). Various biopharmaceuticals are being repurposed to target the cytokine storm in COVID-19 patients. In addition, we discuss the rationale for activating the macrophage alpha 7 nicotinic receptors as a therapeutic target. A better understanding of the molecular consequences of SARS-CoV-2 infection of macrophages could lead to novel and more effective treatments for COVID-19.

Abstract
The effects of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) on the risk of COVID-19 infection and disease progression are yet to be investigated. The relationship between ACEI/ARB use and COVID-19 infection was systematically reviewed. To identify relevant studies that met predetermined inclusion criteria, unrestricted searches of the PubMed, Embase, and Cochrane Library databases were conducted. The search strategy included clinical date published until May 9, 2020. Twelve articles involving more than 19,000 COVID-19 cases were included. To estimate overall risk, random-effects models were adopted. Our results showed that ACEI/ARB exposure was not associated with a higher risk of COVID-19 infection (OR = 0.99; 95 % CI, 0-1.04; P = 0.672). Among those with COVID-19 infection, ACEI/ARB exposure was also not associated with a higher risk of having severe infection (OR = 0.98; 95 % CI, 0.87-1.09; P = 0.69) or mortality (OR = 0.73, 95 %CI, 0.5-1.07; P = 0.111). However, ACEI/ARB exposure was associated with a lower risk of mortality compared to those on non-ACEI/ARB antihypertensive drugs (OR = 0.48, 95 % CI, 0.29-0.81; P = 0.006). In conclusion, current evidence did not confirm the concern that ACEI/ARB exposure is harmful in patientswith COVID-19 infection. This study supports the current guidelines that discourage discontinuation of ACEIs or ARBs in COVID-19 patients and the setting of the COVID-19 pandemic.

Angiotensin converting enzyme 2 (ACE2) is the recognized host cell receptor responsiblefor mediating infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). ACE2bound to tissue facilitates infectivity of SARS-CoV-2; thus, one could argue that decreasing ACE2tissue expression would be beneficial. However, ACE2 catalytic activity towards angiotensin I (AngI) and II (Ang II) mitigates deleterious effects associated with activation of the renin-angiotensinaldosteronesystem (RAAS) on several organs, including a pro-inflammatory status. At the tissuelevel, SARS-CoV-2 (a) binds to ACE2, leading to its internalization, and (b) favors ACE2 cleavage toform soluble ACE2: these actions result in decreased ACE2 tissue levels. Preserving tissue ACE2activity while preventing ACE2 shredding is expected to circumvent unrestrained inflammatoryresponse. Concerns have been raised around RAAS modulators and their effects on ACE2expression or catalytic activity. Various cellular and animal models report conflicting results invarious tissues. However, recent data from observational and meta-analysis studies in SARS-CoV-2-infected patients have concluded that RAAS modulators do not increase plasma ACE2 levels orsusceptibility to infection and are not associated with more severe diseases. This review presentsour current but evolving knowledge of the complex interplay between SARS-CoV-2 infection, ACE2levels, modulators of RAAS activity and the effects of RAAS modulators on ACE2 expression.

Abstract
Angiotensin-converting enzyme (ACE) inhibitors and statins may potentially benefit patients with viral infections and pneumonia. Our study aimed to evaluate the impact of ACE inhibitors and statins on the rates of intubation and death in viral pneumonia. We retrospectively studied 1055 adult patients admitted to a tertiary care center in central Texas with a positive respiratory viral polymerase chain reaction test. Of these, 539 had clinical presentation and imaging consistent with pneumonia. We collected information on demographic characteristics, microbiology, comorbid conditions, medication use, and outcomes. ACE inhibitors given prior to admission were associated with an increased risk of death or intubation (odds ratio [OR] = 3.02; 95% confidence interval [CI], 1.30-7.01), whereas statin use prior to admission did not change rates of death or intubation. Lower rates of death and intubation were noted with continued use of ACE inhibitors (OR =0.25; 95% CI, 0.09-0.64) and statins (OR =0.26; 95% CI, 0.08-0.81) throughout the hospital stay. We added further evidence of the beneficial effect of continued use of ACE inhibitors and statins in viral pneumonia.

Abstract
Objectives This study aimed to compare the effects of angiotensin-converting-enzyme inhibitors (ACEis) and angiotensin receptor blockers (ARBs) on the risk of pneumonia and severe exacerbations in patients with COPD. Patients and methods All patients with COPD who used ACEis and ARBs for >90 days between 2000 and 2005 were recruited. Pairwise matching (1:1) of the ACEi and ARB groups resulted in two similar subgroups, with 6,226 patients in each. The primary outcomes were pneumonia and COPD exacerbations, and the secondary outcome was death. Results During the follow-up period, the incidence of pneumonia was 7.20 per 100 person-years in the ACEi group and 5.89 per 100 person-years in the ARB group. The ACEi group had a higher risk of pneumonia (adjusted hazard ratio [aHR], 1.22; 95% CI, 1.15–1.29) than the ARB group. The incidence of severe exacerbations was 0.65 per person-year for the patients receiving ACEis and 0.52 per person-year for those receiving ARBs. The patients receiving ACEis had a higher risk of severe exacerbations (aHR, 1.19; 95% CI, 1.16–1.21) than those receiving ARBs. Similar trends were noted in terms of severe exacerbations requiring hospitalization (aHR, 1.24; 95% CI, 1.21–1.28) or emergency department visits (aHR, 1.16; 95% CI, 1.13–1.18), pneumonia requiring mechanical ventilation (aHR, 1.35; 95% CI, 1.24–1.47), and mortality (aHR, 1.33; 95% CI, 1.26–1.42). Conclusion ARBs were associated with lower rates of pneumonia, severe pneumonia, and mortality than ACEis in patients with COPD.

Abstract
BACKGROUND The hallmark of COPD is chronic airway inflammation, which may be mediated by renin-angiotensin system. The renin-angiotensin system blockers such as angiotensin-converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARBs) have exhibited anti-inflammatory and immunomodulatory effects in patients with various diseases. We explored the effects of ACEi and ARBs on the risk of pneumonia in patients with COPD. METHODS A nested case-control study was performed on COPD patients recruited from January 2010 to August 2013 in two referral hospitals in Korea. A total of 130 COPD patients admitted with pneumonia were included, and 245 COPD patients without pneumonia were selected as controls from a total of 1,646 such patients. Controls were matched with test patients by age, sex, and severity of airflow limitation. The effects of ACEi/ARBs use on the odds ratio (OR) for the development of pneumonia were tested through conditional logistic regression. RESULTS Elderly patients (over 70 years of age) constituted ~30% of each group; most of the patients were male (85%). Of the COPD patients with pneumonia, 21.5% had taken ACEi/ARBs for a mean of 9.8 months (standard deviation ±3.5 months). The proportions of ACEi/ARBs users and the mean duration of such use did not differ when compared to those of the control patients (26.9%, P=0.25; 9.6±3.6 months, P=0.83). Univariate analyses indicated that the use of ACEi/ARBs was not associated with a decreased risk of pneumonia (OR =0.70, 95% confidence interval 0.41-1.23, P=0.21), whereas both a history of pulmonary tuberculosis (OR =1.85, 95% confidence interval 1.12-3.06, P=0.02) and exposure to systemic steroids (OR =2.33, 95% confidence interval 1.28-4.23, P=0.005) did show an association. After adjustment for a history of tuberculosis, comorbid chronic renal disease, and exposure to corticosteroids, ACEi/ARBs reduced the risk of pneumonia in COPD patients (OR =0.51, 95% confidence interval 0.27-0.98, P=0.04). CONCLUSION This study revealed that the use of ACEi/ARBs was associated with reducing the risk of pneumonia in patients with COPD. Further prospective studies are necessary to confirm the protective effect of ACEi/ARBs and elucidate the underlying mechanisms in COPD patients.

Abstract
Renin and aldosterone activity levels are low in elderly patients, raising concerns about the benefits and risks of angiotensin-converting-enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARB) use. However, data from direct comparisons of the effects of ACEIs on ARBs in the elderly population remain inconclusive.In this nationwide study, all patients aged ≥ 70 years were retrieved from the Taiwan National Health Insurance database for the period 2000 to 2009 and were followed up until the end of 2010. The ARB cohort (12,347 patients who continuously used ARBs for ≥ 90 days) was matched to ACEI cohort using high-dimensional propensity score (hdPS). Intention-to-treat (ITT) and as-treated (AT) analyses were conducted.In the ITT analysis, after considering death as a competing risk, the ACEI cohort had similar risks of myocardial infarction (hazard ratio [HR] 0.92, 95% confidence interval [CI] 0.79-1.06), ischemic stroke (HR 0.98, 95% CI 0.90-1.07), and heart failure (HR 0.93, 95% CI 0.83-1.04) compared with the ARB cohort. No difference in adverse effects, such as acute kidney injury (HR 0.99, 95% CI 0.89-1.09) and hyperkalemia (HR 1.02, 95% CI 0.87-1.20), was observed between cohorts. AT analysis produced similar results to those of ITT analysis. We were unable to demonstrate a survival difference between cohorts (HR 1.03, 95% CI 0.88-1.21) after considering drug discontinuation as a competing risk in AT analysis.Our study supports the notion that ACEI and ARB users have similar risks of major adverse cardiovascular events (MACE), even in elderly populations.

Abstract
Background Pharmacoepidemiologic analysis can confirm whether drug efficacy in a randomized controlled trial (RCT) translates to effectiveness in real settings. We examined methods used to control for immortal time bias in an analysis of renin–angiotensin system (RAS) inhibitors as the reference cardioprotective drug. Methods We analyzed data from 3928 patients with type 2 diabetes who were recruited into the Hong Kong Diabetes Registry between 1996 and 2005 and followed up to July 30, 2005. Different Cox models were used to obtain hazard ratios (HRs) for cardiovascular disease (CVD) associated with RAS inhibitors. These HRs were then compared to the HR of 0.92 reported in a recent meta-analysis of RCTs. Results During a median follow-up period of 5.45 years, 7.23% (n = 284) patients developed CVD and 38.7% (n = 1519) were started on RAS inhibitors, with 39.1% of immortal time among the users. In multivariable analysis, time-dependent drug-exposure Cox models and Cox models that moved immortal time from users to nonusers both severely inflated the HR, and time-fixed models that included immortal time deflated the HR. Use of time-fixed Cox models that excluded immortal time resulted in a HR of only 0.89 (95% CI, 0.68–1.17) for CVD associated with RAS inhibitors, which is closer to the values reported in RCTs. Conclusions In pharmacoepidemiologic analysis, time-dependent drug exposure models and models that move immortal time from users to nonusers may introduce substantial bias in investigations of the effects of RAS inhibitors on CVD in type 2 diabetes.
