ABSTRACT
Submission content Introduction: An unusual case of a very young patient without previously known cardiac disease presenting with severe left ventricular failure, detected by a point of care echocardiogram. Main Body: A 34 year old previously well man was brought to hospital after seeing his general practitioner with one month of progressive shortness of breath on exertion. This began around the time the patient received his second covid-19 vaccination. He was sleeping in a chair as he was unable to lie flat. Abnormal observations led the GP to call an ambulance. In the emergency department, the patient required oxygen 5L/min to maintain SpO2 >94%, but he was not in respiratory distress at rest. Blood pressure was 92/53mmHg, mean 67mmHg. Point of care testing for COVID-19 was negative. He was alert, with warm peripheries. Lactate was 1.0mmol/L and he was producing more than 0.5ml/kg/hr of urine. There was no ankle swelling. ECG showed sinus tachycardia. He underwent CT pulmonary angiography which demonstrated no pulmonary embolus, but there was bilateral pulmonary edema. Troponin was 17ng/l, BNP was 2700pg/ml. Furosemide 40mg was given intravenously by the general medical team. Critical care outreach asked for an urgent intensivist review given the highly unusual diagnosis of pulmonary edema in a man of this age. An immediate FUSIC Heart scan identified a dilated left ventricle with end diastolic diameter 7cm and severe global systolic impairment. The right ventricle was not severely impaired, with TAPSE 18mm. There was no significant pericardial effusion. Multiple B lines and trace pulmonary effusions were identified at the lung bases. The patient was urgently discussed with the regional cardiac unit in case of further deterioration, basic images were shared via a cloud system. A potential diagnosis of vaccination-associated myocarditis was considered,1 but in view of the low troponin, the presentation was felt most likely to represent decompensated chronic dilated cardiomyopathy. The patient disclosed a family history of early cardiac death in males. Aggressive diuresis was commenced. The patient was admitted to a monitored bed given the potential risk of arrhythmia or further haemodynamic deterioration. Advice was given that in the event of worsening hypotension, fluids should not be administered but the cardiac centre should be contacted immediately. Formal echocardiography confirmed the POCUS findings, with ejection fraction <35%. He was initiated on ACE inhibitors and beta adrenergic blockade. His symptoms improved and he was able to return home and to work, and is currently undergoing further investigations to establish the etiology of his condition. Conclusion(s): Early echocardiography provided early evidence of a cardiac cause for the patient's presentation and highlighted the severity of the underlying pathology. This directed early aggressive diuresis and safety-netting by virtue of discussion with a tertiary cardiac centre whilst it was established whether this was an acute or decompensated chronic pathology. Ultrasound findings: PLAX, PSAX and A4Ch views demonstrating a severely dilated (7cm end diastolic diameter) left ventricle with global severe systolic impairment.
ABSTRACT
Aim: People with type 1 or type 2 diabetes have a higher hospital admission rate following Covid-19 infection. This study aims to determine the degree to which the results of a previous study in Greater Manchester (GM) could be replicated in national-level data for England. Method(s): We focussed on the univariable regression analysis, which shows the association between admission and Covid-19 infection in people with diabetes. Modelling was conducted using logistic regression on data from the Covid-IMPACT database. Odds ratios were compared descriptively with the previous study. Result(s): In people with type 2 diabetes, factors associated with an increased risk of hospitalisation similar to the previous study were: older age, male sex, higher social deprivation, higher body mass index (BMI), higher cholesterol, lower eGFR, taking an ACE-inhibitor/ ARB, not taking metformin, and having asthma or hypertension. Patients with COPD, and those taking aspirin or clopidogrel also had increased risk, but the national data showed a greater risk (GM COPD odds ratio 1.89 [1.63-2.19] vs national 2.34 [2.28-2.40] / aspirin 1.49 [1.34-1.66] vs 1.66 [1.63-1.70] / clopidogrel 1.71 [1.47-1.98] vs 1.99 [1.94-2.04]). Similar results were observed in patients with type 1 diabetes. However, due to the increase in sample size, many factors which were previously not statistically significant have become significant, such as in type 2 diabetes BMI, low HDL-cholesterol. Conclusion(s): We have successfully replicated the methods, results and conclusions of our previous study in relation to factors associated with increased risk of hospital admission in diabetes individuals. Regional databases are suitable for large cohort studies, and in this instance produced similar results to a national database, validating our previous findings.
ABSTRACT
Objective: A new generation of vaccine technology platform has been developed to combat the COVID- 19 pandemic, the mRNA vaccine. The EMA granted the Pfizer- BioNTech COVID-19 vaccine an emergency use authorization in December 2020 with limited clinical experience, especially in the pediatric population. Method(s): Here, we present a case-report of a 17-yearold girl, who was vaccinated with the mRNA-COVID vaccine in October 2021, and developed a gross hematuria and proteinuria the day after the vaccination. Result(s): The patient presented at our outpatient clinic three days after the vaccination with new-onset hematuria and proteinuria. Up to this date, she had no former known medical conditions and the family history was negative regarding kidney diseases. We excluded nephrolithiasis, autoimmune glomerulonephritis and urinary tract infection as causes. The laboratory chemistry of the kidney was within normal range. The proteinuria dissolved spontaneously, and a microhematuria persisted. One day after the second dose of Cominarty in November 2021, the gross hematuria with proteinuria relapsed. A treatment with an ACE-inhibitor did not have any effect on the proteinuria. At this point, only a few casereports of patients with a comparable clinical course, especially from Japan, were published. In suspicion of a vaccine-triggered nephritis we started a prednisolon therapy which dissolved the proteinuria and induced a regression of the haematuria to a minimal stage. Conclusion(s): Within the last year, the medical community has gained more insights concerning mRNA vaccines. There is growing evidence, that mRNA vaccines can trigger de novo or relapse IgA nephropathy. But more systematic research and long-term evaluation is desirable to elucidate the underling pathophysiology as well as the influence on kidney survival of affected patients in the future. Furthermore, patient education should incorporate the risk of hematuria and proteinuria in children when applying mRNA vaccines.
ABSTRACT
Introduction In this study, we aimed to monitor anti-spike and anti-nucleocapsid antibodies positivity in healthcare workers (HCWs) vaccinated with two doses of inactivated CoronaVac (Sinovac, China) vaccine. Methods Overall, 242 volunteer HCWs were included. Of the participants, 193 were HCWs without history of prior documented COVID-19 (Group 1), while 49 had history of prior documented COVID-19 before vaccination (Group 2). The participants were followed up for SARS-CoV-2 antibodies positivity at four different blood sampling time points (immediately before the second vaccine dose and at the 1st, 3rd months and 141-150 days after the second dose). We investigated the serum IgG class antibodies against SARS-CoV-2 RBD region and IgG class antibodies against SARS-CoV-2 nucleocapsid antigen by chemiluminescent microparticle immunoassay (CMIA) method using commercial kits. Results We found positive serum anti-RBD IgG antibody in 76.4% of the participants (71% in Group 1;98% in Group 2) 28 days after the first dose. When the antibody levels of the groups were compared at the four blood sampling time points, Group 2 anti-RBD IgG levels were found to be significantly higher than those in Group 1 at all follow-up time points. Although anti-RBD IgG positivity persisted in 95.6% of all participants in the last blood sampling time point, a significant decrease was observed in antibody levels compared to the previous blood sampling time point. Anti-nucleocapsid IgG antibody was positive in 12 (6.2%) of participants in Group 1 and 32 (65.3%) in Group 2 at day 28 after the first dose. At the fourth blood sampling time point, anti-nucleocapsid antibodies were found to be positive in a total of 20 (9.7%) subjects, 10 (6.1%) in Group 1 and 10 (23.8%) in Group 2. Conclusions In this study, it was determined that serum antibody levels decreased in both groups after the third month after the second dose in HCWs vaccinated with CoronaVac vaccine.Copyright © GERMS 2022.
ABSTRACT
BACKGROUND: The pathogenesis of angioedema induced by angiotensin-converting enzyme inhibitors is based on the accumulation of bradykinin as a result of angiotensin-converting enzyme blockade. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) binds to the angiotensin-converting enzyme 2 receptor, which may inhibit its production and thereby lead to an increase in bradykinin levels. Thus, SARS-CoV-2 infection may be a likely trigger for the development of angioedema. AIMS: This study aimed to analyze cases of hospitalizations of patients with angioedema associated with the use of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers during the coronavirus disease 2019 (COVID-19) pandemic. MATERIALS AND METHODS: This study retrospectively analyzed medical records of patients admitted to the Vitebsk Regional Clinical Hospital between May 2020 and December 2020 with isolated (without urticaria) angioedema while receiving angiotensin-converting enzyme inhibitors or angiotensin receptor blockers. In all patients, smears from the naso and oropharynx for COVID-19 were analyzed by polymerase chain reaction. RESULT(S): Fifteen inpatients (9 men and 6 women) aged 44-72 years were admitted because of emergent events, of which 53.6% had isolated angioedema. In two cases, a concomitant diagnosis of mild COVID-19 infection was established with predominant symptoms of angioedema, including edema localized in the face, tongue, sublingual area, and soft palate. All patients had favorable disease outcomes. CONCLUSION(S): Patients with angiotensin-converting enzyme inhibitor-induced angioedema may require hospitalization to monitor upper respiratory tract patency. There were cases of a combination of angiotensin-converting enzyme inhibitor-induced angioedema and mild COVID-19. Issues requiring additional research include the effect of SARS- CoV-2 infection on the levels of bradykinin and its metabolites, the triggering role of COVID-19 in the development of angioedema in patients receiving angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, recommendations for the management of patients with angiotensin-converting enzyme inhibitor-induced angioedema, and a positive result for COVID-19.Copyright © 2020 Pharmarus Print Media All rights reserved.
ABSTRACT
Introduction: Hypertension is the most common co-morbidity associated with COVID-19 patients. Many patients take angiotensin-converting enzyme (ACE) inhibitors for the management of hypertension. The study aimed to compare the clinical and hematologic features in hypertensive and non-hypertensive patients suffering from COVID-19. Material(s) and Method(s): This observational study compared clinical and hematologic features in hypertensive and non-hypertensive patients suffering from COVID-19. The study enrolled patients from SMS Medical College, Jaipur (Rajasthan, India) after approval from the institutional Ethics Committee. The comparison of quantitative variables was performed using the Mann-Whitney test, and qualitative attributes were compared using the chi-squared test. The level of confidence is considered at 5%. Result(s): There were no significant differences found in clinical and hematologic features between hypertensives and non-hypertensives suffering from COVID-19. Conclusion(s): The present study concludes that there is no evidence that either use of ACE inhibitors is useful or harmful in patients with hypertension. Therefore, it is endorsed to use these agents in the management of hypertensives in patients suffering from COVID-19, till further evidence is found.Copyright © 2023, Dr Yashwant Research Labs Pvt Ltd.

ABSTRACT
Background: Hymenoptera venom immunotherapy (VIT) is a safe and effective treatment for Hymenoptera venom allergy (HVA). Unexpected events, such as venom extracts shortage or COVID-19 pandemic, can impact HVA management, and a change in VIT supplier may became necessary. We aimed to evaluate the safety of switching VIT manufacturer without any dose adjustments. Method(s): A retrospective study of patients treated with VIT between 2013 and 2021, in the maintenance phase and without any previous systemic reactions was performed. All the patients switched to another manufacturer while keeping the same venom without any dose modification. All venom extracts were aqueous preparations. Demographic and clinical data were also analyzed. Result(s): A total of 40 patients were included (31 male, median age 44 years old);76% lived in a rural environment, 58% had apiaries <3km from home or work, and 18% were medicated with beta-blockers and/or angiotensin converting enzyme inhibitors. Most patients (68%) were treated with bee venom and the remaining wasp venom. The median time between the beginning of the maintenance phase and the switch to a different VIT supplier was 18 months [1-52 months]. A total of 42 changes between 4 suppliers were performed without any dose adjustments (39 Roxall to Leti;2 Stallergenes to Roxall;1 Inmunotek -> Roxall), with only local reaction reported. This healthy 50-year- old female patient treated with wasp VIT for 3-months in the maintenance phase, switched from Inmunotek to Roxall and presented a local reaction, similar to previous reactions with the former manufacturer. Two years later, she did not react when VIT was changed from Roxall to Leti. No systemic reactions occurred, and no one discontinued VIT. Conclusion(s): International recommendations regarding changing VIT supplier are scarce. Our results suggest that is safe to switch venom extracts from different manufacturers without the need for dose adjustment in patients on maintenance VIT without any previous systemic reactions.
ABSTRACT
Background: The need for cardiac intensive care unit (ICU) beds remains high in order to monitor and treat emergency patients with severe cardiovascular diseases, particularly during the COVID-19 pandemic. Therefore, timely discharge strategies from the cardiac ICU to peripheral wards are crucial to meet the increasing demand for cardiac ICU beds. Early patient transfer from ICU to the peripheral ward may result in worsening of the patient's clinical condition and outcome with readmission to the ICU, while late transfer may require prolonged expert care and generate unwanted costs. Purpose(s): To investigate whether unplanned readmission of cardiac patients to the cardiac ICU within 72 hours after the index ICU stay is associated with increased mortality risk (primary outcome) and prolonged total hospital length of stay (LOS) (secondary outcome), as well as to identify predictors of ICU readmission in cardiac patients. Method(s): Adult patients who were admitted to the cardiac ICU due to a primary cardiac admission diagnosis at a tertiary care center between 2003 and 2021 were included. Outcomes were analysed with multivariable regression models adjusted for 26 a priori defined variables on patient demographics, underlying comorbidity levels, ICU procedures and administered ICU drugs. Result(s): 30,942 cardiac patients were included, out of whom 1,499 patients (4.84%) were readmitted to the cardiac ICU within 72 hours. 1,023 (68.2%) of readmitted patients were male. Compared to non-readmitted patients, readmitted patients were older, had more underlying comorbidities (Charlson Index), had more severe disease courses (SOFA score, TISS, APACHE II score and SAPS), as well as required more frequently vasopressor therapy, renal replacement therapy and coronary angiographies (Table 1). Readmission to the cardiac ICU was associated with higher in-hospital mortality risk (Odds Ratio 7.52, 95% Confidence Interval (CI) 4.15-12.27, P<0.001) and prolonged hospital LOS (Incidence Rate Ratio 1.56, 95% CI 1.15-1.58, P<0.001). Patients who were readmitted to the ICU had been discharged 18% earlier during the index ICU stay compared to non-readmitted patients (P<0.001). Of note, readmitted and nonreadmitted patients had similar vital parameters at time of ICU discharge after their index ICU stay. During the index ICU stay, non-readmitted patients were prescribed more beta blockers (65.3% vs. 45.8%), ACE inhibitors (37.0% vs. 27.2%) and blood transfusions (10.7% vs. 7.7%). Conclusion(s): Early readmission to the cardiac ICU was associated with increased in-hospital mortality and prolonged hospitalisation. Readmitted patients had been discharged earlier from their index ICU stay and required more comprehensive critical care. ICU discharge strategies should optimally be based on objective patient assessments to facilitate patient safety and shorten hospital length of stay. Artificial intelligence-based algorithms may support clinicians with safe ICU discharge. (Table Presented).
ABSTRACT
Background: The SWEDEHEART quality index of hospitals' adherence to the evidence-based (EB) guidelines for myocardial infarction (MI) patients has been continuously used for several decades in Sweden. The grading protocol is based on the consensus among hospitals. The hospitals are awarded points (0, 0.5, 1) for each of the 11 indicators depending on the proportion of patients who received EB treatment and achieved treatment goals. The 11 indicators at present are reperfusion treatment in STEMI (yes/no), time to-reperfusion treatment in STEMI, time to revascularisation in NSTEMI, P2Y12 antagonists at discharge, ACE-inhibitor/ARB at discharge, the proportion of patients at follow-up, smoking cessation at oneyear, participation in a physical exercise program, target LDL-cholesterol and target blood pressure at one year. Purpose(s): To evaluate whether the SWEDEHEART quality index predicts mortality in patients with MI. Method(s): We used data for all MI patients reported to the SWEDEHEART registry from 72 hospitals in Sweden between 2015-2021. We calculated the difference in quality index between 2021 and 2015. The hospitals were divided into quintiles based on the difference in the score. Logistic regression with log-time offset was used to adjust for confounders (age, gender, diabetes, hypertension, hyperlipidemia, STEMI/NSTEMI, cardiac arrest before admission, occupation status, history of heart failure, prior MI, prior PCI, prior CABG, cardiogenic shock). Result(s): We identified 98,635 patients with MI, 32,608 (33.1%) were women and 34,198 (34.7%) had STEMI. The average age was 70.8+/-12.2 years. The median follow-up time was 2.7 years (IQR 1.06-4.63). The crude all-cause mortality rate was 5.5% at 30-days and 22.3% after longterm follow-up. Most hospitals (72.1%) improved their quality index on average by 3.4% per year (P<0.001). The increase in the quality index continued during COVID-19 pandemic (2020-2021) with average increase of 8.6%, 95% CI, 0.97-1.02;P<0.001. The median change in SWEDEHEART quality index score among the quintiles were -1.5 (Q1), 0,5 (Q2), 2,5 (Q3), 3 (Q4), and 4 (Q5). We found no difference in mortality between the quintiles at 30-days (OR 0.99;95% CI 0.97-1.02;p=1.02) and longterm (OR 1.01;95% CI 0,99-1.02;p=0.850). Conclusion(s): The SWEDEHEART quality index provides valuable descriptive information about hospitals' adherence to the guidelines. However, the index, in its current form, does not predict mortality in patients with MI.
ABSTRACT
Background: Kidney dysfunction is a prevalent disease that leads to many complications over time, such as hypertension, heart disease, and death. ACEI/ARBs are known to be renoprotective. However, few studies describe the association between ACEI/ARB use and kidney dysfunction in patients with SARS-CoV-2 infection. Purpose(s): To explore the association between patients with SARS-CoV- 2 and kidney dysfunction in patients taking an ACEI/ARB. We hypothesize a negative association between patients with SARS-CoV-2 taking an ACEI/ARB and kidney dysfunction. Method(s): A retrospective query between March 2020 and April 2021 was performed in patients 18 years and older who tested positive for SARSCoV- 2 using a polymerase chain reaction test. Patients were divided into two groups: Kidney dysfunction and no kidney dysfunction. Kidney dysfunction was defined as any diagnosis of chronic kidney disease or acute kidney injury. Primary outcomes were all-cause mortality and hospitalization rate. Secondary outcomes included myocardial infarction (MI), hypotension, intubation, vasopressor use, ventricular tachycardia, and ventricular fibrillation. We used multivariate logistic regression to adjust for baseline characteristics. Result(s): We identified 996 patients with kidney dysfunction and 22,106 without kidney dysfunction who tested positive for SARS-CoV-2. The incidence was 258 (25.9%) for ACEI/ARB use in patients with kidney dysfunction. Adjusted odds ratio (OR) for patients with kidney dysfunction was 5.705 (95% Confidence Interval [CI]: 4.554-7.146;p<0.001) for hospitalization, 0.895 (95% CI: 0.707-1.135;p<0.361) for patients taking ACEI/ARB, and 0.529 (95% CI: 0.333-0.838;<0.007) for mortality in patients with kidney dysfunction who took ACEI/ARB. All secondary outcomes had significantly greater adjusted OR (p<0.001), except for MI (p<0.339), ventricular tachycardia (p<0.697), and ventricular fibrillation (p<0.060). Conclusion(s): To date, the benefits of ACEI/ARB in SARS-CoV-2 patients have been controversial. While ACEI/ARB is known to have renoprotective properties, we did not find a significant association between ACEI/ARB and kidney dysfunction in patients with SARS-CoV-2. However, we found the use of ACEI/ARB in patients with kidney dysfunction to be associated with lower mortality. Therefore, clinicians should continue using this medication for its mortality benefits in patients with kidney dysfunction and its cardioprotective effects.
ABSTRACT
Introduction: The respiratory tract infections (RTIs), including pneumonia, influenza and Coronavirus Disease 2019 (COVID-19), are the leading cause of hospitalization and mortality worldwide, contributing to elevated healthcare and societal costs. There is conflicting evidences about the effects of angiotensin converting enzyme inhibitor (ACEIs) or angiotensin II receptor blockers (ARBs) on the susceptibility of RTIs. Method(s): Systematic review of interventional and observational studies that reported use of ACEI or/and ARB on incidence of pneumonia or influenza or COVID-19. Searching was conducted in the databases of PubMed, Excerpta Medica Database (Embase), Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), including the Cochrane Library until April 2022, and references of retrieved relevant articles. We assessed the quality of included studies by using Cochrane Collaboration Risk of Bias tool for Randomized Controlled Trials and Newcastle-Ottawa Scale for observational studies. DerSimonian Laird random-effects meta-analysis was conducted to pool effects for the incidence of pneumonia, influenza and COVID-19. Subgroup analyses were carried according to baseline morbidities (hypertension or cardiovascular diseases, cerebrovascular diseases, chronic kidney disease (CKD) and other non-communicable diseases). Pooled estimates of odds ratios (OR) and corresponding 95% confidence intervals (95% CI) were computed, and heterogeneity among studies was assessed using Cochran's Q test and the I2 metrics, with two tailed P values. Result(s): 73 studies met the inclusion criteria, of which 38 studies assessed the odds of pneumonia, 32 studies assessed Covid-19 and 3 studies assessed influenza. The quality of included studies was moderate. Use of ACEIs was associated with a significantly reduced odds of pneumonia (23 studies: OR 0.74, 95% CI 0.64 to 0.85;I2=76.8%), of COVID-19 (24 studies: OR 0.87, 95% CI 0.82 to 0.92;I2=81.9%) and influenza (3 studies: OR 0.75, 95% CI 0.57 to 0.98, I2=97.7%), compared with control treatment. Use of ARBs was also associated with reduced odds of COVID-19 (25 studies: OR 0.90, 95% CI 0.83 to 0.97;I2=91.9%), but not with odds of pneumonia or influenza. These findings remain consistent in the community population, patients with history of cerebrovascular diseases or cardiovascular diseases, but not in those with CKD, diabetes and chronic obstructive pulmonary diseases. Conclusion(s): The current evidence favours a putative protective role of ACEIs, not ARB in odds of pneumonia, COVID-19 and influenza. Patient populations that may benefit most are those within the community, history of cerebrovascular diseases and cardiovascular diseases. No conflict of interestCopyright © 2023
ABSTRACT
Background: The outbreak of a new coronavirus in China in 2019 (COVID-19) caused a global health crisis. Objective(s): This study was performed to investigate the effect of different underlying diseases on mortality in patients with COVID-19. Method(s): This retrospective cohort study was performed on COVID-19 patients admitted to the Shahid Rahimi and Sohada-ye Ashayer teaching hospitals in Khorramabad, Iran, from 2019 to 2021. Data on disease severity, clinical manifestations, mortality, and underlying disorders were collected and analyzed using the SPSS software version 22 at a 95% confidence interval and 0.05 sig-nificance level. Result(s): The study included 9653 men (48%) and 10332 women (52%). Patients with chronic kidney diseases, cancer, chronic obstruc-tive pulmonary disease, hypertension, cardiovascular disease, and diabetes were at higher mortality risk than those without these underlying diseases, respectively. However, there was no significant relationship between asthma and mortality. Also, age > 50 years, male gender, oxygen saturation < 93 on admission, and symptoms lasting <= 5 days were associated with increased mortality. Conclusion(s): Since patients with underlying diseases are at higher mortality risk, they should precisely follow the advice provided by health authorities and receive a complete COVID-19 vaccination series.Copyright © 2022, Author(s).
ABSTRACT
Background: One of the most common co-morbidities identified among COVID-19 patients was hypertension. Debates on use of Angiotensin-Converting Enzyme Inhibitors (ACEI) and Angiotensin-Receptor blockers (ARB) emerged due to an interaction of the said drugs with Angiotensin-converting enzyme 2 (ACE2), an enzyme which is a point of entry of coronavirus. This study aims to give an update on the work of Zhang et al13 in exploring the association of ACEI/ARB use on mortality and disease severity. Method(s): This meta-analysis involves review of observational studies among hypertensive COVID-19 patients with composite data on ACEI and ARB use. The literature search included studies published from December 2019 until June 30, 2020. Analyses were performed determining the odds ratio of each event using the raw data obtained from each study. Random effects model and Cochran-Mantel-Haenszel Method were utilized at 95% confidence interval. To check for heterogeneity, X2 test and I2 statistic were calculated. Subgroup analyses on ACEI users and ARB users were also done. Cochrane Review Manager (REVMAN 5.3) was used and Forest plots were generated. In this update, the total population of patients with confirmed COVID-19 infection was more than 50,000 with hypertensive patients comprising more than half of the sample population. The analyses done manifested decreased frequency of both outcomes with ACEI/ARB use. Result(s): The calculated odds ratio for mortality and disease severity were 0.63 and 0.56, respectively. However, a statistically significant heterogeneity existed for both outcomes. Subgroup analyses among ACEI users versus ACEI/ARB non-users (odds ratio for mortality = 0.95, I2 = 0%;and odds ratio for disease severity = 0.30, I2 = 0%), and ARB users versus ACEI/ARB non-users (odds ratio for mortality = 0.70, I2 =f 68%;and odds ratio for disease severity = 0.48, I2 = 77%) also manifested decreased frequency of both outcomes. However, significant heterogeneity exists among the ARB users, which is in contrary among the ACEI users. Conclusion(s): The use of ACEI contributes to a statistically significant reduction of mortality and disease severity among hypertensive patients with confirmed COVID-19 infection. We recommend continuing analysis of association of ACEI and ARB use and clinical outcomes since recent analysis suggests a beneficial effect especially in the ACEI group. At present, our findings are still in line with the current recommendation to not discontinue the use of ACEI and ARB among our hypertensive patients.
ABSTRACT
Objective Different hypotheses suggest a contradictory association of statins, angiotensin receptor blockers(ARBs) or angiotensin-converting enzyme(ACE) inhibitors with potential adverse or favorable effects in patients with Coronavirus disease 2019(COVID-19). This study aimed to compare the association of statins, ARB, and ACE inhibitors in COVID-19 and in pneumonia. Design and Method All patients with laboratory-confirmed COVID-19 through April 16, 2020, in Korea were retrieved. We evaluated the association of statins, ARBs, and ACE inhibitors on COVID-19-related mortality within 60 days. Furthermore, a comparison of hazard ratio (HR) was performed between COVID-19 patients and a retrospective cohort of patients hospitalized with pneumonia between January and June 2019 in Korea. Lastly, meta-analysis was performed to compare the results of this study and other reports. Results The median age of the 10,448 COVID-19 patients was 45 years, and statins, ARBs and ACE inhibitors were prescribed in 533 (5.1%), 1,231(11.8%) and 47(0.4%) patients, respectively. As of April 24, 228 patients (2.2%) succumbed to death. After adjusting age, sex, residential area, the history of comorbidities, Cox regression showed significant decrease in HR by 36% associated with statin use (HR 0.635, 95% CI 0.424 - 0.951, p = 0.0274). However, ARBs group showed neutral association (HR 1.034, 95% CI 0.765 - 1.399, p = 0.8270) and ACE inhibitor groups showed insignificant results mainly due to small sample size (HR 0.736, 95% CI 0.314 - 1.726, p = 0.4810). When comparing the HR between COVID-19 patients and a retrospective cohort of patients hospitalized with pneumonia between January and June 2019, the trend of statins and ACE inhibitors showed similar benefit, whereas the protective effect of ARBs observed in the retrospective cohort was lost in the COVID-19 patients. Meta-analysis including the results of this study showed significant benefit of statins and ACE inhibitors, whereas neutral association with ARBs and the mortality. Conclusions Statins were associated with significantly lower mortality of COVID-19, consistent with usual pneumonia patients. While ARBs or ACE inhibitors were not associated with fatal outcome, the possible beneficial effect of ARBs observed in usual pneumonia was attenuated in COVID-19.
ABSTRACT
Background: Coronavirus disease 2019 (COVID-19) caused a major pandemic around world. Considering conflicting information on effect of Angiotensin-converting enzyme 2 (ACE2) and inhibitors of this enzyme on COVID19, we aimed to measure levels of ACE2 in COVID-19 patients and investigate determining factors for their outcome. Method(s): This cross-sectional study was performed on 78 COVID-19 patients that referred to Afzalipour tertiary teaching hospital. Patients enrolled into study after confirmation of the diagnosis of COVID-19 by polymerase chain reaction test. We assess plasma ACE2 levels with an Enzyme-linked immunosorbent assay. The patients followed for if they discharged or deceased. Result(s): 58 out of 78 studied patients discharged (74.4%) and 20 ones (25.6%) deceased. The median length of stay in deceased group was 17.5 days and in discharged ones was 10.0 days (P=0.003). The median levels of ACE2 in discharged and deceased patients was (0.6 ng/mL) and (0.5 ng/mL), respectively which showed no significant difference(P<0.116). The median serum ACE2 levels in 19 patients who received Angiotensin-converting enzyme inhibitors or Angiotensin II receptor blockers were significantly different from those who did not (59 patients) (0.53 ng/mL vs 0.59 ng/mL, respectively) (P=0.041). Conclusion(s): The ACE2 serum level was not related to length of stay and nor to the outcome of COVID-19 patients;however, it was lower in patients received ACE inhibitors or ARBs, which may come with this suggestion that further studies might show the ACE inhibitors or ARBs affection on disease severity or patient's outcome.
ABSTRACT
Aim: COVID-19 infection has affected the whole world. It has been speculated that the virus might hold on to angiotensin-converting enzyme 2 (ACE 2) surfaces of type 2 alveolar cells. ACE inhibitors and angiotensin receptor antagonists (ARBs) are essential antihypertensive and cardiac failure drugs in the guidelines. In this study, we aimed to find the effect of these drugs on clinical, laboratory courses, and outcomes of COVID-19 patients. Material(s) and Method(s): We included 109 patients in this study. There were 43 patients in the ACE/ARB group and 66 patients in the non-ACE/ARB group. The mean age was 60 years in the ACE/ARB group and 52 years old in the non-ACE/ARB group. Basal symptoms, hemogram, CRP, D-dimer, LDH, Ferritin, AST, duration of hospitalization, percentage of intensive care unit (ICU) need, length of stay in ICU were compared between the groups. Result(s): The mean age in the ACE/ARB group was higher than in the other group and was statistically significant (p=.027). The initial symptoms were not different. There were no differences between the laboratory results of the groups. The ICU need was higher in the patients who do not use the drug than in the users (p<.020). Discussion(s): ACE/ARB usage in COVID-19 patients did not worsen the course of the disease. However, ACE/ARB users before COVID-19 pandemic were taken to ICU at a low rate.Copyright © 2022, Derman Medical Publishing. All rights reserved.
