ABSTRACT
Introduction: Spontaneous pneumothorax is a rare complication of coronavirus disease 2019 (COVID-19), primarily reported in adults. Pediatric cases with bilateral pneumothorax are much less reported. Case Presentation: We presented the case of a five-year-old previously healthy boy who developed persistent fever, abdominal pain, generalized maculopapular rash, and dyspnea before admission. His chest computed tomography (CT) showed a viral involvement pattern of pneumonia suggestive of COVID-19. Subsequently, he was confirmed with multisystem inflammatory syndrome in children (MIS-C). While he responded well to the therapies, on the fifth day of admission, he developed respiratory distress again. A chest roentgenogram showed bilateral spontaneous pneumothorax. Bilateral chest tubes were inserted, and his condition improved sig-nificantly after five days of admission to the intensive care unit. Two weeks later, he was discharged in good condition. Conclusion(s): Children with MIS-C associated with COVID-19 may develop primary spontaneous pneumothorax. Owing to the clinical picture overlapping with MIS-C associated with COVID-19, the timely diagnosis of pneumothorax may be challenging in such patients.Copyright © 2022, Author(s).
ABSTRACT
BACKGROUND: According to the results of the ESSE-RF study, the frequency of obesity in the population reached 29.7%. Obesity is one of the main risk factors for the development of cardiovascular diseases. Features of the course of COVID-19 in patients with obesity is a very urgent problem. AIM: The aim of the study was a comparative investigation of clinical and laboratory-instrumental parameters in AH patients with or without obesity who had COVID-19 associated pneumonia, to identify the role of obesity as a potential predictor of post-COVID cardiovascular complications 3 months after discharge from the hospital. MATERIALS AND METHODS: Materials and methods. The study included 174 patients with COVID-19-associated pneumonia. Group 1 included 78 patients with AH without obesity, group 2 - 96 patients with AH and obesity. All patients were tested with a blood sample at the time of admission and 3 months after discharge from the hospital. We assessed parameters of general blood test, biochemistry, hemostasis, inflammation biomarkers - concentration of C-reactive protein (CRP), highly sensitive CRP (hs-CRP), homocysteine, IL-6, etc. All patients initially underwent computed tomography of the chest. In both groups, 24-hour blood pressure monitoring was performed using BPLaB device, according to the standard protocol;echocardiography using an expert class ultrasound diagnostic system Vivid S70. The study is registered with the Clinical Trials.gov database Identifier: NCT04501822. RESULT(S): Results. The biomarker that significantly distinguished the both groups of patients, as well as subgroups according to the degree of obesity was the concentration of maxCRP and hs-CRP, which was significantly higher in group 2. In addition, the registered maximum values of MPO, NT-proBNP, IL-1,6, TNA-alpha and NRL parameters in group 2 of patients with 2-3 degrees of obesity, may indicate the highest probability of developing delayed adverse cardiovascular complications in this group of patients. Mean systolic blood pressure, variability of systolic and diastolic blood pressure, and heart rate at night were significantly higher in AH patients with obesity. Numerous correlations of obesity with laboratory and instrumental parameters have been registered, which may indicate an increased likelihood of delayed unwanted cardiovascular complications in this particular group of patients. Multiple regression showed that obesity is an independent predictor of an increase in LDH, hs-CRP and right atrium. CONCLUSION(S): Dynamic control of the studied parameters in patients with AH and OB registered an increased concentration of CRP at the initial stage and 3 months after treatment, with a general trend towards a decrease in the increased initial structural parameters of ECHO CG. The logistic regression method showed that the presence of OB in patients with AH is an independent factor causing increased levels of immune inflammation (CRP), a marker of tissue destruction (LDH), and load on the right atrium.Copyright © Endocrinology Research Centre, 2022.
ABSTRACT
Aim. To determine the prevalence and show the features of the development of newly diagnosed heart failure (HF) in patients with dyspnea after a coronavirus disease 2019 (COVID-19). Material and methods. This clinical prospective observational study was conducted during 2020-2022. The study consecutively included 368 outpatients with shortness of breath, who applied to the clinic. Depending on the presence of prior COVID-19, the patients were divided into 2 groups: the first group consisted of 205 patients with shortness of breath after COVID-19, the second group - 163 patients without prior COVID-19. All patients underwent a clinical examination within 3 days after presentation with an assessment of outpatient records and other medical documents for the differential diagnosis of dyspnea. The severity of dyspnea was determined using the Modified Medical Research Council Dyspnoea Scale (mMRC). The diagnosis of HF was verified in accordance with the 2020 Russian Society of Cardiology guidelines and in some cases reclassified in accordance with the 2021European Society of Cardiology guidelines. For further analysis, 2 subgroups of patients with HF were identified depending on the presence and absence of prior COVID-19. The subgroup analysis excluded patients with acute heart failure, acute illness, and conditions requiring hospitalization and/or intensive care. Results. Among 368 patients who presented to the clinic with dyspnea during 2020-2022, 205 patients (55,7%) had COVID-19. The average period of treatment after COVID-19 was 3,5 [1,5;22,4] months. Patients after COVID-19 applied earlier after the onset of dyspnea, which is associated with higher mMRC score. The prevalence of HF among patients with shortness of breath after COVID-19 was significantly higher than in patients without this pathology in history, and amounted to 19,0% vs 9,8% (p=0,021). Prior COVID-19 increased the relative risk (RR) of HF in patients with shortness of breath by 1,7 times. RR for HF in systolic blood pressure >140 mm Hg increased by 1,9 times, while in diastolic blood pressure >90 mm Hg - by 1,9 times, with the development of a hypertensive crisis - by 28%, with a heart rate >80 bpm at rest - by 1,4 times, with the development of type 2 diabetes - by 31%, in the presence of pulmonary fibrosis - by 2,3 times. Patients with shortness of breath after COVID-19 had more severe HF, both according to clinical tests and according to the blood concentration of N-terminal pro-brain natriuretic peptide (NT-proBNP), mainly with the preserved ejection fraction (EF) with a higher prevalence of left atrial (LA) enlargement in combination with a decrease in right ventricular (RV) systolic function and its dilatation. In patients after COVID-19 in the presence of chronic kidney disease, the RR for HF increased by 4,5 times;in the presence of C-reactive protein >4 mg/l - by 1,6 times. Conclusion. Every fifth patient with shortness of breath 3,5 months after COVID-19 had more severe HF, both according to clinical tests and according to blood NT-proBNP concentration, mainly with preserved EF with a higher prevalence of LA increase in combination with a decrease in RV systolic function and its dilatation. The risk of HF is interrelated with the female sex and multiple comorbidities.Copyright © 2023, Silicea-Poligraf. All rights reserved.
ABSTRACT
BackgroundA black female in her 40s presented with a nonpruritic rash for 10 months consisting of bumps on the face, hands, forearms, and thighs. She had no prior treatment. Past medical history was significant for pulmonary embolism (PE) 6 years prior. She had no personal or family history of autoimmune disease. Physical exam revealed numerous smooth 2-3 mm skin-colored papules over the bilateral forearm dorsa, hands, anterior thighs, and face. Serum protein electrophoresis revealed monoclonal IgG lambda gammopathy. Skin biopsy of her left elbow showed dermal fibroplasia with mucin deposition. IgG was less than 1.5 grams/deciliter;bloodwork was otherwise stable. The diagnosis of scleromyxedema was rendered.ObjectivesThe objective of this clinical case was to evaluate a neurologic sequela of COVID-19 infection in a patient with scleromyxedema.MethodsOne month following diagnosis of scleromyxedema, our patient was diagnosed with COVID-19 five days before admission to the emergency department with altered mental status and aphasia. Rheumatology was consulted due to malignant hypertension and acute kidney injury with question of scleroderma-like renal crisis in the setting of recently diagnosed COVID-19 infection, although she had no other features of systemic sclerosis. The infectious disease team was consulted due to COVID-19-induced inflammatory reaction.ResultsThe patient's creatinine kinase and brain natriuretic peptide were elevated. Creatinine and potassium trended upwards. She developed seizures and became hemodynamically unstable with rapidly declining clinical status. She was transferred to the intensive care unit, where she developed respiratory arrest, shock, hyperkalemia, and acidemia. She received escalating doses of pressors but experienced frequent arrhythmic disturbances and developed asystole. Resuscitation efforts were unsuccessful;she expired within 24 hours of consultation.ConclusionDermato-neuro syndrome (DNS) is a potential complication of scleromyxedema associated with confusion, dysarthria, seizures, and coma. The patient's clinical presentation is consistent with DNS in the setting of scleromyxedema likely precipitated by COVID-19. Intravenous immunoglobulins are first-line treatment for scleromyxedema;however, it is associated with risk of venous thromboembolism. The patient was considered for treatment as an outpatient but deferred due to history of PE. She was reevaluated for treatment upon presentation to the hospital, but given the severity and rapidity of her condition, it was already too late. This is the second reported case of COVID-19 induced DNS in a patient with scleromyxedema. Given the severity, we recommend early initiation of treatment in patients with scleromyxedema and aggressive treatment for those contracting COVID-19.References[1] Haber R, Bachour J, El Gemayel M.

ABSTRACT
Background: At our hospital, people with COVID-19 (coronavirus disease 2019) had a high rate of pulmonary barotrauma. Therefore, the current study looked at barotrauma in COVID-19 patients getting invasive and non-invasive positive pressure ventilation to assess its prevalence, clinical results, and features. Methodology: Our retrospective cohort study comprised of adult COVID-19 pneumonia patients who visited our tertiary care hospital between April 2020 and September 2021 and developed barotrauma. Result(s): Sixty-eight patients were included in this study. Subcutaneous emphysema was the most frequent type of barotrauma, reported at 67.6%;pneumomediastinum, reported at 61.8%;pneumothorax, reported at 47.1%. The most frequent device associated with barotrauma was CPAP (51.5%). Among the 68 patients, 27.9% were discharged without supplemental oxygen, while 4.4% were discharged on oxygen. 76.5% of the patients expired because of COVID pneumonia and its complications. In addition, 38.2% of the patients required invasive mechanical breathing, and 77.9% of the patients were admitted to the ICU. Conclusion(s): Barotrauma in COVID-19 can pose a serious risk factor leading to mortality. Also, using CPAP was linked to a higher risk of barotrauma.Copyright © 2021 Muslim OT et al.
ABSTRACT
Blood pressure is controlled through a complex network of interacting peptide systems, principally involving the angiotensin, natriuretic peptide, endothelin and apelin families. The most complex and thoroughly investigated is the renin-angiotensin system (RAS) in which selective and potent inhibitors of the key biosynthetic proteolytic enzymes, renin and angiotensin-converting enzyme (ACE), have proved to be valuable drugs for the effective treatment of hypertension and heart failure, as well as other cardiovascular and renal disorders. Some of the other proteases in these pathways, e.g.neprilysin and ACE2, are also being explored as potential drug targets. © 2023 Elsevier Inc. All rights reserved.

ABSTRACT
OBJECTIVES: The type of arrhythmias, and their prevalence in mild/moderate and severe COVID-19 patients admitted to the hospital are unknown from a prospective cohort study. METHODS: We did continuous electrocardiograms along with multiple ECGs in 305 consecutive hospitalized COVID-19 patients. RESULTS: The incidence of arrhythmias was 6.8% (21/305) in the target population. The incidence of arrhythmias was 9.2% (17/185) in patients with severe COVID-19 illness and 3.3% (4/120) in patients with mild/moderate COVID-19 illness with no significant difference (p = 0.063). All the arrhythmias were new-onset arrhythmias in this study. 95% (20/21) of these arrhythmias were atrial arrhythmia with 71.42% (15/21) being atrial fibrillation and one episode of sustained polymorphic ventricular tachycardia. No episode of high-grade atrioventricular block, sustained monomorphic ventricular arrhythmia, or torsades de pointes arrhythmias were observed in this study. The patients with arrhythmias were admitted to the intensive care unit (80.9% vs. 50.7%; p: 0.007), were on a ventilator (47.6% vs. 21.4%; p: 0.006), and had high in-hospital mortality (57.1% vs. 21.1%; p: 0.0001) than patients without arrhythmias. CONCLUSION: Atrial arrhythmias were the most frequent arrhythmias in hospital-admitted COVID-19 patients with atrial fibrillation being the most common arrhythmia.

As the world progressively recovers from the acute stages of the coronavirus disease 2019 (COVID-19) pandemic, we may be facing new challenges regarding the long-term consequences of COVID-19. Accumulating evidence suggests that pulmonary vascular thickening may be specifically associated with COVID-19, implying a potential tropism of severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) virus for the pulmonary vasculature. Genetic alterations that may influence the severity of COVID-19 are similar to genetic drivers of pulmonary arterial hypertension. The pathobiology of the COVID-19-induced pulmonary vasculopathy shares many features (such as medial hypertrophy and smooth muscle cell proliferation) with that of pulmonary arterial hypertension. In addition, the presence of microthrombi in the lung vessels of individuals with COVID-19 during the acute phase, may predispose these subjects to the development of chronic thromboembolic pulmonary hypertension. These similarities raise the intriguing question of whether pulmonary hypertension (PH) may be a long-term sequela of SARS-COV-2 infection. Accumulating evidence indeed support the notion that SARS-COV-2 infection is indeed a risk factor for persistent pulmonary vascular defects and subsequent PH development, and this could become a major public health issue in the future given the large number of individuals infected by SARS-COV-2 worldwide. Long-term studies assessing the risk of developing chronic pulmonary vascular lesions following COVID-19 infection is of great interest for both basic and clinical research and may inform on the best long-term management of survivors.
ABSTRACT
Case Presentation: Term male infant born to SARS-CoV-2 positive mother with infant testing negative. ECG for perinatal bradycardia revealed ventricular pre-excitation. Echocardiogram showed asymmetric LV hypertrophy with prominent trabeculations, subaortic narrowing with no pressure gradient, and normal biventricular systolic function. Rapid increase in RV pressure estimates and NT-proBNP in first week if life concerning for diastolic dysfunction. Anti-arrhythmic therapy initiated for SVT with subsequent resolution. Later, developed progressive LV dilation and systolic dysfunction. Myocardium showed regions resembling non-compaction and others concerning for infiltrative process. Cardiac MRI showed no obvious tumors, but rhabdomyomas could not be ruled out given similar appearance to myocardium. Due to worsening heart failure, everolimus therapy initiated to target potential rhabdomyomas while awaiting genetic testing for tuberous sclerosis. Subaortic narrowing and LV hypertrophy improved within days, and LV appearance became more consistent with non-compaction. Genetic testing revealed a TSC2 gene variant consistent with tuberous sclerosis. Systolic function improved, and patient discharged on afterload reduction. Echocardiogram 6 months post-discharge shows continued LV dilation and mild systolic dysfunction. Discussion(s): Although outflow obstruction and arrhythmias are common with cardiac rhabdomyomas and can cause dysfunction, our patient developed progressive dysfunction in the absence of outflow tract gradient or prolonged arrhythmia. As rhabdomyomas subsided, it became clearer that he had an underlying cardiomyopathy. We suspect that rhabdomyomas in the setting of abnormal myocardium led to abnormalities in myocardial contractility and compliance causing combined systolic and diastolic dysfunction. After complete resolution of rhabdomyomas, cardiac function has improved. However, he continues to have ventricular dilation and mild dysfunction attributable to cardiomyopathy. It is unlikely that mother's SARS-CoV-2 infection played a role as infant tested negative and clinical picture was not consistent with myocarditis.

ABSTRACT
Introduction: Catestatin (CST) is a peptid with imunomodulatory, antiinflammatory, and antimicrobial activities. Acute coronavirus disease 2019 (COVID-19) caused by the SARS-CoV-2 virus can cause a systemic disease range unpredictably from mild flu-like disease to multiple organ failure. Despite many studies and scientific interest for COVID 19, there is lack of information regarding correlation between serum CST levels and clinical course od COVID 19. There are only few studies investigated CST plasma levels at COVID 19 patients, but mostly at ICU-patients, and those studies revealed that COVID 19 patients release significant amounts of CST in the plasma and CST predicts a poor COVID-19 outcome. In our work the aim was to demonstrate plasma CST levels and correlation with clinical outcome in a group of severe COVID 19 patients admitted in non-ICU department. Method(s): The subjects were patients admitted during second surge of COVID 19 in April and May 2020 in non-ICU unit for COVID 19 patients (high dependency unit) in Infectology department of University Hospital Split, Croatia. The reason of admission was pulmonary infiltrates and COVID 19 positivity confirmed with nucleic acid test. In study were included 32 subjects (25 females, 7 males) (Table 1). An enzyme-linked immunosorbent assay was used for serum CST levels assessment. Result(s): We found significant positive correlation between serum CST levels and: C-reactive protein (r = 0.423, p = 0.008), D-dimers (r = 0.395, p = 0.013), hsTNT (high sensitivity troponin T) (r = 0.603, p < 0.001), proBNP (N-terminal-pro brain natriuretic peptide) (r = 0.569, p < 0.001), and hospitalisation days (r = 0.388, p = 0.014). There was significant difference between groups of participants with SOFA < 3 (n = 18) and SOFA > 3 (n = 14) in catestatin serum levels (7.25 +/- 3.66 vs. 11.05 +/- 9.52 ng/ml;p = 0.065). Conclusion(s): This study confirmed that serum CST levels could have important role as clinical prognostic parameter among non-ICU COVID 19 patients.
ABSTRACT
Case Presentation: A 23-year-old previously healthy man presented with progressive dyspnea. Physical examination revealed jugular venous distension and lower extremity edema. Laboratory testing demonstrated elevated B-type natriuretic peptide (193 pg/mL) and normal high sensitivity troponin. Echocardiogram revealed small pericardial effusion, respiratory variation in diastolic flow across the mitral valve, diastolic septal bounce, and annulus reversus (Figure). The differential diagnosis for constrictive pericarditis was broadly considered in the context of a recent febrile illness and frequent travel to Hawaii and Vietnam;we included infectious, autoimmune, and malignant etiologies. Cardiac magnetic resonance imaging revealed thickening and diffuse enhancement in the pericardium as well as ventricular interdependence. Chest CT identified hilar and anterior mediastinal lymphadenopathy. Laboratory testing was positive for QuantiFERON gold and negative for COVID-19, HIV, and ANA. Transbronchial biopsy demonstrated non-necrotizing granulomas with negative acid-fast bacilli smear, culture, and polymerase chain reaction for mycobacterial DNA. Reexamination identified a red-brown plaque on the patient's thigh;biopsy showed granulomatous inflammation and rod-shaped organism with positive FITE staining. A presumed unifying diagnosis was made of extrapulmonary tuberculosis (TB) complicated by constrictive pericarditis. Discussion(s): Despite being a primarily pulmonary disease, systemic involvement can occur with TB with the heart being one of the most common extrapulmonary sites. This case highlights 1) the utility of extra-cardiac diagnostic testing (e.g., dermatologic biopsy) in the diagnosis of constrictive pericarditis, and 2) the diagnostic challenge associated with extrapulmonary TB, particularly paucibacillary disease that requires a detailed social history with "out-of-the-box" thinking.
ABSTRACT
Introduction: COVID-19 has been responsible for millions of deaths and intensive care unit (ICU) admissions all over the world. Identifying the patients at risk of developing a severe form is crucial for an optimized orientation and allocation of resources. The main objective of our study was to identify among a selection of biomarkers, those predictive of short term worsening in COVID-19. Method(s): This is an ancillary study using clinical data and collected biobanking from the multicentric cohort study COVIDeF, which included prospectively from March 31th 2020 to March 30th 2021, patients admitted with a suspected Sars-CoV2 infection in the Assistance- Publique-Hopitaux de Paris network, France. Patients with confirmed COVID-19 were divided in 2 groups: a severe (ICU admission or invasive or non-invasive ventilation or ARDS or death) and a control group (no worsening). The routine blood tests and following biomarkers: troponin, C Reactive Protein (CRP), procalcitonin, Mild- Regional pro-Adrenomedulin (MR-proADM), pro-endothelin, SuPAR, NT-proBNP, calprotectin, PF4, D-dimers, were measured in plasma or serum and compared between both groups using a conditional logistic regression. Result(s): Among the 1040 first patients included in the COVIDEF cohort, we selected 512 patients having a blood sample drawn at admission before worsening, of which 60 secondarily worsened (severe group). The mean age was 59.5 (+/- 19.5) years and 50.2% were females. Among the biomarkers tested, three were independently associated with worsening: CRP (mg/l) OR 1.01 [IC 1.01-1.02], procalcitonin (ng/ml) OR 0.4428 [0.21-0.95] and MR-proADM (pg/ml) OR 3.012 [1.06-8.53]. Conclusion(s): Among a selection of biomarkers of interest, MRproADM appears to best identify at admission COVID-19 patients at risk of worsening. Future interventional studies should test the efficacy and security of this biomarker to rule-in and rule-out severe outcome and the usefulness for allocating resources.

ABSTRACT
Introduction: Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) exhibits 25-30% mortality in hospitalized patients with heart failure (HF). Cardiovascular disease is the most significant comorbidity associated with increased mortality in COVID-19 patients with data suggesting local and systemic inflammation play a critical role in cardiac functional abnormalities. SARS-CoV-2 vaccination reportedly reduces severity of infection. We sought to characterize if vaccination had any protective effect on patients with HF hospitalized for acute COVID-19. Hypothesis: Baseline cardiac biomarkers including CRP, ferritin, high sensitivity cardiac troponin I (hs-cTnI), and pro-brain natriuretic peptide (pBNP) may be lower in vaccinated COVID-19 HF patients revealing the impact of vaccination on reducing inflammation by SARS-CoV-2 infection. Method(s): Electronic health records underwent IRB exempted extraction of demographics, anthropometrics, vital signs, laboratory tests, and ICD-10-CM-based Elixhauser comorbidity categories. Continuous data summarized with median [IQR] were compared using Kruskal-Wallis test and discrete data with chi-squared test. Result(s): Among HF patients with a recorded vaccine status admitted between July 3, 2021 and March 17, 2022, 206 underwent acute COVID-19 hospitalization. Vaccinated (n=91, 44%) and unvaccinated (115, 56%) patients exhibited statistically similar distribution of males (56%), aged 78[69-86] years with comorbidities 5[4-7] distributed across Whites (88%), Blacks (8%), and other races (4%). There were no intergroup differences with most prevalent comorbidities at admission including hypertension (99%), diabetes (41%), chronic pulmonary disease (37%), obesity (36%), deficiency anemia (31%), and renal failure (25%). There were no intergroup differences in initiation of COVID-19 directed treatments. Baseline biomarkers in vaccinated versus unvaccinated were CRP 6.0[1.3-9.5] vs. 6.9[2.7-11.3] mg/dL (p=.25), ferritin 171[76-552] vs. 432[79-876] ng/mL (p=.13), LDH 245[192-317] vs. 338[260-439] U/L (p=.003), D-dimer 0.89[0.53-1.73] vs. 1.36[0.95-2.80] mg/L FEU (p=.06), hs-cTnI 27[14-67] vs. 28[16-81] ng/L (p=.39), and pro-BNP 3487[1516-7162] vs. 3278[1549 vs. 9001] pg/mL (p=.90). Clinical visit criteria respectively were hospital LOS 4.9[2.9-10.3] vs. 5.4[3.4-10.3] days (p=.27), ICU admission 10% vs. 17% (p=.15), and discharge disposition expired or Hospice 15% vs. 16% (p=.48). Rehospitalization occurred similarly between groups and was not significant. Conclusion(s): Acute and chronic inflammation are pathogenic drivers of HF. Inflammatory biomarkers lower among vaccinated patients with HF included CRP, ferritin, D-dimer, and hs-cTnI, although not significant. LDH, however, was significantly lower suggesting improved host widespread tissue perfusion as one mechanism of reduced severity in patients with HF undergoing SARS-CoV-2 vaccine breakthrough infection. One study caveat is that despite inclusion of all patients, these preliminary findings are likely not sufficiently powered to validate our hypothesis.Copyright © 2022
ABSTRACT
Background: Although Brain Natriuretic Peptide (BNP) provides strong prognostic information of an unfavorable outcome in patients with acute heart failure (AHF), there is little information of its relevance as a biomarker for outcomes in COVID-19 and its complications Purpose: To evaluate the association of increased BNP levels with complications and in-hospital mortality in a cohort of hospitalized COVID-19 patients. Method(s): The study included COVID-19 patients with data on BNP levels included in the ISACS COVID-19 registry. The population was categorized according to the presence of peak BNP levels >=100 pg/mL during hospitalization. Primary outcomes included in-hospital mortality, AHF or acute respiratory failure (ARF, defined as PiO2/FiO2<300 mmHg or need for mechanical ventilation). Calculations were conducted using age and sex-adjusted multivariable logistic regression analyses. Results were also stratified according to presence or absence of cardiovascular disease (CVD) history. Differences between subgroups were verified for statistical significance using test for interaction. Result(s): Of the 1152 patients included in the study, 615 (53.4%) had elevated BNP levels. These subjects were older (69.9+/-13.8 vs 59.1+/-16.8, p-value<0.001), had higher rates of cardiovascular risk factors (82.9% vs 57.7%, p-value<0.001) and presented more frequently with a prior history of CVD (either ischemic heart disease, cerebrovascular disease, venous thromboembolism, atrial fibrillation or a history of revascularization) (50.1% vs 27.5%, p-value<0.001). No sex differences were observed. When considering outcomes, BNP levels >=100 pg/mL were associated with increased rates of in-hospital mortality (32.9% vs 4.9%, p-value<0.001), even after adjustment for demographic characteristics (OR: 7.35;95% CI: 4.75-11.40;p-value<0.001). High BNP levels were also strongly associated with an increased risk of AHF (OR 19.9;95% CI 8.6-45.9;pvalue< 0.001), a correlation that persisted both in patients with and without a prior CVD history (p for interaction=0.29). Of note, patients with elevated BNP also had a higher likelihood of developing ARF (OR 2.7;95% CI 2.1- 3.6;p-value<0.001), even in absence of AHF (OR 3.00;95% CI 2.20-4.1;p-value<0.001). Conclusion(s): In COVID-19, blood BNP level not only appears to be predictor of in-hospital mortality and AHF but was also independently associated with an increased risk of ARF. This finding supports the routine use of BNP in all patients admitted to hospital for COVID-19, regardless of a prior history of CVD.
ABSTRACT
The prohormone N-terminal pro-B-type natriuretic peptide (NT-proBNP) is released from stretched cardiac myocytes and is a diagnostic biomarker for heart failure and cardiac dysfunction as well as pulmonary embolism and pneumonia that are frequent complications to severe Coronavirus Disease 2019 (COVID-19). NT-proBNP is frequently elevated in COVID-19. In a recent publication, it was demonstrated that NT-proBNP was strongly associated with mortality in patients with COVID-19, and further investigation of its usefulness as a prognostic tool to predict disease outcomes in COVID-19 was suggested (1). In the recently completed phase 2 trial (angiotensin II type 2 receptor agonist COVID-19 trial [ATTRACT];NCT04452435) in subjects hospitalised with COVID-19, it was investigated whether treatment with the AT2R agonist C21 for 7 days affected the release of the plasma biomarker NTproBNP. ATTRACT was a randomised, double-blind, placebo-controlled, phase 2 trial that investigated the safety and efficacy of C21 treatment (100 mg twice daily) for 7 days in hospitalised subjects with COVID-19, not requiring mechanical ventilation. The results of the trial demonstrated that treatment with C21 on top of standard of care (vast majority of patients received glucocorticoids) significantly reduced the proportion of subjects requiring supplemental oxygen at Day 14, indicating faster recovery with C21 treatment compared to placebo. Blood samples for exploratory analysis were taken before and after 7 days of treatment with C21 or placebo. Plasma NT-proBNP was markedly elevated in both treatment groups before treatment, with average values of 357 and 438 pg/mL in the placebo and C21 groups, respectively, as compared to normal levels of approximately <100 pg/mL. After 7 days of treatment, the C21 group experienced a dramatic reduction in plasma NT-proBNP (by 259 pg/mL) as compared to the placebo group (63 pg/mL) (p=0.02). The results show that short-term C21 treatment decreased the release of NT-proBNP in subjects hospitalised with COVID-19. Further investigations are needed to elucidate whether this is related to effects on COVID-19- induced pulmonary damage or direct protective effects on the heart. We are currently conducting a global phase 3 trial (VP-C21-008) further investigating the effect of C21 in subjects hospitalised with COVID-19 including determination of NT-proBNP.
