Anemia as a risk factor for disease progression in patients admitted for COVID-19: data from a large, multicenter cohort study.

In respiratory infections, anemia is both a consequence of acute inflammation and a predictor of poor clinical outcomes. There are few studies investigating the role of anemia in COVID-19, suggesting a potential role in predicting disease severity. In this study, we aimed to assess the association between the presence of anemia at admission and incidence of severe disease and death in patients hospitalized for COVID-19. Data from all adult patients admitted for COVID-19 in University Hospital "P. Giaccone" Palermo, and University Hospital of Bari, Italy, were retrospectively collected from 1st of September 2020 to 31 August 2022. The association between anemia (defined as Hb < 13 g/dl and < 12 g/dl in males and females, respectively), in-hospital mortality and severe COVID-19 was tested using a Cox's regression analysis. Severe COVID-19 forms were defined as admission to intensive or sub-intensive care unit or a qSOFAscore ≥ 2 or CURB65scores ≥ 3. p values were calculated using the Student's t test for continuous variables and the Mantel-Haenszel Chi-square test for categorical ones. The association between anemia and the mortality was made using a Cox's regression analysis, adjusted, in two models, for the potential confounders and using a propensity score. Among the 1562 patients included in the analysis, prevalence of anemia was 45.1% (95% CI 43-48%). Patients with anemia were significantly older (p < 0.0001), reported more co-morbidities, and presented higher baseline levels of procalcitonin, CRP, ferritin and IL-6. Overall, the crude incidence of mortality was about four times higher in patients with anemia compared to those without. After adjusting for 17 potential confounders, the presence of anemia significantly increased the risk of death (HR = 2.68; 95% CI: 1.59-4.52) and of risk of severe COVID-19 (OR = 2.31; 95% CI: 1.65-3.24). The propensity score analysis substantially confirmed these analyses. Our study provides evidence that, in patients hospitalized for COVID-19, anemia is both associated with a more pronounced baseline pro-inflammatory profile and higher incidence of in-hospital mortality and severe disease.

Although the clinical course of COVID-19 in its acute phase is now delineated, less known is its late phase characterized by a heterogeneous series of sequelae affecting various organs and systems, including the cardiovascular system, which continue after the acute episode or arise after their resolution. This syndrome, now referred with the new acronym "PASC" (post-acute sequelae of SARS-CoV-2 infection) has been formally recognized by various scientific societies and international organizations that have proposed various definitions. The World Health Organization defines PASC, distinguishing it from "ongoing symptomatic COVID-19", as a condition that arises few weeks after infection, persists at least 8 weeks, and cannot be explained by alternative diagnoses.There are multiple mechanisms responsible for PASC: inflammation, immune activation, viral persistence, activation of latent viruses, endothelial dysfunction, impaired response to exercise, and profound cardiac deconditioning following viral infection. The key symptoms of PASC are palpitations, effort dyspnea, chest pain, exercise intolerance, and postural orthostatic tachycardia syndrome.For PASC treatment, it may be useful to take salt and fluid loading, to reduce symptoms such as tachycardia, palpitations, and/or orthostatic hypotension, or in some subjects the use of drugs such as beta-blockers, non-dihydropyridine calcium channel blockers, ivabradine, and fludrocortisone.Finally, in PASC a gradual resumption of physical activity is recommended, starting with recumbent or semi-recumbent exercise, such as cycling, swimming, or rowing, and then moving on to exercise in an upright position such as running when the ability to stand improves without dyspnea appearance. Exercise duration should also be short initially (5 to 10 min per day), with gradual increases as functional capacity improves.

[2022 Update on myocarditis and pericarditis following COVID-19 vaccination. Expert Opinion of the Italian Society of Cardiology]. / Update 2022 dell'Expert Opinion della Società Italiana di Cardiologia su miocarditi, pericarditi e vaccini contro il COVID-19.

Vaccine-associated myocarditis and pericarditis usually develop within 14 days of COVID-19 vaccination, are exceptionally rare, manifest with mild clinical pictures and are commonly characterized by a favorable evolution. Young men inoculated with two doses of an mRNA vaccine are the subgroup at higher risk. Recent epidemiological studies evaluated the incidence and risk of vaccine-associated myocarditis and pericarditis among men and women, in different ranges of age and specific types of vaccines. Long-term population analyses demonstrated that the cardiovascular risk conferred by COVID-19 extends beyond the acute phase, representing the rationale for implementing prevention strategies for SARS-CoV-2 infection, monitoring specific populations at higher risk and pursuing the completion of the vaccination campaign. This document provides an update on the most recent scientific evidence and critical interpretation of available data in constant evolution towards personalized strategies of immunization.

The current COVID-19 pandemic has renewed interest in providing healthcare services based on the implementation of innovative technologies. Such strategy capillarizes the therapeutic opportunities for larger urban areas, mostly when people are living under extraordinarily difficult circumstances. Improving care delivery in cardiovascular diseases appears particularly feasible when telemedicine is pursued, especially with regard to baseline standard 12-lead electrocardiography, ambulatory electrocardiographic monitoring, and 24-hour ambulatory blood pressure monitoring. Nowadays, these first-line cardiovascular examinations are also available in health centers and pharmacies, and in recent months, there has been an increasing demand of such local services in the absence of specific rules and regulations regarding technical requirements and standards of interpretation that ensure a high quality clinical consultation.The purpose of this position paper is to provide critical requirements for the type/model of devices to be used, training dedicated to healthcare personnel, ensuring security of sensitive data, highlighting type of platforms to be used, as well as for maintaining high reporting quality and standards.

[Myocarditis and pericarditis following mRNA COVID-19 vaccination. Expert opinion of the Italian Society of Cardiology]. / Miocarditi, pericarditi e vaccino a mRNA contro il COVID-19. Expert opinion della Società Italiana di Cardiologia.

The coronavirus disease (COVID-19) pandemic has caused 2.69 million deaths and 122 million infections. Great efforts have been made worldwide to promptly develop effective vaccines and reduce morbidity and mortality rates from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Available vaccines have proven highly effective at preventing symptomatic disease in clinical trials and real-world reports and are playing an essential role in flattening the epidemiology curve and, mostly, in reducing COVID-19 hospitalizations. Some concerns have been raised after very rare cases of myocarditis and pericarditis recently reported by the Centers for Disease Control and Prevention (CDC) as potentially associated with COVID-19 mRNA vaccinations, namely the Pfizer-BioNTech mRNA vaccine (BNT162b2) and the Moderna mRNA vaccine (mRNA-1273). Therefore, the aim of this document is to explore the possible link between COVID-19 mRNA vaccination and the development of myocarditis and/or pericarditis by performing a critical analysis of available data and to provide indications for specific subgroups of individuals.

The Cross-Talk between Thrombosis and Inflammatory Storm in Acute and Long-COVID-19: Therapeutic Targets and Clinical Cases.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) commonly complicates with coagulopathy. A syndrome called Long-COVID-19 is emerging recently in COVID-19 survivors, characterized, in addition to the persistence of symptoms typical of the acute phase, by alterations in inflammatory and coagulation parameters due to endothelial damage. The related disseminated intravascular coagulation (DIC) can be associated with high death rates in COVID-19 patients. It is possible to find a prothrombotic state also in Long-COVID-19. Early administration of anticoagulants in COVID-19 was suggested in order to improve patient outcomes, although exact criteria for their application were not well-established. Low-molecular-weight heparin (LMWH) was commonly adopted for counteracting DIC and venous thromboembolism (VTE), due to its pharmacodynamics and anti-inflammatory properties. However, the efficacy of anticoagulant therapy for COVID-19-associated DIC is still a matter of debate. Thrombin and Factor Xa (FXa) are well-known components of the coagulation cascade. The FXa is known to strongly promote inflammation as the consequence of increased cytokine expression. Endothelial cells and mononuclear leucocytes release cytokines, growth factors, and adhesion molecules due to thrombin activation. On the other hand, cytokines can activate coagulation. The cross-talk between coagulation and inflammation is mediated via protease-activated receptors (PARs). These receptors might become potential targets to be considered for counteracting the clinical expressions of COVID-19. SARS-CoV-2 is effectively able to activate local and circulating coagulation factors, thus inducing the generation of disseminated coagula. LMWH may be considered as the new frontier in the treatment of COVID-19 and Long-COVID-19. Indeed, direct oral anticoagulants (DOACs) may be an alternative option for both early and later treatment of COVID-19 patients due to their ability to inhibit PARs. The aim of this report was to evaluate the role of anticoagulants-and DOACs in particular in COVID-19 and Long-COVID-19 patients. We report the case of a COVID-19 patient who, after administration of enoxaparin developed DIC secondary to virosis and positivity for platelet factor 4 (PF4) and a case of Long-COVID with high residual cardiovascular risk and persistence of blood chemistry of inflammation and procoagulative state.

[Position paper of the Italian Society of Cardiology (SIC) on COVID-19 vaccine priority in patients with cardiovascular diseases]. / Position paper della Società Italiana di Cardiologia (SIC): Priorità del vaccino COVID-19 nei pazienti con patologie cardiovascolari.

In over a year, the COVID-19 pandemic caused 2.69 million deaths and 122 million infections. Social isolation and distancing measures have been the only prevention available for months. Scientific research has done a great deal of work, developing in a few months safe and effective vaccines against COVID-19. In the European Union, nowadays, four vaccines have been authorized for use: Pfizer-BioNTech, Moderna, ChAdOx1 (AstraZeneca/Oxford), Janssen (Johnson & Johnson), and three others are currently under rolling review.Vaccine allocation policy is crucial to optimize the advantage of treatment preferring people with the highest risk of contagion. These days the priority in the vaccination program is of particular importance since it has become clear that the number of vaccines is not sufficient for the entire Italian population in the short term. Cardiovascular diseases are frequently associated with severe COVID-19 infections, leading to the worst prognosis. The elderly population suffering from cardiovascular diseases is, therefore, to be considered a particularly vulnerable population. However, age cannot be considered the only discriminating factor because in the young-adult population suffering from severe forms of heart disease, the prognosis, if affected by COVID-19, is particularly ominous and these patients should have priority access to the vaccination program. The aim of this position paper is to establish a consensus on a priority in the vaccination of COVID-19 among subjects suffering from different cardiovascular diseases.
