Abstract
BACKGROUND IgE has been known for mediating endothelial cell dysfunction and mast cell (MC) activation to fuel asthma-aggravated high-fat diet-induced atherosclerosis. However, it remains unclear for the mechanism of asthma-mediated atherosclerosis, especially the potential involvement of IgE in the exacerbation of asthma-mediated atherosclerosis with a standard laboratory diet, and the cross talk between endothelial cells and MCs. METHODS Asthma-mediated atherosclerosis mice models under a standard laboratory diet and FcεR1 knock-out mice were used to determine the role of IgE-FcεR1 signaling in asthma-mediated atherosclerosis, which was assessed by Oil Red O staining and immunohistochemistry. Various in vitro assays including nanoparticle tracking analysis and transmission electron microscopy were used to evaluate exosome characteristics. Immunofluorescence and fluorescent in situ hybridization approaches were used to evaluate the effect and mechanism of MC-secreted exosomes encapsulated circular RNA CDR1as (cerebellar degeneration-related 1 antisense) on endothelial cells in vivo and in vitro. Finally, cohort studies examined the plasma CDR1as levels in patients with atherosclerosis with or without allergies. RESULTS Asthma mice with a standard laboratory diet showed increased atherosclerotic lesions and inflammatory infiltration depending on IgE-FcεR1 signal. FcεR1 knockout mice and blockage of IgE-FcεR1 signaling with IgE monoclonal antibody, omalizumab, all significantly alleviated asthma-mediated atherosclerosis and vascular inflammatory remodeling. Anti-inflammation with dexamethasone and stabilization of MC with cromolyn partially alleviated atherosclerotic lesions and mitigated the inflammatory infiltration in arteries. Mechanistically, IgE stimulation upregulates MC CDR1as expression in exosomes and upregulates the endothelial cell adhesive factors VCAM-1 (vascular cell adhesion molecule-1) and ICAM-1 (intercellular adhesion molecule-1) via the CDR1as-FUS (fused in sarcoma)-phos-p65 axis. Knockdown of CDR1as in vivo significantly decreased the endothelial adhesion function and mitigated asthma-mediated atherosclerosis. Furthermore, a cohort study indicated higher plasma CDR1as levels in patients with atherosclerosis with allergies than in patients with atherosclerosis and healthy controls. CONCLUSIONS Exosomes from IgE-stimulated MCs aggravated atherosclerosis through circular RNA CDR1as-mediated endothelial dysfunction, providing a novel insight into asthma-mediated atherosclerosis and potential diagnostic and therapeutic targets.

Abstract
Asthma encompasses of respiratory symptoms that occur intermittently and with varying intensity accompanied by reversible expiratory airflow limitation. In acute exacerbations, it can be life-threatening due to its impact on ventilatory mechanics. Moreover, asthma has significant effects on the cardiovascular system, primarily through heart-lung interaction-based mechanisms. Dynamic hyperinflation and increased work of breathing caused by a sharp drop in pleural pressure, can affect cardiac function and cardiac output through different mechanisms. These mechanisms include an abrupt increase in venous return, elevated right ventricular afterload and interdependence between the left and right ventricle. Additionally, Pulsus paradoxus, which reflects the maximum consequences of this heart lung interaction when intrathoracic pressure swings are exaggerated, may serve as a convenient bedside tool to assess the severity of acute asthma acute exacerbation and its response to therapy.

Abstract
INTRODUCTION Data from studies conducted to date have evaluated clinical atherosclerotic conditions in adult patients with atopic dermatitis (AD). Subclinical atherosclerotic changes that are a precursor of atherosclerotic conditions may begin in childhood. The aim of this study was to investigate the presence of subclinical atherosclerosis in pediatric patients with AD and to determine the associated risk factors. METHODS A total of 59 patients who were referred to our department over a 6-month period and diagnosed with AD, and 53 healthy controls with a similar age and gender were included in the study. Subclinical atherosclerosis markers (carotid intima media thickness [CIMT], distensibility, stiffness, and strain) were measured using conventional echocardiography. The patients' age, SCORAD index, and duration of symptoms were recorded. Serum total immunoglobulin E, C-reactive protein (CRP), blood lipid profile, and complete blood count markers were measured. RESULTS The median age of the patients was 61 (10-103) months, and 59.3% of them were male. The patients with AD had a higher CIMT (1.60 ± 0.35 vs. 1.30 ± 0.50 mm) and a lower distensibility (0.006 ± 0.009 vs. 0.01 ± 0.008) and strain (0.10 ± 0.14 vs. 0.19 ± 0.14) than the healthy controls (p < 0.01 for all), but there was no significant difference with regard to stiffness (10.16 ± 21.75 vs. 8.99 ± 12.66). Significant correlations between CIMT and disease duration, age, and the SCORAD index were found (p < 0.01, p < 0.01, and p < 0.05, respectively). No correlation between the subclinical atherosclerosis markers and the other laboratory results was found (p > 0.05 for all). CONCLUSION This study demonstrates that pediatric patients with AD may express subclinical atherosclerosis markers. The evaluation of subclinical atherosclerosis in these patients revealed that CIMT may be the most important marker, as it displayed positive correlations with symptom duration, age, and disease severity.
