...Jinbo Han; Weiqing Wang; Zhenzhen Zhu; Lei Wang; Yujie Chen; Ruiqi Wang; Kai Guan; Wei Lv Introduction: Eosinophilic chronic rhinosinusitis with nasal polyps (eCRSwNP) exhibits a poorer prognosis than noneCRSwNP. The aim of this study was to analyze the potential of total immunoglobulin E (tIgE...

...Yara Zoabi; Fidan Rahimli Alekberli; Yael Minai-Fleminger; Ron Eliashar; Francesca Levi-Schaffer Introduction: The pathogenesis of chronic rhinosinusitis (CRS) with nasal polyps (CRSwNPs) is not yet completely understood. Based on current knowledge, the infiltration of mast cells and eosinophils...

... with different CLC concentrations. Results: Sixty-eight (62.96%) patients developed recurrence during a 12- to 33-month postoperative follow-up. CLC concentrations in nasal secretions were positively correlated with eosinophil percent in polyp tissue and peripheral blood and were significantly higher in patients...

...Jiayi Yang; Jinjin Fan; Li Fan; Chunyan Yi; Jianxiong Lin; Haiping Mao; Xiao Yang; Xin Wang Introduction: Eosinophilia (eosinophil fraction of leukocytes >5%), an indicative parameter for bioincompatibility in various circumstances, is well established in hemodialysis. However, change...

...Hao Lv; Pei-Qiang Liu; Rong Xiang; Wei Zhang; Shi-Ming Chen; Yong-Gang Kong; Yu Xu Background: A hallmark of eosinophilic chronic rhinosinusitis with nasal polyps (eCRSwNP) is mucosal eosinophil-predominant inflammation. Nasal nitric oxide (nNO) is a known biomarker of eosinophilic inflammation...

...-induced eosinophilic lung disease and eosinophil-associated Th2 immunopotentiation following infection after vaccination. Here, we review the anticipated characteristics of a COVID-19 vaccine to avoid vaccine-associated eosinophil immunopathology. [email protected] 8 06 2020 8...

.... Secondary objectives included the effects of AZD1981 on prostaglandin D 2 (PGD 2 )-induced eosinophil shape change, circulating leukocyte subsets, CRTh2 expression on blood leukocytes, and total blood leukocyte histamine content. Results: Twenty-eight subjects were randomized to AZD1981 or placebo, with 26...

...Mats W. Johansson; Elizabeth A. Kelly; Christopher L. Nguyen; Nizar N. Jarjour; Bruce S. Bochner Background: Siglec-8 is present at a high level on human blood eosinophils and low level on blood basophils. Engagement of Siglec-8 on blood eosinophils causes its internalization and results in death...

.... the rs3806933 CC genotype with asthma in boys (p = 0.032, nonsignificant after multiple testing) and the rs2289276 CC genotype with higher eosinophil numbers in asthmatic girls (p = 0.003). The presence of allergic rhinitis in asthmatic children strengthened the association of the rs11466749 GG genotype...

... that have migrated in response to interleukin-8 (IL-8) may lead eosinophils to accumulate in the airways of patients with asthma and possibly aggravate the disease. In this study, we investigated whether formoterol modified the trans-basement membrane migration (TBM) of eosinophils stimulated...

...-controlled study. We measured hyaluronan and versican levels by enzyme-linked immunosorbent assay in sputum collected before and after the 16-week treatment phase. Patients underwent a predefined prednisone tapering schedule if they remained exacerbation free, and sputum eosinophil percentage, asthma control...

...Young-Sin Song; Eun-Mi Yang; Seung-Hyun Kim; Hyun Jung Jin; Hae-Sim Park Background: Aspirin-exacerbated respiratory disease (AERD) is a clinical syndrome associated with chronic inflammation in the airways coincident with chronic rhinitis, sinusitis, recurrent polyposis and asthma. Eosinophils...

... infiltrating T cells in the tissue. Although the death of certain cells can lead to functional deficiencies, prolonged survival of some effector cells can cause tissue injury and play a role in the pathogenesis of disease [ 12 ]. Eosinophilic granulocytes are directly associated with clinical disease...
