The SWI/SNF complex in eosinophilic and non eosinophilic chronic rhinosinusitis

A prognosis prediction chromatin regulator signature for patients with severe asthma

Severe asthma imposes a physical and economic burden on both patients and society. As chromatin regulators (CRs) influence the progression of multiple diseases through epigenetic mechanisms, we aimed to study the role of CRs in patients with severe asthma. Transcriptome data (GSE143303) from 47 patients with severe asthma and 13 healthy participants was downloaded from the Gene Expression Omnibus database. Enrichment analysis was performed to investigate the functions of differentially expressed CRs between the groups. We identified 80 differentially expressed CRs; they were mainly enriched in histone modification, chromatin organization, and lysine degradation. A protein-protein interaction network was then constructed. The analyzed immune scores were different between sick and healthy individuals. Thus, CRs with a high correlation in the immune analysis, SMARCC1, SETD2, KMT2B, and CHD8, were used to construct a nomogram model. Finally, using online prediction tools, we determined that lanatoside C, cefepime, and methapyrilene may be potentially effective drugs in the treatment of severe asthma. The nomogram constructed using the four CRs, SMARCC1, SETD2, KMT2B, and CHD8, may be a useful tool for predicting the prognosis of patients with severe asthma. This study provided new insights into the role of CRs in severe asthma.

Comparative study of clinical symptoms of chronic rhinosinusitis with nasal polyps patients

AIM

The aim of this study is to explore the clinical characteristics in chronic rhinosinusitis with nasal polyps (CRSwNP) patients with different serum specific IgE (SIgE) and eosinophilic granulocyte infiltration status.

METHODS

This retrospective observational study included patients diagnosed with CRSwNP and underwent functional endoscopic sinus surgery at the Yinchuan First People's Hospital between June 2019 and June 2021. A total of 192 patients with CRSwNP were included (100 males). The patients were 41.7 ± 15.1 years old. The disease course ranged 4.6-18.2 months. The visual analog scale (VAS) score (p < .001), endoscopic score (p = .014), computerized tomography (CT) score (p < .00) and the sino-nasal outcome Test-22 (SNOT-22) score (p < .001) were significantly different among patients with SIgE-positive combined eosinophilic chronic rhinosinusitis (ECRS), patients with SIgE-positive combined non-ECRS, patients with SIgE-negative combined ECRS, and patients with SIgE-negative combined non-ECRS.

RESULTS

In pairwise comparison, the VAS score (20.72 ± 2.24 vs. 13.09 ± 1.62, 13.84 ± 1.34, and 12.67 ± 1.20, respectively), endoscopic score (8.09 ± 1.04 vs. 7.06 ± 0.98, 7.69 ± 1.18, and 7.75 ± 1.07, respectively), CT score (13.18 ± 1.66 vs. 8.79 ± 0.88, 11.08 ± 1.12, and 11.08 ± 1.12, respectively), and SNOT-22 score (27.62 ± 2.31 vs. 12.09 ± 1.83, 14.84 ± 1.84, and 12.97 ± 1.50, respectively) was significantly higher in patients with SIgE-positive combined ECRS compared to patients with SIgE-positive combined non-ECRS, patients with SIgE-positive combined non-ECRS (all p < .0083). The VAS score, endoscopic score, and CT score might be higher in CRSwNP patients with SIgE-positive combined ECRS.

CONCLUSION

In this study, the VAS score, endoscopic score, and CT score were higher in the patients with SIgE-positive combined ECRS. This study might provide a reference for treatment in patients with CRSwNP.

Clinical and laboratory features for various criteria of eosinophilic chronic rhinosinusitis: a systematic review and meta-analysis

Objectives: To evaluate the differences in clinical and laboratory features between eosinophilic chronic rhinosinusitis (ECRS) and non-ECRS and to compare the diagnostic criteria for ECRS.Methods: We compared clinical features and/or laboratory findings classified as ECRS and non-ECRS according to various diagnostic criteria (histological and clinical criteria). In addition, we analyzed studies to compare endoscopic findings, symptom scores, laboratory findings, and computed tomography (CT) findings between ECRS and non-ECRS. Results: Our search included 55 studies with 6,143 patients. As a result of comparing clinical features and/or laboratory criteria with histological criteria, there were no significant differences regarding nasal symptom scores and CT scores according to criteria. Serum eosinophil levels showed differences according to criteria, however, ECRS were higher serum eosinophil levels than non-ECRS in all criteria. In the case of olfactory dysfunction, JESREC and tissue eosinophilia (
