The relationship of chronic rhinosinusitis and depression

Mendelian randomization and single-cell expression analyses identify the causal relationship between depression and chronic rhinosinusitis

Background

The causative relationship between chronic rhinosinusitis (CRS) and depression remains unclear. Herein we employed Mendelian randomization (MR) coupled with single-cell analysis to investigate the causality between CRS and depression.

Methods

Data pertaining to CRS and depression were mined from the genome-wide association study database, and a single-cell dataset was sourced from the literature. To explore causality, we conducted bidirectional MR analysis using MR-Egger, weighted median, inverse variance weighted (IVW), simple mode, and weighted mode, with IVW representing the most important method. Further, sensitivity analysis was performed to evaluate the robustness of MR analysis results. Candidate genes were analyzed via single-cell combined MR analysis.

Results

Forward MR analysis indicated depression as a risk factor for CRS when depression was the exposure factor and CRS was the outcome (OR = 1.425, P < 0.001). Reverse MR analysis revealed the same positive relationship between CRS and depression when CRS was the exposure factor and depression was the outcome (OR = 1.012, P = 0.038). Sensitivity analysis validated the robustness of bidirectional MR analysis results. Ten cell types (endothelial, ciliated, basal, myeloid, mast, apical, plasma, glandular, fibroblast, and T cells) were identified in the single-cell dataset. The network of receptor-ligand pairs showed that in normal samples, cell-cell interactions were present among various cell types, such as epithelial, mast, myeloid, and endothelial cells. In contrast, CRS samples featured only one specific receptor-ligand pair, confined to myeloid cells. TCF4 and MEF2C emerged as potentially crucial for CRS-associated depression development.

Conclusions

Our findings suggest a bidirectional causal relationship between CRS and depression, offering a new perspective on the association between CRS and depression.

The Impact of Gender on Long-Term Quality of Life After Sinus Surgery for Chronic Rhinosinusitis

OBJECTIVE

To identify the impact of gender on the clinical outcomes of endoscopic sinus surgery (ESS) through the comparison of quality of life measures in female and male patients who undergo surgical treatment for chronic rhinosinusitis (CRS).

STUDY DESIGN

Prospective observational cohort study.

METHODS

Patients with CRS completed the 22-item Sino-Nasal Outcome Test (SNOT-22) and EuroQol 5-Dimension Survey (EQ-5D) preoperatively and annually for 5 years following ESS. Health utility values (HUV) were calculated from EQ-5D scores. Comparisons of cohort characteristics were performed with chi-square and t-tests. A multivariable linear mixed effects model evaluated changes in SNOT-22 and HUV over time by gender.

RESULTS

Among the 1268 patients (54% female) enrolled, 789 and 343 completed postoperative surveys at one and 5 years, respectively. Preoperatively, females experienced more severe symptoms: mean SNOT-22 score (51.1 ± 20.9 female vs. 44.7 ± 20.0 male, p < 0.001) and HUV (0.80 ± 0.14 female vs. 0.84 ± 0.11 male, p < 0.001). These gender differences were resolved by year one postoperatively (SNOT-22: p = 0.083; HUV: p = 0.465). Two years after surgery, however, females reported more severe symptoms (SNOT-22: 25.6 ± 20.7 female vs. 21.5 ± 17.4 male, p = 0.005; HUV: 0.88 ± 0.12 female vs. 0.90 ± 0.11 male, p = 0.018), a difference that persisted at year five. These gender-related differences remained after adjusting for age, race, ethnicity, nasal polyps, history of prior ESS, and smoking status (p < 0.001). Within-subject improvement was comparable between genders (SNOT-22: p = 0.869; HUV: p = 0.611).

CONCLUSION

Females with CRS reported more severe symptoms both before and 5 years after surgery compared to their male counterparts. Understanding the mechanism behind these gender-related differences is important for optimizing CRS treatment.

Cost-utility analysis of dupilumab compared with endoscopic sinus surgery in patients with chronic rhinosinusitis with nasal polyps. Evaluation in Colombia, a developing country

INTRODUCTION

Chronic rhinosinusitis with nasal polyps (CRSwNP) compromise's respiratory function, sleep, concentration, work capacity and quality of life, generating high costs for patient and health systems. The aim of the study was to analyze the cost-utility of Dupilumab compared to endoscopic sinus surgery for patients with CRSwNP.

RESEARCH DESIGN AND METHODS

We developed a model-based cost-utility analysis from the perspective of the Colombian health system to compare Dupilumab vs endoscopic nasal surgery in patients with difficult-to-treat CRSwNP. Transition probabilities were extracted from the published literature about CRSwNP and costing was based on local tariffs. We performed probabilistic sensitivity analysis for outcomes, probabilities, and costs (10.000 Monte Carlo simulations).

RESULTS

The cost of dupilumab ($ 142.919) was 7.8 times higher than nasal endoscopic sinus surgery ($ 18.347). In terms of QALYs, surgery generates better results than Dupilumab: 11.78 vs. 9.05 QALYs.

CONCLUSIONS

From the perspective of the health system, endoscopic sinus surgery for the management of CRSwNP is a dominant alternative in all the analyzed scenarios compared to the use of Dupilumab. From a cost-utility point of view, the use of dupilumab should be considered when the patient requires multiple surgeries or when there is a contraindication for surgeries performance.

Prevalence of Depression and Anxiety in Patients With Chronic Rhinosinusitis: A Systematic Review and Meta-analysis

OBJECTIVE

We performed a meta-analysis and estimated the prevalence of depression and anxiety and their related factors among patients with chronic rhinosinusitis (CRS).

DATA SOURCES

PubMed, Embase, Web of Science, Cochrane Library, CINAHL, PsycINFO, and CBM databases.

REVIEW METHODS

A systematic search was performed for relevant studies published before August 17, 2021. A random effects model was used to estimate the prevalence of depression and anxiety. Subgroup analysis was performed by continent or region, study setting, sex, sample size, diagnosis, and assessment method.

RESULTS

Twenty-two articles covering 40,956 patients were included in the meta-analysis. The pooled crude prevalence estimates of depression and anxiety were 25.2% (95% CI, 20.9%-29.6%) and 28.9% (95% CI, 16.1%-41.6%), respectively. Subgroup analyses revealed the following: (1) continent or region, study setting, sex, sample size, depression assessment method, and CRS diagnosis were significantly correlated with the prevalence of depression, and (2) continent or region, study setting, sample size, anxiety assessment method, and CRS diagnosis were significantly correlated with the prevalence of anxiety. Meta-regression analysis revealed that study setting and sample size were negatively associated with the pooled prevalence of depression. In contrast, CRS diagnosis and anxiety assessment method were positively associated with the pooled prevalence of anxiety.

CONCLUSION

Depression and anxiety are common in patients with CRS, especially among clinics. Therefore, in patients with CRS, screening and early diagnosis of depression and anxiety are necessary for prevention and treatment.

Alterations of monoamine neurotransmitters, HPA-axis hormones, and inflammation cytokines in reserpine-induced hyperalgesia and depression comorbidity rat model

BACKGROUND

Pain and depression often occur simultaneously, but the mechanism of this condition is still unclear.

METHODS

The aim of this study was to examine the alterations of monoamine neurotransmitters, hypothalamic-pituitary-adrenal (HPA) axis hormones, and inflammation cytokines in hyperalgesia and depression comorbidities. The reserpine-induced "Sprague Dawley" (SD) rat models were used, and the concentrations of monoamine neurotransmitters serotonin (5-HT), norepinephrine (NE), dopamine (DA), and their metabolic products 5-hydroxyindoleacetic acid (5-HIAA), Homovanillic acid (HVA), 3,4-Dihydroxyphenylacetic acid (DOPAC) in raphe nucleus region were tested by High Performance Liquid Chromatography (HPLC). Serum levels of Adrenocorticotropic Hormone (ACTH), Cortisol (CORT), and inflammatory cytokines interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, interferon (IFN)-γ, IL-4, IL-10 were assessed by enzyme linked immunosorbent assay.

RESULTS

Repeated reserpine injection induced hyperalgesia and depressive behaviors with decreased sucrose preference and horizontal movement distance, and increased immobility time in forced swimming test. The concentrations of 5-HT and NE in raphe nucleus, and ACTH and CORT in serum were elevated in the model group. And the model group showed increases in serum IL-1β and IL-6, and decrease in serum IL-10.

CONCLUSION

More research in these areas is needed to understand the pathogenesis of the disease, so as to find more and better therapeutic targets.

Developments and Emerging Trends in the Global Treatment of Chronic Rhinosinusitis From 2001 to 2020: A Systematic Bibliometric Analysis

Background

Research on the treatment of chronic rhinosinusitis (CRS) has increased in recent decades. We undertook a bibliometric and visualization analysis of studies on CRS treatment to track research trends and highlight current research “hotspots”.

Methods

Original publications related to CRS treatment were obtained from the Science Citation Index-Expanded (SCI-E) and Social Sciences Citation Index (SSCI) databases in the Web of Science Core Collection (WoSCC) of Clarivate Analytics between 2001 and 2020. The country/region, institution, author, journal, references, and keywords involved in this topic were extracted using CiteSpace and VOSviewer to identify and analyze the research focus and trends in this field.

Results

In the previous two decades (especially after 2015), the number of publications on CRS treatment has grown markedly. With regard to publications and access to collaborative networks, the leading country was the USA. High-frequency keywords were “CRS,” “endoscopic sinus surgery,” “sinusitis,” “nasal polyps,” “asthma,” “rhinosinusitis,” “management,” “diagnosis,” “outcomes,” and “quality of life.” Inspection of keyword bursts suggested that “clinical practice guideline,” “adult CRS,” “innate lymphoid cell,” “recurrence,” and “mepolizumab” are the emerging research hotspots. The timeline view of the cluster map revealed that biologic agents have become an up-and-coming “hot topic” in CRS treatment in recent years.

Conclusion

Academic understanding of CRS treatment has improved markedly over the past 20 years. We study analyzed the papers objectively, methodically, and comprehensively, and identified hotspots and prospective trends in the field of CRS treatment. These results will aid rhinologists in gaining greater insight into CRS treatment strategies and identifying the changing dynamics of CRS research.

Short report: nasal obstruction recovery after septoplasty in patients with nasal septal deviation affected by anxiety and depression

This research was aimed to explore whether the recovery of subjective symptoms and objective examination in nasal septum deviation (NSD) patients after septoplasty were related to the degree of preoperative anxiety or depression, in the hope of providing new ideas for clinical treatment. A total of 150 NSD patients were included in this prospective research. Visual analogue scale (VAS) scores, Nasal Obstruction Symptom Evaluation (NOSE) scores, self-rating anxiety scale (SAS) scores, self-rating depression scale (SDS) scores, total inspiratory and expiratory nasal resistance were recorded before and 6 months after operation. The results showed preoperative anxiety or depression was not statistically different between groups in terms of age, gender and course, but positively correlated with nasal obstruction (VAS and NOSE). The recovery of nasal obstruction in patients with anxiety or depression was worse than that in normal NSD patients 6 months after surgery, and was decreased with the increase of anxiety or depression degree. And no significant difference showed in the reduction of total inspiratory and expiratory nasal resistance between groups. In conclusion, anxiety and depression affected the improvement of nasal obstruction feeling in NSD patients after septoplasty, and the improvement was negatively correlated with the degree of anxiety and depression. It is necessary to evaluate the anxiety and depression of NSD patients before septoplasty.

The Potential Role of Bacteriophages in the Treatment of Recalcitrant Chronic Rhinosinusitis

Chronic rhinosinusitis is a common condition affecting 5-12% of the general population worldwide. In a limited number of cases, the disease is recalcitrant to medical and surgical interventions, causing a major impact on physical, social and emotional well-being and increasing pressure on healthcare systems. Biofilm formation and dysbiosis caused by Staphylococcus aureus and Pseudomonas aeruginosa play a role in the pathogenesis of recalcitrant chronic rhinosinusitis. In these cases, a promising treatment alternative is the application of bacteriophages, which are viruses that infect and lyse bacteria. In this review, we appraise the evidence for the use of bacteriophages in the treatment of recalcitrant chronic rhinosinusitis. Additionally, (dis)advantages of bacteriophages and considerations for implementation of phage therapy in otorhinolaryngology practice will be discussed.

Modern approaches to the treatment of chronic polypous rhinosinusitis

Introduction: Today, chronic polypous rhinosinusitis (CPR) occupies a special place among otolaryngological diseases, the incidence rate of which increases every year. To date, the main causes of chronic polypous rhinosinusitis are Staphylococcus aureus and anatomical abnormalities.

Diagnostics: Knowledge of a universal algorithm for the diagnosis of this disease, consisting of the collection of anamnesis, endoscopic examination of the nasal cavity, computed tomography of the paranasal sinuses, anterior active rhinomanometry and bacteriological determination of the microbial spectrum, allows diagnosing chronic polyposis rhinosinusitis in time, and, as a consequence, to prescribe a treatment.

Treatment: This review describes conservative therapies, including antibiotics and glucocorticosteroids. Today, the main task of doctors is to find the most effective method of administration of glucocorticosteroids to achieve the maximum effect. One of these methods is the introduction of the drug with the help of nebulizer, as in this case, the drug will remain in the perirhinal cavity for a long time and have the maximum effect due to the directed action only in the area of the pathological process.

Features of chronic polypous rhinosinusitis in childhood: It should be noted that children under 12 years of age due to the formation of the paranasal sinuses at different stages of ontogenesis will be characterized by different forms of chronic polyposis rhinosinusitis. That is why they should be known and taken into account when making a diagnosis and prescribing a treatment.

Conclusion: Today, the frequency of chronic rhinosinusitis increases exponentially, which makes the question of the modern approach to its treatment the most relevant. It is possible that additional research in this area will solve the issue of searching for both the optimal path of therapy and treatment of CPR in children.
