Evaluation of the Quality of Life of Patients Suffering from Chronic Rhinosinusitis in a Hospital Setting in Kinshasa

Background and objective: Chronic rhinosinusitis (CRS), a common disease worldwide, has a major impact on patients’ quality of life (QoL). In recent years, the measurement of health-related QoL has made it possible to assess the patient’s state of health, the severity of the CRS and the treatment. The aim of this study was to assess the QoL of patients with CRS in a hospital setting in Kinshasa. Methods: This was a cross-sectional analytical study conducted from June 2020 to May 2021 in the ENT service of the Kinshasa University Hospital and the Monkole Hospital Center. The study involved 113 patients aged at least 18 years, whose QOL was compared with that of a control group consisting of 100 non-patients. QOL was assessed using the Sino-Nasal Outcome Test (SNOT-22) Questionnaire. Results: The mean age of the patients was 41.0 years (18 - 74 years) and that of the controls was 39.1 years (19 - 77 years). More than half of the participants were university graduates. The median SNOT-22 score was 44 (14 - 78) in patients and 7 (1 - 40) in controls. Compared with subjects without CRS, patients with CRS had significantly higher scores in all four domains of the SNOT-22. Around 9 out of 10 patients had a severely impaired QoL compared with 2 out of 10 controls. Considering mildly impaired QoL, we found that in the otological and sleep domains, scores were not significantly different between patients and controls. In the case of severely impaired QoL, however, only the otological domain showed a non-significant difference in scores between the two groups. Conclusion: CRS is a real public health problem in our environment and significantly alters the QoL of patients suffering from it, with repercussions on their professional productivity;hence the need for better management.

Association of Comorbid Asthma and the Efficacy of Bioabsorbable Steroid-eluting Sinus Stents Implanted After Endoscopic Sinus Surgery in Patients with Chronic Rhinosinusitis with Nasal Polyps

Objective To identify factors affecting the efficacy of steroid-eluting sinus stents implanted after endoscopic sinus surgery(ESS)in patients with chronic rhinosinusitis with nasal polyps(CRSwNP).Methods We performed a post-hoc analysis of a randomized self-controlled clinical trial on post-operative implantation of bioabsorbable steroid-eluting stents in patients with CRSwNP.Univariate logistic regression analysis was conducted to identify which of the following factors affect the response to post-operative stent implantation:sex,serum eosinophil levels,history of prior surgery,endoscopic scores,and comorbid conditions(asthma and allergic rhinitis).The primary outcome was the rate of post-operative intervention on day 30,and the secondary outcome was the rate of polypoid tissue formation(grades 2–3)on days 14,30,and 90.Results A total of 151 patients with CRSwNP were included in the post-hoc analysis.Asthma was identified as the only risk factor for a poor response to steroid-eluting sinus stents on post-operative day 30,with an odds ratio of 23.71(95%CI,2.81,200.16;P=0.004)for the need for post-operative intervention and 19(95%CI,2.20,164.16;P=0.003)for moderate-to-severe polypoid tissue formation.In addition,the asthmatic group showed higher rates of post-operative intervention and polypoid tissue formation than the non-asthmatic group on post-operative day 30.Blood eosinophil levels were not identified as a risk factor for poor outcomes after stent implantation.Conclusion Comorbid asthma,but not blood eosinophil level,impairs the efficacy of steroid-eluting sinus stents in the short term after ESS in patients with CRSwNP.

Eosinophilic chronic rhinosinusitis in East Asians

Chronic rhinosinusitis(CRS) is a common disease worldwide, with a prevalence rate of 5%-15% in the general population. CRS is currently classified into two types: CRS with and without nasal polyps. CRS may also be divided into eosinophilic CRS(ECRS) and non-ECRS subtypes based on the presence of tissue eosinophilic infiltration or not. There are significant geographic and ethnic differences in the tissue eosinophilic infiltration, which is predominant in Western white patients and less common in East Asians, despite an increasing tendency for its prevalence in East Asia countries. ECRS differs significantly from non-ECRS in clinical characteristics, treatment outcomes and strategies, and underlying pathogenic mechanisms. ECRS commonly demonstrates more severe symptoms, polyp diseases with a higher incidence of bilateral polyps and sinonasal diseases on computed tomography, and the increase in blood eosinophils. ECRS is considered a special and recalcitrant subtype of CRS, commonly with poor treatment outcomes compared to non-ECRS. The differentiation of specific subtypes and clinical features of CRS will be important for developing novel treatment strategies and improving treatment outcomes for individual phenotypes of CRS. This review discusses clinical features, diagnosis, treatment and prognosis of ECRS in East Asians.

Correlation between Radiological Staging of Chronic Rhinosinusitis and Revision of Endoscopic Sinus Surgery

Introduction: Chronic rhinosinusitis (CRS) is an inflammatory condition affecting the sinonasal mucosa with duration of more than 12 weeks. Multifactorial aetiology contributes to its refractoriness. Functional endoscopic sinus surgery (FESS) is the most common surgical technique preferred in CRS not responding to medical management, showing high success rates. However, some failure has been noted, requiring revision FESS. CT (Computed Tomography) is a diagnostic tool for CRS, and aids in improving surgical outcomes. Combined with the Lund-Mackay scoring system, CT can help stage the CRS, predicting the need for revision surgery. Methods: In our paper, we aimed to study the relationship between severity of CRS using radiological staging and revision of functional endoscopic sinus surgery, assessing outcome after at least 1 year of follow-up. There was a single centre retrospective study involving 150 patients selected by random sampling, to study the correlation between the severity of chronic rhinosinusitis and revision of functional endoscopic sinus surgery (FESS). The study was conducted in the ENT department of King Hamad University Hospital, Bahrain for a time period of 6 months. Records were scanned and scored using Lund-Mackay system. Lund Mackay score of 10 and above was considered severe. The relation between increased severity with Lund Mackay score on the CT scan and the need for revision sinus surgeries was then determined. Results and Conclusion: This study concludes that LMS score in CT scans can be used to predict the outcomes of primary FESS procedure and the need for revision surgery in the management of CRS.

Relationship between chronic rhinosinusitis and lower airway diseases: An extensive review

Signifcant links between allergic rhinitis and asthma have been reported, and the united airway disease hypothesis is supported by numerous findings in epidemiologic, physiologic, pathologic, and immunologic studies. The impact of allergic rhinitis on asthma has been esta-blished. On the other hand, the relationship between chronic rhinosinusitis and lung diseases has been under investigation. Chronic rhinosinusitis is a common disease, and the high prevalence of chronic rhinosinusitis in some kinds of lung diseases has been reported. Recent studies suggest that the treatment of chronic rhinosinusitis has beneficial effects in the management of asthma. Here, we present an overview of the current research on the relationship between chronic rhinosinusitis and lower airway diseases including asthma, chronic obstructive pul-monary disease, cystic fibrosis, diffuse panbronchiolitis, primary ciliary dyskinesia, idiopathic bronchiectasis, and allergic bronchopulmonary aspergillosis.

Quality of Life after Functional Endoscopic Sinus Surgery in Patients with Chronic Rhinosinusitis

Chronic Rhinosinusitis (CRS) is a group of disorders characterized by the inflammation of mucosa of the nasal passages and paranasal sinuses. It includes chronic rhinosinusitis with polyps, CRS without polyps and Allergic Fungal Sinusitis (AFS). This debilitating disease causes negative impact on quality of life (QOL) of patients. Functional endoscopic sinus surgery (FESS) is the mainstay of surgical treatment for patients and improves QOL of patients. This subjective assessment of QOL can be measured by disease specific questionnaires. SNOT-22 questionnaire is widely used and validated questionnaire for this purpose. Prospective study was done on 54 patients. Data were collected using SNOT-22 questionnaire and filled in pre-operative period then in post-operative follow-up visits on 1st, 3rd, 6th and 12th months. Paired sample t-test was used to compare pre-operative and post-operative SNOT scores and multivariate generalized linear model was used to estimate regression parameters for SNOT scores in CRS with polyp and AFS in comparison of CRS without polyps. Out of 54 patients, 59.3% were males, mean age was 35.98, 29.6% were in CRS without polyp group, 44.4% and 25.9% were in CRS with polyps and AFS group. Recurrence occurred in 7.4%, revision surgery required in 3.7% while 22.2% had history of asthma. Paired sample t-test showed statistical significant reduction in post-operative SNOT scores. Linear model results showed SNOT scores in CRS with polyp group was significantly reduced. Thus FESS provides significant improvement in QOL of patients in chronic rhinosinusitis.

Systematic Review and Meta-analysis of Biyuanshu Oral Liquid in the Treatment of Chronic Rhinosinusitis

[Objectives]The objective was to study the clinical efficacy and safety of Biyuanshu oral liquid in the treatment of chronic rhinosinusitis(CRS).[Methods]Randomized controlled trial was adopted to conduct scientific and standardized assessment on the risk of bias in the included papers.With overall effect and incidence of adverse reactions as indices,meta-analysis was performed,and sensitivity and safety analysis was conducted on the included literature.[Results]A total of 15 papers were included,involving 1489 patients.The efficiency of Biyuanshu oral liquid combined with Western medicine was better than that of Western medicine alone.[Conclusions]Biyuanshu oral liquid is safe and effective in treating chronic rhinosinusitis,and is suitable for patients who are not convenient for surgery.However,as the 15 papers included are all low in quality and there is a certain degree of publication bias,the objectivity of the results is affected to some extent.

Dysregulation of E-cadherin in Chronic Rhinosinusitis with Nasal Polyps

E-cadherin is a key epithelial protein and adhesive molecule. This study detected the E-cadherin expression in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and controls, and analyzed its possible role in the pathogenesis of CRSwNP. The expression of E-cadherin was detected by using Western blotting and immunohistochemistry in controls and patients with CRSwNP. Computed tomography (CT) scan findings were scored. The results showed that the E-cadherin expression was up-regulated in patients with CRSwNP as compared with controls (P=0.039) and the positive staining was predominantly localized on the epithelial cell membrane. E-cadherin level was correlated negatively with Lund-Mackay scores in patients with CRSwNP (r=–0.604, P=0.005). It is suggested that E-cadherin may be involved in the pathogenesis of CRSwNP and correlated with disease severity.

CX3CR1 receptor as a potential therapeutic target in chronic rhinosinusitis and allergic rhinitis

Chronic rhinosinusitis and allergic rhinitis are chronic inflammatory diseases that affect the mucous membrane of the nose and paranasal sinuses. These diseases are characterized by recruitment of inflammatory cells to the upper airway. For this to take place a complex interaction between inflammatory cells and the cytokines/chemokines(ligand) liberated at the site of inflammation is involved in a process termed chemotaxis or directed cell migration against concentration gradient of the ligand. This entails signal transduction through the cell surface receptor resulting in cellular functional response and directed migration. In this editorial the novel role of CX3CR1 receptor in the immunopathology of chronic inflammation of the nose and paranasal sinuses will be explored with its potential role as therapeutic target in chronic nasal inflammation.

The Influence of Jia Wei Cang Er San on the Postoperative Bacteriology of Chronic Rhinosinusitis: A Randomized, Placebo-Controlled, Double-Blind Study

Background: Antibiotics have been used routinely for postoperative care in patients with chronic rhinosinusitis (CRS). However, increased bacterial growth was found after antibiotic treatment. In traditional Chinese medicine, Jia Wei Cang Er San has been used to treat CRS. This study was to investigate the influence of Jia Wei Cang Er San on the postoperative bacteriology of CRS. Methods: Ninety-seven CRS patients who underwent functional endoscopic sinus surgery (FESS) were included. They were randomly divided into 3 groups. In the group of Chinese herbal medicine (CHM), patients were given a capsule of Jia Wei Cang Er San tid for 8 weeks and a placebo capsule for amoxicillin q8h for 4 weeks after FESS. In the amoxicillin group, patients were given a capsule of amoxicillin 250 mg q8h for 4 weeks and a placebo capsule for Jia Wei Cang Er San tid for 8 weeks. In the placebo group, patients were given both placebo capsules. Bacterial cultures were performed from bilateral middle meati before FESS, and 8 and 12 weeks after FESS. Results: In the CHM group, bacteria grew in 21 (46%) of 46 specimens pre-operatively, in 23 (50%) specimens 8 weeks and in 17 (37%) specimens 12 weeks after surgery. In the amoxicillin group, bacteria grew in 15 (28%) of 54 specimens pre-operatively, in 30 (56%) specimens 8 weeks and in 32 (59%) specimens 12 weeks after surgery. In the placebo group, bacteria were found in 13 (34%) of 38 specimens pre-operatively, in 16 (42%) specimens 8 weeks and in 12 (32%) specimens 12 weeks after surgery. The rates of bacterial growth did not change by Jia Wei Cang Er San 8 or 12 weeks after surgery, but increased significantly by amoxicillin 8 and 12 weeks after surgery. Conclusion: Our study showed that Jia Wei Cang Er San did not induce bacterial growth after FESS as amoxicillin.

Antibiotic Treatment for Chronic Rhinosinusitis after Endoscopic Surgery: How Long Should Macrolide Antibiotics Be Given?

Background: The purpose of this study was to determine an appropriate period for macrolide antibiotic therapy, and to investigate whether this period could be shorter, for patients with chronicrhino sinusitis (CRS) after functional endoscopic sinus surgery (FESS). Methods: A retrospective analysis of 41 patients undergoing FESS for CRS was performed. All patients underwent pre-operative computed tomography (CT). Patients with fungal sinusitis, allergic fungal sinusitis, and eosinophilic sinusitis were excluded. After FESS, normalized sinus mucosa was confirmed by CT and endoscopy in all patients. Postoperative antibiotic therapy consisted of first-line and second-line regimens. Garenoxacin (GRNX), or clarithromycin (CAM, 400 mg/day) was used as the first-line regimens and low-dose macrolide therapy (CAM, 200 mg/day) was used as the second-line regimen and was prescribed at outpatient visits based on our clinical criteria. Results: Second-line antibiotic therapy (low-dose CAM) was not necessary in 12 of 41 (29%) patients, while it was prescribed in 29 of 41 (71%). The mean duration of low-dose CAM therapy after FESS was 36 days (range 7 to 122 days;median, 25 days). Patients who received second-line therapy (n = 29) were divided into two groups based on the choice of first-line therapy, a GRNX group (n = 13) and a non-GRNX group (n = 16). Those in the non-GRNX had longer periods of postoperative CAM therapy than those in the GRNX group. Conclusion: GRNX was associated with a shorter duration of low-dose macrolide therapy after FESS, and 29% of patients did not need any low-dose macrolide therapy postoperatively. Therefore, macrolide antibiotics should not be routinely prescribed after FESS.

慢性鼻窦炎伴鼻息肉鼻黏膜中纤维蛋白交联和降解相关调控基因表达异常

目的研究慢性鼻窦炎伴鼻息肉(chronic rhinosinusitis with nasal polyps,CRSwNP)患者以及合并哮喘(asthma,AS)患者(CRSwNP+AS)鼻黏膜中纤维蛋白沉积及其相关调控基因的表达情况。方法利用免疫荧光染色评估鼻黏膜中纤维蛋白的沉积情况;利用实时荧光定量聚合酶链式反应检测纤维蛋白交联和降解相关调控基因的表达,以及糖皮质激素治疗后的基因表达变化。结果与对照组相比,CRSwNP鼻黏膜中有显著的纤维蛋白沉积,且呈交联状态,CRSwNP+AS组有更明显的纤维蛋白沉积。基因表达检测显示,促进纤维蛋白交联的基因-凝血因子ⅩⅢA1(factorⅩⅢA chain 1,F13A 1)和抑制纤维蛋白降解的基因-纤溶酶原激活物抑制物1(plasminogen activator inhibitor 1,PAI-1)在CRSwNP和CRSwNP+AS组的表达均升高,并且F13A1在CRSwNP+AS组的表达较CRSwNP显著更高;促进纤维蛋白降解的基因-组织型纤溶酶原激活因子(plasminogen activator tissue type,PLAT)在CRSwNP+AS组的表达显著低于CRSwNP和对照组;尿激酶型纤溶酶原激活因子(plasminogen activator urokinase,PLAU)的表达在两种类型的CRSwNP中均上调。CRSwNP+AS患者经糖皮质激素治疗,可显著下调F13A1、上调PLAT的表达。结论CRSwNP患者鼻黏膜中存在大量纤维蛋白沉积,可能与纤维蛋白交联和降解相关基因的表达失调有关,合并AS患者鼻黏膜中F13A1和PLAT的表达失调更为明显。
