Dupilumab improves sense of smell and clinical outcomes in patients with severe chronic rhinosinusitis with nasal polyps with anosmia

Objective Loss of sense of smell is a cardinal symptom of chronic rhinosinusitis with nasal polyps (CRSwNP) and significantly impacts health-related quality of life. Dupilumab significantly improved smell outcomes (loss of smell [LoS] score; University of Pennsylvania Smell Identification Test [UPSIT]) versus placebo in the phase 3 SINUS-24/-52 studies (clinicaltrials.gov, NCT02898454/NCT02912468) in patients with severe CRSwNP. This post hoc analysis investigated the effect of dupilumab on olfaction using UPSIT smell impairment categories. Methods Patients with baseline smell impairment (UPSIT ≤34/≤33 [women/men; score range 0–40] AND LoS score ≥1 [0–3] AND smell/taste item of the 22-item Sinonasal Outcome Test >0 [SNOT-22; 0–5]) treated with dupilumab 300 mg or placebo once every 2 weeks on background intranasal corticosteroids were analyzed. Results Of 724 patients, 665 (91.9%) had smell impairment at baseline; most had anosmia (UPSIT 0–18) (dupilumab/placebo: 80.9%/79.8%). At Week 24, the proportion of dupilumab-treated patients with anosmia decreased to 28.5%, while 14.9% achieved normosmia; most placebo-group patients (79.2%) remained anosmic and only 1.2% achieved normosmia (odds ratio: 17.3 [95% confidence interval: 5.1, 59.0]; p<.0001); results were similar at Week 52. Improvements in Nasal Polyps Score, nasal congestion, and SNOT-22 total score were moderately correlated with improvements in UPSIT at Weeks 24 and 52 (r = −0.38 to −0.50). Conclusion Most patients with severe CRSwNP had anosmia at baseline. Dupilumab treatment significantly improved smell versus placebo, with 14.9% achieving normosmia by Week 24. There was a trend for better clinical outcomes in patients with greater smell improvement.

Anatomical Variations on NCCT Nose and Paranasal Sinuses and Their Relation with Symptoms of the Patients: A Retrospective Analysis

Background: There are various bones around the nasal cavity that pneumatize to form the paranasal sinuses; namely, maxilla, ethmoid bone, frontal bone, and sphenoid bone. The CT scan of nose and paranasal sinus is the gold standard investigation for the patients of chronic rhino-sinusitis (CRS). Objective: This study was conducted with aim to determine the prevalence anatomical variation of Nose and Paranasal Sinuses on CT-scan and their relation with symptoms. Methods: A retrospective study was conducted among 200 patients over a period of one year (2022-2023). Patients with various symptoms of chronic rhinosinusitis were subjected to non-contrast enhanced Computed Tomography of nose and paranasal sinuses. Results: In our study 56% patients had septal deviation with most common C shaped deviation followed by S shaped deviation. 99.5% patients have agger nasi cells. The attachment of uncinate process was to the lamina papyracea in 83.0%, followed by the base of skull in 13.0%. The least common types were free uncinate process in 1.5%. The prevalence of concha bullosa was found 16.5%. However, paradoxical turbinate was present in 2.0% subjects. The incidence of Haller cells was found to be 5.0% and Onodi cells were found in 4.5%. The type of frontal cell was Agger Nasi followed by a Supra-bullar. In Sphenoid sinus, commonest type was pre-sellar type of pneumatisation. Conclusion: Our study concluded these various anatomical variations and its prevalence. The relation of variations with disease symptomatology is inconclusive.

Orthonasal and retronasal olfactory function in patients with chronic rhinosinusitis without nasal polyps undergoing endoscopic sinonasal surgery.

Olfactory dysfunction (OD) is a key symptom of chronic rhinosinusitis (CRS). Although extensively studied in CRS with nasal polyps (CRSwNP), OD in CRS without nasal polyps (CRSsNP) remains under-researched. This study aims to assess the prevalence of OD and its evolution in surgically naïve patients with CRSsNP undergoing endoscopic sinus surgery (ESS). This prospective study included 97 participants with CRSsNP (mean age, 46.5 years; 70.1% men) and 97 healthy controls (mean age, 46.5 years; 70.1% men). Participants underwent psychophysical evaluations of orthonasal (using the Sniffin' Sticks test) and retronasal olfaction (using powdered aromas) at enrolment and 6 months post-ESS. Out of 97 patients, 81 (83.5%) completed all assessments. At enrolment, 23 (28.4%) CRSsNP patients had OD based on composite threshold, discrimination, identification scores, compared with 7 (8.6%) controls (absolute % difference, 19.8% [95% CI, 8.2-31.4]). Retronasal olfactory function was also significantly worse in CRSsNP patients. Six months post-ESS, 30 patients (37.0%) experienced a clinically significant improvement in olfactory, whereas nonsignificant changes were observed in retronasal olfactory score, and 3.7% of patients experienced a deterioration of the olfactory function. In conclusion, although 37% of patients experienced a clinically significant improvement in their sense of smell following ESS, the overall prevalence of OD in this surgically naive population appears relatively low, especially when compared to that observed in patients with CRSwNP. Therefore, ESS may offer some benefits for enhancing orthonasal olfactory function, but the extent of these improvements appears to be limited.

Relationship between chronic rhinosinusitis and risk of obstructive sleep apnea

The relationship between obstructive sleep apnea (OSA) and chronic rhinosinusitis (CRS) has not yet been fully elucidated. Therefore, the objective of this study was to evaluate the connection between OSA risk and CRS by investigating associations between the STOP-Bang questionnaire and presence of CRS in a nationwide, population-based study. This is a cross-sectional study based on the Korean National Health and Nutrition Examination Survey (KNHANES). We evaluated 10,081 subjects who completed both the STOP-Bang and CRS-related questionnaires. Among the total subjects, 390 (3.9%) were CRS patients. The median STOP-Bang score was 3.0 [2.0; 4.0] in CRS patients, compared to 2.0 [1.0; 3.0] in subjects without CRS. In a low-risk group according to the STOP-Bang questionnaire, 3.1% of subjects were CRS patients. However, a gradual increase was observed among different risk groups. In the higher risk group, CRS patients accounted for 5.3% (P < 0.001). Among the four main symptoms of CRS (nasal obstruction, nasal discharge, facial pain/pressure, and decreased sense of smell), nasal obstruction (4.1 to 7.3%) and a decreased sense of smell (1.9 to 3.3%) increased with higher STOP-Bang scores. This study found that the proportion of patients with CRS was significantly higher in the group at a higher STOP-Bang score in the general population. Among symptoms of CRS, nasal obstruction and anosmia were found to be associated with an increased STOP-Bang score.

Nasal Symptoms of Chronic Rhinosinusitis Were Related to Its Nasoendoscopic Findings: A Retrospective Cohort Study at Dr. Soetomo General Academic Hospital, Surabaya

Highlights: Nasal congestion was the most common symptom presented in CRS patients. Nasal symptoms of CRS were positively associated with nasoendoscopic findings. Abstract Introduction: Chronic rhinosinusitis (CRS) is often encountered in Indonesia. Nasal endoscopy, or nasendoscopy, is considered the gold standard for assessing the severity of CRS. However, as nasendoscopy is unavailable in Indonesia, only symptom assessments can be conducted at primary healthcare facilities. This study aimed to elucidate the relationship between nasoendoscopic findings based on the Lund-Kennedy score (LKS) and symptoms in CRS patients based on the visual analogue scale (VAS) score. Methods: This retrospective analytic study evaluated CRS cases identified in the Ear, Nose, and Throat (ENT) Outpatient Clinic of Dr. Soetomo General Academic Hospital, Surabaya, from July 2021 to July 2022. Statistical analysis was conducted using Spearman’s rank correlation test to identify the correlation (R-value) between LKS and the VAS score. Statistical significance was achieved if p-value &lt;0.05. All statistical tests were conducted using the International Business Machines Corporation (IBM) Statistical Package for the Social Sciences (SPSS) version 26.0 for Windows. Results: A total of 57 CRS patients were included in this study, mostly females (64.9%) and those aged 50–59 years old (26.9%). Nasal congestion was the dominant nasal symptom (80.7%), with mostly moderate symptom severity (VAS 4-7) reported. Across both nasal cavities, the most frequent nasoendoscopic finding among CRS patients was nasal edema (82.4% and 93%). A positive and weak correlation existed between the total VAS score of all symptoms and the total LKS of both nasal cavities (r = 0.387, p &lt; 0.05). Conclusion: The nasal symptoms of CRS patients were significantly associated with its nasoendoscopic findings.

The validity of clinical guidelines and nasal endoscopy in the diagnosis of chronic rhinosinusitis—a prospective observational study

BackgroundChronic rhinosinusitis is a common disease entity seen by ENT surgeons as well as general practitioners all over the world. This study is aimed to evaluate and validate whether the clinical guideline symptoms (set by AAO-HNS 2015) alone and/or nasal endoscopic findings can predict the diagnosis of CRS, taking CT as the gold standard.MethodsA total of 118 patients with symptoms of chronic rhinosinusitis were taken. They were divided into two groups on the basis of whether they fulfilled the Guideline symptom criteria laid down by AAO-HNS in 2015 for diagnosing chronic rhinosinusitis. Each group underwent diagnostic nasal endoscopy (DNE), and patients with either purulence, edema in the middle meatus or ethmoid, and polyps in the nasal cavity or middle meatus were considered positive for DNE. A Lund-Mackay CT score of > 4 was considered diagnostic of CRS. Each group was analyzed separately. Sensitivity, specificity, and positive predictive value of guideline symptom with and without the addition of nasal endoscopy was recorded taking CT as the gold standard.ResultsNasal obstruction was the most common seen in all cases (100%) followed by headache in 45 (38.1%), facial pain in 32 (27.1%), anterior nasal discharge in 28 (23.7%), decreased sense of smell in 22 (18.6%), and posterior nasal discharge in 19 (16.1%). Two-thirds of patients (78, 66.1%) fulfilled the clinical guideline symptoms criteria, and one-third of patients (40, 33.9%) did not fulfill the clinical guideline symptoms criteria. A positive finding on DNE was found in 59.3% (n = 70) of patients. More than half of patients (62, 52.5%) had mild grade on endoscopic examination, while only 8 (6.8%) had moderate grade, and none had severe grade. Guideline symptoms have a high sensitivity (80%) but a low specificity (50.94%) in the diagnosis of CRS, with a fair level of agreement with CT diagnosis (Kappa = 0.32). DNE has a moderate sensitivity (72.31%) but a low specificity (56.60%) in the diagnosis of CRS, with a fair level of agreement with CT diagnosis (Kappa = 0.29). Sensitivity and specificity were 80.77% and 57.69% respectively when guideline symptoms and DNE findings are taken in series.ConclusionWe conclude that neither Guideline Symptom Criteria nor DNE is independently sufficient enough to have a high diagnostic accuracy for CRS. Comparing the diagnostic efficiency among various modalities, we report that in patients who meet guideline symptom criteria for CRS, the addition of nasal endoscopy turned out to be a cost-effective diagnostic approach and improves the diagnostic accuracy of DNE for CRS reasonably, hence should be emphasized as a diagnostic tool in the evaluation of patients for CRS.

Overall symptom severity as a patient-reported outcome measure for chronic rhinosinusitis: what it reflects and how to measure it.

The objective of this study was to identify how - and to what extent - overall symptom severity (OSS) score reflects individual chronic rhinosinusitis (CRS) symptoms and whether it can be measured using alternatives to the standard visual analog scale (VAS). CRS patients from four sites across three continents rated their OSS scores, severities of nasal obstruction, nasal drainage, decreased sense of smell, facial pain/pressure and sleep disturbance using a standard VAS, VAS with labeled tick marks at every 1 centimeter, and by writing down their OSS on a scale of 0 - 100 (which was divided by 10), all of which lead to severity scores ranging from 0 - 10 in 0.1 intervals. Quality of life was measured using the SNOT-22 and EQ-5D VAS. In 311 CRS patients, OSS score was significantly correlated with SNOT-22 and EQ-5D VAS. OSS score was most greatly associated with the mean of all individual symptom severity scores. From individual CRS symptoms, OSS was most greatly associated with nasal obstruction followed by nasal drainage and facial pain/pressure severities. These results held true for participants with and without nasal polyps. Measurement of OSS and individual symptom severity scores using a standard VAS, tick-marked VAS, and write-in option had near-perfect consistency. We demonstrate for the first time that OSS largely reflects the mean of individual CRS symptom severities, although OSS is=== most weighted by nasal obstruction severity. OSS and individual symptom severity scores can be measured using a standard VAS, tick-marked VAS or write-in prompt with near-perfect consistency.

Nasal resistance and inflammation: mechanisms for obstructive sleep apnea from chronic rhinosinusitis.

We have previously estimated that the prevalence of obstructive sleep apnea (OSA) among World Trade Center rescue and recovery workers is 75% and identified that having symptoms of chronic rhinosinusitis (CRS) is an independent risk factor for OSA in this population. Nasal inflammation and/or elevated awake nasal resistance that carried over into sleep could explain this association. To understand the mechanism(s) for the elevated risk of OSA observed in World Trade Center responders with CRS symptoms we examined if elevated awake supine nasal resistance was associated with OSA, CRS and/or nasal inflammatory biomarkers. A total of 601 individuals (83% male, average age 53 years, body mass index = 29.9 ± 5.5 kg/m2) enrolled in the World Trade Center Health Program and without significant snoring prior to September 11, 2001 underwent 2 nights of home sleep apnea testing, measurements of anterior rhinomanometry in the supine position, and nasal lavage. Awake supine nasal resistance was not associated with OSA; 74.8% and 74.4% of the participants with low and high nasal resistance respectively, had OSA. Patients with CRS had elevated nasal inflammatory markers (interleukin 6, interleukin 8, eosinophilic cationic protein, and neutrophil) but did not have high nasal resistance. Nasal inflammatory markers were not correlated with nasal resistance. As awake nasal resistance did not explain the relationship of CRS to OSA in this large and well characterized dataset, our findings suggest that either "sleep" nasal resistance or other factors such as increased supraglottic inflammation, perhaps through impairing upper airway reflex mechanisms, or systemic inflammation are involved in the pathophysiology of OSA in the World Trade Center population.

Sinonasal immunoglobulin G4-related disease: a case report of an atypical and rare entity

BackgroundImmunoglobulin G4-related disease is marked by extensive inflammation and fibrosis of an unknown autoimmune component, with an overall incidence ranging from 0.78 to 1.39 per 105 person-years. Sinonasal immunoglobulin G4-related disease is atypical and exceedingly uncommon in the existing literature, frequently manifesting clinically as chronic rhinosinusitis, epistaxis, and facial pain.Case presentationThis report describes a 25-year-old Iraqi female who has been suffering from symptoms of chronic rhinosinusitis for 8 years. Despite undergoing several surgeries, there has been no improvement in her symptoms. A tissue biopsy that revealed dense lymphoplasmocytosis with noticeable plasma cell infiltration, storiform fibrosis, and obliterative angitis, along with positive immunohistochemical staining for Immunoglobulin G4 plasma cells, finally confirmed the diagnosis of sinonasal immunoglobulin G4-related disease. The patient responded well to oral prednisolone and methotrexate treatments.ConclusionsThe main objective of the current report is to raise awareness among physicians about the significance of promptly identifying and diagnosing this rarity, thus preventing the adverse consequences linked to delayed diagnosis and treatment initiation.

The criteria for chronic rhinosinusitis in children with cystic fibrosis are rarely fulfilled after initiation of CFTR modulator treatment.

The vast majority of people with cystic fibrosis (pwCF) have untreated secondary chronic rhinosinusitis (CRS). Whereas the introduction of the cystic fibrosis transmembrane conductance regulator modulator (CFTRm) treatment regime has improved the lung function of pwCF, few studies have been published examining the effect on sinonasal symptoms in children. Our aim was to explore the effect of double CFTRm treatment on CRS and olfaction in children with CF. pwCF were included in this non-randomized cross-sectional study, where an otolaryngologist performed a complete ENT examination before initiating treatment with elaxacaftor/tezacaftor/ivacaftor (ETI). Twenty-three pwCF aged 6-12 years were included. Eighteen of 23 patients were on a double CFTRm treatment, and 5 patients were CFTRm naive, respectively. Altogether, 19 had normal olfaction, 20 had none or mild CRS symptoms according to SNOT-22, and 14 had a normal endoscopy. None of the patients had symptoms of chronic rhinosinusitis lasting for more than 12 weeks, thus none of the patients fulfilled the criteria for CRS. Children with CF treated with double CFTRm have few to no symptoms of CRS and normal olfaction, which is an improvement compared with children following treatment modalities prior to CFTRm.

Prevalence of Chronic Rhinosinusitis in the Jazan Region of Saudi Arabia

Background: Chronic rhinosinusitis (CRS) is one of the most common medical problems worldwide. It has a significant impact on the quality of life and productivity of many people. The prevalence of CRS varies throughout the world. In this study, we evaluated the prevalence of CRS in the Jazan region of Saudi Arabia. Methods: We conducted a cross-sectional study, using an online questionnaire to collect data on demographic, Sinonasal outcome test-22 (SNOT-22), chronic diseases, and smoking status. The prevalence was estimated based on the established diagnosis and a high SNOT-22 score with the presence of three of the cardinal symptoms of CRS. Variables associated with the presence of CRS were evaluated. Results: The 1081 contributors that met our inclusion criteria included 594 males and 487 females with a median (interquartile range) age of 31 (17) years. More than half of all participants (n = 653, 60.4%) had high SNOT-22 (&gt;18/110), but many did not fulfill the criteria for CRS in this study. Of the 1081, 215 had an established diagnosis and had three or more of the cardinal symptoms of CRS. In addition, 134 cases had not been clinically evaluated before but were suffering from three or more of the cardinal symptoms of CRS. Based on this, the estimated prevalence of CRS among our sample was 349 CRS patients (32.3%). CRS was less in people from mountainous areas (24.8%, P = 0.020). Conclusions: CRS was more prevalent in the hotter plains and coasts than in the mountains. Further studies are warranted to estimate the annual incidence and the impact on the health-care services as well as on the occupational and personal lives of the individuals.

Association of mucus eosinophil-derived neurotoxin levels with disease control status in patients with chronic rhinosinusitis.

Identifying the biomarkers for uncontrolled chronic rhinosinusitis (CRS) is important for directing treatment decisions. Eosinophilia has been reported to be involved in the poor disease control of CRS and mucus eosinophil-derived neurotoxin (EDN) is potentially a biomarker of intense eosinophil activation. This study aimed to assess the relationship between mucus EDN levels, disease severity, and degree of CRS control. A total of 150 adult patients with CRS and 25 healthy controls were prospectively enrolled. The nasal mucus and tissue specimens were collected to analyze EDN levels. Disease severity was assessed by Lund-Mackay score and 22-item Sino-Nasal Outcome Test (SNOT-22) score. Five CRS symptom severities during the prior month (nasal blockage, rhinorrhoea/postnasal drip, facial pain/pressure, smell, sleep disturbance or fatigue), use of rescue medications in the last six months, and the presence of diseased mucosa on nasal endoscopy were obtained. Consistent with the European Position Paper on Rhinosinusitis and Nasal Polyps 2020 CRS control criteria, uncontrolled CRS was defined as meeting at least three items. 40% of patients with CRS presented with uncontrolled status. Patients with uncontrolled CRS had significantly higher nasal mucus EDN levels (P = 0.010), percentage of blood eosinophil (P = 0.015), SNOT-22 score (P < 0.001), Lund-Mackay score (P = 0.008), and a more eosinophilic dominant phenotype of CRS (P < 0.001) than patients with controlled CRS. Furthermore, mucus EDN levels were positively correlated with blood eosinophils (r = 0.541, P = 0.005), SNOT-22 score (r = 0.460, P = 0.021), and Lund-Mackay score (r = 0.387, P = 0.039). Mucus EDN levels were the significant parameter related to uncontrolled CRS in multivariable analysis after adjusting for patient demographics and comorbidities (odds ratio = 1.323; P = 0.004). Mucus EDN levels may be a potential biomarker for identifying the CRS control status.

Antiseptics in otorhinolaryngology-asubstance overview

For preoperative skin antisepsis, alcohol-containing iodine solutions and octenidine are suitable. For wound antisepsis, polyhexanide and hypochlorous acid (HOCL) are also available, but only PVP-iodine and HOCL can be applied to cartilage. Chlorhexidine should only be used as mouth- and bodywash for Staphylococcus aureus (MRSA) decolonization. For the many other throat antiseptics, evidence of clinical efficacy is lacking. For decolonization of the nares, polyhexanide and octenidine are available as nasal gels, but these are inferior to mupirocin for MRSA decolonization. PVP-iodine and HOCL are safe to use for nasal irrigation, but only HOCL has proven effective to improve symptoms of chronic rhinosinusitis. All antiseptics exhibit acertain ototoxicity. With an intact eardrum, acetic acid-containing eardrops can be used to prevent and treat external otitis and myringitis. When the eardrum is perforated, only alcohol-free PVP-iodine and HOCL may be used.

Assessing the effect of absorbable steroid sinus implant: a state-of-the-art systematic review.

Endoscopic sinus surgery is not a definitive treatment for chronic rhinosinusitis (CRS). The use of sinus stents after surgery to maintain sinus patency and deliver local steroids has gained popularity. The first steroid-eluting bioabsorbable implant (SEBI) approved for this indication, later Propel, was developed in 2011. This state-of-the-art review aims to summarize the available evidence, as well as to point out potential pitfalls and lack of specific analyses to guide future research on this new therapeutic option. Pubmed (Medline), the Cochrane Library, EMBASE, SciELO. Nine research questions were defined: Are steroid-eluting Sinus implants useful for the control of CRS symptoms after surgery? Do they improve surgical field healing after CRS surgery? Do they decrease polyp regrowth after ESS? Do they decrease the need for ESS? Are they useful in symptom control as in-office procedure? Are they better than other steroid-impregnated resorbable materials? Do they have a positive impact on olfaction? Are they safe? Are they cost-effective? Retrieved articles were reviewed by two authors. Twenty nine studies were included: 3 metanalysis, 1 systematic review, 10 randomized clinical trials, 4 quasi-experimental studies, 1 retrospective cohort study, 4 cost studies, 3 case seriesand 2 expert consensus. The review encompassed a population of 3,012 patients treatedwith SEBI and 2826 controls. This is the first state-of-the-art review assessing steroid eluting bioabsorbable stent evidence. Despite the effort in recent years, still several questions remain unanswered. This review will hopefully guide future research efforts to better define the role of SEBI in the otolaryngology practice.

Сhronic rhinosinusitis in adult patients with cystic fibrosis receiving CFTR modulators

Cystic fibrosis-associated chronic rhinosinusitis (CRS) is a separate form of CRS that progresses gradually over the course of patient’s life and worsens with age. The reasons for this are the mechanical congestion of mucus in the paranasal sinuses and the persistence of colonies of pathogenic antibiotic-resistant microorganisms. Therapy with CFTR modulators has resulted in a significant reduction in the severity of CRS. The nature of these changes and the dynamics in the microbial landscape of the upper respiratory tract are not sufficiently explored.Aim of the article is to highlight various aspects of the impact of CFTR modulators on the course of CRS in adult patients with cystic fibrosis (CF) based on literature data and a number of our own clinical observations. The article presents a series of clinical cases of CRS in adult CF patients treated with CFTR modulators for different periods of time.Conclusion. During targeted therapy with CFTR modulators, the symptoms of CRS are reversed due to the restoration of normal rheological properties of nasal secretions, the clinical picture improves, and the severity of CRS decreases. However, this type of treatment has no direct effect on the microbial landscape of the respiratory tract and requires additional interventions in the form of local and systemic antibacterial therapy. Therapy with CFTR modulators alters the course of CF in the nasal cavity, as well as in the pharynx and larynx.

Apoptosis and turnover disruption of olfactory sensory neurons in eosinophilic chronic rhinosinusitis.

Olfactory dysfunction (OD) is one of the important and difficult-to-treat symptoms of eosinophilic chronic rhinosinusitis (CRS), which is typically associated with type 2 inflammation where eosinophils (EOSs) function as both effectors and initiators. Eosinophilic infiltration in the olfactory mucosa (OM) is associated with severe OD, mucosal erosion, and more loss of olfactory sensory neurons (OSNs). Active EOS-derived cytokines, chemokines, and eosinophil granule proteins may lead to aggravation of inflammation, tissue damage, and impairment of the survival and regeneration of OSNs. Recent studies show that EOSs can lead to apoptosis of OSNs through axonal and neural body damage, turnover disorder of OSNs through the loss of immature OSNs and globose basal cells (GBCs), changed proliferative activity of horizontal basal cells (HBCs), and dysfunction of OSNs through the breakdown of neuroepithelial integrity and alteration of ion concentration in OSNs and mucin. In this review, we outline the current progress on the role of EOSs on OD in patients with eosinophilic CRS and the mechanism of EOS-associated injury of the OM and OSNs in experimental animal models with sinonasal inflammation. Further investigations on the molecular mechanisms of tissue eosinophilia-induced injury of OSNs are warranted to obtain new therapeutic targets and achieve better restoration of olfactory function.

Eosinophilic Granulomatosis with Polyangiitis (EGPA): A Case Report Presenting with Peripheral Polyneuropathy

Background: Eosinophilic granulomatosis with polyangiitis is a rare clinical condition with multiple organ involvement. We report a case of a 64-year-old male patient who presented with symptoms of chronic rhinosinusitis, numbness, and pain in both lower limbs, weight loss of 6 kg/3 months, and subcutaneous vasculitis lesions along the forearms and legs on both sides. The patient had peripheral eosinophilia with an eosinophil count of 11.6%, eosinophil count of 1.56G/l, positive pANCA test, and electromyography results showing damage to the left calf nerve, bilateral superficial peroneal nerve, and left deep peroneal nerve with axonal loss. Biopsy results of calf muscle showed chronic granulomatous vasculitis. The patient was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA) according to the ACR/EULAR 2022 criteria. The patient was given intravenous Methylprednisolone, followed by maintenance treatment with reduced doses of Corticosteroids and Methotrexate. The patient’s leg pain was significantly reduced, numbness in both lower limbs was reduced, and the patient’s quality of life was improved. Methods: clinical case report. Results: The patient’s peripheral polyneuropathy and subcutaneous vasculitis were significantly reduced after treatment with Corticosteroids and Methotrexate. Conclusion: Eosinophilic granulomatosis with polyangiitis is a rare clinical condition with manifestations of multiple organ damage. Timely detection and diagnosis help increase treatment effectiveness and improve clinical symptoms for patients.

Pulmonary functions, nasal symptoms, and quality of life in patients with primary ciliary dyskinesia (PCD).

Several factors may influence quality of life (QOL) for patients with primary ciliary dyskinesia (PCD). We aimed to evaluate the association between pulmonary functions, nasal symptoms and QOL in PCD patients. A prospective single center study. Patients performed spirometry, whole body plethysmography, forced oscillation technique (FOT), lung clearance index (LCI), 6-min walk test (6MWT), and filled two questionnaires: a specific PCD QOL questionnaire (PCD-QOL) and Sino-nasal outcome test (SNOT-22) questionnaire, assessing symptoms of chronic rhinosinusitis and health related QOL. Twenty-seven patients (56% females), age 19.4 ± 10.5 years were included; their, FEV1 was 74.6 ± 22.7%, and RV/TLC was (157.3 ± 39.3% predicted). Health perception and lower respiratory symptoms domains of PCD-QOL had the lowest score (median [IQR]: 50 [33.3-64.6] and 57.1 [38.9-72.2], respectively). FOT parameters correlated with several PCD-QOL domains. R5 z-score (indicating total airway resistance) and AX z-score (indicating airway reactance) correlated negatively with physical domain (r = -0.598, p = .001, and r = -0.42, p = .03, respectively); R5 z-score also correlated negatively with hearing domain (r = -0.57, p = .002). R5-20 z-score (indicating small airway resistance) correlated negatively with role domain (r = -0.49, p = .03). SNOT-22 score correlated negatively with several PCD-QOL domains (lower respiratory symptoms r = -0.77, p < .001; physical r = -0.72, p < .001; upper respiratory symptoms r = -0.66, p < .001). No correlations were found between spirometry values, LCI, 6MWT, and PCD-QOL. FOT suggested small airway dysfunction, and correlated negatively with several PCD-QOL domains. Nasal symptoms had strong negative correlations with PCD-QOL. Larger longitudinal studies will further elucidate factors affecting QOL in PCD.

PREVALENCE AND SYMPTOMS OF ASTHMA AND ALLERGIC RHINITIS IN ADULTS WITH CHRONIC RHINOSINUSITIS IN THE EASTERN REGION OF SAUDI ARABIA

Background: This cross-sectional study explores the prevalence and symptoms of asthma and allergic rhinitis among adults diagnosed with Chronic Rhinosinusitis (CRS) in the Eastern Region of Saudi Arabia. Methods: Involving 386 participants, the research employs demographic profiling and symptom analysis and explores the interplay of upper and lower airway conditions. This study investigates the prevalence of asthma and allergic rhinitis among 386 adults with chronic rhinosinusitis (CRS) in Eastern Saudi Arabia. Employing a cross-sectional design, participants from King Fahad Specialist Hospital and Jubail General Hospital were selected through random and stratified sampling. Results: The study reveals a higher prevalence of asthma (40.6%) compared to allergic rhinitis (25.1%), emphasising the need for a comprehensive understanding of these respiratory conditions. Intriguing associations between asthma attacks and specific CRS symptoms, such as chest tightness and waking due to shortness of breath, provide insights into shared pathways. Demographically, higher prevalence is observed among females, individuals with lower educational attainment, and nonsmokers, highlighting socio-demographic influences on respiratory health. Conclusion: The study discloses a noteworthy prevalence of asthma (40.6%) in comparison to allergic rhinitis (25.1%) among adults with Chronic Rhinosinusitis in Eastern Saudi Arabia. Asthma attacks showcase distinctive associations with specific CRS symptoms, emphasising the intricate interplay of these respiratory conditions. The demographic influences of education and smoking underscore the importance of lifestyle factors. Recommendations for future research include longitudinal studies and clinical validations to enhance the validity and depth of our findings.

Clinical Evaluation of &lt;i&gt;Pippalyadi Avapeeda Nasya, Elakanadi Kashaya&lt;/i&gt; and &lt;i&gt;Vyoshadi Ghrita&lt;/i&gt; in Chronic Rhinosinusitis: Case Series

Introduction: Chronic Rhino Sinusitis (CRS) is an inflammatory disease of the nose and sinuses with clinical features such as nasal blockage, nasal discharge and hyposmia.
