OBJECTIVE To predict biomarkers of type 2 inflammation in chronic rhinosinusitis with nasal polyps(CRSwNP)by employing peripheral blood indicators.METHODS CRSwNP patients admitted to the Rhinology Department of Beijing Tongren Hospital from June 2020 to May 2022 were enrolled and their basic clinical data were collected.The blood percentage of eosinophils(Eos%),Eos count,periostin and total IgE,as well as mucosal interleukin-5(IL-5)and Staphylococcus aureus enterotoxin-immunoglobulin E(SE-IgE)were tested.The receiver operating characteristic(ROC)curve was used to evaluate the predictive value of each blood indicator for positive mucosal expression of IL-5/SE-IgE.The logistic regression was employed to screen multiple blood indicators with predictive value for positive mucosal expression of IL-5/SE-IgE in order to construct a nomogram model.RESULTS The proportion of asthma,blood Eos%,periostin and total IgE in CRSwNP patients showed statistical differences between IL-5/SE-IgE positive and negative subgroups.ROC univariate analysis demonstrated that blood Eos%,Eos count,periostin and total IgE could predict mucosal IL-5 positivity with AUC ranging from 0.655 to 0.784,and mucosal SE-IgE positivity with AUC ranging from 0.721-0.802.The logistic regression confirmed that blood Eos%and total IgE,as well as blood periostin and total IgE were independent predictors for mucosal IL-5 and SE-IgE positivity,respectively.The nomogram models were constructed for predicting IL-5/SE-IgE positivity in CRSwNP mucosa,with consistency incides(C-index)of 0.804 and 0.81,indicating good predictive accuracy.CONCLUSION The nomograms constructed based on blood Eos%and total IgE,as well as blood periostin and total IgE,could have good predictive value for the positive mucosal expression of IL-5 and SE-IgE in the CRSwNP,which help to predict the severity of endotype and phenotype of CRSwNP.

OBJECTIVE To explore the clinical characteristic manifestation of Rosai-Dorfman disease(RDD)involving the nasal cavity and paranasal sinuses.METHODS The clinical data of 16 patients with RDD involving the nasal cavity and paranasal sinuses who received treatment in Department of Rhinology of Beijing Tongren Hospital Affiliated to Capital Medical University from December 2016 to December 2023,were retrospective analyzed.RESULTS The male to female ratio was 1:3,with an average age of 47.4 years and an average disease duration of 22.34 months.There were 14,3,5,6 and 1 patients who complained of nasal congestion,dry nose,decreased sense of smell,head and face pain,and bulging/diplopia,respectively.There were 9 patients who had external nasal swelling.There were 14 RDD patients who were involved at least the nasal septum,12 patients who were simply affected in the nasal cavity,and 3 cases who involved the paranasal sinuses.There was 1 case belonged to a mixed type of RDD.There were 8 of 10 cases who were misdiagnosed or missed due to intraoperative rapid freezing.Endoscopic examination showed bilateral bulging in 9 patients'nasal septum,and nodular or granular new growth on 7 patients'nasal floor and inferior turbinate surface.Sinus CT found 9 patients'the nasal septum area showed a circular uniform soft tissue shadow or symmetrical soft tissue thickening shadow,5 patients'nasal floor and inferior turbinate showed obvious soft tissue thickening shadow.CONCLUSION RDD involving the nasal cavity and paranasal sinuses has certain typical features in external nasal manifestations,endoscopic and imaging examinations.Comprehensive judgment can help improve the feasibility of clinical diagnosis of RDD.

Objective:To investigate whether changes in postoperative symptoms and signs in patients can predict the recurrence of ECRS after nasal endoscopic sinus surgery. Methods:A total of 70 adult patients with ECRS were enrolled for ESS surgery from June 2020 to March 2022 in a single center. There were 50 males and 20 females, with an average age of （46.9±14.5） years. Follow-up after ESS was at least 52 weeks. Patients undergo peripheral blood tests, CT of the sinuses, olfactory T&T test, visual analogue scale of symptoms（VAS）, and endoscopic scoring. Results:VAS scores and endoscopic scores were analyzed at preoperative and 6th week, 12th week, 24th week and 52th week postoperative. After 12th week postoperatively, there was a clear correlation between symptom scores and endoscopic scores. Moreover, olfactory disorder and nasal discharge were the two most obvious symptoms. There were differences in the expression of multiple preoperative clinical inflammatory indicators between the symptom-controled group and the symptom-uncontrolled group（previous surgical history, concomitant asthma, nasal smear eosinophil, serum EOS%, total IgE, CT score, olfactory score, and symptom score, all with P<0.05）, while there was no difference in baseline endoscopic score（P>0.05）. At 12th week postoperative, the two groups of patients showed significant differences in both symptom scores and endoscopic scores. The symptoms and endoscopic score at the 12th week point of follow-up were used as predictive indicators for recurrence, with sensitivity and specificity of 62.5% and 83.3%, respectively. Conclusion:The changes in postoperative symptom score and endoscopic score in ECRSwNP patients indicated that the recurred ECRS. In the symptom-uncontrolled group, symptomatic and endoscopic scores showed consistent increased scores; In the symptom-controlled group, conflicting results between increased endoscopic scores and stable symptoms suggest that the presence of asymptomatic recurrence must be considered. The changes in symptoms and signs at the 12th week point of follow-up can serve as clinical indicators for preventing disease recurrence.

Chronic rhinosinusitis（CRS） is an inflammatory disease involving the mucosa of the nasal and paranasal sinuses for more than 12 weeks and can be classified as CRS with nasal polyp（CRSwNP） and CRS without nasal polyp（CRSsNP） depending on the phenotype. Clinical treatments reveal significant differences in disease prognosis and improvement in quality of life in patients with the same clinical phenotype. Inflammatory cells infiltration and inflammatory mediators are important factors driving CRS endotypes. In particular, CRS with predominantly eosinophilic infiltration and type 2 CRS present severe clinical symptoms, comorbidities, and high recurrence rates. CRS endotype-oriented treatment methods may better contribute to improving patient prognosis and quality of life. This article summarizes the current progress of CRS endotype research and reviews the endotype-oriented treatment options.

OBJECTIVE To test whether there are some differences among chronic rhinitis,chronic rhinosinusitis patients with nasal polyps(CRSsNP)and without nasal polyps(CRSsNP)in symptom severity,health-related quality-of-life impairment,and objective inflammatory factors.METHODS A total of 154 consecutive patients who had been treated at the Otolaryngology Department of Beijing Tongren Hospital from January 2017 to December 2018 were recruited in this study.The patients aged 18-70 years,with 106 males and 48 females.All patients performed endoscopic examination,nasal exhaled nitric oxide(nNO),skin prick test(SPT),sinus CT scan,complete blood count,and fulfilled the visual analogue scale(VAS)self-assessment of nasal symptoms and the SNOT-22 questionnaire under the guidance of the physician.According to the inclusion criteria,A total of 43 patients with CR,58 patients with CRSsNP and 53 patients with CRSwNP were enrolled in our study.RESULTS The total SNOT-22 score in CRSsNP group was significantly lower than that in CR and CRSwNP groups(30.0±19.4 vs.41.1±21.9,30.0±19.4 vs.40.9±18.7,P<0.05),and there was no significant difference between CR group and CRSwNP group.The average scores of nasal symptoms and extranasal symptoms in CRSwNP group were the highest;the scores in CRSsNP group were lower.The impact of CR patients on sleep damage was significantly higher than that in CRSsNP patients(9.9±6.2 vs.5.1±5.3,P<0.05),and there was no significant difference between CR group and CRSwNP group(9.9±6.2 vs.7.1±5.7,P>0.05).When patients suffered with positive SPT,there was no statistical difference in symptom scores and SNOT-22 scores between CR,CRSsNP,and CRSwNP;but with negative SPT,there was a significant statistical difference in both symptom scores and SNOT-22 scores among the three groups.CONCLUSION CR,CRSsNP and CRSwNP have a significant impact on quality of life,respectively.In terms of symptom scores and quality of life scores,the CR group and CRSwNP group are similar and the scores are higher than that of the CRSsNP group.However,the objective inflammation factors are not consistent with the subjective symptom scores and quality of life scores.
