Objective: To investigate the clinical efficacy and safety of anti-IgE monoclonal antibody (omazumab) in the treatment of allergic united airway disease (UAD) in the real-wold. Methods: Retrospective cohort study summarizes the case data of patients with allergic united airway disease who were treated with anti IgE monoclonal antibody (omalizumab) for more than 16 weeks from March 1, 2018 to June 30, 2022 in the Peking University First Hospital.The allergic UAD is defined as allergic asthma combined with allergic rhinitis (AA+AR) or allergic asthma combined with chronic sinusitis with nasal polyps (AA+CRSwNP) or allergic asthma combined with allergic rhinitis and nasal polyps (AA+AR+CRSwNP). The control of asthma was evaluated by asthma control test (ACT), lung function test and fractional exhaled nitric oxide (FeNO). The AR was assessed by total nasal symptom score (TNSS). The CRSwNP was evaluated by nasal visual analogue scale (n-VAS), sino-nasal outcome test-22 (SNOT-22), nasal polyps score (TPS) and Lund-Mackay sinus CT grading system. The global evaluation of omalizumab for the treatment of allergic UADwas performed by Global Evaluation of Treatment Effectiveness(GETE).The drug-related side effects were also recorded. Matched t test and Wilcoxon signed-rank test were used to compare the score changes of IgE monoclonal antibody (omazumab) before and after treatment, and multivariate logistic regression analysis was used to determine the influencing factors of IgE monoclonal antibody (omazumab) response. Results: A total of 117 patients with UAD were enrolled, ranging in age from 19 to 77 years; The median age of patients was 48.7 years; Among them, 60 were male, ranging from 19 to 77 years old, with a median age of 49.9 years; There were 57 females, ranging from 19 to 68 years old, with a median age of 47.2 years. There were 32 cases in AA+AR subgroup, 59 cases in AA+CRSwNP subgroup, and 26 cases in AA+AR+CRSwNP subgroup. The total serum IgE level was 190.5 (103.8,391.3) IU/ml. The treatment course of anti IgE monoclonal antibody was 24 (16, 32) weeks. Compared with pre-treatment, omalizumab increased ACT from 20.0 (19.5,22.0) to 24.0 (23.0,25.0) (Z=-8.537, P<0.001), increased pre-bronchodilator FEV1 from 90.2 (74.8,103.0)% predicted value to 95.4 (83.2,106.0)% predicted value (Z=-5.315,P<0.001), increased FEV1/FVC from 80.20 (66.83,88.38)% to 82.72 (71.26,92.25)% (Z=-4.483,P<0.001), decreased FeNO from(49.1±24.8) ppb to (32.8±24.4) ppb (t=5.235, P<0.001), decreased TNSS from (6.5±2.6)to (2.4±1.9) (t=14.171, P<0.001), decreased n-VAS from (6.8±1.2) to (3.4±2.0)(t=14.448, P<0.001), decreased SNOT-22 from (40.0±7.9) to (21.3±10.2)(t=15.360, P<0.001), decreased TPS from (4.1±0.8) to (2.4±1.0)(t=14.718, P<0.001) and decreased Lund-Mackay CT score from (6.0±1.3) to (3.1±1.6)(t=17.012, P<0.001). The global response rate to omalizumab was 67.5%(79/117). The response rate in AA+AR (90.6%,29/32) was significantly higher than that in AA+CRSwNP (61.0%,36/59) and AA+AR+CRSwNP (53.8%,14/26) subgroups (χ²=11.144,P=0.004). Only 4 patients (3.4%,4/117) had mild side effects. Conclusion: The real-world study showed favorable effectiveness and safety of anti-IgE monoclonal antibody for treatment of allergic UAD. To provide basis for preventing the progress and precise treatment of allergic UAD.

Objective:To analyze the differential expression of neural precursor cell-expressed developmentally downregulated 8（NEDD8） protein in nasal polyp tissues of patients with different pathological types of chronic rhinorhinosinusitis with nasal polyps（CRSwNP）. Methods:All specimens were obtained from the specimen library of Beijing Tongren Hospital, and were all patients who underwent nasal endoscopic surgery for chronic rhinosinusitis in Beijing Tongren Hospital. Hematoxylin-eosin staining（HE） was used to detect the number of eosinophils in nasal polyps, and CRSwNP patients were grouped according to the number of eosinophils in nasal polyps, immunohistochemistry was used to detect and analyze the expression level of NEDD8 protein in nasal polyps. Results:The expression level of NEDD8 protein in nasal polyps of patients with eosinophilic chronic rhinorhinosinusitis with nasal polyps was significantly higher than that of patients with non-eosinophilic chronic rhinosinusitis and nasal polyps（P<0.05）. In addition, there was a significant positive correlation between the expression level of NEDD8 protein and the number of eosinophils in nasal polyp tissue（r=0.79, P=0.02）. Conclusion:There are differences in the expression of NEDD8 protein in patients with chronic rhinosinusitis and nasal polyps of different pathological types.

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 compare the value of 25-hydroxyvitamin D3 (25-(OH)D3) with other clinical parameters in the prediction and diagnosis of eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP). Methods: Eligible chronic rhinosinusitis with nasal polyps (CRSwNP) patients and healthy subjects in the Affiliated Hospital of Guizhou Medical University from January to April of 2021 were included for this study. The age, gender, past history and other basic characteristics of all subjects were recorded. The CRSwNP patients were classified into ECRSwNP and non-eosinophilic chronic rhinosinusitis with nasal polyps (nECRSwNP) endotypes by the percentage of tissue eosinophils. Serum 25-(OH)D3 levels measurements were performed in all subjects. Paranasal sinus CT scans, blood eosinophil counts, and determination of total immunoglobulin E (total IgE), Th1/Th2 plasma cytokines and nasal nitric oxide (nNO) levels were performed before surgery. Logistic regression analysis was used to evaluate the related factors of ECRSwNP. Receiver operating characteristic (ROC) curves was used to evaluate the predictive potential of the clinical parameters. Results: One hundred and twenty-seven CRSwNP patients and 40 healthy subjects were recruited, including 74 males and 93 females of the patients, with the age of (38.73±13.05) years. In patients with ECRSwNP, serum 25-(OH)D3 levels were significantly lower than those in nECRSwNP patients ((26.14±4.58) ng/ml vs (35.71±7.86) ng/ml, t=-8.564, P<0.01). The prevalence of asthma, prevalence of allergic rhinitis, peripheral blood eosinophil counts, total IgE levels, nNO levels and CT scores ratio for ethmoid sinus and maxillary sinus (E/M ratio) of ECRSwNP patients were significantly higher than those in nECRSwNP patients (all P<0.05). However, there was no significant difference in Th1/Th2 cytokines levels between the histological types of CRSwNP (all P>0.05). Among the predictive indicators, 25-(OH)D3 had the highest predictive value, with ROC area under curve (AUC) value of 0.882. The best cut-off point of 28.5 ng/ml for 25-(OH)D3 demonstrated a sensitivity of 0.871 and a specificity of 0.762 for ECRSwNP. Conclusion: Measurement of serum 25-(OH)D3 level may be used as an effective method to distinguish between ECRSwNP and nECRSwNP.

BACKGROUND: Maxillary sinusitis of odontogenic origin, also known as maxillary sinusitis of dental origin or odontogenic maxillary sinusitis (OMS), is a common disease in dental, otorhinolaryngologic, allergic, general, and maxillofacial contexts. Despite being a well-known disease entity, many cases are referred to otorhinolaryngologists by both doctors and dentists. Thus, early detection and initial diagnosis often fail to detect its odontogenic origin. MAIN BODY: We searched recent databases including MEDLINE (PubMed), Embase, and the Cochrane Library using keyword combinations of “odontogenic,” “odontogenic infection,” “dental origin,” “tooth origin,” “sinusitis,” “maxillary sinus,” “maxillary sinusitis,” “odontogenic maxillary sinusitis,” “Caldwell Luc Procedure (CLP),” “rhinosinusitis,” “functional endoscopic sinus surgery (FESS),” “modified endoscopy-assisted maxillary sinus surgery (MESS),” and “paranasal sinus.” Aside from the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) trial, there have been very few randomized controlled trials examining OMS. We summarized the resulting data based on our diverse clinical experiences. CONCLUSION: To promote the most efficient and accurate management of OMS, this article summarizes the clinical features of rhinosinusitis compared with OMS and the pathogenesis, microbiology, diagnosis, and results of prompt consolidated management of OMS that prevent anticipated complications. The true origin of odontogenic infections is also reviewed.

A fungus ball is the most common manifestation of fungal sinusitis. Bilateral involvement of fungus balls is rare, and bilateral sphenoid involvement is even more uncommon. The authors report two cases of bilateral fungus balls with sphenoid sinus involvement successfully treated with endoscopic sinus surgery. Both patients complained of nonspecific headache; diagnoses were made with CT and histopathological examinations, and surgical removal was achieved via transostial approach. Bilateral fungus balls involving the sphenoid sinus are rare but do occur; their removal is possible through endoscopic sinus surgery with a high cure rate. We thus recommend using CT scanning to identify typical findings of a sphenoid fungus ball even in bilateral paranasal sinusitis and perform aggressive surgical treatment.

A nasal septal abscess results from the collection of purulent fluid between the cartilage of bony septum and overlying mucoperichondrium or mucoperiosteum. Unless early diagnosis and surgical treatment are performed, serious complications such as cavernous sinus thrombophlebitis, sepsis, and saddle nose may occur. We report a case of septal abscess and sphenoid sinusitis that occurred after dental implant. A 74-year-old female with diabetes and liver cirrhosis was referred to the hospital for management of rapidly aggravated perinasal pain, nasal obstruction, and headache. The patient had undergone dental implant in the right upper incisor area 6 days ago. A CT revealed septal abscess and bilateral sphenoid sinusitis. The patient was operated upon to drain septal abscess, and both sphenoid sinuses were opened widely.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis that commonly affects the peripheral nervous system. EGPA rarely presents with acute polyneuropathy resembling Guillain-Barré syndrome (GBS). A 51-year-old female patient with a history of asthma suddenly developed bilateral lower extremityparesthesia that progressed to asymmetric ascending paralysis within 10 days of onset. Nerve conduction study results were compatible with acute motor sensory axonal neuropathy, consistent with a GBS subtype. A clinical and neurophysiological diagnosis of GBS was made, and high-dose intravenous immunoglobulins were administered. However, the patient's painful motor weakness persisted. Furthermore, she had newly developed skin lesions on her back, face, and arms. Her blood test revealed marked eosinophilia (>60%). In addition, antineutrophil cytoplasmic antibodies were reported positive. A Water's view radiographic image showed bilateral maxillary sinusitis. Considering the history of asthma, we suspected EGPA-associated polyneuropathy and started steroid treatment. The patient's strength and eosinophilia improved rapidly and dramatically. EGPA can mimic GBS and should be differentiated because of different treatment strategies. Early diagnosis and prompt treatment help achieve a good outcome.

OBJECTIVES: Pathophysiology of chronic rhinosinusitis (CRS) is very complex and has not yet been clearly understood. To date, various factors have been researched to have relations with the pathogenesis of CRS, such as superantigens and biofilms. Recently, we found an unusual pathological finding in patients with CRS, and we called this new entity as bacteria ball (or bioball). In this study, we analyze the clinical characteristics of bacteria ball occurred in CRS. METHODS: This study enrolled consecutive 247 patients with CRS who underwent functional endoscopic sinus surgery from January 2015 to August 2016. The diagnosis of bacterial ball was made when negative in Gomori-methenamine-silver stain and positive in Gram stain. Histologically, bacterial ball was defined as acellular mucous materials with bacterial colonies and inflammatory cell infiltrates. We compared clinical data and computed tomography (CT) findings between fungal and bacterial balls. RESULTS: Six cases (2.4%) of CRS were confirmed histologically as bacterial ball. Most of them were found in the maxillary sinus of CRS without nasal polyposis (66.7%). Bacterial ball was green or brown colored materials similar to fungal ball which was harder and tightly adherent to the antral mucosa. Compared to fungal ball, patients with bacterial ball showed significantly less peripheral eosinophils (P=0.011) and calcification in CT scans (P=0.003). CONCLUSION: Bacterial ball is unusual findings occurred in patient with CRS which is different from fungal ball and biofilm. For diagnosis of bacterial ball, Gram stain is essentially required to identify bacterial colonies. Bacterial ball might appear to be evidence of a new strategy for living in the paranasal sinuses.
