OBJECTIVES/HYPOTHESIS: The traditional criteria for the diagnosis of allergic fungal sinusitis include chronic rhinosinusitis, \"allergic mucin\" (mucus containing clusters of eosinophils), and detection of fungi by means of histological examination or culture. In 1999, a group of Mayo Clinic researchers, with a novel method of mucus collection and fungal culturing technique, were able to find fungi in 96% of patients with chronic rhinosinusitis. Immunoglobulin E-mediated hypersensitivity to fungal allergens was not evident in the majority of their patients. Because the presence of eosinophils in the allergic mucin, not a type I hypersensitivity, is probably the common denominator in the pathophysiology of allergic fungal sinusitis, the Mayo Clinic group proposed a change in terminology from allergic fungal sinusitis to eosinophilic fungal rhinosinusitis. Using new techniques of culturing fungi from nasal secretion, as well as preservation and histological examination of mucus, we investigated the incidence of \"eosinophilic fungal rhinosinusitis\" in our patient population. STUDY DESIGN METHODS: In an open prospective study nasal mucus from patients with chronic rhinosinusitis as well as from healthy volunteers was cultured for fungi. In patients, who underwent functional endoscopic sinus surgery, nasal mucus was investigated histologically to detect fungi and eosinophils within the mucus. RESULTS: Fungal cultures were positive in 84 of 92 patients with chronic rhinosinusitis (91.3%). In all, 290 positive cultures grew 33 different genera, with 3.2 species per patient, on average. Fungal cultures from a control group of healthy volunteers yielded positive results in 21 of 23 (91.3%). Histologically, fungal elements were found in 28 of 37 patients (75.5%) and eosinophilic mucin in 35 of 37 patients (94.6%). Neither fungi nor eosinophils were present in 2 of 37 patients (5.4%). CONCLUSIONS: Our data show that the postulated criteria of allergic fungal sinusitis are present in the majority of patients with chronic rhinosinusitis. Either those criteria will be found to be invalid and need to be changed or, indeed, \"eosinophilic fungal rhinosinusitis\" exists in the majority of patients with chronic rhinosinusitis. Based on our results, fungi and eosinophilic mucin appear to be a standard component of nasal mucus in patients with chronic rhinosinusitis. 相似文献

Structured histopathology (SHP) is a method of analyzing sinonasal tissue to characterize endotypes of chronic rhinosinusitis with nasal polyps (CRSwNP). Allergic fungal rhinosinusitis (AFRS) shares several features with certain endotypes of CRSwNP. Our objective was to compare the histopathology of AFRS and eosinophilic CRSwNP to further understand whether they are separate endotypes or disease entities altogether. 相似文献

OBJECTIVES: Chronic rhinosinusitis with nasal polyposis (CRSwNP) and asthma share characteristic inflammatory features and histopathologic findings of airway remodeling. Remodeling, which is controlled by matrix metalloproteinases (MMP), is a key event in the pathogenesis of asthma. The MMP functions have rarely been evaluated in CRSwNP. STUDY DESIGN: Prospective and in vivo. METHODS: MMP-7, MMP-8, MMP-9, and tissue inhibitor of metalloproteinase (TIMP)-1 concentrations were analyzed by enzyme-linked immunosorbent assay and their molecular forms by Western immunoblotting and gelatin zymography in 24 patients operated on for CRSwNP and in nasal lavages from 19 healthy controls. MMP function, protective or destructive, was evaluated by comparing MMP/TIMP-1 levels with the disease activity, estimated by tissue eosinophilia and a need for re-operations. RESULTS: Significantly increased levels of MMP-8/TIMP-1 and MMP-9/TIMP-1 were found in patients without tissue eosinophilia relative to eosinophil-positive CRSwNP patients and controls, as well as in patients who did not require re-operation in comparison with re-operated patients. In eosinophil-positive and re-operated patients, these parameters were within the same range than in controls. CONCLUSIONS: Proteolytic spectrum is different in eosinophilic and noneosinophilic CRSwNP, suggesting a new mechanism for eosinophil accumulation in the disease pathogenesis. Enhanced MMP-8 and MMP-9 expression was associated with a better prognosis/clinical outcome, and thus these results may represent a synergic, protective role of MMP-8 and MMP-9 in host response in CRSwNP. Because synthetic MMP inhibitors, capable of equilibrating the unfavorable MMP/TIMP-ratio, may be of potential therapeutic value in chronic respiratory tract diseases, the MMP functions in inflammatory conditions need to be carefully established. 相似文献

BackgroudAspirin-exacerbated respiratory disease (AERD) is a difficult-to-treat syndrome where timely diagnosis and initiation of disease-specific therapies are pertinent to improved patient outcomes.ObjectiveTo characterize the most common timeline for development of the clinical triad [asthma, nasal polyposis, and reactions to nonsteroidal anti-inflammatory drugs (NSAIDs)], identify barriers to prompt diagnosis of AERD, and describe indications for an aspirin challenge to facilitate accurate diagnosis.MethodsSix hundred ninety-seven patients with diagnosed AERD and history of at least one sinus surgery to remove nasal polyps were identified in the Brigham and Women's Hospital AERD registry. Patient reported age at disease onset of asthma, nasal polyposis, and age of first NSAID reaction were obtained from 2013 to 2019 at enrollment.ResultsOf the 697 patients identified, diagnosis of asthma preceded diagnosis of nasal polyposis and first NSAID reaction, although there was considerable variability between patients.ConclusionsPrompt diagnosis of AERD is important for patient and provider education and improved care of this difficult-to-treat population of patients. Consider diagnostic aspirin challenge in patients without historical reactions to NSAIDs who have an otherwise compatible clinical history, specifically in patients who take daily low-dose aspirin, leukotriene modifiers, avoid NSAIDs, or who are severely symptomatic at baseline where it would be difficult to identify an acute worsening of symptoms. 相似文献

OBJECTIVES/HYPOTHESIS: Allergic fungal sinusitis and the role of fungi in the pathogenesis of chronic rhinosinusitis are topics of interest and controversy in rhinology. The classification of chronic rhinosinusitis as either a bacterial infection or an allergic (eosinophilic) reaction to fungi has significant implications for treatment of this disease process. We designed a study to determine whether standard isolation techniques, as employed in a university hospital mycology laboratory, could isolate and identify fungi in the intraoperative specimens from patients undergoing functional endoscopic sinus surgery for chronic rhinosinusitis. STUDY DESIGN: Forty-five random patients with a diagnosis of chronic rhinosinusitis by clinical and computed tomography criteria underwent endoscopic sinus surgery during 2001, performed by two senior surgeons (J.B.J., R.A.L.). Specimens of mucin, sinus secretions, and/or tissue were obtained intraoperatively and sent to the New York University Medical Center (New York, NY) mycology laboratory for isolation and identification of fungi. METHODS: Specimens were treated with Sputolysin and chloramphenicol; plated on Sabouraud, ChromAgar/Candida, Mycosel, and Niger seed agar plates; and incubated at 30 degrees C (or 37 degrees C) for up to 1 month. RESULTS: We were able to demonstrate the presence of fungi in 56% of intraoperative specimens obtained from patients undergoing surgery for chronic rhinosinusitis. CONCLUSIONS: Using a standard hospital mycology laboratory protocol, which is relatively inexpensive and readily available, fungus can be isolated from a majority of patients undergoing functional endoscopic sinus surgery for chronic rhinosinusitis. Educational statement: Discuss the possible role of fungus in chronic rhinosinusitis and evaluate the efficacy of documenting the presence of fungus in a routine fashion to encourage clinically relevant directed treatments.) 相似文献

OBJECTIVE: To investigate the efficacy of endoscopic sinus surgery (ESS) in the management of chronic sinusitis and asthma in patients with nasal polyps and steroid-dependent asthma. STUDY DESIGN: Retrospective chart review. METHODS: The study included 17 patients who underwent ESS with nasal polyps, steroid-dependent asthma with or without aspirin sensitivity and a minimum of 1 year postoperative follow-up. Nine patients were ASA sensitive, and eight patients were ASA tolerant. Chronic sinusitis and asthma were evaluated using subjective (patient complaints) and objective (computed tomography scans, pulmonary function tests, steroid doses) criteria. Preoperative data were compared with data obtained 12 to 18 months postESS. Tissue samples were graded for degree of inflammation and edema. RESULTS: Thirteen of the 17 (76.5%) patients reported improved clinical symptoms postESS. The postoperative Lund-Mackay scores were statistically lower for the 17 patients (P <.0001). The group experienced improvement in postoperative forced expiratory volume at 1 second (FEV1) (P <.014). Twelve of 17 (70.6%) experienced reduction in systemic steroid usage (P <.048). The ASA sensitive patients did not have a statistical improvement in postoperative FEV1 (P >.08) and sinonasal symptoms (P >.16) compared with the ASA tolerant group. Polyp tissue from the ASA sensitive patients demonstrated more edema and more inflammation on average than ASA tolerant polyps, but the results were not statistically significant. CONCLUSION: ESS demonstrates a beneficial effect on the sinonasal and asthma symptomatology in patients with nasal polyps and asthma using objective measures. Subset of aspirin-tolerant patients have statistically better outcome for sinonasal symptoms and pulmonary function testing than aspirin-sensitive patients. 相似文献

ObjectiveAspirin exacerbated respiratory disease (AERD) patients are challenging to manage with sinonasal and pulmonary symptoms refractory to maximal medical and surgical therapies. Our objective was to comprehensively examine objective and validated, disease-specific subjective sinonasal and pulmonary outcomes of aspirin (ASA) desensitization therapy in this patient population.MethodsProspective cohort study at an academic tertiary center. AERD patients with a history of chronic rhinosinusitis with nasal polyposis (CRSwNP), prior diagnosis of asthma, and a history of ASA sensitivity were eligible for inclusion. Patients underwent ASA desensitization using an established institutional protocol and continued on a 650 mg twice daily maintenance dose. Baseline Sinonasal Outcome Test (SNOT-22) and Asthma Control Questionnaire (ACQ) responses, acoustic rhinometry, peak flow readings, and endoscopic scoring of nasal polyps were recorded prior to desensitization and after 6 months of maintenance therapy.ResultsTwelve patients were recruited for participation and underwent desensitization. Eight patients continued maintenance therapy and follow up at 6 months. Prior to desensitization, patients reported bothersome sinonasal symptoms with a median SNOT-22 score of 30.0 ± 34.5 (interquartile range (IQR)). There was significant improvement after 6 months of maintenance therapy to a median SNOT-22 score of 18.5 ± 17.3 (p = 0.025, Wilcoxon signed rank test). Acoustic rhinometry, endoscopic scores, ACQ and forced expiratory volume values remained stable at 6 months.ConclusionsAERD patients may benefit from ASA desensitization with subjective sinonasal symptom improvement at 6 months and stable asthma and objective sinonasal measures. Further discussion is needed in the otolaryngology community regarding ASA desensitization in AERD management. 相似文献

OBJECTIVES/HYPOTHESIS: The aim of this randomized, partly blinded, controlled clinical trial was to evaluate the effects of debridement 6 and 12 days after endoscopic sinus surgery. METHODS: Sixty patients (male/female = 26/34; mean age, 43.5 years; age range, 23-73 years) with chronic or acute recurrent rhinosinusitis were included. The patients were randomized to postoperative debridement or not. Primary outcome variables were adhesions between the middle turbinate and the lateral nasal wall 10 to 14 weeks after surgery judged by blinded evaluation of endoscopic video recordings. Secondary outcome variables were crusts in the nasal cavity 12 days after surgery and pain caused by debridement. RESULTS: We found a significant reduction in adhesions in the group that underwent debridement (P < .001). At 12 weeks, bilateral adhesions were observed in nine control patients but in only one debridement patient. Unilateral adhesions were found in 11 control patients and in nine debridement patients. Twelve days after surgery, we found significantly less severe crusts in the debridement group (P < .01). Patients with severe crusts in the middle meatus 12 days after surgery had more adhesions 12 weeks postoperatively. The debridement group used more analgesics the days after the first debridement (3.7 days [standard deviation 2.3] vs. 2.3 days [standard deviation 2.6] in the control group, P < .041). CONCLUSIONS: Crusts in the middle meatus after sinus surgery is associated with postoperative adhesions. Debridement of the nasal cavity reduces crusts and postoperative adhesions significantly compared with saline irrigation only. However, the procedure induces more postoperative nasal pain. 相似文献
