The prevalence of Eustachian tube dysfunction symptoms in patients with chronic rhinosinusitis

Background

While Eustachian tube dysfunction (ETD) is a known comorbidity of chronic rhinosinusitis (CRS), the prevalence of ETD symptoms in the CRS population is poorly understood. We sought to determine the cross‐sectional prevalence of ETD in patients with CRS using the validated Eustachian Tube Dysfunction Questionnaire (ETDQ‐7) and to correlate ETDQ‐7 scores with 22‐item Sino‐Nasal Outcome Test (SNOT‐22) scores, endoscopy scores, and computed tomography (CT) scores.

Methods

A total of 101 patients with confirmed CRS completed the ETDQ‐7 and SNOT‐22 at their initial visit to our rhinology clinic. Lund‐Mackay CT and Lund‐Kennedy endoscopy scores were also obtained. Spearman's correlation coefficient (ρ) was calculated.

Results

Among the 101 patients, 49 patients (48.5%) had an ETDQ‐7 score of ≥14.5, signifying clinically significant ETD. The mean ± standard deviation (SD) ETDQ‐7 score of the entire cohort was 17.8 ± 10.1. There was a moderately strong correlation between ETDQ‐7 and the SNOT‐22 ear subdomain (ρ = 0.691, p < 0.001). The correlation coefficient between ETDQ‐7 and total SNOT‐22 scores was ρ = 0.491 (p < 0.001), indicating moderate correlation. ETDQ‐7 scores were poorly correlated to objective measures of sinonasal disease, including Lund‐Mackay CT score (ρ = ?0.055, p = 0.594) and Lund‐Kennedy endoscopy score (ρ = ?0.099, p = 0.334).

Conclusion

Symptoms of ETD are highly prevalent among patients with CRS as documented by patient‐reported outcome measures. The correlation between ETDQ‐7 scores and SNOT‐22 ear subdomain scores is moderately strong, while the correlation between ETDQ‐7 scores and SNOT‐22 scores is moderate. ETD severity does not correlate with CT score or nasal endoscopy score.

     

没食子酸与环丙沙星联用对小鼠慢性鼻-鼻窦炎模型的作用

探讨没食子酸与环丙沙星联用对小鼠慢性鼻-鼻窦炎模型(CRS)的作用。收集难治性CRS患者鼻黏膜样本,分离铜绿假单胞杆菌(Pseudomonas aeruginosa)构建小鼠CRS模型,没食子酸(GA)与环丙沙星(CIP)单独或联合灌胃治疗,HE染色观察小鼠鼻黏膜病理变化,ELISA检测血清炎性因子TNF-α、IL-6、IL-8的表达、试剂盒检测SOD活性、MDA及ROS含量,Western blot检测鼻黏膜组织中TNF-α、IL-6、IL-8、IκB及NF-κB p65的表达。结果显示,GA与CIP可显著降低CRS小鼠TNF-α、IL-6、IL-8、MDA、ROS及NF-κB p65的含量,增加SOD活性及IκB的表达,且联合用药效果更显著。结果说明,GA与CIP联用治疗CRS效果优于单独用药,可能通过抑制NF-κB信号通路,下调TNF-α、IL-6、IL-8表达发挥作用。
