Computational Modeling of Nasal Drug Delivery Using Different Intranasal Corticosteroid Sprays for the Treatment of Eustachian Tube Dysfunction.

Eustachian tube dysfunction (ETD) is a common otolaryngologic condition associated with decreased quality of life. The first-line treatment of ETD is intranasal corticosteroid sprays (INCS). Computational fluid dynamics (CFD) was used to study particle deposition on the Eustachian tube (ET) using two commercial INCS (Flonase and Sensimist). Simulations also considered the effects of nostril side, insertion depth, insertion angle, cone spray angle, inhaling rates, wall impingement treatment, and fluid film. Flonase and Sensimist produced different particle size distributions and sizes. Sensimist droplets are smaller, less sensitive to asymmetry in nostrils anatomy and variation in insertion angle, and therefore can reach the posterior nasopharynx more readily. Flonase produces larger particles with greater inertia. Its particles deposition is more sensitive to intrasubject variation in nasal anatomy and insertion angles. The particle deposition on the ET was sensitive to the wall impingement model. The deposition on the ET was insignificant with adherence only <0.15% but increased up to 1-4% when including additional outcomes rebound and splash effects when droplets impact with the wall. The dose redistribution with the fluid film is significant but plays a secondary effect on the ET deposition. Flonase aligned parallel with the hard palate produced 4% deposition efficiency on the ET, but this decreased <0.14% at the higher insertion angle. INCS with larger droplet sizes with a small insertion angle may be more effective at targeting droplet deposition on the ET opening.

Chronic Rhinosinusitis Outcomes of Patients With Aspirin-Exacerbated Respiratory Disease Treated With Budesonide Irrigations: A Case Series.

BACKGROUND: Pathophysiology-targeting treatments exist for aspirin-exacerbated respiratory disease (AERD) through aspirin desensitization and biologics, such as dupilumab. With increasing attention paid to these treatments, which may be associated with significant side effects and/or cost, there is little description of chronic rhinosinusitis with nasal polyps (CRSwNP) response to treatment with intranasal corticosteroids and saline irrigations in AERD. OBJECTIVE: To determine the effect of intranasal budesonide irrigations for the treatment of CRSwNP in AERD. METHODS: This is an observational study of 14 AERD patients presenting to a rhinology clinic for CRS who were treated with twice daily high volume, low pressure irrigations with 240 mL of saline to which a 0.5 mg/2 mL respule of budesonide was added. All participants completed a 22-item Sinonasal Outcome Test (SNOT-22) at enrollment and at follow up 1 to 6 months later. Polyp scores were also calculated at each time point. RESULTS: SNOT-22 scores ranged from 26 to 98 (median: 40.5) at enrollment and 3 to 85 (median: 38.5) at follow-up. Polyp scores ranged from 2 to 6 (median: 4) at enrollment at 0 to 6 (median: 2) at follow-up. Over the treatment period, change in SNOT-22 score ranged from -38 to 16 (median: -18) and change in polyp score ranged from -2 to 0 (median: -0.5). Approximately 57% of participants experienced at least 1 minimal clinically important difference in SNOT-22 score and 21% of participants had a SNOT-22 score <20 at follow-up. CONCLUSION: Medical management with intranasal corticosteroids and saline irrigations alone leads to significant improvement in sinonasal symptomatology in a subset of AERD.

Chronic Rhinosinusitis Patients With and Without Polyps Experience Different Symptom Perception and Quality of Life Burdens.

OBJECTIVE: We sought to determine if chronic rhinosinusitis (CRS) patients with nasal polyps (CRSwNP) differentially perceived CRS symptom burden compared to patients without nasal polyps (CRSsNP) and to what extent CRS symptom severity was associated with quality of life (QOL) and patient-reported symptom control in the 2 groups. METHODS: A total of 600 patients (266 CRSwNP and 334 CRSsNP) presenting with CRS were recruited. CRS symptom burden was assessed with the 22-item Sinonasal Outcome Test (SNOT-22). SNOT-22 nasal, sleep, ear/facial discomfort, and emotional subdomain scores were calculated. General health-related QOL was assessed with the visual analog scale of the 5-dimensional EuroQol questionnaire (EQ-5D VAS). Patients rated their CRS symptom control on a 5-point scale. RESULTS: SNOT-22 scores did not differ between CRSwNP (mean: 35.6) and CRSsNP (mean: 36.3). There were no differences in nasal, sleep, and emotional subdomains of the SNOT-22. CRSsNP had higher (P = .003) ear/facial subdomain scores than CRSwNP, while CRSwNP reported greater hyposmia (P < .001). EQ-5D VAS was significantly lower (P = .011) in CRSsNP (mean: 68.9) compared to CRSwNP (mean: 73.2). However, CRSwNP patients reported significantly less symptom control, compared to CRSsNP, in association with nasal and emotional symptoms. CONCLUSION: CRSwNP and CRSsNP have differences in symptom profile, effect on health-related QOL, and patient-perceived symptom control. CRSsNP experience significantly greater burden of ear/facial discomfort, while CRSwNP report greater hyposmia. Although CRSsNP reports lower general health-related QOL overall, CRSwNP patients had lower levels of CRS symptom control for every incremental increase in symptom burden suggesting greater sensitivity/intolerance to CRS symptoms.

Seasonal variations in chronic rhinosinusitis symptom burden may be explained by changes in mood.

PURPOSE: There are many year-round modifiers of chronic rhinosinusitis (CRS). However, it is unknown whether there are seasonal variations in the sinonasal symptom burden of CRS. METHODS: This was a retrospective cross-sectional study of sinonasal symptom burden measured using the 22-item Sinonasal Outcome Test (SNOT-22) and its four associated nasal, sleep, ear/facial discomfort and emotional subdomains in 1028 individuals with CRS. The season (winter, spring, summer or fall) when the SNOT-22 was completed was recorded. Regressions, controlling for clinical and demographic characteristics, were performed to seek association between season of the year and SNOT-22 total and subdomain scores. RESULTS: The mean SNOT-22 scores were 37.4 for those individuals completing their SNOT-22 in the fall, 40.5 in the winter, 37.4 in the spring and 36.0 in the summer. There was a statistically significant association between higher SNOT-22 scores and completing the SNOT-22 in the wintertime (adjusted ß = 4.08, 95% CI 0.74-7.42, p = 0.017). When seeking association between season and SNOT-22 subdomain scores, wintertime was associated only with higher emotional (adjusted ß = 0.48, 95% CI 0.14-0.81, p = 0.006) and sleep (adjusted ß = 2.23, 95% CI 0.54-3.91, p = 0.010) subdomain scores. Examining individual SNOT-22 items, these associations were due to more symptoms related to depressed mood ("sad") and psychomotor retardation. CONCLUSION: There are seasonal variations in symptom burden of CRS patients, independent of aeroallergen hypersensitivity, with the greatest increase in baseline CRS symptomatology during the winter. This finding was most strongly associated with increased emotional symptomatology and depressed mood.
