Objective To evaluate the impact of untreated deviated nasal septum (DNS) on recalcitrant chronic rhinosinusitis (CRS) among patients undergoing revision endoscopic sinus surgery (ESS). Study Design Case-control study. Setting Tertiary academic center. Subjects and Methods We performed a retrospective review of 489 patients undergoing revision ESS for CRS at a tertiary academic center. Patients undergoing septoplasty were matched to nonseptoplasty controls based on age and sex. Preoperative Lund-Mackay score (LMS) was compared between cohorts. Linear regression was used to identify predictors of LMS and ostiomeatal complex (OMC) obstruction. Results Thirty-six matched pairs (72 patients) were selected for analysis: 36 undergoing septoplasty and revision ESS and 36 undergoing revision ESS alone. Compared with nonseptoplasty controls, the septoplasty group had a significantly higher average LMS (17.8 vs 14.6, P = .02) and a greater rate of OMC obstruction (89% vs 61%, P < .01). The septoplasty group also had significantly higher opacification scores in the maxillary (1.5 vs 1.2, P = .03) and posterior ethmoid (1.8 vs 1.4, P = .02) sinuses. On multivariable analysis, DNS was an independent predictor of LMS ( P = .02) and OMC obstruction ( P < .01). Conclusion Untreated DNS is associated with radiographic markers of CRS severity among patients undergoing revision ESS and may contribute to the multifactorial pathogenesis of persistent CRS.

Objective While urinary leukotriene E4 (uLTE4) is a validated biomarker for the cysteinyl leukotriene pathway, which is central to the pathophysiology of asthma, atopy, and chronic rhinosinusitis (CRS), the contributions of comorbid asthma and atopy to uLTE4 levels in various CRS subtypes have not been previously characterized. We sought to (1) identify reference values for uLTE4 in subjects with and without CRS and (2) determine how the presence of comorbid atopy and asthma affects uLTE4 levels in CRS. Setting Tertiary referral medical center. Subjects and Methods A prospective case-control study was conducted to compare uLTE4 levels between patients with CRS and healthy controls. Urinary LTE4 levels were measured by enzyme immunoassay and were adjusted for urinary creatinine concentrations (pg/mg Cr). Patients with CRS were stratified by the clinical comorbidities to determine normative uLTE4 values for patients with CRS with and without comorbid asthma or atopy. Results A total of 153 patients (mean age, 47.3; 47.1% female) were included in the study. Patients with CRS demonstrated significantly higher concentrations of uLTE4 than healthy controls (1652 vs 1065 pg/mg Cr, P = .032). Within the group of patients with CRS, comorbid asthma also individually correlated with elevated uLTE4 levels (1597 pg/mg Cr, P = .0098). Patients with CRS who did not have comorbid allergy and asthma, in contrast, did not have statistically higher uLTE4 levels than healthy controls (1142 pg/mg Cr, P = .61). Conclusion Urinary LTE4 serves as a noninvasive measure of the inflammatory state in CRS. Comorbid asthma and atopy contribute to elevated uLTE4 levels in CRS.

Abstract Evidence shows that chronic rhinosinusitis (CRS) is associated with prior presence of autoimmune diseases; however, large-scale population-based studies in the literature are limited. We conducted a population-based case–control study investigating the association between CRS and premorbid autoimmune diseases by using the National Health Insurance Research Database in Taiwan. The CRS group included adult patients newly diagnosed with CRS between 2001 and 2013. The date of diagnosis was defined as the index date. The comparison group included individuals without CRS, with 1:4 frequency matching for gender, age, and index year. Premorbid diseases were forward traced to 1996. Univariate and multivariate logistic regression was performed to estimate odds ratios (ORs) and 95% confidence intervals. The CRS group consisted of 30,611 patients, and the comparison group consisted of 122,444 individuals. Patients with CRS had a higher significant association with premorbid autoimmune diseases (adjusted OR 1.39 [1.28–1.50]). Specifically, patients with CRS had a higher significant association with ankylosing spondylitis, polymyositis, psoriasis, rheumatoid arthritis, sicca syndrome, and systemic lupus erythematosus (adjusted OR 1.49 [1.34–1.67], 3.47 [1.12–10.8], 1.22 [1.04–1.43], 1.60 [1.31–1.96], 2.10 [1.63–2.72], and 1.69 [1.26–2.25]). In subgroup analysis, CRS with and without nasal polyps demonstrated a significant association with premorbid autoimmune diseases (adjusted OR 1.34 [1.14–1.58] and 1.50 [1.38–1.62]). In addition, CRS with fungal and non-fungal infections also demonstrated a significant association with premorbid autoimmune diseases (adjusted OR 2.02 [1.72–2.49] and 1.39 [1.28–1.51]). In conclusion, a significant association between CRS and premorbid autoimmune diseases has been identified. These underlying mechanisms need further investigation.

Background:Multiple sclerosis (MS) is an autoimmune disease with known genetic and environmental susceptibility factors. Breastfeeding has been shown to be protective in other autoimmune diseases.Objective:This case-control study analyzed the association of breastfeeding in infancy on the risk of developing MS.Methods:A case-control study was performed in Berlin of 245 MS patients and 296 population-based controls, who completed a standardized questionnaire on their history and duration of breastfeeding in infancy and demographic characteristics. Univariable and multivariable logistic regression analysis was performed to investigate the association between breastfeeding and MS. The multivariate model was adjusted for age, gender, number of older siblings, number of inhabitants in place of domicile between ages 0 and 6 (categorized in each case), and daycare attendance between ages 0 and 3.Results:In multivariable analysis, breastfeeding showed an independent association with MS (adjusted OR 0.58; p = 0.028). However, with no breastfeeding as reference, the protective effect only emerges after four months of breastfeeding (multivariable analysis for ≤ four months adjusted OR 0.87; p = 0.614 and for > four months OR 0.51; p = 0.016).Conclusion:The results of this case-control study support the hypothesis that breastfeeding is associated with a lower risk of MS. These results are in line with findings of previous studies on other autoimmune diseases, in which breastfeeding was shown to have protective effects.

Background It has been suggested that chronic rhinosinusitis may lead to epiphora because of inflammatory edema at the nasal end of the nasolacrimal duct and that treatment of the underlying nasal disease may obviate the need for dacryocys-torhinostomy. The aim of this study was to establish whether or not there is an association between the signs and symptoms of chronic rhinosinusitis and a complaint of epiphora in a blinded, prospective case-control study. Methods A consecutive series of 15 adult patients presenting to the ophthalmology department with acquired epiphora were compared with 29 patients presenting with chronic open-angle glaucoma over the same study period. Nasal symptoms and the findings on nasal endoscopy were recorded by a single otolaryngologist blinded to the diagnosis and using a standardized staging system. Results The age and sex distributions of the two groups were similar. Scores for headache and altered smell were significantly higher in the epiphora cases than in controls (p = 0.05 and 0.03, respectively). Trends for higher scores for congestion and discharge were not statistically significant (p = 0.06 and 0.07, respectively). Mucosal edema and discharge were significantly more common on endoscopy in the epiphora cases than in the control cases (p < 0.02). Conclusion We have shown an association between rhinosinusitis and acquired epiphora, and this would be consistent with chronic rhinosinusitis being the cause of the epiphora in some cases.
