Nasal polyposis is a common problem in otolaryngology. The cause remains unclear, and treatment with medication and surgery is often unsatisfactory. We present our controlled study, which suggests a strong association between food allergy and nasal polyposis. The study was conducted in 2 parts. A postal survey of 900 patients with nasal polyps showed 53 respondents (5.9%) had a known food allergy. In the prospective study, 80 nasal polyp patients and 36 control subjects completed intra-dermal tests for food allergy. Sixty-five nasal polyp patients (81%) and 4 control subjects (11%) had positive intradermal food test results. This is highly significant. We believe that food allergy may play a significant role in the pathogenesis of nasal polyposis and should be further studied.

Platelet-activating factor (PAF) is known to be an important mediator of anaphylaxis. However, there is a lack of information in the literature about the role of PAF in food allergy. The aim of this work was to elucidate the participation of PAF during food allergy development and the consequent adipose tissue inflammation along with its alterations. Our data demonstrated that, both before oral challenge and after 7 days receiving ovalbumin (OVA) diet, OVA-sensitized mice lacking the PAF receptor (PAFR) showed a decreased level of anti-OVA IgE associated with attenuated allergic markers in comparison to wild type (WT) mice. Moreover, there was less body weight and adipose tissue loss in PAFR-deficient mice. However, some features of inflamed adipose tissue presented by sensitized PAFR-deficient and WT mice after oral challenge were similar, such as a higher rate of rolling leukocytes in this tissue and lower circulating levels of adipokines (resistin and adiponectin) in comparison to nonsensitized mice. Therefore, PAF signaling through PAFR is important for the allergic response to OVA but not for the adipokine alterations caused by this inflammatory process. Our work clarifies some effects of PAF during food allergy along with its role on the metabolic consequences of this inflammatory process.

OBJECTIVE: To measure alterations in SPA1, A2, and D gene expression in various forms of inflammatory chronic rhinosinusitis (CRS). STUDY DESIGN AND SETTING: Sinus mucosal biopsies were performed in patients with allergic fungal rhinosinusitis (AFS), CRS with nasal polyposis, cystic fibrosis (CF), and controls. SP mRNA was measured with quantitative polymerase chain reaction. RESULTS: Patients with CF (n = 4) showed significantly increased SPA1 (82-fold), SPA2 (100-fold), and SPD (47-fold) mRNA ( P < 0.05) when compared with controls (n = 5). Patients with CRS with nasal polyposis (n = 5) also demonstrated elevated SPA1 (27-fold), SPA2 (13-fold), and SPD (13-fold). Patients with AFS (n = 7) had increased SPA1 (5-fold), SPA2 (9-fold), and SPD (17-fold), but were not statistically significant. CONCLUSION: SPA1, A2, and D are upregulated in various forms of CRS, but are significantly elevated in cystic fibrosis CRS. SIGNIFICANCE: Understanding the role of SPs in CRS will help develop novel treatment approaches for sinonasal pathoses.

Background Chronic sinusitis and nasal polyps with subsequent nasal blocking, anosmia, and relapsing infections are frequent in the rhinological practice. Often, recurrent disease necessitates repetitive conservative therapy and surgical treatment (functional endoscopic sinus surgery). This study was initiated to scrutinize the relationship of wheat and milk allergies to chronic polypoid sinusitis (CPS) and recurrent disease. Methods Blood samples of 50 healthy controls and 50 patients with clinically and radiologically diagnosed CPS and nasal polyposis were screened for common food allergies including wheat and milk allergy. On inclusion into the study, none of the patients reported a symptomatic food allergy. Results Fifteen of 100 tested subjects (15%) revealed a previously undiagnosed allergy to inhalant (dust, rye, and pollens) and other food allergens (corn and egg white). Six of 50 patients (12%) with CPS exhibited a wheat allergy, and a milk allergy could be identified in 7 patients (14%). In the control group, seven healthy subjects (14%) showed a wheat allergy and no case of milk allergy could be identified (p = 0.0125). Conclusion In contrast to previous studies in other countries presenting a food allergy incidence of ∼75% in patients with nasal polyposis, we could not show such a high incidence. In the group with chronic polyposis 14% of the patients were positive for milk allergy compared with none of the tested healthy subjects, resulting in a strong statistical significance. Therefore, we conclude that cow's milk but not wheat allergy might be a relevant pathogenetic entity in chronic nasal polyps.
