Objectives Our intention was to review all material published to date regarding superantigens (SAgs) and allergy from an otorhinolaryngological viewpoint to understand this association more clearly. Methods We identified all materials published mentioning both SAg and allergic rhinitis (AR), chronic sinusitis, asthma, and atopic dermatitis (AD) that are indexed on PubMed, Google, or the ProQuest Central databases. Results Staphylococcus aureus is a significant bacterial pathogen in humans and has the ability to produce enterotoxins with superantigenic features. The inflammatory response in allergy seen in both B cell and T cell may be attributed to SAgs. Sufferers of both allergic asthma with rhinitis and AR alone produce serological evidence of immunoglobulin E formation to SAgs produced by S. aureus. Perennial AR sufferers carry S. aureus more frequently and the presence of the organism within the nasal cavity may exacerbate perennial AR. SAg produced by S. aureus potentially worsens the asthmatic inflammatory response within the airway and may lead to the airways becoming hyperresponsive, as well as possibly activating T cells if asthmatic control is poor. Staphylococcal SAgs potentially increase the risk of developing chronic rhinosinusitis with nasal polyposis, additionally being a marker for more severe disease. If SAgs bring about chronic inflammatory responses in the nose and sinuses, then T cells excreting interferon-gamma may be a crucial mediator. In allergic dermatitis, S. aureus could be a key player in exacerbation of the condition. Even in younger pediatric patients with allergic dermatitis, allergic hypersensitivity to SAgs is frequent and may be a factor explaining how severe the condition becomes. Conclusion Just as SAgs are known to feature in many allergic conditions, they play their part in AR, chronic rhinosinusitis, asthma, and AD. Further research is required before the relationship between SAgs and allergy can be adequately explained.

Chronic rhinosinusitis with nasal polyps is a multifactorial disease of the nasal and paranasal sinus mucosa and it includes, as comorbidities, anatomic and morphologic alterations, allergic rhinitis, and immunologic diseases. We investigated matrix metalloproteinases (MMP-2, MMP-7, and MMP-9) and their tissue inhibitors (TIMP-1 and TIMP-2) concentration in different etiopathogenetical groups of patients with nasal polyposis (NP) in relation to recurrence after sinonasal surgery. The study group consisted of 45 patients with NP (those with allergic rhinitis, nonallergic rhinitis and asthma or nonallergic rhinitis, and obstruction of osteomeatal complex [OMC]) who underwent endonasal sinus surgery. We also collected 10 patients who underwent septoplasty as control. Immunohistochemistry of nasal mucosa fragments, Western blotting, and polymerase chain reaction analysis showed increased MMPs levels (MMP-9 more than MMP-2 and MMP-7) and decreased tissue inhibitors of MMPs levels (TIMP-1 less than TIMP-2), in patients with chronic rhinosinusitis with nasal polyps compared with control group, in particular in patients with nonallergic rhinitis and asthma compared to those with allergic rhinitis and nonallergic rhinitis and obstruction of OMC. We observed a higher risk of recurrence in patients with nonallergic rhinitis and asthma than in those with allergic rhinitis and nonallergic rhinitis and obstruction of OMC after 36 months from surgery. In this research, we evaluated pathogenesis of NP related to MMPs and their inhibitors concentrations in polypoid tissue.

Chronic rhinosinusitis (CRS) with and without nasal polyps represent different stages of one chronic inflammatory disease of the mucosa of the nasal cavity and paranasal sinuses. Coexistence of chronic rhinosinusitis with nasal polyps and asthma and rather similar characteristics of inflammation support assumption that chronic rhinosinusitis and nasal polyps and asthma may be, at least in part, the same disease process. We therefore aimed to evaluate the differences of sinus radiologic findings, systemic inflammation and allergy markers, pulmonary function of chronic rhinosinusitis associated with nasal polyps and asthma. A total of 121 patients with chronic rhinosinusitis referred to tertiary center were evaluated; 23 healthy persons served as controls. Sinus CT scans and nasal endoscopy were performed. Allergic rhinitis was diagnosed according to history and positive skin prick tests to common inhalant allergens. Asthma was diagnosed according to GINA by history and pulmonary function tests. Aspirin intolerance was assessed by history. Total IgE, Aspergillus fumigatus-specific IgE levels, leukocyte and eosinophil count in the peripheral blood were measured. Nasal polyps were detected in 84 patients (69.4%), asthma diagnosed in 48 patients (39.6%), associated with nasal polyps (91.7%) and allergic rhinitis in 45.5% of patients. Forty-four patients with chronic rhinosinusitis and having nasal polyps and asthma were characterized by older age (P<0.01), greater duration of nasal symptoms (P<0.001), higher number previous surgeries (P<0.01), more severe sinus disease on CT scan (P<0.001), greater blood leukocyte and eosinophil count, total IgE level (P<0.01), bronchial obstruction (P<0.05), incidence of allergic rhinitis (P<0.01), and sensitivity to house dust mite D. pteronyssinus (47.7%, P<0.01) and mold allergens (29.5%, P<0.01) comparing to the patients with isolated chronic rhinosinusitis. The extent of sinus CT changes was greater in asthmatics and correlated with greater duration of asthma (P<0.0001), higher number of previous surgeries (P=0.001), leukocyte count in blood (P=0.025), and age (P=0.039). Conclusion. Our data indicate that patients with chronic rhinosinusitis compose clinically heterogeneous group and when associated with nasal polyps and asthma constitutes the most severe form of unified respiratory tract disease, which is characterized by older age of the patients, greater duration of nasal symptoms, extent of sinus radiological changes, more prominent systemic inflammation markers, greater bronchial obstruction, incidence of perennial allergic rhinitis
