Abstract
PURPOSE Aspirin-exacerbated respiratory disease (AERD) is a severe form of chronic rhinosinusitis with nasal polyps (CRSwNP) accompanied by asthma and an aspirin intolerance. The underlying pathomechanism of AERD still remains unclear, recent data suggest a complex inflammatory imbalance. In the present study, we investigated the cytokine patterns in AERD, CRSwNP and healthy control patients. Furthermore, we describe the change in cytokine level in the course of aspirin desensitization (AD) with continuous intake of aspirin. METHODS The study included a total of 104 participants, 48 healthy controls, 45 patients with nasal polyps and 11 patients with AERD undergoing AD. Nasal secretions were analyzed for IL-1β, IL-4, IL-5, IL-10, IL-12, IL-13, IL-17, THF-α, IFN-γ, eotaxin and ECP using Bio-Plex Human Cytokine Assay and Uni-CAP FEIA. Baseline measurements of cytokine levels were performed in all 104 patients; in patients with AERD, follow-up was performed 1-6 and 6-24 months after the initiation of AD. RESULTS Our preliminary results show a TH2 dominated, eosinophilic milieu in AERD patients, which decreased in the first weeks of AD. However, after 6 months of AD, proinflammatory cytokines show a tendency to increase again. Also, TH1 as well as Treg associated cytokine seem to increase over time. CONCLUSIONS For the first time, the present work shows the cytokine pattern in nasal secretions of AERD patients before and during AD. Further investigation of the complex interaction of inflammatory cytokines during AD might reveal important insights into the disease entity of AERD and open up new horizons for a targeted therapy.

Abstract
Allergic rhinitis (AR), nasal polyps (NP) as well as chronic rhinosinusitis (CRS) are all known to be associated with eosinophilic infiltration and elevated numbers of mast cells (MC) within the mucosa. Both cell types and their markers eosinophilic cationic protein (ECP) and tryptase are utilized in the diagnosis and management of chronic sino-nasal diseases. Mucosal cytology samples were gathered by cytobrush, histological samples were obtained from the inferior turbinate. In both sample sets, the number of eosinophils and MC was determined. Their corresponding markers ECP and tryptase were quantified from nasal discharge. Patients were grouped with reference to their main diagnosis: AR (n = 34), NP (n = 25), CRS (n = 27) and controls (n = 34). Eosinophil counts from cytobrush and ECP levels were significantly elevated in NP compared to all other groups-31- and 13-fold over control, respectively. However, histologic review did not reveal any difference in eosinophil count among groups. Tryptase was significantly elevated threefold in AR versus CRS and controls. No correlation to cytological and histological MC counts could be found. ECP levels in nasal discharge as well as eosinophil counts can provide useful information with regard to the diagnosis. Likewise, tryptase concentrations can do. The presented data show that the measurement of markers in nasal discharge is superior in differentiating among diagnosis groups. Given that the collection of nasal secretions is more comfortable for patients than the more invasive techniques, we recommend first line ECP and tryptase testing performed on nasal secretions.

Abstract
BACKGROUND Patients with nonallergic rhinitis with eosinophilia syndrome (NARES) show typical symptoms of persistent allergic rhinitis (PAR). The aim of the present study was to compare nasal cytokine patterns between NARES and PAR. METHODS Nasal secretions of 31 patients suffering from NARES, 20 patients with PAR to house dust mite and 21 healthy controls were collected using the cotton wool method and analyzed for interleukin (IL)-1β, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12, IL-13, IL-17, granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte colony-stimulating factor (G-CSF), interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), monocyte chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein-1β (MIP-1β) by Bio-Plex Cytokine Assay as well as eosinophil cationic protein (ECP) and tryptase by UniCAP-FEIA. RESULTS NARES and PAR presented elevated levels of tryptase, while ECP was markedly increased solely in NARES compared to both the controls and PAR. Elevated levels of IL-1β, IL-17, IFN-γ, TNF-α and MCP-1 were found in NARES compared to the controls as well as PAR. MIP-1β was elevated in NARES and PAR, while IL-4, IL-6 and G-CSF showed increased levels in NARES, and IL- 5 was elevated in PAR only. CONCLUSIONS In patients with NARES and PAR, eosinophils and mast cells appear to be the pivotal cells of inflammation, reflected by high levels of tryptase and ECP as well as IL-5 and GM-CSF as factors for eosinophil migration and survival. The elevated levels of proinflammatory cytokines in NARES may indicate the chronic, self-perpetuating process of inflammation in NARES which seems to be more pronounced than in PAR. IL-17 might be a factor for neutrophilic infiltration or be responsible for remodeling processes in NARES.

Abstract
The growing popularity and frequency of consumption of seafood is accompanied by an increasing number of adverse reactions reported in literature. Allergic reactions to seafood can generate a variety of symptoms ranging from a mild oral allergy syndrome to keen anaphylactic reactions. Tropomyosin, the major shellfish allergen is regarded to be responsible for clinical cross-reactivity to inhaled house dust mites. The aim of the study was to investigate the prevalence of sensitization to tropomyosin in house dust mite allergic patients in southern Bavaria and to compare the results with allergic symptoms. Sera of house dust mite allergic patients (positive skin prick test, allergen-specific IgE and intranasal provocation) were screened for IgE antibodies to tropomyosin (Der p 10). Patients were contacted by phone to evaluate allergic symptoms when consuming seafood. IgE antibodies to house dust mite tropomyosin (Der p 10) could be found in 4 out of 93 sera (4.3%). Two of these four patients (50%) showed itching and swelling of oral mucosa accompanied by bronchial obstruction after consumption of shrimp. Two patients had no problems when eating seafood. None of the seronegative patients complained about any health problems during or after consumption of seafood. In conclusion, cross-reactivity to tropomyosin in house dust mite allergic patients in southern Bavaria, Germany is rarer than suspected. Beside the direct allergic reactions, a further part of reactions to seafood must therefore be ascribed to other mechanisms such as intoxication or intolerance to, e.g. additives in the food product.

Abstract
Intermittent allergic rhinitis and common cold constitute frequent conditions and show similar clinical symptoms. The purpose of this study was to investigate the pattern of cytokines in the nasal fluid of patients with acute symptoms caused by allergic and viral rhinitis. Nasal secretions were analyzed by immunosorbent assay techniques using a cytokine panel assay and routine ELISA. Allergic patients had significantly higher levels of eosinophil cationic protein (ECP), interleukin (IL)-5, and tryptase. Significantly elevated concentrations of proinflammatory cytokines (IL-1b, IL-6, IL-7, IL-17, interferon [IFN] gamma, and tumor necrosis factor [TNF]-alpha) as well as chemokines for cellular infiltration (IL-8, monocyte chemoattractant protein 1, and macrophage inflammatory protein 1beta), factors for cellular proliferation (granulocyte colony-stimulating factor [G-CSF] and granulocyte macrophage colony-stimulating factor [GM-CSF]), and elastase were found in viral rhinitis. IL-10 was only detectable in viral rhinitis. IL-4 was significantly higher in patients with viral rhinitis than allergic rhinitis, and IL-5 was significantly elevated in viral rhinitis compared with controls. In viral-triggered rhinitis, we detected a predominantly Th1-type cytokine pattern with potent proinflammatory mediators. Factors reflecting a neutrophil and eosinophil immune response, due to IL-5, IL-8, GM-CSF, ECP, and elastase were shown. Nasal secretions of patients with allergic rhinitis showed highest concentrations of tryptase, IL-5, and ECP, reflecting a mast cell and eosinophil immune response. Nasal secretion levels of IL-4 did not show highest levels in allergic rhinitis but did in viral rhinitis. IL-4 also may play a role in limiting inflammatory processes by inhibiting the production of inflammatory cytokines.

Abstract
A total of 206 patients of the otorhinolaryngology (ORL) department and 204 of the visceral surgery department of the Ludwig Maximilians University of Munich were preoperatively evaluated for latex-specific sensitization. A prick test, a questionnaire, and an enzyme-linked immunosorbent assay immunoprecipitation for IgE antibodies were performed. Latex is a widely spread allergen, and it does not only concern healthcare populations. Within the ORL surgery group, 43 (20.9%) patients were sensitized against latex allergen, and 2 of them were reported to manifest symptoms in consorting with latex. In the cohort of visceral surgery patients, we detected only 23 patients (11.3%) with sensitization against latex. Moreover, most patients were positively detected with the skin prick test (86.4%), whereas the enzyme-linked immunosorbent assay method was less sensitive (18.3%). Patients of the ORL department were considerably more frequently exposed to latex protein particles than patients of the visceral surgery department. This difference attributes to their significant difference in mean age: 44 years in the ORL patients group versus 58 years in the visceral patients cohort. Furthermore, we did not find any correlation to the number of past operations--although undergoing any surgical procedures is a well-known risk factor in other studies about latex sensitization in surgical patients.

Abstract
OBJECTIVE This study focused on factors contributing to eosinophilia after intranasal allergen challenge. METHODS Nasal secretions of 13 allergic individuals were gained over a period of 8 hours after nasal allergen challenge. Early and late phase reactions were determined by acoustic rhinometry and changes of volume and total protein in nasal secretions. Eosinophilia was demonstrated by nasal eosinophilic cationic protein. Interleukin (IL)-5; the chemokines IL-8, monocyte chemotactic protein (MCP)-1 and MCP-3, and eotaxin; soluble vascular cell adhesion molecule 1 (sVCAM-1); and the leukotriene C4 (LTC4) were analyzed by enzyme-linked immunosorbent assay for their suggested impacts on tissue eosinophilia. RESULTS By means of rhinometry, we observed in 69% an alternating type of late phase response, followed by a bilateral (15%) or unilateral (8%) type. A biphasic kinetic could be demonstrated by changes in nasal volume and total protein of nasal secretions, reflecting the early and late phase responses. A typical late phase kinetic was observed for IL-5, MCP-1, eotaxin, sVCAM-1, and LTC4. Interleukin 8 was characteristic for early phase reaction but increased in late phase as well. We could not detect any MCP-3 in our samples. CONCLUSIONS Our data point to a relevant role of the T(H)2 cytokine IL-5; of the chemokines IL-8, MCP-1, and eotaxin; of the adhesion molecule sVCAM-1; and of the leukotriene LTC4 for the allergic late phase eosinophilia.

Abstract
BACKGROUND This examination focused on the allergic early and late phase reaction via nasal symptom scores, acoustic rhinometry, and the determination of mediators possibly involved in late phase eosinophilia. We examined nasal secretions for IL-5; the chemokines IL-8, MCP-1, and Eotaxin; the adhesion molecule sVCAM-1, and the leukotriene LTC4 for their suggested impacts on tissue eosinophilia. METHODS 13 patients suffering from seasonal allergic rhinitis were challenged intranasally out of the natural pollen season by their specific allergen. In a time window of 8 h following the provocation, patients completed symptom questionnaires, and underwent acoustic rhinometry. Nasal secretions were gained by the cotton wool method over a time period of 8 h. Nasal secretions were analyzed for the above mentioned mediators. RESULTS Individual evaluation of the acoustic rhinometry measurements revealed an early phase reaction in 100 % of the cases and a late phase reaction in 92 %. The need to sneeze and a runny nose were the strongest symptoms during the allergic early and late phase reaction. A typical late phase kinetic was observed for IL-5, MCP-1, Eotaxin, sVCAM-1, and LTC4. IL-8 was characteristic for early phase reaction but increased in late phase as well. CONCLUSIONS The need to sneeze, a runny nose, and the overall quality of life were most apt to evaluate the allergic early and late phase reaction. Highly significant correlations between nasal obstruction and acoustic rhinometry measurements indicate a high sensitivity of visual analogue scales in the representation of minimal changes in nasal symptom scores during the allergic reaction. Our data point to a relevant role of the TH2 cytokine IL-5; of the chemokines IL-8, MCP-1, and Eotaxin; of the adhesion molecule sVCAM-1, and of the leukotriene LTC4 for the allergic late phase eosinophilia.

Abstract
BACKGROUND Mucosa-immunologic aspects are gaining an increasing awareness in the pathophysiology of type I allergies. Humoral mucosal immune responses are dominated by secretory IgA, but there is evidence for a relevant role of IgG in nasal mucosa-associated lymphoid tissue. OBJECTIVE was to measure allergen-specific immunoglobulins (IgA and IgG) in nasal secretions as an expression of a humoral mucosal immune response in allergic rhinitis. For tissue eosinophilia we studied nasal Eosinophilic Cationic Protein (ECP) and for mast cell activation nasal tryptase. METHODS Nasal secretions of 40 patients suffering from allergic rhinitis were analyzed for allergen-specific IgA, IgG, and IgE, and for ECP and tryptase. Patients were highly sensitized against the major allergens of house dust mites, timothy, and birch pollen. 43 non-atopic individuals served as controls. In order to study possible effects of the actual pollen season on the studied parameter we secondly compared patients allergic to seasonal allergens co- (n = 28) and extra-seasonally (n = 41). In order to determine a possible influence of allergen-specific IgA in eosinophilic degranulation we additionally studied 5 patients after nasal allergen challenge. RESULTS In allergic rhinitis we found significantly increased levels of allergen-specific immunoglobulins of all studied subclasses and allergens in nasal secretions. Comparison of nasal ECP and tryptase showed significantly increased concentrations in allergic individuals as well. Co-seasonally we found elevated allergen-specific IgE, ECP, and tryptase but lower concentrations of allergen-specific IgA and IgG. There was no association between late phase eosinophilia and IgA concentrations after local allergen challenge. CONCLUSIONS The occurrence of allergen-specific immunoglobulins in nasal secretions is interpreted as a local humoral mucosal immune response. The physiologic role of local allergen-specific immunoglobulins is not clear to date. Involvement in degranulation of eosinophils or mast cells, like suggested before, seems unlikely.

Abstract
This examination is an approach of the allergic early phase reaction (EPR) and late-phase reaction (LPR) via quality of life (QoL), acoustic rhinometry, and eosinophilic cationic protein (ECP), interleukin (IL)-5, and leukotriene C4 (LTC4). Results are discussed under consideration of a possible neurological participation in the occurrence and persistence of the allergic inflammatory process. Thirteen patients suffering from seasonal allergic rhinitis were challenged intranasally by their specific allergen. In a time window of 8 hours after provocation, patients completed QoL questionnaires, and underwent acoustic rhinometry. Nasal secretions were analyzed for total protein, ECP, IL-5, and LTC4 The need to sneeze and a runny nose were the strongest symptoms during the EPR and LPR. Restriction of overall QoL persisted much longer than any other symptom. Evaluation of acoustic rhinometry revealed an EPR in 100% and a LPR in 92%. The EPR was marked by increases in volume of nasal secretions, total protein, and elevations in LTC4. Allergic LPR was marked by increases in nasal secretions, total protein, ECP, IL-5, and LTC4. Both the need to sneeze as strongest and announcing symptom of the allergic LPR and the persisting restriction in overall QoL seem to propose a possible neurological participation in the development of the allergic late-phase inflammation and consequent hyperresponsiveness of the nasal mucosa. In addition, the persistence and enhancement of the nasal cycle during the allergic LPR can be interpreted in favor of a hypothetical activation of the autonomous nervous system. LTC4 enters this discussion as a promising link at the immunoneurological interface.

Abstract
BACKGROUND Differential diagnosis of chronic nasal inflammation is insufficient when based solely on clinical examination and radiography of paranasal sinuses. Patients complain about more or less similar symptoms. Activation of mast cells and eosinophils is pivotal in nasal inflammation. OBJECTIVE To compare tryptase and eosinophilic cationic protein (ECP) in nasal secretions in different forms of chronic nasal inflammation and to establish norm values. METHODS The study included 1710 patients presenting with nasal complaints. Nasal secretions were gained by the cotton wool method and analysed for tryptase, as a marker of mast cell activation, and for ECP, as a marker of tissue eosinophilia and activation. Patients were grouped according to their diagnosis: chronic, non-allergic rhinosinusitis (sinusitis, n=194), non-allergic nasal polyposis (polyposis, n=138), non-allergic rhinitis with eosinophilia syndrome (NARES, n=198), isolated perennial allergic rhinitis (AR) (n=126), isolated seasonal AR (n=132), and patients allergic to both, seasonal and perennial allergens (n=193). Seven hundred and twenty-nine patients with nasal complaints due to a deviated septum and without any nasal inflammation served as controls. RESULTS Nasal tryptase was highly significantly (P<0.001) elevated in polyposis, NARES, and in AR. ECP was highly significantly (P<0.001) elevated in all groups of patients suffering from chronic nasal inflammation. Based on our data and method we established norm values (95% confidence interval of mean value) for nasal tryptase in healthy adults, ranging from 12.0 to 18.7 ng/mL and for ECP ranging from 84.4 to 102.6 ng/mL. CONCLUSION Mast cells and eosinophils are involved in non-allergic and allergic forms of chronic nasal inflammation. We established an in vitro assay for tryptase and ECP in nasal secretions and defined norm values based on our data and method. In vitro measurement of biological markers in nasal secretions provides important information for differential diagnosis and therapeutic strategies of chronic nasal inflammation.

Abstract
Obstructive sleep apnea syndrome (OSAS) is a condition characterized by recurrent episodes of obstruction of the upper airway. The aim of this study was to evaluate whether nasal obstruction due to allergic rhinitis constitutes a risk factor for OSAS. Patients (n = 119) presenting typical symptoms of sleep apnea were tested for OSAS using polysomnography. Additionally all patients were tested in vivo and in vitro (including nasal eosinophilic cationic protein) for allergic rhinitis. Examination for allergic rhinitis revealed that 88.3% of all patients had no allergic rhinitis, whereas only 11.7% were diagnosed as allergic. No significant differences in sleeping parameters were observed between allergic and non-allergic patients. Comparison of parameters indicative of relevant OSAS (apnea-hypopnea index [AHI] > 10) revealed that 60% of non-allergic patients had relevant OSAS, compared to only 50% of allergic patients. Investigation of allergic subgroups revealed similar results: no significant differences in sleeping parameters or elevated rates of relevant OSAS parameters were observed, especially in perennial allergic rhinitis due to house dust mites. No elevated rates of allergic rhinitis were observed in the studied cohort of patients suffering from sleep apnea or OSAS. Furthermore, no significant differences in sleeping behavior or polysomnography parameters were found on comparing allergic and non-allergic patients. In summary, our data rule out allergic rhinitis as a major risk factor for OSAS.

Abstract
Late-phase response in allergic rhinitis is characterized by tissue eosinophilia and influx of CD4+ T-cells. IL-16 and MIP-1 alpha are highly chemotactic on T-cells and on eosinophils. Both IL-16 and MIP-1 alpha have been demonstrated to be up-regulated after challenge in the late-phase response in various atopic conditions other than allergic rhinitis. The aim of our study was to determine the expression of IL-16 and MIP-1 alpha in nasal secretions following allergen challenge in allergic rhinitis, and to compare these with characteristic late-phase mediators such as IL-5 and ECP. Nasal secretions of 14 allergic volunteers challenged intranasally by their specific allergen were studied from 20 minutes to 8 hours after allergen challenge. Nasal secretions were analyzed by routine ELISA for IL-16, MIP-1 alpha, IL-5, and ECP. IL-16 and MIP-1 alpha increased significantly in nasal secretions of challenged allergic patients in the late-phase response. IL-16 revealed highest amounts 5 hours after challenge, whereas MIP-1 alpha peaked at 7 hours. Both correlated significantly (r = 0.917, p < 0.05) at 6 hours. IL-5 and ECP peaked between 6 and 8 hours and correlated significantly (r = 0.951, p < 0.01) at 6 hours as well. Our data demonstrate that IL-16 and MIP-1 alpha are expressed in the late-phase response in allergic rhinitis in a more or less similar kinetic like IL-5 and ECP. They are suggested to be responsible for the observed influx of eosinophils (IL-5, IL-16, and MIP-1 alpha) and CD4+ T-cells (IL-16 and MIP-1 alpha) into the challenged allergic mucosa.

Abstract
OBJECTIVE To compare concentrations of interleukin-5 (IL-5), immunoglobulin E (IgE), eosinophilic cationic protein (ECP), and soluble intercellular adhesion molecule-1 (sICAM-1) in nasal secretion and serum of patients with chronic nonallergic sinusitis, allergic rhinitis, and nonallergic nasal polyposis to obtain information about the pathogenesis of these diseases. METHODS Nasal secretion and serum were analyzed by routine enzyme-linked immunosorbent assay techniques. Nineteen patients with chronic nonallergic sinusitis, 24 patients with seasonal allergic rhinitis, and 18 patients with nonallergic nasal polyposis were included in the study. Eight healthy, nonallergic probands served as control subjects. RESULTS Significantly elevated concentrations of IL-5 (5-fold, P < .05) and IgE (15-fold, P < .01) were detected in nasal secretion of patients with allergic rhinitis (IL-5, 51.8 +/- 13.2 pg/mL; IgE, 41.9 +/- 20.9 kU/L) or nonallergic nasal polyposis (IL-5, 57.9 +/- 36.9 pg(mL; IgE, 40.5 +/- 20.2 kU/L) compared with controls (IL-5, 10.6 +/- 7.8 pg/mL; IgE, 2.8 +/- 0.5 kU/L) or with patients with chronic nonallergic sinusitis (IL-5, 16.5 +/- 13.2 pg/mL; IgE, 5.4 +/- 3.1 kU/L). There were no significant differences between patients with allergic rhinitis and those with nonallergic nasal polyposis. Concentrations of ECP were significantly elevated (sixfold, P < .01) in patients with allergic rhinitis (297.8 ng/mL +/- 173.1) compared with controls (52.4 +/- 28.0 ng/mL) or patients with chronic nonallergic sinusitis (44.8 +/- 40.1 ng/mL), whereas twofold higher concentrations (not significant) of ECP were observed in patients with nonallergic nasal polyposis (107.1 +/- 26.6 ng/mL). Significantly elevated concentrations of sICAM-1 in nasal secretion (threefold, P < .05) were detected only in patients with chronic nonallergic sinusitis (79.4 +/- 45.6 ng/mL). The elevated sICAM-1 nasal secretion values in this group correlated significantly (P < .05) to the serum values. CONCLUSIONS Equally elevated concentrations of IL-5 and IgE in patients with allergic rhinitis and nonallergic nasal polyposis implicated similar pathogenic processes in both diseases. Whereas the pathogenesis of allergic rhinitis is IgE-specific, the pathogenesis of nasal polyps is not as clear. IL-5 was suggested to play a pivotal role in tissue eosinophilia, which was confirmed by data in the present study. Elevated concentrations of ECP were suggested to result from tissue eosinophilia--a characteristic of both diseases. Elevated concentrations of sICAM-1 in patients with chronic nonallergic sinusitis pointed to its key role in the recruitment of neutrophils into the inflamed tissue, whereas an important role in eosinophil recruitment was ruled out.
