Abstract
House dust mite (HDM) is the most significant indoor allergen, responsible for not only many cases of rhinoconjunctivitis but also for many cases of bronchial asthma, rendering it of considerable socioeconomic relevance. Besides symptomatic treatment and avoidance measures, allergen immunotherapy (AIT) is crucial, as the only causal, disease-modifying therapeutic approach. However, high diagnostic certainty is essential for initiating AIT. The challenge in making a correct diagnosis lies in interpreting the demonstrated HDM sensitization regarding its clinical relevance (clinically silent sensitization vs. allergy). While the risk of allergy increases with the level of IgE titers against HDM extract, Der p 1, or Der p 2, as well as with the breadth of the molecular sensitization profile against HDM components (Der p 1, Der p 2, Der p 23), no threshold can be defined for the presence of allergy, nor can sensitization to a specific component be confidently considered allergy inducing. It should be noted that at least in Southern Bavaria, the prevalence of Der p 23 sensitization is too low to be considered a major allergen, and Der p 23 is not able to molecularly differentiate all HDM sensitizations when added to the two major allergens Der p 1 and Der p 2. Evidently, HDM possesses a diverse profile of allergens, with some relevant ones possibly yet to be described. Unfortunately, patient history does not provide a sufficient assessment of the clinical relevance of a demonstrated HDM sensitization, necessitating allergen provocation testing before initiating AIT with HDM, despite the relatively large effort involved.

Abstract
INTRODUCTION Allergic rhinitis is a global health problem that can potentially be managed through acupressure. Our clinical observations have identified Allergic Rhinitis Acupressure Therapeutic (ARAT) as a novel acupressure treatment acting on specific acupoints, which may enhance the effectiveness of acupressure. Therefore, we propose a three-arm randomized controlled trial will be conducted to investigate the efficacy and safety of ARAT for perennial allergic rhinitis (PAR). METHODS/DESIGN In this trial, eligible 111 participants diagnosed with PAR will be randomly assigned to one of three groups: the ARAT group, the non-specific acupoints group, or the blank control group. The primary outcome will be the change in the total nasal symptom score, and the secondary outcomes will include: 1) changes in the scores of the standard version of Rhinoconjunctivitis Quality of Life Questionnaire (RQLQs); 2) acoustic rhinometry and anterior rhinomanometry; 3) changes in the scores of relief medication usage; 4) incidence of adverse events. Additionally, we will measure and compare the changes in cytokine levels (IL-5, IL-13, IFN-γ, and TSLP) in nasal secretions. The RQLQs and primary outcomes will be assessed at the beginning, middle, and end stages of the treatment period, with monthly follow-ups conducted over a total of three months. The secondary outcomes and biomarkers in nasal secretions will be measured at the beginning and end of the treatment period. Any adverse events or need for rescue medication will be carefully noted and recorded. DISCUSSION This study may produce a new acupressure treatment prescription that is easy to learn, more targeted, and adaptable. This trial represents the first clinical investigation comparing ARAT treatment for PAR with the non-specific acupoints group and blank control group. Our data is expected to provide evidence demonstrating the safety and efficacy of ARAT for PAR patients, while also exploring the functional mechanism underlying ARAT treatment, moreover, the results offer valuable insights for healthcare professionals in managing PAR symptoms.

Abstract
INTRODUCTION Skin prick tests (SPTs) are the gold standard for diagnosis of allergic rhinitis (AR). A decrease in the number of allergens included in standard SPT panels has recently been debated - particularly regarding the cross-reacting homologous pollen from birch, alder, and hazel trees - but has not yet been implemented in clinical guidelines. METHODS A subgroup of patients with AR (n = 69) who showed inconsistent SPT results among birch, alder, and hazel was investigated in detail. Beyond SPT, patient workup included assessment of clinical relevance and various serological parameters (total IgE, and specific IgE to birch, alder, and hazel and to Bet v 1, Bet v 2, and Bet v 4). RESULTS More than half the study group had negative SPT results for birch but positive results for alder and/or hazel, and 87% of the study group was polysensitized, showing at least one more positive SPT result for other plants. Whereas 30.4% of patients showed serological sensitization to birch pollen extract, only 18.8% displayed positive specific IgE to Bet v 1. Clinical assessment revealed that most patients with AR were polysensitized and had perennial symptoms or symptoms also occurring during times other than tree flowering times. If the SPT panel is limited to testing birch only, 52.2% of patients in this subgroup would have been overlooked. CONCLUSION Inconsistent SPT results in the birch homologous group may result from cross-reacting allergens or technical errors. If patients report convincing clinical symptoms despite negative results from a reduced SPT panel or inconsistent results for homologous allergens, SPT should be repeated, and molecular markers should be added to achieve a correct diagnosis.

Abstract
BACKGROUND In the 5 years that have passed since the publication of the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (ICAR-Allergic Rhinitis 2018), the literature has expanded substantially. The ICAR-Allergic Rhinitis 2023 update presents 144 individual topics on allergic rhinitis (AR), expanded by over 40 topics from the 2018 document. Originally presented topics from 2018 have also been reviewed and updated. The executive summary highlights key evidence-based findings and recommendation from the full document. METHODS ICAR-Allergic Rhinitis 2023 employed established evidence-based review with recommendation (EBRR) methodology to individually evaluate each topic. Stepwise iterative peer review and consensus was performed for each topic. The final document was then collated and includes the results of this work. RESULTS ICAR-Allergic Rhinitis 2023 includes 10 major content areas and 144 individual topics related to AR. For a substantial proportion of topics included, an aggregate grade of evidence is presented, which is determined by collating the levels of evidence for each available study identified in the literature. For topics in which a diagnostic or therapeutic intervention is considered, a recommendation summary is presented, which considers the aggregate grade of evidence, benefit, harm, and cost. CONCLUSION The ICAR-Allergic Rhinitis 2023 update provides a comprehensive evaluation of AR and the currently available evidence. It is this evidence that contributes to our current knowledge base and recommendations for patient evaluation and treatment.

Abstract
"Nasal hyperreactivity" is a key feature in various phenotypes of upper airway diseases, whereby reactions of the nasal epithelium to diverse chemical and physical stimuli are exacerbated. In this review, we illustrate how nasal hyperreactivity can result from at least three types of mechanisms: (1) impaired barrier function, (2) hypersensitivity to external and endogenous stimuli, and (3) potentiation of efferent systems. We describe the known molecular basis of hyperreactivity related to the functional impairment of epithelial cells and somatosensory innervation, and indicate that the thermal, chemical, and mechanical sensors determining hyperreactivity in humans remain to be identified. We delineate research directions that may provide new insights into nasal hyperreactivity associated with rhinitis/rhinosinusitis pathophysiology and therapeutics. The elucidation of the molecular mechanisms underlying nasal hyperreactivity is essential for the treatment of rhinitis according to the precepts of precision medicine.

Abstract
PURPOSE For perennial inhalant allergens such as house dust mite (HDM), the German guideline on allergen-specific immunotherapy explicitly recommends provocation testing. This procedure is time-consuming, expensive, and potentially dangerous for the patient. Recently it has been discussed whether provocation tests are really necessary for diagnosing allergy to Dermatophagoides species. Thus, our study aimed to analyze the concordance between nasal provocation tests with Dermatophagoides species and anamnestic data. METHODS We retrospectively analyzed the concordance between patients' histories including self-reported symptom scores and the results of provocation testing in 471 individuals with proven sensitization to Dermatophagoides species. RESULTS 248 patients had a positive nasal provocation test (NPT) result to Dermatophagoides species and 223 individuals a negative NPT result. Patients allergic to HSM suffered significantly more often from atopic dermatitis (14% vs. 7%, p = 0.046) and more from asthma (20% vs. 19%, p = 0.851). Moreover, individuals with clinically silent sensitization complained less about nasal secretion (37% vs. 45%, p = 0.244) but significantly more about nasal dryness (46% vs. 34%, p = 0.046) whereas rates of nasal airway obstruction, ocular complaints and sleep quality were comparable in both groups. Allergic patients reported more often perennial (34% vs. 30%, p = 0.374) and location-dependent (39% vs. 31%, p = 0.090) symptoms. However, the discrepant prevalence of atopic dermatitis was the only statistically significant difference between both groups. CONCLUSION Despite slight differences between both patient groups, clinical data are not sufficient to distinguish between silent sensitization and clinically relevant allergic rhinitis to HDM. Therefore, nasal provocation testing remains the gold standard for assessing clinical relevance in patients sensitized to Dermatophagoides species.

Abstract
BACKGROUND Allergen identification is the first step for allergen-specific immunotherapy (AIT) of allergic rhinitis (AR). Currently, the diagnosis of AR is based mainly on the positive results of the skin prick test (SPT) and/or serum specific immunoglobulin E (sIgE) measurement. However, the results of these two tests may not always directly correlate with AR. OBJECTIVE To investigate the importance of nasal provocation testing (NPT) in the diagnosis of Dermatophagoides pteronyssinus (Der p)-induced AR. METHODS Rhinitis patients willing to undergo AIT (n = 171) were enrolled. The correlations of Der p SPT, sIgE, NPT, and clinical symptom severity were assessed. RESULTS NPT-positive responses were more common in patients with higher SPT and sIgE levels. The optimal cut-off value for a NPT-positive response for SPT was 5.5 mm and for sIgE was 2.77 kUA/L, based on the respective receiver operating characteristic (ROC) curves. The area under the curve (AUC) of the ROCs was 0.814 (SPT only) and 0.794 (sIgE only) and increased to 0.828 with the combination of SPT and sIgE. The Der p-NPT concentration was inversely correlated with SPT and sIgE levels (r = -0.477, P < .001, and r = -0.461, P < .001, respectively), but none was correlated with the total nasal symptom score. CONCLUSION For patients who are willing to receive Der p AIT, NPT is a useful and safe test to confirm diagnosis prior to treatment initiation, especially in patients with lower levels of Der p SPT (< 5.5 mm) or sIgE (< 2.77 kUA/L).

Abstract
OBJECTIVES Several allergy tests are used for the diagnosis of allergic rhinitis; however, few studies have reported a direct comparison of the skin prick test (SPT), multiple allergen simultaneous test (MAST), and ImmunoCAP according to specific allergens. This study aimed to evaluate the correlations between each test and allergic rhinitis symptoms and to evaluate the correlations of the MAST and ImmunoCAP with the SPT for representative indoor allergens in Korea. METHODS Electronic medical charts were retrospectively reviewed, and 698 patients with allergic rhinitis who had performed SPT, MAST, and ImmunoCAP were enrolled. Correlations between each allergy test for 4 representative indoor allergens and the symptoms of allergic rhinitis were analyzed. Agreements of the MAST and ImmunoCAP with the SPT were compared according to each allergen. RESULTS The SPT showed higher correlations with allergic rhinitis symptoms for 4 indoor allergens (Dermatophagoides pteronyssinus, Dermatophagoides farinae, cat, and dog allergens) than the MAST or ImmunoCAP. In comparison between the MAST and SPT, the least correlation was observed for the dog allergen, whereas between the ImmunoCAP and SPT, the least correlation was observed for the cat allergen. The correlation between the ImmunoCAP and SPT was higher than that between the MAST and SPT for the dog allergen, whereas no significant differences were noted for other allergens. CONCLUSIONS Overall, the SPT showed a higher correlation with allergic rhinitis symptoms than the MAST or ImmunoCAP for 4 indoor allergens. ImmunoCAP showed similar reactivity to MAST; however, it showed better positivity with dog allergen in patients who were reactive to the allergen in the SPT. Care should be taken while evaluating dog allergen sensitization using the MAST.

Abstract
Occupational rhinitis (OR) has so far received little attention even though it shares common pathophysiological features and trigger factors and is closely associated with occupational asthma (OA). Work-related exposure to certain substances, such as animal dander, is considered to be the main factor for the development of OR. The new EAACI definition of OR stresses the causal relationship between workplace exposure and onset of rhinitis symptoms as opposed to previous definitions that mainly focused on a temporal relationship between workplace exposure and occurrence of nasal symptoms. Also, it has been suggested to use the term “work-related rhinitis” for classifying the different forms of rhinitis associated with the workplace. These forms can be subdivided into allergic or non-allergic OR, which is due to causes and conditions related to a particular work environment, as well as work-exacerbated rhinitis, which is defined as a pre-existing rhinitis exacerbated by exposure at the workplace. Even though taking a detailed patient history is especially important when it comes to diagnosing OR, the gold standard for confirming the diagnosis is nasal provocation testing. Best possible symptomatic relief and prevention of development of OA constitute the main therapeutic objectives in OR. Treatment options consist of total avoidance of trigger substances (main goal), reduction of exposure to certain substances, and pharmacotherapy. Furthermore, it is important to note that allergic OR is an occupational disease in Germany (Berufskrankheit No 4301) and needs to be reported to health authorities.

Abstract
There is convincing evidence that tight relationships between the upper and lower airways also apply to the workplace context. Most patients with occupational asthma (OA) also suffer from occupational rhinitis (OR), although OR is 2 to 3 times more common than OA. OR most often precedes the development of OA, especially when high-molecular-weight protein agents are involved, and longitudinal cohort studies have confirmed that OR is associated with an increased risk for the development of OA. The level of exposure to sensitizing agents at the workplace is the most important determinant for the development of IgE-mediated sensitization and OR. Atopy is a risk factor for the development of IgE-mediated sensitization only to high-molecular-weight agents. In workers with work-related rhinitis symptoms, documentation of IgE-mediated sensitization to a workplace agent via skin prick testing or serum specific IgE confirms a diagnosis of probable OR, whereas specific nasal provocation testing in the laboratory remains the reference method to establish a definite diagnosis of OR. Complete avoidance of exposure to the causal agent is the most effective therapeutic option for controlling work-related nasal symptoms and preventing the development of OA. If complete elimination of exposure is expected to induce meaningful adverse socioeconomic consequences, reduction of exposure can be considered as an alternative approach, but it is important to consider the individual risk factors for the development of OA to implement a more personalized management of OR.

Abstract
Allergic diseases are assuming increasing trend of prevalence worldwide. The diseases confer increasing demand on medical and healthcare facilities. Patients with allergies have poor quality of life and impaired cognition. Adult patients have subpar working efficiency while afflicted children are less effective at school, often have school absenteeism and need more attention of their caregivers. All of them lead to negative socio-economic impact. This narrative review focuses on cockroach allergy including currently recognized cockroach allergens, pathogenic mechanisms of allergy, componentresolved diagnosis and allergen-specific immunotherapy, particularly the component-resolved immunotherapy and the molecular mechanisms that bring about resolution of the chronic airway inflammation.

Abstract
Background IgE sensitization (atopy) to pets is commonly evaluated using pet dander extracts. However, the diagnosis by components seems to be more adequate to evaluate the clinical relevance (allergy) of sIgE sensitization. Objective To study the association between IgE sensitization to pet allergen components and clinical symptoms. Methodology. Dander extracts and sIgE levels to pet components (Can f 1, Can f 2, Can f 3, Can f 5, Fel d 1, Fel 2, and Fel 4) were measured in a rhinitis group (n = 101) and a control group (n = 101) and a control group (. Results Dog (34.6% vs. 23.5%) and cat dander (26.7% vs. 8.8%, p = 0.05) IgE sensitization was frequent among rhinitis and no-rhinitis subjects, and it was similar to dog (29.7% vs. 20.5%) and cat (18.8% vs. 8.8%) components. Polysensitization for dog (3.1, 95% CI: 1.5 to 6.1, p = 0.05) IgE sensitization was frequent among rhinitis and no-rhinitis subjects, and it was similar to dog (29.7% vs. 20.5%) and cat (18.8% vs. 8.8%) components. Polysensitization for dog (3.1, 95% CI: 1.5 to 6.1, p = 0.05) IgE sensitization was frequent among rhinitis and no-rhinitis subjects, and it was similar to dog (29.7% vs. 20.5%) and cat (18.8% vs. 8.8%) components. Polysensitization for dog (3.1, 95% CI: 1.5 to 6.1. Conclusions Sensitization to pet dander extract identifies atopic patients, but its utility to predict clinical relevance is poor. Allergenic components could help to define the clinical relevance of sensitization to furry animals and could reduce the need for provocation test.

Abstract
Purpose It remains unknown whether allergen-specific immunotherapy (AIT) could attenuate airway inflammatory response triggered by allergen exposure. Methods We performed Dermatophagoides pteronyssinus (Der-p) nasal provocation tests (NPTs) in allergic rhinitis (AR) and/or asthma patients without AIT (non-AIT), or at 16, 52, 104, or 156 weeks after Der-p AIT. Rhinitis and asthma visual analog scale (VAS; VAS of nasal symptoms [VAS-NS], VAS of asthma symptoms), the rhinoconjunctivitis quality of life questionnaire (RQLQ), nasal lavage, sputum induction, fractional exhaled nitric oxide (FeNO), nasal airway resistance, pulmonary function, and airway hyperresponsiveness were performed before and after NPT. Results Non-AIT subjects demonstrated significantly higher VAS-NS before and after NPT compared to AIT subjects (P < 0.05). NPT response was positive in 14 (100%) non-AIT, 7 (70%) 16 weeks-AIT, 6 (60%) 52 weeks-AIT, 6 (60%) 104 weeks-AIT, and 2 (20%) 156 weeks-AIT subjects. The NPT grade significantly correlated with AIT duration and baseline RQLQ score (r = −0.561, P < 0.001 and r = 0.525, P < 0.001, respectively). Sputum and nasal lavage eosinophil count, and FeNO in non-AIT subjects were significantly increased 6 hours after NPT (P < 0.05). AIT subjects did not change their sputum or nasal lavage eosinophil count before and after NPT. Subjects with 156 weeks-AIT demonstrated significantly lower levels of sputum and nasal lavage eosinophil count before and after NPT when compared with non-AIT patients (P < 0.05). Sputum eosinophil counts positively correlated with nasal lavage eosinophil counts at baseline and 6 hours after NPT (r = 0.719, P = 0.006 and r = 0.823, P < 0.001, respectively) in non-AIT patients. Conclusion Our results show that AIT can attenuate both upper and lower airway immune response to nasal allergen exposure in patients with AR and/or asthma.

Abstract
Background Allergic rhinitis is characterized by nasal inflammation in response to allergen exposure. Nasal allergen challenges are used in clinical trials evaluating drug effects. Reproducibility of nasal secretion cytokine responses and physiological measurements are needed to determine the optimum measurements and power calculations for future studies. We have investigated the reproducibility of nasal cytokine measurements, using ready-to-use polyvinyl acetate sponges to collect nasal secretions, and measurements of nasal physiological responses. Methods Twelve subjects with allergic rhinitis and no history of respiratory disease, and 12 subjects with asthma and allergic rhinitis underwent a nasal allergen challenge. This was repeated at 7-14 days later. Results There were increases in IL-5, CCL11, and CXCL8 responses post-challenge (all P<0.05). There was better reproducibility at later time points when higher cytokine levels were detected for IL-5 (ri =0.64 at 8 hours) and CXCL8 (ri =0.91 at 8 hours). Acoustic rhinometry provided good to excellent reproducibility (ri =0.66-0.89). Rhinomanometry had lower reproducibility with greater variation (ri =0.10-0.70), with some subjects unable to perform the measurement. Multiplex immunoassays provided greater sensitivity for CCL11 measurements. There were no differences between allergic rhinitis patients with and without asthma. Conclusion Polyvinyl acetate sponges are a practical and reproducible way to sample nasal secretions. Acoustic rhinometry is a practical and reproducible method for assessing physiological responses. There were no differences in nasal response due to the presence of concurrent asthma.

Abstract
INTRODUCTION Although the skin prick test (SPT) is a reliable diagnostic tool in perennial allergic rhinitis (PER) for patients allergic to cats, the minimum necessary SPT wheal size required to distinguish cat sensitization from true allergy remains controversial. The cat nasal challenge test (cNCT) could be considered the gold standard for detecting true cat allergy. AIMS To assess the difference in the frequency of cNCT positivity between cat owners and non-owners and to determine an appropriate cut-off level for SPT wheal size in detecting positive cNCT in PER patients who are candidates for allergen immunotherapy (AIT) with cat allergen extracts. SUBJECTS AND METHODS cNCT in the form of a nasal spray was administered to 60 adult patients with PER, i.e., cat owners (n = 19) and cat non-owners (n = 41) with positive SPT to cat fur allergen (Diater, Spain). Subjective (total nasal symptom score [TNSS]) and objective measurements (peak nasal inspiratory flow [PNIF]) for assessment of nasal patency and nasal eosinophil count [NEo]) were used to assess the nasal response. Peak expiratory flow (PEF) was used as a safety parameter during cNCT. RESULTS No differences were obtained in SPT wheal size and cNCT positivity between cat owners and non-owners. Positive cNCT detecting true cat allergy could be predicted by a cat SPT wheal size > 6.5 mm with 71.11% sensitivity and 100% specificity. CONCLUSIONS In adult patients with PER, the frequency of cat allergy was similar among cat owners and non-owners. A cat SPT wheal size ≥6.5 mm could be helpful in detecting true cat allergy by avoiding the demanding, time-consuming, and often unavailable cNCT when cat AIT is needed.

Abstract
BACKGROUND Chronic rhinitis (CR) is currently regarded as a syndrome, which presents as several endotypes. The aim of this study was to identify the CR endotype clusters and investigate the inflammatory patterns associated with the different endotypes. METHODS A total of 259 CR patients and 20 control subjects were enrolled in this prospective study. Twelve clinical variables were analyzed using cluster analysis and five inflammatory variables were measured to investigate the inflammatory patterns associated with the different clusters. RESULTS Six endotype clusters of CR were defined in the Chinese CR patients. Patients in cluster 1 (38.6%) were diagnosed as allergic rhinitis (AR) without asthma, and in cluster 2 (13.5%) as AR with asthma, with all demonstrating positive results for local eosinophils and high levels of local and serum IgE. Similarly, patients in cluster 3 (18.6%) were diagnosed as nonallergic rhinitis with eosinophilia syndrome (NARES) without asthma and in cluster 5 (5.0%) as NARES with asthma, with all demonstrating positive results for local eosinophils, and negative results for both local and serum IgE. Patients in cluster 4 (4.6%) were diagnosed as local allergic rhinitis and showed positive results for local eosinophils and local IgE, but negative results for serum IgE, whereas patients in cluster 6 (19.7%) were diagnosed as idiopathic rhinitis because of high symptoms scores, but negative findings for local eosinophils, local IgE, and serum IgE. CONCLUSIONS Chinese CR patients may be clustered into six endotypes with different inflammatory patterns, which may help in delivering individualized treatment.

Abstract
We describe four cases of slaughterhouse workers with occupational immediate allergy to raw pork allergens, confirmed by positive skin prick testing and specific immunoglobulin E (IgE) antibodies. Our first patient was diagnosed with occupational asthma from raw pork allergens. Two patients were diagnosed with occupational rhinitis caused by raw pork allergens, which was confirmed by a nasal provocation test. One of these also had occupational contact urticaria caused by raw pork meat. We were unable to diagnose an occupational respiratory or skin disease in the fourth patient, despite signs of immediate sensitization to raw pork meat from occupational exposure. Based on proper diagnoses, measures to prevent allergen exposure were taken, which led to the improvement of symptoms in these four patients. The present patient cases highlight the importance of recognition of early signs of occupational allergy and identification of causative allergens in order to allow avoidance of allergens, with the aim of preventing persistence and worsening of symptoms.

Abstract
Rhinitis and asthma are common diseases that are strongly linked from both the epidemiological and patho-physiological point of view. A precise aetiological diagnosis is required in order to optimize treatment. Nasal provocation tests (NPT) determine precisely the role of the allergen in the initiation of the symptoms of rhinitis particularly when the history does not produce convincing evidence of the clinical relevance of an allergen. It may also have important consequences for the choice of an allergenic immunotherapy. NPT are not standardized but simple methods based on international recommendations provide us with good diagnostic accuracy. In this paper, we will discuss the practical aspects of NPT as well as the clinical or research situations where they may be useful for the respiratory physician.

Abstract
Nasal allergen challenge (NAC) is an important tool to diagnose allergic rhinitis. In daily clinical routine, experimentally, or when measuring therapeutic success clinically, nasal allergen challenge is fundamental. It is further one of the key diagnostic tools when initiating specific allergen immunotherapy. So far, national recommendations offered guidance on its execution; however, international divergence left many questions unanswered. These differences in the literature caused EAACI to initiate a task force to answer unmet needs and find a consensus in executing nasal allergen challenge. On the basis of a systematic review containing nasal allergen challenges of the past years, task force members reviewed evidence, discussed open issues, and studied variations of several subjective and objective assessment parameters to propose a standardized way of a nasal allergen challenge procedure in clinical practice. Besides an update on indications, contraindications, and preparations for the test procedure, main recommendations are a bilaterally challenge with standardized allergens, with a spray device offering 0.1 mL per nostril. A systematic catalogue for positivity criteria is given for the variety of established subjective and objective assessment methods as well as a schedule for the challenge procedure. The task force recommends a unified protocol for NAC for daily clinical practice, aiming at eliminating the previous difficulty of comparing NAC results due to unmet needs.

Abstract
Background The results of skin and blood allergen testing are not consistently relevant to clinical manifestations in allergic patients. Objective The aim of the study was to investigate the relationship between severity of allergic rhinitis and different allergen diagnostic tests in Dermatophagoides species-sensitized patients. Methods Study subjects included 65 rhinitis patients-50 with Dermatophagoides pteronyssinus (DP) sensitization (DP+) and 15 without DP sensitization (DP-), and 15 DP+ and 37 DP- healthy controls (HCs) confirmed by allergen skin prick (SPT) and blood specific immunoglobulin E (sIgE) tests. The Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) was tested. All subjects underwent DP nasal provocation test (DP-NPT). Visual analogue scoring (VAS) of nasal symptoms and nasal airway resistance (NAR) were measured before and after NPT. Correlations between the 3 allergen tests and score of RQLQ were performed. Results All rhinitis subjects had significantly higher VAS and NAR after DP-NPT than HCs ( P < .01). All DP+ rhinitis, 40% of DP- rhinitis subjects, 13.3% of DP+ HCs and 0% of DP- HCs had positive DP-NPT. Dose of positive DP-NPT positively correlated with SPT diameter and sIgE level in all tested subjects ( P < .001). Score of RQLQ positively correlated with dose of DP-NPT ( P < .001), but not with SPT diameter and sIgE level in rhinitis patients. Conclusion Although DP nasal provocation, skin prick wheal size and blood sIgE level correlate with each other, only nasal provocation testing is associated with severity of nasal symptoms. It is suggested that NPT should be performed to verify a clinically relevant allergy.

Abstract
BACKGROUND Critical examination of the quality and validity of available allergic rhinitis (AR) literature is necessary to improve understanding and to appropriately translate this knowledge to clinical care of the AR patient. To evaluate the existing AR literature, international multidisciplinary experts with an interest in AR have produced the International Consensus statement on Allergy and Rhinology: Allergic Rhinitis (ICAR:AR). METHODS Using previously described methodology, specific topics were developed relating to AR. Each topic was assigned a literature review, evidence-based review (EBR), or evidence-based review with recommendations (EBRR) format as dictated by available evidence and purpose within the ICAR:AR document. Following iterative reviews of each topic, the ICAR:AR document was synthesized and reviewed by all authors for consensus. RESULTS The ICAR:AR document addresses over 100 individual topics related to AR, including diagnosis, pathophysiology, epidemiology, disease burden, risk factors for the development of AR, allergy testing modalities, treatment, and other conditions/comorbidities associated with AR. CONCLUSION This critical review of the AR literature has identified several strengths; providers can be confident that treatment decisions are supported by rigorous studies. However, there are also substantial gaps in the AR literature. These knowledge gaps should be viewed as opportunities for improvement, as often the things that we teach and the medicine that we practice are not based on the best quality evidence. This document aims to highlight the strengths and weaknesses of the AR literature to identify areas for future AR research and improved understanding.

Abstract
INTRODUCTION The guidelines on allergic rhinitis aim to update knowledge about the disease and care for affected patients. The initiative called "Allergic Rhinitis and its Impact on Asthma", initially published in 2001 and updated in 2008 and 2010, has been very successful in disseminating information and evidence, as well as providing a classification of severity and proposing a systemized treatment protocol. In order to include the participation of other medical professionals in the treatment of allergic rhinitis, it is important to develop algorithms that accurately indicate what should and can be done regionally. OBJECTIVE To update the III Brazilian Consensus on Rhinitis - 2012, with the creation of an algorithm for allergic rhinitis management. METHODS We invited 24 experts nominated by the Brazilian Association of Allergy and Immunology, Brazilian Association of Otorhinolaryngology and Head and Neck Surgery and Brazilian Society of Pediatrics to update the 2012 document. RESULTS The update of the last Brazilian Consensus on Rhinitis incorporated and adapted the relevant information published in all "Allergic Rhinitis and its Impact on Asthma" Initiative documents to the Brazilian scenario, bringing new concepts such as local allergic rhinitis, new drugs and treatment evaluation methods. CONCLUSION A flowchart for allergic rhinitis treatment has been proposed.

Abstract
BACKGROUND Allergic reactions to the common house plant Hoya compacta (HC) have not previously been described. AIMS To confirm HC as the cause of rhinoconjunctivitis in three horticultural workers. METHODS Greenhouse working conditions were reproduced in our challenge chamber. RESULTS All three cases developed rhinoconjunctivitis when working with HC plants. A control challenge was performed in two cases with iceberg lettuce causing no symptoms. Nasal volume measured by acoustic rhinometry (AR) fell after all three active challenges, but also after one of the control challenges. CONCLUSIONS Our study confirms that HC may cause occupational rhinoconjunctivitis and asthma through a Type I hypersensitivity reaction. Specific inhalation challenges, nasal nitric oxide measurement and AR may be useful additional tools in supporting such diagnoses for occupational physicians to consider.

Abstract
BACKGROUND The diagnosis of allergic rhinitis (AR) is based on cutaneous and serological assessment to determine immunoglobulin E (IgE)-mediated disease. However, discrepancies between these tests and nasal provocation exist. Patients diagnosed as non-allergic rhinitis (NAR) but with positive nasal allergen provocation test (NAPT) may represent a local allergic condition or entopy, still suitable to allergy interventions. The objective of this study was to determine the frequency of nasal reactivity toward allergens among AR and NAR patients, and to describe the diagnostic characteristics of NAPT methodologies. METHODS EMBASE (1947-) and Medline (1946-) were searched until December 8, 2015. A search strategy was used to identify studies on AR or NAR patients subjected to diagnostic local nasal provocation. All studies providing original NAPT data among the AR or NAR population were included. Meta-analysis of proportion data was presented as a weighted probability % (95% confidence interval [CI]). RESULTS The search yielded 4504 studies and 46 were included. The probability of nasal allergen reactivity for the AR population was 86.3% (95% CI, 84.4 to 88.1) and in NAR was 24.7% (95% CI, 22.3 to 27.2). Reactivity was high with pollen for both AR 97.1% (95% CI, 94.2 to 99.2) and NAR 47.5% (95% CI, 34.8 to 60.4), and lowest with dust for both AR 79.1% (95% CI, 76.4 to 81.6) and NAR 12.2% (95% CI, 9.9 to 14.7). NAPT yielded high positivity when defined by subjective end-points: AR 91.0% (95% CI, 86.6 to 94.8) and NAR 30.2% (95% CI, 22.9 to 37.9); and lower with objective end-points: AR 80.8% (95% CI, 76.8 to 84.5) and NAR 14.1% (95% CI, 11.2 to 17.2). CONCLUSION Local allergen reactivity is demonstrated in 26.5% of patients previously considered non-allergic. Similarly, AR, when defined by skin-prick test (SPT) or serum specific IgE (sIgE), may lead to 13.7% of patients with inaccurate allergen sensitization or non-allergic etiologies.

Abstract
This article is an abridged version of the AWMF mould guideline "Medical clinical diagnostics of indoor mould exposure" presented in April 2016 by the German Society of Hygiene, Environmental Medicine and Preventive Medicine (Gesellschaft für Hygiene, Umweltmedizin und Präventivmedizin, GHUP), in collaboration with the above-mentioned scientific medical societies, German and Austrian societies, medical associations and experts. Indoor mould growth is a potential health risk, even if a quantitative and/or causal relationship between the occurrence of individual mould species and health problems has yet to be established. Apart from allergic bronchopulmonary aspergillosis (ABPA) and mould-caused mycoses, only sufficient evidence for an association between moisture/mould damage and the following health effects has been established: allergic respiratory disease, asthma (manifestation, progression and exacerbation), allergic rhinitis, hypersensitivity pneumonitis (extrinsic allergic alveolitis), and increased likelihood of respiratory infections/bronchitis. In this context the sensitizing potential of moulds is obviously low compared to other environmental allergens. Recent studies show a comparatively low sensitizing prevalence of 3-10% in the general population across Europe. Limited or suspected evidence for an association exist with respect to mucous membrane irritation and atopic eczema (manifestation, progression and exacerbation). Inadequate or insufficient evidence for an association exist for chronic obstructive pulmonary disease, acute idiopathic pulmonary hemorrhage in children, rheumatism/arthritis, sarcoidosis and cancer. The risk of infection posed by moulds regularly occurring indoors is low for healthy persons; most species are in risk group 1 and a few in risk group 2 (Aspergillus fumigatus, A. flavus) of the German Biological Agents Act (Biostoffverordnung). Only moulds that are potentially able to form toxins can be triggers of toxic reactions. Whether or not toxin formation occurs in individual cases is determined by environmental and growth conditions, above all the substrate. In the case of indoor moisture/mould damage, everyone can be affected by odour effects and/or mood disorders. However, this is not a health hazard. Predisposing factors for odour effects can include genetic and hormonal influences, imprinting, context and adaptation effects. Predisposing factors for mood disorders may include environmental concerns, anxiety, condition, and attribution, as well as various diseases. Risk groups to be protected particularly with regard to an infection risk are persons on immunosuppression according to the classification of the German Commission for Hospital Hygiene and Infection Prevention (Kommission für Krankenhaushygiene und Infektionsprävention, KRINKO) at the Robert Koch- Institute (RKI) and persons with cystic fibrosis (mucoviscidosis); with regard to an allergic risk, persons with cystic fibrosis (mucoviscidosis) and patients with bronchial asthma should be protected. The rational diagnostics include the medical history, physical examination, and conventional allergy diagnostics including provocation tests if necessary; sometimes cellular test systems are indicated. In the case of mould infections the reader is referred to the AWMF guideline "Diagnosis and Therapy of Invasive Aspergillus Infections". With regard to mycotoxins, there are currently no useful and validated test procedures for clinical diagnostics. From a preventive medicine standpoint it is important that indoor mould infestation in relevant dimension cannot be tolerated for precautionary reasons. With regard to evaluating the extent of damage and selecting a remedial procedure, the reader is referred to the revised version of the mould guideline issued by the German Federal Environment Agency (Umweltbundesamt, UBA).

Abstract
Background Currently, the diagnosis of allergic rhinitis (AR) is arrived at predominantly by a clinical history and by systemic sensitization tests, but specific nasal provocation tests (NPT) may establish a better direct correlation between etiologic surveyed allergens and nasal symptoms. Objectives To standardize the specific NPT with one of the most important house-dust mites, Dermatophagoides pteronyssinus, monitored by acoustic rhinometry, in children and adolescents, and propose a simplified specific NPT to improve its clinical applicability as a diagnostic tool. Methods Sixteen controls (group 1) and 17 patients with an AR diagnosis sensitized to D. pteronyssinus (group 2) underwent a specific NPT with D. pteronyssinus. The acoustic rhinometry was performed after instillation of 0.15 mL of increasing concentrations of D. pteronyssinus (5000 BU/mL). The test was finalized after (1) instillation of the final concentration of D. pteronyssinus, or (2) after a 20% or more reduction in the volume of the first 5 cm of the nasal cavity (V5), or (3) a score of >3 in the symptoms questionnaire (a score from 0 to 7). A simplified specific NPT with two concentrations was proposed and implemented in a group of 10 patients with AR (group 3). Results At the end of the specific NPT, the median (range) variation in V5 was -5.7% (-9 to 4%) in the control group and -22.8% (-24 to -20%) in group 2. None of the patients in the control group and 88% of group 2 (15/17) showed positive specific NPT results. The simplified specific NPT triggered a positive response in 80% of patients in group 3, with median (range) V5 variation of -30.4% (-36 to -20%). Conclusion This protocol has been proven safe and useful to differentiate between children and adolescents with AR and controls. Concentrations of 1:1000 and 1:100 D. pteronyssinus were the best for use in simplified specific NPT, which made it simpler and faster, and expanded its clinical applicability.

Abstract
Objectives We evaluated the clinical usefulness of Allerkin (Lofarma) for nasal provocation testing (NPT) in patients with rhinitis symptoms, by examining changes in nasal symptoms and acoustic parameters after exposure to house dust mite (HDM) extract. Methods Twenty patients (16 males and 4 females, mean age: 29.6±14.6 years) were enrolled. We performed skin prick test (SPT) before and 15 and 30 minutes after intranasal challenge with Allerkin HDM extract, and we evaluated symptom changes (nasal obstruction, rhinorrhea, sneezing, and itching) using a visual analogue scale. We also evaluated changes in acoustic parameters such as total nasal volume (TNV) and minimal cross-sectional area (MCA) before and after challenge. Results Group A (the nonallergic group, n=8) showed negative results for all tested aeroallergens in SPT and nonprovocative results (<25% decrease of TNV and MCA from the baseline value) in NPT. Group B (the allergic group, n=7) exhibited strongly positive results (wheal size larger than that of histamine) for HDM allergens on SPT. Group C (the local allergic group, n=5) showed negative results on SPT, but a provocative response on NPT (>29% decrease in TNV/MCA from the baseline value). Patients in group C showed significant aggravation of nasal obstruction compared to those in group A (P<0.05). Thirty minutes after HDM challenge, patients in groups B and C showed significantly greater decreases in MCA compared to those in group A (P<0.01). Conclusion Allerkin HDM extract can be a useful provocative agent in NPT for diagnosing allergic rhinitis and local allergic rhinitis.

Abstract
BACKGROUND Allergen-specific immunotherapy for house-dust mite (HDM) allergies is associated with lower success rates when compared with similar treatments for other inhalant allergens, such as grass or birch. One reason might be the greater difficulty in diagnosing patients with assumed HDM allergies because symptoms occur perennially and may differ from those of a conventional allergic rhinitis. OBJECTIVE The aim of the study was to compare the different methods of diagnosis in patients with assumed HDM allergy. METHODS We performed a retrospective analysis of nasal provocation tests (NPT) from patients (n = 161) evaluated for Dermatophagoides pteronyssinus (n = 127) and Dermatophagoides farinae (n = 104) allergies, and compared the results with other allergen testing methods (skin-prick test [SPT], intracutaneous test, and allergen specific immunoglobulin E levels [sIgE] to detect sensitization). Receiver operating characteristic curves were used for the analyses and the areas under the curve were calculated. RESULTS For D. pteronyssinus and D. farinae, 86 and 70 complete data files, respectively, were available. For both tested HDMs, the results of the receiver operating characteristic curves showed a significant correlation for SPT and sIgE, with the results of the NPT (area under the curve, 0.742 to 0.763) but not for the intracutaneous test. In patients with a positive SPT (≥3 mm), an allergy was confirmed by the NPT in 69% of cases for D. pteronyssinus and 71% for D. farinae. A positive sIgE result (ImmunoCAP class of ≥2) was verified by the NPT in 69% of cases (D. pteronyssinus) and 70% (D. farinae). CONCLUSION The predictability value for a positive NPT result is best for SPT and sIgE. Nevertheless, even if the results of both test systems are combined, the positive predictive value that was achieved was only 0.77 for D. pteronyssinus and 0.69 for D. farinae. Therefore, in patients eligible for immunotherapy for HDM, an NPT should be performed before the start of the therapy to verify a clinically relevant allergy.

Abstract
BACKGROUND The most emblematic members of Urticaceae at allergic risk level are wall pellitories (Parietaria), whereas nettle (Urtica) pollen is considered as poorly allergenic. No allergen from nettle pollen has yet been characterized, whereas 4 are listed for Parietaria pollen by the International Union of Immunological Societies. Clinical and biological profiles of 2 adult men who developed symptoms against nettle pollen and/or leaves were studied. OBJECTIVE To characterize the allergic reaction and identify the potential nettle pollen sensitizing allergens. METHODS IgE-mediated reaction to nettle pollen extract was evaluated by skin prick test, immunoassay, nasal provocation, and basophil activation test. To characterize specific nettle pollen allergens, an allergomic (IgE immunoproteomic) analysis was performed combining 1- and 2-dimensional electrophoresis, IgE immunoblots of nettle pollen extract, identification of allergens by mass spectrometry, and database queries. RESULTS The results of biological and immunochemical analyses revealed that the allergic rhinitis was due to Urtica dioica pollen in both patients. The allergomic analysis of nettle pollen extract allowed the characterization of 4 basic protein allergens: a thaumatin-like protein (osmotin) with a relative molecular mass of 27 to 29 kDa, a pectinesterase (relative molecular mass, 40 kDa), and 2 other basic proteins with relative molecular masses of 14 to 16 kDa and 43 kDa. There is no or only very weak allergen associations between pellitory and nettle pollen. CONCLUSION Exposure to nettle pollen can be responsible of allergic symptoms, and several allergens were characterized. Unravelling the allergens of this underestimated allergy might help to improve diagnosis and care for patients, to predict cross-reactivities and design adapted specific immunotherapy.

Abstract
One of the major concerns in the practice of allergy is related to the safety of procedures for the diagnosis and treatment of allergic disease. Management (diagnosis and treatment) of hypersensitivity disorders involves often intentional exposure to potentially allergenic substances (during skin testing), deliberate induction in the office of allergic symptoms to offending compounds (provocation tests) or intentional application of potentially dangerous substances (allergy vaccine) to sensitized patients. These situations may be associated with a significant risk of unwanted, excessive or even dangerous reactions, which in many instances cannot be completely avoided. However, adverse reactions can be minimized or even avoided if a physician is fully aware of potential risk and is prepared to appropriately handle the situation. Information on the risk of diagnostic and therapeutic procedures in allergic diseases has been accumulated in the medical literature for decades; however, except for allergen specific immunotherapy, it has never been presented in a systematic fashion. Up to now no single document addressed the risk of the most commonly used medical procedures in the allergy office nor attempted to present general requirements necessary to assure the safety of these procedures. Following review of available literature a group of allergy experts within the World Allergy Organization (WAO), representing various continents and areas of allergy expertise, presents this report on risk associated with diagnostic and therapeutic procedures in allergology and proposes a consensus on safety requirements for performing procedures in allergy offices. Optimal safety measures including appropriate location, type and required time of supervision, availability of safety equipment, access to specialized emergency services, etc. for various procedures have been recommended. This document should be useful for allergists with already established practices and experience as well as to other specialists taking care of patients with allergies.

Abstract
BACKGROUND No standard study protocol or diagnostic criteria based on nasal provocation test (NPT) and acoustic rhinometry (AR) results are available for allergic rhinitis. OBJECTIVE We aimed to evaluate the usefulness of NPT plus AR for the differential diagnosis of local allergic rhinitis (LAR), allergic, and nonallergic rhinitis. METHODS The medical records and skin-prick test (SPT) and NPT results of 262 patients with symptoms of chronic rhinitis were reviewed. Patients were allocated to one of three groups, that is, group A [n = 110, negative SPT result for Dermatophagoides pteronyssinus (DP)], group B (n = 53, weakly positive result), or group C (n = 99, strongly positive result). RESULTS Twelve patients had a negative SPT result and provoked response in NPT [≥29% decrease of minimal cross-sectional area (MCA) after DP challenge] were diagnosed to have LAR. After DP challenge, group C showed significant aggravation of nasal symptoms and a greater decrease in acoustic parameters than groups A and B (p < 0.01). In patients with a more than or equal to 2 visual analog scale (VAS) increase in nasal obstruction (NO) after DP challenge, the criterion "a change of total nasal symptom score (TNSS) of more than or equal to 6.5" had 90.6% sensitivity and 77.4% specificity for the diagnosis of allergic rhinitis, whereas the diagnostic criterion "a total nasal volume (TNV) change at 30 minutes after DP challenge of more than or equal to 27.6%" had 73.4% sensitivity and 58.1% specificity. CONCLUSION NPT with AR could be a useful tool for the differential diagnosis of allergic, nonallergic, and local allergic rhinitis.

Abstract
BACKGROUND House dust mites are the most prevalent allergen causing sensitizations in patients with rhinitis and asthma in China. We aimed to investigate the changes in both upper and lower airway inflammation and responsiveness following Dermatophagoides pteronyssinus (Der-p) nasal provocation test (NPT) in rhinitis patients. METHODS Study subjects included 15 nonasthmatic Der-p-sensitized rhinitis (AR) patients with airway hyper-responsiveness (AHR) (AR+AHR+), 15 AR patients without AHR (AR+AHR-), 15 healthy controls (HCs) with Der-p sensitization (HC+DP+), and 15 HC without Der-p sensitization (HC+DP-). All subjects underwent Der-p NPT. Visual analogue scale (VAS) scores of nasal symptoms, nasal lavage and nasal airway resistance (NAR) measurement, sputum induction, and forced expiratory volume in 1 second (FEV1 ) were performed. Airway responsiveness to histamine bronchoprovocation (PD20 -FEV1 ) and exhaled nitric oxide (FeNO) was determined. RESULTS NAR increased significantly in all subjects with the greatest effect seen in AR+AHR+ individuals. VAS increased in all subjects at 30 min and returned to baseline at 6 h, with significantly higher levels in AR+AHR+ and AR+AHR- subjects (P < 0.05). Eosinophils in nasal lavage fluid and sputum increased significantly after NPT in AR+AHR+ and AR+AHR- subjects (P < 0.001). FEV1 % and PD20 -FEV1 decreased and FeNO increased significantly after NPT only in AR+AHR+ subjects (P < 0.05). Nasal lavage eosinophil count was positively correlated with sputum eosinophil count and the level of FeNO and negatively correlated with FEV1 and PD20 . CONCLUSIONS House dust mite nasal provocation test induces and aggravates both upper and lower airway inflammation and hyper-responsiveness in patients with persistent allergic rhinitis without asthmatic symptoms.

Abstract
Objective measures can be used to assist the clinician to diagnose and treat nasal obstruction and also to quantify nasal obstruction in research. Objective measurements of nasal obstruction are as important as objective measurements of lung function. peak nasal inspiratory flow (PNIF), acoustic rhinometry (AR) and rhinomanometry (RM), with their specific peculiarity, assess different aspects of nasal obstruction. From the studies available in the literature, it seems that these methods roughly correlate with each other and that all of them can be alternatively utilized very well in research as well as in clinical practice. This review describes the various methods that can be used to measure nasal patency, airflow and resistance, mainly peak nasal inspiratory flow, rhinomanometry and acoustic rhinometry. PNIF has been demonstrated to be reproducible and as good an indication of objective nasal patency as formal rhinomanometry and has the advantage to be cheap, simple and suitable for serial measurements and for home use even in the paediatric population. PNIF normative data are available for children, adults and elderly subjects, and the availability of unilateral PNIF normal values allows evaluation of nasal sides separately. Just as in the lower airways, objective and subjective evaluation gives different information that together optimizes the diagnosis and the treatment of our patients. We argue that PNIF should be used regularly in every outpatient clinic that treats patients with nasal obstruction.

Abstract
<b><i>Background:</i></b> It is important to understand that allergic rhinitis, whether seasonal or perennial, may be difficult to distinguish clinically from the nonallergic forms of rhinitis. <b><i>Objective:</i></b> This study aimed to investigate the presence of local allergic rhinitis (LAR) in children who have allergic rhinitis symptoms in the absence of skin test positivity and specific IgE by performing a nasal provocation test (NPT). <b><i>Methods:</i></b> Our study followed a case-controlled, prospective design. Twenty-eight patients and 30 healthy children were included in the study in a pollen-free season. The NPTs with a grass mix, <i>Dermatophagoides pteronyssinus</i> (DP) and <i>D. farinae</i> (DF) allergens were performed with an interval of 1 week. The total symptom score and visual analog scale, nasal eosinophilia and pulmonary function tests were evaluated before and after each NPT. The change to nasal flow and resistance was recorded by anterior rhinomanometry. <b><i>Results:</i></b> The symptom frequencies before the NPTs were as follows: nasal congestion 100%; itching 82.1%; rhinorrhea 75% and sneezing 71.4%. The NPT was positive in 7 (25%) patients. In the NPT-positive group there was a statistically significant decrease in nasal flow at the concentrations of 10 and 100 IR/ml for DF (p = 0.026, p = 0.031, respectively). In the NPT-positive group total nasal resistance for DP was increased at the concentrations of 0.1 and 10 IR/ml, and for DF at 10 and 100 IR/ml (p = 0.049, p = 0.041, p = 0.022, p = 0.035, respectively). <b><i>Conclusions:</i></b> We emphasize that the diagnosis of LAR should be taken into consideration by pediatricians and pediatric allergy specialists.

Abstract
BACKGROUND Diagnosing house dust mite (HDM) allergic rhinitis is difficult. The nasal provocation test (NPT) has been shown to be the most pertinent, but several methods are available. According to guidelines, the NPT requires a skin end-point titration and an objective measurement of nasal patency. Hence, NPT is time consuming and its use is limited. OBJECTIVE To evaluate the sensitivity, specificity, and safety of a new, more rapid, and simple alternative NPT (NPT-R) to HDM. METHODS Eighty-eight patients with from rhinitis (49 allergic to HDM and 39 controls with and without atopy) were included. Allergic rhinitis to HDM was confirmed by a "classic" NPT based on the Lebel score and rhinomanometry. After a period of 4 weeks, NPT-R was performed and only the clinical score was measured. RESULTS The study population was young (mean ± SD, 27.7 ± 8.5 years old), composed mostly of women (61 vs 27 men), and 24% reported asthma. The sensitivity and specificity of NPT-R were 83.7% and 100%, respectively. The correlation between the NPTs was statistically significant (0.833, P < .0001, n = 88) and the 2 NPTs were completely safe. Performing NPT-R was more rapid (mean ± SD, 22 ± 8 minutes) than the classic NPT (97 ± 20 minutes). CONCLUSION The NPT-R is safe and easier and faster than the classic NPT. This new method appears to be a very useful tool in the diagnosis of HDM allergic rhinitis when the diagnosis is uncertain or before initiating immunotherapy.

Abstract
BACKGROUND Allergic rhinitis is a type I allergic disease of the nasal mucosa, and is characterized by paroxysmal sneezing, watery rhinorrhea, and nasal blockage. In seasonal allergic rhinitis subjects, even subthreshold allergen doses have been found to cause inflammatory cell infiltration in the nasal mucosa. This study aimed to investigate the presence of nasal obstructions and symptoms in seasonal allergic rhinitis subjects by assessing an exercise challenge test (ECT) outside of the pollen season. METHODS Twenty patients and 20 healthy children who were admitted to the Osmangazi University Medical School Pediatric Allergy Clinic were included in the study in a pollen free season. The total nasal airflow and visual analog scale (for rhinorrhea, nasal congestion, sneezing, and itching) and pulmonary function tests were evaluated before and after each ECT. The nasal airflow and resistance changes were evaluated with anterior rhinomanometry. RESULTS Eight patients and one healthy child had nasal obstructions after the ECT. There was a significant difference in the exercise-induced nasal obstructions between the 2 groups (p = 0.02). Eighteen children with exposure to tobacco smoke in the patient and control groups had lower forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and forced expiratory flow 25% to 75% (FEF25-75 ) values than the children without exposure to tobacco smoke. CONCLUSION The prevalence of exercise-induced nasal obstruction in children with seasonal rhinitis out of the pollen season is 40%. We showed that minimal persistent inflammation and nasal symptoms can also be diagnosed in rhinitis children in a symptom-free period.

Abstract
The nasal provocation test (NPT) is a simple procedure with high specificity and sensitivity that is used in the investigation of allergic and nonallergic diseases. Uniform standards are of particular importance in the clinical setting and for the comparability of clinical and basic allergy research. These standards should cover the composition, dosage and pharmacological formulation of provocative substances (e.g. allergen extracts), the necessity of titration, allergen application methods and the evaluation criteria for a positive NPT reaction. Detection of various mediators and cytokines in nasal discharge can be very useful in the late phase reactions. NPT finds specific applications in studies of local IgE secretion in the nasal mucosa, the diagnosis of analgesic intolerance and in assessments of the efficacy of specific immunotherapies. Additional parameters warranting further evaluation include provocation with cold dry air in nasal hyperreactivity patients and nasal nitric oxide formation. Determination of nasal blood flow during NPT provides an additional clinical parameter.

Abstract
AIM To evaluate nitric oxide and interleukin (IL)-6, IL-8 and IL-13 in the exhaled breath of children with allergic rhinitis (AR), before and after intranasal allergen exposure. METHODS A total of 49 children with AR – comprising 20 who also had episodic asthma (AR+A) and 29 without asthma (AR) – were compared with 34 healthy controls. Nitric oxide concentrations in exhaled air (eNO) and IL-6, IL-8 and IL-13 in exhaled breath condensates (EBC) were measured in winter, outside the natural allergen exposure season, before and after an intranasal allergen challenge. RESULTS The mean concentrations of eNO, IL-6 and IL-13 were significantly higher in the two AR groups. The concentration of IL-8 was below the assay detection limit in all EBC samples. The intranasal allergen challenge increased IL-13/EBC levels in both AR groups, but did not influence mean concentrations of eNO, IL-6 or IL-8. No challenge-related changes in IL-13/EBC were observed in the allergen-exposed controls or placebo-exposed children. CONCLUSION Despite local application, the intranasal allergen challenge increased IL-13/EBC concentration in the AR children. As EBC reflects the status of lower airway segments, our observation may support the 'united airways' hypothesis, suggesting a functional link between the upper and lower airways.

Abstract
Optimal functioning of the immune system is crucial to human health, and nutrition is one of the major exogenous factors modulating different aspects of immune function. Currently, no single marker is available to predict the effect of a dietary intervention on different aspects of immune function. To provide further guidance on the assessment and interpretation of the modulation of immune functions due to nutrition in the general population, International Life Sciences Institute Europe commissioned a group of experts from academia, government and the food industry to prepare a guidance document. A draft of this paper was refined at a workshop involving additional experts. First, the expert group defined criteria to evaluate the usefulness of immune function markers. Over seventy-five markers were scored within the context of three distinct immune system functions: defence against pathogens; avoidance or mitigation of allergy; control of low-grade (metabolic) inflammation. The most useful markers were subsequently classified depending on whether they by themselves signify clinical relevance and/or involvement of immune function. Next, five theoretical scenarios were drafted describing potential changes in the values of markers compared with a relevant reference range. Finally, all elements were combined, providing a framework to aid the design and interpretation of studies assessing the effects of nutrition on immune function. This stepwise approach offers a clear rationale for selecting markers for future trials and provides a framework for the interpretation of outcomes. A similar stepwise approach may also be useful to rationalise the selection and interpretation of markers for other physiological processes critical to the maintenance of health and well-being.

Abstract
A 21-year-old patient experienced asthmatic attacks when cleaning the cage of his budgerigar. Skin tests and radioallergosorbent test were positive to grass pollen and negative for budgerigar feathers and feces. When the food of the bird, a mixture of grain, was tested, a positive reaction to millet was found. Nasal provocation test with millet was positive. Specific immunoglobulin E antibodies against millet were detected in the radioallergosorbent test and in immunoblot analysis. The immunoblot showed specific immunoglobulin E antibodies against a 60-kd protein in millet of birdseed and against a 60-and 36-kd protein in common millet. Immediate-type allergy to millet is rare and occurs mostly as anaphylactic reaction after ingestion of millet but may also occur as asthmatic attack after inhalation of millet.

Abstract
BACKGROUND A neuroallergic interaction was reported in the pathogenesis of allergic rhinitis (AR), but the pathophysiology of nonallergic rhinitis (NAR) is poorly understood. We aimed to explore the contribution of neuroallergic mechanisms to the pathogenesis of NAR. METHODS Subjects were divided into three groups - NAR patients (n = 25), AR patients (n = 16) and the control group (n = 10) - and were assessed using the nasal provocation test (NPT) with house dust mite. Total symptom scores, nasal inspiratory peak flow and nasal lavage were performed before and after NPT. Nasal brushing and scraping was done after NPT. RESULTS NPT was positive in NAR (52%) and AR (100%) patients and negative in all controls. After NPT, total symptom scores increased in both rhinitis groups. Post-NPT values of nasal inspiratory peak flow decreased only in AR patients. NAR patients showed a similar inflammatory cell profile in the nasal smears to AR patients which was different in controls. There were more tryptase- and immunoglobulin E (IgE)-positive cells in the nasal mucosa of AR patients, and more substance-p-positive cells were observed in NAR patients compared with controls. However, IgE- and tryptase-positive cells in NAR patients and substance-p-positive cells in AR patients were detectable in nasal mucosa, but rarely in the controls. Comparing the values before and after NPT, tryptase significantly increased in the nasal lavages of AR and NAR patients, while house dust mite-specific IgE did not change. CONCLUSIONS We showed the existence of a common pathophysiological mechanism with different contributions in AR and NAR. We conclude that the difference in dominance of neuroallergic ways may determine the major phenotype of rhinitis.

Abstract
BACKGROUND Nasal blood flow (NBF) plays a crucial role in many physiological and pathological processes but its regulation and relation to other rhinological outcomes is poorly understood. OBJECTIVES We measured nasal airway patency, nasal blood flow, and subjective and objective measures of decongestion and assessed their reproducibility and responsiveness. METHODS 19 healthy adults attended twice. A dose-response curve was constructed using doubling doses of oxymetazoline of 25 μg, 50 μg, 100 μg, and 200 μg at 20 minute intervals. Peak nasal inspiratory flow (PNIF) and nasal airway resistance (NAR) were measured at baseline and after each successive dose, NBF using laser Doppler flowmetry at baseline, 50 μg and 200 μg and a decongestion visual analogue scale after the final dose. RESULTS After the final dose of oxymetazoline, NBF decreased by a mean (95% CI, P value) of 139.6 (108.3-170.8, P < .001) units and 99.4 (68.1-130.7, P < .001) units, PNIF increased by 48.9 (22.0-75.8, P < .001) L.min-1 and 38.9 (12.0-65.8, P = .003) L.min-1, and NAR decreased by 0.1 (0.02-0.15, P < .001) Pa/s/cm(3) and 0.09 (0.02-0.15, P = .002) Pa.s.cm-3 at the first and second visits respectively. The area under the curve of decongestion was not significantly different between visits for each variable. The standardized response means for the decongestant response were as follows: NBF, 1.41; PNIF, 1.03; and NAR, 0.97. CONCLUSIONS Nasal blood flow using laser Doppler flowmetry is a sensitive and reproducible outcome to decongestion with oxymetazoline, similar to nasal patency and symptoms.
