Abstract
The management of asthma has fundamentally changed during the past decades. The present guideline for the diagnosis and treatment of asthma was developed for respiratory specialists who need detailed and evidence-based information on the new diagnostic and therapeutic options in asthma. The guideline shows the new role of biomarkers, especially blood eosinophils and fractional exhaled NO (FeNO), in diagnostic algorithms of asthma. Of note, this guideline is the first worldwide to announce symptom prevention and asthma remission as the ultimate goals of asthma treatment, which can be achieved by using individually tailored, disease-modifying anti-asthmatic drugs such as inhaled steroids, allergen immunotherapy or biologics. In addition, the central role of the treatment of comorbidities is emphasized. Finally, the document addresses several challenges in asthma management, including asthma treatment during pregnancy, treatment of severe asthma or the diagnosis and treatment of work-related asthma.

A Comparative Study of Symptoms, Nasal Eosinophilia and Pulmonary Function Tests Before and After Short Term Treatment with Corticosteroid Nasal Spray in Patients with Allergic Rhinitis. Indian J Otolaryngol Head Neck Surg 2022; 74:1001-1008.

Abstract
Allergic rhinitis has been on the rise because of urbanization and major population shift in addition to changes in the particulate matter in the atmosphere. Intranasal corticosteroid sprays are recommended as first-line prescription treatment in all cases of allergic rhinitis. The propensity of co-existing non-apparent lower airway hyper-responsiveness is also on the rise and must be evaluated. The aim of this study is to compare the symptomatic improvement, changes in nasal eosinophilia and asymptomatic airway hyper responsiveness before and after short term treatment with steroid nasal spray. Fifty patients meeting the inclusion criteria for allergic rhinitis with no symptoms of asthma underwent pulmonary function tests and assessment of symptoms before and after one-month treatment with inhalational steroid nasal spray (Fluticasone Furoate), in the standard adult dosage. Based on TNSS (Total nasal symptom score) and TOSS (Total ocular symptom score), all 50 patients showed significant improvement after treatment. Among 20 patients with > 50 eosinophils per high power field, 80% had 0-10 eosinophils per high power field on nasal smear after treatment. Among 40 patients with mild large airway obstruction, 37 showed significant improvement in FEV1 data. Also FEV1/FVC data showed significant improvement. Significant improvement (FEF25-75 > 50%) was also noticed in small airway disease after treatment among the 5 patients. The study showed that lower airway hyper responsiveness coexists with allergic rhinitis and treating allergic rhinitis with just steroid nasal spray assists in reducing the former, supporting the concept of Unified Airway Disease (UAD).

Abstract
Various factors affect the maturation of the infantile immune system both prenatally and postnatally, including risk and protective factors from the environment, nutrition, genetics and epigenetics. The microbiome seems to play a substantial role. The complex interaction and regulation of all these factors is ultimately decisive for whether a child develops an allergy during the course of development of the immune system. The genetic components play a decisive role in the development of allergic diseases. The epigenetic regulation could represent a mechanism where environmental influences act upon the immune regulation in the emergence of allergic diseases. The main factors in the pathophysiology of allergic reactions are a dysregulation of various cells of the innate and acquired immune systems as well as their interaction. This review describes the role of various T helper cell types in allergic diseases. The incidence and duration of airway infections are clearly increased in allergic patients compared to nonallergic controls. In addition to functional aspects, the reason for the more frequent infections is an impairment of the immune defence by the allergy-related persisting inflammation of the mucous membranes. These mechanisms must be differentiated from a true immunodeficiency. Allergic rhinitis (AR) and bronchial asthma are nowadays no longer defined as separate diseases but as two forms of expression of an atopic entity with a similar pathology. Both diseases can be mediated by immunoglobulin E and be elicited by identical triggers. A bronchial hyperreactivity is detectable in the majority of patients with AR but without clinical asthma.

Abstract
Introduction Allergic rhinitis (AR) is a common IgE -mediated inflammatory condition characterised by sneezing, nasal congestion, itching and rhinorrhoea. Nasal allergy is a strong risk factor for the onset of asthma in adults. Bronchial hyper-responsiveness (BHR) is a distinct feature of pathophysiology in asthma. Spirometric parameters like Forced Expiratory Volume in first second [FEV1] and Forced Expiratory Flow [FEF 25-75%] are known to be impaired in patients with allergic rhinitis. We studied these parameters in subjects of AR who have never experienced any chest symptoms. It is well known that, subjects with allergic rhinitis are at greater risk of developing overt bronchial asthma in future. Methods All patients presented with symptoms of allergic rhinitis without history of bronchial asthma were included. Patients those who were clinically diagnosed with allergic rhinitis were evaluated with absolute eosinophilic count, serum IgE and Spirometric assessment. In spirometry, post bronchodilator FEV1 reversibility and post bronchodilator FEF 25-75% values were used to assess lower airway abnormalities. Results Among 61 subjects, 32 were males and 29 were females. The maximum numbers [28] of patients were in 21-35 age group. Absolute eosinophil count was elevated in 38% of patients. 33% of patients showed elevated IgE values above 1000. 43% of patients showed FEV1 reversibility which is a sign of Bronchial hyperreactivity. 5% of patients showed impaired post bronchodilator FEF 25-75% which indicates presence of small airway disease. There was significant correlation between FEV1 reversibility and elevated IgE. Conclusion Impaired spirometric parameters indicate coexistence of bronchial impairment and hence predisposition to progression from allergic rhinitis alone to overt asthma in future. Thus careful evaluation of lower airway has to be done to rule out coexisting subclinical asthma.

Abstract
BACKGROUND Fractional exhaled nitric oxide (FeNO) is a well-known marker of type-2 inflammation. FeNO is elevated in asthma and allergic rhinitis, with IgE sensitization as a major determinant. OBJECTIVE We aimed to see whether there was an independent association between upper airway inflammatory disorders (UAID) and FeNO, after adjustment for asthma and sensitization, in a multi-centre population-based study. METHODS A total of 741 subjects with current asthma and 4155 non-asthmatic subjects participating in the second follow-up of the European Community Respiratory Health Survey (ECRHS III) underwent FeNO measurements. Sensitization status was based on measurement of IgE against airborne allergens; information on asthma, UAID and medication was collected through interview-led questionnaires. Independent associations between UAID and FeNO were assessed in adjusted multivariate regression models and test for interaction with perennial sensitization and asthma on the relation between UAID and FeNO were made. RESULTS UAID were associated with higher FeNO after adjusting for perennial sensitization, asthma and other confounders: with 4.4 (0.9-7.9) % higher FeNO in relation to current rhinitis and 4.8 (0.7-9.2) % higher FeNO in relation to rhinoconjunctivitis. A significant interaction with perennial sensitization was found in the relationship between current rhinitis and FeNO (p = .03) and between rhinoconjunctivitis and FeNO (p = .03). After stratification by asthma and perennial sensitization, the association between current rhinitis and FeNO remained in non-asthmatic subjects with perennial sensitization, with 12.1 (0.2-25.5) % higher FeNO in subjects with current rhinitis than in those without. CONCLUSIONS & CLINICAL RELEVANCE Current rhinitis and rhinoconjunctivitis was associated with higher FeNO, with an interaction with perennial sensitization. This further highlights the concept of united airway disease, with correlations between symptoms and inflammation in the upper and lower airways and that sensitization needs to be accounted for in the relation between FeNO and rhinitis.

Abstract
Our understanding of the relationship between the upper and lower airways has greatly increased as a consequence of epidemiologic and pharmacologic studies. A consistent body of scientific evidence supports the concept that rhinitis, rhinosinusitis and asthma may be the expression of a common inflammatory process, which manifests at different sites of the respiratory tract, at different times. This paradigm states that allergic reactions may begin at the local mucosa, but tend to propagate along the airway. Central to the allergic diathesis is the eosinophil and its interaction with the airway epithelium. The implications of the interplay between upper and lower airway are not only academic, but also important for diagnostic and therapeutic reasons. Furthermore, there is significant overlap in symptomatology and pathophysiology for childhood sleep disordered breathing (SDB) and asthma. Recent evidence supports an association between these two conditions, but causality has not been demonstrated. Regardless, it is important to recognize the overlap and evaluate for the other condition when one is present. In children with poorly controlled asthma, the presence of SDB may significantly contribute to asthma morbidity and, as such, should be actively excluded. On the other hand, clinical evaluation for asthma should be considered in children with SDB. Future robust longitudinal research is needed to explore the association between upper and lower airway diseases using objective measures in children.

Abstract
Background Allergic rhinitis may be associated with asthma. Forced expiratory flow between 25 and 75% of vital capacity (FEF25–75) is a measure of small airways narrowing. The aim of this study was to evaluate whether patients with seasonal allergic rhinitis (SAR) without symptoms of asthma might, nevertheless, have airways obstruction both in and out of the pollen season. Methods Fifty patients (mean age, 23.7 ± 4.9 years) with SAR were evaluated both during and outside the pollen season. All of them had moderate–severe grade of nasal obstruction. Total symptom score, rhinomanometry, nasal lavage, nasal scraping, spirometry, and methacholine (MCH) bronchial challenge were assessed in all subjects. Results Although data on forced vital capacity and response to MCH were similar in and out of the pollen season, all other parameters were markedly different. The major finding of the study was that FEF25–75 was significantly associated with nearly all of the parameters considered, including bronchial hyperreactivity, with Pearson R ranging from 31 to 75% and differences in mean FEF25–75 ranging between 14.5 and 16.5% of predicted. The more significant association was with nasal airflow in the pollen season (R = 82.8%; p < 0.001). A significant association persisted for all parameters while controlling for season. Conclusion This study highlights the link between upper and lower airways and the role of FEF25–75 as an early marker of bronchial impairment in those patients with SAR alone.

Abstract
BACKGROUND: Allergic rhinitis is characterized by a Th2-dependent inflammation. Nasal obstruction largely depends on allergic inflammation. OBJECTIVE: The aim of this study was to evaluate the possible role of the symptom nasal obstruction in assessing patients with hay fever. METHODS: Fifty patients (mean age, 23.7 ± 4.9 years) with hay fever were evaluated both during and outside pollen season. All of them had moderate-severe grade of nasal obstruction. Total symptom score (TSS), rhinomanometry, nasal lavage, nasal scraping, spirometry, and methacholine bronchial challenge were performed in all subjects. RESULTS: During the pollen season, patients with severe nasal obstruction showed significantly higher values of TSS, IL-4, IL-5, IL-8, nasal eosinophils and neutrophils, and significantly lower values of nasal airflow, IFNγ, FEV1, FVC, and FEF 25-75 in comparison with patients with moderate nasal obstruction. Twenty (83%) patients with severe nasal obstruction showed bronchial hyperreactivity (BHR), whereas only 6 (25%) patients with moderate nasal obstruction had BHR. Outside the pollen season overlapping results were observed. CONCLUSIONS: This study provides evidence about the key role played by nasal obstruction in assessing patients with allergic rhinitis.

Abstract
Nasal allergy is characterized by an IgE mediated inflammatory response of nasal mucosa to allergens and it has a close association with Asthma. Nasal allergy has been demonstrated to be a strong risk factor for the onset of asthma in adults. Spirometric parameters like Forced expiratory volume at timed interval of 1 s (FEV1) and forced expiratory flow (FEF25-75 %) are impaired in patients with nasal allergy or allergic rhinitis. The FEF25-75 % has been evidenced to be a reliable marker of early bronchial impairment in nasal allergy. Nasal allergy may be considered as the first step of the progression of respiratory allergy towards asthma. It has been demonstrated that FEF25-75 % is useful in predicting the presence of airway hyper responsiveness.It may be a more sensitive indicator of chronic airway obstruction than FEV1 and is considered as a risk factor for the persistence of respiratory symptoms in asthmatic patients. The impact of allergic rhinitis or nasal allergy on asthma (ARIA) guidelines, clearly underlined the role of allergic rhinitis as risk factor for asthma development. The possible presence of spirometric abnormalities in patient with allergic rhinitis has been well documented. So keeping this in mind, present study is undertaken to evaluate the impairment of spirometric parameters, like FEV1, FEF25-75 %, and forced vital capacity, in patients with nasal allergy and to predict the presence of airway hyper responsiveness.

Abstract
BACKGROUND Epidemiological and clinical studies suggest a relationship between rhinitis and asthma. Upper and lower airways may be influenced by a common inflammatory process. OBJECTIVE This study aimed to investigate the relationships between rhinitis symptom scores, and both nasal and bronchial airflow among children with seasonal allergic rhinitis (SAR) by means of spirometric and rhinomanometric measurement during and outside the pollen season. METHODS Twenty-nine children with both seasonal allergic rhinitis and asthma (AR+A), 30 children with SAR and no asthma (AR) and 36 non-allergic healthy children were evaluated prospectively during and outside the pollen season. Symptom severity was evaluated using both total symptom score and visual analog score (VAS). All participants also received rhinomanometric evaluation and pulmonary function testing. RESULTS In children with SAR the median total nasal flow, FEV1, FEF25-75 values were lower than control group during pollen season (p=0.01, p<0.001 and p<0.001 respectively). They had also higher total nasal resistance compared with control groups (p=0.01). Nasal symptom scores were higher among patients with concurrent asthma than patients who had only SAR out of pollen season (p<0.001). There was no significant difference between SAR participants with or without asthma and control group in terms of total nasal flow and total nasal resistance measured out of season (p=0.105 and p=0.19). FEF25-75 values of patients with and without asthma were significantly lower than those of controls out of season (p=0.022, p<0.001 respectively). CONCLUSION Our data suggests that as the presence of AR worsens asthma control, the presence of asthma may worsen symptoms of AR out of pollen season. We found that total nasal flow, FEV1, FEF25-75 values of patients with SAR were lower than those of controls out of season. FEF25-75 values of patients with asthma and without asthma were significantly lower than those of controls out of season. Thus, a careful evaluation of lower airways should be performed in even patients with seasonal allergic rhinitis alone.

Abstract
Background: Diagnosis and treatment of chronic and recurrent sinusitis in children is of potential importance and many factors can havean influence on it. This study assessed the chronic and recurrent sinusitis and affecting factors, as well as the role of allergy in its course and treatment in children. Materials and Methods: A total of 106 children with the diagnosis of chronic or recurrent sinusitis, referred to specialty clinics of otolaryngology and allergy of Tabriz Children Educational-Medical centres since 2010 to 2012, were enrolled. The history and physicalexamination findings were recorded for all patients and allergy Prick test was done for all. Response to treatment was evaluated during the follow-up visits. Results: The mean age of studied patients was 6.5 ± 2.9 years. Of all the patients, 54 (50.9%) were male and 52 (49.1%) were female. Skin Prick test was positive in 69.8%. Response to treatment was seen in 86.8% of the patients while 7.5% did not have any favourable outcome. Anti-allergic treatment caused better outcomes in patients with positive Skin Prick test than those with negative results. Conclusion: The prevalence of allergic disease in children with chronic or recurrent sinusitis is considerable and anti-allergic treatments can result infavourable therapeutic outcomes in children with sinusitis, especially with positive skin prick test results.

Abstract
BACKGROUND The united allergic airway is a theory that connects allergic rhinitis (AR), chronic rhinosinusitis, and asthma, in which seemingly disparate diseases, instead of being thought of separately, are instead viewed as arising from a common atopic entity. OBJECTIVE This article describes patients with such diseases; explores ideas suggesting a unified pathogenesis; elucidates the various treatment modalities available, emphasizing nasal corticosteroids and antihistamines; and provides an update of the literature. METHODS A literature review was conducted. CONCLUSION The aggregation of research suggests that AR, asthma, and chronic rhinosinusitis are linked by the united allergic airway, a notion that encompasses commonalities in pathophysiology, epidemiology, and treatment.

Abstract
BACKGROUND Allergic rhinitis and bronchial asthma can coexist and affect each other. OBJECTIVE To investigate the relationship between the postseasonal increase in the concentration of leukotriene (LT) B4 and LTE4 in exhaled breath condensate (EBC) and bronchial responsiveness to methacholine (BRM) in patients with seasonal allergic rhinitis (SAR). METHODS In 28 patients with SAR and 50 healthy study patients, the leukotrienes were measured in EBC during and after the pollen season by gas chromatography/mass spectrometry. The BRM was determined after the pollen season. RESULTS In 7 patients with SAR, significantly increased concentrations of both the leukotrienes were found in EBC during and 5 months after the pollen season. The following seasonal and postseasonal median values were measured in patients with SAR in comparison with control patients: LTB4: 131 and 90 pg/mL vs 80 and 79 pg/mL, P < .001 and P = .03, respectively; LTE4: 122 and 86 pg/mL vs 76 and 74 pg/mL, P < .001 and P = .02, respectively. Five months after the pollen season, the concentrations of LTB4 and LTE4 decreased with respect to their seasonal values (90 and 86 pg/mL, respectively, P < .001, for both leukotrienes). In 7 patients with SAR and leukotriene levels exceeding the reference limits, significantly increased BRM was also found (LTB4: P = .02; LTE4: P = .002). CONCLUSIONS The seasonal and postseasonal increases in LTB4 and LTE4 concentrations in EBC of the patients with SAR correlated significantly with the later increase in BMR. This relationship could provide a useful predictive parameter for early inflammatory processes in the lower airways of patients with allergic rhinitis.

Abstract
BACKGROUND A methacholine challenge may be used in confirming the diagnosis of asthma, occupational asthma, or reactive airways dysfunction syndrome (RADS) through identification of bronchial hyperreactivity (BHR). While sensitivity of the test in diagnosing clinically significant asthma is excellent, specificity of the test is poor. Since there are many conditions which have been associated with BHR, a positive test must be interpreted cautiously. METHODS This paper reviews potential causes of a positive methacholine challenge other than asthma or RADS which have been reported in the medical literature. RESULTS Factors which may be associated with a positive methacholine test include test methodology, normal variation of BHR in the general population, and numerous medical conditions. CONCLUSIONS In cases of inhalation exposure evaluations, alternative explanations must be considered when determining whether a causal association exists between the exposure and a positive methacholine test result.

Abstract
Inflammatory processes affecting nasal and bronchial mucosa are similar in nature. The purpose of this study was to examine whether children with perennial allergic rhinitis, without underlying asthma, have impaired pulmonary function. We also investigated whether nasal corticosteroids and loratidine would improve the pulmonary function tests of those children with impaired lung function. Fifty subjects with moderate/severe persistent allergic rhinitis due to exclusively dust mite sensitization and no past medical history suggestive of asthma were assessed. The control group consisted of 26 matched healthy subjects. Subjects with airway obstruction, as detected by forced expiratory volume/1 s (FEV1) or forced expiratory flow from 25/% to 75% (FEF(25-75)) values <80% of those predicted, were treated with loratidine, once a day for 10 days, and daily nasal budesonide for 3 months. We found that 11 of 50 patients (22%) with perennial allergic rhinitis had impaired pulmonary function (FEF(25-75) values <80%), compared to 1/26 (3.8%) of the control group (p < or = 0.05). Reversibility was observed in 9/11 (81.8%), mean 24.7% +/- 10.3%. Within 3 months of treatment, 7/10 had FEF(25-75) > 80% of their predicted values as well as significant improvements in their FEV1 (p = 0.04), and FEV1/FVC (p = 0.04). We conclude that a substantial proportion of children with perennial allergic rhinitis have diminished FEF (25-75) values and reversible airway obstruction. Nasal corticosteroids improve the pulmonary function tests of these children with impaired lung function.

Abstract
BACKGROUND Given the observed association between smoking, inflammation and airway hyperresponsiveness (AHR) one may predict that smoking cessation may improve AHR. However, only a few studies have investigated the effect of smoking on AHR and their results appear to be conflicting depending on the stimulus used in their bronchoprovocation protocol. The aim of the current study was to compare changes in AHR between direct (methacholine (Mch)) and indirect (adenosine 5'monophosphate (AMP)) stimuli before and at different time points after smoking cessation in smokers with allergic rhinitis (+/-asthma). METHODS We have prospectively studied changes in AHR to inhaled Mch and AMP in smokers with allergic rhinitis (+/-asthma), before and at 6 and 12 months after smoking cessation. RESULTS It was found that 28% (16/57) of the participants had quit smoking by the end of the study. No significant change in AHR was observed in smoking cessation failures. A significant improvement in AHR to AMP but not Mch was observed 6 months after smoking cessation in quitters; a 1.2 doubling concentrations change in PC20 AMP was measured whereas only a 0.4 doubling concentrations change was observed for PC20 Mch. However, after 12 months smoking cessation the improvement in AHR became significant for both AMP and Mch, their dose-response curves being displaced to the right to a similar extent (1.4 and 1.1 doubling concentrations for AMP and Mch, respectively). CONCLUSION Smoking cessation can improve AHR in smokers who quit with a 6 months improvement being reported for the airways response to AMP but not Mch. AMP challenge may detect earlier changes in AHR in smokers during smoking cessation.

Abstract
BACKGROUND There is a paucity of data on the prevalence, risk factors and natural history of rhinitis in early childhood. OBJECTIVE Within the context of a whole-population birth cohort we investigated the prevalence of and risk factors for current rhinoconjunctivitis (CRC) at age 5 years. METHODS Children were followed prospectively to age 5 years [questionnaires (n = 815), skin testing (n = 717), specific immunoglobulin E (n = 478), lung function (n = 711), dry air challenge (n = 556)]. Endotoxin and allergen exposures were measured in dust samples. RESULTS The prevalence of rhinitis ever, current rhinitis and rhinoconjunctivitis was 28.2%, 26.1%, and 12.1%, respectively. Asthma, wheeze and eczema coexisted with CRC (P < or = 0.01). In a multivariate model, maternal asthma (OR 2.38, 95% CI: 1.30-4.38, P = 0.005), paternal hay fever (1.96, 1.11-3.46, P = 0.02) and sensitization to grass (3.46, 1.86-6.42, P < 0.001) and cat (2.42, 1.14-5.18, P = 0.02) remained significant and independent associates of CRC. Whilst almost half of children with CRC were nonatopic, there was little difference in risk factors between atopic and nonatopic CRC. Amongst children with current wheeze, the presence of concurrent CRC had no effect on either severity or frequency of wheezy episodes. There was no difference in specific airway resistance, forced expiratory volume in 1 second (FEV(1)) or airway reactivity between children with and without CRC after adjustment for the presence of wheeze. CONCLUSION Family history of allergic disease and sensitization to inhalant allergens are risk factors for rhinoconjunctivitis in preschool children. In this age group, there is no association between the presence of rhinoconjunctivitis and severity of wheeze, increased airway reactivity and reduced lung function.

Abstract
PURPOSE OF REVIEW The relationship between allergic rhinitis and asthma has intrigued practicing physicians since the turn of the century. Investigations during the past two decades have led to an increased understanding of this relationship. RECENT FINDINGS A growing body of evidence clearly demonstrates that patients with allergic rhinitis, in the absence of asthma, have distinct abnormalities of lower airway function, including alterations in physiology, histology and biochemistry. In addition, epidemiologic surveys have consistently shown allergic rhinitis as an independent risk factor for developing asthma, and that preexisting abnormalities in lung function may predispose to lower airway disease development. Clinical trials show that specific allergen immunotherapy for children and adults with seasonal allergic rhinitis reduces the risk of developing asthma. In patients with established asthma and concomitant allergic rhinitis, several medications have significant effects upon the upper and lower airways, including intranasal corticosteroids, oral antihistamines, and leukotriene receptor antagonists. SUMMARY Our understanding of the natural history of allergic rhinitis could lead to improvements in early intervention, potentially preventing the progression of allergic rhinitis to asthma. Aggressive treatment of rhinitis in patients with concomitant asthma may enhance asthma outcomes and quality of life for all patients with these chronic diseases.

Abstract
BACKGROUND Tumor necrosis factor alpha (TNF-alpha) is involved in the up-regulation of intercellular adhesion molecule 1 (ICAM-1). Allergic rhinitis is often associated with bronchial hyperresponsiveness. OBJECTIVE We investigated the relationship between allergic airway disease severity and serum concentrations of soluble ICAM-1 (sICAM-1) and TNF-alpha and nasal expression of ICAM-1. METHODS Serum concentrations of TNF-alpha and sICAM-1 were investigated in 85 adults with persistent rhinitis and 90 patients with asthma. Seventy patients with rhinitis were challenged with methacholine. Nasal biopsy for ICAM-1 expression was performed in 6 patients with moderate-severe rhinitis and in 6 patients with mild rhinitis. RESULTS In patients with rhinitis, serum sICAM-1 concentrations were as follows: group without bronchial hyperresponsiveness (n = 29), 206.85 ng/mL; group with bronchial hyperresponsiveness but without asthma symptoms (n = 20), 233.39 ng/mL; and group with newly recognized asthma (n = 21), 260.06 ng/mL. The sICAM-1 level was significantly lower in patients with mild rhinitis (216.21 ng/mL) than in patients with moderate-severe rhinitis (244.08 ng/mL). Nasal ICAM-1 expression was significantly higher in the moderate-severe rhinitis group than in the mild rhinitis group. In patients with asthma, serum concentrations of sICAM-1 were as follows: patients with mild asthma, 272.8 ng/mL; patients with moderate asthma, 340.16 ng/mL; patients with severe asthma without oral corticosteroids therapy, 426.74 ng/mL; and patients with severe asthma with oral corticosteroids therapy, 314 ng/mL. The serum TNF-alphaa concentration differed between patients with rhinitis (n = 15) (1.065 pg/mL) and patients with asthma (n = 12) (3.46 pg/mL). Among patients with asthma, TNF-alpha concentrations were similar in all groups classified according to the disease severity. CONCLUSIONS sICAM and ICAM-1 expression correlates with airways diseases severity.

Abstract
BACKGROUND It has been reported that nasal allergy influences the lower airway inflammation and functions. We elucidated whether nasal allergy would contribute to lower airway inflammation and functions. METHODS 266 subjects aged 21-39 years were interviewed with special emphasis on history of asthma and nasal allergies (perennial allergic rhinitis (PAR) and seasonal allergic rhinitis (Japanese cedar pollinosis; PO)). Symptomatic subject was defined when nasal symptoms were present during a 3-week study period. Pulmonary function, provocative concentration of methacholine causing a 20% fall in forced expiratory volume in 1 s (PC20), capsaicin cough threshold defined as capsaicin concentration eliciting 5 or more coughs (C5) and eosinophil percentage in hypertonic saline-induced sputum were measured. RESULTS Based on the interview, 232 subjects without asthma were divided into symptomatic (n = 25) and asymptomatic (n = 22) PAR, PO on-season (n = 15) and off-season (n = 36), and non-nasal allergy subjects (control) (n = 134). Sputum eosinophils were significantly greater in symptomatic PAR than another four groups (p < 0.01). FEV1/FVC ratio was significantly lower in PAR than control (p < 0.05). Maximum mean expiratory flow was lower in PAR than control (asymptomatic: p < 0.05, symptomatic: p = 0.06). C5 was not different among groups. PAR tended to have a lower PC20 compared to control (symptomatic: p = 0.078; asymptomatic: p = 0.086). CONCLUSIONS These results suggest that eosinophilic inflammation occurred in symptomatic period of PAR may contribute to development of lower airway remodeling and bronchial hyperresponsiveness. Reversely, PO may not be associated with lower airway eosinophilic inflammation or abnormal bronchial functions. Nasal allergy dose not influence the cough reflex sensitivity.

Abstract
With the rising world burden of asthma, it is crucial to define the early events that lead to chronic inflammation and airway remodelling. Chronic airway inflammation appears to be the culmination of both local epithelial dysfunction and a more generalised immune dysregulation that results in allergic predisposition. A number of antenatal and early postnatal events may contribute to this. However, although a systemic propensity for allergic responses (typically food allergy) frequently pre-exists in children who go on to develop asthma, there is still uncertainty over whether epithelial changes occur as a primary event or whether these are consequent to this evolving systemic propensity for type 2 T-helper cell allergic responses. Many children with asthma already show many of the features of chronic airway inflammation, with epithelial desquamation, inflammatory cell infiltrates, subepithelial basement membrane thickening and fibrosis, goblet cell hyperplasia and smooth muscle hypertrophy. These changes can be evident before asthma is diagnosed, and there is also evidence that airway inflammation and early remodelling can progress in a subclinical state. New studies suggest that early airway damage is irreversible and that subsequent lung function is 'set' in the first years of life. These observations highlight the need to identify affected or at-risk children early and to develop interventions that can abort or prevent ongoing airway inflammation and remodelling.

Abstract
PURPOSE OF REVIEW This review examines the role of the upper airways in the atopic march. Evidence examining the theory that allergic rhinitis precedes asthma will be discussed. In addition, the role of allergic rhinitis as an end point in the atopic march will be reviewed. RECENT FINDINGS Ciprandi and colleagues found that nasal symptoms, airflow and markers of inflammation (eosinophils, cytokine levels) directly correlated with lower airway markers. This confirms previous studies finding that many patients with allergic rhinitis have lower airway hyperreactivity or bronchial hyperresponsiveness and the link between upper and lower airways. Leynaert and colleagues questioned over 90 000 individuals and found that patients with rhinitis have increased risk for asthma and lower airway reactivity compared with patients without rhinitis. In the German Multicenter Atopy Study, a longitudinal study of 1300 children, patients with atopic dermatitis were found to have increased risk for asthma at 7 years of age. Patients with atopic dermatitis and no wheezing in the first 3 years, however, did not have an increased risk for developing current wheezing or bronchial hyperresponsiveness at 7 years of age. It was proposed that atopic dermatitis and asthma are linked, but atopic dermatitis does not precede asthma. SUMMARY Allergic rhinitis is a risk factor for asthma and can precede asthma in the atopic march.

Abstract
BACKGROUND Allergic rhinitis and its impact on asthma (ARIA) document underlines the link between upper and lower airways. Patients suffering from allergic rhinitis frequently (up to 80%) show bronchial hyperreactivity (BHR). OBJECTIVES This study aimed at evaluating a group of subjects suffering from persistent allergic rhinitis, with BHR but with nasal symptoms only, to investigate the type and intensity of nasal symptoms, nasal and bronchial airflow, and BHR grade during the pollen season. METHODS One hundred and twenty one polysensitized rhinitics were investigated. Total symptom score (TSS) was assessed in all patients. Rhinomanometry, spirometry and methacholine bronchial challenge were performed in all patients. RESULTS 65 (53.7%) patients had impaired FEF 25-75 values. TSS correlated with nasal airflow (P<0.001) and BHR grade (P<0.001). Nasal airflow correlated with FEF 25-75 values (P<0.05) and BHR (P<0.001). FEF 25-75 values correlated with FEV(1) levels (P<0.003), BHR grade (P<0.001), and nasal obstruction symptom (P<0.05). Severe BHR correlated with FEV(1) (P<0.05) and FEF 25-75 (P<0.03) values, nasal airflow (P<0.05) and nasal symptoms (P<0.001). CONCLUSIONS This study evidences that early bronchial impairment is frequently detectable in patients with persistent allergic rhinitis and BHR. Moreover, nasal function is strictly related with bronchial calibre and BHR grade. Therefore, careful evaluation of lower airways should be investigated in all rhinitics as suggested by the ARIA document.

Abstract
BACKGROUND Allergic rhinitis and asthma are frequently associated and are characterized by TH2-dependent inflammation. Nasal and bronchial obstruction largely depend on allergic inflammation. OBJECTIVE To evaluate the relationships among nasal eosinophil counts, interleukin 4 (IL-4) and interferon-gamma (IFN-gamma) levels, nasal airflow, and forced expiratory volume in 1 second (FEV1) in patients with perennial allergic rhinitis and asthma. METHODS Eight men and 7 women (mean +/- SD age, 24.8 +/- 4.7 years) with perennial allergic rhinitis and asthma were evaluated. All 15 patients had a moderate-to-severe grade of nasal obstruction. Total symptom score, rhinomanometry, nasal lavage, nasal scraping, and spirometry were evaluated in all patients. Eosinophils were counted using conventional staining; IL-4 and IFN-gamma levels were measured by immunoassay in fluids recovered from nasal lavage. RESULTS Significant positive relationships were demonstrated between eosinophil infiltration and IL-4 levels, nasal airflow and IFN-gamma levels, FEV1 and IFN-gamma levels, and nasal airflow and FEV1 (P < .001 for all). Significant negative relationships were demonstrated between eosinophil infiltration and IFN-gamma levels, IL-4 and IFN-gamma levels, eosinophil infiltration and nasal airflow, IL-4 values and nasal airflow, nasal eosinophil counts and FEV1, and IL-4 values and FEV1 (P < .001 for all). CONCLUSIONS There is a close association between TH2 cytokines and eosinophil infiltration in the nose. There is also clear evidence concerning the relationships among eosinophil infiltration, IL-4 and IFN-gamma levels, and nasal airflow. Nasal eosinophil, IL-4, and IFN-gamma levels correlate with FEV1. Finally, nasal airflow is related to FEV1. These findings constitute the first evidence of a relationship between TH2-related nasal inflammation and nasal and bronchial airflow in patients with perennial allergic rhinitis and asthma.

Abstract
PURPOSE OF REVIEW For the present article we collected and reviewed the more relevant experimental results concerning the asthma-rhinitis link in allergic diseases, published since January 2002. RECENT FINDINGS During the last 2 years, particular attention has been devoted to the behaviour of the immune response in the two compartments of the airways. The recent experimental data, mainly obtained with specific nasal or bronchial allergen challenges, have confirmed that the link between the nose and the bronchi is bidirectional, and that a systemic cross-talk occurs. Furthermore, the pathogenic role of paranasal sinus infections in respiratory allergy has been better elucidated. It was shown that, in sinusitis, a T helper type 2 polarization exists, which can be reverted by proper therapy. On the other hand, despite the abundant experimental evidence, our view of the united airways is still not complete, and several points need to be developed. SUMMARY The new findings on the asthma-rhinitis link have confirmed the current pathogenic view of respiratory allergy. These findings have important implications from a therapeutic point of view, and therefore encourage and promote the search for novel integrated treatment strategies.

Abstract
UNLABELLED We previously demonstrated in a group of patients with perennial allergic rhinitis alone, impairment of spirometric parameters and high percentage of bronchial hyperreactivity (BHR). Thus, the present study aimed at evaluating a group of subjects suffering from seasonal allergic rhinitis alone to investigate the presence of spirometric impairment and BHR both during and outside the pollen season. METHODS One-hundred rhinitics sensitized to pollen allergens only were evaluated during and outside the pollen season. Spirometry and methacholine bronchial challenge were performed. RESULTS Four rhinitics showed impaired values of FEV1 without referred symptoms of asthma during the pollen season. FEF 25-75 values were impaired in 17 rhinitics during the pollen season and in 11 rhinitics outside the pollen season (P<0.05). Fifty-four patients showed positive methacholine bronchial challenge both during and outside the pollen season. PD20/FEV1 methacholine was lower during the pollen season than outside (P<0.05). In BHR positive patients, reduced values of FVC (P<0.05), FEV1 (P<0.05), and FEF 25-75 (P<0.01) were significantly demonstrated in comparison with BHR negative rhinitics. There was a relationship between BHR degree and FEF 25-75 values only during the pollen season (P<0.001). CONCLUSIONS This study evidences that an impairment of spirometric parameters may be observed also in patients with seasonal allergic rhinitis alone during the pollen season. A high percentage of these patients had BHR. A close relationship between upper and lower airways is confirmed also in the model of pollen allergy. Thus, a careful evaluation of lower airways should be performed also in those patients with seasonal allergic rhinitis alone.

Abstract
BACKGROUND Allergic rhinitis (AR) and asthma are frequently associated and characterized by a Th2-dependent inflammation. Nasal and bronchial obstruction may be objectively measured. OBJECTIVE The aim of this study was to evaluate the relationships among upper and lower airway function and nasal inflammation in subjects with seasonal allergic rhinitis (SAR) and asthma. METHODS Twenty out-patients (12 males and eight females, mean age: 23.4+3.6 years) with SAR and asthma were evaluated during the pollen season. All of them showed a moderate-severe grade of nasal obstruction. Total symptom score, rhinomanometry, spirometry, nasal lavage, and nasal scraping were obtained in all subjects. Eosinophils were counted by conventional staining; IL-4 and IFN-gamma were measured by immunoassay on fluids recovered from nasal lavage. RESULTS Functional parameters, i.e. nasal airflow and forced expiratory volume in 1 s (FEV(1)), were correlated with nasal eosinophils (R(2)>0.83, P<0.001). Inflammatory parameters, i.e. eosinophils were correlated with immunological parameters, i.e. IL-4 and IFN-gamma levels (R(2)=0.93, P<0.001). Nasal symptoms were correlated with nasal airflow (rho=-0.71, P< or =0.01) and eosinophils (rho=0.72, P<0.01). Nasal airflow was correlated with FEV(1) (r=0.89, P<0.0001). CONCLUSIONS This study demonstrates the close connection between Th2 cytokines and eosinophil infiltration in the nose. There is also clear evidence concerning the relationships between eosinophils infiltration and cytokines levels. Nasal eosinophils can be regarded as the most important predictors of upper and lower airway functions. These findings constitute first evidence of a relationship among nasal Th2-related inflammation and nasal and bronchial airflow in patients with SAR and asthma.

Abstract
BACKGROUND: We previously demonstrated in a group of patients with perennial allergic rhinitis alone impairment of spirometric parameters and high percentage of subjects with bronchial hyperreactivity (BHR). The present study aimed at evaluating a group of polysensitized subjects suffering from allergic rhinitis alone to investigate the presence of spirometric impairment and BHR during the pollen season. METHODS: One hundred rhinitics sensitized both to pollen and perennial allergens were evaluated during the pollen season. Spirometry and methacholine bronchial challenge were performed. RESULTS: Six rhinitics showed impaired values of FEV1 without referred symptoms of asthma. FEF 25-75 values were impaired in 28 rhinitics. Sixty-six patients showed positive methacholine bronchial challenge. FEF 25-75 values were impaired only in BHR positive patients (p < 0.001). A significant difference was observed both for FEV1 (p < 0.05) and FEF 25-75 (p < 0.001) considering BHR severity. CONCLUSIONS: This study evidences that an impairment of spirometric parameters may be observed in polysensitized patients with allergic rhinitis alone during the pollen season. A high percentage of these patients had BHR. A close relationship between upper and lower airways is confirmed.
