    Marine algae have been utilized in food as well as medicine products for a variety of purposes. The purpose of this study was to determine whether an ethanol extract of Polyopes affinis (P.affinis) can inhibit the pathogenesis of T helper 2 (Th2)-mediated allergen-induced airway inflammation in a murine model of asthma. Mice that were sensitized and challenged with ovalbumin (OVA) evidenced typical asthmatic reactions such as the following: an increase in the number of eosinophils in the bronchoalveolar lavage (BAL) fluid; a marked influx of inflammatory cells into the lung around blood vessels and airways as well as the narrowing of the airway luminal; the development of airway hyperresponsiveness (AHR); the presence of pulmonary Th2 cytokines; and the presence of allergen-specific immunoglobulin E (IgE) in the serum. The successive intraperitoneal administration of P. affinis ethanolic extracts before the last airway OVA-challenge resulted in a significant inhibition of all asthmatic reactions. These data suggest that P. affinis ethanolic extracts possess therapeutic potential for the treatment of pulmonary allergic disorders such as allergic asthma.

    Until recently the prevalence of asthma in Sweden was assessed to be 2-3 per cent. An increase in the prevalence of asthma and allergic rhinitis was noted among new conscripts undergoing health work-ups prior to military service with the most marked increase in northern Sweden, were 5 per cent of conscripts were reported to have asthma. In southern Sweden the prevalence remained about 2 per cent. More recent questionnaire studies in mid- and southern Sweden have reported similar rates of respiratory symptoms and use of anti-asthmatic drugs as in northern Sweden, suggesting that there may be no difference in asthma prevalence between the north and the south of the country. The exact prevalence of allergic diseases among Swedish adults is still not clear, but 40 per cent of adults in northern Sweden report that they often have wheezing in the chest, attacks of breathlessness, longstanding cough or sputum production. In questionnaire studies among children about 40 per cent of respondents have reported that they had asthma, allergic rhinitis or other type of hypersensitivity. The absence of generally accepted diagnostic criteria for asthma and allergic disorders in epidemiological studies makes comparison of prevalence difficult. It is thus not possible to be sure that the prevalence of asthma and allergic disorders in Sweden has recently increased. Risk factors for the development of asthma and allergic disorders are under study in Sweden. Several studies report an association in children between urban living and allergic disorders.

    Diagnosis early in life, sensitization, asthma endotypes, monitoring of disease and treatment progression are key motivations for the exploration of biomarkers for allergic rhinitis and allergic asthma. The number of genes related to allergic rhinitis and allergic asthma increases steadily; however, prognostic genes have not yet entered clinical application. We hypothesize that the combination of multiple genes may generate biomarkers with prognostic potential. The current review attempts to group more than 161 different potential biomarkers involved in respiratory inflammation to pave the way for future classifiers. The potential biomarkers are categorized into either epithelial or infiltrate-derived or mixed origin, epithelial biomarkers. Furthermore, surface markers were grouped into cell-type-specific categories. The current literature provides multiple biomarkers for potential asthma endotypes that are related to T-cell phenotypes such as Th1, Th2, Th9, Th17, Th22 and Tregs and their lead cytokines. Eosinophilic and neutrophilic asthma endotypes are also classified by epithelium-derived CCL-26 and osteopontin, respectively. There are currently about 20 epithelium-derived biomarkers exclusively derived from epithelium, which are likely to innovate biomarker panels as they are easy to sample. This article systematically reviews and categorizes genes and collects current evidence that may promote these biomarkers to become part of allergic rhinitis or allergic asthma classifiers with high prognostic value.

    There is increasing evidence that environmental changes are involved in the sharp increase in asthma incidence, as well as with other immune-mediated diseases. This increase matches the introduction of modern life advances such as antibiotics and caesarean sections. Several epidemiological studies provide convincing evidence that a lack of exposure to microbes early in life is associated with later development of allergic asthma. In addition, animal studies have shown that early life modulation of the intestinal microbiota with antibiotics has profound effects in the immune cellular mechanisms that lead to asthma. By describing some of the most relevant human and animal studies in this field, we explore the concept that significant perturbations of the intestinal and perhaps the lung microbiota are a cause of allergic asthma.

    To evaluate the antiallergic effects of oral benzaldehyde in a murine model of allergic asthma and rhinitis, we divided 20 female BALB/c mice aged 8-10 weeks into nonallergic (intraperitoneally sensitized and intranasally challenged to normal saline), allergic (intraperitoneally sensitized and intranasally challenged to ovalbumin), and 200- and 400-mg/kg benzaldehyde (allergic but treated) groups. The number of nose-scratching events in 10 min, levels of total and ovalbumin-specific IgE in serum, differential counts of inflammatory cells in bronchoalveolar lavage (BAL) fluid, titers of Th2 cytokines (IL-4, IL-5, IL-13) in BAL fluid, histopathologic findings of lung and nasal tissues, and expressions of proteins involved in apoptosis (Bcl-2, Bax, caspase-3), inflammation (COX-2), antioxidation (extracellular SOD, HO-1), and hypoxia (HIF-1α, VEGF) in lung tissue were evaluated. The treated mice had significantly fewer nose-scratching events, less inflammatory cell infiltration in lung and nasal tissues, and lower HIF-1α and VEGF expressions in lung tissue than the allergic group. The number of eosinophils and neutrophils and Th2 cytokine titers in BAL fluid significantly decreased after the treatment (Pbenzaldehyde exerts antiallergic effects in murine allergic asthma and rhinitis, possibly through inhibition of HIF-1α and VEGF.

    @@ Allergic diseases of the airway, which include seasonal rhinitis, chronic perennial rhinitis and asthma, are recognized as inflammatory disorders of the airway mucosa,1-3 but differ in the location of the inflammatory reaction and clinical manifestations of the disease. Asthma and allergic rhinitis frequently coexist in the same patient and are thought to share common predisposing genetic factors which interact with the environmental influences. Both diseases have increased in prevalence over recent decades4,5 particularly in westernized countries. This increase has been largely attributed to environmental factors such as exposure to aerial pollutants,4,6 and early life events, including the degree of exposure to infectious agents which might affect IgE production,5,7 since there has been insufficient time for a significant change in the gene pool.

    The prevalence of allergic respiratory diseases such as bronchial asthma has increased in recent years, especially in industrialized countries. A change in the genetic predisposition is an unlikely cause of the increase in allergic diseases because genetic changes in a population require several generations. Consequently, this increase may be explained by changes in environmental factors, including indoor and outdoor air pollution. Over the past two decades, there has been increasing interest in studies of air pollution and its effects on human health. Although the role played by outdoor pollutants in allergic sensitization of the airways has yet to be clarified, a body of evidence suggests that urbanization, with its high levels of vehicle emissions, and a westernized lifestyle are linked to the rising frequency of respiratory allergic diseases observed in most industrialized countries, and there is considerable evidence that asthmatic persons are at increased risk of developing asthma exacerbations with exposure to ozone, nitrogen dioxide, sulphur dioxide and inhalable particulate matter. However, it is not easy to evaluate the impact of air pollution on the timing of asthma exacerbations and on the prevalence of asthma in general. As concentrations of airborne allergens and air pollutants are frequently increased contemporaneously, an enhanced IgE-mediated response to aeroallergens and enhanced airway inflammation could account for the increasing frequency of allergic respiratory allergy and bronchial asthma. Pollinosis is frequently used to study the interrelationship between air pollution and respiratory allergy. Climatic factors (temperature, wind speed, humidity, thunderstorms, etc) can affect both components (biological and chemical) of this interaction. By attaching to the surface of pollen grains and of plant-derived particles of paucimicronic size, pollutants could modify not only the morphology of these antigen-carrying agents but also their allergenic

In a cross-sectional study, 95 asthmatic children (75 allergics and 20 nonallergics were included in the study. Demographic, clinical, and familial history were compared between two groups. There was no significant differences between variables like sex, age of onset (p=0.75, severity (p=0.70, and family history among the two groups (p=0.42. Patients with allergic asthma were significantly older than those with non- allergic asthma (11.28 ± 3.19 and 9.75 ± 2.35 years, respectively, p=0.02. The controversy lingers over the presence of a completely distinct phenotype of non-atopic asthma in children.

    Rhinitis and rhinosinusitis (with/without polyposis), either allergic or non-allergic, represent a major medical problem. Their associated comorbidities and relationship with family history have so far been poorly investigated. We assessed these aspects in a large population of patients suffering from rhinosinusal diseases. Clinical history, nasal cytology, allergy testing and direct nasal examination were performed in all patients referred for rhinitis/rhinosinusitis. Fibre optic nasal endoscopy, CT scan and nasal challenge were used for diagnosis, when indicated. A total of 455 patients (60.7% male, age range 4-84 years) were studied; 108 (23.7%) had allergic rhinitis, 128 (28.1%) rhinosinusitis with polyposis, 107 (23.5%) non-allergic rhinitis (negative skin test); 112 patients had associated allergic and non-allergic rhinitis, the majority with eosinophilia. There was a significant association between non-allergic rhinitis and family history of nasal polyposis (OR = 4.45; 95%CI = 1.70-11.61; p = 0.0019), whereas this association was no longer present when allergic rhinitis was also included. Asthma was equally frequent in non-allergic and allergic rhinitis, but more frequent in patients with polyposis. Aspirin sensitivity was more frequent in nasal polyposis, independent of the allergic (p = 0.03) or non-allergic (p = 0.01) nature of rhinitis. Nasal polyposis is significantly associated with asthma and positive family history of asthma, partially independent of the allergic aetiology of rhinitis.

    Airborne hexavalent chromate, Cr(VI), has been identified by the Environmental Protection Agency as a possible health threat in urban areas, due to the carcinogenic potential of some of its forms. Particulate chromates are produced in many different industrial settings, with high levels of aerosolized forms historically documented. Along with an increased risk of lung cancer, a high incidence of allergic asthma has been reported in workers exposed to certain inhaled particulate Cr(VI) compounds. However, a direct causal association between Cr(VI) and allergic asthma has not been established. We recently showed that inhaled particulate Cr(VI) induces an innate neutrophilic inflammatory response in BALB/c mice. In the current studies we investigated how the inflammation induced by inhaled particulate Cr(VI) might alter the pathology of an allergic asthmatic response. We used a well-established mouse model of allergic asthma. Groups of ovalbumin protein (OVA)-primed mice were challenged either with OVA alone, or with a combination of OVA and particulate zinc chromate, and various parameters associated with asthmatic responses were measured. Co-exposure to particulate Cr(VI) and OVA mediated a mixed form of asthma in which both eosinophils and neutrophils are present in airways, tissue pathology is markedly exacerbated, and airway hyperresponsiveness is significantly increased. Taken together these findings suggest that inhalation of particulate forms of Cr(VI) may augment the severity of ongoing allergic asthma, as well as alter its phenotype. Such findings may have implications for asthmatics in settings in which airborne particulate Cr(VI) compounds are present at high levels. -- Highlights: ► Allergic asthma correlated with exposure to certain inhaled particulate chromates. ► Direct causal association between Cr(VI) and allergic asthma not established. ► Cr exacerbated pathology and airway hyperresponsiveness in an OVA-challenged mouse. ► Particulate Cr

    BackgroundAllergic sensitization to fungi has been associated with asthma severity. As a result, it has been largely assumed that the contribution of fungi to allergic disease is mediated through their potent antigenicity.ObjectiveWe sought to determine the mechanism by which fungi affect asthma development and severity.MethodsWe integrated epidemiologic and experimental asthma models to explore the effect of fungal exposure on asthma development and severity.ResultsWe report that fungal exposure enhances allergen-driven TH2 responses, promoting severe allergic asthma. This effect is independent of fungal sensitization and can be reconstituted with β-glucan and abrogated by neutralization of IL-17A. Furthermore, this severe asthma is resistant to steroids and characterized by mixed TH2 and TH17 responses, including IL-13+IL-17+CD4+ double-producing effector T cells. Steroid resistance is dependent on fungus-induced TH17 responses because steroid sensitivity was restored in IL-17rc−/− mice. Similarly, in children with asthma, fungal exposure was associated with increased serum IL-17A levels and asthma severity.ConclusionOur data demonstrate that fungi are potent immunomodulators and have powerful effects on asthma independent of their potential to act as antigens. Furthermore, our results provide a strong rationale for combination treatment strategies targeting IL-17A for this subgroup of fungus-exposed patients with difficult-to-treat asthma. To describe th

    Full Text Available Abstract Background Offspring of asthmatic mothers have increased risk of developing asthma, based on human epidemiologic data and experimental animal models. The objective of this study was to determine whether maternal allergy at non-pulmonary sites can increase asthma risk in offspring. Methods BALB/c female mice received 2 topical applications of vehicle, dinitrochlorobenzene, or toluene diisocyanate before mating with untreated males. Dinitrochlorobenzene is a skin-sensitizer only and known to induce a Th1 response, while toluene diisocyanate is both a skin and respiratory sensitizer that causes a Th2 response. Both cause allergic contact dermatitis. Offspring underwent an intentionally suboptimal protocol of allergen sensitization and aerosol challenge, followed by evaluation of airway hyperresponsiveness, allergic airway inflammation, and cytokine production. Mothers were tested for allergic airway disease, evidence of dermatitis, cellularity of the draining lymph nodes, and systemic cytokine levels. The role of interleukin-4 was also explored using interleukin-4 deficient mice. Results Offspring of toluene diisocyanate but not dinitrochlorobenzene-treated mothers developed an asthmatic phenotype following allergen sensitization and challenge, seen as increased Penh values, airway inflammation, bronchoalveolar lavage total cell counts and eosinophilia, and Th2 cytokine imbalance in the lung. Toluene diisocyanate treated interleukin-4 deficient mothers were able to transfer asthma risk to offspring. Mothers in both experimental groups developed allergic contact dermatitis, but not allergic airway disease. Conclusion Maternal non-respiratory allergy (Th2-skewed dermatitis caused by toluene diisocyanate can result in the maternal transmission of asthma risk in mice.

    The distributions of asthma, hay fever and eczema were examined in the first degree relatives of 516 asthmatics grouped according to atopic status, history of hay fever/eczema and history of asthma provoked by pollens, dust or animals. The prevalences of both asthma and eczema in relatives were strongly correlated with the presence of hay fever/eczema in probands and to a lesser extent with their atopic status. The prevalence of hay fever in relatives was strongly correlated with both the presence of hay fever/eczema and the degree of atopy in probands. In contrast, allergic provocation of asthma in probands did not influence the prevalences of asthma, hay fever or eczema. These findings are consistent with the hypothesis that there is an increased risk of asthma in relatives of atopic asthmatics which may arise from the enhanced susceptibility to asthma of individuals who inherit both a predisposition to asthma and a predisposition to atopy.

    Full Text Available BACKGROUND: In the preschool period, allergic rhinitis (AR is infrequent and thus under-diagnosed. However, recent works have highlighted the occurrence of AR in toddlers although the causes of AR in this young population remain unknown. The objective of this study was to identify determinants of AR in young children with asthma. METHODS: We carried out a case-control study of 227 children with active asthma and enrolled in the Trousseau Asthma Program. AR and other allergic diseases (asthma, food allergy and eczema were diagnosed by medical doctors using standardized questionnaires. Parental history of AR and asthma, biological markers of atopy (total IgE, blood eosinophilia, allergic sensitization towards food and aeroallergens and environmental parameters were also collected. RESULTS: Forty one of the children (18.1% had AR. By univariate logistic regression analysis, AR was mainly associated with peanut sensitization (OR = 6.75; p = 0.002; food allergy (OR = 4.31; p = 0.026; mold exposure (OR = 3.81 p<0.01 and parental history of AR (OR = 1.42; p = 0.046. Due to the strong link between food allergy and peanut sensitization three models of multivariate logistic regression were performed and confirmed that AR is associated with peanut sensitization but also food allergy and mold exposure. A random forest analysis was also performed to explain AR. The results reinforced the logistic analysis that peanut sensitization and mold exposure were the principal determinants of AR. CONCLUSIONS & CLINICAL RELEVANCE: These results stress the importance of investigating AR in young children with asthma to potentially diagnose a particularly severe allergic asthmatic phenotype. Moreover, these data evoke the hypothesis that peanut could be an aeroallergen.

    Allergic diseases have become a major public health problem in industrialized countries, justifying the development of prevention programs. A review of the literature on allergens and atopic symptoms, age of primary sensitization and other factors associated with allergic diseases development is presented and is followed by a discussion on prevention measures. The most recent physiopathological and immunological data indicate that persistent asthma and allergic diseases in adults may be associated with events in early childhood. The parallel increase in autoimmune and allergic diseases has been correlated with regulatory mechanism defects, contradicting the previous theory that involved a predominantly Th1 or Th2 pathway. The primary prevention of asthma and allergic diseases thus appear to be somewhat utopian. Indeed based on recent results, the risk of developing allergies appears to be related to modern "clean" lyfestyles. Secondary prevention is probably necessary, possibly through specific immunotherapy. Tertiary prevention must also be considered. Passive smoking must be prevented as it can alter the development of the respiratory system and promote allergen sensitization. Randomized, controlled, prospective studies are needed to evaluate the efficacy of the preventive measures.

    Full Text Available Acupuncture has an historical significance and currently its’ use and esteem are growing in modern medicine. Acupuncture points, or acu points are specific foci along lineer meridians or channels on skin surface. Recently, they are stimulated with needles, ultrasound, palpation, light and electric resistance. Acupuncture is based on influencing of acu points. However there is no standard definition or clinical approach to acupuncture. Needling techniques and forms of stimulation vary widely across patients and practitioners. During the last 50 years, acupuncture techniques have been put into practice in different regions of the world by most medical specialties, including allergic diseases. In this review, effects of acupuncture on immune system, and the possible mechanisms in allergic diseases are discussed. According to published data, effectiveness of acupuncture in allergic diseases seems to be related with the activation of hypothalamic-pituitary-adrenal axis, which is resulted in increased steroid production. Evidence from large randomised trials, including follow-up measurements of markers of inflammation, could be obtained to prove the immunologic effects of acupuncture.

    The allergen challenge has evolved, in less than 150 years, from a crude tool used to document the etiology of allergen-induced disease to a well-controlled tool used today to investigate the pathophysiology and pharmacotherapy of asthma. Highlights of the authors’ involvement with the allergen challenge include confirmation of the immunoglobulin E-dependence of the late asthmatic response, importance of (nonallergic) airway hyper-responsiveness as a determinant of the airway response to allergen, identification of allergen-induced increase in airway hyper-responsiveness, documentation of beta2-agonist-induced increase in airway response to allergen (including eosinophilic inflammation), advances in understanding the pathophysiology and kinetics of allergen-induced airway responses, and development of a muticentre clinical trial group devoted to using the allergen challenge for investigating promising new therapeutic strategies for asthma.

    Full Text Available Allergic asthma is characterized by bronchial hyperresponsiveness, a defective barrier function, and eosinophilic lower airway inflammation in response to allergens. The inflammation is dominated by Th2 cells and IgE molecules and supplemented with Th17 cells in severe asthma. In contrast, in healthy individuals, allergen-specific IgA and IgG4 molecules are found but no IgE, and their T cells fail to proliferate in response to allergens, probably because of the development of regulatory processes that actively suppress responses to allergens. The presence of allergen-specific secretory IgA has drawn little attention so far, although a few epidemiological studies point at a reverse association between IgA levels and the incidence of allergic airway disease. This review highlights the latest literature on the role of mucosal IgA in protection against allergic airway disease, the mechanisms described to induce secretory IgA, and the role of (mucosal dendritic cells in this process. Finally, we discuss how this information can be used to translate into the development of new therapies for allergic diseases based on, or supplemented with, IgA boosting strategies.

    Asthma and atopic disorders are the most common chronic diseases in the developed countries. Knowledge of the risk factors for these disorders may facilitate the development of preventive strategies aimed at reducing prevalence rates. To investigate the risk factors for asthma and allergic diseases in a large number of adults who are the parents of children in the National Asthma Campaign Manchester Asthma and Allergy Study. All pregnant women and their partners attending "Booking" antenatal clinics were invited to take part in the study. Questionnaire data were collected including the history of asthma and other atopic diseases, pet ownership and smoking habits, and skin prick tests were performed. The prevalence of atopy and the risk factors for asthma and allergic disorders were investigated in all subjects who completed the questionnaire and underwent skin testing. Statistical analysis was carried out using logistic regression. Initially, risk factors were assessed by univariate analysis to see how each potential explanatory variable affected the probability of having allergic disease. Variables were then tested in a forward stepwise multivariate analysis. In 5687 adult subjects there was a very high (48.2%) prevalence of atopy, and 9.7% of subjects had a diagnosis of asthma. In a multivariate regression analysis sensitization to dust mite, cat, dog and mixed grasses were all independently associated with asthma. The odds ratios for current asthma increased with the increasing number of positive skin tests (any two allergens - OR 4.3, 95% CI 3.3-5.5; any three allergens - OR 7.0 95% CI 5.3-9.3; all four allergens - OR 10.4, 95% CI 7.7-14; P Dog ownership (OR 1.31, 95% CI 1.10-1.57; P = 0.003) and current smoking (OR 1.36, 95% CI 1.15-1.62; P = 0.0004) were significantly and directly associated with "asthma ever". Thirteen per cent of participants reported a history of eczema. In the multivariate analysis the strongest independent associate of eczema was

    Full Text Available Background. Asthma and allergic rhinitis are highly prevalent conditions that cause major illness worldwide. This study aimed to assess the association between allergic rhinitis and asthma control in Peruvian school children. Methods. A cross-sectional study was conducted among 256 children with asthma recruited in 5 schools from Lima and Callao cities. The outcome was asthma control assessed by the asthma control test. A score test for trend of odds was used to evaluate the association between allergic rhinitis severity and the prevalence of inadequate asthma control. A generalized linear regression model was used to estimate the adjusted prevalence ratios of inadequate asthma control. Results. Allergic rhinitis was present in 66.4% of the population with asthma. The trend analysis showed a positive association between allergic rhinitis and the probability of inadequate asthma control (. It was associated with an increased prevalence of inadequate asthma control, with adjusted prevalence ratios of 1.53 (95% confidence interval: 1.19−1.98. Conclusion. This study indicates that allergic rhinitis is associated with an inadequate level of asthma control, giving support to the recommendation of evaluating rhinitis to improve asthma control in children.

    Studies were undertaken to determine whether differences in serum cytokine balances could be involved in the pathogenesis of allergic and in non-allergic asthma. At this propose, interferon-gamma, tumor necrosis factor-alpha, interleukin-2, interleukin-4, interleukin-6, and interleukin-10 were measured by enzimoimmunoassay. The analysis was performed on 24 allergic and 24 non-allergic asthmatic patients and 16 healthy subjects. IFN-gamma and TNF-alpha, included into the type 1 cytokines, appeared significantly increased in the allergic with respect to the non-allergic asthmatic patients (p = 0.01) and (p < 0.001) respectively, while IL-10, which belongs to the type 2 cytokines, was significantly increased in the non-allergic asthmatic (p < 0.001). The IL-6 analysis did not show any significant difference in either of the study group. The most interesting finding was the high serum IL-10 values detected in intrinsic asthmatic patients, which in turn, suggests that this cytokine could participate in the regulation of different immunological features that occurs in non-allergic asthma, and maybe it could indicate a higher stimulated state of cells in this type of asthma. The data presented in this report show a different cytokine profile in serum from allergic and non-allergic asthmatic patients and denote a stronger prevalence of type 2 cytokines in intrinsic asthma.

  15. FcgammaRIIb inhibits allergic lung inflammation in a murine model of allergic asthma.

    Full Text Available Allergic asthma is characterized by airway eosinophilia, increased mucin production and allergen-specific IgE. Fc gamma receptor IIb (FcgammaRIIb, an inhibitory IgG receptor, has recently emerged as a negative regulator of allergic diseases like anaphylaxis and allergic rhinitis. However, no studies to date have evaluated its role in allergic asthma. Our main objective was to study the role of FcgammaRIIb in allergic lung inflammation. We used a murine model of allergic airway inflammation. Inflammation was quantified by BAL inflammatory cells and airway mucin production. FcgammaRIIb expression was measured by qPCR and flow cytometry and the cytokines were quantified by ELISA. Compared to wild type animals, FcgammaRIIb deficient mice mount a vigorous allergic lung inflammation characterized by increased bronchoalveolar lavage fluid cellularity, eosinophilia and mucin content upon ragweed extract (RWE challenge. RWE challenge in sensitized mice upregulated FcgammaRIIb in the lungs. Disruption of IFN-gamma gene abrogated this upregulation. Treatment of naïve mice with the Th1-inducing agent CpG DNA increased FcgammaRIIb expression in the lungs. Furthermore, treatment of sensitized mice with CpG DNA prior to RWE challenge induced greater upregulation of FcgammaRIIb than RWE challenge alone. These observations indicated that RWE challenge upregulated FcgammaRIIb in the lungs by IFN-gamma- and Th1-dependent mechanisms. RWE challenge upregulated FcgammaRIIb on pulmonary CD14+/MHC II+ mononuclear cells and CD11c+ cells. FcgammaRIIb deficient mice also exhibited an exaggerated RWE-specific IgE response upon sensitization when compared to wild type mice. We propose that FcgammaRIIb physiologically regulates allergic airway inflammation by two mechanisms: 1 allergen challenge mediates upregulation of FcgammaRIIb on pulmonary CD14+/MHC II+ mononuclear cells and CD11c+ cells by an IFN-gamma dependent mechanism; and 2 by attenuating the allergen specific Ig

    Allergic asthma has a global prevalence, morbidity, and mortality. Many environmental factors, such as pollutants and allergens, are highly relevant to allergic asthma. The most important pathological symptom of allergic asthma is airway inflammation. Accordingly, the unique role of reactive oxygen species (ROS) had been identified as a main reason for this respiratory inflammation. Many studies have shown that inhalation of different allergens can promote ROS generation. Recent studies have demonstrated that several pro-inflammatory mediators are responsible for the development of allergic asthma. Among these mediators, endogenous or exogenous ROS are responsible for the airway inflammation of allergic asthma. Furthermore, several inflammatory cells induce ROS and allergic asthma development. Airway inflammation, airway hyper-responsiveness, tissue injury, and remodeling can be induced by excessive ROS production in animal models. Based on investigations of allergic asthma and ROS formation mechanisms, we have identified several novel anti-inflammatory therapeutic treatments. This review describes the recent data linking ROS to the pathogenesis of allergic asthma. PMID:28203435

    Full Text Available Objective: It would not be right to link the reasons for the worldwide increase in incidents of childhood obesity and those of allergic diseases only to genetics. Obesity, asthma and allergic diseases can be prevented through the consumption of healthy food. In this study, children’s eating habits, obesity, asthma and other allergic diseases were intended to determine their relationship with each other. Methods: In a high socioeconomic level school in Mardin , asthma and allergic diseases of children aged between 7-15 were diagnosed by a doctor, and their eating habits between meals, food types they buy from the school canteen and their family data were determined by survey. Results: Obesity and overweight was higher with the boys than the girls. 21.7% of the girls , 13.4% of the boys had allergic diseases. Allergic diseases were remarkably frequent with girls (p<0.0001. 1.6% of the girls and 2.3% of the boys had asthma. Allergic diseases was higher with the overweight and obese groups. Children who had breakfast regularly had significantly less tendency to be overweight or obese (p<0.00001. Conclusion: Genetic predisposition is the most important factor in emerging obesity and allergic diseases. However, it is not possible to explain the worldwide increase of obesity, allergic diseases and asthma only by genetics. The part played by complex dietary factors should be explained for obesity, asthma and other allergic diseases and understood through a multidisciplinary approach.

    Most of the healthcare costs associated with asthma relate to emergency department visits and hospitalizations because of acute exacerbations of underlying chronic disease. Development of appropriate animal models of acute exacerbations of asthma is a necessary prerequisite for understanding pathophysiological mechanisms and assessing potential novel therapeutic approaches. Most such models have been developed using mice. Relatively few mouse models attempt to simulate the acute-on-chronic disease that characterizes human asthma exacerbations. Instead, many reported models involve relatively short-term challenge with an antigen to which animals are sensitized, followed closely by an unrelated triggering agent, so are better described as models of potentiation of acute allergic inflammation. Triggers for experimental models of asthma exacerbations include (i) challenge with high levels of the sensitizing allergen (ii) infection by viruses or fungi, or challenge with components of these microorganisms (iii) exposure to environmental pollutants. In this review, we examine the strengths and weaknesses of published mouse models, their application for investigation of novel treatments and potential future developments.

    Full Text Available BACKGROUND: The link between upper and lower airways in patients with both asthma and allergic rhinitis is still poorly understood. As the biological complexity of these disorders can be captured by gene expression profiling we hypothesized that the clinical expression of rhinitis and/or asthma is related to differential gene expression between upper and lower airways epithelium. OBJECTIVE: Defining gene expression profiles of primary nasal and bronchial epithelial cells from the same individuals and examining the impact of allergic rhinitis with and without concomitant allergic asthma on expression profiles. METHODS: This cross-sectional study included 18 subjects (6 allergic asthma and allergic rhinitis; 6 allergic rhinitis; 6 healthy controls. The estimated false discovery rate comparing 6 subjects per group was approximately 5%. RNA was extracted from isolated and cultured epithelial cells from bronchial brushings and nasal biopsies, and analyzed by microarray (Affymetrix U133+ PM Genechip Array. Data were analysed using R and Bioconductor Limma package. For gene ontology GeneSpring GX12 was used. RESULTS: The study was successfully completed by 17 subjects (6 allergic asthma and allergic rhinitis; 5 allergic rhinitis; 6 healthy controls. Using correction for multiple testing, 1988 genes were differentially expressed between healthy lower and upper airway epithelium, whereas in allergic rhinitis with or without asthma this was only 40 and 301 genes, respectively. Genes influenced by allergic rhinitis with or without asthma were linked to lung development, remodeling, regulation of peptidases and normal epithelial barrier functions. CONCLUSIONS: Differences in epithelial gene expression between the upper and lower airway epithelium, as observed in healthy subjects, largely disappear in patients with allergic rhinitis with or without asthma, whilst new differences emerge. The present data identify several pathways and genes that might be

However, tropical pollens, such as those of Palmae, have seldom been investigated compared with the specific immunotherapy studies done on hyperallergenic birch, olive, and ragweed pollens. Although poly(lactic-co-glycolic acid (PLGA has been extensively applied as a biodegradable polymer in medical devices, it has rarely been utilized as a vaccine adjuvant to prevent and treat allergic disease. In this study, we investigated the immunotherapeutic effects of recombinant Caryota mitis profilin (rCmP-loaded PLGA nanoparticles and the underlying mechanisms involved. Methods: A mouse model of allergenic asthma was established for specific immunotherapy using rCmP-loaded PLGA nanoparticles as the adjuvant. The model was evaluated by determining airway hyperresponsiveness and levels of serum-specific antibodies (IgE, IgG, and IgG2a and cytokines, and observing histologic sections of lung tissue. Results: The rCmP-loaded PLGA nanoparticles effectively inhibited generation of specific IgE and secretion of the Th2 cytokine interleukin-4, facilitated generation of specific IgG2a and secretion of the Th1 cytokine interferon-gamma, converted the Th2 response to Th1, and evidently alleviated allergic symptoms. Conclusion: PLGA functions more appropriately as a specific immunotherapy adjuvant for allergen vaccines than does conventional Al(OH3 due to its superior efficacy, longer potency, and markedly fewer side effects. The rCmP-loaded PLGA nanoparticles developed

    Specific allergen immunotherapy represents the only curative treatment of allergy. No studies have evaluated its efficacy in feline allergic asthma. We hypothesized that an abbreviated course of immunotherapy (rush immunotherapy, RIT) would blunt eosinophilic airways inflammation in experimental feline asthma induced with Bermuda grass allergen (BGA). The 6-month study included asthmatic-RIT treated cats; asthmatic-no RIT treated cats; and non-asthmatic cats. RIT involved increasing parenteral doses (20-200 microg) of BGA over 2 days. Numbers of eosinophils in bronchoalveolar lavage fluid (BALF), serum and BALF immunoglobulins, lymphocyte blastogenesis assays, and cytokines in blood and BALF were evaluated. BALF eosinophils decreased (P=0.048) only in asthmatic-RIT treated cats (baseline 1.1 x 10(6); Month 6, 2.4 x 10(5)). Serum BGA-specific IgG was higher (Peosinophilic airways inflammation in cats with experimental asthma. The mechanism of RIT may involve changes in allergen-specific immunoglobulins, induction of hyporesponsive lymphocytes, or alteration of cytokine profiles.

    Among the major allergic pulmonary disorders are bronchial asthma, extrinsic allergic alveolitis, allergic aspergillosis and berylliosis. Asthma is diagnosed on the basis of clinical symptoms (wheezing, respiratory distress, tight chest, coughing) and lung function tests possibly supplemented by allergic and provocative testing. Asthma treatment is differentiated into long-term medication and as-required medication. Specific immunotherapy is considered the sole causal therapy. Extrinsic allergic alveolitis is work- or hobby-related (farmer's/cheese worker's/bird-fancier's lung) and manifests as diffuse pneumonitis with dyspnea, coughing and fever. For the diagnosis, the antigen provocative test in particular plays a major role. In the main, treatment comprises strict avoidance of allergens. The diagnosis of allergic pulmonary aspergillosis is based on the history, clinical findings, skin tests, serology and radiography. Treatment is stage-related by means of immunosuppressive agents. In terms of radiographic and pulmonary function findings, berylliosis is similar to sarcoidosis. Here, too, immunosuppressive agents are to the fore.

    Objective To investigate the link between the polymorphism of -109 and Glu237 in the high-affinity IgE receptor β (FcεRⅠβ) gene and susceptibilty to allergic asthma in a Chinese population.Method Blood samples from 216 allergic asthma patients and 198 age- and sex-matched controls were studied. A-109C/T and a coding variant Glu237Gly in FcεRⅠβ were detected with polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP).Results The genotype frequencies were 0.403 for -109T/T, 0.491 for -109T/C and 0.106 for -109C/C in allergic asthma in a Chinese population. No significant difference in the distribution of -109C/T polymorphism was found between allergic asthma subjects and healthy controls, however, homozygosity for the -109T allele was associated with increased total plasma IgE levels in subjects with allergic asthma (F=4.020,P<0.05). The allele frequency of Gly237 in the patients and control was 0.236 and 0.136 respectively. There was a significant association between the Gly/Gly genotype and allergic asthma. Among allergic asthma patients Gly237 was significantly associated with high IgE levels.Conclusions These results suggest that the Gly237 variant of the FcεRⅠβ gene is involved in the development of allergic asthma. The-109C/T and Glu237Gly polymorphisms are two of the genetic factor identified thus far, which affect total plasma IgE levels of allergic asthma patients in a Chinese population.

    Notch is a pleiotropic signaling family that has been implicated in pathogenesis of allergic airway diseases; however, the distinct function of individual Notch ligands remains elusive. We investigated whether Notch ligands, Jagged1 and DLL4, exert differential effects in OVA-induced allergic asthma. We found that whilst Jagged1 inhibition mitigated Th2-dominated airway inflammation, blockage of DLL4 aggravated the Th2-mediated asthma phenotypes. Additionally, Jagged1 signaling blockage enhanced IL-17 production and neutrophilic airway infiltration. In vitro, exogenous Jagged1 induced Th2-skewed responses, whereas augmented DLL4 signaling displayed a dual role by promoting expansion of both Tregs and Th17. In vivo, DLL4 blockage impaired Treg differentiation which plausibly resulted in exaggerated asthma phenotypes. On the contrary, administration of DLL4-expressing antigen-presenting cells promoted endogenous Treg expansion and ameliorated the allergic responses. Therefore, whilst Jagged1 induces Th2-skewed inflammation, DLL4 elicits an essential self-regulatory mechanism via Treg-mediated pathway that counterbalances Jagged1-induced Th2 responses and facilitates resolution of the airway inflammation to restore homeostasis. These findings uncover a disparate function of Jagged1 and DLL4 in allergic airway diseases, hinting feasibility of Notch ligand-specific targeting in therapy of allergic airway diseases.

    Increased asthma severity is not only associated with enhanced recurrent hospitalization and mortality but also with higher social costs. Several cases of asthma are atopic in nature, with the trigger for acute asthma attacks and chronic worsening of inflammation being allergens inducing an immune, IgE mediated response. Anti-inflammatory treatments are effective for most of asthma patients, but there are subjects whose disease is incompletely controlled by inhaled or systemic corticosteroids and these patients account for about 50% of the healthcare costs of asthma. Omalizumab is a biological engineered, humanized recombinant monoclonal anti-IgE antibody developed for the treatment of allergic diseases and with clear efficacy in adolescent and adult patients with severe allergic asthma. The anti-IgE antibody inhibits IgE functions blocking free serum IgE and inhibiting their binding to cellular receptors. By reducing serum IgE levels and IgE receptor expression on inflammatory cells in the context of allergic cascade, omalizumab has demonstrated to be a very useful treatment of atopic asthma, improving quality of life of patients with severe persistent allergic asthma that is inadequately controlled by currently available asthma medications. Several trials have demonstrated that this therapy is well tolerated and significantly improves symptoms and disease control, reducing asthma exacerbations and the need to use high dosage of inhaled corticosteroids.

    The aim of this study was to assess whether the association with social class differed between allergic rhinitis and asthma and whether these associations have changed over time. The Swedish Military Service Conscription Register was linked to two other national registers for 1,247,038 male conscripts in successive cohorts born between 1952 and 1977. The percentage of asthma cases associated with allergic rhinitis was 15% in the oldest cohort and 44% in the youngest cohort. Low socio-economic status (SES) was associated with an increased risk (assessed as odds ratio) of asthma without allergic rhinitis (1.14, 95% confidence interval (CI) 1.11-1.17) but a slightly reduced risk of asthma with allergic rhinitis (0.96, 95% CI 0.93-1.00). The risk of allergic rhinitis was 0.84, 95% CI 0.82-0.85. A positive interaction between SES and year of birth occurred in all three conditions. Low SES was related to a reduced risk of asthma with allergic rhinitis in the earliest cohort (0.72, 95% CI 0.53-0.82) but a slightly increased risk in the most recent cohort (1.07, 95% CI 1.01-1.14). In conclusion, the role of social class has changed over time. The steepest increase in asthma and allergic rhinitis occurred in conscripts with a low socio-economic status.

    Full Text Available Abstract Background There is conflicting evidence that traffic-related air pollution is a risk factor for allergic conditions. Few studies have investigated this in adults. In adults, a high proportion of asthma, rhinitis and eczema is triggered by non-allergic factors. We investigated traffic as a risk factor for allergic versus non-allergic asthma and rhinitis, and eczema, in adults. A questionnaire from 2000 (n = 9319, 18–77 years provided individual data about disease outcome and self-reported traffic exposure. Additional exposure assessments were obtained using Geographical Informations Systems (GIS. Residential addresses were linked to the national Swedish Road Database and to a pollutant database with modelled annual means of NOx (Nitrogen Oxids. Results Living within 100 m from a road with a traffic intensity of >10 cars/min (24 hour mean was associated with prevalence of current asthma reported to be triggered by allergic factors (OR = 1.83, 95% CI = 1.23–2.72 and with allergic rhinitis (OR = 1.30, 95%CI = (1.05–1.61. No relation was seen with asthma or rhinitis triggered by other factors. Living within 100 m of a road with >10 cars/min was also associated with hand-eczema during the last 12 months (OR = 1.63, 95% CI = 1.19–2.23, but not with allergic eczema or diagnosed hand-eczema. Consistent results were seen using self-reported traffic, but the associations with NOx were less consistent. Conclusion Exposure to traffic was associated with a higher prevalence of allergic asthma and allergic rhinitis, but not with asthma or rhinitis triggered by non-allergic factors. This difference was suggested by the overall pattern, but only clear using GIS-measured traffic intensity as a proxy for traffic exposure. An association was also found with hand-eczema during the last 12 months. We suggest that asthma and rhinitis should not be treated as homogenous groups when estimating effects from traffic in adults.

    Chronic inflammation in the lung has long been linked to the pathogenesis of asthma. Central to this airway inflammation is a T-cell response to allergens, with Th2 cytokines driving the differentiation, survival and function of the major inflammatory cells involved in the allergic cascade. PI3Kδ (phosphoinositide 3-kinase δ) is a lipid kinase, expressed predominantly in leucocytes, where it plays a critical role in immune receptor signalling. A selective PI3Kδ inhibitor is predicted to block T-cell activation in the lung, reducing the production of pro-inflammatory Th2 cytokines. PI3Kδ is also involved in B-cell and mast cell activation. Therefore the inhibition of PI3Kδ should dampen down the inflammatory cascade involved in the asthmatic response through a wide breadth of pharmacology. Current anti-inflammatory therapies, which are based on corticosteroids, are effective in controlling inflammation in mild asthmatics, but moderate/severe asthmatic patients remain poorly controlled, experiencing recurrent exacerbations. Corticosteroids have no effect on mast cell degranulation and do not act directly on B-cells, so, overall, a PI3Kδ inhibitor has the potential to deliver improvements in onset of action, efficacy and reduced exacerbations in moderate/severe asthmatics. Additionally, PI3Kδ inhibition is expected to block effects of Th17 cells, which are increasingly implicated in steroid-insensitive asthma.

    Full Text Available Abstract Background The association between sensitizations and severity of allergic diseases is controversial. Objective This study was to investigate the association between severity of asthma and rhinitis and degree of specific allergic sensitization in allergic patients in China. Method A cross-sectional survey was performed in 6304 patients with asthma and/or rhinitis from 4 regions of China. Patients completed a standardized questionnaire documenting their respiratory and allergic symptoms, their impact on sleep, daily activities, school and work. They also underwent skin prick tests with 13 common aeroallergens. Among the recruited subjects, 2268 provided blood samples for serum measurement of specific IgE (sIgE against 16 common aeroallergens. Results Significantly higher percentage of patients with moderate-severe intermittent rhinitis were sensitized to outdoor allergens while percentage of patients sensitized to indoor allergens was increased with increasing severity of asthma. Moderate-severe intermittent rhinitis was associated with the skin wheal size and the level of sIgE to Artemisia vulgaris and Ambrosia artemisifolia (p Dermatophagoides (D. pteronyssinus and D. farinae (p Conclusions Artemisia vulgaris and Ambrosia artemisifolia sensitizations are associated with the severity of intermittent rhinitis and D. pteronyssinus and D. farinae sensitizations are associated with increasing severity of asthma in China. Increase in number of allergens the patients are sensitized to may also increase the severity of rhinitis and asthma.

    Maternal asthma during pregnancy adversely affects pregnancy outcomes but identification of the cause/s, and the ability to evaluate interventions, is limited by the lack of an appropriate animal model. We therefore aimed to characterise maternal lung and cardiovascular responses and fetal-placental growth and lung surfactant levels in a sheep model of allergic asthma. Immune and airway functions were studied in singleton-bearing ewes, either sensitised before pregnancy to house dust mite (HDM, allergic, n = 7) or non-allergic (control, n = 5), and subjected to repeated airway challenges with HDM (allergic group) or saline (control group) throughout gestation. Maternal lung, fetal and placental phenotypes were characterised at 140 ± 1 days gestational age (term, ∼147 days). The eosinophil influx into lungs was greater after HDM challenge in allergic ewes than after saline challenge in control ewes before mating and in late gestation. Airway resistance increased throughout pregnancy in allergic but not control ewes, consistent with increased airway smooth muscle in allergic ewes. Maternal allergic asthma decreased relative fetal weight (-12%) and altered placental phenotype to a more mature form. Expression of surfactant protein B mRNA was 48% lower in fetuses from allergic ewes than controls, with a similar trend for surfactant protein D. Thus, allergic asthma in pregnant sheep modifies placental phenotype, and inhibits fetal growth and lung development consistent with observations from human pregnancies. Preconceptional allergen sensitisation and repeated airway challenges in pregnant sheep therefore provides an animal model to identify mechanisms of altered fetal development and adverse pregnancy outcomes caused by maternal asthma in pregnancy.

    Histamine is an important mediator in the pathogenesis of asthma. Variation in genes along the histamine production, response, and degradation pathway may be important in predicting response to antihistamines. We hypothesize that differences exist among single-nucleotide polymorphisms (SNPs) in genes of the histamine pathway between children with allergic versus nonallergic asthma. Children (7-18 yr of age; n = 202) with asthma were classified as allergic or nonallergic based on allergy skin testing. Genotyping was performed to detect known SNPs (n = 10) among genes (HDC, HNMT, ABP1, HRH1, and HRH4) within the histamine pathway. Chi square tests and Cochran-Armitage Trend were used to identify associations between genetic variants and allergic or nonallergic asthma. Significance was determined by P histamine pathway may be associated with an allergic versus nonallergic asthma phenotype. Further studies are needed to determine the functional significance of identified SNPs and their impact on antihistamine response in patients with asthma and allergic disease.

    l-theanine, a water-soluble amino acid isolated from green tea (Camellia sinensis), has anti-inflammatory activity, antioxidative properties, and hepatoprotective effects. However, the anti-allergic effect of l-theanine and its underlying molecular mechanisms have not been elucidated. In this study, we investigated the protective effects of l-theanine on asthmatic responses, particularly airway inflammation and oxidative stress modulation in an ovalbumin (OVA)-induced murine model of asthma. Treatment with l-theanine dramatically attenuated the extensive trafficking of inflammatory cells into bronchoalveolar lavage fluid (BALF). Histological studies revealed that l-theanine significantly inhibited OVA-induced mucus production and inflammatory cell infiltration in the respiratory tract and blood vessels. l-theanine administration also significantly decreased the production of IgE, monocyte chemoattractant protein-1 (MCP-1), interleukin (IL)-4, IL-5, IL-13, tumor necrosis factor-alpha (TNF-α), and interferon-gamma in BALF. The lung weight decreased with l-theanine administration. l-theanine also markedly attenuated the OVA-induced generation of reactive oxygen species and the activation of nuclear factor kappa B (NF-κB) and matrix metalloprotease-9 in BALF. Moreover, l-theanine reduced the TNF-α-induced NF-κB activation in A549 cells. Together, these results suggest that l-theanine alleviates airway inflammation in asthma, which likely occurs via the oxidative stress-responsive NF-κB pathway, highlighting its potential as a useful therapeutic agent for asthma management.

    We aimed to evaluate the effect of chronic hypergravity in a mouse model of allergic asthma and rhinitis. Forty BALB/c mice were divided as: group A (n = 10, control) sensitized and challenged with saline, group B (n = 10, asthma) challenged by intraperitoneal and intranasal ovalbumin (OVA) to induce allergic asthma and rhinitis, and groups C (n = 10, asthma/rotatory control) and D (n = 10, asthma/hypergravity) exposed to 4 weeks of rotation with normogravity (1G) or hypergravity (5G) during induction of asthma/rhinitis. Group D showed significantly decreased eosinophils, neutrophils, and lymphocytes in their BAL fluid compared with groups B and C (p lung homogenate, the expression of IL-1β was significantly upregulated (p lung parenchyma and turbinate, and the thickness of respiratory epithelium was significantly reduced in group D (p < 0.05). The expression of Bcl-2 and heme oxygenase-1 were significantly downregulated, Bax and extracellular dismutase significantly upregulated in Group D. Therefore, chronic hypergravity could have a hormetic effect for allergic asthma and rhinitis via regulation of genes involved in antioxidative and proapoptotic pathways. It is possible that we could use hypergravity machinery for treating allergic respiratory disorders.

    Full Text Available Diarmuid M. McNicholl, Liam G. HeaneyRegional Respiratory Centre, Belfast City Hospital, Belfast, UKIntroduction: Asthma is a chronic inflammatory airways disease associated with reversible airflow obstruction and bronchial hyperresponsiveness. Asthma is prevalent worldwide and results in significant morbidity, mortality, and healthcare costs, the majority of which arise from those with severe disease. Omalizumab is a monoclonal antibody to immunoglobulin E (IgE that has been developed for the treatment of severe persistent allergic (IgE mediated asthma.Aims: The aim of this review is to evaluate the available clinical evidence on omalizumab to determine the role it has to play in the treatment of persistent allergic asthma.Evidence review: There is clear evidence to show that omalizumab is effective in reducing the rate of asthma exacerbations, inhaled corticosteroid dose, and the need for rescue medication in patients with allergic asthma. Clinical data indicate beneficial effects on patient-reported symptoms and perceived quality of life, as well as a reduction in unscheduled healthcare visits. There is little evidence to suggest omalizumab may enhance lung function or reduce the requirement for oral corticosteroids. Omalizumab has a favorable safety profile, although anaphylaxis has occurred. A study in children showed similar results to those achieved in adults and adolescents, with fewer asthma exacerbations and school days missed. Omalizumab may be cost effective in patients when used as add-on therapy to inhaled corticosteroids and long-acting beta2 agonists (LABA.Place in therapy: Omalizumab is an effective add-on therapy to inhaled corticosteroids and LABAs in adults and adolescents with severe persistent allergic asthma. Currently there is insufficient evidence to support the use of omalizumab in children.  Key words: allergic asthma, omalizumab, immunoglobulin E, evidence

    Study of the chronobiology of allergic rhinitis (AR) and bronchial asthma (BA) and the chronopharmacology and chronotherapy of the medications used in their treatment began five decades ago. AR is an inflammatory disease of the upper airway tissue with hypersensitivity to specific environmental antigens, resulting in further local inflammation, vasomotor changes, and mucus hypersecretion. Symptoms include sneezing, nasal congestion, and runny and itchy nose. Approximately 25% of children and 40% of adults in USA are affected by AR during one or more seasons of the year. The manifestation and severity of AR symptoms exhibit prominent 24-h variation; in most persons they are worse overnight or early in the morning and often comprise nighttime sleep, resulting in poor daytime quality of life, compromised school and work performance, and irritability and moodiness. BA is also an inflammatory medical condition of the lower airways characterized by hypersensitivity to specific environmental antigens, resulting in greater local inflammation as well as bronchoconstriction, vasomotor change, and mucus hypersecretion. In USA an estimated 6.5 million children and 15.7 million adults have BA. The onset and worsening of BA are signaled by chest wheeze and/or croupy cough and difficult and labored breathing. Like AR, BA is primarily a nighttime medical condition. AR is treated with H1-antagonist, decongestant, and anti-inflammatory (glucocorticoid and leukotriene receptor antagonist and modifier) medications. Only H1-antagonist AR medications have been studied for their chronopharmacology and potential chronotherapy. BA is treated with some of the same medications and also theophylline and beta2-agonists. The chronopharmacology and chronotherapy of many classes of BA medications have been explored. This article reviews the rather extensive knowledge of the chronobiology of AR and BA and the chronopharmacology and chronotherapy of the various medications used in their treatment.

    Full Text Available Allergic rhinitis and asthma are both chronic heterogeneous disorders, with an overlapping epidemiology of prevalence, health care costs and social costs in quality of life. Both are inflammatory disorders with a similar pathophysiology, and both share some treatment approaches. However, each disorder has an array of treatments used separately in controlling these atopic disorders, from inhaled corticosteroids, beta2-agonists and antihistamines to newer monoclonal antibody-based treatments. The present article reviews the shared components of allergic rhinitis and asthma, and examines recent evidence supporting antileukotrienes as effective agents in reducing the symptoms of both diseases.

    Type 1 diabetes (T1D) and allergic asthma are immune-mediated diseases. Pattern recognition receptors are proteins expressed by cells in the immune system to identify microbial pathogens and endogenous ligands. Toll-like receptors (TLRs) and CD14 are members of this family and could represent a molecular link between microbial infections and immune-mediated diseases. Diverging hypotheses regarding whether there exists a common or inverse genetic etiology behind these immune-mediated diseases have been presented. We aimed to test whether there exist common or inverse associations between polymorphisms in the pattern recognition receptors TLR2, TLR4 and CD14 and T1D and allergic asthma. Eighteen single nucleotide polymorphisms (SNPs) were genotyped in TLR2 (2), TLR4 (12) and CD14 (4) in 700 T1D children, 357 nuclear families with T1D children and 796 children from the 'Environment and Childhood Asthma' study. Allele and haplotype frequencies were analyzed in relation to diseases and in addition transmission disequilibrium test analyses were performed in the family material. Both T1D and allergic asthma were significantly associated with the TLR2 rs3804100 T allele and further associated with the haplotype including this SNP, possibly representing a susceptibility locus common for the two diseases. Neither TLR4 nor CD14 were associated with T1D or allergic asthma.

    2006-11-01

    Full Text Available Abstract Background Allergic rhinitis and asthma are conditions of airway inflammation that often coexist. Discussion In susceptible individuals, exposure of the nose and lungs to allergen elicits early phase and late phase responses. Contact with antigen by mast cells results in their degranulation, the release of selected mediators, and the subsequent recruitment of other inflammatory cell phenotypes. Additional proinflammatory mediators are released, including histamine, prostaglandins, cysteinyl leukotrienes, proteases, and a variety of cytokines, chemokines, and growth factors. Nasal biopsies in allergic rhinitis demonstrate accumulations of mast cells, eosinophils, and basophils in the epithelium and accumulations of eosinophils in the deeper subepithelium (that is, lamina propria. Examination of bronchial tissue, even in mild asthma, shows lymphocytic inflammation enriched by eosinophils. In severe asthma, the predominant pattern of inflammation changes, with increases in the numbers of neutrophils and, in many, an extension of the changes to involve smaller airways (that is, bronchioli. Structural alterations (that is, remodeling of bronchi in mild asthma include epithelial fragility and thickening of its reticular basement membrane. With increasing severity of asthma there may be increases in airway smooth muscle mass, vascularity, interstitial collagen, and mucus-secreting glands. Remodeling in the nose is less extensive than that of the lower airways, but the epithelial reticular basement membrane may be slightly but significantly thickened. Conclusion Inflammation is a key feature of both allergic rhinitis and asthma. There are therefore potential benefits for application of anti-inflammatory strategies that target both these anatomic sites.

    Full Text Available BACKGROUND: Evidence for an association between traffic-related air pollution and allergic disease is inconsistent, possibly because the adverse effects may be limited to susceptible subgroups and these have not been identified. This study examined children in the Childhood Asthma Prevention Study (CAPS, potentially susceptible to air pollution effects because of a family history of asthma. METHODS: We examined cross-sectional associations at age eight years between road density within 75 m and 50 m of home address weighted by road type (traffic density, as a proxy for traffic-related air pollution, on the following allergic and respiratory outcomes: skin prick tests (SPTs, total and specific serum IgE, pre- and post-bronchodilator lung function, airway hyperresponsiveness, exhaled NO, and reported asthma and rhinitis. RESULTS: Weighted road density was positively associated with allergic sensitisation and allergic rhinitis. Adjusted relative risk (RR for house dust mite (HDM positive SPT was 1.25 (95% CI: 1.06-1.48, for detectable house dust mite-specific IgE was 1.19 (95% CI: 1.01-1.41 and for allergic rhinitis was 1.30 (95% CI: 1.03-1.63 per 100 m local road or 33.3 m motorway within 50 m of home. Associations were also seen with small decrements of peak and mid-expiratory flows and increased risk of asthma, current wheeze and rhinitis in atopic children. CONCLUSION: Associations between road density and allergic disease were found in a potentially susceptible subgroup of children at high risk of developing atopy and asthma.

    Full Text Available Abstract Asthma and rhinitis are often co-morbid conditions. As rhinitis often precedes asthma it is possible that effective treatment of allergic rhinitis may reduce asthma progression. The aim of our study is to investigate history of allergic rhinitis as a risk factor for asthma and the potential effect of allergen immunotherapy in attenuating the incidence of asthma. Hospital-referred non-asthmatic adults, aged 18–40 years between 1990 and 1991, were retrospectively followed up until January and April 2000. At the end of follow up, available subjects were clinically examined for asthma diagnosis and history of allergen specific immunotherapy, second-hand smoking and the presence of pets in the household. A total of 436 non-asthmatic adults (332 subjects with allergic rhinitis and 104 with no allergic rhinitis nor history of atopy were available for final analyses. The highest OR (odds ratio associated with a diagnosis of asthma at the end of follow-up was for the diagnosis of allergic rhinitis at baseline (OR, 7.8; 95%CI, 3.1–20.0 in the model containing the covariates of rhinitis diagnosis, sex, second-hand smoke exposure, presence of pets at home, family history of allergic disorders, sensitization to Parietaria judaica; grass pollen; house dust mites; Olea europea: orchard; perennial rye; and cat allergens. Female sex, sensitization to Parietaria judaica and the presence of pets in the home were also significantly predictive of new onset asthma in the same model. Treatment with allergen immunotherapy was significantly and inversely related to the development of new onset asthma (OR, 0.53; 95%CI, 0.32–0.86. In the present study we found that allergic rhinitis is an important independent risk factor for asthma. Moreover, treatment with allergen immunotherapy lowers the risk of the development of new asthma cases in adults with allergic rhinitis.

    Asthma and extrinsic allergic alveolitis (EAA) remain prevalent respiratory diseases and the cause of a significant disease burden. This article reviews the recent occupational and environmental causes described for these conditions. Even over the limited time spam addressed by this article, novel agents and new data relating to already suggested causes have been described. Various types of work tasks or exposures are described that appear to cause both asthma and EAA. Isocyanates, the best example of dual potential to cause asthma and EAA are discussed, as is the new understanding of the role metal-working fluids play when causing respiratory diseases.

    Full Text Available Accumulated evidence suggests a relationship between specific allergic processes, such as atopic eczema in children, and an aberrant fecal microbiota. However, little is known about the complete microbiota profile of adult individuals suffering from asthma. We determined the fecal microbiota in 21 adult patients suffering allergic asthma (age 39.43 ± 10.98 years old and compare it with the fecal microbiota of 22 healthy controls (age 39.29 ± 9.21 years old using culture independent techniques. An Ion-Torrent 16S rRNA gene-based amplification and sequencing protocol was used to determine the fecal microbiota profile of the individuals. Sequence microbiota analysis showed that the microbial alpha-diversity was not significantly different between healthy and allergic individuals and no clear clustering of the samples was obtained using an unsupervised principal component analysis. However, the analysis of specific bacterial groups allowed us to detect significantly lower levels of bifidobacteria in patients with long-term asthma. Also, in allergic individuals the Bifidobacterium adolescentis species prevailed within the bifidobacterial population. The reduction in the levels on bifidobacteria in patients with long-term asthma suggests a new target in allergy research and opens possibilities for the therapeutic modulation of the gut microbiota in this group of patients.

    Full Text Available Allergen-specific immunotherapy is aimed at modifying the natural history of allergy by inducing tolerance to the causative allergen. In its traditional, subcutaneous form, immunotherapy has complete evidence of efficacy in allergic asthma. However, subcutaneous immunotherapy (SCIT has a major flaw in side effects, and especially in possible anaphylactic reactions, and this prompted the search for safer ways of administration of allergen extracts. Sublingual immunotherapy (SLIT has met such need while maintaining a clinical efficacy comparable to SCIT. In fact, the safety profile, as outlined by a systematic revision of the available literature, was substantially free from serious systemic reactions. A number of meta-analyses clearly showed that SLIT is effective in allergic rhinitis by significantly reducing the clinical symptoms and the use of anti-allergic drugs, while the efficacy in allergic asthma is still debated, with some meta-analyses showing clear effectiveness but other giving contrasting results. Besides the efficacy on symptoms, the preventive activity and the cost-effectiveness are important outcomes of SLIT in asthma. The needs to meet include more data on efficacy in house dust mite asthma, optimal techniques of administration and, as previously done with SCIT, introduction of adjuvants able to enhance the immunologic response and use of recombinant allergens.

    Allergic asthma is a disease characterized by persistent allergen-driven airway inflammation, remodeling and airway hyperresponsiveness (AHR). CD4+ T-cells, in particular T-helper type 2 (Th2) cells, play a critical role in orchestrating the disease process through the release of cytokines like IL-4

    Full Text Available Asthma is the result of chronic inflammation of the airways which subsequently results in airway hyper-responsiveness and airflow obstruction. It has been shown that an elicited expression of acidic mammalian chitinase (AMCase may be involved in the pathogenesis of asthma. Our recent study has demonstrated that the specific suppression of elevated AMCase leads to reduced eosinophilia and Th2-mediated immune responses in an ovalbumin (OVA-sensitized mouse model of allergic asthma. In the current study, we show that the elicited expression of AMCase in the lung tissues of both ovalbumin- and Der P2-induced allergic asthma mouse models. The effects of allergic mediated molecules on AMCase expression were evaluated by utilizing promoter assay in the lung cells. In fact, the exposure of chitin, a polymerized sugar and the fundamental component of the major allergen mite and several of the inflammatory mediators, showed significant enhancement on AMCase expression. Such obtained results contribute to the basis of developing a promising therapeutic strategy for asthma by silencing AMCase expression.

  20. Estrogen signaling modulates allergic inflammation and contributes to sex differences in asthma.

    Full Text Available Asthma is a chronic airway inflammatory disease that afflicts approximately 300 million people worldwide. It is characterized by airway constriction that leads to wheezing, coughing, and shortness of breath. The most common treatments are corticosteroids and β2-adrenergic receptor antagonists, which target inflammation and airway smooth muscle constriction, respectively. The incidence and severity of asthma is greater in women than in men, and women are more prone to develop corticosteroid-resistant or hard-to-treat asthma. Puberty, menstruation, pregnancy, menopause, and oral contraceptives are known to contribute to disease outcome in women, potentially suggesting a role for estrogen and other hormones impacting allergic inflammation. Currently, the mechanisms underlying these sex differences are poorly understood, although the effect of sex hormones, such as estrogen, on allergic inflammation is gaining interest. Asthma presents as a heterogeneous disease. In typical Th2-type allergic asthma, interleukin-4 and interleukin-13 predominate, driving IgE production and recruitment of eosinophils into the lungs. Chronic Th2-inflammation in the lung results in structural changes and activation of multiple immune cell types, leading to a deterioration of lung function over time. Most immune cells express estrogen receptors (ERα, ERβ, or the membrane-bound G-protein-coupled estrogen receptor to varying degrees and can respond to the hormone. Together these receptors have demonstrated the capacity to regulate a spectrum of immune functions, including adhesion, migration, survival, wound healing, and antibody and cytokine production. This review will cover the current understanding of estrogen signaling in allergic inflammation and discuss how this signaling may contribute to sex differences in asthma and allergy.

    Asthma is characterized by airway inflammation, mucus secretion, remodeling and hyperresponsiveness (AHR). Recent research has established the bronchodilatory effect of bitter taste receptor (TAS2R) agonists in various models. Comprehensive pre-clinical studies aimed at establishing effectiveness of TAS2R agonists in disease models are lacking. Here we aimed to determine the effect of TAS2R agonists on features of asthma. Further, we elucidated a mechanism by which TAS2R agonists mitigate features of asthma. Asthma was induced in mice using intranasal house dust mite or aerosol ova-albumin challenge, and chloroquine or quinine were tested in both prophylactic and treatment models. Allergen challenge resulted in airway inflammation as evidenced by increased immune cells infiltration and release of cytokines and chemokines in the lungs, which were significantly attenuated in TAS2R agonists treated mice. TAS2R agonists attenuated features of airway remodeling including smooth muscle mass, extracellular matrix deposition and pro-fibrotic signaling, and also prevented mucus accumulation and development of AHR in mice. Mechanistic studies using human neutrophils demonstrated that inhibition of immune cell chemotaxis is a key mechanism by which TAS2R agonists blocked allergic airway inflammation and exerted anti-asthma effects. Our comprehensive studies establish the effectiveness of TAS2R agonists in mitigating multiple features of allergic asthma.

    Full Text Available Background: Allergen immunotherapy involves the administration of gradually increasing quantities of specific allergens to patients with IgE-mediated conditions until a dose is reached that is effective in reducing disease severity from natural exposure. This study evaluated the clinical efficacy of immunotherapy with extracts of common aeroallergens North-East of Iran in asthma and allergic rhinitis. Material and Methods: In this prospective study 156 cases were chosen randomley. The mean age of patients was 37 years (range 5-65 years. The patients with mild to moderate asthma and allergic rhinitis and history of atopy were selected for immunotherapy when they showed no effective response to medical treatment.Immunotherapy materials were made from common aeroallergens in north-eastern region of Iran by Dome Hollister US company. Immunotherapy schedule for injection of the extract with vial dilution of 1:10000pg was one injection every week for ten weeks and one injection with dilution of 1:1000pg every other week for the other ten weeks and one injection monthly from dilution of 1:100pg for two years. Results: One hundred twenty (77% of cases had allergic rhinitis 29(18.5% cases had allergic asthma and 7(4.5% cases were mixed. Mean age of patients were 37 years old. 48(30.8% cases were male. Analysis of efficacy of treatment showed that immunotherapy significantlyimproved the signs and symptoms of all the groups. In allergic rhinitis group 84(70% cases completely improved, 22(18.4% patients moderately responded and no response to immunotherapy was observed in 14(11.6% patients. In allergic asthma group, 22(75% cases completely improved 4(13.6% cases moderately responded and no response to immunotherapy was detected in 3(11.4% cases. In mixed group, 3(42.8% cases completely improved, 3(42.8% cases moderately responded and no response was observed in 1(14.4% case.

    Obesity and overweight have been associated with an increased risk of asthma in children as well as adults. The association between atopy and body mass index (BMI) is less clear. It has also been suggested that the link between a high BMI and asthma could be a recent phenomenon. The objective of this study was to assess whether the association with BMI differed between allergic rhinoconjunctivitis and asthma and if these associations have changed over time. The Swedish Military Service Conscription Register was linked to the Register of the Total Population and the Population and Housing Censuses. Asthma (with and without allergic rhinoconjunctivitis) and allergic rhinoconjunctivitis at conscription were analysed in relation to BMI for 1,247,038 male conscripts in successive cohorts born between 1952 and 1977. Obesity was associated with asthma without allergic rhinoconjunctivitis, adjusted OR 1.53 (95% CI 1.43-1.63), and with asthma with allergic rhinoconjunctivitis, adjusted OR 1.34 (95% CI 1.20-1.50), but not with allergic rhinoconjunctivitis, OR 1.00 (95% CI 0.97-1.03) after multivariate analyses with adjustments for confounders. The odds ratios were similar in three successive cohorts (conscripts born in 1952-1961, 1962-1971 and 1972-1977). Underweight was associated with a slightly increased risk for all three conditions. The increased risk of asthma in young Swedish men with obesity has remained unchanged over a period of three decades.

    In the present paper, the therapeutic effect of acupoint application of Chinese Materia Medica in thetreatment of allergic asthma was observed. The results revealed that topical application of drug-paste [mixture of pow-der of Mahuang (Herba Ephedrae), Xixin (Herba Asari), Baijiezi (Semen Sinapis Albae), etc. ] at the acupuncturepoints could improve symptoms and signs of allergic asthma patients, with the total effective rate being 69.57% ( 16/23) for the short-term effect, and 52.17% (12/23) for the long-term effect. In medication (Aminophylline) group, ofthe 25 cases of allergic asthma, 16 (64.0%) were effective after 4 weeks of treatment, while 6 (24.0%) were stilleffective that was shown by 6-months' follow up. The therapeutic effect of acupoint application group was significantlybetter than that of medication group in the long-term effect. Results also showed that no obvious interrelation betweenthe short-term therapeutic effect and the duration or the severity of the disease. Results also display that acupoint ap-plication therapy is an effective, safe and handy method with fewer side effects for asthma.

    The aims of the current study were to ascertain the prevalence of asthma and allergic rhinoconjunctivitis symptoms in Cairo, Egypt (northern Africa), and to elucidate the socioeconomic factors associated with symptom prevalence and severity. A translated and adapted version of the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was distributed to a sample of 2,645 11-15-yr-olds in state and fee-paying schools in Cairo. The overall prevalences of wheeze ever, wheeze during the last year and physician-diagnosed asthma were 26.5% (697 out of 2,631), 14.7% (379 out of 2,570) and 9.4% (246 out of 2,609), respectively. The prevalence of rhinoconjunctivitis was 15.3% (399 out of 2,616). Asthma symptoms were independently associated with attendance at a state school, parental asthma, age, history of rhinitis and owning a pet cat. Rhinoconjunctivitis was independently associated with attendance at a state school, father's education, parental history of asthma, asthma symptoms and owning a pet cat. In spite of a higher prevalence of severe asthma symptoms in state schools prevalence of physician diagnosis of asthma was the same in both school types, suggesting inequalities in access to healthcare. In conclusion, the prevalence of physician-diagnosed asthma in Cairo was 9.4%, while the prevalence of rhinoconjunctivitis was 15.3%. There is a higher prevalence and increased severity of asthma symptoms in children of lower socioeconomic groups, as defined by state school attendance in Cairo.

    Chronic inflammation with mucous metaplasia and airway remodeling are hallmarks of allergic asthma, and these outcomes have been associated with enhanced expression and activation of EGFR signaling. Here, we demonstrate enhanced expression of EGFR ligands such as amphiregulin as well as constitutive EGFR activation in cultured nasal epithelial cells from asthmatic subjects compared with nonasthmatic controls and in lung tissues of mice during house dust mite–induced (HDM-induced) allergic inflammation. EGFR activation was associated with cysteine oxidation within EGFR and the nonreceptor tyrosine kinase Src, and both amphiregulin production and oxidative EGFR activation were diminished by pharmacologic or genetic inhibition of the epithelial NADPH oxidase dual oxidase 1 (DUOX1). DUOX1 deficiency also attenuated several EGFR-dependent features of HDM-induced allergic airway inflammation, including neutrophilic inflammation, type 2 cytokine production (IL-33, IL-13), mucous metaplasia, subepithelial fibrosis, and central airway resistance. Moreover, targeted inhibition of airway DUOX1 in mice with previously established HDM-induced allergic inflammation, by intratracheal administration of DUOX1-targeted siRNA or pharmacological NADPH oxidase inhibitors, reversed most of these outcomes. Our findings indicate an important function for DUOX1 in allergic inflammation related to persistent EGFR activation and suggest that DUOX1 targeting may represent an attractive strategy in asthma management.

    Asthma is a disorder of the airways involving various inflammatory cells and mediators and characterised by bronchial hyperresponsiveness, chronic inflammation and structural alterations in the airways, also known as remodelling. IgE is an important mediator of allergic reactions and has a central role in allergic asthma pathophysiology, as it is implicated in both the early and late phase allergic response. Moreover, clinical and mechanistic evidence has lately emerged, implicating IgE in the development of airway remodelling. The use of monoclonal antibodies targeting IgE, such as omalizumab, has proven very effective in improving respiratory symptoms and quality of life, while reducing asthma exacerbations, emergency room visits and the use of systemic corticosteroids in allergic severe asthma. These effects are believed to be mainly mediated by omalizumab's inhibitory effect on the initiation and further propagation of the allergic inflammation cascade. However, there is evidence to suggest that anti-IgE treatment remains effective long after it has been discontinued. In part, these findings could be attributed to the possible ameliorating effects of anti-IgE treatment on airway remodelling. In this review, we discuss recent findings supporting the notion that anti-IgE treatment modulates the complex immune responses that manifest clinically as asthma and ameliorates airway remodelling changes often observed in allergic severe asthma phenotypes.

    Costello, R W

    2012-02-01

    BACKGROUND: Patients with asthma who have persistent symptoms despite treatment with inhaled steroids and long-acting beta agonists are considered to have severe asthma. Omalizumab is a monoclonal antibody directed against IgE, which is used as an add-on treatment for patients who have severe persistent allergic asthma. AIMS: The aim of this study was to assess the clinical benefit and healthcare utilisation of patients who responded to omalizumab therapy and to establish an overall cost implication. METHODS: This was an observational retrospective cohort study designed to investigate the effect of omalizumab on exacerbations of asthma before and after 6 months of treatment in Irish patients. RESULTS: Centres who had treated patients with severe allergic asthma for the 6 months prior and post omalizumab treatment were audited with a standardised assessment tool. Sixty-three (32 male) patients were studied. In the 6 months prior to omalizumab 41 of 63 (66%) had been hospitalised, and this fell to 15 of 63 (24%), p < 0.0001 in the 6 months after treatment was started. Hospital admissions reduced from 2.4 +\\/- 0.41 to 0.8 +\\/- 0.37 and the mean number of bed days occupied was reduced from 16.6 +\\/- 2.94 to 5.3 +\\/- 2.57 days, p < 0.001. The number of oral corticosteroid doses used fell from 3.1 +\\/- 0.27 to 1.2 +\\/- 0.17, p < 0.001. The overall cost saving per omalizumab responder patients for 6 months was 834. CONCLUSIONS: Six months therapy with omalizumab reduced the number of bed days, the number of hospitalisations and the use of oral corticosteroids compared to the 6 months prior to commencement. Despite the cost of the additional therapy there were overall savings in health costs.

    Objective To investigate CTLA4-Ig's potential role in therapy for allergic asthma by blocking B7/CD28 interactions with cytotoxic T lymphocyte antigen 4-Ig (CTLA4-Ig).Methods We divided BALB/C mice into the three groups: Sham/Sham (control), ovalbumin (OVA)/OVA and mCTLA4-Ig. Blood, bronchoalveolar lavage, histology and determination of cytokines were performed 24 hours after airway challenge. Results In the OVA/OVA group, the number of cells, the percentage of inflamed cells and the level of IL-4 in BALF were increased. Airways in our murine model for allergic asthma underwent pathological changes, which were significantly reduced after treatment with mCTLA4-Ig. Conclusion Blockage of co-stimulation with mCTLA4-Ig can inhibit allergy-specific response of T cells, and asthmatic response as well.

    In this study, the therapeutic effect of acupuncture and its effect on serum tumor necrosis factor apha (TNF-α) level was observed in 25 cases of allergic bronchial asthma patients. Acupoints used were Dazhui (GV 14),Feishu (BL 13), Dingchuan (EX-B 1), Pishu (BL 20), Tanzhong (CV 17), Shenshu (BL 23) and Fengchi (GB 20),supplemented with other acupoints according to syndrome differentiation. After 15 sessions of treatment, results showed that the total effective rate was 96 %. Before treatment, serum TNF-α activity was significantly higher than that of healthy subjects (25 cases, P < 0.01 ). After treatment, TNF-α level reduced considerably in comparison with that of pre-treatment (P< 0.05). These findings indicate that acupuncture can significantly improve allergic asthma patients' clinical symptoms and lower serum TNF-α activity.

    Full Text Available Background: Royal jelly is widely used as a health tonic, especially in Asia. Royal jelly is commonly used in cosmetics as well as in dietary supplements and beverages. Little is known, however, about the pharmacologic efficacy of topical royal jelly. Therefore, we investigated the antipruritic activity of topical royal jelly on chronic pruritus in experimental allergic contact dermatitis in mice. Materials and Methods: Hairless mice (HOS: HR-1, with chronic allergic contact dermatitis induced by 5 weeks of repeated application of 2,4,6-trinitro-1-chlorobenzene (TNCB to the entire back skin were treated topically with royal jelly (0.01% or 1% for 5 weeks after sensitization with TNCB. The effects of royal jelly on pruritus and inflammation were evaluated by measurement of scratching behavior and skin inflammation score, respectively. Results: Repeated application of TNCB to the back skin of mice elicited frequent scratching behavior immediately and 24h after challenge. Topical royal jelly (0.01% or 1% and betamethasone (0.01% significantly ameliorated this chronic pruritus throughout the experimental period. The level of nerve growth factor mRNA in back skin was increased in the mice with dermatitis and reduced by betamethasone, but not by royal jelly. Conclusion: The inhibitory effect of royal jelly on chronic pruritus may occur through different mechanisms from those of betamethasone. Topical application of royal jelly, as used in cosmetics, might be beneficial for the alleviation of chronic pruritus.

    Full Text Available Abstract Background Childhood hospitalization related to asthma remains at historically high levels, and its incidence is on the rise world-wide. Previously, we have demonstrated that aldose reductase (AR, a regulatory enzyme of polyol pathway, is a major mediator of allergen-induced asthma pathogenesis in mouse models. Here, using AR null (AR-/- mice we have investigated the effect of AR deficiency on the pathogenesis of ragweed pollen extract (RWE-induced allergic asthma in mice and also examined the efficacy of enteral administration of highly specific AR inhibitor, fidarestat. Methods The wild type (WT and AR-/- mice were sensitized and challenged with RWE to induce allergic asthma. AR inhibitor, fidarestat was administered orally. Airway hyper-responsiveness was measured in unrestrained animals using whole body plethysmography. Mucin levels and Th2 cytokine in broncho-alveolar lavage (BAL were determined using mouse anti-Muc5A/C ELISA kit and multiplex cytokine array, respectively. Eosinophils infiltration and goblet cells were assessed by H&E and periodic acid Schiff (PAS-staining of formalin-fixed, paraffin-embedded lung sections. T regulatory cells were assessed in spleen derived CD4+CD25+ T cells population. Results Deficiency of AR in mice led to significantly decreased PENH, a marker of airway hyper-responsiveness, metaplasia of airway epithelial cells and mucus hyper-secretion following RWE-challenge. This was accompanied by a dramatic decrease in infiltration of eosinophils into sub-epithelium of lung as well as in BAL and release of Th2 cytokines in response to RWE-challenge of AR-/- mice. Further, enteral administration of fidarestat significantly prevented eosinophils infiltration, airway hyper-responsiveness and also markedly increased population of T regulatory (CD4+CD25+FoxP3+ cells as compared to RWE-sensitized and challenged mice not treated with fidarestat. Conclusion Our results using AR-/- mice strongly suggest the role

    Summary: The relationship between 3 polymorphisms sites [interleulin-4 (IL-4), IL-4 receptor (IL-4R) α chain and activation-induced cytidine deaminase (AICDA)] and adult allergic asthma in Chinawas studied. By using case-control method, DNA and clinical data were obtained from allergic asth-matic patients and compared with those in the control subjects. The subjects were genotyped for theIL-4 C-589T promoter polymorphism, the IL-4R α chain Q576R and the AICDA C8408T by poly-merase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The resultsshowed that the IL-4 C-589T was not associated with adult allergic asthma in China. However, theIL-4R α chain 576R/R and AICDA 8408T/T frequency was significantly increased in allergic asthmagroup as compared with that in the control group [odd ratio (OR)= 3. 797 and 9. 127, respectively;P<0.01)] and was correlated with the increased plasma total IgE. These data suggested that theIL-4R α chain 576R/R and AICDA 8408T/T genotypes confer genetic susceptibility to adult allergicasthma in China.

    Diglycidyl ether of bisphenol A (DGEBA) epoxy resins belong to the most common causes of occupational allergic contact dermatitis. DGEBA has on rare occasions caused occupational asthma. Here we present a patient who first developed occupational allergic contact dermatitis (ACD) caused by a single accidental exposure to DGEBA. Then, on continued occupational exposure to DGEBA, the patient developed occupational asthma from DGEBA, in addition to ACD. A bronchial provocation test with DGEBA caused a 36% drop in the peak expiratory flow, reflecting a delayed type of occupational asthma. This bronchial provocation test caused a strong dermatitis of the exposed skin of the face, in accordance with airborne ACD from DGEBA.

    Obese asthma presents with inherent hyperresponsiveness to methacholine or augmented allergen-driven allergic asthma, with an even greater magnitude of methacholine hyperresponsiveness. These physiologic parameters and accompanying obese asthma symptoms can be reduced by successful weight loss, yet the underlying mechanisms remain incompletely understood. We implemented mouse models of diet-induced obesity, dietary and surgical weight loss, and environmental allergen exposure to examine the mechanisms and mediators of inherent and allergic obese asthma. We report that the methacholine hyperresponsiveness in these models of inherent obese asthma and obese allergic asthma manifests in distinct anatomical compartments but that both are amenable to interventions that induce substantial weight loss. The inherent obese asthma phenotype, with characteristic increases in distal airspace tissue resistance and tissue elastance, is associated with elevated proinflammatory cytokines that are reduced with dietary weight loss. Surprisingly, bariatric surgery-induced weight loss further elevates these cytokines while reducing methacholine responsiveness to levels similar to those in lean mice or in formerly obese mice rendered lean through dietary intervention. In contrast, the obese allergic asthma phenotype, with characteristic increases in central airway resistance, is not associated with increased adaptive immune responses, yet diet-induced weight loss reduces methacholine hyperresponsiveness without altering immunological variables. Diet-induced weight loss is effective in models of both inherent and allergic obese asthma, and our examination of the fecal microbiome revealed that the obesogenic Firmicutes/Bacteroidetes ratio was normalized after diet-induced weight loss. Our results suggest that structural, immunological, and microbiological factors contribute to the manifold presentations of obese asthma.

    Oroxylin A, a natural flavonoid isolated from the medicinal herb Scutellaria baicalensis Georgi, has been reported to have anti-inflammatory property. In this study, we aimed to investigate the protective effects and mechanism of oroxylin A on allergic inflammation in OVA-induced asthma murine model. BABL/c mice were sensitized and airway-challenged with OVA to induce asthma. Oroxylin A (15, 30, and 60 mg/kg) was administered by oral gavage 1 h before the OVA treatment on day 21 to 23. The results showed that oroxylin A attenuated OVA-induced lung histopathologic changes, airway hyperresponsiveness, and the number of inflammatory cells. Oroxylin A also inhibited the levels of IL-4, IL-5, IL-13, and OVA-specific IgE in BALF. Furthermore, oroxylin A significantly inhibited OVA-induced NF-κB activation. In conclusion, these results suggested that oroxylin A inhibited airway inflammation in OVA-induced asthma murine model by inhibiting NF-κB activation. These results suggested that oroxylin A was a potential therapeutic drug for treating allergic asthma.

    Full Text Available Maekmoondong-tang (MMDT has long been used in Asian countries to treat respiratory diseases. However, the precise mechanisms underlying its effects on asthma are unknown. This study was conducted to evaluate the protective effects of MMDT in a cockroach allergen (CKA-induced animal model of allergic asthma. After being challenged with CKA, the number of macrophages, eosinophils, neutrophils, lymphocytes, and total cells in the bronchoalveolar lavage fluid (BALF was evaluated. The Th2 specific cytokines IL-4, IL-5, and IL-13 were also analyzed in BALF along with IgE levels in serum. For histological analysis, hematoxylin and eosin (H&E staining, periodic acid-Schiff (PAS staining, and immunohistochemical staining were performed. In addition, airway hyperresponsiveness was assessed by noninvasive plethysmography. The cellular profiles and histopathologic analysis demonstrated that peribronchial and perivascular inflammatory cell infiltrates were significantly decreased in the MMDT-treated groups compared with the cockroach extract-injected (CKA groups. In addition, the IgE, IL-4, IL-5, and IL-13 levels were significantly decreased in the MMDT group. MMDT treatment also significantly attenuated airway hyperresponsiveness. These results demonstrated that MMDT significantly reduced the hallmark signs of asthma: elevated serum IgE, airway eosinophilia, airway remodeling, mucus hypersecretion, and airway hyperresponsiveness. The remarkable antiasthmatic effects of MMDT suggest its therapeutic potential in allergic asthma treatment.

    Background: Several studies highlighted a great variability, both between and within countries, in the prevalence of asthma and chronic airways diseases. Aim: To evaluate if geo-climatic variations can explain the heterogeneity in the prevalence of asthma and respiratory diseases in Italy. Methods: Between 2006 and 2010, a postal screening questionnaire on respiratory health was administered to 18,357 randomly selected subjects, aged 20–44, living in 7 centers in northern, central, and southern Italy. A random-effects meta-analysis was fitted to evaluate the between-centers heterogeneity in the prevalence of asthma, asthma-like symptoms, allergic rhinitis, and chronic bronchitis (CB). A principal component analysis (PCA) was performed to synthetize the geo-climatic information (annual mean temperature, range of temperature, annual rainfalls, global solar radiations, altitude, distance from the sea) of all the 110 Italian province capital towns. The associations between these geo-climatic components obtained with PCA and the prevalence of respiratory diseases were analyzed through meta-regression models. Results: 10,464 (57%) subjects responded to the questionnaire. There was a significant between-centers heterogeneity in the prevalence of asthma (I{sup 2} = 59.5%, p = 0.022) and CB (I{sup 2} = 60.5%, p = 0.019), but not in that of asthma-like symptoms or allergic rhinitis. Two independent geo-climatic components explaining together about 80% of the overall geo-climatic variability were identified: the first principally summarized the climatic variables; the second the topographic ones. Variations in the prevalence of asthma across centers were significantly associated with differences in the climatic component (p = 0.017), but not with differences in the topographic one. Conclusions: Our findings suggest that climate play a role in determining the between-center heterogeneity in the prevalence of asthma in Italy, with higher prevalence in dry-hot Mediterranean

    Full Text Available In 1993 the European Academy of Allergy and Clinical Immunology was the first official organization to recognize that sublingual administration could be “promising route” for allergic desensitization. A few years later, the World Health Organization recommended this therapy as “a viable alternative to the injection route in adults.” The first meta-analysis showed sublingual allergen specific immunotherapy (SLIT effectiveness for allergic rhinitis and another study showed SLIT can actually help prevent the development of asthma both in adults and in children. The main goal of this review article is to present insight into the most up-to-date understanding of the clinical efficacy and safety of immunotherapy in the treatment of pediatric patients with allergic rhinitis and asthma. A literature review was performed on PubMed from 1990 to 2015 using the terms “asthma,” “allergic rhinitis,” “children,” “allergen specific immune therapy.” Evaluating data from double-blind placebo-controlled randomized clinical trials (DB-PC-RCTs, the clinical efficacy (assessed as the reduction of symptom score and the need of rescue medicament of SLIT for allergic rhinitis and allergic asthma, has been confirmed in various meta-analysis Outcomes such as rhinoconjunctivitis score and medication scores, combined scores, quality of life, days with severe symptoms, immunological endpoints, and safety parameters were all improved in the SLIT-tablet compared with placebo group. SLIT safety has been already proven in many DB-PC-RCTs and real-life settings. In accordance with all of the above mentioned, the goals for future trials and studies are the development of comprehensive guidelines for clinical practice on immunotherapy, embracing all the different potential participants. The importance of allergen immunotherapy is of special relevance in the pediatric age, when the plasticity and modulability of the immune system are maximal, and when

    Repeated airway exposure to wood dust has been reported to cause adverse respiratory effects such as asthma and chronic bronchitis. In our recent study, we found that exposure of mice to oak dust induced more vigorous lung inflammation compared to birch dust exposure. In the present study, we assessed the immunomodulatory effects of repeated intranasal exposure to oak dust both in nonallergic and in ovalbumin-sensitized, allergic mice. Allergen-induced influx of eosinophils and lymphocytes was seen in the lungs of allergic mice. Oak dust exposure elicited infiltration of neutrophils, lymphocytes, and macrophages in nonallergic mice. Interestingly, oak dust-induced lung neutrophilia as well as oak dust-induced production of the proinflammatory cytokine TNF-alpha and chemokine CCL3 were significantly suppressed in allergic mice. On the other hand, allergen-induced expression of IL-13 mRNA and protein was significantly reduced in oak dust-exposed allergic mice. Finally, allergen-induced airway hyperreactivity to inhaled metacholine was significantly suppressed in oak dust-exposed allergic mice. The present results suggest that repeated airway exposure to oak dust can regulate pulmonary inflammation and airway responses depending on the immunological status of the animal.

  9. Systemic Toll-like receptor stimulation suppresses experimental allergic asthma and autoimmune diabetes in NOD mice.

    Directory of Open Access Journals (Sweden)

    Aude Aumeunier

    Full Text Available BACKGROUND: Infections may be associated with exacerbation of allergic and autoimmune diseases. Paradoxically, epidemiological and experimental data have shown that some microorganisms can also prevent these pathologies. This observation is at the origin of the hygiene hypothesis according to which the decline of infections in western countries is at the origin of the increased incidence of both Th1-mediated autoimmune diseases and Th2-mediated allergic diseases over the last decades. We have tested whether Toll-like receptor (TLR stimulation can recapitulate the protective effect of infectious agents on allergy and autoimmunity. METHODS AND FINDINGS: Here, we performed a systematic study of the disease-modifying effects of a set of natural or synthetic TLR agonists using two experimental models, ovalbumin (OVA-induced asthma and spontaneous autoimmune diabetes, presenting the same genetic background of the non obese diabetic mouse (NOD that is highly susceptible to both pathologies. In the same models, we also investigated the effect of probiotics. Additionally, we examined the effect of the genetic invalidation of MyD88 on the development of allergic asthma and spontaneous diabetes. We demonstrate that multiple TLR agonists prevent from both allergy and autoimmunity when administered parenterally. Probiotics which stimulate TLRs also protect from these two diseases. The physiological relevance of these findings is further suggested by the major acceleration of OVA-induced asthma in MyD88 invalidated mice. Our results strongly indicate that the TLR-mediated effects involve immunoregulatory cytokines such as interleukin (IL-10 and transforming growth factor (TGF-beta and different subsets of regulatory T cells, notably CD4+CD25+FoxP3+ T cells for TLR4 agonists and NKT cells for TLR3 agonists. CONCLUSIONS/SIGNIFICANCE: These observations demonstrate that systemic administration of TLR ligands can suppress both allergic and autoimmune responses

    2016-07-01

    Allergic asthma is a chronic inflammatory disease of the lower airways that affects millions of people worldwide. Allergic asthma is a T helper 2 cell (Th2)-mediated disease, in which Th2 cytokines interleukin (IL)-4, IL-5, and IL-13 are closely associated with the symptoms. IL-4 is needed by B cells to switch toward an IgE response, IL-5 recruits and activates eosinophils while IL-13 increases mucus production. The identification of type 2 innate lymphoid cells (ILC2), which are able to rapidly produce large amounts of IL-5 and IL-13 in response to epithelial derived cytokines, implicated a new key player besides Th2 cells. ILCs constitute a family of innate lymphocytes distinct from T and B cells. ILC2s are located in various epithelial compartments in mice and human, including the lung. The recent finding of increased numbers of ILC2s in the airways of severe asthma patients prompts further research to clarify their immunological function. Murine studies have shown that ILC2s are an early innate source of IL-5 and IL-13 after allergen exposure, which induce airway eosinophilic infiltration, mucus hyperproduction, and airway hyperresponsiveness but not allergen-specific IgE production. ILC2s contribute to the initiation as well as to the maintenance of the adaptive type 2 immune response. Here, we review the recent progress on our understanding of the role of ILC2s in the immunopathology of allergic asthma, in particular by studies using murine models which have elucidated fundamental mechanisms by which ILC2s act.

    Full Text Available A pathophysiologic relationship between allergic rhinitis and rhinosinusitis and asthma has long been suggested. However, few clinical studies of acupuncture have been conducted on these comorbid conditions. A 48-year-old male suffering from persistent allergic rhinitis with comorbid chronic rhinosinusitis and asthma since the age of 18 years was studied. He complained of nasal obstruction, sneezing, cough, rhinorrhea and moderate dyspnea. He occasionally visited local ear-nose-throat clinics for his nasal symptoms, but gained only periodic symptom relief. The patient was treated with acupuncture, infrared radiation to the face and electro-acupuncture. Needles were inserted at bilateral LI20, GV23, LI4 and EX-1 sites with De-qi. Electro-acupuncture was performed simultaneously at both LI20 sites and additional traditional Korean acupuncture treatments were performed. Each session lasted for 10 min and the sessions were carried out twice a week for 5 weeks. The patient’s Mini-Rhinoconjunctivitis Quality-of-Life Questionnaire score decreased from 38, at the beginning of treatment, to 23, 3 weeks after the last treatment. The Total Nasal Symptom Score was reduced from six (baseline to five, 3 weeks after the last treatment. There was significant clinical improvement in the forced expiratory volume in 1 s—from 3.01 to 3.50 l—with discontinuation of the inhaled corticosteroid, and no asthma-related complaints were reported. Further clinical studies investigating the effectiveness of acupuncture for the patients suffering from allergic rhinitis and/or rhinosinusitis with comorbid asthma are needed.

    Full Text Available Background: Allergic bronchopulmonary mycosis (ABPM is a clinical syndrome associated with immune sensitivity to various fungi notably Aspergillus spp. that colonize the airways of asthmatics. Early diagnosis and treatment with systemic corticosteroids is the key in preventing the progression of the disease to irreversible lung fibrosis. Aims: To study the occurrence of ABPM among asthma patients with fungal sensitization attending a chest clinic of a tertiary hospital of eastern India. The clinico-radiological and aetiological profiles are also described. Materials and Methods: All consecutive patients with asthma presenting to the chest clinic over a period of one year were screened for cutaneous hypersensitivity to 12 common fungal antigens. The skin test positive cases were further evaluated for ABPM using standard criteria. Results: One hundred and twenty-six asthma patients were screened using twelve common fungal antigens; forty patients (31.74% were found to be skin test positive, and ABPM was diagnosed in ten patients (7.93%. Of the 10 cases of ABPM, nine cases were those of allergic bronchopulmonary aspergillosis (ABPA and one case was identified as caused by sensitization to Penicillium spp. A majority of the cases of ABPM had advanced disease and had significantly lower FEV1 compared to non-ABPM skin test positive asthmatics. Central bronchiectasis on high resolution CT scan was the most sensitive and specific among the diagnostic parameters. Conclusion: There is a significant prevalence of ABPM in asthma patients attending our hospital and this reinforces the need to screen asthma patients for fungal sensitisation. This will help in early diagnosis and prevention of irreversible lung damage.

    2005-01-01

    Summary: The levels of serum TNF-α and IL-8 in the patients with allergic asthma during acute attack period and remission period, and the effects of glucocorticoid (GC) on them were investigated. By using ELISA, the levels of TNF-α and IL-8 were detected in the healthy volunteers (group C, n=40), the patients with allergic asthma (n=40) during acute attack period (group A) and remission period (group B) and those taking GC for a week (n=28). The results were compared among them. It was found that the levels of TNF-α and IL-8 in group A were higher than in group B and group C. In the patients subject to GC therapy, the levels of TNF-α and IL-8 were decreased as compared with those in group A. In group B, the level of TNF-α was higher than in group C, but there was no significant difference in the level of IL-8 between group B and group C. It was concluded that the inflammatory cytokines, TNF-α and IL-8, played important roles in the bronchus allergic inflammation. GC could reduce the levels of serum TNF-α and IL-8 to exert the anti-inflammatory effects.

    Allergic asthma is a chronic inflammatory airway disease with increasing prevalence around the world. Current asthma therapy includes drugs that usually cause significant side effects, justifying the search for new anti-asthmatic drugs. Curine is a bisbenzylisoquinoline alkaloid that modulates calcium influx in many cell types; however, its anti-allergic and putative toxic effects remain to be elucidated. Our aim was to investigate the effects of curine on eosinophil activation and airway hyper-responsiveness (AHR) and to characterize its potential toxic effects. We used a mouse model of allergic asthma induced by sensitization and challenge with ovalbumin (OVA) to evaluate the anti-allergic effects of oral treatment with curine. The oral administration of curine significantly inhibited eosinophilic inflammation, eosinophil lipid body formation and AHR in animals challenged with OVA compared with animals in the untreated group. The curine treatment also reduced eotaxin and IL-13 production triggered by OVA. Verapamil, a calcium channel antagonist, had similar anti-allergic properties, and curine pre-treatment inhibited the calcium-induced tracheal contractile response ex-vivo, suggesting that the mechanism by which curine exerts its effects is through the inhibition of a calcium-dependent response. A toxicological evaluation showed that orally administered curine did not significantly alter the biochemical, hematological, behavioral and physical parameters measured in the experimental animals compared with saline-treated animals. In conclusion, curine showed anti-allergic activity through mechanisms that involve inhibition of IL-13 and eotaxin and of Ca{sup ++} influx, without inducing evident toxicity and as such, has the potential for the development of anti-asthmatic drugs. - Highlights: • Curine is a bisbenzylisoquinoline alkaloid from Chondrodendron platyphyllum. • Curine inhibits eosinophil influx and activation and airway hyper-responsiveness. • Curine

    Allergic asthma, caused by inhaled allergens such as house dust mite or grass pollen, is characterized by reversible airway obstruction, associated with an eosinophilic inflammation of the airways, as well as airway hyper responsiveness and remodeling. The inhaled allergens trigger a type-2 inflammatory response with involvement of innate lymphoid cells (ILC2) and Th2 cells, resulting in high production of immunoglobulin E (IgE) antibodies. Consequently, renewed allergen exposure results in a classic allergic response with a distinct early and late phase, both resulting in bronchoconstriction and shortness of breath. Allergen specific immunotherapy (AIT) is the only treatment that is capable of modifying the immunological process underlying allergic responses including allergic asthma and both subcutaneous AIT (SCIT) as well as sublingual AIT (SLIT) have proven clinical efficacy in long term suppression of the allergic response. Although these treatments are very successful for rhinitis, application of AIT in asthma is hampered by variable efficacy, long duration of treatment, and the risk of severe side-effects. A more profound understanding of the mechanisms by which AIT achieves tolerance to allergens in sensitized individuals is needed to improve its efficacy. Mouse models have been very valuable as a preclinical model to characterize the mechanisms of desensitization in AIT and to evaluate novel approaches for improved efficacy. Here, we present a rapid and reproducible mouse model for allergen-specific immunotherapy. In this model, mice are sensitized with two injections of allergen absorbed to aluminum hydroxide to induce allergic sensitization, followed by subcutaneous injections (SCIT) or sublingual administrations (SLIT) of the allergen as immunotherapy treatment. Finally, mice are challenged by three intranasal allergen administrations. We will describe the protocols as well as the most important read-out parameters including measurement of invasive lung

    BACKGROUND: Patients with asthma who have persistent symptoms despite treatment with inhaled steroids and long-acting beta agonists are considered to have severe asthma. Omalizumab is a monoclonal antibody directed against IgE, which is used as an add-on treatment for patients who have severe persistent allergic asthma. AIMS: The aim of this study was to assess the clinical benefit and healthcare utilisation of patients who responded to omalizumab therapy and to establish an overall cost implication. METHODS: This was an observational retrospective cohort study designed to investigate the effect of omalizumab on exacerbations of asthma before and after 6 months of treatment in Irish patients. RESULTS: Centres who had treated patients with severe allergic asthma for the 6 months prior and post omalizumab treatment were audited with a standardised assessment tool. Sixty-three (32 male) patients were studied. In the 6 months prior to omalizumab 41 of 63 (66%) had been hospitalised, and this fell to 15 of 63 (24%), p < 0.0001 in the 6 months after treatment was started. Hospital admissions reduced from 2.4 ± 0.41 to 0.8 ± 0.37 and the mean number of bed days occupied was reduced from 16.6 ± 2.94 to 5.3 ± 2.57 days, p < 0.001. The number of oral corticosteroid doses used fell from 3.1 ± 0.27 to 1.2 ± 0.17, p < 0.001. The overall cost saving per omalizumab responder patients for 6 months was 834. CONCLUSIONS: Six months therapy with omalizumab reduced the number of bed days, the number of hospitalisations and the use of oral corticosteroids compared to the 6 months prior to commencement. Despite the cost of the additional therapy there were overall savings in health costs.

    Full Text Available Background: Most of the hypogammaglobulinemic patients have a clinical history in favor of allergic respiratory disease. Nevertheless, in these patients the importance and prevalence of atopic disorders have not been completely explained. Objectives: This study was aimed to evaluate atopic manifestations (dermatitis, allergic rhinitis and asthma and pulmonary function in patients with hypogammaglobulinemia. Patients and Methods: We used the international study of asthma and allergies in childhood (ISAAC questionnaire in forty-five patients diagnosed with hypogammaglobulinemia and spirometry was done in 41 patients older than 5 years. Results: Spirometry results were normal in 21 (51%, and showed obstructive in 15 (37% and restrictive pattern in 5 (12% of the 41 patients who were evaluated. By the end of the study, asthma was diagnosed in nine (20% patients and other atopies (rhinitis and dermatitis identified in 10 (22%, and four (9%, respectively. Conclusions: Atopic conditions should be investigated in the hypogammaglobulinemic patients and the prevalence in these patients may be higher than in normal population. Also, it is recommended to perform a pulmonary function test as a routine procedure in patients with hypogammaglobulinemia and atopy should be assessed in these patients.

  19. Role of omega-3 fatty acids and their metabolites in asthma and allergic diseases.

    Omega-3 fatty acids, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are found naturally in fish oil and are commonly thought to be anti-inflammatory nutrients, with protective effects in inflammatory diseases including asthma and allergies. The mechanisms of these effects remain mostly unknown but are of great interest for their potential therapeutic applications. Large numbers of epidemiological and observational studies investigating the effect of fish intake or omega-3 fatty acid supplementation during pregnancy, lactation, infancy, childhood, and adulthood on asthmatic and allergic outcomes have been conducted. They mostly indicate protective effects and suggest a causal relationship between decreased intake of fish oil in modernized diets and an increasing number of individuals with asthma or other allergic diseases. Specialized pro-resolving mediators (SPM: protectins, resolvins, and maresins) are generated from omega-3 fatty acids such as EPA and DHA via several enzymatic reactions. These mediators counter-regulate airway eosinophilic inflammation and promote the resolution of inflammation in vivo. Several reports have indicated that the biosynthesis of SPM is impaired, especially in severe asthma, which suggests that chronic inflammation in the lung might result from a resolution defect. This article focuses on the beneficial aspects of omega-3 fatty acids and offers recent insights into their bioactive metabolites including resolvins and protectins.

    With the levels of outdoor air pollution from industrial and motor vehicle emissions rising rapidly in the fastly-industrializing countries of South East Asia, the prevalence of asthma and allergic diseases has also been increasing to match those in the West. Epidemiological and experimental exposure studies indicate a harmful impact of outdoor air pollution from vehicles and factories both on the development of allergic diseases and asthma and the increase in asthma symptoms and exacerbations. The level of outdoor pollution in Asia is much higher and more diverse than those encountered in Western countries. This may increase the impact of outdoor pollution on health, particularly lung health in Asia. This review discusses the constituents of air pollution in Asia with a special focus on studies in mainland China and Taiwan where the levels of pollution have reached high levels and where such high levels particularly in winter can cause a thick haze that reduces visibility. The onus remains on regulatory and public health authorities to curb the sources of pollution so that the health effects on the population particularly those with lung and cardiovascular diseases and with increased susceptibility can be mitigated.

    The asthmatic inflammatory responses present different type of cells involved in this process, such as: Lymphocytes and Eosinophils. In experienced hands the bronchoalveolar lavage (BAL) is a well-tolerated and valuable tool for investigation of basic mechanisms in asthma and other immunological respiratory diseases. The purpose of this work was to study the different cells involved in asthmatic inflammatory responses in allergic and aspirin sensitivity patients and compared with Extrinsic Allergic Alveolitis patients (EAA) by BAL procedure. We studied 27 asthmatic patients. This group was divided by etiological conditions in: allergic asthmatic patients (a) (n: 19), (9 male and 10 female) demonstrated by reversible fall of FEV 1 (3) 20% and 2 or more positive skin test for common aeroallergens. The aspirin asthmatic patients (b) (n: 8) (5 male and 3 female) demonstrated by progressive challenge with aspirin and fall of FEV 1 (3) 20%. The third group with compatible symptoms and signs of EAA, demonstrated by lung biopsy, (n: 9) (8 male and 1 female) (c). We determined in all patients: Total IgE serum level by ELISA test. BAL was performed by standard procedure in all patients. The cells count were performed in BAL and were separated in Eosinophils, T lymphocytes defined by monoclonal anti CD 3 antibody, Lymphocytes CD 4 and CD 8 by monoclonal anti CD 4 and CD 8 antibodies respectively. The B lymphocytes defined by surface immunoglobulin isotypes IgG, IgM, IgA and IgE. The IgE level was in (a) 630 +/- 350 kU/L, in (b) it was 85 +/- 62 kU/L and in EAA (c) 55 +/- 23 kU/L, p allergic asthmatic patients as well as in aspirin sensitivity asthmatic patients. The LBA cellular profile of E.AA patients presented eosinophilia and CE8+ Lymphocite predominance when compared with both asthmatic cellular profile.

    This study investigated the pollution of dust mite allergens in the houses of 30 families and their infection to young allergic asthma patients in Shanghai. Medical records, family information, and dust samples were collected from the dwellings of 15 young allergic asthma patients and 15 healthy subjects. Der 1 allergen, which is a common allergen causing allergic asthma, was measured in collected dust samples using the Pharmacia Uni-CAP System. A significant correlation was found between the number of Der 1 allergens collected from floor surfaces and the number of Der 1 allergens collected from bed surfaces. Some factors influencing Der 1 allergen levels were found in this study. Relative humidity in dwellings was found to be most influential to the allergen levels. The findings suggested that traditional reduction methods for coarse particles, such as opening windows and periodic cleaning of beddings, may be effective in removing dust mite allergens.

    Allergic asthma represents an important public health issue, most common in the paediatric population, characterized by airway inflammation that may lead to changes in volatiles secreted via the lungs. Thus, exhaled breath has potential to be a matrix with relevant metabolomic information to characterize this disease. Progress in biochemistry, health sciences and related areas depends on instrumental advances, and a high throughput and sensitive equipment such as comprehensive two-dimensional gas chromatography-time of flight mass spectrometry (GC×GC-ToFMS) was considered. GC×GC-ToFMS application in the analysis of the exhaled breath of 32 children with allergic asthma, from which 10 had also allergic rhinitis, and 27 control children allowed the identification of several hundreds of compounds belonging to different chemical families. Multivariate analysis, using Partial Least Squares-Discriminant Analysis in tandem with Monte Carlo Cross Validation was performed to assess the predictive power and to help the interpretation of recovered compounds possibly linked to oxidative stress, inflammation processes or other cellular processes that may characterize asthma. The results suggest that the model is robust, considering the high classification rate, sensitivity, and specificity. A pattern of six compounds belonging to the alkanes characterized the asthmatic population: nonane, 2,2,4,6,6-pentamethylheptane, decane, 3,6-dimethyldecane, dodecane, and tetradecane. To explore future clinical applications, and considering the future role of molecular-based methodologies, a compound set was established to rapid access of information from exhaled breath, reducing the time of data processing, and thus, becoming more expedite method for the clinical purposes.

    Allergic bronchopulmonary aspergillosis (ABPA) complicates asthma and may lead to chronic pulmonary aspergillosis (CPA) yet global burdens of each have never been estimated. Antifungal therapy has a place in the management of ABPA and is the cornerstone of treatment in CPA, reducing morbidity and probably mortality. We used the country-specific prevalence of asthma from the Global Initiative for Asthma (GINA) report applied to population estimates to calculate adult asthma cases. From five referral cohorts (China, Ireland, New Zealand, Saudi Arabia and South Africa), we estimated the prevalence of ABPA in adults with asthma at 2.5% (range 0.72-3.5%) (scoping review). From ABPA case series, pulmonary cavitation occurred in 10% (range 7-20%), allowing an estimate of CPA prevalence worldwide using a deterministic scenario-based model. Of 193 million adults with active asthma worldwide, we estimate that 4,837,000 patients (range 1,354,000-6,772,000) develop ABPA. By WHO region, the ABPA burden estimates are: Europe, 1,062,000; Americas, 1,461,000; Eastern Mediterranean, 351,000; Africa, 389,900; Western Pacific, 823,200; South East Asia, 720,400. We calculate a global case burden of CPA complicating ABPA of 411,100 (range 206,300-589,400) at a 10% rate with a 15% annual attrition. The global burden of ABPA potentially exceeds 4.8 million people and of CPA complicating ABPA ˜ 400,000, which is more common than previously appreciated. Both conditions respond to antifungal therapy justifying improved case detection. Prospective population and clinical cohort studies are warranted to more precisely ascertain the frequency of ABPA and CPA in different locations and ethnic groups and validate the model inputs.

    Full Text Available The records of patients from the Allergology Service in the Previsora Policlinic, Camagüey were revised to evaluate benefits and risks of the subcutaneous immunotherapy (ITSC with extracts of acari. The study was observational, analytic and retrospective of cases and controls in allergic rhinoconjunctivitis and bronchial asthma. A total of 160 subjects, older than 18 years old, were chosen. Eighty out of them had already received ITSC with dose increase during 13 weeks and maintenance with monthly injections during 18 months. A total of 80 patients who only received prevention measures and medications during the crises were paired. Questionnaires were applied for quality of rhinoconjunctivitis life and asthma, about the consumption of medications and the frequency of the crises. The adverse events were measured, as they were local and systemic to the cutaneous tests, to the ITSC and the different pharmacological treatments. There was a significant increase of the punctuation of life quality questionnaires, (p=0.011. The consumption of medications decreased in both the cases and the controls, without significant differences (p=0.083. The frequency of the rhinitis and asthma crises decrease in the group of ITSC (p=0.029. Slight local and systemic reactions were reported in both groups with Odds ratio (OR=2.029 in the ITSC group, with a 95% confidence interval of 1.114–3.967 (p=0.019. The results show that the subcutaneous immunotherapy with acari offers benefits and few risks to patients with allergic rhinoconjunctivitis and asthma.

    2005-03-01

    The use of Complementary/Alternative Medicines (CAM) is largely diffused and constantly increasing, especially in the field of allergic diseases and asthma. Homeopathy, acupuncture and phytotherapy are the most frequently utilised treatments, whereas complementary diagnostic techniques are mainly used in the field of food allergy-intolerance. Looking at the literature, the majority of clinical trials with CAMS are of low methodological quality, thus difficult to interpret. There are very few studies performed in a rigorously controlled fashion, and those studies provided inconclusive results. In asthma, none of the CAM have thus far been proved more effective than placebo or equally effective as standard treatments. Some herbal products, containing active principles, have displayed some clinical effect, but the herbal remedies are usually not standardised and not quantified, thus carry the risk of toxic effects or interactions. None of the alternative diagnostic techniques (electrodermal testing, kinesiology, leukocytotoxic test, iridology, hair analysis) have been proved able to distinguish between healthy and allergic subjects or to diagnose sensitizations. Therefore these tests must not be used, since they can lead to delayed or incorrect diagnosis and therapy.

  12. Treatment of allergic asthma: Modulation of Th2 cells and their responses

    Directory of Open Access Journals (Sweden)

    Erb Klaus J

    2011-08-01

    Full Text Available Abstract Atopic asthma is a chronic inflammatory pulmonary disease characterised by recurrent episodes of wheezy, laboured breathing with an underlying Th2 cell-mediated inflammatory response in the airways. It is currently treated and, more or less, controlled depending on severity, with bronchodilators e.g. long-acting beta agonists and long-acting muscarinic antagonists or anti-inflammatory drugs such as corticosteroids (inhaled or oral, leukotriene modifiers, theophyline and anti-IgE therapy. Unfortunately, none of these treatments are curative and some asthmatic patients do not respond to intense anti-inflammatory therapies. Additionally, the use of long-term oral steroids has many undesired side effects. For this reason, novel and more effective drugs are needed. In this review, we focus on the CD4+ Th2 cells and their products as targets for the development of new drugs to add to the current armamentarium as adjuncts or as potential stand-alone treatments for allergic asthma. We argue that in early disease, the reduction or elimination of allergen-specific Th2 cells will reduce the consequences of repeated allergic inflammatory responses such as lung remodelling without causing generalised immunosuppression.

    Full Text Available BACKGROUND: Past evidence has suggested a role of artificial sweeteners in allergic disease; yet, the evidence has been inconsistent and unclear. OBJECTIVE: To examine relation of intake of artificially-sweetened beverages during pregnancy with child asthma and allergic rhinitis at 18 months and 7 years. METHODS: We analyzed data from 60,466 women enrolled during pregnancy in the prospective longitudinal Danish National Birth Cohort between 1996 and 2003. At the 25th week of gestation we administered a validated Food Frequency Questionnaire which asked in detail about intake of artificially-sweetened soft drinks. At 18 months, we evaluated child asthma using interview data. We also assessed asthma and allergic rhinitis through a questionnaire at age 7 and by using national registries. Current asthma was defined as self-reported asthma diagnosis and wheeze in the past 12 months. We examined the relation between intake of artificially-sweetened soft drinks and child allergic disease outcomes and present here odds ratios with 95% CI comparing daily vs. no intake. RESULTS: At 18 months, we found that mothers who consumed more artificially-sweetened non-carbonated soft drinks were 1.23 (95% CI: 1.13, 1.33 times more likely to report a child asthma diagnosis compared to non-consumers. Similar results were found for child wheeze. Consumers of artificially-sweetened carbonated drinks were more likely to have a child asthma diagnosis in the patient (1.30, 95% CI: 1.01, 1.66 and medication (1.13, 95% CI: 0.98, 1.29 registry, as well as self-reported allergic rhinitis (1.31, 95% CI: 0.98, 1.74 during the first 7 years of follow-up. We found no associations for sugar-sweetened soft drinks. CONCLUSION: Carbonated artificially-sweetened soft drinks were associated with registry-based asthma and self-reported allergic rhinitis, while early childhood outcomes were related to non-carbonated soft drinks. These results suggest that consumption of artificially

    Curcumin, a natural product derived from the plant Curcuma longa, has been found to have anti-inflammatory, antineoplastic and antifibrosis effects. It has been reported that curcumin attenuates allergic airway inflammation in mice through inhibiting NF-κB and its downstream transcription factor GATA3. It also has been proved the antineoplastic effect of curcumin through down-regulating Notch1 receptor and its downstream nuclear transcription factor NF-κB levels. In this study, we aimed to investigate the anti-inflammatory effect of curcumin on acute allergic asthma and its underlying mechanisms. 36 male BALB/c mice were randomly divided into four groups (normal, asthma, asthma+budesonide and asthma+curcumin groups). BALF (bronchoalveolar lavage fluid) and lung tissues were analyzed for airway inflammation and the expression of Notch1, Notch2, Notch3, Notch4 and the downstream transcription factor GATA3. Our findings showed that the levels of Notch1 and Notch2 receptors were up-regulated in asthma group, accompanied by the increased expression of GATA3. But the expression of Notch2 receptor was lower than Notch1 receptor. Curcumin pretreatment improved the airway inflammatory cells infiltration and reversed the increasing levels of Notch1/2 receptors and GATA3. Notch3 receptor was not expressed in all of the four groups. Notch4 receptor protein and mRNA expression level in the four groups had no significant differences. The results of the present study suggested that Notch1 and Notch2 receptor, major Notch1 receptor, played an important role in the development of allergic airway inflammation and the inhibition of Notch1-GATA3 signaling pathway by curcumin can prevent the development and deterioration of the allergic airway inflammation. This may be a possible therapeutic option of allergic asthma.

    Full Text Available Phosphodiesterases  (PDE  hydrolyse intracellular cAMP  and  cGMP  to  inactive  5’ monophosphates. Decreased level of cAMP is involved in the pathogenesis of asthma. We and others have shown that phosphodiesterases were upregulated in the lung of allergic rats, and Bacilli Calmette-Guérin (BCG induced the production of cAMP in vitro. However, it is unclear how BCG’s effect asthma and whether it is related to PDEs.In  this  study,  BCG  was  intraperitoneally  injected  into  male  Sprague-Dawley rats sensitized and later the rats were challenged with ovabumin/pertusis. The inflammation in lungs was measured. Airway hyperresponsiveness was determined using MedLab software after intravenous methacholine challenge. Furthermore,  cAMP level and adenylate cyclase activity in lungs were analyzed by ELISA, phosphodiesterases activities were analyzed by HPLC, while PDEs mRNA levels in lungs was analyzed by reverse transcription-polymerase chain  reaction.  Administration  of  BCG  significantly attenuated  allergen-induced  lung inflammatory response  and  hyper  responsiveness  as  compared  with  vehicle treatment. Furthermore,  the  levels of  cAMP in lungs were significantly increased in  BCG-treated allergic rats. Interestingly, administration of BCG decreased the activity of cAMP-PDE, but not adenylyl cyclase (AC, activity in lungs of animals. Furthermore, pretreatment with BCG significantly decreased the mRNA levels of PDE4A, 4C, 5 and 8, which were induced in lungs of allergic rats.BCG  administration  attenuated  airway inflammatory  response  and  bronchial  hyper responsiveness in rats, which are the most important symptoms in asthma. The decreased PDEs  mRNA  and  inhibited cAMP-PDE  activities by BCG  contribute,  at least in part, prevention of allergen-induced airway inflammation and asthma in rats.

    Allergic asthma is driven by relative overexpression of Th2 cell-derived cytokines in response to aeroallergens. In independent studies, both allergen-specific rush immunotherapy (RIT) and CpG oligodeoxynucleotides (ODN) showed promise in blunting eosinophilic inflammation in a model of feline allergic asthma. We hypothesized that RIT using allergen and CpG ODN would work synergistically to dampen the asthmatic phenotype in experimentally asthmatic cats. Twelve cats with asthma induced using Bermuda grass allergen (BGA) were studied. Of these, six were administered adjuvanted BGA RIT using CpG ODN #2142; six were administered placebo (saline) RIT and later crossed over to adjuvanted RIT. Over 2 days, subcutaneous CpG ODN (0.5ng/kg) with BGA (increasing doses every 2h from 20 to 200microg) was administered. Adverse events were recorded and compared with historical controls. Percentage of eosinophils in bronchoalveolar lavage fluid (BALF), % peripheral CD4+CD25+ T regulatory cells (Tregs), lymphocyte proliferation in response to ConA, and cytokine concentrations in BALF were measured over 2 months. Group mean BALF % eosinophils for the adjuvanted RIT cats were significantly lower at week 1 and month 1 (p=0.03 for both), and marginally significantly lower at month 2 (p=0.09) compared with placebo RIT cats. By the end of the study, 8/12 treated cats had BALF % eosinophils within the reference range for healthy cats. Adjuvanted RIT, but not placebo RIT, cats had significant decreases in the ConA stimulation index over time (p=0.05). BALF IL-4 concentrations were significantly higher at week 1 in adjuvanted RIT cats compared with baseline and month 2, and also with placebo RIT cats at week 1. No significant differences were detected between treatments or over time for IL-10 or IFN-gamma concentrations in BALF or for %Tregs cells in peripheral blood. Adjuvanted RIT using CpG ODN in experimental feline asthma dampens eosinophilic airway inflammation. Adverse effects

    Background Eosinophils are highly related to allergic asthma inflammation. Interleukin (IL)-5 is the major chemokine of eosinophils, inhibition of the activity of IL-5 thus seems to be a potential approach to asthma therapy. The current study was performed to determine whether a recombinant human IL-5 protein as a xenogeneic vaccine has the capability of inducing anti-asthma activities.Methods Recombinant human IL-5 was used as a protein vaccine. Mouse asthma model was established to observe the anti-asthma activities. Lung histology was observed; eosinophils in blood and bronchoalveolar lavage were stained and counted. Airway hyperresponsiveness was determined by whole body plethysmograph. Antibody characters and cytokines were detected with enzyme linked immunosorbent assay (ELISA) and Western blot assay.Results Vaccination with recombinant human IL-5 protein as vaccine significantly reduced airway inflammation and airway hyperresponsiveness, and shifted the cytokine production from Th2 (IL-4) to Th1 (INF-γ) in mice allergic-asthma model. Immunization with recombinant human IL-5 protein vaccine bypassed the immunological tolerance and induced production of polyclonal antibodies that were cross-reactive with murine IL-5.Conclusions Active immunization with xenogeneic homologous IL-5 may be a possible therapeutic approach to the treatment of asthma and potentially of other eosinophilic disorders.

    The aim of the study was to investigate the anti-asthmatic effects of matrine and the possible mechanisms. Asthma model was established by ovalbumin-induced. A total of 50 mice were randomly assigned to five experimental groups: control, model, dexamethasone (2 mg/kg) and matrine (50 mg/kg, 100 mg/kg). Airway resistance (Raw) was measured, histological studies were evaluated by the hematoxylin and eosin (HE) staining, interleukin-4 (IL-4) and interleukin-13 were evaluated by enzyme-linked immunosorbent assay (ELISA), IL-4 and IL-13 signal protein STAT6 was measured by western blotting. Our study demonstrated that matrine inhibited OVA-induced increases in Raw and eosinophil count; IL-4 and IL-13 were recovered. Histological studies demonstrated that matrine substantially inhibited OVA-induced eosinophilia in lung tissue. Western blotting studies demonstrated that matrine substantially inhibited STAT6 protein level. These findings suggest that matrine may effectively ameliorate the progression of asthma and could be used as a therapy for patients with allergic asthma.

    Full Text Available The efficacy of omalizumab has been extensively investigated in clinical trials in patients with severe persistent allergic (pre-treatment total immunoglobulin E 30–700 IU·mL–1 asthma including the Investigation of Omalizumab in Severe Asthma Treatment (INNOVATE study, which enrolled patients with inadequately controlled severe persistent allergic asthma despite receiving high-dose inhaled corticosteroid in combination with a long-acting beta2-agonist, and also additional controller medication if required. In the INNOVATE study, add-on omalizumab significantly reduced clinically significant exacerbation rates by 26% (0.68 versus 0.91, severe exacerbation rates by 50% (0.24 versus 0.48 and emergency visit rates by 44% (0.24 versus 0.43 and significantly improved asthma-related quality of life (QoL compared with placebo. In a pooled analysis of data from seven studies, add-on omalizumab significantly reduced asthma exacerbation rates by 38% (0.91 versus 1.47 and total emergency visits by 47% (0.332 versus 0.623. In addition, omalizumab significantly improved QoL versus current asthma therapy in a pooled analysis of data from six studies. Omalizumab has demonstrated a good safety and tolerability profile in completed phase-I, -II and -III studies involving >7,500 patients with asthma, rhinitis or related conditions. Omalizumab represents a major advance for the treatment of severe persistent allergic asthma that is inadequately controlled despite treatment with inhaled corticosteroids and a long-acting beta2-agonist.

    We investigated the plasma concentration of the novel regulatory cytokine IL-35 and intracytosolic pattern recognition receptors nucleotide-binding oligomerization domain (NOD)-like receptors in granulocytes and explored their potential implication in disease severity monitoring of allergic asthma. The expression of circulating IL-35 and other pro-inflammatory mediators in asthmatic patients or control subjects were evaluated using enzyme-linked immunosorbent assay (ELISA). The intracellular expressions of NOD1 and NOD2 in CCR3+ granulocytes were assessed using flow cytometry. Plasma concentrations of IL-35, IL-17A, basophil activation marker basogranulin, and eosinophilic airway inflammation biomarker periostin were significantly elevated in allergic asthmatic patients compared to non-atopic control subjects (all probability (p) IL-35 concentration in asthmatic patients (all p IL-35 and periostin with disease severity score in asthmatic patients (both p IL-35 (p IL-35 may serve as a potential surrogate biomarker for disease severity of allergic asthma.

    Plasminogen activator inhibitor (PAI-1) has an essential role in tissue remodeling after inflammation. Recent literature revealed only one study evaluating PAI-1 4G/5G gene polymorphism in children with asthma and none in children with allergic rhinitis. We aimed to investigate distribution of PAI-1 4G/5G polymorphism in a group of Turkish children with asthma and allergic rhinitis and compare these findings with those obtained in normal peers. Patients with physician-diagnosed asthma (n = 106) and allergic rhinitis (n = 99) and 83 healthy peers were included in this study. We evaluated PAI-1 4G/5G polymorphism genotype as well as the possible association between PAI-1 4G/5G polymorphism and pulmonary function tests, serum total immunoglobulin E (IgE), total eosinophil count, and skin-prick test positivity in our study. The prevalence of the 4G allele significantly exceeded the values found in the controls both in patients with asthma (p = 0.001) and in patients with allergic rhinitis (p = 0.002). Interestingly, comparison of asthmatic patients revealed that mean baseline percent forced expiratory volume in 1 second and forced vital capacity were significantly higher in patients who bear 5G/5G genotype than in those who have 4G/4G or 4G/5G genotypes. No statistically significant relationship were found between PAI-1 polymorphism and total serum IgE levels, total eosinophil count, or selected skin test responses to aeroallergens. Our study suggests that Turkish children with asthma or allergic rhinitis have a higher prevalence of PAI-1 4G allele compared with their healthy peers.

    Both therapies of traditional crude herb moxibustion and drug acupoint application were used in 209 cases of allergic asthma to compare their long-term and short-term therapeutic effects and to analyze the relationship between clinic therapeutic effects of both therapies and differential types of the disease. The results showed that the short-term total effective rate in the group of drug acupoint application was higher than that in the group of traditional crude herb moxibustion, the therapeutic effects of drug acupoint application being closely related to differential types. Analysis also shows the best short-term therapeutic effect was in the type of heat in the lung while the poorest effect in the type of deficiency of the kidney-yang.

    There is considerable evidence that T-helper 2 (Th2) cells play a central role in the pathogenesis of allergic diseases such as bronchial asthma, hay fever or food allergy. The differentiation of naïve T cells into Th2 cells producing a specific pattern of cytokines is tightly controlled and regulated by transcription factors. Thus down-regulation of mRNA-levels of a single transcription factor leads to a "knock-down" of several mediators simultaneously, representing an advantage compared to earlier approaches involving down-regulation of one intercellular inflammatory mediator, which is unlikely to influence all pathophysiological aspects of the disease. We review the impact of specific and master transcription factors involved in Th2 cell commitment and evaluate approaches for the down-regulation of these proteins by degradation of their mRNA using nucleic-acid based technologies including antisense oligonucleotides, ribozymes, DNAzymes, decoys oligonucleotides and RNA interference.

    During the last decade, there has been a remarkable and unexplained increase in the prevalence of asthma. These studies were conducted to investigate the role of dermal exposure to triclosan, an endocrine-disrupting compound, on the hypersensitivity response to ovalbumin (OVA) in a murine model of asthma. Triclosan has had widespread use in the general population as an antibacterial and antifungal agent and is commonly found in consumer products such as soaps, deodorants, toothpastes, shaving creams, mouthwashes, and cleaning supplies. For these studies, BALB/c mice were exposed dermally to concentrations of triclosan ranging from 0.75 to 3% (0.375-1.5mg/mouse/day) for 28 consecutive days. Concordantly, mice were ip injected with OVA (0.9 µg) and aluminum hydroxide (0.5mg) on days 1 and 10 and challenged with OVA (125 µg) by pharyngeal aspiration on days 19 and 27. Compared with the animals exposed to OVA alone, increased spleen weights, OVA-specific IgE, interleukin-13 cytokine levels, and numbers of lung eosinophils were demonstrated when mice were coexposed to OVA and triclosan. Statistically significant increases in OVA-specific and nonspecific airway hyperreactivity were observed for all triclosan coexposed groups compared with the vehicle and OVA controls. In these studies, exposure to triclosan alone was not demonstrated to be allergenic; however, coexposure with a known allergen resulted in enhancement of the hypersensitivity response to that allergen, suggesting that triclosan exposure may augment the allergic responses to other environmental allergens.

    Full Text Available An acidic microenvironment has been shown to evoke a variety of airway responses, including cough, bronchoconstriction, airway hyperresponsiveness (AHR, infiltration of inflammatory cells in the lung, and stimulation of mucus hyperproduction. Except for the participation of transient receptor potential vanilloid-1 (TRPV1 and acid-sensing ion channels (ASICs in severe acidic pH (of less than 6.0-induced cough and bronchoconstriction through sensory neurons, the molecular mechanisms underlying extracellular acidic pH-induced actions in the airways have not been fully understood. Recent studies have revealed that ovarian cancer G protein-coupled receptor 1 (OGR1-family G protein-coupled receptors, which sense pH of more than 6.0, are expressed in structural cells, such as airway smooth muscle cells and epithelial cells, and in inflammatory and immune cells, such as eosinophils and dendritic cells. They function in a variety of airway responses related to the pathophysiology of inflammatory diseases, including allergic asthma. In the present review, we discuss the roles of ionotropic TRPV1 and ASICs and metabotropic OGR1-family G protein-coupled receptors in the airway inflammation and AHR in asthma and respiratory diseases.

    2011-02-01

    Full Text Available Abstract Background Th2 cell activation and T regulatory cell (Treg deficiency are key features of allergy. This applies for asthma and rhinitis. However with a same atopic background, some patients will develop rhinitis and asthma, whereas others will display rhinitis only. Co-receptors are pivotal in determining the type of T cell activation, but their role in allergic asthma and rhinitis has not been explored. Our objective was to assess whether allergen-induced T cell activation differs from allergic rhinitis to allergic rhinitis with asthma, and explore the role of ICOS, CD28 and CTLA-4. Methods T cell co-receptor and cytokine expressions were assessed by flow cytometry in PBMC from 18 house dust mite (HDM allergic rhinitics (R, 18 HDM allergic rhinitics and asthmatics (AR, 13 non allergic asthmatics (A and 20 controls, with or without anti-co-receptors antibodies. Results In asthmatics (A+AR, a constitutive decrease of CTLA-4+ and of CD4+CD25+Foxp3+ cells was found, with an increase of IFN-γ+ cells. In allergic subjects (R + AR, allergen stimulation induced CD28 together with IL-4 and IL-13, and decreased the proportion of CTLA-4+, IL-10+ and CD4+CD25+Foxp3+ cells. Anti-ICOS and anti-CD28 antibodies blocked allergen-induced IL-4 and IL-13. IL-13 production also involved CTLA-4. Conclusions T cell activation differs between allergic rhinitis and asthma. In asthma, a constitutive, co-receptor independent, Th1 activation and Treg deficiency is found. In allergic rhinitis, an allergen-induced Treg cell deficiency is seen, as well as an ICOS-, CD28- and CTLA-4-dependent Th2 activation. Allergic asthmatics display both characteristics.

    Introduction Asthma is one of the most frequently diagnosed respiratory diseases in the UK, and commonly co-occurs with other respiratory and allergic diseases, such as chronic obstructive pulmonary disease (COPD) and atopic dermatitis. Previous studies have shown an increased risk of lung cancer related to asthma, but the evidence is mixed when accounting for co-occurring respiratory diseases and allergic conditions. A systematic review of published data that investigate the relationship between asthma and lung cancer, accounting for co-occurring respiratory and allergic diseases, will be conducted to investigate the independent association of asthma with lung cancer. Methods and analysis A systematic review will be conducted, and include original reports of cohort, cross-sectional and case–control studies of the association of asthma with lung cancer after accounting for co-occurring respiratory diseases. Articles published up to June 2016 will be included, and their selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A standardised data extraction form will be developed and pretested, and descriptive analyses will be used to summarise the available literature. If appropriate, pooled effect estimates of the association between asthma and lung cancer, given adjustment for a specific co-occurring condition will be estimated using random effects models. Potential sources of heterogeneity and between study heterogeneity will also be investigated. Ethics and dissemination The study will be a review of published data and does not require ethical approval. Results will be disseminated through a peer-reviewed publication.

    Full Text Available Bronchial thermoplasty (BT is a recently developed treatment for patients with moderate-to-severe asthma. A few studies have suggested the clinical efficacy of this intervention. However, no study has evaluated the cost-effectiveness of BT compared to other alternative treatments for moderate-to-severe allergic asthma, which currently include omalizumab and standard therapy.To evaluate the cost-effectiveness of standard therapy, BT, and omalizumab for moderate-to-severe allergic asthma in the USA.A probabilistic Markov model with weekly cycles was developed to reflect the course of asthma progression over a 5-year time horizon. The study population was adults with moderate-to-severe allergic asthma whose asthma remained uncontrolled despite using high-dose inhaled corticosteroids (ICS, with or without long-acting beta-agonists [LABA]. A perspective of the health-care system was adopted with asthma-related costs as well as quality-adjusted life years (QALYs and exacerbations as the outcomes.For standard therapy, BT, and omalizumab, the discounted 5-year costs and QALYs were $15,400 and 3.08, $28,100 and 3.24, and $117,000 and 3.26, respectively. The incremental cost-effectiveness ratio (ICER of BT versus standard therapy and omalizumab versus BT was $78,700/QALY and $3.86 million/QALY, respectively. At the willingness-to-pay (WTP of $50,000/QALY and $100,000/QALY, the probability of BT being cost-effective was 9%, and 67%, respectively. The corresponding expected value of perfect information (EVPI was $155 and $1,530 per individual at these thresholds. In sensitivity analyses, increasing the costs of BT from $14,900 to $30,000 increased its ICER relative to standard therapy to $178,000/QALY, and decreased the ICER of omalizumab relative to BT to $3.06 million/QALY. Reducing the costs of omalizumab by 25% decreased its ICER relative to BT by 29%.Based on the available evidence, our study suggests that there is more than 60% chance that BT becomes

    Perfluoroalkyl substances (PFASs) are highly persistent chemicals that might be associated with asthma and allergy, but the associations remain unclear. Therefore, this study examined whether pre- and postnatal PFAS exposure was associated with childhood asthma and allergy. Measles, mumps, and rubella (MMR) vaccination in early life may have a protective effect against asthma and allergy, and MMR vaccination is therefore taken into account when evaluating these associations. In a cohort of Faroese children whose mothers were recruited during pregnancy, serum concentrations of five PFASs - Perfluorohexane sulfonic acid (PFHxS), perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorodecanoic acid (PFDA) - were measured at three timepoints (maternal serum in pregnancy week 34-36 and child serum at ages 5 and 13 years) and their association with immunoglobulin E (IgE) (cord blood and at age 7 years) and asthma/allergic diseases (questionnaires at ages 5 and 13 years and skin prick test at age 13 years) was determined. A total of 559 children were included in the analyses. Interactions with MMR vaccination were evaluated. Among 22 MMR-unvaccinated children, higher levels of the five PFASs at age 5 years were associated with increased odds of asthma at ages 5 and 13. The associations were reversed among MMR-vaccinated children. Prenatal PFAS exposure was not associated with childhood asthma or allergic diseases regardless of MMR vaccination status. In conclusion, PFAS exposure at age 5 was associated with increased risk of asthma among a small subgroup of MMR-unvaccinated children but not among MMR-vaccinated children. While PFAS exposure may impact immune system functions, this study suggests that MMR vaccination might be a potential effect-modifier.

    Full Text Available Abstract Background The Control of Allergic Rhinitis and Asthma Test (CARAT10 has been proposed as the first tool to implement the Allergic Rhinitis and its Impact on Asthma initiative guidelines in clinical practice. To serve this purpose, it must have adequate properties to assess the control of an individual over time. This study aimed to prospectively assess the test-retest reliability, responsiveness and longitudinal validity of CARAT10. Methods Adults with asthma and allergic rhinitis were enrolled at 4 outpatient clinics of Portuguese central hospitals. At each of the two visits, 4 to 6 weeks apart, patients filled out CARAT10 and additional questionnaires, followed by a medical evaluation blinded to the questionnaires’ answers. Results From the 62 patients included, 51 patients completely filled out CARAT10 at both visits. The test-retest reliability, computed as an intra-class correlation coefficient, was 0.82. Regarding responsiveness, a significant change (p = 0.002 of CARAT10 score in clinically unstable patients was observed (95%CI -5.08; -1.31 and the Guyatt’s responsiveness index was 1.54. As for the longitudinal validity assessment, the correlation coefficients of the changes of CARAT10 scores with those of ACQ5 and symptoms VAS ranged from 0.49 to 0.65, while with the physician assessment of control they ranged from 0.31 to 0.41. Conclusion CARAT10 has good test-retest reliability, responsiveness and longitudinal validity. It can be used to assess control of allergic rhinitis and asthma, both to compare groups in clinical studies and to evaluate individual patients in clinical practice.

    Background Sleep disordered breathing (SDB) and sleep disturbances have been reported to be associated with allergic rhinitis and asthma. However, population-based studies of this issue in the elderly are rare. Objective To investigate the impact of self-reported rhinitis and asthma on sleep apnea and sleep quality using polysomnography in an elderly Korean population. Methods A total of 348 elderly subjects who underwent one-night polysomnography study among a randomly selected sample were enrolled. Study subjects underwent anthropometric and clinical evaluations. Simultaneously, the prevalence and co-morbid status of asthma and allergic rhinitis, and subjective sleep quality were evaluated using a self-reported questionnaire. Results Ever-diagnosis of allergic rhinitis was significantly more prevalent in subjects with SDB compared with those without SDB. Subjects with an ever-diagnosis of allergic rhinitis showed a higher O2 desaturation index and mean apnea duration. Indices regarding sleep efficiency were affected in subjects with a recent treatment of allergic rhinitis or asthma. Waking after sleep onset was longer and sleep efficiency was lower in subjects who had received allergic rhinitis treatment within the past 12 months. Subjects who had received asthma treatment within the past 12 months showed significantly lower sleep efficiency than others. Conclusion Our study indicates that a history of allergic rhinitis is associated with increased risk of SDB in the elderly. Sleep disturbance and impaired sleep efficiency were found in the subjects who had received recent treatment of allergic rhinitis or asthma. Physicians should be aware of the high risk of sleep disorders in older patients with respiratory allergic diseases. PMID:28245272

    Asthma is a common chronic disease characterized by bronchial inflammation, reversible airway obstruction, and airway hyperresponsiveness (AHR). Current therapeutic options for the management of asthma include inhaled corticosteroids and β2 agonists, which elicit harmful side effects. In the present study, we examined the capacity of phospholipase A2 (PLA2), one of the major components of bee venom (BV), to reduce airway inflammation and improve lung function in an experimental model of asthma. Allergic asthma was induced in female BALB/c mice by intraperitoneal administration of ovalbumin (OVA) on days 0 and 14, followed by intratracheal challenge with 1% OVA six times between days 22 and 30. The infiltration of immune cells, such as Th2 cytokines in the lungs, and the lung histology, were assessed in the OVA-challenged mice in the presence and absence of an intratracheal administration of bvPLA2. We showed that the intratracheal administration of bvPLA2 markedly suppressed the OVA-induced allergic airway inflammation by reducing AHR, overall area of inflammation, and goblet cell hyperplasia. Furthermore, the suppression was associated with a significant decrease in the production of Th2 cytokines, such as IL-4, IL-5, and IL-13, and a reduction in the number of total cells, including eosinophils, macrophages, and neutrophils in the airway.

    Full Text Available Background. Allergic asthma is showed an increase in Th2-cytokine and IgE levels and an accumulation activation of Th2 cells, eosinophils and mast cells. However, recent studies focused on cell-based mechanisms for the pathogenesis of allergic asthma. Objectives. In this study, we compare the anti-IgE treatment modality in the dynamics of immune system cytokine levels in severe persistent asthma (SPA patients who had no other any allergic disease, newly diagnosed allergic asthma patients and healthy volunteers. Study Design. The study population consisted of 14 SPA patients, 14 newly diagnosed allergic asthma patients and 14 healthy volunteers included as controls. Cytokine levels were measured. Total and specific IgE levels of anti-IgE monoclonal antibody treated patients, serum high-sensitivity C-reactive protein (hsCRP levels, FEV1/FVC rates and asthma control test (ACT were measured for the clinical follow-up. Results. We observed that SPA patients presented increasing levels of IL-8, IL-10, TGF-β and GCSF during the anti-IgE treatment in period of sampling times at 4 months and 18 months. However this increase was not correlated neither with serum hsCRP levels nor FEV1/FVC rates. Conclusions. Our study gives a different perspective for the SPA and anti-IgE immunotherapy efficacy at the cell cytokine-linked step.

    Full Text Available The prevalence of asthma and allergic diseases is rising worldwide. Evidence on potential causal pathways of asthma and allergies is growing, but findings have been contradictory, particularly on the interplay between allergic diseases and understudied social determinants of health like migration status. This review aimed at providing evidence for the association between migration status and asthma and allergies, and to explore the mechanisms between migration status and the development of asthma and allergies.Systematic review on asthma and allergies and immigration status in accordance with the guidelines set by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA statement. The pooled odds ratio (OR of the prevalence of asthma in immigrants compared to the host population was 0.60 (95% CI 0.45-0.84, and the pooled OR for allergies was 1.01 (95% CI 0.62-1.69. The pooled OR for the prevalence of asthma in first generation versus second generation immigrants was 0.37 (95% CI 0.25-0.58. Comparisons between populations in their countries of origin and those that emigrated vary depending on their level of development; more developed countries show higher rates of asthma and allergies.Our findings suggest a strong influence of the environment on the development of asthma and allergic diseases throughout the life course. The prevalence of asthma is generally higher in second generation than first generation immigrants. With length of residence in the host country the prevalence of asthma and allergic diseases increases steadily. These findings are consistent across study populations, host countries, and children as well as adults. Differences have been found to be significant when tested in a linear model, as well as when comparing between early and later age of migration, and between shorter and longer time of residence.

    Background The measure of fractional exhaled nitric oxide (FENO) in the airways is a useful tool to guide the diagnosis and titration of inhaled corticosteroids in patients with asthma. However, its role in diagnosis of allergic rhinitis (AR), especially in subjects with asthma, is not well established. Objective To study the cutoff of nasal FENO in the diagnosis of subjects with AR and AR-asthma compared to age-matched subjects without AR or asthma and its correlations with the clinical and functional characteristics. Methods The study was cross sectional and descriptive. Subjects were grouped into control subjects, AR, and AR-asthma, based on the inclusion criteria. Exhaled NO (nasal FENO, bronchial FENO, and alveolar concentration of NO) was measured by multiple flow electro-luminescence device. Results Six hundred twenty-eight subjects were included: 217 control subjects (children: n=98, 10±4 years; adults: n=119, 50±16 years), 168 subjects with AR (children: n=54, 10±3 years; adults: n=114, 49±15 years), and 243 subjects with AR-asthma (children: n=115, 10±3 years; adults: n=128, 51±14 years). Nasal peak inspiratory flow and peak expiratory flow were lower in subjects with AR and AR-asthma than in control subjects (P<0.01 and P<0.01; and P<0.05 and P<0.01, respectively). Nasal FENO levels were significantly higher in subjects with AR and AR-asthma than in control subjects (1614±629 and 1686±614 ppb vs 582±161 ppb; P<0.001 and P<0.001, respectively). In subjects with AR non-asthma, the cutoffs of nasal FENO for those diagnosed with AR were 775 ppb in children, 799 ppb in adults, and 799 in the general population (sensitivity: 92.68%, 92.63%, and 92.65%, respectively; specificity: 91.67%, 95.00%, and 96.87%, respectively). In subjects with AR-asthma, the cutoffs of nasal FENO were higher, especially in asthma children (1458 ppb; sensitivity: 72.97% and specificity: 95.83%). Conclusion Nasal FENO measurement is a useful technique for the diagnosis of AR

  1. Anti-malarial drug artesunate attenuates experimental allergic asthma via inhibition of the phosphoinositide 3-kinase/Akt pathway.

    Full Text Available BACKGROUND: Phosphoinositide 3-kinase (PI3K/Akt pathway is linked to the development of asthma. Anti-malarial drug artesunate is a semi-synthetic derivative of artemisinin, the principal active component of a medicinal plant Artemisia annua, and has been shown to inhibit PI3K/Akt activity. We hypothesized that artesunate may attenuate allergic asthma via inhibition of the PI3K/Akt signaling pathway. METHODOLOGY/PRINCIPAL FINDINGS: Female BALB/c mice sensitized and challenged with ovalbumin (OVA developed airway inflammation. Bronchoalveolar lavage fluid was assessed for total and differential cell counts, and cytokine and chemokine levels. Lung tissues were examined for cell infiltration and mucus hypersecretion, and the expression of inflammatory biomarkers. Airway hyperresponsiveness was monitored by direct airway resistance analysis. Artesunate dose-dependently inhibited OVA-induced increases in total and eosinophil counts, IL-4, IL-5, IL-13 and eotaxin levels in bronchoalveolar lavage fluid. It attenuated OVA-induced lung tissue eosinophilia and airway mucus production, mRNA expression of E-selectin, IL-17, IL-33 and Muc5ac in lung tissues, and airway hyperresponsiveness to methacholine. In normal human bronchial epithelial cells, artesunate blocked epidermal growth factor-induced phosphorylation of Akt and its downstream substrates tuberin, p70S6 kinase and 4E-binding protein 1, and transactivation of NF-κB. Similarly, artesunate blocked the phosphorylation of Akt and its downstream substrates in lung tissues from OVA-challenged mice. Anti-inflammatory effect of artesunate was further confirmed in a house dust mite mouse asthma model. CONCLUSION/SIGNIFICANCE: Artesunate ameliorates experimental allergic airway inflammation probably via negative regulation of PI3K/Akt pathway and the downstream NF-κB activity. These findings provide a novel therapeutic value for artesunate in the treatment of allergic asthma.

  2. Fullerene carbon-70 derivatives dampen anaphylaxis and allergic asthma pathogenesis in mice

    Norton, Sarah Brooke

    Fullerenes are carbon nanospheres that can be solublized by the addition of polar chemical groups to the carbon cage, forming fullerene derivatives. One specifically derivatized fullerene compound, termed C 70-Tetragylocolate (C70-TGA), has been shown to stabilize mast cell responses in vitro thus we hypothesized it may have an effect on mast cell-driven diseases such as asthma and systemic anaphylaxis. To observe the effects of C70-TGA on systemic anaphylaxis, mice were subjected to a model of passive systemic anaphylaxis. In this model, mice were injected with DNP-specific IgE 16 hours prior to challenge, then treated with C 70-TGA. Immediately prior to DNP challenge, mice were subjected to a second injection of C70-TGA. Following DNP challenge, body temperature was recorded and blood was collected for quantitation of histamine levels. Treatment with C70-TGA significantly reduced body temperature drop associated with systemic anaphylaxis and serum histamine levels. To observe the effects of C70-TGA on chronic features of asthma in vivo, we utilized a heavily MC influenced model of asthma pathogenesis. Mice were sensitized by intraperitoneal (i.p.) injection of ovalbumin (OVA) in saline, challenged intranasally (i.n.) with OVA, and one of two treatment strategies was pursued. In one, C70-TGA was given i.n. throughout disease development. In the other, C70-TGA was given following an initial set of challenges to allow disease to develop prior to treatment; mice were then re-challenged with OVA to assess the effect on established disease. We found that C70-TGA treatment significantly reduced airway inflammation and eosinophilia and dramatically reduced bronchoconstriction in either model. Cytokines IL-4 and IL-5 and serum IgE levels are significantly reduced in C70-TGA treated animals. Interestingly, we also saw an increase in the anti-inflammatory eicosanoid 11, 12-epoxyeicosatreinoic acid (11,12-EET) in the BAL fluid, suggesting the involvement of this mediator in

    Full Text Available Introduction This analysis was conducted with the objective of evaluating association between waterpipe passive smoking exposure and asthma, and allergies among Lebanese children. Material and methods Data were taken from a crosssectional study on children from public and private schools. A sample of 22 schools participated in the study, where standardized written core questionnaires were distributed. From 5 to 12-year-old students filled in the questionnaires at home, while 13–14-year-old students filled it in in the class. In total, 5522 children were evaluated for the prevalence of asthma, allergic rhinitis and atopic eczema, and their associated factors, including waterpipe exposure due to parents’ smoking. Results The descriptive results of parental smoking were, as follows: among mothers: 1609 (29% mothers smoked cigarettes, 385 (7% smoked waterpipe and 98 (1.8% smoked both; among fathers: 2449 (44.2% smoked cigarettes, 573 (10.3% smoked waterpipe and 197 (3.5% smoked both. Maternal waterpipe smoking was significantly and moderately associated with allergic diseases (p < 0.001; ORa = 1.71, including probable asthma, rhinitis and dermatitis (p < 0.001 for all. Quite on the opposite, father’s waterpipe smoking was not associated with any of the diseases. Parental cigarette smoking demonstrated some positive effects: father’s cigarette smoking did not show association with dermatitis or asthma diagnosed by a physician, while mother’s cigarette smoking showed a positive association only with probable asthma. Moreover, no interactions between cigarette and waterpipe smoking were observed. Conclusions Maternal waterpipe smoking should be regarded as a high risk behavior; however, additional studies are necessary to confirm this finding.

    Bronchial asthma is recognized as a highly prevalent health problem in the developed and developing world with significant social and economic consequences. Increased asthma severity is not only associated with enhanced recurrent hospitalization and mortality but also with higher social costs. The pathogenetic background of allergic-atopic bronchial asthma is characterized by airway inflammation with infiltration of several cells (mast cells, basophils, eosinophils, monocytes, and T-helper (Th)2 lymphocytes). However, in atopic asthma the trigger factors for acute attacks and chronic worsening of bronchial inflammation are aeroallergens released by pollens, dermatophagoides, and pets, which are able to induce an immune response by interaction with IgE antibodies. Currently anti-inflammatory treatments are effective for most asthma patients, but there are asthmatic subjects whose disease is not completely controlled by inhaled or systemic corticosteroids and who account for a significant portion of the healthcare costs of asthma. A novel therapeutic approach to asthma and other allergic respiratory diseases involves interference in the action of IgE, and this antibody has been viewed as a target for novel immunological drug development in asthma. Omalizumab is a humanized recombinant monoclonal anti-IgE antibody approved for treatment of moderate to severe IgE-mediated (allergic) asthma. This non-anaphylactogenic anti-IgE antibody inhibits IgE functions, blocking free serum IgE and inhibiting their binding to cellular receptors. By reducing serum IgE levels and IgE receptor expression on inflammatory cells in the context of allergic cascade, omalizumab represents a new class of mast cells stabilizing drugs; it is a novel approach to the treatment of atopic asthma. Omalizumab therapy is well tolerated and significantly improves symptoms and disease control, reducing asthma exacerbations and the need to use high dosage of inhaled corticosteroids. Moreover, omalizumab

    Pycnogenol® (PYC) is a standardized extracts from the bark of the French maritime pine (Pinus maritime) and used as a herbal remedy for various diseases. In this study, we evaluated the effects of PYC on airway inflammation using a model of ovalbumin (OVA)-induced allergic asthma and RAW264.7 cells. PYC decreased nitric oxide production and reduced the interleukine (IL)-1β and IL-6 levels in LPS-stimulated RAW264.7 cells. PYC also reduced the expression of inducible nitric oxide synthase (iNOS) and matrix metalloproteinase (MMP)-9 and enhanced the expression of hemeoxygenase (HO)-1. In the in vivo experiment, PYC decreased the inflammatory cell count and the levels of IL-4, IL-5, IL-13, and immunoglobulin (Ig) E in BALF or serum. These results are consistent with the histological analysis findings, which showed that PYC attenuated the airway inflammation and mucus hypersecretion induced by OVA challenge. In addition, PYC enhanced the expression of HO-1. In contrast, PYC inhibited the elevated expression of iNOS and MMP-9 proteins induced by OVA challenge. In conclusion, PYC exhibits protective effects against OVA-induced asthma and LPS-stimulated RAW264.7 cells. These results suggest that PYC has potential as a therapeutic agent for the treatment of allergic asthma.

    The prevalence of asthma and allergic responsiveness in rural and urban children of the highlands of Papua New Guinea was studied. Bronchial provocation studies with histamine demonstrated significant bronchial hyperreactivity in 0.5% (1 in 195) rural and 1.7% (1 in 59) urban children, rates which were significantly lower than those observed in corresponding adult populations (7%). Urban children demonstrated a higher incidence of skin test reactivity toward Dermatophagoides pteronyssinus, Aspergillus fumigatus, and dog dander than did the rural children. However, there were no significant differences between these populations with regard to total serum IgE levels, the degree of parasitism as judged by stool examination, or allergic responses to Ascaris suum, plantain, and coffee bean husk. A more detailed study demonstrated age- and sex-related differences in total IgE and mite-specific RAST scores in the rural but not the urban population. These data suggest an active suppression of the capacity of children to mount an IgE response to environmental allergens such as the mite manifesting itself as low asthma prevalence. The data also indicate that, although the underlying defect of bronchial hyperreactivity in asthma may be genetically inherited, it is not revealed until the lung has received an allergen-induced inflammatory insult.

    The primary focus in managing asthma is the control of inflammation, as asthma is an inflammatory disease. Because of this chronic airway inflammation, the lungs of asthmatic patients are exposed to oxidative stress due to the generation of reactive oxygen- and nitrogen species (ROS and NOS). Oxidative stress therefore plays an important role in…

    Maternal fish intake during pregnancy may influence the risk of child asthma and allergic rhinitis, yet evidence is conflicting on its association with these outcomes. We examined the associations of maternal fish intake during pregnancy with child asthma and allergic rhinitis. Mothers in the Danish National Birth Cohort (n 28 936) reported their fish intake at 12 and 30 weeks of gestation. Using multivariate logistic regression, we examined the associations of fish intake with child wheeze, asthma and rhinitis assessed at several time points: ever wheeze, recurrent wheeze (>3 episodes), ever asthma and allergic rhinitis, and current asthma, assessed at 18 months (n approximately 22,000) and 7 years (n approximately 17,000) using self-report and registry data on hospitalisations and prescribed medications. Compared with consistently high fish intake during pregnancy (fish as a sandwich or hot meal > or equal to 2-3 times/week), never eating fish was associated with a higher risk of child asthma diagnosis at 18 months (OR 1·30, 95% CI 1·05, 1·63, P=0·02), and ever asthma by hospitalisation (OR 1·46, 95% CI 0·99, 2·13, P=0·05) and medication prescription (OR 1·37, 95% CI 1·10, 1·71, P=0·01). A dose-response was present for asthma at 18 months only (P for trend=0·001). We found no associations with wheeze or recurrent wheeze at 18 months or with allergic rhinitis. The results suggest that high (v. no) maternal fish intake during pregnancy is protective against both early and ever asthma in 7-year-old children.

    2010-01-01

    This work reports the investigation of the effect of airway IL-4RA gene transfer by a recombinant retroviral vector on airway inflammation and airway responsiveness in asthmatic mice. The retrovirus-mediated delivery of IL-4RA to the airways of mice inhibited elevations of airway responsiveness and the development of allergic inflammation in asthmatic mice, and regulated the Th1/Th2 balance in OVA-sensitized and -challenged mouse models. This suggests that gene therapy is a therapeutic option for treating and controlling chronic airway inflammation and asthma symptoms.

    We investigated prevalence and determinants of asthma and allergic diseases in a cross-sectional survey of schoolchildren aged 6-14 in 2002. This was the third of a series of cross-sectional surveys, conducted in 1992 and 1997, in the same school in Ankara, Turkey. Questionnaire including information on house characteristics, dietary habits, past and current exposures and diseases were distributed to 1064 children (523 boys, 541 girls) and filled by the parents at home. Percentage of children having a pet was significantly higher (1992: 7.9, 1997: 22.9, 2002: 21), but that of passive smoking was significantly lower (1992: 74, 1997: 64, 2002: 64.1) in 1997 and 2002 when compared with 1992. Current prevalence percentage of asthma (1992: 8.3, 1997: 9.8, 2002: 6.4), wheeze (1992: 11.9, 1997: 13.3, 2002: 6.4), hay fever (1992: 15.4, 1997: 14.1, 2002: 7.2), and eczema (1992: 4, 1997: 4.3, 2002: 1.8) were significantly lower in 2002 compared with 1992. Multiple logistic regression analysis model for current wheeze included ingestion of cow's milk (no regular ingestion: reference, ORs and 95% CIs, dog (6.1, 1.6-23.4). Multiple logistic regression analysis model for current hay fever included ingestion of red meat (1.8, 1.1-2.9) and father's education (none of the parents finished secondary school: reference, secondary school to university: 0.5, 0.2-1.0). Our findings suggested that current prevalence of asthma and allergic diseases decreased among schoolchildren in Ankara, in the last 10 yr, and ingestion of milk and red meat could have a role in the occurrence of asthma and hay fever. Detailed assessment of dietary habits is required to test this hypothesis.

The correction of immune response by these cells should be considered in the prevention and treatment of asthma. Native antigen 85B (Ag85B of mycobacteria, which cross-reacts among mycobacteria species, may play an important biological role in host–pathogen interaction since it elicits various immune responses by activation of Th cells. The current study investigated the antiallergic inflammatory effects of DNA administration of Ag85B from Mycobacterium kansasii in a mouse model of asthma. Immunization of BALB/c mice with alum-adsorbed ovalbumin followed by aspiration with aerosolized ovalbumin resulted in the development of allergic airway inflammation. Administration of Ag85B DNA before the aerosolized ovalbumin challenge protected the mice from subsequent induction of allergic airway inflammation. Serum and bronchoalveolar lavage immunoglobulin E levels, extent of eosinophil infiltration, and levels of Th2-type cytokines in Ag85B DNA-administered mice were significantly lower than those in control plasmid-immunized mice, and levels of Th1- and T-regulatory-type cytokines were enhanced by Ag85B

    Allergic airway disorder is characterized by an increase in the level of reactive oxygen species (ROS). The induction of inflammation and hyperresponsiveness by an allergen was ameliorated by antioxidants in vivo. This study investigated the protective effects and underlying mechanism of diallyl sulfide (DAS) on ovalbumin (OVA)-induced allergic asthma of BALB/c mice. The animals were intraperitoneally sensitized by inhaling OVA to induce chronic airway inflammation. By administering DAS, a decrease of the infiltrated inflammatory cell counts and the levels of IL-4 and IL-10 in bronchoalveolar lavage fluid as well as the OVA-specific immunoglobulin E levels in sera were observed. DAS also effectively inhibited OVA-induced inflammatory cell infiltration and mucus hypersecretion in lung tissue. Several OVA-induced inflammatory factors (ROS, 8-hydroxy-2'-deoxyguanosine, 8-iso-prostaglandin F2α, and NF-κB) were inhibited by DAS. In addition, DAS increased OVA inhalation-reduced levels of Nrf2 activation by regulating microRNA-144, -34a and -34b/c. Together, the pathogenesis of OVA-induced asthma is highly associated with oxidative stress, and DAS may be an effective supplement to alleviate this disease.

    Full Text Available Abstract Background While it is suggested that the prevalence of asthma in developed countries may have stabilized, this is not clear in currently developing countries. Current available information for both adults and children simultaneously on the burden and impact of allergic conditions in Colombia and in many Latin American countries is limited. The objectives of this study were to estimate the prevalence for asthma, allergic rhinitis (AR, atopic eczema (AE, and atopy in six colombian cities; to quantify costs to the patient and her/his family; and to determine levels of Immunoglobulin E (IgE in asthmatic and healthy subjects. Methods We conducted a cross-sectional, population-based study in six cities during the academic year 2009–2010. We used a school-based design for subjects between 5–17 years old. We carried out a community-based strategy for subjects between 1–4 years old and adults between 18–59 years old. Serum samples for total and antigen-specific (IgE levels were collected using a population-based, nested, case–control design. Results We obtained information on 5978 subjects. The largest sample of subjects was collected in Bogotá (2392. The current prevalence of asthma symptoms was 12% (95% CI, 10.5-13.7, with 43% (95% CI, 36.3-49.2 reporting having required an emergency department visit or hospitalization in the past 12 months. Physician diagnosed asthma was 7% (95% CI, 6.1-8.0. The current prevalence of AR symptoms was 32% (95% CI, 29.5-33.9, and of AE symptoms was 14% (95% CI, 12.5-15.3.

    Mouse models have provided a significant insight into the role of T-helper (Th) 2 cytokines such as IL-5 and IL-13 in regulating eosinophilia and other key features of asthma. However, the validity of these models can be compromised by inadvertent infection of experimental mouse colonies with pathogens such as oxyurid parasites (pinworms). While the benzimidazole derivative, fenbendazole (FBZ), is commonly used to treat such outbreaks, the effects of FBZ on mouse models of Th2 disease are largely unknown. In this investigation, we show that mice fed FBZ-supplemented food during the in utero and post-weaning period developed attenuated lung eosinophilia, antigen-specific IgG1 and Th2 cytokine responses in a model of asthma. Treatment of the mediastinal lymph node cells from allergic mice with FBZ in vitro attenuated cell proliferation, IL-5 and IL-13 production and expression of the early lymphocyte activation marker, CD69 on CD4(+) T cells and CD19(+) B cells. In addition, eosinophilia and Th2 responses remained attenuated after a 4-week withholding period in allergic mice treated preweaning with FBZ. Thus, FBZ modulates the amplitude of Th2 responses both in vivo and in vitro.

    Full Text Available Discoveries from basic science research in the last decade have brought significant progress in knowledge of pathophysiologic processes of allergic diseases, with a compelling impact on understanding of the natural history, risk prediction, treatment selection or mechanism-specific prevention strategies. The view of the pathophysiology of allergic diseases developed from a mechanistic approach, with a focus on symptoms and organ function, to the recognition of a complex network of immunological pathways. Several subtypes of inflammation and complex immune-regulatory networks and the reasons for their failure are now described, that open the way for the development of new diagnostic tools and innovative targeted-treatments. An endotype is a subtype of a disease condition, which is defined by a distinct pathophysiological mechanism, whereas a disease phenotype defines any observable characteristic of a disease without any implication of a mechanism. Another key word linked to disease endotyping is biomarker that is measured and evaluated to examine any biological or pathogenic processes, including response to a therapeutic intervention. These three keywords will be discussed more and more in the future with the upcoming efforts to revolutionize patient care in the direction of precision medicine and precision health. The understanding of disease endotypes based on pathophysiological principles and their validation across clinically meaningful outcomes in asthma, allergic rhinitis, chronic rhinosinusitis, atopic dermatitis and food allergy will be crucial for the success of precision medicine as a new approach to patient management.

    Mannan-binding lectin (MBL), an important component of innate immunity, binds to a range of foreign antigens and initiates the lectin complement pathway. Earlier studies have reported high plasma MBL levels in allergic patients in comparison to healthy controls. In view of varied plasma MBL levels...... being determined by genetic polymorphisms in its collagen region, we investigated the association of single nucleotide polymorphisms (SNPs) in the collagen region of human MBL with respiratory allergic diseases. The study groups comprised patients of bronchial asthma with allergic rhinitis (n = 49......) and allergic bronchopulmonary aspergillosis (APBA) (n = 11) and unrelated age-matched healthy controls of Indian origin (n = 84). A novel intronic SNP, G1011A of MBL, showed a significant association with both the patient groups in comparison to the controls (P

    Asthma is prevalent in children and cats, and needs means of noninvasive diagnosis. We sought to distinguish noninvasively the differences in 53 cats before and soon after induction of allergic asthma, using NMR spectra of exhaled breath condensate (EBC). Statistical pattern recognition was improved considerably by preprocessing the spectra with probabilistic quotient normalization and glog transformation. Classification of the 106 preprocessed spectra by principal component analysis and partial least squares with discriminant analysis (PLS-DA) appears to be impaired by variances unrelated to eosinophilic asthma. By filtering out confounding variances, orthogonal signal correction (OSC) PLS-DA greatly improved the separation of the healthy and early asthmatic states, attaining 94% specificity and 94% sensitivity in predictions. OSC enhancement of multi-level PLS-DA boosted the specificity of the prediction to 100%. OSC-PLS-DA of the normalized spectra suggest the most promising biomarkers of allergic asthma in cats to include increased acetone, metabolite(s) with overlapped NMR peaks near 5.8 ppm, and a hydroxyphenyl-containing metabolite, as well as decreased phthalate. Acetone is elevated in the EBC of 74% of the cats with early asthma. The noninvasive detection of early experimental asthma, biomarkers in EBC, and metabolic perturbation invite further investigation of the diagnostic potential in humans. PMID:27764146

    Asthma is characterized by aberrant airways including epithelial thickening, goblet cell hyperplasia, and smooth muscle hypertrophy within the airway wall. The current study examined whether kaempferol inhibited mast cell degranulation and prostaglandin (PG) release leading to the development of aberrant airways, using an in vitro model of dinitrophenylated bovine serum albumin (DNP-BSA)-sensitized rat basophilic leukemia (RBL-2H3) mast cells and an in vivo model of BSA-challenged asthmatic mice. Nontoxic kaempferol at 10-20 μM suppressed β-hexosaminidase release and cyclooxygenase 2 (COX2)-mediated production of prostaglandin D2 (PGD2) and prostaglandin F2α (PGF2α) in sensitized mast cells. Oral administration of ≤20 mg/kg kaempferol blocked bovine serum albumin (BSA) inhalation-induced epithelial cell excrescence and smooth muscle hypertrophy by attenuating the induction of COX2 and the formation of PGD2 and PGF2α, together with reducing the anti-α-smooth muscle actin (α-SMA) expression in mouse airways. Kaempferol deterred the antigen-induced mast cell activation of cytosolic phospholipase A2 (cPLA2) responsive to protein kinase Cμ (PKCμ) and extracellular signal-regulated kinase (ERK). Furthermore, the antigen-challenged activation of Syk-phospholipase Cγ (PLCγ) pathway was dampened in kaempferol-supplemented mast cells. These results demonstrated that kaempferol inhibited airway wall thickening through disturbing Syk-PLCγ signaling and PKCμ-ERK-cPLA2-COX2 signaling in antigen-exposed mast cells. Thus, kaempferol may be a potent anti-allergic compound targeting allergic asthma typical of airway hyperplasia and hypertrophy.

  7. Does traffic exhaust contribute to the development of asthma and allergic sensitization in children: findings from recent cohort studies

    Full Text Available Abstract The aim of this review was to assess the evidence from recent prospective studies that long-term traffic pollution could contribute to the development of asthma-like symptoms and allergic sensitization in children. We have reviewed cohort studies published since 2002 and found in PubMed in Oct 2008. In all, 13 papers based on data from 9 cohorts have evaluated the relationship between traffic exposure and respiratory health. All surveys reported associations with at least some of the studied respiratory symptoms. The outcome varied, however, according to the age of the child. Nevertheless, the consistency in the results indicates that traffic exhaust contributes to the development of respiratory symptoms in healthy children. Potential effects of traffic exhaust on the development of allergic sensitization were only assessed in the four European birth cohorts. Long-term exposure to outdoor air pollutants had no association with sensitization in ten-year-old schoolchildren in Norway. In contrast, German, Dutch and Swedish preschool children had an increased risk of sensitization related to traffic exhaust despite fairly similar levels of outdoor air pollution as in Norway. Traffic-related effects on sensitization could be restricted to individuals with a specific genetic polymorphism. Assessment of gene-environment interactions on sensitization has so far only been carried out in a subgroup of the Swedish birth cohort. Further genetic association studies are required and may identify individuals vulnerable to adverse effects from traffic-related pollutants. Future studies should also evaluate effects of traffic exhaust on the development and long term outcome of different phenotypes of asthma and wheezing symptoms.

    There is evidence that allergy to common indoor pets, particularly cats and dogs, is closely associated with symptomatic asthma in the United States. Because the presence of pets in a home is a potentially modifiable factor, it is important to consider how much asthma morbidity and health care cost might be alleviated by the removal of pets from the homes of all persons with pet-allergic asthma. The percentage of pet-associated excess asthma morbidity was estimated as a proportion of all asthma-related health care costs for the United States.

    The prevalence of allergic airway diseases such as asthma and rhinitis has increased dramatically to epidemic proportions worldwide. Besides air pollution from industry derived emissions and motor vehicles, the rising trend can only be explained by gross changes in the environments where we live. The world economy has been transformed over the last 25 years with developing countries being at the core of these changes. Around the planet, in both developed and developing countries, environments are undergoing profound changes. Many of these changes are considered to have negative effects on respiratory health and to enhance the frequency and severity of respiratory diseases such as asthma in the general population. Increased concentrations of greenhouse gases, and especially carbon dioxide (CO2), in the atmosphere have already warmed the planet substantially, causing more severe and prolonged heat waves, variability in temperature, increased air pollution, forest fires, droughts, and floods - all of which can put the respiratory health of the public at risk. These changes in climate and air quality have a measurable impact not only on the morbidity but also the mortality of patients with asthma and other respiratory diseases. The massive increase in emissions of air pollutants due to economic and industrial growth in the last century has made air quality an environmental problem of the first order in a large number of regions of the world. A body of evidence suggests that major changes to our world are occurring and involve the atmosphere and its associated climate. These changes, including global warming induced by human activity, have an impact on the biosphere, biodiversity, and the human environment. Mitigating this huge health impact and reversing the effects of these changes are major challenges. This statement of the World Allergy Organization (WAO) raises the importance of this health hazard and highlights the facts on climate-related health impacts

    Background Cyclic AMP (cAMP) signaling modulates functions of inflammatory cells involved in the pathogenesis of asthma, and type 4 cAMP-specific phosphodiesterases (PDE4s) are essential components of this pathway. Induction of the PDE4 isoform PDE4B is necessary for Toll-like receptor signaling in monocytes and macrophages and is associated with T cell receptor/CD3 in T cells; however, its exact physiological function in the development of allergic asthma remains undefined. Objectives We investigated the role of PDE4B in the development of allergen-induced airway hyperresponsiveness (AHR) and TH2-driven inflammatory responses. Methods Wild-type and PDE4B−/− mice were sensitized and challenged with ovalbumin and AHR measured in response to inhaled methacholine. Airway inflammation was characterized by analyzing leukocyte infiltration and cytokine accumulation in the airways. Ovalbumin-stimulated cell proliferation and TH2 cytokine production were determined in cultured bronchial lymph node cells. Results Mice deficient in PDE4B do not develop AHR. This protective effect was associated with a significant decrease in eosinophils recruitment to the lungs and decreased TH2 cytokine levels in the bronchoalveolar lavage fluid. Defects in T-cell replication, TH2 cytokine production, and dendritic cell migration were evident in cells from the airway-draining lymph nodes. Conversely, accumulation of the TH1 cytokine IFN-γ was not affected in PDE4B−/− mice. Ablation of the orthologous PDE4 gene PDE4A has no impact on airway inflammation. Conclusion By relieving a cAMP-negative constraint, PDE4B plays an essential role in TH2-cell activation and dendritic cell recruitment during airway inflammation. These findings provide proof of concept that PDE4 inhibitors with PDE4B selectivity may have efficacy in asthma treatment. PMID:21047676

    Full Text Available BACKGROUND: Males and females exhibit different health responses to air pollution, but little is known about how exposure to air pollution affects juvenile respiratory health after analysis stratified by allergic predisposition. The aim of the present study was to assess the relationship between air pollutants and asthmatic symptoms in Chinese children selected from multiple sites in a heavily industrialized province of China, and investigate whether allergic predisposition modifies this relationship. METHODOLOGY/PRINCIPAL FINDINGS: 30139 Chinese children aged 3-to-12 years were selected from 25 districts of seven cities in northeast China in 2009. Information on respiratory health was obtained using a standard questionnaire from the American Thoracic Society. Routine air-pollution monitoring data was used for particles with an aerodynamic diameter ≤10 µm (PM(10, sulfur dioxide (SO(2, nitrogen dioxides (NO(2, ozone (O(3 and carbon monoxide (CO. A two-stage regression approach was applied in data analyses. The effect estimates were presented as odds ratios (ORs per interquartile changes for PM(10, SO(2, NO(2, O(3, and CO. The results showed that children with allergic predisposition were more susceptible to air pollutants than children without allergic predisposition. Amongst children without an allergic predisposition, air pollution effects on asthma were stronger in males compared to females; Current asthma prevalence was related to PM(10 (ORs = 1.36 per 31 µg/m(3; 95% CI, 1.08-1.72, SO(2 (ORs = 1.38 per 21 µg/m(3; 95%CI, 1.12-1.69 only among males. However, among children with allergic predisposition, more positively associations between air pollutants and respiratory symptoms and diseases were detected in females; An increased prevalence of doctor-diagnosed asthma was significantly associated with SO(2 (ORs = 1.48 per 21 µg/m(3; 95%CI, 1.21-1.80, NO(2 (ORs = 1.26 per 10 µg/m(3; 95%CI, 1.01-1.56, and current asthma with

    Fulvio Braido

    Full Text Available OBJECTIVES: Asthma trials suggest that patients reaching total disease control have an optimal Health Related Quality of Life (HRQoL. Moreover, rhinitis is present in almost 80% of asthmatics and impacts asthma control and patient HRQoL. We explored whether optimal HRQoL was reachable in a real-life setting, and evaluated the disease and patient related patterns associated to optimal HRQoL achievement. METHODS AND FINDINGS: Asthma and rhinitis HRQoL, illness perception, mood profiles, rhinitis symptoms and asthma control were assessed by means of validated tools in patients classified according to GINA and ARIA guidelines. Optimal HRQoL, identified by a Rhinasthma Global Summary (GS score ≤20 (score ranging from 0 to 100, where 100 represents the worst possible HRQoL, was reached by 78/209 (37.32%. With the exception of age, no associations were found between clinical and demographic characteristics and optimal HRQoL achievement. Patients reaching an optimal HRQoL differed in disease perception and mood compared to those not reaching an optimal HRQoL. Asthma control was significantly associated with optimal HRQoL (χ(2 = 49.599; p<0.001 and well-controlled and totally controlled patients significantly differed in achieving optimal HRQoL (χ(2 = 7.617; p<0.006. CONCLUSION: Approximately one third of the patients in our survey were found to have an optimal HRQoL. While unsatisfactory disease control was the primary reason why the remainder failed to attain optimal HRQoL, it is clear that illness perception and mood also played parts. Therefore, therapeutic plans should be directed not only toward achieving the best possible clinical control of asthma and comorbid rhinitis, but also to incorporating individualized elements according to patient-related characteristics.

    Background Allergen-specific immunotherapy can induce immune tolerance to specific allergens by regulating immune status of individuals. However, its clinical application is limited due to individual differences in efficacy among patients and un-confirmed safety. 1,25 Dihydroxyvitamin D3 (1,25(OH)2D3) has been shown to be involved in a variety of physiological processes, including immune response regulation. In the present study we explored the role of 1,25(OH)2D3 pretreatment for immunotherapy.Methods Seventy-five BALB/c mice were randomly divided into five groups (15 mice per group). The mouse allergic asthma model was established by intra-peritoneal injection of ovalbumin (OVA, 10 μg) and aluminium hydroxide (2 mg)as an adjuvant. Intra-peritoneal injection of 50 ng of 1,25(OH)2D3 served as a pretreatment, subcutaneous injection of OVA (100 μg) as an immunotherapy, and 1% OVA inhalation as a challenge. Histopathological analysis was performed on four mice per group. The number of cells and their classification in bronchoalvolar lavage (BAL) fluid were assayed.Levels of serum OVA-specific immunoglobulin E (slgE) and IFN-Y, IL-4, IL-5 and IL-10 in BAL fluid were measured by ELISA.Results After 1,25(OH)2D3 pretreatment, immunotherapy could significantly inhibit the infiltration of inflammatory cells into lung tissues and BAL fluid of mice with allergic asthma when compared with un-treated animals (eosinophils:(7.46±1.34)×104/ml vs. (13.41±1.67)×104/ml, P <0.05). In addition, levels of IL-4 ((36.g1±7.87) pg/ml vs. (43.70±6.42)pg/ml, P >0.05) and IL-5 ((41.97±7.93) pg/ml vs. (60.14±8.35) pg/ml, P <0.05) in BAL fluid and serum slgE ((0.42±0.05)vs. (0.75±0.06) OD units, P <0.05) were profoundly reduced. However, the IL-10 level in BAL fluid was significantly increased ((67.74±6.57) pg/ml vs. (44.62±8.81) pg/ml, P <0.05).Conclusions These results indicated that 1,25(OH)2D3 pretreatment enhanced the inhibitory effects of immunotherapy on allergic

    ObjectiveTo investigate whether recuperating lung decoction (RLD) can modulate the composition of gut microbiota in rats during asthma treatment. MethodsFifteen Sprague-Dawley rats were divided randomly and equally into control group, model group, dexamethasone (DEX) group, RLD medium-dose group, and RLD high-dose group. The asthma model was established in all groups, except for the control group. The rats in the DEX and RLD groups were treated orally with DEX and RLD, respectively. The rats in the control and model groups were treated orally with 0.9% saline. The intestinal bacterial communities were compared among groups using 16S rRNA gene amplification and 454 pyrosequencing. ResultsThe microbial flora differed between the control and model groups, but the flora in the RLD groups was similar to that in the control group. No significant differences were observed between the RLD high-dose and medium-dose groups. RLD treatment resulted in an increase in the level beneficial bacteria in the gut, such asLactobacillusandBifidobacteriumspp. ConclusionOral administration of RLD increased the number of intestinal lactic acid-producing bacteria, such as Lactobacillus andBifidobacterium, in asthma model rats.

    Full Text Available The ultimate aim of immunology is to kill the pathogen without being harmful to the host. But what if eliminating the pathogen in itself is discomforting for the host? One such emerging case is of Helicobacter pylori. Modern medicine, infantile vaccination and ultra-hygienic conditions have led to progressive disappearance of H. pylori in different parts of the world. However, the adversities caused by H. pylori’s absence are much larger than those caused by its presence. Asthma is rising as an epidemic in last few decades and several reports suggest an inverse-relationship between H. pylori’s persistence and early-life onset asthma. Regulatory T cells play an important role in both the cases. This is further supported by experiments on mouse-models. Hence, need of the hour is to discern the relationship between H. pylori and its host and eliminating its negative impacts without disturbing our indigenous microbiota. To resolve whether H. pylori is a pathogen or an amphibiont is another important side. This review explores the biological basis of H. pylori-induced priming of immune system offering resistance to childhood-onset asthma. HP-NAP-Tregs interaction has been predicted using molecular docking and dynamic simulation.

    Full Text Available Abstract Background There is little information on potential differences in animal exposure between Finland and Russia and particularly on the effects of animal exposure on asthma among Russian children. The aim of the study was to compare the pet and farm animal exposures and to assess the relations of pre- and postnatal animal exposures to the occurrence of allergic asthma in Finnish and Russian school children. Methods We conducted a population-based cross-sectional study in neighbour towns on either side of the Finnish-Russian border; Imatra in Finland and Svetogorsk in Russia. The study population consisted of 512 Finnish and 581 Russian school children aged 7–16 years (response rate 79%. Multivariate logistic regression analysis was used to estimate adjusted odds ratios (OR and 95% confidence intervals (CI related to each exposure. Results Current indoor exposure to pets was more frequent among school children in Svetogorsk than in Imatra (67.5% vs. 56.0%, P Conclusion Exposure to pets and farm animals during childhood differed significantly between Finland and Russia. Our study provides evidence that early-life exposure to cats increases the risk of asthma whereas exposure to dogs is protective. Our findings suggest that intermittent fetal and early-life exposure to farm animals increases the risk of allergic asthma in urban children visiting farms.

    Full Text Available Two foundational methods for estimating the total economic burden of disease are cost of illness (COI and willingness to pay (WTP. WTP measures the full cost to society, but WTP estimates are difficult to compute and rarely available. COI methods are more often used but less likely to reflect full costs. This paper attempts to estimate the full economic cost (2014$ of illnesses resulting from exposure to dampness and mold using COI methods and WTP where the data is available. A limited sensitivity analysis of alternative methods and assumptions demonstrates a wide potential range of estimates. In the final estimates, the total annual cost to society attributable to dampness and mold is estimated to be $3.7 (2.3–4.7 billion for allergic rhinitis, $1.9 (1.1–2.3 billion for acute bronchitis, $15.1 (9.4–20.6 billion for asthma morbidity, and $1.7 (0.4–4.5 billion for asthma mortality. The corresponding costs from all causes, not limited to dampness and mold, using the same approach would be $24.8 billion for allergic rhinitis, $13.5 billion for acute bronchitis, $94.5 billion for asthma morbidity, and $10.8 billion for asthma mortality.

    The incidence of atopic conditions has increased in industrialized countries. Persisting symptoms and concern for drug side-effects lead patients toward adjunctive treatments such as phytotherapy. Previously, we have shown that Bromelain (sBr), a mixture of cysteine proteases from pineapple, Ananas comosus, inhibits ovalbumin (OVA)-induced murine model of allergic airway disease (AAD). However, sBr's effect on development of AAD when treatment is administered throughout OVA-alum sensitization was unknown and is the aim of the present study. C57BL/6J mice were sensitized with OVA/alum and challenged with 7 days OVA aerosol. sBr 6 mg/kg/0.5 ml or PBS vehicle were administered throughout sensitization. Lung, bronchoalveolar lavage (BAL), spleen, and lymph nodes were processed for flow cytometry and OVA-specific IgE was determined via ELISA. sBr treatment throughout OVA-alum sensitization significantly reduced the development of AAD (BAL eosinophils and lymphocytes). OVA-specific IgE and OVA TET(+) cells were decreased. sBr reduced CD11c(+) dendritic cell subsets, and in vitro treatment of DCs significantly reduced CD44, a key receptor in both cell trafficking and activation. sBr was shown to reduce allergic sensitization and the generation of AAD upon antigen challenge. These results provide additional insight into sBr's anti-inflammatory and antiallergic properties and rationale for translation into the clinical arena.

    2011-06-01

    Nematode infections such as Ascariasis are important health problems in underdeveloped countries, most of them located in the tropics where environmental conditions also promote the perennial co-exposure to high concentrations of domestic mite allergens. Allergic diseases are common, and most of patients with asthma exhibit a predominant and strong IgE sensitization to mites. It is unknown whether co-exposure to Ascaris lumbricoides and the domestic mites Blomia tropicalis and Dermatophagoides pteronyssinus potentiates Th2 responses and IgE sensitization, thereby modifying the natural history of allergy. Recently, we obtained experimental evidence of a high cross-reactivity between the allergenic extracts of these invertebrates, involving well-known allergens such as tropomyosin and glutathione transferases. There is indirect evidence suggesting that the clinical impact of these findings may be important. In this review, we discuss the potential role of this cross-reactivity on several aspects of allergy in the tropics that have been a focus of a number of investigations, some of them with controversial results.

    Full Text Available The efficiency of treatment of patients with allergic rhinitis and associated bronchial asthma by physical factors and advisability of two-stage treatment are justified. Sixty six patients were observed. The conclusion on the efficiency of treatment was based on the data about the dynamics clinical state of the primary and associated diseases, intensity of inflammation activity in respiratory tract (rhinocytograms, biochemical indices of nasal lavages, level of nitrogen oxide in expired air were studied, patency of airways (manometry, spirography. We compared two versions of treatment: two- and one-stage. Patients of the first group (30 patients received elimination therapy for 3 to 5 days with the following peaty mud application, current of supersonic frequency, massage, inhalations, physical therapy. Patients of the second group (36 patients did not receive elimination therapy. We have found a decrease in intensity of clinical implications of the primary and associated diseases, decrease in inflammation activity, better nasal and bronchial носовой patency, improvement of the mucociliary function in patients of the first group. In the second group, the recovery of the surface epithelium and nasal patency was not observed against the background of improvement of the clinical state.

  9. Neutralization of TSLP inhibits airway remodeling in a murine model of allergic asthma induced by chronic exposure to house dust mite.

    Directory of Open Access Journals (Sweden)

    Zhuang-Gui Chen

    Full Text Available Chronic allergic asthma is characterized by Th2-typed inflammation, and contributes to airway remodeling and the deterioration of lung function. However, the initiating factor that links airway inflammation to remodeling is unknown. Thymic stromal lymphopoietin (TSLP, an epithelium-derived cytokine, can strongly activate lung dendritic cells (DCs through the TSLP-TSLPR and OX40L-OX40 signaling pathways to promote Th2 differentiation. To determine whether TSLP is the underlying trigger of airway remodeling in chronic allergen-induced asthma, we induced allergic airway inflammation in mice by intranasal administration of house dust mite (HDM extracts for up to 5 consecutive weeks. We showed that repeated respiratory exposure to HDM caused significant airway eosinophilic inflammation, peribronchial collagen deposition, goblet cell hyperplasia, and airway hyperreactivity (AHR to methacholine. These effects were accompanied with a salient Th2 response that was characterized by the upregulation of Th2-typed cytokines, such as IL-4 and IL-13, as well as the transcription factor GATA-3. Moreover, the levels of TSLP and transforming growth factor beta 1 (TGF-β1 were also increased in the airway. We further demonstrated, using the chronic HDM-induced asthma model, that the inhibition of Th2 responses via neutralization of TSLP with an anti-TSLP mAb reversed airway inflammation, prevented structural alterations, and decreased AHR to methacholine and TGF-β1 level. These results suggest that TSLP plays a pivotal role in the initiation and persistence of airway inflammation and remodeling in the context of chronic allergic asthma.

    Full Text Available Abstract Asthma is the most common respiratory disorder in Canada. Despite significant improvement in the diagnosis and management of this disorder, the majority of Canadians with asthma remain poorly controlled. In most patients, however, control can be achieved through the use of avoidance measures and appropriate pharmacological interventions. Inhaled corticosteroids (ICSs represent the standard of care for the majority of patients. Combination ICS/long-acting beta2-agonists (LABA inhalers are preferred for most adults who fail to achieve control with ICS therapy. Allergen-specific immunotherapy represents a potentially disease-modifying therapy for many patients with asthma, but should only be prescribed by physicians with appropriate training in allergy. Regular monitoring of asthma control, adherence to therapy and inhaler technique are also essential components of asthma management. This article provides a review of current literature and guidelines for the appropriate diagnosis and management of asthma.

    Full Text Available Allergy is often accompanied by infections and lower levels of antimicrobial peptides (AMPs. Vitamin D has been shown to increase expression of selected AMPs. In this study we investigated whether antimicrobial peptide levels in nasal secretions of allergic asthma patients are lower than in healthy controls, and whether administration of the active form of vitamin D (1,25(OH2D3 affects these antimicrobial peptide levels.The levels of antimicrobial peptides in nasal secretions were compared between 19 allergic asthma patients and 23 healthy controls. The effect of seven days daily oral treatment with 2 μg 1,25(OH2D3 on antimicrobial peptides in nasal secretions was assessed in a placebo-controlled cross-over clinical study.Levels of neutrophil α-defensins (human neutrophil peptides 1-3; HNP1-3 and lipocalin 2 (LCN2; also known as NGAL were significantly lower in asthmatics, but no differences in LL-37 and SLPI were detected. Treatment with a short-term 1,25(OH2D3 caused a small increase in HNP1-3, but not when the asthma and control groups were analyzed separately. LL-37, LCN2 and SLPI did not change after treatment with 1,25(OH2D3.Levels of the antimicrobial peptides HNP1-3 and LCN2 are lower in nasal secretions in asthmatics and are not substantially affected by a short-term treatment with active vitamin D.

    Full Text Available Objective. Utilizing a food allergy murine model, we have investigated the intrinsic antiallergic potential of the Lactococcus lactis NCC 2287 strain. Methods. BALB/c mice were sensitized at weekly intervals with ovalbumin (OVA plus cholera toxin (CT by the oral route for 7 weeks. In this model, an oral challenge with a high dose of OVA at the end of the sensitization period leads to clinical symptoms. Lactococcus lactis NCC 2287 was given to mice via the drinking water during sensitization (prevention phase or after sensitization (management phase. Results. Lactococcus lactis NCC 2287 administration to sensitized mice strikingly reduced allergic manifestations in the management phase upon challenge, when compared to control mice. No preventive effect was observed with the strain. Lactococcus lactis NCC 2287 significantly decreased relative expression levels of the Th-2 cytokine, IL-13, and associated chemokines CCL11 (eotaxin-1 and CCL17 (TARC in the ileum. No effect was observed in the jejunum. Conclusion/Significance. These results taken together designate Lactococcus lactis NCC 2287 as a candidate probiotic strain appropriate in the management of allergic symptoms.

    Full Text Available Urokinase plasminogen activator (uPA and its inhibitor (PAI-1 have been associated with asthma. The aim of this study was to evaluate concentration of uPA and PAI-1 in induced sputum of house dust mite allergic asthmatics (HDM-AAs. The study was performed on 19 HDM-AAs and 8 healthy nonatopic controls (HCs. Concentration of uPA and PAI-1 was evaluated in induced sputum supernatants using ELISA method. In HDM-AAs the median sputum concentration of uPA (128 pg/ml; 95% CI 99 to 183 pg/ml and PAI-1 (4063 pg/ml; 95%CI 3319 to 4784 pg/ml were significantly greater than in HCs (17 pg/ml; 95%CI 12 to 32 pg/ml; p<0.001 and 626 pg/ml; 95%CI 357 to 961 pg/ml; p<0.001 for uPA and PAI-1 respectively. The sputum concentration of uPA correlated with sputum total cell count (r=0.781; p=0.0001 and with logarithmically transformed exhaled nitric oxide concentration (eNO (r=0.486; p=0.035 but not with FEV1 or bronchial reactivity to histamine. On the contrary, the sputum PAI-1 concentration correlated with FEV1 (r=-0,718; p=0.0005 and bronchial reactivity to histamine expressed as log(PC20 (r=-0.824; p<0.0001 but did not correlate with sputum total cell count or eNO. The results of this study support previous observations linking PAI-1 with airway remodeling and uPA with cellular inflammation. Moreover, the observed effect of uPA seems to be independent of its fibrynolytic activity.

    Mushrooms can break down complex plant materials into smaller, more digestible and bioactive compounds. The present study investigated the antiasthma effect of an Ulmus parvifolia bark extract bioprocessed in Lentinus edodes liquid mycelium culture (BPUBE) against allergic asthma in chicken egg ovalbumin (OVA)-sensitized/challenged mice. BPUBE suppressed total IgE release from U266B1 cells in a dose-dependent manner without cytotoxicity. Inhibitory activity of BPUBE against OVA-specific IgE secretion in bronchoalveolar lavage fluid (BALF) was observed in OVA-sensitized/challenged asthmatic mice. BPUBE also inhibited OVA-specific IgG and IgG1 secretion into serum from the allergic mice, suggesting the restoration of a Th2-biased immune reaction to a Th1/Th2-balanced status, as indicated by the Th1/Th2 as well as regulatory T cell (Treg) cytokine profile changes caused by BPUBE in serum or BALF. Inflammatory cell counts in BALF and lung histology showed that leukocytosis and eosinophilia induced by OVA-sensitization/challenge were inhibited by the oral administration of BPUBE. Amelioration of eosinophil infiltration near the trachea was associated with reduced eotaxin and vascular cell adhesion molecule-1 (VCAM-1) levels. Changes in proinflammatory mediator levels in BALF suggest that BPUBE decreased OVA-sensitization-induced elevation of leukotriene C4 (LTC4) and prostaglandin D2 (PGD2). The finding that asthma-associated biomarker levels of OVA-sensitized/challenged mice were much more inhibited with BPUBE treatment than NPUBE (not-bioprocessed Ulmus parvifolia extract) treatment suggested the production of new bioactive compounds by the mushroom mycelia that may be involved in enhancing the observed antiasthmatic properties. The possible relation of the composition determined by proximate analysis and GC/MS to observed bioactivity is discussed. The results suggest that the elm tree (Ulmus parvifolia) bark bioprocessed with mycelia of shiitake (Lentinus edodes

    Full Text Available Background. There is evidence that Tregs are important to prevent allergic diseases like asthma but limited literature exists on role of TH17 cells in allergic diseases. Methods. Fifty children with asthma and respiratory allergy (study group and twenty healthy children (control group were recruited in this study. Total IgE levels and pulmonary function tests were assessed. The expression of Tregs and cytokines was determined by flow cytometry. Results. The average level of total IgE in study group (316.8 ± 189.8 IU/mL was significantly higher than controls (50 ± 17.5 IU/mL, P<0.0001. The frequency of TH17 cells and culture supernatant level of IL-17 in study group (12.09 ± 8.67 pg/mL was significantly higher than control group (2.01 ± 1.27 pg/mL, P<0.001. Alternatively, the frequency of FOXP3 level was significantly lower in study group [(49.00 ± 13.47%] than in control group [(95.91 ± 2.63%] and CD4+CD25+FOXP3+ to CD4+CD25+ ratio was also significantly decreased in study group [(6.33 ± 2.18%] compared to control group [(38.61 ± 11.04%]. The total serum IgE level is negatively correlated with FOXP3 level (r=-0.5273, P<0.0001. The FOXP3 expression is negatively correlated with the IL-17 levels (r=-0.5631, P<0.0001 and IL-4 levels (r=-0.2836, P=0.0460. Conclusions. Imbalance in TH17/Tregs, elevated IL-17, and IL-4 response and downregulation of FOXP3 were associated with allergic asthma.

    The modification of natural flavonoid by glycosylation alters their physicochemical and pharmacokinetic properties, such as increased water solubility and stability, reduced toxicity, and sometimes enhanced or even new pharmacological activities. Kaempferol (KF), a plant flavonoid, and its glycosylated derivative, kaempferol-3-O-rhamnoside (K-3-rh), were evaluated and compared for their anti-inflammatory, anti-oxidant, and anti-asthmatic effects in an asthma model mouse. The results showed that K-3-rh fully maintained its anti-inflammatory and anti-asthmatic effects compared with KF in an asthma model mouse. Both KF and K-3-rh significantly reduced the elevated inflammatory cell numbers in the bronchoalveolar lavage fluid (BALF). KF and K-3-rh also significantly inhibited the increase in Th2 cytokines (IL-4, IL-5, and IL-13) and TNF-α protein levels through inhibition of the phosphorylation Akt and effectively suppressed eosinophilia in a mouse model of allergic asthma. The total immunoglobulin (Ig) E levels in the serum and BALF were also blocked by KF and K-3-rh to similar extents. K-3-rh exerts similar or even slightly higher inhibitory effects on Th2 cytokines and IgE production compared with KF, whereas K-3-rh was less effective at DPPH radical scavenging and the inhibition of ROS generation in inflammatory cells compared with KF. These results suggested that the K-3-rh, as well as KF, may also be a promising candidate for the development of health beneficial foods or therapeutic agents that can prevent or treat allergic asthma.

    Toll-like receptors (TLRs) through innate immune system recognize pathogen associated molecular patterns and play an important role in host defense against bacteria, fungi and viruses. TLR-7 is responsible for sensing single stranded nucleic acids of viruses but its activation has been shown to be protective in mouse models of asthma. The NADPH oxidase (NOX) enzymes family mainly produces reactive oxygen species (ROS) in the lung and is involved in regulation of airway inflammation in response to TLRs activation. However, NOX-4 mediated signaling in response to TLR-7 activation in a mouse model of allergic asthma has not been explored previously. Therefore, this study investigated the role TLR-7 activation and downstream oxidant-antioxidant signaling in a murine model of asthma. Mice were sensitized with ovalbumin (OVA) intraperitoneally and treated with TLR-7 agonist, resiquimod (RSQ) intranasally before each OVA challenge from days 14 to 16. Mice were then assessed for airway reactivity, inflammation, and NOX-4 and nuclear factor E2-related factor 2 (Nrf2) related signaling [inducible nitric oxide synthase (iNOS), nitrotyrosine, lipid peroxides and copper/zinc superoxide dismutase (Cu/Zn SOD)]. Treatment with RSQ reduced allergen induced airway reactivity and inflammation. This was paralleled by a decrease in ROS which was due to induction of Nrf2 and Cu/Zn SOD in RSQ treated group. Inhibition of MyD88 reversed RSQ-mediated protective effects on airway reactivity/inflammation due to reduction in Nrf2 signaling. SOD inhibition produced effects similar to MyD88 inhibition. The current study suggests that TLR-7 agonist is beneficial and may be developed into a therapeutic option in allergic asthma.

    Full Text Available Aeroallergens continue to have a key role in the pathogenesis of asthma and allergic diseases and have recently received increased attention in medical research throughout the world. The prevalence of aeroallergens vary in different regions, depending on the type of climate. The aim of the present study was to determine prevalence of the sensitivity to aeroallergens among patients with asthma and allergic rhinitis (AR, based on skin prick test (SPT reactivity in the province of Bushehr, Iran. In this cross-sectional study, 743 patients were enrolled. The participants had asthma and AR and reacted to at least one allergen with SPT. Skin prick test with standard extracts including house dust mites (HDMs, animal dander, molds and pollens were performed on patients according to the herbal geography of the area. The male to female ratio and mean age of the patients were 1.03 and 27.6± 15.4 year, respectively. Out of 567 patients with AR, the common aeroallergens were HDMs (88.5%, molds (82.9%, animal dander (79.5%, weeds (77.6%, trees (75.5% and grass pollen (71.5%. Moreover, among 176 patients with asthma, the prevalence of aeroallergens were HDMs (90.5 %, molds (80.7%, animal dander (77.5%, weeds (73.3%, trees (73.3% and grass pollen (67.9%. The sensitivity to animal dander, Chenopodium album and Russian thistle pollens were significantly associated with the severity of AR. Moreover, sensitivity to animal dander such as cat and feather of birds, cockroach, Bermuda grass and Chenopodium album pollens were significantly associated with the severity of asthma. The results of this study revealed that HDM was the most common sensitizing aeroallergen in patients with asthma and AR. Molds and animal dander as indoor allergens were also common aeroallergens. We suggest that the hot weather and ambient humidity in the region may be the main cause of the change in the pattern of SPT reactivity.

    Like asthma and atopic dermatitis, allergic rhinitis is an allergic disease, but of the three, it is the only type I allergic disease. Allergic rhinitis includes pollinosis, which is intractable and reduces quality of life (QOL) when it becomes severe. A guideline is needed to understand allergic rhinitis and to use this knowledge to develop a treatment plan. In Japan, the first guideline was prepared after a symposium held by the Japanese Society of Allergology in 1993. The current 6th editi...

    Toll-like receptors (TLR) belong to a large family of pattern recognition receptors known as the ancient 'gatekeepers' of the immune system. TLRs are located at the first line of defense against invading pathogens as well as aeroallergens, making them interesting targets to modulate the natural history of respiratory allergy. Agonists of TLRs have been widely employed in therapeutic or prophylactic preparations useful for asthma/allergic rhinitis (AR) patients. MPL® (a TLR4 agonist) and the CpG oligodeoxynucleotide of 1018 ISS, a TLR9 agonist, show strong immunogenicity effects that make them appropriate adjuvants for allergy vaccines. Targeting the TLRs can enhance the efficacy of specific allergen immunotherapy, currently the only available 'curative' treatment for respiratory allergies. In addition, intranasal administration of AZD8848 (a TLR7 agonist) and VTX-1463 (a TLR8 agonist) as stand-alone therapeutics have revealed efficacy in the relief of the symptoms of AR patients. No anaphylaxis has been so far reported with such compounds targeting TLRs, with the most common adverse effects being transient and local irritation (e.g. redness, swelling and pruritus). Many other compounds that target TLRs have been found to suppress airway inflammation, eosinophilia and airway hyper-responsiveness in various animal models of allergic inflammation. Indeed, in the future a wide variability of TLR agonists and even antagonists that exhibit anti-asthma/AR effects are likely to emerge.

    Asthma is a chronic inflammatory disorder of the airways characterized by airflow obstruction, bronchial hyperreactivity, and underlying inflammation. Two common reasons asthmatics fail standard therapy are incorrect diagnosis and failure to recognize underlying contributing factors. A correct diagnosis of asthma is of great importance to military practitioners since misdiagnosis or uncontrolled asthma affects an individual's operational readiness or determines whether one can receive a medical waiver to enlist in military service. This article presents four cases of patients with dyspnea that have conditions which mimic asthma or complicate asthma management: vocal cord dysfunction misdiagnosed as asthma, respiratory bronchiolitis interstitial lung disease mistaken as asthma, difficult-to-control asthma because of bronchiectasis and allergic bronchopulmonary aspergillosis, and difficult and fatal asthma. Asthma is contrasted to other respiratory disorders, and an outlined approach to asthma diagnosis and management is presented using the Global Initiative for Asthma guidelines.

    Asthma is a chronic inflammatory lung disease in which eosinophils are one of the most important involved cells. These cells accumulate in the lung because of cytokines, which are able to regulate cellular responses. The role of cytokines is well known in allergic asthma: IL4, IL5, IL3, GMCSF are the principally cytokine involved. IL4 regulate IgE synthesis while IL5, (and IL3) cause the activation and accumulation of eosinophils. In non allergic asthma, whilst only IL5 seemed to be important recent data, shows that also IL4 plays an important role. Therefore nowadays no relevant difference seems to exist between allergic and non allergic asthma; instead the primer is different: the allergen in allergic asthma and often an unknown factor in the non allergic asthma. Recently other cytokines have been proved to play a role in the pathogenesis of asthma. IL8 is chemotactic not only for neutrophils but also for eosinophils and might cause chronic inflammation in severe asthma. IL13 works like IL4, while RANTES seems to be a more important chemotactic agent than IL5. Finally IL10, which immunoregulates T lymphocyte responses, may reduce asthma inflammation. In conclusion cytokine made us to learn more about the pathogenesis of asthma even if we do not yet know when and how asthma inflammation develops.

    Objective: To assess the relationship between allergic conjunctivitis(AC) and allergic rhinitis(AR) in pediatric ophthalmology and E.N.T outpatient clinic. Methods:Eight hundred and ninety two patients were enrolled in survey during Mar. 2005~Jan. 2007, 407 allergic conjunctivitis cases were placed in the ophthalmology clinic group and 485 allergic rhinitis cases were from the E.N.T clinic.The comorbid disorders, histories, symptoms, signs of patients were recorded. Type 1 allergy was tested in 479 cases by a specific IgE antibody blood test. Eosinophils were detected in superficial conjunctival scrapings of the superior tarsal conjunctiva and mucosa surface scrapings of middle nasal meatus in 88 cases with both diseases. Results:302(74%), 374(92%), 116(29%) in 407 cases with allergic conjunctivitis had concomitant eczema, rhinitis and asthma, respectively; 334(69%), 430(89%), 145(30%) in 485 cases with allergic rhinitis had concomitant eczema, allergic conjunctivitis and asthma, respectively. The prevalence of allergic conjunctivitis concomitant allergic rhinitis and allergic rhinitis concomitant allergic conjunctivitis had no significant difference(x2=2.6, P>0.05). The prevalence of allergic conjunctivitis and allergic rhinitis concomitant eczema and asthma also had no significant difference (x2=3.08; x2=0.21, P>0.05). The degree of severity of two kinds of disease symptoms is not parallel, in the patients with seasonal allergic conjuctivitis(SAC) and perennial allergic conjunctivitis(PAC), the clinical signs of AR were always severer(x2=258.2, P<0.05)than those of AC. However, the results coincided with the cases with vernal keratoconjuctivitis(VKC)(x2=66.5, P<0.05); Eosinophils were revealed in 50(57%) conjunctival scrapings and nasal mucosa scrapings(x2=1.5, P>0.05), 47(53%) cases had positive results in both scrapings. The main aeroallergens were house dust mites, house dust and fungi, and the main food-allergens were fish, crab and shrimp

    The aim of the study was to investigate the antiasthmatic effects of eugenol (EUG) and the possible mechanisms. Asthma model was established by ovalbumin induction. A total of 50 mice were randomly assigned to five experimental groups: control, OVA, OVA + dexamethasone (2 mg/kg), OVA + EUG (10 mg/kg), and OVA + EUG (20 mg/kg). Airway resistance (Raw) were measured, histological studies were evaluated by the hematoxylin and eosin (HE) staining, interleukin-4 (IL-4) and interleukin-5 (IL-5) were evaluated by enzyme-linked immunosorbent assay (ELISA), Vitamin D3 upregulated protein 1 (VDUP1), IκBα, P-IκBα, NF-κBP65, and p-NF-κBP65 were measured by Western blotting. Our study demonstrated that EUG inhibited OVA-induced increases in Raw and eosinophil count; IL-4 and IL-5 were recovered. Histological studies demonstrated that EUG substantially inhibited OVA-induced eosinophilia in the lung tissue. Western blotting studies demonstrated that EUG substantially inhibited P-IκBα, NF-κBP65, and p-NF-κBP65 protein levels and increased VDUP1 and IκBα protein levels. These findings suggest that EUG may effectively ameliorate the progression of asthma and could be used as a therapy for patients with allergic asthma.

    Asthma is highly prevalent, but current therapies cannot influence the chronic course of the disease. It is thus important to understand underlying early molecular events. In this study, we aimed to use microRNAs (miRNAs) - which are critical regulators of signaling cascades - to identify so far uncharacterized asthma pathogenesis pathways. Therefore, deregulation of miRNAs was assessed in whole lungs from mice with ovalbumin (OVA)-induced allergic airway inflammation (AAI). In silico predicted target genes were confirmed in reporter assays and in house-dust-mite (HDM) induced AAI and primary human bronchial epithelial cells (NHBE) cultured at the air-liquid interface. We identified and validated the transcription factor cAMP-responsive element binding protein (Creb1) and its transcriptional co-activators (Crtc1-3) as targets of miR-17, miR-144, and miR-21. Sec14-like 3 (Sec14l3) - a putative target of Creb1 - was down-regulated in both asthma models and in NHBE cells upon IL13 treatment, while it’s expression correlated with ciliated cell development and decreased along with increasing goblet cell metaplasia. Finally, we propose that Creb1/Crtc1-3 and Sec14l3 could be important for early responses of the bronchial epithelium to Th2-stimuli. This study shows that miRNA profiles can be used to identify novel targets that would be overlooked in mRNA based strategies. PMID:28383034

    Full Text Available OBJECTIVE: To determine the prevalence of symptoms of asthma, rhinitis, and atopic eczema in adolescents (AD; 13-14 years living in seven Brazilian cities, by applying the standardized written questionnaire (WQ of the International Study of Asthma and Allergies in Childhood (ISAAC, and to evaluate the time trend nine years after the last assessment of ISAAC phase 3 (ISP3. METHODS: The ISAAC-WQ was answered by 20,099 AD from the Northern, Northeastern, Southeastern, and Southern Brazilian regions. Values obtained were compared to those observed in ISP3 using nonparametric (chi-squared or Fisher tests, and the ratio of annual increment/decrement was established for each of the centers, according to the symptom assessed. RESULTS: Considering the national data and comparing to values of ISP3, there was a decrease in the mean prevalence of active asthma (18.5% vs. 17.5% and an increase in the frequency of severe asthma (4.5% vs. 4.7% and physician-diagnosed asthma (14.3% vs. 17.6%. An increase in prevalence of rhinitis, rhinoconjunctivitis, and atopic eczema was also observed. CONCLUSIONS: The prevalence of asthma, rhinitis, and atopic eczema in Brazil was variable; higher prevalence values, especially of asthma and eczema, were observed in regions located closer to the Equator.

    Full Text Available BACKGROUND: Non-invasive in vivo imaging strategies are of high demand for longitudinal monitoring of inflammation during disease progression. In this study we present an imaging approach using near infrared fluorescence (NIRF imaging in combination with a polyanionic macromolecular conjugate as a dedicated probe, known to target L- and P-selectin and C3/C5 complement factors. METHODOLOGY/PRINCIPAL FINDINGS: We investigated the suitability of dendritic polyglycerol sulfates (dPGS, conjugated with a hydrophilic version of the indocyanine green label with 6 sulfonate groups (6S-ICG to monitor sites of inflammation using an experimental mouse model of allergic asthma. Accumulation of the NIRF-conjugated dPGS (dPGS-NIRF in the inflamed lungs was analyzed in and ex vivo in comparison with the free NIRF dye using optical imaging. Commercially available smart probes activated by matrix metalloproteinase's (MMP and cathepsins were used as a comparative control. The fluorescence intensity ratio between lung areas of asthmatic and healthy mice was four times higher for the dPGS in comparison to the free dye in vivo at four hrs post intravenous administration. No significant difference in fluorescence intensity between healthy and asthmatic mice was observed 24 hrs post injection for dPGS-NIRF. At this time point ex-vivo scans of asthmatic mice confirmed that the fluorescence within the lungs was reduced to approximately 30% of the intensity observed at 4 hrs post injection. CONCLUSIONS/SIGNIFICANCE: Compared with smart-probes resulting in a high fluorescence level at 24 hrs post injection optical imaging with dPGS-NIRF conjugates is characterized by fast uptake of the probe at inflammatory sites and represents a novel approach to monitor lung inflammation as demonstrated in mice with allergic asthma.

  1. The laminin β1-competing peptide YIGSR induces a hypercontractile, hypoproliferative airway smooth muscle phenotype in an animal model of allergic asthma

    2010-12-01

    Full Text Available Abstract Background Fibroproliferative airway remodelling, including increased airway smooth muscle (ASM mass and contractility, contributes to airway hyperresponsiveness in asthma. In vitro studies have shown that maturation of ASM cells to a (hypercontractile phenotype is dependent on laminin, which can be inhibited by the laminin-competing peptide Tyr-Ile-Gly-Ser-Arg (YIGSR. The role of laminins in ASM remodelling in chronic asthma in vivo, however, has not yet been established. Methods Using an established guinea pig model of allergic asthma, we investigated the effects of topical treatment of the airways with YIGSR on features of airway remodelling induced by repeated allergen challenge, including ASM hyperplasia and hypercontractility, inflammation and fibrosis. Human ASM cells were used to investigate the direct effects of YIGSR on ASM proliferation in vitro. Results Topical administration of YIGSR attenuated allergen-induced ASM hyperplasia and pulmonary expression of the proliferative marker proliferating cell nuclear antigen (PCNA. Treatment with YIGSR also increased both the expression of sm-MHC and ASM contractility in saline- and allergen-challenged animals; this suggests that treatment with the laminin-competing peptide YIGSR mimics rather than inhibits laminin function in vivo. In addition, treatment with YIGSR increased allergen-induced fibrosis and submucosal eosinophilia. Immobilized YIGSR concentration-dependently reduced PDGF-induced proliferation of cultured ASM to a similar extent as laminin-coated culture plates. Notably, the effects of both immobilized YIGSR and laminin were antagonized by soluble YIGSR. Conclusion These results indicate that the laminin-competing peptide YIGSR promotes a contractile, hypoproliferative ASM phenotype in vivo, an effect that appears to be linked to the microenvironment in which the cells are exposed to the peptide.

    The incidence of anaphylaxis is under-reported. Children with asthma are frequently atopic and prone to allergic reactions. Parents and clinicians may attribute wheeze of rapid onset to acute severe asthma, rather than recognising an anaphylactic event. Two cases of fatal anaphylaxis are reported who were initially diagnosed as acute severe asthma, and responded poorly to bronchodilator treatment. Survivors of "acute asphyxic asthma" should be screened for reactions to common allergens that p...

    Like asthma and atopic dermatitis, allergic rhinitis is an allergic disease, but of the three, it is the only type I allergic disease. Allergic rhinitis includes pollinosis, which is intractable and reduces quality of life (QOL) when it becomes severe. A guideline is needed to understand allergic rhinitis and to use this knowledge to develop a treatment plan. In Japan, the first guideline was prepared after a symposium held by the Japanese Society of Allergology in 1993. The current 7th editi...

    Background Cockroaches are an important indoor allergen source causing allergic rhinitis and asthma. The aim of this study was to investigate the cockroach prevalence in mainland of China and the cross-reactivity of IgE between cockroach and house dust mite allergen in Chinese patients.Methods The cockroach sensitization pattern was based on a skin prick test (SPT) obtained from a national multicenter prevalence study, in which 6304 patients from 25 allergy centers across China participated. Factors, including different regions of China, age, gender and the correlations between the American and German cockroaches and house dust mite Der p were investigated. Eighteen out of 1236 clinical sera from south China were selected to perform the cross-inhibition assay between house dust mites and cockroaches.Results Totally 25.7% of patients were SPT positive to the American cockroach (Periplaneta Americana, Per a) and 18.7% SPT positive to the German cockroach (Blattella germanica, Bla g). The prevalence of positive cockroach SPT was higher in southern than in northern China, higher in adults than in children, and higher in males than in females.Patients had relatively low levels of cockroach SPT reactions, mainly class 1 or 2. Of the SPT positive cockroach patients,88% were also SPT positive to house dust mite (Dermatophagoides pteronyssinus, Der p). An IgE cross-inhibition study confirmed that Der P sensitization could cause false positive SPT reactions against cockroach.Conclusions A relatively high prevalence of cockroach sensitivity was found in mainland of China. However, a cross-inhibition study showed that only a small number of patients appear to have Bla g and/or Per a as primary sensitizing source. The importance of cockroaches as a risk factor for sensitization and triggers of allergic symptoms in mainland of China needs to be further investigated.

    The role of early childhood infections and immunisation in the development of allergic diseases remains controversial. To examine these associations, six hundred and twenty infants with first-degree relatives with allergic diseases were recruited into the Melbourne Atopy Cohort Study. Information on risk factors and outcomes was collected by interviewer administered questionnaire and was based on parental report and/or a physician's diagnosis. Risk factors examined included early childhood infections (including gastroenteritis, otitis media and lower respiratory tract infections) and immunisations in the first 2 yr of life. Outcomes were current asthma, allergic rhinitis and eczema at 6 yr of age. Univariate and multivariate regression analysis were used to estimate relative risk (RR) and assess confounding. By 6 yr, 79% of the original cohort remained in the study. Those with at least three episodes of gastroenteritis showed an increased risk (crude RR 2.36, 95%CI 1.41 3.95; adjusted RR 2.03 95%CI 1.50 2.75) for the later development of asthma at age 6. Of the scheduled immunisations, Sabin immunisation in the second year had a reduced risk of asthma at 6 yr (crude RR 0.60, 95%CI 0.37 0.98; adjusted RR 0.63 95%CI 0.39 1.02). Combined diphtheria and tetanus (CDT) immunisation in the first year had an increased risk of asthma at 6 yr (RR 1.76, 95%CI 1.11 2.78; adjusted RR 1.88 95%CI 1.28 2.77). Recurrent gastroenteritis in early childhood is associated with a later risk of asthma. This may reflect a cause and effect relationship, or exposure to common risk factors. In contrast, Sabin immunisation in the second year is associated with a decreased risk of asthma in later childhood. CDT immunisation in the first year may be a risk factor for asthma, but the need for CDT immunisation may also be a marker of increased risk of asthma in later childhood.

    In clinically stable asthma the exhaled NO values (F(E)NO) are generally higher than in control subjects. Therefore, reference values are of limited importance in clinical practice. This is demonstrated in this case report, but it is also shown that NO parameters from non-linear modelling do have a clinical value. A subject with asthma was treated with inhaled corticosteroids for 1 week. The non-linear NO model was used to measure the response to treatment. The NO parameters from subjects with atopic rhinitis and asthma were fed into a computer program to generate theoretical F(E)NO₀.₀₅ values, i.e. target values. There was a dramatic decrease in F(E)NO₀.₀₅ due to treatment, from 82 to 34 ppb, but it remained higher than in healthy controls. This is due to the elevated diffusion rate of NO, unchanged by treatment. When the NO parameters are known, a personal best value of F(E)NO₀.₀₅ (fractional concentration of exhaled NO in the gas phase, 0.05 L/s) can be calculated, which can be the target value when only F(E)NO₀.₀₅ can be monitored. In conclusion, reference values for NO parameters are shown to be clinically useful. It is essential that every patient receives his/her target value of F(E)NO₀.₀₅, when only a single NO measurement is available. In our opinion, this is the reason why there are few successful studies of trying to target the NO value with inhaled corticosteroids.

    Regulatory T cells (Tregs) play an important role by controlling allergic inflammation of airways. Recently, it has been shown that statins have immunomodulatory properties, probably mediated by their effects on Tregs. Therefore, we evaluated the in vivo effect of atorvastatin (ATV) on Tregs and its association with the inflammatory process in a model of allergic asthma. BALB/c mice were sensitized with ovalbumin (OVA) and then challenged with intranasal OVA. ATV (40 mg/kg) was delivered by daily intraperitoneal injection for 7 or 15 days before each OVA challenge. ATV treatment for 7 days increased the frequency of Tregs in mediastinal lymph nodes (MLN) and the interleukin (IL)-10 in lungs. After 15 days of treatment, ATV increased the percentage of glucocorticoid-induced tumor necrosis factor receptor-related protein (GITR+) and programmed cell death protein 1 (PD-1+) Tregs in the lung, without enhancing their suppressive activity, but also increased the percentage of conventional T cells expressing GITR+, PD1+, and OX-40 (tumor necrosis factor receptor superfamily member 4). Although no significant changes were observed in the number of inflammatory cells in the bronchoalveolar lavage (BAL), OVA-specific immunoglobulin E in the serum, and type 2 helper (Th2) cytokines in the lungs, there was a significant decrease of peribronchial inflammation that negatively correlated with the Tregs in MLN and the concentration of IL-10 in the lung. These results suggest that ATV has an immunomodulatory role possibly mediated by their effects on Tregs, which could contribute to the control of inflammation during allergic asthma. Further studies are necessary to elucidate the contribution of Treg to immunomodulatory action of statins in the context of allergic asthma. PMID:28066430

    Oxidant-antioxidant imbalance plays an important role in repeated cycles of airway inflammation observed in asthma. It is when reactive oxygen species (ROS) overwhelm antioxidant defenses that a severe inflammatory state becomes apparent and may impact vasculature. Several studies have shown an association between airway inflammation and cardiovascular complications; however so far none has investigated the link between airway oxidative stress and systemic/vascular oxidative stress in a murine model of asthma. Therefore, this study investigated the contribution of oxidative stress encountered in asthmatic airways in modulation of vascular/systemic oxidant-antioxidant balance. Rats were sensitized intraperitoneally with ovalbumin (OVA) in the presence of aluminum hydroxide followed by several intranasal (i.n.) challenges with OVA. Rats were then assessed for airway and vascular inflammation, oxidative stress (ROS, lipid peroxides) and antioxidants measured as total antioxidant capacity (TAC) and thiol content. Challenge with OVA led to increased airway inflammation and oxidative stress with a concomitant increase in vascular inflammation and oxidative stress. Oxidative stress in the vasculature was significantly inhibited by antioxidant treatment, N-acetyl cysteine; whereas hydrogen peroxide (H2O2) inhalation worsened it. Therefore, our study shows that oxidative airway inflammation is associated with vascular/systemic oxidative stress which might predispose these patients to increased cardiovascular risk.

    Objective To evaluate the clinical efficacy and safety of intralymphatic immunotherapy with standardized Dermatophagoides pteronyssinus allergen vaccine for Dermatophagoides pteronyssinus-induced allergic asthma. Methods 72 patients with Dermatophagoides pteronyssinus -induced allergic asthma were randomly divided into intralymphatic immunotherapy treatment group and control group, 36 cases were enrolled in each group. Patients in control group were prescribed budesonide and salbutamol aerosol while patients in intralymphatic immunotherapy treatment group were prescribed above medications and also received 6 ultrasound-guided intra-superficial lymph node injections by using standardized aluminum-adsorbed Dermatophagoides pteronyssinus allergen vaccine ( Alutard ALK, Denmark) every four weeks. The evaluation of clinical efficacy was based on serum Dermatophagoides pteronyssinus slgE, asthma control test (ACT) , pulmonary function test [FEV1% , FEV1/FVC and PEF% ] , medication score on baseline and after treatment, comparing with control group. Adverse reactions were also recorded. Results 32 cases in treatment group completed the study, 2 cases dropped out due to pregnancy and another 2 cases lost. 32 cases in control group completed the study and 4 cases lost. ACT scores, FEV1% , FEV1/FVC sand PEF % values of patients' in intralymphatic immunotherapy group increased significantly, comparing with that of patients in control group. Medication scores and serum Dermatophagoides pteronyssinus slgE of patients in treatment group decreased significantly, comparing with that of pre-treatment and that of in control group. There was no local and systemic adverse reaction in 192 intralymphatic injections among 32 patients. Conclusions Allergen specific ntralymphatic immunotherapy is not only very effective, but also can remarkably shorten the duration of immunotherapy, reduce the number and dose of injection and decrease adverse reaction.

    In this consensus document we summarize the current knowledge on major asthma, rhinitis, and atopic dermatitis endotypes under the auspices of the PRACTALL collaboration platform. PRACTALL is an initiative of the European Academy of Allergy and Clinical Immunology and the American Academy of Allergy, Asthma & Immunology aiming to harmonize the European and American approaches to best allergy practice and science. Precision medicine is of broad relevance for the management of asthma, rhinitis, and atopic dermatitis in the context of a better selection of treatment responders, risk prediction, and design of disease-modifying strategies. Progress has been made in profiling the type 2 immune response-driven asthma. The endotype driven approach for non-type 2 immune response asthma, rhinitis, and atopic dermatitis is lagging behind. Validation and qualification of biomarkers are needed to facilitate their translation into pathway-specific diagnostic tests. Wide consensus between academia, governmental regulators, and industry for further development and application of precision medicine in management of allergic diseases is of utmost importance. Improved knowledge of disease pathogenesis together with defining validated and qualified biomarkers are key approaches to precision medicine.

    Objective To determine the impact of allergic rhinitis on asthma clinical control and lung function. Methods Sixty-three patients with asthma alone or patients with asthma combined with allergic rhinitis ( 36 males and 27 females, mean age: 48.6 ±16. 1 years ) were divided into asthma group( n =32) and asthma combined with allergic rhinitis ( AR ) group( n =31 ) at Chinese PLA general hospital. The Asthma Control Test ( ACT ) score, the Asthma Control Questionnaire ( ACQ ) score, rescue use of salbutamol agonist and percent predicted FEV, ( FEV, % ), percent predicted PEF ( PEF% ) were evaluated respectively between asthma alone group and asthma combined with AR group. Results The patients in asthma combined with AR group had a significantly( P < 0.05 ) lower ACT score ( 16.3 ±5.6) than those with asthma alone ( 19. 0 ±4. 7 ); whereas the ACQ score ( 2. 1 ± 1. 3 ) in patients with asthma combined with AR was significantly higher than those ( 1.4 ± 1. 1 ) with asthma alone( P <0.05 ). The need for the salbutamol-agonist as a rescue medication 4 ( 0,12 ) in patients with asthma combined with AR was significantly( P <0.05 ) higher than those 0( 0,5 ) with asthma alone. The FEV,% ( 64.7 ±23. 1 )% in patients with asthma combined with AR was significantly( P < 0. 05 ) lower than those ( 77.7 ±21.7 )% with asthma alone, and the PEF% ( 65. 8 ±22. 0 )% in the patients with asthma combined with AR was significantly( P <0.05 ) lower than those (79.4 ±26. 3 )% with asthma alone.

    Hyperpolarized (HP) (3)He magnetic resonance imaging has been recently used to produce high-resolution images of pulmonary ventilation after methacholine (MCh) challenge in mouse models of allergic inflammation. This capability presents an opportunity to gain new insights about these models and to more sensitively evaluate new drug treatments in the pre-clinical setting. In the current study, we present our initial experience using two-dimensional (2D), time-resolved (3)He MRI of MCh challenge-induced airways hyperreactivity (AHR) to compare ovalbumin-sensitized and challenged (N = 8) mice to controls (N = 8). Imaging demonstrated that ovalbumin-sensitized and challenged animals exhibited many large ventilation defects even prior to MCh challenge (four out of eight) compared to no defects in the control animals. Additionally, the ovalbumin-sensitized and challenged animals experienced a greater number of ventilation defects (4.5 +/- 0.4) following MCh infusion than did controls (3.3 +/- 0.6). However, due to variability in MCh delivery that was specific to the small animal MRI environment, the difference in mean defect number was not statistically significant. These findings are reviewed in detail and a comprehensive solution to the variability problem is presented that has greatly enhanced the magnitude and reproducibility of the MCh response. This has permitted us to develop a new imaging protocol consisting of a baseline 3D image, a time-resolved 2D series during MCh challenge, and a post-MCh 3D image that reveals persistent ventilation defects.

    This consensus document summarizes the current knowledge on the potential for precision medicine in food allergy, drug allergy, and anaphylaxis under the auspices of the PRACTALL collaboration platform. PRACTALL is a joint effort of the European Academy of Allergy and Clinical Immunology and the American Academy of Allergy, Asthma and Immunology, which aims to synchronize the European and American approaches to allergy care. Precision medicine is an emerging approach for disease treatment based on disease endotypes, which are phenotypic subclasses associated with specific mechanisms underlying the disease. Although significant progress has been made in defining endotypes for asthma, definitions of endotypes for food and drug allergy or for anaphylaxis lag behind. Progress has been made in discovery of biomarkers to guide a precision medicine approach to treatment of food and drug allergy, but further validation and quantification of these biomarkers are needed to allow their translation into practice in the clinical management of allergic disease.

  9. Epigenetics of asthma.

    Asthma is caused by both heritable and environmental factors. It has become clear that genetic studies do not adequately explain the heritability and susceptibility to asthma. The study of epigenetics, heritable non-coding changes to DNA may help to explain the heritable component of asthma. Additionally, epigenetic modifications can be influenced by the environment, including pollution and cigarette smoking, which are known asthma risk factors. These environmental trigger-induced epigenetic changes may be involved in skewing the immune system towards a Th2 phenotype following in utero exposure and thereby enhancing the risk of asthma. Alternatively, they may directly or indirectly modulate the immune and inflammatory processes in asthmatics via effects on treatment responsiveness. The study of epigenetics may therefore play an important role in our understanding and possible treatment of asthma and other allergic diseases. This article is part of a Special Issue entitled: Biochemistry of Asthma.

    2012-01-01

    Conclusions: : Production of pendrin and periostin is upregulated in allergic rhinitis, chronic rhinosinusitis with nasal polyps, and aspirin-induced asthma. These findings suggest that pendrin can induce mucus production and that periostin can induce tissue fibrosis and remodeling in the nasal mucosa. Therefore, these mediators may be therapeutic target candidates for allergic rhinitis, chronic rhinosinusitis with nasal polyps, and aspirin- induced asthma.

    Full Text Available Climate change is expected to have an impact on various aspects of health, including mucosal areas involved in allergic inflammatory disorders that include asthma, allergic rhinitis, allergic conjunctivitis and anaphylaxis. The evidence that links climate change to the exacerbation and the development of allergic disease is increasing and appears to be linked to changes in pollen seasons (duration, onset and intensity and changes in allergen content of plants and their pollen as it relates to increased sensitization, allergenicity and exacerbations of allergic airway disease. This has significant implications for air quality and for the global food supply.

    Allergic bronchopulmonary aspergillosis (ABPA) develops as the result of a hypersensitivity reaction to fungi of the genus Aspergillus. Clinical and radiological presentation can be atypical, requiring a high degree of suspicion on the part of the physician who treats such patients. We report the cases of two patients with APBA in whom the form of presentation--with few asthma symptoms, images showing lobar atelectasia and hilar adenopathy--led to an initial suspicion of lung cancer.

    The allergic rhinitis is the most common immune disorder with a lifetime prevalence of 24% and one of the most common chronic diseases at all--with tendency to rise. It occurs in childhood and influences the patients' social life, school performance and labour productivity. Furthermore the allergic rhinitis is accompanied by a lot of comorbidities, including conjunctivitis, asthma bronchiale, food allergy, neurodermatitis and sinusitis. For example the risk for asthma is 3.2-fold higher for adults with allergic rhinitis than for healthy people.

    2013-08-01

    Occupational asthma (OA) is the most common of all occupational lung diseases in industrialized countries and its prevalence has been rising steadily. It is estimated that occupational factors account for one out of six cases of adult asthmatic patients causing significant morbidity, disability and costs. Due to its high prevalence and substantial health and socio-economic impacts OA represents a significant public health concern. OA can be divided into allergic and non allergic asthma. Allergic OA is further divided into IgE mediated and non IgE mediated. Baker's asthma (BA), is the leading cause of IgE mediated OA caused by high molecular weight antgens in industrialized countries. Innovations in the baking industry during the last few decades have led to the introduction of new allergens inducing OA. OA is potentially preventable, through early diagnosis and exposure cessation interventions. Thus, clinicians should consider the occupational history in every adult patient presenting with newly diagnosed asthma.

    Asthma is a chronic inflammatory disease of the airways. Asthma and other allergic diseases have increased in prevalence during the last decades in many industrialized countries. Among other hypotheses, the possible role of environmental pollutants has received much public and scientific attention. Some pollutants may modulate the different phases of allergic reactions. Inflammation is a critical feature in the pathogenesis of asthma and therefore, beside allergen avoidance, anti-inflammatory treatment is the first line therapy of asthma. Cysteinyl-leukotrienes are lipid mediators which appear to play a major role in the pathophysiology of asthma. Based on current data, it appears that leukotrience receptor antagonists have bronchodilative and anti-inflammatory effects and may therefore enrich the pharmacotherapeutic spectrum within the therapeutic concept of patient management in asthma. (orig.) [Deutsch] Asthma bronchiale ist eine entzuendliche Erkrankung der Atemwege. Epidemiologische Studien konnten eine deutliche Zunahme der Erkrankung in den letzten zwei Jahrzehnten aufzeigen. In der Entstehung von Allergien und Asthma bronchiale spielen Umwelteinfluesse eine grosse Rolle. Luftschadstoffe scheinen mit verschiedenen Allergie-Parametern bei der Sensibilisierung, Symptombildung und Chronifizierung zu interferieren. Da beim Asthma bronchiale neben der Bronchokonstriktion die Entzuendung der Bronchialschleimhaut eine besondere Rolle spielt, wird heute neben Allergenkarenz und prophylaktischen Massnahmen eine fruehzeitige antientzuendliche Asthmatherapie angestrebt. Cysteinyl-Leukotriene gehoeren zu den wirksamsten Entzuendungsmediatoren beim Asthma bronchiale. Leukotrien-Rezeptorantagonisten scheinen sowohl bronchodilatatorische als auch antientzuendliche Wirkungen zu haben und koennten so innerhalb eines Gesamtkonzeptes von antiallergischer und antiasthmatischer Therapie das pharmakotherapeutische Spektrum bereichern.

    Full Text Available Anupama Kewalramani, Mary E BollingerDepartment of Pediatrics, Division of Pediatric Allergy/Pulmonology, University of Maryland School of Medicine, Baltimore, MD, USAAbstract: Food allergy is a potentially severe immune response to a food or food additive. Although a majority of children will outgrow their food allergies, some may have lifelong issues. Food allergies and other atopic conditions, such as asthma, are increasing in prevalence in Western countries. As such, it is not uncommon to note the co-existence of food allergy and asthma in the same patient. As part of the atopic march, many food allergic patients may develop asthma later in life. Each can adversely affect the other. Food allergic patients with asthma have a higher risk of developing life-threatening food-induced reactions. Although food allergy is not typically an etiology of asthma, an asthmatic patient with food allergy may have higher rates of morbidity and mortality associated with the asthma. Asthma is rarely a manifestation of food allergy alone, but the symptoms can be seen with allergic reactions to foods. There may be evidence to suggest that early childhood environmental factors, such as the mother’s and child’s diets, factor in the development of asthma; however, the evidence continues to be conflicting. All food allergic patients and their families should be counseled on the management of food allergy and the risk of developing co-morbid asthma.Keywords: food allergy, diagnosis, treatment, asthma

    Full Text Available Allergic rhinitis, an immunoglobulin E mediated disease, is the most common chronic allergic childhood disease. The disease is characterized by nasal sneezing, rhinorrhea, palate and eye itchiness, and congestion and it can significantly impact children’s health. It causes uncomfortable symptoms, impairs quality of life and can predispose to the development of comorbidities such as asthma. Etiological diagnosis is based on cutaneous prick tests, which have a high sensitivity and specificity rate and which can be easily applied to young children. Treatment initially involves avoidance measures and, when necessary, pharmacotherapy or immunotherapy. Pharmacotherapy generally involves antihistamines and/or nasal corticosteroids, but leukotriene antagonists have also demonstrated effectiveness in treating allergic rhinitis symptoms. In this article, the symptoms, diagnosis and treatment of allergic rhinitis in childhood are discussed. (Journal of Current Pediatrics 2010; 8: 105-12

  13. Allergen challenge induces Ifng dependent GTPases in the lungs as part of a Th1 transcriptome response in a murine model of allergic asthma.

    Directory of Open Access Journals (Sweden)

    Nilesh Dharajiya

    Full Text Available According to the current paradigm, allergic airway inflammation is mediated by Th2 cytokines and pro-inflammatory chemokines. Since allergic inflammation is self-limited, we hypothesized that allergen challenge simultaneously induces anti-inflammatory genes to counter-balance the effects of Th2 cytokines and chemokines. To identify these putative anti-inflammatory genes, we compared the gene expression profile in the lungs of ragweed-sensitized mice four hours after challenge with either PBS or ragweed extract (RWE using a micro-array platform. Consistent with our hypothesis, RWE challenge concurrently upregulated Th1-associated early target genes of the Il12/Stat4 pathway, such as p47 and p65 GTPases (Iigp, Tgtp and Gbp1, Socs1, Cxcl9, Cxcl10 and Gadd45g with the Th2 genes Il4, Il5, Ccl2 and Ccl7. These Th1-associated genes remain upregulated longer than the Th2 genes. Augmentation of the local Th1 milieu by administration of Il12 or CpG prior to RWE challenge further upregulated these Th1 genes. Abolition of the Th1 response by disrupting the Ifng gene increased allergic airway inflammation and abrogated RWE challenge-induced upregulation of GTPases, Cxcl9, Cxcl10 and Socs1, but not Gadd45g. Our data demonstrate that allergen challenge induces two sets of Th1-associated genes in the lungs: 1 Ifng-dependent genes such as p47 and p65 GTPases, Socs1, Cxcl9 and Cxcl10 and 2 Ifng-independent Th1-inducing genes like Gadd45g. We propose that allergen-induced airway inflammation is regulated by simultaneous upregulation of Th1 and Th2 genes, and that persistent unopposed upregulation of Th1 genes resolves allergic inflammation.

    Full Text Available Adult bronchial asthma (hereinafter, asthma is characterized by chronic airway inflammation, reversible airway narrowing, and airway hyperresponsiveness. Long-standing asthma induces airway remodeling to cause intractable asthma. The number of patients with asthma has increased, and that of patients who die from asthma has decreased (1.5 per 100,000 patients in 2012. The aim of asthma treatment is to enable patients with asthma to lead a normal life without any symptoms. A good relationship between physicians and patients is indispensable for appropriate treatment. Long-term management with antiasthmatic agents and elimination of the causes and risk factors of asthma are fundamental to its treatment. Four steps in pharmacotherapy differentiate between mild and intensive treatments; each step includes an appropriate daily dose of an inhaled corticosteroid, varying from low to high. Long-acting 02-agonists, leukotriene receptor antagonists, and sustained-release theophylline are recommended as concomitant drugs, while anti-immunoglobulin E antibody therapy has been recently developed for the most severe and persistent asthma involving allergic reactions. Inhaled 02-agonists, aminophylline, corticosteroids, adrenaline, oxygen therapy, and others are used as needed in acute exacerbations by choosing treatment steps for asthma exacerbations depending on the severity of attacks. Allergic rhinitis, chronic obstructive pulmonary disease, aspirin-induced asthma, pregnancy, asthma in athletes, and coughvariant asthma are also important issues that need to be considered.

    Objective In recent years WAO advocated combined allergic rhinitis and asthma syndrome (CARAS),a new diagnostic term. Meanwhile, both upper and lower respiratory tract need united diagnosis and treatment. So CARAS patients were treated through inhalation of glucocorticoid using spacer for nose and mouth, thus to evaluate the value of inhaled glucocorticoid through nose in treatment of CARAS.Methods Eighty-six CARAS patients treated by inhaling budesonide through nose-mouth spacer were randomly assigned to mouth-inhaled group and nose-inhaled group. The score for nosal symptoms, chest symptoms,lung function and airway responsiveness were observed before and after treatment. Results Both nose-inhaled group and mouth-inhaled group improved the chest symptoms and pulmonary ventilation function and reduce airway hyperreactivity, showing significant difference after treatment( P<0.01). There was no significant difference between two groups after treatment ( P>0.05). But the nose-inhaled group was superior to the mouth-inhaled group in nosal symptoms improvement( P<0.01). Conclusions Compared with the oral inhalation, nasal inhalation of budesonide could not only control allergic rhinitis, but also prevent asthma,which should be recommended to apply in the prevention and treatment of CARAS patients.%目的 最近世界变态反应组织(WAO)提出了过敏性鼻炎-哮喘综合征(combined allergic rhinitis and asthma syndrome,CARAS)这一新的诊断术语.同时指出上、下呼吸道疾病需要进行联合诊断和联合治疗.采用了鼻-口两用雾化器(spacer),分别经口或经鼻吸入糖皮质激素治疗CARAS患者,以评价经鼻吸入糖皮质激素在防治CARAS的价值.方法 采用鼻-口两用雾化器(商品名:吸保)吸入布地奈德气雾剂治疗86例CARAS患者,随机将患者分为经口吸入组和经鼻吸入组,同时观察了两组治疗前后的鼻部症状记分、胸部症状记分、肺功能和气道反应性.结果 鼻吸组

    CD4(+)Foxp3(+)T cells (Tregs) mediate homeostatic peripheral tolerance by suppressing helper T2 cells in allergy. However, the regulation of asthmatic inflammation by local (in situ) Tregs in asthma remains unclear. BALB/c mice sensitized and challenged with ovalbumin (OVA) (asthma group) developed asthmatic inflammation with eosinophils and lymphocytes, but not mast cells. The number of Tregs in the circulation, pulmonary lymph nodes (pLNs), and thymi significantly decreased in the asthma group compared to the control group without OVA sensitization and challenge in the effector phase. The development of asthmatic inflammation is inversely related to decreased Tregs with reduced mRNA expression such as interleukin (IL)-4, transforming growth factor-β1, and IL-10, but not interferon-γ, in pLNs. Moreover, M2 macrophages increased in the local site. The present study suggests that Tregs, at least in part, may regulate the development of asthmatic inflammation by cell-cell contact and regional cytokine productions.

    2013-10-01

    There is mounting evidence that obesity is associated with asthma, both of which are seeing a dramatic increase in prevalence. Not only is obesity a risk factor for the development of asthma but it is also associated with poor asthma control. Asthma phenotypes associated with obesity include early-onset allergic asthma and late-onset non-allergic asthma. The pathogenesis of the linkage is complex; obesity causes a variety of mechanical, metabolic, and immunological changes that can affect the airways. The treatment of asthma in obesity can be challenging, as obesity is associated with poor response to standard controller medications. A tailored approach that involves combining pharmacologic and non-pharmacologic therapies including weight loss, dietary interventions, and exercise, along with identification and treatment of obstructive sleep apnea, should therefore be considered in this population.

    The simultaneous increment in the prevalence of obesity and allergic diseases suggests a possible link between them. This review focuses on the consequences of obesity on allergic diseases, especially asthma in children and adolescents, and evaluates the available evidence on the possible mechanisms. Obesity is related more strongly to nonatopic than atopic asthma, suggesting non-eosinophilic inflammation and Th1 polarization. Among other allergic diseases, the association is more consistent with eczema compared to allergic rhinitis/rhinoconjunctivitis. The mechanisms of asthma in obese individuals could involve mechanical effects of obesity on lung function, adipokines-mediated inflammation, shared factors (diet, genetics, sedentary lifestyle) and comorbidities.

    Full Text Available Breastfeeding has been linked to a reduction in the prevalence of allergy and asthma. However, studies on this relationship vary in outcome, which may partly be related to differences in breast milk composition. In particular breast milk composition may differ between allergic and non-allergic mothers. Important components that may be involved are breast milk proteins, as these are known to regulate immune development in the newborn. The objective of this study was therefore to explore differences in the proteins of breast milk from 20 allergic and non-allergic mothers. The results from this comparison may then be used to generate hypotheses on proteins associated with allergy in their offspring.Milk samples from allergic and non-allergic mothers were obtained from the PIAMA project, a prospective birth cohort study on incidence, risk factors, and prevention of asthma and inhalant allergy. Non-targeted proteomics technology, based on liquid chromatography and mass spectrometry, was used to compare breast milk from allergic and non-allergic mothers.Nineteen proteins, out of a total of 364 proteins identified in both groups, differed significantly in concentration between the breast milk of allergic and non-allergic mothers. Protease inhibitors and apolipoproteins were present in much higher concentrations in breast milk of allergic than non-allergic mothers. These proteins have been suggested to be linked to allergy and asthma.The non-targeted milk proteomic analysis employed has provided new targets for future studies on the relation between breast milk composition and allergy.

    Full Text Available Increase in the asthma prevalence in many countries over the recent decades, highlights the need for a greater understanding of the risk factors for asthma. Be-cause asthma is the result of interaction between genetic and environmental fac-tors, increasing prevalence is certainly the result of changes in environmental fac-tors because of process of wesernization. That is the reason for higher prevalence in countries where a traditional to a westernized lifestyle occurred earlier. This increasing prevalence has affected both rural and urban communities, suggesting that local environmental factors such as exposure to allergens or industrial air pol-lutions are not the sole cause. In the last few years, nutrition has represented an important conditioning factor of many cardiovascular, gastrointestinal and chronic pulmonary diseases. So it has been hypothesized that dietary constituents influence the immune system and thus, may also be actively involved in the onset of asthma and other allergic diseases. Dietary constituents can play beneficial as well as det-rimental role in asthma. The possible role of diet in the development of asthma can be described as follows: first, a food allergen can cause asthma. Second, there is role of breast-feeding for prevention of asthma later in life. Third, a low intake of antioxidative dietary constituents might be a risk factor for asthma. Moreover, role of cations such as sodium, potassium and magnesium has been described in development of asthma. Finally, intake of fatty acids specially the role of omega-3 and omega-6 fatty acids play important role in cause of asthma.

  11. Lung-homing of endothelial progenitor cells and airway vascularization is only partially dependant on eosinophils in a house dust mite-exposed mouse model of allergic asthma.

    Directory of Open Access Journals (Sweden)

    Nirooya Sivapalan

    Full Text Available Asthmatic responses involve a systemic component where activation of the bone marrow leads to mobilization and lung-homing of progenitor cells. This traffic may be driven by stromal cell derived factor-1 (SDF-1, a potent progenitor chemoattractant. We have previously shown that airway angiogenesis, an early remodeling event, can be inhibited by preventing the migration of endothelial progenitor cells (EPC to the lungs. Given intranasally, AMD3100, a CXCR4 antagonist that inhibits SDF-1 mediated effects, attenuated allergen-induced lung-homing of EPC, vascularization of pulmonary tissue, airway eosinophilia and development of airway hyperresponsiveness. Since SDF-1 is also an eosinophil chemoattractant, we investigated, using a transgenic eosinophil deficient mouse strain (PHIL whether EPC lung accumulation and lung vascularization in allergic airway responses is dependent on eosinophilic inflammation.Wild-type (WT BALB/c and eosinophil deficient (PHIL mice were sensitized to house dust mite (HDM using a chronic exposure protocol and treated with AMD3100 to modulate SDF-1 stimulated progenitor traffic. Following HDM challenge, lung-extracted EPCs were enumerated along with airway inflammation, microvessel density (MVD and airway methacholine responsiveness (AHR.Following Ag sensitization, both WT and PHIL mice exhibited HDM-induced increase in airway inflammation, EPC lung-accumulation, lung angiogenesis and AHR. Treatment with AMD3100 significantly attenuated outcome measures in both groups of mice. Significantly lower levels of EPC and a trend for lower vascularization were detected in PHIL versus WT mice.This study shows that while allergen-induced lung-homing of endothelial progenitor cells, increased tissue vascularization and development lung dysfunction can occur in the absence of eosinophils, the presence of these cells worsens the pathology of the allergic response.

    Andrographolide from traditional Chinese herbal medicines previously showed it possesses a strong anti-inflammatory activity. In present study, we investigated whether Andrographolide could inhibit allergen-induced airway inflammation and airways hyper-responsiveness and explored the mechanism of Andrographolide on allergen-induced airway inflammation and airways hyper-responsiveness. After sensitized and challenged by ovalbumin, the BALB/c mice were administered intraperitoneally with Andrographolide. Hyper-responsiveness was recorded. The lung tissues were assessed by histological examinations. NF-κB in lung was determined by immunofluorescence staining and Western blotting. Treatment of mice with Androqrapholide displayed lower Penh in response to asthma group mice. After treatment with Andrographolide, the extent of inflammation and cellular infltrafion in the airway were reduced. Andrographolide interrupted NF-κB to express in cell nucleus. The level of NF-κB expression was inhibited by Andrographolide. The data indicate that Andrographolide from traditional Chinese herbal medicines could inhibit extensive infiltration of inflammatory cells in lung and decrease airway hyperreactivity. Andrographolide could inhibit NF-κB expression in lung and suppress NF-κB expressed in the nucleus of airway epithelial cells. Cellular & Molecular Immunology. 2009;6(5):381-385.

    Oxidants are generated in asthmatic airways due to infiltration of inflammatory leukocytes and resident cells in the lung. Reactive oxygen species (ROS) such as hydrogen peroxide and superoxide radical may leak into systemic circulation when generated in uncontrolled manner and may impact vasculature. Our previous studies have shown an association between airway inflammation and systemic inflammation; however so far none has investigated the impact of airway oxidative inflammation on hepatic oxidative stress and Th1/Th2/Th17 cytokine markers in liver/vasculature in a murine model of asthma. Therefore, this study investigated the contribution of oxidative stress encountered in asthmatic airways in modulation of systemic/hepatic Th1/Th2/Th17 cytokines balance and hepatic oxidative stress. Mice were sensitized intraperitoneally with cockroach extract (CE) in the presence of aluminum hydroxide followed by several intranasal (i.n.) challenges with CE. Mice were then assessed for systemic/hepatic inflammation through assessment of Th1/Th2/Th17 cytokines and oxidative stress (iNOS, protein nitrotyrosine, lipid peroxides and myeloperoxidase activity). Challenge with CE led to increased Th2/Th17 cytokines in blood/liver and hepatic oxidative stress. However, only Th17 related pro-inflammatory markers were upregulated by hydrogen peroxide (H2O2) inhalation in vasculature and liver, whereas antioxidant treatment, N-acetyl cysteine (NAC) downregulated them. Hepatic oxidative stress was also upregulated by H2O2 inhalation, whereas NAC attenuated it. Therefore, our study shows that airway oxidative inflammation may contribute to systemic inflammation through upregulation of Th17 immune responses in blood/liver and hepatic oxidative stress. This might predispose these patients to increased risk for the development of cardiovascular disorders.

    Evidence shows that psychosocial stress exacerbates asthma, but there is little intervention to alleviate negative effects of psychosocial stress on asthma. We investigated the role of icariin in anti-inflammation and anti-anxiety potential in a murine model combined psychosocial stress with allergic exposure. The results indicated that icariin administered remarkable increased activity in the center of the open field, reversed airway hyperresponsivenesss, reduced inflammatory cytokine infiltration to the lung and whole body and also in part recovered glucocorticoid responsiveness. Furthermore, our data also showed that icariin significantly inhibited increases of corticosterone and markedly increased glucocorticoid receptor mRNA and protein expression in the lungs of mice exposed to both stress and allergen. Collectively, we speculate that inducing glucocorticoid receptor modulation might be the potential mechanisms of icariin to facilitate corticosteroid responsiveness of cytokine production.

    The application of recently developed sensitive, specific, culture-independent tools for identification of microbes is transforming concepts of microbial ecology, including concepts of the relationships between the vast complex populations of microbes associated with ourselves and with states of health and disease. Although most work initially focused on the community of microbes (microbiome) in the gastrointestinal tract and its relationship to gastrointestinal disease, interest has expanded to include study of the relationships of the airway microbiome to asthma and its phenotypes and to the relationships between the gastrointestinal microbiome, development of immune function, and predisposition to allergic sensitization and asthma. Here we provide our perspective on the findings of studies of differences in the airway microbiome between asthmatic patients and healthy subjects and of studies of relationships between environmental microbiota, gut microbiota, immune function, and asthma development. In addition, we provide our perspective on how these findings suggest the broad outline of a rationale for approaches involving directed manipulation of the gut and airway microbiome for the treatment and prevention of allergic asthma.

    2003-06-01

    Respiratory infections can cause wheezing illnesses in children of all ages and also can influence the causation and disease activity of asthma. For years it has been recognized that respiratory syncytial virus infections often produce the first episode of wheezing in children who go on to develop chronic asthma. More recently, it has been proposed that repeated infections with other common childhood viral pathogens might help the immune system develop in such a way as to prevent the onset of allergic diseases and possibly asthma. In addition to the effects of viral infections, infections with certain intracellular pathogens, such as chlamydia and mycoplasma, may cause acute and chronic wheezing in some individuals, whereas common cold and acute sinus infections can trigger acute symptoms of asthma. In this article, the epidemiologic, mechanistic, and treatment implications of the association between respiratory infections and asthma are discussed.

  13. Occupational Respiratory Allergic Diseases in Healthcare Workers.

    Science.gov (United States)

    Mazurek, Jacek M; Weissman, David N

    2016-11-01

    Healthcare workers (HCWs) are exposed to a range of high and low molecular weight agents that are allergic sensitizers or irritants including cleaners and disinfectants, natural rubber latex, and various medications. Studies have shown that exposed HCWs are at risk for work-related rhinitis and asthma (WRA). Work-related rhinitis may precede development of WRA and should be considered as an early marker of WRA. Avoidance of causative exposures through control strategies such as elimination, substitution, engineering controls, and process modification is the preferred primary prevention strategy for preventing development of work-related allergic diseases. There is limited evidence for the effectiveness of respirators in preventing occupational asthma. If sensitizer-induced WRA is diagnosed, it is important to avoid further exposure to the causative agent, preferably by more rigorous application of exposure control strategies to the workplace. This review focuses on allergic occupational respiratory diseases in HCWs.

    Sideleva, O; Dixon, A E

    2014-03-01

    Obesity is a major risk factor for the development of asthma, and causes severe, uncontrolled disease that responds poorly to therapy. The obese state alters early onset allergic asthma, and leads to the development of a novel form of late onset asthma secondary to obesity. The presentation of early onset allergic asthma is altered through effects on immune function. Factors such as mechanical loading, effects of adipokines on airways, altered diet, insulin resistance and altered metabolism of nitric oxide likely all contribute to increased airway reactivity in obesity, causing late onset asthma in obesity. Obesity also alters responses to environmental factors such as ozone and particulate matter. Focused studies to understand the importance of these factors in the pathogenesis of airway disease in obesity will be essential to develop therapies to intervene in this new epidemic of airway disease.

    [Objective] To investigate the effect of Trichinella spiralis infection on allergic asthma, through the study of the change of total IgE levels in surum and bronchoalveolar lavage fluid (BALF) when the mice which were infected with Trichinella spiralis were suffering from allergic asthma. [Methods] Female BALB/c mice were randomly divided into three groups (six mice each), including A as control group, B as allergic asthma group, C as asthma followed by Trichinella spiralis infection. The animals in group C were intragastrically infected with 200-300 Trichinella spiralis muscle larvae. Four weeks later, ovalbumin (OVA) was used to induce allergic asthma for mice in group B and C, in order to establish experimental animal model. After eight weeks, all mice were killed and total IgE levels were measured in serum and BALF.[ Results] Total IgE levels were measured by ELISA. Total IgE levels from serum in group A, B and C were (61.79 ± 25.79) , (437.08 ± 75.68) , (251.64 ± 107.27) ng/ml. Total IgE level in group C was lower than that in group B (P< 0.05). BALF total IgE levels in group A, B and C were (43.70 ± 29.49), (387.49 ± 148.32), (102.50 ± 49.55) ng/ml. Total IgE level in group C was lower than that in group B (P < 0.05). [Conclusion] Trichinella spiralis infection can inhibit the total IgE level of mice with the allergic asthma.%通过研究旋毛虫感染小鼠在过敏性哮喘发病时血清及肺泡灌洗液中总IgE水平变化,探讨旋毛虫感染对过敏性哮喘的影响.[方法]取雌性、8周龄BALB/c小鼠,随机分为3组,A组为空白对照组,B组为单纯过敏性哮喘组,C组为感染旋毛虫后哮喘组.C组经灌胃感染旋毛虫囊包幼虫200 ~ 300条;4周后,以卵清白蛋白(ovalbumin,OVA)分别对B组和C组小鼠进行致敏激发,建立过敏性哮喘模型;8周后,取小鼠血清、肺泡灌洗液,检测总IgE水平.[结果]ELISA法检测血清中A、B、C组小鼠总IgE水平分别为(61.79±25.79)、(437.08±75.68)

  11. Prenatal Stress, Prematurity, and Asthma.

    2015-12-01

    Asthma is the most common chronic disease of childhood, affecting millions of children in the United States and worldwide. Prematurity is a risk factor for asthma, and certain ethnic or racial minorities such as Puerto Ricans and non-Hispanic blacks are disproportionately affected by both prematurity and asthma. In this review, we examine current evidence to support maternal psychosocial stress as a putative link between prematurity and asthma, while also focusing on disruption of the hypothalamic-pituitary-adrenal (HPA) axis and immune responses as potential underlying mechanisms for stress-induced "premature asthma." Prenatal stress may cause not only abnormalities in the HPA axis but also epigenetic changes in the fetal glucocorticoid receptor gene (NR3C1), leading to impaired glucocorticoid metabolism. Moreover, maternal stress can alter fetal cytokine balance, favoring TH2 (allergic) immune responses characteristic of atopic asthma: interleukin 6 (IL-6), which has been associated with premature labor, can promote TH2 responses by stimulating production of IL-4 and IL-13. Given a link among stress, prematurity, and asthma, future research should include birth cohorts aimed at confirming and better characterizing "premature asthma." If confirmed, clinical trials of prenatal maternal stress reduction would be warranted to reduce the burden of these common comorbidities. While awaiting the results of such studies, sound policies to prevent domestic and community violence (eg, from firearms) are justified, not only by public safety but also by growing evidence of detrimental effects of violence-induced stress on psychiatric and somatic health.

  12. Perimenstrual asthma: from pathophysiology to treatment strategies.

    Graziottin, Alessandra; Serafini, Audrey

    2016-01-01

    The prevalence of asthma is about 9,7 % in women and 5,5 % in men. Asthma can deteriorate during the perimenstrual period, a phenomenon known as perimenstrual asthma (PMA), which represents a unique, highly symptomatic asthma phenotype. It is distinguished from traditional allergic asthma by aspirin sensitivity, less atopy, and lower lung capacity. PMA incidence is reported to vary between 19 and 40 % of asthmatic women. The presence of PMA has been related to increases in asthma-related emergency department visits, hospitalizations and emergency treatment including intubations. It is hypothesized that hormonal status may influence asthma in women, focusing on the role of sex hormones, and specifically on the impact of estrogens' fluctuations at ovulation and before periods. This paper will focus on the pathophysiology of hormone triggered cycle related inflammatory/allergic events and their relation with asthma. We reviewed the scientific literature on Pubmed database for studies on PMA. Key word were PMA, mastcells, estrogens, inflammation, oral contraception, hormonal replacement therapy (HRT), and hormone free interval (HFI). Special attention will be devoted to the possibility of reducing the perimenstrual worsening of asthma and associated symptoms by reducing estrogens fluctuations, with appropriate hormonal contraception and reduced HFI. This novel therapeutical approach will be finally discussed.

  13. Treatment of allergic rhinitis during pregnancy.

    Allergic rhinitis is a frequent problem during pregnancy. In addition, physiological changes associated with pregnancy can affect the upper airways. Evidence-based guidelines on the management of allergic rhinitis have recently been published, the most recent being the Allergic Rhinitis and its Impact on Asthma (ARIA)--World Health Organization consensus. Many pregnant women experience allergic rhinitis and particular attention is required when prescribing drugs to these patients. Medication can be prescribed during pregnancy when the apparent benefit of the drug is greater than the apparent risk. Usually, there is at least one drug from each major class that can be safely utilised to control symptoms. All glucocorticosteroids are teratogenic in animals but, when the indication is clear (for diseases possibly associated, such as severe asthma exacerbation), the benefit of the drug is far greater than the risk. Inhaled glucocorticosteroids (e.g. beclomethasone or budesonide) have not been incriminated as teratogens in humans and are used by pregnant women who have asthma. A few histamine H(1)-receptor antagonists (H(1)-antihistamines) can safely be used as well. Most oral decongestants (except pseudoephedrine) are teratogenic in animals. There are no such data available for intra-nasal decongestants. Finally, pregnancy is not considered as a contraindication for the continuation of allergen specific immunotherapy.

    Highlights: Black-Right-Pointing-Pointer Silibinin diminishes ovalbumin-induced inflammatory reactions in the mouse lung. Black-Right-Pointing-Pointer Silibinin reduces the levels of various cytokines into the lung of allergic mice. Black-Right-Pointing-Pointer Silibinin prevents the development of airway hyperresponsiveness in allergic mice. Black-Right-Pointing-Pointer Silibinin suppresses NF-{kappa}B transcriptional activity. -- Abstract: Allergic asthma is a chronic inflammatory disease regulated by coordination of T-helper2 (Th2) type cytokines and inflammatory signal molecules. Silibinin is one of the main flavonoids produced by milk thistle, which is reported to inhibit the inflammatory response by suppressing the nuclear factor-kappa B (NF-{kappa}B) pathway. Because NF-{kappa}B activation plays a pivotal role in the pathogenesis of allergic inflammation, we have investigated the effect of silibinin on a mouse ovalbumin (OVA)-induced asthma model. Airway hyperresponsiveness, cytokines levels, and eosinophilic infiltration were analyzed in bronchoalveolar lavage fluid and lung tissue. Pretreatment of silibinin significantly inhibited airway inflammatory cell recruitment and peribronchiolar inflammation and reduced the production of various cytokines in bronchoalveolar fluid. In addition, silibinin prevented the development of airway hyperresponsiveness and attenuated the OVA challenge-induced NF-{kappa}B activation. These findings indicate that silibinin protects against OVA-induced airway inflammation, at least in part via downregulation of NF-{kappa}B activity. Our data support the utility of silibinin as a potential medicine for the treatment of asthma.

    We report a male with history of recurrent infections (recurrent oral aphtous disease [ROAD], middle ear infections and pharyngo amigdalitis) every 3 weeks since he was 7 months old. At the age of 3 years cyclic neutropenia was diagnosed with cyclic fall in the total neutrophil count in blood smear every 21 days and prophylactic antimicrobial therapy was indicated. Episodic events every 3 weeks of acute asthma and allergic rhinitis were detected at the age of 6 years old and specific immunotherapy to Bermuda grass was given during 3 years with markedly improvement in his allergic condition but not in the ROAD. He came back until the age of 16 with episodic acute asthma and ROAD. The total neutrophil count failed to 0 every 21 days and surprisingly the total eosinophil count increased up to 2,000 at the same time, with elevation of serum IgE (412 Ul/mL). Specific immunotherapy to D.pt. and Aller.a. and therapy with timomodulin was indicated. After 3 months we observed clinical improvement in the asthmatic condition and the ROAD disappeared, but the total neutrophil count did not improve. We present this case as a rare association between 2 diseases with probably no etiological relationship but may be physiopatological that could help to understand more the pathogenesis of asthma.

  17. Reducing allergic symptoms through eliminating subgingival plaque

    2008-12-01

    Full Text Available Background: Elimination of subgingival plaque for prevention and treatment of periodontal diseases through scaling is a routine procedure. It is also well-known that periodontal disease is related to systemic diseases. Nevertheless, the idea how scaling procedures also able to reduce allergic symptoms i.e. eczema and asthma, is not easily accepted, because it is contradictory to the “hygiene hypothesis”. However, since allergic symptoms also depend on variable factors such as genetic, environmental and infection factors; every possible effort to eliminate or avoid from these factors had to be considered. Subgingival plaque is a source of infection, especially the Gram-negative bacteria that produced endotoxin (lipopolysaccharides, LPS, a potential stimulator of immunocompetent cells, which may also related to allergy, such as mast cells and basophils. In addition, it also triggers the “neurogenic switching” mechanism which may be initiated from chronic gingivitis. Objective: This case report may explain the possible connection between subgingival plaque and allergy based on evidence-based cases. Case: Two adult siblings who suffered from chronic gingivitis also showed different manifestations of allergy that were allergic dermatitis and asthma for years. They were also undergone unsuccessful medical treatment for years. Oral and topical corticosteroids were taken for dermatitis and inhalation for asthma. Case Management: Patients were conducted deep scaling procedures, allergic symptoms gradually diminished in days even though without usual medications. Conclusion: Concerning to the effectiveness of scaling procedures which concomitantly eliminate subgingival plaque in allergic patients, it concluded that this concept is logical. Nevertheless, further verification and collaborated study with allergic expert should be done.

Obesity is a major risk factor for new-onset asthma. This article will discuss the role of mechanical and metabolic factors, as well as obesity-related comorbidities, in both causing airway disease and also affecting response to therapy in obese asthmatics. Asthma in obese individuals probably includes a spectrum of disease with at least two distinct phenotypes: early-onset allergic disease complicated by obesity and late-onset disease developing in the setting of obesity. Both phenotypes are distinct from asthma in lean individuals. Treatment of asthma in obesity needs to consider altered response to controller therapy, and the fact that mechanical factors, metabolic inflammation and other comorbidities are probably contributing to airway disease. Future studies should focus on the development of therapies specifically tailored towards the treatment of asthma in obesity.

    Early identification of children at risk of developing asthma at school age is crucial, but the usefulness of childhood asthma prediction models in clinical practice is still unclear. We systematically reviewed all existing prediction models to identify preschool children with asthma-like symptoms at risk of developing asthma at school age. Studies were included if they developed a new prediction model or updated an existing model in children aged 4 years or younger with asthma-like symptoms, with assessment of asthma done between 6 and 12 years of age. 12 prediction models were identified in four types of cohorts of preschool children: those with health-care visits, those with parent-reported symptoms, those at high risk of asthma, or children in the general population. Four basic models included non-invasive, easy-to-obtain predictors only, notably family history, allergic disease comorbidities or precursors of asthma, and severity of early symptoms. Eight extended models included additional clinical tests, mostly specific IgE determination. Some models could better predict asthma development and other models could better rule out asthma development, but the predictive performance of no single model stood out in both aspects simultaneously. This finding suggests that there is a large proportion of preschool children with wheeze for which prediction of asthma development is difficult.

    Every time they exist more demonstrations of the paper than performs the line monocytes-macrophage in the patogenesis of the bronchial asthma. The mononuclear phagocytes cells, as the alveolar macrophages, also they can be activated during allergic methods. The monocytes macrophages are possible efficient inductors of the inflammation; this due to the fact that they can secrete inflammatory mediators, between those which are counted the pre-forming granules of peptides, metabolites of oxidation activation, activator of platelets activator and metabolites of the arachidonic acid. The identification of IL-1 in the liquidate of the bronchial ablution of sick asthmatic, as well as the identification of IL-1 in the I bronchioalveolar washing of places of allergens cutaneous prick, supports the activation concept mononuclear of phagocytic cells in allergic sufferings.

    Full Text Available The worldwide prevalence, morbidity, and mortality of asthma have dramatically increased over the last few decades and there is a clear need to identify new, effective, therapeutic and prophylactic strategies. Despite high numbers of NK cells in the lung and their ability to and generate a variety of immunomodulatory mediators the potential of these cells as therapeutic targets in allergic airway disease has been largely overlooked. The fact that IgE, acting through FcγRIII can activate NK cells resulting in cytokine/chemokine production implies that NK cells may contribute to IgE-mediated allergic responses. Indeed, current evidence suggests that NK cells can promote allergic airway responses during sensitization and ongoing inflammation. In animals models increased NK cells are observed in the lung following antigen challenge, while depletion of NK cells before immunization inhibits allergic airway inflammation. Moreover, in asthmatics NK cell phenotype is altered, and may contribute to promotion of the pro-inflammatory Th2-type environment. Conversely, driving NK cells towards an IFN-γ-secreting phenotype can reduce features of the allergic airway response in animal models. However, we have limited knowledge of the signals that drive the development of distinct subsets and functional phenotypes of NK cells in the lung and thus the role and therapeutic potential of NK cells in the allergic airway remains unclear. Here we review the potentially diverse roles of NK cells in allergic airway disease, identify gaps in current knowledge and discuss the potential of modulating NK cell function as a treatment strategy in asthma

    êuticas integradas para estas afecções.Objective: to describe current ideas about the relation between upper and lower respiratory tract and to review the epidemiological, immunological, and pathological aspects that support the paradigm of united airways disease. Sources: literature review using the Medline, MD Consult, HighWire, Medscape and Lilacs databases. We used allergic rhinitis and asthma as keywords, and searched articles published in the past 20 years. Summary of the findings: epidemiological evidence includes prevalence of allergic rhinitis in asthmatic patients and vice-versa, results of cross-sectional studies, bronchial hyperresponsiveness in patients with allergic rhinitis, importance of genetic and environmental factors, and the age of onset of atopic disease. Morphological and physiological aspects show structural differences between the nasal and bronchial mucosa, and the mechanisms that could explain the effect of rhinitis on asthma. Immunological aspects including the participation of bone marrow in the production of inflammatory cells and allergic reactions after allergen challenge are the same in allergic rhinitis and asthma. Finally, the results of the therapy for allergic rhinitis in bronchial hyperresponsiveness and in clinical and functional control of asthma are also reported. Conclusions: epidemiological evidence and immunological and pathological aspects suggest that there is a relation between allergic rhinitis and asthma. The paradigm of united airways disease suggests the implementation of an integrated therapeutic approach.

    AIM To explore the effect and safety of budesonide inhalation by nose on combined allergic rhinitis and asthma syndrome (CARAS) . METHODS Eighty-two patients with CARAS were randomly divided into two groups. All patients were treated by atomization pots. The patients in the nose group (n = 40) received budesonide aerosol by nose-suction nozzle, while the others in the mouth group (n = 42) received budesonide aerosol by mouth-suction nozzle. The doses of the two groups were the same and the courses were both 8 weeks. The symptoms scorings, lung function (FEV1, PEF), levels of serum total IgE and eosinophil absolute values were observed before and after the treatment. RESULTS The symptoms scorings of nasal and thorax, the levels of IgE, and the eosinophil absolute values in both groups decreased obviously after the treatment (P 0.05) . The levels of FEV1 and PEF increased significantly in both groups, and those in the nose group were higher ( P < 0.01) . There was no severe adverse reaction in the two groups. CONCLUSION Budesonide inhalation by nose in treating CARAS can obviously improve symptoms and lung functions, reduce serum total IgE level, with few adverse reaction. Budesonide inhalation by nose is superior to inhalation by mouth.%目的 探讨经鼻吸入布地奈德治疗过敏性鼻炎-哮喘综合征(CARAS)的疗效及安全性.方法 82例CARAS急性发作期患者,随机分为2组,均采用口-鼻两用雾化罐.经鼻组(n=40)和经口组(n=42)分别经鼻和经口吸入布地奈德气雾剂,均每次1吸200 μg,早晚各1次,连续治疗8 wk.观察治疗前后症状评分、第一秒用力呼气容积(FEV1)、呼气峰流量(PEF)、血清总IgE、嗜酸粒细胞(EOS)绝对值的变化.结果 治疗后2组鼻部及胸部症状评分、血清总IgE水平、EOS绝对值均下降(P<0.01),经鼻组症状评分、总IgE水平低于经口组(P< 0.05或P<0.01),2组EOS绝对值无显著差异(P>0.05).2组FEV1、PEF水平均升高(P<0.01),经鼻组FEV1

  15. Inhibition of protein kinase C delta attenuates allergic airway inflammation through suppression of PI3K/Akt/mTOR/HIF-1 alpha/VEGF pathway.

    Directory of Open Access Journals (Sweden)

    Yun Ho Choi

    Full Text Available Vascular endothelial growth factor (VEGF is supposed to contribute to the pathogenesis of allergic airway disease. VEGF expression is regulated by a variety of stimuli such as nitric oxide, growth factors, and hypoxia-inducible factor-1 alpha (HIF-1α. Recently, inhibition of the mammalian target of rapamycin (mTOR has been shown to alleviate cardinal asthmatic features, including airway hyperresponsiveness, eosinophilic inflammation, and increased vascular permeability in asthma models. Based on these observations, we have investigated whether mTOR is associated with HIF-1α-mediated VEGF expression in allergic asthma. In studies with the mTOR inhibitor rapamycin, we have elucidated the stimulatory role of a mTOR-HIF-1α-VEGF axis in allergic response. Next, the mechanisms by which mTOR is activated to modulate this response have been evaluated. mTOR is known to be regulated by phosphoinositide 3-kinase (PI3K/Akt or protein kinase C-delta (PKC δ in various cell types. Consistent with these, our results have revealed that suppression of PKC δ by rottlerin leads to the inhibition of PI3K/Akt activity and the subsequent blockade of a mTOR-HIF-1α-VEGF module, thereby attenuating typical asthmatic attack in a murine model. Thus, the present data indicate that PKC δ is necessary for the modulation of the PI3K/Akt/mTOR signaling cascade, resulting in a tight regulation of HIF-1α activity and VEGF expression. In conclusion, PKC δ may represent a valuable target for innovative therapeutic treatment of allergic airway disease.

    Numerous pregnant women suffer from allergic rhinitis, and particular attention is required when prescribing drugs to these patients. In addition, physiologic changes associated with pregnancy could affect the upper airways. Evidence-based guidelines on the management of allergic rhinitis have been published. Medication can be prescribed during pregnancy when the apparent benefit of the drug is greater than the apparent risk. Usually, there is at least one "safe" drug from each major class used to control symptoms. All glucocorticosteroids are teratogenic in animals but, when the indication is clear (for diseases possibly associated, such as severe asthma exacerbation), the benefit of the drug is far greater than the risk. Inhaled glucocorticosteroids (eg, beclomethasone or budesonide) have not been incriminated as teratogens in humans and are used by pregnant women who have asthma. A few H1-antihistamines can safely be used as well. Most oral decongestants (except pseudoephedrine) are teratogenic in animals. There are no such data available for intranasal decongestants. Finally, pregnancy is not considered to be a contraindication for the continuation of immunotherapy.

    Allergic bronchopulmonary aspergillosis (ABPA) is infrequently documented in children with asthma. Although collapse is not uncommon, middle lobe syndrome (MLS) as a presentation of ABPA is rather a rarity. A 9-year-old female child with asthma presented with increase in intensity of symptoms along with a right midzone patchy consolidation on a chest radiograph. In addition, an ill-defined opacity abutting the right cardiac border with loss of cardiac silhouette was noted. A right lateral vie...

    We studied the occurrence of asthma, bronchial wheezing, allergic rhinitis and atopic dermatitis in 295 young men aged 18-19 years. The relationship of these symptoms to the immediate skin test reactivity was also determined. Symptoms indicating past or current allergy and bronchial wheezing were observed in 36%. The cumulative prevalence of asthma was 2.7%, bronchial wheezing 9% in addition, allergic rhinitis (including allergic conjunctivitis) 20%, and atopic dermatitis (including allergic urticaria) 20%. Positive immediate skin prick test reactions were observed in 50% of the population. Allergic rhinitis was most clearly connected with a positive skin test. This study shows that the respiratory disorders, generally considered to be allergic in origin, and atopic dermatitis are more common in Finland than has been assumed. The results are, however, in accordance with the observations made in other industrialized countries. Susceptibility to asthmatic reactions and allergic symptoms should be taken into account, more so than at present, when mudging the capability of a young man to manage compulsory military service.

    The prevalence of sensitization to cat and dog allergens is high in the general population and poses a challenge to the physician managing allergic asthma. Adequate allergen avoidance is difficult to achieve because of the physical characteristics of airborne animal allergens and patient noncompliance. Allergen-specific high-dose subcutaneous immunotherapy has shown benefit in cat-allergic patients with asthma and rhinoconjunctivitis, whereas the data for dog-allergic patients are not as convincing. Alternative immunotherapy approaches including the sublingual route or allergen-derived peptide-based immunotherapy remain experimental. Pharmacotherapy of pet-allergic asthmatic patients requires a stepwise approach following established asthma management guidelines. In addition to short-acting beta-agonists and inhaled corticosteroids, prophylactic antihistamines before anticipated pet exposure, the use of intranasal steroids, and the use of leukotriene antagonists may also be considered as adjunctive therapy in pet-allergic patients with asthma and/or allergic rhinitis. Omalizumab appears to have particular efficacy in pet allergen-induced asthma. Novel therapies such as Fcgamma-Fel d 1 chimeric proteins still have to be evaluated in the human setting.

    Patients with severe asthma have considerable morbidity related to their asthma and are at risk for serious, life-threatening exacerbations. Their management requires an intensive and comprehensive approach, including attention to reducing exposure to environmental inciters of airway inflammation and triggers of symptoms, patient education (including an asthma action plan), and opportunity for close patient-provider communication. Approved medical options include the lipoxygenase inhibitor, zileuton; the anti-immunoglobulin E monoclonal antibody, omalizumab; and bronchial thermoplasty. Nonapproved interventions of potential benefit are ultrahigh-dose inhaled corticosteroids, anticholinergic bronchodilators (tiotropium), macrolide antibiotics, and vitamin D supplementation for the vitamin D-deficient patient. Potentially toxic, "steroid-sparing" therapies such as methotrexate, cyclosporine, and etanercept are best reserved for patients participating in clinical trials. Recognition of specific subtypes of patients with therapy-resistant asthma permits more targeted treatment approaches, such as for aspirin-sensitive asthma, persistent eosinophilic asthma, asthma complicated by allergic bronchopulmonary aspergillosis, asthma with persistent airflow obstruction, and asthma with life-threatening (near fatal) asthmatic attacks. Novel therapies based on an improved understanding of the pathobiology of therapy-resistant asthma are greatly needed.

    Full Text Available Background: Skin prick test (SPT is the most effective diagnostic test to detect IgE mediated type I allergic reactions like allergic rhinitis, atopic asthma, acute urticaria, food allergy etc. SPTs are done to know allergic sensitivity and applied for devising immunotherapy as the therapeutic modality. Materials and Methods: This prospective study was conducted in the department of Immunology and Molecular medicine at SKIMS. A total of 400 patients suffering from allergic rhinitis, asthma and urticaria were recruited in this study. SPT was performed with panel of allergens including house dust mite, pollens, fungi, dusts, cockroach, sheep wool and dog epithelia. Allergen immunotherapy was given to allergic rhinitis and asthmatic patients as therapeutic modality. Results: In our study, age of patients ranged from 6 to 65 years. Majority of patients were in the age group of 20-30 years (72% with Male to female ratio of 1:1.5. Of the 400 patients, 248 (62% had urticaria, 108 (27% patients had allergic rhinitis and 44 (11% patients had asthma. SPT reaction was positive in 38 (86.4% with allergic asthma, 74 (68.5% patients with allergic rhinitis and 4 (1.6% patient with urticaria, respectively. Allergen immunotherapy was effective in 58% patients with allergic rhinitis and 42% allergic asthma. Conclusion: Identifiable aeroallergen could be detected in 86.4% allergic asthma and 68.5% allergic rhinitis patients by SPT alone. Pollens were the most prevalent causative allergen. There was significant relief in the severity of symptoms, medication intake with the help of allergen immunotherapy.

  5. Indoor air and allergic diseases

    Allergies may be the source of a variety of clinical symptoms. With regard to indoor air, however, the subject will be limited to inhalative allergies. These are diseases which are caused and supported by allergens entering the human organism via the respiratory pathway. The fundamentals of the origin of inhalative allergies are briefly discussed as well as the antigen-antibody reaction and the differentiation between different allergic reactions (Types I and II). In addition, the importance of repetitive infections of the upper respiratory tract for the occurrence of allergies of the respiratory system is pointed out. The most common allergies develop at the mucosae of the nose (allergic rhinitis) and of the bronchiale (allergic asthma bronchiale). Their symptomatology is discussed. Out of the allergologically interesting components of indoor air the following are to be considered primarily: house dust, components of house dust (house dust mite, trogoderma angustum, tenebrio molitor), epithelia of animals, animal feeds, mildew and occupational substances. Unspecific irritants (chemico-physical irritations) which are not acting as allergens, have to be clearly separated from these most frequent allergens. As a possibility of treatment for the therapeutist and the patient, there is the allergen prophylaxis, i.e. an extensive sanitation of the patient's environment including elimination of the allergens and, in addition, an amelioration of the quality of the air with regard to unspecific irritants. To conclude, some socio-medical aspects of respiratory diseases are discussed.

    Asthma triggers have been linked to adverse health outcomes in asthma, but little is known about their association with asthma control. Because trigger avoidance is an integral part of successful asthma management, psychological triggers in particular may be associated with suboptimal asthma control, given the difficulty of controlling them. We examined cross-sectional and longitudinal associations of perceived asthma triggers with self-report of asthma control impairment, symptoms, and spirometric lung function (forced expiratory volume in the 1st second, [FEV1]) in 179 adult primary care asthma patients. Perceived asthma triggers explained up to 42.5% of the variance in asthma control and symptoms, but not in FEV1 alone. Allergic triggers explained up to 12.1% of the asthma control and symptom variance, three nonallergic trigger types, air pollution/irritants, physical activity, and infection, explained up to 26.2% over and above allergic triggers, and psychological triggers up to 9.5% over and above all other triggers. Psychological triggers alone explained up to 33.9% of the variance and were the only trigger class that was consistently significant in all final multiple regression models predicting control and symptoms. Psychological triggers also predicted lower asthma control 3-6 months later, although controlling for initial asthma control eliminated this association. In free reports of individually relevant triggers, only psychological triggers were associated with suboptimal asthma control. Trigger factors are important predictors of self-reported asthma control and symptoms but not actual lung function. Particular attention should be directed to psychological triggers as indicators of patients' perceptions of suboptimal asthma control.

    Asthma is a complex disease, involving many different allergic, inflammatory, and environmental components. It is a disease for which patient and family education and a team-based approach are paramount for successful management. Guidelines have been put forth by the National Heart, Lung and Blood Institute, which provide a helpful framework in which to begin to manage patients and to navigate the many medication choices available. It is only through diligent attention to control of asthma symptoms that improved quality of life and prevention of long-term sequelae are possible for the pediatric patient with asthma.

    Holt, Patrick G; Sly, Peter D

    2012-05-04

    Prospective birth cohort studies tracking asthma initiation and consolidation in community cohorts have identified viral infections occurring against a background of allergic sensitization to aeroallergens as a uniquely potent risk factor for the expression of acute severe asthma-like symptoms and for the ensuing development of asthma that can persist through childhood and into adulthood. A combination of recent experimental and human studies have suggested that underlying this bipartite process are a series of interactions between antiviral and atopic inflammatory pathways that are mediated by local activation of myeloid cell populations in the airway mucosa and the parallel programming and recruitment of their replacements from bone marrow. Targeting key components of these pathways at the appropriate stages of asthma provides new opportunities for the treatment of established asthma but, more crucially, for primary and secondary prevention of asthma during childhood.

    Epidemiological studies have reported an increased risk of respiratory diseases in agricultural population, but a protective "farm-effect" has also been reported for asthma. In the AGRICAN cohort, self-reported doctor-diagnosed asthma was analyzed according to allergy, in relation with history of life-time exposure to 13 crops and 5 livestock, pesticide exposure and early life on a farm, taking into account sex, age, education and body mass index. Among the 1246 asthmatics (8.0%), 505 were allergic (3.3%) and 719 non-allergic (4.6%). In multivariate analysis, a significant excess was observed, only for allergic asthma, in vine-growing (OR=1.43, p=0.002), fruit-growing (OR=1.58, p=0.001), greenhouses (OR=1.66, p=0.02), grasslands (OR=1.35, p=0.009), beets (OR=1.52, p=0.003) and horses (OR=1.35, p=0.04). Pesticide use and history of pesticide poisoning were significantly associated with allergic asthma in grassland, vineyards and fruit-growing and with non-allergic asthma in beets. Living on a farm in the first year of life tended to be protective for childhood allergic asthma in farms with livestock (OR=0.72, p=0.07) but deleterious in farms with vineyards, fruit or vegetables (OR=1.44, p=0.07). In AGRICAN, an increased risk of allergic asthma was observed with crop exposure, pesticide use and early life on a farm, especially in vine-growing, grassland, beets, fruit and vegetable-growing.

    Full Text Available Two mouse models were used to assay the antiallergic effects of the velvet antler (VA of Formosan sambar deer (Cervus unicolor swinhoei in this study. The results using the ovalbumin- (OVA- sensitized mouse model showed that the levels of total IgE and OVA-specific IgE were reduced after VA powder was administrated for 4 weeks. In addition, the ex vivo results indicated that the secretion of T helper cell 1 (Th1, regulatory T (Treg, and Th17 cytokines by splenocytes was significantly increased (P<0.05 when VA powder was administered to the mice. Furthermore, OVA-allergic asthma mice that have been orally administrated with VA powder showed a strong inhibition of Th2 cytokine and proinflammatory cytokine production in bronchoalveolar fluid compared to control mice. An increase in the regulatory T-cell population of splenocytes in the allergic asthma mice after oral administration of VA was also observed. All the features of the asthmatic phenotype, including airway inflammation and the development of airway hyperresponsiveness, were reduced by treatment with VA. These findings support the hypothesis that oral feeding of VA may be an effective way of alleviating asthmatic symptoms in humans.

  14. Nasal hyperreactivity and inflammation in allergic rhinitis

    Directory of Open Access Journals (Sweden)

    I. M. Garrelds

    1996-01-01

    Full Text Available The history of allergic disease goes back to 1819, when Bostock described his own ‘periodical affection of the eyes and chest’, which he called ‘summer catarrh’. Since they thought it was produced by the effluvium of new hay, this condition was also called hay fever. Later, in 1873, Blackley established that pollen played an important role in the causation of hay fever. Nowadays, the definition of allergy is ‘An untoward physiologic event mediated by a variety of different immunologic reactions’. In this review, the term allergy will be restricted to the IgE-dependent reactions. The most important clinical manifestations of IgE-dependent reactions are allergic conjunctivitis, allergic rhinitis, allergic asthma and atopic dermatitis. However, this review will be restricted to allergic rhinitis. The histopathological features of allergic inflammation involve an increase in blood flow and vascular permeability, leading to plasma exudation and the formation of oedema. In addition, a cascade of events occurs which involves a variety of inflammatory cells. These inflammatory cells migrate under the influence of chemotactic agents to the site of injury and induce the process of repair. Several types of inflammatory cells have been implicated in the pathogenesis of allergic rhinitis. After specific or nonspecific stimuli, inflammatory mediators are generated from cells normally found in the nose, such as mast cells, antigen-presenting cells and epithelial cells (primary effector cells and from cells recruited into the nose, such as basophils, eosinophils, lymphocytes, platelets and neutrophils (secondary effector cells. This review describes the identification of each of the inflammatory cells and their mediators which play a role in the perennial allergic processes in the nose of rhinitis patients.

    Difficult to control severe asthma is characterized by the persistence of inacceptable symptoms of asthma despite a continuous treatment with at least high doses of inhaled steroids and long acting bronchodilators. The diagnosis is done after a period of observation and some investigations that will allow confirm the diagnosis of asthma, eliminate alternative diagnosis and etiological forms that would be difficult to treat intrinsically (allergic broncho-pulmonary aspergillosis, Churg and Strauss disease, chronic eosinophilic pneumonia, occupational asthma). At the end of this period devoted to diagnosis a systematic approach is set up to take care of these patients. Therapeutic education includes action plans and measures for triggering factors avoidance in order to prevent exacerbations. Comorbidities such as rhinitis, nasal polyposis, gastro-oesophageal reflux and obesity are taken into account. Lastly, the treatment must be adapted according to the patient's preferences and aims, and to the asthma severity. Ultimately in steroid-dependent asthma, the lowest efficient dose is tracked continuously. For these patients, new molecules are needed.

    Asthma and allergic diseases have become one of the epidemics of the 21st century in developed countries. Much of the success of other areas of medicine, such as infectious diseases, lies on preventive measures. Thus, much effort is also being placed lately in the prevention of asthma and allergy. This manuscript reviews the current evidence, divided into four areas of activity. Interventions modifying environmental exposure to allergens have provided inconsistent results, with multifaceted interventions being more effective in the prevention of asthma. Regarding nutrition, the use of hydrolyzed formulas in high-risk infants reduces the incidence of atopic dermatitis, while there is for now not enough evidence to recommend other dietary modifications, prebiotics, probiotics, or other microbial products. Pharmacologic agents used until now for prevention have not proved useful, while there is hope that antiviral vaccines could be useful in the future. Allergen-specific immunotherapy is effective for the treatment of allergic patients with symptoms; the study of its value for primary and secondary prevention of asthma and allergy is in its very preliminary phases. The lack of success in the prevention of these disorders lies on their complexity, which involves many genetic, epigenetic, and environmental interactions. There is a need to identify target populations, involved mechanisms and interactions, and the best interventions. These must be effective, feasible, implementable, and affordable.

    Full Text Available INTRODUCTION: Asthma is an inflammatory, reversible and progressive disease with episodes of exacerbations. Asthma is now considered as single airway disease and hence comprehensive diagnosis, treatment and follow-up of upper and lower respiratory tract is essential. Both the Nasal and Bronchial mucosa are the elements of united airway disease and Eosinophils measured from this mucosa can be an indirect marker of Airway inflammation in asthma. Eosinophil infiltration is hallmark feature of pathogenesis of asthma which is the trigger for the chronic airway inflammation and these are raised in acute exacerbations. Hence assessing Eosinophil is evidence of serological marker for Airway inflammation (AI. Nasal Smear Eosinophils (NSE is used in asthma with Allergic Rhinitis (AR. This study Using Definition of GINA explores the utility of NSE as marker for management of Asthma. METHODS: In this study 100 patients diagnosed with bronchial asthma attending the outpatient department in KIMS were studied. The severity of asthma was assessed as per FEV1 classification- Adapted from 2007 NHLBI Guidelines for the diagnosis and treatment of Asthma Expert panel Report 3. The Statistical analysis was done with SAS 9.2, SPSS 15.0, Stata 10.1, Med Calc 9.0.1, Systat 12.0 and R environment ver.2.11.1.software.

    Asthma and allergic diseases have become one of the epidemics of the 21st century in developed countries. Much of the success of other areas of medicine, such as infectious diseases, lies on preventive measures. Thus, much effort is also being placed lately in the prevention of asthma and allergy....... This manuscript reviews the current evidence, divided into four areas of activity. Interventions modifying environmental exposure to allergens have provided inconsistent results, with multifaceted interventions being more effective in the prevention of asthma. Regarding nutrition, the use of hydrolyzed formulas...... in high-risk infants reduces the incidence of atopic dermatitis, while there is for now not enough evidence to recommend other dietary modifications, pre-biotics, probiotics, or other microbial products. Pharmacologic agents used until now for prevention have not proved useful, while there is hope...

    Full Text Available Allergy is a common immune disorder characterized by raised IgE levels, which leads to clinical disorders such as asthma, rhinitis and eczema. Our understanding of the pathogenesis of allergic disease is largely dependent on our current understanding of the related pathophysiology and the available technology. Recent advances in molecular biology techniques have allowed a rapid and accurate identification of polymorphisms in various genes that may be important for determining the susceptibility to allergic disorders. In this review, we present some developments in genetic studies of allergic disease with particular focus on asthma and atopy in the Japanese population.

    Full Text Available Incidence and prevalence of allergic diseases during childhood have significantly increased in developed countries over the last 20 to 30 years. The role of the inhalant allergens in exacerbating respiratory allergies has been demonstrated. House dust mites are the main causative agents. Environmental pollution and climate changes, along with other factors, have contributed to the increase of these diseases. Among such conditions the most frequent in children are respiratory allergies, particularly allergic rhinitis and bronchial asthma. The current article presents a review on allergic rhinitis, bronchial asthma and IgE levels in children, emphasizing on epidemiology and trigger factors.

    Objective To investigate the prevalence of allergy to two common species of cockroaches(Periplaneta americana and Blatteila germaniea) among outpatients with bronchial asthma(asthma) and allergic rhinitia from an epidemiological perspective,and to provide evidences for further research on insecthypersensitivity. Methods A total of 6081 outpatients with asthma and allergic rhinitis, registered to clinicsof respiratory diseases, pediatrics or allergic diseases in 25 Three Grade-A hospitals, were included in thestudy. These patients were studied using a standardized questionnaire and skin prick tests for cockroachallergens. Results Among patients with asthma and allergic rhinitis, response to one of the cockroachescorrelated well with that to another,as did the grades of response ( P <0.001). The overall rate of responseto Periplaneta americana was 26.34% vs 19.37% to Blattella germanica. Higher rate of response was foundin the south as compared with northern and eastern regions of China. In those allergic to cockroach,grade 2reactions appeared predominant, with strong-positive outcomes seen only in rare cases. Positive allergy toPeriplaneta americana and Blattella germanica was identified in 28% and 19% of males vs 25% and 15% offemales,30% and 24% of adults vs 23% and 14% of children,respectively. About 90% cockroach-allergicpatients concurrently tested positive to house dust mites. Conclusions Cockroach appears to be one of majorallergens among patients with asthma and allergic rhinitis. The rate of response is higher with Periplanetaamericana than with Blattella germaniea. Higher prevalence of allergy to cockroach is found in males than infemales,and in adults than in children.

    Introduction. Asthma is the commonest chronic condition of children. Diagnosis of this condition remains difficult. Many surrogate markers are used, such as documenting evidence of atopy. Method. A random sample of asthmatic children and their mothers attending the Children's Chest and Allergy Clinic at Steve Biko Academic Hospital were enrolled. Children were classified as having atopic or nonatopic asthma. Mothers completed a questionnaire to uncover atopic features. Results. Along with their mothers, 64 children with atopic asthma and 36 with nonatopic asthma were studied. The proportion of children with atopic asthma does not differ for mothers with and without a positive SPT (P = 0.836), a history of asthma (P = 0.045), symptoms suggestive of an allergic disease (P = 1.000), or who were considered to be allergic (P = 0.806). The odds ratio of a child having atopic asthma when having a mother with a doctor diagnosed history of asthma is 4.76, but the sensitivity is low (21.9%). Conclusion. The data demonstrates that all maternal allergic or asthmatic associations are poor predictors of childhood atopic asthma. Despite the increased risk of atopic asthma in a child to a mother that has a doctor diagnosis of asthma (OR 4.76 P = 0.045), this is a poor predictor of atopic asthma (sensitivity 21.9%).

    Bronchial asthma is an airway inflammatory disease which many kinds of cells and cellular compo-nents are involved in. It is characterized by airway inflammation, airway remodeling and airway hyperresponsiveness. However, the pathogenesis of bronchial asthma is very complex. Therefore in this paper, the important roles of Lyn ki-nase and endoplasmic reticulum stress in the pathogenesis of bronchial asthma are reviewed.%支气管哮喘是多种细胞及细胞组分参与的气道炎症性疾病,主要以气道炎症和气道重塑、气道高反应性为特征;然而其发病机制十分复杂,本文对Lyn激酶和内质网应激在支气管哮喘的发病机制中的重要作用进行综述.

    Full Text Available Abstract Asthma belongs to the category of classical allergic diseases which generally arise due to IgE mediated hypersensitivity to environmental triggers. Since its prevalence is very high in developed or urbanized societies it is also referred to as "disease of civilizations". Due to its increased prevalence among related individuals, it was understood quite long back that it is a genetic disorder. Well designed epidemiological studies reinforced these views. The advent of modern biological technology saw further refinements in our understanding of genetics of asthma and led to the realization that asthma is not a disorder with simple Mendelian mode of inheritance but a multifactorial disorder of the airways brought about by complex interaction between genetic and environmental factors. Current asthma research has witnessed evidences that are compelling researchers to redefine asthma altogether. Although no consensus exists among workers regarding its definition, it seems obvious that several pathologies, all affecting the airways, have been clubbed into one common category called asthma. Needless to say, genetic studies have led from the front in bringing about these transformations. Genomics, molecular biology, immunology and other interrelated disciplines have unearthed data that has changed the way we think about asthma now. In this review, we center our discussions on genetic basis of asthma; the molecular mechanisms involved in its pathogenesis. Taking cue from the existing data we would briefly ponder over the future directions that should improve our understanding of asthma pathogenesis.

  8. Eosinophils in fungus-associated allergic pulmonary disease

    Full Text Available Asthma is frequently caused and/or exacerbated by sensitization to fungal allergens, which are ubiquitous in many indoor and outdoor environments. Severe asthma with fungal sensitization is characterized by airway hyperresponsiveness and bronchial constriction in response to an inhaled allergen that is worsened by environmental exposure to airborne fungi and which leads to a disease course that is often very difficult to treat with standard asthma therapies. As a result of complex interactions among inflammatory cells, structural cells, and the intercellular matrix of the allergic lung, patients with sensitization to fungal allergens may experience a greater degree of airway wall remodeling and progressive, accumulated pulmonary dysfunction as part of the disease sequela. From their development in the bone marrow to their recruitment to the lung via chemokine and cytokine networks, eosinophils form an important component of the inflammatory milieu that is associated with this syndrome. Eosinophils are recognized as complex multi-factorial leukocytes with diverse functions in the context of allergic fungal asthma. In this review, we will consider recent advances in our understanding of the molecular mechanisms that are associated with eosinophil development and migration to the allergic lung in response to fungal inhalation, along with the eosinophil’s function in the immune response to and the immunopathology attributed to fungus-associated allergic pulmonary disease.

    Chronic exposure to farm environments is a risk factor for nonallergic lung disease. In contrast to allergic asthma, in which type 2 helper T cell (Th2) activation is dominant, exposure to farm dust extracts (FDE) induces Th1/Th17 lung inflammation, associated with neutrophil infiltration.

    Full Text Available Asthma is a chronic inflammatory disease that imposes a substantial burden on patients, their families, and the community. Although many aspects of the pathogenesis of classical allergic asthma are well known by the scientific community, other points are not yet understood. Experimental asthma models, particularly murine models, have been used for over 100 years in order to better understand the immunopathology of asthma. It has been shown that human microbiome is an important component in the development of the immune system. Furthermore, the occurrence of many inflammatory diseases is influenced by the presence of microbes. Again, experimental models of asthma have helped researchers to understand the relationship between the microbiome and respiratory inflammation. In this review, we discuss the evolution of murine models of asthma and approach the major studies involving the microbiome and asthma.

    Full Text Available Genetically modified (GM foods are evaluated carefully for their ability to induce allergic disease. However, few studies have tested the capacity of a GM food to act as an adjuvant, i.e. influencing allergic responses to other unrelated allergens at acute onset and in individuals with pre-existing allergy. We sought to evaluate the effect of short-term feeding of GM Bacillus thuringiensis (Bt-maize (MON810 on the initiation and relapse of allergic asthma in mice. BALB/c mice were provided a diet containing 33% GM or non-GM maize for up to 34 days either before ovalbumin (OVA-induced experimental allergic asthma or disease relapse in mice with pre-existing allergy. We observed that GM-maize feeding did not affect OVA-induced eosinophilic airway and lung inflammation, mucus hypersecretion or OVA-specific antibody production at initiation or relapse of allergic asthma. There was no adjuvant effect upon GM-maize consumption on the onset or severity of allergic responses in a mouse model of allergic asthma.

    Immunoglobulin E (IgE) antibodies and mast cells have been so convincingly linked to the pathophysiology of anaphylaxis and other acute allergic reactions that it can be difficult to think of them in other contexts. However, a large body of evidence now suggests that both IgE and mast cells are also key drivers of the long-term pathophysiological changes and tissue remodeling associated with chronic allergic inflammation in asthma and other settings. Such potential roles include IgE-dependent regulation of mast-cell functions, actions of IgE that are largely independent of mast cells and roles of mast cells that do not directly involve IgE. In this review, we discuss findings supporting the conclusion that IgE and mast cells can have both interdependent and independent roles in the complex immune responses that manifest clinically as asthma and other allergic disorders.

    AIM: To investigate the expression and clinical significance of miR-155 in the peripheral blood CD4+ T cells of patients with allergic asthma. METHODS; The expression of pre-mature BIC transcript and its processed microRNA miR-155 in the CD4 + T cells from 50 patients with allergic asthma and 20 healthy individuals were measured using real-time PCR. The correlation of miR-155 expression and the disease severity of asthma was analyzed. The ability of miR-155 to influence Thl/Th2 differentiation was examined in vitro. RESULTS; The expression of pre-mature BIC and miR-155 in the CD4+ T cells of asthma patients significantly decreased compared to those in normal controls (P< 0.01). Furthermore, the expression of BIC in moderate and severe asthma patients was lower than that in normal controls (P<0. 05). Among mild, moderate, severe asthma patients, BIC expression showed no statistical significance, but miR-155 expression of severe asthma patients was lower than that in mild asthma patients (P<0.05). The expression level of miR-155 was positively correlated to FEVl/pred (%) ( P < 0. 01). miR-155 over-expression was found to promote CD4+ T cells to Thl differentiation, while of miR-155 was found to induce CCM* T cells to Th2 differentiation. CONCLUSION; The decreased expression level of miR-155 is correlated to asthma disease severity. It is suggested miR-155 plays an important role in development of asthma.%目的:探讨过敏性哮喘患者外周血CD4+T细胞中miR-155及其前体基因BIC的表达及临床意义.方法:应用实时荧光定量聚合酶链反应检测不同严重程度哮喘患者50例及健康对照20例外周血CD4+T细胞中BIC及miR-155的表达水平,并且与哮喘患者临床指标进行相关性分析;运用过表达或抑制,探讨miR-155在CD4+T细胞体外分化中的作用.结果:哮喘患者组BIC及miR-155的表达较对照组显著降低(P<0.01),中、重度哮喘患者的BIC表达均低于对照组(P<0.05),轻、中

    Objective To evaluate the effects of dust mite allergen-specific immunotherapy combined with standardized management on prevention and cure in children with asthma and allergic rhinitis and analyze the reasons of the asthma and allergic rhinitis symptom exacerbation during specific immunotherapy. Methods One hundred and two children with established diagnosis of allergic asthma and allergic rhinitis to dust mite were enrolled in this study from january 2006 to december 2010, of whom 78 children received the treatment with specific immunotherapy (SIT) combined with standardized management for 2 to 4 year (as the test group) and the other 24 served as the control group with inhaled corticosteroids according to Global Initiative for Asthma (GINA) and Allergic Rhinitis and its Impact on Asthma (ARIA) in the same time. At the beginning, 6 months, 1 year, 2 years of the treament and 1 year after the treament,the clinical symptom and acute episode, pulmonery function (Peak Expiratory Flow, PEF) and Chinese children asthma control test (Ch-CACT) of the asthmatic children, symptem scores and Visual Analogue Scale( VAS) of allergic rhinitis were analyzed, while respiratory tract infection of all the patients were recorded at the second year and after 1 year of the treatment. The reasons of the asthma and allergic rhinitis symptom exacerbation during dust mite allergen-specific immunotherapy were analyzed. The data were analyzed by SPSS15.0. Results Compared with control group, the frequency of acute episode, the frequency of respiratory tract infection in test group were significantly decreased at the 2 years of the treament and 1 year after the treament. The PEFof asthmasic children were obviously improved in the test group at the 2 years of the treament and 1 year after the treament and the Ch-CACT were more higher in the test group than the control group at 1 year after the treament.

    Administration of human bone marrow-derived mesenchymal stem cells (BM-MSCs) significantly alleviates allergic airway inflammation. There are no studies that refer to the role of microRNAs (miRNAs) after the BM-MSCs treatment in airway allergic inflammation. We induced a mouse model of asthma and performed the transplantation of BM-MSCs. We analyzed aberrant miRNAs and key immune regulators using both miRNA and messenger RNA (mRNA) polymerase chain reaction (PCR) arrays. We identified that 296 miRNAs were differently expressed after the induction of asthma and/or the treatment of BM-MSCs, in which 14 miRNAs presented the reverse variation tendency between asthma induction and BM-MSCs transplantation. Mmu-miR-21a-3p, mmu-miR-449c-5p, and mmu-miR-496a-3p were further confirmed to be differently expressed with additional samples and quantitative real-time PCR. With an mRNA PCR array, we identified 19 genes to be involved in the allergy induction and the administration of BM-MSCs. Further target genes analysis revealed that mmu-miR-21a-3p was significantly correlated with the immune regulator activin A receptor, Type IIA (Acvr2a). Mmu-miR-21a-3p had opposite expression with Acvr2a after asthma and BM-MSCs treatment. Acvr2a had binding sites for miR-21a for both mice and human, suggesting that miR-21/Acvr2a axis is conserved between human and mice. Dual-luciferase reporter assay showed that mmu-miR-21a-3p negatively regulated the transcript of Acvr2a. In addition, has-miR-21a inhibitor significantly increased the expression of Acvr2a mRNA in BEAS-2B cells under lipopolysaccharide stimulation. Our results suggest that there were different miRNA and mRNA profiles after asthma induction and BM-MSCs treatment, and the miR-21/Acvr2a axis is an important mechanism for the induction of asthmatic inflammation.

    In the discussion on possible adverse effects of air pollution upon human health one has to distinguish between out-door and in-door environment. The most frequent pollutants in out-door air over industrialized areas are particulate substances, sulfur dioxide, nitrous oxide, carbonmonoxide, ozone and lead. Most of these substances have direct irritating effects on mucous surfaces. Hypersensitivity reactions have been described against sulfur dioxide and sulfites occurring as asthma, urticaria or anaphylactoid reactions. In-door air pollution is of much greater practical importance for a variety of diseases. Apart from physio-chemical irritants and microbial organisms leading to infections, organic allergens (e.g. house dust mites, moulds, animal epithelia) can induce a variety of allergic diseases via different pathomechanisms.

    Asthma deaths are uncommon, but have recently increased in some countries due to problems in the management of the disease. Morbidity rates show large variations, which can be attributed to differences in defining the disease, but also to genuine variations, with a trend towards less asthma in northern Europe. It has been suggested that allergic diseases as a whole, and asthma in particular, may exhibit an upward secular trend. Risk factors include a genetic background and environmental triggering factors. The importance of genetic factors is illustrated by family studies and by extreme prevalence rates observed in some communities. Environmental factors include rapid air pollution variations which act as a trigger for asthma attacks. However, at levels currently prevailing in western Europe, air pollutants do not induce a higher incidence of asthma. Altitude generates a gradual decrease in Dermatophagoides, thus explaining both the clinical improvement in asthmatics living in altitude and a lower prevalence of asthma in populations born and living there. Among the other aero-allergens, grass pollens plays a major role in spring, elicitating asthma attacks. Some natural allergens transformed by man (castor bean, soja) can be responsible for asthma epidemics.

    Cysteinyl leukotrienes (Cys-LTs) are mediators released in asthma and virus-induced wheezing. Corticosteroids appear to have little or no effect on this release in vivo. Cys-LTs are both direct bronchoconstrictors and proinflammatory substances that mediate several steps in the pathophysiology...... of chronic asthma, including inflammatory cell recruitment, vascular leakage, and possibly airway remodeling. Blocking studies show that Cys-LTs are pivotal mediators in the pathophysiology of asthma. Cys-LTs are key components in the early and late allergic airway response and also contribute to bronchial...... obstruction after exercise and hyperventilation of cold, dry air in asthmatics. LT modifiers reduce airway eosinophil numbers and exhaled nitric oxide levels. Together these findings support an important role for the Cys-LTs in the asthma airway inflammation. Cys-LT receptor antagonists (Cys...

    Objective: Examined the impairment of regulatory T cells in cord blood from offspring of allergic asthmatic mothers. Methods: Cord blood mononuclear cells from 62 healthy neonates ( 40 healthy mothers and 22 allergic asthmatic mothers ) were isolated , and cultured with stimuli: lipid A ( TLR4 ligands ), peptidoglycan ( Ppg-TLR2 ligands ), mitogen ( PHA, phytohemagglutinin ) and Dermatophagoides pteronyssinusl. And then the amount of CD4 + CD25 + Foxp3 + T cells was acounted with flow cytometry; cytokine concentrations were measured in supernatants by LUMINEX technology; the suppressive function of regulatory T cells were examinated by isolating and culturing of CD4 + CD25 + T cells and CD4 + CD25 ~ T cells in vitro. Results: Cord blood from offspring of allergic asthmatic mothers showed Ppg-induced fewer regulatory T cells ( CD4 + CD25 + Foxp3 + T,P =0. 03 ) and lower IL-10 secretion ( P =0. 03 ). Furthermore, the suppressive capacity of regulatory T cells was impaired in PHA-induced division and proliferation of T effector cells in cord blood of offspring from allergic asthmatic mothers ( P =0.05 ). Meanwhile, the suppressive capacity of regulatory T cells to IL-13 production by effector cells was partially impared ( P = 0.07 ). Conclusion: In offspring of allergic asthmatic mothers, regulatory T cells amount, and suppressive function were impaired at birth, which maybe potentially contribute to the the susceptibility to allergic diseases.%目的:研究母亲过敏性哮喘病史对新生儿调节性T细胞的影响.方法:收集62例胎儿脐带血[40例健康母亲(对照组),22例母亲有过敏性哮喘病史(哮喘组)],分离单个核细胞进行体外培养,每例样品均分别给予以下4种刺激:类脂A(LpA)-Toll样受体4的配体,肽多糖(Ppg)-Toll样受体2的配体,植物血凝素(PHA),屋尘螨提取物.培养3天后,应用流式细胞技术检测CD4+CD25+Foxp3+调节性T细胞数量;Luminex流式荧光仪检测特异性细胞因

    Full Text Available In a 1993 survey, allergic rhinitis was identified as the most common allergic disease in Hong Kong, affecting 29.1% of schoolchildren. Recently (1995, the International Study of Asthma and Allergies in Childhood (ISAAC also reported 44.5% current rhinitis among Hong Kong teenagers. Our objective was to study the aetiology of allergic rhinitis in Hong Kong using serological tests of allergen sensitization. In 57 allergic rhinitis patients and in the same number of age- and sex-matched controls the following were measured: serum total IgE, mixed aeroallergen IgE (Phadiatop™ and specific IgE versus house dust mite (HDM, cockroach, cat and dog dander, mould mixture (Penicillium, Cladosporium, Aspergillus and Alternaria species and four local pollens (Bermuda grass, Timothy, ragweed and mugwort. Compared with controls, allergic rhinitis patients (26 males, 31 females; mean (± SD age 25 ±11 years had a significantly elevated serum total IgE concentration (mean ± SEM: 496 ± 88 vs 179 ± 38 kU/L and an increased proportion of positive Phadiatop (95 vs 33% and specific IgE tests versus HDM (90 vs 44% and cockroach (42 vs 9%; Mann-Whitney U-test and χ2 tests all P < 0.005. There was no significant difference in sensitization to other allergens tested. House dust mite and cockroach are ubiquitous in Hong Kong with a warm, humid climate and crowded living conditions. Their identification as aetiological agents of allergic rhinitis should help in the development of environmental strategies for reducing the inhalant allergen load to prevent and control this prevalent and costly health problem in our community.

  13. New concept in allergy: Non-allergic rats becomes allergic after induced by Porphyromonas gingivalis lipopolysaccharide

    2013-06-01

    Full Text Available Background: As a theory, seemingly it is impossible that allergic diseases, including asthma, are the result of exposure to a transmissible agent. The fact that nearly all children with asthma are allergic, but only a small proportion of allergic children have asthma, at least raises the possibility that other factors are involved. Interestingly, non-allergic children become allergic after their parents came from working in allergic people for several months. Recent research revealed that periodontal pathogens are also transmissible from mother and caregivers to infants.Therefore, it is logical that non-allergic children could become allergic after exposed to periodontopathic bacteria. However, the mechanism is still unclear. Purpose: The objective of this study is to verify a new concept that non-allergic rat may become allergic after exposed to Porphyromonas gingivalis lipopolysaccharide. Methods: Randomized control series design experimental study was conducted to 24 male Wistar rats, two experimental groups and one control group. One group was subjected to intrasulcular injection of PgLPS1435/1450. Tissue examination were done for allergy biomarkers with peroxidase immunohistochemistry for leukotriene C4 (LTC4 and eosinophilic cationic protein (ECP in bronchus tissue. Serum level examination of interleukin 4 (IL-4, and immunoglobulin E (IgE was done with ELISA. Data were analyzes using ANOVA. Results: after four days, LTC4 and ECP expression increased significantly (p=0.001; even insignificant, IL-4 and IgE serum level also increased. Conclusion: PgLPS is able to stimulate immunocompetent cells which changed the host immune response of non-allergic rats. Therefore, it is possible that they become allergic.Latar belakang: Menurut teori, penularan penyakit alergi termasuk asma merupakan hal yang mustahil.

    2012-02-03

    Aspergillus fumigatus is one of the most ubiquitous of the airborne saprophytic fungi. Allergic bronchopulmonary aspergillosis (ABPA) is a syndrome seen in patients with asthma and cystic fibrosis, and is characterized by hypersensitivity to chronic colonization of the airways with A. fumigatus. We report the case of a patient with ABPA presenting with pleural effusion. A 27-year-old male was referred with recurrent right pleural effusion. Past medical history was remarkable for asthma, allergic sinusitis, and recurrent pleurisy. Investigations revealed peripheral eosinophilia with elevated serum immunoglobulin E and bilateral pleural effusions with bilateral upper lobe proximal bronchiectasis. Precipitating serum antibodies to A. fumigatus were positive and the A. fumigatus immediate skin test yielded a positive reaction. A diagnosis of ABPA associated with bilateral pleural effusions was made and the patient was commenced on prednisolone. At review, the patient\\'s symptoms had considerably improved and his pleural effusions had resolved. ABPA may present with diverse atypical syndromes, including paratracheal and hilar adenopathy, obstructive lung collapse, pneumothorax and bronchopleural fistula, and allergic sinusitis. Allergic bronchopulmonary aspergillosis is a rare cause of pleural effusion and must be considered in the differential diagnosis of patients presenting with a pleural effusion, in particular those with a history of asthma.

    AIM: To investigate whether birch pollen allergy symptoms are linked with gut microbiota changes and whether probiotics have an effect on these. METHODS: Forty seven children with confirmed birch pollen allergy were randomized to receive either a probiotic combination of Lactobacillus acidophilus ( L. acidophi lus) NCFMTM (ATCC 700396) and Bifidobacterium lactis ( B. lactis) Bl-04 (ATCC SD5219) or placebo in a double-blind manner for 4 mo, starting prior to onset of the birch pollen season. Symptoms were recorded in a diary. Blood samples were taken for analysis of cytokines and eosinophils. Fecal samples were analysed for microbiota components, calprotectin and IgA. Nasal swabs were taken for analysis of eosinophils.RESULTS: The pollen season induced a reduction in Bifidobacterium, Clostridium and Bacteroides which could not be prevented by the probiotic intervention. During the intervention, significantly higher numbers 106 bacteria/g feces ( P < 0.0001) were observed in the probiotic group compared to the placebo group. During May, there was a tendency for fewer subjects,(76.2% vs 95.2%, P = 0.078) to report runny nose,while during June, fewer subjects, 11.1% vs 33.3%,reported nasal blocking in the probiotics group ( P = 0.101). Concomitantly, fewer subjects in the probiotic group had infiltration of eosinophils in the nasal mucosa compared to the placebo group, 57.1%vs 95% ( P = 0.013). Eye symptoms tended to be slightly more frequent in the probiotic group, 12.5 d [interquartile range (IQR) 6-18] vs 7.5 d (IQR 0-11.5)( P = 0.066) during May. Fecal IgA was increased in the placebo group during the pollen season; this increase was prevented by the probiotics ( P = 0.028).CONCLUSION: Birch pollen allergy was shown to be associated with changes in fecal microbiota composition. The specific combination of probiotics used was shown to prevent the pollen-induced infiltration of eosinophils into the nasal mucosa, and indicated a trend for reduced nasal symptoms.

  16. Asthma pharmacotherapy.

    Schofield, Minka L

    2014-02-01

    Asthma is a chronic inflammatory disease of the airway that leads to airway obstruction via bronchoconstriction, edema, and mucus hypersecretion. The National Asthma Education and Prevention Program has outlined evidence-based guidelines to standardize asthma therapy and improve outcomes. The initial recommendation of choice for persistent asthmatic patients is an inhaled corticosteroid (ICS). Long-acting beta-2 agonists in combination with ICS, oral corticosteroids, leukotriene modifiers, and anti-IgE therapeutic options can be considered for patients with persistent or worsening symptoms. Many novel therapies are being developed, with an emphasis on anti-inflammatory mechanisms, gene expression, and cytokine modification.

    Full Text Available Asthma during adolescence can induce social, psychological, and behavioral problems. We examined the impact of asthma and other allergic diseases on psychological symptoms and health risk behaviors among South Korean adolescents.In this population-based cross-sectional study, 3192 adolescents (10-18 years of age participating in the 2008-2011 Korean National Health and Nutrition Examination Survey were enrolled. Psychological problems associated with clinically diagnosed asthma, allergic rhinitis, and atopic dermatitis were assessed using questionnaires and surveys. Data was analyzed using logistic regression to determine the association of depression with allergic disease while controlling for age, sex, body mass index, smoking experience, and alcohol use.Asthma and atopic dermatitis were associated with a higher prevalence of depression (17.2% and 13%, respectively. After adjusting for the covariates, asthma patients were approximately two times as likely to have depression as non-allergic participants (odds ratio, 1.81; 95% confidence interval, 1.22-2.68. Psychosocial stress significantly increased in the following order: no allergy, any allergy without asthma, asthma only, and asthma with any allergy (p for linear trend = 0.01. The asthma without other allergies group showed the highest prevalence of cigarette smoking (p = 0.007.In this study, asthma with or without other allergies was significantly related to increases in depression, psychosocial stress, and smoking experience. Thus, care should be taken to adjust treatment to account for the psychological symptoms and health risk behaviors common among asthmatic adolescents.

    Full Text Available Abstract Background Laminins are a group of proteins largely responsible for the anchorage of cells to basement membranes. We hypothesized that altered Laminin chain production in the bronchial mucosa might explain the phenomenon of epithelial cell shedding in asthma. The aim was to characterize the presence of Laminin chains in the SEBM and epithelium in allergic and non-allergic asthmatics. Patients and methods Biopsies were taken from the bronchi of 11 patients with allergic and 9 patients with non-allergic asthma and from 7 controls and stained with antibodies against the Laminin (ln chains alpha1-alpha5, beta1-beta2 and gamma1-gamma2. Results Lns-2,-5 and -10 were the main Laminins of SEBM. The layer of ln-10 was thicker in the two asthmatic groups while an increased thickness of lns-2 and -5 was only seen in allergic asthmatics. The ln gamma2-chain, which is only found in ln 5, was exclusively expressed in epithelial cells in association with epithelial injury and in the columnar epithelium of allergic asthmatics. Conclusion The uncoordinated production of chains of ln-5 in allergic asthma could have a bearing on the poor epithelial cell anchorage in these patients.

    Full Text Available Background Allergic rhinitis is one of the most common chronic diseases of childhood. Recent studies have suggested that having fewer siblings was associated with allergic rhinitis and atopic diseases in children. Previous studies also indicated that older siblings was associated with higher incidence of allergic rhinitis.Objectives To assess for a possible association between number of siblings and allergic rhinitis and to assess for an effect of birth order on allergic rhinitis in children.Methods We performed a cross-sectional study among school children aged 7 to 15 years, in the West Medan District from July to August 2011. Children with moderate or high risk of allergy were included. Subjects were divided into two groups, those with <3 siblings or ≥3 siblings. Children with acute respiratory tract infections, septal deviation, choanal atresia, nasal polyps, nasal tumors, or nasal foreign body were excluded. Risk of allergy was determined using the Indonesian Pediatrics Allergy Immunology Working Group trace card scoring system. Identification of allergic rhinitis and evaluation of its severity were done by use of the International Study of Asthma and Allergies in Childhood (ISAAC core questionnaire. Allergic rhinitis was diagnosed based on history, physical examination, and anterior rhinoscopy.Results A total of 78 subjects were enrolled. Allergic rhinitis was significantly higher in children with <3 siblings than those with ≥3 siblings (OR 10.33; 95%CI 3.569 to 29.916. Furthermore, allergic rhinitis was significantly higher in first-born children than in their younger siblings (P=0.0001.Conclusion Larger number of siblings and non-first-born children are associated with lower incidence of allergic rhinitis in children.

    The current scientific research is continuously aiming at identifying new therapeutic targets with the purpose of modifying the immune response to allergens. The evolution in immunological methods has led to the identification of immunoglobulin E (IgE) as both a diagnostic biomarker and potential therapeutic target in allergic diseases, such as allergic rhinitis. Allergen immunotherapy has been used for more than 100 years to treat allergic diseases and it is today considered the only disease-modifying treatment capable of inducing a long-lasting immunological and clinical tolerance toward the causal allergen. During the past 20 years, major advances have been made in understanding the molecular and cellular mechanisms of allergen tolerance in humans. Moreover, there has been considerable progress in allergen extract modifications and additions to standard extracts. The recognition that IgE plays a pivotal role in basic regulatory mechanisms of allergic inflammation has recently stimulated research into the therapeutic potential of directly targeting this antibody. Omalizumab, the most advanced humanized anti-IgE monoclonal antibody, is currently approved for the treatment of uncontrolled allergic asthma and chronic spontaneous urticaria. Interesting results also arise from studies in which omalizumab was administered in patients with allergic rhinitis. The aim of this review is to provide an update on current findings on immunological and clinical effects of allergen immunotherapy and anti-IgE therapy, which have been shown to have synergistic modes of action for the treatment of allergic rhinitis.

    Histamine has been reported to play an important role in pathogenesis of bronchial asthma. However, H1-blockers are not recommended as the first drug for asthma therapy in the guidelines. Histamine may play various roles in allergic airway inflammation through the H1 receptor (H1R), H2R, and H4R in immune cells including T lymphocytes and dendritic cells. We therefore evaluated its role in allergic airway inflammation with the use of histamine-deficient mice. The results suggested that histamine plays a role in the prevention of goblet cell hyperplasia. Organic cation transporter-3 (OCT-3) is thought to be a transporter of histamine. Polymorphism of OCT-3 {R120R (T/C)} was associated with the severity of asthma. Recently, it has been proposed that both asthma and allergic rhinitis should be treated as a single airway disease. Comorbidity of asthma and allergic rhinitis is very high (70-80%) and they share similar allergic inflammation. H1-blockers are recommended as first-line drugs to treat allergic rhinitis in the guidelines. Therefore H1-blockers are strongly recommended for patients with both asthma and allergic rhinitis.

    CT of the thorax done during acute severe asthma in two paediatric patients demonstrated central bronchiectasis, a sine qua non for the diagnosis of allergic bronchopulmonary aspergillosis. Bronchography, regarded as the gold standard, was done subsequently on recovery. A comparative segmental analysis revealed that CT was able to identify immediately 24 of 27 segments which showed central bronchiectasis on bronchography. Early diagnosis with the aid of CT enabled immediate intervention which may have helped to prevent further lung damage in the paediatric patients. (orig.).

    The incidence of allergies has recently been increasing worldwide. Immunoglobulin E (IgE)-mediated hypersensitivity is central to the pathogenesis of asthma, hay fever and other allergic diseases. Ginger (Zingiber officinale Roscoe) and its extracts have been valued for their medical properties including antinausea, antiinflammation, antipyresis and analgesia properties. In this study, we investigated the antiallergic effects of ginger and 6-gingerol, a major compound of ginger, using a mouse allergy model and primary/cell line culture system. In mice with ovalbumin (OVA)-induced allergic rhinitis, oral administration of 2% ginger diet reduced the severity of sneezing and nasal rubbing by nasal sensitization of OVA and suppressed infiltration of mast cells in nasal mucosa and secretion of OVA-specific IgE in serum. 6-Gingerol inhibited the expression of not only Th2 cytokines but also Th1 cytokines in OVA-sensitized spleen cells. Accordingly, 6-gingerol suppressed in vitro differentiation of both Th1 cells and Th2 cells from naïve T cells. In addition, 6-gingerol suppressed both superantigen staphylococcal enterotoxin B (SEB)- and anti-CD3-induced T cell proliferation. 6-Gingerol also abrogated PMA plus ionomycin- and SEB-induced IL-2 production in T cells, suggesting that 6-gingerol affected T cell receptor-mediated signal transduction rather than the antigen-presentation process. Indeed, 6-gingerol inhibited the phosphorylation of MAP kinases, calcium release and nuclear localization of c-fos and NF-κB by PMA and ionomycin stimulation. Thus, our results demonstrate that 6-gingerol suppresses cytokine production for T cell activation and proliferation, thereby not causing B cell and mast cell activation and resulting in prevention or alleviation of allergic rhinitis symptoms.

  12. Hematopoietic Processes in Eosinophilic Asthma.

    Salter, Brittany M; Sehmi, Roma

    2017-01-24

    Airway eosinophilia is a hallmark of allergic asthma and understanding mechanisms that promote increases in lung eosinophil numbers is important for effective pharmaco-therapeutic development. It has become evident that expansion of hemopoietic compartments in the bone marrow promotes differentiation and trafficking of mature eosinophils to the airways. Hematopoietic progenitor cells egress the bone marrow and home to the lungs, where in-situ differentiative processes within the tissue provide an ongoing source of pro-inflammatory cells. In addition, hematopoietic progenitor cells in the airways can respond to locally-derived alarmins, to produce a panoply of cytokines thereby themselves acting as effector pro-inflammatory cells that potentiate type 2 responses in eosinophilic asthma. In this review, we will provide evidence for these findings and discuss novel targets for modulating eosinophilopoietic processes, migration and effector function of precursor cells.

    Full Text Available Allergic respiratory disorders are fairly common visiting cases in pediatrics outpatient department (OPD. With an appropriate history and detailed examination, diagnosis may not be problematic. Routine investigation may not contribute much to the final diagnosis but may help in ruling out other possibilities. This study was done to evaluate sensitivity and specificity of blood or nasal eosinophilia in subjects suffering from allergic respiratory disorders and also to assess the feasibility of nasal cytogram which is a simple, economical and reliable investigation in allergic respiratory disorders. This is a prospective clinical correlation study of patients attending outpatient department. 100 subjects aged between 2-18 years of either sex were selected for the estimation of eosinophil count in nasal and peripheral smear in allergic respiratory disorders. All allergic respiratory cases based on eosinophillia. The nasal and blood eosinophilia were compared with each other and clinical findings of allergic rhinitis with or without asthma were studied. In this study peak age incidence was seen between 11-18 years and it was more common in males. Rhinorrhoea, pale mucosa and nasal obstruction were common findings in allergic rhinitis with bronchial asthma. Nasal eosinophilia was seen in 52.4% and 64.9% of cases of allergic rhinitis and allergic rhinitis with asthma respectively. Blood eosinophilia was seen in 54% and 56.8% of cases of allergic rhinitis with asthma respectively. Nasal cytogram which is a simple, economical and non- invasive procedure can be used as an alternative to invasive peripheral smear eosinophilia as both are equally efficacious in diagnosing allergic respiratory diseases.

It has been clearly reported that the prevalence of these diseases has been on the rise for the last few decades, but at different rates, in various areas of the world. This paper discusses the epidemiology of allergic diseases among children and their negative impact on affected patients, their families, and societies. These effects include the adverse effects on quality of life and economic costs. Medical interest has shifted from tertiary or secondary prevention to primary prevention of these chronic diseases among high-risk infants in early life. Being simple, practical, and cost-effective are mandatory features for any candidate methods delivering these strategies. Dietary therapy fits this model well, as it is simple, practical, and cost-effective, and involves diverse methods. The highest priority strategy is feeding these infants breast milk. For those who are not breast-fed, there should be a strategy to maintain beneficial gut flora that positively influences intestinal immunity. We review the current use of probiotics, prebiotics, and synbiotics, and safety and adverse effects. Other dietary modalities of possible potential in achieving this primary prevention, such as a Mediterranean diet, use of milk formula with modified (hydrolyzed proteins, and the role of micronutrients, are also explored. Breast-feeding is effective in reducing the risk of asthma, allergic rhinitis, and atopic eczema among children. In addition, breast milk constitutes a major source

    Extrinsic allergic alveolitis (synonym: hypersensitivity pneumonitis) is caused by inhaling antigenic aerosols which induce hypersensitivity responses in susceptible individuals. It is an interstitial inflammatory disease affecting the distal, gas-exchanging parts of the lung, in contrast to allergic asthma where the inflammation is more proximal, affecting the conducting airways. The aims of this review are to describe current concepts of the immunology of this model of lung inflammation, to describe some of the constitutional and environmental characteristics which affect disease susceptibility and development, and to describe topics for prospective study.
