Abstract:

Abstract

Background: More than 300 million people around the word have reported asthma, and of those, 17 million lived in the USA and of those, 12 million were adults. However, the prevalence of asthma varied between countries, ethnicity, place of residents and even between refugees and immigrants.

Objective: The study examined the relationship between environmental air pollution and its impact on lung function, tested among a vulnerable group of adult Arab Americans with diagnosed asthma by their primary health care physics.

Methods: 76 asthmatic adults Arab American from greater Detroit area were studied (mean age 64.5±7.43 years; mean years in USA 24±4.45; 48 female) during the summer and winter of 2013-2014 for self-reported respiratory symptoms and lung function tests, with no loss of participants.

Results: In the last 3 moth, 35.5% of participants reported poor air quality; 84.25% was concerned about annoying odors; 85.3% was concerned about black particles/dust falling from the sky; 84.2% reported poor visibility in the community; 85..5% were concerned about the effect on health from air pollution (the participants related all the above to air pollution). Participant’s perceived major triggers of asthma as follow: 94.1% exercise, 93.4% sudden weather changes especially cold weather, 89.5% air pollution, 86.8% dust or smoke from cigarettes, 65.8% wood smoke fireplace/stove. The overall asthma was higher in the winter. However 34.7% of the participants in summer were hospitalized for asthma compared to 22.7% in winter. The mean number of upland doctor visits for asthma decline from 1.41 (SD 1.49) in winter to 1.27 (1.49; p=n.s.). There were no statistical significant between summer and winter in FEV1 (L) it was in FEV1/FVC and the ratio between FEV1/FVC decreased from a mean of 0.83 (SD 0.12) in the summer to 0.78 (0.15, p<0.001) in the winter.

Conclusion: The follow up of the asthmatic Arab American study showed clearly that air pollution had an impact on asthma among vulnerable population who are current residents in a heavily polluted area of Detroit. We recommend primary healthcare physicians to advise their asthmatic patients to increase their attention to their respiratory health from the effect of the external and internal (home) environmental exposures and also from some cultural habits, e.g., water-pipe smoking, which will be critical for effective public health measures.

Keynote: Differential role of T-helper 2 cells and group-2 innate lymphoid cells in allergic airway inflammation

Time : 10:50-11:25

Conference Series Allergy-Clinical Immunology 2016 International Conference Keynote Speaker Rudi W Hendriks photo
Biography:

Rudi W Hendriks is the Head of the Experimental Research Laboratory of the Department of Pulmonary Medicine of the Erasmus MC Rotterdam, Netherlands. His main line of research is the differentiation program of lymphocytes in health and disease, in particular the regulation of differentiation and function of T helper subsets and group-2 innate lymphoid cells in the context of type-II immunity and the role of aberrant B and T cell activation in autoimmunity and interstitial lung disease.

Abstract:

Abstract

Allergic asthma is a chronic inflammation of the airways mediated by an adaptive type-2 immune response. In house dust mite (HDM)-driven allergic airway inflammation both T helper-2 (Th2) cells and group-2 innate lymphoid cells (ILC2) are major producers of IL-5 and IL-13. We found that in HDM-challenged mice the induction of ILC2 required prior sensitization with HDM. ILC2 induction was dependent on T-cells, whereby activation of ILC2 and Th2 cells was concomitant. In this HDM-driven allergic asthma model, ILC2 are therefore not an early source of Th2 cytokines but rather contribute to type-2 inflammation in which Th2 cells play a key role. Next, we used GATA3-YFP knock-in mice for direct in situ visualization of GATA3+ Th2 cells and ILC2s. Confocal microscopy revealed that Th2 cells and ILC2 occupied distinct locations in lungs from mice with HDM-driven allergic airway inflammation: ILC2s were scattered underneath the mucosa and Th2 cells were present within clusters of lymphocytes. We produced epigenetic maps of FACS-sorted GATA3+ Th2 cells and ILC2s isolated from mediastinal lymph nodes and broncho-alveolar lavage of GATA3-YFP mice with an allergic airway inflammation. Chromatin immunoprecipitation and deep-sequencing (Chip-Seq) experiments revealed a remarkably similar genome-wide histone-3 lysine-4 dimethylation (H3K4Me2) active chromatin signature in in vivo activated Th2 cells and ILC2s. However, particular loci showed significant differences between the two cell types, including loci associated with allergic inflammation, ILC2 plasticity and metabolic homeostasis. Taken together, these findings indicate novel biological roles for ILC2s in asthma distinct from Th2 cells.

She has published papers in reputed journals and presented in national and international meetings.

Abstract:

The prevalence of adverse food reactions (AFR) in dogs is increasing; it is therefore important to explore novel causal pathways. Results of studies in human and mice have shown that increasing n-6 PUFA-rich oils in the diet enhances the risk to develop allergic diseases. The aims of this study were to investigate the association of AFR with vegetable oils n-6 PUFA-rich intake in dogs, with food preparations (homemade versus commercial diet or both) and with regular use of treats. Data on dietary intake of 204 privately owned dogs with skin disease were obtained from a food survey. The use of oil was recorded in 24 of 204 (11.8%) dogs included in the study, in 4 on 19 dogs with FA (21%), 2 on 10 (20%) with FA and DA, 5 on 35 (14.3%) with DA and 13 on 134 with other conditions (9.7%). The frequency of the oil consumption was significantly higher in dogs with AFR than in dogs with other diagnoses (P<0.05). Sixty-two of 204 dogs (30.1%) were fed homemade diet, 96 (47.1%) commercial diet and 46 (22.6%) both of them. No statistical difference was found between dogs that developed AFR and the others. Fourty-six dogs of 204 (25.6%) received regularly treats. The frequency of dogs with treats was significantly higher in dogs with AFR (37.9%) than in other diseases (20%; p<0.05). In conclusion, dietary vegetable oils rich in n-6 PUFA and the regular administration of treats may enhance the susceptibility to AFR in dogs.

Biography:

Dr. Kunimoto had graduated from Wakayama Medical College at 1987 and completed his Ph.D. study at 1994. He is an Otolaryngologist. He had presented many study about upper respiratory diseases, focal infection on tonsil, cancer related Epstein-Barr virus and immune response analysis using molecular biological technique at that time. Recently, he has had an office in Hiroshima city since 2004, and now former chairperson of Asa Otolaryngology and member of management committee of Hiroshima Otolaryngology. Additionally, he had also belonged to Hiroshima University since 2004.

Abstract:

In 2014, an update to a meta-analysis of heptavalent pneumococcal conjugate vaccine (PCV7)  effects on acute otitis media (AOM) was reported in the Cochrane collection and one of major conclusion was that the PCV7 had modest beneficial effects in terms of changes in AOM episodes and total number of visits to medical institutions by children. We have same results in Japanese children using the Japan Medical Data Center Claims Database. The Japanese guidelines for AOM in children recommend classifying AOM by age, manifestations and local findings. Myringotomy is recommended for moderate-grade cases with severe local findings, severe-grade cases, and treatment-resistant cases. We have previously conducted a retrospective multicenter study in the Asa Area of Hiroshima City, Japan to investigate changes in the number of myringotomies performed to treat AOM after public funded inoculation. The myringotomy rate per child-year in <5-year-old children decreased by 29.1% in 2011 and by 25.2% in 2012 compared to the mean rate performed in the 3 years prior to the introduction of public funding in the multicenter study. Our results suggest the public benefit of PCV7 in reducing the AOM morbidity with less financial burden of myringotomy. In addition, this vaccine may help prevent AOM from aggravation with severe clinical manifestations. We will present the next data about this hypothesis.

Abstract:

Background & Aim: The prevalence of food allergy is increasing all over the world and varies in different geographical locations. This study was performed to assess allergic sensitization against various food materials among Saudi patients clinically presenting with food allergy.rnrnPatients & Methods: Data for the presence of food specific IgE antibodies were collected retrospectively from 280 Saudi patients screened between October 2012 and February 2014. These patients presented in the allergy clinic at King Khalid University Hospital, Riyadh with clinical signs and symptoms of food allergy. Out of the total 92 patients were found to have food specific circulating antibodies. This group of patients comprised of 67 (72.8%) males and 25 (27.2%) females with 78 (84.8%) children of <12 years and 14 (15.2%) adults (mean age 9.04±7.71 years). Food specific IgE antibodies were quantified by Radioallergosorbent test (RAST) using Pharmacia ImmunoCAP 250 analyzer.rnrnResults: The most frequently sensitizing food allergens were milk in 57 (61.96%) patients followed by, egg white in 55 (59.78%) patients, wheat in 42 (45.65%) patients and peanut in 35 (38.04%) patients. Male children were consistently more sensitized against egg white (47.4% vs. 15.3; p≤0.0002), egg yolk (33.3 vs. 7.6; p≤0.0002), milk (47.4 vs. 22.1; p≤0.001), wheat (37.5 vs. 12.4; p≤0.0006) and peanut (37.5% vs. 11%; p≤0.0007) compared to females. Milk sensitization was high among children whereas sensitization due to egg white was high in adults.rnrnConclusion: Patients were frequently sensitized against milk, egg white, wheat and peanut particularly the male children.rn

Abstract:

Background: Different delivery modes may affect the susceptibility to allergic diseases. It is still unknown whether early intervention with probiotics would counteract this effect.rnrnObjectives: The effect of different delivery modes on immune status and nasal symptoms was investigated on established allergic rhinitis (AR) mouse model. In addition, the immunoregulatory effects and mechanisms of different feeding manners with Bifidobacterium breve (B. breve) were examined.rnrnMethods: Live lyophilized B. breve was orally administered to BALB/c mice born via vaginal delivery (VD) or cesarean delivery (CD) for 8 consecutive weeks, after which they were sensitized by ovalbumin (OVA) to establish experimental AR. Nasal symptoms, serum immunoglobulins, cytokines, splenic percentages of CD4+CD25+Foxp3+ regulatory T (Treg) cells and nasal eosinophil infiltration were evaluated.rnrnResults: Compared with VD mice, mice delivered via CD demonstrated more serious nasal symptoms, higher concentrations of OVA-specific immunoglobulin (Ig) E, more nasal eosinophils and lower percentages of splenic CD4+CD25+Foxp3+Treg cells after establishing experimental AR. These parameters were reversed by administering B. breve shortly after birth. However, the effect of B. breve did not differ between different delivery modes.rnrnConclusion: CD aggravates the nasal symptoms of AR mice compared to VD. This is the first report that oral administration of B. breve shortly after birth can significantly alleviate the symptoms of AR mice born via both deliveries, probably via activation of the regulatory capacity of CD4+CD25+Foxp3+Treg cells.rn

Abstract:

Refine the structure of squamous cells and the smooth muscle linings of the bronchial tubes through a method of structural bio-mechanical means (RRT). It is a unique system of redistributing the balance of tissue in resolving adverse bio-mechanical conditions such as asthma or COPD in restricted airways. It recreates the proper balance of the lung’s pleura, bronchus, bronchioles and the associated smooth muscle. Plus, because the balance of the epithelial lining fluid is tightly regulated, the tightness of the airways regulates the particulates and pathogens that get into the system. Therefore, it is imperative to free up the epithelium layers within the bronchus itself. Then by directly involving bio-mechanical forces to stratified squamous epithelium and the smooth muscle system, it can be changed when subjected to the proper use of mechanical force. Releasing the tension from the bronchus to the bronchiole creates a direct path of intervention from the bronchus, of the entire gas field, to the respiratory b’s to within the alveolar ducts themselves. This method produces an immediate release of more gas into the alveolar ducts, oxygenating the entire organism. The use of biomechanical movements and depth of contact has not yet been fully determined, further research is recommended and is ongoing. The system is based on working in the fascial system. By recreating the body’s originally designed space, the body immediately regains full use of the lungs. The techniques usually take 10-15 minutes at most. People stay at work, need no time off and stay productive.

Abstract:

Background: Airway wall remodeling is a major pathology of allergic asthma and is independent of inflammation. This pathology can be induced by purified human IgE, without the presence of allergens by activating airway smooth muscle cells (ASMC) to proliferation and depose extracellular matrix.

Objective: We assessed if circulating IgE obtained from allergic asthma patients in the absence of allergens stimulates ASMC remodeling and if this can be prevented by anti-IgE antibodies.

Methods: In vitro, human ASMC were exposed to serum of either healthy controls, or patients with allergic asthma, non-allergic asthma, or atopic non-asthma patients. Proliferation and deposition of collagens and fibronectin were determined after 3 and 5 days.

Results: Serum from patients with allergies significantly stimulated ASMC proliferation at 3 and 5 days, the deposition of collagen type-I within 48 hours and of fibronectin within 24 hours. One hour pre-incubation of sera with Omalizumab prevented these effects in allergic serum. In contrast, the anti-IgE antibody had no significant effect on serum from healthy donors or patients with non-allergic asthma. Furthermore, these effects were not modified by the presence of allergens.

Conclusion: The data provides experimental evidence that anti-IgE antibodies neutralize the pro-remodeling activity suggesting that IgE is a major contributor ASMC mediated airway wall remodeling in asthma.

Abstract:

Immune diseases are caused by suppression or over stimulation of the immune system. It is a well-known fact that allergic and autoimmune diseases are less common in the developing world than the industrialized world. This lead to the “Hygiene Hypothesis” formulated by Strachan, which postulated that lack of early childhood exposure to infectious increases susceptibility to allergic diseases by suppressing the natural development of the immune system. The hygiene hypothesis however cannot explain the rise in incidence of several TH1-mediated autoimmune diseases such as inflammatory bowel diseases, multiple sclerosis etc. This lead to the “Old Friends Hypothesis” by Graham Rook which postulates that vital microbial exposures are "Old Friends" such as helminthes, non-pathogenic environmental pseudocommensal bacteria or certain gut commensals and probiotics that could persist in small hunter gatherer groups as microbiota. However what is conveniently forgotten is the fact that environment we live is not only a physical one but it also has an important mental/psychological component. Urbanization brings it with many psychological, emotional problems. There are many studies which show a relationship between psychological stress and parameters of the immune system. In Eastern philosophy which originated in India consider that all things in the universe, both living and non-living are joined together as everything in the universe is actually made of the same natural elements. Diet, exercise, profession and relationships all have the potential to create physical, emotional or spiritual imbalances. This imbalance causes a lack of harmony and makes us more susceptible to disease.

Abstract:

Sarcoidosis is a multi-organ systemic inflammatory disease of unknown etiology that is characterized by non-caseating epithelioid granuloma formations with the lung most commonly affected. The increased frequency of activated lung CD4+ T cells with a Th1 cytokine profile in sarcoidosis patients is accompanied by a reduced proportion and/or impaired function of regulatory T cells (Tregs). Here we evaluated the expression of the inducible co-stimulator (ICOS) on lung and blood CD4+ T cell subsets in sarcoidosis patients with different prognosis, by flow cytometry. Samples from the deep airways were obtained by bronchoalveolar lavage (BAL). We show that Tregs from the inflamed lung of sarcoidosis patients were characterized by a unique ICOS high phenotype. High-level ICOS expression was restricted to Tregs from the inflamed lung and was absent in blood Tregs of sarcoidosis patients as well as in lung and blood Tregs of healthy volunteers. In addition, lung Tregs exhibited increased ICOS expression compared to sarcoid-specific lung effector T cells. Strikingly, ICOS expression on Tregs was particularly high in the lungs of Lofgren's syndrome (LS) patients who present with acute disease which often resolves spontaneously. Moreover, blood monocytes from LS patients revealed increased ICOS-L levels compared to healthy donors. Sarcoidosis was associated with a shift towards a non-classical monocyte phenotype and the ICOS-L high phenotype was restricted to this particular monocyte subset. We propose a potential implication of the ICOS/ICOS-L immune-regulatory axis in disease activity and resolution and suggest further evaluating the suitability of ICOS as biomarker for the prognosis of sarcoidosis.

Abstract:

Griscelli syndrome (GS) is a rare autosomal recessive disorder, first described by Griscelli in 1978 as partial albinism with cellular immunodeficiency characterized by a silver-gray sheen of the hair and the presence of large clusters of pigment in the hair shaft and the occurrence of either a primary neurological impairment or a severe immunological disorder. Immunodeficiency leads to frequent pyogenic infections and episodes of acute fever, neutropenia and thrombocytopenia, pigmentary dilution of hair, hypogammaglobulinemia and deficient antibody production. Three types of this disorder are distinguished by its genetic cause and pattern of signs and symptoms. GS type 1 is caused by mutation in the MYO5A gene, causing severe primary neurological impairment such as developmental delay and mental retardation, in addition to the distinctive skin and hair coloring. Affected individual may have intellectual disability, seizures and weak muscle tone (hypotonia) eye and vision abnormalities. Patients with GS type 2 caused by mutation in RAB27A gene, associated with a primary immunodeficiency due to an impairment of T cell and natural killer cytotoxic activity which leads to susceptibility to recurrent infections. They also develop an immune condition called hemophagocytic lymphohistiocytosis (HLH), in which the immune system produces too many activated immune cells called T-lymphocytes and macrophages (histiocytes). Over-activity of these cells can damage organs and tissues throughout the body, causing life threatening complications if the condition is untreated. Patients with GS type 2 do not have the neurological abnormalities like type 1. Light skin and hair coloring are the only features of GS type 3. People with this form of the disorder do not have neurological abnormalities or immune system problems. Light microscopy examination of the hair shaft is an easy way to diagnose GS, typically with a large cluster of pigment unevenly distributed in the hair shaft predominantly in the medulla. Electron microscopy of skin biopsy shows massive accumulation of mature Melanosomes within the melanocytes of the skin, contrasting with spare pigment in the adjacent keratinocytes. Prevalence of GS is unknown in Saudi Arabia; type 2 appears to be the most common of the three known types. GS type 1 and 2 are reported in the literature however GS type 3 from Saudi Arabia is rarely reported. Here we are reporting a case of GS type 3 from KSA.

Abstract:

Introduction: Food allergy is characterized by an adverse immunologic response to a dietary protein. Food-related reactions are associated with a wide spectrum of signs and symptoms that may involve many organs and systems such as skin, gastrointestinal, respiratory tract and cardiovascular system. IgE-mediated food allergies are more common among infants and young children than adults. The prevalence in children under the age of 3 is in the range of 5-8%. Identification of the common food allergens in each population can provide effective preventive and curative clues.

Objectives: The aim of this study was to determine the most common food allergens in children of Isfahan province, Iran.

Materials & Methods: Eighty six children with age in the range of 2 months to 13 years old with skin, respiratory or gastrointestinal symptoms, thought to be due to food allergy, were referred to Milad Diagnostic Laboratory (Isfahan, Iran) by pediatricians. Total serum IgE and serum-specific immunoglobulin E (IgE) were measured using immunoCAP FEIA-IgE (Phadia) method based on physicians’ requests. All parents were given written consent.

Results: Of eighty six children those checked for food allergy, 46 (53.48%) showed allergy to specific foods. The most frequent food allergen in all patients with decreasing prevalence were wheat (19.34%), cow’s milk (16.96%), egg white (11.4%), nuts mix 1 (including: Peanut, Hazelnut, Brazilian nutmeg, Almonds and Coconut) (9.02%), tomato (6.88%), soybean (6.14%), beef (5.64%), sea food mix (5.34%), nuts mix 2 (including: American Walnut, Almond Hindi, Pistachios, Walnut) (4.45%), barely (3.76%), chicken (2.38%), egg yolk (1.58%), sheep milk (1.58%), goat milk (1.58%), cheese (1.58%), curry (Sanata Maria) (0.79%), corn (0.79%), sesame seed (0.79%).

She is currently enrolled as PhD student in the lab of Veterinary Immunology, Gent University, Belgium, where she studies food allergy in dogs. She has published papers in reputed journals and presented in national and international meetings.

Abstract:

The prevalence of adverse food reactions (AFR) in dogs is increasing; it is therefore important to explore novel causal pathways. Results of studies in human and mice have shown that increasing n-6 PUFA-rich oils in the diet enhances the risk to develop allergic diseases. The aims of this study were to investigate the association of AFR with vegetable oils n-6 PUFA-rich intake in dogs, with food preparations (homemade versus commercial diet or both) and with regular use of treats. Data on dietary intake of 204 privately owned dogs with skin disease were obtained from a food survey. The use of oil was recorded in 24 of 204 (11.8%) dogs included in the study, in 4 on 19 dogs with FA (21%), 2 on 10 (20%) with FA and DA, 5 on 35 (14.3%) with DA and 13 on 134 with other conditions (9.7%). The frequency of the oil consumption was significantly higher in dogs with AFR than in dogs with other diagnoses (P<0.05). 62 of 204 dogs (30.1%) were fed homemade diet, 96 (47.1%) commercial diet and 46 (22.6%) both of them. No statistical difference was found between dogs that developed AFR and the others. 46 dogs of 204 (25.6%) received regularly treats. The frequency of dogs with treats was significantly higher in dogs with AFR (37.9%) than in other diseases (20%; p<0.05). In conclusion, dietary vegetable oils rich in n-6 PUFA and the regular administration of treats may enhance the susceptibility to AFR in dogs.
