Der volle Inhalt der QuelleThe general aim of the thesis was to assess the complex role of nutritional factors in asthma, with a first part focused on diet, and a second part focused on obesity. Diet – The objective was to compare dietary patterns based on principal component analysis (PCA) to patterns based on confirmatory factor analysis (CFA). The analysis was performed among 30,589 women from the E3N study (epidemiological cohort study among women of the Mutuelle Générale de l’Education Nationale). Whether PCA or CFA was used, 3 patterns were derived. For each pattern, we reported different correlations between food groups and dietary patterns when using PCA or CFA, leading to different associations between dietary patterns with socio-economic characteristics and adult-onset asthma. Obesity – The first objective was to assess the joint and independent, time-dependent, roles of physical activity and obesity on asthma using marginal structural models. Among 15,352 women from E3N, analyses showed that obesity was related causally to current asthma with symptoms independently of physical activity, whereas no association was reported for physical activity. The second objective was to assess the modifying role of overweight in the association between domestic exposure to cleaning sprays and current asthma. Among 304 women from E3N, analysis showed that among women without anti-inflammatory therapy, the effect of spray use on asthma was higher in overweight women. CFA should be considered for the assessment of dietary patterns in nutritional epidemiology. Obesity may lead to asthma independently of physical activity, and may increase the deleterious effect of other environmental factors of asthma

Der volle Inhalt der QuelleL’objectiu general de la tesi fou avaluar el paper dels factors nutricionals en l’asma. El primer objectiu fou comparar l’anàlisi de components principals (PCA) amb l’anàlisi factorial confirmatori (CFA) per identificar patrons de dieta. Comparat amb els patrons obtinguts amb PCA, els patrons obtinguts amb CFA mostraven major correlació amb grups d’aliments i característiques sociodemogràfiques, i aconseguien millor predicció de la incidència d’asma. El segon objectiu fou avaluar l’efecte conjunt de l’activitat física i l’obesitat en l’asma, utilitzant models marginals estructurals. Els resultats mostraren que l’obesitat es relaciona causalment amb els símptomes d’asma independentment de l’activitat física, mentre que no es va trobar cap efecte de l’activitat física. El tercer objectiu fou estudiar el paper modificador del sobrepès en l’associació entre l’ús de pulveritzadors de neteja domèstica i la presència d’asma. Les anàlisis mostraren que l’efecte de l’ús dels pulveritzadors era més gran en dones amb sobrepès i tractament antiinflamatori

Der volle Inhalt der QuelleLes cellules CD4+ T à antigènes spécifiques transfèrent par adoption l'inflammation pulmonaire constituées principalement de lymphocytes et d'éosinophiles. L'habileté de celles-ci à transférer des cellules T pour induire l'inflammation est dépendante de leur expression de cytokines Th2. De manière à mieux comprendre le mécanisme par lequel les cellules T transmises par adoption induisent l'inflammation pulmonaire, nous avons choisi de moduler l'expression de GATA-3) ou l'activité de (STAT-6) des deux régulateurs-clés de production de cytokine Th2. Afin de modifier l'expression de GATA-3 dans les cellules T destinées au transfert par adoption, nous avons utilisé un rétrovirus recombinant concentré avec une filtration par centrifugeuse. Ce procédé a dramatiquement augmenté leurs titres et ainsi leur habileté à transduire les cellules CD4+ T en culture primaire. Nous avons utilisé un rétrovirus recombinant qui encode la GATA-3 et / ou la protéine fluorescente verte (EGFP). En couplant in vitro la stimulation d'antigènes avec la transduction par vecteur viral, nous avons généré des cellules CD4+ T à antigènes spécifiques exprimant de l'EGFP seul ou bien de la GATA-3 et de l'EGFP. Lorsque transféré dans un rat qui avait subséquemment été provoqué avec des antigènes, ces cellules CD4+ T induisent une réaction aux inflammations pulmonaires avec une augmentation des lymphocytes et éosinophiles. Cette réaction inflammatoire fut accrue chez les animaux recevant les cellules T surexprimant la GATA-3. L'analyse des cellules infiltrantes a aussi révélé que bien que les cellules EGFP+ étaient présentes dans les poumons suivant la provocation par antigènes, elles étaient constituées seulement d'une petite fraction de cellules CD4+ T recrutées dans les poumons. Ainsi, la GATA-3 amplifie la réaction inflammatoire des poumons induite par antigènes en augmentant l'habileté des cellules T à antigènes spécifiques à recruter

Der volle Inhalt der QuelleIntroductionThe reason for the higher asthma incidence in women during the reproductive years is still unknown. The gender switch in asthma incidence around puberty has been put forward to suggest a role of female sex hormones in asthma. However, there are limited findings in the natural history of asthma after age of 50 and whether the transition through menopause is associated with change in asthma incidence is unknown.The objective of this thesis was to investigate the natural history of allergic and non-allergic asthma in women in term of incidence, evolution with aging (menopause) and risk factors of asthma in women with a focus on the gender differences.Materials and methodsThe gender differences in allergic and non-allergic asthma was assess in 2.125 men and 2.298 women free of asthma at baseline (aged 20-44) followed for 20 years as a part of the European Community Respiratory Health Survey (ECRHS). The association between asthma incidence and menopausal status was assessed in 67,872 women free of asthma at baseline (aged 41-68 years) and regularly followed-up as a part of the French E3N cohort. Association between the domestic use of cleaning bleach and allergic and non-allergic asthma have been assess in 607 women (mean age 44 years) participating in the first follow-up of the Epidemiological Study on the Genetics and Environment of Asthma (EGEA). Allergy was define by a positive skin prick test.ResultsWith data from ECRHS we showed that the incidence of non-allergic asthma was higher in women as compared to men (Odds Ratio (OR): 4.0 [95% Confident Interval (CI95%): 2.5-6.5]. The female predominance was less marked for allergic asthma (OR :1.7 [IC :1.0-2.7]). However, in asthmatics there was no gender differences in the progression of asthma. With data from E3N we showed that among normal-weight women, there was no difference in asthma incidence between premenopausal and naturally postmenopausal women of the same age (Hazard Ratio(HR) :1,1 [0,8-1,3]). However, in obese women, the transition through menopause (HR: 1.9[1.0-3.7]) and the later period after menopause (HR:2.1 [1.1-4.1]) were associated with a higher asthma incidence. Surgically post-menopausal women were also at increased risk of developing asthma (HR:1.33[95%CI 1.01-1.75]).In EGEA, only 2% of men and 37% of women reported using bleach weekly for home cleaning. Women using bleach were at increased risk for non-allergic asthma (OR 3.3; 95%CI 1.5-7.1), and more particularly for non-allergic adult-onset asthma (OR 4.9; 95%CI 2.0-11.6). No association was observed for allergic asthma. Among women with asthma, frequent use of bleach was significantly associated with higher blood neutrophil cell counts.ConclusionGender differences in asthma incidence still persist in older adults however, changes in female sex hormones level occurring around natural menopause was not independently associated with change in asthma incidence in women. Our findings do not support the hypothesis that female sex hormones are independently associated with asthma incidence. The interaction between metabolic and hormonal factors and the gender difference in environment factor such as bleach use might explain the gender switch in asthma incidence around puberty and the female predominance in asthma more particularly for non-allergic asthma in adulthood

Der volle Inhalt der Quellewho had never been diagnosed with asthma, identified from birth records accessed through the Health Department of Western Australia. Information, regarding the respiratory conditions experienced by the study children and characteristics of the home, was collected using a standardised questionnaire. The questionnaire consists of questions about potential risk factors for asthma and these factors were grouped in three categories. The first category included information on personal and social factors such as age and gender of the child, and mother's and father's educational level. The second category was related to personal susceptibility factors such as child's allergy, parental and sibling's asthma, eczema and hay fever. The last category included environmental exposure in the house such as parental and visitors smoking inside the house, exposure to gas heating and cooking, kerosene space heaters, open fireplaces, and pets. Other questions related to environmental exposure were the presence of air conditioning, humidifiers, and type of floor covering in the child's bedroom and the living room. Measurements of indoor nitrogen dioxide (NO[subscript]2), formaldehyde (HCHO), volatile organic compounds (VOCs), particulate matter (PM[subscript]10), and house dust mite exposure were made on two occasions over one year, winter (middle June through September 1998) and summer (December 1998 through March 1999), Indoor temperature and relative humidity were also measured. The atopic status of the children was assessed by skin prick tests to common allergens.The study results indicated that age, gender, family history of asthma, atopy and domestic exposure to indoor environmental factors were significant predictors of asthma early in life. The study found that indoor exposure to formaldehyde, volatile organic compounds and house dust mite significantly increased the risk of ++
having asthma. Presence of air conditioning appeared to be a protective factor for asthma.In conclusion, the study results confirmed the role of susceptibility factors in asthma and show that indoor environmental factors contribute as risk factors for asthma in early stage of fife. The observation that exposure to indoor air pollutants in early childhood is associated with asthma suggests the possibility that irritants in indoor air might be involved in the initiation phase of asthma. Since the quality of the indoor environment is potentially modifiable there might be opportunities for intervention to reduce asthma symptoms. In order to counteract the increasing prevalence in asthma, the significance of the indoor environment where children grow and spend most of their time need to be given greater attention.

Der volle Inhalt der QuelleDurante la última decada, numerosos estudios resaltaron un mayor riesgo de asma entre los trabajadores que usan productos de limpieza y, más concretamente, entre trabajadores de limpieza. Se ha hipotetizado que la exposición a irritantes puede ser la causa subyacente. Dada la gran población expuesta a estos agents, no solo en el trabajo, es crucial entender los mecanismos de los síntomas respiratorios asociados a la limpieza, así como los factores de riesgo de asma para alcanzar un ambiente más saludable en casa y en el trabajo. EPIASLI-2 se diseñó para esclarecer dichos puntos en relación con asma y con dermatitis de manos. En 2007-08 se realizó un muestreo en dos etapas entre las empresas de limpieza de Barcelona y sus empleados. Tras el estudio transversal de dichas empresas, se realizó un estudio caso-control entre los trabajadores de limpieza. La exposición y la sintomatología se midieron con cuestionarios. Además, obtuvimos muestras de sangre, condensado de aire exhalado, FeNO, función pulmonar y tests de hiperreactividad bronquial. El proyecto resultó en un artículo de revisión y tres artículos originales, todos ellos publicados o en revisión en reconocidas revistas internacionales. Encontramos un incremento en la prevalencia de síntomas de asma y dermatitis de manos entre los limpiadores que usaban irritantes y productos multiusos así como entre los que trabajaban en hospitales y áreas abiertas. La evaluación de los biomarcadores de inflamación y la función pulmonar sugieren que la inflamación eosinofílica no tiene un papel importante. Sin embargo, los mecanismos inmunológicos de asma no deben ser ignorados. La población expuesta a productos de limpieza de alto riesgo debe ser vigilada y la exposición debe ser reducida cuando no evitada.

Der volle Inhalt der QuelleAsthma is a disease with a complex etiology, involving multiple genetic and environmental factors, and with an important role of the interplay of these factors through gene-environment interactions. In this thesis I aimed to advance our knowledge on the importance of genetic polymorphisms and their interaction with environmental data for the occurrence of asthma and related phenotypes (atopy and bronchial hyperreactivity). This objective was developed through the replication of genetic associations previously reported, the assessment of gene-environment interactions and the identification of new susceptibility genes using genome-wide analysis based on a pooling DNA strategy. The thesis was, mostly, performed within the European Community Respiratory Health Survey (ECRHS). This cohort has information and DNA samples from approximately 5,000 adult subjects followed-up for 9 years, with extensive questionnaires on respiratory symptoms, clinical evaluations and information on environmental exposures. This thesis replicates previous effects on asthma of polymorphisms in TNFA and NPSR1 genes. In addition, interactions have been established between TNFA and obesity, NQO1 and air-pollution, and NPSR1 and age at onset of asthma. The approach based on genome-wide analysis of DNA pools identified the SGK493 region being associated with atopy. This thesis contributes to the understanding of the etiology of asthma through the identification and replication of genetic associations and gene-environment interactions.

Der volle Inhalt der QuelleThe overall aims of our studies were to identify risk factors for respiratory symptoms and asthma in indoor environment but even to look at some personal risk factors such as body mass index and gastroesophageal reflux. The study population is based on participants of the European Community Respiratory Health Survey I and II.
In the first study, water damage and visible moulds were reported in 7.4% and 17% of the homes respectively. The combination of water damage and visible moulds was independently associated with attacks of breathlessness when resting and after activity and also to long term cough. In the second study, the prevalence of nocturnal GER increased with higher BMI and the same pattern could be seen for habitual snoring. Reported onset of asthma, wheeze and night-time symptoms increased in prevalence along with the BMI gradient. In the multivariable analysis, obesity and nocturnal GER were independent risk factors for onset of asthma, wheeze and night-time symptoms. Habitual snoring was an independent risk factor for onset of wheeze and night-time symptoms, but not for onset of asthma. In the third study, a total of 18% of the subjects reported indoor dampness in the last 12 months and 27% of the subjects reported indoor dampness since the previous survey. Respiratory symptoms and asthma were significantly more prevalent in individuals exposed to indoor dampness and indoor dampness was a risk factor for respiratory symptoms and asthma after adjusting for possible confounders. Indoor dampness was an independent risk factor for onset of respiratory symptoms but not for asthma onset. Remission of respiratory symptoms was less likely to occur if subjects reported indoor dampness. In the fourth study, the lowest prevalence of atopy and the lowest levels of all indoor allergens, bacteria and moulds were found in Iceland. A positive association was found, between cat allergen exposure and asthma symptoms and between bronchial hyperresponsiveness and the amount of viable mould in indoor air.

Der volle Inhalt der QuelleObjetivos - Determinar a prevalência de asma brônquica em estudantes universitários portugueses; caracterizar a sua doença com base em sintomas auto reportados; identificar possíveis fatores de risco para a asma. Métodos – Neste estudo transversal observacional, uma amostra de 1000 alunos foi aleatoriamente selecionada para responder a um questionário de rastreio. O questionário foi entregue em papel, nas salas de aula, aos alunos identificados que deram o seu consentimento. Dos alunos identificados, 548 responderam ao questionário. Aqueles cujas respostas eram compatíveis com um provável diagnóstico de asma brônquica foram contactados, por via telefónica, com o objetivo de medir o controlo dos seus sintomas asmáticos no mês anterior. Para determinar potenciais fatores de risco de asma brônquica, foram efetuadas análises estatísticas multivariáveis, utilizando modelos de regressão logística. Resultados – Um total de 578 alunos respondeu ao questionário, e 121 alunos foram identificados com sintomas auto reportados compatíveis com o diagnóstico de asma brônquica. Desses, 48,8% já tinham sido diagnosticados como asmáticos por um médico, e 76% deles tinham também rinite. Os fatores desencadeantes de sintomas asmáticos mais identificados pelos estudantes foram corizas, exposição a pólenes, pó de casa, fumo de tabaco e variações climáticas. Dos estudantes identificados com sintomas compatíveis com o diagnóstico de asma, 50,4% atenderam a chamada telefónica, e, desses, 62,3% tinham sintomas asmáticos não controlados no mês anterior. Dos fatores de risco potencialmente associados a um aumento de risco de asma brônquica, constatou-se que dois aumentavam significativamente o risco de desenvolver asma: hábitos de tabagismo regular (OR = 2,09, 95% IC 1,21 a 3,62) e história pessoal de dermatite/ eczema atópico (OR 2,65, 95% IC 1,55 a 4,54). Conclusões – O valor de prevalência de asma brônquica nos estudantes universitários da Universidade da Beira Interior é de 20,9%. Destes, apenas 48,8% possuíam um diagnóstico prévio efetuado por um médico. Dos estudantes diagnosticados que nos permitiram medir o seu nível de controlo da asma, 62,3% não tinham os seus sintomas asmáticos controlados, podendo este facto estar relacionado com um irregular acompanhamento médico. Hábitos regulares de tabagismo e história pessoal de dermatite/eczema atópico aumentam significativamente o risco de asma brônquica.

Der volle Inhalt der QuelleAsthma in childhood seems affected by exposure to various factors in early life. To assess this hypothesis, we conducted 2 studies: one in France, and the other in Lebanon. In the French study, we aimed at describing wheezing phenotypes between the ages of two months and one year, and assess risk factors associated with these wheezing phenotypes in a large birth cohort. In the Lebanese study, the aims were to evaluate the associations between caregiver-reported use of medications, alcohol, cigarette and/or waterpipe (WP), and exposure to pesticides/detergents during pregnancy with childhood-onset asthma in Lebanon and to validate the Arabic version of the Asthma Control Test (ACT) among these children and identify risk factors that might affect asthma control.Methods: We studied 18,041 infants from the ELFE (French Longitudinal Study of Children) birth cohort. Parents reported wheezing and respiratory symptoms at two and 12 months, and answered a complete questionnaire (exposure during pregnancy, parental allergy).The study design of the Lebanese project consisted of a case-control study, conducted between December 2015 and April 2016, recruited 1503 children, aged between 3-16 years old. A questionnaire assessed the sociodemographic characteristics (age, gender, education level of both parents), the family history of asthma, and other known risk factors of asthma (heating system at home, child history of recurrent otitis, humidity in the house, child went to a daycare, smoking and drinking alcohol during pregnancy, exposure to pesticides and detergents).Results: Children with no symptoms (controls) accounted for 77.2%, 2.1% had had wheezing at two months but no wheezing at one year (intermittent wheezing), 2.4% had persistent wheezing, while 18.3% had incident wheezing at one year. Comparing persistent wheezing to controls showed that having one sibling (ORa=2.19) or 2 siblings (ORa=2.23) compared to none, nocturnal cough (OR=5.2), respiratory distress (OR=4.1) and excess bronchial secretions (OR=3.47) at two months, reflux in the child at 2 months (OR=1.55), maternal history of asthma (OR=1.46) and maternal smoking during pregnancy (OR=1.57) were significantly associated with persistent wheezing. These same factors, along with cutaneous rash in the child at 2 months (OR=1.13) and paternal history of asthma (OR=1.32) were significantly associated with increased odds of incident wheezing. Having one sibling (ORa=1.9) compared to none, nocturnal cough at 2 months (OR=1.76) and excess bronchial secretions at 2 months (OR=1.65) were significantly associated with persistent compared to intermittent wheezing.In the Lebanese study, the multivariate analysis showed that children living in North and South Lebanon and the children living in areas where pesticides are frequently used had an increased risk of asthma (ORa=1.625; ORa=13.65; ORa=3.307) respectively. Smoking WP during pregnancy and cigarette during lactation would increase the risk of asthma in children (ORa=6.11; ORa=3.44 respectively). A high Cronbach’s alpha was found for the full scale (0.959). As for the asthma control scale (ACT), the correlation factors between each item of the ACT scale and the whole scale ranged between 0.710 and 0.775 (p<0.001 for all items). Mother’s low educational level as well as the history of asthma in the mother and the father would significantly increase the risk of uncontrolled asthma (Beta= 1.862; Beta= 3.534; and Beta= 1.885 respectively). Cigarette smoking during breastfeeding and waterpipe smoking by the mother during pregnancy were both significantly associated with uncontrolled asthma (Beta= 2.105; Beta=2.325 respectively). Mother’s high educational level was significantly associated with more asthma control (Beta= -0.715)

Der volle Inhalt der QuelleContext - Regarding the natural history of occupational asthma (OA), there is increasing evidence that the inflammatory process leading to clinical asthma appears early after inception of exposure. The ABCD study (French acronym for early asthma in bakery and hairdressing) aims to answer two objectives: 1) describe the temporal evolution of the OA incidence in the early years of exposure of bakers/pastry-makers (BP) and hairdressers - occupations known at risk of OA - and 2) identify personal, occupational and nutritional risk factors. Method - The ABCD study has two intertwined facets: (i) a retrospective longitudinal cohort of past apprentices of increasing seniority allowing to estimate the early incidence of OA, and (ii) a nested case-control study allowing to explore some risk factors of OA. Results - 866 subjects participated to the study. The ABCD study shows a high cumulative incidence of OA during the first 4 years of exposure among BP, and in a lesser extent, among hairdressers. While the OA risk depends on atopic status for BP, it is positively associated, for hairdressers, with exposure intensity and, to a lesser extent, to body mass index and with a variety of nutritioal factors. Conclusions - This study produced original data on early incidence of OA. These data may provide support for the development of preventive action, in particular for the detection of OA in the early years of exposure
