  1. 1. IgE sensitization against food allergens : Natural history, relation to airway inflammation and asthma

    Författare :Antonios Patelis; Andrei Malinovschi; Eva Rönmark; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allergen components; extract-based; exhaled NO; airway hyperresponsiveness; blood eosinophil count; IgE sensitization; food hypersensitivity; food allergens; perennial allergens; natural history; markers of systemic inflammation; markers of local inflammation; Lungmedicin; Lung Medicine; Fysiologi; Physiology; Immunologi; Immunology;

    Sammanfattning : Background: According to recent studies in children, IgE sensitization not only against perennial allergens, but also against food allergens, is related to asthma risk and increased airway inflammation. During the last decade, a new technique for IgE determination based on allergen components has become available, but its use in epidemiological studies has been limited. LÄS MER

  3. 2. Development of IgG subclass antibodies to allergens in early childhood

    Författare :Maria C. Jenmalm; Örjan Strannegård; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Background: Immune responses to allergens in young children include both Thl and Th2 like immunity, which may regulate the secretion of IgG subclass antibodies differently. The time, route and level of exposure to an allergen, as well as maternally transferred immunity, may be decisive whether sensitisation or tolerance will ensue. LÄS MER

  4. 3. Childhood asthma and indoor environment

    Författare :Aina M. Warner; Lennart Nordvall; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Background:During the last decades, the prevalence of asthma in childhood has increased in Sweden as well as in the rest of the western world. Some factor or factors in the indoor environment may be responsible for this. LÄS MER

  5. 4. Treatment of atopic asthma in primary health care guided by exhaled nitric oxide measurement

    Författare :Jörgen Syk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Aims: The overall aims of this thesis were to increase knowledge about how patients with asthma rate their health and investigate if we can improve asthma management, with focus on asthma as a chronic inflammatory disease, by use of measurement of the fraction of exhaled nitric oxide (FENO) in monitoring of asthma in primary health care. Methods: Study I included data from a public health questionnaire, which was sent to 8,200 persons (age > 18 years) randomly selected from the population register in Stockholm County. LÄS MER

  7. 5. Exhaled Nitric Oxide in epidemiological and experimental studies

    Författare :Anna-Carin Olin; Göteborgs universitet; []
    Nyckelord :Nitric oxide; exhaled air; nasal nitric oxide; ozone; pulp-mill; gassings; nitrate; ; atopy; sensitization; asthma; rhinitis; bronchiolitis;

    Sammanfattning : The overall purpose with this thesis has been to contribute to the assessment of theutility of exhaled nitric oxide (eNO) in epidemiological studies. The specific aims have been toinvestigate whether eNO increases after occupational exposure to high peaks of ozone, or afterexperimental exposure to ozone in ambient concentrations. LÄS MER
