1. Allergen-Specific Immunotherapy in Patients 55 Years and Older: Results and Review of Literature
Introduction Over the years the immune system suffers many morphologic and functional alterations, which result in a peak of function in puberty and a gradual decrease in the elderly. Aim Treat patients 55 years or older with allergic rhinitis with immunotherapy and then analyze the response to allergens. Materials and Methods From June 2009 to

2. The hammock: a reservoir of allergens
INTRODUCTION: Asthma affects approximately 10% of the world's population. Sensitization to allergens is an important risk factor, and exposure to allergens is associated with disease severity. METHODS: We performed skin tests to evaluate allergen sensitization to mites, cockroaches, cats, dogs, and molds in 73 asthmatic patients. Enzyme Linked Immunosorbent

3. Exposição a alérgenos de poeira doméstica e sua associação com atopia e asma em crianças entre 4 e 12 anos de idade em Salvador, Bahia. / Exposure to house dust allergens and their association with atopy and asthma in children between 4 and 12 years-old in Salvador, Bahia.
Introdução: Os alérgenos de poeira domiciliar são considerados fatores de risco para o aumento na prevalência e incidência das doenças alérgicas, observado nos últimos 30 a 40 anos. Alguns estudos mostram uma relação dose-resposta entre exposição a estes alérgenos e ocorrência de sensibilização e desencadeamento de sintomas alérgicos. Objet

4. Prevalence of mites in dust samples from mattress surfaces from single beds or cribs and evaluation of the home environment and sensitivity to mites in atopic patients residing in the south Brazilian city of Londrina / Avaliação do ambiente domiciliar e da sensibilidade cutanea imediata de pacientes atopicos e a prevalencia de acaros em amostras de poeira coletadas de colchões de camas e berços na cidade de Londrina-PR
The prevention and treatment of symptoms related to asthma and allergic rhinitis must include the environmental control of aeroallergens such as mites and cockroaches. The aim of this study was to investigate mites in mattress dust samples from cribs or beds in the southern Brazilian city of Londrina, State of Paraná as well as to evaluate the possible inte

5. Effect of salbutamol on pulmonary responsiveness in chronic pulmonary allergic inflammation in guinea pigs
Beta-2-agonists have been widely used by asthmatic subjects to relieve their obstructive symptoms. However, there are reports that continuous use could lead to loss of bronchial protection and exacerbation of asthma symptoms. We evaluated the effect of two regimens of salbutamol administration (twice and five times a week) in a model of chronic airway inflam

6. Níveis de alérgenos inaláveis em veículos utilitários de transporte escolar em Uberlândia, MG
The allergen exposure is considered crucial for the development of allergies. The aim of this study was to measure mite (Der p 1 and Der f 1), dog (Can f 1) and cat (Fel d 1) allergens, in school transport vehicles. It was analized 163 seat dust samples from 60 vehicles, using ELISA tests. The Can f 1 allergen was the most frequent (geometric mean = 1.03 g/g

8. Airway response of asthmatic subjects to inhaled allergen after exposure to pollutants.
BACKGROUND: Recent studies have suggested that air pollutants resulting from vehicle exhaust emissions and burning of fossil fuels, either in combination or individually, may enhance the airway response of asthmatic subjects to inhaled allergen. It was hypothesised that the airway response to inhaled allergen after exposure to a combination of 400 ppb nitrog

9. Environmental tobacco smoke exposure does not prevent corticosteroids reducing inflammation, remodeling, and airway hyperreactivity in mice exposed to allergen
The ability of corticosteroids to reduce airway inflammation and improve lung function is significantly reduced in asthmatics who are tobacco smokers compared with asthmatics who are nonsmokers. As not only high levels of tobacco smoke exposure in active smokers, but also significantly lower levels of tobacco smoke exposure from passive environmental tobacco

10. Balance between early life tolerance and sensitization in allergy: dependence on the timing and intensity of prenatal and postnatal allergen exposure of the mother
Allergens can be maternally transferred to the fetus or neonate, though it is uncertain how this initial allergen exposure may impact the development of allergy responses. To evaluate the roles of timing and level of maternal allergen exposure in the early life sensitization of progeny, female BALB/c mice were given ovalbumin (OVA) orally during pregnancy, l

11. Effect of natural allergen exposure during the grass pollen season on airways inflammatory cells and asthma symptoms.
BACKGROUND: Bronchial challenge with allergen causes a specific form of airways inflammation consisting of an influx of neutrophils, eosinophils, and T cells. Because the relevance of the challenge model to clinical asthma is uncertain, the cellular changes that occur in the lungs of asthmatic subjects during natural seasonal allergen exposure were investiga

12. An etiological role for aeroallergens and eosinophils in experimental esophagitis
Eosinophil infiltration into the esophagus is observed in diverse diseases including gastroesophageal reflux and allergic gastroenteritis, but the processes involved are largely unknown. We now report an original model of experimental esophagitis induced by exposure of mice to respiratory allergen. Allergen-challenged mice develop marked levels of esophageal
