CONTEXT Some studies have shown that inflammatory processes in the nasal air passages may reflect or affect those in the lower airways. We decided to indirectly assess the inflammatory status of the nasal airways in two groups of children with different sensitization rates to aeroallergens. OBJECTIVE To compare the inflammatory activity in the nasal airways, through the determination of media...

BACKGROUND Spores of many fungal species have been documented as important aeroallergens. Airborne fungal spores are commonly collected from the outdoor air at the rooftop level of high buildings; however, human exposure usually occurs nearer to the ground. It is necessary to estimate the concentration of airborne fungal spores at the human breathing level to evaluate the actual human exposure ...

OBJECTIVE Allergic rhinitis can determine the presence and type of asthma. The main aim of this study was to evaluate the link between allergic rhinitis, asthma, and skin test sensitization in patients with allergic rhinitis. METHODS Patients with allergic rhinitis, aged 10 to 50 years, were consecutively enrolled at different allergy centers in Spain and Portugal. All the patients underwent ...

BACKGROUND Recent studies have shown that systemic or respiratory occupational responses to latex can be induced by inhalation of latex aeroallergens. OBJECTIVE Our objectives were to study the relationship between exposure to different latex aeroallergen levels and type I allergic reactions in subjects with occupational contact with latex and to assess a threshold value for latex airborne al...

BACKGROUND Aeroallergens are the most common causes of allergy. AIM The aim of this study was to determine hypersensitivity to aeroallergens in patients with nasobronchial allergy. METHODS This retrospective population study included 2254 patients with nasobronchial allergy, from late adolescents to adults. Their response to aeroallergens was assessed by skin prick tests. RESULTS More pat...

OBJECTIVE To determine the pattern of skin prick test reactivity to aeroallergens in patients with asthma and rhinitis (airway allergy) residing in Riyadh region. METHODS This is a retrospective cross sectional study based on data analysis of skin prick test results of individuals with clinical diagnosis of airway allergy.Allergy skin prick test result data of 139 Saudi nationals from Riyadh ...

Climate change and its effects on aeroallergens and allergic disease have been extensively studied in the northern hemisphere, but there has been a dearth of similar studies in the southern hemisphere. Aeroallergens are extremely sensitive to certain weather parameters and changes may increase or decrease their levels in the atmosphere. Climate change projections include global warming, an incr...

BACKGROUND Atopic sensitization to aeroallergens in early life has been found to be a strong risk factor for the development of persisting asthma in young children with recurrent wheeze. OBJECTIVE To assess the yield of skin prick test (SPT) compared with allergen specific serum IgE (sIgE) testing at identifying aeroallergen sensitization in atopic children younger than 4 years. METHODS Con...
