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: Baculovirus expression system is one of the most attractive and powerful eukaryotic expression systems for the production of recombinant proteins. The presence of a biomarker is required to monitor transfection efficiency or protein expression levels in insect cells. Methods: The aim of this study was to construct a baculovirus expression vector encoding a copepod super green fluore...

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...

BACKGROUND Daily changes in aeroallergens during pregnancy could trigger early labor, but few investigations have evaluated this issue. This study aimed to investigate the association between exposure to aeroallergens during the week preceding birth and the risk of early delivery among preterm and term pregnancies. METHODS We identified data on 225,234 singleton births that occurred in six la...
