The data of the ISAAC project in Spain show a prevalence of childhood asthma ranging from 7.1% to 15.3%, with regional differences; a higher prevalence, 22.6% to 35.8%, is described for rhinitis, and atopic dermatitis is found in 4.1% to 7.6% of children. The prevalence of food allergy is 3%. All children in Spain have the right to be visited in the(More)
BACKGROUND Different opinion documents point to a patient age of under five years as a relative contraindication to specific immunotherapy, arguing that this age group has a greater risk of developing anaphylaxis, and that specially trained personnel are needed to deal with the problem if it occurs. However, insufficient evidence exists to support such an(More)
OBJECTIVE To develop and validate a questionnaire to assess asthma control in children (CAN). DESIGN Two versions of the CAN (for carers and children) were developed. Both versions were validated in an observational, prospective, multicenter study performed in 38 hospital outpatient clinics throughout Spain. Four hundred fifteen patients and their carers(More)
Patients who are allergic to latex (Hevea brasiliensis) may exhibit cross-hypersensitivity with foods. We present a case of anaphylaxis due to cassava in a patient suffering from pollinosis, latex allergy, and latex-fruit syndrome. We performed sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblotting with cassava, avocado,(More)
BACKGROUND The clinical efficacy of allergen immunotherapy using therapeutic vaccines containing modified allergen extracts has been previously shown. OBJECTIVE To evaluate the clinical efficacy of a vaccine containing depigmented, polymerized extract of Dermatophagoides pteronyssinus in asthmatic children, monosensitized to mites, after 4 months of(More)
Recurrent urticaria and recurrent angioedema are frequent adverse reactions in non-atopic patients who do not tolerate aspirin. Of 1,632 infants and children who visited our allergy department for the first time, nine children (0.55%), five males and four females, presented recurrent urticaria or recurrent angioedema after taking aspirin. No evidence of(More)
BACKGROUND Good control of allergic rhinitis (AR) in children is desirable because it is associated with diseases such as asthma. The aim of this analysis of the PETRA study was to characterise its diagnosis and treatment in Spanish children. METHODS Data were analysed for paediatric patients (age 5-17 years, inclusive) included in the PETRA study, which(More)
OBJECTIVE We present two adult and three paediatric patients who had allergic reactions after cheese ingestion and subsequently tolerated cow's milk derivatives. The objective of this study was to determine possible cross-reactivity between different types of cheese. METHODS Skin tests were performed to cow's milk fractions, and prick-prick tests for(More)
OBJECTIVE To assess the allergenic capacity of a new extensively hydrolysed casein formula (Damira 2000) in vivo in children with allergy to cow's milk, and to conduct an immunochemical evaluation of the product. PATIENTS AND METHODS The study comprised 67 children (1 month-7 years) with allergy to cow's milk proteins (ACMP). Skin testing was made with(More)
BACKGROUND AND OBJECTIVES The homologous group of sweet grasses belongs to the Pooideae subfamily, but grass pollen species from other subfamilies can also cause allergy, such as Cynodon dactylon (Chloridoideae) and Phragmites communis (Arundinoideae). C dactylon and P communis have not been included in the sweet grasses homologous group because of their(More)
