Background In the event that a food-allergen was presumed as a likely accused of signs/symptoms, after that, the substantiation of major associations and finally, identifying the incriminated food(s) need to be warranted. As for verifying of an IgE-mediated food allergy, different specific mensurations should be accomplished in order to include/exclude the suspected food(s). One protocol for me...

Methods Thirty-five children (median age: 8.3, range2.2–14.2 yr) reported with immediate reactions to hazelnut ingestion underwent food challenge (DBPCFC) between April 2007 and May 2012. Skin prick test (SPT), specific IgE determination at ImmunoCAP with whole food allergens and with allergen components at ImmunoCAP ISAC microarray chip were performed. The molecular profile of reactivity was c...

Background In Canada, Omalizumab is indicated for adults and adolescents with moderate to severe persistent allergic asthma, but not for pediatric use (<12 years of age). A 9 year-old boy with steroid dependent, allergic asthma, multiple ICU admissions and severe back pain from compression fractures was referred to our centre. IgE was 1337 IU/ml. Skin prick testing showed multiple positive reac...

A 55-yr old female worker in a tea-packing production line developed asthma to tea-dust. She had no previous history of chest disease, and skin prick testing to a solution of tea-dust and to a variety of common allergens were all negative. Diagnosis was established by serial peak expiratory flow rate readings. Bronchial provocation challenge with tea-dust demonstrated a late asthmatic reaction.

Price, J. F., Cogsweil, J. J., Joseph, M. C., and Cochrane, G. M. (1976). Archives ofDisease in Childhood, 51, 912. Exercise-induced bronchoconstriction, skin sensitivity, and serum IgE in children with eczema. Forty-two children with eczema were studied for exercise-induced asthma (EIA), skin sensitivity to prick testing, blood eosinophil count, and immunoglobulins. 29 had a fall in peak expir...

hours of cow’s milk ingestion, skin prick tests $3 mm, and serum specific IgE levels $0.35 kU/L for whole cow’s milk, casein, a-lactalbumin, or b-lactoglobulin. Persistence of CMP allergy in the 4 weeks before tolerance induction was based on positive skin and serum testing and a positive double-blind placebo-controlled food challenge to cow’s milk. Exclusion criteria included anaphylactic shoc...

Methods A prospective 10-year-follow-up study has been designed to evaluate 194 LAR patients and 97 healthy controls. All LAR patients had positive response to nasal allergen provocation test (NAPT) with at least one aeroallergen. Demographic and clinical questionnaire, spirometry, skin prick testing, and serum specific IgE antibodies to common aeroallergens were evaluated yearly, and NAPT were...

peripheral blood eosinophil count, skin prick tests, and IgE testing. Infants’ microbiota were assessed through collection of fecal samples at 1 and 12 months of life. Polymerase chain reaction fragments from infant stool separated by DGGE (denaturing gradient gel electrophoresis) provided relative assessment of main bacterial strains and were used in assessing variety and richness in microbial...
