“…25 Our results show that B. tropicalis Blo t 5 allergen was detected in a variety of foodstuffs sold in retail stores including wheat, corn, rice, beans, and processed foods (rusk, pasta, and pancakes). This result is contrary to that of Yi and others, 26 who suggested that the contamination of food with B. tropicalis depends on the presence of wheat in the food. However, our results are supported by other studies that reported mite contamination in corn flour, rice, and beans.…”

Abstract. The mite Blomia tropicalis has significant prevalence worldwide. Blo t 5 is a major B. tropicalis allergen that has been associated with sensitization and allergic symptoms in many asthmatic patients. Besides house dust, contaminated foodstuffs are an important source of exposure to B. tropicalis allergens. In this study, a double sandwich enzyme-linked immunosorbent assay (ELISA) using mAb 4D4 and biotinylated mAb 4G9 was done to detect Blo t 5 allergen in different types of raw and processed foods, including wheat, corn, rice, bean, wheat and corn flour, cake, and rusk, which were collected from retail stores in the Nile Delta of Egypt. Out of 88 samples, 38 (43.2%) were positive for Blo t 5 allergen with no significant statistical difference in positivity according to food type. In positive samples, the Blo t 5 concentration ranged from 10 ng/g to 790 ng/g. This study showed that Blo t 5 should be considered as an important allergen that presents a risk to the Egyptian population and should become a routine allergen in the skin prick test to improve the management of allergic disease.

Background: The study objective was to compare age-related differences in the cause and clinical presentation of anaphylaxis. Methods: We conducted a prospective study of patients visiting the emergency department for anaphylaxis. Data were collected from 3 emergency departments from 1 April 2014 to 31 December 2015. Patient electronic records with the diagnoses of allergy, angioedema, urticaria, and anaphylaxis (ICD-9 codes 9953, 9951, 7080, 9950, 7089) were screened and cases fulfilling World Allergy Organisation criteria for anaphylaxis were included. Results: A total of 426 cases of anaphylaxis were identified with a median age of 23 years (range 3 months to 88 years and 9 months). The causes of anaphylaxis were food (n = 236, 55%), drugs (n = 85, 20%), idiopathic (n = 64, 15%), and insect bites or stings (n = 28, 7%). The most common food was shellfish (n = 58, 14%) and the most common drugs were non-steroidal anti-inflammatory drugs (n = 26, 6%). There were more cases of food anaphylaxis in children than in adults (72 vs. 42%, p < 0.001) and more cases of drug anaphylaxis in adults than in children (28 vs. 10%, p < 0.001). Compared to patients of other ages, infants and young children had more gastrointestinal symptoms (adjusted odds ratio [aOR] 2.1, 95% CI 1.1-3.9), while schoolchildren and adolescents had more respiratory symptoms (aOR 2.7, 95% CI 1.4-5.2). Adults had more cardiovascular symptoms (aOR 2.9, 95% CI 1.8-4.6) and hypotension (aOR 3.7, 95% CI 2.1-6.8) compared to children. However, 42% of the infants lacked blood pressure measurements. Conclusions: Knowledge of age-related variation in the cause and clinical presentation of anaphylaxis aids in diagnosis and acute management.
