Method: The North West& North Wales Paediatric Allergy Network anonymised database was used to collate the information. Data was col-lected during a two-year period between April 2019 and March 2021.Results: Data on 5080 children, median age 5 (range 0–19) years old were available. Most children presented with classical immediate or delayed hypersensitivity reactions. 54% had an allergy to one food, 27% to two foods, 10% to three foods and 9% to four or more foods. 47 suffered from OAS, 13 FPIES, and 7 eosinophilic enteropathy. 35% had associated eczema and 25% asthma.
624 (12%) patients had one or more non “G8” food allergies. Legumes (35%), kiwi (19%), banana (6%), tomato (6%) and strawberry (5%) were most prominent. Children in Greater Manchester (42%) and Lancashire & Cumbria (43%) particularly those from Blackburn, Bolton, Oldham, Preston and Wigan, were significantly more likely to have a history of legume allergy than children in Cheshire & Mersey (28%) or North Wales (20%) (p < 0.001). There was a 3.4 (2.4 – 4.8)-fold higher risk of legume allergy in patients who had a peanut allergy. Legume allergy (OR 1.7), peanut allergy (3.5), asthma (3.7) and age (1.2) were all independently associated with a significantly increased risk of the child having an adrenaline auto-injector.
Conclusions: Allergies to legumes are prevalent, particularly in traditionally more multi-cultural areas of the North West. Children with these allergies are more likely to have an associated peanut allergy and carry an adrenaline auto-injector
