Sensitisation to Pollen Allergens in Children and Adolescents of Different Ancestry Born and Living in the Same Area.

Background: Allergy can start at early ages, with genetic and environmental factors contributing to its development.

Aim: The study aimed to describe the pattern of sensitisation and allergy in children and adolescents of Spanish versus Moroccan ancestry but born in the same rural area of Spain.

Methods: Participants were children and adolescents (3-19 years) of Spanish or Moroccan descent, born in Blanca, Murcia (Spain).

Subjects develop tolerance to Pru p 3 but respiratory allergy to Pru p 9: A large study group from a peach exposed population.

Peach tree allergens are present in fruit, pollen, branches, and leaves, and can induce systemic, respiratory, cutaneous, and gastrointestinal symptoms. We studied the capacity of peach fruit/Pru p 1, Pru p 3, Pru p 4, Pru p 7 and peach pollen/Pru p 9 for inducing symptoms following oral or respiratory exposure in a large group of subjects. We included 716 adults (aged 21 to 83 y.
