Specific immunotherapy could prevent elementary-school children who are sensitised to pollen and who have a history of hay fever from developing asthma.
While such children appear to be at considerable risk of developing pollen asthma, they are not diagnosed quickly, German researchers suggest. Specific immunotherapy might be a means of preventing asthma completely in such a situation.
Investigators from University Children’s Hospital in Freiburg, Germany, conducted a longitudinal cohort study of children age eight-to-10 years old over four years in six rural towns in Baden-Wurttemberg. They surveyed the children each spring and autumn, recording hay fever complaints, asthma-defining symptoms and new medical diagnoses of both hay fever and asthma. They performed skin prick tests with pollen allergens every autumn.
