Solution

Based on the given information, we can deduce that the patient's allergy symptoms are reduced when she takes an antihistamine. This suggests that the symptoms are caused by the release of histamine, which is typically released by basophils and mast cells.

Histamine release is often associated with an immune response mediated by a specific type of leukocyte called eosinophils. Eosinophils are known to be involved in allergic reactions and can contribute to the severity and persistence of allergy symptoms.

Therefore, before the treatment with the antihistamine, it is likely that the patient had increased activity of eosinophils, which could have been responsible for her severe and persistent allergy symptoms.
