A Component-resolved Diagnostic Approach for a Study on Grass Pollen Allergens in Chinese Southerners with Allergic Rhinitis and/or Asthma
Published on: June 4, 2017
Abstract:
IgE against the spices coriander and/or curry, mace, celery, and white pepper was measured in 150 sera from patients with suspected food allergies. Fifteen percent of the 288 spice RASTs resulted in greater than or equal to 10% binding of 125I-labeled anti-IgE. Twelve sera were studied in detail. In most sera IgE against various spices was present; all 12 sera contained IgE against mugwort-pollen extract. In RAST-inhibition experiments with three different sera, a cross-reactivity between mugwort pollen and coriander could be demonstrated. Leukocytes from two patients released histamine on incubation with spice extracts. This study suggests that IgE against various spices may play a role in some adverse reactions to food.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
