<i>Artemisia</i> and <i>Ambrosia</i> hypersensitivity: co‐sensitization or co‐recognition?

Abstract

Patients showing both ragweed- and mugwort-positive SPT and/or RAST are co-sensitized. Future studies will establish whether IgE reactivity translates into clinical symptoms and, hence, if co-sensitized patients should undergo specific immunotherapy with extracts of both mugwort and ragweed pollen.
