Glasswort pollen allergy J30.- H10.1

Allergic reactions due to pollen of the glass herb (Parietaria judaica) s.a. herbal pollen allergy, which is mainly found in coastal areas of the Mediterranean. The major allergen Par j 2, a lipid transfer protein, is one of the most important allergens in the Mediterranean region.

FBisher known and identified pollen allergens of Parietaria judaica:

• Par j 1 phospholipid transfer protein
• Par j 2 lipid transfer protein (major allergen, indicator for allergies against other members of the LTP family; overlapping peptide chains have also been detected in Escherichia coli)
• Par j 3 Profilin
• Par j 4 Polcalcin

For allergy sufferers, glasswort is particularly important in the Mediterranean region. Here, sensitization against pollen of glasswort belongs to the most frequent events. In Central Europe, sensitization rates against Par j 2 are reported by 1% of pollinists. The plant blooms almost all year round, especially in June and September/November.
