Occurrence/EpidemiologyThis section has been translated automatically.
Preferably women are affected. Occupationally caused primrose allergy among florists and gardeners is still reported in individual cases.
The sensitization rates were in different countries. Collectives with routine testing of Primin between 0,3 - 1,0% . In a Danish study from 1984 to 1989 the sensitisation rate was 1.8% (57 out of 3075).
In a larger (Italian) collective of patients with potential contact sensitization (n=24,000), Bongiorni L et al. (2015) were able to demonstrate a Primin sensitization rate of 1.9%, with women (2.6%) being sensitized more often than men (0.5%). In certain areas of Italy (Pordonne) even higher sebisbilisation rates (up to 6%) were detected.
Cross-reactions with structurally similar quinones found in other plants or wood species, e.g. Dalbergia species, teak (Tectona grandis) or Pao ferro (Macherium skleroxylon) are possible, but are rarely observed.

EtiopathogenesisThis section has been translated automatically.
Primin is one of the strongest known allergens. It was therefore often used as a model substance for studying allergic reactions in humans. Sensitization is achieved by contact with the glandular hair secretion of Primula obonica (poison primrose, cup primrose). The allergenic effect depends on the content of primine.
Remark: The medically used primula species contain almost no primin (see below primrose = primula veris).

The epicutaneous test is recommended with synthetic primin in vaseline at a concentration of 0.01%.
