Summary

Floral workers experience high rates of hand dermatitis. Alstroemeria, a popular flower, may cause allergic reactions, with tuliposide A identified as a potential allergen in patch tests.

Area of Science:

  • Dermatology
  • Occupational Health
  • Allergology

Background:

  • Hand dermatitis is increasingly prevalent among floral shop workers in the United States.
  • The popularity of Alstroemeria since 1981 has raised concerns about its potential role in causing dermatitis.
  • Previous studies have not fully investigated the specific causes of hand dermatitis in this occupational group.

Purpose of the Study:

  • To investigate the prevalence of hand dermatitis in floral workers.
  • To identify potential plant-related allergens causing hand dermatitis in this population.
  • To assess the association between Alstroemeria exposure and allergic contact dermatitis.

Main Methods:

  • A survey was conducted among 57 floral workers to determine the incidence of hand dermatitis.
  • Patch testing was performed on 16 floral workers (8 with dermatitis) using standard allergens, pesticides, and plant extracts.
  • Specific focus was placed on testing with Alstroemeria allergens, particularly tuliposide A.

Main Results:

  • Twenty-six percent (15 out of 57) of floral workers reported experiencing hand dermatitis within the past year.
  • Three out of four floral designers with dermatitis showed positive patch test reactions to tuliposide A, the identified allergen in Alstroemeria.
  • No other plant extracts elicited positive patch test reactions; one pesticide, difolatan (Captafol), showed a positive reaction of unknown relevance.

Conclusions:

  • Alstroemeria, specifically tuliposide A, is a significant potential cause of allergic contact hand dermatitis in floral workers.
  • Occupational exposure to Alstroemeria poses a risk for developing hand dermatitis in susceptible individuals.
  • Further investigation is warranted to understand the role of pesticides like difolatan in occupational dermatitis.
