Occupational asthma in a latex doll manufacturing plant

Area of Science:

• Occupational Medicine
• Allergology
• Respiratory Medicine

Background:

• Occupational asthma linked to natural rubber latex (NRL) is a known issue in healthcare and glove manufacturing.
• Previous reports have identified latex as an occupational sensitizer in various industries.

Purpose of the Study:

• To investigate occupational asthma in a novel setting: a latex doll manufacturing plant.
• To identify the risks and susceptible populations within this specific manufacturing environment.

Main Methods:

• Evaluated an index case with asthma symptoms through workplace challenge testing and environmental assessment.
• Conducted an occupational health survey and skin prick testing on 22 workers in the latex doll plant.
• Assessed worker responses to exposure to latex doll parts and common aeroallergens.

Main Results:

• The index patient experienced immediate bronchospasm during a workplace challenge involving sanding of latex.
• Two of 22 surveyed workers reported symptoms of flushing, rhinoconjunctivitis, and wheezing upon exposure to sanded doll parts.
• The symptomatic workers were the only ones with a history of atopy and positive skin test responses to latex and aeroallergens.

Conclusions:

• Sanding or grinding solid latex during manufacturing poses a significant risk for occupational asthma and rhinoconjunctivitis due to latex sensitization.
• Atopic workers demonstrate increased susceptibility to developing latex sensitivity in this occupational setting.
• This study highlights the latex doll manufacturing industry as a potential source of occupational latex allergy.
