D1.54 - Latex-Induced Occupational Asthma: An Underrecognized Hazard in the Electronics and Cable Industry

Background: Latex is a well-known occupational allergen in healthcare and rubber industries, but it is rarely considered in electronics and cable manufacturing. This study aimed to report a case of occupational allergic asthma caused by latex in a worker employed in cable assembly.

Results: A 39-year-old female operator working since 2014 in a company producing industrial and electrical connectivity components, including couplings, connectors, and cable assemblies, developed work-related respiratory symptoms. Her tasks included operating a cable-contacting machine, assembling cables according to schematic diagrams, and snapping cables into place. Occupational exposures involved rubber in cable sheaths and metals. Nine years after her employment, she started experiencing tearing, dry cough, paroxysmal episodes of dyspnea and sometimes episodes of eyelid edema. These symptoms occurred on workdays and markedly improved on leaves. Physical examination revealed no notable findings. Spirometry with bronchodilator reversibility testing showed a mild reversible obstructive ventilatory disorder. Specific IgE testing for latex was positive, confirming sensitization. Based on the temporal relationship with work, clinical features, and sensitization to latex, a diagnosis of occupational allergic asthma due to latex exposure was established. Latex proteins were identified as the causative agent present in rubber sheaths of cables. Asthma was considered a compensable occupational disease. The patient underwent job reassignment to eliminate exposure to latex.

Conclusions: Occupational allergic asthma due to latex can occur in unexpected industries, such as cable and electronics manufacturing. Recognition of latex as a potential allergen in this context is essential for timely diagnosis and prevention.
