Summary
Latex glove allergy, affecting healthcare workers, is diagnosed using skin prick tests (SPT) and contact tests. SPT for latex is more reliable than serum IgE testing for identifying Type I allergies.
Area of Science:
- Occupational dermatology
- Immunology
- Allergology
Context:
- Healthcare workers frequently use latex gloves, leading to potential occupational allergies.
- Hand urticaria and dermatitis are common presentations in workers with suspected latex glove allergy.
Purpose:
- To investigate the prevalence and diagnostic methods for latex glove allergy in healthcare workers.
- To differentiate between Type I (immediate) and Type IV (delayed) hypersensitivity reactions to latex and other workplace allergens.
Summary:
- Skin prick tests (SPT) and contact tests were used to diagnose latex allergy in 20 healthcare workers. Type I latex allergy was confirmed in all 6 cases of contact urticaria. SPT with natural latex extract proved more valuable than serum-specific IgE. Type IV latex allergy was confirmed in 10 of 14 dermatitis cases.
- Four cases of dermatitis were attributed to antiseptic substances. Latex glove allergy was more prevalent in women. No familial allergy predisposition was noted, with only 4 patients having co-existing pollen and mite allergies. Additional contact allergies to metals and antiseptics were observed.
Impact:
- Highlights the diagnostic utility of SPT over serum IgE for Type I latex allergy.
- Identifies antiseptic substances as a cause of allergic contact dermatitis in healthcare workers.
- Suggests a higher incidence of latex glove allergy in women and the presence of multiple co-existing contact allergies.
