[Occupational hypersensitivity to spiramycin. Report of a case]

Area of Science:

• Occupational Health
• Immunology
• Pharmacology

Background:

• Hypersensitivity reactions to antibiotics can pose significant risks in pharmaceutical manufacturing settings.
• Spiramycin, a macrolide antibiotic, is used in various therapeutic applications.

Observation:

• A 34-year-old female pharmaceutical worker handling Spiramycin powder developed occupational rhinoconjunctivitis and spasmodic cough.
• Symptoms appeared shortly after exposure and persisted after work, despite no prior history of atopy.
• Positive prick and intradermal tests confirmed Spiramycin hypersensitivity, further validated by nasal provocation tests.

Findings:

• The case demonstrates a clear link between occupational exposure to Spiramycin powder and the development of allergic respiratory symptoms.
• Diagnostic tests, including skin prick tests and nasal provocation, confirmed specific IgE-mediated hypersensitivity to Spiramycin.
• Immediate resolution of symptoms upon transfer to a different work section strongly supports an occupational allergy.

Implications:

• This case highlights the importance of recognizing and managing occupational hypersensitivity to antibiotics in pharmaceutical industry workers.
• Implementing stringent exposure controls and considering alternative work assignments are crucial for preventing recurrent allergic reactions.
• The findings underscore the potential for immunological mechanisms in adverse reactions to chemical products in the workplace.
