Latex-induced allergic rhinitis in a laboratory nurse

Area of Science:

• Allergy and Immunology
• Occupational Health
• Rhinology

Background:

• Occupational rhinitis is a common condition affecting healthcare workers.
• Natural rubber latex (NRL) hypersensitivity is a known occupational hazard, particularly for those with frequent glove use.
• Diagnosis typically involves a combination of clinical history, skin prick testing, and specific IgE measurement.

Observation:

• A nurse presented with symptoms suggestive of occupational rhinitis.
• Nasal provocation testing with NRL glove powder induced rhinorrhoea, increased nasal secretions, and mucosal edema.
• The patient exhibited a positive skin prick test to NRL allergens and elevated serum-specific IgE levels.

Findings:

• The case demonstrates a clear association between occupational rhinitis and NRL hypersensitivity in a healthcare setting.
• Nasal provocation testing effectively reproduced symptoms and objective changes, confirming the diagnosis.
• The findings are supported by positive immunological markers for NRL allergy.

Implications:

• This case underscores the importance of considering NRL hypersensitivity in healthcare workers with occupational rhinitis.
• It highlights the diagnostic utility of nasal provocation testing in such cases.
• Further research may be warranted to explore the prevalence and management of NRL-induced occupational rhinitis.
