Serum IgE antibodies against hazelnut in hazelnut processing workers

Area of Science:

• Occupational Health
• Allergology
• Immunology

Background:

• Previous research indicates elevated hazelnut sensitization among processing workers.
• A gap exists in understanding the link between workplace respiratory symptoms and hazelnut sensitization.

Purpose of the Study:

• To investigate the association between hazelnut sensitization and respiratory complaints in hazelnut processing workers.
• To assess the prevalence of specific IgE antibodies against hazelnut allergens in this cohort.

Main Methods:

• 88 hazelnut processing workers completed questionnaires on respiratory symptoms, smoking history, and allergies.
• Pulmonary function tests and serum IgE antibody measurements against hazelnut allergens were performed.

Main Results:

• 17.1% (14 out of 88) of workers tested positive for specific IgE against hazelnut allergens.
• No significant differences were observed in respiratory symptoms, allergy history, smoking status, or spirometry between sensitized and non-sensitized groups.

Conclusions:

• A notable percentage of hazelnut processing workers exhibit hazelnut sensitization.
• Sensitization to hazelnut allergens does not appear to correlate with work-related respiratory symptoms in this population.
• Further research into other potential respiratory health factors in hazelnut workers is warranted.
