Sunflower (Helianthus annuus) Seed Allergy

Area of Science:

• Allergy and Immunology
• Food Science
• Clinical Medicine

Background:

• Sunflower seed consumption is increasing globally.
• Sunflower seed allergy has been documented since the 1970s.
• Limited data exist on sunflower seed allergy prevalence and clinical features.

Purpose of the Study:

• To investigate the clinical and immunological characteristics of sunflower seed allergy.
• To enhance understanding of sunflower seed allergy manifestations and management.

Main Methods:

• Retrospective analysis of 47 patients diagnosed with sunflower seed allergy.
• Evaluation of clinical history, skin prick tests, and specific IgE levels.
• Assessment of reaction severity and management strategies.

Main Results:

• Most sunflower seed allergies were adult-onset, often linked to other food allergies.
• Reactions varied from mild to severe anaphylaxis, with underuse of epinephrine.
• Sunflower seed-specific IgE correlated with IgE for lipid transfer proteins.

Conclusions:

• Sunflower seed allergy presents with variable clinical outcomes, even with repeated exposures.
• Epinephrine underuse in anaphylaxis is a significant concern.
• Strict avoidance and appropriate epinephrine prescription are vital for patient safety.
