Summary
Allergy to vine (Vitis vinifera) pollen is newly documented. Testing confirmed vine pollen causes allergic rhinoconjunctivitis and asthma in a sensitized patient.
Area of Science:
- Allergen immunotherapy
- Environmental allergy
- Clinical immunology
Background:
- Vine (Vitis vinifera) pollen allergy was previously undocumented.
- Vine pollen is produced in limited quantities during a brief May-June pollination period.
- This study investigates a case of suspected vine pollen allergy.
Observation:
- A patient presented with symptoms potentially linked to vine pollen exposure.
- Diagnostic methods included skin prick tests, specific IgE determination (CAP, RAST), and bronchial/conjunctival provocation tests.
- Control groups of healthy subjects and patients with other pollen allergies were included.
Findings:
- The patient exhibited positive skin prick test responses to Vitis vinifera pollen extract.
- Specific IgE testing confirmed sensitization to vine pollen (RAST class 2).
- Bronchial and conjunctival provocation tests elicited positive reactions to vine pollen extract.
Implications:
- Vine pollen (Vitis vinifera) can cause allergic sensitization.
- Exposure to vineyard plant pollen can lead to rhinoconjunctivitis and asthma.
- This finding expands the spectrum of known pollen allergens.
