Summary
Cypress pollen causes hay fever in 24-32% of Israelis, with symptoms from February to April. Immunotherapy was successful for cypress-monosensitized patients.
Area of Science:
- Environmental Science
- Allergology
- Botany
Background:
- Cypresses (Cupressus sempervirens) are prevalent in Israel and the Mediterranean region.
- Cypress pollen is a significant allergen, with dispersal from January to April.
Purpose of the Study:
- To assess the prevalence of cypress pollen sensitization in hay fever patients in Israel.
- To evaluate the clinical symptoms and the effectiveness of immunotherapy in monosensitized individuals.
Main Methods:
- Patient surveys and clinical assessments.
- Analysis of sensitization to cypress pollen extracts.
- Evaluation of immunotherapy outcomes in monosensitized patients.
Main Results:
- 24%-32% of hay fever patients showed sensitization to cypress pollen.
- 13% of sensitized individuals were monosensitized to cypress.
- Symptoms included rhinitis (70%), asthma (30%), and conjunctivitis (18%) during the pollen season.
- Anti-cypress immunotherapy proved successful in monosensitized patients.
Conclusions:
- Cypress pollen is a major cause of allergic respiratory and ocular symptoms in Israel.
- Monosensitization to cypress pollen is common, and immunotherapy is an effective treatment option.
