Insights
Parietaria Judaica pollen allergy affects patients with asthma and rhinitis. Polysensitive patients showed higher IgE levels, while monosensitive patients experienced more characteristic rhinitis and asthma symptoms.
Area of Science:
- Allergy and Immunology
- Respiratory Medicine
Background:
- Pollen allergies, including Parietaria Judaica, are significant contributors to respiratory conditions.
- Understanding patient sensitization patterns is crucial for effective allergy management.
Purpose of the Study:
- To analyze the clinical presentation and sensitization profiles of patients with Parietaria Judaica allergy.
- To investigate the relationship between sensitization patterns (monosensitive vs. polysensitive) and allergic symptoms.
Main Methods:
- Selection of 183 patients diagnosed with asthma, rhinitis, and/or conjunctivitis.
- Performance of skin prick tests for Parietaria Judaica.
- Categorization of patients into monosensitive and polysensitive groups based on test results.
- Follow-up testing and clinical symptom assessment.
Main Results:
- Out of 183 patients, initial testing showed 91 positive responders (11 monosensitive, 80 polysensitive); follow-up revealed 92 positive responders (5 monosensitive, 87 polysensitive).
- Rhinitis preceded asthma in 23 of 54 rhinitis cases, and asthma co-occurred with rhinitis in 90 of 129 asthma cases.
- Polysensitive patients exhibited higher IgE levels upon re-examination.
- Monosensitive patients predominantly presented with rhinitis syndrome (16.89%) and asthma with rhinitis (49.18%).
- Parietaria Judaica allergy showed seasonal peaks in Spring and Autumn, with reduced activity in Winter and 18.57% perennial cases.
Conclusions:
- Parietaria Judaica allergy is associated with a high prevalence of both rhinitis and asthma.
- Polysensitivity to allergens correlates with elevated IgE levels.
- Monosensitivity to Parietaria Judaica is linked to specific clinical manifestations of rhinitis and asthma with rhinitis.
Abstract:
We selected 183 patients with asthma, rhinitis and/or conjunctivitis. They responded positively to Parietaria Judaica skin prick-tests. In the first test 91 were positive. Of those 11 were monosensitive and 80 polysensitive. In the follow-up tests 92 were positive, of which 5 were monosensitive and 87 polysensitive. There were 54 cases of rhinitis, of which 23 developed asthma. Of 129 asthma cases, 90 developed asthma with rhinitis. The main seasons are Spring and Autumn and activity declines during winter. 18.57% are perennial. IgE was greater in the re-examination of the polysensitive cases. The monosensative cases confirmed the clinical symptoms most characteristic of rhinitis syndrome, 16.893% and asthma with rhinitis, 49.18%.
