Alternaria sensitization often causes perennial asthma and other allergic symptoms, particularly in children. Skin prick tests are more reliable than RAST for diagnosing this fungal allergy.

Area of Science:

  • Allergy and Immunology
  • Environmental Health
  • Respiratory Medicine

Background:

  • Fungal spore sensitization frequently co-occurs with other allergies, complicating diagnosis.
  • Identifying specific fungal allergens is crucial for effective treatment.

Purpose of the Study:

  • To assess the prevalence, seasonality, and clinical characteristics of Alternaria monosensitization.
  • To understand the allergic profile of patients exclusively sensitized to Alternaria.

Main Methods:

  • Evaluated 37 subjects with confirmed Alternaria monosensitization (positive prick test).
  • Collected data on clinical symptoms, their timing, and immunological markers (RAST).

Main Results:

  • Over 50% of patients had asthma and other allergic symptoms.

  • 60% experienced perennial symptoms, indicating year-round exposure.
  • RAST results were positive in 11 of 34 subjects.

    • Conclusions:

    • Alternaria sensitization typically presents with year-round symptoms and severe respiratory issues like asthma, especially in pediatric populations.
    • Skin prick testing is recommended as a more reliable diagnostic method than RAST for Alternaria sensitization.
