[Multicenter study on sensitization to Alternaria mold]
1Commission Nationale d'Etudes et de Recherches en Allergologie Rurale (CNERAR), Quimperlé.
Abstract:
The reality emerged of a non-negligible frequency of positive tests to "Alternaria". This was conducted by the inclusion of this mould in the standard allergy assessment, especially if a summer predominance of symptoms was known. A significant difference emerged between seasonal peaks which had to do with mono or polysensitisation. The highest frequency of positives was found near to humid surroundings or woods.
Insights
Alternaria mold is frequently detected in allergy tests, particularly in summer. Higher positive test rates were observed near humid environments and woods, distinguishing between seasonal allergy patterns.
Area of Science:
- Environmental science
- Allergology
- Mycology
Context:
- Allergy assessment protocols
- Prevalence of mold sensitization
- Environmental risk factors for allergies
Purpose:
- Evaluate the frequency of Alternaria sensitization
- Correlate positive Alternaria tests with environmental factors
- Analyze seasonal patterns in allergic responses
Summary:
- A notable frequency of positive Alternaria tests was identified.
- Inclusion of Alternaria in standard allergy assessments is recommended, especially for summer symptom predominance.
- Higher positive test rates were associated with proximity to humid areas or woodlands.
- Distinct seasonal peaks were observed, differentiating between mono- and polysensitization.
Impact:
- Informs clinical practice for diagnosing mold allergies
- Highlights environmental triggers for allergic diseases
- Improves understanding of mold sensitization patterns
