Abstract:
1428 patients with respiratory conditions (rhinitis, asthma, rhinitis in association with asthma) were studied, 296 patients (20.72%) producing positive skin reaction to moulds either in isolation or in association. Of the 296, 29.95% of subjects with rhinitis, 38.74% of the asthmatics and 31.26% with rhinitis and asthma were sensitive to moulds. The onset of allergic symptoms occurs most frequently in 20-30 year olds. Most patients were permanently affected. The Mucoraceae were the phycomycetes most frequently producing an allergic reaction.
Insights
Moulds trigger allergic reactions in over 20% of patients with respiratory conditions like asthma and rhinitis. Mucoraceae fungi are the most common culprits, with symptoms often appearing in young adults.
Area of Science:
- Allergen immunotherapy
- Environmental microbiology
- Pulmonary medicine
Context:
- Respiratory conditions such as rhinitis and asthma are prevalent globally.
- Identifying specific allergens is crucial for effective patient management.
- Moulds are common environmental triggers for allergic respiratory diseases.
Purpose:
- To investigate the prevalence of mould allergy in patients with respiratory conditions.
- To identify specific types of moulds responsible for allergic reactions.
- To understand the demographic distribution and chronicity of mould-induced allergies.
Summary:
- A study of 1428 patients with respiratory conditions found 20.72% had positive skin reactions to moulds.
- Among mould-sensitive patients, prevalence was highest in asthmatics (38.74%).
- Mucoraceae were identified as the most frequent cause of allergic reactions, with symptoms often persistent and onset in young adults (20-30 years).
Impact:
- Highlights the significant role of moulds as allergens in respiratory diseases.
- Provides data for targeted diagnostic and therapeutic strategies for mould allergies.
- Informs public health initiatives regarding environmental mould exposure and respiratory health.
