Allergic skin tests in Malaysian asthmatics

Area of Science:

• Allergy and Immunology
• Respiratory Medicine
• Clinical Research

Background:

• Asthma is a chronic respiratory condition affecting millions globally.
• Identifying specific allergens is crucial for effective asthma management.
• Skin prick testing is a common method for allergy diagnosis.

Purpose of the Study:

• To determine the prevalence of skin test sensitivity to common allergens in adult asthmatic patients in Malaysia.
• To compare allergy prevalence between asthmatic patients and healthy controls.
• To investigate the association between allergic rhinitis and skin test sensitivity in asthma.

Main Methods:

• A cross-sectional study involving 134 adult asthmatic patients and 120 control subjects in Malaysia.
• Standardized skin prick tests were performed to assess sensitivity to a range of common allergens.
• Data on associated rhinitis and demographic information were collected.

Main Results:

• A high prevalence of skin test sensitivity was found in asthmatic patients (90%) compared to controls (78%).
• House dust mite emerged as the most frequent allergen eliciting positive reactions in both groups.
• Sixty-four percent of asthmatic patients reported co-existing allergic rhinitis, with no significant difference in skin test sensitivity based on rhinitis status.

Conclusions:

• Skin test sensitivity to allergens is highly prevalent among adult asthmatic patients in Malaysia.
• House dust mites are a primary allergen contributing to allergic sensitization in this population.
• The presence of allergic rhinitis did not significantly alter skin test sensitivity patterns in asthmatic individuals.
