[Allergic bronchopulmonary aspergillosis (ABPA)]

Area of Science:

• Medical Mycology
• Clinical Immunology
• Allergy Diagnostics

Context:

• Allergic bronchopulmonary aspergillosis (ABPA) is a common fungal allergy affecting the lungs.
• Current diagnostic criteria for ABPA vary across its five clinical stages, complicating accurate diagnosis.
• Distinguishing ABPA in remission from allergic asthma with Aspergillus sensitization is a significant challenge.

Purpose:

• To describe the potentials and limitations of current routine diagnostic procedures for ABPA.
• To highlight the need for early ABPA diagnosis to prevent progression to severe lung damage.
• To introduce advancements in diagnostic tools for more precise ABPA identification.

Summary:

• Traditional diagnostic methods for ABPA using crude allergen extracts suffer from variability, lack of standardization, and poor reproducibility.
• The development and evaluation of recombinant allergens from Aspergillus fumigatus represent a significant advancement.
• A panel of recombinant allergens is now available for routine use in diagnostic systems like CAP-System.

Impact:

• Improved early and precise diagnosis of ABPA, particularly in its early stages.
• Facilitates timely intervention to prevent irreversible lung damage and severe end-stage disease.
• Enhances diagnostic accuracy and reliability in clinical practice, moving beyond limitations of crude extracts.
