ABPA is a hypersensitivity lung disorder, an exaggerated immune response to the colonization of the airways by the common fungus Aspergillus fumigatus. It almost exclusively affects individuals with asthma or cystic fibrosis.

The "profile" refers to the combination of findings needed to meet the diagnostic criteria.

🔬 Key Components of an ABPA Profile
The diagnosis of ABPA typically requires a combination of clinical symptoms, radiological findings, and specific blood tests, often encompassed in the "ABPA profile."

Clinical and Radiological Criteria
These lab tests are interpreted in the context of the patient's condition and imaging results:

Predisposing Condition: Asthma or Cystic Fibrosis.

Clinical Symptoms: Worsening or uncontrolled asthma, recurrent wheezing, productive cough (sometimes with brownish mucus plugs or blood-stained sputum), and shortness of breath.

Radiological Findings (Chest X-ray or HRCT Scan):

Fleeting pulmonary infiltrates (shadows that appear and disappear).

Central Bronchiectasis: Abnormal, permanent dilation of the central airways (a key, often pathognomonic, finding).

Mucoid Impaction (Bronchocele): Thick mucus plugging the dilated airways, sometimes appearing as the "finger-in-glove" sign.
