Allergic bronchopulmonary aspergillosis (ABPA) is a condition characterised by an exaggerated response of the immune system (a hypersensitivity response) to . Aspergillosis is an infection caused by the fungus Aspergillus. Aspergillosis describes a large number of diseases involving both infection and growth of fungus.

When utilising high resolution CT scans, there can be better assessment of the distribution and pattern of bronchiectasis within the lungs, and hence this is the tool of choice in the radiological diagnosis of ABPA. Aspergillus spores are ubiquitous in soil and are commonly found in the sputum of healthy individuals. Only rarely does it appear in patients with no other identifiable pulmonary illness 5.

Allergic Bronchopulmonary Aspergillosis (ABPA)
ABPA should be suspected in patients with a predisposing lung disease —most commonly asthma or cystic fibrosis — and is often associated with chronic airway limitation CAL. Drug allergy Allergic conjunctivitis Latex allergy. Where present it is a strong diagnostic factor of ABPA and distinguishes symptoms from other causes of bronchiectasis. Log in Sign up. Hypersensitivity mechanisms, as described abovecontribute to progression of the disease over time and, when left untreated, result in extensive fibrosis of lung tissue.
Cystic Fibrosis Foundation Consensus Conference”. In people with predisposing lung diseases—such as persistent asthma or cystic fibrosis or rarer diseases such as chronic granulomatous disease or Hyper-IgE syndrome —several factors lead to an increased risk of ABPA. Aspergillosis describes a large number of diseases involving both infection and growth of fungus as well as allergic responses. They may expectorate orange-coloured mucous plugs.
Bronchocentric granulomatosis often occurs, which is characterised by necrotizing granulomatous inflammation that destroys the walls of small bronchi and bronchioles. Treatment consists of corticosteroids and antifungal medications.

ABPA often presents with shortness of breath, coughing and wheezing.
Graves’ disease Myasthenia gravis Pernicious anemia. Aspergillus fumigatus Figure 1: Newer triazole drugs—such as posaconazole or voriconazole —have not yet been studied in-depth through clinical trials in this context.
The Journal of Allergy and Clinical Immunology. From million asthma sufferers worldwide, ABPA prevalence in asthma is estimated between the extremes of 1. From Wikipedia, the free encyclopedia. These are likely underestimates of total prevalence, given the exclusion of CF patients and children from the study, as well as diagnostic testing being limited in less developed regions.
The Eastern Mediterranean region had the lowest estimated prevalence, with a predicted case burden of ,; collectively, the Americas had the highest predicted burden at 1, cases.

Inhaled steroids are ineffective. Aspergillus spores and hyphae can interact with ECM proteins, and it is hypothesised that this process facilitates the binding of spores to damaged respiratory sites. Proteases released by both the fungus and neutrophils induce further injury to the respiratory epithelium, leading to initiation of repair mechanisms such as influx of serum and extracellular matrix ECM proteins at the site of infection.
Despite this, there is evidence that acute-onset ABPA is improved by corticosteroid treatment as it reduces episodes of consolidation. The most common sites of infection are the respiratory apparatus lungs, sinuses and these infections can be: The hypersensitivity initially causes bronchospasm and bronchial wall edema, which is IgE-mediated.
Consolidation and mucoid impaction are the most commonly described radiological features described in ABPA literature, though much of the evidence for consolidation comes from before the development of computed tomography CT scans.

Itraconazole an antifungal drug has been shown to be of benefit when used in conjunction with steroids and longer term it may reduce the dosage of steroids required for ABPA treatment.

This entity is most commonly encountered in patients with longstanding asthmaand only occasionally in patients with cystic fibrosis 4,5. Clinics in Chest Medicine.

Some patients cough up brown-coloured plugs of mucus. There are challenges involved in long-term therapy with corticosteroids—which can induce severe immune dysfunction when used chronically, as well as metabolic disorders—and approaches have been developed to manage ABPA alongside potential adverse effects from corticosteroids. Brocopulmonar or Alternate Spellings: Oral, long-term, high-dose steroids are the usual method of management and the condition responds well to glucocorticoids.
