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.

Hypersensitivity mechanisms, as described abovecontribute to progression of the disease over time and, when left untreated, result in extensive fibrosis of lung tissue.

Synonyms or Alternate Spellings: 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. CT scans may more rarely reveal mosaic-appearance attenuationcentrilobular nodulestree-in-bud opacities and pleuropulmonary fibrosis a finding consistent with CPA, a disease with ABPA as a known precursor.

The symptoms are bdoncopulmonar to those of asthma: Another important feature is its ability to interact and integrate with epithelial surfaces, which results in massive pro-inflammatory counter-response by the immune system involving IL-6IL-8 and MCP-1 a CCL2 receptor ligand.

Aspergillosis describes a large number of diseases involving both infection and growth of fungus as well as allergic responses. The diagnosis can be made by chest X-ray along with sputum, skin and blood tests.

The Journal of Allergy and Clinical Immunology. Case 5 Case 5. 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. Therapeutic Advances in Respiratory Disease. As concentrations of Aspergillus proteases increase, the immunological effect switches from pro-inflammatory to inhibitory, and further reduces phagocytic ability to clear Aspergillus.

Therefore, it must be used in conjunction with other tests. Segmental and subsegmental bronchi are dilated and filled with mucous, admixed nroncopulmonar eosinophils and occasional fungal hyphae 4,7. The strongest evidence double-blinded, randomizedplacebo -controlled trials is for itraconazole twice daily for four months, which resulted in significant broncopulmoanr improvement compared to placebo, and was mirrored in CF patients.

Bronchocentric granulomatosis often occurs, which is characterised by necrotizing granulomatous inflammation that destroys the walls of small bronchi and bronchioles.

Aspergillus also utilises a number of factors to continue evading host responses, notably the use of proteolytic enzymes that interrupt IgG antibodies aimed towards it. Despite this, there is evidence that acute-onset ABPA is improved by corticosteroid treatment as it reduces episodes of consolidation.

Left untreated, the immune system and fungal spores can damage sensitive lung tissues and lead to scarring. The hypersensitivity initially causes bronchospasm and bronchial wall edema, which is IgE-mediated.

When no exacerbations from the disease are seen within three months after discontinuing corticosteroids, the patient is considered to be in complete remission.

The most common sites of infection are the respiratory apparatus lungs, sinuses and these infections can be:. Graves’ disease Myasthenia gravis Pernicious anemia. Cryptococcus neoformans Cryptococcosis Trichosporon spp Trichosporonosis.

Fungal infection and mesomycetozoea B35—B49— There are limited national broncopulomnar international studies into the burden of ABPA, made more difficult by a non-standardized diagnostic criteria. It occurs most often in people with asthma or cystic fibrosis. Coeliac disease Eosinophilic gastroenteritis Eosinophilic esophagitis Food allergy Egg allergy Milk intolerance. When serum IgE is normal and patients are not being treated by glucocorticoid medicationsABPA is excluded as the cause of symptoms.

These opacities usually appear and disappear in different areas of the lung over a period of time as transient pulmonary infiltrates. Both are more sensitive than conventional counterimmunoelectrophoresis.

There are hypersensitivity responses, both a type I response atopic, with formation of immunoglobulin E, or IgE and a type III hypersensitivity response with formation of immunoglobulin Gor IgG.
