Risk FactorsThe risk of developing ABPA depends on the overall health and extends the exposure to the infestation. These factors may make more vulnerable to infection.
- Weakened Immune System.
- Low White Blood Cells [WBC] Levels.
- Asthma or Cystic Fibrosis.
- Lung Cavities.
Complications of Allergic Bronchopulmonary AspergillosisABPA can cause various serious complications, depending on the type of infections:
- Local emphysema
- Invasive aspergillosis
- Honeycomb fibrosis
- Chronic and recurrent lobar atelectasis
- Recurrent asthma exacerbations and steroid dependence
- Recurrent pulmonary infections and hemoptysis.
- Systematic infection.
Prevention of ABPAIt is nearly impossible to avoid exposure to Aspergillus, but the determined effort may yield some success. If you have had a transplant or are undergoing chemotherapy, try to avoid where you are likely to encounter aspergillus infection, such as construction sites, compost piles, and buildings that store grain. Avoid activities that are in close contact with dust soil. Always wear a face mask to avoid mold exposure if you know that you have a weakened immune system. Use of antifungal medications to prevent the disease.
Diagnosis of ABPAAspergillus is present in all environments but poses a significant challenge to distinguish from certain other fungi under the microscope. Diagnosing an aspergilloma or invasive aspergillosis can therefore be difficult. The symptoms of ABPA also resemble those of lung disorders, such as tuberculosis. To specify the cause of the symptoms, one or more of the following tests may be used:
- Aspergillus skin test.
- Imaging Test
- Sputum Test.
- Pulmonary Function Test.
- Tissue and Blood Tests.
Treatment for Allergic Bronchopulmonary AspergillosisABPA treatment varies with the type of disorder. The main aim of the treatment is to treat inflammation and reduce progressive lung injury. Possible treatments include the following:
- Oral Corticosteroids.
- Antifungal Medication.
- Antibiotics: To prevent or treat associated bacterial infections.
- Anti-IgE therapy 
The signs and symptoms of ABPA vary with the type of disease you develop. They include:
Some people with asthma or cystic fibrosis are allergic to aspergillus, and show the following signs:
- Cough with blood and mucus.
- Worsening previous asthma.
Some chronic lung conditions, like tuberculosis, emphysema, or advanced sarcoidosis, can develop air cavities in the lungs, and when such people are infected with aspergillus, fungus fibers may spread into the cavities and grow into tangled masses [fungus balls] known as aspergilloma.
Initially, aspergillomas may cause a mild cough, but over time and when left untreated, can worsen the underlying chronic lung condition and probably cause:
- Cough with blood [hemoptysis].
- Shortened breaths.
- Weight loss.
This is the most severe form of aspergillosis. It occurs when the infection extends rapidly from the lungs to the brain, heart, kidneys, or skin.
It happens only in people with a weakened immune system resulting from cancer chemotherapy, bone marrow transplantation, or a disease of the immune system. If untreated, invasive aspergillosis can be deadly. Its signs depend on affected organs. In general, it can cause:
- Shortened breaths.
- Chest pain.
- Joint pain.
- Eye problems.
- Skin lesions.
Other Types of Aspergillosis.
Apart from your lungs, aspergillus can invade other parts of your body [such as sinuses] and cause:
- Stuffy nose.
- Facial pains.
You can not avoid aspergillus. It is found everywhere, in decaying leaves and compost, on plants, trees, and other crops.
Most people have developed immunity to its effect, because of their healthy immune system. But to others with the weakened immune system from disease or immunosuppressant medications have fewer infections [fighting cells (white blood cells)]. Hence, aspergillus can invade the lungs and in the most severe cases, other parts of the body. It should, however, be noted that ABPA is not communicable from person to person.
1. Is ABPA life-threatening?
Allergic bronchopulmonary aspergillosis (ABPA) is a rare condition that may complicate asthma and cystic fibrosis. However, it is seldom seen as life-threatening.
2. Is ABPA curable?
There is no cure for ABPA. Treatment only refers to managing the condition, typically with corticosteroids taken orally or with puffers. Antifungal medication generally does not affect; it cannot penetrate the aspergillomas. People with ABPA should be monitored regularly to ensure their condition is successfully managed.
3. Is ABPA an automatic disease?
Allergic bronchopulmonary aspergillosis (ABPA) is a condition characterized by an immune system’s exaggerated response. A hypersensitivity response to the fungus, Aspergillus fumigates. It happens most often in individuals with asthma or cystic fibrosis.
4. How can you prevent ABPA?
To prevent aspergillosis:
- Try to avoid areas with much dust, like construction sites or evacuation sites.
- Avoid activities that involve close contact with soil or dust, such as building that store grain compost piles.
- Try to stay away from where you are likely to encounter aspergillosis infection.
- Always wear a face mask to avoid exposure to mold if you have a weakened immune system.
5. Is ABPA hereditary?
Cases of ABPA within families suggest common genetic bases with low penetrance. In one case series from India, 5% of cases were familial. However, more research is found in this area.
