Description

Aspergillosis is a fungal infection of the lungs caused by the genus Aspergillus, a common mould that is frequently breathed in from the environment, but most people are not affected. It most commonly affects people with lung diseases such as asthma, cystic fibrosis, or tuberculosis, as well as those who have had a stem cell or organ transplant, and those who are unable to fight infection due to medications such as steroids and some cancer treatments. It can occasionally cause skin problems.

Humans, birds, and other animals are all susceptible to aspergillosis. Aspergillosis can be chronic or acute, with distinct clinical manifestations. The majority of cases of acute aspergillosis occur in people whose immune systems are severely compromised, such as that undergoing bone marrow transplantation. Chronic colonization or infection can exacerbate respiratory illnesses such as asthma, cystic fibrosis, sarcoidosis, tuberculosis, or chronic obstructive pulmonary disease. Aspergillosis most commonly manifests as Chronic Pulmonary Aspergillosis (CPA), aspergilloma, or Allergic Broncho Pulmonary Aspergillosis (ABPA). Some types are related; for example, ABPA and simple aspergilloma can both progress to CPA.

Diagnosis

Diagnosis of an aspergilloma or invasive aspergillosis can be challenging. Under the microscope, Aspergillus is common in all environments but difficult to distinguish from other moulds. Aspergillosis symptoms are also similar to those of other lung diseases such as tuberculosis.

Imaging test

A chest X-ray or Computerized Tomography (CT) scan a type of X-ray that produces more detailed images than traditional X-rays can usually reveal a fungal mass (aspergilloma), as well as invasive aspergillosis and allergic broncho-pulmonary aspergillosis.

Respiratory secretion (sputum) test

A sample of sputum is stained with a dye and checked for the presence of aspergillus filaments in this test. The specimen is then placed in a culture that promotes mould growth in order to confirm the diagnosis.

Tissue and blood tests

Skin, sputum, and blood tests may all be useful in confirming allergic broncho-pulmonary aspergillosis. A small amount of aspergillus antigen is injected into the skin of the forearm for the skin test. If the blood contains mould antibodies, it will form a hard, red bump at the injection site. Blood tests look for high levels of specific antibodies, which indicate an allergic reaction.

Biopsy

Under a microscope, a sample of tissue from the lungs or sinuses may be required in some cases to confirm a diagnosis of invasive aspergillosis.

Treatment

Oral corticosteroids

The goal of treating allergic broncho-pulmonary aspergillosis is to prevent the worsening of existing asthma or cystic fibrosis. Oral corticosteroids are the most effective way to accomplish this. Antifungal medications alone aren't effective for allergic broncho-pulmonary aspergillosis, but they can be combined with corticosteroids to lower the dose of steroids and improve lung function.

Surgery

When aspergillosis is present and causing serious problems, such as excessive bleeding, surgery may be required. Because antifungal medications are usually ineffective against aspergillosis, surgery is advised. Embolization may be an option for obstructing blood flow to the artery supplying blood to the lung cavity, which is where the fungus ball is located. This will stop the bleeding, but it may happen again later.

Prevention

It is extremely difficult to avoid exposure due to the prevalence of aspergillus mould in the environment. It is best to avoid places where there is a lot of dust or mould, such as construction sites or compost piles. People with compromised immune systems or mould allergies should avoid gardening and lawn mowing. Consider wearing a face mask or N95 mask if exposure to airborne dust.
