Pulmonary alveolar proteinosis (PAP) is a rare and serious lung disease which was first identified in 1958. This condition is characterised by the accumulation of a protein-rich substance in the alveoli, the tiny air sacs in the lungs where oxygen exchange occurs. This buildup interferes with normal lung function, leading to impaired oxygen absorption and difficulty in breathing.

What is Pulmonary Alveolar Proteinosis?

The term "pulmonary" refers to anything related to the lungs. Pulmonary alveolar proteinosis (PAP) is a disease characterised by the buildup of a protein substance in the air sacs (alveoli) of the lungs, making breathing difficult.

Idiopathic pulmonary alveolar proteinosis (I-PAP) is an extremely rare disease of unknown aetiology. In this, the alveoli are filled with lipo proteinaceous material. It is an autoimmune disease with a neutralising antibody of the immunoglobulin G isotype. This antibody is against the granulocyte/macrophage colony-stimulating factor (GM-CSF).

Chances of Pulmonary Alveolar Proteinosis

Pulmonary Alveolar Proteinosis (PAP) is a rare lung disease with very low chances of occurrence. It's not fully clear why it happens, but it can affect people of any age. Some cases are linked to genetic or autoimmune conditions. If you have symptoms like a persistent cough, trouble breathing, or unusual chest X-rays, see a doctor for diagnosis and treatment.

How is Pulmonary Alveolar Proteinosis Detected?

Healthy people can have low levels of GM-CSF autoantibodies. However, if the level of these antibodies is above 5 μg/mL, the risk of developing pulmonary alveolar proteinosis increases. The latex agglutination test is commonly used to check for these antibodies.

Routine blood tests are usually done to detect this disease. A diagnosis of PAP is typically supported by results from a chest X-ray or computed tomography (CT scan). These tests generally reveal extensive white patches within the lungs (ground glass opacity) with superimposed angular lines (reticular densities).

The following are the main features that characterise the appearance of pulmonary alveolar proteinosis on High-resolution computed tomography (HRCT):

Smooth thickening of interlobular
Intralobular septal lines
Ground glass opacities

Additional Tests for PAP May Include:

Bronchoscopy to look into your airways.
Blood tests to analyse your blood oxygen levels.
Pulmonary function testing to measure lung functioning.
A lung biopsy is used to remove tissue from your lungs for examination.
A serum biomarker called GM-CSF autoantibody defines the cause of PAP.

Symptoms of Pulmonary Alveolar Proteinosis

The following are the symptoms of PAP:

Fever
Fatigue
Chest pain
Weight loss
Lung infections
Clubbed fingers
Shortness of breath
Fever, if there is a lung infection
Cyanosis (bluish skin and fingernails)
Cough, sometimes with blood or phlegm

Causes of Pulmonary Alveolar Proteinosis

The cause of PAP is relatively unknown in some cases. In others, it happens with a general lung infection or an immune problem. It can also occur with cancers of the blood system and after a person gets exposed to high environmental substances, such as aluminium dust or silica. People between 30 and 50 years old are most prone and often affected by this disease.

In most adult cases of PAP, problems with granulocyte-macrophage colony-stimulating factor (GM-CSF) are thought to be the cause. GM-CSF helps alveolar macrophages function properly and maintain the right amount of surfactant in the lungs.

PAP can be:

Autoimmune
Secondary
Genetic

Autoimmune PAP is mainly diagnosed in adults and is related to the presence of GM-CSF auto-antibodies.

Treatment of Pulmonary Alveolar Proteinosis

The main treatment for PAP is whole-lung lavage (WLL), also known as "lung washing." During this procedure, a healthcare provider uses a bronchoscope and sterile salt water (saline) to clean one lung at a time. This helps the patient breathe more easily. The process takes about four to five hours.

In some cases, a lung transplant may be necessary. Avoiding dust that could worsen the condition is also advised. Another treatment involves a drug called granulocyte-macrophage colony-stimulating factor (GM-CSF), which some people with PAP may be missing.

Frequently Asked Questions About Pulmonary Alveolar Proteinosis

Q. What is the life expectancy with pulmonary alveolar proteinosis?
A. Well, the life expectancy of a person with pulmonary alveolar proteinosis for five years is 95%.

Q. Is pulmonary alveolar proteinosis curable?
A. Well, it cannot be said to be curable, but patients can extend their lifespan with regular treatment. Several ways to treat pulmonary alveolar proteinosis include whole-lung lavage, lung transplant, and granulocyte-macrophage colony-stimulating factor.

Q. What causes pulmonary alveolar proteinosis?
A. Several reasons can cause pulmonary alveolar proteinosis, such as lung infection, an issue with the immune system, and exposure to substances such as silica and aluminium dust.

Q. Is pulmonary alveolar proteinosis an autoimmune disease?
A. Pulmonary alveolar proteinosis is not always autoimmune. It can also be congenital or secondary.

Q. What is the best way to treat Pulmonary Alveolar Proteinosis?
A. The best way to treat pulmonary alveolar proteinosis is through whole-lung lavage.
