Alveoli are small bubbles inside the lungs. An adult lung contains about 400 million of these alveoli. They form an area of about 100 square meters for the exchange of oxygen and carbon dioxide.

Oxygen in the inhaled air is taken into the blood and carbon dioxide is discharged from the blood into the air in alveoli. Lungs are inflamed by some factors. It represents an allergic response to proteins or fungal spores (allergens), organic dusts (exogenous allergic Alveolitis, EAA). Immune system reacts incorrectly fungal spores or animal proteins in the dust.

A alveolitis may occur suddenly with severe symptoms or progress slowly over a longer period with different complaints. EAA (exogenous allergic Alveolitis) is a relatively rare disease. Most often,it is called’’bird fancier’s lung , farmer’s lung and humidifier lung’’.

Also the contact with proteins of rodents can trigger an EAA. Farmer’s lung: The farmer’s lung is the second most common form of extrinsic allergic alveolitis. It is caused by an allergic reaction to mold spores in moldy hay.

EAA often occurs six to 16 hours after contact with the allergen. Sufferers feel sick, have body aches, cough and shortness of breath. Sometimes occurs fever. The nose and throat is inflamed as a cold. The symptoms can be easily confused with pneumonia. If allergen contact is interrupted,allergen problem decreases within two to four days.

A alveolitis can occur due to an allergic reaction to proteins or mold spores. First, the immune system for a particular allergen such as mold spores is sensitized. It produces antibodies against them. If the spores inhale again, the immune system is triggered to react response as an inflammatory in the alveoli. There are more than 300 allergens known that can trigger a hypersensitivity pneumonitis.

Although the disease is rare, but it occurs more often in high-risk groups such as bird breeders or farmers. Smokers develop more rarely an EAA which causative reasons are unknown.

A alveolitis must be treated as quickly as possible. In many cases, is treated with cortisone to stop the inflammatory process as quickly as possible. If breathing is difficult, a cortisone inhalation spray can help better. Partially other drug inhibitors of the immune system such as azathioprine or cyclophosphamide must be used to stop the inflammatory process.

Alveolitis Disease Progression and Prognosis

If it is possible for the people who are concerned to avoid the allergens which cause EAA , disesase often heals by itself. If the disease is discovered late without any treatment , lung structure may take permanent damage. The lung structure thickens and lung becomes less elastic (pulmonary fibrosis). The heart must pump at a thickened lung structure against a higher resistance. This may also cause damage heart in the long run.
