Hypersensitivity Pneumonia Is A Variety Of Interstitial Lung Disease.

Hypersensitivity intends an inappropriate immune response to an antigen. Pneumonitis intends inflammation of the lungs. Hypersensitivity pneumonitis is, therefore, an unsuitable immune response to an antigen or allergen resulting in the information of the lungs.

That is why hypersensitivity pneumonitis is likewise known as extrinsic allergic alveolitis. Some people may become sensitized to distinct antigens after previous exposure. This intends that they may develop antibodies against the antigen typically the IgG.

In the subsequent presentation, the immune system will trigger an inappropriate immune reply to the culprit antigen. The hypersensitivity reaction in that lungs comes from repeated inhalation of environmental antigens before-mentioned as hot tubes, Mold, birds, down feathers in a sensitized person.

The hypersensitivity reactions result in alveolar thickening and noncaseating granulomas with peribronchial mononuclear cell infiltration with faint cells. There are many antigens that people sniff either from where people work or where people live generating this disease. Over 300 cases have been reported.

Many of these events have been named such as a Farmer's lung, bird fanciers lung, and even coffee workers lung. Removal of susceptibility to the offending antigen is required in the treatment of hypersensitivity pneumonitis.
