  OSH Answers: Extrinsic Allergic Alveolitis
The term extrinsic allergic alveolitis refers to a group of lung diseases resulting from exposure to dusts of animal and vegetable origin.
Extrinsic allergic alveolitis does not develop on the first day of exposure to animal and vegetable dusts.
Extrinsic allergic alveolitis, once a person is sensitized, can show three different types of responses: acute (intense) response, sub-acute (recurrent) response, and chronic (long-term) response.

 Statements of Principles — Extrinsic allergic alveolitis
(b) For the purposes of this Statement of Principles, "extrinsic allergic alveolitis" means an immunologically induced inflammation of the lung parenchyma involving mainly the alveoli and terminal bronchioles, which develops secondary to repeated inhalation, by a sensitised subject, of any one of a variety of antigens, attracting ICD code 495.
Extrinsic allergic alveolitis is associated with a restrictive pattern of respiratory function tests.
Paragraphs 5(b) to 5(c) apply only to material contribution to, or aggravation of, extrinsic allergic alveolitis where the person's extrinsic allergic alveolitis was suffered or contracted before or during (but not arising out of) the person's relevant service; paragraph 8(1)(e), 9(1)(e) or 70(5)(d) of the Act refers.

 NCS - Allergic Alveolitis
Allergic Alveolitis is a respiratory hypersensitivity reaction (allergic reaction) to repeated inhalation of organic particles.
Allergic alveolitis is called a zoonotic disease, since people acquire the disease from animals (psittacosis is another zoonotic disease).
Allergic alveolitis may exhibit as either an acute, sub-acute, or chronic disease.

Extrinsic allergic alveolitis is associated with increased numbers of T and B lymphocytes in BAL fluid, as well as the presence of a few plasma cells.
The aim of this study was to investigate whether there is a relationship between the presence of plasma cells and other cells, and immunoglobulin levels in BAL fluid of patients with extrinsic allergic alveolitis.
METHODS--Thirty non-smoking patients with extrinsic allergic alveolitis who had a bronchoalveolar lavage 2-7 days after their last exposure to the causative antigen were selected, retrospectively.

 Radiology cases, Extrinsic Allergic Alveolitis
Extrinsic allergic alveolitis requires exposure to an antigen over a long period of time.
Where the process includes a combination of alveolar and immune mechanisms, it is possible to understand why extrinsic allergic alveolitis may have an initial appearance and a final appearance that are different.
Initially acute extrinsic allergic alveolitis has a ground glass appearance of alveolar opacification that proceeds through later increased fine interstitial shadowing and subsequent interstitial pulmonary fibrosis.

 Extrinsic Allergic Alveolitis -- better known in America as (COPD) Chronic obstructive pulmonary dis
The kinds of hypersensitivity diseases that are caused by bioaerosols include asthma, allergic rhinitis and (rarely) allergic dermatitis (the "immediate" or IgE-mediated diseases), and hypersensitivity pneumonitis (also called allergic alveolitis) which is mediated primarily by the cellular immune system.
Such exposure can lead to allergic alveolitis (hypersensitivity pneumonitis) or pulmonary mycoses such as coccidioidomycosis or histoplasmosis (Lacey and Dutkiewicz, 1994).
Association of fungal and pollen spores with exacerbations of asthma or allergic rhinitis is well established (Ayres, 1986) and fungal spore levels may be associated with asthma mortality (Targonski et al., 1995).

Background: Extrinsic allergic alveolitis, or hypersensitivity pneumonitis, was first described in Iceland in 1874.
The term heykatarr has been defined as "a group of related inflammatory interstitial lung diseases that result from hypersensitivity immune reactions to the repeated inhalation or ingestion of various antigens derived from fungal, bacterial, animal protein, or reactive chemical sources" (Kaltreider, 1993).
Pathophysiology: Extrinsic allergic alveolitis is the result of hypersensitivity immune reactions to the repeated inhalation or ingestion of various antigens (see the Table below).

 MnSOD in sarcoidosis and extrinsic allergic alveolitis
We found for the first time that MnSOD is highly expressed in the granulomas of sarcoidosis and extrinsic allergic alveolitis in human lung.
Western blotting revealed significantly higher level of MnSOD in the BAL cell samples in sarcoidosis and extrinsic allergic alveolitis than in the controls, and immunohistochemistry indicated that MnSOD was expressed in alveolar macrophages, but not in the lymphocytes.
Since the percentage of macrophages in the BAL samples of healthy controls is higher than in granulomatous diseases associated with relative lymphocytosis, the results of the Western blotting underestimate the real expression of MnSOD in the macrophages of these diseases.
