Hypersensitivity Pneumonitis (Overview)

A non-ige mediated, immunologically mediated lung disease with generalized symptoms due to sensitization of a wide variety of inhaled organic dusts. These include molds, birds and other antigens found especially in workplaces and hobbies. It affects lung alveoli and can have acute (appears like viral pneumonia), subacute and chronic forms. No one test confirms the disease.

Acute hypersensitivity pneumonitis fatal?

Not usually: Not usually, however very heavy exposure to the inciting agent or very severe responses can cause severe lung injury and result even in respiratory failure. Even in these situations if medical care is sought out the response to steroid medicine is usually very good. Repeat exposures that are untreated can cause a more chronic scarring of the lung or pulmonary fibrosis that can shorten ones life. ...Read more
