[Extrinsic allergic alveolitis: a review for the practitioner].
Extrinsic allergic alveolitis (EAA) or hypersensitivity pneumonitis (HP) is a clinical syndrome characterised by an inflammatory, partly granulomatous, immune disorder involving interstitial and alveolar spaces secondary to inhalation of organic substances. The disorder is mainly due to occupational exposure, farmer's lung being the best-known example. Acute, subacute or chronic forms can be clinically differentiated. Given the fact that chronic forms may present a pattern of irreversible pulmonary fibrosis, clinicians must be aware of the diagnosis of EAA in every situation where the history shows a potential antigenic exposure. Prevention should be reinforced by increasing individual protective measures and by improving techniques used at the workplace.
