Clinical Features for Gold Lung (Gold Compound Hypersensitivity Pneumonitis)

Has the patient had an acute or subacute onset of respiratory signs and symptoms?

Does the chest X-ray show a diffuse interstitial and/or alveolar filling pattern?

Does the broncho-alveolar lavage (BAL) show a lymphocytosis?

Were lymphocyte subclasses measured on the BAL fluid?

CD4 (helper) count in the BAL

CD8 (suppressor) count in the BAL

Has discontinuation of the gold therapy resulted in a clinical improvement?

Has the patient responded promptly to corticosteroid therapy?

Is there another diagnosis that can explain all of the findings better?
