Of 46 patients with sarcoidosis, there was an exposure to type III allergens in 14 subjects. On closer examination of 2 patients diagnosed as having sarcoidosis there were distinct features suggesting farmer's lung too. Inhalative challenge recording airway resistance, CO transfer factor and other clinical features confirmed farmer's lung disease in these patients. Because there are sometimes poor clinical and uncertain histological differences, inhalative challenge is considered an important diagnostic procedure to differentiate hypersensitivity pneumonitis from sarcoidosis.
在46例结节病患者中，14例曾接触III型变应原。在对2例诊断为结节病的患者进行更仔细检查时，发现有明显特征提示也患有农民肺。吸入激发试验记录气道阻力、一氧化碳弥散因子及其他临床特征，证实这些患者患有农民肺疾病。由于有时临床差异不明显且组织学表现不明确，吸入激发试验被认为是区分过敏性肺炎与结节病的重要诊断方法。
