Further Care

Further outpatient care

Serial pulmonary function testing with assessment of lung volumes and diffusion capacity is indicated (if the patient is able to perform the maneuvers) to document resolution of abnormalities. Monitor adherence to recommendations to eliminate exposure to the offending antigen.

The patient with hypersensitivity pneumonitis (HP) should be strongly advised to eliminate exposure to the offending antigen. In cases of severe disease, the patient may need to be moved to a new setting to avoid the offending antigen. In some cases, antigen avoidance may include interventions that are very disruptive to the individual’s life or the family’s life, such as removing a family pet, moving from the home, changing occupations or both.

Corticosteroid doses and adverse effects must be monitored. Once a clinical response has been achieved, the acute dosing should be gradually tapered. Markers of clinical response consist of resolution of abnormalities on physical and radiologic examination, improvement in pulmonary function measures including vital capacity, diffusing capacity, and oxygen saturation.

Further inpatient care

Monitor corticosteroid doses and adverse effects. Gradually taper dose after clinical response, visible clearing on radiographs, and improved pulmonary function are achieved.


The immediate family of children with chronic HP should be screened for subclinical disease because both the exposure and genetic predisposition may be shared.
