Diagnosis and Management of Hypersensitivity Pneumonitis (HP)

Hypersensitivity pneumonitis (HP) is an interstitial lung disease caused by an allergic reaction to organic environmental antigens, such as mold or bird feathers. Kevin Dsouza, MD, a pulmonologist, discusses the complex diagnosis and management of HP: how specialists distinguish HP from other diseases by analyzing acute symptoms, patient histories, and CT scans; how cases of fibrotic and nonfibrotic HP are treated differently; and how physicians can help patients to identify and prevent exposure to the culprit antigen.
