vx-770 and Alveolitis--Extrinsic-Allergic

A 48-year-old woman sought a second opinion for dyspnea and chronic productive cough; she was a never smoker. Mild respiratory symptoms persisted since childhood and had progressively worsened over the previous decade. In addition, an unintentional 30-pound weight loss had occurred over several years. Six years previously, a diagnosis of hypersensitivity pneumonitis was made following right upper lobe wedge resection that revealed chronic bronchiolitis with interstitial pneumonia and non-necrotizing granulomatous inflammation. Subsequent use of prednisone elicited mild intermittent improvement. She had used feather pillows in the past without any other significant exposures. There were no reports of sinus or GI symptoms.
