Impaired quality of life in chronic hypersensitivity pneumonitis.

We read with interest in an issue of CHEST (June 2014) the article by Lubin et al, 1 who compared Short Form-36 quality of life (QOL) among patients with idiopathic pulmonary fi brosis (IPF) and chronic hypersensitivity pneumonitis (CHP). Th e authors noted that they were surprised to fi nd that QOL scores were signifi cantly better in IPF than CHP in seven of eight domains. Th ey demonstrated that this fi nding did not relate to age or severity of lung function impairment, and they discussed possible explanations.
