Elevated levels of beta-D-glucan in bronchoalveolar lavage fluid in patients with farmer's lung in Miyazaki, Japan.

Background: Farmers may be often exposed to beta-D-glucan in moldy hay, since straw for feed can be stored throughout the year.

Objectives: The aim of the present study was to clarify whether levels of beta-D-glucan, which modifies immune responses, are high in the respiratory tract in farmer's lung and whether beta-D-glucan participates in the pathogenesis of this condition.

Methods: We measured beta-D-glucan levels in the bronchoalveolar lavage fluid (BALF) of 10 patients with farmer's lung, 4 with summer-type hypersensitivity pneumonitis (HP) and 10 healthy volunteers.
