Successful treatment of hypersensitivity pneumonitis caused by Grifola frondosa (Maitake) mushroom using a HFA-BDP extra-fine aerosol.

We successfully treated a patient with occupational hypersensitivity pneumonitis (HP) caused by Grifola frondosa (Maitake) mushroom spore with an extra-fine aerosol corticosteroid; beclomethasone dipropionate (BDP) dissolved in hydrofluoroalkane-134a (HFA). A 49-year-old woman developed respiratory symptoms 3 months after beginning work on a mushroom farm. She was diagnosed as HP based on radiological and serological findings.

Workplace-related chronic cough on a mushroom farm.

Background: Mushroom spores have frequently been associated with respiratory allergy. The aims of this study were to elucidate the incidence and causes of chronic cough in a mushroom farm.

Methods: Participants were 69 mushroom workers who produce Hypsizigus marmoreus (Bunashimeji) and 35 control subjects.

Hypersensitivity pneumonitis induced by the spore of Pleurotus Eryngii (Eringi).

We reported the first case of hypersensitivity pneumonitis (HP) by an edible mushroom, Pleurotus Eryngii (Eringi). A 54-year-old woman had worked in a Bunashimeji mushroom factory for 42 months, and she moved to a new factory producing Eringi. Two months after, she was found to have HP by the spore of Eringi.
