Abstract |
A 47-year old man presented to our hospital with a 6-month history of malaise, cough and dyspnea on exertion. Laboratory testing revealed the severe hyponatremia. A chest X-ray showed bilateral diffuse micronodules. Anti-Trichosporon asahii antibody and environmental provocation test were positive. Bronchoalveolar lavage fluid showed lymphocytosis and low CD4/8 ratio. The specimens obtained by transbronchial lung biopsy revealed alveolitis. Based on these findings, the patient was diagnosed as having summer-type hypersensitivity pneumonitis (SHP). The patient was treated with antigen avoidance and oral corticosteroid. The hyponatremia caused by syndrome of inappropriate secretion of antidiuretic hormone ( SIADH) was treated with normal saline and water restriction. Serum sodium level was improved with treatment of SHP, which suggested the relevance between SHP and SIADH.
