A 44-year-old man was hospitalized because of exertional dyspnea that had progressed for one month. A chest X-ray film showed bilateral small nodular and reticular shadows. The patient presented with a positive inflammatory reaction and hypoxemia. Bronchoalveolar davage fluid had a high lymphocyte fraction and a low CD4/CD8 ratio. Trichosporon cutaneum antibodies were detected, and a specimen obtained by transbronchial lung biopsy showed alveolitis with granuloma formation. The patient reacted positively on a provocation test that was done by having him stay home for 5 days. Summer-type hypersensitivity pneumonitis was diagnosed, and a steroid was administered because of the prolonged abnormal chest roentgenographic findings. KL-6, a mucinous high-molecular-weight glycoprotein that is expressed on Type II pneumonocytes, was retrospectively used as a marker of pneumonitis. A new kit for enzyme-linked immunoassay (ED046) was used to measure the serum KL-6 level. The serum KL-6 level peaked approximately 10 days after the patient was admitted to the hospital and was thus kept away from antigens, and also after the provocation test. The steroid treatment was started, the KL-6 level decreased gradually. Within 2 months after steroid treatment began, the dose of the steroid was reduced and the KL-6 level decreased below the upper limit of normal. The KL-6 level remained low thereafter; it was not influenced by liver dysfunction or other inflammatory processes. However, the C-reactive protein level decreased rapidly after provocation and thereafter immediately returned to almost zero. The lactate dehydrogenose level peaked 8 days after provocation and decreased rapidly after steroid treatment. These results suggest that the serum KL-6 level provides new information regarding the clinical course and treatment of interstitial pneumonia. In addition KL-6 may be useful form monitoring disease activity, especially while tapering the dose of steroids in patients with interstitial pneumonia.

Summer-type hypersensitivity pneumonitis (SHP) is the most common form of pneumonitis in Japan; it accounts for 74% of all cases. It has been reported that 19.5-23.8% of SHP cases occur in families who live in the same house. We present our SHP cases and review 50 familial cases in 23 families that were reported in Japan (including our own) and 48 cases that were previously described in 22 articles published between January 1982 and October 2011. To the best of the authors' knowledge, this is the first review article in English to document the familial occurrence of SHP in Japan.
