A 54-year-old woman was admitted to Nayoro City Hospital because of a suspicion of farmer's lung (FL). She had been working on her farm for the previous 16 years. Every April she experienced fever, coughing, and dyspnea. Fine crackles were audible over both lung fields. On admission, arterial blood gas analysis showed hypoxemia, and pulmonary-function testing revealed restrictive lung disease and a low diffusing capacity. A chest X-ray film revealed radio-opacity throughout the lower lung fields. A 67Ga scintigram showed abnormal uptake in the lungs. Examination of bronchoalveolar lavage fluid revealed an abnormally high number of lymphocytes and a high CD4/CD8 ratio in the lymphocytes. Histological examination of a specimen obtained by transbronchial lung biopsy revealed interstitial pneumonitis. A precipitation test was positive for anti-Micropolyspora faeni antibody. After admission, symptoms resolved with no treatment. FL was diagnosed from anamnesis and the results of examinations. On admission, the level of soluble interleukin 2 receptor in serum was twice the upper limit of the normal value, and it decreased over time, a long with the severity of the disease. Serial measurements of levels of this receptor are clinically important for detecting the progression of adult T cell leukemia. This case suggests that they can also be useful for evaluating the severity of FL.

Safety, local and systemic immunomodulation, and tumor response to treatment with aerosolized natural interleukin 2 (nIL-2) applied five times a day were studied in a Phase I trial in 16 patients with pulmonary malignancies refractory to conventional therapy. The toxicity of inhaled nIL-2 was different from that observed after systemic administration. Reversible airway irritation causing a nonproductive cough represented the dose-limiting toxicity. Mild to moderate reduction of the vital capacity and forced expiratory volume (FEV1) with minor effects on relative FEV1, peak expiratory flow, airway resistance, and PaO2 was experienced by individual patients. In 14 patients suffering from pulmonary metastases due to renal cell cancer, one durable complete response, one partial response, and one mixed response were observed. Inhalation of nIL-2 aerosol resulted in a dose-dependent expansion of pulmonary immunocompetent cells in bronchoalveolar lavage fluid. Posttreatment bronchoalveolar lavage showed an activated lymphocyte phenotype with increased HLA-DR expression. The only systemic biological effect detectable in peripheral blood was a marked increase of soluble interleukin 2 receptor serum levels. We conclude that treatment with aerosolized nIL-2 is an effective means for site-specific immunomodulation and deserves further investigation for the treatment of malignant and inflammatory lung disease.
