[A case of pulmonary infiltration with eosinophilia (PIE) syndrome associated with syndrome of inappropriate secretion of ADH (SIADH) in the elderly patient].
A 76-year-old woman was admitted to our hospital because of productive cough, fever and anorexia in January 1995. She had suffered from bronchial asthma for 25 years. From 1983, exacerbation of PIE was recorded three times, on which occasions prednisolone and antibiotics were quite effective. On admission, marked leukocytosis (28,000/microliters) and eosinophilia (18,000/microliters) were found. However, plasma IgE level was normal, and specific antigen for eosinophilia was not detected by RAST or the skin allergic reaction test. Chest X-ray film and CT scan revealed extensive bilateral pulmonary infiltration. Increase in eosinophils (33%) was demonstrated in bronchoalveolar lavage. Furthermore, biopsy specimen of the affected lung revealed diffuse infiltration of eosinophils into alveolar septa. On the basis of these findings, the patient was diagnosed as chronic eosinophilic pneumonia (PIE syndrome). Hyponatremia (117 mEq/l) was persistent after the hydration with normal saline. Plasma ADH was not suppressed (2.29 pg/ml) in spite of hypoosmolality of plasma. Laboratory examination showed that renal, adrenal and thyroid function as well as plasma renin activity were normal. Taking these findings together, she was diagnosed as having SIADH. Treatment with prednisolone improved not only the PIE syndrome but also SIADH.
