Abstract

The syndrome of inappropriate ADH secretion (known as SIADH) is characterized by hyponatremia that result from watr retention attributable to inappropriate or excessive secretion of ADH. SIADH was originally described by Schwartz in 1957. It was more fully characterized by Bartter and Schwartz in 1967, and it is now well known that inappropriate ADH secretion may be associated with the disease process of host including CNS disorders, pulmonary diseases, endocrine disorders. It may be also be secondary to medications and tumors, notably bronchogenic carciδoma ofthe ‘oat’ cell type. We experienced a case of bacterial pneumonia associated with SIADH who had admitted with dyspnea and chest pain. The bacterial pneumonia was diagnosed by chest P-A, chest CT, and sputum culture and treated with antibiotics. Also SIADH was diagnosed from hyponatremia, increased urinary sodium excretion, high urine osmolality than that of plasma, and exclusion of other causes of hyponatremia and treated with hypertonic solution and water restriction. Described here a case of bacterial pneumonia associated with SIADH with some review of literature.
