[Idiopathic pulmonary hemosiderosis].
Idiopathic pulmonary haemosiderosis (IPH) is a rare disease characterized by recurrent episodes of intrapulmonary bleeding, chronic iron deficiency anaemia and pulmonary fibrosis. IPH is a diagnosis made by exclusion of other causes. It occurs in both adults and children. Other conditions than IPH can cause pulmonary haemosiderosis. The etiology is unknown, but might be an immunological mechanism causing a defect in the basement membrane of the pulmonary capillary. IPH should be suspected in patients with recurrent episodes of coughing, haemoptysis, dyspnoea and anaemia. Chest X-ray shows pulmonary infiltrates during an acute attack. Examination of sputum or lung biopsy discloses large numbers of haemosiderin-laden pulmonary macrophages. The mortality-rate is high, but the prognosis is difficult to evaluate because many patients survive for a long time either with a course of recurrent attacks or with chronic symptoms, such as dyspnoea and persistent anaemia. Steroids may improve the condition of the patient during a bleeding episode.
