Idiopathic pulmonary<unk>  (IPH) is a rare disease of unknown etiology characterized by repeated episodes of a diffuse alveolar hemorrhage which cause periodic attack of tachycardia, pyrexia, pallor, fatigue, cyanosis, increasing dyspnea, signs of congestive cardiac failure, severe anamia and hemoptysis. The repeated alveolar hemorrhage causes the accumulation of hemosiderin, a by-product of hemoglobin breakdown, in the alveoli. Alveolar macrophages take up these hemosiderin molecules, usually within 36 - 72 hours, and can remain in the lungs for up to 8 weeks. Between attacks, patients may remain well but commonly there is chronic ill-health. Over the time, It  can lead to multiple respiratory complications and permanent lung damage. It is not familial and is found primarily in children from a few months to 16 years of age and rarely be seen in adults.
