Diffuse Alveolar Hemorrhage
Introduction
Diffuse alveolar hemorrhage is a syndrome of recurrent or persistent bleeding into the lungs, caused most often by an Autoimmune Disorders . Common symptoms are difficulty breathing and coughing, often coughing up blood. People usually have chest imaging, blood tests, and sometimes examination of the breathing passages with a flexible viewing tube (bronchoscopy). Treatment of autoimmune causes involves suppression of the immune system with corticosteroids and oftencyclophosphamide(a chemotherapy drug) orrituximab(a type of immune suppression medication). An important function of the Overview of the Immune System is fighting off infections. To do this, the immune system recognizes microorganisms as foreign to the person and produces proteins ( Diffuse alveolar hemorrhage is a syndrome, not a particular disorder. A syndrome is a group of symptoms and other abnormalities that occur together but may be caused by several different disorders.

Such blood vessel damage can result from several disorders.
