Pulmonary Renal Syndrome
Introduction
Pulmonary-renal syndrome combines both diffuse alveolar hemorrhage (recurrent or persistent bleeding into the lungs) and glomerulonephritis (damage to the microscopic blood vessels in the kidneys in which people have body swelling, high blood pressure, and red blood cells in the urine). Pulmonary-renal syndromes are almost always caused by an Autoimmune Disorders . Diagnostic testing involves urinalysis, blood tests for certain proteins (antibodies) that indicate the body is reacting to its own tissues, and sometimes analysis of tissue from a lung or a kidney. Treatment requires corticosteroids and oftencyclophosphamide(a chemotherapy drug) orrituximaband other medications that suppress the body's immune system. 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 ( Pulmonary-renal syndrome is a syndrome, rather than a specific disorder. A syndrome is a group of symptoms and other abnormalities that occur together but may be caused by several different disorders or even other syndromes. Pulmonary-renal syndrome involves a lung disorder called Diffuse Alveolar Hemorrhage , which is widespread damage to the small blood vessels that supply the lungs, causing blood to accumulate in the lung's tiny air sacs (alveoli). People also have a type of kidney problem called
