Goodpasture syndrome

Goodpasture (GPS), also known as anti–glomerular basement disease, is a rare disease in which attack the basement membrane in lungs and kidneys, leading to bleeding from the lungs, glomerulonephritis, and kidney failure. It is thought to attack the alpha-3 subunit of type IV collagen, which has therefore been referred to as Goodpasture's antigen. Goodpasture syndrome may quickly result in permanent lung and kidney damage, often leading to death. It is treated with medications that suppress the system such as and cyclophosphamide, and with plasmapheresis, in which the antibodies are removed from the blood. Due to the GPS's rapid progression, the significant difficulty of treating the disease is identifying it early and making the appropriate response before severe damage occurs to the kidneys and or lungs. Consequently, the standard treatment plan of corticosteroids, cyclophosphamide, and plasmapheresis is vigorous and fast-acting, including high volume exchange and an intensive dose of corticosteroid and cyclophosphamide based on the patient's body weight in kilograms.
