Renal vasculitis, also called ANCA glomerulonephritis, is an autoimmune disease that causes your white blood cells to attack the glomeruli, the tiny blood vessels that filter blood in your kidneys. This causes swelling and damage to the capillaries (blood vessels). When the glomeruli can’t filter the blood, protein and blood leak into the urine, which can lead to loss of kidney function or kidney failure in severe cases.
There are two main types of renal vasculitis:
- Microscopic polyangiitis (MPA): affects small arteries and veins, and it can also affect your joints, lungs, gastrointestinal system, nerves, and skin
- Granulomatosis with polyangiitis (Wegner’s disease): causes swelling of the blood vessels in your kidneys, lungs, sinuses, and throat
Some people don’t experience any noticeable symptoms until the disease is more advanced. When symptoms do occur, they include abdominal pain, blood in your urine, and a rash on your buttocks or lower legs.
Kidney specialists (nephrologists) at University of Miami Health System are experienced in diagnosing and treating renal vasculitis. We develop a customized treatment plan to improve kidney function and give you relief from symptoms.
