Complications
By Mayo Clinic staffChurg-Strauss syndrome can affect many organs, including your lungs, skin, gastrointestinal system, kidneys, muscles, joints and heart. Without treatment, the disease may be fatal. Complications depend on the organs involved and may include:
- Peripheral nerve damage. Peripheral nerves extend throughout your body, connecting your organs, glands, muscles and skin with your spinal cord and brain. Churg-Strauss syndrome can damage peripheral nerves (peripheral neuropathy), especially those in your hands and feet, leading to numbness, burning and loss of function. Peripheral nerve problems often improve with treatment.
- Skin scarring. The inflammation may cause sores to develop that can leave scars.
- Heart disease. Heart-related complications of Churg-Strauss syndrome include inflammation of the membrane surrounding your heart (pericarditis), inflammation of the muscular layer of your heart wall (myocarditis), heart attack and heart failure.
- Kidney (renal) damage. If Churg-Strauss syndrome affects your kidneys, you may develop glomerulonephritis, a type of kidney disease that hampers your kidneys' filtering ability, leading to a buildup of waste products in your bloodstream (uremia). Kidney failure is uncommon.
