Granulomatosis with polyangiitis (GPA) is a rare form of vasculitis that restricts blood flow.
Also called Wegener’s granulomatosis, GPA produces nodules of inflamed tissue around blood vessels. Sometimes sores develop in the respiratory tract or the kidneys, which can have serious consequences.
There are many early symptoms of GPA, including the following:
- Frequent sinusitis
- A lingering fever
- Night sweats
- Nose bleeds
- Chronic ear infections

Other symptoms may include the following:
- Joint pain
- Loss of appetite, weight loss
- Blood in the urine
- Eye problems, such as conjunctivitis
- Chest pain
- Shortness of breath and wheezing
- It is not known what triggers the immune system to overproduce the antibodies causing GPA; however, it may be a combination of an infection and genetic predisposition.
- With treatment, most patients recover; however, the disease returns in about half of all patients. In these cases, the disease usually comes back within two years of stopping treatment.
- Complications, including kidney failure, usually result from lack of treatment. If untreated, kidney failure and death occur in more than 90 percent of patients.
