Granulomatosis with polyangiitis (GPA)

Granulomatosis with polyangiitis (GPA) is a type of vasculitis , which is an inflammation of the blood vessels. Symptoms vary between people, and can be mild or severe. In some people, they come on slowly over many months, and in others they appear suddenly. General symptoms may be mild and start before symptoms in specific parts of the body. They can include: high temperature night sweats feeling weak and tired joint pain loss of appetite weight loss Other symptoms depend on which parts of your body are affected, so you may not have all the symptoms. Symptoms that may affect specific parts of the body Body part Possible symptoms Ears, nose and sinuses Ear infection, hearing loss, blocked or runny nose, crusting of blood and mucus in the nose, nosebleeds, sinus pain Eyes Conjunctivitis, swollen eyelids, double vision, blurred vision Lungs A cough that does not go away, coughing up blood, shortness of breath, chest pain, wheezing Kidneys High blood pressure, swelling in the legs, kidney failure Skin Rashes, ulcers, small spots Stomach Tummy pain, diarrhoea, blood in poo

There's no single test for granulomatosis with polyangiitis (GPA) and it can be difficult to diagnose. A GP will ask about your symptoms and may examine the affected part of your body. If they think you could have GPA they'll refer you to a specialist. You'll have tests such as: a blood test to see if you have an antibody called ANCA (antineutrophil cytoplasmic antibodies), which may be a sign of GPA a biopsy , where a small sample of tissue from any affected body parts is sent for testing an X-ray , CT scan or MRI scan of any affected body parts a urine (pee) test if you have symptoms affecting your kidneys

You'll be treated by a specialist if you have granulomatosis with polyangiitis (GPA). Treatment depends on how severe it is and the body parts affected. There are 2 stages of treatment – bringing the condition under control and keeping it under control. Stage 1: Bringing the condition under control If you have mild GPA, you may be given an anti-inflammatory medicine called a steroid to control your symptoms. You may also have an immunosuppressant medicine such as methotrexate . If you have severe GPA, you may be given a biological medicine such as rituximab or avacopan, or both, along with steroids. You may also be given a type of chemotherapy medicine, such as cyclophosphamide, to bring it under control. Stage 2: Keeping the condition under control Once the condition is under control, treatment aims to stop your symptoms coming back. You may have lower doses of your medicines or take a different type of medicine. Treating symptoms if they come back If your symptoms come back or you get new symptoms (a relapse), your treatment may be changed or restarted. Treating severe cases In very severe cases that affect the kidneys, you may need dialysis or a kidney transplant. You may also need surgery to the affected body part if you have complications from GPA, for example reconstructive surgery if the bridge of the nose has been damaged.

If you have granulomatosis with polyangiitis (GPA), your care team will pass information on to the National Congenital Anomaly and Rare Disease Registration Service (NCARDRS) . It's used to help scientists look for better ways to prevent and treat this condition. You can opt out of the register at any time.
