Wegener’s granulomatosis is a condition of the immune system that causes swelling and irritation in blood vessels and other tissues.

This inflammation reduces or stops the flow of blood to organs in the body. The condition most often affects the respiratory tract–the sinuses, nose, windpipe, and lungs–and the kidneys, but it can damage any organ in the body.
Wegener’s granulomatosis is uncommon. It occurs in about one out of 20,000 to 30,000 people. It can strike at any age. The cause of Wegener’s granulomatosis is still unknown.
Signs and symptoms
Most people with Wegener’s granulomatosis first report vague symptoms that may include:
Tiredness or exhaustion
Upper respiratory symptoms that don’t respond to treatments for allergies or colds:
Blockage of the eustachian tubes in the ears
Cough that produces blood
Shortness of breath
Eye infections, redness, burning, or pain
Skin sores or ulcers
Ongoing Wegener’s granulomatosis can result in:
Collapse of cartilage in the nose
Infections of sinuses and ears
When to call a doctor
Call your doctor if you are experiencing the symptoms listed above, especially if you have tried over-the-counter treatments that seem appropriate, such as allergy medications, with no success.
Always call your doctor if you have changes in vision or a cough that produces bloody mucus, which may be symptoms of Wegener’s granulomatosis or another serious health condition.
Your doctor visit may include:
Taking your medical history
Review of your symptoms
Blood tests. These can’t diagnose Wegener’s granulomatosis, but they can rule out other causes of your symptoms.
Antineurtophil cytoplasmic antibody (ANCA) blood test. In addition to routine blood tests, health care providers will often look for this specific antibody, but a positive or negative test does not confirm the diagnosis.
Imaging tests, such as chest X-rays or CT scans of the lungs or sinus
Biopsy, or taking a sample of tissue from an affected organ to see whether the condition is present. This is the only way to know for sure if it’s Wegener’s granulomatosis.
Most people with Wegener’s granulomatosis will find relief. But the drugs used to treat this condition all have potential side effects of their own. Be sure to discuss these side effects in detail with your doctor.
These are common medications used in treatment:
Prednisone. This is a steroid that helps reduce inflammation. Long-term steroid use can affect your bone health, so your doctor may also monitor and treat changes in your bone density.
Cyclophosphamide (also called Cytoxan). This is used to treat active Wegener’s granulomatosis.
Methotrexate. This drug may be given to keep symptoms in remission for one to two years. You may need to take folic acid supplements with this drug.
Azathioprine. This is an alternative to methotrexate.
Rituximab. This medication may be given in combination with prednisone to treat Wegener’s granulomatosis and bring about remission.
Antibiotics (also called Imuran). Certain infections are more common among people with this condition. Antibiotics may be given to treat or prevent infection.
Wegener’s granulomatosis may return even after successful treatment. Continue to follow up with your doctor, even when you are in remission.
