Granulomatosis with Polyangiitis (Wegener's)

What is Granulomatosis with Polyangiitis (Wegener's)?

Granulomatosis with Polyangiitis (GPA), also known as Wegener's granulomatosis, is characterized by inflammation of small to medium-sized blood vessels.

This inflammation can lead to the formation of granulomas (small masses of inflamed tissue) and damage to the affected organs.

Common symptoms include persistent sinusitis, lung involvement (such as cough, shortness of breath), and kidney problems (such as blood in urine or kidney failure).

Side Effects of Granulomatosis with Polyangiitis (Wegener's)

The effects of Granulomatosis with Polyangiitis can vary widely depending on which organs are involved. Potential side effects and complications may include:

• Respiratory System: Chronic sinus infections, nosebleeds, coughing up blood, lung nodules, and ultimately respiratory failure.
• Renal System: Blood in urine, kidney inflammation, and potentially kidney failure.
• Other Organs: In some cases, GPA can affect the skin, joints, eyes, and nervous system, leading to a range of symptoms and complications.

How is Granulomatosis with Polyangiitis (Wegener's) Diagnosed?

Diagnosing Granulomatosis with Polyangiitis often involves a combination of medical history review, physical examination, imaging tests (such as X-rays or CT scans), blood tests (including tests for markers of inflammation and specific antibodies), and sometimes a biopsy of affected tissue.

A comprehensive evaluation is crucial to confirm the diagnosis and assess the extent of organ involvement.

Potential Treatment of Granulomatosis with Polyangiitis (Wegener's)

Treatment for Granulomatosis with Polyangiitis typically involves a combination of medications to suppress the immune system and reduce inflammation. This may include:

• Corticosteroids: Initially used at high doses to control inflammation.
• Immunosuppressive Drugs: Such as methotrexate, azathioprine, or rituximab, which are used to prevent the immune system from attacking the body's tissues.
• Biological Therapies: Drugs targeting specific components of the immune system, such as rituximab, may be prescribed in more severe cases.
