URL of this page: From Genetics Home Reference. Learn more Granulomatosis with polyangiitis (GPA) is a condition that causes inflammation that primarily affects the respiratory tract (including the lungs and airways) and the kidneys. This disorder is formerly known as Wegener granulomatosis. A characteristic feature of GPA is inflammation of

blood vessels (vasculitis), particularly the small- and medium-sized blood vessels in the lungs, nose, sinuses, windpipe, and kidneys, although vessels in any organ can be involved. Polyangiitis refers to the inflammation of multiple types of vessels, such as small arteries and veins. Vasculitis causes scarring and tissue death in the vessels and impedes

blood flow to tissues and organs.Another characteristic feature of GPA is the formation of granulomas, which are small areas of inflammation composed of immune cells that aid in the inflammatory reaction. The granulomas usually occur in the lungs or airways of people with this condition, although they can occur in the eyes or other organs. As

granulomas grow, they can invade surrounding areas, causing tissue damage.The signs and symptoms of GPA vary based on the tissues and organs affected by vasculitis. Many people with this condition experience a vague feeling of discomfort (malaise), fever, weight loss, or other general symptoms of the body's immune reaction. In most people with

GPA, inflammation begins in the vessels of the respiratory tract, leading to nasal congestion, frequent nosebleeds, shortness of breath, or coughing. Severe inflammation in the nose can lead to a hole in the tissue that separates the two nostrils (nasal septum perforation) or a collapse of the septum, causing a sunken bridge of the nose (saddle

nose).The kidneys are commonly affected in people with GPA. Tissue damage caused by vasculitis in the kidneys can lead to decreased kidney function, which may cause increased blood pressure or blood in the urine, and life-threatening kidney failure. Inflammation can also occur in other regions of the body, including the eyes, middle and inner ear

structures, skin, joints, nerves, heart, and brain. Depending on which systems are involved, additional symptoms can include skin rashes, inner ear pain, swollen and painful joints, and numbness or tingling in the limbs.GPA is most common in middle-aged adults, although it can occur at any age. If untreated, the condition is usually fatal within 2 years

of diagnosis. Even after treatment, vasculitis can return. GPA is a rare disorder that affects an estimated 3 in 100,000 people in the United States. The genetic basis of GPA is not well understood. Having a particular version of the HLA-DPB1 gene is the strongest genetic risk factor for developing this condition, although several other genes, some of

which have not been identified, may be involved. It is likely that a combination of genetic and environmental factors lead to GPA.GPA is an autoimmune disorder. Such disorders occur when the immune system malfunctions and attacks the body's own tissues and organs. Approximately 90 percent of people with GPA have an abnormal immune protein

called an anti-neutrophil cytoplasmic antibody (ANCA) in their blood. Antibodies normally bind to specific foreign particles and germs, marking them for destruction, but ANCAs attack normal human proteins. Most people with GPA have an ANCA that attacks the human protein proteinase 3 (PR3). A few affected individuals have an ANCA that attacks

a protein called myeloperoxidase (MPO). When these antibodies attach to the protein they recognize, they trigger inflammation, which contributes to the signs and symptoms of GPA.The HLA-DPB1 gene belongs to a family of genes called the human leukocyte antigen (HLA) complex. The HLA complex helps the immune system distinguish the body's

own proteins from proteins made by foreign invaders (such as viruses and bacteria). Each HLA gene has many different normal variations, allowing each person's immune system to react to a wide range of foreign proteins. A particular variant of the HLA-DPB1 gene called HLA-DPB1*0401 has been found more frequently in people with GPA,

especially those with ANCAs, than in people without the condition.Because the HLA-DPB1 gene is involved in the immune system, changes in it might be related to the autoimmune response and inflammation in the respiratory tract and kidneys characteristic of GPA. However, it is unclear what specific role the HLA-DPB1*0401 gene variant plays in

development of this condition. The inheritance pattern of GPA is unknown. Most instances are sporadic and occur in individuals with no history of the disorder in their family. Only rarely is more than one member of the same family affected by the disorder. Lamprecht P, Wieczorek S, Epplen JT, Ambrosch P, Kallenberg CG. Granuloma formation in

Granulomatosis with polyangiitis is an uncommon disease that involves inflammation of

blood vessels (vasculitis).Symptoms of granulomatosis with polyangiitis include:Diagnosis of granulomatosis with polyangiitis is confirmed by detecting both abnormal cellular formations, called granulomas, and vasculitis.Treatment is directed toward stopping the inflammation process by suppressing the immune system.What is granulomatosis with

polyangiitis? Granulomatosis with polyangiitis (GPA) is an uncommon type of inflammation of small arteries and veins (vasculitis). It classically involves inflammation of the arteries that supply blood to the tissues of the lungs, the nasal passages (sinuses), and the kidneys. "Incomplete" forms exist that only involve one of these areas. When both lungs

and kidneys are affected, the condition is sometimes referred to as generalized granulomatosis with polyangiitis. When only the lungs are involved, the condition is sometimes referred to as limited granulomatosis with polyangiitis. The terminology "granulomatosis with polyangiitis" highlights the two central pathologic features of the disease,

granuloma formation and inflammation of blood vessels (angiitis or vasculitis).The name "Wegener's granulomatosis" is no longer used because the German physician Friedrich Wegener, the disease's former namesake, was a member of the Nazi party and allegedly linked to Nazi war crimes.Granulomatosis with polyangiitis usually affects young or

middle-aged adults. Although it is uncommon in children, it can affect people at any age. The cause of the condition is not known. Joint pain is also referred to as arthralgia. Pain is a feature symptom of joint inflammation with diseases and conditions such as rheumatoid arthritis and osteoarthritis. Joint pain also may be caused by an injury to the

ligaments, bursae, tendons, bones, and cartilage surrounding and within the joint. Joint pain also is a symptom of Wegener's granulomatosis. Pain within the joint is a common cause of shoulder pain, ankle pain, and knee pain. Read more about the symptoms and possible causes of joint pain ?

Readers Comments 52 Share Your Story Symptoms of granulomatosis with polyangiitis include:Nasal ulcerations and even bloody nasal discharge can occur. Other areas of the body that can also become inflamed in patients with GPA include the eyes, the nerves (neuropathy), the middle ear (otitis media), and the skin resulting in skin nodules or

ulcers.How is granulomatosis with polyangiitis diagnosed? Abnormal lab findings in patients with granulomatosis with polyangiitis include urine tests that detect protein and red blood cells in the urine (not visible to the naked eye) and X-rays of the chest and sinuses, which detect abnormalities resulting from lung and sinus inflammation. Blood tests

that detect the abnormal inflammation include the sedimentation rate (sed rate) and C-reactive protein. A more specific blood test used to diagnose and monitor granulomatosis with polyangiitis is the antineutrophil cytoplasmic antibody (ANCA test), which is commonly elevated when the disease is active.The diagnosis of granulomatosis with

polyangiitis is confirmed by detecting both abnormal cellular formations, called granulomas, and vasculitis in a biopsy of tissue involved with the inflammatory process. For examples, an open lung biopsy or a kidney biopsy are commonly used in making a diagnosis of the condition. The term arthritis refers to stiffness in the joints. See Answer What is

the treatment for granulomatosis with polyangiitis? Readers Comments 18 Share Your Story Granulomatosis with polyangiitis is a serious disease and without treatment can be fatal within months. Treatment is directed toward stopping the inflammation process by suppressing the immune system.Medications used to treat granulomatosis with

polyangiitis include high-dose cortisone (prednisone) and the immunosuppressive drug cyclophosphamide (Cytoxan). Recent reports also suggest that trimethoprim/sulfamethoxazole (Bactrim) also can be helpful to prevent relapse of disease activity in patients with the condition.Cytoxan that is taken by mouth with prednisone until the disease is in

remission and then switched to methotrexate (Rheumatrex, Trexall) for two years and tapered off has been reported to be effective and less toxic than the traditional long-term Cytoxan treatment.Methotrexate (Rheumatrex, Trexall) has been introduced as a drug for Cytoxan treatment failures. Moreover, it now appears that Cytoxan will not be

necessary in order to maintain long-term remission, and that doctors can convert to the less toxic methotrexate for maintenance.Reports also demonstrate that methotrexate can eventually be tapered off entirely after two years. Azathioprine (Imuran) has also been used as a maintenance medication after Cytoxan.Intravenous immunoglobulin therapy

(IVIG) has been shown to be helpful in treating relapses of granulomatosis with polyangiitis.A newer and more effective treatment for granulomatosis with polyangiitis is rituximab (Rituxan), given intravenously weekly for four weeks in combination with cortisone medication. These new regimens are welcome news for patients with as medical

researchers are searching for better treatments.What is the prognosis for granulomatosis with polyangiitis? The prognosis for granulomatosis with polyangiitis depends on which organs are involved, to what degree they are involved, the duration of the disease, and the response to treatment. Today, with an optimal response to treatment, people with

the condition scan lead normal lives. Medically Reviewed on 5/6/2020 References American College of Rheumatology National Meeting, November 2005, 2006, 2007.
