Granulomatosis with Polyangiitis (GPA), formerly known as Wegener’s Granulomatosis, is a rare autoimmune disease characterized by inflammation of small- to medium-sized blood vessels (vasculitis) and the formation of granulomas (clusters of immune cells) in organs such as the nose, sinuses, lungs, and kidneys. In very simple English, this means the body’s defense system mistakenly attacks its own blood vessels, causing redness, swelling, and tissue damage. Over time, this can lead to symptoms ranging from chronic sinus infections and nosebleeds to shortness of breath and kidney failure.
GPA affects about 3 cases per 100,000 people worldwide. It typically appears in adults aged 40–60 but can occur at any age. Early diagnosis and treatment are essential to prevent irreversible organ damage. This article offers evidence-based, plain-English explanations of GPA’s key aspects, along with comprehensive strategies for management and lifestyle support.
Pathophysiology
Autoimmunity: The body’s immune system creates antibodies called ANCA (anti-neutrophil cytoplasmic antibodies) that stick to white blood cells, causing them to attack blood vessel walls.
Vasculitis: The attacked blood vessels become red, swollen, and leaky, leading to poor blood flow and oxygen delivery.
Granuloma Formation: Immune cells cluster together in tissues, forming lumps (granulomas) that further damage organs like the lungs and sinuses.
Granulomatosis with Polyangiitis (GPA) is a rare autoimmune disease in which the body’s defense system mistakenly attacks small blood vessels. This leads to two hallmark problems:
Necrotizing vasculitis – inflammation that destroys vessel walls, cutting off blood supply.
Granuloma formation – clusters of immune cells that form lumps in tissues.
GPA most often affects the nose, sinuses, lungs, and kidneys, but it can strike any organ.
“Granulomatosis with polyangiitis is characterized by necrotizing granulomas of the respiratory tract and necrotizing vasculitis affecting small- to medium-sized vessels.” Frontiers
“GPA is one of the ANCA-associated vasculitides, with a spectrum of presentations broadly divided into limited or severe disease.” Medscape
Types of GPA
Researchers group GPA into three broad types based on how many organs are involved and how severe the disease is:
Limited GPA
Only the respiratory tract (nose, sinuses, lungs) is affected.
There is no kidney involvement.
Symptoms tend to be milder and may progress slowly.
Medscape
Classical (Systemic) GPA
Involves the full “triad” of upper airway, lung, and kidney disease.
Patients may have sinus pain, cough with blood, and kidney inflammation all at once.
This form is often more aggressive and requires prompt treatment.
Radiopaedia
Superficial or Cutaneous GPA
Primarily affects the skin, forming tender nodules or ulcers.
May occur alone or alongside limited or systemic disease.
