ANCA Vasculitis Understanding and Treatment Algorithm

ANCA Vasculitis Overview

ANCA vasculitis is a rare, life-threatening autoimmune disease characterized by inflammation and destruction of small blood vessels, which can lead to significant organ damage. The disease primarily affects the kidneys, lungs, upper respiratory tract, skin, nerves, and other organs. ANCA vasculitis is broadly classified into three major subtypes: GPA, MPA, and EGPA, each differing in clinical presentation and organ involvement. The disease occurs when the immune system mistakenly attacks healthy blood vessels, leading to inflammation, reduced blood flow, and tissue damage. If left untreated, ANCA vasculitis can result in severe complications such as kidney failure, pulmonary hemorrhage, and permanent organ dysfunction.

ANCA Vasculitis Diagnosis

The diagnosis of ANCA vasculitis involves a combination of clinical evaluation, laboratory testing, imaging studies, and tissue biopsy to confirm disease subtype and assess organ involvement. Blood tests are commonly used to detect ANCA, including proteinase-3 (PR3-ANCA) and myeloperoxidase (MPO-ANCA), which are key diagnostic markers. Additional laboratory tests may include inflammatory markers, kidney function tests, and urinalysis to evaluate disease severity. Imaging techniques such as CT scans, chest X-rays, and MRI may help identify lung or sinus involvement. In many cases, a tissue biopsy of the kidney, lung, skin, or other affected organs remains the gold standard for confirming vasculitis and determining the extent of vascular inflammation. Early diagnosis is critical to initiating timely treatment and preventing irreversible organ damage.

ANCA Vasculitis Treatment

The treatment of ANCA-associated vasculitis (AAV) focuses on inducing remission, preventing relapse, minimizing organ damage, and reducing long-term treatment-related toxicities. Treatment selection depends on disease subtype (GPA, MPA, or EGPA), severity of organ involvement, and relapse history. In severe or newly diagnosed cases, high-dose corticosteroids are commonly used for rapid inflammation control, although long-term use is limited by complications such as infections, osteoporosis, and metabolic disorders. Immunosuppressive agents such as cyclophosphamide, azathioprine, methotrexate, and mycophenolate mofetil remain important for remission induction and maintenance therapy, particularly in patients requiring long-term disease control.

The treatment landscape has evolved with the adoption of targeted therapies. Rituximab remains a key biologic for GPA and MPA, while Avacopan helps reduce corticosteroid use through C5a receptor inhibition. In EGPA, Mepolizumab has expanded treatment options by targeting IL-5.

Emerging therapies such as Depemokimab (GSK3511294), NS-229, and Iptacopan are expected to further improve long-term remission and provide safer steroid-sparing treatment options. Overall, the market is shifting toward targeted and relapse-preventive therapies.
