What is ANCA-Associated Vasculitis?
ANCA-associated vasculitis (AAV) is a group of rare autoimmune diseases that cause inflammation and damage to small blood vessels. The main forms are granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA). Inflammation can affect multiple organs, particularly the kidneys, lungs, upper airways, skin, nerves, and, in some patients, the eyes or gastrointestinal system. AAV is often associated with antibodies called antineutrophil cytoplasmic antibodies (ANCA), although not every patient with AAV is ANCA-positive.
What is the Importance of Timely Treatment?
Early diagnosis and treatment matter because active vasculitis can rapidly damage organs, especially the kidneys and lungs. Severe disease can lead to rapidly progressive kidney failure, pulmonary haemorrhage or other life-threatening complications. Treatment aims to control inflammation, achieve remission and prevent permanent organ damage and relapses. Current guidelines recommend prompt induction therapy for organ- or life-threatening disease.
What are the Common Symptoms of ANCA-Associated Vasculitis?
- Persistent fatigue and weakness
- Fever or unexplained weight loss
- Joint and muscle pain
- Skin rashes or purpura, particularly on the legs
- Sinusitis, nasal congestion or recurrent nose problems
- Nosebleeds or nasal crusting
- Cough or shortness of breath
- Coughing up blood in severe lung involvement
- Blood or protein in the urine
- Swelling of the legs or feet
- Reduced kidney function
- Numbness, tingling or weakness due to nerve involvement
- Eye redness, pain or vision changes
- Gastrointestinal pain or other organ-specific symptoms
Causes and Risk Factors of ANCA-Associated Vasculitis
Causes
- The exact cause of ANCA-associated vasculitis is not fully understood. It is believed to result from an abnormal immune response in which activated immune cells and, in many patients, ANCA antibodies contribute to inflammation and injury of small blood vessels.
- Genetic susceptibility and environmental or infectious triggers may contribute to disease development.
Risk Factors
- Genetic susceptibility
- Family history of autoimmune or vasculitic disease
- Exposure to certain environmental or occupational factors
- Some infections or medications, particularly in selected forms of ANCA-positive vasculitis
- Increasing age for certain AAV subtypes
Latest Research and Technologies in the Treatment of ANCA-Associated Vasculitis in Turkey
- Treatment of AAV is evolving toward individualised, steroid-sparing and relapse-aware approaches. Lower-dose glucocorticoid regimens and the complement inhibitor avacopan have expanded steroid-sparing strategies for selected patients. Plasma exchange may also be considered in specific patients with severe kidney involvement or other high-risk presentations. Research is also investigating biomarkers, ANCA characteristics, complement pathways and immune-cell mechanisms to better predict disease activity and relapse. Advanced kidney assessment, high-resolution chest imaging, bronchoscopy when indicated, and kidney biopsy can help determine the extent of organ involvement and guide treatment.
Treatment options for ANCA-Associated Vasculitis
Plasmapheresis : Plasma exchange may be considered for selected patients with severe kidney disease or specific high-risk presentations, after assessing potential benefits and risks.

Remission-Induction Therapy: Initial treatment aims to control inflammation quickly and prevent further organ damage. Depending on disease severity and the organs affected, this may involve immune-suppressing treatment, steroid-based therapy or targeted approaches.
- Clinical assessment:
- Medical and Physical Evaluation: Review a detailed medical and medication history and perform a physical examination to identify systemic and organ-specific manifestations. Assessment may include symptoms and signs involving the kidneys, lungs, nerves, skin, eyes and ENT system, helping determine the pattern and severity of disease.
- Kidney and Laboratory Assessment: Assess kidney function using serum creatinine and estimated GFR, along with urinalysis to detect blood or protein in the urine. Complete blood count, inflammatory markers, liver function tests and other organ-function tests may also be performed when clinically indicated.
- ANCA Testing: Blood testing for antineutrophil cytoplasmic antibodies (ANCA), can support the diagnosis and provide information about the AAV subtype. However, interpret ANCA results alongside clinical findings because a positive result does not confirm AAV, and some patients with AAV may be ANCA-negative.
- Tissue Biopsy: Kidney or other tissue biopsy may be recommended when the diagnosis remains uncertain or when confirmation and assessment of organ damage are important. In suspected kidney involvement, a kidney biopsy can help identify active vasculitic inflammation, chronic scarring and the extent and pattern of kidney injury.
- Imaging Tests:
- Chest X-ray: May identify lung infiltrates, nodules or other pulmonary abnormalities.
- High-resolution chest CT: Provides detailed assessment of pulmonary nodules, infiltrates, haemorrhage, or interstitial changes.
- CT of the Sinuses: May be used in GPA when persistent upper-airway or sinus involvement is suspected.
- Kidney Ultrasound: Helps assess kidney size and exclude structural causes of kidney dysfunction.
- MRI: May be used when neurological, orbital or other organ involvement requires detailed imaging.
- Echocardiography: Consider when cardiac involvement or pulmonary hypertension is suspected.
MediRehab (a chain of Rehab centres, part of MediGence) provides comprehensive tele-rehabilitation services designed to support ANCA-Associated Vasculitis patients in Turkey. These services include:
- Physiotherapy: Helps maintain muscle strength, mobility, balance and endurance in patients affected by weakness, nerve involvement or prolonged illness.
- Occupational Therapy: Supports independence with daily activities when fatigue, weakness, neuropathy or joint problems affect function.
- Respiratory Rehabilitation: Selected patients with significant lung involvement may benefit from breathing exercises, pulmonary rehabilitation and monitored physical activity.
- Neurological Rehabilitation: Patients with peripheral nerve involvement may require gait training, balance exercises and targeted rehabilitation.
- Medicines for ANCA-associated vasculitis aim to suppress abnormal immune activity, induce remission and prevent relapse. Doctors may prescribe additional medicines to prevent infection, control blood pressure, manage kidney complications, protect bones, or address other treatment-related risks. Medication selection and dosing require close specialist monitoring because immunosuppressive therapy can increase the risk of infections and other adverse effects.
