Vasculitis

What is Vasculitis?
Vasculitis refers to a group of rare autoimmune conditions that cause inflammation of the blood vessels. This inflammation can lead to narrowing, weakening, or even blockage of the vessels, disrupting normal blood flow to organs and tissues. Vasculitis can affect any organ system, which is why early diagnosis and expert management are critical.

Common Types We Treat Include:

• Giant Cell Arteritis (GCA) – Often affects the arteries in the head and neck; may cause headaches, scalp tenderness, and vision changes.

• Granulomatosis with Polyangiitis (GPA) – Affects small-to-medium vessels, typically involving the respiratory tract and kidneys.

• Microscopic Polyangiitis (MPA) – Can involve the kidneys, lungs, skin, and nervous system.

• Takayasu Arteritis – Primarily affects large vessels like the aorta and its branches; more common in younger individuals.

• Polyarteritis Nodosa (PAN) – Affects medium-sized arteries and can involve muscles, joints, skin, and gastrointestinal system.

Symptoms May Include:

• Fatigue, fever, or weight loss

• Skin rashes or ulcers

• Joint and muscle pain

• Shortness of breath or chest pain

• Nerve symptoms such as tingling or weakness

• Headaches or vision disturbances

How We Diagnose Vasculitis:
Diagnosis involves a thorough clinical evaluation along with specialized lab work, imaging (such as CT/MRI or ultrasound), and in some cases, biopsy of affected tissues. Because vasculitis can mimic other conditions, our approach focuses on accurate identification to avoid delays in care.

Treatment Approach:
Treatment is personalized based on the type and severity of vasculitis and which organs are affected. Our care typically includes:

• Immunosuppressive medications 

• Biologic therapies for refractory or relapsing cases

• Close monitoring with labs and imaging to track disease activity

• Infusion therapy available in-clinic when needed for more advanced care
