Vasculitis in children

What are the signs and symptoms of vasculitis in children?

Symptoms of vasculitis will vary based on which blood vessels are involved and how blood flow to the organs is being affected.

Common symptoms of vasculitis may include:

• Fever
• Fatigue
• Weight loss
• Muscle and joint pain
• Cough
• Shortness of breath
• Purple or red spots on the skin
• Numbness or weakness

How is vasculitis in children diagnosed?

There are several tests to diagnose vasculitis in children. A doctor will go over your child's medical history and perform a physical exam.

Your healthcare provider may also perform one or more of the following tests:

• Blood tests
• Urine tests
• X-rays
• Computerized tomography (CT) scan, a noninvasive test that uses X-rays to create cross-sectional pictures of the body
• Ultrasound, a noninvasive test that uses sound waves to take pictures of the body
• Magnetic resonance imaging (MRI), a noninvasive test that uses magnetic fields to produce images of the body
• Angiogram, a test that uses dye and special X-rays to show blood flowing through the blood vessels
• Biopsy, a test in which a small amount of tissue is surgically removed from a blood vessel and the tissue is then examined under a microscope

Not every child needs all these tests. Your physician will tell you exactly what the next steps are.

What are the causes of vasculitis in children?

In most cases, the exact cause of vasculitis is unknown. It is thought to be an autoimmune disorder, a disease in which the immune system attacks healthy organs or tissue (in this case, the blood vessels).

It can sometimes be triggered by other autoimmune disorders (such as lupus, rheumatoid arthritis or scleroderma), infection, certain blood cancers (such as leukemia or lymphoma), or in reaction to certain medications.

How is vasculitis in children treated?

The severity of your child’s vasculitis and which organs are affected will determine the treatment. The goal of vasculitis treatment is to reduce the inflammation in the affected blood vessels.

Your healthcare provider may recommend one or more of the following treatments:

Medications

Prescription medications are used to either reduce inflammation or kill the cells that cause inflammation. Your healthcare provider may prescribe one or both to treat your child’s vasculitis.

Common medications include:

• Corticosteroids such as prednisone, prednisolone and methylprednisolone help reduce inflammation
• Cytotoxic medicines including azathioprine, methotrexate, and cyclophosphamide destroy the cells that are causing the inflammation

Surgery

In rare cases, surgery may be necessary to bypass blocked vessels
