Vasculitis – Diagnosis and Treatment

ByJanis Updated

Diagnosis

Doctors gather information from a patient’s symptoms and perform a physical exam to find out if someone has vasculitis. They look for clinical features that suggest blood vessel inflammation.

Vasculitis can be hard to diagnose because symptoms like fatigue, fever, or skin changes often look like other diseases.

Doctors use several tools for diagnosis:

Method What It Detects
Blood tests Inflammation, anemia, ANCA antibodies
Urinalysis Kidney involvement
Imaging Changes in vessel size, vessel damage, aneurysm
Angiogram Blockages, abnormal vessel structure
Biopsy Direct tissue signs of vasculitis.
  • Blood Tests:
    • C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) help detect inflammation in the body.
    • Complete blood count (CBC) checks for anemia or low blood cells, which sometimes happen with vasculitis.
    • Antineutrophil cytoplasmic antibodies (ANCA) help identify certain types, especially ANCA-associated vasculitis.

  • Urinalysis: This test checks for blood or protein in urine. These findings might show kidney involvement.

  • Imaging Tests: Ultrasound, CT, MRI, and PET scans show changes in arteries, veins, and capillaries. These images help reveal aneurysms, ischemia, or areas of narrowed or inflamed blood vessels.

  • Angiogram: Doctors use this special x-ray with dye to map blood flow and spot abnormal areas in large or medium vessels.
  • Tissue Biopsy: Doctors take a small sample from an affected organ, such as skin, kidney, or artery. Under a microscope, this tissue may show granulomas or necrotizing vasculitis.

Doctors classify the type of vasculitis based on which blood vessels are involved and test results. This approach helps separate primary vasculitides from other causes and guides treatment.

Treatment

Medicines Used to Reduce Inflammation

Doctors often start treatment with medicines that lower inflammation and help prevent organ damage. Corticosteroids are commonly used first.

Doctors prefer lower doses when possible, since side effects can include diabetes, weight gain, and weaker bones, especially with long-term use.

Doctors often add other drugs to manage the disease and reduce steroid use. These may include:

  • Antimetabolites: Commonly used for microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA).
  • Alkylating Agents: Sometimes used for severe forms like polyarteritis nodosa.
  • Purine Analogs: Help maintain disease control during long-term therapy.
  • Monoclonal Antibodies: May be used for specific cases, such as giant cell arteritis or severe systemic vasculitis.
  • Therapeutic Apheresis (Plasma Exchange): In severe cases, especially when vital organs like the kidneys are at risk, this procedure may help remove harmful substances from the blood.

Doctors choose the drug and treatment duration based on the type of vasculitis, which organs are affected, and the patient’s medical history.

Operations for Vessel Problems

Doctors may perform surgery if vasculitis causes serious blood vessel problems. If a blood vessel wall develops an aneurysm, surgeons repair it to avoid complications.

Sometimes, blocked arteries limit blood flow to organs. In these cases, doctors may open or bypass the blockage to restore normal circulation.

Doctors consider these options mainly in rare, severe cases or when medicines are not enough to prevent organ damage.

Strategies for Daily Living and Finding Support

Managing vasculitis involves more than treating symptoms. Learning ways to handle the condition and its impact on daily life can help.

Staying informed about vasculitis and its treatment helps people feel more in control. People should report any new or unusual health changes to healthcare providers, since medications can affect the immune system and may increase the risk of infections.

Following the treatment plan helps reach and maintain remission. This usually means having regular checkups, blood pressure monitoring, and lab tests.

Eating well can help with side effects from medicines, such as bone thinning, high blood pressure, or increased blood sugar. A balanced diet includes fresh fruits, vegetables, whole grains, low-fat dairy foods, and lean protein.

People using corticosteroids might need calcium or vitamin D supplements. Healthcare professionals can give specific recommendations.

Healthy Habits Benefits
Eating nutritious foods Supports overall health, lowers side effects.
Regular exercise Improves strength, mood, and heart health.
Staying updated on vaccines Reduces chances of infection.

Vaccinations are important for those with vasculitis, especially because the immune system may be weaker due to treatment. Vaccines for the flu, pneumonia, shingles, and COVID-19 are often suggested.

Each person should check with their healthcare professional to see which vaccines are right for them. Physical activity helps people manage some side effects of medicine and can also lift mood.

Aerobic exercise almost every day, such as walking, can help protect the bones, reduce the risk of high blood pressure and diabetes, support a healthy heart and lungs, and improve emotional well-being.

Support from others matters. Family, friends, and support groups can offer encouragement and understanding. Talking with others who have vasculitis or a similar autoimmune disease can help with day-to-day challenges.

Getting Ready for Your Doctor Visit

Steps You Can Take Before the Appointment

  • Find Out if You Need to Do Anything First: Call ahead to see if you need to change your diet, fast, or stop any medicines before your visit.
  • Send Needed Test Results: Ask your main doctor to forward imaging or biopsy results to your specialist. This helps avoid delays and gives your new doctor a clear picture of your health.
  • Write Down All Your Symptoms: Note when symptoms like fever, fatigue, joint pain, weight loss, anemia, asthma, or other issues started. Also, write if you’ve noticed things like leukocytosis (high white blood cell count) or eosinophilia.

  • List Your Medical Background: Include past and current health problems, major stresses, and all medicines, vitamins, or supplements with doses.

  • Bring Support: Bring a friend or family member if possible, as two people can remember more than one.

  • Prepare Your Questions: Think about what you want to ask. Here are some common questions:

    • What type of illness do I have?

    • What is causing my symptoms?

    • Is this condition short-term or ongoing?

    • Do I need to see a specialist?
    • What treatments are available?
    • How can I manage this illness along with my other health problems?

What Your Doctor Might Ask You

  • Are your symptoms steady, or do they come and go?
  • How strong or severe are they?
  • What helps these symptoms get better?
  • What seems to make them worse?

Doctors focus on symptoms like fatigue, fever, joint pain, trouble breathing, or weight loss. They ask detailed questions to learn more about each symptom’s pattern.

Try to answer as honestly and fully as you can. If you need to see several different specialists, like a rheumatologist for joints or a pulmonologist for asthma, keep their instructions and questions organized.

Staying organized can make your visits easier and help your healthcare team create a complete treatment plan.
