What Are the Common Causes and Risk Factors?

Understanding vasculitis caregiver guide seniors is important for seniors and their caregivers. necrotizing vasculitis may be the primary condition such as in people with

polyarteritis nodosa

or

granulomatosis with ANCA associated vasculitis

(formerly called Wegener granulomatosis). In other cases, the vasculitis may occur as part of another disorder, such as systemic lupus erythematosus or hepatitis C.

The cause of the inflammation is unknown. It is likely related to

autoimmune

factors. The wall of the blood vessel may scar and thicken or die (become

necrotic

). The blood vessel may close, interrupting blood flow to the tissues it supplies. The lack of blood flow will cause the tissues to die. Sometimes the blood vessel may break and bleed (rupture).

Necrotizing vasculitis may affect blood vessels in any part of the body. Therefore, it can cause problems in the skin, brain, lungs, intestines, kidney, brain, joints or any other organ.

What Are the Symptoms and Warning Signs?

Fever,

chills

,

fatigue

,

arthritis

, or weight loss may be the only symptoms at first. However, symptoms may be in almost any part of the body.

Skin:

  • Red or purple colored bumps on the legs, hands or other parts of the body
  • Bluish color to the fingers and toes
  • Signs of tissue death due to lack of oxygen such as pain, redness, darkening of skin tone, and ulcers that do not heal

Muscles and joints:

  • Joint pain

  • Leg pain
  • Muscle weakness

Brain and nervous system:

  • Pain,

    numbness

    , tingling in an arm, leg, or other body area

  • Weakness of an arm, leg, or other body area
  • Pupils that are different sizes
  • Eyelid drooping

  • Swallowing difficulty

  • Speech impairment

  • Movement difficulty

Lungs and respiratory tract:

  • Cough

  • Shortness of breath

  • Sinus congestion and pain
  • Coughing up blood or bleeding from the nose

Other symptoms include:

  • Abdominal pain

  • Blood in the urine

    or

    stools

  • Hoarseness or changing voice
  • Chest pain from damage of the arteries that supply the heart (coronary arteries)
📖 What Are Exams and Tests?

What Are Exams and Tests?

The health care provider will do a complete physical exam. A nervous system (neurological) exam may show signs of nerve damage.

Tests that may be done include:

  • Complete blood count

  • Comprehensive metabolic panel

  • Chest x-ray

  • C-reactive protein test

  • Erythrocyte sedimentation rate

  • Hepatitis

    blood test

  • Urinalysis

  • Blood test for antibodies against neutrophils (ANCA antibodies) or nuclear antigens (ANA)
  • Blood test for cryoglobulins
  • Blood test for

    complement

    levels

  • Imaging studies such as

    angiogram

    , ultrasound, computed tomography (CT) scan, or magnetic resonance imaging (MRI)

  • Biopsy

    of the skin, muscle, organ tissue, or

    nerve

📖 How Is It Treated?

How Is It Treated?

Corticosteroids are given in most cases. The dose will depend on how bad the condition is.

Other medicines that suppress the immune system may reduce inflammation of the blood vessels. These include azathioprine, methotrexate, and mycophenolate. These medicines are often used along with corticosteroids. This combination makes it possible to control the disease with a lower dose of corticosteroids.

For severe disease, cyclophosphamide (Cytoxan) has been used for many years. However, rituximab (Rituxan) is equally effective and is less toxic.

Recently, tocilizumab (Actemra) was shown to be effective for giant cell arteritis so the dose of corticosteroids could be reduced.

📖 What Is Outlook (Prognosis)?

What Is Outlook (Prognosis)?

Necrotizing vasculitis can be serious and life-threatening disease. The outcome depends on the location of the vasculitis and the severity of tissue damage. Complications may occur from the disease and from the medicines. Most forms of necrotizing vasculitis require long-term follow-up and treatment.

📖 What Are Possible Complications?

What Are Possible Complications?

Complications may include:

  • Permanent damage to the structure or function of the affected area

  • Secondary infections

    of necrotic tissues

  • Side effects from medicines used for treatment
📖 When to Contact a Medical Professional?

When to Contact a Medical Professional?

Contact your provider if you have symptoms of necrotizing vasculitis.

Emergency symptoms include:

  • Problems in more than one part of the body such as stroke, arthritis, severe skin rash, abdominal pain or coughing up blood
  • Changes in pupil size
  • Loss of function of an arm, leg, or other body part
  • Speech problems
  • Swallowing difficulty
  • Weakness
  • Severe abdominal pain
