In some cases, especially when vasculitis affects the inner ear and balance, the following may be recommended: Vestibular physiotherapy to treat dizziness or vertigo if the inner ear is involved. Blood pressure control if vasculitis leads to kidney or cardiovascular issues that indirectly affect ear circulation.

Vasculitis and hearing: tinnitus, vertigo, and hearing loss

Q: Hearing Loss

Inflammation of blood vessels in the middle or inner ear can damage auditory structures, leading to hearing loss, which may be gradual or sudden.

Q: Vascular tinnitus

Insufficient blood flow may cause a persistent noise sensation, often present when vasculitis affects the areas responsible for hearing.

Q: Ear pain

Inflammation in the ear's blood vessels can cause pain or discomfort, sometimes accompanied by a sensation of pressure in the ear.

Q: Nosebleeds

Although not exclusive to the ear, vasculitis in nearby areas like the nose and sinuses may be related to frequent nosebleeds, which can affect the middle ear.

What Is Vasculitis?

Vasculitis is an autoimmune disease that causes inflammation of blood vessels (arteries, veins, and capillaries), which can affect various organs, including the ears. This inflammation can reduce blood flow to the tissues, leading to damage that, in some cases, may result in severe complications or disability. There are several types of vasculitis, most of which are rare, but some can be serious if not treated properly.

What are the causes of vasculitis?

Vasculitis has various causes, although they are not always clear. In many cases, it is due to an autoimmune reaction where the immune system mistakenly attacks the blood vessels. It can also be triggered by infections, particularly viral ones like hepatitis B or C, which cause an inflammatory immune response.

Certain foods can also worsen vasculitis by increasing inflammation, such as refined sugars, trans fats, processed foods, dairy, and gluten in sensitive individuals. Alcohol and processed meats may exacerbate symptoms, as well as specific allergens (e.g., nuts, shellfish) and nightshade vegetables (e.g., tomatoes, potatoes) for some people. An anti-inflammatory diet and keeping a food diary can help identify and reduce triggers.

Certain medications, such as some antibiotics and anti-inflammatory drugs, may cause vasculitis as a side effect. Additionally, it is associated with chronic autoimmune diseases like lupus or rheumatoid arthritis, and certain cancers that affect the immune system. Although vasculitis is not hereditary, some individuals have a genetic predisposition that increases the risk. Environmental factors such as smoking or exposure to toxins may also contribute to its development.

Symptoms of Vasculitis

Vasculitis presents with a variety of symptoms that depend on the specific type, the affected blood vessels, and the involved organs.

Common symptoms may include:

Fever
Fatigue
Muscle and joint pain
Weight loss
Night sweats

When vasculitis affects specific organs, additional symptoms may arise, such as:

Skin rashes
Difficulty breathing
Headaches
Confusion
Nosebleeds
Hearing problems
Abdominal pain
Leg swelling

In more severe cases, complications can affect the heart, kidneys, and nervous system. Since this disease can impact vital organs, early diagnosis is essential to prevent complications and start appropriate treatment.

Effects of Vasculitis on the middle ear and hearing

Vasculitis can impact the middle ear by compromising the blood flow to this area, leading to inflammation and damage to the tissues of the auditory system. When the blood vessels supplying the middle and inner ear become inflamed, the supply of oxygen and nutrients is reduced, causing damage to structures responsible for hearing and balance.

In particular, certain types of vasculitis, such as granulomatosis with polyangiitis (GPA) or Cogan's syndrome, tend to affect the auditory area, leading to various symptoms.

Symptoms of Vasculitis in the ear

The symptoms of vasculitis in the ear may occur when inflammation affects the blood vessels supplying the middle and inner ear. The reduced blood flow can damage the structures responsible for hearing and balance.

Common symptoms of vasculitis in the ear include:

Hearing Loss

Inflammation of blood vessels in the middle or inner ear can damage auditory structures, leading to hearing loss, which may be gradual or sudden.

Vascular tinnitus

Insufficient blood flow may cause a persistent noise sensation, often present when vasculitis affects the areas responsible for hearing.

Vascular vertigo and dizziness

Vasculitis affecting the inner ear, which is linked to balance, may result in dizziness, instability, or vertigo.

Ear pain

Inflammation in the ear's blood vessels can cause pain or discomfort, sometimes accompanied by a sensation of pressure in the ear.

Nosebleeds

Although not exclusive to the ear, vasculitis in nearby areas like the nose and sinuses may be related to frequent nosebleeds, which can affect the middle ear.

Treatment of Vasculitis

Since vasculitis can impact blood flow to the inner and middle ear, the primary aim of treatment is to reduce inflammation, restore proper circulation, and prevent permanent damage.

Below are common approaches to treating vasculitis in the ear:

Immunosuppressive medications

As vasculitis is often an autoimmune condition, immunosuppressive drugs are essential for controlling inflammation.

Commonly used medications include:

Corticosteroids (like prednisone), which quickly reduce inflammation and control acute symptoms of vasculitis
Immunosuppressants (like cyclophosphamide, azathioprine, or methotrexate), which help suppress the immune system and prevent chronic inflammation in blood vessels.

Treatment of the underlying cause

If vasculitis is caused by an infection, such as hepatitis, or by the use of certain medications, it is important to address the underlying cause with antibiotics or antivirals for related infections, or by discontinuing any drugs that may be triggering the vasculitis reaction.

Treatment of specific ear symptoms

For specific auditory symptoms like hearing loss or tinnitus, various strategies can help alleviate symptoms while addressing the underlying cause:

Hearing aids or assistive listening devices for significant hearing loss.
Tinnitus treatments such as sound therapy or devices that help reduce the perception of ringing in the ears.

Additional therapies

In some cases, especially when vasculitis affects the inner ear and balance, the following may be recommended:

Vestibular physiotherapy to treat dizziness or vertigo if the inner ear is involved.
Blood pressure control if vasculitis leads to kidney or cardiovascular issues that indirectly affect ear circulation.

Regular monitoring and follow-up

Vasculitis requires ongoing monitoring to assess the response to treatment and adjust medication dosages. Regular examinations, including auditory tests, may be needed to detect any hearing deterioration and ensure the treatment is effective

Diagnosis of Vasculitis in the ear

Diagnosing vasculitis in the ear usually involves a combination of medical tests:

Medical history and physical examination: the doctor assesses symptoms and checks for signs of inflammation.
Audiometry and hearing tests: to detect and measure the degree of hearing loss.
Imaging (CT or MRI scans): these tests help visualise inflammation and damage to the ear structures and surrounding areas.
Biopsy (in severe cases): a biopsy may be performed on the affected blood vessels to confirm the presence of vasculitis.
Blood tests: these check for markers of inflammation and specific antibodies associated with autoimmune diseases.

Cogan's syndrome and vasculitis

Cogan's syndrome is a rare disease that mainly affects the eyes and ears, causing inflammation and damage in these areas.

It is characterised by a combination of two main symptoms: keratitis (inflammation of the cornea in the eyes) and vertigo or hearing loss. It is considered a systemic vasculitis because it involves inflammation of the blood vessels, affecting various parts of the body, particularly the inner ear.

In this condition, the inflammation of the blood vessels supplying the eyes and ears is the main cause of symptoms such as hearing loss, vertigo, and vision problems.
