Can Lupus Cause Hearing Issues?
Systemic lupus erythematosus, also called lupus, is a disease where the body's defense system makes a mistake. Instead of only fighting germs, it attacks healthy parts of the body.
Many people do not know that lupus can also affect the ears. It can cause hearing problems. Some people may have mild hearing loss, while others may have more serious issues. These problems can happen because of lupus itself or sometimes because of the medicines used to treat it.
How Does Lupus Affect Your Ears?
Doctors do not fully understand how lupus causes hearing problems. However, experts have suggested several possible reasons for this link.
Reduced Blood Flow:
If enough blood does not reach the inner ear, it does not get enough oxygen. Without enough oxygen, the ear tissues can become damaged. This damage can lead to hearing loss.
Inflammation of the blood vessels can also block the tiny blood vessels in the ear. When this happens, it may cause temporary or even permanent hearing problems in people with systemic lupus erythematosus.
Autoimmune Inner Ear Disease (AIED):
In lupus, the immune system makes a mistake and attacks the body’s own tissues. Sometimes, it can attack the inner ear.
When this happens, the inner ear can become swollen and filled with fluid. The tiny cells that help you hear can get damaged. Because of this, a person may have hearing loss, ringing in the ears, or feel dizzy.
If treatment is delayed, the hearing damage may slowly become worse over time.
Side Effects of Medicines
Some medicines used to treat lupus can affect hearing. Hydroxychloroquine (used for lupus) may sometimes harm the inner ear. Doctors usually monitor patients carefully to reduce this risk.
Brain and Nerve Involvement:
Lupus can also affect the brain and nerves. If the parts of the brain that process sound are affected, a person may hear sounds but have trouble understanding them, especially in noisy places.
Immune Complex Build-Up:
In lupus, harmful immune particles can build up in different parts of the body, including the inner ear. This can cause inflammation and damage. It may lead to sudden hearing loss, ringing in the ears, or balance problems.
Inflammatory Chemicals (Cytokines):
Lupus increases certain inflammatory chemicals in the body. High levels of these chemicals can damage tissues, including the delicate parts of the inner ear.
What Are the Signs of Hearing Problems in Lupus?
Hearing problems in lupus can show up in different ways. Because lupus affects people differently, ear-related symptoms can also vary.
Hearing Loss:
Hearing loss is one of the most common ear problems in people with lupus. It can appear in different forms:
-
Sudden Hearing Loss: Hearing may suddenly decrease, usually in one ear. This can happen quickly and is considered a medical emergency.
-
Gradual (Progressive) Hearing Loss: More commonly, hearing may slowly worsen over time. It can affect one or both ears.
-
Conductive Hearing Loss: This is less common. It happens when sound cannot properly travel through the outer or middle ear. It may be caused by swelling or fluid buildup.
-
Sensorineural Hearing Loss: This is more common in lupus and occurs when there is damage to the inner ear or the hearing nerve.
Ringing in the Ears (Tinnitus):
Another common ear issue in lupus is tinnitus, which means hearing sounds like ringing, buzzing, or hissing when no external sound is present.
Types of Tinnitus
-
Occasional or Constant: It may come and go or be there all the time.
-
In One or Both Ears: It can affect one ear or both.
-
High- or Low-Pitched: The sound may be sharp and high or deep and low, depending on the cause.
What Is the Treatment for Hearing Disorders in Lupus?
Treating hearing disorders in lupus patients involves a comprehensive approach that addresses the underlying lupus and the specific auditory symptoms.
Corticosteroids: Corticosteroids are a cornerstone in treating acute hearing loss in lupus patients. They help reduce immune response and inflammation.
Immunosuppressants: These drugs are used to control the underlying autoimmune activity. This prevents or reduces the recurrence of auditory symptoms:
-
Methotrexate: Often prescribed for its effectiveness in reducing autoimmune activity and inflammation.
-
Azathioprine: Another commonly used immunosuppressant that is beneficial for long-term management.
-
Cyclophosphamide and Mycophenolate Mofetil: These are used for severe disease or those who do not respond to first-line immunosuppressants.
Antivirals and Antibiotics: Infections can exacerbate hearing loss in lupus patients, necessitating appropriate antimicrobial treatment:
-
Antibiotics: Used for bacterial infections of the ear or respiratory tract, which can impact hearing.
-
Antivirals: Employed in cases of viral infections, such as herpes zoster oticus (Ramsay Hunt syndrome), which can cause hearing loss and vertigo.
-
Prompt Treatment: Early identification and treatment of infections are critical to preventing permanent auditory damage.
Therapies for Tinnitus and Vertigo: Specialized therapies can help manage tinnitus and vertigo, improving the patient's ability to cope with these symptoms:
-
Cognitive Behavioral Therapy (CBT): This therapy helps patients manage the psychological impact of tinnitus by changing their response to persistent sounds.
-
Vestibular Rehabilitation: It is designed to alleviate vertigo and balance issues.
-
Sound Therapy: In this, external sounds are used to mask tinnitus and make it less noticeable. This can include white noise machines or hearing aids equipped with masking features.
Hearing Aids
For people with permanent hearing loss due to lupus, hearing aids can greatly improve communication and overall quality of life. An audiologist will perform hearing tests to choose the most suitable hearing aid and ensure it fits comfortably and works properly.
Types of Hearing Aids:
Different options are available based on the level of hearing loss and personal preference:
-
Behind-the-ear (BTE).
-
In-the-ear (ITE).
-
Completely-in-canal (CIC).
Regular follow-up visits must be done to fine-tune the hearing aids for the best sound quality and to check for cleaning, repairs, or battery changes.
Conclusion
In short, hearing problems in lupus can occur for many reasons, including inflammation, reduced blood flow, medication side effects, or nerve damage. These hearing issues can be complex and may require careful evaluation and correct treatment.
If you notice any changes in your hearing or any ear-related issues, consult an experienced ear specialist (ENT doctor) promptly.
Key Takeaways
