Meniere's disease might be an autoimmune condition?

Area of Science:

• Otolaryngology
• Immunology
• Genetics

Background:

• Meniere's disease presents with vertigo, hearing loss, tinnitus, and aural pressure.
• The exact cause and progression (pathogenesis) of Meniere's disease are not fully understood.
• Current research explores viral infections and immune system involvement in Meniere's disease.

Purpose of the Study:

• To synthesize current knowledge on Meniere's disease pathogenesis.
• To investigate viral and immune-mediated mechanisms.
• To correlate pathogenesis with pharmacotherapy strategies.

Main Methods:

• Systematic review of publications from 1861 to 2011.
• Analysis focused on aetiopathogenesis, molecular biology, genetics, and histopathology.
• Evaluation of proposed causal theories and treatment responses.

Main Results:

• Meniere's disease pathogenesis is unknown; viral and immune mechanisms are proposed.
• Approximately 33% of cases suggest an autoimmune origin, though mechanisms are unclear.
• Steroid treatment shows high responsiveness, potentially reversing inner ear damage.

Conclusions:

• The immune response in Meniere's disease targets inner ear antigens.
• Antiviral approaches have largely replaced older surgical methods.
• Emerging therapies include etanercept, antithrombotic medications for antiphospholipid syndrome, and gene therapy for hair cell regeneration.
