Summary
This study investigated viral infections in 44 vestibular neuronitis patients. Significant antibody titer changes in 17 cases suggest viruses like Epstein-Barr virus (EBV) may trigger vertigo.
Area of Science:
- Neurology
- Virology
- Immunology
Background:
- Vestibular neuronitis is an inner ear disorder causing vertigo.
- Its exact cause and pathogenesis remain unclear.
- Viral infections are suspected contributors.
Purpose of the Study:
- To investigate the role of viral infections in the pathogenesis of vestibular neuronitis.
- To analyze serum viral antibody titers in patients diagnosed with vestibular neuronitis.
Main Methods:
- A serovirological study was conducted on 44 patients diagnosed with vestibular neuronitis.
- Paired serum samples were collected and analyzed for viral antibody titers.
- Significant changes in antibody titers were assessed.
Main Results:
- Of 36 patients with paired sera, 17 showed significant changes in viral antibody titers.
- Detected viruses included herpes simplex virus (HSV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), rubella, adenovirus, and influenza A and B.
- Epstein-Barr virus (EBV) showed the highest association, with 7 cases exhibiting significant titer changes.
Conclusions:
- The findings suggest that viral infections play a significant role in the onset of vertigo in patients with vestibular neuronitis.
- Specific viruses, particularly EBV, are implicated as potential triggers.
- Further research is warranted to elucidate the precise mechanisms of viral-induced vestibular neuronitis.
