[Fluctuant perception hearing loss after hepatitis B vaccine]
Summary
Hepatitis B vaccination (Engerix B) was linked to temporary tinnitus and fluctuating sensorineural hearing loss in a physician. Symptoms resolved after six months, suggesting a transient vaccine side effect.
Area of Science:
- Otolaryngology
- Vaccinology
- Immunology
Background:
- Hepatitis B vaccination is crucial for preventing viral infection.
- Adverse events following immunization (AEFIs) require careful monitoring and reporting.
- Sensorineural hearing loss and tinnitus are significant auditory symptoms.
Observation:
- A 42-year-old physician received the first dose of Engerix B hepatitis B vaccine.
- Temporary tinnitus occurred after the first dose.
- Fluctuating sensorineural hearing loss and tinnitus emerged hours after the second dose.
Findings:
- Auditory thresholds ranged from 0 dBHL to 45 dBHL for low frequencies (<1.5 kHz).
- The hearing loss and tinnitus exhibited a fluctuating pattern.
- Complete resolution of auditory symptoms was observed after a 6-month period.
Implications:
- This case highlights a potential, albeit temporary, ototoxic effect of the Engerix B vaccine.
- Further investigation into vaccine-induced auditory disturbances is warranted.
- Physicians should be aware of potential auditory side effects following hepatitis B vaccination.
