Hearing impairment in meningococcal meningitis.
Scandinavian Journal of Infectious Diseases
|January 1, 1979
Summary
Meningococcal meningitis can cause hearing loss, affecting 5.8% of patients. Younger individuals, females, and severe cases showed higher incidence, with early treatment potentially increasing risk.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Epidemiology
Background:
- Meningococcal meningitis is a serious infection with potential neurological sequelae.
- Hearing impairment is a recognized but not fully understood complication of meningitis.
Purpose of the Study:
- To investigate the incidence of hearing affection following meningococcal meningitis.
- To determine the relationship between hearing impairment and patient/disease factors.
Main Methods:
- Retrospective study of 775 patients diagnosed with meningococcal meningitis.
- Data collected on age, sex, disease severity, duration, and treatment timing.
- Incidence of hearing impairment was calculated and analyzed.
Main Results:
- Overall incidence of hearing impairment was 5.8%.
- Higher incidence observed in younger age groups, females, and severe meningitis cases.
- Early initiation of specific therapy correlated with increased hearing impairment.
Conclusions:
- Hearing impairment is a significant sequel of meningococcal meningitis.
- Risk factors include young age, female sex, disease severity, and potentially early treatment.
- Further research into the mechanisms of meningitis-induced hearing loss is warranted.
