Significant sequelae after bacterial meningitis in Niger: a cohort study.

Area of Science:

• Neurology
• Public Health
• Epidemiology

Background:

• Acute bacterial meningitis leads to significant mortality and neuropsychological sequelae.
• The meningitis belt, particularly Sahelian Africa, bears a high global burden of meningitis cases.
• Niger faces yearly epidemics with limited rehabilitation resources and unaffordable hearing aids.

Purpose of the Study:

• To estimate the frequency of neuropsychological sequelae following acute bacterial meningitis.
• To assess the long-term impact of meningitis on neurological function in Niger.

Main Methods:

• A cohort study design comparing meningitis-exposed subjects with non-exposed, matched controls.
• Data collection through interviews at inclusion and a two-month follow-up visit.
• Statistical analysis using Fisher exact test to compare sequelae frequencies.

Main Results:

• High frequencies of persistent symptoms: headaches (31.3%), asthenia (36.9%), and vertigo (22.4%).
• Significant motor impairment observed in 12.3% of exposed versus 1.6% of non-exposed subjects.
• Hearing loss affected 31.3% of exposed subjects, with 10.4% experiencing severe deafness.

Conclusions:

• Bacterial meningitis results in high rates of severe hearing loss and motor impairment.
• The high cost of interventions like cochlear implants and hearing aids is a barrier in developing countries.
• Public health authorities in Africa must prioritize developing rehabilitation centers for meningitis survivors.
