Abstract

Insights

Bacterial meningitis frequently causes lasting neurological issues like hearing loss and motor impairment in Niger. This highlights the urgent need for accessible rehabilitation services in developing nations.

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.

Bacterial Meningitis II: Pathophysiology01:26

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
