Insights

Sensorineural hearing loss is a significant risk following bacterial meningitis in children. Vaccination against Streptococcus pneumoniae and Haemophilus influenzae type b can help prevent this hearing impairment in developing nations.

Area of Science:

  • Pediatric infectious diseases
  • Audiology
  • Epidemiology

Background:

  • Meningitis is a serious infection that can lead to long-term complications in children.
  • Sensorineural hearing loss is a common sequela of bacterial meningitis.
  • Developing countries face a high burden of vaccine-preventable diseases.

Purpose of the Study:

  • To evaluate the incidence of sensorineural hearing loss in children after meningitis in southern India.
  • To identify the common etiological agents of meningitis in this population.
  • To inform vaccination strategies for preventing hearing loss.

Main Methods:

  • Prospective pilot study conducted in a tertiary pediatric hospital.
  • Cerebrospinal fluid cultures analyzed for bacterial identification.
  • Audiometric evaluations performed on eligible patients.

Main Results:

  • Sixty-five pediatric patients were included in the study.
  • Streptococcus pneumoniae and Haemophilus influenzae were the most frequent bacterial pathogens identified.
  • Twenty-eight percent of evaluated patients exhibited sensorineural hearing loss post-meningitis.

Conclusions:

  • The etiological profile of bacterial meningitis in southern India resembles that of developed countries, with the addition of tuberculous meningitis.
  • The prevalence of postmeningitic sensorineural hearing loss is comparable to findings in developed nations.
  • Implementing vaccination programs against S. pneumoniae and H. influenzae type b is crucial for reducing hearing loss in developing countries.

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...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Bacterial Meningitis01:24

Bacterial Meningitis

Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...

Vaccines

Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the type of...
