Abstract

Insights

Meningococcal infections in children are primarily caused by serogroups B and W-135, predominantly affecting infants under one year old. Continuous surveillance and prevention strategies are crucial for managing pediatric meningococcus cases.

Area of Science:

  • Pediatric Infectious Diseases
  • Epidemiology
  • Bacteriology

Background:

  • Neisseria meningitidis infections are typically severe in children but were historically sporadic in Taiwan.
  • A notable increase in meningococcal infections was observed in Taiwan during 2001-2002.
  • This study addresses the epidemiology and clinical features of meningococcal disease in pediatric patients.

Purpose of the Study:

  • To investigate the epidemiology of meningococcal infections in a pediatric population in Taiwan.
  • To describe the clinical manifestations and outcomes of meningococcal disease in children.
  • To identify predominant serogroups and risk factors in pediatric cases.

Main Methods:

  • Retrospective review of medical charts of pediatric patients with meningococcal disease from July 1998 to December 2005.
  • Analysis of patient demographics, serogroups, clinical diagnoses, treatments, and complications.
  • Evaluation of patient outcomes, including survival and long-term sequelae.

Main Results:

  • Sixteen pediatric cases of meningococcal disease were identified, with ages ranging from 1 month to 15 years.
  • Serogroups B (43.75%) and W-135 (31.25%) were the most prevalent.
  • Common acute complications included purpura fulminans (37.5%) and disseminated intravascular coagulopathy (31.25%); the mortality rate was 12.5%.

Conclusions:

  • Serogroups B and W-135 are the primary causes of pediatric meningococcal infections in the studied population.
  • Infants under one year of age represent the majority of affected children.
  • Ongoing surveillance and preventive measures are essential for controlling meningococcal disease in children.

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...
Bacterial Meningitis I: Introduction01:22

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...
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...
Viral Meningitis01:18

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...
Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
