Insights

Pediatric purulent meningitis cases were analyzed in Japan. Drug-resistant bacteria like Haemophilus influenzae and Streptococcus pneumoniae are increasing, necessitating treatment reconsideration.

Area of Science:

  • Epidemiology
  • Infectious Diseases
  • Pediatrics

Context:

  • Purulent meningitis poses a significant threat to pediatric populations.
  • Understanding causative pathogens and their resistance patterns is crucial for effective treatment.

Purpose:

  • To survey the epidemiology of pediatric purulent meningitis in Japan.
  • To identify common pathogens and assess their antimicrobial resistance.
  • To evaluate the implications for current treatment strategies.

Summary:

  • A 3-year survey (1997-2000) identified 428 cases of pediatric purulent meningitis in Japan.
  • Infections were most common in infants under one year, particularly neonates.
  • Key pathogens included Haemophilus influenzae, Streptococcus pneumoniae, group B Streptococcus, and Escherichia coli.
  • Significant drug resistance was observed in H. influenzae (25.3%) and S. pneumoniae (38.7%) isolates.
  • Resistance rates were higher when analyzing resistant genes, suggesting underestimation in standard susceptibility tests.

Impact:

  • Findings indicate a rising prevalence of drug-resistant bacteria, potentially reducing the efficacy of standard treatments like ampicillin and cefotaxime.
  • The study highlights the urgent need to reconsider and adapt treatment protocols for pediatric purulent meningitis.
  • This research contributes to public health strategies for managing pediatric infectious diseases and antimicrobial resistance.

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

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...
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...
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...
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...
Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
