Abstract

Insights

Meningococcal disease (MCD) is increasingly presenting as septicaemia alone, not just meningitis. This life-threatening presentation, characterized by a petechial rash, affects nearly one in five children with septicaemia alone.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Epidemiology

Background:

  • Meningococcal disease (MCD) encompasses meningitis, meningitis with septicaemia, and septicaemia alone.
  • Previous understanding often equated MCD primarily with meningitis.

Purpose of the Study:

  • To investigate the trend in the proportion of MCD cases presenting as septicaemia alone over a 17-year period.
  • To analyze mortality rates associated with different presentations of MCD.

Main Methods:

  • Retrospective analysis of 449 pediatric MCD admissions between 1977 and 1993.
  • Comparison of MCD presentation proportions and mortality rates across different time intervals within the study period.

Main Results:

  • The proportion of MCD cases presenting as septicaemia alone significantly increased from 7% (1977-1985) to 36% (1990-1993).
  • Mortality was highest in children with septicaemia alone (19%).
  • Overall MCD mortality did not change significantly despite the rise in septicaemia cases.

Conclusions:

  • Meningococcal disease (MCD) should be recognized as frequently presenting with septicaemia alone (33% of cases).
  • Septicaemia alone is a critical, life-threatening presentation of MCD, with nearly 20% mortality.
  • Public health information on MCD should emphasize septicaemia, particularly the presence of a petechial rash.

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 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 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,...

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...

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...
