Abstract

Insights

Pre-admission antibiotics for suspected meningococcal disease lack reliable evidence for effectiveness. One trial showed ceftriaxone and chloramphenicol were equally safe and effective, but further research is needed.

Area of Science:

  • Infectious Diseases
  • Clinical Pharmacology
  • Evidence-Based Medicine

Background:

  • Meningococcal disease is a rapidly progressing illness with high mortality.
  • Pre-admission antibiotic therapy aims to reduce treatment delays.
  • Timely intervention is crucial for improving outcomes in suspected meningococcal infections.

Purpose of the Study:

  • To evaluate the effectiveness and safety of pre-admission antibiotics versus no pre-admission antibiotics or placebo.
  • To compare different pre-admission antibiotic regimens for suspected meningococcal disease.
  • To assess the impact on mortality and morbidity.

Main Methods:

  • Searched CENTRAL, MEDLINE, and EMBASE databases.
  • Included randomized controlled trials (RCTs) and quasi-RCTs.
  • Compared antibiotic treatment versus placebo/no intervention or different antibiotic regimens administered before hospital admission.

Main Results:

  • No RCTs compared pre-admission antibiotics to placebo or no intervention.
  • One RCT found intramuscular ceftriaxone and long-acting chloramphenicol equally effective and safe.
  • No significant differences in mortality, neurological sequelae, or clinical failures were observed between the two antibiotics.

Conclusions:

  • No reliable evidence supports or refutes pre-admission antibiotics for suspected meningococcal disease.
  • Ceftriaxone and chloramphenicol demonstrated comparable safety and efficacy in one study.
  • Further RCTs are needed to guide clinical practice, especially for severe cases.

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...
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...

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,...
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...

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
