Insights

Beta-trace protein (beta-trace) levels in cerebrospinal fluid (CSF) are significantly decreased in bacterial meningitis patients. This finding suggests beta-trace may help understand bacterial meningitis pathophysiology.

Area of Science:

  • Neurology
  • Biochemistry
  • Infectious Diseases

Background:

  • The meninges are a primary site for beta-trace protein (beta-trace) biosynthesis.
  • Beta-trace protein's role in cerebrospinal fluid (CSF) during meningitis remains understudied.

Purpose of the Study:

  • To investigate beta-trace concentrations in the CSF of patients with bacterial meningitis and other neurological conditions.
  • To evaluate the potential of beta-trace as a biomarker in meningitis.

Main Methods:

  • Quantitative measurement of beta-trace in lumbar CSF using an immunonephelometric assay.
  • Comparison of beta-trace levels in normal controls, bacterial meningitis, viral meningoencephalitis, and spinal canal stenosis patient groups.

Main Results:

  • CSF beta-trace levels were significantly decreased in bacterial meningitis (8.7+/-3.9 mg/l) compared to controls (16.6+/-3.6 mg/l).
  • Elevated CSF beta-trace was observed in spinal canal stenosis (29.2+/-10.3 mg/l), while viral meningoencephalitis showed normal levels.
  • Decreased beta-trace persisted even after bacterial meningitis resolution and normalization of CSF parameters.

Conclusions:

  • Beta-trace protein levels are significantly reduced in the CSF during bacterial meningitis.
  • Beta-trace may serve as a valuable indicator for studying the pathophysiology of bacterial meningitis.
  • Further research is warranted to explore the clinical utility of beta-trace in neurological disorders.

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 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...
