Abstract

Insights

Hypoalbuminemia, increased pulse rate, and central venous line infections are risk factors for poor outcomes in Chryseobacterium meningosepticum infections. Antibiotic choice did not significantly impact patient survival in this study.

Area of Science:

  • Infectious Diseases
  • Clinical Microbiology
  • Critical Care Medicine

Background:

  • Limited antibiotic options exist for Chryseobacterium meningosepticum infections.
  • The role of C. meningosepticum in neonates and immunocompromised patients is recognized, but clinical data are scarce.
  • This study addresses the limited clinical data on C. meningosepticum infections.

Purpose of the Study:

  • To investigate risk factors for mortality in patients with C. meningosepticum infections.
  • To determine the antibiotic susceptibility profiles of clinical C. meningosepticum isolates.
  • To identify prognostic indicators for C. meningosepticum infections.

Main Methods:

  • Retrospective analysis of patient data, including demographics, clinical parameters, and treatment.
  • Statistical analysis using Fisher's exact test to identify prognostic parameters.
  • Antimicrobial susceptibility testing of 19 isolates against seven antibiotics, reporting MIC values.

Main Results:

  • Hypoalbuminemia, elevated pulse rate, and central venous line presence were associated with poor outcomes (p<0.05).
  • Appropriate antibiotic use did not show a significant association with clinical outcomes (p=0.21).
  • Levofloxacin demonstrated lower MIC values (MIC50/90: 0.12/2 µg/mL) compared to ciprofloxacin (MIC50/90: 0.5/4 µg/mL).

Conclusions:

  • Hypoalbuminemia, increased pulse rate, and central venous line infections are significant predictors of poor outcomes.
  • These findings highlight key clinical factors associated with mortality in C. meningosepticum infections.
  • Antibiotic susceptibility data provide insights into treatment options, with levofloxacin showing promising activity.

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: 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...

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...
Mechanism of Antibiotic Resistance in MRSA01:25

Mechanism of Antibiotic Resistance in MRSA

Antibiotic resistance in bacteria arises when microorganisms evolve the ability to withstand drugs designed to kill them or inhibit their growth, rendering once-effective treatments useless. This phenomenon, driven by genetic change and selection under antibiotic exposure, poses a profound threat to modern medicine. Mechanisms include drug-inactivating enzymes (e.g., β-lactamases), efflux pumps that eject antibiotics, mutations altering antibiotic targets, decreased drug uptake, and acquisition...
Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...

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,...
