Abstract

Insights

Infectious disease specialists show varied practices in managing meningococcal disease, with inconsistent antimicrobial susceptibility testing for Neisseria meningitidis. These differences are important for developing future treatment guidelines.

Area of Science:

  • Infectious Diseases
  • Microbiology
  • Clinical Practice

Background:

  • Management of meningococcal disease presents uncertainties despite established bacterial meningitis treatments.
  • Practices and antimicrobial susceptibility testing availability for Neisseria meningitidis were assessed.

Purpose of the Study:

  • To evaluate current practice patterns and opinions among infectious disease specialists regarding meningococcal disease.
  • To determine the availability of antimicrobial susceptibility testing for Neisseria meningitidis.

Main Methods:

  • An online survey was distributed to 1342 pediatric and adult infectious disease specialists.
  • The survey covered diagnosis, treatment, prevention, and antimicrobial susceptibility testing for Neisseria meningitidis.

Main Results:

  • A 48% response rate (650 specialists) was achieved.
  • Significant variations were observed in treatment choices (e.g., penicillin use), species confirmation for therapy adjustment, susceptibility testing availability (over one-third reported it's not routine), complement deficiency screening, and chemoprophylaxis practices.
  • Pediatric specialists were more likely to use penicillin than adult specialists.

Conclusions:

  • Infectious disease specialists exhibit considerable variation in managing meningococcal disease.
  • Routine antimicrobial susceptibility testing for Neisseria meningitidis is lacking in many clinical settings.
  • Acknowledging these practice variations is crucial for refining treatment and prevention recommendations.

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...
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...

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
