Insights

Intrathecal colistin for resistant Gram-negative meningitis can cause chemical meningitis. Discontinuing this treatment improved cerebrospinal fluid findings, suggesting dose reduction or cessation as management strategies.

Area of Science:

  • Neuroscience
  • Infectious Diseases
  • Pharmacology

Background:

  • Nosocomial meningitis presents a significant challenge due to multi-drug resistant Gram-negative bacteria.
  • Colistin is a critical treatment for infections caused by these resistant strains.
  • Intrathecal colistin administration is sometimes necessary but carries risks.

Observation:

  • A case of chemical meningitis occurred during treatment for multi-drug resistant *Acinetobacter baumannii* meningitis.
  • The patient received intravenous sulbactam plus colistin and intrathecal colistin.
  • Cerebrospinal fluid (CSF) findings improved upon cessation of intrathecal colistin.

Findings:

  • Intrathecal colistin therapy can precipitate reversible chemical meningitis.
  • This complication is characterized by changes in cerebrospinal fluid parameters.
  • Discontinuation or dose reduction of intrathecal colistin is a viable management approach.

Implications:

  • Clinicians should be vigilant for chemical meningitis during intrathecal colistin therapy.
  • Early recognition and management, such as drug cessation, can reverse this complication.
  • This highlights the need for careful dosing and monitoring in neuroinfectious disease treatment.

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...

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...
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...

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...

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
