==Overview==
Acute bacterial meningitis is a medical emergency. Empiric antimicrobial therapy must be administered after obtaining blood and/or [[cerebrospinal fluid|cerebrospinal fluid (CSF)]] cultures in cases of suspected meningitis. Once a bacterial etiology has been identified on a [[CSF]] [[Gram stain]], treatment regimen should be individualized accordingly.  Neither neuroimaging (such as [[CT scan]] and [[MRI]]) nor [[lumbar puncture]] should delay the administration of antimicrobial therapy. For neonates (age < 1 month), empirical antimicrobial therapy generally includes [[Ampicillin]] 12 g/day IV q4h {{and}} ([[Cefotaxime]] 8–12 g/day q4–6h {{or}} [[Amikacin]] 15 mg/kg/day IV q8h {{or}} [[Gentamicin]] 5 mg/kg/day IV q8h {{or}} [[Tobramycin]] 5 mg/kg/day IV q8h). For children older than 1 month and adults < 50 years, the preferred regimen is usually [[Vancomycin]] 30–45 mg/kg/day IV q8–12h {{and}} ([[Ceftriaxone]] 4 g IV q12–24h {{or}} [[Cefotaxime]] 8–12 g/day q4–6h). For adults ≥ 50 years of age, [[Ampicillin]] 12g/day IV q4h is added to the usual adult regimen. The duration of therapy is variable depending on the causative pathogen, but generally the duration is between 1-3 weeks. Adjunctive [[Dexamethasone]] at a dose of 0.15 mg/kg q6h for 2—4 days may be effective when administered early (0-20 minutes prior to administration of antimicrobial therapy) among pediatric patients with ''H. influenzae'' meningitis and among adults with ''S. pneumoniae'' meningitis.


==Principles of Therapy for Bacterial Meningitis==
==Principles of Therapy for Bacterial Meningitis==


* Acute bacterial meningitis is a medical emergency; commence empiric treatment after obtaining blood and/or [[cerebrospinal fluid|cerebrospinal fluid (CSF)]] cultures once the possibility of bacterial meningitis becomes evident. Antibiotic regimen should be adjusted according to the culture results.
===Factors Determining Antimicrobial Activity===
 
* Neuroimaging (such as [[CT scan]] and [[MRI]]) or [[lumbar puncture]] must not delay antimicrobial therapy.
 
====Factors Determining Antimicrobial Activity====


* Factors determine the acitivity of antimicrobial agents include [[pharmacodynamics]], [[pharmacokinetics]], penetration into the CSF, and [[bactericidal]] activity within the CSF.<ref name="Andes-1999">{{Cite journal  | last1 = Andes | first1 = DR. | last2 = Craig | first2 = WA. | title = Pharmacokinetics and pharmacodynamics of antibiotics in meningitis. | journal = Infect Dis Clin North Am | volume = 13 | issue = 3 | pages = 595-618 | month = Sep | year = 1999 | doi =  | PMID = 10470557 }}</ref>

* [[Aminoglycoside]]s and [[fluoroquinolone]]s express a concentration-dependent manner of bactericidal activity; [[beta-lactam]]s typically follow a a time-dependent antimicrobial pattern (i.e., the activity is dependent on the time that CSF concentration exceeds [[MIC]] as a proportion of the dosing interval).
* [[Aminoglycoside]]s and [[fluoroquinolone]]s express a concentration-dependent manner of bactericidal activity; [[beta-lactam]]s typically follow a a time-dependent antimicrobial pattern (i.e., the activity is dependent on the time that CSF concentration exceeds [[MIC]] as a proportion of the dosing interval).
* Adequate [[parenteral]] dosage should be maintained throughout the course to ensure adequate bactericidal concentration since antimicrobial entry attenuates as [[meninges|meningeal]] inflammation subsides, especially when adjunctive [[dexamethasone]] is co-administered.


* Penetration into the CSF is less prominent for drugs with a high [[molecular weight]], high protein-binding ability, low lipid solubility, and drugs that are subject to [[active transport]] in the [[choroid plexus]] such as [[penicillin]]s and [[cephalosporin]]s. Toxicity due to dose escalation may limit the usage the [[aminoglycoside]]s, [[glycopeptide]]s, and [[polymyxin]]s, thus [[intrathecal]] or [[intraventricular]] administration might be occasionally required (see table below).

====Adjunctive Dexamethasone Therapy====
* The duration of therapy in patients with bacterial meningitis has not been well-supported by evidence-based data.

* The IDSA Practice Guideline provides recommendations on the duration of antimicrobial agents based on microorganisms (see table below). However, the duration of antimicrobial therapy should be individualized in accordance with patient's clinical response.


* '''In adults with suspected or proven ''[[Streptococcus pneumoniae]]'' meningitis''', the IDSA also recommends '''''[[Dexamethasone]] at 0.15 mg/kg q6h for 2—4 days''''' with the first dose administered 10—20 minutes prior to, or at least concomitant with, the first antimicrobial dose. Dexamethasone should only be continued if the [[CSF]] [[Gram stain]] reveals [[Gram-positive]] [[diplococci]], or if blood or CSF cultures are positive for ''[[Streptococcus pneumoniae|S. pneumoniae]]''.

Overview

Acute bacterial meningitis is a medical emergency. Empiric antimicrobial therapy must be administered after obtaining blood and/or cerebrospinal fluid (CSF) cultures in cases of suspected meningitis. Once a bacterial etiology has been identified on a CSF Gram stain, treatment regimen should be individualized accordingly. Neither neuroimaging (such as CT scan and MRI) nor lumbar puncture should delay the administration of antimicrobial therapy. For neonates (age < 1 month), empirical antimicrobial therapy generally includes Ampicillin 12 g/day IV q4h AND (Cefotaxime 8–12 g/day q4–6h OR Amikacin 15 mg/kg/day IV q8h OR Gentamicin 5 mg/kg/day IV q8h OR Tobramycin 5 mg/kg/day IV q8h). For children older than 1 month and adults < 50 years, the preferred regimen is usually Vancomycin 30–45 mg/kg/day IV q8–12h AND (Ceftriaxone 4 g IV q12–24h OR Cefotaxime 8–12 g/day q4–6h). For adults ≥ 50 years of age, Ampicillin 12g/day IV q4h is added to the usual adult regimen. The duration of therapy is variable depending on the causative pathogen, but generally the duration is between 1-3 weeks. Adjunctive Dexamethasone at a dose of 0.15 mg/kg q6h for 2—4 days may be effective when administered early (0-20 minutes prior to administration of antimicrobial therapy) among pediatric patients with H. influenzae meningitis and among adults with S. pneumoniae meningitis.

Principles of Therapy for Bacterial Meningitis

Factors Determining Antimicrobial Activity

  • Aminoglycosides and fluoroquinolones express a concentration-dependent manner of bactericidal activity; beta-lactams typically follow a a time-dependent antimicrobial pattern (i.e., the activity is dependent on the time that CSF concentration exceeds MIC as a proportion of the dosing interval).
Recommended Doses of Antimicrobial Agents via the Intraventricular Route.[3][4][5]
Antimicrobial Agent Daily Intraventricular Dose
 ▸ Vancomycin 5—20 mg
 ▸ Gentamicin 4—8 mg
 ▸ Tobramycin 5—20 mg
 ▸ Amikacin 5—50 mg
 ▸ Polymyxin B 5 mg
 ▸ Colistin 10 mg
 ▸ Quinupristin/Dalfopristin 2—5 mg
 ▸ Teicoplanin 5—40 mg
 ▸ Amphotericin B 0.1—0.5 mg/day

Duration of Antimicrobial Therapy

  • The duration of therapy in patients with bacterial meningitis has not been well-supported by evidence-based data.
  • The IDSA Practice Guideline provides recommendations on the duration of antimicrobial agents based on microorganisms (see table below). However, the duration of antimicrobial therapy should be individualized in accordance with patient's clinical response.
  • Maximum parenteral dosage should be maintained throughout the recommended duration of therapy to ensure adequate bactericidal concentrations are attained since antimicrobial entry attenuates as meningeal inflammation subsides, especially when dexamethasone is co-administered.
Recommended Duration of Antimicrobial Therapy Based on Isolated Pathogen.[6]
Microorganism Duration of Therapy
 ▸ Neisseria meningitidis 7 days
 ▸ Haemophilus influenzae 7 days
 ▸ Streptococcus pneumoniae 10—14 days
 ▸ Streptococcus agalactiae 14—21 days
 ▸ Aerobic Gram-negative bacilli 21 days
 ▸ Listeria monocytogenes ≥21 days

Adjunctive Dexamethasone Therapy

  • Evidences for beneficial effects of dexamethasone are variable.
  • Adjunctive use of dexamethasone for bacterial meningitis in selected groups may be associated with an improved survival or prognosis.[7][8][9][10][11][12] However, other studies fail to demonstrate a substantial reduction of death or neurological disability.[3][13][14][15] The occurrence of delayed cerebral thrombosis with dexamethasone therapy has been reported.[16]
  • In infants and children with Haemophilus influenzae type b meningitis, the IDSA Practice Guideline supports the use of adjunctive Dexamethasone at 0.15 mg/kg q6h for 2—4 days with the first dose administered 10—20 minutes prior to, or at least concomitant with, the first antimicrobial dose.[6]
  • In adults with suspected or proven Streptococcus pneumoniae meningitis, the IDSA also recommends Dexamethasone at 0.15 mg/kg q6h for 2—4 days with the first dose administered 10—20 minutes prior to, or at least concomitant with, the first antimicrobial dose. Dexamethasone should only be continued either if the CSF Gram stain demonstrates Gram-positive diplococci or if blood or CSF cultures are positive for S. pneumoniae. In this scenario, certain authorities advocate the addition of rifampin to the empirical combination of vancomycin plus a third-generation cephalosporin pending culture results and in vitro susceptibility testing.[6][17]
  • Dexamethasone should not be administered to patients who have already received animicrobial therapy because it is unlikely to improve clinical outcome.[6]
