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 CSFGram 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 ORAmikacin 15 mg/kg/day IV q8h ORGentamicin 5 mg/kg/day IV q8h ORTobramycin 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 ORCefotaxime 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.
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).
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]
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 CSFGram stain demonstrates Gram-positivediplococci 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]
Common causative pathogens: Aerobic Gram-negative bacilli (including P. aeruginosa), S. aureus, coagulase-negative staphylococci (especially S. epidermidis)
Common causative pathogens: Coagulase-negative staphylococci (especially S. epidermidis), S. aureus, aerobic Gram-negative bacilli (including P. aeruginosa), Propionibacterium acnes

Note (1): World Health Organization guidelines recommend that Ethambutol should be replaced by Streptomycin in tuberculous meningitis.[24] Streptomycin is contraindicated in pregnancy.
Note (2): A 9– to 12–month course of treatment is recommended for tuberculous meningitis.[25][26]
Note (3): Adjuvant Dexamethasone 0.3–0.4 mg/kg/day (max: 24 mg) is recommended unless drug resistance is suspected.[27][28]
Note (4): Liaise with microbiology laboratory about genotype testing for drug resistance if there is high risk for MDR-TB.[29]
3.7.4 Tuberculous meningitis caused by Mycobacterium tuberculosis resistant to isoniazid or rifampin
3.7.4.3 MDR-TB (resistant to Isoniazid and Rifampin)[32]
MDR tuberculosis therapy should be considered if there is a history of prior tuberculosis treatment, contact with a patient with MDR tuberculosis, or a poor clinical response to first-line TB therapy within 2 weeks despite a firm diagnosis and an adequate adherence to treatment.
Second-line agents such as Aminoglycosides penetrate the BBB only in the presence of inflamed meninges, and Fluoroquinolones, while able to penetrate into the CNS, have lower CSF levels than in the serum or brain parenchyma.
Consult infectious disease specialist.
