Note (2): A 9– to 12–month course of treatment is recommended for tuberculous meningitis.^[6]^[7]

Note (3): Adjuvant Dexamethasone 0.3–0.4 mg/kg/day (max: 24 mg) is recommended unless drug resistance is suspected.^[8]^[9]

Note (4): Liaise with microbiology laboratory about genotype testing for drug resistance if there is high risk for MDR-TB.^[10]

Tuberculous meningitis caused by Mycobacterium tuberculosis resistant to isoniazid or rifampin

Isoniazid monoresistance^[11]

Substitute fluoroquinolone for isoniazid in intensive phase regimen.
Continue treatment with rifampin, pyrazinamide, and fluoroquinolone for 12 months.

Rifampin monoresistance^[12]

Substitute Fluoroquinolones for Rifampin in intensive phase regimen.
Continue treatment with isoniazid, pyrazinamide, and fluoroquinolone for 18 months.

MDR-TB (resistant to Isoniazid and Rifampin)^[13]

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.

XDR-TB (resistant to Isoniazid, Rifampin, Fluoroquinolones, and either Capreomycin, Kanamycin, or Amikacin)^[14]

Consider Ethionamide or Cycloserine to build the treatment regimen.
Consult infectious disease specialist.

Septic thrombosis of cavernous or dural venous sinus ⇧ Return to Top ⇧

Cavernous sinus thrombosis is considered a medical emergency.
Duration of therapy is usually a total of 3-4 weeks. More prolonged administration of antimicrobial therapy (total of 6-8 weeks) may be indicated among patients who are suspected to have developed complications (e.g. suppurative intracranial disease).
ENT surgery must be consulted to evaluate the need of surgical drainage (e.g. sphenoidotomy if sphenoid sinus infection is the primary cause).
Septic thrombosis of cavernous or dural venous sinus

1. Empiric antimicrobial therapy^[1]^[2]^[3]^[4]

Preferred regimen: (Vancomycin 30–45 mg/kg IV q8–12h for 3-4 weeks OR Nafcillin 2 g IV q4h for 3-4 weeks OR Oxacillin 2 g IV q4h for 3-4 weeks) AND (Ceftriaxone 2 g IV q12h for 3-4 weeks OR Cefotaxime 8–12 g/day IV q4–6h for 3-4 weeks) AND Metronidazole 7.5 mg/kg IV q6h 3-4 weeks

Note (1): If risk of MRSA is high, Vancomycin should be administered instead of either nafcillin or oxacillin

Note (2): The optimal duration of therapy remains unclear

2. Specific anatomic considerations

2.1 Cavernous sinus

Preferred regimen: Vancomycin 30–45 mg/kg IV q8–12h for 3-4 weeks AND (Ceftriaxone 2 g IV q12h for 3-4 weeks OR Cefotaxime 8–12 g/day IV q4–6h for 3-4 weeks) AND Metronidazole 7.5 mg/kg IV q6h for 3-4 weeks

2.3 Superior sagittal sinus

Preferred regimen: Ceftriaxone 2 g IV q12h for 3-4 weeks AND Vancomycin 15–20 mg/kg for 3-4 weeks AND Dexamethasone 10 mg IV q6h continued until symptomatic improvement and tailed gradually over several weeks
Alternative regimen: Meropenem 1–2 g IV q8h for 3-4 weeks AND Vancomycin 15–20 mg/kg for 3-4 weeks AND Dexamethasone 10 mg IV q6h continued until symptomatic improvement and tailed gradually over several weeks

3. Pathogen-directed antimicrobial therapy

Staphylococcus aureus, methicillin-resistant (MRSA)^[5]

Preferred regimen: Vancomycin 15–20 mg/kg/dose IV q8–12h for 4–6 weeks

Note (1): Surgical evaluation for incision and drainage of contiguous sites of infection or abscess is recommended whenever possible
Note (2): Consider the addition of Rifampin 600 mg qd or 300–450 mg bid to vancomycin

Subdural empyema ⇧ Return to Top ⇧

Subdural empyema^[6]^[7]

Empiric antimicrobial therapy

Metronidazole is recommended if anaerobes are suspected. Metronidazole is not necessary for antianaerobic activity if Meropenem is used.
For coverage of aerobic Gram-negative bacilli, empiric therapy with Cefepime, Ceftazidime, or Meropenem is appropriate.
Depending on the clinical response, parenteral antimicrobial therapy should be administered for 3 to 4 weeks after drainage. Parenteral or oral therapy is frequently continued for up to a total of 6 weeks of therapy.
A longer course of treatment (minimum of 6–8 weeks) may be required if the patient has accompanying osteomyelitis.
Consider adjunctive medications including prophylactic anticonvulsants, corticosteroids, and mannitol if clinically indicated.

Intracranial subdural empyema with unclear source of infection

Preferred regimen: (Nafcillin 2 g IV q4h for 3-4 weeks OR Oxacillin 2 g IV q4h for 3-4 weeks) AND (Ceftriaxone 2 g IV q12h for 3-4 weeks OR Cefotaxime 8–12 g/day IV q4–6h for 3-4 weeks) AND Metronidazole 7.5 mg/kg IV q6h for 3-4 weeks
Note: Vancomycin 30–45 mg/kg/day IV q8–12h should be used in place of nafcillin or oxacillin if MRSA is suspected or if penicillin allergy is present.
