- Listeria monocytogenes (neonates and patients > 50, and immunocompromised patients)
What can be given to patients with meningitis to prevent neurologic symptoms
- Dexamethasone 15-20 minutes prior to abx admin
- 0.15 mg/kg rounded to 10 mg IV q6h
What is meningitis treatment duration dependent on and what is it?
- 7 days for N. Meningit and H. FLu
- 10-14 for S. pneumo
- 21 days for listeria
Empiric treatment recommendations for meningitis
<1mo
1-23 months
age 2-50 years
>50 or immunocompromised
< 1 mo
- Ampicillin for listeria coverage
- cefotaxime (not ceftriaxone due to risk of biliary sludging in neonates)
- or Gentamicin
1-23 months
- Ceftriaxone or cefotaxime
- Vanc
2-50 years
- Adult dose
- Ceftriaxone 2 g IV q12 or Cefotaxime 2 g q4-6h
- vanc 30-45 mg/kg/day in divided doses
>50
- Ceftriaxone or cefotaxime
- Vanc
- Ampicllin for listeria coverage
What Abx is added for neonates or people > 50 or immunocompromised to cover listeria
Ampicillin
If pt has a serious PCN allergy what is the treatment regimen for meningitis?
- Quinolones (moxi or levo) + vanc +- Bactrim for listeria
