Treatment of Streptococcal Pneumonia Meningitis

Immediate Management Algorithm

The Infectious Diseases Society of America recommends starting antibiotics within 1 hour of hospital presentation, as delays in treatment are strongly associated with death and poor outcomes 1, 2, 3
The European Society of Clinical Microbiology and Infectious Diseases suggests drawing blood cultures immediately, but never delaying antibiotics while awaiting lumbar puncture or imaging results 1, 2
The American College of Physicians advises starting empiric treatment immediately on clinical suspicion if lumbar puncture is delayed due to cranial imaging 1, 2, 3

The Infectious Diseases Society of America recommends ceftriaxone 2g IV every 12 hours (or cefotaxime 2g IV every 4-6 hours) PLUS vancomycin 10-20 mg/kg IV every 8-12 hours for adults 18-50 years 1, 2, 3
The European Society of Clinical Microbiology and Infectious Diseases suggests adding amoxicillin 2g IV every 4 hours to cover Listeria monocytogenes for adults >50 years or immunocompromised 1, 2, 4
The American Academy of Pediatrics recommends ceftriaxone 50mg/kg IV every 12 hours (maximum 2g every 12 hours) OR cefotaxime 75mg/kg IV every 6-8 hours PLUS vancomycin 10-15mg/kg IV every 6 hours for pediatric patients 1 month to 18 years 1, 2, 3

The Infectious Diseases Society of America recommends switching to ceftriaxone 2g IV every 12 hours alone (or cefotaxime 2g IV every 6 hours) for penicillin-sensitive pneumococcus (MIC ≤0.06 mg/L), with a duration of 10 days if clinically stable by day 10, and 14 days if slower response 4, 5, 6
The European Society of Clinical Microbiology and Infectious Diseases suggests continuing ceftriaxone 2g IV every 12 hours alone for penicillin-resistant but cephalosporin-sensitive pneumococcus (penicillin MIC >0.06, ceftriaxone MIC ≤0.5 mg/L), with a duration of 10-14 days 4, 5

The Infectious Diseases Society of America does not provide specific recommendations for dexamethasone use in this context, however, other sources suggest administering dexamethasone 10mg IV every 6 hours for 4 days, ideally 15-20 minutes before or with the first antibiotic dose, although this information is not directly cited here

The Infectious Diseases Society of America recommends verifying adequate vancomycin CSF penetration (trough levels 15-20 μg/mL) if clinical response is not achieved by 72 hours 1, 4
The European Society of Clinical Microbiology and Infectious Diseases suggests adding rifampicin 600mg IV/PO every 12 hours if not already included for treatment failure 4
