Suspected acute meningitis/meningococcemia with rash
This presentation (headache, fever, vomiting, rash, and tachycardia) requires immediate treatment for invasive meningococcal disease and acute bacterial meningitis without waiting for diagnostic confirmation. [1], [2]
Immediate actions and infection control
- Manage in an emergency/acute-care setting with rapid stabilization and continuous monitoring for shock and respiratory compromise. [2]
- Use droplet precautions for suspected meningococcal disease until effective therapy has been given. [1]
- Obtain blood cultures and perform diagnostic testing without delaying empiric antimicrobial administration. [2]
Diagnostic evaluation
- Evaluate for meningitis and septicemia syndromes associated with invasive meningococcal disease. [1]
- Perform lumbar puncture when not contraindicated to support diagnosis of acute bacterial meningitis. [2]
- Perform CSF and blood testing including bacterial culture and nucleic-acid amplification testing when available. [1], [2]
Empiric antimicrobial therapy
- Administer empiric intravenous ceftriaxone or cefotaxime as the immediate parenteral antimicrobial regimen for suspected acute bacterial meningitis. [2]
- Administer empiric extended-spectrum cephalosporin therapy promptly for suspected meningococcal disease because of risk of severe morbidity and death. [1]
Adjunctive corticosteroid therapy
- Initiate intravenous corticosteroids with the first dose of antibiotics when suspected acute bacterial meningitis is being evaluated and lumbar puncture can be performed in a non-epidemic setting. [2]
- Consider discontinuation of corticosteroids when CSF findings are not consistent with bacterial meningitis. [2]
Supportive and complication-directed care
- Provide inpatient supportive care tailored to severity, including management for shock and increased intracranial pressure when clinically indicated. [2]
- Use isotonic maintenance intravenous fluids when oral/enteric hydration is not feasible and reassess for SIADH or hypovolemia. [2]
Public health management and close-contact prophylaxis
- Notify public health authorities promptly when meningococcal disease is suspected to support outbreak detection and control. [1]
- Provide antibiotic prophylaxis to close contacts of laboratory-confirmed or clinically suspected cases of meningococcal disease using single-dose parenteral ceftriaxone or oral ciprofloxacin, based on available resources and local protocols. [2]
Treatment reassessment and de-escalation
- Continue empiric therapy until pathogen identification and susceptibilities guide definitive antimicrobial selection. [1], [2]
- Use clinical status and diagnostic results to determine duration of therapy, with discontinuation of empiric antibiotics potentially considered after 7 days in non-epidemic settings when the patient has clinically recovered and no pathogen has been identified. [2]
Safety monitoring and disposition
- Reassess for meningitis sequelae prior to discharge and at follow-up. [2]
- Arrange referral for detected sequelae and provide rehabilitation when sequelae are present. [2]
