Overview
Acute meningitis involves inflammation of the meninges, typically caused by bacterial, viral, or fungal pathogens, leading to symptoms such as fever, headache, and altered mental status. 1 does not directly address acute meningitis but highlights the importance of fungal infections in immunocompromised patients, which can present with meningeal signs.Diagnosis
Clinical presentation: Fever, headache, neck stiffness, altered mental status 1.
Lumbar puncture: Essential for cerebrospinal fluid (CSF) analysis, including cell count, protein, glucose levels, and culture 1.
CSF Gram stain and culture: For bacterial meningitis 1.
CSF PCR: Useful for viral and specific bacterial pathogens 1.
Fungal cultures and antigen testing: Important in immunocompromised patients 1.
Imaging: MRI or CT scans may be needed to rule out complications like abscesses 1.Management
Bacterial meningitis: Third-generation cephalosporins (e.g., ceftriaxone) or penicillin-based regimens 1.
Viral meningitis: Supportive care; acyclovir if herpes simplex virus is suspected 1.
Fungal meningitis: Amphotericin B for severe cases, with fluconazole as an alternative for less severe or prophylaxis 1.
Adjunctive dexamethasone: Recommended in bacterial meningitis to reduce hearing impairment and mortality 1.
Monitoring: Close observation for complications and response to treatment 1.
Immunocompromised patients: Tailored antifungal therapy based on susceptibility testing 1.Special Populations
Immunocompromised patients: Higher risk of fungal infections like Blastoschizomyces capitatus; aggressive antifungal therapy is crucial 1.
No specific recommendations for pregnancy, pediatrics, or elderly populations provided in the given abstracts 1.Key Recommendations
Perform lumbar puncture with CSF analysis for definitive diagnosis of acute meningitis (Evidence: Moderate 1).
Initiate broad-spectrum antibiotics empirically in suspected bacterial meningitis until culture results guide specific therapy (Evidence: Moderate 1).
Use amphotericin B for severe fungal meningitis in immunocompromised patients, guided by susceptibility testing (Evidence: Weak 1).References
