Overview
Pneumococcal meningitis is an infection of the meninges caused by Streptococcus pneumoniae, often leading to severe neurological complications. Despite decreased complication rates due to antibiotic use, rare complications such as acute glomerulonephritis can still occur 1.Diagnosis
Clinical presentation includes fever, headache, neck stiffness, altered mental status 1.
Lumbar puncture essential for cerebrospinal fluid (CSF) analysis showing pleocytosis, elevated protein, and decreased glucose 1.
Gram stain and culture of CSF to identify S. pneumoniae 1.
Blood cultures may also be positive in up to 50% of cases 1.Management
First-line treatment: Intravenous (IV) penicillin G or ceftriaxone 1.
Adjunctive dexamethasone: To reduce hearing impairment and neurological sequelae, administered concurrently with antibiotics 1.
Supportive care: Includes management of increased intracranial pressure, seizure control, and renal function monitoring 1.Special Populations
Comorbidities: Acute glomerulonephritis can complicate the course in patients with underlying renal issues, though specific pediatric, pregnancy, or elderly considerations are not detailed in the provided abstracts 1.Key Recommendations
Initiate empirical IV antibiotic therapy with penicillin G or ceftriaxone upon suspicion of pneumococcal meningitis (Evidence: Strong 1).
Consider adjunctive dexamethasone to mitigate neurological complications (Evidence: Moderate 1).
Closely monitor renal function, especially in cases where acute glomerulonephritis may develop post-infection (Evidence: Weak 1).References
