Overview
Salmonella meningitis is a rare but serious form of bacterial meningitis caused by Salmonella species, often complicating systemic Salmonella infections. It typically arises in immunocompromised individuals or those with underlying conditions that predispose to invasive Salmonella disease 1.Diagnosis
Clinical Presentation: Fever, headache, neck stiffness, altered mental status 1.
Laboratory Tests: Cerebrospinal fluid (CSF) analysis showing pleocytosis, elevated protein, and low glucose levels 1.
Culture and Sensitivity: CSF and blood cultures essential for confirming Salmonella species identification 1.
Imaging: MRI or CT scans may reveal meningeal enhancement or complications like abscesses 1.Management
Antibiotics: Initial empirical therapy with third-generation cephalosporins or carbapenems; adjust based on culture sensitivity 1.
Targeted Therapy: Once Salmonella species identified, switch to appropriate antibiotics such as ceftriaxone, amikacin, or fluoroquinolones 1.
Supportive Care: Hydration, seizure management, and monitoring for complications like hydrocephalus or subdural empyema 1.Special Populations
Immunocompromised Patients: Higher risk and may require prolonged or intensified antibiotic therapy 1.Key Recommendations
Thoroughly investigate patients with low back pain and recurrent Salmonella septicaemia for potential complications including meningitis, aortic aneurysm, osteomyelitis, and abscesses (Evidence: Expert opinion) 1.
Empiric broad-spectrum antibiotic therapy should be initiated early in suspected cases, followed by targeted therapy based on culture results (Evidence: Expert opinion) 1.
Consider imaging studies (MRI/CT) to identify complications such as abscesses or meningeal involvement in patients with Salmonella meningitis (Evidence: Expert opinion) 1.References
