Clinical guidelines for meningitis in low- and middle-income countries

Area of Science:

• Neurology
• Infectious Diseases
• Public Health

Background:

• Meningitis is a significant global health concern.
• Typical symptoms include fever and neurological deficits.
• Atypical presentations in older or immunocompromised patients necessitate a high index of suspicion.

Purpose of the Study:

• To highlight the importance of early recognition and prompt empirical therapy for meningitis.
• To emphasize the need for cerebrospinal fluid analysis and neuroimaging in suspected cases, particularly those with atypical presentations.

Main Methods:

• Review of clinical presentations of meningitis.
• Discussion of diagnostic approaches including cerebrospinal fluid analysis and neuroimaging.
• Emphasis on empirical treatment strategies.

Main Results:

• Bacterial meningitis is the most common cause globally.
• Tuberculous meningitis is a leading cause in endemic areas, often presenting acutely.
• Atypical presentations in specific populations can delay diagnosis.

Conclusions:

• Early recognition and prompt empirical therapy, including antimicrobials and dexamethasone, are critical for improving meningitis outcomes.
• A low threshold for diagnostic workup is essential, especially in at-risk populations.
• Understanding diverse clinical presentations is key to effective management.
