Serum C-reactive protein as detector of pretreated childhood bacterial meningitis

Area of Science:

• Pediatrics
• Infectious Diseases
• Clinical Chemistry

Background:

• Bacterial meningitis (BM) is a serious infection requiring prompt diagnosis and treatment.
• Differentiating BM from viral meningitis is crucial for appropriate patient management.
• Serum C-reactive protein (CRP) is a common biomarker for inflammation.

Purpose of the Study:

• To evaluate the diagnostic utility of serum C-reactive protein (CRP) levels in children with suspected meningitis.
• To determine if CRP levels can differentiate between bacterial and viral meningitis.

Main Methods:

• Serum CRP levels were measured in 15 children with confirmed bacterial meningitis (BM) who had received antibiotics.
• Serum CRP levels were also measured in 12 patients diagnosed with viral meningitis or meningoencephalitis.
• CRP levels were compared between the two groups.

Main Results:

• All 15 children with BM exhibited CRP levels exceeding the normal limit of 19 mg/l (mean 195 mg/l, range 55-375 mg/l).
• In contrast, 12 patients with viral meningitis had normal CRP levels.
• A significant difference in CRP levels was observed between bacterial and viral meningitis groups.

Conclusions:

• Serum CRP is a highly sensitive marker for bacterial meningitis in children, even after antibiotic pretreatment.
• Rapid CRP determination is valuable in the emergency setting for suspected BM.
• CRP levels can effectively distinguish bacterial from viral meningitis in pediatric patients.
