In a patient with Bacterial Meningitis, what is primarily expected in the laboratory analysis?

• A. High protein levels in the CSF
• B. Normal glucose levels in the CSF
• C. Low glucose levels in the CSF
• D. Elevated white blood cell counts in the CSF

Answer: (C)

In cases of bacterial meningitis, one of the hallmark findings in cerebrospinal fluid (CSF) analysis is low glucose levels. This occurs due to the consumption of glucose by bacteria and inflammatory cells, which leads to a significant decrease in glucose concentrations compared to normal levels. In this condition, the body’s immune response and the presence of bacteria in the CSF cause an increase in metabolic activity that depletes glucose. Typically, in viral meningitis, glucose levels remain normal, but bacterial infections uniquely cause this depletion. Alongside low glucose levels, elevated white blood cell counts, particularly with a predominance of neutrophils, and high protein levels in the CSF are also observed in bacterial meningitis. However, the consistent finding that distinguishes it in relation to glucose is the marked reduction, which is a critical aspect of diagnosing bacterial versus viral meningitis.
