    Abstract:
    OBJECTIVE: To study the application value of procalcitonin (PCT) in patients with central nervous system (CNS) infection. PATIENTS AND METHODS: A total of 66 patients, including 24 patients with suppurative meningitis, 20 patients with viral meningitis and 22 patients with tuberculous meningitis, were enrolled. 20 patients admitted to the hospital due to epilepsy or headache without infection in the same period were enrolled as the control group. PCT, high-sensitivity C-reactive protein (Hs-CRP), high-sensitivity C-reactive protein (Hs-CRP), protein quantification, chloride and glucose in serum and cerebrospinal fluid, were collected. RESULTS: The serum PCT level in suppurative meningitis group was significantly higher than that in other three groups. The dynamic monitoring of suppurative meningitis group on admission, at 72 h and 1 week after treatment showed that the serum PCT level was significantly decreased. PCT levels in cerebrospinal fluid in suppurative meningitis group, viral meningitis group and tuberculous meningitis group were decreased successively, and the differences were statistically significant. The detection of PCT in cerebrospinal fluid was more valuable than serum PCT detection in distinguishing tuberculous meningitis from viral meningitis. Continuous monitoring of changes in PCT in cerebrospinal fluid showed that there was no statistically significant difference before and after treatment. PCT level in cerebrospinal fluid was positively correlated with the serum PCT, cerebrospinal fluid white blood cell (WBC), and protein content in cerebrospinal fluid. CONCLUSIONS: The dynamic changes of serum PCT in patients with suppurative meningitis can be used to evaluate the disease, guide the clinical medication, and monitor the prognosis.
