[FDP levels in the cerebrospinal fluid are elevated in patients with meningitis].
Since the level of fibrinogen degradation products (FDP) are elevated with severity of inflammation, we assumed that FDP in the cerebrospinal fluid (CSF) could be a marker of meningitis. We, therefore, measured FDP in the CSF of 6 patients with bacterial meningitis and 6 aseptic meningitis. The range of FDP levels in the CSF in patients without meningitis was 0.21 +/- 0.01 microgram/ml. While, the level of FDP in patients with aseptic meningitis (0.43 +/- 0.10 microgram/ml) and in bacterial meningitis (1.78 +/- 0.42 micrograms/ml) was significantly elevated (p less than 0.05). The value was significantly (p less than 0.01) higher in the group of septic meningitis than in aseptic meningitis. In one patient with septic meningitis, we could measure FDP in the CSF several times during the course of the disease, in which the level of FDP got into the high range earlier than the changes in levels of protein, glucose and cell counts in the CSF. FDP in the CSF well correlated to the clinical course of the meningitis. Eventually, we found that FDP in the CSF was definitely elevated in patients with bacterial meningitis, whereas it was slightly elevated in patients with aseptic meningitis. The measurement of FDP in the CSF, therefore, is concluded to be useful for the differential diagnosis of meningitis, and to assess the clinical course of meningitis.
