The aetiology of central nervous system infections was surveyed in a study at Aurora Hospital, Helsinki, in 1980. Of the 146 patients with central nervous system infections, 113 had
aseptic meningitis
, 23 bacterial and one tuberculous meningitis, and nine meningoencephalitis or encephalitis. The probable aetiology of
aseptic meningitis
was established in 67% of the 106 patients properly tested, the commonest agents being mumps (27%), Coxsackie (24%) and ECHO (9%) viruses. Haemophilus influenza type b was the most frequent cause of
bacterial meningitis
(39%), occurring solely among infants and young children. There were no cases due to Neisseria meningitidis group A, which used earlier to be epidemic in Finland. The incidences of aseptic, bacterial and tuberculous meningitis in Helsinki in 1980 (based on a total of 174 patients treated in the three hospitals admitting patients with central nervous system infections) were 26.7, 5.2 and 0.2 cases per 100,100 annually, and those of encephalitides and myelitis 3.5 and 0.6 cases per 100,000 annually.

An outbreak of
aseptic meningitis
involving 36 children is described. Enterovirus type 71, a recently recognized cause of central nervous system and systemic illness in children, was found to be the responsible agent. On initial lumbar puncture, cerebrospinal fluid (CSF) polymorphonuclear (PMN) cell predominance was seen in 64%, and greater than 200 CSF white blood cells (WBC)/mm3 was seen in 25% of these patients. Fifty-four per cent of the patients subjected to repeat lumbar puncture and a significant rise in the number of CSF WBC/mm3, the majority with the maintenance of a PMN cell predominance. The CSF white blood cell findings of individual patients did not allow for differentiation from patients concurrently seen with
bacterial meningitis
. Both initial and serial measurements of CSF lactic acid dehydrogenase reliably distinguished these two groups of patients.

The hematologic values in patients with Haemophilus influenzae meningitis were contrasted with those of patients with other types of
bacterial meningitis
and
aseptic meningitis
in an attempt to determine whether anemia is either specific for or more common in patients with H influenzae meningitis. Patients with H influenzae meningitis had significantly lower admission hemoglobin values because they were significantly younger than the other two groups. The H influenzae meningitis patients with the lowest hemoglobin values on admission had been sicker for longer periods prior to diagnosis and had higher initial white cell counts. Patients with H influenzae meningitis, aged 3 to 24 months, developed lower hemoglobin values during hospitalization than did patients with other forms of meningitis. Anemia occurs with all forms of
bacterial meningitis
but is uncommon in
aseptic meningitis
. The anemia observed in patients with H influenzae meningitis, particularly those less than 2 years of age, is generally more severe than that observed in other forms of
bacterial meningitis
.

The concentrations of cefoxitin in serum and cerebrospinal fluid (CSF) were measured simultaneously in three groups of patients, 12 with
aseptic meningitis
(group 1) and 17 and 14 with
bacterial meningitis
(groups 2 and 3). The patients in group 1 received a single intravenous dose of 2 g of cefoxitin without other antimicrobial therapy. In addition to conventional doses of ampicillin or benzyl penicillin, patients in groups 2 and 3 received repeated infusions of 2 g of cefoxitin every 4 h for the first 3 or 4 days of the study and again on day 10. Additionally, group 3 received probenecid in a loading dose of 1 g followed by 0.5 g every 6 or 8 h. Concentrations of cefoxitin in CSF and serum were determined 1 or 2 h after infusion in group 2 and 2 h after infusion in group 3. The concentrations of cefoxitin in CSF did not reach detectable levels (1.56 microgram/ml) in 11 of the 12 patients in group 1. A level of 2.8 microgram of cefoxitin per ml of CSF was found, with an accompanying level of 30 microgram/ml of serum, in patient 12. In the group 2 patients with
bacterial meningitis
, the mean CSF concentrations were 3.3, 4.7, and 2.9 microgram/ ml on days 1, 3, and 10 of treatment, with simultaneous serum levels of 8, 9, and 8 microgram/ml. At similar times periods, the mean levels of cefoxitin in group 3 patients (with concomitant probenecid) were 8.6, 12.3, and 4.3 microgram/ml of CSF and 57, 35, 27 microgram/ml of serum.

Two cases opf
bacterial meningitis
due to streptococci occurred following Pantopaque myelography. These are, to our knowledge, the first reports of Streptococcus mitus and group G streptococcus causing meningitis in this situation. These 2 cases emphasize the importance of considering the possibility of
bacterial meningitis
following myelography and the difficulty in differentiating it on clinical grounds from the more common
aseptic meningitis
that occurs after myelography. They also emphasize the importance of maintaining strict sterile technique during myelography.

Interleukin(IL)-6 levels were measured in cerebrospinal fluid (CSF) and serum samples from pediatric patients with central nervous system (CNS) infections by means of an enzyme-linked immunosorbent assay. Mean IL-6 concentrations in CSF samples from patients with
bacterial meningitis
(49,017 +/- 44,730 pg/ml) were significantly higher than those in patients with
aseptic meningitis
(1076 +/- 1572 pg/ml) or encephalitis (409 +/- 835 pg/ml). In
aseptic meningitis
and encephalitis, IL-6 levels in serum were within the lower ranges (< 100 pg/ml), in contrast with the highly elevated levels found in
bacterial meningitis
(14,332 +/- 18,385 pg/ml). In 5 of the 15 patients with encephalitis, elevated levels of IL-6 were observed in the initial CSF samples despite normal findings of routine CSF examinations. Also, sequential CSF samples revealed that there was an increase in the CSF cell count in two of the five patients. These results validated the potential of measuring IL-6 in CSF samples for the purpose of providing additional information on routine laboratory test results.

We examined the mechanism of increase of manganese superoxide dismutase (Mn SOD) in the cerebrospinal fluid (CSF) in
bacterial meningitis
(BM). The elevated levels of Mn SOD in the CSF in BM, measured with an enzyme immunoassay method, were more prominent than those in
aseptic meningitis
(AM) and encephalitis (EN). In AM and EN Mn SOD levels well correlated with levels of neuron-specific enolase and S-100b protein, which are markers of damages to nervous tissues, but did not with any of them in BM. CSF concentrations of tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 alpha (IL-1 alpha) were higher in BM than in AM and EN. From the serial measurements in BM, the peak values of these cytokines chronologically preceded or corresponded to those of Mn SOD. Immunohistochemically, a large number of the glial cells were stained for Mn SOD in the cerebral cortex from a patient with BM. By contrast, in the normal cerebral cortex, the glial cells were negative for Mn SOD staining. These results suggest that the marked increase of Mn SOD in the CSF in BM may be related to the increase of such cytokines as TNF-alpha and IL-1 alpha and that these cytokines may play a role in the induction of Mn SOD in nervous tissues.

Macrophage colony-stimulating factor (M-CSF) levels in the cerebrospinal fluid of 14 patients with meningitis and of 14 patients suffering from a disease other than meningitis were measured using an enzyme-linked immunosorbent assay. All four
bacterial meningitis
patients had M-CSF levels in the cerebrospinal fluid which exceeded 1540 U/ml, and the mean value was 3333 +/- 1481 U/ml. The mean M-CSF level in the cerebrospinal fluid of the ten
aseptic meningitis
patients was 393 +/- 175 U/ml, which was higher than that of patients who suffered from a disease other than meningitis (179 +/- 90 U/ml) (P < 0.01). There was no clear correlation between the M-CSF levels and the numbers of white blood cells, granulocytes, or monocytes in the cerebrospinal fluid. These elevated M-CSF levels were thought to be of a local origin, since most patients with high M-CSF levels in the cerebrospinal fluid had relatively low M-CSF levels in the serum.

We sought to determine whether the detection of cytokines, produced during the inflammatory response, would aid in the diagnosis of meningitis in young infants. We measured cerebrospinal fluid (CSF) and plasma levels of interleukin-6 (IL-6) and tumor necrosis factor (TNF) in 62 infants less than 6 months of age whose condition was evaluated for meningitis. Twenty infants had culture-proved meningitis, 22 had
aseptic meningitis
, and 20 control infants had no evidence of meningitis. The CSF IL-6 levels were elevated in all 20 infants with
bacterial meningitis
and in 9 of 22 infants with
aseptic meningitis
but were undetectable in all control subjects. Furthermore, CSF IL-6 levels were 10 times greater in infants with bacterial versus
aseptic meningitis
(p < 0.001). Levels of TNF in CSF were detected in 12 of 20 infants with
bacterial meningitis
and were undetectable in infants with
aseptic meningitis
and in control infants (p < 0.02). Plasma IL-6 and TNF levels were unreliable for the detection of meningitis in this patient population. We conclude that the presence of IL-6 in the CSF reliably identifies infants with meningitis and that the presence of CSF TNF is a highly specific indicator of bacterial meningeal inflammation.

Enzymatic determinations in cerebrospinal fluid (CSF) of aspartate aminotransferase (AST), lactic dehydrogenase (LDH), gammaglutamyl transpeptidase (GGT), creatine phosphokinase (CPK) and creatine kinase BB (CK-BB) were performed in 16 patients with
aseptic meningitis
(AM), in 25 children with
bacterial meningitis
(BM) and in 15 patients with meningism. The activity of AST and GGT was significantly higher in patients with BM on admission compared with those with AM and meningism (p < 0.05 and p < 0.005, respectively) and decreased with therapy. The highest concentration of AST and LDH appeared in patients with poor outcome as well as in those with ventriculomegaly on neurosonography (p < 0.05). The concentration of CK-BB increased in all patient groups on admission and remained higher on termination of therapy. The present study confirms the high activity of AST and GGT in BM patients in the CSF whereas the increased activity of AST and LDH reflects the extent of brain injury. Nevertheless, the prognosis for individual patients cannot be established on the basis of enzyme activity alone, but depends on several factors.
