The value of C reactive protein measurement in the differential diagnosis of meningitis was assessed in a population where tuberculous meningitis is prevalent. C reactive protein was measured serially with a sensitive radioimmunoassay in sera from 31 children with bacterial meningitis, 15 with tuberculous meningitis (6 with miliary tuberculosis), and 28 with viral meningitis. Concentrations of C reactive protein in patients with tuberculous meningitis lay between those of patients with bacterial and viral meningitis--a finding which detracts from the virtually absolute discrimination C reactive protein measurement allows between bacterial and viral meningitis. In all but two of the patients with tuberculous meningitis, C reactive protein concentrations fell rapidly after treatment began and became normal after 10 days. This fall did not, however, exclude the development of hydrocephalus as a complication. Measurement of C reactive protein remains a useful additional parameter in the diagnosis and management of the various types of meningitis.

The concentrations of metronidazole (Clont i.v.) in the cerebrospinal fluid were measured in 12 patients with viral meningitis or subsiding bacterial meningitis after a single infusion of 500 mg lasting 20 min. 1 h after infusion the CSF-concentrations were between 2,3 micrograms/ml and 7,4 micrograms/ml and 2 h after infusion between 6,5 micrograms/ml and 8,6 micrograms/ml. They attained 45,9% respectively 75,9% of the corresponding serum concentrations. Because the minimal inhibitory concentrations of the most important obligate anaerobic gram-negative bacteria are attained, it appears that metronidazole can be used for the treatment of bacterial meningitis caused by these pathogens.

Cerebrospinal fluid prostaglandin F2 alpha (CSF PGF2 alpha) levels were measured by radioimmunoassay in children as follows: Febrile convulsions (31 cases), epilepsies (32 cases), meningitides (31 cases) and non-neurological diseases (20 cases), totaling 114 cases. A 4.5-fold increase in CSF PGF2 alpha levels was seen in simple febrile convulsion, and a 2.5-fold increase in those with complex febrile convulsion as compared to those with non-neurological diseases. On the other hand, no increase in CSF PGF2 alpha levels was seen in children with epilepsy. When the body temperature was normal, the mean CSF PGF2 alpha levels showed no relation with age. When the body temperature was between 37.5 degrees C and 40 degrees C, the CSF PGF2 alpha levels in infants were higher than those in older children. The CSF PGF2 alpha levels in children with meningitis were high. The mean CSF PGF2 alpha levels in bacterial meningitis were not statistically (p greater than 0.05) different from those in viral meningitis. The CSF PGF2 alpha levels in meningitis were high on admission and gradually decreased with therapy. The results of our studies indicate that PGF2 alpha of the central nervous system markedly increased in infants and children with febrile convulsions or meningitis but not in those with epilepsy.

The results of cerebrospinal fluid (CSF) examination and other initial laboratory investigations have been analysed in one hundred and forty-nine patients with meningitis. The CSF differential leucocyte count clearly distinguished between bacterial and viral meningitis in 92 per cent of patients evaluated: CSF glucose and protein concentrations were less predictive by comparison. CSF glucose values were particularly unreliable because of hyperglycaemia in patients with bacterial meningitis and predictive accuracy increased when CSF levels were expressed as a percentage of blood glucose concentration. Results were not influenced by the age of the patients, and laboratory evidence of bacterial infection did not appear to be masked by prior antimicrobial therapy. A management algorithm based on the results of initial tests was applied retrospectively to the patients in whom Gram-stained CSF did not reveal bacteria. The algorithm indicated immediate antimicrobial therapy for all thirty patients with pyogenic infections, and for only one of sixty-three patients with a final diagnosis of viral meningitis.

Glutamic acid decarboxylase (GAD) activity in cerebrospinal fluid (CSF) was determined in 53 patients with neurological diseases as follows: Epilepsy (n:17), febrile convulsions (n:3), meningoencephalitis (n:17), encephalopathies (n:10), CNS leukemia (n:3), congenital hydrocephalus (n:2) and pseudoileus neonatorum (n:1). Compared with the mean normal value (5.2 +/- 2.5 pmol CO2 formed/hr/ml) reported in Part I, a significant increase of GAD activity in CSF was demonstrated in patients with uncontrolled epileptic seizures (11.4 +/- 3.9 pmol CO2 formed/hr/ml), febrile convulsions (13.5 +/- 8.7), viral meningitis with or without encephalitis (20.3 +/- 13.6), encephalopathies (30.0 +/- 25.9), CNS leukemia (11.1 +/- 5.0), congenital hydrocephalus (20.5 +/- 7.3) and pseudoileus neonatorum (28.6). Markedly high GAD activity was found in patients with CNS leukemia several days after intrathecal injection of methotrexate (39.8 +/- 18.0). On the other hand, significantly low GAD activity was shown in patients with bacterial meningitis or brain abscess (1.3 +/- 1.2). This suggests that some bacterial factors may be inhibitory toward GAD activity in CSF. High GAD activity in CSF may be useful as an indicator of aseptic brain dysfunction, although it was not always correlated with the severity of symptoms.

The ratio of glutamine to homocarnosine (G/H ratio) in CSF of children with meningeal pathology or convulsions was measured and the following results were obtained. 1. The mean G/H ratio of normal subjects was 83.0 +/- 41.4. 2. The mean G/H ratios of the patients with bacterial meningitis and meningeal leukemia were 115.9 +/- 81.9 and 115.2 +/- 49.2, respectively. Significant differences were found between those in normal subjects and these diseases. 3. The mean G/H ratio of the patients with viral meningitis was 80.0 +/- 35.1 and no significant difference was found between normal subjects and these patients. 4. The mean G/H ratios in the patients with controlled versus uncontrolled epilepsy were 130.9 +/- 67.1 and 74.8 +/- 49.4, respectively. A significant difference was found between normal subjects and the patients with controlled epilepsy. 5. The mean G/H ratio in the patients with febrile convulsions was 46.5 +/- 6.3. A significant difference was found between normal subjects and these patients. These data suggest that a high G/H ratio in CSF may indicate the excited state of the brain.

The level of C-reactive protein (CRP) was determined in the cerebrospinal fluid (CSF) by particle counting immunoassay. In non-neurological patients (N = 24), CRP was detectable only in 10 samples at concentrations ranging from 1.5 to 37 micrograms/l. The multiple sclerosis group did not differ from the controls. The highest CRP levels were found in viral and bacterial, including tuberculous, infections of the nervous system, with overlapping results for the various types of infections. However, in serum, the levels of CRP were much higher in pyogenic than in viral meningitis. We compared the CSF CRP/serum CRP ratio to the same ratio for albumin and found a significant correlation between the two ratios in viral, but not in bacterial, infections. These results suggest a local consumption of CRP during bacterial meningitis.

Lactic acid concentration has been determined in the cerebrospinal fluid (CSF) of 715 patients suffering from various neurological diseases. It was found to be most often elevated in cases of ischemic cerebral infarction, cerebral contusion, arteriosclerotic dementia, metastatic encephalitis, bacterial meningitis, menigiosis carcinomatosa and after epileptic seizures. In fewer cases lactate levels were increased with brain tumors, encephalitis, viral meningitis and radiculitis. Diagnostic relevance of CSF lactic acid determination is discussed with regard to ischemic cerebral disorders, differential diagnosis of viral and bacterial meningitis and for the confirmation of epileptic seizures.

The fluorescence method of Blume et al. was found to be useful for identification and morphological evaluation of lysosomes in cerebrospinal fluid cells. The investigations were carried out in 49 patients with viral and bacterial meningitis or meningismus. It was demonstrated that the CSF cells in most patients with purulent meningitis contained no fluorescent granules in an early stage of the disease before introduction of antibacterial therapy. These granules were found in CSF cells in cases of leptospirosis, viral meningitis and meningismus of various aetiology in acute stage of the disease and even in convalescence, and in purulent meningitis in convalescence. In bacterial meningitis large lysosomal granules were observed, and in viral meningitis these granules were small. The method visualizes easily bacteria (meningococci and pneumococci) in the cerebrospinal fluid.

Methods for rapid detection of viral antigens in cerebrospinal fluid (CSF) are needed to aid in the differentiation of viral from bacterial meningitis. The formation of precipitin bands in patients with suspect viral meningitis utilizing viral antisera in a counterimmunoelectrophoresis (CIE) system has been described. To investigate further the possible value of CIE in the diagnosis of viral meningitis, the specificity of the CSF precipitin bands was studied. Precipitin bands were formed between commercially available type-specific antisera and cell culture supernatant fluids. Precipitin bands were also formed when control CSF was used as an antigen. Using type-specific antisera produced against purified virus, enteroviral antigens were not detected in CSF from patients from whom CSF viruses had been isolated. CIE lacks sufficient sensitivity for the detection of echovirus 11 antigens in CSF.
