Adenylate kinase activity and lactate concentration were measured in the cerebrospinal fluid (CSF) of 5 patients with bacterial meningitis, of 4 patients with probable bacterial meningitis, and of 18 patients with serous meningitis. Furthermore, for comparison measurements were also performed in CSF of 27 patients with meningism. Concomitantly glutathione was measured in CSF in most of the patients. Significantly higher values of these 3 parameters were found in the CSF of patients with bacterial and probable bacterial meningitis compared with those having serous meningitis and meningism. Adenylate kinase activity and lactate concentration in patients with serous meningitis were significantly higher than in those with meningism. All patients with a clinical diagnosis of meningitis studied so far also displayed an adenylate kinase activity in their CSF. The determination of adenylate kinase, lactate and glutathione levels in CSF might be a useful aid for the diagnosis not only of meningitis but also for the discrimination between bacterial and serous meningitis.

Postoperative aseptic meningitis may occur as a complication of brain neurosurgery, especially after opening of the fourth ventricle. The picture of bacterial meningitis may be simulated. Main symptoms are persistent spiking fever, meningism and pleocytosis of CSF. The usually long lasting course can be dramatically shortened by early steroid therapy.

Neurological disorders may be, specially in children, the first and dramatic troubles giving notice of the hematological disease. These disorders, listed according to their frequency are: cerebral vascular thrombosis, epilepsy, bacterial meningitis, meningism, cerebral thrombo-phlebitis, disorders of cranial nerves, hydrocephalus related to a pachy meningitis. One must be cautious with transfusions. Paraclinical neurological tests have no specificity.

We reviewed the case records of 48 patients aged 60 years and older with a diagnosis of acute bacterial meningitis made during the period 1976-88. Predisposing conditions were present in 26 patients (54%) and concurrent infections in 24 patients (50%). Streptococcus pneumoniae accounted for 41% of all isolates and 56% were Gram-positive organisms. The most common symptoms were fever (79%), meningism (54%) and change in mental status (69%). Sixty-three per cent of the patients survived. Increased fatality was associated with absence of typical symptoms and signs and was presumably due to a delay in diagnosis. Other clinical and biochemical variables and antimicrobial therapy before admission to hospital and the presence of underlying disease were not associated with outcome.

Beta-2-microglobulin was determined in 147 patients admitted to hospital because of suspicion of CNS disease. Patients with meningism were chosen as control group. The concentration of beta-2-microglobulin in the spinal fluid of control patients was correlated with age. Reference values for 0-40 years were 0.34-1.58 mg/l. Above 40 years of age the values were 0.46-3.14 mg/l. CSF beta-2-microglobulin levels of patients with meningism, aseptic and bacterial meningitis overlap too much to be relevant in distinguishing between these entities. Five patients with herpes simplex encephalitis had markedly elevated levels ranging from 4.4 to 9.0 mg/l. Ten patients with herpes zoster-associated encephalitis had values from 1.1 to 6.1 mg/l. In the patient groups with CNS infections, the ratio of serum to spinal fluid beta-2-microglobulin was significantly more frequently less than 1 as compared with the meningism group, indicating intrathecal production of the protein. Further studies on the clinical relevance of CSF beta-2-microglobulin in the diagnosis of encephalitis seem warranted.

Serum creatine kinase was assessed in 94 consecutive patients without convulsions admitted to hospital due to suspicion of infection of the central nervous system. No reliable discrimination between patients with aseptic and those with bacterial meningitis was obtained. Patients with bacterial meningitis and brain oedema, as well as patients with encephalitis, had significantly higher values (P less than 0.01) than patients with meningism, aseptic meningitis and bacterial meningitis without cerebral oedema. Very high values, above 2500 U/1, were encountered in only the most severe cases of bacterial meningitis. The highest serum CK value found in patients with encephalitis was 725 U/l. Reference values for control patients with meningism were 16-269 U/1. In a subset of 9 patients creatine kinase isoenzyme analysis was performed. In all cases only muscle type (MM) isoenzyme was found.

Cerebrospinal fluid lymphocytosis (more than 50 percent lymphocytes or mononuclear cells) occurred in 14 of 103 cases of bacteriologically proved acute bacterial meningitis. Patients with cerebrospinal fluid lymphocytosis accounted for 32 percent (13 of 41) of all patients with bacterial meningitis with a cerebrospinal fluid white blood cell concentration of 1,000/mm3 or less. Cerebrospinal fluid lymphocytosis was significantly more common in neonates and in those without meningismus, but occurred in all ages and without any clear identifying clinical characteristics. The most common etiologic organisms were Streptococcus pneumonia (five), Neisseria meningitidis (two), and Hemophilus influenzae (two). Cerebrospinal fluid lymphocytosis is common in acute bacterial meningitis when the cerebrospinal fluid white blood cell concentration is below 1,000/mm3. It is therefore of little value in differentiating bacterial meningitis from viral, fungal, and tuberculous meningitis.

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.

Using the method of Park et al. the author studied spontaneous and stimulated NBT reduction by neutrophil granulocytes in the cerebrospinal fluid and blood, and by monocytic-reticular cells in the cerebrospinal fluid of the patients with bacterial and viral meningitis and meningismus. The author performed 333 investigations in 74 patients. Significantly higher mean values of the index of spontaneous and stimulated NBT reduction by the granulocytes and cerebrospinal fluid were observed in cases of bacterial meningitis as compared with the granulocytes of the peripheral blood in healthy subjects. It was demonstrated that in patients with bacterial meningitis blood and fluid granulocytes showed a similar phagocytic acitivty independent of the humoral environment. In the patients with bacterial and viral meningitis the monocytic-reticular cells the cerebrospinal fluid showed a similar, sometimes high, phagocytic activity depending on the phase and severity of the disease. On the otherhand, in most cases of meningismus these cells failed to manifest any phagocytic and bactericidal activity. In only few isolated cells in the fluid weak NBT reduction was observed. The obtained results of investigations showed the usefulness of the NBT test not only for the differential diagnosis of the aetiology of neuroinfections but also for the assessment of immune processes taking place in the nervous system.

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.
